Description

Technical Field

[0001] The present invention relates to the technical field of cat litter solidification and molding, and specifically to a solidification and molding device for a deodorant cat litter particle production line. Background Art

[0002] The core functions of cat litter are water absorption, agglomeration, and deodorization. Its production process generally includes steps such as raw material mixing, molding, solidification, drying, and screening. Among them, the solidification and molding device is a key equipment in the production line, directly affecting the physical properties of the particles, such as strength and porosity, and functional properties, such as water absorption rate and deodorization effect. The solidification and molding devices used in existing cat litter production lines are generally equipment such as flat die pelletizers and ring die pelletizers. The diameter of the finished cat litter particles produced by this type of equipment can be adjusted, the shape is neat and smooth, the pelletizing density is large, and the water absorption effect is good. Therefore, it is widely loved and applied in cat litter production lines.

[0003] However, there are still some problems when the above cat litter solidification and molding equipment is used in the cat litter production line. The raw materials for cat litter pelletizing are generally materials such as corn flour, corn starch, soybean dregs, and pea fiber powder. The small size of the raw material particles results in poor feeding effect during the process of pressing and molding, insufficient feeding amount, and thus the finished product is too soft and prone to falling apart; secondly, the above raw materials are all materials that are easy to adhere to. During the pelletizing process, they are easily pressed and adhered to the upper surface of the die plate, resulting in a decrease in the flatness of the upper surface of the die plate and affecting the production efficiency; finally, since cat litter production requires mixing deodorant components into the raw materials to achieve the deodorization effect of cat litter, the existing solidification and molding devices used in the production line do not have a special structure for mixing deodorant materials. They can only mix the materials with deodorant components in advance before putting in the raw materials. This operation is often unevenly mixed, and it is difficult to ensure that each cat litter particle produced contains deodorant components, resulting in poor deodorization effect of the finished cat litter.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figure 1-2, A curing and forming device for a deodorant cat litter granule production line, including a granulation ring wall 1. An inner wall at the bottom end of the granulation ring wall 1 is fixedly installed with a positioning ring track 101, and a granulation die plate 2 is movably connected through the positioning ring track 101. Granulation die holes 201 are evenly arranged on the outer ring of the granulation die plate 2. An inner wall in the middle of the granulation ring wall 1 is fixedly connected with a central shaft support 3, and a central power shaft 301 is fixedly connected in the middle of the central shaft support 3. The central power shaft 301 is cylindrical, and the central axis of the central power shaft 301 coincides with the central axis of the granulation ring wall 1. A power motor 4 is fixedly installed at the top end of the central power shaft 301. A motor main shaft 401 is movably connected to the bottom of the power motor 4, and a motor gear 402 is fixedly connected through the motor main shaft 401. Four groups of shaft holes are evenly arranged on the side wall below the central power shaft 301. The granulation ring wall 1 is also evenly provided with four groups of shaft holes corresponding to the shaft holes of the central power shaft 301. A roller rotating shaft 5 is movably sleeved at each corresponding shaft hole. An inner end of the roller rotating shaft 5 is fixedly connected with a roller gear 501. The roller gear 501 is vertically meshed with the motor gear 402. When the power motor 4 drives the motor gear 402 to rotate, the four groups of roller rotating shafts 5 are meshed and driven to rotate along the axis of the shaft hole. A roller pressing block 502 is fixedly connected to the outer side of the roller rotating shaft 5. The roller pressing block 502 is located outside the central power shaft 301 on the inner side of the granulation ring wall 1, and the outer wall of the roller pressing block 502 is tangent to the upper surface of the granulation die plate 2. It is ensured that during the rotation of the roller rotating shaft 5, the roller pressing block 502 can mutually extrude the material therein with the upper surface of the granulation die plate 2, and press it into the granulation die holes 201 for forming. A template gear 202 is fixedly connected above the middle of the granulation die plate 2. The template gear 202 is vertically meshed with the roller gear 501, so that while the roller pressing block 502 rotates and extrudes the material, the granulation die plate 2 rotates counterclockwise along the positioning ring track 101, improving the feeding and extrusion effect of the material between the granulation die plate 2 and the roller pressing block 502, and enabling the cat litter to be better extruded and cured into shape.

[0021] Please refer to Figure 3 , A deodorizing chamber sandwich wall 7 is fixedly connected to the bottom of the central shaft support 3. A scraping blade 701 is fixedly installed on one side of the bottom of the deodorizing chamber sandwich wall 7 opposite to the rotation direction of the granulation die plate 2. The lower side of the scraping blade 701 closely adheres to the upper surface of the granulation die plate 2. When the granulation die plate 2 rotates past the fixed scraping blade 701 after being extruded by the roller pressing block 502, the sticky material adhering to the upper surface of the granulation die plate 2 is scraped off. As the scraped sticky material accumulates between the roller pressing block 502 and the deodorizing chamber sandwich wall 7, it is carried out to the extrusion side by the outwardly rotating roller pressing block 502 and re-enters to be pressed into the granulation die holes 201 by the roller pressing block 502 for reuse, avoiding the problem that a large amount of sticky material adheres to the upper surface of the granulation die plate 2, resulting in a reduction in the flatness of the upper surface of the granulation die plate 2 and a decrease in the material pressing efficiency of the roller pressing block 502.

[0022] Please refer to Figure 4-5, an auxiliary material ring wall 6 is fixedly connected to the outer side of the granulation ring wall 1. A cavity is formed in the middle of the central shaft bracket 3, and the cavity communicates downward with the space inside the deodorization cavity sandwich wall 7. A material connection port 102 is provided between the granulation ring wall 1 and the central shaft bracket 3. The material connection port 102 communicates the auxiliary material ring wall 6 with the space inside the deodorization cavity sandwich wall 7, so that the deodorization material in the auxiliary material ring wall 6 can fall into the space inside the deodorization cavity sandwich wall 7. A blanking shaft 702 is fixedly connected to the bottom of the deodorization cavity sandwich wall 7. A blanking vane group 703 is evenly and movably sleeved on the blanking shaft 702. The outer ring of the blanking vane group 703 is in contact with the upper surface of the granulation die plate 2 and can rotate following the movement of the granulation die plate 2. Thus, it is ensured that the rotation speed of the blanking vane group 703 near the outer ring of the granulation die plate 2 is greater than that of the blanking vane group 703 near the inner ring of the granulation die plate 2. Therefore, the feeding amount of the deodorization material in the outer ring of the granulation die plate 2 is more than that in the inner ring of the granulation die plate 2, ensuring that the deodorization material is evenly spread on each circle of the granulation die plate 2, avoiding the phenomenon that the deodorization components are unevenly mixed into the material, and solving the problem that it is difficult to ensure that each cat litter contains deodorization components, ultimately resulting in poor deodorization effect. An auxiliary material groove ring gear 601 is movably sleeved on the inner wall of the auxiliary material ring wall 6. Auxiliary material paddles 602 are evenly fixedly connected to the bottom of the auxiliary material groove ring gear 601. The auxiliary material groove ring gear 601 is driven to rotate in the auxiliary material ring wall 6 by a power device, and the auxiliary material paddles 602 are driven to rotate to push the deodorization material in the auxiliary material ring wall 6 into the device through the material connection port 102, avoiding the problem that a material-free cavity is formed in the deodorization cavity sandwich wall 7, resulting in discontinuous mixing of the deodorization material.

[0023] The working principle of the usage method of the present invention is as follows: In use, the cat litter material is continuously fed from above the device into the granulation ring wall 1, and the deodorant component material is fed into the auxiliary material ring wall 6. After the power motor 4 is started, the motor gear 402 rotates to drive the four groups of roller shafts 5 to rotate along the axis of the shaft holes. During the rotation of the roller shafts 5, the roller pressing blocks 502 can squeeze the material between them with the upper surface of the granulation die plate 2, so that the material is pressed into the granulation die holes 201 to form. At the same time, the template gear 202 is driven, so that the granulation die plate 2 rotates counterclockwise along the positioning ring track 101, improving the extrusion effect of the material between the granulation die plate 2 and the roller pressing blocks 502, making the cat litter better extruded and solidified into shape. At the same time, when the rotating granulation die plate 2 passes through the scraping blade 701, the sticky material adhering to the upper surface of the granulation die plate 2 is scraped off, and is taken out to the extrusion side by the roller pressing blocks 502 rotating outward, and is re-pressed into the granulation die holes 201 by the roller pressing blocks 502 for reuse. At the same time, as the auxiliary material dial 602 rotates, it pushes the deodorant material in the auxiliary material ring wall 6 to enter the deodorant cavity sandwich wall 7 through the auxiliary material communication port 102, and the blanking rotating blade group 703 with an increasing rotation speed from inside to outside evenly spreads the deodorant material on the granulation die plate 2 scraped by the scraping blade 701, so that there is a deodorant material spreading operation before each extrusion of the cat litter material to form, ensuring that each cat litter contains deodorant components, making the deodorizing effect of the produced cat litter better.
