Description

Technical Field

[0001] This utility model relates to the field of wet wipe production technology, specifically to a wet wipe production line and its anti-lint humidification device. Background Technology

[0002] Wet wipes are a common cleaning product in people's daily lives, and their manufacturing technology has undergone many years of development and improvement. The current production of wet wipes typically includes multiple processes such as feeding and pulling, cutting and segmenting, folding and stacking, adding liquid for wetting, and packaging and sealing.

[0003] Wet wipes are generally made of non-woven fabric, which is formed by air-flowing or mechanically binding polymer chips, short fibers, or filaments into a web, and then reinforced by methods such as hydroentangling, needle punching, or thermal rolling. Different manufacturing processes result in lint shedding during transport due to friction. This not only affects the quality of the wet wipes, but the lint can also adhere to the conveyor equipment, potentially hindering its normal operation over time.

[0004] For example, Chinese patent document CN216423632U discloses an automated production line for wet wipes. In this production line, rolls of wet wipes are pre-cut to width and then fed through conveyor rollers and a guide device before entering a wet wipe folding device. After folding, the wipes enter a flattening device, which simultaneously flattens and pulls the wipes. The wipes are then humidified by a spray pipe through a humidifying device, and excess water is squeezed out by a squeezing device, falling into a water tank in the humidifying device. A cutting device then evenly cuts the long strips of wipes. The cut wipes enter a stacking device between the first and second belt drive groups. Regularly moving hammers press the wipes one by one onto a flipping plate. After a certain number of wipes are stacked, the flipping plate is tilted downwards, causing the stacked wipes to fall onto the top of a conveyor device, from where they are then transported to the next packaging process.

[0005] The aforementioned production line uses a spray humidification method to moisten the wet wipes during production, which to some extent prevents lint from forming in the raw materials. However, spray humidification can lead to uneven humidification of the raw materials. Adding too much water wastes water resources. Furthermore, to prevent water droplets from corroding the equipment during subsequent production, an additional squeezing device is needed to remove excess water from the wet wipes, which undoubtedly increases the equipment's cost and operating expenses. Adding too little water results in some raw materials not being properly moistened, making it impossible to completely prevent lint formation.

[0006] Therefore, in the production process of wet wipes, a device is needed that can uniformly humidify the raw materials of wet wipes, thereby reducing equipment operating costs and preventing lint accumulation from affecting the normal operation of production equipment. Utility Model Content

[0007] The purpose of this invention is to provide a wet wipe production line that can evenly humidify raw materials while avoiding excessive cost increases. It also provides an anti-lint humidification device for use in the aforementioned wet wipe production line.

[0008] To solve the above problems, the present invention provides a wet wipe production line with the following technical solution:

[0009] A wet wipe production line includes an unwinding device and a humidifying device located downstream of the unwinding device. The unwinding device is used to output raw materials for wet wipes along a set wet wipe conveying path. The humidifying device includes a frame, a humidifying container for holding water, a humidifying roller located between the humidifying container and the raw material conveying path, and a drive device for driving the humidifying roller to rotate. The humidifying container, the humidifying roller, and the drive device are all mounted on the frame. The top of the humidifying container has an opening.

[0010] The bottom of the outer periphery of the humidifying roller is located inside the humidifying container so as to be immersed below the liquid surface of the water in the humidifying container, and the top of the outer periphery of the humidifying roller is located above the opening of the humidifying container so as to contact the raw materials conveyed from upstream of the wet wipe production line.

[0011] This utility model's wet wipe production line incorporates a humidification device at the output end of the material roll. This allows the raw materials output from the roll to be moistened through rotational contact with the humidification roller, which carries water from a humidification container. After moistening the raw materials, excess water flows back into the humidification container, allowing for water reuse and eliminating water waste. Therefore, compared to spray humidification, the rotational contact method with the raw materials ensures even wetting, prevents lint shedding during movement, and avoids excessive water dripping that could corrode the equipment. Furthermore, it eliminates the need for a squeezing process, reducing equipment usage and maintenance costs.

[0012] Furthermore, the humidification device also includes a pressing component for adjusting the pressure between the wet wipe raw material and the humidification roller, the pressing component being mounted on the frame and located above the humidification roller.

[0013] Furthermore, the pressing assembly includes a pressing roller driver and a pressing roller. The end of the pressing roller is rotatably mounted on the output end of the pressing roller driver. The raw material is wound between the pressing roller and the humidifying roller to move up and down under the drive of the pressing roller driver.

[0014] Furthermore, the pressure roller includes an input roller assembly located on the left side of the humidifying roller and an output roller located on the right side of the humidifying roller. The input roller assembly includes a connecting arm, a first input roller, and a second input roller. The first input roller is rotatably mounted on the output end of the pressure roller driver. One end of the connecting arm is adjustablely mounted on the first input roller, and the second input roller is rotatably mounted on the other end of the connecting arm, so as to adjust the contact pressure between the raw material and the humidifying roller by adjusting the tilt angle of the connecting arm.

[0015] Furthermore, the humidification device also includes a liquid supply device, which includes a water storage container, a water inlet pipe, a water pump, and a drain pipe. The water pump is installed on the water inlet pipe, which is used to connect to the water storage container and supply water to the humidification container. The drain pipe is used to discharge the water in the humidification container.

[0016] Furthermore, the unwinding device includes a support frame for placing the raw material roll, a guide structure for guiding the conveying path of the wet wipe raw material, and a drive component for driving the conveying of the raw material. The guide structure and the drive component are both mounted on the support frame.

[0017] The beneficial effects of the above-mentioned technical solution provided by this utility model are summarized as follows:

[0018] 1. This utility model's wet wipe production line incorporates a humidifying device at the output end of the material roll. This allows the raw materials output from the roll to be moistened through rotational contact with the humidifying roller. The humidifying roller carries water from a humidifying container.

Therefore, compared to spray humidification, the rotating contact of the humidifying roller with the raw materials ensures even wetting, prevents lint shedding during movement, and avoids excessive water dripping that could corrode the equipment. Furthermore, it eliminates the need for a squeezing process, reducing equipment usage and maintenance costs.

[0019] 2. The setting of the pressing component allows the device to adjust the moisture level of the raw material by adjusting the contact area between the raw material and the humidifying roller, thus improving the applicability of the device.

[0020] To solve the above problems, this utility model also provides a lint-proof and humidifying device for wet wipes, which adopts the following technical solution:

[0021] A humidifying device for preventing lint from falling off wet wipes includes a frame, a humidifying container for holding water, a humidifying roller located between the humidifying container and the raw material conveying path, and a drive device for driving the humidifying roller to rotate. The humidifying container, the humidifying roller and the drive device are all mounted on the frame, and the top of the humidifying container has an opening.

[0022] The bottom of the outer circumference of the humidifying roller is located inside the humidifying container so as to be immersed below the liquid surface of the water in the humidifying container, and the top of the outer circumference of the humidifying roller is located above the opening of the humidifying container so as to contact the raw materials conveyed from upstream of the wet wipe production line.

[0023] Its beneficial effects are as follows: By installing a humidifying device at the output end of the material roll, the raw materials output from the roll can be moistened through rotational contact with the humidifying roller. The humidifying roller carries water from the humidifying container. After wetting the raw materials, excess water flows back into the humidifying container, allowing for water reuse and eliminating water waste. Therefore, compared to spray humidification, the rotational contact of the humidifying roller with the raw materials ensures uniform wetting, prevents lint from falling off during movement, and avoids excessive water dripping that could corrode the equipment. Furthermore, it eliminates the need for a squeezing process on the wet wipes, reducing the cost of equipment use and maintenance.

[0024] Furthermore, the humidification device also includes a pressing component for adjusting the pressure between the wet wipe raw material and the humidification roller. The pressing component is mounted on the frame and located above the humidification roller.

The raw material is wound between the pressing roller and the humidifying roller to move up and down under the drive of the pressing roller driver.

[0026] Furthermore, the pressure roller includes an input roller assembly and an output roller. The input roller assembly includes a connecting arm, a first input roller, and a second input roller. The first input roller is rotatably mounted on the output end of the pressure roller driver. One end of the connecting arm is adjustablely mounted on the first input roller, and the second input roller is rotatably mounted on the other end of the connecting arm, so as to adjust the contact pressure between the raw material and the humidifying roller by adjusting the tilt angle of the connecting arm.

[0027] Furthermore, the humidification device also includes a liquid supply device, which includes a water storage container, a water inlet pipe, a water pump, and a drain pipe. The water pump is installed on the water inlet pipe, which is used to connect to the water storage container and supply water to the humidification container.

[0040] An embodiment of the wet wipe production line of this utility model includes, in sequence from the starting point to the end point, an unwinding device 1, a humidifying device 2, a cutting device, a folding device, a flipping device, a diversion conveying device, and a liquid filling and packaging device. It should be noted that since most of the structure of the wet wipe production line is prior art, this embodiment only mainly describes the humidifying device 2 involved in the improvement and innovation of the wet wipes. Therefore, it is only described in the accompanying drawings (see attached diagram). Figure 1 The diagram shows the humidifying device 2 and its upstream unwinding device 1, while omitting other downstream equipment. The unwinding device 1 is used to output the raw material for the wet wipes along a predetermined wet wipe conveying route, defining the wet wipes as being conveyed from left to right. The humidifying device 2 is located to the right of the unwinding device 1 and is adjacent to it. The humidifying device 2 is used to humidify the raw material for the wet wipes to prevent the wet wipes from shedding lint.

[0041] First, let's introduce the unwinding device 1, such as... Figure 1 As shown, the unwinding device 1 includes a support frame 11, a guide structure 12, and a drive component. The support frame 11 is used to hold the raw material roll, and the guide structure 12 is located at the right end of the support frame 11 to guide the wet wipe raw material to the right. The guide structure 12 includes two parallel guide rollers 121, both of which extend in the front-to-back direction. The raw material is wound around the two guide rollers 121 and moves to the right. The drive component is a motor, which drives the raw material to be conveyed to the right. In other embodiments, the number of guide rollers 121 may also be three or four.

[0042] Then, the humidifier 2 will be introduced, such as... Figures 1 to 5 As shown, the humidification device 2 includes a frame 22, a humidification container 24, a humidification roller 26, a liquid feeder 25, a pressing assembly 23, and a drive device 27. The humidification container 24, the humidification roller 26, and the drive device 27 are all mounted on the frame 22.

[0043] The frame 22 includes two vertically extending mounting plates 221 located at the front and rear ends of the humidifying container 24, and the humidifying container 24 is fixed on the mounting plates 221.

[0044] The humidifying container 24 is a semi-circular water tank extending front to back, with an opening at its upper end, and is used to hold water. In other embodiments, the humidifying container 24 may also be a rectangular or elliptical water tank extending front to back.

[0045] like Figure 3 and Figure 4 As shown, the liquid supply device 25 includes a water storage container 251, an inlet pipe 252, a water pump 254, and an outlet pipe. The water storage container 251 is a vertically extending water tank located at the rear of the frame 22. The water pump 254 is mounted on the inlet pipe 252, one end of which is connected to the lower end of the water storage container 251, and the other end is connected to the opening of the humidification container 24 to drain water into the humidification container 24. One end of the outlet pipe 253 is connected to the upper end of the water storage container 251, and the other end is connected to the bottom of the humidification container 24 to drain water from the humidification container 24.

[0046] like Figure 2 , Figure 4 and Figure 5 As shown, the humidifying roller 26 extends in the front-to-back direction, with both its front and rear ends mounted on corresponding mounting plates 221. The humidifying roller 26 is located between the humidifying container 24 and the raw material conveying path. The bottom of the outer circumference of the humidifying roller 26 is located inside the humidifying container 24, and the bottom of the humidifying roller 26 is immersed below the water surface in the humidifying container 24 to moisten the roller 26. The top of the outer circumference of the humidifying roller 26 is located above the opening of the humidifying container 24 to contact the raw materials conveyed from upstream of the wet wipe production line, and transfers water to the raw materials as the humidifying roller 26 rotates. The driving device 27 is a motor located at the front end of the humidifying roller 26, and is used to drive the humidifying roller 26 to rotate.

[0047] In addition, such as Figure 2 , Figure 4 and Figure 5 As shown, the pressing assembly 23 is used to press down the wet wipe raw material and press it firmly onto the humidifying roller 26, and can adjust the degree of pressing between the wet wipe raw material and the humidifying roller 26. The pressing assembly 23 includes a pressing roller 232 located above the humidifying roller 26 and a pressing roller driver 231 for driving the pressing roller 232 to move up and down. The axis of the pressing roller 232 extends forward and backward. The pressing roller driver 231 consists of two pressing cylinders located above the humidifying roller 26. The two pressing cylinders are located at the front and rear ends of the humidifying roller 26, respectively, and both pressing cylinders are fixedly mounted on corresponding mounting plates 221. The lower end of the pressing cylinder is the output end, and the rotating seats at the front and rear ends of the pressing roller 232 are fixedly connected to the output ends of the two pressing cylinders, respectively. By outputting the up and down linear motion of the pressing roller driver 231, the degree of pressing between the raw material and the humidifying roller 26 can be adjusted to adjust the humidification degree of the raw material.

[0048] There are three pressure rollers 232 arranged in parallel, including an input roller assembly 233 located to the left of the humidifying roller 26 and an output roller 237 located to the right of the humidifying roller 26. The input roller assembly 233 includes a connecting arm 236, a first input roller 234, and a second input roller 235. The first input roller 234 is rotatably mounted on the output end of the pressure roller driver 231. The connecting arm 236 extends upward at an angle from left to right, and its upper right end is fixedly mounted on the first input roller 234 by fasteners. The second input roller 235 is rotatably mounted on the lower left end of the connecting arm 236. Specifically, by adjusting the tilt angle of the connecting arm 236 with fasteners, the contact pressure between the raw material and the humidifying roller 26 can be further controlled, improving the uniformity of raw material humidification. In other embodiments, the pressure roller driver 231 can also be a servo electric cylinder.

[0049] The raw material for the wet wipes passes from top to bottom between the first input roller 234 and the second input roller 235, then passes under the output roller 237 and moves to the right under the drive of the drive unit.

[0050] The working principle of an embodiment of a wet wipes production line is as follows:

[0051] During production line operation, the raw materials for wet wipes are conveyed from left to right. Activating the drive unit 27 causes the humidifying roller 26 to rotate. At this time, the bottom of the humidifying roller 26 is immersed in the water within the humidifying container 24. When the raw material of the wet wipes comes into contact with the upper surface of the humidifying roller 26, the moisture adhering to the humidifying roller 26 is transferred to the raw material as it rotates, ensuring the raw material is evenly moistened. The humidification effect can be adjusted by changing the downward movement of the pressing cylinder and the operating speed of the drive unit 27, depending on the thickness of the raw material. Furthermore, the tilt angle of the connecting arm 236 can be adjusted via the locking mechanism, thereby adjusting the tension of the raw material on the humidifying roller 26 to further regulate the humidification effect.

[0052] An embodiment of a lint-proof and humidifying device for wet wipes provided by this utility model:

[0053] The lint-proof humidifying device in this embodiment is exactly the same as the humidifying device in the wet wipe production line described above, and will not be described again here.

[0054] In other embodiments, the pressing component can be omitted, and the output raw material and the upper surface of the humidifying roller can be kept in close contact by adjusting the guide structure.

[0055] In other embodiments, the liquid supply device can be omitted, and the normal operation of the humidification device can be ensured by increasing the volume of the humidification container and the operator's regular water injection.

[0056] Based on the above description in this specification, those skilled in the art will also understand that the following terms, such as "upper," "lower," "front," "rear," "left," "right," "width," "horizontal," "top," "bottom," "inner," and "outer," which indicate orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings of this specification.
