Embodiment Construction

[0029] figure 1 The device in -3 is also known as an applicator head or a liquid dispensing device for dispensing or applying liquids such as adhesives, hot melt adhesives, cold glue, sealants, etc. to various bases. The device 1 comprises a metal base 2 and four dispensing or dispensing assemblies 4 , 6 , 8 , 10 each screwed onto the base 2 from which liquid flows out through at least one discharge opening 12 . The dispensing assembly 4-10 can also be supplied with compressed gas, which emerges through the compressed gas nozzle in the area of ​​the discharge opening 12 and acts on the fluid so as to spray or swirl the fluid. In the direction indicated by the arrow 14, the substrate to be coated passes the device 1 under the discharge opening and is transported by a conveyor, not shown in the figure. The device 1 can be mounted on a support structure by means of fastening screws 16 fastened on the base 2 .

Abstract

A method and device for delivering a fluid, in which the fluid is fed from a fluid source of a fluid-delivery device and delivered through a discharge orifice assigned to the delivery device. Before the fluid is delivered through the discharge orifice, it is heated or cooled by flowing through a heat-transfer chamber, which contains a fluid-permeable structure having a large number of communicating cavities through which the fluid flows.

Description

technical field [0001] The present invention relates to a method of dispensing fluid, wherein the fluid is provided from a fluid source of a fluid dispensing device and is dispensed through a discharge port connected to the dispensing device. [0002] The present invention relates to a fluid dispensing device having a fluid channel, wherein the channel communicates with a fluid source and opens to a discharge for dispensing fluid. Background technique [0003] In many industrial applications, a flowing substance (fluid) is dispensed and deposited or coated on a substrate with the aid of a fluid dispensing device. The fluid substance can be, for example, an adhesive, a paint or a sealing material, and the base can be a personal care product, a plastic board, furniture, a mechanical component, and the like. Depending on the application, for example, the fluid substance can be dispensed in the form of beads, strips or films, or the substance can be ejected with the aid of a ga...
