Description

Technical Field

[0001] The utility model relates to the technical field of edible oil, and specifically relates to a pressing device for edible oil production. Background Art

[0002] Edible oil, also known as "cooking oil", refers to animal or vegetable oils used in the process of making food. It is liquid at room temperature. Due to reasons such as raw material sources, processing techniques, and quality, common edible oils are mostly plant oils, including corn oil, rapeseed oil, peanut oil, hemp oil, corn oil, olive oil, camellia oil, palm oil, mustard oil, sunflower oil, soybean oil, sesame oil, linseed oil (flaxseed oil), grape seed oil, walnut oil, peony seed oil, etc. A pressing device is required in the process of processing raw materials into oil.

[0003] For example, the patent No. CN215620171U discloses a physical pressing device for edible oil production, which includes a pressing cylinder. The left and right sides of the top of the outer surface of the pressing cylinder are fixedly connected with support rods. A top plate is fixedly connected between the tops of the two support rods. A hydraulic rod is fixedly connected to the bottom of the top plate. The bottom end of the hydraulic rod is fixedly connected with a pressing plate. A filter plate is fixedly connected inside the pressing cylinder. Inside the pressing cylinder and below the filter plate, a guiding disc is fixedly connected through a connecting block. The top surface of the guiding disc protrudes upward. An oil outlet is opened at the bottom of the pressing cylinder. Through the setting of the upward-protruding guiding disc and the connecting block, the utility model can make the edible oil further flow downward from the edge of the guiding disc, leaving the fine particles on the top surface of the guiding disc, realizing the separation of the edible oil and the particles, reducing the process of further filtering the edible oil, and improving the work efficiency.

[0004] Based on the search of the patent number and the deficiencies found in the existing technology:

[0005] Although this physical pressing device for edible oil production realizes the separation of edible oil and particles, reduces the process of further filtering the edible oil, and improves the work efficiency, during use, since the pressing plate has a strong extrusion force on the raw materials during pressing, the raw materials will also be in close contact with the filter plate, resulting in some raw materials entering the through holes inside the filter plate and causing the filter plate to become blocked. And the filter plate is fixedly installed in the middle area of the inner wall of the pressing cylinder, so it is not convenient for the user to clean it. In addition, setting a box door on the pressing cylinder will cause a gap between the box door and the pressing cylinder, resulting in the outflow of edible oil, so the practicability is not high. Content of the Utility Model

[0006] To solve the problems raised in the above-mentioned background art, the purpose of the present utility model is to provide a pressing device for edible oil production, which has the advantage of being convenient for disassembling and cleaning the filter plate, and solves the problem that since the pressing plate has a strong squeezing force on the raw materials during pressing, the raw materials will also be in close contact with the filter plate, resulting in some raw materials entering the through holes inside the filter plate and causing blockage of the filter plate. The filter plate is fixedly installed in the middle area of the inner wall of the pressing cylinder, so it is not convenient for users to clean it. And setting a door on the pressing cylinder will cause a gap between the door and the pressing cylinder, resulting in the outflow of edible oil, so the practicability is not high.

[0007] To achieve the above purpose, the present utility model provides the following technical solutions: A pressing device for edible oil production, including a pressing cylinder, a support frame, a hydraulic rod, a pressing plate, support legs and a filter plate. The inner side of the support legs is fixedly connected to the surface of the pressing cylinder.

[0008] Preferably, the connecting mechanism includes a fixing cylinder. A connecting ring is movably connected to the bottom of the pressing plate. There are four connecting rings and they are evenly distributed in a ring shape. A connecting rod is fixedly connected to the inner wall of the connecting ring. The surface of the connecting rod is movably connected to the inner wall of the support spring. The other end of the connecting rod penetrates through the fixing cylinder and extends to the bottom of the fixing cylinder. The connecting rod is movably connected to the fixing cylinder. One end of the support spring close to the pressing plate is fixedly connected to the bottom of the connecting ring. The other end of the support spring is fixedly connected to the bottom of the inner wall of the fixing cylinder.

[0009] Preferably, the limiting component includes a through hole. The diameter of the connecting ring is the same as that of the through hole. A limiting ring is fixedly connected to the bottom of the surface of the connecting rod. The top of the limiting ring is in contact with the bottom of the fixing cylinder.

[0010] Preferably, a single-headed screw is fixedly connected to the end of the connecting rod away from the fixing cylinder. The other end of the single-headed screw penetrates through the filter plate and is threadedly connected with a button cap. The single-headed screw is movably connected to the filter plate.

When the pressing plate moves upward, the support spring can push the filter plate back to its original position, solving the problem that when the pressing plate presses the raw materials, there will be a strong extrusion force on the raw materials, so the raw materials will also be in close contact with the filter plate, resulting in some raw materials entering the through holes inside the filter plate and causing blockage of the filter plate. Since the filter plate is fixedly installed in the middle layer area of the inner wall of the pressing cylinder, it is not convenient for the user to clean it. And by setting a box door on the pressing cylinder, there will be a gap between the box door and the pressing cylinder, resulting in the outflow of edible oil, so the practicality is not high, achieving the effect of facilitating the disassembly and cleaning of the filter plate.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figures 1 to 4 shown, a pressing device for edible oil production provided by the present utility model includes a pressing cylinder 1, a support frame 2, a hydraulic rod 3, a pressing plate 4, a support leg 5 and a filter plate 6. The inner side of the support leg 5 is fixedly connected to the surface of the pressing cylinder 1. The inner side of the support frame 2 is fixedly connected to the top of the surface of the pressing cylinder 1. The hydraulic rod 3 is fixedly installed at the top of the inner wall of the support frame 2. The pressing plate 4 is fixedly installed at the piston end of the hydraulic rod 3.

The surface of the fixing ring 7 is fixedly connected to the inner wall of the pressing cylinder 1. Four support springs 8 are arranged at the bottom of the pressing plate 4. The four support springs 8 are evenly distributed in a ring at equal intervals. Four connecting mechanisms 9 are fixedly connected to the bottom of the fixing ring 7. Four limiting components 10 are opened at the top of the fixing ring 7.

[0025] Refer to Figure 2, the connecting mechanism 9 includes a fixed cylinder 91. A connecting ring 92 is movably connected to the bottom of the pressing plate 4. There are four connecting rings 92 which are distributed at equal intervals in a ring shape. A connecting rod 93 is fixedly connected to the inner wall of the connecting ring 92. The surface of the connecting rod 93 is movably connected to the inner wall of the supporting spring 8. The other end of the connecting rod 93 penetrates through the fixed cylinder 91 and extends to the bottom of the fixed cylinder 91.

One end of the supporting spring 8 close to the pressing plate 4 is fixedly connected to the bottom of the connecting ring 92, and the other end of the supporting spring 8 is fixedly connected to the bottom of the inner wall of the fixed cylinder 91.

[0026] As a technical optimization scheme of the present utility model, by providing the connecting mechanism 9, the fixed cylinder 91 can play a guiding role for the connecting rod 93, and the connecting rod 93 can play a guiding role for the supporting spring 8, so as to avoid the deviation of the supporting spring 8 during expansion and contraction. At the same time, the supporting spring 8 and the connecting rod 93 can stably support the filter plate 6.

[0027] Reference Figure 2 , the limiting component 10 includes a through hole 101. The diameter of the connecting ring 92 is the same as that of the through hole 101. A limiting ring 102 is fixedly connected to the bottom of the surface of the connecting rod 93. The top of the limiting ring 102 is in contact with the bottom of the fixed cylinder 91.

[0028] As a technical optimization scheme of the present utility model, by providing the limiting component 10, when the filter plate 6 moves downward, it can drive the connecting rod 93 and the connecting ring 92 to move downward. When the bottom of the filter plate 6 is in contact with the top of the fixed ring 7, the connecting ring 92 can enter the inside of the through hole 101, so as to avoid the existence of a gap between the fixed ring 7 and the filter plate 6 resulting in insufficient raw material pressing. The limiting ring 102 can prevent the connecting rod 93 from separating from the fixed cylinder 91.

[0029] Reference Figure 2 , one end of the connecting rod 93 away from the fixed cylinder 91 is fixedly connected to a single-head screw 11. The other end of the single-head screw 11 penetrates through the filter plate 6 and is threadedly connected to a button cap 12. The single-head screw 11 is movably connected to the filter plate 6.

[0030] As a technical optimization scheme of the present utility model, by providing the single-head screw 11 and the button cap 12, the button cap 12 can fix and limit the single-head screw 11 and the connecting rod 93. By rotating the button cap 12 to separate it from the single-head screw 11, it is convenient for the user to disassemble the filter plate 6.

[0031] Reference Figure 3 , four relief holes 13 are opened at the bottom of the pressing plate 4. The four relief holes 13 are distributed at equal intervals in a ring shape. Four convex cylinders 14 are fixedly connected to the top of the pressing plate 4. The convex cylinders 14 communicate with the relief holes 13. The inner diameters of the relief holes 13 and the convex cylinders 14 are the same as the diameter of the button cap 12.

[0032] As a technical optimization solution of the present utility model, by providing an avoidance hole 13 and a convex cylinder 14, when the pressing plate 4 moves downward to contact the top of the pressing plate 4, the button cap 12 can enter the interior of the convex cylinder 14 through the avoidance hole 13, so as to avoid the existence of a gap between the pressing plate 4 and the filter plate 6.

[0033] Reference Figure 1 , a movable ring 15 is movably connected to the surface of the support frame 2, and a shovel plate 16 is fixedly connected to the rear side of the surface of the movable ring 15.

[0034] As a technical optimization solution of the present utility model, by providing the movable ring 15 and the shovel plate 16, after the pressing is completed, a small amount of pressed oil waste usually adheres to the bottom of the pressing plate 4. At this time, by rotating the movable ring 15, the shovel plate 16 can be driven to rotate to scrape and clean the bottom of the pressing plate 4.

[0035] Reference Figure 1 and Figure 2 , positioning rings 17 are movably connected to both the top and bottom of the movable ring 15, the inner wall of the positioning ring 17 is fixedly connected to the surface of the support frame 2, and a secondary filter hopper 18 is fixedly connected to the bottom of the filter plate 6. The diameter of the secondary filter hopper 18 is the same as the inner diameter of the fixed ring 7.

[0036] As a technical optimization solution of the present utility model, by providing the positioning ring 17 and the secondary filter hopper 18, the positioning ring 17 can limit the up and down movement of the movable ring 15, so that the shovel plate 16 can always be located at the bottom of the pressing plate 4. The secondary filter hopper 18 can perform secondary filtration on the edible oil falling through the filter plate 6. When the user disassembles the filter plate 6, the secondary filter hopper 18 can be driven to move synchronously, so as to facilitate the user to clean it.

[0037] Working principle and usage process of the present utility model: During use, when oil pressing of edible oil is required, first place the raw materials for oil pressing on the top of the filter plate 6. Then, by starting the hydraulic rod 3, the piston end of the hydraulic rod 3 can drive the pressing plate 4 to move downward. When the pressing plate 4 contacts the oil pressing raw materials and continues to move downward, it can drive the filter plate 6 to move downward. At this time, the support spring 8 is gradually pressed and contracted inside the fixed cylinder 91. When the bottom of the filter plate 6 fits against the top of the fixed ring 7, the filter plate 6 stops moving. At this time, the pressing plate 4 presses the oil pressing raw materials, and the edible oil produced by pressing can flow out from the bottom of the pressing cylinder 1 through the filtration of the filter plate 6 and the secondary filter hopper 18 in sequence. After the pressing is completed, the hydraulic rod 3 drives the pressing plate 4 to move upward back to its original position. The user can scrape and clean the waste residues remaining at the bottom of the pressing plate 4 by rotating the scraping plate 16. At the same time, when the pressing plate 4 moves away from the filter plate 6, the support spring 8 rebounds and restores, and can gradually push the filter plate 6 to move upward. At this time, the user can collect and clean the oil pressing waste on the top of the filter plate 6. When it is necessary to clean the filter plate 6 and the secondary filter hopper 18, first rotate the knob cap 12 to separate it from the single-headed screw 11, and then pull out the filter plate 6 and the secondary filter hopper 18 from the inside of the pressing cylinder 1. The disassembly is relatively convenient.

[0038] To sum up: For this pressing device for edible oil production, by setting the fixed ring 7 and the support spring 8, the support spring 8 can support the filter plate 6 on the upper layer of the inner wall of the pressing cylinder 1, thus facilitating the user to clean the filter plate 6. When the pressing plate 4 moves downward, it can drive the filter plate 6 to move downward. When the bottom of the pressing plate 4 fits against the top of the fixed ring 7, it can position the pressing plate 4. When the pressing plate 4 moves upward, the support spring 8 can push the filter plate 6 back to its original position, solving the problem that since the pressing plate has a strong squeezing force on the raw materials during pressing, the raw materials will also be in close contact with the filter plate, resulting in some raw materials entering the through holes inside the filter plate and causing blockage of the filter plate. And the filter plate is fixedly installed in the middle area of the inner wall of the pressing cylinder, so it is not convenient for the user to clean it. Also, setting a box door on the pressing cylinder will cause a gap between the box door and the pressing cylinder, resulting in the outflow of edible oil, so the practicality is not high.
