Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cashmere blending, in particular to a mixing device and production process for brewing protein fiber and cashmere fiber. BACKGROUND

[0002] Brewing protein fiber is a protein polymer fiber produced by microbial fermentation, and its production process is similar to brewing beer. Plant-synthesized sugar such as sugarcane and corn is used as raw material to produce protein polymer through microbial fermentation. Brewing protein fiber has the characteristics of high strength, softness, and air permeability. The fiber diameter can be freely controlled, thereby producing a unique texture that is very delicate and soft. Since the fiber strength and elongation of brewing protein fiber change greatly after absorbing moisture, only cashmere oil and water additives are added to the cashmere fiber during combing, and no additives are directly added to the brewing protein fiber. The cashmere fiber raw material is opened twice during combing, and cashmere oil additives are added. Then, the warehouse is soaked for more than 24 hours to ensure that the oil and water are fully absorbed. The brewing protein fiber is opened separately before mixing to make the brewing protein fiber fluffy. Finally, the cashmere fiber and the brewing protein fiber are mixed evenly.

[0003] During actual mixing, the surface of the brewing protein fiber is relatively smooth and has a longitudinally grooved structure designed by humans, and the frictional resistance is small, making it easier to be carried by airflow or pulled by mechanical parts, and moving faster in the combing equipment. The surface of the cashmere fiber is covered with scales, and the crimping degree is high, and the frictional resistance between fibers is large, which is easy to wind into a bundle. Friction of cashmere fiber also easily generates static electricity, which causes it to be adsorbed on the inner wall of the equipment. Therefore, the movement speed of cashmere fiber is significantly slower than that of brewing protein fiber. The speed difference causes the two fibers to be easily separated by airflow in the combing machine, with brewing protein fiber gathering at the front end of the feeding curtain, and cashmere fiber remaining in the rear section of the feeding curtain. The brewing protein fiber may account for a high proportion in the fed fiber, leading to uneven mixing, and the subsequent spinning may easily cause "stripes" or "cloud spots". Therefore, we propose a mixing device and production process for brewing protein fiber and cashmere fiber. SUMMARY

DETAILED DESCRIPTION

[0018] Clearly, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts are within the scope of the present application.

[0019] Please refer to Figures 1-11 The present application provides a technical scheme: a mixed device for brewing protein fiber and cashmere fiber, comprising a feeding bin 1, a feeding hopper 2 fixedly installed on the upper end of the feeding bin 1, an opening device 3 and a fan 5 (the opening device 3 and the fan 5 are existing known structures, so the present application will not be described in more detail), a feeding curtain 6 for conveying fiber raw materials is arranged in the feeding bin 1, a pressing roller 7 is rotatably installed at the outlet of the feeding bin 1, the feeding curtain 6 and the pressing roller 7 are driven to move by the opening device 3, a pushing plate 18 for pushing the fiber at the rear end to the front end is arranged in the feeding bin 1, a bidirectional telescopic rod 17 is fixedly installed on the pushing plate 18, two first air cylinders 15 are fixedly installed in the feeding bin 1, a sliding frame 16 for limiting the bidirectional telescopic rod 17 is fixedly installed at the output end of each first air cylinder 15, the two ends of the bidirectional telescopic rod 17 are respectively vertically slidably installed in the corresponding sliding frame 16, a limiting shaft 19 is fixedly installed at the two ends of the bidirectional telescopic rod 17, a guide frame 20 for limiting the limiting shaft 19 is fixedly installed on the inner wall of the feeding bin 1 on both sides, the guide frame 20 is arranged in a right triangle, two material blocking strips 21 for blocking the fiber are fixedly installed in each guide frame 20, each material blocking strip 21 is made of elastic material and can deform correspondingly with the movement of the bidirectional telescopic rod 17, an inclined slot 22, a horizontal slot 23 and a vertical slot 24 matched with the limiting shaft 19 are arranged in each guide frame 20, and the three slot bodies are arranged in a head-to-tail communication mode, a limiting block 25 for limiting the limiting shaft 19 is arranged at the end of each inclined slot 22, a material guide plate 47 for guiding the fiber is fixedly installed in the feeding bin 1, a first magnetic block 28 and a second magnetic block 29 are fixedly installed on each limiting shaft 19, a first magnetic strip 26 magnetically attracted to the first magnetic block 28 is fixedly installed on the inner wall of each inclined slot 22, a second magnetic strip 27 magnetically attracted to the second magnetic block 29 is fixedly installed on the inner wall of each horizontal slot 23 and vertical slot 24, the first magnetic block 28 and the second magnetic strip 27 are magnetically repelled, the second magnetic block 29 and the first magnetic strip 26 are magnetically repelled, in the initial state, as shown in the attached Figure 3As shown, the first cylinder 15 is in the extended state, the pushing plate 18 is located at the rear end of the wool feeding bin 1, the limiting shaft 19 is located at the first end of the inclined groove 22, the two-way telescopic rod 17 is located at the bottom end of the sliding frame 16, and the second magnetic strip 27 on the inner wall of the vertical groove 24 attracts the second magnetic block 29, so that the pushing plate 18 is in a vertical state and does not affect the fibers falling onto the wool curtain 6. When the fibers enter from the feeding hopper 2, the first cylinder 15 will perform reciprocating extension and retraction movement. When the first cylinder 15 retracts, it will drive the sliding frame 16 to move synchronously. At the same time, as shown in the attached Figure 4 As shown, the limiting shaft 19 will move upward along the inclined groove 22, and the two-way telescopic rod 17 will slide upward in the sliding frame 16. The magnetic attraction between the first magnetic strip 26 and the first magnetic block 28 causes the limiting shaft 19 to drive the two-way telescopic rod 17 and the pushing plate 18 to rotate by a certain amplitude, so that the pushing plate 18 is in an inclined state. Then, as the pushing plate 18 moves, the fibers at the rear section of the wool feeding bin 1 will be moved upward by the pushing plate 18, and the fibers at the middle section of the wool feeding bin 1 will not be affected. The lower end of the pushing plate 18 is arc-shaped, which can prevent the fibers from falling during movement. When the limiting shaft 19 moves to the end of the inclined groove 22, it will slide along the inclined surface of the limiting block 25 and make both ends of the two-way telescopic rod 17 contract inward. When the first cylinder 15 is fully retracted, the limiting shaft 19 will pass through the inclined surface of the limiting block 25 and be stretched back by the elastic force of the two-way telescopic rod 17. At the same time, the limiting shaft 19 will enter the horizontal groove 23, and the second magnetic block 29 will be attracted by the magnetic attraction of the second magnetic strip 27 on the inner wall of the horizontal groove 23, driving the limiting shaft 19 and the pushing plate 18 to rotate again, as shown in the attached Figure 7 As shown, the pushing plate 18 will rotate to a horizontal state, and the raw fibers at the rear section of the pushing plate 18 will be thrown to the front end of the wool feeding bin 1, making the raw materials more evenly mixed. Then the first cylinder 15 will be extended again, as shown in the attached Figure 5 As shown, the pushing plate 18 will be limited by the straight surface of the limiting block 25 and slide along the horizontal groove 23, keeping a horizontal state and moving to the rear section of the wool feeding bin 1, reducing the impact on the fibers. When the first cylinder 15 is fully extended, the limiting shaft 19 will move to the position where the vertical groove 24 and the horizontal groove 23 are connected. The gravity of the pushing plate 18 will drive the limiting shaft 19 to move downward in the vertical groove 24, and the two-way telescopic rod 17 will move downward in the sliding frame 16. Through the attraction of the second magnetic block 29 by the second magnetic strip 27 on the inner wall of the vertical groove 24, the limiting shaft 19 will drive the pushing plate 18 to flip to the initial vertical state and move to the initial position at the first end of the inclined groove 22. Then the first cylinder 15 will retract again, so that the wool fibers remaining in the rear section of the wool feeding bin 1 are continuously pushed to the front end of the wool feeding bin 1 and mixed with the brewing protein fibers, improving the uniformity of the mixture of the two fiber raw materials.

[0020] The first stirring shaft 13 and the second stirring shaft 14 for stirring fibers are rotatably installed at the front end of the feeding bin 1, the rotating directions of the first stirring shaft 13 and the second stirring shaft 14 are the same as the moving direction of the feeding curtain 6, the stirring shaft parts of the first stirring shaft 13 and the second stirring shaft 14 are cross arranged, the first transmission wheel 10 and the second transmission wheel 11 are respectively fixedly installed at the end of the first stirring shaft 13 and the end of the second stirring shaft 14, the motor 8 is fixedly installed on the outer wall of the feeding bin 1, the belt pulley 9 is fixedly installed at the output end of the motor 8, the belt 12 is transmissionally installed between the belt pulley 9, the first transmission wheel 10 and the second transmission wheel 11, the baffle 48 for isolating fibers is fixedly installed in the feeding bin 1, the scraping plate 30 for controlling the feeding amount is slidingly installed at the lower end of the baffle 48, the first springs 32 are fixedly connected between the scraping plate 30 and the baffle 48, the wedge block 33 is fixedly installed at one end of the scraping plate 30, the limiting strips 34 matched with the wedge block 33 are fixedly installed at the end of the second stirring shaft 14, the limiting strips 34 correspond to the stirring shaft parts on the second stirring shaft 14, the angle nails 31 for grabbing fibers are fixedly installed on the feeding curtain 6, the angle nails 31 are also fixedly installed at the lower end of the scraping plate 30, the angle nails 31 on the feeding curtain 6 are all inclined to the moving direction of the feeding curtain 6, the angle nails 31 at the lower end of the scraping plate 30 are inclined in the opposite direction to the angle nails 31 on the feeding curtain 6, after the fibers enter the feeding bin 1, the motor 8 will also be started, and drives the first stirring shaft 13 and the second stirring shaft 14 to rotate through the transmission of the belt 12, and since the rotating directions of the first stirring shaft 13 and the second stirring shaft 14 are the same as the moving direction of the feeding curtain 6, the fibers conveyed on the feeding curtain 6 and the fibers at the front end of the feeding bin 1 will be first rolled up by the first stirring shaft 13, the fibers at the rear section of the feeding bin 1 pushed by the pushing plate 18 will be thrown onto the guide plate 47, and then fall onto the first stirring shaft 13 along the inclined surface of the guide plate 47, and mix with the fibers at the front end of the feeding bin 1 on the first stirring shaft 13, and then the mixed fibers will be picked up again by the second stirring shaft 14 for mixing, and finally fall onto the feeding curtain 6 at the front end of the second stirring shaft 14, which can effectively mix the fibers at the rear section and the front end of the feeding bin 1 uniformly, and can throw the uniformly mixed fibers onto the feeding curtain 6, the fibers on the feeding curtain 6 can all be twice mixed by the first stirring shaft 13 and the second stirring shaft 14, which improves the mixing efficiency, meanwhile, the limiting strips 34 at the end of the second stirring shaft 14 are synchronously rotated by the second stirring shaft 14, when the end of the limiting strip 34 contacts the inclined surface of the wedge block 33, the limiting strip 34 will drive the wedge block 33 to synchronously slide, so that the scraping plate 30 moves away from the second stirring shaft 14, and the first springs 32 are compressed, since the limiting strips 34 correspond to the stirring shaft parts on the second stirring shaft 14, when the limiting strips 34 contact the wedge block 33, the stirring rod parts of the second stirring shaft 14 will drive the fiber raw materials after stirring to move above the feeding curtain 6, and then the fibers will fall onto the feeding curtain 6, when the limiting strips 34 pass the wedge block 33, the scraping plate 30 will be reset by the pushing of the first springs 32,The scraper 30 pushes excess fibers from the feeding curtain 6 back below the second stirring shaft 14. The airflow generated by the scraper 30's repositioning slows the flow rate of the brewing protein fibers. After entering the lower end of the second stirring shaft 14, the excess fibers are driven upwards by its stirring rods, and then stirred again by the stirring rods of the first stirring shaft 13. As the first stirring shaft 13 rotates, it undergoes another stirring and conveying cycle. As the limiting strip 34 continuously contacts the inclined surface of the wedge block 33, the wedge block 33 drives the scraper 30 to slide back and forth, continuously scraping away excess fibers from the feeding curtain 6. The feeding curtain 6, through its upper corner nails 31, grips the fibers, ensuring a constant amount of fibers are conveyed into the opening device 3.

[0021] A second cylinder 35 is fixedly installed at the upper end of the detection chamber 4. A collection frame 36 for collecting fibers is fixedly installed at the output end of the second cylinder 35. A pressure sensing plate 37 for detecting the weight of the collection frame 36 is fixedly installed at the connection between the second cylinder 35 and the collection frame 36. Several ventilation slots 38 are provided on the collection frame 36. A base plate 39 is rotatably installed at the bottom of the collection frame 36. A baffle plate 41 for preventing fiber leakage from the collection frame 36 is fixedly installed on the detection chamber 4. A discharge plate 42 for pushing out the fibers is slidably installed on the collection frame 36. Several second springs 49 are fixedly connected between the discharge plate 42 and the inner wall of the top of the detection chamber 4. Several elastic strips 43 are fixedly installed on the material frame 36. Several slots 44 for limiting the elastic strips 43 are provided on the unloading plate 42. Each slot 44 corresponds to one elastic strip 43. Torsion springs 40 are fixedly connected to the material frame 36 at both ends of the bottom plate 39. Several magnetic plates 46 are fixedly installed on the bottom plate 39. Several magnetic rods 45 that cooperate with the magnetic plates 46 are fixedly installed on the unloading plate 42. Each magnetic rod 45 corresponds to one magnetic plate 46. After being opened by the opening device 3, the fibers will be attracted into the detection chamber 4 by the wind force of the fan 5. The second cylinder 35 will start at regular intervals, pushing the material frame 36 into the detection chamber 4. Figure 9As shown, in the initial state, the second cylinder 35 is in the retracted state, the collection frame 36 does not enter the detection chamber 4, and does not affect the passage of fibers. At the same time, the ejector plate 42 is located at the lower end of the collection frame 36. Through the repulsion between the magnetic rod 45 and the upper magnetic pole of the magnetic plate 46, the bottom plate 39 overcomes the elastic force of the torsion spring 40 and rotates 180 degrees, so that the lower magnetic pole of the magnetic plate 46 attracts the magnetic rod 45. After the bottom plate 39 is flipped, it does not affect the passage of fibers, and the ejector plate 42 can seal the bottom of the collection frame 36 to prevent fibers from entering. When the second cylinder 35 is started and extended, the magnetic plate 46 on the bottom plate 39 is no longer affected by the magnetism of the magnetic rod 45, and the elastic force of the torsion spring 40 will pull the bottom plate 39 to flip 180 degrees. The bottom plate 39 seals the bottom of the collection frame 36. After the second cylinder 35 extends completely, the collection frame 36 will be fully inserted into the detection chamber 4. The elastic strip 43 will deform and enter the corresponding slot 44. The blower 5 will draw the air and fibers from the opening device 3 into the detection chamber 4. The airflow passes through the ventilation groove 38, and all the fibers enter the collection frame 36. By adjusting the amount of fibers on the feeding curtain 6 through the scraper 30, the weight of fibers output by the opening device 3 should be kept within a reasonable range for a certain period of time. After the second cylinder 35 extends for a period of time, a certain amount of fibers will be stored in the collection frame 36. Then the second cylinder 35 will retract, driving the bottom plate 39 to rise. The baffle plate 41 prevents the fibers in the collection frame 36 from escaping. The elastic strip 43 is limited by the slot 44, causing the collection frame 36 to move upwards along with the ejector plate 42. After the second cylinder 35 retracts, the collection frame 36 returns to its initial state, and the fibers inside are no longer affected by airflow. All the fibers inside the collection frame 36 fall onto the bottom plate 39. At this time, the pressure sensing plate 37 detects the weight of the collection frame 36 and its internal fibers. If the weight is within a reasonable range, it indicates that the two raw materials are mixed evenly and no longer separate due to speed differences caused by different friction coefficients. If the weight is too heavy, it indicates uneven mixing, because the density of brewing protein fibers... The material is relatively large, so the content of brewing protein fiber in the collection frame 36 is relatively large. If the weight is too light, it means that the raw material supply is insufficient and the raw material fiber conveyed by the feeding curtain 6 is too little. When the ejector plate 42 moves upward, the second spring 49 is continuously compressed. After the second cylinder 35 retracts, the elastic force of the second spring 49 will be greater than the pushing force required for the elastic strip 43 to deform. The ejector plate 42 will be pushed downward by the elastic force of the second spring 49 to reset, and push the fiber in the collection frame 36 downward. When the ejector plate 42 is about to reset, the magnetic repulsion force generated by the magnetic rod 45 and the upper end of the magnetic plate 46 will push the bottom plate 39 to rotate 180 degrees. The fiber can be pushed back into the detection chamber 4, and the ejector plate 42 can also reset.

[0022] Specifically, fibers are fed into the feeding bin 1 from the feed hopper 2 via airflow. Simultaneously, the first cylinder 15 reciprocates. When the first cylinder 15 retracts, it drives the sliding frame 16 to move synchronously. The limiting shaft 19 drives the pusher plate 18 to rotate to a certain extent, causing the pusher plate 18 to be in an inclined state. Then, it moves obliquely upwards along the inclined groove 22. The fibers in the rear section of the feeding bin 1 are driven obliquely upwards by the pusher plate 18. When the limiting shaft 19 reaches the end of the inclined groove 22, it slides along the inclined surface of the limiting block 25, causing both ends of the bidirectional telescopic rod 17 to retract inwards. When the first cylinder 15 has finished retracting, the limiting shaft 19 passes the inclined surface of the limiting block 25 and is extended and reset by the elastic force of the bidirectional telescopic rod 17. At the same time, the limiting shaft 19 enters the water... Inside the horizontal groove 23, the limiting shaft 19 drives the pusher plate 18 to rotate to a horizontal state. The raw material fibers on the rear section of the pusher plate 18 will be thrown down to the front end of the feeding bin 1. Then, the first cylinder 15 will extend again, and the pusher plate 18 will be limited by the straight surface of the limiting block 25, sliding along the horizontal groove 23 and moving towards the rear section of the feeding bin 1 while maintaining a horizontal state. When the first cylinder 15 has finished extending, the limiting shaft 19 will move to the point where the horizontal groove 23 connects with the vertical groove 24. The pusher plate 18 will move downward under gravity and flip back to its initial vertical state. Then, the first cylinder 15 will retract again, so that the wool fibers retained in the rear section of the feeding bin 1 will be continuously pushed to the front end of the feeding bin 1 to mix with the brewing protein fibers. At the same time, the motor 8 will also start and drive the first stirring shaft 13 and the second stirring shaft. As the second stirring shaft 14 rotates, the fibers conveyed on the feeding curtain 6 and the fibers at the front end of the feeding bin 1 are first rolled upwards by the first stirring shaft 13. The fibers at the rear end of the feeding bin 1, pushed by the pusher plate 18, are thrown onto the guide plate 47 and fall along the inclined surface of the guide plate 47 onto the first stirring shaft 13, where they mix with the fibers at the front end of the feeding bin 1 on the first stirring shaft 13. The mixed fibers are then picked up and mixed again by the second stirring shaft 14, and finally fall onto the feeding curtain 6 at the front end of the second stirring shaft 14. At the same time, the second stirring shaft 14 drives its end limiting strip 34 to rotate synchronously. When the end of the limiting strip 34 contacts the inclined surface of the wedge block 33, it pushes the wedge block 33 to move the scraper plate 30 away from the second stirring shaft 14. Then, the fibers on the second stirring shaft 14 fall onto the feeding curtain 6. When the limiting strip 34 passes the wedge block 33, the scraper plate 30 will be pushed back to its original position by the first spring 32. The scraper plate 30 pushes the excess fibers on the feeding curtain 6 back to below the second stirring shaft 14. The airflow generated by the scraper plate 30's reset can slow down the flow speed of the brewing protein fibers. After the excess fibers enter the lower end of the second stirring shaft 14, they will be driven upward by its stirring rods, and then stirred again by the stirring rods of the first stirring shaft 13. With the rotation of the first stirring shaft 13, the fibers will be stirred and conveyed again. As the limiting strip 34 continuously contacts the inclined surface of the wedge block 33, the wedge block 33 will drive the scraper plate 30 to slide back and forth, continuously scraping off the excess fibers on the feeding curtain 6, and always maintaining a certain amount of fibers being conveyed into the opening device 3.After being opened by the opening device 3, the fibers are drawn into the testing chamber 4 by the airflow from the blower 5. The second cylinder 35 is activated periodically, pushing the collection frame 36 into the testing chamber 4. The magnetic plate 46 on the bottom plate 39 is no longer affected by the magnetism of the magnetic rod 45. The spring force of the torsion spring 40 pulls the bottom plate 39 to rotate 180 degrees, sealing the bottom of the collection frame 36. After the second cylinder 35 extends completely, the collection frame 36 is fully inside the testing chamber 4. The blower 5 draws air and fibers from the opening device 3 into the testing chamber 4. The airflow passes through the ventilation groove 38, and all the fibers enter the collection frame 36. After the second cylinder 35 extends for a period of time, it retracts, and the collection frame 36 moves upward along with the unloading plate 42. After the second cylinder 35 retracts completely... Afterwards, the collection frame 36 will return to its initial state. The pressure sensing plate 37 will detect the weight of the collection frame 36 and its internal fibers. If the weight is within a reasonable range, it indicates that the two raw materials are mixed evenly and no longer separate due to the speed difference caused by the different friction coefficients. If the weight is too heavy, it indicates that the mixing is uneven and the content of brewing protein fiber in the collection frame 36 is too high. If the weight is too light, it indicates that the raw material supply is insufficient and the raw material fiber conveyed by the feeding curtain 6 is too little. After the second cylinder 35 retracts, the ejector plate 42 will be pushed downward by the elastic force of the second spring 49 to reset, pushing the fibers in the collection frame 36 downward. The magnetic repulsion force generated by the magnetic rod 45 and the upper end of the magnetic plate 46 will push the bottom plate 39 to rotate 180 degrees, allowing the fibers to be pushed back into the detection chamber 4.

[0023] A production process for a brewing apparatus for blending protein fibers and cashmere fibers specifically includes the following steps: S1. First, loosen the cashmere fiber raw material twice and add loosening oil. After the raw material has been sealed for at least one hour, loosen it once with a loosening machine. Then pack it and seal it in a warehouse for more than 24 hours to ensure that the oil and water are fully absorbed. S2. The brewing protein fiber is individually opened to make its fiber state fluffy; S3. The two fibers are laid in cross layers and then horizontally and vertically. The two raw materials are fed into the wool mixing equipment by airflow and mixed evenly. S4. Fibers enter the feeding bin 1 from the feed hopper 2. The first cylinder 15 reciprocates. When the first cylinder 15 retracts, the limiting shaft 19 drives the pusher plate 18 to rotate to a certain extent, causing the pusher plate 18 to be in an inclined state. Then, it moves obliquely upward along the inclined groove 22. The fibers in the rear section of the feeding bin 1 will be driven obliquely upward by the pusher plate 18. When the first cylinder 15 has finished retracting, the limiting shaft 19 will enter the horizontal groove 23. The limiting shaft 19 drives the pusher plate 18 to rotate to a horizontal state, and the raw material fibers in the rear section of the pusher plate 18... The fibers will be thrown down to the front end of the feeding bin 1, and then the first cylinder 15 will extend again. The pusher plate 18 will remain horizontal and slide along the horizontal groove 23. When the first cylinder 15 has fully extended, the gravity of the pusher plate 18 will drive the limiting shaft 19 to move downward in the vertical groove 24 and flip back to the initial vertical state. At the same time, the motor 8 will drive the first stirring shaft 13 and the second stirring shaft 14 to rotate. The fibers conveyed on the feeding curtain 6 and the fibers at the front end of the feeding bin 1 will first be rolled up by the first stirring shaft 13, and the fibers pushed by the pusher plate 18 will move along the guide... The material plate 47 falls onto the first stirring shaft 13 at an incline, where it mixes with the fibers at the front end of the feeding bin 1 on the first stirring shaft 13. The mixed fibers are then picked up and mixed again by the second stirring shaft 14, and finally fall onto the feeding curtain 6 at the front end of the second stirring shaft 14. At the same time, the second stirring shaft 14 drives its end limiting strip 34 to rotate synchronously. After the end of the limiting strip 34 contacts the incline of the wedge block 33, it pushes the wedge block 33 to move the scraper 30 away from the second stirring shaft 14. After the limiting strip 34 passes the wedge block 33, the scraper 30 will be pushed by the first spring 32. The scraper 30 resets and pushes the excess fibers on the feeding curtain 6 back to below the second stirring shaft 14. The airflow generated by the reset of the scraper 30 can slow down the flow speed of the brewing protein fibers. After the excess fibers enter the lower end of the second stirring shaft 14, they will be driven upward by its stirring rods and then stirred again by the stirring rods of the first stirring shaft 13. As the first stirring shaft 13 rotates, it will be stirred and conveyed again. The scraper 30 continuously scrapes off the excess fibers on the feeding curtain 6, and always maintains a certain amount of fibers being conveyed into the opening device 3. S5. After being opened by the opening device 3, the fibers will be drawn into the testing chamber 4 by the airflow from the blower 5. The second cylinder 35 will start at regular intervals, pushing the collection frame 36 into the testing chamber 4. The spring force of the torsion spring 40 pulls the bottom plate 39 to rotate 180 degrees, sealing the bottom of the collection frame 36. After the second cylinder 35 has extended completely, the collection frame 36 will be fully inside the testing chamber 4. The blower 5 will draw the air and fibers from the opening device 3 into the testing chamber 4. The airflow passes through the ventilation groove 38, and all the fibers enter the collection frame 36. The second cylinder 35... 5. After extending for a period of time, it retracts. The material collection frame 36 moves upward together with the material ejection plate 42. After the second cylinder 35 retracts, the material collection frame 36 returns to its initial state. The pressure sensing plate 37 will detect the weight of the material collection frame 36 and the fibers inside it. At the same time, the material ejection plate 42 will be pushed downward by the elastic force of the second spring 49 to reset and push the fibers in the material collection frame 36 downward. The magnetic repulsion force generated by the magnetic rod 45 and the upper end of the magnetic plate 46 will push the bottom plate 39 to rotate 180 degrees, and the fibers can be pushed back into the detection chamber 4. S6. The two raw material fibers are repeatedly mixed through the wool mixing equipment. After the mixture is evenly mixed, the moisture regain of the raw material after wool mixing is detected and controlled.

A production process for a brewing apparatus for mixing protein fibers and cashmere fibers, characterized in that: The production process using the brewing protein fiber and cashmere fiber mixing apparatus as described in claim 9 specifically includes the following steps: S1. First, loosen the cashmere fiber raw material twice and add loosening oil. After the raw material has been sealed for at least one hour, loosen it once with a loosening machine. Then pack it and seal it in a warehouse for more than 24 hours to ensure that the oil and water are fully absorbed. S2. The brewing protein fiber is individually opened to make its fiber state fluffy; S3. The two fibers are laid in cross layers and then horizontally and vertically. The two raw materials are fed into the wool mixing equipment by airflow and mixed evenly. S4. Fibers enter the feeding bin (1) from the feed hopper (2). The first cylinder (15) reciprocates. When the first cylinder (15) retracts, the limiting shaft (19) drives the pusher plate (18) to rotate to a certain extent, so that the pusher plate (18) is in an inclined state. Then, it moves obliquely upward along the inclined groove (22). The fibers in the rear section of the feeding bin (1) will be driven obliquely upward by the pusher plate (18). When the first cylinder (15) finishes retracting, the limiting shaft (19) will enter the horizontal groove (23). The limiting shaft (19) drives the pusher plate (18) to rotate to a horizontal state. The raw materials in the rear section of the pusher plate (18) will be moved obliquely upward. The fibers will be thrown down to the front end of the feeding bin (1), and then the first cylinder (15) will extend again. The pusher plate (18) will slide along the horizontal groove (23) while maintaining a horizontal state. When the first cylinder (15) has finished extending, the gravity of the pusher plate (18) will drive the limiting shaft (19) to move downward in the vertical groove (24) and flip back to the initial vertical state. At the same time, the motor (8) will drive the first stirring shaft (13) and the second stirring shaft (14) to rotate. The fibers conveyed on the feeding curtain (6) and the fibers at the front end of the feeding bin (1) will first be rolled up by the first stirring shaft (13), and the fibers pushed by the pusher plate (18) will be rolled up by the first stirring shaft (13). The fibers fall along the inclined surface of the guide plate (47) onto the first stirring shaft (13), where they mix with the fibers at the front end of the feed bin (1) on the first stirring shaft (13). The mixed fibers are then picked up and mixed again by the second stirring shaft (14), and finally fall onto the feed curtain (6) at the front end of the second stirring shaft (14). At the same time, the second stirring shaft (14) drives its end limiting strip (34) to rotate synchronously. After the end of the limiting strip (34) contacts the inclined surface of the wedge block (33), it pushes the wedge block (33) to drive the scraper (30) away from the second stirring shaft (14). After the limiting strip (34) passes the wedge block (33), the scraper (30) will be subjected to the first stirring shaft (14). When the spring (32) pushes the scraper (30) back to its original position, the scraper (30) pushes the excess fiber on the feeding curtain (6) back to the bottom of the second stirring shaft (14). The airflow generated by the scraper (30) after its reset can slow down the flow speed of the brewing protein fiber. After the excess fiber enters the lower end of the second stirring shaft (14), it will be driven upward by its stirring rod and then stirred again by the stirring rod of the first stirring shaft (13). With the rotation of the first stirring shaft (13), it will be stirred and conveyed again.

After the second cylinder (35) has extended, the collection frame (36) will be completely inside the testing chamber (4). The fan (5) will draw the air and fibers in the opening device (3) into the testing chamber (4). The airflow passes through the ventilation groove (38), and all the fibers enter the collection frame (36). After the cylinder (35) extends for a period of time, it retracts. The collection frame (36) drives the ejector plate (42) to move upward together. After the second cylinder (35) retracts, the collection frame (36) returns to its initial state. The pressure sensing plate (37) will detect the weight of the collection frame (36) and its internal fibers. At the same time, the ejector plate (42) will be pushed downward by the elastic force of the second spring (49) to reset and push the fibers in the collection frame (36) downward.
