Abstract
Description
Technical Field
[0001] This utility model relates to the field of woven bag technology, and in particular to a plastic woven bag cutting machine. Background Technology
[0002] The main raw material for overseas production is polyethylene (PE), while domestic production mainly uses polypropylene (PP). Polyethylene is odorless and non-toxic, with excellent low-temperature resistance and good chemical stability; polypropylene is usually a translucent colorless solid, odorless and non-toxic, with good heat resistance, and its products can be sterilized with steam. It is also the lightest general-purpose plastic. Cutting woven bags is a common manual operation, often used to transform a whole roll or a whole woven bag into the required length (such as making storage bags, waterproof sheets, temporary coverings, etc.). Woven bags need to be cut during the production process. After cutting, one end of the woven bag is sewn together. However, when using current cutting equipment, relying solely on a blade to cut the woven bag can cause the woven threads at the edge of the cut bag to come loose, affecting its use. Furthermore, single-blade cutting often requires secondary cutting, reducing efficiency. Utility Model Content
[0003] The purpose of this invention is to address the aforementioned problems and shortcomings by proposing a plastic woven bag cutting machine.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: A plastic woven bag cutting machine includes a support platform. One end of the top outer wall of the support platform has a roll unwinding groove, and a cutting assembly is provided at the center of the top outer wall of the support platform. Conveying assemblies are installed on both ends of the top outer wall of the support platform at the cutting assembly. The cutting assembly includes a protective shell installed on the top outer wall of the support platform, a lifting groove opened at the center of the bottom outer wall of the protective shell, mounting seats installed at both ends of the top of the protective shell, and hydraulic cylinders installed in the mounting seats. The conveying assembly includes a support frame installed on the top outer wall of the support platform, an electric push rod installed at the center of the top of the support frame, and a drive frame installed on the bottom outer wall of the electric push rod.
[0005] Furthermore, a blade is installed on the bottom outer wall of the hydraulic cylinder, and a mounting hole is opened on the bottom outer wall of the blade, in which a heating wire is fixedly placed.
[0006] Furthermore, the top outer wall of the support platform is embedded with a force-bearing strip at the bottom of the blade, and the outer wall of the blade is slidably connected to the inner wall of the lifting groove.
[0007] Furthermore, a conveying roller is rotatably connected between the drive frames, and a conveying motor is installed on the outer wall of one end of the drive frame, with the output shaft of the conveying motor connected to one end of the conveying shaft.
[0008] Furthermore, the outer walls at both ends of the support frame are provided with transmission holes, and the conveying motor is slidably connected to the inner wall of the transmission hole.
[0009] Furthermore, the support platform is rotatably connected to a fixed shaft at the unwinding groove, and an unwinding motor is installed on one side of the outer wall of the support platform. The output shaft of the unwinding motor is connected to one end of the fixed shaft, and a feeding groove is opened at the other end of the top outer wall of the support platform.
