Description

Technical Field

[0001] This utility model relates to the field of glue dispensing devices, and in particular to a high-efficiency glue dispensing device for a servo motor. Background Technology

[0002] Among the many dispensing equipment, the frequency and ease of maintenance, as well as the cost of replacing easily worn parts, are important references for evaluating a dispensing equipment. Currently, dispensing equipment on the market is generally characterized by relatively difficult maintenance and short wear cycles. The relatively difficult maintenance is mainly reflected in the fact that most dispensing equipment has relatively complex parts. Due to the variety of fillers used in the equipment, the viscosity of the fillers also varies. Moreover, the fillers used in dispensing equipment are easily affected by temperature. In relatively low temperature environments, the viscosity of the fillers often increases.

[0003] The existing publication number CN110732462A discloses a high-filler dispensing head device, including a main body. A solenoid valve is installed near the upper right end of the main body. A dispensing head is installed near the bottom front of the main body. An adapter plate is provided at the rear end of the dispensing head. A valve core mounting block is installed at the rear end of the adapter plate. A first dispensing hole is opened near the upper end of the valve core mounting block. A second dispensing hole is opened below the first dispensing hole. A first dispensing hole is opened near the bottom of the valve core mounting block. A second dispensing hole is opened to the right of the first dispensing hole. A dispensing valve vent is opened below the second dispensing hole. A dispensing valve vent is opened in the middle of the valve core mounting block. A cylinder liner is installed at the upper end of the dispensing head. A piston ring is provided inside the cylinder liner. A piston rod is installed above the piston ring.
