Ventilation system for thermal bonding of large-size plexiglass balls

Abstract

The invention discloses a ventilation system for thermal bonding of large-size plexiglass balls, and relates to the field of instruments for thermal bonding of plexiglass balls. The ventilation systemfor thermal bonding of the large-size plexiglass balls comprises an annular air pipe, a middle communicating pipe, an exhaust fan and a supporting assembly. The annular air pipe is provided with a plurality of air holes communicating with the inside of the annular air pipe in the circumferential direction; one end of the middle communicating pipe communicates with the annular air pipe; the exhaust fan communicates with one end, far away from the annular air pipe, of the middle communication pipe; and the supporting assembly comprises a plurality of supporting devices and a plurality of locking devices, the supporting devices are uniformly arranged in the circumferential direction of the annular air pipe, one end of each supporting device is connected with the annular air pipe, the other end of each supporting device is slidably arranged on the side wall of a factory building, the sliding direction of each supporting device is in the height direction of the factory building, the supporting devices correspond to the locking devices one by one, and each locking device is used for locking the corresponding supporting device on the side wall of the factory building. The ventilation system can accurately control the ambient temperature within the requirement range of the thermal bonding process of the plexiglass balls.

Description

technical field [0001] The invention relates to the field of equipment for thermal bonding of plexiglass balls, in particular to a ventilation system for thermal bonding of large-sized plexiglass balls. Background technique [0002] Large-sized plexiglass balls are often formed by thermally bonding several plexiglass plates layered along the latitude direction by bulk polymerization, and the process emits a lot of heat. Since plexiglass is a poor conductor of heat, sharp temperature changes will cause many problems such as self-acceleration and implosion, as well as volume shrinkage and bubbles, which will affect the mechanical strength of the product. In order to dissipate heat, a ventilation system is often used in the thermal bonding process of large-sized plexiglass spheres. At present, for the thermal bonding process of large-sized plexiglass balls, the ventilation system used in industry is fixed on the upper part of the factory building, the cold air is sent in from ...
