Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example (b):
as shown in fig. 1, the utility model provides a bobbin winder reel fixing device, which comprises an installation shaft 1 which can be rotatably arranged on a bobbin winder, a reel 4 is inserted on the installation shaft 1, the rotation of the reel 4 is realized by a motor 6, namely, the motor 6 is installed on a mounting plate 5, the mounting plate 5 is installed on the bobbin winder, and finally the reel 4 is driven to rotate to realize the winding of yarn;
as shown in fig. 2, two cylindrical push sleeves 2 capable of moving in an axial direction (the axial direction in this embodiment refers to the axial direction of the mounting shaft 1) are arranged on the mounting shaft 1, wherein an external thread is formed on the outer peripheral wall of the mounting shaft 1, the two push sleeves 2 are slidably arranged on the mounting shaft 1, an adjusting nut 11 for pushing the push sleeves 2 to slide is assembled on the mounting shaft 1 through a thread, the two push sleeves 2 are connected through a plurality of plate springs 3 uniformly distributed along the circumferential direction, the plate springs 3 are abutted against the winding drum 4, so that the winding drum 4 is fixed, and a certain radian is provided in an initial state (i.e., in a state where the plate springs 3 are not stressed) of the plate springs 3;
further, with reference to fig. 3, one end of the plate spring 3 is rotatably disposed on one of the pushing sleeves 2, the other end of the plate spring 3 is rotatably disposed on the other pushing sleeve 2, the connection of the rotation is realized by the cooperation of the hinge seats 21 and the hinge shafts 31, namely, the hinge seats 21 are uniformly circumferentially distributed on the pushing sleeve 2, two ends of the plate spring 3 are symmetrically disposed with the hinge shafts 31, and the hinge shafts 31 are rotatably disposed on the hinge seats 21.
Further, in order to ensure the stability of the contact between the winding drum 4 and the plate spring 3, as shown in fig. 5, a plurality of arc-shaped grooves 41 corresponding to the plate springs 3 one by one are formed on the inner peripheral wall of the winding drum 4 (the center of the winding drum 4 in the prior art has a cylindrical hole, so the inner peripheral wall of the winding drum 4 in the present application refers to the inner peripheral wall of the cylindrical hole, as shown in fig. 6), the plate spring 3 is closely positioned in the arc-shaped grooves 41, the deepest part of the arc-shaped grooves 41 is slightly larger than the thickness of the plate spring 3, and the width of the arc-shaped grooves 41 is the same as the width of the; when the two push sleeves 2 move in opposite directions, the plate spring 3 deforms and then abuts against the arc-shaped groove 41, so that the rotation of the winding drum 4 relative to the mounting shaft 1 is limited, and along with the further movement of the push sleeves 2, the contact area between the plate spring 3 and the arc-shaped groove 41 is gradually increased by the deformation of the plate spring 3, and the contact stability is further improved; it should be noted that, when winding yarn, yarn needs to be pressed, so the elasticity of the plate spring 3 is larger than the pressure generated when pressing yarn (the pressure generated when pressing yarn is not too large), which avoids the large fluctuation of the winding drum 4 when rotating, in addition, the movement of the pushing sleeve 2 needs to be controlled in a reasonable range, if the pushing sleeve 2 is forced to be pushed continuously, the winding drum 4 (the winding drum 4 is generally made of plastic material) may deform, when in actual use, the pushing sleeve 2 is pushed by the adjusting nut 11, the plate spring 3 cannot be completely attached to the arc-shaped groove 41, when the rotating adjusting nut 11 is sensed to have large resistance (when the plate spring 3 is just attached to the arc-shaped groove 41), the plate spring 3 rotates several times, the contact area between the plate spring 3 and the arc-shaped groove 41 is increased, specifically, the operation can be flexibly performed in actual use, for example, the winding drum 4 can be pulled down by hand after adjustment, whether the winding drum is stable or not is judged, if the winding drum 4 slightly stirs, the winding drum generates larger vibration, the adjusting nut 11 can be rotated again to increase the contact area of the plate spring 3 and the arc-shaped groove 41, and the winding drum 4 can be stably wound; therefore, the specific rigidity of the plate spring 3 is not limited, and the plate spring 3 meeting the production requirement can be selected automatically in actual use.
Further, arc wall 41 and the surface that plate spring 3 contacted on, plate spring 3 and arc wall 41 contacted on all be provided with the hemispherical arch of a plurality of evenly distributed, the bellied setting has increased frictional force, and wherein bellied size should not be too big, as long as make plate spring 3 and arc wall 41 have rough sense can.
When the winding drum is used, the winding drum 4 is nested on the mounting shaft (namely sleeved on the two pushing sleeves 2), then the two pushing sleeves 2 are pushed to move in opposite directions by rotating the adjusting nut 11, so that the plate spring 3 is deformed and tightly propped against the arc-shaped groove 41 of the winding drum 4, and the winding drum 4 is further fixed, when the adjusting nut 11 is rotated, when the plate spring 3 is just tightly propped against the arc-shaped groove 41 by rotating the adjusting nut 11, the resistance of continuously rotating the adjusting nut 11 is increased, and in order to ensure the stability of the winding drum 4, the adjusting nut 11 is continuously rotated for a plurality of circles again, so that the contact area between the plate spring 3 and the arc-shaped groove 41 is increased; when the winding drum 4 is installed, the deformable characteristic of the plate spring 3 enables the plate spring 3 to adapt to the winding drum 4 with various inner diameters (the inner diameter refers to the inner diameter of a central cylindrical hole of the winding drum 4), and meanwhile, because the two push sleeves 2 can axially move, the position of the winding drum 4 on the installation shaft 1 can be adjusted, the winding drum 4 can further adapt to the winding drums 4 with different lengths, and finally the adaptability of the winding machine is improved.
It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
