The execution module controls the lifting and conveying mechanism to drive the conveyor belt 115 to ascend according to the ascending height execution value.

If the descending adjustment threshold SYZ is less than zero, the height adjustment value T2 and the distance Q3*n1 between the lower end of the conveyor belt 115 and the lower surface of the tempering furnace body 20 are extracted as the ascending height execution value and sent to the execution module, and the execution module controls the lifting and conveying mechanism to drive the conveyor belt 115 to ascend according to the ascending height execution value;

If the height adjustment value T2 is greater than zero, the descending height adjustment value T2 and the height Q2 of the conveyor belt 115 from the surface of the support seat 10 are substituted into the preset formula: XYZ=Q2×a1-T2×a2 to obtain the ascending adjustment threshold XYZ, where a1 and a2 are preset adjustment threshold factors. If the adjustment threshold YZ is greater than zero, the value of the height adjustment value T2 is extracted as the descending height execution value and sent to the execution module. The execution module controls the lifting and conveying mechanism to drive the conveyor belt 115 to descend according to the descending height execution value.

If the height adjustment value T2 is less than zero, the height adjustment value T2 and the distance Q3 between the conveyor belt 115 between the second transmission roller 19 and the third transmission roller 111 and the lower surface of the tempering furnace body 20 are substituted into the preset formula: SYZ = Q3 × n1-T2 × n2 to obtain the descending adjustment threshold SYZ, wherein n1 and n2 are preset belt working gap factors. If the descending adjustment threshold SYZ is greater than zero, it means that the ascending adjustment distance is within the adjustable range. At this time, the height adjustment value T2 is extracted as the ascending height execution value and sent to the execution module. The execution module controls the lifting and conveying mechanism to drive the conveyor belt 115 to ascend according to the ascending height execution value.

If the descending adjustment threshold SYZ is less than zero, the height adjustment value T2 and the distance Q3*n1 between the lower end of the conveyor belt 115 and the lower surface of the tempering furnace body 20 are extracted as the ascending height execution value and sent to the execution module, and the execution module controls the lifting and conveying mechanism to drive the conveyor belt 115 to ascend according to the ascending height execution value;

If the height adjustment value T2 is greater than zero, the descending height adjustment value T2 and the height Q2 of the conveyor belt 115 from the surface of the support seat 10 are substituted into the preset formula: XYZ=Q2×a1-T2×a2 to obtain the ascending adjustment threshold XYZ, where a1 and a2 are preset adjustment threshold factors. If the adjustment threshold YZ is greater than zero, the value of the height adjustment value T2 is extracted as the descending height execution value and sent to the execution module. The execution module controls the lifting and conveying mechanism to drive the conveyor belt 115 to descend according to the descending height execution value.

If the adjustment threshold YZ is less than zero, it means that the workpiece cannot be processed by the device, and a processing failure signal is generated and sent to the execution module;

The process of the execution module controlling the lifting and conveying mechanism to drive the conveyor belt 115 to lift is as follows: by controlling the first servo motor 12 to work, the first threaded rod 13 is rotated. When the first threaded rod 13 rotates, the lifting slider 14 can be moved up and down inside the lifting rail 11 under the limiting action of the lifting rail 11. When the lifting slider 14 moves up and down, the first transmission roller 18 and the second transmission roller 19 can be driven to move up and down through the action of the connecting frame 15 and the supporting frame 16. At the same time, since one end of the third transmission roller 111 and the fourth transmission roller 112 is also provided with a lifting and conveying mechanism, that is, by making the first servo motors 12 in the two sets of lifting and conveying mechanisms work at the same time, the first transmission roller 18, the second transmission roller 19, the third transmission roller 111 and the fourth transmission roller 112 can be driven to move up and down within the range of the lifting rail 11, thereby driving the conveyor belt 115 to move up and down. The execution module can control the first servo motor 12 to work according to the rising height execution value or the falling height execution value. When the conveyor belt 115 reaches the corresponding height, the first servo motor 12 stops working;

When a workpiece with a larger specification needs to be processed, it can be fixed by a clamping conveying mechanism, that is, first, the workpiece to be processed on the conveyor belt 115 is placed in the middle of the two sets of limit clamping blocks 211, and the third threaded rod 210 is driven to rotate by rotating the two sets of rotating handles 212. When the third threaded rod 210 rotates, the limit clamping block 211 can move in the limit slide rail 29 and move toward the workpiece to be processed under the limited rotation of the limit slide rail 29. By making the two sets of limit clamping blocks 211 approach the workpiece to be processed at the same time, the two sets of limit clamping blocks 211 can squeeze the workpiece to be processed against each other, thereby achieving the purpose of fixing. After the workpiece to be processed is fixed, the second servo motor 17 is started to rotate the first transmission roller 18, the first transmission belt 110, the second transmission roller 1 9. The conveyor belt 115 can be driven to rotate and convey the workpiece to the tempering furnace body 20 for processing under the auxiliary action of the second transmission belt 113, the third transmission roller 111, and the fourth transmission roller 112. At the same time, the third servo motor 23 is started. The third servo motor 23 works and can simultaneously rotate the two groups of first rotating shafts 24 under the action of the fourth transmission belt 25 and the sixth transmission belt 27. When the first rotating shaft 24 rotates, the two groups of second threaded rods 22 can be driven to rotate through the action of the fifth transmission belt 26. When the second threaded rod 22 rotates, the movable slider 28 can be moved in the movable slide rail 21. By controlling the power output and rotation direction of the third servo motor 23, the movable slider 28 can be moved synchronously with the conveyor belt 115, thereby playing a role in conveying and clamping the large workpiece on the conveyor belt 115.

When the workpiece is transported to the horizontal tempering furnace for processing, sealing components are installed on both side walls of the tempering furnace body 20, and the sealing components can be used to seal the openings at both ends of the tempering furnace body 20. That is, the position of the conveyor belt 115 at this time is first determined, and according to the position of the conveyor belt 115, the fourth threaded rod 32c is driven to rotate by the micro motor 32b, and then the sealing lifting plate 32d is driven to shrink or stretch on the sealing receiving plate 32a to adjust the width of the sealing plate 32, so that the width of the sealing plate 32 is just the height of the distance between the conveyor belt 115 and the movable slide rail 21. The electric slider 33 is then driven to slide toward the interior of the tempering furnace body 20 in the sealing box 31, thereby driving the sealing plate 32 to slide toward the interior of the tempering furnace body 20, and the sealing plates 32 on both sides of the tempering furnace body 20 are matched, thereby achieving a certain sealing of the openings at both ends of the tempering furnace body 20. When the workpiece to be processed is completed, the sealing plate 32 in the sealing assembly will shrink back into the sealing box 31, so that the output port of the tempering furnace body 20 is opened, so that the workpiece is transported out of the tempering furnace body 20 under the action of the conveyor belt 115.
