Description

Technical Field

[0001] The embodiments of this utility model relate to the field of weaving machine technology, specifically to a glass fiber weaving machine with adjustable tension. Background Technology

[0002] Fiberglass roving is a plain weave fabric made of untwisted roving and is an important base material for hand lay-up fiberglass. The strength of the roving is mainly in the warp and weft directions. For applications requiring high strength in either the warp or weft, it can also be woven into a unidirectional fabric. This allows for the arrangement of more untwisted rovings in either the warp or weft, resulting in a single warp or single weft fabric.

[0003] According to a public disclosure of a fiberglass weaving machine (publication number: CN215404803U), the machine includes a weaving machine with a fixed rod fixedly connected to its bottom. A guide roller is rotatably connected to the fixed rod. An adjusting roller is slidably connected to the right side of the weaving machine. The same fiberglass filament is wound on the adjusting roller and the guide roller. A top shaft is connected to the adjusting roller. This weaving machine achieves the adjustment of the tension of the fiberglass filament through a simple structure, avoiding damage to the filament, ensuring the quality of the finished fabric, and is easy to operate and highly practical.

[0004] In the aforementioned application, the interaction between the adjusting roller and the top shaft assembly makes it difficult for the adjusting roller to achieve dynamic tension balance and stable locking when adjusting the tension. This causes the glass fiber filaments to easily rebound or shift due to vibration or load fluctuations, affecting the tension adjustment accuracy. Therefore, we propose a glass fiber weaving machine with adjustable tension. Utility Model Content

[0005] To overcome the above-mentioned defects, embodiments of this utility model provide a glass fiber weaving machine with adjustable tension, which solves the problem that the tension of the weaving machine cannot be adjusted in related technologies.

[0006] According to one aspect, at least one embodiment of the present invention provides a glass fiber weaving machine with adjustable tension, including a worktable, a support column fixedly connected to the bottom of the worktable, a foot pad fixedly connected to one end of the support column, a control plate fixedly connected to the top of the worktable, a weaving machine provided on the top of the worktable, and a fabric winding device provided on the top of the worktable.

[0007] The fabric rolling device includes a slide plate, the bottom of which is fixedly connected to the top of the workbench. A slider is slidably connected inside the slide plate, and a support plate is fixedly connected to the top of the slider. A rotating shaft sleeve is rotatably connected through the side of the support plate. A rotating shaft is rotatably connected to the inner circumferential surface of the rotating shaft sleeve, and a fabric rolling sleeve is fixedly connected to the circumferential surface of the rotating shaft. A mounting plate is fixedly connected to the side of the support plate, and a motor is fixedly connected to the side of the mounting plate. The output shaft of the motor is fixedly connected to the end of the rotating shaft away from the mounting plate. A connecting rod is fixedly connected to the side of the mounting plate, and an adjusting rack is fixedly connected to the side of the connecting rod. A fixed shaft is fixedly connected to the side of the workbench, and an adjusting gear is rotatably connected through the circumferential surface of the fixed shaft. A torsion spring shaft is rotatably connected to the side of the workbench, and a locking lug is fixedly connected to the circumferential surface of the torsion spring shaft.

[0008] For example, in at least one embodiment of the present invention, an adjustable tension glass fiber weaving machine is provided, which further includes: a buffer block fixedly connected to the inner side of the slide plate, and a rotating handle rotatably connected to the side of the adjusting gear. The buffer block reduces the impact force when the slider moves, reduces component wear, and extends the service life of the slide plate. The rotating handle directly drives the adjusting gear, simplifies the tension adjustment steps, and improves the efficiency of manual operation.

[0009] The side of the adjusting gear penetrates the circumferential surface of the rotating handle, and the circumferential surface of the fixed shaft penetrates the side of the adjusting gear. The through-type connection between the adjusting gear, the fixed shaft, and the rotating handle prevents gear misalignment or jamming and ensures transmission reliability.

[0010] The side of the buffer block is located on the displacement trajectory of the slider side, and the locking lug is located on the displacement trajectory of the adjusting gear. The buffer block restricts the slider's movement range to prevent slippage or collision, and the locking lug fixes the position of the adjusting gear to ensure that the tension is stable and does not rebound after adjustment.

[0011] The number of the slide plate, support plate and rotating shaft sleeve is set to two, and the number of the buffer block is set to four, in pairs, symmetrically arranged along the central axis of the workbench. The double slide plate and support plate are symmetrically arranged to distribute the load of the cloth rolling device and avoid unilateral deformation.

[0012] According to another aspect, at least one embodiment of the present invention also provides an adjustable tension glass fiber weaving machine, including a cutting device disposed on the top of a worktable. The cutting device includes a main board, which is fixedly connected to the top of the worktable. A feed wheel is rotatably connected to the side of the main board. A drive pulley is fixedly connected to the end of the feed wheel away from the main board. A secondary plate is fixedly connected to the top of the worktable. A drive shaft is rotatably connected to the side of the secondary plate. A driven pulley is fixedly connected to the end of the drive shaft away from the secondary plate. A transmission belt is provided on the inner side of the driven pulley. The circumferential surface of the transmission belt is connected to the circumferential surface of the driving pulley through the driven pulley. A turntable is fixedly connected to the end of the transmission shaft away from the driven pulley. A transmission rod is hinged to the side of the turntable. A cutter is hinged to the end of the transmission rod away from the turntable. A limit post is slidably connected to the side of the cutter. The cutting device is driven by the fabric winding device, which links the fabric feeding wheel, the transmission belt and the turntable, converting the rotational motion into the reciprocating cutting action of the cutter, realizing automatic fabric cutting and reducing manual intervention.

[0013] For example, in at least one embodiment of the present invention, an adjustable tension glass fiber weaving machine is provided, which further includes: a friction sleeve fixedly connected to the circumferential surface of the feeding wheel, and a friction strip fixedly connected to the circumferential surface of the friction sleeve. The friction sleeve and the friction strip increase the friction between the feeding wheel and the fabric, prevent high-hardness fabrics such as glass fiber from slipping, and ensure consistent feeding step length.

[0014] The bottom of the limiting post is fixedly connected to the top of the workbench. There are two limiting posts, cutters, and transmission rods, which are symmetrical about each other along the central axis of the workbench. The symmetrically arranged cutters, transmission rods, and limiting posts can cut both sides of the fabric at the same time, improving efficiency and avoiding unilateral force deviation.

[0015] The circumferential surface of the feed roller penetrates the side surface of the main plate, and the circumferential surface of the drive shaft penetrates the side surface of the auxiliary plate. The feed roller and drive shaft penetrate the main plate and the auxiliary plate, reducing transmission loss and improving power transmission efficiency.

[0016] The main board, sub-board, drive pulley, and driven pulley are configured in two quantities and are symmetrical about each other along the central axis of the worktable. The symmetrical layout of the main board and sub-board balances the torque and vibration during equipment operation, reduces component fatigue wear, and extends the overall lifespan.

[0017] The beneficial effects of the embodiments of this utility model are as follows:

[0018] 1. In this utility model, the fabric winding device, by rotating the handle, drives the adjusting gear to rotate. The meshing of the adjusting gear and the adjusting rack forces the connecting rod to push the mounting plate and support plate to move as a whole, thereby causing the slider to slide within the slide groove plate. This adjusts the distance between the fabric winding sleeve and the loom, thus changing the fabric tension. The buffer block absorbs impact as the slider moves, protecting the slide groove plate structure. After adjustment, the locking lug on the torsion spring shaft engages with the adjusting gear's tooth gap, preventing the adjusting gear from springing back and ensuring stable tension. The symmetrically designed double slide groove plate, support plate, and four sets of buffer blocks evenly distribute the load, avoiding unilateral deformation. This effectively solves the problem of difficulty in adjusting fabric tension in related technologies, improving the stability of the weaving process and the quality of the fabric.

[0019] 2. In this utility model, the cutting device and the fabric winding device are linked. The fabric is conveyed by the feeding wheel. The friction sleeve and friction strip on the surface of the feeding wheel prevent the fiberglass fabric from slipping, ensuring consistent feeding steps. The driving pulley and the driven pulley are connected by a transmission belt, driving the transmission shaft to rotate, which in turn drives the turntable to rotate. The turntable converts the circular motion into the reciprocating cutting action of the cutter through the transmission rod, realizing automatic fabric cutting, reducing manual intervention, and improving production efficiency. The symmetrically arranged cutter, transmission rod, and limit post cut both sides of the fabric simultaneously, further improving cutting efficiency and avoiding unilateral force offset, ensuring cutting accuracy. The symmetrical layout of the main board and sub-board balances the torque and vibration during equipment operation, reduces component fatigue wear, extends the overall life of the equipment, effectively overcomes the defects of inconvenient and inefficient fabric cutting in the prior art, realizes automated production of fiberglass fabric, and improves production efficiency and product consistency.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] like Figures 1-5 As shown, it illustrates an embodiment of the present invention of an adjustable fiberglass weaving machine, including a worktable 1, a support column 2 fixedly connected to the bottom of the worktable 1, a foot pad 3 fixedly connected to one end of the support column 2, a control plate 4 fixedly connected to the top of the worktable 1, a weaving machine 5 provided on the top of the worktable 1, and a fabric winding device 6 provided on the top of the worktable 1.

[0034] The fabric rolling device 6 includes a slide plate 601, the bottom of which is fixedly connected to the top of the workbench 1. A slider 602 is slidably connected inside the slide plate 601. A support plate 603 is fixedly connected to the top of the slider 602. A rotating bushing 604 is rotatably connected through the side of the support plate 603. A rotating shaft 605 is rotatably connected to the inner circumferential surface of the rotating bushing 604. A fabric rolling sleeve 606 is fixedly connected to the circumferential surface of the rotating shaft 605. A mounting plate 607 is fixedly connected to the side of the support plate 603. A motor 608 is fixedly connected to the side of the mounting plate 607. The output shaft of the motor 608 is fixedly connected to the end of the rotating shaft 605 away from the mounting plate 607. A connecting rod 609 is fixedly connected to the side of the mounting plate 607. An adjusting rack 610 is fixedly connected to the side of the connecting rod 609. A fixed shaft 611 is fixedly connected to the side of the worktable 1. An adjusting gear 612 is rotatably connected through the circumferential surface of the fixed shaft 611. A torsion spring shaft 613 is rotatably connected to the side of the worktable 1. A locking lug 614 is fixedly connected to the circumferential surface of the torsion spring shaft 613.

[0035] In some examples, the slide plate 601 is also fixedly connected to a buffer block 7 on its inner side, and the adjusting gear 612 is rotatably connected to a rotating handle 8 on its side. The buffer block 7 reduces the impact force when the slider 602 moves, reduces component wear, and extends the service life of the slide plate 601. The rotating handle 8 directly drives the adjusting gear 612, simplifies the tightness adjustment steps, and improves the efficiency of manual operation.

[0036] The side of the adjusting gear 612 passes through the circumferential surface of the rotating handle 8, and the circumferential surface of the fixed shaft 611 passes through the side of the adjusting gear 612. The through-type connection between the adjusting gear 612, the fixed shaft 611, and the rotating handle 8 prevents gear misalignment or jamming and ensures transmission reliability.

[0037] The side of the buffer block 7 is located on the displacement trajectory of the side of the slider 602, and the locking lug 614 is located on the displacement trajectory of the adjusting gear 612. The buffer block 7 restricts the movement range of the slider 602 to prevent slippage or collision, and the locking lug 614 fixes the position of the adjusting gear 612 to ensure that the tension is stable and does not rebound after adjustment.

[0038] There are two slide plates 601, two support plates 603 and two rotating bushings 604, and four buffer blocks 7. They are arranged in pairs and symmetrically along the central axis of the workbench 1. The double slide plates 601 and support plates 603 are symmetrically arranged to distribute the load of the cloth rolling device 6 and avoid unilateral deformation.

[0039] For example, such as Figure 1-5 As shown, the working principle of this adjustable fiberglass weaving machine is as follows: The worktable 1 serves as the base, stably supported by the support column 2 and foot pads 3. During weaving, the weaving machine 5 and the control plate 4 work together to complete fiber weaving. Subsequently, the fabric is wound up by the fabric winding device 6. The motor 608 drives the rotating shaft 605 to rotate the fabric winding sleeve 606 to wind up the fabric. The tension adjustment is achieved through a linkage mechanism. Turning the handle 8 drives the adjusting gear 612 to rotate. The adjusting gear 612 meshes with the adjusting rack 610, forcing the connecting rod 609 to push the mounting plate 607 and... The support plate 603 moves as a whole, causing the slider 602 to slide within the slide plate 601, thereby adjusting the distance between the fabric roll sleeve 606 and the loom 5, changing the fabric tension. The buffer block 7 absorbs the impact when the slider 602 moves, protecting the structure of the slide plate 601. After adjustment, the locking lug 614 on the torsion spring shaft 613 engages with the tooth gap of the adjusting gear 612 to prevent the adjusting gear 612 from springing back, ensuring stable tension. The symmetrically designed double slide plate 601, support plate 603, and four sets of buffer blocks 7 evenly distribute the load, avoiding unilateral deformation.

[0040] like Figures 1-5As shown, this illustrates another embodiment of the present invention: an adjustable tension glass fiber weaving machine. It is largely the same as the technical solution described above, so only the differences are emphasized. A cutting device 9 is provided on the top of the workbench 1. The cutting device 9 includes a main board 901, which is fixedly connected to the top of the workbench 1. A feed roller 902 is rotatably connected to the side of the main board 901. A drive pulley 903 is fixedly connected to the end of the feed roller 902 away from the main board 901. A secondary plate 904 is fixedly connected to the top of the workbench 1. A transmission shaft 905 is rotatably connected to the side of the secondary plate 904. A driven pulley 906 is fixedly connected to the end of the transmission shaft 905 away from the secondary plate 904. A transmission belt 907 is provided on the inner side of the driven pulley 906. The circumferential surface of the transmission belt 907 is connected to the circumferential surface of the driving pulley 903 through the driven pulley 906. A turntable 908 is fixedly connected to the end of the transmission shaft 905 away from the driven pulley 906. A transmission rod 909 is hinged to the side of the turntable 908. A cutter 910 is hinged to the end of the transmission rod 909 away from the turntable 908. A limit post 911 is slidably connected to the side of the cutter 910. The cutting device 9 is driven by the fabric winding device 6, which makes the fabric feeding wheel 902, the transmission belt 907 and the turntable 908 work together to convert the rotational motion into the reciprocating cutting action of the cutter 910, thereby realizing automatic fabric cutting and reducing manual intervention.

[0041] In some examples, the following are also included: a friction sleeve 10 is fixedly connected to the circumferential surface of the feed roller 902, and a friction strip 11 is fixedly connected to the circumferential surface of the friction sleeve 10. The friction sleeve 10 and the friction strip 11 increase the friction between the feed roller 902 and the fabric, prevent high-hardness fabrics such as fiberglass from slipping, and ensure consistent feed step length.

[0042] The bottom of the limiting post 911 is fixedly connected to the top of the worktable 1. There are two limiting posts 911, cutters 910 and transmission rods 909, which are symmetrical about each other along the central axis of the worktable 1. The symmetrically arranged cutters 910, transmission rods 909 and limiting posts 911 can cut both sides of the fabric at the same time, improving efficiency and avoiding unilateral force deviation.

[0043] The circumferential surface of the feed roller 902 penetrates the side of the main board 901, and the circumferential surface of the drive shaft 905 penetrates the side of the auxiliary board 904. The feed roller 902 and the drive shaft 905 penetrate the main board 901 and the auxiliary board 904, reducing transmission loss and improving power transmission efficiency.

[0044] There are two main board 901, secondary board 904, drive pulley 903 and driven pulley 906, which are symmetrical about each other along the central axis of the worktable 1. The symmetrical layout of main board 901 and secondary board 904 balances the torque and vibration during the operation of the equipment, reduces component fatigue wear, and extends the overall life.

[0045] For example, such as Figures 1-5As shown, the fabric winding device 6 synchronously drives the cutting device 9 when winding the fabric. The fabric is stably conveyed through the friction sleeve 10 and friction strip 11 set on the surface of the feed roller 902 to prevent the glass fiber from slipping. The feed roller 902 drives the drive pulley 903 to rotate, and transmits the power to the driven pulley 906 through the transmission belt 907, driving the transmission shaft 905 to rotate, which in turn drives the turntable 908 to rotate. The turntable 908 converts the circular motion into linear reciprocating motion through the hinged transmission rod 909, pushing the two symmetrically distributed cutters 910 to synchronously cut the waste material on both sides of the fabric along the sliding trajectory of the limit post 911. The limit post 911 is fixed to the top of the worktable 1 to ensure the linear motion accuracy of the cutter 910. The symmetrically designed double main plate 901, secondary plate 904, drive pulley 903, and driven pulley 906 balance the transmission torque and reduce vibration and component wear.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
