Description

TECHNICAL FIELD

[0001] The application relates to the technical field of bottle mouth sealing, in particular to a bottle mouth film coating device special for large barrels. BACKGROUND

[0002] In order to ensure the safety and hygiene of food, some barrels containing food are usually sealed with lids to prevent the food in the barrels from being in contact with air and being deteriorated or oxidized. For some food which is not sensitive, the food can be stored by setting a screw thread or a hard seal at the barrel mouth, and for food such as sugar or biscuits which is easy to be deteriorated by moisture, film coating sealing needs to be performed at the barrel mouth.

[0003] At present, a film coating sealing device usually uses a heat sealing mode, that is, a barrel or a bottle to be sealed is moved to below the film coating device along a conveying belt, and then a heat sealing device in the film coating device moves downward, so that the film is in abutment with the barrel mouth or the bottle mouth, and the film is fused and fixed to the opening of the barrel by heating.

[0004] According to the related technology, the inventor considers that after the conventional sealing device seals the barrel mouth, the film is separated from the film coating device by heat melting, and in the process of separating the film, the film coating which has been adhered to the bottle mouth is easily torn off, which increases the waste rate and causes waste of the film coating. CONTENT OF THE UTILITY MODEL

[0005] In order to reduce the possibility of the film coating being torn off in the separating process and improve the film coating yield, the application provides a bottle mouth film coating device special for large barrels.

[0006] The bottle mouth film coating device special for large barrels provided by the application adopts the following technical scheme:

[0007] The bottle mouth film coating device special for large barrels comprises a support frame and a film coating assembly, the film coating assembly is arranged on the support frame, the film coating assembly comprises an upper connecting plate, a heating block, a heating plate and a cutting ring, the upper connecting plate is slidingly arranged on the support frame, a first driving member for driving the upper connecting plate to move in the vertical direction is arranged on the support frame, the heating block is arranged on the bottom surface of the upper connecting plate, the heating plate is arranged on the bottom surface of the heating block, a heating ring table is arranged on the bottom surface of the heating plate, the cutting ring is arranged on the bottom surface of the upper connecting plate, the cutting ring is coaxially arranged outside the heating plate, cutting teeth are arranged on the bottom edge of the cutting ring in the circumferential direction, and the height of the bottom edge of the cutting ring is lower than the height of the heating ring table.

[0008] By adopting the technical scheme, the barrel body is placed below the film covering assembly. The film is arranged below the cutting ring. When the film is covered, the upper connecting plate moves downward under the driving action of the first driving member. The heating ring table contacts the film at the edge of the barrel body and performs hot pressing. The cutting ring descends with the upper connecting plate and cuts off the film covering the opening of the barrel body. Through the cooperation of the support frame and the film covering assembly, hot pressing and cutting and separation of the film covering the opening of the barrel body are realized, which reduces the possibility that the film covering the bottle opening is peeled off during the separation process and improves the film product rate.
