In order to more firmly clamp the silica gel film tape, the bottom surface of the tape feeding groove 301 is a plane, and a pressing plate 313 matched with the bottom surface of the tape feeding groove 301 is fixed at the end part of a piston rod of the entrainment cylinder 303.

The specific structure of the suction cup 309 capable of extending up and down is provided, a vertically arranged telescopic sleeve is arranged in the tool apron 308, the suction cup 309 is fixed at the lower end of the telescopic sleeve, and the spring 310 is arranged in the telescopic sleeve, and two ends of the spring are respectively abutted against the upper ends of the suction cup 309 and the tool apron 308. When the spring 310 is in an initial state, the sucking disc 309 is located below the annular cutter, when the sucking disc 309 is driven to move downwards, the sucking disc 309 contacts the silica gel membrane belt earlier than the annular cutter, when the sucking disc 309 continues to move downwards, the telescopic sleeve is compressed and stretched, the sucking disc 309 retracts, so that the annular cutter contacts the silica gel membrane belt to cut, when the cutting is completed and ascends, under the action of the compression elastic force of the spring 310, the sucking disc 309 resets, and the sucking disc is located below the annular cutter again. As for the sleeve pipe is not separated under the action of gravity, because the related limit structure of the sleeve pipe structure ensures, the related limit structure is designed for avoiding the separation of the two pipes in the prior common telescopic sleeve pipe, and the telescopic sleeve pipe belongs to the mature design in the field. In other embodiments, the suction cup 309 can be extended and retracted up and down by other conventional extension structures.

In order to avoid scattering of the silica gel film belt everywhere and cause interference to other constructions, two winding wheels 314 for winding the silica gel film belt are arranged on the rack, so that the smoothness of the silica gel film belt can be always ensured. Specifically, one winding wheel 314 is used for winding the uncut silica gel film tape, the other winding wheel 314 is used for winding the cut silica gel film tape, the winding wheel 314 only plays a role in winding the silica gel film tape and does not provide any power, and the step-by-step feeding of the whole silica gel film tape is realized by the tape feeding barrel, the tape feeding cylinder 302, the die cavity cover and the clamping cylinder 303. The winding wheel 314 for winding the cut silica gel membrane belt can be set to be manual, and when the cut silica gel membrane belt is too long and drooping, the winding wheel 314 is manually rotated for winding. The stepping type belt conveying structure is realized by matching a plurality of cylinders, and compared with the stepping type belt conveying realized by controlling the rotating speed of the winding wheel 314 by adopting automatic equipment, the stepping type belt conveying structure greatly saves equipment cost.
