Pressure valve, the surface of the gas collection box (27) is connected to the bellows (25) through the breather tube (28), the breather tube (28) covers the air outlet, and the gas collection box (27) passes through the gas collection component Collect energy. 7. A new type of polyester webbing production equipment with photochromic properties according to claim 6, characterized in that the gas collecting component includes a hollow frame (29) fixedly installed in the lower pressing block (4) , the sliding seal of the bottom end of the piston block (6) located in the pressure block (4) below is inserted into the hollow frame (29), and the hollow frame (29) passes through the air inlet pipe (30) and the air outlet pipe respectively. (31) is connected to the outside world and the air collecting box (27), and the air outlet pipe (31) and the air inlet pipe (30) are both equipped with second one-way valves. 8. A production process for a new type of polyester webbing production equipment with photochromic properties, characterized in that the production process includes the following steps: S1: First, wrap one end of the webbing (100) soaked in the cleaning liquid around the winding roller, and make the webbing (100) pass between the two pressing blocks (4). At this time, control the winding roller to rotate. The ribbon (100) is rolled up, and at the same time, the drive motor is started to control the rotation of the reciprocating screw (2). The ribbon (100) will pass through the inside of the drying equipment during the process of being rolled up; S2: During the rotation of the reciprocating screw rod (2), the slide plate (3) threaded on the reciprocating screw rod (2) will reciprocate in the vertical direction, so that the two pressing blocks (4) will The upper and lower surfaces of the webbing (100) will be pressed intermittently; S3: The webbing (100) is pressed by the two pressing blocks (4) and will intermittently assume a positive V shape and an inverted V shape. During the pressing process, the liquid contained inside the webbing (100) can be squeezed out. This achieves the effect of pre-dehydrating the webbing (100) before entering the drying equipment, which facilitates subsequent drying processing; S4: After the webbing (100) is rolled up, remove the rolled webbing (100) to obtain the dried webbing (100).
