[0011] A heat dissipation screen is disposed at the bottom of the housing and blows air upward to contact the roller; and

[0012] The guide structure is arranged at the top of the shell to guide the air so as to accelerate the heat dissipation of the roller.

[0013] Specifically, the heat dissipation mesh cover is arranged directly below the roller, and fan blades for driving air flow are installed in the heat dissipation mesh cover.

[0014] Specifically, rollers are rotatably mounted in the shell through two door-shaped support bodies, and the rollers are driven to rotate through transmission wheels.

Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical contents disclosed in the present invention without affecting the effects and purposes that can be achieved by the present invention.

[0030] As described in the background art, the existing roller heating furnace only dissipates heat by opening the sealed door or combining with the bottom fan assembly, which cannot achieve rapid heat dissipation of the roller.

[0031] For the reasons stated above, please refer to the attached Figure 6 The utility model provides a roller heating furnace for rapid heat dissipation, comprising a shell 1, which has an opening on the side and a cover 2 which can be opened and closed with the shell 1 at the opening end;

[0032] A plurality of rollers 6 are evenly spaced and arranged in the housing 1 and are rotatable;

[0033] The heat dissipation screen 4 is disposed at the bottom of the housing 1 and blows air upward to contact the roller 6; and

[0034] The guide structure is arranged at the top of the shell 1 to guide the air so as to accelerate the heat dissipation of the roller 6.

[0035] Specifically, the heat dissipation mesh cover 4 is arranged directly below the roller 6 , and fan blades for driving air flow are installed in the heat dissipation mesh cover 4 .

[0036] Through the above technical features, fan blades are installed in the heat dissipation mesh cover, and the flow of air can be accelerated through the rotation of the fan blades, thereby achieving air cooling inside the shell and facilitating rapid heat dissipation of the roller.

[0037] Furthermore, the fan blades can be set to a traditional bird-wing shape, which can provide a large flow and low noise effect, and the rotating shaft of the fan blades can be driven to rotate by a micro drive motor installed in the heat dissipation mesh cover.

[0038] Specifically, rollers 6 are rotatably mounted in the housing 1 via two door-shaped supports 5 , and the rollers 6 are driven to rotate via a transmission wheel.

[0039] Through the above technical features, the door-shaped support body is provided to facilitate the rotatable installation of the roller in the shell, and to facilitate the installation of a heat dissipation mesh cover at the bottom of the roller and a guide structure at the top, thereby facilitating heat dissipation.

[0040] Furthermore, the transmission wheel can be set as a gear, and the transmission wheels of two adjacent rollers are meshed with each other to keep the two adjacent rollers rotating in opposite directions, thereby driving the aging kettle supported between the rollers to rotate and heat it evenly.

[0041] Specifically, a control box 3 is also provided on the top of the shell 1, and a plurality of control buttons and a display screen are provided on the control box 3. The control buttons are connected to a plurality of control elements in the control box 3, so as to control the rotation of the roller 6 inside the shell 1 and the internal heating, and control the rotation of the fan blades inside the heat dissipation mesh cover 4.

[0042] Through the above technical features, a control box is set on the top of the shell to facilitate operation by the staff, so that the internal heating and internal heat dissipation can be facilitated through the control button. At the same time, the heating temperature can be displayed on the display screen, thereby facilitating control.

[0043] Furthermore, the control element in the control box can be configured as a microprocessor and a driving device connected to the microprocessor, etc. The driving device includes a driving motor and a heating tube, etc. The driving motor is connected to the transmission wheel of the roller 6 to drive the internal roller to rotate, and the heating tube can heat the internal air at the same time. The microprocessor is also connected to the micro driving motor in the heat dissipation mesh cover, which is easy to control the start and stop of the micro driving motor.

[0044] Specifically, the deflector structure includes a deflector cover 7 and a deflector plate 8. The deflector cover 7 is conical and installed on the inner top of the shell 1. The deflector plate 8 is arc-shaped and installed in the deflector cover 7 with the concave surface facing downward.

[0045] Through the above technical features, the guide plate is arranged to be arc-shaped with the concave surface facing downward to facilitate the guidance of air, so that the air blown upward by the heat dissipation mesh cover can be reversely guided, so that the air flows downward, so as to cool the top of the roller and dissipate heat, thereby ensuring the uniformity of heat dissipation and improving the efficiency of heat dissipation.

[0046] Specifically, exhaust holes are provided on both sides of the top of the air guide cover 7, and the air guide plate 8 is in the shape of a mesh plate.

[0047] Through the above technical features, the exhaust holes and guide plates of the air guide cover are set as mesh plates to facilitate the discharge of internal air, thereby ensuring heat dissipation without opening the cover body, and preventing hot air from flowing out of the side opening of the shell after opening the cover body and scalding the staff.

[0048] Furthermore, a detachable baffle is provided at the bottom of the housing 1 , and the baffle can be used to block the heat dissipation mesh cover 4 .

[0049] The roller heating furnace has the same principle as the conventional roller heating furnace when heating, and it will not be described in detail here. When the heating is completed and the heat is dissipated, the cover body 2 can be opened first, and the aging kettle supported on the roller 6 can be taken out to dissipate the heat. During the heat dissipation process, the cover body 2 can be closed, and then the button switch on the control box 3 is used to control the rotation of the fan blades in the heat dissipation mesh cover 4. At this time, the baffle at the bottom of the shell is removed, and the external air can enter the shell 1 from the heat dissipation mesh cover 4 and flow upward. During the flow, it contacts the bottom of the roller 6 to realize heat exchange, and at the same time, it continues to flow upward through the gap between the rollers 6 until it contacts the guide plate 8. A part of the air passes through the mesh and enters the guide cover 7 and is discharged from the side, and the other part flows downward in the opposite direction under the action of the guide plate 8 until it contacts the top of the roller 6, thereby realizing uniform heat dissipation of the roller 6 and accelerating the heat dissipation time.

[0050] The above description is a detailed description of the preferred feasible embodiment of the utility model, but the embodiment is not used to limit the scope of the patent application of the utility model. All equivalent changes or modified changes completed under the technical spirit suggested by the utility model should fall within the patent scope covered by the utility model.
