Single main spindle box of high-speed needling machine

Abstract

The invention discloses a single main spindle box of a high-speed needle machine, comprising parts of a main spindle box body, a main spindle box cover, cam spindles, two connecting rods, a cross girder, connecting rod pins, a push rod, a guide sleeve, and the like. The main spindle box body is fixedly connected with the main spindle box cover into a whole by bolts; the cam spindles are fixed on the main spindle box by two roller bearings and a main spindle end cover; big ends of the two connecting rods are positioned by a jump ring through the roller bearings and then are sleeved on the two cam spindles; the small ends of the two connecting rods are connected with the cross girder by the two bearings through the connecting rod pins; the cross girder is connected with the push rod by one connecting rod pin; and positioning of up-down movement of the push rod is completed by the guide sleeve fixed on the main spindle box body. Compared with the prior art, the single main spindle box has small volume and convenient installation and maintenance, improves functions of original main spindle boxes, can determine the configuration number of the main spindle box according to the force of needle-punched fabric so as to achieve the purpose of controlling cost, and ensure the cost performance of the needle machine to be more reasonable.

Description

technical field [0001] The invention relates to a spindle box of an acupuncture machine, in particular to a single spindle box of a high-speed acupuncture machine. 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. At present, the output of needle-punched nonwovens accounts for about a quarter of the total nonwovens. Moreover, acupuncture nonwovens have many advantages such as simple processing technology, short process, flexible and convenient equipment combination, many types of products...

AI Technical Summary

Problems solved by technology

The main problems of the original spindle box are as follows: 1) The volume of the spindle box is too large, which is inconvenient for processing, transportation, assembly, etc.; 2) The fixed distance between the two push rods cannot reduce the number of push rods , also limited by the size of the spindle box, the number of the spindle box cannot be reduced, which leads to the inability to reduce the cost of the acupuncture machine; 3) There are too many parts participating in the rotation in the spindle box, which increases the temperature of the lubricating oil, which is not conducive to lubrication Oil seal; 4) The original structure of the main shaft housing is unreasonable, which is not conducive to the cooling of the lubricating oil; 5) The split combination of the main shaft and the cam has a small error in secondary processing; 6) The bearing supporting the connecting rod The fulcrum is 1 on average, and the force is relatively uneven
