Bottom sealing and heating mechanism for pipe-in-pipe filling bottle

Abstract

The invention discloses a bottom sealing and heating mechanism for a pipe-in-pipe filling bottle. The bottom sealing and heating mechanism comprises a fixing frame, a steam and liquid introducing base, a heating tank, a detachable pipe-in-pipe heating assembly and a cooling assembly, wherein the pipe-in-pipe heating assembly is installed in the steam and liquid introducing base from bottom to top and is sequentially sleeved with a steam distribution disk, a flow distribution base, a limiting sleeve and an outer-layer pipe heating sleeve from inside to outside; a center hole is formed in each of the steam distribution disk and the flow distribution base; and the flow distribution base, the steam distribution disk and the heating tank are fixedly connected in a bolted manner after the base is sleeved with a locking stud. According to the mechanism, the inner wall of an outer-layer pipe and the outer wall and the inner wall of an inner-layer pipe at the tail of the filling bottle are heated and hot-melted in a mode of filling hot steam and circulating a cooling liquid, and the outer wall of the outer-layer pipe is cooled by circulating the cooling liquid, so that the outer wall of the tail of the filling bottle is kept at low temperature without deformation; and the inner wall of the outer-layer pipe and the outer wall of the inner-layer pipe are bonded under the clamping of a clamping mechanism at the next station, and the inner wall of the inner-layer pipe is hot-melted and bonded, so that the requirement of keeping the outer wall of the outer-layer pipe in good appearance is met, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of filling equipment, in particular to a bottom-sealing heating mechanism for tube-in-tube filling bottles. Background technique [0002] With the surge in the types and demand of modern daily cosmetics, skin care products, shampoos, shower gels and other products, the efficiency of traditional filling production lines needs to be further improved. Bottles and cans are generally used when filling liquids. Automatic equipment for automatic filling. Among them, filling bottles similar to facial cleanser and skin care products need to heat and micro-melt the tail of the bottle and automatically bond and package it. [0003] At present, filling bottles with a "pipe-in-pipe" structure have appeared on the market. Different emulsions are filled in the inner and outer layers, and are co-extruded from the bottle cap end for mixed use. There are few automatic bottom-sealing equipment for the filling bottle with thi...

Problems solved by technology

[0004] Purpose of the present invention: to solve the technical problem of automatically heating and melting the tail of the tube-in-tube filling bottle in the existing market, so as to facilitate the clamping and bonding of the latter station to realize the bottom sealing, and to meet the requirement that no residue is left on the outer wall of the outer tube Hot-melt traces and hot-melt deformation, the need to maintain a good appearance, we design a tube-in-tube filling bottle bottom cover heating mechanism, using the method of pouring hot steam and circulating cooling liquid, to heat the outer tube at the end of the filling bottle The inner wall of the inner tube, the outer wall of the inner tube and the inner wall are hot-melted, and the outer wall of the outer tube is cooled by circulating coolant, so that the outer wall of the tail of the filling bottle remains low temperature without deformation, and the inner wall of the outer tube and the outer wall of the inner tube are in the rear One-station clamping mechanism clamps and bonds, and the inner wall of the inner tube is hot-melt bonded, which fully meets the technical requirements in the background technology, and is practical and convenient
