Description

Technical Field

[0001] This utility model relates to the field of slit extrusion coating technology, and in particular to an automatic cleaning system for coating lips. Background Technology

[0002] After coating, some slurry remains on the coating lip of the slit extrusion coating die. A wiping component of the cleaning system is needed to clean the coating lip. After wiping, the wiping component remains on one side of the coating lip. However, because the distance between the coating lip and the back roller is small during coating, the wiping component may be squeezed against the back roller. Patent CN220239017U discloses a coating lip cleaning device that uses a drive component and a moving component to solve this problem. However, this structure requires multiple drive components and is complex and costly, thus requiring further improvement. Utility Model Content

[0003] The purpose of this invention is to provide an automatic lip cleaning system to solve the problems mentioned in the background art.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] Example 1: As Figure 1-6 As shown, an automatic cleaning system for the coating lip of a coating die 200 is provided, comprising:

[0026] The guide rail assembly 1 includes a transverse guide rail 11 and two extension guide rails 12 fixed at the left and right ends of the transverse guide rail 11; the transverse guide rail 11 is used to be transversely fixed to the front side of the coating die head 200; the left extension guide rail 12 extends out of the left side of the coating die head 200; the right extension guide rail 12 extends out of the right side of the coating die head 200; one end of the extension guide rail 12 is connected to the end of the transverse guide rail 11, and the other end is bent to the rear.

[0027] Wiping component 3 is slidably connected to the front side of guide rail component 1;

[0028] Drive component 4 controls the wiping component 3 to slide within guide rail component 1.

[0029] After wiping stops, the wiping component 3 of this design stays at the end of one of the extended guide rails 12. Since the extended guide rail 12 extends to the outside of the coating die head 200, the wiping component 3 will not cause compression with the back roller when the coating die head 200 is working. When wiping is required, the drive component 4 can control the wiping component 3 to slide along the guide rail to wipe and clean the coating lip 201 of the coating die head 200.

[0030] In this design, the extension guide rail 12 is a 90° curved rail, including a first straight rail 121, an arc rail 122 and a second straight rail 123 connected in sequence; the end of the first straight rail 121 is connected to one end of the transverse rail. According to actual needs, the arc rail 122 can be set to different angles, generally 90°-120° is more suitable, and 90° is the best.

[0031] Sensors 13 are respectively provided at both ends of the guide rail assembly 1; the wiping assembly 3 includes a mounting plate 31, a slide 32, a wiping cotton 33, and two sensing pads 34; the mounting plate 31 is provided with a wiping cotton mounting part 311; the slide 32 is fixed to the rear side of the mounting plate 31 and slidably connected to the guide rail assembly 1; the wiping cotton 33 is fixed inside the wiping cotton mounting part 311 and extends out of the rear side of the mounting plate 31; the two sensing pads 34 are respectively fixed on the left and right sides of the mounting plate 31. When the sensor detects that the sensing pad 34 has entered, it sends a signal to the drive assembly 4 to control the drive assembly 4 to stop working.

[0032] The drive assembly 4 includes a first motor 41, a traction rope 42, a traction wheel 43, two guide wheels 44, and two reversing wheels 45. The two reversing wheels 45 are respectively fixed to the bottom of the two extended guide rails 12 away from the transverse guide rail 11 by reversing wheel connecting brackets. The two guide wheels 44 are respectively installed at the left and right ends of the front side of the coating die head 200. The guide wheels 44 have two guide grooves distributed vertically. The first motor 41 is installed on the left and right sides of the coating die head 200 and its power output end is connected to the traction wheel 43. The traction rope 42 is installed between the traction wheel 43, the two reversing wheels 45, and the two guide wheels 44. A connector is provided on the rear side of the mounting plate 31. The connector is fixedly connected to one side of the traction rope 42. In this embodiment, the drive assembly 4 is driven by the traction rope 42. The traction rope 42 is a rope with closed ends. The first motor 41 is installed on the left side of the coating die head 200. The traction rope 42 is installed on the traction wheel 43. Then, it passes through the left reversing wheel 45, the upper guide groove of the left guide wheel 44, the upper guide groove of the right guide wheel 44, the right reversing wheel 45, the lower guide groove of the right guide wheel 44, and the lower guide groove of the left guide wheel 44 in sequence before returning to the traction wheel 43. When the first motor 41 controls the traction wheel 43 to rotate, it can drive the traction rope 42 to run, thereby driving the mounting plate 31 connected to the traction rope 42 to move.

[0033] It also includes cleaning components 5; two sets of cleaning components 5 are respectively set at the left and right ends of the guide rail assembly 1; the cleaning components 5 include a water tank 51, a nozzle water pipe 52 and a water trough 53; the water trough 53 is set below the extension guide rail 12; the bottom of the water trough 53 is provided with a water outlet; the front side of the water trough 53 is provided with an inlet and outlet for the wiping component 3 to enter and exit; the inlet and outlet are provided with two soft water baffles 531 distributed on the left and right; one end of the nozzle water pipe 52 is connected to the water tank 51, and the other end extends into the water trough 53. The wiping component 3 enters the water trough 53 from the inlet and outlet through the soft water baffles 531. The water tank 51 has a water pump that supplies water to the nozzle water pipe 52. The nozzle water pipe 52 cleans the wiping cotton 33 of the wiping component 3 in the water trough 53, and the cleaned water falls from the water outlet.

[0034] Example 2: Figure 7-8 As shown, the difference from Embodiment 1 is that the driving method adopts a gear and rack drive. The driving assembly 4 includes a second motor 46, a gear 47, and a rack 48. The upper end of the mounting plate 31 is provided with a T-slot. The second motor 46 is fixed to the upper end of the mounting plate 31 and its power output end extends into the T-slot and is connected to the gear 47. The rack 48 is fixed to the front side of the transverse guide rail 11 and the extension guide rail 12. The gear 47 meshes with the rack 48, and the second motor 46 controls the gear 47 to rotate. The gear 47 meshes with the rack 48, thereby driving the mounting plate 31 to slide on the guide rail assembly 1.
