Description

Technical Field

[0001] This invention relates to the field of cat litter preparation technology, specifically to a high-efficiency maturation and granulation device. Background Technology

[0002] Plant-based cat litter made from soybean residue, corn flour, tapioca flour, and other raw materials is the fastest-growing cat litter category globally in recent years. It has gained popularity among many cat owners due to its environmental friendliness, flushability, and dust-free properties. The processing often involves steps such as curing and pelleting.

[0003] Chinese patent application CN118384787A discloses a ring die pelleting mechanism and a method for producing biological feed, including a feeder, a modulator, and a ring die pelletizer. The discharge end of the feeder is connected to the feed end of the modulator, and the discharge end of the modulator is connected to the ring die pelletizer through a feeding channel. The ring die pelletizer includes: an annular fixed shell and a ring die disposed within the annular fixed shell, the ring die being driven to rotate by a drive source; at least two scraper mechanisms penetrating the annular fixed shell and capable of directional sliding relative to the annular fixed shell; an annular cover rotatably mounted on the annular fixed shell and connected to the scraper mechanisms, the annular cover having an inclined guide groove, and a cylindrical rod connected to the scraper mechanisms being slidably mounted within the inclined guide groove; and an adjustment mechanism disposed at the side end of the annular fixed shell for adjusting the rotation of the annular cover and locking the position of the annular cover after adjustment. This achieves the same distance adjustment between multiple scraper mechanisms and the ring die, ensuring uniform pelleting. However, this pelleting mechanism and the prior art still have the following problems: 1. After prolonged operation, the distance between the pressure roller and the ring die is prone to change. When the distance between the two is too large, it will cause the pressure roller to slip, thereby reducing the pelletizing efficiency of the pressure roller, and the material is also prone to getting stuck between the pressure roller and the ring die. 2. The inner surface of the ring die is easily damaged by long-term friction with the pressure roller, which leads to deformation of the extrusion hole. The cost of replacing or repairing the entire ring die is high.

[0004] Based on this, the present invention designs a high-efficiency maturation and granulation device to solve the above problems. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a high-efficiency maturation and granulation device.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A high-efficiency maturation and granulation device includes a modulator and a granulator, wherein the discharge end of the modulator is connected to the feed end of the granulator through a discharge channel; The pelletizer includes a fixed housing, a modular ring die mechanism, an anti-slip pelletizing mechanism, and a synchronously adjustable pelletizing mechanism. The fixed housing is fixedly installed at the lower end of the modulator. The modular ring die mechanism is located inside the fixed housing and is driven to rotate by a drive device. The anti-slip pelletizing mechanism is installed on the housing of the drive device and is used to cut off the material leaving the modular ring die mechanism. An anti-slip pelletizing mechanism is installed on the inner side of the modular ring die mechanism. The anti-slip pelletizing mechanism includes a mounting frame, movable pelletizing components, a continuous drive component, and a spacing adjustment component. The mounting frame is fixedly connected to the housing of the drive device. Multiple movable pelletizing components that cooperate with the modular ring die mechanism are evenly installed in a circumferential array on the mounting frame. The movable pelletizing components can move radially along the modular ring die mechanism. The continuous drive component is installed in the middle of the mounting frame and is used to control the synchronous movement of all movable pelletizing components. A continuous drive component is also installed on the outer side of the modular ring die mechanism. The continuous drive component is used to drive the movable pelletizing components to rotate when the modular ring die mechanism rotates.

[0007] Furthermore, the continuous drive assembly includes a driving gear ring, a driven gear, and a connecting frame. The driving gear ring is fixedly connected to the outer side of the modular ring die mechanism. Multiple connecting frames corresponding to the pressure rollers are fixedly installed on the mounting frame. The connecting frame is rotatably mounted with a driven gear through a bearing, and the driven gear meshes with the driving gear ring.

[0008] Furthermore, the continuous drive assembly also includes a universal coupling, through which the driven gear is connected to the rotating shaft.

[0009] Furthermore, the spacing adjustment assembly includes an adjustment shaft, connecting rods, and a locking assembly. The adjustment shaft is rotatably connected to the mounting frame via bearings. Several connecting rods, each corresponding to a movable frame, are arranged in a circumferential array on the outside of the adjustment shaft. The two ends of the connecting rods are hinged to the adjustment shaft and the movable frame, respectively. The locking assembly is installed between the mounting frame and the adjustment shaft to fix the two relatively.

[0010] Furthermore, the modular ring mold mechanism includes an outer ring mold, an inner ring mold, an outer slot, an outer insert block, and an inner slot. Multiple inner ring molds are arranged in a circular array on the inner side of the outer ring mold. An outer insert block is fixedly installed at the outer end of each inner ring mold, and an outer slot that mates with the outer insert block is opened at the outer end of the outer ring mold. An inner insert block is fixedly installed at the inner end of each inner ring mold, and an inner slot that mates with the inner insert block is opened at the inner end of the outer ring mold. A fixing pressure ring is also fixedly installed at the outer end of the outer ring mold, and the fixing pressure ring is fixedly connected to the driving gear ring. Furthermore, the outer ring mold and the inner ring mold have corresponding through holes, and the through holes of the inner ring mold are tapered.

[0011] Furthermore, the synchronously adjustable pelletizing mechanism includes a cutter, a straight rod, a connecting seat, and a depth adjustment assembly. Multiple cutters, each corresponding to a movable pelletizing assembly, are distributed between the fixed housing and the modular ring die mechanism. One end of the straight rod is fixedly connected to the cutter, and the other end of the straight rod is slidably connected to the connecting seat. The connecting seat is fixedly connected to the outer wall of the fixed housing. The depth adjustment assembly is installed on the outside of the fixed housing and is used to control all cutters to move synchronously along the radial direction of the modular ring die mechanism.

[0012] Furthermore, the depth adjustment assembly includes a synchronization control assembly and a control drive assembly installed on the outside of the fixed housing. The synchronization control assembly is connected to the straight rod, and the control drive assembly is drivenly connected to the synchronization control assembly.

[0013] Furthermore, the synchronization control component includes an active bevel gear and a driven bevel gear. The connecting seat is rotatably connected to the driven bevel gear via a bearing, and the driven bevel gear is threadedly connected to a straight rod. The active bevel gear is slidably mounted on the outer wall of the fixed housing along the circumference of the fixed housing, and the driven bevel gear is meshed with the active bevel gear.

[0014] Furthermore, the synchronization control component includes a fixed adjusting block, a movable adjusting block, and an adjusting screw. The movable adjusting block is rotatably connected to the active bevel gear disk, the fixed adjusting block is rotatably connected to the outer wall of the fixed housing, and the adjusting screw is rotatably connected to the fixed adjusting block through a bearing. The adjusting screw is also threadedly connected to the movable adjusting block.

[0015] Compared with the prior art, the beneficial effects of this invention are as follows: 1. In this invention, after the material is fed into the modulator for stirring and maturation, it enters the modular ring die mechanism. The driving device drives the modular ring die mechanism to rotate. Under the action of the continuous driving component, all movable pelletizing components rotate synchronously, squeezing the material into the modular ring die mechanism. The material squeezed out of the modular ring die mechanism then completes the pelletizing operation under the action of the synchronously adjustable pelletizing mechanism. The spacing adjustment component can control all movable pelletizing components to move synchronously along the radial direction of the modular ring die mechanism, adjusting the spacing between the movable pelletizing components and the modular ring die mechanism to meet the requirements of stable and efficient pelletizing.

[0016] 2. The outer ring die and the inner ring die have corresponding through holes, and the through hole of the inner ring die is conical. When any inner ring die is damaged, only the damaged outer ring die and the inner ring die need to be replaced to restore the performance of the ring die. The disassembly and assembly steps are simple and convenient, which is beneficial to the work of maintenance personnel.

[0017] 3. The outer ring die, inner ring die, and pressure roller rotate to perform pelleting. The pelleting operation is achieved by the cutter. By rotating the adjusting screw, the distance between the fixed adjusting blocks can be adjusted, allowing the active bevel gear disc to slide circumferentially along the fixed housing. This causes the active bevel gear disc to drive all the driven bevel gears to rotate. The connecting seat and the driven bevel gears work together to control the straight rod to move radially along the fixed housing under the limiting action of the connecting seat. This achieves synchronous adjustment of the distance between all cutters and the outer ring die, ensuring that the pellet length cut by each cutter is consistent, resulting in uniform specifications of the finished feed.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0023] In some embodiments, please refer to the accompanying drawings. Figures 1-12 A high-efficiency maturation and granulation device includes a modulator 1 and a granulator 2, wherein the discharge end of the modulator 1 is connected to the feed end of the granulator 2 through a discharge channel. The pelletizer 2 includes a fixed housing 5, a modular ring die mechanism 6, an anti-slip pelletizing mechanism 7, and a synchronously adjustable pelletizing mechanism 8. The fixed housing 5 is fixedly installed at the lower end of the modulator 1. The modular ring die mechanism 6 is located inside the fixed housing 5 and is driven to rotate by a drive device. The anti-slip pelletizing mechanism 7 is installed on the housing of the drive device and is used to cut off the material leaving the modular ring die mechanism 6. In this embodiment, the driving device includes an active motor 3 and a transmission box 4. The output end of the active motor 3 is fixedly connected to the input end of the transmission box 4, and the output end of the transmission box 4 is fixedly connected to the modular ring mold mechanism 6. An anti-slip pelletizing mechanism 7 is installed on the inner side of the modular ring die mechanism 6. The anti-slip pelletizing mechanism 7 includes a mounting frame 71, movable pelletizing components 72, a continuous drive component 73, and a spacing adjustment component 74. The mounting frame 71 is fixedly connected to the housing of the drive device. Multiple movable pelletizing components 72 that cooperate with the modular ring die mechanism 6 are evenly installed in a circumferential array on the mounting frame 71. The movable pelletizing components 72 can move radially along the modular ring die mechanism 6. The continuous drive component 73 is installed in the middle of the mounting frame 71 and is used to control the synchronous movement of all movable pelletizing components 72. The continuous drive component 73 is also installed on the outer side of the modular ring die mechanism 6 and is used to drive the movable pelletizing components 72 to rotate when the modular ring die mechanism 6 rotates. In this invention, the material is fed into the modulator 1 for stirring and maturation, and then enters the modular ring die mechanism 6. The driving device drives the modular ring die mechanism 6 to rotate. Under the action of the continuous driving component 73, all movable pelletizing components 72 rotate synchronously, squeezing the material into the modular ring die mechanism 6. The material squeezed out of the modular ring die mechanism 6 then completes the pelleting operation under the action of the synchronously adjustable pelletizing mechanism 8. The spacing adjustment component 74 can control all movable pelletizing components 72 to move synchronously along the radial direction of the modular ring die mechanism 6, and adjust the spacing between the movable pelletizing components 72 and the modular ring die mechanism 6 to meet the requirements of stable and efficient pelleting.

[0024] The movable pelletizing assembly 72 includes a movable frame 721, a pressure roller 722, and a rotating shaft 723. The movable frame 721 is mounted on the mounting frame 71 and can move radially along the modular ring die mechanism 6 via a limiting component. The rotating shaft 723 is rotatably connected to the movable frame 721 via a bearing, and the pressure roller 722 is fixedly connected to the rotating shaft 723. In this embodiment, the limiting component adopts a dovetail groove and dovetail block limiting structure.

[0025] Please see Figure 6 , Figure 7 , Figure 8 and Figure 9 The continuous drive assembly 73 includes a drive gear ring 731, a driven gear 732, a connecting frame 733, and a universal coupling 734. The drive gear ring 731 is fixedly connected to the outer side of the modular ring mold mechanism 6. Multiple connecting frames 733 corresponding one-to-one with the pressure rollers 722 are fixedly installed on the mounting frame 71. The driven gears 732 are rotatably mounted on the connecting frame 733 through bearings. The driven gears 732 are meshed with the drive gear ring 731, and the driven gears 732 are connected to the rotating shaft 723 through the universal coupling 734. The spacing adjustment assembly 74 includes an adjustment shaft 741, connecting rods 742, and a locking assembly. The adjustment shaft 741 is rotatably connected to the mounting frame 71 via bearings. Several connecting rods 742, each corresponding to a movable frame 721, are arranged in a circumferential array on the outside of the adjustment shaft 741. The two ends of the connecting rods 742 are hinged to the adjustment shaft 741 and the movable frame 721, respectively. The locking assembly is installed between the mounting frame 71 and the adjustment shaft 741 to fix the two relative to each other. The locking assembly includes a locking rod 743, a fixed mounting block 744, a pull plate 745, a spring 746, and a locking ring 747. The locking ring 747 is fixedly connected to the adjusting shaft 741, the fixed mounting block 744 is fixedly connected to the mounting bracket 71, and the locking rod 743 is slidably connected to the fixed mounting block 744. The pull plate 745 is fixedly mounted on one end of the locking rod 743 away from the adjusting shaft 741, and the other end of the locking rod 743 has a toothed structure that mates with the outer wall of the locking ring 747. A spring 746 is fixedly mounted between the pull plate 745 and the fixed mounting block 744. In this invention, when the modular ring die mechanism 6 rotates, it drives the driven gear 732 to rotate via the active gear ring 731, which in turn drives the pressure roller 722 to rotate synchronously via the universal coupling 734, thus pressing the material. The rotating adjustment shaft 741 can drive the movable frame 721 to move radially along the modular ring die mechanism 6 via the connecting rod 742, thereby adjusting the distance between the pressure roller 722 and the modular ring die mechanism 6. Under the action of the universal coupling 734, the driven gear 732 can always maintain the power transmission effect to the rotating shaft 723. After the adjustment is completed, the adjusting shaft 741 can be locked by the cooperation of the locking rod 743 and the locking ring 747, so that the adjusting shaft 741 and the mounting frame 71 are relatively fixed, keeping the current distance between the pressure roller 722 and the modular ring die mechanism 6 unchanged.

[0026] Please see Figure 6 , Figure 10 , Figure 11 and Figure 12 The modular ring mold mechanism 6 includes an outer ring mold 61, an inner ring mold 62, an outer slot 63, an outer insert block 64, and an inner slot 65. Multiple inner ring molds 62 are arranged in a circular array on the inner side of the outer ring mold 61. An outer insert block 64 is fixedly installed at the outer end of each inner ring mold 62. An outer slot 63 is provided at the outer end of the outer ring mold 61 to engage with the outer insert block 64. An inner insert block 66 is fixedly installed at the inner end of each inner ring mold 62. An inner slot 65 is provided at the inner end of the outer ring mold 61 to engage with the inner insert block 66. A fixing pressure ring 67 is also fixedly installed at the outer end of the outer ring mold 61, and the fixing pressure ring 67 is fixedly connected to the driving gear ring 731. In this invention, the outer ring mold 61 and the inner ring mold 62 are provided with corresponding through holes, and the through hole of the inner ring mold 62 is tapered. When either inner ring mold 62 is damaged, the performance of the ring mold can be restored by replacing only the damaged outer ring mold 61 and the inner ring mold 62. Moreover, the disassembly and assembly steps are simple and convenient to operate, which is beneficial to the work of maintenance personnel.

[0027] Please see Figure 4 and Figure 5 The synchronously adjustable pelletizing mechanism 8 includes a cutter 81, a straight rod 82, a connecting seat 83, and a depth adjustment assembly. Multiple cutters 81, corresponding one-to-one with the movable pelletizing assembly 72, are distributed between the fixed housing 5 and the modular ring die mechanism 6. One end of the straight rod 82 is fixedly connected to the cutter 81, and the other end of the straight rod 82 is slidably connected to the connecting seat 83. The connecting seat 83 is fixedly connected to the outer wall of the fixed housing 5. The depth adjustment assembly is installed on the outside of the fixed housing 5 and is used to control all cutters 81 to move synchronously radially along the modular ring die mechanism 6. The depth adjustment assembly includes an active bevel gear 84, a driven bevel gear 85, a fixed adjustment block 86, a movable adjustment block 87, and an adjustment screw 88. The connecting seat 83 is rotatably connected to the driven bevel gear 85 via a bearing, and the driven bevel gear 85 is threadedly connected to the straight rod 82. The active bevel gear 84 is slidably mounted on the outer wall of the fixed housing 5 along the circumference of the fixed housing 5, and the driven bevel gear 85 is meshed with the active bevel gear 84. The movable adjustment block 87 is rotatably connected to the active bevel gear 84, the fixed adjustment block 86 is rotatably connected to the outer wall of the fixed housing 5, and the adjustment screw 88 is rotatably connected to the fixed adjustment block 86 via a bearing, and the adjustment screw 88 is threadedly connected to the movable adjustment block 87. In this invention, the outer ring die 61, the inner ring die 62, and the pressure roller 722 rotate to cooperate in pelleting. The pelleting operation is achieved by the cutter 81. By rotating the adjusting screw 88, the distance between the fixed adjusting block 86 and the fixed adjusting block 86 can be adjusted, so that the active bevel gear disk 84 slides circumferentially along the fixed housing 5. In turn, the active bevel gear disk 84 drives all the driven bevel gears 85 to rotate. The connecting seat 83 and the driven bevel gears 85 cooperate to control the straight rod 82 to move radially along the fixed housing 5 under the limiting action of the connecting seat 83. This achieves synchronous adjustment of the distance between all cutters 81 and the outer ring die 61, ensuring that the pelleting length of each cutter 81 is consistent, so that the finished feed has uniform specifications.
