DETAILED DESCRIPTION

[0036] The technical scheme in the embodiment of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiment of the present invention, all other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the present invention.

[0037] Reference to an "embodiment" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0038] Continuous fiber reinforced thermoplastic composites (CFRT) are composite sheets formed by continuous glass fibers and polypropylene particles (PP) at high temperatures. CFRT sheets have high tensile mechanical properties along the 0° direction of their fibers, and weak tensile mechanical properties along the 90° direction of their fibers. By vertically interlacing the CFRT sheets in the warp and weft directions, and then hot-pressing them, a CFRT composite sheet with bidirectional reinforcement can be obtained. However, during the operation of the weaving machine currently used to weave CFRT sheets, only one sheet can be woven in the weft direction for each weaving operation. Therefore, the weaving process is usually cumbersome, it takes a long time to weave multiple warp sheets and multiple weft sheets, and the overall weaving efficiency is low.

[0039] Based on this, the present invention provides a weaving device, including a weaving mechanism and a clamping mechanism. The weaving mechanism includes an upper pressing component, a lower pressing component and a first driving unit. A plurality of first composite sheets arranged along a first direction are arranged between the upper pressing component and the lower pressing component. The first driving unit drives the upper pressing component and the lower pressing component to move relative to each other, so as to press each first composite sheet into a preset shape, thereby forming a plurality of composite sheet channels arranged along a second direction. The first direction and the second direction are arranged at an angle. The clamping mechanism includes a second driving unit and a plurality of clamping units arranged along the second direction, and the plurality of clamping units correspond one to one to the plurality of composite sheet channels. The second driving unit can drive the plurality of clamping units to reciprocate along the first direction to clamp the plurality of second composite sheets arranged in the second direction, so that the second composite sheets pass through the corresponding composite sheet channels respectively, thereby interlacing and weaving the plurality of first composite sheets and the plurality of second composite sheets at the same time.

[0040] like Figure 1 and Figure 2 As shown, an exemplary embodiment of the present invention provides a weaving device 1. The weaving device 1 includes a weaving mechanism 2 and a clamping mechanism 3. The weaving mechanism 2 includes an upper pressing component 211, a lower pressing component 221 and a first driving unit 23. There is a space between the upper pressing component 211 and the lower pressing component 221 for arranging a plurality of first composite sheets 8 arranged along a first direction. The first driving unit 23 can drive the upper pressing component 211 and the lower pressing component 221 to produce relative movement, so that the upper pressing component 211 and the lower pressing component 221 cooperate to press the plurality of first composite sheets 8 into a preset shape. The preset shape can be, for example, Figure 5 The wavy shape shown. Figure 5 and Figure 6 , adjacent first composite sheets 8 form wave-shaped peaks and troughs arranged alternately to form composite sheet channels 81, and each first composite sheet 8 forms a plurality of composite sheet channels 81 arranged along the second direction. The second direction is set at an angle to the first direction. The angle between the first direction and the second direction can be set according to actual needs. For example, refer to Figure 1 The first direction is the x direction, the second direction is the y direction, and the angle between the first direction and the second direction is 90°.

[0041] like Figure 1 As shown, the clamping mechanism 3 includes a second driving unit 31 and a plurality of clamping units 32 arranged along the second direction. The plurality of clamping units 32 correspond one by one to the plurality of composite sheet channels 81 formed by the first composite sheet 8. The second driving unit 31 drives the plurality of clamping units 32 to reciprocate along the first direction to clamp the plurality of second composite sheets arranged in the second direction and make each second composite sheet pass through the corresponding composite sheet channel 81.

[0042] refer to Figure 1 and Figure 2 In one embodiment, the weaving mechanism 2 includes a weaving upper pressing plate 21 and a weaving lower pressing plate 22. The upper pressing assembly 211 is connected to the bottom surface of the weaving upper pressing plate 21, and the top surface of the weaving upper pressing plate 21 is connected to the first driving unit 23. Exemplarily, the upper pressing assembly 211 is detachably connected to the bottom surface of the weaving upper pressing plate 21, and the first driving unit 23 is drivingly connected to the weaving upper pressing plate 21. Thus, the first driving unit 23 can drive the weaving upper pressing plate 21 to move up and down, so as to drive the upper pressing assembly 211 to move up and down. In this embodiment, the lower pressing assembly 221 is connected to the top surface of the weaving lower pressing plate 22, and the connection method can be, for example, a detachable connection. Thus, when the lower pressing assembly 221 is damaged, the lower pressing assembly 221 can be replaced separately to save maintenance costs.

[0043] refer to Figure 2In one embodiment, the first driving part 23 can be, for example, a driving cylinder, and the number of driving cylinders can be, for example, two. The driving cylinder is connected to the top surface of the frame 12 through a fixed seat 231, so that the first driving part 23 can stably drive the weaving upper pressing plate 21 to move smoothly. Exemplarily, the first driving part 23 is provided with a fisheye joint 232, and the fisheye joint 232 is connected to one end of the piston rod of the driving cylinder. The number of fisheye joints 232 is consistent with the number of the first driving part. The top surface of the weaving upper pressing plate 21 is provided with a connecting seat 212, and the fisheye joint 232 is connected to the connecting seat 212 through a pin 233, thereby realizing the connection between the first driving part 23 and the weaving upper pressing plate 21. In this embodiment, the fisheye joint 232 is matched with the driving cylinder to ensure that a certain degree of freedom is released during the cylinder driving process, so that the weaving upper pressing plate 21 always remains horizontal during the up and down movement. In another embodiment, the first driving part 23 is a linear module, which can drive the weaving upper pressing plate 21 to move up and down, so as to drive the upper pressing assembly 211 to move up and down, so that the upper pressing assembly 211 cooperates with the lower pressing assembly 221 to press the plurality of first composite sheets 8 into a preset shape. The linear module can more accurately control the moving speed and moving position of the upper pressing assembly 211, thereby improving the control accuracy of the weaving mechanism 2.

[0044] For example, the shape of the braided upper pressing plate 21 is rectangular, and may also be trapezoidal, rhombus-shaped, circular, etc., which is not limited in this embodiment. Figure 2 When the upper braiding plate 21 is rectangular, through holes (not shown) are provided at the four corners of the rectangle. Linear bearings 213 are provided at each through hole of the upper braiding plate 21 to improve the smoothness of the upper braiding plate 21 during the up and down movement.

[0045] Continue to refer Figure 2 For example, the shape of the braided lower pressing plate 22 is consistent with the shape of the braided upper pressing plate 21 to improve the fit between the braided lower pressing plate 22 and the braided upper pressing plate 21. The shape of the braided lower pressing plate 22 can be, for example, a rectangle, or a trapezoid, a rhombus, a circle, etc., which is not limited in this embodiment. Figure 1 Shown and combined Figure 2 When the weaving lower pressing plate 22 is rectangular, a guide post 222 is provided at the corresponding position of the linear bearing 213 provided on the weaving lower pressing plate 22 and the weaving upper pressing plate 21. The linear bearing 213 is sleeved on the outside of the guide post 222, and cooperates with the guide post 222 to realize the relative movement between the weaving upper pressing plate 21 and the weaving lower pressing plate 22. In this way, the position displacement of the weaving upper pressing plate 21 during the up and down movement can be avoided, and the friction force generated by the weaving upper pressing plate 21 during the up and down movement can be reduced, which is conducive to ensuring the weaving efficiency of the weaving mechanism 2.

[0046] like Figure 1As shown, in one embodiment, the second driving part 31 is drivingly connected to a plurality of clamping parts 32 arranged along the second direction, and the second driving part 31 can be, for example, a linear module. Thus, the linear module can accurately control the movement speed and movement distance of each clamping part 32 to accurately clamp the corresponding second composite sheet. The second driving part 31 can also be a driving cylinder or other driving structure that can drive each clamping part 32 to reciprocate in the first direction.

[0047] For example, the number of the clamping parts 32 can be determined according to the actual needs in production. The number of the clamping parts 32 can be set to an even number, such as 4 groups, 8 groups, 14 groups, etc. For example, referring to Figure 1 , the number of the clamping parts 32 is set to 6 groups. Figure 5 The first composite sheet 8 woven twice adjacently by the weaving mechanism 2 has a preset shape symmetrical in the connecting part, that is, it can ensure that the crests and troughs of the first woven fibers 8 at the connecting parts of the two woven products alternate, thereby forming a single composite sheet channel 81 for the second composite sheet to pass through, thereby ensuring the weaving effect of the weaving mechanism 2.

[0048] refer to Figure 7 Combined with Figure 8 In one embodiment, the upper pressing assembly 211 includes a plurality of first braiding head groups arranged in a first direction, and each first braiding head group includes a plurality of first braiding heads 241 arranged in a second direction. The lower pressing assembly 221 includes a plurality of second braiding head groups arranged in a first direction, and each second braiding head group includes a plurality of second braiding heads 242 arranged in a second direction. The plurality of second braiding head groups correspond one-to-one to the plurality of first braiding head groups, and the plurality of first braiding heads 241 in each first braiding head group correspond one-to-one to the plurality of second braiding heads 242 in the corresponding second braiding head group. Figure 7 As shown, the first direction may be, for example, the x-direction, and the second direction may be, for example, the y-direction. Each first weaving press head 241 and the corresponding second weaving press head 242 constitute a press head assembly 24, and the first weaving press head 241 and the second weaving press head 242 in the same press head assembly 24 are staggered in the second direction. In this way, the first weaving press head 241 can press down one end of the first composite sheet 8, and the second weaving press head 242 can lift the other end of the first composite sheet 8 to bend the first composite sheet 8 when the first weaving press head 241 and the second weaving press head 242 move relative to each other. In a row of press head assemblies 24, the staggered directions of adjacent press head assemblies 24 are opposite. In this way, refer to Figure 1 , Figure 7 and Figure 8The first direction is the x direction, and the second direction is the y direction. When the upper pressing component 211 and the lower pressing component 221 produce relative movement, multiple first composite sheets 8 arranged along the first direction can form multiple composite sheet channels 81 arranged along the second direction.

[0049] refer to Figure 7 and Figure 8 In this embodiment, the first braided pressing head 241 is U-shaped, and the first braided pressing head 241 can be formed by bending a rod-shaped member, and the material of the rod-shaped member can be, for example, stainless steel, plastic, rubber, etc. In another embodiment, the first braided pressing head 241 is a rectangular parallelepiped, and the material of the rectangular parallelepiped can be, for example, plastic, stainless steel, rubber, etc.

[0050] refer to Figure 7 and Figure 8 In this embodiment, the second braided pressing head 242 is in an inverted U shape, and the second braided pressing head 242 can be formed by bending a rod-shaped member, and the material of the rod-shaped member can be, for example, stainless steel, plastic, rubber, etc. In another embodiment, the second braided pressing head 242 is in a rectangular parallelepiped, and the material of the rectangular parallelepiped can be plastic, stainless steel, rubber, etc.

[0051] In this embodiment, in two adjacent rows of press head assemblies 24, the staggered directions of the press head assemblies 24 at corresponding positions are opposite. Thus, after being bent by the two adjacent rows of press head assemblies 24, the directions of the bends formed by the two adjacent first composite sheets 8 are opposite. Thus, after being pressed down by a row of press head assemblies 24, a composite sheet passage 81 can be formed in the first direction for the second composite sheet to pass through.

[0052] refer to Figure 1 In one embodiment, the clamping portion 32 includes a rod-shaped member 321 and a clamping member 322. The clamping member 322 is connected to one end of the rod-shaped member 321, and the clamping member 322 is used to clamp the end of the second composite sheet. In this embodiment, the rod-shaped member 321 and the clamping member 322 can be detachably connected. Therefore, when the clamping member 322 is damaged, only the clamping member 322 needs to be replaced without replacing the rod-shaped member 321, which is conducive to reducing maintenance costs.

[0053] refer to Figure 1In one embodiment, the clamping mechanism 3 includes a clamping portion fixing seat 33. The clamping portion fixing seat 33 includes two vertical plates for fixing the rod-shaped member 321 and a bottom plate arranged perpendicular to the vertical plates. Through holes matching the rod-shaped member 321 are arranged on the two vertical plates for the rod-shaped member to pass through, so as to improve the stability of each clamping portion 32 during the reciprocating motion. The bottom plate is fixedly connected to the vertical plate, and the bottom of the bottom plate is fixedly connected to the second driving portion 31. Thus, the second driving portion 31 can drive the clamping portion fixing seat 33 to reciprocate in the first direction, thereby driving each clamping portion to reciprocate smoothly in the first direction.

[0054] In one embodiment, the rod-shaped member 321 is a hollow rod, and an air pipe joint 323 is provided at one end of the hollow rod away from the clamping member 322. The air pipe joint 323 is used to connect to a pressure source (not shown in the figure), and the pressure source can drive the clamping member to open and close. Exemplarily, a clamping cylinder (not shown in the figure) is provided in the hollow rod. One end of the piston rod of the clamping cylinder is connected to the clamping member 322. The clamping member 322 includes an upper clamping member and a lower clamping member, and the upper clamping member and the lower clamping member are hinged. One end of the upper clamping member and the lower clamping member is connected to one end of the piston rod of the clamping cylinder, and the other end of the upper clamping member and the lower clamping member extends out of the rod-shaped member 321 for clamping the second composite sheet. When the pressure source vents air into the hollow rod, the piston rod of the clamping cylinder extends, and the clamping member 322 loosens the end of the second composite sheet; when the pressure source extracts the air in the hollow rod, the piston rod of the clamping cylinder retracts, and the clamping member 322 clamps the end of the second composite sheet. In this way, by controlling the pressure source to control the movement of the clamping cylinder piston rod, efficient control of the clamping member 322 can be achieved, thereby causing the clamping member 322 to clamp or loosen the end of the second composite sheet.

[0055] refer to Figure 3 and Figure 4 In one embodiment, the weaving device 1 includes a cutting mechanism 4. In this embodiment, the cutting mechanism 4 is used to cut the ends of each first composite sheet 8 before the first composite sheet 8 enters the weaving mechanism 2. The clamping mechanism 3, the weaving mechanism 2 and the cutting mechanism 4 are arranged in sequence along the first direction, so that the second composite sheet first enters the cutting mechanism 4 for cutting, and then the second composite sheet is clamped by the clamping mechanism 3 and enters the weaving mechanism 2 for weaving.

[0056] refer to Figure 4In one embodiment, the cutting mechanism 4 includes a pressing plate 41, a cutting plate 42 and a cutter 43. The pressing plate is used to press a plurality of second composite sheets so that each clamping portion 32 clamps the corresponding second composite sheet. In the first direction, the cutter 43 is located between the pressing plate 41 and the weaving mechanism 2, and the cutting plate 42 cooperates with the cutter 43 to cut each second composite sheet pressed by the pressing plate 41. Thus, the cutter 43 can uniformly cut the plurality of second composite sheets pressed by the pressing plate 41, so that the ends of the plurality of second composite sheets are neat. Among them, a plurality of openings 421 are provided on one side of the cutting plate 42 close to the weaving mechanism 2, and each opening 421 matches each second composite sheet. The plurality of openings 421 provided on one side of the cutting plate 42 can place the ends of each neatly cut second composite sheet in each opening 421, which is conducive to each clamping portion 32 accurately and quickly clamping the ends of the second composite sheet.

[0057] refer to Figure 3 and Figure 4 In one embodiment, the cutting mechanism 4 also includes a cutting drive unit 44 and a pressing drive unit 45. The pressing drive unit 45 is used to drive the pressing plate 41 and the cutting plate 42 to produce relative movement, thereby pressing the end of the second composite sheet. After the pressing plate 41 presses the end of the second composite sheet, the cutting drive unit 44 is used to drive the cutter 43 and the cutting plate 42 to produce relative movement, thereby neatly cutting the end of the second composite sheet. Exemplarily, two cutting drive units 44 are provided, and one pressing drive unit 45 is provided. The connection method between the cutting drive unit 44 and the pressing plate 41 is the same as the connection method between the above-mentioned first drive unit 23 and the weaving upper pressing plate 21.

[0058] In this embodiment, the cutting drive unit 44 can be a drive cylinder, a linear module or other structure capable of driving the cutter 43 to move up and down. The clamping drive unit 45 can be a drive cylinder, a linear module or other structure capable of driving the clamping plate 43 to move up and down.

[0059] refer to Figure 1 and Figure 3 In one embodiment, the braiding device includes a frame 12 and a base 11, which are used to support and fix the various parts of the braiding device 1 to improve the structural stability of the braiding device 1.

The transverse partition is fixedly connected to the withdrawal lower pressing plate 722 to provide support for the withdrawal lower pressing plate 722. The longitudinal partition is arranged in the middle of the transverse partition and is fixedly connected to the transverse partition.

The two ends of the bottom plate of the frame 73 are connected to the two side plates, the middle of the bottom plate is connected to the longitudinal partition, and the lower part of the bottom plate is connected to the slider 14, so that when the slider 14 slides, it can drive the retracting pressing part 72 to move.

[0067] refer to Figure 1In one embodiment, the weaving device 1 includes a partition structure 15. In the second direction, the partition structure 15 is arranged between the withdrawal mechanism 7 and the weaving mechanism 2. After the plurality of first composite sheets 8 pass through the tensioning structure 6 and the withdrawal mechanism 7 in sequence, the plurality of first composite sheets 8 pass through the partition structure 15 and then enter the weaving mechanism 2 for weaving. The partition structure 15 is a rectangular frame, which is composed of a top plate, a bottom plate, two side plates and a plurality of longitudinal partitions. Exemplarily, the shapes of the various parts of the sheet materials constituting the partition structure 15 are all rectangular, and the plurality of rectangular partitions are arranged in parallel in the rectangular frame according to a preset interval. The preset interval can be set according to the size of the second composite sheet. When the plurality of first composite sheets 8 pass through the partition structure 15, each adjacent first composite sheet can be separated by the partition, so that the entanglement between the first composite sheets can be effectively avoided, thereby ensuring the weaving efficiency. In this embodiment, the partition structure 15 is fixedly connected to the frame 12 through a support member, and the support member is composed of a rectangular top surface and a rectangular side surface perpendicular to each other and two triangular side surfaces parallel to each other, which can improve the stability of the partition structure 15.

[0068] The specific working process of the weaving device 1 of the present invention is as follows: the operator allows multiple first composite sheets 8 to pass through the tensioning structure 6, then through the withdrawal mechanism 7, and after being separated by the partition structure 15, enter the weaving mechanism 2, lay flat on the down-pressing assembly 221, and extend from the upper side of the roller 5 to the winding device. The ends of the multiple first composite sheets 8 are pasted on the winding device. The weaving upper pressing plate 21 of the weaving mechanism 2 presses down, so that the multiple first composite sheets 8 have wavy bends, and the multiple first composite sheets 8 form multiple composite sheet channels 81. The cutting mechanism 4 presses the ends of the multiple second composite sheets, and the cutting plate 42 cooperates with the cutting knife 43 to cut the ends of the multiple second composite sheets neatly. The second driving unit 31 drives each clamping unit 32 to move in the first direction, pass through the corresponding composite sheet channel 81 to clamp the end of the second composite sheet and drive the second composite sheet to pass through the corresponding composite sheet channel 81. The weaving upper pressing plate 21 moves upward, and the retracting and pressing part 72 of the retracting mechanism 7 presses the plurality of first composite sheets 8. The third driving part 71 drives the retracting mechanism to move toward the side close to the tensioning structure 6, so that the plurality of first composite sheets 8 and the plurality of second composite sheets are closely interlaced and woven to form a composite sheet product. The composite sheet product formed after each weaving is rolled up by the winding device.
