A winding device for heat shrink film production

Abstract

This utility model relates to the field of winding device technology, specifically a winding device for heat shrink film production. By turning on the controller, the controller operates the drive motor, which in turn drives the drive shaft to rotate the rotating shaft. This, in turn, causes one end of the rotating shaft to rotate the crank, which in turn rotates the rotating roller. The rotating roller stretches the material strip, flattens its surface, and eliminates wrinkles. A liquid pump extracts heat-conducting oil from the inner cavity of the guide heat dissipation base through a drain pipe, and then injects the oil back into the base through an inlet pipe. As the oil passes through the radiator, it dissipates heat. When the material strip generates heat through friction as it passes over the guide heat dissipation base, a temperature control component cools the strip.

Technical Field

[0001] This utility model relates to the technical field of winding devices, specifically a winding device for heat shrink film production. Background Technology

[0002] Shrink film is made from high-pressure polyethylene as the base material, with a scientifically formulated ratio of functional additives, and is refined through a one-time blow molding process. This film is widely used in the sales packaging and logistics transportation of various products, and has multiple functions such as stable load-bearing, visual shielding and protective cushioning. The heat shrink film after production needs to be neatly wound up by a special winding device to form a standardized roll shape for subsequent storage, transportation and end-use. When using the winding device for heat shrink film production, there are several issues. When the packaging machine is moving at high speed, ordinary shrink film may wrinkle due to the lag in heat conduction. At the same time, when the heat shrink film is being wound, it is necessary to stretch the heat shrink film because of the wrinkles.

[0003] Therefore, a winding device for heat shrink film production is needed to improve the above problems. Utility Model Content

[0004] To address the problem of wrinkles appearing in ordinary shrink film due to delayed heat conduction when the packaging machine is operating at high speed during the winding process of heat shrink film production, this invention provides a winding device for heat shrink film production to solve the aforementioned problem.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A winding device for producing heat shrink film includes a cabinet, a controller installed on the outer wall of the cabinet, a stretching component installed on the side wall of the cabinet, a temperature control component installed on the outer wall of the cabinet, a positioning bracket installed on the outer wall of the cabinet, and a positioning cylinder rotatably connected to the inner wall of the positioning bracket opposite to it.

[0006] As a preferred embodiment of this utility model, the stretching assembly includes a mounting frame, which is installed on the side wall of the cabinet and located directly below the positioning bracket. A drive motor is installed on the outer wall of the mounting frame, and a fixing sleeve is installed on the inner wall of the mounting frame.

[0007] As a preferred embodiment of this utility model, a rotating shaft is rotatably connected to the inner wall of the fixed sleeve. One end of the rotating shaft is connected to the drive shaft of a drive motor, and a crank is installed at the other end of the rotating shaft. A rotating roller is installed on the inner wall of the crank, wherein the rotating roller is located directly below the positioning cylinder.

[0008] As a preferred embodiment of this utility model, the constant temperature component includes a mounting base and a radiator. The mounting base is installed on the top outer wall of the cabinet, and a limiting shell is installed on the outer wall of the mounting base.

[0009] As a preferred embodiment of this utility model, a guide heat dissipation base is embedded in the inner wall of the limiting shell, wherein the guide heat dissipation base is a hollow structure, a drain pipe is installed on the outer wall of the guide heat dissipation base, and an inlet pipe is installed on one side of the drain pipe and on the outer wall of the guide heat dissipation base.

[0010] As a preferred embodiment of this utility model, the radiator is installed on the top outer wall of the cabinet, one end of the drain pipe is connected to the radiator, a liquid pump is installed on the side wall of the radiator, and the outlet of the liquid pump is connected to the inlet pipe.

[0011] As a preferred embodiment of this utility model, an installation bracket is installed on the outer wall of the cabinet, and a winding motor is installed on the outer wall of the installation bracket. The drive shaft of the winding motor passes through the installation bracket and extends to the outer wall of the installation bracket, where a winding reel is connected. A fixed bracket is installed on the outer wall of the cabinet, and an electrically controlled material tray is rotatably connected to the inner wall of the fixed bracket. A material strip is installed on the inner wall of the electrically controlled material tray, and one end of the material strip passes through a rotating roller, a positioning cylinder, and a guide heat dissipation base in sequence and is connected to the outer wall of the winding reel.

[0012] As a preferred embodiment of this utility model, the controller is electrically connected to a drive motor, a heat sink, a liquid pump, a winding motor, and an electronically controlled material tray via wires.

[0013] Compared with the prior art, this utility model can achieve the stretching and wrinkle elimination of the material strip by setting a stretching component in the winding device used for heat shrink film production. By turning on the controller switch, the controller controls the drive motor to run, which in turn drives the drive shaft to rotate. This causes one end of the shaft to rotate the crank, which in turn drives the rotating roller to rotate. This causes the rotating roller to stretch the material strip, flattening the surface of the material strip and eliminating wrinkles. This solves the problem of stretching the heat shrink film during winding due to wrinkles.

[0014] This invention achieves heat dissipation for the material strip by setting a constant temperature component in the winding device used in heat shrink film production. Heat-conducting oil is injected into the inner cavity of the guide heat dissipation base, and then the controller is turned on, causing the controller to operate the liquid pump. The liquid pump draws out the heat-conducting oil from the inner cavity of the guide heat dissipation base through the drain pipe, and then injects the heat-conducting oil into the guide heat dissipation base through the inlet pipe. As the heat-conducting oil passes through the radiator, the radiator dissipates heat. When the material strip generates heat through friction as it passes over the guide heat dissipation base, the constant temperature component dissipates and cools the material strip. This solves the problem of wrinkles appearing in ordinary shrink film due to delayed heat conduction when the packaging machine is operating at high speeds during heat shrink film winding.

[0019] In this embodiment, specific references Figure 1 , Figure 2 and Figure 3 The stretching assembly 3 includes a mounting bracket 301, which is mounted on the side wall of the cabinet 1 and located directly below the positioning bracket 5. A drive motor 302 is mounted on the outer wall of the mounting bracket 301, and a fixing sleeve 303 is mounted on the inner wall of the mounting bracket 301. A rotating shaft 304 is rotatably connected to the inner wall of the fixing sleeve 303. One end of the rotating shaft 304 is connected to the drive shaft of the drive motor 302, and a crank 305 is mounted on the other end of the rotating shaft 304. A rotating roller 306 is mounted on the inner wall of the crank 305, and the rotating roller 306 is located directly below the positioning cylinder 6.

[0020] In this embodiment, specific references Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The constant temperature component 4 includes a mounting base 401 and a radiator 402. The mounting base 401 is mounted on the top outer wall of the cabinet 1. A limiting housing 403 is mounted on the outer wall of the mounting base 401. A guide heat dissipation base 404 is embedded in the inner wall of the limiting housing 403. The guide heat dissipation base 404 is a hollow structure. A drain pipe 405 is mounted on the outer wall of the guide heat dissipation base 404. An inlet pipe 406 is mounted on one side of the drain pipe 405 and on the outer wall of the guide heat dissipation base 404. The radiator 402 is mounted on the top outer wall of the cabinet 1. One end of the drain pipe 405 is connected to the radiator 402. A liquid pump 407 is mounted on the side wall of the radiator 402. The outlet of the liquid pump 407 is connected to the inlet pipe 406.

[0021] The cabinet 1 has an installation bracket 7 installed on its outer wall. A winding motor 8 is installed on the outer wall of the installation bracket 7. The drive shaft of the winding motor 8 passes through the installation bracket 7 and extends to the outer wall of the installation bracket 7, where a winding reel 9 is connected. A fixed bracket 10 is installed on the outer wall of the cabinet 1. An electrically controlled material tray 11 is rotatably connected to the inner wall of the fixed bracket 10. A material belt 12 is installed on the inner wall of the electrically controlled material tray 11. One end of the material belt 12 passes through the rotating roller 306, the positioning cylinder 6, and the guide heat dissipation base 404 in sequence and is connected to the outer wall of the winding reel 9.

[0022] Based on the above structural features and connection relationships, casters are provided at the bottom corner of cabinet 1, which enable cabinet 1 to move. The controller 2 is electrically connected to the drive motor 302, radiator 402, liquid pump 407, winding motor 8, and electronically controlled material tray 11 via wires, thereby energizing the device. This allows the controller 2 to control the operation of the drive motor 302, radiator 402, liquid pump 407, winding motor 8, and electronically controlled material tray 11.

[0023] In this solution, the winding device for heat shrink film production operates by connecting a drive motor 302, a heat sink 402, a liquid pump 407, a winding motor 8, and an electrically controlled material tray 11 via wires through a controller 2. This electrically connects the controller 2 to these components, enabling the controller 2 to control the operation of the drive motor 302, heat sink 402, liquid pump 407, winding motor 8, and electrically controlled material tray 11. The controller 2 controls the winding motor 8 and the electronically controlled material tray 11 to operate, which will cause the winding motor 8 and the electronically controlled material tray 11 to convey the material strip 12, so that the material strip 12 passes through the rotating roller 306, the positioning cylinder 6 and the guide heat dissipation base 404 in sequence and is connected to the outer wall of the winding tray 9 for winding. By injecting heat-conducting oil into the inner cavity of the guide heat dissipation base 404, and then turning on the switch of the controller 2, the controller 2 controls the liquid pump 407 to operate. The liquid pump 407 will draw out the heat-conducting oil from the inner cavity of the guide heat dissipation base 404 through the drain pipe 405. Then, the liquid pump 407 will inject the heat-conducting oil into the guide heat dissipation base 404 through the inlet pipe 406. When the heat-conducting oil passes through the radiator 402, the radiator 402 will dissipate heat. When the material belt 12 generates heat through friction as it passes through the guide heat dissipation base 404, the constant temperature component 4 will dissipate heat and cool down the material belt 12. This solves the problem of wrinkles appearing in ordinary shrink film due to lag in heat conduction when the packaging machine speed is high during heat shrink film winding. By turning on the switch of controller 2, controller 2 will control drive motor 302 to operate, which will cause drive shaft of drive motor 302 to rotate shaft 304. In turn, one end of shaft 304 will drive crank 305 to rotate, which will cause crank 305 to drive rotating roller 306 to rotate. In turn, rotating roller 306 will stretch material strip 12, which will flatten the surface of material strip 12 and eliminate wrinkles on material strip 12. This solves the problem of stretching heat shrink film when it is wrinkled during heat shrink film winding.
