Further, the guiding block 15 is provided with a guiding inclined surface at a side far away from the transition channel 12, and the guiding inclined surface can facilitate the edge of the printing substrate 3 to be inserted between the guiding block 15 and the inlet support plate 14.
Illustratively, a pickup mechanism 4 is disposed between the paper feeding channel 11 and the transition channel 12, the pickup mechanism 4 includes a first paper pressing wheel 41, a pickup wheel 42 and a first driving unit for driving the pickup wheel 42 to rotate, the first paper pressing wheel 41 and the pickup wheel 42 are disposed opposite to each other in the vertical direction, and a first pinch channel capable of bringing a printing substrate 3 from the paper feeding channel 11 into the transition channel 12 is formed between the first paper pressing wheel 41 and the pickup wheel 42. The first paper pressing wheel 41 has a certain displacement space, and can be close to or far from the paper twisting wheel 42, and the first paper pressing wheel 41 presses the paper twisting wheel 42 or the printing substrate 3 under the action of a spring. Thus, when the first driving unit drives the pickup roller 42 to rotate, an engagement force is formed between the first platen roller 41 and the pickup roller 42 to bring the printing substrate 3 from the paper feeding path 11 into the transition path 12.
Further, the paper feeding channel 11 is provided with a second sensor 43 at a side close to the transition channel 12, the second sensor 43 is arranged on the inlet tray 14, and the second sensor 43 is electrically connected with the first driving unit; when the second sensor 43 detects that the printing substrate 3 is sent to the inlet pallet 14, the system controls the first driving unit to be started, and drives the paper pickup wheel 42 to drive the printing substrate 3 to be conveyed to one side of the transition channel 12.

Illustratively, the width of the printing end face 27 of the printing head 22 in contact with the printing substrate 3 is 0.3mm to 0.4 mm. Due to the design, the width of the contact part of the printing end face 21 of the printing head 22 and the printing base material 3 is only the width of one heating wire, and the perfect fit of the heating wire of the printing head 2 and the printing base material 3 is ensured.
