Description

Technical Field

[0001] The present invention relates to the technical field of transfer paper conveying, and specifically to a positioning lithography device for the production of positioning lithography transfer paper for cigarette packs with lithographed cat's eyes. Background Technique

[0002] Transfer paper, also known as transition paper, can print patterns onto the surface of an object. After being heated, the printed pattern can be transferred to the object's surface. The pattern texture is clear and the fidelity is high. A cat's eye coating can be attached to it. It is a packaging material for cigarettes. Its production process needs to go through processes such as printing, bronzing, punching, and slitting. With the continuous development of society, it is no longer limited to simple packaging, but pays more attention to decoration, anti-counterfeiting, and environmental protection.

[0003] During the production process of cigarette pack transfer paper, before entering the lithography process, it needs to be transported by a conveyor using the method of winding and unwinding. Since transfer paper is a low-gram-weight paper, during the graphic transfer processes such as printing and bronzing, due to factors such as tension and vibration, the conveying rollers are prone to vibrate and shift. During the conveying process of the transfer paper, when it enters the positioning lithography process, the offset problem of the conveying rollers is likely to cause inaccurate lithography positions and deformed pattern characters. At this time, it is necessary to correct the deviation of the conveying rollers in a timely manner to ensure that the transfer paper is conveyed in the middle position of the conveying system to achieve the positioning function. However, when maintenance personnel adjust the position of the conveying rollers by adopting traditional deviation correction measures, it is easy to cause the deviation of the transfer paper itself. After correcting the position of the conveying rollers, it is also necessary to check the position of the transfer paper itself. Therefore, when the existing positioning lithography device conveys the transfer paper into the lithography process, in terms of ensuring the quality of the later pattern formation, the operation is not efficient enough, the conveying deviation correction operation is relatively complex and not convenient enough, and it needs to be improved in the actual application process. Summary of the Invention

[0004] The purpose of the present invention is to provide a positioning lithography device for the production of positioning lithography transfer paper for cigarette packs with lithographed cat's eyes, which has the effect of facilitating the deviation correction operation of maintenance personnel and ensuring that the transfer paper is conveyed in the middle during lithography, and solves the problems mentioned in the above background technique.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A positioning lithography device for the production of positioning lithography transfer paper for cigarette packs with lithographed cat's eyes, including a lithography machine and a conveyor device. The conveyor device includes a conveying roller body and a correction roller arranged in front of the lithography machine.

[0007] Optionally, the offset sensing device includes a photoelectric detection board. Two fixing blocks are fixedly connected to the surface of the lithography machine. The photoelectric detection board is arranged on the opposite surfaces of the two fixing blocks. Force sensors are arranged at both ends inside the conveying roller body.

A deflection rod is fixedly connected to the outer wall of the internal gear ring. An arc-shaped groove is formed in the surface of the mechanical housing. The deflection rod passes through the arc-shaped groove. The correction roller is rotatably connected to the end of the deflection rod.

[0009] Optionally, the regulating component includes a connecting sleeve which is rotatably connected to the shaft wall of the driving shaft. Two fixed shafts are fixedly connected to the surface of the connecting sleeve. Four limiting rods are slidably connected to the inner wall of the mechanical housing. Springs are sleeved on the rod walls of the four limiting rods. The ends of the four limiting rods are fixedly connected together to form a rectangular frame. Two adjusting grooves are formed on the surface of the rectangular frame. The two fixed shafts respectively pass through the two adjusting grooves. A sleeve is slidably connected to the shaft wall of the driving shaft in a spline manner. The sleeve is rotatably connected to the inner wall of the mechanical housing. An adjusting gear is fixedly connected to the outer wall of the sleeve. A straight-tooth cylinder is fixedly connected to the shaft wall of the transmission shaft. A sliding opening for the displacement of the transmission shaft is formed on the surface of the mechanical housing. A connecting component is fixedly connected to the top surface of the rectangular frame. Two shaft bodies I are fixedly connected to the inner wall of the connecting component. Two openings for the transmission shaft to pass through are formed on the surface of the connecting component. A spiral groove is formed on the shaft wall of the transmission shaft. The rod walls of the two shaft bodies I are both slidably connected to the groove wall of the spiral groove.

[0010] Optionally, the locking component includes a pressing rod which is slidably connected to the inner wall of the driving shaft. A locking spring is fixedly connected to the end of the pressing rod. The end of the locking spring is fixedly connected to the inner wall of the driving shaft. An inclined groove is formed on the rod wall of the pressing rod. A clamping rod is slidably connected to the shaft wall of the driving shaft. A shaft body II is fixedly connected to the surface of the clamping rod. The shaft body II is slidably connected to the groove wall of the inclined groove.

[0011] Optionally, anti-slip patterns are formed on the surface of the deviation-correcting torsion fixedly connected to the shaft wall of the driving shaft.

[0012] Optionally, the size of the adjusting gear is adapted to the size of the straight-tooth cylinder, and the size of the spiral groove is adapted to the size of the two shaft bodies I.

[0013] Optionally, the axial length of the correcting roller is greater than the axial length of the conveying roller body, and the position of the conveying roller body is adapted to the position of the correcting roller.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] First, through the cooperation of structures such as the control gear, the control rod and the internal gear ring, before deviation correction, the correcting roller deflects and contacts the transfer paper, and the conveying roller body moves vertically downward to disengage from the transfer paper, which avoids the defect that when the conveying roller body is corrected for deviation, it drives the transfer paper to move synchronously, thereby causing the deviation of the position of the transfer paper itself.

[0016] At the same time, in this way, compared with some traditional methods where the transfer paper is directly lifted and then corrected for deviation, this method does not directly drive the tipping paper to move upward and separate from the conveying roller body. Instead, after taking over the supporting condition of the conveying roller body, the conveying roller body moves downward for deviation correction. This move avoids the process of actively lifting the transfer paper. During the deviation correction process, the transfer paper itself is not affected by external forces, thereby further avoiding the displacement of the transfer paper itself.

[0017] Second, when the present invention performs deviation correction operations, maintenance personnel can complete the entire process of deviation correction work by operating a drive shaft, improving the practicality of the device. And through the cooperation of structures such as a rectangular frame, a straight-tooth cylinder, and a spiral groove, during deviation correction, due to the existence of the spiral groove, the axial displacement speed of the transmission shaft is still relatively small. Therefore, precise control of the movement of the conveying roller body can be achieved. Compared with traditional methods, in this method, when maintenance personnel perform deviation correction adjustments, it can be more convenient without worrying about the problem of difficult alignment.

[0018] Third, through the cooperation of structures such as an adjusting gear, a locking spring, and a clamping rod in the present invention, when maintenance personnel adjust the axial position of the conveying roller body, they do not need to always maintain a state of overcoming the elastic force. Thus, when personnel correct the deviation of the axial position of the conveying roller body, it can also be more precise and labor-saving. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Example 1. Please refer to Figures 1 to 8 , the present invention provides a positioning lithography device for the production of a positioning lithography cat's eye transfer paper for cigarette packs, including a lithography machine 1 and a conveyor device 201. The conveyor device 201 includes a conveying roller body 2 and a correction roller 3 arranged in front of the lithography machine 1. An offset sensing device is arranged on the surface of the lithography machine 1, and deviation rectifying components are arranged on both sides of the conveying roller body 2.

[0029] The deviation rectifying component includes: a mechanical shell 4, a conveying replacement component, a regulating component, and a locking component. The mechanical shell 4 is fixedly connected to the surface of the lithography machine 1. A transmission shaft 5 is arranged inside the mechanical shell 4. The conveying roller body 2 is installed at the end of the transmission shaft 5 through a mounting bracket. A baffle 36 is fixedly connected to the inner wall of the mechanical shell 4. A driving shaft 6 is sleeved on the inner wall of the baffle 36. The conveying replacement component is arranged inside the mechanical shell 4. The regulating component is in transmission connection with the conveying replacement component, and the locking component is in transmission connection with the conveying replacement component.

[0030] Among them, the offset sensing device includes:

[0031] A photoelectric detection board 7. Two fixing blocks 8 are fixedly connected to the surface of the lithography machine 1. The photoelectric detection board 7 is arranged on the opposite surfaces of the two fixing blocks 8. Force sensors 9 are arranged at both ends inside the conveying roller body 2.

[0032] The conveying replacement component includes: a slider 10. The slider 10 is rotatably connected to the shaft wall of the driving shaft 6. Sliding rods 11 are fixedly connected to the top and bottom surfaces of the slider 10. Two sliding grooves 12 are opened on the inner wall of the mechanical shell 4. The rod walls of the two sliding rods 11 are respectively slidably connected to the groove walls of the two sliding grooves 12. A control rod 13 is fixedly connected to the surface of the slider 10. A tooth block 14 is fixedly connected to the end of the control rod 13. A fixing plate 15 is fixedly connected to the inner wall of the mechanical shell 4. An internal gear ring 16 is rotatably connected to the inner wall of the fixing plate 15. A control gear 17 is fixedly connected to the shaft wall of the driving shaft 6. A deflection rod 18 is fixedly connected to the outer wall of the internal gear ring 16. An arc-shaped groove is opened on the surface of the mechanical shell 4. The deflection rod 18 passes through the arc-shaped groove. The correction roller 3 is rotatably connected to the end of the deflection rod 18.

[0033] A deviation rectifying torsion 37 is fixedly connected to the shaft wall of the driving shaft 6. Anti-slip lines are arranged on the surface of the deviation rectifying torsion 37.

[0034] In this embodiment, during the production of cigarette pack transfer paper, a cat's eye laser effect is embossed and ultraviolet cured during the UV transfer coating process, and then a metallic aluminum layer is deposited on the UV transfer coating layer by vacuum plating to form a cat's eye transfer film layer with an anti-counterfeiting effect. Then, it is bonded to the cigarette pack production paper through an adhesive to form a special transfer paper for cigarette packs with a cat's eye pattern anti-counterfeiting mark. Subsequently, the transfer paper is transported into the lithography machine through a transport device for positioning lithography, that is, the transfer paper is positioned and transported by the conveyor device 201. During the transportation of the transfer paper, since the transfer paper is a low-gram-weight paper, it is prone to vibration offset of the conveying roller body 2 itself due to factors such as tension and vibration. After the transfer paper passes through the conveying roller body 2, when the conveying roller body 2 vibrates and offsets, it will contact the force sensor 9 on the offset side, causing the force sensor 9 on this side to send a signal to the photoelectric detection board 7. At this time, since no signal is transmitted from the force sensor 9 on the other side, the photoelectric detection board 7 will display a state of uneven numerical values, thereby determining that the conveying roller body 2 vibrates and offsets. At this time, when it is determined that there is a vibration offset, the device automatically stops, and then the transportation of the transfer paper is adjusted to ensure that the transfer paper is located in the middle area of the conveying device.

[0035] After stopping the transportation of the transfer paper, when the maintenance personnel reach the maintenance position, they can first axially move the drive shaft 6, so that the drive shaft 6 drives the slider 10 to perform axial displacement. Through the axial displacement of the slider 10, the two slide rods 11 and the control rod 13 will be synchronously driven to displace, and at the same time, the control gear 17 will be driven to displace synchronously. Through the axial displacement of the control gear 17, it first meshes with the teeth of the internal gear ring 16. At this time, by rotating the drive shaft 6, the control gear 17 will rotate, and then through the transmission of the control gear 17, the internal gear ring 16 will deflect, so that the deflection rod 18 deflects with the drive shaft 6 as the axis, and thus the correction roller 3 performs a circular trajectory displacement. When the correction roller 3 performs a circular displacement and contacts the transfer paper and is at the same height as the conveying roller body 2, then the drive shaft 6 can be axially moved again, so that the control gear 17 continues to perform axial displacement, causing its teeth to disengage from the teeth of the internal gear ring 16, and the rear tooth block 14 meshes with the teeth of the internal gear ring 16. When the drive shaft 6 performs axial displacement, the slider 10, the two slide rods 11, the control rod 13, and the tooth block 14 displace synchronously, that is, the two slide rods 11 slide along the walls of the two chutes 12 respectively. After the tooth block 14 meshes with the teeth of the internal gear ring 16, the state of the internal gear ring 16 can be locked at this time, that is, the correction roller 3 is kept in this state unchanged.

[0036] In the above manner, before deviation correction, the deflection of the correction roller 3 can be used to contact the transfer paper when it reaches the same horizontal line as the conveying roller body 2, providing a preliminary preparation for the subsequent deviation correction adjustment of the conveying roller body 2 and avoiding affecting the offset of the transfer paper itself when correcting the deviation of the conveying roller body 2.

[0037] Embodiment 2, on the basis of the above embodiment:

[0038] Please refer to Figures 1 to 7 , the regulating component includes a connecting sleeve 19 which is rotatably connected to the shaft wall of the driving shaft 6. Two fixed shafts 20 are fixedly connected to the surface of the connecting sleeve 19. Four limiting rods 21 are slidably connected to the inner wall of the mechanical housing 4. Springs 22 are sleeved on the rod walls of the four limiting rods 21. The ends of the four limiting rods 21 are commonly fixedly connected to a rectangular frame 23. Two adjusting grooves 24 are formed on the surface of the rectangular frame 23. The two fixed shafts 20 respectively pass through the two adjusting grooves 24. A sleeve 25 is spline-slidably connected to the shaft wall of the driving shaft 6. The sleeve 25 is rotatably connected to the inner wall of the mechanical housing 4. An adjusting gear 26 is fixedly connected to the outer wall of the sleeve 25. A straight-tooth cylinder 27 is fixedly connected to the shaft wall of the transmission shaft 5. A sliding opening for the displacement of the transmission shaft 5 is formed on the surface of the mechanical housing 4. A connecting component 28 is fixedly connected to the top surface of the rectangular frame 23. Two shaft bodies 29 are fixedly connected to the inner wall of the connecting component 28. Two openings for the transmission shaft 5 to pass through are formed on the surface of the connecting component 28. A spiral groove 30 is formed on the shaft wall of the transmission shaft 5. The rod walls of the two shaft bodies 29 are both slidably connected to the groove wall of the spiral groove 30.

[0039] In this embodiment, during the first movement of the drive shaft 6 by the maintenance personnel mentioned above, the connecting sleeve 19 will be synchronously driven to displace. At the same time, as can be seen from the figure, the two fixed shafts 20 will be axially displaced, so that the two fixed shafts 20 will slide along the horizontal grooves on the two adjusting grooves 24 respectively. After the control gear 17 meshes with the teeth of the internal gear ring 16, at this time, the fixed shaft 20 is located at the intersection of the horizontal groove and the inclined groove on the adjusting groove 24. After the deflection of the correcting roller 3 is completed, when the drive shaft 6 is axially moved again at this time, the fixed shaft will slide along the inclined groove on the adjusting groove 24, so that during this process, the rectangular frame 23 will move vertically downward. During the vertical downward movement of the rectangular frame 23, the four limiting rods 21 will be synchronously driven to move vertically downward. At this time, the four springs 22 are compressed. When the rectangular frame 23 moves vertically downward, through the transmission of the connecting component 28, the transmission shaft 5 will move vertically downward. Through the transmission of the transmission shaft 5, the offset conveying roller body 2 can be moved vertically downward to disengage from the transfer paper. At the same time, when the transmission shaft 5 moves vertically downward, the straight-tooth cylinder 27 will also be moved vertically downward to mesh with the teeth of the adjusting gear 26. At this time, when the drive shaft 6 is rotated again, through the transmission of the adjusting gear 26, the straight-tooth cylinder 27 will be rotated. Through the rotation of the straight-tooth cylinder 27, the transmission shaft 5 will be rotated. During the rotation of the transmission shaft 5, the spiral groove 30 on it will be rotated. Since the groove wall of the spiral groove 30 is restricted by the two shaft bodies I 29 and the two shaft bodies I 29 cannot perform circumferential displacement, during the rotation of the transmission shaft 5, it will perform axial displacement. Through the axial displacement of the transmission shaft 5, the conveying roller body 2 installed on it can be axially displaced, so as to complete the deviation correction adjustment of the position of the conveying roller body 2 until the transfer paper is again located in the middle area of the conveying roller body 2. During the process of the conveying roller body 2 being corrected for deviation, since it first moves vertically downward and has disengaged from the transfer paper, the rotation of the conveying roller body 2 driven by the mounting frame during this process will not cause any impact.

[0040] By adopting the above method, first before deviation correction, through the deflection of the correcting roller 3, when it reaches the same horizontal line as the conveying roller body 2, it contacts the transfer paper, and then the conveying roller body 2 moves vertically downward to disengage from the transfer paper. This move can utilize the characteristic of the sequence to avoid the defect that when the conveying roller body 2 is corrected for deviation, it drives the transfer paper to move synchronously, thereby causing the deviation of the position of the transfer paper itself.

[0041] At the same time, through this method, compared with some traditional methods in which the deviation correction component is moved to directly lift the transfer paper, this method does not directly drive the tipping paper to move upward and disengage from the conveying roller body 2. Instead, after taking over the supporting condition of the conveying roller body 2, the conveying roller body 2 moves downward for deviation correction. This move avoids the process of actively lifting the transfer paper, and the transfer paper itself is not affected by external forces during the deviation correction process, thus further avoiding the displacement of the transfer paper itself.

[0042] Moreover, when performing the rectification operation of the above process, whether it is the deflection of the correction roller 3 or the rectification work of the conveying roller body 2, both are driven by the movement of the drive shaft 6. The maintenance personnel only need to operate on one place during the rectification process, which is more convenient to use, has strong practicability. And it should be noted that when rectifying the conveying roller body 2, its axial displacement utilizes the characteristics of the spiral groove 30. Therefore, during the rectification process, although the cross-sectional radius of the straight-tooth cylinder 27 is relatively smaller than that of the adjusting gear 26, due to the existence of the spiral groove 30, the axial displacement speed of the transmission shaft 5 is still small, so as to realize precise control of the movement of the conveying roller body 2. The maintenance personnel are more convenient to operate and have better effects during the rectification adjustment.

[0043] Embodiment 3, on the basis of the above embodiment:

[0044] Please refer to Figures 4 to 8 , the locking component includes a pressing rod 31, the pressing rod 31 is slidably connected to the inner wall of the drive shaft 6, the end of the pressing rod 31 is fixedly connected with a locking spring 32, the end of the locking spring 32 is fixedly connected with the inner wall of the drive shaft 6, an inclined groove 33 is formed on the rod wall of the pressing rod 31, a clamping rod 34 is slidably connected to the shaft wall of the drive shaft 6, and a second shaft body 35 is fixedly connected to the surface of the clamping rod 34, and the second shaft body 35 is slidably connected to the groove wall of the inclined groove 33.

[0045] In this embodiment, during the process of driving the drive shaft 6 for the second-stage axial displacement in the above process, that is, when driving the straight-tooth cylinder 27 to mesh with the adjusting gear 26, since it is in a state of overcoming the elastic force of the spring 22 at this time, the maintenance personnel can press the pressing rod 31 at this time, so that the pressing rod 31 undergoes axial displacement, so that the locking spring 32 is compressed. Subsequently, through the synchronous displacement of the inclined groove 33, the second shaft body 35 slides along the groove wall of the inclined groove 33, so that the clamping rod 34 moves vertically downward and extends into the drive shaft 6. After the straight-tooth cylinder 27 meshes with the adjusting gear 26, the maintenance personnel release the pressing finger at this time, so that the pressing rod 31 automatically returns to its original position. At this time, under the elastic action of the locking spring 32, the clamping rod 34 will move vertically upward and extend into the cavity in the baffle 36. At this time, the drive shaft 6 can be prevented from performing axial displacement reset through the baffle 36. And during the subsequent rectification process, the rotation of the drive shaft 6 will cause the clamping rod 34 to perform circular displacement in the cavity, that is, it does not affect the rotation of the drive shaft 6.

[0046] In the above way, when adjusting the axial position of the conveying roller body 2, the maintenance personnel do not need to maintain the state of overcoming the elasticity of the spring 22, so that the personnel can be more precise and labor-saving when rectifying the axial position of the conveying roller body 2, and the practical effect is further improved.

[0047] Working principle: During the production of cigarette pack transfer paper, first, a cat's eye laser effect is embossed during the UV transfer coating process and ultraviolet curing is carried out. Then, a metal aluminum layer is deposited on the UV transfer coating layer by means of vacuum plating to form a cat's eye transfer film layer with anti-counterfeiting effect. Then, it is bonded to the cigarette pack production paper through an adhesive to form a special transfer paper for cigarette packs with a cat's eye pattern anti-counterfeiting mark. Subsequently, the transfer paper is conveyed by a conveyor device 201 and conveyed into a lithography machine for positioning lithography. During the conveyance of the transfer paper, since the transfer paper is a low-gram-weight paper, it is prone to vibration offset of the conveying roller body 2 itself due to factors such as tension and vibration. When the conveying roller body 2 vibrates and offsets, it will contact the force sensor 9 on the offset side, causing the force sensor 9 on this side to send a signal to the photoelectric detection board 7. At this time, since no signal is transmitted from the force sensor 9 on the other side, the photoelectric detection board 7 will display a state of uneven numerical values, thus determining that the conveying roller body 2 vibrates and offsets. At this time, the conveyance of the transfer paper is stopped for adjustment;

[0048] During adjustment, maintenance personnel can first move the drive shaft 6 to make the control gear 17 mesh with the teeth of the internal gear ring 16. Then, rotate the drive shaft 6 to make the correction roller 3 perform a circumferential trajectory displacement. When the correction roller 3 is displaced circumferentially and contacts the transfer paper and is at the same height as the conveying roller body 2, then the drive shaft 6 can be pushed again to make the control gear 17 continue to perform an axial displacement to lock the position of the correction roller 3. At the same time as the locking is completed, the conveying roller body 2 moves vertically downward to disengage from the transfer paper. Then, rotate the drive shaft 6 again to make the conveying roller body 2 perform an axial displacement, thereby completing the deviation correction adjustment of the position of the conveying roller body 2 until the transfer paper is again located in the middle area of the conveying roller body 2, and the positioning deviation correction work can be completed.
