Description

Technical Field

[0001] The utility model belongs to the technical field of plastic processing, and in particular relates to a plastic mechanical processing and cutting device. Background Art

[0002] Plastic is a high-molecular compound made from monomers through addition polymerization or condensation polymerization. Microplastics can harm human health. Its anti-plastic has medium deformation ability, between fiber and rubber, and is composed of synthetic resins and fillers, plasticizers, stabilizers, lubricants, colorants and other additives.

The extrusion plate squeezes the pressure plate to drive the clamping plates to approach each other, that is, the clamping plates clamp the plastic product, and the hydraulic cylinder continues to extend to cut, and after cutting, the hydraulic cylinder contracts and drives the extrusion plate to move up, and the clamping plate releases the plastic product under the action of the elastic force of the elastic member, and the plastic product can be removed. In this process, the plastic product is automatically clamped for cutting and then automatically released, and the operator cannot manually clamp or release it, so the process is more convenient and efficient. Plastic will produce debris during cutting. If the debris is not cleaned in time, it will easily affect the cutting accuracy of the plastic during cutting. The debris produced by cutting will splash, making it inconvenient to clean the debris uniformly, which will easily reduce the working efficiency of the cutting device. Utility Model Content

[0018] 1. In the utility model, a collecting assembly is provided. When the mounting cover drives the cutting blade to move upward, the mounting cover drives the driving rack to move upward, so that the transmission gear roller rotates on the side wall of the mounting plate through the rotating shaft. At this time, the cover plate is driven to move through the connecting rod under the action of the driven rack. As the cover plate moves, the plastic debris on the cover plate is pushed into the cutting table under the action of the inner wall of the shell cavity of the cutting table. When the plastic debris in the cutting table reaches a certain amount, the baffle is lifted upward and the debris is cleaned out through the drain chute.

A mounting plate 83 is fixedly installed on the inner wall of the top surface of the cutting table 1. A transmission gear roller 84 is rotatably installed on the side wall of the mounting plate 83 through a rotating shaft. The transmission gear roller 84 is meshed and connected with the driving rack 82 and the driven rack 86.

[0029] The specific implementation method is as follows: the electric telescopic rod 7 drives the cutting blade 11 to cut the plastic through the mounting cover 10, and the cut plastic debris will fall on the cover plate 81. When the mounting cover 10 drives the cutting blade 11 to move upward, the mounting cover 10 will drive the driving rack 82 to move upward, so that the transmission gear roller 84 rotates on the side wall of the mounting plate 83 through the rotating shaft. At this time, under the action of the driven rack 86, the cover plate 81 will be driven to move through the connecting rod 85. As the cover plate 81 moves, the plastic debris on the cover plate 81 is pushed into the cutting table 1 under the action of the inner wall of the shell cavity of the cutting table 1.

[0031] The specific implementation method is as follows: the plastic to be processed is placed on the upper surface of the cutting table 1, and then the driving motor 41 drives the bidirectional threaded rod 42 to rotate. Under the action of the thread, the moving sleeve 43 moves in the stroke groove 2, thereby driving the positioning column 44 to move synchronously. When moving, the positioning column 44 will limit the plastic and make the plastic located at the center of the cutting table 1. The limit pin 46 will change according to the shape of the plastic under the action of the limit spring 45, and the limit pin 46 that is not squeezed will limit the upper part of the plastic.

When moving, the positioning column 44 will limit the plastic and make the plastic located at the center of the cutting table 1. The limit pin 46 will change according to the shape of the plastic under the action of the limit spring 45. The limit pin 46 that is not squeezed will limit the upper part of the plastic.

When the mounting cover 10 drives the cutting blade 11 to move upward, the mounting cover 10 will drive the driving rack 82 to move upward, so that the transmission gear roller 84 rotates on the side wall of the mounting plate 83 through the rotating shaft. At this time, under the action of the driven rack 86, the cover plate 81 will be driven to move through the connecting rod 85. As the cover plate 81 moves, the plastic debris on the cover plate 81 is pushed into the cutting table 1 under the action of the inner wall of the shell cavity of the cutting table 1.
