Description

Technical Field

[0001] The present invention relates to the field of tea seed oil extraction, and particularly to a tea seed oil extraction device for tea oil production. Background Art

[0002] Tea seed oil, also known as camellia oil and camellia seed oil, is a natural vegetable oil extracted from the seeds of the camellia oleifera tree, and is known as the "Oriental olive oil". Clinical trials have shown that ingesting 25 g of tea seed oil per day can reduce low-density lipoprotein cholesterol by 12%-16%, significantly reducing the risk of atherosclerosis.

[0003] The tea seed oil extraction process is a process of extracting oil from camellia seeds by physical or chemical methods, mainly including three stages: pretreatment, pressing, and refining. Among them, pressing is the core link for oil extraction. The current mainstream pressing method is the screw pressing method, and its working principle is to squeeze the oil material by the rotation of the screw shaft, generating high pressure to release the oil from the cells. Using a screw oil press for continuous pressing, the pressure can reach 70-100 MPa, and the oil extraction efficiency is high.

[0004] However, the current oil extraction device is relatively difficult to disassemble and clean, and at the same time, the operation of placing and removing the tea cake is not convenient. When placing the tea cake, the tea cake needs to be supported by a bottom tray, and the tea cakes are stacked in rows. When the oil extraction is completed, the tea cakes are pressed together under pressure and are difficult to separate and remove. Generally, tools are needed to pry them off one by one, which restricts the overall pressing efficiency. Summary of the Invention

[0005] According to the problems raised in the background art, the present invention provides a tea seed oil extraction device for tea oil production to solve, and the following is a further elaboration of the present invention.

[0006] A tea seed oil extraction device for tea oil production includes a machine base, a first motor is connected to one side of the machine base, a screw rod is rotatably provided on the machine base, the screw rod is connected to the output shaft of the first motor, a slide rail beam is connected to the machine frame, and a plurality of bearing seats are slidably arranged on the slide rail beam. The bearing seats carry a pressing cake assembly and a cake carrying assembly arranged at intervals. A screw sleeve is connected to one side of the bearing seat farthest from the first motor, the screw sleeve is fitted on the screw rod, and the pressing cake assemblies are arranged on the bearing seats farthest and closest to the first motor, and the cake carrying assembly is arranged between the pressing cake assemblies. The oil cake is arranged on the cake carrying assembly.

[0007] Preferably, the bearing seat is a concave frame with an open mouth, and a chute is provided at the bottom; a hook is rotatably connected to the bottom of the bearing seat, and a torsion spring is connected between the rotating end of the hook and the bearing seat. The free end of the hook is integrally connected with a limiting convex. It is intended to limit the pressing cake assembly or the cake carrying assembly.

[0008] Preferably, the cake carrying assembly includes a back plate, cake cylinders are connected to both sides of the back plate, and an oil outlet groove is provided at the bottom of the cake cylinder.

[0009] Preferably, the cake-carrying assembly further includes card seats connected to both sides of the back plate. Slide columns are slidably arranged on the card seats. One end of the slide column is connected with a chuck, and the other end passes through the card seat and is connected with a limit cap. A first spring is sleeved on the slide column, and both ends of the first spring are respectively in contact with the card seat and the chuck; a card slot is arranged on the cake barrel, and the chuck is fitted at the card slot. The chuck clamps the oil cake under the elastic force of the first spring to prevent it from falling off from the cake barrel.

[0010] Preferably, the inner wall of the cake barrel has an inclination.

[0011] Preferably, a vibration cylinder is arranged on the back plate, and a free block is arranged inside. The free block can move freely in the vibration cylinder. With the bottom of the cake-carrying assembly as the center to shake, during the reciprocating shaking process of the cake-carrying assembly, the free block reciprocally impacts the vibration cylinder, and the vibration generated by the impact is conducted to the cake barrel to accelerate the separation of the oil cake from the cake barrel.

[0012] Preferably, the cake-pressing assembly includes a detachable housing with an installation cavity inside. A pressing disc is arranged in the installation cavity. An avoidance groove is arranged on the housing, and the pressing disc is exposed from the housing through the avoidance groove.

[0013] Preferably, the pressing disc is connected to a rotating gear disc. One side of the rotating gear disc is exposed from the housing, and convex stripes are arranged on the pressing disc; a rotating rod, a gearbox and a second motor are arranged on the frame. The rotating rod penetrates through all the bearing seats. One end of the rotating rod is connected to the output end of the gearbox, and the output of the second motor is connected to the input end of the gearbox. Gears with the same number as the cake-pressing assemblies are key-connected to the rotating rod. The gears are located inside the housing and mesh with the rotating gear disc. After the pressing is completed, the pressing disc is driven to rotate. When the pressing disc rotates, the convex stripes on it are engaged with the oil cake under the extrusion force, and the oil cake can be driven to rotate in the cake barrel when rotating, so that the oil cake is separated from the inner wall of the cake barrel.

The chuck on it can pre-position the oil cake during installation, which is more convenient for installation. When pressing the oil, the pressing is carried out through the cake-pressing assemblies on both sides, and the oil extrusion is more efficient; the cake barrel of the cake-carrying assembly is set with an inclination, and the built-in free block can generate vibration. At the same time, the cake-pressing assembly rotates through the rotating gear disc, and the combined action accelerates the separation of the oil cake, no longer relying on tools to pry off the oil cake, and the efficiency is greatly improved.

Detailed Description of the Invention

[0024] Next, a specific embodiment of the present invention will be elaborated in detail with reference to the attached Figures 1 - 6 drawings.

[0025] Referring to the attached Figures 1 - 3 , a tea seed oil pressing device for the production of tea oil includes a machine base 1 for bearing weight. A plurality of first motors 2 are connected to one side of the machine base 1. A screw 3 with the same number as the first motors is horizontally and rotatably arranged on the machine base 1, and the screw 3 is connected to the output shaft of the first motor 2. A slide rail beam 4 is connected to the machine frame 1, and a plurality of bearing seats 5 are slidably arranged on the slide rail beam 4. The bearing seats 5 carry a cake pressing assembly and a cake carrying assembly arranged at intervals. The cake carrying assembly is used for placing the oil cake, and the cake pressing assembly is used for clamping and tightly pressing the oil cake on the oil cake group to make it produce oil.

[0026] A screw sleeve 6 is connected to one side of the bearing seat 5 located at the farthest end away from the first motor 2, and the screw sleeve 6 is matched on the screw rod 3, and the bearing seat 5 at the farthest end and the closest end of the first motor 2 is provided with a cake pressing assembly, and a group of cake carrying assemblies is provided between the cake pressing assemblies. When squeezing out the oil, the first motor 2 starts to drive the screw rod 3 to rotate, and the screw rod drives the farthest cake pressing assembly to approach the first motor, and gradually pushes all the cake pressing assemblies and cake carrying assemblies to approach the motor until they are all tightly fitted, and the subsequent first motor continues to output torque, and the extrusion force between the cake pressing assembly and the cake carrying assembly gradually increases, and the oil cake is squeezed out of the oil. In this embodiment, the first motor 2 is provided with multiple groups, the purpose of which is to disperse the matching load between the screw rod 3 and the farthest bearing seat 5, and also to balance the force on the bearing seat 5.

[0027] Reference Figure 4 The bearing seat 5 is a concave frame with an opening and a slide groove at the bottom. The cake pressing assembly and the cake carrying assembly to be installed are slid sideways into the bearing seat 5 through the opening, which is convenient for installation and disassembly.

[0028] Reference Figure 5 The cake carrying assembly includes a back plate 7, which is provided with a handle groove 701 for people to grab to push the back plate 7 into or pull out of the supporting seat 5. Cake drums 8 are also connected to both sides of the back plate 7. The cake drum 8 is used to accommodate tea oil cakes. An oil outlet groove 801 is provided at the bottom of the cake drum 8. The oil in the tea seeds is stored in the oil bodies of the cells, which are wrapped by the cell walls. After the oil cake is squeezed, the mechanical pressure destroys the cell structure and releases the oil. The oil flows out in liquid form and flows out from the oil groove 801 at the bottom.

[0029] The cake carrying assembly is used to load the oil cake, and load it into the carrying seat 5 together with the oil cake to wait for oil pressing. After oil pressing, the oil cake is taken out and replaced with a new one. Therefore, the cake carrying assembly of this embodiment is also provided with a structure for pre-positioning the oil cake: the back plate 7 is connected with a base 9 on both sides, and a sliding column 10 is slidably provided on the base 9. One end of the sliding column 10 is connected with a clamping head 11, and the other end passes through the base and is connected to a limiting cap 12. A first spring 13 is sleeved on the sliding column 10, and the two ends of the first spring 13 are respectively in contact with the base 9 and the clamping head 11; a clamping groove is provided on the cake cylinder 8, and the clamping head 11 is matched in this clamping groove. When the oil cake needs to be placed, the oil cake is directly pushed into the cake drum 8. The cake drum 8 will squeeze the inclined surface on the clamping head 11 to make the clamping head retreat from the clamping groove, avoiding the oil cake and compressing the first spring 13 at the same time. When the oil cake is pushed into place, the clamping head clamps the oil cake under the elastic force of the first spring to prevent it from falling out of the cake drum. At this time, the oil cake can be installed together with the cake carrier assembly; when the pressing is completed, the oil cake needs to be removed. At this time, the clamping head is pushed to continue to retreat for a distance to release the clamping of the oil cake, so that the oil cake can easily fall out of the cake drum.

[0030] It should be noted that after pressing, the oil cake is tightly compacted in the cake barrel. To further improve the convenience of removing the oil cake, the inner wall of the cake barrel has an inclination, similar to the inclination of a mold during demolding. Further, in this embodiment, the following technical solution is adopted to accelerate the separation of the oil cake from the cake barrel 8 by shaking and knocking: Refer to the attached Figure 6 , a vibration cylinder 14 is provided on the back plate 7. The vibration cylinder 14 is composed of two half cylinders connected by threads and contains a free block 15 which can move freely within the vibration cylinder 14. When it is necessary to remove the oil cake, the cake-carrying assembly can be shaken with the bottom of the cake-carrying assembly as the center. During the reciprocating shaking of the cake-carrying assembly, on the one hand, due to the change in acceleration and the inertia of the cake barrel, there is a tendency for the oil cake to separate from the cake barrel. On the other hand, the reciprocating shaking of the cake-carrying assembly causes the free block 15 to repeatedly impact the vibration cylinder 14, and the vibration generated by the impact is transmitted to the cake barrel, accelerating the separation of the oil cake from the cake barrel and quickly separating under the structural feature of the inclined cake barrel.

[0031] Refer to the attached Figure 4 , the cake-pressing assembly includes a detachable housing 16. Similarly, a handle position is also provided on the housing 16. An installation cavity is provided inside the housing 16, and a pressing plate 17 is provided in the installation cavity. An avoidance groove 161 is provided on the housing 16, and the pressing plate 17 is exposed from the housing 16 at the avoidance groove 161, aiming to be adapted to the cake barrel 8 and extrude the oil cake in the cake barrel.

[0032] The pressing plate 17 is connected to a rotating gear disk 18. One side of the rotating gear disk 18 is exposed from the housing 16, and convex lines 171 are provided on the pressing plate 17. A rotating rod 19, a gearbox 20, and a second motor 21 are further provided on the frame 1. The rotating rod 19 penetrates through all the bearing seats 5, playing a role in guiding and redundant positioning for the bearing seats 5. One end of the rotating rod 19 is connected to the output end of the gearbox 20, and the output of the second motor 21 is connected to the input end of the gearbox 20. A gear 22 with the same number as the cake-pressing assemblies is key-connected to the rotating rod 19. The gear 22 is inside the housing 16 so that it can slide on the rotating rod 19 as the bearing seat 5 slides during oil pressing. The gear 22 meshes with the rotating gear disk 18 and can drive the pressing plate 17 to rotate after pressing is completed. When the pressing plate 17 rotates, the convex lines on it are engaged with the oil cake under the extrusion force and can drive the oil cake to rotate in the cake barrel 8 during rotation, causing the oil cake to separate from the inner wall of the cake barrel.

[0033] Refer to the attached Figure 4, a hook 23 is rotatably connected to the bottom of the bearing seat 5. A torsion spring is connected between the rotating end of the hook 23 and the bearing seat 5. A limiting protrusion 24 is integrally connected to the free end of the hook 23. When installing the cake pressing assembly or the cake loading assembly, place the bottom end of the cake pressing assembly or the cake loading assembly on the sliding groove at the bottom of the bearing seat 5. The cake pressing assembly or the cake loading assembly presses down the limiting protrusion 24 by its own weight, causing the hook 23 to rotate and the torsion spring to store energy. Then, after pushing the cake pressing assembly or the cake loading assembly into place, the hook 23 rotates and resets under the action of the torsion spring, and the limiting protrusion 24 abuts against the side of the sliding groove of the bearing seat 5 to limit the cake pressing assembly or the cake loading assembly.

[0034] Reference appendix Figure 1 , a fixed housing 25 is connected to the frame 1, and an opening housing 26 with a viewing window is also rotatably connected, which serves to isolate the working area during operation.

[0035] The tea seed oil pressing device for tea oil production of the present invention installs the oil cake through a set independent cake loading assembly. The chuck on it can pre-position the oil cake during installation, making the installation more convenient. When pressing the oil, it is pressed by the cake pressing assemblies on both sides, and the extrusion of oil is more efficient; the cake loading assembly is provided with an inclined cake barrel, and the built-in free block can generate vibration. At the same time, the cake pressing assembly rotates through the rotating tooth disc, and the combined action accelerates the separation of the oil cake, no longer relying on tools to pry off the oil cake, and the efficiency is greatly improved.

[0036] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
