Description

Technical Field

[0001] The utility model belongs to the field of packaging machinery, and in particular relates to a double-support rotary box suction head. Background Art

[0002] In the field of packaging, a rotating suction box head is needed to grab and paginate cartons and paper sheets. The currently used rotating suction box head adopts a rotating shaft supported on one side. The rotation of the rotating shaft drives the rotating rod to rotate, and the suction cup assembly arranged on the rotating rod grabs and paginates cartons or paper sheets. For cartons or paper sheets with longer lengths, a longer rotating rod is required to arrange more suction cup assemblies. However, the lengthening of the rotating rod will increase the inertia of the rotating rod after rotation, and the end of the rotating rod away from the support point will sag due to its own weight, causing increased wear between the rotating shaft and the bearing. Moreover, the rotation of the rotating shaft needs to be driven by a synchronous belt, so a longer rotating rod requires greater power, which also increases the wear on the synchronous belt.

[0005] A support plate for mounting a gear set and a rotating rod is respectively arranged at both ends of the rotating suction box assembly, the driving gear is rotatably mounted at the center position of the outer side of the support plate, the rotating rod is located between the two support plates, and both ends of the rotating rod are rotatably supported on the support plates; the support plate is fixed on the inner side of the fixed plate.

[0011] The beneficial effects of the utility model are as follows: the utility model adopts the form of two-end support, and can adopt a rotating rod of a larger length.

[0019] The specific structure of the rotating suction box assembly can be referred to Figure 2 As shown, it includes two support plates 9, three rotating rods 7, a plurality of suction cup assemblies 8 arranged on the rotating rods 7, and a gear set arranged outside the support plates 9.

[0020] The two ends of the rotating rod 7 are rotatably supported on two supporting plates 9 respectively. The middle part of the rotating rod 7 is a square rod body with a rectangular cross section. A plurality of suction cup assemblies 8 are arranged at intervals on the square rod body.

[0021] The gear set is used to transmit the power of the rotating shaft 3 to each rotating rod 7, so as to realize the synchronous rotation of the three rotating rods 7. The gear set includes a driving gear 10 rotatably mounted at the center of the support plate 9, the driving gear 10 is fixedly connected to the rotating shaft 3, and the driving gear 10 is driven to rotate by the rotating shaft 3; the gear set also includes an intermediate gear 11 and a driven gear 12, the driven gear 12 is fixed to the end of the rotating rod 7, each driven gear 12 is connected to the driving gear 10 through the intermediate gear 11, the intermediate gear 11 is rotatably mounted on one side of the driven gear 12 matched therewith, and the intermediate gear 11 is meshed with the driving gear 10 and the driven gear 12 for transmission.
