Description

Technical Field

[0001] This utility model relates to the field of spinning machinery technology, and in particular to a self-cleaning polyethylene fiber spinneret device. Background Technology

[0002] A spinning machine is a machine that forms filaments from a polymer solution or melt. Depending on the spinning method, spinning machines are classified into three types: wet spinning machines, melt spinning machines, and dry spinning machines. Electrospinning technology utilizes a non-Newtonian fluid polymer solution under a high-voltage electric field to overcome surface tension and viscoelastic forces, resulting in nano- to submicron-sized fibers. The polyethylene fiber spinneret is a key component in the spinning process, made of high-quality, high-temperature resistant, and wear-resistant materials, and precision-machined to form a specific microporous structure. During operation, the high-temperature molten polyethylene is extruded through the spinneret orifice and solidifies into filaments under the action of a cooling medium. The orifice shape, diameter, and distribution precision directly affect the fineness, strength, and uniformity of the fibers, and are crucial for improving the quality and production efficiency of polyethylene fibers. However, because the surface of this device is prone to dust accumulation, it requires frequent cleaning, which affects the spinning process and results in poor reliability.

[0003] Announcement No. CN222499482U discloses a spinning head device for a spinning machine, which can quickly and automatically clean the spinning head during the spinning interval, maintain surface cleanliness, ensure spinning effect, and improve reliability. It includes a spinning head mechanism and a spinning head. The output end of the spinning head mechanism is connected to the inner end of the spinning head. It also includes an inner ring, balls, an outer ring, an annular brush, a reducer connecting frame, a reducer, a motor, a driving bevel gear, and a bevel gear ring. The outer end of the spinning head mechanism is connected to the outer end of the outer ring via a moving mechanism. The inner side of the outer ring is rotatably connected to the outer side of the inner ring via multiple sets of rolling balls. The front end of the inner ring is connected to the rear end of the bevel gear ring. The middle of the top of the outer ring is connected to the rear side of the reducer via the reducer connecting frame. The input end of the reducer is connected to the output end of the motor. The output end of the reducer is connected to the middle of the top of the driving bevel gear. The driving bevel gear and the bevel gear ring are in movable meshing.

[0004] The aforementioned device cleans dust from the outer wall of the spinneret using a rotating brush. However, dust accumulates on the brush, and when the spinning mechanism of the spinning machine is operating, the dust escaping from the brush affects the spinning effect. Therefore, there is a need for a self-cleaning polyethylene fiber spinneret device. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defect of existing technology where dust accumulates on the brush and affects the spinning effect when the spinning mechanism of the spinning machine is working. This utility model proposes a self-cleaning polyethylene fiber spinneret device.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a self-cleaning polyethylene fiber spinneret device, comprising: a spinning machine spinneret body and a spinneret, wherein the output end of the spinning machine spinneret body is connected to the end of the spinneret, an mounting plate is provided below the spinning machine spinneret body and the spinneret, the spinning machine spinneret body is fixedly mounted on the mounting plate, a dust extraction component is provided below the spinneret, and a cleaning component is provided above the mounting plate;

The air in the dust extraction pipe enters the dust collection box through a pair of connecting pipes. As the air flows, dust enters the dust collection box through the first through hole, the second through hole, and the pair of connecting pipes.

[0010] Preferably, the cross-section of the barrier strip is spindle-shaped, the inner diameter of the dust extraction pipe gradually decreases from the end near the spinning machine spinneret to the end away from the spinning machine spinneret, and several fixed comb teeth are equidistantly and symmetrically fixed on both sides of the barrier strip.

[0011] The spindle-shaped baffle strips help to block dust from the cleaning brush, the fixed comb teeth help to comb the cleaning brush, and the suction pipe with a gradually decreasing inner diameter ensures that the suction power of the first and second through holes at different positions is roughly the same.

[0012] Preferably, the cleaning assembly includes a mounting ring, which is sleeved on the outside of the spinneret and rotatably mounted between a pair of fixed mounting brackets. The pair of fixed mounting brackets are fixedly mounted on the top surface of the mounting plate. An inclined mounting strip is provided inside the mounting ring.

[0013] Preferably, a fixed worm gear is coaxially fixedly sleeved on the outer wall of the mounting ring, and a forward and reverse motor is fixedly installed on the top surface of the mounting plate. The output shaft of the forward and reverse motor is coaxially fixedly connected to a rotating worm, and the fixed worm gear and the rotating worm cooperate with each other.

[0014] Preferably, the mounting bracket is U-shaped, and the spinneret is located in the center of the mounting bracket.

[0015] Start the forward and reverse motor, which drives the rotating worm to rotate. The fixed worm wheel, which works in tandem with the rotating worm, rotates synchronously. The fixed worm wheel drives the mounting ring to rotate, and the mounting ring, through the connecting block and mounting strip, drives the cleaning brush to rotate. The cleaning brush cleans the dust from the outer wall of the spinneret.

[0016] Compared with the prior art, the beneficial effects of this utility model include: by setting up a dust extraction component, the air extraction machine works, and outside air enters the dust extraction pipe through the first through hole and the second through hole. The air in the dust extraction pipe enters the dust collection box through a pair of connecting pipes. As the air flows, dust enters the dust collection box through the first through hole, the second through hole and the pair of connecting pipes. The fixed comb teeth facilitate the combing of the cleaning brush. The dust extraction pipe with a gradually decreasing inner diameter makes the suction power of the first through hole and the second through hole at different positions approximately the same, avoiding the dust escaping from the cleaning brush from affecting the filament spinning effect.
