Description

Technical Field

[0001] The present application relates to the field of multi-wire cutting machines, and in particular to a segmented tension adjustment mechanism. Background Art

[0002] The wire saw is mainly composed of a support and a cutting component, and the cutting component can move up and down relative to the support. Figure 1 The cutting assembly includes a mounting frame, a plurality of main guide wheels 2 rotatably arranged on the mounting frame, and two sets of retractable wire systems 3. The cutting wire 4 is led out from the first set of retractable wire system and is reciprocated on each main guide wheel to form a cutting mesh 41. The end of the cutting wire is connected to the second set of retractable wire system 3. When the main guide wheel rotates forward and backward, it can drive the cutting mesh to reciprocate and saw the material to cut. During the cutting process, the first set of retractable wire system will continuously release new cutting wires, and the second set of retractable wire system will continuously retract the old wires that are worn out.

[0003] In the wire saw of the related art, the cutting wire needs to be continuously wound from the head to the tail of the main wheel, that is, a cutting wire is wound around each main wheel for many turns, and the length of the cutting wire pulled out is very long, which will greatly increase the probability of the cutting wire breaking, and after the wire breaks, it needs to be rethreaded from the beginning to the end, which is troublesome to repair. In order to solve the above problems, the inventor of the present application has designed a method of using multiple cutting wires and winding them in sections, which can greatly reduce the risk of cutting wire breaking.

[0004] Since the reel-and-release system usually has a tension adjustment mechanism for adjusting the tension of the reel-and-release wires, as the number of cutting wires increases, it is necessary to ensure that the tension of each cutting wire remains consistent. The tension adjustment mechanism in the related art is a motor driving a tension wheel to swing. If a tension adjustment mechanism is configured for each cutting wire, the cost is high and it takes up a lot of space. Summary of the invention

[0005] In view of this, the present application provides a segmented tension adjustment mechanism, which is suitable for adjusting the tension of more than two cutting lines. It can not only keep the same tension on each cutting line, but also has low cost, convenient adjustment and small space occupation.

[0006] In order to achieve the above objectives, this application is implemented through the following technical solutions:

[0007] A segmented tension adjustment mechanism, characterized in that: it includes more than two tension wheels for respectively adjusting the tightness of different cutting lines, and a tension driving assembly for controlling and adjusting the movement of each tension wheel to keep the tension of each cutting line consistent; the tension driving assembly includes a flexible rope with both ends fixed on a mounting frame, and a toggle adjustment assembly for adjusting the tension of the flexible rope to a preset value; each tension wheel is provided with a rocker arm and a linkage wheel for controlling the swing of the rocker arm, the linkage wheel and the tension wheel of the same group are both mounted on the free end of the rocker arm, the rocker arm is connected to the mounting frame in a rotatable manner, so that the linkage wheel and the tension wheel can swing synchronously around the rotation axis of the rocker arm and the mounting frame, each linkage wheel is connected to the flexible rope, and can keep the tension of the cutting lines respectively tensioned by each tension wheel consistent under the pulling of the flexible rope.

[0008] The above-mentioned segmented tension adjustment mechanism of the present application can adjust the tension of each cutting line to be consistent, and has low cost, small space occupation, and is easy to use. The tension adjustment structure in this embodiment is a flexible structure, which is suitable for cutting marble and other stone materials, wherein the tension of each cutting line is greatly adjusted during the cutting process, and the swing direction and angle of each linkage wheel are different. When the tension of the flexible rope of each linkage wheel is about to change during the deflection process, the adjustment component intervenes to keep the tension of the tension rope at a constant value, so that the tension rope can pull each linkage wheel so that the tension of the cutting line pressed against each tension wheel remains consistent.

[0009] In some embodiments, the flexible rope is wound around the bottom of each linkage wheel in turn, and the mounting frame is further provided with at least one winding wheel above each two adjacent linkage wheels for pulling upward the flexible rope between the two adjacent linkage wheels, and the flexible rope between the two adjacent linkage wheels is wound around the upper part of the corresponding winding wheel.

[0010] In some embodiments, the toggle adjustment component includes a second tension motor and a rotating arm connected to the output shaft of the second tension motor, the second tension motor is used to drive the rotating arm to swing, a toggle wheel for adjusting the tightness of the flexible rope is installed on the free end of the rotating arm, and the flexible rope between a fixed end of the flexible rope and the linkage wheel closest to the fixed end is wound around the toggle wheel, so that the tightness of the flexible rope is adjusted by the swing of the toggle wheel relative to the swing center of the rotating arm. This embodiment is driven by only one motor, which can greatly reduce production costs and make regulation more convenient.

[0011] In some embodiments, the rocker arm is rotatably connected to the mounting frame via a rotating shaft, the rocker arm is V-shaped, and the linkage wheel and the tension wheel are respectively mounted on two free end feet of the V-shape of the rocker arm.

[0012] It can be seen from the above technical solution that the present application has at least the following advantages and positive effects:
