Embodiment 1

[0025] like figure 1 As shown, the roller 1 and the roller 2 of the hot air blower rotate synchronously and oppositely, the adhesive tape 6 is placed on the roller 2, and the material 5 is placed between the roller 1 and the roller 2. When the hot air blower is working, the numerically controlled air nozzle positioning device 7 first calls the sealing control command from the memory module, and drives the air nozzle 4 to move quickly to a preset position through the motor driver, and the air nozzle 4 blows hot air through the air heater 3 , the tape 6 near the tuyere becomes viscous after absorbing enough heat, and is sealed and bonded to the material 5 after being rolled and pressurized by the roller 1 and the roller 2.

[0026] In this embodiment, the position of the tuyere 4 will shift rapidly according to the change of the sealing speed. First, the speed when the material is actually sealed is tested by the speed test module; then the theoretical speed of the current mater...

Embodiment 2

[0028] As a preferred solution of the present invention, the number of the motor 8 and the transmission device 9 can be respectively set to three, and each motor is connected to the corresponding transmission device. When the hot air blower is working, after the air nozzle reaches the preset position, firstly by changing the sealing control instruction in the memory module in the numerical control air nozzle positioning device 7, then the instruction is sent to the computer numerical control module, and the motor driver is controlled by the computer numerical control module. Its control drives the motor 8 representing a certain direction, and the motor drives the air nozzle 4 to move together with the transmission device connected to it. The three-dimensional movement of the air nozzle 4 up and down, left and right, or front and back can be realized by completing the driving of the above three motors and the three transmission devices through the motor driver.

Abstract

The invention relates to an air heater, in particular to a digital controller which can timely change the shift of the air nozzle of the air heater as well as the control method thereof. The invention utilizes the air heater to whiff the heated air on a belt via the air nozzle, the melted belt and the material are pressed by a roller for sealing, and the digital control nozzle locating device is used to control the shift of the air nozzle of the air heater. The digital control nozzle locating device provided by the invention can control the locating of the air nozzle according to the speed of the material in sealing, thermal transfer can be adjusted effectively, and the belt can be jointed with the material without the influence of uneven melting, thereby effectively guaranteeing the sealing quality of the material.

Description

technical field [0001] The invention relates to a hot air blower, in particular to a numerical control device and a control method for a hot air blower which can change the displacement of the air nozzle of the hot air blower in real time. Background technique [0002] The composite process of the existing tape-type waterproof clothing is as follows: the traditional hot air heater uses an air heater to heat the air, and the heated air is sprayed on the tape through the air nozzle, and the heat energy melts the hot-melt adhesive layer on the tape, and then passes through The rollers pressurize the melted tape and materials to create a seal. The hot air speed and hot air temperature are kept constant during operation, so that the hot melt adhesive layer on the adhesive tape is melted evenly. Generally, when the hot air blower is not working, the air nozzle is placed in a spare position where the hot air cannot blow the adhesive tape. When the hot air blower is working, the a...
