[0019] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.
[0020] See also Figure 1 The utility model provides a spray device with a cloth wheel for a dyeing machine, comprising a spray pipe 1, a spray port 2 and an anti-blocking self-sealing structure 3. The spray port 2 is opened on the outer surface of the spray pipe 1, and the spray port 2 is connected to the inner side of the spray pipe 1, and the anti-blocking self-sealing structure 3 is arranged inside the spray port 2.
[0021] See also Figure 2 , Figure 4 and Figure 5 The anti-blocking self-sealing structure 3 in the utility model includes a plug-in slot 31, a piston drive member 32, a No. 1 spring 33, a connecting shaft 34, a sliding cover 35 and a through-port 36. The plug-in slot 31 is provided on the left side wall inside the spray pipe 1. The inner side of the plug-in slot 31 is slidably connected to the rod of the piston drive member 32, and the piston drive member 32 slides along the inner side of the spray pipe 1 in a sealed manner. A No. 1 spring 33 is installed on the left side wall inside the spray pipe 1. The two ends of the No. 1 spring 33 are respectively connected to the spray pipe 1 and the piston drive member 32. The No. 1 spring 33 controls the movement and reset of the piston drive member 32. A connecting shaft 34 is installed at the axis center of the right end of the piston drive member 32. The outside of the connecting shaft 34 is connected to the sliding cover 35 through a connecting rod. The sliding cover 35 fits the inner wall of the spray pipe 1 and blocks the inner surface of the spray port 2. The sliding cover 35 is provided with a through-port 36 inside and outside.
[0022] To further explain, the longitudinal section of the sliding cover 35 is arc-shaped, and the curvature of the sliding cover 35 matches the curvature of the inner wall of the spray pipe 1 to ensure that the sliding cover 35 can fit tightly against the inner wall of the spray pipe 1, thereby blocking the inner surface of the spray port 2.
[0023] To further explain, when the rod of the piston driving member 32 is completely retracted into the inner side of the insertion groove 31 , the through opening 36 will correspond to the position of the spray port 2 to ensure that the through opening 36 will not move excessively and can be normally connected with the spray port 2 .
[0024] It is further explained that the horizontal length of the through opening 36 is at least three times the horizontal length of the spray port 2 , so that the through opening 36 can be more easily connected to the spray port 2 .
[0025] See also Figure 3The anti-blocking self-sealing structure 3 in the utility model also includes a connecting groove 37, a support rod 38, a head 39 and a No. 2 spring 310. A connecting groove 37 is opened on the outer surface of the sliding cover 35. The number of the connecting grooves 37 and the through opening 36 is the same. A support rod 38 is fixed to the bottom surface of the connecting groove 37. A head 39 is slidably sleeved on the surface of the support rod 38. The head 39 can be plugged into the inner side of the spray port 2, so as to plug and block the spray port 2 to prevent the dye from condensing into blocks on the inner side of the spray port 2. A No. 2 spring 310 is installed on the bottom surface of the connecting groove 37. The two ends of the No. 2 spring 310 are respectively connected to the connecting groove 37 and the head 39, and the No. 2 spring 310 provides pop-up power for the head 39.
[0026] Further explanation: the end of the sealing head 39 is designed with a round head structure, so that the sealing head 39 can slide out from the inside of the spray port 2 and is not easily stuck.
[0027] Here’s how it works:
[0028] First, when in use, the dye liquid will be added from the opening at the right end of the spray pipe 1. The added dye liquid will generate hydraulic pressure inside the spray pipe 1, and the piston driving member 32 will be pushed by the hydraulic power. The piston driving member 32 will then drive the sliding cover 35 to slide along the inner wall of the spray pipe 1 through the connecting shaft 34 until the rod of the piston driving member 32 is completely retracted into the inner side of the plug-in groove 31. At this time, the through opening 36 on the sliding cover 35 moves to the corresponding position on the inner surface of the spray port 2, and the dye liquid can pass through the through opening 36 and spray outward through the spray port 2, thereby realizing the normal spraying operation.
[0029] Second, when spraying stops, the hydraulic pressure inside the spray pipe 1 decreases. At this time, the No. 1 spring 33 overcomes the hydraulic pressure and pushes the piston drive member 32 to move right and reset. The piston drive member 32 then drives the sliding cover 35 to slide and reset through the connecting shaft 34, so that the position of the through port 36 is offset from the spray port 2, thereby blocking the spray port 2.
[0030] Third, by setting the head 39, when the connection groove 37 coincides with the position of the spray port 2, the No. 2 spring 310 uses its own elastic force to pop the head 39 out of the connection groove 37 along the support rod 38, so that the head 39 is plugged into the inner side of the spray port 2, thereby plugging and blocking the spray port 2 to prevent the dye from condensing into blocks on the inside of the spray port 2 to maintain the normal use of the spray port 2. The anti-blocking self-sealing structure 3 can open and close automatically according to the working state of the spray pipe 1, without the need for electric drive, and has low cost.
[0031] The utility model provides a spray device with a cloth wheel for a dyeing machine, wherein an anti-blocking self-sealing structure 3 is arranged inside the spray port 2. When spraying stops, the hydraulic pressure inside the spray pipe 1 is reduced, and at this time, the No. 1 spring 33 overcomes the hydraulic pressure to push the piston driving member 32 to move right and reset, and the piston driving member 32 then drives the sliding cover 35 to slide and reset through the connecting shaft 34, so that the position of the through port 36 and the spray port 2 is staggered, thereby blocking the spray port 2. When the position of the connecting groove 37 and the spray port 2 coincides, the No. 2 spring 310 uses its own elastic force to pop the sealing head 39 outward along the support rod 38 to the connecting groove 37, so that the sealing head 39 is plugged into the inner side of the spray port 2, thereby plugging and blocking the spray port 2, preventing the dye from condensing into blocks inside the spray port 2, so as to maintain the normal use of the spray port 2, and the anti-blocking self-sealing structure 3 can be opened and closed automatically according to the working state of the spray pipe 1, does not need electric drive, and has low cost.
