Description

Technical Field

[0001] The present invention relates to the technical field of composite material processing, in particular to a thermoplastic prepreg tape processing device based on a winding process. Background Art

[0002] Thermoplastic prepreg winding technology uses continuous fiber tapes or tows pre-impregnated with thermoplastic resin to create annular or near-annular composite structures such as pipes, tanks, and shells. During the winding process, a heating device heats the prepreg tape to its melting point, causing the resin to flow and bond the fibers, forming a composite layer. After winding, the resin is cooled to rapidly solidify and retain its shape.

[0003] The current winding molding device mainly adds a laser structure to the winding wire nozzle, and then irradiates the laser near the bonding point between the prepreg tape and the substrate to complete the heating of the prepreg tape and the substrate. It only satisfies the provision of heat source and the application of pressure when the prepreg tape contacts the prepreg tape on the raised core mold surface to promote the bonding between the prepreg tapes. It ignores the complexity of the core mold surface during the molding process. The common pressure roller cannot adapt to the core mold surface with large local changes, which directly affects the bonding strength between the composite material layers.

[0004] At the same time, since the thermoplastic prepreg tape is a pre-prepared solid tape, its tape width is fixed, and it is not easy for the tapes to be entangled and bonded to each other. In addition, the thermoplastic prepreg is sensitive to temperature. Too high or too low a temperature will affect the fluidity of the material, the wettability of the fiber and resin, and the quality of the final product. However, the existing winding molding device cannot adjust the molding temperature in real time. It does not take into account the different response times of different heat sources irradiated on the core mold and the need to preheat the prepreg tape in advance in special scenarios, which directly affects the bonding strength between the composite material layers, thereby affecting the process control of the thermoplastic prepreg tape winding molding and the quality of the final molded component.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] The purpose of the present invention is to provide a thermoplastic prepreg tape processing device based on a winding process, which overcomes the problem of fixed width size of the thermoplastic prepreg tape, improves the interlayer bonding effect of the thermoplastic prepreg tape, and improves the quality of the final molded component.

[0037] 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.

[0038] like Figures 1-9As shown, this embodiment provides a thermoplastic prepreg tape processing device 100 based on a winding process. The device comprises a housing 5, a slitting mechanism 1, a preheating and gluing mechanism 2, a flexible pressure roller 4, a controller, and two mounting mechanisms 3. The slitting mechanism 1, the preheating and gluing mechanism 2, and the flexible pressure roller 4 are sequentially arranged in the housing 5 along the transport direction of the thermoplastic prepreg tape. The two mounting mechanisms 3 are both arranged on the housing 5, located above and below the preheating and gluing mechanism 2. A temperature monitoring component is mounted below the upper mounting mechanism 3, while a heating component is mounted above the lower mounting mechanism 3. Both the temperature monitoring component and the heating component are connected to the controller. The temperature monitoring component monitors the temperature of the area below it, and the controller regulates the heating temperature of the heating component based on the temperature detected by the temperature monitoring component. In this embodiment, the temperature monitoring component is a thermal infrared camera with a display screen that can capture the temperature of the object surface. The heating component is a laser heating device, and the controller adjusts the heating temperature of the laser heating device by adjusting the laser power.

[0039] The slitting mechanism 1 includes an adjustable slitting tool 108 for slitting the thermoplastic prepreg tape, thereby adjusting the width of the thermoplastic prepreg tape. The preheating and gluing mechanism 2 is used to preheat and gluing the thermoplastic prepreg tape that continues to be transported after slitting, thereby increasing the adhesiveness of the thermoplastic prepreg tape. The subsequent component of the flexible pressure roller 4 is the core mold. The flexible pressure roller 4 is used to apply pressure to the heated and gluing thermoplastic prepreg tape. After being deformed by pressure, the flexible pressure roller 4 is used to fit the core mold surface to provide pressure for the thermoplastic prepreg tape to adhere.

[0040] During operation, the slitting tool 108 slits the thermoplastic prepreg tape, which can provide adjustment of the width of the thermoplastic prepreg tape to overcome the problem of fixed width of the thermoplastic prepreg tape; the preheating and gluing mechanism 2 preheats and glues the thermoplastic prepreg tape that continues to be conveyed after slitting, which is convenient for subsequent bonding between layers of the thermoplastic prepreg tape, and by synchronously monitoring and regulating the heating temperature, it can reduce the influence of external environmental regulation on the bonding strength between the thermoplastic prepreg tapes. The flexible pressure roller 4 applies pressure to the heated and glue-glued thermoplastic prepreg tape to adapt to the complex core model surface, and improves the bonding strength between the thermoplastic prepreg tapes through adaptive fitting and pressurization, thereby improving the quality of the final molded component.

[0041] like Figure 3 As shown, the slitting mechanism 1 in this embodiment also includes a fixed plate 101 and a support assembly. The fixed plate 101 is fixed in the housing 5. The support assembly is arranged on the upper part of the fixed plate 101. The position of the support assembly on the fixed plate 101 is adjustable. The slitting tool 108 is arranged on the support assembly. The slitting tool 108 and the fixed plate 101 are used to transmit the thermoplastic prepreg tape.

[0042] Specifically, the support assembly includes a support plate 106, two stops 107, and two limit plates 104. The two limit plates 104 are slidably mounted on the upper portion of the fixed plate 101, and the sliding direction is perpendicular to the transmission direction of the thermoplastic prepreg tape. The upper portion of the fixed plate 101 is provided with two strip grooves 102 for sliding at both ends of the limit plates 104. Each limit plate 104 is provided with a first strip hole 105 extending along the transmission direction of the thermoplastic prepreg tape. The two ends of the support plate 106 are respectively slidably mounted in the first strip holes 105 of the two limit plates 104, and a stop 107 is installed at both ends of the support plate 106. When the distance between the limit plates 104 and the slitting tool 108 needs to be adjusted, the limit plates 104 are moved relative to the support plates 106 in a direction perpendicular to the transmission direction of the thermoplastic prepreg tape. The slitting tool 108 is provided at the lower part of the supporting plate 106 . Scale bars 103 are provided on both sides of the fixing plate 101 . The extending direction of the scale bars 103 is consistent with the sliding direction of the limiting plate 104 .

[0043] The limiting plates 104 can slide relative to the fixed plate 101 in a direction perpendicular to the direction of transport of the thermoplastic prepreg tape, thereby adjusting the width of each limiting plate 104 from the slitting tool 108. The distance between the limiting plates 104 and the slitting tool 108 is indicated by the scale bar 103. The distance between one limiting plate 104 and the slitting tool 108 is adjusted according to the desired width of the thermoplastic prepreg tape, and the distance between the two limiting plates 104 is adjusted according to the overall width of the thermoplastic prepreg tape. When the thermoplastic prepreg tape passes through the slitting tool 108, it is cut into two parts by the slitting tool 108.

[0044] The slitting mechanism 1 also includes a winding roller 109, a winding disk 1010, an intermediate roller 1011 and a drive assembly. Both ends of the winding roller 109 and the intermediate roller 1011 are rotatably installed in the housing 5. The winding roller 109 is located between the slitting mechanism 1 and the intermediate roller 1011. The winding disk 1010 is rotatably installed on one side of the housing 5 and is located at the lower part between the winding roller 109 and the intermediate roller 1011. The drive assembly is used to drive the winding roller 109 and the winding disk 1010 to rotate in the same direction. The winding roller 109 is used to convey the slit thermoplastic prepreg tape, and the winding disk 1010 is used to wind the remaining thermoplastic prepreg tape waste after slitting.

[0045] The drive assembly includes a motor 1012, a first gear 1013, a second gear 1014, and a third gear 1015. The motor 1012 is arranged outside the housing 5. The power output shaft of the motor 1012 is connected to the central axis of the winding disk 1010. The first gear 1013 is fixedly mounted on the central axis of the winding disk 1010. The second gear 1014 is rotatably mounted in the housing 5 and meshes with the first gear 1013. The third gear 1015 is fixedly mounted on the central axis of the winding roller 109 and meshes with the second gear 1014. When the motor 1012 is working, the winding disk 1010 rotates, and the winding roller 109 is driven to rotate by the first gear 1013, the second gear 1014, and the third gear 1015. The structure of the first gear 1013, the second gear 1014, and the third gear 1015 makes the driving winding roller 109 and the winding disk 1010 rotate in the same direction.

[0046] like Figure 4 As shown, the preheating and glue-filling mechanism 2 includes a preheating component and a glue-filling component. The preheating component includes two heating rollers 201 rotatably installed in the housing 5. One heating roller 201 is located directly above the other heating roller 201. The space between the two heating rollers 201 is used for the thermoplastic prepreg tape that continues to be transported after slitting to pass through and preheat it. The two heating rollers 201 uniformly heat the upper and lower sides of the thermoplastic prepreg tape that continues to be transported after slitting, thereby melting the surface of the thermoplastic prepreg tape.

[0047] The glue filling assembly is located between the preheating assembly and the flexible pressure roller 4. The glue filling assembly includes two glue filling rollers 203 rotatably installed in the housing 5. One glue filling roller 203 is located directly above the other glue filling roller 203. The holding tank 205 for holding the thermoplastic resin is fixed in the housing 5 and is located below the lower glue filling roller 203. The lower glue filling roller 203 can contact the thermoplastic resin in the holding tank 205. The two glue filling rollers 203 are used for the thermoplastic prepreg tape that continues to be transported after heating to pass through and glue it, that is, the glue filling rollers 203 are used to apply thermoplastic resin to the surface of the thermoplastic prepreg tape that continues to be transported after heating, so that the thermoplastic prepreg tapes are bonded to each other.

[0048] In this embodiment, by coating the surface of the thermoplastic prepreg tape with a thermoplastic resin, the coating is relatively thin, and thus the bonding performance thereof can be greatly improved without affecting the winding shape thereof.

[0049] In order to improve the preheating effect and the glue repair effect, the preheating assembly and the glue repair assembly are both provided in plurality, and the plurality of preheating assemblies and the plurality of glue repair assemblies are arranged in sequence along the transmission direction of the thermoplastic prepreg tape.

[0050] In this specific embodiment, two preheating components and two glue filling components are provided.

[0051] Specifically, a plurality of heating rods 202 are evenly arranged inside the heating roller 201 along the circumference of the central axis of the heating roller 201. Figure 5 As shown, a plurality of adhesive grooves 204 are uniformly arranged along the circumference of the outer wall of the adhesive filling roller 203. The length direction of the adhesive grooves 204 is consistent with the axial direction of the adhesive filling roller 203. When the adhesive filling roller 203, which is located at the bottom, rotates, its surface contacts the thermoplastic resin in the holding groove 205, causing the interior of the adhesive grooves 204 to be filled with thermoplastic resin. As a result, the surface of the thermoplastic prepreg strips that come into contact with the adhesive grooves 204 filled with thermoplastic resin is also filled with thermoplastic resin, so that the thermoplastic prepreg strips are bonded to each other.

[0052] like Figure 6 As shown, the mounting mechanism 3 includes a mounting platform. A temperature monitoring component is mounted on the lower portion of the upper mounting platform, and a heating component is mounted on the upper portion of the lower mounting platform. The mounting platform includes two slidingly connected covers 301. Each cover 301 is slidably mounted on the housing 5 via two sliding assemblies on either side. The sliding direction of each cover 301 aligns with the transport direction of the thermoplastic prepreg tape. Two limit pins 309 are located on either side of the two covers 301 to secure their relative positions. The sliding connection of the two covers 301 allows for adjustable length of the mounting platform, accommodating thermal infrared cameras and laser heating devices of varying sizes. The platform is then secured with limit pins 309.

[0053] like Figure 8 As shown, the sliding assembly includes a slider 302, a telescopic member 305, two locking members and a plurality of connecting bolts. The slider 302 is slidably installed on the housing 5. A receiving groove is provided at the end of the slider 302 away from the housing 5. One end of the telescopic member 305 is slidably installed in the receiving groove. Second strip holes 303 connected to the receiving groove are provided on both sides of the slider 302. Each locking member can pass through a second strip hole 303 and be installed on the telescopic member 305, thereby locking and fixing the telescopic member 305 on the slider 302; a plurality of first threaded holes 306 are provided at the end of the telescopic member 305 away from the slider 302, and a plurality of through holes 307 are provided on the cover body 301. Each connecting bolt is used to pass through a through hole 307 and be installed in a first threaded hole 306.

[0054] The locking member in this embodiment is a locking bolt 304, and a second threaded hole is provided on both sides of the telescopic member 305. Each locking bolt 304 passes through a second strip hole 303 and is installed in a second threaded hole, and the head of the locking bolt 304 is pressed against one side of the slider 302, thereby enabling the telescopic member 305 and the slider 302 to be locked and fixed.

[0055] like Figure 7As shown, the cover 301 in this embodiment is a U-shaped structure, including a main board and two side panels respectively arranged at both ends of the same side of the main board. The side panels are provided with third strip holes 308. The main board of one cover 301 is located on the side of the main board of the other cover 301 away from the housing 5, and the two side panels of one cover 301 are respectively located on the inner side of the two side panels of the other cover 301. The limiting pin 309 can be inserted into and clamped into the two third strip holes 308 on the same side of the two covers 301 to fix the relative position of the two covers 301. The end of the telescopic member 305 away from the slider 302 is provided with an L-shaped groove. The bottom and side surfaces of the L-shaped groove are both provided with multiple first threaded holes 306. The main board and side panels of the cover 301 are both provided with multiple through holes 307.

[0056] When the height of the sliding assembly needs to be adjusted, the locking bolt 304 is turned outward so that its head no longer abuts against the slider 302, allowing the telescopic member 305 to move relative to the slider 302. After the position of the telescopic member 305 is adjusted, the locking bolt 304 is turned inward so that its head abuts against the slider 302. In this embodiment, the height of the sliding assembly corresponding to one cover 301 is different from the height of the sliding assembly corresponding to the other cover 301, thereby allowing the mounting platform to be tilted.

[0057] When the tilt angle of the mounting platform needs to be adjusted, the cover 301 is separated from the sliding assembly. One method is to adjust the height of the sliding assembly to adjust the tilt angle of the mounting platform, and then install the cover 301 on the sliding assembly. Another method is to keep the height of the sliding assembly unchanged, allowing the two cover plates to slide relative to each other to adjust the length, and then install the cover 301 on the sliding assembly.

[0058] The setting angle and height of the temperature monitoring component can be adjusted by adjusting the inclination angle of the upper mounting platform, and the setting angle and height of the heating component can be adjusted by adjusting the inclination angle of the lower mounting platform.

[0059] like Figure 9 As shown, the flexible pressure roller 4 includes a flexible cylinder 401, an elastic support component, two end covers 402 and two rotating shafts 403. The elastic support component is arranged in the flexible cylinder 401. The elastic support component enables the flexible cylinder 401 to maintain a cylindrical shape when not under pressure. The two end covers 402 are respectively installed at both ends of the flexible cylinder 401. A rotating shaft 403 is provided on the outside of each end cover 402. The two rotating shafts 403 are both rotatably installed in the housing 5.

[0060] The elastic support assembly includes a spring 404 and multiple elastic discs 405. The multiple elastic discs 405 are arranged on the outside of the spring 404 at intervals. The outer diameter of each elastic disc 405 is equal to the inner diameter of the flexible cylinder 401, so that the elastic disc 405 supports the inner wall of the flexible cylinder 401 and maintains the cylindrical shape of the flexible cylinder 401. When the elastic disc 405 is under pressure, it deforms and loses support for the flexible cylinder 401.

[0061] The specific usage process is as follows: the slit thermoplastic prepreg tape is divided into two parts. The part with a limited width is transported to the next link by the winding roller 109 and the intermediate roller 1011. The remaining scraps are rolled up and collected by the rotating winding disk 1010. The winding disk 1010 and the winding roller 109 rotate simultaneously, applying the same tension to the two parts after slitting, which facilitates the slitting of the thermoplastic prepreg tape by the slitting cutter 108. After slitting, the thermoplastic prepreg tape is preheated between the heating rollers 201 and then glued between the glue filling rollers 203. At the same time, it is heated by a laser heating device and the temperature is monitored by a thermal infrared camera. The temperature is coordinated with the controller to reach the set temperature. Finally, the heated and glued thermoplastic prepreg tape is pressed by the flexible pressure roller 4, which can adapt to the core model surface with large local variations.

[0062] This specification uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
