[0033] In the embodiment of the present application, the feeding wheel 21 is used for feeding, and the paper guiding roller 22 conveys the label paper to the limit adjusting mechanism; the first width adjusting component of the first limiting table 31 and the second width adjusting component of the second limiting table 32 can perform limit adjustment according to the width of the label paper, so that the label paper can be stably and accurately conveyed to the peeling mechanism for peeling; the label and the release paper are peeled by the peeling blade 41, the peeled release paper is pulled by the material receiving mechanism for material receiving, and the peeled label is moved to the label receiving table 42 under the push of the release paper, and labeling operations are performed by a manipulator or the like; through the mutual abutment of the pressing roller 52 and the traction roller 51, the release paper passes through between the pressing roller 52 and the traction roller 51, and the driving component drives the traction wheel to rotate so as to drive the peeled release paper to move towards the material receiving wheel 53 side, and the material receiving wheel 53 performs material receiving on the release paper, completing the automatic peeling of the label. The present application can realize the automatic peeling of the label, and can be applicable to label papers of different width sizes, improving the efficiency and accuracy of label peeling.

[0034] Next, a forward-pushing type label peeling device in this exemplary embodiment will be further described.

[0035] In the embodiment of the present application, the feeding mechanism includes a feeding wheel 21 and a plurality of paper guide rollers 22. The feeding wheel 21 and the plurality of paper guide rollers 22 are arranged at intervals and offset in sequence along the feeding direction on one inner wall of the frame 1. The feeding wheel 21 is a self-driven rotating wheel. The label paper is wound around the feeding wheel 21, and the feeding wheel 21 rotates to feed the paper. The plurality of paper guide rollers 22 are passive roller shafts, and are driven by the rear-end collecting mechanism to assist the label paper to move backward for feeding. The limiting and adjusting mechanism includes a first limiting platform 31 and a second limiting platform 32. The first limiting platform 31 and the second limiting platform 32 are arranged adjacent to each other in sequence along the feeding direction on one side of the frame 1 and are located behind the paper guide rollers 22. The first limiting platform 31 and the second limiting platform 32 are used to support the label paper. The first limiting platform 31 is provided with a first width adjusting component for adjusting the conveying width of the first limiting platform 31, and the second limiting platform 32 is provided with a second width adjusting component for adjusting the conveying width of the second limiting platform 32.

[0036] As an example, the first width adjusting component includes two first adjusting plates 33. The two first adjusting plates 33 are oppositely arranged on the top of the first limiting platform 31. Among them, the length direction of the first adjusting plate 33 is consistent with the feeding direction. The first limiting platform 31 is provided with multiple rows of adjusting holes 311. The multiple rows of adjusting holes 311 are arranged at intervals along the feeding direction. Each row of the adjusting holes 311 is formed by arranging a plurality of round holes at intervals. The first adjusting plate 33 is respectively provided with waist-shaped holes 331 at positions corresponding to the multiple rows of adjusting holes 311. The waist-shaped holes 331 and the round holes are connected by a first locking member. The first locking member can be a pin shaft or a locking bolt. By arranging the two first adjusting plates 33 on the first limiting platform 31, a first limiting space for the label paper is formed. The distance between the two first adjusting plates 33 can be adjusted according to the width of the label paper. The specific adjusting method is as follows: When adjusting, remove the first locking member, move the two first adjusting plates 33 to the round holes at appropriate positions, and then tighten the first locking member to fix it. In this way, the label paper with a suitable width can be limited and guided to prevent it from shifting. By setting the waist-shaped holes 331, the accuracy of width adjustment can be improved.

[0037] As an example, the second width adjustment component includes two second adjustment plates 34. The two second adjustment plates 34 are oppositely arranged on the top of the second limiting platform 32. Among them, the length direction of the second adjustment plate 34 is consistent with the feeding direction; a chute 323 is formed on the top of the second limiting platform 32. The chutes 323 are arranged at intervals along the feeding direction and are perpendicular to the feeding direction; a slider 341 adapted to the chute 323 is provided at the bottom of the second adjustment plate 34. The slider 341 is tightly connected to the chute 323 through a second locking member. By providing two second adjustment plates 34 on the second limiting platform 32, a second limiting space for the label paper is formed. The distance between the two second adjustment plates 34 can be adjusted according to the width of the label paper. The specific adjustment method is as follows: when adjusting, remove the second locking member, move the second adjustment plates 34 along the chute 323 to appropriate positions respectively, and then tighten the second locking member to fix it. In this way, the label paper with the appropriate width can be limited and guided to prevent the label paper fed into the peeling blade 41 from shifting.

[0038] It should be noted that the structures and adjustment methods of the first width adjustment component and the second width adjustment component are different. The width adjustment of the first width adjustment component is carried out between the distances of multiple circular holes in each row of adjustment holes 311, and the adjustment accuracy is relatively low; while the width adjustment of the second width adjustment component is carried out within the length range of the chute 323, with a large adjustable range and high adjustment accuracy. The purpose is that the second limiting platform 32 is adjacent to the glass mechanism, and it is required that the label paper be fed into the peeling mechanism smoothly and accurately. The first limiting platform 31 is located between the feeding mechanism and the second limiting platform 32, and can roughly adjust the width of the label paper sent by the feeding mechanism, playing a transitional role to avoid phenomena such as bending and tearing of the label paper directly sent by the feeding mechanism after being precisely adjusted by the second width adjustment component. Through the above structure, the label paper can be stably fed into the peeling mechanism for label peeling.

[0039] As an example, on the top surface of one end of the first limiting platform 31 close to the second limiting platform 32, a plurality of first negative pressure suction holes 312 are formed. On the side wall or bottom of the first limiting platform 31, a first negative pressure pipe connection hole communicating with the first negative pressure suction holes 312 is formed. Negative pressure is introduced into the first limiting platform 31 through the first negative pressure pipe connection hole, and the label paper on its top surface is negatively pressure adsorbed through the plurality of first negative pressure suction holes 312, so that it fits with the first limiting platform 31 and is stably fed to the second limiting platform 32; in the middle part of the second limiting platform 32, a second negative pressure suction hole 324 is formed. On the side wall or bottom of the second limiting platform 32, a second negative pressure pipe connection hole communicating with the second negative pressure suction hole 324 is formed. Negative pressure is introduced into the second limiting platform 32 through the second negative pressure pipe connection hole, and the label paper on its top surface is negatively pressure adsorbed through the plurality of second negative pressure suction holes 324, so that it fits with the second limiting platform 32 and is stably fed to the glass mechanism for peeling. Through the above structure, during the process of feeding the label paper into the peeling mechanism, the label paper is prevented from arching or shifting due to environmental factors, so that the label paper can be smoothly fed into the peeling mechanism.

[0040] In an embodiment of the present application, the peeling mechanism includes a peeling blade 41 and a label receiving table 42. The peeling blade 41 is arranged at one end of the second limiting platform 32 away from the feeding wheel 21; the label receiving table 42 is arranged on the machine frame 1 and is adjacent to the peeling blade 41. A label sensor is arranged at one end of the label receiving table 42 close to the peeling blade 41. One end of the peeling blade 41 close to the label receiving table 42 is in the shape of an inclined blade for peeling the label from the release paper. The label receiving table 42 is used for receiving the peeled label. The top surface of the label receiving table 42 is coated with a non-stick coating or plated with a non-stick coating layer to prevent the peeled label from adhering to the label receiving table 42. The label sensor is an optical fiber sensor for detecting whether the label paper is peeled off.

[0041] As an example, a pressing plate 43 is arranged at the top of one end of the second limiting platform 32 close to the label receiving table 42, and the pressing plate 43 covers the top of the peeling blade 41. The pressing plate 43 is used for pressing the label paper to be peeled, applying a certain pressure, and can improve the peeling effect.

[0042] As an example, the peeling blade 41 is embedded in the end of the second limiting platform 32 and is flush with the platform surface of the second limiting platform 32, avoiding obstruction caused by unevenness, so that the label paper can be smoothly fed into the peeling mechanism for peeling.

[0043] In the embodiment of the present application, the material receiving mechanism includes a traction roller 51, a pressing roller 52 and a material receiving wheel 53. The traction roller 51 is arranged below the second limiting platform 32 and is driven to rotate by a driving assembly; the pressing roller 52 is rotatably connected to the bottom of the second limiting platform 32 and abuts against the traction roller 51; the material receiving wheel 53 is arranged on the frame 1 and is located below the feeding mechanism. The peeled release paper passes through between the pressing roller 52 and the traction roller 51. By the pressing roller 52 and the traction roller 51 abutting against each other, and the traction roller 51 is driven to rotate by the driving assembly, the frictional force for the forward movement of the release paper can be provided to push the release paper to move towards the material receiving wheel 53. The material receiving wheel 53 is a self-driven rotating wheel for winding and receiving the release paper.

[0044] As an example, the driving assembly includes a stepping motor 54, a driving gear 55 and a driven gear 56. The stepping motor 54 is arranged on the frame 1. The driving gear 55 is connected to the output shaft of the stepping motor 54. The driven gear 56 is sleeved on one end of the traction roller 51 and meshes with the driving gear 55. The stepping motor 54 drives the driving gear 55 to rotate. The driving gear 55 drives the driven gear 56 to rotate. The driven gear 56 drives the traction roller 51 to rotate, thereby pushing the release paper to move.

[0045] As an example, it further includes a controller 8 and a touch display screen 7. The controller 8 is arranged inside the frame 1. The touch display screen 7 is arranged on the top of the frame 1. The label sensor, the stepping motor 54 and the touch display screen 7 are respectively electrically connected to the controller 8. The operation of the whole device is controlled by the controller 8. The touch display screen 7 can observe the operation state in real time and control the device, improving the automation of the device.

[0046] As an example, the frame 1 includes a bottom plate 11, end plates 12, a first side plate 13 and a second side plate 14. The first side plate 13 and the second side plate 14 are oppositely arranged on both sides of the bottom plate 11. The end plate 12 is arranged at one end of the bottom plate 11 away from the feeding mechanism. The label receiving platform 42 is installed on the end plate 12; a dial groove 131 is formed in the top of the first side plate 13 corresponding to the label receiving platform 42. A dial piece 132 is hinged in the dial groove 131; a through hole is formed in the top of the first side plate 13 near the dial groove 131.

[0047] One side of the second limiting platform 32 is hinged to the second side plate 14. An insertion block 321 is elastically connected to the side of the second limiting platform 32 opposite to the second side plate 14. The insertion block 321 faces the through hole and is inserted into the through hole. A limiting convex block 322 is further provided on the side of the second limiting platform 32 opposite to the second side plate 14. The limiting convex block 322 faces the dial 132 and abuts against the top of the dial 132. By providing the dial 132, it is used to lift the second limiting platform 32 upward, so that the release paper can pass through between the traction roller 51 and the pressing roller 52 inside the frame 1. When not in use, it is placed in the dial groove 131, which will not occupy space and will not affect the use of the peeling mechanism.

[0048] Specifically, when it is necessary to lift the second limiting platform 32, press the insertion block 321 to retract it into the through hole, and then rotate the dial 132 to tilt the second limiting platform 32 upward to lift it. When resetting, directly rotate the second limiting platform 32 downward so that the insertion block 321 is inserted into the through hole to limit and fix it. The limiting convex block 322 is placed on the dial 132, and at this time, the dial 132 can limit it. Through the above structure, the label paper is convenient and fast to install and the operation is simple.
