Description
Technical field
The present invention relates to a kind of cam production chopper device, specifically by the device that cam production chopper pumps, belong to printing equipment technical field.
Background technology
At present, folding work has been carried out in a pile folding roller that 16 K folder of printer part utilizes chopper device printed sheet press-in relatively to be rotated.
Traditional chopper device generally adopts piston crank mechanism or planetary wheeling mechanism to control pumping of chopper, and its shortcoming is that the impulsive force of chopper is large, and reciprocating travel is long, and work efficiency is lower.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thus a kind of cam production chopper device be provided, pumped by cam production chopper, impulsive force and acceleration/accel less, reciprocating travel is short.
According to technical scheme provided by the invention, cam production chopper device comprises the chopper frame be connected in chopper rotating shaft and the cam being connected to camshaft left end, it is characterized in that: chopper frame front end connects grip block, grip block connects pressing plate, clamps chopper between grip block and pressing plate; Chopper frame is bolted grip block, and grip block lower end connects worm-wheel shaft, and worm-wheel shaft installs turbine, and upper cam surface contacts with turbine lower surface; Be provided with torsion bar spring in chopper rotating shaft, torsion bar spring left end connects left shaft holder, and left shaft holder connects chopper rotating shaft by needle bearing; Left shaft holder side is bolted permanent seat, is provided with torsion bar spring seat between permanent seat and torsion bar spring; Chopper rotating shaft right-hand member connects right bearing seat by combination bearing.
Further, by bearing, Cam bearing pedestal is installed in the middle part of camshaft.
Further, camshaft right-hand member connects gear by flat key.
Further, left shaft holder connects the first oil nozzle.
Further, right bearing seat is provided with the second oil nozzle.
Further, chopper rotating shaft connects spacing panel seat, spacing panel seat fixes positioning plate.
Compared with the prior art the present invention has the following advantages:
Structure of the present invention is simple, compact, reasonable, is pumped by cam production chopper, impulsive force and acceleration/accel less, reciprocating travel is short.

Detailed description of the invention
Embodiment in is by reference to the accompanying drawings further described by the present invention below:
As shown in Figure 1 and 2, the present invention mainly comprises the chopper frame 2 be connected in chopper rotating shaft 1, and chopper frame 2 front end connects grip block 22, grip block 22 connects pressing plate 23, clamps chopper 34 between grip block 22 and pressing plate 23.
Chopper frame 2 is bolted grip block 9, grip block 9 lower end connects worm-wheel shaft 15, worm-wheel shaft 15 is installed turbine 16.
The present invention also comprises the cam 17 being connected to camshaft 19 left end, and cam 17 upper surface contacts with turbine 16 lower surface.Install Cam bearing pedestal 21 by bearing 20 in the middle part of camshaft 19, camshaft 19 right-hand member connects gear 18 by flat key.
Be provided with torsion bar spring 8 in chopper rotating shaft 1, torsion bar spring 8 left end connects left shaft holder 5, and left shaft holder 5 connects chopper rotating shaft 1 by needle bearing 7.Left shaft holder 5 side is bolted permanent seat 3, is provided with torsion bar spring seat 4 between permanent seat 3 and torsion bar spring 8.Described left shaft holder 5 connects the first oil nozzle 6.
Chopper rotating shaft 1 right-hand member connects right bearing seat 12 by combination bearing 13, and right bearing seat 12 is provided with the second oil nozzle 14.
Chopper rotating shaft 1 connects spacing panel seat 10, spacing panel seat 10 fixes positioning plate 11.
Principle of work of the present invention is: during work, and external motor driven gear rotates, and gear transmission drives the cam on same camshaft to rotate.The rotation of cam promotes the grip block up-and-down movement of upper contact, and grip block drives again the chopper frame up-and-down movement in chopper rotating shaft 1.Chopper frame front end is provided with chopper, and control pumping of chopper by the rotation of cam, its reciprocating impact power is less, and impact acceleration is less, and reciprocating travel is less, improves work efficiency.
