Description

Anti-clamping device for cable winder

Technical Field

The utility model belongs to the technical field of mechanical equipment technique and specifically relates to an anti-pinch device for cable winder is related to.

Background

The traditional process for manufacturing the enameled wire comprises paying off, cleaning, softening, painting, baking, lubricating and taking up. The finished bare wire produced in the previous drawing process (or the finished bare wire produced in the previous drawing process is paid off and then is drawn off by an online drawing machine) is paid off, then enters a cleaning system to clean floating oil and aluminum powder on the surface of the bare wire, enters a softening furnace to anneal, a flexible wire formed by annealing passes through a drying system, then enters a painting system to paint and then enters a drying furnace to bake, and the steps are repeated for a plurality of times, and then passes through a lubricating, collecting and wire arranging system to produce a product meeting certain standards.

The protection of the transmission part of the vertical wire rewinding machine of the existing multi-head low-speed enamelling machine is poor, when the enamelling machine is broken, the finished wire on the wire rewinding disc can slide down from the wire rewinding disc, often can slide to the transmission part of the wire rewinding machine and is wound on the transmission shaft, if the finished wire is not found and cleaned in time, the wire rewinding tension can be influenced when the wire is rewound next time, so that the finished enamelled wire is thinned, the product quality problem is caused, the enamelled wire also has the phenomenon of inconsistent color, even broken wires, particles and the product quality is unstable.

Therefore, a novel protection device for the transmission part of the wire rewinding machine must be developed, so that a finished wire is prevented from being wound on a wire rewinding shaft when the enamelling machine is broken, the wire rewinding machine has stable wire rewinding tension, and the product quality is guaranteed.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an anti-pinch device for cable rolling device in order to solve the defect that prior art exists.

In order to realize the purpose, the utility model discloses a technical scheme as follows:

the utility model provides an anti-pinch device for cable winder sets up the outside at the base lower extreme driving sleeve of admission machine, wherein, includes: the upper protective cover and the lower protective cover are integrally formed;

As a preferable technical scheme, the fastener is a hexagon socket end fastening screw or a triangle socket end fastening screw.

As a preferred technical scheme, the fastener is a countersunk hexagon socket head cap screw or a countersunk slotted screw.

Preferably, the diameter of the lower end of the upper shield is smaller than that of the lower shield, and a transition section is arranged between the upper shield and the lower shield.

As a preferable technical scheme, the section of the transition section is of an arc-shaped structure.

As a preferable technical scheme, a cover cap is arranged on the outer side of the fastener and used for shielding a threaded hole formed by the fastener so as to enhance the smoothness and the flatness of the upper protective cover and the lower protective cover.

Has the advantages that: simple structure, reasonable go up the surperficial level and smooth of protection casing and lower protection casing, adopt concave end holding screw or countersunk screw, avoided the screw cap to hang the waste silk, can prevent that the finished product line on the drum from twining on the transmission shaft when the broken string, guarantee to receive line tension stable, ensure product quality stable.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.

Example 1

Referring to fig. 1-2, an anti-pinch device for a cable winder is arranged on the outer side of a transmission shaft sleeve 2 at the lower end of a base 1 of a take-up machine and comprises: an upper protective cover 3 and a lower protective cover 4 which are integrally formed; wherein, the upper protective cover 3 is conical and is fixed on the side wall of the base 1 through a fastener 5; the lower protective cover 4 is cylindrical and is fixed on the side wall of the driving shaft sleeve 2 through a fastener 5; the fastener 5 of the utility model is a concave end fastening screw or a countersunk head screw. A general bolt or screw is a connecting member for connecting two objects, and a head of the general screw protrudes above a surface of the connected object to make the surface smooth. The countersunk head screw can sink to the lower surface to enable the surface to be flat, and a countersunk hole needs to be drilled at the corresponding position of the countersunk head for a hard object, so that the surface can be kept flat after the head of the countersunk head screw is installed. The concave end fastening screw has no head, and the head-free design is adopted to make the connected piece more beautiful and keep the surface flat. Therefore, when the wire is broken, the waste wire cannot be hung on the screw cap.

The fastening member 5 in this embodiment is a socket head cap screw or a socket head cap screw, and of course, the fastening member 5 may also be a countersunk socket head cap screw or a countersunk slotted screw. A cap 7 is provided on the outer side of the fastening member 5 to block the screw hole formed by the fastening member 5, so as to enhance the smoothness and flatness of the upper shield 3 and the lower shield 4.

The utility model discloses a diameter of going up 3 lower extremes of protection casing is less than the diameter of lower protection casing 4, has changeover portion 6 between last protection casing 3 and lower protection casing 4, and the cross-section of changeover portion 6 is the arc structure. By adopting the design, the surface between the upper protective cover 3 and the lower protective cover 4 is smooth, no sharp corner or burr is generated, and the waste wire can be effectively prevented from being clamped into the transmission shaft. Through the application of the transition section 6, the waste wire is easy to find and clean in time after being wound on the transition section 6.

Has the advantages that: simple structure, reasonable, go up the surperficial level and smooth of protection casing 3 and protection casing 4 down, adopt concave end holding screw or countersunk screw, avoided the screw cap to hang the waste silk, can prevent that the finished product line on the drum from twining on the transmission shaft when the broken string, guarantee to receive line tension stable, ensure product quality stable.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
