Description

Technical Field

[0001] The invention relates to the technical field of textiles, and in particular to a polyester fiber whitening spinning system. Background Art

[0002] Polyester fiber, commonly known as "polyester", is a synthetic fiber made from organic dibasic acids and diols through chemical polycondensation. It is a kind of polymer compound. Polyester fiber has excellent wrinkle resistance and shape retention. Clothes made from it are not easy to wrinkle during wearing and can maintain their original shape. Secondly, polyester fiber has high strength and elastic recovery ability, making the woven fabric strong and durable, and can quickly restore to its original shape. In addition, polyester fiber also has the characteristics of wear resistance and non-stick hair, making the fabric look neater.

[0003] In the prior art, in the production process of polyester fibers, it is necessary to use a spinning system to fix raw materials to make raw fiber yarns. The spinning system mainly consists of an extruder, a filter, a metering pump, a spinneret, a cooling assembly, an oiling assembly, and a winding assembly. To whiten the fibers, a whitening agent can be mixed into the raw materials when the raw materials are melted. In the spinning system, the filter mainly filters the raw materials after the melt state to screen out the internally doped solid impurities and the unbent molten solid raw materials, so as to improve the subsequent product quality. However, common filters cannot quickly discharge the raw materials during filtering, and too much impurity accumulation after filtration can easily cause clogging of the filter holes and affect subsequent filtration. How to invent a polyester fiber whitening spinning system to solve these problems has become an urgent problem to be solved by those skilled in the art. Summary of the invention

[0004] In order to make up for the above shortcomings, the present invention provides a polyester fiber whitening spinning system, which aims to solve the problem that the filter in the spinning system cannot quickly discharge the raw materials during filtering.

[0005] The present invention is achieved in that:

[0006] The present invention provides a polyester fiber whitening spinning system, comprising a lower barrel, a filter barrel and a fixing frame arranged on the lower barrel, a feeding pipe is installed inside the lower barrel near the upper end, two fixing plates are installed on the side wall of the feeding pipe, a guide rod is installed on one side of the fixing plate, and a limiting groove is provided on the inner wall of the lower barrel;

[0007] The upper end side wall of the filter cartridge is provided with a limiting ring rotatably connected to the inner wall of the limiting groove, and the side wall of the filter cartridge is provided with a first outer gear ring;

[0008] The fixing frame is installed on the upper outer wall of the lower barrel, a motor is installed above the fixing frame, a main shaft is installed on the outer wall of the fixing frame, a sliding groove is opened on the side wall of the main shaft, and a sliding gear is installed on the outer wall of the sliding groove.

[0009] Preferably, both ends of the guide rod are fixedly connected to the outer walls of the lower barrel and the fixed plate respectively, the upper end of the upper tube is connected to the discharge port of the extrudate, and the surfaces of the lower barrel and the filter barrel are coated with a self-lubricating coating.

[0010] Preferably, the feeding pipe is inserted into the interior of the filter cartridge, and a plurality of filter holes are provided on the side wall and the bottom of the filter cartridge.

[0011] Preferably, the output end of the motor is fixedly connected to one end of the main shaft, the outer wall of the main shaft is rotatably connected to the inner wall of the fixing frame, and the sliding gear is meshingly connected to the first outer gear ring.

[0012] By adopting the above technical scheme, before the molten raw material enters the spinning component, the raw material enters the feeding pipe through the extruder and enters the filter cylinder below. At this time, the motor is started to drive the main shaft to drive the filter cylinder to rotate, so that the molten raw material can be quickly thrown out through the filter holes opened in the side wall, thereby increasing the feeding speed. At the same time, the rotating filter cylinder will shake the impurities and solid raw materials remaining inside in a disorderly manner during the high-speed movement, causing their position to change continuously, effectively avoiding the problem that impurities and solid raw materials accumulate at the bottom and easily cause blockage of the filter holes after filtering the raw materials in a static state, thereby improving the filtering effect and the feeding speed. At the same time, the raw material thrown out of the filter cylinder enters the outer feeding cylinder, and flows downward along the side wall of the feeding cylinder under the action of gravity into the subsequent textile components.

[0013] Preferably, symmetrical electromagnets are installed on the side walls of the main shaft close to both ends of the slide groove, and a fixing ring is installed on the outer wall of the feeding tube. The inner wall of the fixing ring is slidably connected to the outer wall of the guide rod.

[0014] Preferably, a reciprocating screw rod is rotatably connected to an inner wall of one side of the fixing ring, a first gear is installed on the upper end of the reciprocating screw rod, and a second gear is installed on the other end of the reciprocating screw rod.

[0015] Preferably, the fixed ring is rotatably connected to a sleeve near the inner wall of the reciprocating screw, the side wall of the sleeve is fixedly connected to a fourth gear meshing with the first gear, the inner wall of the sleeve is slidably connected to a slide rod, the bottom end of the slide rod is rotatably connected to the inner wall of the discharge barrel, and the side wall of the slide rod is installed with a third gear meshing with the first outer gear ring.

[0016] Preferably, the outer wall of the filter cartridge is slidably connected to a mounting ring, the side wall of the mounting ring is provided with a mounting groove, one side of the mounting groove is provided with a driving groove, the inner wall of the mounting groove is rotatably connected to a rotating ring, and the outer side wall of the rotating ring is provided with a second outer gear ring meshing with a second gear.

[0017] Preferably, the inner wall of the driving groove and the outer wall of the second gear are rotatably connected, the outer wall of the reciprocating screw and the inner wall of the mounting ring are rotatably connected, the outer wall of the reciprocating screw and the inner wall of the discharge barrel are threadedly connected, and a cleaning frame is installed on the side wall of the inner wall of the rotating ring, and a plurality of bristles are installed on the side wall of the cleaning frame.

[0018] By adopting the above technical scheme, after screening and discharging the raw materials once, in order to prevent some impurities from accumulating in the holes of the filter cartridge and causing blockage to affect subsequent filtration, the electromagnet above the slide slot is closed and the electromagnet below is energized, so that the electromagnet below and the sliding gear are magnetically attracted, so that the sliding gear slides downward and disengages from the first outer gear ring on the outside, and the sliding gear re-engages with the third gear. At this time, starting the motor again will rotate the sleeve ring and the first gear, so that the reciprocating screw and the inner wall of the discharge barrel are driven to slide downward, and then the cleaning frame installed on the inner wall of the mounting ring cooperates with the bristles to move the filter cartridge up and down to clean, so that the bristles extend into the filter holes during the movement to clean the blocked impurities and solid raw materials, and avoid clogging of the filter holes, so as to ensure the subsequent filtration effect and the feeding speed of the raw materials. While the reciprocating screw rotates and moves downward, the second gear at its bottom and the second outer gear ring outside the rotating ring in the mounting ring rotate, and the rotating ring drives the cleaning frame and the bristles to rotate at the same time, so that the filter holes of the filter cartridge can be cleaned in multiple directions, thereby improving the cleaning effect.

[0019] The beneficial effects of the present invention are:

[0020] The filter drum is set to continuously rotate the raw materials inside, and the centrifugal force generated by the rotation throws the materials outward, thereby increasing the feeding speed. At the same time, the rotating filter drum will shake the impurities and solid raw materials remaining inside in a disorderly manner during the high-speed movement, causing their positions to change continuously, effectively avoiding the problem that the impurities and solid raw materials accumulate at the bottom and easily cause blockage of the filter holes after filtering the raw materials in a static state, thereby improving the filtering effect and the feeding speed. The electromagnet is set to cooperate with the sliding gear to keep the filter drum stationary after feeding, and at the same time, the mounting ring on its outer side slides up and down reciprocatingly, cooperating with the cleaning frame and bristles on the inner wall to clean the impurities and solid raw materials blocked in the filter holes, thereby avoiding blockage of the filter holes, thereby ensuring the subsequent filtering effect and the feeding speed of the raw materials. At the same time, the cleaning frame drives the bristles to rotate, and the filter holes of the filter drum can be cleaned in multiple directions, thereby improving the cleaning effect.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example, see Figure 1-Figure 10 A polyester fiber whitening spinning system comprises a lower barrel 1, a filter barrel 2 and a fixing frame 3 arranged on the lower barrel 1, a feeding pipe 11 is installed inside the lower barrel 1 near the upper end, two fixing plates 12 are installed on the side wall of the feeding pipe 11, a guide rod 13 is installed on one side of the fixing plate 12, and a limiting groove 14 is provided on the inner wall of the lower barrel 1;

[0038] It should be noted that before the molten raw material enters the spinning assembly, it is necessary to screen the impurities in the raw material and the solid raw material that is not completely melted through the filtering assembly. The raw material enters the feeding pipe 11 through the extruder and enters the filter cylinder 2 below. At this time, the motor 31 is started to drive the main shaft 32 to drive the outer sliding gear 34 to rotate. The sliding gear 34 engages with the first outer gear ring 22 on one side to drive the filter cylinder 2 to rotate. The rotating filter cylinder 2 makes the centrifugal force of the raw material inside increase the filtration speed, so that the molten raw material can be quickly thrown outward through the filter hole opened on the side wall, thereby increasing the feeding speed. At the same time, the rotating filter cylinder 2 will shake the impurities and solid raw materials remaining inside in a disordered manner during the high-speed movement, so that their positions are constantly changing, effectively avoiding the problem that the impurities and solid raw materials accumulate at the bottom after filtering the raw material in a static state, which is easy to cause clogging of the filter hole, thereby improving the filtering effect and increasing the feeding speed. At the same time, the raw material thrown out of the filter cylinder 2 enters the outer feeding cylinder 1, and flows downward along the side wall of the feeding cylinder 1 under the action of gravity into the subsequent textile components.

[0040] It should be noted that after screening and discharging the raw materials once, in order to prevent some impurities from accumulating in the holes of the filter barrel 2 and causing blockage and affecting subsequent filtration, the electromagnet 33 above the slide slot 321 is closed and the electromagnet 33 below is energized, so that the electromagnet 33 below and the sliding gear 34 are magnetically attracted, so that the sliding gear 34 slides downward and disengages from the first outer gear ring 22 on the outside, and at the same time, the sliding gear 34 re-engages with the third gear 421. At this time, starting the motor 31 again will cause the sliding gear 34 to engage with the third gear 421 to rotate, and the third gear 421 drives the sliding rod 42 and the outer ring 43 to rotate. When the ring 43 rotates, the fourth gear 431 on its outer side engages with the first gear 411 to rotate. During the rotation of the first gear 411, the reciprocating screw rod 41 and the inner wall of the discharge barrel 1 are transmitted to slide downward. The filter cartridge 2 is moved back and forth by the cleaning frame 54 and the brush 55, so that the brush 55 can extend into the filter hole during the movement to clean the blocked impurities and solid raw materials, thereby avoiding the blockage of the filter hole, thereby ensuring the subsequent filtering effect and the feeding speed of the raw materials. When the reciprocating screw rod 41 rotates and moves downward, the second gear 412 at its bottom end and the second outer gear ring 531 on the outer side of the rotating ring 53 in the mounting ring 5 rotate, and the rotating ring 53 drives the cleaning frame 54 and the brush 55 to rotate at the same time, so that the filter hole of the filter cartridge 2 can be cleaned in multiple directions, thereby improving the cleaning effect.

[0041] The working principle of this polyester fiber whitening spinning system:

[0042] Before the raw materials in a molten state enter the spinning assembly, it is necessary to screen the impurities in the raw materials and the solid raw materials that are not completely melted through the filtering assembly. The raw materials enter the feeding pipe 11 through the extruder and enter the filter cylinder 2 below. At this time, the motor 31 is started to drive the main shaft 32 to drive the outer sliding gear 34 to rotate. The sliding gear 34 engages with the first outer gear ring 22 on one side to drive the filter cylinder 2 to rotate. The rotating filter cylinder 2 makes the centrifugal force of the raw materials inside increase the filtering speed, so that the molten raw materials can be quickly thrown out to the outside through the filter holes opened on the side wall, thereby increasing the feeding speed. At the same time, the rotating filter cylinder 2 will shake the impurities and solid raw materials remaining inside in a disordered manner during the high-speed movement. , so that its position is constantly changing, effectively avoiding the problem that impurities and solid raw materials accumulate at the bottom and easily cause clogging of the filter holes after filtering the raw materials in a static state, improving the filtering effect while increasing the feeding speed, and at the same time, the raw materials thrown out of the filter cylinder 2 enter the outer feeding cylinder 1, and flow downward along the side wall of the feeding cylinder 1 under the action of gravity into the subsequent textile components. After the raw materials are screened and discharged once, in order to prevent some impurities from accumulating in the holes of the filter cylinder 2 and causing clogging and affecting subsequent filtration, the electromagnet 33 above the slide 321 is closed and the electromagnet 33 below is energized, so that the electromagnet 33 below and the sliding gear 34 are magnetically attracted, so that the sliding gear The third gear 421 drives the sliding rod 42 and the outer sleeve ring 43 to rotate. When the sleeve ring 43 rotates, the fourth gear 431 on the outer side engages with the first gear 411 to rotate. During the rotation of the first gear 411, the reciprocating screw rod 41 and the inner wall of the discharge barrel 1 are driven to slide downward, thereby driving the upper fixed ring 4 to move. When the fixed ring 4 slides down, it drives the sleeve ring 43 and the outer fourth gear 431 to move downward. The reciprocating screw 41 drives the mounting ring 5 on the outside of the filter cartridge 2 to rotate, and the cleaning frame 54 installed on the inner wall of the mounting ring 5 cooperates with the brush 55 to move the filter cartridge 2 up and down to clean it, so that the brush 55 extends into the filter hole during the movement to clean the blocked impurities and solid raw materials, thereby avoiding the blockage of the filter hole, thereby ensuring the subsequent filtering effect and the feeding speed of the raw materials. When the reciprocating screw 41 rotates and moves downward, the second gear 412 at its bottom end and the second outer gear ring 531 on the outside of the rotating ring 53 in the mounting ring 5 rotate, and the rotating ring 53 simultaneously drives the cleaning frame 54 and the brush 55 to rotate, thereby the filter holes of the filter cartridge 2 can be cleaned in multiple directions, thereby improving the cleaning effect.

[0043] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
