Description

Technical Field

[0001] This application relates to the technical field of textile machinery, and in particular to a widely adaptable textile roller. Background Technology

[0002] The word "roller" is a transliteration of the English word "roller," referring to a cylindrical rotating part in textile machinery that performs functions such as feeding, drafting, and outputting. Its core function is to form a jaw with rubber rollers and aprons to grip the yarn for drafting, directly affecting the yarn uniformity.

[0003] In related technologies, one can refer to the Chinese utility model patent with authorization announcement number CN201390818Y, which discloses a textile roller, which includes a shaft and a roller. The shaft is connected to the roller, and the roller is formed in one piece, which is firm and ensures a smooth surface without burrs or snagging, thus effectively guaranteeing the quality of the product.

[0004] However, in actual operation, the textile rollers mentioned above have limited applicability to fabrics of different sizes and widths because their length is fixed. Often, the entire roller needs to be disassembled and replaced, which is time-consuming, labor-intensive, and results in low work efficiency. Utility Model Content

[0005] To improve the applicability of textile rollers to different types of fabrics, this application provides a textile roller with wide adaptability.

[0006] This application provides a widely adaptable textile roller, which adopts the following technical solution:

[0007] A widely adaptable textile roller includes a roller shaft and a roller surface. The roller shaft is connected to the rotating shaft of a textile machine. A connecting device is provided on the roller shaft. The roller surface is detachably mounted on the roller shaft via the connecting device. The connecting device includes:

[0008] A connecting block is provided, which slides radially on the roller shaft. A plurality of connecting blocks are provided, and the plurality of connecting blocks are evenly distributed circumferentially with the center of the roller shaft as the center.

[0009] A driving mechanism is provided, which is mounted on a roller and is used to drive the connecting block to move. A snap-fit ​​groove is provided on the inner side wall of the roller surface, and the connecting block is snapped into the snap-fit ​​groove under the action of the driving mechanism.

[0010] By adopting the above technical solution, a connecting block and a drive mechanism are installed on the roller shaft. The roller surface is fixed by using the drive mechanism to drive the connecting block to engage with the engagement groove on the inner side of the roller surface. When the roller surface needs to be replaced according to different types of fabrics, it is only necessary to use the drive mechanism to drive the connecting block to disengage from the engagement groove. This is convenient and quick, and there is no need to disassemble the roller shaft, which greatly improves the replacement efficiency.

[0011] Optionally, the drive mechanism includes:

[0012] A drive disk is rotatably mounted on a roller shaft, and the drive disk has an inclined moving hole along the radial direction;

[0013] A drive column, the bottom end of which is disposed on the connecting block, and the top end of which is inserted into the moving hole;

[0014] A limiting component is disposed on the roller shaft and is used to limit the rotational position of the drive disc.

[0015] By adopting the above technical solution, rotating the drive disk causes the moving hole on the drive disk to move, the moving hole moves the drive column, the drive column moves the connecting block, and after the connecting block moves to engage with the locking groove, the rotation position of the drive disk is limited by the limiting component, thus realizing the work of fixing the roller surface by the roller shaft drive connecting block.

[0016] Optionally, the limiting component includes:

[0017] Two limiting clamps are provided, both of which are slidably disposed on the roller shaft along the roller shaft axis, and the two limiting clamps are respectively located on both sides of the drive disc;

[0018] Two electric push rods are provided, both of which are mounted on the roller shaft and are used to push two limiting clamps to clamp the drive disc. The power supply of both electric push rods is connected to the power supply for driving the rotating shaft.

[0019] By adopting the above technical solution, the two electric push rods are activated to move away from each other. The movement of the two electric push rods drives the two limiting clamps to move. After the two limiting clamps move away from each other and disengage from the drive disc, the drive disc can be rotated freely to adjust the position of the connecting block. When the drive disc rotates to the target position, the two electric push rods are activated to drive the two limiting clamps to clamp the drive disc, thereby completing the limiting work of the rotation position of the drive disc.

[0020] Optionally, the roller shaft is provided with a positioning mechanism for positioning the roller surface during installation, the positioning mechanism comprising:

[0021] An infrared light emitter is mounted on a roller.

[0022] A battery box, which is mounted on a roller and electrically connected to an infrared light emitter, contains button batteries.

[0023] A positioning plate is disposed on the inner side wall of the roller surface. When the positioning plate is irradiated by infrared light emitted by an infrared light emitter, the snap-fit ​​groove in the roller surface aligns with the position of the connecting block.

[0024] By adopting the above technical solution, after the infrared light emitter is turned on, the infrared light emitter emits infrared light into the inside of the roller surface. At this time, the roller surface is rotated, and when the positioning plate is found to be irradiated by the infrared light emitted by the infrared light emitter, it indicates that the snap-fit ​​groove in the roller surface is aligned with the position of the connecting block. This completes the positioning of the relative position of the roller surface and the roller shaft when installation is required, eliminating the need to rotate the roller surface repeatedly for calibration, and greatly improving the installation efficiency.

[0025] Optionally, an arc-shaped guide surface is provided at the opening of the snap-fit ​​groove located on the inner side of the roller surface.

[0026] By adopting the above technical solution, an arc-shaped guide surface is opened at the opening of the snap-fit ​​groove. When the connecting block moves and snaps into the snap-fit ​​groove, the guide surface guides the connecting block, making it easier for the connecting block to enter the snap-fit ​​groove, reducing the snap-fit ​​difficulty and improving the snap-fit ​​efficiency.

[0027] Optionally, a rubber pad is laid on the inner bottom wall of the snap-fit ​​groove, and anti-slip texture is formed on the end face of the connecting block that contacts the rubber pad.

[0028] By adopting the above technical solution, a rubber pad is laid on the inner bottom wall of the snap-fit ​​groove, and anti-slip texture is opened on the end face of the connecting block that contacts the rubber pad. This greatly enhances the connection strength when the snap-fit ​​block and the snap-fit ​​groove are snapped together, and reduces the probability of slippage or micro-vibration at the connection point when the roller shaft drives the roller surface to rotate.

[0029] Optionally, the drive disk has a threaded hole, and a movable handle is threadedly connected to the drive disk through the threaded hole.

[0030] By adopting the above technical solution, a movable handle can be detachably installed on the drive disk through a threaded hole. When it is necessary to rotate the drive disk, the movable handle installed through the thread makes it easier for the operator to rotate the drive disk, thus improving the ease of operation.

[0031] Optionally, a flashlight is provided on the movable handle, and the flashlight has a built-in battery.

[0032] By adopting the above technical solution, a battery-powered flashlight is installed on the mobile handle, which can illuminate the space between the roller shaft and the roller surface, making it easier for workers to install the mobile handle.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. By installing a connecting block and a drive mechanism on the roller shaft, and using the drive mechanism to drive the connecting block to engage with the snap-fit ​​groove on the inner side of the roller surface, the roller surface is fixedly installed. When it is necessary to change the roller surface according to different types of fabrics, it is only necessary to use the drive mechanism to drive the connecting block to disengage from the snap-fit ​​groove, which is convenient and quick, without the need to disassemble the roller shaft, greatly improving the replacement efficiency.

[0035] 2. By activating two electric push rods to move away from each other, the movement of the two electric push rods drives the movement of two limit clamps. After the two limit clamps move away from each other and disengage from the drive disc, the drive disc can be rotated freely to adjust the position of the connecting block. When the drive disc rotates to the target position, the two electric push rods are activated to drive the two limit clamps to clamp the drive disc, thus completing the limiting work of the rotation position of the drive disc.

[0036] 3. By installing a battery-powered flashlight on the moving handle, the space between the roller shaft and the roller surface can be illuminated, making it easier for workers to install the moving handle. Attached Figure Description

[0040] The following is in conjunction with the appendix Figure 1 -Appendix Figure 2 This application will be described in further detail.

[0041] This application discloses a widely adaptable textile roller.

[0042] Reference Figure 1 The widely adaptable textile roller includes a roller shaft 11 and a roller surface 12. The roller shaft 11 is connected to the rotating shaft of the textile machinery. A connecting device 2 is provided on the roller shaft 11, and the roller surface 12 is detachably mounted on the roller shaft 11 through the connecting device 2.

[0043] Reference Figure 1 and Figure 2 The connecting device 2 includes connecting blocks 21 and a driving mechanism 22. Four connecting blocks 21 are provided, each sliding radially along the roller shaft 11 and evenly distributed circumferentially around the axis of the roller shaft 11. The driving mechanism 22 is mounted on the roller shaft 11 and drives the connecting blocks 21 to move. A locking groove 13 is provided on the inner wall of the roller surface 12, and the connecting blocks 21 engage with the locking groove 13 under the action of the driving mechanism 22.

[0044] Reference Figure 1 and Figure 2 The drive mechanism 22 includes a drive disc 23, a drive column 24, and a limiting assembly 25. The drive disc 23 is rotatably mounted on the roller shaft 11. Four inclined moving holes 26 are evenly distributed radially on the surface of the drive disc 23. The bottom end of the drive column 24 is fixedly connected to the outer wall of the connecting block 21, and the top end of the drive column 24 extends into the moving hole 26.

[0045] Reference Figure 1 and Figure 2 When the roller surface 12 needs to be replaced according to different types of fabrics, the roller surface 12 can be disassembled simply by rotating the drive disk 23 to move the moving hole 26 on the drive disk 23. The movement of the moving hole 26 moves the drive column 24, which in turn moves the connecting block 21, causing the connecting block 21 to disengage from the locking groove 13. When installing the roller surface 12, simply rotate the drive disk 23 to engage the connecting block 21 with the locking groove 13. The replacement process is convenient and quick, eliminating the need to disassemble the roller shaft 11, thus greatly improving replacement efficiency.

[0046] Reference Figure 1 and Figure 2 The limiting assembly 25 is mounted on the roller shaft 11 and is used to limit the rotational position of the drive disk 23. The limiting assembly 25 includes two limiting clamps 27 and two electric push rods 28. The two limiting clamps 27 are slidably mounted on the roller shaft 11 along the axial direction of the roller shaft 11, and the two limiting clamps 27 are located on both sides of the drive disk 23. The two electric push rods 28 are mounted on the roller shaft 11 and are located on opposite sides of the two limiting clamps 27, and the power supply of the two electric push rods 28 is connected to the power supply for the rotation of the drive shaft.

[0047] Reference Figure 2The two electric actuators 28 are activated and move away from each other, causing the two limiting clamps 27 to move as well. Once the limiting clamps 27 have moved away from each other and disengaged from the drive disc 23, the drive disc 23 can be freely rotated to adjust the position of the connecting block 21. When the drive disc 23 rotates to the target position, the two electric actuators 28 are activated again, causing the two limiting clamps 27 to clamp the drive disc 23, thus completing the limiting of the drive disc 23's rotational position.

[0048] Reference Figure 1 and Figure 2 The roller 11 is equipped with a positioning mechanism 3 for positioning the roller surface 12 during installation. The positioning mechanism 3 includes an infrared light emitter 31, a battery box 32, and a positioning plate 33. The infrared light emitter 31 is fixedly installed on the outer wall of the roller 11. The battery box 32 is fixedly installed on the roller 11 and electrically connected to the infrared light emitter 31. A button battery is installed inside the battery box 32. The positioning plate 33 is fixedly installed on the inner wall of the roller surface 12.

[0049] Reference Figure 2 After the infrared light emitter 31 is turned on, it emits infrared light into the roller surface 12. When the roller surface 12 is rotated, it is found that the positioning plate 33 is irradiated by the infrared light emitted by the infrared light emitter 31, which means that the snap-fit ​​groove 13 in the roller surface 12 is aligned with the connecting block 21. This completes the positioning of the relative positions of the roller surface 12 and the roller shaft 11 when installation is required. There is no need to rotate the roller surface 12 repeatedly for calibration, which greatly improves the installation efficiency.

[0050] Reference Figure 2 An arc-shaped guide surface 14 is provided at the opening of the snap-fit ​​groove 13 located inside the roller surface 12. A rubber pad 15 is laid on the inner bottom wall of the snap-fit ​​groove 13. Anti-slip texture 16 is provided on the end face of the connecting block 21 that contacts the rubber pad 15. By setting the rubber pad 15 and the anti-slip texture 16, the connection strength between the snap-fit ​​block and the snap-fit ​​groove 13 is greatly enhanced, and the probability of slippage or micro-vibration at the connection point when the roller shaft 11 drives the roller surface 12 to rotate is reduced.

[0051] Reference Figure 2 The drive disc 23 has threaded holes on its surface, and a movable handle 17 is threadedly connected to the drive disc 23 through these holes. A battery-powered flashlight 18 is fixedly mounted on the movable handle 17. When it is necessary to rotate the drive disc 23, the movable handle 17 allows the operator to rotate the drive disc 23 more conveniently, improving operational ease. At the same time, the flashlight 18 illuminates the space between the roller shaft 11 and the roller surface 12, making it easier for the operator to install the movable handle 17.

[0052] The working principle of this application embodiment is as follows:

[0053] The roller surface 12 is fixedly installed by rotating the drive disk 23 to drive the connecting block 21 to engage with the snap-fit ​​groove 13 on the inner side of the roller surface 12. When the roller surface 12 needs to be replaced according to different types of fabric, it is only necessary to rotate the drive disk 23 to drive the connecting block 21 to disengage from the snap-fit ​​groove 13. This is convenient and quick, and there is no need to disassemble the roller shaft 11, which greatly improves the replacement efficiency.

[0054] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
