Detailed Description

In order to facilitate the understanding of the technical solutions of the present invention for those skilled in the art, the technical solutions of the present invention will be further described with reference to the drawings attached to the specification.

As shown in fig. 1 to 4, the rapid turning device of a mask machine according to the present invention comprises a mask conveying mechanism and a mask turning mechanism. The mask conveying mechanism comprises mask conveying grid bars, and the mask conveying grid bars comprise a plurality of conveying bars 1 which are arranged away from each other. Gauze mask turn-over mechanism set up in grid strip bottom is carried to the gauze mask, turn-over mechanism includes rotation axis 3, be provided with a plurality of gauze mask turn-over panels along radial direction on the rotation axis 3, gauze mask turn-over panel includes a plurality of turn-over poles 4. The width of the turnover rod 4 is adapted to the distance between two adjacent conveying strips 1. During operation, the rotating shaft 3 drives the turn-over rod 4 to rotate so as to turn over the mask conveyed on the conveying strips 1, and when the mask is turned over, the turn-over rod 4 passes through two adjacent conveying strips 1, so that the problems of interference and the like cannot occur. For ensuring to carry out better bearing to the gauze mask, ensure that gauze mask both ends and middle part all have the support, keep the steady of gauze mask, carry 1 to set up and be no less than 4, turn-over pole 4 sets up and is no less than three, realizes the balance of gauze mask. During operation, after the conveying strip 1 conveys the masks to the position where the turnover rod 4 is adapted, the turnover rod 4 rotates, the turnover rod 4 moves from bottom to top to take away the masks on the conveying strip 1, turnover is achieved, the masks are conveyed to the conveying strip 1 on the other side of the mask turnover mechanism, and the masks are conveyed out through the conveying strip 1.

In this technical scheme, gauze mask conveying grid strip both ends are provided with conveying roller 2 respectively, the conveying roller is formed by big cylinder 22 and little cylinder 21 and just coaxial setting in turn. The conveying strip 1 is arranged on the small cylinder 21, so that the problems that the conveying strip 1 is deviated in work and the like are avoided, and the problems that the conveying strip 1 is interfered with the turnover rod 4 and the like are avoided. The difference between the radiuses of the large cylinder 22 and the small cylinder 21 is smaller than the thickness of the conveying strip 1, so that the mask is conveyed on the conveying strip 1 only, and the problem that the mask is rubbed and interfered with the conveying roller 2 is avoided.

The conveying roller 2 is connected with a first servo motor, and the first servo motor is connected with a controller. Preferably, a second servo motor is connected to the rotating shaft 3, and the second servo motor is connected to the controller. Controller and servo motor's setting, the controller is used for controlling servo motor's operating speed, ensure a slice gauze mask when getting into the position that suits with turn-over pole 4, be taken away by the turn-over pole immediately, and turn-over pole transport speed should be suitable, avoid the gauze mask to carry on the one hand the landing to the rotation axis 3 in half way at the turn-over, on the other hand ensures that the gauze mask drops back on the transport strip behind the turn-over, the transport strip is at first carried away the gauze mask, the turn-over pole of transporting this slice gauze mask is passing through transport strip 1 position, avoid taking place the interference problem, once only accomplish the turn-over of a slice gauze mask, avoid appearing gauze mask stack scheduling problem.

The length of the turnover rod 4 is larger than one time of the width of the mask and smaller than two times of the width of the mask. The rotary shaft 3 is provided with a mounting hole, and the turnover rod 4 is detachably mounted on the rotary shaft 3 through the mounting hole. Different numbers of turnover rods 4 can be selectively installed according to requirements, so that the adaptability of the turnover device is improved.

Technical solution of the invention is described above with reference to the accompanying drawings, it is obvious that the specific implementation of the invention is not limited by the above-mentioned manner, and it is within the scope of the invention to adopt various insubstantial modifications of the inventive method concept and technical solution, or to apply the inventive concept and technical solution to other occasions without modification.
