Description

Technical Field

[0001] The utility model belongs to the technical field of acrylic plate production equipment, and particularly relates to a device for hardening acrylic plates. Background Art

[0002] Existing acrylic sheet hardening devices have some significant shortcomings in cycle drying. First, uneven temperature distribution is a common problem, which may lead to uneven hardening of acrylic sheets and affect product quality. This defect is usually caused by unreasonable internal structural design of the drying device or uneven arrangement of heating elements. Secondly, the humidity control during the cycle drying process is not accurate, which can easily lead to bubbles or cracks on the surface of the acrylic sheet, which is mainly due to the insufficient sensitivity of the humidity sensor or the imperfect feedback mechanism of the control system. In addition, the drying speed is slow, which affects production efficiency, which may be caused by insufficient power of the heating system or inefficient circulation system.

[0003] Conventional countermeasures include improving the layout of heating elements to improve the uniformity of temperature distribution; using higher-precision humidity sensors and more advanced control algorithms to optimize humidity control; and increasing the power of the heating system and the efficiency of the circulation system to speed up drying. However, these methods themselves also have some disadvantages. Improving the layout of heating elements requires redesigning and manufacturing the internal structure of the equipment, which may lead to increased costs; using higher-precision humidity sensors and advanced control algorithms requires additional R&D resources and technical support, which increases the complexity of the equipment and the difficulty of maintenance; increasing the power of the heating system and the efficiency of the circulation system may increase energy consumption, leading to increased operating costs. Therefore, we hope to design an acrylic plate hardening device with a new structure to solve this problem. Utility Model Content
