If there is enough space in the machine head, it can also be mounted on the die head bottom plate 200 of the machine head through a connecting block; the wiping mechanism 5 is movably arranged on the driving module 6 corresponding to the lip of the coating die 300 of the coating machine, and the wiping mechanism 5 can be driven by the driving module 6 to wipe back and forth along the length direction of the lip of the coating die 300 of the coating machine. The cleaning box 4 is arranged above one end of the driving module 6. Preferably, the cleaning box 4 is arranged above the starting end of the driving module 6 so that the wiping part of the wiping mechanism 5 can be cleaned when it returns. A cleaning chamber 41 that can accommodate the wiping part of the wiping mechanism 5 is provided in the cleaning box 4. A wiping mechanism inlet and outlet are provided on one side of the cleaning chamber 41. The cleaning box 4 is provided with a cleaning liquid inlet and a sewage outlet 42. The cleaning power group 2 is arranged on the cleaning liquid tank 1 and is connected to the cleaning liquid inlet of the cleaning box 4 through the cleaning pipe 3. The cleaning liquid in the cleaning liquid tank 1 is drawn by the cleaning power group 2 to clean the wiping mechanism 5 in the cleaning box 4 through the cleaning pipe 3.

[0036] Combination Figure 2 As shown, in this embodiment, the driving module 6 includes an upper guide rod 61, a rodless cylinder 62 and a lower guide rod 63, and the upper guide rod 61, the rodless cylinder 62 and the lower guide rod 63 are arranged in parallel from top to bottom; the wiping mechanism 5 includes a movable connecting seat 51, a wiping rod 52, a wiping head 53 and a wiping cotton 54, the wiping rod 52 is slidably connected to the upper guide rod 61 and the lower guide rod 63 through the movable connecting seat 51 and is transmission-connected to the rodless cylinder 62, the wiping head 53 is arranged on the wiping rod 52, and the wiping cotton 54 is arranged on the side of the wiping rod 52 facing the lip of the coating die 300, and the wiping head 53 and the wiping cotton 54 constitute a wiping part. The rodless cylinder 62 drives the wiping head 53 to move back and forth along the upper guide rod 61 and the lower guide rod 63, thereby achieving back and forth wiping along the length direction of the lip of the coating die 300 of the coater. Of course, a motor-driven belt or chain can also be used instead of the rodless cylinder 62 as the wiping power.

[0037] Preferably, the rodless cylinder 62 is provided with an induction switch, and the movable stroke position of the wiping head 53 is adjusted by the induction switch.

[0038] Preferably, the wiping head 53 is a wiping chuck to clamp the wiping cotton 54, and the wiping cotton 54 can be replaced with wiping cloth, wiping felt, wiping rubber, etc.

[0039] Combination Figure 3As shown, the cleaning liquid tank 1 is fixedly mounted on the coating machine wallboard 100 through a fixed structure 11 on one side. Of course, it can also be fixedly mounted in other positions according to needs. The cleaning power group 2 includes a cleaning motor 21 and a cleaning liquid pump 22. The motor shaft of the cleaning motor 21 is connected to the cleaning liquid pump 22 through a coupling 23. The cleaning liquid pump 22 is connected to the cleaning liquid inlet of the cleaning box 4 through a cleaning pipe 3. A cleaning nozzle 8 is inserted on the cleaning liquid inlet of the cleaning box 4. One end of the cleaning pipe 3 is connected to the cleaning liquid pump 22, and the other end of the cleaning pipe 3 is connected to the cleaning nozzle 8. The cleaning liquid tank 1, the cleaning motor 21, the cleaning liquid pump 22, the cleaning pipe 3, the cleaning nozzle 8, and the cleaning box 4 form a cleaning system. The cleaning liquid in the cleaning liquid tank 1 is extracted by the cleaning liquid pump 22 and then passes through the cleaning pipe 3 to the cleaning nozzle 8 to clean the wiping part in the cleaning box 4.

[0040] Its specific working principle is: when the coating die 300 needs to be wiped, the coating die 300 withdraws, and at this time the wiping head 53 wipes the lip of the coating die 300 back and forth under the drive of the rodless cylinder 62, and enters the cleaning box 4 to clean the wiping part once when returning. The number of wiping back and forth can be set, and the stroke position is adjusted by the induction switch of the rodless cylinder 62; when the lip of the coating die 300 is wiped and before entering the coating position for coating, the wiping part returns to the cleaning box 4 driven by the rodless cylinder 62, and the wiping head 53 will be cleaned again in the cleaning box 4 by the cleaning liquid; when coating, the wiping part returns to the cleaning box 4, and at this time it does not affect the coating action and adjustment of the coating die 300. The wiping and cleaning actions are performed by the device in conjunction with the coating machine, and can also be manually operated in conjunction with the coating machine, including the setting of the wiping times and the duration of cleaning. The amount of cleaning liquid press of the cleaning wiping mechanism can be freely adjusted and set according to requirements. The device has a simple structure, a small number of parts, reliable action, and excellent efficacy.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
