[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] See also Figure 1-Figure 5 A cutting assembly for a printer includes a printer 10, wherein a paper outlet 100 is provided on the front wall of the printer 10, a storage platform 20 is provided in front of the paper outlet 100, a cutter assembly 40 is provided on the front side of the printer 10, and the cutter assembly 40 is slidably arranged relative to the printer 10; a downwardly recessed cutting avoidance groove 210 is provided on the upper surface of the storage platform 20 near the paper outlet 100. When the printed roll is output to the storage platform, when cutting, the cutter assembly is driven to slide left and right, and the roll is cut under the action of the cutter assembly. The setting of the cutting avoidance groove allows the blade that cuts through the roll to extend into the cutting avoidance groove, avoiding interference with the cutter and damage, which may cause safety problems.

[0023] See also Figure 3 The cutter assembly 40 includes a sliding block 410 that slides left and right relative to the printer 10. The sliding block 410 is connected to a first mounting base 420, which is connected to a second mounting base 430. The second mounting base 430 is provided with two sets of pinch rollers 440 that rotate forward and backward. A cutter 450 is mounted on the second mounting base 430 between the front and rear sets of pinch rollers 440. The pinch rollers 440 contact the printed web, keeping it flat and facilitating cutting by the cutter.

[0024] The sliding block 410 that slides left and right can facilitate quick cutting and easy operation to meet usage requirements.

[0025] See also Figure 3 and Figure 5 The front surface of the second mounting seat 430 is provided with a mounting cavity 431 recessed toward the rear side, and the cutter 450 is provided with an adjustment strip groove 451. The mounting cavity 431 is longitudinally arranged with two threaded holes 470. Two bolts 460 are passed through the adjustment strip groove 451 and are threadedly connected to the threaded holes 470; the bolt heads of the bolts 460 and the second mounting seat 430 clamp and fix the cutter 450; the blade of the cutter 450 extends into the cutting avoidance groove 210.

[0026] By adjusting the cooperation and locking of the strip groove 451 and the bolt 460, the cutter 450 can be adjusted up and down relative to the second mounting base 430. The bolt 460 is loosened during adjustment and tightened after adjustment.

[0027] See also Figure 3 and Figure 5 Each set of pressing rollers 440 includes two pressing rollers 440 spaced apart from each other, and the cutter 450 is disposed between the left and right pressing rollers 440. That is, the cutter 450 is disposed between the four pressing rollers 440, so that the paper remains flat and is easy to cut.

[0028] In the present invention, the sliding block 410 is connected to a driving handle 480. The function of the driving handle 480 is to facilitate manual operation of the sliding block 410 to slide left and right.
