Technical Field
[0001] The utility model belongs to the technical field of carton processing, and particularly relates to a crease pressing-down device for carton cardboard processing. Background Art
[0002] Carton cardboard is the paper material required for making cartons, usually composed of face paper, sandwich paper and bottom paper. Among them, the sandwich paper is corrugated paper, which is made by interleaving and pressing double-layer or multi-layer cardboard longitudinally and transversely, and has high strength and toughness. It is widely used in the fields of packaging, transportation, logistics, etc.
[0003] When cartons are produced and processed, the cardboard needs to be cut into appropriate sizes first, and then creases are pressed on the cardboard through a crease pressing-down device, so as to facilitate folding the cardboard into cartons. Due to the different uses of cartons, the thickness of the cardboard used is also very different. Although the existing crease pressing-down devices can perform basic processing functions, in the actual use process, the depth of the creases that each device can press down is fixed, and the practicability is low, resulting in an increase in the cost of carton production equipment. Therefore, it needs to be improved. Content of the Utility Model

Specific embodiments
[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0022] As Figures 1 to 5 shown, the present utility model provides a crease pressing device for processing carton paperboard, including a workbench 1. Both the left and right sides of the top of the workbench 1 are fixedly installed with side plates 2. The right side of the side plate 2 is fixedly installed with a motor 3. The other end of the output shaft of the motor 3 is fixedly connected with a rotating shaft 4. The left end of the rotating shaft 4 extends to the outside of the side plate 2 and is movably sleeved with the inner wall of the side plate 2. The inside of the side plate 2 is movably sleeved with a movable shaft 5 located on the left side above the workbench 1. Discs 6 are fixedly sleeved on the outer surfaces of both the movable shaft 5 and the rotating shaft 4. The number of discs 6 is two. The inside of the top ends of both discs 6 is movably sleeved with threaded rods 7. The top of the outer surface of the threaded rod 7 is fixedly sleeved with a rotating block 8. The outer surface of the threaded rod 7 is threadedly sleeved with a moving block 9. The outer surface of the moving block 9 is movably connected with the inner wall of the disc 6. A round rod 10 is fixedly connected between the moving blocks 9. The outer surface of the round rod 10 is movably sleeved with a lifting frame 11. The bottom of the lifting frame 11 is fixedly connected with a connecting rod 12. The bottom of the connecting rod 12 is fixedly connected with a pressing plate 13. Limiting blocks 14 located inside the side plates 2 are fixedly installed on both the left and right sides of the pressing plate 13. The outer surface of the limiting block 14 is movably connected with the inner wall of the side plate 2.
[0023] The operator can rotate the rotating block 8, causing the threaded rod 7 to drive the moving block 9 downward, which in turn causes the moving block 9 to drive the round rod 10 downward, thereby reducing the rotation radius of the round rod 10. This enables adjustment of the downward movement distance of the pressing plate 13, allowing for indentation processing of cardboard of different thicknesses and preventing the phenomenon of directly breaking too thin cardboard.
[0024] Wherein, the front and back surfaces of the pressing plate 13 are fixedly installed with first indentation knives 15, and the bottom of the pressing plate 13 is fixedly installed with a second indentation knife 16.
[0025] As a technical optimization solution of the present utility model, by providing the first indentation knife 15 and the second indentation knife 16, indentation processing of the cardboard can be achieved.
[0026] Wherein, an activity box 17 is movably sleeved inside the workbench 1, and a through hole 18 is opened at the top of the activity box 17.
[0027] As a technical optimization solution of the present utility model, by providing the through hole 18, when the through hole 18 generates suction, the cardboard can be adsorbed, thus preventing the cardboard from moving.
[0028] Wherein, a pull rod 19 is fixedly installed on the front surface of the activity box 17. The front end of the pull rod 19 penetrates through the workbench 1 and extends to the front surface of the workbench 1 and is movably sleeved with the inner surface of the workbench 1. A mounting block 20 is fixedly installed at the bottom of the activity box 17.
[0029] As a technical optimization solution of the present utility model, the operator can pull the pull rod 19 outwards, causing the activity box 17 to drive the cardboard forward.
[0030] Wherein, a spring 21 is fixedly installed on the back surface of the mounting block 20. The rear end of the spring 21 is fixedly connected to a fixed block 22, and the top of the fixed block 22 is fixedly connected to the bottom of the workbench 1.
[0031] As a technical optimization solution of the present utility model, when the activity box 17 moves forward, the spring 21 will be stretched, driving the activity box 17 to reset.
[0032] Wherein, table legs 23 are fixedly installed at the four corners of the bottom of the workbench 1. A fixing plate 24 is fixedly installed between the table legs 23 on the left side below the workbench 1. An air pump 25 is fixedly installed on the top of the fixing plate 24.
[0033] As a technical optimization solution of the present utility model, by providing the fixing plate 24, the fixing plate 24 can play a role in supporting and fixing the air pump 25.
[0034] An air outlet pipe 26 is fixedly installed at the bottom of the air pump 25 , an air intake hose 27 is fixedly installed on the right side of the air pump 25 , and the other end of the air intake hose 27 is fixedly connected to the bottom of the movable box 17 .
[0035] As a technical optimization solution of the present invention, the operator can start the air pump 25 to make the air intake hose 27 generate suction, so that the through hole 18 can generate suction.
[0036] The working principle and use process of this utility model:
[0037] First, the operator rotates the rotating block 8 according to the thickness of the cardboard to be processed, so that the rotating block 8 drives the threaded rod 7 to rotate, and then the threaded rod 7 drives the moving block 9 to move downward, so that the round rod 10 moves downward, so that the rotation radius of the round rod 10 becomes smaller, so that the downward movement distance of the pressing plate 13 becomes shorter, so that the cardboards of different thicknesses can be creased and pressed down. Then the operator places the cardboard on the upper surface of the workbench 1, and starts the air pump 25 to generate suction in the air intake hose 27, so that the through hole 18 generates suction, so that the cardboard can be adsorbed, thereby preventing the cardboard from moving during processing.
[0038] Then the operator starts the motor 3, so that the shaft 4 drives the disc 6 to rotate, and then the round rod 10 can rotate with the shaft 4 as the axis, so as to squeeze and push the inner surface of the lifting frame 11, and then drive the lifting frame 11 and the connecting rod 12 to move downward, so that the pressing plate 13 drives the first creasing knife 15 and the second creasing knife 16 to move downward under the limiting action of the limiting block 14, so as to process the cardboard. When the cardboard folding is completed, the operator pulls the pull rod 19 outward, so that the movable box 17 drives the cardboard to move outward and away from the bottom of the pressing plate 13, so that the cardboard can be removed, thereby improving the safety of the device and preventing the operator from putting his hand under the pressing plate 13.
