Description

Technical Field

[0001] The invention relates to the technical field of nylon yarn production, in particular to a traction device for nylon yarn production. Background Art

[0002] In industrial production, the nylon yarn traction device is a key equipment widely used in the textile, packaging, building materials and other industries. It is mainly used for the transportation, traction and processing of nylon yarn. The device applies tension to the nylon yarn through a mechanical transmission system to ensure its stable transportation in the production process. During the high-speed traction process, the nylon yarn may break due to factors such as material fatigue, uneven tension or external interference. However, most existing nylon yarn traction devices focus on traction efficiency and do not consider enough protective measures when the nylon yarn breaks. When the nylon yarn breaks, the broken yarn will rebound or splash under the action of residual tension. The splashing broken yarn can easily scratch the operator's skin or even damage his eyes, causing personal injury to the operator, resulting in low safety when the equipment is used.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only 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 making creative efforts are within the scope of protection of the present invention.

[0036] During high-speed traction, nylon wire may break due to factors such as material fatigue, uneven tension or external interference. However, most existing nylon wire traction devices focus mainly on traction efficiency and do not give enough consideration to protective measures when the nylon wire breaks. When the nylon wire breaks, the broken wire will rebound or splash under the action of residual tension. The splashing broken wire can easily scratch the operator's skin or even damage his eyes, causing personal injury to the operator, resulting in low safety when using the equipment.

[0037] To solve the defects of the above traction device during use, please refer to Figure 1-Figure 7The present invention provides a traction device for nylon yarn production, which can prevent broken yarns from splashing and protect operators. The traction device is based on a bracket 1. A traction mechanism 6 is provided on the front of the bracket 1. The traction mechanism 6 includes a nylon yarn reel 61 and a winding roller 62 that are rotatably installed on both sides of the bracket 1. A servo motor 64 that acts on the winding roller 62 is installed on the back of the bracket 1. A control switch 9 electrically connected to the servo motor 64 is also installed on the side of the bracket 1. The servo motor 64 can be turned on and off by the control switch 9. Driving the servo motor 64 can drive the winding roller 62 to rotate, pull, and reel in the nylon yarn on the nylon yarn reel 61. A protective cover 2 is also installed on the front of the bracket 1 to wrap the traction path of the traction mechanism 6. The protective cover 2 can enclose the nylon yarn being pulled inside it. The material of the protective cover 2 is transparent acrylic, which is convenient for the operator to check the traction state of the nylon yarn and The operating status of the traction mechanism 6 is observed; wherein, the protective cover 2 is composed of an upper half cover 21 and a lower half cover 22 respectively arranged on the upper and lower sides of the traction mechanism 6, and an opening and closing mechanism 3 is installed on the back of the bracket 1 to drive the upper half cover 21 and the lower half cover 22 to slide relative to each other in the up and down directions. The opening and closing of the protective cover 2 can be controlled by the opening and closing mechanism 3. During traction, the upper half cover 21 and the lower half cover 22 are controlled to approach each other and merge to close the protective cover 2. At this time, the protective cover 2 is wrapped around the outside of the traction mechanism 6 and the nylon wire. On the one hand, it can prevent the nylon wire from absorbing dust and being physically damaged by the outside during movement, and has a dust-proof effect on the nylon wire. On the other hand, when the nylon wire breaks accidentally, the broken wire can be blocked to prevent the broken wire from splashing and causing harm to the operator.

[0038] The cam 32 is connected to the upper and lower covers 21 and 22 by the cam 33, and the cam 33 is connected to the lower cover 21 and the lower cover 22 by the cam 33.

[0039] When the traction mechanism 6 is running, if the protective cover 2 is accidentally opened, the high-speed traction of the nylon thread may also cause scratches to the operator. In order to solve this technical problem, a power-off switch 4 electrically connected to the traction mechanism 6 is also provided. The servo motor 64 is electrically connected to the power-off switch 4. When the power-off switch 4 is pressed, the servo motor 64 is in a power-off state. A stopping mechanism 5 is provided between the power-off switch 4 and the opening and closing mechanism 3. The setting of the stopping mechanism 5 can trigger the power-off switch 4 when the protective cover 2 is opened, cut off the power supply of the servo motor 64, and automatically stop the traction mechanism 6. In order to achieve the above-mentioned effect of the braking mechanism 5, two elastic telescopic rods 51 are fixedly installed on one side of the back of the bracket 1. The power-off switch 4 is arranged between the two elastic telescopic rods 51. The free ends of the two elastic telescopic rods 51 are fixedly installed with a pressure plate 52. One end of the pressure plate 52 is fixedly connected to a trigger rod 53 for pressing the power-off switch 4. A spur gear 54 meshing with the half gear 31 is also rotatably installed on the back of the bracket 1. The axis of the spur gear 54 is fixedly connected to a top column 55. The other end of the pressure plate 52 abuts on the top column 55. The top column 55 is provided with a transition curved surface 56. Figure 1 and Figure 2 The protective cover 2 in the open state, combined with Figure 3 and Figure 4 As shown, the pressure plate 52 drives the trigger rod 53 to press the power-off switch 4 through the elastic force of the elastic telescopic rod 51. At this time, the servo motor 64 is in the power-off state. During traction, the hydraulic rod 35 is driven to drive the upper half cover 21 and the lower half cover 22 to slide and merge to close, which can drive the half gear 31 to rotate. The rotation of the half gear 31 drives the spur gear 54 to rotate. The rotation of the spur gear 54 drives the top column 55 to rotate. The end of the pressure plate 52 close to the top column 55 is provided with a chamfer, which contacts the transition curved surface 56. As the top column 55 rotates, the transition curved surface 56 can The pressure plate 52 is pushed upward, and the elastic telescopic rod 51 is deformed at this time. The pressure plate 52 drives the trigger rod 53 to move away from the power-off switch 4, and the servo motor 64 can be in the energized state. The traction mechanism 6 can pull the nylon wire. When the protective cover 2 is opened during the traction process, the top column 55 can be reversed in the same way. The pressure plate 52 can squeeze the power-off switch 4 again through the elastic force of the elastic telescopic rod 51, cutting off the power supply of the servo motor 64 and forcibly stopping the traction mechanism 6 to avoid accidental scratches on the operator, thereby improving the safety of equipment use.

[0040] Example 2

[0041] After the nylon wire breaks, it is often necessary to check the break position to confirm the cause of the break and prevent potential risks so as to take corresponding preventive measures. However, the nylon wire will rebound and swing around at the moment of breakage, making it difficult for the operator to find the position of the broken wire in the protective cover 2. In order to solve this technical problem, please refer to Figure 1 and Figure 7A guide mechanism 7 is provided on the lower half cover 22. The guide mechanism 7 includes a guide box 71 fixedly mounted on the bottom of the lower half cover 22. An opening communicating with the guide box 71 is provided at the bottom of the lower half cover 22. A filter screen 72 and an air flow fan 73 arranged in parallel from top to bottom are fixedly mounted inside the guide box 71. When the traction mechanism 6 is in operation, the air flow fan 73 is driven to generate negative pressure inside the guide box 71. In this way, when the nylon wire breaks, the broken wire can be affected by the airflow and sucked into the guide box 71. The operator can directly find the broken wire from the guide box 71 for easy inspection.

[0042] Since the breaking position of the nylon wire is random when it breaks, in order to improve the adaptability of the guide box 71 to the broken wire position, a tensioning member is provided between the nylon wire reel 61 and the wire winding roller 62. The tensioning member is provided directly above the guide box 71. The tensioning member includes a guide wheel 631 rotatably mounted on the front of the bracket 1 and a pair of tension wheels 632 of the same height. The guide wheel 631 is provided between the pair of tension wheels 632, and a height difference is provided between the guide wheel 631 and the tension wheel 632. It should be noted that a tension sensor can be installed on the guide wheel 631 to transmit a signal to the control module of the device to stop the operation of the traction mechanism 6 in time when the nylon wire breaks. On the one hand, the guide wheel 631 can ensure the tension of the nylon wire during traction, and on the other hand, it can control the nylon wire to be in a bending state in this path. In this way, when the nylon wire breaks, the probability of the nylon wire breaking at this position can be increased, which is helpful for the guide box 71 to absorb the broken wire.

[0043] Example 3

[0044] Since the traction mechanism 6 is in operation, the protective cover 2 is in a closed state, and the traction mechanism 6 generates heat during operation. In order to solve the heat dissipation problem of the protective cover 2, refer to Figure 5 and Figure 6As shown, two sets of ventilation mechanisms 8 are installed inside the protective cover 2. The two sets of ventilation mechanisms 8 are respectively arranged at the nylon wire reel 61 and the wire winding roller 62 to discharge the heat generated by the high-speed rotation of the nylon wire reel 61 and the wire winding roller 62. The ventilation mechanism 8 includes at least two sets of lower ventilation pipes 81 and upper ventilation pipes 82. The lower ventilation pipes 81 and the upper ventilation pipes 82 are respectively fixedly installed on the front and rear sides of the interior of the upper half cover 21. The upper and lower ends of the lower ventilation pipes 81 and the upper ventilation pipes 82 both pass through the upper half cover 21. A plug-in tube 83 for inserting the lower ventilation pipe 81 is fixedly installed on the inner wall of the lower half cover 22. The lower end of the plug-in tube 83 extends to the interior of the lower half cover 22. The lower ventilation duct 81 and the upper ventilation duct 82 are arranged alternately, and the pipe openings of the lower ventilation duct 81 and the upper ventilation duct 82 face oppositely. When the protective cover 2 is merged, the lower ventilation duct 81 is plugged into the plug-in tube 83 and communicates with the plug-in tube 83. The lower ventilation duct 81 and the upper ventilation duct 82 can promote air circulation in the areas of the upper half cover 21 and the lower half cover 22 respectively, and the lower ventilation duct 81 and the upper ventilation duct 82 are both arranged to be L-shaped, with the pipe openings facing the side. While ensuring the ventilation of the protective cover 2, it can prevent impurities from entering the protective cover 2 along the lower ventilation duct 81 and the upper ventilation duct 82, and also prevent broken wires from being thrown out from the lower ventilation duct 81 and the upper ventilation duct 82.

[0045] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by a person skilled in the art. The provision of power is also common knowledge in the art. The present invention is mainly used to protect mechanical devices, so the control method and circuit connection are not explained in detail in the present invention.
