[0002] Spraying devices are indispensable key equipment in the production of tissue paper, running through multiple core processes. They not only solve problems such as drying and dust in production, but also enable product function upgrades. Different types of spraying devices are suitable for different processes and have different focuses. In the rewinding and slitting process, ultrasonic and high-pressure micro-mist humidifiers are used. After the paper is dried, the moisture content is low, and dust is easily generated during rewinding and slitting. It is also easy for impurities to be attracted by static electricity. For example, the humidifier of Zhengdao ZS-20 tissue paper rewinding machine adopts the principle of ultrasonic high-frequency oscillation. The spray particles are fine and the humidification is uniform. It can increase the air humidity through spraying, reduce the dust formed by the shedding of paper fibers, and eliminate static electricity to prevent paper dust from adhering to the paper surface.

[0003] Regarding the above-mentioned technical solutions, the existing spraying devices do not have good reinforcement functions. During the spraying process, the pipe shaking will affect the uniformity of the spray. In addition, they do not have good centering functions, and they are prone to deviation during the winding process, which will affect the quality of the product.

[0004] Therefore, this utility model provides a spraying device for the production of household paper to solve the above problems. Utility Model Content

[0025] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] Reference Figures 1 to 4This application provides a spraying device for use in the production of household paper, including a base plate 1. A spraying assembly 2 is fixedly installed on the top of the base plate 1. The spraying assembly 2 includes a water tank 21 and a water pump 22. The water tank 21 is fixedly installed on the top of the base plate 1, and the water pump 22 is fixedly installed on the top of the water tank 21. The input end of the water pump 22 is fixedly connected to the water tank 21, and the output end of the water pump 22 is fixedly connected to a connecting pipe 23. An arc-shaped plate 35 and an arc-shaped plate 33 are respectively engaged with the connecting pipe 23. One end of the connecting pipe 23 is fixedly connected to an atomizing nozzle 24. A control panel 5 is electrically connected to the water pump 22. A stabilizing component 3 is fixedly installed on the side of the spraying assembly 2, and the control panel 5 is fixedly installed on one side of the spraying assembly 2. A conveying assembly 6 is fixedly installed on the top of the base plate 1, and a centering assembly 7 is fixedly installed on one side of the spray assembly 2. The stabilizing assembly 3 includes a positioning frame 31 and a rectangular plate 32. The positioning frame 31 is fixedly installed on one side of the spray assembly 2, and the rectangular plate 32 is snapped onto one side of the positioning frame 31. An arc-shaped plate 33 is fixedly installed on the top of the rectangular plate 32. A rectangular plate 34 is snapped onto the other side of the positioning frame 31, and an arc-shaped plate 35 is fixedly installed on the top of the rectangular plate 34. A bolt 36 is threadedly connected to one side of the rectangular plate 32. The bolt 36 is threadedly connected to the positioning frame 31 and the rectangular plate 34 respectively. A nut 4 is threadedly connected to the side wall of the bolt 36, and the nut 4 is located on one side of the rectangular plate 34.

[0027] In this embodiment, the control panel 5 controls the operation of the spray assembly 2. The water pump 22 draws liquid from the water tank 21 and delivers it to the atomizing nozzle 24 through the connecting pipe 23. The atomizing nozzle 24 atomizes the liquid and sprays it onto the conveyed tissue paper. During this process, the stabilizing assembly 3 ensures the stability of the spray pipeline. The positioning frame 31 clamps and positions the connecting pipe 23 through rectangular plate 32, rectangular plate 34, and arc plate 33 and arc plate 35. The bolts 36 are tightened and locked with nuts 4, so that rectangular plate 32 and rectangular plate 35 fit tightly against the positioning frame 31, preventing the connecting pipe 23 from shifting during liquid delivery and equipment operation. This ensures that the spray range of the atomizing nozzle 24 accurately covers the paper, achieving stable and uniform spray treatment. The control panel 5 is a Siemens S7-200SMARTCPUSR40, the water pump 22 is a Watson Marlowe Qdos30, and the motor 62 is a three-phase asynchronous motor Y100L-4.

[0028] Reference Figures 1 to 4In one aspect of this embodiment, the conveying assembly 6 includes a first fixing frame 61 and a motor 62. The first fixing frame 61 is fixedly installed on the top of the base plate 1, and the motor 62 is fixedly installed on one side of the first fixing frame 61. The output end of the motor 62 is fixedly connected to a drive roller 63. The control panel 5 is electrically connected to the motor 62. The conveying assembly 6 also includes a second fixing frame 64 and a rotating roller 65. The second fixing frame 64 is fixedly installed on the top of the spraying assembly 2, and the rotating roller 65 is connected to the inner side wall of the second fixing frame 64 through a bearing. The centering assembly 7 includes a fixing plate 71 and a screw 72. The fixing plate 71 is fixedly installed on one side of the spraying assembly 2, and the screw 72 is connected to the top of the fixing plate 71 through a bearing. A lifting block 73 is threadedly connected to the side wall of the screw 72. Connecting rods 74 are hinged to both sides of the lifting block 73, and a centering plate 75 is hinged to one end of the connecting rod 74. The centering plate 75 is slidably connected to the fixing plate 71. The centering assembly 7 also includes a knob 76, which is fixedly connected to the top end of the screw 72.

[0029] In this embodiment, rotating the knob 76 drives the screw 72 to rotate, and the screw 72 drives the lifting block 73 to move up and down. The lifting block 73 pulls the centering plate 75 along the fixed plate 71 through the connecting rods 74 on both sides until the distance between the two centering plates 75 matches the width of the paper, thus completing the centering calibration. After starting, the control panel 5 controls the operation of the conveying assembly 6, and the motor 62 drives the drive roller 63 to rotate, forming a conveying channel with the rotating roller 65 on the second fixed frame 64. The tissue paper is smoothly conveyed forward under the synergistic action of the drive roller 63 and the rotating roller 65, providing a stable material conveying foundation for subsequent spraying operations. In this case, the thread helix angle is less than or equal to the equivalent friction angle.

[0030] Working principle: Rotating the knob 76 drives the screw 72 to rotate, and the screw 72 drives the lifting block 73 to move up and down. The lifting block 73 pulls the centering plate 75 along the fixed plate 71 through the connecting rods 74 on both sides until the distance between the two centering plates 75 matches the width of the paper, completing the centering calibration. After starting, the control panel 5 controls the operation of the conveying component 6, and the motor 62 drives the drive roller 63 to rotate, which, together with the rotating roller 65 on the second fixed frame 64, forms a conveying channel. The tissue paper is smoothly conveyed forward under the synergistic action of the drive roller 63 and the rotating roller 65, providing a stable material conveying foundation for subsequent spraying operations.

[0031] Control panel 5 controls the operation of spray assembly 2. Water pump 22 draws liquid from water tank 21 and delivers it to atomizing nozzle 24 via connecting pipe 23. Atomizing nozzle 24 atomizes the liquid and sprays it onto the conveying tissue paper. During this process, stabilizing assembly 3 ensures the stability of the spray pipeline. Positioning frame 31 clamps and positions connecting pipe 23 using rectangular plate 1 32, rectangular plate 2 34, and arc plate 1 33 and arc plate 2 35. Tightening bolt 36 and locking it with nut 4 ensures that rectangular plate 1 32 and rectangular plate 2 35 are tightly fitted to positioning frame 31, preventing displacement of connecting pipe 23 during liquid delivery and equipment operation. This ensures that the spray range of atomizing nozzle 24 accurately covers the paper, achieving stable and uniform spray treatment.
