Description

Technical Field

[0001] The utility model relates to the technical field of oil presses, in particular to a crushing and feeding device for an oil press. Background Art

[0002] An oil press is a device that uses mechanical external force to activate oil molecules by increasing temperature and extrudes oil from oil materials. The feeding device is one of the components of the oil press equipment. It, together with the main components such as the pressing chamber, the screw assembly, the electric control box, the machine box, and the motor, constitutes the entire oil press. The function of the feeding device is to feed the processed oil materials from the hopper into the pressing chamber to ensure that the raw materials can be continuously supplied to the pressing chamber for pressing.

[0003] Currently, the commonly used oil presses on the market usually go through three times of pressing. A large-sized feeding hopper is arranged above the hopper of the oil press body, and a large amount of materials are buffered through this large-sized feeding hopper to ensure that the oil pressing can be carried out cyclically. When the second or third pressing is performed on the materials, after the cake is conveyed to the feeding hopper by the feeding mechanism, since the cake formed after pressing has a certain humidity, if the amount of cyclic pressing is large, the cakes are likely to stick together in the feeding hopper. Therefore, it is necessary to constantly stir manually to make them fall into the hopper. Since the feeding hopper is at a high place, it is necessary for workers to step on a high place to stir it, which not only has low work efficiency, but also increases the labor intensity and personal danger of the workers. Summary of the Utility Model

Detailed implementation manners

[0017] The following are specific embodiments of the present utility model, and the technical solutions of the present utility model are further described in conjunction with the accompanying drawings, but the present utility model is not limited to these embodiments.

[0018] As Figures 1-5 shown, the present utility model provides a crushing and feeding device for an oil press, including an oil press body 1, a feeding mechanism 3 is provided on one side of the oil press body 1, the feeding mechanism includes a base 4, a transfer cylinder 5 and a first screw feeder 6 are provided on the base 4, the discharge port end at the lower part of the transfer cylinder 5 is communicated with the feed port end of the first screw feeder 6 through a connecting frame 7, a turntable 8 is provided at the bottom inside the transfer cylinder 5, a feeding plate 9 is provided on the turntable 8, a driving mechanism 10 is provided at the bottom of the base 4, the driving mechanism 10 drives the turntable 8 and the first screw feeder 6 to work, a second screw feeder 11 is provided on one side of the base 4, the discharge port end of the second screw feeder 11 feeds materials into the transfer cylinder 5 through a first blanking hopper 12, and the discharge port end of the first screw feeder 6 feeds materials into the hopper 2 of the oil press body 1 through a second blanking hopper 13.

[0019] As Figures 1-3As shown, in this embodiment, the structure of the oil press body 1 is prior art, and its structure will not be elaborated in detail in this embodiment. The cake produced after the initial pressing by the oil press body 1 is conveyed into the transfer cylinder 5 along the first hopper 12 by the second screw feeder 11. At the same time, the turntable 8 rotates, driving the material distributing plate 9 to rotate. During the rotation of the material distributing plate 9, on the one hand, the cake in the transfer cylinder 5 and above the turntable 8 is broken up, and on the other hand, the broken cake is conveyed along the connecting frame 7 into the first screw feeder 6. The first screw feeder 6 conveys the broken cake along the second hopper 13 into the hopper of the oil press body 1 to form a cyclic pressing; in the prior art, the height of the hopper generally does not exceed 3m, and its continuous cyclic pressing amount does not exceed 60kg, otherwise the cake will agglomerate in the hopper, resulting in difficult feeding. However, the feeding device proposed in this embodiment can continuously and cyclically press 20kg - 200kg of materials. Compared with the prior art, the production volume is greatly increased; because the cake has a certain temperature, when in an open state and in a hopper with a wider upper part and a narrower lower part, the moisture is likely to be lost. The cylindrical structure of the transfer cylinder 5 can ensure less moisture loss of the cake. The cake in the transfer cylinder 5 will not be mixed during pressing, ensuring the oil yield. Compared with the hopper at a high position, it is simple and convenient to operate. Through the turntable 8 and the material distributing plate 9, the cake is broken up and fed to the feeding port end of the first screw feeder 6. Even if the cyclic pressing amount is increased, there is no need to agitate the cake, which saves time and effort, reduces the labor intensity of the staff and personal danger.

[0020] The driving mechanism 10 includes a mounting seat 14, a driving motor 15, a driving pulley 16, a driven pulley set 17 and a driven pulley 18. The mounting seat 14, the driven pulley set 17 and the driven pulley 18 are all arranged at the bottom of the base 4. The driving motor 15 is installed on one side of the base 4 through a support frame 19. The output end of the driving motor 15 is connected to the driving pulley 16. The driven pulley set 17 is rotatably installed on the mounting seat 15 through a first rotating shaft 20. One end of the first rotating shaft 20 away from the mounting seat 14 passes through the bottom of the transfer cylinder 5 and is connected to the bottom of the turntable 8. The driven pulley 18 is rotatably installed on the mounting seat 14 through a second rotating shaft 21. One end of the second rotating shaft 21 away from the mounting seat 14 is connected to the end of the screw shaft of the first screw feeder 6. The driving pulley 16 is connected to the driven pulley set 17, and the driven pulley set 17 is connected to the driven pulley 18 through a belt 22.

[0021] As Figure 1 and Figure 4As shown, the driven pulley set 17 includes two pulleys with different diameters. The pulley with the larger diameter in the driven pulley set 17 is connected to the driving pulley 16 by a belt 22, and the pulley with the smaller diameter in the driven pulley set 17 is connected to the driven pulley 18 by a belt 22. During specific operation, the driving motor 15 drives the driving pulley 16 to rotate. Under the action of the belt 22, the driven pulley set 17 rotates, the driven pulley set 17 drives the turntable 8 to rotate, and at the same time the driven pulley set 17 drives the driven pulley 18 to rotate. The driven pulley 18 drives the first screw feeder 6 to work, and the second screw feeder 11 is driven by a motor arranged at its lower part.

[0022] The first hopper 12 has a "human" - shaped double discharge port structure. An outlet adjustment mechanism is provided in the middle of the first hopper 12. The outlet adjustment mechanism includes an electric telescopic rod 23, a rotating shaft 24 and a baffle 25. The electric telescopic rod 23 is arranged on the outer wall of the first hopper 12. The rotating shaft 24 is rotatably installed in the first hopper 12. The baffle 25 is arranged on the rotating shaft 24. One end of the rotating shaft 24 passes through the first hopper 12 and is connected to a connecting rod 26. The other end of the connecting rod 26 is hinged to the output shaft of the electric telescopic rod 23.

[0023] As Figure 1 and Figure 5 shown, the first hopper 12 can discharge materials in two directions. One discharge port of the first hopper 12 is inside the transfer cylinder 5, which is convenient for feeding materials into the transfer cylinder 5. When the material is pressed three times, the finally produced cake is discharged from the other discharge port of the first hopper 12. In this embodiment, when the electric telescopic rod 23 is in a contracted state, the discharge port on one side of the transfer cylinder 5 is in an open state, and vice versa. Specifically, under the action of the connecting rod 26, the electric telescopic rod 23 drives the rotating shaft 24 to rotate, and the rotating shaft 24 drives the baffle 25 to rotate until the baffle 25 contacts the inner wall of the first hopper 12.

[0024] A horizontally placed third screw feeder 27 is provided on one side of the second screw feeder 11. The feeding end of the third screw feeder 27 is communicated with the discharging end 28 of the oil press body 1, and the discharging port end of the third screw feeder 27 is communicated with the feeding port end of the second screw feeder 11.

[0025] As Figure 1 shown, the third screw feeder 27 of the present utility model is driven by the power mechanism of the oil press body 1. The power mechanism of the oil press body 1 has a similar driving principle to the driving mechanism 10 of the present utility model, so it will not be elaborated in this embodiment and the drawings. The present utility model drives the third screw feeder 27 to feed materials into the second screw feeder 11 through the power mechanism of the oil press body 1.

[0026] Principle of use: During operation, first control the electric telescopic rod 23 to be in a contracted state, so that the discharge port of the first hopper 12 close to one side of the transfer cylinder 5 is in an open state. Then, put the processed materials into the hopper 2 through the material feeding machine, and conduct preliminary pressing on them through the oil press body 1. The cake formed after preliminary pressing enters the third screw feeder 27 along the discharge end 28 of the oil press body 1, and enters the second screw feeder 11 along the third screw feeder 27. Under the action of the second screw feeder 11, it is conveyed to the transfer cylinder 5. Start the drive motor 15, and the drive motor 15 drives the turntable 8 and the first screw feeder 6 to work. Under the action of the turntable 8 and the material deflecting plate 9, the cake on the turntable 8 is broken and deflected into the connecting frame 7, and enters the first screw feeder 6 along the connecting frame 7. The broken cake is conveyed into the hopper 2 for secondary pressing. Similarly, tertiary pressing is carried out. After the final pressing is completed, control the electric telescopic rod 23 to extend, and the cake residue will be discharged from the other outlet of the first hopper 12 of the second screw feeder 11, which is convenient for collection.
