However, it will be apparent to one of ordinary skill in the art that the present application can be practiced without some of these specific details.

[0038] The applicant finds that the manufacturing process of many devices will use composite fiber materials, for example, glass fiber composite materials will be used when making wind turbine blades. Before using the composite material, the fiber material needs to be immersed in the resin to improve the structural performance of the composite material. The process of immersing the fiber material in the resin usually adopts manual mode. The process of manual operation mainly depends on the experience of the operator, and it is difficult to accurately control the amount of resin impregnated in the fiber material, and defects such as bubbles, rich resin area or dry yarn are prone to occur. In addition, the composite material usually adopts the form of multi-layer fiber material impregnated with resin, and the different fiber materials need to be arranged in staggered layers, and manual operation will cause the staggered layers to be non-standard and the operation efficiency to be low. Considering that the resin will volatilize harmful gases such as styrene, which may directly endanger the health of workers and pollute the environment, strict protection is required.

[0039] In view of the above analysis, the applicant proposes a multi-layer automatic staggered layer device. The multi-layer automatic staggered layer device comprises a feeding mechanism, a heating mechanism, a resin immersion mechanism, a glue amount control mechanism and a winding mechanism. The feeding mechanism can release multiple layers of fiber cloth respectively, and by moving the movable cloth roll shaft in the second direction, the multiple layers of fiber cloth can form a more accurate staggered layer of multiple layers of fiber cloth. The multiple layers of fiber cloth will enter the heating mechanism for heating. The immersion roller of the resin immersion mechanism immerses the heated multiple layers of fiber cloth in the resin, so that each layer of fiber cloth can be fully immersed in the resin. The multiple layers of cloth pass through the gap between the glue scraping rollers of the glue amount control mechanism, and the excess resin is scraped off, and by allowing at least two glue scraping rollers to approach or move away, the amount of resin on the multiple layers of cloth is adjusted. The winding mechanism can wind the scraped multiple layers of cloth for subsequent use. The multi-layer automatic staggered layer device of the embodiment of the present application can realize multi-layer cloth feeding, multi-layer automatic staggered layer, multi-layer heating, multi-layer automatic cloth immersion and multi-layer automatic winding, thereby improving the automation, controllability and standardization of the cloth immersion operation.

[0041] Please refer to Figures 1 to 8The embodiment of the present application provides a multi-layer automatic staggered layer device, which comprises a feeding mechanism 1, a heating mechanism 2, a resin soaking mechanism 3 and a glue amount control mechanism 4.

[0042] The multi-layer automatic staggered layer device of the embodiment of the present application is used for forming multi-layer cloth with a preset staggered layer width, soaking the multi-layer cloth into resin, and scraping off the excess resin according to a preset resin amount, so as to obtain multi-layer cloth with a preset resin amount and a preset staggered layer width. It can be understood that in the process, the fiber cloth is conveyed and sequentially passes through each mechanism of the multi-layer automatic staggered layer device of the embodiment of the present application, so that the position passed first corresponds to the upstream of the multi-layer automatic staggered layer device of the embodiment of the present application, and the position passed last corresponds to the downstream of the multi-layer automatic staggered layer device of the embodiment of the present application. It can be understood that the conveying direction of the fiber cloth is not fixed and can be changed during conveying. When the multi-layer automatic staggered layer device of the embodiment of the present application is placed on a horizontal plane, the first direction D1 can correspond to the vertical direction, and the second direction D2 can correspond to a certain horizontal direction. Exemplarily, the fiber cloth can be glass fiber cloth or carbon fiber cloth.

[0043] Continuing to refer to Figure 2 and Figure 3 , and combining Figure 1 , the feeding mechanism 1 is used for feeding and loading the multi-layer fiber cloth, at this time, each layer of fiber cloth is wound into a roll, and each roll of fiber cloth is arranged on the movable cloth roll shaft 11 of one of the feeding mechanisms 1. The plurality of movable cloth roll shafts 11 extend along the second direction D2, so that the fiber cloth on the plurality of movable cloth roll shafts 11 can be fed and loaded in substantially the same direction. The plurality of movable cloth roll shafts 11 are arranged in parallel along the first direction D1, so that the fiber cloth on the plurality of movable cloth roll shafts 11 can be arranged in layers along the second direction D2. It can be understood that the multi-layer fiber cloth fed and loaded does not necessarily contact and fit as a whole.

[0044] The movable cloth spool 11 can be moved along the second direction D2, so that the positions of the different layers of the fiber cloth along the second direction D2 are staggered. The positions of the movable cloth spools 11 along the second direction D2 can be adjusted according to the preset staggered layer width, so that the staggered layer width of each fiber cloth is equal to the preset staggered layer width. It can be understood that there may be an inevitable error between the actual staggered layer width of each fiber cloth and the preset staggered layer width.

[0045] With reference to the above Figure 4 , and in combination with Figure 1 , the fiber cloth with the adjusted staggered layer width is conveyed to the heating mechanism 2 for heating, so that the fiber cloth can more easily adhere to the resin. During the conveying of the fiber cloth to the heating mechanism 2, the staggered layer width between the fiber cloths needs to be kept unchanged. When the multiple layers of fiber cloth pass through the heating mechanism 2, the multiple layers of fiber cloth can be kept separate and heated respectively, or can be attached together and heated together.

[0046] With reference to the above Figure 6 , and in combination with Figure 1 , the heated fiber cloth is conveyed to the resin impregnation mechanism 3 to adhere the resin to the fiber cloth. The resin impregnation mechanism 3 includes multiple impregnation rollers 31, and the impregnation pipes extend along the second direction D2. The multiple impregnation rollers 31 are arranged correspondingly to the movable cloth spools 11, so that each impregnation roller 31 can correspond to one layer of fiber cloth. The multiple impregnation rollers 31 are arranged in parallel along the first direction D1, so that each layer of fiber cloth can be inserted into the resin, thereby enabling each layer of fiber cloth to sufficiently and excessively adhere to the resin.

[0047] With reference to the above Figure 7 , and in combination with Figure 1 , the fiber cloth with the adhered resin is conveyed to the glue amount control mechanism 4 to remove the excessively adhered resin. After the resin is impregnated, the multiple layers of fiber cloth with the adhered resin can be attached together and bonded by the resin into a multiple layer cloth with a certain staggered layer width, and the multiple layer cloth still has excess resin adhered thereto. The multiple layer cloth passes between the at least two glue scraping rollers 41, and at this time the glue scraping rollers 41 scrape the excess resin on the multiple layer cloth.

[0048] The at least two glue scraping rollers 41 are movably arranged so that the two glue scraping rollers 41 can be close to or away from each other to adjust the gap size between the glue scraping rollers 41. The gap width between the glue scraping rollers 41 and the total thickness of the fiber cloth are determined in consideration of the total thickness of the fiber cloth, and the difference between the gap width and the total thickness of the fiber cloth is positively correlated with the amount of remaining resin on the multi-layer cloth, so that the amount of resin on the multi-layer cloth can be adjusted by adjusting the width of the gap between the glue scraping rollers 41. Therefore, the width of the gap between the glue scraping rollers 41 can be adjusted according to the preset amount of resin, so that the amount of remaining resin on the multi-layer cloth after scraping is equal to the preset amount of resin. It can be understood that there may be an inevitable error between the amount of remaining resin and the preset amount of resin.

[0049] With reference to Figure 8 , and in combination with Figure 1 , the multi-layer cloth after scraping is conveyed to the winding mechanism 5 and wound on the winding shaft 51 for subsequent use of the multi-layer cloth. For example, the multi-layer cloth can be used to manufacture blades of a wind turbine.

[0050] In the process of manufacturing the multi-layer cloth using the multi-layer cloth automatic staggered layer device of the present application, the multi-layer fiber cloth is conveyed through the feeding mechanism 1, the heating mechanism 2, the resin soaking mechanism 3, the glue amount control mechanism 4, and the winding mechanism 5, which can improve the automation degree of the multi-layer cloth manufacturing process and improve the work efficiency. In addition, the movable cloth winding shaft 11 can improve the controllability and standardization of the staggered layer width between the layers of the multi-layer cloth, and the glue scraping roller 41 can improve the controllability and standardization of the amount of resin on the multi-layer cloth.

[0051] Further, with reference to Figure 2 and Figure 3 , and in combination with Figure 1 , the feeding mechanism 1 further comprises at least one first housing 12, and the plurality of movable cloth winding shafts 11 are connected with one first housing 12, or each movable cloth winding shaft 11 is connected with a plurality of first housings 12; the movable cloth winding shaft 11 comprises: an adjusting slide rail 111 extending along the second direction D2; a moving part 112 slidably connected with the adjusting slide rail 111 along the second direction D2; a feeding driving assembly 113 connected with the adjusting slide rail 111 and driving the moving part 112 to move along the second direction D2 relative to the adjusting slide rail 111; a first gas spring shaft 114 extending along the second direction D2 and connected with the moving part 112; the first gas spring shaft 114 further comprises a limiting baffle 114b and a first gas spring shaft body 114a, and the limiting baffle 114b is located on the side of the first gas spring shaft body 114a close to the moving part 112.

[0052] The first shell 12 of the winding mechanism 1 is used to protect the movable cloth roll shaft 11. One movable cloth roll shaft 11 can be protected by one first shell 12, that is, each movable cloth roll shaft 11 is connected with a plurality of first shells 12 respectively, or a plurality of movable cloth roll shafts 11 can be protected by one first shell 12, that is, a plurality of movable cloth roll shafts 11 are connected with one first shell 12. In the embodiment of the application, the first shell 12 is connected with the movable cloth roll shaft 11 one by one as an example for description.

[0053] The fiber cloth is wound on the first inflatable shaft 114, which includes a limiting baffle 114b and a first inflatable shaft body 114a. The first inflatable shaft body 114a is inflated to make the key bar extend to the inner wall of the fiber cloth roll to fix the fiber cloth roll. When the fiber cloth roll is installed, the fiber cloth roll is sleeved on the first inflatable shaft body 114a, and one end is abutted against the limiting baffle 114b. Then the key bar is inflated to extend, and the fiber cloth roll is fixed along the axial and circumferential directions of the first inflatable shaft body 114a.

[0054] The adjusting slide rail 111 extends along the second direction D2, the winding drive assembly 113 drives the moving part 112 to move along the second direction D2 relative to the adjusting slide rail 111, the first inflatable shaft 114 is connected with the moving part 112, and the winding drive assembly 113 can drive the first inflatable shaft 114 to move along the second direction D2 together with the fiber cloth roll, so as to adjust the position of the fiber cloth roll along the second direction D2. The positions of the plurality of movable cloth roll shafts 11 along the second direction D2 are independently adjusted, so that the positions of the plurality of fiber cloth rolls along the second direction D2 are independently adjusted, and the staggered layer width between the plurality of fiber cloths can be adjusted. Exemplarily, the winding drive assembly 113 can adopt the form of a numerical control motor, so as to accurately control the displacement of the moving part 112 and improve the control accuracy of the staggered layer width. In addition, the movable cloth roll shaft 11 further includes a rotating motor, which is used to control the rotation of the first inflatable shaft 114, that is, to control the winding and unwinding speed of the fiber cloth roll.

[0055] Further, continuing to refer to Figure 2 and Figure 3 , and combining Figure 1, the position difference of the moving part 112 of the plurality of movable cloth roll shafts 11 along the second direction D2 is greater than or equal to 5 mm and less than or equal to 50 mm, and considering that the position of the moving part 112 along the second direction D2 corresponds to the position of the fiber cloth along the second direction D2, the position difference between the fiber cloths of different layers is greater than or equal to 5 mm and less than or equal to 50 mm, that is, the staggered layer width is greater than or equal to 5 mm and less than or equal to 50 mm. When the multi-layer cloth made by the multi-cloth layer automatic staggered layer device of the embodiment of the application is used to make a wind turbine blade, the staggered layer width between the glass fiber cloths of each layer of the multi-layer cloth is 10-20 mm, and the staggered layer width of the multi-layer cloth that can be made by the multi-cloth layer automatic staggered layer device of the embodiment of the application is 5-50 mm, which is sufficient to meet the requirements of the wind turbine blade. It can be understood that the feed roll driving assembly 113 can adopt the form of a numerical control motor, which can accurately control the position of each movable cloth roll shaft 11 along the second direction D2, so that the adjustment accuracy of the staggered layer width is less than 2 mm.

[0056] Further, with reference to Figure 4 , and in combination with Figure 1 , the heating mechanism 2 comprises: a heating box 21, the heating box 21 being provided with an inlet 211 and an outlet 212; a heating temperature control assembly 22, at least part of the heating temperature control assembly 22 being arranged in the heating box 21; a plurality of guide rollers 23 extending along the second direction D2, at least part of the plurality of guide rollers 23 being arranged at the inlet 211, and / or at least part of the plurality of guide rollers 23 being arranged at the outlet 212.

[0057] The multi-layer fiber cloth enters the heating box 21 from the inlet 211, is heated in the heating box 21, and is then conveyed out of the outlet 212, thereby achieving local heating of the fiber cloth. The heating box 21 is provided with a heating temperature control assembly 22, which heats or stops heating according to the temperature in the heating box 21.

[0058] The guide rollers 23 are used to control the conveying direction of the fiber cloth in the heating box 21. The guide rollers 23 are arranged at the inlet 211 and / or the outlet 212 of the heating box 21 to adjust the conveying direction of the fiber cloth. When the guide rollers are arranged at the inlet 211 of the heating box 21, the guide rollers 23 can make the fiber cloth enter the heating box 21 in a proper direction, for example, making the fiber cloth enter the heating box 21 in a direction close to being perpendicular to the wall surface on which the inlet 211 is located, so as to reduce the risk of the fiber cloth being affected by the outer wall of the heating box 21. When the guide rollers are arranged at the outlet 212 of the heating box 21, the guide rollers 23 can make the fiber cloth exit the heating box 21 in a proper direction, for example, making the fiber cloth exit the heating box 21 in a direction close to being perpendicular to the wall surface on which the outlet 212 is located, so as to reduce the risk of the fiber cloth being affected by the outer wall of the heating box 21. It can be understood that the heating box 21 can also be provided with guide rollers 23 inside to adjust the heating time of the fiber cloth in the heating box 21 and improve the heating effect of the fiber cloth.

[0059] It should be noted that the guide roller 23 can be provided one-to-one with the movable cloth reel 11, that is, one guide roller corresponds to one layer of fiber cloth; or the guide roller 23 can be provided corresponding to a plurality of movable cloth reels 11, that is, one guide roller corresponds to a plurality of layers of fiber cloth.

[0060] Further, referring to Figure 4 , and combining Figure 1 , the difference between the holding temperature in the heating box 21 and the preset temperature is less than or equal to 3°C, the preset temperature is greater than or equal to 20°C and less than or equal to 60°C, that is, the temperature of the heating box 21 is 20-60°C, and the maximum error between the temperature of the heating box 21 and the preset temperature is 3°C. The fiber cloth after heating and holding is more easily attached to the numerical value.

[0061] Further, referring to Figure 5 , and combining Figure 1 , the multi-cloth layer automatic staggered layer device further comprises: a cloth layer relaxation mechanism 6, which is provided downstream of the heating mechanism 2 and upstream of the resin infiltration mechanism 3; the cloth layer relaxation mechanism 6 comprises at least one relaxation roller 61, which extends along the second direction D2 and is movably arranged along the first direction D1.

[0062] The cloth layer relaxation mechanism 6 is used to adjust the tension of the fiber cloth in transmission. Considering that the resin on the fiber cloth after resin infiltration has a certain viscosity, the cloth layer relaxation mechanism 6 is provided downstream of the heating mechanism 2 and upstream of the resin infiltration mechanism 3. The relaxation roller 61 extends along the second direction D2 and is movably arranged along the first direction D1. Moving the relaxation roller along the first direction D1 can change the total stroke of the fiber cloth transmission, and under the condition that the feeding speed of the feeding mechanism 1 is unchanged, the tension of the fiber cloth can be adjusted.

[0063] Further, referring to Figure 6 , and combining Figure 1 , the resin infiltration mechanism 3 comprises: a resin pool 32 for containing liquid resin, and the infiltration roller 31 can extend into the resin pool 32 along the first direction D1.

[0064] The resin pool 32 contains liquid resin, and the heated fiber cloth will pass around the infiltration roller 31, so when the infiltration roller 31 extends into the resin pool 32, the heated fiber cloth will also be immersed in the liquid resin of the resin pool 32. At this time, the liquid resin will be excessively and uniformly attached to the heated fiber cloth. A plurality of infiltration rollers 31 can be arranged along the first direction D1, and a gap is left between adjacent infiltration rollers 31, so that the resin attached to the fiber cloth corresponding to a certain infiltration roller 31 is almost not affected by other infiltration rollers 31.

Exemplarily, the glue scraping drive assembly 42 can be provided with at least two, each of which can drive one glue scraping roller 41 to move; the glue scraping drive assembly 42 can also be provided with one, which drives two glue scraping rollers 41 at the same time, or fixes one glue scraping roller 41, and the glue scraping drive assembly 42 drives the other glue scraping roller 41, for example, the glue scraping drive assembly 42. For example, the glue scraping drive assembly 42 can be in the form of a telescopic cylinder, or in the form of a sliding rail and a sliding block.

[0066] Further, referring to Figure 7 , and combining Figure 1 , the number of the glue scraping rollers 41 is two, and corresponds to the plurality of the impregnation rollers 31, that is, when each layer of the fiber cloth is impregnated with the resin and excessively adheres to the resin, the plurality of layers of the fiber cloth adhering to the resin passes through the gap between the two glue scraping rollers 41 at the same time, and the excess resin is scraped off, and at the same time, the plurality of layers of the fiber cloth are adhered together to form the plurality of layers of cloth with an appropriate amount of resin. Exemplarily, the weight of the resin on the plurality of layers of cloth can account for 40%-50% of the total weight.

In order to facilitate the subsequent use of the plurality of layers of cloth, exemplarily, the plurality of layers of cloth can be used to manufacture blades of wind power generators.

[0069] In summary, the application provides a multi-layer automatic staggered layer device. The multi-layer automatic staggered layer device comprises a feeding mechanism, a heating mechanism, a resin immersion mechanism, a glue amount control mechanism and a winding mechanism. The feeding mechanism can release multiple layers of fiber cloth respectively, and by moving the movable cloth roll shaft in the second direction, the multiple layers of fiber cloth can form a more accurate staggered layer of multiple layers of fiber cloth. The multiple layers of fiber cloth will enter the heating mechanism for heating. The immersion roller of the resin immersion mechanism immerses the heated multiple layers of fiber cloth in the resin, so that each layer of fiber cloth can be fully immersed in the resin. The multiple layers of fiber cloth pass through the gap between the glue scraping rollers of the glue amount control mechanism, and the excess resin is scraped off. By allowing at least two glue scraping rollers to approach or move away, the amount of resin on the multiple layers of cloth is adjusted. The winding mechanism can wind the scraped multiple layers of cloth, for subsequent use. The multi-layer automatic staggered layer device of the application embodiment can realize multi-layer cloth feeding, multi-layer automatic staggered layer, multi-layer heating, multi-layer automatic cloth immersion and multi-layer automatic winding, thereby improving the automation, controllability and standardization of the cloth immersion operation.
