Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 1, 2 and 3, the thermal printer core in this embodiment includes a frame 1, and a rubber roller assembly 3, a printhead assembly 5, a motor 4, a transmission gear set 41 and a paper guide frame 2 which are arranged on the frame 1, the printhead assembly 5 is arranged on one side of the paper guide frame 2, the rubber roller assembly 3 is located above the paper guide frame 2 and has a gap for printing paper to pass through with the printhead assembly 5, the motor 4 drives the rubber roller gear 31 on the rubber roller assembly 3 through the transmission gear set 41, so as to drive the rubber roller assembly 3 to rotate, and a gear cover 42 is arranged outside the transmission gear set 41.
The frame 1 includes two side wall portions 12 arranged at an interval, and a connecting portion 11 and a bottom plate portion 13 connected between the side wall portions 12, the bottom plate portion 13 being located between bottom ends of the side wall portions 12.
The inner side of the side wall 12 has a sliding slot 14 with an outward port, correspondingly, two sides of the paper guide frame 2 are respectively provided with a sliding block 22 which is matched with the sliding slot 14 to position the paper guide frame 2, and a plurality of convex paper supporting ribs 21 are integrally formed on the paper guide surface at the upper end of the paper guide frame 2. The plurality of paper supporting ribs 21 are arranged at intervals and in parallel.
The rear end of the chute 14 has a positioning slot 15, correspondingly, one side of the slider 22 is provided with a positioning column 23, the slider 22 is located in the chute 14 when the paper guide frame 2 is assembled in the frame 1, and the positioning column 23 is disposed in the positioning slot 15. The bottom of the paper guide 2 abuts against the upper end surface of the bottom plate 13.
