[0015] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0016] As shown in Figures 1 to 9, the fully automatic rubber band molding machine includes a control center 13, a rack 1, and a machine frame 12 fixed to the rack 1. The control center 13 controls various solenoid valves to operate the cylinders. A main guide rail 11 is provided at the lower end of the machine frame 12, and a corresponding sub-guide rail 6 is provided at the upper end of the machine frame 12. A discharge mechanism 8 is provided at the end of the main guide rail 11. A pulling plate 10 and a guide plate 3 are slidably connected to the main guide rail 11 to guide and pull the rubber band. A thermal cutting mechanism 4 is provided between the pulling plate 10 and the guide plate 3. The thermal cutting mechanism 4 includes a cutter holder 41 and a wire ironing module 42. The thermal cutting mechanism 4 flattens and cuts the raw material with an iron to make the ends of the rubber band round and smooth. An adhesive application mechanism 7 is provided between the pulling plate 10 and the discharge mechanism 8. The adhesive application mechanism 7 includes an adhesive assembly 71 and a rotating post-clamping unit 72 associated with it. A front clamping unit 5 associated with the rotating post-clamping unit 72 is slidably mounted on the sub-guide rail 6. The front clamping unit 5 transports the rubber band to the corresponding rotating post-clamping unit 72 of the adhesive application mechanism 7, where it precisely applies adhesive to the rubber band at multiple points to bond it, ensuring a uniform adhesive application. Finally, the discharge mechanism 8 clamps and discharges the formed rubber band. In this way, a fully automated production process is achieved, from material supply, thermal cutting, bonding, and discharge. This mechanized production stabilizes the quality of rubber bands, significantly improves production efficiency, and reduces labor costs.

[0017] The guide plate 3 is provided with a wire crossbar 32. After passing through the wire crossbar 32, the material enters the guide clip 33 and passes through the wire hole 31. As the guide plate 3 slides forward on the main guide rail 11 driven by the cylinder, the guide clip 33 engages with the rubber band under the drive of the wire cylinder 34 to prevent it from coming off, and the wire ironing module 42 completes the wire ironing operation. After the wire ironing process is completed, the guide plate 3 slides backward, and the guide clip 33 opens, completing the wire guiding process. The guide plate 3 then slides forward again to clamp the rubber band. This reciprocating motion forms an automated wire guiding process.

[0018] The wire ironing module 42 includes an ironing rack 421 driven by a cylinder and capable of reciprocating laterally relative to the frame 12, an upper wire ironing plate 423 mounted on the ironing rack 421 by a fourth telescopic cylinder 422 so as to be movable up and down, and a lower wire ironing plate 424 corresponding to the upper wire ironing plate 423. The lower wire ironing plate 424 is mounted on the frame 12 so as to be reciprocally movable laterally relative to the frame 12 by a gear rack 425 driven by a cylinder.

[0019] In operation, the upper wire ironing plate 423 descends to approach the lower wire ironing plate 424 and cooperates with the lower wire ironing plate 424 to firmly press the rubber band. Then, the wire ironing module 42 slides leftward and the lower wire ironing plate 424 slides rightward, completing the hot wire treatment. After that, the upper wire ironing plate 423 rises and separates from the lower wire ironing plate 424, and the wire ironing module 42 and the lower wire ironing plate 424 return to their original positions to further cooperate with the wire process.

[0020] Twenty-six wire holes 31 are arranged in a row on the side of the guide plate 3 corresponding to the thermal cutting mechanism 4. The pulling plate 10 is provided with pull clips 101 that open and close with the tension cylinder 102. The pulling plate 10 is driven by the third telescopic cylinder 35 to slide on the main guide rail 11, moving towards and away from the guide plate 3. The wire holes 31 separate the materials individually, preventing the rubber bands from getting tangled and affecting production.

[0021] During operation, the pulling plate 10 slides forward to the position of the conductor hole 31, and the pull clip 101 engages to clamp the end of the cut rubber band, completing the clamping of the rubber band. Next, the pulling plate 10 is driven by a cylinder to slide backward, transporting the rubber band forward, and the cutter holder 41 performs the cutting operation again. The pull clip 101 opens, and the front clamping unit 5 clamps the rubber band, completing the removal of the material by pulling and cutting. Then, the pulling plate 10 slides forward again to clamp the end of the rubber band. By repeating this process, an automated wire pulling and wire cutting process is completed.

[0022] The front clamping unit 5 according to this embodiment includes a fourth clamp module 51, a main front clamp plate 52, and a sub-front clamp plate 53. The upper part of the main front clamp plate 52 is connected to the sub-guide rail 6 by being pulled by a sixth telescopic cylinder 55 so as to be slidable thereon. The fourth clamp module 51 is pulled by a first telescopic cylinder 54 and is provided so as to be able to rise and fall on the main front clamp plate 52. The sub-front clamp plate 53 is provided so as to be able to rise and fall on the fourth clamp module 51.

[0023] After the wire pulling process is completed, the fourth clamping module 51 descends to a height corresponding to the conductor hole 31 to clamp the rubber band. The fourth clamping module 51 then ascends to complete the rubber band clamping process. The front clamping unit 5 then slides backward to a position corresponding to the post-rotation clamping unit 72, and the fourth clamping module 51 descends again to approach the post-rotation clamping unit 72 and butt the rubber band. The fourth clamping module 51 then ascends again, and the front clamping unit 5 slides forward to its initial position, thereby completing the rubber band butt process. The fourth clamping module 51 then descends again to clamp the rubber band. This reciprocating movement achieves automatic rubber band transport. This series of operations ensures accurate alignment of the rubber band, prevents misalignment, and accurately completes transport and butt processing.

[0024] In addition, a spring is provided on the corresponding slide rail of the auxiliary front clamping plate 53. When the fourth clamping module 51 descends, the spring is compressed, and when the fourth clamping module 51 ascends, the elasticity of the spring reduces the tensile force required by the first telescopic cylinder 54. This prevents malfunctions due to insufficient power of the first telescopic cylinder 54 and ensures a smooth completion of the rubber band transport process.

[0025] The adhesive assembly 71 includes a dispenser tray 713 mounted on the frame 12 and a dispenser holder 712 that slides onto the main guide rail 11. The dispenser holder 712 is provided with a liftable dispenser needle 711. The post-rotation clamping unit 72 includes a first clamping module 722, a second clamping module 723, a first rotating cylinder 721, and a second rotating cylinder 724. The first rotating cylinder 721 is fixed to one side of the first clamping module 722 and drives the first clamping module 722 to rotate on its axis. The second rotating cylinder 724 is fixed to one side of the second clamping module 723 and drives the second clamping module 723 to rotate on its axis. The liftable dispenser needle 711 is driven by a second telescopic cylinder 714 to reciprocate between the dispenser tray 713 and the post-rotation clamping unit 72. This allows the rubber bands to be accurately aligned, preventing misalignment and ensuring accurate joining and bonding.

[0026] During operation, the first clamping module 722 and the second clamping module 723 operate synchronously to clamp the rubber band supplied from the front clamping unit 5. Next, the first clamping module 722 rotates 90° clockwise, and the second clamping module 723 simultaneously rotates 90° counterclockwise, bringing them close together and closing the rubber band into a circular shape (i.e., bonding the two ends of the rubber band together). The dispenser needle 711 then descends and enters the dispenser tray 713 to impregnate it with adhesive. After the dispenser needle 711 returns to its original position, the dispenser holder 712, driven by the seventh telescopic cylinder 715, slides forward to a position corresponding to bonding the rubber band. The dispenser needle 711 then moves downward, bonding and butting the tip of the needle against the end of the rubber band. The first clamping module 722 then rotates 90° clockwise and slides forward to bond with the second clamping module 723, which then rotates 90° counterclockwise. This activates the corresponding clamping module of the discharge mechanism 8 to remove the rubber band. The first clamping module 722 then slides backward and rotates 180° counterclockwise, while the second clamping module 723 rotates 180° counterclockwise, with the aforementioned clamping modules operating in sync to clamp the rubber band again. Repeating this series of operations completes the fully automatic rubber band bonding and joining process.

[0027] The discharge mechanism 8 includes a discharge rack 81 mounted on the machine frame 12. The discharge rack 81 is provided with a material discharge plate 83 that can slide freely back and forth by a fifth telescopic cylinder 84. A discharge cylinder 82 is further provided above the discharge rack 81 so that the material discharge plate 83 can be raised and lowered. A third clamp module 85 that corresponds to the post-rotation clamping unit 72 is provided at the end of the material discharge plate 83.

[0028] Following the precise dispensing process described above, the discharge plate 83 slides forward so that the third clamping module 85 is aligned with the rubber band and clamps the rubber band in the third clamping module 85. The discharge plate 83 then returns to its original position and descends, the third clamping module 85 lowers the rubber band, and the discharge plate 83 moves up to complete the rubber band discharge. Next, the discharge plate 83 slides forward again to clamp the rubber band in the third clamping module 85. This reciprocating motion forms a fully automatic discharge process.

[0029] The third clamping module 85 is rotatably connected to the material output plate 83 via a position-regulating rotary plate 86. A displacement protrusion 87 is provided at the front end of the output rack 81, which contacts the third clamping module 85 during the sliding process. When the material output plate 83 slides forward, the displacement protrusion 87 rotates the third clamping module 85 by a certain angle, so that the rubber band in the corresponding clamping unit 72 can be more easily clamped after rotation.

[0030] A wire ejection mechanism 9 is provided on the side of the machine frame 12 corresponding to the third clamp module 85. The wire ejection mechanism 9 is composed of a conveying chain 92 driven by a cylinder and a wire ejection tool 93 attached to the conveying chain 92. When the cylinder operates one stroke, the corresponding gear set 91 rotates in conjunction with the movement of the conveying chain 92, and at the same time, the wire ejection tool 93 snaps the rubber band on the discharge plate 83, causing the wire to easily drop onto the box frame 1, completing the discharge process.

[0031] A material rack 2 is provided in front of the machine frame 12. Above the material rack 2, symmetrical arrangements of wire sorting pins 21 are provided, each connected by 26 small bolts. Between the wire sorting pins 21, there are wire rods 22 driven by cylinders. When multiple rubber bands are used, each rubber band can be individually threaded through the wire sorting pins 21 to prevent the multiple rubber bands from becoming entangled. As the wire rods 22 move downward, they pull the rubber bands and move downward together, completing the material supply process.

[0032] The above examples are merely illustrative for the purpose of clarifying the present invention and are not intended to limit the embodiments. Those skilled in the art will be able to make various modifications and improvements based on the above description. It is not necessary to cover all examples here. Therefore, all modifications and improvements are intended to fall within the scope of protection of the present invention. [Explanation of symbols]
