Embodiment Construction

[0029] In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] like image 3 and Figure 4 As shown, the present invention provides an ultrasonic sealing device, comprising a welding head 3 and an anvil 4, the front ends of the welding head 3 and the anvil 4 respectively have sealing surfaces, and the sealing surfaces are used to overlap two or more lamellae. The packaging material 10 is clamped, and the thermoplastic resin of the packaging material is melted by ultrasonic waves, so as to seal the packaging material; the welding head 3 and / or the anvil 4 have more than four sealing surfaces. In the present invention, by setting more than four sealing surfaces on the welding head 3 and / or the anvil 4, the sealing pressure per unit area can be effectively improved without changing the clamping pres...

Abstract

The invention discloses an ultrasonic sealing device and a filling machine. The ultrasonic sealing device comprises a welding head and an anvil block, wherein the front end of the welding head and thefront end of the anvil block are each provided with a sealing face, the sealing faces are used for clamping a packaging material overlapped with two or more sheet layers, thermoplastic resin of the packaging material is melted through ultrasonic waves, and therefore the packaging material is sealed; and more than four sealing faces are arranged on the welding head and / or the anvil block. According to the ultrasonic sealing device, the welding head and / or the anvil block are / is provided with the four or more sealing faces, the sealing pressure per unit area can be effectively improved under the condition that the clamping pressure and other settings of an existing ultrasonic sealing device are not changed, and therefore the sealing reliability is improved, and the problems of missing sealing and poor sealing are effectively reduced.

Description

technical field [0001] The invention relates to the field of filling and sealing, in particular to an ultrasonic sealing device and a filling machine. Background technique [0002] Liquid paper containers are widely used for storing liquid beverages such as fruit juice, tea, coffee, milk beverages, and soups, and alcoholic beverages such as Japanese sake and shochu. The liquid paper container has shapes such as a roof type, a square brick type, or a cylindrical type. [0003] For example, as figure 1 As shown, for a square brick type container, a longitudinal seal is affixed to the longitudinal edge of the packaging material 10 having a thermoplastic resin layer on the surface, the packaging material 10 is formed into a cylindrical shape, and the longitudinal edges of the packaging material 10 are overlapped and sealed, thereby It is formed into a packaging material cylinder 11, and then the packaging material cylinder 11 is filled with the contents, and the end of the pac...
