Glue gun stable in pressure and flow

Abstract

A glue gun stable in pressure and flow comprises a controller, a pushing device and a glue outlet. A gun body is connected with the pushing device through a connection frame. The glue gun stable in pressure and flow further comprises a pressure pipe and a pressure transmitter communicating with the pressure pipe. The controller is connected with the pressure transmitter and the pushing device. A connection piece, a valve rod, a seal guide piece, a valve element and a valve ball fixed to the tail end of the valve rod are arranged in the gun body. The valve element and the connection piece are fixed to the two ends of the gun body correspondingly. The seal guide piece is fixed to the middle in the gun body. The valve element, the pressure pipe and the glue discharge head are sequentially andfixedly connected in a sealed manner. One end of the connection piece is connected with the top end of the valve rod. The other end of the connection piece is fixedly connected with the pushing device. The valve rod penetrates through the seal guide piece. The valve ball at the tail end of the valve rod is matched with the valve element. On the gun body, a glue inlet pipe communicates between theseal guide piece and the valve element. The glue gun stable in pressure and flow has the beneficial effects that the cost is low, the pressure and flow of the glue gun can be guaranteed to be stable,so that the glue output amount is constant, and metering is accurate.

Description

technical field [0001] The invention relates to the field of gluing devices, in particular to a gluing gun with constant voltage and flow. Background technique [0002] Glue gun is a device used to spray or inject adhesive onto the surface of the adhered object. It may be used where glue is required. It is widely used in architectural decoration, electronic appliances, automobiles and auto parts, and ships. and container industries. [0003] In recent years, the government has vigorously advocated energy saving and emission reduction. This concept has been deeply rooted in the hearts of the people. Manufacturers have made great efforts to reform the use of glue and mechanical structures in response to this consumer psychology. Driven by this concept, automatic glue application technology has emerged. Compared with manual gluing and pneumatic gluing, the cost of automatic gluing is lower than them and higher in production efficiency, and the quality is better than manual glu...

Problems solved by technology

[0004] However, due to the flow pulsation of the glue pump, automatic glue application cannot achieve accurate metering

For this reason, in the prior art, equipment such as metering pumps and metering cylinders are used to ensure the output of glue to achieve precise metering. For example, the five-axis robot gluing equipment and process technology described in the patent application number CN201510398716.6, which uses metering Pump; as a metering high-pressure plunger pump described in patent application number CN201420639656.3, the metering parts are composed of metering cylinders, metering cylinder pistons and pusher sliders; the above two devices use metering pumps, metering cylinders, etc. Equipment and metering structures are complex to manufacture, expensive and difficult to promote in large areas
