Embodiment Construction

[0031] In order to clearly illustrate the technical features of the solution, the solution will be described below through specific implementation modes.

[0032] When the punched and stretched blank enters the stretching machine, start the stretching machine. Within a period of time after the stretching machine is started, the temperature of the stretching die will gradually increase from low to the specified temperature. , the height of the thinned and stretched cans cannot reach the qualified height, so it is necessary to remove the unqualified cans, usually by manual removal. Therefore, when manually picking up, it will touch the subsequent qualified cans, causing the subsequent cans to deform and produce unqualified products. Based on the above problems, the technical solution of the present invention is further adopted.

[0033] see figure 1 as well as figure 2 , the present invention is a rejecting device applied to the slideway of a can stretching machine, comprisi...

Abstract

The invention provides a rejecting device applied to a slideway of a pop can stretching machine, belonging to the technical field of pop can production. The technical solution is: including slideway 1 and slideway 2 fixedly connected with slideway 1, a retaining bar is fixed between slideway 2 and slideway 1, and the retaining strips are arranged on both sides of slideway 1 and slideway 2. One side of the retaining bar includes an upper half and a lower half, an interval is provided between the upper half and the lower half, and a rejecting mechanism is provided at the interval, and the rejecting mechanism includes a bottom plate, a bracket one and a bracket two, and An opening and closing mechanism is arranged between the second and the support one, and the opening and closing mechanism drives the support two and the support one to move in the opposite direction, and a suction cup mechanism is also arranged on the bottom plate, and the suction cup mechanism translates the can to the support one and the support two. The beneficial effects of the present invention are: the present invention removes the unqualified pop cans on the slideway at the same time through the suction cup, the work efficiency is fast, and the pop cans will not collide with the subsequent pop cans when they are removed, effectively ensuring the quality of the subsequent pop cans.

Description

technical field [0001] The invention relates to the technical field of pop can production, in particular to a rejecting device applied to a slideway of a stretching machine for pop cans. Background technique [0002] Aluminum two-piece cans are a kind of packaging that is popular with consumers and are widely used in beverage, beer and other industries. [0003] The production process of pop cans is relatively complicated, mainly composed of stamping, metal surface treatment, printing, online inspection, packaging and other processes. After punching and stretching, the thin aluminum plate is punched into a round billet, and then stretched into a cup-shaped blank for the thinning and stretching process. The thinning and stretching process is a composite stamping process with a blanking edge. It consists of 1 ordinary stretching, 3 thinning stretches and 1 bottom reverse stretching process. In one stamping stroke, the blank is punched into a thin-walled cylindrical workpiece ...
