[0002] With the rapid development of the pet industry and the increasing number of cat owners, the market demand for cat litter, as a daily necessity for cats, is also expanding. To meet market demand, cat litter manufacturers need to improve production efficiency and achieve large-scale mass production. This requires the use of more efficient pelletizing equipment. Ring die pelletizing equipment, due to its high production efficiency and good pellet forming effect, has become one of the preferred equipment for cat litter manufacturers.

[0003] Existing devices primarily produce cat litter granules using a ring die and extrusion assembly. Many existing technologies resemble a ring die pellet mill for cat litter production. The structure of patent CN222855341U includes a base plate, with a first L-shaped plate fixedly connected to the top left center of the base plate. A slide rail is provided on the top inner wall of the first L-shaped plate. An electric push rod is fixedly connected to the left center of the first L-shaped plate, and the output end of the electric push rod passes through and is fixedly connected to a first fixing plate. A second L-shaped plate is fixedly connected to the right center of the base plate. This invention can dry the raw materials and release water vapor in a timely manner; however, there are still areas for improvement in this device.

[0004] Existing equipment mainly uses drive components and pressure rollers inside the ring die for extrusion granulation. This results in limited usable space inside the ring die, making it difficult for cat litter raw materials to quickly enter the pressure rollers' range of motion for extrusion granulation. Furthermore, some devices struggle to cut cat litter granules to a fixed length and guide them out of the granulation bin, leading to granule accumulation and affecting litter formation, thus reducing the equipment's efficiency and practicality. Therefore, to address these issues, a ring die granulation device for cat litter production is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a ring die pelletizing device for cat litter production, addressing the problems mentioned in the background art. Existing devices primarily rely on assembling a drive assembly and pressure rollers inside the ring die for pelletizing, resulting in limited usable space within the die and hindering the rapid entry of cat litter raw materials into the pressure rollers for pelletizing. Furthermore, some devices struggle to cut cat litter particles to a fixed length and guide them out of the pelletizing bin, leading to particle accumulation and affecting litter formation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ring die pelletizing device for cat litter production, comprising a pellet discharge bin, a ring die body fixedly assembled in the middle of the discharge bin, a material preparation bin fixedly connected to the top of the ring die body, a pelletizing mechanism provided inside the discharge bin, a rotating ring frame limited and sleeved on the lower outer wall of the material preparation bin, discharge components fixedly connected to the bottom two sides of the rotating ring frame, a support frame fixedly connected to the top right side of the discharge bin, a discharge mechanism provided inside the support frame, and a control console fixedly connected to the front of the discharge bin.

The outer wall of the pressure roller is close to the inner wall of the ring die body, and a material distribution plate is fixedly connected to the outer wall of the rotating main shaft between adjacent pressure rollers.

[0009] Preferably, the discharge mechanism includes a second motor, the left side of which is fixedly connected to the upper right side of the support frame, and a transmission shaft is fixedly connected to the middle left side of the second motor. The left end of the transmission shaft passes through the support frame and is fixedly connected to a first bevel gear.

[0010] Preferably, the left side of the first bevel gear is meshed with a second bevel gear, and the bottom of the second bevel gear is fixedly connected to the top of the rotating ring frame.

[0011] Preferably, the material discharge assembly includes a rotating rod, the top end of which is fixedly connected to both sides of the bottom of the rotating ring frame, and a scraper is fixedly connected to the outer wall of the rotating rod, the scraper being tangent to the outer curved surface of the ring mold body.

[0012] Preferably, a discharge plate is fixedly connected to the outer wall of the rotating rod, and the discharge plate is perpendicular to the outer curved surface of the ring die body.

[0019] The pelletizing mechanism 2 includes a first motor 21, the top of which is fixedly connected to the bottom center of the pelleting hopper 11. A drive shaft 22 is fixedly connected to the top center of the first motor 21, and the top end of the drive shaft 22 passes through the bottom plate of the pelleting hopper 11 and is fixedly connected to a rotating main shaft 23. This design enables the first motor 21 to drive the drive shaft 22 and the rotating main shaft 23 to rotate in a limited position. A rotating frame 24 is fixedly connected to the top end of the rotating main shaft 23, and a pressure roller 25 is movably connected to the bottom outer ring of the rotating frame 24. The outer wall of the pressure roller 25 is close to the inner wall of the ring die body 12, and a material distribution plate 26 is fixedly connected to the outer wall of the rotating main shaft 23 between adjacent pressure rollers 25. This design enables the rotating main shaft 23 to drive the material distribution plate 26 to rotate synchronously, allowing the material distribution plate 26 to guide the raw material in the middle of the ring die body 12 into the range of motion of the pressure roller 25. At the same time, rotating the main shaft 23 can drive the rotating frame 24 and the pressure roller 25 to rotate synchronously, so that the pressure roller 25 can work with the ring die body 12 to granulate the cat litter raw material.

[0020] The discharge mechanism 3 includes a second motor 31. The left side of the second motor 31 is fixedly connected to the upper right side of the support frame 16. A drive shaft 32 is fixedly connected to the middle left side of the second motor 31. The left end of the drive shaft 32 passes through the support frame 16 and is fixedly connected to a first bevel gear 33. This design enables the second motor 31 to drive the drive shaft 32 and the first bevel gear 33 to rotate in a limited position. A second bevel gear 34 is meshed with the left side of the first bevel gear 33. The bottom of the second bevel gear 34 is fixedly connected to the top of the rotating ring frame 14. This design enables the first bevel gear 33 to mesh and drive the second bevel gear 34 and the rotating ring frame 14 to rotate in a limited position, so that the rotating ring frame 14 drives the discharge assembly 15 to rotate synchronously.

[0021] The discharge assembly 15 includes a rotating rod 35, the top of which is fixedly connected to both sides of the bottom of the rotating ring frame 14.

The first motor 21 drives the drive shaft 22 to rotate in a limited position. The drive shaft 22 drives the rotating main shaft 23 to rotate synchronously. The rotating main shaft 23 drives the material distribution plate 26 to rotate synchronously, so that the material distribution plate 26 guides the cat litter raw materials located in the middle to the range of motion of the pressure roller 25. At the same time, the rotating main shaft 23 can drive the rotating frame 24 to rotate. The rotating frame 24 drives the pressure roller 25 to rotate synchronously, so that the pressure roller 25 can cooperate with the ring die body 12 to extrude and granulate the cat litter raw materials, thus realizing the granulation operation of the raw materials.

[0023] When it is necessary to cut and discharge the raw materials, the second motor 31 is first started through the control console 17. The second motor 31 drives the transmission shaft 32 to rotate in a limited position. The transmission shaft 32 drives the first bevel gear 33 to rotate synchronously. The first bevel gear 33 meshes with and drives the second bevel gear 34 to rotate. The second bevel gear 34 drives the rotating ring frame 14 to rotate in a limited position. The rotating ring frame 14 drives the rotating rod 35 to rotate synchronously. The rotating rod 35 drives the scraper 36 to rotate against the outer wall of the ring mold body 12, so that the scraper 36 cuts the cat litter particles. At the same time, the rotating rod 35 and the discharge plate 37 rotate synchronously, so that the discharge plate 37 guides the cat litter particles to be discharged from the pellet hopper 11, thus realizing the cutting and discharge operation of the raw materials.
