Description

Technical Field

[0001] The present application relates to the technical field of sticker production, and particularly to a sticker production system. 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] 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 appearance and use effect of the paper surface. Tearing along the imprint is likely to cause burrs or tearing at the edge of the sticker. Due to the different 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.

[0004] To solve the problem of difficult peeling of imprinted stickers, it is necessary to set the imprint and the paper surface part out of alignment. However, to perform misaligned pasting, it is necessary to move the sticker smoothly.

[0005] Currently, in the sticker printing process, we usually adopt intermittent printing. The sticker is driven by a pull head to move into the color group, and then the sticker is printed. To achieve seamless docking of the printed patterns on the sticker, the intermittent printing method is usually adopted. That is to say, after the pull head drives the sticker forward into the printing machine for printing one pattern, it will drive the sticker to move backward to make the sticker retreat a certain distance, and then move forward for printing the next pattern. In this state, the sticker cannot be misaligned and pasted when moving back and forth.

[0006] To solve the above problems, there is an urgent need for a device that is applicable to the existing intermittent printing and can effectively solve the problem of difficult peeling of imprinted stickers, so as to improve the sticker peeling efficiency, reduce the production cost, and enhance the sticker use experience. Summary of the Invention

[0007] Aiming at the deficiencies of the existing technology, the purpose of the present application is to provide a sticker production system that can be applicable to the existing intermittent printing device and can effectively solve the problem of difficult peeling of imprinted stickers.

[0008] The above object of the present application is achieved through the following technical solutions:

[0009] A sticker production system is used to produce stickers, wherein the stickers include release paper with an imprint and a plurality of paper surfaces arranged on the release paper. The sticker production system includes a sticker printing device for printing patterns on the paper surfaces. The sticker printing device includes a first state for driving the sticker forward and a second state for driving the sticker backward during a printing operation.

[0010] The sticker production system further comprises a printing tensioning device for tensioning the sticker, wherein the printing tensioning device has an active roller moving along the forward or backward direction of the sticker, and the sticker bypasses the active roller.

[0011] The sticker production system also includes an offset pasting device for achieving offset pasting of the sticker, the offset pasting device having a peeling structure for peeling off the release paper and the paper surface, an operating space for independently operating the release paper, and a receiving structure for achieving offset pasting of the paper surface and the imprint on the release paper.

[0012] The sticker production system also includes a rolling device for rolling the sticker into a roll.

[0013] The sticker printing device, the printing tensioning device, the offset pasting device and the winding device are sequentially arranged on the path where the sticker runs.

[0014] The present application is further configured such that the sticker production system also includes a waste collecting device, which is arranged between the printing tensioning device and the offset pasting device, and includes a separation roller and a receiving roller arranged at the rear end of the separation roller along a first path and a waste roller arranged at the rear end of the separation roller along a second path, the waste on the sticker moves along the second path, and the waste roller reels up the waste.

[0015] The present application is further configured such that the first path is arranged along a substantially horizontal direction, and an acute angle is formed between the second path and the first path.

[0016] The present application is further configured such that the waste roller is arranged above the winding device.

[0017] The present application is further configured such that the sticker production system also includes a smoothing device, which is arranged between the offset pasting device and the winding device, and has a bottom roller and a pressure roller arranged opposite to each other, and the bottom roller and the pressure roller press the two sides of the sticker.

[0018] The present application is further configured such that the sticker production system also includes a slitting device for cutting the stickers, and the slitting device is arranged between the flattening device and the winding device.

[0019] The present application is further configured such that the sticker production system further includes a plurality of tension rollers, and the tension rollers are distributed in the printing tensioning device and the offset pasting device.

[0020] The present application is further configured such that a sticker manufacturing device is provided at the front end of the sticker printing device, and the sticker manufacturing device includes an impression cutting device, and the impression cutting device cuts the paper surface and forms an impression on the release paper.

[0021] The present application is further configured such that the sticker production system also includes an outer frame, the printing tensioning device, the offset pasting device and the winding device are all arranged on the outer frame, and the printing tensioning device is arranged below the offset pasting device.

[0022] In summary, the beneficial technical effects of this application are:

[0023] 1. The present application provides an offset pasting device to achieve offset pasting of the release paper and the print on the paper surface, which solves the problem that the print is usually set on the edge of the paper surface, which is easy to cause burrs, tears, and even paper residue on the release paper when torn off. It improves the user experience and the efficiency of sticker peeling, and users can peel off stickers more easily and completely, reducing the scrapping of stickers caused by tearing, burrs and other problems.

[0024] 2. The present application sets a printing tensioning device in front of the offset pasting device, which can effectively tension the sticker and ensure that the sticker remains smooth during the printing process, providing favorable conditions for the realization of offset pasting.

This avoids the problem of paper surface remaining on the release paper when traditional imprint stickers are torn, improves the integrity of sticker peeling, avoids paper surface residue, and improves the sticker usage experience.

Detailed implementation manners

[0037] The following further describes the present application in detail with reference to the accompanying drawings.

[0038] As Figure 1 shown, a sticker production system is shown for producing a sticker T, and the sticker T is as Figure 6 shown. The sticker T includes a release paper T2 with imprints and a paper surface T1 provided on the release paper T2, and the imprints on the release paper T2 match the outer contour of the paper surface T1.

[0039] Specifically, the sticker production system includes a sticker printing device for printing patterns on the paper surface T1. When performing a printing operation, the sticker printing device includes a first state in which the sticker T is driven forward and a second state in which the sticker T is driven backward, that is, the sticker printing device uses an intermittent printing method for printing. A control device for multi-color overprinting applicable to intermittent printing equipment in a Chinese invention publication document with the application number: CN103182837B can be selected; a environmentally friendly and energy-saving intermittent printing equipment in a Chinese utility model patent document with the application number: CN219276978U can also be selected.

[0040] Taking the above examples is only to illustrate the specific structure and principle of the sticker printing device, which are conventional technical means in the field. For the specific principle, refer to the above examples and the conventional techniques in the field, and will not be elaborated here.

[0041] The sticker production system further includes a printing tensioning device A for tensioning the sticker T. The printing tensioning device A has a movable roller 11 that moves along the forward or backward direction of the sticker T. The sticker T bypasses the movable roller 11, and the movable roller 11 tensions the sticker T in one of the first state or the second state.

[0042] Specifically, referring to Figures 2 to 4 , the printing tensioning device A further includes a sliding structure 13. The sliding mechanism is arranged along the forward or backward direction of the sticker T, and the movable roller 11 is slidably arranged on the sliding structure 13.

[0043] The printing tensioning device A further includes a feedback component 12. The feedback component 12 drives the movable roller 11 to slide along the sliding structure 13 in the other state of the first state or the second state to tension the sticker T.

[0044] Through the coordinated work of the movable roller 11, the sliding structure 13 and the feedback component 12, dynamic tensioning in the forward and backward states of the sticker T is achieved, improving the printing accuracy and stability.

[0045] In a preferred embodiment, the feedback component 12 includes a tension sensor and a moving component. The tension sensor detects the tension of the sticker T on the movable roller 11. The tension sensor is connected to the moving component, and the moving component drives the movable roller 11 to slide along the sliding structure 13.

[0046] Preferably, the moving component is selected as a cylinder, which expands and contracts to drive the movable roller 11 to slide along the sliding structure 13. More preferably, the moving component is selected as a hydraulic cylinder, which expands and contracts to drive the movable roller 11 to slide along the sliding structure 13.

[0047] Preferably, the tension sensor can be the tension sensor in a blended yarn production device of a Chinese invention application with the publication number CN118651726A; preferably, the tension sensor can also be the tension sensor in a yarn unwinding mechanism for a sectional warping machine of a Chinese utility model patent with the publication number CN221480201U.

[0048] Taking the above examples is only to illustrate that the specific structure and principle of the tension sensor are conventional technical means in the art, and only the tension received by the sensing sticker T needs to be sensed. For its specific principle, refer to the above examples and the conventional techniques in the art, and no further elaboration will be made here.

[0049] During the forward or backward movement of the sticker T, the movable roller 11 will automatically adjust its position according to the signal of the feedback component 12, and always maintain an appropriate tension on the sticker T. This can effectively avoid the situation of the sticker T being slack or too tight during the movement, thereby improving the printing accuracy and stability and reducing printing defects.

[0050] In another preferred embodiment, the feedback component 12 includes a printing action detection device and a moving component. The printing action detection device detects the action of the sticker printing device, and then obtains the forward or backward state of the sticker T. The printing action detection device feeds back the forward or backward state of the sticker T to the moving component, and the moving component drives the movable roller 11 to slide along the sliding structure 13.

[0051] Preferably, the moving component is selected as a cylinder, which expands and contracts and drives the movable roller 11 to slide along the sliding structure 13. More preferably, the moving component is selected as a hydraulic cylinder, which expands and contracts and drives the movable roller 11 to slide along the sliding structure 13.

[0052] It should be noted that the sticker T bypasses the movable roller 11 and deflects its moving direction, and the deflection angle of the moving direction is not less than 90°.

[0053] As Figure 3 shown, the structure of Embodiment 1 of the printing tension device A is shown. The feedback component 12 includes two mounting brackets 121 and two springs 122. The two mounting brackets 121 are respectively connected to both sides of the movable roller 11. One end of each spring 122 is fixedly arranged, and the other end of each spring 122 is connected to a mounting bracket 121.

[0054] The mounting bracket 121 has a vertical plate and a plurality of horizontal plates. The plurality of horizontal plates are all connected to the vertical plate. The other end of the spring 122 is connected to the vertical plate, and the movable roller 11 is connected to the horizontal plate.

[0055] Preferably, in the first state, the spring 122 undergoes elastic deformation, that is, when the sticker T moves forward, the spring 122 is compressed, and when the sticker T moves backward, the spring 122 is in its natural state.

[0056] Preferably, in the second state, the spring 122 undergoes elastic deformation, that is, when the sticker T moves backward, the spring 122 is stretched, and when the sticker T moves forward, the spring 122 is in its natural state.

[0057] Preferably, in the first state and the second state, the spring 122 undergoes elastic deformation, that is, when the sticker T moves forward, the spring 122 is compressed, and when the sticker T moves backward, the spring 122 is stretched, and the spring 122 is in a state between the two in its natural state.

[0058] Specifically, by limiting the stroke of the movable roller 11 sliding along the sliding structure 13, it can be limited that when the sticker T moves forward, the movable roller 11 will move to the end point of the stroke. At this time, the position of the movable roller 11 can be limited when the sticker T moves forward, and the spring 122 will not deform due to the forward movement of the sticker T. Similarly, by limiting that the movable roller 11 will move to the end point of the stroke when the sticker T moves backward, the position of the movable roller 11 can also be limited when the sticker T moves backward, and the spring 122 will not deform due to the backward movement of the sticker T.

[0059] The forward and backward directions of the above-mentioned sticker T are as Figure 2 shown, Figure 1 The direction indicated by the arrow on the sticker printing device in is the forward direction of the sticker T, and the direction opposite to it is the backward direction of the sticker T.

[0060] The spring 122 undergoes elastic deformation when the sticker T moves forward or backward, providing a tension force, achieving precise control of the tension force of the sticker T. Using the spring 122 for dynamic adjustment can effectively prevent the sticker T from becoming loose or too tight during movement, thereby improving printing accuracy and stability and reducing printing defects. Especially in the case of large changes in printing speed or uneven thickness of the sticker T, this dynamic adjustment function is even more important and can effectively ensure printing quality.

[0061] Compared with other feedback components 12, this design has a simple structure, is easy to manufacture and install, and can effectively reduce costs. At the same time, this design uses the spring 122 as a feedback element, which has good durability and reliability and can effectively reduce maintenance costs.

[0062] Through the dynamic adjustment function of the spring 122, this feedback component 12 does not require manual intervention to adjust the tension force, simplifies the operation, and improves the operation convenience. At the same time, due to its dynamic adjustment function, it can adapt to the needs of different stickers T and different printing speeds, improving the versatility and flexibility of the printing equipment.

[0063] Furthermore, the power for driving the sticker T to move backward by the sticker printing device is greater than the elastic force of the spring 122.

[0064] Furthermore, the sliding structure 13 includes a sliding cover 131 and a convex rail 132. The convex rail 132 is fixedly arranged along the advancing or retracting direction of the sticker T. The sliding cover 131 is fixedly arranged on the mounting bracket 121. The sliding cover 131 is in a lid shape and is slidably mounted on the convex rail 132.

[0065] Furthermore, there are two sliding covers 131 and two convex rails 132 respectively. The two sliding covers 131 are respectively connected to the side walls of the two mounting brackets 121 opposite to the movable roller 11. Each sliding cover 131 cooperates with one convex rail 132.

[0066] In a preferred embodiment, balls are arranged inside the sliding cover 131, and rolling cooperation is achieved through the balls and the convex rail 132.

[0067] As Figure 4 shown, the structure of Embodiment 2 of the printing tensioning device A is shown. The feedback assembly 12 includes two elastic members 123. One ends of the two elastic members 123 are fixedly arranged, and the other ends of the two elastic members 123 are respectively connected to both ends of the movable roller 11. The sliding structure 13 includes two sliders 133 and two slide rails 134. The two slide rails 134 are along the advancing or retracting direction of the sticker T. The two sliders 133 are respectively fixedly connected to both ends of the movable roller 11. Each slider 133 is slidably arranged in one slide rail 134.

[0068] The deformation of the elastic member 123 can automatically adjust the position of the movable roller 11 according to the movement state of the sticker T, and always maintain an appropriate tension force on the sticker T. The slider 133 slides in the slide rail 134, which can effectively prevent the movable roller 11 from jamming or jumping during the movement process, thereby improving the printing accuracy and stability and reducing printing defects.

[0069] Adopting the flexible design of the elastic member 123 can effectively buffer the impact force of the sticker T during the movement process and reduce the risk of printing damage. The cooperation between the slider 133 and the slide rail 134 can achieve the smooth sliding of the movable roller 11 and avoid the excessive stretching or damage caused by the traditional fixed tensioning method.

[0070] The sticker printing device uses an intermittent printing method to print patterns on the paper surface T1 of the sticker T. The backward movement generated by the sticker T during the printing process will affect the flatness and efficiency of winding. The printing tensioning device A effectively offsets this backward movement, facilitating the subsequent operations and improving the production efficiency.

[0071] The sticker production system further includes a misalignment pasting device B for realizing the misalignment pasting of the sticker T.

[0072] As Figures 6 to 10As shown, the specific structure of the offset pasting device B is shown. The type of sticker T facing the offset pasting device B is that the imprint on the release paper T2 matches the outer contour of the paper surface T1. The offset pasting device B separates the paper surface T1 and the release paper T2, and then copies the paper surface T1 to a position offset from the imprint on the release paper T2 to achieve offset pasting.

[0073] Specifically, the offset pasting device B includes: a peeling structure 2 for peeling the paper surface T1 and the release paper T2, an operating space Z for independently operating the release paper T2, and a receiving structure 3 for realizing offset pasting of the prints on the paper surface T1 and the release paper T2.

[0074] The receiving structure 3 includes a receiving position C for receiving the release paper T2, which only serves as a structure for receiving, conveying, tensioning, and pasting the sticker T and the release paper T2. Preferably, as shown in the figure, the receiving structure 3 includes one or more receiving rollers D4 for receiving the release paper T2.

[0075] Furthermore, the peeling structure 2 and the receiving structure 3 are arranged in sequence, with a gap J between the peeling structure 2 and the receiving structure 3 , and the operating space Z is arranged below the gap J.

[0076] The present application separates the paper surface T1 and the release paper T2 once through the peeling structure 2 and the receiving structure 3, and it is easier to peel off after separation. Because the device separates the paper surface T1 and the release paper T2 at the peeling structure 2, and the release paper T2 operates alone in the operating space Z, and is re-attached at the receiving structure 3, it is easier to peel off the paper surface T1 subsequently.

[0077] The present application separates the paper surface T1 and the release paper T2 once through the peeling structure 2 and the receiving structure 3. When re-pasting, the paper surface T1 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 B realizes the offset pasting of the paper surface T1 and the imprint on the release paper T2 through the receiving mechanism, so that the paper surface T1 is staggered with the imprint, avoiding the problem of tearing or breaking when the traditional paper surface T1 is peeled off along the imprint, thereby improving the peeling effect and service life of the paper surface T1. Since it is easy to peel off, it is not easy to cause burrs or tears on the edge of the paper surface T1.

[0078] It is worth mentioning that there are at least two ways of offset pasting. One is that the paper surface T1 covers the imprint when the sticker T is peeled off. At this time, the release paper T2 is bent along the imprint, and the paper surface T1 will easily lift up. The other is that the imprint is in front of the paper surface T1 when the sticker T is peeled off. At this time, the paper surface T1 will easily lift up when it is bent to the inside of the imprint. The above two methods avoid the problem caused by the edge of the paper surface T1 and the imprint matching.

[0079] like Figure 7As shown, the peeling structure 2 has a first end face 21 arranged along the first direction F1 in the figure, that is, pointing to the receiving structure 3, and a second end face 22 arranged along the second direction F2 in the figure, that is, pointing to the operating space Z. The first end face 21 and the second end face 22 are connected by a turn.

[0080] Furthermore, one end of the second end face 22 is connected to the first end face 21, and the other end of the second end face 22 extends obliquely in a direction opposite to the receiving structure 3.

[0081] Furthermore, a turning portion is formed at the connection between the first end face 21 and the second end face 22.

[0082] The peeling structure 2 of the present application separates the paper surface T1 and the release paper T2 more effectively. During the process of the sticker T being conveyed from the first end face 21 to the second end face 22, at the turning portion, the transport direction of the release paper T2 changes, while the paper surface T1, due to its hardness being greater than that of the release paper T2, will continue to move along the direction of the first end face 21 due to inertia, thus separating from the release paper T2.

[0083] Specifically, when the paper surface T1 is conveyed on the first end face 21, its movement direction is the same as that of the release paper T2. When the paper surface T1 reaches the turning portion, the transport direction of the release paper T2 changes and it moves along the direction close to the second end face 22, and the direction changes. However, the paper surface T1 will still continue to move along the direction of the first end face 21, and this difference in direction leads to the separation of the paper surface T1 and the release paper T2.

[0084] The second end face 22 of the peeling structure 2 is obliquely designed, so that the release paper T2 deflects in the direction of the inclination of the second end face 22 during the peeling process and is finally guided to the operating space Z. Moreover, the oblique design of the second end face 22 effectively guides the release paper T2 into the operating space Z, preventing the release paper T2 from folding or piling up in the operating space Z and ensuring the smooth operation of the release paper T2.

[0085] Furthermore, the turning portion has a radian. The size of the radian is selected according to the width of the gap J and the length of the paper surface T1. The design of the turning portion having a radian can protect the release paper T2 from scratches and abrasions and avoid the breakage of the release paper T2.

[0086] As Figure 7 shown, at least one operating roller 4 is provided in the operating space Z, and the release paper T2 bypasses the operating roller 4.

[0087] Further, the running roller 4 is located on the side away from the receiving structure 33 below the gap J. The tangent line formed from the turning part to the running roller 4 is the running direction line of the release paper T2. The running direction line of the release paper T2 is attached to the second end face 22 or forms an acute angle with the second end face 22. Such a setting will make the sticker T form the running direction as shown in the figure. The release paper T2 is obliquely arranged in the running space Z to save space and make the running of the release paper T2 smoother.

[0088] Specifically, there are two tangent lines formed from the turning part to the running roller 4. Here, it refers to Figure 7 as shown by the running direction of the sticker T in the figure, that is, the connection line formed between the tangent point on the roller away from the receiving structure 3 and the turning part.

[0089] Further, the misaligned pasting device B further includes a pressing device 5. The pressing device 5 has a third end face 51, and the third end face 51 and the first end face 21 press both sides of the sticker T.

[0090] Preferably, the third end face 51 and the first end face 21 are oppositely arranged or parallelly arranged. The third end face 51 abuts against the paper surface T1 of the sticker T, and the first end face 21 abuts against the release paper T2 of the sticker T.

[0091] More preferably, referring to Figure 8 , the pressing device 5 further has a fourth end face 52. The third end face 51 and the fourth end face 52 are connected. The connection part between the third end face 51 and the fourth end face 52 abuts against the paper surface T1 of the sticker T, and the first end face 21 abuts against the release paper T2 of the sticker T.

[0092] The function of the pressing device 5 is to press the tail of the paper surface T1 when the paper surface T1 passes through the turning part, so that the head of the paper surface T1 does not follow the release paper T2 to deflect in direction.

[0093] The pressing device 5 further includes a connecting rod, a rotating shaft 53 and a limiting part 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 pressing degree of the sticker T and also convenient for the installation of the sticker T in the misaligned pasting device B. The limiting part 54 is used to fix the connecting rod and the external assembling frame 7 to ensure the stability of the pressing device 5 and better realize the pressing work.

[0094] In addition, the misaligned pasting device B further includes an adjusting structure 6. The adjusting structure 6 includes a mounting part 61, a pulling rod 62, a fixing rod 63, a manual adjusting part 64 and an auxiliary part 65. The running roller 4 is installed on the mounting part 61. The mounting part 61 is connected to the pulling rod 62. The pulling rod 62 can make the running roller 4 Figure 7The position adjustment in the upper and lower directions, the fixing rod 63 is used to fix the mounting part 61 and the external assembly frame 7, the manual adjustment part 64 is connected to the upper end of the pull rod 62 to facilitate manual adjustment by the user, the auxiliary part 65 is fixed on the external assembly frame 7, the pull rod 62 passes through the auxiliary part 65, and the auxiliary part 65 plays an auxiliary role in the movement of the pull rod 62.

[0095] The sticker production system also includes a winding device I for winding the sticker T into a roll; the sticker T winding device I is used to roll up the dislocated sticker T to form a product. Preferably, a device for making a roll of release paper T2 that is easy to roll and recycle in Chinese patent document CN220264564U can be selected; preferably, a winding roller that can adapt to the winding of release paper T2 of different width specifications in Chinese patent document CN219792035U can also be selected.

[0096] The above examples are only used to illustrate that the specific structure and principle of the sticker manufacturing device and the sticker T winding device I 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 repeated here.

[0097] Specifically, the sticker printing device, the printing tensioning device A, the offset pasting device B and the winding device I are sequentially arranged on the path of the sticker T.

[0098] The printing tensioning device A is suitable for existing intermittent printing, and the offset pasting device B is compatible with the intermittent sticker printing device. The offset pasting function can be realized without changing the existing printing equipment, which is convenient for practical application and reduces production costs.

[0099] The offset pasting design makes the sticker T easier to peel off, which provides a better user experience and avoids the problems of tearing and rough edges of traditional imprint sticker T, making the sticker T more beautiful and neat, thus improving the user experience.

[0100] During the process of offset pasting, peeling off the sticker once and then re-pasting can improve the peeling efficiency, and the sticker T can be peeled off more easily and completely, making it more convenient and comfortable to use, thereby improving user satisfaction with the product.

[0101] The sticker production system also includes a waste collection device D, such as Figure 1 and Figure 5 As shown, the waste collecting device D is arranged between the printing tensioning device A and the offset pasting device B. The waste collecting device D includes a separation roller D1 and a receiving roller D4 arranged along the first path D3 at the rear end of the separation roller D1, and a waste roller E arranged along the second path D2. The waste on the sticker T moves along the second path D2, and the waste roller E reels the waste.

[0102] The first path D3 is arranged in a substantially horizontal direction, and there is an acute angle between the second path D2 and the first path D3.

[0103] As Figure 1 shown, the first path D3 is along Figure 1 the direction that generally runs from left to right in Figure 1 , and the second path D2 is along the direction that generally runs from the lower left to the upper right in Figure 1 . Their trending directions are both from left to right, and the included angle is an acute angle. Such an arrangement can apply the inertia of the movement of the sticker T to the waste material, making it easier to achieve separation.

[0104] Furthermore, the waste material roller E is arranged above the winding device I, and the separation roller D1 is arranged on one side of the waste material roller E and the winding device I. Such a structure is more compact, saves space, and is convenient for the user to take away the waste material formed by the waste material roller E and the product wound by the winding device I.

[0105] The sticker production system further includes a flattening device G. The flattening device G is arranged between the misaligned pasting device B and the winding device I. The flattening device G has a bottom roller G1 and a pressure roller G2 arranged oppositely. The bottom roller G1 and the pressure roller G2 press both sides of the sticker T, and are used to flatten and press the paper surface T1 and the release paper T2 that are re - attached after passing through the misaligned pasting device B.

[0106] The sticker production system further includes a slitting device H for cutting the sticker T. The slitting device H is arranged between the flattening device G and the winding device I, and is used to cut off the sticker T after a roll of product is produced. A cutting knife that moves along the width direction of the sticker T can be selected, and only the function of cutting off the sticker T needs to be realized.

[0107] The sticker production system further includes a plurality of tension rollers L. The tension rollers L are distributed in the printing tension device A and the misaligned pasting device B, and are used to tension the sticker T.

[0108] A sticker manufacturing device is provided at the front end of the sticker printing device. The sticker manufacturing device includes an imprint cutting device. The imprint cutting device cuts the paper surface T1 and forms an imprint on the release paper T2.

[0109] The sticker manufacturing device is used to produce a sticker T with an imprint that coincides with the edge of the paper surface T1. The forming method of the imprint includes but is not limited to die - cutting and stamping.

[0110] Specifically, the sticker manufacturing device can select a device that realizes the preparation method of the transfer sticker in Chinese Patent Application CN117774539A; or a device that realizes the label manufacturing method in Chinese Patent Application CN104321190A.

[0111] The sticker production system further includes an outer frame. The printing tension device A, the offset pasting device B, and the winding device I are all arranged on the outer frame, and the printing tension device A is arranged below the offset pasting device B.

[0112] Furthermore, the outer frame includes an assembly frame 7 and a housing 8. As Figures 9 to 10 shown, the offset pasting device B is installed on the housing 8 through the assembly frame 7. The assembly frame 7 includes end plates 71 and edges 72. The two end plates 71 are arranged on both sides of the offset pasting device B, and the end plates 71 are installed on the housing 8. Each edge 72 is connected to one end plate 71 to form an included angle that is stuck on the housing 8 to form a stable connection relationship.

[0113] Chute 73 and positioning holes 74 are provided on the end plate 71. The chute 73 is used for the peeling structure 2 and the receiving structure 3 to slide and insert. Each component on the offset pasting device B is defined on the end plate 71 at a suitable position for production through the positioning holes 74.

[0114] The embodiments of the specific implementation manners are all preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
