Description

Technical Field

[0001] The utility model relates to the technical field of winding machines, in particular to a wire feeding device of a winding machine. Background Art

[0002] Winding machines are devices that wind linear objects onto specific workpieces. Commonly used winding machines wind enameled copper wires (winding inductor coils for electronic and electrical products), enameled aluminum wires, textile wires (winding spindles and coils for textile machines), heating wires for electric heating appliances, solder wires, wires, cables, etc. After the tin wires are processed, they are generally collected by rotating the material so that the wires are stacked in a circle.

[0003] At present, there is an existing wire feeding device for a winding machine (such as patent number: CN211945659U), which discloses a wire feeding device for a winding machine, including a connecting frame arranged on one side of the winding machine body and a plurality of guide wheels rotatably connected to the same side of the connecting frame and guiding the wire and at different heights, the plurality of guide wheels are coplanar and their axes are parallel to each other, a vertically arranged guide column is fixed at the bottom of the connecting frame through a fastening assembly, the guide column is located below the guide wheel, the guide column is vertically provided with a guide hole for guiding the wire, a connecting strip is fixed at the bottom of the connecting frame, the connecting strip is vertically provided with a limit cylinder for limiting the rotation amplitude of the wire through a fixing assembly, and the limit cylinder is located below the guide column. The utility model can limit the rotation amplitude of the wire, solve the entanglement problem of the wire caused by excessive rotation amplitude, and thus improve product quality.

[0004] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems:

[0005] 1. The existing device clamps the connection frame and the connection plate to the surface of the connection bar by fixing bolts and fixing nuts, so that the fixing bar and the limiting cylinder fixedly connected to the connection frame can slide on the connection bar to adjust the distance between the limiting cylinder and the disc. However, a problem with this fixing method is that each time the height of the limiting cylinder is adjusted, the tightness of the two bolts and nuts needs to be adjusted to reduce the force of the connection frame and the connection plate clamping the connection bar before the position of the limiting cylinder can be adjusted. Specific tools are required in the process, so the adjustment is troublesome, time-consuming and labor-intensive.

[0006] 2. The limiting cylinder of the existing device is not provided with an anti-drop mechanism, because the connecting frame and the connecting plate of the existing device are fixedly connected to the connecting strip by clamping. When the fixing bolts and the fixing nuts become loose due to long-term use or when the staff does not tighten the fixing nuts after adjusting the height of the limiting cylinder, the connecting frame and the connecting plate are likely to slide off the connecting strip, causing the limiting cylinder to fall, and the wires stacked inside the limiting cylinder will also be scattered on the ground, affecting the operation of the winding machine. Therefore, the fixing method of the limiting cylinder of the existing device is poor, which can easily cause the limiting cylinder to fall to the ground, and the limiting cylinder of the existing device is not provided with an anti-drop mechanism. Utility Model Content

[0007] 1. Technical issues to be resolved

[0008] In view of the deficiencies of the prior art, the utility model provides a wire feeding device for a winding machine, which solves the technical problems that the height of the limiting cylinder of the prior device is difficult to adjust and is easy to fall off.

[0009] (II) Technical solution

[0010] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0011] A wire feeding device for a winding machine comprises a winding machine body and a limiting cylinder. The winding machine body is fixedly connected to a connecting frame, the connecting frame is fixedly connected to a wire feeding mechanism, the bottom of the connecting frame is fixedly connected to a limiting rod, and the side of the connecting frame away from the wire feeding mechanism is fixedly connected to a C-shaped plate.

[0012] Preferably: a docking hole is provided at the position where the connecting frame is fixedly connected to the C-shaped plate, two circles of thread grooves are provided inside the docking hole, and a through hole is provided on the C-shaped plate, and the docking hole is parallel to the through hole.

[0013] Preferably, the limiting cylinder is fixedly connected with a connecting plate, the connecting plate is provided with a sliding hole, a limiting rod is slidably sleeved in the sliding hole, and one end of the limiting rod away from the connecting frame is threadedly connected with the limiting block.

[0014] Preferably: one end of the connecting plate away from the limiting cylinder is fixedly connected to a fixing plate, the fixing plate is provided with a plurality of fixing holes, the fixing plate is integrally slidably connected between the C-shaped plate and the connecting frame, and one end of the fixing plate away from the connecting plate is fixedly connected to a handle.

[0015] Preferably: a plug is sleeved in the docking hole and the through hole, one end of the plug away from the docking hole is fixedly connected to a pull ring, and one end of the plug away from the pull ring is provided with an anti-falling thread, and the number of circles of the anti-falling thread is two.

[0016] Preferably, the plug is threadably connected to a thread groove provided in the docking hole via an anti-dropping thread.

[0017] (III) Beneficial effects

[0018] 1. When it is necessary to change the height of the limit cylinder, first support the bottom of the limit cylinder with one hand, then pull the pull ring and rotate the plug to separate the anti-falling thread from the thread groove of the docking hole, and then pull the pull ring to pull the plug out of the docking hole, the fixing hole and the through hole as a whole. At this time, the fixing plate as a whole can slide between the connecting frame and the C-shaped plate. The height of the fixing plate can be adjusted by supporting the limit cylinder or pulling the handle, thereby driving the height of the limit cylinder to be adjusted. After adjusting to the required position, the plug can be reinserted into the docking hole, the through hole and the corresponding fixing hole. The reason why the anti-falling thread is only provided with two circles is to facilitate the removal of the plug. The function of the anti-falling thread is only to prevent the plug from falling off easily, which solves the problem that the height of the limit cylinder of the existing device is not easy to adjust.

[0019] Second, when the plug falls off accidentally, the fixing plate will lose its obstruction and fall under the action of gravity, causing the limiting cylinder to fall as well. However, due to the restrictions of the limiting rod and the sliding hole, the limiting cylinder always opens upward during the falling process, and finally the connecting plate will be blocked by the limiting block, so that the limiting cylinder will not fall to the bottom, and the internal wires will not fall out due to the limiting cylinder, thus solving the problem of the limiting cylinder of the existing device being easy to fall.

[0026] The embodiment of the present application provides a wire feeding device for a winding machine, which effectively solves the problem that the height of the limiting cylinder of the existing device is difficult to adjust and is easy to fall off.

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that the height of the limit cylinder of the existing device is difficult to adjust and easy to fall. The overall idea is as follows:

[0028] In view of the problems existing in the prior art, the utility model provides a wire feeding device for a winding machine, comprising a winding machine body 1 and a limiting cylinder 5, the winding machine body 1 is fixedly connected to a connecting frame 2, the connecting frame 2 is fixedly connected to a wire feeding mechanism 7, the bottom of the connecting frame 2 is fixedly connected to a limiting rod 201, and the side of the connecting frame 2 away from the wire feeding mechanism 7 is fixedly connected to a C-shaped plate 3.

[0029] A docking hole 203 is provided at the position where the connecting frame 2 is fixedly connected to the C-shaped plate 3 . Two circles of thread grooves are provided inside the docking hole 203 . A through hole 301 is provided on the C-shaped plate 3 . The docking hole 203 is parallel to the through hole 301 .

[0030] The limiting cylinder 5 is fixedly connected with a connecting plate 501 . The connecting plate 501 is provided with a sliding hole 502 . The limiting rod 201 is slidably sleeved in the sliding hole 502 . One end of the limiting rod 201 away from the connecting frame 2 is threadedly connected with the limiting block 202 .

[0031] One end of the connecting plate 501 away from the limiting tube 5 is fixedly connected to a fixing plate 6, which has a plurality of fixing holes 601. The fixing plate 6 is integrally slidably connected between the C-shaped plate 3 and the connecting frame 2. One end of the fixing plate 6 away from the connecting plate 501 is fixedly connected to a handle 602.

[0032] The docking hole 203 and the through hole 301 are both sleeved with a plug 4, one end of the plug 4 away from the docking hole 203 is fixedly connected with a pull ring 401, and the end of the plug 4 away from the pull ring 401 is provided with an anti-falling thread 402, and the number of circles of the anti-falling thread 402 is two.

[0033] The plug 4 is threadably connected to the thread groove provided in the docking hole 203 via the anti-dropping thread 402 .

[0034] When the height of the limiting cylinder 5 needs to be changed, first support the bottom of the limiting cylinder 5 with one hand, then pull the pull ring 401 to rotate the plug 4 to separate the anti-falling thread 402 from the thread groove of the docking hole 203, and then pull the pull ring 401 to pull the plug 4 out of the docking hole 203, the fixing hole 601 and the through hole 301 as a whole. At this time, the fixing plate 6 as a whole can slide between the connecting frame 2 and the C-shaped plate 3. The height of the fixing plate 6 can be adjusted by supporting the limiting cylinder 5 or pulling the handle 602, thereby driving the height of the limiting cylinder 5 to be adjusted. After adjusting to the required position, the plug 4 can be reinserted into the docking hole 203, the through hole 301 and the corresponding fixing hole 601. The reason why the anti-falling thread 402 is only provided with two circles is to facilitate the removal of the plug 4. The function of the anti-falling thread 402 is only to prevent the plug 4 from falling off easily, thereby solving the problem that the height of the limiting cylinder 5 of the existing device is not easy to adjust.

[0035] Working principle:

[0036] The first step is, when it is necessary to change the height of the limiting cylinder 5, first support the bottom of the limiting cylinder 5 with one hand, then pull the pull ring 401 to rotate the plug 4 to separate the anti-falling thread 402 from the thread groove of the docking hole 203, and then pull the pull ring 401 to pull the plug 4 out of the docking hole 203, the fixing hole 601 and the through hole 301 as a whole. At this time, the fixing plate 6 as a whole can slide between the connecting frame 2 and the C-shaped plate 3. The height of the fixing plate 6 can be adjusted by supporting the limiting cylinder 5 or pulling the handle 602, thereby driving the height of the limiting cylinder 5 to be adjusted. After adjusting to the required position, the plug 4 can be reinserted into the docking hole 203, the through hole 301 and the corresponding fixing hole 601. The reason why the anti-falling thread 402 is only provided with two circles is to facilitate the removal of the plug 4, and the function of the anti-falling thread 402 is only to prevent the plug 4 from falling off easily.

[0037] In the second step, when the plug 4 accidentally falls off, the fixing plate 6 loses its obstruction and falls under the action of gravity, thereby causing the limiting cylinder 5 to fall as well. However, due to the restrictions of the limiting rod 201 and the sliding hole 502, the limiting cylinder 5 always opens upward during the falling process, and finally the connecting plate 501 is blocked by the limiting block 202, so that the limiting cylinder 5 will not fall to the bottom, and the wire inside will not be overturned by the limiting cylinder 5.

[0038] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
