Description

Technical Field

[0001] This utility model belongs to the field of plastic pipe forming technology, specifically relating to a wire-reinforced plastic composite pipe winding machine that maintains constant tension. Background Technology

[0002] To improve the mechanical properties of conveying pipelines, it is usually necessary to use a winding machine to wind filamentous reinforcing materials such as steel wire, polyester filament, and spun filament onto plastic pipes to form composite pipes.

[0003] Current winding machines only have the function of winding reinforcing wires onto pipes, but they cannot control the tension of the reinforcing wires to remain constant. During the unwinding process, the tension of the reinforcing wires will fluctuate due to the dynamic changes in the winding diameter, resulting in uneven bonding force between the winding layers. Utility Model Content

[0004] This invention addresses the aforementioned problems in the existing technology by proposing a wire-reinforced plastic composite tube winding machine that maintains constant tension.

[0005] This utility model can be achieved through the following technical solutions:

[0006] A filament-reinforced plastic composite tube winding machine that maintains constant tension includes:

[0007] Mounting bracket, which has a central hole for pipes to pass through;

[0008] The drive mechanism is mounted on the mounting bracket;

[0009] A yarn feeding mechanism includes a turntable and at least one set of yarn storage trays mounted on the turntable. The driving mechanism is linked to the turntable. As the turntable rotates, the yarn storage trays rotate synchronously and feed yarn.

[0010] A tension control mechanism, integrated into the yarn storage tray, is configured to dynamically compensate for changes in the winding diameter during the unwinding process of the reinforcing yarn via a bidirectional friction compensation mechanism, the bidirectional friction compensation mechanism including:

[0011] A constant torque component is applied axially to the wire storage disc, and the constant torque component increases the unwinding tension as the diameter of the reinforcing wire decreases;

[0012] The elastic friction component of the reinforcing filament is applied radially to the filament storage tray, and the elastic friction component reduces the unwinding tension as the reinforcing filament roll diameter decreases;

[0013] The superposition of the constant torque component and the elastic friction component ensures that the reinforcing filament maintains a constant tension throughout the entire unwinding process.

[0014] As a further improvement of this utility model, the tension control mechanism includes an axial elastic friction device, which includes a first spring. The first spring is sleeved on the mandrel of the wire storage disc and applies a constant pressure to the wire storage disc to form the constant torque component.

[0015] As a further improvement of this utility model, the tension control mechanism further includes a radial elastic clamping device, which comprises:

[0016] A pressure plate that contacts the surface of the reinforcing wire wound on the wire storage tray and provides friction;

[0017] A second spring, one end of which is fixed and the other end of which is connected to the pressure plate to provide radial clamping force;

[0018] The frictional force between the pressure plate and the reinforcing wire is dynamically adjusted according to the change in the diameter of the reinforcing wire roll, forming the elastic friction component.

[0019] As a further improvement of this utility model, a set of the wire storage trays is composed of multiple individual wire storage trays. Multiple sets of wire storage trays are evenly distributed along the central circumference on one side of the turntable. The multiple sets of wire storage trays can be arranged in circles, and the centers of the inner and outer circles of wire storage trays are staggered.

[0020] As a further improvement of this utility model, the mounting frame is provided with the wire feeding mechanism on the front and rear sides respectively and is divided into a front wire feeding mechanism and a rear wire feeding mechanism. The driving mechanism is simultaneously linked to the two turntables. The driving mechanism drives the two turntables to rotate simultaneously, and at this time, each of the wire storage trays on one side of the two turntables performs the wire feeding action.

[0021] As a further improvement of this utility model, the front wire feeding mechanism and the rear wire feeding mechanism are respectively provided with transition wire rings, and the reinforcing wires on each of the wire storage trays are led outward through the transition wire rings.

[0022] As a further improvement of this utility model, the front end of the wire feeding mechanism is also provided with at least one wire splitting ring and a wire guide ring. The reinforcing wires output from each of the wire storage discs pass through the wire splitting ring and the wire guide ring in sequence and are then pulled to the surface of the pipe.

[0023] As a further improvement of this utility model, the inner ring of the turntable is also equipped with a wire feeding tube, wherein each of the wire storage discs on the rear wire feeding mechanism is led out through its respective transition wire ring and then passes through the wire feeding tube and is pulled to the wire separating ring.

[0024] As a further improvement of this utility model, the front end of the guide ring is further provided with a wire locking mechanism, the wire locking mechanism comprising:

[0025] A locking ring seat has a mounting base at its bottom, and the locking ring seat can move back and forth on the mounting base to adjust its position.

[0026] A locking ring is installed on the locking ring seat. The pipe passes through the locking ring, and the reinforcing wires led out from the guide ring are pulled into the space formed by the outer diameter of the pipe and the inner hole of the locking ring, so that the reinforcing wires are pressed tightly against the outer wall of the pipe and evenly distributed.

[0027] As a further improvement of this utility model, the driving mechanism includes:

[0028] A drive motor is mounted on the mounting bracket, which has two mounting plates;

[0029] A gear bearing structure that is connected to both the turntable and the mounting plate;

[0030] A transition shaft is connected to the drive motor via a sprocket. Both ends of the transition shaft pass through two mounting plates and are equipped with drive gears. The two drive gears mesh with the external teeth of the gear bearing structure of the front wire feeding mechanism and the rear wire feeding mechanism, respectively.

[0031] The drive motor drives the transition shaft and the drive gear to rotate. The drive gear drives the turntable to rotate through the gear bearing structure. At this time, the wire storage trays set on one side of the two turntables rotate and release wire synchronously. As the tube continues to move forward and the left and right winding devices are configured, the two adjacent layers of reinforcing wires are intersected and pressed tightly onto the tube.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1. By integrating a bidirectional friction compensation tension control mechanism, and combining the superposition of the axial constant torque component and the radial elastic friction component, the tension of the reinforcing wire is kept constant throughout the unwinding process, effectively avoiding tension fluctuations caused by changes in the roll diameter, thereby preventing defects such as interlayer peeling, and significantly improving the forming quality and product consistency of the composite tube.

[0034] 2. The front and rear wire feeding mechanisms are symmetrically arranged on the front and rear sides of the mounting frame, which makes the overall load of the equipment balanced, reduces vibration and noise, and improves operational stability. At the same time, the reasonable structural layout reduces the center height of the equipment, eliminates the need for pit installation, has strong adaptability, and reduces manufacturing costs and installation difficulty.

[0035] 3. The reinforcing wires drawn from each wire storage disc are uniformly dispersed by the wire distribution ring, then guided by the wire guide ring, and finally wound on the surface of the pipe in a specific direction and at a specific interval to form a reinforcing layer with a specific shape layout.

[0036] 4. The wire feeding tube is designed to gather and guide the multiple reinforcing wires (or strands) drawn from the rear wire feeding mechanism, so that they can be pulled onto the wire splitting ring along a specific path, ensuring that they will not interfere with the reinforcing wires drawn from the front wire feeding mechanism, thereby improving the reliability and stability of the wire feeding process.

[0037] 5. The reinforcing wires, which are pressed and evenly distributed by the locking ring, are spirally wound on the outer wall of the pipe. The left and right spiral winding devices are configured to form a reinforcing wire mesh layer covering the surface of the pipe. By changing the locking ring and adjusting the front and rear positions of the locking ring seat, the device can be adapted to the winding of pipes with different outer diameters, thereby improving the versatility and adaptability of the winding device.

[0047] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. The technical methods of the present invention will be further described, but the present invention is not limited to these embodiments.

[0048] like Figures 1-4 As shown, a filament-reinforced plastic composite tube winding machine that maintains constant tension includes:

[0049] Mounting bracket 100 has a central hole through which pipe 500 passes;

[0050] The drive mechanism 200 is mounted on the mounting bracket 100;

[0051] The wire feeding mechanism includes a turntable 320 and at least one set of wire storage trays 330 mounted on the turntable 320. The drive mechanism 200 is linked to the turntable 320. As the turntable 320 rotates, the wire storage trays 330 rotate synchronously and feed the wire. During this process, as the tube 500 is linearly conveyed and the wire storage trays 330 rotate and feed the wire, the reinforcing wire (such as steel wire, polyester wire, spun yarn, etc.) is wound onto the surface of the tube 500 at a preset winding angle.

[0052] Tension control mechanism 400, integrated into yarn storage tray 330, is configured to dynamically compensate for changes in winding diameter during the unwinding process of reinforcing yarn through a bidirectional friction compensation mechanism. The bidirectional friction compensation mechanism includes:

[0053] A constant torque component is applied axially to the wire storage disc 330, and the constant torque component increases the unwinding tension as the diameter of the reinforcing wire decreases;

[0054] The elastic friction component of the reinforcing filament is applied radially to the filament storage disc 330. The elastic friction component reduces the unwinding tension as the reinforcing filament roll diameter decreases.

[0055] The superposition of the constant torque component and the elastic friction component enables the reinforcing filament to maintain a constant tension throughout the entire unwinding process.

[0056] It is through the bidirectional friction compensation mechanism that the reinforcing yarn can maintain constant tension throughout the unwinding process, fundamentally solving the problem of interlayer peeling caused by uneven tension. Furthermore, this bidirectional friction compensation mechanism can automatically adjust the tension output according to the change in roll diameter, without the need for manual intervention or complex electronic control systems.

[0057] The following is a detailed description of the tension control mechanism 400:

[0058] Preferably, the tension control mechanism 400 includes an axial elastic friction device 410, which includes a first spring 411. The first spring 411 is sleeved on the spindle of the wire storage disc 330. One end of the first spring 411 abuts against the axial outer end face of the wire storage disc 330, and the other end abuts against a nut fixed on the spindle of the wire storage disc 330, thereby applying a constant pressure to the wire storage disc 330 to form a constant torque component.

[0059] It should be noted that when a constant torque component is applied to the wire storage tray 330 through the first spring 411, during the wire feeding process, as the diameter of the reinforcing wire on the wire storage tray 330 gradually decreases, although the applied torque remains unchanged, the lever arm (i.e., the distance from the center of rotation to the point where the reinforcing wire is pulled out) also decreases, resulting in a gradual increase in the pulling force of the reinforcing wire (i.e., the tension of the reinforcing wire).

[0060] Based on this, in order to control the tension of the reinforcing filament to remain constant during the unwinding process, a radial elastic friction component is correspondingly added to counteract the increase in tension from the constant torque component filament. This elastic friction component is provided by a radial elastic clamp 420. Specifically, the radial elastic clamp 420 includes:

[0061] The pressure plate 421 contacts the surface of the reinforcing wire wound on the wire storage tray 330 and provides friction to generate another torque for the rotation of the wire storage tray 330.

[0062] The second spring 422 is fixed at one end and connected to the pressure plate 421 at the other end to provide radial clamping force.

[0063] The working principle of the radial elastic clamp 420 is as follows: During the wire feeding process, as the diameter of the reinforcing wire roll on the wire storage tray 330 decreases, the compression of the second spring 422 decreases. At this time, the positive pressure of the pressure plate 421 on the reinforcing wire gradually decreases, and correspondingly, the pulling force of the reinforcing wire (i.e., the tension of the reinforcing wire) gradually decreases. Therefore, the friction between the pressure plate 421 and the reinforcing wire is dynamically adjusted with the change of the roll diameter, forming the required elastic friction component.

[0064] In other words, the axial elastic friction device 410 causes the tension of the reinforcing filament to increase naturally as the roll diameter decreases, while the radial elastic clamp 420 compensates by reducing the tension, ensuring that the tension of the reinforcing filament remains constant regardless of the roll diameter.

[0065] Therefore, by precisely setting the elastic parameters and pre-compression amount of the first spring 411 and the second spring 422, the tension of the reinforcing wire can be kept constant during the unwinding process. This bidirectional friction compensation mechanism not only solves the tension fluctuation problem commonly found in traditional winding equipment, but also significantly improves the quality and production efficiency of composite tubes.

[0066] Preferably, a set of wire storage trays 330 consists of multiple individual wire storage trays 330. Multiple sets of wire storage trays 330 can be evenly distributed along the central circumference on one side of the turntable 320. The multiple sets of wire storage trays 330 can be arranged in circles, and the centers of the inner and outer circles of wire storage trays 330 are staggered.

[0067] This staggered arrangement of rings effectively improves the space utilization of the turntable 320, reduces structural interference and wire feeding interference caused by the concentrated arrangement of the wire storage tray 330, and optimizes the winding path, making the reinforcing wire more evenly distributed when wound onto the surface of the tube 500, avoiding the phenomenon of wire overlap or uneven gaps.

[0068] Preferably, the mounting frame 100 is provided with a wire feeding mechanism on the front and rear sides to form a front wire feeding mechanism 300 and a rear wire feeding mechanism 310. The drive mechanism 200 is simultaneously linked to the two turntables 320. The drive mechanism 200 drives the two turntables 320 to rotate simultaneously. At this time, each wire storage plate 330 on one side of the two turntables 320 performs a wire feeding action.

[0069] It is worth mentioning that, because the front wire feeding mechanism 300 and the rear wire feeding mechanism 310 are respectively set on the front and rear sides of the mounting frame 100, the load on both sides of the transmission mechanism is relatively evenly distributed, the operation is stable and the structure is compact, the manufacturing cost is low, the center height of the winding machine is reduced, there is no need to dig a pit for installation, and it is highly adaptable to the production workshop.

[0070] Overall, this winding machine achieves stable operation and rational space utilization through a symmetrically arranged wire feeding mechanism. By integrating a bidirectional friction-compensated tension control mechanism 400, it effectively solves the tension fluctuation problem caused by changes in roll diameter in the prior art, significantly improving the winding quality of reinforcing wire and the overall performance of the composite tube. Compared with the prior art, this utility model has obvious advantages in terms of structural design, tension control accuracy, product quality consistency, and equipment operation stability.

[0071] Preferably, the drive mechanism 200 includes:

[0072] A drive motor 210 is mounted on a mounting bracket 100, which has two mounting plates 110.

[0073] The gear bearing structure 220 is connected to both the turntable 320 and the mounting plate 110.

[0074] The transition shaft 230 is connected to the drive motor 210 via a sprocket 240. The two ends of the transition shaft 230 pass through two mounting plates 110 and are equipped with drive gears 250. The two drive gears 250 mesh with the external teeth of the gear bearing structure 220 of the front wire feeding mechanism 300 and the rear wire feeding mechanism 310, respectively.

[0075] The drive motor 210 drives the transition shaft 230 and drive gear 250 to rotate. The drive gear 250 drives the turntable 320 to rotate through the gear bearing structure 220. At this time, the wire storage disc 330 set on one side of the two turntables 320 synchronously performs the wire feeding action. As the tube 500 continues to move forward and the left and right spiral winding devices are configured, the two adjacent layers of reinforcing wires can be interlocked and tightly wound on the tube 500.

[0076] Preferably, the gear bearing structure 220 includes an inner ring gear bearing 221 and an outer ring gear bearing 222. The inner ring gear bearing 221 is mounted on the mounting plate 110, and the outer ring gear bearing 222 is mounted on the turntable 320. Specifically, the tooth surface of the outer ring gear bearing 222 meshes with the drive gear 250. As the drive motor 210 drives the transition shaft 230 to rotate, the drive gears 250 at both ends of the transition shaft 230 can drive the outer ring gear bearing 222 to rotate. At this time, the turntable 320 rotates accordingly and realizes the rotation and wire feeding action of the wire storage tray 330. The inner ring gear bearing 221 is connected to the mounting bracket 100 and is always in a fixed state.

[0077] Through the cooperation of the drive mechanism 200 and the gear bearing structure 220, the front wire feeding mechanism 300 and the rear wire feeding mechanism 310 can feed wire synchronously. As the tube 500 moves forward, the reinforcing wire is spirally wound on the outer wall of the tube 500.

[0078] Preferably, the front wire feeding mechanism 300 and the rear wire feeding mechanism 310 are also provided with transition wire rings 340 respectively. The reinforcing wires on each wire storage plate 330 are led out through separate transition wire rings 340, so that the reinforcing wires led out from each wire storage plate 330 are led out independently and will not interfere with each other.

[0079] Preferably, the front end of the wire feeding mechanism 300 is further provided with at least one wire distribution ring 350 and a wire guide ring 360. The reinforcing wires output from each wire storage disc 330 are sequentially drawn to the surface of the pipe 500 after passing through the wire distribution ring 350 and the wire guide ring 360. The reinforcing wires drawn from each wire storage disc 330 are uniformly dispersed by the wire distribution ring 350, then drawn and guided by the wire guide ring 360, and finally wound on the surface of the pipe 500 in a specific direction and at a specific spacing to form a reinforcing layer with a specific shape layout.

[0080] Preferably, the inner ring of the turntable 320 is also equipped with a wire guide tube 370. Each wire storage disc 330 on the rear wire feeding mechanism 310 is led out through its respective transition wire ring 340 and passes through the wire guide tube 370 and is pulled to the wire distribution ring 350. The wire guide tube 370 plays a role in gathering and guiding the multiple (or strands) of reinforcing wires led out from the rear wire feeding mechanism 310, so that they can be pulled to the wire distribution ring 350 along a specific path, ensuring that there is no interference with the reinforcing wires led out from the front wire feeding mechanism 300, thereby improving the reliability and stability of the wire feeding process.

[0081] Preferably, the front end of the guide ring 360 is further provided with a wire locking mechanism 380, which includes:

[0082] The locking ring seat 381 has a mounting base 382 at its bottom, and the locking ring seat 381 can move back and forth on the mounting base 382 to adjust its position.

[0083] The locking ring 383 is installed on the locking ring seat 381. The pipe 500 passes through the locking ring 383. The reinforcing wires led out from the guide ring 360 are pulled into the space formed by the outer diameter of the pipe 500 and the inner hole of the locking ring 383, so that the reinforcing wires are pressed tightly against the outer wall of the pipe 500 and evenly distributed.

[0084] Specifically, the reinforcing wires, which are pressed and evenly distributed by the locking ring 383, are spirally wound on the outer wall of the pipe 500. Through the configuration of left and right spiral winding devices, a composite reinforcing layer of reinforcing wire mesh covering the surface of the pipe 500 is formed. By replacing the locking ring 383 and adjusting the front and rear positions of the locking ring seat 381, the device can be adapted to winding pipes 500 with different outer diameters, thereby improving the versatility and adaptability of the winding device.
