Description

Technical Field

[0001] This invention relates to composite pipe production equipment, specifically to a winding machine. Background Technology

[0002] To improve the mechanical properties of conveying pipelines, it is usually necessary to use a winding machine to wind reinforcing materials such as steel strips and fiber strips onto a plastic core tube to form a composite pipe. The winding machine mainly consists of a fixed frame and a turntable mechanism (rotating support) pivotally connected to it. As the plastic core tube is conveyed forward along the rotation axis of the turntable mechanism, the turntable mechanism drives the reel on it to rotate and release the reinforcing strip on the reel, thereby winding the reinforcing strip onto the plastic core tube.

[0003] The rotating support of existing winding machines typically consists of a front plate, a rear support frame, and multiple support arms connecting the front plate and the rear support frame. While this configuration forms a frame structure, it places very high demands on the machining and assembly processes of the front plate, rear support frame, and support arm mounting surfaces. This can easily lead to misalignment of the frame, causing the winding machine to vibrate or shake during rotation. Furthermore, the weight of the tape unloading unit, coupled with the fully loaded reinforcing tape, is considerable. Over long-term operation, this can also cause deformation of the rotating support due to the load, thus affecting the quality of pipe production.

[0004] For example, Chinese Patent Application No. 201920741563.4 discloses a winding machine. This machine includes a rotating support, which is rotatably connected to a fixed frame and includes a front end plate, multiple support arms, and a rear support frame connected to the tail ends of each support arm. Some support arms are equipped with reels, allowing the reinforcing tape on the reels to be wound onto a core tube that passes through the rotating support and extends along the rotation axis during the rotation of the rotating support. In this case, the rotating support lacks sufficient rigidity, which can easily cause deformation of the rotating support frame, thus affecting the winding quality of the composite pipe.

[0005] In the aforementioned prior art, both axial adjustment and tilt adjustment of the pulley are achieved by moving an electric push rod parallel to the central axis of the pipe. However, during production, it was found that once the tilt adjustment is set during startup and commissioning, it does not need to be adjusted during formal production. In production, the winding spacing can be adjusted simply by moving the pulley back and forth.

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

Detailed Implementation

[0027] The specific embodiments of the present invention 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 present invention.

[0028] In this invention, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the orientation shown in the accompanying drawings, and "inner" and "outer" refer to the inner and outer sides relative to the outline of each component itself.

[0029] like Figure 1 and Figure 2As shown, the present invention provides a winding machine including a winding machine base 1; a winding machine housing 2, the winding machine housing 2 being mounted above the winding machine base 1; a central rotating frame 30, the central rotating frame 30 being rotatably connected to the winding machine housing 2 and including a rear end plate 31, a plurality of side plates 32 extending from the rear end plate 31 in a direction parallel to the rotation axis, and a front end plate 34 mounted on the side plate 32 away from the rear end plate 31, adjacent side plates 32 being connected to each other to form a housing structure around the rotation axis; and a plurality of tape feeding units 50, each of the tape feeding units 50 being respectively mounted to the side plate 32 and including a tape reel bracket 52 for mounting a tape reel 51, the tape reel bracket 52 being configured to allow the reinforcing tape on the tape reel 51 to be wound onto a core tube that passes through the central rotating frame 30 and extends along the rotation axis during the rotation of the central rotating frame 30. It can be understood that each side plate 32 corresponds to a set of tape feeding units 50, and the number of tape feeding units 50 is equal to the number of side plates 32.

[0030] In one embodiment, in order to reduce the amount of processing and production cost of the side plate 32, multiple mounting plates 33 extending along the rotation axis can be provided at intervals on the outer surface of the side plate 32. The mounting plates 33 are provided with mounting surfaces, and each of the tape feeding units 50 is respectively mounted on the mounting surface.

[0031] In this invention, the central rotating frame 30 is configured as a box-shaped frame structure composed of a rear end plate 31, a side plate 32, and a front end plate 34. This box-shaped frame structure increases the moment of inertia of the central rotating frame 30, giving it good mechanical properties, thereby improving its stiffness and stability. Furthermore, the central rotating frame 30 has a simple manufacturing process, a robust structure, and can withstand large loads. It is understood that the rear end plate 31, side plate 32, and front end plate 34 can be welded together to form the central rotating frame 30. Preferably, the rear end plate 31 is an annular structure with multiple mounting holes, through which the central rotating frame 30 is rotatably connected to the winding machine housing 2.

[0032] Specifically, such as Figure 5 As shown, the central rotating frame 30 is provided with a plurality of stiffeners 35 for reinforcing the side plates 32. In one embodiment, the stiffeners 35 include a first stiffener connecting two adjacent side plates 32, a second stiffener connecting two adjacent first stiffeners, and a third stiffener connecting the rear end plate 31 with the side plates 32 or the first stiffeners. The third stiffener may be configured to be inclined toward the side plates 32 in the direction from the front end plate 34 toward the rear end plate 31.

[0033] In one embodiment of the present invention, the edges of a plurality of side plates 32 parallel to the axis of rotation are sequentially connected to form a cross section whose projection is a polygon, wherein the polygon is a regular polygon. The number of side plates 32 is determined by the number of tape feeding units 50, for example, there can be 3, 4, 5, 6, etc.

[0034] Reference Figure 2 , Figure 4 and Figure 7 The winding machine includes a rotary support 6 installed between the winding machine housing 2 and the central rotating frame 30. The inner ring of the rotary support 6 is fixedly installed on the outer surface of the winding machine housing 2. A motor 7 and a reducer 80 electrically connected to the motor 7 are disposed inside the winding machine housing 2. The output shaft of the reducer 80 extends in a direction parallel to the rotation axis. A drive pinion 81 is installed on the output shaft of the reducer 80, and the drive pinion 81 meshes with the outer ring of the rotary support 6. The rear end plate 31 is installed on the outer surface of the outer ring so that the central rotating frame 30 and the rotary support 6 rotate together. The rotary support 6 is a large bearing capable of withstanding combined loads, simultaneously bearing large axial and radial loads and overturning moments, and providing good rotational stability.

[0035] Because the tape feeding unit 50 mounted on the slewing support 6 has a large mass, it will continue to rotate under inertial force when the motor 7 stops working, which may lead to production accidents and damage to the motor 7. In this invention, a brake disc 15 is provided between the slewing support 6 and the central rotating frame 30. The brake disc 15 can decelerate or stop the slewing support 6. When the motor 7 stops working, the brake disc 15 receives a braking signal, enabling the slewing support 6 to quickly brake and stop rotating, thereby reducing the occurrence of production accidents.

[0036] Furthermore, such as Figure 4 As shown, a tape feeding motor 53 is mounted on the tape reel bracket 52, and the tape reel 51 is drivenly connected to the output end of the tape feeding motor 53. In one embodiment, the tape reel 51 can be connected to the output end of the tape feeding motor 53 via a transmission belt.

[0037] like Figure 1 As shown, in one embodiment, the tape unloading unit 50 includes a tension guide roller group 54 and a heating device 55 mounted on the tape reel support 52. The reinforcing tape is released from the tape reel 51, tensioned by the tension guide roller group 54, heated by the heating device 55, and wound onto the outside of the core tube.

[0038] In a preferred embodiment of the present invention, the winding machine may further include a tube stabilizing device 13 installed on the outside of the front end plate 34. Specifically, the tube stabilizing device 13 may be installed on the side of the front end plate 34 away from the rear end plate 31. In addition, an electrical control box 14 is installed on the outside of the side plate 32 or the mounting plate 33. In one embodiment, a set of tape feeding units 50 is equipped with an electrical control box 14, a set of tension guide rollers 54, and a heating device 55. The electrical control box 14 is used to control the start and stop of the tape feeding motor 53, its speed, and the start and stop of the heating device 55.

[0039] like Figure 3 and Figure 6 As shown, in this invention, the tape feeding unit 50 is mounted on the side plate 32 via a tape reel tilt adjustment mechanism 40. The tape reel tilt adjustment mechanism 40 includes a mechanism support assembly 41, an upper adjustment mechanism 42 and a lower adjustment mechanism 43 respectively mounted on the mechanism support assembly 41. The edge of the tape reel support 52 is hinged to the mechanism support assembly 41 via a first rotating shaft 9. The upper adjustment mechanism 42 allows the tape reel support 52 to rotate around the first rotating shaft 9, and the lower adjustment mechanism 43 allows the tape reel support 52 to move horizontally relative to the central rotating frame 30. In one embodiment, the tape feeding unit 50 is mounted on the mounting surface of the mounting plate 33 via the tape reel tilt adjustment mechanism 40.

[0040] Specifically, such as Figure 8 and Figure 9 As shown, the mechanism support assembly 41 includes an upper mounting plate 411 and a lower mounting plate 412 arranged parallel and spaced apart, and a vertical plate 413 connected to the upper mounting plate 411 and the lower mounting plate 412. The disc bracket 52 is hinged to the vertical plate 413. In one embodiment, the mechanism support assembly 41 includes vertical plates 413 located on both sides of the upper mounting plate 411 and the lower mounting plate 412 and extending vertically. The vertical plates 413 have protrusions extending from the upper surface of the upper mounting plate 411, and the protrusions have through holes for the first rotating shaft 9 to pass through.

[0041] Further, the lower adjustment mechanism 43 includes a telescopic drive member 431 and a first slider 432 mounted on the side plate 32, a movable connecting seat 433 and a first slide rail 434 mounted on the bottom surface of the lower mounting plate 412. The first slide rail 434 is slidably connected to the first slider 432. The output end of the telescopic drive member 431 is connected to the movable connecting seat 433. The telescopic drive member 431 extends and retracts to allow the mechanism support assembly 41 to move horizontally relative to the central rotating frame 30. In one embodiment, the telescopic drive member 431 is mounted on the outer surface of the side plate 32, and the first slider 432 is mounted on the mounting surface of the mounting plate 33. Preferably, the telescopic drive member 431 is an electric push rod. In this invention, the lower adjustment mechanism 43 allows the mechanism support assembly 41 to move horizontally relative to the central rotating frame 30, thereby allowing the reel support 52 and the reel 51 to move horizontally relative to the central rotating frame 30. By adjusting the reel 51 to different horizontal positions, the winding spacing of the reinforcing belt on the core tube is changed. In one embodiment, in order to improve the stability of the winding machine during operation, the lower adjustment mechanism 43 may include a plurality of first slide rails 434 mounted on the bottom surface of the lower mounting plate 412, and each first slide rail 434 may be equipped with a plurality of first sliders 432.

[0042] Furthermore, such as Figure 6 As shown, the winding machine includes an angle adjustment arm 10. The first end of the angle adjustment arm 10 is rotatably connected to the reel support 52 via a second rotating shaft 11, and the second end of the angle adjustment arm 10 is rotatably connected to the upper adjustment mechanism 42 via a third rotating shaft 12. The winding machine may include two angle adjustment arms 10 respectively mounted on both sides of the reel support 52. It is understood that the reel support 52 has a through hole for the second rotating shaft 11 to pass through, and the through hole may be formed near the center of the side plate of the reel support 52.

[0043] Furthermore, the upper adjustment mechanism 42 includes a lead screw 421 extending along the rotation axis, a lead screw nut 422 screwed to the lead screw 421, a second slide rail 423 mounted on the upper mounting plate 411, and a slide block assembly 424 movably connected to the second slide rail 423. The lead screw nut 422 is connected to the bottom of the slide block assembly 424, and the second end is connected to the slide block assembly 424. The lead screw 421 rotates so that the second end moves in a direction parallel to the rotation axis. The mechanism support assembly 41 and the reel support 52 are hinged together by a first pivot 9; the first end of the tilt adjustment arm 10 is hinged to the reel support 52 by a second pivot 11; and the second end of the tilt adjustment arm 10 is hinged to the slide assembly 424 by a third pivot 13. The slide assembly 424 can move horizontally relative to the mechanism support assembly 41. This movement of the slide assembly 424 changes the position of the second end of the tilt adjustment arm 10, allowing the reel support 52 to rotate around the first pivot 9, thereby changing the tilt angle of the reel support 52 and further altering the winding angle of the reinforcing belt on the core tube. Furthermore, to facilitate the adjustment of the tilt angle of the reel support 52, bearings can be respectively provided between the first pivot 9 and the upright plate 413, between the second pivot 11 and the reel support 52, and between the third pivot 12 and the slide assembly 424.

[0044] like Figure 3 As shown, to facilitate adjustment of the position of the slide assembly 424, the upper adjustment mechanism 42 includes a steering mechanism 425. The steering mechanism 425 includes a handwheel 4251, a handwheel shaft 4252, and a first bevel gear 4253 and a second bevel gear 4254 that mesh perpendicularly with each other. The second bevel gear 4254 is coaxially connected to the lead screw 421, and the handwheel 4251 is coaxially connected to the first bevel gear 4253 through the handwheel shaft 4252. Rotating the handwheel 4251 causes the lead screw 421 to rotate. Furthermore, the mechanism support assembly 41 is also provided with a lead screw end seat 426, and the end of the lead screw 421 away from the steering mechanism 425 is connected to the lead screw end seat 426.

[0045] Furthermore, the slide assembly 424 includes a second slider 4241 movably connected to the second slide rail 423 and a slide block 4242 mounted on top of the second slider 4241. A cylindrical portion for the third rotating shaft 12 to pass through is formed on the upper part of the slide block 4242. The length of the cylindrical portion may be equal to or close to the width of the disc support 52.

[0046] In one embodiment, to improve the stability of the winding machine during operation, the upper adjustment mechanism 42 may include two second slide rails 423 mounted on the top surface of the upper mounting plate 411. Each second slide rail 423 may have a corresponding second slider 4241 mounted on it, and the slide block 4242 connects the two second sliders 4241 to move together. Furthermore, the winding machine may include two tilt adjustment arms 10, which are respectively mounted at both ends of the cylindrical portion. The third rotating shaft 12 passes through the tilt adjustment arms 10 and the cylindrical portion in sequence, thereby connecting the tilt adjustment arms 10 to the slide block assembly 424. Further, the lead screw nut 422 can be connected to the bottom of the slide block assembly 424 in any way, such as by fasteners or welding. To reduce the number of parts used and simplify the connection between parts, in one embodiment, a groove is formed at the bottom of the slide block 4242, and the lead screw nut 422 is engaged in the groove.

[0047] In a preferred embodiment of the present invention, the reel tilt adjustment mechanism 40 includes a fastening handle 44 and a locking block 45 connected to the side of the slide 4242. The locking block 45 has a threaded hole, and the fastening handle 44 is screwed into this threaded hole and abuts against the side of the upright plate 413 to restrict the movement of the slide assembly 424. The lower surface of the locking block 45 extends below the top surface of the upright plate 413, and the fastening handle 44 restricts the movement of the slide assembly 424 through friction generated between itself and the upright plate 413. Furthermore, in one embodiment, a graduated marking may be affixed to the upright plate 413, and the locking block 45 has a pointer-like structure; the tilt angle of the reel support 52 is determined by the graduation indicated by this pointer.

[0048] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the inventive concept, various simple modifications can be made to the technical solutions of the present invention, including combinations of various specific technical features in any suitable manner. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
