Abstract
Description
Technical Field
[0001] The invention relates to a spindle with stepless tension adjustment for a braiding machine, belonging to the technical field of braiding machines. Background Art
[0002] During the weaving process, the spindle of the braiding machine needs to provide a certain amount of tension to the wire on it, so that the braided material is uniform and the product quality is guaranteed. Most existing braiding machine spindles provide tension to the wire through elastic structures and wire wheels. This practice increases the complexity of the spindle structure and makes it difficult to perform stepless linear adjustment of the tension. Usually, a fixed value is set according to the different braiding materials, which is difficult to meet the complex and sophisticated braiding needs. Summary of the invention
[0003] The technical problem to be solved by the present invention is: to overcome the disadvantages of the above-mentioned technology and provide a braiding machine spindle capable of steplessly adjusting the tension.
[0004] In order to solve the above technical problems, the technical solution proposed by the present invention is: a spindle for stepless tension adjustment of a braiding machine, comprising: a base, a top cover and a bracket connecting the base and the top cover; a bobbin shaft is installed between the base and the top cover; a bobbin is sleeved on the bobbin shaft; the top end of the bobbin shaft is hinged to the top cover, and the bottom end of the bobbin shaft extends into the base, and the base is provided with a mounting block fixedly connected to the bobbin shaft; the top of the mounting block is provided with a first friction plate; a second friction plate is tightly attached to the first friction plate; an adjusting nut is provided above the second friction plate; the adjusting nut is threadedly connected to the base; the first friction plate rotates synchronously with the mounting block; the second friction plate rotates synchronously with the adjusting nut; the bottom of the mounting block is provided with a first magnet; the bottom of the base is provided with a second magnet; the first magnet and the second magnet are opposite to each other with the same poles; as the adjusting nut is screwed in or out of the base, the distance between the first magnet and the second magnet becomes smaller or larger.
[0005] A further improvement of the above solution is that the first magnet and the second magnet are annular magnets or a magnet group arranged in an annular shape.
[0006] A further improvement of the above scheme is that: the first friction plate is restricted by the mounting block through the slot and the block in rotation relative to the mounting block; the second friction plate is restricted by the adjusting nut through the slot and the block in rotation relative to the adjusting nut.
[0007] A further improvement of the above scheme is that: the top cover is provided with a bearing for receiving the bobbin shaft.
[0008] A further improvement of the above solution is that the bobbin shaft can move relative to the bearing along the axial direction of the bobbin shaft.
[0009] The above scheme is further improved in that: a receiving seat for receiving the bobbin shaft is provided above the base; a gap is provided between the receiving seat and the adjusting nut; and the receiving seat is threadedly connected to the mounting block.
[0010] A further improvement of the above solution is that the base is made of non-magnetic material.
[0011] A further improvement of the above solution is that the base is made of aluminum alloy.
[0012] The spindle for stepless tension adjustment of the braiding machine provided by the present invention can adjust the pressure between the friction plates by adjusting the settings of the nut and the magnet, thereby changing the friction between the friction plates, and the pulling force needs to overcome the friction force, thereby realizing stepless adjustment of the pulling force. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] The present invention will be further described below in conjunction with the accompanying drawings.
[0014] Figure 1 It is a schematic structural diagram of a preferred embodiment of the present invention.
[0015] Figure 2 yes Figure 1 Section view. DETAILED DESCRIPTION Example
[0016] The spindle of the braiding machine of this embodiment with stepless tension adjustment is as follows: Figure 1 and Figure 2 As shown, it comprises: a base 2, a top cover 1 and a bracket 3 connecting the base 2 and the top cover 1; a bobbin shaft 4 is installed between the base 2 and the top cover 1; a bobbin 5 is sleeved on the bobbin shaft 4; the top end of the bobbin shaft 4 is hinged with the top cover 1, and the bottom end of the bobbin shaft 4 extends into the base 2, and the base 2 is provided with a mounting block 6 fixedly connected with the bobbin shaft 4; the top of the mounting block 6 is provided with a first friction plate 7; a second friction plate 8 is closely attached to the first friction plate 7; an adjusting nut 9 is provided above the second friction plate 8; the adjusting nut 9 is threadedly connected with the base 2; the first friction plate 7 is restricted by the mounting block 6 to rotate relative to the mounting block 6 through the slot and the block, thereby realizing the synchronous rotation of the first friction plate 7 and the mounting block 6; the second friction plate 8 is restricted by the adjusting nut 8 to rotate relative to the adjusting nut 8 through the slot and the block, thereby realizing the synchronous rotation of the second friction plate 8 and the adjusting nut 9; the bottom of the mounting block 6 is provided with a first magnet 11; the bottom of the base 2 is provided with a second magnet 12; the first magnet 11 and the second magnet 12 are opposite to each other with the same poles.
[0017] The top cover 1 has a bearing for receiving the bobbin shaft 4. The bobbin shaft 4 can move along the axial direction of the bobbin shaft 4 relative to the bearing.
[0018] A receiving seat 13 for receiving the bobbin shaft 4 is provided above the base 2; there is a gap between the receiving seat 13 and the adjusting nut 9; the receiving seat is threadedly connected to the mounting block 6. In this way, the bobbin 5 and the bobbin shaft 4 are connected as one body and rotate coaxially.
[0019] As the adjusting nut 9 is screwed in or out of the base 2, the distance between the first magnet 11 and the second magnet 12 becomes smaller or larger. In this way, the repulsive force generated by the first magnet 11 and the second magnet 12 will increase or decrease, and then be transmitted to the first friction plate 7 and the second friction plate 8; the pressure between the first friction plate 7 and the second friction plate 8 will increase or decrease accordingly, and further, the friction between the two will be changed. The rotation of the bobbin 5 must overcome this friction force, and the rotation of the bobbin 5 is pulled by the wire wound on it, that is, the friction force is the tension of the wire. Therefore, by rotating the adjusting nut 9, stepless and linear tension adjustment can be achieved. By replacing different friction plates, the adjustment range can also be changed.
[0020] In order to ensure the stability of the repulsive force, the first magnet 11 and the second magnet 12 are annular magnets or magnet groups arranged in an annular shape.
[0021] Similarly, in order to further ensure the stability of the magnetic field and prevent the base 2 from interfering with the distribution of magnetic lines of force, the base 2 is made of a non-magnetic material, such as aluminum alloy or wood.
[0022] The present invention is not limited to the above embodiments. Any technical solution formed by equivalent replacement falls within the protection scope required by the present invention.
