DETAILED DESCRIPTION

[0028] The present invention is further described below in conjunction with specific embodiments.

[0029] Example 1

[0030] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the multi-stage pressing device for sesame oil production of this embodiment includes a housing 1, a limiting frame 16 is symmetrically arranged at the upper end of the interior of the housing 1, and a first pressing block 3 is arranged at the upper end between the two limiting frames 16, and the sesame oil placed between the pair of limiting frames 16 can be squeezed by the first pressing block 3 after being pushed;

[0031] Among them, a second support frame 17 is provided on one side of the outside of the two limiting frames 16, and the second support frame 17 is rotatably connected to the support of the limiting frame 16. The output of the motor drives the limiting frame 16 to rotate in the second support frame 17 to discharge the squeezed sesame oil;

[0032] In addition, in order to allow the two limiting frames 16 distributed in mirror image to rotate smoothly toward the lower end, second threaded rods 18 are provided on both sides of the interior of one of the second support frames 17, and the exterior of the second threaded rod 18 is threadedly matched with the penetration position of the second support frame 17, and one end of the second threaded rod 18 is rotatably connected to the other second support frame 17. Through the restriction of the second support frame 17 and the housing 1, the two second threaded rods 18 rotate simultaneously, and the spacing between the two limiting frames 16 can be adjusted;

[0033] In order to facilitate efficient secondary pressing, Figure 2 , Figure 3 and Figure 7As shown, six fixing rods 11 are evenly distributed around the lower end of the second support frame 17, and the six fixing rods 11 are bent outward toward one end of the limiting frame 16, and the bent end can be convenient for receiving the pressed sesame seeds dropped from the upper end. The lower ends of the six limiting frames 16 are welded and fixed by the second transmission sheet 10, and a connecting block 12 is provided on one side of the outside of the second transmission sheet 10, and the outside of the connecting block 12 is connected to a slot on one side of the outside of the second transmission sheet 10. The upper end of the connecting block 12 is provided with a first support frame 9, and the first support frame 9 is rotatably connected to the connecting block 12. After the second transmission sheet 10 is stuck on the upper end of the rotatable connecting block 12, an independent motor drives the connecting block 12 to rotate through the first support frame 9. During the rotation, the fixing rods 11 can be driven to adjust the angle, so as to facilitate secondary squeezing. The sesame seeds after squeezing can be adjusted by rotation, so as to avoid manual handling of sesame seeds, and facilitate multi-stage squeezing of sesame oil.

[0034] A support ring 23 is disposed on one side of the lower end of the connecting block 12, and a third hydraulic rod 22 is disposed around the lower end of the support ring 23. Figure 2 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, the lower end of the third hydraulic rod 22 is provided with a second oil storage tank 15, and the support ring 23 corresponds to the position of the fixed rod 11 after rotation. The support ring 23 can be pushed by the extension and contraction of the third hydraulic rod 22 to push and make the support ring 23 fit the second transmission plate 10. The support of the support ring 23 can prevent the second transmission plate 10 from being bent and damaged at the connection position with the connection block 12;

[0035] In addition, in order to wrap and cover the upper end of the fixing rod 11, as Figure 7 and Fig.10 As shown, a first transmission sheet 8 is transversely arranged at the upper end of the support ring 23, and a first hydraulic rod 7 for pushing is arranged on one side of the upper end of the first transmission sheet 8. The position of the first transmission sheet 8 can be adjusted by extending and retracting the first hydraulic rod 7, and the first transmission sheet 8 can be filled to the upper end of the surrounding fixed rods 11 by extending the first hydraulic rod 7;

[0036] In order to press the stacked sesame seeds to complete the pressing, Figure 7 and Fig.10 As shown, a second pressing block 24 is provided through the first transmission piece 8 at a position corresponding to the support ring 23, and a fourth hydraulic rod 25 is provided at the upper end of the second pressing block 24. The fourth hydraulic rod 25 can be extended to push the second pressing block 24 out of the first transmission piece 8, so that the second pressing block 24 squeezes the sesame seeds evenly distributed in the longitudinal direction, so that all the sesame oil drips into the second oil storage tank 15:

[0037] Among them, Figure 1 , Figure 2 and Figure 6 As shown, a second hydraulic rod 20 is arranged at the center position of the upper end of the first pressing block 3, and the first pressing block 3 can be pushed and the sesame placed inside the limiting frame 16 can be squeezed by the extension and retraction of the second hydraulic rod 20. An electric push rod 19 is arranged laterally on the upper end of the second hydraulic rod 20, and the position of the first pressing block 3 can be adjusted by the extension and retraction of the electric push rod 19. When the first pressing block 3 is not needed, the first pressing block 3 can be stored inside the housing 1 by the contraction of the electric push rod 19;

[0038] In order to store the sesame oil produced by the sesame seeds in the limiting frame 16, a first oil storage tank 13 is disposed laterally at the lower end of the limiting frame 16. Figure 2 and Figure 3 As shown, the first oil storage tank 13 is located between the fixing rod 11 and the limiting frame 16, one side of the outside of the first oil storage tank 13 is embedded in the shell 1 and is slidably connected to the inside of the shell 1, and a first threaded rod 14 is provided through the position where the first oil storage tank 13 is embedded in the shell 1, and the outside of the first threaded rod 14 is matched with the internal thread of the first oil storage tank 13, and the position of the first oil storage tank 13 can be adjusted laterally by rotating the first threaded rod 14;

[0039] In order to facilitate the transmission of the second threaded rod 18 and the first threaded rod 14, as shown in FIG. Figure 2 and Figure 4 As shown, one end of each of the two second threaded rods 18 is provided with a first handle 4, and one end of the first threaded rod 14 is provided with a second handle 5, and the protruding first handle 4 and second handle 5 can facilitate the rotation of the second threaded rod 18 and the first threaded rod 14;

[0040] Example 2

[0041] In order to facilitate the cleaning and removal of sesame seeds placed inside the fixing rod 11, a first dustproof plate 2 is provided on one side of the outer shell 1, and the first dustproof plate 2 is connected to a slot on one side of the outer shell 1. The first dustproof plate 2 is embedded in one side of the outer shell 1 and is fixed by bolts passing through it. Instead, the first dustproof plate 2 can be directly removed by removing the bolts.

[0042] like Figure 7 and Figure 8 As shown, bolts are provided between the outside of the connecting block 12 and the connecting position of the second transmission plate 10. When installing the second transmission plate 10, the second transmission plate 10 can be removed by removing the bolts through the connecting block 12.

[0043] Example 3

[0044] In order to facilitate the first pressing and squeezing of sesame seeds efficiently, Figure 1 , Figure 2 and Figure 6As shown, a discharge pipe 21 is provided at the upper end of the electric push rod 19, a second dustproof plate 6 is provided at the upper end of the outer shell 1, and a sesame storage device is provided between the second dustproof plate 6 and the discharge pipe 21. The sesame seeds to be squeezed are pre-placed between the second dustproof plate 6 and the discharge pipe 21. After the discharge pipe 21 is opened, the pre-stored sesame seeds can be directly discharged from the position of the discharge pipe 21.

[0045] Working principle: when using the device and squeezing sesame oil, the metal ring is placed in the groove inside the two limiting frames 16, and the oil filter paper is placed on the upper end of the metal ring. The sesame oil is spread flat on the oil filter paper. The weight of the sesame oil will cause the oil filter paper to sink into the metal ring, and the oil filter paper will be folded on the metal ring. The second hydraulic rod 20 and the first pressing block 3 are pushed out of the shell 1 by the extension of the electric push rod 19. The extension of the second hydraulic rod 20 can make the first pressing block 3 press the sesame oil wrapped in the oil filter paper in the metal ring, and the sesame oil will break through the oil filter paper and fall into the first oil storage tank 13. At the same time, the first pressing block 3 can also make the oil filter paper close to the sesame oil. Manually rotating the second handle 5 drives the first threaded rod 14 to rotate. The rotation of the first threaded rod 14 drives the first oil storage tank 13 to move horizontally after being restricted by the shell 1. Manually rotating the first handle 4 drives the second threaded rod 18 to rotate. The rotation of the second threaded rod 18 can produce relative movement with the interior of the second support frame 17. After the first support frame 17 is moved, so that a pair of limiting frames 16 move relative to each other, the motor suspended by the second support frame 17 is started, and the output shaft of the motor can drive the limiting frame 16 to rotate through the second support frame 17, so that the metal ring, oil filter paper and sesame oil fall between the surrounding fixed rods 11. As the first pressing block 3 is pressed one by one, multiple metal rings, oil filter papers and sesame oil can be arranged one by one on the second transmission plate 10. After enough metal rings, oil filter papers and sesame oil are accumulated, the motor at the upper end of the first support frame 9 drives the second transmission plate 10 and the upper fixed rod 11 to rotate through the connecting block 12. The extension and contraction of the first hydraulic rod 7 can push the first transmission plate 8, and the first transmission plate 8 will fill the upper end of the surrounding fixed rod 11. The extension and contraction of the fourth hydraulic rod 25 can push the second pressing block 24, so that the second pressing block 24 passes through the first transmission plate 8 to perform secondary squeezing on the stacked metal rings, oil filter papers and sesame oil, so that the sesame oil falls into the second oil storage tank 15.
