Description

Technical Field

[0001] This utility model relates to the field of screw presses, and in particular to a low-temperature cold-pressing oil screw press with adjustable gap. Background Technology

[0002] The low-temperature cold-pressing screw press is a new generation of screw oil pressing equipment specifically designed for cold pressing various oilseeds. It employs the screw pressing principle, pressing at low temperatures (typically controlled below 60℃), avoiding the damage to oil quality caused by high temperatures and preserving the nutritional components of the oilseeds to the greatest extent. This equipment is particularly suitable for pressing organic plants and high-value-added cash crops, offering advantages such as high oil yield, low residual oil in the oil cake, and good oil quality. During the pressing process, it does not come into contact with any chemical additives, ensuring the purity and nutritional value of the processed oil and oil cake. Furthermore, the low-temperature cold-pressing screw press is also suitable for a variety of vegetable oils, offering high flexibility and practicality.

[0003] In traditional low-temperature cold-pressing screw presses, the screen cylinder apertures are fixed and cannot be adjusted, a design with significant drawbacks. Because material properties, pressure, and temperature can vary during pressing, a fixed aperture cannot meet the demands of different operating conditions. This can lead to reduced pressing efficiency, affecting oil yield and oil quality. Furthermore, a fixed aperture can cause material blockage, increasing equipment maintenance difficulty and downtime. Therefore, this design limits the press's flexibility and adaptability, hindering improvements in production efficiency and product quality. Thus, a low-temperature cold-pressing screw press with adjustable apertures is needed to address these issues. Summary of the Invention

[0004] The main objective of this invention is to provide a low-temperature cold-pressing screw press with adjustable gap, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A low-temperature cold-pressing screw press with adjustable gap includes a main pipe. A screen cylinder structure is fixedly inserted into the main pipe. The screen cylinder structure consists of a screen cylinder body, a first connecting sleeve, and a second connecting sleeve. The first and second connecting sleeves are respectively fixedly installed at both ends of the screen cylinder body. Several adjusting components are installed on the screen cylinder structure. Each adjusting component consists of an arc-shaped connecting plate, an adjusting tube, a connecting block, and an insert block. Several adjusting tubes are fixedly inserted into the arc-shaped connecting plate. The connecting block is fixedly installed on the outer wall of the arc-shaped connecting plate. The insert block is fixedly installed at one end of the connecting block. A limiting component is fitted onto the screen cylinder structure and the several adjusting components. The limiting component consists of a fixed ring, a movable limiting ring, and a limiting spring. The limiting spring is fixedly installed between the fixed ring and the movable limiting ring.

[0007] Preferably, a feed hopper and a drive device are fixedly installed on the main pipeline.

[0008] Preferably, the screen cylinder body of the screen cylinder structure has several oil discharge holes, and the second connecting sleeve has several fitting grooves arranged in a ring.

[0009] Preferably, the arc-shaped connecting plate on the adjusting component is tightly attached to the outer wall of the screen cylinder body, and the insert block is embedded in the insert groove opened on the second connecting sleeve.

[0010] Preferably, the arc-shaped connecting plate on the adjusting component has a plurality of mounting holes evenly provided, the adjusting tube is fixedly inserted into the mounting holes, and the adjusting tube is also inserted into the oil outlet hole.

[0011] Preferably, the fixing ring on the limiting component is fixedly sleeved on the second connecting sleeve, the movable limiting ring is movably sleeved on the second connecting sleeve, and the movable limiting ring is simultaneously movably sleeved on several inserts on several adjusting components.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By setting up a screen cylinder structure consisting of a screen cylinder body, a first connecting sleeve, and a second connecting sleeve, and by setting a detachable adjusting component on the screen cylinder structure, the gap of the oil outlet holes on the screen cylinder body can be adjusted, that is, the diameter of the oil outlet holes can be adjusted. This design allows the press to flexibly adjust the diameter of the oil outlet holes according to different material characteristics and pressing requirements, thereby optimizing the pressing effect. By increasing or decreasing the diameter of the oil outlet holes, the material throughput speed and pressing pressure during the pressing process can be controlled, thereby improving the oil yield and oil quality. In addition, the adjustable diameter of the oil outlet holes can effectively prevent material blockage, reduce equipment failure and maintenance costs. This design enhances the adaptability and flexibility of the press, helps to improve production efficiency and product quality, and brings greater convenience and benefits to the production of low-temperature cold-pressed oil. By setting a limiting component, it is easy to disassemble and assemble the adjusting component, thus making the adjustment efficiency of the oil outlet hole diameter high.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a low-temperature cold-pressing screw press with adjustable gap includes a main pipe 1. A screen cylinder structure 2 is fixedly inserted into the main pipe 1. The screen cylinder structure 2 consists of a screen cylinder body 7, a first connecting sleeve 8, and a second connecting sleeve 9. The first connecting sleeve 8 and the second connecting sleeve 9 are respectively fixedly installed at both ends of the screen cylinder body 7. Several adjusting components 3 are installed on the screen cylinder structure 2. The adjusting components 3 consist of an arc-shaped connecting plate 12, adjusting pipes 14, connecting blocks 15, and inserting blocks 16. There are several adjusting pipes 14, all of which are fixedly inserted into the arc-shaped connecting plate 12. The connecting blocks 15 are fixedly installed on the outer wall of the arc-shaped connecting plate 12, and the inserting blocks 16 are fixedly installed at one end of the connecting blocks 15. The screen cylinder structure 2 and several adjusting components 3 are also shown. A limiting component 4 is fitted onto the adjusting component 3. The limiting component 4 consists of a fixed ring 17, a movable limiting ring 18, and a limiting spring 19. The limiting spring 19 is fixedly installed between the fixed ring 17 and the movable limiting ring 18. A feeding hopper 5 and a driving device 6 are fixedly installed on the main pipe 1. Several oil discharge holes 10 are opened on the screen body 7 of the screen cylinder structure 2. Several embedding grooves 11 are opened in a ring on the second connecting sleeve 9. When pressing oil, the driving device 6 can be started. At this time, the driving device 6 will drive the screw in the main pipe 1 and the screen cylinder structure 2 to rotate. Then the raw material is put into the feeding hopper 5. Then the raw material will enter the main pipe 1 and the screen cylinder structure 2 and be squeezed by the screw. Then the oil in the raw material will flow out through the oil outlet hole 10.

[0022] Therefore, by setting up a screen cylinder structure 2 consisting of a screen cylinder body 7, a first connecting sleeve 8, and a second connecting sleeve 9, and by setting a detachable adjustment component 3 on the screen cylinder structure 2, the gap of the oil outlet hole 10 on the screen cylinder body 7 can be adjusted, that is, the diameter of the oil outlet hole 10 can be adjusted. This design allows the press to flexibly adjust the diameter of the oil outlet hole 10 according to different material characteristics and pressing requirements, thereby optimizing the pressing effect. By increasing or decreasing the diameter of the oil outlet hole 10, the material throughput speed and pressing pressure during the pressing process can be controlled, thereby improving the oil yield and oil quality. In addition, the adjustable diameter oil outlet hole 10 can effectively prevent material blockage, reduce equipment failure and maintenance costs. This design enhances the adaptability and flexibility of the press, helps to improve production efficiency and product quality, and brings greater convenience and benefits to the production of low-temperature cold-pressed oil. By setting up the limiting component 4, it is convenient to disassemble and assemble the adjustment component 3, thereby making the adjustment efficiency of the diameter of the oil outlet hole 10 higher.

[0023] Specifically, the arc-shaped connecting plate 12 on the adjusting component 3 is tightly attached to the outer wall of the screen cylinder body 7. The insert block 16 is embedded in the insert groove 11 opened on the second connecting sleeve 9. Several mounting holes 13 are evenly opened on the arc-shaped connecting plate 12 on the adjusting component 3. The adjusting tube 14 is fixedly inserted into the mounting hole 13 and simultaneously inserted into the oil outlet hole 10. The fixing ring 17 on the limiting component 4 is fixedly sleeved on the second connecting sleeve 9, and the moving limiting ring 18 is movably sleeved on the second connecting sleeve 9. The moving limiting ring 18 is simultaneously movably sleeved on several insert blocks 16 on several adjusting components 3. When it is necessary to adjust the oil outlet hole 10, the adjusting component 3 can be adjusted. The adjusting tube 14 is inserted into the oil outlet hole 10, or the adjusting tube 14 is pulled out of the oil outlet hole 10. Before this, the moving limiting ring 18 needs to be pushed towards the fixed ring 17, so that the moving limiting ring 18 moves away from the outside of the mounting groove 11. During this process, the limiting spring 19 is compressed by the moving limiting ring 18 and the fixed ring 17. After the installation or removal of the adjusting component 3 is completed, the moving limiting ring 18 is released. At this time, under the elastic force of the limiting spring 19, the moving limiting ring 18 will move back to its original position. When the adjusting tube 14 is inserted into the oil outlet hole 10, the hole through which oil can pass will become smaller. Conversely, when the adjusting tube 14 is pulled out of the oil outlet hole 10, the hole through which oil can pass will become larger.
