Description

Technical Field

[0001] The invention relates to composite pipe production equipment, in particular to a winding machine. Background Art

[0002] To improve the mechanical properties of conveying pipes, a wrapping machine is typically used to wrap reinforcement materials such as steel strips and fiber strips around a plastic core tube to form a composite pipe. This wrapping machine primarily consists of a fixed frame and a turntable mechanism (rotating bracket) pivotally connected to it. As the plastic core tube is conveyed forward along the turntable mechanism's rotation axis, the turntable rotates the belt reel on it, releasing the reinforcement tape from the reel and wrapping it around the plastic core tube.

[0003] Existing winding machines can roughly complete the winding of reinforcement tape, but they suffer from problems such as poor product quality and large space requirements. In particular, when the turntable mechanism is configured with a large weight to improve production efficiency, the turntable mechanism's rotational stability is poor, resulting in the reinforcement tape not being wound uniformly around the plastic core pipe as expected, and the resulting composite pipe failing to meet service requirements.

[0004] For example, Chinese invention patent application 201610891934.8 discloses a winding machine for composite pipes and reinforced tapes. The main body of the machine is fixed with a first shaft cylinder extending from a cantilever. The second shaft cylinder of the turntable mechanism rotates with the first shaft cylinder through bearings, thereby driving the guide support mechanism and the belt guide device fixed thereto to rotate together about the rotation axis. The arms on the turntable mechanism for mounting the belt and reel device are cantilevered. In this case, the rotational stability of the belt and reel mechanism is poor, making it difficult to ensure the winding quality of large-diameter composite pipes.

[0005] In the above-mentioned prior art, the guide support mechanism is connected to the belt guide device via a guide rail slider, and the belt guide device is connected to a telescopic drive rod. Therefore, when the winding angle of the reinforcement tape needs to be adjusted, the telescopic drive rod drives the belt guide device to slide along the guide rail, thereby adjusting the guide rollers on the belt guide device to different angles of inclination relative to the extension direction of the core tube, thereby achieving adjustment of the winding angle. However, as the belt guide device slides, the winding machine occupies a large space along the length of the core tube, making the overall structure of the equipment bulky.

[0006] In view of this, it is necessary to provide a winding machine to solve at least some of the problems existing in the above-mentioned prior art. Summary of the Invention

DETAILED DESCRIPTION

[0041] The following describes the specific embodiments of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0042] In the present invention, unless otherwise specified, directional words such as "up, down, left, right" generally refer to up, down, left, right as shown in the reference drawings; "inside, outside" refer to inside and outside relative to the outline of each component itself.

[0043] Reference Figures 1 to 5 As shown, a winding machine according to a preferred embodiment of the present invention comprises a fixed frame 1 and a rotating support 3, wherein the rotating support 3 is rotatably connected to the fixed frame 1 via a slewing bearing 2. A tape reel 4 is mounted on the rotating support 3, and a core tube 6 can extend through the rotation axis of the rotating support 3 and be disengaged from the rotating support 3. Figure 1 The right side shown moves toward the left side, whereby when the rotating bracket 3 drives the belt reel 4 to rotate together, the reinforcing belt 5 on the belt reel 4 is released and wound onto the core pipe 6 to form a composite pipe.

[0044] In this preferred embodiment, combined Figure 7 As shown, the present invention utilizes a slewing bearing 2 to rotatably connect a rotating support 3 to a fixed frame 1, significantly improving winding quality and achieving other advantages. Specifically, the slewing bearing 2 comprises an inner ring 21, an outer ring 22, and rolling elements 23. One end of the slewing support 3 is fixedly connected to the outer ring 22. The inner ring 21 can be directly bolted to one side of the fixed frame 1, while the outer ring 22 is coaxially rotatably mounted on the outer periphery of the inner ring 21 via the rolling elements 23. The outer ring 22 is connected to a drive device (such as a reduction motor 43) to enable rotation along the outer periphery of the inner ring 21. Typically, the outer ring 22 of the slewing bearing 2 is formed with teeth, and the drive device can drive the outer ring 22 to rotate via a transmission gear 46 that meshes with the teeth. Consequently, when the reduction motor 43 is activated, the slewing support 3 rotates along with the outer ring 22 of the slewing bearing 2, winding the reinforcing tape 5 from the tape reel 4 onto the core tube 6.

[0045] As a large bearing capable of withstanding combined loads, the slewing bearing 2 can simultaneously withstand significant axial and radial loads and overturning moments, significantly improving the slewing stability of this winding machine. Compared to the prior art slewing mounting turntable mechanism that utilizes a fixed and rotating shaft cylinder mated with bearings, the present invention essentially connects the slewing support 3 more directly to the fixed frame 1. This reduces the impact of factors such as stiffness and dimensional parameters of the intermediate connector on slewing stability, facilitating the production of composite pipes with higher winding quality.

[0046] In particular, in large-diameter pipe manufacturing equipment, the traditional method of using bearings to mount a rotating bracket significantly increases equipment costs as the pipe diameter increases. Furthermore, machining the corresponding mounting holes in the fixed frame to accommodate the larger-diameter bearings places high demands on the processing equipment and machining accuracy. The present invention utilizes a slewing bearing 2 to effectively address these issues. This replacement of the intermediate connecting component can significantly reduce the manufacturing cost of large-diameter pipe winding machines and is expected to significantly enhance the product's market competitiveness.

[0047] In addition, by providing the slewing bearing 2, the connection between the rotating bracket 3 and the fixed frame 1 is relatively tight, the connection is more stable, and the structure is more compact. In comparison, the supporting function of the slewing bearing 2 is close to that of a bearing of the same size, but it is cheaper and more durable than a bearing. It is particularly suitable for use in a wrapping machine to slew the rotating bracket 3 to connect it to the fixed frame 1 when the rotating bracket 3 is heavy. Figure 7As can be seen, the portion of the fixed frame 1 connected to the rotating bracket 3 is typically formed into a box structure (to house the reduction motor 43, slip ring 8, etc.). However, with the slewing bearing 2 in place, the various loads during the rotation of the rotating bracket 3 primarily act on the inner side plate of the fixed frame 1 facing the rotating bracket 3. In this case, the thickness and rigidity of this inner side plate can be significantly greater than the other side plates to provide sufficient mounting foundation strength for the rotating bracket 3. Because, for example, the outer side plate opposite the inner side plate has a relatively small effect on the rotating bracket 3, in some embodiments, the outer side plate of the fixed frame 1 can even be omitted.

[0048] In the winding machine, the fixed frame 1 is used to connect the rotating bracket 3 and can also be connected to the structure for installing the rotating parts or fixed parts. Figure 4 and Figure 7 As shown, in a preferred embodiment, the wrapping machine further includes a rotating connector 7 and an inner fixed connector 9. The rotating connector 7 is driven to rotate along with the rotating bracket 3, and the inner fixed connector 9 is fixedly connected to the fixed frame. Specifically, the rotating connector 7 of the illustrated embodiment has an annular rim and a cylindrical portion. The annular rim is clamped between the rotating bracket 3 and the outer ring 22 of the slewing bearing 2, so that the rotating bracket 3 and the rotating connector 7 are fixedly connected to the outer ring 22 by bolts (refer to FIG. Figure 3 As shown, bolts are sequentially passed through the slewing bearing mounting bolt holes on the front end plate 31 of the rotating bracket 3 and the rotating connector 7 is threaded onto the outer ring 22 of the slewing bearing 2. The cylindrical portion extends around the rotation axis of the slewing bearing 2 and can be mounted with a slip ring 8, for example, to maintain electrical or signal connections between fixed components (such as a power supply) on the fixed frame 1 and the rotating connector 7 or rotating components on the rotating bracket 3 during rotation. To facilitate the installation of the internal fixed connector 9, the rotating connector 7 can be slewingly supported on the outer circumference of the internal fixed connector 9 via a bearing 10.

[0049] It is to be noted that since the rotating bracket 3, the rotating connector 7, etc. are all fixed relative to the outer ring 22 of the slewing bearing 2, they have a common rotation axis (such as Figure 1 Thus, the rotation axis described in the present invention can be generally understood as the rotation axis of the slewing bearing 2, which substantially coincides with the center line of the core tube 6.

[0050] Furthermore, the internal fixed connector 9 can be connected to an internal support frame 11, which extends away from the slewing bearing 2 to the inside of the rotating bracket 3, thereby accommodating fixed components such as the first tube stabilizing device 12 and the core tube heating device 56. The first tube stabilizing device 12 can limit the radial movement and / or rotation of the core tube 6 at the position where the reinforcing tape 5 is to be wound around it, thereby ensuring the central stability of the core tube 6 in the reinforcing tape winding section, facilitating the detection and accurate adjustment of the position of the reinforcing tape 5.

[0051] In addition, the winding machine of the present invention can also limit the radial and circumferential movement of the core tube 6 through the second tube stabilizing device 41 after the core tube 6 is wound with the reinforcement tape 5. Figures 4 to 6 As shown, the second tube stabilizing device 41 is arranged at the rear end of the rotating bracket 3 (in the preferred embodiment described later, that is, the side of the rear support frame 33 away from the front end plate 31), and the second tube stabilizing device 41 is adjustable to adapt to different tube diameters. Therefore, when winding reinforcement belts 5 of different thicknesses, the first tube stabilizing device 12 and the second tube stabilizing device 41 can be used to make the core tube 6 move stably along the rotation axis to ensure the winding quality.

[0052] The wrapping machine of the present invention can be equipped with a core tube heating device 56 and a reinforcement tape heating device 57 to facilitate efficient and reliable lamination of the two. As previously mentioned, the core tube heating device 56 can be mounted on the inner support frame 11 to heat the core tube 6 before the reinforcement tape 5 is wrapped around it. The reinforcement tape heating device 57 can be positioned just before the reinforcement tape 5 is wrapped around the core tube 6 and heats the side of the reinforcement tape 5 facing the core tube 6. This allows the surfaces of the reinforcement tape 5 and the core tube 6 to be partially melted, enabling a better lamination effect by leveraging their thermoplastic properties.

[0053] from Figure 4 It can be seen that the structure of the first tube stabilizing device 12 is basically the same as that of the second tube stabilizing device 41, except that an adjustment element is provided in the second tube stabilizing device 41. In some embodiments, the first tube stabilizing device 12 can also be set to the same adjustable form as the second tube stabilizing device 41 to adapt to the winding of the reinforcing tape of the core tube 6 with different diameters. In the illustrated embodiment, the second tube stabilizing device 41 includes a mounting column 41a, on which two vertically extending guide columns 41b are fixed. The upper and lower sides of the core tube 6 are respectively installed with an upper wheel 41c and a lower wheel 41d, whose axes are respectively perpendicular to the center line of the core tube 6, thereby limiting the radial displacement of the core tube 6 by the distance between the two, and preventing the core tube 6 from rotating by friction.

[0054] The lower wheel 41d is fixed relative to the mounting column 41a, and the upper wheel 41c can slide up and down along the guide column 41b. The height position of the upper wheel 41c is determined by adjusting the compression adjustment screw 41e, thereby clamping the core tube 6 between the upper wheel 41c and the lower wheel 41d with appropriate pressure.

[0055] In a preferred embodiment of the present invention, the rotating bracket 3 is formed in a frame form, which has a high overall rigidity and can make the forces on each arm 32 balanced during the rotation process, thereby ensuring the winding quality. Figures 1 to 5 As shown, the rotating bracket 3 includes a front plate 31, multiple arms 32, and a rear support frame 33. The front plate 31 can be connected to the outer ring 22 of the slewing bearing 2. Each arm 32 extends from the front plate 31 along the slewing axis and connects to the rear support frame 33 at the rear end, thus forming an overall frame structure. Each arm 32 can be mounted on a belt reel 4.

[0056] Compared with the cantilevered support arms in the prior art, the rotating bracket 3 of the preferred structural form of the present invention can ensure that the forces on each support arm 32 are balanced during the rotation process, thereby avoiding uneven forces during rotation caused by one end of the support arm 32 being suspended in the air. This not only significantly improves the winding quality of the reinforcing belt 5, but also improves the operational safety during equipment operation.

[0057] The tape reels 4 are mounted on each arm 32 and are capable of releasing the reinforcement tape 5. In the illustrated preferred embodiment, to conserve installation space, each arm 32 is offset from the rotation axis and laterally connected to a reel connector 13, on which the tape reels 4 are mounted. This shortens the distance between the reels 4 and the rotation axis, preventing them from protruding excessively from the arms 32, allowing them to rotate within a smaller space. By offsetting the arms 32 from the rotation axis, the centerline of the tape reels 4 can be conveniently extended in a direction passing through the rotation axis, while simultaneously achieving a smaller rotation radius, effectively improving rotational stability and winding balance.

[0058] Furthermore, the axes of the reels 4 are located in the same plane as the rotation axis and are perpendicular to the rotation axis. That is, in the embodiment shown in the figure with four arms 32 arranged opposite to each other, the axes of the reels 4 on the opposite arms 32 can overlap and form a cross shape crossing the rotation axis, as shown in FIG. Figure 3 This arrangement not only enables the rotating bracket 3 to maintain its center of gravity on the rotation axis at any rotation position thereof and any rotation position of the reel 4, thereby improving the winding quality, but also avoids an increase in the rotation space requirement due to the tilted arrangement of the reel 4.

[0059] It will be appreciated that in order to form a frame-type rotating bracket 3, the key to the present invention lies in connecting the rear supports 33 to the tail ends of the arms 32 to prevent their respective tail ends from hanging in the air. For example, an octagonal rear support 33 connects the tail ends of each arm 32, and the number of arms 32 is not limited to four. For example, in an alternative embodiment, three arms 32 may be provided between the front plate 31 and the rear support 33 to form a triangular frame structure. In the preferred embodiment shown, by configuring the rear support 33 in an octagonal shape, sharp corners are avoided and manufacturing is facilitated.

[0060] In order to wind the reinforcing tape 5 from the reel 4 onto the core tube 6 in a predetermined manner, guide rollers and brackets for mounting the guide rollers are typically provided on the support arm 32. In the present invention, an L-shaped bracket 14 is slidably connected to the support arm 32, serving as a support for at least some of the guide rollers (other guide rollers can be directly connected to the support arm 32). The two bracket arms of the L-shaped bracket 14 are perpendicular to the rotation axis. Thus, by sliding the L-shaped bracket 14 along the support arm 32, the guide rollers can be used to guide the reinforcing tape 5 to different locations on the core tube 6 for winding. Furthermore, because the two bracket arms are perpendicular to the rotation axis, the overall arrangement can be relatively close to the rotation axis, thus minimizing space consumption.

[0061] The guide roller of the present invention includes a tension roller group 15 and an angle detection and adjustment roller 16. The former can make the conveyed reinforcement belt 5 have appropriate tension, and the latter can make the reinforcement belt 5 evenly wound at a predetermined angle. Figure 8 As shown, the tension roller group 15 includes a first guide roller 15a, a second guide roller 15b, and a tension detection roller 15c distributed in a triangular shape, which are arranged on the same side of the rotating bracket 3 as the corresponding tape reel 4. After being output from the tape reel 4, the reinforcement tape 5 is guided by the guide rollers until it contacts the lower side of the first guide roller 15a, then contacts the upper side of the tension detection roller 15c, and then contacts the lower side of the second guide roller 15b. As a result, its tension is applied to the tension detection roller 15c so that it can be detected and adjusted.

[0062] Figure 9 and Figure 10The figure shows a reinforcement belt angle detection and adjustment device provided with an angle detection and adjustment roller 16, including a roller frame 19 and an angle detection and adjustment roller 16 pivotally connected to the roller frame 19, etc. The roller frame 19 can be connected to an L-shaped bracket by, for example, a mounting frame 47. In order to allow the reinforcement belt 5 to be wound onto the core tube 6 at an appropriate angle, the roller shaft of the angle detection and adjustment roller 16 has an inclination angle relative to the axis of rotation, and tension sensors 18, such as through-axis tension sensors, are installed at both ends to be able to detect the fit between the reinforcement belt 5 and the angle detection and adjustment roller 16. When the reinforcement belt 5 tilts relative to the angle detection and adjustment roller 16 and warps, the force exerted on the angle detection and adjustment roller 16 by one side is smaller, and thus the direction of its roller shaft needs to be adjusted. To this end, an adjustment motor 20 can be connected to the roller frame 19 to move the angle detection and adjustment roller 16 along the axis when the tension sensor 18 detects that the reinforcement belt 5 fails to fit well with the angle detection and adjustment roller 16. Figure 9 The angle detection and adjustment roller 16 rotates in the direction indicated by the arrow, ensuring that the reinforcement tape 5 is evenly guided at the predetermined angle, guaranteeing winding quality and enabling the reinforcement tape 5 to effectively perform its reinforcing function after winding. After passing through the angle detection and adjustment roller 16, the reinforcement tape 5 is helically wound around the core tube 6 in a direction perpendicular to the roller axis. An edge detector 44 can be installed near the winding position to determine the winding position of the reinforcement tape 5, improving controllability of product types, etc.

[0063] The L-shaped bracket 14 can be slidably connected to the support arm 32 in a variety of suitable ways. For example, a slide groove can be formed on the support arm 32, and the L-shaped bracket 14 can be connected to a roller that slides within the slide groove. In the preferred embodiment shown in the figure, a pair of guide rails 17 extending parallel to the rotation axis are fixedly connected to the support arm 32. The L-shaped bracket 14 is connected to the guide rails 17 via guide rail sliders, allowing it to slide along the guide rails 17 to adjust the winding position of the reinforcement belt 5.

[0064] Figure 11 and Figure 12 The following diagrams illustrate a partial structure of a wrapping machine according to another preferred embodiment of the present invention, viewed from different angles. Unlike the previous embodiment, the rotating support 3 of this wrapping machine comprises a pair of parallel arms 32 extending parallel to the axis of rotation. Each pair of arms 32 is equipped with a reel mounting bracket 53, which overlaps the arms 32 through a parallel gap. The reels 4 are mounted on the arms 32 via the reel connectors 13, with their rotational axes and rotational axes coplanar when releasing the reinforcing tape 5. Specifically, the reels' axes of rotation extend into the parallel gaps between the arms 32.

[0065] Compared with the aforementioned single-arm support arm, this preferred embodiment utilizes support arms 32 on both sides of the rotating shaft of the tape reel 4 to provide support, which can effectively improve the overall structural strength and ensure good winding quality.

[0066] Furthermore, the support arms 32 may be provided with an axially slidable belt guide mechanism mounting plate 48. The belt guide mechanism mounting plate 48 is provided with a tension roller set 15 and an angle detection adjustment roller 16 for guiding the reinforcement belt 5. The belt guide mechanism mounting plate 48 is arranged such that the reinforcement belt 5 extends through the parallel gap between the support arms 32 toward a position close to the core tube 6. It is understood that various technical features of the aforementioned preferred embodiment may be applied to this preferred embodiment. For example, the rotating bracket 3 may also be formed as a frame-type structure having a front end plate and a rear support frame, and details thereof will not be repeated here.

[0067] Figure 13 and Figure 14 A belt reel installation structure of a slant-disc arrangement winding machine is provided, which can shorten the overall length of the winding machine. Specifically, in this preferred embodiment, the belt reel 4 is arranged obliquely relative to the rotation axis of the rotating bracket 3, that is, the rotation axis of the belt reel 4 when releasing the reinforcing belt 5 is not perpendicular to the rotation axis, forming a slant-disc arrangement winding machine. Usually, the belt reel 4 is arranged so that its rotation axis is coplanar with the rotation axis of the rotating bracket 3. Among them, the belt reel installation adjustment mechanism includes a first telescopic drive member 49 and a second telescopic drive member 50 that are telescopic in a manner parallel to the rotation axis and are installed on the rotating bracket 3 at intervals from each other in the rotation radial direction. The output ends of the first telescopic drive member 49 and the second telescopic drive member 50 are respectively connected to the belt reel 4 and can adjust the axial position of the belt reel 4 on the rotating bracket 3 and the inclination angle relative to the rotation axis.

[0068] Thus, the reel installation adjustment mechanism can adjust the axial position of the reel 4 by synchronously extending and retracting the first and second retractable drive members 49, 50, and can adjust the inclination angle of the reel 4 by activating at least one of the first and second retractable drive members 49, 50. Because both the first and second retractable drive members 49, 50 extend and retract in a direction parallel to the rotation axis of the rotating bracket 3 and are more directly connected to the rotating bracket 3, the rotating bracket 3 can be used to constrain its irrational movement, thereby providing greater robustness and reliability, and effectively improving the reel adjustment stability and winding quality.

[0069] To this end, Figure 1In the preferred embodiment shown, the rotating bracket 3 includes a plurality of arms 32 extending in a direction parallel to the axis of rotation and mounting seats 34 protruding radially from the arms 32. Axial slide rails 51 are provided on the arms 32 and mounting seats 34, respectively. Each axial slide rail 51 is coupled to a corresponding slide 52, which is transmission-connected to a reel mounting frame 53 on which the reels 4 are mounted. A first telescopic drive member 49 is mounted on the mounting seat 34, and a second telescopic drive member 50 extends relatively close to the arms 32, so that the two are spaced apart from each other in the radial direction of rotation. The output ends of the first telescopic drive member 49 and the second telescopic drive member 50 are respectively connected to the slides 52 so as to be able to push them to slide in a direction parallel to the axis of rotation, thereby adjusting the axial position and tilt angle of the reel mounting frame 53 and the reels 4 thereon. One end of the first telescopic drive member 49 is connected to the mounting seat 34, and the other end is connected to the slide 52; one end of the second telescopic drive member 50 is connected to the support arm 32 or the front end plate 31 described later, and the other end is connected to the slide 52, thereby enabling the first telescopic drive member 49 and the second telescopic drive member 50 to stably telescope along the axial direction through the cooperation of the slide 52 and the axial slide rail 51, thereby facilitating accurate adjustment of the axial position and tilt angle.

[0070] In the present invention, the first telescopic drive member 49 and the second telescopic drive member 50 can be any appropriate form of power components, such as hydraulic cylinders, air cylinders, etc. Preferably, both can be electric cylinders to avoid reliability problems caused by oil and gas leakage.

[0071] exist Figure 13 The illustrated reel installation adjustment mechanism further includes a connecting arm 54 connected between a slide 52 (mounted on the mounting seat 34) and a reel mounting frame 53. The reel mounting frame 53 is hingedly connected to the connecting arm 54 and the slide 52 mounted on the support arm 32 at spaced-apart positions. Thus, when the first and second telescopic drive members 49, 50 are synchronously extended and retracted, the two slides 52 are driven to move the reel mounting frame 53 and the reel 4 axially as a whole, thereby adjusting the axial position. When the second telescopic drive member 50 is kept stationary and only the first telescopic drive member 49 is activated to extend and retract, the reel mounting frame 53 will flip around its hinge point with the slide 52 mounted on the support arm 32, thereby adjusting the tilt angle.

[0072] Continue to refer to Figure 13 As shown, the rotating bracket 3 also includes a front end plate 31 for rotatably connecting to the fixed frame 1. A plurality of support arms 32 extend axially from the front end plate 31 in the direction of movement of the core tube 6. The mounting seat 34 is arranged at the end of the support arm 32 connected to the front end plate 31. This allows the tape reel 4 to be as close to the front end plate 31 as possible, shortening the overall axial length of the winding machine and preventing the equipment from being too heavy and occupying too much space.

[0073] Furthermore, the reel mounting frame 53 is typically equipped with a plurality of tension rollers 15 for guiding the released reinforcement tape 5 to the core tube 6. In the present invention, at least some of the tension rollers can be positioned behind the axial ends of the support arms 32. This allows the tension rollers to stably guide the reinforcement tape 5 to the core tube 6 while reducing the space occupied by the winding machine.

[0074] Figure 14 The figure shows the installation structure diagram of the reel installation adjustment mechanism according to another preferred embodiment of the present invention, which is the same as the above Figure 13 The preferred embodiments shown are basically the same, and the following mainly describes the differences therebetween.

[0075] In this preferred embodiment, a slide groove 55 is provided on the reel mounting frame 53, and the slide 52 provided on the mounting seat 34 is transmission-connected to the reel mounting frame 53 via the slide groove 55. For example, a pin capable of axially sliding with the slide 52 can be provided in the slide groove 55. When the first telescopic driving member 49 telescopes, the pin moves axially and slides in the slide groove 55, thereby driving the reel mounting frame 53 to flip around the hinge point between the reel mounting frame 53 and the slide 52 provided on the support arm 32, thereby adjusting the tilt angle.

[0076] Preferably, the rotating bracket 3 in the wrapping machine can be rotatably mounted to the fixed frame 1 via the slewing bearing 2. This allows for a wrapping machine capable of producing large-diameter composite pipes at significantly lower costs and processing design requirements, with advantages such as ease of use and high reliability. Typically, the wrapping machine can be provided with four or six tape reels 4, each mounted via the aforementioned tape reel mounting and adjustment mechanism.

[0077] The preferred embodiments of the present invention and the advantages of various improved technologies in improving the performance of winding machines have been described in detail above, in conjunction with the accompanying drawings. However, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple variations, including the combination of various specific technical features in any suitable manner. To avoid unnecessary repetition, the present invention will not further describe various possible combinations. However, these simple variations and combinations should also be considered as the contents disclosed by the present invention and fall within the scope of protection of the present invention.
