[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] Please see Figure 1-4 This utility model discloses a feeding device for heat treatment, including a heat treatment furnace 1, a placement groove 2 inside the heat treatment furnace 1, a frame 3 inside the placement groove 2, a plurality of base frames 4 and a cavity 5 at the bottom of the frame 3, a rack 8 at the bottom end of the frame 3, a first motor 6 on one side of the heat treatment furnace 1, a rotating shaft 7 at the output end of the first motor 6, and a toothed block 11 on the rotating shaft 7 that meshes with the rack 8.

[0029] Two side blocks 12 are symmetrically arranged at the outer end of the frame 3, and a crossbar 13 is provided in front of the heat treatment furnace 1 through the side blocks 12.

[0030] In this embodiment, both the first motor 6 and the second motor 18 are servo motors.

[0031] In this embodiment, the two ends of the top plate 17 are fixed to the top of the support rod 15 by screws.

[0032] Overall Structure and Initial State: This heat treatment feeding device mainly consists of a heat treatment furnace 1, a placement tank 2, a frame 3, a base frame 4, a cavity 5, a rack 8, a first motor 6, a rotating shaft 7, a toothed block 11, a side block 12, a horizontal bar 13, a bottom plate 14, a vertical bar 10, a bent bar 16, a support rod 15, a top plate 17, a second motor 18, and a screw 9. In the initial state, the frame 3 is located in the placement tank 2 inside the heat treatment furnace 1, and all components are in a static state.

[0033] Frame 3 Extraction and Loading Process: When loading is required, the first motor 6 (servo motor) is activated. The output of the first motor 6 drives the rotating shaft 7 to rotate. Since the toothed block 11 on the rotating shaft 7 meshes with the rack 8 at the bottom of the frame 3, the rotation of the toothed block 11 will drive the frame 3 to be extracted out of the placement slot 2 through the rack 8. After the frame 3 is extracted, the operator can place the steel plate that needs to be heat-treated into the frame 3. After placement, the first motor 6 is activated again to reverse its direction. Through the cooperation of the toothed block 11 and the rack 8, the frame 3 carries the steel plate back into the placement slot 2, completing the loading process. This process achieves automated loading, avoiding manual placement of steel plates into the placement slot 2 and reducing the risk of burns to the operator.

[0034] In this embodiment, a base plate 14 is provided in front of the heat treatment furnace 1, located below the frame 3. The upper end of the base plate 14 is provided with a plurality of vertical rods 10 penetrating the cavity 5. The two sides of the base plate 14 are provided with bent rods 16 located on both sides of the heat treatment furnace 1. The rear end of the bent rods 16 is provided with a support rod 15. The top of the heat treatment furnace 1 is provided with a top plate 17 connecting the support rods 15. A second motor 18 is provided above the heat treatment furnace 1. The output end of the second motor 18 is provided with a screw 9 penetrating the top plate 17.

[0035] In this embodiment, the support rod 15, the bent rod 16, and the base plate 14 are an integral structure.

[0036] In this embodiment, the top of the vertical rod 10 is provided with anti-slip texture.

[0037] Post-heat treatment unloading process: After the steel plate has undergone heat treatment, it needs to be removed from the frame 3. At this time, the first motor 6 is started to pull the frame 3 out of the placement slot 2 again. After the frame 3 is pulled out, the second motor 18 (servo motor) is started. The output of the second motor 18 drives the screw 9 to rotate. Since the screw 9 passes through the top plate 17, and the top plate 17 is connected to the support rod 15, the support rod 15, the bent rod 16, and the bottom plate 14 are an integrated structure. The rotation of the screw 9 causes the top plate 17 to lift the support rod 15, which in turn pulls the bent rod 16 upwards, thus causing the bottom plate 14 to lift along with multiple vertical rods 10. The vertical rods 10 pass through the cavity 5 at the bottom of the frame 3, pushing the heat-treated steel plate upwards within the frame 3, making it easy for operators to remove the steel plate and achieving automated unloading.

[0038] The auxiliary structure serves several purposes: Two symmetrically arranged side blocks 12 at the outer ends of frame 3 cooperate with the crossbar 13 penetrating the front of the heat treatment furnace 1, guiding and stabilizing the movement of frame 3. This ensures smooth movement of frame 3 during extraction and repositioning, preventing swaying or deviation. The anti-slip textured top of the vertical rod 10 increases friction between the vertical rod 10 and the steel plate, better preventing slippage during steel plate ejection and improving the stability and safety of the discharge process. The top plate 17 is fixed to the top of the support rod 15 at both ends with screws, ensuring a secure connection between the top plate 17 and the support rod 15, and enabling stable operation of the entire lifting structure.

[0039] Both the first motor 6 and the second motor 18 are servo motors. Servo motors are characterized by high precision, high response speed and high stability. They can accurately control the movement of the frame 3 and the lifting height of the vertical rod 10, ensuring the accuracy of the feeding process and improving the processing quality of heat treatment.
