The belt support plate 1705 is arranged between the transfer wheel assembly 4 and the transition wheel assembly 5, and is fixedly supported by the support plate bracket 1706 fixed on the installation panel 8. The transition plate 1707 is arranged at the right end of the transition wheel assembly 5, and is fixedly supported by the transition plate bracket 1708 fixed on the installation panel 8. The transition assembly 17, the transfer wheel assembly 4 and the transition wheel assembly 5 form an inclined channel for conveying the filter rod from top to bottom, so that the filter rod is smoothly conveyed downward.

[0063] The working principle of the hollow paperless filter rod end face detection and rejection device is as follows: the formed and cut filter rod enters the circumferential groove of the smoke separation wheel 102 of the smoke separation wheel assembly 1, and enters the circumferential groove of the detection wheel assembly 2 following the circular motion of the smoke separation wheel 102 under negative pressure adsorption. When the filter rod rotates to the top of the detection wheel assembly 2, the camera 1307 takes a picture of the filter rod end face, and the detection system 14 processes the picture to determine whether the filter rod end face is qualified. When the filter rod end face is unqualified, the detection system 14 provides a signal to the rejection valve 310 on the rejection wheel assembly 3, and the rejection valve 310 opens, and the positive pressure The unqualified filter rod enters the reject wheel 304. At the same time, the filter rod enters the circumferential groove of the reject wheel 304 of the reject wheel assembly 3 through the detection wheel assembly 2. When the unqualified filter rod rotates to the lower end of the reject wheel 304, the reject valve 310 is opened to connect the positive pressure to blow the filter rod, so that the filter rod falls into the reject channel 10 below the reject wheel 304 and enters the waste bucket 11 to complete the rejection of the unqualified filter rod. The qualified filter rod in the circumferential groove of the reject wheel 304 continues to follow the circumferential rotation of the reject wheel 304 and enters the transfer wheel assembly 4, and is then transported downward through the filter rod conveying channel of the transition assembly 17 into the boxing equipment.

For those skilled in the art, the present invention may be modified and varied in various ways. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
