Description

Technical Field

[0001] This utility model relates to the field of pulp molding processing technology, specifically to a circumferential cutting device for pulp molding products. Background Technology

[0002] Pulp molding is a three-dimensional papermaking technology. It uses waste paper as raw material and shapes paper products into specific forms using special molds on a molding machine. The production process includes pulping, adsorption molding, drying and setting, etc., and is environmentally friendly; it can be recycled and reused.

[0003] After hot pressing, drying, and shaping, pulp molded products require irregular edge trimming using a trimming device to achieve the desired appearance. However, existing circumferential cutting equipment is not convenient for positioning the pulp molded product during the circumferential cutting process, which leads to displacement of the pulp molded product during cutting and reduces the accuracy of the circumferential cutting. To address these issues, the inventors propose a circumferential cutting device for pulp molded products. Utility Model Content

[0004] To address the problem that circumferential cutting equipment is difficult to position during the circumferential cutting process of pulp molding, which leads to displacement of the pulp molding during cutting and reduces circumferential cutting accuracy, the purpose of this utility model is to provide a circumferential cutting equipment for pulp molding products.

[0005] To solve the above technical problems, this utility model adopts the following technical solution: a ring cutting device for pulp molding products, including a worktable, a rotating disk above the worktable, a pressure plate below the rotating disk, a limiting rod that moves through the rotating disk, a limiting ring fixed at the top of the limiting rod, a fixing ring fixedly sleeved on the outer surface of the limiting rod, a spring fixedly connected between the rotating disk and the fixing ring, a guide ring fixedly fixed at the bottom of the limiting rod, the guide ring slidingly disposed within the pressure plate, a movable groove opened within the pressure plate, the guide ring slidingly disposed within the movable groove, a rolling groove opened within the pressure plate, and a ball bearing rotating within the guide ring, the ball bearing moving within the rolling groove. First, the pulp molding product is placed on the placement plate. By rotating the rotating ring, the lead screw rotates within the groove, causing the movable block to move the mounting base and the cutter head. Simultaneously, the movable block moves the pointer, which, in conjunction with the scale plate, allows observation of the adjusted length. This allows for adjustment of the cutter head distance according to different pulp molding products, thereby enabling precise control of the cutting size of the pulp molding product.

[0006] Then, the first motor is turned on, causing the threaded rod to rotate and the threaded block to drive the moving plate to descend. At the same time, the second motor and the rotating disk descend, allowing the cutter head to contact the pulp molded product. This causes the pressure plate to press the center of the pulp molded product, while the limiting rod slides through the rotating disk, causing the spring to be squeezed between the rotating disk and the fixed ring. This allows the pressure plate to limit the pulp molded product, preventing displacement during cutting and improving the accuracy of the ring cutting. Then, the second motor is turned on, causing the rotating disk to drive the cutter head to rotate. At the same time, the guide ring and the limiting rod slide in the movable groove, causing the ball to roll in the groove. Thus, the pressure plate remains stationary during the cutting process, allowing the excess parts of the pulp molded product to be removed.

[0007] Preferably, a movable block is slidably disposed within the rotating disk, a mounting base is fixedly disposed at the bottom end of the movable block, a cutter head is mounted within the mounting base, a scale plate is fixedly disposed on the top surface of the rotating disk, an extension rod is fixedly disposed on the top surface of the movable block, a pointer is fixedly disposed at the top end of the extension rod, a groove is formed within the rotating disk, the movable block is slidably disposed within the groove, a lead screw is rotatably disposed within the rotating disk, a rotating ring is fixedly disposed at one end of the lead screw, and the movable block is threadedly sleeved on the outer surface of the rotating ring.

[0008] Preferably, a placement plate is fixedly provided on the top surface of the workbench, a fixed frame is fixedly provided on the top surface of the workbench, a movable plate is slidably provided on one side of the fixed frame, a second motor is installed on the bottom surface of the movable plate, the output end of the second motor is fixedly connected to the top surface of the rotating disk, a first motor is installed on the top surface of the fixed frame, a threaded rod is fixedly provided on the output end of the first motor, a threaded block is fixedly provided on one side of the movable plate, and the threaded block is threadedly sleeved on the outer surface of the threaded rod.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. In this utility model, when the rotating disk descends, it causes the pressure plate to press the center of the pulp molded product. At the same time, the limiting rod slides through the rotating disk, causing the spring to be squeezed between the rotating disk and the fixed ring. This allows the pressure plate to limit the pulp molded product, preventing the pulp molded product from shifting during cutting and improving the accuracy of ring cutting.

[0011] 2. In this utility model, by rotating the rotating ring, the movable block drives the mounting base and the cutter head to move. At the same time, the movable block drives the pointer to move, and in conjunction with the scale plate, the length to be adjusted can be observed. Thus, the distance of the cutter head can be adjusted according to different pulp molding products, thereby accurately controlling the cutting size of the pulp molding products.

[0019] 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.

[0020] Example: Figure 1-5As shown, this utility model provides a ring-cutting device for pulp molding products, including a worktable 1, a rotating disk 3 above the worktable 1, a pressure plate 35 below the rotating disk 3, a limiting rod 31 movably passing through the rotating disk 3, a limiting ring 32 fixedly attached to the top of the limiting rod 31, a fixing ring 34 fixedly sleeved on the outer surface of the limiting rod 31, a spring 33 fixedly connected between the rotating disk 3 and the fixing ring 34, a guide ring 36 fixedly attached to the bottom end of the limiting rod 31, the guide ring 36 slidably disposed within the pressure plate 35, a movable groove 351 opened within the pressure plate 35, the guide ring 36 slidably disposed within the movable groove 351, a rolling groove 352 opened within the pressure plate 35, and the guide ring 36 slidably disposed within the rotating disk 3. The device is equipped with ball bearings 37, which move within the groove 352. When the rotating disk 3 descends, it causes the pressure plate 35 to press the center of the pulp molded product. At the same time, the limiting rod 31 slides through the rotating disk 3, causing the spring 33 to be squeezed between the rotating disk 3 and the fixed ring 34. This allows the pressure plate 35 to limit the pulp molded product, preventing displacement during cutting and improving the accuracy of the ring cutting. During cutting, the second motor 25 is turned on, causing the rotating disk 3 to drive the cutter head 44 to rotate. At the same time, the guide ring 36 and the limiting rod 31 slide within the movable groove 351, causing the ball bearings 37 to roll within the groove 352. Thus, the pressure plate 35 remains stationary during the cutting process.

[0021] A movable block 42 is slidably provided inside the rotating disk 3. A mounting base 43 is fixedly provided at the bottom end of the movable block 42. A cutter head 44 is installed inside the mounting base 43. A scale plate 47 is fixedly provided on the top surface of the rotating disk 3. An extension rod 45 is fixedly provided on the top surface of the movable block 42. A pointer 46 is fixedly provided at the top end of the extension rod 45. A groove 301 is provided inside the rotating disk 3. The movable block 42 is slidably provided in the groove 301. A lead screw 4 is rotatably provided inside the rotating disk 3. A rotating ring 41 is fixedly provided at one end of the lead screw 4. The movable block 42 is threaded onto the outer surface of the rotating ring 41.

[0022] By adopting the above technical solution, the lead screw 4 rotates within the groove 301 by rotating the rotating ring 41, and the movable block 42 drives the mounting base 43 and the cutter head 44 to move. At the same time, the movable block 42 drives the pointer 46 to move, and in conjunction with the scale plate 47, observes the adjusted length. Thus, the distance of the cutter head 44 can be adjusted according to different pulp molding products, thereby accurately controlling the cutting size of the pulp molding products. The cutter head 44 is installed in the mounting base 43 by bolts.

[0023] A placement plate 11 is fixedly provided on the top surface of the workbench 1. A fixed frame 2 is fixedly provided on the top surface of the workbench 1. A movable plate 24 is slidably provided on one side of the fixed frame 2. A second motor 25 is installed on the bottom surface of the movable plate 24. The output end of the second motor 25 is fixedly connected to the top surface of the rotating disk 3. A first motor 21 is installed on the top surface of the fixed frame 2. A threaded rod 22 is fixedly provided on the output end of the first motor 21. A threaded block 23 is fixedly provided on one side of the movable plate 24. The threaded block 23 is threadedly sleeved on the outer surface of the threaded rod 22.

[0024] By adopting the above technical solution, the pulp molded product is placed on the placement plate 11. By turning on the first motor 21, the threaded rod 22 is rotated, and the threaded block 23 drives the moving plate 24 to descend. At the same time, the second motor 25 and the rotating disk 3 descend, so that the cutter head 44 can contact the pulp molded product. Then, the second motor 25 is turned on, causing the rotating disk 3 to rotate, and driving the cutter head 44 to rotate, thereby cutting off the excess parts of the edge of the pulp molded product.

[0025] Working principle: First, place the pulp molding product on the placement plate 11. By rotating the rotating ring 41, the lead screw 4 rotates in the groove 301, and the movable block 42 drives the mounting base 43 and the cutter head 44 to move. At the same time, the movable block 42 drives the pointer 46 to move, and in conjunction with the scale plate 47, observes the adjusted length. Thus, the distance of the cutter head 44 can be adjusted according to different pulp molding products, thereby accurately controlling the cutting size of the pulp molding product.

[0026] Then, the first motor 21 is turned on, causing the threaded rod 22 to rotate and the threaded block 23 to drive the moving plate 24 to descend. At the same time, the second motor 25 and the rotating disk 3 descend, allowing the cutter head 44 to contact the pulp molded product. This causes the pressure plate 35 to press the center of the pulp molded product. Meanwhile, the limiting rod 31 slides through the rotating disk 3, causing the spring 33 to be squeezed between the rotating disk 3 and the fixed ring 34. This allows the pressure plate 35 to limit the pulp molded product, preventing displacement during cutting and improving the accuracy of the ring cutting. Then, the second motor 25 is turned on, causing the rotating disk 3 to drive the cutter head 44 to rotate. At the same time, the guide ring 36 and the limiting rod 31 slide in the movable groove 351, causing the ball bearing 37 to roll in the rolling groove 352. Thus, during the cutting process, the pressure plate 35 can remain stationary, allowing the excess parts of the pulp molded product to be removed.

[0027] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
