Technical Field
[0001] This utility model relates to the field of high-speed laser printer technology, and specifically to a novel heating roller that facilitates heat dissipation. Background Technology
[0002] High-speed laser printers are precision devices integrating optics, mechanics, and electronics. Their printing speed is generally between 130 and 300 ppm. They are mainly used in production fields such as small-batch printing and bill printing for banks and insurance companies. They are widely used in offices, homes, educational institutions, and enterprises. For example, laser printers can quickly print large quantities of test papers, lesson plans, and other educational resources. Departments such as finance, human resources, and marketing in enterprises have high requirements for printing speed and quality, and laser printers can meet these needs perfectly.
[0003] The heating roller, also known as the fuser or thermal roller, is a crucial component in high-speed laser printers. Its main function is to heat and conduct heat, melting and fixing the toner on the paper. This is a key step in ensuring print quality. Through the action of the heating roller, laser printers can print clearer and more durable images and text. As a critical component for print quality, the heating roller of a high-speed laser printer requires regular maintenance and upkeep to ensure its proper functioning and extend its lifespan.
[0004] In industrial production, heating rollers generate a large amount of heat during operation. If the heat cannot be dissipated in time, the temperature of the heating roller will become too high, which will affect the print quality and the lifespan of the printer. Therefore, the heat dissipation problem of heating rollers is particularly important. Existing heating rollers usually dissipate heat naturally through heat exchange between their metal material and the surrounding environment. However, this heat dissipation method is inefficient and cannot meet the needs of high-speed and high-load printing. Therefore, it is necessary to propose a new type of heating roller that is easy to dissipate heat to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a new type of heating roller that facilitates heat dissipation, in order to solve the problem that existing heating rollers usually dissipate heat naturally through heat exchange between their metal material and the surrounding environment. However, this heat dissipation method is inefficient and cannot meet the needs of high-speed, high-load printing.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0007] A novel heat dissipation-friendly heating roller includes a heating roller body; a cooling pipe is fixedly installed inside the heating roller body; a fixing pipe is fixedly installed on one side of the heating roller body; a first bearing is fixedly connected to the outer surface of the fixing pipe; a water inlet pipe is fixedly connected to one side of the fixing pipe; a connecting pipe is fixedly installed on the other side of the heating roller body; a second bearing is fixedly connected to the outer surface of the connecting pipe; a drain pipe is fixedly connected to the other side of the connecting pipe; and a heating layer is provided on the inner wall of the heating roller body surrounding the cooling pipe.
[0008] The above-mentioned technical solution involves the existing heating rollers, which typically dissipate heat naturally through heat exchange between their metal material and the surrounding environment. However, this heat dissipation method is inefficient and cannot meet the demands of high-speed, high-volume printing. In this application, by opening a cavity inside the heating roller body, the heat dissipation area can be increased, thereby accelerating heat dissipation and achieving a heat dissipation effect. Furthermore, by installing cooling pipes, water inlet pipes, and drain pipes, and by fixing the cooling pipes to the inner wall of the heating roller body, cooling water can enter the interior of the cooling pipes through the water inlet pipes and then exit through the drain pipes, thereby carrying away the heat from the surface of the heating roller body and achieving a cooling effect on the heating roller body, thus improving the heat dissipation effect of the heating roller body.
[0009] A further improvement of the present invention is that: a number of first heat-conducting plates are fixedly installed inside the heating roller body, each first heat-conducting plate is offset from the cooling pipe, and the bottom surface of each first heat-conducting plate is fixedly connected to the inner wall of the heating roller body.
[0010] In the above-mentioned technical solution, the contact area between the heating roller body and the cooling pipe is limited, and the heat dissipation effect is relatively insufficient at the position where the inner wall of the heating roller body does not contact the cooling pipe. In this application, by installing a first heat-conducting plate, the first heat-conducting plate can absorb the heat on the surface of the heating roller body by tightly attaching the first heat-conducting plate to the surface of the heating roller body, so as to guide the heat away from the surface of the heating roller body.
[0011] A further improvement of this utility model is that a first heat transfer plate is fixedly installed on the top of each first heat conduction plate, and each first heat transfer plate is fixedly connected to the outer surface of the cooling pipe.
[0012] In the above technical solution, by installing a first heat transfer plate, which is attached to the surface of the cooling pipe, the heat carried out by the first heat transfer plate can be transferred to the surface of the cooling pipe, thereby transferring the heat out from the inside of the heating roller body, thus expanding the cooling range of the heating roller body surface, so as to facilitate heat dissipation treatment of the heating roller body.
[0013] A further improvement of this utility model is that each first heat-conducting plate is made of copper.
[0014] By adopting the above technical solution, the thermal conductivity of the first heat-conducting plate can be improved by using copper material, thereby improving the heat dissipation effect on the surface of the heating roller body.
[0015] A further improvement of this utility model is that: a second heat-conducting plate is fixedly installed inside the heating roller body at the top of each first heat transfer plate, each second heat-conducting plate is offset from the cooling pipe, and the surface of the top of each second heat-conducting plate is fixedly connected to the inner wall of the heating roller body.
[0016] In the above-mentioned technical solution, the contact area between the heating roller body and the cooling pipe is limited, and the heat dissipation effect is relatively insufficient at the position where the inner wall of the heating roller body does not contact the cooling pipe. In this application, by installing a second heat-conducting plate, the second heat-conducting plate can absorb the heat on the surface of the heating roller body by tightly attaching the second heat-conducting plate to the surface of the heating roller body, so as to guide the heat away from the surface of the heating roller body.
[0017] A further improvement of this utility model is that a second heat transfer plate is fixedly installed at the bottom of each second heat conduction plate, and each second heat transfer plate is fixedly connected to the outer surface of the cooling pipe.
[0018] In the above technical solution, by installing a second heat transfer plate, which is attached to the surface of the cooling pipe, heat can be transferred to the surface of the cooling pipe, and then the heat can be transferred out from the inside of the heating roller body, thereby expanding the cooling range of the heating roller body surface and facilitating heat dissipation treatment of the heating roller body.
[0019] A further improvement of this utility model is that each second heat-conducting plate is made of copper.
[0020] By adopting the above technical solution, the thermal conductivity of the first and second heat-conducting plates can be improved by using copper material for the second heat-conducting plate, thereby improving the heat dissipation effect on the surface of the heating roller body.
[0021] A further improvement of this utility model is that a fixing frame is provided inside the heating roller body on the inner side of each cooling pipe, and the bottom surface of each second heat transfer plate and the top surface of each first heat conduction plate are fixedly connected to the surface of the fixing frame.
[0022] By adopting the above technical solution, the second heat transfer plate and the first heat transfer plate can be connected and fixed by the mounting bracket, thereby improving the overall structural strength of the first heat conduction plate and the second heat conduction plate, as well as the second heat transfer plate and the first heat transfer plate. This, in turn, improves the internal structural strength of the heating roller body, reduces the possibility of deformation of the heating roller body, and improves the performance of the heating roller body.
[0023] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0024] 1. This utility model provides a novel heating roller that facilitates heat dissipation. By opening a cavity inside the heating roller body, the heat dissipation area can be increased, thereby accelerating the dissipation of heat and achieving a heat dissipation effect. Furthermore, through the cooperation between the cooling pipe, the water inlet pipe, and the drain pipe, in particular, by fixing the cooling pipe to the inner wall of the heating roller body, the cooling water can carry away the heat on the surface of the heating roller body during the process of flowing through the water inlet pipe and the drain pipe, thereby achieving the cooling treatment of the heating roller body and improving the heat dissipation effect of the heating roller body.
[0025] 2. This utility model provides a novel heating roller that facilitates heat dissipation. By attaching and fixing the first heat-conducting plate and the second heat-conducting plate to the surface of the heating roller body, the heat on the surface of the heating roller body can be absorbed and transferred to the first heat-conducting plate and the second heat-conducting plate. Furthermore, by attaching and fixing the first heat-conducting plate and the second heat-conducting plate to the surface of the cooling pipe, the heat can be transferred to the surface of the cooling pipe, so as to facilitate the transfer of more heat from the inside of the heating roller body, thereby expanding the cooling range of the surface of the heating roller body and further improving the heat dissipation effect of the surface of the heating roller body.
[0026] 3. This utility model provides a novel heating roller that facilitates heat dissipation. By installing a fixing frame, the second heat transfer plate and the first heat transfer plate can be connected and fixed, thereby improving the overall structural strength of the first heat conduction plate, the second heat conduction plate, the second heat transfer plate, and the first heat transfer plate. It can also support and limit the cavity inside the heating roller body to a certain extent, thereby improving the internal structural strength of the heating roller body, reducing the possibility of deformation of the heating roller body, and improving the performance of the heating roller body.

[0035] The present invention will be further described in detail below with reference to embodiments:
[0036] Example 1
[0037] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a novel heating roller that facilitates heat dissipation, including a heating roller body 1; a cooling pipe 2 is fixedly installed inside the heating roller body 1, a fixing pipe 7 is fixedly installed on one side of the heating roller body 1, a first bearing 11 is fixedly connected to the outer surface of the fixing pipe 7, a water inlet pipe 8 is fixedly connected to one side of the fixing pipe 7, a connecting pipe 9 is fixedly installed on the other side of the heating roller body 1, a second bearing 12 is fixedly connected to the outer surface of the connecting pipe 9, a drain pipe 10 is fixedly connected to the other side of the connecting pipe 9, and a heating layer 14 is provided on the inner wall of the heating roller body 1 surrounding the cooling pipe 2.
[0038] In this embodiment, conventional heating rollers typically dissipate heat naturally through heat exchange between their metal material and the surrounding environment. However, this heat dissipation method is inefficient and cannot meet the demands of high-speed, high-load printing. In this application, by opening a cavity inside the heating roller body 1, the heat dissipation area can be increased, thereby accelerating heat dissipation and achieving a heat dissipation effect. Furthermore, by installing a cooling pipe 2, a water inlet pipe 8, and a drain pipe 10, wherein the cooling pipe 2 is fixedly attached to the inner wall of the heating roller body 1, and cooling water enters the interior of the cooling pipe 2 through the water inlet pipe 8 and then exits through the drain pipe 10, the heat on the surface of the heating roller body 1 can be carried away, thereby achieving a cooling treatment of the heating roller body 1 and improving the heat dissipation effect of the heating roller body 1.
[0039] Example 2
[0040] like Figure 2 , Figure 5 and Figure 6As shown, based on Embodiment 1, this utility model provides the following technical solution: Preferably, a plurality of first heat-conducting plates 3 are fixedly installed inside the heating roller body 1. Each first heat-conducting plate 3 is offset from the cooling pipe 2. The bottom surface of each first heat-conducting plate 3 is fixedly connected to the inner wall of the heating roller body 1. A first heat transfer plate 4 is fixedly installed on the top of each first heat-conducting plate 3. Each first heat transfer plate 4 is fixedly connected to the outer surface of the cooling pipe 2. Each first heat-conducting plate 3 is made of copper. A second heat-conducting plate 5 is fixedly installed inside the heating roller body 1 at the top of each first heat transfer plate 4. Each second heat-conducting plate 5 is offset from the cooling pipe 2. The top surface of each second heat-conducting plate 5 is fixedly connected to the inner wall of the heating roller body 1. A second heat transfer plate 6 is fixedly installed on the bottom of each second heat-conducting plate 5. Each second heat transfer plate 6 is fixedly connected to the outer surface of the cooling pipe 2. Each second heat-conducting plate 5 is made of copper.
[0041] In this embodiment, the contact area between the heating roller body 1 and the cooling pipe 2 is limited. The heat dissipation effect is relatively insufficient at the position on the inner wall of the heating roller body 1 that is not in contact with the cooling pipe 2. In this application, by installing a first heat-conducting plate 3 and a second heat-conducting plate 5, and by tightly attaching the first heat-conducting plate 3 and the second heat-conducting plate 5 to the surface of the heating roller body 1, the first heat-conducting plate 3 and the second heat-conducting plate 5 can absorb the heat on the surface of the heating roller body 1 and transfer the heat to the first heat-transfer plate 4 and the second heat-transfer plate 6. By attaching the first heat-transfer plate 4 and the second heat-transfer plate 6 to the surface of the cooling pipe 2, the heat can be transferred to the surface of the cooling pipe 2, and then the heat can be transferred out from the inside of the heating roller body 1, thereby expanding the cooling range of the surface of the heating roller body 1, so as to facilitate the heat dissipation treatment of the heating roller body 1. By using copper material for the first heat-conducting plate 3 and the second heat-conducting plate 5, the thermal conductivity of the first heat-conducting plate 3 and the second heat-conducting plate 5 can be improved, thereby improving the heat dissipation effect on the surface of the heating roller body 1.

[0044] In this embodiment, the second heat transfer plate 6 and the first heat transfer plate 4 can be connected and fixed by the mounting bracket 13, thereby improving the overall structural strength of the first heat conduction plate 3 and the second heat conduction plate 5, the second heat transfer plate 6 and the first heat transfer plate 4, and thus improving the internal structural strength of the heating roller body 1, reducing the possibility of deformation of the heating roller body 1, and improving the performance of the heating roller body 1.
[0045] The working principle of this new type of heating roller that facilitates heat dissipation is explained in detail below.
[0046] like Figures 1-6 As shown, after the heating roller body 1 is used, the operator can connect the water inlet pipe 8 and the drain pipe 10 to the external water supply and drainage structure, so that external cooling water can enter the interior of the cooling pipe 2 through the water inlet pipe 8 and the fixed pipe 7. The heat generated by the contact between the cooling pipe 2 and the surface of the heating roller body 1 can flow to the other side with the cooling pipe 2. The first heat-conducting plate 3 and the second heat-conducting plate 5 can guide some of the heat to the first heat transfer plate 4 and the second heat transfer plate 6 respectively, and then guide it to the surface of the cooling pipe 2, and continue to flow to the other side with the cooling pipe 2. Finally, the heat can be discharged through the connecting pipe 9 and the drain pipe 10 to achieve the cooling treatment of the heating roller body 1, which facilitates the heat dissipation treatment of the heating roller body 1.

Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
