Description

Technical Field

[0001] The utility model relates to steel cylinder packaging equipment, in particular to an automatic pressing and covering mechanism suitable for small steel cylinder packaging cartons. Background Art

[0002] As a container for storing, transporting and using high- and low-pressure liquefied gases, a steel cylinder is mainly composed of a cylinder body, a cylinder valve and a handle. After the steel cylinder is produced, the cylinder body needs to be placed in a packaging box for individual packaging. In order to improve the protection of the steel cylinder and the cylinder handle, the packaging boxes for steel cylinders on the market currently have ear plates on the box cover. However, the previous steel cylinder packaging device cannot open the ear plates during the packaging process, which results in the need for manual opening of the ear plates, resulting in low overall work efficiency. Utility Model Content

The packaging carton includes a carton main body which is sleeved on the outside of the small steel cylinder. An opening is arranged on the top of the carton main body, and two hanging ears are symmetrically arranged in the opening. Two handles are symmetrically arranged on the top of the small steel cylinder, and the handles include a fixing part and a handle part connected to the fixing part. The carton positioning mechanism contacts the outer wall of the carton main body for positioning the carton main body. The steel cylinder positioning mechanism extends from the opening of the carton main body into the fixing parts of the handles on both sides of the small steel cylinder for positioning the small steel cylinder. The pressing cover mechanism includes two symmetrically arranged pressing plates and a pressing plate driving device. The pressing plate driving device drives the two pressing plates extending into the opening of the carton main body to move away from each other, so as to press the hanging ears of the packaging box into the handle part of the handle.

[0005] Furthermore, it also includes an integral lifting device, which is used to drive the carton positioning mechanism to descend to the side of the carton body, and drive the cylinder positioning mechanism and the capping mechanism to extend from the opening of the carton body into the interior of the carton body.

[0006] Further, the carton positioning mechanism includes a baffle mounting base, a plurality of carton positioning baffles, a plurality of baffle pressure wheels and a baffle pressure wheel driving member, the carton positioning baffle includes a mounting portion, a driving portion located at one end of the mounting portion and a positioning portion located at the other end of the mounting portion, the mounting portion extends vertically and is hinged on the baffle mounting base, the driving portion and the positioning portion extend obliquely away from the baffle mounting base, the baffle pressure wheel abuts against the upper side of the driving portion, the baffle pressure wheel driving member drives the baffle pressure wheel to move downward, the baffle pressure wheel drives the carton positioning baffle to rotate around the baffle mounting base, the positioning portions of the carton positioning baffles approach each other and abut against the carton body, so as to position the carton body. The positioning portion of the carton positioning baffle adopts an elastic sheet.

[0007] Furthermore, the cylinder positioning mechanism includes a positioning claw mounting seat, two symmetrically arranged positioning claws, and a positioning claw driving member. The two positioning claws are symmetrically hinged on the positioning claw mounting seat. The positioning claw driving member drives the positioning claw to rotate relative to the positioning claw mounting seat to achieve the approach and distance between the two positioning claw ends. When the two positioning claw ends are far away from each other, they press against the fixed parts of the handles on both sides of the small cylinder to achieve the positioning of the small cylinder.

[0008] Furthermore, the positioning claw driving member also includes a rotating motor, which is used to drive the positioning claw mounting seat to rotate around a rotating shaft in a vertical direction. When the two positioning claw ends are away from the fixing parts of the handles on both sides of the small steel cylinder, the rotating motor drives the positioning claw mounting seat to rotate, thereby driving the small steel cylinder to rotate through the positioning claw to adjust the angle of the small steel cylinder. An anti-slip component is provided at the end of the positioning claw that contacts the small steel cylinder.

[0009] Furthermore, the press-in insert is L-shaped, including a press-in portion perpendicular to the vertical direction and a connecting portion parallel to the vertical direction. The press-in portions of the two press-in inserts are away from each other, and the hanging ears of the packaging box are pressed into the handle portion of the handle.

[0010] Furthermore, the push-in plug plate driving device includes two symmetrically arranged telescopic cylinders, the driving ends of the telescopic cylinders are fixedly connected to the connecting parts of the push-in plug plates, and the telescopic movement of the two telescopic cylinders drives the connecting parts of the two push-in plug plates to move closer to or farther from each other.

[0011] Beneficial effect: Compared with the prior art, the utility model has the advantage that the cardboard on the carton used to clip the cylinder handle can be automatically pushed outward by pressing the plug plate, which changes the previous method in which the carton opening device cannot operate the cardboard and requires subsequent manual processing, thereby improving work efficiency.
