Description

TECHNICAL FIELD

[0001] The utility model relates to a locking device, especially to a barrel hoop automatic locking device for packaging barrels in a barrel production line, and belongs to the barrel packaging field. BACKGROUND

[0002] In the packaging of products, for safety, toxic products such as cyanide and arsenic are packaged in barrels. In actual production lines, unmanned workshops are generally used, but in the packaging production line, manual weighing and manual operation are still used. Although appropriate protective measures are taken in production, it is still difficult to avoid chronic poisoning of workers, which will cause different degrees of harm to workers' bodies over a long period of time. In order to avoid poisoning incidents, most countries have stopped the production of toxic products by manual packaging. In order to ensure the smooth operation of the production line, automatic unmanned production lines are now used for packaging toxic products.

[0003] In the packaging of products, especially in the packaging of toxic products such as cyanide, there are two kinds of packaging. One is to use a ton box (a packaging box that can hold one ton of weight), and the other is to use a round barrel. In the round barrel packaging production line, empty barrels are conveyed by a conveying line. In the production line, plastic packaging bags are first placed in the round barrels, and then the specified weight of toxic products is added to the plastic packaging bags. In order to prevent the leakage of toxic products, a plastic sealing machine is used to heat seal the opening, and then a barrel hoop 47 with a locking handle is used to lock the barrel cover 14 and the barrel opening. Figure 6 The barrel hoop is a planar structure. The barrel hoop 48 is provided with a rotatable locking handle 49. The locking handle 49 is hinged to the barrel hoop 47 through hinge shaft one 16a, hinge shaft two 16b, hinge shaft three 16c, and a connecting rod. The inner periphery of the barrel hoop 48 and the locking handle 49 is provided with a groove. The barrel hoop 48 is locked with the top cover 14 and the upper periphery of the packaging barrel in the groove. After the locking handle 49 is locked, the inner periphery groove of the locking handle 49 is superimposed on the outer periphery of the barrel hoop 48. The barrel hoop 48 and the locking handle 49 are respectively provided with barrel hoop insertion holes 15b and handle insertion holes 15a corresponding to each other.
