detailed description

In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described below in conjunction with the accompanying drawings.

By setting a transmission mechanism with a gap on the transmission surface, the bottom of the limit side plate is extended from the gap of the transmission surface below the transmission surface, so as not to interfere with the transmission of the transmission mechanism, and it will not be between the bottom of the limit side plate and the transmission surface. There is a gap between them, which solves the problem of deviation and leakage of sheet materials during the conveying process.

The transmission mechanism with gaps on the transmission surface can be designed in a variety of different structures, and the bottom of the limit side plate can be designed according to the specific structure of the transmission mechanism, so that the bottom of the limit side plate extends from the gap of the transmission surface into the transmission surface. The following Example 1 and Example 2 give two specific structural solutions.

Example 1

As shown in Fig. 1 to Fig. 6, a shunting and conveying device for sheet materials includes a conveying mechanism and a shunt guide and limit mechanism.

The shunt guide and limit mechanism includes a limit side plate 1 arranged above the transmission mechanism, and the limit side plates 1 are vertically opposed to each other and the limit side plate 1 is parallel to the transmission direction of the transmission mechanism. The limit side plate 1 can play the role of shunt guide limit, to ensure that the sheet material maintains straight transmission. The number of limit side plates 1 is more than two. When several rows of sheet materials are fed at the same time, the corresponding number of limit side plates 1 can be set.

The shunt guide and limit mechanism also includes a limit side plate mounting beam 2 that straddles the transmission mechanism and is perpendicular to the transmission direction of the transmission mechanism. The limit side plate 1 is axially adjustable along the limit side plate mounting beam 2 It is movably installed on the limit side plate installation beam 2; the two ends of the limit side plate installation beam 2 are installed on the frame.

So that the position between the two limit side plates 1 is facing the upstream cutting and conveying sheet material. However, when adjusting the position of the limit side plate 1, if a certain limit side plate 1 needs to stay at the position of a certain conveyor belt 6, in order to achieve the purpose of reaching the bottom of the limit side plate 1 below the transmission surface, it is necessary Conveyor 6 gives way. Therefore, in this embodiment, a structure for adjusting the position of the conveyor belt is designed, and the specific structure is as follows:
