Description

Technical Field

[0001] This utility model relates to the technical field of POF heat shrink film processing equipment, specifically a POF heat shrink film cutting device. Background Technology

[0002] POF heat shrink film is non-toxic and odorless, and does not produce harmful gases when burned. It has a higher shrinkage rate and better transparency. It is more flexible and not easy to break. It has excellent physical properties and environmental protection characteristics. It is widely used in packaging for food, daily chemicals, pharmaceuticals, electronic products and other fields. After the shrink film is processed, it needs to be cut to facilitate subsequent reprocessing or transportation.

[0003] For example, the utility model patent disclosed in publication number CN220197840U discloses a heat shrink film cutting device, which includes a device base, a support platform on the top of the device base, connecting plates on both sides of the top of the support platform, a horizontal plate between the two connecting plates, and a moving mechanism at the bottom of the horizontal plate. Through the design of the moving mechanism, when cutting heat shrink films of different specifications, the threaded rod is driven by a motor to rotate. The threaded rod is threadedly connected to the slider, thereby causing the slider to move accordingly. A connecting block is provided at the bottom of the slider. Compared with existing heat shrink film cutting devices, this utility model can improve the overall protection, functionality and practicality of the heat shrink film cutting device through design.

[0004] Although the above-mentioned equipment can cut POF heat shrink film, it is not convenient to cut the shrink film at any angle according to the cutting requirements, which reduces the adaptability of the equipment to cutting different POF heat shrink films. Therefore, there is an urgent need for a POF heat shrink film cutting device to solve the above-mentioned problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides an embodiment of a POF heat shrink film cutting device, including a support base 7. Two sets of linear slide rails 3 are provided on the top of the inner end face of the support base 7, and linear sliders 5 are slidably engaged on the lower end faces of both sets of linear slide rails 3. Positioning bases 4 are provided at the bottom of the two sets of linear sliders 5. A servo motor 8 is provided near the side of the rear end face of the support base 7, and a transmission screw 1 is provided at the output end of the servo motor 8. A thin cylinder 6 is fixedly installed at the center of the upper end face of the positioning bracket 4. The thin cylinder 6 is used for positioning and guiding. The directional device 2 is fixedly installed at the output end of the thin cylinder 6, and is used for directional adjustment and cutting.

[0017] like Figure 3 The steering device 2 includes a guide slide 24, with linear slide shafts 23 symmetrically arranged on the upper part of the guide slide 24, and a stepper motor 25 located at the bottom of the side end face of the guide slide 24. A transmission worm gear 21 is provided at the output end of the stepper motor 25, and a cutting device 22 is rotatably engaged at the bottom of the inner end face of the guide slide 24.

[0018] like Figure 4The cutting device 22 includes a transmission worm gear 221. A positioning rotary seat 226 is provided at the center of the lower end face of the transmission worm gear 221. A cutting cutter 223 is rotatably engaged at the center of the inner end face of the positioning rotary seat 226. A driven gear 224 is provided on the side end face of the cutting cutter 223. A reduction motor 222 is provided near the upper part of the side end face of the positioning rotary seat 226. A drive gear 225 is provided at the output end of the reduction motor 222.

[0019] like Figure 3 The transmission worm 21 is meshed with the transmission worm wheel 221, and the transmission lead screw 1 is threadedly connected to the positioning bracket 4. This can not only adjust the angle at which the cutting tool 223 cuts the heat shrink film, but also improve the self-locking stability of the cutting tool 223 when cutting the heat shrink film.

[0020] like Figure 4 The drive gear 225 meshes with the driven gear 224, which can effectively improve the stability of the drive gear 225 driving the cutting tool 223 to rotate through the driven gear 224, and improve the efficiency of subsequent shrink film cutting.

[0021] like Figure 3 The guide slide 24 is slidably engaged with the lower end face of the positioning bracket 4 via the linear slide shaft 23. The linear slide shaft 23 can provide sufficient guiding foundation for the axial displacement of the guide slide 24, thereby improving the stability of the vertical displacement of the guide slide 24.

[0022] Working Principle: Before use, the operator can position the equipment on the external POF heat shrink film conveying module to facilitate subsequent cutting operations on the conveyed heat shrink film. When longitudinally cutting the heat shrink film, the operator can start the stepper motor 25. The stepper motor 25 drives the transmission worm gear 21 to rotate. Simultaneously, the transmission worm gear 21, through meshing with the transmission worm wheel 221, drives the alignment rotary seat 226 to rotate. Then, the positions of the alignment rotary seat 226 and the cutting blade 223 are adjusted to be parallel to the length direction of the heat shrink film. Then, the operation is started... The moving thin cylinder 6 drives the cutting blade 223 to move downward, cutting the shrink film longitudinally. During cutting, the reduction motor 222 drives the driven gear 224 and the cutting blade 223 to rotate through the driving gear 225, thereby cutting the shrink film. If transverse equidistant cutting is required, the operator can reset the cutting blade 223 to a position parallel to the shrink film laterally, and then start the servo motor 8. At this time, the servo motor 8 can reciprocate to drive the cutting blade 223 to cut the shrink film in segments through the threaded connection with the positioning bracket 4.
