Description

Technical Field

[0001] This utility model relates to the field of printer technology, and in particular to a printer with a preheating structure. Background Technology

[0002] In existing printers, especially thermal, thermal transfer, and 3D printing equipment, print quality is highly dependent on the stability of the print head, printing media (such as thermal paper, ribbon, and printing materials), and ambient temperature.

[0003] A thermal printing structure with a preheating element, disclosed in CN219191673U, includes a printing housing. A first preheating component and a second preheating component are installed in the middle of the printing housing. A temperature sensor is installed between the first and second preheating components. A paper feeding roller mechanism and a thermal printhead are installed in the middle of the printing housing. Both the first and second preheating components include a heating tube and a preheating roller assembly sleeved on the heating tube and the preheating roller assembly. This invention preheats the paper before printing, thus making the printer unaffected by external ambient temperature during use. Furthermore, the cooperation of the two preheating components ensures better control of the paper preheating temperature, facilitating printing operations for the thermal printhead. However, because the preheating roller assembly is installed inside a metal drum in this thermal printing structure, it is inconvenient to inspect and replace the preheating roller assembly when it is damaged, affecting equipment maintenance efficiency.

[0004] Therefore, a printer with a preheating structure has now been developed that can quickly and easily inspect or replace the heating element, improving equipment maintenance efficiency. Utility Model Content

[0005] To overcome the shortcomings of existing thermal printing structures where the preheating roller assembly is installed inside a metal barrel, making it inconvenient to inspect and replace when the preheating roller assembly is damaged, this utility model provides a printer with a preheating structure that enables quick and convenient inspection or replacement of the heating element, thereby improving equipment maintenance efficiency.

[0006] The technical implementation scheme of this utility model is as follows: A printer with a preheating structure includes a printing shell, a mounting frame, a motor, a rotating cylinder, gears, and a preheating component. The mounting frame is connected to the right side of the printing shell, and the motor is connected to the inner side of the right rear part of the printing shell. The upper and lower parts of the mounting frame are rotatably connected to the rotating cylinders, and gears are connected to the rear side of the rotating cylinders. The gears mesh with each other. The output shaft of the motor is connected to the upper rotating cylinder. The printing shell is provided with a preheating component that can preheat the paper.

[0007] Optionally, the preheating assembly includes a lead screw, a sliding frame, a mounting sleeve, a heating tube, and a mounting block. The lead screw is rotatably connected to the lower right part of the printing housing, and the sliding frame is threadedly connected to the lead screw. The sliding frame is slidably connected to the printing housing. The mounting sleeve is connected to the upper front part of the sliding frame. Mounting blocks are snapped into both the upper and lower parts of the mounting sleeve. Heating tubes are connected to the mounting blocks, and the heating tubes are located inside the rotating cylinder.

[0008] Optionally, a gripping block is provided on the front side of the lead screw.

[0009] Optionally, the motor, heating element, and processor are electrically connected via a control module.

[0010] Optionally, it also includes a fixing component, which includes a knob, a rotating frame, an elastic element, a connecting rod, and a limiting frame. The knob is rotatably connected to the front side of the middle of the mounting sleeve, and the rotating frame is connected to the rear side of the knob. An elastic element is connected between the rotating frame and the mounting sleeve. The left and right sides of the rotating frame are rotatably connected to the connecting rods, and the limiting frames are rotatably connected to the connecting rods. The limiting frames are all slidably connected to the mounting sleeve, and the limiting frames are all engaged with the adjacent mounting blocks.

[0011] Optionally, the elastic element is a torsion spring.

[0012] Compared with the prior art, the present invention has the following advantages: 1. The present invention moves the sliding frame and the mounting sleeve forward by rotating the lead screw, so that the heating tube moves forward and exits the rotating cylinder, which can be used to inspect the heating tube. When the heating tube needs to be replaced, the rotating frame is rotated by turning the knob, the torsion spring is deformed, and the connecting rod is rotated, so that the limiting frame moves away from the mounting block, and the heating tube can be replaced. This achieves the effect of quickly and conveniently inspecting or replacing the heating tube, and improving the equipment maintenance efficiency. 2. When the ambient temperature is low, this utility model heats the paper by heating the heating tube, and the heat is conducted to the paper through the rotating cylinder to preheat the paper, thereby avoiding the impact of low temperature environment on printing effect.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] A printer with a preheating structure, such as Figures 1-5 As shown, it includes a printing housing 1, a mounting bracket 2, a motor 3, a rotating cylinder 4, gears 5, and a preheating assembly. The mounting bracket 2 is connected to the right side of the printing housing 1, and the motor 3 is connected to the inner side of the right rear part of the printing housing 1. The rotating cylinder 4 is rotatably connected to both the upper and lower parts of the mounting bracket 2. Gears 5 are connected to the rear side of the rotating cylinder 4, and the gears 5 mesh with each other. The output shaft of the motor 3 is connected to the upper rotating cylinder 4. The printing housing 1 is equipped with a preheating assembly.

[0021] like Figures 1-5 As shown, the preheating assembly includes a lead screw 6, a sliding frame 7, a mounting sleeve 8, a heating tube 9, and a mounting block 10. The lead screw 6 is rotatably connected to the lower right part of the printing housing 1. A gripping block is provided on the front side of the lead screw 6 for easy gripping and rotation. The sliding frame 7 is threadedly connected to the lead screw 6 and is slidably connected to the printing housing 1. The mounting sleeve 8 is connected to the upper front part of the sliding frame 7. The mounting blocks 10 are snapped into both the upper and lower parts of the mounting sleeve 8. The heating tubes 9 are connected to the mounting blocks 10. The motor 3, the heating tubes 9, and the processor are electrically connected through a control module. The heating tubes 9 are located inside the rotating cylinder 4.

[0022] like Figure 1 , Figure 4 and Figure 5As shown, it also includes a fixing component, which includes a knob 11, a rotating frame 12, an elastic element, a connecting rod 14, and a limiting frame 15. The knob 11 is rotatably connected to the front side of the middle of the mounting sleeve 8, and the rotating frame 12 is connected to the rear side of the knob 11. An elastic element, which is a torsion spring 13, is connected between the rotating frame 12 and the mounting sleeve 8. The connecting rod 14 is rotatably connected to both the left and right sides of the rotating frame 12, and the limiting frame 15 is rotatably connected to both connecting rods 14. The limiting frame 15 is slidably connected to the mounting sleeve 8 and is engaged with the adjacent mounting block 10.

[0023] When using this utility model, first place the printing housing 1 in the printing area. When printing is required, put the paper into the mounting frame 2 so that the paper is located between the rotating cylinders 4. The processor starts the motor 3 through the control module, which drives the upper rotating cylinder 4 to rotate. The gear 5 meshes and moves, causing the lower rotating cylinder 4 to rotate, and the paper is transported into the printing housing 1 for printing. When the ambient temperature is low, the heating tube 9 is heated, and the heat is conducted to the paper through the rotating cylinder 4 to preheat the paper. This can prevent the low temperature environment from affecting the printing effect. The preheating temperature should be much lower than the thermal paper color change temperature to avoid damaging the subsequent printing effect. When the heating tube 9 needs to be inspected, rotate the screw 6 to move the sliding frame 7 and the mounting sleeve 8 forward, causing the heating tube 9 to move forward and exit the rotating cylinder 4 for easy inspection. When the heating tube 9 needs to be replaced, rotate the rotating frame 12 by turning the knob 11. The torsion spring 13 deforms, causing the connecting rod 14 to rotate, causing the limiting frame 15 to move away from the mounting block 10. The mounting block 10 can then be removed from the mounting sleeve 8 to replace the heating tube 9. After replacement, release the knob 11. The torsion spring 13 returns to its original position, causing the rotating frame 12 to rotate back to its original position. The connecting rod 14 rotates, causing the limiting frame 15 to return to its original position and re-engage with the mounting block 10, fixing the mounting block 10 onto the mounting sleeve 8. This allows for quick and convenient inspection or replacement of the heating tube 9, improving equipment maintenance efficiency.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
