When the material tape and the adhesive tape are pulled at the same time, the scraper 403 can easily separate the product and the material tape from the adhesive tape.

[0024] The toggle mechanism includes mounting plates 404 disposed on both sides of the guide plate 401, a slide groove is disposed on one side of the two mounting plates 404, and a movable opening is disposed on the sides of the two mounting plates 404 to communicate with the slide groove and allow the shaft of the bonding rubber roller 402 to pass through. A connecting slider 405 connected to the bonding rubber roller 402 is slidably disposed in the slide groove, and a pressure block 411 is disposed on the top of the mounting plate 404.

Since the end of the adhesive tape is tightened by the recovery part 50, when the retracting cylinder 302 pushes the transition roller 301 to move downward, the adhesive tape roll on the first expansion shaft 201 is pulled to release a section of the adhesive tape. When the stripping machine 10 pulls the tape, the motor drives the belt, so that the belt drives the second expansion shaft 501 to rotate, so that the second expansion shaft 501 rewinds the adhesive tape. When passing through the scraper 403, the scraper 403 retracts the product driven by the adhesive tape onto the tape to prevent the product from separating from the tape, and at the same time tears the protective film from the product. Under the adhesive force of the adhesive tape, the adhesive tape is recycled together with the protective film when it is rolled up.

The detection unit 80 includes a mounting frame fixed on the stripping machine 10 and a photoelectric sensor provided on the mounting frame for detecting the adhesive tape. When there is no adhesive tape on the adhesive tape roll on the upper discharge shaft 20, the photoelectric sensor cannot sense it because no adhesive tape passes through, and thus an alarm is issued or the machine is shut down to remind the operator to replace the new adhesive tape roll. The operator does not need to pay attention to whether the adhesive tape roll is used up at all times, thereby reducing the labor intensity of the operator.

[0028] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
