Description

Technical Field

[0001] The present application belongs to the technical field of mica winding mechanisms and relates to a cable winding machine. Background Art

[0002] Cable mica winding mechanism and wrapping machine is a kind of efficient and automated insulation material processing equipment. The mechanism mainly includes supporting bottom plate, supporting main rod, connecting shaft, driven wheel, mica tape winding shaft, servo motor and driving wheel, among which the servo motor drives the driving wheel, drives the driven wheel and connecting shaft to rotate through the transmission belt, and then realizes the winding of mica tape. The wrapping machine rotates the turntable to wrap the mica tape and other insulating materials on the core wire of the cable according to a certain pattern. It has a variety of wrapping forms such as single layer, double layer, triple layer, and concentric wrapping.

[0003] When the existing wrapping machine wraps the cable with mica tape, the mica tape will exert a pulling force on the cable away from the axis, causing the cable to shake continuously as the mica tape is wound, shifting its axis position, so that the mica tape cannot be evenly wound on the cable.

[0004] On the one hand, the insulation performance of the part not wrapped by the mica tape will be reduced. On the other hand, the part wrapped by the mica tape for multiple times will make the thickness of the final finished cable uneven, which does not meet the national standard GB / T3048-2019. Summary of the invention

[0005] The purpose of the present invention is to solve the problem in the prior art that when a wrapping machine wraps mica tape around a cable, the cable shakes continuously along with the winding of the mica tape, and the mica tape cannot be evenly wound around the cable.

[0006] In order to achieve the above-mentioned purpose, the present application proposes a cable winding machine, comprising: a work table; a main shaft and a limit shaft arranged on the symmetrical side walls of the work table; a hollow tube arranged between the main shaft and the limit shaft and a wire groove penetrating the side wall of the hollow tube, wherein the main shaft and the limit shaft are coaxially arranged, one end of the hollow tube is connected to the output end of the main shaft, and there is a gap between the other end of the hollow tube and the end of the limit shaft, and the wire groove is parallel to the axis of the hollow tube.

[0007] In the winding mechanism and wrapping machine in the prior art, the cable directly passes through the main shaft and the limit shaft, and the mica tape is overlapped on the cable and continuously wrapped around the surface of the cable as the cable moves forward. However, since the cable is constantly shaking as the mica tape is wound, the mica tape cannot be evenly wound around the cable.

[0008] The cable mica winding mechanism and the wrapping machine of the present application are provided with a hollow tube with a wire groove between the main shaft and the limiting shaft. After the cable passes through the hollow tube, a point on the cable is selected, the point is pulled out of the hollow tube through the wire groove, and the beginning of the mica tape is wrapped around the point as the initial overlapping point, and then the cable and the mica tape are tightened respectively. In the process of the cable moving forward, since only the overlapping point is exposed on the outside of the hollow tube, the rest of the cable is confined in the hollow tube, thereby effectively limiting the shaking of the cable during the mica tape winding process, and solving the problem in the prior art that the mica tape cannot be evenly wound around the cable when the wrapping machine wraps the mica tape around the cable.

[0009] Furthermore, in order to facilitate the fixation of the mica tape reel, a mica tape mounting frame is mounted on the main shaft.

[0010] Furthermore, in order to facilitate the installation of the positioning frame, a mounting plate is provided on the end surface of the mica tape mounting frame close to the limiting shaft; and a plurality of positioning pins are evenly distributed on the circumference of the end surface of the mounting plate close to the limiting shaft.

[0011] Furthermore, in order to facilitate the installation of the positioning frame and the third wire wheel, a positioning frame is arranged on the mounting plate, and the positioning frame includes: triangular support frames symmetrically distributed on both sides of the main shaft; a cross bar symmetrically arranged on the bottom edge of the triangular support frame and away from the end surface of the mounting plate; and an L-shaped bracket is arranged on the cross bar.

[0012] Furthermore, in order to ensure that the cross bar is accurately installed on the triangular support frame and facilitate the adjustment of the position of the third wire wheel, a number of positioning bolt holes are provided at the part where the cross bar connects with the triangular support frame; an adjustment groove is provided at the part where the cross bar extends beyond the triangular support frame; and the L-shaped bracket is fixed in the adjustment groove by bolts.

[0013] Furthermore, in order to limit the extension direction of the mica tape, two first wire pulleys are symmetrically installed on the side end surface of the mica tape mounting frame: two wire pulley mounting frames are symmetrically installed on the circumference of the mounting plate close to the end surface of the limiting shaft; a second wire pulley is arranged on the wire pulley mounting frame; and a third wire pulley is arranged on the L-shaped bracket.

[0014] Furthermore, in order to ensure that the same overlapping surface is always maintained when the mica tape is wrapped around the cable, the axes of the second wire pulley and the third wire pulley are parallel.

[0015] The beneficial effects of this application are:

[0016] 1. The cable mica winding mechanism and the wrapping machine of the present application are provided with a hollow tube with a wire groove between the main shaft and the limit shaft. After the cable passes through the hollow tube, a point on the cable is selected, the point is pulled out of the hollow tube through the wire groove, and the beginning of the mica tape is wrapped around the point as the initial overlapping point, and then the cable and the mica tape are tightened respectively. In the process of the cable moving forward, since only the overlapping point is exposed on the outside of the hollow tube, the rest of the cable is confined in the hollow tube, thereby effectively limiting the shaking of the cable during the mica tape winding process, and solving the problem in the prior art that the mica tape cannot be evenly wound around the cable when the wrapping machine is wrapping the cable with mica tape.

[0017] 2. The mounting plate of the present application is provided with a positioning pin, and a triangular support frame is provided on the positioning frame. The positioning frame can be installed by simply aligning the opening on the top corner of the triangular support frame with the positioning pin and fixing it with a nut. At the same time, the triangular structure makes the support frame more stable.

[0018] 3. The crossbar of the present application is provided with an adjustment slot, and the position of the third wire wheel can be adjusted by changing the position of the L-shaped bracket in the adjustment slot, thereby adjusting the angle of the mica tape wrapped around the cable.

[0019] 4. The present application is provided with a first wire wheel, a second wire wheel and a third wire wheel. After the mica tape is tightened, the wide surface is always in contact with the wire wheel, so that the mica tape does not deviate when winding the cable. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will be combined with the attached Figures 1 to 3 The embodiments of the technical solution of the present application are described in detail. The following embodiments are only used to more clearly illustrate the technical solution of the present application, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application. In addition, the technical features involved in each embodiment of the present application described below can be combined with each other as long as they do not conflict with each other.

[0033] Embodiment 1:

[0034] like Figures 1 to 3 A cable winding machine of the present application is illustrated. In order to effectively limit the shaking of the cable and achieve uniform winding, the cable mica winding mechanism and winding machine of the present application are provided with a main shaft 2 and a limit shaft 3 on the work surface 1, and the two are arranged coaxially. A hollow tube 4 with a wire groove 41 is installed between the main shaft 2 and the limit shaft 3. After the cable passes through the hollow tube 4, a point on the cable is selected, and the point is pulled out of the hollow tube through the wire groove 41, and the beginning of the mica tape is wound around the point as the initial overlap point. Subsequently, the cable and the mica tape are tightened respectively, and the overlap position of the mica tape and the cable can be determined.

[0035] Furthermore, in the process of wrapping the cable with the mica tape, the mica tape mounting frame 5 drives the mounting plate 6 and the positioning frame 7 to rotate, thereby driving the hollow tube 4 to rotate, and at the same time, the cable continues to move forward, and the mica tape is wrapped.

[0036] Furthermore, during the advancement of the cable, since only the overlapping point passes through the wire trough 41 and is exposed outside the hollow tube 4, and the rest of the cable is confined in the hollow tube 4, the shaking range of the cable is limited to the hollow tube 4. At the same time, the overlapping point of the cable is outside the hollow tube 4, so when the cable passes through the wire trough 41, it is further restricted by the inside of the wire trough 41, thereby effectively limiting the shaking of the cable during the mica tape winding process, ensuring that the mica tape can be tightly and evenly wrapped around the cable, thereby improving the insulation performance of the cable and the quality of the finished product.

[0037] Embodiment 2:

[0038] Please refer to Figure 3 In order to facilitate the fixation of the mica tape reel and the installation of the positioning frame, the present application sets a mica tape mounting frame 5 on the main shaft 2, and sets a mounting plate 6 on the end surface of the mica tape mounting frame 5 close to the limiting shaft 3.

[0039] Furthermore, a plurality of positioning pins 61 are evenly distributed on the circumference of the end surface of the mounting plate 6. At the same time, the positioning frame 7 includes triangular support frames 71 symmetrically distributed on both sides of the main shaft 2. Holes are opened on the top corners of the triangular support frames 71, which can be fixed with nuts after aligning with the positioning pins 61. This design not only simplifies the installation process, but also improves the stability of the entire mechanism. The triangular support structure makes the positioning frame more stable and can withstand greater tension and pressure, thereby ensuring the stability and uniformity of the mica tape during the winding process.

[0040] Embodiment three:

[0041] Please refer to Figure 1 and Figure 3 In order to achieve flexible adjustment of the position of the third wire wheel 74, a cross bar 72 is provided on the positioning frame 7 of the present application. The portion where the cross bar 72 connects with the triangular support frame 71 is provided with several positioning bolt holes 721, which is convenient for accurate installation. The cross bar 72 can be fixed on the triangular support frame 71 by simply screwing the bolt into the bolt hole 721 and making the end of the bolt bear against the end surface of the triangular support frame 71.

[0042] Furthermore, an adjustment slot 722 is provided on the portion of the cross bar 72 that exceeds the triangular support frame 71 , and the L-shaped bracket 73 can be fixed at different positions in the adjustment slot 722 by bolts.

[0043] Specifically, if the L-shaped bracket moves toward the end away from the triangular support frame 71, the overlap angle between the mica tape and the cable can be reduced, so that the mica tape can wrap around the cable more densely; on the contrary, if the L-shaped bracket moves toward the end close to the triangular support frame 71, the overlap angle between the mica tape and the cable can be increased, so that the mica tape can wrap around the cable more sparsely. This design allows the user to adjust the position of the third wire wheel 74 according to actual needs, thereby adjusting the angle of the mica tape wrapping around the cable. This flexibility meets the needs of cables of different specifications and different windings, and improves the versatility and practicality of the device.

[0044] Embodiment 4:

[0045] Please refer to Figure 1 and Figure 3In order to ensure the stability of the extension direction of the mica tape and avoid deviation, the present application also provides a first wire wheel 51, a second wire wheel 63 and a third wire wheel 74. After the mica tape is tightened, its wide surface is always in contact with the wire wheel. This design ensures that the mica tape does not deviate when winding the cable and is always wound along a predetermined path. The first wire wheel 51 is located on the side end face of the mica tape mounting frame 5, and is used to guide the initial extension direction of the mica tape; the second wire wheel 63 is installed on the end face of the mounting plate 6 close to the limit shaft 3, and is used to further adjust the extension direction of the mica tape; the third wire wheel 74 is installed on the L-shaped bracket 73, and is used to finally determine the contact point between the mica tape and the cable. This multi-wire wheel design not only improves the stability of the mica tape extension, but also ensures the reliability and consistency of the winding quality.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
