Description

Technical Field

[0001] The present application relates to the technical field of label production, and in particular, to a misaligned pasting device and a sticker production device. Background Art

[0002] In the existing sticker production and application fields, in order to facilitate manual peeling of the sticker, imprints are usually set on the release paper of the sticker. The imprints are generally set along the outer edge of the sticker to facilitate the user to tear the sticker along the imprints. However, this traditional imprint design has many drawbacks in practical applications, resulting in various problems during the use of the sticker.

[0003] The problems existing in the process of manually peeling the sticker are as follows:

[0004] 1. If the imprint depth is too shallow, it is difficult to provide sufficient friction to effectively separate the paper surface from the release paper; if the imprint depth is too deep, it is easy to cause tearing or damage to the edge of the release paper, affecting the aesthetics and use effect of the paper surface.

[0005] 2. Tearing along the imprint is likely to cause burrs or tearing on the edge of the sticker.

[0006] 3. Due to the difference in the characteristics of the release paper and the paper surface materials, the adhesion between the two is different, and it is easy to cause tearing of the release paper or the paper surface remaining on the release paper when tearing the sticker.

[0007] The problems existing in the process of peeling the sticker by the existing label peeling machine are as follows:

[0008] 1. If the separation force generated by the label peeling machine is less than the adhesion force between the paper surface and the release paper, the peeling of the paper surface and the release paper cannot be achieved, and the purchased finished sticker cannot be used; if the separation force generated by the label peeling machine is too large, it is easy to cause the sticker to break.

[0009] 2. If the imprint depth is too deep, the sticker is likely to break under the pulling of the label peeling machine.

[0010] Therefore, the separation force of the label peeling machine needs to be controlled within a range that is greater than the adhesion force of the sticker and does not cause the release paper to break.

[0011] In order to solve the above problems, there is an urgent need for a device that can effectively solve the problem of difficult peeling of imprint stickers, so as to improve the sticker peeling efficiency, reduce the production cost, and enhance the sticker use experience. Summary of the Invention

[0012] Aiming at the deficiencies of the existing technology, the purpose of the present application is to provide a misaligned pasting device and a sticker production device, which can enhance the experience of peeling the sticker and improve the sticker peeling efficiency.

[0013] The above object of the present application is achieved through the following technical solutions:

[0014] A dislocation pasting device is used for implementing dislocation pasting on stickers. The stickers comprise release paper with imprints and a plurality of paper surfaces arranged on the release paper.

[0015] Furthermore, the offset pasting device includes: a conveying structure for supporting a first area of the sticker, a peeling structure for peeling off the paper surface and the release paper, an operating space for operating the release paper alone, and a receiving structure for realizing offset pasting of the paper surface and the imprint on the release paper in a second area.

[0016] Furthermore, the conveying structure, the stripping structure and the receiving structure are arranged in sequence, a gap is provided between the stripping structure and the receiving structure, and the operating space is provided below the gap.

[0017] Furthermore, the conveying structure and the receiving structure tension the release paper located therebetween.

[0018] Furthermore, the conveying structure is configured to transfer the sticker from the first area to the second area.

[0019] By adopting the above technical scheme, the efficiency of peeling off the sticker can be significantly improved. The paper surface and the release paper are peeled off through the peeling structure, and then the paper surface and the release paper are re-laminated through the receiving structure. The sticker is re-laminated after being peeled off once, which reduces the peeling resistance and makes it easier to separate. Since the paper surface and the release paper are staggered when they are re-laminated, there is no need to tear the paper surface along the edge of the imprint when using it, which effectively prevents the release paper from being torn or damaged along the edge of the imprint or the edges of the paper surface from being burred or torn.

[0020] The present application is further configured such that the stripping structure has a first end face pointing to the receiving structure and a second end face pointing to the operating space, and the first end face and the second end face are connected by a turning point.

[0021] The present application is further configured such that one end of the second end surface is connected to the first end surface, and the other end of the second end surface extends obliquely in a direction opposite to the receiving structure.

[0022] The present application is further configured such that the first end surface and the second end surface are connected via a turning portion having an arc.

[0023] The present application is further configured such that at least one operating roller is provided in the operating space, and the release paper passes around the operating roller.

[0024] The present application is further configured such that the running roller is located below the gap and near one side of the conveying structure, and the tangent line formed from the turning portion to the running roller is the release paper running line, and the release paper running line fits against the second end face or forms an acute angle with the second end face.

[0025] The present application is further configured to further include a pressing device having a third end face, and the third end face and the first end face press both sides of the sticker.

[0026] The present application is further configured such that the receiving structure includes one or more receiving rollers, and the first end face is flush with the upper surface of the receiving roller.

[0027] A sticker production device includes the above-mentioned misaligned pasting device, and further includes a sticker manufacturing device located at the front end of the misaligned pasting device and a sticker winding device located at the rear end of the misaligned pasting device.

[0028] Adopting the above technical solution, the misaligned pasting is placed between the sticker manufacturing device and the sticker winding device. During the production process, if the paper surface cannot be separated from the release paper, it indicates that the adhesion between the release paper and the paper surface is too strong or the imprint is too light. By observing the separation effect, improvements can be made in a timely manner to ensure product quality.

[0029] In summary, the beneficial technical effects of the present application are as follows:

[0030] 1. The present application realizes the peeling of the paper surface and the release paper through the peeling structure, and then realizes the re - fitting of the paper surface and the release paper through the receiving structure. After the sticker is peeled off and then re - fitted once, the peeling resistance is reduced and it is easier to separate, facilitating the peeling of the sticker by manual and label stripping machines; the sticking force of the sticker is reduced, enabling a wider selection range for the separation force of the label stripping machine.

[0031] 2. By setting the peeling structure and the receiving structure, when the paper surface and the release paper are re - fitted, the paper surface and the imprint are misaligned. When the user uses it, there is no need to tear the paper surface along the edge of the imprint, effectively preventing the paper surface from being torn or damaged along the edge of the imprint or the occurrence of frayed edges or tears at the edge of the paper surface. During the use of manual and label stripping machines, the situation of release paper tearing and paper surface frayed edges is reduced, improving the yield rate.

[0032] 3. Since the sticker is peeled off and re - pasted once in the present application, the peeling resistance is reduced, and the sticker can be peeled off from the release paper more quickly, improving the peeling efficiency, which is especially suitable for mass production and usage scenarios.

[0033] 4. The offset pasting of the present application is placed between the sticker manufacturing device and the sticker winding device. During the production process, if the paper surface cannot be separated from the release paper, it means that the adhesion between the release paper and the paper surface is too strong or the imprint is too shallow. By observing the separation effect, timely improvements can be made to ensure product quality. The adhesion can be controlled during the production process to avoid the situation where the finished product is difficult to peel off after production. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The present application is further described in detail below in conjunction with the accompanying drawings.

[0040] like Figures 1-2 As shown, an offset pasting device is used for offset pasting of a sticker T. The sticker T includes a release paper with an imprint and a paper surface arranged on the release paper. The type of sticker T facing the offset pasting device is that the imprint on the release paper matches the outer contour of the paper surface. The offset pasting device separates the paper surface and the release paper, and then pastes the paper surface to a position offset from the imprint on the release paper, thereby achieving offset pasting.

[0041] Specifically, the offset pasting device includes: a conveying structure 1 for supporting a first area X of a sticker T, a peeling structure 2 for peeling off a paper surface and a release paper, an operating space Z for operating the release paper alone, and a receiving structure 3 for realizing offset pasting of the paper surface and the print on the release paper in a second area Y.

[0042] Furthermore, the conveying structure 1 and the receiving structure 3 tighten the release paper between them.

[0043] Furthermore, the conveying structure 1 is configured to transfer the sticker T from the first area X to the second area Y.

[0044] Regarding the conveying structure 1, it is only used as a structure for conveying the stickers T and providing power, that is, any structure that can provide power for conveying the stickers T can be used; preferably, the conveying structure 1 includes a structure formed by a combination of a power roller and a power component in Chinese authorized utility model patent CN212798971U; preferably, the conveying structure 1 includes a structure formed by a combination of a power roller and a servo motor in Chinese authorized utility model patent CN214354299U.

[0045] Regarding the receiving structure 3, it is only used as a structure for receiving, conveying, and tensioning the release paper, and for pasting the sticker T and the release paper, preferably as follows Figure 1 As shown, the receiving structure 3 includes one or more receiving rollers for receiving the release paper. Regarding the tensioning function of the receiving structure 3, preferably, the structure of the first-stage tensioning roller or the second-stage tensioning roller in the Chinese utility model patent CN215248528U can be selected; preferably, the structure of the tensioning roller group in the Chinese utility model patent CN206705353U can also be selected.

[0046] The above examples are only used to illustrate that the specific structures and principles of the conveying structure 1 and the receiving structure 3 are conventional technical means in this field. The specific principles refer to the above examples and conventional technologies in this field and will not be elaborated here.

[0047] Furthermore, the conveying structure 1 , the peeling structure 2 and the receiving structure 3 are arranged in sequence, a gap J is provided between the peeling structure 2 and the receiving structure 3 , and the operating space Z is provided below the gap J.

[0048] The present application separates the paper surface and the release paper once through the peeling structure 2 and the receiving structure 3, and it is easier to peel off after the separation. Since the device separates the paper surface and the release paper at the peeling structure 2, and the release paper operates independently in the operating space Z, it is re-attached at the receiving structure 3, making it easier to peel off the paper surface later.

[0049] The present application separates the paper surface and the release paper once through the peeling structure 2 and the receiving structure 3. When re-pasting, the paper surface and the imprint are staggered, which makes it easier to peel off and is not prone to tearing or breaking along the edge of the imprint. The offset pasting device realizes the offset pasting of the paper surface and the imprint on the release paper through the receiving mechanism, so that the paper surface and the imprint are staggered, avoiding the problem of tearing or breaking when the traditional paper surface is peeled off along the imprint, improving the peeling effect and service life of the paper surface, and because it is easy to peel off, it is not easy to cause burrs or tears on the edge of the paper surface.

[0050] It is worth mentioning that there are at least two ways of offset pasting. One is that the paper covers the imprint when the sticker T is peeled off. At this time, the release paper is bent along the imprint and the paper will easily lift up. The other is that the imprint is in front of the paper when the sticker T is peeled off. At this time, the paper will easily lift up when it is bent to the inside of the imprint. Both of the above methods avoid the problem caused by the edge of the paper and the imprint matching.

[0051] like Figure 2 As shown, the stripping structure 2 has a first end surface 21 pointing to the receiving structure 3 and a second end surface 22 pointing to the operating space Z, and the first end surface 21 and the second end surface 22 are connected in a turning manner.

[0052] Furthermore, one end of the second end surface 22 is connected to the first end surface 21 , and the other end of the second end surface 22 extends obliquely in a direction opposite to the receiving structure 3 .

[0053] Furthermore, a turning portion is formed at the connection between the first end surface 21 and the second end surface 22 .

[0054] The peeling structure 2 of the present application separates the paper surface and the release paper more effectively. During the process of conveying the sticker T from the first end surface 21 to the second end surface 22, the direction of the release paper transportation changes at the turning point. Since the paper surface is harder than the release paper, it will continue to move along the direction of the first end surface 21 due to inertia, thereby separating from the release paper.

[0055] Specifically, when the paper surface is transported at the first end surface 21, its moving direction is consistent with that of the release paper. When the paper surface reaches the turning portion, the direction of the release paper transportation changes and moves in the direction close to the second end surface 22. The direction changes. However, the paper surface will continue to move in the direction of the first end surface 21. This difference in direction causes the separation of the paper surface and the release paper.

[0056] The second end face 22 of the peeling structure 2 is inclined so that the release paper is deflected toward the inclination direction of the second end face 22 during the peeling process and is finally guided to the operating space Z. The inclined design of the second end face 22 effectively guides the release paper into the operating space Z, preventing the release paper from folding or piling up in the operating space Z, thereby ensuring the smooth operation of the release paper.

[0057] Furthermore, the turning portion has an arc, and the size of the arc is selected according to the width of the gap J and the length of the paper surface. The design of the turning portion having an arc can protect the release paper from scratches and scrapes, and prevent the release paper from breaking.

[0058] like Figure 2 As shown, at least one running roller 4 is provided in the running space Z, and the release paper passes around the running roller 4 .

[0059] Furthermore, the running roller 4 is located below the gap J and close to the side of the conveying structure 1. The tangent line formed from the turning part to the running roller 4 is the release paper direction line. The release paper direction line is attached to the second end surface 22 or has an acute angle with the second end surface 22. This arrangement will make the sticker T form as follows Figure 1 The direction in the middle, the release paper is arranged obliquely in the operating space Z in order to save space and make the release paper run more smoothly.

[0060] Specifically, there are two tangent lines formed from the turning portion to the running roller 4, which are as follows: Figure 1 The middle sticker T is shown as a line formed between the tangent point and the turning part on the roller away from the receiving structure 3.

[0061] Furthermore, the offset pasting device further comprises a pressing device 5 , wherein the pressing device 5 has a third end surface 51 , and the third end surface 51 and the first end surface 21 press the two sides of the paper sticker T tightly.

[0062] Preferably, the third end surface 51 and the first end surface 21 are arranged opposite to or in parallel, the third end surface 51 is against the paper surface of the sticker T, and the first end surface 21 is against the release paper of the sticker T.

[0063] More preferably, see Figure 2 The pressing device 5 also has a fourth end face 52, the third end face 51 is connected to the fourth end face 52, the connection between the third end face 51 and the fourth end face 52 is against the paper surface of the sticker T, and the first end face 21 is against the release paper of the sticker T.

[0064] The pressing device 5 serves to press the tail of the paper surface when the paper surface passes through the turning portion, so that the head of the paper surface does not deflect in the direction of the release paper.

[0065] The pressing device 5 also includes a connecting rod, a rotating shaft 53 and a limiting portion 54. The third end face 51 and the fourth end face 52 are both arranged on the connecting rod. The rotating shaft 53 is connected to the connecting rod. The connecting rod can rotate around the rotating shaft 53, which is convenient for adjusting the degree of compression of the sticker T and also convenient for the installation of the sticker T in the offset pasting device. The limiting portion 54 is used to fix the connecting rod and the external assembly frame 7 to ensure the stability of the pressing device 5 and better realize the compression work.

[0066] like Figures 1-3 As shown, the receiving structure 3 includes one or more receiving rollers, and the first end surface 21 is flush with the upper surface of the receiving roller.

[0067] The receiving structure 3 also includes a flattening device, preferably two rollers arranged opposite to each other, so that the pasted sticker T passes between the two rollers to ensure the adhesion of the pasted sticker.

[0068] In addition, the misaligned pasting device further includes an adjusting structure 6, which includes a mounting portion 61, a pulling rod 62, a fixing rod 63, a manual adjusting portion 64, and an assisting portion 65. The running roller 4 is installed on the mounting portion 61, and the mounting portion 61 is connected to the pulling rod 62. The pulling rod 62 can adjust the position of the running roller 4 in the Figure 1 vertical direction, and the fixing rod 63 is used to fix the mounting portion 61 and the external assembly frame 7. The manual adjusting portion 64 is connected to the upper end of the pulling rod 62 for convenient manual adjustment by the user. The assisting portion 65 is fixed on the external assembly frame 7, and the pulling rod 62 passes through the assisting portion 65, and the assisting portion 65 plays an assisting role in the movement of the pulling rod 62.

[0069] A sticker production device includes the above-mentioned misaligned pasting device, and further includes a sticker manufacturing device located at the front end of the misaligned pasting device and a sticker winding device located at the rear end of the misaligned pasting device.

[0070] The sticker manufacturing device is used to produce stickers T with imprints that match the edges of the paper surface, and the sticker manufacturing device also includes printing on the paper surface pattern.

[0071] The formation methods of the imprints include but are not limited to die cutting and stamping.

[0072] Specifically, the sticker manufacturing device can select a device that realizes the preparation method of transfer stickers in Chinese Patent Application CN117774539A; or it can also select a device that realizes the label manufacturing method in Chinese Patent Application CN104321190A.

[0073] The sticker winding device is used to wind the misaligned stickers to form products. Preferably, a device for manufacturing a roll of release paper that is convenient for winding and recycling in Chinese Patent Document CN220264564U can be selected; preferably, a winding roller for winding release paper with different width specifications in Chinese Patent Document CN219792035U can also be selected.

[0074] Taking the above examples as illustrations, the specific structures and principles of the sticker manufacturing device and the sticker winding device are conventional technical means in the field. For their specific principles, refer to the above examples and the conventional techniques in the field, and no further elaboration will be made here.

[0075] As Figures 3-4 shown, the misaligned pasting device is installed on the outer shell 8 through the assembly frame 7. The assembly frame 7 includes end plates 71 and edges 72. The two end plates 71 are provided on both sides of the misaligned pasting device, and the end plates 71 are installed on the outer shell 8. Each edge 72 is connected to one end plate 71 to form an angle and is stuck on the outer shell 8 to form a stable connection relationship.

[0076] The end plate 71 is provided with a slide groove 73 and a positioning hole 74 . The slide groove 73 is used for sliding insertion of the stripping structure 2 and the receiving structure 3 . The various components of the offset pasting device are limited to positions suitable for production on the end plate 71 through the positioning holes 74 .

[0077] By achieving one-time separation during the production process, problems can be discovered and solved in time. If the paper surface and the release paper cannot be completely separated during one separation process, it means that the adhesion between the release paper and the paper surface is too strong or the imprint is too shallow. Improvements can be made in time at the sticker manufacturing device, such as adjusting the material of the release paper, the depth of the imprint, the viscosity of the sticker T, etc., to ensure the smooth progress of the production process.

[0078] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
