Description

Wheel disc installation tool of wrapping machine and matching structure of wheel disc installation tool Technical Field The invention relates to the field of tobacco machinery, in particular to a reel mounting tool of a wrapping machine and a matching structure thereof. Background A rolling machine, namely a cigarette packing machine, is a device for packing cigarettes into boxes, and common rolling machines comprise a GDX1 small box packing machine and a GDX2 small box packing machine which are designed and manufactured by Italy G.D corporation. The GDX2 small box packing machine is provided with a second wheel comprising an inner wheel disc and a cam disc, wherein a base surface of the inner wheel disc is provided with a plurality of clamp arms, each clamp arm is radially arranged along the inner wheel disc, the clamp arms are radially distributed around the circumference, one side, close to the base surface, of the inner end part of each clamp arm is hinged with the inner wheel disc through a clamp arm shaft, one side, far away from the base surface, of each clamp arm is provided with a sliding block, the cam disc is provided with a cam groove with a special-shaped structure, and all sliding blocks are required to be clamped into the cam groove simultaneously when the inner wheel disc and the cam disc are assembled. Under the loose state, a plurality of sliding blocks on the inner wheel disc are circumferentially distributed, the distribution shape of the sliding blocks is inconsistent with that of the cam grooves, so that the inner wheel disc and the cam disc cannot be directly in butt joint installation, the clamp arms are required to be controlled to rotate to a certain extent, the distribution shape of part of the cams is changed to adapt to the special-shaped structure of the cam grooves, however, the clamp arms lack a positioning mechanism, the control of the clamp arms is often only manually operated by staff, and because the inner wheel disc is provided with a plurality of clamp arms, a plurality of staff are often required to cooperate during installation, the cams on the clamp arms form a specific distribution configuration, the time and effort are consumed in the installation process, the problem of insufficient control precision can be inevitably caused during manual operation control of the clamp arms, the installation process is further complicated, and the time required for installing the second wheel by manpower alone is often more than half an hour, and the installation and later maintenance of equipment are influenced. Disclosure of Invention In order to solve the problems, the invention provides a reel disc mounting tool of a packaging machine, which can directly assemble a cam disc with an inner wheel disc after being matched with the inner wheel disc of a second wheel, can complete mounting by only one person, and greatly shortens the mounting time. In order to achieve the above purpose, the present invention adopts the following technical scheme: A wheel disc mounting tool of a package machine comprises a tool base and a plurality of positioning frames connected with the butt joint side face of the tool base and extending in the vertical direction, wherein the positioning frames are circumferentially arranged, temporary connecting portions are arranged at the extending end portions of the positioning frames, each positioning frame comprises a plurality of first positioning frames with short extending lengths and a plurality of second positioning frames with long extending lengths, and the first positioning frames and the second positioning frames are continuously arranged. In the present invention, "continuously arranged" refers to that the first positioning frames are adjacently arranged without inserting the second positioning frames, and the second positioning frames are adjacently arranged without inserting the first positioning frames, for example: the first positioning frame is denoted as A, the second positioning frame is denoted as B, the arrangement of A-A-A-B-B-B is called that A and B are respectively arranged continuously, and the arrangement of A-A-B-A-B-B is arranged discontinuously. Further, the tool base comprises an installation frame of an annular structure and a through hole formed by surrounding the installation frame, and the outer side edge of the installation frame is provided with an avoidance hole which is recessed radially towards the direction of the through hole. Further, the locating frames comprise three first locating frames and four second locating frames, and the avoidance openings are arranged between the first locating frames or between the first locating frames and the second locating frames. Further, an included angle formed by connecting lines of two directly adjacent locating frames and the axle center of the tool base is 45 degrees, and an included angle formed by connecting lines of two adjacent locating frames crossing the avoidance port and
