Cutter signal transmission device for automatic cutting bed

Abstract

The invention provides a cutter signal transmission device for an automatic cutting bed. The cutter signal transmission device comprises a cutter monitor, a signal acquisition device, a rotating insulation ring and a signal fixed transmission part. The cutter monitor moves with a rotor of a rotating mechanism in a synchronous mode, the signal acquisition device is immovable and is provided with a signal acquisition wire. The rotating insulation ring is fixedly connected with the rotor and is provided with a plurality of annular grooves at intervals in the axial direction, and a conductor coil communicated with a monitoring signal transmission wire of the cutter monitor. The signal fixed transmission part is fixed to the automatic cutting bed and fixedly provided with a conductor contact corresponding to the conductor coil in a one-to-one mode, one end of a conductor contact is contact connection with the conductor coil, and the other end is connected with the signal acquisition wire. According to the cutter signal transmission device for the automatic cutting bed, a monitoring signal is transmitted from the rotating monitoring signal transmission wire to the immovable signal acquisition wire, twisting and winding of the monitoring signal transmission wire are avoided, it is ensured that a cutter deviation control system adjusts the state and displacement of the cutter in time, and product quality is ensured.

Description

technical field [0001] The invention relates to the technical field of automatic cutting equipment, in particular to a cutting knife signal transmission device of an automatic cutting machine. Background technique [0002] The automatic cutting bed is used in the garment cutting process, using the computer-aided design setting data to control the movement direction of the cutter to produce the required pieces, and can automatically complete the whole process of board making, nesting, spreading and cutting . [0003] An automatic cutting bed is a complex system with a computer and corresponding programs. Its working principle is to fix the fabric in the bristle area after vacuum adsorption, and use the rotation of the cutter and the up and down reciprocating movement to cut. While cutting in large quantities, it can ensure the cutting accuracy of fabrics, and ensure the work efficiency and product quality of garment enterprises. [0004] The cutting executive mechanism of ...

AI Technical Summary

Problems solved by technology

For the case where the material to be cut has a high stacking height or the material of the material is relatively hard, the cutting knife is subjected to a greater resistance to feeding. Since the cutting knife is longer in length and thinner in thickness, it will be deformed to a certain extent, resulting in cutting When there is a size error between the upper and lower pieces, it will affect the cutting effect

Moreover, during the high-speed up-and-down reciprocating movement of the cutting knife, it will be impacted by various resultant forces, which will cause twisting or offset, and deviate from the originally set cutting track.

The above factors will seriously affect product quality, increase production costs, and reduce enterprise production efficiency

[0005] Therefore, it should be considered to set up a cutter deviation correction control system for real-time monitoring and control of the running track and deformation of the cutter, but the monitor for real-time monitoring of the cutter in the deviation correction control system is installed on the rotating mechanism (such as the rotating On the cutter head), the signal transmission wire of the monitor will be kinked and entangled with the rotation of the rotating mechanism, and the monitoring signal cannot be transmitted to the fixed control device to realize the normal transmission of the signal, and the cutting knife deviation correction control system cannot normal work
