Description

Technical Field

[0001] This utility model relates to a horizontal four-column oil press, and in particular to a mechanism for pressing materials. Background Technology

[0002] The main structure of the horizontal four-column oil press is as disclosed in the Chinese utility model patent document CN 204414631 U, entitled "A Novel Horizontal Hydraulic Oil Press". The roasted or steamed material is wrapped in filter cloth and placed in the oil ring 4, which is positioned between four support rods 11. Pressure is applied by the oil pressing plate 3 through external mechanical forces such as hydraulic pressure, levers, lead screws, or gravity, pressing the roasted or steamed material inside the oil ring 4. This forces the oil to be squeezed out from the gaps between the oil rings 4.

[0003] In existing technology, the oilseeds are partially exposed and partially enclosed in a circular oil ring. When pressure is applied, the oilseeds easily overflow from the gaps between the oil rings without being fully pressed, resulting in a waste of raw materials and leakage. At the same time, the flow of the pressed oil is restricted, and when the overflow of the leakage residue dries, it can block the flow channels of the oil, causing the pressed oil to remain in the oil ring and not flow out, resulting in a large amount of waste. Utility Model Content

[0004] To address the aforementioned drawbacks, the technical problem this utility model aims to solve is to provide a material-encapsulating pressing mechanism for a horizontal four-column oil press, avoiding residue leakage and effectively reducing oil residue waste. The technical solution adopted by this utility model is a material-encapsulating pressing mechanism for a horizontal four-column oil press, comprising several pressing units arranged parallel between four support rods. The pressing unit is characterized by comprising elastic collars and flow-guiding isolation plates, with two flow-guiding isolation plates sandwiched between adjacent elastic collars. Each flow-guiding isolation plate has several evenly distributed flow-guiding grooves, with the two ends of each groove located on opposite sides of the plate. Several oil leakage holes are evenly distributed within each groove. The openings of each flow-guiding groove on the two isolation plates are arranged opposite each other. The elastic collar consists of two axially elastically connected rings, one ring having a connecting sleeve fixed inside, and the other ring nested outside the connecting sleeve. The cavity formed by the elastic collars and the flow-guiding isolation plates constitutes a material-containing cavity.

[0005] In one embodiment, the flow guide groove is a V-shaped groove with a V-shaped cross-section, and the oil leakage hole is located at the bottom of the V-shaped groove.

[0006] In one embodiment, the oil leakage hole is a tapered hole, with the end closer to the opening of the guide groove being smaller.

[0007] In one embodiment, several lugs are evenly distributed around the outer periphery of the two collars, and a spring is installed between two corresponding lugs, with the two ends of the spring acting on the corresponding lugs of the two collars respectively.

[0008] In one embodiment, the spring is fitted onto a pin, the top of which is provided with a limiting cap; the pin passes through a mounting hole of a collar, and the bottom end of the pin is fixed to a lug of another collar.

[0009] The beneficial effects of this utility model are as follows: Compared with the prior art, the material-enclosed pressing mechanism provided by this utility model has its receiving cavity for placing the oil-pressing material fully enclosed by an elastic collar and a flow-guiding isolation plate, effectively preventing residue leakage. The oil pressed out of the receiving cavity is squeezed and flows out from the oil leakage holes on the flow-guiding isolation plate to the space between the two flow-guiding isolation plates. The openings of the various flow-guiding grooves on the two plates arch together to form a cavity channel. Both ends of the elastic collar can leak oil straight out and flow out laterally, facilitating the oil to flow out of the elastic collar and effectively reducing the waste of residual pressed oil. It also has the advantage of convenient loading and unloading.

[0025] See appendix Figure 1-8 This describes a specific structure of the present invention. The material-enclosed pressing mechanism of the horizontal four-column oil press consists of several pressing units arranged side by side between four support rods 6. Each pressing unit is composed of an elastic collar 1 and a flow guide isolation plate 2, with two flow guide isolation plates 2 sandwiched between two adjacent elastic collars 1.

[0026] Each flow guide plate 2 has several flow guide grooves 201 evenly distributed on it. Because the elastic collar 1 and the flow guide plate 2 are circular bodies of corresponding size, and the two ends of each flow guide groove 201 are located on opposite sides of the flow guide plate, the extracted oil can flow out from both ends of each flow guide groove 201.

[0027] Each guide groove 201 contains a plurality of evenly distributed oil leakage holes 202. In this example, the guide groove 201 is a V-shaped groove with a V-shaped cross-section, and the oil leakage holes 202 are located at the bottom of the V-shaped groove. The oil leakage holes 202 are conical holes, with one end of the conical hole closer to the opening of the guide groove 201 being smaller and the other end being larger. The extracted oil enters the oil leakage hole from the larger end and flows into the guide groove 201 from the smaller end (i.e., straight oil leakage).

[0028] The openings of each flow-guiding groove 201 of the two flow-guiding isolation plates 2 sandwiched between two adjacent elastic rings 1 are arranged opposite each other, arching together to form a cavity channel. This allows oil flowing into the flow-guiding groove 201 to flow out of the elastic ring 1 along the cavity channel and be collected by the container below (i.e., flow out laterally).

[0029] The elastic collar consists of a first collar 3 and a second collar 4 that are axially elastically connected. The inner side of the first collar 3 is fixedly connected to the connecting sleeve 301, and the second collar 4 is nested on the outer wall of the connecting sleeve 301. In other embodiments, the inner side of the second collar 4 can also be fixedly connected to the connecting sleeve 301, and the first collar 3 can be nested on the outer wall of the connecting sleeve 301. The cavity formed by each elastic collar 1 and the flow-guiding isolation plates 2 at both ends is a receiving cavity for filling materials.

[0030] In the example, four lugs 5 are evenly distributed on the outer periphery of the first collar 3 and the second collar 4. A spring 501 is installed between the lugs 5 corresponding to the two collars. The two ends of the spring 501 act on the lugs 5 corresponding to the two collars, thereby forming the axial elastic connection. In the example, the spring 501 is fitted onto the pin 502, and the top of the pin 502 is provided with a limiting cap 504. After the pin 502 passes through the mounting hole 503 of one lug 5, its bottom end is threadedly fixed in the threaded hole 504 of the corresponding other lug 5. The limiting cap 504 cannot pass through the mounting hole 503.

[0031] The above-mentioned material fully enclosed pressing mechanism is adopted, such as Figure 1 As shown, the pressure plate 7 applies pressure in the direction of the arrow, each elastic ring 1 is compressed, the spring 501 contracts, and the first ring 3 and the second ring 4 slide together along the connecting sleeve 301, reducing the space of the material-filled cavity and pressing the material. During this process, because the cavity is completely enclosed by the elastic rings 1 (composed of the first ring 3, the second ring 4, and the connecting sleeve 301) and the guide plate 2, leakage is effectively prevented. The oil extracted from the cavity flows straight out from the oil leakage holes 202 on the guide plate 2 into the guide groove 201 between the two guide plates 2, and then flows laterally out along the cavity formed by the arching of the two guide grooves 201. The guide plates 2 at both ends of each elastic ring 1 allow oil to flow straight out and laterally out of the elastic ring, where it is collected by the container below (not shown in the figure). Smooth oil flow effectively reduces residual waste of the extracted oil. Moreover, compared to existing material packaging, this invention only requires filling the refrigerated or steamed material into the accommodating cavity, making loading and unloading more convenient.

[0032] The embodiments of the present invention disclosed above are merely illustrative of the present invention. The embodiments do not exhaustively describe all details, nor do they limit the present invention to the specific implementations described. Obviously, many modifications and variations can be made based on the content of this specification. This specification selects and describes these embodiments in detail with reference to the accompanying drawings to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present invention. Therefore, the present invention is limited only to the claims and their full scope and equivalents, and not to the specific embodiments disclosed.
