Description

Technical Field

[0001] The utility model relates to a wire clamping device used for preparing glass fiber reinforced plastic grilles. Background Art

[0002] Fiberglass reinforced plastic grating is typically manufactured by injecting glue into a mold, laying out the fibers, compacting them, heating and curing them, and then demolding them. During the laying process, the glass fibers must be secured on both sides of the mold along the laying direction to facilitate continuous laying. Conventional solutions typically address this issue by installing winding posts outside the mold. However, this not only complicates the laying mechanism's travel and affects laying efficiency, but also results in material waste due to the extra fiber winding. Utility Model Content

[0003] The purpose of the utility model is to provide a wire clamping device for preparing glass fiber reinforced plastic gratings, which can simplify the travel of the wire laying mechanism by directly clamping the two ends of the glass fiber, improve the wire laying efficiency, and avoid the entanglement waste of glass fiber material.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A wire clamping device for preparing fiberglass reinforced plastic grating, comprising a mounting seat, a first clamping block provided on the mounting seat, a second clamping block provided on the mounting seat and capable of sliding back and forth parallel to a first direction, and a driving mechanism provided on the mounting seat and configured to drive the second clamping block to slide, wherein the first clamping block and the second clamping block are arranged along the first direction;

[0006] The driving mechanism includes a connecting rod rotatably mounted on the mounting seat about a first axis, a driving cylinder for driving the connecting rod to rotate, a first rotor rotatably mounted on a push rod of the driving cylinder about its own axis, a connecting plate slidably mounted on the mounting seat in a direction parallel to the first direction and connected to the second clamping block, and a second rotor rotatably mounted on the connecting plate about its own axis; the first axis, the rotation axis of the first rotor, and the rotation axis of the second rotor are parallel to each other and perpendicular to the first direction;

[0007] The first rotor and the second rotor are each movably disposed in the connecting rod along a lengthwise extension direction of the connecting rod. The first rotor and the second rotor are respectively disposed on opposite sides of the first axis. A first distance between the rotation axis of the first rotor and the first axis is greater than a second distance between the rotation axis of the second rotor and the first axis.

[0008] The wire clamping device also includes a clamping mechanism provided on the mounting seat and used to clamp the end of the glass fiber. The clamping mechanism includes a pair of rotating arms arranged at intervals along the first direction and connected to the mounting seat rotatable around their arrangement direction, a pressure rod connected between the pair of rotating arms, and a rotating cylinder provided on the mounting seat and used to drive the rotating arms to rotate.

[0009] Preferably, one end of the connecting rod is provided with a first limiting portion for limiting the movement of the first rotor along the length direction thereof.

[0010] More preferably, the push rod is arranged below the connecting rod, and the first limiting portion is formed by one end of the connecting rod being concave toward the other end thereof.

[0011] Preferably, the other end of the connecting rod is provided with a second limiting portion for limiting the movement of the second rotor along the length direction thereof.

[0012] More preferably, the connecting plate is provided above the connecting rod, and the second limiting portion is formed by the other end of the connecting rod being concave toward one end thereof.

[0013] Preferably, the mounting seat is provided with a plurality of first clamping blocks arranged in sequence and spaced apart along the first direction, and the connecting plate is provided with a plurality of second clamping blocks arranged in sequence and spaced apart along the first direction, and the first clamping blocks and the second clamping blocks are arranged alternately in sequence along the first direction.

[0014] More preferably, the bottom of the first clamping block is concave to leave a gap for the connecting plate to slide through along the first direction.

[0015] Preferably, a first rubber strip and a second rubber strip are respectively provided on the opposite inner sides of the first clamping block and the second clamping block.

[0016] Preferably, the length of the rotating arm is adjustable.

[0017] Due to the application of the above technical solution, the present invention has the following advantages over the prior art: the wire clamping device for preparing the glass fiber reinforced plastic grating of the present invention is arranged on both sides of the mold along the wire laying direction, which has the following advantages:

[0018] By directly clamping the two ends of the glass fiber, the travel of the wiring mechanism can be simplified, the wiring efficiency can be improved, and the entanglement and waste of glass fiber materials can be avoided;

[0019] By controlling the first distance between the rotation axis of the first rotor and the first axis to be greater than the second distance between the rotation axis of the second rotor and the first axis, a larger clamping force can be obtained with a smaller driving force, thereby achieving effective clamping of the glass fiber.

[0020] By setting up a pressing mechanism to press the two ends of the cut glass fiber, it can prevent them from being turned upward by the subsequent wiring of the wiring mechanism. This not only avoids affecting the continuous wiring of the wiring mechanism, but also solves the technical problem of not being able to flatten or tighten in the subsequent pressing process.

Of course, these are merely examples and are not intended to limit the embodiments of the present invention.

[0037] See also Figure 1-2 As shown, this embodiment provides a wire clamping device for preparing glass fiber reinforced plastic grating, which is arranged on both sides of the mold along the wire laying direction, including a mounting seat 1, a first clamping block 2 arranged on the mounting seat 1, and a clamping block 2 which can be arranged in parallel with the first direction (i.e. Figure 1 A second clamping block 3 is mounted on the mounting base 1 and is slidably disposed in the direction of the arrow in the figure. A driving mechanism 4 is mounted on the mounting base 1 and is configured to drive the second clamping block 3 to slide. The first direction is perpendicular to the fiber routing direction. The first clamping block 2 and the second clamping block 3 are arranged along the first direction and cooperate with each other to clamp the end of the glass fiber.

[0038] See also Figure 3-5 As shown, the above-mentioned driving mechanism 4 includes a connecting rod 41 rotatable around a first axis on the mounting base 1, a driving cylinder 42 for driving the connecting rod 41 to rotate, a first rotor 44 rotatable around its own axis on the push rod 43 of the driving cylinder 42, a connecting plate 45 slidable back and forth along a direction parallel to the first direction on the mounting base 1 and used to connect the second clamping block 3, and a second rotor 46 rotatable around its own axis on the connecting plate 45.

[0039] The first axis, the rotation axis of the first rotor 44, and the rotation axis of the second rotor 46 are parallel to each other and perpendicular to the first direction. The extension and retraction direction of the push rod 43 is parallel to the first direction and parallel to the horizontal plane. This arrangement allows for compact installation of the drive cylinder 42, saving installation space.

[0040] In this embodiment, the mounting base 1 is provided with a plurality of first clamping blocks 2 spaced sequentially along a first direction, while the connecting plate 45 is provided with a plurality of second clamping blocks 3 spaced sequentially along the first direction. The first clamping blocks 2 and the second clamping blocks 3 are staggered along the first direction. The bottoms of the first clamping blocks 2 are recessed to provide clearance for the connecting plate 45 to slide through in the first direction. This arrangement allows for simultaneous clamping of multiple glass fibers arranged in the mold.

[0041] The first rotor 44 and the second rotor 46 are respectively movably disposed in the connecting rod 41 along the length extension direction of the connecting rod 41. The first rotor 44 and the second rotor 46 are respectively disposed on opposite sides of a first axis. A first distance between the rotation axis of the first rotor 44 and the first axis is greater than a second distance between the rotation axis of the second rotor 46 and the first axis.

[0042] With this arrangement, when the drive cylinder 42 drives the push rod 43 to extend and retract, it can drive the connecting rod 41 to rotate about the first axis through the first rotor 44, thereby driving the second rotor 46 and the connecting plate 45 to reciprocate parallel to the first direction. During this process, the distance between the first rotor 44 and the second rotor 46 relative to the first axis changes, and the first rotor 44 and the second rotor 46 rotate about their respective axis directions.

[0043] See also Figure 3 、 Figure 5 As shown, one end of the connecting rod 41 is provided with a first limiting portion 411 for limiting the movement of the first rotor 44 along its length direction, and the other end of the connecting rod 41 is provided with a second limiting portion 412 for limiting the movement of the second rotor 46 along its length direction.

[0044] In this embodiment, the push rod 43 is disposed below the connecting rod 41. The first stopper 411 is formed by a concave portion from one end of the connecting rod 41 toward the other end. The upper end surface of one end of the connecting rod 41 is closed, and the lower end surface is open. The first rotor 44 is slidably disposed therein along the length of the connecting rod 41.

[0045] In this embodiment, the connecting plate 45 is disposed above the connecting rod 41, and the second stopper 412 is formed by the other end of the connecting rod 41 being recessed inward toward one end. The other end of the connecting rod 41 passes through in the vertical direction, and the second rotor 46 is slidably disposed therein along the length of the connecting rod 41.

[0046] When the connecting rod 41 rotates, the stroke of the first rotor 44 along the length extension direction of the connecting rod 41 is greater than the stroke of the second rotor 46 along the length extension direction of the connecting rod 41 . Therefore, the recessed depth of the first limiting portion 411 is greater than the recessed depth of the second limiting portion 412 .

[0047] In this embodiment, a first rubber strip 5 and a second rubber strip 6 are respectively provided on the opposite inner sides of the first clamping block 2 and the second clamping block 3 . This arrangement enables a more secure clamping of the glass fiber.

[0048] The aforementioned wire clamping device for preparing the glass fiber reinforced plastic grating further comprises a pressing mechanism 7 provided on the mounting seat 1 and used for pressing the ends of the glass fibers.

[0049] In this embodiment, the pressing mechanism 7 includes a pair of rotating arms 71 spaced apart along a first direction and rotatably connected to the mounting base 1 about the direction of their arrangement; a pressure rod 72 connected between the pair of rotating arms 71; and a rotating cylinder 73 provided on the mounting base 1 for rotating the rotating arms 71. By providing the pressing mechanism 7 to compress the ends of the sheared glass fibers, the ends are prevented from being pulled upward by subsequent fiber laying operations of the fiber laying mechanism. This not only prevents the fiber laying mechanism from continuously laying the fibers, but also solves the technical problem of uneven flattening and tightening during the subsequent pressing process.

[0050] In this embodiment, the length of the rotating arm 71 is adjustable. As the fiber laying process continues, the glass fibers between the first clamping block 2 and the second clamping block 3 become increasingly stacked. By adjusting the length of the rotating arm 71, it is possible to ensure that the pressing mechanism 7 always presses against the ends of the cut glass fibers.

[0051] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications based on the spirit of the present invention are intended to be included in the scope of protection of the present invention.
