The fixing frame drives the rotating plate to rotate around the connecting shaft through the mounting plate and the support shaft. The rotating plate drives the tensioning member to move outward and open through the fixed shaft. The tensioning member stretches the Velcro on the reel and provides tension to it, so that the Velcro is fixed on the reel. This ensures that the Velcro remains in a tensioned state during the reeling process, further enhancing the stability of the Velcro and ensuring that the Velcro is tight and wrinkle-free.

[0047] 2. When the hook and loop fastener is rolled beyond the disc, the positioning plate can automatically increase the size of the positioning plate according to the need to roll the hook and loop fastener to different thicknesses, thereby achieving different degrees of rolling of the hook and loop fastener to meet different production requirements;

[0048] 3. Through the combination of motor, coupling and worm, the power of the motor can be effectively transmitted to the winding mechanism to ensure the smooth operation of the equipment. The cooperation of the worm and worm wheel realizes the deceleration of power, which is suitable for winding operations that require low speed and high torque, and avoids damage to the hook and loop tape due to excessive speed;

[0049] 4. The infrared sensor monitors the diameter of the Velcro on the reel and transmits the monitored data to the control system in real time. After receiving the feedback signal from the infrared sensor, the control system processes and analyzes the current diameter data. Based on the monitored diameter changes, the control system automatically adjusts the speed of the drive motor to ensure that the reeling speed matches the Velcro diameter. This effectively prevents damage to the coil caused by reeling too fast or too slow, ensuring product integrity.

[0050] 5. The electric push rod pushes the bracket connected to it to move back and forth, adjusts the position of the winding wheel, and matches the relative position of the winding wheel and the Velcro to achieve the best winding effect, improve production efficiency and product quality, and adapt to different operational requirements.

DETAILED DESCRIPTION

[0060] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0061] In the description of this application, it should be noted that the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn according to the actual proportional relationship. Technologies, methods and equipment known to ordinary technicians in the relevant fields may not be discussed in detail, but where appropriate, technologies, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, so once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0062] Example 1:

[0063] like Figures 1-4 As shown, this embodiment provides a hook and loop fastener winding device, comprising:

[0064] Bracket 1;

[0065] The hollow shaft 2 is rotatably mounted on the bracket 1;

[0066] The disc 3 is arranged on the hollow shaft 2;

[0067] The winding wheel 4 is arranged on the disc 3, and the interior of the winding wheel 4 is hollow;

[0068] The transmission mechanism 7 is provided on the bracket 1 and is used to drive the hollow shaft 2 to rotate;

[0069] The tensioning mechanism 5 is provided on the hollow shaft 2 and cooperates with the reel 4 to tension and fix the hook and loop fastener;

[0070] The tensioning mechanism 5 comprises:

[0071] There are multiple guide grooves 51, which are evenly spaced along the circumferential direction on the winding wheel 4;

[0072] The cylinder 52 is disposed inside the hollow shaft 2, and the piston rod of the cylinder 52 extends out of the hollow shaft 2;

[0073] The support shell 53 is arranged inside the winding wheel 4;

[0074] There are four ear plates 54, all of which are arranged on the supporting shell 53, and each group of ear plates 54 has two;

[0075] The connecting shaft 55 is provided between the two ear plates 54 on the same side;

[0076] The rotating plate 56 is rotatably mounted on the connecting shaft 55;

[0077] A fixing bracket 57 is provided on the piston rod of the cylinder 52;

[0078] There are multiple mounting plates 58, which are evenly spaced along the circumferential direction and arranged on the fixing frame 57;

[0079] The support shaft 59 is provided on the mounting plate 58, and the rotating plate 56 is connected to the support shaft 59;

[0080] The fixed shaft 510 is provided at the upper end of the rotating plate 56;

[0081] The tensioning member 511 is disposed on the fixed shaft 510 and is located in the guide groove 51 .

[0082] In this technical solution, the design of the Velcro winding device is intended to efficiently and stably wind the Velcro, ensuring that the Velcro is tensioned and fixed during the winding process, avoiding slack and wrinkles, and improving production efficiency and product quality. The hollow shaft 2 is driven to rotate by the transmission mechanism 7 to achieve an automated winding process, reducing the burden of manual operation. The tensioning mechanism 5 ensures that the Velcro is in a taut state during the winding process, avoiding product quality problems caused by slack. The use of a cylinder 52 as a power source makes the tensioning mechanism 5 stable and reliable, extending the service life of the equipment.

[0083] Working process: When the Velcro needs to be rolled up, first wrap one end of the Velcro around the winding wheel 4, then start the cylinder 52, the piston rod of the cylinder 52 extends, driving the fixed frame 57 to move forward, and the fixed frame 57 drives the rotating plate 56 to rotate around the connecting shaft 55 through the mounting plate 58 and the support shaft 59. The rotation of the rotating plate 56 drives the fixed shaft 510 to move outward, and the fixed shaft 510 drives the tensioning member 511 to move outward along the guide groove 51 and open, so that the tensioning member 511 stretches the Velcro on the winding wheel 4 and provides it with tensioning force, so that the Velcro is fixed on the winding wheel 4. When the tensioning member 511 provides appropriate tension for the Velcro, the cylinder 52 is closed. Then the transmission mechanism 7 is started to work, driving the hollow shaft 2 to rotate. The reel 4 reels the hook and loop tape step by step as the hollow shaft 2 rotates. The disc 3 serves as a limit for the reeling of the hook and loop tape. During the reeling process, the operator can monitor the reeling state of the hook and loop tape and adjust the pressure of the cylinder 52 as needed to achieve the best tensioning effect. If the reeling is found to be uneven or the tension is inappropriate, adjustments can be made quickly through the adjustment function of the cylinder 52. When the hook and loop tape is reeled to a predetermined length, the transmission mechanism 7 is closed and the cylinder 52 is started. The piston rod of the cylinder 52 retracts and drives the fixing frame 57 to move backward. The fixing frame 57 passes through the mounting plate 5 8 and the support shaft 59 drive the rotating plate 56 to rotate in the opposite direction along the connecting shaft 55. The reverse rotation of the rotating plate 56 causes the fixed shaft 510 to drive the tensioning member 511 to rotate in the opposite direction. The tensioning member 511 is retracted from the guide groove 51, and then the tensioning member 511 is no longer in contact with the Velcro. The operator can process or pack the rolled-up Velcro, thereby ensuring that the Velcro remains in a tensioned state during the rolling process, further enhancing the stability of the Velcro, and ensuring that the Velcro is tight and wrinkle-free, which not only improves production efficiency, but also ensures the stability, reliability and adaptability of product quality, so that it can flexibly respond to different production needs in actual applications.

[0084] like Figure 1 As shown, in this embodiment, the rear side of the disc 3 is optimized and provided with a positioning plate 6 for increasing or decreasing the volume according to the rolled-up Velcro. The positioning plate 6 is connected to the disc 3 by bolts. There are multiple positioning plates 6, which are evenly spaced along the circumferential direction.

[0085] In this technical solution, the positioning plate 6 is dynamically increased or decreased according to the volume of the wound Velcro. When the Velcro is wound beyond the disc 3, the positioning plate 6 can automatically add the size of the positioning plate 6 as needed to wind the Velcro to different thicknesses, thereby achieving different degrees of winding of the Velcro. By precisely controlling the position of the positioning plate 6, the tightness and uniformity of the winding can be better controlled, and the deformation and relaxation of the Velcro during the winding process can be reduced. The bolt connection method makes the installation and disassembly of the positioning plate 6 more convenient, and the operator can quickly adjust it as needed to adapt to different production requirements. By precisely controlling the winding volume, shutdown or waste caused by uneven volume is avoided, and production efficiency is improved.

[0086] Example 2:

[0087] This embodiment provides a Velcro winding device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0088] like Figure 1 、 Figure 5 、 Figure 6 and Figure 8 As shown, in this embodiment, the transmission mechanism 7 is optimized and includes:

[0089] A support plate 71 is provided at the rear side of the bracket 1;

[0090] The frame 72 is mounted on the support plate 71 by bolt connection;

[0091] A driving motor 73 is provided on the frame 72;

[0092] A coupling 74 is provided on the output shaft of the drive motor 73;

[0093] A worm 75 is provided on the coupling 74;

[0094] The housing 76 is provided on the support plate 71 , and the worm 75 is located in the housing 76 ;

[0095] A transmission shaft 77 is rotatably mounted on the housing 76 , with one end of the transmission shaft 77 passing through and extending out of the housing 76 ;

[0096] A worm gear 78 is provided on the transmission shaft 77 and cooperates with the worm 75;

[0097] Sprocket 79, provided on transmission shaft 77 and hollow shaft 2;

[0098] The chain 710 is wound between the two worm gears 78 .

[0099] In this technical solution, the transmission mechanism 7 provides stable and reliable power transmission to achieve efficient winding of the Velcro. Through the combination of the motor, the coupling 74 and the worm 75, the power of the motor can be effectively transmitted to the winding mechanism to ensure the smooth operation of the equipment. The cooperation of the worm 75 and the worm wheel 78 realizes the deceleration of power, which is suitable for winding operations requiring low speed and high torque, and avoids damage to the Velcro due to excessive speed. The design of the support plate 71, the frame 72 and the housing 76 ensures the overall stability of the transmission mechanism 7 while reducing the floor space of the equipment. The design connected by bolts makes the disassembly and maintenance of each component more convenient, reducing maintenance costs.

[0100] Workflow: The operator activates drive motor 73, which begins to rotate. Drive motor 73 transmits power to worm 75 via coupling 74. Worm 75 rotates within housing 76, driving worm wheel 78. The rotation of worm wheel 78 is then transmitted to drive shaft 77 via drive shaft 78. The coordination between worm 75 and worm wheel 78 reduces power, allowing drive shaft 77 to rotate at a lower speed, suitable for the winding of the Velcro. A sprocket 79 on drive shaft 77 is connected to another sprocket 79, with chain 710 looped between them, forming a stable power transmission system. The rotation of chain 710 drives hollow shaft 2, which in turn rotates disk 3 and reel 4, beginning to wind the Velcro. During the winding process, the operator can monitor the equipment's operation in real time, adjusting the transmission speed or checking the tension of chain 710 as needed, facilitating maintenance. When the hook and loop fastener reaches the desired length, the device stops, completing the winding process. This device achieves efficient and stable power transmission, ensuring a smooth and reliable winding process. Furthermore, its compact structure and easy-to-maintain design enhance its practical application value, making it suitable for a wide range of hook and loop fastener production needs.

[0101] like Figure 1 、 Figure 5 and Figure 6 As shown, in this embodiment, it is optimized that a protective cover 8 is provided between the sprocket 79 and the outer side of the chain 710 .

[0102] In this technical solution, a protective cover 8 is added between the sprocket 79 and the chain 710 in the Velcro winding device. The protective cover 8 can effectively prevent the operator from accidentally touching the sprocket 79 and the chain 710 when the device is running, reducing the safety hazards caused by mechanical movement and ensuring operational safety. The protective cover 8 can prevent foreign matter such as dust and dirt from entering between the sprocket 79 and the chain 710, keeping the transmission system clean, reducing wear and tear, and increasing the service life of the equipment. By covering the sprocket 79 and the chain 710, the protective cover 8 can reduce the noise generated when the equipment is running to a certain extent, improve the working environment, and protect the sprocket 79 and the chain 710 while preventing any external objects from accidentally entering the working area. When maintenance or inspection is required, the operator can easily open the protective cover 8 to check the condition of the sprocket 79 and the chain 710. The design of the protective cover 8 makes cleaning and lubrication easier, keeping the transmission system in good operating condition.

[0103] Example 3:

[0104] This embodiment provides a Velcro winding device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0105] like Figure 1 and Figure 8 As shown, in this embodiment, it is optimized and also includes an infrared sensor 9 for monitoring the diameter of the Velcro wound by the winding wheel 4 and feeding back to the control system 10 in real time. The control system 10 controls the operating state of the drive motor 73 according to the signal feedback from the infrared sensor 9 to achieve smooth winding of the Velcro.

[0106] In this technical solution, the infrared sensor 9 can monitor the diameter change of the Velcro on the winding wheel 4 in real time to ensure that it can adapt to the winding requirements under different diameter conditions. By providing real-time feedback to the control system 10, the control system 10 can automatically adjust the operating state of the drive motor 73 according to the change in the diameter of the Velcro to maintain a stable winding speed. Accurate diameter monitoring and automatic adjustment help to reduce problems such as uneven tightness and overlap during the winding process, thereby improving the quality of the finished product. Real-time monitoring and adjustment can effectively prevent damage to the coil caused by winding too fast or too slow, ensure the integrity of the product, improve the intelligence level of the equipment, reduce manual intervention, and reduce operational risks.

[0107] Workflow: The operator starts the equipment, and the transmission system begins operating, driving the reel 4 to rewind the Velcro tape. An infrared sensor 9 begins monitoring the tape diameter on the reel 4 and transmits the data in real time to the control system 10. After receiving the feedback signal from the infrared sensor 9, the control system 10 processes and analyzes the current diameter data. Based on the monitored diameter changes, the control system 10 automatically adjusts the speed of the drive motor 73 to ensure that the rewinding speed matches the tape diameter. If the diameter increases, the control system 10 slows the motor speed; if the diameter decreases, the motor speed is increased appropriately to achieve smooth rewinding. Throughout the rewinding process, the infrared sensor 9 continuously monitors the diameter, and the control system 10 continuously adjusts the motor state to ensure stability and consistency of the rewinding process. By introducing the infrared sensor 9 and its coordinated operation with the control system 10, the Velcro rewinding equipment achieves precise control and intelligent management of the rewinding process, not only improving rewinding quality and efficiency, but also significantly reducing operational risks, providing a higher level of reliability and automation for the production line.

[0108] Example 4:

[0109] This embodiment provides a Velcro winding device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0110] like Figure 7 As shown, in this embodiment, the optimization further includes an adjustment mechanism 11, and the adjustment mechanism 11 includes:

[0111] Bottom plate 111, located at the bottom of the bracket 1;

[0112] Guide plates 112 are provided on both sides of the top of the bottom plate 111;

[0113] A chute 113 is formed between the two guide plates 112;

[0114] The slide plate 114 is provided at the bottom of the bracket 1 and is slidably connected to the slide groove 113;

[0115] The mounting frame 115 is provided on the rear side of the base plate 111;

[0116] The electric push rod 116 is disposed on the mounting frame 115 and is connected to the bracket 1 .

[0117] In this technical solution, the adjustment mechanism 11 can flexibly adjust the position of the winding wheel 4 according to different Velcro specifications and winding requirements to ensure the best winding effect. Through the design of the base plate 111 and the guide plate 112, the adjustment mechanism 11 can improve the stability of the device and reduce vibration, thereby ensuring the smoothness of the winding process. The use of the electric push rod 116 automates the adjustment process, simplifies operation, and improves the operating efficiency of the device. It can adapt to a variety of Velcros of different specifications and thicknesses, enhancing the versatility of the device.

[0118] Workflow: The operator starts the equipment, and the drive motor 73 and the control system 10 start working. Before starting to reel in, according to the required specifications of the Velcro, the electric push rod 116 is started. The electric push rod 116 pushes the bracket 1 connected to it to move back and forth. As the bracket 1 moves, the slide 114 slides in the slide groove 113. The design of the guide plate 112 ensures the stability of the slide 114 during the movement. The electric push rod 116 continues to run and adjusts the position of the reel 4 to match the relative position of the reel 4 with the Velcro to achieve the best reeling effect. After the adjustment is completed, the equipment starts to reel normally, which can better cope with Velcro of different specifications, improve production efficiency and product quality, and adapt to different operational requirements. It not only improves the flexibility and convenience of operation, but also enhances the stability and adaptability of reeling.
