Glue supply system and spraying production equipment

Abstract

The invention discloses a glue supply system and spraying production equipment. The glue supply system comprises a glue supply unit and a control unit. The glue supply unit comprises a glue heating and stirring barrel, a glue inlet connecting pipe, a glue outlet pipe, a screw pump and a screw pump driving device. The control unit comprises a PLC, a first electromagnetic valve, a first pressure sensor and a second electromagnetic valve. The PLC is used for controlling the screw pump driving device to work. The PLC controls the first electromagnetic valve to be opened and closed. The first pressure sensor is arranged in the glue outlet pipe. The second electromagnetic valve is arranged at the joint of the glue outlet pipe and a glue gun. The first pressure sensor is arranged in the glue outlet pipe, and the PLC controls the opening and closing of the first electromagnetic valve and the second electromagnetic valve, so that the glue amount is controlled, the uniform glue outlet amount each time can be ensured, and the problem of non-uniform door plate spraying caused by the non-uniform glue outlet amount is solved.

Description

technical field [0001] The invention belongs to door panel spraying technology, in particular to a glue supply system and spraying production equipment. Background technique [0002] In the glue supply system of the existing door panel spraying production equipment, due to the lack of control over the glue output, a large amount of glue is wasted, and the amount of glue sprayed each time is uneven, which easily causes uneven glue spray on the door panel. Contents of the invention [0003] In order to solve the above problems, the present invention adopts the following technical solutions. [0004] A glue supply system, which includes a glue supply unit and a control unit; the glue supply unit includes a glue heating mixing barrel, a glue inlet connecting pipe, a glue outlet pipe, a screw pump and a screw pump driving device; wherein the glue heating The mixing barrel is provided with a glue outlet, one end of the glue inlet connecting pipe is connected with the glue outle...

AI Technical Summary

Problems solved by technology

[0005] Compared with the prior art, the glue supply system described in the present invention has the following beneficial effects: a glue supply system, which includes a glue supply unit and a control unit; Glue connecting pipe, rubber outlet pipe, screw pump and screw pump driving device; wherein, the rubber material heating and mixing barrel is provided with a rubber material outlet, and one end of the glue inlet connecting pipe is connected with the rubber material outlet, The other end of the glue inlet connecting pipe is connected with the glue outlet pipe; one end of the glue outlet pipe is connected with the screw pump, the other end of the glue outlet pipe is connected with a glue gun, and the screw pump driving device is connected with the screw pump connected, and the screw pump driving device drives the screw pump to work; the control unit includes a PLC controller, a first solenoid valve, a first pressure sensor, and a second solenoid valve; wherein, the PLC controller and the The driving device of the screw pump is connected, and the PLC controller controls the driving device of the screw pump; The first electromagnetic valve is opened and closed; the first pressure sensor is arranged in the rubber outlet pipe and connected to the PLC controller, and the first pressure sensor is used to detect the pressure of the glue in the rubber outlet pipe; The second solenoid valve is set at the connection between the glue outlet pipe and the glue gun; by setting the first pressure sensor in the glue outlet pipe, and the PLC controller controls the first solenoid valve and the second solenoid valve The opening and closing of the second solenoid valve realizes the control of the amount of glue, so it can ensure that the amount of glue is uniform each time, thus solving the problem of uneven spraying on the door panel due to uneven glue amount.
