[0025] Coating mechanism 6: It includes an electric push rod 61, a lifting frame 62, a connecting seat 63, a coating roller 64 and a cleaning roller assembly 66. The electric push rod 61 is arranged on the upper side of the coating shell 1, and the input end of the electric push rod 61 is electrically connected to the output end of the single-chip microcomputer 2. The telescopic end of the electric push rod 61 is provided with a lifting frame 62, and the lower left end of the lifting frame 62 is provided with a connecting seat 63. The interior of the connecting seat 63 is connected to the coating roller 64 by rotating through a rotating shaft. A cleaning roller assembly 66 is provided between the front and rear sides of the connecting seat 63. The cleaning roller assembly 66 is installed in conjunction with the coating roller 64. The coating mechanism 6 also includes a glue delivery assembly 65, a scraping seat 67 and a storage shell 68. The glue delivery assembly 65 is provided between the coating shell 1 and the connecting seat 63, and the lower right end of the lifting frame 62 is provided with a scraping seat 6 7.

The glue storage shell 651 is arranged on the upper side of the coating shell 1, and the top wall of the connecting seat 63 is penetrated by a hard tube 653. The lower end of the hard tube 653 is provided with a glue discharge pipe 654. The upper end of the hard tube 653 is connected to the bottom of the glue storage shell 651 through the hose 652. The cleaning roller assembly 66 includes a scraping shell 661, a discharge trough 662 and a storage shell 1 663. The scraping shell 661 is arranged between the front and rear sides of the connecting seat 63, and the scraping shell 661 is installed in conjunction with the glue coating roller 64. The front and rear sides of the scraping shell 661 are provided with a discharge trough 662. The front and rear sides of 61 are both equipped with a storage shell 1 663. The coating mechanism 6 also includes a rangefinder 69. The rangefinder 69 is arranged in the middle of the lower side of the lifting frame 62. The rangefinder 69 is bidirectionally electrically connected to the single-chip computer 2. The colloid in the glue storage shell 651 flows along the hose 652 and the hard tube 653 through the circular hole on the glue outlet pipe 654 to the outer side of the glue coating roller 64. As the contact friction between the glue coating roller 64 and the tape base layer causes the glue coating roller 64 to rotate and thereby perform a colloid coating operation on the tape base layer. As the tape base material continues to move to the right, the colloid on the surface of the tape base layer is scraped flat by the scraping seat 67. The excess colloid falls along the scraping seat 67 into the storage shell 2 68. During the glue coating operation of the tape base material, the glue coating roller 64 After the substrate is coated, its outer arc surface contacts the scraper shell 661 during rotation. The upper arc surface of the scraper shell 661 scrapes and collects the excess glue on the outside of the glue roller 64 to prevent the glue on the outer side of the glue roller 64 from being excessively solidified, thereby avoiding interference with the glue coating operation of the tape base layer. The excess glue on the glue roller 64 collected by the scraper shell 661 is moved to the storage shell 1 663 through the discharge chute 662. When the thickness of the tape substrate changes, the single-chip microcomputer 2 starts the rangefinder 69. The rangefinder 69 emits a light signal to illuminate the upper surface of the substrate and reflects it back to the initial position. The distance between the tape substrate and the lifting frame 62 is measured according to the propagation speed and time of the light signal, and the measurement result is transmitted to the single-chip microcomputer 2 in the form of an electrical signal.The single-chip computer 2, in conjunction with the vertical distance between the distance meter 69 and the lower outer end of the glue roller 64, activates the electric push rod 61, causing the telescopic end of the electric push rod 61 to indirectly drive the glue roller 64 upward to a specified position, thereby enabling the device to apply glue to tape substrates of different thicknesses. The device can automatically scrape and collect excess glue on the surface of the glue roller 64 to prevent glue solidification, thereby improving the glue application effect of the tape substrate. At the same time, the device can automatically adjust the glue application position according to the thickness of the tape substrate, making the device applicable to a wide range of tape coating operations.

[0026] The working principle of the automatic coating device for adhesive tape production provided by the present invention is as follows: when the adhesive tape is coated on the surface during the production process, the adhesive tape is first passed through the device from left to right, and the adhesive tape substrate is coated with auxiliary rollers 4 for auxiliary support. The lower end of the outer side of the adhesive coating roller 64 contacts the upper surface of the adhesive tape substrate, and then the adhesive tape substrate is driven by an external power element for coating and transportation. The adhesive in the adhesive storage shell 651 flows along the hose 652 and the hard tube 653 through the circular hole on the adhesive outlet pipe 654 to the outer side surface of the adhesive coating roller 64. As the contact friction between the glue coating roller 64 and the tape base layer causes the glue coating roller 64 to rotate and thus perform a colloid coating operation on the tape base layer. As the tape base material continues to move right, the colloid on the surface of the tape base layer is scraped flat by the scraping seat 67, and the excess colloid falls into the storage shell 2 68 along the scraping seat 67. During the glue coating operation of the tape base material, after the glue coating roller 64 coats the tape base material, its outer arc surface contacts the scraping shell 661 during the rotation process. The upper arc of the scraping shell 661 faces the outer side of the glue coating roller 64. The excess colloid is scraped and collected to avoid excessive colloid on the outer side of the glue roller 64 and thus solidification, thereby avoiding interference with the tape base layer colloid coating operation. The excess colloid on the glue roller 64 collected by the scraper shell 661 is moved to the storage shell 1 663 through the discharge chute 662. The single-chip microcomputer 2 starts the ceramic heating plate 7 to heat the inside of the device to avoid the glue solidification. When the thickness of the tape substrate changes, the single-chip microcomputer 2 starts the rangefinder 69, and the rangefinder 69 emits a light signal to illuminate the upper surface of the substrate and reflects Returning to the initial position, the distance between the tape substrate and the lifting frame 62 is measured according to the propagation speed and time of the light signal, and the measurement result is transmitted to the single-chip microcomputer 2 in the form of an electrical signal. The single-chip microcomputer 2 combines the vertical distance between the distance meter 69 and the lower end of the outer side of the glue coating roller 64 to start the electric push rod 61, so that the telescopic end of the electric push rod 61 indirectly drives the glue coating roller 64 to move up to the specified position, so that the device can perform glue coating operations on tape substrates of different thicknesses, and the glue collected in the device is processed by closing the door 5.

[0027] It is worth noting that the single chip microcomputer 2 disclosed in the above embodiment can adopt MCS-51, the electric push rod 61 can adopt DTZ630, the rangefinder 69 can adopt ZM31-YHJ200, and the ceramic heating plate 7 can adopt MCH ceramic heating plate. The single chip microcomputer 2 controls the operation of the electric push rod 61, the rangefinder 69 and the ceramic heating plate 7 using methods commonly used in the prior art.
