Description

Technical Field

[0001] This utility model relates to the field of cold pressing of tea seed oil, specifically a cold pressing processing device for tea seed oil. Background Technology

[0002] Oil presses are core equipment for extracting oil from oil crops through physical pressing methods such as screw, hydraulic, and twin-screw presses, chemical solvent extraction, or electric heating assistance. They come in various technical types and have a wide range of applications. Physical presses dominate the market due to their natural and additive-free characteristics and are suitable for home use, small and medium-sized oil mills, and industrial refining. Chemical solvent equipment has a high oil yield but poses a risk of residue and is mainly used for high-oil-content raw materials such as soybeans. Electric heating equipment is used as an auxiliary to accelerate oil extraction.

[0003] In existing hydraulic oil presses, the pressing barrel containing the pressed materials, such as tea seeds, is prone to shaking during operation and cannot be properly secured. This results in incomplete pressing of the materials, affecting work efficiency. Furthermore, the disposal of waste residue after pressing is inconvenient, further reducing work efficiency. Therefore, the inventor urgently needs to design a device that can secure the pressing barrel, improve oil pressing efficiency, and facilitate the disposal of waste residue by workers. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a cold pressing device for tea seed oil to solve the technical problems of shaking during the pressing process and inconvenience in handling residues in traditional cold pressing devices for tea seed oil.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cold pressing device for tea seed oil, comprising an oil press body, two connecting blocks arranged below the oil press body, electric push rods movably arranged at both connecting blocks, hooks arranged below the electric push rods, an oil pressing barrel with several round holes arranged in the middle of the oil press body, the bottom of the oil pressing barrel having an open structure, and a circular base provided on the oil press body.

[0006] By adopting the above technical solution, the initial positioning stability of the pressing barrel is achieved by setting the main body of the oil press with a circular base and cooperating with the open bottom of the pressing barrel.

[0007] Furthermore, the retraction of the electric push rod causes the hook to move upward, thereby pulling up the oil pressing barrel.

[0008] By adopting the above technical solution, the action logic of the electric push rod retracting to drive the hook to move upward transforms the traditional passive load-bearing into active lifting and locking, which first strengthens the impact resistance of the oil pressing barrel under high pressure working conditions and eliminates barrel vibration when the hydraulic rod applies pressure.

[0009] Furthermore, the bottom end of the oil pressing barrel is fitted into the circular base, and the circular base fixes the position of the oil pressing barrel.

[0010] By adopting the above technical solution, the sleeve structure between the bottom of the oil pressing barrel and the circular base forms a physical self-locking effect, which first ensures that the central axis of the barrel is always precisely aligned with the pressing direction of the hydraulic rod, thus avoiding the failure of the seal or the blockage of the round hole due to uneven load.

[0011] Furthermore, an oil collection tray is provided below the oil pressing barrel, and an oil outlet pipe is provided below the oil collection tray. The oil collection tray is fixedly connected to the circular base.

[0012] By adopting the above technical solution, the oil collection tray fixed to the circular base constructs a closed flow channel. First, the oil seeping through the holes of the oil pressing barrel is completely intercepted and collected, preventing splashing pollution and ensuring the hygiene level of the oil.

[0013] Furthermore, the outer ring of the oil pressing barrel is provided with a plurality of first blocks, and the inside of the oil collecting tray is provided with a plurality of second blocks, the first blocks being interlocked with the second blocks.

[0014] By adopting the above technical solution, the three-dimensional interlocking network formed by the first baffle on the outer ring of the oil pressing barrel and the second baffle inside the oil receiving tray first constructs multiple anti-overflow barriers, preventing oil from escaping from the barrel-tray joint during the initial oil spraying stage of pressing.

[0015] Furthermore, a rotating base is provided below the oil collection tray, and the oil collection tray is rotatably connected to the main body of the oil press through the rotating base.

[0016] By adopting the above technical solution, the rotating base supports the rotational connection between the oil collection tray and the main body of the oil press, which allows the operator to adjust the tilt angle of the oil collection tray according to cleaning needs, thereby achieving the collection and discharge of residual oil and the centralized cleaning of sediment.

[0017] Furthermore, a hydraulic device is provided above the main body of the oil press, and a hydraulic rod is provided on the main body of the oil press. The hydraulic device controls the hydraulic rod.

[0018] By adopting the above technical solution, the hydraulic device can precisely control the hydraulic rod, firstly adapting to the low-impact and slow-pressurization characteristics required for the cold pressing process of tea seeds, and then gradually applying pressure to avoid instantaneous temperature rise of the material that could damage the active components of the oil.

[0019] Furthermore, a control panel is provided at the front of the main body of the oil press, and the hydraulic device and the electric push rod are electrically connected to the control panel.

[0020] By adopting the above technical solution, the control board integrates the timing logic of the hydraulic device and the electric actuator, realizing full-process automated control and significantly reducing the intensity of manual operation and the skill threshold.

[0021] In summary, the present invention has the following main advantages:

[0022] This invention achieves initial positioning by attaching a circular base to the bottom of the oil pressing barrel. Simultaneously, the retraction of the electric push rod pulls the oil pressing barrel upwards with a hook, forming a two-way mechanical constraint. This completely suppresses barrel swaying during the pressing process, ensuring that the pressure of the hydraulic rod is fully applied to the oilseeds, thereby improving oil yield and pressing efficiency. Furthermore, the open-type oil pressing barrel and the electric push rod linkage structure enables efficient cleaning of waste residue. After pressing, the electric push rod extends to release the constraint, allowing operators to directly remove the oil pressing barrel full of waste residue, eliminating the cumbersome process of traditional waste removal and significantly reducing equipment downtime.

[0023] This invention ensures reliable oil collection by fixing the oil collection tray to the circular base. The oil leaking from the oil pressing barrel flows into the oil collection tray through the guide channel formed by the first and second blocks, and is then discharged in a directional manner through the oil outlet pipe, thus preventing oil splashing and pollution and maintaining the purity of the oil.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] A cold pressing device for tea seed oil, such as Figure 1-4As shown, the oil press includes a main body 1. Two connecting blocks 4 are located below the main body 1, and electric push rods 5 are movably mounted on both connecting blocks 4. Hooks 6 are located below each electric push rod 5. An oil pressing barrel 7 with several round holes is located in the middle of the main body 1. The bottom of the oil pressing barrel 7 has an open structure. The main body 1 has a circular base 9. The cooperation between the main body 1 with the circular base 9 and the open-bottomed oil pressing barrel 7 achieves initial positioning stability of the barrel. Simultaneously, the electric push rods 5 suspended by the connecting blocks 4 on both sides and the bottom hooks 6 form a dynamic locking mechanism, applying bidirectional constraints to the oil pressing barrel 7 during the pressing process: the bottom sleeve inhibits horizontal displacement, and the top hook eliminates vertical swaying, thereby significantly improving the pressing pressure transmission efficiency and avoiding oil residue problems caused by barrel misalignment. Furthermore, the open-bottom design provides a basic structural support for subsequent automated waste cleaning.

[0031] See Figure 1 , Figure 2 , Figure 3 The retraction of the electric push rod 5 causes the hook 6 to move upward, thereby lifting the oil pressing barrel 7. The action logic of the electric push rod 5 retracting and causing the hook 6 to move upward transforms the traditional passive load-bearing into active lifting and locking. First, it enhances the impact resistance of the oil pressing barrel 7 under high pressure working conditions and eliminates barrel vibration when the hydraulic rod 3 applies pressure. At the same time, after the pressing is completed, the constraint can be instantly released by simply extending the electric push rod 5 in the opposite direction. This greatly simplifies the manual disassembly steps and avoids the risk of hammering the barrel to remove it, providing a seamless technical guarantee for quickly entering the waste residue treatment stage.

[0032] See Figure 1 , Figure 2 , Figure 3 The bottom of the oil pressing barrel 7 is fitted with the circular base 9, which fixes the position of the oil pressing barrel 7. The fitting structure between the bottom of the oil pressing barrel 7 and the circular base 9 forms a physical self-locking effect, firstly ensuring that the central axis of the barrel is always precisely aligned with the pressing direction of the hydraulic rod 3, avoiding the failure of the seal or the blockage of the round hole due to uneven load. At the same time, this nested design compensates for the processing and assembly tolerances by mechanical limiting. Even if the equipment undergoes slight deformation after long-term use, it can still maintain the basic positioning accuracy of the barrel, significantly reducing the frequency of equipment maintenance and extending the life of key components, fundamentally eliminating the risk of stress concentration or stripping caused by traditional threaded fastening.

[0033] See Figure 1 , Figure 2 , Figure 3An oil collection tray 8 is installed below the oil pressing barrel 1, and an oil outlet pipe 13 is installed below the oil collection tray 8. The oil collection tray 8 is fixedly connected to the circular base 9. The oil collection tray 8, fixed to the circular base 9, forms a closed flow channel. First, the oil seeping through the holes of the oil pressing barrel 7 is completely intercepted and collected, preventing splashing and pollution and ensuring the hygiene level of the oil. At the same time, the oil outlet pipe 13 at the bottom of the oil collection tray 8 realizes continuous directional oil discharge, avoiding the oil from remaining and oxidizing inside the equipment. It is especially suitable for delicate oils such as tea seed oil that require low-temperature preservation. The rigid connection design between the oil collection tray and the base ensures that the collection system does not leak under the pressing vibration condition, significantly improving the oil recovery rate.

[0034] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The outer ring of the oil pressing barrel is provided with several first baffles 101, and the inside of the oil collecting tray 8 is provided with several second baffles 102. The first baffles 101 and the second baffles 102 are interlocked. The three-dimensional interlocking network formed by the first baffles 101 on the outer ring of the oil pressing barrel 7 and the second baffles 102 inside the oil collecting tray 8 firstly constructs multiple anti-overflow barriers, preventing oil from overflowing from the barrel-tray joint during the initial oil spraying stage of pressing. At the same time, the baffle interlocking mechanism forces the oil pressing barrel 7 and the oil collecting tray 8 to maintain a preset gap, which not only avoids direct contact and friction damage to the barrel wall, but also forms a uniform annular oil collecting groove to optimize the flow efficiency. In particular, it can alleviate the problem of wall-hanging loss caused by surface tension when dealing with high-viscosity tea seed oil.

[0035] See Figure 1 , Figure 2 , Figure 3 A rotating base 11 is provided below the oil collection tray 8. The oil collection tray 8 is rotatably connected to the main body 1 of the oil press through the rotating base 11. The rotating base 11 supports the rotational connection between the oil collection tray 8 and the main body 1 of the oil press. First, it allows the operator to adjust the tilt angle of the oil collection tray according to the cleaning needs, so as to realize the collection and discharge of residual oil and the centralized cleaning of sediment. At the same time, this rotatable structure can be moved laterally out of the operating area when changing the oil pressing barrel 7, avoiding the spatial interference problem caused by the traditional fixed oil collection tray and significantly reducing the maintenance difficulty. Its rotational damping characteristics also ensure that the collection system does not deflect unexpectedly during the operation of the equipment, and keep the oil outlet pipe 13 always in the preset position.

[0036] See Figure 1 , Figure 2 , Figure 3A hydraulic device 2 is installed above the main body 1 of the oil press, and a hydraulic rod 3 is installed on the main body 1. The hydraulic device 2 controls the hydraulic rod 3. The precise control of the hydraulic device 2 on the hydraulic rod 3 first adapts to the low impact and slow pressure increase characteristics required for the cold pressing process of tea seeds. By gradually applying pressure, it avoids the instantaneous temperature rise of the material from damaging the active components of the oil. At the same time, the power system works in coordination with the barrel fixing mechanism: the hydraulic device is only allowed to start after the electric push rod 5 has completed the barrel locking, forming a mechanical-hydraulic interlock protection. This not only prevents structural overload caused by misoperation, but also ensures that the pressure is fully applied to the constrained material, thereby improving the integrity of the oil extracted in a single pressing from the source.

[0037] See Figure 1 , Figure 2 , Figure 3 A control board 12 is installed in front of the main body 1 of the oil press. The hydraulic device 2 and the electric push rod 5 are electrically connected to the control board 12. The control board 12 integrates the timing logic of the hydraulic device 2 and the electric push rod 5 to realize full-process automated control, which greatly reduces the intensity of manual operation and the skill threshold. At the same time, the logic interlock function of the control system completely eliminates the risk of misoperation: for example, the electric push rod 5 is prohibited from releasing the hook 6 when the hydraulic rod 3 is not fully reset, so as to avoid safety accidents caused by sudden load release. While improving production efficiency, an inherently safe equipment architecture is constructed.

[0038] The implementation principle of this embodiment is as follows: During operation, the bottom end of the oil pressing barrel 7 is first fitted onto the circular base 9 of the oil press body 1 for initial positioning. The electric push rod 5 is activated and retracted through the connecting block 4, driving the hook 6 below to lift the oil pressing barrel 7 upward, forming a vertical mechanical constraint. At this time, the hydraulic device 2 controls the hydraulic rod 3 to press down, cold pressing the tea seeds in the barrel. The oil flows out from the round hole of the oil pressing barrel 7 to the oil collection tray 8 and is collected through the oil outlet pipe 13.

[0039] After pressing, the hydraulic rod 3 resets, and the electric push rod 5 extends in the opposite direction, causing the hook 6 to disengage from the oil pressing barrel 7. The oil pressing barrel 7, which is full of waste residue, is then manually removed for cleaning. During this process, the oil receiving tray 8 remains fixed to the circular base 9. The interlocking structure between the second stop 102 inside the oil receiving tray 8 and the first stop 101 on the outer ring of the oil pressing barrel 7 ensures that the oil flows into the oil receiving tray 8 in a directional manner. At the same time, the base 11 rotates to support the angle adjustment of the oil receiving tray 8 to assist in cleaning. The entire process is coordinated by the control panel 12, which controls the operation of the hydraulic device 2 and the electric push rod 5.
