[0004] The aforementioned patent has enabled the automated mass production of elastic bands, greatly improving production efficiency and shortening the production cycle. However, it uses a method of stretching and flipping the elastic band into a loop. This method is prone to deviation, misalignment, or overlap at both ends of the elastic band during the flipping process, resulting in unsatisfactory quality of the finished product. To solve this problem, this application proposes a new solution. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the present utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0022] An energy-efficient and high-performance automatic tape splicing machine, such as Figure 1 As shown, the machine includes a frame 1, a platform 2 on top of the frame 1, a conveyor 3 on one side of the edge of the platform 2, a feeding bracket 4 on the end of the conveyor 3 away from the platform 2, and a pressing and cutting mechanism 5 on the other end of the platform 2. Before using the equipment, the elastic band material needs to be placed on the feeding bracket 4, then pulled and installed on the conveyor 3. A pulling and traction mechanism 6 is provided on the side of the pressing and cutting mechanism 5 away from the conveyor 3. The pulling and traction mechanism 6 and the pressing and cutting mechanism 5 are connected. A clamping mechanism 7 is provided between the cutting mechanisms 5, and a sewing fastening machine 8 is provided on the table 2. The sewing fastening machine 8 is aligned with the clamping mechanism 7. The elastic band will be bent and wound at the pressing and cutting mechanism 5 on the transmission table 3, and then pulled outward by the pulling mechanism 6, so that the elastic band forms a loop. Then the pressing and cutting mechanism 5 will press and cut it, and the clamping mechanism 7 will clamp and stabilize it. Finally, the clamping mechanism 7 will transport it to the sewing fastening machine 8 to sew and fasten the pressing and cutting position.

[0023] like Figure 2As shown, the pressing and cutting mechanism 5 includes a mounting bracket 9, a transmission roller 10, a cutting blade 11, a cylinder 12, a pressure plate 13, and an ultrasonic mold 14. The mounting bracket 9 is located on the top of the transmission table 3 near the end of the table plate 2. The transmission roller 10 rotates and is rotatably mounted on the bottom of the mounting bracket 9. The cylinder 12 is fixed to the top of the mounting bracket 9, and its output end is fixed to the cutting blade 11. The pressure plate 13 is mounted on the transmission table 3 and offset from the cutting blade 11. The ultrasonic mold 14 is mounted on the transmission table 3 and aligned with the cutting blade 11. During installation, the elastic band is first pulled to the transmission roller 10, passes around the top of the transmission roller 10, is then pulled to the pressure plate 13, passes around the front of the pressure plate 13 to its bottom, and is then pulled backward to the bottom of the transmission roller 10. The bottom of the transmission roller 10 is equipped with a roller driven by a motor. The end of the elastic band is clamped in the transmission roller 10. Between the moving roller 10 and the driving roller; the pulling and traction mechanism 6 can pull the elastic band of the pressing and cutting mechanism 5 outward. Since the elastic band on the bottom side of the pressure plate 13 is clamped, the elastic band on the top side will be pulled out to form a loop. At this time, the elastic band on the ultrasonic mold 14 will overlap and align. Then, the cylinder 12 drives the cutting blade 11 to move downward. The downward-moving cutting blade 11 will first press down on the elastic band on the top side of the pressure plate 13. When the upper and lower elastic bands come into contact, due to the setting of the ultrasonic mold 14, the two ends will be ultrasonically pressed together. After pressing, the cutting blade 11 will continue to press down and cut, forming a complete elastic band loop. Since the pressing is performed in an overlapping and aligned state before cutting, it can avoid the situation of inaccurate alignment or overlapping of the two ends after alignment caused by the existing tape splicing machine that cuts first and then flips and aligns the ends.

[0024] like Figure 3 As shown, the traction mechanism 6 includes a hook assembly for hooking the elastic band and a drive assembly for driving the hook assembly to move back and forth. The drive assembly includes a mounting bracket 18, a timing belt slide 19, a timing belt slider 20, an extension bracket 21, and a connecting plate 22. The mounting bracket 18 is an L-shaped wide plate, placed horizontally, with one end fixed to the platform 2 and the other end vertically upward. The timing belt slide 19 is fixed to the vertically positioned end of the mounting bracket 18. The length direction of 9 is the same as that of the platform 2. The timing belt slider 20 is slidably mounted on the timing belt slide table 19. It can slide along the timing belt slide table 19, moving closer to or away from the pressing and cutting mechanism 5. The extension bracket 21 is a rectangular long plate. One end of it is fixed to the timing belt slider 20, and the other end faces the pressing and cutting mechanism 5. The connecting plate 22 is also an L-shaped wide plate, placed vertically. One end is fixed to the extension bracket 21, and the other end extends away from the timing belt slide table 19.

[0025] like Figure 3 As shown, the hook assembly specifically includes a hook rod 15, an extension bracket 16, and a cylinder 17. The cylinder 17 is fixed to the connecting plate 22, and its output end is fixed to the extension bracket 16. The extension bracket 16 is a vertical and inverted L-shaped narrow plate, connected to the cylinder 17 at one end (side) and extending towards the pressing and cutting mechanism 5 at the other end. The hook rod 15 is fixedly mounted on the end of the extension bracket 16 extending towards the pressing and cutting mechanism 5, and the length direction of the hook rod 15 is the same as the movement direction of the output end of the cylinder 17. Therefore, the entire hook assembly, driven by the synchronous belt slider 20, can move closer to or further away from the pressing and cutting mechanism 5. Under the drive of the cylinder 17, the extension bracket 16 can move outward or inward in the horizontal direction. When the extension bracket 16 is in the inward position close to the cylinder 17, the hook rod 15 is aligned with the elastic band. Therefore, when the elastic band is installed on the transmission table 3... After tightening, the timing belt slider 20 moves toward the elastic band, causing the entire hook assembly to move toward the elastic band as well. Simultaneously, cylinder 17 drives the extension bracket 16 to move outward, causing the end of the hook rod 15 to move out of alignment with the elastic band. The hook rod 15 continues to move forward to between the transmission roller 10 and the pressure plate 13. Then, cylinder 17 drives the extension bracket 16 to move inward, causing the hook rod 15 to move to the inside of the elastic band. The timing belt slider 20 then drives the entire hook assembly to move back, and the hook rod 15 hooks the elastic band and pulls it outward, causing the elastic band to be pulled out and form a loop. Finally, cylinder 12 is activated to drive the cutting blade 11 to move downward, pressing and cutting the elastic band, thus completing the forming of the elastic band. A small knot of waste material will be generated at the pressing point. At this time, the side of the elastic band below the transmission roller 10 will be driven by the roller to continue moving downward a short distance to ensure that repeated pressing does not occur and to ensure the quality of the finished elastic band.

[0026] like Figure 4 As shown, the clamping mechanism 7 includes a clamping assembly for clamping the elastic band and a second driving assembly for driving the clamping assembly to move. The second driving assembly includes a second synchronous belt slide table 27, a second synchronous belt slider 28, a second extension plate 29, and a second connecting plate 30. The second synchronous belt slide table 27 is fixed to the bottom of the platform 2, and the length direction of the second synchronous belt slide table 27 is the same as the width direction of the platform 2. The second synchronous belt slider 28 is slidably disposed on the second synchronous belt slide table 27. The second extension plate 29 is an L-shaped narrow plate, placed horizontally, with one end fixed to the second synchronous belt slide table 27 and the other end extending toward the transmission platform 3. The second connecting plate 30 is a rectangular long plate, arranged vertically and with its bottom end fixed to the second extension plate 29.

[0027] like Figure 4As shown, the clamping assembly specifically includes a positioning plate 23, two pairs of fixed clamping plates 24, a movable clamping plate 25, and a cylinder 26. The positioning plate 23 is fixed to the top of the connecting plate 30. The two fixed clamping plates 24 are symmetrically fixed to both ends of the positioning plate 23. The cylinder 26 is mounted on the fixed clamping plates 24, with the two cylinders 26 staggered. The output end of the cylinder 26 passes through the fixed clamping plate 24 and is fixed to the movable clamping plate 25. Therefore, driven by the synchronous belt slider 28, the clamping assembly will move closer to or away from the sewing fastening machine 8. The cylinder 26 can drive the movable clamping plate 25 closer to or away from the fixed clamping plate 24. When the elastic band is pulled out by the hook assembly, the synchronous belt slider 28 will drive the clamping assembly to move inward a certain distance, aligning the clamping assembly with the elastic band. The elastic band will be located between the fixed clamping plate 24 and the movable clamping plate 25. At this time, the cylinder 26 closest to the transmission table 3 starts first, driving the movable clamping plate 25. The elastic band is clamped by the fixed clamping plate 24 and then the pressing and cutting mechanism 5 is activated to press and cut the elastic band. After the pressing and cutting is completed, the synchronous belt slider 20 moves the hook assembly backward a short distance, so that the elastic band is pulled taut. At the same time, the pressing and cutting edge will move between the two fixed clamping plates 24. Then, another cylinder 26 is activated, so that the other moving clamping plate 25 also clamps the elastic band. Then, cylinder 17 is activated, so that the hook rod 15 moves outward to release the hook on the elastic band. Finally, the synchronous belt slider 28 drives the clamping assembly to move inward, so that the elastic band is moved to the sewing fastening machine 8. The sewing fastening machine 8 sews and fastens the pressing and cutting edge of the elastic band, completing the final production of the elastic band. Since the clamping assembly only needs to clamp the elastic band and does not need to flip it, the energy consumption of the equipment can be reduced, which has a certain energy-saving effect.
