Description

Technical Field

[0001] This utility model relates to the field of paperboard processing technology, specifically a high-efficiency pressing equipment for paperboard production. Background Technology

[0002] Paperboard, also known as cardboard, is a thick sheet of paper made from various pulps and interwoven fibers. It is usually made from various plant fibers, but some also contain non-plant fibers. It is made on a paperboard machine. Some special paperboards also contain animal fibers such as wool or mineral fibers such as asbestos.

[0003] When processing cardboard, it needs to be pressed together. Cardboard pressing refers to the process of bonding two pieces of cardboard together by squeezing. Existing cardboard pressing equipment often requires manual feeding of the cardboard onto the pressing table. After the pressing machine is started, personnel should move away from the pressing machine and out of the danger zone to prevent accidental contact and injury. However, in actual operation, some operators often violate the rules and stand in the danger zone. Due to negligence, personnel may fail to pull their arms out of the pressing area in time or accidentally put them into the pressing area, which may cause the equipment to crush the operator's body and cause a safety accident. To address this, we have designed a high-efficiency cardboard pressing machine to make the equipment safer to use. Utility Model Content

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.

[0021] Please see Figure 1 and Figure 4 In this embodiment of the present invention, a high-efficiency cardboard pressing device includes a frame 1 and a pressing worktable 2. The pressing worktable 2 is arranged in the middle of the frame 1, and a conveying mechanism 3 is installed in the middle of the pressing worktable 2. The conveying mechanism 3 includes a conveying roller 19, a conveyor belt 13, a lower pressure plate 15, and a motor 4. The conveying roller 19 is installed at both ends of the pressing worktable 2 and is connected to the conveyor belt 13 for transmission. One end of the conveying roller 19 is directly connected to the output shaft of the motor 4 installed at the bottom of the pressing worktable 2. A lower pressure plate 15 is arranged inside the conveyor belt 13 and is tightly attached to the upper belt body. The lower pressure plate 15 is fixedly connected to the frame 1. The conveying mechanism 3 of the present invention can quickly convey the cardboard from the pressing worktable 2 after the cardboard is pressed, without the need for personnel to reach into the equipment to pick it up, which not only makes the cardboard output more efficient but also safer.

[0022] Please see Figure 1-3 A hydraulic cylinder 5 is installed on the top of the frame 1. An upper pressure plate 7 is installed at the bottom of the hydraulic cylinder 5. Horizontal bars 8 are installed on both sides of the upper pressure plate 7. The horizontal bars 8 pass through the sliding openings 9 on both sides of the frame 1, and the ends of the horizontal bars 8 are fixedly connected to vertical bars 10 installed inside the frame 1. A vertical rack 11 is installed on one side of the vertical bar 10. The vertical rack 11 meshes with a gear 16 installed inside the frame 1. A longitudinal bar 12 is provided on the gear 16. A longitudinal rack 14 is installed on the side of the longitudinal bar 12 opposite to the gear 16. The longitudinal rack 14 meshes with the gear 16.

[0028] The working principle of this utility model is as follows: When in use, the stacked and glued cardboard is first placed on the conveying mechanism 3 of the pressing workbench 2. Then, the hydraulic cylinder 5 is started, and the hydraulic cylinder 5 extends to drive the upper pressure plate 7 to move downward. The upper pressure plate 7 drives the vertical rod 10 to move downward through the horizontal bar 8. The vertical rack 11 on the vertical rod 10 meshes with the gear 16 to drive the gear 16 to rotate. The gear 16 meshes with the longitudinal rack 14 to drive the longitudinal rod 12 to move towards the front of the equipment, thereby pushing the push plate 17 to push the personnel standing in front of the equipment away from the equipment, forming a safety isolation zone in front of the equipment to prevent personnel from accidentally putting their arms into the pressing area and being crushed. After the pressing is completed, the motor 4 is started. The motor 4 drives the conveyor roller 19 to rotate and transport the pressed product out of the equipment through the conveyor belt 13 so that the cardboard can be processed in other ways.
