Description

Technical Field

[0001] This invention relates to the field of printer equipment technology, specifically to a thermal printer with an automated cleaning and lubrication function. Background Technology

[0002] The working principle of a thermal printer is that a semiconductor heating element is installed on the print head. After the print head heats up and comes into contact with the thermal paper, the desired pattern can be printed. Its principle is similar to that of a thermal fax machine. The image is generated by heating and producing a chemical reaction in the film.

[0003] However, existing thermal printers are not convenient for cutting labels at equal intervals after printing, and the printed paper is mostly torn manually after printing, making the outlet easily contaminated with various kinds of garbage, which reduces the efficiency of paper output. Therefore, a thermal printer with an automatic cleaning and lubrication function is needed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a thermal printer with an automated cleaning and lubrication function to solve the problems mentioned in the background art.

[0028] Example 1

[0029] Please see Figure 1-6 The present invention provides an embodiment of a thermal printer with an automated cleaning and lubrication function, comprising a cleaning and lubrication assembly 1, a material guiding assembly 2, a micro motor 3, a transmission assembly 4, and a printer body 5.

[0030] A material guide assembly 2 for support is fixedly installed on the front end face of the printer body 5. A cleaning and lubrication assembly 1 is fixedly installed on the upper end face of the material guide assembly 2. A micro motor 3 is fixedly installed on the side end face of the material guide assembly 2 near the rear. A transmission assembly 4 is rotatably engaged with the micro motor 3 on the inner end face of the material guide assembly 2.

[0031] The cleaning and lubrication assembly 1 includes a guide assembly 11, a fixed slide groove 12, a support shaft 13, a connecting gear 14, and a protective housing 15. The support shaft 13 is rotatably engaged near the center of the inner end face of the protective housing 15, and the connecting gear 14 is fixedly installed at the center of the side end face of the support shaft 13. The fixed slide groove 12 is provided on the outer end face of the support shaft 13, and the guide assembly 11 is slidably engaged on the outer end face of the support shaft 13 through the fixed slide groove 12.

[0032] The guide assembly 11 includes a connecting collar 111, a plug-in sliding shaft 112, a fixed side plate 113, a cutting blade 114, and a lubrication and cleaning plate 115. The plug-in sliding shaft 112 is fixedly installed on the inner end face of the connecting collar 111, and the fixed side plate 113 is installed near the top of the side end face of the connecting collar 111. The cutting blade 114 is installed near the end of the lower end face of the fixed side plate 113, and the lubrication and cleaning plate 115 is symmetrically installed near the bottom of the outer end face of the cutting blade 114.

[0033] The material guiding assembly 2 includes a support housing 22 for support. A material inlet 21 is provided in the middle of the rear end face of the support housing 22. A positioning plate 25 is provided in the front of the inner end face of the support housing 22. A transmission guide shaft 23 is symmetrically and rotatably engaged with the inner end face of the support housing 22 near the positioning plate 25. A material conveying roller 24 is fixedly provided on the outer end face of the transmission guide shaft 23. A transmission gear 26 is fixedly connected to the center of the side end face of the transmission guide shaft 23.

[0034] The transmission assembly 4 includes connecting teeth 41, a fixed clamping shaft 42, and a supporting turntable 43. The supporting turntable 43 is fixedly installed at the center of the front end face of the fixed clamping shaft 42, and the connecting teeth 41 are evenly and equidistantly arranged on the side end face of the supporting turntable 43.

[0035] The fixed slide 12 is adapted to the plug-in slide shaft 112, and the connecting collar 111 is adapted to the support rotating shaft 13. The guide component 11 is slidably engaged with the inner end face of the protective housing 15 through the fixed slide 12 and the plug-in slide shaft 112, and the connecting collar 111 and the support rotating shaft 13. This facilitates the subsequent operation of the support rotating shaft 13 through the cooperation of the fixed slide 12 and the plug-in slide shaft 112, thereby driving the cutting blade 114 to perform cyclic cutting of the printing paper and labels, thus improving the automation level of the equipment.

[0036] The two sets of lubrication and cleaning plates 115 are slidably engaged with the opening of the positioning plate 25. The sides of the two sets of transmission guide shafts 23 are meshed with the transmission gears 26, and the ends of the two sets of transmission guide shafts 23 are meshed with the transmission gears 26. This can effectively improve the stability of the transmission of the two sets of material conveying guide rollers 24, and also facilitate the subsequent conveying of printing paper or labels.

[0037] The side end face of the support turntable 43 is meshed with the transmission gear 26 through the connecting teeth 41, and the side end face of the support turntable 43 is meshed with the connecting gear 14 through the connecting teeth 41. When the support turntable 43 rotates once, it can provide power to the material guiding assembly 2 and the cleaning and lubrication assembly 1 respectively, which can effectively improve the power utilization efficiency of the equipment.

[0038] Working Principle: During use, if automatic equidistant cutting of printed labels or paper is required, the printer body 5 outputs the paper, and simultaneously the micro motor 3 starts, driving the support turntable 43 to rotate one revolution. As the support turntable 43 rotates, it drives the transmission gear 26 to rotate via the external connecting teeth 41. Since the radius of the connecting teeth 41 is much larger than the radius of the transmission gear 26, the support turntable 43 can drive the transmission gear 26 to rotate several revolutions. Simultaneously, the upper and lower sets of transmission gears 26 are meshed, allowing them to synchronously drive the feed guide roller 24 to rotate in opposite directions. This enables the feed guide roller 24 to guide the output paper. Once the paper is fully discharged, the connecting teeth 41 on the outside of the support turntable 43... 1. Disengages from the transmission gear 26, while the connecting gear 41 engages with the connecting gear 14, causing the connecting gear 14 to rotate one revolution. When the connecting gear 14 rotates, it drives the support shaft 13 to rotate, and the support shaft 13 drives the internal fixed slide groove 12 to rotate. Since the fixed slide groove 12 is a closed-loop slide, one revolution of the fixed slide groove 12 can drive the insertion slide shaft 112 to make one reciprocating displacement. At this time, the cutting tool 114 can cut the labels or printing paper exported from the positioning plate 25 at equal intervals. At the same time, the lubrication and cleaning plate 115 can clean the dust from the opening of the positioning plate 25 when the cutting tool 114 is cutting, improving the lubrication of the opening of the positioning plate 25, thereby improving the stability of the printing paper or label export and preventing paper jams.
