Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a bobbin core and bobbin case rotary pressing cover of a bobbin core and bobbin case unwinding machine. Background Art

[0002] When the current bobbin and bobbin case unwinding machine is working, whether it is extracting the remaining thread wound on the bobbin or winding new thread onto the bobbin, it is necessary to provide the bobbin and bobbin case with circumferential rotation support with axial limit constraints. To achieve this function, the applicant has developed two generations of products, including:

[0003] First-generation product: Chinese patent CN202311808506.0 discloses a fully automatic winding and thread-removing platform for the bobbin core and bobbin case of a textile machine, which is equipped with a power control system to provide the manipulator with displacement power and positioning control in the XY horizontal plane above the base plate. The wire inlet end of the fully automatic winding and thread-removing platform is equipped with a clamping and feeding device, and the fully automatic winding and thread-removing platform is equipped with a shearing and breaking device connected to the wire outlet end of the clamping and feeding device. The platform uses the power control system to cooperate with the manipulator's own Z-axis lifting control to achieve precise positioning of the manipulator in three-axis displacement above the base plate, which is convenient for the manipulator to locate the thread end hanging position; the clamping and feeding device realizes electric "braking", manual damping adjustment, and electric tension adjustment during the wire feeding process, which is convenient for the manipulator of the fully automatic winding and thread-removing platform to clamp the wire end when delivering the wire; the shearing and breaking device clamps and positions the cut silk thread ends, which is convenient for the manipulator of the fully automatic winding and thread-removing platform to grasp the broken silk thread ends.

[0004] This product solves a problem from scratch, that is, it uses an automated device (a motor drives the locking arm to flip and lock the bobbin case) to replace manual axial limiting and circumferential rotation support of the bobbin case. However, during actual use, the applicant found that as the bobbin core and bobbin case rotate at high speed to wind the thread, the bobbin case will jump and transmit upward vibration force to the locking arm, and the motor is always powered and outputs force when the bobbin case is positioned. On the one hand, this design will cause the motor to be in a "held" state after the bobbin core and bobbin case are positioned, reducing the service life of the motor. On the other hand, when the bobbin case rotates at a fast speed and the vibration force is large, it will resist the motor output force and cause axial displacement, resulting in failure of bobbin case positioning.

[0005] Second-generation product: Chinese patent CN202421860424.0 discloses a dewinding positioning actuator for a bobbin winding machine. This positioning actuator is installed on a fully automatic bobbin winding and dewinding platform. The positioning actuator includes a base plate, a dewinding shaft seat, a vertical positioning arm, a horizontal positioning arm, a dewinding unit, and a vacuum tube. The base plate is vertically penetrated and rotatably connected to a dewinding shaft seat that axially supports the bobbin. The base plate is vertically tilted and connected to a vertical positioning arm that axially engages and positions the bobbin. The base plate is also horizontally connected to a horizontal positioning arm that adjusts contact with the circumferential outer wall of the bobbin. The dewinding unit is rotatably connected to the base plate and rotates synchronously with the dewinding shaft seat in the same direction. The vacuum tube is fixed to one side of the base plate to absorb and remove excess thread wrapped around the bobbin. This device can automatically identify and position the bobbin, automatically remove excess thread, and automatically position and wind new thread, thereby solving the problem of low efficiency of existing manually assisted dewinding and winding. It has a simple structure and is easy to implement.

[0006] This product solves the problem of going from having to better, that is, on the basis of the first generation product, a magnetic attraction structure is added to the lower part of the locking arm, and the fitting contact between the magnets is used as the downward contact of the locking arm, and the attraction between the magnets is used to resist the axial vibration force of the bobbin core and bobbin case when the bobbin core and bobbin case rotate. This design solves the problem that the motor must always work when the locking arm is locked and positioned. After the locking arm is axially positioned by relying on the attraction between the magnets, the motor power supply can be disconnected, thereby improving the service life of the motor; however, the problem with this product is that the position of the magnets is difficult to control and needs to be adjusted frequently, and the attraction between the magnets will also change with the distance between the two. When the bobbin core and bobbin case axially jump to resist the attraction between the magnets, the restraining force applied to the bobbin core and bobbin case by this attraction is also not fixed. When the jumping force is greater than the attraction, it will also cause the bobbin case positioning to fail.

[0007] In summary, the applicant has researched and designed the third generation product of the present utility model to solve the problems existing in the first two generations of products on the basis of realizing the axial limit constraint and circumferential rotation support functions of the bobbin core and bobbin case.

[0023] The following describes in detail embodiments of the utility model. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the utility model and are not to be construed as limiting the utility model.

[0024] The utility model discloses a bobbin core and bobbin case rotary pressing cover of a bobbin core and bobbin case unwinding machine, which is snap-fitted and positioned on the axial end surface of the bobbin case rotatably supported on a swivel seat; the rotary pressing cover comprises a base 6, a snap-fitting force arm 2, a transmission force arm 3, a main force arm 4 and a motor 5, wherein the motor is fixedly arranged on one side of the base, and the snap-fitting force arm and the main force arm are hingedly connected on the top surface of the base; the power input end of the main force arm is fixedly connected to the power output end of the motor, and the power output end of the main force arm transmits force in one direction and is hingedly connected to the transmission force arm; the power output end of the transmission force arm is hingedly connected to the middle section of the snap-fitting force arm.

[0025] Preferably, an upwardly protruding limit block 8 is formed on the upper part of the power output end of the main force arm; a recessed limit groove 9 is provided on the upper part of the force input end of the transmission force arm, and the groove wall of the limit groove is supported and cooperated with the limit block to limit the maximum rotation angle of the lower surface of the main force arm and the lower surface of the transmission force arm.

[0026] Preferably, the power output end of the locking force arm is rotatably sleeved with a rotary cover 1, which cooperates with the rotary seat of the bobbin core and bobbin case unwinding machine to be vertically limited and clamped and rotatably supports the bobbin case on a horizontal plane.

[0027] In order to more clearly describe the specific implementation of the present invention, an embodiment is provided below:

[0028] The utility model discloses a bobbin core and bobbin case rotary pressing cover of a bobbin core and bobbin case winding machine. Figure 1As shown, two pairs of hinged seats 7 are fixed on the base, and the two hinged seats are arranged one in front and one behind in the X-axis direction. The pin on the front hinged seat is rotated to connect the locking arm, and the pin on the rear hinged seat is rotated to connect the active arm.

[0029] Clasp arm raised posture, such as Figure 2 and Figure 4 As shown, in the lifting posture, the base, the locking arm, the transmission arm, and the main force arm respectively constitute the four sides of the quadrilateral structure. The quadrilateral structure is unstable. When the motor applies a turning force to the main force arm, the transmission arm and the locking arm will also rotate synchronously until the rotating cover at the output end of the locking arm is locked on the bobbin case, that is, the locking posture of the locking arm, as shown in FIG. Figure 3 and Figure 5 As shown, in the buckling posture, the active force arm and the transmission force arm form a straight line, which forms a stable triangle structure with the base and the buckling force arm. When the force output end of the buckling arm receives Figure 3 When the counterclockwise rotational force (i.e., the axial jump force caused by the high-speed rotation of the bobbin core and bobbin case) is applied, this force will be transmitted by the locking arm to the straight line formed by the transmission arm and the main force arm, and then converted into a compressive force on this straight line between the transmission arm and the main force arm. After the locking arm is positioned, the motor can be powered off, and the locking arm's counterclockwise rotation is blocked by the self-locking principle of the mechanical structure described above. When the locking arm changes from the locked to the raised position, it is only necessary to control the motor to drive the main force arm to rotate counterclockwise. The main force arm drives the transmission arm, and the transmission arm drives the locking arm to rotate counterclockwise synchronously.

[0030] Finally, all the unmentioned parts of the utility model adopt mature products and mature technical means in the existing technology.
