Description

Technical Field

[0001] The utility model relates to the technical field of cutting line sharpening equipment, in particular to a bidirectional sharpening and rewinding machine. Background Art

[0002] Sharpening and rewinding machines are mostly used for sharpening diamond wires. The diamond wires are ground using a sharpening wheel to obtain sharp cutting wires.

[0003] The common sharpening and rewinding machines on the market usually unwind the material on one side, sharpen it, and then rewind it on the other side. Since the sharpening wheel may wear out during long-term use, the sharpening degree that can be achieved in one sharpening may not meet the expected requirements, affecting the quality of the finished product. Utility Model Content

[0004] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides a bidirectional sharpening and rewinding machine with a reasonable structure, which can rewind and sharpen in both directions. If the sharpening cannot meet the expected requirements at one time, the sharpening can be performed again in the reverse direction on the same device.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A two-way bladed rewinding machine comprises a rewinding and unwinding mechanism and a bladed mechanism. The rewinding and unwinding mechanisms are symmetrically arranged on both sides of the bladed mechanism and have a two-way rewinding and unwinding function.

[0007] The reeling and unreeling mechanism includes an I-shaped wheel for winding the diamond wire, a power source for driving the I-shaped wheel to rotate, and a tightening member for limiting the I-shaped wheel.

[0008] A sliding guide wheel group is arranged on the output direction of the diamond wire on the I-shaped wheel, and a traction wheel and a tension adjustment wheel are arranged on the output direction of the sliding guide wheel group; the diamond wire enters the sharpening mechanism after passing through the sliding guide wheel group, the traction wheel and the tension adjustment wheel, and the diamond wire output from the sharpening mechanism enters the reeling and winding mechanism on the other side.

[0009] As a further improvement of the above technical solution:

[0010] The reeling and unreeling mechanisms on both sides each have an independent power source.

[0011] The power source of the rewinding and unwinding mechanism is a motor, and the motor is connected to the wheel shaft of the I-shaped wheel by a belt transmission.

[0012] The belt transmission structure between the motor and the wheel shaft of the I-shaped wheel includes a balance wheel for resisting the transmission belt.

[0013] A tightening cylinder is arranged on the side of the I-shaped wheel facing away from the motor.

[0014] The sliding guide wheel group comprises two unpowered guide wheels, the relative position between the two unpowered guide wheels is constant, and the two unpowered guide wheels slide back and forth at the same time.

[0015] A steering guide wheel group is provided in the output direction of the sliding guide wheel group, and the steering guide wheel group and the sliding guide wheel group slide back and forth synchronously.

[0016] The power source of the tension adjustment wheel adopts a servo motor, the output shaft of the servo motor is connected with a swing rod, and the tension adjustment wheel is rotatably connected to the other end of the swing rod.

[0017] At least one of the traction wheels has a tension monitoring function.

[0018] The sharpening mechanism comprises a plurality of sharpening wheels, and a dust collecting groove is arranged below the sharpening wheels; the traction wheels and the tension adjusting wheels on both sides of the sharpening mechanism are symmetrically arranged.

[0019] The beneficial effects of the utility model are as follows:

[0020] The main advantage of the utility model is that the reeling and unreeling mechanism can rotate forward and reverse, and each reeling and unreeling mechanism can be used for unwinding and rewinding. If the sharpening does not meet the expected requirements, the original reeling part can be used as the unwinding part and the original unwinding part as the rewinding part on the same device, and the reverse output sharpening can be performed again until the sharpening degree of the diamond wire meets the expected requirements.

[0021] In the utility model, the I-shaped wheels of the reeling and winding mechanism are each equipped with a sliding guide wheel group, and the two unpowered guide wheels of the sliding guide wheel group are driven by the diamond wire. When the diamond wire is pressed on one of the unpowered guide wheels, the guide wheel rotates, and the other guide wheel does not move. The two unpowered guide wheels slide with the swing of the diamond wire wound on the I-shaped wheels, playing a guiding and traction role.

[0022] Each side of the reeling and unreeling mechanism of the utility model is also provided with a tension regulating wheel for monitoring and regulating the tensioning force on the diamond wire. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] like Figure 1-Figure 3 As shown, the blade opening rewinding machine includes a frame, a blade opening mechanism 2 is in the middle of the frame, and winding and unwinding mechanisms 1 are symmetrically arranged on both sides of the blade opening mechanism 2. In this embodiment, in order to allow the winding and unwinding mechanisms 1 on both sides to have winding and unwinding functions, two sets of winding and unwinding mechanisms 1 with the same structure are used for installation.
