[0014] Further, the vertical side of the plate material comprises the side of the plate material without the groove and the lower vertical surface below the groove of the plate material.

[0015] Further, the plurality of extrusion pieces gradually approach the groove of the plate material in the plate material walking direction.

[0016] Further, the extrusion piece is a rotating roller structure.

[0017] Further, in the S3 step, a plurality of turning wheels are used to turn up the edge sealing strip of the plate material, the turning wheel comprises a circular truncated cone turning wheel and a combined turning wheel, the upper end of the main wheel of the circular truncated cone turning wheel is provided with a circular truncated cone with a diameter gradually decreasing from bottom to top, the shape of the part of the main wheel extending outside the circular truncated cone is matched with the groove of the plate material, the combined turning wheel comprises a circular wheel and a guide block arranged at the upper end of the circular wheel, the front end of the circular wheel extends outside the guide block, and the shape of the part of the circular wheel extending outside the guide block is matched with the groove of the plate material, the front side of the guide block is inclined at an angle A of 10° to 20° to the vertical surface, the front side of the guide block of the combined turning wheel closer to the feeding direction is larger, the front side of the guide block of the last combined turning wheel is a vertical surface, and the circular truncated cone turning wheel is arranged on the side of the combined turning wheel in the feeding direction.

[0018] The effects provided in the summary are only the effects of the embodiments, not all the effects of the invention, and one of the above technical solutions has the following advantages or beneficial effects:

[0019] 1. The application finds the cause of the problem of the upper vertical surface at the beginning and end of the groove and the sealing strip not being firmly bonded, mainly because when the sealing strip is pressed into the groove, the sealing strip at the corners of the beginning and end of the groove has a large extrusion force between the upper edge of the plate side edge, under the action of this extrusion force, the glue on the back of the sealing strip is scraped off by the upper edge of the plate side edge, and the glue is stored on the top surface of the plate, and it is this part of the sealing strip with the scraped glue that is bonded with the upper vertical surface above the groove of the plate, and due to the small amount of remaining glue, the sealing strip at this position is not firmly bonded. The application first bonds the vertical side, then gradually advances the sealing strip into the groove of the plate, and presses the upper vertical surface above the groove before the sealing strip completely enters the groove, so that the glue on the sealing strip is bonded to the upper vertical surface above the groove of the plate. By transferring the glue on the sealing strip to the vertical surface above the groove of the plate in advance, the problem of the upper vertical surface at the beginning and end of the groove and the sealing strip not being firmly bonded is solved.

[0020] 2. The application completes the work of transferring glue by transferring glue rollers, the roller structure is in rolling friction with the upper vertical surface of the plate, which reduces the friction damage compared with sliding friction, avoiding scratching the pressed sealing strip; the transferring glue roller is connected with an elastic structure to make it have elasticity in the direction of the plate, on the one hand to ensure that the transferring glue roller has a certain pressure at the corners of the beginning and end of the groove, on the other hand the elasticity can make the transferring glue roller retract or extend according to the shape of the plate, without interfering with the movement of the plate.

[0021] 3. By setting the transferring glue roller to slide forward and backward, and adjusting its forward and backward position by a gas cylinder, on the one hand the forward and backward position of the transferring glue roller can be adjusted according to the depth of the upper vertical surface of the groove of the plate (i.e. the forward and backward position), so as to adapt to the processing of plates of different specifications and shapes, on the other hand the gas pressure of the gas cylinder is used as elastic potential energy, saving the cost of additionally setting elastic members.

[0022] 4. The rotating roller structure is used as an extrusion member, the friction between the sealing strip and the extrusion member is mainly rolling friction, especially when the sealing strip is not flat, the rolling friction between the sealing strip and the extrusion member greatly avoids the wear and tear problem of the sealing strip caused by the pressing device.

[0023] 5. The flanging wheel gradually and progressively bends and turns up the sealing strip of the upper vertical surface at the groove from a nearly horizontal posture to press and fit at the upper vertical surface of the groove, ensuring that the bent sealing strip is completely fitted with the groove of the plate and is smooth and wrinkle-free.
