Description

Technical Field

[0001] The present invention relates to the technical field of composite molding, and in particular to a suspended segmented combined continuous composite molding device and a molding method. Background Art

[0002] Carbon fiber reinforced composite plates are widely used in many industries such as aerospace, automobile manufacturing, and sports equipment due to their excellent properties such as high strength, low density, and corrosion resistance. However, the existing composite units are relatively large in overall volume, inconvenient for transportation, and the length of their heating and cooling units is fixed as a whole, resulting in poor use effects. After the equipment is lifted, the reference plane shifts, with one side of the equipment being higher and the other being lower, leading to poor product quality, belt deviation of the conveyor belt resulting in damage to the conveyor belt, and uneven pressure causing damage to the conveyor belt and the plate products, which makes the research and development of a new type of molding device an inevitable trend. The continuous preparation of carbon fiber reinforced composite plates mostly adopts the method of continuous hot pressing and cooling. By heating the carbon fiber prepreg tape and the substrate, and then using a pressure roller for rolling and bonding and cooling, the continuous molding of the carbon fiber composite plate is achieved. However, the movement of the existing carbon fiber composite plate generally relies on the driving of power rollers. Only relying on the driving of power rollers to move the composite plate easily causes the plate to move offset, affecting the uniformity of rolling, and thus affecting the quality of the composite plate.

[0003] The existing patent CN202420556275.2 discloses a thermoplastic composite press device with a modular structure, including a floor and a composite unit. The composite unit includes an intermediate press, a feeding end press, and a discharging end press. Hydraulic cylinders are provided at the upper ends of the frames of the intermediate press, the feeding end press, and the discharging end press. An upper mounting frame is provided at the lower end of the hydraulic cylinder, and a lower mounting frame is provided below the upper mounting frame. Horizontal adjustment components are provided on both sides of the upper mounting frame and the lower mounting frame close to each other. In this thermoplastic composite press device with a modular structure, the intermediate press is arranged between the feeding end press and the discharging end press, and several groups of feeding end presses and discharging end presses are provided. The feeding end presses and the discharging end presses can be set according to order requirements to effectively adjust the length of the heating zone and the cooling zone of the unit, avoiding waste of energy. In the above patent, the movement of the composite plate relies on the feeding end press or the composite press, and the stability of the movement of the composite plate is relatively poor, and the composite plate is prone to offset during the movement, affecting the composite effect of the composite plate.

[0023] Based on the forming method of the above-mentioned suspended segmented combined continuous composite forming device, it includes the following steps:

[0024] S1. The servo motor drives the lead screw to lift synchronously through the transmission rod and the lifter. The lead screw adjusts the heights of the first mounting seat, the second mounting seat, and the third mounting seat as required.

[0027] S4. The upper conduction block contacts the upper surface of the upper conveyor belt under the action of the spring, and the lower conduction block contacts the lower surface of the lower conveyor belt. The heating medium flows through the flow channels of the conduction blocks. The upper conduction block and the lower conduction block heat the sheet through the upper conveyor belt and the lower conveyor belt respectively.

[0028] S5. Extrude the sheet through the upper pressing roller and the lower pressing roller for compounding. After cooling through the cooling section, it is removed from the forming device.

[0029] The advantages and positive effects of the hanging type segmented combined continuous composite forming device and the forming method of the present invention are as follows:

The heating section, the pressing section, and the cooling section of the forming device of the present invention are all drawer-type structures, which can be assembled with any length as required, are convenient to install, meet the heating and cooling needs of different lengths, and have strong adaptability.

[0031] 2. An adjusting mechanism is provided at the feeding end. Through the adjusting mechanism, the tension of the conveyor belt can be adjusted and deviation rectification can be carried out, ensuring that the conveyor belt stably conveys the sheet, improving the conveying effect of the sheet, and thus improving the forming quality of the sheet.

[0032] 3. The first connecting seat of the heating component is slidably connected to the first support rail. This connection method is convenient for the installation of the first connecting seat. And when the transmission block expands due to heat, the distance between the transmission blocks can be increased to meet the expansion needs between the conduction blocks.

[0033] 4. The first mounting rod of the present invention is slidably connected to the first connecting seat. A spring for applying a downward elastic force is provided between the first connecting seat and the first connecting plate. Under the action of the spring, the transmission block is in contact with the surface of the conveyor belt, thereby improving the heating effect on the plate. And when the thickness of the plate is uneven, the first mounting rod can be lifted and lowered to ensure the smooth movement of the plate.

A limiting nut 211 for limiting the first mounting rod 27 is provided at the top end of the first mounting rod 27. A spring for applying a downward elastic force to the conduction block 29 is provided between the first connecting seat 24 and the first connecting plate 28. Under the action of the spring, the transmission block contacts the surface of the conveyor belt, thereby improving the heating effect on the plate; and when the thickness of the plate is uneven, the first mounting rod 27 can be lifted and lowered to ensure the smooth movement of the plate.

[0075] A flow channel 210 for the flowing medium is provided in the middle of the conduction block 29, and the medium heats the plate from the top of the plate through the conduction block 29. A pipeline for the flow of the medium can be provided in the flow channel 210, and adjacent transmission blocks are connected by a telescopic connecting plate, so as to realize the flow of the medium in the conduction block 29, and further heat the plate through the transmission block.

[0076] As Figure 11 shown. The structure of the lower heating component is basically the same as that of the upper heating component. The difference is that the second mounting rod 217 of the lower heating component is fixed on the second connecting seat 214. The lower heating component includes a second fixing seat 212, and the second fixing seat 212 is fixed on the second frame 21. Above the second fixing seat 212, a plurality of second connecting seats 214 arranged along the moving direction of the plate are provided. The second connecting seats 214 are connected to the second fixing seat 212 through the second support rails 213. Second limiting frames 215 are provided on both sides of the top of the second support rails 213, and second rollers 216 adapted to the second limiting frames 215 are provided on both sides of the second connecting seat 214. The second rollers 216 are located in the second limiting frames 215 and are slidably connected to the second limiting frames 215. Above the second connecting seat 214, a plurality of conduction blocks 29 are provided. The conduction blocks 29 are fixedly connected to the second mounting rod 217 through the second connecting plate 218. A through hole for the second mounting rod 217 to pass through is provided on the second connecting seat 214, and the second mounting rod 217 is fixed on the second connecting seat 214 through a locking nut. Since the bottom of the composite plate is the base plate and the upper part is the prepreg tape, the flatness of the base plate is relatively good. Directly fixing the second mounting rod 217 on the second connecting seat 214 is beneficial to improving the stability of the transmission block and the stability of the movement of the base plate.

[0077] As Figure 12As shown in the figure. The pressurizing section 3 includes a third rack 31 which is fixed on the ground. Inside the third mechanism, there are a third mounting seat 32 and a third fixing seat 34. The lower pressing roller 35 is rotatably arranged on the third fixing seat 34, and the third fixing seat 34 is fixed on the third rack 31. The upper pressing roller 33 is rotatably arranged on the third mounting seat 32, and motors for driving the upper pressing roller 33 and the lower pressing roller 35 to rotate are respectively arranged on the third mounting seat 32 and the third fixing seat 34.

[0078] On the third rack 31, there is a lifting mechanism 5 for driving the third mounting seat 32 to move up and down. The lifting mechanism 5 includes a servo motor 51. The servo motor 51 is connected with a lifter 53 through a transmission rod 52. The lead screw 54 of the lifter 53 is arranged at the four corners of the third mounting seat 32. The servo motor 51 is used to synchronously drive the lifter 53 to horizontally move the third mounting seat 32 up and down for adjustment, so as to avoid the left - right inclination of the third mounting seat 32, which may cause uneven surface pressure of the material.

[0079] The structure of the cooling section 4 is the same as that of the heating section 2, except that a refrigerant is introduced into the flow channel 210 of the transmission block, and the refrigerant cools the plate through the transmission block.

[0080] The forming method of the above - mentioned suspended segmented combined continuous composite forming device includes the following steps:

[0081] S1. The servo motor 51 drives the lead screw 54 to synchronously lift and lower through the transmission rod 52 and the lifter 53. The lead screw 54 adjusts the heights of the first mounting seat 12, the second mounting seat 22, and the third mounting seat 32 as required. The conveyor belt forms an endless conveyor belt through the power rollers in the power section and the guide rollers at the top or bottom of the device, via the deviation - correcting roller 15 and the tensioning roller 16 and back to the power rollers. The first cylinder 17 drives the sliding seat 18 to slide along the mounting plate 14, and the sliding seat 18 drives the tensioning roller 16 to move, and the tensioning roller 16 tensions the conveyor belt.

[0082] S2. Start the power rollers in the power section. The power rollers drive the conveyor belt to move, and feed the plate from the feeding section 1 between the upper conveyor belt and the lower conveyor belt, and the upper conveyor belt and the lower conveyor belt drive the plate to move.

[0083] S3. Detect the displacement of the conveyor belt through the displacement sensor 122. When the conveyor belt deviates, the displacement changes. The second cylinder 116 drives the aligning ball bearing seat 115 at the end of the deviation - correcting roller 15 to slide along the support seat 114, adjusts the angle of the deviation - correcting roller 15, and corrects the deviation of the conveyor belt.

[0084] S4. The upper conduction block 29 contacts the upper surface of the upper conveyor belt under the action of a spring, and the lower conduction block 29 contacts the lower surface of the lower conveyor belt. The heating medium flows through the flow channel 210 of the conduction block 29, and the upper conduction block 29 and the lower conduction block 29 heat the plate through the upper conveyor belt and the lower conveyor belt respectively.

[0085] S5. The plate is extruded by the upper pressing roller 33 and the lower pressing roller 35 for lamination. After cooling through the cooling section 4, it is removed from the forming device.

[0086] Therefore, by using the hanging segmented combined continuous composite forming device and forming method of the present invention, the problem that the existing composite plate has poor moving stability and affects the composite effect can be solved.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that they can still modify or equivalently replace the technical solutions of the present invention, and these modifications or equivalent replacements cannot make the modified technical solutions deviate from the spirit and scope of the technical solutions of the present invention.
