[0025] The purpose of the present invention is to provide a glass fiber continuous mat laying device to solve the problems existing in the above-mentioned prior art and improve the molding quality and efficiency of the glass fiber continuous mat.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] In the glass fiber continuous mat laying device provided by the present invention, the active roller 3 and the first lower driven roller 32 are connected by a first transmission belt 36, and the upper driven roller 4 and the second lower driven roller 33 are connected by a second transmission belt 37. In the process of laying the glass fiber continuous mat, the glass fiber filaments 41 are firstly made to enter the gap between the first transmission belt 36 and the top of the second transmission belt 37, and then the slider driving device 5 is controlled to drive the first slider 30 to approach the first bracket 8. The stroke of the first slider 30 is 10-20 mm. Figure 4As shown, the top of the first transmission belt 36 contacts the top of the second transmission belt 37. After the roller driving device is turned on, due to the friction between the first transmission belt 36 and the second transmission belt 37, the friction between the first transmission belt 36 and the active roller 3 and the first lower driven roller 32, and the friction between the second transmission belt 37 and the upper driven roller 4 and the second lower driven roller 33, the active roller 3 drives the first transmission belt 36, the first lower driven roller 32, the second transmission belt 37, the upper driven roller 4 and the second lower driven roller 33 to operate, and the glass fiber filaments 41 fall under the dragging action of the first transmission belt 36 and the second transmission belt 37. A transmission belt 36 is sleeved outside the active roller 3 and the first lower driven roller 32, and a second transmission belt 37 is sleeved outside the upper driven roller 4 and the second lower driven roller 33. The main working surfaces of the first transmission belt 36 and the second transmission belt 37 are planes. In the process of dragging the glass fiber filaments 41, the first transmission belt 36 and the second transmission belt 37 can effectively prevent the glass fiber filaments 41 from rotating and entangled on the rollers. There is no need to stop the machine to clean the glass fiber filaments 41 wound on the rollers, which improves the uniformity of laying the glass fiber filaments 41, thereby improving the molding quality and efficiency of the glass fiber continuous mat. The first transmission belt 36 and the second transmission belt 37 are preferably made of antistatic materials, which can further improve the uniformity of laying the glass fibers. The glass fiber continuous mat laying device provided by the present invention has low requirements on the temperature and humidity of the working environment and can effectively save energy.

[0029] In a specific embodiment of the present invention, the glass fiber continuous mat laying device also includes a main frame 1, a support frame driving device, a wire outlet plate 6 and a conveying device 10. The main frame 1 is fixedly provided with a plurality of parallel transverse slide rail groups in the longitudinal direction, and each transverse slide rail group includes two parallel transverse slide rails 7, and each transverse slide rail 7 is arranged along the transverse direction of the main frame 1; each transverse slide rail group is slidably connected to a lower frame body 38, and the support frame driving device is connected to the lower frame body 38 to drive the lower frame body 38 to slide back and forth on the transverse slide rail group; a plurality of wire outlet holes 11 are opened on the wire outlet plate 6 along the longitudinal direction of the main frame 1, and the wire outlet plate 6 is located above the active roller 3 and the upper driven roller 4 and is driven by the wire outlet plate driving device to reciprocate along the longitudinal direction of the main frame 1; the conveying device 10 is arranged below the transverse slide rail 7 for conveying the glass fiber continuous mat along the longitudinal direction of the main frame 1. The glass fiber falls onto the conveying device 10 under the dragging action of the first transmission belt 36 and the second transmission belt 37. The conveying device 10 is arranged below the transverse slide rail 7, and the glass fiber is unidirectionally conveyed along the longitudinal direction of the main frame 1. Each transverse slide rail 7 is arranged along the transverse direction of the main frame 1, and the support frame 2 reciprocates along the transverse direction of the main frame 1. During the movement of the conveying device 10, the support frame 2 reciprocates perpendicular to the conveying direction of the conveying device 10, and during the movement of the support frame 2, the wire outlet plate 6 also reciprocates along the longitudinal direction of the main frame 1 at the same time, so that the glass fiber passing through the wire outlet hole 11 is in a short-distance vibration state along the longitudinal direction of the main frame 1, as shown in FIG. Figure 5 As shown, the glass fibers falling onto the conveying device 10 are arranged in a generally V-shaped track, and the V-shaped track has an annular structure 31. Multiple support frames 2 move simultaneously, so that the glass fibers arranged in the V-shaped track are closely arranged on the conveyor belt to form a glass fiber mesh. The glass fiber mesh can be obtained by subsequent bonding with resin or sewing to obtain a glass fiber mat. Since the glass fiber mesh is formed by continuous glass fibers arranged along the V-shaped track with the annular structure 31, the annular structure 31 makes the glass fiber reinforced plastic made of the continuous glass fiber mat have high strength in all directions, and the continuous glass fibers improve the overall strength of the glass fiber reinforced plastic. By using the glass fiber continuous mat laying device provided by the present invention, the overall strength of the glass fiber reinforced plastic made of glass fibers of the same weight is increased by 30%.

[0030] The first transmission belt 36 and the second transmission belt 37 are both rubber transmission belts, which can effectively prevent static electricity from being generated between the glass fiber filaments 41 and the first transmission belt 36 and the second transmission belt 37, avoid the glass fiber filaments 41 from getting stuck or entangled, and improve the uniformity of glass fiber laying. It should be noted that the first transmission belt 36 and the second transmission belt 37 of the glass fiber continuous mat laying device provided by the present invention are not limited to being made of rubber materials, as long as their main working surfaces are flat and can effectively prevent the glass fiber from rotating, they are preferably made of antistatic materials, which can further improve the molding quality and efficiency of the glass fiber continuous mat.

[0031] In another specific embodiment of the present invention, the glass fiber continuous mat laying device also includes a wire guide device. In order to reduce the friction between the glass fiber filaments 41 and the wire guide device and the generation of glass fiber waste, and effectively avoid the breakage of the glass fiber filaments 41, the wire guide device includes a wire guide frame 29 fixedly arranged on the main frame 1, and a support rod 42 is arranged on the top of the wire guide frame 29. The axial direction of the support rod 42 is parallel to the horizontal direction of the main frame 1. A plurality of guide vertical rods 43 are fixedly arranged on the support rod 42 in the axial direction, and the space between two adjacent guide vertical rods 43 is used to guide a plurality of glass fiber filaments 41. The support rod 42 and the guide vertical rod 43 are preferably stainless steel pipes.

[0032] In another specific embodiment of the present invention, a first vertical column 12 and a second vertical column 1313 are fixedly arranged on both ends of the longitudinal direction of the main frame 1 on each upper frame 39 of the glass fiber continuous mat laying device, and the first vertical column 12 is fixedly connected to one end of the wire outlet plate 6 through a first extension rod 44, and the two ends of the first extension rod 44 are respectively fixedly connected to the top of the first vertical column 12 and one end of the wire outlet plate 6, and the other end of the wire outlet plate 6 is fixedly connected to a through-rod 15, and a support plate 14 is fixedly arranged on the second vertical column 1313 through a second extension rod 45, and the two ends of the second extension rod 45 are respectively fixedly connected to the top of the second vertical column 1313 and one end of the support plate 14, and a support hole is opened at the other end of the support plate 14, and the through-rod 15 can freely pass through the support hole, and the wire outlet plate driving device is connected to the first vertical column 12. The wire outlet plate driving device drives the first vertical column 12 to reciprocate within a small longitudinal range of the main frame 1, thereby driving the wire outlet plate 6 to follow the first vertical column 12 to reciprocate along the longitudinal direction of the main frame 1. During the movement of the main frame 1, the support plate 14 supports the connecting rod 15 that freely passes through the support hole, thereby supporting the wire outlet plate 6.

[0033] A vibration track 16 is fixedly provided on the upper frame 39, and the vibration track 16 is located between the first vertical column 12 and the second vertical column 13. A second slider 17 is fixedly provided at the bottom end of the first vertical column 12, and the wire-out plate driving device is connected to the second slider 17 slidably connected to the vibration track 16. The wire-out plate driving device drives the second slider 17 to slide back and forth within a small range on the vibration track 16. During the lateral reciprocating sliding of the support frame 2 along the main frame 1, the wire-out plate 6 is in a short-distance vibration state along the longitudinal direction of the main frame 1. The glass fiber filaments 41 will swing back and forth along the longitudinal direction of the main frame 1 during the falling process, so that the glass fibers falling onto the conveying device 10 form many continuous annular structures. The annular glass fibers effectively enhance the strength of the formed glass fiber reinforced plastics in all directions and the overall strength.

[0034] In another specific embodiment of the present invention, in order to reduce the friction force on the glass fiber, a ceramic ring is fixedly installed in each wire outlet hole 11 of the glass fiber continuous mat laying device.

Since the diameter of the active roller is larger than the diameter of the first lower driven roller, and the diameter of the upper driven roller is larger than the diameter of the second lower driven roller, when the second transmission belt contacts the first transmission belt, the glass fiber filaments 41 between the second transmission belt and the first transmission belt fall vertically, and the side surfaces of the first transmission belt and the second transmission belt close to the glass fiber filaments 41 form an acute angle with the vertical plane, so that the glass fiber filaments 41 can fall vertically smoothly without sticking to the first transmission belt and the second transmission belt, thereby further effectively preventing the glass fiber filaments 41 from being entangled on the rollers, further improving the uniformity of glass fiber laying, and improving the molding quality and efficiency of glass fiber continuous mat.
