The bearing plates 4 loaded with workpieces can be stacked on the top of the movable seat 8, and through the three-section rails 9 on both sides of the movable seat 8, the movable seat 8 can be moved inside the U-shaped seat 7, facilitating the pulling out or pushing in of the stacked bearing plates 4 from the left side of the frame 2 to a position corresponding to the conveyor belt 3. Workers do not need to directly place workpieces on the conveyor belt 3 or operate at the feeding end position of the high-temperature sintering furnace body 1, improving safety.

[0024] Embodiment 2:

[0025] A feeding mechanism for a sintering furnace, wherein the feeding rack 5 includes an L-shaped mounting plate 10, a support rod 11, and a mounting plate 12. The support rods 11 are equidistantly arranged on the left side of the L-shaped mounting plate 10. The outer side of the support rod 11 is fixedly connected to the mounting plate 12. In the middle of the outer side of the mounting plate 12, a telescopic cylinder 13 is fixedly connected. A connection port 14 is provided through the left inner wall of the L-shaped mounting plate 10. Inside the connection port 14, a feeding plate 15 is movably connected. The fixed end of the telescopic cylinder 13 penetrates the inner side of the mounting plate 12, and the movable end is fixedly connected to the middle of the left side of the feeding plate 15. A material taking seat 16 is connected to the outer side of the feeding plate 15. Electromagnets 17 are equidistantly embedded and fixed on the outer side of the material taking seat 16. The outer side of the electromagnet 17 is flush with the outer side of the connection port 14.

At the same time, the electromagnets 17 are started, so that the electromagnets 17 are magnetically adsorbed and fixed to the left side of the bearing trays 4. Then, the adsorbed and fixed bearing trays 4 are automatically sent onto the conveyor belt 3, and the stacked bearing trays 4 can be successively placed on the conveyor belt 3 for feeding operation, without the need for workers to manually carry and place the bearing trays 4 with workpieces one by one on the conveyor belt 3.

[0026] Embodiment 3:

[0027] A feeding mechanism for a sintering furnace, wherein a servo motor 18 is fixed in the middle of the top side of the feeding plate 15. A rectangular groove 19 is dug in the middle of the outer side of the feeding plate 15. The bottom side of the inner wall of the rectangular groove 19 is connected by a bearing to a lead screw 20. The output shaft of the servo motor 18 is fixedly connected to the top end of the lead screw 20. Guide rods 21 are arranged on both sides of the lead screw 20. Both ends of the guide rod 21 are fixedly connected to the inner wall of the rectangular groove 19. A lifting block 22 is sleeved on the outer sides of the guide rod 21 and the lead screw 20.

Inside the lifting block 22, a nut is connected by a ball bearing, and is threadedly connected to the lead screw 20 through the ball bearing and the nut. When lifting and loading the stacked bearing trays 4 one by one, the servo motor 18 can be started. The output shaft of the servo motor 18 drives the lead screw 20 to rotate, so that the lead screw 20 drives the connected lifting block 22 on the outer side to lift the material taking seat 16 adsorbed with the bearing tray 4 to the horizontal position of the conveyor belt 3. Then, the telescopic cylinder 13 is controlled to send the adsorbed bearing tray 4 onto the conveyor belt 3. It can not only adsorb and grab the bearing trays 4 at different heights, but also the workpieces sintered inside the sintering furnace body 1 can be successively adsorbed and fixed by the material taking seat 16 and re-stacked on the bearing table 6, greatly improving the automation of the overall equipment, avoiding that the sintered workpieces cannot be directly taken by workers, and further improving the working efficiency of material taking and feeding of the overall device.

[0028] In summary, when this device is in use, the carrier plate 4 loaded with workpieces can be stacked on the top of the movable seat 8. Through the three-section rails 9 on both sides of the movable seat 8, the movable seat 8 can be moved within the U-shaped seat 7, facilitating the pulling out or pushing in of the stacked carrier plates 4 from the left side of the frame 2 to a position corresponding to the conveyor belt 3. By starting the telescopic cylinder 13, the movable end of the telescopic cylinder 13 drives the feeding plate 15 to approach the left side of the stacked carrier plates 4. At the same time, the electromagnet 17 is started to magnetically adsorb and fix the left side of the carrier plate 4. Then, the adsorbed and fixed carrier plate 4 is automatically fed onto the conveyor belt 3. When individually lifting and loading the stacked carrier plates 4, the servo motor 18 can be started. The output shaft of the servo motor 18 drives the lead screw 20 to rotate, causing the lead screw 20 to drive the externally connected lifting block 22 to lift the material taking seat 16 adsorbed with the carrier plate 4 to the horizontal position of the conveyor belt 3. Then, the telescopic cylinder 13 is controlled to feed the adsorbed carrier plate 4 onto the conveyor belt 3. It can not only adsorb and grasp the carrier plates 4 at different heights, but also the workpieces sintered inside the sintering furnace body 1 can be successively adsorbed and fixed by the material taking seat 16 and re-stacked on the bearing table 6.
