Double-component dispensing system

Abstract

The invention discloses a double-component dispensing system. The double-component dispensing system comprises a double-component screw pump, a mounting assembly, a refrigerating mechanism and a leakage stopping mechanism. The double-component screw pump comprises two container blocks, two glue pumping assemblies and a mixing pipe, wherein a mounting surface is arranged on one side of each container block, the two mounting surfaces are oppositely arranged and are detachably connected, a glue outlet flow channel of which the two ends communicate with each other is formed in each container block, each glue pumping assembly can be connected with any one of the container blocks so as to pump glue to the corresponding glue outlet flow channel, and one end of the mixing pipe communicates with the glue outlet flow channels of the two container blocks. The mounting assembly comprises a mounting support and a fastener. The refrigerating mechanism is arranged on one side of the mounting assembly, and at least one part of the mixing pipe is arranged in the refrigerating mechanism and is refrigerated by the refrigerating mechanism. The leakage stopping mechanism is arranged on one side of themounting assembly, and at least one part of the mixing pipe is arranged in the leakage stopping mechanism so that leakage of the mixing pipe is stopped by the leakage stopping mechanism. The double-component dispensing system has the advantages of simple structure, easiness in assembling and disassembling and the like.

Description

technical field [0001] The invention belongs to the technical field of automatic glue dispensing equipment, and in particular relates to a two-component glue dispensing system. Background technique [0002] Two-component dispensing is to continuously inject component A and component B into the static / dynamic mixing tube according to the required mixing ratio, and the mixed glue flows out from the end of the mixing tube and finally points out from the needle. In the two-component dispensing process, the more accurate the mixing ratio of component A and component B, the better the bonding performance of the mixed glue; The more consistent the bonding performance is. Based on the above-mentioned high-precision process application requirements, the self-sealing quantitative dispensing pump is made of high-quality stainless steel processed into an eccentric screw as the rotor and inert rubber into a double-helix chamber as the stator, which can ensure super high dispensing volum...

Problems solved by technology

Not only does it take a lot of time to disassemble, but it also requires replacement parts, resulting in poor interchangeability of this two-component

The existing two-component screw pump is a mirror image assembly method, which is divided into a left pump and a right pump. The relative positions of the left pump and the right pump are fixed, and the interchangeable installation of the left and right single pumps cannot be realized.

When the position of the two pumps needs to be adjusted during use, the relevant accessories need to be replaced to meet the requirements of use, and the adaptability of on-site installation is poor

The parts corresponding to the same position of the left pump and the right pump are left and right symmetrical parts, so two kinds of parts need to be manufactured during manufacturing, resulting in a multiplied number of parts

The existing two-component screw pump stator mounting holes and glue flow channel holes are distributed on different parts, resulting in a large number of parts in the existing two-component pump body, the overall length of the pump body is lengthened, and the assembly of the pump body is complicated. Does not meet the lean nature of product design

The existing two-component screw pumps share a double-pump assembly. Due to the large volume of the double-pump assembly, when cleaning the pump body, the required cleaning container is large and the amount of cleaning agent is large, resulting in inconvenient cleaning.

In the existing two-component screw pump, the pressure sensor is fixed on both sides, which directly increases the width of the screw pump, and the customer often has strict requirements on the width when using it on site.
