Description

Technical Field

[0001] This utility model relates to the field of combing machine technology, and in particular to a quick-release and disassembly mechanism for the gears of a combing machine drive shaft. Background Technology

[0002] Currently, the movement of the separating rollers in a combing machine is mainly achieved through a transmission structure such as a cam, main shaft, and sprocket. For example, Chinese utility model patent with authorization announcement number CN219099422U discloses a gear transmission shaft structure. In this structure, the main shaft and transmission components such as gears, sprockets, and cams are connected through the mutual cooperation of spline grooves and splines. A locking component is provided in the spline groove, which can pass through the spline groove and abut against the spline. Usually, multiple splines are provided on a main shaft. The main shaft drives the splines, which in turn drive the gears, sprockets, and cams through the spline groove.

[0003] Current technical problems: In the above scheme, each transmission component and the spindle are set independently. The advantage of this structure is that the installation method is flexible. Only one transmission component on the spindle can be installed or removed individually. However, when multiple transmission components need to be installed or removed at the same time, all transmission components can only be removed in sequence, so the efficiency is low. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a quick gear disassembly and assembly mechanism for the drive shaft of a combing machine, so as to solve the technical problem that the existing combing machine drive shaft requires separate operation for each drive component when installing and disassembling multiple drive components, resulting in low efficiency.

[0005] To achieve the above objectives, this utility model provides a quick-release and assembly mechanism for the gears of a combing machine drive shaft, comprising:

[0006] The main shaft and at least one spline provided on the circumferential surface of the main shaft for adapting to the spline groove of the transmission component;

[0007] A rotating shaft is rotatably connected to an inner cavity formed in the main shaft. The main shaft has a sliding groove on its outer circumferential surface that is adapted to the shape of a spline, and the sliding groove is connected to the inner cavity.

[0008] A drive component connected to and rotating with the shaft;

[0009] A driven component connected to the spline is used to convert the rotational motion of the driving component into its own linear motion, thereby driving the spline to extend and retract into the spindle through the slide groove, so that the spline can connect and disconnect from the spline groove.

[0010] A self-locking structure for limiting the rotational movement of the shaft relative to the main shaft.

[0011] As a preferred embodiment of this utility model, the driving component is a gear connected to the rotating shaft, and the driven component is a rack adapted to the gear. One end of the rack is connected to the inner side of the spline. By rotating the rotating shaft, it can drive the gear and the rack to mesh, thereby driving the spline connected to the rack to move linearly along the slide groove.

[0012] As a preferred embodiment of this utility model, the self-locking structure includes:

[0013] A rotating body connected at one end to the rotating shaft, the rotating body having a through threaded groove;

[0014] A threaded rod with one end threadedly connected to the threaded groove, wherein one end of the threaded rod engages with a snap-fit ​​groove formed in the inner cavity of the spindle.

[0015] As a preferred technical solution of this utility model, the threaded rod is provided with a snap-fit ​​connector at one end that is adapted to the shape of the snap-fit ​​groove. The snap-fit ​​connector and the snap-fit ​​groove are engaged with each other to restrict the rotating body and the rotating shaft from rotating relative to the main shaft around the axis.

[0016] As a preferred embodiment of this utility model, the threaded rod is provided with a rocker arm at the end away from the snap-fit ​​connector, and the rocker arm is slidably engaged with a movable groove formed on the surface of the spindle.

[0017] As a preferred embodiment of this utility model, the spindle has a port at one end near the rotating body, the port being used to allow the rotating body, the shaft and the gear to be removed from the inner cavity of the spindle.

[0018] As a preferred embodiment of this utility model, the disassembly and assembly mechanism further includes two support structures arranged relative to the main shaft for supporting the main shaft, the support structures including:

[0019] Fixed bracket;

[0020] A movable bracket is hinged to the fixed bracket, and the movable bracket and the fixed bracket have through grooves at their contact points that are adapted to the cross-sectional shapes of the two ends of the main shaft;

[0021] The first bolt is used to secure the fixed bracket and the movable bracket.

[0022] As a preferred embodiment of this utility model, the supporting structure further includes:

[0023] A bearing groove is formed at the point where the movable bracket and the fixed bracket come into contact;

[0024] A ball bearing is disposed in the bearing groove, and the ball bearing is used to connect the end of the spindle.

[0025] As a preferred embodiment of the present invention, the support structure further includes a pad located at the bottom of the fixed bracket, and a second bolt for connecting the pad and the fixed bracket is provided between the pad and the fixed bracket.

[0026] The beneficial effects of this utility model are as follows: By opening an inner cavity inside the main shaft and rotating a shaft within the inner cavity, and setting a driving component and a driven component on the shaft and spline respectively, this utility model can enable the driving component and the driven component to cooperate by rotating the shaft in a first direction or a second direction. The driven component converts the rotational motion of the driving component into its own linear motion, thereby driving the spline to connect and disconnect with the spline groove inside the transmission component. This allows for the batch installation and disassembly of multiple transmission components on the main shaft with high efficiency. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0035] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, a quick-release gear assembly / disassembly mechanism for a combing machine drive shaft includes: a main shaft 7 and at least one spline 10 on the circumferential surface of the main shaft 7 for adapting to the spline groove of a transmission component; a rotating shaft 13 rotatably connected to an inner cavity formed in the main shaft 7, the main shaft 7 having a groove 11 on its outer circumferential surface adapted to the shape of the spline 10, the groove 11 communicating with the inner cavity; a drive component connected to the rotating shaft 13 and capable of rotating with it; a driven component connected to the spline 10, the driven component converting the rotational motion of the drive component into its own linear motion, thereby driving the spline 10 to extend and retract into the main shaft 7 through the groove 11, so that the spline 10 connects and disengages from the spline groove; and a self-locking structure for limiting the rotational motion of the rotating shaft 13 relative to the main shaft 7.

[0037] The above technical solution enables the batch disassembly and installation of multiple transmission components on the spindle 7. When it is necessary to disassemble the transmission components on the spindle 7, the self-locking structure releases the restriction on the rotational movement of the rotating shaft 13 relative to the spindle 7. The rotating shaft 13 is rotated in the first direction to drive the drive component connected to it to rotate synchronously. The drive component cooperates with the driven component, and the driven component converts the rotational movement of the drive component into its own linear movement, causing the driven component to drive the spline 10 to retract into the spindle 7 through the slide groove 11. The spline 10 is disengaged from the spline groove of the transmission component, thereby allowing the transmission component to be removed from the spindle 7. When it is necessary to install... When installing the transmission component, place it on the corresponding position on the surface of the main shaft 7, ensuring that the spline 10 and the slide groove 11 are aligned with the spline groove inside the transmission component. Rotate the shaft 13 in a second direction opposite to the first direction to drive the drive component connected to it to rotate synchronously. The drive component and the driven component cooperate to drive the spline 10 to extend out of the main shaft 7 through the slide groove 11. The spline 10 engages with the spline groove of the transmission component, thus completing the installation. After installation, lock the shaft 13 with a self-locking structure to prevent the shaft 13 from rotating relative to the main shaft 7 due to accidental contact, ensuring a stable connection between the spline 10 and the spline groove of the transmission component.

[0038] like Figure 3 and Figure 4 As shown, in this embodiment, the driving component is a gear 14 connected to the rotating shaft 13, and the driven component is a rack 12 adapted to the gear 14. One end of the rack 12 is connected to the inner side of the spline 10. By rotating the rotating shaft 13, it can drive the gear 14 to mesh with the rack 12, thereby driving the spline 10 connected to the rack 12 to move linearly along the slide groove 11. One end of the rotating shaft 13 is rotatably engaged with the end hole 15 opened at one end of the inner cavity of the main shaft 7. A limit baffle 16 is provided on the surface of the rotating shaft 13. The limit baffle 16 is used to prevent the rotating shaft 13 from moving along its axial direction.

[0039] The above technical solution can convert the rotational motion of the rotating shaft 13 into the linear motion of the spline 10. When in use, when the rotating shaft 13 rotates, it will drive the gear 14 connected to it to rotate synchronously. The gear 14 meshes with the rack 12, thereby driving the spline 10 connected to the rack 12 to make linear motion along the slide groove 11.

[0040] like Figure 3 and Figure 5As shown, in this embodiment, the self-locking structure includes: a rotating body 17 connected to the rotating shaft 13 at one end, the rotating body 17 having a through threaded groove 18; a threaded rod 19 threadedly connected to the threaded groove 18 at one end, one end of the threaded rod 19 engaging with a snap-fit ​​groove 21 in the inner cavity of the main shaft 7; the threaded rod 19 having a snap-fit ​​connector 20 at one end that matches the shape of the snap-fit ​​groove 21, the snap-fit ​​connector 20 engaging with the snap-fit ​​groove 21 to restrict the rotating body 17 and the rotating shaft 13 from rotating relative to the main shaft 7 around the axis;

[0041] The above technical solution can restrict the rotation of the rotating shaft 13 relative to the main shaft 7. When the rotating shaft 13 rotates to the required position, the threaded rod 19 is rotated along the first direction to engage with the threaded groove 18, causing the snap-fit ​​connector 20 to be inserted into the snap-fit ​​groove 21 in the inner cavity of the main shaft 7. This restricts the rotational freedom of the rotating body 17. Since the rotating body 17 and the rotating shaft 13 are fixedly connected, the rotating shaft 13 cannot rotate relative to the main shaft 7. Conversely, when it is necessary to release the rotation restriction of the rotating shaft 13, the threaded rod 19 is rotated along the second direction opposite to the first direction, which can disengage the snap-fit ​​connector 20 from the snap-fit ​​groove 21, thereby allowing the rotating body 17 and the rotating shaft 13 to rotate. Preferably, there are two snap-fit ​​grooves 21 to engage with the snap-fit ​​connector 20, corresponding to the two states of the spline 10 being connected to and disconnected from the spline groove.

[0042] like Figure 3 and Figure 5 As shown, in this embodiment, the threaded rod 19 is provided with a rocker arm 22 at the end away from the snap-fit ​​connector 20, and the rocker arm 22 is slidably engaged with the movable groove 23 opened on the surface of the spindle 7.

[0043] The above technical solution allows for easy rotation of the threaded rod 19. In use, the rocker arm 22 can be rotated to drive the threaded rod 19 to rotate, and the threaded rod 19 can extend and retract in conjunction with the threaded groove 18 in the rotating body 17.

[0044] like Figure 3 and Figure 5 As shown, in this embodiment, the spindle 7 has a port 24 at one end near the rotating body 17. The port 24 is used to allow the rotating body 17, the shaft 13 and the gear 14 to be taken out from the inner cavity of the spindle 7.

[0045] The above technical solution allows for easy removal of the rotating body 17, the rotating shaft 13, and the gear 14 from the inner cavity of the main shaft 7. When disassembly is required, the rocker arm 22 is rotated so that the threaded rod 19 at one end disengages from the threaded groove 18 in the rotating body 17, and the threaded rod 19 is pulled out from the movable groove 23 on the surface of the main shaft 7. The rotating body 17, the rotating shaft 13, and the gear 14 can then be removed from the port 24 of the main shaft 7, facilitating disassembly and maintenance.

[0046] like Figure 1and Figure 2 As shown, in this embodiment, the disassembly and assembly mechanism further includes two support structures for supporting the main shaft 7, which are arranged relative to the main shaft 7. The support structures include: a fixed bracket 2; a movable bracket 4 hinged to the fixed bracket 2, wherein the movable bracket 4 and the fixed bracket 2 have through grooves 5 at their mating points that are adapted to the cross-sectional shapes of the two ends of the main shaft 7; a first bolt 6 for fixing the fixed bracket 2 and the movable bracket 4; the support structure further includes: a bearing groove 8 formed at the mating point of the movable bracket 4 and the fixed bracket 2; and a ball bearing 9 disposed in the bearing groove 8, wherein the ball bearing 9 is used to connect the end of the main shaft 7.

[0047] The above technical solution allows the main shaft 7 to be easily fixed on the mounting surface of the combing machine. By setting the fixed bracket 2 and the movable bracket 4, the two can support the end of the main shaft 7. Ball bearings 9 are set at corresponding positions of the fixed bracket 2 and the movable bracket 4, which can effectively reduce the coefficient of friction between the main shaft 7 and the fixed bracket 2 and the movable bracket 4, and prevent component wear. At the same time, the fixed bracket 2 and the movable bracket 4 are connected by a hinge, which allows the movable bracket 4 to be rotated relative to the fixed bracket 2, thereby removing the main shaft 7 and the ball bearings 9 from the fixed bracket 2.

[0048] like Figure 1 and Figure 2 As shown, in this embodiment, the support structure also includes a pad 1 disposed at the bottom of the fixed bracket 2, and a second bolt 3 for connecting the pad 1 and the fixed bracket 2 is provided between the pad 1 and the fixed bracket 2.

[0049] The above technical solution allows for easy connection of the fixed bracket 2 to the combing machine. By setting the pad 1, it can fit against the mounting surface of the combing machine. The second bolt 3 can detachably connect the pad 1 to the mounting surface of the combing machine, making it easy to disassemble and replace.

[0050] Working principle: When it is necessary to disassemble the transmission component on the main shaft 7, rotate the threaded rod 19 to engage with the threaded groove 18 in the rotating body 17, thereby disengaging the snap-fit ​​connector 20 from the snap-fit ​​groove 21. This allows the rotating body 17 and the rotating shaft 13 to rotate. Rotating the rotating shaft 13 in the first direction causes the gear 14 connected to it to rotate synchronously. The gear 14 meshes with the rack 12, and the rack 12 converts the rotational motion of the gear 14 into its own linear motion. This causes the rack 12 to drive the spline 10 to retract into the main shaft 7 through the slide groove 11. The spline 10 disengages from the spline groove of the transmission component, thereby allowing the transmission component to be removed from the main shaft 7.

[0051] When the transmission component needs to be installed, place the transmission component on the corresponding position on the surface of the main shaft 7, ensuring that the spline 10 and the slide groove 11 are aligned with the spline groove inside the transmission component. Rotate the shaft 13 in a second direction opposite to the first direction, so that the shaft 13 drives the gear 14 connected to it to rotate synchronously. The gear 14 meshes with the rack 12, causing the spline 10 to extend out of the main shaft 7 through the slide groove 11. The spline 10 engages with the spline groove of the transmission component, thus completing the installation. After installation, rotate the threaded rod 19 in the opposite direction to make it engage with the threaded groove 18, causing the snap-fit ​​connector 20 to be inserted into the snap-fit ​​groove 21 inside the main shaft 7. This restricts the rotational freedom of the rotating body 17. Since the rotating body 17 and the shaft 13 are fixedly connected, the shaft 13 cannot rotate relative to the main shaft 7, preventing the shaft 13 from rotating relative to the main shaft 7 due to accidental contact, and ensuring a stable connection between the spline 10 and the spline groove of the transmission component.
