Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard box creasing technology, specifically a creasing device for corrugated cardboard box forming. Background Technology

[0002] Corrugated cardboard boxes are packaging paper containers made of corrugated cardboard, mainly used for the transportation and storage of goods. They are made through processes such as die-cutting, creasing, stapling, or gluing, and are characterized by their simplicity, sturdiness, and good cushioning function, which can effectively protect goods and are easy to recycle.

[0003] CN219564286U discloses a corrugated cardboard box creasing device. Through the arrangement of a first electro-hydraulic push rod, a fixed rod, a placement platform, a connecting rod, a pressure rod, a lifting block, and a positioning slider, this device effectively restricts the position of the cardboard, preventing it from shifting during creasing. The extension of the movable end of the first electro-hydraulic push rod facilitates the downward pressure of the pressure rod to restrict the cardboard's position, improving stability during creasing and thus enhancing practicality. However, this patent still has the following problems in actual use:

[0004] The position of the pressure bar is fixed and cannot be adjusted according to the length of the corrugated carton. This means that the pressure bar can only fix corrugated cartons of the same length, which makes it inconvenient to fix and crease cartons of different lengths. This results in certain limitations of the creasing device when producing creasing.

[0005] An indentation device for corrugated carton forming is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a creasing device for corrugated cardboard box forming, in order to solve the problem mentioned in the background art that the position of the current pressure bar is fixed and cannot be adjusted according to the length of the corrugated cardboard box. This results in the pressure bar being able to fix corrugated cardboard boxes of the same length, which in turn makes it inconvenient to fix and creasing cardboard boxes of different lengths, thus limiting the creasing device in the production of creasing.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a creasing device for corrugated cardboard box forming, comprising a base plate and a connecting frame fixed to the top of the base plate, wherein the inner side of the connecting frame is provided with a creasing structure;

[0008] Also includes:

[0009] The top of the base plate is provided with a fixing component, which includes a placement plate, and a gear is rotatably connected to the front of the placement plate, and a control block is fixedly connected to the front of the gear, and a rack is symmetrically meshed with the upper and lower parts of the gear.

[0010] Among them, the front of the placement plate is symmetrically fixed with limit blocks, and the rack slides inside the limit blocks. One side of each rack on both sides is fixedly connected with a connecting rod, and one side of the connecting rod is fixedly connected with a connecting plate.

[0011] One side of the connecting plate is fixedly connected to a first spring, and one side of the first spring is fixedly connected to a fixing plate.

[0012] Preferably, a limiting rod is fixedly connected to one side of the fixing plate, and the limiting rod slides inside the connecting plate.

[0013] Preferably, the fixed plate is rotatably connected to a rotating plate inside, and a fixed rod is rotatably connected to one side of the rotating plate, and the side of the fixed rod away from the rotating plate is fixedly connected to the connecting plate.

[0014] Preferably, the rotating plate has a sliding groove inside, and the fixing rod slides inside the sliding groove with the rotating shaft of the rotating plate.

[0015] Preferably, a pressure block is fixedly connected to one side of the turntable, and the width of the pressure block is greater than or equal to the width of the carton.

[0016] Preferably, the front of the placement plate is provided with a limiting component, the limiting component includes a mounting block, and a second spring is fixedly connected to one side of the mounting block, and a block is fixedly connected to one side of the second spring. A locking block is symmetrically fixed to one side of the block, and the locking block is locked in the tooth gap of the gear.

[0017] Preferably, a limiting strip is symmetrically fixed on one side of the block, and the limiting strip slides inside the mounting block.

[0018] Compared with the prior art, the beneficial effects of this utility model are: this creasing device for corrugated cardboard box forming can fix corrugated cardboard boxes of different lengths, and while fixing the two sides of the corrugated cardboard box, it can also provide auxiliary fixing for the top of the corrugated cardboard box. The specific details are as follows:

[0019] 1. Place the corrugated cardboard box on top of the placement plate, then rotate the control block. The control block will drive the gear to rotate, which will then drive the racks on both sides to move towards each other. The racks on both sides will then drive the connecting rods on both sides to move closer together. The connecting rods on both sides are of different lengths. Then, the connecting rods on both sides will drive the connecting plates on both sides to move closer together. As the connecting plates move, the fixing plate will also move, initially limiting the sides of the corrugated cardboard box. As the connecting plates continue to move, the first spring will be compressed, which will gradually increase the force of the fixing plate on the corrugated cardboard box. The movement of the connecting plate will drive the fixing rod to move, which will then drive the rotating plate to rotate. The rotating plate and the pivot of the fixing rod will slide inside the slide groove, ensuring that the rotating plate can rotate normally. This allows the pressure block to fix the top of the corrugated cardboard box, thus providing auxiliary fixation for the top while fixing the sides of the corrugated cardboard box. The fixing plate moves left and right, so that the first spring can only be compressed when the fixing plate contacts the corrugated cardboard box. Therefore, it can fix corrugated cardboard boxes of different lengths.

[0020] 2. Press the block to the right, and the block will cause the limiting strip to slide inside the mounting block. At the same time, the second spring will be compressed. As the block moves, it will cause the locking block to be removed from the gear teeth, thereby releasing the action on the gear and allowing the gear to rotate freely. When it is necessary to disassemble and re-limit the gear, simply release the block. Attached Figure Description

[0028] 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.

[0029] Please see Figure 1 - Figure 6 This utility model provides a technical solution: a creasing device for corrugated cardboard box forming, including a base plate 1 and a connecting frame 2 fixed to the top of the base plate 1, and a creasing structure 3 is provided on the inner side of the connecting frame 2; a fixing component 4 is provided on the top of the base plate 1, the fixing component 4 includes a placement plate 401, and a gear 402 is rotatably connected to the front of the placement plate 401, and a control block 403 is fixedly connected to the front of the gear 402, and a rack 404 is symmetrically meshed on the upper and lower sides of the gear 402; wherein, a limiting block 405 is symmetrically fixed to the front of the placement plate 401, and the rack 404 slides inside the limiting block 405, and a connecting rod 406 is fixedly connected to one side of each rack 404 on both sides, and a connecting plate 407 is fixedly connected to one side of the connecting rod 406; wherein, a first spring 408 is fixedly connected to one side of the connecting plate 407, and a fixing plate 409 is fixedly connected to one side of the first spring 408, such as Figure 2 , 3As shown in Figure 5, the corrugated cardboard box is placed on top of the placement plate 401. Then, the control block 403 is rotated, which drives the gear 402 to rotate. The gear 402 then drives the racks 404 on both sides to move towards each other. The racks 404 on both sides drive the connecting rods 406 on both sides to move closer to each other. The lengths of the connecting rods 406 on both sides are different. Then, the connecting rods 406 on both sides drive the connecting plates 407 on both sides to move closer to each other. While the connecting plates 407 are moving, the fixing plates 409 will move. The fixing plates 409 on both sides will first contact the two sides of the corrugated cardboard box, so that the fixing plates 409 first limit the two sides of the corrugated cardboard box. When the connecting plates 407 continue to move, the first spring 408 will be compressed, which will gradually increase the force of the fixing plates 409 on the corrugated cardboard box.

[0030] A limiting rod 410 is fixedly connected to one side of the fixed plate 409, and the limiting rod 410 slides inside the connecting plate 407. A rotating plate 412 is rotatably connected inside the fixed plate 409, and a fixed rod 411 is rotatably connected to one side of the rotating plate 412. The side of the fixed rod 411 away from the rotating plate 412 is fixedly connected to the connecting plate 407. A sliding groove 413 is provided inside the rotating plate 412, and the pivot of the fixed rod 411 and the rotating plate 412 slides inside the sliding groove 413. A pressure block 414 is fixedly connected to one side of the rotating plate 412. Furthermore, since the pressure block 414 can only firmly fix the corrugated cardboard box when the first spring 408 is compressed to its shortest distance, this application is only applicable to corrugated cardboard boxes of the same thickness. Figure 5 As shown, when the connecting plate 407 moves, it will drive the fixing rod 411 to move. Then, the fixing rod 411 will drive the rotating plate 412 to rotate. Since the position of the rotating plate 412 and the fixing rod 411 will change when the rotating plate 412 rotates, the pivot of the rotating plate 412 and the fixing rod 411 will slide inside the slide groove 413, thereby ensuring that the rotating plate 412 can rotate normally. Then, when the rotating plate 412 rotates, it will drive the position of the pressure block 414 to change, so that the pressure block 414 can fix the top of the corrugated carton.

[0031] When the first spring 408 is compressed to its shortest distance, the pressure block 414 can just fix the top of the corrugated cardboard box, so that while fixing the sides of the corrugated cardboard box, the top can also be auxiliaryly fixed. The fixing plate 409 moves left and right, so that the first spring 408 can only be compressed when the fixing plate 409 contacts the corrugated cardboard box. Therefore, it can fix corrugated cardboard boxes of different lengths, and the width of the pressure block 414 must be greater than or equal to the width of the cardboard box.

[0032] A limiting component 5 is provided on the front of the placement plate 401. The limiting component 5 includes a mounting block 501, and a second spring 502 is fixedly connected to one side of the mounting block 501. A block 503 is fixedly connected to one side of the second spring 502, and a locking block 505 is symmetrically fixed to one side of the block 503. The locking block 505 is engaged in the tooth gap of the gear 402. A limiting strip 504 is symmetrically fixed to one side of the block 503. Figure 2 As shown, press block 503 to the right, and block 503 will cause the limiting strip 504 to slide inside the mounting block 501. At the same time, the second spring 502 will be compressed. As block 503 moves, it will cause the locking block 505 to be removed from the teeth of gear 402, thereby releasing the action on gear 402 and allowing gear 402 to rotate freely. When it is necessary to limit gear 402 again, simply release block 503, and the limiting strip 504 will slide inside the mounting block 501.

[0033] Working principle: Before using this creasing device for corrugated cardboard box forming, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 6 As shown, firstly, the corrugated cardboard box is placed on top of the placement plate 401. Then, the control block 403 is rotated, which drives the gear 402 to rotate. The gear 402 then drives the racks 404 on both sides to move towards each other. The racks 404 on both sides then drive the connecting rods 406 on both sides to move closer together. The connecting rods 406 on both sides have different lengths. Then, the connecting rods 406 on both sides drive the connecting plates 407 on both sides to move closer together. While the connecting plates 407 are moving, the fixing plates 409 are also moving. The fixing plates 409 on both sides will first contact the two sides of the corrugated cardboard box, thus limiting the two sides of the corrugated cardboard box. As the connecting plates 407 continue to move, the first spring 408 is compressed, which gradually increases the force of the fixing plates 409 on the corrugated cardboard box. When the connecting plates 407 move, they drive the fixing rods 406 on both sides to move closer together. 11. Move, and then the fixing rod 411 will drive the rotating plate 412 to rotate. Since the rotating plate 412 and the fixing rod 411 will change their rotation points when the rotating plate 412 rotates, the rotating shaft of the rotating plate 412 and the fixing rod 411 will slide inside the slide groove 413, thereby ensuring that the rotating plate 412 can rotate normally. Then, when the rotating plate 412 rotates, it will drive the pressure block 414 to change its position, so that the pressure block 414 can fix the top of the corrugated cardboard box. Secondly, when the first spring 408 is compressed to the shortest distance, the pressure block 414 can just fix the top of the corrugated cardboard box, so that while fixing the sides of the corrugated cardboard box, the top can also be auxiliaryly fixed. Moreover, the fixing plate 409 moves left and right, so that the first spring 408 can only be compressed when the fixing plate 409 contacts the corrugated cardboard box. Therefore, it can fix corrugated cardboard boxes of different lengths.

[0034] You can press the block 503 to the right, and the block 503 will cause the limiting strip 504 to slide inside the mounting block 501. At the same time, the second spring 502 will be compressed. As the block 503 moves, it will drive the locking block 505 to be removed from the teeth of the gear 402, thereby releasing the action on the gear 402 and allowing the gear 402 to rotate freely. When it is necessary to limit the gear 402 again, simply release the block 503.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
