[0026] The effect achieved by the entire embodiment is that by controlling the servo motor 52 to start, the servo motor 52 drives the gear 56 to rotate, the gear 56 engages the rack 57, and the horizontal force exerted on the rack 57 is transmitted to the first-level plate frame 55, so that the first-level plate frame 55 slides in the second slide 58 with the help of the guide rail, thereby the first-level plate frame 55 moves horizontally outward. At the same time, the first-level plate frame 55 will drive the belt assembly composed of the synchronous belt 511 and the synchronous wheel 513 to move horizontally, and the first connecting member 510 clamps one side of the synchronous belt 511, and the first connecting member 510 is fixed on the mounting frame 53, thereby the first-level plate frame 55 is horizontally moved outward. During the horizontal outward movement, the synchronous belt 511 will rotate clockwise, and the second connecting frame 512 will fix the other side of the synchronous belt 511 to the secondary plate frame 514. Therefore, under the connecting action of the second connecting frame 512, the secondary plate frame 514 is further subjected to the force of moving outward. With the assistance of the guide rail, the secondary plate frame 514 slides in the third slide 59, that is, the secondary plate frame 514 extends outward from the primary plate frame 55, driving the side frame 51 and multiple groups of spray heads 4 to approach the vulcanizer mold, controlling the release agent in the pressure barrel to be sprayed from the spray head 4 to the vulcanizer mold, avoiding waste of the release agent and spraying accurately.

[0027] The method of use and working principle of this device: When using the independent adjustable three-arm truss for spraying the release agent, it is installed next to the vulcanizer. The spray head 4 is connected to a 40L pressure barrel with pneumatic stirring. The release agent is stored in the barrel. The multiple groups of spray heads 4 are divided into two groups, upper and lower, which are fixedly installed on both sides of the side frame 51 respectively, spraying the release agent in the upper and lower directions. Turn the hand wheel 21, the hand wheel 21 drives the primary bevel gear 22 to rotate, thereby engaging the secondary bevel gear 23 to rotate, and the secondary bevel gear 23 drives the screw 24 on one side of the load-bearing column 1. The screw 24 rotates sideways, and the threaded rotation in the connecting seat 25 generates an engaging force, and the component of the engaging force is applied to the connecting seat 25, thereby being transmitted to the mounting frame 53, so that the mounting frame 53 moves up and down under the cooperation of the first slide 54 and the guide rail, thereby adjusting the height of the truss X-axis mechanism 5, thereby adjusting the spraying height of the spray head 4 thereon, and adaptively adjusting the release agent spraying height according to the different mold heights in the vulcanizer. The other two groups operate independently in the same way. Then, the servo motor 52 is controlled to start, and the servo motor 5 2 drives the gear 56 to rotate, and the gear 56 meshes with the rack 57. The horizontal force on the rack 57 is transmitted to the first plate frame 55, so that the first plate frame 55 slides in the second slide 58 with the help of the guide rail, thereby the first plate frame 55 moves horizontally outward. At the same time, the first plate frame 55 drives the belt assembly consisting of the synchronous belt 511 and the synchronous wheel 513 to move horizontally, and the first connecting member 510 clamps one side of the synchronous belt 511, and the first connecting member 510 is fixed to the mounting frame 53. Therefore, during the process of the first plate frame 55 moving horizontally outward, In the process, the synchronous belt 511 will rotate clockwise, and the second connecting frame 512 fixes the other side of the synchronous belt 511 to the secondary plate frame 514. Therefore, under the connecting action of the second connecting frame 512, the secondary plate frame 514 is further subjected to the force of moving outward. With the assistance of the guide rail, the secondary plate frame 514 slides in the third slide 59, that is, the secondary plate frame 514 extends outward from the primary plate frame 55, driving the side frame 51 and multiple groups of spray heads 4 to approach the vulcanizer mold, and controlling the release agent in the pressure barrel to be sprayed from the spray head 4 to the vulcanizer mold.
