Description

Technical Field

[0001] This utility model relates to the technical field of filter rod forming equipment, specifically to a docking wheel adjustment mechanism and a composite filter rod forming machine. Background Technology

[0002] The composite filter rod forming machine consists of a combination machine and a forming machine. It initially cuts different types of filter rod strips into filter rods, combines them in sequence, and conveys them to the forming machine to roll them into shape. The combined filter rod strips are then cut into qualified single filter rods, which are finally output through a conveying device.

[0003] Composite filter rod forming units use conveyor wheel sets (i.e., docking wheel sets) to transport two or more filter rods of different lengths for compounding. Since the specifications of the composite filter rods differ, the length ratios of the combined filter rods will also differ. Existing conveyor wheels are directly assembled into the frame through holes and their positions cannot be adjusted. Therefore, the center distance between adjacent conveyor wheels remains constant, and existing conveyor wheel sets cannot meet the conveying requirements of composite filter rods of various specifications. Utility Model Content

[0004] The purpose of this utility model is to provide a docking wheel adjustment mechanism and a composite filter rod forming machine, which can conveniently adjust the center distance between adjacent conveying wheels in the conveying wheel group to meet the conveying needs of composite filter rods of various specifications.

[0010] On the other hand, this utility model provides a composite filter rod forming machine based on the above-mentioned docking wheel adjustment mechanism, including a frame, on which a positioning hole is provided, and the positioning plate is detachably installed at the positioning hole.

[0011] Optionally, a back plate smaller than one circle is fixedly provided on the back of the positioning plate, and the positioning hole is shaped like a truncated ring with a larger front and a smaller back.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Please refer to Figure 1 and Figure 2 As shown, this embodiment proposes a docking wheel adjustment mechanism, including a positioning plate 1. The positioning plate 1 has various specifications. A through hole 101 is provided on the positioning plate 1. The position of the through hole 101 is different for different specifications of positioning plates 1. A rotating shaft 2 is rotatably provided at the through hole 101. A docking wheel 3 is fixed at the front end of the rotating shaft 2.

[0021] Based on the above embodiment, the back of the positioning plate 1 is integrally provided with a sleeve 103, which is coaxially arranged with the through hole 101. Two bearings are sleeved along the inner edges of the through hole 101 and the sleeve 103, and a rotating shaft 2 is installed on the inner ring of the bearing. A synchronous pulley 4 is fixedly provided at the rear end of the rotating shaft 2. The synchronous pulley 4 is powered by an external motor in conjunction with a synchronous belt. The design of the sleeve 103 increases the effective axial fixing length of the rotating shaft 2 and improves the stability of the rotating shaft 2 during operation.

[0022] Based on the above embodiments, the positioning plate 1 is a polygonal plate. In this embodiment, it is preferably a rectangular plate. The rectangular positioning plate 1 has circumferential stability after assembly. Compared with a circular plate, a circular plate is prone to loosening of bolts due to shaking.

[0023] On the other hand, this embodiment proposes a composite filter rod forming machine based on the above-mentioned docking wheel adjustment mechanism, including a frame with positioning holes. A positioning plate 1 is detachably installed at the positioning holes. A back plate 102 smaller than one circumference is fixedly provided on the back of the positioning plate 1. The positioning holes are shaped like a truncated cone, wider at the front and narrower at the back. Both the positioning plate 1 and the back plate 102 are embedded and assembled at the positioning holes. Specifically, the positioning plate 1 and the truncated cone-shaped portion of the positioning holes have interconnected screw holes around its perimeter. The perimeter of the positioning plate 1 can abut against the truncated cone-shaped portion of the positioning holes. Both the positioning plate 1 and the back plate 102 can be concealed and embedded in the frame. The positioning plate 1 and the back plate 102 are then fixed at the positioning holes using bolts through the screw holes, making the fixing method convenient.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
