The hollow pulverizing blades are provided in the above device, and nitrogen is introduced into the hollow pulverizing blades when pulverizing frozen cheese.

[0004] The present invention aims to solve the technical problems existing in the prior art and provides an energy-saving frozen cheese pulverizing device and a pulverizing method thereof to solve the problems that the pulverizing mechanism of the existing device is relatively simple and mainly relies on the rotation of hollow pulverizing blades for pulverizing, which makes it difficult to achieve multi-stage and fine pulverization of frozen cheese, resulting in poor uniformity of the particle size of the pulverized material and inability to meet the diverse requirements of material particle size in different downstream processing scenarios. In addition, the existing device lacks adaptive adjustment capabilities when dealing with frozen cheeses of different hardness or viscosity, and the angle and spacing of the pulverizing blades are fixed, which makes it easy for the material to be blocked or over-pulverized, and the versatility and reliability of the equipment are limited.

[0005] The technical solution of the present invention to solve the above technical problems is as follows: an energy-saving pulverizing device for frozen cheese, comprising a motor, a crushing frame and an active bevel gear, a turning cylinder and a core shaft driven by the motor, an inner cylinder fixedly installed on the inner side of the turning cylinder, a reciprocating drive system is provided on the inner side of the inner cylinder and a hollow shaft is rotatably installed, the reciprocating drive system is transmission-connected to the crushing frame, the crushing frame moves back and forth along the axis direction of the turning cylinder and its displacement frequency and displacement stroke are cyclically switched in three modes, the hollow shaft is linked to the core shaft and the hollow shaft alternately rotates in the first cycle, idles in the first cycle, rotates in the second cycle and idles in the second cycle, the two ends of the turning cylinder are respectively connected to the crushing cylinder and the crushing cylinder, and the crushing cylinder and the crushing cylinder are both connected Driven by the active bevel gear, a group of elastic pressure parts are installed between the rolling frame and the crushing frame, a rotating milling hammer is rotatably installed on the rolling frame, and a crushing shaft is rotatably installed on the crushing frame. The rotating milling hammer and the crushing shaft are driven by a hollow shaft. A plurality of knife rings distributed along the axial direction of the crushing shaft are slidably connected to the crushing shaft. A follower spring and a group of corrugated bars are connected between each knife ring and between the two outermost knife rings and the crushing shaft. Four crushing knives are rotatably installed on each knife ring, and four racks are fixedly installed on the inner side of the crushing shaft. The bottom end of each crushing knife is provided with a driven gear, and each driven gear is connected to a rack at the corresponding position. A knife distance adjustment system for cyclically changing the distance between the two knife rings is provided on the inner side of the crushing shaft.

[0006] The beneficial effects of the present invention are: 1. The present invention realizes a multi-stage refined pulverizing process of "crushing, coarse crushing, and fine crushing" through multi-dimensional collaborative design. Specifically: the double-drum linkage design forms a continuous processing system of first crushing and then crushing. The rotary hammers in the crushing drum first crush the large blocks of frozen cheese into particles, and then transfer them to the crushing drum for secondary crushing through the flip drum, thus repeating the crushing and crushing process in a cycle. The "short stroke high frequency, medium stroke medium frequency, long stroke low frequency" three-mode reciprocating movement of the crushing frame, combined with the cyclic drive of the hollow shaft "rotating for 4 seconds, idling for 1 second, rotating for 3 seconds, and idling for 1 second", enables the crushing knife to form three-dimensional cutting under the conditions of rotation, rotation, reciprocation and changes in axial spacing.

[0007] 2. In the present invention, the blade spacing adjustment system drives the reciprocating screw to rotate periodically through the differential gear, half-tooth gear and reverse torsion spring, so that the blade ring spacing changes dynamically with the material properties. When the material is hard, the spacing is reduced to enhance shearing, and when the material is sticky, the spacing is increased to reduce adhesion. The angle of the crushing knife is driven by the rack and driven gear mechanism to change cyclically to avoid local wear and adapt to different material properties. The displacement mode of the crushing frame is linked with the periodic rotation of the hollow shaft to further automatically adjust the force according to the material state.

[0008] 3. This invention innovatively integrates the refrigeration system with the transmission system, solving the problem of energy waste caused by over-refrigeration in traditional devices. The refrigeration module introduces low-temperature airflow into the flip cylinder through the air guide duct. The temperature probe monitors in real time and feeds back to the PLC controller, dynamically adjusting the cooling capacity to achieve on-demand cooling.

[0009] 4. The present invention breaks through the bottleneck of "single-stage processing and low efficiency" of traditional devices through the precise coordination of various functional modules. The crushing and pulverizing processes are carried out simultaneously. The periodic rotation of the hollow shaft drives the rotary hammer and the pulverizing shaft at the same time. The "revolution, rotation and reciprocation" of the pulverizing knife forms a three-dimensional motion. Combined with the dynamic adjustment of the knife ring spacing, the material can be cut in multiple dimensions in the same pulverizing chamber, and the single processing capacity is improved compared with the traditional device.

[0022] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0023] The present invention provides the following preferred embodiments like Figure 1-11 As shown, a frozen cheese energy-saving crushing device includes a motor 1, a crushing frame 2, a driving bevel gear 10 driven by the motor 1, a turning cylinder 3 and a core shaft 4; It also includes a bracket 20, the motor 1 is fixedly mounted on the bracket 20, an outer sleeve shaft 21 is rotatably mounted on the bracket 20, the active bevel gear 10 is fixedly mounted on the outer sleeve shaft 21, a turning shaft 22 and a positioning shaft are mounted on the turning cylinder 3, the outer sleeve shaft 21 and the core shaft 4 are both rotatably connected to the turning shaft 22 through bearings, the output shaft end of the motor 1 is transmission-connected to three transmission toothed belts, the three transmission toothed belts are respectively transmission-connected to the core shaft 4, the turning shaft 22 and the outer sleeve shaft 21, and the positioning shaft is rotationally connected to the bracket 20 through bearings; The bracket 20 provides stable support for each transmission component. Three transmission toothed belts drive the core shaft 4, the turning shaft 22, and the outer shaft 21 to move synchronously, forming a multi-axis transmission system. The core shaft 4 is responsible for driving the reciprocating drive system and the transmission bevel wheel 32. The turning shaft 22 controls the angle adjustment of the turning drum 3 to match the feeding and discharging of materials. The outer shaft 21 drives the grinding drum 8 and the crushing drum 9 to work synchronously through the active bevel gear 10. This multi-path transmission design avoids the energy consumption problem of the traditional single-axis drive that requires frequent switching of power distribution, allowing each functional module to operate in coordination according to a preset rhythm. The system further includes a refrigeration module 23 and a PLC controller 24 mounted on the bracket 20. The air outlet of the refrigeration module 23 is connected to a refrigeration pipe 25. An air flow channel with two ends open and connected to the inner cavity of the flip cylinder 3 is fixedly formed inside the positioning shaft. The other end of the refrigeration pipe 25 is rotatably connected to the air flow channel. A temperature probe 26 is installed on the refrigeration pipe 25 to monitor the temperature of the inner cavity. The data end of the temperature probe 26 is connected to the PLC controller 24. The refrigeration module 23 continuously delivers low-temperature air to the inner cavity of the tumbling drum 3 through the refrigeration pipe 25 and the air guide channel. The temperature inside the refrigeration pipe 25 is monitored in real time by the temperature probe 26 and fed back to the PLC controller 24. The refrigeration capacity can be dynamically adjusted according to the actual temperature demand of the frozen cheese. When the temperature probe 26 detects that the airflow temperature is higher than the maintenance temperature of the frozen cheese, the PLC controller 24 controls the refrigeration module 23 to increase the power to maintain a constant temperature in the tumbling drum 3. This closed-loop temperature control system ensures that the cheese remains frozen during the pulverizing process to avoid sticking and clogging caused by thawing, while also avoiding energy waste caused by over-refrigeration, thus achieving the energy-saving goal of providing cooling on demand. At the same time, the plugs 27 at the bottom of the grinding cylinder 8 and the turning cylinder 3 are designed to facilitate the rapid cleaning of residual materials and prevent material agglomeration in low-temperature environments that affects the subsequent pulverization effect. An inner cylinder 5 is fixedly mounted on the inner side of the turning cylinder 3. A reciprocating drive system is provided on the inner side of the inner cylinder 5 and a hollow shaft 6 is rotatably mounted thereon. A crushing frame 7 is connected to the reciprocating drive system. The crushing frame 7 moves back and forth along the axis of the turning cylinder 3, and its displacement frequency and displacement stroke are cyclically switched in three modes. The reciprocating drive system includes a drive wheel 28 disposed on the inner side of the inner cylinder 5 and fixedly mounted on the core shaft 4. Three drive teeth 29 and three empty tooth reset portions 30 are alternately arranged on the drive wheel 28. Two positioning guide rails are installed on the inner cylinder 5. Both positioning guide rails are slidably connected to the crushing frame 7. A drive tooth plate 31 is installed on the crushing frame 7. The three drive teeth 29 alternately mesh with the drive tooth plate 31. In a single rotation cycle, the transmission stroke of the three drive teeth 29 on the drive tooth plate 31 increases gradually along the rotation direction of the drive wheel 28. A reset spring 45 is connected between the hollow shaft 6 and the crushing shaft 13. Along the rotation direction of the driving wheel 28, the central angles corresponding to the effective meshing areas on the three driving tooth portions 29 are 30°, 55° and 80° respectively, and the central angles corresponding to the three empty tooth reset portions 30 are all 65°; The number of teeth on the effective meshing area of ​​the three driving tooth parts 29 increases and the tooth pitch is the same; The three driving teeth 29 and the three empty tooth reset portions 30 on the driving wheel 28 are alternately engaged with the driving tooth plate 31, so that the reciprocating stroke of the crushing frame 7 presents a cyclic change mode of "short stroke high frequency reciprocating, medium stroke medium frequency reciprocating, long stroke low frequency reciprocating". The technical effects of this technical solution on the crushing and grinding process are as follows: When the center angle of the driving tooth portion 29 is small, the displacement stroke of the crushing frame 7 is short. At this time, the range of action of the crushing knife 17 is small, which is suitable for preliminary fine crushing of cheese and can crush larger pieces of cheese into smaller particles first. As the center angle of the driving tooth portion 29 gradually increases, the displacement stroke of the crushing frame 7 becomes longer, and the range of action of the crushing knife 17 is expanded. The cheese particles that have been preliminarily crushed can be more fully crushed for the second time, the third time and in a cycle to further reduce their particle size. This "short, medium and long" cyclic displacement stroke enables the crushing device to achieve multi-particle size graded crushing of cheese in the same crushing process, improve the crushing efficiency and crushing quality, and meet the requirements of cheese particle size for different subsequent processing.

[0024] In the "short, medium, and long" cyclic displacement mode, the crushing blade 17 does not continuously work at its maximum stroke. When the stroke is short, the load on the crushing blade 17 is relatively small. As the stroke gradually becomes longer, the load also gradually increases. This working mode allows the crushing blade 17 to have a certain buffer and rest, reducing excessive wear caused by continuous high-load operation, extending the service life of the crushing blade 17, and reducing equipment maintenance costs. Different displacement strokes will cause the crushing knife 17 to act on the cheese with different strengths and times. During the short stroke, the crushing knife 17 acts on the cheese at a high frequency in a smaller range, which can first break up the larger cheese blocks in the local area. During the medium and long strokes, the crushing knife 17 further crushes the cheese in a larger range, so that the cheese in the entire crushing chamber can be evenly crushed, avoiding the situation where some cheese is crushed too finely and some is not crushed sufficiently, thereby improving the uniformity of the crushed product.

[0025] The cyclical change of the reciprocating displacement stroke of the crushing frame 7 will drive the force exerted by the rotary grinding hammers 12 on the crushing frame 2 on the cheese during the crushing process to change accordingly. When the displacement stroke of the crushing frame 7 is short, the crushing force of the rotary grinding hammers 12 on the cheese is relatively small, which is suitable for preliminary compaction and pre-crushing of the cheese entering the crushing cylinder 8. As the displacement stroke becomes longer, the crushing force of the rotary hammer 12 gradually increases, and the pre-crushed cheese can be crushed more deeply. This cyclically changing crushing force can make the cheese more evenly stressed during the crushing process, avoiding excessive or uneven crushing of the cheese due to excessive local force. At the same time, it can also reduce the splashing of cheese during the crushing process, thereby improving the crushing efficiency and safety.

[0026] The "short, medium and long" cyclic displacement stroke enables the crushing device to automatically adjust the crushing force according to the actual state of the cheese, making it more adaptable; The reciprocating displacement of the crushing frame 7 not only affects the crushing process, but also cooperates with the crushing process. When the displacement of the crushing frame 7 is short, the crushing effect of the crushing knife 17 on the cheese is relatively weak. At this time, the rotary hammer 12 can fully crush the cheese, providing a more suitable material state for subsequent crushing work. When the displacement stroke of the crushing frame 7 becomes longer, the crushing effect of the crushing knife 17 is enhanced, and the crushed cheese can be further crushed into smaller particles; This collaborative working mode can improve the working efficiency of the entire crushing device, making the cheese crushing and pulverizing process smoother and more efficient; The specific displacements for short, medium, and long strokes are 5cm, 10cm, and 15cm respectively, and the specific frequency values ​​for high, medium, and low frequencies are 20Hz, 10Hz, and 5Hz; The refrigeration pipe 25 is made of 304 stainless steel, which is resistant to low temperature corrosion; The crushing knife 17 is made of hard alloy; The carbide coating of the crushing blade 17 contains MoS2 wear-resistant particles and is suitable for crushing high-fat cheese; The hollow shaft 6 is linked with the core shaft 4 and the hollow shaft 6 alternately rotates in a first cycle, idles in a first cycle, rotates in a second cycle, and idles in a second cycle; The periodic times corresponding to the first periodic rotation, the first periodic idling, the second periodic rotation and the second periodic idling are different; The duration of the first cycle rotation is 4 seconds, the duration of the first cycle idling is 1 second, the duration of the second cycle rotation is 3 seconds, and the duration of the second cycle idling is 1 second; The hollow shaft 6 further comprises a transmission bevel wheel 32 fixedly mounted on the core shaft 4, with two bevel tooth portions 33 and two toothless portions 34 alternately provided on the transmission bevel wheel 32. A passive bevel gear is fixedly mounted on the hollow shaft 6, with the two bevel tooth portions 33 alternately meshing with the passive bevel gear. Teeth are evenly distributed on each bevel tooth portion 33, and the center angles corresponding to the effective meshing sections of the two bevel tooth portions 33 differ by 30°. The center angles corresponding to the two toothless portions 34 are different. Specifically, the center angles corresponding to the effective meshing sections on the two bevel gear portions 33 are 100° and 70° respectively, and the center angles corresponding to the two toothless portions 34 are 80° and 110° respectively; The hollow shaft 6 is linked to the core shaft 4 and rotates in a first cycle of 4 seconds, idles in a first cycle of 1 second, rotates in a second cycle of 3 seconds, and idles in a second cycle. The two bevel teeth 33 of the transmission cone wheel 32 on the core shaft 4 have effective meshing sections with central angles of 100° and 70°, and the two toothless sections 34 have central angles of 80° and 110°, which alternately drive the passive bevel gear of the hollow shaft 6, so that the rotary hammer 12 and the crushing shaft 13 rotate cyclically according to this cycle. During the crushing stage, the first cycle of low-speed, high-torque rotation for 4 seconds can crush the hard shell of frozen cheese, and the second cycle of high-speed, small rotation for 3 seconds can compact the soft core. During the idling for 1 second, the elastic pressure member 11 lifts the rotary hammer 12 to reduce wear and accumulate potential energy to enhance the crushing force in the next cycle. During the crushing stage, the crushing shaft 13 drives the crushing knife 17 to form a three-dimensional cutting process of "revolution, rotation, and reciprocation" when rotating. The long rotation in the first cycle is combined with long-stroke coarse crushing, and the short rotation in the second cycle is combined with short-stroke fine crushing. When idling, the reciprocating motion of the crushing frame 7 causes the knife ring 14 to move axially to avoid material blockage. At the same time, the knife spacing adjustment system dynamically adjusts the spacing of the knife ring 14 when idling, and the rotation cycle of the rotary hammer 12 and the crushing shaft 13 is linked through the core shaft 4 to achieve synchronous crushing and crushing processes. The reciprocating screw 37 completes a forward and reverse rotation every 10 seconds, and the knife ring 14 spacing changes cyclically between 2cm-5cm; The two ends of the turning cylinder 3 are connected to the crushing cylinder 8 and the pulverizing cylinder 9 respectively, and the crushing cylinder 8 and the pulverizing cylinder 9 are driven by the active bevel gear 10; Two driven bevel gear rings are installed on the crushing cylinder 9 and the grinding cylinder 8. Both driven bevel gear rings are connected to the driving bevel gear 10. The two driven bevel gear rings are respectively arranged on both sides of the driving bevel gear 10. The bottom of the crushing cylinder 8 and the turning cylinder 3 are both threadedly mounted with plugs 27. Both plugs 27 can be used to feed the cheese to be crushed. The plug 27 at the bottom of the crushing cylinder 8 is used for the final discharge of the crushed material. In the discharge state, the crushing cylinder 8 is set vertically downward. The motor 1 is equipped with an encoder, which is data-connected to the PLC controller 24. The encoder is set to accurately control the turning angle of the turning drum 3. When the motor 1 is powered off, a self-locking structure is provided on its output shaft. The driven bevel gear rings on both sides of the driving bevel gear 10 drive the crushing drum 8 and the pulverizing drum 9 to rotate in opposite directions, forming a continuous processing flow of first crushing and then crushing. The rotary hammers 12 in the crushing drum 8 first crush the large block of frozen cheese into particles with a diameter of 5-10mm, and then transfer them to the pulverizing drum 9 for crushing through the turning drum 3. This two-way drive design improves the processing efficiency compared to the single-drum crushing method. At the same time, the material plug 27 at the bottom of the crushing drum 8 can quickly discharge the crushed material when it is in the vertical downward state. A set of elastic pressure members 11 are installed between the rolling frame 2 and the crushing frame 7; A set of T-shaped guide rods are installed on the rolling frame 2, each of which is slidably connected to the crushing frame 7, and a pressure spring is sleeved on the T-shaped guide rod corresponding to the position between the rolling frame 2 and the crushing frame 7; A rotary milling hammer 12 is rotatably mounted on the rolling frame 2, and a crushing shaft 13 is rotatably mounted on the crushing frame 7. Both the rotary milling hammer 12 and the crushing shaft 13 are driven by the hollow shaft 6. A through slot with two ends open is fixedly provided inside the hollow shaft 6. The rotary hammer 12 and the crushing shaft 13 are both equipped with coupling sections that are slidably connected to the through slot. The cross sections of the two coupling ends and the through slot are both regular hexagons. The regular hexagonal cross-section design of the through-groove of the hollow shaft 6 and the coupling section of the rotary hammer 12 and the crushing shaft 13 not only ensures high torque resistance for power transmission, but also allows the rotary hammer 12 and the crushing shaft 13 to move freely in the axial direction through the sliding connection. This connection mode of fixed rotation direction and free axial sliding enables the rotary hammer 12 to adaptively adjust the contact pressure with the material along with the elastic pressure member 11 of the crushing frame 2, and the crushing shaft 13 can synchronously follow the displacement changes of the crushing frame 7, ensuring the consistency of the crushing action of the knife ring 14 in different positions; The crushing shaft 13 is slidably connected to a plurality of knife rings 14 distributed along its axis; The crushing shaft 13 is provided with four guide grooves distributed in a circumferential array and slidably connected to the knife ring 14, and the corrugated baffle 16 is installed on the guide grooves; A follower spring 15 and a set of corrugated baffles 16 are connected between each pair of knife rings 14 and between the two outermost knife rings 14 and the crushing shaft 13. Four crushing knives 17 are rotatably mounted on each knife ring 14. Four racks 18 are fixedly mounted on the inner side of the crushing shaft 13. The bottom end of each crushing knife 17 is provided with a driven gear 19. Each driven gear 19 is transmission-connected to a rack 18 at the corresponding position. A knife distance adjustment system for cyclically changing the distance between the two knife rings 14 is provided on the inner side of the crushing shaft 13.

[0027] The knife distance adjustment system includes a fixed frame 35 installed on the flip cylinder 3 and a guide seat 36 rotatably connected to the crushing shaft 13. The crushing cylinder 9 is rotatably connected to the fixed frame 35. A reciprocating screw 37 is rotatably installed on the inner wall of the guide seat 36. A limiting guide rod 46 is installed on the fixed frame 35. A knife adjusting seat 38 is transmission-installed on the reciprocating screw 37. The knife adjusting seat 38 and the guide seat 36 are both slidably connected to the limiting guide rod 46. The knife adjusting seat 38 is rotatably connected to a knife ring 14 closest to the hollow shaft 6. A reciprocating rotating component that drives the reciprocating screw 37 to rotate periodically is provided on the fixed frame 35.

[0028] The reciprocating rotating assembly includes a differential shaft 39 and a reciprocating shaft 40 rotatably connected to the fixed frame 35. Differential gears 41 are installed on the differential shaft 39 and the grinding cylinder 9. The two differential gears 41 are meshed with each other. A half-tooth gear 42 is installed on the differential shaft 39, and a reciprocating gear 43 meshing with the half-tooth gear 42 is installed on the reciprocating shaft 40. A reversing torsion spring 44 is fixedly provided at the rotating connection between the reciprocating shaft 40 and the fixed frame 35. A square groove with an open tail end is fixedly opened inside the reciprocating screw 37. The square groove is slidably connected to the reciprocating shaft 40. The cross-sections of the square groove and the reciprocating shaft 40 are both regular hexagons.

[0029] In the reciprocating rotating assembly, when the half-tooth gear 42 is engaged with the reciprocating gear 43, the reciprocating shaft 40 is driven to rotate in the forward direction. When the half-tooth gear 42 is disengaged from the reciprocating gear 43, the reversing torsion spring 44 drives the reciprocating shaft 40 to reset in the reverse direction, thereby realizing the periodic reciprocating rotation of the reciprocating screw 37. The reciprocating change in the spacing between the knife rings 14 causes the range and force of the crushing knives 17 on different knife rings 14 to change during the crushing process. When the spacing between the knife rings 14 increases, the gaps between the crushing knives 17 become larger, which can accommodate more large particles of material. When the distance between the knife rings 14 decreases, the gap between the crushing knives 17 becomes smaller, the squeezing and shearing effect on the material is enhanced, and larger particles can be further crushed into smaller particles. This reciprocating change in the distance between the knife rings 14 can make the material receive a more comprehensive and uniform crushing effect in the crushing chamber, avoiding the situation where some materials are crushed too finely while others are not crushed sufficiently, thereby improving the uniformity of the crushed product; During the crushing process, materials may accumulate between the knife rings 14 for various reasons, causing the crushing device to be blocked. The reciprocating change in the spacing between the knife rings 14 causes the size of the gap between the knife rings 14 to change continuously. When the gap increases, the accumulated materials are likely to fall off. When the gap is reduced, the squeezing effect on the accumulated materials is enhanced, and they can be further crushed and discharged. This change can effectively prevent the accumulation and blockage of materials between the knife rings 14, ensure the normal operation of the crushing device, and improve the working efficiency and reliability of the equipment; Different types of frozen cheese have different hardness and viscosity. The reciprocating change of the distance between the knife rings 14 can automatically adjust the crushing force and range of action according to the characteristics of the material. For materials with higher hardness, when the distance between the knife rings 14 is smaller, the crushing knife 17 has a stronger shearing and squeezing effect on the material, which can crush the material more effectively. For materials with high viscosity, the reciprocating change in the spacing between the knife rings 14 can reduce the adhesion of the materials on the knife rings 14, avoiding the impact of material adhesion on the crushing effect. This adaptability enables the crushing device to process a variety of frozen cheeses with different characteristics, expanding the application range of the equipment; The reciprocating change of the distance between the knife rings 14 enables the crushing device to realize multi-stage crushing of the material in the same crushing process. When the distance between the knife rings 14 is large, the material can be initially crushed and pre-processed. When the distance between the knife rings 14 is small, the material can be finely crushed. This multi-stage crushing process can fully utilize the energy of the crushing device, reduce energy waste, and thus improve crushing efficiency. At the same time, since it avoids material blockage and improves crushing uniformity, it also further improves the overall working efficiency of the equipment. Four racks 18 are fixedly mounted on the inner side of the crushing shaft 13. A driven gear 19 is provided at the bottom end of each crushing blade 17. Each driven gear 19 is transmission-connected to a rack 18 at a corresponding position. When the crushing shaft 13 rotates, the racks 18 are driven to rotate together. Since the driven gears 19 are meshed with the racks 18, the driven gears 19 are driven by the racks 18 to rotate, thereby driving the crushing blades 17 to rotate around their rotation axis, thereby changing the angle of the crushing blades 17. The cyclic change of the angle of the crushing knife 17 causes the cutting angle of the crushing knife 17 to continuously change when crushing the material. Different cutting angles have different effects on the material. When the crushing blade 17 cuts into the material at a larger angle, the shearing effect on the material is stronger, which is suitable for crushing larger particles; When the crushing blade 17 cuts into the material at a smaller angle, the crushing and grinding effect on the material is stronger, which is suitable for further refining the particles. This cyclic change in angle enables the crushing blade 17 to have different effects on the material at different stages, thereby more effectively crushing the material and improving the crushing effect; When the crushing blade 17 is always crushing at a fixed angle, then at a specific angle, the crushing blade 17 will be subjected to greater impact and friction, resulting in severe local wear. However, the cyclic change of the angle of the crushing blade 17 ensures that the crushing blade 17 is evenly worn at all angles during operation, avoiding local excessive wear. This can extend the service life of the crushing blade 17 and reduce the maintenance cost of the equipment. Different materials have different requirements for the angle of the crushing knife 17 during the crushing process; For harder materials, a larger cutting angle is required for crushing; For softer materials, a smaller cutting angle is more suitable. The cyclic change of the angle of the crushing knife 17 enables the crushing device to automatically adapt to the characteristics of different materials during the crushing process, without the need for manual adjustment of the angle of the crushing knife 17, thereby improving the intelligence of the equipment and the material adaptability. By cyclically changing the angle of the crushing blade 17, the crushing device can realize multiple crushing functions on the same equipment, performing coarse crushing when the angle is large and fine crushing when the angle is small. This versatility enables the crushing device to meet different production needs and improve the utilization rate and production efficiency of the equipment.

The crushing shaft 13 cyclically changes the angle of the crushing knife 17 through the rack 18 and the driven gear 19 mechanism. The displacement of the crushing frame 7 drives the crushing shaft 13 to move axially. The crushing drum 9 rotates through the differential gear 41, the half-tooth gear 42 and the reciprocating gear 43 intermittent mechanism and the reverse torsion spring 44, driving the reciprocating screw 37 to rotate periodically.
