Description

Technical Field

[0001] This utility model relates to the field of paper processing technology, specifically to an anti-counterfeiting paper positioning and conveying mechanism. Background Technology

[0002] Anti-counterfeiting paper is a special type of paper treated with special processes or materials to possess anti-copying and anti-tampering properties. It is commonly used in high-security fields such as banknotes, certificates, tickets, and brand packaging. It achieves authenticity verification through visual, tactile, or instrumental detection methods, effectively curbing counterfeiting. In paper printing equipment, paper conveying devices are often required to continuously transport paper or printed materials forward, enabling the equipment to print accurately.

[0003] A search revealed that application number CN202220303265.9 discloses a paper feeding and positioning conveying device, comprising a frame and a paper conveying platform. The frame is sequentially arranged along the conveying direction of the paper conveying platform, including a paper feeding mechanism, a paper detection mechanism, a paper adsorption and positioning mechanism, and a paper conveying mechanism. These mechanisms are electrically connected. A paper limiting area is provided on the paper conveying platform, and the paper adsorption and positioning mechanism and the paper conveying mechanism are located within this area. This device can convey single sheets of paper through the feeding mechanism, detect the paper's conveying position and direction through the paper detection mechanism, and adsorb and position the paper through the paper adsorption and positioning mechanism. The paper conveying mechanism smoothly and reliably conveys the paper forward, thereby ensuring the accuracy of the printing process.

[0004] However, when the above equipment is in use, after the paper is conveyed by the inclined belt, it first passes through the limiting strip and the limiting groove to adjust the orientation of the paper. However, the corners of the limiting strip and the limiting groove, combined with the continuously rising inclined belt, can easily bend the corners of the paper to force the paper into the limiting groove, thereby affecting the product quality. Utility Model Content

[0005] The purpose of this invention is to provide an anti-counterfeiting paper positioning and conveying mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A counterfeit-proof paper positioning and conveying mechanism, comprising:

[0008] A conveyor frame is provided with a conveyor belt that moves continuously from the conveyor inlet to the conveyor outlet in the middle of the conveyor frame. A positioning part is provided behind the conveyor inlet of the conveyor frame. Adjustment grooves are provided on both sides of the positioning part. The adjustment grooves are connected to the cavity inside the conveyor frame. A first guide rod, a second guide rod and a lead screw are rotatably connected to both sides of the cavity. Positioning components are slidably connected to the first guide rod, the second guide rod and the lead screw.

[0009] Support blocks are provided on both sides of the conveyor frame in front of the conveyor outlet. Dust baffles are fixedly connected between the support blocks, and ion air bars are provided inside the dust baffles.

[0010] Preferably, the positioning component includes a movable plate, which is composed of a long plate and an inclined plate. The long plate has a through hole and a threaded hole, and the inclined plate has a through hole. The through hole is slidably connected to the first guide rod and the second guide rod, respectively, and the threaded hole is threadedly connected to the lead screw.

[0011] Preferably, multiple support columns are fixedly connected to the movable plate, a connecting plate is fixedly connected to the upper end face of the support columns, and multiple driven shafts are rotatably connected to the lower end face of the connecting plate.

[0012] Preferably, a first drive motor is fixedly connected to the upper surface of the connecting plate, the output end of the first drive motor is rotatably connected to the drive shaft, and a transmission belt is rotatably connected to the outer side of the drive shaft and the driven shaft.

[0013] Preferably, the movable plate is positioned within the adjusting groove, and the threads in the threaded holes on the movable plates on both sides of the conveyor frame are opposite.

[0014] Preferably, the ion air bar is fixedly connected to the lower end face of the extension block via a mounting plate, and the extension block is fixedly connected to the lower end face of the dust cover.

[0015] Preferably, the dust shield is rotatably connected to a driven roller on one side of the ion air bar, and the driven roller is provided with multiple positioning wheels.

[0016] Preferably, a flattening roller is rotatably connected to the other side of the ion air bar.

[0017] Preferably, the lead screw is rotatably connected to the output end of the second drive motor on the outside of the conveyor frame, and the second drive motor is fixedly connected to the outside of the conveyor frame through a motor support frame.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This invention features a positioning part on the conveyor frame. The size of the positioning part can be synchronously adjusted by a lead screw to accommodate anti-counterfeiting paper of different sizes. This eliminates the need to produce multiple product models and allows for rapid adjustment based on parameters, thereby improving work efficiency.

[0020] In this invention, a transmission belt is installed on the positioning part. When the paper moves forward at the inlet, the skewed corner of the anti-counterfeiting paper will come into contact with the slanted transmission belt. The transmission belt will correct the paper's orientation and position it along the direction of the moving plate. Since the positioning part can be adjusted to make its width approximately equal to the size of the paper, only the paper that has been aligned and corrected can enter the positioning part and be conveyed backward.

[0021] In this invention, a dust-blocking cover is provided behind the positioning part. Inside the dust-blocking cover, an ionizing air bar and a flattening roller are provided. The ionizing air bar can remove static electricity from the anti-counterfeiting paper, preventing the paper from curling up due to static electricity during subsequent processing, which would affect the quality of the finished product. The flattening roller can evenly flatten the anti-counterfeiting paper without damaging the surface, and its anti-static performance is stable, which facilitates the subsequent processing steps of the paper.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example:

[0031] Please see Figures 1 to 6 This utility model provides a technical solution:

[0032] A counterfeit-proof paper positioning and conveying mechanism, comprising:

[0033] A conveyor frame 1 is provided with a conveyor belt 3 that moves continuously from the conveyor inlet 2 to the conveyor outlet 7 in the middle of the conveyor frame 1. A positioning part 4 is provided behind the conveyor inlet 2 of the conveyor frame 1. Adjustment grooves 401 are provided on both sides of the positioning part 4. The adjustment grooves 401 are connected to the cavity 402 inside the conveyor frame 1. A first guide rod 404, a second guide rod 406 and a lead screw 405 are rotatably connected on both sides of the cavity 402. Positioning components are slidably connected to the first guide rod 404, the second guide rod 406 and the lead screw 405.

[0034] Support blocks 5 are arranged on both sides of the conveyor frame 1 in front of the conveyor outlet 7. Dust baffles 6 are fixedly connected between the support blocks 5. Ionizing air bars 602 are arranged inside the dust baffles 6.

[0035] In this embodiment, the conveyor belt 3 is started, and the second drive motor 411 is started to drive the lead screw 405 to rotate according to the required paper size data. The lead screw 405 is connected to symmetrically arranged movable plates 403 on both sides. The threaded holes 9 on the two movable plates 403 are arranged in opposite directions, so that when the lead screw 405 rotates, it drives the two movable plates 403 to move in opposite directions, so that the movable plates 403 slide in the adjustment groove 401. The shape of the adjustment groove 401 is the same as the shape of the movable plates 403. The lead screw 405 is provided with a first guide rod 404 and a second guide rod 406 on both sides respectively. The first guide rod 404 is located on the long plate side of the movable plate 403, and the second guide rod 406 is located on the inclined plate side of the movable plate 403, so that the movable plates 403 are stable before and after adjustment, and the movable plates 403 are kept parallel. This allows the positioning part 4 to adapt to various anti-counterfeiting paper sizes, eliminating the need to produce multiple models of products, and can be quickly adjusted according to parameters, which is beneficial to improving work efficiency.

[0036] A tapered conveyor inlet 2 is formed between the inclined plate of the moving plate 403 and the conveyor frame 1. The diameter of the conveyor inlet 2 is largest at the inlet and smallest at the positioning part 4. Based on the required paper size data, the spacing between the moving plates 403 is precisely adjusted using the second drive motor 411. The paper is then placed in from one side of the conveyor inlet 2 and moves towards the conveyor outlet 7 under the drive of the conveyor belt 3. The positioning part 4 is located downstream of the conveyor inlet 2. A support column 408 is fixedly connected to the upper end face of the moving plate 403 of the positioning part 4. A connecting plate 407 is fixedly connected to the upper end face of the support column 408. Multiple driven shafts 409 are connected below the connecting plate 407. A first drive motor 410 is also mounted on the connecting plate 407. The first drive motor 410 is rotatably connected to the drive shaft 413 on the lower end face of the connecting plate 407. The drive shaft 413 and the driven shaft 409 are slidably connected to the transmission belt 10. The first drive motor 410 drives the drive shaft 413 to rotate, and the drive shaft 413 drives the transmission belt 10 to rotate, thereby driving the driven shaft 409 to rotate. When the paper at the conveying inlet 2 moves forward, the skewed corner of the anti-counterfeiting paper will come into contact with the slanted transmission belt 10. The transmission belt 10 will slowly correct the paper direction and position it along the direction of the moving plate 403. The correction process will not damage the corner of the paper. Since the positioning part 4 can adjust the width to be approximately equal to the size of the paper, only the corrected paper can enter the positioning part 4 and be conveyed backward.

[0037] Specifically, the positioning component includes a movable plate 403, which consists of a long plate and an inclined plate. The long plate has a through hole 8 and a threaded hole 9, and the inclined plate has a through hole 8. The through hole 8 is slidably connected to the first guide rod 404 and the second guide rod 406, respectively. The threaded hole 9 is threadedly connected to the lead screw 405.

[0038] Specifically, multiple support columns 408 are fixedly connected to the movable plate 403, a connecting plate 407 is fixedly connected to the upper end face of the support column 408, and multiple driven shafts 409 are rotatably connected to the lower end face of the connecting plate 407.

[0039] Specifically, the upper end face of the connecting plate 407 is fixedly connected to the first drive motor 410, the output end of the first drive motor 410 is rotatably connected to the drive shaft 413, and the drive shaft 413 and the driven shaft 409 are rotatably connected to the outside of the drive shaft 413 and the driven shaft 409 by a transmission belt 10.

[0040] Specifically, the movable plate 403 is limited within the adjusting groove 401, and the threads in the threaded holes 9 on the movable plates 403 on both sides of the conveying frame 1 are opposite.

[0041] In this embodiment, a support block 5 is provided behind the positioning part 4, and a dust baffle 6 is provided between the support blocks 5. An ion air bar 602 is provided inside the dust baffle 6. The ion air bar 602 (also known as an electrostatic eliminator) is a device used to eliminate static electricity on the surface of an object. It is widely used in industries such as printing, packaging, plastic processing, and electronics manufacturing. Its core principle is to use the ionization of air to generate positive and negative ions to neutralize the static charge on the surface of the object. The ion air bar 602 can remove static electricity from the anti-counterfeiting paper and prevent the paper from curling up due to static electricity during subsequent processing, which would affect the quality of the finished product.

[0042] In this embodiment, a driven roller 604 is also provided inside the dust cover 6. Multiple positioning wheels 605 are provided on the driven roller 604. After the paper enters the dust cover 6, the positioning wheels 605 press down and position the paper immediately. A drive motor is provided inside the support block 5 and is rotatably connected to the driven roller 604. The rotation speed of the driven roller 604 is the same as the belt speed of the conveyor belt 3. While the anti-counterfeiting paper is moving forward, it presses down the paper to prevent the ion air bar 602 from moving the paper position.

[0043] In this embodiment, a flattening roller 606 is also provided inside the dust shield 6. After the paper passes through the ion air bar 602 to remove static electricity, it leaves the dust shield 6 through the flattening roller 606 and enters the subsequent equipment through the conveying outlet 7. A drive motor is provided inside the support block 5 and is rotatably connected to the flattening roller 606. The rotation speed of the flattening roller 606 is the same as the belt speed of the conveyor belt 3. The flattening roller 606 is made of antistatic rubber (such as nitrile rubber), which has moderate elasticity and can evenly flatten the anti-counterfeiting paper without damaging the surface. In addition, the antistatic performance is stable, which facilitates the subsequent processing steps of the paper.

[0044] Specifically, the ion wind bar 602 is fixedly connected to the lower end face of the extension block 601 via the mounting plate 603, and the extension block 601 is fixedly connected to the lower end face of the dust cover 6.

[0045] Specifically, the dust shield 6 is rotatably connected to a driven roller 604 on one side of the ion air bar 602, and the driven roller 604 is provided with a plurality of positioning wheels 605.

[0046] Specifically, a flattening roller 606 is rotatably connected to the other side of the ion air bar 602.

[0047] Specifically, the lead screw 405 is rotatably connected to the output end of the second drive motor 411 on the outside of the conveyor frame 1, and the second drive motor 411 is fixedly connected to the outside of the conveyor frame 1 through the motor support frame 412.

[0048] In use, the conveyor belt 3 is started to transport the paper according to the required size data. The second drive motor 411 is then started, which drives the lead screw 405 to rotate. The lead screw 405 is connected to symmetrically arranged movable plates 403 on both sides. The threaded holes 9 on the two movable plates 403 are arranged in opposite directions, so that when the lead screw 405 rotates, it drives the two movable plates 403 to move in opposite directions, causing the movable plates 403 to slide in the adjustment groove 401. The shape of the adjustment groove 401 is the same as the shape of the movable plates 403. The lead screw 405 is provided with a first guide rod 404 and a second guide rod 406 on both sides. The first guide rod 404 is located on the long plate side of the movable plate 403, and the second guide rod 406 is located on the inclined plate side of the movable plate 403. This ensures that the movable plates 403 are stable before and after adjustment and keeps the movable plates 403 parallel. The positioning part 4 can adapt to various anti-counterfeiting paper sizes, eliminating the need to produce multiple models of products. It can also be quickly adjusted according to parameters, which helps to improve work efficiency.

[0049] A tapered conveyor inlet 2 is formed between the inclined plate of the moving plate 403 and the conveyor frame 1. The diameter of the conveyor inlet 2 is largest at the inlet and smallest at the positioning part 4. Based on the required paper size data, the spacing between the moving plates 403 is precisely adjusted using the second drive motor 411, and the paper is put in from one side of the conveyor inlet 2. The paper moves towards the conveyor outlet 7 under the drive of the conveyor belt 3. Since the positioning part 4 is set in the subsequent direction of the conveyor inlet 2, the upper end face of the moving plate 403 of the positioning part 4 is fixedly connected to the support column 408. The upper end face of the support column 408 is fixedly connected to the connecting plate 407. Multiple driven shafts 409 are connected below the connecting plate 407. At the same time, the first drive motor 410 is set on the connecting plate 407. 10 is rotatably connected to the drive shaft 413 on the lower end face of the connecting plate 407. The drive shaft 413 and the driven shaft 409 are slidably connected to the transmission belt 10. The first drive motor 410 drives the drive shaft 413 to rotate, and the drive shaft 413 drives the transmission belt 10 to rotate, thereby driving the driven shaft 409 to rotate. When the paper at the conveying inlet 2 moves forward, the skewed corner of the anti-counterfeiting paper will contact the slanted transmission belt 10. The transmission belt 10 will correct the paper direction and position it along the direction of the moving plate 403. Since the positioning part 4 can adjust the width so that the width is approximately equal to the size of the paper, only the aligned and corrected paper can enter the positioning part 4 and be conveyed backward. After passing through the dust cover 6 to remove static electricity and flatten it, it enters the subsequent equipment for processing through the conveying outlet 7.

[0050] All other parts of this utility model not described herein are the same as existing technologies, or are known technologies, or can be implemented using existing technologies, and will not be described in detail here.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
