Automatic high and low mixing system

Principle of batch cumulative weighing batching system

With the development of high filling masterbatch, PVC extrusion processing to scale direction, advanced material pretreatment system has been essential, it is to ensure the realization of high yield, high quality and low price of the first condition. In the high filling masterbatch, PVC extrusion processing industry, the traditional mixing method is: hot mixing, cold mixing with artificial ingredients and transportation.

Product introduction:

At present, the batching system which is controlled by computer automation is the core, supplemented by pneumatic conveying, combined with hot and cold mixer, so as to form a complete set of high filling masterbatch, PVC batching and mixing automatic production line.

Advantages of automatic high and low mixing system equipment:

1. The automatic batching system controlled by computer improves the batching accuracy, and solves the problems of complicated manual batching, material loss and chemical harm to the operator.

2. The efficient pneumatic conveying system replaces the heavy labor in the process of mass material handling and improves the production efficiency.

3. The material handling process is completely carried out in the closed pipeline, avoiding the pollution of dust to the workshop environment and the harm to workers.

4. The material preparation and processing process is more centralized, more efficient, and the output is higher, which can fully meet the needs of mass production.

High speed side direction feeding system

Double-cone forced feeding machine has the advantages of continuous conveying and automatic cleaning. The material is nipped by the feeding device, the continuous average supply machine is swallowed in, and the speed regulation system of the double cone forced feeder can adjust the size of the feed quantity, thus replacing the manual feeding operation and avoiding the uneven feeding. It is easy to produce safety accidents, and the purpose of saving, safety and high efficiency is the feeding equipment which is often used in high filling and double cone forced feeding machine. Double cone forced feeding machine description: adopt special self-junction meshing screw to feed, seal well without leakage, double cone forced feeding machine has strong forward connection Continuous conveying Materials give full play to the advantage of Assembly Line processing
 
1. high precision modular extrusion design
2. High torque deceleration gear box
3. High speed to enhance the delivery capacity

Volumetric feeding system

The screw feeder detects the weight of the material passing through the weight bridge to determine the weight of the material on the tape, the digital speed sensor installed in the tail, and continuously measures the running speed of the feeder. The pulse output of the speed sensor is proportional to the speed of the feeder, the speed signal and the weight signal are fed into the feeder controller together. The microprocessor in the controller processes it to generate and display the accumulative amount / instantaneous flow rate. The flow rate is compared with the set flow rate. The frequency converter is controlled by the output signal of the control instrument to change the driving speed of the feeder, so that the material flow on the feeder changes, approaching and maintaining the set feed flow rate. In order to achieve the requirement of quantitative feeding.
1. Small size, light weight, simple and compact structure;
2, easy installation and maintenance, low operating costs;
3. Low efficiency and large feeding capacity;
4. Low noise, good for improving working environment;
5. Low power consumption and high power factor;
6. The equipment works in the resonant state, so the amplitude is stable, the operation is reliable, and the adaptability to various materials is strong;
7, add motor governor without adjusting the eccentric block can be conveniently stepless adjust the feed

Loss-in-weight feeding system

Gravity type feeder suitable range including plastic material, powder, calcium carbonate, talcum powder, resin membrane powder, flour, starch, etc., which according to different raw materials, we have designed two kinds of different scale, namely powder scale (solve the liquidity is poor feeding measuring feeding problems), the aggregate balance bridge (solve any possible problem), very good to solve the problems in the existing production process.
Advantages:
(1) wide application range, granule, powder, calcium carbonate, talcum powder, resin film powder granule, flour, starch can be used;
(2) the mechanical components of the weightless feeder, such as screw, are easy to decompose, simple to assemble and easy to clean;
(3) stable blanking performance, high precision, large optional range of conveying capacity;
(4) the static accuracy of weightless feeder reaches 0.1%;The dynamic accuracy of linearity and repeatability reached 0.3%.
(5) the control instrument of weightlessness scale is rwc-800cf with high precision, strong anti-interference and good real-time performance. The sensor adopts Ronan high-precision sensor module, and the sensor is sealed by laser welding, which has the advantages of high precision and good reliability, especially suitable for the application site with poor working conditions.
(6) weightless feeder control system has strong flexibility: the weightless scale control system can realize manual and automatic control of feeding and feeding treatment, and realize manual and automatic conversion
