[0050] The flip assembly 160 is connected to the lifting assembly 150 and is also electrically connected to the control module 140. The flip assembly 160 is used to drive the lifting assembly 150 to rotate, so that the filter bag 110 located at the material receiving position rotates together with the lifting assembly 150 to pour out the waste in the filter bag 110.

[0051] In this embodiment, the filter bag 110 is connected to the lifting assembly 150, and the control module 140 can control the lifting assembly 150 to drive the filter bag 110 to move up and down, so that the filter bag 110 can squeeze oil at the squeezing position and receive materials or pour out waste at the receiving position. The flip assembly 160 is used to control the lifting assembly 150 to rotate relative to the ground, so that the filter bag 110 can rotate with the lifting assembly 150, pour out the waste in the filter bag 110, and realize automatic unloading.

[0052] In some embodiments, the lifting assembly 150 includes a first driving member 151, a first transmission shaft 152, a second transmission shaft 153, and a conveyor belt 154. The driving end of the first driving member 151 is connected to the first transmission shaft 152. The conveyor belt 154 passes through the first transmission shaft 152 and the second transmission shaft 153. The filter bag 110 is connected to the conveyor belt 154. The first driving member 151 can drive the first transmission shaft 152 to rotate, so that the conveyor belt 154 drives the filter bag 110 to reciprocate between the receiving position and the extrusion position. Among them, the first driving member 151 is a driving motor, for example, it can be a reduction motor.

[0053] In this embodiment, the conveyor belt 154 passes through the first transmission shaft 152 and the second transmission shaft 153 respectively, and the driving end of the first driving member 151 is connected to the first transmission shaft 152, or the driving end of the first driving member 151 can also be connected to the second transmission shaft 153.

[0054] In some embodiments, the detection module 130 includes at least one position detection unit 131, which is electrically connected to the control module 140. At least one position detection unit 131 is passed through the first transmission shaft 152 and faces the filter bag 110. The position detection unit 131 is used to detect the position of the filter bag 110 and generate position information. The control module 140 is used to obtain the position information and control the filter bag 110 to move between the receiving position and the extrusion position according to the position information.

[0055] In this embodiment, the control module 140 obtains the position information of the filter bag 110 through the position detection unit 131, determines whether the filter bag 110 is located at the material receiving position, the extrusion position or a position between the material receiving position and the extrusion position according to the position information, and controls the filter bag 110 to accurately move to the corresponding position.

[0056] Specifically, the position detection unit 131 may be an optical displacement sensor, a photoelectric sensor, an ultrasonic sensor, a Hall sensor, a resistive sensor, or the like.

[0057] In some embodiments, the automatic oil pressing device 100 further includes a shell 170 , the lifting assembly 150 is disposed on the outer surface of the shell 170 , the squeezing assembly 120 is disposed in the shell 170 , the shell 170 has a first opening 171 , and the filter bag 110 can enter or move out of the shell 170 along the first opening 171 .

[0058] In this embodiment, the filter bag 110 is located outside the housing 170 when it is at the material receiving position, and is located inside the housing 170 when it is at the extrusion position. After the filter bag 110 receives the material at the material receiving position outside the housing 170, the control module 140 drives the filter bag 110 to enter the housing 170 along the first opening 171 through the lifting assembly 150, and after the filter bag 110 reaches the extrusion position, the extrusion assembly 120 is controlled to squeeze the oilseed in the filter bag 110. The housing 170 can collect the oil squeezed from the filter bag 110 for subsequent processing and transportation.

[0059] Furthermore, the detection module 130 includes at least one pressure detection unit 132 , which is electrically connected to the control module 140 . The pressure detection unit 132 is used to detect the weight of the lifting assembly 150 and the filter bag 110 and generate a first weight value and a second weight value.

[0060] The lifting assembly 150 also includes a support base 155, a first driving member 151, a first transmission shaft 152, a second transmission shaft 153 and a conveyor belt 154 are arranged on the support base 155, the support base 155 is arranged at the top of the shell 170, and the pressure detection unit 132 is arranged between the shell 170 and the support base 155.

[0061] In this embodiment, the lifting assembly 150 is connected to the filter bag 110 as a whole, and the lifting assembly 150 is arranged at the top of the housing 170. By arranging the pressure detection unit 132 between the housing 170 and the support seat 155 of the lifting assembly 150, the pressure detection unit 132 can detect the weight of the lifting assembly 150 and the filter bag 110. By detecting the overall weight of the lifting assembly 150 and the filter bag 110 before and after the oil seeds are added, the weight of the oil seeds added to the filter bag 110, that is, the first weight value, can be calculated. After the filter bag 110 is pressed, the overall weight of the lifting assembly 150 and the filter bag 110 is detected again to obtain the second weight value. The difference in weight detected by the pressure detection unit 132 before and after the oil pressing is calculated based on the first weight value and the second weight value, the oil pressing rate of the oil seeds in the filter bag 110 can be calculated, and then it can be judged whether the oil seeds are fully pressed. Among them, the pressure detection unit 132 is a pressure sensor.

[0062] like Figure 3 As shown, in some embodiments, the flip assembly 160 includes a second driving member 161 and a third transmission shaft 162, one end of the third transmission shaft 162 is connected to the driving end of the second driving member 161, and the other end is connected to the lifting assembly 150, the second driving member 161 can drive the third transmission shaft 162 to rotate, so that the lifting assembly 150 drives the filter bag 110 to rotate and pour out the waste in the filter bag 110.

[0063] In this embodiment, the second driving member 161 drives the third rotating shaft to drive the lifting assembly 150 to rotate relative to the outer shell 170, so that the filter bag 110 located on the lifting assembly 150 rotates together. After the opening of the filter bag 110 rotates to the direction facing the ground, the oilseed waste located in the filter bag 110 can be poured out, completing automatic unloading.

[0064] In some embodiments, the extrusion assembly 120 includes at least two extrusion members 121. When the filter bag 110 is in the extrusion position, the at least two extrusion members 121 are respectively arranged on both sides of the filter bag 110, and the surface of the extrusion member 121 facing the filter bag 110 has an uneven toothed structure.

[0065] In this embodiment, the squeezing assembly 120 includes two, four or more squeezing members 121. By arranging the squeezing members 121 opposite to each other in pairs, when the filter bag 110 is in the squeezing position, the squeezing members 121 can squeeze the oil seeds in the filter bag 110 when they are close to each other, and squeeze out the oil in the oil seeds. By arranging an uneven tooth structure on the surface of the squeezing member 121 facing the filter bag 110, the pressure of the squeezing member 121 on the oil seeds can be increased, the oil seeds can be crushed, and the oil extraction rate of the squeezing assembly 120 can be improved.

[0066] In some embodiments, the automatic oil pressing device 100 also includes a discharge container 180 and a first switch component 181, the first switch component 181 is electrically connected to the control module 140, the discharge container 180 is arranged on the side of the lifting component 150 away from the ground, and the discharge container 180 has a discharge port on the side close to the lifting component 150, and the first switch component 181 is arranged at the discharge port.

[0067] The control module 140 can control the first switch 181 to open or close the feed opening according to the detected first weight value or position information.

[0068] In this embodiment, the feed container 180 stores oil seeds. When the filter bag 110 is in the material receiving position, the control module 140 can control the first switch 181 to open, so that the oil seeds in the feed container 180 can be injected into the filter bag 110 .

[0069] When the weight of the oilseeds injected into the filter bag 110 does not reach the first weight value, the first switch 181 is kept open until the weight of the oilseeds in the filter bag 110 reaches the standard, and the control module 140 controls the first switch 181 to close, completing the feeding. The first switch 181 is an electric valve.

[0070] In some embodiments, the automatic oil pressing device 100 also includes an oil container 190 and a second switch 191, the second switch 191 is electrically connected to the control module 140, the oil container 190 is arranged on the side of the extrusion assembly 120 close to the ground, and the oil container 190 has a second opening on the side close to the extrusion assembly 120, and has an oil outlet on the side of the oil container 190 away from the extrusion assembly 120.

[0071] The oil flowing out of the filter bag 110 can flow into the oil container 190 through the second opening. The second switch 191 is arranged at the oil outlet. The control module 140 can control the second switch 191 to open the oil outlet according to the weight difference and the second threshold.

[0072] In this embodiment, the oil container 190 is used to receive the oil flowing out of the filter bag 110. After the filter bag 110 is fully squeezed and the weight difference reaches the second threshold, the control module 140 controls the second switch 191 to open, so that the oil in the oil container 190 can flow to the external container for the next processing.

[0073] Furthermore, a filter is provided between the bottom of the oil container 190 and the second switch 191, and the filter is used to filter impurities in the grease. By replacing the filter, the impurities accumulated in the oil container 190 can be removed to prevent blockage between the oil container 190 and the second switch 191.

[0074] The present invention also proposes an oil pressing method based on an automatic oil pressing device. For ease of understanding, the oil pressing method based on an automatic oil pressing device according to an embodiment of the present invention is described below. Figure 5 As shown, the oil pressing method based on the automatic oil pressing device in the embodiment of the present invention includes steps S110 to S160.

[0075] In step S110 , the oilseeds are controlled to flow into the filter bag 110 located at the receiving position.

[0076] In some optional embodiments, when the filter bag 110 is at the material receiving position, the first switch 181 of the discharge container 180 is controlled to open, and the oil seeds are injected into the filter bag 110 until the weight of the oil seeds in the filter bag 110 reaches the standard, and then the first switch 181 is closed.

[0077] In step S120 , a first threshold value and a first weight value of the filter bag 110 are obtained, wherein the first threshold value is a target weight of the oilseeds in the filter bag 110 , and the first weight value is an actual weight of the oilseeds in the filter bag 110 .

[0078] In step S130 , the pressing assembly 120 is controlled to press the filter bag 110 based on the first weight value and the first threshold value.

[0079] like Figure 6 As shown, step S130 includes step S131 and step S132.

[0080] In step S131, the first weight value is compared with the first threshold value. If the first weight value is less than the first threshold value, the oil seed injection into the filter bag 110 is continued. If the first weight value is greater than or equal to the first threshold value, the oil seed injection is stopped and the filter bag 110 is controlled to move from the receiving position to the squeezing position.

[0081] Specifically, Figure 7 As shown, step S131 includes step S1311 and step S1313.

[0082] In step S1311, if the first weight value is greater than or equal to the first threshold value, the injection of oilseeds is stopped and the filter bag 110 is controlled to move from the receiving position to the squeezing position;

[0083] In step S1312, the position information of the filter bag 110 during the movement is obtained;

[0084] In step S1313, based on the position information, it is determined whether the filter bag 110 has reached the squeezing position. If not, the filter bag 110 is controlled to continue moving toward the squeezing position until the filter bag 110 reaches the squeezing position.

[0085] In step S132 , the pressing assembly 120 is controlled to press the filter bag 110 located at the pressing position.

[0086] In this embodiment, when the filter bag 110 moves to the extrusion position, the position of the filter bag 110 is detected by the detection module 130 and the position information of the filter bag 110 is obtained. According to the position information, it is determined whether the filter bag 110 has reached the extrusion position. After the filter bag 110 reaches the extrusion position, the lifting assembly 150 is controlled to stop so that the filter bag 110 stays in the extrusion position. At this time, the filter bag 110 is located between the extrusion pieces 121 to facilitate the subsequent oil pressing process.

[0087] In step S140 , a second threshold value and a second weight value of the squeezed filter bag 110 are acquired.

[0088] In some optional embodiments, the second threshold is the target weight of oil squeezed from the oilseeds in the filter bag 110, and the second weight value is the weight of the oilseeds in the filter bag 110 after squeezing. The value of the second threshold can be preset. In the actual production process, taking tea oil seeds as an example, the oil extraction rate of tea oil seeds is 23.29% to 26.84%. Any value within the range of 23.29% to 26.84% can be set as the second threshold to determine whether the oilseeds are completely squeezed.

[0089] In step S150, a weight difference is calculated based on the first weight value and the second weight value.

[0090] In some optional embodiments, the weight of the oil squeezed from the oil seeds in the filter bag 110 can be obtained by calculating the weight difference between the second weight value and the first weight value, and the weight difference can be compared with the second threshold value to determine whether the oil seeds in the filter bag 110 are completely squeezed.

[0091] In step S160, whether the oilseeds are fully squeezed is determined based on the weight difference and the second threshold value. If the oilseeds are fully squeezed, the filter bag 110 is controlled to pour out the waste.

[0092] like Figure 8 As shown, step S160 includes steps S161 to S163.

[0093] In step S161 , the weight difference is compared with a second threshold value. If the weight difference is less than the second threshold value, the extrusion assembly 120 continues to be controlled to extrude the filter bag 110 . If the weight difference is greater than or equal to the second threshold value, the extrusion assembly 120 is controlled to stop extruding the filter bag 110 .

[0094] In step S162, the squeezed filter bag 110 is controlled to return from the squeezing position to the material receiving position.

[0095] In step S163, the filter bag 110 located at the material receiving position is controlled to pour out the waste material.

[0096] In this embodiment, if the calculated weight difference does not reach the second threshold, the squeezing assembly 120 is controlled to re-squeeze the oilseeds in the filter bag 110 until the weight difference reaches the second threshold. After squeezing is completed, the lifting assembly 150 is controlled to drive the filter bag 110 to return to the material receiving position, at which time the filter bag 110 is located outside the housing 170, and the flip assembly 160 is controlled to flip the filter bag 110 to pour out the waste material, thereby realizing automatic unloading.

[0097] Specifically, Fig. 9 As shown, step S162 includes step S1621 and step S1623.

[0098] In step S1621, the squeezed filter bag 110 is controlled to move from the squeezing position to the material receiving position.

[0099] In step S1622, the position information of the squeezed filter bag 110 during the moving process is obtained.

[0100] In step S1623, based on the position information, it is determined whether the squeezed filter bag 110 has reached the material receiving position. If not, the filter bag 110 is controlled to continue moving toward the material receiving position until the filter bag 110 reaches the material receiving position.

[0101] In this embodiment, the position of the filter bag 110 is detected in real time by the detection module 130 to ensure that the filter bag 110 is correctly in place, to avoid the filter bag 110 being out of place or off-position, resulting in failure to inject oil seeds or to press oil, and to ensure the normal operation of the automatic oil pressing device 100.

[0102] The specific process of the oil pressing method based on the automatic oil pressing device provided in the embodiment of the present invention is as follows:

[0103] In the first step, the detection module 130 detects whether the filter bag 110 is in the material receiving position;

[0104] In the second step, if the filter bag 110 is in the material receiving position, the first switch 181 is controlled to open, and the oil seeds in the discharge container 180 are injected into the filter bag 110. At the same time, the detection module 130 is used to detect whether the weight of the oil seeds injected into the filter bag 110 reaches a first threshold value. If not, the oil seeds continue to be injected. If the first threshold value is reached, the first switch 181 is closed.

[0105] The third step is to control the lifting assembly 150 to drive the filter bag 110 to move from the material receiving position to the extrusion position. At the same time, the detection module 130 detects whether the filter bag 110 is in place. If not, it continues to move to the extrusion position. If it is in place, the lifting assembly 150 is controlled to stop.

[0106] In the fourth step, the squeezing assembly 120 is controlled to squeeze the filter bag 110 at the squeezing position until the squeezed oil reaches the second threshold, and the detection module 130 detects the weight change after squeezing. If the calculated weight difference does not reach the second threshold after the first squeezing is completed, it proves that the squeezing is incomplete, and the squeezing assembly 120 is controlled to perform a second squeezing until the weight difference reaches the second threshold.

[0107] The fifth step is to control the extrusion assembly 120 to move away from the filter bag 110 after the weight difference reaches the second threshold value, and then control the lifting assembly 150 to drive the filter bag 110 to move from the extrusion position to the material receiving position. At the same time, the detection module 130 is used to detect whether the filter bag 110 is in place. If not, it continues to move toward the material receiving position. If it is in place, the lifting assembly 150 is controlled to stop.

[0108] The sixth step is to control the flip assembly 160 to flip the filter bag 110 at the receiving position, pour out the waste in the filter bag 110, complete automatic unloading, and control the filter bag 110 to flip and reset, waiting for the injection of oil seeds for the next round of oil pressing process.
