In addition, if there are terms such as "first", "second", etc., they are also used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0033] In addition, in the description of the present invention, unless otherwise clearly defined, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0034] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0035] This embodiment relates to a segmented screw oil press, the overall structure of which is as follows: Figure 1 , Figure 2 and Figure 3 As shown, it includes a pressing device 1, a stirring pot 3, a cake guiding device 2, and a gear box 4.

[0036] Among them, the stirring pot 3 is installed on the top of the pressing device 1, the stirring pot 3 and the pressing device 1 are respectively connected to a first conveying port 5 for conveying oil, the cake guiding device 2 is located on one side of the pressing device 1, the pressing device 1 and the cake guiding device 2 are respectively connected to a second conveying port 6 for conveying cake, the gear box 4 is located at one end of the pressing device 1, and the gear box 4 drives the pressing device 1, the stirring pot 3, and the cake guiding device 2 to move simultaneously.

[0037] The pressing device 1 includes a tail 101 installed on the gear box 4, a plurality of pressing cages 103 arranged at one end of the tail 101 away from the gear box 4, a head 102 for fastening the pressing cages 103 to the tail 101, and a pressing screw 104 rotating inside the head 102, the plurality of pressing cages 103, and the tail 101.

[0038] It is worth mentioning that the pressing device 1, the stirring pot 3, and the cake guide device 2 are respectively connected to the gear box 4 to ensure that they move simultaneously, thereby improving automation. The gear box 4 is internally connected with a plurality of gears with different speed ratios that mesh with each other. Figure 2 It can be seen that at least three output shafts 7 and one input shaft 8 extend out of the gear box 4. The input shaft 8 is connected to the motor through belts and pulleys. The three output shafts 7 are respectively connected to the pressing device 1, the stirring pot 3, and the cake guide device 2. The oil includes rapeseed, peanuts, soybeans and other plants that can be fried to produce oil. The cake is the residue left after the oil is squeezed out of the oil.

[0039] After the equipment is started, the oil is first placed in the stirring pot 3 for preheating. A heater is installed in the pressing device 1. The oil needs to be heated during oil pressing. The heater is a common heater in existing oil presses, so it is not mentioned in the drawings. The pressing device 1 can preheat the oil in the stirring pot 3, thereby improving the oil yield. Figure 3It can be seen that the oil enters the pressing device 1 through the first conveying port 5, and the pressing screw 104 and the pressing cage 103 cooperate to squeeze out the oil contained in the oil, and the oil flows out of the pressing cage 103. The pressing screw 104 can also drive the oil to move, and the oil is pressed while being conveyed. In this process, the oil becomes a cake, and the cake is discharged from the second conveying port 6 to the cake guiding device 2. The purpose of arranging multiple pressing cages 103 is to facilitate disassembly and assembly. The auger can be pulled out from the machine head 102, and then the pressing cages 103 can be removed one by one for inspection or cleaning.

[0040] Based on the above overall introduction, an exemplary structure of the segmented screw oil press of this embodiment is as follows: Figure 3 As shown, two tie rods 105 are screwed on the tail 101, and an arc groove 106 is provided at the bottom of the pressing cage 103 opposite to the tie rod 105. The arc groove 106 is placed on the tie rod 105, and the other end of the tie rod 105 passes through the head 102 and is tightened by a nut 107. It should be noted that the two tie rods 105 are located at one side of the bottom of the tail 101, and the pressing cage 103 can be directly placed on the tie rod 105. The arc groove 106 has the same diameter as the tie rod 105. Such a setting ensures that the pressing cage 103 is easy to install, and the nut 107 moves spirally on the tie rod 105 to ensure that the head 102 and the tail 101 can clamp multiple pressing cages 103.

[0041] As a preferred example, Figure 4 , Figure 6 and Fig.12 As shown, in this embodiment, through openings 108 for passing the two ends of the squeezing screw 104 are respectively opened on the head 102 and the tail 101. After one end of the squeezing screw 104 passes through the through opening 108 of the tail 101, it is connected to an output shaft 7 of the gear box 4 through a spline, and an adjusting component 109 for adjusting the squeezing screw 104 is threadedly provided at the through opening 108 of the head 102. Specifically, the through-openings 108 of the machine head 102 and the machine tail 101 are arranged coaxially to ensure that the pressing screw 104 can rotate inside the through-opening 108. A pressing chamber is opened inside the pressing cage 103, and the pressing screw 104 is inserted in the pressing box 110. The oil is pressed between the pressing box 110 and the pressing screw 104. The pressing box 110 is truncated cone-shaped, that is, the diameter gradually decreases from one end of the machine head 102 to one end of the machine tail 101. Such an arrangement can improve the oil yield. One end of the pressing screw 104 is arranged as a spline, and a keyway is opened on one of the output shafts 7 of the gear box 4. Such an arrangement ensures that the pressing screw 104 can be directly inserted into the output shaft 7. The adjusting component 109 can ensure the stability of the rotation of the pressing screw 104 and ensure that the pressing screw 104 and the output shaft 7 are in contact.

[0042] As a preferred example, Figure 5As shown, in this embodiment, shaft sleeves 111 that abut against the pressing cage 103 are respectively inserted into the through openings 108 of the head 102 and the tail 101, and the inner wall of the shaft sleeve 111 of the head 102 is set to be wavy, and a gap for the discharge of the material cake is left between the shaft sleeve 111 of the tail 101 and the pressing screw 104. Specifically, the shaft sleeve 111 of the head 102 can crush the oil material to facilitate the extrusion of oil, and the wavy setting can increase the friction between the oil materials, ensure that the oil materials are crushed, and improve the oil extraction efficiency. The shaft sleeve 111 of the tail 101 can facilitate the discharge of the material cake, and the role of the gap is to squeeze the material cake into blocks for easy collection.

[0043] As a preferred embodiment, Figure 6 As shown, the pressing cage 103 of this embodiment includes a cage 1031 that is interlocked and abutted with each other, a cage body 1032 inserted into the cage 1031, a pressing box 110 is opened in the cage body 1032, an arc groove 106 is opened at the bottom of the cage 1031, a guide groove 1033 is opened on the inner wall of the cage body 1032, and a through hole 1034 for outward flow is opened at the guide groove 1033 of the cage body 1032. It should be noted that the multiple cages 1031 are interlocked with each other, that is, grooves and bosses are respectively provided between two adjacent cages 1031, and the grooves and bosses are interlocked with each other. The cage 1031 and the cage body 1032 have the same length, ensuring that the multiple cages 1031 and the cage body 1032 can abut against each other. The pressing box 110 is opened along the center of the cage body 1032 to ensure that the pressing screw 104 can be inserted into the multiple pressing boxes 110. The arc groove 106 of the cage 1031 is opened at the pull rod 105 to ensure that the cage 1031 is easy to install. The opening of the guide groove 1033 and the through hole 1034 ensures that the squeezed oil can be discharged from the guide groove 1033 and the through hole 1034, ensuring that the squeezed oil is clear oil.

[0044] As a preferred example, Figure 7 As shown, in this embodiment, the tail 101 is provided with a discharge bin 112 connected to the through-hole 108, and a cake guide plate 113 rotatably arranged in the discharge bin 112, and the cake guide plate 113 is fixedly arranged on the output shaft 7 of the gear box 4. Specifically, the cakes are discharged from the through-hole 108 and fall into the discharge bin 112, and the cake guide plate 113 moves the cakes from the discharge bin 112 to the cake guide device 2, so that automatic discharge is realized.

[0045] As a preferred embodiment, Figure 8 and Fig.12As shown, the squeezing screw 104 of this embodiment includes a core shaft 1041 splined to the output shaft 7 of the gear box 4, a squeezing auger 1042 keyed to the core shaft 1041, a feeding auger 1043 keyed to the core shaft 1041 located inside the machine head 102, and a secondary auger 1044 arranged between the squeezing auger 1042. It should be noted that the feeding auger 1043 is located in the through-port 108 of the machine head 102, and the oil enters the through-port 108 of the machine head 102 from the first delivery port 5, and is transmitted to the pressing auger 1042 through the feeding auger 1043. The spiral blades of the pressing auger 1042 gradually become smaller from one end of the machine head 102 to one end of the machine tail 101. Such a setting can improve the oil yield. The spiral blades of the secondary auger 1044 have a smaller pitch than the spiral blades of the pressing auger 1042. With such a setting, when the material cake passes through the secondary auger 1044, the path is disrupted, and the material cake will be crushed and re-extruded by different paths when passing through, thereby improving the oil yield efficiency of the material cake, and the material cake is re-extruded after passing through the secondary auger 1044, thereby improving the cake formation rate of the material cake and avoiding the formation of debris.

Specifically, a thread is provided in the through-hole 108 of the machine head 102, and the adjusting seat 1091 is screwed on the thread. By rotating the adjusting seat 1091 on the thread, the core shaft 1041 and the output shaft 7 of the gear box 4 can be pushed to maintain abutment, thereby ensuring the stability of the rotation of the core shaft 1041. The first bearing 1093 adopts a thrust ball bearing, and the first bearing 1093 is installed between the pressure cover 1092 and the core shaft 1041 to ensure the smoothness of the rotation of the core shaft 1041. The second bearing 1094 adopts a rolling bearing, and the second bearing 1094 is installed between the pressure cover 1092 and the core shaft 1041 to ensure the stability of the core shaft 1041 during rotation. The adjusting seat 1091 is located at one end of the second bearing 1094 and is fixedly provided with a stop pad, which can ensure that the second bearing 1094 will not be displaced.
