Description

Technical Field

[0001] This application relates to the technical field of glass fiber production, and specifically relates to a split-type spliced head expanding piece for a wire drawing machine. Background Art

[0002] The expanding pieces of the wire drawing machine head are an essential part of the wire drawing machine equipment. They provide strong guarantees for the normal operation and efficient production of the wire drawing machine by stabilizing the wire drawing process, improving production efficiency, protecting the quality of the yarn, and enhancing the structural strength.

[0003] Nowadays, glass fiber wire drawing is developing towards large orifices and multiple draws. The head of the wire drawing machine is relatively long, and the expanding pieces used are also relatively long. Due to the influence of centrifugal force, the expanding pieces can only be made lightweight. However, after the long expanding pieces are made lightweight, their rigidity and straightness will inevitably be affected. After hardening, they are more likely to bend and deform, resulting in inconsistent opening sizes, which affects the slipping of the plastic winding cylinder, or bulging, causing faults inside the silk cake and affecting the subsequent unwinding. Moreover, it is very difficult to process the long expanding pieces. Utility Model Content

[0004] In view of this, this application provides a split-type spliced head expanding piece for a wire drawing machine to solve all or part of the technical problems described in the background art section of this application.

Concave sockets and convex plugs are respectively arranged at both ends of the expanding piece monomers. The plurality of expanding piece monomers are sequentially connected end to end through the insertion fit between the concave sockets and the convex plugs to form a split-type expanding piece.

[0007] Preferably, the cross-section of the expanding piece monomer is an I-shaped structure.

[0009] Preferably, the top of the locking portion is an arc-shaped surface, and the arc-shaped surface is adapted to the inner side surface of the winding cylinder on the wire drawing machine head.

[0015] Beneficial technical effects:

[0016] For the combined splicing type wire drawing machine head expanding piece claimed in this application, the design of connecting multiple sections of expanding pieces in series can achieve the light weight of the expanding pieces while avoiding the problems that the rigidity and straightness of the longer expanding pieces are affected after being lightened. Through the concave-convex connection at the splicing end of the expanding pieces, each expanding piece has both synchronous and self-adjusting functions, so that each plastic winding cylinder can receive an appropriate tension force.

[0025] 1310 - Contact surface. Specific Implementation Manner

[0026] Please refer to Figures 1-4, the split-type spliced expanding piece of the wire drawing machine head disclosed in this application includes several expanding piece monomers 10. Concave sockets 110 and convex plugs 120 are respectively arranged at both ends of the expanding piece monomer 10. Several expanding piece monomers 10 are sequentially connected end to end through the plug-in fit between the concave sockets 110 and the convex plugs 120 to form a split-type expanding piece.

[0027] The cross-section of the expanding piece monomer 10 is an I-shaped structure.

[0028] The expanding piece monomer 10 includes a snap-in portion 130, a locking portion 140, and a base portion 150 that connects the snap-in portion 130 and the locking portion 140 into one body; a clamping position adapted to the snap-in portion 130 is arranged on the aluminum rotating cylinder of the wire drawing machine head; the snap-in portion 130 is movably clamped in the clamping position adapted to the aluminum rotating cylinder on the wire drawing machine head; this movable clamping connection structure can prevent the split-type spliced expanding piece of the wire drawing machine head from falling off radially from the aluminum rotating cylinder.

[0029] The top of the locking portion 140 abuts against the inner side surface of the winding cylinder on the wire drawing machine head. The top of the locking portion 140 is an arc-shaped surface, and the arc-shaped surface is adapted to the inner side surface of the winding cylinder on the wire drawing machine head.

[0030] One side of the snap-in portion 130 close to the locking portion 140 is a contact surface 1310, and the shape of the contact surface 1310 is adapted to the corresponding surface of the clamping position of the aluminum rotating cylinder.

[0031] The shape of the contact surface 1310 can be a ramp surface, a flat surface or a stepped surface.

[0032] The split-type spliced expanding pieces of the wire drawing machine head are evenly distributed in a ring and are movably clamped on the aluminum rotating cylinder of the wire drawing machine head. A spring hole is arranged on one side of the aluminum rotating cylinder close to the split-type spliced expanding piece of the wire drawing machine head, and a expanding piece spring is accommodated in this spring hole. When the winding cylinder is sleeved on the aluminum rotating cylinder, the top of the locking portion 140 and the winding cylinder are tightly attached together through the tension of the expanding piece spring.

[0033] It also includes a first-section expanding piece monomer 20 and a last-section expanding piece monomer 30; the first-section expanding piece monomer 20 is located at the first end of the split-type expanding piece, and one end is provided with a concave socket 110; the last-section expanding piece monomer 30 is located at the last end of the split-type expanding piece, and one end is provided with a convex plug 120. The first-section expanding piece monomer 20 and the last-section expanding piece monomer 30 are detachably fixed to the end covers at both ends of the aluminum rotating cylinder.

[0034] The number of the expanding piece monomers 10 is at least two or more.

[0035] The combined and spliced expanding piece of the wire drawing machine head disclosed in this application is annularly distributed and movably clamped on the aluminum rotating cylinder of the wire drawing machine head. Cooperating with the expanding piece spring assembled on the aluminum rotating cylinder, the combined and spliced expanding piece of the wire drawing machine head is pushed outwards by the elastic force of the expanding piece spring, and the winding cylinder can be stably sleeved on the wire drawing machine head for operation. Since the multi-section expanding piece connection design is adopted, while achieving the light weight of the expanding piece, the problem that the rigidity and straightness of the longer expanding piece are affected after being light-weighted can be avoided. Through the concave-convex connection at the splicing end of the expanding piece, each expanding piece has both synchronous and self-adjusting functions, so that each plastic wire winding cylinder can receive an appropriate tension force.

[0036] The technical solutions and technical effects of this application have been elaborated in detail above in combination with the specification drawings and specific embodiments. It should be noted that those skilled in the art can also develop other embodiments on this basis; any simple deformation and equivalent replacement that do not deviate from the innovative concept of this application are covered by this application and belong to the protection scope of this patent.
