Method for manufacturing mask sheet feeding device of mask machine

- Jun 15, 2020-

Background technique:


At present, most of the masks produced by the mask manufacturing industry are manufactured by manual or semi-automatic equipment. A mask requires three to four processes to be made into a finished product. The process is quite complicated and cumbersome. In addition, the masks are produced with a simple combination of equipment. The labor cost is high and the production efficiency is low. Especially the upper belt is generally welded by the staff manually. The work intensity is large and the mechanical type is repeated. Quality problems such as wrong soldering and missing soldering occur. Therefore, it cannot meet the actual production needs of enterprises.


A mask sheet feeding device for a mask production machine, comprising an ear strap applicator frame and a bracket, the bracket is fixed at the end of the ear strap applicator frame, and the bracket is provided with upper and lower two groups Conveyor rollers, a conveyor belt is sleeved on the upper and lower groups of conveyor rollers, respectively, wherein the upper conveyor belt is pressed on the lower conveyor belt. The equipment has the advantages of compact structure, high degree of automation, easy operation, reliable operation, accurate action, high work efficiency and so on. However, this patent can only transfer the mask piece to the welding place, and cannot weld both ear straps to the mask piece at a time.

Technical realization elements:


The problem to be solved by the utility model is to provide a mask piece feeding device for mask pieces of a mask machine that completes the welding of the ear bands on both sides of the mask piece in a single clamping process, has zero manual participation, has a high degree of automation, and has a high working efficiency . To this end, the following technical solutions are now proposed:


A mask sheet feeding device for a mask machine includes a moving mechanism and a clamping mechanism, the moving mechanism includes a linear guide rail and a sliding table, the sliding table is sleeved on a sliding shaft of the linear guide rail; the clamping mechanism includes A support base, a cylinder base, a cylinder telescopic rod and an electric mask clip, the support base is fixed on a sliding table, the cylinder base is fixed on the support base, the tail end of the cylinder telescopic rod is fixed on the cylinder base, and the cylinder is telescopic The head end of the rod passes through a rotating shaft in the vertical direction, a miniature stepping motor is fixed in the telescopic rod of the cylinder, the electric mask clip is fixed on the rotating shaft, and the rotating shaft driven by the stepping motor drives the electric mask clip to rotate 180° horizontally.


Compared with the prior art, the beneficial effects of the present invention are:


(1) The utility model designs a moving mechanism and a clamping mechanism. The moving mechanism drives the clamping mechanism to take the mask piece. The moving mechanism adopts a linear guide rail, which can make the mask piece reach the welding place smoothly. The head end of the telescopic rod in the clamping device There is also a photoelectric sensor, the electric mask clip is controlled by the relay to open and close, the photoelectric sensor senses the mask piece, controls the cylinder telescopic rod to adjust the appropriate position, and then the relay controls the electric mask clip to take the mask piece, and the mask clip to take the mask piece to reach the mask At the same time, in order to be able to weld the ear straps on both sides of the mouth in one transportation process, the utility model fixes a rotating shaft at the front end of the telescopic rod of the cylinder, the rotating shaft is driven by a stepping motor, and the rotating shaft Rotating drives the mask clip to turn 180°, so that the other side of the mask can also be welded. During this process, manual zero participation can accelerate welding efficiency, save time, and work efficiently.


(2) The sliding table of the utility model is designed with multiple oiling holes to ensure the smooth operation of the sliding table on the guide rail and improve the working efficiency.

Technical characteristics:

1. A mask sheet feeding device for a mask machine, characterized in that it includes a moving mechanism and a clamping mechanism, the moving mechanism includes a linear guide rail and a sliding table, and the sliding table is sleeved on the sliding shaft of the linear guide; The clamping mechanism includes a support base, a cylinder base, a cylinder telescopic rod, and an electric mask clip, the support base is fixed on a sliding table, the cylinder base is fixed on the support base, and the tail end of the cylinder telescopic rod is fixed on the cylinder On the base, the head end of the cylinder telescopic rod passes through a rotating shaft in the vertical direction, a miniature stepping motor is fixed in the cylinder telescopic rod, the electric mask clip is fixed on the rotating shaft, and the stepping motor can drive the rotating shaft to rotate and drive the electric mask clip Pan 180°.


2. The mask sheet feeding device for a mask machine according to claim 1, wherein the sliding table is provided with a plurality of refueling holes.


3. The mask clip feeding device for a mask machine according to claim 1, wherein the electric mask clip is controlled to open and close by a relay.
