A servo-driven paper pressing brush device and its working method

Abstract

A servo-driven paper pressing brush device is characterized in that it includes a transmission belt, a servo motor, a rotating shaft, a paper pressing brush and a control system; the pressing paper brush is fixed on the rotating shaft, and the rotating shaft is installed on both sides On the frame, the rotating shaft can rotate around its axis; one end of the transmission belt is connected to the driving shaft of the servo motor, and the other end is connected to the rotating shaft. The power of the servo motor is transmitted to the rotating shaft through the transmission belt, thereby driving the paper pressing brush to swing up and down ; The servo motor is connected with the control system. The advantages of the present invention are: 1. The operation curve of the servo motor is set by programming, and the pressing time can be adjusted, and the adaptability is stronger; 2. The response speed of the servo motor is fast, and the pressing action of the pressing brush can be controlled in time; 3. The angle of paper pressing and the pressure of paper pressing can be adjusted according to the needs of different products.

Description

(1) Technical field: [0001] The invention is suitable for printing machines, especially for die-cutting and hot stamping equipment, and is a servo-driven pressing paper brush device and its working method. (two) background technology: [0002] The sheet-fed stripping die-cutting equipment uses the gripper bar to make the paper circulate in each process station, and completes a series of die-cutting and waste stripping actions. After all the processes are completed, the gripper bar will open at the set position Discard the waste paper, then turn back to the initial position to pick up another piece of paper, and start another cycle of the process station. [0003] In the waste edge conveying part, when performing the final action of opening the teeth and discarding the waste paper edge, there is generally a set of auxiliary paper pressing brush device. When the tooth row is opened, the waste paper edge is pressed by the brush to make the waste paper edge and Dental row detac...

AI Technical Summary

Problems solved by technology

The pressing paper brush of the prior art is driven by an air cylinder as disclosed in the patent CN103240766A. This method has disadvantages such as slow response speed and inability to adjust the pressing paper pressure in practical applications.
