Description
Technical Field
[0001] The utility model relates to the technical field of high-speed laser printers, in particular to a heating roller with a uniform high heat conductivity function. Background Art
[0002] A high-speed laser printer is a highly efficient printing device. Its print engine has a higher rotation speed and processing power. Its photosensitive drum rotates faster and can complete more imaging cycles per unit time. It is equipped with high-speed data transmission interfaces, such as USB 3.0 and Ethernet interfaces, which can quickly receive print data. At the same time, the internal processor performance is also very strong, which can quickly process print instructions and convert data into control signals for laser emission, reducing the waiting time for printing tasks.
[0003] The heating roller is a key component in the fusing system of high-speed laser printers. During the laser printing process, the toner image on the printing paper needs to go through the fusing process before it can be firmly attached to the paper. The heating roller plays a core role in this process. It is a metal roller with an internal heating device, usually made of metal such as aluminum, with a special coating on the surface, such as polytetrafluoroethylene coating, to prevent toner from sticking and provide good wear resistance.
[0004] There is a heating element inside the heating roller, and halogen lamps or ceramic heating elements are commonly used. When the printer starts working, current passes through these heating elements, and the heating elements generate heat. This heat is transferred to the metal shell of the heating roller through thermal radiation. However, when the heating element transfers heat to the heating roller through thermal radiation, the heat will radiate in all directions, and only a part of it can reach the surface of the heating roller. This results in a relatively low proportion of effective heat actually transferred to the heating roller for heating, which easily leads to insufficient and uneven thermal conductivity of the heating roller. Therefore, it is necessary to propose a heating roller with uniform high thermal conductivity to solve the above problems. Utility Model Content
[0005] The purpose of the utility model is to provide a heating roller with uniform high thermal conductivity, so as to solve the problem that when the heat generated by the heating element inside the existing heating roller is transferred to the heating roller through thermal radiation, the heat will be dissipated in all directions, and only a part of it can be irradiated to the surface of the heating roller. This results in a relatively low proportion of effective heat actually transferred to the heating roller for heating, which easily leads to insufficient thermal conductivity of the heating roller and unevenness.
[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:
[0007] The top surface of each guide plate is fixedly connected to the inner wall of the heating roller body, and each guide plate is inclined toward the bottom of one side. The bottom surface of each guide plate is fixedly connected to the inner wall of the heating roller body, and each guide plate is inclined toward the top of the other side. The bottom surface of each guide plate at both ends of the heating tube is fixedly connected to the surface of each fixed plate, and a plurality of connecting plates are fixedly installed on the top of the heating tube, and each connecting plate is staggered with each guide plate, and the top surface of each connecting plate is fixedly connected to the inner wall of the heating roller body, and each connecting plate is inclined toward the top of one side. The bottom of each connecting plate outside the heating tube is fixedly installed with a guide plate, and the bottom surface of each guide plate is spaced a certain distance from the inner wall of the heating roller body, and each guide plate is inclined toward the bottom of the other side.
[0008] The above technical solution is adopted. In this solution, when the existing heating roller is in use, when the heating element transfers heat to the heating roller through thermal radiation, the heat will be dissipated in all directions, and only a portion can be irradiated to the surface of the heating roller. This results in a relatively low proportion of effective heat actually transferred to the heating roller for heating, which can easily lead to insufficient and uneven heat conduction effect of the heating roller. In the present application, by installing a fixing plate and a guide plate, the heat dissipation direction emitted by the heating tubes near their positions can be guided respectively. By installing a connecting plate and a guide plate, the heat dissipation direction emitted by the heating tubes near their positions can be guided respectively, thereby accelerating the speed at which heat reaches the inner wall of the heating roller body and reducing the possibility of heat loss, thereby ensuring that the heat fully contacts the surface of the heating roller body and heats the heating roller body, thereby improving the heat conduction effect. In addition, by setting a certain distance between the guide plate and the guide plate and the inner wall surface of the heating roller body, and by arranging the fixing plate and the guide plate as well as the connecting plate and the guide plate at an angle, the possibility of them affecting the heat flow is reduced, thereby facilitating the flow of heat inside the heating roller body, thereby ensuring that the heat is evenly distributed inside the heating roller body and making the heat conduction more uniform.
[0009] A further improvement of the technical solution of the present utility model is that first heat sinks are fixedly mounted on both side surfaces of each fixing plate.
[0010] The above-mentioned technical solution is adopted. In this solution, only the fixed plate and the guide plate are set, and their positions are fixed. The heat emitted from the surface of the heating tube far away from the fixed plate and the guide plate is still not easy to dissipate, which affects the thermal conductivity of the heating roller body to a certain extent. In this application, by installing the first heat sink, the heat of the heating tube adsorbed on the surface of the fixed plate can be dissipated to both sides, which can improve the temperature distribution of the heating roller body, further improve the uniformity of heat distribution inside the heating roller body, and improve the thermal conductivity effect.
[0011] A further improvement of the technical solution of the present invention is that second heat sinks are fixedly connected to both side surfaces of each guide plate.
[0012] By adopting the above technical solution, in this solution, by installing a second heat sink, the heat adsorbed by the heating tube on the surface of the guide plate can be dissipated to both sides, which can improve the temperature distribution of the heating roller body, further improve the uniformity of heat distribution inside the heating roller body, and improve the thermal conductivity effect.
[0013] A further improvement of the technical solution of the present utility model is that the material of each fixing plate and each guide plate is aluminum alloy.
[0014] The above technical solution is adopted. In this solution, the fixing plate and the guide plate are made of aluminum alloy material, wherein the aluminum alloy material has high thermal conductivity and good thermal conductivity, so it can transfer heat more effectively, thereby further improving the thermal conductivity effect of the heating roller body.
[0015] A further improvement of the technical solution of the present invention is that third heat sinks are fixedly mounted on both side surfaces of each connecting plate.
[0016] The above-mentioned technical solution is adopted. In this solution, only the connecting plate and the guide plate are set, and their positions are fixed. The heat emitted from the surface of the heating tube far away from the connecting plate and the guide plate is still not easy to dissipate, which affects the thermal conductivity of the heating roller body to a certain extent. In this application, by installing a third heat sink, the heat of the heating tube adsorbed on the surface of the connecting plate can be dissipated to both sides, which can improve the temperature distribution of the heating roller body, further improve the uniformity of heat distribution inside the heating roller body, and improve the thermal conductivity effect.
[0017] A further improvement of the technical solution of the present invention is that fourth heat sinks are fixedly mounted on both side surfaces of each guide plate.
[0018] By adopting the above technical solution, in this solution, by installing a fourth heat sink, the heat adsorbed by the heating tube on the surface of the guide plate can be dissipated to both sides, which can improve the temperature distribution of the heating roller body, further improve the uniformity of heat distribution inside the heating roller body, and improve the thermal conductivity effect.
[0019] A further improvement of the technical solution of the present utility model is that the material of each connecting plate and each guide plate is aluminum alloy.
[0020] The above technical solution is adopted. In this solution, the connecting plate and the guide plate are made of aluminum alloy material, wherein the aluminum alloy material has high thermal conductivity and good thermal conductivity, so it can transfer heat more effectively, thereby further improving the thermal conductivity effect of the heating roller body.
[0021] Due to the adoption of the above technical solution, the present invention has achieved the following technical advancements compared to the prior art:
[0022] 1. The utility model provides a heating roller with uniform high thermal conductivity. By installing a fixing plate and a guide plate as well as a connecting plate and a guide plate, the heat dissipation direction of the heating tubes near these positions can be guided respectively, thereby accelerating the speed at which the heat reaches the inner wall of the heating roller body, so as to ensure that the heat fully contacts the surface of the heating roller body, thereby reducing the possibility of heat loss and improving the heat conduction effect. By setting a certain distance between the guide plate and the guide plate and the inner wall surface of the heating roller body, and by arranging the fixing plate and the guide plate as well as the connecting plate and the guide plate at an angle, it is possible to facilitate the flow of heat inside the heating roller body, thereby ensuring that the heat is evenly distributed inside the heating roller body, making the heat conduction more uniform.
[0023] 2. The utility model provides a heating roller with uniform high thermal conductivity.

[0033] The present invention is further described in detail below with reference to the embodiments:
[0034] Example 1
[0035] like Figure 1 、 Figure 2 and Figure 3 As shown, the utility model provides a heating roller with uniform high thermal conductivity, including a heating roller body 1; a heating tube 2 is fixedly installed inside the heating roller body 1, and a plurality of fixing plates 3 are fixedly installed at the bottom of the heating tube 2, and the bottom surface of each fixing plate 3 is fixedly connected to the inner wall of the heating roller body 1, and each fixing plate 3 is in a state of being inclined to the bottom of one side, and a plurality of guide plates 4 are fixedly installed on the top of the heating tube 2, and the top surface of each guide plate 4 is at a certain distance from the inner wall of the heating tube 2, and each guide plate 4 is in a state of being inclined to the top of the other side, and the two sides of the heating tube 2 are fixedly installed.

The bottom surface of each guide plate 6 is at a certain distance from the inner wall of the heating roller body 1, and each guide plate 6 is inclined to the bottom of the other side.
[0036] In this embodiment, when the existing heating roller is in use, when the heating element transfers heat to the heating roller through thermal radiation, the heat will be dissipated in all directions, and only a part of it can be irradiated to the surface of the heating roller. This results in a relatively low proportion of effective heat actually transferred to the heating roller for heating, which easily leads to insufficient and uneven heat conduction effect of the heating roller. In this application, by installing the fixing plate 3 and the guide plate 4, the heat dissipation direction of the heating tube 2 near their position can be guided respectively, and by installing the connecting plate 5 and the guide plate 6, the heat dissipation direction of the heating tube 2 near their position can be guided respectively. , speeding up the speed at which heat reaches the inner wall of the heating roller main body 1, and reducing the possibility of heat loss, to ensure that the heat fully contacts the surface of the heating roller main body 1, and heats the heating roller main body 1, thereby improving the heat conduction effect, and by setting a certain distance between the guide plate 4 and the guide plate 6 and the inner wall surface of the heating roller main body 1, and by tilting the fixing plate 3 and the guide plate 4 as well as the connecting plate 5 and the guide plate 6, the possibility of them affecting the heat flow is reduced, thereby facilitating the flow of heat inside the heating roller main body 1, thereby ensuring that the heat is evenly distributed inside the heating roller main body 1, making the heat conduction more uniform.

[0039] In this embodiment, only the fixing plate 3 and the guide plate 4 are set, and their positions are fixed. The heat emitted from the surface of the heating tube 2 away from the fixing plate 3 and the guide plate 4 is still not easy to dissipate, which affects the thermal conductivity of the heating roller body 1 to a certain extent.

The heat emitted from the surface of the heating tube 2 away from the connecting plate 5 and the guide plate 6 is still not easy to dissipate, which affects the thermal conductivity of the heating roller body 1 to a certain extent. In this application, by installing the third heat sink 9, the heat of the heating tube 2 adsorbed on the surface of the connecting plate 5 can be dissipated to both sides. By installing the fourth heat sink 10, the heat of the heating tube 2 adsorbed on the surface of the guide plate 6 can be dissipated to both sides, which can improve the temperature distribution of the heating roller body 1, further improve the uniformity of heat distribution inside the heating roller body 1, and improve the thermal conductivity effect; by using aluminum alloy material for the connecting plate 5 and the guide plate 6, the aluminum alloy material has a high thermal conductivity and good thermal conductivity, so it can transfer heat more effectively, thereby further improving the thermal conductivity of the heating roller body 1.
