Description

Technical Field

[0001] This utility model relates to the field of sofa fabric production technology, and in particular to a high-efficiency sofa fabric winding device. Background Technology

[0002] Sofa fabric is a general term or abbreviation for the textile fabrics used to make various sofas. Sofa fabrics include imitation linen, chenille, jacquard fabric, composite fabric, suede, flocked fabric, hot stamping fabric, embossed fabric, and chenille gauze. Sofa fabric production requires a winding device.

[0003] A search revealed a Chinese patent (authorization announcement number CN214878795U) disclosing a high-efficiency fabric rewinding device. The device includes a platform with a processing box vertically connected to its surface. The processing box has an inlet on one side and an outlet on the side away from the inlet. A protective box is vertically connected to the platform, located on the outlet side of the processing box. A fixing plate is fixedly connected inside the processing box, and a flattening roller is rotatably connected to the end of the fixing plate away from the processing box. While this patented technology can flatten fabric, preventing wrinkles and ensuring product quality, it also incorporates an electric heating element and hydraulic cylinder for ironing and flattening, further preventing wrinkles and maintaining product quality. Additionally, a brush is included for dust removal, ensuring thorough dust removal and preventing any impact on product quality.

[0004] However, the above-mentioned device still has some drawbacks in actual use. The most obvious one is that during production, it is difficult to remove the rolled roller from the device. In addition, workers need to stop the device to replace the new rolling roller during the removal process, which makes continuous production impossible. This method reduces the production efficiency of sofas. Utility Model Content

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0031] Reference Figure 1-4 A high-efficiency sofa fabric winding device includes a winding frame 1, a main roller 2 rotatably mounted inside the winding frame 1, two support frames 3 fixedly connected at equal intervals to the outer side of the main roller 2, a winding roller 4 disposed between the two support frames 3, a hinge 14 disposed on one side of each support frame 3, and an arc-shaped component 13 disposed at one end of each support frame 3. The arc-shaped component 13 is rotatably mounted on the outer side of the support frame 3 via the hinge 14. A first half-stud 11 is fixedly connected to the outer side of the support frame 3, and a second half-stud 12 is fixedly connected to the outer side of the arc-shaped component 13. A locking nut 10 is threadedly connected between the first half-stud 11 and the second half-stud 12. The winding roller 4 enables the winding of the sofa fabric, and the locking nut 10 secures the first half-stud 11 on the support frame 3. The first half of the stud 11 is fixed together with the second half of the stud 12 on the arc-shaped part 13. The first half of the stud 11 and the second half of the stud 12 can be integrated into a whole stud. Without affecting the rotation of the take-up roller 4, the take-up roller 4 can be stably placed on the support frame 3. After the take-up roller 4 finishes taking up the sofa fabric, the locking nut 10 can be unscrewed, and the operator can easily replace the take-up roller 4. The finished take-up roller 4 can be rotated to the rear of the take-up frame 1, and the new take-up roller 4 can be rotated to the production area. In this way, the finished take-up roller 4 can be removed from the support frame 3 during the take-up process, and a new take-up roller 4 can be installed for production without any additional machine stoppage, which greatly improves the production efficiency of the sofa fabric.

[0032] Specifically, a transmission assembly is provided on the outer side of the winding frame 1. The transmission assembly includes a servo motor 15 located on one side of the winding frame 1. A chuck 16 is fixedly connected to the output shaft of the servo motor 15. Several locking parts 18 are fixedly connected to the side of the chuck 16 near the winding roller 4. The winding roller 4 has locking holes 17 inside that cooperate with the locking parts 18. When the locking part 18 is inserted into the corresponding locking hole 17, the rotation of the output shaft of the servo motor 15 can drive the corresponding winding roller 4 to rotate, thereby achieving the purpose of winding the sofa. A pushing assembly is provided inside the winding frame 1. The push assembly includes a cylinder 8 fixedly installed on the outside of the take-up frame 1. A slide groove 6 is provided inside the take-up frame 1 and below the servo motor 15. The cooperation between the slide groove 6 and the slider 7 makes the servo motor 15 more stable during movement. The push assembly also includes a slider 7 slidably installed inside the slide groove 6. The piston rod of the cylinder 8 extends into the interior of the slide groove 6 and is fixedly connected to the slider 7. By extending the piston rod of the cylinder 8, the power of the servo motor 15 can be transmitted to the take-up roller 4. When the piston rod of the cylinder 8 retracts, the power of the servo motor 15 cannot be transmitted.

[0033] Specifically, a drive motor is fixedly installed on the outside of the winding frame 1. The output shaft of the drive motor extends into the inside of the winding frame 1 and is fixedly connected to the rotation shaft of the main roller 2. By rotating the output shaft of the drive motor, the main roller 2 and multiple support frames 3 can be driven to rotate, so as to realize the back-and-forth alternating operation of multiple support frames 3. The inside of the winding frame 1 is provided with a mating groove 9 for use with the winding roller 4. The snap-fit ​​parts 18 are all snapped into the corresponding snap-fit ​​holes 17, so that the snap-fit ​​state between the chuck 16 and the winding roller 4 is more stable. A controller 5 is fixedly installed on the outside of the winding frame 1. The cylinder 8, servo motor 15 and drive motor are all electrically connected to the controller 5. The controller 5 can control the cylinder 8, servo motor 15 and drive motor to start and stop.

[0034] Working principle: First, when the take-up roller 4 needs to be installed, the first half stud 11 on the support frame 3 and the second half stud 12 on the arc-shaped part 13 can be fixed together by using the locking nut 10. The first half stud 11 and the second half stud 12 can be integrated into a whole stud. Without affecting the rotation of the take-up roller 4, the take-up roller 4 can be stably placed on the support frame 3. Then, the cylinder 8 and the servo motor 15 are started by the controller 5. After the docking work of the snap-fit ​​part 18 and the snap-fit ​​hole 17 is completed, the power of the output shaft of the servo motor 15 can be transmitted to the take-up roller 4, thereby realizing the purpose of taking up the sofa fabric.

[0035] After the take-up roller 4 finishes taking up the sofa fabric, the piston rod of the controllable cylinder 8 retracts, causing the locking piece 18 to disengage from the locking hole 17. Then, the drive motor is started, and the taken-up roller 4 is rotated to the rear of the take-up frame 1. The new take-up roller 4 is then rotated to the production area. Then, the operator can unscrew the locking nut 10 to easily replace the take-up roller 4. In addition, the above method allows the taken-up roller 4 to be removed from the support frame 3 during the take-up process, and a new take-up roller 4 to be installed for production without any additional machine stoppage.
