Description

Technical Field

[0001] The utility model belongs to the technical field of pultrusion molding, and in particular relates to a composite material frame pultrusion layout device. Background Art

[0002] Fiber reinforced composites are composite materials formed by winding, molding or pultrusion of reinforcing fiber materials, such as glass fiber, carbon fiber, aramid fiber, basalt fiber, etc., with matrix materials. According to the different reinforcing materials, common fiber reinforced composites are divided into glass fiber reinforced composites (GFRP), carbon fiber reinforced composites (CFRP), aramid fiber reinforced composites (AFRP) and basalt fiber reinforced composites (CBF).

[0003] Glass fiber is a filament drawn from molten glass quickly. It can be divided into alkali, alkali-free, medium alkali and special glass fibers, such as high silica and quartz fibers, according to the raw material components. Commonly used glass fiber composite materials generally refer to resin (such as epoxy resin, phenolic resin, unsaturated polyethylene resin, etc.) based composite materials, which can be formed by hand lay-up, winding, pressing and other molding processes, or injection and pultrusion molding processes. Glass fiber reinforced composite materials can be widely used in manual machinery, chemical industry, transportation and other fields due to their light weight, corrosion resistance, insulation and other characteristics.

[0004] The pultrusion process is to form and solidify continuous glass fiber bundles, tapes or cloths impregnated with resin glue through an extrusion die to continuously produce continuous fiber composite materials of unlimited length. This process is most suitable for producing FRP profiles of various cross-sectional shapes, such as rods, tubes, solid profiles (I-shaped, grooved, square profiles) and hollow profiles (door and window profiles, blades), etc.

[0005] In the pultrusion process, hot profiles are formed from the forming mold. Since the hot profile is soft, it is easy to cause film blockage and incomplete product curing. In addition, it is easy to bend downward under the action of gravity during pultrusion, affecting the product accuracy and performance of the composite material frame. Utility Model Content

[0037] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0038] like Figure 1 The figure shows a schematic diagram of the structure of the composite frame pultrusion layout device of the utility model, which includes a yarn guide component 1, a molding component 2 and a traction component 3. The yarn guide component 1 introduces the glass fiber bundle from the yarn frame into the glue injection box for impregnation, and then allows the impregnated glass fiber bundle to enter the molding component 2 for molding and curing, continuously producing a continuous fiber composite frame of unlimited length, and finally traction and transportation through the traction component 3.

[0039] Embodiment 1

[0040] There is one group (i.e. two) of yarn guide assemblies 1, which are distributed on both sides of the yarn guide plate 109, and are used to clamp the yarn guide plate 109 to prevent the yarn guide plate 109 from shaking when conveying the glass fiber bundle. Figure 5 , which is a front view of the yarn guide assembly 1, which is used to convey the glass fiber bundle to the molding assembly 2, and includes a slide rail 101, a slider 102, a slide plate 103, a vertical plate 104, a push cylinder 105, a clamping plate 106, a guide column 107, a guide sleeve 108 and a yarn guide plate 109. The slide rail 101 is fixed to the frame by screw fastening, and the slider 102 is slidably mounted on the slide rail 101.

[0041] The slide plate 103 is fixed on the slider 102, and a movable cylinder connected to the slide plate 103 is fixed on the top of the frame to push the slide plate 103 to move, thereby driving the slider 102 to move synchronously along the slide rail 101, thereby improving the stability of the movement of the slide plate 103 (the moving direction of the slide plate 103 is close to the molding component 2 or away from the molding component 2, and the movable cylinder is not shown in the figure).

[0042] There are two vertical plates 104, which are fixed at intervals on the top of the slide plate 103. The cylinder body of the pushing cylinder 105 is fixed on the opposite side of the vertical plate 104. The piston rod of the pushing cylinder 105 passes through the vertical plate 104 and is connected to the clamping plate 106. The pushing cylinder 105 drives the two clamping plates 106 to move inward or outward synchronously to clamp or release the yarn guide plate 109, so that different yarn guide plates 109 can be replaced according to the thickness of the glass fiber harness.

[0043] An array of yarn guide holes is provided on the yarn guide plate 109, and the glass fiber bundle passes through the yarn guide holes and extends into the molding component 2. Under the action of the traction force applied by the traction component 3, the glass fiber bundle is molded and cured by the molding component 2 to continuously produce a continuous fiber composite material frame of unlimited length.

[0044] Since the slide plate 103 can move toward the side close to the molding component 2 or away from the molding component 2, it will drive the yarn guide plate 109 to move synchronously. By changing the position of the yarn guide plate 109, the yarn feeding path can be effectively controlled to avoid abnormal tension during yarn feeding that causes the glass fiber bundle to bend or break, thereby avoiding affecting the subsequent molding of the composite material frame.

[0045] The forming assembly 2 is arranged on one side of the yarn guide assembly 1 and at the end of the conveying direction of the slide plate 103. Under the action of the traction force applied by the traction assembly 3, the continuous fiber composite material frame of unlimited length is continuously produced through the forming assembly 2 for forming and curing. The forming assembly 2 includes a first forming mold 201 and a second forming mold 202.

[0046] like Figure 2 As shown, the first molding die 201 is located inside the second molding die 202, and the first molding die 201 and the second molding die 202 are arranged side by side.

[0047] The traction component 3 is arranged on the side of the molding component 2 away from the yarn guide component 1, and is used to pull the composite material frame formed by the molding component 2 to avoid mold blocking or incomplete product curing. Figure 6 , 7As shown, the traction assembly 3 includes a traction frame 301, a support frame 302, a traction mechanism and a tensioning mechanism. There is a group of support frames 302 (i.e., two, an upper support frame and a lower support frame), the lower support frame is fixed to the top of the traction frame 301 through a profile, and the upper support frame is height-adjustably arranged above the lower support frame to traction composite frames of different heights.

[0048] The support column 303 is vertically fixed on the top of the traction frame 301, and the top plate 304 is fixed on the top of the support column 303 by screw fastening. The adjustment plate 306 is fixed on the top of the upper support frame, and the cylinder body of the adjustment cylinder 305 is fixed on the top plate 304. The piston rod of the adjustment cylinder 305 passes through the top plate 304 and is connected to the adjustment plate 306 of the upper support frame. The adjustment cylinder 305 drives the adjustment plate 306 to move up and down, and then drives the upper support frame to move up and down, so as to change the distance between the upper support frame and the lower support frame, thereby pulling composite material frames of different heights and improving versatility.

[0049] The guide column 307 is vertically fixed on the top of the traction frame 301 and is parallel to the support column 303. The guide sleeve 308 is sleeved on the guide column 307. The upper support frame is fixed to the guide sleeve 308. When the adjusting cylinder 305 drives the upper support frame to move up and down, it is guided by the guide sleeve 308 and the guide column 307 to avoid misalignment between the upper support frame and the lower support frame.

[0050] The traction mechanism is arranged on the inner side of the support frame 302, and the composite material frame formed by the molding assembly 2 is pulled by the traction mechanism arranged above and below to avoid mold blocking or incomplete product solidification. The traction mechanism includes a driving wheel 309, a driven wheel 310, a traction chain 311, a drive motor 312, a support plate 313, a lug 314, a connecting plate 315 and a traction part 316. The driving wheel 309 and the driven wheel 310 are rotatably mounted on both sides of the support frame 302, respectively, and the traction chain 311 is wound around the driving wheel 309 and the driven wheel 310 (the support frame 302 is used to limit the internal traction chain 311 to prevent the traction chain 311 from being disengaged).

[0051] The housing of the driving motor 312 is fixed on one side of the support frame 302. The driving shaft of the driving motor 312 passes through the support frame 302 and is connected to the driving wheel 309, which is used to drive the driving wheel 309 to rotate, and then drive the traction chain 311 to rotate, so as to clamp the composite material frame formed by the molding component 2 and complete the traction.

[0052] The support plate 313 is fixed on the inner side of the support frame 302 and is located inside the traction chain 311. On the one hand, the support plate 313 is used to prop up the support frame 302 to prevent the support frame 302 from deforming. On the other hand, when the traction chain 311 pulls the composite material frame, it is easy to deform downward under the action of gravity. The support plate 313 can support the traction chain 311 to avoid affecting the traction effect of the composite material frame.

[0053] like Figure 8 As shown, the lugs 314 are fixed on both sides of the traction chain 311. The connecting plate 315 is fixed on the top of the lug 314, and the traction part 316 is fixed on the side of the connecting plate 315 away from the traction chain 311. When the traction chain 311 rotates, the traction part 316 is driven to rotate synchronously, thereby pulling the composite material frame formed by the molding assembly 2 to avoid mold blocking or incomplete product curing. The traction part 316 is provided to increase the contact friction with the composite material frame, so as to avoid the traction chain 311 directly pulling the composite material frame and causing slippage.

[0054] The tensioning mechanism is disposed on one side of the support frame 302 close to the driven wheel 310, and is used to adjust the position of the driven wheel 310 to tension the traction chain 311, so as to prevent the traction chain 311 from being deformed and elongated due to long-term traction, thereby affecting the traction efficiency of the composite frame. Fig. 9 As shown, the tensioning mechanism includes a tensioning groove 317, a tensioning block 318, a slide groove 319, a locking block 320, a fixing column 321, an adjusting rod 322, an inner locking nut 323 and an outer locking nut 324. The tensioning groove 317 is horizontally opened on a side of the support frame 302 away from the driving wheel 309, and the tensioning block 318 is adjustably arranged in the tensioning groove 317.

[0055] The slide groove 319 is provided on the tension block 318, and the support frame 302 is clamped in the slide groove 319. When the tension block 318 moves, it relies on the guidance of the slide groove 319 to improve the accuracy of adjusting the position of the driven wheel 310. The driven shaft is rotatably installed between the tension blocks 318 through bearings, and the driven wheel 310 is sleeved on the driven shaft.

[0056] The locking block 320 is fixed on the tensioning block 318, the fixing column 321 is fixed on the outside of the support frame 302, and the adjusting rod 322 is fixed on the fixing column 321 and passes through the locking block 320 (the outer peripheral surface of the adjusting rod 322 is provided with an external thread, and a through hole is opened on the locking block 320, and the diameter of the through hole is larger than the outer diameter of the adjusting rod 322, so the locking block 320 can be freely adjusted along the length direction of the adjusting rod 322, thereby driving the tensioning block 318 to be freely adjusted in the tensioning groove 317).

[0057] The inner lock nut 323 and the outer lock nut 324 are respectively screwed on the adjustment rod 322, and the inner lock nut 323 and the outer lock nut 324 are respectively located on both sides of the locking block 320. After the position of the locking block 320 is adjusted, the inner lock nut 323 and the outer lock nut 324 are screwed to the two sides of the locking block 320 to lock the locking block 320.

[0058] Embodiment 2

[0059] The technical solutions in the second embodiment are basically the same as those in the first embodiment, and the only difference is that the layout of the first molding die 201 and the second molding die 202 is different. Figure 3 As shown, the first molding die 201 is arranged above the second molding die 202, and the projection of the first molding die 201 in the vertical direction coincides with the second molding die 202 (ie, the first molding die 201 and the second molding die 202 are distributed in a rectangular shape).

[0060] The upper and lower layers of the forming mold can save floor space to a great extent and improve area utilization.

[0061] Embodiment 3

[0062] The technical solution in the third embodiment is basically the same as the technical solution in the first embodiment, except that the layout of the first molding die 201 and the second molding die 202 is different. Figure 4 As shown, the first molding die 201 is arranged above the second molding die 202, and the projection of the first molding die 201 in the vertical direction falls on the inner side of the second molding die 202 (ie, the first molding die 201 and the second molding die 202 are distributed in an isosceles trapezoid).

[0063] The isosceles ladder distribution arrangement saves floor space and improves area utilization. At the same time, the molding waste of the upper first molding die 201 will not drip onto the lower second molding die 202, and will not affect the extrusion molding effect of the lower second molding die 202.

[0064] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
