AI Technical Summary
Technical Problem
In existing technologies, waste blocks made from PVB film production waste pressed at room temperature are prone to springing back and becoming loose, requiring additional bundling, which increases the process and cost.
Method used
The PVB film waste is heated by heating elements to soften it slightly. Then, it is pressed together by a stirring plate and a pressure plate. Taking advantage of the thermoplasticity of PVB material, the waste is bonded together and uniformly stirred by the stirring plate during the heating process.
Benefits of technology
It effectively solves the problem of loose and springy waste blocks, forming dense waste blocks with strong bonding force, eliminating the need for additional binding, simplifying the processing procedures and reducing costs.

Abstract
The invention provides a waste treatment device and method for PVB film production. The waste treatment device comprises an operation cavity, a heating element, a pressing plate and a stirring assembly. The operation cavity is used for containing PVB film waste, and an inlet-outlet is formed in the top of the operation cavity. The heating element is used for heating the PVB film waste in the operation cavity; the pressing plate is arranged above the inlet and outlet and can be driven by the first driving device to move in a reciprocating mode in the vertical direction. An avoiding opening is formed in the pressing plate; the stirring assembly comprises a second driving device, a stirring driving device and a stirring plate; and the second driving device is arranged on the pressing plate and is used for driving the stirring driving device to reciprocate along the vertical direction. The PVB film waste materials are heated through the heating element, so that the PVB film waste materials are pressed in a slightly softened state, and the PVB film waste materials are mutually bonded by utilizing thermoplasticity of the PVB materials, so that the technical problems that waste material blocks obtained through normal-temperature pressing are easy to rebound and loosen and need to be additionally bundled are effectively solved.
