Fig. 7 is a schematic structural view of the print module and the front surface of the main frame 60, and fig. 8 is a schematic structural view of the main frame 60 and the stand 42. As shown in fig. 7 and 8, the upper portion of the main frame 60, which is located on the side where the label paper tube 21 is located, includes a guide channel 65 for guiding the movement of the label paper 20, and one end of the guide channel 65 is communicated with the recessed area where the label paper tube 21 is installed, and the other end is communicated with the opening of the housing for protruding the label paper 20, so that the label paper 20 protruding from the label paper tube 21 extends to the opening of the housing through the guide channel 65. The pickup roller 64 and the print head 81 are located at the outer end portion of the guide passage 65 (i.e., the end portion near the opening of the housing), and the pickup roller 64 and the print head 81 are located at both sides of the guide passage 65, respectively. The rotation surface of the pickup roller 64 is sleeved with a pickup sleeve to increase the friction coefficient, and when the motor 63 drives the pickup roller 64 to rotate through the transmission gear 61, the pickup sleeve contacts the label paper 20, so that the label paper 20 can be driven to move along the guide channel 65, and the label paper 20 extends out of the opening of the housing through the gap between the pickup roller 64 and the print head 81. Also, the opposite type photo sensors 51 are positioned at both sides of the guide passage 65 so that the label paper 20 passes between the opposite type photo sensors 51 to detect the label paper 20.

In order to facilitate replacement of the label paper tube 21, the printing module of the thermal label printer according to this embodiment further includes a bracket 42, an unlocking handle 40, and a spring 421. As shown in fig. 8, the bracket 42 has a substantially 7-shaped structure, one end of which faces the outer end of the guide passage and is connected to the print head 81. The middle portion of the bracket 42 is hinged to the main frame 60 such that the bracket 42 is rotatably connected to the main frame 60. When the bracket 42 rotates, the bracket 42 drives the print head 81 to approach or separate from the pickup roller 64.

In this embodiment, in order to facilitate the rotation of the driving bracket 42, the unlocking handle 40 is movably connected to the main frame 60 and is hinged to the bracket 42, and when the unlocking handle 40 moves, the bracket 42 is driven to rotate to move the printing head 81. Moreover, the unlocking handle 40 includes a paper blocking portion 41, and when the unlocking handle 40 pushes the bracket 42 to rotate so that the printing head 81 approaches the pickup roller 64, the paper blocking portion 41 protrudes out of the side surface of the label paper 20 to guide the label paper 20. One end of the spring 421 abuts against the main frame 60, and the other end abuts against the print head 81, so as to apply an elastic force to the print head 81 toward the pickup roller 64.

Before printing, the printer is in a state of being more labeled with the paper 20. At this time, the unlocking lever 40 is in the OFF position, and the bracket 42 is rotated to a position where the print head 81 is located away from the pickup roller 64. The user can mount the label paper cartridge 21 to the mounting post and place the label paper 20 in the guide channel 65, protruding from the end of the guide channel 65.

When printing is needed, the unlocking push handle 40 is pushed to move, the unlocking push handle drives the support 42 to rotate, so that the printing head 81 is close to the position of the paper twisting roller 64, and at the moment, the paper blocking part 41 of the unlocking push handle 40 is located at the position of the guide channel 65, and therefore inclination and deviation can be prevented from being known. When the label printer works, the motor 63 drives the pickup roller 64 to rotate through the transmission gear 61, so as to drive the label paper 20 to move along the guide channel 65, and the printing head 81 extends out of the port of the guide channel 65 after printing on the label paper 20, so that printing is completed.

The thermal label printer is characterized in that the printing head 81 is connected to the support 42 rotatably connected to the main frame 60, and the printing head 81 can be driven to be close to or far away from the paper twisting roller 64 by rotating the support 42, so that the switching between the paper assembling state and the printing state is realized, only the parts for unlocking the printer are reduced, the structure of the printer is simplified, and the cost of the printer is reduced.

Moreover, the above-mentioned correlation type photoelectric sensor 51 of the thermal label printer includes a transmitting and receiving device, which is directly connected to the circuit board 50 through pins, thereby avoiding the use of a flexible flat cable for connecting the circuit board 50, and reducing the cost and assembly complexity of the printer. Further, foretell thermal label printer adopts integration module structure, and circuit board 50 and print module connect in main frame 60 independently, and main frame 60 is installed on installing support body 30, has reduceed the part of printer and the degree of connection of casing, need not correspond the inside device module of modification again at the in-process of change casing, has also reduced the cost of printer, can conveniently match multiple outward appearance molding.
