Description

Technical Field

[0001] This utility model relates to the field of fiber yarn tension adjustment technology, specifically to a quartz fiber yarn tension adjustment device. Background Technology

[0002] Quartz fiber yarn often fails to meet industrial requirements directly after preparation and requires specific heat treatment to achieve the desired mechanical properties. During this heat treatment, the fibers shrink, generating internal tension. Improper tension control can easily lead to fiber breakage. Currently, tension adjustment devices for quartz fiber yarn commonly use manual rocker shafts for tension control. This design has room for improvement in terms of both manual operation costs and automation. Specifically, manual adjustment is not only inefficient and reliant on operator experience, but also makes it difficult to achieve real-time, precise, and stable tension control. This limits production efficiency and product performance consistency. Utility Model Content

[0003] In view of the problem that improper tension control in the mechanical structure of existing quartz fiber yarn tension adjustment devices can lead to fiber breakage, this utility model provides a quartz fiber yarn tension adjustment device, the purpose of which is to reduce the breakage rate of quartz fiber yarn during tension adjustment through mechanical structure.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A quartz fiber yarn tension adjustment device includes a base, a roller, a roller frame, a first drive motor, a pressure roller, and a pressure roller frame. The base has two sets of roller frames, each set with a roller mounted on its top. Each roller is rotatably connected to one roller frame. One end of each roller is fixedly connected to a first drive motor, and each first drive motor is fixedly connected to one roller frame. A pressure roller frame is located between the two sets of roller frames, with a pressure roller in the middle. The pressure roller is rotatably connected to the pressure roller frame. Multiple adjustment holes are provided on both sides of the pressure roller frame, arranged at equal intervals. One end of the pressure roller is inserted into one adjustment hole on one side of the pressure roller frame, and the other end is inserted into one adjustment hole on the other side of the pressure roller frame. The pressure roller is located at the bottom of the roller. Preferably, the pressure roller is provided with tension buttons at both ends, and the tension buttons and the pressure roller are provided with threads of the same pattern on their connecting surfaces. The tension buttons and the pressure roller are rotatably connected by the threads.

[0006] Preferably, both ends of the pressure roller are provided with tension buttons, which are threadedly connected to the pressure roller.

[0007] Preferably, a sliding plate is provided below the pressure roller frame. The sliding plate is inverted "U" shape. Two guide rails are provided below the sliding plate, and a guide rail base is provided below the two guide rails. Both guide rails are fixedly connected to the guide rail base. The guide rail base is rigidly connected to the base. The cross-section of the guide rail is I-shaped. One end of the sliding plate is slidably connected to one of the guide rails, and the other end of the sliding plate is slidably connected to the other guide rail. The length of the guide rail is the same as the length of the roller.

[0008] Preferably, a lead screw is provided between the two guide rails, and a rotating bearing is provided at both ends of the lead screw. One end of the lead screw is fixedly connected to one of the rotating bearings, and the other end of the lead screw is fixedly connected to the other rotating bearing. Both rotating bearings are fixed on the guide rail base. The lead screw is suspended above the top of the guide rail base. A threaded ring is fitted on the lead screw, and the threaded ring is rigidly connected to the bottom of the slide plate. The lead screw is threadedly connected to the threaded ring.

[0009] Preferably, a second drive motor is fixed on the base, the second drive motor is connected to a coupling, and the coupling is connected to the lead screw, so that the second drive motor drives the lead screw to rotate on the two rotating bearings through the coupling.

[0010] Preferably, the surface of the pressure roller is provided with a soft rubber layer, and the thickness of the soft rubber layer is 2mm.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0012] 1. The two rollers driven by the first drive motor realize the yarn feeding and taking-up functions during tension adjustment. The height of the pressure roller can be adjusted through the adjustment hole, and the resistance of the quartz fiber yarn driving the pressure roller to rotate can be adjusted through the tension knob, thus realizing the adjustable function of tension elimination for the quartz fiber yarn.

[0013] 2. The second drive motor drives the lead screw to rotate. The lead screw is covered with a threaded ring. Since the threaded ring is fixedly connected to the slide plate, it cannot rotate. However, since the slide plate is connected to the guide rail, the threaded ring takes its place and converts the force transmitted by the drive motor into a force that translates along the guide rail on the lead screw. This causes the slide plate and the pressure roller frame to be subjected to the force of the second drive motor and translate along the guide rail, thereby achieving the effect of traction of quartz fiber yarn. This realizes the fully automatic functions of yarn output, yarn take-up, and yarn traction, reducing labor costs. Attached Figure Description

Detailed Implementation

[0019] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0020] The following is combined Figures 1-3 This utility model will be described in detail.

[0021] A quartz fiber yarn tension adjusting device includes a base 1, rollers 2, roller frames 3, a first drive motor 4, pressure rollers 5, and a pressure roller frame 6. The base 1 has two sets of roller frames 3, each set having a roller 2 mounted on its top. Each roller 2 is rotatably connected to one roller frame 3. One end of each roller 2 is fixedly connected to a first drive motor 4, and each first drive motor 4 is fixedly connected to one roller frame 3. A pressure roller frame 6 is located between the two sets of roller frames 2, and a pressure roller 5 is located in the middle of the pressure roller frame 6. The pressure roller 5 is rotatably connected to the pressure roller frame 6. Multiple adjustment holes 61 are provided on both sides of the pressure roller frame 6. The multiple adjustment holes 61 on both sides of the pressure roller frame 6 are arranged at equal intervals. One end of the pressure roller 5 is inserted into one adjustment hole 61 on one side of the pressure roller frame 6, and the other end of the pressure roller 5 is inserted into one adjustment hole 61 on the other side of the pressure roller frame 6. The pressure roller 5 is located at the bottom of the roller 2. When the first drive motor 4 is running, the roller 2 on one side feeds the quartz fiber yarn through the pressure roller 5 and into the roller 2 on the other side by rotating. The height difference between the rollers 2 on both sides and the pressure roller 5 applies pressure to the surface of the quartz fiber yarn, thereby achieving the effect of eliminating tension.

[0022] Preferably, both ends of the pressure roller 5 are provided with tension knobs 62, which are threadedly connected to the pressure roller 5. The tension knobs 62 increase or decrease the gap between the pressure roller 5 and the pressure roller frame 6 by rotating on the pressure roller 5, thereby increasing or decreasing the friction force when the pressure roller 5 is rubbing, and thus adjusting the tension to be eliminated.

[0023] Preferably, a slide plate 9 is provided below the pressure roller frame 6. The slide plate 9 is inverted "U" shape. Two guide rails 8 are provided below the slide plate 9. A guide rail base 7 is provided below the two guide rails 8. Both guide rails 8 are fixedly connected to the guide rail base 7. The guide rail base 7 is rigidly connected to the base 1. The cross-section of the guide rail 8 is I-shaped. One end of the slide plate 9 is slidably connected to one guide rail 8, and the other end of the slide plate 9 is slidably connected to the other guide rail 8. The length of the guide rail 8 is the same as the length of the roller 2. The pressure roller frame 6 can be moved along the direction of the guide rail 8, so that when conveying quartz fiber yarn, the quartz fiber yarn is prevented from accumulating on one side of the take-up roller 2, and the quartz fiber yarn is evenly wound on the surface of the roller 2.

[0024] Preferably, a lead screw 10 is provided between the two guide rails 8, and a rotating bearing 11 is provided at both ends of the lead screw 10. One end of the lead screw 10 is fixedly connected to one rotating bearing 11, and the other end of the lead screw 10 is fixedly connected to the other rotating bearing 11. Both rotating bearings 11 are fixed on the guide rail base 7. The lead screw 10 is suspended above the top of the guide rail base 7. A threaded ring 12 is fitted on the lead screw 10. The threaded ring 12 is rigidly connected to the bottom of the slide plate 9. The lead screw 10 is threadedly connected to the threaded ring 12.

[0025] Preferably, a second drive motor 13 is fixed on the base. The second drive motor 13 is connected to a coupling 14, which is connected to a lead screw 10. This allows the second drive motor 13 to drive the lead screw 10 to rotate on two rotating bearings 11 via the coupling 14. When the second drive motor 13 is running, the lead screw 10 is driven to rotate. However, the threaded ring 12 on the lead screw 10 cannot rotate with the lead screw 10 because it is fixed on the non-rotating slide plate 9. This causes the threads on the lead screw 10 to press against the threads inside the threaded ring 12. The applied force causes the threaded ring 12 and the slide plate 9 to move in a translational motion along the guide rail 8, thereby causing the pressure roller 5 on the slide plate 9 to also move in a translational motion, thus realizing automated traction of quartz fiber yarn.

[0026] Preferably, the surface of the pressure roller 5 is provided with a soft rubber layer, the thickness of which is 2mm.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the technical solution of this application, and these modifications and improvements all fall within the scope of protection of this application.
