Technical field
The utility model relates to a kind of rotating shaft, relates in particular to a kind of vacuum rotating shaft that is used for digital printer.
Background technology
At present, during digital printer work, need be that workbench provides vacuum through vavuum pump; Be that ganoid workpiece such as glass, acrylic board on the air-breathing adsorption orifice that will place workbench of vavuum pump adsorbs; So that digital printer carries out various operations to the workpiece that is adsorbed the location, and need set up the air transfer passage between vavuum pump and the adsorption orifice, present way generally is with tracheae vavuum pump directly to be connected with adsorption orifice; When the vacuum pump work; Air in the adsorption orifice is extracted out by vavuum pump through tracheae, thereby forms vacuum, and workpiece will be pressed on the adsorption orifice by ambient atmosphere like this.Yet existing thisly have the defective that can not be ignored with tracheae with vavuum pump and the direct-connected mode of adsorption orifice: tracheae is easy to twine when workbench rotates, and what influence was produced normally carries out, thereby has reduced operating efficiency.
The utility model content
To the deficiency of prior art, the purpose of the utility model is intended to provide a kind of vacuum rotating shaft that is used for digital printer, and it can avoid tracheae to twine.
For realizing that above-mentioned purpose the utility model adopts following technical scheme:
A kind of vacuum rotating shaft that is used for digital printer; Comprise rotary body, axis of rotation, Connection Block, adpting flange, crossover sub and tracheae; Said axis of rotation is installed in the rotary body; The sidewall of axis of rotation is provided with two air channels, has two passages of corresponding connection with two air channels in the axis of rotation, and two passages extend to the lower surface of axis of rotation; The outer race of this axis of rotation is connected to two bearings that are connected with rotary body, is connected with first micro connector of two corresponding connections with two air channels on the sidewall of rotary body; The upper surface of Connection Block is provided with first recess to lower recess; The lower end of axis of rotation is fixed in first recess; The lower surface of Connection Block is provided with second recess of depression upwards, and adpting flange and Connection Block are affixed, and crossover sub places the accommodation space of the formation that flange hole surrounds of second recess and adpting flange; Connection Block is provided with two first connecting holes of corresponding connection with two passages; Crossover sub is provided with two second connecting holes of corresponding connection with two first connecting holes, and two second connecting holes are connected with one second micro connector respectively, and two second micro connectors are arranged in the flange hole of adpting flange; Tracheae is connected with adpting flange, and this tracheae is connected with two second micro connectors.
The upper end of said rotary body is provided with a rotary body lid to be opened/closed.
A kind of vacuum rotating shaft that is used for digital printer that the utility model is set forth, its beneficial effect is: this product in use, rotary body rotates with the workbench of digital printer synchronously; And tracheae does not rotate; Thereby tracheae can not twine, and this product can keep good sealing property in rotary course simultaneously, can powerful absorption glass, ganoid workpiece such as acrylic board; Shortened the time of workpiece location in the printing process greatly; Can guarantee that workpiece can not produce displacement because of external force applies in printing process, guarantee printing precision, improve production efficiency.
Description of drawings
Fig. 1 is the overall structure diagrammatic sketch of the utility model embodiment;
Fig. 2 is the exploded view of the utility model embodiment.
The specific embodiment
Come the utility model is further described below in conjunction with accompanying drawing and specific embodiment.
Shown in please seeing figures.1.and.2; It has demonstrated the concrete structure of the utility model preferred embodiment; A kind of vacuum rotating shaft that is used for digital printer comprises rotary body 10, axis of rotation 20, Connection Block 30, adpting flange 40, crossover sub 50 and tracheae 60, wherein:
Said axis of rotation 20 is installed in the rotary body 10; The sidewall of axis of rotation 20 is provided with two air channels 21; Have two passages (not marking) in the axis of rotation 20 with the 21 corresponding connections of two air channels; Two passages extend to the lower surface of axis of rotation 20, and the outer race of this axis of rotation 20 is connected to two bearings 22 that are connected with rotary body 10, are connected with two first micro connectors 11 with the 21 corresponding connections of two air channels on the sidewall of rotary body 10; The upper end of rotary body 10 is provided with a rotary body lid 12 to be opened/closed, is used to prevent that dust from getting into rotary body 10.
The upper surface of said Connection Block 30 is provided with first recess 31 to lower recess; The lower end of axis of rotation 20 is fixed in first recess 31; The lower surface of Connection Block 30 is provided with upwards second recess (not marking) of depression; Adpting flange 40 is affixed with Connection Block 30; Crossover sub 50 places 41 accommodation spaces that surround formation of flange hole of second recess and adpting flange 40, and Connection Block 30 is provided with two first connecting holes (not marking) of corresponding connection with two passages, and crossover sub 50 is provided with two second connecting holes (not marking) of corresponding connection with two first connecting holes; Two second connecting holes are connected with the flange hole 41 that one second micro connector, 51, two second micro connectors 51 are arranged in adpting flange 40 respectively; Tracheae 60 is connected with adpting flange 40, and this tracheae 60 is connected with two second micro connectors 51.
