Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of edible oil production equipment, and particularly relates to an edible oil production system. BACKGROUND

[0002] The edible oil filling machine generally adopts flow meter type filling. The flow meter type filling is computer automatic tracking oil temperature and density change to adjust oil delivery quantity at any time, so that the oil delivery quality error caused by the change of temperature and density is reduced, the metering accuracy is high, and the edible oil can be quickly filled through the edible oil filling machine, so that the edible oil production and processing speed is faster. However, the filling machine cannot well move and transport the filling bottles when filling the edible oil.

[0003] The utility model discloses a kind of filling machines for edible oil production, and relates to filling machine structure technical field, to solve the problem that existing filling machine for edible oil production cannot well transport edible oil filling bottle, so that filling bottle is prone to dump in the process of moving. The inside of filling device box is equipped with electric cylinder, the lower portion of electric cylinder is equipped with moving mounting seat, the front end of moving mounting seat is equipped with filling head, the lower portion of filling head is equipped with transport device frame, the upper portion of transport device frame is equipped with fixing device, the upper portion of fixing device is equipped with fastening device, the inside of fixing device is provided with limit sliding slot, one end of limit sliding slot is equipped with moving sliding rod, one side of moving sliding rod is equipped with mounting plate, one side of mounting plate is provided with connecting rod, one side of connecting rod is equipped with limit sliding rod, the lower portion of transport device frame is equipped with support device.

[0004] The filling head of the filling machine is closed by the valve rod after filling is completed, but there is still some oil at the end of the valve rod, which may drip outside the oil bottle. In the prior art, the valve rod is provided with a hollow structure and connected to an oil pumping mechanism through a hose, which pumps the residual oil at the end of the valve rod away from the center of the valve rod.

[0005] However, the above oil return method needs to separately set up an external oil pumping mechanism, which not only has a complex structure but also increases the cost of equipment layout. In addition, how to control the operation of the oil pumping mechanism when the valve rod is closed and pump the residual oil away in time is also a problem to be solved. SUMMARY

[0006] To solve the above problems in the prior art, the purpose of the present application is to provide an edible oil production system capable of automatically and synchronously pumping away residual oil at the end of the valve rod.

[0007] The technical solution adopted by the present application is as follows:

[0008] The cam is connected to the valve body through the cam, and the cam is connected to the valve body through the cam, and the cam is connected to the valve body through the cam.

[0009] When the edible oil is filled, the cylinder's piston rod drives the valve stem upward, closing the filling cylinder's outlet. At this point, the valve stem drives the driving gear upward. Driven by the active rack, the coaxial gear train rotates, and the large gear drives the passive rack. Because the active and passive racks are located on the same side of the coaxial gear train, they move in the same direction. Because the small gear meshes with the active rack and the large gear meshes with the passive rack, the passive rack moves at a greater distance (speed) than the active rack. Consequently, as the lifting rod drives the piston plate upward, the distance between the piston plate and the diaphragms increases, creating a negative pressure in the space between them. The diaphragms bend upward under this negative pressure, opening the valve stem port. Any remaining edible oil at the stem tip is drawn into the space between the piston plate and the diaphragms by the negative pressure. When the valve stem fully closes the filling cylinder's opening, the lifting rod stops moving, the diaphragms return to their original positions, and the remaining edible oil is temporarily stored in the space between the piston plate and the diaphragms.

[0010] When filling again, the cylinder drives the valve stem to descend, and the end of the valve stem opens the opening of the filling cylinder. The space between the piston plate and several diaphragms is reduced, and several diaphragms bend downward. The end of the valve stem is opened, and the temporarily stored edible oil is discharged into the oil bottle.

[0011] The power of the valve stem of the present invention drives the lifting rod to move in the same direction, and the moving distance is amplified by the lifting drive mechanism, so that the space between the piston plate and the plurality of diaphragms is opened and negative pressure is formed during the process of closing the filling cylinder opening, thereby automatically extracting the residual edible oil without the need for an external oil extraction mechanism. The lifting drive mechanism acts as a transmission mechanism, so that the movement of the lifting rod and the valve stem is always synchronized, ensuring that the residual edible oil is extracted as soon as the opening of the filling cylinder is closed, and minimizing the dripping of the residual edible oil. In addition, during the process of opening the filling cylinder opening, the temporarily stored edible oil can be discharged into the oil bottle under the downward thrust of the lifting rod, preventing the residual edible oil from staying in the space between the piston plate and the plurality of diaphragms for a long time and causing deterioration.

[0012] As a preferred embodiment of the present invention, the upper end of the valve stem is provided with an elongated hole, and a connecting rod is connected between the passive rack and the lifting rod, and the connecting rod passes through the elongated hole. The connecting rod is passed out of the elongated hole, so that the lifting rod moves together with the passive rack and is not blocked by the valve stem.

[0013] As a preferred embodiment of the present invention, a slide groove is installed on the frame, and the passive rack is sleeved in the slide groove. The slide groove can guide the passive rack, ensure the stability of the passive rack during movement, and correspondingly improve the stability of the lifting rod during movement.

[0014] As a preferred embodiment of the present invention, both sides of the lifting rod are provided with lifting drive mechanisms. When both sides are provided with lifting drive mechanisms, the lifting rod can move more smoothly, avoid lifting deviation, and ensure that the piston plate moves smoothly in the valve stem.

[0015] As a preferred embodiment of the present invention, the lower end of the valve stem forms a valve head, the upper and lower sides of which are both conical surfaces. The inner side of the filling cylinder outlet is conical and mates with the conical surface on the upper side of the valve head. The conical surface on the inner side of the filling cylinder outlet mates with the conical surface on the upper side of the valve head, increasing the contact area and ensuring the valve head's ability to reliably close the filling cylinder opening.

[0016] As a preferred embodiment of the present invention, the filling cylinder includes a buffer cylinder and an oil discharge cylinder, which are interconnected. The inner diameter of the buffer cylinder is larger than that of the oil discharge cylinder. The buffer cylinder has a larger space, allowing for a larger amount of edible oil to be held. The smaller inner diameter of the oil discharge cylinder allows for accurate control of the filling and oil discharge speed.

[0017] As a preferred embodiment of the present invention, the oil extraction system includes a weighing sensor, an oil tank and an oil pump installed on a frame, and an oil barrel is installed on the weighing sensor; it also includes a three-way joint, an oil inlet pipeline is connected between the first interface of the three-way joint and the oil tank, a valve is connected to the oil inlet pipeline, the second interface of the three-way joint is connected to the inlet and outlet pipelines, the other end of the inlet and outlet pipelines extends into the oil barrel, the third interface of the three-way joint is connected to the oil outlet pipeline, the other end of the oil outlet pipeline is connected to the filling barrel, and the oil pump is connected to the oil outlet pipeline.

[0018] When oil needs to be added to the oil cylinder, the valve is opened, and the oil in the tank is added to the cylinder through the oil inlet pipe, the tee joint, and the inlet and outlet pipes. When filling is required, the oil pump is started, and the oil in the oil cylinder flows through the inlet and outlet pipes, the tee joint, the oil pump, and the oil outlet pipe into the filling cylinder. A load cell weighs the oil cylinder in real time, ensuring precise filling. Because the oil inlet and outlet pipes are both connected to the oil cylinder and only extend into the oil cylinder without being fixed to the oil cylinder, the weight and vibration of the inlet and outlet pipes do not affect the oil cylinder, thus ensuring the accuracy of the load cell weighing the oil cylinder and improving filling precision.

[0019] As a preferred embodiment of the present invention, a floating block is installed within the oil cylinder. The inlet and outlet pipes are connected to the floating block, with the ends of the inlet and outlet pipes extending below the floating block. A fixed head is installed on the frame, securing the inlet and outlet pipes to the fixed head, which is located above the oil cylinder. The floating block always floats above the oil surface, while the ends of the inlet and outlet pipes extend below the floating block. This allows the inlet and outlet pipes to remain immersed in the oil, preventing air from entering the pipes and ensuring smooth oil extraction. The inlet and outlet pipes are connected to the floating block and fixed head, respectively, and the fixed head is located above the oil cylinder, preventing the inlet and outlet pipes from contacting the oil cylinder, further improving the accuracy of the load cell.

[0020] As a preferred embodiment of the present invention, the upper and lower edges of the floating block are rounded, and rollers are mounted on its sides. When the floating block contacts the inner wall of the oil cylinder, the rollers roll along the inner wall, reducing friction, minimizing the impact of the floating block on the oil cylinder, and ensuring that the floating block always floats above the oil surface.

[0021] As a preferred embodiment of the present invention, a support frame is fixed to the frame, and the tee joint is mounted on the support frame. The support frame reliably supports the tee joint, reducing vibration transmitted to the inlet and outlet pipes, thereby further reducing the impact of the inlet and outlet pipes and the floating block on the oil cylinder.

[0022] The beneficial effects of the present invention are:

[0023] 1. The power of the valve stem in this invention drives the lifting rod to move in the same direction, and the lifting drive mechanism amplifies this movement. This opens the space between the piston plate and the diaphragms during the closing of the filling cylinder opening, creating a negative pressure and automatically extracting any remaining cooking oil. This eliminates the need for an external extraction mechanism. The lifting drive mechanism acts as a transmission mechanism, ensuring that the movement of the lifting rod and valve stem is always synchronized, ensuring that any remaining cooking oil is extracted immediately after the filling cylinder opening is closed, minimizing dripping. Furthermore, during the opening of the filling cylinder, the downward thrust of the lifting rod allows any temporarily stored cooking oil to drain into the oil bottle, preventing any residual cooking oil from lingering in the space between the piston plate and the diaphragms and potentially deteriorating.

[0024] 2. Oil flow into and out of the oil reservoir is via inlet and outlet pipes, which extend only into the reservoir without being fixed to it. The floating block always floats above the oil level, while the ends of the inlet and outlet pipes extend below the floating block. This ensures that the pipes remain submerged in the oil, preventing air from entering the pipes and ensuring smooth oil extraction. The inlet and outlet pipes are connected to the floating block and fixed head, respectively, with the fixed head positioned above the reservoir. This prevents the pipes from contacting the reservoir, preventing their weight and vibration from affecting the reservoir, thus improving the accuracy of the load cell.

DETAILED DESCRIPTION

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of 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. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0034] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. It should be noted that the embodiments of the present invention and the features therein may be combined with each other unless there is a conflict.

[0035] like Figures 1 to 7 As shown, the edible oil production system of this embodiment includes a frame 1, an oil extraction system 2 is installed on the frame 1, and the oil outlet of the oil extraction system 2 is connected to a filling cylinder 3, which is installed on the frame 1. A valve stem 4 for opening or closing the outlet of the filling cylinder 3 is provided in the filling cylinder 3; a cylinder 5 is also installed on the frame 1, and the piston rod of the cylinder 5 is connected to the valve stem 4. The valve stem 4 is a hollow structure, and a plurality of diaphragms 41 are connected to the lower end opening of the valve stem 4. The plurality of diaphragms 41 are spliced ​​together to close the lower end opening of the valve stem 4. A piston plate 42 is provided in the valve stem 4, and the piston is connected to The lifting rod 43 is connected to a lifting drive mechanism 6 for driving the lifting rod 43 to move, and the lifting drive mechanism 6 is installed on the frame 1; the lifting drive mechanism 6 includes an active rack 61 fixed on the valve stem 4, a coaxial gear set installed on the frame 1 and a passive rack 62 fixed to the lifting rod 43, the coaxial gear set includes a large gear 63 and a small gear 64 fixed to each other, the small gear 64 is engaged with the active rack 61, the large gear 63 is engaged with the passive rack 62, and the active rack 61 and the passive rack 62 are located on the same side of the coaxial gear set.

[0036] After the edible oil is filled, the piston rod of the cylinder 5 drives the valve stem 4 upward to close the outlet of the filling barrel 3. At this point, the valve stem 4 drives the driving gear upward. Driven by the active rack 61, the coaxial gear train rotates, and the large gear 63 drives the passive rack 62. Because the active rack 61 and the passive rack 62 are located on the same side of the coaxial gear train, the active rack 61 and the passive rack 62 move in the same direction. Because the small gear 64 meshes with the active rack 61 and the large gear 63 meshes with the passive rack 62, the passive rack 62 moves at a greater distance (speed) than the active rack 61. Consequently, when the lifting rod 43 drives the piston plate 42 upward, the distance between the piston plate 42 and the plurality of diaphragms 41 increases, creating a negative pressure in the space between the piston plate 42 and the plurality of diaphragms 41. The negative pressure causes the diaphragms 41 to bend upward, opening the port of the valve stem 4. The edible oil remaining at the end of the valve stem 4 is drawn into the space between the piston plate 42 and the plurality of diaphragms 41 by the negative pressure. When the valve stem 4 completely closes the opening of the filling cylinder 3 , the lifting rod 43 stops moving, the diaphragms 41 return to their original positions, and the remaining cooking oil is temporarily stored in the space between the piston plate 42 and the diaphragms 41 .

[0037] When filling is performed again, the cylinder 5 drives the valve stem 4 to descend, and the end of the valve stem 4 opens the opening of the filling cylinder 3. The space between the piston plate 42 and the plurality of diaphragms 41 is reduced, and the plurality of diaphragms 41 bend downward, the end of the valve stem 4 is opened, and the temporarily stored edible oil is discharged into the oil bottle.

[0038] The power of the valve stem 4 of the present invention drives the lifting rod 43 to move in the same direction, and the moving distance is amplified by the lifting drive mechanism 6, so that the space between the piston plate 42 and the plurality of diaphragms 41 is opened and negative pressure is formed during the process of closing the opening of the filling cylinder 3, thereby automatically extracting the residual edible oil, without the need for an external oil extraction mechanism. The lifting drive mechanism 6 acts as a transmission, so that the movement of the lifting rod 43 and the valve stem 4 is always synchronized, ensuring that the residual edible oil is extracted as soon as the opening of the filling cylinder 3 is closed, and the residual edible oil is minimized from dripping. In addition, during the process of opening the filling cylinder 3, the downward thrust of the lifting rod 43 can drain the temporarily stored edible oil into the oil bottle, preventing the residual edible oil from staying in the space between the piston plate 42 and the plurality of diaphragms 41 for a long time and causing deterioration.

[0039] The upper end of the valve stem 4 is provided with a long hole 44, and a connecting rod 65 is connected between the passive rack 62 and the lifting rod 43, and the connecting rod 65 passes through the long hole 44. The connecting rod 65 is passed out of the long hole 44, so that the lifting rod 43 moves together with the passive rack 62 without being blocked by the valve stem 4.

[0040] The frame 1 is provided with an intermediate plate 13. The filling barrel 3 is mounted on the lower end of the filling barrel 3. The intermediate plate 13 seals the upper end of the filling barrel 3. The upper end of the valve stem 4 passes through the intermediate plate 13. A sealing ring is provided between the valve stem 4 and the intermediate plate 13. The lifting drive mechanism 6 is mounted on the upper side of the intermediate plate 13.

[0041] The diaphragms 41 may be in a fan shape, with the larger ends of the diaphragms 41 fixed to the inner wall of the valve stem 4 . The fan-shaped diaphragms 41 are assembled into a circle to close the lower opening of the valve stem 4 .

[0042] The frame 1 is provided with a slide 66, and the passive rack 62 is sleeved in the slide 66. The slide 66 can guide the passive rack 62, ensure the stability of the passive rack 62 when moving, and correspondingly improve the stability of the lifting rod 43 during movement.

[0043] In this embodiment, both sides of the lifting rod 43 are provided with a lifting drive mechanism 6. When both sides are provided with a lifting drive mechanism 6, the lifting action of the lifting rod 43 is more stable, avoiding the lifting deviation, and ensuring that the piston plate 42 moves smoothly in the valve stem 4.

[0044] The lower end of the valve stem 4 is a valve head 45, the upper and lower sides of which are conical surfaces, and the inner side of the outlet of the filling cylinder 3 is a conical surface matching the upper side of the valve head 45. The conical surface of the inner side of the outlet of the filling cylinder 3 matches the upper side of the valve head 45, increases the contact area, and ensures the reliability of the valve head 45 closing the opening of the filling cylinder 3.

[0045] The filling cylinder 3 comprises a buffer cylinder 31 and an oil discharging cylinder 32 connected to each other, and the inner diameter of the buffer cylinder 31 is larger than that of the oil discharging cylinder 32. The buffer cylinder 31 has a larger space and can contain more edible oil. The inner diameter of the oil discharging cylinder 32 is smaller, and the filling oil speed can be accurately controlled.

[0046] Specifically, the oil taking system 2 comprises a weighing sensor 21, an oil tank 22 and an oil pump 23 installed on the frame 1, the weighing sensor 21 is installed with an oil cylinder 24; a three-way joint 25 is further included, an oil inlet pipeline 26 is connected between the first interface of the three-way joint 25 and the oil tank 22, a valve is connected on the oil inlet pipeline 26, an inlet and outlet pipeline 27 is connected to the second interface of the three-way joint 25, the other end of the inlet and outlet pipeline 27 extends into the oil cylinder 24, an oil outlet pipeline 28 is connected to the third interface of the three-way joint 25, the other end of the oil outlet pipeline 28 is connected with the filling cylinder 3, and the oil pump 23 is connected to the oil outlet pipeline 28.

[0047] When it is needed to add oil into the oil cylinder 24, the valve is opened, and the oil in the oil tank 22 is added into the oil cylinder 24 through the oil inlet pipeline 26, the three-way joint 25 and the inlet and outlet pipeline 27. The position of the oil tank 22 is higher than that of the oil cylinder 24, so that the edible oil enters the oil cylinder 24 under the action of gravity. A pump can also be installed on the oil inlet pipeline 26 or the inlet and outlet pipeline 27 to pump the edible oil in the oil tank 22 into the oil cylinder 24.

[0048] When it is needed to fill, the oil pump 23 is started, and the oil in the oil cylinder 24 enters the filling cylinder 3 through the inlet and outlet pipeline 27, the three-way joint 25, the oil pump 23 and the oil outlet pipeline 28. The weighing sensor 21 weighs the oil cylinder 24 in real time, so as to realize accurate filling. Since the oil inlet and outlet of the oil cylinder 24 are both through the inlet and outlet pipeline 27, and the inlet and outlet pipeline 27 only extends into the oil cylinder 24 without being fixedly connected with the oil cylinder 24, the weight and vibration of the inlet and outlet pipeline 27 will not affect the oil cylinder 24, so as to ensure the accuracy of the weighing of the oil cylinder 24 by the weighing sensor 21, and improve the filling accuracy.

[0049] Furthermore, a floating block 29 is installed within the oil cylinder 24. The inlet and outlet pipes 27 are connected to the floating block 29, with their ends extending below the floating block 29. A fixed head 11 is installed on the frame 1, securing the inlet and outlet pipes 27 to the fixed head 11, which is located above the oil cylinder 24. The floating block 29 always floats above the oil surface, while the ends of the inlet and outlet pipes 27 extend below the floating block 29. This allows the inlet and outlet pipes 27 to always be immersed in the oil, preventing air from entering the pipes and ensuring smooth oil extraction. The connection between the inlet and outlet pipes 27 and the fixed head 11, respectively, and the position of the fixed head 11 above the oil cylinder 24, prevents them from contacting the oil cylinder 24, further improving the accuracy of the load cell 21. The floating block 29 can be made of foam.

[0050] The upper and lower edges of the floating block 29 are rounded, and several rollers are mounted on the sides of the floating block 29. When the floating block 29 contacts the inner wall of the oil cylinder 24, the rollers roll along the inner wall of the oil cylinder 24, reducing friction and minimizing the impact of the floating block 29 on the oil cylinder 24, while ensuring that the floating block 29 always floats above the oil surface.

[0051] A support frame 12 is fixed to the frame 1, and a tee joint 25 is mounted on the support frame 12. The support frame 12 reliably supports the tee joint 25, reducing the vibration transmitted to the inlet and outlet pipes 27, thereby further reducing the impact of the inlet and outlet pipes 27 and the floating block 29 on the oil cylinder 24.

[0052] The present invention is not limited to the above-mentioned optional implementation modes. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that falls within the scope defined by the claims of the present invention falls within the scope of protection of the present invention.
