Description

Technical Field

[0001] The invention relates to the technical field of wet wipes liquid addition, in particular to an online follow-up type side liquid addition system. Background Art

[0002] In the field of wet wipes production, humidification is an important link in the wet wipes manufacturing process, which is directly related to the moisturizing performance and comfort of wet wipes. Traditional wet wipes liquid addition methods mostly use top spraying, that is, spraying liquid from the top of the wet wipes to the surface of the wet wipes. However, this liquid addition method has many shortcomings.

[0003] First, the top spraying method easily leads to uneven distribution of liquid on the surface of the wet wipes, affecting the overall moisturizing effect of the wet wipes. Since factors such as the pressure, angle and flow of the spraying liquid are difficult to accurately control, it often leads to too much liquid in some parts of the wet wipes and insufficient liquid in other parts, thus affecting the user experience of the wet wipes.

[0004] Secondly, the top spraying method needs to be shut down during the humidification process in order to transport the wet wipes to the bottom of the spraying device for humidification. This shutdown operation not only reduces production efficiency, but also increases production costs and labor intensity.

[0005] In addition, as consumers' requirements for wet wipes quality continue to increase, the traditional top spraying method can no longer meet the market's demand for high-quality wet wipes. Therefore, it is particularly important to develop a new wet wipes liquid addition system that can continuously and evenly humidify wet wipes and improve production efficiency.

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] Embodiment 1:

[0037] like Figure 1-5As shown, an online follow-up side liquid adding system comprises a frame 1, on which a wet wipes conveying mechanism 2 for continuously conveying wet wipes is installed; a side liquid adding mechanism 3 is installed on the frame corresponding to a position directly above the conveying surface of the wet wipes conveying mechanism, and the side liquid adding mechanism 3 is used to add liquid from the side of the wet wipes; the side liquid adding mechanism 3 comprises a first side spray liquid adding plate 301 and a second side spray liquid adding plate 302, the first side spray liquid adding plate and the second side spray liquid adding plate are relatively installed on both sides of the conveying surface of the wet wipes conveying mechanism, wherein liquid outlet holes 303 are installed on the first side spray liquid adding plate and the second side spray liquid adding plate at positions directly facing the sides of the wet wipes, and the liquid outlet holes are connected to a liquid supply module; the frame 1 is also equipped with a follow-up reciprocating drive mechanism 8 for driving the side liquid adding mechanism to follow the movement of the wet wipes.

[0038] As a preferred design scheme, the spacing between the first side spray liquid adding plate 301 and the second side spray liquid adding plate 302 can be adjusted, and the side liquid adding mechanism also includes a cloth pressing plate 304 that can be raised and lowered, and the cloth pressing plate is installed between the first side spray liquid adding plate and the second side spray liquid adding plate, and the cloth pressing surface of the cloth pressing plate 304 is installed facing the top of the wet wipes on the wet wipes conveying mechanism, and the first side spray liquid adding plate, the second side spray liquid adding plate, and the cloth pressing plate cooperate to squeeze the finished wet wipes toward the middle for subsequent liquid spraying, and at the same time, the cloth pressing plate presses the product to prevent the product from arching.

[0039] The spacing between the first side spray liquid adding plate and the second side spray liquid adding plate is designed to be adjustable, and a cloth pressing plate that can be raised and lowered is introduced. This preferred solution further enhances the function and performance of the online follow-up side liquid adding system, and its beneficial effects are specifically reflected in the following aspects: (1) Enhanced humidification uniformity: By adjusting the spacing between the first side spray liquid adding plate and the second side spray liquid adding plate, it can adapt to wet wipes products of different thicknesses or widths, ensuring that the side liquid adding mechanism can more accurately control the humidification area and humidification amount. With the use of the cloth pressing plate, the wet wipes are stably flattened during transportation, avoiding the problem of uneven humidification caused by wrinkles or arches of the wet wipes, thereby further improving the uniformity and effect of humidification. (2) Improved humidification efficiency: The design of the cloth pressing plate not only helps to stabilize the wet wipes, but also squeezes the wet wipes toward the middle during the humidification process, making the wet wipes more closely in contact with the side liquid adding plate, which is conducive to the penetration and absorption of the liquid. This design reduces the amount of liquid and time required for humidification, improves humidification efficiency, and also helps to reduce liquid waste. (3) Enhance product adaptability: The first side spray liquid adding plate and the second side spray liquid adding plate with adjustable spacing, as well as the liftable cloth pressing plate, enable the system to flexibly adapt to wet wipes products of different specifications and types. This high degree of flexibility and adaptability gives the system a wider application prospect in the field of wet wipes production and can meet more diverse production needs. (4) Improve product quality: By precisely controlling the humidification area and humidification amount, and using the cloth pressing plate to stabilize the wet wipes and prevent them from arching, the system can produce smoother and more evenly humidified wet wipes products. Such high-quality products can better meet the needs of consumers and enhance the market competitiveness of products. (5) Optimize the operation process: The spacing adjustment and cloth pressing plate lifting functions enable operators to easily adjust system parameters as needed to adapt to the production needs of different products. This design simplifies the operation process, reduces the difficulty of operation, and improves production efficiency and convenience of operation.

[0040] The specific driving form is designed. A linear reciprocating drive mechanism 1 305 and a linear reciprocating drive mechanism 2 306 are respectively installed on the back of the first side liquid spraying plate 301 and the second side liquid spraying plate 302 on the frame 1, wherein the movement directions of the linear reciprocating drive mechanism 1 and the linear reciprocating drive mechanism 2 are perpendicular to the conveying direction of the wet wipes conveying mechanism. A linear reciprocating drive mechanism 3 307 for driving the cloth pressing plate to rise and fall is installed on the frame. The linear reciprocating drive mechanism 1 305, the linear reciprocating drive mechanism 2 306 and the linear reciprocating drive mechanism 3 307 all adopt cylinders, namely, cylinder 1, cylinder 2 and cylinder 3 respectively, to independently drive the first side liquid spraying plate, the second side liquid spraying plate and the cloth pressing plate. In order to ensure the stability of the movement of the first side liquid spraying plate, the second side liquid spraying plate and the cloth pressing plate, each is configured with a guide rod and guide sleeve structure 308. The above structural design has the following designs: (1) Precise control: Cylinder 1 and Cylinder 2 respectively drive the first side spray liquid adding plate and the second side spray liquid adding plate to perform linear reciprocating motion, and the motion direction is perpendicular to the conveying direction of the wet wipe conveying mechanism. This design can accurately control the moving position and speed of the side liquid adding plate, thereby realizing precise control of the side humidification of the wet wipe. At the same time, Cylinder 3 drives the cloth pressing plate to rise and fall, further enhancing the control accuracy and flexibility of the system. (2) Stable and reliable: The introduction of the guide rod and guide sleeve structure provides stable support and guidance for the movement of the first side spray liquid adding plate, the second side spray liquid adding plate and the cloth pressing plate, effectively preventing problems such as uneven humidification or equipment damage caused by unstable movement. This design not only improves the stability and reliability of the system, but also extends the service life of the equipment. (3) High efficiency and energy saving: As a driving source, the cylinder has the advantages of simple structure, rapid action, and easy maintenance. At the same time, the driving method of the cylinder can achieve rapid response and precise control, thereby improving the humidification efficiency and energy saving performance of the system. In addition, the driving cost of the cylinder is relatively low, which helps to reduce production costs. (4) Strong adaptability: By adjusting the stroke and speed of the cylinder, it can flexibly adapt to different specifications and types of wet wipes products to meet diverse production needs. This high degree of flexibility and adaptability makes the system have a wider application prospect in the field of wet wipes production. (5) Easy maintenance: The design of the cylinder and guide rod and guide sleeve structure makes the maintenance and maintenance of the system simple and convenient. Operators can easily inspect and replace the cylinder, reducing the difficulty and cost of maintenance. In summary, the design of using the cylinder as the linear reciprocating drive mechanism and configuring the guide rod and guide sleeve structure has shown significant beneficial effects in terms of precise control, stability and reliability, high efficiency and energy saving, strong adaptability and easy maintenance, further improving the performance and function of the online follow-up side liquid addition system.

[0041] The first side spray liquid adding plate 301 and the second side spray liquid adding plate are internally installed with a liquid adding cavity, the first side spray liquid adding plate and the second side spray liquid adding plate are hollow structures, the first side spray liquid adding plate and the second side spray liquid adding plate are internally installed with a liquid adding cavity, the liquid outlet holes are evenly distributed on the inner side surfaces of the first side spray liquid adding plate and the second side spray liquid adding plate, the liquid outlet holes are connected with the liquid adding cavity, and the liquid adding cavity is connected with the liquid supply module. For the preferred design of the first side spray liquid adding plate and the second side spray liquid adding plate with internally designed liquid adding cavity, its beneficial effects are mainly reflected in the following aspects: (1) Uniform humidification: Since the first side spray liquid adding plate and the second side spray liquid adding plate are internally provided with a liquid adding cavity, and the liquid outlet holes are evenly distributed on their inner side surfaces, this enables the liquid to be evenly sprayed from the side of the wet wipes, ensuring that the wet wipes are evenly humidified during transportation. This design avoids the problem of uneven humidification that may occur in traditional liquid adding methods, and improves the humidification effect and quality of the product. (2) Efficient use of liquid: The design of the liquid adding chamber allows the liquid to be stored inside and evenly distributed to each liquid outlet, thereby improving the utilization efficiency of the liquid. Compared with the traditional top spraying method, the side liquid adding design can more accurately control the humidification amount, reduce liquid waste, and reduce production costs. (3) Compact structure: The first side spray liquid adding plate and the second side spray liquid adding plate adopt a hollow structure with a liquid adding chamber installed inside. This design makes the entire side liquid adding mechanism more compact and reduces the footprint of the equipment. At the same time, the hollow structure also helps to reduce the weight of the equipment and improve the flexibility and mobility of the equipment. (4) Easy maintenance and cleaning: The design of the liquid adding chamber and the liquid outlet makes the side liquid adding mechanism more convenient for maintenance and cleaning. The operator can easily clean and inspect the liquid adding chamber to ensure the normal operation and humidification effect of the equipment. At the same time, since the liquid outlets are evenly distributed on the inner side, the problem of uneven humidification caused by blockage is also reduced. (5) Improved production efficiency: Since the side liquid adding mechanism can achieve continuous and uniform humidification of wet wipes, it can greatly improve production efficiency. This design avoids the disadvantage of the traditional liquid adding method that requires shutdown operation, making wet wipes production more efficient, continuous and stable.

[0042] The following reciprocating drive mechanism 8 includes a transverse slide rail 801 arranged along the conveying direction of the wet wipes conveying mechanism, a sliding seat 802 is installed on the transverse slide rail, the side liquid adding mechanism 3 is installed on the sliding seat, and a reciprocating drive mechanism 803 for driving the sliding seat to slide along the transverse slide rail is installed on the frame. The sliding speed of the sliding seat 802 is consistent with the conveying speed of the wet wipes conveyor 2, which can achieve: (1) Synchronous humidification: By installing a transverse slide rail arranged along the conveying direction of the wet wipes conveying mechanism, installing a sliding seat on it, and then installing the side liquid adding mechanism on the sliding seat, the synchronous movement of the side liquid adding mechanism and the wet wipes conveying mechanism is achieved. This design ensures that the side liquid adding mechanism can move with the conveying of the wet wipes, thereby achieving continuous and uniform humidification of the wet wipes. The sliding speed of the sliding seat is consistent with the conveying speed of the wet wipes conveyor, further ensuring the consistency and stability of the humidification effect. (2) Improved humidification efficiency: Since the side liquid adding mechanism can move with the conveying of the wet wipes, there is no need to stop the machine for humidification operation, which greatly improves production efficiency. At the same time, since the humidification process is continuous and uniform, rework and waste caused by uneven humidification are reduced, further improving production efficiency and economic benefits.

[0043] The wet wipes conveying mechanism includes a humidification section conveyor belt 201 and a switching section conveyor belt 202, and the power sources of the humidification section conveyor belt 201 and the switching section conveyor belt 202 are independent of each other; a switching mechanism 4 for squeezing and raising the wet wipes after adding liquid is installed on the frame corresponding to the position of the switching section conveyor belt. The above design: (1) By installing the switching mechanism on the frame, the squeezing and raising of the wet wipes after adding liquid are realized. The switching mechanism includes a pressing conveyor belt movably installed on the frame, and an extrusion conveying channel is formed between the pressing conveyor belt and the switching section conveyor belt. As the wet wipes are conveyed in the channel, the spacing between the pressing conveyor belt and the switching section conveyor belt decreases linearly along the conveying direction, thereby squeezing the wet wipes to make them more compact and flat. This design not only improves the quality of the wet wipes, but also helps to reduce the deformation and damage of the wet wipes during subsequent processing. The bag-switching mechanism 4 includes a bag-pressing conveyor belt 401 movably mounted on the frame, and an extrusion conveying channel is formed between the bag-pressing conveyor 401 and the bag-switching section conveyor belt 202, and the spacing between the bag-pressing conveyor and the bag-switching section conveyor belt decreases linearly along the conveying direction; the specific driving form is as follows: a lifting rail 402 is installed on the frame 1 along the lifting direction of the bag-pressing conveyor belt, and a lifting seat 403 is movably installed on the lifting rail. The bag-pressing conveyor belt is installed on the lifting seat, and a height adjustment mechanism 404 for adjusting the height of the lifting seat on the lifting rail is installed on the frame. In this embodiment, the height adjustment mechanism adopts a threaded screw structure, and the design of the lifting rail and the height adjustment mechanism makes the maintenance and maintenance of the bag-switching mechanism simpler and more convenient. The operator can easily clean, lubricate and inspect the rail, lifting seat and adjustment mechanism to ensure the normal operation and extrusion effect of the equipment. At the same time, due to the compact structure and easy disassembly, it is also convenient for the maintenance and replacement of the equipment.

[0044] A recovery hopper 9 is installed on the frame 1 at a position corresponding to the humidification section conveyor belt 201 and the switching section conveyor belt 202, and the liquid supply module includes a liquid supply box 5. The recovery hopper is connected to the liquid supply box. The liquid supply box is connected to the liquid outlet holes on the first side spraying plate and the second side spraying plate through a liquid supply pipeline 6. A control valve 7 for controlling the on-off of the pipeline is installed on the liquid supply pipeline. In this embodiment, the control valve adopts a pneumatic valve. The above structural design has the following advantages: (1) Efficient resource utilization and environmental protection: By installing a recovery hopper corresponding to the humidification section conveyor belt and the switching section conveyor belt on the frame, the excess liquid dripping during the humidification and switching process can be effectively collected. These liquids flow into the liquid supply box through the recovery hopper, realizing the reuse of resources and reducing waste. At the same time, this also avoids the direct discharge of liquid into the environment, which is beneficial to environmental protection. (2) Flexible liquid supply control: The liquid supply module includes a liquid supply box, which is connected to the liquid outlet holes on the first side spraying plate and the second side spraying plate through a liquid supply pipeline. This design makes the liquid supply process more flexible and controllable. As a control valve, pneumatic valves have the characteristics of fast response speed and precise control. They can quickly adjust the liquid supply according to production needs to ensure the consistency and stability of the humidification effect. (3) Reduce costs: By recycling excess liquid and reusing it, and adopting efficient and reliable liquid supply control methods, it helps to reduce production costs. At the same time, pneumatic valves usually have lower energy consumption and maintenance costs than other types of valves, such as electric valves, further reducing the company's operating costs.

[0045] The working principle of this device is as follows:

[0046] When the electric eye detects that the wet wipes product is transported from the front conveyor platform, the humidification section conveyor belt in this section of the conveyor platform starts to accelerate the wet wipes product and increase the distance between the wet wipes products. When the wet wipes product is transported to the liquid adding position, cylinder one drives the first side spray liquid adding plate, cylinder two drives the second side spray liquid adding plate, and cylinder three drives the cloth pressing plate to move at the same time. The first side spray liquid adding plate and the second side spray liquid adding plate clamp the product, and the cloth pressing plate presses the product to prevent the product from arching. At the same time, the pneumatic valve opens to start adding liquid to the product. The entire side spray device moves forward with the product driven by the transmission belt. During operation, the first side spray liquid adding plate and the second side spray liquid adding plate add liquid to the product at the same time. When the entire side spray device runs a certain distance with the product and reaches the required liquid adding amount, the pneumatic valve is closed. At this time, cylinder 1 drives the first side spray liquid adding plate, cylinder 2 drives the second side spray liquid adding plate, and cylinder 3 drives the cloth pressing plate to release the product at the same time. Liquid adding is completed. Subsequently, the product that has been added with liquid continues to move forward driven by the transmission belt, while the entire liquid adding device quickly retreats to the starting position, waiting for the arrival of the next package of products, and continues to humidify the next package of products. The switching device of the switching section conveyor belt can control the wet wipes product more accurately. When the wet wipes product passes, the device can adjust the height of the product by squeezing the wet wipes product to keep it consistent.
