Description

Technical Field

[0001] This invention relates to the field of spinning technology, and in particular to a spinning apparatus for producing high-strength nylon military-grade yarn. Background Technology

[0002] Spinning is a key process in the manufacture of chemical fibers. It refers to the process of forming fibers by pressing a polymer compound into a colloidal solution or melt through the fine holes of a spinneret. Nylon is generally produced as a high-strength military yarn, and special spinning equipment is used in its production.

[0003] In existing spinning devices, a melting box is set up to facilitate the rapid melting of nylon feed material under the action of a stepper motor, rotating rod, and mixing plate. The molten liquid is then easily sprayed out through an electric spray pipe, allowing for cooling in a cooling cylinder. Simultaneously, a cooling rod and fan blades further increase the cooling speed. A drive motor, first gear, and second gear are set up to easily drive the drive rod and reciprocating screw to rotate. This allows the limit ring to move through the screw nut, facilitating the uniform winding of the cooled yarn when the drive rod drives the winding tube to rotate.

[0004] However, in the actual spinning process, the winding tube exerts a force on the yarn when it rotates to wind it. Although the yarn is cooled and wound inside the cooling cylinder, the force exerted on the yarn during the winding process also acts on the part of the yarn ejected from the electric jet tube. Since the yarn at the point where the electric jet tube is ejected is at a high temperature, the force generated during the winding process can easily pull some of the yarn, making it thinner, or even causing the ejected yarn to break, thus reducing the quality of the spinning process. Therefore, there are areas for improvement. Summary of the Invention

[0031] The following is in conjunction with the appendix Figures 1-8 The present invention will be described in further detail below.

[0032] Reference Figures 1-8This invention discloses a spinning device for producing high-strength nylon military yarn, including a mounting box 1. The bottom of the mounting box 1 is supported by a bracket 2. A top plate 10 is provided at the upper part of the mounting box 1. The top plate 10 is fastened to the inner wall of the mounting box 1 by two mounting plates 11. A melting box 8 is provided on the top plate 10 through a movable structure.

[0033] A second motor 20 is installed in the middle of the upper part of the melting box 8. A feed pipe is installed on the melting box 8. The output shaft of the second motor 20 is inserted into the melting box 8 and a stirring rod is set at one end. An electric jet pipe 9 is set in the middle of the lower part of the melting box 8. A heater is set in the melting box 8.

[0034] Mounting rods 4 are connected to the middle of the inner walls on both sides of the mounting box 1. A cooling frame 3 is installed between the two mounting rods 4. A first cooling structure is set on the inner walls on both sides of the cooling frame 3. A baffle structure is set on both sides of the cooling frame 3. A feeding groove 38 is opened in the middle of the bottom of the cooling frame 3. A wire guide structure is set in the feeding groove 38. A winding structure is set on the lower inner wall of the mounting box 1.

[0035] The baffle structure includes through slots 6 on the inner walls of the left and right sides of the cooling frame 3. Both through slots 6 have baffles 7 that move through them. The baffles 7 are "L" shaped. Electric telescopic rods 5 are installed on the outer sides of the left and right sides of the cooling frame 3. One end of the output shaft of the electric telescopic rod 5 is connected to the baffle 7.

[0036] The guide wire structure includes grooves 39 formed on both sides of the feed trough 38. A rotating rod 40 is rotatably connected between the front and rear ends of the groove 39. A sleeve 41 is fixedly fitted onto the rotating rod 40. First, the raw material is added to the melting tank 8 through the feed pipe. The raw material is heated and melted in the melting tank 8 by a heater. At the same time, the second motor 20 on the melting tank 8 can be started to drive the stirring rod to rotate, accelerating the melting efficiency of the raw material in the melting tank 8. Then, the raw material is sprayed into wires onto the baffle 7 through the electric spray pipe 9. A certain length of wire is reserved on the baffle 7 for cooling. The electric telescopic rod 5 drives the baffle 7 to move within the cooling frame 3, causing the reserved wire to fall to the lower inner wall of the cooling frame 3. At this time, the wire is wound up, and the electric telescopic rod 5 drives the baffle 7 to move in the opposite direction and reset, continuing to cool the sprayed wire. This reduces the problem of the wire becoming thinner or even breaking due to pulling during winding. In addition, a sleeve 41 is set at the feeding trough 38. When the wire is pulled and fed at the feeding trough 38, it can drive the sleeve 41 to rotate, thereby reducing the static friction between the sleeve and the wire and avoiding wear on the wire.

[0037] See Figures 1-7The movable structure includes a central groove 13 on the top plate 10, a first reciprocating screw 14 rotatably connected between the front and rear end walls of the central groove 13, a first motor 12 installed at the middle of the rear side of the top plate 10, one end of the output shaft of the first motor 12 connected to the first reciprocating screw 14, a movable seat 15 slidably disposed in the central groove 13, a first screw sleeve 16 fixedly passing through the middle of the movable seat 15, the first screw sleeve 16 being sleeved on the first reciprocating screw 14, a sleeve block 17 installed at the middle of the lower part of the movable seat 15, a sliding plate 18 provided at the bottom end of the sleeve block 17, the bottom end of the sleeve block 17 being slidably disposed in a transverse groove on the sliding plate 18, an installation frame 19 provided at the middle of both sides of the sliding plate 18, the installation frame 19 being disposed on the melting box 8, a guide structure provided between the sliding plate 18 and the top plate 10, and a second cooling structure provided at both ends of the lower part of the sliding plate 18;

[0038] The guiding structure includes protrusions 21 at both ends of the sliding plate 18, with insert rods 22 fixedly passing through them. Guide grooves 23 are provided on both sides of the bottom of the top plate 10. The guide grooves 23 are "W" shaped. The top of the insert rod 22 is inserted into the guide groove 23. When the wire is being sprayed, the first motor 12 on the top plate 10 is started to drive the first reciprocating screw 14 to rotate. The first screw sleeve 16 drives the moving seat 15 to move back and forth in the middle groove 13. By using the sliding of the insert rod 22 in the guide groove 23, the melting box 8 and the electric spray pipe 9 can be driven to move back and forth along the length and width of the top plate 10, so that the sprayed wire is evenly laid on the baffle 7, so that a certain length of wire can be reserved on the baffle 7 for cooling.

[0039] See Figure 1 , Figure 6 and Figure 8 The second cooling structure includes an L-shaped plate 24 fastened to both ends of the sliding plate 18 by bolts. The L-shaped plate 24 has a through slot 25 for the insertion rod 22 to pass through. A fastening frame 26 is provided at the bottom of the L-shaped plate 24. The first cooling cylinder 27 is fixed through the fastening frame 26. An inner plate 28 is provided on the inner wall of the first cooling cylinder 27. A third motor 29 is installed on the inner plate 28. A first fan blade 30 is provided at one end of the output shaft of the third motor 29.

[0040] The first cooling structure includes an inner groove 31 formed on the inner walls of both sides of the cooling frame 3. A movable block 32 is slidably arranged in the inner groove 31. A fixed rod 34 is connected to the movable block 32. Multiple connecting rods 35 are connected to one end of the fixed rod 34. A second cooling cylinder 36 is installed at one end of the connecting rod 35. A fourth motor 37 is installed at one end of the fixed rod 34. A second fan blade is installed at one end of the output shaft of the fourth motor 37. A driving rod 33 is connected to the second cooling cylinder 36. The top end of the driving rod 33 is connected to the fastening frame 26. During the spinning process, the third motor 29 and the fourth motor 37 are started to drive the first fan blade 30 and the second fan blade to rotate. When the melting box 8 moves, it drives the fastening frame 26 and the second cooling cylinder 36 to move synchronously through the driving rod 33. This cools the reserved yarn and the yarn sprayed from the electric jet pipe 9 within the cooling frame 3, making the cooling of the yarn more thorough.

[0041] See Figure 1 The winding structure includes fixed blocks 42 connected to both sides of the lower inner wall of the mounting box 1, a winding rod 44 rotatably connected between the two fixed blocks 42, a winding drum 45 sleeved on the winding rod 44, a fifth motor 43 installed on one of the fixed blocks 42, one end of the output shaft of the fifth motor 43 connected to the winding rod 44, and a wire guide structure provided on the two fixed blocks 42.

[0042] The lead wire structure includes a U-shaped plate 46 connected to the rear side of the fixed block 42. One end of the U-shaped plate 46 rotates through the second reciprocating lead screw 47. A limiting rod 48 connects the two U-shaped plates 46. A second lead screw sleeve 49 is fitted onto the second reciprocating lead screw 47 and the limiting rod 48. An L-shaped rod 50 is connected to the top of the second lead screw sleeve 49. A lead wire coil 51 is installed at one end of the L-shaped rod 50. A second gear 53 is fitted onto the second reciprocating lead screw 47. A first gear 52 is fitted onto the winding rod 44. The first gear 52 and the second gear 53 mesh with each other. When winding, the fifth motor 43 on the starting fixed block 42 drives the winding rod 44 and the winding drum 45 to rotate. The yarn is wound on the winding drum 45. Through the first gear 52 and the second gear 53, the winding rod 44 drives the second reciprocating screw 47 to rotate. The second screw sleeve 49 drives the guide ring 51 to move, thereby evenly winding the yarn passing through the guide ring 51 onto the winding drum 45, improving the winding quality.

[0043] The implementation principle of a spinning device for producing high-strength nylon military-grade yarn according to an embodiment of the present invention is as follows: First, raw materials are added to the melting tank 8 through the feed pipe. The raw materials are heated and melted in the melting tank 8 by a heater. At the same time, the second motor 20 on the melting tank 8 can be started to drive the stirring rod to rotate, thereby accelerating the melting efficiency of the raw materials in the melting tank 8. Next, the raw materials are sprayed into yarn onto the baffle 7 through the electric spray pipe 9. Simultaneously, the first motor 12 on the top plate 10 is started to drive the first reciprocating screw 14 to rotate. The first screw sleeve 16 drives the moving seat 15 to move back and forth in the intermediate groove 13. The melting tank 8 and the electric spray pipe 9 move back and forth along the length and width of the top plate 10 by sliding the insert rod 22 in the guide groove 23, thereby evenly laying the sprayed filaments onto the baffle 7. This allows a certain length of filaments to be pre-reserved on the baffle 7. During cooling, the third motor 29 and the fourth motor 37 are started to drive the first fan blade 30 and the second fan blade to rotate. When the melting tank 8 moves, it drives the fastening frame 26 and the second cooling cylinder 36 to move synchronously through the driving rod 33, thereby allowing the pre-reserved filaments to be pre-reserved on the baffle 7. The silk thread, as well as the silk thread sprayed from the electric jet pipe 9, are cooled to ensure more thorough cooling. Then, the electric telescopic rod 5 drives the baffle 7 to move within the cooling frame 3, causing the reserved silk thread to fall to the lower inner wall of the cooling frame 3. At this time, the fifth motor 43 on the fixed block 42 drives the winding rod 44 and the winding drum 45 to rotate, and the silk thread is wound on the winding drum 45. Furthermore, through the first gear 52 and the second gear 53, the winding rod 44 drives the second reciprocating screw 47 to rotate as it rotates, and the second screw sleeve 49 drives the lead wire. As the coil 51 moves, the filament passing through the lead coil 51 is evenly wound onto the take-up drum 45. After the reserved filament falls off the baffle 7, the electric telescopic rod 5 drives the baffle 7 to move in the opposite direction and reset, continuing to cool the sprayed filament. During winding, this reduces the problem of the filament becoming thinner or even breaking due to pulling. Furthermore, a sleeve 41 is set at the feed trough 38. When the filament is pulled and fed at the feed trough 38, it can drive the sleeve 41 to rotate, thereby reducing the static friction between the sleeve and the filament and avoiding wear on the filament. This is how the spinning process is achieved.

[0044] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
