Description

Automatic change rubber tube former

Technical Field

The utility model relates to the technical field of mechanical equipment, in particular to rubber tube forming exhaust equipment.

Background

Rubber tubes are usually used in connecting pipelines of products such as automobiles, air conditioners and the like, the rubber tubes on the market at present are generally multi-layer rubber tubes, the rubber tubes are formed by winding a plurality of layers of different materials, such as silica gel sheets, two or more silica gel sheets are stacked, and because a plurality of air holes or air cavities exist between the silica gel sheets, air in the air holes or the air cavities is required to be extruded. The traditional method is generally to roll the laminated silica gel sheets from the two rollers by manual operation through the upper roller and the lower roller, and extrude air in the air holes or the air cavity, but the exhaust effect of the mode is often not ideal. Therefore, for example, the patent named as 'rubber tube forming exhaust equipment' realizes clamping and rotating the positioning rod wrapped by each material layer for the rubber tube through the main shaft clamping mechanism and the rear positioning mechanism which are oppositely arranged, and meanwhile, the adhesive tape cloth belt feeding mechanism which can slide between the main shaft clamping mechanism and the rear positioning mechanism is arranged on the same side of the main shaft clamping mechanism and the rear positioning mechanism, and cloth belts can be fed out through the adhesive tape cloth belt feeding mechanism and wound outside the material layers after one layer of material layer is wrapped, so that two adjacent layers of material layers are laminated and air is exhausted, and the exhaust effect is improved.

However, the above-described apparatus has some problems such as: the cloth belt and the rotary shaft of the adhesive tape are arranged to move relative to the main shaft so as to adjust the tension by adjusting the rotation speed difference between the two shafts, but the tension is unstable and the experience requirement of the machine adjusting personnel is high. In addition, when the equipment is operated, an operator needs to wrap materials manually and operate the equipment by hand, so that the operation is inconvenient, the operator feels that the hand is not enough, and dirt on the materials is easily stuck to an operation panel, so that the operation is insensitive. Moreover, at present, a center (thimble) is manually dragged to tightly push or loosen a mandrel (a mould core/a main shaft) for working or discharging, and the operation is time-consuming and labor-consuming. In addition, the tape needs to be reused, and therefore needs to be recovered after winding is completed. Traditional equipment can not report wrong when the winding goes wrong, can damage the strap. Meanwhile, as the cloth belt wheel and the rubber belt wheel are provided with the driving and controlling mechanisms with larger sizes, a pipe cutting mechanism is not arranged in space, and only the formed die blank can be taken out for cutting in the next link, so that the production efficiency is reduced, and the cost is increased.
