[0002] Inlay refers to a pre-laminated product composed of multiple layers of PVC sheets containing chips and coils, generally consisting of two or three layers. Generally speaking, there is no printed pattern on the surface. Inlay is an advanced form of digital label. By integrating Inlay into the label, the function of the label is significantly expanded. This integration enables the label to achieve more advanced automatic identification and data management. It is widely used in various industries, especially in the clothing industry.

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.

[0033] In a further embodiment, referring to Figure 2-Figure 4 The conveying mechanism 2 includes a conveying frame 21 and a transmission component 22. The inner wall of the box body 1 is fixedly connected with a connecting block 12. The front end of the connecting block 12 is fixedly connected with the conveying frame 21. The right end of the conveying frame 21 penetrates the right end of the box body 1. The conveying frame 21 is provided with a transmission component 22. The box body 1 is fixedly connected with a guide plate 11. The left end of the conveying frame 21 penetrates the upper end of the guide plate 11. The transmission component 22 includes a conveying roller 221 and a conveying belt 222. The left and right ends of the conveying frame 21 are rotatably connected with the conveying roller 221. The conveying frame 21 is located at the conveying frame 21. There are two groups of conveying rollers 221 at the left and right ends. The conveying rollers 221 located at the left and right ends of the conveying frame 21 are connected through a conveyor belt 222. There are two groups of conveyor belts 222 and they are respectively located on the front and back sides of the conveying rollers 221. The front ends of the two groups of conveying rollers 221 located on the left side of the conveying frame 21 are fixedly connected to the first gear 223. The two groups of first gears 223 are meshed with each other. The rear end of the conveying frame 21 is fixedly connected to the first motor 224. The conveying frame 21 is fixedly connected to a stop block 23 inside. The stop block 23 is located between the two groups of conveyor belts 222.

[0034] In this embodiment, the first motor 224 is started to drive the conveying roller 221 to rotate, and the rotation of the conveying roller 221 drives the first gear 223 to rotate. Since the two groups of first gears 223 are meshed with each other, the two groups of conveying rollers 221 are driven to rotate at the same time. The conveying rollers 221 on the left and right sides of the conveying frame 21 are connected through the conveyor belt 222, thereby driving the conveyor belt 222 to move. The movement of the upper and lower groups of conveyor belts 222 can drive the label clamped and fixed between the conveyor belts 222 to move. When the label moves to the bottom of the stop block 23, the substrate and Inlay of the label can be effectively separated by the material transfer mechanism 4 under the conveyor belt 222. The separated substrate is moved to the guide plate 11 through the conveyor belt 222, thereby achieving the effect of driving the label to move to the specified position for processing.

[0035] In a further embodiment, referring to Figure 2-Figure 3 A heating mechanism 3 is provided at the upper end of the connecting block 12. The heating mechanism 3 includes an electric hot air blower 31 and a heating head 32. The electric hot air blower 31 is fixedly connected to the upper end of the connecting block 12. The heating head 32 is fixedly connected to the left end of the electric hot air blower 31. The lower end of the heating head 32 penetrates into the interior of the conveying rack 21.

[0036] In this embodiment, when the label is moved by the conveyor belt 222, the electric hot air blower 31 works, so that the high-temperature wind generated is discharged through the heating head 32, and then the moving label can be heated, thereby softening the adhesive on the label, preparing for the subsequent separation of the label substrate and the Inlay.

[0037] In a further embodiment, referring to Figure 5-Figure 7 The material transfer mechanism 4 includes a bracket 41 and a negative pressure component 49. The bracket 41 is fixedly connected inside the box body 1. The front end of the bracket 41 is fixedly connected to a limiting guide rod 42. The side wall of the limiting guide rod 42 is slidably connected to a moving block 43. The upper end of the bracket 41 is fixedly connected to an electric telescopic rod 44. The output shaft end of the electric telescopic rod 44 is fixedly connected to the upper end of the moving block 43. The front end surface of the bracket 41 is sequentially provided with a second limiting groove 413, a C-shaped groove 412 and a first limiting groove 411 from top to bottom. The C-shaped groove 412 is connected to the second limiting groove 4 13 and the first limiting groove 411 are connected to each other, a rotating shaft 45 is rotatably connected inside the movable block 43, a first connecting rod 46 is fixedly connected to the rear end of the rotating shaft 45, a limiting block 461 is fixedly connected to the upper rear end of the first connecting rod 46, the limiting block 461 is located inside the first limiting groove 411 and is slidably connected, a second connecting rod 47 is fixedly connected to the front end of the rotating shaft 45, a mounting plate 48 is fixedly connected to the lower end of the second connecting rod 47, the mounting plate 48 is located directly below the stop block 23, and a negative pressure component 49 is provided on the side wall of the mounting plate 48.

[0038] In this embodiment, the moving block 43 is driven to move upward by starting the electric telescopic rod 44, and the moving block 43 moves upward to drive the rotating shaft 45 to move upward, and then the limiting block 461 is driven to move upward through the first connecting rod 46. When the limiting block 461 moves to the C-shaped groove 412, the rotating shaft 45 is driven to rotate through the first connecting rod 46. When the limiting block 461 moves to the connection between the C-shaped groove 412 and the second limiting groove 413, the rotating shaft 45 rotates 180 degrees, thereby achieving the effect of rotating the position of the suction cup 494 under the mounting plate 48.

[0039] In a further embodiment, referring to Figure 5-Figure 7 The negative pressure component 49 includes a suction cup 494 and a connecting pipe 493. A negative pressure machine 491 is fixedly connected to the inside of the box body 1. A delivery pipe 492 is fixedly connected to the side wall of the negative pressure machine 491. A connecting pipe 493 is fixedly connected to the free end of the delivery pipe 492. A connecting branch pipe 495 is equidistantly fixedly connected to the side wall of the connecting rod. The lower end of the connecting branch pipe 495 passes through the lower end of the mounting plate 48. Suction cups 494 are fixedly connected to the lower end of the connecting branch pipe 495 at an equidistant distance. The suction cups 494 are fixedly connected to the lower end of the connecting branch pipe 495.

[0040] In this embodiment, when the suction cup 494 is in contact with the Inlay, the negative pressure machine 491 is started to generate negative pressure in the delivery tube 492. Since the delivery tube 492 is connected with the connecting tube 493 and the connecting branch tube 495, the suction cup 494 generates negative pressure, so that the Inlay can be tightly adsorbed, providing a fixing effect for the transfer of the Inlay.

[0041] In a further embodiment, referring to Figure 8-Figure 9 A clamping guide mechanism 5 is provided inside the box body 1, and the clamping guide mechanism 5 is located below the mounting plate 48. The clamping guide mechanism 5 includes a connecting plate 51 and a guide roller 52. The connecting plate 51 is fixedly connected inside the box body 1. Both left and right ends of the connecting plate 51 are rotatably connected to the guide rollers 52 through bearing seats. The upper left end of the connecting plate 51 is rotatably connected to a third connecting rod 53 through a bearing seat. The front left end of the third connecting rod 53 is rotatably connected to a pressure roller 54, and the pressure roller 54 abuts against the guide roller 52. The lower end of the third connecting rod 53 is fixedly connected to a spring 55, and the lower end of the spring 55 is fixedly connected to the upper end of the bearing seat.

[0042] In this embodiment, when the release paper in the recovery mechanism is located above the connecting plate 51 and between the pressure roller 54 and the guide roller 52, the material transfer mechanism 4 is responsible for accurately moving and placing the Inlay on the upper end of the release paper, and then pressing it. As the release paper moves further, when it reaches below the pressure roller 54, the Inlay is effectively fixed on the release paper under the joint action of the pressure roller 54 and the guide roller 52, thereby ensuring the stable adhesion of the Inlay.

[0043] In a further embodiment, referring to Figure 8-Figure 10 The recycling device 6 includes a paper supply card tube 64 and a paper collection card tube 63. A mounting frame 61 is fixedly connected inside the box body 1. The left and right sides of the front end of the mounting frame 61 are rotatably connected with a rotating shaft 62. The side wall of the rotating shaft 45 on the left side of the mounting frame 61 is slidably connected with the paper collection card tube 63. The side wall of the rotating shaft 45 on the right side of the mounting frame 61 is slidably connected with the paper supply card tube 64. The side wall of the rotating shaft 45 on the left side of the mounting frame 61 is fixedly connected with a third gear 67. A second motor 65 is fixedly connected inside the mounting frame 61. A second gear 66 is fixedly connected to the output shaft end of the second motor 65. The second gear 66 and the third gear 67 are meshed with each other.

[0044] In this embodiment, the paper supply card cylinder 64 and the paper receiving card cylinder 63 are moved to the rotating shaft 62, and then the free end of the release paper on the paper supply card cylinder 64 is fixed to the paper receiving card cylinder 63. When the free end of the release paper is fixed, the lower end surface of the release paper abuts against the guide roller 52. Then, the second motor 65 is started to drive the second gear 66 to rotate, and the second gear 66 rotates to drive the third gear 67 to rotate. The third gear 67 rotates to drive the rotating shaft 62 on the left side of the mounting frame 61 to rotate, and the rotating shaft 62 rotates to drive the paper receiving card cylinder 63 to rotate, so that the release paper with Inlay can be rolled up.

[0045] The working principle of the present invention is as follows: the length of the label is inputted into the controller 7, and then the label is placed at the right end of the conveyor frame 21 with the side with the Inlay facing downward, and then the first motor 224 is started to drive the conveyor roller 221 to rotate, and the rotation of the conveyor roller 221 drives the first gear 223 to rotate. Since the two groups of first gears 223 are meshed with each other, the two groups of conveyor rollers 221 are driven to rotate at the same time, and the conveyor rollers 221 on the left and right sides of the conveyor frame 21 are connected through the conveyor belt 222, thereby driving the conveyor belt 222 to move. The movement of the upper and lower groups of conveyor belts 222 can drive the label clamped between the conveyor belts 222 to move, and when the label passes to the heating head 3 2, the high-temperature wind generated by the electric hot air blower 31 is discharged through the heating head 32, thereby heating the moving label, thereby softening the adhesive on the label. Then, when the label moves to the bottom of the stop block 23, the moving block 43 is driven to move upward by the electric telescopic rod 44, and the moving block 43 moves upward to drive the rotating shaft 45 to move upward, and then the limiting block 461 is driven to move upward by the first connecting rod 46. When the limiting block 461 moves to the C-shaped groove 412, the rotating shaft 45 is driven to rotate by the first connecting rod 46. When the limiting block 461 moves to the connection between the C-shaped groove 412 and the second limiting groove 413, the rotating shaft 45 rotates 1 80 degrees, and then continue to drive the suction cup 494 upward, so that the suction cup 494 abuts against the Inlay in the label, and then start the negative pressure machine 491 to generate negative pressure in the conveying pipe 492. Since the conveying pipe 492 is connected with the connecting pipe 493 and the connecting branch pipe 495, the suction cup 494 generates negative pressure, so that the Inlay can be tightly adsorbed, and then the suction cup 494 is driven to move downward by starting the electric telescopic rod 44, so as to separate the Inlay from the substrate and move the Inlay above the release paper to complete the initial fixation of the Inlay on the release paper, and then the suction cup 494 moves upward through the electric telescopic rod 44 to prepare for the next material transfer. The operation provides necessary power; at the same time, the Inlay fixed on the release paper is driven by the second motor 65 to rotate, the second gear 66 rotates to drive the third gear 67 to rotate, the third gear 67 rotates to drive the rotating shaft 62 on the left side of the mounting frame 61 to rotate, the rotating shaft 62 rotates to drive the paper receiving card cylinder 63 to rotate, and the rotating paper receiving card cylinder 63 drives the release paper to move, so that the Inlay fixed on the release paper passes between the pressing roller 54 and the guide roller 52, so that the Inlay is further fixed on the release paper, and then rolled into the paper receiving card cylinder 63, thereby improving the recovery efficiency of the Inlay and realizing its recycling.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
