Technical Field
[0001] The utility model relates to the technical field of calenders, in particular to a pressurizing and decompressing mechanism of a calender. Background Art
[0002] A glass calender is an important device specifically used for glass production and processing. It usually consists of calender rolls, a heating system, a transmission device, etc. Through the extrusion and extension of high-temperature glass liquid by the calender rolls, a glass plate with a specific thickness and surface quality is formed. During operation, precise temperature control and pressure regulation are crucial. For example, when producing photovoltaic glass, the glass calender can manufacture ultra-thin glass that meets the requirements; in the production of architectural glass, decorative glass with good aesthetics and performance can be calendered. The continuous innovation and optimization of the glass calender have improved the quality and production efficiency of glass products and promoted the development of the glass industry.
[0003] The prior art such as the utility model with the publication number of CN204939255U discloses a pressure automatic adjustment device for a thin glass calender. This patent uses a pressure sensor, so that the pressure value can be sensed by the pressure sensor and fed back to make the motor lift perform automatic pressurization or decompression pressure adjustment; according to the pressure automatic adjustment device of the thin glass calender of the present utility model, the spring device can store energy and then release it. By pushing the expansion and contraction of the pressure rod through the lever bracket, the pressure can be loaded and unloaded slowly, so that the output pressure of the lift will not be rigidly loaded on the calender roll. Another advantage is that this device is equipped with a pressure automatic adjustment system, which constantly tracks and feedbacks the pressure value and continuously corrects the pressure value, thus ensuring the stability of the pressure value received by the calender roll and solving the problem that when the glass belt passes through the calender roll in the existing equipment, a certain tension is formed on the glass surface and acts on the upper calender roll, causing the upper calender roll to have a tendency to jump, and the thickness difference of the glass will be uneven.
[0004] In the process of adjusting the pressure of the pressure roller by means of a pressurizing and decompressing mechanism, there are most automated pressure mechanisms on the existing market. When in use, a pressing plate is used to connect the pressure part of the equipment and the pressure roller, so that the equipment can only press the pressure roller during the downward pressing process and it is difficult to lift the pressure roller for decompression. When the pressure roller loses pressure, it can only rely on the acting force of the material itself to lift the pressure roller upward, resulting in the unstable position of the pressure roller, and it will jump during operation, causing the thickness of the material processed by the equipment to be uneven.

[0010] Preferably, the number of the buckle frames is two, and the two buckle frames are vertically distributed with respect to the pressure rod. The pressure rod and the reinforcement frame can be connected through the buckle frames, thereby achieving a reinforcement effect on the assembly plate.
