Abstract
Description
Technical Field
[0001] This invention relates to the field of self-adhesive label production and processing equipment, and in particular to a self-adhesive label processing device. Background Technology
[0002] Self-adhesive labels, also known as pressure-sensitive labels, are composite materials made of paper, film, or special materials as the face stock, coated with adhesive on the back, and protected by a silicone-coated backing paper. Their primary purpose is to convey product information to the observer through printed patterns and text on the surface.
[0003] The existing publicly available technology, with publication number CN111495677B, discloses a self-adhesive label manufacturing and processing system, including a base plate, side plates, a support, an unwinding unit, an adhesive coating unit, an adhesive scraping unit, a label pasting unit, and a rewinding unit. This invention can solve the following problems encountered in the current self-adhesive label manufacturing and processing process: a) uneven thickness of the self-adhesive labels during production, resulting in poor adhesion; b) air bubbles easily appearing during pressing in the existing self-adhesive label manufacturing process, leading to inconsistent label sizes; c) slow manufacturing speed, low automation, complex procedures, and high production costs.
[0004] However, the above-mentioned patent still has certain drawbacks in its use: 1. When applying adhesive during the self-adhesive label processing, the use of full-area adhesive coating not only causes adhesive residue in areas where labels are not pasted, affecting the quality of surrounding labels, but also results in excessive adhesive use, leading to uneven label thickness and poor adhesion of the produced labels; 2. The lack of corresponding testing institutions means that some areas may not have the corresponding labels adhered to during the label application process, creating gaps and affecting the quality of subsequent products; 3. The tension of the roll of label tape cannot be adjusted, resulting in loose tape and adhesive buildup on the surface. This not only causes excessive adhesive in some areas, but also makes the folded tape unsuitable for subsequent label adhesion, resulting in less than ideal self-adhesive label production results. Summary of the Invention
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a self-adhesive label processing device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a self-adhesive label processing device, comprising a processing table and a base.

An industrial camera is fixedly installed between the first pressing plate and the lowering plate located on the right side. A drying plate is fixedly installed at one end of the second pressing plate at the top side of the processing channel. A first bearing plate, a docking platform, and a first... are sequentially installed below the coating plate and the drying plate. The system includes a pressure table, a replenishment table, a second pressure table, and a discharge base. A motor is fixedly installed on one side of the top surface of the coating plate.

A second hydraulic rod is fixedly installed on the top surface inside each label tube. A baffle plate is rotatably connected to the bottom surface of each label tube, with a spring connected to one end of the baffle plate. A first pressure block and a second pressure block are respectively installed on the bottom surfaces of the first and second pressure plates. Third hydraulic rods are symmetrically installed on both sides of the bottom surface inside the first bearing plate. A moving plate is fixedly installed on the top surface of the third hydraulic rod. Several sets of label blocks are evenly installed on the top surface of the moving plate. An electrostatic discharger is located on the top surface of the discharge base. A wire is connected to the bottom surface of the electrostatic discharger and is connected to the ground.
[0007] As a further description of the above technical solution:
[0008] The processing table has roller supports symmetrically installed on both sides of the top surface. Feed rollers and take-up rollers are rotatably connected to the bottom of the roller supports. Several sets of first connectors and second connectors are rotatably connected to one end of each feed roller and take-up roller on both sides of the processing table. A fastening knob is connected through the middle of one side surface of each first connector and second connector. Telescopic rods are symmetrically installed on both sides of the bottom of each first connector and second connector. One end of each telescopic rod is connected to a conveying roller. A threaded groove is provided in the middle of the top surface of each conveying roller. An adjusting screw is rotatably connected inside the threaded groove, and one end of the adjusting screw passes through the middle of the bottom surface of each first connector and second connector.
[0009] As a further description of the above technical solution:
[0010] A controller is fixedly installed at the bottom of one side surface of the processing table.
[0011] As a further description of the above technical solution:
[0012] A base is fixedly installed on the bottom surface of the processing table.
[0013] As a further description of the above technical solution:
[0014] A glue tank is fixedly installed on the top surface of the processing channel. One end of the glue tank passes through one side of the processing channel and is connected to the glue nozzle through an infusion pipe.
[0015] As a further description of the above technical solution:
[0016] A felt board is fixedly installed on one side of the bottom of the processing channel, between the first bearing plate and the feed trough.
[0017] As a further description of the above technical solution:

[0019] As a further description of the above technical solution:
[0020] The surface of the conveyor roller is provided with grooves for the movement of the roll label.
[0021] Compared with the prior art, the beneficial effects of the present invention are:
[0022] 1. In this invention, a label block, a coating plate, and a moving plate are used. In actual use, after the roll of self-adhesive label production material moves into the processing channel, it falls onto the surface of the moving plate and abuts against the label block. Then, by raising the moving plate and lowering the coating plate, the label block can move part of the roll of label material to the groove on the surface of the coating plate and bind this part of the roll of label material. At this time, by the back-and-forth movement of the internal scraper and the addition of glue from the glue nozzle, the glue can be evenly applied to the surface of the bound roll of label material, avoiding glue overflow. It can achieve local glue addition, reduce glue waste, and has the advantage of applying glue on demand with less residue.
[0023] 2. This invention employs an industrial camera, a second pressure block, and a lowering plate. The rolled label strip, after being coated with adhesive, moves below the lowering plate. This downward movement allows the label tube to be positioned on the adhesive surface. Then, the internal second hydraulic rod releases the labels one by one, ensuring they accurately land on the adhesive-coated areas. The lowering of the first pressure block firmly presses the labels onto the adhesive surface. The industrial camera then photographs the surface of the rolled label strip, comparing the captured image with a standard image in the terminal to identify unlabeled areas. During subsequent movement of the rolled label strip, the combined use of another lowering plate and the second pressure block allows for secondary label attachment to the damaged areas, improving the overall processing effect, reducing residual defects, and increasing product yield. The labeled rolled label strip then moves below a drying plate, where surface heating elements dry it for a certain period, strengthening the bond between the label and adhesive and preventing detachment due to friction during winding. This improves the overall processing effect and offers advantages such as defect replacement and good processing results. Attached Figure Description

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0036] Example 1, refer to Figure 1-7A self-adhesive label processing device includes a processing table 1 and a base 32. A processing channel 10 is provided at the middle of the bottom surface inside the processing table 1. Feed troughs 9 and discharge troughs 28 are symmetrically arranged at the middle of both ends of the processing channel 10. Several sets of cleaning brushes 8 are evenly installed on the inner surface of the feed troughs 9. Several sets of first hydraulic rods 11 are evenly installed on the top surface inside the processing channel 10 between the feed troughs 9 and the discharge troughs 28. An adhesive application plate 14, a lowering plate 18, a first pressing plate 19, and a second pressing plate 25 are sequentially installed between each pair of first hydraulic rods 11. There are two sets of lowering plates 18, located on the right side of the coating plate 14 and between the right side of the first pressing plate 19 and the second pressing plate 25, respectively. An industrial camera 21 is fixedly installed between the first pressing plate 19 and the lowering plate 18 located on the right side. A drying plate 27 is fixedly installed at one end of the second pressing plate 25, located at the top of the processing channel 10. A first bearing plate 15, a docking platform 40, a first pressing platform 39, a supplementary platform 38, a second pressing platform 36, and a discharge base 35 are installed sequentially below the coating plate 14 and the drying plate 27. The top side of the coating plate 14 has a surface... A motor 45 is fixedly installed on the surface. One end of the motor 45 is connected to several sets of scrapers 43 via a lead screw. A scraper head 42 is installed at an angle on the bottom surface of the scraper 43. An adhesive nozzle 44 is provided in the middle of one side surface of the scraper head 42. Several sets of label tubes 22 are evenly installed on the top surface of the lower plate 18. A second hydraulic rod 23 is fixedly installed on the top surface of the inside of the label tube 22. A baffle plate 24 is rotatably connected to the bottom surface of the label tube 22. A spring 37 is connected to one end of the baffle plate 24. A first clamping plate 19 and a second clamping plate 25 are respectively installed on the bottom surface of the first clamping plate 19 and the second clamping plate 25. The pressure block 20 and the second pressure block 26, the first bearing plate 15, the bottom two sides of the inner surface of the first bearing plate 15 are symmetrically installed with a third hydraulic rod 41, the top surface of the third hydraulic rod 41 is fixedly installed with a movable plate 16, the top surface of the movable plate 16 is evenly installed with a number of label blocks 13, the top surface of the discharge base 35 is provided with an electrostatic discharger 34, the bottom surface of the electrostatic discharger 34 is connected with a wire 33, and the wire 33 is connected to the ground. The electrostatic discharger 34 can remove the static electricity generated during operation, which is convenient for the self-adhesive labels that have been processed.
[0037] Example 2, refer to Figure 1 and Figure 8Inside the processing table 1, roller supports 3 are symmetrically installed on both sides of the top surface. Feeding rollers 2 and receiving rollers 30 are rotatably connected to the bottom of the roller supports 3. Several sets of first connectors 5 and second connectors 29 are rotatably connected to one end of each of the feeding rollers 2 and receiving rollers 30 on both sides of the processing table 1. A fastening knob 4 is threaded through the middle of one side of each of the first connectors 5 and second connectors 29. Telescopic rods 7 are symmetrically installed on both sides of the bottom of the first connectors 5 and second connectors 29. One end of each telescopic rod 7 is connected to a conveyor roller. 48. A threaded groove 47 is provided at the middle position of the top surface of the conveyor roller 48. An adjusting screw 6 is rotatably connected inside the threaded groove 47. One end of the adjusting screw 6 passes through the middle position of the bottom surface of the first connector 5 and the second connector 29. By adjusting the tilt angle of the first connector 5 and the second connector 29 and the distance between them and the conveyor roller 48, the tension of the rolled label tape can be adjusted so that the rolled label tape can be in a relatively taut state, reducing the probability of subsequent folding and ensuring that the glue can be evenly applied to its surface, which is convenient for subsequent label adhesion.
[0038] Example 3, referring to Figure 1 A controller 31 is fixedly installed at the bottom of one side of the processing table 1. The operation of the equipment inside the device can be controlled by the controller 31 and the programming by the personnel.
[0039] Example 4, refer to Figure 1 A base 32 is fixedly installed on the bottom surface of the processing table 1. The device can be fixed by the base 32, which can enhance the overall stability of use.
[0040] Example 5, refer to Figure 1 and Figure 4 A glue tank 12 is fixedly installed on the top surface of the processing channel 10. One end of the glue tank 12 passes through one side of the processing channel 10 and is connected to the glue nozzle 44 through the infusion pipe 17.
[0041] Example 6, refer to Figure 1 and Figure 5 A felt plate 46 is fixedly installed on one side of the bottom of the processing channel 10, between the first bearing plate 15 and the feed trough 9. The felt plate 46 can rub the rolled label tape that is being conveyed in, increasing the overall friction and reducing the possibility of misalignment during conveying. This ensures that the adhesive and label are accurately aligned during the subsequent production of self-adhesive labels, thus improving the actual production effect. On the other hand, the friction of the felt can generate static electricity on the surface of the rolled label tape. The static electricity can attract the rolled label tape to the surface processed by the device, avoiding the possibility of subsequent folding and air bubbles, thus improving the overall use effect.
[0042] Example 7, referring to Figure 1 Both the feeding roller 2 and the take-up roller 30 are connected to a motor at one end. The motor is set to drive both of them to realize the corresponding release and rewind operations, thereby improving the overall operating efficiency of the device.
[0043] Example 8, refer to Figure 1 Figure 8 The surface of the conveyor roller 48 is provided with a groove for the movement of the rolled label tape. The groove is designed to limit the movement trajectory of the rolled label tape, prevent misalignment, and improve the subsequent production effect of self-adhesive labels.
[0044] Working Principle: In actual use, personnel can connect the roll of self-adhesive label production material, adhesive, and labels to the roller bracket 3, adhesive tank 12, and label cylinder 22 respectively for convenient subsequent processing. Then, both ends of the roll of label are respectively fitted onto the surfaces of the feeding roller 2 and the take-up roller 30, and pass through the processing channel 10 to achieve feeding and winding of the roll of label after production, facilitating operation. Next, the roll of label entering the processing channel 10 is first swept by the cleaning brush 8 to remove surface dust, improving surface smoothness. Surface dust adhesion reduces the adhesion of the adhesive. After cleaning, the roll of label moves to the first support plate. At the 15th surface position, the third hydraulic rod 41 lifts the moving plate 16 upwards, allowing the label block 13 on its surface to abut against the surface of the rolled label tape. The lowering of the corresponding first hydraulic rod 11 above it causes a groove on the coating plate 14, slightly larger than the label block 13, to cover it. A portion of the roll of label tape that will be used later is then trapped inside the groove, and this portion of the tape is higher than the rest. The motor 45 on top of the coating plate 14 then drives the scraper 43 to reciprocate within the groove. During this movement, the glue nozzle 44 sprays glue, and the scraper 42 evenly distributes the glue. The adhesive is evenly applied inside the groove, ensuring that the surface of the rolled label tape adheres to the glue. The groove restricts the glue from overflowing, reducing overall glue usage and preventing excess glue from affecting the labels and making them too wet. The glued roll of label tape then moves below the lower plate 18, allowing the label cylinder 22 to be positioned on the glue surface. The second hydraulic rod 23 then releases the labels one by one, ensuring they land precisely on the glued area. The first pressure block 20 then firmly presses the labels onto the glue surface. Finally, the industrial camera 21 captures an image of the rolled label tape's surface. The device compares the captured image with the standard image in the terminal to identify the location where no label is attached. Then, during the subsequent movement of the roll of label tape, the use of another set of lowering plates 18 and the second pressing block 26 allows for the re-attachment of labels to the defective locations, improving the overall processing effect, reducing the amount of residual material, and increasing the product yield. The roll of label tape with the attached label can then be moved to the drying plate 27, where it is dried for a certain period of time using surface heating tubes. This strengthens the bond between the label and the adhesive, preventing the label from falling off due to friction during winding, thus improving the overall processing effect. The device has the advantages of on-demand adhesive application with minimal residue, defect replacement, and good processing results.
