Description

TECHNICAL FIELD

[0001] The present application relates to a kind of paperboard tape release paper tearing mechanism, belong to carton making equipment technical field. BACKGROUND

[0002] In many electronic product production processes, the packaging of finished products will be involved, such as mobile phones and tablet computers, etc. After the finished products are manufactured, they are packaged according to categories, and products of the same category are placed in a packaging carton. The raw material of the carton is usually paperboard, which is folded to form a carton. Double-sided tape is usually attached to the paperboard before folding. The release paper on the surface of the double-sided tape must be removed before folding to expose the adhesive layer. Then, when the paperboard is folded, the adhesive layer connects the folded paperboard at the joint. Finally, a box body can be formed, and the paperboard becomes a carton. If manual operation is used, the efficiency is very low and errors are likely to occur. Therefore, a corresponding mechanical mechanism is needed to automatically tear off the release paper on the double-sided tape of the paperboard. In addition, there are multiple double-sided tapes on the paperboard, and there are creases where the paperboard has double-sided tapes. There is a height difference between the creases and other parts of the paperboard. The creases protrude from the surface of the paperboard. When the ordinary paperboard tape release paper tearing mechanism tears the release paper of the double-sided tape, the creases will push against the conventional peeling knife, and the clamping jaw cannot tear the double-sided tape, resulting in failure of the double-sided tape tearing mechanism.

[0003] Patent CN 109263243 A discloses a kind of tearing release paper device, including installation support, horizontal drive mechanism, main lifting drive mechanism, clamping assembly mounting frame, suction disc drive mechanism, suction disc, upper clamping piece, lower clamping piece drive mechanism and lower clamping piece; the main lifting drive mechanism is connected to the output end of horizontal drive mechanism; the clamping assembly mounting frame is connected to the output end of main lifting drive mechanism; suction disc drive mechanism, upper clamping piece and lower clamping piece drive mechanism are installed in clamping assembly mounting frame; the suction disc is configured to be moved downward to suck the edge of release paper or moved upward to pull the release paper under the drive of suction disc drive mechanism; the lower clamping part can move to the directly below of upper clamping part and move upward to approach the upper clamping part or move downward to move away from the upper clamping part and move out from the directly below of upper clamping part; the horizontal drive mechanism can drive the suction disc and the upper clamping part to move to the directly above of the edge of release paper or drive the edge of release paper to move in the corresponding direction to tear the release paper completely. However, the invention relies on the suction disc to suck the release paper, and then clamps the release paper to tear it off. For double-sided tape with high adhesion, the suction disc may not be able to suck the release paper, and the tearing action of the release paper cannot be completed. The tearing effect of the release paper of the double-sided tape on the paperboard with creases is also insufficient. SUMMARY

The release paper on the surface of the double-sided tape is peeled off, and then clamped. Finally, the release paper is torn off from the double-sided tape. The mechanism replaces manual operation and has high work efficiency. The pointed needle is inserted between the double-sided tape and the paperboard to lift the release paper on the surface of the double-sided tape. Then, the clamping jaw clamps the release paper and tears it off. The mechanism has good tearing effect on the release paper of the double-sided tape with high adhesion. The rotary driving cylinder is provided to rotate the whole pointed needle and clamping jaw mechanism by 180°. When the release paper of the double-sided tape at different creases is torn off, the movement track of the pointed needle and the clamping jaw is from outside to inside of the crease, so that the pointed needle and the clamping jaw are not blocked by the crease, and the paperboard is not easily damaged, thereby the release paper on the double-sided tape at the crease is smoothly torn off. The outer pointed end of the pointed needle is coated with a Teflon coating layer having anti-sticking property, so that the pointed end is not easily stuck with the glue on the double-sided tape during long time work, thereby the pointed needle can work normally for a long time. The ordinary pointed needle or clamping jaw is easily stuck with the glue on the double-sided tape during long time work, and cannot work normally when the glue on the pointed needle or clamping jaw is more and more.
