Description

Technical Field

[0001] This utility model relates to yarn winding, and more particularly to a yarn winding machine. Background Technology

[0002] Some commercially available yarn balling machines can wind yarn into balls. These machines include a base, a first rotating frame, a winding drum, a first drive mechanism, a second drive mechanism, and a yarn guide frame. When the yarn balling machine is working, the first drive mechanism drives the first rotating frame and the winding drum to rotate relative to the base around a first axis. The second drive mechanism drives the winding drum to rotate relative to the first rotating frame around a second axis, with the central axis of the winding drum coaxial with the second axis. The yarn guide frame guides the yarn from the previous process, and the winding drum pulls the yarn to wrap around its outer perimeter, forming a yarn ball. After winding, the yarn ball is pulled out along the central axis of the winding drum, detaching from the drum and forming a yarn ball with a central hole. However, the yarn balling machines described above produce yarn balls of limited size and variety, lacking versatility. Utility Model Content

[0034] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0035] Reference Figures 1 to 4This utility model discloses a yarn spinning machine, comprising a base 100, a first rotating frame 200, a yarn drum 300, a first driving mechanism 400, a second driving mechanism 500, and a yarn guide frame 600. The first rotating frame 200 is rotatably mounted on the base 100 about a first axis 910, which is arranged vertically. The yarn drum 300 is rotatably mounted on the first rotating frame 200 about a second axis 920, which is inclined. The central axis of the yarn drum 300 is coaxial with the second axis 920, and the yarn drum 300 is detachably mounted on the first rotating frame 200. The first driving mechanism 400 is mounted on the base 100 and drives the first rotating frame 200 and the yarn drum 300 to rotate relative to the base 100 about the first axis 910. The second driving mechanism 500 drives the yarn drum 300 to rotate relative to the first rotating frame 200 about the second axis 920. The yarn guide frame 600 is mounted on the base 100.

[0036] When the yarn balling machine is started, the first drive mechanism 400 drives the first rotating frame 200 and the yarn drum 300 to rotate around the first axis 910, and the second drive structure drives the yarn drum 300 to rotate relative to the first rotating frame 200 around the second axis 920. The yarn drum 300 pulls the yarn passing through the yarn guide frame 600 and winds it around the outer circumference of the yarn drum 300, gradually forming a yarn ball. After the yarn ball is wound, it can be detached from the yarn drum 300 along the central axis direction. Since the yarn drum 300 is detachable relative to the first rotating frame 200, different specifications of yarn drums 300 can be replaced to adapt to the production of yarn balls with different center hole diameters, thereby producing yarn balls of different sizes and specifications, improving the versatility of the yarn balling machine.

[0037] Specifically, the yarn guide 600 is located on one side of the yarn spool 300 in the horizontal direction.

[0038] In an embodiment, the second drive mechanism 500 includes a connecting shaft 510 and a second rotating frame 520. The second rotating frame 520 is rotatably connected to the first rotating frame 200 about a second axis 920. The connecting shaft 510 is arranged along the first axis 910 and fixedly connected to the base 100. The connecting shaft 510 is provided with a first gear portion 511. The second rotating frame 520 is provided with a second gear portion 521 around the second axis 920. The first gear portion 511 meshes with the second gear portion 521. The winding drum 300 is detachably connected to the second rotating frame 520. When the first drive mechanism 400 drives the first rotating frame 200 to rotate around the first axis 910, the first rotating frame 200 also drives the second rotating frame 520 and the winding drum 300 on it to rotate around the first axis 910. Since the connecting shaft 510 is fixed on the base 100, the first gear part 511 of the connecting shaft 510 meshes with the second gear part 521 of the second rotating frame 520, so that the second rotating frame 520 and the winding drum 300 on it can also rotate relative to the first rotating frame 200 around the second axis 920, so that the yarn can be wound relatively evenly around the outer circumference of the winding drum 300. The aforementioned second drive mechanism 500 utilizes the rotational power of the first rotating frame 200, the second rotating frame 520, and the winding drum 300 around the first axis 910 to drive the second rotating frame 520 and the winding drum 300 to rotate relative to the first rotating frame 200. This eliminates the need for an additional driver to individually drive the second rotating frame 520 and the winding drum 300 to rotate relative to the first rotating frame 200 around the second axis 920. The structure is relatively simple and saves manufacturing costs.

[0039] It is conceivable that in other embodiments, the second drive mechanism 500 can also have other structures. For example, the second drive mechanism 500 can be a geared motor, which is mounted on the first rotating frame 200. The output shaft of the geared motor is arranged along the second axis 920, and the cable reel 300 can be directly inserted into the output shaft of the geared motor, achieving a detachable connection between the two; or the output shaft of the geared motor is connected to the second rotating frame 520, and the cable reel 300 can be snapped onto the second rotating frame 520, achieving a detachable connection between the two. In both cases, the second drive mechanism 500 can drive the cable reel 300 to rotate relative to the first rotating frame 200 around the second axis 920.

[0040] Specifically, the first rotating frame 200 is provided with a rotating shaft hole, and the connecting shaft 510 passes through the rotating shaft hole. The first rotating frame 200 is rotatably connected to the connecting shaft 510 through a bearing, so that the first rotating frame 200 can rotate relative to the base 100.

[0041] In this embodiment, the cable reel 300 is provided with a retaining strip 310 around the second axis 920, and the second rotating frame 520 is provided with a retaining groove around the second axis 920, with the retaining strip 310 engaging in the retaining groove. The cable reel 300 rotates clockwise relative to the second rotating frame 520 around the second axis 920 to engage the retaining strip 310 into the retaining groove, thereby achieving assembly and connection between the two. When the cable reel 300 rotates counterclockwise relative to the second rotating frame 520, the retaining strip 310 can disengage from the retaining groove, thereby achieving disassembly and separation between the two. The above structure enables a detachable connection between the cable reel 300 and the second rotating frame 520, and is simple in structure and easy to implement.

[0042] In this embodiment, the width of the retaining strip 310 gradually increases circumferentially along the second axis 920. When the retaining strip 310 rotates into the retaining groove of the aforementioned cable reel 300, it can adaptively lock into a suitable width position, reducing the risk of loosening or separation. It should be understood that the width of the narrow end of the retaining strip 310 is A, the width of the wide end of the retaining strip 310 is B, and the width of the retaining groove is C, satisfying A < C < B. That is, the narrow end of the retaining strip 310 can enter the retaining groove first, and then the cable reel 300 can continue to rotate until the two are tightly fitted, achieving assembly and fixation.

[0043] It is conceivable that in other embodiments, the spool 300 may also be detachably connected to the second rotating frame 520 in other ways. For example, the spool 300 may be detachably installed on the second rotating frame 520 by means of screw fastening, and the two may be disassembled and separated by loosening the screws; or the spool 300 may be detachably installed on the second rotating frame 520 by means of plug-in connection.

[0044] In this embodiment, the first drive mechanism 400 includes a rotary driver 410 and a belt drive structure 420. The rotary driver 410 is driven by the belt drive structure 420 to the first rotating frame 200. Specifically, the belt drive structure 420 includes a belt and two pulleys. One pulley is mounted on the output shaft of the rotary driver 410, and the other pulley is mounted on the first rotating frame 200. The belt is wound around the two pulleys. The rotary driver 410 drives the first rotating frame 200 to rotate via the belt drive structure 420. When the yarn gets stuck between the spool 300 and the yarn guide 600, the first rotating frame 200 is difficult to rotate continuously. At this time, the belt can slip on the pulleys, reducing the risk of overloading the rotary driver 410 and thus reducing the risk of damage to the rotary driver 410.

[0045] Specifically, the rotary actuator 410 is an electric motor. It is conceivable that the rotary actuator 410 could also be other structures that output rotational power, such as an internal combustion engine, and those skilled in the art can choose according to actual needs.

[0046] It is conceivable that in some other embodiments, the first drive mechanism 400 may also be a motor in conjunction with a reduction gearbox, with the motor driving the first rotating frame 200 to rotate through the reduction gearbox. Those skilled in the art can make specific choices according to actual needs.

[0047] In this embodiment, a control module 700 and a foot switch are also included. The control module 700 is disposed on the base 100 and electrically connected to the rotary driver 410. The foot switch is electrically connected to the control module 700 and can control the opening and closing of the rotary driver 410. The control module 700 can adjust the rotation speed and / or direction of the rotary driver 410.

[0048] The control module 700 can adjust the rotation speed of the rotary driver 410 to adapt to different production speed requirements. The control module 700 can also adjust the direction of rotation of the rotary driver 410 to meet the winding direction requirements of different products, making it more flexible in use. Furthermore, the rotary driver 410 can be started and stopped via a foot switch, making the start-stop control of the yarn pilling machine more flexible and convenient for handling situations such as yarn jamming, breakage, or pilling during winding.

[0049] Specifically, the control module 700 includes a circuit board 710, an on / off button 720, a speed adjustment knob 730, and a direction adjustment button 740. Users can adjust the operating status of the yarn spinning machine through the control module 700 according to their own needs. The foot switch is connected to the foot pedal connector 110 of the base 100 via a wire, meaning the foot switch can also be detached from the base 100.

[0050] Specifically, the base 100 is also equipped with a power connector 120, which can be a USB type connector or a conventional connector for power supply, providing good versatility.

[0051] It is conceivable that in other embodiments, the control module 700 may also be a structure with control circuitry, such as a PLC or a microcontroller, used in conjunction with a touch screen to regulate the operating status of the yarn spinning machine.

[0052] In this embodiment, a locking mechanism 800 is also included. The yarn guide frame 600 includes a vertical rod portion 610 and a spiral rod portion 620. The vertical rod portion 610 is slidably disposed on the base 100 in the vertical direction, and the spiral rod portion 620 is located at the upper end of the vertical rod portion 610. The locking mechanism 800 is disposed between the base 100 and the vertical rod portion 610 and is used to lock or unlock the position of the vertical rod portion 610 relative to the base 100.

[0053] The yarn can be positioned and guided by the helical rod section. The yarn guide frame 600 is slidably connected to the machine base 100 via the vertical rod 610 to adjust the height of the helical rod 620, thereby allowing yarn balls of different sizes to be wound on the winding drum 300 along the second axis 920, resulting in a greater variety of yarn ball sizes. The locking mechanism 800 can lock or unlock the position of the vertical rod 610, facilitating the adjustment, movement, or maintenance of the yarn guide frame 600, making it more convenient to use.

[0054] In this embodiment, the base 100 has mounting holes along its vertical direction. The vertical rod 610 slides through the mounting holes. The locking mechanism 800 includes a threaded through hole and a threaded fastener. The threaded through hole is radially disposed in the base 100 and extends to the wall of the mounting hole. The threaded fastener is threadedly connected to the threaded through hole. When the threaded fastener is tightened, one end abuts against the vertical rod 610, fixing the position of the yarn guide 600 by friction. When the threaded fastener is loosened, it separates from the vertical rod 610, allowing the yarn guide 600 to slide up and down, thus locking or unlocking the yarn guide 600. The structure is relatively simple and the manufacturing cost is low.

[0055] It is understood that in other embodiments, the yarn guide 600 may also move up and down relative to the base 100 via a slide rail slider structure.

[0056] Specifically, the threaded fastener can be a screw, such as a handle screw, allowing the user to directly tighten it. It is conceivable that in other embodiments, the locking mechanism 800 can also be other structures. For example, the vertical rod 610 may have multiple position slots arranged along its length, and a spring and a plug-in block may be provided on the base 100. In the normal state, the spring drives the plug-in block to insert into one of the position slots, thereby locking the height of the yarn guide 600. When the user moves the plug-in block out of the current position slot, it unlocks, allowing the yarn guide 600 to slide up and down to adjust its position. Then, the user releases the plug-in block, causing the spring-driven plug-in block to insert into another position slot, re-locking the position of the yarn guide 600.

[0057] In this embodiment, the first rotating frame 200 is provided with a dynamic balance counterweight 210, which makes the first rotating frame 200 rotate more smoothly, reduces vibration and noise, improves the service life of the parts, and makes the tension of the wound yarn relatively uniform.

[0058] In this embodiment, the outer periphery of the yarn drum 300 is provided with a plurality of raised ribs 320. The raised ribs 320 extend along the direction of the second axis 920 and are evenly arranged around the second axis 920, which makes it easier for the yarn ball after winding to be pulled out and removed from the yarn drum 300 along the direction of the second axis 920.

[0059] Specifically, the end of the yarn drum 300 away from the first rotating frame 200 has a yarn-holding groove 330, which makes it easy for the yarn to be inserted and fixed in the yarn-holding groove 330 in the initial state, so that the yarn drum 300 can generate sufficient pulling force when rotating to pull the yarn on the yarn guide frame 600.

[0060] Specifically, the base 100 is equipped with a counterweight to make it more stable when placed on a desktop.

[0061] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

[0062] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
