DETAILED DESCRIPTION

[0038] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0039] See also Figures 1 to 8 , is a printing assembly as the best embodiment of the utility model, comprising a head chip substrate 10, a rubber roller 20, and two substrate pressing blocks 30, wherein the rubber roller 20 is arranged corresponding to the head chip substrate 10; the two substrate pressing blocks 30 are arranged at both ends of the rubber roller 20; the substrate pressing blocks 30 are rotated, and the substrate pressing blocks 30 apply pressure to the head chip substrate 10 so as to generate a gap between the thermal head chip on the head chip substrate 10 and the rubber roller 20. The printing assembly of the utility model is provided with the substrate pressing blocks 30, and when the front cover 40 is opened, the substrate pressing blocks 30 can be driven to rotate and then apply pressure to the head chip substrate 10 of the thermal head chip group, so as to generate a gap between the thermal head chip group and the rubber roller 20, so as to facilitate the quick and convenient cleaning of paper jams. Furthermore, when a gap is generated between the thermal head chip group and the rubber roller 20, the thermal head chip of the thermal head chip group can be cleaned and maintained, so as to improve the printing quality and the service life of the thermal head chip.

[0040] Please refer to Figure 2 , Figure 5 The substrate pressing block 30 is provided with an abutting portion 32 for applying pressure to the head chip substrate 10 ; the substrate pressing block 30 includes a shaft sleeve portion 31 sleeved on the rubber roller 20 , and the abutting portion 32 is provided on the outer wall of the shaft sleeve portion 31 .

[0041] Please refer to Figure 4 , 5The substrate pressing block 30 is also provided with a first driving part 33 for driving the rotation thereof. When the first driving part 33 is pushed, the substrate pressing block 30 rotates, and the abutting part 32 applies pressure to the head substrate 10. The substrate pressing block 30 is also provided with a second driving part 34 for driving the rotation thereof. When the second driving part 34 is pushed, the substrate pressing block 30 rotates, and the abutting part 32 is separated from the head substrate 10. The first driving part 33 and the second driving part 34 drive the substrate pressing block 30 to rotate in different directions. The substrate pressing block 30 is driven to rotate by the front cover 40, and a protrusion for driving the rotation of the substrate pressing block 30 is provided on the front cover 40. Part 41, specifically, the front cover 40 is opened, the protrusion 41 first approaches the first driving part 33, and then continues to push, the substrate pressing block 30 continues to rotate, and makes the abutting part 32 abut against the head chip substrate 10. Since the head chip is basically provided with a supporting step 11, combined with the spring of the thermal head chip group, the abutting part 32 can maintain abutment. At this time, a gap is generated between the thermal head chip and the rubber roller 20, and the paper jam can be cleaned or the thermal head chip is located at this time; when the front cover 40 is closed, the protrusion 41 first approaches the second driving part 34, and then the substrate pressing block 30 continues to rotate, crossing the supporting step 11, and the thermal head chip is reset.

[0042] The first limiting portion 35 is provided on the substrate pressing block 30, and the first limiting groove 42 for the first limiting portion 35 to be embedded is provided on the front cover 40. The first driving portion 33, the second driving portion 34, the abutting portion 32 and the first limiting portion 35 are all provided on the outer wall of the shaft sleeve portion 31. The first driving portion 33, the second driving portion 34, the abutting portion 32, the first limiting portion and the shaft sleeve portion 31 adopt an integrated structure, and are formed by plastic parts and injection molding technology.

[0043] The printing assembly also includes a lower cover 50 and an upper cover 60 arranged above the lower cover 50, and the front cover 40 is rotatably connected to the upper cover 60; a second limiting portion 51 for limiting the upper cover 60 from rotating to open or close the cover is also provided on the lower cover 50, and a guide groove 43 cooperating with the second limiting portion 51 is provided on the front cover 40. Through the cooperation between the second limiting portion 51 and the guide groove 43, the front cover 40 can be stably opened or closed, and the front cover 40 can be placed in a recess; when the front cover 40 is opened at an angle α, the protruding portion 41 drives the substrate pressing block 30 to rotate, and when the front cover 40 is closed to an angle β, the protruding portion 41 drives the substrate pressing block 30 to rotate in the opposite direction; specifically, when the front cover 40 is opened at an angle α (α can be 11°), the protruding portion 41 abuts against the first driving portion 33 and drives the substrate pressing block 30 to rotate outward. At this time, the abutting portion 32 will rotate and continuously apply pressure to the head chip substrate 10. A supporting step 11 is set on the head chip substrate 10. Under the action of the spring, even if the front cover 40 is fully opened, the abutting portion 32 will abut against the supporting step 11, so that a gap is generated between the thermal head chip and the rubber roller 20, which is convenient for cleaning paper jams and other operations. When the front cover 40 is closed to an angle of β (β can be 20°), the protrusion 41 abuts against the second driving portion 34 and drives the substrate pressing block 30 to rotate. At this time, the abutting portion 32 will rotate in the opposite direction, push open the supporting step 11 and then pass over the supporting step 11 to remove the pressure on the head chip substrate 10. Under the action of the spring, the head chip substrate 10 will be lifted up and reset, and the front cover 40 will continue to be closed. Under the action of the first limiting groove 42 and the first limiting portion 35, the substrate pressing block 30 can be avoided from rotating on its own. Moreover, the abutting portion 32 cooperates with the protrusion 41 to better restrict the substrate pressing block 30 inside the front cover 40, thereby preventing problems such as shaking and abnormal noise.

[0044] The utility model also provides a printer which adopts the structure of the printing component.

[0045] To summarize, the printing component of the utility model is provided with a substrate pressing block. When the front cover is opened, the substrate pressing block can be driven to rotate and then apply pressure to the head chip substrate of the thermal head chip group, so as to generate a gap between the thermal head chip group and the rubber roller, so as to facilitate the quick and convenient cleaning of paper jams. Furthermore, when a gap is generated between the thermal head chip group and the rubber roller, the thermal head chip of the thermal head chip group can be cleaned and maintained, thereby improving the printing quality and increasing the service life of the thermal head chip.
