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:

[0005] A rotatable turntable;

[0006] Multiple strip-shaped support plates extend from the turntable in the same direction along the axial direction of the turntable, and the multiple support plates are arranged around the central axis of the turntable to form a support structure for winding products;

[0007] A first stop lever is connected to the first axial end of the support plate away from the turntable and extends outward along the radial direction of the turntable;

[0008] The support plate is movable relative to the turntable in the radial direction of the turntable to reduce the outer diameter of the support structure, and the first stop is rotatable relative to the turntable such that the radial dimension of the first stop is less than or equal to the radial dimension of the support structure, thereby allowing the product wrapped around the support structure to be removed from the support structure.

[0009] In some embodiments, the system further includes multiple sets of linear guide rail assemblies arranged radially on the turntable, with multiple support plates correspondingly arranged on each set of linear guide rail assemblies and capable of moving radially along the linear guide rails.

The lead screws are rotatably mounted on the turntable and screwed to the support plate, and the plurality of lead screws are drivenly connected to at least one drive member.

[0011] In some embodiments, the system further includes sprockets disposed on the turntable and connected to the plurality of lead screws in a one-to-one transmission manner. The plurality of sprockets are sequentially connected by a chain, and only one of the sprockets is connected to one of the driving components.

[0012] In some embodiments, the central axis of the sprocket is parallel to the central axis of the turntable, and the sprocket is connected to the lead screw via a torque reversing structure.

[0013] In some embodiments, the first stop is rotatably connected to the axial first end of the support plate via a hinge shaft extending in the tangential direction.

[0014] In some embodiments, the device further includes a telescopic drive member disposed on the support plate and a connecting rod with its two ends respectively connected to the first stop and the telescopic drive member. The telescopic drive member is capable of telescopic extension and retraction to drive the first stop to rotate around the hinge axis via the connecting rod.

[0015] In some embodiments, a second stop extending radially outward from the support plate is further included, the second stop being axially spaced from the first stop to define the axial dimension of the product to be wound.

[0016] In some embodiments, the support plate is provided with a plurality of axially spaced mounting points, and the second stop is selectively mounted on one of the mounting points to change the axial dimension of the product to be wound.

[0017] In some embodiments, the system further includes a rotating shaft connected to the turntable, a slip ring disposed on the rotating shaft, and a rotary air connector.

[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. The main motor is connected to the drive gear to provide rotational power to the slewing bearing.

[0019] The above technical solution allows products to be directly wound onto the winding assembly and easily removed, simplifying the winding machine structure. It also eliminates the need for additional winding reels and provides space for them, saving on transportation costs. Therefore, it can significantly reduce costs. Attached Figure Description

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 1-6 As shown, this solution provides a winding component, including:

[0030] Rotatable turntable 1;

[0031] Multiple strip-shaped support plates 3 extend from the turntable 1 in the same direction along the axial direction of the turntable 1, and the multiple support plates 3 are arranged around the central axis of the turntable 1 to form a support structure for winding products;

[0032] The first stop 4 is connected to the first axial end of the support plate 3 away from the turntable 1 and extends outward along the radial direction of the turntable 1.

[0033] The support plate 3 is movable relative to the turntable 1 in the radial direction of the turntable 1 to reduce the outer diameter of the support structure, and the first stop 4 is rotatable relative to the turntable 1 such that the radial dimension of the first stop 4 is less than or equal to the radial dimension of the support structure, thereby allowing the product wrapped around the support structure to be removed from the support structure.

[0034] Turntable 1 serves as the basic support for the winding assembly. Support plates 3 are located on the same side of turntable 1. Multiple support plates 3 are arranged circumferentially around the central axis of turntable 1 to form a support structure. The product can be wound onto the support structure. The outer surface of the support plate 3 can serve as the support surface for the product 24. The outer surface of the support plate 3 can be formed as an arc-shaped surface around turntable 1. (Refer to...) Figure 1 and 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 support plate 3 can be mounted on the bracket 6. The support plate 3 can be directly connected to other components, or it can be connected or cooperated with other components through the bracket 6. For example, the support plate 3 can be slidably mounted on the turntable 1 (or other structures on the turntable 1) through the bracket 6.

[0036] The first stop 4 is located at the first axial end of the support plate 3. During product winding, the first stop 4 acts as a stop and limit mechanism, preventing the product 24 from falling off the first axial end of the support structure (corresponding to the first axial end of the support plate 3). (Refer to...) Figure 1 and Figure 2 As shown.

[0037] The support plate 3 can move radially relative to the turntable 1, including radial inward and radial outward movement. When the product winding is complete, the winding assembly can be... Figure 4 and Figure 5 The shown winding state is converted to Figure 6In the shown take-up state, the support plate 3 can move radially inward, which reduces the overall outer diameter of the support structure and separates the support plate 3 from the wound product. Furthermore, the first stop 4 can rotate relative to the support plate 3 so that its radial dimension is less than or equal to the radial dimension of the support structure. The radial dimension of the first stop 4 refers to the radial distance between its outermost radial portion and the central axis of the turntable 1. The radial dimension of the support structure is the radial distance between the outer periphery of the support structure and the central axis of the turntable 1 (the overall outer diameter of the support structure). In other words, the first stop 4 does not protrude radially outward relative to the support structure, and it no longer restricts the axial movement of the product 24, allowing the product 24 to be removed from the support structure in the direction towards the first axial end. Therefore, a detachable take-up reel for winding the product is no longer needed on the take-up assembly.

[0038] After the product is removed from the winding assembly, the support plate 3 can be moved radially outward relative to the turntable 1, thereby increasing the outer diameter of the support structure, and the first stop 4 can be rotated back to the position extending radially outward from the support plate 3.

[0039] Before winding the product, the radial position of the support plate 3 can be adjusted as needed, that is, the outer diameter of the support structure can be adjusted as needed, as long as the outer diameter of the support structure is greater than its minimum achievable outer diameter, that is, as long as the support plate 3 is not in the radially inward extreme position (at the extreme position, the distance between the support plate 3 and the central axis of the turntable 1 is the smallest).

[0040] This solution allows products to be directly wound onto the winding assembly and easily removed, simplifying the winding machine structure. It also eliminates the need for additional winding reels and provides space for them, saving on transportation costs. Therefore, it can significantly reduce costs.

[0041] In some embodiments, the winding assembly further includes multiple sets of linear guide rail assemblies 9 arranged radially on the turntable 1. Multiple support plates 3 are correspondingly arranged on each set of linear guide rail assemblies 9 and are capable of radial movement along the linear guide rail assemblies 9. Each support plate 3 corresponds to a set of linear guide rail assemblies 9, and the linear guide rail assemblies 9 can guide the support plate 3 to move radially. (Refer to...) Figure 1 and Figure 2As shown, the turntable 1 is provided with multiple slide frames 2 corresponding to multiple support plates 3. Each set of linear guide rail assemblies 9 may include one or more guide rails. In some embodiments, the support plates 3 are mounted on a bracket 6, and a movable seat 10 is provided at one end of the bracket 6 near the slide frame 2. The movable seat 10 is slidably mounted on the linear guide rail assembly 9, and the slide frame 2 is fixedly mounted on the turntable 1. In addition, a reinforcing support rod 15 is connected between the movable seat 10 and the end of the bracket 6 away from the turntable 1 to provide stable support for the bracket 6.

[0042] In some embodiments, the winding assembly further includes a plurality of lead screws 7 corresponding one-to-one with each of the linear guide assemblies 9 and extending radially. The lead screws 7 are rotatably mounted on the turntable 1 and screwed to the support plate 3. The plurality of lead screws 7 are drively connected to at least one drive member 8. Each lead screw 7 corresponds to a set of linear guide assemblies 9. The lead screw 7 has an external thread, and the fixing nut connected to the support plate 3 has a corresponding internal thread. The lead screw 7 and the support plate 3 form a lead screw mechanism. The drive member 8 can drive the lead screw 7 to rotate, thereby driving the support plate 3 to move radially. As described above, the support plate 3 can be mounted on the bracket 6, and the bracket 6 is mounted on the movable seat 10. Therefore, in some embodiments, the lead screw 7 can be screwed to the movable seat 10, which can also drive the support plate 3 to move radially. Alternatively, the lead screw 7 can also be mounted on the slide frame 2 described above. The cooperation between the lead screw 7 and the support plate 3 (or the movable seat 10) can also lock the support plate 3, that is, when the lead screw 7 stops rotating, the support plate 3 can remain radially fixed. Among them, the driving component 8 can be an electric motor, hydraulic motor, etc.

[0043] Of course, in other embodiments, the support plate 3 can be moved radially by a hydraulic cylinder or a pneumatic cylinder, or the support plate 3 can be moved manually. The support plate 3 can be locked in different positions by friction, or a locking element can be provided on the support plate 3 (or the moving seat 10) to lock it on the linear guide assembly 9.

[0044] In some embodiments, the winding assembly further includes sprockets 11 disposed on the turntable 1 and driven in a one-to-one manner with the plurality of lead screws 7. The plurality of sprockets 11 are sequentially connected by a chain 12, and only one of the sprockets 11 is driven in a single drive member 8. (Reference) Figure 4As shown, the sprocket assembly 11 includes two coaxially arranged sprockets. Each of the two sprockets is connected to a sprocket of a circumferentially adjacent sprocket assembly 11 via a chain 12, thus enabling the multiple sprocket assemblies 11 to be connected. When the driving member 8 drives one of the sprocket assemblies 11 to rotate, the other sprocket assemblies 11 also rotate synchronously. Therefore, multiple lead screws 7 can be driven to rotate synchronously, thereby driving the support plates 3 to move radially synchronously. In this embodiment, only one driving member 8 is needed to synchronously drive multiple support plates 3 to move radially, reducing the number of driving members 8 and ensuring the synchronicity of the multiple support plates 3.

[0045] In some embodiments, the central axis of the sprocket 11 is parallel to the central axis of the turntable 1, and the sprocket 11 is connected to the lead screw 7 via a torque reversing structure 16. Since the central axis of the sprocket 11 is perpendicular to the lead screw 7, the torque reversing structure 16 is needed as the torque transmission medium between them. The torque reversing structure 16 may include two meshing bevel gears, whose central axes are perpendicular to each other and coaxially connected to the sprocket 11 and the lead screw 7, thus enabling torque reversal.

[0046] In some embodiments, the first stop 4 is rotatably connected to the axial first end of the support plate 3 via a hinge axis extending tangentially. The first stop 4 can rotate about an axis extending tangentially, for example, it can rotate so that its extension direction is parallel to the central axis of the turntable 1, allowing the product 24 on the support plate 3 to move axially past the first stop 4, thus removing the product 24 from the support structure. In other embodiments, the first stop 4 can also be hinged to the bracket 6. When it is necessary to rewind the product, the first stop 4 can be rotated back to a position where its extension direction is radial.

[0047] In some embodiments, the winding assembly further includes a telescopic drive member 13 disposed on the support plate 3 and a connecting rod 14 with its two ends respectively connected to the first stop rod 4 and the telescopic drive member 13. The telescopic drive member 13 is telescopic to drive the first stop rod 4 to rotate around the hinge axis via the connecting rod 14. Each support plate 3 is provided with a telescopic drive member 13, one end of which is hinged to the support plate 3 (or bracket 6), and the other end is hinged to the connecting rod 14. The connecting rod 14 is connected to the first stop rod 4 (for example, the first stop rod 4 is hinged to one end of the support plate 3). The telescopic movement of the telescopic drive member 13 can cause the first stop rod 4 to rotate, that is, to rotate between a radially extending position and an axially extending position. The telescopic drive member 13 can be a hydraulic cylinder, a pneumatic cylinder, etc.

[0048] Additionally, in some embodiments, the winding assembly further includes a second stop 5 extending radially outward from the support plate 3. The second stop 5 is axially spaced from the first stop 4 to define the axial dimension of the product to be wound. The second stop 5 is disposed on the support plate 3, axially spaced from the first stop 4, and the product 24 can be wound between them. The distance between the first stop 4 and the second stop 5 is the winding width (overall axial dimension) of the product being wound.

[0049] In some embodiments, the support plate 3 is provided with multiple axially spaced mounting points, and the second stop 5 is selectively mounted on one of these mounting points to change the axial dimension of the product to be wound. When the second stop 5 is mounted on different mounting points, the distance between the first stop 4 and the second stop 5 is different, thus the winding width (overall axial dimension) of the product to be wound can be changed to adapt to different needs. The second stop 5 can be inserted into the support plate 3 or connected to the support plate 3 by bolts. Of course, the second stop 5 can also be mounted on the bracket 6.

[0050] In some embodiments, the winding assembly further includes a rotating shaft 23 connected to the turntable 1, a slip ring 17 disposed on the rotating shaft 23, and a rotary air connector 18. The turntable 1 and the rotating shaft 23 are coaxially arranged and rotate synchronously. The slip ring 17 can cooperate with the brush to realize power transmission, thereby providing power to the drive component 8, etc. The rotary air connector 18 can rotatably cooperate with the fixed air connector to receive air pressure transmission, thereby driving the telescopic drive component 13 to operate.

[0051] On the other hand, this solution also provides a winding machine, which includes a frame 19, a slewing bearing 20 mounted on the frame 19, a main motor 21, and the winding assembly described in the above solution. The winding assembly is rotatably mounted on the slewing bearing 20 about a central axis. The outer gear ring of the slewing bearing 20 meshes with a drive gear. The main motor 21 is connected to the drive gear to provide rotational power to the slewing bearing 20. A turntable 1 can be mounted on the slewing bearing 20. The rotatable part of the slewing bearing 20 is provided with an outer gear ring. The main motor 21 can be mounted on the frame 19. The output end of the main motor 21 can be driven (e.g., through a reducer, transmission component, etc.) to the drive gear meshing with the outer gear ring. The main motor 21 can drive the slewing bearing 20 and the turntable 1 to rotate. The frame 19 can also be provided with a brush that cooperates with a slip ring 17 and a fixed air connector that cooperates with a rotary air connector 18. A housing 22 can be installed on the frame 19, and the main motor 21, brushes, fixed air connectors, etc. can be installed in the housing 22.
