For example, the conveying roller and the tearing roller are arranged above the sliding platform, a plurality of bills are arranged between the conveying roller and the sliding platform, and meanwhile, the bills are driven by the conveying roller and the tearing roller to move rightwards between the tearing roller and the sliding platform; wherein the rotation speed of the tearing roller at the rear end is greater than that of the transmission roller at the front end; thereby increasing the tension between the two notes and causing the two notes to split along a row of through holes therebetween.
However, the automatic tearing device of the ticket in the prior art (as described in the above patent application) has the following problems: the gap between the tearing roll and the sliding platform (known to those skilled in the art as friction gap) is not easily understood.

When the friction force is increased to a certain degree, the tension among the bills is large enough to tear the bills, and the bills are accelerated to move forwards along with the rotating speed of the tearing roller 3 after being torn.
Therefore, the automatic tearing device for the bill provided by the utility model not only avoids the damage of the bill in the tearing process, but also avoids the difficulty in tearing the bill.

As is clear from the above description, the above arrangement provides a structure of the vertical reciprocating mechanism 4, and it is necessary to appropriately adjust the frequency of the up-and-down movement of the piston rod of the air cylinder 43 so that the frequency is adapted to the rotation speed of the conveying roller 2, so that the tearing roller 3 contacts exactly the middle of the single bill after moving downward.
Further, the device also comprises a rotation speed sensor and a controller, wherein the rotation speed sensor is used for monitoring the rotation speed of the transmission roller 2, and the controller is respectively connected with the rotation speed sensor and the air cylinder 43 in a communication mode.
As is apparent from the above description, the rotation speed sensor transmits the rotation speed of the transfer roller 2 to the controller, so that the controller can adjust the frequency of the up-and-down movement of the piston rod of the air cylinder 43 according to the rotation speed of the transfer roller 2.

the conveying roller 2 is rotatably connected above the sliding platform 1, and a friction gap for accommodating bills is formed between the conveying roller 2 and the sliding platform 1; the tearing roll 3 is parallel to the conveying roll 2 and is arranged at intervals;
the tearing roller 3 is rotationally connected above the sliding platform 1 through a vertical reciprocating mechanism 4, the tearing roller 3 is driven to reciprocate in the vertical direction by the vertical reciprocating mechanism 4, and an elastic layer 31 is arranged on the circumferential surface of the tearing roller 3.
The vertical reciprocating mechanism 4 comprises a sliding rail 41, a sliding block 42 and a cylinder 43;
the sliding rail 41 is vertically arranged on one side of the sliding platform 1, the sliding block 42 is in sliding connection with the sliding rail 41, the tearing roller 3 is rotationally connected with the sliding block 42, and the air cylinder 43 is in transmission connection with the sliding block 42. The tearing roll 3 can be driven by a motor through a transmission belt, the motor can be fixed on the sliding platform 1, and the movement of the tearing roll 3 is adapted by the rotation of the transmission belt.
The use and principle of the automatic tearing device for bills provided by the embodiment:

The tearing roller 3 vertically reciprocates under the drive of the vertical reciprocating mechanism 4, so that the tearing roller 3 can act on the middle part of a single bill when moving downwards, and the friction force of the tearing roller 3 on the bill can be gradually increased due to the soft elastic layer 31. When the friction force is increased to a certain degree, the tension among the bills is large enough to enable the bills to be torn, the tension among the bills after the bills are torn is cleared, and the bills are accelerated to move forwards along with the rotating speed of the tearing roller 3 after being torn.
