Description

Technical Field

[0001] The invention relates to the technical field of cat litter processing, and more particularly to a plant cat litter processing and molding device. Background Art

[0002] Cat litter is mainly used by cats to bury feces and urine. It has good water absorption. Cat litter usually comes in granular, long cylindrical shapes, etc. Plant cat litter is a kind of cat litter made of natural plant materials. It has the characteristics of environmental protection, biodegradability and high efficiency moisture absorption. In the production process of plant cat litter, corn starch, soybean fiber and other natural plant materials are usually mixed. After mixing, it is made into long strips or flat shapes through pressing equipment. Finally, the pressed cat litter is crushed to make it granular for storage.

[0003] Most of the existing plant cat litters are mainly pressed and formed by double rollers during the molding process, and the large pieces of plant cat litter after molding are crushed by a crusher to obtain granular plant cat litter. However, the particle sizes of the plant cat litter made in this way are inconsistent. Particles of different sizes will affect the odor control effect of the cat litter. Large particles may not be able to absorb liquid and odor evenly, resulting in difficulty in controlling the odor in the cat litter box. At the same time, if the cat litter contains fine particles, more dust will be generated during use, which will affect the respiratory health of cats and breeders. In order to ensure the uniform particle size of plant cat litter, the prior art uses a vibrating screening device to screen the particles into different sizes after production is completed. The particles that do not meet the requirements can be separated by screening with a vibrating screen to ensure that the particle size of the final product is uniform. However, the finished product is screened after the production is completed, which adds the final production time of the product, greatly reducing the production efficiency of the plant cat litter and increasing the defective rate of the plant cat litter in the production process.

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0032] refer to Figure 1 , Figure 2 , Figure 3 A plant cat litter processing and molding equipment is used for the processing and production of granular cat litter, including an equipment body 1, a feed hopper 11 is installed at the top of one side of the equipment body 1, and a discharge port 12 is opened at the bottom of the equipment body 1 on the same side, a transmission box 14 is arranged on one side of the feed hopper 11, and a reduction box 13 is arranged on one side of the transmission box 14, a movement cavity 15 is opened in the equipment body 1, and a driving mechanism 2 is arranged in the movement cavity 15, and the driving mechanism 2 is connected to the reduction box 13; a pressing roller 3 is arranged below the feed hopper 11, and the pressing roller 3 is symmetrically arranged below the feed hopper 11, the The pressing roller 3 is connected to the transmission box 14, and the transmission box 14 drives the pressing roller 3 to move synchronously through the rotation of the driving mechanism 2. A plurality of pressing grooves 31 are arranged in an array on the outer circumferential surface of the pressing roller 3, and the pressing grooves 31 are used to press the cat litter raw materials into regular shapes; a control mechanism 4 is arranged on one side of the pressing roller 3, and the control mechanism 4 realizes the uniformity of the molding length of the plant cat litter through the rotation of the pressing roller 3, and a crushing mechanism 5 is arranged below the control mechanism 4, and the crushing mechanism 5 moves synchronously with the driving mechanism 2, and the movement of the crushing mechanism 5 will make the plant cat litter passing through the pressing roller 3 into cat litter particles.

[0033] During the working process, the operator first adds the mixed cat litter raw materials into the feed hopper 11 arranged above the equipment body 1. At this time, the operator starts the driving mechanism 2, and the driving mechanism drives the pressing roller 3 to rotate through the transmission box 14. When the pressing roller 3 rotates, the pressing roller 3 drives the control mechanism 4 to move synchronously. At this time, the pressing ring 43 in the control mechanism 4 is evenly spaced. When the plant cat litter raw materials pass through the pressing roller 3, due to the pressing groove 31 on the surface of the pressing roller 3, the plant cat litter raw materials passing through the pressing roller 3 will form a strip-shaped plant cat litter with an indentation. The pressing ring 43 coaxially arranged on the surface of the pressing roller 3 is coaxially arranged with the pressing roller 3 during the rotation of the pressing roller 3. Due to the pressing The ring 43 will unfold as the pressing roller 3 rotates. At this time, when the pressing roller 3 rotates to form the cat litter raw material, the strip-shaped plant cat litter with indentations will have multiple new indentations that are perpendicular to the previous indentations. The plant cat litter with indentations will fall downward due to its own gravity. At this time, due to the continuous movement of the driving mechanism 2, the driving mechanism 2 drives the crushing mechanism 5 to crush the strip-shaped plant cat litter with indentations. When the plant cat litter is crushed, the formed plant cat litter will be crushed along the indentation position, so that the particle size of the plant cat litter in the final product remains consistent, thereby improving the quality of the final product and avoiding the situation where the plant cat litter particles are of different sizes, resulting in a decrease in the moisture absorption efficiency of the plant cat litter.

[0034] The driving mechanism 2 includes a driving motor 21, a large pulley 22, a small pulley 24, a driving shaft 25, a driven shaft 26 and a transmission gear 27. The driving motor 21 is arranged on one side of the reduction box 13, and the large pulley 22 is connected to the output end of the reduction box 13. A small pulley 24 is arranged below the large pulley 22, and the large pulley 22 and the small pulley 24 are in the same plane. The large pulley 22 and the small pulley 24 are connected by a belt 23. A driving shaft 25 is arranged at the center of the small pulley 24, and a driven shaft 26 is arranged on one side of the driving shaft 25. The driving shaft 25 and the driven shaft 26 are provided with the same transmission gear 27, and the transmission gears 27 on the driving shaft 25 and the driven shaft 26 are meshed with each other. The driving shaft 25 and the driven shaft 26 are connected to a crushing mechanism 5 at one end away from the small pulley 24.

[0035] During the working process, when the driving motor 21 rotates, through the movement of the driving motor 21, since the driving motor 21 is connected to the reduction box 13, the output end of the reduction box 13 is connected to the central axis of the large pulley 22, at this time, the large pulley 22 can be driven by the driving motor 21 to rotate, and the rotation of the large pulley 22 drives the small pulley 24 to rotate through the belt 23. The pulley transmission can improve the stability of the overall movement of the equipment. During the rotation of the small pulley 24, the small pulley 24 drives the coaxially mounted active shaft 25 to rotate. When the active shaft 25 rotates, due to the mutually meshing transmission gears 27 set on the active shaft 25 and the driven shaft 26, the active shaft 25 can drive the driven shaft 26 to rotate. The active shaft 25 and the driven shaft 26 are connected to a crushing mechanism 5 away from the pulley end. At this time, the plant cat litter that falls due to its own gravity is converted into a finished cat litter with uniform particle size by the crushing mechanism 5 driven by the active shaft 25.

[0036] like Figure 4 , Figure 5 As shown, the feed hopper 11 is a frustum structure with a large upper end and a small lower end, and the small end of the feed hopper 11 is connected to the equipment body 1, and the equipment body 1 is inclinedly provided with a discharge port 12 on one side close to the feed hopper 11, and a guide plate is obliquely connected to one side of the discharge port 12. Through such a setting, the raw materials of the plant cat litter can flow downward evenly and smoothly in the feed hopper 11, and the blockage of the raw materials of the plant cat litter can be avoided. This can ensure that the raw materials of the plant cat litter always maintain a constant speed of downward flow. The inclined discharge port 12 and the guide plate provided at the discharge port 12 can guide the finished plant cat litter to slide downward along the surface of the guide plate, thereby ensuring the flow stability of the finished plant cat litter during the production and processing process.

[0037] The control mechanism 4 includes a guide block 41, a control ring 42 and a pressure ring 43. The guide block 41 is arranged below the feed hopper 11, and the guide block 41 is an inverted cone structure. The large end of the guide block 41 fits with the small end of the feed hopper 11. A pressure roller 3 is arranged below the guide block 41, and a control ring 42 is arranged between the guide block 41 and the pressure roller 3. An arc-shaped inclined groove 411 is provided at the fitting position of the guide block 41 and the control ring 42. The arc-shaped inclined groove 411 is arranged on the surface of the guide block 41, and there are multiple arc-shaped inclined grooves 411. A limiting column 421 is arranged on the side of the control ring 42 that contacts the guide block 41, and the limiting column 421 is arranged in the arc-shaped inclined groove 411. A limiting groove 422 is provided on the side of the control ring 42 away from the guide block 41, and a pressure ring 43 is arranged in the limiting groove 422, and the pressure ring 43 is arranged on the pressure roller 3.

[0038] During operation, when the pressing roller 3 rotates, the pressing roller 3 drives the limiting column 421 on the control ring 42 to slide along one end of the arc-shaped inclined groove 411 set on the guide block 41 to the other end of the arc-shaped inclined groove 411. Since there are multiple control rings 42, and the control rings 42 and the arc-shaped inclined groove 411 are equidistantly arranged, during the rotation of the pressing roller 3, multiple control rings 42 are equidistantly dispersed above the pressing roller 3, and a pressing ring 43 is arranged in the limiting groove 422 on the side of the control ring 42 close to the pressing roller 3. When the control rings 42 are equidistantly dispersed, the control rings 42 The ring 42 drives the pressing ring 43 to be evenly and equidistantly arranged on the surface of the pressing roller 3. At this time, when the plant cat litter raw material passes through the pressing roller 3, when the pressing roller 3 rotates, the pressing groove 31 and the pressing ring 43 cooperate to form the plant cat litter. In the process, an indentation will be formed on the surface of the strip-shaped plant cat litter after the formation. At the same time, the inverted cone structure of the guide block 41 can make the plant cat litter raw material fall evenly to the pressing roller 3. At this time, the formed plant cat litter can be more uniform and saturated, thereby improving the quality of the final cat litter product.

[0039] The pressing ring 43 is coaxially arranged with the pressing roller 3, and the inner circumferential surface of the pressing ring 43 is provided with a protrusion 441 that cooperates with the pressing groove 31. The pressing ring 43 is arranged in a linear array on the circumferential surface of the pressing roller 3. Through such a configuration, when the pressing ring 43 is expanded and contracted, the protrusion 441 on the inner circumferential surface of the pressing ring 43 will clean the cat litter raw materials remaining in the pressing groove 31, and at this time, it can be ensured that the pressing roller 3 can press and form relatively full plant cat litter, thereby avoiding the appearance of defective plant cat litter.

[0040] A magnetic part is arranged between the pressing ring 43 and the control ring 42. When the pressing roller 3 rotates to a certain speed, the driving force of the pressing roller 3 to drive the pressing ring 43 to move synchronously is greater than the adsorption force of the magnetic part between the pressing ring 43 and the control ring 42. Through such an arrangement, before the pressing work starts, the pressing roller 3 passes through the magnetic part between the pressing ring 43 and the control ring 42, and the pressing ring 43 can first be evenly spread on the surface of the pressing roller 3. When the pressing roller 3 continues to rotate, the pressing roller 3 can drive the pressing ring 43 to rotate, thereby producing an indentation on the formed plant cat litter. After the pressing work is completed, the rotation speed of the pressing roller 3 is reduced. At this time, the rotation of the pressing roller 3 can drive the control ring 42 to rotate, so that the limit column 421 on the control ring 42 moves on the arc-shaped inclined groove 411.

[0041] like Figure 6 , Figure 7 , Figure 8As shown, the press roller 3 is symmetrically arranged below the guide block 41, and limiting blocks 44 are arranged on both sides of the press groove 31. The contact portion between the limiting blocks 44 and the press roller 3 is an arc structure, and the limiting blocks 44 are in contact with the press roller 3. Through such an arrangement, when the cat litter raw material is pressed by the press roller 3, the limiting blocks 44 can prevent the cat litter raw material from leaking, thereby avoiding waste of cat litter raw material. At the same time, the contact portion between the limiting blocks 44 and the press roller 3 is provided with a plurality of groups of protrusions 441, the material of the protrusions 441 is a hard material, and the protrusions 441 are in contact with the press groove 31. When the press roller 3 rotates, the protrusions 441 can clean up the cat litter raw material remaining in the press groove 31, thereby avoiding the cat litter raw material from being blocked in the press groove 31 for a long time, causing the press roller 3 to press out cat litter particles that do not meet the standards.

[0042] The crushing mechanism 5 includes a rotating roller 51, a fixed vertical plate 52 and a crushing column 53. The rotating roller 51 is provided with two groups, and the rotating roller 51 is respectively connected to one end of the driving rotating shaft 25 and the driven rotating shaft 26. A plurality of fixed vertical plates 52 are arranged in an array on the outer circumferential surface of the rotating roller 51, and a plurality of groups of crushing columns 53 are arranged on the fixed vertical plates 52. The crushing columns 53 are symmetrically arranged on both sides of the fixed vertical plates 52. The diameter of the crushing columns 53 is consistent with the width of the material pressing trough 31, and the crushing columns 53 are made of soft material.

[0043] During operation, when the strip-shaped cat litter with an indentation falls onto the rotating roller 51 due to its own gravity, the rotating roller 51 rotates to drive the crushing columns 53 on the fixed vertical plate 52 to squeeze the strip-shaped cat litter. At this time, since the surface of the formed cat litter has an indentation, when the crushing columns 53 continue to apply extrusion pressure to the formed cat litter, the strip-shaped cat litter will break along the indentation, thereby breaking into cat litter particles. Since the indentation is evenly distributed on the surface of the formed cat litter, when the crushing columns 53 apply extrusion pressure to the strip-shaped cat litter, the strip-shaped cat litter will break along the indentation, thereby forming cat litter particles with uniform particle size, thereby improving the quality of the plant cat litter.

The protection scope of the present invention is defined by the claims.
