However, the existing cloth rollers are usually fixed on the loom by means of bolts, gear drive devices, fixed seats, etc. Therefore, the replacement of the cloth roller requires the aid of special tools, the replacement steps are cumbersome and time-consuming, which not only increases the labor intensity of the staff, but also greatly reduces the production efficiency and the output of the fabric.
[0005] The technical problem to be solved by the utility model is achieved by adopting the following technical solutions: a take-up mechanism of a jet loom includes two drive boxes, a cloth roller, a front pressure roller, a lower pressure roller and a take-up roller are rotatably connected between the two drive boxes. Shaft heads are arranged at both ends of the cloth roller, round blocks are sleeved on both shaft heads, and clamping grooves for the round blocks to be inserted into are formed on the side walls of the two drive boxes. U-shaped grooves for the round blocks to roll into are formed on the inner walls of the top and bottom of the clamping grooves. Motors are arranged in both drive boxes, a first gear is fixed on each motor, a second gear meshing with the first gear is arranged on each shaft head, and a limiting structure for restricting the movement of the round blocks is arranged on both drive boxes.
[0006] By adopting the above technical solution, when it is necessary to replace the cloth winding roller during the actual use of the air-jet loom, first, the staff releases the limiting effect of the limiting structure on the round block. Subsequently, the staff moves the cloth winding roller in the direction away from the drive box. At the same time, both round blocks roll along the two U-shaped grooves in the direction away from the drive box until both round blocks are completely separated from the card slots, and then the disassembly of the cloth winding roller can be completed.
[0007] When it is necessary to install the cloth winding roller, first, the staff respectively sleeved the two round blocks on the two axles of the cloth winding roller to be installed on the air-jet loom. Subsequently, the staff moves the cloth winding roller in the direction close to the drive box, so that the two round blocks are respectively aligned with the two U-shaped grooves at the bottom.

Fixing blocks are arranged on the plurality of fixing rods. A groove for the fixing blocks to be snapped into is opened on one side of the U-shaped groove. The length of the fixing rod is greater than the length of the sliding groove.
[0011] By adopting the above technical solution, when fixing the first limiting plate with a fixed structure, the staff respectively snap two fixing rods into two sliding grooves, and then rotate the fixing rods so that the fixing blocks are snapped into the grooves.

[0012] The beneficial effects of the present utility model are as follows: When it is necessary to install the cloth winding roller, first, the staff respectively sleeved two round blocks on the two shaft heads of the cloth winding roller to be installed on the air-jet loom. Subsequently, the staff moved the cloth winding roller towards the direction close to the driving box, so that the two round blocks were respectively aligned with the two U-shaped grooves at the bottom. As the cloth winding roller continued to move, the two round blocks rolled in the U-shaped grooves at the bottom and top until the round blocks were completely snapped into the card slots. At the same time, the second gear meshed with the first gear. Then, the staff made the two round blocks unable to move in the U-shaped grooves at the bottom and top through the limiting structure, and thus the installation of the cloth winding roller was completed. Through this application, when the staff replaces the cloth winding roller, there is no need to rely on special tools, the replacement steps are simple, the time-consuming is short, the operation process is simple and labor-saving, which not only reduces the labor intensity of the staff, but also greatly improves the production efficiency and the output of fabrics.

[0019] In order to easily understand the technical means, creative features, achieved purposes and effects of the present utility model, the present utility model will be further described below in conjunction with specific illustrations.
[0020] As Figure 2 、 Figure 3 and Figure 5 shown, a take-up mechanism of a jet loom includes two drive boxes 1. A cloth winding roller 5, a front pressing roller 2, a lower pressing roller 3 and a take-up roller 4 are rotatably connected between the two drive boxes 1. Shaft heads 6 are provided at both ends of the cloth winding roller 5. Circular blocks 7 are sleeved on both shaft heads 6. Card slots 8 for the circular blocks 7 to be inserted are opened on the side walls of the two drive boxes 1. U-shaped grooves 9 for the circular blocks 7 to roll into are opened on the inner walls of the top and bottom of the card slots 8. Motors 20 are provided in both drive boxes 1. A first gear 14 is fixed on each motor 20. A second gear 17 meshing with the first gear 14 is provided on each shaft head 6. A limiting structure for restricting the movement of the circular blocks 7 is provided on both drive boxes 1.
[0021] During the actual use of the jet loom, when the cloth winding roller 5 needs to be replaced, first, the staff releases the limiting effect of the limiting structure on the circular block 7. Subsequently, the staff moves the cloth winding roller 5 in a direction away from the drive box 1. At the same time, both circular blocks 7 roll along the two U-shaped grooves 9 in a direction away from the drive box 1 until both circular blocks 7 are completely separated from the card slots 8, and then the disassembly of the cloth winding roller 5 can be completed.
[0022] When the cloth winding roller 5 needs to be installed, first, the staff sleeved the two circular blocks 7 on the two shaft heads 6 of the cloth winding roller 5 to be installed on the jet loom respectively. Subsequently, the staff moves the cloth winding roller 5 in a direction close to the drive box 1, so that the two circular blocks 7 are respectively aligned with the two bottom U-shaped grooves 9. As the cloth winding roller 5 continues to move, the two circular blocks 7 roll in the bottom and top U-shaped grooves 9 until the circular blocks 7 are completely inserted into the card slots 8. At the same time, the second gear 17 meshes with the first gear 14. Then, the staff makes the two circular blocks 7 unable to move in the U-shaped grooves 9 at the bottom and top through the limiting structure, and then the installation of the cloth winding roller 5 can be completed. Through this application, when the staff replaces the cloth winding roller 5, there is no need to use special tools, the replacement steps are simple, the time consumption is short, the operation process is simple and labor-saving, which not only reduces the labor intensity of the staff, but also greatly improves the production efficiency and the output of fabrics.
[0023] Among them, the setting of the U-shaped groove 9 not only serves as a guide for the circular block 7 to roll into the card slot 8, but also limits the circular block 7 in the horizontal direction, so that the circular block 7 is not easily separated from the card slot 8, so that the shaft heads 6 at both ends are connected to the two drive boxes 1 respectively, and further the cloth winding roller 5 is stably connected to the two drive boxes 1, and the operation is simple and convenient.
[0024] In addition, the socket connection of the circular block 7 enables, when replacing the fabric roll 5, simply removing the circular block 7 from the fabric roll 5 before replacement and socketing it onto the shaft head 6 of the fabric roll 5 to be installed. Since the circular block 7 can be used multiple times, there is no need to set a circular block 7 on each shaft head 6, reducing the consumables for manufacturing the circular block 7.
[0025] As Figure 3 and Figure 4 shown, the limiting structure includes a first limiting plate 18 slidably connected to the card slot 8 and a second limiting plate 19 fixed to the card slot 8. Semi-shaft holes 10 for the shaft head 6 to be inserted into are provided at opposite ends of the first limiting plate 18 and the second limiting plate 19. A sliding plate 21 for inserting into the U-shaped groove 9 is integrally formed on one side of the first limiting plate 18, and a handle 11 is provided on the first limiting plate 18.
[0026] When using the limiting structure to limit the circular block 7, first, the staff slides the first limiting plate 18 along the card slot 8 towards the second limiting plate 19 through the handle 11. At the same time, the sliding plate 21 slides along the top of one end of the U-shaped groove until one side of the opposite ends of the first limiting plate 18 and the second limiting plate 19 are in contact, and at the same time, the inner walls of the two shaft holes are in contact with the outer peripheral wall of the shaft head 6. Then, the circular block 7 can be limited by the limiting structure, so that the position of the circular block 7 does not move, and at the same time, the driving box 1 is closed to prevent dust from entering the driving box 1. The operation process is very simple.
[0027] As Figure 3 and Figure 4 shown, a fixing structure for fixing the first limiting plate 18 is provided in the U-shaped groove 9. The fixing structure includes a plurality of fixing rods 12. A sliding groove 13 for the plurality of fixing rods 12 to be inserted into is provided at one end of the U-shaped groove 9. Fixing blocks 15 are provided on the plurality of fixing rods 12. A groove 16 for the fixing blocks 15 to be inserted into is provided on one side of the U-shaped groove 9. The length of the fixing rod 12 is greater than the length of the sliding groove 13.
[0028] When using the fixing structure to fix the first limiting plate 18, the staff respectively inserts the two fixing rods 12 into the two sliding grooves 13, and then rotates the fixing rods 12 so that the fixing blocks 15 are inserted into the grooves 16. At the same time, the part of the fixing rod 12 higher than the sliding groove 13 abuts against the side of the first limiting plate 18. By the limitation of the sliding groove 13 on the fixing rod 12, the fixing rod 12 limits the first limiting plate 18, and thus the fixing of the first limiting plate 18 can be completed, making the first limiting plate 18 more firmly limit the circular block 7. The operation is simple and convenient.
