Mini magnetic damping control device and cushioning air cushion machine

Abstract

The invention discloses a miniature magnetic damping control device and a cushion air cushion machine, which include two butted semi-cylindrical shells and a magnetic damping control assembly, wherein: the magnetic damping control assembly specifically includes a rotating shaft and a bottom-up A base, an aluminum base, a first bearing, a first annular magnet block, a hysteresis sheet, an aluminum ring, a second annular magnet block, a second bearing, and a rotating head are sleeved on the rotating shaft. The miniature magnetic damping control device and the buffer air cushion machine provided by the present invention utilize the magnetic damping effect to realize the resistance to the rotation of the rotating shaft through magnetic force without contact, and realize the constant resistance of the rotating shaft rotation. It obviously overcomes the technical defects of the traditional friction damping device, thereby improving the service life of parts and the whole machine, and ensuring stable operation.

Description

Technical field [0001] The invention relates to the technical field of packaging equipment, in particular to a mini-type magnetic damping control device and a cushion air cushion machine. Background technique [0002] In daily life, in order to prevent the transported goods from being broken during transportation, the usual method is to use cushioning air cushion film for cushion packaging, which can ensure the transport safety of the transported goods and ensure that the packaging is beautiful and atmospheric. [0003] Our company designed a product in the research process of the film tension of the film inflatable packaging equipment on the product quality; it adopts a new structural design, and at the same time overcomes the problem of unstable tension of the film, thereby overcoming the traditional In the technology, the abnormal change of the film tension causes the problem of poor heat sealing during heat sealing (that is, the film will produce wrinkles during heat sealing, t...

AI Technical Summary

Problems solved by technology

[0007] However, after research, it is found that the above-mentioned film air packaging equipment has certain technical defects; for example, during the operation of the equipment, the ring magnet block 22 will come into contact with the fixed shaft 24 underneath, which will cause wear and tear, which will affect the normal use of the equipment.

Especially under long-term work, the bottom surface of the magnet and the fixed shaft will wear more seriously, thereby reducing the service life of the equipment
