[0015] The present invention will be further described below with reference to the embodiments.

[0016] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0017] Please see Figure 1 and Figure 3 This utility model provides a multi-station bar heating and feeding device, including a frame 1, an inner frame 8 installed inside the frame 1, the frame 1 has an I-shaped structure, the inner frame 8 is fixed inside the frame 1, and the height of the hopper 2 is higher than the height of the fixed toothed plate 4.

[0018] In this embodiment, several support legs are provided on the top of the frame 1 for the stable installation of the fixed toothed plates 4 on both sides. The inner frame 8 is fixed to the inside of the frame 1 by bolts, allowing the bar stock 7 inside the hopper 2 to flow downward to the top of the fixed toothed plates 4.

[0019] Please see Figure 1 and Figure 2 A hopper 2 is installed on one side of the frame 1. The hopper 2 contains multiple bars 7. Several support legs 21 are fixedly installed at the bottom of the hopper 2, and the bottom of the hopper 2 is provided with a sloping bottom 22. A feeding plate 23 is provided above one side of the hopper 2, and a discharge channel 24 is provided below the other side of the hopper 2.

[0020] In this embodiment, the operator places the bar stock 7 inside the hopper 2, and the bar stock 7 flows down the inclined bottom 22 from the discharge channel 24, thereby placing the bar stock 7 above the fixed toothed plate 4.

[0021] Please see Figure 1 and Figure 3A lifting mechanism 3 is provided above the bottom of the inner frame 8. The lifting mechanism 3 is used to lift the toothed plate 5 up and down. The lifting mechanism 3 includes a cylinder 31 fixed inside the lower part of the inner frame 8. A telescopic rod 32 is provided inside one end of the cylinder 31. A wedge block 33 is fixedly installed at the end of the telescopic rod 32. A guide rail 34 located below the wedge block 33 is fixed above the inner frame 8, and the wedge block 33 slides horizontally and linearly along the guide rail 34.

[0022] In this embodiment, the lifting mechanism 3 can drive the wedge block 33 to move linearly, while the wedge block 33 slides on the guide rail 34, ensuring the stability of the movement of the wedge block 33. The upper surface of the wedge block 33 is a slope structure, which can drive the lifting arm 54 to move up and down, so as to realize the lifting toothed plate 5.

[0023] Please see Figure 1 , Figure 5 and Figure 6 Fixed toothed plates 4 are fixedly installed on both sides of the top of the frame 1, and lifting toothed plates 5 are provided on both sides of the top of the inner frame 8. The lifting toothed plates 5 are located inside the fixed toothed plates 4. The cooperation between the fixed toothed plates 4 and the lifting toothed plates 5 realizes the forward conveying of the bar stock 7. The fixed toothed plates 4 and the lifting toothed plates 5 are laterally staggered. A bracket 51 is fixedly installed at the bottom of the lifting toothed plates 5, and several guide rods 52 are fixedly installed at the bottom of the bracket 51. Several sleeves 53 are fixedly installed on the top of the inner frame 8 and fitted outside the guide rods 52. A lifting arm 54 is fixedly installed below the bracket 51.

[0024] In this embodiment, the reciprocating lifting motion of the lifting toothed plate 5 inside the fixed toothed plate 4 is used to realize the forward conveying of the bar stock 7 above the fixed toothed plate 4. While the lifting toothed plate 5 is moving up and down, the guide rod 52 slides inside the sleeve 53, which plays a good guiding role.

[0025] Please see Figure 1 and Figure 4 Heating modules 6 are provided on both sides of the lifting toothed plate 5. The heating module 6 includes a connecting seat 61 connected to the outside of the lifting toothed plate 5, and a shifting plate 62 is fixedly installed on the top of the connecting seat 61. The shifting plate 62 extends outward, bypasses the fixed toothed plate 4 and moves up and down synchronously with the lifting toothed plate 5, so that the end of the bar stock 7 can always be located inside the induction heater 64. Sealing plates 63 are fixedly installed on both sides of the shifting plate 62. The induction heater 64 is provided inside the top of the shifting plate 62. The induction heater 64 is a high-frequency magnetic induction heater, which is a commonly used structure in the prior art. A control panel 65 is provided on the outside of the shifting plate 62. The temperature of the induction heater 64 can be adjusted through the control panel 65.

[0026] In this embodiment, it should be noted that there are multiple heating modules 6. As the bar stock 7 moves forward, the heating temperature of the heating modules 6 located on the same side can be increased step by step. The heating modules 6 located on both sides of the lifting toothed plate 5 have the same temperature, thereby achieving the purpose of multi-stage heating of the bar stock 7 and improving the heating effect of the bar stock 7.

[0027] The working principle and usage process of this utility model are as follows: First, the operator places multiple bars 7 inside the hopper 2. Since the bottom of the hopper 2 is a sloping bottom 22, the bars 7 inside it can automatically enter the top of the fixed toothed plate 4. Next, the lifting mechanism 3 is started, and the cylinder 31 drives the telescopic rod 32 to move back and forth, thereby causing the wedge block 33 to drive the lifting arm 54 to move up and down. The bracket 51 can drive the lifting toothed plate 5 to move back and forth inside the fixed toothed plate 4. The lifting toothed plate 5 lifts the bar 7 located above the fixed toothed plate 4. As the lifting toothed plate 5 descends, the bar 7 enters the fixed toothed plate 4 located at the front. This process is repeated to achieve the purpose of uniformly conveying the bar 7 forward. When the bar stock 7 is being conveyed forward, the heating module 6 located on the side of the lifting toothed plate 5 is activated, which can achieve the heating effect on the end of the bar stock 7 (depending on the design of the shape of the heating module 6, it is not limited to heating the end of the bar stock 7, but can also achieve the heating effect on the entire surface of the bar stock 7).

[0028] In the above scheme, it should be noted that: the cylinder 31, the induction heater 64 and the control panel 65 in this application are all existing products, and the specific structure and working principle of the cylinder 31, the induction heater 64 and the control panel 65 are all existing publicly disclosed technical means. At the same time, the pipeline layout of the cylinder 31 adopts existing conventional technical means, and the electrical connection method (circuit layout) and control method between the induction heater 64 and the control panel 65 also adopt existing conventional technical means, which will not be described in detail here.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
