A kind of cutting device for plastic product residue with controllable cutting size

Abstract

The invention discloses a plastic product leftover material cutting device capable of controlling the cutting dimension. The other end of a connecting rod is fixedly connected with a compression device, and a fixing rod is movably inserted into the other end of the compression device. The end, located outside the compression device, of the fixing rod is fixedly connected with a rotary disc. A cutting knife is fixedly connected to the edge of the other end of the rotary disc. A first contact is fixedly connected to the cutting knife and is used for making a motor stop working, so that the cutting knife is stopped from cutting a bottle mouth of a plastic bottle, and accordingly, the cutting dimension is controlled. When the next plastic bottle is cut, a rotary shaft is turned, and the rotaryshaft pulls a spring seat and a sliding block to move through a second steel wire rope, so that the fixing rod is made to move towards the interior of a compression frame, and then the cutting knifeis moved to a cutting point to begin the next cutting process. The plastic product leftover material cutting device can control the cutting dimension.

Description

technical field [0001] The invention relates to the technical field of plastic products, in particular to a device for cutting excess plastic products with controllable cutting size. Background technique [0002] Blow molding technology is a rapidly developing plastic processing method. The tubular plastic parison obtained by extrusion or injection molding of thermoplastic resin is placed in the split mold while it is hot (or heated to a softened state), and compressed air is injected into the parison immediately after the mold is closed to blow the plastic parison. It swells and clings to the inner wall of the mold, and after cooling and demoulding, various hollow products can be obtained. When blow molding a product, the manufactured product will have flash. First, the flash must be removed, and then the process bottle mouth must be processed. Therefore, it is generally necessary to install a flash removal device on the blow molding machine. After the product is removed, ...

AI Technical Summary

Problems solved by technology

When blow molding a product, the manufactured product will have flash. First, the flash must be removed, and then the process bottle mouth must be processed. Therefore, it is generally necessary to install a flash removal device on the blow molding machine. After the product is removed, the mouth is manually trimmed , the efficiency of manually operating the cutter is low, and the precision is not high, which cannot meet the requirements of some products, and it is easy to cause liquid leakage when the product is packaged.

The existing trimming equipment is cut along the radial direction of the bottle mouth, which cannot guarantee the same steps reserved for the bottle mouth, and cannot guarantee the sealing performance in the subsequent packaging process

[0003] The publication number is CN203357758U, which discloses a cutting table for excess material of plastic products. , the cutting table can achieve the effect of cutting plastic bottles, but due to the simple structure of the control device, the sizes after cutting are different, which brings a lot of inconvenience to the subsequent production
