[0030] The support body 1 is internally provided with a gear box, and a motor is installed between the two support bodies 1. The gear box is respectively meshed and drivingly connected with the conveying shaft 4, the rolling roller 8 and the laminating roller 9. The support body 1 is internally provided with a gear box, and the motor is mechanically drivingly connected with the conveying shaft 4, the rolling roller 8 and the laminating roller 9 through the gear box. After the motor is powered on, the gear box inside the support body 1 is driven to operate. The gear box drives the conveying roller 13, the conveying shaft 4, the rolling roller 8 and the laminating roller 9 to synchronously rotate. The rotating directions of the conveying roller 13, the rolling roller 8 and the laminating roller 9 are consistent (counterclockwise rotating direction). The rotating directions of the conveying shaft 4, the conveying wheel 5 and the cutter 6 are consistent (clockwise rotating direction). The conveying wheel 5 rotates in opposite directions with the adjacent rolling roller 8 and the laminating roller 9 to give the label paper a frictional force for moving.

This transmission mode can provide stable and reliable power transmission, ensure the cooperative work of each part, ensure the stability and efficiency of the operation of the glue dispensing machine cutter 6 control device, has the characteristics of reliable power transmission, and reduces the dependence of the device on the power device of the glue dispensing machine.

[0031] The photoelectric switch 18 emits infrared radiation downward to the surface of the label paper. Due to the color difference between the cutting part and other parts of the label paper, the infrared reflection effect is different, and the infrared received by the photoelectric switch 18 is different from the originally emitted infrared. These differences in infrared signals are fed back to the PLC, which can make the photoelectric switch 18 identify the position of the label paper that needs to be cut. The PLC changes the rotating speed of the cutter 6, and relies on the PLC to control the rotating speed of the cutter 6 to change the cutting speed, so that the action of the cutter 6 changes. The PLC calculates the speed at which the photoelectric switch 18 senses the movement of the label paper. The power input end of the rotary encoder 12 is connected with a detection wheel through mechanical transmission. The first left-to-right adhering roller 9 is closely attached to the circumference of the detection wheel.

The rotary encoder 12 and the first left-to-right rotating roller 8 are connected in a rolling manner to transmit rotary force. There is rolling friction between the rotary encoder 12 and the first left-to-right rotating roller 8. When the first left-to-right rotating roller 8 rotates, it drives the rotary encoder 12 to rotate (similar to gear meshing transmission). When the first left-to-right rotating roller 8 rotates, it drives the wheel of the rotary encoder 12 to rotate. The rotary encoder 12 converts the signal of the first left-to-right rotating roller 8 into an electrical signal and feeds it back to the PLC. The rotary encoder 12 monitors the speed of the first left-to-right rotating roller 8, so that the PLC controls the speed of the transmission shaft 4 (the PLC changes the speed of the motor to achieve the effect of speed regulation), so that the cutter 6 can cut the label paper at the position that needs to be cut when rotating, ensuring the accuracy of the label paper during transmission. The cutter 6 is installed on a specific transmission shaft 4, and a cutting groove 11 and an adhering roller 9 are arranged at the corresponding position to form a cutting structure. The adhering roller 9 and the rotary encoder 12 are connected in a rolling manner to realize rolling friction transmission. The rotary encoder 12 can accurately monitor the rotation of the adhering roller 9 and then feed back the length and position information of the label paper in real time. When the label paper is conveyed to the appropriate position, the photoelectric switch 18 triggers, and the cutter 6 performs the cutting action. The distance between the upper end of the supporting plate 7 and the cutting edge of the cutter 6 is less than one millimeter. The width of the cutter 6 is equal to the height between the center of the transmission shaft 4 and the supporting plate 7, so that the cutter 6 is aligned with the position on the label paper that needs to be cut, realizing the control of the cutting position and length, and having high cutting accuracy and easy cutting. It is easy to cut in place, and the size of the label paper after cutting meets the use requirements, improves the accuracy and consistency of cutting, reduces the waste of label paper, has the characteristics of cutting control, and can cut the label paper after the glue dispenser dispenses glue into the appropriate size.
