[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides, for example Figures 1-5 The present invention relates to a heating and feeding device for a normalizing furnace, comprising a body 1, a fixed frame 2 fixedly installed on one side of the body, an active conveying roller 3 provided on the fixed frame 2, and an external drive source motor connected to one end of the active conveying roller 3, which can drive the active conveying roller 3 to rotate, thereby conveying the conveyor belt 6.

[0029] Furthermore, a support and cleaning mechanism 4 is provided on the other side of the machine body 1. A driven conveyor roller 5 is mounted on the support and cleaning mechanism 4. A conveyor belt 6 is positioned between the driving conveyor roller 3 and the driven conveyor roller 5. When the conveyor belt 6 rotates with the driving conveyor roller 3 to transport products, the driven conveyor roller 5 will rotate accordingly. The support and cleaning mechanism 4 includes: sleeves 41, telescopic brackets 42, drive rods 43, and cleaning components 44. Multiple sleeves 41 are fixedly connected to the other side of the machine body 1. The telescopic brackets 42 are slidably inserted into the inner cavity of the sleeves 41. Both ends of the driven conveyor roller 5 are rotatably inserted into multiple telescopic brackets 42 via rotating shafts. The frame 42 has an L-shaped cross-section; the drive rod 43 is located between the sleeves 41; the cleaning component 44 is located between multiple telescopic supports 42 and forms a screw drive with the drive rod 43. The rotation of the drive rod 43 can cause the cleaning component 44 to move multiple telescopic supports 42, thereby adjusting the distance between the active conveyor roller 3 and the driven conveyor roller 5, which facilitates the control of the tension of the conveyor belt 6, so that the conveyor belt 6 is always in a taut state, which is convenient for product transportation. At the same time, the cleaning component 44 can clean the impurities attached to the conveyor belt 6 after passing through the normalizing furnace, so as to ensure the normal use of the conveyor belt 6.

[0030] Furthermore, the top and bottom ends of the telescopic bracket 42 are fixedly connected to sliders 7, and the top and bottom ends of the inner wall of the sleeve 41 are provided with sliding grooves. The sliders 7 are slidably inserted into the inner cavity of the sliding grooves. The sliders 7 play a limiting role for the telescopic bracket 42, so that the telescopic bracket 42 can only slide in the horizontal direction in the inner cavity of the sleeve 41.

[0031] Specifically, the cleaning assembly 44 includes: a synchronization plate 441, a cleaning plate 442, and compression springs 443. The two sides of the synchronization plate 441 are fixedly connected to multiple telescopic brackets 42. The synchronization plate 441 is threadedly connected to the drive rod 43.

At the same time, during the sliding, it can drive multiple telescopic brackets 42 to slide within the cavity of the sleeve 41. A groove is provided at the top of the synchronization plate 441. The cleaning plate 442 is slidably inserted into the cavity of the groove. The top of the cleaning plate 442 is equipped with bristles, which can clean the conveyor belt 6. Multiple compression springs 443 are located inside the groove. One end of each of the multiple compression springs 443 is fixedly connected to the cleaning plate 442, and the other end of each of the multiple compression springs 443 is fixedly connected to the bottom end of the inner wall of the groove. The multiple compression springs 443 are always in a compressed state, which can provide an upward elastic force to the cleaning plate 442, so that the cleaning plate 442 can closely adhere to the conveyor belt 6 and clean the impurities attached to it after passing through the normalizing furnace.

[0032] Furthermore, limiting blocks 8 are fixedly connected to both sides of the cleaning plate 442, and limiting grooves are opened on both sides of the inner wall of the groove. The limiting blocks 8 are slidably inserted into the inner cavity of the limiting grooves. The limiting blocks 8 play a limiting role in the cleaning plate 442, so that the cleaning plate 442 can only slide vertically along the limiting grooves under the elastic force of the compression spring 443.

[0033] Furthermore, a support plate 9 is fixedly connected to the other side of the body 1. The support plate 9 is located between multiple sleeves 41. One end of the drive rod 43 is rotatably connected to the body 1, and the other end of the drive rod 43 is rotatably connected to the support plate 9. The cross-section of the support plate 9 is L-shaped, and the support plate 9 plays a supporting role for the drive rod 43.
