Description

Technical Field

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

[0002] The working principle of a thermal document printing module 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, it can print the required patterns and text. It mainly consists of a print head, a transmission mechanism, a control system, and a power supply system. It is the main component of a thermal printer. A thermal printer is a printing device that uses thermal printing technology to print information such as text, images, and barcodes. It heats the print head to cause a chemical reaction in the photosensitive layer on the thermal paper or thermal label, thereby generating the required content on the paper.

[0003] Chinese utility model patent CN220973706U discloses a thermal document printing module. The module uses two conical platforms whose sides abut against the ends of hollow holes in a roll of thermal paper, thus suspending the roll of thermal paper on a support rod. The sides of the two conical platforms can accommodate rolls of thermal paper with different hollow hole sizes. During rotation, the surface of the roll of printing paper never comes into contact with the inner wall of the paper tray, effectively reducing frictional resistance during rotation and preventing slippage and paper feeding problems caused by the rotating rollers.

[0004] Although the thermal printing module can reduce the frictional resistance encountered by the thermal paper during rotation, it limits the two truncated cones by means of limiting pins and through holes. However, if the limiting position is located between the two through holes, it cannot limit the truncated cones, and therefore cannot limit the thermal paper tube. 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 thermal printing module can reduce the frictional resistance encountered by the thermal paper during rotation, it cannot limit the two truncated cones by means of limiting pins and through holes. However, if the limiting position is located between the two through holes, the truncated cones cannot be limited, and thus the thermal paper tube cannot be limited. Therefore, the present invention adopts the following technical solution.

[0007] A label paper mounting structure for a printer includes a thermal printer housing. A core support is detachably connected to one side of the thermal printer housing. An adjustment cover is rotatably connected to the upper end of the thermal printer housing, and a thermal printing assembly is mounted on the adjustment cover. Switch arms are located on both sides of the thermal printer housing, and switch shafts are mounted on the switch arms. A feed roller is located on the thermal printer housing near the thermal printing assembly. A paper tray is located on one side of the thermal printer housing, and thermal paper is placed inside the paper tray. The thermal paper passes through the feed roller and between itself and the thermal printer. A PCB main control board is located on the inner bottom of the core support. Paper is wound around the outside of a paper winding tube. Inside the paper winding tube, there are movable blocks on both sides. Two bidirectional adjusting screws are threaded onto the movable blocks on both sides. The two ends of the bidirectional adjusting screws pass through the movable blocks and are fixedly connected to adjusting blocks. A sliding rod is set between the two adjusting blocks on both sides. The sliding rod is slidably connected to the two movable blocks on both sides and can revolve in a circle around the adjusting blocks. Inserted round blocks are rotatably connected to the opposite sides of the two adjusting blocks on both sides. Multiple mounting grooves are set on the opposite sides of the two movable blocks on both sides. A rotating plate is rotatably connected inside each mounting groove. A support block is rotatably connected between every two opposite rotating plates. The inserted round blocks on both sides are placed inside the mounting grooves on both sides.

[0008] Preferably, a connecting block is fixedly connected to the outer wall of the opposite side of the two movable blocks, and a first connecting plate is detachably connected to the bottom of the connecting block. A sliding rod is elastically telescopically connected inside the first connecting plate, and the sliding rod has a force that retracts into the first connecting plate. A second connecting plate is fixedly connected to the bottom of the first connecting plate, and limit blocks are installed on the opposite sides of the two second connecting plates. A rotating shaft is rotatably connected between the two limit blocks, and the rotating shaft is in contact with the bottom of the thermal paper.

[0009] Preferably, a connector is fixedly connected to the top of the first connecting plate, the connector is inserted into the bottom of the connecting block, and a fastening bolt is detachably connected to the outer wall of the connecting block, with the threaded end of the fastening bolt contacting the outer wall of the connector.

[0010] Preferably, the two sides of the second connecting plate are fixedly connected to the opposite surfaces near the bottom with plug rods, and the two sides of the rotating shaft and the limiting block are provided with plug holes, and the plug rods are plugged into the plug holes.

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

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. When fixing the paper roll, insert a circular block on one side through the paper roll, pinch the circular blocks on both sides and rotate the adjusting block on one side to rotate the bidirectional adjusting screw, which in turn causes the moving blocks on both sides to move in opposite directions at the same time. Multiple rotating plates rotate outward and push the support block outward to contact the inner wall of the paper roll, thereby fixing the paper roll stably.

[0014] 2. The rotating shaft, which is in contact with the bottom of the thermal paper, can rotate as the thermal paper rotates. The limiting blocks on both sides can limit the edge of the thermal paper to prevent it from shifting during transport. The retraction of the sliding rod can keep the rotating shaft in contact with the bottom of the thermal paper, thus preventing the thermal paper from contacting the bottom of the thermal printer housing during transport and causing friction damage.

[0015] 3. By making the first connecting plate and the connecting block detachable, it is easier to insert the side moving block into the inside of the winding paper tube when installing the winding paper tube.

[0016] 4. By inserting the plug rod into the plug hole, the second connecting plate can move along with the moving block, thus avoiding any restriction on the movement of the moving block. Attached Figure Description

[0026] 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.

[0027] 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.

[0028] like Figure 1The diagram shows a preferred embodiment of a printer label paper mounting structure of this utility model. The printer label paper mounting structure of this embodiment includes a thermal printer housing 100. A core support 107 is detachably connected to one side of the thermal printer housing 100. An adjusting cover 101 is rotatably connected to the upper end of the thermal printer housing 100, and a thermal printing assembly is mounted on the adjusting cover 101. Switch swing arms 106 are provided on both sides of the thermal printer housing 100, and switch shafts 105 are mounted on the switch swing arms 106. A conveyor roller 104 is provided near the thermal printing assembly in the thermal printer housing 100. A stepper motor and a gear set are installed inside the thermal printer housing 100. The stepper motor is connected to the gear set... After deceleration, the conveyor roller 104 rotates to transport the thermal paper 108 outward. A paper tray 102 is provided on one side of the thermal printer housing 100. The thermal paper 108 is placed inside the paper tray 102. The thermal paper 108 passes between the conveyor roller 104 and the thermal printer. A PCB main control board 109 is provided on the inner bottom of the machine core bracket 107. The thermal paper 108 is wound around the outside of the winding paper tube 110. In this embodiment, data commands are sent to the printer main control board through the upper-level software to drive the stepper motor, which in turn drives the stepper motor, gear set, and conveyor roller 104 to transmit the thermal paper 108. Simultaneously, the thermal head module generates heat through data commands to heat the thermal surface of the thermal paper 108, so that fonts, symbols, and other content are printed out.

[0029] like Figure 2 As shown, this is a schematic diagram of the support block structure in this embodiment. The thermal printer housing 100 has mounting grooves on both sides of its interior. The winding paper tube 110 has movable blocks 200 on both sides of its interior. Bidirectional adjusting screws 204 are threaded onto the movable blocks 200 on both sides. The two ends of the bidirectional adjusting screws 204 pass through the movable blocks 200 and are fixedly connected to adjusting blocks 205. A sliding rod 207 is provided between the two adjusting blocks 205. The sliding rod 207 is slidably connected to the two movable blocks 200 on both sides, and the sliding rod 207 can revolve in a circle around the adjusting blocks 205. Insertable circular blocks 206 are rotatably connected to the opposite sides of the two adjusting blocks 205. Multiple mounting grooves 201 are provided on the opposite sides of the two movable blocks 200. A rotating plate 202 is rotatably connected inside each mounting groove 201. A support block 203 is rotatably connected between every two opposing rotating plates 202. Two side-mounted round blocks 206 are placed inside the mounting grooves on both sides. In this embodiment, when fixing the winding paper tube 110, one side-mounted round block 206 is passed through the winding paper tube 110. By pinching the two side-mounted round blocks 206 and rotating one side-mounted adjusting block 205, the bidirectional adjusting screw 204 can be rotated, thereby enabling the two side moving blocks 200 to move towards or away from each other at the same time. Multiple rotating plates 202 rotate outward and push the support block 203 outward to contact the inner wall of the winding paper tube 110, thereby enabling the winding paper tube 110 to be stably fixed.

[0030] like Figure 3 As shown, this is a schematic diagram of the rotating shaft structure in this embodiment. Connecting blocks 300 are fixedly connected to the outer walls of the opposite sides of the two moving blocks 200. A first connecting plate 301 is detachably connected to the bottom of the connecting block 300. A sliding rod 302 is elastically telescopically connected inside the first connecting plate 301. The sliding rod 302 has a force that contracts inward towards the first connecting plate 301. A second connecting plate 303 is fixedly connected to the bottom of the first connecting plate 301. Limiting blocks 305 are installed on the opposite surfaces of the two second connecting plates 303. A rotating shaft 30 is rotatably connected between the two limiting blocks 305. 4. The rotating shaft 304 is in contact with the bottom of the thermal paper 108. In this embodiment, the rotating shaft 304 can rotate when the thermal paper 108 is rotated because it is in contact with the bottom of the thermal paper 108. The limiting blocks 305 on both sides can limit the edge of the thermal paper 108 to prevent the thermal paper 108 from deviating during transportation. The contraction of the sliding rod 302 can keep the rotating shaft 304 in contact with the bottom of the thermal paper 108, thereby preventing the thermal paper 108 from contacting the inner bottom of the thermal printer housing 100 during transportation and causing friction damage to the thermal paper 108.

[0031] like Figure 4 As shown, this is a schematic diagram of the connector structure in this embodiment. The top of the first connecting plate 301 is fixedly connected to the connector 307, which is inserted into the bottom of the connecting block 300. The outer wall of the connecting block 300 is detachably connected to the fastening bolt 306, and the threaded end of the fastening bolt 306 contacts the outer wall of the connector 307. In this embodiment, by making the first connecting plate 301 and the connecting block 300 detachable, it is more convenient to insert the side moving block 200 into the inside of the winding paper tube 110 when installing the winding paper tube 110.

[0032] like Figure 4 As shown, the two sides of the second connecting plate 303 are fixedly connected to the opposite surfaces near the bottom with plug rods 308. The two sides of the rotating shaft 304 and the limiting block 305 are provided with plug holes 309. The plug rods 308 are inserted into the plug holes 309. In this embodiment, by inserting the plug rods 308 into the plug holes 309, the second connecting plate 303 can move with the moving block 200, thus avoiding any restriction on the movement of the moving block 200.

[0033] 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.
