Description

Technical Field

[0001] The utility model relates to a deflector, and specifically designs a deflection structure and a linear deflector which can reduce the volume and have no delay. Background Art

[0002] The wire deflector is mainly used to allow wires to pass through a deflection part, and through the swing of the deflection part, the input direction of the wires can be changed, so that the wires can form different braided shapes. The existing wire deflector mainly uses a motor to drive the deflection part to swing, so as to achieve the effect of the wire input direction. However, the existing structure that uses a motor to drive the deflection part to swing is heavier and has a larger overall volume. It takes up more space when installed on the machine and cannot be designed to be smaller and lighter. At the same time, when the forward and reverse rotation of the motor is used to drive the deflection part to swing back and forth, there will be a delay due to the change in the direction of the motor, which makes the entire wire supply not smooth, and further improvement is necessary.

[0036] The utility model provides a one-line deflector composed of a deflection structure. Please refer to Figure 1 As can be seen from the figure, the wire deflector of the utility model can be installed on a machine platform to allow a wire B to pass through and change the input direction of the wire B, such as Figure 1 As shown, the thread deflector of the present invention is installed on a machine platform of a knitting machine, but the thread deflector of the present invention is not limited to being installed on a knitting machine.

[0037] See also Figures 1 to 3 The deflection structure of the utility model includes a deflection member 20 and a magnetic coil 30, and the deflection member 20 and the magnetic coil 30 are arranged on a deflection seat 10 mainly included in the wire deflector, wherein the deflection seat 10 is used to be fixedly combined on a machine platform so that at least one hook A corresponds to the deflection member 20.

[0038] In this embodiment, a connecting plate 12 is provided on one side surface of the deflection seat 10, and a plurality of connecting holes 122 are provided on the connecting plate 12, so that the deflection seat 10 can be fixedly connected to the machine by means of fixing parts such as bolts passing through the machine and screwing into the connecting holes 122 on the connecting plate 12. In addition, the connecting holes 122 on the connecting plate 12 can also be a perforated form, so that the fixing parts can also be combined with the bolts after passing through the connecting holes 122 on the connecting plate 12, so that the deflection seat 10 can be fixedly connected to the machine. In addition, the deflection seat 10 can also be fixed to a connecting part, and then fixed to the machine through the connecting part.

[0039] The deflection member 20 can be set on the deflection seat 10 in a deflection manner, wherein a deflection groove 13 can be recessed on the bottom surface of the deflection seat 10 adjacent to the connecting piece 12, and the deflection member 20 is set in the deflection groove 13. The deflection member 20 mainly includes a seat body 22, on which a deflection shaft 222 rotatably connected to the deflection seat 10 is convexly provided, and at least one threading hole 24 passing through the seat body 22 is provided, so that the wire B passes through it and is guided by at least one hook A. The deflection member 20 deflects relative to the deflection seat 10 with the deflection shaft 222 as the axis, so that the threading hole 24 changes the corresponding at least one hook A.

[0040] The axial direction of the threading hole 24 may be parallel or non-parallel to the axial direction of the yaw shaft 222, and the at least one threading hole 24 may be directly and integrally provided on the base body 22, or at least one through hole 25 may be provided on the base body 22, and a threading sleeve 26 may be provided in each through hole 25, and the threading hole 24 may be provided to pass through the threading sleeve 26.

[0041] The friction coefficient of the surface of each threading sleeve 26 is lower than that of the base 22 , and the hardness of the threading sleeve 26 is higher than that of the base 22 .

[0042] The friction coefficient of the surface of each threading sleeve 26 can be determined by material selection, the pore size of each threading sleeve 26 surface and the pore density of each threading sleeve 26 surface. Preferably, each threading sleeve 26 can be made of ceramic material to prevent the wire B from directly rubbing against the seat body 22 and breaking when passing through the threading hole 24. In this embodiment, two threading holes 24 are respectively disposed on both sides of the deflection shaft 222.

[0043] At least one magnetic member 28 is disposed at any part of the deflection member 20, and the two ends of the magnetic member 28 are respectively an N magnetic pole and an S magnetic pole, and the extension direction of the N magnetic pole and the S magnetic pole is perpendicular to the axis. In this embodiment, the magnetic member 28 is embedded in the bottom surface of the base 22 of the deflection member 20 and exposed on a side of the base 22 that is different from the connecting piece 12, and the N magnetic pole and the S magnetic pole at the two ends of the magnetic member 28 correspond to the two threading holes 24 respectively.

[0044] The magnetic coil 30 is disposed beside the deflection member 20 and at a position corresponding to the magnetic member 28. The magnetic coil 30 is connected to a power source of a fixed machine through an electric wire to provide the power required by the magnetic coil 30. The magnetic coil 30 generates a magnetic field due to receiving power, and generates a repulsive or attractive reaction with the magnetic poles at both ends of the magnetic member 28, so that the deflection member 20 rotates relative to the deflection seat 10 with the deflection shaft 222 as the axis. In this way, the swing of the deflection member 20 is deliberately regulated by adjusting the magnetic field formed by the magnetic coil 30.

[0045] In this embodiment, the magnetic coil 30 is disposed in the pendulum seat 10, and a receiving groove 16 is recessed at a position adjacent to the pendulum groove 13 on the pendulum seat 10, and the magnetic coil 30 is received in the receiving groove 16, and then an upper cover 14 is provided on the pendulum seat 10 to cover the magnetic coil 30 and the receiving groove 16, so that the magnetic coil 30 is closed and received in the pendulum seat 10.

[0046] Furthermore, a limiting shaft 29 is protruded from the seat body 22 of the deflection member 20, and the end of the limiting shaft 29 is arranged toward the connecting plate 12, and the limiting shaft 29 can be displaced as the deflection member 20 swings. The deflection seat 10 includes a limiting hole 124 for the limiting shaft 29 to extend into, and both ends of the limiting hole 124 extend along a displacement direction of the limiting shaft 29 to limit the displacement range of the limiting shaft 29, so as to limit the rotation angle of the deflection member 20 relative to the deflection seat 10 with the deflection shaft 222 as the axis.

[0047] The mechanical properties of the inner wall formed by the limiting shaft 29 and / or the limiting hole 124 are better than those of the deflection seat 10 and / or the connecting piece 12. The mechanical properties include tensile strength, impact strength, hardness, elongation at break, shear strength, and compression strength, etc., which are related to resistance to external forces.

[0048] In this embodiment, the limiting shaft is protrudingly arranged on a side of the deflection member 20 corresponding to the connecting plate 12, and a limiting hole 124 is provided on the connecting plate 12 for the limiting shaft 29 to extend into. The limiting hole 124 can be square, and the mutual cooperation between the limiting shaft 29 and the limiting hole 124 can be used to limit the range of rotation and deflection of the deflection member 20 relative to the deflection seat 10.

[0049] Further, the area where the limiting shaft 29 and the connecting piece 12 form the limiting hole 124 can be made of heat-treated steel. This can improve the structural rigidity of the limiting shaft 29 and the connecting piece 12 to prevent the limiting shaft 29 from breaking in the limiting hole 124 due to resisting knocking.

[0050] When operating this utility model, please refer to Figure 1 and Figure 3After the two wires B are respectively passed through the two threading holes 24 of the deflection seat 20, and electric power is transmitted to the magnetic coil 30, the magnetic coil 30 can generate a magnetic field and mutually induce with the magnetic part 28 set on the deflection member 20, so that the deflection member 20 can be made to rotate relative to the deflection seat 10 with the deflection axis 222 as the axis. When the size and direction of the electric power input into the magnetic coil 30 are changed, the size and direction of the magnetic field generated by the magnetic coil 30 can be changed. In this way, the magnetic part 28 set on the deflection member 20 can be mutually induced by the change in the size and direction of the magnetic field generated by the magnetic coil 30, so that the deflection direction of the deflection member 20 relative to the deflection seat 10 can be changed, and the hook A corresponding to one of the threading holes 24 can be changed, thereby achieving the effect of changing the input direction of the wire B.

[0051] The wire deflector of the present invention can not only effectively reduce the weight of the wire deflector as a whole, but also appropriately reduce the volume of the wire deflector as a whole, thereby reducing the space required for the wire deflector to be installed on the machine, thereby achieving a miniaturized and lightweight design effect. At the same time, the present invention uses the size and direction of the magnetic field generated by the magnetic coil 30 to change by changing the size and direction of the current to control the swing direction of the deflector 20, so there will be no delay in changing the direction of the existing motor, which can make the input of the wire B smoother, thereby improving the overall manufacturing and processing efficiency.

[0052] It can be seen from the above content that different modifications and changes can be achieved without departing from the essential spirit and novel concept of the present invention, and the specific embodiments disclosed in the present invention are not used to limit the present invention. This disclosure includes all modifications that fall within the scope of the attached patent application.
