Description

Film guide apparatus for manufacturing spiral laminate insulation tube TECHNICAL FIELD

The present invention relates to a film guide device for manufacturing a spiral laminate insulating tube, and more particularly, to determine the entry angle and the interval of a plurality of insulating films supplied to a forming tube for forming by continuously winding a plurality of insulating films in a spiral shape. It relates to an apparatus for manufacturing a spiral laminate insulating tube that can be precisely controlled.

In general, insulation or chemical resistance or tube is used for the protection of wires or electrical connection parts, including various electromagnetic products throughout the industry for transmitting power or communication signals, for example, protection of wires for high voltage power transport, Protection of media for power supply and communication or signal transmission of electronic equipment and various industrial electric products, protection of the welding part of the electric motor coil and lead wire inside the compressor constituting the refrigeration cycle device, various electric vehicles equipped with lithium-ion batteries It can be used to protect electronic equipment.

These tubes use a variety of synthetic resins including PVC, silicone, Teflon, and polyolefins to supply raw materials to an extrusion molding machine and push them out of the extrusion mold to form a continuous body with a uniform cross-section, and yarns of various materials. It is broadly classified into a braided molding method, which is braided into a mesh form using a mesh, and a spiral laminate method formed into a hollow tubular shape by laminating several layers of insulating films. Among these methods, insulation, heat resistance, cold resistance, oil resistance, chemical resistance, and durability are classified. Tubes manufactured in a spiral lamination method are used for wires, conduits, or connecting parts of various electronic devices that require the same.

Meanwhile, in the spiral laminate tube, an insulating film made of polyvinyl chloride, polyester, epoxy resin, polyamide film, Teflon film, etc., which have a strip shape with excellent heat resistance, insulation, and chemical resistance, etc. It is formed by winding into a spiral shape through friction and roll pressing.

As a conventional technology for automatically manufacturing an insulating tube through roll friction and roll pressure as described above, the'automatic insulating tube manufacturing device' of the Korean Utility Model Registration No. 20-0248533 previously applied and registered by the present applicant has been proposed. In 1,'In an apparatus for manufacturing a tubular tube by winding a plurality of insulating films coated with an adhesive by friction of a belt: (1) The rotational power generated by the driving motor is axially arranged and combined in the molding frame. Power conversion means for decelerating and converting clockwise and counterclockwise to transmit; (2) a first, each of which one end is coupled to the power conversion means and the other end is penetrated to the upper portion of the molding frame, and is positioned to be inclined to each other at a predetermined angle from the penetration, and rotates clockwise and counterclockwise, respectively. A second crankshaft; (3) first and second brackets axially penetrating and coupled to the first and second crankshafts to support the first and second crankshafts; (4) The ends of the first and second crankshafts are axially coupled to each other at regular intervals, rotate in one direction by the transmitted rotational power, and apply friction and pressure to the supplied plurality of films.

The conventional tube automatic manufacturing apparatus previously filed by the present applicant according to the prior art is provided with two friction rollers capable of adjusting the inclination angle and spacing with respect to the axis of the upper surface of the forming frame, so that the insulating film can be applied to roll friction and roll pressing. Although a configuration for manufacturing an insulating tube by winding it in a spiral through the method is disclosed, in this configuration, as the inclination angle of the two friction rollers is increased, the overlapping degree and the twist angle for uniformly overlapping the insulating films are improved. As the contact area of the insulating film decreases, the tension of the insulating film decreases so that it is wound loosely. Conversely, the smaller the inclination angle of the two friction rollers, the larger the contact area with the insulating film, which increases the tension of the insulating film. On the other hand, there was a problem in that the incidence of defects was increased due to the decrease in the overlapping degree and the twisting angle.

As another prior art, the'automatic insulating tube manufacturing apparatus' of Korean Patent Publication No. 10-0830644, which was previously applied and registered by the present applicant, has been proposed, and the claim 1 discloses'three pulleys in the drive motor pulley in the molding frame. Is coupled to the shaft at regular intervals by means of a timing belt to reduce the rotational power in one direction clockwise and counterclockwise, and due to the rotational direction converted from the deceleration, an adhesive is applied to insulate a plurality of sheets placed on the forming rod. In the apparatus for producing a tubular tube by imparting tension and rotational friction to a film;

(1) Horizontally fixed to the left and right inner walls of the center of the molding frame, and at a predetermined position, the arc-shaped first and second inner long holes and the arc-shaped first and second outer long holes having the same length are spaced apart from each other. A horizontal frame formed in the same line; (2) One end is vertically coupled to the central axis of the two pulleys rotating in opposite directions at a predetermined interval, and the other end is penetrated through the first and second inner long holes of the horizontal frame to rotate at reduced speed. 2 crankshaft; (3) upper and lower belt driving means that are horizontally coupled in a state spaced apart from the upper surface of the horizontal frame and convert the upper and lower belts into horizontal linear motion according to the rotational motion of the first and second crankshafts; (4) The upper and lower belts caused by the upper and lower belt driving means are moved along the first and second inner long holes and the first and second outer long holes of the horizontal frame to enable proximity and distance from each other. Upper and lower cross angle adjustment means for adjusting the cross angle of one end of the; And (5) the upper cross angle adjusting means and the upper belt driving means are coupled to the upper belt driving means by raising and lowering the other side based on one axis of the upper belt driving means to adjust the spacing of one end of the upper and lower belts. Insulation tube automatic manufacturing apparatus, characterized in that it comprises a tension control means for maintaining the tension of the insulating films.' is disclosed.

However, the apparatus for manufacturing an insulating tube proposed by the present applicant has a disadvantage due to the disadvantage that it is difficult to precisely control the overlapping degree and the overlapping angle according to various diameter standards or the number of layers of insulating film.
