Description

Technical Field

[0001] This utility model relates to the field of tension balancer technology, and in particular to a multi-strand twisted tension balancer for nylon elastic yarn. Background Technology

[0002] In the production of nylon, multiple strands of nylon elastic yarn need to be twisted together using a twisting device. During the twisting process, a tension balancer is used to separate the multiple strands of nylon elastic yarn to prevent them from rubbing against each other and generating heat, thus preventing breakage and improving the stability of the twisting process. In the existing technology, the tension balancer can only adjust the tension of the multiple strands of nylon elastic yarn during the conveying process. The path of the multi-strand nylon elastic yarn after tensioning to the twisting device is not optimized. Since the multiple strands of nylon elastic yarn are in different positions but have the same destination, it is impossible to uniformly control their path during the conveying process. This makes them prone to friction with other objects and breakage, thereby reducing the production quality of nylon. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-strand twisted tension balancer for nylon elastic yarn.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a nylon elastic yarn multi-strand twisting tension balancer, including a base, a plurality of pulley positioning frames are movably connected above the base, sliding wheels are installed at both ends of the pulley positioning frames, a tensioning wheel is connected to one side of the pulley positioning frames through an adjustment mechanism, a plurality of coaxially arranged gears are installed above the base, racks are meshed on both sides of the plurality of gears, and one end of the plurality of racks is respectively connected to the plurality of pulley positioning frames.

[0005] Preferably, a gear shaft is mounted on the top of the base via a bearing, and multiple gears are fixedly sleeved on the surface of the gear shaft.

[0006] Preferably, multiple mounting slots are provided along the arcuate side of the base, and a fixed shaft is installed inside the mounting slot. The bottom end of the pulley positioning frame is movably sleeved on the surface of the fixed shaft.

[0007] Preferably, a connecting block is installed at one end of the rack, and one end of the connecting block is installed on the surface of the pulley positioning frame.

[0008] Preferably, a first helical tube is installed inside the pulley positioning frame, and an adjusting screw is installed inside the first helical tube. One end of the adjusting screw is mounted on the surface of the pulley frame of the tensioning wheel via a bearing.

[0009] Preferably, a limiting tooth block is engaged on one side of the gear mentioned above, a fixing block is installed on the side of the limiting tooth block, a fixing screw is installed through the surface of the fixing block, the bottom end of the fixing screw is installed on the top of the base, and two second screw tubes are threaded on the surface of the fixing screw, with the surfaces of the two second screw tubes contacting the top and bottom of the fixing block respectively.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] This solution involves setting multiple gears on the base, which drive multiple pulley positioning frames to move in an arc on the base via multiple racks. The pulley positioning frames drive the tension wheel and two sliding wheels to move synchronously, facilitating the conveying path of the tension wheel and two sliding adjustment nylon elastic yarns. This prevents the nylon elastic yarns from being damaged by friction with other objects during transportation, thus protecting the nylon elastic yarns and improving the production quality of nylon.

[0018] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0019] like Figure 1-5 The illustrated nylon elastic yarn multi-strand twisting tension balancer includes a base 7. Multiple pulley positioning frames 9 are movably connected to the top of the base 7. Each pulley positioning frame 9 has a sliding wheel 10 mounted at both ends. A tensioning wheel 1 is connected to one side of each pulley positioning frame 9 via an adjustment mechanism. Multiple coaxially arranged gears 2 are mounted above the base 7. Racks 4 mesh with both sides of each gear 2. One end of each rack 4 is connected to one of the pulley positioning frames 9. When guiding the multi-strand nylon elastic yarn, simply rotating the gears 2 causes them to rotate under force, driving the racks 4 to move horizontally. The racks 4 then position the multiple pulleys. When an external force is applied to the frame 9, the multiple pulley positioning frames 9 move in an arc on the surface of the fixed shaft 3 after being subjected to force. The pulley positioning frames 9 drive the tensioning wheel 1 and the two sliding wheels 10 to move synchronously, which facilitates the adjustment of the conveying path of the nylon elastic yarn by the tensioning wheel 1 and the two sliding wheels 10, and plays a protective role for the nylon elastic yarn. After the path of the nylon elastic yarn is adjusted, it is only necessary to rotate the second solenoid 14. The second solenoid 14 drives the limiting tooth block 15 to move downward into the tooth groove of the gear 2, and then fixes the position of the gear 2, thereby fixing the position of the tensioning wheel 1 and the two sliding wheels 10, which improves the stability of the multiple strands of nylon elastic yarn during the twisting process.

[0020] A gear shaft 11 is mounted on the top of the base 7 via a bearing. Multiple gears 2 are fixedly sleeved on the surface of the gear shaft 11. The gear shaft 11 can be used to install and fix multiple gears 2, which facilitates the synchronous rotation of multiple gears 2.

[0021] Multiple mounting slots 6 are provided along the arc side of the base 7. A fixed shaft 3 is installed inside the mounting slot 6. The bottom end of the pulley positioning frame 9 is movably sleeved on the surface of the fixed shaft 3. After the pulley positioning frame 9 receives the force of the rack 4, the bottom end of the pulley positioning frame 9 moves in an arc on the surface of the fixed shaft 3.

[0022] A connecting block 5 is installed at one end of the rack 4. The connecting block 5 is installed on the surface of the pulley positioning frame 9. The connecting block 5 is used to connect and fix the rack 4 and the pulley positioning frame 9, so that the rack 4 can drive the pulley positioning frame 9 to perform angle operation.

[0023] The pulley positioning frame 9 has a first helical tube 13 installed inside. An adjusting screw 12 is installed inside the thread of the first helical tube 13. One end of the adjusting screw 12 is mounted on the pulley frame surface of the tensioning wheel 1 through a bearing. When adjusting the tension of the nylon elastic yarn, simply rotate the adjusting screw 12. The adjusting screw 12 moves spirally inside the first helical tube 13, which facilitates the adjusting screw 12 to drive the tensioning wheel 1 to move the nylon elastic yarn synchronously. At this time, the two ends of the nylon elastic yarn are connected to the unwinding mechanism and the twisting equipment, respectively. The movement of the tensioning wheel 1 facilitates the tensioning of the nylon elastic yarn during the conveying process, preventing the nylon elastic yarn from tangling and knotting due to the loosening of the yarn during the conveying process, thus improving the stability of the nylon elastic yarn during the conveying process.

[0024] A limiting tooth block 15 meshes with one side of the upper gear 2. A fixing block 16 is installed on the side of the limiting tooth block 15. A fixing screw 8 is installed through the surface of the fixing block 16. The bottom end of the fixing screw 8 is installed on the top of the base 7. Two second screw tubes 14 are threaded on the surface of the fixing screw 8. The surfaces of the two second screw tubes 14 contact the top and bottom of the fixing block 16, respectively. After the angle position of the pulley positioning frame 9 is adjusted, the two second screw tubes 14 can be rotated. The second screw tubes 14 drive the fixing block 16 to move downward. The fixing block 16 drives the limiting tooth block 15 to move into the tooth groove of the gear 2, thereby fixing the position of the gear 2 and improving the stability of the position of the gear 2, thereby improving the stability of the pulley positioning frame 9 after the angle adjustment is completed.
