[0002] In the production of paper dinner plates (such as cake trays), a small gap is inevitably formed between the upper and lower molds during the pulp molding process. The pulp will seep into the gap, resulting in burrs on the edges of the finished paper dinner plates. Therefore, mechanical deburring is performed after demoulding, which increases the process cost and reduces production efficiency, so further improvement is needed. Summary of the invention

[0003] In order to improve the production efficiency of paper dinner plates, the present application provides an edge burr processing device for producing paper dinner plates.

[0004] The present application provides an edge burr treatment device for paper plate production, which adopts the following technical solution: A device for processing edge burrs for producing paper dinner plates comprises a frame, a slurry box arranged on the frame and having an opening at the top, a lower die seat connected to the bottom wall of the slurry box in a vertical sliding manner, and an upper die seat connected to the frame in a vertical sliding manner and located above the lower die seat, a plurality of forming cavities for forming paper dinner plates are formed between the inner cavities of the lower die seat and the upper die seat, the bottom wall of the forming cavity has water-permeable pores, the slurry box is provided with a spray frame, the spray frame comprises a pair of movable vertical plates respectively located on both sides of the lower die seat / upper die seat and connected to the slurry box in a horizontal sliding direction, a water delivery member fixedly connected between the two movable vertical plates, and a plurality of nozzles connected to the lower end surface of the water delivery member for spraying the plurality of paper dinner plates on the lower die seat, the water delivery member is located between the upper die seat and the lower die seat after demolding, the water delivery member has a water delivery cavity, and the nozzle is connected to the water delivery cavity.

[0005] By adopting the above technical scheme, under normal circumstances, the spray rack is located on one side of the lower mold seat, the lower mold seat first moves down to below the slurry liquid level so that the molding cavity of the lower mold seat is filled with pulp and then rises to above the slurry liquid level, and then the upper mold seat moves down to close the mold and shape it, and excess water is discharged from the water-permeable pores. After the paper plates are batch-formed, the upper mold seat moves up and resets and separates from the lower mold seat. Then, the movable vertical plate slides in the horizontal direction, driving the water delivery part to move between the upper mold seat and the lower mold seat, and the nozzle can spray multiple paper plates on the lower mold seat. The burrs on the edges of the paper plates are wetted and fall off, thereby achieving the effect of simply removing the burrs. There is no need to subsequently use mechanical methods to cut and deburr the paper plates, thereby improving the production efficiency of the paper plates.

[0006] Preferably, the water conveying member is a water conveying plate, a plurality of nozzles are spaced apart and arranged in a row along the length direction of the water conveying plate, at least two rows of nozzles are arranged on the lower end surface of the water conveying plate, and two adjacent rows of nozzles are staggered.

[0007] By adopting the above technical solution, at least two rows of staggered nozzles are arranged on the lower end surface of the water delivery plate. This structure can ensure that during the spraying operation, water can more evenly cover the edges of multiple paper dinner plates on the lower die base, effectively improving the effect of wetting and dropping or falling off the burrs, thereby further improving the efficiency and quality of burr treatment.

[0008] Preferably, the nozzle is rotatably connected to the water delivery member around its own axis, and a first linkage component for driving the nozzle to rotate is provided between the water delivery member and the slurry box.

[0009] By adopting the above technical solution, the nozzle can rotate around its own axis, thereby changing the direction and angle of the water flow during the spraying operation, so that the water flow can more fully cover the burr area on the edge of the paper dinner plate, improving the burr treatment effect. At the same time, the setting of the first linkage component realizes the automation of the nozzle rotation, without the need for an additional power source, reducing the complexity and energy consumption of the equipment, and improving the overall efficiency and reliability of the device.

[0010] Preferably, the first linkage assembly includes a first rack fixedly connected to the slurry box and located below one side of the water delivery member, a first gear coaxially fixedly sleeved on the nozzle, and a second gear rotatably connected to the water delivery member and meshed between the two first gears, and the outermost first gear meshes with the first rack.

[0011] By adopting the above technical solution, when the spray rack moves horizontally, the meshing of the first rack and the first gear can drive the nozzle to rotate around its own axis, thereby changing the water outlet direction of the nozzle. This dynamic adjustment enables the water flow to impact the edge of the paper plate at different angles, thereby enhancing the burr removal effect, while avoiding the cleaning blind area caused by the fixed spray angle, further improving the efficiency and quality of burr treatment.

[0012] Preferably, the slurry box is provided with a liquid supply mechanism for supplying water to the water delivery cavity.

[0013] By adopting the above technical solution, the liquid supply mechanism can provide a stable water supply to the water delivery cavity, ensuring that the nozzle has a continuous and sufficient water flow when spraying the paper dinner plate, thereby improving the effect and efficiency of burr treatment.

[0014] Preferably, the liquid supply mechanism includes a water storage tank fixedly connected to the outer wall of the slurry box, a water supply pipe having one end connected to the water delivery cavity and the other end connected to the water storage tank, and a liquid supply pump arranged on the water supply pipe and fixedly connected to the water storage tank.

[0015] By adopting the above technical solution, the liquid supply mechanism can store water through the water storage tank, and use the liquid supply pump to transport the water in the water storage tank to the water delivery cavity through the water supply pipe, thereby providing a stable spray water source for the nozzle.

[0016] Preferably, the liquid supply mechanism includes a guide box fixedly penetrated at the lower part of the side wall of the slurry box, a piston plate which is slidably and sealably connected to the inner wall of the guide box and divides the inner cavity of the guide box into a first chamber and a second chamber, a first one-way feed pipe fixedly connected to the piston plate and slidably penetrated in the guide box and built into one end of the slurry box, a vertical rod whose lower end is fixedly connected to the first one-way feed pipe and is arranged outside one end of the guide box, and a first one-way discharge pipe fixedly penetrated in the guide box and connected to the first chamber at one end, the upper end of the vertical rod is fixedly connected to the movable vertical plate, the first one-way feed pipe and the first one-way discharge pipe are both provided with one-way valves, the first one-way feed pipe is penetrated in the piston plate so that the first one-way feed pipe is connected to the first chamber, the feed port of the first one-way feed pipe is provided with a filter screen that only allows water to pass through, and the other end of the first one-way discharge pipe is connected to the water delivery cavity.

[0017] By adopting the above technical solution, when the movable vertical plate slides in the horizontal direction, it drives the vertical rod to move, and the piston plate is pushed to slide in the guide box through the first one-way feed pipe, so that the volume of the first chamber and the second chamber changes alternately. When the volume of the first chamber increases, the first one-way feed pipe sucks the water in the slurry box into the first chamber, and the first one-way discharge pipe prevents the water from flowing back; when the volume of the first chamber decreases, the first one-way feed pipe prevents the water from flowing back, and the piston plate presses the water in the first chamber into the water delivery chamber through the first one-way discharge pipe, and sprays it out from the nozzle for spraying. The horizontal reciprocating movement of the movable vertical plate realizes the automatic water supply function without the need for an additional power device. The design of the filter ensures the purity of the water entering the first chamber to prevent the sprayed pulp material from contaminating the plate products.

[0018] Preferably, the inner wall of the slurry box is provided with a spoiler tube immersed in the slurry, the outer peripheral wall of the spoiler tube is provided with a plurality of spoiler holes connected to the inner cavity, the outer peripheral wall of the first one-way discharge pipe and the end face of the guide box are slidingly sealed and connected, the end face of the guide box is fixedly penetrated with a second one-way feed pipe and a second one-way discharge pipe connected to the second chamber, the second one-way feed pipe and the second one-way discharge pipe are both provided with one-way valves, and the second one-way discharge pipe is connected to the spoiler tube.

[0019] By adopting the above technical scheme, when the piston plate slides in the guide box, the volumes of the first chamber and the second chamber change alternately. When the volume of the first chamber increases and the volume of the second chamber decreases, the first chamber stores water through the first one-way feed pipe, and the slurry in the second chamber flows into the spoiler pipe through the second one-way discharge pipe and is sprayed out from the spoiler hole, forming a spoiler effect, effectively improving the slurry fluidity in the slurry box, avoiding sedimentation and stratification of the slurry during long-term standing, ensuring uniform distribution of the slurry, thereby improving the molding quality of the paper plate. When the volume of the first chamber decreases and the volume of the second chamber increases, the piston plate presses the water in the first chamber into the water delivery chamber through the first one-way discharge pipe, and sprays it from the nozzle for spraying operation, and the slurry in the slurry box enters the second chamber through the second one-way feed pipe for storage.

[0020] Preferably, the spoiler tube is rotatably connected to the slurry box, and an expansion box is fixedly penetrated through the side wall of the slurry box. A second linkage assembly for driving the spoiler tube to rotate around its own axis is arranged between the vertical rod and the spoiler tube. The second linkage assembly includes a third gear coaxially fixedly sleeved on one end of the spoiler tube and a second rack fixedly connected to the vertical rod and slidably penetrated through the expansion box, and the third gear is meshed with the second rack.

[0021] By adopting the above technical solution, the second linkage assembly utilizes the horizontal movement of the vertical rod to drive the second rack to slide, thereby driving the third gear to rotate, thereby driving the spoiler tube to rotate around its own axis. The rotating spoiler tube further improves the mixing effect of the slurry, does not require an additional power source, simplifies the structure and reduces costs.

[0022] Preferably, the liquid supply mechanism is provided with two groups, and the two guide boxes are respectively provided with two side walls of the slurry box. When the volume of the first chamber of one of the guide boxes decreases, the volume of the first chamber of the other guide box increases, and the two first unidirectional feed pipes are respectively connected to the two sides of the water conveying member.

[0023] By adopting the above technical solution, when the spray rack moves in the slurry box, the two guide boxes are respectively located on both sides of the slurry box, which can achieve the effect of alternating liquid supply. Specifically, as the movable vertical plate drives the water delivery member to move, the vertical rod moves synchronously, so that when the piston plate in one guide box moves to reduce the volume of the first chamber, the piston plate in the other guide box moves to increase the volume of the first chamber, thereby ensuring the continuity and stability of the liquid supply process and ensuring that the water delivery member always maintains water spraying operation during the horizontal reciprocating movement.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. Under normal conditions, the spray rack is located on one side of the lower die seat. The lower die seat first moves down below the slurry level so that the molding cavity of the lower die seat is filled with pulp and then rises above the slurry level. Then, the upper die seat moves down to close the mold and shape it. Excess water is discharged from the water-permeable pores. After the paper plates are batch-formed, the upper die seat moves up and resets and separates from the lower die seat. Then, the movable vertical plate slides in the horizontal direction, driving the water delivery part to move between the upper die seat and the lower die seat. The nozzle can spray multiple paper plates on the lower die seat. The burrs on the edge of the paper plates are wetted and fall off, achieving the effect of simply removing burrs. There is no need to use mechanical methods to remove burrs on the paper plates, thereby improving the production efficiency of paper plates. 2. The nozzle can rotate around its own axis, thereby changing the direction and angle of the water flow during the spraying process, so that the water flow can more fully cover the burr area on the edge of the paper plate, improving the burr treatment effect. At the same time, the setting of the first linkage component realizes the automation of the nozzle rotation, without the need for an additional power source, reducing the complexity and energy consumption of the equipment, and improving the overall efficiency and reliability of the device; 3. When the movable vertical plate slides in the horizontal direction, it drives the vertical rod to move, and pushes the piston plate to slide in the guide box through the first one-way feed pipe, so that the volume of the first chamber and the second chamber changes alternately. When the volume of the first chamber increases, the first one-way feed pipe sucks the water in the slurry box into the first chamber, and the first one-way discharge pipe prevents the water from flowing back; when the volume of the first chamber decreases, the first one-way feed pipe prevents the water from flowing back, and the piston plate presses the water in the first chamber into the water delivery chamber through the first one-way discharge pipe, and sprays it out from the nozzle for spraying. The horizontal reciprocating movement of the movable vertical plate realizes the automatic water supply function without the need for an additional power device. The design of the filter ensures the purity of the water entering the first chamber to prevent the sprayed pulp material from contaminating the plate products. BRIEF DESCRIPTION OF THE DRAWINGS

A plurality of molding cavities for molding paper dinner plates are formed between the lower mold core 31 and the upper mold core 41, and the bottom wall of the molding cavity has water-permeable pores. The molded paper dinner plates are inverted, that is, the opening of the paper dinner plates faces downward.

[0039] Reference Figure 2 , Figure 4 The upper part of the outer wall of both sides of the slurry box 2 is fixedly connected with a bracket 23, and the bracket 23 is slidably connected with a spray rack 5 along the length direction of the frame 1. The spray rack 5 includes a pair of movable vertical plates 51 respectively located on both sides of the lower mold base 3 / upper mold base 4 and slidably connected to the slurry box 2 along the length direction of the frame 1, a water delivery member fixedly connected between the two movable vertical plates 51, and a plurality of nozzles 53 connected to the lower end surface of the water delivery member to spray multiple paper dinner plates on the lower mold core 31. The water delivery member is located between the upper mold core 41 and the lower mold core 31 after demolding. The water delivery member has a water delivery cavity, and the nozzle 53 is connected to the water delivery cavity.

[0040] Specifically, the water delivery member is a water delivery plate 52, and a plurality of nozzles 53 are spaced apart along the length direction of the water delivery plate 52 to form a row structure. The lower end surface of the water delivery plate 52 is provided with at least two rows of nozzles 53. In this embodiment, two rows of nozzles 53 are provided, and the two adjacent rows of nozzles 53 are staggered, and the nozzles 53 are fixedly connected to the water delivery plate 52. The slurry box 2 is provided with a liquid supply mechanism 6 for supplying water to the water delivery cavity. In this embodiment, the liquid supply mechanism 6 includes a water storage tank 61 fixedly connected to the outer wall of the slurry box 2, a water supply pipe 62 having one end connected to the water delivery cavity and the other end connected to the water storage tank 61, and a liquid supply pump 63 provided on the water supply pipe 62 and fixedly connected to the water storage tank 61. The water supply pipe 62 is a hose.

[0041] The bracket 23 is fixedly connected to the first rodless cylinder 24, the length direction of the first rodless cylinder 24 is parallel to the length direction of the frame 1, and the movable vertical plate 51 is fixedly connected to the slider of the first rodless cylinder 24. The frame 1 is slidably connected to the adsorption mechanism 14 located on one side of the slurry box 2 to adsorb and transport multiple paper dinner plates on the lower mold core 31. The frame 1 drives the adsorption mechanism 14 to slide horizontally as a whole through the second rodless cylinder 15. The adsorption mechanism 14 is a prior art and will not be described in detail here.

[0042] The implementation principle of the edge burr treatment device for paper dinner plate production in the embodiment of the present application is as follows: under normal conditions, the water supply plate 52 is located on one side of the lower die seat 3, the lower die seat 3 and the lower die core 31 are first moved down as a whole to below the slurry liquid level so that the molding cavity of the lower die core 31 is filled with paper pulp and then rises to above the slurry liquid level, the lower die core 31 is always located below the water supply plate 52, then the upper die seat 4 moves down to drive the upper die core 41 to move down for mold closing and shaping, and excess water is discharged from the water-permeable pores. After the batch molding of the paper dinner plates is completed, the upper die seat 4 moves up to separate the upper die core 41 and the lower die core 31 so that the finished paper dinner plates are exposed, and the upper die core 41 is located above the water supply plate 52. Then, the movable vertical plate 51 is moved along the horizontal direction The water supply plate 52 slides and drives the water delivery plate 52 to move between the upper mold core 41 and the lower mold core 31, and the liquid supply pump 63 is started to deliver the water in the water storage tank 61 to the water delivery cavity through the water supply pipe 62 and spray it out from the nozzle 53. The nozzle 53 sprays the multiple paper dinner plates on the lower mold base 3. The burrs on the edges of the paper dinner plates are wetted and fall off, thereby achieving the effect of simply removing the burrs. There is no need to use mechanical methods to cut and deburr the paper dinner plates later, thereby improving the production efficiency of the paper dinner plates. Finally, the horizontal cylinder 12 drives the slurry box 2 to slide to the bottom of the adsorption mechanism 14. After the suction cup of the adsorption mechanism 14 descends to adsorb and demold the multiple paper dinner plates, the adsorption mechanism 14 slides horizontally to transport the paper dinner plates.

[0043] Embodiment 2: The difference from Example 1 is that, referring to Figure 5 , Figure 6 The nozzle 53 is connected to the water conveying plate 52 and rotates around its own axis. A first linkage assembly 7 for driving the nozzle 53 to rotate is arranged between the water conveying member and the slurry box 2. The first linkage assembly 7 includes a first rack 71 fixedly connected to the upper end surface of the slurry box 2 and located below one side of the water conveying plate 52, a first gear 72 coaxially fixedly sleeved on the first row of nozzles 53, and a second gear 73 rotatably connected to the water conveying member and meshed between the two first gears 72. The second gear 73 is coaxially fixedly sleeved on the second row of nozzles 53, and the first gear 72 located on the outermost side is meshed with the first rack 71.

[0044] The implementation principle of Example 2 is as follows: when the spray rack 5 moves horizontally, the meshing of the first rack 71 and the first gear 72 synchronously drives the second gear 73 to rotate, so that the two rows of nozzles 53 can rotate around their own axes, thereby changing the water outlet direction of the nozzles 53, so that the water flow can impact the edge of the paper plate at different angles, thereby enhancing the burr removal effect, and avoiding the cleaning blind area caused by the fixed spray angle, further improving the efficiency and quality of burr treatment.

[0045] Embodiment 3: The difference from Example 1 or 2 is that, referring to Figure 7 , Figure 8 There are two groups of liquid supply mechanisms 6 and they are diagonally distributed along the slurry box 2. Each group of liquid supply mechanisms 6 includes a guide box 64 fixedly penetrated at the lower part of the side wall of the slurry box 2, a piston plate 65 which is slidingly and sealingly connected to the inner wall of the guide box 64 and divides the inner cavity of the guide box 64 into a first chamber 641 and a second chamber 642, a first one-way feed pipe 66 which is fixedly connected to the piston plate 65 and sealingly and slidingly penetrated in the guide box 64 and is built in one end of the slurry box 2, a vertical rod 67 whose lower end is fixedly connected to the first one-way feed pipe 66 and is disposed outside one end of the guide box 64, and a first one-way discharge pipe 68 fixedly penetrated in the guide box 64 and one end of which is connected to the first chamber 641, and the first one-way discharge pipe 68 is a hose.

[0046] The vertical rod 67 is located in the inner cavity of the slurry box 2 and the upper end of the vertical rod 67 is fixedly connected to the movable vertical plate 51. The first one-way feed pipe 66 and the first one-way discharge pipe 68 are both provided with one-way valves. The first one-way feed pipe 66 is fixedly penetrated through the piston plate 65 so that the first one-way feed pipe 66 is connected to the first chamber 641. The feed port of the first one-way feed pipe 66 is provided with a filter screen that only allows water to pass through. The other ends of the two first one-way discharge pipes 68 are respectively connected to the two ends of the water delivery plate 52. When the volume of the first chamber 641 of one of the guide boxes 64 decreases, the volume of the first chamber 641 of the other guide box 64 increases.

[0047] Reference Figure 7 , Figure 8 , Fig. 9 The inner wall of the slurry box 2 is rotatably connected with a spoiler tube 25 immersed in the slurry. Two spoiler tubes 25 are correspondingly provided and are respectively located on both sides of the lower mold base 3. The outer peripheral wall of the spoiler tube 25 is provided with a plurality of spoiler holes 26 connected to the inner cavity. The end surface of the guide box 64 is fixedly penetrated with a second one-way feed pipe 643 and a second one-way discharge pipe 644 connected to the second chamber 642. The second one-way feed pipe 643 and the second one-way discharge pipe 644 are both provided with a one-way valve. The second one-way discharge pipe 644 is connected to one end of the spoiler tube 25 through a rotating joint, and the second one-way discharge pipe 644 is connected to the spoiler tube 25.

[0048] An expansion box 27 is fixedly provided on the side wall of the slurry box 2, and a second linkage assembly 8 for driving the spoiler tube 25 to rotate around its own axis is provided between the vertical rod 67 and the spoiler tube 25. The second linkage assembly 8 includes a third gear 81 coaxially fixedly sleeved on one end of the spoiler tube 25, a support rod 82 fixedly connected to the outer wall of the lower end of the vertical rod 67, and a second rack 83 fixedly connected to the support rod 82 and slidably provided on the expansion box 27. The third gear 81 is meshed with the second rack 83.

[0049] The implementation principle of Example 3 is as follows: when the movable vertical plate 51 slides in the horizontal direction and drives the vertical rod 67 to move, the piston plate 65 is pushed to slide in the guide box 64 through the first one-way feed pipe 66, so that the volume of the first chamber 641 and the second chamber 642 changes alternately. When the volume of the first chamber 641 increases and the volume of the second chamber 642 decreases, the first one-way feed pipe 66 sucks the water in the slurry box 2 into the first chamber 641, and the slurry in the second chamber 642 flows into the spoiler pipe 25 through the second one-way discharge pipe 644 and is sprayed out from the spoiler hole 26 to disturb the slurry; when the volume of the first chamber 641 decreases and the volume of the second chamber 642 increases, the piston plate 65 presses the water in the first chamber 641 into the water delivery cavity through the first one-way discharge pipe 68, and sprays out from the nozzle 53 for spraying operation, and the slurry in the slurry box 2 enters the second chamber 642 through the second one-way feed pipe 643 for storage. The two guide boxes 64 cooperate to ensure the continuity and stability of the liquid supply process, ensure that the water supply plate 52 always maintains water spraying operation during each movement and can disturb the slurry in the slurry box 2, so as to avoid sedimentation and stratification of the slurry during long-term standing. At the same time, during the sliding of the vertical rod 67, the second rack 83 is driven to slide, thereby driving the third gear 81 to rotate, thereby driving the spoiler tube 25 to rotate around its own axis, and the rotating spoiler tube 25 is used to further enhance the mixing effect of the slurry.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
