[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figure 1-5 This utility model provides a technical solution: a glue removal device for label printing, including a base 100, a support frame 101 and two mounting frames 102 mounted on the top of the base 100, two control motors 200 symmetrically mounted on one side of the support frame 101, mounting rollers 201 mounted on the output ends of the two control motors 200, and take-up rollers 202 detachably sleeved on the two mounting rollers 201. Label substrates 203 are mounted on the two take-up rollers 202, and two guide rollers 213 are rotatably mounted between the two mounting frames 102. The label substrates 203 are in contact with the two guide rollers 213. A glue remover tank 204 and a support plate 300 are mounted on the base 100. The upper part is connected to a spraying structure, which is used to spray water or adhesive remover onto the surface of the label substrate 203. The support plate 300 is connected to a wiping structure, which is used to wipe off the adhesive residue on the label substrate 203. The mounting frame 102 is connected to a drying structure, which is used to dry the residual water or adhesive remover. Turning on the two control motors 200 can control the corresponding mounting rollers 201 to rotate. The two mounting rollers 201 drive the two take-up rollers 202 to rotate in the corresponding direction. That is, if one take-up roller 202 rotates in the forward direction, the other rotates in the reverse direction, so as to control the upper take-up roller 202 to release the wound label substrate 203, and the lower take-up roller 202 to wind the label substrate 203.

[0027] Furthermore, the spraying structure includes a suction pump 205, which is installed above the adhesive remover tank 204. The suction end of the suction pump 205 is located inside the adhesive remover tank 204. The delivery end of the suction pump 205 is equipped with a delivery pipe 206. One end of the delivery pipe 206 is equipped with a telescopic pipe 207. A movable pipe 208 is installed on the telescopic pipe 207. Several nozzles 209 are evenly installed on the movable pipe 208. The nozzles 209 are located above the label substrate 203. A connecting cover 210 is installed on two mounting brackets 102. One end of the movable pipe 208 is slidably installed inside the connecting cover 210. The suction pump 205 can draw liquid from the adhesive remover tank 204. The adhesive remover tank 204 can store adhesive remover or water. The adhesive remover is delivered through the delivery pipe 206 to the telescopic pipe 207, then to the movable pipe 208, and finally sprayed onto the surface of the label substrate 203 through the nozzles 209 to soften the adhesive residue.

[0028] Furthermore, a reciprocating electric push rod 211 is installed above the connecting cover 210. A connecting plate 212 is installed at the telescopic end of the reciprocating electric push rod 211. The connecting plate 212 is installed at one end of the movable tube 208. By turning on the reciprocating electric push rod 211, the connecting plate 212 can be controlled to move horizontally back and forth, so that the connecting plate 212 drives the movable tube 208 to move back and forth. During the process, the telescopic tube 207 will extend and retract to adapt. The moving movable tube 208 can drive the nozzle 209 to swing, so that it can spray the label substrate 203 more evenly.

[0029] Furthermore, the wiping structure includes two limiting rollers 301, both of which are rotatably mounted on one side of a support plate 300. A reduction motor 302 is mounted on one side of the support plate 300, and the output end of the reduction motor 302 is mounted on the corresponding limiting roller 301. A sliding hole 303 is provided inside the support plate 300, and a slider 304 is slidably mounted in the sliding hole 303. A second limiting roller 305 is rotatably mounted on one side of the slider 304. The second limiting roller 305 and the two limiting rollers 301 are connected by the same cotton belt. 306. During the movement, the label substrate 203 will come into frictional contact with the cotton belt 306, wiping away the softened adhesive residue. Turning on the reduction motor 302 can drive the corresponding limit roller 1 301 to rotate slowly. Through the transmission cooperation between the limit roller 1 301, the limit roller 2 305 and the cotton belt 306, the cotton belt 306 can be driven to move in a circular motion, so that the cotton belt 306 can move the contaminated surface away from the label substrate 203 and make the clean surface contact the label substrate 203, changing the contact position between the cotton belt 306 and the label substrate 203, and improving the cleaning effect.

[0030] Furthermore, a spring 307 is installed on one side of the slider 304, and one end of the spring 307 is installed on the inner wall of the sliding hole 303. A guide rod 308 is installed inside the sliding hole 303. The slider 304 and the spring 307 are slidably sleeved on the guide rod 308. Pulling the slider 304 can cause it to move the second limiting roller 305 and loosen the cotton strip 306, so that the cotton strip 306 can be taken out. Then, a new cotton strip 306 is sleeved on the two limiting rollers 1 301 and the second limiting roller 2 305. Then, the slider 304 is released. At this time, the compressed spring 307 will push the second limiting roller 2 305 to support the cotton strip 306 again.

[0031] Example 2: Figure 2-4In order to remove residual liquid on the label substrate 203, a drying structure is arranged. The drying structure includes a flow guide hood 400, which is installed between two mounting brackets 102. A fan 401 is installed on one side of the corresponding mounting bracket 102. The blowing end of the fan 401 is connected to the flow guide hood 400. The opening of the flow guide hood 400 faces the label substrate 203. A heating tube 402 is installed on the inner wall of the mounting bracket 102. The heating tube 402 corresponds to the blowing end of the fan 401. After wiping, the label substrate 203 will pass through the flow guide hood 400. At this time, the fan 401 is turned on to blow air towards the flow guide hood 400. Under the guidance of the flow guide hood 400, the airflow can act on the surface of the label substrate 203. Turning on the heating tube 402 can heat and dry the airflow. The remaining features are the same as in Example 1.

[0032] The working principle is as follows: One end of the label substrate 203 wound on the upper take-up roller 202 is routed around two guide rollers 213 and connected to the lower take-up roller 202. Turning on the two control motors 200 controls the corresponding mounting rollers 201 to rotate. The two mounting rollers 201 then drive the two take-up rollers 202 to rotate in the corresponding directions; that is, if one take-up roller 202 rotates in the forward direction, the other rotates in the reverse direction. This controls the upper take-up roller 202 to release the wound label substrate 203, while the lower take-up roller 202 performs a rolling motion on the label substrate 203. During the winding process, the label substrate 203 passes through the connecting cover 210. Activating the suction pump 205 allows it to draw liquid from the descaling agent tank 204, which can store descaling agent or water. The descaling agent is then transported through the delivery pipe 206 to the telescopic pipe 207, and then to the movable pipe 208. Finally, it is sprayed onto the surface of the label substrate 203 through the nozzle 209 to soften the adhesive residue. Furthermore, activating the reciprocating electric push rod 211 controls the horizontal reciprocating movement of the connecting plate 212, causing the connecting plate 212 to drive the movable pipe 208... During the retraction process, the telescopic tube 207 will extend and retract to adapt. The moving movable tube 208 can drive the nozzle 209 to swing, allowing it to spray the label substrate 203 more evenly. Subsequently, the label substrate 203 will come into frictional contact with the cotton belt 306 during the movement, wiping away the softened adhesive residue and absorbing excess adhesive remover or water. During the process, the reduction motor 302 can drive the corresponding limit roller 301 to rotate slowly. Through the transmission cooperation of the limit roller 301, the limit roller 305, and the cotton belt 306, the label substrate 203 will be sprayed more evenly. The cotton belt 306 can move in a circular motion, causing the cotton belt 306 to move the contaminated surface away from the label substrate 203 and bring the clean surface into contact with the label substrate 203. By changing the contact position between the cotton belt 306 and the label substrate 203, the label substrate 203, after being wiped, will pass through the guide hood 400. At this time, the fan 401 can be turned on to blow air towards the guide hood 400. Under the guidance of the guide hood 400, the airflow can act on the surface of the label substrate 203. Turning on the heating tube 402 can heat the airflow and achieve the drying effect of the label substrate 203.

[0033] When the cotton belt 306 needs to be replaced, the slider 304 can be pulled to slide within the sliding hole 303. When the slider 304 slides, it will slide on the guide rod 308 and compress the spring 307. The sliding slider 304 will drive the second limiting roller 305 to move and loosen the cotton belt 306, so that the cotton belt 306 can be taken out. Then, the new cotton belt 306 is put on the two limiting rollers 1 301 and the second limiting roller 2 305. Then, the slider 304 is released. At this time, the compressed spring 307 will push the slider 304 to move back to its original position, which will then drive the second limiting roller 2 305 to support the cotton belt 306 again for convenient subsequent use.

[0034] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
