Abstract
The utility model discloses an inflatable shaft for effective rolling of ethylene/vinyl acetate (EVA) films. The inflatable shaft for the effective rolling of the EVA films comprises a shaft body (1), shaft heads (2) are arranged at two ends of the shaft body (1), and an inner air container (3) is arranged in the shaft body (1). The surface of the shaft body (1) is provided with a bar groove (4) which is communicated with the inner air container (3), and an expansion strip (5) is disposed in the bar groove (4). An air-filled air tap is arranged at one end of the shaft body. The inflatable shaft for the effective rolling of the EVA films fits closely with a film shaft sleeve when rotating, effectively drives the film shaft sleeve to rotate and to roll the EVA films, avoids wrinkling and damage of the EVA films due to slipping of the film shaft sleeve and a rolling shaft, and improves service performance of the EVA film.
Description
Technical field
The utility model relates to the inflatable axle that a kind of effective rolling EVA glued membrane is used, and belongs to EVA glued membrane production facilities field.
Background technology
Solar power encapsulating film equipment is to be used for making being used in the EVA glued membrane that packaged battery is used on the solar panel (also being the solar power glued membrane); Its light transmittance of EVA glued membrane of using this device fabrication is than higher; Rational degree of crosslinking is arranged, stronger adhesive property is arranged, the function of remarkable UV resistant is arranged; Extremely low shrinkage percentage, this EVA glued membrane can improve solar panel is converted into electric energy with luminous energy efficient.The general employing of EVA glued membrane extruded-production of hydrostomia method.Production process comprises melt blending, extrudes, cotton ginning, traction, rolling etc., and wherein winding process is realized in rolling-up mechanism.
At present, the main equipment of rolling-up mechanism promptly is the Scroll that the rolling glued membrane is used, and the workman is enclosed within the glued membrane axle sleeve on the Scroll before the rolling, and the rotation through Scroll drives the glued membrane axle sleeve and carries out the rolling glued membrane, and rolling finishes and takes off the glued membrane axle sleeve.The fit system of existing Scroll and glued membrane axle sleeve is a screw thread fit; Be round table-like fixedly spindle nose promptly in the end of Scroll; And offer screw thread on the spindle nose; The workman is enclosed within glued membrane axle sleeves such as made of paper or plastics system on the Scroll during use, and rotates inwards, makes glued membrane axle sleeve and Scroll realize screw thread fit closely; Yet the mode that existing glued membrane axle sleeve cooperates with Scroll mainly contains following problem: 1, and the situation that the glued membrane axle sleeve damages appears in workman easily when rotating glued membrane axle sleeve such as made of paper or plastics system; 2, to rotate the glued membrane axle sleeve and make it enough closely to need the more time of cost with Scroll, efficient is comparatively low; 3, the effect of screw thread fit is also unsatisfactory, occurs the situation that the Scroll rotation causes and the glued membrane axle sleeve is loosening easily.
The utility model content
The purpose of the utility model is, the inflatable axle that provides a kind of effective rolling EVA glued membrane to use.The utility model is in rotation process; Cooperate closely with the glued membrane axle sleeve; Drive effectively that the glued membrane axle sleeve rotates and rolling EVA glued membrane, avoided causing the EVA glued membrane fold even damaged situation to occur because of glued membrane axle sleeve and Scroll skid, result of use is very desirable; Simultaneously, the utility model can protect the glued membrane axle sleeve to be without prejudice effectively, and the button that work the time only needs the workman to click air pump can be realized high efficiency.
The technical scheme of the utility model: the inflatable axle that a kind of effective rolling EVA glued membrane is used, comprise axis body, the two ends of axis body are spindle nose, and the inside of axis body has a gas courage, and the surface of axis body offers bar-shaped trough, and bar-shaped trough is communicated with the gas courage, is provided with bloated bar in the bar-shaped trough; One end of axis body also is provided with gas filed valve.
Preferably, in the inflatable axle that above-mentioned effective rolling EVA glued membrane is used, the surface of described axis body also is provided with measuring scale.
Compared with prior art; The utility model adopts the inflatable axle with the Scroll of using in the rolling-up mechanism, and to the physical property of EVA glued membrane the inflatable axle is improved, and the axis body inside of inflatable axle has a gas courage; The gas courage is communicated with bar-shaped trough, is provided with bloated bar in the bar-shaped trough; During the ventilation of gas courage; Air pressure drives the bar that expands and pushes up outside axis body from bar-shaped trough; And cooperate closely with outside glued membrane axle sleeve of cover; Therefore the utility model can drive the glued membrane axle sleeve effectively and rotate rolling EVA glued membrane, has avoided causing the EVA glued membrane situation of fold even breakage to occur because of glued membrane axle sleeve and Scroll skid, and has improved the in-use performance of EVA glued membrane.As preferably, the surface of axis body also is provided with measuring scale, makes things convenient for the accurate cutting of glued membrane.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the section drawing of the utility model.
Being labeled as in the accompanying drawing: 1-axis body, 2-spindle nose, 3-gas courage, 4-bar-shaped trough, the 5-bar that expands, 6-measuring scale, 7-valve.
The specific embodiment
Below in conjunction with embodiment the utility model is done further to specify, but not as the restriction to the utility model.
The embodiment of the utility model.The inflatable axle that effective rolling EVA glued membrane is used also is Scroll, as attaches illustrated in figures 1 and 2; Comprise axis body 1, the two ends of axis body 1 are spindle nose 2, and the inside of axis body 1 has a gas courage 3; The surface of axis body 1 offers bar-shaped trough 4, and bar-shaped trough 4 is communicated with gas courage 3, is provided with the bar 5 that expands in the bar-shaped trough 4; One end of axis body 1 also is provided with the valve 7 of inflation usefulness, and inflation pump links to each other with valve through pipeline during work, and an electromagnetic valve is set on pipeline, presses the work that button is realized the inflatable axle through the workman; The surface of described axis body 1 also is provided with measuring scale 6.During the ventilation of gas courage; Air pressure drives the bar that expands and pushes up outside axis body from bar-shaped trough; And cooperate closely with outside glued membrane axle sleeve of cover; Therefore the utility model can drive the glued membrane axle sleeve effectively and rotate rolling EVA glued membrane, has avoided causing the EVA glued membrane situation of fold even breakage to occur because of glued membrane axle sleeve and Scroll skid, and has improved the in-use performance of EVA glued membrane.
