Description

A semi-automatic die-cutting machine

technical field

This application relates to the field of boxboard cutting, more specifically, it relates to a semi-automatic die-cutting machine.

Background technique

The use of cardboard is becoming more and more widespread. Many products are packaged in cardboard during the sales process. The manufacturing cost of cardboard is low. After packaging, it can effectively protect the product, and at the same time facilitate transportation and storage. It is well received by manufacturers and consumers. favorite. During the processing of boxboard, it is necessary to cut the formed boxboard according to certain size requirements, so as to facilitate the processing of boxboard.

In the process of cutting the boxboard, the conveyor belt drives the boxboard to move, and the cutting tool cuts the boxboard. When the knife cuts the boxboard, the conveyor belt stops moving. At this time, the motor driving the conveyor belt needs to stop. After cutting the boxboard, the motor restarts and drives. When cutting repeatedly, the frequency of motor shutdown and startup is high, which affects the service life of the motor.

Contents of the invention

In order to reduce the repeated opening and closing of the motor driving the conveyor belt, the application provides a semi-automatic die-cutting machine.

A kind of semi-automatic die-cutting machine provided by the application adopts the following technical scheme:

The conveyor belt includes a rotating roller, and the rotating roller is coaxially connected with a fixed plate. The rod slide has a sliding plate, and the sliding direction of the sliding plate is the length direction of the sliding rod. The elastic force of the sliding plate makes the sliding plate press against the driving rod; when the driving member drives the moving frame to move down, the cutter moves toward the direction close to the conveyor belt, and the partition plate makes the sliding plate slide away from the driving rod.

Through the above technical scheme, when the sliding plate presses against the driving rod, the driving rod drives the sliding plate to rotate to control the rotation of the roller, and when the driving part drives the cutter to move towards the direction of the conveyor belt, the sliding plate and the driving The rod is separated, so that the roller stops rotating; when the driving part drives the knife to move away from the conveyor belt, the spring is pressed so that the sliding plate is pressed against the driving rod, and the roller rotates again; thus, it is not necessary to repeatedly start and close the drive motor, so that the drive The motor can run normally and extend the life of the drive motor.

Further, the driving rod is provided with a driving plate, the driving plate is located at one end of the driving rod close to the sliding plate, the cross-sectional area of the driving plate in the vertical direction is larger than the vertical cross-sectional area of the driving rod, and the elastic force of the pressing spring makes the sliding plate close The drive plate thus bears against the drive rod.

Through the above technical solution, the driving plate is provided, and the area of contact between the driving plate and the sliding plate is increased, so that when the driving plate and the sliding plate are pressed against each other, it is easier to drive the sliding plate and the roller to rotate.

Further, an insert is provided at the end of the driving plate close to the sliding plate, and an insert hole is provided at the end of the sliding plate close to the driving plate, and the insert hole is used for inserting the insert.

Through the above technical solution, the inserts and the insert holes are provided, and the inserts are embedded in the insert holes.
