the driving gear is movably arranged on the seat frame through a driving shaft at the center and is positioned below the same side of the U-shaped opening cavity gear;

the two transmission gears comprise a large transmission gear and a small transmission gear, the large transmission gear is arranged on the seat frame through a large rotating shaft and is in meshed transmission with the U-shaped cavity gear and the driving gear respectively; the small transmission gear is arranged on the seat frame through a small rotating shaft and is in meshed transmission with the U-shaped cavity gear and the driving gear respectively.

The outer side surface of the U-shaped cavity gear can be movably provided with a packaging belt turntable through a cylindrical pin rivet.

Compared with the prior art, the utility model has the advantages of it is following:

the utility model relates to a winding packing belt gear mechanism, which innovatively designs a U-shaped cavity gear and a driving gear to drive two transmission gears to rotate simultaneously, the two transmission gears are matched with each other to relay and drive the U-shaped cavity gear to rotate around an object at the center of a cavity, thereby achieving the beneficial effect of continuous winding; the device has the advantages of simple structure, low cost and high efficiency, and solves the problem that the mechanical arm cannot continuously surround.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

The specific embodiment is as follows:

in this embodiment, as shown in fig. 1, 2, 3, a winding and packaging gear mechanism includes a U-shaped cavity gear, a driving gear 8, two transmission gears, and a seat frame 9;

the U-shaped cavity gear is arranged as an arc gear 1 with a U-shaped opening cavity 11, and one side surface of the U-shaped cavity gear 1 is fixedly provided with an arc convex guide rail 2 which is concentric with the arc gear 1 and is circular along the arc gear 1;

a U-shaped opening cavity 11 with the same size as the U-shaped opening cavity 11 of the U-shaped cavity gear is fixedly arranged at the upper part of the seat frame 9, a circular arc concave sliding groove 10 matched with the circular arc convex guide rail 2 of the U-shaped cavity gear is fixedly arranged on one side surface of the seat frame 9, and the circular arc convex guide rail 2 is just clamped in the circular arc concave sliding groove 10 to rotate, so that the circle center part of the U-shaped opening cavity 11 is always kept in a cavity state;

the driving gear 8 is movably arranged on the seat frame 9 through a central driving shaft 7, is positioned below the same side of the U-shaped open cavity gear, and is not meshed with the U-shaped open cavity gear;

the two transmission gears comprise a large transmission gear 5 and a small transmission gear 14, the large transmission gear 5 is arranged on the seat frame 9 through a large rotating shaft 6 and is respectively meshed with the U-shaped cavity gear and the driving gear 8 for transmission; the small transmission gear 14 is arranged on the seat frame 9 through a small rotating shaft 15 and is in meshed transmission with the U-shaped cavity gear and the driving gear 8 respectively.

In this embodiment, as shown in fig. 1, 2 and 3, the outer side surface of the U-shaped cavity gear is movably provided with a wrapping tape rotating disc 4 through a cylindrical pin rivet 3.

Technical characteristics and working principle:

as shown in fig. 1, in a static state, the U-shaped open cavity 11 of the U-shaped cavity gear is completely overlapped with the U-shaped open cavity 11 of the seat frame 9, the opening faces to the right at the same time, an overlapping opening is formed, and a product or an object 12 to be wrapped and packaged is put in;

furthermore, a packaging belt turntable 4 is movably arranged on the outer side surface of the U-shaped cavity gear through a cylindrical pin rivet 3, one end of a winding belt 13 on the packaging belt turntable 4 is pulled out and wound on the product or object 12 for two circles, and the belt head is pressed;
