Leather drying device capable of automatically relieving pressure

Abstract

The invention relates to a leather drying device capable of automatically relieving pressure, which comprises a main body, a pressure relief mechanism and a sealing mechanism; the pressure relief mechanism is arranged on the main body; the sealing mechanism is arranged on the pressure relief mechanism; the pressure relief mechanism comprises an exhaust pipe and a pressure relief assembly; the sealing mechanism comprises a sealing assembly and an air blowing assembly; a piston of a piston rod is provided with a sealing assembly; and the sealing assembly comprises a sealing ring and a push unit. According to the leather drying device capable of automatically relieving pressure provided by the invention, the main body is subjected to pressure relief through the pressure relief mechanism, the pressure relief mechanism is sealed through the sealing mechanism, so that heat leakage is avoided, the better drying effect is achieved, the pressure relief mechanism is of a pure mechanical structure, the stability of the device is improved, and the service life of the device is prolonged; multiple sealing is conducted on the pressure relief mechanism through the sealing assembly and the air blowing assembly, the better sealing effect is achieved, a gap between the piston rod and a sleeve is sealed through the sealing assembly and a positioning unit, and the service life of the air blowing assembly is prolonged.

Description

technical field [0001] The invention relates to a leather drying device capable of automatic pressure relief. Background technique [0002] Leather is denatured and non-perishable animal skin obtained through physical and chemical processing of depilation and tanning. Leather is composed of natural protein fibers tightly woven in three-dimensional space. Its surface has a special grain layer with natural grain patterns. And luster, feel comfortable, including household leather, national defense leather, industrial and agricultural leather, cultural and sporting goods leather, etc. [0003] When leather is produced and processed, it is usually necessary to dry the leather first. When the existing drying device is in use, the pressure in the device is generally detected through a pressure gauge, and then the solenoid valve is controlled by PLC to release the pressure. Electronic components such as solenoid valves have insufficient stability and low service life. At the same t...

Problems solved by technology

[0003] When leather is produced and processed, it is usually necessary to dry the leather first. When the existing drying device is in use, the pressure in the device is generally detected through a pressure gauge, and then the solenoid valve is controlled by PLC to release the pressure. Electronic components such as solenoid valves have insufficient stability and low service life. At the same time, the existing devices that use mechanical methods for pressure control have general sealing performance, and the heat in the device may leak through the gaps in the connection, affecting drying.
