Description

Technical Field

[0001] The invention relates to edible oil pressing equipment, in particular to an edible oil pressing machine. Background Art

[0002] The edible oil press is a mechanical device that extracts oil from raw materials. When used to provide edible oil, typical raw materials are nuts, seeds and algae. Depending on whether the raw materials are heat treated before pressing, pressing can be divided into hot pressing and cold pressing; depending on whether the residue is extracted and pressed again, it can be divided into secondary pressing and primary pressing.

[0003] Edible oil press generally includes base, oil tank, column, piston rod, barrel, cake plate, baffle and other parts. There is an oil cylinder fixed on the base, in which a piston rod is arranged. The upper part of the piston rod is connected with the cake plate as a whole. Before working, the raw materials need to be pre-pressed into round cakes and coated with cake rings. 20-40 round cakes are stacked between the cake plate and the top plate. The cakes are often separated by thin plates with holes to drive the piston rod upward to squeeze the cakes to extract oil.

[0004] A Chinese patent discloses an edible oil press, and the patent application number is CN201620697918.0, a fast hydraulic oil press, including a base, a column I, a column II and an upper top vertically installed above the base, a reversing valve is installed in front of the base, and the reversing valve is provided with an intermediate stop unloading gear; an oil cylinder is installed between the columns I and II, a barrel is installed above the cylinder, a ring groove is provided at the bottom of the barrel, an oil outlet nozzle is provided on the ring groove, a heating ring is sleeved around the barrel, and an oil outlet line is opened around the barrel; the upper top is sleeved on the top of the columns I and II, a handle is provided on one side of the upper top, and a rotating arm is installed on the top. The fast hydraulic oil press has a large bearing pressure, can be automatically pressurized, can perform secondary squeezing on residual materials, and has a high oil yield.

[0005] Although the machine has a high bearing pressure, can automatically increase the pressure, can perform secondary pressing on the residual material, and has a high oil yield, it does not solve the problem of pre-pressing the raw materials into round cakes before pressing them. This makes the pressing process of the raw materials more complicated, affecting the working efficiency of the press. At the same time, the pre-pressing of the raw materials into round cakes requires manual pressing, and the labor intensity of the workers is also relatively high, which increases the production cost.

[0006] For this reason, a edible oil pressing machine is proposed. Summary of the invention

[0007] The object of the present invention is to provide an edible oil press to solve the problems raised in the above background technology.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an edible oil press comprises a base, an oil tank is fixedly installed on one side of the outer surface of the base; a piston rod is fixedly connected to the middle position of the upper surface of the base; two columns are symmetrically fixedly connected to the upper surface of the base near the piston rod on both sides; an oil pan is fixedly installed at the middle position of the upper surface of the piston rod; an oil nozzle is fixedly connected to the outer circumferential surface of the oil pan on the side near the oil tank; a cake receiving plate is fixedly installed at the middle position of the upper surface of the oil pan; an upper top is fixedly connected to the upper end of the outer circumferential surface of the column, and a hole is opened through the middle position of the upper surface of the upper top; a barrel is arranged in the hole; a cover plate is arranged on the upper surface of the barrel; the barrel and the cover plate are fixedly connected to the upper surface of the upper top by bolts;

[0009] The barrel includes a barrel body, a central axis, a partition pressure plate, an oil leakage hole, a feed hole, a sealing ring, a protective airbag and a support ring; the lower surface of the upper top is fixedly connected to the barrel body by bolts; a central axis is arranged in the middle position of the inner cavity of the barrel body; the outer cylindrical surface of the central axis is linearly slidably connected with evenly distributed sealing rings; the outer cylindrical surfaces of the sealing rings are fixedly connected to the partition pressure plate; a feed hole is penetrated on one side of the upper surface of the partition pressure plate; evenly distributed oil leakage holes are penetrated on the upper surface of the partition pressure plate; a protective mechanism is sleeved on the outer cylindrical surface of the central axis near the lower position of the sealing ring, and the upper end of the protective mechanism is fixedly connected to the partition pressure plate; the lower end of the protective mechanism is fixedly connected to the support ring; the support ring is fixedly connected to the outer cylindrical surface of the central axis; the lower end of the inner cylindrical surface of the barrel body is fixedly connected to a baffle near the lower end surface of the barrel body.

[0010] During operation, the comparative patent does not solve the problem that the raw materials need to be pre-pressed into round cakes before being squeezed, which makes the squeezing process of the raw materials more complicated and affects the working efficiency of the squeezer. At the same time, the pre-pressing of the raw materials into round cakes requires manual pressing, and the labor intensity of the workers is also relatively large, which increases the production cost. Before squeezing the raw materials, the present invention opens the cover plate above the barrel, and pours the raw materials into the barrel through the feed port on the barrel. Under the action of the support ring, there is a large space between the partition pressing plates in the inner cavity of the barrel. The raw materials gradually enter between the partition pressing plates through the feed holes opened on the partition pressing plates until they are filled, and the cover plate is closed. The box drives the piston rod to start to push up, and the upward push of the piston rod drives the cake receiving plate and the bottom layer of separating pressure plates to start moving upward, layer by layer. Each layer of separating pressure plates starts to move upward driven by the piston rod to squeeze the raw materials. During the pressing process, the squeezed oil flows to the oil pan below through the oil leakage hole, and then flows into the container through the oil nozzle on the side wall of the oil pan. After the pressing is completed, the cover plate is opened, and the separating pressure plates and the residue in the barrel can be directly lifted out by lifting the center axis. The present invention solves the problem of pre-pressing the raw materials into round cakes by arranging the barrel, reduces the pressing process, and improves the working efficiency of the press. At the same time, there is no need for manual pressing of the round cakes, which increases the production cost.

[0011] Preferably, the sealing ring includes a sealing body, balls, a sealing gasket and a scraper; the outer cylindrical surface of the central shaft is linearly and slidingly connected to the evenly distributed sealing body; the upper end surface of the sealing body is fixedly connected to the scraper; the inner surface of the sealing body is provided with a groove, and evenly distributed balls are rollingly installed in the groove; a sealing gasket is arranged on the inner surface of the sealing body near the groove.

[0012] During operation, the space between each partition plate is filled with raw materials. Since the partition plate will move upward with the upper push of the piston rod, raw materials may enter the gap between the partition plate and the central axis during this process, and then block the gap. The blockage of the gap makes it difficult for the partition plate to move upward, resulting in insufficient squeezing of the raw materials above it by the partition plate, thereby affecting the working efficiency of the press. The present invention arranges a sealing ring, which includes a sealing body, a ball, a sealing gasket and a scraper. The upper end of the sealing body is fixedly connected to the scraper. During the upward movement of the partition plate, the scraper can peel off the raw materials adhered to the central axis. The inner surface of the sealing body is provided with a ball and a sealing gasket. The ball can convert the sliding connection of the partition plate on the central axis into a rolling connection, thereby reducing the friction between the partition plate and the central axis. The sealing gasket fully protects the sealing of the side wall of the partition plate. The present invention effectively prevents the raw material from entering the gap between the partition plate and the central axis by arranging the sealing ring, reduces the friction between the partition plate and the central axis, and protects the sealing of the side wall of the partition plate.

[0013] Preferably, the ball and the groove are arranged at the upper end position of the inner surface of the sealing body; and the sealing gasket is arranged on the inner surface of the sealing body below the ball.

[0014] During operation, the positional relationship between the ball disposed on the inner surface of the sealing ring and the sealing gasket may affect the movement promotion effect on the partition pressure plate and the sealing performance of the side wall. The present invention arranges the ball to be located above the sealing gasket. The ball is located above. Such a positional relationship enables, on the one hand, during the process of squeezing the raw materials, a small amount of squeezed oil will flow into the ball groove to lubricate the ball; on the other hand, the sealing gasket is located below the ball and the groove and can still play its role and play a sealing role.

[0015] Preferably, the protective mechanism includes a protective airbag and a limiting mechanism; the protective airbag is fixedly connected to the lower surface of the partition pressure plate, and the lower end of the protective airbag is fixedly connected to the support ring; two limiting mechanisms are symmetrically fixedly connected to the lower surface of the partition pressure plate near the inner side of the protective airbag.

[0016] During operation, when the edible oil press is working, too much raw material may be filled into the barrel. After pressing, the residue is compacted and inconvenient to unload. It takes a long time to unload, which affects the working efficiency of the press. The present invention arranges a protective mechanism. When the press presses the raw material, the protective airbag in the protective mechanism will be compressed, but a certain volume will still remain after compression. After pressing, the center shaft is taken out together with the partition plate, and the unloading is carried out by moving the partition plate. In this process, the protective airbag is stretched so that there is space in the middle of the residue to leak out, making the residue unloading operation more convenient.

[0017] Preferably, the limiting mechanism includes an outer sleeve, an inner sleeve rod and an inner sleeve ring; the lower surface of the partition pressure plate is symmetrically fixedly connected to the outer sleeve near the inner side of the airbag; the upper end surface of the support ring is fixedly connected to the inner sleeve rod at a position corresponding to the outer sleeve, and one end of the inner sleeve rod passes through the side wall of the outer sleeve and extends into the interior thereof; the end surface of one side of the inner sleeve rod that passes through the outer sleeve is fixedly connected to the inner ring.

[0018] During operation, when the raw materials are compressed, the scraper on the sealing ring may collide with the support ring due to the small amount of raw materials in the barrel and the large top depth of the piston rod, causing damage to the scraper and the protective airbag. The present invention prevents such phenomenon from occurring by arranging a limiting mechanism. When the piston rod presses the raw materials, the partition pressure plate moves upward with the top of the piston rod, driving the outer sleeve fixedly connected to the lower surface of the partition pressure plate to move upward. When the piston rod reaches a certain top depth, the lower surface of the inner cavity of the outer sleeve fits with the lower surface of the inner ring. The top depth of the piston rod at this time is its compression limit. The present invention solves the problem of excessive top depth of the piston rod, which may cause damage to the scraper and the protective airbag, by arranging a limiting mechanism.

[0019] Preferably, a first pole piece is provided on the lower surface of the inner ring; a second pole piece is provided on the lower surface of the inner cavity of the outer sleeve near the inner sleeve rod; a buzzer is embedded and installed on the lower surface of the outer sleeve near the inner sleeve rod; the first pole piece, the second pole piece and the buzzer are electrically connected to a power supply.

[0020] During operation, when the partition pressure plate is stretched, the limit mechanism may be directly damaged due to ignoring the compression limit. The present invention sets a buzzer, and a first pole piece is set on the lower surface of the inner ring, and a second pole piece is set on the lower surface of the inner cavity of the outer sleeve near the inner sleeve rod. When the depth of the piston rod top reaches the compression limit, the first pole piece and the second pole piece are in contact with each other, the buzzer circuit loop is connected, and the buzzer works to alarm, reminding the staff that the compression limit has been reached. The present invention sets a buzzer to prevent the limit mechanism from being damaged due to ignoring the compression limit.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The present invention sets a barrel. Before squeezing the raw materials, the cover plate above the barrel is opened, and the raw materials are poured into the barrel through the feed port on the barrel. Under the action of the support ring, there is a large space between the partition pressing plates in the inner cavity of the barrel. The raw materials gradually enter between the partition pressing plates through the feed holes provided on the partition pressing plates until they are filled. After the cover plate is closed, the oil tank drives the piston rod to start to push up, and the pushing up of the piston rod drives the cake receiving plate and the bottom layer of the partition pressing plate to start moving upward, layer by layer. Each layer of the partition pressing plates starts to move upward driven by the piston rod to squeeze the raw materials, which solves the problem of pre-pressing the raw materials into round cakes, reduces the squeezing process, and improves the working efficiency of the press. At the same time, there is no need to manually squeeze the round cakes, which increases the production cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] See also Figures 1 to 5 The present invention provides a technical solution for an edible oil press:

[0033] An edible oil press, such as Figure 1 to Figure 2 As shown, it includes a base 2, and an oil tank 1 is fixedly installed on one side of the outer surface of the base 2; a piston rod 4 is fixedly connected to the middle position of the upper surface of the base 2; two columns 3 are symmetrically fixedly connected to the upper surface of the base 2 near the piston rod 4 on both sides; an oil pan 5 is fixedly installed in the middle position of the upper surface of the piston rod 4; an oil nozzle 6 is fixedly connected to the outer cylindrical surface of the oil pan 5 near the oil tank 1; a cake plate 7 is fixedly installed in the middle position of the upper surface of the oil pan 5; an upper top 9 is fixedly connected to the upper end of the outer cylindrical surface of the column 3, and a hole is opened through the middle position of the upper surface of the upper top 9; a barrel 8 is arranged in the hole; a cover plate is arranged on the upper surface of the barrel 8; the barrel 8 and the cover plate are fixedly connected to the upper surface of the upper top 9 by bolts;

[0034] The barrel 8 includes a barrel body 81, a central axis 82, a partition pressure plate 83, an oil leakage hole 84, a feed hole 85, a sealing ring 86, a protective airbag 87 and a support ring 88; the lower surface of the upper top 9 is fixedly connected to the barrel body 81 by bolts; a central axis 82 is provided in the middle of the inner cavity of the barrel body 81; the outer circumferential surface of the central axis 82 is linearly slidably connected to uniformly distributed sealing rings 86; the outer circumferential surfaces of the sealing rings 86 are fixedly connected to the partition pressure plates 83; the upper surface of the partition pressure plates 83 is fixedly connected to the outer circumferential surface of the sealing rings 86; the upper surface of the partition pressure plates 83 is fixedly connected to the inner ... A feed hole 85 is formed through one side of the surface; evenly distributed oil leakage holes 84 are formed through the upper surface of the partition pressure plate 83; a protective mechanism 87 is sleeved on the outer cylindrical surface of the central shaft 82 near the lower position of the sealing ring 86, and the upper end of the protective mechanism 87 is fixedly connected to the partition pressure plate 83; a support ring 88 is fixedly connected to the lower end of the protective mechanism 87; the support ring 88 is fixedly connected to the outer cylindrical surface of the central shaft 82; a baffle is fixedly connected to the lower end of the inner cylindrical surface of the barrel body 81 near the lower end surface of the barrel body 81.

[0035] During operation, the comparative patent does not solve the problem that the raw materials need to be pre-pressed into round cakes before being squeezed, which makes the squeezing process of the raw materials more complicated and affects the working efficiency of the squeezer. At the same time, the raw materials need to be pre-pressed into round cakes manually, and the labor intensity of the workers is also relatively large, which increases the production cost. Before squeezing the raw materials, the present invention opens the cover plate above the barrel 8, and pours the raw materials into the barrel 8 through the feed port on the barrel 8. Under the action of the support ring 88, there is a large space between the partition plates 83 in the inner cavity of the barrel 8. The raw materials gradually enter between the partition plates 83 through the feed holes 85 opened on the partition plates 83 until they are filled, and the cover plate is closed. The oil tank 1 The piston rod 4 is driven to start to push up, and the upward push of the piston rod 4 drives the cake receiving plate 7 and the bottom layer of separating pressure plate 83 to start to move upward, layer by layer. Each layer of separating pressure plate 83 starts to move upward driven by the piston rod 4 to squeeze the raw material. During the pressing process, the squeezed oil flows to the oil pan 5 below through the oil leakage hole 84, and then flows into the container through the oil nozzle 6 on the side wall of the oil pan 5. After the pressing is completed, the cover plate is opened, and the separating pressure plate 83 and the residue in the barrel 8 can be directly lifted out by lifting the center axis 82. The present invention solves the problem of pre-pressing the raw materials into round cakes by setting the barrel 8, reduces the pressing process, and improves the working efficiency of the press. At the same time, there is no need for manual pressing of the round cakes, which increases the production cost.

[0036] As an embodiment of the present invention, Figure 3As shown, the sealing ring 86 includes a sealing body 861, balls 862, a sealing gasket 863 and a scraper 864; the outer cylindrical surface of the central shaft 82 is linearly and slidingly connected with the evenly distributed sealing body 861; the upper end surface of the sealing body 861 is fixedly connected with the scraper 864; the inner surface of the sealing body 861 is provided with a groove, and the evenly distributed balls 862 are rollingly installed in the groove; the inner surface of the sealing body 861 is provided with a sealing gasket 863 near the groove.

[0037] During operation, the space between the partition plates 83 is filled with raw materials. Since the partition plates 83 move upward with the piston rod 4, raw materials may enter the gap between the partition plates 83 and the central axis 82 during this process, thereby blocking the gap. The blockage of the gap makes it difficult for the partition plates 83 to move upward, resulting in insufficient squeezing of the raw materials above the partition plates 83, thereby affecting the working efficiency of the press. The present invention provides a sealing ring 86, which includes a sealing body 861, a ball 862, a sealing gasket 863 and a scraper 864. The upper end of the sealing body 861 is fixedly connected to the scraper 864, and the scraper 864 is in the partition During the upward movement of the pressure plate 83, the raw materials adhered to the central axis 82 can be peeled off. The inner surface of the sealing body 861 is provided with ball bearings 862 and sealing gaskets 863. The ball bearings 862 can transform the sliding connection of the partition pressure plate 83 on the central axis 82 into a rolling connection, thereby reducing the friction between the partition pressure plate 83 and the central axis 82. The sealing gasket 863 fully protects the sealing of the side wall of the partition pressure plate 83. The present invention effectively prevents the raw materials from entering the gap between the partition pressure plate 83 and the central axis 82 by providing a sealing ring 86, thereby reducing the friction between the partition pressure plate 83 and the central axis 82 and protecting the sealing of the side wall of the partition pressure plate 83.

[0038] As an embodiment of the present invention, Figure 3 As shown, the ball 862 and the groove are arranged at the upper end position of the inner surface of the sealing body 861; the sealing gasket 863 is arranged on the inner surface of the sealing body 861 below the ball 862.

[0039] During operation, the positional relationship between the ball 862 and the sealing gasket 863 provided on the inner surface of the sealing ring 86 may affect the movement promotion effect on the partition pressure plate 83 and the sealing performance of the side wall. The present invention arranges the ball 862 to be located above the sealing gasket 863. The ball 862 is located at the top. Such a positional relationship enables, on the one hand, during the process of squeezing the raw materials, a small amount of squeezed oil will flow into the ball groove to lubricate the ball 862; on the other hand, the sealing gasket 863 is located below the ball 862 and the groove and can still play its role and perform a sealing function.

[0040] As an embodiment of the present invention, Figure 4 As shown, the protective mechanism 87 includes a protective airbag 871 and a limiting mechanism 872; the lower surface of the partition pressure plate 83 is fixedly connected with the protective airbag 871, and the lower end of the protective airbag 871 is fixedly connected to the support ring 88; the lower surface of the partition pressure plate 83 is symmetrically fixedly connected with two limiting mechanisms 872 near the inner side of the protective airbag 871.

[0041] During operation, when the edible oil press is working, too much raw material may be filled into the barrel 8. After pressing, the residue is compacted and inconvenient to unload. It takes a long time to unload, which affects the working efficiency of the press. The present invention sets a protective mechanism 87. When the press presses the raw material, the protective airbag 871 in the protective mechanism 87 will be compressed, but a certain volume will still remain after compression. After pressing, the center shaft 82 is taken out together with the partition plate 83, and the unloading is carried out by moving the partition plate 83. During this process, the protective airbag 871 is stretched so that there is space in the middle of the residue to leak out, making the residue unloading operation more convenient.

[0042] As an embodiment of the present invention, Figure 5 As shown, the limiting mechanism 872 includes an outer sleeve 8721, an inner sleeve rod 8722, and an inner sleeve ring 8723; the lower surface of the partition pressure plate 83 is symmetrically fixedly connected with the outer sleeve 8721 at an inner position close to the airbag 871; the upper end surface of the support ring 88 is fixedly connected with the inner sleeve rod 8722 at a position corresponding to the outer sleeve 8721, and one end of the inner sleeve rod 8722 passes through the side wall of the outer sleeve 8721 and extends into the interior thereof; the end surface of one side of the inner sleeve rod 8722 that passes through the outer sleeve 8721 is fixedly connected with the inner sleeve ring 8723.

[0043] During operation, when the raw material is compressed, due to the small amount of raw material in the barrel 8 and the large top depth of the piston rod 4, the scraper 864 on the sealing ring 86 may collide with the support ring 88, causing damage to the scraper 864 and the protective airbag 871. The present invention prevents such a phenomenon from occurring by providing a limiting mechanism 872. When the piston rod 4 presses the raw material, the partition plate 83 moves upward with the top of the piston rod 4, driving the outer sleeve 8721 fixedly connected to the lower surface of the partition plate 83 to move upward. When the top of the piston rod 4 reaches a certain depth, the lower surface of the inner cavity of the outer sleeve 8721 fits with the lower surface of the inner ring 8723. At this time, the top depth of the piston rod 4 is its compression limit. The present invention solves the problem that the top depth of the piston rod 4 is too large, causing damage to the scraper 864 and the protective airbag 871, by providing a limiting mechanism 872.

[0044] As an embodiment of the present invention, Figure 5As shown, a first pole piece 8724 is provided on the lower surface of the inner ring 8723; a second pole piece 8725 is provided on the lower surface of the inner cavity of the outer sleeve 8721 near the inner sleeve rod 8722; a buzzer 8726 is embedded and installed on the lower surface of the outer sleeve 8721 near the inner sleeve rod 8722; the first pole piece 8724, the second pole piece 8725 and the buzzer 8726 are electrically connected to a power supply.

[0045] During operation, when the partition pressure plate 83 is stretched, the limiting mechanism 872 may be directly damaged due to ignoring the compression limit. The present invention sets a buzzer 8726, and a first pole piece 8724 is set on the lower surface of the inner ring 8723. A second pole piece 8725 is set on the lower surface of the inner cavity of the outer sleeve 8721 near the inner sleeve rod 8722. When the top depth of the piston rod 4 reaches the compression limit, the first pole piece 8724 and the second pole piece 8725 are in contact with each other, and the circuit loop of the buzzer 8726 is connected. The buzzer 8726 works to alarm, reminding the staff that the compression limit has been reached. The present invention sets a buzzer 8726 to prevent the limiting mechanism 872 from being damaged due to ignoring the compression limit.

[0046] Method of use: When the present invention is used, the raw material to be squeezed is first poured into the barrel 8 through the feed port at the upper end of the barrel 8. The raw material flows into the space between the partitioning plates 83 through the feed hole 85 in the barrel 8. When the barrel 8 is full of raw materials, the pouring is stopped, the cover is covered, and it is fixed by tightening the nut, and the piston rod 4 is driven to start pushing up for squeezing. During the squeezing process, the oil squeezed out of the raw material flows downward through the oil leakage hole 84, and a small part of it flows into the sealing ring 86 to lubricate the ball 862. The sealing gasket 863 in the sealing ring 86 and the protective airbag 871 in the protective mechanism are together At the same time, the sealing on the side of the partition pressure plate 83 is protected. The protective airbag 871 will be compressed with the upward push of the piston rod 4, leaving a certain volume. The squeezed oil will eventually fall into the oil pan 5, and then flow into the oil container through the oil nozzle 6 on the side wall of the oil pan 5; after squeezing, the piston rod 4 falls, the cover plate is opened, the central axis 82 together with the partition pressure plate 83 is pulled out of the barrel 8, the partition pressure plate 83 is stretched, and the protective airbag 871 is also stretched and part of the space is exposed, which is convenient for unloading. During the stretching process, the limit mechanism 872 will play a role to prevent excessive stretching and alarm when the stretching limit is reached.
