Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper production, in particular to a corrugated paperboard production speed measuring mechanism. Background Art

[0002] Corrugated cardboard is a multi-layer adhesive body, which is composed of at least a layer of wavy core paper interlayer and a layer of cardboard on both sides. The corrugated corrugations of the corrugated cardboard are like connected arched doors, arranged in a row and supporting each other to form a triangular structure. It has high mechanical strength and can withstand collisions and falls during transportation. Therefore, the compressive strength of the corrugated cardboard needs to be tested after production to ensure that the compressive strength of the corrugated cardboard meets the requirements for use.

[0003] There are two types of speed measuring devices commonly used in the market: the first type is the traditional contact-type speed measuring roller structure. This speed measuring roller structure is usually a long roller structure that is pneumatically lifted and lowered. When working, the entire speed measuring roller is directly pressed against the surface of the cardboard through the cylinder, and the friction between the cardboard and the roller surface drives the roller body to rotate, and then cooperates with the encoder to achieve the purpose of real-time detection of the cardboard speed. This structure has a low price, but due to the large length of the speed measuring roller itself, the inertia of the speed measuring roller is large. In order to prevent the speed measuring wheel and the cardboard from slipping during the production process, the downward pressure of the speed measuring roller must be large enough. The consequence of this is that when the cardboard is low in weight and the cardboard is soft, the speed measuring roller will leave an indentation on the surface of the cardboard, resulting in reduced cardboard quality and affecting customer delivery. The second type is the non-contact laser speed meter that has gradually been used in corrugated lines in recent years.

[0004] When the existing laser speed meter is in use, its moving track and the speed meter are fixed by bolt connection during installation, so that when the speed meter is inspected and maintained, it is necessary to unscrew the bolts one by one to disassemble it, which leads to slow progress of the speed meter inspection and maintenance work, thereby affecting the subsequent use of the speed meter. Therefore, a corrugated cardboard production speed measuring mechanism is proposed to solve the above problem. Utility Model Content
