A discharge part is installed at the front end of the machine body 1. The lower part of the discharge part is fixedly connected to a sealing box 12. A feeding hopper 19 is fitted on the lower end of the sealing box 12. The feeding hopper 19 can push the ceramic powder into the forming die 3 to complete the feeding. At the same time, it can also scrape the ceramic powder in the forming die 3 flat to facilitate subsequent pressing. The feeding hopper 19 is slidably installed at the lower end of the machine body 1. A sieve seat 17 is arranged inside the sealing box 12. The sealing box 12 can cover the sieve seat 17 to prevent the ceramic powder from scattering. Rollers 22 are rotatably installed on both sides of the discharge part. The sieve seat 17 can remove lumps in the ceramic powder. The ends of the two roller shafts 22 are inlaid with push ears 29. The roller shafts 22 drive the push ears 29 to rotate. The ends of the push ears 29 are connected to push racks 31. The ends of the push racks 31 are connected to H-shaped swing seats 33. The push ears 29 can drive the push racks 31 to move to push the H-shaped swing seats 33. The H-shaped swing seats 33 are slidably connected to the discharge piece. The H-shaped swing seats 33 are connected to the sieve seat 17. The outer surface of one of the roller shafts 22 is coaxially inlaid with a gear 28. The rear part of the gear 28 is meshed with a tooth plate 26. The gear 28 and the tooth plate 26 drive the roller shaft 22 to rotate. The tooth plate 26 is connected to the forming piece.

[0026] A connecting frame 25 is fixedly installed on the side of the feeding hopper 19, and guide rods 24 are fixedly installed at both ends of the connecting frame 25. The connecting frame 25 serves to fix the guide rod 24 and the feeding hopper 19 together. A guide sleeve 23 is slidably installed on the outer surface of the guide rod 24. The guide rod 24 and the guide sleeve 23 serve to guide the feeding hopper 19. The guide sleeve 23 is fixed to the lower end of the inner part of the body 1.

[0027] The front and rear ends of the H-shaped swing seat 33 are fixedly installed with a synchronous frame 15, and the synchronous frame 15 slides through the interior of the sealing box 12. The synchronous frame 15 can allow the H-shaped swing seat 33 and the sieve seat 17 to move synchronously. The front and rear end surfaces of the sieve seat 17 are provided with T-shaped slots 18, and a T-shaped seat 16 is slidably installed inside the T-shaped slots 18. The end of the synchronous frame 15 is fixed to the T-shaped seat 16. By pulling the sieve seat 17, the T-shaped seat 16 can be driven to slide in the T-shaped slots 18, so that the sieve seat 17 can be pulled out from the sealing plate 13, so as to clean the ceramic powder agglomerated on the sieve seat 17.

[0028] An upper connecting shaft 30 is rotatably installed on one end of the pushing frame 31, and the end of the upper connecting shaft 30 is fixed to the pushing ear 29. A lower connecting shaft 32 is rotatably installed on the other end of the pushing frame 31. Both the upper connecting shaft 30 and the lower connecting shaft 32 serve to facilitate the connection of the pushing frame 31. The end of the lower connecting shaft 32 is fixed to the H-shaped swing seat 33. A sealing plate 13 is provided on the side of the sealing box 12. The rear edge of the side of the sealing plate 13 is hinged to the sealing box 12, and the sealing plate 13 can seal the sealing box 12.

[0029] A lock sleeve 6 is fixedly installed at the front edge of the side of the sealing plate 13, and a lock rod 8 is coaxially arranged inside the lock sleeve 6. The lock sleeve 6 plays a role in supporting the lock rod 8. Both ends of the lock rod 8 pass through the front and rear ends of the lock sleeve 6. The lock rod 8 and the lock sleeve 6 are slidably matched. A rod sleeve 11 is fixedly installed at the front edge of the side of the sealing box 12. The front part of the lock rod 8 is inserted into the inside of the rod sleeve 11. The rod sleeve 11 and the lock rod 8 are inserted, which can fix the sealing plate 13 and prevent it from rotating. The outer surface of the lock rod 8 is coaxially inlaid with a spring cap 10, which fits the inside of the lock sleeve 6. The spring cap 11 0 plays the role of being pushed by the locking spring 7. The locking spring 7 is wound around the outer side of the locking rod 8. One end of the locking spring 7 is fixed to the spring cap 10. The locking spring 7 can push the locking rod 8 so that the locking rod 8 is inserted into the rod sleeve 11. The other end of the locking spring 7 is fixed to the inner rear end of the locking sleeve 6. The rear end of the locking rod 8 is fixedly installed with a rod ring 9. By pulling the rod ring 9, the locking rod 8 can be moved backward and the locking rod 8 can be separated from the rod sleeve 11, so that the sealing plate 13 can be rotated to open without the restriction of the locking rod 8, so that the sieve seat 17 can be drawn out from the sealing plate 13.

[0030] The discharge part includes a storage hopper 4 fixedly mounted on the front end of the machine body 1. The storage hopper 4 plays the role of placing ceramic powder. The lower end of the storage hopper 4 is fixedly connected with a Y-shaped hopper 14. The Y-shaped hopper 14 can gather the ceramic powder so that the ceramic powder can fall on the middle of the sieve seat 17. When the subsequent sieve seat 17 swings horizontally, the ceramic powder can still fall on the sieve seat 17. The lower end of the Y-shaped hopper 14 is fixedly connected with the middle of the upper end of the sealing box 12. Two roller shafts 22 penetrate into the interior of the storage hopper 4 from both sides of the storage hopper 4 respectively. The roller shaft 22 rotates with the storage hopper 4. A discharge roller 20 is coaxially inlaid between the opposite surfaces of the two roller shafts 22. The roller shaft 22 drives the discharge roller 20 to rotate. The discharge roller 20 is attached to the middle of the storage hopper 4. The outer surface of the discharge roller 20 is provided with three material troughs 21 in a circular array. The material troughs 21 on the discharge roller 20 can continuously send the ceramic powder in the storage hopper 4 downward, so that the ceramic powder can fall on the sieve seat 17 in small quantities. The outer surface of the H-shaped pendulum seat 33 is slidably mounted with a seat guide shell 34. The seat guide shell 34 serves to horizontally guide the H-shaped pendulum seat 33. The side of the seat guide shell 34 is fixedly mounted with a shell block 35. The shell block 35 serves to fix the seat guide shell 34. The end of the shell block 35 is fixed to the storage hopper 4.

[0031] The molding part includes a hydraulic cylinder 5 installed through the upper end of the interior of the body 1, and a molding punch 2 is fixedly installed at the output end of the hydraulic cylinder 5. The hydraulic cylinder 5 can drive the molding punch 2 to move downward to press the ceramic powder in the molding die 3 to form it. The molding punch 2 is slidably connected to the body 1, and a molding die 3 is arranged below the molding punch 2. The molding die 3 is embedded in the lower end of the interior of the body 1. The upper end surface of the molding die 3 is coplanar with the lower end surface of the interior of the body 1, which can facilitate the feeding hopper 19 to slide on the body 1 to push the ceramic powder into the molding die 3 and scrape the ceramic powder in the molding die 3 flat.

[0032] A connecting frame 27 is fixedly mounted on the upper end of the tooth plate 26 , and an end of the connecting frame 27 is fixed to the output end of the hydraulic cylinder 5 . The connecting frame 27 serves to connect the tooth plate 26 and the hydraulic cylinder 5 .

[0033] During molding, the feeding hopper 19 is pushed to push the ceramic powder into the molding die 3 through the moving feeding hopper 19. During this process, the guide rod 24 slides in the guide sleeve 23 to guide the feeding hopper 19. After the feeding is completed, the feeding hopper 19 is pushed to reset. At this time, the feeding hopper 19 will scrape the ceramic powder in the molding die 3 during the reset process. Then the hydraulic cylinder 5 works to drive the molding punch 2 to move downward to press the ceramic powder in the molding die 3 to form it. During this process, the tooth plate 26 will be synchronously driven to move downward. At this time, the downward tooth plate 26 drives the discharge roller 20 on the roller shaft 22 to rotate through the gear 28, so as to continuously discharge the stored material through the material trough 21 on the discharge roller 20. The ceramic powder in the bucket 4 is sent downward, so that the ceramic powder can continuously fall on the sieve seat 17 in small quantities. At the same time, the rotating roller 22 will also drive the push ear 29 to rotate, and then drive the push frame 31 to move, so as to push the H-shaped swing seat 33, so that the H-shaped swing seat 33 can slide back and forth in the seat guide shell 34, thereby driving the sieve seat 17 to swing horizontally in the sealing box 12 through the synchronous frame 15, so as to screen the ceramic powder on the sieve seat 17 and remove the agglomerated ceramic powder. The removed ceramic powder falls into the feeding hopper 19, so as to ensure that the particle size of the pressed ceramic powder is in a small particle size state, so that the ceramic powder can be tightly combined after pressing, so as to improve the strength of the pressed ceramic product.
