Description
Technical Field
[0001] This utility model relates to the field of packaging paper box production technology, specifically a packaging paper box laminating and cutting device with a positioning structure. Background Technology
[0002] During the production process of cardboard boxes, a film needs to be applied to the surface of the cardboard box to improve its wear resistance and water resistance. After the cardboard box is covered with film, a special device is needed to cut off the excess film.
[0003] In existing technology, pulling a handle drives a pressure strip, causing the movable groove to move on a straight column, thereby driving a ceramic blade to cut the excess film on the packaging box. However, due to the lack of a structure to fix the packaging box during the cutting process, the packaging box is prone to shifting, making it impossible to accurately cut the excess film and resulting in poor cutting effect.
[0004] As disclosed in CN222407391U, a packaging carton film-coating positioning and cutting device uses a hydraulic cylinder to drive the pressure plate to move downwards and uses a traction rope to pull the drive gear to rotate. At this time, the two racks move relative to each other and drive the two clamping plates to move relative to each other to clamp and fix the packaging carton on the conveyor belt assembly, thereby preventing the packaging carton from shifting and affecting the cutting effect when cutting the film on the packaging carton.
[0005] However, the device cannot locate the film cutting position on the packaging box during use, which affects the film cutting efficiency of the packaging box.
[0006] Therefore, we urgently need to provide a packaging paper box laminating and cutting device with a positioning structure. Utility Model Content
[0007] The purpose of this invention is to provide a packaging paper box film-cutting device with a positioning structure, so as to solve the problem mentioned in the background art that the film cutting position on the packaging paper box cannot be positioned during use, thus affecting the film cutting efficiency of the packaging paper box.
[0008] To achieve the above objectives, the present invention provides the following technical solution: a packaging paper box laminating and cutting device with a positioning structure, comprising a workbench and a conveyor belt, wherein the conveyor belt is installed on the top of the workbench, and a cutting device is provided on the top of the workbench, the cutting device comprising a positioning mechanism, an adjusting mechanism and a pressing mechanism.
[0009] The positioning mechanism is located on the top of the worktable, the adjustment mechanism is located above the worktable, and the clamping mechanism is located on the left side of the top of the worktable.
[0010] The positioning mechanism includes a support frame, a connecting plate, a positioning plate, a slide rail, a movable plate, a mounting frame, a telescopic component, and a cutting shear. The support frame is fixedly installed on the top right side of the workbench. The connecting plate is slidably connected to the inner wall of the support frame. The positioning plate is fixedly installed at the bottom of the connecting plate. The slide rail is fixedly installed on the front and rear sides of the top of the support frame. The movable plate is slidably connected to the inner walls of the front and rear slide rails. The mounting frame is fixedly installed on the top of the movable plate. The telescopic component is fixedly installed on the top of the mounting frame. The cutting shear is fixedly installed at the bottom of the telescopic component.
[0011] Preferably, the positioning mechanism further includes a rotating block, a first spring, a sliding block, a first magnet, a second spring, a top plate, a connecting rod, a second magnet, a support rod, a mounting block, and a pressure block. The rotating block is rotatably connected to the front and rear ends of the top of the connecting plate. One end of the first spring is fixedly installed on the inner wall of the rotating block. The sliding block is fixedly installed on the other end of the first spring and slidably connected inside the rotating block. The first magnet is fixedly installed at the bottom of the rotating block. The second spring is fixedly installed on the top of the connecting plate between the front and rear rotating blocks. The top plate is fixedly installed on the top of the second spring. One end of the connecting rod is fixedly installed at the bottom of the top plate. The second magnet is fixedly installed on the other end of the connecting rod. The support rod is fixedly installed at the front and rear ends of the cutting shears. The mounting block is fixedly installed at the end of the support rod away from the cutting shears. The pressure block is installed inside the mounting block.
[0012] Preferably, the distance between the positioning plate and the cutting scissors is equal to the width of the packaging box to be cut. After the film-coated packaging box is placed on the conveyor belt, the packaging box is transported by the conveyor belt. When one side of the packaging box contacts the positioning plate, the cutting scissors are pushed down by activating the telescopic component to cut the film on the packaging box.
[0013] Preferably, the upper surface of the sliding block is an inclined surface, the lower surface of the pressure block is an inclined surface, and when the bottom of the positioning plate contacts the conveyor belt, the mounting block is located above the sliding block. Magnets one and two attract each other. When the cutting scissors move downwards to cut the film of the packaging box, the pressure block contacts the inclined surface of the sliding block as the cutting scissors move downwards, thereby pushing the sliding block to compress the spring one into the rotating block. At this time, the cutting scissors can move downwards normally to cut the film. After cutting, as the cutting scissors move upwards, the upper surface of the pressure block contacts the lower surface of the sliding block, thereby... The sliding block and connecting plate move upward along the support frame. At the same time, the connecting plate will drive the positioning plate to move upward. When the positioning plate is higher than the height of the packaging box, the packaging box will continue to move to the right under the action of the conveyor belt. When the top plate contacts the top of the support frame, the top plate pushes the connecting rod to drive the second magnetic block to move downward, so that the second magnetic block separates from the first magnetic block. At this time, the rotating block will rotate upward around the connecting plate. The pressure block cannot push the sliding block to move upward, and under the action of gravity, the connecting plate falls to reset, so that the positioning plate continues to position and intercept the next packaging box to be cut.
[0014] Preferably, the adjustment mechanism includes a fixed block, a first threaded rod, and a second threaded rod. The fixed block is fixedly installed on the top right side of the support frame, the first threaded rod is threaded into the inside of the fixed block, and the second threaded rod is threaded into the inside of the mounting block.
[0015] Preferably, the left end of the threaded rod one is rotatably connected to the moving plate, and the right end of the threaded rod two is rotatably connected to the pressure block. By rotating the threaded rod one and threading it to the fixed block, the moving plate drives the telescopic component one to move left and right along the slide rail, thereby adjusting the distance between the cutter and the positioning plate, and thus enabling the cutting of film on packaging boxes of different sizes. In conjunction with rotating the threaded rod two, the pressure block moves left and right along the mounting block, so that the pressure block can contact the sliding block.
[0016] Preferably, the pressing mechanism includes a gantry frame, a second telescopic component, a connecting frame, and a pressure roller. The gantry frame is fixedly installed on the top left side of the workbench, the second telescopic component is fixedly installed on the top of the gantry frame, the connecting frame is fixedly installed on the bottom of the second telescopic component, and the pressure roller is rotatably connected to the inside of the connecting frame.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. The packaging carton film-coating and cutting device with a positioning structure, by setting a positioning mechanism, conveys the packaging carton through a conveyor belt. When one side of the packaging carton contacts the positioning plate, the cutting blade is pushed down by activating the telescopic component to cut the film on the packaging carton, thereby improving the film-cutting efficiency.
[0019] 2. The packaging carton film-coating and cutting device with a positioning structure, by setting a positioning mechanism, after the film on the packaging carton is cut, the positioning plate automatically moves upward to release the interception of the packaging carton.

[0027] 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.
[0028] Example 1:
[0029] Due to the inability of existing technology to accurately position the film cutting location on the packaging box during use, which affects the film cutting efficiency, please refer to [the relevant documentation / reference needed]. Figures 1-4 This embodiment provides a packaging carton laminating and cutting device with a positioning structure, which can improve film cutting efficiency. The packaging carton laminating and cutting device with a positioning structure includes a worktable 1 and a conveyor belt 2. The conveyor belt 2 is mounted on top of the worktable 1, and a cutting device is provided on top of the worktable 1. The cutting device includes a positioning mechanism, an adjusting mechanism, and a pressing mechanism.
[0030] The positioning mechanism is located on the top of the worktable 1, the adjustment mechanism is located above the worktable 1, and the clamping mechanism is located on the top left side of the worktable 1.
[0031] The positioning mechanism includes a support frame 301, a connecting plate 302, a positioning plate 303, a slide rail 304, a moving plate 305, a mounting frame 306, a telescopic component 307, and a cutting shear 308. The support frame 301 is fixedly installed on the top right side of the workbench 1. The connecting plate 302 is slidably connected to the inner wall of the support frame 301. The positioning plate 303 is fixedly installed at the bottom of the connecting plate 302. The distance between the positioning plate 303 and the cutting shear 308 is equal to the width of the packaging box to be cut. After the laminated packaging box is placed on the conveyor belt 2... The packaging carton is conveyed by the conveyor belt 2. When one side of the packaging carton contacts the positioning plate 303, the cutting scissors 308 are pushed down by the activation of the telescopic component 307 to cut the film on the packaging carton. The slide rail 304 is fixedly installed on the front and rear sides of the top of the support frame 301. The moving plate 305 is slidably connected to the inner wall of the front and rear slide rails 304. The mounting frame 306 is fixedly installed on the top of the moving plate 305. The telescopic component 307 is fixedly installed on the top of the mounting frame 306. The cutting scissors 308 are fixedly installed on the bottom of the telescopic component 307.
[0032] The positioning mechanism also includes a rotating block 401, a first spring 402, a sliding block 403, a first magnet 404, a second spring 405, a top plate 406, a connecting rod 407, a second magnet 408, a support rod 409, a mounting block 410, and a pressure block 411. The rotating block 401 is rotatably connected to the front and rear ends of the top of the connecting plate 302. One end of the first spring 402 is fixedly installed on the inner wall of the rotating block 401. After the sliding block 403 retracts into the rotating block 401, the first spring 402 pushes the sliding block 403 outward to achieve reset. The sliding block 403 is fixedly installed on the other end of the first spring 402 and slidably connected inside the rotating block 401. The first magnet 404 is fixedly installed on the rotating block 401. At the bottom, spring 405 is fixedly installed on the top of connecting plate 302 between the two rotating blocks 401. After magnetic block 404 separates from magnetic block 408, spring 405 pushes the top plate 406 upward, causing connecting rod 407 to move magnetic block 408 upward and attract it to magnetic block 404. Top plate 406 is fixedly installed on the top of spring 405. One end of connecting rod 407 is fixedly installed at the bottom of top plate 406, and magnetic block 408 is fixedly installed at the other end of connecting rod 407. The upper surface of sliding block 403 is inclined, and the lower surface of pressure block 411 is inclined. When the bottom of positioning plate 303 contacts conveyor belt 2, mounting block 410 is located above sliding block 403. 04 and magnetic block 408 attract each other. When the cutting scissors 308 move down to cut the film of the packaging box, as the cutting scissors 308 move down, the pressure block 411 will contact the inclined surface of the sliding block 403, thereby pushing the sliding block 403 to squeeze the spring 402 and retract into the rotating block 401. At this time, the cutting scissors 308 can move down normally to cut the film. After the cutting is completed, as the cutting scissors 308 move up, the upper surface of the pressure block 411 will contact the lower surface of the sliding block 403, thereby driving the sliding block 403 and the connecting plate 302 to move up along the support frame 301. At the same time, the connecting plate 302 will drive the positioning plate 303 to move up. When the positioning plate 303 is higher than the height of the packaging box, under the action of the conveyor belt 2 The packaging box will continue to move to the right. When the top plate 406 contacts the top of the support frame 301, the top plate 406 pushes the connecting rod 407 to move the second magnetic block 408 down, so that the second magnetic block 408 separates from the first magnetic block 404. At this time, the rotating block 401 will rotate upward around the connecting plate 302. The pressure block 411 cannot push the sliding block 403 up, and under the action of gravity, the connecting plate 302 falls back to its original position, so that the positioning plate 303 continues to position and intercept the next packaging box to be cut. The support rod 409 is fixedly installed at both ends of the cutting scissors 308. The mounting block 410 is fixedly installed at the end of the support rod 409 away from the cutting scissors 308. The pressure block 411 is installed inside the mounting block 410.
[0033] To achieve film cutting on packaging boxes of different sizes, the distance between the cutter 308 and the positioning plate 303 needs to be adjusted. Therefore, this device also includes an adjustment mechanism, which includes a fixed block 501, a first threaded rod 502, and a second threaded rod 503. The fixed block 501 is fixedly installed on the top right side of the support frame 301. The first threaded rod 502 is threaded into the fixed block 501, and the second threaded rod 503 is threaded into the mounting block 410. The left end of the first threaded rod 502 rotates with the moving plate 305. The right end of the threaded rod 503 is rotatably connected to the pressure block 411. By rotating the threaded rod 502, it is threadedly connected to the fixed block 501, thereby causing the moving plate 305 to drive the telescopic component 307 to move left and right along the slide rail 304, realizing the distance adjustment between the cutter 308 and the positioning plate 303, thus realizing the cutting of film on packaging boxes of different sizes. In conjunction with rotating the threaded rod 503, the pressure block 411 moves left and right along the mounting block 410, so that the pressure block 411 can contact the sliding block 403.
[0034] Example 2:
[0035] Based on Example 1, please refer to Figures 1-6 To improve the film cutting quality, the film on the packaging carton needs to be pressed tightly. Therefore, this device is also equipped with a pressing mechanism, which includes a gantry frame 601, a telescopic component 602, a connecting frame 603, and a pressure roller 604. The gantry frame 601 is fixedly installed on the top left side of the workbench 1, and the telescopic component 602 is fixedly installed on the top of the gantry frame 601. Both the telescopic component 307 and the telescopic component 602 are hydraulic cylinders, model HSG-100. The connecting frame 603 is fixedly installed at the bottom of the telescopic component 602, and the pressure roller 604 is rotatably connected to the inside of the connecting frame 603.
[0036] In use, after the laminated packaging box is placed on the conveyor belt 2, the packaging box is transported by the conveyor belt 2. Then, the telescopic component 2 602 is activated to push the pressure roller 604 down to contact the surface of the packaging box, pressing the film on the packaging box. When one side of the packaging box contacts the positioning plate 303, the telescopic component 1 307 is activated to push the cutting scissors 308 down. As the cutting scissors 308 moves down, the pressure block 411 will contact the inclined surface of the sliding block 403, thereby pushing the sliding block 403 to squeeze the spring 1 402 into the rotating block 401. At this time, the cutting scissors 308 can move down normally to cut the film. After the cutting is completed, as the cutting scissors 308 moves up, the upper surface of the pressure block 411 will contact the lower surface of the sliding block 403. Magnetic block 1 404 and magnetic block 2 404... Under the attraction of 08, the rotating block 401 cannot rotate, thus causing the sliding block 403 to drive the connecting plate 302 to move upward along the support frame 301. At the same time, the connecting plate 302 will drive the positioning plate 303 to move upward. When the positioning plate 303 is higher than the height of the packaging box, the packaging box will continue to move to the right under the action of the conveyor belt 2. When the top plate 406 contacts the top of the support frame 301, the top plate 406 pushes the connecting rod 407 to drive the magnetic block 408 to move downward, so that the magnetic block 408 separates from the magnetic block 404. At this time, the rotating block 401 can rotate upward around the connecting plate 302. The pressure block 411 cannot push the sliding block 403 to move upward, and under the action of gravity, the connecting plate 302 falls back to its original position, so that the positioning plate 303 continues to position and intercept the next packaging box to be cut.
