Description

Technical Field

[0001] This application relates to the technical field of labels, and in particular to an anti-counterfeiting and anti-theft label and its adhesive coating equipment. Background Technology

[0002] Anti-counterfeiting and anti-theft labels refer to cards or papers printed with anti-counterfeiting features. Attached to the object, these labels can be understood as the object's identification card, thereby reducing market disruptions caused by counterfeiting, imitation, and theft.

[0003] Common labels mainly consist of a printed layer, a paper base, and a cover layer. The printed layer is located on one side of the paper base and is formed after anti-counterfeiting information is printed. The cover layer is a coating layer, generally formed by spraying paint, and its material is usually scratch-off silver. Label production is carried out using a label printing machine. For example, Chinese utility model patent CN217532230U discloses an anti-counterfeiting label printing device, which mainly includes a support base, a feeding roller, a rewind roller, and a printer. The feeding roller, rewind roller, and printer are all mounted on the base. The feeding roller and rewind roller are located on opposite sides of the printer. One end of the label paper is wound around the feeding roller, and the other end is wound around the rewind roller, with the label paper passing through the printer. During the printing process, the feeding roller rotates to feed the label, while the printer prints anti-counterfeiting information on the label paper. Then, the rewind roller rewinds the label, and finally, the scratch-off silver is printed.

[0004] Scratch-off silver is used to cover anti-counterfeiting information to reduce the possibility of this information being leaked. When consumers verify product information, they need to scratch off the scratch-off silver layer to reveal the anti-counterfeiting information. Consumers usually need a tool similar to a scraper to remove the scratch-off silver. However, consumers cannot carry such tools, so they often use their fingernails to scratch it off. Because fingernails are not smooth, multiple scratches are required to fully reveal the anti-counterfeiting information, causing inconvenience for consumers verifying product authenticity. Furthermore, the scratch-off silver material can easily become embedded in the fingernails, posing a risk of ingestion. Summary of the Invention

[0005] To facilitate consumers in verifying product information, this application provides an anti-counterfeiting and anti-theft label and its adhesive application equipment.

[0006] The anti-counterfeiting and anti-theft label and its adhesive coating equipment provided in this application adopt the following technical solution:

[0007] An anti-counterfeiting and anti-theft label includes a base layer and a protective layer. A first adhesive layer is disposed between the protective layer and the base layer. The first adhesive layer includes a horizontal part and two vertical parts. The two vertical parts are spaced apart along a direction parallel to the base layer. The horizontal part is located between the two vertical parts. The protective layer is connected to the base layer through the first adhesive layer. Anti-counterfeiting information is printed on the side of the base layer near the protective layer.

[0008] By adopting the above technical solution, the two vertical parts and one horizontal part of the first adhesive layer are connected to form a U-shape. After the protective layer is connected to the base layer through the first adhesive layer, a shell with an opening on one side is formed. Workers can quickly peel off the protective layer from the side away from the horizontal part, facilitating verification of the product based on the anti-counterfeiting information on the base layer. Compared with traditional scratch-off silver covering of anti-counterfeiting information, this method firstly avoids the tedious step of workers repeatedly scratching, and secondly reduces the possibility of scratch-off silver embedding in fingernails and causing accidental ingestion by consumers, thus improving the security of anti-counterfeiting and anti-theft labels during use.

[0009] Optionally, a second adhesive layer is provided on the side of the base layer away from the protective layer, and the structural strength of the base layer is less than the adhesive capacity of the second adhesive layer.

[0010] By adopting the above technical solution, the second adhesive layer facilitates the application of labels to products by staff. Since the strength of the base layer structure is less than the adhesive capacity of the second adhesive layer, removing the label after application requires damaging the base layer. This reduces the likelihood of the label being removed entirely for theft, thus improving the overall anti-counterfeiting and anti-theft effectiveness of the label.

[0011] Optionally, an easy-tear opening is provided on the protective layer at a position away from the horizontal part, and a pull part is connected to the easy-tear opening.

[0012] By adopting the above technical solution, when the pull part is pulled, the stress is concentrated at the position where the pull part connects to the protective layer on both sides under the action of the easy-tear opening, which makes it easier for staff to tear open the protective layer and further facilitates consumers to observe the anti-counterfeiting information.

[0013] An anti-counterfeiting and anti-theft label coating device includes a support frame and a feeding roller mounted on the support frame, and a coating device. The coating device includes a glue dispensing mechanism and two rotating disks. The two rotating disks are arranged in parallel and spaced apart, and the rotating disks are rotatably mounted on the support frame. The glue dispensing mechanism includes multiple sets of glue dispensing components, which are evenly arranged on the rotating disks around the rotation axis of the rotating disks. The rotation of the rotating disks can drive the multiple sets of glue dispensing components to sequentially circulate and contact the base paper. The contact between the glue dispensing components and the base paper enables the application of glue liquid to the base paper.

[0014] By adopting the above technical solution, during the production process, the base paper is wound on the feeding roller. As the feeding roller rotates, the end of the base paper away from the feeding roller moves horizontally and passes through the gluing device. At the same time, the rotating disk rotates, and as the rotating disk rotates, multiple sets of glue dispensing components come into contact with the base paper in sequence and apply glue to the base paper to form the first adhesive layer, thus completing the gluing process of the base paper.

[0015] Optionally, the dispensing assembly includes a slide plate and multiple dispensing blocks. The slide plate is an arc-shaped plate, and its two sides perpendicular to its own axis are respectively connected to two rotating disks. The dispensing blocks are mounted on the slide plate, and the dispensing blocks of the multiple dispensing assemblies are arranged in a shape corresponding to the first adhesive layer. The dispensing blocks are hollow inside, forming a storage cavity for storing adhesive. The side of the dispensing block away from the rotation axis of the rotating disk is provided with a dispensing port, and the adhesive in the storage cavity can overflow from the dispensing port.

[0016] By adopting the above technical solution, when the gluing device is working, the glue inside the glue dispensing block overflows from the glue outlet plate. As the rotating plate rotates, the glue dispensing block comes into contact with the base paper and prints the glue from the glue outlet on the base paper, thus achieving glue coating on the base paper.

[0017] Optionally, the dispensing block has a ring structure and is slidably mounted on the slide plate in a direction parallel to the axis of the rotating disk.

[0018] By adopting the above-mentioned technical features, the sliding dispensing block can change the position of the dispensing block, thereby changing the shape of the dispensing blocks composed of multiple dispensing components and improving the applicability of the coating equipment.

[0019] Optionally, the slide plate is provided with a locking assembly, which includes a retaining plate. A groove is provided on the side of the slide plate in a direction parallel to its own axis. The retaining plate is slidably connected to the side wall of the groove. Sliding the retaining plate can make the retaining plate press against the inner side wall of the rubber block.

[0020] By adopting the above technical solution, the sliding clamping plate is pressed against the inner wall of the glue dispensing block. Under the action of friction, the clamping plate can limit the sliding of the glue dispensing block, thereby improving the stability of the glue dispensing block during the glue application process.

[0021] Optionally, the locking assembly further includes a pull plate and a push rod. The slide plate has a groove on its side perpendicular to its own axis. The pull plate is slidably connected in the groove. One end of the push rod is connected to the abutment plate, and the other end extends towards the pull plate. The pull plate has a drive groove, which includes a drive ramp. Moving the pull plate away from the slide plate can drive the push rod to move away from the pull plate.

[0022] By adopting the above technical solution, pulling the pull plate causes the push rod to move under the action of the driving inclined plane. This, in turn, moves the abutment plate connected to the push plate, thereby limiting the position of the dispensing block. The pull plate design allows the operator to lock the dispensing block simply by pulling it from one side of the slide plate, making it convenient for operators to limit the dispensing block's position.

[0023] Optionally, the rotating disk is provided with a linkage component, which includes a lever. One end of the pull plate extends through the rotating disk to the side of the rotating disk away from the slide plate. The lever is rotatably connected to the rotating disk. The pull plate has a rotation groove. One end of the lever is inserted into the rotation groove. Rotating the lever can drive the pull plate to move.

[0024] By adopting the above technical solution, applying force to the end of the lever away from the pull plate can cause the lever to rotate. During the rotation of the lever, the end of the lever inserted into the pull plate moves closer to or further away from the rotating disk, thereby driving the pull plate to move and realizing the adjustment of the position of the pull plate.

[0025] Optionally, the linkage assembly further includes a linkage ring and a mounting ring. The mounting ring is a circular ring structure and is located on the side of the rotating disk away from the slide plate. The mounting ring is coaxial with the rotation axis of the rotating disk. The linkage ring is a circular ring structure and is coaxially mounted on the mounting ring and threadedly connected to the mounting ring. An annular groove is provided on the outer wall of the linkage ring, and the ends of the multiple levers away from the pull plate are all inserted into the annular groove.

[0026] By adopting the above technical solution, the linkage ring is threaded onto the mounting ring. Rotating the linkage ring allows it to move closer to or further away from the rotating disk due to the threaded action. As the linkage ring moves, the lever slides relative to it within the annular groove. With the movement of the linkage ring, the lever rotates, causing the ends of multiple levers near the pull plates to simultaneously move closer to or further away from the rotating disk, thus achieving simultaneous control of the positions of multiple pull plates.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. Applying a force away from the substrate to the pull section, the stress concentrates on both sides of the pull section where it contacts the protective layer, causing the protective layer to break. After the protective layer breaks, the anti-counterfeiting information on the substrate is exposed, making it easier for staff to verify the product.

[0029] 2. Multiple adhesive dispensing blocks form a shape corresponding to the first adhesive layer. As the rotating disk drives the adhesive dispensing blocks to contact the base paper one by one, the dispensing blocks apply adhesive to the base paper and form the first adhesive layer, completing the adhesive coating process of the base paper.

[0041] The following is in conjunction with the appendix Figure 1-10This application will be described in further detail.

[0042] This application discloses an anti-counterfeiting and anti-theft label.

[0043] Reference Figure 1 An anti-counterfeiting and anti-theft label includes a base layer 1 and a protective layer 11, which are bonded together. A first adhesive layer 12 is provided between the base layer 1 and the protective layer 11, and the protective layer 11 is connected to the base layer 1 through the first adhesive layer 12. Anti-counterfeiting and anti-theft information is printed on the side of the base layer 1 closest to the protective layer 11 for verifying product information. A second adhesive layer 13 is provided on the side of the base layer 1 furthest from the protective layer 11, and the second adhesive layer 13 is used to connect the base layer 1 to the product.

[0044] Reference Figure 1 The first adhesive layer 12 includes a horizontal portion 121 and two vertical portions 122. Both the horizontal portion 121 and the vertical portions 122 are elongated structures, with the two vertical portions 122 located at both ends of the horizontal portion 121. The two ends of the horizontal portion 121 are connected to the two vertical portions 122, forming a U-shape. The edge of the protective layer 11 is bonded to the base layer 1 via the first adhesive layer 12. Consumers can tear open the protective layer 11 from the side not bonded to the base layer 1 to reveal anti-counterfeiting information.

[0045] Reference Figure 1 To further facilitate consumers in peeling off the protective layer 11, an easy-tear opening 112 is provided on the protective layer 11. The easy-tear opening 112 is located away from the horizontal portion 121. A pull part 111 is provided at the easy-tear opening 112, with one side of the pull part 111 connected to the edge of the easy-tear opening 112 near the horizontal portion 121. In this embodiment, a cut is made in the protective layer 11 away from the horizontal portion 121 to form a cutting line, and two parallel cutting lines are provided along the length direction of the horizontal portion 121 to form the pull part 111. After the pull part 111 is bent, the easy-tear opening 112 is formed on the protective layer 11. During the label anti-counterfeiting information verification process, the pull part 111 is pulled away from the protective layer 11 in a direction perpendicular to the protective layer 11. The stress is concentrated on both sides of the pull part 111 through the easy-tear opening 112, thereby facilitating consumers to peel off the protective layer 11 to verify the product information.

[0046] Reference Figure 2 The tensile strength of the base layer 1 is less than the adhesive strength of the second adhesive layer 13. When the anti-counterfeiting and anti-theft label is affixed to the product and you want to remove it, the base layer 1 breaks during the removal process because the tensile strength of the base layer 1 is less than the adhesive strength of the second adhesive layer 13. This reduces the possibility of the anti-counterfeiting and anti-theft label being removed as a whole and used on counterfeit or substandard products, thus improving the anti-theft and anti-counterfeiting effect of the label.

[0047] This application also discloses an anti-counterfeiting and anti-theft label coating device.

[0048] The adhesive applicator in this embodiment is used to apply adhesive to the base layer 1 of the anti-counterfeiting and anti-theft label provided in this application, thereby forming the first adhesive layer 12.

[0049] Reference Figure 2 An anti-counterfeiting and anti-theft label coating device includes a support 2, a feeding roller 21, and a coating device 3. The feeding roller 21 and the coating device 3 are both mounted on the support 2 (here, the raw materials refer to the base layer 1 and the protective layer 11). The feeding roller 21 has a cylindrical structure. The axis of the feeding roller 21 is parallel to the ground, and the feeding roller 21 is rotatably connected to the support 2 around its own axis. The base layer 1 (in the mass production of labels, the raw material of the base layer 1 is roll material, which is subsequently cut into individual labels; for ease of description, the raw material of the base layer 1 is defined as base paper) is wound around the feeding roller 21 at one end, and the other end extends horizontally towards the coating device 3. The end of the base paper away from the feeding roller 21 passes through the coating device 3 and is connected to the take-up roller (not shown in the figure) for the subsequent process. The take-up roller provides a pulling force to the base layer 1 in a direction away from the feeding roller 21, thereby moving the base layer 1. Then, through repeated glue application by the glue application device 3, multiple first adhesive layers 12 are continuously formed on the base layer 1, realizing continuous production of labels.

[0050] Reference Figure 1 and Figure 2 The gluing device 3 includes a rotating disk 31 and a glue dispensing mechanism 32. Two rotating disks 31 are arranged at intervals on the support 2 along a direction parallel to the axis of the feeding roller 21. Each rotating disk 31 has a disc-shaped structure and can rotate around its own axis. The glue dispensing mechanism 32 is installed between the two rotating disks 31, and its rotation drives the rotation of the rotating disks 31. The base paper is located below the rotating disks 31, and moves horizontally during the gluing process. Simultaneously, the rotating disks 31 rotate in coordination with the movement of the base paper. During this rotation, the rotating disks 31 drive the glue dispensing mechanism 32 to circulate and contact the base paper, uniformly coating different positions on the base paper to achieve continuous gluing.

[0051] Reference Figure 2 and Figure 3 The glue dispensing mechanism 32 includes multiple sets of glue dispensing components 4, which are evenly arranged on the rotating disk 31 around its rotation axis. The multiple sets of glue dispensing components 4 cooperate with each other, and when they come into contact with the base layer 1, they form a specific shape on the base paper, namely the U-shaped structure of the first adhesive layer 12.

[0052] Reference Figure 2 , Figure 3 and Figure 4The adhesive dispensing assembly 4 includes a slide plate 41 and multiple dispensing blocks 42. The slide plate 41 has an arc-shaped plate structure and is coaxially arranged with the rotating disk 31. The two sides of the slide plate 41 perpendicular to its own axis are welded to the two sides of the rotating disk 31 that are close to each other. The dispensing blocks 42 are annular, and multiple dispensing blocks 42 are slidably fitted onto the slide plate 41 in a direction parallel to the axis of the slide plate 41. The dispensing blocks 42 are hollow inside, forming a storage cavity for storing adhesive. Multiple dispensing ports are evenly arranged on the side of the dispensing block 42 away from its own axis, and the adhesive in the storage cavity can overflow from the dispensing ports. By sliding the dispensing blocks 42 in different sets of adhesive dispensing assemblies 4, multiple sets of dispensing blocks 42 in multiple sets of adhesive dispensing assemblies 4 can be arranged into different shapes. When the dispensing blocks 42 of multiple sets of adhesive dispensing assemblies 4 come into contact with the base paper, a specific shape can be formed on the base paper. In this embodiment, the dispensing blocks 42 of different sets of adhesive dispensing assemblies 4 are combined to form a shape corresponding to the first adhesive layer 12.

[0053] Reference Figure 2 , Figure 3 and Figure 4 The glue dispensing block 42 is arc-shaped, and its inner sidewall is in contact with the sidewall of the slide plate 41. During the rotation of the rotating disk 31, the side of the glue dispensing block 42 with the glue outlet rolls on the original paper, thereby applying the glue to the original paper and improving the uniformity of the glue application by the glue application device 3.

[0054] Reference Figure 2 , Figure 3 and Figure 4 A glue supply device 5 for supplying glue to the glue dispensing block 42 is provided between the two rotating disks 31. The glue supply device 5 includes a glue supply main pipe 51, a flexible glue tube 52, and a connector 53. The glue supply main pipe 51 is a round pipe and is coaxially arranged with the rotating disk 31. Two support plates are spaced apart on the bracket 2 along a direction parallel to the rotation direction of the rotating disk 31. One end of the glue supply main pipe 51 is welded to one of the support plates, and the other end extends horizontally towards the other support plate and passes through the other support plate to connect with the glue supply device (not shown in the figure). The rotating disk 31 is coaxial with the glue supply main pipe 51. A clearance hole is opened on the rotating disk 31 corresponding to the position of the glue supply main pipe 51. The rotating disk 31 is rotatably sleeved on the glue supply main pipe 51 to realize the rotatable connection between the rotating disk 31 and the glue supply main pipe 51. Multiple flexible hoses 52 are provided corresponding to the dispensing blocks 42. One end of each flexible hose 52 is connected to the storage cavity of the dispensing block 42, and the other end is connected to the inside of the glue supply main pipe 51 through a connector 53. The glue supply device delivers glue into the glue supply main pipe 51, and the glue enters each flexible hose 52 along the glue supply main pipe 51, thereby realizing the glue supply to the dispensing blocks.

[0055] Reference Figure 2 , Figure 3 and Figure 4A solenoid valve (not shown in the figure) is installed on the flexible adhesive tube 52, and the solenoid valve is controlled by a PLC program. When the adhesive applicator 3 is in use, the PLC program controls the dispensing of adhesive from specific dispensing blocks 42 (i.e., dispensing blocks 42 that form a specific shape) to reduce adhesive waste.

[0056] Reference Figure 2 , Figure 3 and Figure 4 A through hole is provided on the side wall of the glue supply main pipe 51, which communicates with the interior of the glue supply main pipe 51. The connector 53 is a ring structure and is rotatably sleeved on the glue supply main pipe 51. The connector 53 is hollow inside, and an opening is provided on the inner side wall of the connector 53. The interior of the glue supply main pipe 51 communicates with the interior of the connector 53. The end of the flexible glue tube 52 away from the glue outlet block 42 communicates with the interior of the connector 53. Connecting rods 54 are provided on both sides of the connector 53 perpendicular to the length direction of the glue supply main pipe 51. The two ends of the two connecting rods 54 that are far apart from each other are welded to two rotating disks 31, so that the connector 53 can rotate together with the rotating disks 31, reducing the occurrence of the flexible glue tube 52 getting tangled on the glue supply main pipe 51.

[0057] Reference Figure 2 and Figure 3 A drive assembly 9 for driving the rotating disk 31 is provided on the support plate. The drive assembly 9 includes a driven gear 92, a driving gear 91, and a drive component 93. The driven gear 92 has a through hole coaxially and is coaxially sleeved on the glue supply manifold 51, and can rotate around its own axis. The side of the driven gear 92 closest to the rotating disk 31 is welded to the rotating disk 31, and the rotation of the driven gear 92 can drive the rotating disk 31 to rotate. The driving gear 91 is rotatably connected to the support plate and meshes with the driven gear 92. The drive component 93 is mounted on the support plate and is used to drive the driving gear 91 to rotate. In this embodiment, the drive component 93 is a servo motor. The housing of the servo motor is welded to the support plate, and the output shaft of the servo motor is coaxially welded to the driving gear 91. The rotation of the output shaft of the servo motor can drive the driving gear 91 to rotate, thereby driving the rotating disk 31 to rotate.

[0058] Reference Figure 2 , Figure 3 and Figure 4For ease of description, the two planes of the slide plate 41 parallel to its own axis are defined as radial planes. A locking assembly 6 is provided inside the slide plate 41 to limit the movement of the dispensing block 42. The locking assembly 6 includes two abutment plates 61. Each of the two radial planes has a groove extending through it in a direction parallel to the axis of the slide plate 41. The abutment plate 61 is a long strip structure, embedded in the groove, and can slide in a direction perpendicular to the radial plane. Sliding the abutment plate 61 allows the side of the abutment plate 61 closest to the dispensing block 42 to press against the dispensing block 42. Under the action of friction, the abutment plate 61 can prevent the dispensing block 42 from moving, thereby limiting the movement of the dispensing block 42.

[0059] Reference Figure 4 , Figure 5 and Figure 6 The locking assembly 6 also includes a pull plate 62 and a push rod 63. A groove is formed on the side of the slide plate 41 away from the drive member 93. The pull plate 62 slides within the groove in a direction parallel to the axis of the slide plate 41. Two sets of push rods 63 are provided corresponding to the two abutment plates 61. Each set of push rods 63 includes multiple push rods 63 spaced in a square pattern parallel to the axis of the slide plate 41; in this embodiment, three push rods are provided. One end of the push rod 63 is vertically welded to the side of the abutment plate 61 away from the adhesive outlet 42, and the other end extends towards the pull plate 62. A drive groove is formed on the side of the pull plate 62 corresponding to the push rod 63. The drive groove includes a drive slope 631, which slopes from the side near the drive member 93 towards the side away from the drive member 93, moving away from the push rod 63. A contact surface is provided at the end of the push rod 63 near the pull plate 62, which engages with the drive slope 631. Sliding the pull rod away from the drive component 93, under the action of the drive inclined surface 631, can drive the push rod 63 to move closer to the dispensing block 42, thereby causing the clamping rod to press against the dispensing block 42, thus limiting the dispensing block 42.

[0060] Reference Figure 7 and Figure 8 A linkage assembly 7 is provided on the rotating disk 31, which is away from the driving component 93. The linkage assembly 7 is used to drive multiple pull plates 62 to move simultaneously. The linkage assembly 7 includes a lever 71 and a support 72. The side of the pull plate 62 away from the driving component 93 extends through the rotating disk 31 to the side of the rotating disk 31 away from the slide plate 41. Multiple levers 71 and supports 72 are provided corresponding to the pull plates 62. The supports 72 are welded to the rotating disk 31, and the levers 71 are rotatably connected to the supports 72, with one end of the levers 71 passing through the pull plates 62. A rotating groove is provided on the pull plate 62 at the position corresponding to the lever 71, allowing the lever 71 to rotate within the rotating groove and slide along its own length. Rotating the lever 71 causes it to abut against the side wall of the rotating groove, thereby applying a force to the pull plate 62 to move it away from the slide plate 41, thus driving the pull plate 62 to move.

[0061] Reference Figure 7 , Figure 8 , Figure 9 and Figure 10 The linkage assembly 7 also includes a linkage ring 73 and a mounting ring 74. The mounting ring 74 is a circular ring structure and is coaxially welded to the side of the rotating disk 31 near the lever 71. The mounting ring 74 is also sleeved on the outside of the glue supply manifold 51. The linkage ring 73 is also a circular ring structure and is coaxially sleeved on the outside of the mounting ring 74. The outer wall of the mounting ring 74 has an external thread, and the inner wall of the linkage ring 73 has a threaded groove that mates with the external thread. The external thread slides within the threaded groove. Rotating the linkage ring 73 allows it to slide parallel to the axis of the mounting ring 74 under the action of the thread. The outer wall of the linkage ring 73 has an annular groove 731. The end of the lever 71 furthest from the pull plate 62 is inserted into the annular groove 731, and the lever 71 slides relative to the linkage ring 73 within the annular groove 731 during rotation. Rotating the linkage ring 73 also allows it to move closer to the rotating disk 31 under the action of the thread. After the side wall of lever 71 abuts against the side of annular groove 731 perpendicular to its own axis, the linkage ring 73 drives the end of lever 71 away from pull plate 62 to rotate towards the rotating disk 31. This causes the end of lever 71 near pull plate 62 to move pull plate 62 away from slide plate 41, achieving simultaneous adjustment of the positions of multiple pull plates 62.

[0062] Reference Figure 7 , Figure 8 , Figure 9 and Figure 10 Two rotating balls 75 are respectively provided at both ends of the lever 71, and the positions of the rotating balls 75 correspond to the positions of the pull plate 62 and the annular groove 731. The sidewall of the rotating groove is arc-shaped, and the rotating ball 75 closer to the pull plate 62 is embedded in the rotating groove and can rotate freely. The two end faces of the annular groove 731 perpendicular to its own axis are provided with annular ball grooves 732, and the sides of the ball grooves 732 are arc-shaped. The rotating ball 75 away from the pull plate 62 is embedded in the ball grooves 732, and the rotating ball 75 can rotate around the axis of the linkage ring 73 within the ball grooves 732 and can rotate freely around its own center. Through holes are coaxially provided on the rotating balls 75, and the two ends of the lever 71 slide through the through holes of the two rotating balls 75. The rotating balls 75 compensate for the gaps between the rotating groove and the lever 71, and between the annular groove 731 and the lever 71, thereby making the movement of the pull plate 62 driven by the linkage ring 73 more stable.

[0063] Reference Figure 7 , Figure 8 and Figure 9To facilitate the rotation of the linkage ring 73, an adjustment assembly 8 is also provided on the mounting ring 74. The adjustment assembly 8 includes two adjustment rings 81, positioned on opposite sides of the linkage ring 73 along a direction parallel to its axis. Each adjustment ring 81 is a circular ring structure, fitted onto the mounting ring 74 and capable of rotating around its own axis. The adjustment rod 82 is a cylindrical rod located between the two adjustment rings 81. A through hole is provided on the linkage ring 73 corresponding to the position of the adjustment rod 82. The adjustment rod 82 passes through this through hole. Both ends of the adjustment rod 82 are welded to the adjacent sides of the two adjustment rings 81. Rotating the adjustment ring 81 causes the adjustment rod 82 to rotate, which in turn rotates the linkage ring 73.

[0064] Reference Figure 7 , Figure 8 and Figure 9 The adjusting assembly 8 also includes a bevel gear disk 83 and a driving bevel gear 84. The bevel gear disk 83 is coaxially welded to the side of the adjusting ring 81 away from the linkage ring 73. The driving bevel gear 84 is rotatably connected to the mounting ring 74 and meshes with the bevel gear disk 83. Rotating the driving bevel gear 84 can drive the bevel gear disk 83 to rotate, thereby adjusting the linkage ring 73.

[0065] Reference Figure 7 , Figure 8 and Figure 9 The adjustment assembly 8 also includes an auxiliary rod 85, which is a cylindrical structure. One end of the auxiliary rod 85 is coaxially welded to the drive bevel gear 84. The end of the auxiliary rod 85 away from the drive bevel gear 84 has a hexagonal groove, which matches a hexagonal wrench. The operator can use the hexagonal wrench to rotate the drive bevel gear 84 to adjust the linkage ring 73.

[0066] Reference Figure 3 and Figure 7 The adjusting assembly 8 also includes a protective housing 86, which covers the bevel gear disk 83 and the driving bevel gear 84, and is welded to the mounting ring 74. The protective housing 86 protects the bevel gear disk 83 and the driving bevel gear 84, thus extending their service life. A through hole is provided on the protective housing 86 corresponding to the position of the auxiliary rod 85, allowing operators to easily rotate the auxiliary rod 85 through the through hole.

[0067] Reference Figure 2 After the base paper is coated with adhesive, subsequent processes such as lamination and cutting are carried out (not shown in the figure) to complete the label production and processing.

[0068] The implementation principle of the anti-counterfeiting and anti-theft label and its adhesive coating equipment in this application embodiment is as follows: The operator can use a hex wrench to rotate the auxiliary rod 85; as the auxiliary rod 85 rotates, the active bevel gear 84 drives the bevel gear disk 83 to rotate. The rotation of the bevel gear disk 83 drives the adjusting ring 81 to rotate, thereby adjusting the linkage ring 73. When the linkage ring 73 moves away from the rotating disk 31, it drives the pull plate 62 to move closer to the sliding plate 41. At this time, the clamping plate 61 no longer presses against the adhesive dispensing block 42, and the operator can move the adjusting block according to the shape of the first adhesive layer 12 to adjust the position of the adhesive dispensing block 42. After the position of the adhesive dispensing block 42 is adjusted, the auxiliary rod 85 is adjusted by using a hex wrench to drive the linkage component 7 to operate, thereby locking the adhesive dispensing block 42. Finally, after the position of the adhesive dispensing block 42 is adjusted, the solenoid valve corresponding to the specific adhesive dispensing block 42 is activated by the PLC program to supply adhesive to the adhesive dispensing block 42. This drives the adhesive coating device 3, the rotating disk 31 rotates, and the adhesive dispensing block 42 contacts the base paper, completing the adhesive coating process.

[0069] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
