Three：Operation principle
Mainly used for depositing balls for display shells during the production, the machine can complete such processes as spreading glue on paper tapes and wrapping balls vertically or horizontally by tape papers, etc. automatically. The machine is equipped with a semi-circular bracket and a ring winder which is fixed with a paper tape drum, a glue container and a piece of pressing plastic sheet. Rotating constantly around the display shell, the ring winder wraps the balls through the paper tape spread with glue. The low speed rotation axis and the supporting rod fixed at the bottom of the semi-circular bracket clamp and secure the display shell at the central of the semi-circular bracket and the ring winder. Besides, the rotation axis drives the display shell to rotate and to be wrapped evenly by the paper tape. Moreover, the display shell can be wrapped in different angles because the relative position of the semi-circular bracket to the machine bracket can be adjusted.
Firstly, clamping the securing the display shell between the low speed rotation axis and the supporting rod of the semi-circular bracket manually. Pressing-in and letting the front end of the paper tape pass through the glue container. Wrapping the display shell with the paper tape. After that, starting up the machine. While the ring winder takes the glue container and the paper tape drum to rotate in high speed around the display shell, the display shell rotates lowly along with the slow speed rotation axis and eventually is wrapped by the paper tape uniformly. After the display shells rotates a circle, he relative position between the semi-circular bracket and the machine bracket will be adjusted to the next given angle automatically where the display shell is ready for the next process of wrapping with tape paper. The machine won’t stop automatically unless all the given volume of paper tape has been consumed in this way. Cutting the paper tape and then the machine will be re-started. The paper tape wrapping on the display shell will be compressed and shaved by the pressing plastic sheet. The machine will automatically stop again after the slow speed rotation axis takes the display shell finish all the given circles of rotation. At that time, the whole process will be finished by taking down the wrapped display shell manually.
