Description

Technical Field

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

[0002] Polyester film (also known as PET film) is a high-molecular-weight plastic film made primarily of polyethylene terephthalate (PET). It possesses characteristics such as high transparency, a wide temperature resistance range, and high chemical stability, and is widely used in various industries including food, pharmaceuticals, and electronics. Polyester film requires slitting during processing, necessitating the use of specialized slitting equipment.

[0003] Chinese utility model patent CN210735775U discloses a film slitting machine. This device, through a cleaning unit, uses cleaning brushes to clean both the top and bottom sides of the film simultaneously, removing impurities adhering to the incoming film and improving film quality. Regarding the aforementioned technology, the inventors believe the following drawbacks exist:

[0004] In actual use, the cleaning brush bristles tend to accumulate dust and impurities after prolonged use. In addition, the existing device lacks an integrated structure to clean the bristles, which reduces the dust removal effect of the cleaning brush on the film. Therefore, we provide a slitting device for polyester film processing. Utility Model Content

[0005] To address the problem of difficulty in removing dust and impurities adhering to brush bristles in the aforementioned background technology, this utility model provides a slitting device for polyester film processing.

[0006] This utility model is achieved using the following technical solution: a slitting device for polyester film processing, comprising a frame and a dust removal component. The inner side of the frame is provided with a mounting base, and a take-up roller is rotatably connected to the mounting base via a rotating shaft. A top plate is fixedly connected to the frame, and an electric push rod is fixedly connected to the top of the top plate. A connecting plate is fixedly connected to the telescopic end of the electric push rod, and cutters are fixedly connected at equal intervals to the bottom of the connecting plate. A brush is provided below the top plate.

[0007] The dust removal assembly includes a slide rod 1 fixedly connected to the lower inner side of the frame. Two sets of sliders are symmetrically slidably connected to the outside of the slide rod 1. The sliders are hinged to the mounting base via a connecting rod 1. Springs are sleeved on both sides of the slide rod 1. Two sets of guide grooves are symmetrically opened on the frame. Guide blocks are slidably connected inside the guide grooves. A connecting shaft is rotatably connected to the guide block, and the connecting shaft is fixedly connected to a rotating shaft on the same side. A motor is fixedly connected to the outside of one of the guide blocks, and the rotor end of the motor is coaxially fixedly connected to the connecting shaft. Two sets of slide rods 2 are symmetrically fixedly connected to the bottom of the top plate. The same sliding plate is slidably connected to the outside of the two sets of slide rods 2, and the sliding plate is fixedly connected to the brush. The sliding plate and the guide block are hinged to a connecting rod 2 via a hinge.

[0008] As a further improvement to the above scheme, two sets of tensioning rollers are symmetrically rotatably connected to the bottom of the top plate.

[0009] As a further improvement to the above solution, a U-shaped groove is provided on the connecting shaft and the rotating shaft is located inside the U-shaped groove. Both the connecting shaft and the rotating shaft are provided with screw holes, and the connecting shaft and the rotating shaft on the same side are threaded together by the same bolt.

[0010] As a further improvement to the above solution, the two ends of the spring are fixedly connected to the frame and the slider, respectively.

[0011] As a further improvement to the above solution, a placement rack is fixedly connected to the bottom of the top plate, and a collection box is provided on the placement rack.

[0012] As a further improvement to the above solution, the brush is fixedly connected to the slide plate by a screw.

[0013] As a further improvement to the above solution, the connecting plate is fixedly connected to the telescopic end of the electric push rod by screw two.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model uses a motor to drive a take-up roller to rotate, enabling the winding of slit polyester film. As the amount of film wound increases, the overall mass also increases. Utilizing the sliding engagement between the guide block and the guide groove, the sliding engagement between the slider and the first slide rod, and the hinged engagement between the mounting base and the slider and the first connecting rod, the take-up roller automatically descends and compresses the spring. Furthermore, the hinged engagement between the guide block and the second slide plate and the second slide rod, along with the sliding engagement between the slide plate and the second slide rod, causes the take-up roller to pull the brush to one side as it descends. When the take-up roller is disassembled, the reduced mass and the spring's rebound action cause the brush to automatically reset. During the reset process, the brush bristles vibrate, shaking off attached dust and impurities, thus achieving automatic cleaning of the brush bristles. This design is highly practical.

[0016] 2. This utility model can collect the dust and impurities that are shaken off by the collection box, thereby avoiding dirt and grime in the production environment. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] Example 1:

[0025] Please combine Figure 1-4This embodiment of a polyester film processing slitting device includes a frame 1, an mounting base on the inner side of the frame 1, a winding roller 2 rotatably connected to the mounting base via a rotating shaft, a top plate 3 fixedly connected to the frame 1, an electric push rod 4 fixedly connected to the top of the top plate 3, a connecting plate fixedly connected to the telescopic end of the electric push rod 4, cutters 5 fixedly connected at equal intervals to the bottom of the connecting plate, a brush 6 provided below the top plate 3, and two sets of tensioning rollers 7 symmetrically rotatably connected to the bottom of the top plate 3 to facilitate tensioning of the polyester film and prevent it from loosening during winding.

[0026] A dust removal assembly for cleaning dust adhering to brush bristles includes a slide rod 101 fixedly connected to the lower inner side of a frame 1. Two sets of sliders 102 are symmetrically slidably connected to the outside of the slide rod 101. A connecting rod 103 is hinged between the sliders 102 and the mounting base via a hinge. Springs 104 are fitted on both sides of the slide rod 101, with the two ends of the springs 104 fixedly connected to the frame 1 and the sliders 102, respectively. Two sets of guide grooves are symmetrically opened on the frame 1. Guide blocks 105 are slidably connected inside the guide grooves. A connecting shaft is rotatably connected to the guide block 105 and fixedly connected to a rotating shaft on the same side. A motor is fixedly connected to the outside of one guide block 105, and the rotor end of the motor is coaxially fixedly connected to the connecting shaft. The bottom of the top plate 3 is symmetrical. Two sets of slide rods 106 are fixedly connected. The two sets of slide rods 106 are externally slidably connected to the same slide plate 107, and the slide plate 107 is fixedly connected to the brush 6. The slide plate 107 and the guide block 105 are hinged to a connecting rod 108. A U-shaped groove is opened on the connecting shaft, and the rotating shaft is set inside the U-shaped groove. Both the connecting shaft and the rotating shaft are provided with screw holes. The connecting shaft and the rotating shaft on the same side are threaded together with the same bolt, which facilitates quick disassembly and assembly of the take-up roller 2. A placement frame is fixedly connected to the bottom of the top plate 3. A collection box 109 is set on the placement frame. The collection box 109 can collect the dust and impurities that are shaken off, thereby avoiding dirt in the production environment. The brush 6 is fixedly connected to the slide plate 107 by a screw, which facilitates the disassembly and replacement of the brush 6.

[0027] The implementation principle of the polyester film slitting device in this embodiment is as follows: the electric push rod 4 pushes the cutter 5 on the connecting plate to descend vertically, thereby slitting the polyester film. The motor drives the connecting shaft on one side to rotate, thereby driving the winding roller 2 to rotate and wind up the slit polyester film. The brush 6 can clean the surface of the conveyed polyester film. As the amount of film wound up increases, the overall mass also increases. The sliding fit between the guide block 105 and the guide groove, the sliding fit between the slider 102 and the slide rod 101, and the hinged fit between the mounting base and the slider 102 and the connecting rod 103 make the winding... The take-up roller 2 automatically descends and compresses the spring 104. With the hinged action between the guide block 105, the slide plate 107, and the connecting rod 108, and the sliding action between the slide plate 107 and the sliding rod 106, the take-up roller 2 pulls the brush 6 to one side when it descends. When the take-up roller 2 is disassembled, due to the reduction in weight and the rebound action of the spring 104, the brush 6 automatically resets. During the reset process, the bristles will shake, thereby shaking off the attached dust and impurities, thus achieving the purpose of automatically cleaning the bristles. The collection box 109 can collect the shaken dust and impurities, thereby preventing the production environment from becoming dirty.

[0028] Example 2:

[0029] Based on Example 1, this embodiment is further improved in that the connecting plate is fixedly connected to the telescopic end of the electric push rod 4 by screw 2, which facilitates the replacement of the cutter 5 according to the cutting requirements.
