Description

One kind printing checking machine

Technical field

The utility model is related to print quality testing equipment field, more particularly to a kind of printing checking machine.

Background technology

Film or paper product are after printing, coating, because a variety of causes can leave some drawbacks and foreign matter and sky Locate in vain, it is therefore desirable to which the product after printing is detected, therefore people design checking machine and carry out the effect of the printing to such product Fruit is detected.

Checking machine is that after such product is deployed, in the presence of stroboscope, of short duration and frequency is applied to the printing surface of product Close flash of light, when rotation of the flash frequency with test product or movement velocity close to or it is synchronous when, utilize the persistence of vision of eyes Or audio video synchronization, the surface quality or operation conditions of high-speed moving object can be observed easily.

At present, Publication No. CN205786395U Chinese patent discloses a kind of checking machine, and it includes frame, is arranged at Film viewing screen in frame and the detection means being arranged in frame, the detection means include lamp bracket and are arranged at lamp bracket bottom Lampshade, light-emitting device is provided with the lampshade, the frame upper end, which is provided with, to be used to adjust lamp bracket closer or far from film viewing screen The first governor motion, the lamp bracket bottom, which is provided with, to be used for light regulating and is irradiated to the second governor motion of film viewing screen upper angle.

It is due to due to its winding production although this checking machine can facilitate the detection of operating personnel to a certain extent The wind-up roll of product is needed to be rotatably connected in frame, and is directly driven by winding motor, and whole wind-up roll is relatively fixed In frame, operating personnel change more inconvenient during wind-up roll.

Utility model content

The purpose of this utility model is to provide a kind of printing checking machine, and it, which has, facilitates operating personnel to change the excellent of wind-up roll Point.

Above-mentioned technical purpose of the present utility model technical scheme is that：

One kind printing checking machine, including frame, the detection unit in frame and the winding being rotatably connected in frame Winding motor is additionally provided with roller, frame, clutch and transmission are carried out by clutch unit between the wind-up roll and winding motor, from Closing drive link, shift fork that unit includes being slidably connected in frame and being rotatably connected in frame is used for shift fork toward polyslip Adjusting rod, drive link is provided with several spacing rings for be arrangeding in parallel, and shift fork is located between spacing ring.

It is arranged such, when operating personnel need to change wind-up roll, adjusting rod can be stirred, adjusting rod drives shift fork movement, Shift fork is slided between two spacing rings, so as to the related drive link of spacing ring be stirred to both sides, so that by drive link with winding Roller is separated, and wind-up roll can just be braked and changed by such operating personnel, and after replacing is finished, operating personnel can Adjusting rod is stirred with opposite direction, so as to drive shift fork and live-roller opposite direction to slide, clutch effect is achieved, so can be square Convenient to operate personnel carry out brake hard to wind-up roll and change wind-up roll.

Further set：The output shaft of the winding motor is provided with drive bevel gear, and drive link is close to winding motor One end is provided with the matched driven wheel of differential used, and driven wheel of differential is located at the side of drive bevel gear dorsad wind-up roll.

It is arranged such, while operating personnel stir adjusting rod and depart from drive link and wind-up roll, driving gear and driven Gear is separated, and now winding motor remains idle state, and wind-up roll loses after the power of winding motor rotational deceleration and gradually Stop, when operating personnel reversely stir adjusting rod, drive bevel gear is engaged with driven wheel of differential, and winding motor can just drive Drive link and wind-up roll rotation.

Further set：The wind-up roll is fixed with internal gear close to the side of drive link, and drive link correspondence position is provided with The matched travelling gear used.

It is arranged such, when operating personnel stir adjusting rod by drive link and wind-up roll disengaging, internal gear takes off with travelling gear Run out of steam stopping from, wind-up roll, on the contrary then internal gear is engaged with travelling gear, so that drive link drives whole wind-up roll rotation Turn, so as to realize the clutch of drive link and wind-up roll.

Further set：The adjusting rod includes hand lever, swingle and the poke rod fixed in " Z " font, swingle Centre position fixed with frame.

It is arranged such, when operating personnel need to be adjusted adjusting rod and shifting block, it is only necessary to promote hand lever, it becomes possible to Swingle is set to be rotated around middle pin joint, so as to drive poke rod to stir shift fork, so as to drive shift fork and transmission Bar enters line slip, so as to realize the clutch of drive link and wind-up roll.

Further set：It is arranged with two shifting blocks on the shift fork in parallel, the end of poke rod is located between two shifting blocks And shifting block can be driven to slide.

It is arranged such, poke rod rocks under the drive of swingle and contradicted on the shifting block of both sides, and shifting block now rises To position-limiting action, then applying pressure to shifting block can just drive drive link to enter line slip, so as to realize that drive link and winding bar are nibbled Close with separating.

Further set：The wind-up roll is provided with several sliding bearings close to drive link side.

It is arranged such, the setting of sliding bearing can avoid directly contacting between wind-up roll and frame, so as to reduce machine Rotate against and wear and tear between frame and wind-up roll, protection can be played a part of to wind-up roll, extend its service life.

Further set：The frame is provided with riser, and riser is provided with the regulation machine for being used for adjusting wind-up roll tensile force Structure.

It is arranged such, governor motion can adjust the tension force of wind-up roll, while the position of wind-up roll can be finely adjusted, Facilitate operating personnel to be alignd when installing wind-up roll, can further lift winding effect of the wind-up roll for product, improve product Flatness during winding.

Preferably, the frame is provided with the fixture being additionally provided with stroboscope, frame for adjusting stroboscope angle And revolving part.

It is arranged such, operating personnel are by controlling revolving part just to drive stroboscope to be rotated, so as to stroboscope Position and direction of illumination are adjusted, so as to carry out the irradiation of proper angle to different printed articles, have checking machine more preferable Using effect.

In summary, the utility model has the advantages that：

When needing to change wind-up roll, operating personnel can stir adjusting rod, and drive link is separated with wind-up roll, so grasp Making personnel just can brake wind-up roll and be changed, and after replacing is finished, operating personnel can stir tune with opposite direction Pole, makes to be meshed between wind-up roll and drive link, can so facilitate operating personnel to wind-up roll carry out brake hard and Change wind-up roll.
