Excess material collecting device for PVC wood grain sheet production and collecting process thereof

Abstract

The invention relates to the field of PVC wood grain sheets. The invention discloses an excess material collecting device for PVC wood grain sheet production. The device comprises a supporting plate, wherein the left side of the supporting plate is fixedly connected with a production machine, the left side of the top surface of the supporting plate is fixedly connected with two supporting rods, the top surfaces of the two supporting rods are rotatably connected with a first rotating rod, and two fixing blocks are fixedly connected to the left side of the top face of the supporting plate. The problem to be solved is that when a user winds wood grain sheets, flying dust is likely to be generated, and the working environment of the user is affected; and the excess materials need to be manually and regularly collected. When the device is used for cutting PVC wood grain sheets, the cutting effect is poor. The device is composed of a smoothing and scraping mechanism, a cutting mechanism and a transmission mechanism. According to the excess material collecting device for PVC wood grain sheet production and the collecting process thereof, the rotating rod rotates to drive a spiral blade to rotate to scrape and sweep the upper sides of the PVC wood grain sheets in the conveying process, and the possibility that dust and sundries adhere to the surfaces of the PVC wood grain sheets is reduced.

Description

technical field [0001] The invention relates to the related fields of PVC wood-grain sheets, in particular to a device for collecting waste materials used in the production of PVC wood-grain sheets and a collection process thereof. Background technique [0002] PVC veneer, commonly known as plastic veneer, is a widely used surface decoration material. According to the pattern or color, it can be divided into monochrome or wood grain, according to the hardness, it can be divided into PVC film and PVC sheet, and according to the brightness, it can be divided into matt and high gloss. According to the veneer process, it can be divided into flat decorative film and vacuum blister decorative film. [0003] In the process of producing and transporting PVC wood-grain sheets in the existing wood-grain sheet production equipment, the surface of PVC wood-grain sheets tends to adhere to the dust in the air, causing dust to be generated when the user rolls the wood-grain sheets , affe...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a waste material collection device for PVC wood grain sheet production and its collection process, which solves the problem of the existing waste material collection device for PVC wood grain film production. During the production and transportation process, the surface of the PVC wood grain sheet is easy to adhere to the dust in the air, causing dust to be generated when the user rolls the wood grain sheet, which affects the user's working environment; the device is producing PVC wood grain sheets It is necessary to cut the PVC wood grain sheet according to the required width. After cutting the PVC wood grain sheet, there will be a certain width of residual material. It is difficult for some existing devices to collect the residual material stably, and it needs to be thrown manually and regularly. It is time-consuming and labor-intensive to collect the remaining materials; when the existing device cuts the PVC wood-grain sheet, it directly cuts the PVC wood-grain sheet conveyed by the drive roller through the cutting knife, and the cutting effect is not good.
