[0031] 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.

[0032] 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.

[0033] 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.

[0034] Example 1, referring to Figures 1 to 11 This is the first embodiment of the present invention, which provides an automatic paper cutter printer, which includes a printer body 1;

[0035] Specifically, the label paper tray 2 is located inside the printer body 1, and the detection and replacement assembly 3 is located inside the printer body 1. It includes a detection component 31 and a clamping component 32 located inside the printer body 1. The clamping component 32 is located inside the label paper tray 2.

[0036] Furthermore, the printer body 1 is equipped with a printing mechanism. After receiving an instruction, the printing mechanism drives specific heating points on the print head to be instantly energized, causing their temperature to rise rapidly. The high-temperature heating points contact the surface of the thermal paper, causing a chemical reaction in the coating. The colorless dye and the color developer melt and mix to produce color (usually black). The entire row of heating points on the print head is selectively heated according to the instruction, "burning" a row of dots on the label paper. Countless rows of dots are combined to form the text, barcode, or graphics we see. Then, the printing mechanism drives the roller to rotate, pulling the part of the label paper with the printed text out of the label paper tray 2 through friction.

[0037] The printer body 1 is equipped with an automatic cutting mechanism. After receiving the instruction, the cutting mechanism drives the toothed cutter to squeeze the label paper, so that the label paper is cut and neatly broken. At this time, the staff can easily remove part of the label paper from the label output port.

[0038] The label paper tray 2 is located inside the printer body 1 and is used to hold the label paper tube. The detection and replacement component 3 is used to monitor the usage of the label paper tube. When the usage of the label paper tube reaches a certain level, the detection component 31 immediately opens the paper tray cover, reminding the staff to replace the label paper tube with a new one. This reduces the steps of manually opening the paper tray cover and makes it easier for the staff to quickly replace the label paper tube for the printer body 1. The clamping component 32 is located inside the label paper tray 2. The label paper tube consists of a paper wheel and multiple layers of label paper wound on the paper wheel. The paper wheel is cylindrical. The clamping component 32 is located on the inner wall of the cylindrical paper wheel to increase the stability of the label paper tube rolling in the label paper tray 2.

[0039] Specifically, the testing component 31 includes a round rod 311 disposed inside the printer body 1, a round groove 312 is provided inside the round rod 311, a pressing rod 313 is disposed inside the round groove 312, a straight groove 314 is provided on the surface of the round rod 311, and a positioning rod 315 is disposed inside the straight groove 314.

[0040] Furthermore, the round rod 311 is located above the label paper compartment 2 and the label paper tube, the round groove 312 is opened in the middle of one end of the round rod 311, the extrusion rod 313 slides back and forth in a straight line in the round groove 312, the straight groove 314 is perpendicular to the round groove 312 and passes through both sides of the round rod 311, and the positioning rod 315 slides back and forth in a straight line in the straight groove 314.

[0041] Specifically, one end of the positioning rod 315 is equipped with a roller 316, which is located inside the label paper compartment 2;

[0042] Furthermore, roller 316 is located inside the label paper compartment 2 and is rotatably connected to one end of the positioning rod 315, contacting the surface of the label paper tube. At the same time, when the label paper tube rolls, roller 316 is subjected to the frictional force between the label paper tubes and rotates at one end of the positioning rod 315, thereby reducing the frictional force experienced by the label paper tube as it rolls in the label paper compartment 2.

[0043] Specifically, the printer body 1 has a paper tray cover at its end and a push plate at its end, with an inclined connecting rod between the push plate and the paper tray cover.

[0044] Furthermore, the paper tray cover is rotatably connected to one side of the printer body 1. When it is closed with the printer body 1, it triggers the tilting linkage to move into the printer body 1, locking the paper tray cover onto one side of the printer body 1. At the same time, the worker can manually press the push plate and trigger the tilting linkage to move outward from the printer body 1, releasing the locking and fixing between the paper tray cover and the printer body 1.

[0045] Specifically, the detection component 31 also includes a first spring 317 disposed between the circular groove 312 and the extrusion rod 313, and a second spring 318 disposed between the straight groove 314 and the positioning rod 315.

[0046] Furthermore, under the action of the first spring 317, the pressing rod 313 moves out of the circular groove 312 and contacts and presses against the side of the inclined connecting rod, causing the inclined connecting rod to move into the printer body 1 and automatically open the paper tray cover, making it convenient for staff to quickly replace the label paper tube. Under the action of the second spring 318, the positioning rod 315 ensures that the roller 316 at the end of the positioning rod 315 is always in contact with the surface of the label paper tube. When the label paper in the label paper tube is gradually consumed, the positioning rod 315 moves straight down in the straight groove 314.

[0047] Specifically, a snap-fit ​​element 33 is provided between the positioning rod 315 and the pressing rod 313.

[0048] Furthermore, the snap-fit ​​member 33 is located between the positioning rod 315 and the round rod 311, and is used to control the movement of the extrusion rod 313 in the round groove 312. When the positioning rod 315 moves to a certain extent in the straight groove 314, the extrusion rod 313 moves in the round groove 312 under the action of the first spring 317.

[0049] Specifically, the snap-fit ​​component 33 includes a first rectangular groove 331 and a second rectangular groove 332 formed on the surface of the positioning rod 315, and the end of the pressing rod 313 is provided with a first rectangular block 333 and a second rectangular block 334.

[0050] Furthermore, the cross-sections of the first rectangular groove 331, the second rectangular groove 332, the first rectangular block 333, and the second rectangular block 334 are all rectangular. The cross-section of the extrusion rod 313 is circular, and the diameter of the circular extrusion rod 313 is greater than the side length of the second rectangular block 334. The width of the first rectangular groove 331 is less than the width of the second rectangular groove 332, and the length of the first rectangular groove 331 is greater than the length of the second rectangular groove 332. The width of the first rectangular block 333 is less than the width of the second rectangular block 334. The width of the first rectangular block 333 is the same as the width of the first rectangular groove 331, and the width of the second rectangular block 334 is the same as the width of the second rectangular groove 332. Block 333 is located in the first rectangular groove 331. Under the action of the first spring 317, the extrusion rod 313 is in positive contact with the side of the second rectangular block 334 and the first rectangular groove 331. At the same time, when the positioning rod 315 moves downward in the paper straight groove 314, it drives the first rectangular groove 331 and the second rectangular groove 332 to move downward, so that the first rectangular block 333 moves into the second rectangular groove 332. At this time, under the action of the first spring 317, the extrusion rod 313 moves the second rectangular block 334 into the second rectangular groove 332, so that the extrusion rod 313 moves a distance in the circular groove 312 and makes extrusion contact with the inclined connecting rod, triggering the paper compartment cover to open.

[0051] Specifically, the clamping member 32 includes a shaft 321 disposed at the end of the printer body 1. The end of the shaft 321 is provided with a first connecting rod 322 and a second connecting rod 323. The shaft 321 is provided with a shaft groove 324. A moving rod 325 is disposed in the shaft groove 324. A third spring 326 is disposed between the shaft groove 324 and the moving rod 325.

[0052] Furthermore, the shaft 321 is located on one side of the middle part of the label paper compartment 2, the first docking rod 322 and the second docking rod 323 are rotatably connected to the end of one side of the shaft 321, the moving rod 325 slides back and forth in the shaft groove 324, and the third spring 326 always pushes the moving rod 325 to move in the direction of the first docking rod 322;

[0053] Specifically, a guide rod 327 is provided at one end of the first docking rod 322 and the second docking rod 323. Two arc-shaped grooves 328 are symmetrically provided at the end of the shaft rod 321, and the two guide rods 327 are respectively located in the corresponding arc-shaped grooves 328. Two guide grooves 329 are symmetrically provided at the end of the moving rod 325, and the two guide rods 327 are respectively located in the corresponding guide grooves 329.

[0054] Furthermore, two arc-shaped grooves 328 are located on both sides of the shaft 321, and the axes of the first connecting rod 322 and the second connecting rod 323 are located on both sides of the end of the shaft 321, causing the first connecting rod 322 and the second connecting rod 323 to tilt in opposite directions. A guide rod 327 is provided at one end of the first connecting rod 322 and the second connecting rod 323. When the first connecting rod 322 and the second connecting rod 323 rotate around the axis, the two guide rods 327 perform circular motion around the axis. Simultaneously, the guide rods 327 are located within the arc-shaped groove 328 on the shaft 321 and the guide groove 329 on the moving rod 325. The arc-shaped groove 328 forms the circular rotation trajectory of the guide rod 327. And is the angle range limiting area of ​​the guide rod 327. During the rotation of the guide rod 327, the surface of the guide rod 327 presses against the guide groove 329, causing the moving rod 325 to move in the shaft groove 324. When the first docking rod 322 and the second docking rod 323 are respectively placed into the paper wheel of the label paper tube, the moving rod 325 is pushed by the third spring 326 to move with the guide groove 329, causing the guide groove 329 to press the guide rod 327 to rotate in the arc groove 328, forcing the first docking rod 322 and the second docking rod 323 to rotate in opposite directions around the axis until the first docking rod 322 and the second docking rod 323 contact the inner wall of the paper wheel.

[0055] Specifically, one end of the first docking rod 322 and the second docking rod 323 is provided with a roller 3210, which is located inside the label paper compartment 2.

[0056] Furthermore, the two rollers 3210 roll against the inner wall of the rolling label tube, and at the same time, the two rollers 3210 support the label tube, improving the label tube's ability to maintain one end's posture and rotate around the shaft 321 while rolling. The rollers 3210 also rotate at one end of the first connecting rod 322 and the second connecting rod 323, reducing the friction force experienced by the label tube while rolling.

[0057] In use, the operator manually opens the paper tray cover by pressing the push plate. Then, the operator inserts one side of the label paper tube into the roller 3210 on the first connecting rod 322, pressing down on the first connecting rod 322. The first connecting rod 322 rotates around its axis, and the guide rod 327 at the end of the first connecting rod 322 presses against the guide groove 329, causing the moving rod 325 to move within the shaft groove 324. Simultaneously, the guide groove 329 on the other side of the moving rod 325 presses against the guide rod 327, causing it to rotate with the second connecting rod 323, thereby changing... The distance between the first connecting rod 322 and the second connecting rod 323 is such that when the label paper tube is inserted into the surfaces of the first connecting rod 322 and the second connecting rod 323, and the paper tray cover is manually closed, the tilting linkage is triggered to move outwards from the printer body 1, locking the paper tray cover in place. This gives the label paper tube a certain degree of stability within the label paper tray 2, and the label paper tube rolls around the shaft 321, which is beneficial for accurately detecting the label paper consumption of the label paper tube. Similarly, under the action of the third spring 326, the first connecting rod 322 and the second connecting rod 323... The roller 3210 at the end of the connecting rod 323 is in close contact with the label paper tube, and the positioning rod 315, under the action of the second spring 318, ensures that the roller 316 at the end of the positioning rod 315 is always in contact with the surface of the label paper tube. When the operator uses the printer body 1, the label paper on the surface of the label paper tube is gradually consumed, and the positioning rod 315 gradually moves downward in the straight groove 314. The first rectangular block 333 of the squeezing rod 313 gradually moves from the first rectangular groove 331 to the second rectangular groove 332. Under the action of the first spring 317, the second rectangular block 334 of the squeezing rod 313 moves into the second rectangular groove 332. At this time, the end of the squeezing rod 313 is in squeezing contact with the inclined connecting rod, causing the inclined connecting rod to move into the printer body 1, automatically triggering the push plate movement and opening the paper tray cover. This facilitates the operator to quickly replace the label paper tube of the printer body 1, reducing the embarrassing situation of the operator running out of label paper during busy periods, improving the efficiency of the operator in replacing the label paper tube, and reducing congestion in the workplace.
