Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paperboard processing, in particular to a pressing device. Background Art

[0002] Corrugated cardboard is a multi-layer adhesive body, which is composed of at least one layer of corrugated core paper and one layer of cardboard. It has high mechanical strength and can withstand collisions and falls during transportation. When producing and processing corrugated cardboard, it is necessary to use laminating equipment to press and fix multiple layers of cardboard into one body to make corrugated cardboard and improve the strength of corrugated cardboard. The existing laminating equipment for corrugated cardboard production on the market is old and cannot press corrugated cardboard of different thicknesses. It cannot adjust the spacing between rollers according to the thickness. The adjustment is very cumbersome and requires manual feeding and laminating, which is not only time-consuming and labor-intensive, but also has poor laminating effect.

[0003] In response to the above problem, a laminating device for corrugated cardboard production is disclosed in the Chinese patent announcement with announcement number CN212046189U, which includes a support frame, a first conveying roller and a second conveying roller are arranged in sequence from top to bottom on the left side of the support frame, a motor is fixedly installed in the middle position of the support frame, a first transmission wheel is movably installed at one end of the motor, and a transmission belt is movably connected to the first transmission wheel, a first conveying roller is movably installed at the upper end of the support frame, a second rotating wheel is fixedly installed at one end of the first conveying roller, a conveying belt is movably installed on the first conveying roller, a top plate is fixedly installed at the upper end of the support frame, a control switch is arranged at the upper end of the top plate, an electric hydraulic rod is fixedly installed at the lower end of the top plate, and a laminating roller is movably connected to one end of the electric hydraulic rod. The laminating device for corrugated cardboard production can provide stable feeding conditions, eliminate manual feeding, adjust the laminating thickness of corrugated cardboard, and improve the laminating quality of cardboard.

[0004] In actual operation, it is found that the above scheme still has at least the following defects: the method of using a conveyor belt to convey the multi-layer cardboard while using two pressing rollers to press and fix the multi-layer cardboard makes the pressing force applied to the cardboard by the pressing rollers for a short time, which easily causes the bonding time between the corrugated cardboards to be short, and there is a phenomenon that the pressing and fixing of the multi-layer cardboard is not tight and uniform, which affects the pressing quality of the corrugated cardboard. Therefore, we propose a pressing device to solve the above problems. Utility Model Content

[0034] Through the above structure, the laminating device provided by the utility model can press and fix multiple layers of cardboard tightly and evenly, thereby improving the laminating quality of corrugated cardboard. During specific operation, the multiple layers of cardboard for making corrugated cardboard that have been glued together are placed on the conveyor belt 6. By controlling the rotation of the conveying motor 7, the conveyor belt 6 can be controlled to transport the cardboard from right to left. When the left side of the cardboard is conveyed to the position directly below the anti-slip pressure pad 21, the operation of the conveying motor 7 is suspended at this time, and then the two electric hydraulic cylinders 9 are started to run synchronously, and the pressure seat 10 and the horizontal connecting seat 11 can be controlled to move vertically downward, so that when the anti-slip pressure pad 21 presses the left side of the cardboard, the two electric hydraulic cylinders 9 are stopped. At this time, the bottom of the pressure roller 16 also contacts the cardboard, and then the driving motor 18 is reversed, and the driving motor 18 drives the gear 19 to rotate counterclockwise (from the main view), and the meshing transmission effect of the gear 19 and the rack 20 can be used to control the movable seat 13 to drive the U-shaped frame 15 and the pressure roller 16 to move horizontally to the right. At this time, The pressing roller 16 can be used to press and fix the multi-layer cardboard evenly from left to right. By starting the driving motor 18 to rotate forward, the driving motor 18 drives the gear 19 to rotate clockwise (from the main view), and the meshing transmission effect of the gear 19 and the rack 20 can be used to control the movable seat 13 to drive the U-shaped frame 15 and the pressing roller 16 to move horizontally to the left. At this time, the pressing roller 16 can be used to press and fix the multi-layer cardboard evenly from right to left again. Then, by repeating the tight pressing and fixing operation in two directions for the cardboard for multiple times, the pressing quality of the corrugated cardboard can be improved. After the cardboard is pressed, when the pressing roller 16 moves to the leftmost position, the driving motor 18 is stopped, and then the two electric hydraulic cylinders 9 are controlled to reset so that the pressing seat 10 and the horizontal connecting seat 11 move vertically upward back to the original position, and then the conveying motor 7 is continued to be controlled to run, and the pressed corrugated cardboard can be continuously conveyed by the conveyor belt 6. According to the above operation steps, the next corrugated cardboard can be pressed.
