[0001] This invention relates to the field of vegetable oil conveying devices, and particularly to a conveying device for vegetable oil production and processing. Background Technology

[0002] Vegetable oil is one of the most important raw materials in food processing, and edible oil is the direct manifestation of vegetable oil in cooking and food consumption. There are many types of vegetable oils, such as soybean oil, rapeseed oil, palm oil, and sunflower seed oil. They are oils extracted from plant fruits, seeds, or germs and are the cornerstone of the food industry. In the production and processing of vegetable oils, conveying devices are key equipment connecting raw material handling, filling, and transfer stages. They are mainly used to automate the transfer of oil or finished oil containers to improve production efficiency and reduce manual intervention.

[0003] In actual production, there are many types of vegetable oils (such as rapeseed oil and peanut oil), but existing production lines can usually only transport a single type of oil and cannot fill two different types of oil at the same time, resulting in low production flexibility.

[0037] Reference Figures 1-6 A conveying device for vegetable oil production and processing is disclosed, which transports oil to an oil drum 1. The device includes the oil and the oil drum 1 for holding the oil. Vegetable oil is one of the most important raw materials in food processing, and edible oil is the direct manifestation of vegetable oil in cooking and food consumption. There are many types of vegetable oils, such as soybean oil, rapeseed oil, palm oil, and sunflower seed oil. They are oils extracted from plant fruits, seeds, or germs and are the cornerstone of the food industry. In the vegetable oil production and processing process, the conveying device is a key piece of equipment connecting raw material handling, filling, and transfer stages. It is mainly used to automate the transfer of oil or finished oil drum 1. It should be noted that the oil drum 1 has two states: an empty oil drum 1 without oil and a full oil drum 1 with oil. The terms "empty oil drum 1" and "full oil drum 1" mentioned below refer to both states.

[0038] Conveying assembly 2 is used to convey oil drum 1. Conveying assembly 2 includes a conveyor frame 21, a flat conveyor belt 22 drivenly connected to the conveyor frame 21, a through-beam photoelectric switch 23 mounted on the conveyor frame 21, a counter 24 electrically connected to the through-beam photoelectric switch 23, a rotary cylinder 25 mounted on the side of the conveyor frame 21 away from the through-beam photoelectric switch 23, and a stop bar 26 rotatably connected to the output end of the rotary cylinder 25. The stop bar 26 is used to limit and block the oil drum 1.

[0039] Conveying assembly 2 (3) and conveying assembly 3 (4) are respectively located on one side of conveying assembly 1 (2) and are used to convey oil drums 1 after oil loading. Conveying assembly 2 (3) and conveying assembly 3 (4) use flat conveyor belts 22 for conveying, just like conveying assembly 1 (2).

[0040] The conveying and filling device is located on the side of the conveying component 2 away from the conveying component 3. The conveying and filling device includes a support truss 51, a workbench 52 mounted on the support truss 51, a fixed truss 53 fixedly connected to the workbench 52, a first conveying pipe 54 and a second conveying pipe 55 mounted on the fixed truss 53, a switching component 56 mounted at one end of the first conveying pipe 54 and the second conveying pipe 55, and a filling component 57 mounted on the fixed truss 53.

[0041] The switching assembly 56 includes a third conveying pipe 561 and a fourth conveying pipe 562 mounted on a support truss 51, a support member 563 fixedly connected between the third conveying pipe 561 and the fourth conveying pipe 562, a baffle 564 rotatably connected to the inner wall of the support member 563, a servo motor 565 mounted on one side of the third conveying pipe 561, and a rotating shaft 566 mounted on the output end of the servo motor 565. The baffle 564 is connected to the rotating shaft 566. The first conveying pipe 54 and the second conveying pipe 55 are respectively connected to the third conveying pipe 561 and the fourth conveying pipe 562. The diameter of the baffle 564 is the same as the inner diameter of the third conveying pipe 561 and the fourth conveying pipe 562. It should be noted that the third conveying pipe 561, the fourth conveying pipe 562, the first conveying pipe 54, and the second conveying pipe 55 are all made of corrosion-resistant metal.

[0042] Both the third conveying pipe 561 and the fourth conveying pipe 562 are provided with a connection port 8 at one end. The switching component 56 is connected to the output end of the external oil supply equipment through the connection port 8 and the connecting pipe.

[0043] Cleaning assembly 6, installed on switching assembly 56, is used to clean conveying pipe 1 54 and conveying pipe 2 55. Cleaning assembly 6 includes a water conveying pipe 61 installed on one side of supporting truss 51, a cover plate 1 62 rotatably connected to one end of water conveying pipe 61, a rotating baffle 63 fixedly connected to one end of cover plate 1 62, a vertical plate 64 installed on supporting truss 51, a servo motor 2 65 installed on vertical plate 64, a rotating shaft 2 66 installed at the output end of servo motor 2 65, a driving gear 67 installed on the outer wall of rotating shaft 2 66, and a driven gear ring 68 meshing with driving gear 67. Cover plate 1 62 is installed on the inner wall of driven gear ring 68. One side of cleaning assembly 6 is provided with water conveying channel 1 9 and water conveying channel 2 10. Water conveying channel 1 9... Water supply channel 2 10 is connected to water supply pipeline 3 561 and water supply pipeline 4 562 respectively; control valves 11 are installed inside water supply channels 1 9 and 2 10; it should be noted that water supply pipeline 1 9, water supply pipeline 2 10, and water supply pipeline 61 are all made of corrosion-resistant metal; taking the cleaning water supply pipeline 1 54 as an example, the servo motor 2 65 is started to drive the drive gear 67 to rotate through the rotating shaft 2 66. The drive gear 67 rotates and meshes with the driven gear ring 68, driving the driven gear ring 68 to rotate. The rotation of the driven gear ring 68 drives the cover plate 1 62 on its inner wall to rotate. The rotation of the cover plate 1 62 drives the rotating baffle 63 to rotate, thereby disengaging the rotating baffle 63 from one end opening of water supply channel 1 9, and is controlled by PLC. Device 12 opens control valve 11, thereby connecting the cavity between water supply channel 1 9 and conveying pipe 3 561. A cover plate 2 is installed at the other end of water supply pipe 61, with a connecting part on cover plate 2. This connecting part allows water supply pipe 61 to be connected to external water supply equipment. The external water supply equipment is then activated to supply water to the inside of water supply pipe 61. The water inside water supply pipe 61 flows through water supply channel 1 9 to conveying pipe 3 561 and conveying pipe 1 54, and finally exits from the outlet of conveying pipe 1 54, thus achieving the purpose of cleaning conveying pipe 1 54 separately. The method for cleaning conveying pipe 2 55 separately is the same as for conveying pipe 1 54, and therefore will not be described in detail. If it is necessary to clean conveying pipe 1 54 and conveying pipe 3 561 simultaneously... When cleaning is performed in channel 2 55, the drive servo motor 1 565 is started. The servo motor 1 565 drives the baffle 564 to rotate upward inside the support member 563 through the rotating shaft 1 566. A sealing element is set at the arc-shaped groove position opened in the support member 563. Then, the external water supply equipment is started to supply water into the water supply pipe 61, and the control valve 11 on the water supply channel 1 9 and the water supply channel 2 10 is opened. Thus, the water inside the water supply pipe 61 flows to the conveying pipe 3 561 or the conveying pipe 4 562 through the water supply channel 1 9 or the water supply channel 2 10. Since the conveying pipe 3 561 and the conveying pipe 4 562 are connected at this time, the water is transported to the conveying pipe 1 54 and the conveying pipe 2 55 for simultaneous cleaning, which is convenient to use.

[0044] The filling assembly 57 includes a telescopic cylinder 571 mounted on a fixed truss 53 and a filling head 572 mounted on the output end of the telescopic cylinder 571. The filling head 572 is connected to the first delivery pipe 54 and the second delivery pipe 55 via a hose. When the telescopic cylinder 571 is activated, the filling head 572 is driven to descend and engage with the opening of the oil drum 1, thereby filling the oil into multiple empty oil drums 1. The filling assembly 57 is the same as the existing technology and is a relatively mature product. Therefore, its specific working principle, structure and how to achieve accurate metering and filling of oil will not be described in detail.

[0045] The transfer assembly 7, installed on the workbench 52, is used to sequentially transport the oil drums 1 that have been loaded with oil to the second conveying assembly 3 and the third conveying assembly 4 for transfer. The transfer assembly 7 includes a telescopic cylinder 2 71 installed on the workbench 52 and a push plate 72 installed at the output end of the telescopic cylinder 2 71. When the telescopic cylinder 2 71 is activated, it pushes the two full oil drums 1 to the direction of the second conveying assembly 3 and the third conveying assembly 4 respectively through the push plate 72, so that the full oil drums 1 are transported by the second conveying assembly 3 and the third conveying assembly 4 to the next process.

[0046] It also includes a PLC controller 12, which is mounted on the conveyor frame 21; used to control the operation of all electronic equipment on the device.

[0047] Working principle: Taking the conveying of six empty oil drums 1 as an example, the first working mode is when the six empty oil drums 1 are filled with different types of oil. First, the flat conveyor belt 22 of the conveying component 2 transports the empty oil drums 1. When the empty oil drum 1 is transported by the flat conveyor belt 22 past the through-beam photoelectric switch 23, it is detected by the through-beam photoelectric switch 23. The through-beam photoelectric switch 23 is connected to the counter 24 through the wire, so the counter 24 counts the empty oil drums 1. When the first oil drum 1 is transported by the flat conveyor belt 22 and one side of its sidewall abuts against the side of the stop bar 26, the position of the first oil drum 1 is detected. The limit switch is activated, while the flat conveyor belt 22 continues to convey oil. When the counter 24 counts six empty oil drums 1, the flat conveyor belt 22 stops conveying oil. At this time, the six empty oil drums 1 correspond to six filling components 57 respectively. The telescopic cylinder 571 is activated to drive the filling head 572 to descend. The filling head 572 connects to the opening of the oil drum 1. The conveying pipes 3 and 4 are connected to two external oil supply devices respectively. The two oil supply devices supply different oils to the conveying pipes 3 and 4 respectively. The two sets of external oil supply devices are activated, and one set of oil supply devices connects to the conveying pipe 3 561. One end of the connection port 8, connecting pipe, conveying pipe three 561, and conveying pipe one 54 supplies oil to the three sets of filling components 57 connected to conveying pipe one 54. The oil can be rapeseed oil or other edible vegetable oil. The other oil supply device supplies oil to the three sets of filling components 57 connected to conveying pipe two 55 through one end of the connection port 8, connecting pipe, conveying pipe four 562, and conveying pipe two 55. The oil can be peanut oil or other edible vegetable oil. Thus, two different types of oil are simultaneously fed into six empty oil drums 1. After filling is completed, two telescopic air valves are activated. Cylinder 2 71 drives push plate 72 to move. The two push plates 72 push the full oil drum 1, which has been filled with oil, onto conveying component 2 3 and conveying component 3 4 respectively for conveying. That is, the two products filled with different oils are conveyed separately. Then, the PLC controller 12 continues to drive the flat conveyor belt 22 to convey. At this time, another set of full oil drums 1 abuts against one side of the stop bar 26. The two products filled with different oils are conveyed separately by the transfer component 7. At the same time, the empty oil drum 1 continues to be conveyed, and the counter 24 counts again, thereby achieving the purpose of continuously filling the empty oil drum 1 with oil, discharging the full oil drum 1, and replenishing the empty oil drum 1.

[0048] The second method involves simultaneously transporting the same oil through both transport pipe 1 (54) and transport pipe 2 (55). Before transporting, either transport pipe 1 (54) or transport pipe 2 (55) needs to be cleaned. Taking the cleaning of transport pipe 1 (54) as an example, the following detailed explanation is provided: Servo motor 2 (65) is started, driving the drive gear 67 to rotate via shaft 2 (66). The drive gear 67 meshes with the driven gear ring 68, causing it to rotate. The rotation of the driven gear ring 68 causes the cover plate 1 (62) on its inner wall to rotate. The rotation of cover plate 1 (62) causes the rotating baffle 63 to rotate, thus disengaging the rotating baffle 63 from one end of the water supply channel 1 (9) and opening the control valve 11. This allows the cavity between water supply channel 1 (9) and transport pipe 3 (561) to connect. The other end of the water supply pipe 61 is equipped with cover plate 2, which has a connecting part. This connecting part allows the water supply pipe 61 to be connected to external water supply equipment. The external water supply equipment is then started to supply water to the inside of the water supply pipe 61. Water inside pipe 61 flows through water supply pipe 19 to conveying pipe 3 561 and conveying pipe 1 54, and finally exits from the outlet of conveying pipe 1 54, thereby achieving the purpose of cleaning conveying pipe 1 54 and avoiding cross-contamination. Then, control valve 11 is closed, and servo motor 1 565 is started. Servo motor 1 565 drives baffle 564 to rotate upward inside support member 563 through rotating shaft 1 566. A sealing element is set at the arc groove position of support member 563 to prevent oil leakage. Then, the external oil supply equipment is started to supply oil into conveying pipe 3 561. The oil inside conveying pipe 3 561 flows through the lower surface of baffle 564 into conveying pipe 4 562. Thus, conveying pipe 3 561 and conveying pipe 4 562 simultaneously deliver the same type of oil into conveying pipe 1 54 and conveying pipe 2 55. The oil is then filled into empty oil tank 1 through six filling components 57, making it convenient to use.

[0049] This device is highly integrated and can meet different usage needs within a certain range. It can fill two different types of oil at the same time, or fill only one type of oil, which is convenient to adjust according to actual production needs, effectively improving the practicality and ease of use of the device.

[0050] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
