Description

Technical Field

[0001] The utility model belongs to the technical field of wire take-up machines, and in particular relates to a reel-changing and wire-clamping mechanism applied to a wire take-up machine. Background Art

[0002] After the wire is formed, it needs to be wound and collected for subsequent processing. The equipment for winding and collecting is the wire take-up machine.

[0003] At present, when the wire take-up machine cuts the wire and changes the reel, there is a fixed mechanism for clamping the wire. For example, the utility model patent with the announcement number "CN205527045U" and the name "Automatic reel changing device using a fixed reel take-up method" discloses an automatic reel changing device using a fixed reel take-up method, which includes a wire guide wheel and two sets of wire take-up mechanisms. The wire is wound around the wire guide wheel and then wound on one set of wire take-up mechanisms. The other set of wire take-up mechanisms is provided with a wire catcher. A wire pulling mechanism is provided between the wire guide wheel and the wire take-up mechanism. When working, one set of wire take-up mechanisms works to take up the wire. When the wire take-up mechanism has finished taking up the wire, the wire pulling mechanism starts to pull the wire to a position where the wire catcher of the other set of wire take-up mechanisms can catch it. The wire catcher automatically catches the wire and cuts it, allowing the wire to be smoothly wound onto the other set of wire take-up mechanisms, thus realizing the automatic reel changing action from one set of wire take-up mechanisms to another. That is, when the wire is cut and the reel is changed, the wire is cut by the pulling action of the wire catcher. Since there is no mechanism to clamp and fix the wire, the wire will continue to be pulled out due to the pulling action of the wire catcher, which may easily lead to wire cutting failure and affect the wire taking-up efficiency. Utility Model Content

[0004] In view of the above-mentioned shortcomings, the purpose of the present invention is to provide a reel-changing wire clamping mechanism with a reasonable structural design and capable of clamping and positioning wires.

[0005] To achieve the above-mentioned purpose, the technical solution provided by the utility model is: a disc-changing wire clamping mechanism, which includes an incoming wire guide wheel, an outgoing wire guide wheel, a wire-passing hollow shaft, a mounting seat, a fixed clamping block, a movable clamping block and a pushing device, the incoming wire guide wheel and the outgoing wire guide wheel are arranged at the two end positions of the wire-passing hollow shaft, the wire-passing hollow shaft is provided with a radial through hole that radially passes through it, the mounting seat is arranged on the wire-passing hollow shaft at a position corresponding to the radial through hole, the fixed clamping block is arranged on the mounting seat and is located at one end position of the radial through hole, the movable clamping block is movably located at one end position of the radial through hole, the pushing device is arranged on the mounting seat, and can drive the movable clamping block to move closer or apart relative to the fixed clamping block.

[0006] As a preferred solution of the present invention, the mounting seat includes a clamp and a clamp seat, and the clamp and the clamp seat are both provided with an arc-shaped recess adapted to the wire-passing hollow shaft. The clamp and the clamp seat are connected by bolts, so that the mounting seat can be firmly fixed on the wire-passing hollow shaft, and is easy to disassemble and maintain.

[0007] In a preferred embodiment of the present invention, the driving device is a pneumatic cylinder mounted on the clamping base, with an opening in the clamping base for the cylinder's piston rod to extend into a radial through-hole. The pneumatic cylinder as a driving device offers advantages such as fast response, simple control, and high driving force. By driving the movable clamping block toward or away from the fixed clamping block, the pneumatic cylinder can rapidly clamp and release the wire.

[0008] As a preferred solution of the present invention, a wire-entering guide wheel housing is fixedly provided at one end of the wire-passing hollow shaft, a wire-entering rotating shaft is provided in the wire-entering guide wheel housing, and the wire-entering guide wheel is arranged on the wire-entering rotating shaft through a wire-entering bearing, so that the wire-entering guide wheel can rotate smoothly, reducing the friction and resistance of the wire during the introduction process and improving the transmission efficiency of the wire.

[0009] As a preferred embodiment of the present invention, the other end of the hollow wire-passing shaft is rotatably mounted on a wire-out guide wheel housing via a grooved ball bearing. A meter-counting wheel shaft is located at the center of the wire-out guide wheel, and the meter-counting wheel shaft is mounted on the wire-out guide wheel housing via a wire-out bearing. This not only ensures smooth rotation of the wire-out guide wheel, but also allows the wire-out guide wheel to rotate toward a desired position around the hollow wire-passing shaft.

[0010] As a preferred solution of the present invention, the meter wheel shaft is connected to a rotary encoder to achieve measurement of the wire length.

[0011] As a preferred solution of the present invention, the fixed clamping block and the movable clamping block are both made of soft rubber blocks, which can increase the clamping force of the clamping block on the wire and avoid damage to the wire.

[0012] As a preferred solution of the present invention, a bearing seat is provided on the wire-passing hollow shaft through a bearing, which makes installation convenient.

[0013] The beneficial effects of the present invention are as follows: the present invention has a reasonable structural design. When the wire cutting reel needs to be changed, the pushing device drives the movable clamping block to approach the fixed clamping block to clamp and position the wire, thus achieving the clamping and positioning function of the wire during the wire cutting reel change, effectively preventing the wire from being pulled out due to the pulling force of the cutting during the wire cutting reel change, ensuring the wire cutting effect and improving the wire taking-up efficiency. In addition, the overall structure is simple, the cost is low, and it is easy to implement.

[0020] See also Figures 1 to 5 The present embodiment provides a disc-changing and line-clamping mechanism, which includes an inlet guide wheel 1, an outlet guide wheel 2, a line-passing hollow shaft 3, a mounting seat 4, a fixed clamping block 5, a movable clamping block 6 and a pushing device 7.

[0021] The inlet guide wheel 1 and the outlet guide wheel 2 are arranged at the two ends of the wire-passing hollow shaft 3. Preferably, an inlet guide wheel housing 8 is fixedly provided at the lower end of the wire-passing hollow shaft 3. An inlet rotating shaft 81 is provided in the inlet guide wheel housing 8. The inlet guide wheel 1 is arranged on the inlet rotating shaft 81 through an inlet bearing 82, so that the inlet guide wheel 1 can rotate smoothly, reducing the friction and resistance of the wire during the introduction process and improving the transmission efficiency of the wire. The upper end of the wire-passing hollow shaft 3 is rotatably provided with an outlet guide wheel housing 9 through a groove ball bearing 91. The center position of the outlet guide wheel 2 is provided with a meter wheel shaft 92. The meter wheel shaft 92 is arranged on the outlet guide wheel housing 9 through an outlet bearing 93. Not only does it ensure the smooth rotation of the outlet guide wheel 2, but it also allows the outlet guide wheel 2 to rotate toward the desired position with the wire-passing hollow shaft 3 as the axis. Preferably, a rotary encoder 94 is connected to the meter wheel shaft 92 to achieve measurement of the wire length.

[0022] A radial through hole is provided on the wire-passing hollow shaft 3, which radially passes through it. The mounting seat 4 is set on the wire-passing hollow shaft 3 at a position corresponding to the radial through hole. Specifically, the mounting seat 4 includes a clamp 41 and a clamp seat 42. The clamp 41 and the clamp seat 42 are both provided with an arc-shaped recess that is compatible with the wire-passing hollow shaft 3. The clamp 41 and the clamp seat 42 are connected by bolts, so that the mounting seat 4 can be firmly fixed on the wire-passing hollow shaft 3, and is convenient for disassembly and maintenance.

[0023] The fixed clamping block 5 is disposed on the mounting base 4 and is located at one end of the radial through hole. The movable clamping block 6 is movably located at one end of the radial through hole. Both the fixed clamping block 5 and the movable clamping block 6 are preferably made of soft rubber blocks, such as silicone blocks. This can increase the clamping force of the clamping blocks on the wire while preventing damage to the wire.

[0024] The pushing device 7 is arranged on the mounting base 4, and can drive the movable clamping block 6 to move closer to or apart from the fixed clamping block 5. In this embodiment, the pushing device 7 is preferably a cylinder, and the cylinder is mounted on the clamping base 42, and an opening is provided on the clamping base 42 for allowing the piston rod of the cylinder to extend into the radial through hole. The cylinder as the pushing device 7 has the advantages of fast response speed, simple control, and large driving force. By driving the movable clamping block 6 to move closer to or apart from the fixed clamping block 5 by the cylinder, the wire can be quickly clamped and released. In other embodiments, the pushing device 7 can also be an oil cylinder, a linear motor or other linear drive device.

[0025] In order to facilitate installation on the frame of the wire taking-up machine, a bearing seat 10 is provided on the wire passing hollow shaft 3 through a bearing, and the reel changing and wire clamping mechanism of the present invention can be installed on the frame of the wire taking-up machine through the bearing seat 10.

[0026] During operation, when the wire take-up machine is normally winding the wire, the pushing device 7 drives the movable clamping block 6 to move backward away from the fixed clamping block 5 to achieve the purpose of loosening the wire. When the wire needs to be cut and the reel needs to be changed, the pushing device 7 drives the movable clamping block 6 to move forward close to the fixed clamping block 5 to clamp and position the wire, realizing the clamping and positioning function of the wire during the cut and reel change, effectively preventing the wire from being pulled out due to the tangent pulling force during the cut and reel change, and ensuring the cut effect.
