Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of glue dispensing components, in particular to a glue dispensing component for a glue dispensing machine. Background Art
[0002] The dispensing assembly is a key component of a dispensing machine, controlling the flow of glue and dispensing accuracy. It typically consists of the following components: The adhesive cartridge: This is where the glue is stored. It is typically made of metal or plastic and can be a single- or two-component design, depending on the specific application. The needle: This is the part of the dispensing assembly that directly controls the flow of glue. Its size and shape affect dispensing accuracy and speed. Needles are often replaceable to accommodate different dispensing requirements. The valve system: This controls the opening and closing of the glue dispenser, thereby determining whether glue can flow. This is typically achieved through a solenoid valve, which precisely controls the flow of glue. The pressure device: This pressure device applies pressure to the cartridge, forcing glue to flow through the needle. This can be a pneumatic or hydraulic system, depending on the type of dispensing machine and its requirements. The controller: The controller is the heart of the dispensing machine, controlling the entire dispensing assembly, including the opening and closing of the glue dispenser, dispensing speed, and accuracy. The controller typically has a user interface for easy setup and adjustment.
[0003] The prior art provides a dispensing valve assembly and dispensing machine (Announcement No.: CN207385826U). This device includes a dispensing valve, a pneumatic diaphragm pump, a solenoid valve, and an air compressor. The dispensing valve includes a glue inlet, a glue outlet, and a pneumatic port. The pneumatic diaphragm pump includes a glue inlet, a glue outlet, and an air inlet. The glue inlet is connected to a glue tank for loading glue, and the glue outlet is connected to the glue inlet. The air compressor is connected to the solenoid valve inlet, and the air inlet and pneumatic port are both connected to the solenoid valve outlet. The air compressor supplies air to the pneumatic diaphragm pump, causing it to deliver a predetermined amount of glue to the dispensing valve. The air compressor also supplies air to the dispensing valve, causing the glue delivered by the pneumatic diaphragm pump to drip out of the glue outlet. This utility model can deliver a stable amount of glue, improving dispensing efficiency.
[0004] However, the device still has the following defects:
[0005] The foot switch will work normally if it is accidentally stepped on or pressed by other objects, but it is easy to cause false touch. At the same time, the workpiece speed is single, and beginners must adjust the speed slowly to work. When experienced workers are not focused, glue may overflow and need to be wiped later, which increases the operation time. Therefore, we need to propose a glue dispensing machine component.

[0040] Working principle: When the present invention is used, after the photoelectric switch 18 senses that there is a workpiece at the glue nozzle 10, the second solenoid valve 8 opens, and the second silicone tube 7 slowly injects glue under the action of the throttle valve 9. After the pedal switch 15 is pressed to trigger the machine to work, the first solenoid valve 6 opens, and the machine enters a fast glue-discharging state. The first silicone tube 5 quickly injects glue. After the workpiece leaves the glue nozzle 10, the photoelectric switch 18 senses that there is no workpiece at the glue nozzle 10, and the pedal switch 15 stops working. The first solenoid valve 6 and the second solenoid valve 8 are closed at the same time. The air source box 13 pressurizes the inside of the glue storage barrel 2 to facilitate the outflow of the glue inside the glue storage barrel 2. The pressure reducing valve 3 prevents the glue pressure inside the liquid separation block 4 from being too high, which may damage the subsequent pipelines. The suction cylinder 11 sucks back the excess glue, and the suction is rapid and the suction volume is constant.
[0041] Turn on the motor 173, which drives the screw 172 to rotate. A threaded motion occurs between the screw 172 and the movable plate 174, controlling the movement of the movable plate 174.

The photoelectric switch 18 is installed on the upper end of the movable plate 174 through the insertion rod 175 and the elastic block 176. The insertion rod 175 and the elastic block 176 facilitate the loading and unloading of the photoelectric switch 18.
