[0023] According to an embodiment of this utility model, a wire conveying mechanism is provided. Please refer to [link / reference]. Figures 1 to 2 The assembly includes: a mounting plate 1 extending vertically and mounted on a mounting reference; a wire clamping assembly 2 having a first wire clamping portion and a second wire clamping portion; the first wire clamping portion being disposed on the mounting plate 1, and the first and second wire clamping portions being spaced apart along the extending direction of the mounting plate 1, the second wire clamping portion being movably disposed on the mounting plate 1 along the extending direction of the mounting plate 1; both the first and second wire clamping portions being used to clamp wires; and the wire is bent... The bending assembly 3 is mounted on the mounting plate 1 and is spaced apart from the wire clamping assembly 2 along the extension direction of the mounting plate 1. The wire bending assembly 3 is used to bend the wire clamped by the wire clamping assembly 2. The motor drive assembly 4 is mounted on the mounting plate 1 and is located on one side of the wire clamping assembly 2. The motor drive assembly 4 is used to drive the second wire clamping part to move so that the second wire clamping part moves the clamped wire onto the wire bending assembly 3.

[0024] By adopting the above technical solution, the motor drive assembly 4 is used to drive the second wire clamping part to move, thereby moving the wire. The speed of wire feeding can be controlled by adjusting the rotation speed, avoiding intermittent stops in the cylinder feeding of wire, increasing the wire feeding time, and thus improving the efficiency of brush making.

[0025] Please refer to Figure 1 The motor drive assembly 4 includes a motor drive unit and a transmission unit. The motor drive unit is mounted on the mounting plate 1. The transmission unit is connected to the motor drive unit and the second wire clamping unit respectively. The motor drive unit drives the second wire clamping unit to move through the transmission unit, so that the wire clamped by the second wire clamping unit moves to the wire bending assembly 3.

[0026] By adopting the above technical solution, the motor drive unit and the transmission unit work together to drive the steel wire to move, providing the power for conveying the steel wire.

[0027] Please refer to Figure 1 and Figure 2 The motor drive assembly 4 also includes: a servo motor 5, which is mounted on the side of the mounting plate 1 away from the wire bending assembly 3; a drive gear 6, the output end of the servo motor 5 passing through the mounting plate 1 and protruding from the mounting plate 1, the drive gear 6 being drivenly connected to the output end of the servo motor 5, and the drive gear 6 being rotatably mounted on the mounting plate; a driven gear 7, which is spaced apart from the drive gear 6 along the extension direction of the mounting plate 1, and the driven gear 7 being rotatably mounted on the mounting plate 1; and a toothed belt 8, consisting of 8 sets of toothed belts. A toothed belt 8 is connected to the driving gear 6 and the driven gear 7 respectively, so that the driving gear 6 drives the toothed belt 8 to move, thereby driving the driven gear 7 to rotate; a toothed plate 9 is mounted on the toothed belt 8 and is located on the outer wall of the toothed belt 8. The toothed plate 9 is connected to the second wire clamping part, and the toothed belt 8 drives the second wire clamping part to move through the toothed plate 9; wherein, the servo motor 5 forms a motor drive part; the driving gear 6, the driven gear 7, the toothed belt 8, and the toothed plate 9 form a transmission part.

[0028] By adopting the above technical solution, and using a transmission system consisting of a servo motor 5, a drive gear 6, a driven gear 7, and a toothed belt 8, continuous and stable movement of the second wire clamping part can be achieved. The rigid connection between the toothed plate 9 and the toothed belt 8 ensures the synchronization of power transmission, and the precise speed control of the servo motor 5 makes the wire conveying stroke adjustable, avoiding the intermittent pauses caused by cylinder drive, significantly improving the continuity and positioning accuracy of wire conveying, and reducing the impact of impact vibration on equipment lifespan.

[0029] Please refer to Figure 1The motor drive assembly 4 also includes: a slide rail 10, which extends along the extension direction of the mounting plate 1, and the slide rail 10 and the drive gear 6 are spaced apart along the width direction of the mounting plate 1. The slide rail 10 is mounted on the mounting plate 1, and the second wire clamping part is movably mounted on the slide rail 10 along the extension direction of the slide rail 10.

[0030] By adopting the above technical solution, the slide rail 10 is set along the extension direction of the mounting plate 1 and forms a parallel layout with the drive gear 6, providing double guiding constraints for the second wire clamping part; the linear guiding characteristics of the slide rail 10 can effectively eliminate the radial offset error in the transmission process of the toothed belt 8, while sharing the lateral load of the clamping cylinder, enhancing the motion stability of the mechanism, extending the service life of the transmission components, and ensuring the straightness of the wire conveying path.

[0031] Please refer to Figure 1 The wire clamping assembly 2 includes: a first clamping cylinder 11, which is mounted on the mounting plate 1 and is used to clamp a wire; and a second clamping cylinder 12, which is movably disposed on the mounting plate 1 along the extending direction of the mounting plate 1, and is spaced apart from the first clamping cylinder 11 along the extending direction of the mounting plate 1; the second clamping cylinder 12 is connected to a transmission unit to drive the second clamping cylinder 12 to move, so that the wire clamped by the second clamping cylinder 12 is moved to the wire bending assembly 3. The first clamping cylinder 11 forms a first wire clamping part; and the second clamping cylinder 12 forms a second wire clamping part.

[0032] By adopting the above technical solution, the first clamping cylinder 11 and the second clamping cylinder 12 form an alternating clamping mechanism; when the second clamping cylinder 12 moves through the transmission unit, the first clamping cylinder 11 cancels the clamping state; when the second clamping cylinder 12 releases the steel wire, the first clamping cylinder 11 maintains the clamping state, forming a segmented relay conveying mode, realizing continuous and gradual conveying of the steel wire, avoiding the conveying interruption caused by traditional single-point clamping, and at the same time, the alternating work of the two clamping points can compensate for the transmission gap.

[0033] Please refer to Figure 2 The wire conveying mechanism further includes: a connecting plate 13, which extends along the thickness direction of the mounting plate 1 and is mounted on the side of the mounting plate 1 away from the first clamping cylinder 11; and a wire feeding roller 14, whose extension direction is perpendicular to the extension direction of the connecting plate 13, which is rotatably mounted on the connecting plate 13, and on which a wire is wound.

[0034] By adopting the above technical solution, the connecting plate 13 and the mounting plate 1 form an L-shaped support structure. The wire feeding roller is horizontally mounted on the connecting plate. This setting method effectively utilizes three-dimensional space, optimizes the space utilization of the equipment, reduces the torsional stress during the wire conveying process, and facilitates the operator to replace the wire.

[0035] Please refer to Figure 1 The wire conveying mechanism further includes: a wire tensioning assembly 15, which includes: an extension plate 16 extending along the extension direction of the mounting plate 1, the extension plate 16 being mounted on the top of the mounting plate 1 and protruding from the mounting plate 1; a groove being provided on the side of the extension plate 16 near the first clamping cylinder 11, the groove extending along the extension direction of the extension plate 16; and a driving member 17 extending and retracting in the vertical direction, the driving member 17 being mounted on the side of the extension plate 16 near the first clamping cylinder 11. 1. One side; slide 18, slide 18 is movably disposed in the slide groove along the extension direction of the slide groove, slide 18 is driven to be connected to the telescopic end of the drive member 17 so that the slide 18 is moved along the extension direction of the slide groove by the telescopic extension of the drive member 17; guide wheel 19, guide wheel 19 is rotatably disposed on the side of slide 18 away from the slide groove; wherein, the wire is output by the wire feeding roller 14 and passes through the guide wheel 19, the first clamping cylinder 11, the second clamping cylinder 12 and the wire bending assembly 3 in sequence.

[0036] By adopting the above technical solution, the drive component 17 drives the guide wheel 19 to move along the slide groove through the slide block 18, forming a dynamic tension adjustment mechanism; the extension direction of the slide groove is parallel to the wire conveying path, and the position change of the guide wheel 19 can change the wrap angle of the wire in real time, automatically compensate for the relaxation phenomenon caused by the stretching deformation of the wire, ensure the constant tension during the conveying process, and adapt to the process requirements of wires of different diameters.

[0037] Please refer to Figure 1 The wire bending assembly 3 includes: a limiting plate 20, which extends along the width direction of the mounting plate 1, and has a limiting channel and a clearance opening communicating with the limiting channel. The limiting channel extends along the height direction of the limiting plate 20 and is used to limit the wire. The clearance opening is located on the side of the limiting plate 20 near the second wire clamping part. A bending blade 21 extends along the thickness direction of the mounting plate 1, and the bending end of the bending blade 21 is located at the bottom of the limiting channel. The bending blade 21 is movably arranged along the width direction of the mounting plate 1 to bend the limited wire.

[0038] By adopting the above technical solution, the limiting channel of the limiting plate 20 and the avoidance port form a guiding positioning structure, and the bending knife 21 adopts a lateral movement bending method; the vertical constraint of the limiting channel and the lateral opening of the avoidance port cooperate to ensure that the steel wire retains only the axial degree of freedom when bending, which improves the repeatability accuracy of the bending angle, avoids bending deformation caused by the lateral sliding of the steel wire, and facilitates the maintenance and replacement of the bending knife.

[0039] A brush-making machine includes the aforementioned wire conveying mechanism.

[0040] By applying the aforementioned wire feeding mechanism to the brush-making machine, the coordinated operation of each functional module forms a complete wire processing system. The cooperation between the servo drive system and the clamping components enables high-precision intermittent feeding, while the linkage between the tensioning and bending components ensures process stability, significantly improving the automation level of brush production and ensuring the consistency of wire structure formation and yield rate in brush products.

[0041] Working principle:

[0042] Step 1: Steel wire pre-installation and tension adjustment;

[0043] The coiled steel wire is placed on the pay-off roller 14, and the end of the steel wire is led out by the pay-off roller 14. The steel wire passes through the guide wheel 19, the gap between the jaws of the first clamping cylinder 11, and the gap between the jaws of the second clamping cylinder 12 in sequence, and finally extends into the limiting channel of the steel wire bending assembly 3. The driving component 17 (such as a cylinder or electric push rod) pushes the slide block 18 to move along the slide groove, which drives the guide wheel 19 to change the wrap angle of the steel wire, so that the steel wire is in a moderately tensioned state.

[0044] Step 2: Clamping and initial positioning;

[0045] The first clamping cylinder 11 clamps the steel wire and fixes the position of the front end of the steel wire.

[0046] The second clamping cylinder 12 clamps the steel wire, at which point the steel wire is simultaneously fixed by the first clamping cylinder 11 and the second clamping cylinder 12.

[0047] Step 3: Intermittent feeding;

[0048] The first clamping cylinder 11 releases the gripper, while only the second clamping cylinder 12 remains in the clamping state. The servo motor 5 drives the second clamping cylinder 12 to move along the slide rail 10 toward the wire bending assembly 3 via the toothed belt 8 and toothed plate 9, pushing the wire forward by a set stroke. When the second clamping cylinder 12 reaches the target position, the first clamping cylinder 11 re-clamps the wire.

[0049] Step 4: Bending and shaping;

[0050] The second clamping cylinder 12 releases the steel wire, and the servo motor 5 reverses to drive it back to the initial position along the slide rail 10; the curved blade 21 moves laterally and presses the end of the steel wire that has passed through the limiting channel into the clearance opening to complete the U-shaped or L-shaped bending action; the vertical channel of the limiting plate 20 restricts the lateral displacement of the steel wire to ensure the consistency of the bending angle.

[0051] Step 5: Repeat the process;

[0052] Repeat steps 2 to 4 to achieve continuous segmented conveying of the steel wire through the alternating clamping and releasing action of the first clamping cylinder 11 and the second clamping cylinder 12; the drive component 17 adjusts the position of the guide wheel 19 in real time according to the tension of the steel wire to maintain constant conveying tension.
