Description

A pultrusion process for producing composite materials with fiber introduction devices on both sides Technical Field

[0001] This utility model belongs to the field of composite material pultrusion technology, specifically relating to a fiber introduction device on both sides of a composite material produced by pultrusion process. Background Technology

[0002] Pultrusion is a highly efficient method for producing composite materials, widely used in aerospace, automotive, construction, petrochemical and other fields. Its core principle is to pull out continuous fibers (such as glass fibers or carbon fibers) impregnated with resin through traction equipment and heat and cure them in a mold to finally form composite material products with a constant cross-sectional shape.

[0003] When producing composite materials using the pultrusion process, stress is concentrated on the sides or corners of the product. At the same time, carbon fiber has high strength, and as the production time increases, the mold in these areas may be damaged first.

[0004] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a fiber introduction device for producing composite materials in a pultrusion process.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to provide a fiber introduction device on both sides of composite materials produced by pultrusion process, which can solve the problem of mold damage caused by stress concentration on both sides or corners during production and the high strength of carbon fibers.

[0007] To achieve the above objectives, a specific embodiment of this utility model provides a fiber introduction device for producing composite materials using a pultrusion process, comprising: a fixed base and an introduction device;

[0008] A support arm is fixed on the fixed base. A groove is carved on the support arm. A slider is slidably arranged in the groove. A pair of first racks are fixed on the two side walls at the lower end of the groove. A first gear and a second gear that mesh with each other are installed in the slider. The first gear and the second gear mesh with the pair of first racks respectively. A first rotating shaft is fixed on the first gear. A rotating handle is installed at one end of the first rotating shaft outside the slider. A locking mechanism is installed in the slider.

[0009] The inlet device is mounted on the slider. The inlet device includes a fixed shaft, which is fixed to the upper end of the slider. A rotating rod is rotatably mounted on the fixed shaft. A screw is fixed on the fixed shaft. A clamping ring is threaded onto the screw. The clamping ring presses against the rotating rod. An insert rod is slidably mounted on the end of the rotating rod. A wire ring is fixed to one end of the insert rod outside the rotating rod.

[0010] In one or more embodiments of this utility model, the fixing base is provided with multiple bolt holes, and bolts are inserted into the bolt holes to fix the fixing base in the installation position.

[0011] In one or more embodiments of this utility model, a pair of support feet are fixed between the bottom of the support arm and the fixed base, and the pair of support feet provide support for the support arm.

[0012] In one or more embodiments of this utility model, the locking mechanism includes a pair of locking heads that mesh with the first rack. A second rack is fixed to one side of each pair of locking heads that is close to each other. The locking head is locked onto the first rack on both sides by the pair of second racks.

[0013] In one or more embodiments of this utility model, a second rotating shaft is inserted into the slider. One end of the second rotating shaft, located inside the slider, is fixed with a third gear that meshes with a pair of second racks. The third gear is driven to rotate by the second rotating shaft, and the third gear drives the pair of second racks to move in opposite directions, so that the pair of second racks simultaneously drive the chuck to engage with the first rack, or to move away from the first rack.

[0014] In one or more embodiments of this utility model, a rotating head is fixed at one end of the second rotating shaft outside the slider. A rotating component is rotatably mounted on the rotating head, and the rotating component drives the rotating head to rotate, which in turn drives the second rotating shaft to rotate.

[0015] In one or more embodiments of this utility model, a first locking body and a second locking body are fixed at the bottom of the slider, and the rotating component is locked on the first locking body or the second locking body. When the slider is fixed, a pair of locking heads are locked on the first rack. At this time, the rotating component can be locked on the first locking body to prevent the locking heads from being released from the first rack due to the rotation of the rotating component. When it is necessary to move the slider, a pair of locking heads are locked on the first rack. At this time, the rotating component can be locked on the second locking body to prevent the position of the locking heads from affecting the movement of the slider.

[0016] In one or more embodiments of this utility model, each of the pair of card heads is fixed with a slide rod, and each of the pair of second racks is drilled with a slot adapted to the slide rod. A spring is installed between the card head and the second rack on the slide rod. The pair of slide rods slide in the pair of slots, thereby limiting one end of the card head and the second rack, preventing the position of the card head and the second rack from shifting, which would cause the pair of card heads to not be able to be locked in the pair of first racks.

[0017] In one or more embodiments of this utility model, a plurality of semi-circular locking blocks are evenly fixed on the insertion rod, and an adjustment groove is chiseled on the rotating rod. A plurality of semi-circular slots that are adapted to the semi-circular locking blocks are evenly chiseled on the side wall of the adjustment groove. When it is necessary to rotate and adjust the position of the wire ring, the wire ring is first pulled outward so that the semi-circular locking block is pulled out of the semi-circular slot and moved into the adjustment groove. Then the position of the wire ring is rotated. After the rotation is completed, the wire ring is inserted into the rotating rod so that the semi-circular locking block is locked in the semi-circular slot.

[0018] In one or more embodiments of this utility model, a limiting card is provided in the adjustment groove on the insertion rod. By locking the limiting card in the adjustment groove and on the insertion rod, the wire ring is prevented from moving outward, thereby preventing the semi-circular card block from moving out of the semi-circular card groove, and thus preventing the wire ring from rotating during the operation of the equipment.

[0019] Compared with the prior art, this utility model changes the angle at which the fiber enters the mold through related structural design, and accurately positions the fiber introduction position, thereby reducing damage to the side or corner position of the pultrusion product mold.

Detailed Implementation

[0031] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0032] As shown in Figures 1 to 8, a fiber introduction device for producing composite materials by pultrusion process in one embodiment of the present invention includes a fixed base 1 and an introduction device 2.

[0033] As shown in Figures 2 and 7, a support arm 101 is fixed on the fixed base 1. A groove 104 is cut on the support arm 101. A slider 105 is slidably arranged in the groove 104. By sliding the slider 105 in the groove 104, the slider 105 drives the guide device 2 to move, thereby adjusting the position of the guide device 2.

[0034] In addition, a pair of first racks 106 are fixed on the lower side walls of the slide groove 104. A first gear 107 and a second gear 108 are installed inside the slider 105. The first gear 107 and the second gear 108 are respectively meshed with the pair of first racks 106. A first rotating shaft 109 is fixed on the first gear 107. A rotating handle 110 is installed on one end of the first rotating shaft 109 outside the slider 105. The rotating handle 110 drives the first gear 107 to rotate through the first rotating shaft 109. The rotation of the first gear 107 drives the second gear 108 to rotate in the opposite direction. When the first gear 107 and the second gear 108 rotate, the slider 105 slides on the slide groove 104 through the meshing first racks 106 on both sides.

[0035] Secondly, a locking mechanism 111 is installed inside the slider 105. The locking mechanism 111 is used to fix the slider 105 when it is not moving, so that it cannot move.

[0036] As shown in Figures 1 and 2, the mounting base 1 has multiple bolt holes 102. Bolts are inserted into the bolt holes 102 to fix the mounting base 1 in the installation position. A pair of support legs 103 are fixed between the bottom of the support arm 101 and the mounting base 1, and the pair of support legs 103 provide support for the support arm 101.

[0037] As shown in Figures 5 to 8, the locking mechanism 111 includes a pair of locking heads 112 that mesh with the first rack 106. A second rack 113 is fixed on one side of each pair of locking heads 112 that are close to each other. The pair of locking heads 112 are pushed by the pair of second racks 113 to lock onto the first racks 106 on both sides, thereby locking the slider 105.

[0038] As shown in Figures 5 to 8, a second rotating shaft 115 is inserted into the slider 105. One end of the second rotating shaft 115, located inside the slider 105, is fixed with a third gear 114 that meshes with a pair of second racks 113. The second rotating shaft 115 drives the third gear 114 to rotate, and the third gear 114 drives the pair of second racks 113 to move in opposite directions, so that the pair of second racks 113 simultaneously drive the locking head 112 to lock onto the first rack 106, or to move away from the first rack 106.

[0039] As shown in Figures 5 to 8, a rotating head 116 is fixed at one end of the second rotating shaft 115 outside the slider 105. A rotating component 117 is rotatably mounted on the rotating head 116. The rotating component 117 drives the rotating head 116 to rotate, and the rotating head 116 drives the second rotating shaft 115 to rotate.

[0040] As shown in Figures 5 to 8, the bottom of the slider 105 is fixed with a first locking body 118 and a second locking body 119. The rotating part 117 is locked on the first locking body 118 or the second locking body 119. When the slider 105 is fixed, a pair of locking heads 112 are locked on the first rack 106. At this time, the rotating part 117 can be locked on the first locking body 118 to prevent the locking heads 112 from being released from the first rack 106 due to the rotation of the rotating part 117. When it is necessary to move the slider 105, the pair of locking heads 112 are not locked on the first rack 106. At this time, the rotating part 117 can be locked on the second locking body 119 to prevent the position of the locking heads 112 from affecting the movement of the slider 105.

[0041] As shown in Figures 5 to 8, each pair of locking heads 112 is fixed with a slide rod 120, and each pair of second racks 113 is drilled with a slot 121 that matches the slide rod 120. A spring 122 is installed between the locking head 112 and the second rack 113 on the slide rod 120. The pair of slide rods 120 slide in the pair of slots 121, thereby limiting one end of the locking head 112 and the second rack 113, preventing the position of the locking head 112 and the second rack 113 from shifting, which would cause the pair of locking heads 112 to not be locked in the pair of first racks 106.

[0042] As shown in Figures 1 to 3, the infeeding device 2 is installed on the slider 105. The infeeding device 2 includes a fixed shaft 201, which is fixed to the upper end of the slider 105. A rotating rod 202 is rotatably mounted on the fixed shaft 201. By rotating the rotating rod 202, the rotating rod 202 drives the guide ring 205 to rotate, thereby adjusting the angle of the fiber infeeding mold.

[0043] In addition, a screw 203 is fixed on the fixed shaft 201, and a clamping ring 204 is threaded onto the screw 203. The clamping ring 204 presses on the rotating rod 202. By rotating the clamping ring 204 on the screw 203, the clamping ring 204 is pressed against the rotating rod 202, thereby fixing the rotating rod 202.

[0044] Secondly, an insert rod 206 is slidably provided on the end of the rotating rod 202. A guide ring 205 is fixed at one end of the insert rod 206 outside the rotating rod 202. The insert rod 206 drives the guide ring 205 to rotate, and the rotation angle of the guide ring 205 is adjusted so that the guide ring 205 adapts to the angle of the fiber.

[0045] As shown in Figures 1 to 3, multiple semi-circular locking blocks 208 are evenly fixed on the insertion rod 206, and an adjustment groove 207 is carved on the rotating rod 202. Multiple semi-circular slots 209 that are adapted to the semi-circular locking blocks 208 are evenly carved on the side wall of the adjustment groove 207. When it is necessary to rotate and adjust the position of the guide ring 205, the guide ring 205 is first pulled outward, so that the semi-circular locking blocks 208 are pulled out from the semi-circular slots 209 and moved into the adjustment groove 207. Then, the position of the guide ring 205 is rotated. After the rotation is completed, the guide ring 205 is inserted into the rotating rod 202, so that the semi-circular locking blocks 208 are locked in the semi-circular slots 209.

[0046] As shown in Figures 1 to 3, a limiting clip 210 is provided in the adjustment groove 207 on the insertion rod 206. By locking the limiting clip 210 in the adjustment groove 207 and on the insertion rod 206, the wire ring 205 is prevented from moving outward, thereby preventing the semi-circular clip 208 from being removed from the semi-circular clip 209, and thus preventing the wire ring 205 from rotating during equipment operation.

[0047] Working principle: This device needs to be used in pairs. It is installed on both sides of the fiber inlet mold. In specific use, the slider 105 is slid on the slide groove 104 to drive the inlet device 2 to adjust its horizontal position. During the adjustment process, the rotating part 117 rotates around the second rotating shaft 115 as the axis, rotating the rotating part 117 out of the first clamping body 118. Then, the rotating part 117 is rotated downward around the rotating head 116 as the axis. Then, the rotating part 117 rotates again around the second rotating shaft 115 as the axis. After rotating to the position of the second clamping body 119, the rotating part 117 is clamped on the second clamping body 119. When the rotating part 117 rotates around the second rotating shaft 115 as the axis, it drives the second rotating shaft 115 to rotate. The second rotating shaft 115 drives the third gear 114 to rotate. The third gear 114 drives a pair of clamping heads 112 to move away from the first rack 106 through a pair of second racks 113, so that the slider 105 can slide on the slide groove 104.

[0048] When adjusting the position of slider 105 on slide groove 104, rotate handle 110. Rotate handle 110 drives first gear 107 to rotate through first shaft 109. Rotation of first gear 107 drives second gear 108 to rotate in the opposite direction. When first gear 107 and second gear 108 rotate, slider 105 slides on slide groove 104 through first rack 106 meshing on both sides. After adjusting the position of slider 105, remove rotating part 117 from second locking body 119, rotate rotating part 117 to lock rotating part 117 in first locking body 118, so that a pair of locking heads 112 are locked on first rack 106, locking slider 105.

[0049] Then, rotate the clamping ring 204 to loosen the rotating rod 202. Then, rotate the rotating rod 202 to adjust its position. After adjustment, rotate the clamping ring 204 again to fix the rotating rod 202. Then, pull the limiting clip 210 out of the adjusting groove 207. Then, pull the wire ring 205 outward. The wire ring 205 drives the insertion rod 206 to move. The insertion rod 206 pulls the semi-circular clip 208 out of the semi-circular slot 209 and moves it into the adjusting groove 207. Then, rotate the position of the wire ring 205. After rotation, insert the wire ring 205 into the rotating rod 202 so that the semi-circular clip 208 is locked in the semi-circular slot 209. Then, insert the limiting clip 210 into the adjusting groove 207. Then, the fibers on both sides are inserted through the wire ring 205.
