Description

Technical Field

[0001] The utility model belongs to the technical field of rubber roller measuring devices, in particular to a rubber roller contact pressure measuring device. Background Art

[0002] Rubber rollers are a key equipment component widely used in many industrial fields such as printing, coating, papermaking, plastics, textiles, leather, wood processing, metal calendering, food packaging, etc. The production of rubber rollers involves multiple processes, among which the relevant quality inspections are required after the main parts of the rubber rollers are produced. Among them, the contact pressure measurement of the rubber rollers is one of the inspection links. There are many ways to measure the contact pressure of rubber rollers, and different measurement methods will be used according to different production conditions and quality inspection requirements. However, the common measuring devices for the contact pressure of rubber rollers have a fixed structure for fixing the rubber roller body, and thus cannot be used for the inspection of rubber rollers of various sizes and specifications. In actual related production, the specifications of the rubber rollers produced by an enterprise are diverse, which makes the use of the measuring device relatively narrow. In actual quality inspections, the enterprise may not conduct a full series of inspections due to equipment limitations, resulting in lax quality control and prone to quality accidents.
