Description

Technical Field

[0001] This utility model relates to the field of winding machines, specifically to a winding assembly, and to a winding machine. Background Technology

[0002] In existing technologies, winding machines for tubular products (such as strip-reinforced RTP pipes) generally employ gantry winding machines, ground winding machines, or horizontal winding machines. These types of winding machines all require reels; the winding machine provides the winding power, the pipe or other product is wound onto the reel, and after winding, the pipe and reel are simultaneously lifted off the winding machine for storage and transportation. It can be seen that using these winding machines requires a large number of reels to be wound, and the reels occupy a significant amount of space, thus requiring substantial capital investment in both the reels and the space. Furthermore, it increases the cost of two-way transportation of the reels, and the reels are also prone to damage, further increasing costs. Utility Model Content

[0003] The purpose of this invention is to overcome the problem of increased costs associated with using reels in existing winding machines.

[0004] To achieve the above objectives, the present invention provides a winding assembly, comprising:

[0006] Multiple strip-shaped support plates extend along the axial direction of the central cylinder and are arranged around the central axis of the central cylinder on the outer periphery of the central cylinder to form a support structure for winding products;

[0007] The first stop rod is connected to the first axial end of the support plate and extends outward along the radial direction of the central cylinder;

[0008] The first axial end of the support plate is capable of radial movement to reduce the outer diameter of the first axial end of the support structure, and the first stop is capable of rotation relative to the support plate such that the radial dimension of the first stop is less than or equal to the radial dimension of the first axial end of the support structure, thereby allowing the product wrapped around the support structure to be removed from the first axial end of the support structure.

[0015] In some embodiments, the second axial end of the support plate is rotatably hinged to the second movable seat via a second hinge shaft extending in the tangential direction. The first movable seat is capable of radial movement to drive the first axial end of the support plate to rotate around the second hinge shaft, thereby adjusting the outer diameter of the first axial end of the support structure.

[0016] In some embodiments, the system further includes a second driving member disposed on the central cylinder for driving the second movable seat and a second linear guide rail for supporting the second movable seat.

[0017] In some embodiments, the second drive member includes a second motor and a second lead screw that is driven to the second motor and screwed to the second movable seat.

[0018] On the other hand, this solution also provides a winding machine, which includes a frame, a slewing bearing mounted on the frame, a main motor, and the winding assembly described in the above solution. The winding assembly is rotatably mounted on the slewing bearing about a central axis. The outer gear ring of the slewing bearing is engaged with a drive gear.

Detailed Implementation

[0028] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0029] refer to Figures 1-8 As shown, this solution provides a winding component, which includes:

[0030] Rotatable central cylinder 1;

[0031] Multiple strip-shaped support plates 3 extend along the axial direction of the central cylinder 1 and are arranged around the central axis of the central cylinder 1 on the outer periphery of the central cylinder 1 to form a support structure for winding products.

[0032] The first stop 2 is connected to the first axial end of the support plate 3 and extends outward along the radial direction of the central cylinder 1;

[0033] The first axial end of the support plate 3 can be moved radially to reduce the outer diameter of the first axial end of the support structure, and the first stop 2 can be rotated relative to the support plate 3 so that the radial dimension of the first stop 2 is less than or equal to the radial dimension of the first axial end of the support structure, thereby allowing the product wrapped around the support structure to be removed from the first axial end of the support structure.

[0034] Support plates 3 are arranged at intervals around the central cylinder 1 in a circumferential manner to form a support structure. Product 25 can be wound around the support structure. The outer surface of the support plates 3 can serve as a support surface for product 25. (Refer to...) Figure 2 As shown. Products that can be wound around a support structure can be elongated shapes, such as pipes, wires, etc., such as RTP pipes (reinforced thermoplastic pipes).

[0035] The first stop 2 is located at the first axial end of the support plate 3. During product winding, the first stop 2 acts as a stop and limit mechanism, preventing the product 25 from falling off the first axial end of the support structure. (Refer to...) Figure 2 As shown. In addition, a second stop 4 is provided at the second axial end of the support plate 3 or the second axial end of the central cylinder 1, which also serves to limit the winding of the product.

[0036] The first axial end of the support plate 3 can move radially, including radially inward and radially outward. When the product winding is complete, the first axial end of the support plate 3 can move radially inward, which reduces the overall outer diameter of the first axial end of the support structure, so the product is no longer tightly attached to the support structure. Furthermore, the first stop 2 can rotate relative to the support plate 3 so that the radial dimension of the first stop 2 is less than or equal to the radial dimension of the first axial end of the support structure. The radial dimension of the first stop 2 refers to the distance between its outermost radial portion and the central axis of the central cylinder 1. The radial dimension of the first axial end of the support structure refers to the distance between it and the central axis of the central cylinder 1 (i.e., its overall outer diameter). In other words, the first stop 2 does not protrude radially outward relative to the first axial end of the support structure. Therefore, the first stop 2 no longer restricts the axial movement of the product 25, allowing the product 25 to be removed from the support structure along the direction from the second axial end toward the first axial end. Therefore, it is no longer necessary to install a detachable winding reel for winding the product on the winding assembly.

[0037] After the product is removed from the winding assembly, the first axial end of the support plate 3 can be moved radially outward, so that the outer diameters of the two axial ends of the support structure are basically the same, and the first stop 2 can be rotated back to the position extending radially outward from the support plate 3.

[0038] Regarding the support plate 3, when its first axial end moves radially, the entire support plate 3 rotates around its second axial end, thereby making the support structure form a frustum-like structure where the outer diameter of the first axial end is smaller than the outer diameter of the second axial end.

[0039] This solution allows products to be directly wound onto the winding assembly and easily removed, simplifying the winding operation. It also eliminates the need for additional winding reels and provides space for them, saving on transportation costs. Therefore, it can significantly reduce costs.

[0040] In some embodiments, the winding assembly further includes a first movable seat 11 disposed on the central cylinder 1. The first movable seat 11 is hinged to the support plate 3 via a first hinge shaft 17 extending tangentially. The second axial end of the support plate 3 is rotatably hinged to the central cylinder 1 or the second movable seat 15 via a second hinge shaft 18 extending tangentially. The first movable seat 11 can move radially to drive the first axial end of the support plate 3 to rotate around the second hinge shaft 18, thereby adjusting the outer diameter of the first axial end of the support structure. Here, the tangential direction refers to the tangential direction at the location of the first hinge shaft 17 or the second hinge shaft 18 on the support structure. The second axial end of the support plate 3 can rotate around the second hinge shaft 18. When the first movable seat 11 moves radially, it can drive the first axial end of the support plate 3 to move radially, and the entire support plate 3 rotates around the second hinge shaft 18. Furthermore, the fact that the first axial end of the support plate 3 can rotate around the first hinge shaft 17 can prevent the support plate 3 and the first movable seat 11 from jamming when the first movable seat 11 moves. When the first axial end of the support plate 3 rotates around the second hinge shaft 18, the path of the first axial end of the support plate 3 is arc-shaped, while the movement of the first movable seat 11 is linear. Therefore, in order to avoid the first movable seat 11 from jamming with the support plate 3, there is a large gap between the through hole on the support plate 3 that accommodates the first hinge shaft 17 and the first hinge shaft 17, so as to satisfy the error between the movement paths of the first movable seat 11 and the support plate 3. For example, the cross-section of the through hole can be a long strip along the length direction of the support plate 3, and the width of the long strip through hole can be basically the same as the outer diameter of the first hinge shaft 17. The through hole can be formed on the mounting base described below.

[0041] In some embodiments, the winding assembly further includes a first driving member disposed on the central cylinder 1 for driving the first movable seat 11 to move radially, and a first linear guide rail 12 for supporting the first movable seat 11. (See reference) Figure 4 As shown, the first linear guide 12 extends generally radially and can guide the radial movement of the first movable seat 11. The first driving member can drive the first movable seat 11 to move. Of course, in other embodiments, the first movable seat 11 can also be manually driven to move radially.

[0042] In some embodiments, the first driving member includes a first motor 9 and a first lead screw 10, which is drively connected to the first motor 9 and screwed to the first movable seat 11. The first lead screw 10 extends radially, and the first motor 9 can drive the first lead screw 10 to rotate. The first movable seat 11, screwed to the first lead screw 10, moves radially under the action of the first lead screw 10. That is, the first lead screw 10 and the first movable seat 11 form a lead screw mechanism. In other embodiments, the first driving member can also be a hydraulic cylinder, pneumatic cylinder, or other structure, which can also drive the first movable seat 11 to move linearly.

[0043] Among them, reference Figure 4 As shown, a first mounting plate 22 is provided at the first axial end of the central cylinder 1, and the first motor 9 and the first linear guide rail 12 can be mounted on the first mounting plate 22.

[0044] In some embodiments, the first stop 2 is rotatably connected to the axial first end of the support plate 3 via a third hinge shaft 19 extending tangentially. Here, the tangential direction refers to the tangential direction of the location of the third hinge shaft 19 on the support structure. After rotating around the third hinge shaft 19, the first stop 2 can reach the direction extending in the same direction as the support plate 3, i.e., the generatrix direction of the frustum-shaped or cylindrical support structure, thereby releasing the limiting and stopping effect of the first stop 2 on the product on the support structure. The third hinge shaft 19 can be disposed on the central cylinder 1, or on other structures on the central cylinder 1.

[0045] In some embodiments, the winding assembly further includes a telescopic drive member 21 disposed radially inside the support plate 3, and a connecting rod 20 with its two ends respectively connected to the first stop rod 2 and the telescopic drive member 21. The telescopic drive member 21 is telescopic to drive the first stop rod 2 to rotate around the third hinge axis 19 via the connecting rod 20. One end of the telescopic drive member 21 is rotatably hinged to the radially inside of the support plate 3. One end of the connecting rod 20 is fixedly connected to the end of the first stop rod 2 that is hinged to the support plate 3, and the other end is hinged to the telescopic drive member 21. When the telescopic drive member 21 telescopically extends or retracts, it can drive the connecting rod 20 and the first stop rod 2 to rotate around the third hinge axis 19. The telescopic drive member 21 can be a cylinder, hydraulic cylinder, etc. Of course, in other embodiments, the first stop rod 2 can also be driven to rotate around the third hinge axis 19 by a motor, or it can be manually driven to rotate.

[0046] In some embodiments, the winding assembly further includes a second movable seat 15 radially movably disposed on the central cylinder 1. The second axial end of the support plate 3 is disposed on the second movable seat 15. The support plate 3 can be configured to move radially synchronously at its first and second axial ends to adjust the overall outer diameter of the support structure. The second movable seat 15 is located at the second axial end of the central cylinder 1, and the second axial end of the support plate 3 is disposed on the second movable seat 15. When the second movable seat 15 and the first movable seat 11 move radially inward or outward simultaneously, the support plate 3 moves radially inward or outward as a whole, which can change the overall outer diameter of the support structure. That is, by adjusting the radial position of the support plate 3 relative to the central cylinder 1, the overall outer diameter of the support structure can be adjusted to suit different product winding requirements.

[0047] In some embodiments, the second axial end of the support plate 3 is rotatably hinged to the second movable seat 15 via a second hinge shaft 18 extending tangentially. The first movable seat 11 is radially movable to drive the first axial end of the support plate 3 to rotate around the second hinge shaft 18, thereby adjusting the outer diameter of the first axial end of the support structure. The second movable seat 15 may be provided with the second hinge shaft 18 to be hinged to the second axial end of the support plate 3. When the first movable seat 11 moves radially, it drives the first axial end of the support plate 3 to move radially, that is, to rotate around the second hinge shaft 18.

[0048] Additionally, the winding assembly includes a second drive member disposed on the central cylinder 1 for driving the second movable seat 15 and a second linear guide rail 16 for supporting the second movable seat 15. The second linear guide rail 16 guides the second movable seat 15 to move radially, and the second drive member provides driving force for the movement of the second movable seat 15. Of course, in other embodiments, the second movable seat 15 can also be driven radially manually.

[0049] In some embodiments, the second driving element includes a second motor 13 and a second lead screw 14, which is drively connected to the second motor 13 and screwed to the second movable seat 15. The second lead screw 14 extends radially, and the second motor 13 can drive the second lead screw 14 to rotate. The second movable seat 15, screwed to the second lead screw 14, can move linearly along the second lead screw 14. That is, the second lead screw 14 and the second movable seat 15 form a lead screw mechanism, through which the second motor 13 can drive the second movable seat 15 to move radially. In other embodiments, the second driving element may also include a cylinder or a hydraulic cylinder, which can also drive the second movable seat 15 to move linearly.

[0050] Among them, reference Figure 4As shown, the second motor 13 and the second linear guide rail 16 can be mounted on the second mounting plate 23 at the second axial end of the central cylinder 1. In particular, the second stop 4 is mounted on the second mounting plate 23, and the second linear guide rail 16 can also be mounted on the second stop 4.

[0051] refer to Figure 7 and Figure 8 As shown, the first mounting plate 22 and the second mounting plate 23 on the central cylinder 1 can be connected by a tie rod 24 to ensure the stability of the overall structure.

[0052] Additionally, the support plate 3 may include a plate portion and a mounting base for supporting the plate portion. The radially outer surface of the plate portion is an arc surface. The plate portion is used to support the product. The mounting base may be hinged to the first hinge shaft 17, the second hinge shaft 18, and the third hinge shaft 19.

[0053] On the other hand, this solution provides a winding machine, which includes a frame 6, a slewing bearing 7 mounted on the frame 6, a motor 8, and the winding assembly described in the above solution. The winding assembly is rotatably mounted on the slewing bearing 7 along its central axis. The outer gear ring of the slewing bearing 7 is engaged with a drive gear. The motor 8 is connected to the drive gear to provide rotational power to the slewing bearing 7. The frame 6 serves as a supporting base. The fixed portion of the slewing bearing 7 is mounted on the frame 6, and the rotatable portion of the slewing bearing 7 is connected to the winding assembly, for example, to the central cylinder 1 of the winding assembly. In particular, it can be connected to a second mounting plate 23 at the axial second end of the central cylinder 1. The winding assembly can rotate relative to the frame 6. It can be driven manually or by other drive mechanisms. For example, a main motor 8 can be installed in the frame 6, and the rotatable part of the slewing bearing 7 is equipped with an external gear ring. The output end of the main motor 8 can be connected (e.g., through a reducer, transmission component, etc.) to a drive gear meshing with the external gear ring. The main motor 8 can drive the slewing bearing 7 and the winding assembly to rotate. The frame 6 may include a base frame and a housing mounted on the base frame. The slewing bearing 7 is mounted on the housing, and the main motor 8 is located inside the housing.
