During the process that the wood door passes below the distributed glue spraying nozzle, the glue sprayed by the distributed glue spraying nozzle is coated on the wood door.

[0004] However, the existing glue spraying machine does not have a mechanism for shaping the wood door. If the wood door is damp and the surface is uneven, the subsequent glue spraying and compounding process will be affected, and there is room for improvement. CONTENT OF THE INVENTION

[0007] A control panel is fixedly installed on the rack and used for inputting a door plate length signal and a starting signal.

[0008] An induction control module is fixedly installed on the rack. A signal input end is signal-connected with a signal output end of the control panel. The induction control module is used for receiving the door plate length signal and the starting signal, detecting the position of the door plate, outputting a first control signal when the door plate passes below the distributed glue spraying nozzle, and outputting a second control signal when the door plate completely passes below the distributed glue spraying nozzle.

[0010] The signal input end of the shaping driving mechanism and the wood door conveying belt is signal connected with the signal output end of the induction control module, and the shaping driving mechanism and the wood door conveying belt receive the first control signal and start, and receive the second control signal and stop running.

[0011] Through the above technical scheme, in the actual production process, the operator can transfer the wood door to be sprayed to the wood door conveying belt, and input the start signal and the wood door length signal through the control panel; the wood door conveying belt starts after receiving the start signal, and conveys the wood door to the lower side of the compression roller, and the shaping driving mechanism runs after receiving the start signal, and the surface of the wood door can be rolled and shaped by the compression roller, so that the flatness of the surface of the wood door is improved, and the technical effect of automatically shaping the wood door can be realized; when the part of the wood door conveyed by the compression roller moves through the induction control module, the induction control module outputs the first control signal, the glue spraying driving mechanism drives the distributed glue spraying nozzle to reciprocate and slide, the distributed glue spraying nozzle starts to spray the glue on the surface of the wood door, and the technical effects of automatically sensing the wood door and automatically spraying the glue can be realized; when the wood door completely passes through the induction detection module, the induction detection module outputs the second control signal, and the distributed glue spraying nozzle, the glue spraying driving module, the wood door conveying belt and the shaping driving mechanism stop running, and the technical effect of automatically closing the distributed glue spraying nozzle, the glue spraying driving module, the wood door conveying belt and the shaping driving mechanism can be realized, and the use convenience of the glue spraying machine is improved.

When the end of the wooden door passes through the infrared distance sensor, the inductive distance detected by the infrared distance sensor is greater than the set value, the single-chip microcomputer can judge that the end of the wooden door has passed through the infrared distance sensor, the single-chip microcomputer outputs the second control signal, and the glue spraying driving module, the distributed glue spraying head, the wooden door conveying belt and the servo motor stop running.

[0021] Preferably, a signal input end of the infrared distance sensor is connected with a signal output end of the single-chip microcomputer, and the infrared distance sensor receives the second control signal and stops running.
