[0003] An existing utility model patent with application number CN202321366233.4 discloses a pressing device for edible oil production, including a housing. A connecting pipe is fixedly connected to the left side of the housing, a housing door is hinged to the front of the housing, an oil outlet pipe is fixedly connected to the left side of the housing, and a feeding assembly is provided on the left side of the housing. In this pressing device for edible oil production, when the raw materials for edible oil production enter the housing… the raw materials within the fixed frame are fully squeezed to increase the oil yield. The pressed edible oil is filtered through a filter screen and finally discharged through the oil outlet pipe.

[0004] Despite the advantages mentioned above, the material tends to adhere to the filter screen during the pressing process, requiring frequent maintenance and cleaning. Maintenance and cleaning necessitate opening the housing door to access the filter screen, which is difficult to remove, significantly increasing the difficulty and complexity of maintenance.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-4A pressing device for edible oil production includes a base 1. Four rectangularly distributed support columns 7 are fixedly connected to the lower end of the base 1 to form the base 1. Rubber pads are fixedly connected to the lower ends of the support columns 7 to improve their wear resistance. The base 1 has a hollow groove that connects front and back. A horizontally arranged movable disc 2 is rotatably connected to the bottom of the hollow groove to rotate and switch the positions of two pressing grooves. An inclined feeding pipe 8 is provided at the upper end of the movable disc 2, near its left edge, to facilitate the connection of external feeding or crushing equipment to transport materials into the pressing grooves. One upwardly inclined end of the feeding pipe 8 penetrates the base 1, and the feeding pipe 8 is fixedly connected to the base 1. A horizontally arranged locking screw 3 is inserted into the outer wall of the base 1 to prevent the movable disc 2 from loosening or rotating. The locking screw 3 is threadedly connected to the base 1. The movable disc 2 has corresponding slots on both its left and right sides, with one end of the locking screw 3 penetrating the base 1 and extending into the slot.

[0025] In this embodiment, a vertically arranged connecting column 9 is fixedly connected to the upper end of the movable disk 3 near the center position to drive the movable disk 3 to rotate. A servo motor 12 is fixedly connected to the upper end of the base 1 to drive the connecting column 9 to rotate. The upper end of the connecting column 9 passes through the base 1 and is fixedly connected to the end of the output shaft of the servo motor 12. The connecting column 9 and the base 1 are rotatably connected. Both ends of the connecting column 9 are rotatably sleeved with a first connecting ring 13 to improve the stability of the connecting column 9. The opposite sides of the two first connecting rings 13 are fixedly connected to the inner top of the hollow groove and the upper end of the movable disk 2, respectively. A vertically arranged limiting column 10 is fixedly connected to the lower end of the movable disk 2 near the center position to prevent the movable disk 2 from swaying left and right. The inner bottom of the hollow groove is provided with a connecting groove corresponding to the limiting column 10. The lower end of the limiting column 10 is rotatably connected to the inner bottom of the connecting groove.

[0026] In this embodiment, the upper end of the movable disc 2 is provided with two symmetrically arranged pressing grooves, which are located on both sides of the connecting column 9. The upper end of the filter plate 4 and near the edge is provided with a receiving groove. A semi-circular pull ring 5 is fixedly connected to the inner bottom of the receiving groove for easy removal of the filter plate 4 by the user. The filter plate 4 is slidably placed in the inner bottom of the pressing groove for filtering the pressed oil. The inner bottom of the pressing groove is provided with a second opening near the center for allowing the pressed oil to flow into the groove 6. The inner bottom of the pressing groove is provided with multiple guide grooves that communicate with the second opening in a ring shape for allowing the pressed oil to flow into the second opening. The inner bottom of the hollow groove is provided with a groove 6 that communicates with the second opening for the flow of pressed oil. The groove 6 is ring-shaped, and the inner bottom of the groove 6 is provided with a first opening for the outflow of pressed oil.

[0027] In this embodiment, a pressure plate 11 is slidably connected to the inner wall of one of the pressing troughs for pressing down materials. A vertically arranged guide rod 16 is fixedly connected to the upper end of the pressure plate 11 for guiding the pressure plate 11 to rise and fall. The upper end of the guide rod 16 slides through the base 1. The upper end of the pressure plate 11 passes through the pressing trough and is fixedly connected to a vertically arranged electric push rod 14 for driving the pressure plate 11 to rise and fall. The upper end of the electric push rod 14 passes through the base 1, and the electric push rod 14 and the base 1 are fixedly connected. Two second connecting rings 15 are fixedly sleeved on the electric push rod 14 to improve the firmness of the electric push rod 14. The opposite sides of the two second connecting rings 15 are fixedly connected to the inner top of the hollow trough and the upper end of the pressure plate 11, respectively.

[0028] In this embodiment, when the operation begins, the material is first placed in the pressing trough below the pressing plate 11. Then, the electric push rod 14 is started to drive the pressing plate 11 to move downward into the pressing trough to press the material, so that the oil in the material is squeezed out. The pressed oil passes through the filter plate 4 and flows into the guide trough. Then it enters the groove 6 through the second opening and finally flows out from the first opening. The operator can collect the pressed oil at the first opening. During the pressing process, materials can be prepared in another pressing tank in advance. After the pressing is completed, the pressing plate 11 is raised by the electric push rod 14, then the locking screw 3 is unscrewed from the slot, and the servo motor 12 is started to make the connecting column 9 rotate. The connecting column 9 drives the movable plate 2 to rotate, thereby realizing the switching of the positions of the two pressing tanks. By using this method of alternating operation of the two pressing tanks, it is convenient to maintain and clean one of the pressing tanks. On the other hand, the normal pressing operation of the other pressing tank is not affected during the cleaning process. In addition, the user can easily remove the filter plate 4 from the pressing tank by holding the pull ring 5 on the filter plate 4, which further improves the convenience of maintenance and cleaning.

[0029] As mentioned above, servo motors and electric linear actuators are existing mature technologies, and their working principles and internal structures are known to those skilled in the art. This application only utilizes their functions and does not improve their internal structures; therefore, it will not be described in detail.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
