Description

Technical Field

[0001] The invention relates to high-low pressure switching glue spraying equipment, belonging to the technical field of glue injection. Background Art

[0002] Gluing equipment is a device that applies or drips glue with sticky effect on product parts. The existing process is that the pressure plate pump sends A and B glues into the static mixer through the oil pipe to form a 1:1 two-component glue, and then enters the screw pump through the one-way ball valve. The hydraulic motor squeezes the two-component silicone into the storage position, and the hydraulic motor of the plunger pump presses the glue into the piston rod. The glue discharge and sealing of the glue injection head are achieved by controlling the air path. However, the traditional glue injection machine's oil cylinder hydraulic glue supply system has a variety of hydraulic cylinder supporting equipment, and the pressure control accuracy is not high. It is impossible to ensure that the AB glue is mixed in proportion. Parameters in all aspects are uncontrollable, and thus the glue discharge quality is uncontrollable. Summary of the invention

A glue injection pneumatic ball valve is provided between the mixer and the storage cylinder. The glue inlet pneumatic valve is used to control whether the mixed glue liquid can enter the storage cylinder. The single-component supply device is a pair. The two single-component supply devices supply different glue liquids, which have viscosity after mixing. They are connected to the static double-liquid valve through pipelines respectively. The static double-liquid valve is a prior art and can input the glue liquid in the two single-component supply devices into the mixer at the rear in proportion. The single-component supply device includes a support frame, a one-way supply plunger pump, a supply motor and a temporary storage cylinder. The supply motor is fixed on the support frame, and the one-way supply plunger pump is installed on the supply motor. One end of the one-way supply plunger pump is connected to the temporary storage cylinder. The single-component supply device is used to stably supply the single-component glue liquid to the static double-liquid valve.

[0005] Preferably, in order to better observe the parameters and intuitively display the parameter values, a single-component glue discharge pressure gauge is provided between the temporary storage cylinder and the static double-liquid valve, a glue inlet pipeline is provided on the upper surface of the temporary storage cylinder, and a single-component glue inlet pressure gauge and a glue inlet pneumatic ball valve are installed on the glue inlet pipeline.

The necessary encoder and controller for driving the servo motor need to be provided externally to control the feed rate of the plunger pump, thereby realizing the switching of high and low pressures. The driving motor 1031 is installed on the glue injection plunger pump 1032. When in use, the driving motor 1031 drives the glue injection plunger pump 1032 to move up and down, thereby squeezing the glue into the glue injection head 101. The mixer 2 is a 24-section static mixing tube. The mixer 2 is used to mix the glue of the two components evenly so as to supply it to the glue injection mechanism 1 for use. A glue injection pneumatic ball valve 5 is provided between the mixer 2 and the storage cylinder 102. The glue inlet pneumatic valve is used to control whether the mixed glue can enter the storage cylinder 102.

[0017] When in use, the static double-liquid valve 3 delivers the single-component glue liquid to the mixer 2 in proportion, and then the glue injection pneumatic ball valve 5 on the mixer 2 is opened to allow the glue liquid to enter the storage cylinder 102. The single-component supply device 4 is a pair, and the two single-component supply devices 4 supply different glue liquids, which can become usable glue liquids after mixing. They are respectively connected to the static double-liquid valve 3 through pipelines. The static double-liquid valve 3 is a prior art and can input the glue liquid in the two single-component supply devices 4 in proportion to the mixer 2 at the rear.

The external pressure plate pump provides glue to the voltage stabilizer 8, and then the voltage stabilizer 8 provides stable glue to the one-way supply plunger pump 402 on the support frame 401 through the glue inlet pipe.

[0020] When the present invention is in use, first the power connector is connected to the external power supply, and then the external pressure plate pump provides the glue liquid to the voltage stabilizer 8, and then the voltage stabilizer 8 provides the stable glue liquid to the one-way supply plunger pump 402 on the support frame 401 through the glue inlet pipe, and the supply motor 403 can drive the one-way supply plunger pump 402, and then the glue liquid is transported unidirectionally, and the single-component supply device 4 is used to stably supply the single-component glue liquid to the static double-liquid valve 3.
