Description

Technical Field

[0001] This utility model belongs to the field of quartz fiber yarn frame technology, and particularly relates to a quartz fiber yarn frame with automatically adjustable tension. Background Technology

[0002] Quartz fiber yarn racks are core equipment in quartz fiber production lines, mainly used to support the yarn bobbin and ensure stable separation and transmission of fiber filaments during processing. Existing quartz fiber yarn racks require adjustment of the yarn bobbin's rotation speed during use. During this adjustment, issues arise such as excessively rapid speed changes and sudden tension changes in the quartz fiber yarn when rotating in the opposite direction, leading to yarn breakage or knotting. Furthermore, incomplete bobbin positioning can cause relative slippage, affecting the stability of quartz fiber yarn tension adjustment. Utility Model Content

[0003] This invention addresses the problems of sudden tension changes in quartz fiber yarn and relative slippage caused by incomplete positioning of the quartz fiber yarn bobbin in existing technologies, and proposes the following technical solution: An automatically tension-adjustable quartz fiber yarn frame, comprising: Base frame; The main shaft is rotatably connected to the inner surface of the base frame, and an auxiliary component is slidably connected to the outer surface of the main shaft. A limit component is fixedly connected to one end of the auxiliary component away from the base frame. A CNC motor is fixedly connected to the outer surface of the middle part of the base frame, and the output end of the CNC motor is fixedly connected to the end of the main spindle away from the auxiliary components.

[0004] As a preferred embodiment of the above technical solution, the auxiliary component includes: The inner sleeve is slidably connected to the outer surface of the main shaft. A rib is fixedly connected to the outer surface of the inner sleeve, and a flexible roller is rotatably connected to the end of the rib away from the inner sleeve.

[0005] As a preferred embodiment of the above technical solution, the auxiliary component further includes: An outer sleeve abuts against the outer surface of a flexible roller one. A rib plate two is fixedly connected to the inner surface of the outer sleeve. A flexible roller two is fixedly connected to one end of the rib plate two away from the outer sleeve. The outer surface of the flexible roller two abuts against the outer surface of the inner sleeve. An arc-shaped shock absorber is fixedly connected between adjacent rib plate one and rib plate two.

[0006] As a preferred embodiment of the above technical solution, the limiting component includes: A guide rod is fixedly connected to the inner surface of the outer sleeve at the end away from the base frame, and a triangular middle block is fixedly connected to the other end of the guide rod; An arc-shaped frame is slidably connected to the outer surface of the guide rod. A retaining strip is fixedly connected to one end of the arc-shaped frame away from the middle block of the triangle. The outer surface of the retaining strip is slidably connected to the inner surface of the outer sleeve.

[0007] As a preferred embodiment of the above technical solution, the limiting component includes: Lateral shock absorbers are fixedly connected between the opposite surfaces of adjacent arc-shaped frames; A side plate frame is fixedly connected to the end of the triangular middle block away from the main axis. A threaded rod is rotatably connected to the inner surface of the side plate frame. A knob is fixedly connected to the end of the threaded rod near the side plate frame. The outer surface of the threaded rod is threadedly connected to the inner surface of one of the arc-shaped frames. The protective shell is fixedly connected to the other end of the side panel frame, and the outer surface of the protective shell is snapped into the outer surface of the outer sleeve.

[0008] As a preferred embodiment of the above technical solution, it also includes: A splitter frame is fixedly connected to the outer surface of the right end of the base frame, and the splitter frame is provided with several splitter holes; A tension sensor is fixedly connected to the inner surface of the dividing hole, and the tension sensor is electrically connected to the CNC motor.

[0009] The beneficial effects of this utility model are as follows: By incorporating an arc-shaped shock absorber, when the CNC motor drives the inner sleeve to rotate in the opposite direction or decelerate, the change in the inner sleeve's rotational speed is delayed and smoothly transmitted to the outer sleeve. This prevents the quartz fiber yarn from breaking or knotting due to excessive speed changes in the CNC motor, thus improving overall reliability and stability. Furthermore, the inclusion of flexible rollers one and two prevents direct contact between the inner and outer sleeves, reducing the coefficient of friction and ensuring smooth rotation. The flexible rollers one and two are made of flexible materials, further reducing vibration between the inner and outer sleeves during speed changes, thus improving overall service life and practicality. Turning the knob rotates the threaded rod, which, through the threaded transmission between the threaded rod and the arc-shaped frame, moves the clamping strip within the limit of the outer sleeve, thus facilitating the clamping of the quartz fiber yarn bobbin. Simultaneously, the linkage formed by the arc-shaped frame and the lateral shock absorbers ensures synchronized movement of each arc-shaped frame, distributing the impact on the clamping strip during rotation to the respective lateral shock absorbers, improving overall stability and practicality. Furthermore, the outer surface of the clamping strip is made of flexible material, while the interior contains counterweight material. As the inner and outer sleeves rotate, the inertia of the clamping strip provides additional pressure; the faster the rotation speed, the tighter the clamping of the quartz fiber yarn bobbin, preventing relative slippage between the outer sleeve and the quartz fiber yarn bobbin during rotation, thus improving overall safety and reliability.

[0012] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0013] Example 1 This invention provides a quartz fiber yarn frame with automatically adjustable tension, such as... Figures 1 to 7As shown, the system includes a base frame 1, a main spindle 2 rotatably connected to the inner surface of the base frame 1, an auxiliary component 3 slidably connected to the outer surface of the main spindle 2, a limit component 4 fixedly connected to one end of the auxiliary component 3 away from the base frame 1, a CNC motor 5 fixedly connected to the outer surface of the middle part of the base frame 1, and the output end of the CNC motor 5 fixedly connected to one end of the main spindle 2 away from the auxiliary component 3. The auxiliary component 3 includes an inner sleeve 301 slidably connected to the outer surface of the main spindle 2, a rib 302 fixedly connected to the outer surface of the inner sleeve 301, and a flexible roller 303 rotatably connected to one end of the rib 302 away from the inner sleeve 301. The outer surface of the flexible roller 303 abuts against a... An outer sleeve 304 has a rib plate 305 fixedly connected to its inner surface. A flexible roller 306 is fixedly connected to one end of the rib plate 305 away from the outer sleeve 304. The outer surface of the flexible roller 306 abuts against the outer surface of the inner sleeve 301. An arc-shaped shock absorber 307 is fixedly connected between adjacent rib plates 302 and 305. A limit component 4 is fixedly connected to one end of the auxiliary component 3 away from the base frame 1. A CNC motor 5 is fixedly connected to the outer surface of the middle part of the base frame 1. The output end of the CNC motor 5 is fixedly connected to one end of the spindle 2 away from the auxiliary component 3. A wire divider 6 is fixedly connected to the outer surface of the right end of the base frame 1. The wire distribution frame 6 has several wire distribution holes, and tension sensors 7 are fixedly connected to the inner surface of the wire distribution holes. Tension sensors 7 are industrial instruments that measure tension by detecting material deformation or displacement. They are mainly divided into two technical routes: strain gauge type and micro-displacement type. They are made of metal materials and output analog signals. The tension sensors 7 are electrically connected to the CNC motor 5. Each tension sensor 7 corresponds to one of the quartz fiber yarns, and performs tension detection on each quartz fiber yarn. When the tension is inconsistent with the predetermined tension, the speed of the CNC motor 5 is adjusted. An arc-shaped shock absorber 307 is provided to ensure that the inner sleeve 301 rotates in the opposite direction or decelerates when the CNC motor 5 is started. The rotational speed change of the inner sleeve 301 is delayed and smoothly transmitted to the outer sleeve 304, avoiding sudden excessive speed changes of the CNC motor 5 that could cause the quartz fiber yarn to break or knot, thus improving overall reliability and stability. At the same time, by setting flexible roller 1 303 and flexible roller 2 306, direct contact between the inner sleeve 301 and the outer sleeve 304 is avoided, which can reduce the coefficient of friction between the inner sleeve 301 and the outer sleeve 304 and ensure smooth rotation between the inner sleeve 301 and the outer sleeve 304. Furthermore, the flexible roller 2 306 and flexible roller 1 303 are made of flexible materials, which can reduce the vibration between the inner sleeve 301 and the outer sleeve 304 during speed changes, thus improving the overall service life and practicality.

[0014] like Figures 1 to 7As shown, the limiting component 4 includes a guide rod 401 fixedly connected to the inner surface of the outer sleeve 304 away from the base frame 1. A triangular intermediate block 402 is fixedly connected to the other end of the guide rod 401. An arc-shaped frame 403 is slidably connected to the outer surface of the guide rod 401. A retaining strip 404 is fixedly connected to the end of the arc-shaped frame 403 away from the triangular intermediate block 402. The outer surface of the retaining strip 404 is slidably connected to the inner surface of the outer sleeve 304. The guide rod 401 can guide the arc-shaped frame 403, ensuring... The sliding stability of the arc-shaped frame 403 and the retaining strip 404 is ensured. A lateral shock absorber 405 is fixedly connected between the opposing surfaces of adjacent arc-shaped frames 403. A side plate frame 406 is fixedly connected to one end of the triangular intermediate block 402 away from the main shaft 2. A threaded rod 407 is rotatably connected to the inner surface of the side plate frame 406. A knob 408 is fixedly connected to one end of the threaded rod 407 near the side plate frame 406. The outer surface of the threaded rod 407 is threadedly connected to the inner surface of one of the arc-shaped frames 403. The other end of the side plate frame 406 is fixed... A protective outer shell 409 is fixedly connected, and the outer surface of the protective outer shell 409 engages with the outer surface of the outer sleeve 304. The protective outer shell 409 can protect the internal parts of the limiting component 4. Turning the knob 408 drives the threaded rod 407 to rotate. Through the threaded transmission between the threaded rod 407 and the arc-shaped frame 403, the clamping strip 404 can be moved under the limitation of the outer sleeve 304, thereby facilitating the clamping of the quartz fiber yarn bobbin. At the same time, through the linkage formed by the arc-shaped frame 403 and the lateral shock absorber 405, the various components can be secured. The arc-shaped frame 403 moves synchronously, dispersing the impact of the clamping strip 404 during rotation to each lateral shock absorber 405, improving overall stability and practicality. Meanwhile, the outer surface of the clamping strip 404 is made of flexible material, and the inside is a counterweight material. When the inner sleeve 301 and the outer sleeve 304 rotate, the inertia of the clamping strip 404 provides additional pressure. That is, the faster the rotation speed, the tighter the clamping of the quartz fiber yarn bobbin, preventing relative slippage between the outer sleeve 304 and the quartz fiber yarn bobbin during rotation, thus improving overall safety and reliability.

[0015] Working principle: The quartz fiber yarn bobbin is fitted onto auxiliary component 3. Turning knob 408 rotates the threaded rod 407. Through the threaded transmission between the threaded rod 407 and the arc-shaped frame 403, the clamping strip 404 moves under the limit of the outer sleeve 304, thus facilitating the clamping of the quartz fiber yarn bobbin. The outer surface of the clamping strip 404 is made of flexible material, while the interior contains counterweight material. When the inner sleeve 301 and outer sleeve 304 rotate, the inertia of the clamping strip 404 provides additional pressure, preventing relative slippage between the outer sleeve 304 and the quartz fiber yarn bobbin during rotation, improving overall safety and reliability. Tension sensor 7 detects the tension on the quartz fiber yarn. Based on changes in tension, the speed of CNC motor 5 is adjusted. An arc-shaped shock absorber 307 ensures a delay in the speed change of the inner sleeve 301 when the CNC motor 5 drives the inner sleeve 301 to rotate in the opposite direction or decelerate. Furthermore, the rotation is smoothly transmitted to the outer sleeve 304, preventing the quartz fiber yarn from breaking or knotting due to excessive speed changes in the CNC motor 5, thus improving overall reliability and stability. Simultaneously, the flexible rollers 303 and 306 prevent direct contact between the inner sleeve 301 and the outer sleeve 304, reducing the coefficient of friction and ensuring smooth rotation. The flexible rollers 306 and 303, made of flexible materials, reduce vibrations between the inner sleeve 301 and the outer sleeve 304 during speed changes, improving overall service life and practicality. Additionally, the linkage formed by the arc-shaped frame 403 and the lateral shock absorbers 405 ensures synchronous movement of each arc-shaped frame 403, distributing the impact on the clamping strip 404 during rotation to the lateral shock absorbers 405, further enhancing overall stability and practicality.
