DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] A one-way feeding component of a decentralized short-process printing device comprises a feeding pipeline 1, a closing cover 2 and a spraying pipe 3.
[0024] A plurality of inverted plugging corners 4 are provided on the inner wall of the feed pipe 1. The plurality of inverted plugging corners 4 are divided into four groups and evenly distributed in layers on the inner wall of the feed pipe 1. The inverted plugging corners 4 are horn-shaped, and a retention head 5 is provided at the end of the inverted plugging corner 4. The inverted plugging corners 4 are inverted toward one side of the closing cover 2. In order to meet the deformation requirements of the inverted plugging corners 4, the inverted plugging corners 4 are made of soft elastic material. When the number of inverted plugging corners 4 is large, mutual squeezing can fully seal the feed pipe 1.
[0025] Twelve positioning rods 6 are provided on the inner side of the closing cover 2 . The positioning rods 6 are evenly distributed on the inner edge of the closing cover 2 , and the positioning rods 6 are all inserted into the side wall of the feed pipe 1 , so that the closing cover 2 can stably approach or move away from the feed pipe 1 .
[0026] In order to open the closing cover 2, a support rod 7 is provided at the central position of the inner side of the closing cover 2, and a support rod top cover 8 is provided at the central position of the spray pipe 3. When the spray pipe 3 is inserted into the feed pipe 1, the support rod top cover 8 pushes the closing cover 2 out through the support rod 7, and the passage is opened. In order to allow the spray pipe 3 to be fully inserted into the feed pipe 1, the support rod 7 is movable and penetrates the closing cover 2. In order to limit the movable area of the support rod 7, a limit block 14 is provided at the end and the middle position of the support rod 7. In order to close the closing cover 2, a pull ring 9 is provided at the end of the support rod 7, and correspondingly, a connecting rope 10 is provided at the support rod top cover 8, and a draw hook 11 is connected to the end of the connecting rope 10. When the spray pipe 3 is withdrawn, the support rod top cover 8 pulls the support rod 7 through the connecting rope 10, so that the closing cover 2 and the feed pipe 1 are closed.
[0027] In order to improve the sealing performance, a plurality of wavy convex rings 12 are provided on the outer wall of the spray pipe 3 , and the plurality of wavy convex rings 12 cooperate with the inverted plugging corners 4 for sealing; a sealing member 13 is provided on the inner edge of the closing cover 2 .
[0028] When using this device, the draw hook 11 is inserted into the pull ring 9, and the operator inserts the spray pipe 3 into the feed pipe 1. At this time, the spray pipe 3 opens several inverted plugging corners 4, and at the same time, the support rod top cover 8 opens the closing cover 2 through the support rod 7. When the spray pipe 3 is inserted into place, the inverted plugging corners 4 cooperate with several wavy convex rings 12 embedded in the outer wall of the spray pipe 3 to ensure a certain degree of sealing, which can prevent the material from overflowing from the feed pipe port 1. When the infusion is completed, the spray pipe 3 is withdrawn, and the closing cover 2 and the feed pipe 1 are closed under the traction of the connecting rope 10. During the withdrawal of the spray pipe 3, part of the residual liquid brought out is retained in the inverted plugging corners 4. When the spray pipe 3 is inserted next time, the residual liquid can still be flushed into the dyeing tank.
