Description

Technical Field

[0001] The utility model relates to a wire pay-off anti-breaking device, in particular to a wire pay-off anti-breaking device for an enameled wire machine. Background Art

[0002] Enameled wire is a kind of electric wire, which is an electric wire made of conductive metal wires such as copper wires or aluminum wires after being stretched and then insulated, and is often used for manufacturing electrical equipment such as motors and transformers. The wire cores of the existing enameled wires are usually wound on a bobbin, and the wire cores on the bobbin are evenly paid off together with a wire drawing machine by an enameled wire machine. When being paid off, the wire cores on the bobbin will swing, and knots and twists are likely to occur between adjacent wire cores, and it is easy to cause the wire cores to break. Content of the Utility Model

[0003] The purpose of the utility model is to provide a wire pay-off anti-breaking device for an enameled wire machine. It can avoid phenomena such as knotting and twisting of wire cores and reduce the occurrence of wire breaking.

The sleeve consists of multiple cylinders with continuously increasing radii. An arc-shaped guide seat with continuously increasing height from the inside to the outside is provided at the upper end of the cylinder. A guide structure for enabling relative movement between the cylinders is provided between the cylinders. A support seat for supporting the sleeve is provided outside the lower end of the sleeve, and an anti-collision sleeve is provided on the inner wall of the cylinder.

[0005] In the aforesaid wire pay-off anti-breaking device for an enameled wire machine, the guide structure includes a sliding seat provided on the inner wall of the outer cylinder of adjacent cylinders and a guide strip provided on the outer wall of the inner cylinder of adjacent cylinders; a matching groove corresponding to the guide strip is provided in the sliding seat, a first positioning hole is provided on the guide strip, a second positioning hole corresponding to the first positioning hole is provided in the sliding seat, and a third positioning hole corresponding to the first positioning hole is provided on the side wall of the cylinder.

[0006] In the aforesaid wire pay-off anti-breaking device for an enameled wire machine, the support seat includes a connecting plate attached to the outer wall of the innermost cylinder, a horizontally arranged bottom support is provided at the lower end of the connecting plate, and a card slot corresponding to the cylinder is provided at the upper end of the bottom support.

[0007] Compared with the prior art, the utility model isolates each wire core by setting a telescopable sleeve. The wire core will hit the anti-collision sleeve. By setting the anti-collision sleeve, the damage to the wire core during impact and the noise generated by the impact are reduced, and the setting of the guide structure can improve the applicability and make the use more reliable.

Specific embodiments

[0011] The present utility model will be further described below in conjunction with the drawings and embodiments, but it shall not be used as a basis for restricting the present utility model.

[0012] Embodiment. An anti-breaking device for wire pay-off of an enameled wire machine table is configured as Figure 1-2 shown, including a telescopable sleeve 1 that can move up and down. The sleeve 1 consists of a plurality of cylinders 8 with continuously increasing radii. An arc-shaped guide seat 2 with continuously increasing height from the inside to the outside is provided at the upper end of the cylinder 8. A guiding structure is provided between the cylinders 8 to enable relative movement between the cylinders 8. A support base 3 for supporting the sleeve 1 is provided outside the lower end of the sleeve 1, and an anti-collision sleeve 4 is provided on the inner wall of the cylinder 8.

[0013] The guiding structure includes a sliding seat 5 provided on the inner wall of the outer cylinder 8 adjacent to the adjacent cylinders 8 and a guide bar 6 provided on the outer wall of the inner cylinder 8 adjacent to the adjacent cylinders 8. A mating groove 7 corresponding to the guide bar 6 is provided in the sliding seat 5. A first positioning hole 9 is provided on the guide bar 6, a second positioning hole 10 corresponding to the first positioning hole 9 is provided in the sliding seat 5, and a third positioning hole 16 corresponding to the first positioning hole 9 is provided on the side wall of the cylinder 8.

[0014] The support base 3 includes a connecting plate 11 that fits against the outer wall of the innermost cylinder 8. A horizontally arranged bottom support 12 is provided at the lower end of the connecting plate 11, and a clamping groove 13 corresponding to the cylinder 8 is provided at the upper end of the bottom support 12.

[0015] Principle of the present utility model: When in use, the present application is sleeved on the outer side of the bobbin, and then the wiring of the wire core on the bobbin is completed. Then, according to the wire releasing height of the machine table, the cylinder 8 is pulled up to make the height of the sleeve match the wire releasing height of the machine table. Under the cooperation of the sliding seat 5 and the guiding strip 6, the outer cylinder 8 can move up and down relative to the inner cylinder 8, and is locked by passing a fastener through the first positioning hole 9, the second positioning hole 10 and the third positioning hole 16. The fastener can adopt components such as screws and positioning pins. An arc-shaped guiding seat 2 is provided at the upper end of the cylinder 8 to prevent the wire released from the bobbin of the enameled wire machine table from hitting the edge of the cylinder when the wire is released, resulting in the wire core being cut. The setting of the anti-collision sleeve 4 can reduce the damage to the wire core during impact and reduce the noise generated by the impact. In order to prevent the sleeve 1 from tilting during wire release, a support seat 3 is provided outside the lower end of the sleeve 1, which can support the sleeve 1. That is, during the up and down movement of the cylinder 8, the support effect will not be affected, and the reliability is better. The setting of the card slot in the support seat 3 enables the cylinder 8 to be stuck in the card slot 13 when the cylinder 8 is not lifted, and the stability is good.
