Technical Field

[0001] The invention relates to the technical field of silicon nitride powder spreading and compacting devices, in particular to a silicon nitride powder spreading and compacting device. Background Art

[0002] Silicon nitride has a series of excellent thermophysical properties such as good thermal shock resistance, oxidation resistance, high temperature resistance, corrosion resistance, high chemical stability, and high strength. It is an excellent high-temperature structural material. In the preparation process of silicon powder nitridation, it is necessary to spread and compact the powder on the bottom of the crucible.

[0003] Patent announcement number CN219903505U discloses a silicon nitride powder compacting device, including a device bottom plate, a compacting mechanism is arranged on the top of the device bottom plate; the compacting mechanism includes an electric telescopic cylinder, a fixed shell, a double-headed motor, a first motor shaft, a second motor shaft, an exhaust fan blade and a compacting plate; the top of the device bottom plate is bolted to a fixed frame plate, the middle of the bottom end of the fixed frame plate is bolted to an electric telescopic cylinder, and the bottom of the electric telescopic cylinder is bolted to a fixed shell. This patent uses a double-headed motor in a fixed shell to not only use the double-headed motor to drive the compacting plate to rotate and compact during the compacting of silicon nitride powder by the compacting plate, but also can move the compacting plate upward during the rotation of the double-headed motor, and through the rotation of the exhaust fan blade, the external floating dust is sucked into the fixed shell to collect the dust, and the rotation of the exhaust fan blade does not require additional driving equipment, saving energy.

[0004] In the above patent, the compacting plate can be moved upward, and the dust floating outside is sucked into the fixed shell through the rotation of the exhaust fan blades to collect the dust. In addition, the rotation of the exhaust fan blades does not require additional driving equipment, which saves energy. However, during the pressing process, the material may stick to the bottom of the extrusion block. Each time it is used, the material may stick to the bottom of the extrusion block, which will cause the material at the bottom of the extrusion block to gradually increase, affecting the next pressing, causing the shape of the extruded material to change, and the extruded material to be unqualified and wasteful.

The other end of the rack is slidably installed inside the sliding groove to limit the sliding direction of the rack.

[0014] The present invention provides a silicon nitride powder compacting device, which has the following beneficial effects:

[0015] (1) In the present invention, when the electric push rod is started, it will push the cutting block to cut the compacted material, and the scraper will move and contact the lower surface of the extrusion block. The contact between the scraper and the lower surface of the extrusion block will clean the material stuck to the lower surface of the extrusion block and store the material in the collection box. The contact between the rotating plate and the blocking rod will push the rotating plate to rotate. The rotation of the rotating plate will push the L-shaped rod. When the L-shaped rod is pushed, it will drive the collection box to rotate. The rotation of the collection box will pour the collected material into the collection trough. The material attached to the surface of the extrusion block is collected and poured into the collection trough, which can effectively utilize the material and avoid waste. At the same time, it can prevent the material from accumulating too much on the surface of the extrusion block, which will cause the shape of the material to change when the material is extruded, resulting in material waste.

[0016] (2) In this invention, the rotation of the rotating plate will drive the slider to slide inside the arc groove. The sliding of the slider will press the sliding rod to move. The movement of the sliding rod will press the connecting rod to move. The movement of the connecting rod will press the pressing plate to move. The movement of the pressing plate will press the second semicircular plate to move. The movement of the second semicircular plate will be blocked by the main body. At this time, the first spring will accumulate force. When the second semicircular plate moves to the top of the pressing port, the first spring will push the second semicircular plate out to press the material inside the pressing port. The movement of the pressing plate will drive the movement of the first semicircular plate. The movement of the pressing rod will discharge the gas inside the cylinder. The gas will enter the nozzle through the air pipe and then be discharged from the air outlet on the nozzle to blow the material attached to the surface of the main body through the square groove. When the No. 2 semicircular plate moves above the pressing port, the force collected by the No. 1 spring will be released to pre-press the material in the pressing port and discharge excess air in the material, so that when the material is formally pressed later, there will be no material flying out due to excessive air in the material and affecting the pressing. When the air is ejected from the nozzle, it will blow the material attached to the surface of the main body through the square groove and blow it into the pressing port to fully use the material without waste.

[0017] (3) In the invention, the opening and closing plate is intermittently opened and closed so that the material intermittently enters the feed trough. The rotation of the square plate will contact the vibration rod. The contact between the square plate and the vibration rod will push the vibration rod to slide downward. When the vibration rod is not in contact with the square plate, the vibration rod will be pulled back by the No. 2 spring so that the square block hits the inside of the feed trough to clear the material. When the opening and closing plate is intermittently opened and closed, the material will slowly enter the feed trough so that the material will not be blocked. The impact of the vibration rod on the inside of the feed trough can further clear the feed trough so that the material will not accumulate. BRIEF DESCRIPTION OF THE DRAWINGS

The contact between the square rod 708 and the rack 701 will push the rack 701 to slide inside the slide groove. When the rack 701 slides, it drives the gear shaft 702 to rotate. The rotation of the gear shaft 702 drives the square plate 705 to rotate. The rotation of the square plate 705 will disperse the material. The rotation of the square plate 705 will contact the bevel rod 706. The contact between the square plate 705 and the bevel rod 706 When the square plate 705 is not in contact with the bevel rod 706, the opening and closing plate 707 is rebounded to its original position by the torsion spring, and the opening and closing plate 707 is intermittently opened and closed, so that the material can intermittently enter the feed trough 7. The rotation of the square plate 705 will contact the vibration rod 704. The contact between the square plate 705 and the vibration rod 704 will push the vibration rod 704 to slide downward. When the vibration rod 704 is not in contact with the square plate 705, the vibration rod 704 will be pulled back by the No. 2 spring to make the square hit the inside of the feed trough 7 to clear the material.
