Description

Technical Field

[0001] This utility model relates to the technical field of wet wipe production equipment, specifically a device for preventing paper folding at the edge of a wet wipe production line. Background Technology

[0002] Before the wet wipes are slit during the production process, they need to be transferred from the stacking equipment to the slit equipment. Therefore, a handling and conveying structure is required for this transfer. However, since most handling devices are like... Figure 6 The toothed structure shown is designed to work with multiple conveyor belts to transfer wet wipes between different structures. Because the toothed structure of the handling device is staggered with the multiple conveyor belts, cavities exist at the edges of the wet wipes during transfer or transport, causing the bottom layer of wipes to sag under gravity. During subsequent transport, the strip-shaped wipes need to be conveyed along their strip direction. Therefore, when transferred to the slitting equipment, the sagging wipes at the bottom will fold, becoming trapped between the inner seals of the packaging during the subsequent sealing process, thus hindering the sealing. In view of this, we propose an edge-folding anti-folding device for a wet wipe production line. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example 1 A device to prevent paper from folding at the edge of a wet wipe production line, such as Figures 1-6 As shown, it includes a workbench 1; the workbench 1 is equipped with a conveying mechanism 2, which can convey the wet wipes pile and move the entire wet wipe to the subsequent processing equipment.

[0016] Specifically, the conveying mechanism 2 includes two drive rollers 21, which are symmetrically arranged on the worktable 1. A conveyor belt 22 is fitted on the drive rollers 21. The structure of the drive rollers 21 can drive the conveyor belt 22. At the same time, there are multiple sets of conveyor belts 22, and the multiple sets of conveyor belts 22 are equidistant. The drive rollers 21 can drive multiple different sets of conveyor belts 22 synchronously at the same time.

[0017] In addition, a conveying device 24 is provided at both ends of the workbench 1, and a conveyor belt device 25 is provided at the end of the conveyor belt 22. The conveyor belt device 25 is perpendicular to the direction of the conveyor belt 22. The conveying device 24 can transport the wet wipes pile, transporting the wet wipes pile to the conveyor belt or removing it from the conveyor belt 22. The conveying device 24 has an L-shaped toothed structure, which is convenient to cooperate with multiple sets of conveyor belts 22. Multiple sets of conveyor belts 22 are respectively arranged through the gaps between the teeth of the conveying device 24. The conveyor belt device 25 can transport the wet wipes pile, which is convenient for subsequent cutting of the wet wipes pile.

[0018] Example 2 like Figures 1-5 As shown, based on Embodiment 1, the workbench 1 is equipped with a smoothing mechanism 3. The smoothing mechanism 3 can smooth out the wet wipes that are drooping at the edges during the conveying of the wet wipes pile, so as to prevent the drooping wet wipes from folding to the bottom of the wet wipe pile when they are transported to the conveyor belt and affecting subsequent processing operations.

[0019] In this embodiment, the smoothing mechanism 3 includes a movable frame 31, which is slidably connected to the workbench 1. A support roller 32 is rotatably connected to the movable frame 31, and a correction belt 33 is connected to the support roller 32. The movable frame 31 can be raised and lowered, so that the drooping wet wipes can be gradually restored during the smoothing operation. The correction belt 33 is in the same direction as the conveyor belt 22. At the same time, when the correction belt 33 is below the conveyor belt 22, its movement speed is faster than that of the conveyor belt 22, so that the drooping wet wipes can be smoothed into the wet wipe pile during the smoothing operation.

[0020] It is worth noting that there are four support rollers 32, which are rotatably connected to the edge of the moving frame 31. A transmission rod 34 is fixedly connected to the inner circumferential wall of the correction belt 33. The length of the transmission rod 34 is greater than the width of the correction belt 33. An electric push rod 35 is fixedly connected inside the worktable 1. The end of the electric push rod 35 is fixedly connected to the moving frame 31. A motor 36 is fixedly connected to the moving frame 31. A transmission disc 37 is fixedly connected to the end of the output shaft of the motor 36. A locking block 23 is rotatably connected to the bottom of the conveyor belt 22 and the side of the transmission disc 37. The locking blocks 23 are equidistant from each other, and the distance between the locking blocks 23 is greater than the diameter of the transmission rod 34. The clamp 23 structure can cooperate with the conveyor rod, so that the correction belt 33 can be driven by the transmission disc 37 or the conveyor belt 22. The clamp 23 has a plate-like structure and the rotation angle of the clamp 23 is less than 90 degrees. A buffer spring is fixedly connected to the inside of the clamp 23 to keep the clamp 23 in the unfolded state. At the same time, the driving speed between the transmission disc 37 and the conveyor belt 22 is different. Therefore, when the moving speed of the transmission rod 34 is faster than that of the conveyor belt 22, the clamp 23 can be rotated back to its original position. When the moving speed of the transmission rod 34 is slower than that of the conveyor belt 22, the automatically unfolded clamp 23 on the conveyor belt 22 can drive the transmission rod 34.

[0021] In addition, a distance sensor 38 is fixedly connected to one end of the mobile frame 31. The distance sensor 38 can detect the position of the wet wipes pile, so that the mobile frame 31 can be raised and lowered according to the position of the wet wipes.

[0022] In use, the edge-protecting anti-folding device for a wet wipe production line of this utility model involves a conveyor device 24 transporting a stack of wet wipes from a cutting and stacking device onto a conveyor belt 22. The conveyor belt 22 moves continuously under the drive of a drive rod, conveying the wet wipe stack from one end to the other. When the wet wipe stack reaches the distance sensor 38, the sensor detects the stack. When the length of the wet wipe stack extends beyond the conveyor belt 22, the moving seat moves upward continuously driven by an electric push rod 35. Simultaneously, a motor 36 drives a support rod to rotate continuously, causing a correction belt 33 to rotate continuously. The correction belt 33 rotates faster than the transmission belt, thus moving relative to the wet wipes towards the end, smoothing out any sagging wet wipes. When the correction belt 33 approaches the conveyor belt 22, the motor 36 stops, and the locking block 23 at the bottom of the conveyor belt 22 continues to move the correction belt 33. Meanwhile, the end of the correction belt 33 corresponds to the position of the conveying device 24. Therefore, when the wet wipes move to the end of the conveyor belt 22, the conveying device 24 can transport the wet wipes to the conveyor belt device 25 for convenient subsequent operations.
