Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of material sorting, and particularly relates to an air blowing structure. Background Art
[0002] Material sorting is a fundamental and critical process in industrial production and material handling. Traditional material sorting technologies typically rely on physical properties such as size, weight, density, color, or shape to separate different materials. These methods include, but are not limited to, manual sorting, screening, flotation, magnetic separation, and airflow separation.
[0003] Air-blowing roller sorting technology is widely used, particularly in automated production lines, due to its high efficiency and low cost. Air-blowing sorters use nozzles positioned above or to the side of the material, harnessing the force of airflow to separate the materials. This technology is particularly effective when handling lightweight, fine materials that are easily blown by the wind.
[0004] After searching, the prior art, Chinese patent application number: CN201820678755.0, discloses a material sorting device, including a guide mechanism and an air blowing mechanism. The guide mechanism includes a guide plate, with baffles provided on both sides of the guide plate, a guide channel formed between the two guide bars, a feed port connected to the guide channel provided at the front end of the guide plate, and a discharge port connected to the guide channel provided at the rear end of the guide plate. One of the baffles is provided with a discharge port connected to the guide channel, and the other baffle is provided with a first air blowing port corresponding to the discharge port. A convex strip is provided in the middle of the guide plate, and the convex strip is arranged along the length of the guide plate, the convex strip is located in the guide channel, and the convex strip is located between the discharge port and the first air blowing port. By utilizing the coordination of the first air blowing port, the guide channel, the convex strip, and the discharge port, nuts without welds can be automatically sorted. This simple structure can improve production efficiency and reduce labor costs.
[0005] However, existing air-blowing rolling sorting technology has several limitations. First, in an upward-blowing configuration, after the material is blown vertically upward, the success rate of material sorting cannot reach 100% due to uneven airflow distribution and the influence of the material's own weight. Second, a side-blowing configuration may not be able to effectively handle special materials that require precise control of airflow direction and force. This results in a low sorting success rate and is unable to meet the precise sorting requirements for special materials. Utility Model Content
[0006] The purpose of the utility model is to provide an air blowing structure, which improves the success rate of material sorting by optimizing the angle and position of the nozzle, so as to solve the problems raised in the above background technology.
[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: an air blowing structure, comprising a frame, a transmission component for transmitting materials being installed on the frame, an air blowing component for sorting materials being installed on the frame, and a collection component for collecting materials being installed on the frame;
[0008] The blowing assembly includes a nozzle mechanism for sorting items, and the blowing assembly also includes an air supply mechanism for supplying air to the nozzle mechanism. The nozzle mechanism and the air supply mechanism are both installed on a frame, and the nozzle mechanism is located between the air supply mechanism and the material receiving assembly.
[0009] Furthermore, the nozzle mechanism includes a cantilever frame, which is mounted on the frame, and a nozzle block is mounted on one end of the cantilever frame.
[0010] Furthermore, multiple groups of nozzles and air pipes are installed on the nozzle block, and the ends of the multiple groups of air pipes away from the nozzle block are installed on the air supply mechanism. The angles of the multiple groups of nozzles are obliquely upward, and the nozzles are tilted to achieve the best blowing effect for dropping objects.
[0011] Furthermore, one end of the cantilever frame is an arc-shaped structure, and the other end of the cantilever frame is a straight plate.
[0012] Furthermore, the air supply mechanism includes a valve plate, which is installed on a frame. Multiple groups of solenoid valves are installed on the valve plate. The multiple groups of solenoid valves are respectively installed at one end of the multiple groups of air pipes away from the nozzle block. The control of the multiple groups of solenoid valves enables the separate operation of the multiple groups of air pipes, thereby performing sorting operations on the materials.
[0013] Furthermore, the transmission component includes a sprocket and a rolling conveyor bead chain. A sprocket shaft is installed on the sprocket, and the sprocket shaft is rotatably connected to the frame. The rolling conveyor bead chain is transmission-connected to the sprocket. The sprocket can drive the transportation of materials, and under the action of the nozzle, the items can be sorted during transportation.
[0014] Furthermore, the collection component includes a collection bucket, which is installed on the frame and arranged outside the blowing direction of the nozzle.
