The valve stem 8 is rotatably arranged in the shell 5 through the threaded connection between the piston 9 and the shell 5. When the air port 2 7 takes in air and the air port 1 6 discharges air, the air pressure at the upper part of the piston 9 in the shell 5 is much higher than the air pressure at the lower part of the piston 9, and the piston 9 is threadedly connected to the inner wall of the shell 5. Therefore, the high air pressure in the upper part of the shell 5 drives the piston 9 to rotate and move downward, thereby driving the valve stem 8 to rotate. The rotation of the valve stem 8 causes the valve core 15 to screw into the conical valve port 14, completing the cutoff of the glue in the oblique tee 1, and a plurality of warning mechanisms are evenly distributed in parallel on the outer wall of the shell 5.

[0022] A magnet is arranged inside the piston 9, and the magnet generates attraction to the magnetic induction switch, so that the switch is connected to the power supply and works.

[0023] The warning mechanism includes an integrated block 16 fixed on the outer wall of the shell 5, and a cavity 17 is opened in the integrated block 16. A magnetic induction switch is arranged on the inner wall of the cavity 17 close to the shell 5. The magnetic induction switch is electrically connected to a warning light 18 and a power supply 19. The warning light 18 is arranged on the outside of the integrated block 16.

[0024] The magnetic induction switch includes a switch box 20 fixed on the inner wall of the cavity 17, and an electrode 1 21 parallel to the shell 5 is arranged on the side of the switch box 20 close to the shell 5. An electrode 2 22 parallel to the electrode 1 21 is also arranged in the switch box 20, and an end of the electrode 2 22 away from the electrode 1 21 is arranged in the switch box 20 through a plane spring 23. The electrode 1 21 and the electrode 2 22 are both made of magnetic materials. When the piston 9 approaches the warning mechanism, the magnet in the piston 9 magnetizes the electrode 1 21 and the electrode 2 22, so that the electrode 1 21 and the electrode 2 22 are in contact, thereby connecting the circuit and making the warning light 18 light up.

[0025] When the piston 9 moves upward and approaches the warning mechanism, the electrode 2 22 and the electrode 1 21 are magnetized and attracted together. After the power is connected, the warning light 18 turns on. The staff can judge the position and state of the piston 9 at this time according to the opening and closing of the warning lights 18 of the multiple warning mechanisms outside the shell 5. When the control device is in the glue release stage (that is, the valve core 15 is rotated out of the conical valve port 14, and the glue flows), but the piston 9 does not move upward (that is, the warning light 18 at the bottom of the outer wall of the shell 5 is on, and the other warning lights 18 are off), the control device can be judged to have a fault according to the warning mechanism.

[0026] The integrated block 16 is provided with an opening for replacing the power supply 19 , and the power supply 19 can also be connected to an external power supply through the opening.

[0027] The straight branch pipe 1 2 and the straight branch pipe 2 3 are both provided with a radiation temperature sensor 26, and an anti-sticking cover is provided outside the radiation temperature sensor 26. The radiation temperature sensor 26 is used to detect the glue temperature in the inclined three-way pipe 1. The control device can be used to control water glue or oil glue.

[0028] The inclined tee pipe 1 is provided with a heating tube 27 on its outer sleeve, and the heating tube 27 is electrically connected to the radiation temperature sensor 26. The radiation temperature sensor 26 detects that the temperature of the glue in the inclined tee pipe 1 is relatively low (lower than the temperature when the glue enters the pipe). To prevent the glue from condensing, the radiation temperature sensor 26 heats the temperature of the glue in the inclined tee pipe 1 to a suitable temperature through the heating tube 27.

[0029] The air port 1 6 and the air port 2 7 are both connected to the air pump through the solenoid valve 24. The air pump supplies air to the air port 1 6 and the air port 2 7 through the solenoid valve 24. The air pump is responsible for extracting air while providing gas, so that the air pressure at the upper and lower ends of the piston 9 in the shell 5 is inconsistent, and the up and down movement of the piston 9 is controlled according to the inconsistency of the air pressure at the upper and lower ends of the piston 9.

[0030] The straight branch pipe 1 2 of the inclined tee pipe 1 is the glue inlet, and the straight branch pipe 2 3 is the glue outlet. A manual stop valve 25 is provided on the straight branch pipe 2. Glue enters from the straight branch pipe 1 2 and exits from the straight branch pipe 3. When the control device or other production equipment fails, the manual stop valve 25 can quickly block the glue from entering the inclined tee pipe 1.

[0031] The working principle of the present invention is as follows: the manual stop valve 25 is opened, and the glue enters the straight branch pipe 2. The solenoid valve 24 is controlled by the controller (the controller is a conventional technical means) to supply air to the air port 6 and exhaust the air from the air port 7. The air pressure causes the piston 9 to move toward the upper part of the shell 5. Since the piston 9 is threadedly connected to the inner wall of the shell 5, the piston 9 rises in a spiral manner, driving the valve stem 8 to rotate, so that the valve core 15 is screwed out of the conical valve port 14, and the glue enters the straight branch pipe 23 from the straight branch pipe 2. When the set time is reached, the controller controls the solenoid valve 24 to supply air to the air port 27 and exhaust the air from the air port 6, so that the piston 9 moves downward (the spring 11 resets), driving the valve stem 8 to rotate in the opposite direction, so that the valve core 15 is screwed into the conical valve port 14, blocking the conical valve port 14, so that the glue cannot enter the straight branch pipe 3 from the straight branch pipe 2, thereby completing one coating, and performing this reciprocating process. When the piston 9 moves upward, the warning light 18 of the warning mechanism on the outer wall of the shell 5 opens and closes in sequence, and the position of the piston 9 is displayed in real time. When the piston 9 is close to the warning mechanism, the magnet inside the piston 9 will magnetize the electrode 1 21 and the electrode 2 22, so that the electrode 1 21 and the electrode 2 22 are adsorbed together, and the power supply 19 is connected to the warning light 18, and the warning light 18 is on; and when the piston 9 is away from the warning mechanism, the magnetized electrode 1 21 and the electrode 2 22 lose magnetism, thereby disconnecting, and the warning light 18 is turned off. Employees can check the internal situation of the valve according to the opening and closing of the warning light 18. When a production failure occurs, employees can directly close the manual stop valve 25 to stop the supply of glue to prevent the glue from spraying on the ground or the tape roll from being scrapped; through automated control, the product standards are unified.
