[0024] The piston rod of the reciprocating cylinder 6 can be reciprocated up and down and the distance is adjustable. The horizontal infusion tube 2 and the piston rod of the reciprocating cylinder 6 are offset when viewed from above, and will not collide or rub against each other.
[0025] An electric-controlled valve 22 is provided on the liquid spray head 21. The liquid spray head 21 and the electric-controlled valve 22 form a group, and there are two groups symmetrical on the left and right. The controller 11, the electric-controlled valve 22, and the liquid pump 13 are electrically connected. A PLC is preset in the controller 11 to realize the electric control opening and closing of the electric-controlled valve 22 and the liquid pump 13.
[0026] The electric control valve 22 is an electric control valve for pipelines, and the liquid spray head 21 is a diffusion structure, which further increases the effective area for spraying the bleaching agent.
[0027] There are six stirring plates 71 arranged in a circle, and a mixing hole 72 is opened on the stirring plate 71. The mixing hole 72 is an elliptical through hole. When the stirring plate 71 rotates, the bleaching agent and the pre-stored water will pass through each mixing hole 72 to form multiple liquid flows, further improving the mixing efficiency and the efficiency of preparing the bleaching solution.
[0028] A discharge port 41 is provided at the top of the bleaching frame 4, through which a certain amount of refined cotton can be placed.
[0029] A cover plate 42 is provided on the discharge port 41 , and bolts are preset on the cover plate 42 to seal and cover the discharge port 41 .
[0030] The outer wall of the bleaching frame 4 is provided with a transverse plate 5, on which a guide rod 51 is provided. The guide hole 10 and the guide rod 51 are slidably sleeved. The outer wall of the guide rod 51 has a smooth graphite coating layer, which improves the sliding smoothness of the guide rod 51 in the guide hole 10.
[0031] The guide hole 10 and the guide rod 51 form a group, which are two groups symmetrical on the left and right, so as to realize the stable guidance of the bleaching frame 4 into the bleaching box 3. When the bleaching solution is prepared, the lifting cylinder 43 is started to drive the bleaching frame 4 pre-stored with refined cotton to move downward into the bleaching box 3. During this process, the guide rods 51 on both sides will slide along the guide hole 10 vertically to avoid shaking of the bleaching frame 4 when it is placed in the bleaching box 3, thereby improving the stable guidance of the bleaching frame 4 into the bleaching box 3.
[0032] The inner side wall of the upper end of the bleaching box 3 is provided with a splash plate 31 to prevent the bleaching liquid from splashing out of the bleaching box 3 during stirring.
[0033] The bleaching box 3 is provided with a sealing sleeve 30, which is slidably sleeved with the main shaft 7. The sealing sleeve 30 is made of polyurethane rubber and has high elasticity and waterproof sealing properties, thereby ensuring the rotation and up and down sliding of the main shaft 7 and the sealing of this part.
[0034] When used in this embodiment: a certain amount of water is input into the bleaching tank 3, and then the controller 11 is started. The PLC in the controller 11 will start the liquid pump 13 and open the electric control valves 22 on both sides at the same time. At this time, the liquid pump 13 will pump the bleaching agent in the liquid storage tank 12 into the liquid infusion pipes 2 on both sides, and then input it into the bleaching tank 3 through the liquid spray heads 21 on both sides. Then the controller 11 is turned off and the reciprocating cylinder 6 and the motor 62 are started. At this time, the bleaching agent is no longer input, and the stirring plate 71 is driven to rotate at a uniform speed through the main shaft 7. At the same time, the piston rod of the reciprocating cylinder 6 will drive the rotating stirring plate 71 to move back and forth up and down, so as to achieve up and down reciprocating mixing and stirring of the bleaching agent and the pre-stored water.
[0035] The above operation improves the mixing degree between the input bleaching agent and the pre-stored water as a whole, improves the mixing quality of the bleaching solution, and thus ensures the rinsing effect of the later bleaching solution on the refined cotton.
