[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0033] like Figure 1-10As shown, a device for crushing ultrapure benzethonium chloride finished product with adjustable particle size comprises a base shell 1 and an inner cylinder 2 rotatably arranged therein, wherein a feed inlet 11, a grinding chamber 12, a material drop channel 13 and a discharge port 14 which are connected in sequence are vertically opened in the base shell 1, and the inner cylinder 2 is provided with:

[0034] The grinding assembly 3 is located in the grinding chamber 12. The grinding assembly 3 includes a plurality of mounting rings 31 arranged in an axial array along the inner cylinder 2. The mounting rings 31 are arranged in a circumferential array with movable parts 32. The movable parts 32 are arranged to slide along the radial direction of the inner cylinder 2. The movable parts 32 are provided with grinding teeth 321. The grinding teeth 321 face the inclined inner wall of the grinding chamber 12.

[0035] The threaded rod 41, the adjusting rod 42 and the worm spring 43 are coaxially threadedly installed in the inner cylinder 2. The two ends of the worm spring 43 are respectively connected to the threaded rod 41 and the adjusting rod 42. The adjusting rod 42 is driven to rotate to drive the threaded rod 41 to rotate through the worm spring 43, and the threaded rod 41 moves axially upward relative to the inner cylinder 2 to drive the plurality of movable parts 32 to slide, and the grinding teeth 321 move closer relative to the inner wall of the grinding chamber 12.

[0036] Specifically, Figure 2 As shown, a feed port 11, a grinding chamber 12, a feeding channel 13 and a discharge port 14 are vertically provided on the base shell 1 from top to bottom, and the mounting ring 31 and the movable part 32 of the grinding assembly 3 are both located in the grinding chamber 12, and the inner wall of the grinding chamber 12 is inclined. When the inner cylinder 2 drives the grinding assembly 3 to rotate circumferentially in the base shell 1, raw material particles are put in from the feed port 11, so that the raw material particles enter the grinding chamber 12 and are ground by the axial movement of the grinding teeth 321 of the movable part 32, and then the raw material particles after grinding are gradually reduced until the raw material particles are smaller than the gap between the bottom of the grinding chamber 12 and the movable part 32, and the product particles fall along the feeding channel 13 and are discharged from the discharge port 14 to complete the grinding operation, and multiple sets of mounting plates and movable parts 32 of the grinding assembly 3 are used to grind the raw material in the grinding chamber 12, thereby improving the grinding efficiency and the uniformity of the particle size of the finished ground product.

[0037] Furthermore, it also includes a sliding rod 44, which is slidably arranged in a sliding hole 421 opened on the adjusting rod 42, a first end of a worm spring 43 is fixedly connected to the threaded rod 41, and a second end of the worm spring 43 is fixedly connected to the sliding rod 44. Figure 2As shown, the threaded rod 41 is threadedly installed in the inner cylinder 2, and the adjusting rod 42 is also threadedly installed in the inner cylinder 2. The outer end of the worm spring 43 is the first end, and the inner end is the second end. The outer end of the worm spring 43 is fixedly connected to the threaded rod 41, and the inner end of the worm spring 43 is fixedly connected to the sliding rod 44. The adjusting rod 42 can be manually rotated to drive the sliding rod 44 to rotate. At this time, the sliding rod 44 rotates to drive the worm spring 43 to deform as a whole, and the deformation elastic force of the worm spring 43 can drive the threaded rod 41 to rotate axially relative to the inner cylinder 2, and the threaded rod 41 is also threadedly matched with the inner cylinder 2. Therefore, the threaded rod 41 can be driven to move axially relative to the inner cylinder 2 by rotating the adjusting rod 42, and the threaded rod 41 moves axially to rise to drive A plurality of movable parts 32 are driven to slide radially along the inner cylinder 2. The movable parts 32 slide so that the grinding teeth 321 move closer to the inclined inner wall of the grinding chamber 12. The grinding degree of the raw material particles in the grinding chamber 12 is achieved by adjusting the distance between the grinding teeth 321 and the inclined inner wall of the grinding chamber 12, thereby adjusting the particle size of the obtained ground product. The movable parts 32 of the grinding assembly 3 are driven to slide radially along the inner cylinder 2 by using the adjusting rod 42, the spiral spring 43 and the threaded rod 41, so that the distance between the grinding teeth 321 and the inner wall of the grinding chamber 12 is adjusted by the adjusting rod 42, and then different degrees of grinding operations can be performed on the product raw materials, thereby achieving the regulation of the particle specifications of the ground products and improving the applicability of the grinding equipment.

[0038] Among them, a contact sensor and a cylinder can be set in the inner tube 2. When the threaded rod 41 rises axially relative to the inner tube 2, the contact sensor triggers the cylinder to run to drive the movable part 32 to slide. Furthermore, the contact sensor is used in conjunction with a motor and a gear rack to realize that the threaded rod 41 drives the movable part 32. Alternatively, other driving structures known to those skilled in the art that can drive the movable part 32 to slide when the threaded rod 41 rises axially can be replaced.

[0039] Furthermore, a rubber connector 35 is fixedly connected to the movable member 32. Since the movable members 32 are arranged in a circular array on the mounting ring 31, when the threaded rod 41 moves upward axially relative to the inner cylinder 2, the plurality of movable members 32 slide in the direction opposite to the axis of the inner cylinder 2, thereby causing the plurality of movable members 32 to expand outward. At this time, the two ends of the rubber connector 35 are respectively fixedly connected to the two movable members 32, and the rubber connector 35 is stretched under tension to prevent the grinding particles from falling into the inner cylinder 2 and causing the problem of material jamming, thereby improving the stability of the grinding operation.

[0040] In the above technical scheme, multiple groups of mounting plates and movable parts 32 of the grinding assembly 3 are used to grind the raw materials in the grinding chamber 12, thereby improving the grinding efficiency and the uniformity of the particle size of the finished ground product. Secondly, the adjusting rod 42, the spiral spring 43 and the threaded rod 41 are used to drive the movable part 32 of the grinding assembly 3 to slide radially along the inner cylinder 2, so that the distance between the grinding teeth 321 and the inner wall of the grinding chamber 12 is adjusted through the adjusting rod 42, and then different degrees of grinding operations can be performed on the product raw materials, thereby realizing the regulation of the particle specifications of the finished ground product and improving the applicability of the grinding equipment.

[0041] As another embodiment provided by the present invention, a sliding seat 92 is vertically slidably arranged in the base shell 1, a driving motor 91 is arranged on the sliding seat 92, an output end of the driving motor 91 is fixedly connected to the threaded rod 41, a mounting through hole 422 for fixedly connecting with the inner cylinder 2 is opened on the adjusting rod 42, and the threaded rod 41 is driven to rotate axially to drive the inner cylinder 2 and the threaded rod 41 to rotate synchronously.

[0042] Specifically, Figure 2As shown, the sliding seat 92 is vertically slidably arranged in the base shell 1, and the driving motor 91 is fixedly connected to the sliding seat 92. First, the adjusting rod 42 is rotated to drive the threaded rod 41 to move axially relative to the inner cylinder 2, thereby adjusting the distance between the grinding teeth 321 of the movable part 32 and the inclined inner wall of the grinding chamber 12. Then, the adjusting rod 42 can be fixedly locked relative to the inner cylinder 2 through bolts and mounting through holes 422. At this time, the output end of the driving motor 91 rotates clockwise to drive the threaded rod 41 to rotate axially, and there is friction between the threaded rod 41 and the inner cylinder 2, and the threaded rod 41 can drive the adjusting rod 42 and the inner cylinder 2 to rotate synchronously axially through the worm spring 43, thereby making the inner cylinder 2 and the grinding assembly 3 rotate synchronously to grind the raw material particles in the grinding chamber 12. During the grinding operation, the raw material particles in the grinding chamber 12 may get stuck, resulting in an increase in the rotational resistance of the inner cylinder 2. When the driving motor 91 drives the threaded rod 41, the inner cylinder 2 and the adjusting rod 42 to perform synchronous axial rotation, if there are large particles in the grinding chamber 12 and the rotation of the inner cylinder 2 is stuck, the torque applied by the driving motor 91 to the threaded rod 41 will cause the threaded rod 41 to move axially upward relative to the inner cylinder 2 and drive the spiral spring 43 to deform and absorb elastic potential energy, while the driving motor 91 and the sliding seat 92 slide vertically upward following the threaded rod 41. At this time, the movable part 32 is driven to slide out due to the rise of the threaded rod 41, so that the grinding teeth 321 move to squeeze the particles in the grinding chamber 12. The raw material particles are crushed to reduce the rotational resistance of the inner cylinder 2. Subsequently, the worm spring 43 is deformed to release elastic potential energy so that the threaded rod 41 moves axially downward relative to the inner cylinder 2 to reset. The driving motor 91 and the sliding seat 92 also slide downward vertically to reset. The movable part 32 also slides toward the axis of the inner cylinder 2 to reset to the original position to continue the grinding operation. The driving motor 91, the sliding seat 92, the threaded rod 41 and the worm spring 43 are used to realize that when the inner cylinder 2 is rotationally stuck, the movable part 32 can slide out so that the grinding teeth 321 can squeeze and crush the stuck raw material particles, thereby reducing the rotational resistance of the inner cylinder 2, avoiding the jamming problem in the grinding operation, and improving the grinding stability.

[0043] The electrical connection and the driving program of the driving motor 91 are common technical knowledge to those skilled in the art and will not be elaborated herein.

[0044] As another embodiment provided by the present invention, the grinding assembly 3 also includes a rotating ring 33 and a connecting rod 34. The rotating ring 33 is rotatably set on the first thrust ring 411 of the threaded rod 41, the first end of the connecting rod 34 is rotatably set on the rotating ring 33, and the second end of the connecting rod 34 is rotatably set on the sliding portion 322 of the movable part 32. The threaded rod 41 is driven to move axially relative to the inner cylinder 2 so that the first thrust ring 411 pushes the rotating ring 33 to move axially, and the rotating ring 33 pushes the movable part 32 to slide radially along the inner cylinder 2 through the connecting rod 34.

[0045] Specifically, Figure 5 As shown, the rotating ring 33 is rotatably set on the first push ring 411 of the threaded rod 41, and the movable part 32 is slidably set on the mounting ring 31 along the radial direction of the inner cylinder 2 through the sliding part 322. The end of the connecting rod 34 facing the axis of the inner cylinder 2 is the first end, and the end of the connecting rod 34 facing away from the axis of the inner cylinder 2 is the second end. The rotating ring 33 is rotatably set on the first push ring 411 of the threaded rod 41, the first end of the connecting rod 34 is rotatably set on the rotating ring 33, and the second end of the connecting rod 34 is rotatably set on the sliding part 322 of the movable part 32. When the threaded rod 41 moves upward axially relative to the inner cylinder 2, the first push ring 411 of the threaded rod 41 pushes the rotating ring 33 to move upward vertically, and during the upward movement of the rotating ring 33, the second end of the connecting rod 34 is pushed toward the mounting ring 31, so that the rotating ring 33 and the connecting rod 34 are used to realize the driving of the movable part 32 by the threaded rod 41, without the need for additional driving, simplifying the transmission structure, and improving the stability of the driving of the movable part 32 by the threaded rod 41.

[0046] As another embodiment provided by the present invention, an annular locking portion 21 is provided in the inner cylinder 2, and a movable groove 412 is provided on the first push ring 411 at the lowest position of the threaded rod 41. The threaded rod 41 is in a default state so that the lowest rotating ring 33 abuts against the inner side of the locking portion 21. The threaded rod 41 is driven to move axially relative to the inner cylinder 2 to the highest position of the stroke so that the rotating ring 33 disengages from the locking portion 21, and the rotating portion 331 of the rotating ring 33 is located in the movable groove 412 so that the lowest mounting ring 31 and the rotating ring 33 can move radially along the inner cylinder 2.

[0047] Specifically, Figure 4 As shown, three groups of mounting rings 31 and movable parts 32 are arranged vertically on the inner tube 2. Figure 5 As shown, three first push rings 411 are also provided on the threaded rod 41, and the first push ring 411 at the bottom vertically is the lowest first push ring 411, which is provided with a movable groove 412. Figure 2As shown, the movable part 32 arranged on the vertically lowest mounting ring 31 is located at the vertically lowest part of the grinding chamber 12, and the rotating part 331 of the mounting ring 31 is located in the movable groove 412. When the threaded rod 41 is in the default state and the movable part 32 does not extend toward the inner wall of the grinding chamber 12, the mounting ring 31 is located at the inner ring side of the locking part 21 to be resisted, so that the mounting ring 31 and the movable part 32 thereon are both kept coaxial with the inner cylinder 2; and when the grinding chamber 12 is stuck during the grinding process, the threaded rod 41 is driven to gradually move upward along the axial direction of the inner cylinder 2 until the threaded rod 41 moves up to form the highest position, and the rotating ring 33 also moves vertically upward and breaks away from the inner side of the locking part 21. At this time, the rotating ring 33 is no longer limited by the locking part 21, so that the group of mounting rings 31, the movable part 32 and the rotating ring 33 on the lowest side can perform any horizontal movement as a whole. When the inner cylinder 2 rotates, due to the group of mounting rings close to the lowest side of the grinding chamber 12 The mounting ring 31, the movable part 32 and the rotating ring 33 can move horizontally as a whole. The mounting ring 31, the movable part 32 and the rotating ring 33 will be subjected to the resistance of the viscous granular material in the grinding chamber 12 and move horizontally, so that the mounting ring 31 and the movable part 32 are no longer coaxial with the inner cylinder 2. Therefore, the mounting ring 31 is driven by the rotation of the inner cylinder 2 to produce eccentric rotation, so that the grinding teeth 321 on the movable part 32 will randomly scrape against the inner wall of the lower side of the grinding chamber 12, and the larger scraping force brought by the eccentric rotation is used to remove the viscous material on the lower side of the grinding chamber 12, thereby avoiding the problem of material jamming on the lower side of the grinding chamber 12 and improving the grinding stability. Secondly, since the powdery particles are arbitrarily pressed and adhere to the inner wall of the grinding chamber 12 in the form of sheets, the eccentrically rotating mounting ring 31 and the movable part 32 can scrape off the flaky aggregated granular material adhered to the inner wall of the grinding chamber 12, thereby reducing the material discharge resistance and improving the grinding efficiency. When the resistances experienced by the movable part 32 on the upper side of the mounting ring 31 are equal, the mounting ring 31 is easily affected by the rotational force of the inner cylinder 2 and the force of the spiral spring 43 driving the threaded rod 41 downward, so that the mounting ring 31 and the rotating ring 33 are reset to be coaxial with the inner cylinder 2. Then, the threaded rod 41 moves axially downward relative to the inner cylinder 2 to reset, so that the movable part 32 slides and resets.

[0048] As another embodiment provided by the present invention, a heating ring 5 is disposed in the base shell 1 , and a heat conducting inclined plate 51 extending into the material drop channel 13 is arranged in a circumferential array on the heating ring 5 , and the heat conducting inclined plate 51 is partially spiral.

[0049] Specifically, Figure 2As shown, a heating ring 5 is provided in the base shell 1, and a heating component is provided in the heating ring 5. The heating component can be replaced by heating components known to those skilled in the art, such as electric heating wires, semiconductor heating plates or hot air pipes. The heating component is a technical common sense known to those skilled in the art and will not be elaborated here. The heating ring 5 is provided with a heat-conducting inclined plate 51 extending into the drop channel 13. The heat-conducting inclined plate 51 is partially spiral. When the ground material in the grinding chamber 12 falls into the drop channel 13, the material will fall onto the heat-conducting inclined plate 51, and then roll along the heat-conducting inclined plate 51 to fall into the discharge port 14 for discharge. Since the raw material particles will inevitably contain some moisture, when the material particle size is small after grinding and contains moisture, it is easy to stick to each other and compact. The heat-conducting inclined plate 51 is used to heat and dry the ground material, thereby avoiding the product material after grinding from compacting or sticking to the drop channel 13 due to moisture, which is convenient for discharging and processing of the ground product. Secondly, the moisture of the product material in the material drop channel 13 will evaporate due to the heat and enter the grinding chamber 12, so that the water vapor rises and is discharged from the feed port 11. At the same time, part of the water vapor is easy to adhere to the granular material in the grinding chamber 12, thereby reducing the hardness of the granular material in the grinding chamber 12, facilitating the material grinding operation in the grinding chamber 12 and improving the grinding efficiency.

[0050] As another embodiment provided by the present invention, each of the plurality of movable parts 32 at the lowest position is provided with a flexible column 323 , and the flexible column 323 vertically extends to abut against the heat conduction inclined plate 51 .

[0051] Specifically, Figure 6 As shown, a plurality of movable members 32 on the lowest vertical group of mounting rings 31 are provided with flexible columns 323, and as shown in FIG. Fig. 9As shown, the flexible column 323 extends vertically downward to abut against the heat-conducting inclined plate 51, and when the grinding chamber 12 is stuck during the grinding process, the threaded rod 41 is driven to gradually move upward along the axial direction of the inner cylinder 2, until the threaded rod 41 moves up to form the highest position, and the rotating ring 33 also moves vertically upward and disengages from the inner side of the locking portion 21. At this time, the rotating ring 33 is no longer limited by the locking portion 21, so that the group of mounting rings 31, movable parts 32 and rotating rings 33 on the lower side can move horizontally as a whole. When the inner cylinder 2 rotates, since the group of mounting rings 31, movable parts 32 and rotating rings 33 near the lower side of the grinding chamber 12 can move horizontally as a whole, the group of mounting rings 31, movable parts 32 and rotating rings 33 will be subject to the resistance of the viscous granular material in the grinding chamber 12 and move horizontally, so that the mounting rings 31 and The movable part 32 is no longer coaxial with the inner cylinder 2, so the mounting ring 31 is driven by the rotation of the inner cylinder 2 to produce eccentric rotation, and during the overall horizontal movement of the mounting ring 31, the movable part 32 and the rotating ring 33, a number of flexible columns 323 will randomly scrape or pass over the upper surface of the heat-conducting inclined plate 51, so as to use the flexible columns 323 to scrape and remove the product materials adhering to the heat-conducting inclined plate 51, avoid the problem of material particles adhering to the heat-conducting inclined plate 51 and cause material jamming, and improve the stability of material discharge. Secondly, the scraping and contact between the flexible columns 323 and the heat-conducting inclined plate 51 will generate horizontal shaking force on the mounting ring 31, the movable part 32 and the rotating ring 33, thereby further improving the scraping and cleaning efficiency of the movable part 32 of the group on the inner wall of the grinding chamber 12, and further improving the cleaning effect of stuck or adhered materials.

[0052] As another embodiment provided by the present invention, a rotating seat 6 is arranged on the inner cylinder 2, and a fan blade portion 63 is arranged in a circumferential array on the rotating seat 6. A connected air inlet 15 and a jet duct 16 are opened on the base shell 1. The fan blade portion 63 extends between the air inlet 15 and the jet duct 16. The first end of the jet duct 16 is connected to the grinding chamber 12 and is inclined toward the grinding teeth 321.

[0053] Specifically, Figure 8 As shown, the upper end opening of the jet channel 16 is the first end, and the first end opening of the jet channel 16 is arranged vertically and tilted downward, as shown in FIG. Figure 2As shown, an air inlet 15 and an air jet 16 are provided on the base shell 1, and the fan blade portion 63 of the rotating seat 6 extends between the air inlet 15 and the air jet 16. When the threaded rod 41 drives the inner cylinder 2 and the adjusting rod 42 to rotate synchronously along the axis, the rotating seat 6 rotates synchronously with the inner cylinder 2, so that the fan blade portion 63 rotates to draw external air from the air inlet 15 and fill the air into the grinding chamber 12 along the air jet 16. The fan blade portion 63, the air inlet 15 and the air jet 16 are used to apply a vertical downward airflow thrust to the grinding chamber 12, and then the airflow is used to blow the materials with smaller particle volume in the grinding chamber 12 into the material discharge channel 13, thereby improving the stability and speed of material discharge and avoiding the problem of uneven particle size caused by repeated grinding of small particle materials, thereby improving the particle uniformity of the formed product, and reducing the problem of material jamming caused by small particle materials sticking to the inner wall of the grinding chamber 12 or the grinding teeth 321, thereby improving the stability of the grinding operation.

[0054] As another embodiment provided by the present invention, a connecting portion 62 extending through the material channel 13 is provided on the rotating seat 6 , and a chamfer is provided on the top of the connecting portion 62 to form an abutment tip 621 located in the material channel 13 .

[0055] Specifically, Fig. 9 As shown, the rotating seat 6 is provided with a mounting portion 61 and a connecting portion 62, and the connecting portion 62 passes through the material drop channel 13 so that the contact tip 621 is located in the material drop channel 13. During the grinding operation, the small particles of the ground material are easily agglomerated or pressed into sheets due to the grinding pressure. When the agglomerated material or sheet material falls from the material drop channel 13 to the discharge port 14, the inner cylinder 2 drives the rotating seat 6 to rotate so that the contact tip 621 is located in the material drop channel 13 and moves and rotates circumferentially. At this time, the contact tip 621 can break up the falling agglomerated material or sheet material, so that the product material falling at the discharge port 14 is in powder form, which is convenient for the processing of the molded product and improves the overall uniformity of the molded product.

[0056] As another embodiment provided by the present invention, the rotating seat 6 is axially slidably arranged on the inner cylinder 2, a second thrust ring 413 is arranged on the threaded rod 41, the spiral direction of the heat conductive inclined plate 51 is in the same direction as the rotation and grinding direction of the inner cylinder 2, the threaded rod 41 is driven to move axially relative to the inner cylinder 2 so that the second thrust ring 413 pushes the rotating seat 6 to slide up, and the contact tip 621 moves vertically upward to contact the heat conductive inclined plate 51.

[0057] Specifically, the rotating seat 6 is arranged to slide along the axial direction of the inner cylinder 2, and the driving motor 91 drives the threaded rod 41 to drive the inner cylinder 2 and the adjusting rod 42 to rotate clockwise to perform the grinding operation, and the spiral inclination direction of the heat conduction inclined plate 51 is also clockwise. In the process of the driving motor 91 driving the threaded rod 41, the inner cylinder 2 and the adjusting rod 42 to perform synchronous axial rotation, if there are large particles in the grinding chamber 12 and the rotation of the inner cylinder 2 is stuck, the torque applied by the driving motor 91 to the threaded rod 41 will cause the threaded rod 41 to move axially upward relative to the inner cylinder 2 and drive the spiral spring 43 to deform and absorb elastic potential energy, and the driving motor 91 and the sliding seat 92 follow the threaded rod 41 to slide vertically upward. At this time, due to the rise of the threaded rod 41, the movable part 32 is driven to slide out so that the grinding teeth 321 move to squeeze the raw material particles in the grinding chamber 12, and in the process of the axial movement and rise of the threaded rod 41, The second push ring 413 pushes the mounting portion 61 of the rotating seat 6 to drive the rotating seat 6 to slide upward vertically, thereby causing the contact tip 621 to move vertically upward to approach the heat conduction inclined plate 51, and the contact tip 621 moves vertically upward to squeeze the lower side surface of the heat conduction inclined plate 51 to apply a counterclockwise thrust to the inner cylinder 2, thereby achieving that when the inner cylinder 2 is stuck during the grinding process, the contact tip 621 can move upward to contact the pressurized heat conduction inclined plate 51 and cause the inner cylinder 2 to rotate in the opposite direction to loosen the stuck material, thereby further avoiding the problem of material jamming during the grinding process and improving the stability of the grinding operation; secondly, during the reverse counterclockwise rotation of the inner cylinder 2, the spiral spring 43 further deforms to store elastic potential energy so that the inner cylinder 2 can generate a greater grinding force when resuming the positive clockwise rotation grinding, thereby grinding and crushing the stuck material and improving the grinding efficiency and grinding uniformity.

[0058] Further, such as Fig. 9 As shown, a rotating bearing 81 and a rubber sealing ring 82 are provided in the base shell 1 between the heating ring 5 and the rotating seat 6. The rotating bearing 81 is located on the side close to the heating ring 5, and the rubber sealing ring 82 is fixedly connected to the rotating seat 6. When the rotating seat 6 is driven by the threaded rod 41 to slide axially, the rubber sealing ring 82 is squeezed and deformed to cooperate with the sliding of the rotating seat 6.

[0059] Working principle: First, the adjusting rod 42 is rotated to drive the threaded rod 41 to move axially relative to the inner cylinder 2, and then the distance between the grinding teeth 321 of the movable part 32 and the inclined inner wall of the grinding chamber 12 is adjusted. Then, the adjusting rod 42 can be fixed and locked relative to the inner cylinder 2 through bolts and mounting holes 422. At this time, the output end of the driving motor 91 rotates clockwise to drive the threaded rod 41 to rotate axially, and there is friction between the threaded rod 41 and the inner cylinder 2, and the threaded rod 41 can drive the adjusting rod 42 and the inner cylinder 2 to rotate axially synchronously through the worm spring 43, so that the inner cylinder 2 and the grinding assembly 3 rotate synchronously to grind the raw material particles in the grinding chamber 12. During the grinding operation, the raw material particles in the grinding chamber 12 may get stuck, resulting in an increase in the rotational resistance of the inner cylinder 2. When the driving motor 91 drives the threaded rod 41, the inner cylinder 2 and the adjusting rod 42 to perform synchronous axial rotation, if there are large particles in the grinding chamber 12 and the rotation of the inner cylinder 2 is stuck, the torque applied by the driving motor 91 to the threaded rod 41 will cause the threaded rod 41 to move axially upward relative to the inner cylinder 2 and drive the worm spring 43 to deform and absorb elastic potential energy, and the driving motor 91 and the sliding seat 92 follow the threaded rod 41 to slide vertically upward. At this time, due to the rise of the threaded rod 41, the movable part 32 is driven to slide out so that the grinding teeth 321 move to squeeze the raw material particles in the grinding chamber 12, thereby crushing the stuck raw material particles to reduce the rotational resistance of the inner cylinder 2, and then the worm spring 43 is deformed to release the elastic potential energy so that the threaded rod 41 moves upward relative to the inner cylinder 2. The cylinder 2 axially moves downward to reset, the driving motor 91 and the sliding seat 92 also slide downward vertically to reset, and the movable part 32 also slides toward the axis of the inner cylinder 2 to reset to the original position to continue the grinding operation. When the ground material in the grinding chamber 12 falls into the material drop channel 13, the material will fall onto the heat-conducting inclined plate 51 for heating, and then roll along the heat-conducting inclined plate 51 to fall into the discharge port 14, and then complete the discharge of the heat-conducting inclined plate 51 to heat and dry the ground material. The rotating seat 6 rotates synchronously with the inner cylinder 2, so that the fan blade part 63 rotates to draw in external air from the air inlet 15 and fill the air into the grinding chamber 12 along the jet channel 16, and the fan blade part 63, the air inlet 15 and the jet channel 16 are used to achieve a vertical downward airflow thrust on the grinding chamber 12, and then the airflow is used to blow the material with smaller particle volume in the grinding chamber 12 into the drop channel 13.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
