Abstract

The utility model relates to a suspended rolled material cutting machine, which is composed of a high-speed rotary cutting mechanism, a step feeding mechanism composed of a ratchet and chains, and a positioning mechanism. The actions of the three mechanisms are operated by a trinitarian cam. The utility model has the advantages of simple structure and low cost; because of the rotary cutter and immovable cutting rolled material, heavy manual work of loading and unloading core shaft of the rolled material, etc. is relieved; the times for changing the cutter is reduced; the work efficiency and the production quality are increased.

Description

Automatic suspended rolled material cutting machine

The utility model belongs to a kind of cutting off machine, especially for the cutting off machine of the cutting of adhesive web.

General adhesive web cutting off machine all is to adopt that mandrel is clipped in rotation at a high speed on the lathe later on the coiled material string, cutting knife is only in advance and retreat radially, finishes cutting work.The loading and unloading mandrel is wasted time and energy, and labor intensity of operating staff is big, and mandrel easy deformation bending in multi-pass operation, thereby damages cutting knife, reduces cutting efficiency.Also belong to the type of this cutting off machine substantially as Chinese patent 90200042.X,, can not tackle the problem at its root, and cost is higher though done many improvement.

The purpose of this utility model is to adopt brand-new design, allows cutting knife rotate, and coiled material maintains static, and need not load onto mandrel and can finish cutting work.

Ben Qie volume machine is made up of detent mechanism, feed mechanism and cutting mechanism.Detent mechanism is used to tighten coiled material to be cut, and feed mechanism adopts the step-by-step movement feeding mode, and successive is sent into coiled material in the cutting mechanism by preseting length, and cutting mechanism can be finished the work of cutting off coiled material at autofeed, withdrawing in the rotation at a high speed.Its operation principle is referring to Fig. 1, lathe power is a motor (Fig. 1 8), its left end drives the belt pulley (Fig. 1 6) of cutting part by belt pulley, thereby make the cutting part rotation, its right-hand member drives reductor (Fig. 1 14) by a pair of belt pulley, reductor drives Trinity cam (12 of a Fig. 1,13,16) rotate, back cam (12) on this cam promotes carriage release lever (Fig. 1 9), promote rocker shaft yoke (Fig. 1 5) again, rocker shaft yoke is stirred the head axle and is moved cover (Fig. 1 4), and the head axle moves cover and drives broadwise and move cover (Fig. 1 31) and move, again by carriage release lever (Fig. 1 32) promotion articulations digitorum manus slide block (Fig. 1 30), thereby make articulations digitorum manus (Fig. 1 29) front end radial motion, drive cutting knife and realize feed, tool backlash movement.Protruding outer wheel (13) drives ratchet, ratchet (Fig. 1 18) action within on this cam, and ratchet is by chain, and chain slide block (Fig. 1 22) is moved, thereby promotes coiled material to be cut along charging slide groove (Fig. 1 23) stepping.Cam outside on this cam (16) promotes locking lever (Fig. 1 11), drives adjustable locking pull bar (Fig. 1 10) and moves radially, thereby charging locating detent (Fig. 1 24) is moved radially, coiled material to be cut is locked or unclamps, when ratchet drove the stepping of chain slide block, the charging locating detent unclamped, after treating coiled material the length charging finishing in accordance with regulations, locating detent locking, articulations digitorum manus drives the cutting knife feed simultaneously, after coiled material cuts off, and the cutting knife withdrawing, locating detent unclamps, and ratchet drives the stepping of chain slide block again.Cut coiled material is discharged by discharging opening along head axle (2) inner chamber, for alleviate the vibrations that head produces when rotating at a high speed, the head left end is equipped with bradyseism spring (3), and the bradyseism spring is contained in the hole that is distributed in head gland end face, and with head move the cover join.During every volume coiled material initial alignment, can be by adjustable position fixing handle (20) manual operation.

The utility model is owing to be that cutting knife rotates, and coiled material to be cut is motionless, so serial core axle not in the coiled material has also been exempted because of mandrel damages cutting knife and frequently changed cutter, has both exempted the manual labor of many heavinesses, has improved efficiency again.Simultaneously since be by a Trinity cam realize feed, withdrawing, coiled material stepping, lock and unclamp, so after lathe mixes up, operating accuracy height, product quality raising.

Embodiment: be described further in conjunction with the accompanying drawings.
