The lifting cylinder 412 is a TN20×200S model.

[0048] As attached Figure 7 , 8 As shown in Figure 19, when the large sheet pressing and holding device 4 of this utility model is working, after the six large sheet gripping and holding devices 3 hold the large sheet 9 that is delivered, the piston rod of the pressing reciprocating cylinder 402 extends from its original position and sends the pressing disc 413 installed at the lower end of the Z-shaped connecting plate 401 to the top of the laying head mold 601, that is, the center of the large sheet 9. The piston rod of the lifting cylinder 412 extends and drives the pressing disc 413 to descend, pressing the heat-resistant silicone disc 408 onto the large sheet 9 and the center of the top surface of the laying head mold 601. At this time, the heating rod 414 has been energized and the temperature has been raised to 60℃~70℃. At the same time, the piston rod of the reverse thrust cylinder 408 rises from its original position and pushes the top plate 409 to the bottom surface of the slide rail B404, and transmits the pressure down to the top surface of the laying head mold 601, and holds it until the laying of one large sheet 9 is completed. After completion, the piston rod of the reverse thrust cylinder 408 retracts to its original position, the piston rod of the lifting cylinder 412 rises to its original position, and the pressing and bonding reciprocating cylinder 402 retracts from its out position to its original position. The entire action is to ensure that the large and small material pieces are positioned and do not move on the laying head mold 601, and that the pressing and bonding quality is stable. Specifically, it prevents the large material piece 9 from shifting in any direction due to slight differences in the timing of the actions of the six large material piece holding devices 3 during the laying process, which can lead to problems such as excessive pneumatic components and excessive air consumption. This can cause misalignment of the large material piece 9, resulting in the six material petals of a large material piece 9 being of different lengths on the laying head mold 601. This would cause some areas to have too much material and some areas to have too little material after the helmet is pressed, affecting the quality of the bulletproof helmet. The electric heating pressing and bonding is to ensure that each layer of material piece is stacked and bonded together to the maximum extent at the top of the laying head mold 601 in the center of the material piece, while also completing the pressing and bonding work in the center of the material piece.

Hot air is blown to heat and soften the film, facilitating the next step of sheet laying and deformation. After heating for 3-5 seconds, the piston rods of adjusting cylinders A815 and B817 retract, returning the L-shaped small sheet hot air nozzle 812 to its original position to allow the bowl-shaped metal outer cover 716 to descend and lay the small sheet. This process improves the efficiency of the hot air blower 801 and reduces heat loss. A hot air circulation pipe 803 is installed between the air inlet 802 and the air outlet of the hot air blower 801. An air valve C804 is installed on the hot air circulation pipe 803. When the hot air volume is low or during a short period when hot air is not being blown, the air valve C804 opens, returning some or all of the hot air to the air inlet of the hot air blower 801. This increases the inlet air temperature and reduces the work done by the hot air blower. The hot air blower will automatically adjust its heating power or stop heating. The regulating cylinders A815 and B817 are also mentioned. The model of the hot air blower 801 is SHL3 / ZYD-030B.
