At one end, one end of the straight rod 6 is fixedly connected to the second spur gear 12, and the second spur gear 12 is meshed with the heating ring 5 through the tooth pattern. The base 1 is provided with a slide groove, and the threaded rod 7 passes through the base 1 and is rotatably connected in the slide groove. One end of the fixed plate 4 is rotatably connected to the round rod 8, and a transmission belt is sleeved between the round rod 8 and the straight rod 6. Two sliders 13 are both threadedly connected to the outer surface of the threaded rod 7, and the sliders 13 are slidably connected in the slide groove. A load-bearing lathe 11 is fixedly connected between the two sliders 13, and a walkway is placed on the load-bearing lathe 11, and the walkway can move with the movement of the load-bearing lathe 11.

[0014] The uniform heating component also includes a first spur gear 10, one end of the round rod 8 is fixedly connected to a half-toothed gear 9, the purpose of the half-toothed gear 9 is to drive the threaded rod 7 to rotate intermittently to increase the heating time of the walkway, the first spur gear 10 is fixedly connected to one end of the threaded rod 7, the first spur gear 10 is meshed with the half-toothed gear 9, a plurality of heating blocks are fixedly connected to the outer surface of the heating ring 5, a heating air chamber 19 is fixedly connected to the outer surface of the heat transfer ring 3, the heating block transfers heat to the heating ring 5, the heating ring 5 heats the gas in the heating air chamber 19 through the heat transfer ring 3, an arcuate rack belt 14 is fixedly connected to the outer surface of the heating ring 5, the heating air chamber 14 is rotatably connected to the rotating shaft 16, one end of the rotating shaft 16 is fixedly connected to a third spur gear 15, the third spur gear 15 is meshed with the arcuate rack belt 14, the outer surface of the rotating shaft 16 is fixedly connected There is a cam 17, and an extrusion plate 18 is slidably connected in the heating air chamber 19. A straight spring is arranged between the extrusion plate 18 and the inner wall of the heating air chamber 19. The function of the straight spring is to reset the extrusion plate 18 when it is not subjected to thrust. One end of the heating air chamber 19 is fixedly connected with an air inlet pipe 20, and the other end of the heating air chamber 19 is fixedly connected with an air outlet pipe 21. An insulation chamber 22 is fixedly connected to the upper surface of the base 1, and two insulation plates 23 are fixedly connected to the bottom wall of the insulation chamber 22. A connecting pipe is arranged between the two insulation plates 23.

A one-way valve is installed in the air inlet pipe 20 to ensure that gas can only enter but not exit, and a one-way valve is installed in the air outlet pipe 21 to ensure that gas can only exit but not enter.

[0015] When the present invention is used, the straight rod 6 is driven to rotate by an external servo motor connected to the straight rod 6. The rotation of the straight rod 6 drives the second spur gear 12 to rotate. The rotation of the second spur gear 12 drives the heating ring 5 to rotate on the outer wall of the heat transfer ring 3. A plurality of heating blocks are fixedly installed on the outer surface of the heating ring 5. The heating blocks heat the heating blocks by electricity. By installing heating blocks to heat the heating ring 5, energy loss can be reduced, thereby achieving the purpose of energy saving. The rotation of the heating ring 5 drives the heating blocks to rotate, thereby completing uniform heating of the walkway. The straight rod 6 drives the round rod 8 to rotate through the transmission belt. The rotation of the round rod 8 drives the threaded rod 7 to rotate through the half-tooth gear 9 and the first spur gear 10. The rotation of the threaded rod 7 drives the two sliders 13 to move in the direction of the heating ring 5. The slider 13 drives the load-bearing lathe 11 to move, so that the walkway on the load-bearing lathe 11 can automatically enter the heating ring 5 for heat treatment.

[0016] When the heating ring 5 rotates, the arc-shaped rack belt 14 drives the third spur gear 15 to rotate, and the rotation of the third spur gear 15 drives the rotating shaft 16 to rotate. The rotation of the rotating shaft 16 intermittently pushes the extrusion plate 18 to move through the cam 17. The movement of the extrusion plate 18 allows the hot air in the heating chamber 19 to enter one of the insulation plates 23 through the air inlet pipe 20. As the hot air increases, the hot air enters another insulation plate 23 and finally returns to the heating chamber 19 through the air outlet pipe 21, saving gas loss and keeping the insulation plate 23 at a relatively high temperature at all times. The heat-treated walkway is insulated to avoid a rapid drop in temperature that causes a decrease in the mechanical properties of the walkway.
