Description

Technical Field

[0001] The invention belongs to the technical field of copper wire feeding, in particular to feeding equipment for a copper wire cutting machine. Background Art

[0002] Loading refers to the process of sending the workpiece to the working position and achieving positioning and clamping. In copper wire processing, the copper wire is moved to achieve the processing effect of different steps. When processing the copper wire, the use of loading equipment can quickly move its position to facilitate subsequent processing. When the loading equipment is used, the copper wire drum on the equipment rotates, and then the copper wire is pulled by the drum to achieve the feeding effect.

[0003] A patent with publication number CN115213254A discloses an automatic feeding device for copper wire processing, comprising: a body, including a support frame, the surface of the support frame is fixedly connected to a support plate, the surface of the support frame is fixedly connected to a support rod, the outer surface of the support rod is sleeved with a wire bobbin; a feeding mechanism, including a connecting plate, the connecting plate is fixedly connected to the surface of the support plate, the surface of the connecting plate is fixedly connected to an adjustment bin, the outer surface of the adjustment bin is fixedly connected to a motor. The present invention realizes the rotation of the rotating ring on the second clamping barrel under the rotation connection of the rotating teeth and the movable teeth, and achieves the rotation in opposite directions between the rotating ring and the first clamping barrel through the action of the movable teeth, realizes the clamping rotation of the copper wire, and then achieves the feeding effect of the copper wire, and under the connection of the action ring and the rotating handle, realizes the support of the wire bobbin at the action position on the support rod, and achieves the effect of installing and replacing the wire bobbin on the support frame.

[0004] In the current existing technology, the hardness of copper wire is medium among metals, and its Mohs hardness is approximately between 2.5 and 3, which makes the copper wire relatively soft. When the existing copper wire is loaded, both the thin copper wire and the thick copper wire need to be pulled out from the storage tube. The thick copper wire is thicker, which leads to a heavier overall weight. When pulling, the pulled copper wire needs to bear the overall weight alone, so that when pulling, the copper wire will be deformed. The thin copper wire is relatively thin overall, and when pulled, the thin copper wire will break. Whether it is thin copper wire or thick copper wire stored on the surface of the winding drum, the weight will be heavier. When pulling and rotating, it will rotate due to inertia, and the copper wire cannot be quantitatively extracted, which will cause too much copper wire to fall off the surface of the winding drum.

[0015] Preferably, the outer surface of the limiting slider is movably overlapped on the inner wall surface of the extruded rectangular groove, and a swing arm is swingably connected to the outer surface of the limiting slider.

[0016] Preferably, a hollow soft block is fixedly connected to the inner wall surface of the swing arm, and an extrusion anti-slip pad is provided on the outer surface of the hollow soft block.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The feeding device of a copper wire cutting machine described in the present invention has the following characteristics: when the transverse movable bracket moves toward the direction of the transmission rod, the triangular push block on the bottom surface of the transverse movable bracket slides on the top surface of the swing block, and slides on the outer inclined surface of the triangular push block by means of the inclined groove, thereby squeezing the swing block toward the direction of the first indented groove. When the swing block retracts into the first indented groove, the surface of the triangular push block is no longer blocked by the swing block, so that the transmission plate does not move with the movement of the transverse movable bracket, and thus does not drive the transmission rod to rotate together;

[0019] 2. The feeding device of the copper wire cutting machine described in the present invention has the following characteristics: after the copper wire connecting cylinder catches the copper wire and moves in the opposite direction of the transmission rod, the vertical surface of the triangular pushing block will directly contact the diagonal corner of the swing block. At this time, the swing block will not retract under the elastic force of the elastic pushing wire, and the transmission plate will rotate under the push of the triangular pushing block. When the transmission plate rotates, it will drive the transmission crawler and the transmission rod to rotate. The length of the copper wire can be controlled according to the moving distance of the transverse moving bracket on the surface of the limit support plate. At this time, the transmission rod can be limited by the transmission crawler, which can greatly reduce the situation that the transmission rod will rotate too much due to the gravity inertia of the copper wire, thereby causing the copper wire to become too loose;

[0020] 3. The feeding device of the copper wire cutting machine described in the present invention disengages the copper wire from the surface of the transmission rod when the transmission rod rotates. As the copper wire slides inside the anti-slip inner liner, it moves along the raised end of the downward-pressing swing arm. The downward-pressing swing arm squeezes the elastic wire, thereby greatly reducing the friction between the arc-shaped squeezing block and the copper wire, allowing the copper wire to be quickly withdrawn.

[0021] 4. The feeding device of the copper wire cutting machine described in the present invention has the following features: when the copper wire stops being drawn, the copper wire will not move inside the anti-slip inner container without the action of external force. At this time, the downward pressing swing arm is elastically pressed downward by the elastic wire, so that the arc-shaped extrusion block on the bottom surface of the downward pressing swing arm can be tightly attached to the outer surface of the copper wire. When the copper wire moves in the opposite direction, the arc-shaped extrusion block is pushed by the elastic wire and the external force is blocked, which can effectively reduce the copper wire from moving back;

[0022] 5. The feeding equipment of a copper wire cutting machine described in the present invention, when the copper wire connecting tube is connected to the outer surface of one end of the copper wire, and one end of the copper wire is overlapped with the surface of the limit slider, the small hydraulic rod is used to pull back the limit slider. When the limit slider moves into the extrusion rectangular groove, the surface of one end of the copper wire connecting tube is squeezed against the positioning surface of the swing arm. At this time, the extrusion anti-slip pad on the inner wall of the swing arm is squeezed and fitted on the surface of the copper wire, increasing the friction and anti-slip force between the copper wire and the copper wire. At the same time, the hollow soft block is deformed under the extrusion of the extrusion anti-slip pad, so that the swing arm can clamp copper wires of different calibers.

DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0035] like Figures 1 to 4 As shown, a feeding device of a copper wire cutting machine according to an embodiment of the present invention comprises a triangular support frame 11, a transverse movable support frame 12, and a pull-out movable plate 111 movably overlapped on the outer surface of the bottom of the transverse movable support frame 12, a limited support plate 112 is fixedly installed on the top surface of the pull-out movable plate 111, a transmission rod 115 is provided on the top surface of the triangular support frame 11, a copper wire 116 is movably sleeved on the outer surface of the transmission rod 115, a plurality of groups of transmission shafts 113 are provided on the outer surfaces of both ends of the transmission rod 115, a transmission track 114 is movably sleeved on the outer surface of the transmission shaft 113, and a transmission disc 117 is provided on the inner wall surface of the other end of the transmission track 114;

[0036] A triangular pushing block a2 is provided on the bottom surface of the transversely movable bracket 12, and an indented groove c1 is provided on the outer surface of the transmission disk 117. A swing block c2 is swingably connected to the inner wall surface of the indented groove c1, and an elastic pushing wire c3 is fixedly connected to the inner wall surface of the indented groove c1. The other end of the elastic pushing wire c3 is fixedly connected to the outer surface of the swing block c2, and one end of the swing block c2 is movably connected to the surface of the triangular pushing block a2. An inclined groove c4 is provided on the outer surface of the swing block c2.

[0037] When the lateral movable bracket 12 slides on the surface of the position-limiting support plate 112, the copper wire connecting tube 121 is used to clamp and extract the copper wire 116 inside the lateral sleeve 131, and the lateral movable bracket 12 slides back and forth on the surface of the position-limiting support plate 112;

[0038] When the lateral movable bracket 12 moves toward the direction of the transmission rod 115, as shown in FIG. Figure 4 As shown, the triangular push block a2 on the bottom surface of the transverse movable bracket 12 slides on the top surface of the swing block c2 and slides on the outer inclined surface of the triangular push block a2 using the inclined groove c4, squeezing the swing block c2 toward the inward groove c1. When the swing block c2 retracts into the inward groove c1, the surface of the triangular push block a2 is no longer blocked by the swing block c2, so that the transmission plate 117 does not move with the movement of the transverse movable bracket 12, and thus does not drive the transmission rod 115 to rotate together.

[0039] When the copper wire connecting tube 121 is clamped with the copper wire 116 and moves in the opposite direction of the transmission rod 115, the vertical surface of the triangular push block a2 will directly contact the diagonal corner of the swing block c2. At this time, the swing block c2 will not retract under the elastic force of the elastic push wire c3. Figure 3 As shown, the transmission disc 117 is rotated under the push of the triangular push block a2. When the transmission disc 117 rotates, the transmission belt 114 and the transmission rod 115 are driven to rotate. The length of the copper wire can be controlled according to the moving distance of the transverse movable bracket 12 on the surface of the limit support plate 112. At this time, the transmission rod 115 is limited by the transmission belt 114, which can greatly reduce the excessive rotation of the transmission rod 115 due to the gravity inertia of the copper wire 116, thereby causing the copper wire 116 to become too loose.

[0040] like Figures 3 to 6 As shown, a limited overlap plate a1 is provided on the bottom surface of the transverse movable bracket 12, and the outer surface of the limited overlap plate a1 is movably overlapped on the outer surface of the transmission plate 117. An L-shaped support arm plate 118 is provided on the outer surface of the transmission shaft 113, and a triangular support frame 11 is fixedly connected to the outer surface of the L-shaped support arm plate 118. A support column 13 is fixedly installed on the top surface of the triangular support frame 11, and a transverse sleeve 131 is provided on the inner side wall of the top end of the support column 13. An anti-slip liner 132 is provided on the inner side wall of the transverse sleeve 131, and the inner side wall of the anti-slip liner 132 is movably It is movably sleeved on the outer surface of the copper wire 116, and an indented groove 133 is provided at the top edge of the anti-slip inner liner 132 and at the joint of the horizontal sleeve 131. A downward-pressing swing arm 134 is fixedly installed on the top inner wall of the horizontal sleeve 131, and an elastic wire 135 is fixedly connected to the top surface of the downward-pressing swing arm 134. The other end of the elastic wire 135 is fixedly connected to the top surface of the downward-pressing swing arm 134, and an arc-shaped extrusion block 136 is fixedly connected to the bottom surface of the downward-pressing swing arm 134. The outer surface of the arc-shaped extrusion block 136 is movably overlapped on the outer surface of the copper wire 116.

[0041] When the transmission rod 115 rotates, the copper wire 116 is detached from the surface of the transmission rod 115. When the copper wire 116 slides inside the anti-slip liner 132, the copper wire 116 moves along the raised end of the downward-pressing swing arm 134. At this time, the downward-pressing swing arm 134 squeezes the elastic wire 135, thereby greatly reducing the friction between the arc-shaped squeezing block 136 and the copper wire 116, so that the copper wire 116 can be quickly withdrawn.

[0042] When the copper wire 116 stops being drawn out, the copper wire 116 will not move inside the anti-slip liner 132 without the action of external force. At this time, the elastic wire 135 cooperates to elastically press down the downward swing arm 134, so that the arc-shaped extrusion block 136 on the bottom surface of the downward swing arm 134 can fit tightly against the outer surface of the copper wire 116. When the copper wire 116 moves in the opposite direction, the arc-shaped extrusion block 136 is pushed by the elastic wire 135, and the obstruction of external force can effectively reduce the situation where the copper wire 116 moves back.

[0043] like Figures 7 to 9 As shown, a copper wire connecting tube 121 is provided on the inner wall surface of the transverse movable bracket 12, and a guiding liner layer 122 is provided on the inner wall surface of the copper wire connecting tube 121. An extrusion rectangular groove 123 is provided at one end of the guiding liner layer 122 and located inside the copper wire connecting tube 121. A small hydraulic rod 124 is provided on the inner wall surface of the guiding liner layer 122, and a limiting slider 125 is fixedly connected to the output end of the small hydraulic rod 124. The outer surface of the limiting slider 125 is movably overlapped on the inner wall surface of the extrusion rectangular groove 123. A swing arm 126 is swingably connected to the outer surface of the limiting slider 125, and a hollow soft block 127 is fixedly connected to the inner wall surface of the swing arm 126. An extrusion anti-slip pad 128 is provided on the outer surface of the hollow soft block 127.

[0044] When the copper wire connecting tube 121 is docked to the outer surface of one end of the copper wire 116, and one end of the copper wire 116 is overlapped with the surface of the limit slider 125, the small hydraulic rod 124 is used to pull back the limit slider 125. When the limit slider 125 moves into the extrusion rectangular groove 123, one end surface of the copper wire connecting tube 121 is squeezed against the positioning surface of the swing arm 126. At this time, the extrusion anti-slip pad 128 on the inner wall of the swing arm 126 is squeezed and fitted on the surface of the copper wire 116, increasing the friction and anti-slip force between the copper wire 116 and the copper wire 116. At the same time, the hollow soft block 127 is deformed under the extrusion of the extrusion anti-slip pad 128, so that the swing arm 126 can clamp copper wires 116 of different calibers.

[0045] Working Principle: When the transverse movable bracket 12 moves toward the transmission rod 115, the triangular push block a2 on the bottom surface of the transverse movable bracket 12 slides on the top surface of the swing block c2 and slides on the outer inclined surface of the triangular push block a2 using the inclined groove c4, squeezing the swing block c2 toward the inward groove c1. When the swing block c2 retracts into the inward groove c1, the surface of the triangular push block a2 is no longer blocked by the swing block c2, so that the transmission plate 117 does not move with the movement of the transverse movable bracket 12, and thus does not drive the transmission rod 115 to rotate.

[0046] When the copper wire connecting tube 121 is clamped with the copper wire 116 and moves in the opposite direction of the transmission rod 115, the vertical surface of the triangular push block a2 will directly contact the diagonal corner of the swing block c2. At this time, the swing block c2 will not retract under the elastic force of the elastic push wire c3. Figure 3 As shown, the transmission disc 117 is rotated under the push of the triangular push block a2. When the transmission disc 117 rotates, the transmission track 114 and the transmission rod 115 are driven to rotate. The length of the copper wire can be controlled according to the distance moved by the transverse movable bracket 12 on the surface of the limit support plate 112. At this time, the transmission rod 115 is limited by the transmission track 114, which can greatly reduce the excessive rotation of the transmission rod 115 due to the gravity inertia of the copper wire 116, thereby causing the copper wire 116 to become too loose.

[0047] When the transmission rod 115 rotates, the copper wire 116 is detached from the surface of the transmission rod 115. When the copper wire 116 slides inside the anti-slip liner 132, the copper wire 116 moves along the raised end of the downward-pressing swing arm 134. At this time, the downward-pressing swing arm 134 squeezes the elastic wire 135, thereby greatly reducing the friction between the arc-shaped squeezing block 136 and the copper wire 116, so that the copper wire 116 can be quickly withdrawn.

[0048] When the copper wire 116 stops being drawn, the copper wire 116 will not move inside the anti-slip liner 132 without the action of external force. At this time, the elastic wire 135 cooperates with the downward-pressing swing arm 134 to elastically press downward, so that the arc-shaped extrusion block 136 on the bottom surface of the downward-pressing swing arm 134 can be tightly attached to the outer surface of the copper wire 116. When the copper wire 116 moves in the opposite direction, the arc-shaped extrusion block 136 is pushed by the elastic wire 135, and the external force can effectively prevent the copper wire 116 from moving back.

[0049] When the copper wire connecting tube 121 is docked to the outer surface of one end of the copper wire 116, and one end of the copper wire 116 is overlapped with the surface of the limit slider 125, the small hydraulic rod 124 is used to pull back the limit slider 125. When the limit slider 125 moves into the extrusion rectangular groove 123, one end surface of the copper wire connecting tube 121 is squeezed against the positioning surface of the swing arm 126. At this time, the extrusion anti-slip pad 128 on the inner wall of the swing arm 126 is squeezed and fitted on the surface of the copper wire 116, increasing the friction and anti-slip force between the copper wire 116 and the copper wire 116. At the same time, the hollow soft block 127 is deformed under the extrusion of the extrusion anti-slip pad 128, so that the swing arm 126 can clamp copper wires 116 of different calibers.
