A rotating shaft 3 is also rotatably provided on the bracket 1, and the rotating shaft 3 is located below the cloth roll 2. A swing rod 4 is fixedly installed on the rotating shaft 3, and the swing rod 4 is arranged along the radial direction of the rotating shaft 3. The number of the swing rods 4 is at least two, and a plurality of swing rods 4 are arranged in parallel at intervals, and the pressure shaft 5 is fixedly installed on the same end of the plurality of swing rods 4. A gravity block 41 is installed at the other end of the swing rod 4. Through the arrangement of the gravity block 41, the swing rod 4 can drive the pressure shaft 5 to rotate in the direction close to the cloth roll 2, so that the pressure wheel 51 is always attached to the outside of the cloth roll 2. On the one hand, the cloth roll 2 can always maintain a tension, and at the same time, the inertia of the cloth roll 2 during the rotation process can be offset. When the pulling of the cloth is stopped or the speed is reduced in the subsequent sequence, the rotation of the cloth roll 2 can be stopped in time and the rotation speed of the cloth roll 2 can be reduced, so as to avoid excessive release of the cloth and affect the neatness of the cloth.

[0023] Specifically, in this embodiment, the pressing wheel 51 is made of polyurethane material to prevent the pressing wheel 51 from causing damage to the fabric.

[0024] In some embodiments, the gravity block 41 may be implemented as follows: Figure 1 , Figure 2 See also Figure 1 , Figure 2 , a mounting plate 42 is fixedly mounted on the swing rod 4, a pull rod 43 is fixedly mounted on the mounting plate 42 and is spaced and parallel to the swing rod 4, a through hole for mounting the pull rod 43 is provided on the weight block 41, and a fixing piece 44 for fixing the weight block 41 to the mounting plate 42 is threadedly connected on the pull rod 43. A mounting plate 42 is fixedly mounted on the swing rod 4, and the end of the swing rod 4 is located on the side of the mounting plate 42 away from the pressure shaft 5, and a plurality of weight blocks 41 are mounted on the swing rod 4. The plurality of weight blocks 41 are all mounted on the swing rod 4, and a through hole for inserting the pull rod 43 is provided on the weight block 41. The number of the pull rods 43 is multiple, and the stability of the installation of the weight blocks 41 can be ensured. By setting the pull rod 43, the number of the weight blocks 41 can be changed according to the on-site requirements, so as to adjust the pressure of the pressing wheel 51 on the cloth roll 2. While ensuring the stable output of the cloth, the cloth roll 2 can be pressed by movement.

[0025] Specifically, in this embodiment, when installing the gravity block 41 , the gravity block 41 is mounted on the swing rod 4 and the pull rod 43 , and then the fixing member 44 is used to press the gravity block 41 onto the mounting plate 42 .

[0026] In some embodiments, the rotating shaft 3 may be Figure 3 See the structure shown. Figure 3 A limiting rod 31 is fixedly mounted on the rotating shaft 3 and arranged along the radial direction of the rotating shaft 3. A stopper 32 is fixedly mounted on the bracket 1 and used to limit the swing of the limiting rod 31. The limiting rod 31 can abut against the stopper 32. The limiting rod 31 is arranged along the radial direction of the rotating shaft 3. When the rotating shaft 3 rotates on the bracket 1, the limiting rod 31 can abut against the stopper 32 to limit the rotating shaft 3 from continuing to rotate.

[0027] Specifically, in this embodiment, when the limit rod 31 abuts against the stop rod 32, the swing rod 4 is tilted in the vertical direction to prevent the swing rod 4 from rotating to a vertical state. When placing the cloth roll 2, the pressure wheel 51 on the pressure shaft 5 is located on one side of the cloth roll 2 to prevent the pressure wheel 51 from affecting the placement of the cloth roll 2 when the cloth roll 2 is placed.

[0028] In some embodiments, the blocking rod 32 may be Figure 3 See the structure shown. Figure 3, the baffle rod 32 is located directly below the rotating shaft 3, and the position of the baffle rod 32 on the bracket 1 has the freedom to be adjusted in the vertical direction. The baffle rod 32 is installed on the inner side of the bracket 1, and a screw rod for penetrating the bracket 1 is provided at one end of the baffle rod 32, a nut is threadedly connected to the screw rod, a through groove arranged in the vertical direction is provided on the bracket 1, and the screw rod at the end of the baffle rod 32 is located inside the through groove. The baffle rod 32 can be fixedly installed on the bracket 1 by the nut. By adjusting the height of the baffle rod 32, the swing angle of the rocker arm 4 can be adjusted according to the outer diameter of the central axis inside the fabric roll 2. The pressure wheel 51 on the pressure shaft 5 can be effectively pressed against the outer side of the fabric roll 2.

[0029] In some embodiments, the bracket 1 can be used as follows Figure 1 , Figure 3 See also Figure 1 , Figure 3 The bracket 1 is also hingedly provided with a swing frame 6, the hinge axis of the swing frame 6 is coaxially arranged with the rotating shaft 3, and the swing frame 6 is provided with a positioning plate 61 for abutting against the outer side of the pressure wheel 51, and a driving member 7 for pushing the swing frame 6 to rotate in a direction close to the pressure shaft 5 is also provided between the bracket 1 and the swing frame 6. The two ends of the rotating shaft 3 extend out of the outer side of the bracket 1. The swing frame 6 is provided with two connecting rods respectively rotatably arranged at the two ends of the rotating shaft 3, and the swing frame 6 is hingedly arranged on the bracket 1 through the connecting rods. A plurality of positioning plates 61 are arranged at intervals along the length direction of the rotating shaft 3 on the swing frame 6, and the positions and numbers of the positioning plates 61 correspond to the pressure wheel 51 one by one. When the swing frame 6 swings upward, on the one hand, the positioning plate 61 can drive the pressure wheel 51 to press against the outer side of the cloth roll 2. At the same time, the positioning plate 61 is attached to the outer side of the pressure wheel 51, which can prevent the pressure wheel 51 from rotating on the pressure shaft 5. The fabric roll 2 can be fixed on the bracket 1 by the friction force between the pressing wheel 51 and the fabric, and can play a certain fixing role on the fabric roll 2 when the production is stopped in the subsequent sequence.

[0030] In some embodiments, the driving member 7 may be Figure 3 See the structure shown. Figure 3 The fixed end of the driving member 7 is hingedly set on the bracket 1, and the driving end of the driving member 7 is hingedly set on the swing frame 6. The driving member 7 is a cylinder, and the fixed end of the driving member 7 is hingedly set on the bracket 1, and the driving end of the driving member 7 is hingedly set on the swing frame 6. There are two driving members 7, and the two driving members 7 are respectively located at both ends of the swing frame 6. By starting the driving member 7, the swing frame 6 can be driven to swing, so that the positioning plate 61 abuts against the outer side of the pressure wheel 51.

[0031] In some embodiments, the positioning plate 61 may be Figure 3 See the structure shown. Figure 3The positioning plate 61 is an arc-shaped structure that matches the outer shape of the pressing wheel 51. The positioning plate 61 is an arc-shaped structure. When the positioning plate 61 abuts against the outer side of the pressing wheel 51, the inner side of the positioning plate 61 is pressed against the outer side of the pressing wheel 51. Increasing the contact area between the positioning plate 61 and the pressing wheel 51 can effectively limit the rotation of the pressing wheel 51.

[0032] In some embodiments, the positioning plate 61 may be Figure 3 See the structure shown. Figure 3 A buffer pad 611 is installed on the inner side of the positioning plate 61 for abutting against the pressing wheel 51. The buffer pad 611 is a polyurethane gasket, and the buffer pad 611 is fixedly installed on the inner side of the positioning plate 61. The setting of the buffer pad 611 can, on the one hand, prevent the positioning plate 61 from being damaged by the collision between the positioning plate 61 and the pressing wheel 51 when the positioning plate 61 is close to the pressing wheel 51. At the same time, the friction between the positioning plate 61 and the pressing wheel 51 can be increased, effectively preventing the pressing wheel 51 from rotating.
