Uniaxial single spindle box of high-speed needling machine

Abstract

The invention discloses a uniaxial single spindle box of a high-speed needling machine, comprising a spindle box body, a spindle box cover, cam shafts, connecting rods, connecting rod pins, a push rod, guide sleeves, a balance block, a guide rod, a balancing weight, and the like, wherein the spindle box body and the spindle box cover are fixedly connected to form a whole body through screws, the cam shafts are fixed on the spindle box through a two-disc roller bearing and a spindle end cover, the large head ends of the two connecting rods are sleeved on the two cam shafts after being located by a snap spring through the roller bearing, the small head ends of the two connecting rods are respectively connected with the push rod and the guide rod to form a whole body through a two-disc bearing, and location of up and down movement of the push rod and the guide rod is finished by the two guide sleeves fixed on the spindle box body. Compared with the prior art, the single spindle box has the advantages of small volume and convenient installation and maintenance, perfects the functions of the traditional spindle box and can determine the configuration amount of the spindle box according to the stress condition of needle punched fabrics so as to reach the purpose of cost control and ensure that the performance price ratio of the needling machine is more reasonable.

Description

technical field [0001] The invention relates to a spindle box of an acupuncture machine, in particular to a single-shaft 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 type...

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
