Corrugated paperboard press-trimming machine

Abstract

The invention discloses a corrugated paperboard press-trimming machine and belongs to the field of paperboard manufacturing. The corrugated paperboard press-trimming machine comprises a machine frame, a hydraulic cylinder, an upper layer plate and a lower layer plate. The hydraulic cylinder is fixed to the top of the machine frame. The output end of the hydraulic cylinder is connected with the upper layer plate and drives the upper layer plate to move up and down along the machine frame. The lower layer plate is installed on the lower portion of the machine frame. The output end of the hydraulic cylinder is connected with the upper layer plate through a connecting rod. The connecting rod comprises a cross bar and a vertical bar, wherein the cross bar and the vertical bar are fixedly connected with each other. The cross bar is connected with the output end of the hydraulic cylinder. The vertical bar is connected with the upper layer plate. A sliding groove allowing the cross bar to move up and down therein is formed in the machine frame. The cross bar is arranged in the sliding groove. According to the corrugated paperboard press-trimming machine, the situations that a gap is formed between the hydraulic cylinder and the upper layer plate in the long-term operation process, shaking is generated, and movement deviation of the upper layer plate is caused can be prevented, so that it is guaranteed that the upper layer plate moves normally all the time, and the press-trimming effect is improved. Elastic layers are laid on the lower surface of the upper layer plate and the upper surface of the lower layer plate, so that the surfaces of a corrugated paperboard are fully press-trimmed and bonded, and the bonding effect and the strength of the corrugated paperboard are improved.

Description

technical field [0001] The invention relates to a cardboard pressing machine, in particular to a corrugated cardboard pressing machine, which belongs to the field of cardboard manufacturing. Background technique [0002] Corrugated cardboard, also known as corrugated cardboard, is made of at least one layer of corrugated paper and one layer of cardboard paper, and has good elasticity and extensibility. It is mainly used in the manufacture of cartons, the sandwich of cartons and other packaging materials for fragile goods. The common corrugated cardboard is made of native straw pulp and waste paper, which is made into a base cardboard similar to yellow cardboard, and then machined to make it into a corrugated shape, and then glued to the surface of the cardboard with an adhesive such as sodium silicate. . [0003] In the bonding process of corrugated cardboard production, corrugated cardboard compacting machines are usually required for compacting. The existing compacting m...

Problems solved by technology

[0003] In the bonding process of corrugated cardboard production, corrugated cardboard compacting machines are usually required for compacting. The existing compacting machines are all pressed by the opposite movement of the upper and lower pressing plates. The upper pressing plate is connected to the hydraulic cylinder, and the hydraulic cylinder Control the up and down movement of the upper platen. During the long-term operation of the press machine and the upper platen, gaps and shaking are likely to occur, and the operation of the upper platen will deviate, which will affect the corrugated cardboard pressing effect and reduce the qualified rate of finished products.
