Description

Technical Field

[0001] This utility model belongs to the field of double-sided tape coating technology, specifically relating to a device for precisely adjusting the coating thickness of double-sided tape. Background Technology

[0002] Double-sided tape coating refers to the process of uniformly coating adhesive onto both sides of a substrate (such as film or paper) using a coating machine to form an adhesive tape product with double-sided bonding function. The coating machine is the core equipment, typically including modules for unwinding, coating, drying, and rewinding. By precisely controlling parameters such as coating speed, thickness, and temperature, the uniformity of the adhesive layer and its bonding performance are ensured. Coating methods can be divided into blade coating, roller coating, or comma blade coating, suitable for adhesives of different viscosities.

[0003] In the double-sided tape coating process, the contact pressure control between the metering roller and the doctor blade of the coating machine is crucial. If the pressure cannot be adjusted accurately, the following problems may occur: when the pressure is too high, the doctor blade will squeeze the metering roller excessively, causing scratches on the roller surface; when the pressure is too low, the doctor blade cannot completely remove the excess coating liquid. Both of these will directly affect the uniformity of the coating thickness of the double-sided tape, resulting in unstable product quality. Utility Model Content

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Example

[0027] Reference Figure 1-4 This embodiment of the present invention provides a device for precisely adjusting the coating thickness of double-sided adhesive tape, comprising:

[0028] The coating mechanism 100 includes a coating roller 110, a liquid storage box 120 disposed below the coating roller 110 for storing coating liquid, a back roller 130 disposed on the top of the coating roller 110 for conveying double-sided tape, a metering roller 140 disposed on the surface of the coating roller 110, and a scraper 150 disposed on the surface of the metering roller 140 for scraping off the coating liquid.

[0029] The adjustment mechanism 200 includes an adjustment component 210 for adjusting the gap distance between the metering roller 140 and the coating roller 110, and a control component 220 for improving the adjustment accuracy of the metering roller 140.

[0030] The adjustment component 210 and the control component 220 are used to precisely adjust the pressure between the doctor blade 150 and the metering roller 140, so as to avoid the doctor blade 150 from scratching the metering roller 140 or the poor scraping effect. This solves the problem that the pressure between the doctor blade 150 and the metering roller 140 cannot be controlled in the traditional way, which causes the doctor blade 150 to scratch the metering roller 140 or the poor scraping effect, thus affecting the coating accuracy. This improves the accuracy of the coating thickness of the double-sided tape.

[0031] Specifically, the adjustment component 210 includes a fixed plate 211 fixedly mounted on the coating machine frame, two side plates 212 fixedly mounted on the ends of the fixed plate 211, a movable frame 213 slidably mounted between the two side plates 212 for mounting the metering roller 140, a servo motor 214 fixedly mounted on the surface of the fixed plate 211, and a lead screw 215 fixedly mounted on the output end of the servo motor 214 for driving the adjustment of the metering roller 140.

[0032] The servo motor 214 drives the lead screw 215 to rotate, the lead screw 215 drives the movable frame 213 to move, and the movable frame 213 drives the metering roller 140 to move, thereby adjusting the gap between the metering roller 140 and the coating roller 110 to adjust the coating thickness.

[0033] Furthermore, mounting bearings 216 are fixedly installed at both ends of the movable frame 213, and a rotating shaft is fixedly installed inside the metering roller 140, with the mounting bearings 216 sleeved on the surface of the rotating shaft.

[0034] Preferably, a slide groove 217 is provided on the side of the side plate 212 near the movable frame 213, and a slider 218 that is used in conjunction with the slide groove 217 is fixedly installed on the surface of the movable frame 213. The slider 218 is slidably installed inside the slide groove 217.

[0035] The sliding groove 217 and the slider 218 work together to limit the movement of the movable frame 213, improve the stability of the metering roller 140 during the adjustment process, and prevent it from shifting, which would affect the accuracy of the coating thickness.

[0036] Furthermore, the control component 220 includes an electric actuator 221, a connecting frame 222 fixedly mounted on the output end of the electric actuator 221, a strip plate 223 fixedly mounted on the end of the connecting frame 222, a plurality of springs 224 fixedly mounted on the surface of the strip plate 223, two rings 225 fixedly mounted on the end of the metering roller 140, and two pressure sensors 226 fixedly mounted on the end of the scraper 150 and used in conjunction with the rings 225;

[0037] The other end of the spring 224 is fixedly connected to the scraper 150, and the detection end of the pressure sensor 226 is in contact with the outer surface of the ring 225. The diameter of the ring 225 is matched with the diameter of the metering roller 140.

[0038] The output of pressure sensor 226 is electrically connected to the control board of the coating machine. The control board controls the use of electric push rod 221. Through the cooperation between pressure sensor 226 and ring 225, it monitors the contact pressure between doctor blade 150 and metering roller 140. When the pressure between doctor blade 150 and metering roller 140 decreases, it affects the doctor blade 150's scraping effect on the coating liquid. When the pressure is too high, it can cause the doctor blade 150 to scratch the surface of metering roller 140, affecting the accuracy of coating thickness. 226 transmits the monitored data to the control board of the coating machine. Under the analysis and processing of the control board, the electric push rod 221 is activated, causing the electric push rod 221 to move the connecting frame 222 and the strip plate 223. The pressure of the spring 224 on the scraper 150 is controlled, thereby controlling the pressure of the scraper 150 on the metering roller 140. This keeps the pressure of the scraper 150 on the metering roller 140 within a preset range, improving the scraping effect on the convex liquid on the surface of the metering roller 140 and avoiding scratches on the surface of the metering roller 140.

[0039] Specifically, a positioning rod 227 is fixedly installed at the bottom of the side plate 212, and a positioning hole for use with the positioning rod 227 is opened on the surface of the connecting frame 222. The end of the positioning rod 227 passes through the positioning hole.

[0040] The positioning bend 227 and the positioning hole are used to improve the stability of the connecting frame 222 when it moves, thereby improving the stability of the scraper 150 and preventing the scraper 150 from deviating and causing poor scraping effect on the surface of the metering roller 140.

[0041] Furthermore, a connecting plate is fixedly installed between the two positioning bent rods 227, and the electric push rod 221 is fixedly installed on the connecting plate.

[0042] The connecting plate is used to provide a mounting platform for the electric actuator 221, thereby improving the stability of the electric actuator 221 in use.

[0043] In use, the servo motor 214 drives the lead screw 215 to rotate, the lead screw 215 drives the movable frame 213 to move, and the movable frame 213 drives the metering roller 140 to move, thereby adjusting the gap between the metering roller 140 and the coating roller 110 to adjust the coating thickness.

[0044] The output of pressure sensor 226 is electrically connected to the control board of the coating machine. The control board controls the use of electric push rod 221. Through the cooperation between pressure sensor 226 and ring 225, it is used to monitor the contact pressure between doctor blade 150 and metering roller 140. Pressure sensor 226 transmits the monitored data to the control board of the coating machine. Under the analysis and processing of the control board, the start of electric push rod 221 is controlled, so that electric push rod 221 drives connecting frame 222 and strip plate 223 to move, controls the pressure of spring 224 on doctor blade 150, thereby controlling the pressure of doctor blade 150 on metering roller 140, so that the pressure of doctor blade 150 on metering roller 140 is kept within the preset range.

[0045] In summary, by adjusting the cooperation between component 210 and control component 220, the pressure between the doctor blade 150 and the metering roller 140 is precisely adjusted, avoiding scratches or poor removal effects caused by the doctor blade 150 on the metering roller 140. This solves the problem of uncontrollable pressure between the doctor blade 150 and the metering roller 140, which causes scratches or poor removal effects and affects coating accuracy, thus improving the accuracy of double-sided tape coating thickness.
