Description

Technical Field

[0001] The invention relates to the technical field of fruit juice extraction, in particular to a pomegranate juice extraction device. Background Art

[0002] Pomegranate is a berry. When it is ripe, the whole body can be used. The peel can be used as medicine, and the fruit can be eaten or squeezed into juice. It is rich in nutrients, containing a large amount of organic acids, sugars, proteins, fats, vitamins, and minerals such as calcium, phosphorus, and potassium. It can replenish the body's energy and calories, and has the effects of clearing heat, detoxifying, calming the liver, nourishing blood, activating blood circulation and stopping diarrhea. Pomegranate is not only rich in nutrients, but also the pomegranate leaves, pomegranate peel and pomegranate flowers can all be used as medicine.

[0003] However, since the edible part of the pomegranate is the outer seed coat of the seed, the hard inner seed coat cannot be eaten directly, which brings great inconvenience to eating fresh pomegranates. Pomegranate juice has become an important direction for the use of pomegranates, so pomegranate juicers have been widely used; When the existing pomegranate juicer is used, the pomegranate is cut into two halves with a fruit knife, and then the half pomegranate is placed in a concave bowl, and the convex bowl is moved downward by a driving device to squeeze the pomegranate, and the pomegranate juice is filtered by a filter net and then discharged from the juice outlet. Since the pomegranate needs to be cut in advance and the convex bowl needs to be manually driven to move downward to squeeze the pomegranate for juice extraction, the work efficiency is low, and it is easy to hurt the hands when manually cutting the pomegranate.

[0016] The following describes an embodiment of the present invention based on its overall structure.

[0017] A pomegranate juice extracting device, such as Figures 1 to 9 As shown, it includes a bottom frame 100, a pressing assembly for pressing pomegranates is provided on the top of the bottom frame 100, a take-in and put-out opening 101 is provided at the center of the top of the bottom frame 100, a four-frame 200 extending from the take-in and put-out opening 101 is provided inside the bottom frame 100, two sets of filter assemblies 300 are installed at the bottom ends of the four-frame 200, and a liquid frame 150 is provided inside the bottom frame 100 directly below the four-frame 200; The pressing assembly includes a top frame 110 fixed to the top of the bottom frame 100, a pressing plate 130 is installed directly below the top frame 110 and aligned with the four side frames 200, and an electric push rod 120 is installed on the top of the top frame 110 to drive the pressing plate 130 to rise and fall; The filter assembly 300 includes a driving shaft 310 rotatably arranged on the inner wall of the bottom frame 100, the driving shaft 310 is located at the bottom corner of the four-frame 200, two groups of filter frames 320 are fixed to the outer wall of the driving shaft 310 in the horizontal direction, two groups of baffles 330 are fixed to the outer wall of the driving shaft 310 in the vertical direction, and notches 210 are provided at the contact positions of the baffles 330 on both sides of the four-frame 200, and the outer wall of the driving shaft 310 is provided with fan blades 340 fixed to the inner wall of the bottom frame 100 near both ends, and the end surface of the fan blade 340 close to the filter frame 320 is provided with a fan-shaped groove 341, and multiple groups of hemispherical bodies 342 are fixed in the fan-shaped groove 341, and the rear surface of the bottom frame 100 is equipped with two groups of driving motors 350 for driving the driving shaft 310; A plurality of groups of partition bars 360 are slidingly provided in the filter frame 320, and a plurality of groups of semicircular grooves 361 are equidistantly provided on the side close to two adjacent groups of partition bars 360, and a clearance groove 363 connected to the semicircular groove 361 is provided inside the partition bar 360, and an arc bar 362 is fixed to the inner wall of the clearance groove 363 near the inner wall of the semicircular groove 361, and frame grooves 321 are provided at the front and rear ends of the filter frame 320, and a ball head rod 370 fixed to the end of the partition bar 360 is provided in the frame groove 321, and a restraining plate 322 fixed to the inner wall of the frame groove 321 is slidably sleeved on the outer wall of the ball head rod 370, and a spring 371 fixed to the restraining plate 322 is mounted on the outer wall of the ball head rod 370.

[0018] The telescopic end of the electric push rod 120 in the squeezing assembly pushes the pressing plate 130 down and goes deep into the four-frame frame 200 to complete the squeezing action on the pomegranate, so that the pomegranate juice flows from the gap between the partition bars 360 into the liquid frame 150 below. At this time, the electric push rod 120 can be controlled to raise the pressing plate 130 to be flush with the top of the bottom frame 100. At this time, the output end of the drive motor 350 will be controlled to rotate, and its driving shaft 310 will rotate 180 degrees accordingly, so that the filter frames 320 inside and outside the four-frame frame 200 are mutually adjusted, and the upper and lower baffles 330 will also be swapped. At this time, the pomegranates with squeezing can continue to be placed in the four-frame frame 200, and the electric push rod 120 can continue to be controlled to push the pressing plate 130 down to squeeze the pomegranate juice; The filter frame 320 and the multiple groups of partition bars 360 inside thereof are turned with the driving shaft 310, so that the tops thereof face downwards, and with the assistance of the centrifugal force when turning over, the pomegranate peels on the tops of the multiple groups of partition bars 360 will fall into the outer frame 410 below, and most of the pomegranate pulp will fall. As the filter frame 320 rotates, the ball head rods 370 at both ends of each group of partition bars 360 will move in an arc trajectory on the inner wall of the fan-shaped groove 341, and will contact the hemispherical body 342 on the way, so that the two adjacent groups of partition bars 360 will move in two directions, and the semi-circular grooves 342 opened on the adjacent sides of the two groups of partition bars 360 will move in two directions. The circular grooves 361 will gradually become misaligned, and the two groups of arc strips 362 will also be relatively close, so that the pomegranate peels located in the two groups of semicircular grooves 361 are compressed, and the outer diameter will be smaller than the inner walls of the two groups of semicircular grooves 361. Finally, due to the inertia of the filter frame 320 that has stopped rotating due to gravity, it will fall. At the same time, the spring 371 will make each group of partition strips 360 move back and forth in two directions, so that the pomegranate peels inside the two groups of semicircular grooves 361 will fall completely, which can facilitate the normal supply of pomegranate juice when the inner and outer filter frames 320 are swapped next time, and the high efficiency of pomegranate juice squeezing can be guaranteed every day.

[0019] Please refer to Figure 8 The top of the liquid frame 150 is open, a triangular frame is fixed at the top edge of the liquid frame 150, and a filter screen with a central protrusion is fixed inside the frame.

[0020] The triangular frame and the filter net are used to guide the pomegranate peels that fall from the contact position of the two groups of filter frames 320 accurately into the outer frame 410, and at the same time, the pomegranate juice can enter the liquid frame 150 through the filter net.

[0021] Please refer to Figure 4 The bottom corner of the notch 210 is provided with an arc opening 220 larger than the outer diameter of the driving shaft 310 , positioning blocks are fixed to the front and rear surfaces of the four frames 200 , and positioning block grooves are provided at the inner wall of the bottom frame 100 at positions corresponding to the positioning blocks.

[0022] The arc opening 220 can ensure that the driving shaft 310 is connected to the inner wall of the bottom frame 100 without constraints, and at the same time, the baffle 330 and the filter frame 320 can fully contact the four frames 200 to form a closed frame with the four frames 200 to achieve the pomegranate juice squeezing action.

[0023] Please refer to Figure 4 The multiple groups of hemispherical bodies 342 are distributed in a circular array with the center of the fan blade 340 as the base point, and the hemispherical bodies 342 on the end surfaces of the two groups of fan blades 340 are arranged in a staggered manner.

[0024] When the filter frame 320 rotates around the axis of the driving shaft 310, the two adjacent groups of partition bars 360 inside will move in two directions multiple times due to the staggered hemispheres 342, thereby cleaning the pomegranate peels in the two groups of semicircular grooves 361 of the adjacent partition bars 360, thereby ensuring that the filter net formed by the multiple groups of partition bars 360 is in a smooth state.

[0025] Please refer to Figure 8 and Fig. 9 A collecting assembly 400 is provided near the inner walls on both sides of the bottom frame 100, and a movable door 140 for removing the pomegranate peel in the collecting assembly 400 is provided on the side wall of the bottom frame 100; The collecting assembly 400 includes an outer frame 410 that is movably assembled with the bottom frame 100, a cone seat 420 is fixed to the inner wall of the outer frame 410, and a plurality of water-permeable holes are provided at the bottom of the cone seat 420. A discharge hole is reserved on the front and rear surfaces of the movable door 140 and near the bottom, and a sealing plug is threadedly connected to the discharge hole. Two groups of cone bars 430 are provided above the cone seat 420, and a top frame 440 is fixed to the top of the two groups of cone bars 430. An operating groove 102 is provided at the contact position between the front and rear inner walls of the bottom frame 100 and the top frame 440, and the operating groove 102 rotates A driven ring 450 is provided, and a base rod 480 is fixed to the driven ring 450 near the end surface of the top frame 440 and at an eccentric position, and a transverse frame 470 is sleeved on the outer wall of the base rod 480 to be slidably arranged with the operating groove 102, and a connecting arm 460 is fixed to the bottom of the transverse frame 470 and the top of the top frame 440, and a rotating rod is fixed at the center position of the driven ring 450 to be rotatably arranged with the inner wall of the operating groove 102, and the rotating rod and the driving shaft 310 are driven by a belt, and a belt groove connected to the operating groove 102 for belt drive is opened inside the bottom frame 100.

[0026] The fallen pomegranate peel will enter the space formed by the outer frame 410 and the cone seat 420. When the driving shaft 310 rotates, the driven ring 450 rotates synchronously through the transmission of the belt, and its end base rod 480 moves along the circular trajectory of the seat, so that the cross frame 470 will reciprocate up and down in the operating groove 102, so that the cone bar 430 is close to the cone seat 420 through the connecting arm 460, and the pomegranate peel is squeezed for the second time, so that the internal juice flows into the space of the outer frame 410 below the cone seat 420 through the discharge hole.

[0027] Please refer to Figure 8 A control screen is installed on the front surface of the bottom frame 100, and the control screen uses the existing technology to control the driving motor 350 and the electric push rod 120 to work.

[0028] When in use, the telescopic end of the electric push rod 120 in the squeezing assembly pushes the pressing plate 130 down and goes deep into the four-frame frame 200 to complete the squeezing action on the pomegranate, so that the pomegranate juice flows from the gap between the partition bars 360 into the liquid frame 150 below. At this time, the electric push rod 120 can be controlled to raise the pressing plate 130 to be flush with the top of the bottom frame 100. At this time, the output end of the drive motor 350 will be controlled to rotate, and its active shaft 310 will rotate 180 degrees accordingly, so that the filter frames 320 inside and outside the four-frame frame 200 are mutually adjusted, and the upper and lower baffles 330 will also be swapped. At this time, the pomegranates with squeezing can continue to be placed in the four-frame frame 200, and the electric push rod 120 can continue to be controlled to push the pressing plate 130 down to squeeze the pomegranate juice; The filter frame 320 and the multiple groups of partition bars 360 inside thereof are turned with the rotation of the driving shaft 310, so that the tops thereof face downwards, and with the assistance of the centrifugal force during the turning over, the pomegranate peels on the tops of the multiple groups of partition bars 360 will fall into the outer frame 410 below, and most of the pomegranate pulp will fall. As the filter frame 320 rotates, the ball head rods 370 at both ends of each group of partition bars 360 will move in an arc trajectory on the inner wall of the fan-shaped groove 341, and will contact the hemisphere 342 on the way, so that the two adjacent groups of partition bars 360 will move in two directions, and the semicircular grooves 361 opened on the adjacent sides of the two groups of partition bars 360 will gradually be misaligned, and the two groups of arcs will move in an arc trajectory. The strips 362 will also be relatively close, so that the pomegranate peel located in the two groups of semicircular grooves 361 is compressed, and the outer diameter will be smaller than the inner wall of the two groups of semicircular grooves 361, and finally the filter frame 320, which has stopped rotating due to gravity, will fall due to its inertia. At the same time, the spring 371 will make each group of partition strips 360 move back and forth in two directions, so that the pomegranate peel inside the two groups of semicircular grooves 361 will fall completely, which can facilitate the normal supply of pomegranate juice when the inner and outer filter frames 320 are swapped next time, and the high efficiency of pomegranate juice squeezing can be guaranteed every day. The parts not involved in the device are the same as the prior art or can be implemented by the prior art.
