[0051] The dust removal roller 1001 is cleaned by removing the dust on the dust removal roller 1001 through the sticky dust roll. When the outer periphery of the sticky dust roll is full of dust, the staff tears off the outermost sticky paper until all the sticky dust papers are used up, and then the sticky dust roller 1002 is disassembled and replaced with a new sticky dust roll.

[0056] The position of the spacing control sensor can be adjusted in a large range by adjusting the position of the movable roller 205 and rotating the cylindrical seat 2031. The position of the spacing control sensor can be adjusted in a small range by rotating the hand button 20512 to rotate the movable screw 20513 and drive the mounting seat 202 to move.

[0057] In some embodiments, see Fig.10 and Fig.11 A positioning unit 110 is provided on the rear side of the body 10, and the positioning unit 110 includes a support plate 1101, a pressure strip 1102 and a telescopic member 1103. The support plate 1101 is fixedly connected to the body 10 and is tilted downward from front to back; a plurality of pressure strips 1102 are provided, and are sequentially spaced along the front-to-back direction; the telescopic member 1103 is telescopic in length along a direction perpendicular to the tilt direction of the support plate 1101, the fixed end of the telescopic member 1103 is fixedly connected to the support plate 1101, and the movable end of the telescopic member 1103 is fixedly connected to the end of the pressure strip 1102.

[0058] The telescopic members 1103 correspond to the pressure strips 1102 one by one, or one pressure strip 1102 corresponds to at least two telescopic members 1103 .

[0059] It should be noted that the structure in the figure corresponds to one pressure strip 1102 and two telescopic members 1103 , and the telescopic members 1103 can be telescopic oil cylinders, electric cylinders, or hydraulic cylinders.

[0060] Specifically, the telescopic member 1103 is communicatively connected with the spacing control sensor.

[0061] When the spacing control sensor detects the point position, it means that the forward distance of the roll material has reached the preset distance. At this time, the spacing control sensor transmits a stop signal to the power component 201. At this time, the power component 201 stops working after receiving the stop signal, and the roll material no longer moves forward; at the same time, the spacing control sensor transmits a start signal to the telescopic member 1103, and the telescopic member 1103 starts to drive the pressure bar 1102 to move toward the direction close to the support plate 1101 until the roll material is pressed against the support plate 1101, so that the position of the roll material will not shift during the printing process.

[0062] After printing is completed, the power assembly 201 is started again to drive the roll material forward, and at the same time, the telescopic member 1103 drives the pressure bar 1102 to move away from the support plate 1101.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
