Description

Technical Field

[0001] This utility model relates to the field of screw extruder technology, specifically a screw extruder for fiber production. Background Technology

[0002] The screw extruder used for fiber production is the core equipment for the production of synthetic fibers (such as polyester and nylon). It mainly undertakes the tasks of melting, conveying and homogenizing polymer raw materials, and is a key hub connecting raw materials and spinning.

[0003] Chinese patented invention CN214491538U discloses a twin-screw extruder. The technical solution is as follows: a twin-screw extruder includes a twin-screw extruder body, a receiving device disposed at the discharge end of the twin-screw extruder body, and a guiding device disposed at the discharge end of the receiving device. The receiving device includes a conveyor belt disposed at the discharge end of the twin-screw extruder body and a driving assembly for driving the conveyor belt. The conveyor belt includes several connecting belts, and several grooves are formed on the connecting belts, the grooves corresponding to the discharge port of the twin-screw extruder body.

[0004] The screw extruder has an open top for easy filling of the feed hopper, but this design makes it easy for dust to fall inside the hopper. On the one hand, the dust mixed with the material is not conducive to fiber production, and on the other hand, the operator has to constantly observe the material in the feed hopper to add material in time, which increases the operator's workload. Therefore, a screw extruder for fiber production is proposed. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a screw extruder for fiber production, comprising a base, a screw extruder body mounted on the front side of the upper surface of the base, a feed box provided on the screw extruder body, a feed pipe connected to the rear surface of the feed box, a support fixedly connected to the rear side of the upper surface of the base, a motor mounted on the upper surface of the support, a rotating shaft fixedly connected to one end of the output shaft of the motor, the rotating shaft extending into the feed pipe, an auger fixedly connected to the outer wall of the rotating shaft, a hopper connected to the rear side of the upper surface of the feed pipe, a feeding hopper connected to the rear side of the upper surface of the hopper, a cover plate hinged to the right side of the upper surface of the feeding hopper, a fixed seat fixedly connected to the left side of the upper surface of the base, a control panel, a flashing light and a buzzer respectively mounted on the upper surface of the fixed seat, a level gauge mounted on the upper surface of the hopper, the probe end of the level gauge extending into the hopper.

[0007] As a further preferred embodiment of this technical solution: the electrical output terminal of the level gauge is electrically connected to the electrical input terminal of the control panel via a wire, and the electrical output terminal of the control panel is electrically connected to the electrical input terminals of the motor, the flashing light, and the buzzer via wires respectively.

[0008] As a further preferred embodiment of this technical solution: four fixing blocks are symmetrically fixedly connected to the outer side wall of the hopper, and a support leg is fixedly connected to the lower surface of the fixing block, with the bottom of the support leg fixedly connected to the upper surface of the base.

[0009] As a further preferred embodiment of this technical solution: a through groove is provided on the front surface of the hopper, and a transparent plate is fixedly connected to the inner side wall of the through groove.

[0010] As a further preferred embodiment of this technical solution: a handle is fixedly connected to the left side of the upper surface of the cover plate.

[0011] As a further preferred embodiment of this technical solution: universal wheels are evenly installed on the lower surface of the base, and a push handle is fixedly connected to the upper part of the right side wall of the base.

[0012] As a further preferred embodiment of this technical solution: a support rod is uniformly and fixedly connected between the lower surface of the feed pipe and the upper surface of the base.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention allows for automated, enclosed feeding of the screw extruder by opening the cover plate and pouring the material into the hopper. After completion, the cover plate is closed, and the material falls into the hopper and enters the feed pipe. The motor drives the rotating shaft and auger to rotate, and the auger's conveying force sends the material into the feed box. This achieves closed, automated feeding of the screw extruder, preventing dust from falling in and affecting fiber quality. Furthermore, a level gauge monitors the remaining material in the hopper. When the remaining material is too low, a flashing light and a buzzer sound an alarm to remind the operator to refill the hopper in time. This eliminates the need for operators to constantly monitor the material in the hopper, reducing their workload and bringing convenience to the use of the screw extruder.
