Description

Technical Field

[0001] This application relates to the technical field of feeding devices, and in particular to an automatic feeding device for an oil extractor. Background Technology

[0002] Currently, centrifugal oil separators are devices that utilize the principle of centrifugal force to remove oil from materials. They are widely used in industries such as food processing, chemicals, pharmaceuticals, and metallurgy. Through the powerful centrifugal force generated by high-speed rotation, they separate liquids (such as oil, water, or other liquids) from solid materials, thereby achieving the purpose of oil removal, dehydration, or drying.

[0003] Oil extractors typically require a feeding device to automatically feed materials into the machine. Traditional feeding devices mainly consist of a base with a rotating conveyor belt. A feeding hopper is located on one side of the conveyor belt. Materials are fed into the hopper and eventually fall onto the conveyor belt, which then transports the material. However, for fasteners such as screws and nuts, the limited size of the discharge opening at the bottom of the feeding hopper often leads to jamming during the actual feeding process. If the discharge opening is blocked, the conveyor belt cannot feed material into the oil extractor, thus affecting the oil extraction efficiency. Utility Model Content

[0004] This application provides an automatic feeding device for an oil extractor, which can effectively reduce the probability of material jamming and ensure that the material can be smoothly fed into the discharge hopper, thereby ensuring the oil extraction efficiency.

[0005] The automatic feeding device for an oil extractor provided in this application adopts the following technical solution:

[0007] Preferably, a reset torsion spring is sleeved on the outside of the rotating shaft of the tilting frame. One end of the reset torsion spring is fixedly connected to the machine base, and the other end of the reset torsion spring is fixedly connected to the tilting frame. The reset torsion spring is used to drive the tilting frame to rotate to the state of closing the discharge port of the feed frame.

[0008] Preferably, a lifting platform is provided inside the machine base, and the hopper is disposed on the lifting platform; a chain is rotatably disposed inside the machine base, the chain is symmetrically disposed on both sides of the lifting platform, the lifting platform is fixedly disposed on the chain on both sides, and the chain is used to drive the lifting platform to move up and down.

[0009] Preferably, a bearing seat is rotatably provided on the outer side wall of the lifting platform, and a limiting slide is provided on the inner side wall of the base facing the bearing seat, the length of which extends along the lifting direction of the lifting platform; the bearing seat is limited and rotatably disposed within the limiting slide.

[0010] Preferably, the bottom of the hopper is rotatably mounted on the lifting platform, the top of the hopper is provided with a limit rod, the base is provided with a guide seat located above the limit rod, the guide seat is located on the upward path of the limit rod, the guide seat is provided with a guide groove for the limit rod to move into, and the guide seat is used to guide the hopper to rotate on the lifting platform.

[0011] Preferably, the bottom wall of the feed rack has multiple chip removal grooves.

Detailed Implementation

[0024] The present application will be further described in detail below with reference to the accompanying drawings.

[0025] This application discloses an automatic feeding device for an oil extractor.

[0026] Reference Figure 1 , Figure 2 The automatic feeding device of the oil extractor includes a base 1, a hopper 2 for lifting materials is installed inside the base 1, and a feeding rack 3 for conveying materials into the hopper 2 is fixedly installed outside the base 1. The discharge port of the feeding rack 3 faces the hopper 2.

[0027] like Figure 3 , Figure 4 As shown, two sets of symmetrically arranged chains 10 are rotatably mounted inside the base 1, and sprockets 100 that mesh with the chains 10 are rotatably mounted on the inner side wall of the base 1. A linkage rod 101 is coaxially fixedly connected between the two opposing sprockets 100. A servo motor with an output shaft coaxially fixedly connected to the linkage rod 101 is fixedly mounted on the top outer side wall of the base 1. The servo motor is used to drive the linkage rod 101 to rotate in the forward or reverse direction. As the linkage rod 101 rotates, the sprockets 100 can drive their respective chains 10 to rotate synchronously.

[0028] like Figure 2 , Figure 4As shown, a lifting platform 7 is located between two chains 10 on both sides of the base 1. The lifting platform 7 is fixedly installed on one side of its respective opposite chain 10, and the chains 10 are used to drive the lifting platform 7 to move up and down within the base 1. Bearing seats 70 are rotatably mounted on the outer wall of the lifting platform 7. The bearing seats 70 are arranged in pairs, symmetrically on the left and right sides of the lifting platform 7. The two bearing seats 70 in the same group are arranged at intervals along the lifting direction of the lifting platform 7. Limiting slides 11 are integrally formed on the inner wall of the base 1 facing each group of bearing seats 70. The length of the limiting slides 11 extends along the lifting direction of the bearing seats 70. The bearing seats 70 are limited and rotatably mounted in their respective opposite limiting slides 11. During the lifting process, the rolling of the bearing seats 70 on both sides can reduce the friction experienced by the bearing seats 70 during lifting. In addition, under the limitation of the limiting slides 11, the stability of the lifting platform 7 during lifting can be further improved, and unnecessary displacement of the lifting platform 7 can be reduced.

[0029] like Figure 4 , Figure 5 As shown, the bottom of the hopper 2 is rotatably mounted on the lifting platform 7, and the length direction of the rotation axis of the hopper 2 is consistent with the length direction of the linkage rod 101. A limiting rod 21 parallel to the linkage rod 101 is fixedly installed on the top of the hopper 2. A guide seat 22 located above the limiting rod 21 is fixedly installed on the machine base 1, and the guide seat 22 is located on the upward path of the limiting rod 21. The guide seat 22 is provided with a guide groove 23 for the limiting rod 21 to move out of the machine base 1. The guide seat 22 is used to limit the further upward movement of the limiting rod 21 and guide the hopper 2 to rotate around the lower rotation axis on the lifting platform 7 until all the material in the hopper 2 is poured out into the feed inlet at the top of the oil extractor.

[0030] Subsequently, the servo motor will drive the chain 10 to rotate in the opposite direction. At this time, the lifting platform 7 will drive the hopper 2 to move down synchronously under the drive of the chain 10. When the limit rod 21 exits from the guide groove 23, the hopper 2 will automatically reset under its own gravity to prepare for the next feeding process.

[0031] like Figure 5 , Figure 6As shown, the bottom inner wall of the feed rack 3 is inclined downwards towards the base 1, and multiple chip removal grooves 30 are formed on the bottom wall of the feed rack 3 away from the base 1. Mounting brackets 8 are fixedly installed on the base 1 on both sides of the feed rack 3. A vibrator 4 is fixedly installed on the top of the mounting brackets 8. The vibrator 4 can be a commercially available electromagnetic vibrator, whose core components are an electromagnet and a permanent magnet or another electromagnet connected to the vibrating body. When alternating current passes through the electromagnet, a changing magnetic field is generated. This magnetic field interacts with the magnet fixed to the vibrating body, thereby generating an attractive or repulsive force. This attractive or repulsive force changes periodically with the change of current, causing the vibrating body to produce reciprocating or rotating motion, thus achieving vibration. The vibrator 4 is fixedly mounted on the top of the feed rack 3 and is used to drive the feed rack 3 to vibrate synchronously.

[0032] During operation, the vibrator 4 drives the feeding rack 3 to vibrate synchronously. As the feeding rack 3 vibrates, materials placed on it, such as screws and nuts, are conveyed along the inclined bottom wall of the feeding rack 3 towards the machine base 1. This effectively reduces the probability of material jamming, ensuring that the material can be smoothly fed into the discharge hopper 2, thereby guaranteeing degreasing efficiency and continuous feeding. With the vibration of the feeding rack 3, fine debris carried in the material can be removed from the material through the chip discharge trough 30, thus improving the cleanliness of the material.

[0033] like Figure 5 , Figure 6 As shown, a tilting frame 5 is rotatably mounted outside the discharge port of the feeding frame 3, facing the dumping hopper 2. The tilting frame 5 is used to control the opening and closing of the discharge port of the feeding frame 3. When the tilting frame 5 rotates to the vertical position, the discharge port of the feeding frame 3 will be blocked by the tilting frame 5 and be in a closed state, so the material cannot fall from the discharge port of the feeding frame 3.

[0034] like Figure 5 , Figure 6 As shown, the outside of the tilting frame 5 is rotatably equipped with a pressure plate 6 facing the hopper 2. The pressure plate 6 is in a drooping state under its own weight. The pressure plate 6 in the drooping state is located on the downward path of the hopper 2. The pressure plate 6 is used to drive the tilting frame 5 to tilt towards the hopper 2.

[0035] like Figure 5 , Figure 6 As shown, a reset torsion spring 50 is sleeved on the outside of the rotating shaft of the tilting frame 5. One end of the reset torsion spring 50 is connected and fixed to the machine base 1, and the other end of the reset torsion spring 50 is connected and fixed to the tilting frame 5. In its natural state, the reset torsion spring 50 is used to drive the tilting frame 5 to rotate to the state of closing the discharge port of the feed frame 3.

[0036] As the hopper 2 gradually descends under the synchronous drive of the chains 10 on both sides, it pushes the pressure plate 6 downwards. At this time, the tilting frame 5, pulled by the pressure plate 6, overcomes the torque of the return torsion spring 50 and gradually tilts towards the hopper 2 until it reaches a horizontal position. Material can then fall from the open feed rack 3 outlet onto the tilting frame 5 and finally into the hopper 2, thus completing the automatic feeding process. As the hopper 2 gradually rises under the synchronous drive of the chains 10 on both sides, the tilting frame 5 gradually rotates back to its original position under the return force of the return torsion spring 50 until the feed rack 3 outlet closes again. The entire feeding process is completed automatically, effectively preventing material jamming.

[0037] The operating principle is as follows: During operation, the vibrator 4 drives the feeding rack 3 to vibrate synchronously. As the feeding rack 3 vibrates, materials placed on it, such as screws and nuts, are conveyed along the inclined bottom wall of the feeding rack 3 towards the machine base 1. This effectively reduces the probability of material jamming, ensuring that the material can be smoothly fed into the discharge hopper 2, thereby guaranteeing degreasing efficiency and ensuring continuous feeding. With the vibration of the feeding rack 3, fine debris carried in the material can be removed from the material through the chip discharge trough 30, thus improving the cleanliness of the material.

[0038] As the hopper 2 gradually descends under the synchronous drive of the chains 10 on both sides, it pushes the pressure plate 6 downwards. At this time, the tilting frame 5, pulled by the pressure plate 6, overcomes the torque of the return torsion spring 50 and gradually tilts towards the hopper 2 until it reaches a horizontal position. Material can then fall from the open feed rack 3 outlet onto the tilting frame 5 and finally into the hopper 2, thus completing the automatic feeding process. As the hopper 2 gradually rises under the synchronous drive of the chains 10 on both sides, the tilting frame 5 gradually rotates back to its original position under the return force of the return torsion spring 50 until the feed rack 3 outlet closes again. The entire feeding process is completed automatically, effectively preventing material jamming.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
