Description

Technical Field

[0001] This utility model relates to the field of coating machine accessories, and in particular to a gear-driven coating die head wiping assembly and cleaning device. Background Technology

[0002] The coating die head is formed by an upper die head and a lower die head clamping a gasket. The upper and lower die heads clamp together to form a protruding coating lip structure. A feed port is set on the back side of the lower die head, and a cavity is set on the top of the lower die head. The slurry flows from the feed port through the cavity and is extruded from the coating lip to be coated onto the substrate. During the debugging or coating process, some of the slurry extruded from the coating die head will not be transferred to the substrate and will remain at the coating lip. It will dry and affect the next coating. Therefore, a wiping component is required to move back and forth on the coating lip to clean it.

[0003] For example, patent CN220239017U discloses a coating lip cleaning device. Existing wiping components generally use a motor to drive a traction wheel for winding and unwinding, thereby controlling the movement of the traction rope and driving the wiping component to reciprocate on the coating die head to clean the coating lip. However, the traction rope itself has a certain elasticity, and the positional accuracy of driving the wiping component is not high. The wiping force of the wiping component on the coating lip is also difficult to control at different positions on the coating die head, negatively impacting the cleaning effect. Therefore, it is necessary to develop a gear-driven coating die head wiping component and cleaning device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a gear-driven coating die head wiping assembly and cleaning device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A gear-driven coating die head wiping assembly includes a guide rail, a slider, a mounting bracket, a stepper motor, a drive gear, a transmission gear, an elastic circular plate, and a wiping component. The guide rail is fixed to the coating die head, the slider is slidably connected to the guide rail, the mounting bracket is fixed to the slider, the stepper motor is fixed to the mounting bracket, the drive gear is fixed to the power output end of the stepper motor, the transmission gear is rotatably mounted on the mounting bracket and meshes with the drive gear, the elastic circular plate is fixed to the transmission gear and its outer periphery abuts against the surface of the coating die head, and the wiping component is mounted on the mounting bracket and its wiping end abuts against the coating lip.

[0007] Further description of the present invention: The wiping component includes a wiping head, a clamping spring, and a fixing screw. The mounting bracket has a mounting hole. The front end of the wiping head corresponds to the mounting hole, and the rear end abuts against the coating lip. The clamping spring is fixed to the mounting bracket by the fixing screw, and its elastic end is fixedly connected to the outer end face of the wiping head.

[0008] Further description of the present invention: The wiping head includes a soft rubber and a lint-free cloth, the front end of the soft rubber corresponds to the mounting hole, and the lint-free cloth is wrapped around the rear end of the soft rubber.

[0009] A gear-driven coating die head cleaning device includes a wiping assembly, a coating die head, and a cleaning assembly. The coating die head includes an upper die head and a lower die head, with a gap between them. The front end of the gap is a coating lip. A guide rail is fixed to the front end of the upper die head. The cleaning assembly includes a mounting plate, a cleaning chamber, a liquid supply component, a drive component, a connecting plate, and a connecting rail. The mounting plate is fixed to the end of the upper die head, the cleaning chamber is fixed to the mounting plate, the liquid outlet of the liquid supply component passes through the cleaning chamber, the drive component is fixed to the mounting plate, and the connecting plate is fixed to the power output end of the drive component and corresponds to the upper part of the cleaning chamber. The lower end of the connecting plate is provided with a connecting boss, and the connecting rail is fixed to the connecting plate and corresponds to the upper part of the connecting boss. When the drive component drives the connecting plate to move forward, the connecting rail and the connecting boss are respectively connected to the guide rail and the front end face of the upper die head.

[0010] Further description of this utility model: Two sets of cleaning components are provided and symmetrically arranged on the left and right sides of the coating die head.

[0011] Further description of the present invention: The cleaning chamber includes a chamber body, a chamber door, a rotating shaft, an elastic element, a drive plate, and a cylinder. The chamber body is fixed on a mounting plate and has an opening on the front side. The rotating shaft is rotatably mounted on the lower side of the chamber body. The lower end of the chamber door is fixed on the rotating shaft. The two sets of elastic ends of the elastic element are respectively fixedly connected to the chamber body and the chamber door.

[0012] Further description of the present invention: The bottom front side of the tank body is provided with an inclined flow guide slope, and the bottom of the tank body is also provided with a liquid outlet corresponding to the rear side of the flow guide slope.

[0013] The beneficial effects of this invention are as follows: The guide rail is mounted on the coating die head. A stepper motor drives the drive gear to rotate forward or backward, thereby driving the transmission gear and the elastic disc to rotate. Because the outer circumference of the elastic disc contacts the surface of the coating die head, the elastic disc can roll on the coating die head, allowing the mounting bracket to slide on the guide rail via a slider. The wiping component on the mounting bracket then wipes and cleans the coating lip. The advantages of this design are: it abandons the traditional traction rope method and adopts gear traction, avoiding problems caused by changes in traction rope length and improving transmission stability; the use of a stepper motor enables more precise displacement control, ensuring the accuracy of the wiping component's position during each cleaning, thus improving cleaning quality.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1 to 5 As shown, a gear-driven coating die head wiping assembly 1 includes a guide rail 11, a slider 12, a mounting frame 13, a stepper motor 14, a drive gear 15, a transmission gear 16, an elastic circular plate 17, and a wiping component 18. The guide rail 11 is fixed on the coating die head 2, the slider 12 is slidably connected to the guide rail 11, the mounting frame 13 is fixed on the slider 12, the stepper motor 14 is fixed on the mounting frame 13, the drive gear 15 is fixed on the power output end of the stepper motor 14, the transmission gear 16 is rotatably mounted on the mounting frame 13 and meshes with the drive gear 15, the elastic circular plate 17 is fixed on the transmission gear 16 and its outer periphery abuts against the surface of the coating die head 2, and the wiping component 18 is mounted on the mounting frame 13 and its wiping end abuts against the coating lip.

[0027] The guide rail 11 is mounted on the coating die head 2. A stepper motor 14 drives the drive gear 15 to rotate forward or backward, thereby driving the transmission gear 16 and the elastic circular plate 17 to rotate. Because the outer circumference of the elastic circular plate 17 contacts the surface of the coating die head 2, the elastic circular plate 17 can roll on the coating die head 2, allowing the mounting frame 13 to slide on the guide rail 11 via the slider 12. The wiping component 18 on the mounting frame 13 then wipes and cleans the coating lip. The advantages of this design are: it abandons the traditional traction rope method and adopts gear traction, avoiding problems caused by changes in traction rope length and improving transmission stability; the use of a stepper motor 14 enables more precise displacement control, ensuring the accuracy of the wiping component 18's position during each cleaning, thus improving cleaning quality.

[0028] The wiping component 18 includes a wiping head 181, a clamping spring 182, and a fixing screw 183. The mounting bracket 13 has a mounting hole 131. The front end of the wiping head 181 corresponds to the mounting hole 131, and the rear end abuts against the coating lip. The clamping spring 182 is fixed to the mounting bracket 13 by the fixing screw 183, and its elastic end is fixedly connected to the outer end face of the wiping head 181.

[0029] When wiping the coating lip, the clamping spring 182 applies a certain pressure to the wiping head 181, so that the wiping head 181 fits tightly against the coating lip, improving the quality and efficiency of cleaning the coating lip. The clamping spring 182 and the wiping head 181 can be easily disassembled and replaced by the fixing screw 183.

[0030] The wiping head 181 includes a soft rubber and a lint-free cloth. The front end of the soft rubber corresponds to the mounting hole 131, and the lint-free cloth is wrapped around the rear end of the soft rubber.

[0031] Since ordinary wiping cotton is easily torn and leaves cotton residue at the coating lip, this design uses a combination of shaped soft rubber and lint-free cloth to replace the wiping cotton, in order to ensure cleaning effect and normal operation of coating head 2.

[0032] A gear-driven coating die head cleaning device includes a wiping assembly 1, a coating die head 2, and a cleaning assembly 3. The coating die head 2 includes an upper die head 21 and a lower die head 22, with a gap between them. The front end of the gap is a coating lip. A guide rail 11 is fixed to the front end of the upper die head. The cleaning assembly 3 includes a mounting plate 31, a cleaning chamber 32, a liquid supply component 33, a driving component 34, a connecting plate 35, and a connecting rail 36. The mounting plate 31 is fixed to the end of the upper die head 21, and the cleaning chamber 32 is fixed to the mounting plate 36. On plate 31, the liquid outlet of liquid supply component 33 passes through the cleaning chamber 32. Drive component 34 is fixed on mounting plate 31. Connecting plate 35 is fixed on the power output end of drive component 34 and corresponds to the top of cleaning chamber 32. Connecting boss 351 is provided at the lower end of connecting plate 35. Connecting track 36 is fixed on connecting plate 35 and corresponds to the top of connecting boss 351. When drive component 34 drives connecting plate 35 to move forward, connecting track 36 and connecting boss 351 are connected to guide rail 11 and front end face of upper mold head 21, respectively.

[0033] When the wiping assembly 1 cleans the coating die head 2, the driving component 34 drives the connecting plate 35 to move forward, so that the connecting track 36 and the connecting boss 351 are connected to the guide rail 11 and the front end face of the upper die head 21 respectively. The elastic circular plate 17 can roll from the upper die head 21 onto the connecting boss 351, and the slider 12 can also slide onto the connecting track 36, so that the entire wiping assembly 1 is aligned with the front side of the driving component 34. The driving component 34 drives the wiping assembly 1 to move backward, so that the wiping assembly 1 enters the cleaning chamber 32. The liquid supply component 33 sprays out cleaning liquid to clean the wiping head 181 to remove the residual adhesive on the wiping head 181.

[0034] The cleaning components 3 are arranged in two sets and symmetrically on the left and right sides of the coating die head 2. If the cleaning components 3 are only arranged on one side of the coating die head 2, the wiping component 1 needs to make one round trip on the coating die head 2 to enter the cleaning components 3. However, if the cleaning components 3 are arranged on both sides of the coating die head 2, the wiping component 1 can be cleaned after each unidirectional movement, thus improving the cleaning efficiency.

[0035] The cleaning chamber 32 includes a chamber body 321, a chamber door 322, a rotating shaft 323, an elastic element 324, a drive plate 325, and a cylinder 326. The chamber body 321 is fixed on the mounting plate 31 and has an opening on the front side. The rotating shaft 323 is rotatably mounted on the lower side of the chamber body 321. The lower end of the chamber door 322 is fixed on the rotating shaft 323. The two sets of elastic ends of the elastic element 324 are fixedly connected to the chamber body 321 and the chamber door 322, respectively. One end of the drive plate 325 is fixed to the end of the rotating shaft 323. The cylinder 326 is fixed on the chamber body 321 and its telescopic end corresponds to the other end of the drive plate 325.

[0036] like Figure 4 As shown, the elastic element 324 can be a torsion spring, which is sleeved on the rotating shaft 323. When the cylinder 326 is retracted, the elastic end of the torsion spring drives the chamber door 322 to be in the open state, so that the wiping assembly 1 can enter the chamber 321. When the wiping assembly 1 enters the chamber 321, the cylinder 326 pushes out and pushes the drive plate 325. The drive plate 325 causes the rotating shaft 323 to rotate, which drives the chamber door 322 to close. Thus, when cleaning the wiping head 181, the cleaning fluid will not splash outward, improving the safety and cleanliness of the cleaning environment.

[0037] like Figure 5 As shown, the elastic element 324 can also be a tension spring. The two ends of the tension spring are fixed to the lower end of the chamber body 321 and the lower end of the chamber door 322, respectively. When the cylinder 326 is retracted, the tension spring closes the chamber door 322. When the cylinder 326 is pushed out and pushes the drive plate 325, the drive plate 325 causes the rotating shaft 323 to rotate, which drives the chamber door 322 to open. At this time, the tension spring is in a stretched state.

[0038] The bottom front side of the chamber 321 is provided with an inclined flow guide slope 3211, and the bottom of the chamber 321 is also provided with a liquid outlet hole 3212 corresponding to the rear side of the flow guide slope 3211.

[0039] The outlet 3212 is connected to the collection container through a pipe. The waste liquid after cleaning flows to the bottom of the chamber 321 through the guide slope 3211 and enters the collection container through the outlet 3212.

[0040] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
