PVC profile (pipe) compounding PVC transparent pipe production line is an automatic production line specially designed for PVC profiles and pipes. The automatic production line is centered on the batching unit and the mixing unit, combined with storage, transportation, automatic control and other units, the entire production process is automated, and the production process and production data reports are directly controlled and output by the host computer. The whole production line can realize the whole-process linkage control or the independent control of each unit, which greatly facilitates the production operation and the maintenance of the production line. For the batching unit, we use the world's most advanced instruments and equipment and our professionally designed and manufactured metering and batching screw for the batching unit, which ensures the accuracy of batching and the speed of batching. Mixing unit We can provide you with the most advanced mixer in the world to ensure the output and quality of the entire production line.

1 Introduction

 Our company can provide general contracting business of PE pipe production line, including whole plant design, commissioning of all equipment and turnkey projects. We can provide customers with:

a: A complete set of design technical documents;

b: Provide technical documents of all equipment, including extruder, die, utilities (water, gas, electricity);

c: Provide equipment debugging and process inspection for the general contracting project of the whole plant;

d: Provide technical and staff training for customers;

e: According to the needs of the customer, technicians can be sent to work in the other party's factory for 1-2 years to ensure the successful implementation of the project.

2. System flow:

3. Performance characteristics of high-speed mixer manufacturers:

A: Various feeding forms such as dense phase pneumatic conveying system, roots air conveying and vacuum feeding are adopted

According to the actual situation, the corresponding conveying form is adopted.

B: Bag opening station

1. Uniform size, beautiful appearance, low labor intensity, and ergonomic.

2. Equipped with a vibrating screen, which can screen out sundries.

3. There is a sound and light alarm on the top, which is clear at a glance.

4. It is in a state of slight negative pressure when working, and there is no dust.

5. There is a dust-proof lamp inside, which can clearly see the material condition.

C: Loading hopper

1. The upper hopper is an integral fluid hopper.

2. The upper hopper is evenly distributed and beautiful, which greatly reduces the space occupied by the volume (the effective volume remains unchanged)

3. The feeding hopper of CaCO3 material adopts forced feeding.

4. There is an inspection hole, open the hole cover door, you can clean it.

5. The material level meter specially used for ultra-fine powder occasions is adopted.

D: screw feeder

1. The feeder adopts low-speed high-torque motor, frequency conversion control, and large adjustment range.

2. The screw seal is kept away from powder.

3. The cantilever screw is adopted to reduce the sealing points, and the maintenance is particularly convenient.

4. Fully sealed connection with weighing bucket.

5. Depending on the material, spray the fluoroplastic spirally on the material with high viscosity.

E: Weighing batching system

1. Diversity of formulas, up to 100 kinds of materials, formulas can be changed within a certain range, such as feeding amount, feeding sequence, feeding speed, etc.

2. A residual material processing device is added inside the scale body.

3. The conveying method of PVC conveying and auxiliary material conveying in the same pipeline is adopted. Using the same conveying pipeline, the auxiliary materials can be sent into the intermediate hopper completely and cleanly, and there is absolutely no phenomenon of auxiliary materials sticking. And when entering the mixer, it enters into a flower shape with PVC, which is beneficial for the mixer to work more efficiently.

4. Using the batching instrument produced by UNIPULSE, it can store and control the dosage of 100 kinds of materials, with great changes and wide applicability.

5. A set of weighing and batching system can manage different batch numbers and formulas at the same time, and it is controlled by computer for automatic weighing and feeding.

6. The weighing accuracy level is 0.2

F, the system dust is small

1. All soft connections adopt sandwich structure, material and gas are separated.

2. Where there is dust source in the material flow process, there are dust removal pipelines or air vents.

3. The system is a fully enclosed structure.

G. Electric control unit

1. Centralized and decentralized control system using field bus network.

2. The control principle of separate PLC and mutual communication is adopted, so that the whole system is both controlled and independent of each other, and only needs to be connected with PLC in the last and later projects to form a large system with both joint control work and mutual independence.

3. The measuring instrument adopts the F800 batching instrument customized by our company in Japan.

4. Adopt imported cantilever beam bellows weighing sensor.

5. Two-way data exchange between measuring instrument and PLC and computer.

6. The computer realizes the comprehensive display of the technological process, forms a general picture and a sub-picture, and displays the working status of each equipment with the picture. Such as: running, stopping, feeding, etc.

7. The computer has real-time report and historical report record printing function.

H, finished product silo

1. Adopt integral flow hopper.

2. The decompression device is adopted to prevent the occurrence of adverse phenomena such as jet flow.

The finished material is screwed again before being fed into the extruder, which is conducive to the maximum homogenization of the material.
