Description

Technical Field

[0001] The invention relates to the technical field of transfer paper conveying, in particular to a positioning photolithography device for producing cigarette package photolithography cat's eye positioning transfer paper. Background Art

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

[0003] In the production process of cigarette pack transfer paper, before entering the photolithography process, it needs to be transported by a conveyor in a winding and unwinding manner. Since transfer paper is a low-weight paper, it is easy for the conveyor roller to vibrate and deviate due to factors such as tension and vibration during the printing, hot stamping and other graphic transfer processes. In the conveying process of the transfer paper, when it enters the positioning photolithography process, the offset problem of the conveyor roller is prone to inaccurate photolithography position and deformation of pattern text. At this time, the conveyor roller needs to be corrected in time to ensure that the transfer paper is in the middle position of the conveying system for transmission to achieve the positioning function. When maintenance personnel take traditional correction measures to adjust the position of the conveyor roller, it is easy to cause the transfer paper itself to deviate. After correcting the position of the conveyor roller, it is also necessary to check the position of the transfer paper itself. Therefore, when the transfer paper is conveyed into the photolithography process, the existing positioning photolithography device is not efficient enough in ensuring the quality of the later pattern forming. The conveying correction operation is relatively complicated and inconvenient, and needs to be improved in actual application. Summary of the invention

[0009] Optionally, the locking component includes a pressing rod, which is slidably connected to the inner wall of the driving shaft, and the end of the pressing rod is fixedly connected to a locking spring, and the end of the locking spring is fixedly connected to the inner wall of the driving shaft. The rod wall of the pressing rod is provided with an oblique groove, and the shaft wall of the driving shaft is slidably connected to a clamping rod, and the surface of the clamping rod is fixedly connected to a shaft body 2, and the shaft body 2 is slidably connected to the groove wall of the oblique groove.

[0010] Optionally, a deflection-correcting twist knob is fixedly connected to the shaft wall of the driving shaft, and the surface of the deflection-correcting twist knob is provided with anti-slip patterns.

[0012] Optionally, the axial length of the correction 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 correction roller.

[0013] Compared with the prior art, the present invention has the following beneficial effects: First, the present invention cooperates with structures such as control gears, control rods and internal gear rings, and deflects the correction roller before the deviation is corrected. When the correction roller contacts the transfer paper, the conveying roller body moves vertically downward and breaks away from the contact with the transfer paper. This avoids the defect that the transfer paper is driven to move synchronously when the conveying roller body is corrected, thereby causing the position of the transfer paper to shift. At the same time, compared with some traditional methods that directly lift the transfer paper and then correct it, this method does not directly drive the tipping paper to move up and away from the conveying roller body. Instead, after taking over the support conditions of the conveying roller body, the conveying roller body moves down to correct the deviation. This avoids the process of actively lifting the transfer paper. During the correction process, the transfer paper itself is not affected by external forces, thereby further avoiding the displacement of the transfer paper itself.

[0014] 2. When the present invention is performing a deviation correction operation, the maintenance personnel can complete the whole process of deviation correction by operating a driving shaft, so the practicability of the device is improved. Moreover, through the coordination of structures such as a rectangular frame, a spur cylinder and a spiral groove, when correcting the deviation, due to the existence of the spiral groove, the axial displacement speed of the transmission shaft is still relatively small, so that the movement of the conveying roller body can be accurately controlled. Compared with the traditional method, this method is more convenient for maintenance personnel to perform deviation correction adjustments without worrying about the problem of difficulty in alignment.

[0015] 3. The present invention coordinates the structures such as the adjusting gear, the locking spring and the clamping rod, so that the maintenance personnel do not need to always keep overcoming the elastic force when adjusting the axial position of the conveying roller body, so that the personnel can be more precise and save more effort when correcting the axial position of the conveying roller body.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] For example, see Figures 1 to 8 The present invention provides a positioning photolithography device for producing cat's eye positioning transfer paper for cigarette pack photolithography, comprising a photolithography machine 1 and a conveyor device 201, wherein the conveyor device 201 comprises a conveying roller body 2 and a correction roller 3 arranged in front of the photolithography machine 1, an offset sensing device is arranged on the surface of the photolithography machine 1, and correction components are arranged on both sides of the conveying roller body 2.

[0019] The correction component includes: a mechanical shell 4, a conveying replacement component, an adjusting 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 on the end of the transmission shaft 5 through a mounting frame. 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 in the mechanical shell 4. The adjusting component is transmission-connected to the conveying replacement component. The locking component is transmission-connected to the conveying replacement component.

[0020] The offset sensing device includes: The photoelectric detection board 7 and the surface of the photolithography machine 1 are fixedly connected with two fixing blocks 8 , the photoelectric detection board 7 is arranged on the opposite sides of the two fixing blocks 8 , and force sensors 9 are arranged at both ends of the inner side of the conveying roller body 2 .

[0021] The conveying replacement parts include: a slider 10, which is rotatably connected to the shaft wall of the driving shaft 6, and the top and bottom surfaces of the slider 10 are fixedly connected with a sliding rod 11. The inner wall of the mechanical housing 4 is provided with two sliding grooves 12, and the rod walls of the two sliding rods 11 are respectively slidably connected to the groove walls of the two sliding grooves 12. The surface of the slider 10 is fixedly connected with a control rod 13, and the end of the control rod 13 is fixedly connected with a tooth block 14. The inner wall of the mechanical housing 4 is fixedly connected with a fixed plate 15, and the inner wall of the fixed plate 15 is rotatably connected with an inner gear ring 16. The shaft wall of the driving shaft 6 is fixedly connected with a control gear 17, and the outer wall of the inner gear ring 16 is fixedly connected with a deflection rod 18. The surface of the mechanical housing 4 is provided with an arc groove, and the deflection rod 18 passes through the arc groove, and the correction roller 3 is rotatably connected to the end of the deflection rod 18.

[0022] The shaft wall of the driving shaft 6 is fixedly connected with a deflection-correcting knob 37 , and the surface of the deflection-correcting knob 37 is provided with anti-slip patterns.

[0023] In this embodiment, in the production process of cigarette pack transfer paper, a cat's eye laser effect is first molded out in the UV transfer coating process and UV-cured, and then a metal aluminum layer is plated on the UV transfer coating layer by vacuum plating to form a cat's eye transfer film layer with an anti-counterfeiting effect, and then it is bonded to the cigarette pack production paper by an adhesive to form a special transfer paper for cigarette packs with a cat's eye pattern anti-counterfeiting mark. The transfer paper is then transported into the photolithography machine through a transportation device for positioning photolithography, that is, the transfer paper is positioned and transported by the conveyor device 201. In the process of the transfer paper being transported, since the transfer paper is a low-weight paper, it is easy to be stretched due to tension. , vibration and other factors cause the conveying roller body 2 to vibrate and deviate. After the transfer paper passes through the conveying roller body 2, when the conveying roller body 2 vibrates and deviates, it will contact the force sensor 9 on the deviated side, so that the force sensor 9 on this side sends a signal to the photoelectric detection board 7. At this time, since there is no signal from the force sensor 9 on the other side, the photoelectric detection board 7 will display an uneven value state, and it is determined that the conveying roller body 2 is vibrating and deviating. At this time, when it is determined to be vibrating and deviating, the equipment automatically stops, and then the conveying of the transfer paper is adjusted to ensure that the transfer paper is located in the middle area of ​​the conveying device.

[0024] After stopping the transfer paper conveying, the maintenance personnel arrive at the maintenance position and can first axially move the drive shaft 6 so that the drive shaft 6 drives the slider 10 to perform axial displacement. The axial displacement of the slider 10 will synchronously drive the two slide bars 11 and the control rod 13 to perform synchronous displacement. At the same time, the control gear 17 is driven to perform synchronous displacement. Through the axial displacement of the control gear 17, it first meshes with the teeth of the inner gear ring 16. At this time, the drive shaft 6 is rotated to make the control gear 17 rotate, and then the transmission of the control gear 17 makes the inner gear ring 16 deflect, so that the deflection rod 18 deflects with the drive shaft 6 as the axis, so that the correction roller 3 performs a circular orbit. When the correction roller 3 is displaced circumferentially to contact the transfer paper and is at the same height as the conveying roller body 2, the drive shaft 6 can be axially moved again to allow the control gear 17 to continue to be displaced axially, so that its teeth are disengaged from the teeth of the inner gear ring 16, and the rear tooth block 14 is meshed with the teeth of the inner gear ring 16. When the drive shaft 6 is axially displaced, the slider 10, the two slide bars 11, the control rod 13 and the tooth block 14 are displaced synchronously, that is, the two slide bars 11 slide along the groove walls of the two slide grooves 12 respectively, and after the tooth block 14 is meshed with the teeth of the inner gear ring 16, the state of the inner gear ring 16 can be locked, so that the correction roller 3 remains in this state unchanged.

[0025] Through the above method, it can be achieved that before the deviation correction, the correction roller 3 is deflected so that it contacts the transfer paper when it reaches the same horizontal line with the conveying roller body 2, thereby providing advance preparation for the subsequent deviation correction adjustment of the conveying roller body 2 and avoiding the deviation of the transfer paper itself being affected when the conveying roller body 2 is corrected.

[0026] Embodiment 2, based on the above embodiment: See also 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 limit rods 21 are slidably connected to the inner wall of the mechanical housing 4. The rod walls of the four limit rods 21 are all sleeved with springs 22. The ends of the four limit rods 21 are commonly fixedly connected to a rectangular frame 23. Two adjusting grooves 24 are provided on the surface of the rectangular frame 23. The two fixed shafts 20 pass through the two adjusting grooves 24 respectively. The shaft wall of the driving shaft 6 is spline-type slidably connected with a sleeve 25. The sleeve 25 is rotatably connected to the inner wall of the mechanical housing 4. Connected to the inner wall of the mechanical housing 4, the outer wall of the sleeve 25 is fixedly connected with an adjusting gear 26, the shaft wall of the transmission shaft 5 is fixedly connected with a spur cylinder 27, the surface of the mechanical housing 4 is provided with a sliding opening for the displacement of the transmission shaft 5, the top surface of the rectangular frame 23 is fixedly connected with a connecting component 28, the inner wall of the connecting component 28 is fixedly connected with two shaft bodies 29, the surface of the connecting component 28 is provided with two openings for the transmission shaft 5 to pass through, the shaft wall of the transmission shaft 5 is provided with a spiral groove 30, and the shaft walls of the two shaft bodies 29 are slidably connected to the groove wall of the spiral groove 30.

[0027] In this embodiment, during the first movement of the driving shaft 6 by the maintenance personnel, the connecting sleeve 19 will be synchronously driven to move. 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 is meshed with the teeth of the inner gear ring 16, 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 locking of the correction roller 3 is completed, when the driving shaft 6 is axially moved again, the fixed shaft will slide along the inclined groove on the adjusting groove 24, so that during this process, the rectangular frame 23 moves vertically downward. During the vertical downward movement of the rectangular frame 23, the four limit rods 21 are synchronously driven to move vertically downward. At this time, the four springs 22 are compressed. When the rectangular frame 23 moves vertically downward, the transmission shaft 5 will be moved vertically downward through the transmission of the connecting assembly 28. Through the transmission of the transmission shaft 5, the offset conveying roller body 2 can be moved vertically downward to match the transfer paper The transmission shaft 5 is disengaged from the contact. At the same time, when the transmission shaft 5 moves vertically downward, the spur cylinder 27 is also moved vertically downward to mesh with the teeth of the adjusting gear 26. At this time, the driving shaft 6 is rotated again, and the spur cylinder 27 is rotated through the transmission of the adjusting gear 26. The rotation of the spur cylinder 27 will cause the transmission shaft 5 to rotate. During the rotation of the transmission shaft 5, the spiral groove 30 thereon will rotate. Since the groove wall of the spiral groove 30 is restricted by the two shaft bodies 29, and the two shaft bodies 29 cannot perform circumferential displacement, the transmission shaft 5 will perform axial displacement during the rotation of the transmission shaft 5. Through the axial displacement of the transmission shaft 5, the conveying roller body 2 installed thereon can be axially displaced, thereby completing the deviation correction adjustment of the conveying roller body 2 until the transfer paper is located in the middle area of ​​the conveying roller body 2 again. During the deviation correction adjustment of the conveying roller body 2, since it first moves vertically downward, it has been separated from the transfer paper. Therefore, the self-rotation performed by the mounting frame transmission in this process will not be affected.

[0028] By adopting the above method, first before the deviation correction, the correction roller 3 is deflected, and when it reaches the same horizontal line with the conveying roller body 2, it contacts the transfer paper, and then the conveying roller body 2 moves vertically downward to break away from the contact with the transfer paper. This can utilize the characteristics of the sequence and avoid the defect of causing the transfer paper to move synchronously when the conveying roller body 2 is corrected, thereby causing the position of the transfer paper to be offset.

[0029] At the same time, compared with some traditional methods, in which the transfer paper is directly lifted by moving the correction component, this method does not directly drive the tipping paper to move up and away from the conveying roller body 2. Instead, after taking over the support conditions of the conveying roller body 2, the conveying roller body 2 moves down for correction. This avoids the process of actively lifting the transfer paper. During the correction process, the transfer paper itself is not affected by external forces, thereby further avoiding the displacement of the transfer paper itself.

[0030] Moreover, when the deviation correction operation of the above process is performed, both the deflection of the correction roller 3 and the deviation correction of the conveying roller body 2 are driven by the movement of the driving shaft 6. The maintenance personnel only need to operate at one place during the deviation correction process, which is more convenient to use and has strong practicality. It is worth noting that when the conveying roller body 2 is corrected, its axial displacement utilizes the characteristics of the spiral groove 30. Therefore, during the deviation correction process, although the cross-sectional radius of the spur cylinder 27 is 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, thereby achieving precise control of the movement of the conveying roller body 2, and the maintenance personnel can operate more conveniently and achieve better results when performing deviation correction adjustments.

[0031] Embodiment 3, based on the above embodiment: See also Figures 4 to 8 The locking component includes a pressing rod 31, which is slidably connected to the inner wall of the driving shaft 6. The end of the pressing rod 31 is fixedly connected to a locking spring 32. The end of the locking spring 32 is fixedly connected to the inner wall of the driving shaft 6. An inclined groove 33 is provided on the rod wall of the pressing rod 31. A clamping rod 34 is slidably connected to the shaft wall of the driving shaft 6. A second shaft body 35 is fixedly connected to the surface of the clamping rod 34. The second shaft body 35 is slidably connected to the groove wall of the inclined groove 33.

[0032] In this embodiment, during the second stage of axial displacement of the drive shaft 6 in the above process, that is, when the spur cylinder 27 is driven to mesh with the adjustment gear 26, since the elastic force of the spring 22 is overcome at this time, the maintenance personnel can press the pressing rod 31 to make the pressing rod 31 axially displaced, thereby compressing the locking spring 32, and then through the synchronous displacement of the inclined groove 33, the 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, and after the spur cylinder 27 is meshed with the adjusting gear 26, the maintenance personnel releases the pressing finger, 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 baffle 36 can be passed, so that the drive shaft 6 cannot be axially displaced and reset. In the subsequent correction process, the rotation of the drive shaft 6 will cause the clamping rod 34 to perform circumferential displacement in the cavity, which will not affect the rotation of the drive shaft 6.

[0033] Through the above method, 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 correcting the axial position of the conveying roller body 2, and the practical effect is further improved.

[0034] Working principle: In the production process of cigarette pack transfer paper, a cat's eye laser effect is first molded out in the UV transfer coating process and UV curing is performed, and then a metal aluminum layer is plated on the UV transfer coating layer by vacuum plating to form a cat's eye transfer film layer with an anti-counterfeiting effect, and then it is bonded to the cigarette pack production paper by an adhesive to form a special transfer paper for cigarette packs with a cat's eye pattern anti-counterfeiting mark. The transfer paper is then conveyed by a conveyor device 201 and conveyed into a photolithography machine for positioning photolithography. During the conveying of the transfer paper, since the transfer paper is a low-weight paper, it is easy to cause the conveying roller body 2 to vibrate and deviate due to factors such as tension and vibration. When the conveying roller body 2 vibrates and deviates, it will contact the force sensor 9 on the offset side, so that the force sensor 9 on this side sends a signal to the photoelectric detection board 7. At this time, since the force sensor 9 on the other side has no signal, the photoelectric detection board 7 will display an uneven value state, thereby determining that the conveying roller body 2 is vibrating and deviating. At this time, the conveying of the transfer paper is stopped for adjustment; During adjustment, the maintenance personnel can first move the drive shaft 6 so that the control gear 17 meshes with the teeth of the inner gear ring 16, and then rotate the drive shaft 6 to make the correction roller 3 move in a circular trajectory. When the correction roller 3 moves in a circular trajectory until it contacts the transfer paper and is at the same height as the conveying roller body 2, the drive shaft 6 can be pushed again to make the control gear 17 continue to move axially to lock the position of the correction roller 3. While the locking is completed, the conveying roller body 2 moves vertically downward to break away from the contact with the transfer paper. Then, the drive shaft 6 is rotated again to make the conveying roller body 2 move axially, thereby completing the correction adjustment of the position of the conveying roller body 2 until the transfer paper is located in the middle area of ​​the conveying roller body 2 again, and the positioning and correction work is completed.
