Description

Technical Field

[0001] This utility model relates to the field of material crushing and processing technology, and in particular to a calcination treatment device for a mixture of stainless steel powder and resin. Background Technology

[0002] Stainless steel powder and resin mixtures are widely used in metallurgy, additive manufacturing, and other fields. These materials require calcination to remove resin and densify the metal powder. Before calcination, the stainless steel waste and resin mixture needs to be pulverized. This pulverization process is a fundamental preliminary step, and its effectiveness directly affects the quality and efficiency of subsequent processes such as mixing, injection molding, and calcination.

[0003] Currently, most crushing and processing equipment is equipped with screens to screen and separate materials that do not meet the particle size requirements, ensuring that the crushed particle size meets the standards. However, during long-term operation, some materials tend to clog the screen mesh, which affects the screening efficiency of the screen. Moreover, cleaning the materials clogging the screen mesh often relies on manual tools, which requires stopping the equipment operation. This not only consumes manpower and time costs but also seriously affects the continuity of production and the operating efficiency of the equipment, greatly reducing the application effectiveness of the crushing and processing equipment in actual production.

There are two fixing plates 406, and the two fixing plates 406 are respectively fixedly connected to the support legs on the left and right sides of the bottom of the crushing box 1. Two guide rods are fixedly connected to the upper end face of each fixing plate 406. The guide slide rod 405 is slidably connected to four slide cylinders 404 respectively.

[0038] Example 2, based on Example 1, such as Figure 5 and Figure 7As shown, each vertical guide rod 507 is slidably connected to a guide sleeve on its outside, and the guide sleeve is fixedly connected to the bottom surface of the horizontal support plate 102. This allows the vertical guide rod 507 and the lifting frame 501 to receive effective guidance when moving up and down, making the vertical guide rod 507 and the lifting frame 501 move more smoothly and improving the reliability of the hammer 502 in the striking operation.

[0039] The working principle of this embodiment is as follows: In use, the crushing motor 202 and grinding motor 302 are first started via the control box 103. The crushing motor 202 drives the first worm, the first worm wheel, and a crushing roller 201 on the right side to rotate counterclockwise. Then, the two first synchronous gears 203 drive the crushing roller 201 on the left side to rotate clockwise. Next, the grinding motor 302 drives the second worm, the second worm wheel, and a grinding roller 301 on the right side to rotate clockwise. Then, the two second synchronous gears 303 drive the grinding roller 301 on the left side to rotate counterclockwise. Afterward, the stainless steel waste and resin mixture (hereinafter referred to as "material") is fed into the feed hopper 101, and then... The crushing roller 201 performs preliminary crushing of the material. The crushed material falls onto the upper part of the two grinding rollers 301. Then, the two grinding rollers 301 carry the crushed material to the inner arc surface of the two arc-shaped grinding blocks 104. The two arc-shaped grinding blocks 104 cooperate with the two outwardly rotating grinding rollers 301 to further grind the crushed material. The ground material particles are discharged downward through the discharge port 106 and then fall into the screening box 401. The screen 403 inside the screening box 401 screens the ground material particles. The material with a particle size that does not meet the requirements remains inside the screening box 401, while the material with a particle size that meets the requirements falls downward into the guide box 402.

[0040] During the abrasive process, the striking motor 505 is started via the control box 103, causing a rear rotating shaft 503 and a rear synchronous pulley 506 to rotate. Then, a synchronous belt drives a front synchronous pulley 506 and a front rotating shaft 503 to rotate. As the two rotating shafts 503 rotate, they also drive two cams 504 to rotate. When the raised end of the cam 504 rotates downwards, it pushes the lifting frame 501 downwards. At this time, the external spring of the vertical guide rod 507 is compressed. Then, when the raised end rotates upwards, the lifting frame 501 loses its downward pushing force. Under the elastic force of the external spring of the vertical guide rod 507, the lifting frame 501 moves rapidly upward with the striking hammer 502, causing the striking hammer 502 to strike the bottom of the collision plate 407. The two striking hammers 502 strike the two collision plates 407 respectively, thereby giving the guide box 402, the screening box 401 and the screen 403 an upward impact force. At this time, the guide box 402, the screening box 401 and the screen 403 will vibrate. Under the upward impact force and vibration, the material blocked in the mesh of the screen 403 is forced to fall out, thereby improving the screening efficiency of the screen 403.
