Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and in particular to a yarn bobbin changing device and winding machine for preparing fiber knitted fabrics. Background Technology

[0002] A winding machine is a specialized piece of equipment in the textile industry. Its main function is to rewind the yarn from the spinning process into larger, more stable packaged yarns, providing a suitable yarn package for subsequent weaving, dyeing, and other processes. As the final step in spinning and the first step in weaving, it plays a crucial "bridge" role in the textile production process.

[0003] In the existing technology, when the yarn bobbin of the winding machine is replaced, the rigid clamping mechanism is prone to damage to fragile bobbins such as paper, and it is not easy to adapt to different bobbin sizes. Sometimes, manual adjustment of the clamp is required, resulting in a long bobbin replacement cycle and low efficiency, with poor applicability and compatibility. Utility Model Content

[0004] This utility model discloses a yarn bobbin changing device and a winding machine for preparing fiber knitted fabrics, aiming to solve the technical problem that when changing yarn bobbins in a winding machine, the rigid clamping mechanism is prone to damage to fragile bobbins such as paper, and is not easy to adapt to different specifications of bobbin sizes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a yarn bobbin changing device for preparing fiber knitted fabrics, comprising a guide rail seat; a sliding seat slidably connected to the top of the guide rail seat; a rotating seat rotatably connected to the top of the sliding seat; a hydraulic cylinder fixedly connected to the top of the rotating seat; a mounting frame disposed above the hydraulic cylinder, the bottom of the mounting frame being fixedly connected to the driving end of the hydraulic cylinder; two sliding frames, each slidably connected to the outside of one end of the mounting frame; and a collection box fixedly connected to the top of the sliding seat. The adaptable operation module is located on two sliding frames. Each module includes a fixed base, with fixed holes on both sliding frames. The two fixed bases are fixedly connected to the corresponding fixed holes. Each fixed base has multiple circumferentially spaced sliding slots, each containing a sliding plate. Clamping airbags are fixedly connected to the sliding plates. The module also includes two air pumps, each fixedly connected above the corresponding sliding frame. An annular connecting pipe is fixedly connected above each sliding frame, and the two annular connecting pipes are connected to the corresponding... The output end of the air pump is connected to the mounting bracket. Two electric telescopic rods are fixedly connected to the top of the mounting bracket. The two electric telescopic rods are centrally symmetrical. The drive ends of both electric telescopic rods are fixedly connected to corresponding sliding brackets. Multiple connecting pipes are provided on both annular connecting pipes. The ends of these connecting pipes away from the annular connecting pipes are connected to corresponding clamping airbag components. Multiple telescopic airbag components are fixedly connected to the top of both fixed bases at equal circumferential intervals. One end of each telescopic airbag component is fixedly connected to a corresponding sliding plate component. Multiple conveying pipes are provided on both annular connecting pipes. These conveying pipes are located away from the annular connecting pipes. One end of each connecting pipe is connected to a corresponding telescopic airbag component. A rotating gear ring is fixedly connected to the outside of the rotating seat, and a universal motor is fixedly connected to the top of the rotating seat. A rotating gear is fixedly connected to the output end of the universal motor, and the teeth of the rotating gear can mesh with the rotating gear ring.

A transmission rack is fixedly connected to the inner wall of one side of the sliding seat, and the teeth of the transmission gear can mesh with the transmission rack. A fixed frame is provided on one side of the guide rail seat, and a transmission machine is provided above the fixed frame.

[0006] With an adaptive operating module, when the empty yarn tube is positioned between multiple sliding plates, the air pump is activated. Air is pumped into the telescopic airbag component via an annular connecting pipe and a delivery pipe. The multiple telescopic airbag components expand synchronously, pushing the sliding plates towards the central empty yarn tube. Simultaneously, air is pumped into the clamping airbag component via an annular connecting pipe and a connecting pipe, clamping and fixing the empty yarn tube. Then, the hydraulic cylinder is activated to push the mounting frame upward, causing the empty yarn tube to detach from the placement rod. The synchronous expansion of the telescopic airbag component and the clamping airbag component can achieve flexible clamping, realizing stable gripping and non-destructive fixing of empty yarn tubes of different specifications without frequent adjustment of the clamp specifications. At the same time, it effectively avoids damage to fragile tubes such as paper, increasing the applicability and convenience of the device.

The winding machine body is disposed on one side of a guide rail seat, and a plurality of placement rods are equally spaced on the winding machine body. A control panel is disposed on one side of the winding machine body.

[0008] As can be seen from the above, the yarn bobbin replacement device and winding machine for fiber knitted fabric preparation provided by this utility model, through the adaptive operation module, utilizes the synchronous expansion of the telescopic airbag and the clamping airbag to complete the flexible clamping, realizes stable gripping and non-destructive fixing of empty yarn bobbins of different specifications, eliminates the need for frequent adjustment of clamp specifications, and effectively avoids damage to fragile bobbins such as paper, thereby increasing the applicability and convenience of the device.

Clamping airbags 505 are fixedly connected to each of the multiple sliding plates 504. The adaptable operation module 5 also includes air pumps 503. Both air pumps 503 are fixedly connected above the corresponding sliding frames 19, and annular connecting pipes 502 are fixedly connected above each of the two sliding frames 19. Both annular connecting pipes 502 are connected to the output end of the corresponding air pump 503. The top of the mounting bracket 18 is fixed. Two electric telescopic rods 20 are connected, and the two electric telescopic rods 20 are centrally symmetrical. The driving ends of the two electric telescopic rods 20 are fixedly connected to the corresponding sliding frames 19. Multiple connecting pipes 507 are provided on each of the two annular connecting pipes 502. The ends of the multiple connecting pipes 507 away from the annular connecting pipes 502 are all connected to the corresponding clamping airbag components 505. Multiple telescopic airbag components 506 are fixedly connected to the top of the two fixed seats 501 at equal intervals around their circumference. One end of each telescopic airbag component 506 is fixedly connected to the corresponding sliding plate component 504. Multiple conveying pipes 508 are provided on each of the two annular connecting pipes 502. The multiple conveying pipes 508 are located away from the annular connecting pipes 502. One end of 02 is connected to the corresponding telescopic airbag component 506. A rotating gear ring 15 is fixedly connected to the outside of the rotating seat 14, and a general motor 16 is fixedly connected to the top of the rotating seat 14. A rotating gear 17 is fixedly connected to the output end of the general motor 16. The teeth of the rotating gear 17 can mesh with the rotating gear ring 15. A drive motor 12 is fixedly connected to the bottom of the sliding seat 3. A transmission gear 13 is fixedly connected to the output end of the drive motor 12, and a transmission rack 2 is fixedly connected to the inner wall of one side of the sliding seat 3. The teeth of the transmission gear 13 can mesh with the transmission rack 2.

[0018] Reference Figure 5A winding machine includes a yarn bobbin changing device for preparing fiber knitted fabric as described above, and a winding machine body 9. The winding machine body 9 is disposed on one side of the guide rail seat 1. Multiple placement rods 11 are evenly arranged on the winding machine body 9, and a control panel 10 is disposed on one side of the winding machine body 9.

[0019] Working principle: The winding machine body 9 is started via control panel 10 to perform winding operations. The drive motor 12 is started to rotate the transmission gear 13. Through the meshing of the transmission gear 13 and the transmission rack 2, the sliding seat 3 is driven to slide on the guide rail seat 1. After reaching the designated position, the electric telescopic rod 20 pushes the sliding frame 19 to slide outward, so that the fixed seat 501 is directly above the empty yarn bobbin. The hydraulic cylinder 4 is started to drive the mounting frame 18 to descend until the empty yarn bobbin is located between multiple sliding plates 504. The air pump 503 is started, and air is pumped into the telescopic airbag component 506 through the annular connecting pipe 502 and the conveying pipe 508. Multiple telescopic airbag components 506 expand synchronously, pushing the sliding plate 504 to slide towards the central empty yarn bobbin. At the same time, air is pumped into the clamping airbag component 505 through the annular connecting pipe 502 and the connecting pipe 507, so that the air... The yarn bobbin is clamped and fixed, and then the hydraulic cylinder 4 is activated to push the mounting frame 18 upward, causing the empty yarn bobbin to detach from the placement rod 11. This allows for the replacement of yarn bobbins of different specifications. The flexible clamping of the telescopic airbag 506 and the clamping airbag 505 prevents damage to fragile materials such as paper yarn bobbins. At the same time, the sliding plate 504 and the clamping airbag 505 at the other end clamp the yarn bobbin conveyed by the conveyor 8. The general motor 16 is activated to rotate the rotating gear 17. Through the meshing of the rotating gear 17 and the rotating gear ring 15, the rotating seat 14 is rotated, causing the empty yarn bobbin to be carried to the top of the collection box 6 and then fall for collection. The general motor 16 continues to drive the rotating gear 17, causing the other end to rotate and move to the top of the placement rod 11. The hydraulic cylinder 4 then drives the mounting frame 18 to descend again, completing the replacement of the yarn bobbin.
