Description

Technical Field

[0001] The utility model relates to the technical field of metal waste feeding and packing, in particular to a double-screw feeding device. Background Art

[0002] During the machining production process, a large amount of metal waste will be generated. For example, iron wire, aluminum wire, copper wire, iron filings, aluminum filings, and copper filings generated during the machining of workpieces by lathes, drilling machines, CNC machining centers, sawing machines, planing machines, etc. If not processed in time, it will cause environmental pollution and resource waste.

[0003] In daily production, the above-mentioned metal waste will be collected for recycling. However, due to the disorder of the metal waste, it is inconvenient to pack and transport directly when recycled. Therefore, the metal waste needs to be processed first. The double-screw feeding devices adopted in the prior art all use two mutually parallel feeding augers. In this way, when encountering long filamentous waste put into the device, the waste is prone to form a mass, resulting in material jamming, and it is impossible to normally transport the waste to the next process for packing. This requires adding a shredder before the conveying device to break the long filamentous iron filings, aluminum filings, and copper filings before conveying, increasing the equipment cost and affecting the work efficiency.

[0032] Embodiment 1:

[0033] Please refer to Figure 1-2 , a double-auger feeding device, including a silo main body 1, characterized in that: a feeding port 101 is opened on the upper surface of the silo main body 1, one end of the lower transverse side surface of the silo main body 1 is provided with a first motor flange 102, a discharge port 103 is opened at the other end of the lower transverse side surface of the silo main body 1, one end of the lower longitudinal side surface of the silo main body 1 is provided with a second motor flange 104, and the other end of the lower longitudinal side surface of the silo main body 1 is provided with a first connection flange 105; a first power mechanism 2 is installed on the first motor flange 102, the power output end of the first power mechanism 2 is connected to a first feeding auger mechanism 3, and the other end of the first feeding auger mechanism 3 extends to the discharge port 103; a second power mechanism 4 is installed on the second motor flange 104, the power output end of the second power mechanism 4 is connected to a second feeding auger mechanism 5, a bearing mechanism 6 is installed on the first connection flange 105, and the other end of the second feeding auger mechanism 5 extends and is installed into the bearing mechanism 6; the second feeding auger mechanism 5 is located above the first feeding auger mechanism 3, and the second feeding auger mechanism 5 and the first feeding auger mechanism 3 are perpendicular to each other in a cross state.

[0034] In the above embodiments, the first power mechanism 2 includes a first speed reducer 201 installed on the first motor flange 102. The input end of the first speed reducer 201 is connected to a vertically arranged first motor 202, and the output end of the first speed reducer 201 is connected to one end of the first feeding auger mechanism 3. The second power mechanism 4 includes a second speed reducer 401 installed on the second motor flange 104.

The bearing mechanism 6 includes a bearing cover flange 601 installed on the first connection flange 105. A flange bearing 602 is installed on the bearing cover flange 601, and the flange bearing 602 is installed on the other end of the second feeding auger mechanism 5.

[0035] In the above embodiments, the first feeding auger mechanism 3 includes a first rotating rod 301 installed at the power output end of the first power mechanism 2. A plurality of first spiral blades 302 are fixedly arranged on the outer circumferential surface of the first rotating rod 301. The number of the first spiral blades 302 is preferably five; the second feeding auger mechanism 5 includes a second rotating rod 501 installed at the power output end of the second power mechanism 4.

As a reserved solution, a material auger mechanism or a stirring mechanism is only needed to be added between the third motor flange 106 and the second connecting flange 107 in special cases.

[0043] In summary, for this double-auger feeding device, by designing the two feeding auger mechanisms into a cross-shaped structure perpendicular to each other, and setting the sizes and quantities of the spiral blades on the two feeding auger mechanisms to be different, the transportation of metal waste is made more smooth, secondary processing equipment is reduced, the transportation efficiency of metal waste is improved, and the production cost is reduced.
