Description

Technical Field

[0001] The utility model relates to pipeline manufacturing equipment, in particular to a tape reel installation and adjustment mechanism of a winding machine. On this basis, the utility model also relates to a winding machine. Background Art

[0002] To improve the mechanical properties of conveying pipes, a winding 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 machine primarily consists of a fixed frame and a turntable mechanism (rotating frame) pivotally connected to it. As the plastic core tube is conveyed forward along the turntable mechanism's rotation axis, the turntable mechanism rotates the belt reel on it and releases the reinforcement tape from the reel, wrapping it around the plastic core tube.

[0003] Belt winding machines in the prior art typically use telescopic drive components, such as electric cylinders and electric push rods, to adjust the axial position of the belt reel relative to a rotating frame and / or the inclination angle of the belt reel relative to the rotation axis of the rotating frame. For example, Chinese utility model patent CN206406447U provides a position and angle control system for a winding machine, in which a belt reel moving frame is mounted on a guide rail pair and can be driven by a servo motor to move back and forth along a ball screw to adjust the axial position of the belt reel; an electric cylinder is connected between the belt reel mounting frame and the belt reel moving frame. When the winding angle needs to be changed, the electric cylinder is controlled to extend and retract so that the belt reel rotates relative to the belt reel mounting frame along with the belt reel mounting frame, thereby changing the angle between the belt reel axis and the rotation axis of the rotating frame.

[0004] For another example, Chinese utility model patent CN210283261U discloses a tape reel installation and adjustment mechanism for a winding machine, comprising a first telescopic drive member and a second telescopic drive member, such as an electric cylinder, which are telescopically extended in a direction parallel to the rotation axis of the rotating frame and installed on the rotating frame at intervals from each other in the rotation radial direction. The output ends of the first telescopic drive member and the second telescopic drive member are transmission-connected to the tape reel and can adjust the axial position of the tape reel on the rotating frame and the inclination angle relative to the rotation axis of the rotating frame.

[0005] However, in the above-mentioned prior art, when the tape reel runs to the highest or lowest position, due to its greater gravity, the telescopic drive member such as the electric push rod and its various hinge points are squeezed or stretched. Since the internal components of the telescopic drive member (such as the screw rod in the electric push rod) themselves have gaps, each hinge point also has manufacturing and installation gaps, which will cause periodic fluctuations in the tape reel angle during the rotation of the tape reel. When the reinforcement tape is wound onto the surface of the core material, this fluctuation is amplified, resulting in the reinforcement tape winding gap cannot be accurately maintained, poor consistency, and seriously affecting product quality. Utility Model Content

[0006] The purpose of the present utility model is to overcome the problem in the prior art that the winding gap of the reinforcement belt is difficult to be accurately maintained due to the periodic fluctuation of the belt reel angle during the rotation of the belt reel, thereby affecting the product quality. The utility model provides a belt reel installation and adjustment mechanism for a winding machine, which can limit the squeezing of the telescopic drive member and its various hinge points by the gravity of the belt reel during the rotation of the belt reel, so as to reduce or eliminate the periodic fluctuation of the belt reel angle caused by the gap between the telescopic drive member itself and the hinge point, so as to facilitate the accurate maintenance of the winding gap of the reinforcement belt wound onto the core pipe and the product quality of the composite pipe obtained.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] The following will describe in detail the specific embodiments of the present utility model in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present utility model, and are not intended to limit the present utility model.

[0033] Referring to Figures 1 to 5 the various different embodiments shown, an aspect of the present utility model provides a reel mounting and adjusting mechanism for a winding machine. The winding machine includes a fixed frame and a rotating frame 1 rotatably mounted (such as through a slewing bearing) on the fixed frame. The reel mounting and adjusting mechanism is disposed on the rotating frame 1 and is mounted with a reel 8 arranged obliquely relative to the axis of rotation of the rotating frame 1, that is, the axis of rotation of the reel 8 when releasing the reinforcing tape is not perpendicular to the axis of rotation, forming an inclined reel arrangement type winding machine. The core tube can extend through the axis of rotation of the rotating frame 1 and move from the right side shown in the figure to the left side. Thus, when the rotating frame 1 drives the reel 8 to rotate together, the reinforcing tape on the reel 8 is released and wound around the core tube to form a composite pipe.

[0034] Among them, the reel mounting and adjusting mechanism includes a telescopic driving member 3 and a gas spring 4. The telescopic driving member 3 is arranged to be able to adjust the axial position of the reel 8 on the rotating frame 1 and / or the inclination angle relative to the axis of rotation of the rotating frame 1; the gas spring 4 is connected in parallel relative to the telescopic driving member 3. The gas spring is a commonly used industrial accessory for functions such as support, buffering, system, height adjustment, and angle adjustment. By connecting the gas spring 4 in parallel with the telescopic driving member 3 for adjusting the position (especially the inclination angle) of the reel 8, the gas spring 4 can be used to support and hold the reel 8 in a predetermined position. When the reel runs to the highest position, the supporting force of the gas spring 4 is used to offset the component force of the gravity of the reel 8 in the telescopic direction of the telescopic driving member 3, so that the reel 8 is always supported by the gas spring 4, avoiding the telescopic driving member and its various hinge points from being squeezed and causing the reel 8 to have a small movement; when the reel runs to the lowest position, the reel 8 is held in a preset position under the combined action of its own gravity and the supporting force of the gas spring 4. Thus, during the rotation of the reel, under the supporting action of the gas spring 4, the telescopic driving member and its various hinge points always maintain the same matching and connection state, which reduces or eliminates the periodic fluctuation of the reel angle caused by the squeezing action of the reel gravity on the telescopic driving member, so as to accurately maintain the winding gap of the reinforcing tape wound around the core tube and the product quality of the obtained composite pipe.

[0035] Referring to Figure 1As shown, in the first preferred embodiment, the belt reel installation and adjustment mechanism includes a first telescopic drive member 31 and a second telescopic drive member 32 which are telescopically extended in parallel to the rotation axis and are installed on the rotating frame 1 at intervals from each other in the rotation radial direction. The output ends of the first telescopic drive member 31 and the second telescopic drive member 32 are respectively connected to the belt reel 8 and can adjust the axial position of the belt reel 8 on the rotating frame 1 and the inclination angle relative to the rotation axis.

[0036] Thus, the reel installation adjustment mechanism can adjust the axial position of the reel 8 by synchronously extending and retracting the first and second retractable drive members 31, 32, and can adjust the inclination angle of the reel 8 by activating at least one of the first and second retractable drive members 31, 32. Because both the first and second retractable drive members 31, 32 extend and retract in a direction parallel to the rotation axis of the rotating frame 1 and are more directly connected to the rotating frame 1, the rotating frame 1 can be used to constrain irrational movement, providing greater robustness and reliability, effectively improving reel adjustment stability and winding quality.

[0037] To this end, in Figure 1 In the preferred embodiment shown, the rotating frame 1 includes a plurality of arms 11 extending in a direction parallel to the axis of rotation and mounting seats 12 protruding radially from the arms 11. The arms 11 and mounting seats 12 are fixed to each other and are respectively provided with axial slide rails 5. Each axial slide rail 5 is cooperatively connected to a corresponding slide 6, and the slide 6 is transmission-connected to the reel mounting frame 7 on which the reel 8 is mounted. The first telescopic drive member 31 is mounted on the mounting seat 12, and the second telescopic drive member 32 extends at a position relatively close to the arm 11, 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 31 and the second telescopic drive member 32 are respectively connected to the slide 6 so as to be able to push it to slide in a direction parallel to the axis of rotation, thereby adjusting the axial position and tilt angle of the reel mounting frame 7 and the reel 8 thereon. One end of the first telescopic drive member 31 is connected to the mounting seat 12, and the other end is connected to the slide 6; one end of the second telescopic drive member 32 is connected to the support arm 11 (front end plate), and the other end is connected to the slide 6, thereby enabling the first telescopic drive member 31 and the second telescopic drive member 32 to stably telescope along the axial direction through the cooperation of the slide 6 and the axial slide rail 5, thereby facilitating accurate adjustment of the axial position and inclination angle.

[0038] In the present invention, the first telescopic driving member 31 and the second telescopic driving member 32 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.

[0039] exist Figure 1In the tape reel mounting and adjusting mechanism shown, it further includes a connecting arm (not marked) connected between the sliding seat 6 (mounted on the mounting base 12) and the tape reel mounting bracket 7. The tape reel mounting brackets 7 are respectively hinged to the connecting arm and the sliding seat 6 provided on the support arm 11 at positions spaced from each other. Thus, when the first telescopic driving member 31 and the second telescopic driving member 32 telescopically move synchronously, the two sliding seats 6 are driven to drive the tape reel mounting bracket 7 and the tape reel 8 as a whole to axially move, realizing the adjustment of the axial position. When the second telescopic driving member 32 is kept stationary and only the first telescopic driving member 31 is started to telescopically move, the tape reel mounting bracket 7 will flip around the hinge point with the sliding seat 6 provided on the support arm 11 as the center point, realizing the adjustment of the tilt angle.

[0040] In this preferred embodiment, the gas springs 4 of the tape reel mounting and adjusting mechanism include a first gas spring 41 and a second gas spring 42. Among them, the two ends of the first gas spring 41 are respectively hinged to the mounting base 12 and the sliding seat 6 provided on the mounting base 12 to be in parallel connection relative to the first telescopic driving member 31; the two ends of the second gas spring 42 are respectively hinged to the support arm 11 and the sliding seat 6 provided on the support arm 11 to be in parallel connection relative to the second telescopic driving member 32. Specifically, the two ends of the first gas spring 41 can be respectively connected to the two side surfaces of the mounting base 12 and the sliding seat 6 provided on the mounting base 12, and the two ends of the second gas spring 42 can be respectively connected to the two side surfaces of the support arm 11 and the sliding seat 6 provided on the support arm 11.

[0041] Among them, the first gas spring 41 and the second gas spring 42 should be arranged at a relatively small angle relative to the corresponding telescopic driving member 4. For example, the included angles α2 between the first gas spring 41 and the first telescopic driving member 31 and α1 between the second gas spring 42 and the second telescopic driving member 32 shown in the figure do not exceed 30°, so as to utilize the supporting effect of the gas spring 4 to offset the component force of the gravity of the tape reel 8 in the telescopic direction of the corresponding telescopic driving member 3.

[0042] A plurality of tape guiding rollers for guiding the released reinforcing tape to the core tube are usually mounted on the tape reel mounting bracket 7. In the present invention, at least some of the tape guiding rollers can be arranged behind the axial end of the support arm 11. Thus, the tape guiding rollers can stably guide the reinforcing tape and reduce the space occupied by the winding machine.

[0043] Referring to Figure 2 As shown, in the second preferred embodiment of the present invention, the tape reel mounting and adjusting mechanism has a structure substantially the same as that of the above first preferred embodiment. The following will mainly describe the differences therebetween.

[0044] Differently from the first preferred embodiment described above, the reel mounting adjustment mechanism uses a telescopic adjustment mechanism 33 to replace the connecting arm. The telescopic adjustment mechanism 33 is connected between the sliding seat 6 (mounted on the mounting base 12) and the reel mounting bracket 7, so as to be able to adjust the inclination angle of the reel 8 relative to the rotation axis of the winding machine by making the telescopic adjustment mechanism 33 extend and contract to different extension lengths. With this setting, since the extension and contraction of the telescopic adjustment mechanism 33 are directly converted into the change of the inclination angle of the reel 8, and the inclination angle of the telescopic adjustment mechanism 33 relative to the vertical direction increases as its extension length increases, it is thus allowed to adjust the inclination angle of the reel 8 within a large range. The winding machine can greatly adjust the winding angle and perform the winding of the reinforcing tape at different winding angles within a large range, having wide applicability.

[0045] One end of the telescopic adjustment mechanism 33 is hinged to the sliding seat 6 provided on the mounting base 12, and the reel mounting bracket 7 is respectively hinged to the telescopic adjustment mechanism 33 and the sliding seat 6 provided on the support arm 11 at spaced positions. Thus, when the first telescopic driving member 31 and the second telescopic driving member 32 extend and contract synchronously, the two sliding seats 6 are driven to drive the reel mounting bracket 7 and the reel 8 as a whole to move axially, realizing the adjustment of the axial position. When the second telescopic driving member 32 remains stationary and only the first telescopic driving member 31 is started to extend and contract, the reel mounting bracket 7 will flip with the hinge point with the sliding seat 6 provided on the support arm 11 as the center point, realizing the adjustment of the inclination angle (small-range adjustment). When both the first telescopic driving member 31 and the second telescopic driving member 32 remain stationary, the inclination angle can be adjusted (large-range adjustment) by only adjusting the extension length of the telescopic adjustment mechanism 33. Thus, the telescopic adjustment mechanism 33 can be set as an electric cylinder allowing on-line adjustment. During use, the inclination angle of the reel 8 can be adjusted on-line, and after the adjustment is basically in place, the first telescopic driving member 31 is used for fine adjustment. Alternatively, the telescopic adjustment mechanism 33 can also be set as a telescopically adjustable lead screw assembly, such as a plurality of adjusting rods connected by threads. The extension length is manually adjusted in the shutdown state to make the inclination angle of the reel 8 basically in place, and during the subsequent production process, the inclination angle of the reel 8 is adjusted on-line in a small range as needed by the first telescopic driving member 31. It can be understood that the telescopic adjustment mechanism 33 can also be other telescopic components or structures such as a hydraulic cylinder or a cylinder.

[0046] In this preferred embodiment, the gas springs 4 of the reel mounting adjustment mechanism include a first gas spring 41 and a second gas spring 42. Among them, the two ends of the first gas spring 41 are respectively hinged to the mounting base 12 and the reel mounting bracket 7 to be in parallel connection relative to the telescopic adjustment mechanism 33; the two ends of the second gas spring 42 are respectively hinged to the support arm 11 and the sliding seat 6 provided on the support arm 11 to be in parallel connection relative to the second telescopic driving member 32.

[0047] Among them, the first gas spring 41 and the second gas spring 42 should be arranged at a relatively small angle with respect to the corresponding telescopic driving member 4. For example, the included angle β between the first gas spring 41 and the telescopic adjustment mechanism 33 shown in the figure and the included angle α between the second gas spring 42 and the second telescopic driving member 32 do not exceed 30°, so as to utilize the supporting effect of the gas spring 4 to offset the component force of the gravity of the tape reel 8 in the telescopic direction of the corresponding telescopic driving member 3.

[0048] In a more preferred embodiment, two or more telescopic adjustment mechanisms 33 extending in parallel with each other may be connected between the tape reel mounting bracket 7 and the sliding seat 6 provided on the mounting base 12. This allows the tape reel 8 to load reinforced tapes with a higher weight, so as to increase the capacity of the tape reel 8 or the use of different types of reinforced tapes.

[0049] Refer to Figure 3 As shown, in the third preferred embodiment of the present utility model, the tape reel mounting and adjusting mechanism realizes the adjustment of the tilt angle of the tape reel by means of a handwheel screw adjustment method, and locks it at a predetermined tilt angle by using a mechanical locking structure, which significantly simplifies the structure and reduces the equipment cost. In this preferred embodiment, the tape reel mounting and adjusting mechanism includes a tape reel moving frame 2 slidably mounted on the rotating frame 1. Both ends of the telescopic driving member 3 are respectively connected to the rotating frame 1 and the tape reel moving frame 2, so as to be able to drive the tape reel moving frame 2 and the tape reel 8 mounted thereon to axially move on the rotating frame 1. Among them, both ends of the gas spring 4 are respectively connected to the rotating frame 1 and the tape reel moving frame 2, and are arranged in parallel relative to the telescopic driving member 3. Among them, the included angle α between the gas spring 4 and the telescopic direction of the telescopic driving member 3 (i.e., the axis of the winding machine) does not exceed 30°. Except for the telescopic driving member 3, other aspects of this preferred embodiment are the same as those of the Chinese utility model patent CN217947027U, and will not be elaborated here.

[0050] It can be understood that when the above-mentioned handwheel screw adjustment mechanism is replaced with an electric push rod and the mechanical locking structure is removed, a gas spring arranged in parallel with the electric push rod also needs to be connected between the tape reel moving frame 2 and the tape reel mounting bracket. By adopting the electric push rod method, the tilt angle of the tape reel can also be adjusted online without stopping the machine.

[0051] Refer to Figure 4 and Figure 5 As shown, the fourth and fifth preferred embodiments of the present utility model may have substantially the same structure. Specifically, the tape reel mounting and adjusting mechanism includes a tape reel moving frame 2. One of the tape reel moving frame 2 and the rotating frame 1 may be provided with an axial slide rail extending in a direction parallel to the rotation axis, and the other is provided with a sliding seat cooperating with the axial slide rail. Thus, power elements such as electric cylinders and hydraulic cylinders can be used to drive the tape reel moving frame 2 to axially slide on the rotating frame 1 to realize the adjustment of the axial position of the tape reel 8.

[0052] Among them, the tape reel 8 can be installed to be inclined relative to the rotation axis of the winding machine, that is, the rotation axis of the tape reel 8 when releasing the reinforcing tape is not perpendicular to the rotation axis, forming an inclined disk arrangement type winding machine. The tape reel installation adjustment mechanism serves as the installation foundation of the tape reel 8, and it can be used to adjust the inclination angle of the tape reel 8 relative to the rotation axis, so that the released reinforcing tape can be wound around the core tube at different helix angles. For this purpose, the tape reel installation adjustment mechanism of the present utility model includes a tape reel moving frame 2, a tape reel mounting frame 7 pivotally connected to the tape reel moving frame 2 through a pivot shaft and used for mounting the tape reel 8, and a telescopic driving member 3 whose two ends are respectively hinged to the tape reel moving frame 2 and the tape reel mounting frame 7, so as to be able to adjust the inclination angle of the tape reel 8 relative to the rotation axis of the winding machine by adjusting the telescopic length of the telescopic driving member 3. Among them, the telescopic driving member 3 can be an electric push rod, an electric cylinder or a hydraulic cylinder, etc.

[0053] The tape reel installation adjustment mechanism has an important influence on the installation and operation stability of the tape reel 8. In particular, when the reinforcing tape uses a relatively heavy steel strip or steel cord belt or the rotation speed of releasing the reinforcing tape is relatively fast, if the tape reel installation adjustment mechanism cannot stably support the tape reel 8 during the operation of the winding machine, it is easy to cause problems such as the tape reel being distorted or even falling off. For example, in order to arrange the driving unit for driving the tape reel 8 to rotate, the telescopic driving member 3 needs to be connected to the side of the tape reel mounting frame 7 that is offset relative to the rotation axis of the tape reel 8, thereby forming a support offset on the tape reel mounting frame 7, which is likely to cause the tape reel to be distorted or even fall off in the case of a heavy-duty tape reel.

[0054] For this purpose, in the tape reel installation adjustment mechanism of this preferred embodiment, the telescopic driving member 3 is arranged such that its central axis is coplanar with the rotation axis of the corresponding tape reel 8, and the plane determined by the central axis of the telescopic driving member 3 and the rotation axis of the corresponding tape reel 8 passes through the rotation axis or is parallel to the rotation axis. Among them, the central axis of the telescopic driving member 3 refers to the center line along its telescopic direction. For example, the straight line determined by the hinge points between the telescopic driving member 3 and the tape reel mounting frame 7 (specifically, the connecting seat 72 of the tape reel mounting frame 7) and between the telescopic driving member 3 and the tape reel moving frame 2 is the central axis of the telescopic driving member 3.

[0055] In the case where the rotation axis of the tape reel 8 is coplanar with the rotation axis of the winding machine (i.e., the rotation center line of the rotating frame 1), the plane determined by the central axis of the telescopic driving member 3 and the rotation axis of the corresponding tape reel 8 passes through the rotation axis; when the rotation axis of the tape reel 8 is not coplanar with the rotation axis of the winding machine, the rotation axis is parallel to the plane determined by the central axis of the telescopic driving member 3 and the rotation axis of the corresponding tape reel 8.

[0056] With the above settings, the supporting force exerted by the telescopic driving member 3 on the tape reel mounting bracket 7 lies in the central plane determined by the central axis of the telescopic driving member 3 and the rotation axis of the tape reel 8, which can avoid the generation of a supporting offset moment on the tape reel mounting bracket 7 and the tape reel 8 mounted thereon, and keep the force on the tape reel stable during the winding operation. In this case, the reel mounting and adjusting mechanism can be used in a winding machine with a heavy-duty tape reel, and problems such as tape reel distortion or even dropping caused by excessive offset moment can be avoided.

[0057] Generally, the tape reel 8 can be driven by a reduction motor 9 (such as a servo reduction motor) to rotate around its rotation axis. To avoid interference between the reduction motor 9 and the telescopic driving member 3, the reduction motor 9 can be connected to the rotating shaft of the tape reel 8 through a synchronous belt or gear drive to make room for connecting the telescopic driving member 3 on the tape reel mounting bracket 7. In a preferred embodiment of the present invention, the reduction motor 9 is arranged such that its power output end is coaxial with the tape reel 8, and the rotating shaft of the tape reel 8 is directly connected to the power output end of the reduction motor 9, for example, the rotating shaft of the tape reel 8 penetrates into the reduction motor 9. Through this direct connection method, the influence of the synchronous belt gap or gear gap in the synchronous belt or gear drive on the tape feeding synchronism and tension control accuracy can be avoided, thereby ensuring the winding quality. In this case, the arrangement and connection method of the telescopic driving member 3 and the tape reel mounting bracket 7 need to be appropriately set. For example, a receiving space is provided at a position aligned with the rotating shaft of the tape reel 8 by using the tape reel mounting bracket 7 or an intermediate connecting member, so that the reduction motor 9 is at least partially received in the receiving space.

[0058] In this preferred embodiment, the tape reel mounting bracket 7 includes a mounting bracket body 71 and a connecting seat 72 fixedly connected to the mounting bracket body 71. The tape reel 8 is rotatably mounted on the mounting bracket body 71, and one end of the electric push rod serving as the telescopic driving member 3 is hinged to the connecting seat 72. Among them, the connecting seat 72 forms a receiving space on the side of the mounting bracket body 71 facing the telescopic driving member 3 for at least partially receiving the reduction motor 9.

[0059] In Figure 4 In the shown preferred embodiment, one end of the telescopic driving member 3 is hinged to the tape reel moving bracket 2, and the other end is hinged to the connecting seat 72 of the tape reel mounting bracket 7. At the same time, a gas spring 4 is respectively hinged between the tape reel moving bracket 2 and the connecting seat 72 and is arranged in parallel with the telescopic driving member 3.
