[0019] The following will describe in detail the embodiments of the present utility model. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0020] All the features disclosed in this specification, or all the steps in the disclosed methods or processes, except for mutually exclusive features and / or steps, can be combined in any manner.

[0021] Any feature disclosed in this specification (including any additional claims, abstract, and drawings), unless specifically stated, can be replaced by other equivalent or alternative features with similar purposes. That is, unless specifically stated, each feature is only an example of a series of equivalent or similar features.

[0022] As Figure 1 、 Figure 2 and Figure 3 As shown, a pre-shrinking and shaping machine for producing webbing of the present utility model includes a housing 1. An open-sided shaping channel is formed inside the housing 1. Arc-shaped troughs 5 communicating with the shaping channel are curvedly formed on both the top and bottom surfaces of the housing 1. Installation grooves 2 are provided on both the top and bottom surfaces of the shaping channel. Flexible electric heating films 3 are provided in the installation grooves 2. Supports 10 are arranged in the arc-shaped troughs 5. An extrusion cylinder 11 is installed inside the support 10. The middle parts of the flexible electric heating films 3 are all extruded by the extrusion cylinder 11 and are relatively arched out.

[0023] In this embodiment, installation parts are convexly formed on the outer side surfaces of the arc-shaped troughs 5. Screw holes communicating with the arc-shaped troughs 5 are provided on the installation parts. Bearings are embeddedly installed on the outer side surfaces of the supports 10 opposite to the screw holes. Screws 9 are threadedly connected in the screw holes. One ends of the screws 9 are installed in the inner rings of the bearings, and the other ends are arranged outside and are all provided with handwheels 7.

[0024] In this embodiment, a plurality of positioning holes are provided on the outer side surfaces of the arc-shaped troughs 5. Positioning rods 6 are provided in the positioning holes. One ends of the positioning rods 6 are all installed on the outer side surfaces of the supports 10.

[0025] In this embodiment, elastic sheets 4 are installed at both ends of the flexible electric heating film 3. The other ends of the elastic sheets 4 are all installed on the inner wall surfaces of the installation grooves 2. During the process of the extrusion cylinder moving inward, it can squeeze the flexible electric heating film inward, and the elastic sheets at both ends of the flexible electric heating film will be pulled, enabling the middle of the flexible electric heating film to arch out smoothly. Conversely, after the extrusion cylinder moves outward, the flexible electric heating film can be straightened again through the rebound of the elastic sheets, so as to adapt to webbing of different widths.

[0026] In this embodiment, a plurality of fixing seats 8 are installed on the bottom surface of the housing 1. A plurality of fixing holes are provided on the fixing seats 8.

[0027] In this embodiment, the housing 1 is made of plastic material. The poor thermal conductivity of the plastic enables the heat generated by the flexible electric heating film to act inside the shaping channel to heat the passing webbing.

[0028] In this embodiment, the flexible electric heating films 3 are all connected to a temperature controller through wires. The temperature controller can control the increased temperature of the flexible electric heating films, increasing the adaptability.

[0029] During use, the webbing can be placed into the interior of the shaping channel along the opening on the outer side of the shaping channel, and the distance between the extrusion cylinders can be adjusted according to the width of the webbing. During adjustment, the screw can be directly rotated by the handwheel to move the screw inward along the screw hole. The movement of the screw drives the bracket and the extrusion cylinders. The middle part of the flexible electrothermal film can be made to move closer inward by the approaching extrusion cylinders and contact the upper and lower surfaces of the webbing. The webbing can be flattened up and down by the contacting flexible electrothermal film, and the friction acting on the webbing can make the webbing require a tensile force, that is, the so-called tension, during the passing process;

[0030] Among them, the flexible electrothermal film can generate heat by itself, and the generated heat can act inside the shaping channel. Once the webbing enters the shaping channel, it will be preheated, and it can be directly heated through direct contact with the webbing to ensure the sufficiency of heating and improve the shaping quality.

[0031] As described above, the above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any change or replacement that can be thought of without creative labor should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
