Detailed Embodiments
[0042] Embodiment 1
[0043] As Figure 1-6 shown, a non-woven fabric hydrophilization treatment device proposed by the present utility model includes a water tank 1, a feeding roller 2, a limiting roller 3, a feeding assembly 4, an overflow pipe 5, a discharging roller 6, a squeezing assembly 7 and a guide plate 8;
[0044] The number of the limiting rollers 3 is at least one. The limiting rollers 3 are rotatably installed inside the water tank 1 and near the bottom end to limit the position of the non-woven fabric inside the water tank 1 in the use state, so that the non-woven fabric moves through the hydrophilizing agent contained inside the water tank 1;
[0045] The feeding roller 2 and the discharging roller 6 are installed on the water tank 1 and are located on both sides of the top end of the water tank 1 to convey the non-woven fabric into the water tank 1 inside and convey the non-woven fabric inside the water tank 1 to the outside in the use state;
[0046] The feeding assembly 4 is installed on both sides inside the water tank 1 and extends to the outside of the water tank 1, and the end of the feeding assembly 4 faces the bottom end of the water tank 1 to communicate with an external conveying device in the use state to convey the hydrophilizing agent to the bottom end of the water tank 1;
[0047] The guide plate 8 is installed inside the water tank 1 and is located below the limiting roller 3 to guide the hydrophilizing agent conveyed by the feeding assembly 4 to the non-woven fabric in the use state; wherein, both ends of the top end of the guide plate 8 have guide grooves to move the hydrophilizing agent discharged downward by the feeding assembly 4 upward in the use state, so that the hydrophilizing agent inside the water tank 1 rolls, avoiding the precipitation of the hydrophilizing agent during use.
[0048] The squeezing assembly 7 is arranged above the discharging roller 6 to squeeze the discharging roller 6 in the use state to discharge the excess hydrophilizing agent in the non-woven fabric to the outside in the use state.
[0049] The overflow pipe 5 is installed on the side of the water tank 1 near the top end and is communicated with the water tank 1 to communicate with an external storage device to discharge and collect the excess hydrophilizing agent inside the water tank 1 to avoid the situation of overflow of the hydrophilizing agent inside the water tank 1 due to too much hydrophilizing agent.
[0050] In this embodiment, the feeding assembly 4 is connected to a water pump to convey the hydrophilizing agent with pressure to the inner side of the water tank 1, so that a part of the hydrophilizing agent fills the inner side of the water tank 1. The non-woven fabric is moved from above the feeding roller 2 to below the limiting roller 3 on the inner side of the water tank 1 and then from below the limiting roller 3 to above the discharging roller 6, so that the non-woven fabric is impregnated in the hydrophilizing agent. During the movement of the non-woven fabric, the feeding assembly 4 continuously conveys the hydrophilizing agent to the flow guiding plate 8 and impacts the flow guiding plate 8, causing the hydrophilizing agent on the inner side of the water tank 1 to flow, avoiding precipitation during use. At the same time, the hydrophilizing agent moves towards the non-woven fabric through the guiding of the flow guiding plate 8, impacting the non-woven fabric, enabling the hydrophilizing agent to quickly fuse with the non-woven fabric, thereby improving the fusion effect of the hydrophilizing agent and the non-woven fabric, increasing the impregnation efficiency of the non-woven fabric, and extruding the discharging roller 6 through the extrusion assembly 7, so that the non-woven fabric moving on the discharging roller 6 is extruded, discharging the excess hydrophilizing agent in the non-woven fabric to the outside, improving the drying effect and efficiency.
[0051] Embodiment 2
[0052] As Figure 5-6 shown, a non-woven fabric hydrophilizing treatment device proposed by the present utility model. Compared with Embodiment 1, in this embodiment, the feeding assembly 4 includes a main pipe 41, a branch pipe 42 and a shunt pipe 43;
[0053] The branch pipe 42 is installed on the water tank 1 and has at least three ends. Among them, two ends are respectively installed on both sides of the water tank 1 and extend to the inner side of the water tank 1 for conveying the hydrophilizing agent to the inner side of the water tank 1 in the use state;
[0054] The number of the shunt pipes 43 is two, both located inside the water tank 1 and installed at the ends of the branch pipe 42, and a plurality of discharge ports are arranged on the side facing the bottom end of the water tank 1 for conveying the hydrophilizing agent to the bottom end of the water tank 1 in the use state and tumbling the hydrophilizing agent inside the water tank 1 during conveyance, avoiding the situation of hydrophilizing agent precipitation;
[0055] The main pipe 41 is installed at the third end of the branch pipe 42 for communicating with an external conveying device to convey the hydrophilizing agent to the branch pipe 42.
[0056] In an optional embodiment, discharge pipes 44 are provided at multiple discharge ports of the shunt pipe 43. The inner diameter value of the discharge pipe 44 gradually decreases from the discharge port of the limiting roller 3 towards the flow guiding plate 8 along the discharge port direction of the limiting roller 3, and the inner diameter of the main pipe 41 is larger than the inner diameter of the branch pipe 42 for enabling the hydrophilizing agent conveyed to the inner side of the water tank 1 to have a certain pressure in the use state, so that it impacts the non-woven fabric along the flow guiding plate 8, improving the combination efficiency of the non-woven fabric and the hydrophilizing agent, reducing the area of the non-woven fabric inside the water tank 1, and thus reducing the number of limiting rollers 3 used.
[0057] In this embodiment, the main pipe 41 is connected to a water pump to convey the hydrophilizing agent to the branch pipe 42. During the conveying process, the pipe diameter decreases, resulting in an increase in the inner pressure of the branch pipe 42. This causes the hydrophilizing agent inside the branch pipe 42 to move towards the shunt pipe 43 under pressure and be shunted, so that the discharge area of the hydrophilizing agent conveyed by the branch pipe 42 matches the width of the water tank 1. At the same time, when the shunt pipe 43 discharges, the discharge pressure is further increased through the discharge pipe 44, enabling the hydrophilizing agent to be added to the inside of the water tank 1 with an impact force. Under the guidance of the baffle plate 8, it contacts the non-woven fabric, accelerating the fusion of the non-woven fabric and the hydrophilizing agent. At the same time, it drives the hydrophilizing agent at the bottom end inside the water tank 1 to move upward, causing the hydrophilizing agent inside the water tank 1 to roll, thus preventing the hydrophilizing agent from precipitating.
[0058] Embodiment Three
[0059] As Figure 4 shown, a non-woven fabric hydrophilization treatment device proposed by the present utility model. Compared with Embodiment One, in this embodiment, the extrusion assembly 7 includes a downward pressure structure 71, a mounting frame 72, and a limiting structure 73;
[0060] The mounting frame 72 is arranged above the discharging roller 6 and is connected to the bearing seat of the discharging roller 6 or directly to the top end of the water tank 1;
[0061] The downward pressure structure 71 is slidably installed inside the mounting frame 72 and is used to extrude the non-woven fabric on the discharging roller 6 by its own gravity in the working state. When the non-woven fabric moves on the discharging roller 6, the downward pressure structure 71 rolls to extrude the excess hydrophilizing agent in the non-woven fabric, preventing too much hydrophilizing agent from affecting the subsequent process;
[0062] The limiting structure 73 is arranged at the middle part of the top end of the mounting frame 72 and extends to the inside of the mounting frame 72 to contact the downward pressure structure 71, and is used to limit the position of the downward pressure structure 71 in the working state, preventing the situation that the gravity of the downward pressure structure 71 is too small to discharge the excess hydrophilizing agent in the non-woven fabric.
[0063] In an optional embodiment, the downward pressure structure 71 includes a slider 711, a mounting plate 712, and a pressure roller 713;
[0064] The mounting plate 712 is arranged inside the mounting frame 72, and its shape is U-shaped, and both sides are provided with bearings for supporting the pressure roller 713 during use;
[0065] There are two sliders 711, and the two sliders 711 are respectively installed at one end of the mounting plate 712 and are slidably connected to the mounting frame 72. Among them, chutes are provided on both inner sides of the mounting frame 72. In the state where the pressing structure 71 is cooperatively installed with the mounting frame 72, the sliders 711 are cooperatively received inside the chutes of the mounting frame 72 to vertically move the mounting plate 712 through the cooperation between the sliders 711 and the chutes of the mounting frame 72 in the use state. The chutes of the mounting frame 72 are L-shaped to separate the pressing structure 71 from the mounting frame 72 in the use state, so as to perform operations such as replacement and maintenance of the pressing structure 71.
[0066] The pressure roller 713 is rotatably installed inside the mounting plate 712 to rotate following the movement of the non-woven fabric in the use state, so that the pressure roller 713 rolls the non-woven fabric on the discharge roller 6 to avoid the non-woven fabric having excess hydrophilizing agent and moving to the next process.
[0067] In this embodiment, the mounting plate 712 is installed inside the mounting frame 72 through the cooperation between the sliders 711 and the chutes of the mounting frame 72, and vertically moves along the chutes of the mounting frame 72, so that the pressing structure 71 slides towards the discharge roller 6 by its own gravity and rolls the non-woven fabric during the conveying process of the non-woven fabric, discharging the excess hydrophilizing agent in the non-woven fabric. At the same time, the upward movement distance of the pressing structure 71 is limited by the limiting structure 73 to prevent the pressing structure 71 from being unable to discharge the excess hydrophilizing agent from the non-woven fabric by its own gravity.
[0068] Embodiment Four
[0069] As Figure 4 shown, a non-woven fabric hydrophilization treatment device proposed by the present utility model. Compared with Embodiment Three, in this embodiment, the limiting structure 73 includes a nut 731 and a screw 732.
[0070] The nut 731 is installed in the middle of the top end of the mounting frame 72.
[0071] The screw 732 is inserted into the middle of the nut 731 and extends to the inside of the mounting frame 72 to limit the position of the pressing structure 71 by moving inside the nut 731 in the use state.
[0072] In this embodiment, the screw 732 is turned to adjust the length of the bottom end of the screw 732 located inside the mounting frame 72, so as to limit the upward movement distance of the pressing structure 71 inside the mounting frame 72 and improve the stability of the pressing structure 71 in working on the non-woven fabric.
[0073] In summary, when the utility model is in use, the feeding assembly 4 is connected to a water pump to convey the hydrophilizing agent with pressure to the inner side of the water tank 1, so that part of the hydrophilizing agent is filled in the inner side of the water tank 1. The non-woven fabric is moved from above the feeding roller 2 to below the limiting roller 3 in the inner side of the water tank 1, and then from below the limiting roller 3 to above the discharging roller 6, so that the non-woven fabric is impregnated in the hydrophilizing agent. During the movement of the non-woven fabric, the hydrophilizing agent is conveyed to the branch pipe 42 through the main pipe 41. During the conveying process, the change in the pipe diameter size causes the pressure inside the branch pipe 42 to increase, so that the branch pipe 42 conveys the hydrophilizing agent with pressure to the shunt pipe 43, and is shunted through multiple discharging ports of the shunt pipe 43, so that the branch pipe 42 conveys the hydrophilizing agent to a large area inside the water tank 1. At the same time, the structure of the discharging pipe 44 further increases the discharging pressure, so that the hydrophilizing agent is added to the inner side of the water tank 1 with impact force, and contacts the non-woven fabric under the diversion of the diversion plate 8, accelerating the fusion of the non-woven fabric and the hydrophilizing agent, and at the same time driving the hydrophilizing agent at the bottom end inside the water tank 1 to move upward, causing the hydrophilizing agent inside the water tank 1 to roll, avoiding the precipitation of the hydrophilizing agent. The mounting plate 712 is installed inside the mounting frame 72 through the cooperation of the slider 711 and the chute of the mounting frame 72, and moves vertically along the chute of the mounting frame 72, so that the pressing structure 71 slides towards the discharging roller 6 by its own gravity, and the pressing structure 71 rolls the non-woven fabric moving on the discharging roller 6 by its own weight. At the same time, the screw 732 is rotated to adjust the length of the bottom end of the screw 732 located inside the mounting frame 72, so as to limit the upward movement distance of the pressing structure 71 inside the mounting frame 72, discharge the excess hydrophilizing agent in the non-woven fabric, and avoid the situation that the pressing structure 71 cannot discharge the excess hydrophilizing agent from the non-woven fabric by its own gravity, and avoid the situation that the pressing structure 71 cannot discharge the hydrophilizing agent from the non-woven fabric by its own weight, improving the stability of the pressing structure 71 in working on the non-woven fabric.
[0074] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited thereto. Various changes can be made without departing from the gist of the present utility model within the scope of knowledge possessed by those skilled in the art to which the present utility model pertains.
