Description

Technical Field

[0001] The invention relates to the technical field of presses, in particular to a continuous pressing device for peanut oil production. Background Art

[0002] Peanut oil is a vegetable oil extracted from peanuts. It is one of the commonly used edible oils in the daily diet of Chinese residents. Peanut oil pressing equipment is mainly used to extract oil from peanuts. Traditional equipment mostly uses hydraulic pressing to crush the peanut kernels and extract oil through mechanical pressure. Modern equipment is mainly based on screw oil presses, which use the propulsion and extrusion of the screw shaft to separate the oil from the cake after high-temperature steaming and frying. It has the characteristics of high efficiency and stable oil yield.

[0003] In the prior art, a Chinese patent document with publication number CN111718792A discloses an edible oil press with a multi-stage filtering device and a method, which proposes a pressing device, including a support box, a fixed seat welded on the right side of the top of the support box, a support column welded on the left side of the top of the support box, and the tops of the support column and the fixed seat are both connected to a screw press body, a connecting pipe is provided at the oil outlet of the screw press body, a first filter screen is provided on the top of the connecting pipe, a first discharge trough is hinged on the left side of the fixed seat through a pin shaft, and the first discharge trough is located below the connecting pipe, a first drive assembly is connected to the front and rear ends of the left side of the fixed seat, and a second drive assembly is connected to the first drive assembly. Only by working the first drive assembly, the production efficiency of edible oil can be improved and the effect of fragrance diffusion and deodorization can be achieved, effectively saving energy.

[0004] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the feeding component of the pressing device adopts a traditional funnel-type structure design. During operation, the material to be pressed is poured into the funnel, and the material is automatically discharged by its own gravity. However, this structure has significant technical defects in continuous operation. On the one hand, due to the lack of a flow control mechanism, the discharge speed depends entirely on the material stacking height and fluidity. It is easy for a large amount of material to instantly flow into the pressing component, resulting in a sudden increase in the operating pressure of core components such as the pressing roller, and even causing mechanical overload. On the other hand, when the moisture content and particle size of the material are uneven, it is easy to form a blockage at the neck of the funnel due to the increase in mutual friction, resulting in slow or even stagnant discharge, causing the pressing component to idle. The above problems not only reduce the pressing efficiency, but also aggravate equipment wear due to load fluctuations, affecting the continuous and stable operation of the device. Summary of the invention

[0005] The technical problem to be solved by the present invention is that in the prior art, the feeding component of the pressing device adopts a gravity feeding method, and its feeding speed is uncontrollable and easily overloaded or too little.

Detailed implementation manners

[0020] It is easy to understand that according to the technical solution of the present invention, without changing the essence of the present invention, those of ordinary skill in the art can propose various interchangeable structural forms and implementation manners. Therefore, the following detailed implementation manners and the accompanying drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as the whole of the present invention or as a limitation or restriction on the technical solution of the present invention.

[0021] Referring to Figures 1 to 8 as shown, the present invention provides a technical solution: a continuous pressing device for peanut oil production, including a pressing unit and a feeding unit; The pressing unit includes a machine base 11, a driving mechanism 12, a driving rod 13, a pressing mechanism 14, a feeding hopper 15 and a belt transmission mechanism 16. The feeding hopper 15 is fixedly arranged on the upper surface of the end of the pressing mechanism 14. The driving rod 13 is fixedly connected to the end of the driving mechanism 12 and is connected to the pressing mechanism 14. The belt transmission mechanism 16 includes a driving wheel, a driven wheel and a belt, and the driving wheel and the driven wheel are meshed and connected by the belt; The feeding unit includes a central rod 21 movably inserted through the top end of the feeding hopper 15. The inner wall of the feeding hopper 15 is fixedly connected with a hollow cylinder 22. A material distributing wheel 23 is arranged inside the hollow cylinder 22. A speed regulation component is arranged on the side of the feeding hopper 15, and a pushing component is arranged on the outer surface of the hollow cylinder 22.

[0022] By pouring the prepared peanut granules for oil extraction into the feeding hopper 15, then turning on the driving mechanism 12, the pressing mechanism 14 is driven to operate under the drive of the driving rod 13. The peanut granules in the feeding hopper 15 will continuously enter the end of the pressing mechanism 14. After being screw-extruded by the pressing mechanism 14, the oil will flow out and be collected, and the residue will be discharged at the end, which can be used as a nutrient. During the rotation of the driving rod, the speed regulating assembly will be driven to operate through the belt transmission mechanism 16. After being speed-varied by the speed regulating assembly, the feeding unit is driven to operate. With the auxiliary effect of the pushing assembly, the purpose of indirect and uniform feeding is achieved, avoiding the situation of too much or too little material that may occur during continuous feeding, and achieving the effect of controllable feeding rate.

[0023] Refer to Figures 3 to 5 As shown, the central rod 21 movably penetrates through the upper surface of the hollow cylinder 22 and is fixedly connected to the material distributing wheel 23. The outer surface of the material distributing wheel 23 is slidably connected to the inner wall of the hollow cylinder 22. A feeding port 25 is formed through the side of the hollow cylinder 22. Grooves 24 are formed on the outer surface of the material distributing wheel 23, and the width of the grooves 24 is the same as that of the feeding port 25. A transmission rod 26 is movably inserted through the side of the feeding hopper 15. A first bevel gear 27 is fixedly connected to the end of the transmission rod 26 extending into the feeding hopper 15. A second bevel gear 28 is fixedly sleeved on the outer surface of the central rod 21. The first bevel gear 27 is meshed with the second bevel gear 28.

[0024] Under the cooperation of the belt transmission mechanism 16 and the speed regulating assembly, the transmission rod 26 rotates at a stable speed. Through the vertical meshing transmission of the first bevel gear 27 and the second bevel gear 28, the power is transmitted to the central rod 21, causing it to generate a synchronous rotational motion. When the central rod 21 rotates, the material distributing wheel 23 in the hollow cylinder 22 is driven to rotate synchronously. The symmetrically arranged grooves 24 on both sides of the material distributing wheel 23 form a quantitative material storage unit. When the grooves 24 on the outer surface of the material distributing wheel 23 rotate to be precisely aligned with the feeding port 25, the peanut granules in the feeding hopper 15 enter the grooves 24 orderly under the action of gravity. At the same time, the bottom of the grooves 24 is aligned with the lower hole of the feeding hopper 15, enabling the peanut granules to smoothly fall into the pressing mechanism 14. Since the grooves 24 are designed with standardized dimensions, the single-time material storage amount is strictly limited within a scientific range, ensuring the consistency of each feeding amount. When the material distributing wheel 23 continues to rotate and the grooves 24 are separated from the feeding port 25, the solid part of the material distributing wheel 23 will seal the feeding port 25, effectively preventing the excessive falling of peanut granules. This cycle mechanism of feeding, closing, and feeding not only realizes the precise control of indirect quantitative feeding but also avoids the problems of sudden pressure increase or no-load operation of the pressing mechanism 14 caused by uneven feeding through a stable material supply, greatly improving the stability and pressing efficiency of the device operation and laying a solid mechanical transmission foundation for the subsequent efficient extraction of peanut oil.

[0025] Refer to Figure 2 、 Figure 3 、Figure 7 and Figure 8 As shown in Figure 8 , the speed regulating assembly includes a hollow box 31 fixedly connected to the side of the blanking hopper 15. A driving rod 32 is movably inserted through the side of the hollow box 31. A differential wheel 33 is fixedly sleeved on the outer surface of the driving rod 32. The differential wheel 33 is designed with a frustum structure, and the side line of the differential wheel 33 and the axis line of the transmission rod 26 are on the same horizontal line. One end of the driving rod 32 extending out of the hollow box 31 is connected to the belt transmission mechanism 16. One end of the transmission rod 26 extending out of the blanking hopper 15 extends into the hollow box 31 and is rotatably connected to the inner wall of the hollow box 31. A transmission wheel 34 is movably sleeved on the outer surface of the transmission rod 26. The outer surface of the transmission wheel 34 is meshed and connected with the differential wheel 33. A lead screw 35 is movably inserted through the side of the hollow box 31. A slide seat 36 is threadedly sleeved on the outer surface of the lead screw 35. A collar 37 is fixedly connected to the outer surface of the slide seat 36. The collar 37 is sleeved on the outer surface of the transmission rod 26 and they do not contact each other. The collar 37 is rotatably connected to the side of the transmission wheel 34. One end of the lead screw 35 passing through the hollow box 31 is fixedly connected to a rocker 38. The driving wheel is fixedly sleeved on the outer surface of the driving rod 13. The driven wheel is fixedly connected to one end of the driving rod 32 extending out of the hollow box.

[0026] When the staff rotates the rocker 38, the lead screw 35 generates a rotational motion under its drive. Through the thread engagement relationship, the slide seat 36 is driven to make a precise linear motion along the axis of the lead screw 35. The linear displacement of the slide seat 36 will be transmitted to the sliding sleeve, pushing the transmission wheel 34 to slide axially on the transmission rod 26. The differential wheel 33 is designed with a frustum shape, and its conical surface radius decreases linearly from the large end to the small end. When the meshing position of the transmission wheel 34 on the conical surface of the differential wheel 33 is close to the large end, due to the larger contact radius, the circumferential linear velocity obtained per unit time is faster, resulting in an increase in the rotational speed of the transmission wheel 34. When the meshing position moves towards the small end, the contact radius decreases, the linear velocity decreases, and the rotational speed of the transmission wheel 34 slows down accordingly. This transmission principle based on the change of the conical surface radius enables the change of the position of the transmission wheel 34 to be directly related to the speed regulation. By continuously rotating the rocker 38, stepless speed change of the transmission rod 26 and the central rod 21 can be achieved. This speed regulation mechanism can not only flexibly adjust the speed according to the pressing requirements of materials of different sizes, but also avoid the speed fluctuation problem of traditional speed regulation methods, significantly improving the adaptability and practical value of the device to different working conditions.

[0027] Refer to Figures 4 to 6As shown in the figure, the pushing component includes a turntable 41 fixedly sleeved on the outer surface of the central rod 21. The turntable 41 is arranged on the upper surface of the hollow box 31. A chute 47 is provided on the upper surface of the turntable 41. The chute 47 is designed with an eccentric wheel. A pull rod 46 is connected in the chute 47 in a limited sliding manner. One end of the pull rod 46 away from the turntable 41 is fixedly connected with a cross bar 44. A push plate 45 is fixedly connected to the side of the cross bar 44. The push plate 45 is designed with an arc-shaped plate structure. An annular track 42 is fixedly connected to the outer surface of the hollow cylinder 22. A connecting rod 43 is connected in the annular track 42 in a limited sliding manner. One end of the connecting rod 43 away from the annular track 42 is hinged to the cross bar 44. The lower parts of both ends of the cross bar 44 are limited to slide inside the annular track 42 through the connecting rod 43, which has the effect of limiting the cross bar 44 and the push plate 45, and ensures the stability of the movement track of the push plate 45.

[0028] When the central rod 21 rotates, it drives the turntable 41 to rotate synchronously through key connection. The pin shaft at the edge of the turntable 41 is embedded in the chute 47. As the turntable 41 makes a circular motion, the pin shaft slides in the eccentric wheel-shaped chute 47. Due to the eccentricity between the center of the chute 47 and the rotation center of the turntable 41, the pin shaft drives the pull rod 46 to make a periodic reciprocating motion in the chute 47, converting the continuous rotation of the turntable 41 into the linear reciprocating motion of the pull rod 46. When the pull rod 46 moves forward, it pushes the cross bar 44 to drive the push plate 45 to translate towards the feeding port 25. The arc surface design at the front end of the push plate 45 can smoothly push the peanut particles accumulated near the feeding port 25 to the entrance of the hollow cylinder 22. When the pull rod 46 returns backward, the outward-expanded arc surface structure on the back of the push plate 45 will deflect the peanut particles at the rear to both sides, avoiding material accumulation and blockage. During the movement process, the eccentricity of the eccentric wheel ring determines the stroke of the push plate 45, and the rotation speed of the turntable 41 directly affects the reciprocating frequency of the push plate 45. The cooperation of the two enables the push plate 45 to complete the cyclic actions of quantitative pushing and material sorting within a unit time, not only enhancing the continuity of feeding, but also realizing the orderly sorting of materials through the two-way function of the push plate 45, effectively improving the blanking stability and quantitative control accuracy of the feeding unit.

[0029] Working principle: The user pours the prepared oil-pressing peanut particles into the feeding hopper 15, and then turns on the driving mechanism 12. Driven by the driving rod 13, the pressing mechanism 14 operates. The peanut particles in the feeding hopper 15 will continuously enter the end of the pressing mechanism 14. After being screw-extruded by the pressing mechanism 14, the oil will flow out and be collected, and the residue will be discharged at the end and can be used as nutrients. During the rotation of the driving rod, it will drive the speed-regulating component to operate through the belt transmission mechanism 16. After being speed-changed by the speed-regulating component, it drives the feeding unit to operate. With the assistance of the pushing component, the purpose of indirectly and evenly blanking is achieved, avoiding the situation of too much or too little material that may occur during continuous blanking, and realizing the effect of controllable blanking rate; Specifically, the driving rod 13 drives the rotation of the driving rod 32 by means of a belt transmission mechanism 16. As the differential wheel 33 rotates with the driving rod 32, it drives the rotation of the transmission and the transmission rod 26. The transmission rod 26 transmits the power into the hopper 15 and drives the synchronous rotation of the central rod 21 by driving the rotation of the second bevel gear 28 through the first bevel gear 27. During the rotation of the central rod 21, it drives the rotation of the distribution wheel 23 in the hollow cylinder 22. Since grooves 24 are symmetrically arranged on both sides of the distribution wheel 23, when the groove 24 on the outer surface of the distribution wheel 23 rotates to the position where it intersects with the feed inlet 25, the peanut particles stored in the hopper 15 will enter the groove 24 and fall into the pressing mechanism 14 through the hole at the lower part of the hopper 15, realizing the pressing operation. Since the size of the groove 24 is fixed, the number of peanut particles entering the hollow cylinder 22 each time is controlled within a corresponding range. And when the groove 24 on the outer surface of the distribution wheel 23 is separated from the feed inlet 25, the distribution wheel 23 closes the feed inlet 25. Running continuously in this way realizes the effect of indirect quantitative feeding, ensures the uniformity of the pressing operation of the pressing mechanism 14, avoids the situation of excessive pressure or no-load, and improves the stability of the device operation. In addition, during the rotation of the central rod 21, it also drives the synchronous rotation of the turntable 41. During the rotation of the turntable 41, it drives the pull rod 46 to slide along the chute 47. Since the chute 47 is designed as an eccentric wheel ring, the pull rod 46 will perform a linear reciprocating motion during the sliding process, achieving the effect of converting rotation into a linear reciprocating motion. During the movement of the pull rod 46, it will pull the cross bar 44 and the push plate 45 to move synchronously. When the push plate 45 moves towards the feed inlet 25, it will push the peanut particles into the hollow cylinder 22. When the push plate 45 moves away from the feed inlet 25, it will deflect the peanut particles at the rear to both sides, facilitating the next pushing and feeding. In this way, it plays an auxiliary feeding effect, improves the stability of the feeding of the feeding unit and the effect of quantitative feeding. Since the lower parts of both ends of the cross bar 44 are limited and slide inside the annular track 42 through the connecting rod 43, it plays a role in limiting the cross bar 44 and the push plate 45, ensuring the stability of the movement track of the push plate 45; For the oil extraction of peanuts with different particle sizes, the required pressing conditions are different. It is necessary to control the feeding amount per unit time to ensure the smooth progress of the pressing. Therefore, it is necessary to adjust the feeding rate of the device, that is, to adjust the rotation speed of the center rod 21. When the machine is stopped, the staff rotates the rocker 38 to drive the screw rod 35 to rotate through the rocker 38. During the rotation of the screw rod 35, the slide 36 is driven to make a linear motion along the screw rod 35, and then the sleeve is driven to push the transmission wheel 34 to make a linear motion along the axis of the transmission rod 26. The position change of the transmission wheel 34 will cause a different meshing position with the differential wheel 33. Since the differential wheel 33 is a truncated cone structure, the closer to the larger end, the faster the rotation speed of the transmission wheel 34 will be, and the closer to the smaller end, the slower the rotation speed of the transmission wheel 34 will be. In this way, when the position of the transmission wheel 34 changes, its rotation speed will change accordingly, thereby driving the rotation speeds of the transmission rod 26 and the center rod 21 to change synchronously, thereby achieving the effect of adjusting the rotation speed and improving the practicality of the device. It should be noted that, in the process of the center rod 21 driving the dividing wheel 23 to rotate, the overlap of the groove 24 on the outer surface of the dividing wheel 23 and the feed port 25 is a dynamic process, which is a process from contact to overlap and then to offset. During this dynamic operation, the push plate 45 also operates synchronously. When the push plate 45 runs closest to the feed port 25, the groove 24 overlaps with the feed port 25, so as to ensure that the auxiliary pushing effect is optimal.

[0030] The technical scope of the present invention is not limited to the contents in the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
