[0001] This utility model relates to the field of grinding equipment technology, specifically to a grinding equipment for processing kale. Background Technology

[0002] In the food and health product processing industry, kale is increasingly favored by consumers due to its rich content of vitamins, minerals and dietary fiber. Processing kale into powder helps to better preserve its nutrients and makes it convenient to use in the production of various products, such as nutritional supplements and functional foods.

[0003] If the raw materials in the existing grinding equipment are not sufficiently crushed in the early stage and are directly put into the gap of the grinding disc, it will increase the workload of the grinding disc, reduce the grinding efficiency, and shorten the service life of the grinding disc. In addition, the existing grinding equipment lacks an effective screening and secondary processing mechanism for the crushed raw materials, and cannot promptly re-crush the incompletely crushed raw materials, resulting in unqualified large particles being mixed into the finished product, which seriously affects product quality and production efficiency. Utility Model Content

[0004] Therefore, this utility model provides a grinding equipment for kale processing. By coordinating the crushing component and the grinding component, it solves the problem that if raw materials are not sufficiently pre-crushed and directly enter the gap of the grinding disc, it will increase the workload of the grinding disc and affect product quality and production efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grinding equipment for processing kale, comprising a grinding equipment assembly, a crushing component on one side of the grinding equipment assembly, a grinding component inside the grinding equipment assembly, a grinding tank, a raw material inlet on one side of the grinding tank, a powder outlet fixedly located at the bottom of the grinding tank, a sieve disc and an upper grinding disc fixedly located inside the grinding tank, a crushing box including a crushing chamber fixedly connected to the grinding tank, a raw material outlet on one side of the crushing box communicating with the raw material inlet, a raw material inlet fixedly located at the top of the crushing box, two raw material collection blocks fixedly located inside the crushing box, two crushing units inside the crushing box, each crushing unit including a rotating shaft, and a crushing roller and a gear fixedly sleeved on the outside of the rotating shaft.

[0006] Preferably, the grinding assembly includes a second motor, which is fixedly mounted on the top of the grinding tank. A drive shaft is fixedly connected to the output end of the second motor. A secondary crushing blade and a lower grinding disc are fixedly mounted on the outside of the drive shaft, and an auxiliary fixing frame is mounted on the bottom of the drive shaft.

[0007] Preferably, the drive shaft passes through the top of the grinding tank and is connected to the top of the grinding tank via a bearing; the drive shaft passes through the sieve disc and is connected to the sieve disc via a bearing; the bottom of the drive shaft passes through the auxiliary fixing frame and is connected to the auxiliary fixing frame via a bearing; and the auxiliary fixing frame is fixedly connected to the inner wall of the grinding equipment assembly.

[0008] Preferably, a motor is fixedly installed on one side of the crushing box, and the output end of the motor is fixedly connected to one end of one of the rotating shafts.

[0009] Preferably, the rotating shaft passes through both sides of the crushing chamber and is connected to both sides of the crushing chamber via bearings.

[0018] See attached document Figure 1 -Appendix Figure 4This utility model provides a grinding equipment for processing kale, including a grinding equipment component 1, a crushing component 3 on one side of the grinding equipment component 1, a grinding component 4 inside the grinding equipment component 1, a grinding tank 11, a grinding raw material inlet 12 on one side of the grinding tank 11, a powder outlet 13 fixedly provided at the bottom of the grinding tank 11, a sieve plate 14 and an upper grinding plate 15 fixedly provided inside the grinding tank 11, a crushing box 31 including a crushing box 31, a crushing box 31 fixedly connected to the grinding tank 11, a crushing raw material outlet 32 on one side of the crushing box 31, the crushing raw material outlet 32 being connected to the grinding raw material inlet 12, a raw material inlet 33 fixedly provided at the top of the crushing box 31, two raw material collection blocks 34 fixedly provided inside the crushing box 31, and two crushing units inside the crushing box 31, each crushing unit including a rotating shaft 36, with a crushing roller 37 and a gear 38 fixedly sleeved on the outside of the rotating shaft 36; In this implementation scheme, in order to achieve the purpose of fully crushing the kale raw material before grinding, the kale raw material is fed into the crushing box 31 through the raw material inlet 33. Two relatively rotating crushing rollers 37 use strong extrusion and shearing forces to perform preliminary crushing of the kale raw material, breaking larger pieces of raw material into smaller particles. The pre-crushed kale raw material enters the screen plate 14 in the grinding tank 11 through the crushing raw material outlet 32 and the grinding raw material inlet 12. The unqualified raw material that fails to pass through the filter holes on the screen plate 14 will be crushed again by the high-speed rotating secondary crushing blades 43. The secondary crushing blades 43 use sharp blades and the strong impact force generated by high-speed rotation to crush these larger particles of raw material a second time. With the close cooperation of the screen plate 14 and the secondary crushing blades 43, the incompletely crushed kale raw material is intercepted and crushed again, ensuring that all raw materials entering the grinding stage can meet the specified particle size requirements. To achieve the purpose of grinding the crushed kale raw material, this device adopts the following technical solution: The grinding component 4 includes a second motor 41, which is fixedly mounted on the top of the grinding tank 11. A drive shaft 42 is fixedly connected to the output end of the second motor 41. A secondary grinding blade 43 and a lower grinding disc 44 are fixedly sleeved on the outside of the drive shaft 42. An auxiliary fixing frame 45 is sleeved on the bottom of the drive shaft 42. The drive shaft 42 passes through the top of the grinding tank 11 and is connected to the top of the grinding tank 11 through a bearing. The drive shaft 42 passes through the sieve disc 14 and is connected to the sieve disc 14 through a bearing. The bottom of the drive shaft 42 passes through the auxiliary fixing frame 45 and is connected to the auxiliary fixing frame 45 through a bearing. The auxiliary fixing frame 45 is fixedly connected to the inner wall of the grinding equipment component 1. The kale raw material after preliminary crushing... The material enters the sieve plate 14 inside the grinding tank 11 through the crushing raw material outlet 32 and the grinding raw material inlet 12. The filter holes distributed on the sieve plate 14 are like a precise screening checkpoint. The crushed qualified raw material that meets the particle size requirements can pass through the filter holes smoothly and fall onto the upper grinding plate 15 below. Due to the specific inclined structure design of the upper grinding plate 15, the raw material falling on it will slowly slide into the gap between the upper grinding plate 15 and the lower grinding plate 44. In this gap area, the rotating lower grinding plate 44 and the stationary upper grinding plate 15 cooperate with each other. Using the grinding action between the two, the kale raw material that has entered the gap is finely ground and finally ground into powder that meets the production requirements. The finished product after grinding is discharged and collected through the powder outlet 13. To achieve the purpose of crushing kale raw materials by the relative rotation of the two crushing rollers 37, the device adopts the following technical solution: a motor 35 is fixedly installed on one side of the crushing box 31, and the output end of the motor 35 is fixedly connected to one end of one of the rotating shafts 36. The rotating shaft 36 passes through the two side walls of the crushing box 31 and is connected to the two side walls of the crushing box 31 through bearings. Two gears 38 are located outside the crushing box 31 and mesh with each other. The kale raw materials are fed into the crushing box 31 through the raw material inlet 33. The two raw material gathering blocks 34 set in the crushing box 31 play a key role. They can cleverly gather and guide the raw materials entering the box, so that the raw materials fall accurately and centrally into the working area of the two crushing rollers 37. The two relative rotating crushing rollers 37 use strong extrusion and shearing forces to perform preliminary crushing of the kale raw materials, breaking larger pieces of raw materials into smaller particles. In order to support the device, the device adopts the following technical solution: a support frame 2 is fixedly connected to the outside of the grinding tank 11. The support frame 2 supports the grinding tank 11 and makes the area below the powder outlet 13 empty, which facilitates the subsequent receiving or transfer of the finished product after grinding.

[0019] The usage process of this utility model is as follows: When using this utility model, connect an external power source and first start motor one 35 and motor two 41. Motor one 35 starts running, and its output end drives the connected rotating shaft 36 to rotate. Through the transmission and cooperation of two meshing gears 38, the two crushing rollers 37 rotate at high speed in a relative rotation manner, providing strong power for the initial crushing of raw materials. At the same time, motor two 41 rotates, driving the transmission shaft 42 to rotate synchronously. The transmission shaft 42 drives the secondary crushing blade 43 and the lower grinding disc 44, which are sleeved on its outside, to start working. The rotation of the lower grinding disc 44 and the high-speed rotation of the secondary crushing blade 43 provide power for the subsequent crushing. The process involves preparing the kale for grinding and secondary crushing. Then, the kale raw material is fed into the crushing chamber 31 through the raw material inlet 33. Two raw material concentrators 34 within the crushing chamber 31 play a crucial role, skillfully gathering and guiding the incoming raw material, ensuring it falls precisely and centrally into the working area of the two crushing rollers 37. The two opposing rotating crushing rollers 37, with their powerful extrusion and shearing forces, perform preliminary crushing of the kale raw material, breaking larger pieces into smaller particles. The pre-crushed kale raw material then passes through the crushing raw material outlet 32 and the grinding raw material inlet 1. 2. The raw material enters the sieve plate 14 inside the grinding tank 11. The filter holes distributed on the sieve plate 14 act as a precise screening gate. The qualified raw material that meets the particle size requirements can pass smoothly through the filter holes and fall onto the upper grinding plate 15 below. Due to the specific inclined structure design of the upper grinding plate 15, the raw material falling on it will slowly slide down the slope into the gap between the upper grinding plate 15 and the lower grinding plate 44. In this gap area, the rotating lower grinding plate 44 and the stationary upper grinding plate 15 cooperate with each other, using the grinding action between the two to finely grind the kale raw material that has entered the gap, and finally grind the raw material into a powder that meets the production requirements. The finished product after grinding is discharged and collected through the powder outlet 13; while the unqualified raw materials that fail to pass through the filter holes on the sieve plate 14 are further ground by the high-speed rotating secondary crushing blade 43. The secondary crushing blade 43, with its sharp blade and the powerful impact force generated by high-speed rotation, performs secondary crushing on these larger particles. With the close cooperation between the sieve plate 14 and the secondary crushing blade 43, the incompletely ground kale raw materials are intercepted and ground again, ensuring that all raw materials entering the grinding stage can meet the specified particle size requirements. This effectively avoids unqualified large particles from being mixed into the finished product, greatly improving the quality and production efficiency of kale grinding.

[0020] The above are merely preferred embodiments of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
