Description

Technical Field

[0001] This invention relates to the field of material mixing and conveying technology, and more specifically, to a silicon powder feeding mechanism with stirring. Background Technology

[0002] In the processing scenarios of spreading silicon powder after mixing with other materials (such as composite material preparation and powder molding), existing technologies have long faced problems such as single spreading form, insufficient control precision, material residue and poor equipment stability, making it difficult to meet diverse process requirements. Specifically, the spreading function of traditional silicon powder feeding mechanisms is fixed, and most can only achieve simple flat spreading or disordered stacking. They cannot flexibly switch the spreading form according to production needs. For example, they cannot achieve spiral pushing of materials through structural design (to solve the problem of uneven mixing of deep materials), nor can they accurately control the flow state of the nozzle to achieve layered spreading (to meet the layered requirements of multi-layer composite materials for material distribution). This results in the equipment's adaptability being limited to a single process and poor versatility.

[0003] Meanwhile, existing devices lack a flexible and reliable mechanism for adjusting nozzle flow: either they rely on manual switching, which is inefficient and prone to operational errors; or they cannot dynamically adjust according to changes in material pressure within the conveying cylinder, often resulting in uneven nozzle output due to pressure fluctuations, or even material residue clogging the nozzle channel, causing not only raw material waste but also frequent shutdowns for cleaning, affecting production continuity. In addition, the coordination stability of the stirring and spreading components in traditional mechanisms is insufficient, and there is a lack of effective support and positioning structures during the spreading process. The spreading trajectory is easily deviated due to component shaking, making it difficult to ensure uniform distribution of material in the spreading area, ultimately affecting product molding quality and restricting the efficiency and reliability of the silicon powder feeding process. In view of this, we propose a silicon powder feeding mechanism with stirring. Summary of the Invention

[0004] The purpose of this invention is to provide a silicon powder feeding mechanism with stirring, so as to solve the technical problem that existing silicon powder feeding mechanisms are difficult to flexibly switch the material spreading form.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a silicon powder feeding mechanism with stirring, comprising a base, a feeding tank arranged on top of the base, a spreading and mixing mechanism arranged inside the feeding tank, a feeding component and a stabilizing component arranged above the feeding tank, wherein the spreading and mixing mechanism includes a transmission rod capable of rotating clockwise or counterclockwise, a fixed or movable stirring rod sleeved on the surface of the transmission rod, a balance ring rotatably sleeved on the surface of the transmission rod, and a plurality of straight cylinders fixedly connected in a ring array on the surface of the balance ring, each of the straight cylinders having internal passages... The partition divides the passage into several flow channels. Each flow channel has several inclined plates with electric sliders slidingly fitted on both sides of its inner wall. One of the inclined plates has a notch on its surface. Each straight cylinder has a conveying cylinder fixedly fitted inside. The conveying cylinder has a receiving nozzle that is slidably sealed inside a hole on its surface. Each receiving nozzle has a hollow sphere that is rotatably sealed on both sides of its inner wall by a rod. The hollow sphere has a nozzle with a counterweight that is rotatably sealed inside its interior, and the bottom of the nozzle is engaged with the notch. The hollow sphere rolls downward when pressure is applied and rolls upward when pressure decreases.

[0006] During powder spreading, several nozzles flow through the material, while several conveyor cylinders move circumferentially around a balance ring, allowing the material to be spread in a spiral manner. A non-flowing nozzle is spaced between any two adjacent flowing nozzles, and the conveyor cylinders move circumferentially around the balance ring, allowing the material to be spread in a layered manner. This invention, through the ingenious design of the powder spreading and mixing mechanism, achieves flexible switching and precise control of the silicon powder mixture spreading pattern, combining the advantages of high-efficiency spreading and residue prevention. On one hand, the transmission rod can drive the conveyor cylinders to move circumferentially around the balance ring, and the nozzles with counterweights ensure the material is spread smoothly. The material flows out in a directional manner, enabling spiral propulsion and material spreading through all nozzles, and also allowing for layered spreading through a layout of "one non-flowing nozzle between adjacent flowing nozzles," adapting to the material spreading requirements of different processes. On the other hand, the hollow sphere can roll up and down with changes in material pressure inside the conveying cylinder. Combined with the snap-fit ​​adaptation between the inclined plate notch and the nozzle, the flow state of the nozzle can be flexibly adjusted. At the same time, the cooperation structure between the transmission rod and the balance ring provides stable support for material spreading, effectively improving the accuracy and uniformity of material spreading, and ensuring the efficiency and reliability of the silicon powder feeding process.

Each material distribution plate has a protrusion that engages with a vibrating plate, and the vibrating plate is in movable contact with the striking block.

[0013] Preferably, the stabilizing component includes a plurality of electric push rods, which are fixedly connected to the upper surface of the top cover in a circular array.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This invention, through the ingenious design of the material spreading and mixing mechanism, achieves flexible switching and precise control of the silicon powder mixture spreading pattern, combining the advantages of high-efficiency spreading and residue prevention. On the one hand, the transmission rod can drive the conveying cylinder to move circumferentially around the balance ring as the axis, and the nozzle with counterweight ensures the directional flow of materials. It can achieve spiral pushing spreading through the flow of all nozzles, and can also achieve layered spreading through the layout of "adjacent flowing nozzles separated by a non-flowing nozzle", adapting to the spreading pattern requirements of different processes. On the other hand, the hollow sphere can roll up and down with the pressure change of the material in the conveying cylinder. Combined with the snap-fit ​​adaptation of the inclined plate notch and the nozzle, it can flexibly adjust the nozzle flow state. At the same time, the cooperation structure of the transmission rod and the balance ring provides stable support for spreading, effectively improving the spreading accuracy and uniformity, and ensuring the high efficiency and reliability of the silicon powder feeding process.

[0018] 2. This invention effectively solves the problems of material residue and uneven supply through the dynamic adjustment and vibration design of the distribution plate. When the circumferential motion of the conveyor cylinder drives the rigid tube to move, the distribution plate rotates with the circular plate to form a spiral feeding space. The vibration generated by the collision of the vibrating plate and the striking block can shake the residual material on the surface of the distribution plate into the rigid tube, ensuring sufficient material conveying. When cleaning residue, the rotation of the movable ring can push the material on the surface of the distribution plate into the rigid tube, avoiding material waste and accumulation. This design not only achieves continuous stability in the feeding process, but also reduces the impact of material residue on subsequent processes, improving the continuity and reliability of the overall feeding process.

[0019] 3. This invention provides a reliable guarantee for the operation of the servo motor and the relative fixation of the feeding tank and top cover through multi-structure collaborative limiting. During material spreading, the push plate pushes the sliding block to move the corresponding locking pin, allowing the rigid tube to push open the square pin to pass through. The remaining square pins are fixed by the locking pins, preventing the servo motor from shifting due to reaction force. During stirring, the electric push rod pushes the limiting push rod to rotate the insert, fixing the square pin with the locking cylinder. At the same time, the sliding block moves down to provide space for the locking cylinder to rotate, ensuring the relative stability of the feeding tank and top cover. This dynamic and static combined stability design does not affect the normal movement of components such as rigid tubes, and can provide stable support for the equipment under different working conditions, avoiding material spreading deviations or equipment failures caused by component shaking, and improving the safety and stability of equipment operation.

[0042] like Figures 1-12 As shown, the present invention relates to a silicon powder feeding mechanism with stirring, comprising a base 1, a feeding system 11 arranged on the top of the base 1, a feeding tank 2 arranged on the top of the base 1, a top cover 21 arranged above the feeding tank 2, an annular plate 22 that is rotatably fitted between the feeding tank 2 and the top cover 21, a spreading and mixing mechanism 3 arranged inside the feeding tank 2, a feeding assembly 4 arranged above the feeding tank 2, and a stabilizing assembly 5.

[0043] It is worth noting that the feeding system 11 is a conventional technology and will not be described in detail here. It has a conveying structure and can convey liquid and solid mixtures for mixing with silicon powder.

[0044] Two push plates 221 are fixedly connected in a ring array on the upper surface of the ring plate 22.

[0045] The material mixing mechanism 3 includes a servo motor 31, which is fixedly arranged on the upper surface of the top cover 21. The output shaft of the servo motor 31 passes through the top cover 21. A transmission rod 32 is fixedly connected to the output shaft of the servo motor 31, and the bottom of the transmission rod 32 is rotatably connected to the inner wall of the bottom of the feeding tank 2. A pawl 321 is arranged inside the transmission rod 32. Two slots 322 are formed in a ring array on the surface of the transmission rod 32. A stirring rod 33 with blades is rotatably sleeved on the surface of the transmission rod 32. A ratchet 331 is fixedly arranged inside the stirring rod 33, and the ratchet 331 meshes with the pawl 321. A balance ring 34 is rotatably sleeved on the surface of the moving rod 32. The balance ring 34 is fixedly connected to the annular plate 22 by a plug rod. The inner wall of the balance ring 34 has a first spring piece 341 fixedly arranged in a ring array. A locking block 342 is slidably fitted in a hole on the inner wall of the balance ring 34, and the locking block 342 is elastically fitted with the first spring piece 341. The locking block 342 is also fitted with the locking groove 322. Two straight cylinders 35 are fixedly connected in a ring array on the surface of the balance ring 34. The interior of each straight cylinder 35 is divided into several flow channels by a partition 351. Several electric sliders are slidably fitted on the inner walls of both sides of each flow channel. An inclined plate 36, one of which has a notch 361 on its surface, is fitted with a conveying cylinder 37 inside each straight cylinder 35. An auger blade 371 is rotatably arranged inside each conveying cylinder 37 via a rod, with the rod end of the auger blade 371 passing through the conveying cylinder 37. A helical gear 38 is fixedly connected to the rod end of the auger blade 371. A helical gear ring 39 is fixedly arranged on the inner wall of the feeding tank 2, and the helical gear 38 meshes with the helical gear ring 39. A receiving nozzle 310 is fitted with a sliding seal inside a hole on the surface of the conveying cylinder 37. A scraper 3101 is arranged inside the receiving nozzle 310. Each receiving nozzle... The inner walls on both sides of the nozzle 310 are sealed with hollow spheres 311 by insert rods. The hollow spheres 311 are rotated and sealed with nozzles 312 with counterweights. The bottom of nozzles 312 is engaged with notches 361. Each hollow sphere 311 has a first gear 313 fixedly connected to both ends of the insert rod. Each partition 351 has a gear rack 314 arranged in the hole, and the gear rack 314 meshes with the first gear 313. Each hollow sphere 311 has a first tension spring 315 arranged at both ends of the insert rod through a sheath, and the end of the first tension spring 315 is fixedly connected to the surface of the conveying cylinder 37.

[0046] It is worth noting that the transmission rod 32 rotates clockwise or counterclockwise, causing the locking block 342 to lock or slide against the locking groove 322. During the sliding process, the locking block 342 will vibrate when it collides with the transmission rod 32 under the elastic action of the first spring plate 341. When the material is stopped, the material residue caused by the extrusion pressure in the conveying cylinder 37 can be shaken out or loosened.

[0047] It is worth noting that when the inclined plates 36 are unfolded, the inner wall of the flow channel is inclined to transport materials such as silicon powder; when they converge, the notch 361 on the inclined plate 36 abuts against the bottom of the nozzle 312, so that the hollow ball 311 cannot roll and the nozzle 312 does not flow, thus realizing the function of adjusting the flow state of each nozzle 312.

[0048] It is worth noting that by providing a scraper 3101 inside the receiving nozzle 310, when the hollow ball 311 rolls, some of the mixture remains on the surface of the hollow ball 311. Through the rolling of the hollow ball 311 and the cutting surface of the scraper 3101 adhering to the surface of the hollow ball 311, the residual powder can be removed, thus avoiding affecting the sealing rolling fit between the hollow ball 311 and the receiving nozzle 310.

[0049] Specifically, the servo motor 31 drives the transmission rod 32 to rotate clockwise or counterclockwise. When rotating clockwise, the locking block 342 engages with the locking slot 322, causing several conveying cylinders 37 to move circumferentially around the balance ring 34. Through the meshing transmission of the helical gear 38 and the helical gear ring 39, the material is fed into the conveying cylinder 37. The material is continuously conveyed by the auger blades 371, which increases the internal pressure and pushes the receiving nozzle 310 and the hollow ball 311 downward. Then, through the meshing transmission of the gear rack 314 and the first gear 313, the hollow ball 311 rolls. The nozzle 312 is made to output vertically downward by the counterweight, so that the holes on the surface of the hollow ball 311, the receiving nozzle 310 and the nozzle 312 are connected, and the mixture flows out from inside. Through the upward movement of several inclined plates 36, the notch 361 abuts against the bottom of some nozzles 312, preventing flow. The material is then spread in layers through other flowing nozzles 312.

[0050] This invention achieves precise spreading and efficient mixing of silicon powder mixtures through the multi-component collaborative design of the spreading and mixing mechanism 3. On one hand, when the servo motor 31 drives the transmission rod 32 to rotate, the circumferential motion of the conveying cylinder 37 can be controlled by the engagement or sliding of the locking block 342 and the locking groove 322. In conjunction with the meshing of the helical gear 38 and the helical gear ring 39, the auger blade 371 is driven to feed the material. Then, the hollow ball 311 rolls and the counterweight of the nozzle 312 is oriented to ensure that the material flows vertically downward. On the other hand, the flow state of the nozzle 312 is adjusted by the expansion or convergence of the inclined plate 36. This allows the circumferential motion of the flow nozzle 312 to achieve spiral pushing and spreading of the material, and also allows the partial blocking of the nozzle 312 to achieve layered spreading. At the same time, the vibration generated by the collision between the locking block 342 and the first spring 341 when the transmission rod 32 slides can shake out the residual material in the conveying cylinder 37, avoid blockage, meet the requirements of different processes for the spreading shape of the material, and improve the spreading accuracy and material utilization rate.

[0051] like Figures 3-4 and Figures 11-15As shown, the feeding assembly 4 includes several supports 41, which are arranged in a ring array on the upper surface of the base 1. The top of the supports 41 is fixedly connected to a distributing cylinder 42. A circular plate 43 is rotatably connected inside the distributing cylinder 42. Two rigid tubes 44 are fixedly connected to the bottom of the circular plate 43 and are connected to the conveying cylinder 37. A movable ring 45 with a pneumatic slider is rotatably connected to the top of the distributing cylinder 42. A cover plate 46 is rotatably connected inside the movable ring 45 and is connected to the output end of the feeding system 11. Several distributing plates 47 are movably sleeved inside the movable ring 45. One end of the distributing plate 47 is fixedly connected to the circular plate 43, and the other end of the distributing plate 47 is fixedly connected to the movable ring 45. Each distributing plate 47 has a waist-shaped groove 48 on its upper surface. Several striking blocks 481 are arranged on the inner walls of both sides of the waist-shaped groove 48. A vibrating plate 49 is engaged with a protrusion on each distributing plate 47 and is in contact with the striking block 481.

[0052] Specifically, when the conveyor cylinder 37 is spreading material, the rigid tube 44 moves circumferentially. At this time, several material distribution plates 47 rotate in sequence, making their internal flow space spiral. The contact between the vibrating plate 49 and the striking block 481 generates vibration, which vibrates some of the material in the spiral space to the input end of the rigid tube 44. When cleaning the residual material, the rotating movable ring 45 pushes the material on the surface of several material distribution plates 47 into the interior of the rigid tube 44.

[0053] This invention effectively solves the problems of material residue and uneven supply by dynamically adjusting and vibrating the distribution plate 47. When the conveying cylinder 37 moves in a circular motion, driving the rigid tube 44 to move, the distribution plate 47 rotates with the circular plate 43 to form a spiral feeding space. The vibration generated by the collision between the vibrating plate 49 and the striking block 481 can vibrate the residual material on the surface of the distribution plate 47 into the rigid tube 44, ensuring sufficient material conveying. When cleaning residue, the rotation of the movable ring 45 can push the material on the surface of the distribution plate 47 into the rigid tube 44, avoiding material waste and accumulation. This design not only achieves continuous stability in the feeding process, but also reduces the impact of material residue on subsequent processes, improving the continuity and reliability of the overall feeding process.

[0054] like Figure 4 and Figures 16-21As shown, the stabilizing component 5 includes several electric push rods 51, which are fixedly connected to the upper surface of the top cover 21 in a circular array. Several driving blocks 52 are fixedly connected to the upper surface of the top cover 21 in a circular array. Each driving block 52 has several spiral grooves 521 arranged in a circular array on its inner wall. Each driving block 52 is rotatably adapted to a limiting push rod 53 with a spiral block, and the spiral block on the limiting push rod 53 matches the spiral groove 521. Furthermore, the limiting push rod 53 is rotatably connected to the electric push rod 51. At the output end of the push rod 51, each drive block 52 has a rotatably connected insert 54 inside, and a limiting push rod 53 is inserted into the insert 54. A square pin 55 is hinged to the end of the insert 54. Two second tension springs 56 are fixedly connected to one side of each drive block 52, and the second tension springs 56 are fixedly connected to the square pins 55. Several locking blocks 57 are fixedly connected to the upper surface of the feeding tank 2. An arc-shaped groove 571 is opened on one side of the inner wall of the locking block 57. Each locking block 57 has a rotatably connected movable push rod inside. The engaging cylinder 58 has an arc-shaped groove 571 that matches the movable groove on the engaging cylinder 58. The square pin 55 is also engaged inside the engaging cylinder 58. A semi-circular hole 581 is provided on one side of the engaging cylinder 58, and this semi-circular hole 581 combines with the groove on the square pin 55 to form a circular hole. Each engaging block 57 has a movable groove 59 at its bottom. A drum 510 is fixedly connected to the inner walls of both sides of each movable groove 59. Several first springs 5 ​​are fixedly connected to the inner walls of each drum 510 in a linear array. 11. Each drum 510 has a sliding top plate 512 inside, and the top plate 512 is elastically adapted to the first spring 511. A sliding block 513 is sleeved on the surface of the drum 510, and the push plate 221 is in movable contact with the sliding block 513. A second spring 514 is fixedly connected to one side of the sliding block 513, and the second spring 514 is fixedly connected to the locking block 57. A locking pin 515 is slidingly adapted inside the semi-circular hole 581, and the protrusion on the locking pin 515 is inserted into the groove on the sliding block 513.

[0055] It is worth noting that the insert 54 is provided with a limiting groove inside, and the limiting push rod 53 is provided with a limiting slider on its surface and slides and adapts to the limiting groove, so that the limiting push rod 53 slides through the spiral block at its end, causing the insert 54 to rotate, which is used to adjust the hinge direction.

[0056] It is worth noting that the square pin 55 hinged at the end of the insert 54 is an existing one-way rotation limit hinge. The square pin 55 can only rotate in one direction. This is used to ensure that the rigid tube 44 can move in a circular motion while the feeding tank 2 is fixed to the top cover 21 and the servo motor 31 is stable when it is working, as well as the stability of the servo motor 31 when the conveying cylinder 37 stops feeding material.

[0057] It is worth noting that when the insert 54 rotates, it drives the locking cylinder 58 to rotate via the square pin 55. The locking cylinder 58, in turn, drives the locking pin 515 to rotate. When the locking cylinder 58 rotates, its surface comes into contact with the sliding block 513, applying pressure. This causes the sliding block 513 to move downwards and out of the rotation space of the locking cylinder 58. At this time, the sliding block 513 applies pressure to the top plate 512 and moves downwards, allowing the locking cylinder 58 to rotate smoothly and preventing interference between the locking cylinder 58 and the sliding block 513. Simultaneously, the locking pin 515 is inserted into... Inside the circular hole, the square pin 55 is fixed relative to the locking cylinder 58. When the rigid tube 44 moves circumferentially, the push plate 221 pushes the locking pin 515 out of the circular hole, allowing the square pin 55 to rotate axially and the rigid tube 44 to move smoothly. The remaining locking pins 515 that are not pushed by the push plate 221 are still inserted inside the circular hole. The square pin 55 is fixed to the locking cylinder 58, which fixes the feeding tank 2 to the top cover 21, preventing the servo motor 31 from moving due to the reaction force when it is working, thus affecting the material spreading process.

[0058] Specifically, during material laying, the rigid tube 44 and the annular plate 22 move in a circular motion between the feeding tank 2 and the top cover 21. When the rigid tube 44 passes the square pin 55, the push plate 221 applies a force to the sliding block 513. The sliding block 513 drives the locking pin 515 to move, causing it to move out of the circular hole. The square pin 55 can be hinged and rotated, and the rigid tube 44 pushes open the square pin 55 and moves out. When the rigid tube 44 passes one of the square pins 55, the remaining square pins 55 are inserted into the circular hole by the locking pins 515, so that the square pins 55 are fixed to the locking cylinder 58, providing a stable ring for the servo motor 31. To prevent the square pin 55 from moving out of the locking cylinder 58 due to reaction force, thus affecting the stability of the servo motor 31; during stirring, the rigid tube 44 and the annular plate 22 do not move. At this time, the electric push rod 51 pushes the limiting push rod 53, causing the spiral block on the limiting push rod 53 to slide inside the spiral groove 521. The insert cylinder 54 rotates, and the square pin 55 drives the locking cylinder 58 to rotate. At this time, the surface of the locking cylinder 58 contacts the upper surface of the sliding block 513, causing the sliding block 513 to move downward. The top plate 512 moves downward under pressure and matches the drum 510, thereby fixing the feeding tank 2 and the top cover 21 relatively.

[0059] This invention provides a reliable guarantee for the operation of the servo motor 31 and the relative fixation of the feeding tank 2 and the top cover 21 through multi-structure collaborative limiting. During material spreading, the push plate 221 pushes the sliding block 513 to move the corresponding locking pin out, allowing the rigid tube 44 to push open the square pin 55 to pass through. The remaining square pins 55 are fixed by the locking pins, preventing the servo motor 31 from shifting due to reaction force. During stirring, the electric push rod 51 pushes the limiting push rod 53 to drive the insert 54 to rotate, fixing the square pin 55 with the locking cylinder 58. At the same time, the sliding block 513 moves down to provide space for the locking cylinder 58 to rotate, ensuring the relative stability of the feeding tank 2 and the top cover 21. This dynamic and static combined stability design does not affect the normal movement of components such as the rigid tube 44, and can provide stable support for the equipment under different working conditions, avoiding material spreading deviations or equipment failures caused by component shaking, and improving the safety and stability of equipment operation.

[0060] Working Principle: This embodiment provides a silicon powder feeding mechanism with stirring, for material spreading and conveying: First, the feeding system 11 is activated by an external control system, feeding the material into the distribution cylinder 42 through a pipe. Some material flows from the rigid pipe 44 into the conveying cylinder 37. At this time, the servo motor 31 drives the transmission rod 32 to rotate through the circuit system. The non-meshing sliding connection between the pawl 321 and the ratchet 331 causes the transmission rod 32 to rotate. The stirring rod 33 does not rotate due to the weight of the blade and the friction with the material. It is then locked in the slot 322 by the clamping block 342, driving several conveying cylinders 37 to move circumferentially around the balance ring 34. Through the meshing transmission of the helical gear 38 and the helical tooth ring 39, the material is conveyed into the conveying cylinder 37. At this time, after... The conveying of the auger blades 371 increases the internal material accumulation pressure, which pushes the receiving nozzle 310 and the hollow ball 311 downward. The hollow ball 311 is driven by the meshing of the gear rack 314 and the first gear 313, causing it to rotate until the flow hole connects with the receiving nozzle 310. The nozzle 312 is made to output vertically downward through the counterweight, and the material flows out from the nozzle 312. At this time, the external control system causes several inclined plates 36 to unfold, and several nozzles 312 to flow and make circular motion, so that the material can be spirally pushed and spread. When some of the inclined plates 36 move upward and gather, the notch 361 contacts the end of the nozzle 312 and applies force, so that the hollow ball 311 cannot move downward and rotate, causing some nozzles 312 to flow, which can spread the material in layers.

[0061] Material feeding during spreading: During powder spreading, the rigid tube 44 moves circumferentially, causing the circular plate 43 to rotate inside the distribution cylinder 42. The circular plate 43 drives the distribution plate 47 to rotate, and two adjacent distribution plates 47 slide in the waist-shaped groove 48 through the vibrating plate 49, causing several distribution plates 47 to rotate to form a spiral feeding space. When the vibrating plate 49 slides in the waist-shaped groove 48, the vibrating plate 49 collides with the striking block 481 to generate vibration, which shakes the excess material on the surface of several distribution plates 47 in a stepped shape into the rigid tube 44, and then flows into the conveying cylinder 37.

[0062] Stability of the driving components: During material laying, the annular plate 22 and the rigid tube 44 move in a circular motion. When the rigid tube 44 is about to contact the square pin 55, the push plate 221 applies a pushing force to the sliding block 513. The sliding block 513 drives the locking pin 515 to move, causing it to move out of the circular hole formed by the semi-circular hole 581 and the slot on the square pin 55. This allows the square pin 55 to rotate axially, and the rigid tube 44 pushes open the square pin 55 and moves out. When the rigid tube 44 passes one of the square pins 55, the remaining square pins 55 are inserted into the circular hole by the locking pin 515, fixing the square pins 55 to the locking sleeve 58 and providing a stable environment for the servo motor 31. After the rigid tube 44 pushes open the square pin 55 and moves out, the second spring 514 applies a force to the sliding block 513. The sliding block 513 drives the locking pin 515 to move into the circular hole, so that the square pin 55 is fixed with the locking cylinder 58 again. During stirring, the stirring rod 33 is rotated by the meshing transmission of the pawl 321 and the ratchet 331 to stir the mixture. At the same time, the electric push rod 51 pushes the limit push rod 53 through the external control system. The spiral block on the limit push rod 53 slides in the spiral groove 521, the cylinder 54 rotates, and then the square pin 55 drives the locking cylinder 58 to rotate, so that the square pin 55 is relatively fixed with the locking cylinder 58, and the surface of the locking cylinder 58 contacts the upper surface of the sliding block 513, so that the sliding block 513 moves downward, the top plate 512 moves downward under pressure, and matches the drum 510, thereby fixing the feeding tank 2 and the top cover 21 relatively, providing a stable working environment.
