Description

Technical Field

[0001] This application relates to the technical field of material cutting and processing, and in particular to cutting edge tooling. Background Technology

[0002] Currently, edge trimming is a crucial process in packaging bag production, ensuring product appearance quality and sealing performance. The quality of edge trimming directly impacts the overall quality of the packaging bag and significantly influences the product's market competitiveness. With the continuous development of the packaging industry, the requirements for packaging bag edge trimming are becoming increasingly stringent. Traditional edge trimming methods are no longer sufficient to meet the demands of modern production. Therefore, developing efficient and precise edge trimming technology has become an inevitable trend in the industry. In recent years, with the growing demand for flexible packaging, the market's need for low-cost, high-efficiency, and simple cutting devices has become increasingly prominent.

[0003] In existing technologies, the following methods are commonly used to trim the edges of packaging bags: mechanical cutters use cylinders to drive the blades in linear motion to complete the cutting. Their structure is relatively simple and they are used in some situations where high precision is not required; rotary circular blade sets use opposing rotating circular blades to achieve continuous cutting, which can make the cut relatively flat and are widely used in some scenarios where the cut quality is required; heat sealing and cutting integrated machines combine heating elements and cutting functions and are suitable for trimming packaging bags of composite film materials.

[0004] However, existing technologies have significant drawbacks: mechanical cutters generate high impact force, easily causing bag deformation and affecting product quality; rotary blade assemblies require precise adjustment of the blade spacing and are unsuitable for thick materials, limiting their application range; heat-sealing and cutting machines consume high energy and pose a risk of edge contamination. Therefore, there is an urgent need for a simple and easy-to-operate packaging bag edge trimming device that can accurately trim the edges of packaging bags without the need for complex power mechanisms, significantly reducing equipment costs and maintenance difficulty. Utility Model Content

[0005] In order to overcome the above problems, this application provides a cutting tool.

[0006] The edge trimming fixture provided in this application adopts the following technical solution: The edge trimming fixture includes an edge trimming handle, a blade holder, and a cutting blade. The edge trimming handle is horizontally positioned and includes an upper body and a lower body. The upper and lower bodies are detachably connected, forming a horizontal channel for packaging bags to pass through. Mounting recesses are provided on the sides of both the upper and lower bodies. The blade holder is located in the mounting recess and is slidably connected to the upper body.

[0012] Optionally, multiple contact blocks of varying heights are fixed on the upper conveyor belt, with the multiple contact blocks spaced apart along the length of the upper conveyor belt.

[0013] By adopting the above technical solution, multiple contact blocks of different heights and fixedly spaced along the length of the upper conveyor belt can better adapt to packaging bags of different thicknesses and shapes, enhance the conveying stability of the packaging bags, improve the smoothness of the cutting process, and reduce the adhesion between the packaging bags and the upper and lower conveyor belts.
