Problems solved by technology

Since the cup body generally moves forward in a step-by-step manner in the linear filling process, the cover film will inevitably move relative to the cup body under its own inertia during the process of the cup body from rest to motion and then to rest, resulting in deviation from the set position, the cover film deviat

Abstract

The invention discloses a suction cup, a film adding device and a filling production line, and belongs to the technical field of filling equipment, the suction cup comprises a shell, an inner pipe and a spring, the rear end of the shell is provided with a ventilation cavity, the inner pipe is provided with an air channel, the suction cup further comprises a suction nozzle, a vacuum breaking piece and a shaping disc, and the front end of the inner pipe is provided with a concave cavity; the suction nozzle and the vacuum breaking piece are arranged in the concave cavity, the suction nozzle is sleeved with the vacuum breaking piece, the suction nozzle is provided with an air hole, the shaping disc is arranged outside the front end of the inner pipe in a sleeving mode and partially extends forwards out of the inner pipe, and when the suction cup places the membrane at the cup opening, the edge of the membrane is bent downwards and deforms under the shaping effect of the shaping disc. The film adding device comprises the suction cup, and the filling production line comprises the film adding device. The reshaping disc is used for pre-reshaping the membrane, so that the edge of the membrane is bent and deformed to buckle a cup opening, the membrane can synchronously move forwards along with a cup body, the membrane is located at a set position after heat sealing and reshaping, the appearance attractiveness of a product is improved, and the heat sealing effect of the product is also improved.

Description

Technical field [0001] The present invention relates to the technical field of filling equipment, in particular to a suction cup, the present invention further relates to a filming device using such suction cups, further, the present invention further relates to a filling production line using such a filming device. Background [0002] In the field of filling technology, some products in the cup body after filling the material will use aluminum cap film for sealing treatment, the sealing treatment in the prior art based on the linear filling process generally includes adding cap film, heat sealing, shaping three steps. In the step of installing the lid film, the general use of rolling mounting structure to place the lid film on the cup body, for example, the invention application for announcement number CN111153209A discloses a rotary conveyor device, in the technical scheme, the suction cup is only responsible for absorbing the lid film, the operation function of the entire rota...
