Description

Technical Field

[0001] The utility model relates to the technical field of plastic products, in particular to a positioning mechanism for plastic product cutting and processing. Background Technique

[0002] Plastic products are a general term for daily necessities, industrial products, etc. processed mainly with plastics as raw materials. It includes products made by all processes such as injection molding and thermoforming with plastics as raw materials. Plastics are a type of synthetic polymer material with plasticity. During the processing of plastic products, cutting is required. Among them, the "clamp for plastic processing" disclosed in the publication number "CN218193802U" has solved the following problems existing in the use of existing clamps for plastic processing: Since conventional clamps are generally fixed on the outside of plastic pipes, it is inconvenient to process the blocked areas, resulting in various drawbacks that affect the processing work. After further retrieval, it is found that the "clamp for plastic processing" disclosed in the publication number "CN214418597U" has, through specific technical structure settings, effectively solved the problems that existing clamps for plastic processing can only fix one plastic part at a time. Therefore, during the processing process, it is necessary to frequently replace the plastic parts to be processed, thus reducing the processing efficiency of plastic parts, and that existing clamps for plastic processing cannot adjust the height, so it is not convenient for users of different heights to use, etc. However, in actual use, there are still many defects in positioning mechanisms of similar structures. For example, the applicability of existing positioning mechanisms is general, and they cannot be assembled and used according to cutting requirements during use, and it is very easy to cause extrusion damage to plastic products during the clamping and positioning process. Therefore, it is necessary to design a positioning mechanism for plastic product cutting and processing. Content of the Utility Model

On one side of the electric push rod close to the chute, a clamping plate is fixedly connected through a pressure sensor. The bottom of the fixing plate is detachably installed with a base. An inner cavity is opened inside the base. At the rear end of the inner cavity, a motor is installed. The front end of the motor is fixedly connected with a threaded rod.

[0010] Preferably, both sides of the base are fixedly connected with mounting platforms, and mounting bolts are movably installed inside the mounting platforms. The mounting platforms can be used to expand the contact area between the bottom of the base and the external structure during use.
