Description

Efficient automatic production line for PVC processing and working method thereof

Technical Field

The invention belongs to the technical field of preparation of thermoplastic plastic products with high specific strength, large size and complex exterior structure, and particularly relates to a high-efficiency automatic production line for PVC processing and a working method thereof.

Background

The PVC mainly contains polyvinyl chloride, is yellowish, semitransparent and glossy. PVC, full name Polyvinylchlorid, is mainly composed of polyvinyl chloride, and other components are added to enhance heat resistance, toughness, ductility and the like. The top layer of the surface film is paint, the middle layer is polyvinyl chloride, and the bottom layer is back-coated adhesive. It is a synthetic material that is enjoyed, popular and widely used in the world today. Its global usage is second highest among various synthetic materials. It is only in 1995 a year that PVC has been statistically produced in europe at around five million tons and consumed at five million thirty million tons. In germany, the production and consumption of PVC averages one hundred and forty million tons. PVC is being produced and used worldwide at a 4% growth rate.

With the rapid development of social economy, the living standard and the living quality of people are continuously improved, the rhythm of people is continuously accelerated no matter in production or life, all walks of life realize automatic and intelligent production, and the production of PVC is the same.

The traditional PVC processing process depends on manual feeding, which not only has large workload and needs to consume a large amount of manpower and material resources, but also has an influence on the feeding speed of the whole production line because the manual feeding seriously influences the feeding speed, and at present, a plurality of enterprises adopt machine feeding, but only feed raw materials after blending, and still need to consume a large amount of manpower and time in the early stage, and cannot realize full-automatic feeding;

most of feeding sections of the existing planetary extruders only have a simple hopper function, but raw materials can be precipitated in the hopper for a long time, so that the materials are not uniform enough, the quality of products processed at the rear section is influenced, the extrusion efficiency of the existing extruders is low, and the production efficiency of the existing extruders is seriously influenced;

the pressure requirements of PVC sheets on the calender roll are different due to different customer requirements, different production batches, different raw materials and the like in the processing process, the space and the pressure of a plurality of current traction rolls are fixed, so that the application range of the PVC sheets is smaller, and the PVC films are not on the same plane before entering the calender roll, so that the PVC sheets are easy to wrinkle after entering the calender roll;

the PVC film is often subjected to edge removing processing due to different sizes required by customers in the processing process, however, most of the existing edge removing machines are operated on one side, the edge removing quality is affected due to the fact that the existing edge removing machines are prone to inclination in the processing process, the removed edge materials directly fall off to the ground and are collected by manpower alone, the manpower is consumed, and meanwhile, the influence on the surrounding environment is caused, and the influence on the production of equipment is also caused;

the traction roller is mainly used for traction of sheet raw materials in the production process of PVC, pressure requirements of PVC sheets on the traction roller are different due to different customer requirements, different production batches, different raw materials and the like in the processing process, the distance and the pressure of the current traction rollers are fixed, so that the requirements of enterprises on production cannot be met, and the PVC sheets often fall down on two sides of the traction roller in the conveying process;

the sheet material coiling machine is a mechanism for coiling PVC after production, and a plurality of sheet material coiling machines only carry out single coil collection at present, and the collected PVC film can be coiled continuously after being off-shelved by workers after the collection, so that a large amount of time is wasted, and the production efficiency is seriously influenced;

in conclusion, the existing PVC processing and producing equipment is still to be improved.
