Description

Technical Field

[0001] The present application generally relates to the technical field of prepreg tape production, and more specifically to a laminating device. Background Art

[0002] Prepreg tape refers to a tape-shaped prepreg made of parallel continuous fibers or unidirectional fabrics impregnated with resin. Prepreg tape is a technology widely used in many industries, and plays an important role in aerospace, automotive manufacturing, construction and sports equipment. The advantages of prepreg tape lie not only in its material properties, but also in the flexibility of manufacturing process. Prepreg tape can be customized according to different needs to meet the manufacturing needs of various complex shapes. At the same time, prepreg tape can be mass-produced through automated equipment to improve production efficiency and reduce costs.

[0003] The prepreg production line process uses an extruder to transport the resin through a flow channel to a high-precision impregnation mold for impregnation of fibers and then shapes and compounds them. At present, most prepregs on the market with high surface quality requirements are produced by discharging from the top. However, the existing extruder impregnation molds on the market all have single-port discharge. The resin film extruded by the impregnation mold is easily broken after being disturbed, resulting in poor prepreg products. In addition, the amount of extruded resin glue and flow rate per unit time are constant values, the adjustable range is narrow, and the use is limited.

[0060] First embodiment

[0061] See also Figures 1 to 3 , the coating device 1 includes a diverter 11, a mold 21, a first adjustment component 31 and a second adjustment component 41. Specifically, the diverter 11 has a feed port 11a and a branch port 11b that are interconnected. The feed port 11a is used to connect to the extruder. The number of branch ports 11b is at least two and they are located below the feed port 11a. The branch ports 11b are arranged along the vertical direction DH, and the adjacent branch ports 11b are spaced apart in the horizontal direction. Further, the mold 21 is located below the diverter 11 and connected to the diverter 11. The mold 21 has a flow channel 21a corresponding to the position of the branch ports 11b one by one, and one end of the branch port 11b away from the feed port 11a is correspondingly connected to the flow channel 21a. The flow channel 21a is arranged along the vertical direction DH, and one end of the flow channel 21a away from the branch port 11b is connected to the external environment to discharge the material for coating. The first adjustment component 31 is arranged in the horizontal direction, and the first adjustment component 31 includes a first blocking member 32 located above the branch material port 11b, and the first blocking member 32 is movably connected to the diverter 11 in the horizontal direction to control the opening and closing of the branch material port 11b, thereby adjusting the flow of the flow channel 21a in the horizontal direction. The second adjustment component 41 is located below the first adjustment component 31 and is connected to the mold 21. The second adjustment components 41 are arranged in pairs along the second horizontal direction D2, and adjacent second adjustment components 41 are spaced apart along the second horizontal direction D2. The second adjustment component 41 includes a second blocking member 43, and the second blocking member 43 is movably connected to the flow channel 21a along the second horizontal direction D2 to adjust the size of the flow channel 21a along the second horizontal direction D2.

[0062] According to the coating device 1 of the present application, it has at least two branch material ports 11b and corresponding flow channels 21a. According to the use requirements, the coating device 1 can be changed into a conventional single-flow channel discharge coating or a multi-flow channel discharge coating, and the flexibility of use is improved. Moreover, when coating with multiple flow channels, if one of the coating channels is broken, the other flow channels can fill the broken position to prevent the prepreg tape from having defects such as no glue or less glue. In addition, the coating device 1 can adjust the glue output from multiple positions, and can adapt to more product and application scenario requirements.

[0063] See also Figure 1 and Figure 2 , the diverter 11 can be configured to be detachably connected to the mold 21. For example Figure 1 and Figure 2 In the embodiment, the diverter 11 is connected to the mold 21 via a plurality of first fasteners 12 .

[0064] It should be noted that the number of flow channels 21a is at least two, for example, two, three or even more. Adjacent flow channels 21a are spaced along the first horizontal direction D1, and the first horizontal direction D1 is perpendicular to the second horizontal direction D2. The upper end of the flow channel 21a is connected to the corresponding branch material port 11b, and the lower end of the flow channel 21a is connected to the external environment. For example Figures 1 to 3 In the embodiment, the number of the flow channels 21a is two and they are spaced apart along the first horizontal direction D1. It can be understood that the number of the branch material ports 11b is two and they are spaced apart along the first horizontal direction D1.

[0065] The specific structure of the laminating device 1 is introduced below with reference to the illustrated embodiment.

[0066] See also Figure 1 and Figure 3 The mold 21 includes a first flattening plate 22, an intermediate flattening plate 23, and a second flattening plate 24 arranged in sequence in a first horizontal direction D1. Specifically, the first flattening plate 22 and the intermediate flattening plate 23 form a first flow channel, and the second flattening plate 24 and the intermediate flattening plate 23 form a second flow channel. The upper ends of the first flow channel and the second flow channel are respectively connected to the corresponding branch material ports 11b, and the lower ends of the first flow channel and the second flow channel are connected to the external environment. Preferably, the intermediate flattening plate 23 is detachably connected to the first flattening plate 22 and the second flattening plate 24. For example Figure 1 In the embodiment, the first flattening plate 22 can be connected to the middle flattening plate 23 by a plurality of second fasteners 13, and the plurality of second fasteners 13 are arranged roughly in an arc shape to ensure the connection strength between the first flattening plate 22 and the middle flattening plate 23. Figure 3 The second flattening plate 24 and the first flattening plate 22 are roughly symmetrically arranged relative to the middle flattening plate 23, that is, the second flattening plate 24 and the middle flattening plate 23 can also be connected by a plurality of second fasteners 13 arranged roughly in an arc shape.

[0067] See also Figure 2 and Figure 3 , the first adjustment components 31 are arranged in pairs, and the adjacent first adjustment components 31 are spaced and opposite to each other along the first horizontal direction D1. Specifically, the first adjustment components 31 further include a first operating member 33, and the first operating member 33 is arranged along the first horizontal direction D1. The first operating member 33 is pivotally connected to the first blocking member and the diverter 11 around the first horizontal direction D1 to drive the first blocking member 32 to move along the first horizontal direction D1. For example Figure 3 In the embodiment, the number of the first blocking members 32 is two and they are spaced apart along the first horizontal direction D1, and the first blocking members 32 can block the communication between the feed port 11a and the branch port 11b. Figure 3 For the coating device 1 shown, when one of the first blocking members 32 completely blocks the connection between the feed port 11a and the branch port 11b, and the other first blocking member 32 adjusts the connection size between the feed port 11a and the branch port 11b, the coating device 1 is a single-channel discharge coating. When both first blocking members 32 do not completely block the connection between the feed port 11a and the branch port 11b, the coating device 1 is a double-channel discharge coating. Further, the diverter 11 can be provided with a mounting base suitable for the first operating member 33, for example, the first operating member 33 is configured as a rod-shaped member arranged along the first horizontal direction D1, and there is an adaptive threaded structure between the first operating member 33 and the mounting base, the first blocking member 32 is located inside the diverter 11 and is movably connected to the diverter along the first horizontal direction D1, and when the first operating member 33 is rotated, the first blocking member 32 moves along the first horizontal direction D1 without rotating under the drive of the first operating member 33. Figure 3 The closer the first blocking member 32 is to the middle flattening plate 23 along the first horizontal direction D1, the smaller the flow rate actually entering the branch material port 11b from the material port 11a and finally reaching the flow channel 21a, and vice versa, the larger the flow rate is, thereby achieving the technical purpose of the first regulating component 31 regulating the flow rate of the flow channel 21a along the first horizontal direction D1.

[0068] See also Figure 1 and Figure 3 The second adjustment assembly 41 further includes a second operating member 42, which is arranged along the second horizontal direction D2. The second operating member 42 is pivotally connected to the mold 21 and the second blocking member 43 around the second horizontal direction D2 to drive the second blocking member 43 to move along the second horizontal direction D2. Specifically, for example Figure 1 and Figure 3 In the embodiment, the second blocking member 43 is located inside the mold 21 and is movably connected to the mold 21 along the second horizontal direction D2. Figure 1In the embodiment, the second adjustment components 41 are arranged in pairs, and adjacent second adjustment components 41 are spaced apart along the second horizontal direction D2. Furthermore, the second operating member 42 is configured as a screw rod arranged in the second horizontal direction D2, and the second adjustment component 41 further includes a transmission member 44, and the transmission member 44 is connected to the second blocking member 43. Further, the transmission member 44 is movably connected to the mold 21 along the second horizontal direction D2 to drive the second blocking member 43 to move along the second horizontal direction D2. The transmission member 44 has a sliding portion 44a, and the mold 21 has a first fixed portion 21e suitable for the sliding portion 44a. For example, the sliding portion 44a is configured as a slider, and the first fixed portion 21e is configured as a slide rail suitable for the slider. Accordingly, the transmission member 44 and the screw rod have an adaptive transmission thread structure, and when the user rotates the second operating member 42, the transmission member 44 moves relative to the mold 21 along the second horizontal direction D2, so that the second blocking member 43 moves along the second horizontal direction D2 following the transmission member 44. For example Figure 1 In the embodiment, if the two second blocking members 43 move along the second horizontal direction D2 toward the middle position close to the mold 21, the size of the flow channel 21a along the second horizontal direction D2 is reduced, that is, the actual glue discharge size along the second horizontal direction D2 is reduced, otherwise it is increased, thereby achieving the technical purpose of adjusting the size of the flow channel 21a along the second horizontal direction D2. It is easy to imagine that the aforementioned first operating member 33 and the second operating member 42 can also be equipped with an automated drive, assisted by a control device, so as to achieve the technical purpose of automatically adjusting the flow rate in the flow channel 21a along the first horizontal direction D1 and automatically adjusting the size of the flow channel 21a along the second horizontal direction D2.

[0069] Please continue reading Figure 3, the flow channel 21a includes a straight section 21b, a mixing section 21c and an extrusion section 21d. Specifically, the mixing section 21c is located below the straight section 21b and is connected to the straight section 21b, and the cross-sectional area of ​​the mixing section 21c is configured to decrease from top to bottom. The extrusion section 21d is connected to the end of the mixing section 21c away from the straight section 21b and is connected to the external environment. Moreover, the cross-sectional area of ​​the extrusion section 21d is configured to be no larger than the cross-sectional area of ​​the connection between the mixing section 21c and the extrusion section 21d. Further, the laminating device 1 also includes a third operating member 14, the first flattening plate 22 and the second flattening plate 24 both include a second fixed portion 22a and a deformation portion 22b, and the third operating member 14 is pivotally connected to the second fixed portion 22a and the deformation portion 22b. It should be noted that, under the operation of the user, or in other words, when the user operates the automatic driving member connected to the third operating member 14, the third operating member 14 can drive the deformation portion 22b to abut against the intermediate flattening plate 23 along the first horizontal direction D1 to adjust the size of the extrusion section 21d along the first horizontal direction D1. In other words, it is to adjust the thickness of the actual discharge film. Further, the deformation portion 22b is located below the second fixed portion 22a, and the axial direction of the third operating member 14 is inclined relative to the vertical direction D1 and the first horizontal direction D1. In addition, in order to ensure the smoothness of the flow of raw materials (such as resin) in the flow channel 21a, a transition fillet is provided at the connection between the mixing section 21c and the straight section 21b and the extrusion section 21d.

[0070] According to the coating device 1 of the present application, when the fluid is discharged from the extruder and enters the branch outlet 11b from the outlet 11a ( Figure 3 The arrow in the figure indicates the flow direction of the fluid), and the position of the first blocking member 32 can be adjusted to accurately control the distribution amount of the fluid in each flow channel 21a. Due to the adjustment of the first regulating component 31, the fluid forms a pressure difference between the upper and lower sides of the first blocking member 32. After the fluid passes through the first blocking member 32, not only the actual flow rate changes, but also the flow rate of the fluid is accelerated. When the fluid enters the straight section 21b, under the extrusion of the first flattening plate 22, the middle flattening plate 23 and the second flattening plate 24, the flow rate and flow rate of the fluid in the straight section 21b are guaranteed, which can eliminate the turbulent flow of the fluid and make the fluid melt and mix evenly with uniform temperature. Through the distribution of fluid flow rate and flow velocity of multiple flow channels 21a, the fluid enters the mixing section 21c. Since the caliber of the mixing section 21c decreases from top to bottom, and the caliber of the extrusion section 21d is also sharply reduced relative to the mixing section 21c and / or the straight section 21b, the fluid can be fully melted and mixed at high speed and high pressure, so that the fluid can be smoothly extruded at the extrusion section 21d. In addition, the caliber of the extrusion section 21d is adjustable, which eliminates the uneven thickness, erratic size deviation, and lack of glue in the existing single glue outlet (or ordinary glue outlet) due to the influence of tension, gravity or other external forces.

[0071] Second embodiment

[0072] See also Figures 4 to 6 , an extrusion device 2 is provided. Compared with the first embodiment, the difference is that the number of the flow channels 21a is three, and the first adjustment components 131 are arranged along the second horizontal direction D2 and correspond to the branch material ports 11b one by one. Figure 5 , adjacent first adjustment components 131 are spaced apart along the first horizontal direction D1. The first adjustment component 131 includes a first operating member 133 and a first blocking member 132. The first operating member 133 is arranged along the second horizontal direction, and the first operating member 133 is pivotally connected to the first blocking member 132 and the diverter 11 around the second horizontal direction D2 to drive the first blocking member 132 to move along the second horizontal direction D2.

[0073] Also, see Figure 6 The number of the intermediate flattening plates 23 is two and they are spaced apart along the first horizontal direction D1. A flow channel 21a is formed between adjacent intermediate flattening plates 23, and the intermediate flattening plates 23 are detachably connected to the first flattening plates 22 and / or the second flattening plates 24 adjacent to each other along the first horizontal direction D1. Figure 6 In the embodiment, one of the intermediate flattening plates 23 is detachably connected to the first flattening plate 22 and forms a flow channel 21 a, and the other intermediate flattening plate 23 is detachably connected to the second flattening plate 24 and forms a flow channel 21 a.

[0074] Compared with the traditional single-outlet extrusion equipment, the coating device of the present application can extrude films or fluids of different thicknesses, different flow rates, and different widths (i.e., the dimensions along the second horizontal direction D2) at different outlets (i.e., the place where the flow channel 21a is connected to the external environment). The coating device of the present application can be transformed into a conventional single-outlet discharge device or a multi-outlet discharge device (such as a double-outlet or triple-outlet discharge device as shown in the figure). When one of the coating layers is broken, the other layer can fill the broken film position to prevent the prepreg tape from having defects such as no glue or less glue. It also has a wide adjustable range and can adapt to more product and application scenario requirements.
