Description

Technical Field

[0001] This utility model relates to the technical field of label paper peeling, and in particular to an automatic label paper peeling structure. Background Technology

[0002] Label printing is widely used not only in stores, supermarkets, and shopping malls, but also in express delivery label printing. Traditional label printing requires manually peeling off the label paper and then pasting it onto the object, which is inconvenient. Summary of the Invention

[0003] The purpose of this utility model is to provide an automatic label peeling structure, and the technical problem to be solved is to provide a peeling structure that can automatically peel off the label.

[0004] To achieve the above objectives, the solution of this utility model is: an automatic label peeling structure for peeling off label paper. The label roll includes a base paper and label paper, and several label papers are sequentially pasted on the outer side of the base paper along the winding direction of the base paper. The structure includes a conveying channel, a peeling component, and a conveying roller component. The conveyor channel is used to convey label rolls and has a conveyor outlet for feeding the label rolls out. The peeling component is located at the conveyor outlet. After the label roll is conveyed to the peeling component, it can bend at an angle. The degree of bending of the label roll can make the label peel off from the backing paper. The conveyor roller assembly is spaced apart from the peeling assembly and includes an active roller and a driven roller. The peeled backing paper is clamped between the active roller and the driven roller. The active roller rotates actively to feed the backing paper out in the direction of rotation and pulls the label roll towards the conveying outlet.

[0005] Furthermore, the driving roller and the driven roller can be elastically clamped together.

[0006] Furthermore, it also includes a flap, with a pivot point in the middle of the flap, allowing its two ends to move in opposite directions. The two ends of the flap are a first end and a second end, respectively. The first end is used to install the driven roller, and the second end forms a pressing part. The flap is connected to an elastic element, which is used to elastically drive the first end closer to the driving roller, so that the driven roller is pressed tightly against the driving roller. The pressing part is used for hand pressing to overcome the elastic force of the elastic element and move the driven roller away from the driving roller.

[0007] Furthermore, the flip plate also has a bottom paper discharge port for feeding the bottom paper, and a serrated structure is formed on the inner wall of the bottom paper discharge port for tearing off the bottom paper.

[0008] Furthermore, the peeling assembly includes a peeling blade that extends upward at an angle away from the conveying channel. The peeling blade has a pointed tip at its end. The conveying roller assembly is located below the peeling blade. The label roll is wound around the blade with the backing paper against it and then turns downward at an angle before being conveyed to the conveying roller assembly.

[0009] Furthermore, the peeling assembly also includes a pressing element located between the conveying outlet and the peeling blade, which is used to press down the label roll so that the label roll is pressed down and then rolled up to wrap around the peeling blade.

[0010] Furthermore, a pressure strip is installed above the conveyor outlet. The pressure strip extends upward at an angle, forming a pressure surface on its bottom side, which is used to press the label paper together.

[0011] Furthermore, a guide roller is provided on the bottom side of the conveying channel, and the top side of the guide roller extends upward into the conveying channel for mounting the label roll.

[0012] Furthermore, the guide rollers can rotate actively to push the label rolls towards the delivery exit.

[0013] Furthermore, the conveying channel is a long and narrow channel, used only for conveying label rolls. The conveying channel has a conveying inlet for feeding label rolls. From the conveying inlet to the conveying outlet, the conveying channel is formed by a first downwardly inclined conveying section and a second horizontally extending conveying section.

[0014] The beneficial effects of this utility model after adopting the above solution are as follows: By setting a peeling component at the conveying outlet of the label roll, the label roll can be bent at an angle after being conveyed to the peeling component. Due to the different stiffness of the label paper and the backing paper, the degree of bending of the label roll can make the label paper and the backing paper bend asynchronously during the continuous conveying of the label roll, thereby peeling the label paper off the backing paper. The conveying roller assembly clamps the peeled backing paper, and the active roller actively rotates to drive the label roll outward, so that the label roll can be taut and continuously conveyed towards the conveying outlet, avoiding slippage during the conveying process, making the conveying smoother, realizing automatic peeling of the label paper, eliminating the need for manual peeling of the label paper, and making it convenient to use.

[0015] In addition, after the label paper is printed, the label paper can be peeled off and pasted in one go. The pressure strip makes the label paper stick tightly to the surface of the object to be pasted, improving work efficiency. Attached Figure Description

Detailed Implementation

[0023] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", "middle", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0025] like Figure 1-6 As shown, this utility model provides an automatic label peeling structure, which is applied to a label printer 400 for peeling off label paper 100. The label roll 200 includes a base paper 300 and label paper 100. Several label papers 100 are sequentially pasted on the outer side of the base paper 300 along the winding direction of the base paper 300. The stiffness of the base paper 300 is different from that of the label paper 100. The structure includes a conveying channel 1, a peeling component 2, and a conveying roller component 3.

[0026] Key points combined Figure 1 As shown, the conveying channel 1 is used to convey the label roll 200 and has a conveying outlet 11 for the label roll 200 to be sent out, as shown. Figure 1 As indicated by the arrow, after the label roll 200 is conveyed out through the conveying channel 1, it is sequentially conveyed to the peeling assembly 2 and the conveying roller assembly 3. The conveying channel 1 is a narrow channel that is only used for conveying the label roll 200. The conveying channel 1 has a conveying inlet 12, which is connected to the paper bin 15. The label roll 200 is placed in the paper bin 15. The conveying inlet 12 is used to feed the label roll 200 in. The conveying channel 1 forms a first downward inclined conveying section 13 and a second horizontally extending conveying section 14 from the conveying inlet 12 to the conveying outlet 11, so that the label roll 200 is output more smoothly.

[0027] In this specific embodiment, the peeling component 2 is located at the conveying outlet 11. After the label roll 200 is conveyed to the peeling component 2, it can be bent at an angle. The degree of angle bending of the label roll 200 can automatically peel the label 100 off the backing paper 300. Since the stiffness of the label 100 and the backing paper 300 are different, their bending resistance is different. When bending at an angle, the label 100 and the backing paper 300 bend asynchronously, and thus the label 100 and the backing paper 300 can be separated. This principle is existing technology and will not be described in detail. Preferably, after the label roll 200 is bent at an angle, the angle between the label roll 200 and the peeled backing paper 300 is an acute angle.

[0028] In this specific embodiment, the conveying roller assembly 3 is spaced apart from the peeling assembly 2 and includes an active roller 4 and a driven roller 5. The active roller 4 and the driven roller 5 are existing roller shafts. The peeled backing paper 300 is clamped between the active roller 4 and the driven roller 5. The active roller 4 rotates actively to feed the backing paper 300 out in the rotation direction and pulls the label roll 200 towards the conveying outlet 11, so that the label roll 200 is continuously conveyed, realizing automatic peeling of the label paper 100. The rotation of the active roller 4 outside the conveying channel 1 pulls the label roll 200, making it easier for the label roll 200 to adhere to the blade 211 and easier to tighten the label roll 200. Compared with the prior art method of pushing the label roll 200 from inside the conveying channel 1 outward, the paper feeding is smoother and less prone to slippage. It can avoid feeding more paper, which would make it difficult for the label roll 200 to adhere to the blade 211. The structure is simpler.

[0029] Key points combined Figure 5-6As shown, the drive roller 4 is connected to a drive assembly 16, which includes a drive motor 161 and a gear transmission assembly 162. The drive motor 161 drives the gear transmission assembly 162 to rotate. The gear transmission assembly 162 includes multiple gears that mesh with each other. A first driven gear 163 is provided at the end of the drive roller 4. The output end of the gear transmission assembly 162 meshes with the first driven gear 163 to drive the first driven gear 163 to rotate actively. The gear transmission assembly 162 then drives the drive roller 4 to rotate. This is prior art and will not be described in detail.

[0030] Key points combined Figure 2 As shown, a guide roller 10 is provided on the bottom side of the conveying channel 1. The guide roller 10 is an existing roller shaft. The top side of the guide roller 10 extends upward into the conveying channel 1 to support the label roll 200. It can guide and tighten the label roll 200, making the label roll 200 output more smoothly. At the same time, the label paper 100 is printed by supporting the label roll 200 with the guide roller 10.

[0031] Preferably, the guide roller 10 can rotate actively to push the label roll 200 towards the conveying outlet 11, forming a pull-push conveying structure with the drive roller 4. Specifically, the end of the guide roller 10 is provided with a second driven gear 164 that meshes with the output end of the gear transmission assembly 162. The output end of the gear transmission assembly 162 is an output gear. By simultaneously meshing the first driven gear 163 and the second driven gear 164 on both sides of an output gear, the first driven gear 163 and the second driven gear 164 can rotate synchronously, so that the guide roller 10 and the drive roller 4 can achieve the same speed to synchronously convey the label roll 200.

[0032] In this specific embodiment, the active roller 4 and the driven roller 5 can be elastically clamped together. This can be achieved by the active roller 4 elastically approaching the driven roller 5, or the driven roller 5 elastically approaching the active roller 4, as long as the peeled bottom paper 300 can be clamped.

[0033] Key points combined Figures 3-5 As shown, it also includes a flap 6, with a pivot point 61 formed in the middle of the flap 6, allowing its two ends to move in opposite directions. The two ends of the flap 6 are a first end 62 and a second end 63, respectively. The first end 62 is used to install the driven roller 5, and a mounting groove 66 for installing the driven roller 5 is formed in the first end 62. The second end 63 forms a pressing part 64. The flap 6 is connected to an elastic element 7, which is used to elastically drive the first end 62 closer to the driving roller 4, so that the driven roller 5 is pressed tightly against the driving roller 4. The pressing part 64 is used for pressing by hand to overcome the elastic force of the elastic element 7, so that the driven roller 5 is moved away from the driving roller 4, and the driven roller 5 and the driving roller 4 are separated. Paper is picked up and put down by pressing, which is more convenient to use and makes it easier to adjust the position of the bottom paper 300.

[0034] In this specific embodiment, the elastic element 7 is a compression spring, installed at the second end 63 of the flap 6, used to press down on the second end 63 with elastic force, causing the flap 6 to rotate around the pivot point 61, thereby driving the driven roller 5 located at the first end 62 to move upward toward the driving roller 4, focusing on the combination of Figure 4 As shown, the pressing part 64 is exposed on the bottom surface of the flip plate 6 and is composed of several strip-shaped protrusions, which are convenient for hand touch and pressing. When the pressing part 64 of the second end 63 is pressed upward, the compression spring can be compressed upward, and the flip plate 6 flips around the rotation fulcrum 61, causing the first end 62 to flip downward, thereby separating the driven roller 5 and the driving roller 4. Of course, in other embodiments, the elastic element 7 can also be a torsion spring, a spring sheet, etc. The specific setting position is not limited, as long as it can elastically drive the first end 62 to approach the driving roller 4.

[0035] In this embodiment, the label printer 400 includes a housing 401, and a flap 6 is pivotally connected to the bottom side of the housing 401. Specifically, the flap 6 is pivotally connected by pivot shafts on both sides of the middle part, and pivot holes are formed on the inner sidewalls of both sides of the housing 401. The pivot shafts are inserted into the pivot holes, so that the flap 6 is pivotally connected to the housing 401. The flap 6 is used as a base plate and also has a bottom paper discharge outlet 65 for feeding the bottom paper 300 downward. The bottom paper 300 is fed downward through the bottom paper discharge outlet 65 and out of the housing 401. A serrated structure is formed on the inner sidewall of the bottom paper discharge outlet 65 for tearing off the bottom paper 300.

[0036] Key points combined Figure 2 As shown, the peeling assembly 2 includes a peeling blade 21, which extends upward at an angle away from the conveying channel 1. The end of the peeling blade 21 forms a pointed blade 211. The conveying roller assembly 3 is located below the peeling blade 21. The label roll 200 is wound around the blade 211 with the backing paper 300 against the peeling blade 21, then turns downward to form an angled bend, and is conveyed at an angle to the conveying roller assembly 3 in the direction of the conveying channel 1. The pointed blade 211 allows the label roll 200 to form a large angle bend after being wound around the blade. After bending, an acute angle is formed between the label roll 200 and the peeled backing paper 300, which facilitates the peeling of the label 100 from the backing paper 300. After peeling, the label side faces upward and the adhesive side faces downward, which makes it convenient to directly stick the object to be pasted from bottom to top on the side of the label 100.

[0037] Key points combined Figure 2 As shown, the peeling assembly 2 also includes a pressing member 8, which is located between the conveying outlet 11 and the peeling blade 21. The pressing member 8 is used to press down the label roll 200, so that the label roll 200 is pressed down and then rolled up around the peeling blade 21. This not only makes the label roll 200 rise at a steeper angle, but also allows the pressing member 8 to press down on one end of the label 100, generating downward pressure at that point, making it easier for the other end of the label 100 conveyed to the blade 211 to separate from the backing paper 300.

[0038] Preferably, a pressure strip 9 is also provided above the conveying outlet 11. The pressure strip 9 extends upward at an angle, and a pressure surface 91 is formed on the bottom side. The pressure surface 91 is used to press the label paper 100. In use, after the label paper 100 is printed, the label paper 100 is conveyed to the blade 211 along with the label roll 200 for peeling. As the drive roller 4 continues to rotate, the peeled bottom paper 300 continues to bend downward, and the bottom surface of the peeled label paper 100 is exposed outside the blade 211. The bottom surface of the label paper 100 is the adhesive surface. After the surface of the object to be pasted is pasted to the side of the bottom surface of the label paper 100, the label surface of the label paper 100 is pressed against the pressure surface 91, so that the label paper 100 is tightly attached to the surface of the object to be pasted. The peeling and pasting of the label paper 100 can be completed in one go, improving work efficiency.

[0039] The above description is only a preferred embodiment of this utility model and is not intended to limit the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
