[0011] It has at least the following beneficial effects:

[0012] The label material roll is sleeved on the unwinding roller. As the unwinding roller rotates, the label material roll is unwound from back to front. The label material roll unwound and moving from back to front passes through the peeling device. Under the action of the peeling device, the label sticker in the label material roll unwound is peeled off from the smooth paper. Then the handling device grabs the label sticker peeled off from the smooth paper and transports and pastes the label sticker onto the product to complete the labeling of the product.

[0040] The additional aspects and advantages of the present utility model will be partially given in the following description, partially become apparent from the following description, or be understood through the practice of the present utility model.

[0041] Reference Figure 1 and Figure 2 , the labeling device of the present utility model includes:

[0042] A frame 100;

[0043] An unwinding roller 400, the unwinding roller 400 is parallel to the left - right direction, the unwinding roller 400 is used for sleeving a label material roll, and the left end of the unwinding roller 400 is rotatably connected to the frame 100 so that the unwinding roller 400 can unwind the label material roll from the back to the front;

[0044] A peeling device 200, the peeling device 200 is arranged in front of the unwinding roller 400, and the peeling device 200 is used for peeling the label sticker from the smooth paper in the unwound label material roll;

[0045] A handling device 300, the handling device 300 is used for handling and pasting the label sticker peeled from the smooth paper onto the product;

[0046] A winding roller 500, the winding roller 500 is parallel to the left - right direction, the winding roller 500 is arranged behind the peeling device 200, and the left end of the winding roller 500 is rotatably connected to the frame 100 so that the winding roller 500 can wind the smooth paper from the front to the back;

[0047] The swing arm 160 and the first tension roller 110. One end of the swing arm 160 is rotatably connected to the frame 100. The first tension roller 110 is parallel to the left - right direction. The first tension roller 110 is arranged between the peeling device 200 and the unwind roller 400. The first tension roller 110 is used to press against the upper surface of the label material roll unwound between the peeling device 200 and the unwind roller 400. The first tension roller 110 is used to press against the upper surface of the unwound label material roll. The right end of the first tension roller 110 is rotatably connected to the other end of the swing arm 160, so that the first tension roller 110 can swing following the swing arm 160 to change the pressure between the first tension roller 110 and the unwound label material roll.

[0048] It can be understood that the label material roll is sleeved on the unwind roller 400. As the unwind roller 400 rotates, the label material roll is unwound from the back to the front. The label material roll unwound from the back to the front passes through the peeling device 200. Under the action of the peeling device 200, the label stickers in the unwound label material roll are peeled off from the smooth paper. Then the handling device 300 grabs the label stickers peeled off from the smooth paper and transports and pastes the label stickers onto the product to complete the labeling of the product. The take - up roller 500 is used to wind up the remaining smooth paper after the label stickers are peeled off, so that the remaining smooth paper can move from the front to the back and be wound up by the take - up roller 500. The first tension roller 110 is arranged between the peeling device 200 and the unwind roller 400. The first tension roller 110 presses against the upper surface of the label material roll unwound between the peeling device 200 and the unwind roller 400. One end of the swing arm 160 is rotatably connected to the frame 100. The right end of the first tension roller 110 is rotatably connected to the other end of the swing arm 160. By rotating the swing arm 160, the first tension roller 110 can be swung. When the first tension roller 110 swings downward, the pressure between the first tension roller 110 and the unwound label material roll can be increased, avoiding the slack of the unwound label material roll, so that the label stickers can be smoothly peeled off from the smooth paper, and then the handling device 300 can smoothly transport and paste the label stickers onto the product, avoiding the phenomenon of missed labeling of the product, which is beneficial to improving the yield rate of the product. On the other hand, when the first tension roller 110 swings upward, the pressure between the first tension roller 110 and the unwound label material roll can be reduced, avoiding the breakage of the unwound label material roll due to excessive tension, ensuring the smooth progress of the labeling process. The first tension roller 110 is swingably connected to the frame 100 through the swing arm 160, and the tension of the unwound label roll can be adjusted by swinging the first tension roller 110.

[0049] Reference Figures 2 to 4, the peeling device 200 includes a peeling blade block 210 and an anti - sticking platform 220. Both the peeling blade block 210 and the anti - sticking platform 220 are arranged on the frame 100. The peeling blade block 210 is arranged in front of the unwinding roller 400, and the anti - sticking platform 220 is arranged in front of the peeling blade block 210. The peeling blade block 210 is used for the label material unwound from the unwinding roller to be wound thereon, so that the front end of the peeling blade block 210 can scrape the lower surface of the label material roll unwound from the unwinding roller, and the label sticker in the label material roll at the front end of the peeling blade block 210 can be peeled off from the glossy paper. The gap between the front end of the peeling blade block 210 and the anti - sticking platform 220 is used for the glossy paper to pass through, so that the label sticker peeled off from the glossy paper can fall onto the anti - sticking platform 220. It can be understood that the texture of the glossy paper is relatively soft, and the texture of the label sticker is relatively hard. The label material unwound from the unwinding roller is wound on the peeling blade block 210, and the front end of the peeling blade block 210 presses against the lower surface of the label material roll unwound from the unwinding roller. The area between the peeling blade block 210 and the unwinding roller is the unwinding area, that is, the glossy paper and the label sticker in the unwinding area move from back to front. The area between the peeling blade block 210 and the rewinding is the rewinding area, that is, the glossy paper in the rewinding area moves from front to back. Since the front end of the peeling blade block 210 presses against the lower surface of the label material roll unwound from the unwinding roller, that is, against the lower surface of the glossy paper at the unwinding end, as the glossy paper moves, the front end of the peeling blade block 210 can scrape the lower surface of the glossy paper. Since the material of the label sticker is relatively hard, the label sticker will not move with the glossy paper under the peeling blade block 210, and the label sticker will gradually be peeled off from the glossy paper at the front end of the peeling blade block 210. The glossy paper passes through the gap between the front end of the peeling blade block 210 and the anti - sticking platform 220. As the label sticker continues to move forward, the label sticker will be completely peeled off from the glossy paper and fall onto the anti - sticking platform 220. Finally, the handling device 300 transports the label sticker on the anti - sticking platform 220 and pastes it onto the product.

[0050] The anti - sticking platform 220 is a platform used to prevent objects from adhering. The surface of the anti - sticking platform 220 is coated with a layer of anti - sticking coating, which can prevent the label sticker from sticking to the anti - sticking platform 220, enabling the handling device 300 to smoothly transport the label sticker.

[0051] Reference Figure 3, the stripping device 200 further includes two guiding blocks 211 which are respectively arranged at the left and right ends of the upper surface of the stripping blade block 210. The gap between the two guiding blocks 211 is used for the label material roll unwound from the unwind to pass through. It can be understood that the gap between the two guiding blocks 211 is used for the label material roll unwound from the unwind to pass through, and the two guiding blocks 211 can abut against the left and right sides of the label material roll unwound from the unwind, so that the two guiding blocks 211 can guide and position the label material roll unwound from the unwind in the left and right directions, avoiding the shaking of the label material roll unwound from the unwind in the left and right directions, which is beneficial to improving the stability of the label material roll during movement, and further beneficial to improving the labeling accuracy of the handling device 300.

[0052] Reference Figure 3 , the stripping device 200 further includes two first fasteners. The two guiding blocks 211 are both slidably connected to the stripping blade block 210 in the left and right directions to change the distance between the two guiding blocks 211, and the two guiding blocks 211 are respectively fixed to the stripping blade block 210 through the two first fasteners. The two guiding blocks 211 are both slidably connected to the stripping blade block 210 in the left and right directions. By sliding the two guiding blocks 211, the distance between the two guiding blocks 211 can be changed to adapt to label material rolls of different specifications, thereby improving the applicability of the stripping blade block 210. The two first fasteners are both first bolts. Waist holes parallel to the left and right directions are opened on the two guiding blocks 211, and first threaded holes are opened on the left and right sides of the upper surface of the stripping blade block 210. The two first bolts respectively pass through the waist holes on the two guiding blocks 211, and the two first bolts are respectively threadedly connected to the inner walls of the two first threaded holes. The nuts of the two first bolts respectively press against the two guiding blocks 211, so that the guiding blocks 211 can be fixed to the stripping blade block 210 after movement.

[0053] Reference Figure 3 , a length scale 213 is further arranged on the upper surface of the stripping blade block 210. The length scale 213 is parallel to the left and right directions, and the two guiding blocks 211 cooperate with the length scale 213 to obtain the distance value between the two guiding blocks 211. It can be understood that the length scale 213 can directly indicate the distance value between the two guiding blocks 211, so that the operator can adjust the distance between the two guiding blocks 211 according to the specification of the label roll material.

[0054] Reference Figure 3, the two guide blocks 211 are each provided with a limit plate 212, and the gap between the two limit plates 212 and the upper surface of the stripping block 210 is used for the unrolled label roll to pass through. It can be understood that the gap between the two limit plates 212 and the upper surface of the stripping block 210 is used for the unrolled label roll to pass through, and the two limit plates 212 can abut against the upper surface of the unrolled label roll, so that the two limit plates 212 can limit the unrolled label roll in the up and down directions, avoiding the unrolled label roll from shaking in the up and down directions, which is beneficial to improving the stability of the label roll during the movement process, and further beneficial to improving the accuracy of labeling of the transport device 300.

[0055] refer to Figure 2 and Figure 5 The labeling device further includes a second tensioning roller 120. The frame 100 is provided with two guide grooves 121 extending in the front-to-back direction. The second tensioning roller 120 is parallel to the left-to-right direction. The second tensioning roller 120 is arranged between the stripping device 200 and the winding roller 500. The left and right ends of the second tensioning roller 120 are respectively inserted into the two guide grooves 121 so that the second tensioning roller 120 can slide in the front-to-back direction. The second tensioning roller 120 is connected to the swing arm 160 by transmission so that the swing arm 160 swinging downward can drive the second tensioning roller 120 to move forward and increase the pressure between the second tensioning roller 120 and the glossy paper. Specifically, the second tensioning roller 120 is arranged below the stripping knife block 210, and the second tensioning roller 120 presses against the upper surface of the glossy paper between the stripping device 200 and the winding roller 500. The first tensioning roller 110 is used to perform tensioning and adjustment on the label stickers and glossy paper in the unwinding area, and the second tensioning roller 120 can perform tensioning and adjustment on the glossy paper in the winding area.

[0056] In the process of adjusting the tension of the glossy paper, the operator can swing the swing arm 160 downward, so that the pressure between the first tensioning roller 110 and the glossy paper in the unwinding area increases, thereby increasing the tension of the glossy paper in the unwinding area. Since the second tensioning roller 120 is connected to the swing arm 160 by transmission, when the swing arm 160 swings downward, the second tensioning roller 120 moves forward. The second tensioning roller 120 moving forward can increase the pressure between the second tensioning roller 120 and the glossy paper, thereby increasing the tension of the glossy paper in the winding area, which not only allows the label sticker to be peeled off smoothly, but also ensures that the winding roller 500 can smoothly wind up the glossy paper. It is not difficult to see that when the first tensioning roller 110 adjusts the tension of the glossy paper in the winding area, the second tensioning roller 120 can synchronously adjust the tension of the glossy paper in the unwinding area, and the synchronous adjustment can improve the adjustment efficiency of the tension of the glossy paper.

[0057] refer to Figure 5, the labeling device further includes a movable pin 181, a mounting block 180, a rotating shaft 170, and an elastic member 182. The rotating shaft 170 is parallel to the left-right direction, and both the left and right ends of the rotating shaft 170 are rotatably connected to the frame 100. One end of the swing arm 160 is connected to the right end of the rotating shaft 170. A dial block 171 is provided on the side of the rotating shaft 170 facing the second tension roller 120. The mounting block 180 is provided on the frame 100 and is disposed between the rotating shaft 170 and the second tension roller 120. A guiding hole 183 parallel to the front-rear direction is formed in the mounting block 180. The movable pin 181 is inserted into the guiding hole 183. The elastic member 182 is sleeved on the movable pin 181, and the front and rear ends of the elastic member 182 are respectively connected to the mounting block 180 and the movable pin 181. The rear end of the movable pin 181 abuts against the dial block 171, and the front end of the movable pin 181 can abut against the second tension roller 120.

[0058] It can be understood that when the operator swings the swing arm 160 downward, the rotating shaft 170 rotates and drives the dial block 171 to swing downward. The downward-swinging dial block 171 can drive the movable pin 181 to move forward, and the elastic member 182 is compressed. Further, the movable pin 181 can drive the second tension roller 120 to move forward. The forward-moving second tension roller 120 can increase the pressure between the second tension roller 120 and the smooth paper, thereby increasing the tension of the smooth paper in the winding area. When it is necessary to replace the label roll, the operator can swing the swing arm 160 upward so that the first tension roller 110 is disengaged from the abutment with the smooth paper in the unwinding area. The dial block 171 swings upward following the swing arm 160. Under the action of the elastic member 182, the rear end of the movable pin 181 always abuts against the dial block 171. After the dial block 171 swings upward, the elastic member 182 extends, and the elastic member 182 drives the movable pin 181 to move backward, so that the front end of the movable pin 181 is disengaged from the abutment with the second tension roller 120. At this time, the second tension roller 120 loses the supporting force of the movable pin 181, so that the pressure between the second tension roller 120 and the smooth paper rapidly decreases, and further the smooth paper is completely in a relaxed state, facilitating the operator to replace the label roll. It is not difficult to see that when the first tension roller 110 moves away from the smooth paper in the winding area, the pressure between the second tension roller 120 and the smooth paper in the unwinding area can be synchronously and rapidly reduced, so that the smooth paper can quickly be in a completely relaxed state, facilitating the operator to replace the label roll and improving the convenience for the operator to replace the label roll.

[0059] Reference Figure 5, a roller 172 is rotatably connected to one side of the shifting block 171 facing the second tensioning roller 120, and the roller 172 abuts against the rear end of the movable pin 181. It can be understood that the shifting block 171 abuts against the rear end of the movable pin 181 through the roller 172, and the roller can rotate during the process of driving the movable pin 181 to move, so as to reduce the friction between the shifting block 171 and the movable pin 181, which is beneficial to reducing the wear of the movable pin 181.

[0060] Reference Figure 5 , the labeling device further includes a second fastener. A guiding arc-shaped hole 162 is formed on the frame 100, a mounting hole is formed on the swing arm 160, and a second threaded hole is formed on the shifting block 171.

[0061] Reference Figure 6 , the handling device 300 includes an XZ-axis driving mechanism 310, a rotation driving mechanism 320 and a suction cup mechanism 330. The suction cup mechanism 330 is used for adsorbing or releasing label stickers. The XZ-axis driving mechanism 310 is used for driving the suction cup mechanism 330 to move in the front-back direction and the up-down direction, so that the label stickers adsorbed by the suction cup mechanism 330 can be pasted onto the product. The rotation driving mechanism 320 is used for driving the suction cup mechanism 330 to rotate, so that the label stickers adsorbed by the suction cup mechanism 330 can rotate. It can be understood that the XZ-axis driving mechanism 310 drives the suction cup mechanism 330 to move in the front-back direction and the up-down direction, so that the suction cup mechanism 330 moves to the anti-sticking platform 220 and adsorbs the anti-sticking paper on the anti-sticking platform 220. Then, the XZ-axis driving mechanism 310 continues to drive the suction cup mechanism 330 to move, so that the label stickers are pasted on the product. During the process of the suction cup mechanism 330 moving towards the product, the rotation driving mechanism 320 drives the suction cup mechanism 330 to rotate, so that the label stickers rotate, thereby adjusting the posture of the label stickers to ensure that the label stickers pasted on the product can conform to the specified posture. Specifically, the output end of the XZ-axis driving mechanism 310 is connected to the rotation driving mechanism 320, and the output end of the rotation driving mechanism 320 is connected to the suction cup mechanism 330.
