It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0018] As Figures 1 to 3 shown, the present utility model discloses a pressing wheel adjusting device for a pressing and pasting box machine, which includes a frame 1. Inside the frame 1, there is a conveyor belt 2 for conveying cardboard. Above the conveyor belt 2, there are symmetrically arranged adjusting rods 3. The adjusting rods 3 are provided with locking holes 31. The locking holes 31 are multiple and spaced from each other. The adjusting rods 3 are sleeved with sliders 4. Between the two sliders 4, there is a connecting seat 5. The connecting seat 5 is connected to the bottom of the slider 4. At the bottom of the connecting seat 5, there is a pressing wheel 6. The pressing wheel 6 is rotatably connected to the connecting seat 5. The pressing wheels 6 are multiple and spaced from each other. The slider 4 is provided with a quick connection mechanism, which is used to quickly fix and release between the slider 4 and the locking hole 31. When it is necessary to adjust the position of the pressing wheel 6 to adapt to different specifications of cardboard, by sliding the slider 4, after sliding the connecting seat 5 connected to the slider 4 to a suitable position, the quick connection mechanism can quickly fix between the slider 4 and the locking hole 31. Thus, compared with the prior art method of fixing by rotating the locking bolt, the fixing efficiency can be improved, and further, the adjustment of the position of the pressing wheel 6 can be made more convenient and rapid;

[0019] Among them, the structure of the quick connection mechanism that can quickly fix the slider 4 and the lock hole 31 is as follows: there is a jack 41 on the slider 4 that can be opposite to the lock hole 31. The quick connection mechanism includes a guide seat 71 and a lock rod 72. The guide seat 71 is fixed to the slider 4. There is a guide cavity 711 in the guide seat 71. The guide cavity 711 is communicated with the jack 41. One end of the lock rod 72 extends into the guide cavity 711, and one end extends outside the guide cavity 711 as a connection end. A handle 721 is fixed to the connection end. A connection flange 73 is sleeved and fixed on one side of the lock rod 72 located in the guide cavity 711. The outer wall of the connection flange 73 abuts against the inner wall of the guide seat 71, so as to prevent the connection flange 73 from shifting when moving in the guide cavity 711. There is a first spring 74 in the guide cavity 711. One end of the first spring 74 is fixed to the connection flange 73, and one end is fixed to the inner wall of the guide seat 71 near the handle 721. Therefore, when it is necessary to slide the slider 4, first pull the lock rod 72 outward through the handle 721, so that the lock rod 72 is disengaged from the lock hole 31. At this time, the slider 4 can be slid. After the slider 4 is slid to the appropriate position, release the lock rod 72. Since the connection flange 73 can squeeze the first spring 74 along with the lock rod 72 during the process of pulling the lock rod 72 outward, the acting force generated by the deformation of the first spring 74 at this time can drive the lock rod 72 to be inserted back into the corresponding lock hole 31 after the lock rod 72 is released, so as to realize the fixation of the slider 4. Therefore, in this solution, only by inserting and pulling out the lock rod 72, the quick disassembly and assembly of the slider 4 and the adjusting rod 3 can be realized, so that the adjustment of the position of the pressure wheel 6 can be made more convenient and fast.

[0020] In this embodiment, adjusting seats 8 are further provided on both sides of the connection seat 5. There is an adjusting lead screw 9 rotatably connected in the vertical direction on the frame 1. The center of the adjusting seat 8 is sleeved on the outer periphery of the adjusting lead screw 9 and can form a threaded fit between the two. The adjusting rod 3 is fixed to the inner side of the adjusting seat 8. An adjusting handwheel 91 is provided at the end of the adjusting lead screw 9 away from the frame 1. The adjusting handwheel 91 is used to drive the adjusting lead screw 9 to rotate, so that the adjusting seat 8 moves in the vertical direction. Through the setting of the adjusting lead screw 9, the adjusting lead screw 9 can be driven to rotate by the adjusting handwheel 91 to drive the adjusting seat 8 to move in the vertical direction. And since the adjusting rod 3 is fixed to the inner side of the adjusting seat 8, the pressure wheel 6 can be driven to move in the vertical direction, so that the pressure wheel 6 can adapt to cardboard of different thicknesses, further expanding the scope of application.

[0021] In this embodiment, guide rods 10 are further provided on both sides of the adjusting lead screw 9 and are arranged vertically. Both ends of the adjusting seat 8 are sleeved on the guide rods 10, and a sliding fit can be formed between the two. When the adjusting lead screw 9 is rotated to enable the adjusting seat 8 sleeved on the outer periphery of the adjusting lead screw 9 and in threaded fit with the adjusting lead screw 9 to move along the direction of the adjusting lead screw 9, the arrangement of the guide rods 10 can play a guiding role in the movement of the adjusting seat 8, avoiding the rotation of the adjusting seat 8 along with the rotation of the adjusting lead screw 9 to ensure the stability of the movement of the adjusting seat 8.

[0022] In this embodiment, the specific connection structure between the connecting seat 5 and the slider 4 is that a connecting rod 11 is fixed at the bottom of the slider 4. A cavity 111 is provided in the connecting rod 11. A slidable sliding rod 12 is provided in the cavity 111. The end of the sliding rod 12 on the side far from the connecting rod 11 is fixed to the connecting seat 5. A second spring 13 is provided between the connecting seat 5 and the connecting rod 11. One end of the second spring 13 is fixed to the connecting seat 5, and the other end is fixed to the end of the connecting rod 11. Thus, when the cardboard is conveyed by the conveyor belt 2, after the cardboard passes through the pressing wheel 6, it can push the connecting seat 5 upward, enabling the connecting rod 11 to slide into the cavity 111, thereby squeezing the second spring 13. The acting force generated by the deformation of the second spring 13 can act on the cardboard through the pressing wheel 6, so as to ensure that the pressing wheel 6 has sufficient pressing force on the cardboard.

[0023] This specific embodiment is only an interpretation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications to this embodiment without creative contributions according to needs after reading this specification, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
