Description

Technical Field

[0001] The utility model relates to the technical field of wire take-up machines, and in particular to a quick elastic wire drum structure applied to the wire take-up machine. Background Art

[0002] When winding the wire, it is usually necessary to wind the wire around the reel. In order to facilitate the rapid positioning and installation of the reel, an expansion shaft is added to the wire winding machine. For example, the utility model with the announcement number "CN221849707U" and the name "Hand-tightened internal expansion shaft" discloses a hand-tightened internal expansion shaft, which includes a main shaft body, a tile, a floating rod, a movable connecting rod, a sliding connecting rod, a toothed slider, a rotating sleeve and a screw. The floating rod is located in the axial groove of the main shaft body, the tail end of the movable connecting rod is connected to the front end of the floating rod, and the front end is hinged on the axial groove. The front end of the sliding connecting rod is hinged to the tail end of the floating rod, and the tail end is movable in the axial groove. The toothed slider is movable in the axial groove, and the rotating sleeve is rotatably sleeved on the tail end of the main shaft body by a screw. When adjustment is required, the rotating sleeve is twisted to force the toothed slider to move forward or backward in the axial groove, and the floating rod is driven to float or descend through the sliding connecting rod to achieve expansion or contraction, thereby fixing the reel. However, during adjustment, the operator needs to turn the rotating sleeve several times before removing the reel; after installing the new reel, the operator has to continue turning the rotating sleeve several times, which is time-consuming and labor-intensive, easily causing fatigue, and relatively low work efficiency.

[0021] For example, see Figures 1 to 5 The present embodiment provides a quick elastic cable drum structure, which includes a bearing seat 1, a rotating spindle 2, a fixed top cone 3, a movable top cone 4, a pull rod 5, an elastic component 6, a linear drive device 7, a return spring 8 and a pin 9, and the rotating spindle 2 is arranged on the bearing seat 1.

[0022] The rotating spindle 2 is provided with an axial hole extending axially therethrough. The fixed top cone 3 is fixedly mounted on the rotating spindle 2. The fixed top cone 3 includes a fixed disc 31, a linkage plate 32, and a linkage rod 33. The middle portion of the linkage plate 32 is fixed to the fixed disc 31, and both ends are provided with adjustment slots extending along the longitudinal direction of the sides thereof. The linkage rod 33 is mounted on the adjustment slots. The provision of the adjustment slots allows the position of the linkage rod 33 to be flexibly adjusted, thereby enhancing the adaptability and flexibility of the structure. To accommodate wire reels 10 of different specifications, the spacing between the two linkage rods 33 can be adjusted accordingly based on the size of the wire reel 10 so that they are aligned and inserted into the linkage holes on the wire reel 10.

[0023] The front end of the rotating main shaft 2 is symmetrically provided with a number of radial holes 21. In this embodiment, the number of radial holes 21 is six. The reset spring 8 and the pin 9 are arranged in the radial hole 21, and the reset spring 8 can push the pin 9 back into the radial hole 21 in a natural state; preferably, a hemispherical head is provided at one end of the pin 9, and the other end is radially reduced to form a protruding portion, and the reset spring 8 is sleeved on the protruding portion. The hemispherical head makes the pin 9 fit more smoothly with the conical head and is not easy to get stuck. A cover plate 22 is provided on the opening of the radial hole 21, and an opening is provided on the cover plate 22 for the protruding portion to extend. The reset spring 8 is limited by the cover plate 22, and at the same time, dust and debris are effectively prevented from entering the radial hole 21, thereby protecting the pin 9 and the reset spring 8 from damage.

[0024] The movable top cone 4 is movably mounted on the front end of the rotating main shaft 2. To facilitate the installation of the movable top cone 4, the front end of the rotating main shaft 2 is radially reduced to form a sleeve portion, and the six radial holes 21 are symmetrically distributed on the sleeve portion.

[0025] The pull rod 5 is movably located in the shaft hole, and has a conical head 51 at its front end that can push the pin 9 out of the radial hole 21 and press against the movable top cone 4 when it moves backward. Preferably, a slot that matches the pin 9 is provided on the inner hole wall of the movable top cone 4. When the pin 9 is snapped into the slot, the fit is good, and the movable top cone 4 can be driven to move axially to lock the wire drum 10.

[0026] The elastic component 6 is arranged on the rotating main shaft 2 and can push the pull rod 5 to move backward; specifically, the tail end of the rotating main shaft 2 is provided with a concave cavity 23, and the tail end of the pull rod 5 passes through the concave cavity 23 and is provided with a clamp 52. The elastic component 6 is located in the concave cavity 23, and one end presses on the inner wall of the concave cavity 23, and the other end presses on the clamp 52. The elastic force of the elastic component 6 enables the pull rod 5 to continue to move backward, and the fixing effect of the wire drum 10 is good. The elastic component 6 is preferably a plurality of overlapping butterfly gaskets, and the required number of butterfly gaskets can be flexibly stacked according to the required elastic force, and the elastic force output is uniform and stable.

[0027] The driving component of the linear drive device 7 is connected to the pull rod 5 and can push the pull rod 5 to move axially. In this embodiment, the linear drive device 7 is preferably a cylinder that can quickly drive the pull rod 5 forward and backward to achieve rapid tensioning and loosening of the cable drum 10. In other embodiments, the linear drive device 7 can also be an oil cylinder or a linear motor.

[0028] During operation, when the reel needs to be changed, the linear drive device 7 pushes the pull rod 5 forward, and under the elastic force of the return spring 8, the push pin shaft 9 retracts into the radial hole 21. At this time, the movable top cone 4 can be easily removed, which facilitates the rapid replacement of the reel 10.

[0029] When loading the reel, lift the reel 10 until its hole is aligned with the rotating spindle 2, and insert the rotating spindle 2 into the hole of the reel 10, and continue to push the reel 10 to fit tightly against the fixed top cone 3. At this time, the linkage rod 33 on the fixed top cone 3 is just inserted into the linkage hole 101 on the reel 10. Ensure that the rotating spindle 2 drives the reel to rotate synchronously through the fixed top cone 3. Then install the movable top cone 4, control the linear drive device 7 to retract and pull the pull rod 5 backward, and force the pin shaft 9 to extend through the conical head 51 to cooperate with the movable top cone 4, and drive the movable top cone 4 to press toward one side of the fixed top cone 3, so that the movable top cone 4 can close relative to the fixed top cone 3, clamping and locking the reel, and the elastic component 6 continuously maintains a backward pulling force, effectively maintaining the clamping state, and achieving a good loading effect. The entire operation process is simple, fast, and time-saving and labor-saving.
