Description

Technical Field

[0001] The present invention discloses a mesh fabric preparation device, in particular to a food raw material mixing device and its mixing process. Background Art

[0002] During the food processing and production process, a variety of ingredients need to be added. After adding a variety of ingredients, they need to be fully stirred so that different materials are mixed with each other to reach a uniform and suitable state. Therefore, the mixing device is an important step in the production process. At the same time, according to different products, the mixing devices will also be different. Some need to be dissolved, heated and decomposed during the mixing process, and even crushed.

[0003] However, in any case, the mixing device generally has stirring and spiral mechanisms. During continuous rotation, different substances are fully mixed to reach the required state. And the stirring devices are generally arc-shaped or spiral, with a moving arc. Thus, during the stirring process, it is easy to make the materials move back and forth to better mix fully. If it is pushed in a vertical plane, although the materials can be mixed, the mixing degree of the materials is relatively slow. Therefore, arc-shaped or irregular states are mostly used. And the food materials are generally sticky after stirring. Thus, the stirring parts are easy to adhere to the materials. However, after stirring and mixing, when discharging the materials, due to the large area of the stirring parts, there may be more food materials adhered after rotation and adhesion. And in the prior art, food processing is generally sealed to reduce the entry of impurities. Therefore, if it is not observed or opened for cleaning in time, it is easy to cause the adhered materials to solidify and cannot be used continuously, resulting in waste. But because of the arc shape or irregularity, it is not convenient to clean. And in the prior art, it is generally disassembled, so it is inconvenient. This application proposes another solution, which automatically cleans after the work stops, reduces material residue and increases the discharge rate. Summary of the Invention

[0009] Preferably, the elastic sheet cannot completely pass through the limiting member one, and a limiting member two for squeezing the elastic sheet to reset and fit on the rotating member is provided on the rotating member.

[0010] Preferably, a stirring rod is rotatably connected outside the rotating member, and the stirring rod is located in the middle of the spiral of the stirring member, a clamping groove for accommodating the stirring rod to be embedded is provided on the rotating member, a fixing block for supporting and blocking the stirring rod from moving down is provided at the bottom of the clamping groove, a connecting rod connected to the stirring rod is slidably connected to the clamping groove, a sleeve is provided at one end of the connecting rod away from the clamping groove, the sleeve is sleeved on the stirring rod, and the sleeve is rotatably connected to the connecting rod.

[0011] Preferably, a rolling member is provided at one end of the connecting rod in the card slot. A connecting rope is provided on the rolling member, and the other end of the connecting rope extends to be connected to the upper end of the rotating rod. A guiding groove for accommodating the sliding of the rolling member and guiding the movement of the rolling member is provided inside the card slot.

[0012] Preferably, a second gear is clamped at the middle of the rolling member. A second rack that abuts against the second gear is provided at the upper end of the guiding groove. A winding roller for accommodating the winding of the connecting rope is provided on the rotating member, and the winding roller is rotatably connected to the rotating member. Both ends of the connecting rope extend from the front and rear ends of the winding roller and are respectively connected to the rolling member and the rotating rod.

[0013] Preferably, a roller for accommodating the movement of the connecting rope is provided between the winding roller and the rotating rod. The connecting rope between the roller and the winding roller is a buffer section, and the buffer section is in a relaxed state. The length of the buffer section is set according to the distance that the cleaning member moves to the lower end of the stirring rod.

[0014] Preferably, a first spring for pushing the winding roller to reset is provided inside the winding roller. A second spring is provided between the stirring rod and the rotating member. The elastic forces of the first spring and the second spring are greater than the force of the stirring rod colliding with and stirring the material, and the elastic forces of the first spring and the second spring are less than the force of the rotating rod moving downward.

[0015] A food raw material mixing process includes the following steps:

[0016] First, the materials to be processed and mixed are introduced into the machine body through the upper entrance of the machine body. The control program of the machine body is set in advance by the PLC to control the driving member, and the stirring member is driven to rotate, continuously stirring and mixing the materials. The stirring member and the stirring rod switch between forward and reverse rotation according to the stirring degree and time. When the materials in the machine body need to be heated, the switch of the heating wire inside the machine body can be turned on to heat the materials so that the materials can be stirred better. After repeated mixing to the required degree, the bottom of the machine body is opened to discharge the materials, and the mixing is completed.

[0017] Second, after stirring, the switch of the first cylinder outside the machine body is turned on. At the same time, the first cylinder moves downward and drives the rotating rod to move downward so that the convex block is separated from the groove. Thus, the bottom of the external thread of the rotating rod abuts against and is embedded in the upper end of the internal thread of the rotating member. The downward movement of the rotating rod drives the cleaning member to fit with the stirring member. In this way, the middle gap between the upper end of the stirring member and the cleaning member is opposite. Then, the driving member is turned on to rotate forward again, driving the stirring member to be embedded in the gap of the cleaning member. At the same time, after the rotating rod is driven by the rotating member to move downward, when the stirring member continues to rotate, it will continue to move along the gap of the cleaning member and drive the cleaning member to move downward.

[0018] Finally, after rotating to the bottom, switch one will be turned on, causing gear one to drive rack one to move. Rack one drives the push plate through the elastic sheet, scraping the residual materials along the surface of the cleaning part. At this time, turn on the switch outside the machine body to control the reverse rotation of the driving part, causing the cleaning part to reset and driving the reverse rotation switch of motor one, causing the elastic sheet to reset.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] First, after turning on cylinder one by using this device, push the rotating rod downward, causing the bump to disengage from the groove of the rotating rod. The cleaning part together with the blocking piece moves down to the chute, and the cleaning part fits with the stirring part. At this time, the internal thread of the rotating part abuts against the external thread of the rotating rod. Then, turn on the switch of the driving part controlled by the machine body again, causing the stirring part together with the rotating part to rotate. Through threaded connection, the rotating rod moves downward, and the cleaning part moves down along the upper and lower surfaces of the stirring part to the bottom of the stirring part. In this way, during the movement, the materials adhered to the surface of the stirring part are scraped off, achieving the effect of cleaning the stirring part. Secondly, the materials scraped off due to the self-weight on the lower surface of the stirring part will fall downward onto the upper surface of the next circle of the stirring part. When the cleaning part moves to the upper surface of the next circle of the stirring part, the scraped-off materials will be cleaned together.

[0021] Second, because the cleaning part is in brief contact with the materials, even if there is not much adhesion due to the short contact, and secondly, due to the oil film on the surface, the adhesion can be reduced. After moving to the end of the stirring part, turn on switch one to control the start of motor one, and drive gear one to rotate, pushing the engaged rack one to rotate. In this way, rack one pushes the connected elastic sheet outward, and the elastic sheet is squeezed straight by the restriction of limiting part one, and is pushed outward to drive the push plate to push off the materials adhered to the cleaning part. Because the adhesion due to the oil film is relatively loose, it is convenient to clean.

[0022] Third, after the rotating rod moves downward and compresses spring one, it will simultaneously drive the connecting rope to move downward. The connecting rope moves downward along the roller, and the buffer section of the connecting rope is straightened. After continuing to move downward, it will drive the winding roller to rotate. The connecting rope near the roller end is pulled outward, and the other end is wound, driving the rolling part to move upward. In this way, it is continuously wound and continuously moves upward, causing the rolling part to drive the connecting rod to move upward. When the connecting rod moves upward, it will drive the sleeve to move upward, pulling the stirring rod. One end of the stirring rod is rotatably connected to the rotating part and cannot move upward. In this state, the stirring rod rotates, and the kit moves upward along the stirring rod. In this state, when the kit moves along the stirring rod, the materials adhered to the stirring rod can also be cleaned. Description of the Drawings

Detailed implementation manners

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0033] A food raw material mixing device and its mixing process, such as Figures 1 - 8As shown in the figure, it includes a body 1. A rotating member 2 is rotatably connected inside the body 1. A stirring member 3 is clamped outside the rotating member 2. The stirring member 3 is arranged in a spiral shape. When this device is normally used, the body 1 is turned on, and the stirring member 3 rotates continuously. The spiral stirring member 3 continuously rotates the materials put into the body 1. After long-term repeated rotation, various materials are fully mixed, and then the mixed finished products are extruded. Moreover, under normal conditions, the surface of the stirring member 3 is also coated with an oil film to reduce the adhesion of the materials. However, under long-term use, the continuous stirring and friction cause the oil film to decrease, so adhesion will still occur.The rotating member 2 is provided with a chute 4 at the upper surface of the stirring member 3, and the chute 4 is arranged along the path of the stirring member 3. A sleeve 5 is provided at the upper end of the rotating member 2. A rotating rod 6 is slidably connected up and down inside the sleeve 5. External threads and internal threads are respectively provided on the outer circumference of the rotating rod 6 and the inner circumference of the rotating member 2. After the rotating rod 6 moves downward, the external threads are in contact and engaged with the internal threads of the rotating member 2. A cleaning member 7 is provided on the rotating rod 6 and passes through the rotating member 2 and moves along the chute 4. The cleaning member 7 extends outward to wrap the upper and lower surfaces of the stirring member 3. A blocking piece 8 for blocking the material from overflowing backward is provided on the cleaning member 7. A driving device is provided on the machine body 1. The driving device includes a driving member 9 located at the top of the machine body 1 and at the top of the rotating member 2 for driving the rotating member 2 to rotate. A groove 10 is provided on the rotating rod 6. A convex block 11 is provided on the sleeve 5 and is embedded in the groove 10 to push the rotating rod 6 to rotate synchronously. A cylinder 12 for pushing the rotating rod 6 downward to separate from the convex block 11 is provided on the top of the machine body 1. A first spring 13 in contact with the bottom of the rotating rod 6 is provided inside the rotating member 2; after using this device, when it is in normal use, the cylinder 12 does not push the rotating rod 6 downward. At this time, the convex block 11 is embedded in the groove 10 so that the rotating rod 6 is connected to the rotating member 2. Therefore, when the driving member 9 drives the rotating member 2 to rotate, the rotating rod 6 and the cleaning member 7 will be driven to rotate synchronously. On the contrary, when it needs to be cleaned after stirring, the cylinder 12 at the upper end of the rotating rod 6 is opened, so that the cylinder 12 pushes the rotating rod 6 downward and drives the cleaning member 7 and the blocking piece 8 to move downward. At the same time, the convex block 11 disengages from the groove 10 of the rotating rod 6. The external threads on the rotating rod 6 are in contact with the internal threads of the rotating member 2. At this time, the driving member 9 on the machine body 1 is further opened, and the driving member 9 controls the rotation of the rotating member 2. In this state, when the rotating member 2 rotates, the internal threads will be engaged with the external threads of the rotating rod 6, and the rotating rod 6 will be pushed downward by the threads. At the same time, one end of the cleaning member 7 that extends out is attached to the lower surface of the stirring member 3, and the other end is attached to the upper surface of the stirring member 3. At this time, after rotation, the stirring member 3 is embedded in the cleaning member 7, and the cleaning member 7 is driven by the stirring member 3 to move downward. When the cleaning member 7 moves, it will scrape off the material adhered to the surface of the stirring member 3 and continuously push it downward, thereby achieving the effect of cleaning the stirring member 3. And when the continuously downward moving cleaning member 7 is pushed to the bottom of the stirring member 3, the adhered material will be discharged downward. At the same time, the downward moving rotating rod 6 will compress the first spring 13. Secondly, the blocking piece 8 can block the material to prevent the cleaning member 7 from overflowing too much backward. Secondly, when the blocking piece 8 is vertically arranged to accumulate the material, it can also overflow to the side and directly fall to the bottom of the machine body 1. Through the above settings, the effect of automatically cleaning the stirring member 3 can be achieved, and it also avoids the adhesion of a large amount of material to the stirring member 3 after use, avoiding waste and also avoiding the reduction of the finished product rate in each processing.

[0034] One end of the elastic sheet 15 is provided with an arc-shaped rack 17. A first motor 18 is fixedly arranged inside the rotating member 2. A first gear 19 meshing with the rack 17 is clamped on the rotating shaft of the first motor 18. A first switch 20 for controlling the opening and closing of the first motor 18 is arranged on the rotating member 2 at the end of the sliding groove 4, and the first switch 20 abuts against the cleaning member 7 when it moves to the end of the sliding groove 4. A push plate 14 for pushing the adhered material on the cleaning member 7 is arranged at the bottom of the rotating member 2. The push plate 14 faces the cleaning member 7 after it rotates and moves downward. An elastic sheet 15 for pushing the push plate 14 to move is attached to the side of the rotating member 2. A first limiting member 16 for restricting the movement and straightening the elastic sheet 15 is arranged on the rotating member 2 at the position of the push plate 14. An oil film is coated on the surface of the cleaning member 7. The elastic sheet 15 cannot completely pass through the first limiting member 16. A second limiting member 21 for extruding the elastic sheet 15 to reset and fit on the rotating member 2 is arranged on the rotating member 2. Secondly, after the cleaning member 7 moves to the bottom of the stirring member 3, the stirring member 3 also moves to the end of the sliding groove 4 and opens the first switch 20, thereby controlling the opening of the first motor 18, so that the first motor 18 drives the first gear 19 to rotate and synchronously drives the rack 17 meshed with the first gear 19, so that the rack 17 rotates and is pushed to move by the meshed first gear 19, driving the connected elastic sheet 15, so that the elastic sheet 15 moves and moves outwards along the opening of the first limiting member 16. Under the limitation of the opening shape of the first limiting member 16, the elastic sheet 15 moves out horizontally, and pushes the push plate 14 to push the adhered material along the surfaces of the cleaning member 7 and the blocking piece 8 to fall outwards. Because the cleaning member 7, the blocking piece 8 and the push plate 14 are all coated with an oil film, the adhered material is easily dropped during the short-term pushing of the cleaning material. Compared with the stirring member 3, the contact time with the material is short and the oil film separation effect is good. Therefore, the adhered material is reduced and waste is avoided.

[0035] Conversely, after use, the switch for reversing the driving member 9 is turned on, so that the rotating member 2 and the stirring member 3 are reversed, and at the same time, the cleaning member 7 is pushed upwards to reset. At the same time, the switch for reversing the first motor 18 is also driven after moving upwards, so that the first gear 19 is reversed and drives the rack 17 to reset. Because of the reset, it moves along the first limiting member 16 again, and after passing through the second limiting member 21, the elastic sheet 15 is driven to reset, so that the elastic sheet 15 returns to an arc shape and fits on the rotating member 2 again, thereby ensuring that it will not affect stirring during rotation, or that materials will not pour in during stirring. At the same time, a moving sheet is arranged on the rotating member 2 on the sliding groove 4, and a spring is provided between the moving sheet and the rotating member 2. Thus, the moving sheet can be pushed upwards during movement, and can be pushed downwards by the spring to close the sliding groove 4 when the cleaning member 7 does not move, so as to reduce the entry of materials into the rotating member 2. However, no matter what stirring and cleaning objects are used, there will be material residues. After the above settings, the adhesion of materials on the surface of the stirring objects can be reduced.

[0036] The rotating member 2 is externally rotatably connected with a stirring rod 22, and the stirring rod 22 is located in the middle of the helix of the stirring member 3. The rotating member 2 is provided with a clamping groove 23 for accommodating the embedding of the stirring rod 22. The bottom of the clamping groove 23 is provided with a fixing block 24 for supporting and blocking the stirring rod 22 from moving downwards. A connecting rod 25 connected to the stirring rod 22 is slidably connected to the clamping groove 23. One end of the connecting rod 25 away from the clamping groove 23 is provided with a sleeve 26. The sleeve 26 is sleeved on the stirring rod 22, and the sleeve 26 is rotatably connected to the connecting rod 25. In the normal state of use, the stirring rod 22 is located in the middle of the two spiral parts of the stirring member 3, ensuring that the rotation of the rotating member 2 drives the stirring rod 22 to rotate synchronously, so that the stirring rod 22 pushes the materials away from the stirring member 3, making the materials flow better and mix with the materials at the stirring member 3, increasing the degree of material mixing and improving the mixing speed. At the same time, after the materials are discharged, the stirring rod 22 located between the two spiral parts of the stirring member 3 will not restrict or block the downward movement of the cleaning member 7. At the same time, the clamping groove 23 does not completely penetrate (pierce) the rotating member 2, but the intersection of the stirring member 3 and the clamping groove 23 is in a disconnected state, ensuring that the stirring rod 22 will not be blocked by the stirring member 3 when it is retracted. Secondly, the moving piece for closing the chute 4 at the clamping groove 23 and the moving piece on the side of the clamping groove 23 are disconnected and move independently, so as to prevent the stirring rod 22 and the sleeve 26 from being blocked and restricted by the moving piece when moving and embedding into the clamping groove 23.

[0037] A rolling member 27 is provided at one end of the connecting rod 25 located in the card slot 23. A connecting rope 28 is provided on the rolling member 27. The other end of the connecting rope 28 extends to the upper end of the rotating rod 6 for connection. A guiding groove 29 for accommodating the sliding of the rolling member 27 and guiding the movement of the rolling member 27 is provided inside the card slot 23. A roller 34 for accommodating the movement of the connecting rope 28 is provided between the winding roller 33 and the rotating rod 6. The connecting rope 28 between the winding roller 33 and the rotating rod 6 is a buffer section, and the buffer section is in a relaxed state. The length of the buffer section is set according to the distance that the cleaning member 7 moves to the lower end of the stirring rod 22. Under normal conditions, the stirring rod 22 is horizontally arranged and cooperates with the stirring member 3 to stir the material. When the cleaning member 7 moves downward, it will pull the connecting rope 28 downward, and slowly straighten the originally loose buffer section. After the buffer section is straightened, due to the continuous downward movement of the rotating rod 6, it will continue to drive the connecting rope 28 downward. At this time, the connecting rope 28 will pull the winding roller 33 to rotate, and the connecting rope 28 at the end connected to the rotating rod 6 of the winding roller 33 extends outward, while the other end of the winding roller 33 continues to wind the connecting rope 28 and pulls the rolling member 27 upward. Thus, the rolling member 27 drives the connecting rod 25 to move upward together, and when the connecting rod 25 moves upward, it will pull the kit 5 upward synchronously. The kit 5 is sleeved outside the stirring rod 22, but the stirring rod 22 cannot move upward and can only rotate upward. Thus, when the kit 5 moves upward, it will push the stirring rod 22 to rotate, and the connecting rod 25 also rotates along the kit 5. And as the kit 5 continuously moves, it will also move along the stirring rod 22 to scrape off the material adhered to the surface of the stirring rod 22. Secondly, when the rotating rod 6 moves downward and straightens the buffer section of the connecting rope 28, the positions of the rotating rod 6 and the cleaning member 7 are already lower than the stirring rod 22. Thus, it is ensured that when the rotating rod 6 continues to move downward to drive the stirring rod 22 through the connecting rope 28, the rotating rod 6 will not contact or block the stirring rod 22. Secondly, the connecting rope 28 is disconnected at the sliding groove 4, and the upper and lower parts of the connecting rope 28 at the disconnection point are adsorbed to each other by a strong magnet 37. A support piece 38 for supporting the strong magnet 37 is provided at the lower end of the guiding groove 29 where the sliding groove 4 is located. By the support of the support piece 38, it is ensured that the connecting rope 28 will not fall. Thus, when the cleaning member 7 moves to the connecting rope 28, due to the thrust, the upper and lower strong magnets 37 are separated, and under the support of the support piece 38, the connecting rope 28 will not fall. Thus, after the cleaning member 7 passes through, the two ends of the connecting rope 28 at the strong magnet 37 are re-adsorbed, and the adsorption force of the strong magnet 37 can support the force for pulling the stirring rod 22. Thus, it is ensured that the pulling will not be disconnected. Secondly, after the cleaning member 7 is reset and moves upward and is about to reach the stirring rod 22, the stirring rod 22 will reset due to the second spring 36, the first spring 35, and its own weight, ensuring that when the cleaning member 7 moves to the sliding groove 4 where the connecting rope 28 is located again, it can still be separated by the strong magnet 37, avoiding the situation of blocking the movement of the connecting rope 28. At the same time, the support piece 38 is located on the side of the guiding groove 29 and will not hinder the movement of the rolling member 27.

[0038] The rolling member 27 is clamped with a second gear 30 in the middle. A second rack 31 that abuts against the second gear 30 is provided at the upper end of the guide groove 29. A winding roller 33 for accommodating the winding of the connecting rope 28 is provided on the rotating member 2, and the winding roller 33 is rotatably connected to the rotating member 2. Both ends of the connecting rope 28 extend from the front and rear ends of the winding roller 33 and are respectively connected to the rolling member 27 and the rotating rod 6. Finally, after the connecting rope 28 is continuously pulled upward, when the rolling member 27 moves upward along the guide groove 29, it will drive the second gear 30 to move upward synchronously. When the second gear 30 abuts against the bottom teeth of the second rack 31 and continues to move upward, the second gear 30 will engage with the second rack 31. Driven by the engagement with the second rack 31, the second gear 30 will rotate, and drive the rolling member 27 and the connecting rod 25 to rotate synchronously and push the other end of the connecting rod 25 to rotate with the kit 5, and pull the kit 5 and the stirring rod 22 to be inserted into the card slot 23. The connecting rod 25 is inserted into the guide groove 29. After the above settings, it can be ensured that the stirring rod 22 is cleaned simultaneously when the stirring member 3 is cleaned. Therefore, there is no need for manual cleaning, and relatively large pieces of adhered materials can be removed, falling downward into the bottom of the equipment and discharged, reducing material waste while increasing the discharge rate, and saving time and improving efficiency without manual labor. A first spring 35 for pushing the winding roller 33 to reset is provided inside the winding roller 33. A second spring 36 is provided between the stirring rod 22 and the rotating member 2. The elastic forces of the first spring 35 and the second spring 36 are greater than the force of the stirring rod 22 colliding and stirring with the material, and the elastic forces of the first spring 35 and the second spring 36 are less than the force of the rotating rod 6 moving downward. On the contrary, by turning on the switch that controls the reverse rotation of the rotating member 2 of the machine body 1, the rotating member 2 rotates in reverse. At this time, it will drive the rotating rod 6 to move upward, and at the same time drive the cleaning member 7 to move upward to cancel the compression of the first spring 13 and cancel the pulling of the connecting rope 28. And the elastic force of the first spring 35 inside the winding roller 33 will drive the winding roller 33 to rotate in reverse and rewind the connecting rope 28 at the rotating rod 6. Correspondingly, the second spring 36 in the stirring rod 22 will push the stirring rod 22 to rotate downward, and drive the kit 5 to move downward. And the kit 5 is restricted by the connecting rod 25 and then moves downward along the stirring rod 22, and pulls the connecting rod 25, the rolling member 27 and the second gear 30 downward. Thus, the reset of the stirring rod 22 ensures the next use. At the same time, the stirring rod 22 is pushed against the fixed block 24 by the second spring 36 to support and reset the stirring rod 22. The elastic force of the second spring 36 is greater than the material resistance to ensure that the stirring rod 22 does not shake during stirring. At the same time, the cleaning member 7 resets to the upper end of the stirring member 3. After moving to the starting position of the sliding groove 4, at this time, the first spring 13 will push the rotating rod 6 upward, thereby driving the cleaning member 7 to move upward and reset. This ensures that cleaning can continue after subsequent processing.

[0039] First, the materials to be processed and mixed are introduced into the machine body 1 from the uppermost inlet of the machine body 1. The control program of the machine body 1 is set in advance by the PLC to control the driving part 9, and the stirring part 3 is driven to rotate, continuously stirring and mixing the materials. The stirring part 3 and the stirring rod 22 switch the forward and reverse rotation according to the stirring degree and time. At the same time, when the materials in the machine body 1 need to be heated, the switch of the heating wire inside the machine body 1 can be turned on to heat the materials so that they can be stirred better. After repeated mixing to the required degree, the bottom of the machine body 1 is opened to discharge the materials, and the mixing is completed;

[0040] Secondly, after stirring, the switch of the outer cylinder 12 of the machine body 1 is turned on. At the same time, the cylinder 12 moves downward and drives the rotating rod 6 to move downward, so that the convex block 11 is separated from the groove 10. Thus, the bottom of the external thread of the rotating rod 6 abuts and is embedded with the upper end of the internal thread of the rotating part 2. The downward movement of the rotating rod 6 drives the cleaning part 7 to fit with the stirring part 3. In this way, the middle gap between the upper end of the stirring part 3 and the cleaning part 7 is opposite. Then, the driving part 9 is turned on to rotate forward again, so as to drive the stirring part 3 to be embedded into the gap of the cleaning part 7. At the same time, after the rotating rod 6 is driven by the rotating part 2 to move downward, when the stirring part 3 continues to rotate, it will continue to move along the gap of the cleaning part 7 and drive the cleaning part 7 to move downward;

[0041] Finally, after rotating to the bottom, the switch 20 is turned on, so that the gear 19 drives the rack 17 to move, and the rack 17 drives the elastic sheet 15 to drive the push plate 14 to move, scraping the residual materials along the surface of the cleaning part 7. At this time, the switch for separately controlling the reverse rotation of the driving part 9 outside the machine body 1 is turned on, so that the cleaning part 7 is reset and the reverse rotation switch of the motor 18 is driven, so that the elastic sheet 15 is reset.
