Abstract
Description
Technical Field
[0001] This utility model relates to the field of material conveying equipment technology, specifically to a material flow control device for a vibrating feeder. Background Technology
[0002] Vibrating feeders, also known as vibrating feeders, play a vital role in industrial production. Their efficient and stable operation is crucial for the smooth running of the entire production line. In the production process, vibrating feeders are used to uniformly, continuously, or quantitatively feed large pieces, granular, and powdery materials from storage silos or other storage equipment to receiving equipment. They are suitable for automatic batching, quantitative packaging, and automated control operations. In sand and gravel production lines, they can continuously and uniformly feed crushing machinery and perform coarse screening of materials. They are widely used in crushing and screening equipment in industries such as metallurgy, coal mining, mineral processing, building materials, chemicals, and abrasives.
[0003] A vibrating feeder consists of a trough, vibrator, spring support, transmission device, and vibrating motor. Its working principle is as follows: the trough is driven by a vibrator composed of two eccentric shafts and gears, which generates a vibration source. The motor then drives a V-belt to rotate the main shaft and gears. The main shaft and the driven shaft rotate in opposite directions at the same time, causing the trough to vibrate. This causes the material to flow continuously, making a continuous throwing and falling motion, thereby achieving the purpose of conveying the material.
[0004] However, in actual use, vibrating feeders may encounter problems such as material slippage and spillage, which can affect the uniform supply of materials and production efficiency. Under normal circumstances, vibrating feeders rely on the vibration force generated by a vibrating motor or exciter to move materials at a certain speed and flow rate. However, when the feeder trough tilt angle is too large, the influence of gravity on the material movement exceeds the normal range, leading to material slippage. Therefore, to solve the above problems, this utility model provides a vibrating feeder material flow control device to solve the problem of material slippage and spillage when the vibrating feeder trough tilt angle is too large. Utility Model Content
[0005] The purpose of this utility model is to provide a material flow control device for a vibrating feeder to solve the problem of material slippage and spillage when the inclination angle of the vibrating feeder trough is too large.
[0006] To achieve the above objectives, the basic solution provided by this utility model is as follows: a material flow control device for a vibrating feeder, comprising a storage bin and a feeding trough, wherein the storage bin is located above the feeding trough, a gate slot and a cylinder are fixedly connected to one end of the storage bin, a gate is slidably connected to the gate slot, the gate and the telescopic end of the cylinder are fixedly connected, the gate is located directly above the discharge port of the feeding trough, a vibrator is provided on the feeding trough, a vibration motor is provided on the vibrator, a shock-absorbing spring is fixedly connected to the feeding trough, a spring support is fixedly connected to the other end of the shock-absorbing spring, and an adjustment mechanism is provided on the spring support.
[0007] The working principle of this utility model is as follows: When in use, first start the vibrating motor, then drop the material from the storage bin into the feeding trough. Under the action of the vibrator, the feeding trough vibrates, and the material is continuously thrown up and down in the feeding trough to complete the material transportation work. When it is necessary to turn off the vibrating feeder to stop conveying materials, first turn off the vibrating motor, then turn on the cylinder. The cylinder drives the gate to move downward to close the discharge port.
[0008] The beneficial effects of this utility model are as follows: By adding a gate above the discharge port of the feeding trough, this utility model can achieve the effect of sealing the discharge port of the feeding trough. When the feeding trough is tilted at a large angle and the equipment is closed, this design can effectively prevent material slippage and spillage.
[0009] Option 2, a preferred embodiment of the basic option, includes a lifting lug and a support leg. The support leg has a cavity, which is nested with a spring support. Both the support leg and the spring support have a first through hole, and the support leg and the spring support are bolted together. The inclination angle of the feeding trough can be adjusted by adjusting the height of the support leg, thereby controlling the feeding amount.
[0010] Option 3, which is a preferred option of the basic option, has anti-slip ridges on the feeding trough; this can increase the residence time of the material in the feeding trough, prevent the material from accumulating, and play a role in uniform material distribution.
[0011] Option 4, a preferred option of the basic option, has a liner fixedly connected to the discharge end of the feeding trough. The discharge end of the feeding trough is provided with a through groove, and the through groove is provided with several second through holes. A bar is bolted to the through groove, and the bar fits in close to the liner. By adjusting the gap between the bars, it can accommodate materials of different specifications, and at the same time, it can evenly feed the material into the receiving system, preventing equipment failure caused by uneven feeding.
[0012] Option 5, which is a preferred option of the basic option, involves connecting the vibratory motor and the cylinder in series, with the vibratory motor powered on and connected to a PLC controller. The series connection of the cylinder and the vibratory motor can promptly close the gate to prevent material slippage and spillage. The PLC controller can also enable remote control for easy operation. Attached Figure Description

After adjusting to a suitable angle, insert the bolt into the first through hole 12 to fix the spring support 9 and the support leg 11. Then, according to the requirements, insert the bar 17 into the through groove 15 and align it with the second through hole 16. Then, insert the bolt into the second through hole 16 to fix it. Then, start the vibration motor 7 through the PLC controller. Then, the material falls from the storage bin 1 into the feeding trough 2. Under the action of the vibrator 6, the feeding trough 2 vibrates. The material is continuously thrown up and fell in the feeding trough 2 to complete the material transportation work. When it is necessary to turn off the vibrating feeder to stop transporting materials, first turn off the vibration motor 7 and at the same time, the cylinder 4 is opened. The cylinder 4 drives the gate 5 to move downward to close the discharge port.
