Technical Field
[0001] This utility model relates to the field of stretch film winding technology, and more specifically, to a stretch film winding device. Background Technology
[0002] Stretch film generally refers to heat shrink film, which is commonly used in the sale and transportation of various products. Its main function is to stabilize, cover and protect the products. It has high puncture resistance, good shrinkage and certain shrinkage stress. There are many types and a wide range of applications. In the production process of stretch film, winding is an essential step. Therefore, a winding device is proposed for winding stretch film.
[0003] Most existing stretch film winding devices fix the winding roller to the motor. Starting the motor drives the winding roller to rotate, thereby winding the stretch film. However, disassembly requires the use of tools to remove the winding roller in order to take off the stretch film, which is quite troublesome. In addition, existing stretch film winding devices are prone to wrinkles when winding the stretch film, resulting in an unsightly winding shape. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a stretch film winding device. The technical problem to be solved is that the winding roller is difficult to disassemble and the stretch film is prone to wrinkles.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a stretch film winding device, including a fixing plate.
[0006] A connecting plate and a connecting column are fixedly provided on the upper end of one side of the fixed plate. A drive motor is fixedly provided on one side of the connecting plate by a bracket. The output end of the drive motor passes through the inner side of the connecting plate. A rotating rod is fixedly provided on the output end of the drive motor. A mounting column is fixedly provided on the outer surface of the rotating rod. A winding roller is movably provided on the outer surface of the mounting column.
[0007] The inner side of the connecting column is provided with a recycling and disassembly device that can limit the rotation of the winding roller and disassemble the winding roller.
[0008] The recycling and dismantling device includes a rotating motor, which is fixedly mounted on one side of the lower end of the connecting column by a bracket, and a rotating gear is fixedly mounted on the output end of the rotating motor.
[0009] The upper end of the fixed plate is provided with a downward pressure guide device for pressing the stretch film.
[0010] In a preferred embodiment, a threaded rod passes through the inner groove of the connecting column, and a transmission gear is fixedly provided at the lower end of the threaded rod. The transmission gear is located inside another groove on the inner side of the fixing plate, and the transmission gear and the rotating gear are meshed together.
[0011] In a preferred embodiment, a threaded sleeve is threadedly connected to the outer surface of the threaded rod, and a movable plate is fixedly provided on the outer surface of the threaded sleeve. The movable plate is adapted to the inner groove of the connecting column, and a support plate is fixedly provided on the upper end of one side of the movable plate.
[0012] In a preferred embodiment, a plurality of rolling balls are movably disposed inside the groove at the upper end of the support plate. The rolling balls are located at the lower end of the rotating rod. An installation groove is provided on the inner side of the take-up roller, and the installation groove is adapted to the installation column.
[0013] In a preferred embodiment, the pressing guide device includes a fixed frame, which is fixedly mounted on the upper end of a fixed plate. Two sliding rods pass through the inner side of the fixed frame, and limiting blocks are fixedly mounted on the upper ends of the two sliding rods respectively.
[0014] In a preferred embodiment, the lower ends of the two slide bars are fixedly provided with the same mounting frame, and a pressure roller is movably provided inside the mounting frame, with both ends of the pressure roller penetrating through both sides of the inner wall of the mounting frame.
[0015] In a preferred embodiment, two mounting brackets are fixedly provided on the upper end of the fixing plate, and a guide roller is movably provided between the two mounting brackets. The two ends of the guide roller pass through the interior of the two mounting brackets respectively, and a controller is fixedly provided on one side of the connecting column.
[0016] The technical effects and advantages of this utility model.
[0017] This invention utilizes a rotating motor, rotating gear, transmission gear, and threaded rod to drive the moving plate to move up and down. Because the threaded sleeve is threadedly connected to the threaded rod, and the moving plate fits into the groove inside the connecting column, the moving plate can move up and down. The ball bearings inside the support plate reduce friction on the rotating rod. The mounting groove inside the take-up roller fits into the mounting column, ensuring stable rotation of the take-up roller and preventing slippage. When the take-up roller needs to be disassembled, the moving plate is driven downwards, causing the support plate to disengage from the rotating rod, allowing the take-up roller to be pulled out. This reduces the need for additional tools and makes the take-up roller recovery operation more convenient.
[0018] This invention achieves a pressing effect by utilizing the weight of the mounting frame and the lower pressure roller. The stretch film passes through the lower end of the pressure roller, thus pressing the stretch film. When the winding roller winds up the stretch film, it can prevent the stretch film from being torn by excessive tension. The sliding of the slide bar can buffer the pulling of the stretch film, and pressing down on the stretch film can prevent it from becoming loose and wrinkled during winding, thus improving the aesthetics of the stretched film winding.

Detailed Implementation
[0026] 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 skilled in the art of stretch film winding without creative effort are within the protection scope of the present utility model.
[0027] like Figure 1 and 2 As shown, this utility model provides a stretch film winding device, including a fixed plate 1: a connecting plate 4 and a connecting column 6 are fixedly provided on the upper end of one side of the fixed plate 1, a drive motor 10 is fixedly provided on one side of the connecting plate 4 by a bracket, the output end of the drive motor 10 passes through the inner side of the connecting plate 4, a rotating rod 11 is fixedly provided on the output end of the drive motor 10, a mounting column 12 is fixedly provided on the outer surface of the rotating rod 11, a winding roller 8 is movably provided on the outer surface of the mounting column 12, two mounting frames 5 are fixedly provided on the upper end of the fixed plate 1, a guide roller 7 is movably provided between the two mounting frames 5, the two ends of the guide roller 7 pass through the interior of the two mounting frames 5 respectively, and a controller 9 is fixedly provided on one side of the connecting column 6.
[0028] In order to pull out the take-up roller 8, reduce the use of unnecessary tools, and make it easier to retract the take-up roller 8, a take-up disassembly device 2 is provided on the inner side of the connecting column 6 to limit the rotation of the take-up roller 8 and disassemble the take-up roller 8.
[0029] like Figure 3 , 4 As shown in Figure 5, the recycling and dismantling device 2 includes a rotating motor 21, which is fixedly mounted on one side of the lower end of the connecting column 6 via a bracket. A rotating gear 22 is fixedly mounted on the output end of the rotating motor 21. A threaded rod 24 passes through the inner groove of the connecting column 6. A transmission gear 23 is fixedly mounted on the lower end of the threaded rod 24. The transmission gear 23 is located inside another groove on the inner side of the fixed plate 1. The transmission gear 23 and the rotating gear 22 are meshed together. A threaded sleeve 25 is threadedly connected to the outer surface of the threaded rod 24. A movable plate 26 is fixedly mounted on the outer surface of the threaded sleeve 25. The movable plate 26 is adapted to the inner groove of the connecting column 6. A support plate 27 is fixedly mounted on the upper end of one side of the movable plate 26. Multiple rolling balls 28 are movably mounted inside the groove at the upper end of the support plate 27. The rolling balls 28 are located at the lower end of the rotating rod 11 and inside the winding roller 8. An installation groove 29 is provided, which is adapted to the installation column 12. By rotating the motor 21, rotating gear 22, transmission gear 23 and threaded rod 24, the moving plate 26 can be driven to move up and down. Because the threaded sleeve 25 is threadedly connected to the threaded rod 24, and the moving plate 26 is adapted to the groove inside the connecting column 6, the moving plate 26 can move up and down. The ball 28 on the inner side of the support plate 27 can reduce the friction of the rotating rod 11. The installation groove 29 inside the winding roller 8 is adapted to the installation column 12, so that the winding roller 8 can be driven to rotate stably and avoid slippage. When it is necessary to disassemble the winding roller 8, the moving plate 26 is driven to move down, which drives the support plate 27 to disengage from the rotating rod 11, so that the winding roller 8 can be pulled out, reducing the use of extra tools and making the recycling of the winding roller 8 more convenient.
[0030] Furthermore, in order to buffer the stretch film from being stretched and to prevent the stretch film from becoming loose and wrinkled during winding, thus improving the aesthetics of the stretch film winding, a pressing guide device 3 is provided at the upper end of the fixing plate 1 for pressing the stretch film.
[0031] like Figure 6As shown, the pressing guide device 3 includes a fixed frame 31, which is fixedly mounted on the upper end of the fixed plate 1. Two sliding rods 32 pass through the inner side of the fixed frame 31. Limiting blocks 33 are fixedly mounted on the upper ends of the two sliding rods 32 respectively. The same mounting frame 34 is fixedly mounted on the lower ends of the two sliding rods 32. A pressing roller 35 is movably mounted inside the mounting frame 34. The two ends of the pressing roller 35 pass through the inner walls of the mounting frame 34 respectively. The pressing effect is achieved by the weight of the mounting frame 34 and the pressing roller 35, so that the stretch film passes through the lower end of the pressing roller 35 and can be pressed. When the winding roller 8 winds up the stretch film, it can avoid tearing the stretch film due to excessive tension. The sliding of the sliding rods 32 can buffer the stretch film's pull, and pressing down on the stretch film can prevent it from becoming loose and wrinkled during winding, thus improving the aesthetics of the wound stretch film.
[0032] The working principle is as follows: When using this utility model, the stretch film is laid on the guide roller 7 and passed through the lower end of the pressure roller 35, and then fixed to one side of the take-up roller 8. By driving the motor 10, the rotating rod 11 and the mounting column 12 are driven to rotate. By adapting the mounting column 12 to the mounting groove 29, the take-up roller 8 can be driven to rotate stably. When winding the stretch film, the pressure guide device 3 can prevent wrinkles in the stretch film. When it is necessary to retract the take-up roller 8, the take-up disassembly device 2 can be used to easily disassemble the take-up roller 8, reducing the use of unnecessary tools.
[0033] In addition, it is worth noting that the control process of electrical equipment such as drive motor 10 and rotating motor 21 in this utility model is realized by controller 9. Controller 9 is powered by an external power supply, and the specific control circuit structure of controller 9 is a mature existing technology. Therefore, it will not be described in detail in this utility model.
[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
