Description

Technical Field

[0001] The invention belongs to the technical field of tea oil processing, and in particular relates to a tea oil pressing device. Background Art

[0002] Tea oil is an edible vegetable oil extracted from the mature seeds of the common tea oil plant of the genus Camellia in the family Theaceae. There are usually two methods for producing tea oil. One is chemical pressing (extraction method); the other is physical pressing, which is to place the raw material (the oil cake formed after processing tea seeds) in a sealed container, and then squeeze the tea oil out of the oil cake by mechanical or manual pressure.

[0066] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0067] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0068] Example

[0069] like Figure 1-14As shown, the present application discloses a tea oil pressing device, including a workbench 1, on which are arranged:

[0070] A plurality of pressing cylinders 303, the pressing cylinders 303 can move along an annular track on the workbench 1, and the plurality of pressing cylinders 303 are evenly distributed on the annular track;

[0071] The centrifugal assembly 4 is used to drive the pressing cylinder 303 to rotate around its own axis. Specifically, the centrifugal assembly 4 includes:

[0072] A follower 403, which is disposed on the outer wall of the pressing cylinder 303;

[0073] The active member 402 can drive the multiple driven members 403 to rotate synchronously, so that the multiple pressing cylinders 303 can rotate around their own axes;

[0074] The tea oil pressing device also includes a reversing component 3, which drives the multiple pressing cylinders 303 to move synchronously on the annular track, and realizes the self-rotation of the pressing cylinders 303 through the cooperation of the active member 402 and the driven member 403. It should be noted that while the reversing component 3 drives the multiple pressing cylinders 303 to "revolve" on the annular track with the central axis of the annular track, the driven member 403, driven by the active member 402, ensures the "self-rotation" of the multiple pressing cylinders 303. The purpose of this design has the following advantages:

[0075] The centrifugal filtration effect of the pressing cylinder 303 is fully guaranteed, and the tea oil is separated from the oil cake to the oil collection place of the pressing cylinder 303;

[0076] Different pressing cylinders 303 can be replaced to facilitate corresponding operations.

[0077] Specifically, the reversing component 3 includes:

[0078] A mounting plate 302, a plurality of pressing cylinders 303 are disposed on the mounting plate 302. In this embodiment, the plurality of pressing cylinders 303 are disposed at the end positions of the mounting plate 302;

[0079] The first driving member 301 provides power for the mounting plate 302 to rotate.

[0080] The first driving member 301 is installed on the workbench 1. The first driving member 301 is a driving motor. The output shaft of the first driving member 301 is vertically fixed on the center of gravity of the mounting plate 302. After the first driving member 301 is started, the mounting plate 302 rotates around the axis of the output shaft of the first driving member 301 on the workbench 1 to achieve the purpose of replacing the pressing cylinder 303.

[0081] Furthermore, in order to ensure the safety of loading and unloading without affecting work efficiency, the tea oil pressing device also includes an adjusting component 6, which is used to achieve the "gradual separation" of the follower 403 and the pressing cylinder 303. Specifically, at least one material changing position is provided on the annular track. When the pressing cylinder 303 moves to the material changing position, the adjusting component 6 works to make the follower 403 rotate relative to the pressing cylinder 303. That is, at this time, the pressing cylinder 303 located at the material changing position will gradually stop rotating, while the remaining pressing cylinders 303 still maintain "self-rotation".

[0082] In this embodiment, the adjustment component 6 includes:

[0083] The annular groove 601 and the clamping groove 602 are connected end to end and are arranged around the outer wall of the pressing cylinder 303. The clamping groove 602 is arranged on the outer wall of the pressing cylinder 303. The upper end of the clamping groove 602 is connected to the annular groove 601.

[0084] A guide post 603, the guide post 603 is arranged on the inner wall of the gear ring;

[0085] The first trigger member 604 is arranged on the workbench 1. When the ring gear contacts the first trigger member 604, the ring gear is pushed by the first trigger member 604, so that the ring gear moves in the axial direction, thereby driving the guide column 603 to move from the slot 602 to the annular groove 601, so that the ring gear can rotate relative to the pressing cylinder 303; when the ring gear is separated from the first trigger member 604, the guide column 603 enters the slot 602 from the annular groove 601, and the ring gear is fixed relative to the pressing cylinder 303.

[0086] It should be noted that the reference Figure 8 , Fig. 9 In this embodiment, the first trigger member 604 is preferably an arc-shaped protrusion.

[0087] When the above design is adopted, when the gear ring needs to drive the pressing cylinder 303 to rotate again, the guide column 603 will be subjected to a large instantaneous impact force, resulting in an unsatisfactory service life of the structure. Therefore, in other embodiments, reference Figure 5 , Figure 6 , the regulating component 6 comprises:

[0088] A first friction plate 605, wherein the first friction plate 605 is disposed on the ring gear;

[0089] A second friction plate 606, which is disposed on the pressing cylinder 303;

[0090] The second trigger member 607, after the ring gear contacts the second trigger member 607, moves in the axial direction, so that the first friction plate 605 and the second friction plate 606 fit together, and the ring gear is fixed relative to the pressing cylinder 303; after the second trigger member 607 separates from the ring gear, the first friction plate 605 and the second friction plate 606 separate, and the ring gear rotates relative to the pressing cylinder 303.

[0091] It should be noted that, in this solution, the second trigger member 607 is formed of two arc-shaped protrusions.

[0092] It should be noted that the working mode of the second trigger member 607 is different from that of the first trigger member 604. After the pressing cylinder 303 in this scheme leaves the material changing position, it contacts the second trigger member 607 and is lifted up by the second trigger member 607, so that the first friction plate 605 and the second friction plate 606 are fitted together, thereby realizing the linkage between the ring gear and the pressing cylinder 303 (the working principle of the first trigger member 604 is to lift the pressing cylinder 303 when the pressing cylinder 303 reaches the material changing position, so that the guide column 603 moves from the slot 602 to the annular groove 601, thereby realizing the rotation of the ring gear outside the pressing cylinder 303); therefore, an elastic reset member (such as a spring) can be further provided to act on the ring gear, so that after the pressing cylinder 303 reaches the pressing position, the ring gear can be pushed to move by the action of the elastic reset member, thereby realizing the separation of the first friction plate 605 and the second friction plate 606.

[0093] The main purpose of setting the above-mentioned two adjustment components 6 is to realize the active connection between the ring gear and the pressing cylinder 303, so as to achieve different movement states of multiple pressing cylinders 303 at different points (when changing the material position, the pressing cylinder 303 can be still to ensure safe loading and unloading).

[0094] The tea oil pressing device also includes a pressing component 2, and at least one pressing position is arranged on the annular track. The working end of the pressing component 2 presses the oil cake inside the pressing cylinder 303 located at the pressing position to enhance the oil extraction effect;

[0095] The pressing assembly 2 includes a fixed frame, a lifting member and a pressing head, wherein the fixed frame is vertically fixed on the table surface of the workbench 1, and the lifting member is arranged at the upper end of the fixed frame. The lifting member is a hydraulic cylinder, and the movable end of the lifting member passes through the fixed frame and is connected to the pressing head, so that the pressing head can move on the workbench 1 toward or away from the table surface of the workbench 1; when the oil is separated, the pressing cylinder 303 located at the pressing position can be rotated to the material changing position by starting the first driving member 301 after the lifting member and the pressing head have finished pressing and reset, so as to work. The staff takes out the pressed oil cake from the pressing cylinder 303, and the pressing cylinder 303 originally located at the material changing position is rotated to the pressing position driven by the mounting plate 302 after the staff puts the oil cake to be pressed into it, so as to carry out pressing. During the whole process, even if the lifting parts malfunction, it will not cause accidental injury to the staff who replace the oil cake, thereby achieving the effect of increasing the safety of the tea oil pressing process. At the same time, since the multiple pressing cylinders 303 have different motion states at different points, non-stop loading is realized, which effectively improves the overall work efficiency. How to achieve it specifically will be described in detail later.

[0096] It should be noted that, in order to improve work efficiency, multiple pressing positions can be set up, and accordingly, the number of pressing heads is multiple, and they are fixedly connected to the output end of the lifting member through a plate; in this way, the oil cakes in multiple pressing cylinders 303 can be pressed at the same time, thereby improving work efficiency.

[0097] It should be noted that a pressure cover 3037 may be provided in the pressing cylinder 303, and the pressure cover 3037 may be placed on the upper end of multiple oil cakes. The pressure head acts on the pressure cover 3037 so that the pressure can be evenly transmitted to the oil cakes. Furthermore, a thrust bearing may be provided on the pressure cover 3037, and the pressure head acts on the thrust bearing.

[0098] In this embodiment, the active member 402 is a driving ring, and the driven member 403 is a gear ring. The driving ring includes a driving portion and a mounting portion distributed up and down. The mounting portion and the driving portion are coaxially fixed. The mounting portion is mounted on the workbench 1 by plug-in matching and can rotate around its own axis on the workbench 1. The inner wall of the driving ring is provided with a first transmission tooth 4021, and the outer wall of the gear ring is provided with a second transmission tooth 4031. The first transmission tooth 4021 and the second transmission tooth 4031 are meshed.

[0099] In addition, the centrifugal assembly 4 is also provided with a second driving member 401, and the second driving member 401 is arranged on the workbench 1. The second driving member 401 is a driving motor. A driving wheel is arranged on the output shaft of the second driving member 401, and a conveyor belt 404 is mounted on the driving wheel. The conveyor belt 404 is wound around the outer wall of the driving wheel and the driving part, so that when the second driving member 401 is started, the active member 402 rotates on the workbench 1 and drives the driven member 403 to rotate together, so that the pressing cylinder 303 located at the pressing position can rotate around its own axis on the workbench 1, so that centrifugation can be performed during the pressing process, which allows the tea oil to be thrown out after being pressed out, thereby reducing or avoiding the rebound of the oil cake when the pressure head no longer presses against the oil cake in the filter cylinder 3032, resulting in part of the squeezed oil being sucked back, thereby achieving the effect of increasing the oil yield of the oil cake; it can also ensure the stability of the transmission process.

[0100] At the same time, during the rotation of the mounting plate 302, the two cylinders 3031 located at both ends of the mounting plate 302 rotate around their own axes on the mounting plate 302 at the same time, so that the tea oil inside the cylinder 3031 rotating from the pressing position toward the material changing position will not solidify easily; after the pressing is completed, some of the tea oil attached to the outer wall of the filter cylinder 3032 can be thrown out, so that the squeezed tea oil will not block the filter hole 3034 due to solidification.

[0101] Further, in order to facilitate the collection of the oil produced by centrifugation, the pressing cylinder 303 includes:

[0102] The cylinder 3031 can rotate around its own axis;

[0103] The filter cartridge 3032 is located inside the cylinder body 3031 and is fixedly connected to the cylinder body 3031 . The filter cartridge 3032 is used to place oil cakes. There is a gap between the outer wall of the filter cartridge 3032 and the inner wall of the cylinder body 3031 for collecting oil.

[0104] It should be noted that in order to reduce the friction between the bottom of the cylinder 3031 and the surface of the workbench 1, a plurality of balls are evenly distributed at the bottom of each cylinder 3031 through a ball hinge, which enables the cylinder 3031 to move smoothly on the workbench 1 driven by the mounting plate 302.

[0105] It should be noted that the bottom of the cylinder 3031 is preferably installed in a detachable manner, for example, by achieving a detachable connection through bolts.

[0106] In order to reduce or avoid the situation where the filter cartridge 3032 is deformed due to the downward pressure of the pressure head, a support ring 3033 is provided at the bottom of the cylinder 3031, one end of the support ring 3033 is fixedly connected to the cylinder 3031, and the other end of the support ring 3033 is provided with the lower end of the filter cartridge 3032 to support the filter cartridge 3032, so that when the pressure head presses the oil cake in the filter cartridge 3032, the force applied by the pressure head on the filter cartridge 3032 will not easily cause the filter cartridge 3032 to deform; and a plurality of filter holes 3034 are provided on the side wall of the support ring 3033, and an oil outlet hole 3034 is provided at the bottom of the cylinder 3031 at a position located in the support ring 3033. 036. A sealing member 3035 for sealing the oil outlet hole 3036 is provided at the oil outlet hole 3036, so that the squeezed tea oil can enter the support ring 3033 through the filter hole 3034 on the side wall of the support ring 3033 when it is centrifuged between the outer wall of the filter cartridge 3032 and the inner wall of the cylinder body 3031. When the sealing member 3035 is lifted up from the oil outlet hole 3036, the oil can be taken out from the cylinder body 3031. In this process, in addition to supporting the filter cartridge 3032, the filter hole 3034 of the support ring 3033 itself also plays a secondary filtering role for the squeezed tea oil, so that the debris in the oil cake will not easily flow out from the oil outlet with the tea oil.

[0107] Furthermore, in order to achieve the purpose of non-stop loading, we make certain settings on the mounting plate 302, such as Figure 1 , Figure 2 , Figure 3 The mounting plate 302 shown is a "three-axis structure". It should be noted that the "three-axis structure" in this article only means that the mounting plate 302 has at least three mounting ends for mounting the pressing cylinder 303, or, Figure 8 , Fig. 9 , Fig.10 , Fig.11 The mounting plate 302 is a split structure, and the specific design can be reasonably arranged according to the actual situation.

[0108] In order to facilitate understanding of the changes in the motion state of the device at different points, we choose the mounting plate 302 as a split structure for illustration; first, the mounting plate 302 includes a first mounting plate body 3021 and a second mounting plate body 3022, the first mounting plate body 3021 is hinged to the second mounting plate body 3022, and the driving end of the first driving member 301 is fixed at the hinge. Specifically, the driving end of the first driving member 301 is fixed to one of the first mounting plate body 3021 and the second mounting plate body 3022, so that one of the first mounting plate body 3021 and the second mounting plate body 3022 can rotate along the hinge.

[0109] When in use, by pulling the pressing cylinder that needs to be discharged, the gear ring is brought into contact with the first trigger member 604, the gear ring is lifted by the first trigger member 604, and the gear ring drives the guide column 603 to move upward, thereby realizing the position change of the gear ring and the pressing cylinder 303. More specifically, the gear ring is in contact with the first trigger member 604, pushing the guide column 603 to move from the slot 602 to the annular groove 601. At this time, the gear ring is idling and will not drive the pressing cylinder 303 to rotate. At this time, safe discharge and loading can be carried out; after loading is completed, the pressing cylinder is pulled to separate the first trigger member 604 from the gear ring, and the gravity of the gear ring drives the guide column 603 to move downward, and the guide column 603 enters the slot 602 from the annular groove 601. The guide column 603 abuts against the slot 602, so that the gear ring can drive the pressing cylinder 303 to rotate, thereby realizing the initial centrifugal action on the newly filled material in the pressing cylinder 303.

[0110] It should be noted that, while changing positions, the two pressing cylinders 303 keep rotating around their own central axes to ensure that the oil is centrifugally thrown out of the oil cake as much as possible. Secondly, the pressed cylinders 303 after the change of position can perform the above-mentioned state switching again to realize discharging and loading. Therefore, the present invention ensures continuity and safety during the working process by optimizing its structure.

[0111] It is worth noting that from the perspective of the entire process, when the equipment is initially used, there is no need to adjust the position of the first mounting plate body 3021 and the second mounting plate body 3022 (i.e., to realize the action of rotating one of the two around the hinge), and the first driving member 301 is sufficient to drive the two to exchange positions for loading. During the pressing process, the above process needs to be adopted to ensure the coordination of the entire process of loading, preliminary centrifugation, secondary centrifugal pressing and discharging. In other words, the entire working process is carried out without stopping, thereby ensuring that the working efficiency of the equipment can be improved.

[0112] Furthermore, an oil extraction hole 101 is provided on the workbench 1, and an oil extraction assembly 5 is provided on the lower surface of the workbench 1; a plugging member 3035 is provided in the pressing cylinder 303, and the plugging member 3035 includes a limit plate 30351, a connecting rod 30352 and a plug 30353, wherein the limit plate 30351 is located in the filter cartridge 3032 and at the bottom of the filter cartridge 3032, and one end of the connecting rod 30352 passes through the filter cartridge 3032 and abuts against the limit plate 30351, The other end of the connecting rod 30352 is provided with a plug 30353, which blocks the oil outlet hole 3036 at the bottom of the cylinder 3031 in a natural state (due to the effect of gravity); after the oil outlet hole 3036 on the cylinder 3031 coincides with the oil extraction hole 101 on the workbench 1, the oil extraction component 5 is started to lift up the plug 30353 that blocks the oil outlet hole 3036, so that the tea oil in the cylinder 3031 can flow out through the oil outlet hole 3036.

[0113] The support ring 3033 supports the bottom of the filter cartridge 3032 to reduce the probability of the filter cartridge 3032 being squeezed and deformed by the pressure head. At the same time, the plug 30353 and the connecting rod 30352 support the limit plate 30351, thereby sharing the load for the support ring 3033. It should be noted that even if the limit plate 30351 does not support the load applied by the pressure head, the plug 30353 will always abut against the inner wall of the oil outlet 3036 in the cylinder 3031 under the natural state, that is, under the action of its own gravity, thereby achieving the blockage of the oil outlet 3036.

[0114] The oil extraction assembly 5 includes a mounting frame 501, a pusher 502, a push rod 503, a driving block 504 and a collecting box, wherein the mounting frame 501 is arranged on the workbench 1 and is located below the oil extraction hole 101, and the push rod 503 is vertically arranged on the mounting frame 501, and the cross-section of the push rod 503 is rectangular, so that the push rod 503 can slide up and down along its own axis on the mounting frame 501 and will not rotate around its own axis. After the upper end of the push rod 503 passes through the oil extraction hole 101 and the oil outlet hole 3036, the plug 30353 is lifted up, so that the plug 30353 no longer blocks the oil outlet hole 3036. At this time, tea oil will flow out from the oil outlet hole 3036 and flow along the The push rod 503 flows downward, and in addition to removing the plug 30353, the push rod 503 also guides the tea oil in the cylinder 3031. At the same time, since the plug 30353 is lifted by the push rod 503, the limit plate 30351 is simultaneously lifted in the filter cartridge 3032, and then the squeezed oil cake is pushed out of the filter cartridge 3032. This makes it unnecessary for the staff to put their hands into the filter cartridge 3032 to take out the oil cake in the filter cartridge 3032, thereby achieving the effect of improving the efficiency of oil cake replacement and reducing the possibility of the staff's arms being contaminated with tea oil or accidentally contacting the inner wall of the filter cartridge 3032 when replacing the oil cake, thereby reducing the possibility of subsequent tea oil contamination.

[0115] The lower end of the push rod 503 is provided with a wedge block 5031, and the wedge block 5031 is provided with a first wedge surface, and the pushing member 502 is arranged on the lower surface of the workbench 1, the pushing member 502 is a cylinder, and the driving block 504 is installed at the movable end of the pushing member 502, and the driving block 504 is provided with a second wedge surface that can fit with the first wedge surface. When the pushing member 502 is started, the movable end of the pushing member 502 extends out, so that the wedge block 5031 on the push rod 503 slides along the second wedge surface, thereby realizing the rise of the push rod 503; and when the pushing member 502 returns to the initial position, the wedge block 5031 on the push rod 503 slides in the opposite direction along the second wedge surface, thereby realizing the descent of the push rod 503, and the collection box is located below the mounting frame 501, and is used to collect the outflowing tea oil.

[0116] It should be noted that, in order to reduce the contamination of tea oil, a through hole 102 is provided on one side of the oil extraction hole 101, and the other end of the through hole 102 extends out of the side wall of the workbench 1, so as to achieve oil discharge. It is worth mentioning that, since a small amount of tea oil will flow through the wedge block 5031 and the driving block 504, the tea oil can also lubricate the wedge block 5031 and the driving block 504, reduce the friction between the first wedge surface on the wedge block 5031 and the second wedge surface on the driving block 504, thereby reducing the degree of wear between the first wedge surface and the second wedge surface, and achieving the effect of protecting the wedge block 5031 and the driving block 504.

[0117] The implementation principle of the present application is: the oil cakes are stacked and placed in the filter cartridge 3032 at the material changing position, and then the first driving member 301 is started, so that the filter cartridge 3032 at the material changing position moves toward the pressing position, while the filter cartridge 3032 originally at the pressing position moves toward the direction of the material changing position.

[0118] When the filter cartridge 3032 filled with oil cake is in the pressing position, the first driving member 301 stops moving, the lifting member starts, and then drives the pressure head to move toward the filter cartridge 3032. During the lowering of the lifting member, the staff fills the filter cartridge 3032 which is in the material changing position with oil cake. It should be noted that the filter cartridge 3032 in the material changing position is in a non-rotating state at this time, so as to ensure safe operation; at this time, the remaining pressing cylinders 303 rotate around their axes driven by the driving ring, and the tea oil squeezed out of the filter cartridge 3032 is centrifuged through rotation, so that the oil in the filter cartridge 3032 can be thrown out to the gap between the inner wall of the cylinder body 3031 and the outer wall of the filter cartridge 3032.

[0119] When the squeezing is completed, the first driving member 301 is started again, so that the filter cartridge 3032 located at the squeezing position at this time rotates toward the material changing position. It is worth mentioning that in the process of the filter cartridge 3032 moving toward the material changing position, since the driven member 403 moves outside the active member 402, the cylinder 3031 will rotate around its own axis during the movement, so that the tea oil adhering to the outer wall of the filter cartridge 3032 can be thrown out, while also reducing the possibility of the squeezed tea oil solidifying. When the filter cartridge 3032 moves to the material changing position, the filter cartridge 3032 stops rotating through the action of the adjusting component 6; and the filter cartridge 3032 that was previously at the material changing position is filled with oil cakes and then reaches When the pressing position is reached and the pressing is carried out through the pressing component 2, the pressure head is inserted into the filter cartridge 3032 to fix the pressing cartridge 303 on the pressing position; at this time, the oil extraction component 5 can be started to move the plug 30353 in the cylinder 3031 on the material change position away from the oil outlet 3036. At the same time, the limit plate 30351 in the filter cartridge 3032 rises synchronously, so that the pressed oil cake can be ejected from the filter cartridge 3032 to facilitate replacement by the staff. The oil flows down through the push rod 503 after being filtered, and finally gathers in the collection box after passing through the through hole 102. This process is repeated until the pressing of all the oil cakes is completed.
