Utility Model Content

[0005] In view of this, the purpose of the utility model is to provide a water-saving dehydration and color-fixing printing and dyeing device to achieve the purpose of improving the dehydration efficiency.

[0006] In order to solve the above technical problems, the technical solution of the utility model is: a water-saving dehydration and color fixing printing and dyeing device, comprising a tank body, the upper end of the tank body has an opening, a cover plate is hinged on the tank body, a support shaft is rotatably connected to the tank body, a dehydration barrel is fixedly connected to the support rod, a drainage hole is opened on the side wall of the tank body, a dehydration hole is opened on the side wall of the dehydration barrel, a support rod is fixedly connected to the inner wall of the dehydration barrel, a support ball is fixedly connected to the support rod, and the projection of the support ball on the inner wall of the dehydration barrel is located inside the dehydration hole.

[0007] To implement the above technical solution, the cloth is placed in the dehydration barrel from the opening, and the support shaft rotates. The cloth adheres to the inner wall of the dehydration barrel due to the action of centrifugal force, and part of the cloth collides with the support balls and forms a cavity between the support balls and the dehydration holes, so that the dehydration holes cannot be blocked by the cloth. During the high-speed rotation of the support shaft, the water on the cloth is separated from the cloth and discharged from the dehydration holes, and then due to the action of gravity, the water moves down along the inner wall of the tank body and is finally discharged from the drainage hole, thereby achieving the purpose of high dehydration efficiency.

[0008] As a preferred solution of the utility model, a plurality of connecting holes are provided on the supporting ball, and the plurality of connecting holes are arranged along the center of the supporting ball, and the connecting holes penetrate the supporting ball.

[0009] By implementing the above technical solution, a small amount of water on the cloth can pass through the connecting holes to further promote the separation of the cloth and the water, thereby further improving the dehydration efficiency.

[0014] As a preferred solution of the utility model, a return pipe is fixedly connected to the water storage tank, and the return pipe is connected to the reuse water area and is located at the upper edge of the reuse water area.

[0015] To implement the above technical solution, since the return pipe is located at the upper edge of the reuse water area, it plays the role of a third filtration. As the amount of water in the reuse water area gradually increases, it is finally injected into the dyeing machine from the return pipe.

[0016] As a preferred solution of the utility model, a plurality of ventilation holes are provided on the cover plate, and the ventilation holes are connected with the opening.

At the same time, during the rotation of the cloth, water is discharged from the drainage holes, generating negative pressure in the dehydration barrel. The air pressure can be balanced through the air holes, thereby improving operation safety.

[0021] To implement the above technical solution, the cloth is passed around the rotating wheel. When the conveying motor is started, the rotating wheel can be rotated to make the cloth fall into the tank, eliminating the process of manual handling and greatly improving production efficiency.

[0022] As a preferred solution of the utility model, the column is slidably connected to a slider along its length direction, the slider is rotatably connected to a pressure roller, the pressure roller is arranged parallel to the rotating wheel, and a clamping area is formed between the pressure roller and the rotating wheel.

[0023] To implement the above technical solution, the cloth is passed around the rotating wheel, and the pressure roller is pressed on the cloth due to its own gravity to increase the friction between the cloth and the rotating wheel, thereby avoiding slipping between the rotating wheel and the cloth and improving the transmission efficiency of the cloth.

[0032] Circular baffles 321 are fixedly connected to both ends of the rotating wheel 32 to prevent the cloth from falling off the rotating wheel 32 .

[0033] The upper end of the column 31 is slidably connected with a slider 4 along its length direction, and the slider 4 is sleeved on the outside of the column 31. A pressure roller 41 is rotatably connected to the slider 4, and the pressure roller 41 is arranged parallel to the rotating wheel 32, and a clamping area is formed between the pressure roller 41 and the rotating wheel 32. The pressure roller 41 is located above the rotating wheel 32.

[0034] In order to facilitate pulling the pressure roller 41 upward, an L-shaped support rod 5 is fixedly connected to the side wall of the column 31, and the upper end of the support rod 5 is rotatably connected to a pulley 51. One end of the pull rope 52 is fixedly connected to the slider 4, and the other end naturally droops after passing around the pulley 51. The height of the pulley 51 is higher than the height of the column 31.

[0035] When the pull rope 52 is pulled down, the slider 4 can be moved upward, and at the same time, the pressure roller 41 can be moved upward synchronously with the slider 4 .

[0036] A cover plate 6 is hingedly connected to the tank body 1 . A plurality of air holes 61 are formed on the cover plate 6 . The air holes 61 are communicated with the opening 11 .

[0037] A dehydration hole 71 is provided on the side wall of the dehydration barrel 7, and the extension line of the axis of the dehydration hole 71 passes through the axis of the dehydration barrel 7. A support rod 72 is fixedly connected to the inner wall of the dehydration barrel 7, and the support rod 72 is arranged in an L shape, including a fixed section 721 and a support section 722. Among them, one end of the fixed section 721 is fixedly connected to the inner wall of the tank body 1, and the other end is fixedly connected to the side wall of the support section 722. In addition, the fixed end is located above the support section 722.

[0038] The support section 722 is hollow and one end is fixedly connected to the support ball 74. A flow hole 73 is provided on the side wall of the support section 722 and communicates with the inner wall of the support section 722. The support section 722 is coaxially arranged with the dehydration hole 71. The length of the support section 722 is 5 cm.

[0039] A plurality of communication holes 741 are provided on the support ball 74, and the plurality of communication holes 741 are arranged along the ball center of the support ball 74, and the communication holes 741 penetrate the support ball 74. The projection of the support ball 74 on the inner wall of the dehydration barrel 7 is located inside the dehydration hole 71, that is, the ball diameter of the support ball 74 is smaller than the diameter of the dehydration hole 71.

[0040] A drainage hole 81 is provided on the side wall of the lower edge of the tank body 1. The end of the drainage hole 81 away from the tank body 1 is connected to a square water tank 9 through a water pipe 82. A filter screen 91 is fixedly connected to the end of the water tank 9 near the drainage hole 81. The mesh number of the filter screen 91 is 50 meshes.

During this period, the servo motor 21 is started, and the support shaft 2 rotates slowly so that the cloth can be evenly laid in the dewatering barrel 7. The cover plate 6 is placed on the tank body 1 and is located above the opening 11. The servo motor 21 is turned on, and the support shaft 2 rotates at a high speed. The cloth moves toward the inner wall of the dewatering barrel 7 due to the centrifugal force. Due to the supporting effect of the support ball 74, the cloth is prevented from blocking the dewatering hole 71. The water in the cloth can be injected into the tank body 1 through the dewatering hole 71 to achieve rapid dehydration. The water moves down along the inner wall of the tank body 1 due to gravity and is discharged from the drainage hole 81, and then flows into the water storage tank 9. Through the filtering effect of the filter net 91, some impurities are filtered out, and then the water overflows the partition 92 and falls into the reuse water area 95. As the amount of water in the reuse water area 95 increases, the water flows into the dyeing machine from the return pipe 93 to achieve the effect of saving water.

[0042] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementations. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
