Description

The utility model relates to the textile industry, and more specifically to bobbin and bobbin holders, which provide centering and fixation of the bobbin in the desired position on the axis of the bobbin holder, in particular to unwinding equipment, and can be used in weaving in the industry of processing natural, artificial, synthetic , in particular carbon and glass fibers.

As the closest analogue, according to the presence of features similar to the essential features of the claimed utility model, the design of the bobbin holder is adopted [Patent No. 1234331 USSR MPK V65N 54/54 Bobbin holder of the winding machine /Komkov N.I., Gusev G.V., Nazarov V. I., Kalygin V.G. Applicant and patentee Moscow Order of the Red Banner of Labor Institute of Chemical Engineering and Sudogodsk fiberglass plant "Krasny Khimik", application No. 3854642/28-12, declared 06.12.1984; Published 05/30/1986] containing a hub and cantilevered along its side surface of the elastic petals for pressing against the bobbin under the action of centrifugal forces.

The disadvantage of this reel holder is the material of manufacture. The use of thermoplastic plastics and the injection molding method increase the cost of the product, in addition, the likelihood of getting a marriage of the entire batch of parts increases.

Also, the disadvantage of this device is the integrity of the structure, since if one elastic petal breaks, the entire device must be replaced.

Known reel holder, [Patent No. 2194663 RF IPC B65 54/547 Reel holder / Zakharov GV, Zakharov SV. Applicant and patent holder Ural Electrochemical Combine, application No. 2001111102/12, filed 20.04.2001; Published on 12/26/2002], containing a cylindrical body, on which an elastic clamping element is installed in the form of a helical coil spring, one end of which is connected to the body, the other - to the bushing. The clamping element is placed in a groove on the outer surface of the body. The bobbin is fixed on the bobbin holder by increasing the diameter of the clamping element under the action of centrifugal forces arising from the rotation of the bobbin holder. A strong connection of the bobbin with the bobbin holder in the indicated device is possible only when the bobbin holder reaches sufficiently high revolutions, when centrifugal forces can act on the helical coil spring, and with high tension forces of the wound thread. Under such conditions of winding and operation of the equipment, the shock load on the thread and its increased breakage are not excluded, which means that such a bobbin holder cannot be used for winding filamentary materials of low strength, because the thread will fall off the ends of the wound package under the influence of large tension forces. .

The disadvantage of the known reel holder is also its complex design.

The purpose of the utility model is to increase the reliability of the design and service life of the reel holder.

To achieve the specified technical result, the bobbin holder is assembled from three radial guides, rigidly fixed at both ends with triangular flanges. Thanks to this design, reliable fixation of the bobbin is achieved at low speeds of the bobbin holder and a small thread tension force.

All body elements are connected to each other with the help of technical grooves and / or protrusions, while the parts connected to each other are located perpendicular to each other.

Reliable connection of the bobbin with the bobbin holder is ensured by the interaction of the inner surface of the bobbin with three front support points and three rear wedge-shaped struts located on radial guides.

The proposed utility model can be manufactured by methods: laser and waterjet cutting, milling, as well as mechanical processing and 3D printing.

Various sheet materials can be used as the main body material, including: plastic, plywood, metal, and so on.

The reel holder is made of sheet material by laser cutting, which significantly reduces the cost of the utility model, increases the speed of creating body parts, and also ensures high accuracy and maintainability.

Maintainability is improved due to the prefabricated design of the bobbin holder body, due to the interchangeability of unified parts. If one of them fails, there is no difficulty in replacing or upgrading.

The proposed reel holder is illustrated in the drawings in Fig. 1-8:

Fig. 1 - shows a general view of the reel holder;

Fig. 2 - shows the front view of the reel holder;

Fig. 3-longitudinal section along A-A;

Fig. 4 shows view B of FIG. 3;

Fig. 5 - large flange;

Fig. 6 - small flange;

Fig. 7 - radial guide;

Fig. 8 - Longitudinal section of the bobbin holder and bobbin.

The body of the bobbin holder (Fig. 1) consists of two triangular flanges: large 1 (Fig. 5) and small 2 (Fig. 6), connected by three radial guides 3 (Fig. 7).

The large flange 1 is provided with three through rectangular grooves 9, in which the rear end of the radial guides 3 is placed.

The technical groove 10 is made to facilitate the assembly of the structure. Fastening of a small flange (Fig. 6) with radial guides (Fig. 7) is carried out using rectangular cutouts 12 and 13. Three front support points 4 and three rear wedge-shaped struts 5 are made on the outer surface of the radial guides. This design solution allows you to tightly fix the bobbin on the reel holder and greatly simplifies the structure of the structure. The radial guides (Fig. 7) of the bobbin holder (Fig. 3) are also equipped with a technical groove 11 intended for a fixing split washer 6 and additional washers 7 fixing it on both sides.

The work of the reel holder (Fig. 8) is carried out as follows.

The reel holder is placed on the axis of the reel holder 15, through the slots for axial rotation 8 located in the center of the large (Fig. 5) and small (Fig. 6) flanges. The bobbin 14 is mounted on the body of the bobbin holder up to the larger flange (Fig. 5). Three front support points 4 and three rear wedge-shaped spacers 5 touch the inner surface of the bobbin and hold it tightly, providing a fixation that prevents the bobbin from flying off the bobbin holder. The bobbin holder is fixed on its axis due to the locking split washer 6 and additional locking washers 7, which tightly hold the split washer 6 on both sides, thereby preventing it from rotating together with the bobbin holder. The design of the technical groove 11 (shown in Fig. 7) provides the convenience of installing the locking washers 6 and 7 on the axis of the bobbin holder 15.

The proposed device makes it possible to use it when rewinding any filamentous materials, since the possibility of manufacturing the body from sheet material and ease of assembly increases the reliability and service life of the structure.

The proposed device makes it possible to use it for rewinding not only low-strength filamentous materials, but also especially strong ones, providing a reliable connection between the bobbin and the bobbin holder, and the possibility of manufacturing the body from sheet material and ease of assembly reduces the cost, increases the reliability and service life of the structure. In particular, it provides convenience when installing the bobbin on the bobbin holder, the reliability of fixing its position and transmitting torque to the bobbin.
