The third drive means is connected to and controlled by the control means (60).

The feeding assembly further comprises a feeding roller (27), the cylindrical materials (10) are arranged on the feeding roller (27), and the feeding roller (27) is connected to the screw rod (21) sliding blocks on the two sides respectively.

If the cylindrical material (10) is driven by the winding device (41) to rotate along the axis of the cylindrical material, the sheet material (71) is easy to damage under the condition that the sheet material (71) is thin or has poor toughness. For further improvement, the feeding assembly of the present application further comprises a power roller (22), the power roller (22) abutting the cylindrical material (10) and driving the cylindrical material (10) in rotation.

The pay-off subassembly of this application embodiment still includes the thrust arm, and the thrust arm is rotatory from the top butt cylindric material and drive cylindric material, and simultaneously, the thrust arm still diminishes and moves down along with the diameter of cylindric material to the thrust arm butt cylindric material.

Specifically, the thrust arm includes a power roller (22). The power roller (22) rotates along its axis and drives the cylindrical material in rotation. A power roller (22) of the thrust arm abuts against the cylindrical material (10) from above and drives the cylindrical material (10) to rotate. The power roller (22) is driven to rotate by a second drive means which includes a motor and a conveyor belt (26). It will be appreciated that the power roller (22) is able to drive the cylindrical material (10) to rotate when the power roller (22) rotates due to the frictional force between the power roller (22) and the cylindrical material (10).

Specifically, the pushing arm further comprises a connecting arm (23). The power roller (22) is rotatably arranged at one end of the connecting arm (23), and the other end of the connecting arm (23) is connected with the air cylinder (25).

The connecting arm (23) is driven to rotate by the air cylinder (25), specifically, the connecting arm (23) rotates around an axis (24) under the driving of the air cylinder (25), so that the power roller (22) at one end of the connecting arm (23) moves along with the connecting arm.

The cutter (31) passes through the groove of the positioning part (34).

In order to cut out a thin sheet (71), the thickness of the band-shaped blade is thin, and the blade is dull due to the fact that the blade is worn greatly during long-term use, thereby affecting the quality of the sheet (71). In order to further improve the slicing effect, the cutting assembly further comprises knife sharpening wheels (33), and the knife sharpening wheels (33) are respectively arranged on two sides of the strip-shaped blade. In the process of cutting the sheet material (71), the knife grinding wheel (33) continuously grinds the knife (31).

In order to improve the situation, the material collecting assembly further comprises a tension rod (42) which is rotatably arranged on the machine frame (50), and the sheet materials (71) reach the winding device (41) after passing through the tension rod (42). When the sheet material (71) is too tight in the winding process, the tension rod (42) is driven to rotate. The tension rod (42) is provided with a sensor (43), and the sensor (43) is used for detecting the rotation angle information of the tension rod (42) and transmitting the rotation angle information to the control device (60). The control device (60) can automatically judge whether the tension is too tight through program calculation, and if the tension is too tight, the control device controls the winding device (41) to decelerate or stop rotating. Therefore, the sheet material (71) can be prevented from being too tight to be broken or damaged in the rolling process.
