Description

Technical Field

[0001] The utility model belongs to the field of spinning material feeding, in particular to a feeding switching system. Background Art

[0002] Vacuum suction and compressed air feeding are two common methods of feeding materials into the textile and chemical fiber industry's batching systems. Specifically, vacuum suction uses a vacuum motor to create negative pressure in the feeding barrel, drawing the raw materials into the batching system through the feeding pipe; compressed air feeding uses compressed air to create positive pressure in the feeding pipe, feeding the raw materials into the batching system. Because different raw materials require different feeding methods, it is crucial to be able to produce products with different raw materials using both feeding methods on the same spinning equipment.

[0004] The first discharge port of the first raw material feeding assembly and the second discharge port of the second raw material feeding assembly are connected to the feed port of the batching device;

[0005] The first raw material loading assembly includes a drying device and a first raw material storage barrel. The first raw material is dried by the drying device and placed in the first raw material storage barrel. The outlet of the first raw material storage barrel forms a first discharge port, and the first discharge port is provided with an electric valve.

[0006] The second raw material feeding assembly includes a negative pressure fan, a second raw material storage barrel, and a negative pressure suction pipe connecting a second discharge port of the second raw material storage barrel and a feed port of the batching device.

[0007] Through the above technical solution, the batching device of the present invention is an existing batching device, and different raw materials enter the screw production through the batching system. The batching device is provided with an output port, that is, a screw conveyor can be configured at the output port of the batching device.

[0008] The utility model has two raw material feeding components at the same time to realize the batching and feeding of raw materials.

[0009] The outlet of the drying device is connected to the first raw material storage barrel through a positive pressure delivery pipe. When the second raw material feeding assembly is feeding, the electric valve is closed and the negative pressure fan is turned on.

[0010] When the first raw material loading assembly is loading, the negative pressure fan is turned off and the electric valve is opened. The first raw material can be polyester, and the second raw material can be nylon. After drying, the polyester enters the storage barrel through the positive pressure conveying pipe and then enters the batching device. The other raw material, nylon, enters the batching device through the negative pressure suction pipe.

[0011] Among them, the switch of the electric valve is the first switch, the switch of the negative pressure fan is the second switch, and a control switch is also included. The control switch controls at most one of the first switch and the second switch to be opened.

[0028] When the first raw material loading assembly 2 is loading, the negative pressure blower 301 is closed and the electric valve 204 is opened. The first raw material can be polyester, and the second raw material can be nylon. After drying, the polyester enters the storage barrel through the positive pressure delivery pipe and then enters the batching device 1.
