Description

Technical Field

[0001] This utility model belongs to the field of PET plastic steel tape production technology, specifically relating to a PET plastic steel tape winding machine. Background Technology

[0002] PET strapping, also known as plastic strapping, is a packaging material made primarily from polyethylene terephthalate (PET). During production, the finished PET strapping needs to be wound onto empty rolls for storage and transportation; this process is typically completed by specialized winding equipment.

[0003] When the roll on the winding machine reaches full capacity, it must be replaced with a new empty roll in a timely manner to ensure the continuity of the winding operation. However, in actual production, the operating speed of the production line may fluctuate, such as acceleration, deceleration, or temporary shutdown. Existing winding equipment often cannot adapt to such speed changes in real time, which can easily lead to the PET plastic strapping being torn or loosened during the winding process, affecting product quality and production efficiency. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention utilizes a winding mechanism to wrap PET plastic steel tape around a paper tube, while a guiding mechanism simultaneously drives the PET plastic steel tape to spirally reciprocate around the paper tube surface. During production, the PET plastic steel tape first enters a tensioning device for tension adjustment, and then enters the winding mechanism. Specifically, after entering the tensioning device, the PET plastic steel tape is guided by a guide roller assembly and a second guide wheel on the second moving platform. Since the second optical axis is vertically positioned, the second moving platform naturally droops under gravity. When the speed of the PET plastic steel tape on the production line fluctuates, its tension changes accordingly: when the tape is taut, the second moving platform is moved upwards; when the tape is loose, the second moving platform falls under gravity. The up-and-down movement of the second moving platform drives an encoder via belt transmission. The controller obtains real-time information on production line speed fluctuations based on the encoder's feedback signal and dynamically adjusts the winding speed of the winding mechanism, effectively preventing the PET plastic steel tape from breaking or becoming loose during winding, thus improving product quality and production efficiency.

The driven mechanism 22 includes a second support 27 and a second fixed drum assembly 28. The second support 27 is movably mounted on the second fixed drum assembly 28 via a second bearing seat 29. The first frame 3 is fixedly mounted with a first guide rail 30, a second guide rail 31, a first cylinder 32, and a third servo motor 33. The first guide rail 30 is movably connected to the active mechanism 21 via a third moving platform 34. The drive end of the first cylinder 32 is fixedly connected to the third moving platform 34.

The first support plate 37 has an adjustment groove 38, and a limit sensor 39 is fixedly mounted on the adjustment groove 38. The first fixed cylinder assembly 24 and the second fixed cylinder assembly 28 are identical mechanisms, each including a rotating shaft 40, a fixed plate 41, and a pressing plate 42. Both the fixed plate 41 and the pressing plate 42 have inclined surfaces 43, and a ring spring 44 is arranged between the two inclined surfaces 43.

[0024] Through the above technical solution, this utility model uses a winding mechanism 6 to wind PET plastic steel strip onto a paper tube, while a guiding mechanism 7 drives the PET plastic steel strip to reciprocate in a spiral manner around the surface of the paper tube. During production, the PET plastic steel strip first enters the tensioning device 4 for tension adjustment, and then enters the winding mechanism 6. Specifically, after entering the tensioning device 4, the PET plastic steel strip is guided by the guide roller shaft group 17 and the second guide wheel 22 on the second moving table 20. Since the second optical shaft 18 is vertically set, the second moving table 20 naturally droops under gravity. When the speed of the PET plastic steel strip on the production line fluctuates, its tension changes accordingly: when the strip is taut, the second moving table 20 is moved upwards; when the strip is loose, the second moving table 20 falls under gravity. The up-and-down movement of the second moving table 20 drives the encoder 19 to operate via the belt 21. The controller obtains the speed fluctuation information of the production line in real time based on the feedback signal of the encoder 19 and dynamically adjusts the winding speed of the winding mechanism 6, thereby effectively preventing the PET plastic steel belt from being pulled apart or becoming tangled and loose during the winding process, thus improving product quality and production efficiency.

[0025] Example 2:

[0026] The PET plastic strip winding machine of this embodiment includes a winding machine body 1 and a tensioning device 2. The winding machine body 1 consists of a first frame 3, a winding mechanism 4, and a guiding mechanism 5. The first frame 3 is fixedly mounted with the guiding mechanism 5 via a first moving device 6. The guiding mechanism 5 includes a fixed frame 7, a first servo motor 8, and a first moving table 9. The first moving table 9 is movably mounted with a first guide wheel 10, and the fixed frame 7 is movably mounted with a pressure roller shaft 11. The drive end of the first servo motor 8 is connected to the first moving table 9 via a first lead screw 12, and the fixed frame 7 is movably mounted with the first moving table 9 via a first optical shaft 13. The tensioning device 2 includes a second frame 14, and the second frame 14 is fixedly mounted with a guide roller shaft group 15, a second optical shaft 16, and an encoder 17. The second optical shaft 16 is movably mounted with a second moving table 18, which is connected to the encoder 17 via a belt 19. The second moving table 18 is movably mounted with a second guide wheel 20.

[0027] During the winding process, the PET plastic strip first enters the tensioning device 2 for tension adjustment. In the tensioning device 2, the PET plastic strip is guided by the guide roller shaft group 15 and the second guide wheel 20 on the second moving table 18. The second optical shaft 16 is vertically set, and the second moving table 18 hangs down naturally under the action of gravity. When the production line speed fluctuates, the tension of the PET plastic strip changes accordingly. When the strip is taut, the second moving table 18 is driven to move upward; when the strip is loose, the second moving table 18 moves downward under the action of gravity. The up and down movement of the second moving table 18 drives the encoder 17 to operate through the belt 19, and the encoder 17 feeds back the movement information to the controller. The controller obtains the changes in the production line speed in real time based on the signal from the encoder 17 and dynamically adjusts the winding speed of the winding mechanism 4 to ensure that the winding speed is synchronized with the production line speed, and to prevent the PET plastic strip from being pulled apart or tangled.

[0028] The guiding mechanism 5 plays a crucial role in the winding process. The first moving device 6 drives the fixing frame 7 to approach the winding mechanism 4, pressing the pressure roller 11 against the paper tube of the winding mechanism 4. During winding, the pressure roller 11 continuously presses against the wound PET plastic steel strip to prevent the strip from loosening. As the diameter of the PET plastic steel strip roll increases, the first moving device 6 drives the fixing frame 7 to retract accordingly, keeping the pressure roller 11 pressed against the surface of the PET plastic steel strip roll. The first servo motor 8 drives the first moving table 9 to move along the first optical axis 13 via the first lead screw 12, driving the first guide wheel 10 to guide the PET plastic steel strip to reciprocate in a spiral manner around the surface of the paper tube, forming a neat winding layer.

[0029] In this embodiment, the tensioning device 2 and the guiding mechanism 5 work together to achieve stable control of the PET plastic steel tape winding process. The tensioning device 2 monitors and adjusts the tape tension in real time, while the guiding mechanism 5 ensures that the tape is tightly wound. This design effectively solves the winding problem caused by speed fluctuations in the production line, improving product quality and production efficiency. The entire winding process is highly automated, easy to operate, and suitable for continuous production environments.

[0030] Example 3:

[0031] The PET plastic steel tape winding mechanism 4 of this embodiment includes an active mechanism 21 and a driven mechanism 22. The active mechanism 21 consists of a first bracket 23, a first fixed tube assembly 24, and a second servo motor 25. The first bracket 23 is movably mounted on the first fixed tube assembly 24 via a first bearing seat 26, and the drive end of the second servo motor 25 is connected to the first fixed tube assembly 24. The driven mechanism 22 includes a second bracket 27 and a second fixed tube assembly 28, with the second bracket 27 movably mounted on the second fixed tube assembly 28 via a second bearing seat 29. During the winding operation, the operator places both ends of the paper tube onto the first fixed tube assembly 24 and the second fixed tube assembly 28, respectively. After the second servo motor 25 of the active mechanism 21 starts, it drives the first fixed tube assembly 24 to rotate, causing the paper tube to rotate synchronously for PET plastic steel tape winding. The second fixed tube assembly 28 of the driven mechanism 22 starts simultaneously, cooperating with the active mechanism 21 to provide stable support for the paper tube, ensuring that the paper tube maintains smooth rotation during the winding process. The coordinated design of the active mechanism 21 and the driven mechanism 22 not only ensures the stability of the winding process, but also facilitates the installation of the paper tube and the unloading of the full roll of PET plastic steel tape.

[0032] During the winding process, the guiding mechanism 5 drives the first moving platform 9 to approach the winding mechanism 4 via the first moving device 6, so that the pressure roller shaft 11 presses against the paper tube surface of the winding mechanism 4. As the PET plastic steel strip is continuously wound around the paper tube, the diameter of the strip gradually increases, and the first moving device 6 will drive the first moving platform 9 to move backward accordingly, always maintaining the pressure of the pressure roller shaft 11 on the PET plastic steel strip roll. This dynamic pressing mechanism effectively prevents the strip material from loosening or shifting during the winding process.

[0033] Before entering the winding mechanism 4, the PET plastic steel strip undergoes tension adjustment via the tensioning device 2. The strip is guided by the guide roller assembly 15 and the second guide wheel 20 on the second moving table 18. Since the second optical shaft 16 is vertically positioned, the second moving table 18 hangs naturally under gravity. When fluctuations in the production line speed cause changes in the strip tension, the second moving table 18 moves up and down accordingly: when the strip is taut, it moves upwards; when the strip is slack, it falls downwards under gravity. The displacement of the second moving table 18 is transmitted to the encoder 17 via the belt 19. The controller adjusts the winding speed of the winding mechanism 4 in real time based on the feedback signal from the encoder 17, ensuring that the winding speed is synchronized with the production line speed.

[0034] This winding machine achieves stable winding of PET plastic steel strip through the coordinated operation of the winding mechanism 4, the guiding mechanism 5, and the tensioning device 2. The symmetrical arrangement of the driving mechanism 21 and the driven mechanism 22 ensures stable support of the paper tube, the pressure roller 11 of the guiding mechanism 5 guarantees tight winding of the strip, and the dynamic adjustment function of the tensioning device 2 effectively adapts to speed fluctuations in the production line. The entire winding process is automated, which not only improves winding efficiency but also significantly enhances product quality, avoiding problems such as strip breakage or loose winding. This winding machine has a reasonable structural design, is easy to operate, and can meet the continuous operation requirements of PET plastic steel strip production lines.

[0035] Example 4:

[0036] In this embodiment, the first frame 3 is fixedly mounted with a first guide rail 30, a second guide rail 31, a first cylinder 32, and a third servo motor 33. The first guide rail 30 is movably connected to the active mechanism 21 via a third moving platform 34, and the drive end of the first cylinder 32 is fixedly connected to the third moving platform 34. The second guide rail 31 is movably connected to the driven mechanism 22 via a fourth moving platform 35, and the drive end of the third servo motor 33 is drive-connected to the fourth moving platform 35 via a second lead screw 36. The active mechanism 21 includes a first bracket 23, a first fixed cylinder assembly 24, and a second servo motor 25. The first bracket 23 movably mounts the first fixed cylinder assembly 24 via a first bearing seat 26, and the drive end of the second servo motor 25 is drive-connected to the first fixed cylinder assembly 24. The driven mechanism 22 includes a second bracket 27 and a second fixed cylinder assembly 28. The second bracket 27 movably mounts the second fixed cylinder assembly 28 via a second bearing seat 29. The guiding mechanism 5 includes a fixed frame 7, a first servo motor 8, and a first moving stage 9. The first moving stage 9 is movably mounted with a first guide wheel 10 and a pressure roller shaft 11. The drive end of the first servo motor 8 is connected to the first moving stage 9 via a first lead screw 12. The fixed frame 7 is movably mounted with the first moving stage 9 via a first optical shaft 13. The tensioning device 2 includes a second frame 14. The second frame 14 is fixedly mounted with a guide roller shaft assembly 15, a second optical shaft 16, and an encoder 17. The second optical shaft 16 is movably mounted with a second moving stage 18. The second moving stage 18 is connected to the encoder 17 via a belt 19. The second moving stage 18 is movably mounted with a second guide wheel 20.

[0037] In actual operation, the operator first places both ends of the paper tube onto the first fixed tube assembly 24 of the active mechanism 21 and the second fixed tube assembly 28 of the driven mechanism 22, respectively. The first cylinder 32 drives the third moving stage 34 to move along the first guide rail 30, causing the active mechanism 21 to move closer to the driven mechanism 22, so that the first fixed tube assembly 24 and the second fixed tube assembly 28 together clamp and fix the paper tube. Simultaneously, the third servo motor 33 drives the fourth moving stage 35 along the second guide rail 31 via the second lead screw 36, precisely adjusting the working position of the driven mechanism 22 to accommodate paper tubes of different lengths. This adjustment process can be recorded by the servo control system, facilitating rapid subsequent positioning and improving equipment compatibility.

[0038] During the winding operation, the PET plastic steel strip first enters the tensioning device 2 and is guided by the guide roller shaft group 15 and the second guide wheel 20. The second moving table 18 can move up and down on the second optical axis 16, and its gravity keeps the PET plastic steel strip under appropriate tension. When the production line speed fluctuates, causing changes in the strip tension, the second moving table 18 moves up and down accordingly, driving the encoder 17 to operate via the belt 19. The encoder 17 feeds back the position signal to the controller, which adjusts the winding speed of the winding mechanism 4 in real time to ensure a stable winding process. At the same time, the first servo motor 8 of the guiding mechanism 5 drives the first moving table 9 to move along the first optical axis 13 via the first lead screw 12, causing the pressure roller shaft 11 to press against the surface of the paper tube. As the diameter of the PET plastic steel strip gradually increases as it winds around the paper tube, the first moving device 6 drives the first moving table 9 to move backward accordingly, keeping the pressure roller shaft 11 in close contact with the surface of the strip to prevent loosening.

[0039] Through the above structural design, this embodiment achieves automated control of the PET plastic steel tape winding process. The coordinated action of the first cylinder 32 and the third servo motor 33 makes the movement of the active mechanism 21 and the driven mechanism 22 more stable and precise, significantly reducing the labor intensity of operators. The servo control system can store multiple sets of position parameters, and when changing to different specifications of paper tubes, the corresponding parameters can be quickly recalled to achieve precise positioning, greatly shortening the equipment adjustment time. The linkage control between the tensioning device 2 and the winding mechanism 4 effectively adapts to speed fluctuations in the production line, avoiding quality problems such as tape breakage or loose winding. The entire winding process achieves efficient and stable continuous operation, improving production efficiency and product quality consistency.

[0040] Example 5:

[0041] In this embodiment, the fixing frame 7 is fixedly installed with a first support plate 37. The first support plate 37 is provided with an adjustment groove 38, and a limit sensor 39 is fixedly installed in the adjustment groove 38. By adjusting the position of the limit sensor 39, the movement range of the guide mechanism 5 is controlled. The position of the limit sensor 39 can be controlled according to the paper tube of different lengths to ensure that the PET plastic steel strip is wound on the paper tube.

[0042] During the winding process, the guide mechanism 5 drives the PET plastic strip to reciprocate spirally around the surface of the paper tube. The first support plate 37 is fixed to the fixing frame 7, and its adjustment groove 38 is a long strip structure. The limit sensor 39 is fixed at any position in the adjustment groove 38 by bolts or clips. When it is necessary to change the paper tube of different lengths, the operator can loosen the fixing piece of the limit sensor 39, move the sensor along the adjustment groove 38 to the required position, and then re-fix it. The limit sensor 39 is connected to the controller and is used to detect the movement limit position of the first moving stage 9 in the guide mechanism 5. When the first moving stage 9 moves along the first optical axis 13 under the drive of the servo motor, if it approaches the position set by the limit sensor 39, the sensor will send a signal to the controller, and the controller will then stop the servo motor, thereby limiting the travel range of the first moving stage 9. This design ensures that the guide mechanism 5 only moves within the range matching the length of the paper tube, avoiding the PET plastic strip from winding beyond the end of the paper tube or being incompletely covered, ensuring the uniformity and integrity of the winding.

[0043] In practice, the paper tube is installed between the active mechanism 21 and the driven mechanism 22 of the winding mechanism 4. The first moving stage 9 of the guiding mechanism 5 drives the pressure roller 11 to contact the surface of the paper tube, pressing the PET plastic strip during winding. As the winding diameter increases, the first moving stage 9 gradually retracts, maintaining a constant pressure. The position adjustment of the limit sensor 39 directly affects the reciprocating movement range of the first moving stage 9. For example, for shorter paper tubes, the limit sensor 39 is placed near the middle of the adjustment groove 38 to reduce the movement range of the first moving stage 9; for longer paper tubes, the sensor is moved to the far end of the adjustment groove 38 to expand the movement range. Through this adjustable limit mechanism, the winding machine can adapt to various specifications of paper tubes without replacing hardware components, achieving precise control through simple position adjustments.

[0044] In actual production, the PET plastic steel strip enters the winding area after the tensioning device 2 adjusts its tension. The tensioning device 2 senses changes in the strip tension by the up-and-down movement of the second moving stage 18, and the encoder 17 converts the movement signal into speed information and feeds it back to the controller. The controller synchronously coordinates the rotation speed of the winding mechanism 4 and the movement of the guide mechanism 5. The limit sensor 39 serves as a safety guarantee for the position of the guide mechanism 5, ensuring that the first moving stage 9 will not rush out of the effective working area due to inertia during speed fluctuations or emergency stops, preventing equipment collisions or strip entanglement and misalignment. At the same time, the limit sensor 39 is linked with the active mechanism 21 and the driven mechanism 22 of the winding mechanism 4. When the length of the paper tube changes, the driven mechanism 22 adjusts its position via a servo motor, and the guide mechanism 5 adjusts its limit point accordingly, forming a complete adaptive system.

[0045] This embodiment achieves flexible control of the movement range of the guide mechanism 5 through the combination of the adjustment groove 38 and the limit sensor 39. This combination of mechanics and sensing not only improves equipment compatibility but also enhances the stability and reliability of the winding process. Operators can quickly set parameters according to the paper tube specifications, reducing downtime for adjustments and improving production efficiency. Furthermore, the feedback information from the limit sensor 39 can be used to monitor equipment operating status, providing data support for preventative maintenance and extending equipment lifespan. The entire system significantly reduces the complexity of process adjustments caused by variations in paper tube length while ensuring the quality of PET plastic steel tape winding, making it suitable for continuous, multi-specification production environments.

[0048] In the winding operation, the two ends of the paper tube are first fitted onto the first fixed tube assembly 24 of the active mechanism 21 and the second fixed tube assembly 28 of the driven mechanism 22, respectively. At this time, the second cylinder 45 drives the pressure plate 42 to move towards the fixed plate 41. Since both the fixed plate 41 and the pressure plate 42 are provided with inclined surfaces 43, the ring spring 44 is squeezed out under the action of the inclined surfaces 43, and its diameter increases, thus making tight contact with the inner wall of the paper tube and fixing the paper tube. The second servo motor 25 of the active mechanism 21 starts, driving the first fixed tube assembly 24 to rotate the paper tube and begin winding the PET plastic steel strip. The second fixed tube assembly 28 of the driven mechanism 22 cooperates with the active mechanism 21 to ensure that the paper tube rotates stably during the winding process and prevents deviation or shaking.

[0049] The PET plastic steel belt first enters the tensioning device 2 for tension adjustment. The belt is guided by the guide roller assembly 15 and the second guide wheel 20 on the second moving table 18. Since the second optical shaft 16 is vertically positioned, the second moving table 18 hangs naturally under gravity. When fluctuations in the production line speed cause changes in the tension of the PET plastic steel belt, the belt tightens, causing the second moving table 18 to move upwards; when the belt loosens, the second moving table 18 falls under gravity. The up-and-down movement of the second moving table 18 drives the encoder 17 via the belt 19. The encoder 17 feeds back the displacement signal to the controller, which adjusts the winding speed of the winding mechanism 4 in real time to adapt to changes in production line speed and prevent the belt from breaking or becoming tangled.

[0050] The first moving device 6 of the guiding mechanism 5 drives the first moving stage 9 to approach the winding mechanism 4, pressing the pressure roller 11 against the surface of the paper tube. During the winding process, the pressure roller 11 continuously presses the PET plastic steel strip roll to prevent the strip from loosening. As the diameter of the PET plastic steel strip roll increases, the first moving device 6 drives the first moving stage 9 to gradually retreat, ensuring that the pressure roller 11 always maintains appropriate pressure on the roll surface. The first servo motor 8 drives the first moving stage 9 to reciprocate along the first optical axis 13 via the first lead screw 12, so that the PET plastic steel strip is evenly wound around the surface of the paper tube in a spiral manner, forming a neat roll.

[0051] When the paper tube reaches full roll, the second cylinder 45 drives the pressure plate 42 away from the fixed plate 41, the engagement of the inclined plane 43 is released, the ring spring 44 returns to its original shape, its diameter decreases, and it disengages from the inner wall of the paper tube, making it easy to remove the fully rolled PET plastic steel tape. Then, a new empty paper tube is replaced, and the above fixing and winding process is repeated to achieve continuous operation. Through the coordinated design of the active mechanism 21 and the driven mechanism 22, the installation and disassembly of the paper tube are simple and efficient, greatly improving production efficiency. The entire winding process, through real-time feedback from the tensioning device 2 and precise control of the guiding mechanism 5, ensures stable winding quality of the PET plastic steel tape, effectively solving the problem of tape breakage or entanglement caused by fluctuations in production line speed.

[0052] Example 7:

[0053] In this embodiment, the first movable stage 9 is fixedly mounted with a pressing assembly 47 via a second support plate 46. The pressing assembly 47 includes a fixed base 48, an adjusting bolt 49, and a pressing block 50. The fixed base 48 has a hole 51, and the pressing block 50 is fixedly connected to the fixed base 48 via the adjusting bolt 49. The PET plastic steel strip passes through the hole 51, and the pressing block 50 presses against the surface of the PET plastic steel strip. By adjusting the tightness of the adjusting bolt 49, the pressing block 50 can be tightened or loosened to control the tightness of the PET plastic steel strip during winding.

[0054] During the winding process, the PET plastic strip enters the winding machine from the production line and is first tensioned by the tensioning device 2. The tensioning device 2 includes a second frame 14, on which a guide roller assembly 15, a second optical shaft 16, and an encoder 17 are fixedly mounted. A second moving table 18 is movably mounted on the second optical shaft 16. The second moving table 18 is connected to the encoder 17 via a belt 19 and is also movably mounted with a second guide wheel 20. The PET plastic strip is guided by the guide roller assembly 15 and the second guide wheel 20. Since the second optical shaft 16 is vertically set, the second moving table 18 hangs down naturally under the action of gravity. When the production line speed fluctuates, the tension of the PET plastic strip changes. When the strip is taut, the second moving table 18 moves upward; when the strip is loose, the second moving table 18 falls. This movement drives the encoder 17 through the belt 19. The controller adjusts the winding speed of the winding mechanism 4 in real time according to the feedback signal from the encoder 17 to prevent the strip from breaking or becoming tangled.

[0055] The guiding mechanism 5 includes a fixed frame 7, a first servo motor 8, and a first moving stage 9. The first moving stage 9 is movably mounted with a first guide wheel 10 and a pressure roller shaft 11. The drive end of the first servo motor 8 is connected to the first moving stage 9 via a first lead screw 12. The fixed frame 7 is movably mounted with the first moving stage 9 via a first optical shaft 13. The first moving device 6 drives the first moving stage 9 closer to the winding mechanism 4, causing the pressure roller shaft 11 to press against the paper tube of the winding mechanism 4, thus pressing the PET plastic strip tightly during winding to prevent loosening. As the PET plastic strip roll increases in size, the first moving device 6 drives the first moving stage 9 backward, ensuring that the pressure roller shaft 11 continuously presses against the roll.

[0056] The pressure assembly 47 plays a crucial role in the winding process. Adjusting bolt 49 adjusts the pressure of the pressure block 50 on the PET plastic strip, ensuring the strip remains uniformly tight during winding. When the production line speed is stable, the pressure block 50 moderately tightens the strip to prevent slippage between layers. When speed fluctuations cause tension changes, the pressure block 50 responds quickly, fine-tuning the pressure via bolt 49 to prevent the strip from becoming too tight or too loose. This design, combined with real-time feedback from the tensioning device 2, allows the winding machine to adapt to changes in production line speed, improving product quality and production efficiency.

[0057] In operation, the fixed seat 48 of the pressing assembly 47 is securely connected to the first moving platform 9 via the second support plate 46, ensuring stability during movement. After the PET plastic steel belt passes through the belt hole 51, the pressing block 50 acts directly on the belt surface. The rotation of the adjusting bolt 49 can precisely control the position of the pressing block 50, achieving tightening or loosening. This mechanical adjustment method is simple and reliable, requiring no complex electronic control, thus reducing equipment costs and maintenance difficulty. At the same time, the coordinated work of the pressing assembly 47 and the guiding mechanism 5 ensures that the PET plastic steel belt maintains ideal tension throughout the winding process, preventing the belt on the roll from becoming loose or deformed.

[0058] Furthermore, the design of the pressing assembly 47 takes into account long-term durability. The fixing seat 48 and the pressure block 50 are made of high-strength materials, and the adjusting bolt 49 has an anti-loosening function to ensure that it will not fail due to vibration during high-speed winding. Through the precise control of the pressing assembly 47, the tightness of the PET plastic steel tape roll is effectively guaranteed, facilitating subsequent storage and transportation and reducing waste and damage caused by uneven winding. Overall, this embodiment demonstrates the practicality and efficiency of the pressing assembly 47 in the winding machine, solving the problems caused by speed fluctuations in the production line.

[0059] Example 8:

[0060] The PET plastic strip winding machine of this embodiment includes a winding machine body 1 and a tensioning device 2. The winding machine body 1 has a first frame 3, and the first frame 3 is equipped with a guide mechanism 5 via a first moving device 6. The guide mechanism 5 consists of a fixed frame 7, a first servo motor 8, and a first moving platform 9. The first moving platform 9 is movably equipped with a first guide wheel 10 and a pressure roller shaft 11. The drive end of the first servo motor 8 is connected to the first moving platform 9 via a first lead screw 12. The fixed frame 7 is movably equipped with the first moving platform 9 via a first optical shaft 13. The tensioning device 2 includes a second frame 14, which is fixedly equipped with a guide roller shaft group 15, a second optical shaft 16, and an encoder 17. The second optical shaft 16 is movably equipped with a second moving platform 18, which is connected to the encoder 17 via a belt 19. The second moving platform 18 is movably equipped with a second guide wheel 20. The second optical shaft 16 is fixedly equipped with a buffer spring 52, which is located below the second moving platform 18.

[0061] During the winding process, the PET plastic strip first enters the tensioning device 2 and is guided by the guide roller group 15 and the second guide wheel 20. Because the second optical shaft 16 is vertically positioned, the second moving table 18 is in a drooping state under gravity. When the production line is running normally, the PET plastic strip maintains appropriate tension, and the second moving table 18 floats near its equilibrium position. The encoder 17 monitors the positional changes of the second moving table 18 in real time via the belt 19. The controller adjusts the winding speed of the winding mechanism 4 based on the feedback signal from the encoder 17, ensuring that the winding speed is synchronized with the production line speed.

[0062] When the production line suddenly stops, the PET plastic strapping conveyor is interrupted, but the winding mechanism 4 continues to operate due to inertia, causing the strapping to be rapidly tightened. The tightened PET plastic strapping acts on the second guide roller 20, generating an upward pulling force, causing the second moving table 18 to move rapidly upward along the second optical axis 16. At this time, the buffer spring 52 is compressed, absorbing the kinetic energy of the second moving table 18 and slowing its movement speed. The elastic deformation of the buffer spring 52 converts mechanical energy into potential energy, and releases the energy through spring rebound, causing the second moving table 18 to generate damped movement in the vertical direction. This buffering effect prevents the second moving table 18 from stopping abruptly, preventing the PET plastic strapping from breaking due to excessive instantaneous tension.

[0063] Under the action of the buffer spring 52, the upward speed of the second moving table 18 gradually decreases and slowly falls back after reaching its highest point. This process provides the controller with sufficient response time, enabling it to adjust the operating parameters of the winding mechanism 4 in a timely manner. When the production line resumes operation, the buffer spring 52 also helps the second moving table 18 smoothly transition to normal working conditions, avoiding severe vibrations. Through the damping characteristics of the buffer spring 52, the impact of sudden speed changes on the tension of the PET plastic strip is effectively eliminated, ensuring stable winding.

[0064] In this embodiment, the buffer spring 52 enables the tensioning device 2 to possess excellent dynamic response characteristics. When speed fluctuations occur on the production line, the buffer spring 52 absorbs excess energy, smooths out tension changes, and prevents the PET plastic strip from breaking due to sudden tension. Simultaneously, the elasticity of the buffer spring 52 maintains the continuous movement of the second moving table 18, ensuring that the encoder 17 can continuously provide accurate feedback signals, enabling the controller to achieve precise speed adjustment. This structural design significantly improves the adaptability and reliability of the winding machine, ensuring the winding quality of the PET plastic strip.
