DETAILED DESCRIPTION

[0035] Example 1: Reference Figures 1-15 The top of the rotating shaft 5 is connected to the rotating shaft 5, and the outer wall of the rotating shaft 5 is provided with a plurality of squeezing blades 6. The top and bottom ends of the squeezing blades 6 are flush with the inner walls of the top and bottom ends of the net cylinder 4 respectively. Both sides of the squeezing blades 6 extend in the radial direction of the rotating shaft 5. The squeezing blades 6 can move around the outer wall of the rotating shaft 5. The top end of the rotating shaft 5 is connected to the rotating motor 7. The squeezing blades 6 are away from the outer wall of the rotating shaft 5 and slide in contact with the inner wall of the net cylinder 4. 6 is provided with an embedding groove at the top and bottom of one end away from the rotating shaft 5, and a magnetic sheet 11 is installed in the embedding groove. Electromagnetic blocks 10 are installed at both ends and the middle position of the extraction box 1. The electromagnetic blocks 10 and the magnetic sheet 11 are at the same height. When the sour jujube paste is filtered, the sour jujube paste is poured into the multiple chambers formed by the annularly distributed squeezing blades 6 in the mesh cylinder 4. The mesh cylinder 4, the rotating shaft 5 and the squeezing blades 6 are rotated at the same time to perform the basic extraction operation through centrifugal operation, so that the liquid passes through the mesh cylinder 4 into the extraction box 1 and is drawn out from the liquid outlet pipe 3; and in fact, during the rotation of the squeezing blades 6, when Figure 14As shown, when the extrusion blade 6 rotates to a position just facing the electromagnetic block 10, the extrusion blade 6 facing the electromagnetic block 10 extends toward the electromagnetic block 10, while the extrusion blade 6 at the adjacent position is at a position away from the electromagnetic block 10 and the magnetic attraction force received is small, so the extrusion blade 6 at the adjacent position is also in a normal position, and the multiple extrusion blades 6 are distributed in a nearly circular array; when the extrusion blade 6 continues to rotate, the extrusion blade 6 close to the electromagnetic block 10 is subjected to the magnetic attraction force and remains stationary or displaces a short distance relative to the electromagnetic block 10, causing the extrusion blade 6 to displace relative to the rotating shaft 5 until it reaches the position shown in FIG. Figure 15 As shown, the rear squeezing blades 6 rotate to be close to each other, so that the two adjacent squeezing blades 6 at this position squeeze the fruit puree in the middle position; thereby, the rotating shaft 5 drives the squeezing blades 6 to continuously move in a circular motion, so that the chambers between the plurality of adjacent squeezing blades 6 are continuously opened and closed to perform intermittent squeezing operations on the fruit puree, and the squeezing and centrifugation are combined to improve the filtrate anti-blocking effect; and by the opening and closing of the adjacent squeezing blades 6, the area of ​​the fruit puree in the same chamber that can adhere to the inner wall of the mesh cylinder 4 is continuously changed, so that the fruit puree attached to the inner wall of the mesh cylinder 4 is continuously overturned, thereby preventing the fruit puree from being constantly accumulated and affecting the filtrate operation, thereby improving the extraction effect of the fruit puree through the overall structural arrangement and use;

[0036] The squeezing strength of the adjacent squeezing blades 6 on the fruit puree is changed by adjusting the magnetic attraction of the electromagnetic block 10, and the squeezing operation during the rotation process is realized by the magnetic attraction, and the squeezing operation of the adjacent squeezing blades 6 is made movable to avoid damage to the quality of the fruit puree caused by excessive hard squeezing.

[0037] In the present invention, an arc-shaped limit groove 503 is provided at a position corresponding to the outer wall of the rotating shaft 5 and the extrusion blade 6. The limit groove 503 extends in the horizontal direction. A slider 8 is connected to the limit sliding in the limit groove 503. The slider 8 is fixed to the corresponding extrusion blade 6. Elastic strips 9 are connected between the two sides of the slider 8 and the inner wall of the limit groove 503, so that the extrusion blade 6 can be movable around the circumferential direction of the rotating shaft 5, thereby realizing the opening and closing extrusion operation of the adjacent extrusion blades 6 under the magnetic attraction of the electromagnetic block 10. It should be further explained that the slider 8 is provided with an inner block and an outer block, and the outer block is installed on the inner block Between the extrusion paddle 6, the cross-section of the inner block is larger than that of the outer block, and the opening position of the limit groove 503 can be detachably connected to the limit frame. The inner block is in sliding contact with the inside of the limit groove 503, and the outer block is in sliding contact with the inner wall of the limit frame, so as to facilitate the disassembly and installation of the extrusion paddle 6 and ensure the stability of the use of the extrusion paddle 6; two limit grooves 503 corresponding to the same extrusion paddle 6 are provided in the vertical direction to ensure the stability of the rotation setting of the extrusion paddle 6, and the limit grooves 503 distributed on the outside of the rotating shaft 5 are staggered, and the two limit grooves 503 in the same horizontal direction are not connected to each other.

The inner wall of the connecting groove 401 is in sliding contact with the outer wall of the rotating shaft 13, so that the net tube 4 can be directly placed in the extraction box 1, so that the top of the rotating shaft 13 extends into the connecting groove 401, and the top of the sleeve 12 is in contact with the bottom of the net tube 4, so that the net tube 4 is suspended and rotatably placed in the extraction box 1, which is convenient for directly taking out the net tube 4 after the extraction is completed to pour or transfer the fruit puree.

[0039] The top of the extraction box 1 is detachably connected to the box cover 2, and the rotating motor 7 is installed at the center position of the top of the box cover 2. The output shaft of the rotating motor 7 extends downward into the extraction box 1, and the output shaft of the rotating motor 7 is fixed with a card block 701 with a rectangular cross-section.

The movable mesh plate frame 14 is provided with an empty groove 141 on the side facing the outside of the mesh cylinder 4, and the top and bottom of the empty groove 141 are connected with springs 17. In the normal placement state, the movable mesh plate frame 14 is arranged between adjacent squeezing blades 6, and the inner side of the movable mesh plate frame 14 is flush with the inner wall of the mesh cylinder 4.

The electromagnetic block 10 is distributed in the middle position of the four sides of the extraction box 1. The four corners of the extraction box 1 are horizontally installed with a pressure rod 19. The pressure rod 19 is set to an arc structure with the middle position arched toward the net tube 4. The pressure rod 19 and the contact panel 18 are in the same horizontal direction. During use, Figure 14 In the first state, the extrusion blade 6 is facing the electromagnetic block 10. At this time, the two adjacent movable screen frames 14 are on both sides of the pressing rod 19 without contacting the pressing rod 19. At this time, the movable screen frame 14 extends outward under the action of the spring 17 and makes the inner side wall of the movable screen frame 14 fit with the inner wall of the screen cylinder 4; when it is rotated to Figure 15 In the second state shown, the movable screen frame 14 rotates to a position corresponding to the pressure rod 19, and the movable screen frame 14 is squeezed by the pressure rod 19 to protrude toward the inside of the screen cylinder 4, and the two squeezing blades 6 corresponding to the movable screen frame 14 protruding toward the inside of the screen cylinder 4 are opened, so that the originally accumulated fruit puree is separated toward both sides, so that the fruit puree attached to the inner wall of the screen cylinder 4 is turned over, so as to improve the filtration effect.
