The working principle of the invention is as follows: the driving gear 13 rotates to stir the transition gear 14 to move, when the paper tube 40 and the die 30 are adhered firmly, the transition gear 14 cannot drive the rack 11 to move through the spring 16, the transition gear 14 repeatedly vibrates under the driving of the driving gear 13 and the action of the spring 16, the repeated vibration repeatedly pulls the die 30 through the rack 11, the repeated pulling is more beneficial to the separation of the paper tube 40 and the die 30 until the paper tube 40 and the die 30 are separated, after the transition gear 14 pulls the spring 16, the rack 11 can be pulled forward by the pulling force of the spring 16, the moved rack 11 is meshed with the driving gear 13, then the driving gear 13 drives the rack 11 to move, the die 30 is continuously pulled forward to complete the separation of the die 30 and the paper tube 40, and the whole tube removing operation is completed after the paper tube 40 is removed from the rear portion.

Of course, it is also necessary to supplement that the spring force coefficient of the spring 16 match the moving friction coefficient of the die 30, and that the spring force coefficient provided when the spring 16 is expanded is capable of pulling the die 30.

When the die 30 and paper tube 40 are released and gradually pulled free, the press ring 23 may damage the paper tube, requiring a machine to unwind the press ring 23 at the rear and then the press ring 23 at the front, at which point the paper tube 40 can be easily removed manually.

The above embodiments mainly illustrate the straight pull type insulation paper tube removing machine of the present invention. While only a limited number of embodiments and features have been described, those skilled in the art will recognize that the invention can be embodied in many other forms without departing from the spirit or scope thereof.
