Background

The screw oil press is mainly used for oil presses for individual household processing. The product belongs to one of hydraulic full-automatic oil presses; when the oil press is operated, the treated oil enters the barrel from the hopper. The material blank is continuously pushed inwards by the rotation of the pressing screw to be pressed. Because the material blank is carried out in the barrel of the oil press in a moving state, under the condition of high pressure of the barrel, great frictional resistance is generated between the material blank and the pressing screw, between the material blank and the barrel, and thus, friction is generated between the material blank and the micro material to cause relative movement. On the other hand, the root circle diameter of the pressing screw is gradually increased, and the thread pitch is gradually reduced, so that when the pressing screw rotates, the screw thread can make the material blank be pushed forward and turned over outwards, and meanwhile, the material layer close to the surface of the pressing screw thread also rotates along with the pressing shaft.

A general oil press is mostly used for pressing oil from grains containing oil such as peanuts, sesames, beans and the like, so that the design of the oil press is designed for various grains; because the sizes, the grains and the oil contents of the grains are different, the oil outlet hole must be designed in a compromise way, so that the situation that the oil outlet is blocked by material residues can occur when the designed oil press presses the oil of different grains; blocked oil outlets are difficult to clean due to their small size, particularly for oil presses with multiple oil outlets; on the other hand, when different cereals are used for oil extraction in sequence, the influence of the material residue of the previous cereal on the oil extraction of the subsequent cereal is prevented, and the material residue of the previous cereal or the material residue at the oil outlet needs to be cleaned during the subsequent oil extraction.

In the invention, in the working process, after the material blank enters the press cylinder 3, the direction in which the material blank is driven to feed and the force by which the first spring 32 drives the first press cylinder 13, the second press cylinder 35 and the third press cylinder 36 to reset and close are different, namely the feeding of the material blank has the driving force for opening the press cylinder 3 along the axis, in order to prevent the press cylinder 3 from being opened, the invention designs the limit threaded ring 55, the adjacent press cylinders are connected by the threaded fit of the complete external threaded region formed by the plurality of limit threaded rings 55, the external threads on the areas of the press cylinder, which are provided with the first connecting notch 40 and the second connecting notch 48, and the matched arc plate 58, and the press cylinder 3 is prevented from being opened, in addition, the limit threaded ring 55 is limited by pressing the limit strip 38 in the pressing process, and the limit threaded ring 55 is prevented from deviating due to vibration, the limit of the pressing cylinder is lost.

The oil outlet 50 is relatively small, and the position of the oil outlet 50 is only convenient to look at and understand the working principle of the oil outlet 50 in the drawing; the general stock is difficult to fall into the oil outlet 50 to support the oil outlet 50, so the press cylinder 3 designed by the invention cannot support the press cylinder 3 because the stock falls into the oil outlet 50.

The specific diameter variation ratio of the mounting shaft 8 in the present invention is prior art and is only schematically shown in the figures.

The specific working process is as follows: when the squeezing machine designed by the invention is used, the motor 25 is controlled to work, when the motor 25 works, the sun gear 30 is driven to rotate through the output shaft, the sun gear 30 rotates to drive the three planet gears 26 to rotate, the three planet gears 26 rotate to drive the gear ring 29 to rotate, the gear ring 29 rotates to drive the output rotating shaft 27 to rotate, the output rotating shaft 27 rotates to drive the mounting shaft 8 to rotate, the mounting shaft 8 rotates to drive the squeezing spiral sheet 9 to rotate, then the material blank is poured into the squeezing cylinder 3 from the feeding hopper, and the material blank entering the squeezing cylinder 3 can be continuously pushed inwards under the action of the squeezing spiral sheet 9 to be squeezed.

When the use is finished or the blank is replaced, the screw rod 23 is rotated, so that the screw rod 23 drives the threaded sleeve 17 to slide on the upper side of the guide rail 18 under the matching action of the screw rod 23 and the threaded sleeve 17, the threaded sleeve 17 slides to drive the driving block 16 to slide, the driving block 16 can push the transmission block 14 to slide through the second spring 60 on the corresponding side, and in the process, one of the two second springs 60 is stretched, and the other one is compressed; the transmission block 14 slides to drive the second squeezing barrel 35 to slide towards the side far away from the power module 2; when the second barrel 35 is forced to slide towards the side far from the power module 2, the second barrel 35 will pull the corresponding first spring 32 through the upper sliding block 31 thereof, so that the first spring 32 will bring the corresponding third barrel 36 to slide towards the side far from the power module 2 through the sliding block 31 on the third barrel 36 adjacent thereto, and similarly, when the third barrel 36 close to the first barrel 13 moves, the third barrel 36 will bring the adjacent third barrel 36 to move through the corresponding sliding block 31 and the first spring 32, and then transfer in turn, and finally the third sliding block 36 close to the first barrel 13 will pull the first spring 32 installed between the first barrel 13 and the third barrel 36 through the corresponding sliding block 31, so that the stretching amount of the first spring 32 increases, in this state, a gap appears between the annular groove 39 and the annular plate 49 of the two adjacent barrels, a gap appears between the first connecting notch 40 and the area between two adjacent second notches, a gap appears between the second connecting notch 48 and the area between two adjacent first notches, the oil outlet 50 between the first oil leakage port 44 and the second oil leakage port 45 is enlarged, and a gap appears between the matching groove and the matching notch 59; in this state, the cleaning liquid can be added into the inner side of the oil squeezing cylinder from the outer side through the gap between the annular groove 39 and the annular plate 49 of the two adjacent oil squeezing cylinders, the gap between the first connecting notch 40 and the two adjacent second notches, and the gap between the second connecting notch 48 and the two adjacent first notches, so as to clean the inner side of the oil squeezing cylinder, and then the cleaning liquid is discharged through the oil outlet holes 50 of the first oil leakage port 44 and the second oil leakage port 45, the matching notch 59 and the matching groove, so that the cleaning is convenient, and the oil outlet hole 50 formed by the first oil leakage port 44 and the second oil leakage port 45 can be elongated, so that the cleaning liquid is not easily blocked.

After cleaning is finished, when the screw 23 is rotated to enable the threaded sleeve 17 to slide towards one side close to the power module 2, the threaded sleeve 17 slides to drive the driving block 16 to slide, the compression and extension amount of the two second springs 60 can be gradually restored in the sliding process of the driving block 16, after the first press barrel 13 is completely restored, the lengths of the two second springs 60 are restored to the initial state, at this time, the continuous movement of the driving block 16 enables the lengths of the two second springs 60 to be changed again, when an operator observes that the two second springs 60 are restored to the initial lengths and then start to be changed again, the press barrel 3 is also completely restored, at this time, the annular grooves 39 of the two adjacent press barrels are nested and matched with the annular plate 49, the first connecting notches 40 are nested and matched with the areas between the two adjacent second notches, and the second connecting notches 48 are nested and matched with the areas between the two adjacent first notches, the sealing plates are matched with the sealing grooves in a one-to-one correspondence manner; the first oil leakage ports 44 and the second oil leakage ports 45 are correspondingly matched to form two oil outlet holes 50, and the first connecting arc plate 10 and the second connecting arc plate 46 are correspondingly matched in an inner-outer nested mode.
