Description

Technical Field

[0001] This utility model relates to the field of wet wipe production equipment, and in particular to a spraying device for antibacterial wet wipes. Background Technology

[0002] Wet wipes are a common cleaning product. Because they contain moisture, antibacterial agents, and cleaning agents, they can effectively replace towels when water is unavailable. Their convenience has led to their increasingly widespread use. The disinfecting and antibacterial ingredients in existing wet wipes are typically chemical agents such as ethanol, iodine, peracetic acid, and bleaching powder. These liquids, containing disinfecting and antibacterial agents, need to be sprayed onto a substrate using a spraying device to give the wipes their antibacterial properties.

[0003] However, during the production process, some of the disinfectant components are prone to precipitate or volatilize in the storage tank, affecting the stability of the concentration. Furthermore, traditional spraying equipment is difficult to evenly cover the substrate, resulting in uneven distribution of the antibacterial agent and affecting the antibacterial effect. Utility Model Content

[0004] Therefore, in view of the above problems, this utility model provides a spraying device for antibacterial wipes that can accurately control the amount of antibacterial agent sprayed and improve uniformity and stability.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A spraying device for antibacterial wipes includes a frame, a control system, a substrate conveying mechanism, a storage tank, a water inlet pipe, a dosing pipe, a dosing mechanism, a water outlet pipe, a drive motor, a stirring shaft, stirring blades, a water distribution plate, at least two hoses, a hydraulic pump, and at least two spraying mechanisms. The substrate conveying mechanism is mounted on the frame and is used for continuous conveying of the substrate. The longitudinal direction of the substrate conveying mechanism is defined as its conveying direction, and the transverse direction is defined as its width direction. The storage tank has a storage cavity. The stirring shaft is rotatably mounted on the storage tank. The drive motor is connected to the upper end of the stirring shaft. The stirring blades are mounted on the stirring shaft and located within the storage cavity. The storage tank has a water distribution plate. The water inlet, dosing port, and outlet are connected to the liquid storage chamber. The water inlet pipe is connected to the water inlet. The dosing mechanism is connected to the dosing port through the dosing pipe. The water distribution plate has one water inlet and at least two water outlets. The water inlet of the water distribution plate is connected to the water outlet through a hydraulic pump and a water outlet pipe. Each water outlet of the water distribution plate is connected to a spraying mechanism through a hose. Each spraying mechanism is spaced apart along the longitudinal direction of the substrate conveying mechanism. Each spraying mechanism includes a base fixed on the frame, a connector on the base, and a spraying pipe detachably connected to the base. The central axis of the spraying pipe is distributed in the transverse direction. At least three nozzles are spaced apart along the transverse direction on the spraying pipe.

[0007] Furthermore, the spray pipe includes an inner pipe, an outer pipe, a sealing ring, an end cap, and a rotating paddle. One lateral end of the outer pipe is threaded to the base. The inner pipe passes through the outer pipe via the sealing ring. The end cap covers the other lateral end of the inner pipe. A strip groove is formed on the outer pipe at the nozzle. Each strip groove is distributed along the circumferential direction of the outer pipe. The paddle is connected to the inner pipe.

[0008] Furthermore, the tilt angle of the nozzle is adjustable from 30° to 60°.

[0009] Furthermore, the water distribution plate has a water distribution cavity, and the water distribution cavity is provided with a first water guide plate and a second water guide plate with an arc-shaped structure. One lateral end of the first water guide plate is fixed to the inner side wall of the water distribution plate, and the convex surface of the first water guide plate faces the water inlet end. The other lateral end of the second water guide plate is fixed to the inner side wall of the water distribution plate, and the convex surface of the second water guide plate faces the water outlet end.

[0010] Furthermore, the control system includes a controller, an upper liquid level sensor located at the top of the liquid storage chamber, a lower liquid level sensor located at the bottom of the liquid storage chamber, and a pressure sensor located on the spray pipe. The upper liquid level sensor, the lower liquid level sensor, and the pressure sensor are electrically connected to the input terminal of the controller, and the hydraulic pump, the drive motor, and the dosing mechanism are electrically connected to the output terminal of the controller.

[0011] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows: The spraying device of this antibacterial wipes, through the drive motor driving the stirring shaft and stirring blades, realizes the dynamic mixing of antibacterial agent and solvent, avoids sedimentation and stratification, and ensures the stability of solution concentration. The water distribution plate evenly distributes the liquid to each spraying pipe, and with the multiple spraying mechanisms distributed longitudinally at intervals, it expands the lateral coverage range and solves the uniformity problem of traditional single-point spraying. The spraying pipe and the base are detachably connected, which facilitates quick replacement or cleaning of the spray head, reduces downtime maintenance time, and improves the continuity of the production line. At least three spray heads are arranged laterally on a single spraying pipe to form a dense spray network, ensuring the uniformity of antibacterial agent coverage in the width direction of the substrate.

[0018] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0019] The embodiment of this utility model is as follows:

[0020] refer to Figures 1 to 6 As shown, a spraying device for antibacterial wipes includes a frame, a control system 1, a substrate conveying mechanism 2, a storage tank 3, a water inlet pipe 4, a dosing pipe 5, a dosing mechanism 6, a water outlet pipe 7, a drive motor 8, a stirring shaft 9, stirring blades 10, a water distribution plate 11, three flexible hoses 12, a hydraulic pump 13, and two spraying mechanisms 14. The substrate conveying mechanism 2 is mounted on the frame and is used for continuous conveying of the substrate. The longitudinal direction is defined as the direction along which the substrate conveying mechanism 2 is conveyed, and the transverse direction is defined as the direction along which the substrate conveying mechanism 2 is wide. The storage tank 3 has a storage cavity 30. The stirring shaft 9 is rotatably mounted on the storage tank 3. The drive motor 8 is connected to the upper end of the stirring shaft 9. The stirring blades 10 are mounted on the stirring shaft 9 and located within the storage cavity 30. The storage tank 3 has water inlets that communicate with the storage cavity 30. The system includes an inlet 31, a dosing port 32, and an outlet 33. The inlet pipe 4 is connected to the inlet 31. The dosing mechanism 6 is connected to the dosing port 32 via a dosing pipe 5. The water distribution plate 11 has one inlet end 111 and two outlet ends 112. The inlet end 111 of the water distribution plate 11 is connected to the outlet 33 via a hydraulic pump 13 and an outlet pipe 7. Each outlet end 112 of the water distribution plate 11 is connected to each spraying mechanism 14 via a hose 12. Each spraying mechanism 14 is spaced apart along the longitudinal direction of the substrate conveying mechanism 2. Each spraying mechanism 14 includes a base 141 fixed on the frame, a connector 142 on the base 141, and a spray pipe detachably connected to the base 141. The central axis of the spray pipe is distributed in the transverse direction, and three nozzles 143 are spaced apart along the transverse direction on the spray pipe.

[0021] The spray device of this antibacterial wipe uses a drive motor 8 to drive a stirring shaft 9 and stirring blades 10 to achieve dynamic mixing of the antibacterial agent and solvent, avoiding sedimentation and stratification, and ensuring the stability of the solution concentration. The water distribution plate 11 evenly distributes the liquid to each spray pipe. In conjunction with multiple spray mechanisms 14 distributed longitudinally at intervals, the lateral coverage range is expanded, solving the uniformity problem of traditional single-point spraying. The spray pipes and the base 141 are detachably connected, which facilitates quick replacement or cleaning of the spray nozzles, reduces downtime for maintenance, and improves the continuity of the production line. At least three spray nozzles 143 are arranged laterally on a single spray pipe to form a dense spray network, ensuring uniform coverage of the antibacterial agent in the width direction of the substrate.

[0022] Specifically, the spray pipe includes an inner pipe 144, an outer pipe 145, a sealing ring 146, an end cap 147, and a rotating lever 148. One lateral end of the outer pipe 145 is threadedly connected to the base 141. The inner pipe 144 passes through the outer pipe 145 via the sealing ring 146. The end cap 147 covers the other lateral end of the inner pipe 144. A strip groove 149 is formed on the outer pipe 145 at the nozzle 143, and each of the strip grooves 149 is distributed along the circumferential direction of the outer pipe 145. The lever 148 is connected to the inner pipe 144. The tilt angle of the nozzle 143 is adjustable from 30° to 60°, preferably 35°. The inner pipe 144 and the outer pipe 145... 5. The sealing ring 146 prevents liquid leakage and allows the inner tube 144 to rotate to adjust the angle of the nozzle 143, adapting to the penetration requirements of different substrates. When the inner tube 144 is rotated, the paddle 148 causes liquid disturbance, which, combined with the guide of the strip groove 149, enhances the spray diffusion effect and reduces the risk of substrate damage caused by local liquid accumulation. The outer tube 145 is threaded to the base 141, simplifying the disassembly and assembly process, facilitating the cleaning of impurities inside the nozzle 143, reducing the probability of clogging, improving spray stability, and the 30° to 60° tilt angle adjustment range is suitable for different substrate thicknesses, such as single-layer non-woven fabric or multi-layer composite. By changing the incident angle, the liquid penetration depth can be controlled, avoiding waste caused by excessive spraying.

[0023] Furthermore, the water distribution plate 11 has a water distribution cavity 113, and the water distribution cavity 113 is provided with a first water guide plate 114 and a second water guide plate 115 with an arc-shaped structure. One lateral end of the first water guide plate 114 is fixed to the inner side wall of the water distribution plate 11, and the convex surface of the first water guide plate 114 faces the water inlet end. The other lateral end of the second water guide plate 115 is fixed to the inner side wall of the water distribution plate 11, and the convex surface of the second water guide plate 115 faces the water outlet end. The arc-shaped structure of the first water guide plate 114 and the second water guide plate 115 guides the liquid to turn smoothly, reduces the generation of eddies in the water distribution cavity 113, ensures the pressure balance at each water outlet end, and avoids the spray volume deviation caused by pressure fluctuation. The two water guide plates are arranged facing the water inlet end and the water outlet end respectively, forming a symmetrical flow distribution path, further reducing the turbulence inside the water distribution plate 11 and improving the flow consistency among the multiple spray mechanisms 14.

[0024] In this embodiment, the control system 1 includes a controller 101, an upper liquid level sensor 102 located on the upper part of the liquid storage chamber 30, a lower liquid level sensor 103 located on the lower part of the liquid storage chamber 30, and a pressure sensor 104 located on the spray pipe. The upper liquid level sensor 102, the lower liquid level sensor 103, and the pressure sensor 104 are electrically connected to the input terminal of the controller 101, and the hydraulic pump 13, the drive motor 8, and the dosing mechanism 6 are electrically connected to the output terminal of the controller 101. The upper liquid level sensor 102 and the lower liquid level sensor 103 monitor the liquid storage volume in real time, and the pressure sensor 104 provides feedback on the spray pressure. The controller 101 dynamically adjusts the output of the dosing mechanism 6 and the hydraulic pump 13 to achieve precise control of the antibacterial agent concentration and spray volume. The dual liquid level sensors work together to control the dosing and water intake, preventing the liquid storage tank 3 from overflowing or the pump from running dry and being damaged due to excessively low liquid level, thus ensuring the stability and safety of the equipment operation.
