Description

Technical Field

[0001] The utility model relates to a corrugated paper pressing device. Background Art

[0002] Corrugated board is a multi-layer adhesive body, which is composed of at least one layer of corrugated core paper sandwich (commonly known as "corrugated paper", "corrugated board", "corrugated core paper", "corrugated paper core", "corrugated base paper") and one layer of cardboard (also known as "liner board", "liner"). It has high mechanical strength and can withstand collisions and drops during handling.

[0003] During the production of corrugated board, after slicing, it needs to be conveyed by a conveyor belt to the next trimming process to complete the trimming of the corrugated board.

[0004] During the high-speed operation of the conveyor belt, since the corrugated board is light in weight, it is easy to be blown up when passing through the surface of the conveyor belt at high speed, affecting the normal conveyance.

[0005] There are two traditional operation methods. One is to reduce the conveying speed of the conveyor belt, which will affect the production efficiency. The other is to use a pressing device.

[0006] The pressing device in the prior art is a large flat plate pressing down, and the pressing area is large. During the frequent pressing process, it will affect the normal conveyance of the corrugated board, causing intermittent conveyance of the corrugated board, and it is easy to cause the technical situation that two adjacent corrugated boards overlap, and it cannot be adjusted adaptively according to the thickness of the conveyed corrugated board.

[0007] Based on the above problems, we have designed a corrugated paper pressing device that can make the corrugated board convey smoothly on the surface of the conveyor belt and avoid the corrugated board from flying up. Content of the Utility Model

[0008] The technical problem to be solved by the utility model is to provide a corrugated paper pressing device that can make the corrugated board convey smoothly on the surface of the conveyor belt and avoid the corrugated board from flying up.

[0009] To solve the above problems, the utility model adopts the following technical solutions:

[0010] A corrugated paper pressing device includes a bracket system installed above the conveyor belt rack, and a pressing unit rotatably installed through the bracket system. There are multiple pressing units, and an acute angle is formed between the pressing unit and the conveyor belt.

[0011] Preferably, the bracket system includes two front and rear brackets, and a connecting rod fixed between the front and rear brackets. The connecting rod spans above the conveyor belt, and the pressing unit is rotatably installed with the connecting rod.

[0012] Preferably, the tablet pressing unit includes a swing plate. A through groove is longitudinally provided at the end face of the swing plate. A slider is arranged in the through groove. A chute communicating with the through groove penetrates through the top of the swing plate. A bolt is fitted through the chute. The bolt is screwed into the slider. After the bolt is tightened, the position of the slider is fixed. The connecting rod passes through the slider, and a bearing is provided between the connecting rod and the slider. One end of the swing plate is inclined downward, and a notch is provided at this end. A roller is rotatably arranged in the notch. The other end of the swing plate is inclined upward, and a center of gravity adjusting device is provided at this end.

[0013] Preferably, the center of gravity adjusting device includes a leveling rod with threads on its surface and a leveling nut for adjusting the position along the leveling rod. One end of the leveling rod is screwed into the swing plate.

[0014] Preferably, the other end of the leveling rod is provided with a polygonal force-bearing part.

[0015] The beneficial effects of the present utility model are as follows:

[0016] In this technical solution, the tablet pressing unit can swing to facilitate adapting to corrugated cardboard of different thicknesses. When the conveyor belt conveys the corrugated cardboard, the corrugated cardboard passes under the tablet pressing unit, avoiding the problem that the corrugated cardboard is blown up by the air flow, and at the same time not affecting the conveyance of the corrugated cardboard, which is suitable for popularization and use.
