Description

Technical Field

[0001] The utility model relates to the technical field of cloth-stacking machines, in particular to a cloth-feeding deviation-correcting device for cloth-stacking machines. Background Art

[0002] The existing cloth-stacking machine is equipped with a cloth-guided correcting roller and a position sensor. The cloth passes through the cloth-guided correcting roller. The position sensor is installed on the frame of the cloth-stacking machine. The position sensor senses the position of the cloth on both sides. If the cloth is displaced, the cloth-guided correcting roller is controlled to swing up and down by a cylinder on one side to correct the cloth. Since the entire cloth-guided correcting roller is very heavy, it is prone to slow response, poor cloth-guiding effect, high energy consumption, and loud noise. Utility Model Content

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below.

[0017] like Figures 1 to 3 As shown, a cloth feeding and correcting device for a cloth coding machine includes a frame 1, on which a cloth guide roller 2, a cloth feeding roller 3, a cloth wrapping roller 4 and a guide rod 5 are provided. The cloth guide roller 2 is connected to the side of the frame 1, and the frame 1 is connected to a support frame 6. The cloth feeding roller 3 is connected to the support frame 6 through a cloth feeding bracket. A motor 7 is installed under the frame 1, and the motor 7 drives the cloth feeding roller 3 to rotate, wherein a bearing seat is connected to the frame 1, and a transmission shaft 8 is connected between the bearing seats, the output end of the motor 7 is connected to a sprocket 1, and a sprocket 1 and a sprocket 2 are connected to the transmission shaft 8, and the sprockets 1 are connected by a chain 1 9, one end of the cloth feeding roller 3 is connected to a sprocket 2, and the sprockets 2 are connected by a chain 2 10, and the cloth feeding roller 3 is driven to rotate by the chain 1 9 and the chain 2 10.

[0018] The cloth wrapping roller 4 is connected to the cloth feeding roller 3 through the cloth wrapping bracket. The cloth wrapping roller 4 wraps the passed cloth around the outside of the cloth feeding roller 3. The guide rod 5 is connected to the top of the support bracket. Adjustment seats 11 that can slide left and right are provided on both sides below the cloth feeding roller 3. A cylinder 12 is installed at the bottom of the adjustment seat 11. The piston end of the cylinder 12 passes through the adjustment seat 11 and is connected to a support seat 13. A clamping roller 14 is rotatably connected to the support seat 13. The clamping roller 14 and the cloth feeding roller 3 clamp the cloth.

[0019] In this embodiment, a baffle is connected to the frame 1, and two guide columns 15 are connected between the baffles. The adjustment seat 11 is connected to the guide columns 15. In order to reduce the friction resistance during sliding, a linear bearing 16 is provided between the adjustment seat 11 and the guide columns 15. The linear bearing 16 is installed on both sides of the adjustment seat 11.

[0020] The guide rod 5 is connected to both sides with sensor brackets 17 that can slide left and right. Position sensors 18 are installed on the sensor brackets 17. When coding the cloth, the sensor brackets 17 are moved according to the width of the cloth, and the distance between the position sensors 18 is adjusted so that it can cooperate with the cloth. Then, the position of the clamping roller 14 is adjusted so that the clamping roller 14 can clamp both sides of the cloth.

[0021] The adjustment seat 11 is connected to a first locking screw 19, the sensor bracket 17 is connected to a screw seat, and the screw seat is threaded with a second locking screw 20. A through locking groove 21 is processed on the guide rod 5. After the position sensor 18 and the clamping roller 14 are adjusted, the adjustment seat 11 and the sensor bracket 17 are locked respectively by the first locking screw 19 and the second locking screw 20, wherein the threaded end of the second locking screw 20 is screwed into the locking groove 21.

[0022] During the cloth-stacking process, the clamping rollers 14 clamp the cloth on both sides of the cloth-feeding roller 3. When the position sensor 18 senses that the cloth is deflected to one side, the cylinder 12 on the deflected side descends to reduce the clamping force, while the cylinder on the other side remains stationary. Due to the inconsistent clamping forces on both sides, the cloth moves to the side with greater clamping force, thereby realizing the deviation correction function.

[0023] The present invention is not limited to the embodiments described. Those skilled in the art may make some modifications or changes without departing from the spirit or scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
