However, it is apparent to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features well known in the art are not described.

[0106] In order to fully understand the present invention, a detailed description will be provided in the following description. It should be understood that these embodiments are provided to make the disclosure of the present invention thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. Obviously, the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art. The preferred embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other embodiments.

[0107] Ordinal numbers such as "first" and "second" cited in the present invention are merely identifications and do not have any other meanings, such as a specific order, etc. Moreover, for example, the term "first component" itself does not imply the existence of the "second component", and the term "second component" itself does not imply the existence of the "first component".

[0108] It should be noted that the terms "upper", "lower", "front", "back", "left", "right", "inside", "outside" and similar expressions used in the present invention are for illustrative purposes only and are not limiting.

[0109] The invention discloses composite reinforcing rib production equipment and composite reinforcing rib.

[0110] The continuous fiber reinforced thermoplastic composite prepreg narrow strip used in the present invention is referred to as narrow strip for short; the manufactured continuous fiber reinforced thermoplastic composite reinforcing rib is referred to as composite reinforcing rib for short.

[0111] Continuous fiber reinforced thermoplastic composite tapes have high strength and high stiffness, which can meet the requirements of a variety of application scenarios, and they are lightweight (compared to traditional metal materials), making them particularly important in applications that require weight reduction. In addition, continuous fiber composite tapes are also corrosion-resistant and can be used for a long time in harsh environments, showing great application potential in many fields.

[0112] The thickness of the continuous fiber reinforced thermoplastic composite tape is usually about 0.15-0.4 mm, for example, it can be a continuous glass fiber reinforced polypropylene resin tape with a thickness of 0.26 mm.

[0113] Now, exemplary embodiments according to the present invention will be described in more detail with reference to the accompanying drawings.

[0114] like Figure 1 , Figure 2 , Figure 3 As shown, the composite reinforcing rib production equipment 100 comprises: an upper heating flow channel device 3 and a traction twisting device 6;

[0115] The heating channel device 3 is used to heat the narrow strip 110. The narrow strip 110 continuously runs through the heating channel device 3. The heating is completed during the passing process. The heated narrow strip 110 is in a molten state.

[0116] The traction twisting device 6 is arranged downstream of the heating flow channel device 3, and is used to roll and shape the heated narrow ribbon 110. The narrow ribbon 110 in a molten state is relatively soft and suitable for winding (twisting), and can also be shaped after winding;

[0117] like Figure 4 , Figure 5 , Figure 6As shown, the traction and twisting device 6 includes an outer tube 62, an inner tube 64 and a driving device 66. The inner tube 64 is arranged inside the outer tube 62 and is coaxial with the outer tube 62. The inner wall of the inner tube 64 is provided with a molding line 69. The driving device 66 drives the inner tube 64 to rotate, and the heated narrow band 110 enters the inner tube 64. The inner tube 64 causes the narrow band 110 to be wound and formed through the molding line 69.

[0118] Inside the inner tube 64 , the molding wire 69 and the heated narrow strip 110 can form a mosaic structure, and when the inner tube 64 rotates, the narrow strip 110 can be continuously pulled to run, thereby continuously processing the narrow strip 110 to manufacture the composite reinforcing rib 120 .

[0119] The composite reinforcing rib production equipment of this embodiment heats the continuous fiber reinforced thermoplastic composite prepreg narrow strip through a heating flow channel device, and then winds the heated narrow strip through a traction and twisting device. The continuous fiber reinforced thermoplastic composite prepreg narrow strip can be used to manufacture composite reinforcing ribs with special patterns and properties. The composite reinforcing ribs are environmentally friendly, pollution-free, and recyclable.

[0120] In one embodiment, if Figure 1 , Figure 2 As shown, the heating channel device 3 includes:

[0121] The third frame 31 is a frame structure and can be made by welding and assembling profiles;

[0122] A furnace body 32, which is disposed on the top of the third frame 31, and is cylindrical. A flow channel 33 extending along the axial direction is disposed inside the furnace body 32, and the narrow belt 110 can pass through the flow channel 33;

[0123] A plurality of heating devices 34 are disposed in the furnace body 32 and around the flow channel 33 , and are capable of heating the narrow strip 110 passing through the flow channel 33 . The heating devices 34 may be electric heating devices.

[0124] like Figure 7 As shown, the furnace body 32 can be divided into an upper furnace body 321 and a lower furnace body 322. The upper furnace body 321 and the lower furnace body 322 are hinged, and the upper furnace body 321 can be rotated and opened upward relative to the lower furnace body 322, so as to facilitate the setting of a traction rope and a narrow belt 110 in the flow channel 33, and also to facilitate repair and maintenance. High-temperature resistant materials need to be set in both the upper furnace body 321 and the lower furnace body 322, and the flow channel 33 can be distributed between the upper furnace body 321 and the lower furnace body 322.

[0125] In one embodiment, along the running direction of the narrow band 110, the heating temperature of the plurality of heating devices 34 increases in a gradient, and the highest temperature is determined according to the type of resin contained in the narrow band 110, and the resin can be heated to soften. By adopting a gradually increasing segmented heating method for the narrow band 110, the narrow band 110 can be heated to a suitable temperature while the narrow band 110 is running. Compared with adopting a single heating temperature, it can avoid heating the resin in the narrow band 110 to an overheated degree and save energy consumption of the heating device 34.

[0126] like Figure 1 , Figure 2 As shown, the heating channel device 3 includes:

[0127] There are at least five heating devices 34 , and along the running direction of the narrow band 110 , the heating temperature ranges of the at least five heating devices 34 are: 180-200° C., 200-220° C., 220-240° C., 240-260° C., 220-240° C.

[0128] The first four heating devices 34 heat up gradually, gradually heating the narrow strip 110 in the furnace body 32. The temperature of the last heating device 34 is lower than that of the fourth heating device 34, which keeps the narrow strip 110 warm, so that the narrow strip 110 has an appropriate temperature after being taken out of the furnace and is suitable for winding.

[0129] In one embodiment, if Figure 2 , Figure 7 As shown, the flow channel 33 includes an inlet end and an outlet end. The diameter of the inlet end is larger than the diameter of the outlet end. The flow channel 33 is approximately conical. This arrangement facilitates the operation of multiple narrow bands 110 in the flow channel 33. After the multiple narrow bands 110 pass through the cluster frame 4, the spacing between each other is still large, so the inlet end of the flow channel 33 also needs to be set to a larger diameter. Due to the restriction of the twisting auxiliary restriction frame 5, the spacing between the multiple narrow bands 110 is small, so the outlet end of the flow channel 33 can be set to a smaller diameter, and the outlet end with a smaller diameter is conducive to maintaining the temperature inside the flow channel 33.

[0130] In one embodiment, if Figure 4 , Figure 5 As shown, the forming line 69 is an outer spiral line or an inner spiral line. The outer spiral line protrudes from the inner wall of the inner tube 64, and the inner spiral line is recessed in the inner wall of the inner tube 64. The outer spiral line or the inner spiral line can form a chimeric structure with the narrow band 110, and the outer circumferential surface of the composite reinforcing rib 120 has a texture, similar to threaded steel.

[0131] In one embodiment, if Figure 1 , Figure 3 As shown, the traction twisting device 6 also includes:

[0132] The spray pipe 63, the outlet end of which is connected to the outer pipe 62, is used to transport cooling liquid into the inner pipe 62 to cool the inner pipe 64. When the inner pipe 64 is cooled, the composite reinforcement rib 120 in the molten state in the inner pipe 64 can be cooled and formed, and can maintain the structure and shape after being output from the inner pipe 64.

[0133] A plurality of spray pipes 63 may be connected to the outer tube 62 to increase the spraying amount of the coolant and achieve effective cooling of the inner tube 64 .

[0134] In one embodiment, if Figure 1 , Figure 3 As shown, the traction twisting device 6 also includes:

[0135] The sixth frame 61 is a frame structure and can be made by welding and assembling profiles;

[0136] The mounting seat 68 is arranged on the top of the sixth frame 61, the outer tube 62 and the inner tube 64 are arranged on the top of the mounting seat 68, the outer tube 62 is fixedly connected to the mounting seat 68, a water tank 681 is arranged on the top of the mounting seat 68, which is used to receive the coolant flowing out of the outer tube 62, and the inlet end of the spray pipe 63 is connected to the water tank 681. The two ends of the outer tube 62 are not closed, and the coolant can flow out from the two ends of the outer tube 62 after cooling the inner tube 64. A water pump can be arranged at the inlet of the spray pipe 63 to draw the coolant from the water tank 681 and transport it to the spray pipe 63.

[0137] In one embodiment, if Figure 5 , Figure 6 As shown, the traction twisting device 6 also includes:

[0138] The bearing 65 is disposed between the outer tube 62 and the inner tube 64 to support the inner tube 64 to rotate in the outer tube 62. A bearing 65 may be disposed at each end of the outer tube 62, or a plurality of bearings 65 may be disposed in the middle of the outer tube 62 to provide strong support for the inner tube 64 and maintain the stability of the inner tube 64.

[0139] In one embodiment, if Figure 1 , Figure 3 As shown, the traction twisting device 6 also includes:

[0140] The transmission device 67, the first end of the inner tube 64 extends out from the inside of the outer tube 62, the transmission device 67 connects the driving device 66 and the first end of the inner tube 64, and the driving device 66 drives the inner tube 64 to rotate through the transmission device 67. The driving device 66 may include a driving motor, a reducer, etc. The transmission device 67 may be a transmission belt or a transmission chain, and the first end of the inner tube 64 is correspondingly provided with a pulley or a sprocket connected to the transmission device 67, and the driving motor can drive the inner tube 64 to rotate when it is working.

[0141] In one embodiment, if Figure 1 , Figure 8 As shown, the composite reinforcement rib production equipment 100 also includes an unwinding frame 1, and the unwinding frame 1 includes:

[0142] The first frame 11 is a frame structure and can be made by welding and assembling profiles;

[0143] A plurality of unwinding shafts 12 are arranged in the first frame 11 , and a narrow tape roll including a narrow tape 110 is arranged on the unwinding shafts 12 . When the narrow tape 110 is running, the unwinding shafts 12 rotate along with it, and the unwinding shafts 12 rotate passively.

[0144] The first frame 11 is provided with a plurality of rotating shafts for mounting the unwinding shafts 12 , around which the unwinding shafts 12 can rotate. The plurality of unwinding shafts 12 are arranged in rows and layers in the first frame 11 to avoid interference between the output narrow bands 110 as much as possible.

[0145] In one embodiment, if Figure 8 , Fig. 9 As shown, the unwinding frame 1 also includes a tension control device, which is connected to the unwinding shaft 12. The tension control device slows down the rotation speed of the unwinding shaft 12 through friction force, avoids the narrow band 110 from being loosened during operation, keeps the narrow band 110 in a properly tensioned state in each device, ensures the quality of the composite reinforcement rib 120, and prevents accidents such as entanglement.

[0146] The tension control device may include a tensioning belt 15 and an elastic member 16. A roller may be provided at one end of the unwinding shaft 12. The first end of the tensioning belt 15 is fixed, and then the tensioning belt 15 contacts the circumferential surface of the roller. The second end of the tensioning belt 15 is connected to the elastic member 16. The elastic member 16 may be a spring. The friction force is generated by the pressure between the tensioning belt 15 and the roller, which can generate a certain rotational resistance to the unwinding shaft 12. When the narrow belt 110 is running, it always maintains a proper tension state with the unwinding shaft 12, which can avoid the narrow belt 110 from loosening. Keeping the narrow belt 110 in a proper tension state in each device ensures the quality of the composite reinforcement rib 120 and prevents accidents such as entanglement.

[0147] In one embodiment, if Figure 8 , Fig.10 As shown, the unwinding frame 1 also includes an expansion device, which is arranged in the unwinding shaft 12. The expansion device can expand the outer diameter of the unwinding shaft 12 to adapt to narrow tape rolls of different sizes.

[0148] The expansion device may include a plurality of elastic strips 17 and airbags 18, which are evenly arrayed in the unwinding shaft 12. The unwinding shaft 12 is provided with a plurality of receiving grooves along the axial direction, and the notches of the receiving grooves are connected to the outer circumferential surface of the unwinding shaft 12. A combination of an elastic strip 17 and an airbag 18 is provided in each receiving groove. The elastic strip 17 may be a rubber strip, and the cross section of the elastic strip 17 is an inverted T-shape. The top end of the elastic strip 17 may extend from the notch of the receiving groove, and the airbag 18 is inflated. The airbag 18 pushes the elastic strip 17 outwards. The outer diameter of the unwinding shaft 12 can be expanded by extending a plurality of elastic strips 17 outwards to adapt to a narrow tape roll with a larger inner diameter. When the airbag 18 is not inflated, it no longer pushes the elastic strip 17. The elastic strip 17 retracts into the receiving groove to reduce the outer diameter of the unwinding shaft 12 to adapt to a narrow tape roll with a smaller inner diameter.

[0149] In one embodiment, if Figure 1 , Figure 8 As shown, the unwinding frame 1 also includes:

[0150] Support roller 13, the support roller 13 is arranged on the top of the first frame 11, and supports the narrow belt 110 output from the unwinding shaft 12; corresponding to each row of unwinding shafts 12, a support roller 13 is arranged on the top of the first frame 11, and the support roller 13 can rotate with the narrow belt 110 when it runs. Although it supports the narrow belt 110, the friction between the support roller 13 and the narrow belt 110 is small;

[0151] The belt reed 14 is arranged on the top of the first frame 11. The belt reed 14 includes a plurality of limit rods for limiting the narrow belt 110 output from the support roller 13 in the horizontal direction to avoid mutual interference of the narrow belts 110. Each narrow belt 110 passes between two adjacent limit rods. Because of the obstruction of the limit rods, the plurality of narrow belts 110 remain in the same plane and will not interfere with each other.

[0152] In one embodiment, if Figure 1 , Fig.11 As shown, the composite reinforcing rib production equipment 100 further includes a guide frame 2, which is arranged between the unwinding frame 1 and the heating flow channel device 3, and the guide frame 2 includes:

[0153] The second frame 21 is a frame structure and can be made by welding and assembling profiles;

[0154] A mounting seat 22, the mounting seat 22 is disposed on the top of the second frame 21;

[0155] A plurality of guide rollers 23 are disposed in the mounting seat 22 and arranged up and down, and are used to guide the plurality of narrow belts 110 in layers up and down.

[0156] After being output from the unwinding rack 1, the multiple narrow strips 110 can be seen as being in the same horizontal plane without upper and lower layers. Compared with the heating flow channel device 3, the position is too high and cannot directly enter the heating flow channel device 3. After passing through the guide rack 2, the multiple narrow strips 110 are layered up and down, which meets the needs of winding the multiple narrow strips 110, and the height is lowered and the angle is adjusted at the same time, and then they can enter the heating flow channel device 3.

[0157] In one embodiment, if Figure 1 , Fig.12 As shown, the composite reinforcing rib production equipment 100 further includes a clustering rack 4, which is disposed at the inlet end of the flow channel 33 of the heating flow channel device 3 and is used to gather the multiple narrow strips 110 running in layers up and down.

[0158] After being output from the guide frame 2, the multiple narrow bands 110 have been layered up and down, but the spacing between the narrow bands 110 at the upper and lower positions is large, and the upper and lower positions do not correspond (it can be understood that the upper and lower positions do not completely overlap). By gathering them together through the clustering frame 4, the spacing between the narrow bands 110 at the upper and lower positions can be shortened, and the upper and lower positions of the multiple narrow bands 110 can also correspond, meeting the requirements for entering the heating flow channel device 3.

[0159] The cluster rack 4 may be disposed on the top of the third frame 31 of the heating channel device 3 , or a frame may be provided separately for the cluster rack 4 .

[0160] In one embodiment, if Fig.12 As shown, the cluster frame 4 includes:

[0161] An adjustment seat 41, wherein an adjustment channel is provided in the adjustment seat 41;

[0162] A plurality of guide rods 42, which are arranged in the adjustment channel and arranged up and down, and are used to guide the plurality of narrow belts 110 in layers up and down;

[0163] A first width limiting plate 43, which is disposed on a first side of the adjustment channel and is used to limit the narrow belt 110 from the first side;

[0164] The second width limiting plate 44 is disposed on the second side of the adjustment channel, and is used to limit the narrow belt 110 from the second side.

[0165] The first width limiting plate 43 and the second width limiting plate 44 can be adjusted in position in the adjustment seat 41 to adapt to narrow bands 110 of different widths. Through the guiding effect of the plurality of guide rods 42, the spacing between the plurality of narrow bands 110 can be adjusted to be close to contacting each other from top to bottom, and through the clamping effect of the first width limiting plate 43 and the second width limiting plate 44, the upper and lower positions of the plurality of narrow bands 110 can be adjusted to be close to completely overlapping from top to bottom.

[0166] In one embodiment, if Figure 1 , Fig.13 As shown, the composite reinforcing rib production equipment 100 also includes a twisting auxiliary limiting frame 5, which is arranged between the heating flow channel device 3 and the traction twisting device 6, and the twisting auxiliary limiting frame 5 includes:

[0167] The fifth frame 51 is a frame structure and can be made by welding and assembling profiles;

[0168] The limiting seat 52 is arranged on the top of the fifth frame 51 . A limiting hole 53 is arranged in the limiting seat 52 . The narrow band 110 passes through the limiting hole 53 and is limited by the limiting hole 53 , so as to prevent the narrow band 110 output from the heating channel device 3 from rotating.

[0169] After the multiple narrow bands 110 enter the traction and twisting device 6, they are driven by the rotation of the inner tube 64, and the multiple narrow bands 110 between the heating flow channel device 3 and the traction and twisting device 6 will have a tendency to rotate. In order to prevent the multiple narrow bands 110 from winding in the heating flow channel device 3, the multiple narrow bands 110 are restricted by the twisting auxiliary limiting frame 5. The limiting hole 53 is a rectangular hole with a small height. The multiple narrow bands 110 can pass through the limiting hole 53, but cannot rotate, thereby playing a limiting role.

[0170] In one embodiment, if Figure 1 , Figure 2 As shown, the composite reinforcement rib production equipment 100 also includes:

[0171] The cutting device 8 is arranged downstream of the traction and twisting device 6, and is used for cutting the composite reinforcing rib 120 made of the narrow strip 110 according to a preset length.

[0172] The cutting device 8 is provided with rollers and a cutter (not shown in the figure). The composite reinforcing ribs 120 run on the rollers, and the cutter can cut the composite reinforcing ribs 120 according to a preset length, thereby realizing continuous production of the composite reinforcing ribs 120.

[0173] In one embodiment, if Figure 1 , Fig.13 As shown, the composite reinforcing rib production equipment 100 also includes a transition bracket 7, which is arranged between the traction and twisting device 6 and the cutting device 8. A clamping device 71 is arranged in the transition bracket 7. The composite reinforcing rib 120 passes through the clamping device 71 and is limited by the clamping device 71 to prevent the composite reinforcing rib 120 from swinging during cutting.

[0174] The clamping device 71 can be provided with upper and lower corresponding clamping arms, and grooves are provided on the clamping arms. The composite reinforcement rib 120 passes through between the upper and lower clamping arms and is located in the groove. When subjected to force during cutting, it will not cause large up and down jumps or large horizontal swings, thereby maintaining stable operation.

[0175] In one embodiment, if Figure 1 , Fig.14 As shown, casters 130 are provided below the unwinding frame 1, the guide frame 2, the heating flow channel device 3, the twisting auxiliary limiting frame 5, the traction twisting device 6, the transition bracket 7, and the cutting device 8, and can move along the track 140 to facilitate adjustment of the spacing between the various devices when installing the equipment. The casters 130 can be provided with brake devices, and after each device is adjusted to a suitable position, the casters 130 are braked to fix the position of each device.

[0178] In the second step, the narrow belt 110 is unwound from the unwinding frame 1, passed through the guide frame 2 and the cluster frame 4, and connected to the traction rope at the entrance end of the flow channel 33;

[0179] In the third step, the narrow strip 110 passes through the flow channel 33, and the heat radiation of the flow channel 33 completes the heat melting of the narrow strip 110. The traction rope and the narrow strip 110 are pulled through the traction and twisting device 6 for twisting, cooling and shaping, and then transported to the cutting device 8. While pulling, the traction and twisting device 6 performs spiral twisting on the heated and melted narrow strip 110.

[0180] Step 4: Cutting the product into sections by the cutting device 8 according to the set specifications and dimensions;

[0181] In the fifth step, the cut composite reinforcing ribs 120 (plastic fiber steel bars) are post-processed to form continuous fiber reinforced thermoplastic composite reinforcing ribs with specific patterns.
