As shown in fig. 1 and 7, finally, the V-shaped frame moves to the pressing mechanism 5, and when the V-shaped frame moves to a position between the upper supporting block 53 and the lower pressing block 51, the V-shaped frame stops, the fifth cylinder 52 is started to drive the upper supporting block 53 to ascend until contacting and supporting the bottom paper edge guard 18, at this time, the fourth cylinder 50 is started to drive the lower pressing block 51 to descend until contacting and pressing the top paper edge guard 18, so that the combination between the paper edge guard 18 and the plate 19 is tighter, after that, the fourth cylinder 50 drives the lower pressing block 51 to ascend, and then the fifth cylinder 52 drives the upper supporting block 53 to descend, so that one pressing operation is completed, as an embodiment of the present invention, as shown in fig. 1, the pressing mechanism 5 is provided with three pressing operations, so that three pressing operations are required to be performed on a finished product, so that an adhesive effect is better, the final product has better stability and higher impact strength. And finishing the manufacture of a finished product, and repeating the steps to realize batch production.

All stations of the equipment are shifted by transmission of the transmission chain, the time interval of the shifting of the transmission at every time is based on the station with the largest number in use, the equal interval of the interval of each station is consistent with each interval on the chain, a plurality of products can be produced simultaneously, the production speed can be increased while the production efficiency is improved, better benefits are obtained, the operation is independently completed on each station after the step is performed at every time, the edge protection mechanism 2, the plate mechanism 4 and the glue spraying mechanism 3 are provided with infrared sensors for monitoring the residual situation of materials, when the situation that the paper edge protection water tank 18 and the plate 19 are in shortage or glue shortage is met, the whole equipment stops working and gives an alarm, and the normal operation of production is guaranteed.

The foregoing is a more detailed description of the invention in connection with specific preferred embodiments and it is not intended that the invention be limited to these specific details. For those skilled in the art to which the invention pertains, several simple deductions or substitutions can be made without departing from the spirit of the invention, and all shall be considered as belonging to the protection scope of the invention.
