3D mask machine mask grabbing and folding device

[0015] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0016] See Figure 1-2 , The mask grasping and folding device of the 3D mask machine according to the present invention includes a vertically arranged lifting cylinder 9 and a rotating cylinder 1 arranged on the lifting cylinder 9; the rotating cylinder 1 is provided with a rotating seat 2; The rotating seat 2 is horizontally provided with a first motor 3, a first rotating shaft 4, and a second rotating shaft 5; the second rotating shaft 5 is located on one side of the first rotating shaft 4, and the first rotating shaft 4 passes through the first motor 3. Drive rotation; the rear of the first rotating shaft 4 is sleeved with a first gear 12, and the second rotating shaft 5 is sleeved with a second gear 13 meshing with the first gear 12, so that when the first motor 3 drives the first gear When a rotating shaft 4 rotates, it can simultaneously drive the second rotating shaft 5 to rotate in the opposite direction; the front ends of the first rotating shaft 4 and the second rotating shaft 5 are horizontally provided with a first grabbing block 6 and a second grabbing block 7; The lower surfaces of the first grab block 6 and the second grab block 7 are respectively provided with a plurality of air holes 8, and the upper surfaces of the first grab block 6 and the second grab block 7 are respectively provided with air holes 8 Connected tracheal sockets 21, into which trachea (not shown) are respectively inserted; the trachea can quickly reduce the air pressure in the vent 8 through air extraction, so that the 3D mask semi-finished product 11 can be firmly The ground is adsorbed on the lower surfaces of the first grabbing block 6 and the second grabbing block 7. At this time, the first grabbing block 6 and the second grabbing block 7 are driven to rotate in the opposite direction by the clockwise rotation of the first motor 3. The semi-finished 3D mask 11 can be quickly folded.

[0017] When working, the first grabbing block 6 and the second grabbing block 7 are moved to directly above the semi-finished 3D mask 11 on the assembly line through the rotating cylinder 1 and the lifting cylinder 9 to firmly adsorb the semi-finished 3D mask 11 on the first The lower surface of a grabbing block 6 and a second grabbing block 7, and then the first grabbing block 6 and the second grabbing block 7 are driven by the first motor 3 to rotate in the opposite direction to quickly fold the 3D mask semi-finished product 11, and finally through welding By machine-sealing the edges, a finished 3D mask can be formed.

[0018] Due to the application of the above technical solutions, the present invention has the following advantages compared with the prior art:

[0019] The mask grasping and folding device of the 3D mask machine of the present invention quickly and accurately grasps the semi-finished product of the 3D mask through the adsorption of the pores 8 on the first grasping block 6 and the second grasping block 7, and then passes the first grasping The relative rotation of the block and the second grabbing block can quickly and accurately fold the 3D mask semi-finished product, and the edges of the 3D mask semi-finished product can be completely aligned with high efficiency.

[0020] The above-mentioned embodiments are only to illustrate the technical concept and characteristics of the present invention, and their purpose is to enable those familiar with the technology to understand the content of the present invention and implement it, and cannot limit the scope of protection of the present invention. All equivalent changes or modifications made by the substance shall be covered by the protection scope of the present invention.
