Description

Technical Field

[0001] This utility model belongs to the field of cat litter manufacturing, specifically a cat litter pelletizer that facilitates adjustment of pellet size. Background Technology

[0002] Currently, cat litter is an object used by owners to bury feces and urine in their cats. It has good absorbency and is usually used in conjunction with a litter box. An appropriate amount of cat litter is poured into the litter box, and a trained cat will walk into the litter box and defecate on it when it needs to relieve itself. Cat litter is usually in the shape of a long cylindrical strip and is made by a cat litter pellet mill.

[0003] A search revealed that CN220126145U discloses a cat litter pelletizer with adjustable particle size. It uses a fixed baffle, a fixed block, a connecting pipe, an adjusting plate, and an extension plate. The adjusting plate aligns corresponding holes with the holes on the fixed block to produce cat litter of different coarse sizes, allowing for the production of cat litter of specific sizes as needed. However, it does not address how to clean the residual material inside the outer shell after production. After production, this residual material will solidify inside the outer shell, clogging the internal structure and the holes in the adjusting plate. Utility Model Content

[0004] The technical problem to be solved by this utility model is the problem of blockage caused by residual raw materials inside a cat litter pellet mill with adjustable particle size.

[0005] To solve the above-mentioned technical problems, the inventors of this utility model, through practice and summarization, have derived the technical solution of this utility model, which adopts the following technical solution:

[0035] Example 1

[0036] like Figure 1 and Figure 2 As shown, a cat litter pelletizer with easily adjustable particle size includes:

[0037] Cat litter dispenser 10, the bottom of which is open;

[0038] The extrusion component 20 is independently disposed above the cat litter raw material cylinder 10. A pressure component 21 is installed on the upper surface of the extrusion component 20, and a cleaning component 22 is provided on the extrusion component 20.

[0039] The support frame 30 has a support platform 31 mounted on its top. An adjustment slot 32 is provided horizontally in the middle of the support platform 31. A stepper motor 33 is mounted on the support platform 31, and a transmission gear is mounted at the end of the stepper motor 33.

[0040] The forming plate 40 is slidably fitted at the adjustment slot 32 of the support platform 31. Various hole types 42 are evenly distributed on the forming plate 40 along the direction of movement. A rack 41 is installed on the forming plate 40, and the rack 41 meshes with the transmission gear.

[0041] In practice, raw materials are fed into the cat litter raw material cylinder 10 and the top is leveled. The extruder 20 descends via the pressurizing component 21. An opening and closing valve is installed on the top of the extruder 20. The valve is controlled to allow gas to escape during the initial stage. When the extruder 20 descends and contacts the internal raw materials, the valve closes, and the pressurizing component 21 drives the extruder 20 downwards. The raw materials are formed through the corresponding perforated area 42 to obtain cat litter of the corresponding cross-sectional size. The position of the perforated area 42 is adjusted by the control system, which controls the stepper motor 33 to drive the transmission gear via the rack 41 to slide the forming plate 40 within the adjusting slot 32. After production is complete, the cleaning component 22 cleans the corresponding perforated area 42, thus cleaning the inside of the holes.

[0042] Meanwhile, a telescopic cylinder can be installed in the cat litter material cylinder 10. The piston rod end of the telescopic cylinder is connected to an installation platform, which is used to install the pressure component 21 (preferably a cylinder).

[0043] Example 2

[0044] In the cat litter pelletizer of Embodiment 1, as Figure 2 , 3 As shown in Figure 4, the extruder 20 has mounting holes that are evenly distributed and adapted to the positions of the hole-shaped area 42;

[0045] The cleaning component 22 includes a hollow cleaning column 221 installed in the mounting hole. The top of the hollow cleaning column 221 is connected to an external electromagnetic reversing valve and an air pump 222 via an air pipe. A cleaning rod 223 with a cleaning hole area 42 is slidably installed inside the hollow cleaning column 221.

[0046] The cleaning rod 223 consists of multiple concentrically arranged cleaning bodies. The end of the cleaning body located in the center has a closed structure. The air pump 222 is controlled by an electromagnetic reversing valve to inflate the cleaning hollow column 221 to extend the cleaning body outward, thereby realizing the cleaning operation inside the hole. When retracted, the spring inside the cleaning body will automatically drive the inner cleaning body to return to its original position. At the same time, the electromagnetic reversing valve controls the internal of the cleaning hollow column 221 to connect directly to the outside for deflating.

[0047] Example 3

[0048] In the cat litter pelletizer of Embodiment 1, as Figure 2 , 5 As shown, a conveyor belt assembly 50 is independently installed below the support platform 31. The conveyor belt assembly 50 is provided with multiple longitudinally arranged strip grooves 51. The formed cat litter is in the shape of long strips and falls into the strip grooves 51 for continuous conveying, avoiding deformation or clumping caused by direct cutting and falling from the bottom of the forming perforated plate 40.

[0049] A leveling plate 52 is installed at the bottom of the support platform 31, such as... Figure 5 As shown, the bottom of the tidying plate 52 is provided with multiple tidying strips 53. The tidying strips 53 can automatically tidy up the litter strips passing through their own positions into the strip grooves 51.

[0050] A cutting assembly 60 is installed at the bottom of the support platform 31. The cutting assembly 60 includes a linear module 61 installed at the bottom of the support platform 31. A lifting component 62 is installed on the slide of the linear module 61, and a blade 63 is installed at the end of the lifting component 62. When cutting, it is necessary to ensure that the moving speed of the linear module 61 is equal to the conveying speed of the conveyor belt assembly 50. This will prevent the cat litter particles from having irregular ends due to speed differences.

[0051] One form is: such as Figure 7 As shown, a cutting groove 511 is provided on the strip groove 51. During cutting, the cutting groove 511 and the blade 63 are in the same position to achieve adaptation and complete the cutting operation.

[0052] Another form is: such as Figure 8 As shown, the blade 63 is provided with a number of cutting sections 66 that are adapted to the strip groove 51. The cutting sections 66 can correspond to the position of the strip groove 51 and complete the cutting operation.

[0053] Example 4

[0054] In the cat litter pelletizer of Embodiment 1, as Figure 2 , 6 As shown, the bottom of the support platform 31 is connected to a drying chamber 70 via a hanger 71. An electric heating wire 72 and a blower 73 are installed on the top of the inner side of the drying chamber 70. A certain gap is reserved between the bottom of the drying chamber 70 and the conveyor belt assembly 50. Airflow is supplied to the bottom of the drying chamber 70 by the blower 73 and heated by the electric heating wire 72, thereby completing the drying process of the cat litter particles.
