Abstract
Description
Technical Field
[0001] This utility model relates to the field of anti-counterfeiting label production and processing technology, specifically to an automatic feeding and positioning device for anti-counterfeiting label materials. Background Technology
[0002] In the large-scale production of anti-counterfeiting labels, the processing from roll substrate to finished label involves multiple continuous processes such as unwinding, conveying, printing, die-cutting, and cutting. Among these, stable conveying and precise positioning of the substrate are key prerequisites for ensuring the accuracy of subsequent processing and reducing the defect rate.
[0003] Existing feeding devices mostly use fixed-width guide structures, which can only accommodate a single specification of anti-counterfeiting label material. With the diversification of anti-counterfeiting label applications and the increasing differences in label sizes, when it is necessary to change to a different width of substrate, the entire guide assembly must be disassembled and replaced. This operation is cumbersome and time-consuming, not only reducing production efficiency but also increasing equipment debugging costs. Furthermore, the device has extremely poor versatility. Moreover, the connection stability between the unwinding and conveying stages is unsatisfactory. In most devices, the unwinding mechanism and the feeding plate are discontinuous, with a transition gap. After the rolled substrate is released from the winding shaft, it must pass through a non-smooth transition before entering the feeding plate, easily causing wrinkles and tensile deformation due to uneven stress.
[0004] In view of this, we propose an automatic feeding and positioning device for anti-counterfeiting label materials. Utility Model Content
[0005] To overcome the above deficiencies, this utility model provides an automatic feeding and positioning device for anti-counterfeiting label materials.
[0006] The technical solution of this utility model is:
[0007] An automatic feeding and positioning device for anti-counterfeiting label materials includes a horizontally positioned feeding plate with two symmetrically arranged guide plates. Both guide plates are inclined and gradually taper from right to left. An adjustment mechanism for adjusting the distance between the two guide plates is installed at the bottom of the feeding plate. A base is located on the right side of the feeding plate, and two vertical plates are symmetrically fixedly mounted on the top of the base. A second connecting block is rotatably mounted on each vertical plate. A winding shaft is located between the two second connecting blocks, and a first connecting block is integrally formed on both ends of the winding shaft. The first connecting block and the adjacent second connecting block are fixed by several bolts. An unwinding motor with an output shaft coaxially fixed to the second connecting block is installed on one of the vertical plates. By setting the inclined and gradually tapering guide plates, the anti-counterfeiting label material can be automatically guided, ensuring that the material gradually returns to its correct position during transportation and reducing deviation. The adjustment mechanism can flexibly adjust the distance between the two guide plates to adapt to materials of different widths, enhancing the device's versatility. The unwinding motor drives the winding shaft to achieve automatic unwinding. Combined with the detachable winding shaft design, it is convenient to change different rolls of material, thus improving the overall automation and adaptability of the feeding and positioning.
[0008] As a preferred technical solution, the feeding plate is fixedly connected to the left outer wall of both vertical plates. The fixed connection between the feeding plate and the vertical plates improves the overall structural stability of the device. The top of the winding shaft is flush with the bottom of the feeding plate, ensuring that the material transitions smoothly from the winding shaft to the feeding plate without any drop, reducing wrinkles or deviations caused by height differences in the material, and improving the stability of the conveying.
[0009] As a preferred technical solution, a diagonal brace is fixedly installed near the right side of the bottom of the feeding plate, and the diagonal brace is fixedly connected to both vertical plates. This further strengthens the structural strength of the connection between the feeding plate and the vertical plates and distributes the pressure on the feeding plate.
[0010] As a preferred technical solution, two vertically arranged first guide shafts are rotatably installed between the two vertical plates. The first guide shafts are located near the feeding plate, and the gap between the two first guide shafts is flush with the top of the feeding plate. The arrangement of the two first guide shafts plays a role in pre-guiding and initial compaction of the material about to enter the feeding plate.
[0011] As a preferred technical solution, a second guide shaft is rotatably mounted inside the feeding plate near the left side. The second guide shaft passes through two guide plates, both of which have through holes for the second guide shaft to pass through. The second guide shaft further limits and guides the material after it has passed through the guide plates, ensuring that the material maintains a precise position when it is output from the left side of the feeding plate.
[0012] As a preferred technical solution, the adjusting mechanism includes threaded rods fixedly connected to two guide plates respectively. One end of the threaded rod, away from the guide plate, extends to the outside of the feeding plate. A second spur gear, threadedly connected to the threaded rod, is rotatably mounted on the outer wall of the feeding plate. The threaded rod is not connected to the feeding plate. By rotating the second spur gear, the movement distance of the guide plates can be precisely controlled, enabling fine-tuning of the distance between the two guide plates and ensuring accurate adaptation of the guide plates to materials of different widths.
[0013] As a preferred technical solution, the adjustment mechanism further includes a fixing rod fixed to the bottom of the feeding plate. A drive rod is rotatably installed inside the fixing rod. A first spur gear is coaxially fixed to the outer circumference of the drive rod below each second spur gear. The first spur gear meshes with the second spur gear. An adjustment knob is integrally formed on one end of the drive rod. Through the meshing of the first and second spur gears, the drive rod can synchronously drive the two second spur gears to rotate, achieving synchronous adjustment of the two guide plates. This ensures that the two guide plates are always symmetrically distributed after adjustment, avoiding positioning deviations caused by unilateral adjustment.
[0014] As a preferred technical solution, a fixing hole is provided at each of the four corners of the base. The fixing holes at the four corners of the base facilitate the secure installation of the device on the workbench using bolts or other connecting components.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] This invention features an inclined, gradually tapering guide plate that automatically guides the anti-counterfeiting label material, ensuring it gradually corrects itself during transport and reducing deviation. An adjustment mechanism allows for flexible adjustment of the distance between the two guide plates to accommodate materials of varying widths, enhancing the device's versatility. An unwinding motor drives the winding shaft for automatic unwinding, and the detachable winding shaft design facilitates the replacement of different rolls, thus improving the overall automation and adaptability of the feeding and positioning process.

[0024] Please see Figures 1-4 This utility model provides a technical solution:
[0025] An automatic feeding and positioning device for anti-counterfeiting label materials includes a horizontally arranged feeding plate 1, on which two guide plates 10 are symmetrically arranged. Both guide plates 10 are inclined and gradually narrow from right to left. An adjustment mechanism 4 for adjusting the distance between the two guide plates 10 is installed at the bottom of the feeding plate 1. A base 3 is provided on the right side of the feeding plate 1. Two vertical plates 2 are symmetrically fixedly installed on the top of the base 3. A second connecting block 20 is rotatably installed on each vertical plate 2. A winding shaft 6 is provided between the two second connecting blocks 20. A first connecting block 60 is integrally formed on both ends of the winding shaft 6. The first connecting block 60 and the adjacent second connecting block 20 are fixed by several bolts. An unwinding motor 21 with an output shaft coaxially fixed to the second connecting block 20 is installed on one of the vertical plates 2. By setting an inclined and gradually narrowing guide plate 10, the anti-counterfeiting label material can be automatically guided, ensuring that the material gradually returns to its correct position during the conveying process and reducing deviation; the adjustment mechanism 4 can flexibly adjust the distance between the two guide plates 10 to adapt to materials of different widths and enhance the versatility of the device; the unwinding motor 21 drives the winding shaft 6 to achieve automatic unwinding, and the design of the detachable winding shaft 6 makes it easy to change different rolls, thus improving the automation and adaptability of the feeding and positioning.
[0026] As a preferred embodiment, the feeding plate 1 is fixedly connected to the left outer wall of both vertical plates 2. The fixed connection between the feeding plate 1 and the vertical plates 2 improves the overall structural stability of the device. The top of the winding shaft 6 is flush with the bottom of the feeding plate 1, ensuring that the material transitions smoothly from the winding shaft 6 to the feeding plate 1 without any drop, reducing the wrinkles or deviations of the material caused by the height difference, and improving the smoothness of the conveying.
[0027] In a preferred embodiment, a diagonal brace 5 is fixedly installed near the right side of the bottom of the feeding plate 1, and the diagonal brace 5 is fixedly connected to both vertical plates 2. This further strengthens the structural strength of the connection between the feeding plate 1 and the vertical plates 2 and disperses the pressure on the feeding plate 1.
[0028] In a preferred embodiment, two vertically arranged first guide shafts 22 are rotatably mounted between the two vertical plates 2. The first guide shafts 22 are located near the feeding plate 1, and the gap between the two first guide shafts 22 is flush with the top of the feeding plate 1. The arrangement of the two first guide shafts 22 plays a role in pre-guiding and initial compaction of the material about to enter the feeding plate 1.
[0029] In a preferred embodiment, a second guide shaft 11 is rotatably mounted inside the feeding plate 1 near the left side. The second guide shaft 11 passes through two guide plates 10, and each of the two guide plates 10 has a through hole 100 for the second guide shaft 11 to pass through. The second guide shaft 11 provides a second limiting and guiding function for the material after it has passed through the guide plates 10, ensuring that the material maintains a precise position when it is output from the left side of the feeding plate 1.
[0030] In a preferred embodiment, the adjusting mechanism 4 includes threaded rods 43 fixedly connected to the two guide plates 10 respectively. One end of the threaded rod 43, away from the guide plate 10, extends to the outside of the feeding plate 1. A second spur gear 42, threadedly connected to the threaded rod 43, is rotatably mounted on the outer wall of the feeding plate 1. The threaded rod 43 is not connected to the feeding plate 1. By rotating the second spur gear 42, the moving distance of the guide plates 10 can be precisely controlled, enabling fine-tuning of the distance between the two guide plates 10 and ensuring accurate adaptation of the guide plates 10 to materials of different widths.
[0031] In a preferred embodiment, the adjustment mechanism 4 further includes a fixing rod 40 fixed to the bottom of the feeding plate 1. A drive rod 45 is rotatably mounted inside the fixing rod 40. A first spur gear 41 is coaxially fixed to the outer circumference of the drive rod 45 below each second spur gear 42. The first spur gear 41 meshes with the second spur gear 42. An adjustment knob 44 is integrally formed on one end of the drive rod 45. Through the meshing of the first spur gear 41 and the second spur gear 42, the drive rod 45 can synchronously drive the two second spur gears 42 to rotate, realizing the synchronous adjustment of the two guide plates 10. This ensures that the two guide plates 10 are always symmetrically distributed after adjustment, avoiding positioning deviation caused by unilateral adjustment.
[0032] As a preferred embodiment, the base 3 has a fixing hole near each of its four corners. The fixing holes at the four corners of the base 3 facilitate the secure mounting of the device on the workbench using bolts or other connecting components.
[0033] In use, the automatic feeding and positioning device for anti-counterfeiting label materials of this utility model is first securely installed on the workbench through the fixing holes at the four corners of the base 3 to ensure stable overall operation. The roll of anti-counterfeiting label material is then installed on the winding shaft 6. The first connecting blocks 60 at both ends of the winding shaft 6 are fixed to the second connecting blocks 20 on the vertical plate 2 using bolts, completing the roll loading. The unwinding motor 21 is then started, and its output shaft drives the second connecting blocks 20 and the winding shaft 6 to rotate, achieving automatic unwinding of the material.
[0034] After unwinding, the material first passes through two vertically positioned first guide shafts 22. The gap between the two shafts is flush with the top of the feeding plate 1, which serves to pre-guide and initially compress the material, ensuring that it enters the feeding plate 1 smoothly in a horizontal state. After entering the feeding plate 1, the material is conveyed between two inclined and gradually narrowing guide plates 10. The guide plates 10 automatically guide the material through their gradually contracting structure, gradually correcting the material's orientation during conveying and reducing deviation.
[0035] When different widths of materials need to be accommodated, rotating the adjustment knob 44 drives the drive rod 45 to rotate. The first spur gear 41 on the drive rod 45 synchronously drives the second spur gears 42 on both sides to rotate. Through the threaded engagement of the second spur gears 42 and the threaded rod 43, the two guide plates 10 move synchronously in opposite directions, precisely adjusting the spacing and always maintaining a symmetrical distribution. After being guided by the guide plates 10, the material passes through the second guide shaft 11 on the left side of the feed plate 1. The second guide shaft 11 again limits and guides the material, ensuring that the material is output from the feed plate 1 in a precise position, providing a stable positioning reference for subsequent processing steps.
