Problems solved by technology

[0004] Although the combined glue delivery of two gear pumps can also achieve the effect of two-liquid sizing, the use of gear pumps in the prior art to deliver glue containing filler components (or glue with high viscosity or high concentration) will cause problems. The following problems: First, the glue with a certain hardness of the filler component, the glue with high viscosity or the glue with high concentration will affect the meshing of the driving wheel and the driven wheel when filling the space of the gear, making it difficult for the glue to be discharged from the meshing of the two teeth , and when the liquid has particles, it is very easy to cause wear to the gears, and it cannot be used in any situation. It is difficult to accurately control the accuracy and consistency of the glue, and it will reduce the service life of the sizing machine, especially the gear pump.
Second, the pressure at the outlet of the gear pump depends entirely on the resistance of the external continuous glue discharge system. The resistance is inversely proportional to the glue output. The influence of glue viscosity will produce a certain resistance, and the pump will have different backflow due to the size of the resistance, making it difficult for the gear pump to maintain its continuity and effectiveness, thereby reducing the production efficiency of the sizing industry
[0005] It can be seen that since the combination of two gear pumps is used to send glue with ordinary components and glue with filler components, the continuity of glue delivery will be affected. Glue is released in a fixed ratio or discontinuously, which affects the working efficiency of sizing
Moreover, at present, there is no good treatment method for glue containing fillers in China. Even if there is, it is necessary to use expensive foreign accessories to sizing glue containing fillers, resulting in the end user of the automatic sizing machine having to bear relatively high equipment. price, thereby increasing the production cost of the industry

Embodiment 1

[0028] In this embodiment, motors are used as an example for the driving device 1 and the driving device 2 to describe the following.

[0029] The structural representation of the glue delivery system of the double-liquid automatic sizing machine of the present invention is as follows: figure 1 As shown, the glue delivery system includes a system fixing plate 26, a controller 27, and an automatic glue pumping system for delivering glue containing filler components (or glue with high viscosity or glue with high concentration) and using an electric reciprocating pump. Automatic glue pumping system 2 of gear pump 1; among them, automatic glue pumping system 1 and automatic glue pumping system 2 are equipped with glue outlet and glue inlet, and automatic glue pumping system 1 and automatic glue pumping system 2 pass motor 1 respectively 8 and motor two 7 are connected with controller 27. The first motor 8 and the second motor 7 are fixed on the system fixing plate 26 through the ...

Embodiment 2

[0041] The only difference between this embodiment and Embodiment 1 is that the sliding device in the automatic glue pumping system 1 does not include sliding guide rails and sliders, but only includes the screw device fixed on the system fixing plate and the connecting block connected with the connecting rod .

[0042] The electric reciprocating pump in this embodiment and its connected connecting rod are located on one side of the connecting block. And the screw mandrel device is then made up of screw mandrel, screw mandrel nut and screw mandrel holder (screw mandrel head holder and screw mandrel head fixed tailstock). Wherein, the two ends of the screw rod are installed on the system fixing plate through the screw head fixing seat and the screw head fixing tailstock, and one end thereof is connected with the motor one through the coupling one to realize the rotary motion of the screw rod. The connecting block is connected with the screw nut, and the screw device drives the...

Abstract

The invention provides a double-liquid automatic sizing machine glue delivery system with high glue delivery precision, high cost performance and improved work efficiency. The system includes a controller and automatic glue pump system 1 and automatic glue pump system 2 connected with the controller. ; It is characterized in that: automatic glue pumping system 1 refers to automatic glue pumping system 1 using an electric reciprocating pump, and automatic glue pumping system 2 refers to automatic glue pumping system 2 using a gear pump. The double-liquid automatic sizing machine glue delivery system of the present invention can effectively solve the problem of feasibility and continuity of glue delivery for component glue containing fillers (or glue with high viscosity or high concentration glue), and realize the glue delivery system The two-component glue can be automatically delivered according to the required ratio, thereby reducing the cost of glue in various industries. The glue delivery system of the present invention can make domestic manufacturers of double-liquid glue sizers get rid of dependence on imported accessories, and can also greatly promote the development of the industry.

Description

technical field [0001] The invention relates to the technical field of automatic glue sizing machines, and more specifically, relates to a glue feeding system for a double-liquid automatic glue sizing machine. Background technique [0002] Automatic sizing machine is a key equipment in the production of semiconductor lighting (LED), home appliances, automobiles, electronics and other industries. In particular, semiconductor lighting (LED) is an environmentally friendly and energy-saving product vigorously promoted by the country, and its market and application prospects are very broad. The working principle of the glue delivery system of the automatic glue sizing machine is to automatically pump the two components of glue (the glue of the A component and the glue of the B component) from the glue inlet to the glue outlet according to the set ratio. The intersection of the intersection is fully mixed before sizing the workpiece. Therefore, the automatic glue output ratio of...
