After the equipment is moved to the corresponding work location, the support assembly drives the base 1 to rise, thereby making the driving wheels leave the ground, which can play a role in supporting and stabilizing the equipment, which is beneficial to maintaining the stability of the equipment. When the equipment is stabilized, the staff places the material on the base 1 and on top of the two lower panels 12, and then operates the correction assembly to correct the placement of the material on the base 1, so that the material is placed accurately, which is beneficial to improving the subsequent edge sealing quality of the equipment. When the material adjustment is completed, the first cylinder 9 drives the support box 8 to carry the upper panel 10 and the cutting knife 18 synchronously. The upper and lower panels 10 and 12 are pressed together by the driving force of the first cylinder 9, and the upper and lower panels 10 and 12 are then electrically heated to seal the material. A telescopic assembly is arranged between the upper and lower panels 10 and the support box 8.
