Description

Technical Field

[0001] This utility model relates to the technical field of oil pressing feeding equipment, specifically an automatic feeding device for oil pressing equipment. Background Technology

[0002] Edible oil refers to animal or vegetable fats used in the food production process. Oil extraction is the process of pressing oilseed crops, which are classified into plant-based and animal-based raw materials. In general production, we mainly use plant-based raw materials, among which peanuts are a common raw material for oil extraction.

[0003] A search revealed that Chinese Patent Publication No. CN 212860602 U relates to the field of automatic feeding technology for edible oil pressing, specifically an automatic feeding machine for edible oil pressing. The machine includes a main body, a storage hopper, a control box, and a feeding pipe. The main body is equipped with casters at its bottom and a storage hopper on its top left side. Push rods are mounted on the base and back of the storage hopper. A feeding port is located on the top left side of the storage hopper, with a sealing cap embedded in the top of the feeding port. A guide slide plate is installed on the bottom of the inner wall of the storage hopper, and a first electric vibrating plate is embedded in the top right side of the guide slide plate. The overall structure is simple, facilitating large-scale feeding at once, continuous anti-clogging feeding, and efficient edible oil pressing. It also allows for precise calculation and control of the feeding amount, enabling accurate input of appropriate amounts of raw materials for edible oil pressing. The automatic feeding system is convenient, stable, and practical, possessing significant potential for wider application.

[0004] The oil pressing feeding device in the aforementioned patent still has certain shortcomings. The existing peanut oil pressing feeding device can only perform a simple feeding function, and it is difficult to remove shriveled, damaged, or empty shell particles contained in peanuts. As a result, shriveled and damaged peanuts are sent into the oil press, affecting the quality of the oil produced, and thus there are defects in its use. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an automatic feeding device for oil pressing equipment. This solves the problem that existing peanut oil pressing feeding devices can only perform a simple feeding function, while failing to remove shriveled, damaged, or empty shell particles from peanuts. As a result, shriveled and damaged peanuts are fed into the oil press, affecting the quality of the oil and causing defects in use.

[0006] This utility model provides the following technical solution: an automatic feeding device for oil pressing equipment, including a feeding buffer bin, with supporting legs evenly arranged around the bottom of the feeding buffer bin, a closing door provided on the side of the bottom of the feeding buffer bin, a material discharge port opened on the side of the top of the feeding buffer bin, an auger feeder installed at the bottom of the feeding buffer bin, the feeding port of the auger feeder being connected to the side of the bottom of the feeding buffer bin through a provided opening, and a feeding screening component provided at the top of the feeding buffer bin;

[0007] The feeding and screening assembly includes a top feeding hopper located at the top of the feeding buffer bin. A feeding channel is provided at the bottom of the top feeding hopper and is connected to the discharge port. A transmission rod is rotatably mounted inside the feeding channel, and three material-pulling blades are evenly arranged on the transmission rod. A drive motor is located on the outside of the top feeding hopper, and the drive shaft of the drive motor rotates through the inner wall of the top feeding hopper and is fixedly connected to the end of the transmission rod. An air supply channel is provided on the side wall of the feeding channel, and an air guide plate is provided inside the air supply channel. An air inlet is located on the outside of the air supply channel. A fan is located on the side of the top feeding hopper, and the outlet of the fan is connected to the air inlet via a connecting air supply pipe.

[0008] Preferred technical solution 1: The bottom end of the fan is fixedly connected to the top of the feeding buffer bin through a bottom support plate, and the side wall of the unloading channel is provided with a waste material discharge outlet.

[0009] Preferred technical solution 2: A debris baffle is provided on the top outer side of the debris discharge port, and a discharge guide plate is provided on the bottom side of the debris baffle.

[0010] Preferred technical solution 3: The bottom sidewall of the top hopper is inclined.

[0011] This design allows peanuts entering the top hopper to roll down to the discharge channel more quickly.

[0012] Preferred technical solution four: The air guide plate is inclined downward, and the debris discharge port is located on the side of the air supply channel.

[0013] This solution enables the air guide plate to compress and guide the airflow delivered by the fan into the air supply channel, resulting in a faster and more concentrated airflow velocity as it passes through the end of the air supply channel.

[0014] Preferred technical solution five: The debris baffle is L-shaped and bent.

[0015] This solution enables the airflow guided by the air guide plate to blow away the shriveled or empty peanuts passing through the feeding channel, and discharge them through the waste material outlet. The waste material baffle prevents the blown-away empty peanuts from scattering everywhere.

[0016] Compared with the prior art, this utility model provides an automatic feeding device for oil pressing equipment, which has the following beneficial effects:

[0017] This invention features a feeding and screening assembly at the top of the feeding buffer bin. The top hopper of this assembly has a feeding channel at its bottom, with an air supply channel and a waste discharge outlet on its inner wall. Airflow generated by a blower is delivered through the air supply channel to the feeding channel, removing shriveled or empty peanuts and ensuring that the peanuts entering the feeding buffer bin are plump. A screw conveyor at the bottom of the feeding buffer bin automatically feeds the air-selected peanuts into the oil press, resulting in higher quality peanuts entering the oil press and producing higher-quality peanut oil.

[0024] Please see Figure 1-4 ,

[0025] Example 1: An automatic feeding device for oil pressing equipment includes a feeding buffer bin 1. Support legs 2 are evenly arranged around the bottom of the feeding buffer bin 1. A closing door 3 is provided on the side of the bottom of the feeding buffer bin 1. A material discharge port 4 is opened on the side of the top of the feeding buffer bin 1. An auger feeder 5 is installed at the bottom of the feeding buffer bin 1. The feeding port of the auger feeder 5 is connected to the side of the bottom of the feeding buffer bin 1 through a set opening. A feeding screening component 6 is provided on the top of the feeding buffer bin 1.

[0026] The feeding and screening assembly 6 includes a top feeding hopper 601 located at the top of the feeding buffer bin 1. A feeding channel 602 is provided at the bottom of the top feeding hopper 601, which is connected to the discharge port 4. A transmission rod 603 is rotatably mounted inside the feeding channel 602, and three material-pulling blades 604 are evenly arranged on the transmission rod 603. A drive motor 605 is located on the outside of the top feeding hopper 601. The drive shaft of the drive motor 605 rotates through the inner wall of the top feeding hopper 601 and is fixedly connected to the end of the transmission rod 603. An air supply channel 606 is provided on the side wall of the feeding channel 602. An air guide plate 607 is installed inside the air duct 606. An air inlet chamber 608 is installed on the outside of the air supply duct 606. A fan 609 is installed on the side of the top discharge hopper 601. The air outlet of the fan 609 is connected to the air inlet chamber 608 through a connecting air supply pipe 610. The bottom end of the fan 609 is fixedly connected to the top of the feeding buffer chamber 1 through a bottom support plate 611. A waste material discharge outlet 612 is opened on the side wall of the discharge duct 602. A waste material baffle 613 is installed on the top of the outer side of the waste material discharge outlet 612. A discharge guide plate 614 is installed on the bottom side of the waste material baffle 613.

[0027] Example 2: The difference between this example and Example 1 is that the bottom sidewall of the top hopper 601 is inclined.

[0028] This allows the peanuts entering the top hopper 601 to roll down faster into the discharge channel 602 for discharge.

[0029] Example 3: The difference between this example and Example 1 is that the air guide plate 607 is inclined downwards, and the debris discharge port 612 is located on the side of the air supply channel 606.

[0030] This allows the air guide plate 607 to compress and guide the airflow delivered by the fan 609 to the air supply channel 606, resulting in a faster and more concentrated airflow velocity as it passes through the end of the air supply channel 606.

[0031] Example 4: The difference between this example and Example 1 is that the debris baffle 613 is L-shaped.

[0032] This allows the airflow guided by the air guide plate 607 to blow away the shriveled or empty peanuts passing through the feeding channel 602, and discharge them through the waste material discharge port 612. The waste material baffle 613 prevents the blown-away empty peanuts from scattering everywhere.

[0033] In this embodiment, the existing peanut oil pressing feeding device can only perform a simple feeding function, and it is difficult to remove shriveled, damaged or empty shell particles contained in peanuts. As a result, shriveled and damaged peanuts are sent into the oil press, affecting the quality of the oil produced, which is a defect in its use.

[0034] In summary, during specific implementation, when a user needs to feed peanuts into a peanut oil press, the user first needs to put the peanut raw materials into the top hopper 601 of the feeding and screening component 6. At this time, the drive motor 605 is started, which drives the transmission rod 603 to rotate. At this time, the opening diameter of the feeding channel 602 is approximately two peanut diameters. The transmission rod 603 uses the material-pushing plate 604 to push the peanuts falling into the top of the feeding channel 602 to promote their rapid entry into the feeding channel 602.

[0035] At the same time, the blower 609 starts. The airflow generated by the blower 609 is smaller than the weight of a normal peanut. The airflow is then transported to the air supply channel 606 through the air supply connecting pipe 610. After being compressed and guided by the air guide plate 607 in the air supply channel 606, the airflow can accelerate the blowing into the material discharge channel 602. The empty shells or shriveled peanuts in the peanuts passing through the side of the air supply channel 606 will be blown towards the waste material discharge outlet 612 and discharged under the blowing of the airflow.

[0036] Normal, plump peanuts can pass smoothly through the air supply channel 606 under their own weight and continue to fall in the feeding channel 602. They enter the feeding buffer bin 1 through the discharge port 4. Since the feeding buffer bin 1 is funnel-shaped, a screw conveyor 5 is installed at the bottom of the feeding buffer bin 1. The discharge port at the bottom of the feeding buffer bin 1 is connected to the inlet of the screw conveyor 5, so that the peanut raw materials after air separation can enter the screw conveyor 5. The screw conveyor 5 automatically feeds the peanuts into the oil press.

[0037] Compared to traditional feeding devices, this device can effectively remove shriveled or empty shells from peanut raw materials, resulting in better quality peanut oil pressed from peanuts automatically fed by the auger feeder 5.
