Description

Automatic lamination production line and method of PVC composite floor silent mat

technical field

The invention relates to an automatic production equipment for panels, and more particularly, to an automatic film-covering production line and method for PVC composite floor mute pads.

Background technique

With the improvement of housing conditions, people's requirements for the indoor environment are increasing day by day. The raw materials of traditional solid wood floors have a long growth cycle, high prices, low surface hardness, easy to mold, and poor fire and water resistance. For this reason, people tend to use Green environmental protection, fireproof, waterproof, scratch-resistant and wear-resistant PVC floor, this kind of floor can also be divided into wood-plastic floor (WPC) and stone-plastic floor (SPC) and other types, among which WPC floor with solid wood material and stone material are added. The SPC floor not only absorbs many advantages of PVC floor, but also has the advantages of beautiful and high-grade, easy to lay and so on, and can better meet people's requirements of aesthetics, cost performance, practicality and so on. However, this type of floor also has the disadvantage of poor sound insulation performance. The noise generated by people walking or objects falling on the substrate is easy to disturb the life and rest of family members and neighbors. For this reason, people need a PVC floor with a silent pad. . As the PVC mute mat covered floor is a new type of floor, the related production and manufacturing equipment is still in the process of continuous improvement. At present, some processes in the silent floor manufacturing industry still require a lot of manpower for simple handling and stacking operations, and the PVC mute floor is still in the process of continuous improvement. There are unnecessary time loss, material waste and dust hazards in the manufacturing process of the padded membrane floor. The laminating technology of the floor also has disadvantages such as high production cost, time-consuming, low lamination accuracy, and the membrane is easy to fall off. Traditional processes are optimized to improve production efficiency and product quality, making products more environmentally friendly.

The traditional processing procedure is as follows:

1) Two people put the front and back stacked substrates, front side up, neatly to the roller coater for roller coating;

2) Two people unload and manually turn the board to send the substrate to the veneer dryer;

3) After two people take out the substrate from the veneer dryer and stack it, one person drives the forklift to transport the substrate for maintenance for 48 hours;

4) One person drives the forklift to transport the maintained substrate to the substrate cutting machine, two people load the material, after the cutting machine cuts, two people unload and inspect, and one person stacks;

5) One person opens the forklift to send the palletized substrates to the filming station, and two people carry out traditional manual filming or small plate filming, and then two people stack the films after filming.

The defects of the above-mentioned prior art are:

In the traditional process, ordinary multi-blade saws are often used to cut the substrate, which not only generates a lot of dust but also wastes a part of the substrate;

The traditional process mostly uses manual filming or small plate lamination to fit the mute pad, which is easy to cause problems such as low film accuracy and easy falling off; the unreasonable arrangement of manual filming or small plate lamination and maintenance process also seriously affects production efficiency;

The whole process requires a lot of manpower for transportation and flipping. The labor intensity of workers is very high, and long-term continuous work is easy to accumulate fatigue, which reduces product quality. Some factories have insufficient protective measures for equipment, and workers are prone to accidents when they are fatigued. Workers work in high temperature, dust and noise environments for a long time, which can easily affect their physical and mental health.

after every 5 piles of 25 base plates are stacked on the material storage stacking platform, a stacking manipulator (121) of the double-station stacker crane (12) compresses tightly and clamps the base plates, the left side stacking is finished firstly, then the right side stacking is carried out, and the base plates are transported to a specified position by a forklift for maintenance treatment after stacking.

6. The automatic laminating production method of the silencing pad of the PVC composite floor as claimed in claim 5, is characterized in that: and a disc-shaped emergency stop device (51) is arranged on the continuous plate turnover device (5).

7. The automatic laminating production method of the silencing pad of the PVC composite floor as claimed in claim 5, is characterized in that: the punching device (8) is provided with a grating emergency stop protection device.
