Ballpoint pen and gel pen nib and pen barrel automatic separation device

Abstract

The invention relates to an automatic separation device for metals and plastics, in particular to an automatic separation device for pen points and pen holders of ball pens and gel pens. The automatic separation device comprises a refill positioning mechanism and a pen point extracting mechanism, wherein the pen point extracting mechanism comprises a planar cam link transmission mechanism and a pen point clamping mechanism; the planar cam connecting rod transmission mechanism comprises an eccentric driving wheel connected with a power mechanism, and a connecting rod which is in transmission connection with the eccentric driving wheel and performs reciprocating linear motion along a guide rail fixed on a frame tabletop; a movable claw and a fixed claw of the pen point clamping mechanism are arranged below a fixed claw at the front end of the connecting rod in a matched hinging mode; the connecting rod is provided with a driven eccentric wheel in matched hinge with a torque rod of the movable claw; a poking rod is connected to the driven eccentric wheel; and two fixing posts matched with the poking rod are arranged on the frame tabletop. The automatic separation device is simple in structure and reasonable in design, automatically separates and sorts the pen points and the pen holders of the ball pens and the gel pens, and contributes to saving resources and protecting environment.

Description

technical field [0001] The invention relates to an automatic separation device for metal and plastic, in particular to an automatic separation device for the tip and the holder of a ballpoint pen and gel pen. Background technique [0002] At present, the main manufacturing materials of gel pens or ballpoint pen barrels are polystyrene or modified polystyrene. These two materials have the characteristics of corrosion resistance and aging resistance. . In addition, the pen core also contains pollutants such as volatile excess floating fat. The residual substances in the unused gel pen core, including ink, floating grease and other pollutants, if discarded at will after use, will cause certain pollution to the soil and water quality. [0003] According to relevant reports, gel pens and refills that are discarded in large quantities are very likely to become another new killer of the environment after white garbage and waste batteries. If it is not recycled, it will easily ca...

AI Technical Summary

Problems solved by technology

[0004] However, since the gel pen is composed of two parts, the nib and the pen holder, for the recycling of the gel pen, if the problem of separation of the plastic pen holder and the metal nib is not solved, it will inevitably cause waste of resources

At present, there is no relatively mature product or technology on the market that separates the metal nib from the plastic pen holder.
