[0028] The preferred embodiments of the present invention are described in detail with reference to the accompanying drawings.

[0029] Figures 1 to 11 , which is a preferred embodiment of a twist needle waist device provided by the present invention. Figures 1 to 11As shown, the twist needle waist-drumming device includes a workbench 10, on which is provided a vibrating disk feeding mechanism 20 for feeding twist needles 100, a receiving mechanism 30 docked with a discharge port 21 of the vibrating disk feeding mechanism 20 for receiving twist needles, a drumming mechanism 40 for drumming the received twist needles, and a pushing mechanism 50 for pushing the twist needles received by the receiving mechanism 30 into the drumming mechanism 40. In this way, when the vibrating disk feeding mechanism 20 vibrates the twist needles 100 to the discharge port 21, the receiving mechanism 30 docks with the discharge port, and the twist needles in the discharge port enter the receiving mechanism 30, and then the pushing mechanism 50 pushes the twist needles 100 in the receiving mechanism 30 into the drumming mechanism 40 for drumming.

[0030] like Figures 7 to 10 As shown, the waist-bulging mechanism 40 includes a first receiving block 41, a first driver 42 for driving the first receiving block to slide, a second receiving block 43 for docking with the first receiving block 41 to form a bulged waist, and a second driver 44 for driving the second receiving block to slide. The first receiving block 41 is provided with a first receiving groove 411 for accommodating one end of the twist needle when the pushing mechanism 50 pushes the twist needle, and the second receiving block 43 is provided with a second receiving groove 431 for accommodating the other end of the twist needle when the two receiving blocks are docked. The sum of the lengths of the two receiving grooves 411 and 431 is less than the length of the un-bulged twist needle 100. In this way, under the action of the first driver 42 and the second driver 44, the first receiving block 41 is docked with the second receiving block 43, and the first receiving groove 411 is docked with the second receiving groove 431, thereby squeezing the twist needle placed in the receiving groove 411, so that the twist needle forms a bulged waist.

[0031] One end of the first receiving groove 411 forms a first waist hole 4111, and the other end of the first receiving groove 411 is a sealed end; the first waist hole 4111 is a conical hole, one end of which is large and the other end is small; the other end of the second receiving groove 431 forms a second waist hole 4311 for docking with the first waist hole when the two receiving blocks are docked, and one end of the second receiving groove 431 is a sealed end; the second waist hole 4311 is a conical hole, one end of which is large and the other end is small; when the two receiving blocks are docked, the larger ends of the two waist holes are docked, and the first waist hole 4111 is docked with the second waist hole 4311 to form a complete waist hole, and the twist needle 100 is also completed in the complete waist hole to form a waist twist needle 200.

[0032] like Fig.10As shown, the waist-drumming mechanism also includes a fixed seat 45 fixedly arranged on the workbench 10, and a first slide groove 451 for the first receiving block 41 to slide and a second slide groove 452 for the second receiving block to slide are provided on the fixed seat 45, the first slide groove 451 and the second slide groove 452 are horizontally and vertically, and an intersection 453 for the first receiving block 41 and the second receiving block 43 to dock is formed between the first slide groove and the second slide groove. When the first receiving groove 411 of the first receiving block 41 receives one end of the twist needle, the first driver 42 drives the first receiving block 41 to slide along the first slide groove 451 to the intersection 453, and the second driver 44 drives the second receiving block 43 to slide along the second slide groove 452 to the intersection 453, and the second receiving groove 431 receives the other end of the twist needle, and the first receiving block 41 and the second receiving block 43 dock in the intersection 453 to squeeze the twist needle to form a waist-drumming twist needle.

[0033] The fixed seat 45 is provided with a first pressing plate 46 which is located on the first slide groove to prevent the first receiving block in the first slide groove from jumping, and a second pressing plate 47 which is located on the second slide groove to prevent the second receiving block in the second slide groove from jumping, so as to ensure that the receiving block slides smoothly in the slide groove and prevent the twist needle in the receiving block from falling.

[0034] like Figure 5 As shown, the material receiving mechanism 30 includes a material receiving seat 31 for receiving twist needles, a material receiving slide 32 connected to the material receiving seat 31 for driving the material receiving seat up and down, and a material receiving driver 33 for driving the material receiving slide 32 to rise and fall. The material receiving seat 31 is provided with a material receiving groove 311 for receiving the twist needles transmitted by the vibration disk feeding mechanism. When receiving materials, the material receiving driver 33 drives the material receiving slide 32 to move downward, and the material receiving slide 32 drives the material receiving seat 31 to descend to a preset position and dock with the discharge port 21 of the vibration disk feeding mechanism 20; after receiving the twist needles, the material receiving driver 33 drives the material receiving slide 32 to move upward, and the material receiving slide 32 drives the material receiving seat 31 to rise to a preset position, and the material receiving seat 31 is aligned with the pushing mechanism 50, so that the pushing mechanism 50 can push the twist needles 100 in the material receiving seat 31 into the first receiving groove 411 of the first receiving block 41.

[0035] like Figure 6 As shown, the pushing mechanism 50 includes a pushing block 51 for pushing the twist needle in the material receiving mechanism into the first receiving groove and a pushing block driver 52 for driving the pushing block to move. After the material receiving seat 31 receives the twist needle 100, it rises to a preset position, and the pushing block driver 52 drives the pushing block 51 to push the twist needle 100 in the material receiving seat 31 to move, so that the twist needle 100 moves to the first receiving groove 411 of the first receiving block 41, and one end of the twist needle 100 is accommodated in the first receiving groove 411. Due to the large area of ​​the pushing block 51, the pushing block 51 can contact one end of the twist needle 100 when pushing, so as to stably push the twist needle and avoid misalignment with the twist needle.

[0036] The end of the push block close to the first receiving groove forms an opening 511 for the twist needle to be inserted into and pressed. In this way, when the twist needle is pushed, one end of the twist needle 100 is inserted into the opening 511 to prevent the twist needle from jumping during the pushing process, and ensure that the twist needle 100 is accurately pushed into the first receiving groove 411. In order to ensure stable pushing of the twist needle, the bottom side of the push block 51 is also formed with a push shaft 512 for pushing the twist needle. When the twist needle is pushed, the push shaft 512 is inserted into the material receiving groove 311 of the material receiving seat 31 to steadily push the twist needle 100.

[0037] The twist needle waist drumming device also includes a clamping mechanism 60 for clamping the waist drum twist needles from the waist drumming mechanism, a blanking port 70 is provided on the workbench 10 for the waist drum twist needles clamped by the clamping mechanism to be dropped, and a receiving box 80 is provided below the blanking port for receiving the waist drum twist needles dropped from the blanking port, so that after the waist drumming is completed, the second receiving block 43 is separated from the first receiving block 41 under the action of the second driver 44, and the clamping mechanism 60 clamps the waist drum twist needles 200 on the first receiving block 41 or the second receiving block 43, and moves to the top of the blanking port 70 for blanking, and the waist drum twist needles 200 coming out of the blanking port 70 are collected by the receiving box 80.

[0038] like Fig.11 As shown, the clamping mechanism 60 includes a frame 61 fixed on the workbench 10, a material picking clamp 62 located between the first receiving block and the second receiving block, and a translation drive component 63 arranged on the frame for driving the material picking clamp 62 to move back and forth between the first receiving block 41 and the second receiving block 43 separated after the drum waist is completed to clamp the drum waist twisted needle. When the material picking clamp 62 is ready to clamp the drum waist twisted needle 200, the translation drive component 63 drives the material picking clamp 62 to move back and forth between the separated first receiving block 41 and the second receiving block 43 to clamp the drum waist twisted needle 200. After clamping the drum waist twisted needle 200, the translation drive component 63 drives the material picking clamp 62 to above the blanking port 70 for blanking. It is worth noting that when the first receiving block 41 and the second receiving block 43 are docked, the two clamping arms of the material taking clamp 62 remain open, which does not affect the docking of the first receiving block 41 and the second receiving block 43; and after the first receiving block 41 and the second receiving block 43 are separated, the material taking clamp 62 clamps the drum waist twist needle. Since the drum waist twist needle 200 is very small, after the two receiving blocks are separated, it is uncertain in which receiving block the drum waist twist needle 200 is located, so the material taking clamp 62 needs to move between the two receiving blocks to clamp the drum waist twist needle 200.

[0039] The translation drive assembly 63 includes a slide rail 631 arranged on the frame 61, a supporting seat 632 for supporting the material picking clamp 62, a translation slide 633 arranged on the supporting seat 632 and cooperating with the slide rail 631, and a slide driver 634 for driving the translation slide to move along the slide rail. When translating, the slide driver 634 drives the translation slide 633 to move along the slide rail 631, driving the material picking clamp 62 on the supporting seat 632 to move, so that the material picking clamp 62 moves back and forth between the two receiving seats to clamp the drum waist twist needle 200.

[0040] It is worth noting that in order to match the height of the vibration plate in the vibration plate feeding mechanism 20 and facilitate the receiving box 80 to receive materials, the material receiving mechanism 30, the material pushing mechanism 50 and the fixed seat 45 are all fixed on the workbench through a support seat; in addition, before the material pushing mechanism 50 pushes the material, a sensor is used to detect whether the material receiving mechanism 30 has received the material.

[0041] The specific working process of the whole twist needle waist device is as follows: 1) Figure 1 As shown, the vibrating plate feeding mechanism 20 vibrates the twist needle 100 to the discharge port 21, the receiving drive 33 drives the receiving slide 32 to move downward, and the receiving slide 32 drives the receiving seat 31 to descend to a preset position and dock with the discharge port 21 of the vibrating plate feeding mechanism 20; after receiving the twist needle, the receiving drive 33 drives the receiving slide 32 to move upward, and the receiving slide 32 drives the receiving seat 31 to rise to a preset position, and the receiving seat 31 is aligned with the pushing mechanism 50; 2) As shown in FIG. Figure 2 As shown, the push block driver 52 drives the push block 51 to move toward the material receiving seat 31, one end of the twist needle 100 extends into the opening 511, and the push shaft 412 extends into the material receiving groove 311 of the material receiving seat 31, pushing one end of the twist needle 100 to extend into the first receiving groove 411 of the first receiving block 41; 3) As shown Figure 3 , Figure 8 and Fig.11As shown, when the first receiving slot 411 of the first receiving block 41 receives one end of the twist needle, the first driver 42 drives the first receiving block 41 to slide along the first slide slot 451 to the intersection 453, and the second driver 44 drives the second receiving block 43 to slide along the second slide slot 452 to the intersection 453, and the second receiving slot 431 receives the other end of the twist needle, and the first receiving block 41 and the second receiving block 43 are docked in the intersection 453 to squeeze the twist needle to form a bulging twist needle; 4) After the bulging is completed, the second driver 44 drives the second receiving block 43 to slide along the second slide groove 452 to return to its original position, and the first receiving block 41 is separated from the second receiving block 43; 5) The slide driver 634 drives the translation slide 633 to move along the slide rail 631, driving the material picking clamp 62 on the supporting seat 632 to move, so that the material picking clamp 62 moves back and forth between the two receiving seats to clamp the drum waist twist needle 200; 6) After the material picking clamp 62 clamps the drum waist twist needle 200, the material picking clamp 62 is moved to above the blanking port 70, and the material is dropped from the blanking port 70 into the receiving box 80.
