Description

A rubber sleeve assembly quality for ballpoint production

Technical Field

The invention relates to the field of ball pen processing, in particular to a rubber sleeve assembling device for ball pen production.

Background

Ball-point pens are pens in which the writing medium is carried out by rolling a ball at the front end of the pen or refill. At present, a plurality of ball-point pens are provided with rubber sleeves which can increase friction force, fingers can be pinched tightly during writing, the ball-point pens are not easy to slip, and harder plastics can be prevented from hurting hands. The rubber leather sheath is arranged at pen point positions of a ball pen, a gel ink pen and the like, all parts are formed by manual assembly after mechanical batch production, when the rubber leather sheath is sleeved, the fingers are required to be pressed to push in, the fingers are easily abraded for a long time, and the work efficiency is low. Patent CN203292794U proposes a ball-point pen rubber sleeve pressing device, which includes a machine body 4, a bracket 31, a rotary table 10, a pressing cap 19 and a jaw 30, wherein a motor 13 and a speed reducer 14 are arranged at the lower part of the machine body 4; a transmission shaft 29 is arranged on the speed reducer 14; the transmission shaft 29 is provided with a cam 28 and a transmission gear 17; the cam 28 is meshed with the turntable gear 18 on the turntable transmission shaft 12; the turntable 10 is arranged at the upper end of the turntable transmission shaft 12, and positioning pins 9 are arranged on the periphery of the turntable 10; the transmission gear 17 is meshed with a vertical shaft gear 29 arranged on a vertical shaft 3, a lower bevel gear 5 and an upper bevel gear 2 are arranged on the vertical shaft 3, and the lower bevel gear 5 is meshed with a jaw shaft gear 6 arranged on a jaw connecting shaft 8. Although the technical problems that the fingers are easily abraded and the working efficiency is low are solved. But still need the staff to overlap the rubber sleeve on the pen-holder head, insert the pen-holder on the locating pin again, the device still need take off the pen-holder after pressing into the rubber sleeve, and degree of automation is low, and efficiency still is not high enough, and it neglects the spacing ring on the cover groove of pen-holder moreover, and the rubber sleeve can be blockked by the spacing ring when pressing into the rubber sleeve.
