Description

Technical Field

[0001] This utility model relates to the field of winding machine technology, and more specifically, to a winding machine. Background Technology

[0002] After the goods are produced, they need to be wrapped with film to protect them. The film also serves to prevent dust, moisture and keep them clean. The existing film is usually wrapped around the goods using a wrapping machine.

[0003] For example, a pallet wrapping machine disclosed in patent CN221718894U, although using a fixed component structure to clamp and fix the product pallet during use, preventing subsequent packaging from sliding or shifting, and symmetrically fastening the fixing plates to the rotating pallet to prevent them from falling off during use, involves prying the clamping plates to both sides during use, placing the stacked foam end cap pallets on the rotating pallet, and then releasing the clamping plates. The clamping plates, under the elastic action of the return spring, then clamp the pallets, thus securing them. The machine is designed for stable clamping. During clamping, the rubber soft plate on the front end face of the clamping plate ensures a tighter grip, preventing loosening. Furthermore, the softness of the rubber prevents damage to the pallet, ensuring stability and preventing product slippage during subsequent packaging. However, in practical use, after the wrapping film on the fixed frame is wrapped around the goods, the operator needs to manually cut the film between the fixed frame and the goods. This is inconvenient for operators and requires improvement. Utility Model Content

[0004] The purpose of this invention is to provide a winding machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0009] Preferably, the column has a cavity inside, and a groove communicating with the cavity is provided on the outer wall of the column. The fixing plate has a connecting plate with one end passing through the groove and extending into the cavity. The connecting plate inside the cavity has a fixing block.

[0010] The lifting assembly includes a rotatable lead screw located inside the cavity. The lead screw is threaded through the fixed block, and the rotation of the lead screw drives the fixed block to lift and lower, thereby achieving the lifting and lowering of the fixed plate.

[0011] Preferably, the side wall of the movable plate is provided with a groove for inserting the blade, and the side wall of the movable plate is provided with a plurality of bolts for assembling and disassembling the blade.

[0012] Preferably, a horizontal plate is provided on one side wall of the base plate, and a toothed plate is provided on the movable plate with one end overlapping the horizontal plate;

[0013] The drive assembly includes a housing on the horizontal plate, and a rotatable gear that meshes with a rack inside the housing. The rotation of the gear drives the rack to move, thereby moving the moving plate.

[0014] Preferably, the horizontal plate and the bottom plate are provided with interconnected slots, and the lower end face of the moving plate and the rack is provided with a locking block that can be inserted into the corresponding slot.

[0033] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0034] The following is in conjunction with the appendix Figures 1-6 This embodiment will be described in further detail.

[0035] like Figure 1 As shown, a wrapping machine in this embodiment includes a base plate 100, a rotatable tray 110 at one end of the base plate 100, a column 120 at the other end of the base plate 100, a slidable fixing plate 121 on the column 120, a fixing rod 260 for the packaging film 122 to be fitted on the fixing plate 121, and a lifting assembly on the column 120 for lifting the fixing plate 121.

[0036] The base plate 100 is also provided with a sliding movable plate 130, the movable plate 130 is provided with a detachable blade 400, and the base plate 100 is provided with a drive assembly, which is used to drive the movable plate 130 to move.

[0037] The movable plate 130 is provided with a protective plate 300 sleeved on the blade 400. The movable plate 130 is provided with a protective component. The movable plate 130 moves to drive the protective component, so that the protective component drives the protective plate 300 to protect or remove the protection of the blade 400.

[0038] In this embodiment, the goods are placed on the pallet 110, and then one end of the film on the packing film 122 is fixed to the goods. At this time, the pallet 110 drives the goods to rotate, so that the film can wrap around the surface of the goods, thus protecting the goods. When the packing film 122 is wrapping the goods, the lifting component on the column 120 can drive the fixing plate 121 to rise and fall. That is, the fixing plate 121 can drive the packing film 122 on the fixing rod 260 to rise and fall, so that the film can be evenly wrapped around the surface of the goods, thereby avoiding the film from being wrapped in the same position on the goods, which would result in poor protective effect of the packing film 122.

[0039] The fixing rod 260 is fixedly installed on the fixing plate 121. When the packing film 122 is sleeved on the fixing rod 260, the rotation of the goods can pull the packing film 122 to rotate on the fixing rod 260, so that the film on the packing film 122 can be wrapped around the goods.

[0040] When the film is wrapped around the goods, it is necessary to cut the film between the packaging film 122 and the goods. At this time, the moving plate 130 is moved by the drive component, so that the blade 400 on the moving plate 130 can cut the film. Compared with the existing ones, this type of wrapping machine does not require the operator to manually cut the film during actual use, which makes it easier to use.

[0041] The blade 400 is always exposed, making it easy for the blade to cut workers. When the drive component does not drive the moving plate 130 to move, the protective component on the moving plate 130 drives the protective plate 300 to move, so that the blade of the blade 400 is located inside the protective plate 300, thereby preventing the exposed blade from cutting workers.

[0042] When the driving component drives the moving plate 130 to move, the protective component drives the protective plate 300 to move, so that the blade on the blade 400 can pass through the protective plate 300, and the blade passing through the protective plate 300 can cut the film.

[0043] The width of the film is less than the height of the blade 400. When the blade 400 cuts the film, the lifting assembly needs to drive the fixing plate 121 to the bottom position, that is, the packing film 122 on the fixing plate 121 is at the bottom position so that the blade 400 can cut the film.

[0044] In actual use, a support ring 111 is fixedly installed at one end of the base plate 100. The upper end face of the support ring 111 has a groove along its circumference. A protruding ring 250 is fixedly installed on the lower end face of the tray 110 along its circumference. The lower end face of the tray 110 overlaps the upper end face of the support ring 111 and the protruding ring 250 is inserted into the groove, so that the tray 110 can be rotated on the base plate 100. A first motor 160 is also fixedly installed inside the support ring 111. The output shaft of the first motor 160 is connected to the center position of the tray 110, so that the tray 110 can be driven to rotate by the first motor 160.

[0045] like Figure 1-2 As shown, in this embodiment, a cavity 201 is provided inside the column 120, and a groove 202 communicating with the cavity 201 is provided on the outer wall of the column 120. A connecting plate 210 with one end penetrating through the groove 202 and extending into the cavity 201 is provided on the fixing plate 121. A fixing block 211 is provided on the connecting plate 210 inside the cavity 201.

[0046] The lifting assembly includes a rotatable lead screw 220 disposed in the cavity 201. The lead screw 220 is threaded through the fixing block 211. The rotation of the lead screw 220 drives the fixing block 211 to lift and lower, thereby realizing the lifting and lowering of the fixing plate 121.

[0047] In this embodiment, the arrangement of the column 120, cavity 201, slide 202, connecting plate 210, fixing block 211, and lead screw 220 enables the column 120 to be fixedly installed on the base plate 100, one end of the connecting plate 210 to be fixedly connected to the fixing plate 121, and the other end of the connecting plate 210 to be fixedly connected to the fixing block 211 through the slide 202. The slide 202 is vertically arranged and limits the connecting plate 210, that is, the fixing block 211 is limited. The two ends of the lead screw 220 are installed on the side wall of the cavity 201 through bearings. When the lead screw 220 rotates, the lead screw 220 can drive the fixing block 211 to rise and fall. The rise and fall of the fixing block 211 can drive the fixing plate 121 to rise and fall through the connecting plate 210, thereby realizing the raising and lowering of the packing film 122 on the fixing plate 121.

[0048] In actual use, a second motor 240 is fixedly installed on the column 120. The output shaft of the second motor 240 is connected to the lead screw 220, so that the lead screw 220 can be driven to rotate by the second motor 240.

[0049] like Figure 1-4 As shown, in this embodiment, a horizontal plate 140 is provided on one side wall of the base plate 100, and a rack 320 with one end attached to the horizontal plate 140 is provided on the movable plate 130.

[0050] The drive assembly includes a housing 330 disposed on the horizontal plate 140. The housing 330 contains a rotatable gear 340 that meshes with the rack 320. The rotation of the gear 340 drives the rack 320 to move, thereby enabling the moving plate 130 to move.

[0051] In this embodiment, by configuring the horizontal plate 140, rack 320, housing 330, and gear 340, the horizontal plate 140 is fixedly mounted on the base plate 100, the rack 320 is fixedly mounted on the movable plate 130, and the housing 330 is fixedly mounted on the horizontal plate 140. When the gear 340 inside the housing 330 rotates, the gear 340 rotates and drives the rack 320 to move. The movement of the rack 320 can drive the movable plate 130 to move, thereby enabling the blade 400 on the movable plate 130 to cut the film.

[0052] A third motor 341 is fixedly installed on the outer wall of the housing 330. The output shaft of the third motor 341 extends into the housing 330. A gear 340 is fixedly installed on the output shaft of the third motor 341, so that the gear 340 can be driven to rotate by the third motor 341.

[0053] Both the horizontal plate 140 and the base plate 100 have interconnected slots 231. The lower end faces of the moving plate 130 and the rack 320 are fixedly installed with a locking block 321 that is inserted into the corresponding slot 231. The cross sections of the locking block 321 and the slot 231 are T-shaped. By locking the locking block 321 into the slot 231, the moving plate 130 and the rack 320 can be slidably installed on the base plate 100 and the horizontal plate 140. At the same time, the slot 231 limits the locking block 321, making the movement of the moving plate 130 and the rack 320 more stable.

[0054] In actual use, the side wall of the movable plate 130 is provided with a groove for inserting the blade 400. The side wall of the movable plate 130 is provided with multiple bolts 310 for assembling and disassembling the blade 400. One end of the bolt 310 passes through the blade 400 and is threaded into the movable plate 130, so that the blade 400 can be installed on the movable plate 130. When the blade 400 is worn and needs to be replaced, the blade 400 can be removed from the movable plate 130 and replaced by unscrewing the bolt 310.

[0055] like Figure 1-5 As shown, in this embodiment, the two sides of the movable plate 130 extend outward to form movable parts 350, and the two sides of the protective plate 300 extend outward to form protective parts 301. The protective plate 300 is provided with a plurality of round rods 500, one end of which passes through the corresponding movable part 350.

[0056] The protective assembly includes multiple cylindrical bodies 351 disposed on the movable part 350. Each cylindrical body 351 has a cavity 510 for inserting a corresponding round rod 500. Each round rod 500 in the cavity 510 is provided with a round plate 501. A spring 520 is also provided in the cavity 510. The spring 520 is used to move the round plate 501 toward the movable part 350, so as to realize the protection of the blade 400 by the protective plate 300.

[0057] In this embodiment, the arrangement of the moving part 350, the protective part 301, the round rod 500, the cylinder 351, the cavity 510, the round plate 501, and the spring 520 allows the round rod 500 to be fixedly mounted on the protective part 301, the round plate 501 to be fixedly mounted on the round rod 500, and the cylinder 351 to be fixedly mounted on the moving plate 130. When the spring 520 in the cavity 510 pushes the round plate 501 to move towards the moving part 350, the movement of the round plate 501, through the round rod 500, can drive the protective part 301 to move. That is, the protective part 301 moves the protective plate 300 away from the moving plate 130, so that the blade 400 is located inside the protective plate 300, thereby achieving the protection of the blade 400 by the protective plate 300.

[0058] The base plate 100 is fixedly mounted with opposing abutment plates 150, which are used for the corresponding protective parts 301 to abut against. When the moving plate 130 drives the blade 400 to move toward the abutment plate 150, the moving plate 130 also drives the protective plate 300 to move. At this time, the movement of the protective plate 300 pushes the film toward the abutment plate 150. When the protective parts 301 on both sides of the protective plate 300 abut against the corresponding abutment plate 150, the protective plate 300 also abuts the film on the abutment plate 150. At this time, the protective plate 300 cannot move. The drive assembly continues to drive the blade 400 to move through the moving plate 130, so that the blade 400 can extend out from the protective plate 300. The extended blade 400 can cut the film between the two abutment plates 150.

[0059] In actual use, after the blade 400 cuts the film, the drive assembly drives the moving plate 130 to move to the initial position. At this time, under the action of the spring 520, the protective plate 300 also begins to move, so that the blade 400 is once again located inside the protective plate 300 for protection.

[0060] In practical use, the goods are first placed on the pallet 110. Then, one end of the packing film 122 is fixed to the goods. At this time, the pallet 110 is rotated by the first motor 160, allowing the film to wrap around the goods. While the film is being wrapped, the second motor 240 drives the lead screw 220 to rotate, which in turn drives the packing film 122 on the fixed plate 121 to rise and fall, ensuring the film is evenly wrapped around the goods. After wrapping is complete, the third motor 341 drives the gear 340 to rotate, which in turn drives the rack 320 on the moving plate 130. The moving plate 130 moves towards the two abutment plates 150. After the protective plate 300 on the moving plate 130 pushes the film onto the abutment plates 150, the moving plate 130 continues to move, allowing the blade 400 on the moving plate 130 to extend from the protective plate 300 and cut the film. After the film is cut, the third motor 341 drives the gear 340 to rotate, and the gear 340 drives the rack 320 to reset, that is, the moving plate 130 resets. At this time, under the action of the spring 520, the protective plate 300 also begins to move, so that the blade 400 is once again located inside the protective plate 300 for protection.

[0061] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
