Description

Technical Field

[0001] This utility model relates to the technical field of large roll air pressure devices, specifically to a large roll air pressure device for an air-jet loom. Background Technology

[0002] With the trend of intelligent and efficient development in the textile industry, air-jet looms have become mainstream equipment due to their high-speed weaving capabilities. However, the quality of fabric winding directly affects the subsequent processing of products and market competitiveness.

[0003] Currently, traditional air-jet looms mainly rely on take-up rollers to wind the fabric during the winding process. However, during the output process of air-jet looms, the fabric is not easy to bear force, which can easily lead to loosening inside the rolled fabric during the winding process. During transportation or storage, it is easy to deform due to compression and wrinkles, affecting the flatness of the fabric and increasing the difficulty of subsequent cutting, dyeing and other processes. At the same time, loose fabric rolls take up a lot of space, reducing warehousing and transportation efficiency. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a large-roll air pressure device for an air-jet loom, which is used to solve the technical problem of the fabric being relatively loose during the winding process in the prior art.

[0005] According to one aspect, at least one embodiment of the present invention provides a large-roll air pressure device for an air-jet loom, installed on the loom body, including a take-up roller rotatably mounted on the loom body, a first motor mounted on the loom body, the output end of the first motor being fixedly connected to the take-up roller, and further including a first positioning roller, positioning blocks, a pressure roller, an installation mechanism, and an angle adjustment mechanism. The first positioning roller is rotatably mounted on one side of the loom body located on the take-up roller, and the positioning blocks are fixedly mounted on both ends of the sidewall of the first positioning roller. The pressure roller is disposed on one side of the two positioning blocks. The installation mechanism is disposed between the pressure roller and the positioning blocks for installing and fixing the pressure roller and the positioning blocks. The angle adjustment mechanism is disposed between the loom body and the positioning blocks for adjusting the angle of the positioning blocks.

[0006] Preferably, the angle adjustment mechanism includes a second positioning roller and an electric push rod. The second positioning roller is rotatably mounted on one side of the first positioning roller of the loom body. The electric push rod is mounted on the second positioning roller, and the output end of the electric push rod is hinged to the side wall of the adjacent positioning block.

[0007] Furthermore, the installation mechanism includes an annular groove, a mounting block, a mounting opening, a mounting frame, and a limiting mechanism. The annular groove is provided on both sides of the sidewall of the pressure roller. The mounting block is fixedly mounted on the sidewall of the positioning block closest to the pressure roller. The sidewall of the mounting block has an arc shape and abuts against the bottom of the annular groove. The mounting opening is provided on both sides of the positioning block located on the mounting block. A U-shaped mounting frame is provided on the side of the pressure roller away from the mounting block. The mounting frame extends into the annular groove, and both ends of the mounting frame pass through the mounting opening and are slidably connected to the sidewall of the mounting opening. The limiting mechanism is located between the positioning block and the mounting frame for positioning the mounting frame and the positioning block.

[0008] Furthermore, both the sidewalls of the mounting bracket and the sidewalls of the mounting block are inlaid with ball bearings, which contact the bottom of the annular groove.

[0009] Furthermore, the limiting mechanism includes a first cavity, a second limiting port, a limiting block, and a relative moving mechanism. The first cavity is formed within the positioning block, and the two opposite side walls of the first cavity are each provided with a first limiting port. The two opposite side walls of the mounting bracket are each provided with a second limiting port. The shapes of the first limiting port and the second limiting port are adapted to each other. The limiting block is slidably disposed within the first limiting port. The relative moving mechanism is disposed within the first cavity and is used to drive the two limiting blocks to move relative to each other.

[0010] Based on the above scheme, the relative movement mechanism includes an adjusting disk, an adjusting rod, and a driving mechanism. The adjusting disk is rotatably mounted on the inner top wall of the first cavity. Two rotating shafts are rotatably mounted at the eccentric position of the adjusting disk. The adjusting rod is fixedly mounted on the side wall of the rotating shaft. The end of the adjusting rod away from the rotating shaft is hinged to the side wall of the adjacent limiting block. The driving mechanism is located between the positioning block and the adjusting disk and is used to drive the adjusting disk to rotate.

[0011] Based on the above scheme, the driving mechanism includes a driving rod and a handwheel. The driving rod is fixedly mounted on the adjustment plate and extends through the side wall of the first cavity to the positioning block. The handwheel is fixedly mounted at the end of the driving rod away from the adjustment plate.

[0012] Based on the above scheme, a torsion spring is fitted on the drive rod, and the two ends of the torsion spring are fixedly connected to the handwheel and the positioning block, respectively.

[0013] The beneficial effects of the embodiments of this utility model are as follows:

[0014] 1. In this utility model, by setting up an angle adjustment mechanism, during the winding process, the two positioning blocks can be adjusted by the operation of the electric push rod. At the same time, the angle adjustment of the positioning blocks causes the roll pressure roller to press on the wound fabric, thereby facilitating the improvement of the tightness of the fabric during the winding process.

[0015] 2. In this utility model, by setting up the installation mechanism, after the roll pressure roller is placed on one side of the installation block, the installation frame can be fastened onto the annular groove and pass through the installation opening. Then, by working the relative moving mechanism, one end of the limiting block is driven into the second limiting opening, which facilitates the fixing of the installation frame by the cooperation of the limiting block with the first limiting opening and the second limiting opening, and thus facilitates the installation and fixing of the roll pressure roller by the cooperation of the installation frame and the installation block.

[0016] 3. In this utility model, through the operation of the relative movement mechanism, the drive rod and the adjustment plate can be rotated by rotating the handwheel, and at the same time, the two limit blocks can be moved by rotating shaft and adjustment rod, so as to facilitate the fixation of the mounting frame by moving the limit blocks.

[0031] like Figures 1-6 As shown, this invention illustrates a large-roll air pressure device for an air-jet loom in one embodiment of the present invention. The device is mounted on the loom body 1 and includes a take-up roller 2, which is rotatably mounted on the loom body 1. A first motor 3 is mounted on the loom body 1, and the output end of the first motor 3 is fixedly connected to the take-up roller 2. The device also includes a first positioning roller 4, positioning blocks 5, a pressure roller 6, a mounting mechanism, and an angle adjustment mechanism. The first positioning roller 4 is rotatably mounted on one side of the take-up roller 2 on the loom body 1. Positioning blocks 5 are fixedly mounted at both ends of the sidewall of the first positioning roller 4. The pressure roller 6 is positioned on one side of the two positioning blocks 5. The mounting mechanism is positioned between the pressure roller 6 and the positioning blocks 5 for mounting and fixing the pressure roller 6 and the positioning blocks 5. The angle adjustment mechanism is positioned between the loom body 1 and the positioning blocks 5 for adjusting the angle of the positioning blocks 5.

[0032] Reference Figure 1 and Figure 2 The angle adjustment mechanism includes a second positioning roller 7 and an electric push rod 8. The second positioning roller 7 is rotatably mounted on one side of the first positioning roller 4 on the loom body 1. An electric push rod 8 is installed on the second positioning roller 7. The output end of the electric push rod 8 is hinged to the side wall of the adjacent positioning block 5. Specifically, during the winding process, the two positioning blocks 5 can be adjusted by the operation of the electric push rod 8. At the same time, the angle adjustment of the positioning blocks 5 drives the pressure roller 6 to press on the winding fabric, thereby facilitating the improvement of the tightness of the fabric during the winding process.

[0033] Reference Figures 2-6The installation mechanism includes an annular groove 9, an installation block 10, an installation port 11, an installation frame 12, and a limiting mechanism. Annular grooves 9 are provided on both sides of the sidewall of the pressure roller 6. An installation block 10 is fixedly installed on the sidewall of the positioning block 5 near the pressure roller 6. The sidewall of the installation block 10 is arc-shaped and abuts against the bottom of the annular groove 9. Installation ports 11 are provided on both sides of the positioning block 5 located on the installation block 10. A U-shaped installation frame 12 is provided on the side of the pressure roller 6 away from the installation block 10. The installation frame 12 extends into the annular groove 9, and both ends of the installation frame 12 pass through the installation port 11 and are slidably connected to the sidewall of the installation port 11. The limiting mechanism is located between the positioning block 5 and the installation frame 12 to position the installation frame 12 and the positioning block 5. Ball bearings 13 are embedded in the sidewall of the installation frame 12 and the sidewall of the installation block 10, and the ball bearings 13 contact the bottom of the annular groove 9.

[0034] Furthermore, the limiting mechanism includes a first cavity, a second limiting port 15, a limiting block 16, and a relative moving mechanism. The first cavity is formed within the positioning block 5. Each of the two opposite sidewalls of the first cavity has a first limiting port 14, and each of the two opposite sidewalls of the mounting bracket 12 has a second limiting port 15. The shapes of the first limiting port 14 and the second limiting port 15 are adapted to each other. The limiting block 16 is slidably disposed within the first limiting port 14. The relative moving mechanism is disposed within the first cavity and is used to drive the two limiting blocks 16. 6. Relative movement is performed. Specifically, after the pressure roller 6 is placed on one side of the mounting block 10, the mounting frame 12 can be fastened onto the annular groove 9 and pass through the mounting opening 11. Then, the operation of the relative movement mechanism drives one end of the limiting block 16 to extend into the second limiting opening 15. This facilitates the fixing of the mounting frame 12 by the cooperation of the limiting block 16 with the first limiting opening 14 and the second limiting opening 15, and facilitates the installation and fixing of the pressure roller 6 by the cooperation of the mounting frame 12 and the mounting block 10.

[0035] Reference Figures 2-6The relative movement mechanism includes an adjusting plate 17, an adjusting rod 19, and a drive mechanism. The adjusting plate 17 is rotatably mounted on the inner top wall of the first cavity. Two rotating shafts 18 are rotatably mounted at the eccentric position of the adjusting plate 17. An adjusting rod 19 is fixedly mounted on the side wall of the rotating shaft 18. The end of the adjusting rod 19 away from the rotating shaft 18 is hinged to the side wall of the adjacent limiting block 16. The drive mechanism is located between the positioning block 5 and the adjusting plate 17 and is used to drive the adjusting plate 17 to rotate. The drive mechanism includes a drive rod and a handwheel 20. The drive rod is fixedly mounted on the side wall of the limiting block 16. The drive rod extends through the side wall of the first cavity and out of the positioning block 5, and is placed on the adjustment plate 17. The handwheel 20 is fixedly set at the end of the drive rod away from the adjustment plate 17. A torsion spring is fitted on the drive rod, and the two ends of the torsion spring are fixedly connected to the handwheel 20 and the positioning block 5 respectively. Specifically, the rotation of the handwheel 20 can drive the drive rod and the adjustment plate 17 to rotate, and at the same time, the two limit blocks 16 are pushed to move through the rotating shaft 18 and the adjustment rod 19, so as to facilitate the fixation of the mounting bracket 12 by the movement of the limit blocks 16.

[0036] In this embodiment, during use, after the operator places the pressure roller 6 on one side of the mounting block 10, the mounting bracket 12 can be fastened onto the annular groove 9 and pass through the mounting opening 11. Then, the operator rotates the handwheel 20, which drives the drive rod and the adjusting plate 17 to rotate. At the same time, the rotating shaft 18 and the adjusting rod 19 push the two limiting blocks 16 to move, so that one end of the limiting block 16 can extend into the second limiting opening 15 through the movement of the limiting block 16. Then, the limiting block 16 respectively connects with the first... The cooperation of the limiting port 14 and the second limiting port 15 fixes the mounting frame 12, thereby enabling the mounting frame 12 and the mounting block 10 to be used to fix the roll pressure roller 6. After that, the operator wraps the fabric around the take-up roller 2 and takes the fabric up by rotating the take-up roller 2. During the take-up process, the electric push rod 8 can drive the two positioning blocks 5 to adjust their angles. At the same time, the angle adjustment of the positioning blocks 5 causes the roll pressure roller 6 to press on the take-up fabric, thereby improving the tightness of the fabric during the take-up process.
