Description

Technical Field

[0001] This invention relates to the field of short fiber drawing equipment technology, specifically to a short fiber bundle drawing machine. Background Technology

[0002] In the production process of synthetic staple fibers, the fiber bundles (filament bundles) after spinning, cooling, and oiling need to be bundled to form processing units of sufficient scale. They then enter a drawing machine for directional stretching to improve fiber strength. However, before drawing, the fiber bundles often contain impurities such as spinning oil, oligomers, and dust, and the fibers are tightly bound and randomly arranged. Therefore, an efficient and uniform opening and washing pretreatment system is crucial.

[0003] A search revealed that patent CN219586355U discloses a short fiber bundle stretching mechanism, comprising a base plate, a support rod fixedly mounted on one end of the upper surface of the base plate, a spraying box fixedly mounted on the upper end of the support rod, a second rotating rod arrayed at the lower end of the interior of the spraying box, a first motor fixedly mounted on one end of the spraying box, a first rotating rod fixedly mounted on the output end of the first motor, and a disinfection water tank fixedly mounted on one side of the outer surface of the spraying box. First, short fibers are placed on the first rotating rod and the first motor is started. The first motor drives the first rotating rod to rotate, conveying the short fibers forward into the spraying box. Then, a water pump is turned on, drawing disinfectant water from the disinfection water tank. The water is then sprayed onto the short fibers through a spraying pipe, thus disinfecting them.

[0004] Existing technical solutions for washing fiber bundles still have the following drawbacks: Traditional steam washing usually uses fixed nozzles or simple oscillating nozzles. For very fluffy fiber materials, steam has difficulty penetrating the interior, which can easily lead to only surface washing and incomplete internal fiber washing and disinfection.

[0005] To address the permeation problem, existing technologies may employ mechanical stirring, beating, or additional vibration devices. However, these devices are typically independent of the steam system, require an additional power source, are structurally complex, energy-intensive, and cumbersome to control. More importantly, their actions cannot be coordinated with the steam flow. For steam washing of high-grade synthetic fibers and medical fibers that require low damage and high uniformity, excessive beating may lead to fiber damage (especially for high-grade and medical fibers), or the beating force may not match the steam permeation requirements. Summary of the Invention

[0006] The purpose of this invention is to provide a short fiber bundle drawing machine, which aims to solve the problems existing in the current short fiber bundle drawing machine.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a short fiber bundle drawing machine, comprising a steam washing chamber and a guide roller assembly, wherein guide roller assemblies are provided at both ends of the steam washing chamber, the guide roller assemblies being used to convey fiber bundles, and further comprising:

[0008] A steam delivery system is installed inside the steam washing box. The steam delivery system includes a drive unit, a rotating branch pipe, and a steam nozzle. The steam nozzle is connected to the rotating branch pipe. The drive unit adjusts the airflow direction by controlling the rotation of the rotating branch pipe.

[0009] A support frame that is fixedly installed inside the steam washing box;

[0010] A rocker arm and a striking mechanism are rotatably connected to a support frame, the striking mechanism being connected to the rocker arm;

[0011] The slapping mechanism includes a swinging component, a slapping component, a connecting rod, a main rod, and a wing structure. The swinging component is mounted on the main rod, and the main rod is rotatably connected to the support frame. The connecting rod is hinged between the swinging component and the rocker arm. The slapping component is connected to the swinging component. A wing structure is installed at one end of the main rod near the electronically controlled locking module. The slapping component can contact the fiber bundle.

[0012] An electrically controlled locking module is installed on the outside of the steam washing box. The electrically controlled locking module includes a base, an electromagnet, a pressure sensor, and an elastic buffer. The base is installed on the outside of the steam washing box, the electromagnet is installed on the surface of the base, and the elastic buffer can contact the pressure sensor. The electromagnet controls the beater to detach from the fiber bundle by adsorbing the wing structure, and at the same time controls the rocker arm to move away from the steam nozzle.

[0013] As a further embodiment of the present invention, the steam conveying system further includes a conveying main pipe and a transmission component. The conveying main pipe is installed on the outside of the steam washing tank, the rotating branch pipe is connected to the conveying main pipe, the transmission component is installed on the rotating branch pipe, and the driving component is connected to the transmission component in a transmission manner.

[0014] As a further embodiment of the present invention, the high-pressure steam ejected from the steam nozzle can drive the rocker arm and the beating mechanism to perform reciprocating rotational motion. The beating mechanism improves the washing uniformity and penetration by beating the fiber bundles. The beating component is a beating plate or a loosening roller.

[0015] As a further embodiment of the present invention, the elastic buffer includes a movable pin and a spring. The movable pin is connected to the base by the spring. A pressure sensor is installed on the side of the base opposite to the movable pin, and the movable pin can contact the pressure sensor.

[0016] As a further embodiment of the present invention, the rocker arm is provided with a pin, the pin being rotatably connected to the support frame, and both the support frame and the rocker arm are provided with two sets of elastic limiting structures and protrusion structures, the protrusion structures being able to contact the elastic limiting structures.

[0018] As a further embodiment of the present invention, the steam washing box is provided with a yarn feeding port and a yarn outlet at both ends, and both the yarn feeding port and the yarn outlet are provided with a yarn guide roller assembly. A control display panel is installed on the outside of the steam washing box.

[0019] The beneficial effects of the present invention are as follows: (1) The present application can select different working modes according to different fiber types. By directly converting the kinetic energy of high-pressure steam into the swing mechanical energy of the rocker arm and the rotational beating mechanical energy of the beating component, it can not only break the fiber clumps of fluffy fiber materials, but also ensure that all surface fibers have the opportunity to be exposed to steam, thereby improving the uniformity and permeability of steam in the fibers. By controlling the rotation of the rotating branch pipe to adjust the airflow direction, it can achieve uniform washing of high-grade artificial fibers and medical fibers, and realize the adaptive adjustment of steam washing of different types of fiber materials.

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0038] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0039] Please see Figures 1 to 6 In one embodiment of the present invention, a short fiber bundle drawing machine includes a steam washing chamber 1, a control display panel 8, and a guide roller assembly 2. The steam washing chamber 1 has a feeding port 11 and a discharging port 12 at both ends, and both the feeding port 11 and the discharging port 12 are equipped with the guide roller assembly 2. The guide roller assembly 2 is used to convey fiber bundles 9. The control display panel 8 is installed on the outside of the steam washing chamber 1. The machine also includes:

[0040] The steam delivery system 3 is installed in the steam washing box 1. The steam delivery system 3 includes a drive unit 33, a rotating branch pipe 32 and a steam nozzle 34. The steam nozzle 34 is connected to the rotating branch pipe 32. The drive unit 33 adjusts the airflow direction by controlling the rotation of the rotating branch pipe 32.

[0041] A support frame 6 is fixedly installed inside the steam washing box 1;

[0042] A rocker arm 4 and a beating mechanism 5 are rotatably connected to a support frame 6. The rocker arm 4 is provided with a pin 41, which is rotatably connected to the support frame 6. Both the support frame 6 and the rocker arm 4 are provided with two sets of elastic limiting structures 61 and protruding structures 42. The protruding structures 42 can contact the elastic limiting structures 61. The beating mechanism 5 is connected to the rocker arm 4. The high-pressure steam ejected by the steam nozzle 34 can drive the rocker arm 4 and the beating mechanism 5 to perform reciprocating rotational motion. The beating mechanism 5 improves the washing uniformity and penetration by beating the fiber bundles 9. Both the elastic limiting structures 61 and the protruding structures 42 are made of rubber.

[0043] An electrically controlled locking module 7 is installed on the outside of the steam washing box 1. The electrically controlled locking module 7 is used to control the beating mechanism 5 to disengage from the fiber bundle 9 and at the same time control the rocker arm 4 to move away from the steam nozzle 34.

[0044] Please see Figures 1 to 4 Furthermore, the steam conveying system 3 also includes a conveying main pipe 31 and a transmission component 35. The conveying main pipe 31 is installed on the outside of the steam washing box 1. The rotating branch pipe 32 is connected to the conveying main pipe 31. The transmission component 35 is installed on the rotating branch pipe 32. The driving component 33 is connected to the transmission component 35. The driving component 33 can be designed as a drive motor and a worm gear. The drive motor is connected to the worm gear. The transmission component 35 can be designed as a worm wheel. The worm gear is connected to the worm wheel.

[0045] In this embodiment of the invention, for steam washing of high-grade synthetic fibers and medical fibers that require low damage and high uniformity, under the premise that the electromagnet 72 is used to electromagnetically attract and fix the wing structure 55, the drive component 33 controls the rotating branch pipe 32 and the steam nozzle 34 through the transmission component 35 to adjust the direction and inclination of the airflow according to the preset frequency and preset angle, so that the steam can wrap each fiber without dead angles, maximize the contact area between the steam and the fiber, and achieve uniform and thorough washing and disinfection.

[0046] Please see Figures 2 to 5 In another embodiment of the present invention, the beating mechanism 5 includes a swing member 51, a beating member 52, a connecting rod 53, a main rod 54, and a wing structure 55. The swing member 51 is mounted on the main rod 54, and the main rod 54 is rotatably connected to the support frame 6. The connecting rod 53 is hinged between the swing member 51 and the rocker arm 4. The beating member 52 is connected to the swing member 51. The wing structure 55 is installed at one end of the main rod 54 near the electronically controlled locking module 7. The beating member 52 can contact the fiber bundle 9. The beating member 52 is an opening roller, but it can also be replaced by a beating plate. The swing member 51 is a T-shaped swing arm or a curved plate. The wing structure 55 is a plastic wing-shaped plate wrapped with a magnetic core.

[0047] In this embodiment of the invention, for steam washing of very fluffy fiber materials, the control display panel 8 controls the electromagnet 72 to be de-energized. The elastic force of the elastic buffer 74 drives the main rod 54, the swinging member 51, and the rocker arm 4 to rotate in opposite directions through the wing structure 55, so that one end of the rocker arm 4 can be positioned above the steam nozzle 34. The high-pressure steam flow ejected from the steam nozzle 34, which is perpendicular to the surface of the fiber bundle 9, can impact the rocker arm 4. The impact force of the high-pressure steam flow, combined with the limiting force of the elastic limiting structure 61, allows the rocker arm 4 to swing back and forth about the pin 41 as the axis. The reciprocating rocker arm 4 drives the swinging member 51 and the beating member 52 to swing back and forth about the main rod 54 as the axis through the connecting rod 53. The reciprocating beating member 52 (beating plate or opening roller) can make the shifting The moving fiber bundle 9 vibrates, causing the fiber layer to be continuously thrown up and loosened, allowing steam to pass through the gaps between the fibers. This not only breaks up fiber clumps but also ensures that all surface fibers have the opportunity to be exposed to steam, thereby improving the uniformity and permeability of steam in the fibers. This inspiration comes from an automatically rotating irrigation nozzle (the water flow from the nozzle impacts the water-dispensing arm to achieve 360° automatic irrigation). The kinetic energy of high-pressure steam is converted into the kinetic energy of beating and vibrating the fiber bundle 9, which can effectively solve the problem of loose fiber materials easily clumping and uneven permeability during steam washing. The power of the beating action comes entirely from the steam used for washing, without the need for an additional motor or pneumatic system to drive the beating mechanism 5.

[0048] Please see Figure 1 , Figures 6 to 7 In another embodiment of the present invention, the electronically controlled locking module 7 includes a base 71, an electromagnet 72, a pressure sensor 73, and an elastic buffer 74. The base 71 is installed on the outside of the steam washing tank 1, the electromagnet 72 is installed on the surface of the base 71, and the elastic buffer 74 includes a movable pin and a spring, neither of which is marked in the figure. The movable pin is connected to the base 71 by the spring. The pressure sensor 73 is installed on the side of the base 71 away from the movable pin, and the movable pin can contact the pressure sensor 73. The electromagnet 72 controls the beater 52 to detach from the fiber bundle 9 by adsorbing the wing structure 55, and at the same time controls the rocker arm 4 to move away from the steam nozzle 34.

[0049] In this embodiment of the invention, when the swinging member 51, the striking member 52, and the main rod 54 reciprocate, the wing structure 55 compresses the elastic buffer member 74 at a certain frequency. The compressed movable pin is used to trigger the pressure sensor 73. The pressure sensor 73 transmits the pressure signal to the control display panel 8. The control display panel 8 can monitor the striking force of the striking member 52 on the fiber material according to the pressure parameters, so as to control the magnitude of the striking force in real time by adjusting the steam flow rate. On the other hand, when the control display panel 8 receives the pressure signal, it can automatically and instantaneously control the electromagnet 72 to be energized. The energized electromagnet 72 is used to magnetically fix the wing structure 55, so as to automatically control the striking mechanism 5 to detach from the fiber bundle 9 and at the same time move the rocker arm 4 away from the steam nozzle 34, which is suitable for stopping the striking vibration of the fiber material.

[0050] In summary, this application can select different working modes according to different fiber types. By directly converting the kinetic energy of high-pressure steam into the swinging mechanical energy of the rocker arm 4 and the rotating beating mechanical energy of the beating component 52, it can not only break up the fiber clumps of fluffy fiber materials, but also ensure that all surface fibers have the opportunity to be exposed to steam, thereby improving the uniformity and permeability of steam in the fibers. By controlling the rotation of the rotating branch pipe 32 to adjust the airflow direction, it can achieve uniform washing of high-grade synthetic fibers and medical fibers, realizing adaptive adjustment of steam washing for different types of fiber materials.

[0051] In this application, on the one hand, the beating force of the beating component 52 on the fiber material can be monitored, so that the magnitude of the beating force can be controlled in real time by adjusting the steam flow rate. On the other hand, when the control display panel 8 receives the pressure signal, the beating mechanism 5 is controlled to detach from the fiber bundle 9 by the electromagnet 72 magnetically fixing the wing structure 55, thereby realizing automatic feedback adjustment of the beating force and automatic switching of the washing mode during the washing process of the fiber material.
