Description

Technical Field

[0001] The utility model relates to a printer, in particular to a label printer, belonging to the technical field of thermal transfer printing. Background Art

[0002] Thermal printing technology utilizes a print head that heats the printed area. As the temperature rises, the colorless heat-sensitive chemical coating on the thermal label undergoes a chemical reaction, turning black, revealing text and images. This printing method eliminates the need for consumables like ribbons and offers advantages such as fast printing speed, low cost, and ease of use. It is ideal for applications requiring high speed and cost-effectiveness, such as pharmaceutical price labels.

[0003] The existing technology for installing thermal paper is to fix one side while moving the other side. This solution is gradually being eliminated. The disadvantage is that the smaller the width of the consumables, the smaller the contact surface between the printing consumables and the printing component. When uneven printing force is applied, the probability of printing problems increases greatly. For this solution with two sides moving, A, the use of damping gears will increase the cost and require a relatively high damping value. Otherwise, the thermal paper will move during use, and the stability will be poor. B, when the plastic of the rotating paddle is subjected to force, the plastic deforms and clamps the limiting tooth groove to fix it in the specified position. Because the rotating paddle only uses one tooth to clamp in the limiting tooth groove, the service life will be limited by the wear of the plastic and the service life is short. To this end, we provide a label printer to solve the above problems. Utility Model Content

[0004] In order to solve the above problems, the present invention provides a label printer to solve the above problems. The specific technical solution is as follows:

[0005] The label printer comprises an upper shell, wherein the upper shell is provided with an engaging mechanism, the upper shell is provided with a fixing mechanism, the upper shell is installed with a right baffle, the upper shell is provided with a first through slot, and the upper shell is provided with a second through slot.

[0006] Preferably, the meshing mechanism includes a gear, the gear is installed at the bottom of the upper shell, a stopper is installed below the upper shell, the stopper is installed with a second screw, and the gear is meshed with a left rack.

[0007] Preferably, the left rack is mounted with a third screw, the gear is meshed with a right rack, and the right rack is mounted with a fourth screw.

[0008] Preferably, the fixing mechanism includes a left baffle, the left baffle is mounted on the upper portion of the upper shell, the left baffle is mounted with a rotating paddle, and the rotating paddle is mounted with a fifth screw.

[0009] Preferably, the left baffle is installed with a stop block, the stop block is installed inside the left rack, and the stop block is installed with a spring.

[0010] Preferably, a lower shell is installed below the upper shell, and the lower shell is installed with a plurality of first screws.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The label printer places the thermal paper between the left baffle and the right baffle, and then pushes the stop block to move toward the thermal paper, thereby driving the left rack to move in the same direction, thereby driving the right baffle to move in the opposite direction. Finally, the left and right baffles clamp the thermal paper, and by pushing the rotary paddle forward, the stop block is driven to sink, and the cylindrical position of the stop block is pressed against the tooth groove inside the lower shell, and a compressive force is applied to the spring, thereby fixing the left rack and the right baffle at the same time, achieving the purpose of bidirectionally clamping and fixing the thermal paper of the device, ensuring the function of the device, increasing the service life, reducing the processing accuracy of the plastic, reducing the production difficulty, increasing the stability of the product use process, and achieving the high efficiency of the device.

[0013] 2. The label printer pushes the rotary paddle backward, which drives the stop block to rise under the action of the spring elasticity, and at the same time releases the cylindrical position of the stop block from pressing against the tooth groove inside the lower shell, and then pushes the stop block to move away from the thermal paper, thereby driving the left rack to move in the same direction, thereby driving the right rack to move in the opposite direction, and at the same time driving the right baffle to move in the opposite direction. Finally, the left and right baffles release the clamping of the thermal paper, thereby achieving the purpose of convenient replacement of thermal paper in this device.
