Description

Technical Field

[0001] The utility model relates to the technical field of enameled wire production equipment, in particular to a core wire pay-off device. Background Art

[0002] During the enameled wire coating process, the coiled core wire is unwound, dust and grease are cleaned from the core wire surface, and then the core wire is coated to ensure that the insulating varnish adheres firmly to the core wire surface. In the prior art, multiple core wires are typically simultaneously introduced into a cleaning device for cleaning. After cleaning, they are directly introduced into a drying device and a coating device. A payout device guides the core wires from the spool to the cleaning device. The core wires are directly guided from the spool to the cleaning device by several guide wheels. Due to the low tension of the core wire in the payout device, it is easy for the core wire to fall off the guide wheels, resulting in wire breakage and tangled wires, which greatly affects the efficiency of the enameled wire coating process. Utility Model Content

[0003] The utility model aims to provide a core wire pay-off device, which has the characteristics of smooth pay-off and improved coating efficiency of enameled wire.

[0004] To achieve this purpose, the present invention adopts the following technical solutions:

[0005] A core wire pay-off device comprises a guide frame, a spool mounting frame, a vertical guide wheel, a transverse guide wheel and an entrance guide wheel, wherein the spool mounting frame is located below the guide frame, and the vertical guide wheel, the transverse guide wheel and the entrance guide wheel are sequentially arranged on the guide frame;

[0006] The vertical guide wheel, the transverse guide wheel and the upstream adjacent portion of the inlet guide wheel are all provided with guide ceramic rings;

[0007] The guide porcelain ring is formed by winding a rod so that the guide porcelain ring has a gap for the core wire to enter.

[0008] In some embodiments, the tail end of the guide ceramic ring has a connecting rod with a thread.

[0009] In some embodiments, a vertical mounting plate is provided on the side of the guide frame body, and the vertical guide wheel and the corresponding guide ceramic ring are provided on the vertical mounting plate;

[0010] The vertical guide wheel is adjustable at the installation position of the vertical installation plate.

[0011] In some embodiments, the guide frame is provided with a mounting cross bar, the mounting cross bar has a first elongated hole, a connecting rod is installed in the first elongated hole of the mounting cross bar, the connecting rod has a second elongated hole, and the lateral guide wheel is installed in the second elongated hole.

[0012] In some embodiments, the guide ceramic ring corresponding to the transverse guide wheel is arranged in the first elongated hole through a mounting plate.

[0013] In some embodiments, the guide frame is provided with a plurality of the mounting cross bars, and the transverse guide wheels are respectively provided on both sides of the mounting cross bars, and the transverse guide wheels of the plurality of the mounting cross bars are staggered.

[0014] The end of the guide frame is provided with a plurality of inlet guide wheels arranged side by side, and each inlet guide wheel evenly corresponds to one guide porcelain ring.

[0015] In some embodiments, at least one of the mounting cross bars is provided with a guide cylinder, the guide cylinders of two adjacent mounting cross bars are positioned opposite each other, and a core wire passes through the vertical guide wheel, the transverse guide wheel, several of the guide cylinders and the entrance guide wheel in sequence.

[0016] The technical solution provided by the utility model may have the following beneficial effects:

[0017] Ceramic guide rings are positioned adjacent to the upper sides of each guide wheel to guide the core wire through the guide wheel, effectively preventing it from escaping.

DETAILED DESCRIPTION

[0022] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0023] The following combination Figures 1 to 3 , describing a core wire pay-off device according to an embodiment of the present utility model.

[0024] A core wire 01 pay-off device, comprising a guide frame 1, a spool mounting frame 2, a vertical guide wheel 3, a transverse guide wheel 4, and an inlet guide wheel 5, wherein the spool mounting frame 2 is located below the guide frame 1, and the vertical guide wheel 3, the transverse guide wheel 4, and the inlet guide wheel 5 are sequentially arranged on the guide frame 1;

[0025] A guide ceramic ring 6 is provided at the upstream adjacent positions of the vertical guide wheel 3, the transverse guide wheel 4 and the inlet guide wheel 5;

[0026] The guide porcelain ring 6 is formed by winding a rod, so that the guide porcelain ring 6 has a gap for the core wire 01 to enter.

[0027] The core wire 01 pay-off device of the present invention is provided with a guide ceramic ring 6 adjacent to the upper side of each guide wheel to guide the core wire 01 through the guide wheel, effectively preventing the core wire 01 from escaping from the guide wheel, thereby achieving the effect of smooth pay-off and improving the efficiency of enameled wire painting. The guide ceramic ring 6 is relative to the metal ring, and when the metal core wire 01 passes through the guide ceramic ring 6, the friction between the two will not produce sparks, thereby ensuring production safety. Moreover, the intersection of the guide ceramic ring 6 formed by winding a rod forms a gap for the core wire 01 to enter, and the core wire 01 is not easy to escape from the guide ceramic ring 6. The guide hole diameter of the guide ceramic ring is 6-12mm.

[0028] Specifically, after being unloaded from the spool, a core wire 01 passes through vertical guide wheels 3, transverse guide wheels 4, and inlet guide wheels 5 before entering the cleaning equipment. After being cleaned, the core wire 01 is dried and then enters the painting equipment. Guide ceramic rings 6 prevent the core wire 01 from slipping off the guide wheels, ensuring smooth unwinding and improving the painting efficiency of the enameled wire.

[0029] Preferably, the tail end of the guide ceramic ring 6 has a threaded connecting rod 61 to facilitate installation of the guide ceramic ring 6 on the guide frame 1, and the connecting rod 61 can make the guide hole of the guide ceramic ring 6 face the wheel surface of the guide wheel.

[0030] In one embodiment of the present invention, a vertical mounting plate 31 is provided on the side of the guide frame body 1, and the vertical guide wheel 3 and the corresponding guide ceramic ring 6 are provided on the vertical mounting plate 31; the installation position of the vertical guide wheel 3 on the vertical mounting plate 31 is adjustable. The vertical mounting plate 31 is used to realize the installation of the vertical guide wheel 3 and the corresponding guide ceramic ring 6, and facilitates guiding the core wire 01 to the transverse guide wheel 4. Specifically, the vertical mounting plate 31 is provided with a long hole, and the wheel axle of the vertical guide wheel 3 is installed in the long hole, so that the position of the vertical guide wheel 3 is adjustable, thereby facilitating the vertical guide wheel 3 to guide the core wire 01 to the transverse guide wheel 4.

[0031] Preferably, the guide frame 1 is provided with a mounting crossbar 11, which defines a first elongated hole 111. A connecting rod 12 is mounted in the first elongated hole 111 of the mounting crossbar 11. The connecting rod 6112 defines a second elongated hole 121, and the transverse guide wheel 4 is mounted in the second elongated hole 121. The connecting rod 6112 is positioned in the first elongated hole 111 by a screw, allowing the position of the connecting rod 12 in the first elongated hole 111 to be adjusted. The axle of the transverse guide wheel 4 is positioned in the second elongated hole 121, allowing the position of the transverse guide wheel 4 in the second elongated hole 121 to be adjusted, thereby aligning the positions of the vertical guide wheel 3, the transverse guide wheel 4, and the inlet guide wheel 5, thereby ensuring the combing and payout of the core wire 01. Exemplarily, the first elongated hole 111 extends from one end of the mounting crossbar 11 to the other end, allowing the mounting position of the transverse guide wheel 4 to be adjusted throughout the entire transverse range.

[0032] Furthermore, the guide ceramic ring 6 corresponding to the transverse guide wheel 4 is arranged in the first long hole 111 through the mounting plate 13. The installation structure of the transverse guide wheel 4 and its corresponding guide ceramic ring 6 is simple, and the position of the guide ceramic ring 6 can be adjusted so that the guide ceramic ring 6 remains corresponding to the transverse guide wheel 4.

[0033] In one embodiment of the present invention, the guide frame 1 is provided with a plurality of the mounting cross bars 11, and the transverse guide wheels 4 are respectively provided on both sides of the mounting cross bars 11, and the transverse guide wheels 4 of the plurality of the mounting cross bars 11 are staggered.

[0034] A plurality of inlet guide wheels 5 arranged side by side are provided at the end of the guide frame 1 , and each inlet guide wheel 5 evenly corresponds to one guide ceramic ring 6 .

[0035] In this embodiment, the arrangement of multiple mounting crossbars 11 allows multiple spools to be simultaneously paid out through a single guide frame 1. Multiple core wires 01 pass through offset transverse guide wheels 4 before being routed around inlet guide wheels 5, significantly improving payout efficiency. Multiple core wires 01 can be simultaneously paid out, cleaned, dried, and painted. Specifically, the multiple mounting crossbars 11 are parallel to one another, allowing multiple core wires 01 to simultaneously pass through multiple, parallel inlet guide wheels 5. As will be appreciated, inlet guide wheels 5 are located at the entrance of the cleaning device.

[0036] In one embodiment of the present invention, at least one of the mounting crossbars 11 is provided with a guide cylinder 7. The guide cylinders 7 of two adjacent mounting crossbars 11 are positioned opposite each other. A core wire 01 sequentially passes through the vertical guide wheel 3, the transverse guide wheel 4, a plurality of the guide cylinders 7, and the entrance guide wheel 5. After passing through the transverse guide wheel 4, the core wire 01 located upstream passes through the guide cylinder 7 on another mounting crossbar 11 and then bypasses the entrance guide wheel 5, thereby preventing multiple core wires 01 from becoming tangled.
