[0021] As Figures 1-3 shown, a screw pressing device for vegetable oil production includes an inner cylinder 3, an outer cylinder 1, a support frame 11, a cylinder 19, a motor 10, a screw blade 12 and a collection box 15. The collection box 15 is arranged at the bottom of the outer cylinder 1 and an oil outlet 14 is arranged at the bottom of the collection box. The outer cylinder 1 and the collection box 15 are arranged on the support frame 11. The inner cylinder 3 is arranged inside the outer cylinder 1 and is coaxial with the outer cylinder 1. A cavity 13 is arranged inside the inner cylinder 3 and one end is open. The end of the inner cylinder 3 far away from the opening is connected to the output end of the motor 10. The motor 10 is fixedly arranged on the support frame 11 and the output end is rotatably connected to the outer cylinder 1 through a bearing 9. The screw blade 12 is arranged on the outer side wall of the inner cylinder 3. A plurality of first filter holes 4 are uniformly arranged on the inner cylinder 3. An inlet 8 is arranged on the upper part of the outer side wall of the outer cylinder 1 near the motor 10. One end of the outer cylinder 1 far away from the motor 10 is designed to be open. A fixing plate 20 is arranged on the support frame corresponding to the open side of the outer cylinder 1. The cylinder 19 is fixedly arranged on the fixing plate 20 and is coaxial with the outer cylinder 1. A baffle 17 matching the inner diameter of the outer cylinder 1 is arranged at the telescopic end of the cylinder 19. An oil discharge pipe 18 is arranged on the baffle 17, and the movement of the baffle 17 can make the oil discharge pipe 18 insert into the cavity 13 of the inner cylinder 3. A plurality of second filter holes 6 are uniformly arranged on the outer cylinder 1. A first diversion groove 5 is arranged on the outer side wall of the inner cylinder 3 corresponding to the position of the first filter holes 4 and along the circumferential direction of the inner cylinder 3. A second diversion groove 7 is arranged on the outer side wall of the outer cylinder 1 corresponding to the position between the second filter holes 6 and along the circumferential direction of the outer cylinder 1. The cavity 13 of the inner cylinder 3 is designed to be "conical", and the inner diameter of the side of the inner cylinder 3 near the opening is larger than the inner diameter of the side far away from the opening. The outer part of the outer cylinder 1 is wrapped with a protective cover 2. A groove 16 matching the inner cylinder 3 is arranged on the side wall of the baffle 17.

[0022] The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, which are as follows:

[0023] According to the specification appendix Figures 1-3It can be seen that when the utility model is working, the cylinder 19 is started so that its telescopic end drives the baffle 17 to block the open end of the outer cylinder 1 and the open end of the inner cylinder 3. The side wall of the baffle 17 and the end face of the inner cylinder 3 are slidably sealed. The existing technology can be used, or the side wall of the baffle 17 is close to the end face of the inner cylinder 3, so that the grease is difficult to flow out from here. At this time, the oil discharge pipe 18 is inserted into the inner cylinder 3. The raw material is put into the feed port 8 of the outer cylinder 1, and the motor 10 is started. The output end of the motor 10 rotates to drive the inner cylinder 3 and the spiral blade 12 to rotate. The spiral blade 12 cooperates with the outer cylinder 1, the inner cylinder 3 and the baffle 17 to gradually squeeze the raw material entering. The outer cylinder 1 is provided with a second filter hole 6, and the inner cylinder 3 is provided with a first filter hole 4, which greatly increases the contact area with the raw material. When squeezing, the area of ​​grease discharge is large, and it is discharged from the first filter hole 4 and the second filter hole 6 respectively, and the oil collection is faster and more efficient. The grease in the inner tube 3 enters the cavity 13 and can be discharged from the oil drain pipe 18 on the baffle 17. The outside of the oil drain pipe 18 can prevent easy reception and can also be connected to the pump body for extraction and collection. The grease discharged from the outer tube 1 is collected by the collection box 15. A valve is designed on the oil outlet 14 at the bottom of the collection box 15 to facilitate discharge.

[0024] Among them, the outer wall of the inner cylinder 3 corresponds to the position of the first filter hole 4 and a first guide groove 5 is opened along the circumference of the inner cylinder 3. During extrusion, the grease of the raw material in contact with the outer wall of the inner cylinder 3 can flow into the cavity 13 of the inner cylinder 3 along the first guide groove 5 through the first filter hole 4, making it easier to collect the grease.

[0025] Among them, the outer wall of the outer cylinder 1 corresponds to the position between the second filter holes 6 and a second guide groove 7 is opened along the circumference of the outer cylinder 1. Since the outer cylinder 1 is fixed, the top grease is squeezed out and flows along the side wall to easily enter other second filter holes 6 again, and when the internal extrusion pressure is unstable, the grease will easily return to the second filter hole 6, affecting the discharge efficiency. Therefore, after the second guide groove 7 is set, the discharged grease will flow along the specified path after entering the second guide groove 7 and will not return to the position of the second filter hole 6, thereby improving the discharge and collection efficiency.

[0026] Among them, the cavity 13 of the inner cylinder 3 is designed to be "conical", and the inner diameter of the opening side of the inner cylinder 3 is larger than the inner diameter of the side away from the opening. The grease entering the inner cylinder 3 will flow along the cavity 13 of the inner cylinder 3 to the side of the oil drain pipe 18 for easy collection.

[0027] The outer cylinder 1 is wrapped with a protective cover 2 to ensure a clean and tidy pressing working environment and prevent dust from contaminating the grease.

[0028] Among them, the side wall of the baffle 17 is provided with a groove 16 matching the inner cylinder 3. During extrusion, the baffle 17 moves toward the inner cylinder 3 so that the groove 16 is buckled into the open end of the inner cylinder 3. Here, the groove 16 only serves to reduce the gap between the baffle 17 and the inner cylinder 3 and to limit the position, and will not affect the rotation of the inner cylinder 3.

[0029] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
