Description

Technical Field

[0001] This utility model relates to the field of coated paper slitting technology, specifically a clamping device for slitting coated paper. Background Technology

[0002] Coated paper is a composite material made by coating plastic particles onto the surface of paper using a casting machine. Its main characteristics are oil and water resistance, and heat sealing capability. Different uses utilize different properties. Its oil-resistant properties make it suitable for packaging fried foods; its waterproof properties make it suitable for coated paper packaging; and its heat-sealing properties allow it to be used with automatic packaging machines. Its applications are extremely wide-ranging. In the processing of coated paper, a winding mechanism rolls the paper into a large roll. Sometimes, according to customer requirements, a slitting machine is used to cut the coated paper into single rectangular sheets. The coated paper is then conveyed to the cutter by a conveying device such as an electric roller, and then the cutter is driven by a cylinder to cut it. However, some existing paper cutting equipment for coated paper has grooves at the cutting edge to protect the blade. Since coated paper is relatively soft, it deforms during cutting to fit into the grooves and is pressed into them by the cutter, making it difficult to cut. Utility Model Content

[0018] 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.

[0019] Example: Figure 1-6 As shown, this utility model provides a clamping device for slitting coated paper, including a worktable 1. The worktable 1 is equipped with an unwinding assembly 2, an auxiliary assembly 4, a conveying assembly 8, a cutting assembly 6, and a limiting assembly 7. A fixing frame 5 is fixedly installed on the worktable 1. The cutting assembly 6 includes a lifting plate 601, which is slidably installed within the fixing frame 5. A cutting blade 602 is fixedly installed in the center of the lower surface of the fixing frame 5. A blade groove 101 is provided on the worktable 1, and the blade groove 101 is located directly below the cutting blade 602. Multiple equally spaced insert rods 605 are inserted through both sides of the lifting plate 601. A pressure plate 603 is fixedly installed at one end of each insert rod 605 located on the same side of the lifting plate 601. A spring 606 is sleeved on each insert rod 605. A cylinder 604 is fixedly installed at the top of the fixing frame 5, and the output end of the cylinder 604... The upper surface of the lifting plate 601 is fixedly connected to the coated paper roll 3 to be cut. The coated paper roll 3 is placed on the unwinding assembly 2 and the limiting assembly 7 is used to limit the coated paper roll 3. One end of the coated paper roll 3 is pulled through the auxiliary assembly 4, the conveying assembly 8, and the cutting assembly 6. The coated paper is conveyed by the conveying assembly 8. The auxiliary assembly 4 can keep the coated paper flat during the conveying process. After the coated paper moves to the specified length, the conveying assembly 8 stops working. The cylinder 604 drives the lifting plate 601 and the cutting blade 602 to descend. The pressure plate 603 first contacts the coated paper. As the lifting plate 601 descends, the lifting plate 601 descends and compresses the spring 606. The elastic force of the spring 606 applies downward pressure to the pressure plate 603 to press the two sides of the coated paper before cutting. The lifting plate 601 continues to descend, driving the cutting blade 602 to insert into the blade groove 101, thereby cutting the coated paper.

[0020] The limiting component 7 includes two symmetrically distributed limiting plates 701, which are slidably mounted on the worktable 1. A bidirectional lead screw 703 is rotatably mounted inside the worktable 1, and the bidirectional lead screw 703 is threaded into the bottom end of the two limiting plates 701. A first motor 702 is fixedly mounted on one side of the worktable 1, and the output end of the first motor 702 is fixedly connected to one end of the bidirectional lead screw 703. According to the length of the coated paper roll 3, the first motor 702 drives the bidirectional lead screw 703 to rotate, and the bidirectional lead screw 703 drives the two limiting plates 701 to slide towards each other and limit the coated paper roll 3.

[0021] The auxiliary component 4 includes a first sliding frame 402, which is slidably mounted on the worktable 1. A second rotating roller 403 is rotatably mounted inside the first sliding frame 402. A first rotating roller 401 is rotatably mounted inside the worktable 1, and the first rotating roller 401 is located directly below the second rotating roller 403. A first threaded rod 404 is threadedly inserted into the worktable 1, and the bottom end of the first threaded rod 404 is rotatably connected to the top end of the first sliding frame 402. Rotating the first threaded rod 404 causes the first sliding frame 402 and the second rotating roller 403 to descend, which, together with the first rotating roller 401, clamps the coated paper.

[0022] The conveying assembly 8 includes a second sliding frame 801, which is slidably mounted within a fixed frame 5. A second drive roller 803 is rotatably mounted within the second sliding frame 801. A first drive roller 802 is rotatably mounted within the worktable 1, located directly below the second drive roller 803 and flush with the first rotating roller 401. A second threaded rod 811 is threadedly inserted into the fixed frame 5, with its bottom end rotatably connected to the top end of the second sliding frame 801. A drive shaft 804 is rotatably mounted on one side of the fixed frame 5, and the drive shaft 804 is inserted through one side of the second sliding frame 801. A second motor 805 is fixedly mounted on the top of the fixed frame 5, and the output end of the second motor 805 is fixedly connected to the top of the drive shaft 804. A third bevel gear 809 and a first bevel gear 807 are fixedly mounted on one end of the rotating shaft of the first drive roller 802 and the second drive roller 803, respectively. A second bevel gear 808 is rotatably mounted on one side of the second sliding frame 801. The sliding bracket 801 is mounted on the drive shaft 804, and the second bevel gear 808 meshes with the first bevel gear 807. A fourth bevel gear 810 is fixedly mounted on the bottom end of the drive shaft 804. The fourth bevel gear 810 is mirror-image of the second bevel gear 808, and it meshes with the third bevel gear 809. Rotating the second threaded rod 811 causes the second sliding frame 801 and the second drive roller 803 to descend, cooperating with the first drive roller 802 to clamp the coated paper. As the second sliding frame 801 descends... The first bevel gear 807 and the second bevel gear 808 descend synchronously. The second bevel gear 808 slides down along the drive shaft 804. The second motor 805 drives the drive shaft 804 to rotate. The drive shaft 804 drives the second bevel gear 808 and the fourth bevel gear 810 to rotate. The second bevel gear 808 and the fourth bevel gear 810 drive the second drive roller 803 and the first drive roller 802 to rotate synchronously in opposite directions through the first bevel gear 807 and the third bevel gear 809, respectively, to transport the coated paper.

[0023] Working principle: In use, the coated paper roll 3 to be cut can be placed on the unwinding assembly 2. The first motor 702 drives the bidirectional lead screw 703 to rotate. The bidirectional lead screw 703 drives the two limiting plates 701 to slide towards each other and limit the coated paper roll 3. One end of the coated paper roll 3 is pulled through between the first rotating roller 401 and the second rotating roller 403 and between the first drive roller 802 and the second drive roller 803. The first threaded rod 404 is rotated to drive the first sliding frame 402 and the second rotating roller 403 to descend, which, together with the first rotating roller 401, clamps the coated paper. The second threaded rod 811 is rotated to drive the second sliding frame 801 and the second drive roller 703 to descend. The second drive roller 803 descends, cooperating with the first drive roller 802 to clamp the coated paper. As the second sliding frame 801 descends, it drives the first bevel gear 807 and the second bevel gear 808 to descend synchronously. The second bevel gear 808 slides down along the drive shaft 804. The second motor 805 drives the drive shaft 804 to rotate. The drive shaft 804 drives the second bevel gear 808 and the fourth bevel gear 810 to rotate. The second bevel gear 808 and the fourth bevel gear 810 drive the second drive roller 803 and the first drive roller 802 to rotate synchronously in opposite directions through the first bevel gear 807 and the third bevel gear 809, respectively, to transport the coated paper.

[0024] The coated paper moves below the cutting blade 602. After the coated paper moves to a specified length, the conveying assembly 8 stops working. The cylinder 604 drives the lifting plate 601 and the cutting blade 602 to descend. The pressure plate 603 first contacts the coated paper. As the lifting plate 601 descends, it compresses the spring 606. The elastic force of the spring 606 applies downward pressure to the pressure plate 603 to press the coated paper on both sides before cutting. The lifting plate 601 continues to descend, driving the cutting blade 602 to insert into the blade groove 101, thereby cutting the coated paper.
