The fruit oil, the oil cake and the oil cake mixture fall on the filter screen 41, the fruit oil enters the oil collecting cavity 4 through the filter screen 41, and at the moment, the fruit oil on the oil cake and the oil cake mixture can also seep into the oil collecting cavity 4, so that the fruit oil is collected. The two press rolls and the fruit oil on the side wall of the inner cavity of the case 1 drop on the guide arm 12 and flow to the filter screen 41 along the guide arm 12, so that the fruit oil is prevented from directly dropping in the feeding channel 14 along the side wall of the inner cavity of the case 1. The oil cake and the oil cake mixture slide down into the feeding channel 14 from the two side arms of the filter screen 41 under the action of self gravity.

Because the first connecting rod 33 is hinged to the first pressing roller 21 and the first sliding block 32, when the first pressing roller 21 rotates, the connecting end of the first connecting rod 33 and the first pressing roller 21 can be linked with the first pressing roller 21, and the first sliding block 32 can pull the first sliding block 32 to slide up and down on the first sliding rod 31 due to the limit of the first sliding rod 31; because the first slider 32 is further hinged with the two second connecting rods 53, the other end of each second connecting rod 53 is hinged with the second slider 52, and the second slider 52 is slidably connected to the second sliding rod 51, when the first slider 52 slides upwards, the second connecting rod 53 is pulled upwards, the second slider 52 slides on the second sliding rod 51 along with the second connecting rod 53 and is lifted upwards, and the two second sliders 52 move to the vault position of the filter screen 41; when the first slide block 32 slides downwards, the second connecting rod 53 moves downwards, and the second slide block 52 slides downwards on the second slide rod 51, and cleans the oil cake and the oil cake mixture remained in the meshes of the filter screen 41, so as to ensure the cleanliness of the filter screen 41, and the fruit oil filtering effect is not affected. Meanwhile, only the motor driving the first press roller 21 is needed, power is provided for the first press roller 21, the cleaning brush of the second sliding block 52 can be linked to clean the filter screen 41 (and the second press roller 22 is linked through a belt), multiple purposes are achieved through one power device, the cost is reduced, and the efficiency is improved.

The oil cake and the oil cake mixture slide down into the secondary pressing cavity 15 through the feeding channel 14, and the hydraulic cylinder periodically pushes and recovers the pressing plate 61, so that the space in the secondary pressing cavity 15 is changed. When the pressing plate 15 is pushed by the hydraulic cylinder to compress the space of the secondary pressing cavity 15, the mixture of the oil cake and the oil cake is extruded, the mixture of the oil cake and the oil cake abuts against the partition plate 71, the partition plate 71 slides in the case 1 and abuts against the first air bag 72, air of the first air bag 72 is introduced into the second air bag 75 through the air supply pipeline 74, the second air bag 75 expands to push the baffle plate 73 to enter the opening part of the secondary pressing cavity 15, the hydraulic cylinder continuously pushes and pushes the pressing plate 61 to a preset acting force threshold value until the baffle plate 73 completely shields the opening part of the secondary pressing cavity 15, and then the mixture of the oil cake and the oil cake in the feeding channel 14 cannot enter the secondary pressing cavity 15 again, and meanwhile, a closed space is provided for secondary pressing.

When the oil cake and the oil cake mixture are pressed in the secondary pressing cavity 15, the fruit oil at the pressed position enters the oil collecting cylinder 82 through the oil collecting pipe 81, so that the fruit oil is collected. It should be noted that when the oil cake and the oil cake mixture are squeezed again, the squeezing partition plate 71 enters the side boss 13, so the present embodiment further defines that a plurality of oil collecting pipes are also arranged on the cavity walls of the inner cavities of the machine cases 1 on both sides of the first air bag 72, so as to facilitate the collection of fruit oil. And after the secondary pressing of the oil cake and the oil cake mixture is finished, opening the discharge port 16 and discharging the oil cake.

Then, the discharge port 16 is closed, and the hydraulic cylinder returns, so that the oil cake and the oil cake mixture are prevented from entering between the partition plate 71 and the hydraulic cylinder because the baffle plate 73 is positioned on the upper side of the partition plate 71, and the normal use cannot be influenced; the pressure spring retracts due to the elasticity of the pressure spring, the baffle plate 73 is pulled back to the boss 13, the second air bag 75 is pressed, air in the second air bag 75 is led back to the first air bag 72 through the air supply pipeline 74, and the first air bag 72 pushes the partition plate 71 to reset. At this time, the secondary pressing cavity 15 leaves a space, and the oil cake mixture in the feeding channel 14 continue to be introduced into the secondary pressing cavity 15, so that feeding, secondary pressing and oil cake discharging are periodically performed.

This embodiment has carried out a lot of to green thorn kernel material and has squeezed, makes and squeezes the operation more abundant, and fruit oil output is bigger for it is higher to squeeze device unit efficiency, and the cost is reduced has improved production efficiency.
