Description

Wrap-up

Technical field

The utility model relates to the printing of volume to volume formula, die cutting equipment, relates in particular to a kind of wrap-up.

Background technology

Present printer, the mould cutting machine that uses, its wrap-up generally adopts opto-electronic pickup, whether before wrap-up, stored into certain-length to judge by Roll Sushi, if drive the angle of Scroll rotational fixation so by power-transfer clutch, receive rotating shaft then and stop, waiting for induction next time again.The cost height that to adopt this mode one be wrap-up, the 2nd, be in fluctuation status all the time by the tension force of Roll Sushi, rolling is inhomogeneous, influence printing, cross cutting effect.

The utility model content

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part and provides that a kind of cost is low, tension force pulsation-free wrap-up.

The purpose of this utility model can be achieved through the following technical solutions:

Wrap-up comprises connector, motor, and motor is installed on the connector by motor mount plate; It is characterized in that, wear a mandrel in the captive joint mode on the connector, the axle center of mandrel and the axis parallel of motor output shaft; Pass through a needle bearing on the mandrel with rotary way suit one belt pulley, suit one thrust baring between belt pulley and the connector; Also pass through two needle bearings on the mandrel with rotary way suit one rolling cylinder, two needle bearing two end settings of close rolling cylinder respectively; Be provided with ring-type brake pad between mandrel and the belt pulley, brake pad also are sleeved on the mandrel; Go back suit one compression spring on the mandrel, be provided with a thrust baring between compression spring and the rolling cylinder end away from brake pad, thrust baring also is sleeved on the mandrel; Mandrel not with connector bonded assembly one end by the setting nut that has been threaded, setting nut is arranged on the end of described compression spring away from thrust baring.

Wrap-up is characterized in that, suit one baffle ring and an awl baffle ring on the described rolling cylinder, baffle ring has the face of cylinder, a cylindric place, the awl baffle ring has an outer conical surface, and the small end of the described face of cylinder and described outer conical surface is provided with in opposite directions, is respectively equipped with a lock screw on baffle ring and the awl baffle ring.

Wrap-up is characterized in that, the setting nut that described mandrel is provided with has two.

The wrap-up that the utility model relates to adopts conventional mechanical mode, the contrast prior art, and its cost is than low many of opto-electronic pickup and magnetic clutch, thereby has the low advantage of cost.The utility model is provided with a predetermincd tension by spring and gives brake pad on the other hand, the time real automatic guidance by the tension force of Roll Sushi, predetermincd tension is provided with under the normal circumstances, does not store before the wrap-up by Roll Sushi; Therefore compare with the existing technical scheme of opto-electronic pickup that adopts, have tension force pulsation-free advantage.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.Present embodiment is a kind of wrap-up, comprises connector, motor, and motor is installed on the connector by motor mount plate; Wear a mandrel in the captive joint mode on the connector, the axle center of mandrel and the axis parallel of motor output shaft; Pass through a needle bearing on the mandrel with rotary way suit one belt pulley, suit one thrust baring between belt pulley and the connector; Also pass through two needle bearings on the mandrel with rotary way suit one rolling cylinder, two needle bearing two end settings of close rolling cylinder respectively; Be provided with ring-type brake pad between mandrel and the belt pulley, brake pad also are sleeved on the mandrel; Go back suit one compression spring on the mandrel, be provided with a thrust baring between compression spring and the rolling cylinder end away from brake pad, thrust baring also is sleeved on the mandrel; Mandrel not with connector bonded assembly one end by the setting nut that has been threaded, setting nut is arranged on the end of described compression spring away from thrust baring; Suit one baffle ring and an awl baffle ring on the rolling cylinder, baffle ring has the face of cylinder, a cylindric place, and the awl baffle ring has an outer conical surface, and the small end of the described face of cylinder and described outer conical surface is provided with in opposite directions, is respectively equipped with a lock screw on baffle ring and the awl baffle ring.The setting nut that described mandrel is provided with has two.

Baffle ring 17 and awl baffle ring 20 are locked on the rolling cylinder 18 by baffle ring lock screw 5, are used for adjusting and fixing rolling barrel.Motor mount plate 9 usefulness screw lock are on connector 11, and axle 19 is installed on the connector 11, and junctor 11 is locked at whole device on the working machine by lock screw 12.Motor 10 is locked on the motor mount plate 9, and belt pulley 7 is housed on the output shaft of motor 10.Be installed on the mandrel 19 by needle bearing 14, can rotate.Rolling cylinder 18 is installed on the mandrel 19 by needle bearing 4 and needle bearing 16, can rotate.On mandrel 19, belt pulley 6 one sides are close on connector 11 by thrust baring 13, realize axial location.Between belt pulley 6 and rolling cylinder 18, accompany friction shoe 15.Setting nut 1 is pressed on spring 2 on the rolling cylinder 18 by thrust baring 3.The outside of setting nut 1 can install a black nut additional.Motor 10 sends turning effort to belt pulley 6 by belt pulley 7 and belt conveyor 8, belt pulley 6 sends turning effort to friction shoe 15 again by rubbing effect, and friction shoe 15 sends turning effort on the rolling cylinder 18 of carrying out rolling work in the mode of rubbing effect equally.By the rolling material tensile is arranged between wrap-up and the upper working machine, friction shoe 15 has a balance with producing friction force between belt pulley 6 and the rolling cylinder 18 between these two power all the time.When thereby upper working machine dispensing speed quickening tensile reduced, friction force had the gesture of driving greater than tensile, rolling cylinder 18 faster rotational speed, and order is strained by roll of material, forms a balance again.When upper working machine dispensing speed slows down or shuts down and when tensile is increased, produce and slide, reach a balance between slip kinetic force of friction and the tensile between friction shoe 15 is with belt pulley 6 and rolling cylinder 18.During use,, can reach a state that a suitable force of sliding friction is arranged all the time in wrapup procedure, thereby stablize rolling tension force by adjusting setting nut 1.
