Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] Reference Figures 1-5 According to an embodiment of the present invention, a ring-shaped elastic band production equipment includes a feeding assembly, a cutting assembly, a flipping assembly, and a welding assembly.

[0022] The feeding component is used to deliver fabric such as elastic bands into the flipping component. Specifically, for example... Figure 1 and Figure 3 As shown, the feeding assembly includes a feeding platform 11, and a groove 12 is provided on the upper side of the feeding platform 11. The feeding platform 11 is also provided with a feeding wheel 13 driven to rotate by a feeding motor 14. The rolled elastic band can be unwound and loaded into the groove 12 through the right end of the feeding platform 11. If the feeding wheel 13 rotates under the drive of the feeding motor 14, the elastic band sandwiched between the feeding wheel 13 and the bottom surface of the groove 12 will be delivered to the left.

[0023] In addition, the feeding assembly also includes a first linear module 21 located on the left side of the feeding table 11. The first linear module 21 has a first slider 22 that can move laterally and is equipped with a gripper device facing the feeding table 11. After the gripper device clamps the left end of the elastic band that extends to the left side of the feeding table 11, the first slider 22 can move to the left to load the elastic band into the flipping assembly.

[0024] The cutting component is used to separate the elastic band clamped in the flipping component from the elastic band located in the slide groove 12, such as Figure 3 As shown, the cutting assembly specifically includes a receiving plate 31 mounted on the left end of the feeding table 11, a mounting platform 32 fixed on one side of the receiving plate 31, and a blade holder 33 hinged in the mounting platform 32. The blade holder 33 contains a cutting blade, and also includes a control device for controlling the movement of the blade holder 33.

[0025] The flipping component is used to flip the cut elastic band to form a loop with the ends joined together, specifically, as follows: Figure 2-4As shown, the flipping assembly includes a second linear module 41 fixed to the lower side of the feeding table 11. A mounting plate 42 is mounted on a second slider that can move back and forth inside the second linear module 41. Two flipping motors 43 distributed on the left and right are mounted on the front side of the mounting plate 42. The output shaft of the flipping motor 43 extends to the rear side of the mounting plate 42 and is mounted on a mounting frame 44. A first clamping cylinder 45 is fixed on the mounting frame 44, and an upper clamping plate 46 is fixed at the rear end of the mounting frame 44. A lower clamping plate 47 is fixed at the lower end of the piston rod inside the first clamping cylinder 45. After the first clamping cylinder 45 controls the first upper clamping plate 46 and the first lower clamping plate 47 to clamp together and the elastic band is cut off, the flipping motor 43 controls the mounting bracket 44 to flip half a turn (the two mounting brackets 44 on the left and right rotate in opposite directions) so that the two ends of the elastic band can come closer together. Then, the second linear module 41 can control the second slider to move backward, so that the two ends of the elastic band are delivered into the welding assembly for welding.

[0026] The welding assembly includes a machine base 51, and the machine base 51 is equipped with an ultrasonic welding head 52 that can be raised and lowered.

[0027] Furthermore, the ultrasonic welding head 52 extends to the front of the machine base 51, and the front of the machine base 51 is provided with a receiving platform 53 facing the ultrasonic welding head 52.

[0028] It should be noted that the lifting control method and welding principle of the ultrasonic welding head 52 are conventional solutions in the prior art, and will not be described in detail here.

[0029] When the second linear module 41 controls the second slider to move backward, the left and right sets of the first upper clamping plate 46 and the first lower clamping plate 47 can be positioned on the left and right sides of the receiving platform 53 (e.g., Figure 5 (as shown in the diagram), and both ends of the elastic band are delivered to the receiving platform 53, after which the ultrasonic welding head 52 can move down and perform welding work on the two ends of the elastic band in the stacked state.

[0030] To further improve the level of automation, a material unloading assembly is also included. The material unloading assembly includes a straight plate that is slidably connected to the machine base 51. The front end of the straight plate is equipped with a laterally extending pusher plate 54, and the machine base 51 is equipped with a pusher cylinder 55 for controlling the front and rear position of the straight plate. The front and rear stroke of the straight plate is not less than the front and rear width of the pusher plate 54.

[0031] During the welding process, the second linear module 41 can control the second slider to move forward and reset. After the welding is completed and the ultrasonic welding head 52 moves upward and resets, the pusher cylinder 55 can control the straight plate and the pusher plate 54 to move forward to push out the elastic band that is looped around the receiving platform 53, so as to realize the material removal function.

[0032] The tool holder 33 can be directly driven to rotate by a cylinder, but in this embodiment, due to space constraints, such as Figure 3 As shown, the control device includes a lifting block 34 that is slidably connected to the left end of the feeding table 11. The lifting block 34 is connected to the rear edge of the lower side of the blade holder 33 by a rope. The second linear module 41 is also equipped with a cutting cylinder 35 for controlling the up and down movement of the lifting block 34. A spring is installed between the receiving plate 31 and the blade holder 33 for resetting. The cutting cylinder 35 can control the lifting block 34 to move down and pull the blade holder 33 down through the rope until the cutting blade is inserted into the receiving plate 31 to complete the cutting of the elastic band. After the lifting block 34 moves up and resets, the blade holder 33 can swing up and reset under the action of the spring to avoid interfering with the elastic band being pushed out of the slide groove 12.

[0033] Furthermore, the first upper clamping plate 46 and the first lower clamping plate 47 are mounted on the side of the two mounting brackets 44 that are far apart from each other (in the upright state), so that the two ends of the elastic band can be closer together after the mounting brackets 44 are flipped, thus avoiding welding failure later.

[0034] The gripper device includes a gripper seat fixed to the first slider 22, a second lower clamping plate 23 fixed on the gripper seat, and a second clamping cylinder 24 also provided on the gripper seat. The lower end of the piston rod in the second clamping cylinder 24 is equipped with a second upper clamping plate 25. The second clamping cylinder 24 can control whether the second upper clamping plate 25 is attached to the second lower clamping plate 23, thereby controlling whether to perform clamping work.

[0035] The second lower clamping plate 23 and the second upper clamping plate 25 extend to the right and then bend forward to form an "L" shape. The lateral extension portion inside the second upper clamping plate 25 is provided with an inclined portion that tilts to the right and downward to improve clamping stability.

[0036] In addition, two positioning plates 26 are provided in the chute 12, which are distributed front and back. The positioning plates 26 are respectively attached to the front and back sides of the chute 12. The elastic band will be conveyed between the positioning plates 26 to avoid front and back tilting. The positioning plates 26 can be replaced with different specifications so that the ring elastic band production equipment can perform transmission and welding work on elastic bands of different specifications.

[0037] In summary, the specific processing flow is as follows: The feeding wheel 13 feeds the left end of the elastic band to the left side of the feeding table 11 and then stops rotating. Then the first slider 22 moves to the right, so that the second lower clamping plate 23 and the second upper clamping plate 25 clamp the left end of the elastic band (passing between the first upper clamping plate 46 and the first lower clamping plate 47). Then the first slider 22 moves to the left, so that the elastic band is between the two sets of the first upper clamping plate 46 and the first lower clamping plate 47 on the left and right sides.

[0038] Then, the first upper clamping plate 46 and the first lower clamping plate 47, which are mounted on the mounting bracket 44 on the left, are clamped together. At this time, the feeding wheel 13 can continue to rotate for a certain period of time so that the elastic band hangs down between the two sets of the first upper clamping plate 46 and the first lower clamping plate 47 on the left and right sides in a U-shape.

[0039] After the desired length is reached, the first upper clamping plate 46 and the first lower clamping plate 47 on the right side clamp the elastic band, and then the cutter holder 33 drops to cut the elastic band.

[0040] Then, the two mounting brackets 44 are rotated half a turn under the control of the flipping motor 43 so that the two ends of the cut elastic band are close to each other and stacked up and down (the mounting bracket 44 on the left rotates clockwise and the mounting bracket 44 on the right rotates counterclockwise), at which point the cut elastic band portion forms a loop.

[0041] Then, the second linear module 41 controls the mounting plate 42 to move backward so that the looped elastic band is fitted over the receiving platform 53, and then the ultrasonic welding head 52 can move down to perform welding work.

[0042] During the welding process, the mounting plate 42 can move forward to reset for the next cycle of work, and after welding is completed, the pusher plate 54 can move forward to push out the welded and looped elastic band.

[0043] It should be noted that the left and right mounting brackets 44 have different rotation speeds, but ultimately reach the same angle, so that the elastic bands can be stacked smoothly up and down. The front side of the receiving platform 53 can be provided with a slope to prevent the elastic band from tilting when it is transferred to the receiving platform 53. The first linear module 21 and the feeding table 11 can be supported by legs (not shown in the figure), or the first linear module 21 and the feeding table 11 can be fixed on the machine base 51 to increase the overall integrity. The first linear module and the second linear module are driven by a lead screw and a drive motor to move the slider inside them, which is a conventional solution in the prior art and will not be described in detail here. The curved surface of the feeding wheel 13 can be fitted with rubber strips, or the curved surface of the feeding wheel 13 can be covered with a rubber layer to increase friction and prevent relative sliding with the elastic band.

[0044] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
