Description

Technical Field

[0001] This utility model mainly relates to the technical field of PET film processing equipment, specifically a cutting device for PET film processing. Background Technology

[0002] Cutting is an indispensable step in the production and processing of PET film. Traditional cutting devices are often complex in structure and cumbersome in operation, and their cutting efficiency and accuracy need to be improved. Since the cut PET film lacks restraint and is thin and easy to scatter, it requires special personnel to clean it up in real time. Therefore, there is a need for a PET film processing cutting device that is simple in structure, easy to operate, has high cutting efficiency and accuracy, and can automatically clean up the cut film.

[0003] According to application number CN202020368928.6, the device includes a base, a conveying platform, an upper blade holder, a lifting mechanism, and an upper heating component. The conveying platform is fixed above the base and is used to convey the PET film. The upper blade holder is located above the conveying platform and at the end of the conveying platform. An upper cutter is provided at the bottom of the upper blade holder. The lifting mechanism is used to drive the upper blade holder to move up and down. The upper heating component is used to heat the upper blade holder. This PET film cutting device is used in the cutting process of PET film production. The PET film is conveyed by the conveying platform to the area directly below the upper blade holder. The lifting mechanism drives the upper blade holder to descend, and the upper cutter cuts the PET film.

[0004] The aforementioned document states that by installing an upper heating component inside the upper blade holder, when using a higher-temperature upper cutter to cut PET film, the end face of the cut PET film can be made flatter, thus increasing the pass rate of the finished product from the PET film cutting device. However, the cut PET film is prone to scattering and needs to be cleaned up in real time. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a cutting device for PET film processing to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cutting device for PET film processing includes a guide rail, a mounting frame at the top of one end of the guide rail, a film winding wheel at the middle of the other end of the guide rail, multiple idler rollers rotatably located in the middle of the guide rail, a pressure roller at the top of the idler rollers, a driving component located below the mounting frame, a cutting component located below the driving component, an inclined groove located at the discharge end of the guide rail, and a lifting component located at the bottom of the inclined groove.

[0008] Preferably, the idler roller includes a first motor disposed on one side outside the guide rail and connected to one of the idler rollers at its actuating end, a sprocket disposed on the other side outside the guide rail and connected to the central shaft of the idler roller, and a chain connecting all the sprockets.

[0009] Preferably, the pressure roller includes multiple sets of rectangular frames disposed on both sides of the top of the guide rail, a first threaded rod disposed at the upper and lower ends of the rectangular frame, a threaded sleeve sleeved outside the first threaded rod and connected to both ends of the pressure roller, and a knob disposed at the top of the first threaded rod.

[0010] Preferably, the driving component includes a gear reducer suspended below the mounting frame, a second motor located at the top of the mounting frame and whose actuating end is connected to the input end of the gear reducer, two eccentric wheels located at the two parallel output ends of the gear reducer, a first hinge rod connecting the eccentric wheels, and a second hinge rod located at the other end of the first hinge rod.

[0011] Preferably, the cutting component includes a movable plate fixedly connected to the bottom end of the second hinge rod, two first sliding rods passing through both ends of the movable plate and connecting the guide rail and the mounting bracket, a first cutter located below the movable plate, and a second cutter located below the first cutter.

[0012] Preferably, the inclined groove includes a heating rod disposed on the movable plate behind the first cutter, two sliding sleeves disposed at both ends of the inclined groove, and a second sliding rod disposed at one end of the guide rail and passing through the sliding sleeves.

[0013] Preferably, the lifting component includes two second threaded rods located at both ends below the inclined groove, a threaded worm gear rotatably mounted on the bottom of the guide rail and sleeved outside the second threaded rods, a double-headed worm gear rotatably mounted on both sides of the bottom of the guide rail and meshing with the threaded worm gear, and a third motor located on one side outside the guide rail and whose actuating end is connected to the central shaft of the double-headed worm gear.

[0014] In summary, this technical solution has the following main advantages:

[0015] In this embodiment, the idler rollers are driven to rotate by a motor, and the sprocket and chain transmission mechanism is used to achieve synchronous rotation of multiple idler rollers, ensuring that the PET film is transported smoothly and continuously, improving cutting efficiency. The height of the pressure rollers can be adjusted by a knob to adapt to PET films of different thicknesses, ensuring that the material is flat before cutting and improving cutting accuracy.

[0016] The drive unit uses a gear reducer and a motor to provide power, and the movable plate is driven at high speed through an eccentric wheel and a hinge rod. The first and second cutters simultaneously perform double-sided cutting, which improves the cutting speed and efficiency. The heating rod is located behind the cutter and heats the edges of the cut PET film to thermally bond them together, enhancing the firmness of the cut edges and preventing the PET film from falling off.

[0017] The worm gear is driven by a motor to rotate, which in turn drives the threaded worm wheel and threaded rod to rotate, thereby automatically adjusting the height of the inclined groove. This adapts to the accumulation of PET film of different thicknesses, ensuring that the cut PET film can smoothly slide down and accumulate. The overall structure is compact and reasonable, with fewer parts, reducing manufacturing and maintenance costs. The operation interface is intuitive, and the adjustment of parts is convenient, making it easy for operators to adapt and operate efficiently. Attached Figure Description
