A double-spindle transmission mechanism of a high-speed acupuncture machine

Abstract

A double-spindle transmission mechanism for a high-speed acupuncture machine, which relates to the structural field of an acupuncture machine, includes at least one set of camshafts arranged in pairs, and each camshaft is respectively provided with two bearing seats fixedly connected with a machine frame, each Bearing seats are respectively connected to the corresponding camshafts through the first bearings; eccentric wheels, connecting rods and counterweight wheels are respectively arranged on each camshaft, and each eccentric wheel, connecting rod and counterweight wheels are respectively arranged on the corresponding two Between the bearing housings, the upper end of each connecting rod is larger than the lower end, the big end of each connecting rod is connected to the corresponding eccentric wheel through the second roller bearing, and the small end of each connecting rod is respectively provided with a mounting hole; The transmission mechanism also includes a transfer case, the two output ends of the transfer case are respectively connected to the camshafts at the ends through the first coupling, and each camshaft is respectively arranged on the same side of the transfer case, and the two output ends of each group The direction of rotation of the root camshaft is opposite. The invention can bear the load of a high-speed acupuncture machine and has reasonable force distribution.

Description

technical field [0001] The invention relates to the structural field of acupuncture machines, in particular to a double-spindle transmission mechanism used in high-speed acupuncture machines. Background technique [0002] Needle punching nonwovens is the most common and extensive production method in the production process of nonwoven materials. Due to the characteristics of good permeability, excellent filtration performance and mechanical properties, needle-punched nonwovens are widely used in various industries such as geotechnical materials, filter materials, building waterproof materials, automotive interiors, synthetic leather substrates, and paper-making blankets. Non-woven fabric materials for daily use and daily use. Moreover, acupuncture nonwovens have many advantages such as simple processing technology, short process, flexible and convenient equipment combination, many types of products, wide application fields, less equipment investment, and short construction ...

AI Technical Summary

Problems solved by technology

The main problems of the spindle box transmission mechanism are as follows: 1) The friction between the push rod and the sliding sleeve is sliding friction, and the resistance is large; 2) The fixed distance between the two push rods is 600mm, which cannot reduce the friction of the push rod. 3) The center distance of the original connecting rod is too small; 4) There is oil leakage at the original push rod; 5) This headstock mechanism is limited by its own structure, which hinders acupuncture Further increase in frequency
