PVC film preparing and processing system and preparing and processing method

Abstract

The invention relates to a PVC film preparing and processing system and a preparing and processing method. The PVC film preparing and processing system comprises a bottom plate, a feeding device, a cutting device and an abutting device; the feeding device is installed on the bottom plate, and the cutting device and the abutting device are installed on the feeding device. According to the PVC film preparing and processing system and the preparing and processing method, the following problems existing when a PVC film roll is cut can be solved, wherein firstly, when the PVC film roll is cut, the PVC film roll is mostly manually placed on a clamping tool, then a cutting knife is used for cutting the PVC film roll which is clamped and positioned, notches of the PVC film roll which is manually cut are not uniform, and the attractiveness of the PVC film roll is influenced; and secondly, manual equal-length cutting operation cannot be carried out on the PVC film roll, so that the lengths of the cut PVC film roll are inconsistent, the production quality of the PVC film roll is influenced, re-cutting operation needs to be carried out, and the cutting efficiency of the PVC film roll is reduced.

Description

technical field [0001] The invention relates to the technical field of PVC film production and preparation, in particular to a PVC film preparation and processing system and a preparation and processing method. Background technique [0002] PVC is one of the five general-purpose synthetic resins in synthetic materials. Its output is second only to polyethylene. It is widely used in construction industry, packaging materials, household daily necessities and automobile industry. The main component of PVC film is polyvinyl chloride, and other components are added to it. Enhance its heat resistance, toughness, ductility, etc. The top layer of this surface film is paint, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive. After the PVC film is rolled, it needs to be cut into PVC film rolls of the same length for convenience. Packaging operations of PVC film. [0003] However, the current PVC film rolls have the following problem...

AI Technical Summary

Problems solved by technology

[0003] However, the current PVC film rolls have the following problems when they are cut. One, at present, when the PVC film rolls are being cut, most of them are manually placed on the clamping tool, and then the clamp is clamped with a cutting knife. Carry out the cutting operation with the finished PVC film roll, the artificially cut PVC film roll has uneven incision, which affects the aesthetics of the PVC film roll; 2. Manually cannot perform equal-length cutting operations on the PVC film roll, making the PVC film The length of the rolls is inconsistent after cutting, which affects the production quality of PVC film rolls, and requires re-cutting operations, which reduces the cutting efficiency of PVC film rolls
