Description

Technical Field

[0001] This utility model belongs to the technical field of honeycomb paperboard processing equipment, and specifically relates to a honeycomb paperboard creasing machine that facilitates the replacement of pressure rollers. Background Technology

[0002] When corrugated paper is processed, it needs to be shaped into a wave shape by a creasing machine so that it can be folded at the creasing points.

[0003] Currently, Chinese utility model patent CN216634544U discloses a die-cutting and creasing machine for corrugated paper, comprising: a mounting box, wherein a rubber pad is installed on the upper inner surface of the mounting box, a first connecting plate is connected to the left side of the lower end surface of the top plate, and a second connecting plate is connected to the right side of the lower end surface of the top plate; a motor, which is fixedly installed on the left end surface of the first connecting plate by bolts, and a first pressure roller is connected to the right end of the motor; a second pressure roller, which is disposed in front of the first pressure roller and is also connected between the first and second connecting plates; and a second fixing seat, which is fixedly installed on the lower front end of the mounting box, and a cutting assembly is disposed above the second fixing seat. This utility model provides a die-cutting and creasing machine for corrugated paper that facilitates the replacement of the creasing mechanism, thereby easily adjusting the creasing thickness, and also solves the problem that current die-cutting and creasing machines for corrugated paper are not convenient for cutting the facing paper.

[0004] In summary, while this creasing machine can achieve the goal of quickly changing the creasing mechanism, it still has certain problems in use. For example, the machine uses multiple pressure rollers, each with a different sized pressure wheel, allowing for quick replacement of the appropriate pressure wheel. However, each pressure roller requires a corresponding hydraulic lifting structure, resulting in higher production costs. Furthermore, the position of the pressure wheel on the pressure rollers cannot be adjusted, leading to a fixed distance between creasing marks. It can only creasing marks of a certain distance, making it unsuitable for other sizes and thus having poor applicability. Utility Model Content

[0005] The purpose of this invention is to provide a honeycomb paperboard creasing machine with easy-to-change pressure rollers, which has the advantages of easy replacement, low cost and strong applicability.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a honeycomb cardboard creasing machine that facilitates the replacement of pressure rollers, comprising a mounting frame, a support base symmetrically arranged on the top of the mounting frame, a rotating seat and a sleeve respectively rotatably connected at the center of the two support bases, a connecting column arranged inside the sleeve, a mounting plate fixedly sleeved on the opposite side of the connecting column and the rotating seat, a threaded mounting rod arranged between the two mounting plates, a locking mechanism arranged between the mounting plate and the threaded mounting rod, a plurality of sleeves threadedly connected to the surface of the threaded mounting rod, a pressure roller fixedly sleeved on the surface of the sleeve, and a plurality of limiting sleeves threadedly connected to the surface of the threaded mounting rod, and the limiting sleeves cooperate with the sleeves.

[0007] The above technical solution is as follows: A connecting column is installed inside the sleeve, and mounting plates are installed on both the connecting column and the rotating seat. When the connecting column moves and retracts into the sleeve, the two mounting plates no longer limit or fix the threaded mounting rod under the action of the locking mechanism. This allows workers to easily remove the threaded mounting rod from between the two mounting plates and replace it with a pressure roller equipped with a pressure roller of a different diameter. The structure is simple and low-cost. A sleeve threadedly connected to the threaded mounting rod is installed at the center of the pressure roller, and a limiting sleeve rotatably connected to the sleeve is also installed. When the worker rotates the pressure roller and the limiting sleeve simultaneously, the limiting sleeve and the pressure roller move synchronously on the threaded mounting rod, adjusting their position to suit different indentation distances, thus improving applicability.

[0008] The present invention is further configured such that one end of the sleeve is rotatably connected to an adjusting bolt, and one end of the adjusting bolt penetrates into the interior of the sleeve and is threadedly connected to the connecting column.

[0009] The above technical solution facilitates the adjustment of the connecting column's position inside the sleeve and limits the connecting column's movement.

[0010] The present invention is further configured such that the surface of the connecting column is symmetrically fitted with sliders, and the inside of the sleeve is provided with a sliding groove that is slidably connected to the sliders.

[0011] The above technical solution is adopted to slide and limit the movement of the connecting column inside the sleeve.

[0012] The present invention is further configured such that the locking mechanism includes locking blocks fixedly connected to both ends of the threaded mounting rod, and each of the two mounting discs has a locking groove on one side opposite to the locking block.

[0013] Using the above technical solution: when the card block is inserted into the card slot, the rotation of the two mounting discs can drive the threaded mounting rod to rotate, thereby limiting the rotation of the threaded mounting rod.

[0014] The present invention is further configured such that the mounting frame is symmetrically connected to a drive wheel via a rotating shaft inside, and a drive belt is connected between the two drive wheels. A drive motor fixedly connected to the rotating shaft of the drive wheel is mounted on the front of the mounting frame.

[0015] The above technical solution facilitates the conveying of honeycomb paperboard.

[0016] The present invention is further configured such that the top of the mounting bracket is symmetrically provided with mounting grooves that are slidably connected to the support base, and a hydraulic cylinder is embedded inside the mounting groove, the output end of the hydraulic cylinder being fixedly connected to the bottom of the support base.

[0017] The above technical solution facilitates the lifting and lowering of the support base on the mounting frame.

[0018] The present invention is further configured such that an annular limiting groove is provided on the side of the limiting sleeve near the sleeve, and an annular limiting block is mounted on the sleeve and slidably connected to the annular limiting groove.

[0019] The above technical solution is adopted to limit the rotation between the limiting sleeve and the sleeve.

[0020] In summary, this utility model has the following beneficial effects: 1. This utility model has a connecting column installed inside the sleeve, and mounting plates are installed on both the connecting column and the rotating seat. When the connecting column moves and retracts into the sleeve, the two mounting plates no longer limit and fix the threaded mounting rod under the action of the locking mechanism. This makes it convenient for workers to remove the threaded mounting rod from between the two mounting plates and replace it with a pressure roller equipped with pressure rollers of other diameters. The structure is simple and the cost is low. 2. This utility model has a sleeve installed at the center of the pressure roller that is threadedly connected to the threaded mounting rod. When the operator rotates the pressure roller and the limiting sleeve at the same time, the limiting sleeve and the pressure roller move synchronously on the threaded mounting rod, adjusting their position on the threaded mounting rod so that they can be used for pressing indentations at different distances, thus improving applicability.

By setting the adjusting bolt 12, the position of the connecting post 5 inside the sleeve 4 can be easily adjusted, and the connecting post 5 can be limited. Slider blocks 13 are symmetrically mounted on the surface of the connecting post 5. A sliding groove 14 is provided inside the sleeve 4 to slide with the slider 13. The slider 13 and the slide groove 14 provide sliding limit for the connecting column 5 when it moves inside the sleeve 4. The connecting column 5 and the rotating seat 3 are both fixedly sleeved with mounting plates 6 on opposite sides. A threaded mounting rod 7 is provided between the two mounting plates 6. A locking mechanism 8 is provided between the mounting plates 6 and the threaded mounting rod 7. The locking mechanism 8 includes locking blocks 81 fixedly connected to both ends of the threaded mounting rod 7. The two mounting plates 6 are both provided with locking grooves 82 that engage with the locking blocks 81 on opposite sides. By setting the locking blocks 81 and the locking grooves 82, when the locking blocks 81 are engaged in the locking grooves 82, the rotation of the two mounting plates 6 can drive the threaded mounting rod 7 to rotate, thereby limiting the rotation of the threaded mounting rod 7. The top of the mounting frame 1 is symmetrically provided with mounting grooves 18 that are slidably connected to the support seat 2. A hydraulic cylinder 19 is embedded inside the mounting groove 18. The output end of the hydraulic cylinder 19 is fixedly connected to the bottom of the support seat 2.

[0025] Brief description of the usage process: When it is necessary to disassemble the threaded mounting rod 7 during operation, simply rotate the adjusting bolt 12 to move the connecting column 5 into the sleeve 4. The connecting column 5 moves the mounting plate 6 installed on the connecting column 5 towards the support seat 2, so that the two mounting plates 6 have enough space for the locking block 81 of the threaded mounting rod 7 to disengage from the locking groove 82 of the mounting plate 6. After the locking block 81 and the locking groove 82 are disengaged, the threaded mounting rod 7 can be taken out from between the two mounting plates 6. The threaded mounting rod 7 can be installed by reversing the operation and replacing it with a threaded mounting rod 7 with a suitable diameter pressure roller 10.

[0026] Example 2: refer to Figure 1 , Figure 2 and Figure 5 A honeycomb cardboard creasing machine with easy-to-change pressure rollers includes a mounting frame 1. Support seats 2 are symmetrically arranged on the top of the mounting frame 1. Rotating seats 3 and sleeve seats 4 are rotatably connected to the centers of the two support seats 2, respectively.

A threaded mounting rod 7 is provided between the two mounting discs 6. A locking mechanism 8 is provided between the mounting discs 6 and the threaded mounting rod 7. Multiple sleeves 9 are threadedly connected to the surface of the threaded mounting rod 7. Pressure rollers 10 are fixedly fitted onto the surface of the sleeves 9. Multiple limiting sleeves 11 are threadedly connected to the surface of the threaded mounting rod 7, and the limiting sleeves 11 cooperate with the sleeves 9. An annular limiting groove 20 is opened on the side of the limiting sleeve 11 near the sleeve 9. An annular limiting block 21 is mounted on the sleeve 9 and slidably connected to the annular limiting groove 20. By setting the annular limiting groove 20 and the annular limiting block 21, rotational limitation is achieved between the limiting sleeve 11 and the sleeve 9.

[0027] Brief description of the usage process: When the operator rotates the pressure roller 10 and the limiting sleeve 11 at the same time, the limiting sleeve 11 and the pressure roller 10 move synchronously on the threaded mounting rod 7, adjusting their position on the threaded mounting rod 7. And through the action of the limiting sleeve 11, when the limiting sleeve 11 is not rotating on the threaded mounting rod 7, the sleeve 9 cannot rotate, thus improving the stability of the fixation.
