Description

Technical Field

[0001] This utility model relates to the field of double-sided fleece fabric production technology, specifically a flipping device for napping double-sided fleece fabric. Background Technology

[0002] Double-sided fleece fabric is widely used in garment manufacturing due to its softness, comfort, and warmth. However, traditional methods require manual turning of the fabric during the napping process, which increases processing time and costs while reducing efficiency. To improve efficiency and save labor costs, a turning device for double-sided fleece fabric napping has been developed. This device effectively enables automatic fabric turning, simplifying the operation and significantly improving processing efficiency.

[0003] For example, the Chinese authorized patent CN222008388U, entitled "An Automatic Turning Device for a Hairline Raising Machine," includes a collection box with four columns fixed to the top. A dustproof box is also fixed to the top of the collection box. A guide roller 1 is rotatably connected between two pairs of columns on the left and right sides. A guide roller 2 located above the guide roller 1 is rotatably connected between the pair of columns on the right side. A guide roller 3 and a cleaning roller are rotatably connected between two diagonally arranged columns from top to bottom. A guide roller 4 is also provided between the two columns on the front side. A transmission motor is fixed to the top of the collection box. The output shaft of the transmission motor is fixed to a transmission roller located next to the guide roller on the right side. An outlet roller is rotatably arranged above the guide roller 4. A vacuum cleaner is fixed inside the collection box. A vacuum cleaner pipe is connected to the upper end of the vacuum cleaner and passes through the top of the collection box.

[0004] While the existing technology can turn double-sided fleece fabric over, it is not very flexible and cannot adjust the fabric's output position, thus it cannot be adapted to various processing equipment and does not meet current needs. Therefore, we propose a turning device for napping double-sided fleece fabric. Utility Model Content

[0005] The purpose of this utility model is to provide a turning device for napping double-sided fleece fabric, so as to solve the problem that the turning device mentioned in the background art cannot adjust the output position of the fabric, thus making it unsuitable for use with various processing equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a turning device for napping double-sided fleece fabric, comprising a base, a rotating frame installed on one side of the upper surface of the base, and the shaft at the bottom of the rotating frame being rotatably connected to the base; a first movable frame provided at the rear end of one side of the rotating frame; a first turning guide roller and a second turning guide roller installed between the rotating frame and the first movable frame; the second turning guide roller being located above the first turning guide roller; and the shafts at both ends of the first turning guide roller being rotatably connected to the first movable frame; a second movable frame provided at the front end of one side of the rotating frame; and two fabric guide rollers installed between the rotating frame and the second movable frame; and the shafts at both ends of the fabric guide rollers being rotatably connected to the second movable frame.

[0007] Preferably, an adjusting motor is fixedly installed on one side of the base, and a worm gear is fixedly installed on the shaft inside the base of the rotating frame. A worm is installed on one side of the worm gear, one end of the worm is rotatably connected to the base, and the other end of the worm is fixed to the output shaft of the adjusting motor through a coupling.

[0008] Preferably, an electric lifting rod is fixedly installed on the upper crossbeam between the rotating frame and the first movable frame, an adjusting frame is installed on the outside of the second flipping guide roller, the shafts at both ends of the second flipping guide roller are rotatably connected to the adjusting frame, and the movable end of the electric lifting rod is fixed to the upper end face of the adjusting frame.

[0009] Preferably, the inner walls of both the rotating frame and the first movable frame are provided with limiting grooves, and the sliding blocks on both sides of the adjusting frame extend into the interior of the limiting grooves.

[0010] Preferably, a fabric turning mechanism is provided on the other side of the rotating frame, and the fabric turning mechanism is fixed to the base. Two turning rollers are installed inside the fabric turning mechanism, and the turning rollers are rotatably connected to the fabric turning mechanism.

[0011] Preferably, an arc-shaped groove is provided on the other side of the upper surface of the base, and guide sliders are fixedly installed at the bottom of both the first movable frame and the second movable frame, and the guide sliders slide and limit the arc-shaped groove.

[0012] Preferably, a connecting frame is fixedly provided at the lower end between the first movable frame and the second movable frame. Both ends of the connecting frame are provided with positioning mechanisms. The positioning mechanism consists of a movable head and a positioning pin. The movable head is fixedly provided on the upper end face of the positioning pin, and the lower end of the positioning pin passes through the connecting frame. The bottom of the arc-shaped groove is provided with arc-shaped positioning holes, and the positioning holes are inserted and engaged with the positioning pin.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model features a fabric guide position adjustment mechanism. By activating the adjustment motor, its output shaft drives the worm gear to rotate. The contact surface between the worm gear and the worm wheel forms a spiral friction transmission surface. The rotation of the worm gear drives the worm wheel to rotate, which in turn drives the shaft at the bottom of the rotating frame to rotate, thus rotating the rotating frame. The rotating frame is fixed to the first and second movable frames, allowing the flipping guide rollers and fabric guide rollers on the first and second movable frames to revolve around the axis of the rotating frame for adjustment. This achieves the adjustment of the fabric guide position. This adjustment method is convenient and easy to operate, suitable for various processing equipment. Furthermore, the self-locking property of the worm gear ensures the stability of the rotating frame after adjustment, ensuring smooth fabric guidance.

[0015] 2. This utility model features a connecting frame guide locking mechanism. Guide sliders are fixedly installed at the bottom of both the first and second movable frames. During the rotation of the rotating frame, the guide sliders slide in the arc groove of the base, further improving the stability of the movement of the first and second movable frames. After moving to the set position, the user presses the movable head to insert the positioning pin at the bottom of the movable head into the positioning hole at the bottom of the arc groove. Under the basic limit of the worm gear, the insertion and cooperation of the positioning pin and the positioning hole further improves the fixing effect of the movable frame.

[0016] 3. This utility model features a flipping guide roller spacing adjustment mechanism. During the flipping process, the fabric first passes through the bottom of the lower guide roller, then bends and passes through the top of the upper guide roller. At this point, the lower end of the original fabric is transformed into the upper end. The fabric then passes through the first and second flipping guide rollers. The electric lifting rod is activated, and the second flipping guide roller is lowered through the adjustment frame until it contacts the upper end of the fabric. This creates a tight fixation between the fabric, the first flipping guide roller, and the second flipping guide roller, preventing wrinkles from forming on the fabric during the flipping process. Finally, the flipped fabric is guided out through the space between the guide rollers. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figure 1-6 This utility model provides an embodiment of a double-sided fleece fabric turning device, comprising a base 1, a rotating frame 4 mounted on one side of the upper surface of the base 1, and a shaft at the bottom of the rotating frame 4 rotatably connected to the base 1. A first movable frame 5 is provided at the rear end of one side of the rotating frame 4. A first turning guide roller 6 and a second turning guide roller 8 are installed between the rotating frame 4 and the first movable frame 5. The second turning guide roller 8 is located above the first turning guide roller 6, and the shafts at both ends of the first turning guide roller 6 are rotatably connected to the first movable frame 5. A second movable frame 18 is provided at the front end of one side of the rotating frame 4. Two fabric guide rollers 10 are installed between the rotating frame 4 and the second movable frame 18, and the shafts at both ends of the fabric guide rollers 10 are rotatably connected to the second movable frame 18. An adjusting motor 14 is fixedly installed on one side of the base 1. A worm gear 16 is fixedly installed on the shaft of the rotating frame 4 inside the base 1. A worm 15 is installed on one side of the worm gear 16. One end of the worm 15 is rotatably connected to the base 1, and the other end of the worm 15 is fixed to the output shaft of the adjusting motor 14 through a coupling.

[0026] By turning on the adjusting motor 14, its output shaft drives the worm 15 to rotate. The contact surface between the worm 15 and the worm wheel 16 forms a spiral friction transmission surface. The rotation of the worm 15 drives the worm wheel 16 to rotate, which in turn drives the shaft at the bottom of the rotating frame 4 to rotate, thereby driving the rotating frame 4 to rotate. Moreover, the rotating frame 4 is fixed to the first movable frame 5 and the second movable frame 18, so that the flipping guide roller and the fabric guide roller on the first movable frame 5 and the second movable frame 18 revolve around the axis of the rotating frame 4 to adjust the fabric guide position.

[0027] Please see Figure 1 , Figure 4 and Figure 5 An electric lifting rod 9 is fixedly installed on the upper crossbar between the rotating frame 4 and the first movable frame 5. An adjusting frame 7 is installed on the outside of the second flipping guide roller 8. The shafts at both ends of the second flipping guide roller 8 are rotatably connected to the adjusting frame 7. The movable end of the electric lifting rod 9 is fixed to the upper end face of the adjusting frame 7. The inner walls of the rotating frame 4 and the first movable frame 5 are provided with limiting grooves 17. The sliding blocks on both sides of the adjusting frame 7 extend into the interior of the limiting grooves 17. A fabric turning mechanism 2 is provided on the other side of the rotating frame 4. The fabric turning mechanism 2 is fixed to the base 1. Two turning rollers 3 are installed inside the fabric turning mechanism 2. The turning rollers 3 are rotatably connected to the fabric turning mechanism 2.

[0028] During the flipping process, the fabric first passes through the bottom of the lower turning roller 3, then bends and passes through the top of the upper turning roller 3. At this point, the lower end of the original fabric is transformed into the upper end. The fabric then passes through the first flipping guide roller 6 and the second flipping guide roller 8. The electric lifting rod 9 is activated, and the second flipping guide roller 8 is lowered through the adjusting frame 7 until it contacts the upper end of the fabric. This forms a tight fixation between the fabric, the first flipping guide roller 6, and the second flipping guide roller 8, preventing wrinkles from forming in the fabric during the flipping process. Finally, the flipped fabric is exported through the turning rollers.

[0029] Please see Figure 1 , Figure 2 and Figure 6 An arc-shaped groove 12 is provided on the other side of the upper surface of the base 1. Guide sliders 22 are fixedly installed at the bottom of the first movable frame 5 and the second movable frame 18, and the guide sliders 22 slide and limit the arc-shaped groove 12. A connecting frame 11 is fixedly provided at the lower end between the first movable frame 5 and the second movable frame 18. A positioning mechanism 19 is provided at both ends of the connecting frame 11. The positioning mechanism 19 consists of a movable head 20 and a positioning pin 21. The movable head 20 is fixedly provided on the upper surface of the positioning pin 21, and the lower end of the positioning pin 21 passes through the connecting frame 11. An arc-shaped positioning hole 13 is provided at the bottom of the arc-shaped groove 12, and the positioning hole 13 is inserted and engaged with the positioning pin 21.

[0030] During the rotation of the rotating frame, the guide slider 22 slides in the arc groove 12 of the base 1, which further improves the stability of the movement of the first movable frame 5 and the second movable frame 18. After moving to the set position, the user presses the movable head 20 to make the positioning pin 21 at the bottom of the movable head 20 insert into the positioning hole 13 at the bottom of the arc groove 12. Under the basic limit of the worm gear 16 and worm 15, the insertion and cooperation of the positioning pin 21 and the positioning hole 13 further improves the fixing effect of the movable frame.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
