Description

Technical Field

[0001] The utility model relates to the technical field of epoxy glass fiber wound tube processing, in particular to a glue containing and defoaming device for epoxy glass fiber wound tubes. Background Art

[0002] Epoxy glass fiber wound insulation tube is a high-voltage electrical insulation material made of alkali-free untwisted glass fiber as reinforcement material. The glass fiber is passed through a yarn guide - combed - immersed in an epoxy resin tank - yarn separated - glue scraped - wound - heated and cured - demoulding, and then formed. It has high mechanical strength and excellent electrical properties and is widely used in the field of high-voltage electrical equipment.

[0003] Because existing epoxy resin tanks operate in an open environment, a large number of bubbles are trapped in the product during the dipping process, making it prone to delamination and cracking during the curing process. Even if delamination and cracking are avoided, the presence of a large number of microbubbles inside the product can significantly reduce its electrical performance, resulting in high partial discharge and certain inconveniences in use. Utility Model Content

[0004] The purpose of the utility model is to provide a glue containing and defoaming device for epoxy glass fiber wound tubes to solve the problems raised in the above background technology.

The output end of the motor is close to the outer wall of the motor, and the top of the base is fixedly connected to the support frame, and the support frame is rotatably connected to a two-way screw rod, one end of the two-way screw rod passes through the support frame and is fixedly connected to the second pulley, and the two-way screw rod is threadedly connected to the transmission block, and the bottom of the transmission block is fixedly connected to the hot air blower. The inner walls of both sides of the base are provided with limiting grooves, and the limiting blocks are slidably connected in the limiting grooves, and the opposite sides of the two limit blocks are fixedly connected with a glue storage bin, and the glue storage bin is provided with an extrusion groove on the side close to the motor, and the extrusion shaft is slidably connected to the extrusion groove.

[0006] Preferably, the diameter of the second pulley is greater than the diameter of the first pulley, and the first pulley is connected to the second pulley via a belt.

[0007] Preferably, a limiting shaft is fixedly connected to the middle position of the bottom end of the glue storage bin, and the limiting shaft is located at the bottom end of the epoxy resin glue liquid surface.

[0008] Preferably, the support frame is designed as a concave structure, and the transmission block is slidably connected to the bottom end of the support frame.

[0009] Preferably, the extrusion shaft and the extrusion groove are arranged correspondingly, and the extrusion shaft and the extrusion groove are slidably connected.

[0010] Compared with the existing technology, the beneficial effect of the utility model is that only the motor needs to be started to drive the glue storage bin storing the epoxy resin glue to vibrate slightly, and the original equilibrium state of the bubbles is changed by vibration. Since the density of the bubbles is much smaller than that of the epoxy resin, the bubbles tend to rise upward until they escape from the surface of the resin, and then the rising bubbles are blown apart by the reciprocating hot air blower, which can prevent the bubbles from being wrapped in the epoxy glass fiber wrapped insulation tube, optimize the production process, and improve the production and processing quality of the product.
