Spring loading device of pencil core combination machine for mechanical pencils

Abstract

The invention relates to a spring loading device of a pencil core combination machine for mechanical pencils, which comprises a vibrating disc, a conveying guide rail, a spring separately dischargingmechanism and a detection mechanism, wherein the conveying guide rail is provided with a conveying guide groove, and the spring separately discharging mechanism is arranged on the conveying guide rail. According to the technical scheme of the invention, the spring loading procedure can be completed quickly and accurately, other procedures are detected, the pencil core combination machine for the mechanical pencils is enabled to complete the combination and assembly of the pencil core efficiently and quickly, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of mechanical automation, in particular to a spring feeding device for a refill assembly machine of a mechanical pencil. Background technique [0002] Reference attached Figure 1-5 The refill 1 of the mechanical pencil is an important constituent mechanism of the mechanical pencil, including a lead storage tube 11, a spring 12, a spring seat cover 13 and a chuck 14 with a locking collar 15, and the lead storage tube 11 includes a body 111 , the first boss 112, the second boss 113, the bayonet 114, the spring seat cover 13 includes an inner end surface 131, an outer end surface 132, the chuck 14 includes an engaging end 142 and a claw piece 141, the refill 1 The combination is that the spring is sleeved on the second boss 113 so that one end of the spring 12 is against the upper end surface 1131 of the second boss 113, and the spring seat 13 is sleeved outside the spring 12 so that the other end of the spring 12 is in...

[0002] Reference attached Figure 1-5 The refill 1 of the mechanical pencil is an important constituent mechanism of the mechanical pencil, including a lead storage tube 11, a spring 12, a spring seat cover 13 and a chuck 14 with a locking collar 15, and the lead storage tube 11 includes a body 111 , the first boss 112, the second boss 113, the bayonet 114, the spring seat cover 13 includes an inner end surface 131, an outer end surface 132, the chuck 14 includes an engaging end 142 and a claw piece 141, the refill 1 The combination is that the spring is sleeved on the second boss 113 so that one end of the spring 12 is against the upper end surface 1131 of the second boss 113, and the spring seat 13 is sleeved outside the spring 12 so that the other end of the spring 12 is in contact with the spring seat. The inner end surface 131 of the cover 13 is offset, and the engaging end 142 of the chuck 14 with the locking band 15 passes through the spring seat cover 13 and the spring and the bayonet 114 of the lead storage pipe 11 is snapped together, so that the locking band 15 and the lead storage tube 11 are engaged. The outer end surface 132 of the spring seat cover 13 offsets each other. At present, the combination of the mechanical pencil lead is manually performed, which is low in efficiency and high in cost.
