Q:For example, three roller calender, the size of the three roller models are the same, or is there a big difference?

Are the same, that is, there is a spindle, two transmission shaft, 3 roller diameter is 18 inches

Q:What brand is good blister machine?

Some people like bamboo chopsticks, some people like wood chopsticks, and there is a penny for each other, and decide for yourself

Q:Is the roller mill in the plastics industry a special type of work?

Material temperature to about 150 degrees to shape, in high temperature, a large number of plasticizers, smoke volatilization. Exposure to lead smoke, hydrogen chloride gas and so on.Remark: only the molding workers who produce PVC products are limitedFor more details, please see:Reply of the Ministry of personnel on light industrial labor jobs early retirementScope of work for early retirement of light industry

Q:What is the difference between injection molding machine and plastic suction machine?

Only with injection molding machines. Custom molds are required.

Q:PVC blow molding and rolling film difference

Blow molding: a method of forming a hollow product by expanding a hot melt parison closed in a mold by means of a gas pressure,

Q:What does blister machine do?

Plastic machine is mainly divided into two categories, one is used for production of billboards, a film for sliding door

Q:How to choose an automatic plastic suction machine?

1. accessories. The main configuration of the JUNSAI machine is its soul, and buyers must not ignore the configuration simply by drawing cheap. Many amateurs buy the machine back, found that many of the configuration is not installed, and it will be more expensive to return. Contrast is what brand accessories, whether or not with water cooler, vacuum pump, general air compressor is with their own. Jun Jing competition from Japan Toshiba procurement of electronic parts, absolute quality assurance. Of course, the import configuration is more stable than the domestic configuration.

Q:Characteristic parameters of calender

2. Power calculation:Power consumption is also an important parameter in the design of calender, and it is difficult to obtain it accurately by theoretical formula. Several empirical formulas are briefly described here, which are approximately calculated:1) the power calculation of a single motor driveA, according to roller linear speed calculationN, =a, L, VFormula a -- Calculation factorL - roller work part lengthV - calendering speedB. is calculated by the number of rollersN=K, L, nFormula K -- Calculation factorL - roller work part lengthN - number of rollers.The common disadvantage of the above two methods is that they do not consider the nature of the processed rubber material and the processing method, and the influence of the roller diameter on the power, and their influence on the power consumption is very large. It can be seen that the above two formulas are one-sided.C. analog computingBy using the known machine characteristics and power consumption, the calculation coefficients a and K are calculated, and the power of the calender is designed by using the upper model.2) the power calculation of multiple motors in transmissionBecause each roller has different positions and process uses, the speed of the rolling line is different, and the power consumed by each roller is different in the process of rolling. Under normal conditions, the feed roller consumes much more power than the roll.A, when rolling, the power consumption of two rollers is proportional to the roller linear speedIf the linear speed of two rollers is V1, V2, and the power is N1 and N2, respectively:N1/N2==V1/V2The power consumed by B and glue is only 6% of the total powerN =0.06N total NN sticking - rubber roller power,N total effective total power,ETA - total transmission efficiency.According to the above two points, you can calculate the power of each roller.

Q:I want to buy a new fully automatic blister machine. I wonder if that made brand is good What's the price? How many pieces can be produced in a day with a 1000*450 thick plastic suction disk?

Nanjing jieter blister machine production, good quality, quality and performance of the equipment are good, high working efficiency, strong pressure, good molding effect; hydraulic self-locking function, good safety; their products through the EU CE certification. The key is their customer service service is better, if the equipment problems, no repair, closed the case as of great loss, if the purchase of Nanjing jieter blister machine, will not let you have the menace from the rear

Q:The processing technology of PVC calendering film?

Characterized by high yield and good quality. But the process equipment is complex, and the investment is large. Soft rolled film thickness generally below 0.25mm, formulations plasticizer content greater than 25phr. PVC calendered film occupies an important position in the plastic film, the cover, Yantian industrial packaging, electrical insulation, pneumatic products, advertising light boxes, waterproofing, commodity packaging, etc. have a wide range of applications.
