Description

Technical Field

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

[0002] Crushing equipment is a type of mechanical equipment used to grind various materials into fine or ultrafine powders. It is widely used in food, medicine, chemical, building materials, mining, agriculture, and many other fields. Crushing equipment typically consists of a drive unit (motor, reducer), a crushing chamber, grinding media (such as grinding rollers, grinding discs, hammers, steel balls, etc.), a grading system (such as cyclone separators, screens, air classifiers), and a dust collection device. After the material enters the crushing chamber, it is repeatedly impacted, rubbed, and sheared under the action of high-speed rotating grinding media or airflow, gradually refining it to the target particle size. Then, the qualified fine powder is separated by the grading system, while the coarse particles are returned for further crushing. Based on differences in crushing principles and structures, crushing equipment can be classified into mechanical (such as Raymond mills, ball mills, air jet mills, and ultrafine pulverizers), air jet (such as fluidized bed air jet mills), impact (such as impact pulverizers), and shear (such as colloid mills).

[0003] For example, the invention patent with application number CN201810890560.7, entitled "Pre-crushed Rotary Pneumatic Feed Dispersing and Grinding Equipment", involves raw materials sliding into the equipment through an inclined plate frame, which then stay on the conveyor plate. The push rod, driven by the gas, causes the telescopic rod in front to press forward and push the fixed frame in front, causing the striking plate to beat the raw materials up and down, breaking large pieces of raw materials into smaller pieces before further grinding. However, this device requires manual feeding, resulting in poor grinding efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a pulverizing device for processing herbal foods, which aims to improve the problem that conventional pulverizing equipment requires manual feeding, resulting in poor pulverizing efficiency.

[0010] The feed inlet is equipped with an electrically controlled feed gate;

[0011] The drive module includes a drive motor and a current sensor;

[0012] The drive motor drives the hammer assembly and the discharge assembly to rotate. The current sensor is electrically connected to the signal input terminal of the controller to transmit the current value of the drive motor to the controller. The output terminal of the controller is electrically connected to the electrically controlled material gate to control the opening degree of the feed inlet.

[0013] Furthermore, the drive module also includes a voltage regulator, which is electrically connected to the drive motor to provide a stable voltage to the drive motor.

[0014] Furthermore, a connecting pipe is provided on the discharge port, and the hopper is connected to the connecting pipe to form a feeding channel.

[0015] The electrically controlled material gate includes an electric push rod and a material gate. The electric push rod is fixed to the outside of the connecting pipe and is electrically connected to the controller.

[0016] The material gate includes a drive section and an opening / closing section. The drive section is located above the connecting pipe and is fixedly connected to the drive end of the electric actuator. The opening / closing section extends downward to the space between the hopper and the connecting pipe.

[0017] Furthermore, a guide block and a guide rod are fixed to the outside of the connecting pipe. The guide rod is inserted into the guide block and fixedly connected to the drive section.

[0018] Furthermore, the drive module also includes a bearing housing and a drive spindle. The bearing housing is fixed at both ends of the pulverizer body, and the drive spindle passes through the pulverizer body and is rotatably connected to the bearing housing. A driven wheel is fixed on the drive spindle, and a drive wheel is provided at the drive end of the drive motor. A transmission component is connected between the drive wheel and the driven wheel.

[0019] The hammerhead assembly is mounted on the drive spindle;

[0020] The discharge assembly includes multiple fan blades, which are fixed on the drive spindle.

[0021] Furthermore, an outwardly extending mounting portion is fixed on the drive spindle. The mounting portion is located inside the powder grinding chamber and is fixed with a mounting rod. One end of the hammer assembly is rotatably connected to the mounting rod.

[0022] Furthermore, the pulverizer body includes an upper cover and a lower cover, which together form a pulverizing chamber and a discharge chamber.

[0023] The upper and lower covers are respectively fixed with an upper gear ring and a lower gear ring inside, which are located inside the powder grinding chamber and enclose the hammer head assembly.

[0024] Furthermore, it also includes a cooling module.

[0025] The drive spindle has a cooling channel inside; a cooling chamber is formed between the lower cover and the lower gear ring; the cooling module is connected to the cooling pipe and the cooling chamber, and delivers coolant to the cooling pipe and the cooling chamber.

[0045] Example

[0046] Please refer to Figure 1-6 As shown, this embodiment provides a pulverizing device for processing herbal foods, including a hopper 1, a pulverizer body 2, and a drive module 4. The pulverizer body 2 has a pulverizing chamber 21 and a discharge chamber 22 that are interconnected. A hammer assembly 23 is rotatably mounted in the pulverizing chamber 21, and a discharge assembly 24 is rotatably mounted in the discharge chamber 22. The drive module 4 drives the hammer assembly 23 and the discharge assembly 24 to rotate. The pulverizer body 2 has an inlet 25 and an outlet 26, which are respectively connected to the pulverizing chamber 21 and the discharge chamber 22. The hopper 1 is inclined downwards towards the inlet 25 and is connected to the inlet 25. A support column 11 is fixed to the bottom of the hopper 1, and the support column 11 is fixed above the pulverizing chamber 21.

[0047] Material enters the grinding chamber 21 through the feed inlet 25 from the feed tray. The drive module 4 drives the hammer assembly 23 to pound the material in the grinding chamber 21. The discharge assembly 24 blows air towards the discharge outlet 26 in the discharge chamber 22 to create negative pressure. The airflow enters through the feed inlet 25, passes through the grinding chamber 21 and the discharge chamber 22, and flows out through the discharge outlet 26, extracting the powder in the grinding chamber 21. At the same time, the feed inlet 25 provides a force to the material in the feed tray in the direction of the feed inlet 25. With the downwardly inclined feed tray, automatic feeding of material is achieved. The support column 11 is located above the grinding chamber 21 to support the feed tray. While the hammer assembly 23 is working, it drives the grinding machine body 2 to vibrate. The support column 11 vibrates the feed tray to prevent material from clogging at the feed inlet 25, which would affect feeding and improve grinding efficiency.

[0048] Please refer to Figure 6As shown, the pulverizer further includes a controller 5. The feed inlet 25 is equipped with an electrically controlled material gate 27; the drive module 4 includes a drive motor 41 and a current sensor. The drive motor 41 drives the hammer assembly 23 and the discharge assembly 24 to rotate. The current sensor is electrically connected to the signal input terminal of the controller 5, transmitting the current value of the drive motor 41 to the controller 5. The output terminal of the controller 5 is electrically connected to the electrically controlled material gate 27, controlling the opening degree of the feed inlet 25 through the electrically controlled material gate 27. The current sensor monitors the current of the drive motor 41 in real time and transmits it to the controller 5. The controller 5 determines the severity of the blockage inside the pulverizer body 2 based on the current value of the drive motor 41, and controls the opening degree of the electrically controlled material gate 27 and the rotational speed of the drive motor 41 according to the severity of the blockage, controlling the feed rate and the pulverizing and discharging speed to ensure the stable operation of the pulverizer body 2 and avoid the feed rate exceeding the discharge rate, which could cause material blockage.

[0049] Furthermore, the drive module 4 also includes a voltage regulator, which is electrically connected to the drive motor 41 to provide a stable voltage to the drive motor 41 and reduce the impact of voltage fluctuations on the operating current of the drive motor 41.

[0050] Please refer to Figure 3 and Figure 4 As shown, a connecting pipe 32 is provided on the discharge port 26. The hopper 1 is connected to the connecting pipe 32 to form a feeding channel. The connecting pipe 32 guides the material to ensure that it can stably enter the grinding chamber 21. Furthermore, the hopper 1 is inclined downward toward the connecting pipe 32 at an angle of 3-5°. In this embodiment, the inclination angle is 4°. Similarly, the inclination angle can also be 3° or 5°. By limiting the inclination angle, it is avoided that the material falls too fast due to an excessively large inclination angle, causing blockage of the feed port 25. At the same time, it is also prevented that the resistance on the material increases due to an excessively small inclination angle, affecting the feeding efficiency.

[0051] Specifically, the electrically controlled material gate 27 includes an electric actuator 271 and a material gate 272. The electric actuator 271 is fixed to the outside of the connecting pipe 32 and electrically connected to the controller 5. The material gate 272 includes a drive section 2721 and an opening / closing section 2722. The drive section 2721 is located above the connecting pipe 32 and is fixedly connected to the drive end of the electric actuator 271. The opening / closing section 2722 extends downward between the hopper 1 and the connecting pipe 32. Under the drive of the controller 5, the electric actuator 271 drives the drive section 2721 to rise or fall, intelligently adjusting the material feeding speed.

[0052] Furthermore, a guide block 321 and a guide rod 322 are fixed to the outside of the connecting pipe 32. The guide rod 322 is inserted into the guide block 321 and fixedly connected to the drive section 2721. The guide rod 322 is connected to the material gate 272 and guides the rising and falling path of the material gate 272 through the guide block 321, ensuring that the material gate 272 can stably close the feeding side of the hopper 1 and open the feeding side of the hopper 1, ensuring stability during the feeding process.

[0053] Please refer to Figure 2 As shown, the drive module 4 further includes a bearing housing 42 and a drive spindle 43. The bearing housing 42 is fixed at both ends of the pulverizer body 2. The drive spindle 43 passes through the pulverizer body 2 and is rotatably connected to the bearing housing 42. A driven wheel 431 is fixed on the drive spindle 43, and a driving wheel 411 is provided at the drive end of the drive motor 41. A transmission component is connected between the driving wheel 411 and the driven wheel 431. In this embodiment, the transmission component is a transmission belt 412. The drive motor 41 controls the drive spindle 43 to rotate through the driving wheel 411, the transmission belt 412, and the driven wheel 431, thereby driving the hammer assembly 23 and the discharge assembly 24. The hammer assembly 23 is mounted on the drive spindle 43; the discharge assembly 24 includes multiple fan blades, which are fixed on the drive spindle 43. The drive spindle 43 drives the hammer assembly 23 to rotate, pounding the material. Simultaneously, it drives the fan blades to rotate, creating an airflow towards the discharge port 26, which extracts the powder from the grinding chamber 21. The hammer assembly 23 and the fan blades are mounted on the same drive spindle 43 and work simultaneously, reducing the complexity of the drive structure.

[0054] Please refer to Figure 5 As shown, specifically, an outwardly extending mounting portion 432 is fixed on the drive spindle 43. The mounting portion 432 is located inside the grinding chamber 21 and is fixed with a mounting rod 433. One end of the hammer assembly 23 is rotatably connected to the mounting rod 433. In this embodiment, there are four mounting rods 433. The hammer assembly 23 includes multiple hammers 231, and each hammer 231 has a mounting hole 232. The mounting rods 433 pass through the mounting holes 232. By setting multiple sets of mounting rods 433 to install the hammers 231, the hammer assembly 23 increases the frequency of hammering the material, improves the hammering effect, and makes the powder after grinding finer, thus improving the grinding effect.

[0055] Please refer to Figure 1-4As shown, the pulverizer body 2 further includes an upper cover 28 and a lower cover 29, which together form a pulverizing chamber 21 and a discharge chamber 22. In this embodiment, the upper cover 28 and the lower cover 29 are detachably connected by a connector 31, specifically a bolt and a nut. This facilitates opening the upper cover 28 to clean the powder in the pulverizing chamber 21 and the discharge chamber 22, and to inspect the internal components. An upper gear ring 281 and a lower gear ring 291 are respectively fixed inside the upper cover 28 and the lower cover 29. The upper gear ring 281 and the lower gear ring 291 are located inside the pulverizing chamber 21 and enclose the hammer assembly 23 within them. The upper gear ring 281 and the lower gear ring 291 cooperate with the hammer assembly 23 to pound and grind the material, further improving the pulverizing efficiency.

[0056] Furthermore, the pulverizer also includes a cooling module 6. A cooling channel 434 is provided inside the drive spindle 43; a cooling chamber 30 is formed between the lower cover 29 and the lower gear ring 291. The cooling module 6 is connected to the cooling pipes and the cooling chamber 30, supplying coolant to them. The coolant cools the drive spindle 43 and the lower gear ring 291, preventing the temperature of the connection point between the drive spindle 43 and the hammer assembly 23, and the lower gear ring 291, from rising over time and heating the material, thus avoiding nutrient loss from the food powder.

[0057] Specifically, the cooling module 6 includes a water tank 61, a gear pump 62, an inlet pipe 63, and an outlet pipe 64. The pulverizer body 2 is fixed to the water tank 61. The inlet end of the gear pump 62 is connected to the water tank 61. One end of the inlet pipe 63 is connected to the outlet end of the gear pump 62, and the other end of the inlet pipe 63 is connected to one side of the cooling chamber 30 and to one end of the cooling channel 434 via a rotary joint 65. One end of the outlet pipe 64 is connected to the other side of the cooling chamber 30 and to the other end of the cooling channel 434 via a rotary joint 65; the other end of the outlet pipe 64 is connected to the water tank 61. This achieves the recycling of coolant and reduces cooling costs. Furthermore, the drive end of the gear pump 62 is equipped with a secondary drive wheel 621, and the drive end of the drive motor 41 is also equipped with a main drive wheel 413. The main drive wheel 413 and the secondary drive wheel 621 are connected by a transmission belt 412. The pulverizer body 2 and the cooling module 6 share the drive motor 41. When the pulverizer body 2 is working, the cooling device works simultaneously, reducing the complexity of the drive structure and lowering costs. It also avoids energy waste caused by the cooling device working alone.

[0058] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
