[0024] Example one:

[0025] The present embodiment is as follows Figure 1 and Figure 2As shown, a sand cloth joint laser edge grinding processing machine comprises a rack 1 and a belt conveyor 2 arranged on the rack 1. Along the advancing direction of the belt conveyor 2, a laser heat treatment device 3, a glue coating machine 4, a drying machine 5 and a fiber tape sticking machine 6 are sequentially arranged on the rack 1. The belt conveyor 2, the laser heat treatment device 3, the glue coating machine 4, the drying machine 5 and the fiber tape sticking machine 6 work coordinately under the control of a PLC controller 7.

[0026] Under the coordinated control of the PLC controller 7, the abrasive belt advances together with the belt conveyor 2 on the rack 1, passes through the high-temperature zone generated by the laser heat treatment device 3. In the case of the same conveying speed, the thicker the auxiliary material on the abrasive belt, the greater the required laser power coefficient, or the closer the laser source to the abrasive belt, so as to achieve the carbonization of the auxiliary material of a certain thickness on the abrasive belt. The carbonized auxiliary material is convenient for stripping in the later stage. Except for some residues that cannot be removed, the abrasive belt base cloth is as much as possible to be reserved. For example, in the case that the advancing speed is 9 m / min, the 36# zirconia alumina cloth base is treated at a high temperature of 800-1000°C (dissolution, gasification and carbonization) by the laser heat treatment device 3 to remove the excess auxiliary material (black in color) on the cloth base. The abrasive belt base cloth is maximally protected by accurately controlling the conveying speed and the thickness of the dissolved auxiliary material on the abrasive belt, and only the auxiliary material (glue and filler) is carbonized. The auxiliary material is carbonized and then separated from the abrasive cloth base cloth. Then, the carbonized auxiliary material (brittle and broken into powder) on the abrasive belt is cleaned by manual or existing cleaning equipment (such as a roller brush or a wire brush). The abrasive belt is prepared for glue coating. At this time, when passing through the glue coating machine 4, the glue is coated on the auxiliary material cleaning position of the abrasive belt. Then, the abrasive belt is dried by the drying machine 5. Finally, the fiber tape is stuck to the glue coating position of the abrasive belt by the fiber tape sticking machine 6, and the sand cloth joint processing work is completed. The device adopts the laser thickness carbonization method to remove the excess auxiliary material of the abrasive cloth, so as to solve the problems of uneven sand particles, different thicknesses of cloth bases and poor auxiliary material flatness in the traditional equipment. The device does not need to be frequently adjusted in the case of the same base material, improves the production efficiency, ensures the product quality, and the production method of the device is scientific and reliable. The quality is controllable, stable and balanced. The processed sand cloth joint has high strength, beautiful appearance and joint tension of 220-280 kg.

[0027] Preferably, a cleaning station is arranged between the laser heat treatment device 3 and the glue coating machine 4.

[0028] The worker can hold a brush to clean the abrasive belt after the laser high-temperature treatment at the cleaning station, or use existing cleaning equipment (such as an electric roller brush or an electric wire roller brush) at the cleaning station to clean the carbonized auxiliary material on the abrasive belt, so as to prepare for the later glue coating.

[0029] Preferably, a dust collector is arranged on the cleaning station.

[0030] The dust collector is an industrial dust collector, which can collect a small amount of dust generated when cleaning carbonized auxiliary materials on the abrasive belt, and prevent dust raising.

[0031] Preferably, the laser heat treatment device 3 is a fiber laser, and a working end of the fiber laser faces the working surface of the abrasive cloth.

[0032] Preferably, the gluing machine 4 is a roller type gluing machine.

[0033] Preferably, the drying machine 5 is a hot air machine, and a blowing end of the hot air machine faces the gluing surface of the abrasive cloth.

[0034] Preferably, the fiber tape applicator 6 is a film laminating machine.

[0035] The fiber tape (a sand belt butt joint tape, a sand belt flat joint tape, a sand belt joint tape, or a connection tape) is wound on the roll frame of the film laminating machine and applied to the gluing part of the sand belt.

[0036] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
