Abstract

The invention relates to the technical field of injection pumps, and particularly discloses a dosing system. The dosing system comprises a liquid storage bin, a first heating assembly, a flow channel, an injection valve body and a second heating assembly, wherein the first heating assembly is arranged outside the liquid storage bin in a sleeve mode, a nozzle is arranged on the injection valve body and connected to an opening in the other end of the flow channel, openings are formed in the two ends of the flow channel correspondingly, the opening in one end of the flow channel communicates with the liquid storage bin, the opening in the other end of the flow channel is connected to the nozzle, the flow channel further comprises a closing element, the second heating assembly is slidably arranged outside the flow channel and the nozzle in a sleeve mode. According to the dosing system, the liquid storage bin and the nozzle of the dosing system can be heated separately, the second heating assembly is directly arranged on the flow channel in a sliding and sleeve mode, the flow channel and the nozzle are directly heated, assembly and disassembly are convenient, the heating effect is good, temperature control is more accurate, and the temperature difference between a to-be-dosed medium and the nozzle can be reduced, so that the dosing accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of jet pumps, in particular to a dosing system. Background technique [0002] In the dosing system, the dosing medium is required to be in a liquid state. When the dosing medium is viscous or even close to a solid state, it needs a temperature higher than room temperature to change it into a liquid state. The usual practice is to add a heating element to the storage part of the dosing system, and heat the dosing medium to turn it into a liquid before it is sprayed out. In addition, the temperature of the dosing medium is precisely controlled, and the temperature of the dosing medium is evenly distributed, so the dosing effect will be more accurate. [0003] At this stage, most of the dosing systems use hot-melt glue injection valves, but the existing hot-melt glue injection valves have complex structures on the one hand, and there are temperature differences between the liquid storage tank, flow channel and...
