[0109] It should be further noted that the horizontal pusher 53, the vertical pusher 54 and the material stripper 55 are preferably air cylinders.

[0110] The above only describes the preferred embodiments of the application and is not intended to limit the application; any modification, equivalent replacement and improvement made within the spirit and principle of the application shall be included in the protection scope of the application.
