[0022] To make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] Refer to Figure 1 , Figure 2 As shown, a single-motor drive device for the needle receiving position includes a tablet pressing unit 1, a needle turning triangle 2, and a mountain plate 3. The tablet pressing unit 1 is arranged on the mountain plate 3, the needle turning triangle 2 is telescopically arranged above the tablet pressing unit 1, and a rotary drive device 4 is fixedly installed on the back of the mountain plate 3 for driving the tablet pressing unit 1 and the needle turning triangle 2 to work synchronously. In this embodiment, the rotary drive device 4 preferably uses a servo motor.

[0024] Refer to Figure 3 , Figure 4 As shown, among them, the tablet pressing unit 1 includes a first needle receiving tablet 11 and a second needle receiving tablet 12. The first needle receiving tablet 11 and the second needle receiving tablet 12 are sequentially telescopically arranged on the mountain plate, and a tablet pressing push plate 14 is arranged between the first needle receiving tablet 11 and the second needle receiving tablet 12. Tablet pressing bottom plates 15 are respectively arranged on both sides of the rotary drive device 4, a tablet pressing cover plate 16 is covered on the tablet pressing bottom plates 15, first sliding grooves 161 are penetrated through both ends of the tablet pressing cover plate 16, and the tablet pressing push plate 14 is slidably inserted into the first sliding grooves 161, and second sliding grooves 162 are penetrated through the front and rear ends of the tablet pressing cover plate 16 to enable the first needle receiving tablet 11 and the second needle receiving tablet 12 to be slidably inserted into the second sliding grooves 162.

[0025] Combined with Figure 7As shown, further, first push grooves 141 and second push grooves 142 are respectively arranged at two ends of the tablet pressing push plate 14. Rollers are fixedly arranged at the bottoms of the first pin connecting tablet 11 and the second pin connecting tablet 12, and are respectively in sliding fit with the first push grooves 141 and the second push grooves 142. In this embodiment, a gear 41 is fixedly installed on the output shaft of the rotary driving device 4. One side of the tablet pressing push plate 14 has teeth meshing with the gear 41, so as to drive the tablet pressing push plate 14 to move left and right along the first sliding groove 161 through the rotary driving device 4, so that the first pin connecting tablet 11 and the second pin connecting tablet 12 perform telescopic movement under the action of the first push grooves 141 and the second push grooves 142.

[0026] Preferably, the height of one end of the first push groove 141 is greater than the height of the second push groove 142, and the height of the other end of the first push groove 141 is lower than the height of the second push groove 142, so that when the tablet pressing push plate 14 moves left or right, the extending strokes between the first pin connecting tablet 11 and the second pin connecting tablet 12 are different.

[0027] Specifically, the first push groove 141 includes a first horizontal portion 1411, a second horizontal portion 1412, a first arc portion 1413, and a second arc portion 1414. The first arc portion 1413 is arranged between the first horizontal portion 1411 and the second arc portion 1414, and an "S" shape is formed between the first arc portion 1413 and the second arc portion 1414. The second horizontal portion 1412 is arranged at the right end of the second arc portion 1414, and the height of the second horizontal portion 1412 is lower than that of the first horizontal portion 1411.

[0028] The second push groove 142 includes a third horizontal portion 1421, a fourth horizontal portion 1422, and a third arc portion 1423. The third arc portion 1423 is arranged between the third horizontal portion 1421 and the fourth horizontal portion 1422. The height of the fourth horizontal portion is the same as that of the first horizontal portion 1411, and the height of the third horizontal portion 1421 is lower than that of the fourth horizontal portion 1422.

[0029] Refer to Figures 4 - 7As shown, through the above settings, when the random head of the mountain plate 3 moves to the left, the rotary drive device 4 drives the pressing plate push plate 14 to move to the right, so that the roller on the first needle-connecting pressing plate 11 moves from the second arc portion 1414 to the second horizontal portion 1412, while the roller on the second needle-connecting pressing plate 12 moves from the third arc portion 1423 to the fourth horizontal portion 1422. Thus, the first needle-connecting pressing plate 11 and the second needle-connecting pressing plate 12 are linked to extend out of the mountain plate. And because the height of the second horizontal portion 1412 is lower than that of the fourth horizontal portion 1422, the extending distance of the second needle-connecting pressing plate 12 is greater than that of the first needle-connecting pressing plate 11, so that the long needle feet on the needle plate are completely sunk into the needle grooves under the action of the first needle-connecting pressing plate 11, while the long needle feet are not completely sunk into the needle grooves under the action of the second needle-connecting pressing plate 12, and part of the heel of the long needle feet still protrudes. In this way, the specified actions are completed in cooperation with the mountain plate.

[0030] When the random head of the mountain plate 3 moves to the right, the rotary drive device 4 drives the pressing plate push plate 14 to move to the left, so that the roller on the first needle-connecting pressing plate 11 moves from the second arc portion 1414 to the first horizontal portion 1411, while the roller on the second needle-connecting pressing plate 12 moves from the third arc portion 1423 to the third horizontal portion 1421. Thus, the first needle-connecting pressing plate 11 and the second needle-connecting pressing plate 12 are linked to extend out of the mountain plate 3. And because the height of the first horizontal portion 1412 is higher than that of the fourth horizontal portion 1422, the extending distance of the first needle-connecting pressing plate 11 is greater than that of the second needle-connecting pressing plate 12, so that the long needle feet on the needle plate are completely sunk into the needle grooves under the action of the second needle-connecting pressing plate 12, while the long needle feet are not completely sunk into the needle grooves under the action of the first needle-connecting pressing plate 11, and part of the heel of the long needle feet still protrudes. In this way, the specified actions are completed in cooperation with the mountain plate.

[0031] During reset, the rotary drive device 4 is used to drive the pressing plate push plate 14 to reset, so that the roller of the first needle-connecting pressing plate 11 moves to the second arc portion 1413, and the roller of the second needle-connecting pressing plate 12 moves to the third arc portion 1423. Thus, the first needle-connecting pressing plate 11 and the second needle-connecting pressing plate are linked to retract into the mountain plate 3, so that the first needle-connecting pressing plate 11 and the second needle-connecting pressing plate do not participate in pressing the long needle feet on the needle plate.

[0032] Refer to Figure 3 、 Figure 8 As shown, further, a linkage mechanism 5 is provided between the rotary drive device 4 and the needle-flipping triangle 2. The linkage mechanism 5 includes a cam 51 and a swing rod 52. The cam 51 is arranged on the output shaft of the rotary drive device 4. The middle part of the swing rod 52 is pivotally connected to the back of the mountain plate 3. One end of the swing rod 52 is in contact and cooperation with the outer contour of the cam 51. And a shaft rod 21 is arranged on the back of the needle-flipping triangle 2. The bottom surface of the shaft rod 21 has a slot 211 for cooperating with the end of the swing rod 52. The other end of the swing rod 52 is in contact and cooperation with the shaft rod 21 of the needle-flipping triangle 2.

[0033] Among them, the outer periphery of the cam 51 is relatively provided with a first protrusion 511 and a second protrusion 512, so that the rocker 52 can link the needle turning cam 2 to telescopic movement under the push of the first protrusion 511 or the second protrusion 512, thereby cooperating with the pressing unit to complete the specified weaving action.

[0034] Of course, the above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. Any modifications made according to the spirit of the main technical scheme of the utility model should be included in the protection scope of the utility model.
