[0025] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0026] like Figures 1 to 7 As shown, a high-temperature resistant mesh belt heating furnace provided by an embodiment of the present invention includes a base 1, a driving motor 2 is fixedly installed on the front of the base 1, and the output shaft of the driving motor 2 is fixedly sleeved with a rotating shaft 3, and the outer surface of the rotating shaft 3 is fixedly sleeved with a driving wheel 4, and the inner wall of the base 1 is rotatably connected to the side of the driving wheel 4. A mesh belt 6 is transmission-connected between the driven wheel 5 and the driving wheel 4, and a frame 7 is fixedly installed on the base 1. Heating plates 8 are provided on both sides of the frame 7, and the heating plates 8 and the frame 7 are connected by a clamping structure. A heating wire 9 is fixedly installed on the inner surface of the heating plate 8, a through hole 10 is provided on the heating plate 8, and a clamping groove 11 communicating with the through hole 10 is provided on the frame 7. Handles 12 are fixedly installed on both ends of the outer side of the heating plate 8, and the clamping structure includes a guide rod 13, which is fixedly installed on the inner wall of the through hole 10, and a clamping block 14 is movably sleeved on both sides of the guide rod 13, and the clamping block 14 is movably clamped in the inside of the clamping groove 11.

[0027] By moving the two clamping blocks 14 toward each other, the mutual clamping state between the clamping blocks 14 and the frame 7 can be released, thereby releasing the limiting effect on the heating plate 8. The staff can then remove the heating plate 8 from the frame 7, making it easier to maintain or replace the heating wire 9.

[0028] Furthermore, a push-pull rod 15 is movably connected between the two clamping blocks 14 . An oblique hole 16 is formed on the clamping block 14 . A round block 17 located inside the oblique hole 16 is fixedly connected to the push-pull rod 15 .

[0029] When holding the handle 12, the staff can pull the push-pull rod 15 with their fingers, so that the push-pull rod 15 drives the round block 17 to slide inside the inclined hole 16, and then the outer surface of the round block 17 can squeeze the inner wall of the inclined hole 16, so that the two blocking blocks 14 can move toward each other to release the limiting effect on the heating plate 8.

[0030] Furthermore, a first spring 18 is movably sleeved on the outer surface of the guide rod 13 , and two ends of the first spring 18 are fixedly connected to the two clamping blocks 14 respectively.

[0031] By setting the first spring 18 to a compressed state, the two clamping blocks 14 will tend to move away from each other due to the elastic force of the first spring 18 , so that the clamping blocks 14 can maintain the limiting effect on the heating plate 8 .

[0032] Furthermore, a cleaning roller 19 is provided at the bottom of the base 1, and the cleaning roller 19 is connected to the base 1 through a sliding structure. The sliding structure includes a vertical rod 20. There are two vertical rods 20, and the two vertical rods 20 are fixedly installed on both sides of the base 1. A slider 21 is movably sleeved on the outer surface of the vertical rod 20, and a square frame 22 is fixedly installed on one end of the slider 21 close to the cleaning roller 19, and the cleaning roller 19 is movably inserted into the square frame 22.

[0033] By moving the slider 21 upward, the cleaning roller 19 can be driven to move upward, so that the cleaning roller 19 can contact the bottom of the mesh belt 6, and then the cleaning roller 19 can clean the mesh belt 6.

[0034] Furthermore, the cleaning roller 19 is provided with a circular groove 23 located inside the square frame 22 , and a latch 24 is movably inserted into the square frame 22 . One end of the latch 24 is movably inserted into the circular groove 23 , and the other end of the latch 24 is fixedly connected to a handle 25 .

[0035] By pulling the handle 25 , the latch 24 can be withdrawn from the circular groove 23 , thereby releasing the limiting effect on the cleaning roller 19 , making it easier for staff to disassemble the cleaning roller 19 and clean or replace it.

[0036] Furthermore, a second spring 26 located between the frame 22 and the handle 25 is movably sleeved on the outer surface of the latch 24 , and two ends of the second spring 26 are fixedly connected to the surface of the frame 22 and the handle 25 , respectively.

[0037] By setting the second spring 26 to a stretched state, the handle 25 tends to move closer to the frame 22 due to the elastic force of the second spring 26 , so that the latch 24 can be retained inside the circular groove 23 , thereby maintaining the limiting effect on the cleaning roller 19 .

[0038] Furthermore, a brake motor 27 is fixedly installed on the front of the base 1, and the output shaft of the brake motor 27 is fixedly sleeved with a bidirectional screw rod 28. Both ends of the outer surface of the bidirectional screw rod 28 are threadedly sleeved with movable blocks 29, and a connecting rod 30 is hinged between the movable block 29 and the slider 21.

[0039] By starting the brake motor 27 to rotate the bidirectional screw 28, the two movable blocks 29 can move toward or away from each other. When the two movable blocks 29 move away from each other, the slider 21 will be pulled upward through the connecting rod 30, so that the cleaning roller 19 can move upward and close to the mesh belt 6, thereby realizing the cleaning operation of the mesh belt 6.

[0040] When using the equipment to heat the workpiece, the staff can start the heating wire 9 and the driving motor 2. Due to the operation of the driving motor 2, the rotating shaft 3 will drive the active wheel 4 to rotate, so that the driven wheel 5 can drive the mesh belt 6 to rotate together, and then the workpiece is placed on one side of the top of the mesh belt 6. As the mesh belt 6 rotates, the workpiece is driven through the inside of the frame 7, and the heating wire 9 heats the workpiece; when the mesh belt 6 needs to be cleaned, the staff can start the brake motor 27. Due to the operation of the brake motor 27, the bidirectional screw rod 28 will rotate, so that the two movable blocks 29 can move toward or away from each other. When the two movable blocks 29 move away from each other, the slider 21 can be driven to move upward along the surface of the vertical rod 20 through the connecting rod 30, so that the box 22 can drive the cleaning roller 19 to move upward to contact the bottom of the mesh belt 6, and then the mesh belt 6 can be cleaned, thereby removing oil and other substances remaining on the mesh belt 6, thereby improving the subsequent processing quality of the workpiece.

[0041] When the cleaning roller 19 has been used for a long time and needs to be removed for cleaning or replacement, the staff can pull the handle 25, so that the pin 24 moves away from the circular groove 23 and stretches the second spring 26. When the part of the pin 24 located inside the circular groove 23 is pulled out, the limiting effect on the cleaning roller 19 is released, and the staff can remove the cleaning roller 19, thereby facilitating the disassembly of the cleaning roller 19 and making it convenient for the staff to clean the cleaning roller 19.

[0042] When the staff needs to disassemble the heating plate 8 to perform maintenance and inspection on the inside of the frame 7 or the heating wire 9, they can hold the handle 12 and pull the push-pull rod 15 with their fingers, so that the outer surface of the round block 17 squeezes the inner wall of the inclined hole 16, thereby enabling the two blocks 14 to move toward each other and compress the first spring 18, thereby releasing the limiting effect of the block 14 on the heating plate 8, and then the heating plate 8 can be removed from the frame 7 without using special tools to remove multiple screws, thereby facilitating the staff's maintenance work and improving work efficiency.

[0043] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
