[0014] The beneficial effects of this utility model are as follows: This utility model provides a fully automatic paper bundling device.

A stack of covers with the cover facing down is placed in the cover hopper for later use. The cover picking mechanism picks up the covers at the bottom of the cover hopper and places them onto the second conveying mechanism. The second conveying mechanism drives the covers to the lower side of the outlet of the paper hopper. The printed paper products are then conveyed stack by stack to one side of the first conveying mechanism. The conveying mechanism transports paper to the inlet of the paper silo. The first unloading mechanism controls the opening and closing of the silo inlet, allowing the paper to fall into the silo or intercepting it. The second unloading mechanism controls the closing of the silo outlet. The paper falling into the silo fills it. The height of the separating plate can be adjusted by a height adjustment mechanism. A horizontal drive cylinder drives the separating plate horizontally into the paper silo, separating the paper and thus distributing it to the designated areas. For thick paper products, the outlet of the paper hopper is opened by the second feeding mechanism, allowing the paper products separated from the hopper to fall onto the cover located on the second conveying mechanism. A plastic belt is supplied to the heat-cutting mechanism via the feeding mechanism. When the paper products pass the heat-cutting mechanism, they pull on the plastic belt, causing the plastic belt to wrap around the paper. The heat-cutting mechanism cuts the plastic belt wrapped around the paper, and the cut ends are welded together. When the bundled paper products are conveyed to the hot-pressing mechanism, the hot-pressing mechanism heats the paper products, and the plastic belt wrapped around the paper products will... The paper is tightened under the heat-pressing action of the heat-pressing mechanism to ensure that it is tightly wrapped. The paper will automatically slide down the guide plate onto the flipping mechanism. The flipping mechanism flips the bundled paper 180° and places it on the third conveying mechanism. The stacking mechanism stacks the bundled paper neatly on the third conveying mechanism, and then the third conveying mechanism outputs the bundled paper. This realizes the automation of paper feeding, paper sorting, cover covering, bundling, tape cutting, heat pressing and tightening, stacking, and output, which can save manpower, reduce labor costs, and improve production efficiency.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure.

[0026] Based on the embodiments described in this disclosure, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this disclosure.

[0027] refer to Figure 1-9 .

[0028] This utility model provides a fully automatic paper bundling device, comprising a frame, on which are arranged a first conveying mechanism 1, a paper hopper 2, a first unloading mechanism 3, a second unloading mechanism 4, a sorting mechanism 5, a second conveying mechanism 6, a guide ramp 7, a cover hopper 8, a cover picking mechanism 9, a tape feeding mechanism 11, a heat cutting mechanism 12, a hot pressing mechanism 13, a flipping mechanism 14, a stacking mechanism 15, and a third conveying mechanism 16; the paper hopper 2 is surrounded by four rectangular right-angle baffles 20 arranged on the frame; the first conveying mechanism 1 is used to convey paper into the inlet of the paper hopper 2; the first unloading mechanism 3 is used to control the opening or closing of the inlet of the paper hopper 2; the second unloading mechanism 4 is used to control the opening or closing of the outlet of the paper hopper 2; the sorting mechanism 5 includes a height adjustment mechanism 50 disposed on the frame and installed on... The height adjustment mechanism 50 includes a horizontal drive cylinder 51 and a distribution plate 52 connected to the horizontal drive cylinder 51, which can move in and out of the paper hopper 2; a second conveying mechanism 6 is used to convey paper products onto the guide inclined plate 7; a cover hopper 8 is formed by four rectangular L-shaped support plates 80 arranged on the frame; a cover picking mechanism 9 is used to pick up and place the covers from the cover hopper 8 onto the second conveying mechanism 6; a belt feeding mechanism 11 is used to supply plastic belts to the hot cutting mechanism 12; the hot cutting mechanism 12 is used to cut the plastic belts and weld the cut ends together; a hot pressing mechanism 13 is used to hot press the plastic belts on the bundled paper products; a flipping mechanism 14 is used to flip the bundled paper products 180° and place them onto the third conveying mechanism 16; and a stacking mechanism 15 is used to neatly stack the paper products that have fallen onto the third conveying mechanism 16.

[0029] Its working principle is as follows: the cross-sectional shape and size of the paper product hopper 2 are set to fit the gap between the paper products to be bundled, and the cross-sectional shape and size of the cover hopper 8 are set to fit the gap between the covers. A stack of covers with the cover facing down is placed in the cover hopper 8 for later use. The cover picking mechanism 9 picks up the covers at the bottom of the cover hopper 8 and places them onto the second conveying mechanism 6. The second conveying mechanism 6 drives the covers to the lower side of the outlet of the paper product hopper 2. The printed paper products are then conveyed one stack at a time to one side of the first conveying mechanism 1. The first conveying mechanism 1 then conveys the paper products to the entrance of the paper product hopper 2. The feeding mechanism 3 controls the opening or closing of the inlet of the paper hopper 2, allowing the paper conveyed to the inlet of the paper hopper 2 to fall into the paper hopper 2 or to be intercepted. The second feeding mechanism 4 controls the closing of the outlet of the paper hopper 2. The paper falling into the paper hopper 2 will fill the paper hopper 2. The height of the dividing plate 52 can be adjusted by the height adjustment mechanism 50. The horizontal drive cylinder 51 drives the dividing plate 52 to move horizontally and enter the paper hopper 2. The dividing plate 52 separates the paper in the paper hopper 2, thereby separating paper of a specified thickness from the paper hopper 2. Mechanism 4 controls the opening of the outlet of the paper hopper 2, allowing the paper products separated from the paper hopper 2 to fall onto the cover located at the second conveying mechanism 6. Plastic tape is supplied to the heat-cutting mechanism 12 via the tape feeding mechanism 11. When the paper products pass through the heat-cutting mechanism 12 driven by the second conveying mechanism 6, the paper products pull on the plastic tape, causing the plastic tape to wrap around the paper products. The heat-cutting mechanism 12 cuts the plastic tape wrapped around the paper products, and the cut ends of the plastic tape are welded together. When the bundled paper products are conveyed to the hot-pressing mechanism 13, the hot-pressing mechanism 13 heats the paper products, and the plastic tape wrapped around the paper products will be removed by the hot-pressing mechanism. The paper is tightened under the hot pressing action of 13, ensuring that the paper is tightly wrapped. The paper will automatically slide down along the guide inclined plate 7 onto the flipping mechanism 14. The flipping mechanism 14 flips the bundled paper by 180° and places it on the third conveying mechanism 16. The stacking mechanism 15 stacks the bundled paper that have fallen on the third conveying mechanism 16 neatly. Then, the third conveying mechanism 16 outputs the bundled paper. This realizes the automation of paper feeding, paper sorting, cover covering, bundling, tape cutting, hot pressing and tightening, stacking, and output. It can save manpower, reduce labor costs, and improve production efficiency.

[0030] Based on the above embodiments, the first conveying mechanism 1 includes a flat-push cylinder 100 mounted on the frame, an X-axis mounting frame 101 slidably connected to the frame along the X-axis direction, a first lifting cylinder 102 mounted on the X-axis mounting frame 101, and a pushing assembly 103. The pushing assembly 103 includes a Z-axis sliding plate 104 slidably connected to the X-axis mounting frame 101 along the Z-axis direction, a connecting arm 105 fixedly connected to the Z-axis sliding plate 104, and pushing plates 106 evenly distributed on the connecting arm 105. The flat-push cylinder 100 is driven to the X-axis mounting frame 101, and the first lifting cylinder 102 is driven to the Z-axis sliding plate 104. A pushing alignment mechanism 107 is provided on one side of the frame. The pushing alignment mechanism 107 includes a pushing alignment drive cylinder 107a mounted on the frame and a push plate 107b driven to the pushing alignment drive cylinder 107a. Specifically, when the horizontal push cylinder 100 is working, it can drive the X-axis mounting frame 101 to move back and forth along the frame, thereby driving the pusher assembly 103 to move back and forth. When the first lifting cylinder 102 is working, it can drive the Z-axis sliding plate 104 to move up and down along the X-axis mounting frame 101, thereby driving the pusher assembly 103 to move up and down. This allows each pusher plate 106 to convey each stack of paper products to the inlet side of the paper hopper 2 in a separated manner, with each stack of paper products located between two pusher plates 106. A guardrail 107c is provided on one side of the frame. When the paper products are conveyed to the front side of the inlet of the paper hopper 2, the paper products are located in front of the pusher plate 107b. By driving the pusher drive cylinder 107a to move the pusher plate 107b towards the guardrail 107c, the paper products are pushed to the inside of the guardrail 107c, ensuring that the paper products are pushed neatly before falling into the paper hopper 2.

The first opening and closing drive mechanism 30 includes two first Y-axis guide rails 300 arranged side by side on the frame, a first rotating connecting plate 301 connected between the two first Y-axis guide rails 300, a first gear 302 rotatably connected to the first rotating connecting plate 301, a first rack 303 slidably connected to the first Y-axis guide rails 300, and a first opening and closing drive cylinder 304 mounted on the frame and drivenly connected to one of the first racks 303.

The second feeding mechanism 4 includes... The device includes a second opening and closing drive mechanism 40 and two opposing second pallet assemblies 41. The second opening and closing drive mechanism 40 includes two second Y-axis guide rails 400 arranged side by side on the frame, a second rotary connecting plate 401 connected between the two second Y-axis guide rails 400, a second gear 402 rotatably connected to the second rotary connecting plate 401, a second rack 403 slidably connected to the second Y-axis guide rails 400, and a second opening and closing drive cylinder 404 mounted on the frame and drivenly connected to one of the second racks 403. The second rack 403 is meshed with the second gear 402. The second pallet assembly 41 includes a second arm plate 410 slidably connected between the two second Y-axis guide rails 400, a second lifting cylinder 411 disposed at one end of the second arm plate 410, and a second pallet 412 drivenly connected to the second lifting cylinder 411. One end of each of the two second racks 403 is fixedly connected to one of the second arm plates 410. When the two second pallets 412 are closed, the outlet of the paper hopper 2 can be closed.Specifically, when the first opening and closing drive cylinder 304 drives the first rack 303 to move back and forth, the first gear 302 will rotate, and the two first racks 303 will move in opposite directions simultaneously, thereby driving the two first pallets 311 to open or close, thus realizing the opening or closing operation of the paper hopper 2 inlet. When the two first pallets 311 are in the open state, the paper conveyed to the paper hopper 2 inlet will automatically fall into the paper hopper 2. When the two first pallets 311 are in the closed state, the paper conveyed to the paper hopper 2 inlet will be automatically closed by the two first pallets 311. One pallet 311 intercepts the paper; when the second opening and closing drive cylinder 404 drives the second rack 403 to move back and forth, the second gear 402 will rotate, and the two second racks 403 will move in opposite directions at the same time, thereby driving the two second pallets 412 to open or close, thus realizing the opening or closing operation of the paper hopper 2 outlet. When the two second pallets 412 are in the open state, the paper at the paper hopper 2 outlet can be discharged from the paper hopper 2 outlet. When the two second pallets 412 are in the closed state, the paper at the paper hopper 2 outlet is intercepted.

[0032] Based on the above embodiments, the height adjustment mechanism 50 includes a longitudinal adjustment seat 500 disposed on the frame, a longitudinal slider 501 slidably connected to the longitudinal adjustment seat 500 along the Z-axis direction, and a longitudinal adjustment screw 502 rotatably connected to the longitudinal adjustment seat 500.

The material distribution plate 52 is supported on the roller 532. Specifically, by rotating the longitudinal adjusting screw 502, the longitudinal slider 501 can be driven to move up and down along the longitudinal adjusting seat 500, thereby adjusting the height of the material distribution plate 52. When the material distribution plate 52 is driven to move back and forth by the horizontal driving cylinder 51, the material distribution plate 52 will drive the roller 532 to rotate. The roller 532 can support the material distribution plate 52, prevent the material distribution plate 52 from tilting, and ensure accurate material distribution.

[0033] Based on the above embodiments, the second conveying mechanism 6 includes a worktable 60 mounted on a frame and two first conveyor belts 61 arranged side-by-side on the worktable 60. Vertical plates 610 are evenly spaced on the surface of each first conveyor belt 61, and a guide plate 7 is connected to one end of the worktable 60. Each stack of paper falls between the two vertical plates 610, separating them.
