Description

Technical Field

[0001] The present invention relates to the technical field of equipment for manufacturing fibers, and particularly to an ultra-fine denier single-plate ring blowing 5D or 7D POY spinning line equipment. Background Art

[0002] Polyester POY filaments (pre-oriented filaments) are chemical fiber filaments with an orientation degree between that of unstretched filaments (UDY) and fully drawn filaments (FDY) obtained by high-speed spinning. Compared with unstretched filaments, they have a partially crystalline orientation structure, and their physical stability is significantly improved. They are mainly used as special raw materials for producing drawn textured yarns (DTY).

[0003] For example, an ultra-fine denier single-plate ring blowing 5D / 7D POY spinning line equipment disclosed in Chinese Patent CN111719189A still has some deficiencies in the production of polyester POY filaments:

[0004] At present, no relevant unloading equipment is provided inside the material tower in use. When discharging raw materials, the problem of material jamming is likely to occur;

[0005] At present, when drawing polyester POY filaments, the thickness of the filaments cannot be adjusted, which is inconvenient for producing polyester POY filaments of different specifications.

[0006] In view of the above problems, the present invention document proposes an ultra-fine denier single-plate ring blowing 5D or 7D POY spinning line equipment. Summary of the Invention

[0007] The present invention provides an ultra-fine denier single-plate ring blowing 5D or 7D POY spinning line equipment, which solves the problems of easy material jamming during the feeding process in the prior art and the inability to adjust the thickness of polyester POY filaments when drawing polyester POY filaments.

[0008] The present invention provides the following technical solutions:

[0009] An ultra-fine denier single-plate ring blowing 5D or 7D POY spinning line equipment, including a base, a material box and a processing box fixedly installed at the top. An outlet hole is opened at the bottom of the material box and is connected to a feeding pipe inside the processing box. It further includes:

[0010] A dispersion mechanism, including a driving shaft, a driven shaft and a first transmission belt surrounding both of them. The first transmission belt is hinged to an L-shaped rod through a connecting shaft. The L-shaped rod passes through a sliding hole at the top of the cleaning frame and drives the cleaning frame to reciprocate horizontally along the inner wall of the material box to loosen the material;

[0011] A drying mechanism, including a conveyor belt driven by a driving motor and an internal heating plate and a driving shaft. The driving shaft drives a driving gear through a worm and a worm gear, and drives the driving shaft of the dispersion mechanism to rotate synchronously;

[0012] The hot-melting mechanism includes a moving plate slidably connected inside a heating box. An electric heating rod is provided at the bottom of the moving plate, and the top is connected to the thread groove of a reciprocating lead screw through a transmission plate. The reciprocating lead screw is linked with a driving shaft through a second transmission belt, so that the moving plate heats the material horizontally and reciprocally.

[0013] The wire-forming mechanism includes a die tube connected to a delivery pump. A plurality of die holes with gradually increasing apertures are circumferentially and evenly distributed on the die tube, and the position of the die holes is adjusted by meshing a gear ring with a rack. The die holes are communicated with a wire-forming pipeline.

[0014] As a further improvement of the above technical solution:

[0015] The connecting shaft is fixed on the outer surface of the first transmission belt. The L-shaped rod is in clearance fit with the sliding hole of the connecting rod to form a crank-slider mechanism. The worm and the worm gear form a right-angle transmission pair. The tooth number ratio of the driving gear to the driven gear is 1:2 - 1:3. The transmission plate is in transmission connection with the reciprocating lead screw through a stop block. A wear-resistant coating (which can be a diamond-like coating) is provided on the contact surface between the stop block and the thread groove. The adjusting assembly of the die tube includes a plurality of card slots on a fixing plate. The positioning pin is elastically clamped with a moving ring through a tension spring to realize the positioning of the rack. The module of the gear ring and the rack is 0.5 - 1.0, and the stroke of the rack matches the pitch of the die holes. Heat dissipation fins are provided on the outer wall of the wire-forming pipeline. A scraper is provided on the inner wall of the heating box. The top of the scraper is in clearance fit with the edge of the conveyor belt to scrape off residual materials. A winding mechanism is further included. The winding mechanism includes a mounting shaft driven by a third transmission belt. A plurality of wire shafts that rotate synchronously are clamped on the mounting shaft. The wire shafts are connected to the mounting shaft through quick-release clamps. An anti-sticking coating (which can be PTFE or PFA) is coated on the surface of the wire shafts. The driving motor is a variable-frequency motor, and its rotation speed matches the transmission ratio of the third transmission belt, so that the linear velocity of the wire shafts remains constant.

[0016] It should be understood that the above general description and the following detailed description are only exemplary and cannot limit the present invention.

[0017] The beneficial effects are as follows: In the present invention, after the material is put into the feed box, the material can be conveyed to the conveyor belt through the feed pipe. By starting the driving motor to drive the driving shaft to rotate, under the driving action of the connecting assembly, the first transmission belt can be driven to move, so that the cleaning frame can move horizontally and reciprocally along the inner wall of the feed box, thereby being able to loosen the material in the feed box, prevent the material from condensing into a mass, and enable the material to be stably conveyed to the conveyor belt through the feed pipe, realizing stable feeding.

[0018] In the present invention, when the drive shaft rotates along with the output shaft of the drive motor, it can drive the conveyor belt to operate. Thus, after the material falls onto the conveyor belt along the feeding pipe, the material can be conveyed. And after the heating plate is electrified, it can generate heat, thereby heating the conveyor belt. Therefore, the material falling on the conveyor belt can be preheated, and at the same time, the moisture on the material can be removed. And the preheated material can be conveyed into the hot melting mechanism under the conveyance of the conveyor belt, and the material can be preheated while being conveyed. Thus, when the hot melting mechanism is used to hot melt the material, the hot melting efficiency can be improved;

[0019] In the present invention, after the reciprocating assembly receives the driving force of the drive shaft, it can operate, thereby providing power to the moving plate, causing the moving plate to perform a horizontal reciprocating motion in the heating box, and then driving a plurality of electric heating rods to perform a horizontal reciprocating motion, so as to facilitate the hot melting of the material falling into the heating box, making the material in a molten state. The material in the molten state has good fluidity and can be easily drawn out for spinning;

[0020] In the present invention, by starting the delivery pump, the material in the molten state in the heating box can be pumped out and conveyed to the shunt box, and then conveyed by a plurality of wire-forming pipes. And when the material passes through the corresponding die holes, the diameter of the material in the form of filaments can be controlled by the aperture of the die holes. And a plurality of die holes arranged in a circular pattern are provided, and the apertures of the plurality of die holes increase in sequence. Therefore, by rotating the die tube, the die holes can be switched. And when the formed POY wire passes through the conveyance of the wire-forming pipe, it can be cooled, thereby enabling the POY wire to be formed. And when it is necessary to adjust the diameter of the POY wire, by pushing the moving ring, the rack can be driven to move longitudinally. Thus, under the meshing transmission with the gear ring, the die tube can be driven to rotate and adjust. And when the required die hole is rotated to correspond to the flow hole, at this time, the positioning pin can correspond to the corresponding card slot. At this time, when the positioning pin is released, the stretched spring in the stressed state can pull the positioning pin to move, insert one end of the positioning pin into the corresponding card slot, and position the rack, thereby realizing the positioning of the die tube.

[0021] In the present invention, after the POY wire is formed, it can be fixed on the corresponding wire shaft. At this time, after the installation shaft receives the driving force of the third conveyor belt, it can rotate, and then drive a plurality of wire shafts clamped on the installation shaft to rotate synchronously, thereby winding the formed POY wire. Therefore, the automatic winding of the formed POY wire can be realized, so as to achieve integrated production when producing the POY wire and effectively improve the working efficiency.

[0022] When the present invention is used to produce POY filaments, it can stably supply the materials for producing POY filaments, and can realize preheating and drying, hot melting and spinning of the materials to form POY filaments. At the same time, it can control the diameter size of the produced POY filaments according to actual needs, so it can produce POY filaments of different sizes. BRIEF DESCRIPTION OF THE DRAWINGS

The wire-forming mechanism is installed on one side of the processing box 12. One side of the wire-forming mechanism extends into the processing box 12 and is connected with the hot-melting mechanism.

[0036] Refer to Figure 4 , The dispersion mechanism includes a driving shaft 7 and a driven shaft 8 respectively rotatably connected to the top of one side of the material box 3. A same first transmission belt 9 is drivingly connected on the driving shaft 7 and the driven shaft 8. One side of the first transmission belt 9 is connected with a connection component. A cleaning frame 5 is slidably connected to the inner wall of the material box 3. The cleaning frame 5 is in contact with the inclined surface of the inclined panel 4. One side of the connection component extends into the material box 3 and is connected with the top of the cleaning frame 5. After the driving shaft 7 receives the power of the drying mechanism, it can drive the first transmission belt 9 to run horizontally. When the first transmission belt 9 is moving, the cleaning frame 5 can be driven through the connection component, so that the cleaning frame 5 can move horizontally back and forth in the material box 3. In the appendix Figure 4 , The connection component includes a connection shaft 10 fixedly installed on the first transmission belt 9. The top end of the connection shaft 10 is rotatably connected with an L-shaped rod 11. A connecting rod 6 is fixedly installed on the top of the cleaning frame 5. A sliding hole is opened on the connecting rod 6. The L-shaped rod 11 penetrates through the sliding hole and is slidably connected with the inner wall of the sliding hole. When the connection shaft 10 moves in a circular motion along with the first transmission belt 9, it can drive the L-shaped rod 11 to move horizontally back and forth. In this way, under the sliding cooperation of the L-shaped rod 11 and the connecting rod 6, the cleaning frame 5 can be driven to move horizontally back and forth along the inner wall of the material box 3, so as to rake loose the material in the material box 3 and prevent the material from condensing into a mass.

[0037] Refer to Figure 6, the drying mechanism includes a drive shaft 14 fixedly installed on the output shaft of the drive motor 13. A support shaft 15 is rotatably connected in the processing box 12. The drive shaft 14 and the support shaft 15 are drivingly connected with the same conveyor belt 16. A heating plate 17 located inside the conveyor belt 16 is fixedly installed in the processing box 12 for heating the conveyor belt 16. One end of the drive shaft 14 extends to the outside of the processing box 12. A rotating shaft 19 is rotatably connected to the bottom of the base 1. A worm 18 located outside the processing box 12 is fixedly sleeved on the drive shaft 14. A worm gear 20 is fixedly sleeved on the rotating shaft 19. The worm 18 meshes with the worm gear 20. A driven gear 21 is fixedly installed at the bottom end of the driving shaft 7. A driving gear 211 is fixedly installed at the top end of the rotating shaft 19. The driving gear 211 meshes with the driven gear 21. When the drive shaft 14 rotates with the output shaft of the drive motor 13, it can drive the conveyor belt 16 to operate. In this way, after the material falls on the conveyor belt 16 along the feeding pipe 22, the material can be conveyed. And after the heating plate 17 (rated power 3.2kW) is powered on, the conveyor belt 16 is heated in sections by thermal radiation (temperature gradient 80 - 150°C). So the material falling on the conveyor belt 16 can be preheated, and at the same time, the moisture on the material can be removed. And the preheated material can be conveyed into the hot melting mechanism under the conveyance of the conveyor belt 16. When the drive shaft 14 rotates, under the meshing drive of the worm 18 and the worm gear 20, the rotating shaft 19 can be driven to rotate. Then, under the meshing drive of the driving gear 211 and the driven gear 21, the driving shaft 7 can be driven to rotate. In this way, when the first conveyor belt 9 moves, driving force can be provided, and at the same time, the power utilization rate of the drive motor 13 can be improved.

[0038] Refer to Figure 7, the hot melting mechanism includes a heating box 24 fixedly installed on the inner wall of the bottom of the processing box 12. A scraper 25 is fixedly installed on one inner wall of the heating box 24. The top of the scraper 25 extends into the processing box 12 and contacts one side of the conveyor belt 16. A moving plate 26 is slidably connected in the heating box 24. A plurality of electric heating rods 27 are fixedly installed at the bottom of the moving plate 26 in a matrix for heating the material to melt the material. The top of the moving plate 26 is connected with a reciprocating component. The reciprocating component is connected with the inner wall of the processing box 12. One side of the reciprocating component extends to the outside of the processing box 12 and is connected with the driving shaft 14 and the winding mechanism. After the reciprocating component receives the driving force of the driving shaft 14, it can operate, thereby providing power to the moving plate 26, so that the moving plate 26 makes a horizontal reciprocating motion in the heating box 24, and then drives the plurality of electric heating rods 27 to make a horizontal reciprocating motion, thus facilitating the hot melting of the material falling into the heating box 24 and making the material in a molten state. The reciprocating component includes a reciprocating lead screw 28 rotatably connected in the processing box 12. A transmission plate 29 is fixedly installed at the top of the moving plate 26.

One end of the reciprocating lead screw 28 extends to the outside of the processing box 12. The reciprocating lead screw 28 and the driving shaft 14 are sleeved with the same second transmission belt 23. The reciprocating lead screw 28 is connected with the winding mechanism. After the second transmission belt 23 receives the driving force of the driving shaft 14, it can drive the reciprocating lead screw 28 to rotate. At this time, under the transmission cooperation of the thread groove and the stopper, the moving plate 26 can be driven to make a horizontal reciprocating motion along the axis direction of the reciprocating lead screw 28, thereby driving the moving plate 26 to make a horizontal reciprocating motion in the heating box 24.

[0039] Refer to Figure 5, the wire forming mechanism includes a delivery pump 33 fixedly installed on one side of the processing box 12. The absorption end of the delivery pump 33 extends into the heating box 24 and is fixedly connected to the inner wall on one side of the heating box 24. A delivery pipe 34 is fixedly installed on the output end of the delivery pump 33. The top end of the delivery pipe 34 extends above the processing box 12 and is fixedly connected to a flow dividing box 35. A circulation hole is formed on one side of the flow dividing box 35. A die tube 36 is rotatably sleeved on the flow dividing box 35. A plurality of equally spaced die holes are formed in an annular shape on the die tube 36. An installation rod 43 is fixedly installed on one side of the flow dividing box 35. The bottom end of the installation rod 43 is fixedly connected to one side of the processing box 12. The same U-shaped rod 44 is fixedly installed on the installation rod 43 and the delivery pipe 34. A plurality of wire forming pipes 45 are fixedly installed through the U-shaped rod 44 at equal intervals. The top ends of the wire forming pipes 45 are in contact with the outer side of the die tube 36. The wire forming pipes 45 correspond to the corresponding die holes respectively. An adjusting component is connected to the die tube 36. The adjusting component is connected to the top of the processing box 12. By starting the delivery pump 33, the molten material in the heating box 24 can be pumped out, transported to the flow dividing box 35, and then transported by a plurality of wire forming pipes 45. When the material passes through the corresponding die holes, the diameter of the material wire can be controlled by the aperture of the die holes. And a plurality of die holes arranged in a circular pattern are provided, and the apertures of the plurality of die holes increase in sequence. Therefore, by rotating the die tube 36, the die holes can be switched. And when the formed POY wire passes through the transportation of the wire forming pipe 45, it can be cooled down, so that the POY wire can be formed. In addition Figure 5 , the adjusting component includes a toothed ring 37 fixedly sleeved on the die tube 36. A fixing plate 38 is fixedly installed on the top of the processing box 12. A moving ring 39 is slidably sleeved on the fixing plate 38. A plurality of card slots 42 are equally spaced on one side of the fixing plate 38. A positioning pin 40 is slidably connected through the inner wall on one side of the moving ring 39. One end of the positioning pin 40 is movably clamped with the plurality of card slots 42 respectively. A tension spring 41 is sleeved on the positioning pin 40 and located outside the moving ring 39. The two ends of the tension spring 41 are fixedly connected to one side of the moving ring 39 and the other end of the positioning pin 40 respectively. A rack 46 is fixedly installed on the top of the moving ring 39. The rack 46 meshes with the toothed ring 37. By pushing the moving ring 39, the rack 46 can be driven to move longitudinally. Therefore, under the meshing transmission action with the toothed ring 37, the die tube 36 can be driven to rotate and adjust. And when the required die hole is rotated to correspond to the circulation hole, at this time the positioning pin 40 can correspond to the corresponding card slot 42. At this time, when the positioning pin 40 is released, the tension spring 41 in the stressed state can pull the positioning pin 40 to move, insert one end of the positioning pin 40 into the corresponding card slot 42, and position the rack 46. In this way, the die tube 36 can be positioned.

[0040] Example 2: Refer to Figure 5, on the basis of Embodiment 1, for the ultra-fine denier single-board ring blowing 5D or 7D POY spinning line equipment proposed in Embodiment 1, a winding mechanism is further proposed. The winding mechanism is installed on the top of the base 1, and the winding mechanism is connected to the hot-melt mechanism.

[0041] Referring to Figure 5 , the winding mechanism includes a wire winding assembly installed on the top of the base 1. The same third transmission belt 30 is drivingly connected to the wire winding assembly and the reciprocating lead screw 28. After the third transmission belt 30 receives the rotational force of the reciprocating lead screw 28, it can drive the wire winding assembly to operate, so as to facilitate the winding of the formed POY wire. In the appendix Figure 5 , the wire winding assembly includes a mounting shaft 31 rotatably clamped on one side of the top of the base 1. A plurality of wire shafts 32 are equally spaced and clamped and sleeved on the mounting shaft 31. The third transmission belt 30 is sleeved on the mounting shaft 31 and is drivingly connected to the mounting shaft 31. After the mounting shaft 31 receives the driving force of the third transmission belt 30, it can rotate, and at this time, it can drive a plurality of wire shafts 32 clamped on the mounting shaft 31 to rotate synchronously, so as to wind the formed POY wire.

[0042] Among them, the first transmission belt 9, the second transmission belt 23, and the third transmission belt 30 can specifically be synchronous belts, and cooperate with corresponding synchronous pulleys for power transmission.

[0043] After the material is placed into the bin 3, the material can be conveyed to the conveyor belt 16 through the blanking pipe 22. By starting the drive motor 13 to drive the drive shaft 14 to rotate, at this time, under the meshing transmission of the worm 18 and the worm wheel 20, the rotating shaft 19 can be driven to rotate. Then, under the meshing transmission of the driving gear 211 and the driven gear 21, the driving shaft 7 can be driven to rotate. At this time, the first transmission belt 9 can be driven to run horizontally. When the first transmission belt 9 moves, the connecting shaft 10 can be driven to move in a circular motion along the first transmission belt 9. At this time, the L-shaped rod 11 can be driven to move synchronously. In this way, under the sliding fit of the L-shaped rod 11 and the connecting rod 6, the cleaning frame 5 can be driven, so that the cleaning frame 5 can move horizontally back and forth in the bin 3. At this time, under the transmission of the connecting component, the first transmission belt 9 can be driven to move, so that the cleaning frame 5 can move horizontally back and forth along the inner wall of the bin 3. In this way, the material in the bin 3 can be raked loose to prevent the material from condensing into a mass, so that the material can be stably conveyed through the blanking pipe 22 to the conveyor belt 16, realizing stable feeding. When the drive shaft 14 rotates with the output shaft of the drive motor 13, the conveyor belt 16 can be driven to operate. In this way, after the material falls on the conveyor belt 16 along the blanking pipe 22, the material can be conveyed. And after the heating plate 17 is powered on, it can generate heat, so that the conveyor belt 16 can be heated. Therefore, the material falling on the conveyor belt 16 can be preheated, and at the same time, the moisture on the material can be removed. And the preheated material can be conveyed into the hot-melting mechanism under the conveying of the conveyor belt 16. The material can be preheated while being conveyed, so that when the hot-melting mechanism is used to hot-melt the material, the hot-melting efficiency can be improved. When the drive shaft 14 rotates, the reciprocating screw rod 28 can be driven to rotate through the second transmission belt 23. At this time, under the transmission cooperation of the thread groove and the stopper, the moving plate 26 can be driven to move horizontally back and forth along the axis of the reciprocating screw rod 28. In this way, the moving plate 26 can be driven to move horizontally back and forth in the heating box 24, and then a plurality of electric heating rods 27 can be driven to move horizontally back and forth, so as to facilitate the hot-melting of the material falling into the heating box 24, making the material in a molten state. The material in the molten state has good fluidity and can be easily pumped out for spinning. Then, by starting the delivery pump 33, the material in the molten state in the heating box 24 can be pumped out and conveyed to the shunt box 35. Then, it can be conveyed by a plurality of filament-forming pipes 45. And when the material passes through the corresponding die holes, the diameter of the material in the form of filaments can be controlled by the aperture of the die holes. And a plurality of die holes arranged in a circular pattern are provided, and the apertures of the plurality of die holes increase in sequence. Therefore, by rotating the die tube 36, the die holes can be switched. And when the formed POY filaments are conveyed through the filament-forming pipes 45, they can be cooled, so that the POY filaments can be formed. And when it is necessary to adjust the diameter of the POY filaments,By pushing the moving ring 39, the rack 46 can be driven to move longitudinally. Thus, under the meshing drive with the toothed ring 37, the model tube 36 can be driven to rotate and adjust. And when the required model hole rotates to correspond to the circulation hole, at this time, the positioning pin 40 can correspond to the corresponding card slot 42. When the positioning pin 40 is released, the tension spring 41 in the stressed state can pull the positioning pin 40 to move, insert one end of the positioning pin 40 into the corresponding card slot 42, and position the rack 46. In this way, the model tube 36 can be positioned. After the POY wire is formed, it can be fixed on the corresponding wire shaft 32. At this time, after the installation shaft 31 receives the driving force of the third transmission belt 30, it can rotate, and at this time, it can drive a plurality of wire shafts 32 mounted on the installation shaft 31 to rotate synchronously, so as to wind up the formed POY wire. Therefore, the automatic winding of the formed POY wire can be realized, so that during the production of the POY wire, integrated production can be realized, and the work efficiency can be effectively improved.
