Description

Technical Field

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

[0002] Packaging film winding equipment is a key piece of equipment in the packaging production line. It is mainly used to neatly and tightly wind the produced plastic film, composite film and other materials into a roll shape for easy subsequent transportation, storage and use. Its design and working principle directly affect the winding quality, production efficiency and material loss.

[0003] Existing patent document CN212126943U discloses a packaging film winding device comprising a base plate, a support frame fixedly mounted on the top of the base plate, a top plate fixedly mounted on the top of the support frame, two symmetrically arranged movable columns slidably connected to the top plate, the top ends of the two movable columns penetrating the top plate and fixedly mounted with the same connecting plate, a first motor fixedly mounted on the bottom of the top plate, and two symmetrically arranged positioning plates fixedly mounted on the bottom of the top plate, the two positioning plates being located on both sides of the two movable columns. This invention is simple to operate and convenient to use, allowing for easy disassembly of the wound packaging film, while also providing tension during winding, making it easy for users to operate.

[0004] Although the device has many beneficial effects, it still has the following problems: When the device is winding, a worker needs to replace the new winding roller. That is, when a winding roller is fully wound, it needs to be unloaded. During this period, the device is in a stopped state. Replacing the winding roller is time-consuming and requires stopping the machine for replacement. At the same time, when the device is winding the packaging film, there may be particulate impurities that are wound together with the packaging film. The particulate impurities wrapped inside the packaging film may cause damage to the packaging film. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] 1. Technical problems to be solved:

[0007] To address the aforementioned issues, such as the need for personnel to replace the take-up rollers during the winding process, i.e., when a take-up roller is fully wound, it needs to be unloaded, during which the device is shut down, the replacement of the take-up rollers is time-consuming and requires machine shutdown, and the possibility that particulate impurities may be wound along with the packaging film during the winding process, potentially damaging the packaging film if these impurities are trapped inside.

[0008] Therefore, the purpose of this utility model is to provide a packaging film winding device. A winding roller can be installed inside the connecting plate. When one winding roller is winding, the opposite winding roller can be disassembled or installed. The installation and removal of the roller does not require stopping the machine. At the same time, a scraper is fixedly connected to the front of the side plate. The scraper can scrape off the particulate impurities adsorbed on the surface of the packaging film. In conjunction with the cleaning block and brush connected to the bottom of the moving block by the combined screw, the particulate impurities are brushed off, preventing particulate impurities from being mixed into the packaging film.

A cleaning block is fixedly connected to the bottom of the combined screw, and a brush is fixedly connected to the bottom of the cleaning block.

[0013] In a preferred embodiment of the packaging film winding device of this utility model, the bottom four corners of the main board are fixedly connected with support feet, and the top four corners of the main board are fixedly connected with support rods, so that the device can be stably placed on the ground by means of the support rods.

[0014] In a preferred embodiment of the packaging film winding device of this utility model, a top plate is fixedly connected to the top of the support rod, and a first fixing plate is fixedly connected to the bottom of the top plate and the top of the main plate. A pressure roller is connected to the side of the first fixing plate through a rotating shaft. The pressure roller can perform simple pressing on the packaging film before it enters the winding roller area and is wound up, thus ensuring the flatness of the packaging film.

[0015] In a preferred embodiment of the packaging film winding device of this utility model, a telescopic rod is fixedly connected to the top of the first side plate, a pressure plate is fixedly connected to the side of the telescopic rod, a positioning screw is threadedly connected to the inside of the pressure plate, and a first guide roller is connected to the side of the telescopic rod through a rotating shaft.

[0018] 3. Beneficial effects:

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This packaging film winding device consists of multiple connecting plates fixedly connected to the outer circumference of the main shaft. A winding roller for winding is installed inside the connecting plates. When installing the winding roller, the mounting block is aligned with the combination slot and inserted to fix one end first. At the same time, the winding roller is aligned, and the rotating shaft block is pressed into the groove by rotating the clamping screw, thereby installing the winding roller. Since multiple connecting plates are connected to the outer circumference of the main shaft, when one winding roller is winding, the other winding rollers can be disassembled and installed without stopping the machine. The installation and disassembly of the winding rollers are also relatively convenient.

[0021] This type of packaging film winding device features a scraper fixedly connected to the front of the side panel. As the packaging film passes through the scraper, the scraper removes particulate impurities adhering to the film. The particulate impurities scraped off the bottom of the film fall directly into the collection trough, while the particulate impurities scraped off the top of the film continue to be driven away by the scraper due to its obstruction. At this point, by applying a left-right pulling force to the movable handle, the particulate impurities continuously driven by the scraper are swept into the collection trough by a brush, preventing the particulate impurities from being wrapped up together.

[0035] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0036] This utility model provides an overall structural schematic diagram of an embodiment of a packaging film winding device, including:

[0037] Please see Figures 1-7 This embodiment of a packaging film winding device includes a main board 1. A first side plate 7 is welded to the side of the main board 1. Two fourth fixing plates 25 are welded to the side of the first side plate 7. A first motor 28 is fixedly connected to the side of the fourth fixing plates 25 by bolts. The output end of the first motor 28 is fixedly connected to a main shaft 29 by a coupling. The first motor 28 is started and its function is set by a button on an external control panel, so that the first motor 28 automatically stops after rotating 90 degrees in a single rotation. This ensures that the winding roller 37 is rotated to the appropriate position each time, facilitating the winding of the packaging film. The main shaft 29 is welded to the surface of the main shaft 29. Multiple connecting plates 31 are provided. A connecting shaft 30 is welded to the side of the main shaft 29. A clamping screw 41 is threadedly connected to the inside of the connecting plate 31. The bottom of the clamping screw 41 is connected to a rotating shaft block 40 via a rotating shaft. The surface of the rotating shaft block can be embedded in a groove 39. The groove 39 is located on the side of the take-up roller 37. By using the clamping screw 41 and the bottom rotating shaft block 40 in conjunction with the groove 39 on the side of the take-up roller 37, the take-up roller 37 can be fixed in place. When rotating, the rotating shaft block 40 can also rotate together and is not easily affected by the clamping screw 41. A baffle 38 is welded to the outer circumference of the take-up roller 37. The baffle 38 prevents misalignment of the packaging film during winding. A combination slot 36 is provided on the side of the winding roller 37, and an installation block 35 is inserted into the combination slot 36. Inserting the installation block 35 into the combination slot 36 beforehand facilitates determining the installation position. A second motor 34 is fixedly connected to the back of the installation block 35 via a coupling. A pad 33 is welded to the bottom of the second motor 34, and a reinforcing plate 32 is welded to the bottom of the pad 33. A connecting plate 31 is welded to the bottom of the reinforcing plate 32. The connection plate 31, the reinforcing plate 32, and the pad... The cooperation of 33 can enhance the stability of the second motor 34 and prevent it from falling off. The first motor 28 is electrically connected to the first distribution box 26 via a connecting wire, and the second motor 34 is electrically connected to the second distribution box 27 via a connecting wire. The first distribution box 26 and the second distribution box 27 are electrically connected to an external control panel via a connecting wire. The second side plate 12 is fixedly connected to the side of the main board 1. The first motor 28 is electrically connected to the first distribution box 27, and the second motor 34 is electrically connected to the second distribution box 27. This can enhance the operational accuracy of the device and prevent power loss from causing a decrease in control effect.

[0038] It is worth noting that, in order to effectively scrape off particulate impurities from the surface of the packaging film, specifically, a side plate 15 is welded to the side of the second side plate 12, a collection groove 42 is formed on the front of the side plate 15, a through groove 16 is formed inside the second side plate 12, a scraper 17 is glued and fixed to the front of the second side plate 12, and a third fixing plate 18 is welded to both sides of the second side plate 12. A sliding groove 19 is formed inside the third fixing plate 18, and a moving block 20 is slidably connected inside the sliding groove 19. A movable handle 21 is welded to the top of the moving block 20, and a combined screw 22 is threadedly connected to the bottom of the moving block 20. A cleaning block 23 is welded to the bottom of the combined screw 22, and a brush 24 is glued and fixed to the bottom of the cleaning block 23. When the packaging film passes through the scraper 17, both sides of the packaging film are scraped by the scraper 17, thereby scraping off the particulate impurities on the surface of the packaging film. The particulate impurities scraped off the top surface of the packaging film will fall directly into the collection tank 42. Due to the presence of the scraper 17, the particulate impurities scraped off the top surface of the packaging film will be continuously blocked by the scraper 17 after being scraped off, and will continue to move on the top surface of the packaging film. When the device is finished winding, the two scrapers 17 will not inspect the packaging film, and the particulate impurities will fall into the collection tank 42 on their own. Alternatively, when the device is not in use, by pulling the movable handle 21 on the top of the moving block 20, a left and right pulling force will be applied to it. At this time, the movable handle 21 will be pulled, and the combined screw 22 connected to the bottom by the thread will be driven. The combined screw 22 will drive the cleaning block 23 and the brush 24 at its bottom to manually clean the particulate impurities that have been continuously scraped off the top surface of the packaging film by the scraper 17, and sweep the particulate impurities into the collection tank 42, thereby preventing particulate impurities from being trapped inside the packaging film.

[0039] Next, in order to stably place the device, specifically, support feet 2 are welded to the four bottom corners of the main board 1, and support rods 3 are welded to the four top corners of the main board 1.

[0040] Meanwhile, in order to ensure the flatness of the packaging film before winding, specifically, a top plate 4 is welded to the top of the support rod 3, and a first fixing plate 5 is welded to the bottom of the top plate 4 and the top of the main plate 1. A pressure roller 6 is connected to the side of the first fixing plate 5 through a rotating shaft.

[0041] Furthermore, in order to accommodate packaging films of various thicknesses, specifically, a telescopic rod 8 is welded to the top of the first side plate 7, a pressing plate 10 is welded to the side of the telescopic rod 8, a positioning screw 9 is threadedly connected inside the pressing plate 10, and a first guide roller 11 is connected to the side of the telescopic rod 8 via a rotating shaft.

[0042] It is worth noting that, in order to easily guide the packaging film after cleaning, specifically, a second fixing plate 13 is fixedly connected to the top of the second side plate 12, and a second guide roller 14 is connected to the side of the second fixing plate 13 via a rotating shaft.

[0043] Finally, to enhance the operational accuracy of the device, specifically, the first motor 28 and the second motor 34 are fixedly connected to the side of the fourth fixing plate 25, and one end of the connecting shaft 30 is connected to the fourth fixing plate 25 via a rotating shaft.

[0044] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0045] Combination Figures 1-7 The packaging film winding device of this embodiment is used in the following specific process:

[0046] 1. When using this type of packaging film winding device, the winding roller 37 needs to be installed on the connecting plate 31 first. First, by unscrewing the clamping screw 41 outward, the distance between the two connection points is increased. After the clamping screw 41 is removed, the mounting slot at one end of the winding roller 37 can be aligned with the mounting block 35 at the output end of the second motor 34 and inserted. This fixes one end of the winding roller 37 first. Then, the winding roller 37 is aligned. At this time, the clamping screw 41 is screwed inward, and the rotating shaft block 40 connected to the bottom of the clamping screw 41 through the rotating shaft is fitted into the groove 39 on the side of the winding roller 37. Thus, the entire take-up roller 37 is installed inside the two connecting plates 31. The take-up roller 37 can be installed inside each connecting plate 31 as described above. When the take-up roller 37 needs to be removed, it can be disassembled by first unscrewing the clamping screw 41 and then pulling out the take-up roller 37. The installation and disassembly of the take-up roller 37 is relatively convenient.

[0047] 2: When one of the take-up rollers 37 of the device completes the take-up operation, the first motor 28 can be operated and controlled to rotate 90 degrees in one go through the button on the control panel outside the device, so as to easily replace the take-up roller 37. At the same time, the original take-up roller 37 can be directly removed by the above method. The process of disassembling the take-up roller 37 does not require stopping the machine, thus speeding up the take-up efficiency.

[0048] 3. Before the device rewinds the packaging film, it is necessary to prevent particulate impurities attached to the surface of the packaging film from being trapped inside. Before rewinding, the packaging film passes through the scraper 17. Under the scraping of the scraper 17, particulate impurities attached to the top and bottom surfaces of the packaging film are scraped off. The particulate impurities on the bottom surface fall directly into the collection tank 42 after being scraped off. The particulate impurities scraped off the top surface are continuously blocked by the scraper 17 after being scraped off and continue to move on the top surface of the packaging film. At this time, the movable block 20 can be pulled to remove the particulate impurities. Hand 21 applies left and right pulling force to drive the combined screw 22 connected to the bottom by threads. The combined screw 22 drives the cleaning block 23 and brush 24 at its bottom to manually clean the particulate impurities that are continuously scraped off by the scraper 17 on the top surface of the packaging film. Alternatively, after the packaging film is rolled up, the particulate impurities lose their adhesion surface and fall directly into the collection box. At the same time, since the scraper 17 is glued and fixed to the front of the side plate 15, it can be forcibly removed when the sharp edge of the scraper 17 loses its scraping effect and replaced with a new scraper 17.

[0049] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
