Basic debugging method of medical mask machine
Medical masks are an indispensable material in hospitals. Whether for surgery or daily work, medical masks can well protect doctors and patients and prevent infection and spread of diseases. Medical mask machine is a machine specializing in the production of medical masks, and it is also a popular mechanical equipment.
After purchasing the medical mask machine, the manufacturer of the medical mask needs to debug the mask machine before it can operate and produce medical masks normally. The following is a detailed explanation of the basic debugging methods of medical mask machines by Strong H Machinery Technology Co., Ltd.
1. Turn on the start-stop switch and the power switch. The built-in light of the power switch is on.
2. Adjust the air pressure: the air pressure valve is under the workbench, and you can see the air pressure valve by opening the door of the equipment. Adjust the pressure according to the actual situation. When some mechanisms are not synchronized, increase the pressure. The working air pressure is generally at Adjust within the range of 0.2~0.6MPa.
3. Sound wave inspection and adjustment: (when the equipment is stopped)
(1) Turn on the power switch of the ultrasonic generator and press the “Sound wave test” switch. If the amplitude indicator index rises sharply and exceeds 100, it means that the frequency is too far from the resonance point. The “sound wave adjustment” knob must be adjusted. Look at the amplitude indicator. Press the “Sound Wave Inspection” check switch with the left hand (not more than 3 seconds), and turn the “Sound Wave Adjustment” knob with the right hand to adjust the pointer of the amplitude display to the lowest point. When adjusting, if the amplitude indicator indicator is not falling but rising”, turn the “Sound Wave Adjustment” knob in the opposite direction. The reading of the amplitude indicator indicator is within 50. The reading of the ammeter indicator is below 0.6A is the best working condition. After adjusting the sound wave Tighten the butterfly nut and close the protective cover.
(2) During the no-load test, if the “overload indicator light” is on, it means there is a problem with the equipment. It is not allowed to start working at this time. You must shut down and check the cause, and then start working after troubleshooting.
4. the inspection of the cooling fan: check whether the cooling fan is working normally. To ensure that the ultrasonic transducer can work for a long time when it is working.
5. Check whether the pneumatic parts are abnormal.

Introduction of cosmetic pump head
Cosmetic pump heads are cosmetic packaging materials that are widely used in various facial cleansers and liquid foundations. This article gives a detailed introduction to the pump heads. Provided by Wuxi Meishang Packaging Technology Co., Ltd., a cleansing foam pump manufacturer.
Surface hardness of cosmetic pressure pump: The surface hardness of PP is low among the five general plastics, and only better than PE. When the crystallinity is higher, the hardness will increase accordingly, but it is still not as good as PVC, PS, ABS, etc.
Thermal properties: Among the five general plastics, PP has good heat resistance. PP plastic products can work for a long time at 100°C. When there is no external force, PP products will not deform when heated to 150°C. After the nucleating agent is used to improve the crystalline state of PP, its heat resistance can be further improved, and it can even be used to make utensils for heating food in a microwave oven. Therefore, the quality of the cosmetic foam pressure pump is very durable.
Cosmetic pump head is a high molecular compound polymerized by addition polymerization or polycondensation reaction with monomer as raw material. Its resistance to deformation is moderate, between fiber and rubber. It is composed of synthetic resin and filler, plasticizer and stabilizer. , Lubricants, pigments and other additives.
The main component of plastic is resin. Resin refers to a polymer compound that has not been mixed with various additives. The term resin was originally named for the lipid secreted by plants and animals, such as rosin and shellac. The resin accounts for about 40% to 100% of the total weight of the plastic. The basic properties of plastics are mainly determined by the nature of the resin, but additives also play an important role. The condition for calculating the strength of the cavity wall thickness is that the stress value of the cavity under various stress forms shall not exceed the allowable stress of the mold material. Some foam cleansing milk pump heads are basically composed of synthetic resin, with no or little additives, such as plexiglass, polybenthylene, etc.
Wuxi Meishang Packaging Technology Co., Ltd. specializes in the production of sprayers and plastic pump heads. The key products are hand buckle spray guns, perfume nozzles, caps, moisturizing lotion pumps, skin care pump heads, shampoo pump heads, disinfectant nozzles and other products.

Performance indicators of electric vehicle cooling fans
The cooling fan of an electric vehicle is an important part of the cooling system. When designing the cooling fan, the following performance indicators need to be met to be called a qualified vehicle cooling fan to achieve the effect of heat dissipation.
1) Output power
Under the specified requirements, the speed of the cooling fan generally requires 1600-4000r/min, and the rated power can only be reached when the rated speed is reached. For the cooling fan, it is necessary to ensure that it can output at full load for a long time.
2) Start control
The starting process refers to the process in which the motor speed rises from zero to a stable value. For a brushless DC motor, due to its small internal resistance, the current rapidly increases when starting, which will cause the back EMF to increase, and it will also suppress the current increase. After the current increase reaches the maximum value, it will start to decrease. The current at starting is much larger than the stable operating current, which is about 6-7 times the stable current. The power circuit will bear a larger current and electromagnetic interference will also be great. Starting performance is one of the key indicators of cooling fans. Generally speaking, it is required to be safe, reliable, fast and stable, and can be started and stopped at will.
3) Working voltage
Taking new energy vehicles as an example, the requirements for cooling fans working in 12V systems are as follows:
Does not work below 9V
9-16V normal work
16-18V shutdown, but cannot be damaged
18-24V can withstand at least 1h
The control circuit above 24V is damaged and protected by a fuse.
4) Noise control
Generally speaking, the higher the speed, the greater the air volume, and the greater the noise. At present, the general size of cooling fans is relatively large, and most of the cooling fans rotate at 1600-4000r/min. There are special noise testing methods for noise, which need to be optimized from both hardware and software aspects.
In addition to the above four goals, the designed electric fan also needs to have motor protection mechanisms, such as stall protection, short circuit protection and overcurrent protection, overvoltage protection and undervoltage protection.
Buying the automobile cooling fan sold by Suzhou Santian Precision Mould Co., Ltd. not only meets the above indicators, but also has a favorable price, and provides comprehensive after-sales service. If you have any needs, please contact us.

Choice of cosmetic packaging material color
High-quality cosmetic packaging materials are not only good quality, but also the choice of color. Cosmetic packaging materials of different colors will give consumers different impressions. Wuxi Meishang Packaging Technology Co., Ltd. teaches you how to choose the color of cosmetic packaging materials correctly.
When we buy cosmetics, we first see the packaging of skin care products. Only if the packaging is attractive enough, will we be interested in understanding the product efficacy, price, or trying the product; while the brand is designing the product bottle, in addition to considering the skin care package. In addition to whether the product will chemically react with the bottle, it will also convey information such as product efficacy, product positioning, and product brand concept.
The first is the packaging material, the shape can be divided into transparent and opaque.
There are many skin care products that choose transparent materials, because they transmit light and show a sense of advanced. This kind of information conveys a variety of things, but there is a commonality, that is, they all feel refreshing and not greasy when used, and are suitable for use in spring and summer.
Choose skin care products with opaque materials for three reasons:
1. The paste is oily and moisturizing. After the transparent material is used, there will be residues on the bottle body during customer use, which will affect the product image
2. The main products are people-friendly and affordable, and the cost of packaging materials is lower than that of transparent materials such as glass and acrylic, such as the old Dabao face cream
3. The product is aimed at mothers and babies or the main product is sensitive, the material color is slightly milky and it looks mild, and the material is similar to the medicine packaging. Next is the color of the bottle
Skin care products in cool colors, such as blue, are reminiscent of the sea and blue sky. These products are refreshing, that is, they are not greasy when used, and are more suitable for spring and summer.
Warm color packaging will make people feel warm and soft. These products are oily and moisturizing, that is, for dry skin, they are more suitable for autumn and winter use.
Dark colors such as red, green, and blue packaging are mostly aimed at mother-in-law women or men’s skin care products
Transparent and colorless, or intermediate white is more common, black and gray are mainly used in men’s skin care products
There are also some other colors that reflect product characteristics. For example, green is mostly used for natural herbs, and pink is mainly used to brighten skin tone and enhance complexion.
Maison Packaging Technology Co., Ltd. sells various cosmetic packaging materials in bulk, including glass bottles, plastic bottles, perfume nozzles and lotion pumps. Our raw materials meet the international cosmetic packaging standards and the craftsmanship is exquisite, but the price is lower than that of our peers in the industry. Now we are seeking partners from all over the world. If you are interested, please contact us!
