[0025] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0026] like Figure 1 and Figure 2 As shown, a heating and dust removal device for a printing device is provided, comprising a frame 1, on which a conveyor line 2 for conveying a sheet a is disposed, and the characteristic is that a heating and dust removal mechanism 3 for heating, dust removal or foreign matter removal of the sheet a on the conveyor line 2 is disposed on the frame 1, and the heating and dust removal mechanism 3 comprises a hot air blower 301 and a connecting pipe assembly 302 connected to the hot air blower 301, the connecting pipe assembly 302 is disposed on the frame 1 and corresponding to the sheet a, and the hot air generated by the hot air blower 301 when working is blown onto the sheet a through the connecting pipe assembly 302.

[0027] Specifically, by providing a heating dust removal mechanism 3 on the frame 1, the heating dust removal mechanism 3 can pre-treat the sheet a on the conveyor line 2 before printing by blowing hot air to remove possible dust, dirt and other foreign matter, thereby reducing the occurrence of defective products. In addition, the heating dust removal mechanism 3 can also soften the sheet a and improve its affinity for ink. After heating, the molecular activity on the surface of the sheet a increases, the attraction between molecules decreases, and it is easier to absorb ink. In this way, the pressure required in the printing process is also reduced accordingly, which improves the printing efficiency, thereby greatly improving the quality and consistency of the printed product.

[0028] Further, if Figure 3 and Figure 4 As shown, the connecting pipe assembly 302 includes an air outlet pipe 3021 , and a plurality of air outlet holes 3021 b are arranged on the outer circumference of the air outlet pipe 3021 , and the plurality of air outlet holes 3021 b are evenly spaced.

[0029] Specifically, the provision of multiple air outlet holes 3021b allows hot air to be evenly blown to sheet a, thereby blowing away dust, dirt and other foreign matter on sheet a, and also allows the gas to flow more evenly throughout the pipeline, thereby improving the efficiency of gas exchange.

[0030] Further, if Figure 3 and Figure 4As shown, a hot air outlet is provided on the hot air blower 301, and the connecting pipe assembly 302 also includes an output pipe 3022, one end of the output pipe 3022 is connected to the hot air outlet, and the other end of the output pipe 3022 is connected to the outlet pipe 3021, and the hot air is discharged from the outlet hole 3021b on the outlet pipe 3021 along the output pipe 3022.

[0031] Specifically, the hot air from the hot air blower 301 will be connected through the output pipe 3022 in the connecting pipe assembly 302 and the air outlet pipe 3021b in the connecting pipe assembly 302, and finally discharged from the air outlet hole 3021b in the air outlet pipe 3021b, thereby realizing the discharge of the hot air; such a design allows the hot air to flow and be transmitted efficiently in the pipeline, thereby improving the energy efficiency and stability of the system.

[0032] It should be noted that the output tube 3022 is made of nylon.

[0033] Further, if Figure 3 and Figure 4 As shown, a connecting valve 3023 is provided between the output pipe 3022 and the air outlet pipe 3021 .

[0034] Specifically, a connection valve 3023 is provided on one end of the outlet pipe 3021, and the other end of the output pipe 3022 cooperates with the connection valve 3023, so that the output pipe 3022 is connected to the outlet pipe 3021, and the connection and cooperation are convenient;

[0035] It should be noted that the other end of the air outlet pipe 3021 is a closed opening, so that the hot air can only be discharged from the air outlet 3021b.

[0036] Further, if Figure 2 As shown, the length of the air outlet pipe 3021 is equivalent to the width of the conveying line 2.

[0037] Specifically, the air outlet pipe 3021 is placed horizontally on the conveyor line 2, and the length of the air outlet pipe 3021 is greater than or equal to the width of the conveyor line 2, so that the hot air blown out by the air outlet pipe 3021 can remove dust, dirt and other foreign matter on the sheet a.

[0038] Further, if Figure 3-Figure 5 As shown, the heating dust removal mechanism 3 also includes a bracket assembly 303, and the air outlet pipe 3021 is fixedly installed on the frame 1 through the bracket assembly 303 and the direction of the air outlet hole 3021b can be adjusted.

[0039] Specifically, the air pipe 3021b can adjust the direction of the air outlet 3021b through the adjustment of the bracket assembly 303. This not only facilitates the maintenance and cleaning of the air outlet pipe 3021b, but also can flexibly adjust the direction of the air outlet 3021b according to different working environments during actual use to achieve the best dust removal effect. Such a design not only ensures the continuity and stability of production, but also improves work efficiency.

[0040] Further, if Figure 3-Figure 5 As shown, the support assembly 303 includes a support fixing seat 3031 and a trachea fixing seat 3032. The support fixing seat 3031 is provided with a vertically arranged fixing portion 3031c, and one end of the trachea fixing seat 3032 can be inserted into the fixing portion 3031c.

[0041] Specifically, the trachea fixing seat 3032 can be inserted into the fixing portion 3031 c to facilitate the disassembly and installation of the trachea fixing seat 3032 and the bracket fixing seat 3031 .

[0042] Furthermore, a positioning portion 3032d cooperating with the air outlet pipe 3021 is provided on the other end of the air pipe fixing seat 3032 , and the air outlet pipe 3021 can be rotated on the positioning portion 3032d to realize that the air outlet hole 3021b is set toward the direction of the conveying line 2 .

[0043] Specifically, the other end of the air pipe fixing seat 3032 is indeed provided with a positioning portion 3032d that cooperates with the air outlet pipe 3021. This design allows the air outlet pipe 3021 to rotate at a fixed position to achieve the purpose of changing the direction of the air outlet hole 3021b toward the conveyor line 2. Such a design can not only achieve more efficient work under different working conditions, but also help to improve the degree of automation of the system and reduce the cost of manual intervention.

[0044] Further, if Figure 5 As shown, a positioning hole 3032e is provided on the positioning portion 3032d, and a screw passes through the positioning hole 3032e to fix the air outlet pipe 3021 on the positioning portion 3032d.

[0045] Specifically, the presence of the positioning hole 3032e ensures that after the air outlet pipe 3021 is rotated to a suitable position, it is prevented from being displaced during operation. Therefore, it is fixed on the positioning portion 3032d by screws.

[0046] Furthermore, the hot air blower 301 is provided with an air inlet, a heating component and a fan component. When the fan component is working, the outside air enters from the air inlet and flows through the heating component to be heated to form hot air, and then blown to the connecting pipe component 302.

[0047] Specifically, through the cooperation of the air inlet, the heating assembly and the fan assembly, the processed air is evenly blown to the connecting pipe assembly 302 .
