Description

Technical Field

[0001] This utility model relates to the technical field of glue dispensing equipment, specifically a two-component glue quantitative dispensing machine. Background Technology

[0002] A two-component dispensing machine is a device that can dispense two types of adhesives from large packages into small syringes. By applying pressure in an appropriate manner, it can process and dispense low to medium viscosity adhesives containing certain fillers, such as epoxy resin, polyurethane, and silicone. Existing two-component dispensing machines mostly use pneumatic dispensing devices, which result in large fluctuations in dispensing pressure, leading to uneven dispensing flow and directly affecting the subsequent quantitative accuracy. Moreover, the current quantitative structure of two-component syringes is a fixed ratio structure, which cannot meet the adjustment needs of different ratio ranges. Utility Model Content

[0003] The purpose of this invention is to provide a two-component adhesive quantitative dispensing machine to solve the technical problems in the background art.

A second glue inlet is provided on the first metering pump and connected to it. A glue supply port on the first metering pump is connected to a first metering glue injection mechanism through a pipe for glue material transportation.

[0007] The first quantitative dispensing mechanism includes a first dispensing cylinder, a first adjusting screw, a first adjusting nut, and a first dispensing valve.

[0009] The compression device includes a second mounting plate. From top to bottom, the second mounting plate comprises a first compression cylinder, a second compression cylinder, a compression drive plate, a pressure column, and a second positioning component for positioning the rubber cartridge. The first compression cylinder is fixed to the second mounting plate. A first slide with a frame structure is mounted below the drive shaft of the first compression cylinder. The first slide is slidably connected to the second mounting plate. The first compression cylinder drives the first slide to slide up and down.

During the downward movement of the pressure plate, continuous pressure is applied to force the adhesive from the bottom inlet to the first metering pump and then flow into the dispensing device. The pressure plate and the metering pump achieve high-flow and precise metering dispensing, and the amount of adhesive residue at the bottom of the glue tank is small, avoiding adhesive waste. In addition, the dispensing device of this application is equipped with two sets of metering injection mechanisms.

Two sets of quantitative glue dispensing mechanisms with identical structures are provided on the top of the first mounting plate 6, namely the first quantitative glue dispensing mechanism 7 and the second quantitative glue dispensing mechanism 8. The first quantitative glue dispensing mechanism 7 and the second quantitative glue dispensing mechanism 8 are installed side by side on the first mounting plate 6. The first quantitative glue dispensing mechanism 7 and the second quantitative glue dispensing mechanism 8 are respectively connected to the first glue supply device 3 and the second glue supply device 4 through pipes. The first positioning component 9 for placing the glue cylinder is provided below the first quantitative glue dispensing mechanism 7. The first positioning component 9 is fixedly installed on the first mounting plate 6.

[0022] The first glue supply device 3 of this application includes a first material tank 301, two sets of first pressure plate 304 cylinders 302, a first metering motor 303, and a first pressure plate 304. The two sets of first pressure plate 304 cylinders 302 are installed vertically at the front and rear ends of the first material tank 301. The drive shafts of the two sets of first pressure plate 304 cylinders 302 are linked by a first horizontal plate 307. The first metering motor 303 is fixed on the first horizontal plate 307. The first pressure plate 304 slides up and down inside the first material tank. The first metering motor 303 is driven and installed below a first metering pump 306. The bottom end of the first metering pump 306 is installed and connected to the first pressure plate 304. A first glue inlet 304-1 is provided at the axial position of the first pressure plate 304, and a second glue inlet is provided on the first metering pump 306. 306-1 is connected to it. The first metering pump 306 is equipped with a glue inlet and is connected to the first metering glue dispensing mechanism 7 through a pipe for glue conveying. A sealing gasket 305 is installed on the outer side of the first pressure plate 304 near the material cylinder and is tightly fitted to the barrel wall. When performing glue dispensing operation, the bottom end face of the first pressure plate 304 is always in contact with the glue surface in the first material barrel 301 and is pressed against the glue surface. The first pressure plate 304, the sealing gasket 305 and the first material barrel 301 form a sealed space. Under the drive of the cylinder 302 of the first pressure plate 304, the glue in the first material barrel enters the first glue inlet 304-1. Under the drive of the first metering motor 303, the first metering pump 306 is rotated, and the glue in the first glue inlet 304-1 is transported to the first metering glue dispensing mechanism 7 through the pipe.

The outlet of the first dispensing valve 705 is connected to a first dispensing tube 706 for dispensing dispensing into the glue cylinder. The first sensing device 704 uses an existing magnetic sensor to monitor the position of the piston rod. When the piston rod in the first dispensing cylinder 701 moves, the first sensing device 704 senses the position of the piston rod in the cylinder. When it senses a specific set position, the first dispensing cylinder 701 retracts the piston rod, so that the material injected into the glue tube reaches the set value. When it is necessary to change the amount of material in the glue tube, it is only necessary to rotate the first adjusting screw 702 to adjust the position of the first sensing device 704. The second quantitative dispensing mechanism 8 has the same structure and working principle as the first quantitative dispensing mechanism 7, so it will not be described again. The dispensing amount of the first quantitative dispensing mechanism 7 and the second quantitative dispensing mechanism 8 can be adjusted according to the requirements.

When using it, the glue dispensing device 5 can transport the glue in the first glue supply device 3 and the second glue supply device 4 to the corresponding glue dispensing valve through the pipeline, and inject the glue into the empty glue cartridge through the two-component glue injection valve. After injection, the glue cartridge after injection is placed directly into the second positioning component 15 on the pressure plug device 10, and the pressure plug device 10 performs the sealing operation.
