[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention. Embodiment 1

[0028] Please refer to Figure 1-6As shown in the figure, a mesh belt type normalizing furnace for processing automotive parts includes a normalizing furnace 1, a conveyor belt 11, and a loading box 12. The conveyor belt 11 is installed inside the normalizing furnace 1. Multiple groups of loading boxes 12 are fixedly connected to the top surface of the conveyor belt 11. First chutes 13 are respectively opened on the side walls at both ends of the loading box 12. A connecting rod 14 is slidably connected to the middle of the loading box 12. Both side walls of the connecting rod 14 are slidably connected inside the first chutes 13. A pair of limiting blocks 15 are respectively slidably connected to both side walls of the connecting rod 14. A spring is used to connect between the pair of limiting blocks 15. The end of the limiting block 15 is in contact with the side wall of the first chute 13. During operation, when an object needs to be heated by the normalizing furnace, the staff can place the object to be heated on the connecting rod 14 between the loading boxes 12, and use the loading box 12 to protect the surroundings of the object to be heated. At the same time, the staff can, according to the size of the object to be heated, control the height of the connecting rod 14 inside the first chute 13 by squeezing the limiting block 15, so as to adjust the position of the connecting rod 14. This step uses the blocking effect of the loading box 12 on the object to be heated, and can protect the object to be heated during the movement of the conveyor belt 11, reducing the situation that the object to be heated falls off the conveyor belt 11 due to vibration. At the same time, the movable connecting rod 14 inside the loading box 12 can adjust the height according to the size of the object to be heated, increasing the adaptability of the equipment to different objects to be heated.

[0029] Multiple groups of first support rods 2 are fixedly connected to the top of the conveyor belt 11 at the gaps of the connecting rods 14. Second chutes 21 are respectively opened on the side walls around the first support rods 2. A first slider 23 is slidably connected inside the second chutes 21. A spring is used to connect between the second chutes 21 and the first slider 23. One end of a second support rod 22 is respectively hinged to the top of the second chute 21 and the middle of the first slider 23. The closer ends of the pair of second support rods 22 are connected by a first rotating shaft 24. During operation, when facing a cylindrical object to be heated, multiple groups of first support rods 2 installed on the top surface of the conveyor belt 11 can be exposed after the connecting rod 14 moves downward and inserted into the cylindrical object to be heated. At this time, the first slider 23 will move upward under the action of the spring, driving the second support rod 22 to bend along the first rotating shaft 24, so that the end of the first rotating shaft 24 is in contact with the side wall of the cylindrical object to be heated. This step uses the installation of multiple groups of first support rods 2. When a cylindrical object to be heated appears, the contact and extrusion of the side wall of the cylindrical object to be heated by the first rotating shaft 24 are used to complete the limitation of the object to be heated, further improving the fixing effect on different objects to be heated and reducing the occurrence of the rolling phenomenon of the object to be heated.

[0030] A support pad 3 is fixedly connected to the side wall of the first rotating shaft 24; a third sliding groove 31 is formed in the side wall of the support pad 3; the third sliding grooves 31 are multiple groups and are continuously formed in a wavy shape; during operation, when the first rotating shaft 24 contacts the side wall of the object to be heated, the support pad 3 installed on the side wall of the first rotating shaft 24 can provide additional friction for it. At the same time, the multiple groups of third sliding grooves 31 formed in the side wall of the support pad 3 can increase additional support points according to the side wall structure of the object to be heated. This step utilizes the support pad 3 installed on the side wall of the first rotating shaft 24 to increase the contact area between the two when contacting the object to be heated, thereby improving the support effect, further enhancing the fixing effect on the object to be heated, and reducing the occurrence of sliding.

[0031] Elastic bands 4 are fixedly connected to the upper and lower side walls of the support pad 3; the other ends of the elastic bands 4 are fixedly connected to the side wall of the second support rod 22; during operation, when the cylindrical object to be heated contacts the first support rod 2, since the second support rod 22 will be extruded outward under the action of the spring, the side wall of the second support rod 22 will contact the side wall of the object to be heated. At this time, the elastic bands 4 made of high-temperature resistant materials installed on the upper and lower side walls of the support pad 3 can play a guiding role, enabling the object to be heated to move smoothly on the second support rod 22. This step utilizes the elastic bands 4 installed on the side wall of the second support rod 22 to smoothly guide the object to be heated to contact the support pad 3 and provide a support effect when the cylindrical object to be heated moves, by using the angle between the elastic bands 4 and the support pad 3.

[0032] A fourth sliding groove 5 is formed in the side wall of the second support rod 22; a connecting block 51 is slidably connected inside the fourth sliding groove 5; the other end of the connecting block 51 is fixedly connected to the side wall of the elastic band 4; the fourth sliding groove 5 and the connecting block 51 are connected by a spring; multiple fifth sliding grooves 52 are formed in the side wall of the fourth sliding groove 5; an impact plate 53 is slidably connected inside the fifth sliding groove 52; during operation, during the bending process of the second support rod 22, the distance between the elastic band 4 and the second support rod 22 will be pulled apart and approached. At this time, the movement of the elastic band 4 in cooperation with the spring force will drive the connecting block 51 to move inside the fourth sliding groove 5. As the connecting block 51 moves, the impact plate 53 will contact the side wall of the connecting block 51. During the continuous movement, multiple impact plates 53 will contact and collide with the connecting block 51. This step utilizes the movement effect of the elastic band 4 to drive the overall movement of the connecting block 51, and drives the impact plate 53 to collide with the side wall of the connecting block 51 through the movement effect, generating a vibration effect to shake off the dust existing on the support pad 3 and reduce the adhesion of dust impurities.

[0033] Both side walls of the loading box 12 are provided with sixth chutes 6; a pair of second sliders 61 are slidably connected to the inside of the pair of sixth chutes 6; a connecting plate 62 is fixedly connected between the pair of corresponding second sliders 61; during operation, when the staff faces a large object to be heated, by utilizing the mobility of the second slider 61, the side wall of the second slider 61 can be used to clamp the side wall of the object to be heated by moving the second slider 61, and the loading box 12 is used to increase the stability effect of the object to be heated. In this step, by utilizing the mobility of the second slider 61, a pair of connecting plates 62 can be driven to clamp the side wall of the object to be heated, increasing the stability of the object to be heated. At the same time, the occurrence of the object to be heated sliding is reduced.

[0034] A plurality of connecting columns 7 are fixedly connected to the top surface of the connecting rod 14; a plurality of seventh chutes 71 are opened on the top surface of the connecting column 7; during operation, when the top of the connecting rod 14 comes into contact with the object to be heated, the connecting columns 7 opened on the top surface of the connecting rod 14 can come into contact with the object to be heated first. At this time, the connecting columns 7 can lift the object to be heated, reducing the contact surface, and at the same time, using the depression of the seventh chutes 71 to clamp the corners of the object to be heated. In this step, by using the connecting columns 7, the object to be heated can be lifted partially, reducing the contact area with the object to be heated. At the same time, the opening of the seventh chutes 71 can provide an additional support at the protruding corners of the object to be heated, providing support for the object to be heated.

[0035] A plurality of eighth chutes 8 are opened at the top ends of the plurality of connecting columns 7; during operation, when the connecting columns 7 come into contact with the object to be heated, the eighth chutes 8 opened at the top ends of the connecting columns 7 can, according to the shape of the object to be heated, assist the object to be heated with corners to clamp the corners inside the eighth chutes 8. In this step, by using the eighth chutes 8 opened on the top surface of the connecting columns 7, the object to be heated can be secondarily fixed when the corners of the object to be heated are inserted into the eighth chutes 8, thereby increasing the stability of the object to be heated. Embodiment 2

[0036] Please refer to Figure 7 As shown, compared with Embodiment 1, as another implementation manner of the present invention, an anti-slip pad 9 is fixedly connected to the bottom of the normalizing furnace 1; during operation, during the operation of the normalizing furnace 1, the anti-slip pad 9 installed on the bottom of the normalizing furnace 1 can increase the friction between the normalizing furnace 1 and the ground, assisting the normalizing furnace 1 to run smoothly on the ground. In this step, by using the additional friction effect provided by the anti-slip pad 9, the situation of the normalizing furnace 1 sliding during operation can be reduced, maintaining the stability of the normalizing furnace 1 during operation.

[0037] Working principle: During operation, when an object needs to be heated in a normalizing furnace, the operator can place the object to be heated on the connecting rod 14 between the loading boxes 12. The loading boxes 12 protect the periphery of the object to be heated. At the same time, the operator can adjust the height of the connecting rod 14 inside the first chute 13 by squeezing the limit block 15 according to the size of the object to be heated, thereby adjusting the position of the connecting rod 14. When facing a cylindrical object to be heated, multiple groups of first support rods 2 installed on the top surface of the conveyor belt 11 can be exposed after the connecting rod 14 moves downward and inserted into the cylindrical object to be heated. At this time, the first slider 23 will move upward under the action of the spring, driving the second support rod 22 to bend along the first rotating shaft 24, so that the end of the first rotating shaft 24 contacts the side wall of the cylindrical object to be heated. When the first rotating shaft 24 contacts the side wall of the object to be heated, the support pad 3 installed on the side wall of the first rotating shaft 24 can provide additional friction for it. At the same time, multiple groups of third chutes 31 opened on the side wall of the support pad 3 can provide additional support points according to the side wall structure of the object to be heated. When the cylindrical object to be heated contacts the first support rod 2, the second support rod 22 will be extruded outward under the action of the spring, causing the side wall of the second support rod 22 to contact the side wall of the object to be heated. At this time, the elastic bands 4 made of high-temperature resistant materials installed on the upper and lower side walls of the support pad 3 can play a guiding role, enabling the object to be heated to move smoothly on the second support rod 22. During the bending process of the second support rod 22, the distance between the elastic band 4 and the second support rod 22 will increase and decrease. At this time, the movement of the elastic band 4 and the elastic force of the spring will drive the connecting block 51 to move inside the fourth chute 5. As the connecting block 51 moves, the impact plate 53 will contact the side wall of the connecting block 51. During continuous movement, multiple groups of impact plates 53 will all contact and collide with the connecting block 51. When the operator faces a large object to be heated, using the movability of the second slider 61, the side wall of the second slider 61 can be used to clamp the side wall of the object to be heated by moving the second slider 61, cooperating with the loading box 12 to increase the stability of the object to be heated. When the top of the connecting rod 14 contacts the object to be heated, the connecting column 7 opened on the top surface of the connecting rod 14 can first contact the object to be heated. At this time, the connecting column 7 can lift the object to be heated, reducing the contact surface and using the depression of the seventh chute 71 to clamp the corners of the object to be heated. When the connecting column 7 contacts the object to be heated, the eighth chute 8 opened at the top end of the connecting column 7 can assist the object to be heated with corners to clamp the corners inside the eighth chute 8 according to the shape of the object to be heated.
