Description

Technical Field

[0001] This invention relates to the field of spinning technology, specifically to a pressure-boosting filament spinning device. Background Technology

[0002] Spinning, a major process in the manufacture of chemical fibers, involves converting certain polymer compounds into colloidal solutions or melting them into a melt, which is then passed through micropores on a spinneret and extruded into a coagulation bath or air in a thin stream state, where it solidifies or cools to become fibers.

[0003] When applying for this invention, the applicant searched and found that a Chinese patent disclosed "A pressure-boosting spinning device for polyester filament production", with application number "202210818332.5". This patent mainly uses water circulation to continuously cool the take-up roller, achieving a constant water temperature so that the take-up roller does not increase with the temperature of the polyester filament. The water flow drives the blades to rotate, and the wind blown by the blades cools the polyester filament. The wind blows the water curtain, and the water vapor in the water curtain cools the polyester filament. Through triple cooling of the polyester filament, the cooling effect of the polyester filament can be greatly improved.

[0004] However, during the fiber winding process, the newly spun filaments are prone to breakage, resulting in poor spinning effect; and during continuous winding, the continuity of the fibers cannot be guaranteed. Summary of the Invention

[0019] (III) Beneficial Effects

[0020] This invention provides a pressure-boosting filament spinning device. It has the following beneficial effects:

[0021] 1. A pressure mechanism is provided. Driven by the first motor, the rotating shaft and turntable rotate. Under the connection of the connecting rod, the slide plate moves up and down reciprocally, causing the slide rod and pressure plate to move up and down reciprocally. In this way, the pressure plate can pressurize the inside of the yarn output box, improve the continuity of yarn output, and facilitate subsequent winding.

[0022] 2. A cooling mechanism is provided. Driven by a second motor, the reciprocating screw rotates, which in turn drives the moving block and the air hood to move back and forth, thereby cooling the take-up roller and the fiber, increasing the cooling range and improving efficiency.

[0023] 3. A winding mechanism is provided. Driven by a third motor, the motor shaft and the first gear rotate. Since the number of teeth of the first gear is one-quarter of the number of teeth of the second gear, the second gear and the rotating rod rotate intermittently, so that the winding roller can rotate intermittently. This extends the dwell time during the winding of fibers, avoids the breakage of the spinning, and realizes the automated winding of fiber fabric. Attached Figure Description

The spinning machine 2, as a major step in the manufacturing of chemical fibers, is used to spin certain polymer compounds into colloidal solutions or melts them into a molten state. The spinning machine 2 is fixedly connected to the left side of the upper surface of the base plate 1. The pressure mechanism 3 includes a connecting frame 31, inside which a first motor 32 is installed. The output end of the first motor 32 is fixedly connected to a rotating shaft 33. The end of the rotating shaft 33 away from the first motor 32 is fixedly connected to a turntable 34. The front surface of the turntable 34 is rotatably connected to a connecting rod 35. The bottom end of the connecting rod 35 is rotatably connected to a sliding plate 36. The lower surface of the sliding plate 36 is fixedly connected to a sliding rod 37. The bottom end of the sliding rod 37 slides through the interior of the filament output mechanism 4 and is fixedly connected to a pressure plate 38. The pressure plate 38 is slidably connected to the inner wall of the filament output box 41, and the sliding part is sealed.

[0038] The above structure, driven by the first motor 32, drives the rotating shaft 33 and the turntable 34 to rotate. Under the connection of the connecting rod 35, the sliding plate 36 moves up and down reciprocally, causing the sliding rod 37 and the pressure plate 38 to move up and down reciprocally. In this way, the pressure plate 38 can pressurize the inside of the yarn output box 41, thereby improving the continuity of yarn output.

[0039] The filament output mechanism 4 includes an output box 41, which is fixedly connected to the lower surface of the connecting frame 31. A baffle 42 is fixedly connected to the inner wall of the output box 41. A one-way valve 43 is provided in the middle of the baffle 42. A one-way valve 43 is provided on the outer right side of the output box 41. A spinning port 44 is provided through the left side of the output box 41.

A spinneret 45 is provided through the right side wall of the output box 41. Several filament output ports 46 are provided inside the spinneret 45.

[0040] In the above structure, the spinning machine 2 enters the filament box 41 in a fine stream state, and under pressure, it is formed into filaments through the filament outlet 46.

[0041] Example 2:

[0042] like Figure 1-6 As shown, this embodiment of the invention provides a pressure-boosting filament spinning device, including a base plate 1, a spinning machine 2, a pressure mechanism 3, a filament output mechanism 4, a cooling mechanism 5, and a winding mechanism 6. The spinning machine 2, as a major step in the manufacturing of chemical fibers, is used to spin certain polymer compounds into colloidal solutions or melts them into a molten state. The spinning machine 2 is fixedly connected to the left side of the upper surface of the base plate 1. The pressure mechanism 3 includes a connecting frame 31, inside which a first motor 32 is installed. The output end of the first motor 32 is fixedly connected to a rotating shaft 33. The end of the rotating shaft 33 away from the first motor 32 is fixedly connected to a turntable 34. The front surface of the turntable 34 is rotatably connected to a connecting rod 35. The bottom end of the connecting rod 35 is rotatably connected to a sliding plate 36. The lower surface of the sliding plate 36 is fixedly connected to a sliding rod 37. The bottom end of the sliding rod 37 slides through the interior of the filament output mechanism 4 and is fixedly connected to a pressure plate 38. The pressure plate 38 is slidably connected to the inner wall of the filament output box 41, and the sliding part is sealed.

[0043] The above structure, driven by the first motor 32, drives the rotating shaft 33 and the turntable 34 to rotate. Under the connection of the connecting rod 35, the slide plate 36 moves up and down reciprocally, causing the slide rod 37 and the pressure plate 38 to move up and down reciprocally. In this way, the pressure plate 38 can pressurize the inside of the yarn output box 41, improve the continuity of yarn output, and facilitate subsequent winding.

[0044] The filament output mechanism 4 includes an output box 41, which is fixedly connected to the lower surface of the connecting frame 31.

A one-way valve 43 is provided on the outer right side of the output box 41. A spinning port 44 is provided through the left side of the output box 41. The spinning port 44 is connected to the outlet of the spinning machine 2 and is used to allow the filaments spun by the spinning machine 2 to enter the output box 41. A spinneret 45 is provided through the right side wall of the output box 41. Several filament output ports 46 are provided inside the spinneret 45.

[0045] In the above structure, the spinning machine 2 enters the filament box 41 in a fine stream state. Under pressure, the filament is formed through the filament outlet 46 and then enters the cooling box 51.

[0046] The cooling mechanism 5 includes a cooling box 51, which is fixedly connected to the right side of the upper surface of the base plate 1. A second motor 52 is fixedly connected to the upper side of the right outer surface of the cooling box 51. The output end of the second motor 52 extends into the interior of the cooling box 51 and is fixedly connected to a reciprocating screw 53. A moving block 54 is threadedly connected to the outer wall of the reciprocating screw 53. The upper surface of the moving block 54 is slidably connected to the upper inner wall of the cooling box 51, which serves to limit the sliding of the moving block 54. An air outlet hood 55 is fixedly connected to the bottom of the moving block 54 for blowing air and dissipating heat. An exhaust fan 58 is provided in the middle of the upper surface of the cooling box 51. A duct 57 is provided at the exhaust end of the exhaust fan 58. The bottom end of the duct 57 extends into the interior of the cooling box 51 and is fixedly connected to a telescopic hose 56. The end of the telescopic hose 56 away from the duct 57 is connected to the air outlet hood 55. A ventilation mesh 8 is provided on the right outer surface of the cooling box 51 for ventilation and heat dissipation.

[0047] The above structure, driven by the second motor 52, drives the reciprocating screw 53 to rotate, which in turn drives the moving block 54 and the air outlet hood 55 to reciprocate and translate. The exhaust fan 58 exhausts air into the air outlet hood 55, thereby cooling the fibers, increasing the cooling range, and improving efficiency.

[0048] The winding mechanism 6 includes a connecting plate 61, which is fixedly connected to the right side of the inner bottom wall of the cooling box 51. A third motor 62 is fixedly connected to the front surface of the connecting plate 61. A motor shaft 63 is fixedly connected to the output end of the third motor 62. A first gear 64 is fixedly connected to the end of the motor shaft 63 away from the third motor 62. A second gear 65 is meshed with the bottom of the first gear 64. The number of teeth of the first gear 64 is one-quarter of the number of teeth of the second gear 65. When the first gear 64 rotates, it drives the second gear 65 to rotate intermittently. A rotating rod 66 is fixedly connected to the middle of the second gear 65. The rotating rod 66 is rotatably connected to the connecting plate 61 and serves as a positioning function. A winding roller 67 is detachably connected to the outer wall of the rotating rod 66. The winding roller 67 rotates and winds the gear.

[0049] The above structure, driven by the third motor 62, drives the motor shaft 63 and the first gear 64 to rotate. Since the number of teeth of the first gear 64 is one-quarter of the number of teeth of the second gear 65, it drives the second gear 65 and the rotating rod 66 to rotate intermittently, so that the winding roller 67 can rotate intermittently. In this way, the dwell time can be extended during the winding of fibers, avoiding the breakage of the spinning and realizing the automated winding of the fiber fabric.

[0050] A guide plate 7 is fixedly connected to the left inner wall of the cooling box 51 and above the spinneret 45. The guide plate 7 is inclined and has several ventilation holes inside to guide the spinning.

[0051] The front of the cooling box 51 is hinged with a cover plate 9, which makes it easy to open and put in and take out the winding roller 67.

[0052] Working principle: When using this pressurized filament spinning device, open the cover plate 9, install the take-up roller 67 on the connecting plate 61, close the cover plate 9, and turn on the switches of the spinning machine 2, the first motor 32, the second motor 52, the exhaust fan 58, and the third motor 62. The spinning machine 2 enters the filament box 41 in a thin stream state. Under pressure, the filaments are formed through the filament outlet 46 and enter the cooling box 51. The exhaust hood 55 moves back and forth to cool the filaments. The take-up roller 67 rotates intermittently, thereby extending the residence time during the fiber winding process, avoiding filament breakage, and realizing automated winding of the fiber fabric.
