Technical Field
[0001] This utility model relates to the technical field of POF heat shrink film processing equipment, specifically a POF heat shrink film rewinding machine that can quickly rewind. Background Technology
[0002] POF heat shrink film is a high-performance heat shrink packaging material made of polyolefin as the main raw material through multi-layer co-extrusion and biaxial stretching processes. POF film is soft and tough, resistant to rubbing and tearing, and can effectively protect products from damage during transportation and storage. After the POF heat shrink film is processed, it needs to be wound up by a winding machine to facilitate subsequent transportation and other operations.
[0003] For example, the utility model patent disclosed in publication number CN213923321U discloses a rapid-winding heat shrink film winding machine, which includes a base plate. A vertical plate is welded to the upper surface of the base plate. A main shaft is rotatably connected to the inner side wall of the vertical plate. A third sleeve is fixedly connected to the outer side wall of the main shaft. This utility model removes the second limiting block from the rod body, then pulls the rod body out of the through hole to contact the support plate. The support plate is pulled away from the main shaft, separating the connection between the support plate and the main shaft. Then, the support plate is placed into the second sliding groove, and the winding drum is replaced. After replacement, the support plate is placed between the two fixed plates and fixed, so that it is connected to the main shaft and the winding work is restarted. This facilitates the replacement of the winding drum and improves the stability of the main shaft. The second rotating shaft, in cooperation with the second sleeve, can tension the film being wound, so that the film will not wrinkle abnormally when the winding drum is wound, which is beneficial to the production quality.
[0004] Although the above-mentioned equipment can change the take-up roll of heat shrink film, the speed of guiding and changing the take-up roll of heat shrink film is insufficient, which increases the time for changing the take-up roll of heat shrink film and reduces the efficiency of subsequent heat shrink film winding. Therefore, there is an urgent need for a POF heat shrink film winding machine that can quickly wind up the film to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a POF heat shrink film rewinding machine that can quickly rewind the film, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a POF heat shrink film winding machine capable of rapid winding, comprising a positioning bracket, a reduction motor disposed at the top of the rear end face of the positioning bracket, and a drive gear disposed at the output end of the reduction motor; two sets of linear slide rails disposed near the front of the upper end face of the positioning bracket, and a cylinder bracket disposed at the center of the front end face of the positioning bracket.
[0007] A pen-shaped cylinder, wherein the pen-shaped cylinder is fixedly mounted on the front end face of the cylinder holder;
[0008] A transmission device, which is slidably engaged with the upper part of the positioning bracket via the linear slide rail, is used for docking and transmission;
[0009] The winding device is rotatably engaged at the rear center of the positioning bracket, and the reduction motor drives the winding device to rotate through the drive gear. Four sets of winding drums are equidistantly engaged at the front of the winding device.
[0010] Preferably, the transmission device includes a positioning slide, a linear slider is symmetrically arranged on the lower end face of the positioning slide, and a servo motor is arranged at the rear center of the positioning slide, with an alignment shaft provided at the output end of the servo motor.
[0011] Preferably, the winding device includes a flipping turntable, a driven gear is provided at the center of the rear end face of the flipping turntable, and four sets of alignment turntables are equidistantly engaged at the inner end face of the flipping turntable. A transmission shaft is provided at the center of the front part of the alignment turntable, and a positioning slot is provided at the center of the front end face of the transmission shaft.
[0012] Preferably, the driving gear and the driven gear are meshed together, and the positioning slide is slidably connected to the upper part of the linear slide rail via the linear slider. The sliding limit of the linear slider and the linear slide rail can effectively improve the stability of the sliding displacement of the positioning slide on the upper part of the positioning card seat.
[0013] Preferably, the winding drum is slidably connected to the transmission shaft. The transmission shaft can provide sufficient limiting and guiding foundation for the winding drum, which can facilitate the subsequent rotation of the winding drum to complete the winding operation of the shrink film, and also facilitate the subsequent rapid unloading operation of the winding drum after winding.
[0014] Preferably, the alignment pin is slidably inserted into the transmission pin via the positioning slot. The sliding limit between the alignment pin and the positioning slot facilitates providing sufficient limiting foundation for the external part of the transmission pin, thereby improving the stability of the alignment pin driving the transmission pin to rotate.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] 1. This utility model features a rotary loading and unloading design. The pen-shaped cylinder drives the alignment pin to cyclically insert into the lower positioning slot, facilitating subsequent cyclic loading of the lower transmission pin and winding drum. This effectively improves the efficiency of the equipment in winding shrink film. Simultaneously, during automated material changing of the winding drum, the reduction motor, through the meshing of the drive gear and driven gear, drives the transmission pin and winding drum to rotate 90 degrees. This facilitates subsequent unloading of the winding drum and simultaneous loading of a new set of winding drums, effectively reducing the loading and unloading time and improving the winding efficiency of shrink film.

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0024] Please see Figure 1-5This utility model provides an embodiment of a POF heat shrink film winding machine capable of rapid winding, comprising a positioning bracket 6, a reduction motor 5 disposed at the top of the rear end face of the positioning bracket 6, and a drive gear 9 disposed at the output end of the reduction motor 5, two sets of linear slide rails 7 disposed near the front of the upper end face of the positioning bracket 6, and a cylinder bracket 8 disposed at the center of the front end face of the positioning bracket 6.
[0025] Pen-shaped cylinder 1 is fixedly mounted on the front end face of cylinder holder 8;
[0026] The transmission device 2 is slidably engaged with the upper part of the positioning bracket 6 via the linear slide rail 7. The transmission device 2 is used for docking and transmission.
[0027] The winding device 3 is rotatably engaged at the rear center of the positioning bracket 6, and the reduction motor 5 drives the winding device 3 to rotate through the drive gear 9. Four sets of winding drums 4 are equidistantly engaged at the front of the winding device 3.
[0028] like Figure 3 The transmission device 2 includes a positioning slide 23, a linear slider 22 is symmetrically arranged on the lower end face of the positioning slide 23, and a servo motor 21 is arranged at the rear center of the positioning slide 23. The output end of the servo motor 21 is provided with an alignment shaft 24.
[0029] like Figure 4 and Figure 5 The winding device 3 includes a flipping turntable 34. A driven gear 35 is provided at the center of the rear end face of the flipping turntable 34, and four sets of alignment turntables 33 are equidistantly engaged on the inner end face of the flipping turntable 34. A transmission shaft 32 is provided at the center of the front part of the alignment turntable 33, and a positioning slot 31 is provided at the center of the front end face of the transmission shaft 32.
[0030] like Figure 2 and Figure 3 The driving gear 9 meshes with the driven gear 35, and the positioning slide 23 is slidably connected to the upper part of the linear slide rail 7 through the linear slider 22. The sliding limit of the linear slider 22 and the linear slide rail 7 can effectively improve the stability of the sliding displacement of the positioning slide 23 on the upper part of the positioning card seat 6.
[0031] like Figure 1 The winding drum 4 is slidably connected to the transmission shaft 32. The transmission shaft 32 can provide sufficient limit and guide foundation for the winding drum 4, which can facilitate the subsequent rotation of the winding drum 4 to complete the winding operation of the shrink film, and also facilitate the subsequent quick unloading operation of the winding drum 4 after winding.
[0032] like Figure 3 and Figure 4The alignment pin 24 slides into the transmission pin 32 through the positioning slot 31. The sliding limit between the alignment pin 24 and the positioning slot 31 can provide sufficient limiting basis for the external of the transmission pin 32, thereby improving the stability of the alignment pin 24 driving the transmission pin 32 to rotate.
[0033] Working principle: During the shrink film winding operation, the operator can insert multiple winding drums 4 into the external drive shaft 32 via the external feeding module. After feeding, the pen-shaped cylinder 1 is activated, which drives the transmission device 2 forward, causing the positioning slide 23 to drive the alignment shaft 24 into the positioning slot 31. At the same time, it limits the other side of the winding drum 4. When winding the shrink film, the servo motor 21 drives the drive shaft 32 to rotate via the alignment shaft 24, so that the drive shaft 32 can drive the winding drum 4 to rotate. The drum 4 rotates to wind up the shrink film. After the winding drum 4 finishes winding up the shrink film, if a new set of winding drums 4 needs to be replaced, the pen-shaped cylinder 1 can first drive the transmission device 2 to reset. Then, the reduction motor 5 can be connected to the driven gear 35 through the meshing of the drive gear 9, thereby driving the wound winding drum 4 to rotate 90 degrees, thus completing the positioning with the transmission device 2. At the same time, the wound winding drum 4 can be positioned at the unloading module, which facilitates the unloading operation of the external unloading module on the winding drum 4.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
