Description

Technical Field

[0001] The invention relates to the field of corrugated paperboards, and in particular to a corrugated paperboard production and conveying system. Background Art

[0002] Corrugated cardboard is also called corrugated cardboard. Corrugated paper is made into a wave shape, and then one or two layers of cardboard are glued together to make corrugated cardboard. Corrugated cardboard has a certain hardness, can withstand a certain pressure from a flat surface, and is elastic and has a good cushioning effect. It can be made into pads or containers of various shapes and sizes as needed, which is simpler and faster than plastic cushioning materials. Therefore, it is widely used in the field of article packaging and is in great demand.

[0003] At present, the production and transportation of corrugated cardboard has a high degree of automation. The corrugated base paper enters the single-facer or double-facer machine, the longitudinal cutting device, the transverse cutting device, the stacking device, etc. from the base paper roll in sequence, and then is transported to the bundling device through the conveyor line for bundling, and is transported out after bundling. During bundling, in order to prevent the bundling belt from damaging the corrugated cardboard, an extra longer corrugated cardboard is usually placed on the corrugated cardboard stack as a buffer. However, setting up operators to place the buffer cardboard separately will lead to a waste of manpower and increase production costs. The use of mechanical devices for placement has the following difficulties: 1) The corrugated cardboard is relatively thin, how to take only a single piece of corrugated cardboard for buffering; 2) The corrugated cardboard stacks on the transportation line are of different heights, how to place the buffer cardboard on the corrugated cardboard stack, and how to accurately place the buffer cardboard during bundling. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a corrugated cardboard production and conveying system to solve the problem that the existing conveying system requires separate operators to place buffer cardboard, resulting in manpower waste and increased production costs.

[0005] To achieve the above-mentioned purpose, the present invention provides a corrugated cardboard production and conveying system, comprising a conveying device, and also comprising a cardboard stacking mechanism arranged on the side of the conveying device, the cardboard stacking mechanism is used to stack buffer cardboard and can drive it to move up and down; the cardboard stacking mechanism is provided with a transportation mechanism, and the transportation mechanism is used to transport the buffer cardboard in the cardboard stacking mechanism to the top of the conveying device; the conveying device is provided with a placement mechanism that can move up and down, and the placement mechanism is used to receive the buffer cardboard transported by the transportation mechanism, and can move downward to place the buffer cardboard above the corrugated cardboard stack.

[0006] The principle of the technical solution is as follows: the conveying device is used to transport the corrugated cardboard stack, and a bundling device is arranged at the rear of the conveying device. The bundling device is used to tighten the bundling belt and pack and bundle the corrugated cardboard stack, and the conveying device runs towards the bundling device; the bundling device is relatively existing and will not be described in detail below. The cardboard stacking mechanism is arranged on the side of the conveying device, and a longer buffer corrugated cardboard (hereinafter referred to as buffer cardboard) is placed inside. The cardboard stacking mechanism is used to lift the buffer cardboard upward. After the top buffer cardboard contacts the transport mechanism, the transport mechanism starts to push out the top buffer cardboard and move it to the placement mechanism located above the conveying device. The placement mechanism can assist in receiving the buffer cardboard and move downward to place the buffer cardboard on the corrugated cardboard stack. After the buffer cardboard is placed, the corrugated cardboard stack continues to move through the conveying device and is packed and bundled when passing under the bundling device.

[0007] Compared with the prior art, the beneficial effects of the present invention are: 1) The present invention can automatically place buffer cardboard on a corrugated cardboard stack, replacing manual placement, effectively reducing labor costs and saving costs.

[0008] 2) The present invention realizes the pushing out of a single buffer cardboard, thus avoiding waste caused by excessive buffer cardboard.

[0009] 3) The present invention places the buffer cardboard from top to bottom, which can be used for corrugated cardboard stacks of different heights.

[0010] 4) When the buffer cardboard is placed downward, the present invention can stably place it on the bundling position of the corrugated cardboard stack to avoid misalignment.
