Description

Technical Field

[0001] The invention belongs to the technical field of oil extraction, and in particular relates to an edible oil pressing instrument. Background Art

[0002] Plant seed oil is widely consumed. The traditional technology for extracting plant oil is to crush the seeds and then squeeze out the seed oil through a pressing process. The traditional oil pressing technology is to use a heavy object to hit the seeds so that the seeds can break and the oil can flow out. After the modern technology is improved, a cylinder is used to drive the oil to hit the oil so that the seed oil can flow out quickly.

[0003] However, the traditional method of using heavy objects to hit the seeds is inefficient and takes a long time to extract oil, making it unsuitable for industrial applications.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] like Figures 1 to 4As shown, an edible oil pressing instrument comprises a hollow fixed column 1, a linear drive motor, a receiving frame 23 for accommodating seed residue, a pressing device and a surrounding pushing device for pushing the seed residue to the pressing device; the pressing device comprises a sliding column 11, a transmission rod 13, a slide rail frame 14, a slide rail block 16, an elastic member 15, a connecting rod 17 and a first pressing push plate 19; the sliding column 11 is slidably arranged in the hollow part of the fixed column 1, and the output end of the linear drive motor is fixed to the upper end of the sliding column 11; the slide rail frame 14 is fixedly arranged on the side wall of the fixed column 1, and a slide groove is arranged on the slide rail frame 14, and the slide rail block 16 is slidably arranged in the slide groove, and the slide rail block 16 is arranged toward one end of the fixed column 1 There is a positioning groove; one end of the transmission rod 13 is rotatably connected to the sliding column 11, and the other end slides through the positioning groove; the elastic member 15 is arranged in the slide groove, and one end of the elastic member 15 is fixed to the slide rail block 16, and the other end is fixed to the groove wall of the slide groove close to the sliding column 11; one end of the connecting rod 17 is fixed to the slide rail block 16, and the other end is fixed to the first pressing push plate 19; the accommodating frame 23 is fixed to the end of the slide rail frame 14 facing away from the fixed column 1, and is located below the first pressing push plate 19, and the accommodating frame 23 is provided with a second pressing push plate 231, and the position of the second pressing push plate 231 corresponds to the position of the first pressing push plate 19; the slide rail block 16 is transmission-connected to the surrounding push device.

[0025] like Figure 2 As shown, the pressing device further comprises a first fixed seat 12 , which is fixedly arranged at the side end of the sliding column 11 . Accordingly, a through groove is correspondingly arranged at the side end of the fixed column 1 , and the transmission rod 13 is rotatably connected to the first fixed seat 12 .

[0026] like Figure 2 As shown, the first pressing push plate 19 is arc-shaped, and correspondingly, the second pressing push plate 231 is also arc-shaped.

[0027] Among them, by setting the pressing device, the seeds in different parts of the containing frame can be repeatedly pushed and squeezed to make the oil yield higher. The specific working principle is as follows (with Figure 2 For example):

[0028] When the linear drive motor drives the sliding column 11 to move downward, the sliding column 11 drives the end of the transmission rod 13 to move downward, so that the end of the transmission rod 13 facing away from the sliding column 11 moves obliquely downward. Since the transmission rod 13 and the slide block 16 are in contact, the horizontal force of the oblique downward movement of the transmission rod 13 will push the slide block 16 to move leftward in the slide groove. As a result, the first pressing push plate moves leftward until it contacts the second pressing push plate 231. Since the seeds are placed in the receiving frame 23, and the first pressing push plate 19 and the second pressing push plate 231 are both located in the receiving frame 23, the seeds will be squeezed between the first pressing push plate 19 and the second pressing push plate 231, so that after the seeds are broken, the oil slowly flows out.

[0029] like Figure 3 As shown, the surrounding pushing device includes a first transmission wheel 20, a second transmission wheel 21, a transmission belt 210, a surrounding pushing plate 220 and a connecting rod 22; the side end of the slide rail frame 14 is provided with a through groove, the side end of the slide rail block 16 is provided with a first tooth portion, the side end of the first transmission wheel 20 is provided with a second tooth portion meshing with the first tooth portion for transmission, and the first transmission wheel 20 and the slide rail block 16 are meshingly connected for transmission; the first transmission wheel 20 and the second transmission wheel 21 are synchronously connected through the transmission belt 210; one end of the connecting rod 22 is fixed to the side end of the second transmission wheel 21, and the other end is fixed to the surrounding pushing plate 220.

[0030] In the figure: 1, fixed column, 11, sliding column, 12, first fixed seat, 13, transmission rod, 14, slide rail frame, 15, elastic member, 16, slide rail block, 17, connecting rod, 19, first pressing push plate, 20, first transmission wheel, 21, second transmission wheel, 210, transmission belt, 22, connecting rod, 220, surrounding push plate, 23, containing frame, 231, second pressing push plate, 25, first connecting block, 26, second connecting block, 27, oil filter box, 28, soft connecting pipe, 29, oil receiving hopper.

[0031] In this case, taking the downward movement of the sliding column 11 as an example, the slide rail block 16 moves to the left, so that the first transmission wheel 20 meshing therewith also rotates. Since the first transmission wheel 20 and the second transmission wheel 21 are synchronously connected and transmitted through the transmission belt 210, when the second transmission wheel 21 rotates counterclockwise, it drives the connecting rod to move toward the side facing away from the slide rail frame 14, thereby driving the surrounding push plate to move toward the side away from the first squeezing push plate 19. The advantage of this arrangement is that when the first squeezing push plate 19 and the second squeezing push plate 231 squeeze the seeds, some seeds will be exposed from the gap between the first squeezing push plate 19 and the second squeezing push plate 231 under pressure, and the moving away of the surrounding push plate is to leave space to enclose more seeds. When the sliding column 11 moves upward, the surrounding push plate moves toward the side of the first squeezing push plate 19, and the seeds can be pushed to the space between the first squeezing push plate 19 and the second squeezing push plate 231 to facilitate squeezing again. At the same time, when the surrounding push plate pushes the seeds, it will actually loosen the seeds and seed particles, which is equivalent to turning the seeds slightly so that the seeds that are not directly subjected to force can face the pressure head-on, thereby increasing the oil yield.

[0032] At the same time, by Figure 2 or Figure 3 It can be seen that the purpose of the transmission setting of the first transmission wheel 20 and the second transmission wheel 21 is: if the connecting rod 22 is directly connected to the first transmission wheel 20, the rotation angle of the connecting rod 22 is too large, while in fact the connecting rod 22 only needs to rotate about 30 to 60 degrees. Therefore, by setting a second transmission wheel 21 with a larger diameter to be connected to the connecting rod 22, the rotation angle of the connecting rod 22 can be controlled, which should also be within the protection scope of this case.

[0033] In this embodiment, the surrounding pushing device also includes a second fixed seat and a third fixed seat, both of which are fixedly arranged on the side ends of the slide rail frame 14, the first transmission wheel 20 is rotatably connected to the second fixed seat, and the second transmission wheel 21 is rotatably connected to the third fixed seat.

[0034] like Figure 3 As shown, it is characterized in that the surrounding and pushing device further includes a first connecting block 25 made of elastic material, one end of the first connecting block 25 is fixed to the first pressing push plate 19, and the other end is fixed to the inner end of the surrounding push plate 220. The provision of the first connecting block 25 can prevent the seeds from leaking from the gap between the first pressing push plate 19 and the surrounding push plate 220 to the receiving frame 23 when being squeezed, which will affect the surrounding and pushing effect of the surrounding push plate 220. By providing the first connecting block 25, more seeds can be enclosed and pushed between the first pressing push plate 19 and the second pressing push plate.

[0035] like Figure 2As shown, the surrounding push device further includes a second connection block 26 made of elastic material, and the number of surrounding push plates 220 is two, and the two ends of the second connection block 26 are respectively fixed to the free ends of the two surrounding push plates 220. The function of the second connection block 26 is the same as that of the first connection block 25, which is to prevent the seeds from leaking out of the gap between the two surrounding push plates 220 after being subjected to force.

[0036] like Figure 3 The bottom end of the receiving frame 23 is provided with a through hole 230 for oil to flow down.

[0037] Among them, the edible oil pressing instrument also includes an oscillating filtering device, which includes an oil filter box 27 and a soft connecting tube 28; the oil filter box 27 is correspondingly arranged below the through hole 230, one end of the soft connecting tube 28 is fixed to the lower end of the containing frame 23, and the other end is fixed to the upper end of the oil filter box 27; the end of the transmission rod 13 facing away from the sliding column 11 is fixed to the side end of the oil filter box 27.

[0038] When the oil filter box 27 is shaking, it can be prevented that part of the seed powder blocks the through hole 230 and affects the use of the machine. Therefore, when the sliding column 11 moves, the power is synchronously transmitted to the oil filter box 27 by the oil transmission rod 13, and shaking is achieved at the same time.

[0039] In this embodiment, an oil receiving hopper 29 is fixedly connected to the periphery of the fixed column 1 .

[0040] Although embodiments of the present invention have been shown and described (see the above detailed description for details), it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
