Description

Technical Field

[0001] This utility model relates to the field of polyethylene film processing technology, and in particular to a slitting machine for polyethylene film processing. Background Technology

[0002] PE film, or polyethylene film, refers to film produced from PE granules. It is a thermoplastic plastic film polymerized from ethylene monomers, possessing advantages such as flexibility, chemical resistance, and low cost. It is widely used in packaging, agriculture, construction, and other fields. The processing of polyethylene film requires slitting, necessitating a slitting machine. This slitting machine is a core piece of equipment for precisely slitting wide polyethylene films produced by blow molding and casting into narrow finished films, directly determining the dimensional accuracy and edge quality of the finished film.

[0003] To address this, patent CN222647285U discloses a polyethylene film processing and slitting mechanism. Support rods are installed between fixed blocks, and connecting plates are installed at both ends of the inner wall of the cutting box, with positioning plates between the connecting plates. This polyethylene film processing and slitting mechanism uses an electric telescopic rod to adjust the height of the compaction rollers to compact the polyethylene film before and after slitting, preventing the polyethylene film from dragging or overlapping due to excessive tension during unwinding and rewinding. Simultaneously, the second electric telescopic rod, using the connecting plates and positioning plates, drives the cross hinges for horizontal and vertical stretching. The spacing of the cutters at the bottom of the cross hinges is adjusted, allowing the rewinding roller to slit the polyethylene film within the cutting box. The ability to adjust the cutter spacing according to slitting requirements effectively improves the flexibility and usability of the device.

[0004] The aforementioned polyethylene film processing and slitting mechanism is designed to adjust the spacing of the cutters according to slitting requirements, effectively improving the flexibility and performance of the device. However, when cutting polyethylene film, the film may rise or shift during tension adjustment, causing the film to not adhere tightly to the groove on the mounting frame during cutting, resulting in cutting errors. Utility Model Content

[0005] The purpose of this invention is to provide a slitting machine for polyethylene film processing, which solves the problem that existing slitting machines for polyethylene film processing are difficult to limit the position of the film.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a slitting machine for polyethylene film processing, comprising a housing;

[0007] A workbench is installed on the top of the box, and brackets are installed on both sides of the top of the workbench. A winding wheel is installed on the top of the brackets, and a rotary motor is installed on one end of the winding wheel.

[0008] The top of the box is provided with a groove, a mounting bracket is installed on the top of the box, a hydraulic rod is installed on the top of the mounting bracket, a blade is installed on the bottom of the hydraulic rod, and a groove is provided on the top of the mounting bracket.

[0009] Limiting structures are installed on both sides of the mounting frame, and the limiting structures include mounting blocks installed on both sides of the mounting frame, with mounting grooves provided inside the mounting blocks.

[0010] In use, the cutting position of the blade can be adjusted by moving the mechanism. The polyethylene film can be wound around the screw winding wheel on both sides. The rotating motor can drive the winding wheel to rotate, and the rotation of the winding wheel can drive the film to move and be wound up. The hydraulic rod can drive the blade to rise and fall. When the blade falls, it can cut the film.

[0011] Furthermore, a moving mechanism is installed inside the worktable, and the moving mechanism includes a moving groove installed inside the worktable, a screw installed inside the moving groove, a servo motor installed on one side of the screw, and a moving block installed on the outside of the screw. The moving mechanism can adjust the position of the blade.

[0012] Furthermore, guide rods extend through both ends of the movable block, and the guide rods are symmetrically distributed about the central axis of the movable block, so that the guide rods can guide the movable block.

[0013] Furthermore, adjustment structures are installed on both sides of the top of the workbench, and the adjustment structures include a first telescopic rod installed on the top of the workbench, a second telescopic rod installed at the top of the first telescopic rod, a fixing screw installed on one side of the second telescopic rod, and a guide wheel installed at the top of the second telescopic rod. The adjustment structures can adjust the tension of the film.

[0014] Furthermore, the first telescopic rod has a sliding groove inside, and the bottom end of the second telescopic rod has a slider. The first telescopic rod and the second telescopic rod form a sliding structure, and the second telescopic rod can slide inside the first telescopic rod.

[0015] Furthermore, a limiting plate is installed inside the mounting groove. A rotating wheel is provided at the bottom end of the limiting plate, and positioning rods are installed on both sides of the top end of the limiting plate. A threaded rod is installed at the top end of the limiting plate, and a rotating block is installed at the top end of the threaded rod. The limiting structure can limit the film.

[0016] Furthermore, the outer side wall of the threaded rod is uniformly provided with external threads, and the inner side wall of the mounting block is uniformly provided with internal threads that cooperate with the external threads. The threaded rod and the mounting block are threadedly connected, and the rotation of the threaded rod can drive the limit plate to rise and fall.

[0017] The slitting machine for polyethylene film processing provided by this utility model has the following advantages: during use, the film can be limited by the limiting structure, the cutting position of the blade can be adjusted by the moving mechanism, and the tension of the film can be adjusted by the adjusting structure.

[0018] By installing mounting blocks on both sides of the mounting frame, the film to be cut can pass through the mounting groove inside the mounting block. Twisting the rotating block can drive the threaded rod to rotate, and the rotation of the threaded rod will drive the bottom limiting plate to rise and fall. The rising and falling of the limiting plate can press the film at the bottom, limiting and guiding the film to prevent the film from deviating. At the same time, it can limit the height of the film during cutting. The bottom of the limiting plate is equipped with a rotating wheel, so that when the film moves, the wheel can rotate without affecting the movement of the film. This achieves the purpose of facilitating the limiting of the film in the slitting machine used for polyethylene film processing.

[0019] By installing a first telescopic rod at the top of the workbench, and the first and second telescopic rods forming a sliding structure, the height of the top guide wheel can be adjusted by sliding the second telescopic rod. The second telescopic rod can be fixed by tightening the fixing screw. In use, the film can pass through the guide wheel. By adjusting the height of the guide wheel, the height of the film passing through can be adjusted, thus adjusting the tension of the film and making it easier to cut. This achieves the purpose of making it easier to adjust the film tension in a slitting machine used for polyethylene film processing. Attached Figure Description
