A cutting device for processing plastic sheets

Abstract

This utility model belongs to the field of plastics technology, and in particular to a cutting device for processing plastic sheets. It includes a placement plate, a fixed plate at the bottom of the placement plate, a first motor on one side of the fixed plate, a threaded rotating shaft connected to the output end of the first motor, a movable block threadedly connected to the surface of the threaded rotating shaft, a connecting block at the top of the movable block, a fixed base plate connected to the top of the connecting block, and a support frame at the top of the fixed base plate. A second threaded shaft drives a second sprocket to rotate, which in turn drives a first sprocket via a first chain to rotate, which in turn drives the first threaded shaft to rotate. This, in turn, causes the first and second threaded shafts to move a pressure plate downwards, pressing and fixing the cut edge of the plastic sheet, increasing stability during cutting and preventing damage to the plastic sheet from the force applied during cutting, thus improving the cutting effect.

Description

Technical Field

[0001] This utility model belongs to the field of plastics technology, and specifically relates to a cutting device for processing plastic sheets. Background Technology

[0002] Plastics are polymeric compounds formed by polymerization of monomers through addition or condensation reactions. They possess moderate resistance to deformation, falling between fibers and rubber, and are composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. The main component of plastics is resin. Resin refers to the polymeric compound before it is mixed with various additives. The term "resin" originally derived from lipids secreted by plants and animals, such as rosin and shellac. Resin accounts for approximately 40% to 100% of the total weight of plastics. The basic properties of plastics are primarily determined by the nature of the resin, but additives also play an important role. Some plastics are essentially composed of synthetic resins, containing little or no additives, such as plexiglass.

[0003] Currently, plastic sheets need to be cut during production and processing. However, general cutting equipment cannot adequately protect the plastic sheets during use, and the cutting force can damage them, affecting their performance. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a cutting device for processing plastic sheets, which solves the problem that the plastic sheets cannot be adequately protected and that the cutting force can cause damage to the plastic sheets.

[0007] Preferably, a second protective cover is provided on the outer side of the cutting disc, and a first fixing block is provided on each side of the second protective cover. A bolt is provided at one end of the first fixing block, and one end of the bolt passes through the first fixing block and is threadedly connected to the placement plate.

[0008] Preferably, a sliding rod is provided on one side of the fixed plate, and one end of the sliding rod slides through the moving block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In use, place the plastic sheet on the surface of the fixed base plate, then turn the handle. The handle moves the threaded rod via the turntable, causing the threaded rod to move the fixed plate downwards, thus pressing and fixing the plastic sheet. Simultaneously, the third motor operates, causing the third motor to drive the fourth sprocket via the first rotating shaft. The fourth sprocket, through the second chain, drives the third sprocket, which in turn drives the second threaded shaft.

Both the first and second threaded shafts cause the surface pressure plate to move downwards, pressing and fixing the cut edge of the plastic sheet. This increases stability during cutting and prevents damage to the plastic sheet caused by excessive force, thus improving the cutting effect. Attached Figure Description
