Description

Technical Field

[0001] This utility model relates to the field of disposable hygiene product production equipment, and in particular to an antibacterial wet wipe liquid dispensing device. Background Technology

[0002] With the development of good hygiene habits and the improvement of living standards, wet wipes have gradually become a necessity in people's daily lives. The main raw materials for the production of wet wipes are non-woven fabric and wet wipe liquid. By spraying wet wipe liquid onto non-woven fabric and adding antibacterial agents and other ingredients to the non-woven fabric, wet wipes can have antibacterial properties.

[0003] Existing wet wipe dispensing devices, such as the one disclosed in Chinese Patent Application No. 202020689834.9, include a conveyor belt and wet wipes placed on the conveyor belt. A first dispensing group, a second dispensing group, and a first fixed support are installed on one side of the conveyor belt, and a second fixed support is installed on the other side. The first dispensing group is connected to the first fixed support via a pipe, and the second dispensing group is connected to the second fixed support via a pipe. Both the first and second dispensing groups consist of four or more identical dispensing pipes. Each dispensing pipe includes an inlet pipe, a regulating valve, a conduit, a storage tank, and a dispensing pipe connected in sequence. The dispensing pipe has a dispensing hole. The dispensing pipe of the first dispensing group is parallel to the wet wipe, and the angle γ between the dispensing pipe and the outer edge of the wet wipe is 45° to 60°. The dispensing pipe of the second dispensing group is parallel to the wet wipe, and the angle δ between the dispensing pipe and the outer edge of the wet wipe is -45° to 60°.

[0004] The aforementioned wet wipe liquid dispensing device uses dispensing tubes of the first and second dispensing groups arranged parallel to the wet wipes, with the angle between the dispensing tubes and the outer edge of the wet wipes designed to improve the uniformity of liquid dispensing to some extent. However, due to the difference in the angles between the dispensing tubes of the first and second dispensing groups and the outer edge of the wet wipes, it was found in actual use that some of the wet wipe liquid was not sprayed onto the non-woven fabric, and some areas that were sprayed onto the non-woven fabric were sprayed repeatedly, resulting in uneven distribution of the wet wipe liquid and insufficient antibacterial agent content in some wet wipes. Utility Model Content

[0005] Therefore, in view of the above problems, this utility model provides an antibacterial wet wipe liquid dispensing device, which mainly solves the problem that the poor spray uniformity of the wet wipe liquid dispensing device in the prior art leads to insufficient antibacterial agent content in some wet wipes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An antibacterial wipe liquid dispensing device includes a frame, a control system, a conveying mechanism, a liquid storage tank, an inlet pipe, an outlet pipe, a replenishment pipe, a first water pump, a second water pump, a third water pump, a liquid storage tank, a spraying mechanism, a humidifying roller, and a pressing mechanism. The conveying mechanism includes a driving roller, a driven roller, and a conveying screen wound around the driving and driven rollers. The conveying screen has a conveying surface for conveying non-woven fabric. The liquid storage tank is located below the conveying surface. The humidifying roller is rotatably mounted on the liquid storage tank, with its upper end abutting against the conveying screen. A first liquid level sensor is installed inside the liquid storage tank. The liquid storage tank has an inlet, an outlet, and a replenishment port. The storage tank is connected to the inlet of the storage tank via an inlet pipe. The first water pump is installed on the inlet pipe. The replenishment pipe is connected to the replenishment port of the storage tank. The second water pump is installed on the replenishment pipe. The spraying mechanism is connected to the outlet of the storage tank via an outlet pipe. A second liquid level sensor is installed inside the storage tank. The third water pump is installed on the outlet pipe. The spraying mechanism has several arrayed multi-hole diversion nozzles, each distributed on the upper side of the conveying surface. The pressure mechanism is installed at the output end of the conveying mechanism. The first liquid level sensor, the second liquid level sensor, the first water pump, the second water pump, and the third water pump are electrically connected to the control system.

[0008] Furthermore, the nozzle includes a mounting base, a connector, a connecting base, a nozzle body, and a nozzle cover. The connector is located at one end of the mounting base, and the connecting base is located at the other end of the mounting base. The connecting base has an opening. The mounting base has a main flow channel connecting the connector and the opening, and at least two branch channels communicating with the main flow channel. The nozzle body is fitted onto the connecting base. The nozzle body has 15 to 24 nozzles with a diameter of 0.3 to 0.5 mm ± 0.02 mm formed by laser micromachining. Each nozzle is communicating with the main flow channel. The nozzle cover is located on the connecting base and covers the periphery of the nozzle body. A gap is formed between the nozzle cover and the nozzle body. Each branch channel is communicating with the gap.

[0009] Furthermore, the connecting seat includes a first part with a cylindrical structure and a second part with a spherical structure, the second part being located at one axial end of the first part, and the diameter of the second part being larger than the diameter of the first part.

[0010] Furthermore, the humidifying roller has matrix-distributed recesses on its circumferential surface, and the cross-section of each recess is trapezoidal.

[0011] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows: The antibacterial wet wipe liquid dispensing device employs an active roller, a driven roller, and a conveying screen in its conveying mechanism, ensuring stable conveying of the non-woven fabric. The liquid storage tank cooperates with the conveying surface, and the humidifying roller abuts against the conveying screen, allowing the non-woven fabric to initially and evenly absorb the wet wipe liquid. The multi-hole diversion nozzles of the spraying mechanism are arrayed on the upper side of the conveying surface, enabling all-around and even spraying of the wet wipe liquid. The liquid pressing mechanism can press the liquid onto the non-woven fabric after liquid dispensing, further ensuring uniform distribution of the wet wipe liquid. Simultaneously, through the electrical connection of the first and second liquid level sensors with the control system, the liquid levels in the storage tank and reservoir can be monitored in real time. Combined with the first, second, and third water pumps, automatic liquid replenishment and stable liquid supply are achieved, ensuring the stability and uniformity of the liquid dispensing process and improving the antibacterial performance and quality of the wet wipes.

[0017] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0018] The embodiment of this utility model is as follows:

[0019] refer to Figures 1 to 5As shown, an antibacterial wipe liquid dispensing device includes a frame, a control system 1, a conveying mechanism 2, a liquid storage tank 3, an inlet pipe 4, an outlet pipe 5, a replenishment pipe 6, a first water pump 7, a second water pump 8, a third water pump 9, a liquid storage tank 10, a spraying mechanism 11, a humidifying roller 12, and a liquid pressing mechanism 13. The conveying mechanism 2 includes a driving roller 21, a driven roller 22, and a conveying screen 23 wound around the driving roller 21 and the driven roller 22. The conveying screen 23 has a conveying surface 24 for conveying non-woven fabric. The liquid storage tank 10 is located below the conveying surface 24. The humidifying roller 12 is rotatably mounted on the liquid storage tank 10, and the upper end of the humidifying roller 12 abuts against the conveying screen 23. A first liquid level sensor 14 is provided inside the liquid storage tank 10. The liquid storage tank 3 has an inlet, an outlet, and a... The liquid storage tank 10 is connected to the inlet of the liquid storage tank 3 via the inlet pipe 4. The first water pump 7 is installed on the inlet pipe 4. The liquid replenishment pipe 6 is connected to the liquid replenishment port of the liquid storage tank 3. The second water pump 8 is installed on the liquid replenishment pipe 6. The spraying mechanism 11 is connected to the outlet of the liquid storage tank 3 via the outlet pipe 5. The liquid storage tank 3 is equipped with a second liquid level sensor 15. The third water pump 9 is installed on the outlet pipe 5. The spraying mechanism 11 has a plurality of multi-hole diversion nozzles 111 arranged in an array. Each of the multi-hole diversion nozzles 111 is distributed on the upper side of the conveying surface 24. The liquid pressure mechanism 13 is installed at the output end of the conveying mechanism 2. The first liquid level sensor 14, the second liquid level sensor 15, the first water pump 7, the second water pump 8 and the third water pump 9 are electrically connected to the control system 1.

[0020] In this embodiment, the control system 1 is a commercially available PLC controller capable of performing control functions; the first liquid level sensor 14 and the second liquid level sensor 15 are commercially available sensors used to detect liquid level height.

[0021] This antibacterial wipe liquid dispensing device employs a conveying mechanism 2 consisting of an active roller 21, a driven roller 22, and a conveying screen 23, ensuring stable conveying of the non-woven fabric. The liquid storage tank 10 engages with the conveying surface 24, and the humidifying roller 12 abuts against the conveying screen 23, allowing the non-woven fabric to initially and evenly absorb the liquid. The spraying mechanism 11 features a multi-hole distribution nozzle 111 arrayed on the upper side of the conveying surface 24, enabling uniform spraying of the liquid from all directions. The pressing mechanism 13 presses the liquid onto the non-woven fabric after dispensing, further ensuring uniform liquid distribution. Simultaneously, through the first liquid level sensor 14 and the second liquid level sensor 15, which are electrically connected to the control system 1, the liquid levels in the storage tank 10 and the storage container 3 can be monitored in real time. This, combined with the first water pump 7, the second water pump 8, and the third water pump 9, enables automatic liquid replenishment and stable liquid supply, ensuring the stability and uniformity of the dispensing process and improving the antibacterial performance and quality of the wipes.

[0022] Specifically, the nozzle 111 includes a mounting base 101, a connector 102, a connecting base 103, a nozzle body 104, and a nozzle cover 105. The connector 102 is located at one end of the mounting base 101, and the connecting base 103 is located at the other end of the mounting base 101. The connecting base 103 has an opening 106. The mounting base 101 has a main channel 107 connecting the connector 102 and the opening 106, and four branch channels 108 communicating with the main channel 107. The nozzle body 104 is fitted onto the connecting base 103. The nozzle body 104 has 20 spray holes 109 with a diameter of 0.4mm ± 0.02mm formed by laser micromachining. Each spray hole 109 communicates with the main channel 107. The nozzle cover 105 is located on the connecting base 103 and covers the periphery of the nozzle body 104. A gap is formed between the nozzle cover 105 and the nozzle body 104. The spacing is 110, and each of the aforementioned diversion channels 108 is connected to the spacing 110. The main channel 107 and at least two diversion channels 108 are set through the mounting base 101, which enables the wet wipe liquid to be reasonably distributed in the nozzle 111, ensuring the uniformity of liquid supply to each spray hole 109. The nozzle body 104 is provided with 20 spray holes 109 with a diameter of 0.4mm±0.02mm formed by laser micromachining. The high precision of laser micromachining can ensure the consistency and accuracy of the size of the spray holes 109, so that the wet wipe liquid forms small and uniform droplets when sprayed, improving the uniformity of spraying. The nozzle cover 105 and the nozzle body 104 form a spacing of 110, and the diversion channels 108 are connected to the spacing 110, which allows some wet wipe liquid to flow out from the spacing 110, providing auxiliary liquid addition to the non-woven fabric around the nozzle body 104, further expanding the liquid addition range, enhancing the liquid addition uniformity, and avoiding local insufficient or excessive liquid addition.

[0023] Furthermore, the connecting seat 103 includes a first part 113 with a cylindrical structure and a second part 123 with a spherical structure. The second part 123 is located at one axial end of the first part 113, and the diameter of the second part 123 is larger than the diameter of the first part 113.

[0024] The second part 123 of the spherical structure increases the contact area with the nozzle body 104, making the nozzle body 104 more stable and reducing the shaking of the nozzle 111 during operation, thus ensuring the stability of the spray. At the same time, this special structure can change the flow direction and distribution of the wet wipe liquid, allowing the wet wipe liquid to flow and split more smoothly in the nozzle 111, further improving the uniformity of the wet wipe liquid sprayed from the nozzle 109, and helping to improve the overall effect of wet wipe liquid addition.

[0025] Furthermore, the humidifying roller 12 has matrix-distributed recesses 16 on its circumferential surface. Each recess 16 has a trapezoidal cross-section. The matrix distribution of the recesses 16 increases the liquid storage capacity of the humidifying roller 12, allowing the nonwoven fabric to come into more full contact with the humidifying roller 12 during transport, thereby more evenly absorbing the wet wipe liquid in the liquid storage tank 10. The trapezoidal recess design allows the wet wipe liquid to form a certain flow and distribution within the recesses 16 when the humidifying roller 12 rotates, further promoting the even application of the wet wipe liquid onto the nonwoven fabric. This effectively improves the uniformity of the initial liquid addition to the nonwoven fabric, laying a good foundation for the uniform liquid addition of the subsequent spraying mechanism 11, and ultimately improving the uniformity of the distribution of the antibacterial agent and the quality of the wet wipe.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
