As shown in fig. 2, when the mode switch knob 118 is located in the manual gear 1181, the manual cutting button 114 is connected to the pneumatic cutting knife 12 through the mode switch knob 118, the click button 115 is connected to the driving device through the mode switch knob 118, if the manual cutting button 114 is pressed, the blade of the pneumatic cutting knife 12 moves downward and cuts off the adhesive tape 5 to be cut into two sections, if the click button 115 is clicked, the first driving device and the second driving device respectively drive the first traction roller 14 and the conveying roller 21 to rotate forward so as to drive the adhesive tape 5 to be cut to move for a set cutting length, and at this time, the hand cutting button 114 can be pressed again to complete the cutting off of the adhesive tape 5 to be cut for the second cutting length, and the click button 11 and the hand cutting button 114 are repeated in turn to complete the subsequent cutting off operation of the adhesive tape 5 to be cut.

Further, the left and right groove walls of the mounting groove 111 are respectively provided with a second mounting plate 112, a first adjusting screw 113 and a second inserting groove 119;

the two second insertion grooves 119 are respectively located above the left and right ends of the traction roller 14, the second mounting plates 112 are respectively inserted into the corresponding second insertion grooves 119 in a vertically movable manner, and the left and right ends of the first auxiliary roller 13 are respectively inserted into the two second mounting plates 112 in a rotatable manner;

the upper ends of the two first adjusting screws 113 are respectively located at the top of the left and right groove walls of the mounting groove 111, and the bottom ends of the first adjusting screws 113 penetrate through the corresponding groove walls of the mounting groove 111 and are in threaded connection with the corresponding second mounting plate 112.

As shown in fig. 2, the height of the first auxiliary roller 13 relative to the top surface of the traction roller 14 can be adjusted by rotating the two first adjusting screws 113, so that the distance between the bottom surface of the first auxiliary roller 13 and the top surface of the traction roller 14 is adjusted to be suitable for traction of adhesive tapes with different thicknesses.

Further, the top parts of the two conveying frames 23 are respectively provided with a second adjusting screw rod 25;

the upper ends of the two second adjusting screws 25 are respectively located at the tops of the two conveying frames 23, and the bottom ends of the second adjusting screws 25 penetrate through the corresponding groove walls of the mounting groove 111 downwards and then are in threaded connection with the corresponding first mounting plates 24.

As shown in fig. 4, the height of the second auxiliary roller 22 relative to the top surface of the conveying roller 21 can be adjusted by rotating the two second adjusting screws 25, so that the distance between the bottom surface of the second auxiliary roller 22 and the top surface of the conveying roller 21 is adjusted to be suitable for conveying adhesive tapes with different thicknesses.

In summary, in the embodiment of the utility model shown in fig. 1-5, the adhesive tape 5 to be cut wound on the unreeling wheel 3 is pulled by the pulling roller 14, then the manual cutting button 114 is pressed and the adhesive tape can be cut by the pneumatic cutting knife 12, so that the operator does not need to contact the adhesive tape 5 to be cut in the whole cutting process, the operation is convenient and safe, and the production efficiency is high.

The technical principle of the present utility model is described above in connection with the specific embodiments. The description is made for the purpose of illustrating the general principles of the utility model and should not be taken in any way as limiting the scope of the utility model. Other embodiments of the utility model will be apparent to those skilled in the art from consideration of this specification without undue burden.
