Description

Technical Field

[0001] This utility model belongs to the field of label printing technology, specifically, it relates to a label printer. Background Technology

[0002] A label printer is a printer that can edit various characters such as text and barcodes and print them onto self-adhesive stickers using thermal printing. It can be used for signage in various places such as offices, factories, power plants, warehouses, and shopping malls.

[0003] Chinese utility model patent CN218505515U discloses a label printer, which consists of a main body and a mounting cover. The mounting cover is located above a placement compartment on the main body. A control panel on top of the main body is used to control the editing and printing of the content. The printed material is a thermal paper roll, and the desired content is printed on the thermal paper roll. The mounting cover is hinged to the top of the main body, and its bottom has a fixedly connected paper roll mounting bracket for holding the thermal paper roll. The mounting cover also has a sliding groove at a corresponding position. The groove has a sliding shaft inside, which passes through a movable connecting slide. Below the slide is a fixedly connected linkage plate, which is slidably connected to the shaft in the paper tube mounting frame. Because the sliding shaft has a surrounding reset member, and the two ends of the reset member are fixedly connected to one side of the slide and the inner wall of the groove, when the thermal paper roll is installed on the paper tube mounting frame, the linkage plate, together with the upper slide and reset member, can limit the position of the thermal paper roll to accommodate thermal paper rolls of different widths. Finally, with the help of the guide roller, one end of the thermal paper roll is guided into the printing part inside the main body for printing.

[0004] Although this printer can hold thermal paper rolls of different widths, if dust accumulates on the surface of the thermal paper roll during storage, it will affect the image presentation during printing, resulting in incomplete printing information and rendering the printer unusable. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] To address the problem mentioned in the background art that although the printer can hold thermal paper rolls of different widths, dust on the surface of the thermal paper rolls during storage affects image presentation during printing, resulting in incomplete printing information and rendering the printer unusable, the present invention adopts the following technical solution.

[0007] A label printer includes a printer housing with a mounting chamber. A thermal paper roll is detachably connected to the interior of the mounting chamber and mounted on a base. The base is detachably connected to the interior of the mounting chamber. The thermal paper roll is rotatable on the outer wall of the base. A fixed flip cover is rotatably connected to the top of the mounting chamber. A conveyor roller is provided on the printer housing, and a printing component is provided on one side of the conveyor roller. The thermal paper roll passes between the conveyor roller and the printing component. A mounting base is detachably connected to the bottom inner side of the mounting chamber. Connecting blocks are installed on both sides of the base, and connectors are detachably connected to the connecting blocks. Side baffles are fixedly connected to the opposite sides of the two connectors. A dust collection tube is rotatably connected between the two side baffles. A dust collection box is fixedly connected to the upper part of the two side baffles. The upper end of the dust collection box has an opening. The upper end of the dust collection box fits against the inner wall of the dust collection tube and is rotatably connected to the inner wall of the dust collection tube. A dust collection pipe is detachably connected to the outer wall of one side baffle. The dust collection pipe communicates with the inside of the dust collection box. A filter box is detachably connected to the dust collection pipe.

[0008] Preferably, the suction pipe extends out of the mounting base and is detachably connected to a filter box, a filter element is inserted inside the filter box, a pull handle is detachably connected to the upper end of the filter element, and the air inlet of a miniature air pump is detachably connected to the outer wall of the filter box.

[0009] Preferably, a brush roller is detachably connected between the two side baffles, and the dust collection box is embedded in the interior of the brush roller near the top.

[0010] Preferably, elastic telescopic rods are detachably connected to both sides of the interior of the mounting base, and the telescopic ends of the elastic telescopic rods are detachably connected to the bottom of the connecting block.

[0011] Preferably, a stepper motor and a gear set are installed on the printer housing. The stepper motor drives the conveyor roller to rotate and convey the thermal paper roll after being reduced in speed by the gear set.

[0012] Preferably, a switch arm is fixedly connected to one side of the fixed flip cover, and a switch shaft is provided on the switch arm, which allows the switch arm to be detachably connected to the outer wall of the printer housing.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. A miniature air pump generates suction at the dust collection box, drawing in dust from the outer wall of the mounting base where the thermal paper roll is in contact with the surface. The dust then enters the filter box through the suction pipe and is blocked by the filter element, thus preventing impurities and dust on the surface of the thermal paper roll from affecting the imaging effect. The filter element can be easily removed for cleaning or replacement via a pull handle. Furthermore, the fixed connection between the dust collection box and the side baffles ensures that the opening of the dust collection box always faces upwards, resulting in better dust collection.

[0015] 2. The brush roller is detachably connected to the side baffles on both sides, so that the brush roller will not rotate with the vacuum cleaner cylinder. When the vacuum cleaner cylinder rotates, the brush of the brush roller inserts into the hole on the vacuum cleaner cylinder and brushes out the dust stuck in the hole that cannot be sucked out. This can prevent the hole on the vacuum cleaner cylinder from being blocked and affecting the subsequent vacuuming effect.

[0016] 3. The vacuum cleaner contacts the bottom of the thermal paper roll. The elastic telescopic rod provides an upward thrust to the vacuum cleaner, which ensures that the thermal paper roll remains in contact with the bottom as it gets smaller during use. This prevents the bottom of the thermal paper roll from contacting the bottom of the installation chamber, thus reducing the chance of the thermal paper roll getting stuck during transport.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0027] like Figure 1 The diagram shows a preferred embodiment of a label printer according to this invention. The label printer of this embodiment includes a printer housing 100, a mounting chamber 102 on the printer housing 100, a thermal paper roll 103 detachably connected inside the mounting chamber 102, the thermal paper roll 103 mounted on a base, the base detachably connected to the inside of the mounting chamber 102, the thermal paper roll 103 being rotatable from the outer wall of the base, a fixed flip cover 101 rotatably connected above the mounting chamber 102, and a conveying roller 104 on the printer housing 100. A stepper motor and a gear set are installed on the printer housing 100. The stepper motor drives the conveyor roller 104 to rotate and convey the thermal paper roll 103 after the gear set reduces the speed. A printing component 107 is provided on one side of the conveyor roller 104. The thermal paper roll 103 passes between the conveyor roller 104 and the printing component 107. In this embodiment, the thermal paper roll 103 can be easily taken out or replaced by opening the fixed flip cover 101. The thermal paper roll 103 is conveyed by the rotation of the conveyor roller 104. The thermal surface of the thermal paper roll 103 is imaged by the heat generated by the printing component 107.

[0028] like Figure 1 As shown, a switch arm 106 is fixedly connected to one side of the fixed flip cover 101. A switch shaft 105 is provided on the switch arm 106. The switch shaft 105 allows the switch arm 106 to be detachably connected to the outer wall of the printer housing 100. In this embodiment, the fixed flip cover 101 can be opened by rotating the switch shaft 105 to release the limit between the switch arm 106 and the printer housing 100.

[0029] like Figure 1 as well as Figure 2 As shown, this is a schematic diagram of the suction cylinder structure in this embodiment. A mounting base 200 is detachably connected to the bottom inner side of the mounting chamber 102. Elastic telescopic rods 202 are detachably connected to both sides of the inner side of the mounting base 200. Connecting blocks 204 are detachably connected to the telescopic ends of the elastic telescopic rods 202. Connecting heads 203 are detachably connected to the connecting blocks 204. Side baffles 212 are fixedly connected to the opposite faces of the connecting heads 203 on both sides. A rotatable connection is formed between the two side baffles 212. In this embodiment, the dust collection net 201 contacts the bottom of the thermal paper roll 103. The elastic telescopic rod 202 provides an upward thrust to the dust collection net 201, which allows the thermal paper roll 103 to become smaller during use. The dust collection net 201 always remains in contact with the bottom of the thermal paper roll 103, preventing the bottom of the thermal paper roll 103 from contacting the inner bottom of the mounting chamber 102. This reduces the chance of the thermal paper roll 103 getting stuck during transport.

[0030] like Figure 3 as well as Figure 4 As shown, this is a schematic diagram of the vacuuming assembly structure in this embodiment. A vacuuming box 205 is fixedly connected to the upper part between the two side baffles 212. The upper end of the vacuuming box 205 is provided with an opening. The upper end of the vacuuming box 205 is attached to the inner wall of the vacuuming mesh cylinder 201 and is rotatably connected to the inner wall of the vacuuming mesh cylinder 201. A vacuuming pipe 207 is detachably connected to the outer wall of one side baffle 212. The vacuuming pipe 207 communicates with the inside of the vacuuming box 205. The vacuuming pipe 207 passes through the mounting base 200 and is detachably connected to a filter box 208. A filter element 209 is inserted into the inside of the filter box 208. A pull handle 210 is detachably connected to the upper end of the filter element 209. The wall is detachably connected to the air inlet of a miniature air pump 211. In this embodiment, the miniature air pump 211 generates suction at the dust collection box 205, thereby sucking in the dust that comes into contact with the outer wall of the mounting base 200 on the thermal paper roll 103. The dust then enters the interior of the filter box 208 through the suction pipe 207 and is blocked by the filter element 209. This prevents impurities and dust on the surface of the thermal paper roll 103 from affecting the imaging effect. The filter element 209 can be easily pulled out for cleaning or replacement by pulling the handle 210. Furthermore, the fixed connection between the dust collection box 205 and the side baffles 212 on both sides ensures that the opening of the dust collection box 205 always faces upward, thus improving the dust collection effect.

[0031] like Figure 3As shown, this is a schematic diagram of the cleaning component structure in this embodiment. A brush roller 206 is detachably connected between the two side baffles 212. The dust collection box 205 is embedded in the brush roller 206 near the top. In this embodiment, the brush roller 206 is detachably connected to the two side baffles 212 so that the brush roller 206 will not rotate with the dust collection cylinder 201. When the dust collection cylinder 201 rotates, the brush of the brush roller 206 inserts into the hole on the dust collection cylinder 201 and brushes out the dust stuck in the hole that cannot be sucked out, thereby avoiding the hole on the dust collection cylinder 201 from being blocked and affecting the subsequent dust collection effect.

[0032] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
