[0009] By adopting the above technical solution, a spliced ​​glue coating roller is used, and the movable glue coating roller sleeved on the connecting rod is spliced ​​on the two ends of the fixed glue coating roller. An appropriate number of movable glue coating rollers can be spliced ​​on both sides of the fixed glue coating roller according to the width of the cardboard, and the length of the glue coating roller can be flexibly adjusted to avoid the glue coating roller being too long and the parts of the two ends that exceed the width range of the cardboard being coated with glue, resulting in glue waste, and the glue drying and agglomerating and affecting the later cleaning of the glue coating roller.

[0010] Preferably, a through-hole matching the shape of the rotating shaft is provided through the top of the movable glue coating roller, an insert block 1 is fixedly provided in the center of the front and rear sides of the inner wall of the perforated circle, and a slot 1 matching the shape of the insert block 1 is provided on the surface of the rotating shaft above the upper end and below the lower end of the fixed glue coating roller, the through-hole passes through the rotating shaft and the insert block 1 is located in the slot 1 and slides.

[0011] By adopting the above technical solution, a hole is perforated through the rotating shaft and the insert block is slidably installed in the slot, so that the movable glue coating roller slides in a straight line on the rotating shaft, avoiding the movable glue coating roller from rotating on the rotating shaft during the splicing process, affecting the subsequent splicing and installation.

[0012] Preferably, the right-angled triangle block 1 is adapted to the shapes of the mounting slot 1 and the mounting slot 2, and a spring 1 is fixedly provided on the inner side of the right-angled triangle block 1, the other end of which is fixedly connected to the inner side of the inner cavity of the mounting slot 1 and the mounting slot 2, and a cross bar is fixedly connected to the center of the inner side of the right-angled triangle block 1, and several ends of the cross bars away from the right-angled triangle block 1 are fixedly connected to the shift rod 2, and there are four shift rods 2, and the ends of the four shift rods 2 away from the fixed glue coating roller are movable through the side wall of the rotating shaft and extend to the outside, and a sliding groove 1 adapted to the shape of the four shift rods 2 is provided in the rotating shaft, and the shift rod 2 is located in the sliding groove 1 and slides, and a slot 1 adapted to the shape of the right-angled triangle block 1 is provided on the inner wall surface of the perforated circle.

[0013] By adopting the above technical solution, the movable gluing roller needs to be fixed to the rotating shaft during the splicing process. The movable gluing roller is fixed to the rotating shaft by a right-angled triangle clamping block that is clamped in a clamping groove opened in the perforation of the movable gluing roller, so that the splicing gluing roller can normally glue the cardboard.

[0014] Preferably, a connecting component is provided in the movable glue coating roller, and the connecting component is used to fix the movable glue coating roller to the two ends of the fixed glue coating roller, and to fix the connection between two adjacent movable glue coating rollers. The connecting component includes several rotating grooves 1 opened on the top of the movable glue coating roller, and the several rotating grooves 1 are arranged in a circular array.

[0015] By adopting the above technical solution, the movable glue coating roller is fixedly connected to the fixed glue coating roller through the connecting component, and the movable glue coating rollers are also spliced ​​by the connecting component. The length of the glue coating roller can be flexibly adjusted according to the width of the cardboard, so as to avoid the glue coating roller being too long and the parts at both ends exceeding the width range of the cardboard also being coated with glue, resulting in glue waste, and the glue drying and agglomerating, which affects the later cleaning of the glue coating roller.

[0016] Preferably, a rotating handle is provided in the rotating groove one and can realize rotation. The bottom center of the rotating handle is fixedly connected to an insert rod through a connecting rod two. The end of the insert rod away from the rotating handle is movable and penetrates the side wall of the movable glue coating roller and extends to the outside. The end of the insert rod away from the rotating handle is fixedly connected to a clamping block three. Both ends of the fixed glue coating roller and the end of the movable glue coating roller away from the fixed glue coating roller are provided with a slot two and a rotating groove two that are adapted to the shape of the insert rod and the clamping block three. The slot two is connected to the rotating groove two. After the insert rod and the clamping block three are inserted into the slot two, they are located in the rotating groove two and can realize a clockwise rotation of 90 degrees.

[0017] By adopting the above technical solution, the several insertion rods and the clamping block three on the movable gluing roller are inserted into the slot two opened on the adjacent gluing roller and then extend into the rotating groove two. Thereafter, the insertion rods and the clamping block three are rotated 90 degrees in the rotating groove two by turning the handle, thereby splicing the movable gluing rollers together. Similarly, an appropriate number of movable gluing rollers can be spliced ​​according to the width of the cardboard, thereby avoiding the gluing roller being too long and the parts at both ends that exceed the width range of the cardboard being coated with glue, resulting in glue waste, and the glue drying and agglomerating, which affects the later cleaning of the gluing roller.

[0019] By adopting the above technical solution, the surface of the friction block in contact with the connecting rod 2 abuts against the surface of the connecting rod 2, generating friction. Under the action of the friction, the connecting rod cannot rotate, thereby preventing the insertion rod and the clamping block 3 from rotating in the rotating groove 2, resulting in loose splicing of the movable glue coating roller, thereby improving the stability of the device.

[0020] Preferably, a second clamping component is fixedly connected to the top of one side of the push rod, and the second clamping component includes a mounting block fixedly connected to the top of one side of the push rod, and an inserting block is fixedly connected to the bottom of the mounting block. A sliding groove four is provided on one side of the inserting block that is adapted to the shape of the second right-angled triangle clamping block, and the second right-angled triangle clamping block is located in the fourth sliding groove and slides. A spring four is fixedly connected to the inner end of the second right-angled triangle clamping block, and the other end is fixed to the inner side of the inner cavity of the fourth sliding groove. A slot three that is adapted to the shape of the second inserting block is provided at the bottom of the inner cavity of the rotating groove, and a slot two that is adapted to the shape of the second right-angled triangle clamping block is provided on the inner wall of the inner cavity of the slot three.

[0021] By adopting the above technical solution, when rotating the insertion rod, it is necessary to press the push rod, and the push rod pushes the friction block away from the connecting rod 2, so that the friction between them disappears, allowing the insertion rod to rotate. When the push rod is pressed, the installation block drives the insertion block 2 to be inserted into the slot 3, and at the same time, the right-angled triangle clamping block 2 is clamped in the clamping slot 2, preventing the push rod from rebounding under the action of the spring 3. The operator does not need to press the push rod by hand all the time, and the operation is simple and convenient.

[0022] Preferably, a lever 1 is fixed to the top of the inner end of the second right-angled triangle block, and the top of the lever 1 movably passes through the side wall of the mounting block and extends to the outside. The second insertion block and the top of the mounting block are both provided with a sliding groove 5 that is adapted to the shape of the lever 1.

[0023] By adopting the above technical solution, the lever 1 is moved in the slide groove 5, driving the right-angled triangle block 2 to slide into the slide groove 4, so that the insertion block 2 is no longer stuck in the slot 3, and the push rod rebounds to its original position under the action of the spring 3, which makes the operation simple and convenient.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] By arranging a movable glue coating roller, a clamping component and a connecting component, the movable glue coating roller can be fixedly spliced ​​on both sides of the fixed glue coating roller, so that several movable glue coating rollers and the fixed glue coating roller form an integral glue coating roller, and the number of spliced ​​movable glue coating rollers can be flexibly controlled according to the width of the cardboard, so that the length of the glue coating roller can adapt to the width of the cardboard, avoiding that the glue coating roller is too long and the parts of the two ends that exceed the width range of the cardboard are also coated with glue, resulting in glue waste, and the glue is dried and agglomerated, which affects the later cleaning of the glue coating roller.

[0046] The following is combined with Figures 1-11 This application is described in further detail.

[0047] The embodiment of the present application discloses a cardboard gluing device.

[0048] Reference Figure 1-Figure 3 A cardboard gluing device includes a workbench 1, which is placed on the ground. Two side panels 2 are fixedly connected to both sides of one end of the workbench 1 by bolts. Two mounting brackets 3 are respectively fixedly installed on the inner sides of the two side panels 2. A gluing roller assembly 4 for gluing cardboard is rotatably arranged between the two mounting brackets 3. The gluing roller assembly 4 includes a rotating shaft 41. The centers of both ends of the rotating shaft 41 are fixedly connected with a connecting rod 42. A fixed gluing roller 411 is fixedly sleeved on the outer center of the rotating shaft 41. The fixed gluing roller 411 is rotatably installed between the inner sides of the two mounting brackets 3 through the connecting rods 42 at both ends. A U-shaped through hole 431 that matches the shape of the connecting rod 42 is opened in the center of one side of the limit plate 43. The surface of the limit plate 43 is fixedly connected to the position on both sides of the U-shaped through hole 431, and the U-shaped through hole 431 passes through the connecting rod 42. Bolt holes are opened on the connecting piece 432, and the limit plate 43 is fixed to the connecting rod 42 by passing the threaded bolt 433 through the two bolt holes and tightening the nut on the threaded bolt 433. A number of spare movable glue coating rollers 44 are movably sleeved on the surface of the connecting rod 42 between the outer side of the limit plate 43 and the inner side of the mounting frame 3, and the surfaces of the movable glue coating rollers 44 that contact the outer side of the limit plate 43 and the inner side of the mounting frame 3 abut against the outer side of the limit plate 43 and the inner side of the mounting frame 3 to prevent the movable glue coating rollers 44 from sliding on the connecting rod 42.

[0049] The limiting plate 43 limits the movable glue coating roller 44 on the connecting rod 42 to prevent it from sliding on the connecting rod 42. When the movable glue coating roller 44 needs to be fixedly connected to the fixed glue coating roller 411, the nut needs to be screwed and the nut needs to be unscrewed from the threaded bolt 433. Then, the threaded bolt 433 is removed from the bolt holes on the two connecting pieces 432. At this time, the limiting plate 43 is no longer fixedly sleeved on the connecting rod 42. The limiting plate 43 can be removed from the connecting rod 42. Then, the spare movable glue coating roller 44 can be slid onto the rotating shaft 41 and fixed to the fixed glue coating roller 411. The appropriate number of movable glue coating rollers 44 can be spliced ​​according to the width of the cardboard, so that the length of the entire glue coating roller is adapted to the width of the cardboard, thereby avoiding that the glue coating roller is too long and the parts that exceed the width range of the cardboard at both ends are also coated with glue, resulting in glue waste. Moreover, the glue dries and agglomerates, which affects the cleaning of the glue coating roller in the later stage.

[0050] refer to Figure 2 、 Figure 3 The side of the movable glue coating roller 44 is penetrated by a through hole 441 for the rotation shaft 41 to pass through, and the insert block 410 is symmetrically fixedly installed on both sides of the inner wall of the through hole 441. The surface of the rotation shaft 41 is symmetrically provided with a slot 412 that is adapted to the shape of the insert block 410 at positions on both sides of the fixed glue coating roller 411. The movable glue coating roller 44 passes through the rotation shaft 41 through the through hole 441 and is movably sleeved on the surface of the rotation shaft 41, and the insert block 410 is located in the slot 412 and slides so that the movable glue coating roller 44 slides linearly on the rotation shaft 41 to prevent it from rotating on the rotation shaft 41.

[0051] The movable glue coating roller 44 is passed through the rotating shaft 41, and the block 1 410 is aligned with the slot 1 412, so that the movable glue coating roller 44 slides linearly on the rotating shaft 41, which is convenient for the later splicing of the movable glue coating roller 44 through the connecting component 48.

[0052] refer to Figure 4 、 Figure 5A plurality of second mounting grooves 46 and a plurality of first mounting grooves 413 are symmetrically arranged on the left and right sides of both ends of the rotating shaft 41, and a clamping assembly 47 is arranged in the first mounting groove 413 and the second mounting groove 46, and the clamping assembly 47 arranged in the first mounting groove 413 and the second mounting groove 46 is mirror-symmetrical. The clamping assembly 47 includes a right-angled triangle clamping block 471 that is adapted to the shape of the first mounting groove 413 and the second mounting groove 46. The right-angled triangle clamping block 471 is located in the first mounting groove 413 and the second mounting groove 46 and realizes horizontal sliding. The right-angled triangle clamping block 471 located in the first mounting groove 413 and the second mounting groove 46 is mirror-symmetrical, and a spring 4 is fixedly connected to the inner side of the right-angled triangle clamping block 471. 73, one end of spring 1 473 away from right-angled triangle block 1 471 is fixedly connected to the inner side of the inner cavity of mounting groove 1 413 and mounting groove 2 46, slot 1 472 is arranged on the inner wall of the circumference of through-hole 441, and slot 1 472 is adapted to the shape of right-angled triangle block 1 471, cross bar 474 is fixedly connected to the center of the inner side of right-angled triangle block 1 471, and cross bar 474 is fixedly connected, and four shift rods 2 475 are provided and are respectively fixedly installed on one end of corresponding cross rods 474 away from right-angled triangle block 1 471, and four shift rods 2 475 are respectively located in four slide grooves 1 476 arranged in rotating shaft 41 and realize horizontal sliding, and shift rod 2 475 is located in slide groove 1 476 and realizes sliding.

[0053] When the movable glue coating roller 44 slides at both ends of the rotating shaft 41, the inclined surface of the right-angled triangle clamping block 1 471 is subjected to the force given by the movable glue coating roller 44. Through the decomposition of the force, it can be known that the right-angled triangle clamping block 1 471 is subjected to the force in the direction of the installation groove 1 413 and the installation groove 2 46, so that the right-angled triangle clamping block 1 471 slides toward the installation groove 1 413 and the installation groove 2 46. When the movable glue coating roller 44 slides to abut the side of the adjacent glue coating roller, the right-angled triangle clamping block 1 471 at the corresponding position rebounds under the action of the spring 1 473 and is clamped in the clamping groove 1 472. The movable glue coating roller 44 is fixed on the rotating shaft 41, and the movable glue coating roller 44 cannot slide on the rotating shaft 41. Then it is spliced ​​and fixed with the adjacent glue coating roller through the connecting component 48 to complete the splicing of the glue coating rollers. When the movable glue coating roller 44 needs to be removed from the rotating shaft 41, the second lever 475 is moved, and the second lever 475 drives the right-angled triangle block 1 471 to slide into the installation groove 1 413 and the installation groove 2 46. At this time, the right-angled triangle block 1 471 will no longer be clamped and fixed on the rotating shaft 41, and the movable glue coating roller 44 can be removed from the rotating shaft 41.

[0054] refer to Figure 6 、 Figure 7, the connecting component 48 is arranged in the movable glue coating roller 44, and the connecting component 48 includes a plurality of rotating grooves 485 arranged in a circular array. The plurality of rotating grooves 485 are opened on the top of the movable glue coating roller 44, and the plurality of rotating handles 484 are rotatably installed in the center of the bottom of the plurality of rotating grooves 485 through the connecting rod 2 483. The plurality of connecting rods 2 483 are away from the rotating handle 484, and the end of the insertion rod 481 away from the rotating handle 484 passes through the side wall of the movable glue coating roller 44 and is fixedly connected to the center of the top of the insertion rod 481. A rotating hole is provided at the bottom of the roller 44 for the rotation of the insertion rod 481, and a number of insertion rods 481 are rotatably installed in the rotating hole. The end of the insertion rod 481 away from the rotating handle 484 extends to the outside of the rotating hole and is fixedly connected to the clamping block 3 482. Slot 2 486 and rotation groove 2 487 that are adapted to the shapes of the number of insertion rods 481 and clamping block 3 482 are provided at both ends of the fixed glue coating roller 411, and the slot 2 486 and rotation groove 2 487 are connected, and are also provided at the end of the movable glue coating roller 44 away from the fixed glue coating roller 411.

[0055] When the movable glue coating roller 44 slides to abut the side of the adjacent glue coating roller, the insertion rod 481 and the clamping block three 482 are inserted into the slot two 486 and extend into the rotation groove two 487. Then the rotating handle 484 is rotated clockwise. The rotating handle 484 drives the insertion rod 481 and the clamping block three 482 to rotate 90 degrees clockwise in the rotation groove two 487. At this time, the movable glue coating roller 44 is fixedly spliced ​​together with the adjacent glue coating roller.

[0056] Reference pictures, Figure 9 The third mounting groove 414 is provided in the movable glue coating roller 44 at a position corresponding to one side of the second connecting rod 483. The anti-rotation component 49 is provided in the third mounting groove 414. The anti-rotation component 49 includes a friction block 491 provided in the third mounting groove 414 and capable of sliding. The arcuate surface of the friction block 491 abuts against the surface of the second connecting rod 483. The center of the side of the friction block 491 away from the second connecting rod 483 is fixedly connected to the second spring 493. The end of the second spring 493 away from the friction block 491 is fixedly connected to the third mounting groove 414. On the outside of the inner cavity, an inclined groove 494 is provided at the top center of the friction block 491, and a push rod 495 with the bottom located in the inclined groove 494 is movably installed on the top of the rotating groove 485. A connecting plate 496 is fixedly connected to one side of the push rod 495. The connecting plate 496 is located in the slide groove 3 497 provided in the movable glue coating roller 44 and realizes horizontal sliding. A spring 3 498 is fixedly connected to the bottom of the connecting plate 496, and the end of the spring 3 498 away from the connecting plate 496 is fixedly connected to the bottom of the inner cavity of the slide groove 3 497.

[0057] By setting a friction block 491 that abuts the surface of the second connecting rod 483, friction is created between the second connecting rod 483 and the friction block 491, thereby preventing the second connecting rod 483 from rotating, and further preventing the installation rod 481 and the block three 482 from rotating in the second rotating groove 487 due to shaking, which makes the splicing between the movable glue coating roller 44 not firm. When it is necessary to rotate the installation rod 481 and the block three 482, the push rod 495 is pushed, and the push rod 495 is pushed toward the inclined groove 494, applying the thrust on the inclined surface of the inclined groove 494, and then the friction block 491 is forced to slide toward the installation groove three 414, and no longer abuts against the second connecting rod 483, and then the friction disappears, and the installation rod 481 and the block three 482 can be rotated.

[0058] refer to Figure 10 、 Figure 11 , the clamping assembly 2 45 is fixedly connected to the top of one side of the push rod 495, the clamping assembly 2 45 includes a mounting block 451 fixedly connected to the top of one side of the push rod 495, the insertion block 2 452 is fixedly connected to the bottom of the mounting block 451, the right-angled triangle clamping block 2 453 is located in the slide groove 454 opened on one side of the insertion block 2 452 and slides, the inner end of the right-angled triangle clamping block 2 453 is fixedly connected to the spring 455, and the end of the spring 455 away from the right-angled triangle clamping block 2 453 is fixedly connected It is connected to the inner side of the inner cavity of the sliding groove 454, and the slot three 457 for the insertion block 2 452 is provided at the bottom of the inner cavity of the rotating groove 1 485. The slot two 456 for the right-angled triangle clamping block 2 453 to be clamped is provided on the side wall of the inner cavity of the slot three 457. The top of the inner end of the right-angled triangle clamping block 2 453 is fixedly connected with a shift rod 1 458 which movably penetrates the side wall of the mounting block 451 and extends to the outside. The sliding groove five 459 for the shift rod 1 458 to slide is provided at the top of the insertion block 2 452 and the mounting block 451.

[0059] When the push rod 495 is pressed, the installation block 451 drives the insertion block 2 452 to be inserted into the slot 3 457. At the same time, the right-angled triangle block 2 453 is clamped in the clamping slot 2 456 to prevent the push rod 495 from rebounding under the action of the spring 3 498. The operator does not need to press the push rod 495 with his hands all the time. The operation is simple and convenient. At the same time, the shift rod 1 458 is shifted in the slide groove 5 459 to drive the right-angled triangle block 2 453 to slide into the slide groove 454, so that the insertion block 2 452 is no longer clamped in the slot 3 457. The push rod 495 rebounds to its original position under the action of the spring 3 498. The operation is simple and convenient.

[0060] The implementation principle of a cardboard gluing device in an embodiment of the present application is as follows: when the movable gluing roller 44 slides to abut the side of the adjacent gluing roller, the right-angled triangle block 1 471 at the corresponding position rebounds and is engaged in the card slot 1 472 under the action of the spring 1 473, fixing the movable gluing roller 44 on the rotating shaft 41, and the movable gluing roller 44 cannot slide on the rotating shaft 41. When the movable gluing roller 44 slides to abut the side of the adjacent gluing roller, the insertion rod 481 and the card block 3 482 are inserted into the slot 2 486 and extend into the rotating groove 2 487. Then, the rotating handle 484 is rotated clockwise, and the rotating handle 484 drives the insertion rod 481 and the card block 3 482 to rotate 90 degrees clockwise in the rotating groove 2 487. At this time, the movable gluing roller 44 is fixedly spliced ​​together with the adjacent gluing roller.

[0061] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
