Description

Technical Field

[0001] The utility model relates to the technical field of cardboard production, in particular to an automatic cardboard die-cutting device. Background Art

[0002] Cardboard die-cutting refers to the process of using a die-cutting device to process cardboard (usually rigid cardboard or thick cardboard). This processing process is similar to a special die-cutting operation, which can cut the cardboard into the required shapes and sizes according to the designed molds or cutters. Cardboard die-cutting is usually used for making products that require rigid cardboard, such as packaging boxes, display boxes, greeting cards, book covers, etc.

[0003] When the existing die-cutting devices are in use, workers usually need to manually feed the cardboard, and after die-cutting, workers also need to manually collect the cut cardboard, which increases the labor cost and the workload of workers. Moreover, due to relying on manual operation, the production speed is limited and the high efficiency of mechanized operation cannot be achieved. Content of the Utility Model

[0004] The purpose of the utility model is to provide an automatic cardboard die-cutting device that can automatically feed and collect materials, reduce the dependence on manual labor, and improve production efficiency.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows.

[0006] An automatic cardboard die-cutting device includes a U-shaped processing table. A first U-shaped mounting plate is installed on the upper surface of the U-shaped processing table. A first electric push rod is installed on the upper surface of the first U-shaped mounting plate. A die-cutting plate is arranged at the end of the telescopic end of the first electric push rod. A die-cutting knife is installed on the lower surface of the die-cutting plate. A through groove is formed on the surface of the U-shaped processing table, and a die-cutting base is arranged inside the through groove. A feeding plate and a receiving plate are respectively arranged on both sides in the length direction of the U-shaped processing table. A bottom plate is installed between the two side walls of the U-shaped processing table. Lifting mechanisms are arranged on both sides of the upper surface of the bottom plate. The two lifting mechanisms can respectively drive the feeding plate and the receiving plate to vertically lift. A driving mechanism is arranged on the upper side of the bottom plate and is in transmission cooperation with the two lifting mechanisms. A second U-shaped mounting plate is installed on one side of the U-shaped processing table close to the feeding plate. A second electric push rod is installed on the outer surface of the second U-shaped mounting plate. A first push plate is installed at the end of the telescopic end of the second electric push rod.

[0007] It can be seen that by stacking the cardboard on the loading plate, the first push plate pushes the cardboard on the top layer onto the surface of the U-shaped processing table, and the cardboard in the front is pushed forward by the cardboard in the back, thus realizing the conveying of the cardboard. Through the transmission cooperation of the two lifting mechanisms and the driving mechanism, the loading plate and the receiving plate can be lifted and lowered in the opposite direction at the same time. Whenever the cardboard on the top layer is pushed into the U-shaped processing table, the loading plate will rise by the height of the thickness of one cardboard, and at the same time, the receiving plate will drop by the height of the thickness of one cardboard, so that the top layer of the cardboard on the loading plate and the uppermost side of the cardboard on the receiving plate are at the same height as the U-shaped processing table, thus realizing the purpose of automatic loading and unloading, reducing the dependence on manual labor and improving production efficiency.

[0008] Furthermore, the lifting mechanism includes two limit rods installed on the upper surface of the bottom plate. A driving block is slidably installed on the outer surfaces of the two limit rods. A threaded rod is rotatably connected to the upper surface of the bottom plate. The threaded rod passes through the inside of the driving block and is threadedly connected thereto. A through groove is formed on the outer surface of the U-shaped processing table. Connecting blocks are installed on the outer surface of the driving block. The ends of the two connecting blocks are respectively connected to the loading plate and the receiving plate.

[0009] Due to the limiting effect of the two limit rods on the driving block, when the threaded rod rotates, it can drive the driving block to lift vertically along the surface, and drive the loading plate or the receiving plate to lift through the connecting block.

[0010] Furthermore, the driving mechanism includes a rotating shaft rotatably installed between the two side walls of the U-shaped processing table. Two worm gears are installed on the outer surface of the rotating shaft. Worm wheels are installed on the outer surfaces of the two threaded rods, and the worm gears are meshed with the worm wheels. A servo motor is installed on the outer surface of the U-shaped processing table. The output shaft of the servo motor is connected to the rotating shaft.

[0011] Whenever the second electric push rod starts to load materials once, the servo motor will start and drive the rotating shaft to rotate. The rotating shaft drives the two worm gears on its surface to rotate. Since the worm gears are meshed with the worm wheels, the purpose of driving the two threaded rods to rotate simultaneously can be achieved, and the rotating directions of the two threaded rods are opposite, so as to achieve the purpose of driving the loading plate and the receiving plate to lift and lower in the opposite direction.

[0012] Furthermore, a telescopic rod is installed inside the die-cutting knife on the lower surface of the die-cutting plate. A second push plate is installed at the end of the telescopic rod. A spring is sleeved on the outer surface of the telescopic rod. The two ends of the spring are respectively abutted against the die-cutting plate and the second push plate.

[0013] When the first electric push rod drives the die-cutting knife to cut the cardboard, the second push plate will come into contact with the cardboard first. As the die-cutting knife gradually descends, the spring is continuously compressed. The elastic force exerted by the spring on the second push plate can fix the cardboard, improve the cutting quality. And when the die-cutting knife finishes cutting the cardboard, the compressed spring releases the elastic force, which can push the second push plate to extend downward, and then can push away the cut waste, avoiding the waste getting stuck in the die-cutting knife and affecting the cutting.

[0014] Further, a sloping plate is installed on the lower surface of the U-shaped processing table, and the sloping plate is arranged below the through groove.

[0015] When the cut waste is pushed downward by the second push plate, the waste falls on the sloping plate and slides downward along the slope of the sloping plate. Therefore, only by placing a receiving box below the end of the sloping plate can the purpose of waste collection be achieved.

[0016] Further, a connecting plate is installed at the end of the telescopic end of the first electric push rod. The connecting plate and the die-cutting plate are connected by bolts. A placing groove is opened on the inner wall of the through groove, and the die-cutting base is arranged in the placing groove.

[0017] By the way of bolt connection, the die-cutting plate can be replaced. Through the setting of the placing groove, it is convenient to replace the die-cutting base, so that cardboard of different specifications and models can be processed. Description of the Drawings

Detailed implementation mode

[0025] The present utility model will be described in detail below with reference to the accompanying drawings.

[0026] As Figure 1-6 shown, an automatic cardboard die-cutting device includes a U-shaped processing table 100. A first U-shaped mounting plate 101 is installed on the upper surface of the U-shaped processing table 100. A first electric push rod 102 is installed on the upper surface of the first U-shaped mounting plate 101. The end of the telescopic end of the first electric push rod 102 is provided with a die-cutting plate 103. A die-cutting knife 104 is installed on the lower surface of the die-cutting plate 103. A through groove 105 is formed on the surface of the U-shaped processing table 100, and a die-cutting base 106 is arranged inside the through groove 105. A loading plate 107 and an unloading plate 108 are respectively arranged on both sides in the length direction of the U-shaped processing table 100. A bottom plate 112 is installed between the two side walls of the U-shaped processing table 100. Lifting mechanisms 200 are arranged on both sides of the upper surface of the bottom plate 112, and the two lifting mechanisms 200 can respectively drive the loading plate 107 and the unloading plate 108 to vertically lift. A driving mechanism 300 that is in transmission cooperation with the two lifting mechanisms 200 is arranged above the bottom plate 112. A second U-shaped mounting plate 109 is installed on one side of the U-shaped processing table 100 close to the loading plate 107. A second electric push rod 110 is installed on the outer surface of the second U-shaped mounting plate 109. A first push plate 111 is installed at the end of the telescopic end of the second electric push rod 110.

[0027] During use, first, through the transmission cooperation of the lifting mechanism 200 and the driving mechanism 300, the loading plate 107 is lowered to the lowest position, and the receiving plate 108 is raised to the highest position. Then, use a handling tool to place the stacked cardboard on the loading plate 107, making the uppermost layer of the cardboard on the loading plate 107 flush with the surface of the U-shaped processing table 100. Then, start the second electric push rod 110. The second electric push rod 110 drives the first push plate 111 to move, and the uppermost layer of the cardboard can be pushed towards the U-shaped processing table 100. Subsequently, through the transmission cooperation of the lifting mechanism 200 and the driving mechanism 300, the loading plate 107 is raised by the height of one cardboard thickness, and the receiving plate 108 is lowered by the height of one cardboard thickness. The second electric push rod 110 is started again, and the first push plate 111 pushes the uppermost layer of the cardboard towards the U-shaped processing table 100. Subsequently, repeat the raising step, and the cardboard in the front is pushed forward by the cardboard in the back. When the cardboard moves above the die-cutting base 106, the first electric push rod 102 is started, driving the die-cutting plate 103 to descend, so that the die-cutting knife 104 completes the cutting of the cardboard. The waste generated by the cutting can fall downward from the through groove 105. When the processed cardboard is pushed to the end of the U-shaped processing table 100, the receiving plate 108 just descends to be flush with the surface of the U-shaped processing table 100, and then it can be pushed onto the receiving plate 108 by the cardboard in the back to achieve material collection. Then, the receiving plate 108 descends by the height of one cardboard thickness, making the uppermost side of the cardboard on the receiving plate 108 always flush with the surface of the U-shaped processing table 100, thereby achieving the purpose of automatic material collection, and the collected cardboard can be neatly placed without being messy, which is convenient for sorting.

[0028] Specifically, the lifting mechanism 200 includes two limiting rods 201 installed on the upper surface of the bottom plate 112. A driving block 202 is slidably installed on the outer surfaces of the two limiting rods 201. A threaded rod 203 is rotatably connected to the upper surface of the bottom plate 112. The threaded rod 203 penetrates through the interior of the driving block 202 and is threadedly connected thereto. A through groove 204 is formed on the outer surface of the U-shaped processing table 100. Connecting blocks are installed on the outer surface of the driving block 202. The end parts of the two connecting blocks are respectively connected to the loading plate 107 and the receiving plate 108. Due to the limiting effect of the two limiting rods 201 on the driving block 202, when the threaded rod 203 rotates, it can drive the driving block 202 to vertically lift along the surface, and drive the loading plate 107 or the receiving plate 108 through the connecting blocks to achieve the purpose of lifting.

[0029] Specifically, the driving mechanism 300 includes a rotating shaft 301 rotatably installed between the two side walls of the U-shaped processing table 100. Two worm gears 302 are installed on the outer surface of the rotating shaft 301. Worm wheels 303 are installed on the outer surfaces of the two threaded rods 203, and the worm gears 302 are meshed with the worm wheels 303. A servo motor 304 is installed on the outer surface of the U-shaped processing table 100. The output shaft of the servo motor 304 is connected to the rotating shaft 301. Whenever the second electric push rod 110 starts to feed materials once, the servo motor 304 will start and drive the rotating shaft 301 to rotate. The rotating shaft 301 drives the two worm gears 302 on its surface to rotate. Since the worm gears 302 are meshed with the worm wheels 303, the purpose of driving the two threaded rods 203 to rotate simultaneously can be achieved, and the rotating directions of the two threaded rods 203 are opposite, so as to achieve the purpose of driving the feeding plate 107 and the material receiving plate 108 to move up and down in the opposite directions.

[0030] Specifically, a telescopic rod 400 is installed on the lower surface of the die-cutting plate 103 and inside the die-cutting knife 104. A second push plate 401 is installed at the end of the telescopic rod 400. A spring 402 is sleeved on the outer surface of the telescopic rod 400. The two ends of the spring 402 are respectively abutted against the die-cutting plate 103 and the second push plate 401. When the first electric push rod 102 drives the die-cutting knife 104 to cut the cardboard, the second push plate 401 will first contact the cardboard, and as the die-cutting knife 104 gradually descends, the spring 402 is continuously compressed. Through the elastic force exerted by the spring 402 on the second push plate 401, the cardboard can be fixed to improve the cutting quality. And when the die-cutting knife 104 finishes cutting the cardboard, the compressed spring 402 releases the elastic force, which can push the second push plate 401 to extend downward, and then the cut waste can be pushed away to prevent the waste from getting stuck in the die-cutting knife 104 and affecting the cutting.

[0031] Specifically, an inclined plate 500 is installed on the lower surface of the U-shaped processing table 100. The inclined plate 500 is arranged below the through groove 105. When the cut waste is pushed downward by the second push plate 401, the waste falls on the inclined plate 500 and slides downward along the inclined surface of the inclined plate 500. Therefore, only by placing a receiving box below the end of the inclined plate 500 can the purpose of collecting the waste be achieved.

[0032] Specifically, a connecting plate 600 is installed at the end of the telescopic end of the first electric push rod 102. The connecting plate 600 is connected to the die-cutting plate 103 by bolts. A placing groove 601 is opened on the inner wall of the through groove 105. The die-cutting base 106 is arranged in the placing groove 601. By means of bolt connection, the die-cutting plate 103 can be replaced. Through the setting of the placing groove 601, it is convenient to replace the die-cutting base 106, so as to process cardboard of different specifications and models.

[0033] The above is a detailed description of the present utility model in combination with specific embodiments. It cannot be determined that the specific implementation manners of the present utility model are only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model pertains, without departing from the concept of the present utility model, several equivalent substitutions or obvious modifications are made, and the performance or use is the same, and all should be regarded as belonging to the patent protection scope determined by the claims submitted for the present utility model.
