[0019] The technical solutions in the embodiments will be described clearly and completely below in combination with the drawings in the embodiments. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0020] As shown in Figure 1 , Figure 2 , Figure 3 The present embodiment discloses a setting machine cloth taking mechanism, which comprises a press wheel assembly 1, a cloth taking assembly 2, a conveying device 3 and a supporting roller 4. The conveying device 3 comprises a shell 33 and chain blocks 31 forming a conveying belt. The chain blocks 31 are provided with needle plates 32, and the upper end surface of the needle plates 32 is provided with a plurality of needles 321. The needle plates 32 can fix the edges of the fabric 5, and the edges of the fabric 5 are fixed on the chain blocks 31 by the needles 321 and conveyed. The chain blocks 31 and the needle plates 32 are the specific structures of the prior art, which will not be described here. The press wheel assembly 1 and the supporting roller 4 are fixedly installed on the upper end surface of the shell 33. The press wheel assembly 1 comprises a wool press wheel 11 and a motor 12. The motor 12 drives the wool press wheel 11 to rotate. The wool press wheel 11 comprises a wool wheel 111 and a rotating wheel 112. The wool wheel 111 is located above the needle plates 32, and the outer peripheral wall of the wool wheel 111 is provided with an annular wool brush. The needles 321 of the needle plates 32 can extend into the wool brush, so that the wool brush can press the fabric 5 against the upper end surface of the needle plates 32. The fabric 5 is fixed between the wool press wheel 11 and the needle plates 32. The conveying belt formed by the chain blocks 31 conveys the fabric 5 from the wool press wheel 11 to the supporting roller 4. After passing through the supporting roller 4, the fabric 5 is conveyed upward to the next fabric falling device.

[0021] Two conveying devices 3 are provided, spaced apart. Each conveying device 3 can fix the two sides of the fabric 5. Each conveying device 3 corresponds to a fabric picking assembly 2, located between the pressure roller 11 and the support roller 4. The fabric picking assembly 2 includes a base 22 and multiple picking wheels 21. The picking wheels 21 are rotatable and arranged along the conveying direction of the fabric 5. The picking wheels 21 are arranged from low to high from the pressure roller 11 to the support roller 4. The upper end of the picking wheel 21 at the highest position is higher than the upper end of the needle 321, ensuring that the fabric 5 is completely removed when it reaches the highest picking wheel 21. The upper end of the fabric picking wheel 21, located at the highest position away from the needle 321, is flush with the lower end of the support roller 4. The support roller 4 can tension the fabric 5 during delivery to prevent wrinkles. The fabric picking wheel 21 abuts against the lower end of the fabric 5. The fabric picking wheel 21 is arranged from low to high to support the lower end of the fabric 5 during the fabric 5 conveying process, so that the edge of the fabric 5 is gradually raised and the fabric 5 is gradually pushed upward from the needle 321. The fabric 5 can be removed from the needle relatively slowly and gently, which can eliminate the risk of damage when the fabric 5 is removed and remove the fabric 5 stably to prevent the fabric 5 from getting stuck.

[0022] More preferably, a fabric picking wheel 21 is provided below the pressure roller 11, and the rotating wheel 112 is located above the fabric picking wheel 21. The fabric picking wheel 21 located below the pressure roller 11 can play a supporting role in advance, supporting the part of the fabric 5 located outside the needle plate 32 before the fabric 5 comes into contact with the fabric picking wheels 21 distributed at different heights, so that the subsequent fabric picking wheel 21 can better pick up the edge of the fabric 5 from the needle plate 32.

[0023] The outer circumferential surface of the fabric picking wheel 21 is arc-shaped and contacts the lower surface of the fabric 5, which can increase the contact area between the fabric picking wheel 21 and the fabric 5. The fabric picking wheel 21 is provided with multiple protruding ridges 212, which are distributed in a ring around the outer circumferential surface of the fabric picking wheel 21. The protruding ridges 212 can increase the friction between the fabric picking wheel 21 and the fabric 5, so that the fabric picking wheel 21 can rotate with the fabric 5 and prevent sliding friction wear of the fabric 5 between the fabric picking wheel 21 and the fabric 5.

[0024] The base 22 is provided with multiple mounting seats 221. Each mounting seat 221 has a threaded channel 2211 and a sliding channel 2212. The cloth-picking wheel 21 is rotatably mounted on the connecting rod 211. The connecting rod 211 is at least partially installed in the sliding channel 2212 and can move along the sliding channel 2212. A threaded rod 23 is mounted on the mounting seat 221. The threaded rod 23 is at least partially located in the threaded channel 2211 and abuts against the connecting rod 211. The connecting rod 211 includes a retaining ring 2111. 2111 can move up and down along the sliding channel 2212. The top cover 25 is installed on the top of the mounting base 221. The spring 24 is installed inside the sliding channel 2212. One end of the spring 24 abuts against the retaining ring 2111, and the other end of the spring 24 abuts against the top cover 25. The rotation of the threaded rod 23 can drive the connecting rod 211 to move up and down, and can control and adjust the height of the fabric picking wheel 21. The final height of the fabric picking wheel 21 for picking up the fabric 5 can be adjusted according to the elasticity, tension and thickness of different fabrics 5. It is suitable for various fabrics 5.

[0025] The connecting rod 211 is provided with a limiting block 2112, and a limiting groove 2213 is opened on the side wall of the sliding channel 2212. The limiting block 2112 slides along the limiting groove 2213. The limiting block 2112 can restrict the connecting rod 211 from rotating in the sliding channel 2212, thus limiting the rotation direction of the connecting rod 211.

[0026] More preferably, the upper end face of the threaded rod 23 is an arc-shaped protrusion, and the lower end face of the connecting rod 211 is an arc-shaped protrusion. The upper end face of the threaded rod 23 abuts against the lower end face of the connecting rod 211, and the two arc-shaped protrusions contact each other, so as to minimize the contact area between the connecting rod 211 and the threaded rod 23 and reduce the friction between them.

[0027] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
