Description

Technical Field

[0001] This utility model relates to the field of winding devices, specifically a winding device for knitted fabric. Background Technology

[0002] In the production and processing of knitted fabrics, winding is a crucial step. Traditional knitted fabric winding devices often have many limitations and cannot meet the diverse and efficient production demands of modern manufacturing.

[0003] Low winding efficiency: Traditional winding devices can only wind one type of fabric at a time. When switching to wind different types of knitted fabrics, the machine must be stopped for complex adjustments and replacement of winding components. This not only consumes a lot of time but also seriously affects production efficiency. In the case of large-scale production and diverse orders, frequent downtime for adjustments makes it difficult to guarantee production progress.

[0004] Complex and time-consuming operation: In traditional winding devices, the disassembly and installation of the winding shaft is often cumbersome. The winding shaft is usually connected to the main body of the equipment by bolts, nuts, or other complex fixing devices. When the winding is completed and the winding shaft needs to be replaced, the operator needs to use various tools to disassemble it. During installation, precise alignment and tightening of the fixing parts are required. This process is not only time-consuming and labor-intensive, but also requires a high level of skill from the operator. Improper operation may result in the winding shaft not being installed securely, affecting the subsequent winding quality. Therefore, we propose a winding device for knitted fabrics. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a winding device for knitted fabric, which solves the aforementioned problems.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solution: a winding device for knitted fabric, including a U-shaped mounting base, on both inner walls of the U-shaped mounting base, a turntable is rotatably mounted, and multiple sets of extension blocks are equidistantly mounted on the outer side of the turntable. A circular disc is connected to one side of the extension block corresponding to the center point of the U-shaped mounting base through a snap-fit ​​component, and a winding shaft is provided between the two circular discs.

[0007] Preferably, a sleeve is fixedly installed on one side of the circular disc corresponding to the extension block, and a circular groove is opened on one side of the sleeve corresponding to the extension block. Multiple sets of triangular grooves are equally spaced on the inner wall of the circular groove, and the snap-fit ​​component is inserted into the sleeve.

[0008] Preferably, the snap-fit ​​assembly includes a spring assembly, a gear-shaped snap-fit ​​block, and a plug-in block. The plug-in block is connected to the spring assembly, and the end of the plug-in block facing away from the spring assembly is fixedly connected to the plug-in block. Multiple sets of triangular protrusions are integrally formed at equal intervals on the outer wall surface of the gear-shaped snap-fit ​​block.

[0009] Preferably, the spring assembly includes a circular mounting block fixedly mounted on the extension block and a spring fixedly mounted inside the circular mounting block, wherein one end of the spring extending into the circular mounting block is fixedly connected to the spring.

[0010] Preferably, a circular connecting tube is fixedly installed on the side of the circular disc away from the sleeve. The circular connecting tube is fixedly connected to the winding shaft. An opening is provided on the circular connecting tube. An L-shaped insert is movably inserted into the inside of the circular connecting tube. One bent end of the L-shaped insert extends into the inside of the opening, and one end of the L-shaped insert passes through the circular disc and extends into the inside of the sleeve.

[0011] Preferably, a drive motor is fixedly mounted on one side wall of the U-shaped mounting base, and the output shaft of the drive motor is fixedly connected to the turntable.

[0012] Compared with the prior art, the present invention provides a winding device for knitted fabric, which has the following advantages:

[0013] 1. This knitted fabric winding device features multiple extension blocks on a turntable, with winding shafts positioned between corresponding extension blocks on both sides. This allows for separate winding of different fabric types, significantly improving the device's adaptability to various knitted fabrics. Manufacturing companies no longer need to purchase multiple winding devices for different fabrics, reducing equipment costs and workshop space requirements.

[0014] 2. The winding device for this knitted fabric allows for easy removal of the winding shaft after winding is completed. Simply slide the L-shaped insert and bend one end to press it against the gear-shaped latch. The spring contracts, disengaging the gear-shaped latch from the sleeve, making the winding shaft easy to remove without the need for complex tools. The operation is simple and quick. When installing a new winding shaft, align the sleeve with the gear-shaped latch and press it to engage with the outside of the sleeve to complete the installation. This greatly shortens the winding shaft replacement time and improves production efficiency.

[0015] 3. The winding device for this knitted fabric uses a drive motor to rotate a turntable, allowing for quick adjustment of the winding shaft for unwound fabric. Once the previous winding shaft has finished winding, restarting the motor switches to a new winding shaft to continue winding, eliminating the need for prolonged downtime for adjustments. This effectively reduces production interruptions and improves equipment utilization and production efficiency.

[0016] 4. The knitted fabric winding device can rotate the turntable by starting the drive motor when it is necessary to display the rolled fabric in different positions. Multiple winding shafts rotate synchronously, which can display different types and batches of fabric from all angles. It is intuitive and efficient, making it easy for customers to quickly understand the product information and improve the efficiency of enterprise display and communication.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 A winding device for knitted fabric includes a U-shaped mounting base 1. Turntables 3 are rotatably mounted on the inner walls of both sides of the U-shaped mounting base 1. Multiple sets of extension blocks 4 are equidistantly mounted on the outer side of the turntables 3. A circular disc 10 is connected to one side of the extension block 4 corresponding to the center point of the U-shaped mounting base 1 via a snap-fit ​​assembly. A winding shaft 14 is provided between the two circular discs 10. This device has multiple extension blocks 4 on the turntables 3, and a winding shaft 14 is provided between each pair of corresponding extension blocks 4 on both sides, which can wind up different types of fabrics as needed.

[0024] Furthermore, a sleeve 9 is fixedly installed on one side of the circular disc 10 corresponding to the extension block 4. A circular groove is opened on one side of the sleeve 9 corresponding to the extension block 4. Multiple sets of triangular grooves are equally spaced on the inner wall of the circular groove. The snap-fit ​​component is inserted into the sleeve 9.

[0025] Furthermore, the snap-fit ​​assembly includes a spring assembly, a gear-shaped snap-fit ​​block 8, and a plug-in block 7. The plug-in block 7 is connected to the spring assembly, and the end of the plug-in block 7 facing away from the spring assembly is fixedly connected to the plug-in block 7. Multiple sets of triangular protrusions are integrally formed at equal intervals on the outer wall surface of the gear-shaped snap-fit ​​block 8.

[0026] Furthermore, the spring assembly includes a circular mounting block 5 fixedly mounted on the extension block 4 and a spring 6 fixedly mounted inside the circular mounting block 5. One end of the spring 6 extending into the circular mounting block 5 is fixedly connected to the spring 6. When the spring 6 rebounds normally, the gear-shaped locking block 8 is locked inside the circular groove of the sleeve 9, and the triangular protrusions are respectively locked in the corresponding triangular grooves.

[0027] Furthermore, a circular connecting tube 11 is fixedly installed on the side of the circular disc 10 away from the sleeve 9. The circular connecting tube 11 is fixedly connected to the take-up shaft 14. An opening 12 is provided on the circular connecting tube 11, and an L-shaped insert 13 is movably inserted into the interior of the circular connecting tube 11. One bent end of the L-shaped insert 13 extends into the interior of the opening 12, and one end of the L-shaped insert 13 passes through the circular disc 10 and extends into the interior of the sleeve 9. After the fabric to be wound on the take-up shaft 14 is finished, the bent end of the L-shaped insert 13 is slid. The L-shaped insert 13 moves towards the sleeve 9, then the gear-shaped locking block 8 is pressed, and the spring 6 retracts. After the insert 7 retracts into the circular mounting block 5, the gear-shaped locking block 8 is no longer engaged with the sleeve 9. Then, the entire winding shaft 14 with the fabric is removed, and then the winding shaft 14 without the fabric is installed. The sleeve 9 is aligned with the gear-shaped locking block 8, and then the gear-shaped locking block 8 is pressed towards the circular mounting block 5. Then, the spring 6 retracts, and the gear-shaped locking block 8 is engaged with the outer side of the sleeve 9, thus completing the installation.

[0028] Furthermore, a drive motor 2 is fixedly installed on one side wall of the U-shaped mounting base 1. The output shaft of the drive motor 2 is fixedly connected to the turntable 3. When the fabric is finished being rolled up, and it is necessary to display the rolled-up fabric in different positions, the drive motor 2 is started. The drive motor 2 drives the turntable 3 on one side to rotate, and then drives multiple winding shafts 14 to rotate, thus displaying the rolled-up fabric in different positions.

[0029] Structural Description:

[0030] U-shaped mounting base 1: The basic support structure of the entire winding device. Its inner walls on both sides provide mounting positions for the rotation of the turntable 3. The drive motor 2 is fixedly installed on one side wall to provide power support for the operation of the entire device.

[0031] Drive motor 2: Fixedly mounted on one side wall of the U-shaped mounting base 1, its output shaft is fixedly connected to the turntable 3. The operation of drive motor 2 drives the turntable 3 to rotate, thereby adjusting the position of the take-up shaft 14 and meeting the rotation requirements during the fabric take-up process. When it is necessary to display fabric being taken up at different positions, starting drive motor 2 can drive multiple take-up shafts 14 to rotate.

[0032] Turntable 3: Rotatably mounted on the inner walls of both sides of the U-shaped mounting base 1, with multiple sets of extension blocks 4 equidistantly mounted on its outer side. Turntable 3 rotates under the drive of drive motor 2, thereby driving the extension blocks 4 and the connected winding shaft 14 to adjust their position and rotate for winding.

[0033] Extension blocks 4: Equivalently installed on the outer side of the turntable 3, each extension block 4 is connected to the circular disk 10 via a snap-fit ​​assembly on one side corresponding to the center point of the U-shaped mounting base 1. The extension blocks 4 serve to connect the turntable 3 and the circular disk 10, providing an installation position for the snap-fit ​​assembly, thereby realizing the installation and fixation of the winding shaft 14.

[0034] Circular mounting block 5: Fixedly mounted on extension block 4, it is part of the spring assembly. Spring 6 is installed inside to provide elastic support for the operation of the snap-fit ​​assembly, so that gear-shaped snap-fit ​​block 8 can snap-fit ​​and disengage from sleeve 9 under certain conditions.

[0035] Spring 6: Fixedly installed inside the circular mounting block 5, with one end connected to the circular mounting block 5 and the other end connected to the plug-in block 7. Under normal conditions, the spring 6 rebounds, causing the gear-shaped locking block 8 to lock into the circular groove of the sleeve 9, thereby fixing the winding shaft 14; when subjected to external pressure, the spring 6 contracts, causing the gear-shaped locking block 8 to disengage from the sleeve 9, facilitating the disassembly of the winding shaft 14.

[0036] Insertion block 7: Connected to spring 6, with its end facing away from spring 6 fixedly connected to gear-shaped locking block 8. Under the action of spring 6, as spring 6 extends and retracts, it drives gear-shaped locking block 8 to move, thereby controlling the engagement and disengagement of gear-shaped locking block 8 with sleeve 9.

[0037] Gear-shaped locking block 8: Multiple sets of triangular protrusions are integrally formed at equal intervals on the outer wall surface, and are fixedly connected to the insertion block 7. When the spring 6 returns normally, the gear-shaped locking block 8 is locked inside the circular groove of the sleeve 9, and its triangular protrusions are respectively locked in the corresponding triangular grooves on the inner wall of the circular groove of the sleeve 9, thereby fixing the winding shaft 14; when it is squeezed by the L-shaped insertion block 13, it retracts into the circular mounting block 5 together with the insertion block 7, and disengages from the sleeve 9.

[0038] Sleeve 9: It is fixedly installed on one side of the circular disc 10 corresponding to the extension block 4. A circular groove is opened on one side of the circular disc 10 corresponding to the extension block 4. Multiple sets of triangular grooves are equally spaced on the inner wall of the circular groove, which are used to cooperate with the gear-shaped locking block 8 in the locking assembly to realize the detachable connection between the circular disc 10 and the extension block 4, thereby fixing the winding shaft 14.

[0039] Circular disc 10: A take-up shaft 14 is provided between the two circular discs 10. One side of the corresponding extension block 4 is connected to the snap-fit ​​assembly through the sleeve 9, and a circular connecting pipe 11 is fixedly installed on the side opposite to the sleeve 9. The circular disc 10 serves to connect the take-up shaft 14 and the extension block 4, ensuring the stability of the take-up shaft 14 during the take-up process.

[0040] Circular connecting tube 11: Fixedly installed on the side of the circular disc 10 away from the sleeve 9, and fixedly connected to the take-up shaft 14, providing an installation position for the take-up shaft 14 and ensuring a stable connection between the take-up shaft 14 and the circular disc 10. The circular connecting tube 11 has an opening 12 for the movable insertion of the L-shaped insert 13.

[0041] Opening 12: Opened on the circular connecting tube 11, providing space for the bent end of the L-shaped insert 13 to move inside the circular connecting tube 11 and extend into the sleeve 9, thereby enabling operation of the snap-fit ​​assembly and controlling the disassembly and installation of the winding shaft 14.

[0042] L-shaped insert 13: It is movably inserted into the inside of the circular connecting tube 11, with one bent end extending into the inside of the opening 12 and the other end penetrating through the circular disc 10 and extending into the inside of the sleeve 9. When it is necessary to disassemble the take-up shaft 14, slide the bent end of the L-shaped insert 13 to move it towards the sleeve 9, pressing the gear-shaped locking block 8 to disengage the take-up shaft 14 from the extension block 4; when installing the take-up shaft 14, the L-shaped insert 13 can also be used to assist in adjusting the position of the locking assembly.

[0043] Winding shaft 14: Located between the two circular discs 10, it is used to wind up the knitted fabric. It is connected to the extension block 4 via a snap-fit ​​assembly, enabling detachable installation. It can wind up different types of fabrics as needed, and can be easily disassembled and replaced after winding.

[0044] Working principle: When winding is required, start drive motor 2, drive motor 2 drives turntable 3 to rotate, and then adjust one winding shaft 14 of the unwound fabric. After winding is completed, start drive motor 2 again, drive turntable 3 to rotate, and adjust one winding shaft 14 of the unwound fabric again. After winding is completed, remove winding shaft 14, slide one bent end of L-shaped insert 13 to move L-shaped insert 13 towards sleeve 9, and then press gear-shaped locking block 8. Spring 6 retracts. When insert block 7 retracts into circular mounting block 5, gear-shaped locking block 8 is no longer engaged with sleeve 9. Then remove the entire winding shaft 14 with the wound fabric, and then install the winding shaft 14 with the unwound fabric. Align sleeve 9 with gear-shaped locking block 8, and then press gear-shaped locking block 8 towards circular mounting block 5. Then spring 6 retracts, and gear-shaped locking block 8 engages with the outer side of sleeve 9, thus completing the installation.
