The adjustable vertical plate assembly 5 comprises a plate seat 51, a top plate 52, an inner slide plate 53, an inner slide groove 54 and a limiting through-rod 55. The plate seat 51 is fixed to the top surface of the base 1, the top plate 52 is arranged on the top of the plate seat 51, and the inner slide plate 53 is fixed to the bottom surface of the top plate 52. An inner slide groove 54 corresponding to the inner slide plate 53 is provided on the top of the plate seat 51, and the bottom end of the inner slide plate 53 is movably inserted into the inner slide groove 54, so that the top plate 52 can slide up and down to change the overall length of the adjustable vertical plate assembly 5, thereby realizing the adaptive adjustment of the height of the side pressure plate 7. A plurality of through holes 56 corresponding to the limiting through-rod 55 are evenly provided on the surface of the inner slide plate 53. The two side surfaces of the seat 51 are provided with side slots 57 corresponding to the limiting penetration rod 55, the limiting penetration rod 55 passes through one of the through holes 56, and the two ends of the limiting penetration rod 55 respectively pass through the two side slots 57 on the two side surfaces of the plate seat 51, and the limiting penetration rod 55 after passing through can play a stable supporting and limiting role for the inner slide plate 53 and the top plate 52, to ensure the stability of the side pressure plate 7 after the height is adjusted. Subsequently, the limiting penetration rod 55 only needs to pass through the through holes 56 at other positions of the inner slide plate 53 to change the height of the side pressure plate 7. The adjustable vertical plate assembly 5 also includes a T-shaped shaft rod 58 and a limiting baffle 59. The two side surfaces of the plate seat 51 are fixed with T-shaped shaft rods 58, and a limiting baffle 59 is rotatably sleeved on the T-shaped shaft rod 58. The top of the limiting baffle 59 will engage the side slots 57 The cover can effectively block and limit the limiting penetrating rod 55. An inner movable groove 510 is provided inside the limiting baffle 59. A spring 511 and an inner movable block 512 are provided inside the inner movable groove 510. A bottom clamping rod 513 is fixed to the bottom surface of the inner movable block 512. Two limiting clamping grooves 514 corresponding to the bottom clamping rod 513 are symmetrically provided on the surface of the T-shaped shaft rod 58. The bottom end of the bottom clamping rod 513 penetrates into one of the limiting clamping grooves 514, which can effectively limit the limiting baffle 59 in daily use, ensuring that the limiting baffle 59 can stably block and limit the limiting penetrating rod 55. A side groove 516 is provided on the side of the limiting baffle 59. A shifting block 517 is provided in the side groove 516. A connecting rod 515 is fixed to the bottom of the shifting block 517.The bottom end of the connecting rod 515 passes through the inner movable groove 510 and is fixedly connected to the inner movable block 512. If the length of the adjustable vertical plate assembly 5 is to be adjusted to change the height of the side pressure plate 7 in the later stage, it is only necessary to push the dial block 517 upward first, so that the connecting rod 515 moves up with the inner movable block 512, and the bottom end of the bottom clamping rod 513 moves out of the limit clamping groove 514, so that the limit on the limit baffle 59 can be released. At this time, the limit baffle 59 is rotated around the T-shaped shaft rod 58 so that the limit baffle 59 no longer blocks the side slot 57. At this time, the adjustable vertical plate assembly 5 can be directly withdrawn, and then the top plate 52 can be slid up and down to change the height of the side pressure plate 7. When the top plate 52 slides up and down, the inner slide plate 53 will also slide in the inner slide groove 54. When the side pressure plate 7 is adjusted to a suitable height, the limit baffle 59 is rotated again. The positioning rod 55 is inserted back so that the positioning rod 55 can be inserted into the through hole 56 at other positions through the side slot 57 and penetrate the through hole 56 until the two ends of the positioning rod 55 are respectively in the side slots 57 on both sides of the plate seat 51, so as to realize the support and limit of the inner slide plate 53 and complete the height adjustment of the side pressure plate 7. Finally, the shift block 517 is shifted and the positioning baffle 59 is rotated so that the positioning baffle 59 can cover and block the side slot 57 again. Then, the shift block 517 is released so that the spring 511 pushes the inner movable block 512 back to reset and the bottom clamping rod 513 can be clamped into the positioning clamping groove 514 at the initial position, so as to limit the positioning baffle 59 again, ensuring that the positioning baffle 59 stably blocks and limits the positioning rod 55 and ensures the stability of the side pressure plate 7 after the height adjustment.

[0019] A through hole is provided between the side slot 57 and the inner slide groove 54 , and the through hole corresponds to the limiting penetration rod 55 , so as to allow the limiting penetration rod 55 to pass through smoothly.

[0020] A vertical hole is provided between the side groove 516 and the inner movable groove 510 , and the vertical hole corresponds to the connecting rod 515 , so that the connecting rod 515 can pass through smoothly.

[0021] Among them, the piston rod at the bottom end of the cylinder A4 penetrates to the bottom of the top seat 3, and an upper pressure plate 8 is fixed on the piston rod at the bottom end of the cylinder A4. When the carton is actually glued, the carton is first placed on the conveyor belt 2 and conveyed forward, so that the carton is conveyed between the two side pressure plates 7 and is at the bottom of the gluing head 12. At this time, the cylinder B6 works to make the two side pressure plates 7 push the two folded edges at the top of the carton toward the center and close, and then the cylinder C9 works to make the gluing head 12 glue the folded edges of the carton. After gluing, the conveyor belt 2 continues to convey the carton to the bottom of the upper pressure plate 8. At this time, the cylinder A4 works to make the upper pressure plate 8 press the folded edges of the carton after gluing, and after maintaining for a period of time, the gluing operation of the carton is completed.

[0022] Example 2

[0023] See also Figures 1 to 3, which is the second embodiment of the utility model. This embodiment is based on the previous embodiment. The difference is that the rubber seat 518, the positioning protrusion 519 and the annular positioning groove 520 can be provided to play an auxiliary positioning effect when the limiting through rod 55 passes through the plate seat 51, thereby further improving the convenience of adjusting the length of the adjustable vertical plate assembly 5.

[0024] Specifically, the adjustable vertical plate assembly 5 also includes a rubber seat 518, a positioning protrusion 519 and an annular positioning groove 520. The upper inner wall of the side slot 57 is glued with a rubber seat 518, and the rubber seat 518 is located above the limiting rod 55. The bottom surface of the rubber seat 518 is provided with a positioning protrusion 519. Both end surfaces of the limiting rod 55 are provided with annular positioning grooves 520 corresponding to the positioning protrusion 519. The positioning protrusion 519 is embedded in the annular positioning groove 520, so that when the limiting rod 55 smoothly passes through the through hole 56 and is inserted into the inside of the side slot 57, the positioning protrusion 519 will be squeezed into the annular positioning groove 520. , thereby playing an auxiliary limiting role for the limiting penetration rod 55 at this time, ensuring that the limiting penetration rod 55 will not move horizontally by itself at this time, thereby facilitating the subsequent operator to rotate the limiting baffle 59 upward, and when the limiting penetration rod 55 is subsequently pulled out, the operator only needs to pull the limiting penetration rod 55 with force, and the positioning protrusion 519 will be squeezed again and squeezed out of the annular positioning groove 520, thereby realizing the smooth insertion and removal operation of the limiting penetration rod 55. At the same time, the design of the annular annular positioning groove 520 also makes it convenient for the subsequent operator to buckle the fingertips into the annular positioning groove 520 when removing and inserting the limiting penetration rod 55, thereby facilitating the application of force when removing and inserting the limiting penetration rod 55.

[0025] The rubber seat 518 is L-shaped, and the rubber seat 518 and the positioning protrusion 519 are an integrated structure. Both are made of rubber material and will undergo elastic deformation when squeezed.
