Description

Technical Field

[0001] This utility model belongs to the field of fiber production technology, and more specifically, it relates to a tension adjustment device for the production of special fibers. Background Technology

[0002] Specialty fibers refer to fibers with special properties or uses. Compared with ordinary fibers, they have higher strength, heat resistance, chemical corrosion resistance, electrical conductivity or other unique properties, and are widely used in fields with specific industrial needs.

[0003] The production of specialty fibers involves several steps, including solution coagulation into filaments, washing to remove solvent, drying to remove water, high-temperature heat treatment to dehydrate, and high-temperature setting. Excessive spinning speed during production can easily lead to filament breakage, so increasing the spinning speed cannot increase production capacity. Therefore, the production capacity is increased by increasing the number of parallel filament groups on the guide rollers of a single piece of equipment. When producing filaments in groups, it is necessary to ensure that the fiber quality and performance of each parallel filament group are consistent. Furthermore, when the fibers enter the heat treatment dehydration and high-temperature setting processes, they need to be dispersed by a unified guide roller so that each parallel filament group enters its respective heat treatment channel. At this time, it is necessary to balance the tension on the fibers between the channels to ensure consistent finished product quality.

[0004] Existing technologies, when balancing the tension of parallel fiber groups, lengthen the distance between the guide roller and the heat treatment channel. This results in similar lengths of the suspended portions of each fiber group, similar gravity, and thus similar tension, achieving tension balance among the fiber groups. However, this approach has a drawback: when the production equipment layout is limited by space constraints and the spacing between equipment cannot be increased, the difference in distance between the fiber groups reaching their respective heat treatment channels increases, leading to greater differences in tension values. This affects the uniformity of the finished product quality. In other words, existing special fiber production equipment struggles to balance the tension experienced by each fiber group during production in confined spaces.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] The purpose of this utility model is to provide a tension adjustment device for the production of special fibers. The technical problem to be solved is as follows: When the existing special fiber production equipment is produced in a small space, it is difficult to balance the tension of each group of fibers during separate heat treatment.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] Tension adjustment equipment for special fiber production includes a base frame. At least two rows of adjustment cylinders are detachably mounted on the top of the base frame. Each row of adjustment cylinders has a guide wheel mounted on one side. Adjustment wheel mechanisms are symmetrically mounted on both sides inside the adjustment cylinders. A force adjustment mechanism is installed between the two adjustment wheel mechanisms. Two fiber lines are mounted on the force adjustment mechanism along the direction from the adjustment wheel mechanism to the guide wheel. The adjustment wheel mechanism is used to adjust the tension value of the fiber line and to balance the tension values ​​of the two fiber lines. A tension sensor is mounted on one side of the adjustment wheel mechanism, and a main controller is mounted on one side of the base frame. Each tension sensor is electrically connected to the main controller.

[0009] As a further embodiment of this utility model: the number of adjusting cylinders installed is not less than ten, the adjusting cylinders are in two rows, and the two rows of adjusting cylinders are arranged in an alternating staggered manner.

[0010] As a further embodiment of this utility model: the adjusting wheel mechanism includes a support frame fixedly connected to the top of the adjusting cylinder. Positioning wheels are fixedly connected to both ends of one side of the support frame. A side plate is vertically fixedly connected between the side of the support frame away from the positioning wheels and the bottom of the adjusting cylinder. Two guide rails are installed on the side of the side plate near the positioning wheels. A slider is slidably connected to one side of each guide rail. A slide table is fixedly connected between the two sliders. A tension wheel is installed on one side of the slide table. A force-adjusting motor is installed on the bottom of the side plate. A screw is fixedly connected to the output end of the force-adjusting motor. The screw is threadedly connected to the inner side of the slide table. The force-adjusting motor is electrically connected to the main controller.

[0011] As a further embodiment of this utility model: the guide wheel component includes a guide wheel frame parallel to the arrangement direction of the adjustment cylinders on the adjacent side, and the top of the guide wheel frame is fitted with a guide wheel that is fixedly connected to each of the fiber lines.

[0012] As a further embodiment of this utility model: the two positioning wheels, the tension wheel, and the guide wheel are located in the same vertical plane.

[0013] As a further embodiment of this utility model: the force adjustment mechanism includes a second side plate fixedly connected to one side of the inside of the adjustment cylinder, a second guide rail fixedly connected to one side of the second side plate in the vertical direction, a second slider slidably connected to one side of the second guide rail, a balance frame installed on one side of the second slider, and two sides of one end of the balance frame fixedly connected to the tension wheel on the adjacent side respectively.

[0014] As a further embodiment of this utility model: a tension display screen is provided on one side of the tension sensor, and two fiber lines are adapted to the top of the sensor to install tension detection heads, with the fiber lines passing through the ends of the tension detection heads.

[0015] The beneficial effects of this utility model are:

[0016] By detachably installing multiple rows of adjusting cylinders on the base frame, the tension of the fiber yarn is adjusted using each adjusting cylinder as an independent tension adjustment unit, and the adjustment results are fed back to the main controller. During adjustment, the vertical displacement of the tension wheel is achieved by controlling the rotation of the force-adjusting motor of the adjusting wheel mechanism inside the adjusting cylinder. This makes the tension of the fiber yarn installed on the two positioning wheels at the top and between the tension wheels adjustable. Furthermore, the force-adjusting mechanism connects the fiber yarns on both sides of the adjusting cylinder into one unit, achieving synchronous adjustment. This ensures that the tension of the two fiber yarns inside the adjusting cylinder is consistent. In the adjustment process, the tension adjustment method of stretching each fiber yarn to a similar length and relying on their similar self-weight for tension adjustment is avoided. The tension adjustment is achieved by controlling the vertical tension of the fiber yarn in a unit adjusting cylinder through the adjusting wheel mechanism. This allows the adjusting equipment to adjust the tension of the fiber yarn in the adjusting cylinder in a smaller space, saving space while achieving uniform tension adjustment of the fiber yarn in the adjusting cylinder.

[0017] Furthermore, the regulating cylinder can be easily disassembled and replaced as an independent tension regulating unit. A tension sensor is installed inside the regulating cylinder and electrically connected to the main controller. Therefore, when performing tension regulation control in a small space, the main controller can independently control the height of the tension wheels in each regulating cylinder. The purpose is that, since the tension values ​​of the fibers in different locations within the regulating cylinder vary due to their own weight, the tension sensor displays the tension and transmits the tension value back to the main controller. Combined with the main controller's height control of the tension wheels in each easily disassembled regulating cylinder, the tension values ​​of the fibers in each regulating cylinder can be unified by controlling the different heights of the tension wheels. This achieves balanced tension regulation of a large number of fibers in a small space. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0026] like Figures 1 to 5 As shown, a tension adjustment device for the production of special fibers includes a base frame 1. Two rows of adjustment cylinders 2 are detachably installed on the top of the base frame 1. Guide rollers 3 are installed on one side of each row of adjustment cylinders 2. Adjustment roller mechanisms 4 are symmetrically installed on both sides inside the adjustment cylinders 2. A force adjustment mechanism 5 is installed between the two adjustment roller mechanisms 4 at the end away from the guide rollers 3. Two fiber lines 6 are installed along the direction from the adjustment roller mechanism 4 to the guide rollers 3 in the force adjustment mechanism 5. The adjustment roller mechanism 4 is used to adjust the tension of the fiber lines 6, and the force adjustment mechanism 5 is used to balance the tension of the two fiber lines 6. A tension sensor 7 is installed on one side of the adjustment roller mechanism 4, and a main controller 8 is installed on one side of the base frame 1. Each tension sensor 7 is electrically connected to the main controller 8.

[0027] It should be noted that four bolts 9 are installed between the bottom periphery of the regulating cylinder 2 and the base frame 1. The regulating cylinder 2 can be completely removed by removing and installing each bolt 9. Since the tension regulating device uses the regulating cylinder 2 as a tension regulating unit, when the unit fails, the regulating cylinder 2 can be disassembled and replaced with a new regulating cylinder 2 to maintain normal production. It also facilitates the repair of the faulty regulating cylinder 2, thereby ensuring production efficiency and improving the convenience of repair.

[0028] The number of regulating cylinders 2 installed is no less than ten, and the tension adjustment path of one fiber line 6 is one station, that is, no less than twenty stations can be controlled simultaneously. That is, the production capacity is increased by increasing the number of parallel stations, and the two rows of regulating cylinders 2 are arranged in an alternating staggered manner (see...). Figure 1The reason is that since the fiber lines 6 at each workstation are uniformly separated from the guide rollers of the front-end process, when the adjusting cylinders 2 are arranged alternately, the overlapping routes of each fiber line 6 can be effectively avoided to prevent interference.

[0029] The guide wheel component 3 includes a guide wheel frame 31 parallel to the arrangement direction of the adjacent side adjustment cylinder 2. The top of the guide wheel frame 31 is fitted with each fiber thread 6 and fixedly connected to the guide wheel 32. After the fiber thread 6 has completed tension adjustment inside the adjustment cylinder 2, it extends vertically upward from the bottom of the guide wheel 32 and is wound up by the subsequent take-up roller.

[0030] like Figures 2 to 3 As shown, the adjusting wheel mechanism 4 includes a support frame 41 fixedly connected to the top of the adjusting cylinder 2. Positioning wheels 42 are fixedly connected to both ends of one side of the support frame 41. A side plate 43 is fixedly connected vertically between the side of the support frame 41 away from the positioning wheels 42 and the bottom of the inner side of the adjusting cylinder 2. Two guide rails 44 are installed on the side of the side plate 43 near the positioning wheels 42. A slider 45 is slidably connected to one side of the guide rails 44. A slide table 46 is fixedly connected between the two sliders 45. A tension wheel 47 is installed on one side of the slide table 46. A force-adjusting motor 48 is installed on one side of the bottom of the side plate 43. A screw 49 is fixedly connected to the output end of the force-adjusting motor 48. The screw 49 is threadedly connected to the inner side of the slide table 46. The force-adjusting motor 48 is electrically connected to the main controller 8.

[0031] It should be noted that support seats are installed between both ends of the screw 49 and the slide table 46. The force-adjusting motor 48 is preferably a stepper motor with high positioning accuracy. The two positioning wheels 42, the tension wheel 47 at the bottom end, and the guide wheel 32 on the adjacent side at the top are located on the same vertical plane to ensure that the fiber thread 6 is not disturbed by lateral torque during tension adjustment, thereby improving the accuracy of tension adjustment.

[0032] After the fiber thread 6 is conveyed by the same guide roller to the positioning wheel 42 on one side of the support frame 41, it is then wound around the bottom end of the tension wheel 47 and passed from the other side of the tension wheel 47 to another positioning wheel 42, and finally received by the guide wheel 32. During this process, the operator can control the process via the touch screen of the main controller 8 (see...). Figure 1 The tension adjustment motor 48 is controlled to rotate, thereby adjusting the vertical movement position of the slide table 46 and the tension wheel 47 fixed thereon, thus adjusting the tension of the fiber thread 6 wound between each wheel, and can be observed through the display screen of the main controller 8. In addition, since the tension adjustment is based on each adjustment cylinder 2 as an independent unit, in order to make the tension of the fiber thread 6 inside each adjustment cylinder 2 uniform, the tension display of the tension sensor 7 inside each adjustment cylinder 2 and the rotation control of the tension adjustment motor 48 are all independent on the touch screen of the main controller 8.

[0033] like Figures 3 to 5As shown, the force adjustment mechanism 5 includes a side plate 51 fixedly connected to one side of the inside of the adjustment cylinder 2. The side plate 51 is parallel to the vertical plane of the guide wheel frame 31 on the adjacent side. A guide rail 52 is fixedly connected to one side of the side plate 51 in the vertical direction. A slider 53 is slidably connected to the guide rail 52. A balance frame 54 is installed on one side of the slider 53. The two sides of one end of the balance frame 54 are fixedly connected to the tension wheel 47 on the adjacent side, respectively.

[0034] A tension display screen 71 is provided on one side of the tension sensor 7, and two fiber lines 6 are adapted to the top to set up a tension detection head 72. The fiber lines 6 pass through the tension detection head 72 to detect tension.

[0035] It should be noted that the two force-adjusting motors 48 inside the adjusting cylinder 2 move synchronously, and during the movement, the tension wheel 47 is fixedly connected to the balance frame 54 on one side, and the slider 2 53 is slidably connected to the guide rail 2 52. When the two tension wheels 47 move, they will drive the balance frame 54 to move vertically together. At the same time, since the balance frame 54 connects the tension wheels 47 on both sides as a whole, during the tension adjustment process, the two tension wheels 47 inside the adjusting cylinder 2 always move to the same height. The tension on the fiber lines 6 on both sides can be balanced to the same value by the force-adjusting mechanism 5, and the tension value can be obtained through the tension display screen 71. The tension sensor 7 is electrically connected to the main controller 8, and the value can also be obtained from the display screen of the main controller 8. In particular, since the tension sensor 7 measures the sum of the tension on the fiber lines 6 on both sides, when the fiber line 6 is wound on only one side inside the adjusting cylinder 2, the control tension value set at the main controller 8 is half of the tension value inside the other adjusting cylinders 2. Then the tension values ​​on the two fiber lines 6 inside the adjusting cylinder 2 can be adjusted to the same state.

[0036] Furthermore, when the production space is limited, when the preceding guide roller of the production fiber line 6 distributes the fiber line 6 to each adjusting cylinder 2, due to the significant differences in the distance between the two adjusting cylinders 2 and the uniform guide roller located on one side—whether they are adjacent or centered—it is necessary to adjust the tension of the fiber line 6 inside each adjusting cylinder 2 to be consistent, in addition to maintaining the tension of the two fiber lines 6 inside each adjusting cylinder 2. This ensures the uniformity of the production quality of the batch of fiber line 6. However, due to space limitations, the distance from each fiber line 6 to each adjusting cylinder 2 varies. Therefore, the tension of each adjusting cylinder must be adjusted to be consistent. When adjusting the height of the tension wheel 47 inside the cylinder 2, it is necessary to adjust them independently according to the difference in distance from the unified guide roller. Specifically, the tension wheel 47 inside the adjusting cylinder 2 that is closer to the unified guide roller is lower, and the tension wheel 47 inside the adjusting cylinder 2 that is in the middle position is lower. That is, the fiber thread 6 inside the adjusting cylinder 2 that is closer to the unified guide roller is less affected by its own weight and has less tension. Therefore, it is necessary to increase the pulling force to balance the tension value of the fiber thread 6 that is farther away and more affected by its own weight, so as to achieve uniform tension adjustment of all fiber threads 6 in the whole batch and maintain production quality.

[0037] In addition, the special fiber used for tension adjustment in the tension adjustment equipment is polyimide fiber, which has the characteristics of high strength and high heat resistance.

However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
