[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] like Figures 1-6 As shown, an automated cleaning granulator includes a material bin 1. A feeding hood 11 is fixedly installed at the upper middle part of the material bin 1. Electricly driven granulation rollers 12 are movably connected to the left and right positions of the top of the inner wall of the material bin 1. Roller cleaning components 2 are movably connected to the top of the left and right sides of the material bin 1. A rinsing component 3 is fixedly installed at the left and right positions of the top of the rear side of the material bin 1.

[0030] The roller cleaning assembly 2 includes two movable plates 21. Movable grooves are provided on the top of the left and right sides of the material box 1. The outer sides of the two movable plates 21 are slidably connected to the inner walls of the two movable grooves. Brush plates 22 are fixedly installed on the opposite sides of the two movable plates 21. The two brush plates 22 are located on the side of the outer wall of the two granulation rollers 12 that are far away from each other. A synchronous moving mechanism is fixedly installed on the side of the two movable plates 21 that are far away from each other.

[0031] The rinsing assembly 3 includes two hoses 31. The top of the outer wall of the two hoses 31 is fixedly connected to the inner wall of the upper left and right sides of the material box 1. The lower ends of the two hoses 31 are fixedly installed with connecting pipes 32. The lower ends of the two connecting pipes 32 are fixedly installed with several nozzles 33 arranged in a linear pattern. The rear ends of the two connecting pipes 32 are fixedly installed with adjusting columns 34 that penetrate the rear of the material box 1. The rear outer walls of the two adjusting columns 34 are fixedly connected with relative rotation mechanisms.

[0032] After the work is completed, the roller cleaning assembly 2 cleans the outer surfaces of the two granulation rollers 12 with two brush plates 22. The synchronous movement mechanism drives the two brush plates 22 to move closer together, so that the two brush plates 22 come into contact with the two granulation rollers 12 rotating in opposite directions at the same speed, thereby brushing away stubborn impurities on the surface of the two granulation rollers 12. It is highly practical and beneficial to subsequent processing. The rinsing assembly 3 uses an external water pump to pump the cleaning liquid into the corresponding connecting pipes 32 through two hoses 31. The relative rotation mechanism can simultaneously change the operating angle of the two connecting pipes 32, so that the two connecting pipes 32 rotate relative to each other. This allows the multiple nozzles 33 to not only act on the internal structure of the material box 1, but also rinse the two brush plates 22. It is highly functional and can prevent cross-mixing when processing different types of materials in subsequent processing.

[0033] The front ends of the two granulation rollers 12 are each fixedly installed with a rotating shaft that passes through the inside of the material box 1. The front of the outer wall of the two rotating shafts is fixedly fitted with a rotating gear. A servo motor is fixedly installed on the right side of the front of the material box 1. The output end of the servo motor is fixedly connected to the front end of the right rotating shaft, so that the two granulation rollers 12 can rotate in opposite directions at the same speed.

[0034] like Figure 4 and Figure 5 As shown, the synchronous movement mechanism includes two racks 23. The rear sides of the two racks 23 are slidably connected to the left and right positions of the middle rear side of the material box 1. The two racks 23 are arranged opposite each other. The ends of the two racks 23 that are far apart from each other are fixedly connected to the sides of the two moving plates 21 that are far apart from each other. A drive gear 24 is rotatably connected to the middle rear side of the material box 1. The opposite sides of the two racks 23 mesh with the outer surface of the drive gear 24. A cylinder 25 is fixedly installed at the bottom rear side of the material box 1. The output end of the cylinder 25 is fixedly connected to the lower right side of the left rack 23.

[0035] The output end of the cylinder 25 can drive the left rack 23 to slide. The two racks 23 move relative to each other by meshing with the drive gear 24. When the two granulation rollers 12 need to be cleaned, the two racks 23 can drive the two moving plates 21 to move closer to each other, so that the two brush plates 22 can contact the outer wall of the two granulation rollers 12.

[0036] like Figure 6 As shown, the relative rotation mechanism includes a reverse double threaded rod 35. The left and right ends of the reverse double threaded rod 35 are rotatably connected to the left and right positions of the top rear side of the material box 1. A motor 36 is fixedly installed on the left side of the top rear side of the material box 1. The output end of the motor 36 is fixedly connected to the left end of the reverse double threaded rod 35. The left and right sides of the outer wall of the reverse double threaded rod 35 are threaded with threaded sleeves 37.

[0037] The output end of the motor 36 can drive the reverse double threaded rod 35 to rotate, and the two threaded sleeves 37 move closer to each other / away from each other through threaded connection with the reverse double threaded rod 35.

[0038] like Figure 6 As shown, a guide rail 38 is fixedly installed on the top rear side of the material box 1. The guide rail 38 is located directly in front of the two threaded sleeves 37, and the front sides of the two threaded sleeves 37 are slidably connected to the left and right sides of the inner wall of the guide rail 38.

[0039] The guide rail 38 guides and limits the movement of the two threaded sleeves 37.

[0040] like Figure 6 As shown, racks 39 are fixedly installed on the upper ends of the two threaded sleeves 37, and gears 310 are fixedly sleeved on the rear parts of the outer walls of the two adjusting columns 34. The upper ends of the two racks 39 mesh with the outer surfaces of the two gears 310.

[0041] By moving the two threaded sleeves 37 closer to each other or further apart, the two gears 310 can engage with the corresponding racks 39, thereby driving the two connecting pipes 32 to rotate synchronously in opposite directions.

[0042] like Figure 1 and Figure 2 As shown, both hoses 31 have connectors movably connected to their tops.

[0043] Two connectors are threaded onto two hoses (31) for connecting to external pipes.

[0044] like Figure 3 As shown, symmetrically arranged permeation guide plates 13 are fixedly installed on the left and right sides of the middle of the inner wall of the material box 1. An inclined filter plate 14 is rotatably connected to the bottom of the left side of the inner wall of the material box 1. A discharge chute matching the filter plate 14 is opened at the bottom right side of the material box 1. An installation plate is fixedly installed at the bottom right side of the material box 1. The installation plate is located below the filter plate 14. Springs 15 are fixedly installed at the front and rear of the upper end of the installation plate. The upper ends of the two springs 15 are fixedly connected to the front and rear of the lower right side of the filter plate 14.

[0045] Two permeation guide plates 13 are used to guide the material. When the water is sprayed down, the water will directly pass through the two permeation guide plates 13 and act on the filter plate 14. Secondly, when the material falls, the two springs 15 play a vibration and buffering role, which makes it easier for qualified material to be discharged from the discharge trough.

[0046] like Figure 3 As shown, a through groove is provided at the bottom front side of the material box 1, and a collection box 16 is slidably connected to the bottom of the inner wall of the through groove.

[0047] Non-conforming materials, especially those that are small in size, will be screened out and left in the collection box 16.

[0048] The working principle of this utility model is as follows: When in use, the material continuously falls from the feed hood 11 into the space between two electrically driven granulating rollers 12. The two granulating rollers 12 can shape the material into a specific shape. The material falls and is screened by the filter plate 14. Qualified products are discharged from the discharge chute due to the inclined filter plate 14, while unqualified materials will remain in the collection box 16.

[0049] The surfaces of the two granulation rollers 12 are prone to contamination with impurities due to prolonged contact with materials. The cylinder 25 automatically starts according to the set parameters. At this time, the feed hood 11 no longer enters the material. The output end of the cylinder 25 can drive the left rack 23 to slide. The two racks 23 move relative to each other by meshing with the drive gear 24. When the two granulation rollers 12 need to be cleaned, the two racks 23 can drive the two moving plates 21 to move closer to each other, so that the two brush plates 22 come into contact with the two granulation rollers 12 rotating in opposite directions at the same speed, thereby brushing away the stubborn impurities on the surface of the two granulation rollers 12. This is highly practical and beneficial to subsequent processing.

[0050] Subsequently, the external water pump pumps the cleaning solution from the external water tank into the corresponding connecting pipes 32 through two hoses 31. Simultaneously, the motor 36 starts, and its output drives the reverse double-threaded rod 35 to rotate. Two threaded sleeves 37 move closer / away from each other through their threaded connection to the reverse double-threaded rod 35. Through the movement of the two threaded sleeves 37, two gears 310 can mesh with corresponding racks 39, driving the two connecting pipes 32 to rotate synchronously in opposite directions. This allows the multiple nozzles 33 to not only act on the internal structure of the material bin 1 but also to rinse the two brush plates 22, providing strong functionality and preventing cross-mixing when processing different types of materials. The wastewater collected in the collection box 16 can then be extracted from the channel.

[0051] The roller cleaning assembly 2 and the rinsing assembly 3 enable automated cleaning of the granulator, and are highly practical and have long-term usability.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
