[0045] Furthermore, the surface of the pushing roller 9-3 is a frosted anti-slip structure surface.

[0046] In this embodiment, the friction force when the push roller 9-3 contacts the ton bag is increased by the frosted anti-skid structural surface, ensuring that the ton bag can be driven to move.

[0047] Furthermore, the connecting seat 8 - 2 can be turned upward by 90° at the connection with the outer groove 5 .

[0048] In this embodiment, the upward flip angle of 90° facilitates the clamping wheel 8-6 ​​to be rotated upward and opened through the connecting seat 8-2, and can be opened during deployment and when not in use.

[0049] When it is necessary to sew a ton bag, put the ton bag into the positioning frame 7-9, and insert one side into the moving groove 7-2, start the telescopic cylinder 7-10 to push the clamping plate 7-11 to clamp the ton bag, start the driving screw 7-6 to drive the moving block 7-8 to move along the guide rod 7-7, and the outer side of the ton bag enters between the clamping wheel 8-6 ​​and the stand 1 and keeps fitting, start the driving motor 8-4 when starting to move, and the rotation speed of the clamping wheel 8-6 ​​is consistent with the movement of the ton bag, and when the ton bag passes the outer groove 5, start the sewing equipment body 6 to start sewing, and after sewing is completed, start the second cylinder 9-2 to control the push roller 9-3 to move downward and press on the surface of the ton bag, and finally start the push roller 9-3 to move the ton bag outward and take it away.

[0050] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
