Description

Technical Field

[0001] The present invention relates to the field of transportation technology, and in particular to an automatic feeding device and a feeding process for recycled aluminum processing. Background Art

[0002] The output of recycled aluminum alloy waste is very large at home and abroad. Recycled aluminum is an aluminum alloy or aluminum metal obtained by remelting and refining scrap aluminum and scrap aluminum alloy materials or aluminum-containing scrap. Before smelting scrap aluminum, various scrap aluminum parts need to be sorted or disassembled and cut into regular small blocks to separate iron and other non-ferrous metal parts, and then the aluminum blocks are processed. In the process of recycled aluminum processing, a reaction collector tank is needed to add aluminum blocks into the reaction collector tank for heating. During use, the aluminum blocks transported to a high place need to be loaded into the reaction collector tank at a low place. However, in the process of loading to a low place, some larger aluminum blocks will accelerate the slide due to the gravity of the aluminum blocks themselves, and easily hit the transport rollers and cause damage to them. At the same time, small impurities are easily attached to the aluminum blocks, which affects subsequent processing and needs to be filtered. However, after long-term filtration, the filter holes will be blocked over time, affecting the quality of the aluminum blocks. For this reason, we propose an automatic loading device and loading process for recycled aluminum processing. Summary of the invention

A first air hole is provided on the outer surface of the connecting plate near the bottom, a second air hole is provided on the outer surface of the rotating tube, and a third air hole is provided near the middle of the rotating tube. An arc-shaped baffle is fixedly connected to the surface of the sliding plate, and an air intake duct is provided on the outer surface of the connecting tube.

[0009] Preferably, the upper surface of the frame is rotatably connected to a positioning rod via a bearing, the outer surface of the positioning rod is fixedly connected to a third gear, the outer surface of the outer frame is fixedly connected to a ring gear, and the third gear is meshingly connected to the ring gear.

[0013] Preferably, an automatic feeding process for recycled aluminum processing comprises the following steps: S1: According to the transport height, rotate the outer frame to drive the internal transport rollers to move up and down. When the appropriate height is adjusted, stop rotating the outer frame.

[0014] S2: Place the aluminum block on the top transport roller, ventilate the inside of the air inlet pipe, and the gas enters the inside of the connecting pipe, causing the transport roller to rotate and transport the aluminum block on the surface.

[0015] S3: The surface of the transport roller is provided with filtering holes to filter the debris in the aluminum block.

At this time, the transport roller rotates under the force, and the clamping groove on the positioning ring pushes the clamping block to move inside the positioning groove. The first spring can buffer the impact force on the transport roller.

[0017] S5: The gas is discharged from the third air hole on the connecting pipe, blowing the impurities entering the conveying roller downwards. The impurities pass through the conveying roller and fall into the sliding frame, and slide to the bottom of the device.

[0018] Compared with the prior art, the advantages and positive effects of the present invention are: 1. The present invention proposes an automatic feeding device and a feeding process for recycled aluminum processing, which ventilates the inside of the air inlet pipe through an external air source, and the gas enters the inside of the connecting pipe and blows the spiral blade to rotate, thereby driving the rotating pipe to rotate. The rotating pipe can drive the internal gear to rotate through the cooperation of the first gear and the second gear. The internal gear drives the surface block to rotate through the rotating disk, and the block drives the transport roller to rotate by pushing the positioning ring. At this time, the aluminum block on the surface can be transported downward. During transportation, the filter holes arranged on the surface of the transport roller can filter the debris in the aluminum block, effectively improving the purity and uniformity of the aluminum, and at the same time improving the product quality.

[0019] 2. The present invention proposes an automatic feeding device and feeding process for recycled aluminum processing, which rotates a spiral blade by blowing it through an external air source, thereby driving the rotating tube to rotate. During the process, the eccentric block on the surface of the rotating tube rotates, which can drive the connecting tube to become eccentric. The connecting tube drives the support frame on the surface to move up and down, and the support frame squeezes the upper and lower springs back and forth, so that the connecting tube can drive the transport roller to vibrate up and down, which can effectively improve the filtering effect, ensure the smoothness of the filter holes, avoid clogging of the filter holes, affect the filtering effect, and cause the aluminum block to be of low quality.

[0020] 3. The present invention proposes an automatic feeding device and a feeding process for recycled aluminum processing. When the transport roller drives the aluminum blocks on the surface to move, some heavier aluminum blocks will accelerate due to their own weight. When the moving speed is too fast, the aluminum blocks will hit the transport roller. At this time, the transport roller is forced to rotate faster. The rotation speed of the transport roller is greater than that of the rotating tube. Relative rotation occurs between the transport roller and the rotating tube. At the same time, the positioning ring inside the transport roller rotates, and the card groove on the positioning ring pushes the card block to move toward the inside of the positioning groove. The first spring can buffer the impact force on the transport roller, effectively absorb the impact energy generated by the aluminum block colliding with the transport roller, reduce the vibration amplitude of the transport roller itself, and thus increase the service life of the transport roller.

[0021] 4. The present invention proposes an automatic feeding device and a feeding process for recycled aluminum processing, which rotates a spiral blade by blowing it with an external air source, thereby driving the rotating tube to rotate. During this process, the gas enters the other side of the connecting tube from the first air hole on the connecting plate, and enters the interior of the connecting tube from the second air hole on the rotating tube, and is discharged from the third air hole near the middle of the connecting tube. At this time, impurities entering the transport roller can be blown downward, which can effectively accelerate the efficiency of impurity discharge in the transport roller, and the airflow blown downward can pass through the transport roller through the arc baffle to transport the impurities that fall onto the sliding frame downward, thereby improving work efficiency.

[0022] 5. The present invention proposes an automatic loading device and loading process for recycled aluminum processing. According to the stacking height of the aluminum blocks, the positioning rod is rotated, and the third gear cooperates with the ring gear to drive the outer frame to rotate. At this time, the second rectangular rod slides inside the second limit groove, and at the same time, the first rectangular rod slides inside the first limit groove, which can drive the internal transport roller up and down. After adjusting to the appropriate height, the rotation of the outer frame is stopped, and the aluminum blocks are placed on the top transport roller for loading. Aluminum blocks of different heights can be transported, effectively improving the practicality of the device. BRIEF DESCRIPTION OF THE DRAWINGS

When the height is adjusted to a suitable height, the outer frame 8 is stopped from rotating.

[0036] S2: Place the aluminum block on the top transport roller 201, ventilate the inside of the air inlet pipe, and let the gas enter the inside of the connecting pipe 10, so that the transport roller 201 rotates to transport the aluminum block on the surface.

[0037] S3: The surface of the transport roller 201 is provided with filtering holes to filter the debris in the aluminum block. At the same time, the eccentric block 13 on the surface of the rotating tube 202 rotates during the rotation process, driving the transport roller 201 to vibrate up and down, thereby improving the filtering effect.
