There is a gap between the through holes 425 and the pins 412 and 415. A first adjusting differential head 426 and a first elastic pin are provided on both sides of the front end of the adjusting block 42 427. The first adjusting differential head 426 is pressed against the positioning cylinder pin 415 on the fixed block 41, and the first elastic pin 427 is pressed against the positioning cylinder 412 pin on the fixed block 41. When the first adjusting differential head 426 is adjusted When the first adjusting differential head 426 pushes the fixed block 41, the fixed block 41 is fixed and the adjusting block 42 slides relative to the fixed block 41, thereby driving the nozzle 3 connected with the leveling device to move, so that the nozzle 3 is in X The axial position is adjusted to ensure that the nozzle 3 and the nozzle 2 are connected end to end. When the first adjusting differential head 426 pushes the fixed block 41, the first elastic pin 427 always acts on the adjusting block 42 to make it move in the opposite direction. Therefore, when the position of the nozzle 3 on the X axis is adjusted excessively, Rotate the first adjusting differential head 426 in the reverse direction, and the nozzle 3 can automatically return to its position.
[0042] The top surface of the adjusting block 42 is provided with a first positioning post 423, a second positioning post 424 and a sliding groove 422 which are respectively connected to the longitudinal adjustment device and the leveling device, such as image 3 , 8 As shown in and 11, the longitudinal adjustment device includes a slider 43, a second adjusting differential head 433, and a second elastic pin 434. The slider 43 is provided with a through hole 431 corresponding to the first positioning post 423, passing through the first positioning post 423 is matched with the through hole 431 on the slider 43. The slider 43 is sleeved on the first positioning post 423 on the adjusting block 42 and is accommodated in the sliding groove 422. The size of the sliding groove 422 matches the slider 43, so that The slider 43 can only move along the chute 422 provided in the longitudinal direction of the adjustment block 42. There is a gap between the through hole 431 on the slider 43 and the first positioning post 423, so that the slider 43 and the adjustment block 42 can move relatively , The front end of the slider 43 is provided with a second adjusting differential head 433, the back end of the slider 45 is provided with a second elastic pin 434, the end surfaces of the second adjusting differential head 433 and the second elastic pin 434 are respectively pressed against The first positioning post 423 on the adjusting block 42 adjusts the second adjusting differential head 433. When the second adjusting differential head 433 pushes the adjusting block 42, the adjusting block 42 is fixed and the slider 43 moves along the sliding groove 422. Move longitudinally to adjust the longitudinal distance between the nozzle 3 and the nozzle 2.
[0043] Such as image 3 , 7 As shown in and 9, the leveling device includes a nozzle connecting plate 44, a third adjusting differential head 444 and a third elastic pin 445. The nozzle connecting plate 44 and the positioning pin 62 and the through hole 64 provided on the top surface of the mounting plate 6 pass through The nozzle connection plate 44 is provided with a through hole 442 corresponding to the second positioning post 424 and a through hole 441 corresponding to the positioning pin 432 on the top surface of the slider 43, which are fixedly connected by screws. The positioning pin 432 on the 43 is matched with the through hole 441 on the nozzle connecting plate 44. The nozzle connecting plate 44 is sleeved on the sliding block 43 and the adjusting block 42. A third adjusting differential head 444 is provided on both sides of the front end of the nozzle connecting plate 44. And the third elastic pin 445, the third adjusting differential head 444 and the third elastic pin 445 are respectively pressed against the two ends of the slider 43. When the third adjusting differential head 444 is adjusted, the nozzle connecting plate 44 can be wound around the slider. The positioning cylindrical pin 432 on the 43 rotates to realize the adjustment of the angular position of the nozzle 3 and ensure that the nozzle 3 and the nozzle 2 are completely parallel. Since the differential head 444 pushes the slider 43, the elastic pin 445 always acts on the slider 43 to make it reversely rotate. Therefore, when the position of the nozzle 3 is adjusted excessively, the differential head 444 is rotated reversely. , Nozzle 3 can rotate automatically. After adjusting the angular position of the nozzle 3, the locking screw 451 on the pressing block 45 penetrates the through hole 443 on the nozzle connecting plate and the through hole 429 on the adjusting block 42 to fix the connecting plate 44 on the adjusting block 42, thereby Fix the angular position of the nozzle 3. There is a disc spring on the locking screw 451, which can be self-locking. When adjusting the differential head, when it reaches a certain required position, loosen the differential head. Even if there is no locking screw, it will not be affected by the spring. The function makes the position of the nozzle change, that is, when adjusting, which position needs to be adjusted, which position can be reached, and the position will not change without external force. After adjusting the Y-axis and X-axis positions of the nozzle 3, the adjusting block 42 and the fixing block 41 are locked by the locking screw 428, thereby fixing the positions of the nozzle 3 in the Y-axis and X-axis.
[0044] The above-mentioned elastic pin that plays the role of returning can also be a spring. In the present invention, a positioning pin is arranged between the horizontal adjustment device, the longitudinal adjustment device and the leveling device, which can effectively prevent deviation from occurring during the locking process. Improve its adjustment accuracy. The mounting plate 6 of the movable nozzle 3 of the present invention is inserted into the mounting hole 12 of the bottom plate from bottom to top. The mounting plate 6 is also provided with a process hole 63 to facilitate the removal of the movable nozzle 3 when the nozzle fails, only the nozzle and its mounting plate need to be removed , The adjustment part on it basically does not move, when the nozzle is installed again, no adjustment is needed or only slight adjustment can meet the required requirements. While reducing labor intensity, it saves adjustment time and makes maintenance easier.
[0045] It should be pointed out that any modification made according to the specific embodiments of the present invention does not depart from the spirit of the present invention and the scope of the claims.
