[0039] Wind turbine blades are one of the core components of wind turbines. Their main function is to convert wind energy into mechanical energy, and then drive the generator to generate electricity. As the size of wind turbine blades increases, the role of the web in maintaining the overall stability of the wind turbine blades becomes increasingly important.

[0040] The web plays a key role in supporting and transferring loads in wind turbine blades. The accuracy of its installation position and posture directly affects the overall performance of the wind turbine blade. Therefore, in related technologies, certain auxiliary tooling is usually used to install the web to improve the web's correct position and angle during assembly.

[0041] However, the webs usually have complex shapes and sizes, and are easily deformed due to uneven force during assembly. Existing auxiliary tooling is difficult to adapt to the shapes and sizes of webs of different models, causing certain inconveniences during assembly.

[0042] In view of this, first of all, please refer to Figure 1 and Figure 2 The embodiment of the present application provides a wind turbine blade assembly tool for assembling a web, wherein the web includes a first plate body and a second plate body which are separately arranged. The wind turbine blade assembly tool includes a base 10, a limit assembly 20 and a support assembly 30. The limit assembly 20 is connected to the base 10 and is protruded relative to the base 10 along a first direction X. The limit assembly 20 includes a first limit member 21 and a second limit member 22 which are arranged at intervals along a second direction Y, and the second direction Y intersects with the first direction X. The support assembly 30 is connected to the first limit member 21 and the second limit member 22. The first limit member 21, the support assembly 30 and the second limit member 22 enclose a receiving cavity Q1 for accommodating the web. Among them, the support assembly 30 includes a connecting portion for connecting the limit assembly 20 and a supporting portion for supporting the web in the first direction X. The connecting portion is connected to the limit assembly 20 in an adjustable position along the first direction X, and the spacing between the supporting portion and the connecting portion in the first direction X is adjustable.

[0043] The wind turbine blade assembly tool provided in the embodiment of the present application is used to assemble the web in the wind turbine blade. The web is an important load transfer component of the wind turbine blade, and is mainly used in the main beam structure of the wind turbine blade to support the main beam. In the actual process, the web usually includes a first plate body and a second plate body that are separately arranged. In the assembly process of the wind turbine blade, the first plate body and the second plate body are bonded and assembled, and then the web is connected to the main beam of the wind turbine blade. In the actual assembly process, since the web has a certain length, a single wind turbine blade assembly tool only supports and limits one position in the length direction of the web. Therefore, for the assembly of the web, multiple wind turbine blades need to be spaced and distributed along the length direction of the web to form multiple positions of support for the web to ensure the support effect of the web, thereby facilitating the assembly of the web.

[0044] Specifically, the wind turbine blade assembly tooling includes a base 10, a limit assembly 20 and a support assembly 30. The base 10 is used to connect with other structures. The position where the base 10 is fixed is the corresponding position where the wind turbine blade assembly tooling is placed. For example, the base 10 and other structures can be connected by bolts and nuts. The support assembly 30 is used to support the web to fix the web at a certain height and form a gap between the web and the ground to facilitate the operation of technicians. The limit assembly 20 is used to limit the web located on the support assembly 30 to a certain extent to ensure the position stability of the web on the support assembly 30.

[0045] The limiting assembly 20 is connected to the base 10 and is protruded relative to the base 10 in the first direction X. The first direction X can be a vertical direction, that is, a height direction when assembling the web. The limiting assembly 20 includes a first limiting member 21 and a second limiting member 22 spaced apart along a second direction Y. The second direction Y can be any direction in the horizontal plane. When the web is supported by the supporting assembly 30, the web is located between the first limiting member 21 and the second limiting member 22. The first limiting member 21 is located on the side of the web away from the second limiting member 22 along the second direction Y, so as to form a support limit for the web on the side of the web away from the second limiting member 22 along the second direction Y, thereby ensuring the relative position relationship between the web and the second limiting member 22 and the supporting assembly 30. The second limiting member 22 is the same, and will not be described here.

[0046] In actual application, the support assembly 30 is located at the bottom along the first direction X, that is, the vertical direction, relative to the first stopper 21 and the second stopper 22, and the first stopper 21 and the second stopper 22 protrude from the support assembly 30 along the first direction X. The support assembly 30 extends along the second direction Y, and the two ends of the support assembly 30 along the second direction Y are respectively connected to the first stopper 21 and the second stopper 22. The support assembly 30 is spaced apart from the base 10 in the first direction X, and the web contacts the support assembly 30 along the bottom of the first direction X, and contacts the first stopper 21 on one side of the web along the second direction Y, and contacts the second stopper 22 on the other side of the web along the second direction Y. The first stopper 21, the support assembly 30 and the second stopper 22 enclose a receiving cavity Q1, and the web is located inside the receiving cavity Q1. The first limiting member 21, the supporting assembly 30 and the second limiting member 22 form contact positioning for the web in different directions, and restrict the web within the accommodating cavity Q1, so as to improve the positioning effect of the wind turbine blade assembly tooling on the web.

[0047] Furthermore, in order to improve the applicability of the wind turbine blade assembly tooling, enable the wind turbine blade assembly tooling to be applicable to different types of webs, and improve the assembly efficiency of technicians when assembling different types of webs, the support assembly 30 in the wind turbine blade assembly tooling provided in the embodiment of the present application includes a connecting portion and a supporting portion in the first direction X, the connecting portion is used to connect with the first limiting member 21 and the second limiting member 22, and the supporting portion is used to support the web.

[0048] Typically, the support assembly 30 includes certain dimensions in the first direction X, the connecting portion in the support assembly 30 determines the bottom height of the support assembly 30, the supporting portion in the support assembly 30 determines the top height of the support assembly 30, the connecting portion is connected to the first limit member 21 and the second limit member 22, and the supporting portion supports the belly plate.

[0049] A plurality of first connection positions are arranged at intervals along the first direction X on the first stopper 21, and a plurality of second connection positions are arranged at intervals along the first direction X on the second stopper 22, and the first connection positions correspond to the second connection positions one by one in the first direction X. The connecting portion can be selectively connected to a certain first connection position and a certain second connection position. When the connecting portion is connected to different first connection positions and second connection positions, the distance between the connecting portion and the base 10 in the first direction X is different, the distance between the support portion and the end of the first stopper 21 away from the base 10 in the first direction X is different, and the distance between the support portion and the end of the second stopper 22 away from the base 10 in the first direction X is different.

[0050] When the web is located in the wind turbine blade assembly tooling provided in the embodiment of the present application, webs of different models have different sizes in the first direction X. When the size of the web in the first direction X is larger than the spacing between the support portion and the end of the first limiting member 21 away from the base 10 in the first direction X, the web protrudes from the first limiting member 21 in the first direction X, and the first limiting member 21 can hardly ensure the limiting effect of the web; when the size of the web in the first direction X is smaller than the spacing between the support portion and the end of the first limiting member 21 away from the base 10 in the first direction X, the first limiting member 21 protrudes from the web in the first direction X, causing a certain degree of inconvenience to the assembly of the web.

[0051] Therefore, by connecting the position-limiting assembly 20 whose connection part is adjustable in the first direction X, the distance between the connection part and the base 10 in the first direction X can be adjusted by changing the connection position of the connection part on the limiting assembly 20, thereby adjusting the distance between the support part and the end of the first limiting member 21 away from the base 10 in the first direction X in the first direction X. When assembling webs of different models, the technician can change the connection position of the connection part on the limiting assembly 20, so that the distance between the web of the corresponding model and the end of the support part and the first limiting member 21 away from the base 10 in the first direction X in the first direction X is adapted, which is convenient for the technician to operate while ensuring the positioning effect of the web.

[0052] At the same time, the spacing between the support portion and the connection portion in the first direction X is set to be adjustable. When the connection portion is connected to the first stopper 21 and the second stopper 22, the spacing between the support portion and the end of the first stopper 21 away from the base 10 in the first direction X in the first direction X is preliminarily determined. In the actual assembly process, for some models of webs with small size differences, the spacing between the support portion and the end of the first stopper 21 away from the base 10 in the first direction X in the first direction X can be adjusted by adjusting the spacing between the support portion and the connection portion in the first direction X, thereby adjusting the spacing between the support portion and the end of the first stopper 21 away from the base 10 in the first direction X in the first direction X more simply, so that the spacing between the support portion and the end of the first stopper 21 away from the base 10 in the first direction X in the first direction X in the first direction X is more quickly made to correspond to the web size of the corresponding model, thereby improving the assembly efficiency of the technicians.

[0053] Optionally, the position adjustment of the support portion on the first limiter 21 and the second limiter 22 along the first direction X is set as an intermittent adjustment mode, and the connection position of the support portion on the first limiter 21 and the second limiter 22 is a fixed point connection to ensure the connection reliability between the support portion and the first limiter 21 and the second limiter 22. Exemplarily, a plurality of threaded holes are arranged at intervals on the first limiter 21 and the second limiter 22, and the support portion is connected to the first limiter 21 and the second limiter 22 by bolt connection. The adjustment between the support portion and the connection portion along the first direction X is a continuous adjustment, and the spacing between the support portion and the connection portion can be any value in a certain interval to improve the applicability of the wind turbine blade assembly tooling provided in the embodiment of the present application. Exemplarily, the support portion and the connection portion can also be connected by bolts to continuously adjust the spacing between the support portion and the connection portion.

[0054] In summary, in the wind turbine blade assembly tool provided in the embodiment of the present application, it is used to assemble the web in the wind turbine blade. The wind turbine blade assembly tool includes a base 10, a limit assembly 20 and a support assembly 30. The limit assembly 20 is connected to the base 10 and is protruded relative to the base 10 in a first direction X. The first direction X can be a vertical direction, that is, the height direction when assembling the web. The limit assembly 20 includes a first limit member 21 and a second limit member 22 arranged at intervals along a second direction Y. The second direction Y can be any direction in the horizontal plane. The support assembly 30 is located at the bottom along the first direction X, that is, the vertical direction, relative to the first limit member 21 and the second limit member 22. The first limit member 21 and the second limit member 22 protrude from the support assembly 30 along the first direction X. The support assembly 30 extends along the second direction Y, and the two ends of the support assembly 30 along the second direction Y are connected to the first stopper 21 and the second stopper 22 respectively. The support assembly 30 is spaced apart from the base 10 in the first direction X, and the bottom of the web along the first direction X contacts the support assembly 30, and one side of the web along the second direction Y contacts the first stopper 21, and the other side of the web along the second direction Y contacts the second stopper 22, so as to improve the positioning effect of the wind turbine blade assembly tool on the web. Further, the support assembly 30 includes a connecting portion for connecting the stopper assembly 20 and a supporting portion for supporting the web in the first direction X, and the connecting portion is connected to the stopper assembly 20 in an adjustable position in the first direction X, and the distance between the connecting portion and the base 10 in the first direction X can be adjusted by changing the connection position of the connecting portion on the stopper assembly 20, thereby adjusting the distance between the supporting portion and the end of the first stopper 21 in the first direction X away from the base 10 in the first direction X. When assembling webs of different models, the technician can change the connection position of the connection part on the limiting assembly 20, so that the web of the corresponding model is matched with the support part and the first limiting member 21 at the end away from the base 10 in the first direction X in the first direction X, which is convenient for the technician to operate while ensuring the positioning effect of the web. At the same time, the spacing between the support part and the connection part in the first direction X is adjustable, so that by adjusting the spacing between the support part and the connection part in the first direction X, the spacing between the support part and the end away from the base 10 in the first direction X of the first limiting member 21 is adjusted, thereby improving the applicability of the wind turbine blade assembly tool provided in the embodiment of the present application.

[0055] In some embodiments, the support assembly 30 includes a connecting member 31 and a first supporting member 32 and a second supporting member 33 connected to the connecting member 31. The two ends of the connecting member 31 along the second direction Y are respectively connected to the first stopper 21 and the second stopper 22. The first supporting member 32 and the second supporting member 33 are spaced apart along the second direction Y. The first supporting member 32 is configured to support the first plate body, and the second supporting member 33 is configured to support the second plate body.

[0056] In actual applications, the web usually includes a first plate body and a second body that are separately arranged. In order to provide good support for the web, the support assembly 30 includes a first support member 32 and a second support member 33. The first support portion 321 is used to support the first plate body, and the second support member 33 is used to support the second plate body. The first support member 32 and the second support member 33 are simultaneously connected to the connecting member 31, and the connecting member 31 connects the first support member 32 and the second support member 33 to the limiting assembly 20.

[0057] The bottom of the first plate is in contact with the first support member 32, and the side of the first plate facing away from the second plate is in contact with the first stopper 21. The bottom of the second plate is in contact with the second support member 33, and the side of the second plate facing away from the first plate is in contact with the second stopper 22. Under the action of the first stopper 21 and the second stopper 22, the first plate and the second plate are connected to each other on one side, so that technicians can assemble the first plate and the second plate.

[0058] In some embodiments, the connecting member 31 includes a first connecting portion 311 and a second connecting portion 312 that are bent and connected, and a side of the first connecting portion 311 that is away from the second connecting portion 312 is in contact with and connected to the first stopper 21 and the second stopper 22. The first supporting member 32 and the second supporting member 33 are connected to the second connecting portion 312. The first supporting member 32 and the second supporting member 33 are located on one side of the stopper assembly 20 along the third direction Z, and the third direction Z, the second direction Y, and the first direction X intersect each other.

[0059] The connecting member 31 connects the first supporting member 32 and the second supporting member 33 to the limiting assembly 20, and the connecting member 31 also needs to be connected to the limiting assembly 20 in an adjustable position. In order to facilitate the adjustable connection of the connecting member 31 to the limiting assembly 20 while ensuring the supporting effect of the first supporting member 32 and the second supporting member 33 on the web, a specific arrangement is made for the structure of the connecting member 31.

[0060] The connecting member 31 includes a first connecting portion 311 and a second connecting portion 312 which are bent and connected. The side of the first connecting portion 311 which is away from the second connecting portion 312 is in contact with and connected to the first stopper 21 and the second stopper 22. In other words, the first connecting portion 311 in the connecting member 31 is used to connect with the first stopper 21 and the second stopper 22. The second connecting portion 312 is located at the side of the first connecting portion 311 which is away from the first stopper 21 and the second stopper 22, and is used to connect with the first support member 32 and the second support member 33.

[0061] At the same time, in order to facilitate the technicians to adjust the connection position of the connecting piece 31 and the distance between the supporting part and the connecting part, the supporting assembly 30 is arranged on one side of the limiting assembly 20 along the third direction Z, that is, the supporting assembly 30 and the limiting assembly 20 are staggered in the third direction Z to form a larger space for the technicians' operation.

[0062] The first connection portion 311 is connected to one side of the first stopper 21 and the second stopper 22 along the third direction Z. The first connection portion 311 is arranged along a vertical plane so as to have a large overlap area with the first stopper 21 and the second stopper 22, which facilitates the connection between the first connection portion 311 and the first stopper 21 and the second stopper 22. The second connection portion 312 is connected to one side of the first connection portion 311 away from the first stopper 21 and the second stopper 22 along the third direction Z. The second connection portion 312 is arranged along a horizontal plane so as to be connected to the first support member 32 and the second support member 33, so as to ensure the supporting effect on the web.

[0063] In some embodiments, the second connection portion 312 is provided with a connection hole K1 along the first direction X. The size of the connection hole K1 along the second direction Y is greater than its size along the third direction Z. The third direction Z, the second direction Y and the first direction X intersect each other. The first support member 32 and the second support member 33 are both slidably connected along the second direction Y inside the connection hole K1.

[0064] In actual applications, the spacing between the first plate body and the second plate body is different. Correspondingly, in order to ensure the supporting effect of the first support member 32 on the first plate body and the second support member 33 on the second plate body, the spacing between the first support member 32 and the second support member 33 along the second direction Y is set to be adjustable.

[0065] Specifically, a connection hole K1 is provided on the second connection portion 312 along the first direction X, and the size of the connection hole K1 along the second direction Y is greater than the size along the third direction Z. The first support member 32 and the second support member 33 are both connected to the connection hole K1, and can slide in the connection hole K1 along the second direction Y to adjust the relative positions of the first support member 32 and the second support member 33 relative to the second connection portion 312, so as to form targeted support for the first plate body and the second plate body.

[0066] In some embodiments, the first support member 32 includes a first support portion 321, a second support portion 322 and a third support portion 323 connected to both ends of the first support portion 321 along the second direction Y, and an end of the second support portion 322 away from the first support portion 321 and an end of the third connection portion away from the first support portion 321 are both connected to the connection member 31. A surface of a side of the first support portion 321 away from the second support portion 322 is located on a side of the connection member 31 away from the base 10, and the second support portion 322 and the third support portion 323 are slidably connected to the connection member 31 along the first direction X to adjust the distance between the first support portion 321 and the connection member 31.

[0067] The first support portion 321 is arranged in the horizontal direction, and the first support portion 321 is used to support the first plate body. The second support portion 322 and the third support portion 323 are arranged in the vertical direction, and the first support portion 321 is connected to the second connection portion 312. The second support portion 322 and the third support portion 323 are respectively connected to the two ends of the first support portion 321 along the second direction Y, so as to form a relatively balanced support for the first support portion 321, so as to ensure the supporting effect for the first plate body.

[0068] Further, the second support part 322 and the third support part 323 are connected to the connection hole K1 by sliding along the first direction X. When the second support part 322 and the third support part 323 slide in the direction away from the base 10, the first support part 321 is driven away from the second connection part 312, and the distance between the first support part 321 and the second connection part 312 becomes larger; when the second support part 322 and the third support part 323 slide in the direction close to the base 10, the first support part 321 is driven close to the second connection part 312, and the distance between the first support part 321 and the second connection part 312 becomes smaller. It can be understood that the surface of the side of the first support part 321 away from the second support part 322 is always on the side of the connecting member 31 away from the base 10, and the first support part 321 is protruding from the connecting member 31 in the first direction X, reducing the probability of the first plate body contacting with the connecting member 31, so as to ensure good support for the first plate body.

[0069] The second support portion 322 and the third support portion 323 can both be configured as a screw structure, so that the second support portion 322 can slide along the connection hole K1 along the second direction Y and along the first direction X. Taking the second support portion 322 as an example, the second support portion 322 is penetrated through the connection hole K1, and the portions of the second support portion 322 located on both sides of the connection hole K1 along the first direction X are connected to a nut. When the second support portion 322 needs to slide relative to the connection hole K1, the two nuts are loosened away from each other, and the second support portion 322 slides inside the connection hole K1; when the second support portion 322 needs to be fixed relative to the connection hole K1, the two nuts are tightened close to each other, and the second support portion 322 is fixed inside the connection hole K1. The same principle applies to the third support portion 323, which will not be repeated here.

[0070] In some embodiments, the second support portion 322 is rotatably connected to the first support portion 321 in the third direction Z, and the third support portion 323 is rotatably connected to the first support portion 321 in the third direction Z, and the third direction Z, the second direction Y, and the third direction Z intersect each other. The second support portion 322 and the third support portion 323 are both slidably connected to the connecting member 31 along the first direction X to adjust the inclination angle of the first support portion 321 relative to the connecting member 31.

[0071] In order to achieve a good fit between the first support portion 321 and the web, based on the certain inclination angle of the web flange, the first support portion 321 is configured so that the heights of both ends along the second direction Y are independently adjustable to adjust the inclination angle of the first support portion 321 relative to the second connection portion 312.

[0072] Generally, the first support portion 321 is arranged relatively parallel to the second connection portion 312. When the second support portion 322 slides away from the base 10 along the first direction X, the connection position between the second support portion 322 and the first support portion 321 rotates relatively, and the end of the first support portion 321 connected to the second support portion 322 moves away from the second connection portion 312, and the first support portion 321 forms a certain tilt angle. When the third support portion 323 slides relatively along the first direction X, the same principle applies, which will not be repeated here.

[0073] In some embodiments, the first support portion 321 is provided with a first protrusion and a second protrusion protruding from a side surface of the first support portion 321 away from the connecting member 31, and the first protrusion and the second protrusion are respectively arranged at two ends of the first support portion 321 along the second direction Y, and the first protrusion, the first support portion 321 and the second protrusion are enclosed to form a first support groove C1.

[0074] When the first support portion 321 has a certain inclination angle relative to the second connection portion 312 , in order to reduce the probability of the first plate body sliding relative to the first support portion 321 , a first convex portion and a second convex portion are provided on the first support portion 321 to limit the first plate body.

[0075] When the first plate body is supported by the first support portion 321, the first plate body is located along the second direction Y between the first convex portion, the first support portion 321 and the first support groove C1 formed by the second convex portion, and the end of the first plate body in contact with the first support portion 321 is arranged in contact with the first convex portion and the second convex portion. When the first support portion 321 tilts, the first convex portion and the second convex portion can limit the first plate body, thereby reducing the probability of the first plate body sliding relative to the first support portion 321 and improving the position stability of the first plate body on the first support portion 321.

[0076] In some embodiments, the second support member 33 has a similar structure to the first support member 32. The second support member 33 includes a fourth support portion 331, a fifth support portion 332 and a sixth support portion 333 connecting the two ends of the fourth support portion 331 along the second direction Y. The end of the fifth support portion 332 away from the fourth support portion 331 and the end of the sixth support portion 333 away from the fourth support portion 331 are both connected to the connecting member 31. A surface of the side of the fourth support portion 331 away from the fifth support portion 332 is located on the side of the connecting member 31 away from the base 10. The fifth support portion 332 and the sixth support portion 333 are slidably connected along the first direction X to adjust the distance between the fourth support portion 331 and the connecting member 31. The beneficial effects produced by the above structure are similar to those produced by the structure of the first support member 32, and are not repeated here.

[0077] The fifth support portion 332 is connected to the fourth support portion 331 for rotation around the third direction Z, and the sixth support portion 333 is connected to the fourth support portion 331 for rotation around the third direction Z. The fifth support portion 332 and the fourth support portion 331 are both connected to the connecting member 31 for sliding along the first direction X to adjust the inclination angle of the fourth support portion 331 relative to the connecting member 31. The beneficial effects produced by the above structure are similar to those produced by the structure in the first support member 32, and are not described in detail here.

[0078] The fourth support portion 331 is provided with a third convex portion and a fourth convex portion protruding from the surface of the fourth support portion 331 on the side away from the connecting member 31, and the third convex portion and the fourth convex portion are respectively provided at both ends of the first support portion 321 along the second direction Y, and the third convex portion, the fourth support portion 331 and the fourth convex portion enclose a second support groove C2. The beneficial effects produced by the above structure are similar to those produced by the structure in the first support member 32, and are not repeated here.

[0079] In some embodiments, the base 10 is provided with an avoidance hole K2 along the first direction X, and the projection of the first support member 32 in the first direction X and the projection of the second support member 33 in the first direction X are both located inside the avoidance hole K2.

[0080] When the support assembly 30 is adjusted relative to the limit assembly 20 along the first direction X, the support assembly 30 may be at the bottom of the limit assembly 20. In order to reduce the probability of interference between the support assembly 30 and the base 10, an avoidance hole K2 is provided on the base 10 to avoid the support assembly 30. In the actual adjustment process, the connecting member 31 is connected to the limit assembly 20, and the first support member 32 and the second support member 33 are adjusted relative to the connecting member 31. In order to reduce the probability of interference between the first support member 32, the second support member 33 and the base 10, the projection of the first support member 32 in the first direction X and the projection of the second support member 33 in the first direction X are both arranged inside the avoidance hole K2, and the avoidance hole K2 forms an avoidance for the first support member 32 and the second support member 33.

[0081] In some embodiments, the first stopper 21 includes a first fixing portion 211 fixedly connected to the base 10 and a first adjusting portion 212 slidably connected to the first fixing portion 211 along the second direction Y, and the second stopper 22 includes a second fixing portion 221 fixedly connected to the base 10 and a second adjusting portion 222 slidably connected to the second fixing portion 221 along the second direction Y. The first adjusting portion 212 is located on a side of the first fixing portion 211 facing the second stopper 22, and the second adjusting portion 222 is located on a side of the second fixing portion 221 facing the first stopper 21.

[0082] For different types of webs, there are differences in the sizes of the first plate body and the second plate body along the second direction Y. In order to ensure that the first limiting member 21 and the second limiting member 22 have a good limiting effect on different webs, the distance between the first limiting member 21 and the second limiting member 22 is set to be adjustable.

[0083] The first stopper 21 includes a first fixing portion 211 fixedly connected to the base 10, the second stopper 22 includes a second fixing portion 221 fixedly connected to the base 10, and the connecting member 31 is connected to the first fixing portion 211 and the second fixing portion 221. The first fixing portion 211 and the second fixing portion 221 provide a stable frame structure for the overall structure.

[0084] The first limiting member 21 also includes a first adjusting portion 212 slidably connected to the first fixing portion 211, and the second limiting member 22 also includes a second adjusting portion 222 slidably connected to the second fixing portion 221, and the first adjusting portion 212 and the second adjusting portion 222 are contact-limited relative to the web. When the first adjusting portion 212 and the second adjusting portion 222 slide toward each other, the distance between the first adjusting portion 212 and the second adjusting portion 222 decreases, which is suitable for positioning a web with a smaller size; when the first adjusting portion 212 and the second adjusting portion 222 slide away from each other, the distance between the first adjusting portion 212 and the second adjusting portion 222 increases, which is suitable for positioning a web with a larger size.

[0085] In some embodiments, the first limit member 21 and the second limit member 22 form an opening structure K3 on the side away from the support assembly 30, a first guide structure 213 is provided at the end of the first adjustment portion 212 away from the base 10, and a second guide structure 223 is provided at the end of the second adjustment portion 222 away from the base 10, and a spacing dimension along the second direction Y between the first guide structure 213 and the second guide structure 223 at one end toward the base 10 is smaller than a spacing dimension along the second direction Y between the first guide structure 213 and the second guide structure 223 at one end away from the base 10.

[0086] Considering that the lifting structure is often used in the process of transferring the web, an opening structure K3 is formed on the side of the first stopper 21 and the second stopper 22 away from the support assembly 30, and the web enters the accommodating cavity Q1 through the opening structure K3, and is then supported by the support assembly 30 and limited by the stopper assembly 20. In order to reduce the damage to the surface of the web caused by the first stopper 21 and the second stopper 22, and facilitate the web to enter the accommodating cavity Q1 through the opening structure K3, a first guide structure 213 is provided at one end of the first adjustment portion 212 away from the base 10, and a second guide structure 223 is provided at one end of the second adjustment portion 222 away from the base 10, so as to increase the size of the opening structure K3 and facilitate the web to enter the accommodating cavity Q1.

[0087] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict.
