Description

Technical Field

[0001] The invention relates to the technical field of paper box production equipment, in particular to a material clamping and feeding mechanism of an automatic folding box machine. Background Art

[0002] There are many existing paper box structures. However, since the paper box is three-dimensional, it will take up a large space during transportation, so that not many paper boxes can be placed in a unit volume, which is inconvenient to transport and increases transportation costs. In addition, during the movement of the box cardboard, if a reinforcing plate is placed on the cardboard, the stability of the movement of the cardboard and the reinforcing plate cannot be guaranteed.

[0003] Therefore, based on the above-mentioned defects of the existing paper boxes, it is necessary to improve the existing paper boxes. Summary of the invention

[0004] The object of the present invention is to provide a material clamping and feeding mechanism for an automatic folding box machine in view of the deficiencies in the prior art, which solves the defects of the existing paper boxes, such as the inability to ensure the stability of the movement of the paperboard.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions.

[0006] The material clamping and feeding mechanism of the automated folding box machine has an annular slide rail fixing plate vertically arranged below the frame, a driving motor is installed on the side of the annular slide rail fixing plate, an annular slide rail is installed on the outer side of the annular slide rail fixing plate, and an annular chain is installed on the inner side, the driving motor drives a sprocket, the sprocket drives the annular chain, a plurality of clamp mechanisms are installed on the annular chain, and the clamp mechanisms move along the annular slide rail; a roller matching plate is installed on the annular slide rail fixing plate, and the outer side edge of the roller matching plate has a slope, and the clamp mechanism changes its opening and closing state after passing through the slope position, and the clamp mechanism is moved by being controlled by the driving motor.

[0007] Furthermore, the clamp mechanism includes a clamp body, a first clamp arm is fixedly mounted on the clamp body, the first clamp arm is matched with a movable second clamp arm, a fixed block is provided next to the clamp body, a roller is pivotally provided on the fixed block, a connecting rod is connected between the lower part of the fixed plate and the second clamp arm, limit blocks are respectively installed on the upper and lower ends of the clamp body, the connecting rod passes through the limit blocks, a protrusion is provided on the connecting rod, a spring is sleeved on the connecting rod, and the spring is located between the protrusion and the lower end limit block.

[0008] Furthermore, the roller of the clamp mechanism is in active contact with the outer side of the roller matching plate, and the height position of the roller is changed by squeezing the outer side of the roller matching plate, so that the opening and closing state of the clamp mechanism is changed.

[0009] The beneficial effect of the present invention is that the clamp mechanism is driven to move by a driving motor so that the clamp mechanism can automatically open and close to clamp the cardboard and move, thereby realizing automated production, ensuring the positioning of the cardboard and the reinforcing plate, and preventing deviation during movement, thereby ensuring production quality.
