Through the arrangement of the magnetic suction rods 8, the impure metal substances in the raw materials in the screening box 1 can be effectively adsorbed, effectively ensuring that the screened raw materials are at a higher specification.

[0027] Further as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, it is worth specifically explaining that the screening assembly 7 includes a mounting plate 71, which is fixed to the inner side wall of the screening box 1, and a driven shaft 72 is rotatably connected to the side wall of one side of the mounting plate 71, and a cam 73 is tightly sleeved on the outer surface of the driven shaft 72, and two symmetrically distributed extrusion plates 74 are fixed to the side wall of the bottom end of the screening plate 2, and the extrusion plates 74 are located on both sides of the cam 73, and a driving shaft 75 is rotatably connected to the inner side wall of the screening box 1, and bevel gears 76 are provided between the driving shaft 75 and the driven shaft 72, and the two bevel gears 76 are meshed and connected; a servo motor 77, the servo motor 77 is fixed to the outer side wall of the screening box 1, and one end of the output shaft of the servo motor 77 is coaxially fixed to the driving shaft 75, and the bottom end side wall of the screening plate 2 is fixed There are two symmetrically distributed connecting plates 78, and two symmetrically distributed dampers 79 are fixed to the side wall of one side of the connecting plate 78. One end of the damper 79 away from the connecting plate 78 is fixed to the inner side wall of the screening box 1. A spring 710 is sleeved on the outer surface of the damper 79. One end of the spring 710 is fixed to the side wall of one side of the connecting plate 78, and the other end of the spring 710 is fixed to the inner side wall of the screening box 1. Through the setting of the screening component 7, the screen plate 2 can be driven to move back and forth left and right, thereby effectively improving the screening efficiency of the raw materials, being more able to meet the needs of a large number of raw material screening work, ensuring that the screened raw materials can meet the needs of the staff, not only with high screening efficiency but also effectively improving the processing quality of vegetable oil.

[0028] Further as Figure 3 As shown, it is worth explaining in detail that two symmetrically distributed guide rods 9 are fixed to the side wall of one side of the connecting plate 78, and the guide rods 9 are slidably penetrated by the side wall of one side of the screening box 1. A limiting ring 10 is fixed to one end of the guide rod 9. Through the setting of the guide rod 9, a guiding and limiting function is played on the screen plate 2, which effectively ensures that the screen plate 2 can move in a relatively stable state.

[0029] The present scheme has the following working process: when the raw materials for vegetable oil processing need to be screened and pre-selected, the raw materials are first poured into the feed hopper 3, causing the raw materials to fall onto the sieve plate 2, and the metal substances in the raw materials are attracted by the magnetic attraction of the magnetic attraction rod 8, and the driving shaft 75 is driven by the servo motor 77 to rotate synchronously, and the meshing transmission effect of the bevel gear 76 is used to drive the driven shaft 72 to rotate synchronously, causing the cam 73 to rotate synchronously, and the extrusion transmission effect between the cam 73 and the extrusion plate 74 is used to make the sieve plate 2 subjected to force. Then it moves back and forth left and right, and the elastic effect of the damper 79 and the spring 710 is used to ensure that the cam 73 and the extrusion plate 74 are always in a fit state, so that the screen plate 2 moves back and forth left and right after being stressed, and the raw materials are shaken and screened. The transmission effect of the pulley 14 and the belt 15 is used to make the rotating shaft 12 rotate synchronously, driving the frame-type stirring rod 13 to rotate synchronously, thereby breaking up the principle on the top surface of the screen plate 2, and the screened raw materials fall into the discharge hopper 6 and are discharged from the discharge hopper 6.

[0030] According to the above working process, it can be known that: through the setting of the screening component 7, the screen plate 2 can be driven to move back and forth left and right, thereby effectively improving the screening efficiency of the raw materials, and can better meet the needs of a large number of raw material screening work, ensuring that the screened raw materials can meet the needs of the staff. Not only is the screening efficiency high, but it also effectively improves the processing quality of vegetable oil. The brush roller is forced to continuously clean the screen plate 2 in the left and right directions, which can avoid the situation where the screen plate 2 is not smooth or even blocked, greatly improving the screening effect of the raw materials, and preventing the raw materials from being blocked or stuck during screening. It is very practical.

[0031] Further as Figure 3 and Figure 4 As shown, it is worth explaining in detail that two symmetrically distributed guide plates 11 are fixed to the inner side wall of the screening box 1, and the vertical cross-section of the guide plate 11 is arranged in a trapezoidal shape. One side of the guide plate 11 is in contact with the top surface of the sieve plate 2. Through the arrangement of the guide plate 11, it can be ensured that the raw materials can slide to the sieve plate 2 in a concentrated manner, and the raw materials can be prevented from falling into the dead corner between the sieve plate 2 and the guide plate 11.

[0032] Further as Figure 5 and Figure 6As shown, it is worth explaining in detail that the inner side wall of the screening box 1 is rotatably connected to a rotating shaft 12, and a plurality of frame-type stirring rods 13 distributed in a circle are fixed to the outer surface of the rotating shaft 12. A pulley 14 is arranged between the rotating shaft 12 and the driving shaft 75, and a belt 15 is commonly sleeved on the outer surfaces of the two pulleys 14. The stirring rods are driven by the operation of the rotating shaft 12 to break up the raw materials at the top surface of the screen plate 2, which can accelerate the screening efficiency of the raw materials to a certain extent, and can avoid the accumulation and blockage of the principles, which has a better screening effect than vegetable oil raw materials.

[0033] Further as Figure 2 and Figure 3 As shown, it is worth explaining in detail that the vertical section of the feed hopper 3 is arranged in an inverted trapezoidal shape, and a mounting groove 16 is provided on the side wall of one side of the screening box 1. A sealing side plate 17 is rotatably connected inside the mounting groove 16. Through the setting of the sealing side plate 17, the accumulated impurities on the screen plate 2 can be effectively cleaned, which is convenient for the staff to carry out cleaning work. Through the setting of the feed hopper 3, it is ensured that the raw materials entering the screening box 1 are more concentrated.

[0034] In summary: through the setting of the magnetic suction rod 8, the impurity metal substances in the raw materials in the screening box 1 can be effectively adsorbed, effectively ensuring that the screened raw materials are at a higher specification, and through the setting of the guide rod 9, it plays a guiding and limiting role on the screen plate 2, effectively ensuring that the screen plate 2 can move in a relatively stable state, and through the setting of the guide plate 11, it can ensure that the raw materials can slide to the screen plate 2 in a concentrated manner, and can avoid the raw materials from falling into the dead corner between the screen plate 2 and the guide plate 11, and through the operation of the rotating shaft 12 to drive the stirring rod, the raw materials at the top surface of the screen plate 2 can be scattered, which can accelerate the screening efficiency of the raw materials to a certain extent, and can avoid the accumulation and blockage of the principle. Compared with vegetable oil raw materials, the screening effect is better, and through the setting of the sealing side plate 17, the accumulated impurities at the screen plate 2 can be effectively cleaned, which is convenient for the staff to carry out cleaning work, and through the setting of the feed hopper 3, it is ensured that the raw materials entering the screening box 1 are more concentrated.

[0035] The servo motor 77 can be purchased on the market. The servo motor 77 is equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so it will not be repeated in the specification.
