[0034] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] Example 1:

[0036] like Figure 1 As shown, the preheating plate in this embodiment includes an aluminum plate body 1, an electric heating element 2, and an elastic clamping element 3. (Refer to...) Figure 2 and Figure 3 One side of the plate 1 is machined with a preheating surface 14, and the other side of the plate 1 is machined with three mounting positions 11 for mounting the electric heating element 2. A first slot 12 and a second slot 13 are machined on both sides of the mounting positions 11 on the plate 1, respectively. The electric heating element 2 is detachably mounted on the mounting position 11, and the elastic clamping member 3 is detachably mounted on the plate 1, pressing the electric heating element 2 firmly into the mounting position 11.

[0037] Reference Figure 4 and Figure 5 The elastic clamping member 3 has a concave elastic clamping portion 31, which is semi-circular in shape. A first locking foot 32 and a second locking foot 33 are respectively machined on both sides of the elastic clamping portion 31. The lower end of the first locking foot 32 has a protruding first locking edge 34, and the lower end of the second locking foot 33 has a protruding second locking edge 35. A first horizontal connecting portion 36 is machined between the first locking foot 32 and the elastic clamping portion 31. One side of the first horizontal connecting portion 36 connects to one side of the elastic clamping portion 31, and the other side connects to the first locking foot 32. A second horizontal connecting portion 37 is machined between the second locking foot 33 and the elastic clamping portion 31. One side of the second horizontal connecting portion 37 connects to one side of the elastic clamping portion 31, and the other side connects to the second locking foot 33. Preferably, the thickness of the elastic clamping member 3 is 1mm. When the elastic clamping member 3 is in its natural state, such as... Figure 4 As shown, the angle between the first locking foot 32 and the first horizontal connecting part 36 is 93°, and the angle between the second locking foot 33 and the second horizontal connecting part 37 is also 93°. The lower end of the first locking foot 32 of the elastic pressing member 3 extends outward at an angle, and the lower end of the second locking foot 33 of the elastic pressing member 3 also extends outward at an angle.

[0038] Reference Figure 6 The electric heating component 2 includes an electric heating plate 22 and a heat-conducting plate 21 made of copper. The two electric heating plates 22 are attached to the top surface of the heat-conducting plate 21 with thermally conductive adhesive, and the electric heating plate 22 and the heat-conducting plate 21 are fixed together.

[0039] The electric heating element 2 is placed in the mounting position 11, with the bottom surface of the heat-conducting plate 21 fitting against the bottom surface of the mounting position 1. The first locking edge 34 of the elastic clamping member 3 engages with the first locking groove 12, and the second locking edge 35 of the elastic clamping member 3 engages with the second locking groove 13, thereby installing the elastic clamping member 3 onto the plate 1. At this time, the elastic clamping part 31 presses against the heat-conducting plate 21 of the electric heating element 2, thereby fixing the electric heating element 2 to the mounting position 11. Figure 1 As shown, the bottom surface of the heat-conducting plate 21 is attached to the plate body 1. An elastic clamping element 3 is provided at each end of the heat-conducting plate 21 on the plate body 1 to clamp the electric heating assembly 2, as shown. Figure 7 As stated above.

[0040] The principle of removing the elastic clamping element 3 from the plate 1 is as follows: (Refer to...) Figure 8 ,along Figure 8 Applying pressure to the second locking foot 32 of the elastic clamping member 3 in the direction of arrow A causes the second locking foot 32 to disengage from the second locking groove 13, at which point the elastic clamping member 3 can be removed. Similarly, applying pressure to the first locking foot 32 causes the first locking foot 32 to disengage from the first locking groove 12, which also allows the elastic clamping member 3 to be removed.

[0041] Example 2:

[0042] The preheating plate in this embodiment differs from the preheating plate in Embodiment 1 in that: (Refer to...) Figure 9 The bottom of the mounting position 11 of the plate 1 is machined with a concave arc-shaped groove 111, which extends along the length of the plate 1. (Refer to...) Figure 10 The bottom of the heat-conducting plate 21 of the electric heating component 2 is machined with an outwardly convex arc-shaped portion 211, which extends along the length of the heat-conducting plate 21. When the electric heating component 2 is installed in the mounting position 11, the arc-shaped portion 211 of the heat-conducting plate 21 mates with the arc-shaped groove 111 of the mounting position 11, such as... Figure 11 As shown, the heat-conducting plate 21 is arc-shaped to the plate body 1, which increases the contact area between the heat-conducting plate 21 and the plate body 1 and improves the heat conduction efficiency between the heat-conducting plate 21 and the plate body 1.

[0043] The principle of assembly and disassembly of the electric heating component 2 of the preheating plate of this utility model is as follows: During normal use, the elastic clamping part 31 of the elastic clamping member 3 securely fixes the electric heating component 2 to the plate body 1. At this time, if Figure 1As shown, ensure good heat conduction between the electric heating assembly 2 and the plate body 1. The heat generated by the electric heating plate 22 is quickly transmitted to the plate body 1 through the heat-conducting plate 21, and then the components or printing media that need to be preheated are heated, such as preheating the printing media (paper, labels, etc.) of the printer. When the electric heating assembly 2 needs to be repaired and replaced, the elastic pressing piece 3 is disassembled, the pressure of the elastic pressing piece 3 on the electric heating assembly 2 is released, the electric heating assembly 2 and the plate body 1 can be separated, and the repair operation is completed. After the repair operation is completed, the new electric heating assembly 2 is placed in the installation position 11, the elastic pressing piece 3 is installed on the plate body 1, the electric heating assembly 2 is pressed and fixed by the elastic pressing piece 3, and the preheating plate restores the normal use function.

[0044] Compared with the prior art, the preheating plate of the utility model adopts the detachable elastic pressing piece to press and fix the electric heating assembly, realizes the detachable electric heating assembly and the plate body. When the electric heating plate is damaged, only the electric heating assembly needs to be replaced, avoiding the scrapping of the entire preheating plate, greatly reducing the resource waste; reducing the maintenance and use cost of the printer, the user does not need to bear the high overall replacement cost, reducing the economic burden. In addition, reducing the scrapping amount of the preheating plate plays a positive role in environmental protection, in line with the concept of sustainable development. In addition, the disassembly and assembly of the elastic pressing piece are also convenient and fast, improving the disassembly and assembly efficiency.

[0045] The above only describes the preferred embodiment of the utility model, and does not limit the utility model, any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
