And the air cylinder 2, the first motor 21 and the second motor 22 are all connected with a PLC (programmable logic controller).

The utility model discloses a theory of use as follows:

as shown in fig. 1 and 3, firstly, the adhesive tape to be processed is placed on the first reel 31, and the exposed surface of the adhesive tape is provided with an adhesive layer, the adhesive tape is manually pulled out and brought into the positioning groove 121, the adhesive tape is pulled through the blanking hole 15 and then continuously pulled through the upper flat surfaces of the three semicylinders 13, and finally, the adhesive tape extends out of the positioning groove 121 and is bonded and wound with the first reel 211, wherein the part of the adhesive tape in the positioning groove 121 is parallel to the upper flat surfaces of the three semicylinders 13 (shown by the corresponding dotted line position in fig. 2), the adhesive tape cannot be bonded with the roller 13 and is bonded and folded in the conveying process, and meanwhile, the groove shape of the positioning groove 121 ensures the smoothness of the surface of the adhesive tape, that the groove width of the positioning groove 121 can be adapted, the combination pressing plate 12 is screwed and fixed on the lower template 11, and the adjustment is convenient and fast.

Then, the bottom film is placed on the second reel 32, and is manually pulled out and brought into the guide groove 111, and is pulled through the feeding hole 15 and then is pulled through the lower end wheel surfaces of the three semi-cylinders 13, and finally is extended out of the guide groove 111 and is wound and connected with the second rotating shaft 221, wherein the part of the bottom film in the guide groove 111 is in a fit state with the lower end curved surfaces of the three semi-cylinders 13 and is also in a fit state with the lower end groove wall of the guide groove (shown by the corresponding dotted line in fig. 2), the formed cutting block 14 rapidly drives the formed adhesive tape to move to and finally be bonded with the bottom film after being fed, and the fit state of the upper and lower end surfaces of the bottom film reduces a moving space, so that firm bonding can be ensured, the situation that the adhesive tape is bonded and offset due to moving can be avoided under the influence of the pressure of the air cylinder 2, and the uniform distance between feeding and bonding can be ensured.

Then, starting to test the mold, adjusting the output pressure in the cylinder 2 according to the blanking condition, debugging to a proper blanking state, and finally setting the rotating speed and the stepping frequency of the first motor 21 and the second motor 22 to be consistent on a PLC (programmable logic controller) (not marked), namely starting normal processing; like this, under the condition of sticky tape and basement membrane synchronous motion, the sticky tape part laminating after the shaping unloading is on the basement membrane, the remaining rim charge of shaping can not contact the basement membrane, and the product only needs the fashioned piece of bulge 141 (as shown in fig. 4 blanking hole corresponds the shape), the shaping rectangular part of shaping stripping 14 unloading on the one hand prevents the shaping of bulge 141 position from wandering away, on the other hand is the shaping part of being convenient for take off bulge 141 smoothly under the adhesion state of glue film and corresponding, can assemble the use after the pruning, avoid getting the material and take place fold and turn-up.

In addition, it should be noted that, in order to prevent the adhesive tape from being discharged and from being folded in an offset manner during the process of being bonded with the bottom film, the upper end groove wall of the guide groove 111 is provided with the semi-cylinder 13, and in order to avoid the adhesive layer of the adhesive tape from being carried with impurities to affect the transfer bonding, the semi-cylinder 13 is only arranged in the discharging direction, the straight surface at the upper end of the semi-cylinder 13 is parallel to the adhesive tape, and similarly, the curved surface at the lower end of the semi-cylinder 13 is attached to the upper end surface of the bottom film, and the lower end surface of the bottom film is attached to the lower end groove wall of the guide groove 111, and because the two rotating shafts and the two reels correspondingly stretch the adhesive tape and the two ends of the bottom film, the curved surface end of the semi-cylinder 13 ensures that the bottom film keeps flat in the moving process.

Similarly, the limiting block 18 arranged along the feeding direction can better keep the stability of the feeding direction of the bottom film and avoid the deflection of the blanking bonding.
