[0015] The present invention provides a device and method for producing nylon staple fibers for nonwoven fabrics, which have the following beneficial effects: (1) In the present invention, after the inclined plate contacts the guide plate, the gap between the inclined plate and the guide plate is reduced, so that the raw materials cannot continue to flow to the bottom through the originally set gap. When the raw materials are too much, the raw materials cannot be continuously transported. Excessive accumulation of raw materials will prevent the raw materials from being fully squeezed due to excessive input of raw materials during subsequent shaping, resulting in shaping failure, and preventing the waste of raw materials. After the inclined plate rotates, the device returns to the original setting, so that the feeding can be automatically controlled according to the degree of raw material accumulation in real time, without manual operation, reducing labor input and increasing precision during operation.

[0016] (2) This invention drives the raw material to move toward the conveying plate after it is squeezed by the rotation of rollers one and two, and stretches the cooled raw material to improve its strength and uniformity, which is convenient for subsequent processing. The movement of the pressing plate presses the button at the bottom layer, causing the output end of the servo motor to stop rotating. The pressing plate is driven to press different buttons according to the remaining amount of raw material, and the device can be automatically shut down after the raw material processing is completed, thereby reducing energy loss.

[0017] (3) The invention drives the positioning plate to move back and forth through the reciprocating movement of the telescopic rod, and the reciprocating movement of the positioning plate pushes the processed raw materials to prevent the raw materials from being squeezed and extending to both sides so as to be unable to move normally toward the conveying plate, thereby improving the stability of the device during operation. When the arc rod cannot rotate toward the bottom, the positioning plate is driven to move toward the top through its own arc design, so that when the positioning plate moves away from the raw materials, it is lifted toward the top and does not contact the raw materials, thereby preventing the positioning plate from sticking to the raw materials after contacting the raw materials, thereby damaging the raw materials, thereby improving the practicality of the device.

After the inclined plate 54 contacts the guide plate 53, the gap between the inclined plate 54 and the guide plate 53 is reduced, so that the raw materials cannot pass through the originally set gap The gap continues to flow to the bottom, so that when the raw materials are accumulated too much, the raw materials cannot be continuously transported, to prevent the excessive accumulation of raw materials from causing the subsequent shaping of the raw materials to result in the inability to fully squeeze the raw materials due to excessive input of raw materials, resulting in shaping failure, to prevent the waste of raw materials.
