Generally, the feeding and discharging of the sintering furnace need to be manually operated, which not only consumes a lot of manpower and time and increases labor intensity, but also requires the operator to contact high-temperature materials, which increases the risk of scalding. Therefore, a feeding and discharging device for a sintering furnace is needed to facilitate the feeding and discharging of graphite boxes. SUMMARY

[0004] In order to overcome the above-mentioned deficiencies, the utility model aims to provide a feeding and discharging device for a sintering furnace, which places the graphite box containing powder on the first conveying roller for horizontal movement and transportation. After moving to the second conveying roller on one side, the piston rod is extended by the cylinder to expand the scissor frame, so as to realize the lifting action, so that the graphite box on the second conveying roller is lifted to the specified position, and then it is moved into the sintering furnace by pushing. The discharging is the opposite. The automatic feeding and discharging replaces the complicated manual operation, reduces the demand for manpower, reduces labor intensity and labor cost, makes the production process more smooth and efficient, reduces the safety hazards caused by human operation, and improves the safety of the production process.

[0005] The technical solution of the utility model to solve the technical problem is:

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] like Figures 1 to 4 As shown, the present invention provides a sintering furnace feeding and unloading device, comprising a first frame 1, a second frame 4, a lifting frame 5, and a second conveying roller 7.

[0022] In this utility model, a first conveying roller 2 is provided on the top of the first frame 1, a second frame 4 is provided on one side of the first frame 1, and universal wheels 9 are evenly distributed at the bottom of the first frame 1 and the second frame 4, so that the first frame 1 and the second frame 4 can be moved to one side of the sintering furnace by means of the universal wheels 9.

[0023] In this invention, first rollers 3 are evenly distributed inside the first conveying roller 2. A graphite box containing powder is placed on the first conveying roller 2, and an external force drives the graphite box. At the same time, as the first rollers 3 rotate, the graphite box is moved horizontally.

[0024] In this utility model, a lifting frame 5 is connected to the top of the second frame 4. The lifting frame 5 is connected to the second conveyor roller 7 through a scissor frame 8. A cylinder 6 is provided at the center of the top of the lifting frame 5. The output end of the cylinder 6 is connected to the scissor frame 8 through a piston rod 13. The top of the scissor frame 8 is connected to the bottom of the second conveyor roller 7. The cylinder 6 is electrically connected to the controller through a solenoid valve. The controller is provided with an up button and a down button for convenient control.

[0025] In this invention, after the graphite box moves from the first conveyor roller 2 to the second conveyor roller 7 on one side, the piston rod 13 is extended by the cylinder 6, which causes the scissor frame 8 to unfold, thereby realizing the lifting action and raising the graphite box on the second conveyor roller 7 to the designated position.

[0026] In this invention, a graphite box containing powder is placed on a first conveyor roller 2 and transported horizontally. After moving to a second conveyor roller 7 on one side, a cylinder 6 drives a piston rod 13 to extend, causing the scissor frame 8 to unfold, thereby achieving a lifting action. This raises the graphite box on the second conveyor roller 7 to a designated position, and then pushes it to move into the sintering furnace. Unloading is the reverse process. Automatic feeding and unloading replace cumbersome manual operations, reducing manpower requirements, labor intensity, and labor costs. This makes the production process smoother and more efficient, while also reducing safety hazards caused by manual operation and improving the safety of the production process.

[0027] In this utility model, a sliding groove 11 is provided at the bottom of the lifting frame 5. One end of the bottom of the scissor frame 8 is connected to the sliding groove 11 through a slider 12. When the scissor frame 8 is unfolded and retracted, the slider 12 slides in the sliding groove 11, providing stable guidance and support, so that the scissor frame 8 will not shake or deviate due to uneven force during the lifting process.

[0028] In this invention, the second conveying roller 7 has second rollers 10 evenly distributed inside. Then, the graphite box is pulled by an external force, and at the same time, the second rollers 10 are rotated to move the graphite box into the sintering furnace for sintering. The unloading is the reverse.

[0029] In this invention, automatic feeding and unloading replace cumbersome manual operations, reducing manpower requirements, labor intensity and labor costs, making the production process smoother and more efficient, while reducing safety hazards caused by manual operation.

[0030] In this invention, the first frame 1 and the second frame 4 are moved to one side of the sintering furnace via casters 9. A graphite box containing powder is placed on the first conveyor roller 2. An external force drives the graphite box, and as the first roller 3 rotates, the graphite box is moved to the second conveyor roller 7 on one side. Then, the piston rod 13 is extended by the cylinder 6, causing the scissor frame 8 to unfold, thereby achieving a lifting action. This raises the graphite box on the second conveyor roller 7 to the designated position. Then, an external force pulls the graphite box, and as the second roller 10 rotates, the graphite box is moved into the sintering furnace for high-temperature sintering. Unloading is the reverse process. Automatic feeding and unloading replace cumbersome manual operations, reducing manpower requirements and labor costs, making the production process smoother and more efficient. At the same time, it reduces safety hazards caused by manual operation and improves the safety of the production process.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
