Description

Tunnel type sealing assembly and sealing machine

Technical Field

The utility model belongs to the technical field of the sealing equipment, concretely relates to tunnel type seals subassembly and capper.

Background

The sealing machine is a device widely applied to the product sealing link in the production industries of medicine, food, chemical industry and the like, and is used for achieving the purpose of sealing and isolating a packaging container from the external environment; the aluminum foil sealing device utilizes the principle of electromagnetic induction to generate an eddy current magnetic field in the aluminum foil to generate heat, namely, the aluminum foil covered on the opening (bottleneck) of the packaging container generates high heat, so that the plastic film compounded on the surface of the aluminum foil is melted and fused with the bottleneck of the packaging container, and the sealing function is further realized. However, the sealing machine in the prior art has certain inconvenience in use for sealing the special-shaped bottle cap; specifically, in the traditional mode, an aluminum foil for sealing is cut into a gasket matched with a bottle cap in advance and is filled into the bottle cap, then the bottle cap is screwed on a bottle mouth, so that an aluminum foil sealing film is pressed on the bottle mouth, and finally the aluminum foil sealing film is fused with the bottle mouth through a sealing machine; the surface of the traditional bottle cap is planar, so that a sealing assembly in the sealing machine can be easily attached to the surface of the bottle cap and heat the aluminum foil sealing film. For example, in order to facilitate lifting, the top of some packaging containers is equipped with a handle, the bottle mouth of the packaging container is located on one side of the handle, and the height of the handle is often higher than that of the bottle mouth, so that in the prior art, a rotary packaging mechanism is generally used for the packaging container of this kind to drive a sealing head to package the packaging container, and the rotary packaging mechanism is relatively complex in composition and relatively high in cost.

For another example, a bottle cap with a slender nozzle is used for bottled tomato sauce, so that a user can squeeze the tomato sauce onto food conveniently; at this time, the sealing cannot be effectively performed by using the conventional sealing machine, that is, the electromagnetic coil in the sealing head cannot be effectively close to the aluminum foil sealing film. At this time, the containers requiring the use of the shaped bottle cap are mainly treated in the following two ways: 1. for the packaging of the container, the traditional plane bottle cap is still used for packaging, and the special-shaped bottle cap is taken as an accessory to be delivered along with the container, namely, when the medium in the container is used, the aluminum foil sealing film is removed and then the attached special-shaped bottle cap is independently replaced; 2. the sealing film is independently used for sealing the container, and finally the special-shaped bottle cap is screwed on. Wherein, the first sealing mode needs to be provided with a bottle cap independently, thereby increasing the production cost of enterprises; the second sealing method not only increases the sealing process, but also increases the production cost of enterprises, and further causes the sealing machine to have the problem of inconvenient use.
