[0035] When installing the label paper roller 3, the outer cover 12 is removed from the printer body 1, so that the two ends of the label paper roller 3 are respectively inserted and installed in the two clamping blocks 21, and then the two clamping blocks 21 are respectively clamped in the printer body 1, so that the slide grooves on the clamping blocks 21 are docked with the printer body 1. When installing, the pull block 23 is pressed downward or upward respectively. The movement of the pull block 23 will drive the compression spring 24 at the bottom of the clamping rod 22 to expand and contract, so that the clamping rod 22 retracts into the clamping block 21. After the clamping block 21 is inserted into the printer body 1, the lever block 23 is released, so that the clamping rod 22 is inserted into the plug hole in the printer body 1 through the return force of the compression spring 24, so that the clamping block 21 is clamped and fixed in the printer body 1, and the label paper roller 3 is placed in the printer body 1. When the label paper on the label paper roller 3 is used up, the label paper roller 3 can be quickly and conveniently moved out of the printer body 1 and replaced, which is convenient and fast to use.

[0036] Specifically, a rotating shaft 31 is respectively provided at both ends of the label paper roller 3, two limit blocks 32 are provided on one of the rotating shafts 31, and a bearing seat 33 is provided at the middle position of the two clamping blocks 21.

[0037] When the two ends of the label paper roller 3 are installed on the two clamping blocks 21, the two limit blocks 32 on the rotating shaft 31 of the label paper roller 3 are inserted into the arc groove in the bearing seat 33, and the two limit blocks 32 on the rotating shaft 31 are clamped into the limit arc seat in the bearing seat 33, so that the rotating shaft 31 at both ends of the label paper roller 3 can rotate on the two bearing seats 33 respectively. During the process of printing the label, the label paper can be rotated outward from the label paper roller 3 to facilitate subsequent printing of the label paper. When replacing the label paper roller 3, it only takes a simple plug-in installation to achieve the replacement of the label paper roller 3.

[0038] Specifically, the printing conveying adjustment structure 4 includes a conveying roller 41, two adjustment screws 42, two adjustment blocks 43 and two adjustment motors 44. Two adjustment grooves are provided on the side wall inside the printer body 1. The two adjustment blocks 43 are respectively arranged at the two ends of the conveying roller 41. The two ends of the conveying roller 41 are rotatably connected to the two adjustment blocks 43. The two adjustment motors 44 are symmetrically vertically arranged above the adjustment groove. The two adjustment screws 42 are respectively connected to the main shafts of the two adjustment motors 44. The adjustment screw 42 is rotatably connected in the adjustment groove, and the adjustment block 43 is threadedly connected to the adjustment screw 42.

[0039] Specifically, the printing and conveying adjustment structure 4 also includes a first moving roller 45, a second moving roller 46 and a third moving roller 47 which are rotatably connected to the printer body 1, the first moving roller 45 is located beside the label paper roller 3, the second moving roller 46 and the third moving roller 47 are located beside the conveying roller 41, and the first moving roller 45, the second moving roller 46 and the third moving roller 47 are arranged with an upper and lower interval between them and the conveying roller 41;

[0040] It should be noted that the label paper passes through the first moving roller 45, the conveying roller 41, the second moving roller 46 and the third moving roller 47 respectively during use. During use, the conveying roller 41 can be moved up and down to adjust the conveyed label paper so that the label paper is in a straightened state, so as to perform subsequent printing on the label paper.

[0041] In the process of adjusting the label paper, the two adjustment motors 44 can work simultaneously to drive the two adjustment screws 42 to rotate in the two adjustment slots respectively, and can drive the positions of the two adjustment blocks 43 to move up and down in the two adjustment slots respectively. The movement of the two adjustment blocks 43 will drive the position of the conveying roller 41 to move up and down in the vertical direction. In the process of conveying the label paper forward, the pressure of the label paper can be adjusted so that the label paper is in a straightened or stretched state during printing. There will be no wrinkles or folds on the label paper, which will affect the accuracy of the label printing, so that the font to be printed will be complete on the label paper during printing, and there will be no omissions.

[0042] Specifically, the label discharging structure 5 includes a lower discharging roller 51, which is horizontally rotatably connected to the printer body 1, and a first gear 52 is provided on the lower discharging roller 51.

A clamping spring 58 connected to the slider 57 is provided in the sliding groove, and a spring damper 59 is provided between the sliding groove and the slider 57.

[0044] After the label paper is printed, the conveying motor 54 drives the first gear 52 to rotate, which can drive the second gear 55 to rotate, thereby driving the lower discharge roller 51 to rotate in the printer body 1. In the process of conveying the label paper, due to the effect of gravity, the upper discharge roller 56 drives the position of the slider 57 to move downward, so that the upper discharge roller 56 is pressed against the lower discharge roller 51. The rotation of the lower discharge roller 51 drives the position of the label paper to move forward, and the printed label paper is moved upward to discharge the paper.

[0045] During the conveying process, the upper discharge roller 56 can move in the slide groove through the corresponding slider 57 according to the thickness of the label paper. The spring damper 59 will not cause the upper discharge roller 56 to shake during the up and down movement, and will not cause damage to the printed fonts and patterns on the label paper, or cause damage to the printed labels.

[0046] Specifically, the printer body 1 is provided with symmetrically arranged mounting plates 6, and the mounting plates 6 are provided with UV light lamps 61; after printing the label, the UV light lamps 61 can be operated to UV-cure the printed label, and the UV ink can be instantly cured under the irradiation of ultraviolet rays, which greatly improves the printing speed and reduces the drying time; high-quality printing: the UV-cured ink has the advantages of high gloss, wear resistance, chemical corrosion resistance, etc., and can provide high-quality printing effects.
