Description

Technical Field

[0001] This utility model belongs to the technical field of chain link processing equipment, and relates to a vibratory feeder. Background Technology

[0002] A vibratory feeder is a device used for conveying materials. It consists of a hopper and a spiral feeding track installed on the inner wall of the hopper. A pulse electromagnet sits beneath the hopper, causing it to vibrate vertically. The parts inside the hopper are propelled upwards along the track by this vibration and arranged accordingly. Its purpose is to automatically and accurately transport disordered workpieces to the next processing step through vibration, ensuring an orderly and precise arrangement.

[0003] Feeding tracks are generally made of steel bars welded to the inner wall of the hopper. In actual use, it is found that when the vibratory feeder is conveying chain pieces, because the width of the steel bars is greater than the thickness of the chain pieces, adjacent chain pieces will overlap during vibration as the chain pieces climb along the track. The width of the steel bars can support two overlapping chain pieces, which will affect the subsequent conveying and processing of the chain pieces. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems existing in the conveying process of existing chain links by proposing a vibratory feeder that can cause the outer chain link of two stacked chain links inside the track to fall off.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A vibratory feeder includes a base and a hopper disposed on the base. The inner wall of the hopper is provided with a feeding track, which is spirally wrapped around the inner wall of the hopper. The feeding track is characterized in that it is divided into a conveying section and a discharge section along the conveying path, and the width of the feeding track in the discharge section is only able to support a single chain link.

[0007] In one of the vibratory feeders described above, the feeding track is made of steel bars welded to the inner wall of the hopper.

[0008] In one type of vibratory feeder described above, the width of the steel strip on the dropping section is smaller than the width of the steel strip on the conveying section.

[0009] In one of the above-mentioned vibratory feeders, the feeding track has a supporting surface and an abutting surface for supporting the chain links. The supporting surface is disposed on a steel bar and abuts against the bottom surface of the chain links. The abutting surface is disposed on the inner wall of the hopper and abuts against the back surface of the chain links.

[0010] In the aforementioned vibratory feeder, a notch is provided on the steel bar of the material drop section. The notch extends along the length of the material drop section so that the bottom surface of the chain link, the inner wall of the hopper, and the steel bar form an overhead space. A portion of the bottom surface of the chain link entering the material drop section is located above the overhead space, while the remaining portion rests against the steel bar.

[0011] In the aforementioned vibratory feeder, a guide plate is also provided on the material dropping section. The guide plate is located on the outside of the steel bar, with one end of the guide plate flush with the support surface and the other end extending in the direction of chain movement and lower than the support surface.

[0012] In the aforementioned vibratory feeder, a guide ramp is provided on the conveying section, and the guide ramp is located at the outlet of the dropping section, with the outer end of the guide ramp flush with the outer surface of the steel bar on the dropping section.

[0013] In the aforementioned vibratory feeder, a baffle is also provided on the material dropping section. The baffle is welded and fixed to the inner wall of the hopper. The baffle is located directly above the steel bar. The gap between the baffle and the steel bar is adapted to the height of the chain link. When the chain link on the material dropping section falls, it can be blocked by the baffle to prevent the chain from falling off the feeding track.

[0014] In the aforementioned vibratory feeder, the gap between the baffle and the chain is 30-50 mils.

[0015] In one type of vibratory feeder described above, the total width of the steel bars on the dropping section is matched with the thickness of a single chain link.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The material drop section reduces the width of the steel bar so that it can only carry a single chain link. When two stacked chain links pass through the material drop section, the outer chain link will slide off due to vibration.

[0018] 2. To prevent the inner chain links from sticking together and being pulled down when the outer chain links fall off, a guide plate is designed to gradually separate the outer chain links from the inner chain links along the guide plate.

[0019] 3. When entering the conveyor section, the chain on the guide plate will move forward along the guide slope on the steel bar of the conveyor section, so that the chain on the guide plate will gradually separate from the chain on the inner side until the two stacked chain plates are completely separated.

[0020] 4. Make notches in the steel bars of the dropping section so that the bottom part of the chain links entering the dropping section is suspended in the air, reducing the contact area between the chain links and the supporting surface. The purpose is to increase the deviation of the center of gravity projection of the chain links from the contact range. Therefore, gravity will generate a torque that causes the chain links to rotate around the contact surface, causing the chain links to tend to tilt towards the inner wall of the hopper. The ultimate goal is to prevent the inner chain links from falling off the steel bars of the dropping section. Attached Figure Description
