Description

Technical Field

[0001] The utility model belongs to the technical field of compaction devices, and particularly relates to a cardboard processing compaction device. Background Art

[0002] A cardboard processing compaction device generally refers to a mechanical device used to improve the density and strength of cardboard during the production process. This device makes the fibers in the cardboard material bind more closely together by applying pressure, thereby improving the flatness, thickness uniformity, and physical properties of the cardboard, such as compressive strength and stiffness. In the prior art, a support frame is usually arranged at the upper end of a fixed frame, a hydraulic rod is arranged at the lower end of the support frame, and a roller member is connected to the lower end of the hydraulic rod to compact the cardboard. However, in this method, the compaction device is not provided with a pre-arrangement component, and the cardboard cannot be squeezed and aligned towards the middle in advance. The cardboard may not be effectively combed and aligned before entering the compaction stage, resulting in uneven stacking. Then, during the compaction process, some areas may be over-compressed, while other areas may be under-compressed. This will cause uneven stress distribution inside the cardboard, increase the risk of damage, and affect the overall stability and strength.

[0003] For example, the utility model with the publication number CN220390488U discloses a compaction device for cardboard processing. In the technical solution of this patent, a support frame is arranged at the upper end of a fixed frame, a protective frame is fixedly connected to the upper surface of the support frame, and a roller is arranged on the lower surface of the protective frame. The roller is started to move downward to compact the cardboard. However, in this method, the compaction device does not have a pre-arrangement component for squeezing the cardboard towards the middle in advance, which may cause the cardboard to enter the compaction device in a disorderly direction and with different thicknesses, resulting in uneven stress during the compaction process. This will cause significant differences in the density and strength of the final product in different parts, affecting the use performance and appearance quality. Summary of the Utility Model

[0004] In view of this, in order to overcome the deficiencies of the prior art, the utility model provides a cardboard processing compaction device. The device can not only use a pre-arrangement component to make the extrusion plate move towards the middle, so as to squeeze and align the cardboard on the conveyor belt towards the middle, ensuring that the cardboard can be evenly pressed during the subsequent processing, but also adjust the length of the roller through a compaction component. Whether it is narrow-width or wide-width cardboard, appropriate pressing can be obtained, increasing the flexibility of the production line and the market adaptability.

[0005] To solve the above technical problems, the technical solution adopted by the present utility model is as follows: A cardboard processing and compaction device, including a mounting frame, inside which a conveying member is provided. The conveying member includes a driving roller rotatably arranged at the left end of the mounting frame, a driven roller rotatably arranged at the right end, and a conveyor belt is arranged on the outer surfaces of the driven roller and the driving roller. A pre-arrangement component is arranged at the upper left side of the mounting frame, and a compaction component is arranged in the middle of the mounting frame.

[0006] As a further improvement of the present utility model, the pre-arrangement component includes a first support frame arranged at the left end of the mounting frame.

The two ends of the first bidirectional lead screw are threadedly connected with first sliders. The lower ends of the first sliders are both connected with brackets. The ends of the brackets far away from the sliders are both connected with pressing plates.

[0007] As a further improvement of the present utility model, the compaction component includes a second support frame arranged in the middle of the mounting frame. A telescopic push rod is arranged at the upper end of the second support frame. The output end of the telescopic push rod passes through the upper side wall of the second support frame and is connected to a moving plate. A second chute is opened inside the moving plate. A second bidirectional lead screw is rotatably connected inside the second chute. A second motor connected to the second bidirectional lead screw is arranged at the front end of the moving plate. The two ends of the second bidirectional lead screw are threadedly connected with second sliders. The lower ends of the second sliders are both connected with support plates. A compaction member is detachably connected between the support plates. The compaction member includes a rotating column rotatably arranged on the two support plates. Flange plates are arranged on the opposite inner sides of the two rotating columns. A pressing roller is fixed between the two flange plates by bolts.

[0008] As a further improvement of the present utility model, a bearing plate is arranged in the middle of the inner wall of the conveyor belt.

[0009] As a further improvement of the present utility model, cushion plates are arranged on the inner side walls of the pressing plates.

[0022] As Figure 1 、 2 shown, the pre-arrangement assembly includes a first support frame 201 arranged at the left end of the mounting frame 101. A first chute is formed inside the first support frame 201. A bidirectional lead screw 202 is rotatably arranged inside the first chute. A driving member for driving the bidirectional lead screw 202 to rotate is arranged at the front end of the first support frame 201. The driving member includes a fixing frame 206 arranged at the front end of the first support frame 201. A first motor 207 is arranged at the left end of the fixing frame 206, and a worm 208 connected to the output end of the first motor 207 is connected to the right end. The front end of the bidirectional lead screw passes through the side wall of the first support frame 201 and is connected to a worm gear 209 meshing with the worm 208. Both ends of the bidirectional lead screw are threadedly connected with a first slider 203. Lower ends of the first sliders 203 are both connected with a support 204. One ends of the supports 204 away from the sliders are both connected with a pressing plate 205. By arranging the pre-arrangement assembly, starting the first motor 207 can make the bidirectional lead screw 202 rotate. The bidirectional lead screw 202 drives the first sliders 203 to approach or move away from each other, and then makes the supports 204 drive the pressing plates 205 to move towards the middle or both ends, so as to squeeze and regularize the cardboard on the conveyor belt 104 towards the middle, ensure that the cardboard can be evenly pressed during the subsequent processing, avoid uneven processing caused by position deviation or uneven stacking, thereby reducing the downtime for adjustment and improving the overall production efficiency.

[0023] As Figure 1 、 3As shown in the figure, the compaction component includes a second support frame 301 arranged in the middle of the mounting frame 101. The upper end of the second support frame 301 is provided with a telescopic push rod 302.

A detachable compaction member is connected between the support plates 307. The compaction member includes a rotating column 308 rotatably arranged on the two support plates 307. Flange plates 309 are arranged on the opposite inner sides of the two rotating columns 308. A pressure roller 310 is fixed between the two flange plates 309 by bolts. Starting the second motor 305 can make the second bidirectional lead screw 304 rotate.
