A filter box 24 is placed in the drawer box 22. A second filter screen 25 is provided at the lower end of the filter box 24. An oil outlet pipe 26 is also provided at the lower end of the placement frame 2. The oil outlet pipe 26 passes through the bottom plate 1. The specific implementation is as follows: after a proper amount of fried food is loaded into the filter bag, the filter bag is placed at the bottom of the placement frame 2. At this time, the filter bag is also in the rectangular frame formed by the telescopic plate 30 and the movable plate 32. When the interior of the rectangular frame formed by the telescopic plate 30 and the movable plate 32 is reduced by the first hydraulic rod 31, the telescopic plate 30 and the movable plate 32 can be used to squeeze the sides of the filter bag and the fried food therein. At the same time, the second hydraulic rod 41 drives the mounting plate 431 and the squeezing plate 430 to descend through the connecting rod 420 and the rotating rod 422, so that the bottom of the placement frame 2 cooperates with the mounting plate 431 and the squeezing plate 430 to twist and squeeze the two ends of the filter bag and the fried food therein, ensuring that the fried food inside The oil is fully squeezed out, and the squeezed oil is filtered through the filter groove at the bottom of the placement frame 2. The filter groove can filter the large pieces of fried food that fall down. At the same time, a second filter screen 25 is provided at the lower end of the filter box 24 to filter the squeezed oil for the second time. In addition, the extraction box 22 filters the oil squeezed out of the fried food for the third time through the first filter screen 23 provided at its lower end. The first filter screen 23 and the second filter screen 25 can filter the small particles of fried food in the squeezed oil to ensure that the oil discharged from the oil outlet pipe 26 is relatively clean. In addition, the filter box 24 is pulled out and the first filter screen 23 and the second filter screen 25 are cleaned at regular intervals to maintain the filtering effect of the first filter screen 23 and the second filter screen 25.

[0029] Working principle: Place the fried food to be squeezed in the filter bag, and then place the filter bag in a rectangular frame surrounded by two telescopic plates 30 and two movable plates 32. After the filter bag is placed, the extended ends of the two first hydraulic rods 31 respectively drive the two telescopic plates 30 to move in the rectangular frame surrounded by the two telescopic plates 30 and the two movable plates 32, so that the two telescopic plates 30 are close to each other and squeeze the filter bag and the fried food therein. At the same time, when the two telescopic plates 30 move close, the two movable plates 32 are driven to move close by the linkage mechanism 33. Specifically, when the extended ends of the two first hydraulic rods 31 respectively drive the two telescopic plates 30 to move close, the telescopic plates 30 synchronously pull the multiple steel wire ropes 332 connected to their two sides, and the steel wire ropes 332 are driven to move close. When the wire rope 332 is pulled, the reversing wheel 330 is used to reverse the wire rope 332, and the limiting wheel 331 is used to limit the position of the wire rope 332, so that the wire rope 332 pulls the movable plate 32 connected thereto to move synchronously and approach. In addition, when the movable plate 32 moves closer, it squeezes the telescopic plate 30, causing the telescopic plate 30 to contract, thereby causing the telescopic plate 30 and the movable plate 32 approaching each other to squeeze the filter bag and the fried food therein so that excess oil therein is filtered out by the filter bag. When squeezing excess oil from the fried food in the filter bag, the two telescopic plates 30 are first driven by the extended ends of the two first hydraulic rods 31 to move closer to squeeze the filter bag. At the same time, the telescopic plate 30 synchronously pulls the multiple wire ropes 332 connected thereto on both sides, so that The reversing wheel 330 and the limiting wheel 331 guide and limit the wire rope 332 so that the wire rope 332 pulls the movable plates 32 on both sides of the vertical plate 300 to move synchronously, so that the movable plates 32 approach each other and squeeze the filter bag, and when the movable plates 32 move close, the movable plates 32 squeeze the sliding plates 303, so that the sliding plates 303 drive the mounting rod 301 to squeeze the buffer spring 302 to slide into the vertical plate 300, so that the movable plates 32 squeeze the sliding plates 303 to gradually approach the vertical plate 300, and when the sliding plates 303 approach the vertical plate 300, they drive the baffle 304 to move synchronously, and when the baffle 304 moves on the vertical plate 300, it is guided and limited by the slider to prevent the baffle 304 from colliding with the vertical plate 3 00 is separated so that the baffle 304 can always provide squeezing force on the filter bag, avoiding the gap between the vertical plate 300 and the sliding plate 303 which makes it difficult for the telescopic plate 30 to squeeze the filter bag; after the fried food in the filter bag is squeezed, the two telescopic plates 30 are respectively driven by the extended ends of the two first hydraulic rods 31 to move and move away from the filter bag. At this time, the buffer spring 302 recovers and drives the mounting rod 301 to move toward the outside of the vertical plate 300, so that the mounting rod 301 drives the sliding plate 303 to move and reset in the direction away from the vertical plate 300, thereby causing the sliding plate 303 to squeeze the movable plate 32, causing the movable plate 32 to move in the opposite direction and reset, so that the filter bag and the fried food therein after squeezing are taken out;When the extended ends of the two first hydraulic rods 31 respectively drive the two vertical plates 300 to move close to the squeeze filter bag, the vertical plates 300 pull the movable plates 32 to move synchronously through the wire ropes 332. At this time, the movable plates 32 pull the return spring 21 to extend, so that the rectangular frame formed by the two telescopic plates 30 and the two movable plates 32 shrinks to squeeze the filter bag and the fried food therein. After the fried food is squeezed, the extended ends of the two first hydraulic rods 31 respectively drive the two vertical plates 300 to move and move away from the filter bag. At this time, the buffer spring 302 recovers and drives the mounting rod 301 to move toward the outside of the vertical plates 300, so that the mounting rod 301 drives the sliding plate 303 to move and reset in the direction away from the vertical plates 300, thereby causing the sliding plate 303 to squeeze the movable plate 32, causing the movable plate 32 to move in the opposite direction and reset. At the same time, the return spring 21 shortens, causing the movable plate 32 to return to its original position under the pressure of the return spring 21 The filter bag 30 and the fried food therein are squeezed by the movable plate 32, the vertical plate 300, the baffle plate 304 and the sliding plate 303. When the sides of the filter bag and the fried food therein are squeezed, the oil in the fried food overflows from the filter bag. At the same time, the movable plate 32, the vertical plate 300, the sliding plate 303 and the baffle plate 304 are provided with a plurality of through holes 320 inclined toward the bottom edge of the placement frame 2, which facilitate the conveying of the squeezed oil to the rear side of the movable plate 32, the vertical plate 300, the sliding plate 303 and the baffle plate 304, that is, to the space between the movable plate 32 and the placement frame 2 and between the telescopic plate 30 and the placement frame 2. The through holes 320 inclined toward the bottom edge of the placement frame 2 prevent the squeezed oil from soaking into the fried food again. When the first hydraulic rod 31 drives the telescopic plate 30 and the movable plate 32 to move closer to each other to squeeze the filter bag and the fried food therein from the side, the extended end of the second hydraulic rod 41 drives the rotating mechanism 42 and the pressing mechanism 43 to descend synchronously, so that the pressing mechanism 43 descends and squeezes the filter bag and the upper end of the fried food therein, so that the pressing mechanism 43 cooperates with the movable plate 32 and the telescopic plate 30 to squeeze the filter bag and the fried food therein, and when the second hydraulic cylinder drives the pressing mechanism 43 to continue to descend to squeeze the filter bag and the fried food therein, the rotating rod 422 can squeeze the compression spring 423 to move into the connecting rod 420, and at the same time, the rotating rod 422 rotates while moving under the action of the pin 424 and the spiral groove 421, that is, When the extended end of the second hydraulic rod 41 drives the connecting rod 420 to descend, the rotating rod 422 drives the squeezing mechanism 43 to rotate on the upper end of the filter bag and the fried food therein under the action of the pin 424 and the spiral groove 421, so that the squeezing mechanism 43 twists the filter bag and the fried food therein, so that the oil in the fried food is further squeezed out; and after the fried food is squeezed, the extended end of the second hydraulic rod 41 drives the connecting rod 420 to rise, so that the compression spring 423 is reset and squeezes the rotating rod 422, so that the rotating rod 422 drives the squeezing mechanism 43 to rotate in the opposite direction under the action of the pin 424 and the spiral groove 421 and twists the fried food again to squeeze it, so that the fried food is squeezed out of the oil again, ensuring that the fried food is The oil in the food is fully squeezed out; the second hydraulic rod 41 drives the mounting plate 431 to rotate and descend through the connecting rod 420 and the rotating rod 422, so that the mounting plate 431 drives the squeezing plate 430 to press tightly against the filter bag and the upper end of the fried food therein through the telescopic rod 432, so that the mounting plate 431 and the squeezing plate 430 squeeze the fried food, and when the second hydraulic rod 41 drives the connecting rod 420 and the rotating rod 422 to descend, the rotating rod 422 drives the mounting plate 431 to rotate through the cooperation between the pin 424 and the spiral groove 421, so that the mounting plate 431 drives the squeezing plate 430 to rotate on the upper end of the filter bag and the fried food therein through the telescopic rod 432, so that the mounting plate 431 and the squeezing plate 430 twists and squeezes the filter bag and the fried food therein, ensuring that the oil in the fried food is fully squeezed out; in addition, when the extended end of the second hydraulic rod 41 drives the mounting plate 431 and the squeezing plate 430 to rotate and squeeze the filter bag and the fried food therein through the connecting rod 420 and the rotating rod 422, the movable plate 32 and the telescopic plate 30 can squeeze the telescopic rod 432 through the squeezing plate 430, so that the rectangular frame surrounded by the movable plate 32 and the telescopic plate 30 can continue to shrink to squeeze the filter bag, ensuring that the movable plate 32 and the telescopic plate 30 continue to pressurize the filter bag, and at the same time, the upper and lower ends of the filter bag are squeezed through the mounting plate 431, the squeezing plate 430 and the bottom of the placement frame 2, thereby fully squeezing out the oil contained in the fried food;The mounting plate 431 drives the squeezing plate 430 to press the filter bag and the fried food therein through the telescopic rod 432. At the same time, the irregular horizontal bars 4300 on the squeezing plate 430 can squeeze the filter bag and the fried food therein, and the irregular horizontal bars 4300 can enable the squeezing plate 430 to press the filter bag tightly. When the rotating rod 422 drives the squeezing plate 430 to rotate through the mounting plate 431 and the telescopic rod 432, the squeezing plate 430 can drive the filter bag to twist through the irregular horizontal bars 4300, so that the excess oil in the fried food is squeezed out when the filter bag twists.

When the interior of the rectangular frame formed by the telescopic plate 30 and the movable plate 32 is reduced by the first hydraulic rod 31, the telescopic plate 30 and the movable plate 32 can be used to squeeze the sides of the filter bag and the fried food therein.
