[0031] Stirring mechanism, it includes: first driving part 8, stirring shaft 9 and stirring paddle 10, the stirring paddle 10 is located in stirring space and is connected to stirring shaft 9, and the stirring shaft 9 is connected to the output end of first driving part 8;
[0032] The feeding mechanism comprises a feeding pipe 62, a cutter 66, a baffle 69 and a second driving member 61, the feeding pipe 62 is arranged at the feeding port 11 and communicates with the stirring space, the cutter 66 is arranged at the first side of the feeding pipe 62, the baffle 69 is arranged at the second side of the feeding pipe 62, and the cutter 66 and the baffle 69 are connected to the output end of the second driving member 61.
[0033] The silkworm protein degumming equipment adds the silkworm protein to be degummed through the feeding port 11, drives the cutter 66 and the baffle 69 to move through the second driving member 61, cuts the silkworm protein through the cutter 66, removes the stop of the raw materials in the feeding pipe 62 through the movement of the baffle 69, makes the cut silkworm protein fall into the stirring space of the tank body 2 along the feeding pipe 62, and the silkworm protein raw material to be degummed is conveyed into the stirring space through the feeding port 11 and the feeding pipe 62, the degumming liquid is added through the water injection port 3, the degumming agent is added, the stirring shaft 9 is driven to rotate through the first driving, and the stirring paddle 10 is driven to rotate in the stirring space through the stirring shaft 9. The stirring paddle 10 stirs the silkworm protein raw material and the degumming liquid in the stirring space, so that they are fully mixed, and the degumming efficiency is improved.
[0034] The second driving member 61 is a linear driving member, and the feeding pipe 62 is respectively provided with a first avoiding hole and a second avoiding hole matched with the cutter 66 and the baffle 69. The linear driving member can be a cylinder, a hydraulic cylinder or a linear motor. In the embodiment, the cylinder is selected, and the cylinder has the advantages of simple structure, rapid action and low cost. The cross section of the feeding pipe 62 is circular or rectangular, and in the embodiment, the rectangular is selected. The first avoiding hole is arranged on the side of the feeding pipe 62 close to the cutter 66. The first avoiding hole is a rectangular through hole. The cutter 66 can be completely embedded in the first avoiding hole and cut off the channel in the feeding pipe 62 under the driving of the cylinder, so that the cutting operation of the silkworm protein is realized. The second avoiding hole is arranged on the side of the feeding pipe 62 close to the baffle 69. Since the output end of the cylinder is rigidly connected with the cutter 66 and the baffle 69 through the connecting member, the cutter 66 and the baffle 69 move synchronously along the linear direction.
[0035] The cutter 66 and the baffle 69 are driven by the second driving member 61 in the height direction and / or the horizontal direction. When the feeding pipe 62 is arranged at the side of the tank body 2, the cutter 66 and the baffle 69 are driven by the second driving member 61 in the height direction. When the feeding pipe 62 is arranged at the top of the tank body 2, the cutter 66 and the baffle 69 are driven by the second driving member 61 in the horizontal direction. In the embodiment, the feeding pipe 62 is arranged at the side of the tank body 2. During the downward movement of the cutter 66, the silk fibroin in the feeding pipe 62 is cut. At the same time, the baffle 69 also moves downward in the height direction, gradually removing the blockage of the channel of the feeding pipe 62. The cut silk fibroin falls into the stirring space of the tank body 2 under the action of gravity. After the feeding is completed, the second driving member 61 is driven in the direction, and the cutter 66 and the baffle 69 move upward in the height direction of the feeding pipe 62 to return to the initial position. The cutter 66 returns to above the feeding pipe 62, and the baffle 69 blocks the channel of the feeding pipe 62 again, waiting for the next feeding instruction, so as to complete a complete feeding cycle.
[0036] Referring to Figure 2 As shown, the feeding pipe 62 is arranged obliquely, and the end of the feeding pipe 62 gradually inclines downward to the direction close to the center of the tank body 2. During the feeding of the device, the silk fibroin to be degummed enters from the higher end of the feeding pipe 62. Due to the gradual downward inclination of the feeding pipe 62 to the direction close to the center of the tank body 2, the silk fibroin automatically slides to the lower end of the feeding pipe 62 under the action of gravity. The use of gravity makes the feeding process of the silk fibroin more smooth and efficient, reduces the problem of poor feeding caused by material accumulation or blockage, and ensures the stable operation of the silk fibroin degumming device.
[0037] Referring to Figure 2 As shown, the projection areas of the cutter 66 and the baffle 69 in the height direction do not coincide, the distance between the baffle 69 and the center of the tank body 2 is less than the distance between the cutter 66 and the center of the tank body 2, the cutter 66 and the baffle 69 are staggered, avoiding mutual interference, and the baffle 69 is closer to the tank body 2, and the cutter 66 is closer to the outside, so that the cutter 66 directly contacts the silk fibroin to be cut, improving the cutting efficiency.
[0038] Referring to Figure 1As shown, the tank body 2 is provided with a support 5, the feeding pipe 62 is arranged on the support 5 and is inclined downwardly to the direction close to the tank body 2 through the feeding port 11, the top end of the feeding pipe 62 is provided with an outwardly expanded feeding bin 63, the output end of the second driving member 61 is connected with the cutter 66 and the baffle 69 through the lifting frame 64, the movement path of the lifting frame 64 does not interfere with the feeding pipe 62, the supporting rod of the lifting frame is provided with a guide sleeve 65 connected with the support 5, thereby improving the movement stability of the lifting frame 64. The feeding pipe 62 is provided with a cushion block 67, and the cutting groove 68 is arranged in the cushion block 67 and is adapted to the cutter 66. The feeding pipe 62 is respectively provided with through holes adapted to the movement of the cutter 66 and the baffle 69.

In this embodiment, the inner wall of the feeding pipe 62 is embedded with the cushion block 67, the cutting groove 68 is arranged in the cushion block 67, thereby preventing the cutter 66 from hard collision with the inner wall of the feeding pipe 62 during the cutting of the silk protein, avoiding the feeding pipe 62 being damaged due to the scratching and impact of the cutter 66, thereby prolonging the service life of the feeding pipe 62 and ensuring the stable operation of the feeding mechanism.

The cut silk protein can be uniformly distributed on the discharging disc 1 and is stirred by the stirring paddle 10. The discharging disc 1 is sealingly connected to the inner wall of the tank body 2, thereby ensuring the sealing property of the stirring space and preventing the liquid and the material from leaking to other parts of the tank body 2 during the stirring. The material and the degumming liquid on the discharging disc 1 are gradually mixed with other substances in the stirring space under the stirring, thereby accelerating the degumming reaction.
