It should be understood that in all these drawings, the same or similar reference numerals indicate the same or similar parts and features. Each drawing only schematically shows the concept and principle of the implementation mode of the present disclosure, and does not necessarily show the specific dimensions and their ratios of each implementation mode of the present disclosure. The relevant details or structures of the implementation mode of the present disclosure may be illustrated in an exaggerated manner in a specific part of a specific drawing.

[0047] Embodiment 1

[0048] Refer to Figure 1 and Figure 3 As shown in [relevant figures], an automatic slag - discharging sesame oil press includes an equipment frame, a screw cage 1, a screw rod 2, a motor 6, a feed hopper 7, a slag discharge hopper 8, and an oil collecting hopper 9. The screw cage 1, the motor 6, and the slag discharge hopper 8 are all installed on the equipment frame. The screw rod 2 is rotatably connected inside the screw cage 1, and the output part of the motor 6 is linked with the screw rod 2.

[0049] The screw cage 1 includes a plurality of cage bodies 101. The plurality of cage bodies 101 are stacked to form the screw cage 1, and oil can seep between adjacent cage bodies 101. The two ends of the screw cage 1 are respectively rotatably connected with a first end seat 11 and a second end seat 12. The first end seat 11 and the second end seat 12 are fixed on the equipment frame. The two ends of the screw rod 2 are respectively rotatably connected with the first end seat 11 and the second end seat 12 through slewing bearings. And a pull rod 13 is fixed between the first end seat 11 and the second end seat 12, that is, the two ends of the pull rod 13 are respectively fixedly connected with the first end seat 11 and the second end seat 12, aiming to clamp the screw cage 1. And the screw cage 1 is connected with the first end seat 11 and the second end seat 12 through slewing bearings, which will not affect the rotation of the screw cage 1. The screw rod 2 is composed of a smooth rod and spiral blades spirally wound on the surface of the smooth rod, and the pitch of the spiral blades gradually decreases along the axis direction of the smooth rod. Specifically, the pitch of the spiral blades is smaller in the direction farther away from the feed hopper 7.

[0050] Specifically, referring to Figure 7 and Figure 8 As shown, a connecting pile 101a is fixed on the side of the cage body 101, and a connecting groove 101b for connecting the connecting pile 101a is opened on the side of the cage body 101. Multiple cage bodies 101 are connected by the cooperation of the connecting pile 101a and the connecting groove 101b; the purpose is that multiple cage bodies 101 can rotate synchronously;

[0051] More specifically, referring to Figure 3 and Figure 5 As shown, the slag discharge hopper 8 is fixed on the second end seat 12. The slag discharge hopper 8 is in an "L" shape, and the inside of the slag discharge hopper 8 is hollow. A slag discharge hole 121 is opened through the outer surface of the second end seat 12. The inner cavity of the pressing cage 1 is communicated with the inner cavity of the slag discharge hopper 8 through the slag discharge hole 121. The oil collecting hopper 9 is fixed on the upper surface of the slag discharge hopper 8 and is located below the pressing cage 1. The feeding hopper 7 is fixed on the first end seat 11;

[0052] Exemplarily, for example, when extracting sesame oil, sesame enters the pressing cage 1 from the feeding hopper 7. The screw rod 2 is rotated by the motor 6, so that the spiral blades on the surface of the screw rod 2 push the sesame to be extruded along the axis direction of the screw rod 2, and by using the change of the pitch on the surface of the screw rod 2, the extrusion force of the sesame becomes greater and greater, so as to press out the oil liquid from the sesame. The sesame oil seeps out from the gaps between adjacent cage bodies and converges on the oil collecting hopper 9.

[0053] Furthermore, referring to Figure 2 and Figure 5 As shown, a retaining ring 21 is fixed at the end of the screw rod 2. The purpose is to form a certain block for the material to prevent the material from entering the gap between the screw rod 2 and the first end seat 11 or the second end seat 12.

[0054] Even further, referring to Figure 2 , Figure 3 and Figure 6 As shown, a reverse slag removal pipe 3 is provided on the pressing cage 1. The reverse slag removal pipe 3 is used to blow air into the pressing cage 1 to control the temperature in the pressing cage 1 and reverse clean the residue. Specifically, spray nozzles 31 are uniformly fixed on the outer surface of the reverse slag removal pipe 3. The spray nozzles 31 are used to blow air between adjacent cage bodies. A connecting frame 32 is fixed on the outer surface of the reverse slag removal pipe 3, and the reverse slag removal pipe 3 is fixedly connected to the pull rod 13 through the connecting frame 32; an air supply pipe 4 is fixed on the first end seat 11. The air supply pipe 4 is used to provide air source for the reverse slag removal pipe 3; a piston rod 41 is slidably connected inside the air supply pipe 4. The piston rod 41 is used to generate high-pressure gas for the reverse slag removal pipe 3 by piston movement inside the air supply pipe 4. A one-way valve is fixed on the outer surface of the air supply pipe 4, and the flow direction of the one-way valve is from outside to inside the air supply pipe 4; Exemplarily, by making the piston rod 41 do piston movement inside the air supply pipe 4, the external gas can be pumped into the air supply pipe 4 through the one-way valve and then pushed into the reverse slag removal pipe 3;

[0055] It is worth mentioning that in this embodiment, the structure of the air supply pipe 4 and the piston rod 41 can also be replaced by an embolism pump.

[0056] Specifically, referring to Figure 6 As shown, a connecting rod 42 is hinged to one end of the piston rod 41 away from the air supply pipe 4. The other end of the connecting rod 42 is hinged to a cam 43. The outer surface of the cam 43 is rotatably connected to a support frame 47, and the support frame 47 is fixedly connected to the first end seat 11. The outer surface of the support frame 47 is rotatably connected to a first transmission shaft 44. One end of the first transmission shaft 44 is fixed with a pulley 441. A synchronous belt 442 is sleeved on the outer surface of the pulley 441. The other end of the synchronous belt 442 is linked with the cam 43. That is, a pulley 441 is also fixed at the bottom of the cam 43. The two ends of the synchronous belt 442 are respectively sleeved on the two pulleys 441. The other end of the first transmission shaft 44 is fixed with a transmission bevel gear 45. A driving bevel gear 46 is sleeved and fixed on the outer surface of the screw rod 2. And the transmission bevel gear 45 meshes with the driving bevel gear 46. Exemplarily, when the screw rod 2 rotates, it can drive the transmission bevel gear 45 to rotate through the driving bevel gear 46. The transmission bevel gear 45 drives the pulley 441 to rotate through the first transmission shaft 44. The driving belt drives another pulley 441 to rotate through the synchronous belt 442, and then drives the cam 43 to rotate. The cam 43 drives the piston rod 41 to perform a piston motion in the air supply pipe 4 through the connecting rod 42.

[0057] The purpose is that as long as the screw rod 2 works, there will be a continuous air source in the reverse slag removal pipe 3 to perform reverse slag removal on the pressing cage 1, that is, to blow the residues in the surface gaps of the pressing cage 1 back into the pressing cage 1, without the need to additionally increase an air pump, saving costs.

[0058] Furthermore, referring to Figure 3 、 Figure 4 、and Figure 7 As shown, a motor 6 is fixed on the outer surface of the slag discharge hopper 8. The output end of the motor 6 is fixed with a driving gear 61. The end of the screw rod 2 is fixed with a first transmission gear 62. And the driving gear 61 meshes with the first transmission gear 62. The first transmission gear 62 meshes with a driven gear 63. And the driven gear 63 is rotatably connected to the slag discharge hopper 8. A reduction gear 631 is coaxially fixedly connected to the outer surface of the driven gear 63. The reduction gear 631 meshes with a second transmission gear 64. The reduction gear 631 is a gear with missing teeth. The purpose is to intermittently drive the second transmission gear 64 to avoid the second transmission gear 64 rotating too fast.

[0059] The axis of the second transmission gear 64 is fixed with a second transmission shaft 641. The second transmission shaft 641 is rotatably connected to the slag discharge hopper 8. One end of the second transmission shaft 641 away from the second transmission gear 64 is fixed with a driving gear 642. Tooth blocks 101c are evenly fixed on the outer surface of the pressing cage 1. The driving gear 642 meshes with the tooth blocks 101c. The purpose is that while the screw rod 2 rotates, the pressing cage 1 can also rotate. On the one hand, it can switch positions to remove slag for the reverse slag removal pipe 3. On the other hand, the extrusion direction of the material in the pressing cage 1 is changed, that is, in addition to the extrusion force along the axis of the screw rod 2, there is also a shearing force in the rotational direction with the axis as the center. It is worth mentioning that to achieve the shearing force, part of the inner wall of the pressing cage 1 needs to have protrusions to form a shearing force with the screw rod 2, accelerating the oil extraction efficiency of sesame oil.

[0060] Embodiment 2

[0061] Refer to Figure 9 As shown, an automatic slag-discharging sesame oil press, on the basis of Embodiment 1, further includes a thermocouple 5 and a control electric box. A controller is arranged in the control electric box. The controller includes an acquisition module, a processing module, a temperature acquisition module, and a temperature recognition module. Among them, each module is connected by wire and / or wirelessly.

[0062] The thermocouple 5 is fixed on the air supply pipe 4 for adjusting the temperature in the air supply pipe 4, that is, changing the temperature of the gas entering the air supply pipe 4. The specific heat exchange structure is a known public technology and will not be elaborated too much here.

[0063] The acquisition module is used to acquire the oil liquid image. In this embodiment, the acquisition module can use a high-definition camera. And the high-definition camera acquires the oil liquid image under the condition of a fixed camera position and a fixed light source. Measures to avoid external ambient light are taken by those skilled in the art according to the actual situation on site. For example, the high-definition camera is installed on the oil collection hopper 9 in this embodiment, and measures such as arranging light-shielding plates around are taken to ensure acquisition under the condition of a fixed camera position and a fixed light source. Other measures are not specifically limited here.

[0064] The processing module is used to frame the oil liquid image to obtain the latest set of frame images, and acquire the real-time color value of the latest set of frame images. The specific method is to obtain the color values of n pixels in the real-time frame image. n is an integer greater than 1. The color values of n pixels establish an analysis set, and calculate the average value of the analysis set as the real-time color value, and calculate the average value of the analysis set as the real-time color value. The purpose is to improve the credibility of the real-time color value and avoid inaccurate values caused by the influence of local environmental problems or other problems on the image.

[0065] The temperature acquisition module is used to acquire the real-time temperature value inside the pressing cage 1. In this embodiment, the temperature acquisition module is a thermometer. The temperature acquisition module is arranged in the second end seat 12 to directly monitor the internal temperature of the pressing cage 1.

[0066] A temperature recognition module is configured to input real-time color values and real-time temperature values into a trained temperature recognition model, and output a target temperature value, which is used as an adjustment parameter for the thermocouple 5;

[0067] The temperature recognition module trains the temperature recognition model in the following way:

[0068] Pre-collect k sets of historical temperature adjustment data, where k is an integer greater than 1. The historical temperature adjustment data includes historical feature data and the target temperature value corresponding to the historical feature data;

[0069] Convert the historical feature data and the target temperature value corresponding to the historical feature data into a set of feature vectors;

[0070] Use each set of feature vectors as the input of a machine learning model. The machine learning model outputs the predicted target temperature value for each set of feature vectors, and takes minimizing the sum of the prediction accuracies of all target temperature values as the training objective; train the machine learning model until the sum of the prediction accuracies reaches convergence and then stop training. The trained machine learning model is used as a compensation recognition model.

[0071] Further, pre-collecting k sets of historical temperature adjustment data, such as pre-collecting k sets of historical temperature adjustment data in an experimental environment;

[0072] The historical temperature adjustment data includes historical feature data and the target temperature value corresponding to the historical feature data. The historical feature data includes the historical temperature value in the pressing cage 1 and the historical color value of the oil. That is, in the experimental environment, simulate multiple pressing oil scenarios with the same historical feature data, use different target temperature values as experimental parameters to conduct experiments on this pressing oil scenario, and finally obtain multiple sets of oil samples. Then, let those skilled in the art detect and evaluate the optimal set of oil samples, and the corresponding target temperature value is corresponding to this historical feature data. In this way, simulate experiments on k sets of different historical feature data to obtain k sets of historical temperature adjustment data;

[0073] Optionally, the calculation formula for the prediction accuracy in this embodiment is: F y = ( C y - E y) 2 , where y is the number of the feature vector, F y is the prediction accuracy, C y is the predicted target temperature value corresponding to the y-th group of feature vectors, and E y is the actual target temperature value corresponding to the y-th group of feature vectors;

[0074] It is worth mentioning that the convergence criterion is determined by those skilled in the art according to the actual situation; the machine learning model in this implementation is a recurrent neural network (RNN), long short-term memory network (LSTM), gated recurrent unit (GRU) or other suitable models, which are not specifically limited herein.

[0075] The purpose of this embodiment is to analyze the change in oil temperature color and the change in the internal temperature of the pressing cage 1, control the temperature in the pressing cage 1, and ensure the quality of the pressed oil.
