[0036] Please refer to Figures 1-5 , the present utility model provides a technical solution: a vacuum adsorption device with flexible bottom support positioning and adjustment, including:

[0037] A positioning platform 1, with a positioning groove 11 opened at its top, and a plurality of adsorption ports 12 opened at the bottom of the positioning groove 11;

[0038] A pumping and pressing connecting member 2, whose end is docked with the adsorption port 12 and an external negative pressure motor;

[0039] A first base 3, which is detachably assembled on one side of the positioning platform 1 by bolts;

[0040] A second base 4, which is detachably assembled on the other side of the positioning platform 1 by bolts, and has a first mounting hole 41 provided on its side;

[0041] A support seat 5, which is arranged inside the second base 4, and a second mounting hole 52 is arranged along the length direction on the bottom side plate 51 of the support seat 5. Both the first mounting hole 41 and the second mounting hole 52 are string-like structures formed by linearly connecting the sides of a plurality of cylindrical screw holes in sequence;

[0042] A fastener 6, which is screwed and matched with the cylindrical screw hole to position the second base 4 and the support seat 5, and the support seat 5 and the ground. A spacer 7 is arranged between the fastener 6 and the cylindrical screw hole.

[0043] A guide block is arranged on the outer wall of the outer end of the pumping and pressing connecting member 2, and the guide block is slidably connected with a chute axially extending on the inner wall of the connecting pipe joint docking the negative pressure motor. An external thread is arranged on the outer wall of the inner end of the pumping and pressing connecting member 2, and the external thread is screwed with an internal thread on the inner wall of the connecting pipe joint. An annular avoidance groove corresponding to the guide block is arranged at the inner end of the chute on the inner wall of the connecting pipe joint. Through the multi-layer structure formed by the above-mentioned guide block and external thread, it is convenient for it to be docked with the connecting pipe joint, and at the same time, the airtightness of the interface is improved.

The above design can cooperate with the embedded design of the backing plate 7 and the countersunk groove, and the positioning strength of the backing plate 7 is improved by plugging the positioning column 71 into the cylindrical screw hole, thereby preventing the backing plate 7 from moving and thus preventing the fastener 6 from loosening.

[0048] An elastic member 72 is provided between the backing plate 7 and the fastener 6 to pre-tighten the assembly structure of the fastener 6, the backing plate 7 and the mounting hole, thereby further ensuring the assembly strength.

[0049] The working principle of a vacuum adsorption device with flexible bottom support positioning adjustment in this embodiment includes: based on the use requirements, different sizes of positioning platforms 1, first base 3, and second base 4 are selected and assembled and shaped on-site in the printing production workshop by bolts, and the mounting holes of the support seat 5 are aligned based on the holes pre-punched on the on-site ground, and the support seat 5 is abutted against the second base 4; the pad 7 and the positioning column 71 are respectively inserted into the countersunk groove and the mounting hole, and then the elastic member 72 is sleeved on the fastener 6, and the fastener 6 is screwed and positioned in the mounting hole to complete the positioning of the support seat 5 with the vacuum adsorption device and the ground; one end of the connecting pipe is connected to the negative pressure motor, and the other end is inserted and screwed through the connecting pipe joint to connect it with the pumping connector 2. When in use, the object to be printed is placed in the positioning groove 11, and the negative pressure motor is started to generate negative pressure in the adsorption port 12, and the object is adsorbed and positioned, and the printing operation of the printing press can be carried out.

[0050] In summary, due to the adoption of the above technical solution, the vacuum adsorption device with flexible bottom support positioning adjustment in this embodiment has the following beneficial effects compared with the prior art:

[0051] The vacuum adsorption device of the present utility model adsorbs and positions the object to be printed through the adsorption port. The whole adopts a detachable design, which is convenient for the convenient disassembly, assembly and size adjustment according to the use requirements of different objects to be printed, printing machines and operators. Moreover, the support and reinforcement of the above structure are realized through the cooperation of the support base, the string-shaped mounting hole structure and the fasteners, which can facilitate the adjustment and positioning of the docking positions with the second base and the ground, without the need for additional drilling, improving the use efficiency, and ensuring the structural strength through the cooperation of the backing plate, the positioning column and the mounting hole.
