Description

Technical Field

[0001] The invention relates to the technical field of glass fiber processing equipment, and in particular to a glass fiber tensioner with adjustable tension. Background Art

[0002] Glass fiber cloth is a plain fabric of untwisted coarse yarn and is an important base material for hand-laid FRP. The strength of the woven cloth is mainly in the warp and weft directions of the fabric. For occasions requiring high strength in the warp or weft directions, it can also be woven into a unidirectional cloth, which can arrange more untwisted coarse yarns, single warp cloth, and single weft cloth in the warp or weft directions. In the process of weaving glass fiber cloth, in order to adjust the tension of the glass fiber during feeding, so as to improve the production quality of the product and make its density and tightness more uniform, a tensioner is usually required.

[0003] During the rotation of the rotating plate of the tensioner, the path and tortuosity of the yarn are changed, thereby changing the size of the yarn tension; the rotating plate used on the existing glass fiber cloth tensioner is usually a purchased finished product. Due to its size, spatial position and structural strength, the rotating plate can only swing within a certain range during the rotation, and the swing amplitude is not large enough to adapt to the adjustment of tension in a larger range. If the glass fiber is too loose, the rotating plate still cannot completely straighten the glass fiber after it is rotated to the maximum angle. The tension on the glass fiber is often too loose or too tight, resulting in unstable product quality; and the current wire outlet direction of the tensioner is not adjustable, the wire outlet direction is relatively single, and multi-angle wire outlet cannot be achieved. Summary of the invention

[0004] The object of the present invention is to provide a glass fiber tensioner with adjustable tension, which can adjust the position of a fixed winding column on the tensioner, so that the tension adjustment range of the tensioner can be adjusted in a larger range, and the outlet direction of the tensioner can be adjusted.

[0005] The present invention comprises a mounting plate, an adjusting plate and a rotating plate which are sequentially installed from bottom to top; a first fixed winding column and a second fixed winding column are fixedly installed on the adjusting plate, and the first fixed winding column and the second fixed winding column are symmetrically arranged on the left and right sides of the adjusting plate; an inlet plate, a first rotating winding column, a second rotating winding column, a third rotating winding column and an outlet plate are sequentially installed on the rotating plate from left to right, and an inlet hole and an outlet hole are respectively provided on the inlet plate and the outlet plate; a rotating shaft is provided in the middle of the rotating plate, a through hole is provided in the middle of the adjusting plate, the upper part of the rotating shaft passes through the center of the through hole and is fixedly connected to the rotating plate, and the lower part of the rotating shaft is rotatably connected to the mounting plate.

[0006] Preferably, the rotating plate is in a straight line shape, and a "U"-shaped avoidance opening is provided on the rotating plate at the first fixed winding column and the second fixed winding column, and the openings of the two avoidance openings face opposite directions; the wire inlet plate and the first rotating winding column are respectively arranged on the left and right sides of the first fixed winding column, and the second rotating winding column and the third rotating winding are respectively arranged on the left and right sides of the second fixed winding column.

[0007] Preferably, the adjustment plate includes an outer plate located on the outside and an inner plate arranged in the center of the outer plate, the lower part of the inner plate is fixed above the mounting plate, and the through hole is arranged in the center of the inner plate; the inner plate is circular, and the outer plate is rotatably connected to the outside of the inner plate.

[0008] Preferably, the adjustment plate is circular, and a sawtooth is provided on an outer edge of one side of the adjustment plate. The sawtooth is arranged in an arc shape on the circumference of the adjustment plate with the center of the adjustment plate as the center of the circle.

[0009] Preferably, scale lines are provided on the adjustment plate at positions corresponding to the saw teeth.

[0010] Preferably, a locking device is fixedly installed on the mounting plate, located on the sawtooth side, and the locking device includes a mounting seat, a swing arm is rotatably connected to the mounting seat, an arc plate is fixedly connected to the end of the swing arm, and a locking tooth is fixedly installed on the end of the arc plate, and the locking tooth is meshed with the sawtooth to achieve locking of the adjustment plate.

[0011] Preferably, a handle is fixedly connected to the adjustment plate.

[0012] In summary, the present invention has the following beneficial effects:

[0013] 1. The fixed winding posts are set on the adjustment plate. The adjustment plate can be rotated to stagger the staggered angle between the two fixed winding posts, so as to adjust the adjustment range of the tension of the tensioner. The greater the staggered angle between the two fixed winding posts, the more the rotating plate on the tensioner tilts. After the glass fiber enters the tensioner from the fixed feed direction, its tortuosity is greater and the path it passes is longer, which is suitable for adjusting the tension of loose glass fibers. Conversely, it can adapt to the adjustment of tight glass fibers, so as to meet the weaving requirements of glass fibers with various degrees of tightness, thereby improving the quality of weaving products;

[0014] 2. In addition to adjusting the tension over a wide range, the final wire outlet angle of the tensioner can also be adjusted by adjusting the relative position between the fixed winding columns. The wire outlet direction of the tensioner can be adjusted within a range of up to 90 degrees to meet different weaving requirements;

[0015] 3. A locking device is provided on the side of the adjustment plate, and the locking teeth mesh with the saw teeth to lock the adjustment plate and prevent it from rotating; the arc plate is arranged concentrically with the adjustment plate, and the diameter of the arc plate is adapted to the diameter of the adjustment plate, so that after the adjustment plate rotates a certain angle, the locking teeth and the saw teeth can still mesh; a semicircular shaft penetrating the swing arm is installed on the swing arm, and locking rings are connected to the front and rear ends of the semicircular shaft. A lock buckle is provided on the rear side of the mounting seat, and the lock ring is buckled in the lock buckle to lock the swing arm. In normal use, the adjustment plate will not rotate, thereby not affecting the use;

[0016] 4. On the adjustment plate, there are scale lines at the corresponding positions of the saw teeth. The middle reading of the scale lines is 0, and the interval between adjacent scale lines is adapted to the interval between the saw teeth. On the arc plate, the locking teeth in the middle are painted with colors as marks. When the colored locking teeth are aligned with a certain scale, it represents the scale adjusted by the adjustment plate, so that the adjusted scale can be quantified and the adjustment is more precise, without relying on the operator's experience.

DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with the accompanying drawings.

[0026] The orientations mentioned in this specification are based on the orientations of the glass fiber tensioner with adjustable tension of the present invention when it is working normally, and do not limit the orientations during storage and transportation. They only represent relative positional relationships, not absolute positional relationships.

[0027] like Figures 1 to 7 As shown together, a tension-adjustable glass fiber tensioner comprises a mounting plate 1, an adjusting plate 2 and a rotating plate 3 which are sequentially installed from bottom to top; a first fixed winding column 204 and a second fixed winding column 205 are fixedly installed on the adjusting plate 2, and the first fixed winding column 204 and the second fixed winding column 205 are symmetrically arranged on the left and right sides of the adjusting plate 2; an inlet plate 301, a first rotating winding column 302, a second rotating winding column 303, a third rotating winding column 304 and an outlet plate 305 are sequentially installed on the rotating plate 3 from left to right, and an inlet hole and an outlet hole are respectively provided on the inlet plate 301 and the outlet plate 305.

[0028] The rotating plate 3 is in a straight line shape. On the rotating plate 3, a "U"-shaped avoidance opening 306 is provided at the first fixed winding column 204 and the second fixed winding column 205. The openings of the two avoidance openings 306 face opposite directions. When the rotating shaft 4 rotates, the avoidance opening 306 can avoid the positions of the first fixed winding column 204 and the second fixed winding column 205, so that the first fixed winding column 204 and the second fixed winding column 205 can enter and exit at the avoidance opening 306.

[0029] The wire feed plate 301 and the first rotating winding column 302 are respectively arranged on the left and right sides of the first fixed winding column 204, and the second rotating winding column 303 and the third rotating winding column are respectively arranged on the left and right sides of the second fixed winding column 205; the winding direction of the glass fiber yarn 6 is the wire feed plate 301, the first fixed winding column 204, the first rotating winding column 302, the second rotating winding column 303, the second fixed winding column 205, the third rotating winding column 30 4 and the outlet plate 305, the glass fiber yarn 6 is interlaced and wound back and forth between the winding pillars in an approximately straight line shape; the rotating plate 3 rotates around the rotating shaft 4, so that the rotation directions of the inlet plate 301, the first rotating winding pillar 302 and the second rotating winding pillar 303 and the third rotating winding pillar 304 are opposite, and finally the rotating winding pillars on the left and right sides of the rotating shaft 4 are staggered at opposite angles, which changes the path and tortuosity of the yarn, thereby changing the tension of the yarn.

[0030] A rotating shaft 4 is provided in the middle of the rotating plate 3, a through hole 203 is provided in the middle of the adjusting plate 2, the upper part of the rotating shaft 4 passes through the center of the through hole 203 and is fixedly connected to the rotating plate 3, the lower part of the rotating shaft 4 is rotatably connected to the mounting plate 1 through a bearing 7, the lower part of the rotating shaft 4 continues to extend downward into the damping oil barrel below the mounting plate 1, and a damping blade is connected to the end of the rotating shaft 4, the damping blade is immersed in the damping oil, and a reset spring is also installed on the rotating shaft 4; the glass fiber filament 6 is wound between the winding columns, and due to the change of its tension, it drives the rotating plate 3 to swing back and forth, so that the distance between the fixed winding column and the rotating winding column is staggered, thereby realizing the glass fiber filament 6. Adjustment of tension; when the length of the glass fiber yarn 6 is tightened, the tension on the glass fiber yarn 6 increases, and the offset distance between the fixed winding column and the rotating winding column decreases, wherein the damping blades immersed in the damping oil have a certain resistance to the rotating shaft 4, so that the rotating plate 3 rotates at a slower speed; when the length of the glass fiber yarn 6 becomes longer, the tension on the glass fiber yarn 6 becomes smaller, and under the action of the reset spring, the offset distance between the fixed winding column and the rotating winding column increases; the rotating plate 3 swings back and forth to adjust the tension on the glass fiber yarn 6, thereby adapting to the weaving speed and improving the quality of the weaving product. This technology is a prior art and is not explained in detail in this application.

[0031] The adjustment plate 2 includes an outer plate 201 located on the outside, and an inner plate 202 arranged at the center of the outer plate 201. The lower part of the inner plate 202 is fixed above the mounting plate 1. The through hole 203 in the middle of the adjustment plate 2 is arranged at the center of the inner plate 202. The rotating shaft 4 passes through the through hole 203 and does not contact the through hole 203, so that the rotation of the rotating shaft 4 does not affect the position of the adjustment plate 2; the inner plate 202 is circular, and the outer plate 201 is rotatably connected to the outside of the inner plate 202 and can rotate around the inner plate 202.

[0032] The adjustment plate 2 can be any shape that is symmetrical on the left and right, and the fixed winding columns can be symmetrically arranged on the left and right sides of its symmetry axis, so that when the adjustment plate is rotated, the two fixed winding columns always rotate in a circle with the center of the adjustment plate 2 as the center; preferably, in this embodiment, the adjustment plate 2 is circular, and a sawtooth 206 is provided on the outer edge of one side of the adjustment plate 2, and the sawtooth 206 is arranged in an arc shape on the circumference of the adjustment plate 2 with the center of the adjustment plate 2 as the center of the circle.

[0033] A locking device 5 is fixedly installed on the mounting plate 1, located on the side of the sawtooth 206. The locking device 5 includes a mounting seat 501, and a swing arm 502 is rotatably connected to the mounting seat 501. The swing arm 502 can rotate around the mounting seat 501; an arc plate 503 is fixedly connected to the end of the swing arm 502, and a locking tooth 504 is fixedly installed on the end of the arc plate 503. The locking tooth 504 meshes with the sawtooth 206 to lock the adjustment plate 2 and prevent it from rotating; the arc plate 5 03 is arranged cocentrically with the adjustment plate, and the diameter of the arc plate 503 is adapted to the diameter of the adjustment plate, so that after the adjustment plate is rotated by a certain angle, the locking tooth 504 and the serration 206 can still engage; a semicircular shaft 507 penetrating the swing arm 502 is installed on the swing arm 502, and locking rings 505 are connected to the front and rear ends of the semicircular shaft 507, and a locking buckle 506 is provided on the rear side of the mounting seat 501, and the locking ring 505 is buckled in the locking buckle 506 to achieve locking of the swing arm 502.

[0034] On the adjustment plate 2, at the corresponding position of the sawtooth 206, there is a scale line 207, the middle reading of the scale line 207 is 0, and the interval between adjacent scale lines 207 is adapted to the interval between the sawtooth 206; on the arc plate 503, the locking tooth 504 located in the middle thereof is painted with color as a mark, and when the colored locking tooth 504 is aligned with a certain scale, it represents the scale adjusted by the adjustment plate 2.

[0035] Furthermore, a handle 208 is fixedly connected to the adjustment plate 2 to facilitate the rotation of the adjustment plate 2 .

[0036] When the current rotation range of the rotating plate 3 is not enough to adjust the tension of the glass fiber yarn 6, it is necessary to adjust the adjusting plate 2 to appropriately stagger the relative positions between the fixed winding columns; first, the locking ring 505 and the locking buckle 506 are opened to allow the swing arm 502 to move, and then the swing arm 502 is rotated to separate the sawtooth 206 from the locking tooth 504. At this time, the outer plate 201 of the adjustment plate can rotate around its inner plate 202, and the handle 208 is held to rotate the adjustment plate. According to the needs, it is rotated to a certain angle so that the locking tooth 504 with the color mark on the arc plate 503 is aligned with the corresponding scale on the adjustment plate; at this time, the first fixed winding column 204 on the adjustment plate The second fixed winding column 205 rotates around the center of the adjustment plate at the same time, so as to achieve a certain distance between the two, and the rotation trajectories of the two are always on a circle concentric with the center of the adjustment plate; at the same time, the rotating plate 3 also needs to rotate at a certain angle to adapt to the change in position between the fixed winding columns caused by the rotation of the adjustment plate. Since the center of the rotating plate 3 coincides with that of the adjustment plate, after its rotation, the relative position of the fixed winding column and the avoidance opening 306 remains unchanged. During subsequent use, there will be no interference between the fixed winding column and the rotating plate 3; after the adjustment is completed, bend down the swing arm 502, and then lock the locking ring 505 to complete the adjustment of the adjustment plate.

[0037] At the same time, when a fiber cloth with higher weaving requirements or a pattern with more complex structure needs to be weaved, it is necessary to enter the wire from multiple angles. The above method can also be used to adjust the relative position between the fixed winding columns to adjust the final wire outlet angle of the tensioner. The wire outlet direction of the tensioner can be adjusted within a range of up to 90 degrees to adapt to different weaving requirements without the need to add additional winding plates to change the direction of the glass fiber yarn 6. Because the toughness of the glass fiber yarn 6 is not good, the more winding plates there are, the greater the turning angle of the glass fiber yarn 6, the greater the possibility of the glass fiber yarn 6 breaking, and the lower the work efficiency; when the position of the back-end equipment changes, this method can also be used to adjust the wire outlet direction to adapt to the wire entry angle requirements of the equipment, thereby avoiding the need for the installation position of the tensioner and increasing the workload.

[0038] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
