[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4, the present utility model provides a technical solution: a double - screw press for extracting juice from fruits and vegetables. It includes a pressing assembly 1. On the side of the pressing assembly 1, a collection assembly 2 is fixedly connected. The pressing assembly 1 includes a housing 11. Inside one end of the housing 11, a feeding screw 12 is rotatably connected. On one side of the feeding screw 12, a second feeding screw 13 is movably connected. The feeding screw 12 and the second feeding screw 13 can rotate alternately to initially squeeze the incoming fruits and vegetables and convey them to one end of the squeezing screw blade 16 and the second squeezing screw blade 18. At the top of the feeding screw 12 and the second feeding screw 13, the second squeezing screw blade 18 and the squeezing screw blade 16 are fixedly connected. The distance between the screw blades of the second squeezing screw blade 18 and the squeezing screw blade 16 becomes smaller and smaller, which can fully press the incoming fruits and vegetables. A through - hole 15 is opened in the middle of the housing 11. On the side of the through - hole 15, a filter screen 14 is fixedly connected. After being pressed, the fruit and vegetable juice is collected by an external container through the juice collection plate 19 under the filtering action of the filter screen 14. At the other end of the housing 11, a fixing plate 17 protrudes. The fixing plate 17 is used to fix the feeding screw 12, the second feeding screw 13, the squeezing screw blade 16, and the second squeezing screw blade 18 inside the housing 11. Holes are opened above the feeding screw 12 and the second feeding screw 13, and a feeding port 110 is fixedly connected. The feeding screw 12 and the second feeding screw 13 are arranged alternately, the distance between the screw blades of the squeezing screw blade 16 and the second squeezing screw blade 18 gradually decreases, and a plurality of small holes are opened on the surface of the filter screen 14. A motor is provided at one end of the housing 11. The output end of the motor penetrates the side of the housing 11 and is fixedly connected to the feeding screw 12 and the second feeding screw 13 on the inner wall of the housing 11.

[0023] Please refer to Figures 1-4, the collection component 2 includes a slag collection bucket 21. One end of the slag collection bucket 21 is fixedly connected to a baffle 22. The end of the baffle 22 that is not connected to the inner wall of the slag collection bucket 21 gradually approaches inside the slag collection bucket 21, enabling the fruit and vegetable residues entering the interior to be stuck inside and preventing them from re-entering the interior of the filter screen 14. The other end of the slag collection bucket 21 is fixedly connected to a pressure spring 24. The top of the pressure spring 24 is fixedly connected to a pressing plate 23. The side of the housing 11 is fixedly connected to the slag collection bucket 21. A slag bucket rear cover 25 is provided on the side of the slag collection bucket 21. A pressure sensor is provided on the surface of the slag bucket rear cover 25. When it detects that the force exerted by the fruit and vegetable residues on the pressure spring 24 reaches a certain value, an alarm signal is emitted, and the slag bucket rear cover 25 can be opened to collect the fruit and vegetable residues, enabling the interior of the slag collection bucket 21 to continue collecting fruit and vegetable residues. The pressure sensor provided on the surface of the slag bucket rear cover 25 is a device or apparatus that can sense pressure signals and convert the pressure signals into usable output electrical signals according to certain rules. Utilizing the piezoelectric effect of some dielectric materials, it can convert mechanical energy into electrical energy or electrical energy into mechanical energy. It is usually composed of a pressure-sensitive element and a signal processing unit. A juice collection plate 19 is provided below the filter screen 14. One end of the juice collection plate 19 slopes downward. One end of the baffle 22 gradually approaches inside the slag collection bucket 21. Multiple grooves are provided on the surface of the pressing plate 23. The outside of the pressing plate 23 fits against the inner wall of the slag collection bucket 21.

[0024] When in use, when it is necessary to press fruits and vegetables, the feeding screw 12 and the second feeding screw 13 provided at one end of the housing 11 can initially squeeze the fruits and vegetables that enter the interior through the feeding port 110, and at the same time convey them to the interior of the extrusion screw blade 16 and the second extrusion screw blade 18 at the other end. Since the distance between the screw blades of the extrusion screw blade 16 and the second extrusion screw blade 18 becomes smaller and smaller, the fruits and vegetables conveyed can be fully pressed. After pressing, the juice enters the surface of the juice collection plate 19 through the filter screen 14 and is collected externally. The small holes provided on the surface of the filter screen 14 can separate the residues after pressing from the juice, improving the product quality. When it is necessary to collect the fruit and vegetable residues, through the baffle 22 provided at one end of the slag collection bucket 21, since the slag collection bucket 21 is fixedly connected to one end of the housing 11, the fruit and vegetable residues after being pressed by the extrusion screw blade 16 and the second extrusion screw blade 18 will be conveyed into the interior of the slag collection bucket 21 under the continuous rolling of the extrusion screw blade 16 and the second extrusion screw blade 18. The end of the baffle 22 that is not fixed to the slag collection bucket 21 gradually approaches inside the slag collection bucket 21. When the fruit and vegetable residues enter the interior of the slag collection bucket 21, they will not re-enter the interior of the filter screen 14 under the blocking action of the baffle 22. The fruit and vegetable residues that enter the slag collection bucket 21 will gradually squeeze the pressing plate 23. When the pressure of the pressure spring 24 approaches a certain value, it indicates that the interior of the slag collection bucket 21 is already full of fruit and vegetable residues, and the residues are collected by opening the slag bucket rear cover 25.
