Detailed description of the invention
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Printing rod of the present utility model is installed on printing machine to print the flexible pipe be placed on printing rod.Please refer to Fig. 1 and Fig. 2, printing rod 1 of the present utility model has and is roughly columned profile, and it comprises hollow cylindrical body 2, compressing member 3, O RunddichtringO 4 and breather pipe 5.Compressing member 3 is arranged on the head end for accepting flexible pipe 6 of hollow cylindrical body 2.It is inner that breather pipe 5 is arranged on hollow cylindrical body 2, its two ends respectively with hollow cylindrical body 2 tail end and compressing member 3 corresponding matching, and carry out hermetic seal with O RunddichtringO 4.
Hollow cylindrical body 2 tail end is for being releasably attached to printing machine by printing rod 1, the inside of hollow cylindrical body 2 tail end arranges the stage portion (non-label) outstanding to centre, stage portion surrounds the air admission hole 21 with hollow cylindrical body 2 concentric, and air admission hole 21 is connected with the compressed air source of printing machine.Hollow cylindrical body 2 is also provided with the multiple steam vents 22 being close in the long position of its tail end about 3/to four/4ths rod, steam vent 22 arranges around hollow circular cylinder 2 and is uniformly distributed in circumferentially same on the axle center of hollow circular cylinder 2 of the center of circle.Screw thread (non-label) is provided with inside the head end of hollow cylindrical body 2.
Compressing member 3 comprises the ring bodies (non-label) being roughly vaulted main body (non-label) and extending from body normal.The external diameter of ring bodies is less than the maximum outside diameter of main body, and the maximum outside diameter of main body is roughly the same with the external diameter of hollow cylindrical body 2.Be provided with screw thread outside ring bodies 33, inner side is provided with boss.The return-air hole 32 of the gas hole 31 compressing member 3 being also provided through the radial direction of ring bodies and the axis of simultaneously passing ring bodies and main body.Wherein, gas hole 31 is positioned at the ring bodies position crossing with main body.Compressing member 3 is fixedly attached to the head end of hollow cylindrical body 2 by the screw thread outside its ring bodies 33, and after compressing member 3 is fixed to hollow cylindrical body 2, gas hole 31 still communicates with outside.
Breather pipe 5 is hollow cylinder, its to be installed in hollow cylindrical body 2 and with hollow cylindrical body 2 concentric.Two ends of breather pipe 5 are respectively equipped with annular groove (non-label), the annular groove at the two ends of breather pipe 5 respectively with the boss corresponding matching of the stage portion of hollow cylindrical body 2 tail end and the ring bodies 33 of compressing member 3.O RunddichtringO 4 is arranged in the annular groove of breather pipe 5, for sealing gas.The thickness of breather pipe 5 is less than the thickness of hollow cylindrical body 2 tail end stage portion, thus forms gas passage between breather pipe 5 outside and hollow cylindrical body 2.Breather pipe 5 inside communicates with the air admission hole 21 of hollow cylindrical body 2 and the gas hole 31 of compressing member 3, and breather pipe 5 outside communicates with the return-air hole 32 of compressing member 3 and the steam vent 22 of hollow cylindrical body 2 with the gas passage formed between hollow cylindrical body 2.
Fig. 1 illustrates the gas flow of flexible pipe when sending pipe and the operation of de-pipe that first head republishes.Please refer to Fig. 1, stock plastic hollow flexible pipe 6 comprises tube head 61 and pipe shaft 62, and when sending pipe, tube head 61 is closed, and the end section of pipe shaft 62 imports in advance through compressing member 3 and is wrapped in hollow circular cylinder 2 outer surface.Now, because pipe shaft 62 and hollow circular cylinder 2 are interference fit, the magnitude of interference is 0.1-0.3mm, and thus, the part pipe shaft 62 do not imported only is difficult to smooth and easy importing under the effect of mechanical thrust.The radial gas hole 31 entered in breather pipe 5, again on compressing member 3 by the air admission hole 21 at hollow circular cylinder 2 afterbody center when compressed air is blown into, part air-flow enters in the gap between pipe shaft 62 and hollow circular cylinder 2, flexible pipe 6 is expanded, thus the fit clearance between hollow circular cylinder 2 surface increasing pipe shaft 62 and printing rod 1, make the pipe shaft 62 that imports not yet completely can be completely pushed on printing rod 1.Another part air-flow then flows in the tube chamber of flexible pipe 6, and it discharges after flowing through the return-air hole 32 on compressing member 3 from the steam vent 22 hollow circular cylinder 2.When the pipe shaft 62 of flexible pipe 6 is all pushed and is wrapped the outer surface of hollow circular cylinder 2, cut off compressed air, because pipe shaft 62 and hollow circular cylinder 2 are interference fit, therefore pipe shaft 62 very snugly can be wrapped in the surface of hollow circular cylinder 2, can not displacement be produced between pipe shaft 62 and hollow circular cylinder 2 during printing, thus ensure that the cover position precision of printing.
When being completed for printing de-pipe, the radial gas hole 31 that air-flow also enters in breather pipe 5, again on compressing member 3 through air admission hole 21 is blown into, part air-flow enters the gap between pipe shaft 62 and hollow circular cylinder 2, flexible pipe 6 is expanded, another portion is blown in the tube chamber of flexible pipe 6, now, scrape by pipeline scraper (not shown) smooth and easy for flexible pipe 6 thus complete de-pipe.
Fig. 2 illustrate the flexible pipe first printing again head send pipe and de-pipe operation time gas flow.Please refer to Fig. 2, when sending pipe, the end section of pipe shaft 62 imports in advance through compressing member 3 and is wrapped in hollow circular cylinder 2 outer surface, the radial gas hole 31 that compressed air is entered in breather pipe 5, again on compressing member 3 by the air admission hole 21 at hollow circular cylinder 2 afterbody center is blown into, part air-flow enters the gap between pipe shaft 62 and hollow circular cylinder 2, flexible pipe 6 is expanded, fit clearance between pipe shaft 62 and hollow circular cylinder 2 surface increases, and the pipe shaft 62 imported not yet completely can completely pushedly extremely be printed on rod 1.Another part air-flow is then blown in the tube chamber of flexible pipe 6, and now, a part of air-flow is discharged from the open end of flexible pipe 6.
When being completed for printing de-pipe, the transport process of air-flow is identical with sending pipe process, air-flow from the radial gas hole 31 compressing member 3 be blown into flexible pipe 6 is expanded time, scraped de-pipe by pipeline scraper (not shown) by smooth and easy for flexible pipe 6.
The beneficial effects of the utility model are: by improving the fits kind between printing rod and flexible pipe pipe shaft, the fit clearance of the two is reduced in printing process on the one hand from structure, produce between flexible pipe and printing rod when avoiding printing and be shifted, thus improve chromatography precision and printing quality.On the other hand, by the transport by means of air-flow, increase flexible pipe pipe shaft and the printing rod fit clearance sent in the de-pipe operating process after manage and print before printing, thus can solve simultaneously printing be shifted and smooth and easy send manage, take off pipe produce between the contradictory problems that exists because of fit clearance.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
