Description

Technical Field

[0001] This utility model relates to the field of wet wipe production equipment design technology, specifically to a wet wipe pressing and folding device and a wet wipe folding machine. Background Technology

[0002] The 30-120 sheet wet wipe folding machine includes a wet wipe stacking device, which is used to stack wet wipes that have been cut to a specified length into a set number of layers. Existing wet wipe stacking devices use a crank-slider structure, moving vertically up and down during the stacking process. This means that after stacking a wet wipe, the device needs to rise to the top stop and then descend again for the next stacking cycle, resulting in a slow pace and low production efficiency. Utility Model Content

[0003] The wet wipe folding device and wet wipe folding machine designed in this utility model can at least partially solve the above problems.

[0004] The purpose of this utility model is to provide a wet wipe folding device, including an assembly plate and a driving component. A folding component is assembled on the first side of the assembly plate. The folding component includes a driving shaft and a folding assembly. One end of the driving shaft is driven and connected to the driving component, and the other end of the driving shaft is connected to an eccentric flywheel. The folding assembly is assembled on the eccentric flywheel via a planetary shaft. The rotation axis of the planetary shaft and the driving shaft do not coincide, and the folding assembly remains in a vertical state during the process of the driving shaft being driven and rotated by the driving component.

[0005] In some embodiments, the stacking assembly includes a stacking plate and a support, the top side of the support being fixedly connected to one end of the planetary shaft, and the bottom side of the support being detachably connected to the stacking plate.

[0006] In some embodiments, the support is Y-shaped, with two branches of the Y-shape connected to the stacking plate, the main trunk of the Y-shape connected to the planetary shaft, and the two branches spaced apart along the length of the stacking plate.

[0007] In some embodiments, a waist-shaped hole is formed on the branch of the Y-shape, and the length extension direction of the waist-shaped hole is parallel to the vertical direction.

[0008] In some embodiments, the bottom surface of the stacked plate is formed with multiple grooves extending through its two end faces.

[0009] In some embodiments, a counterweight is assembled on the eccentric flywheel, and the counterweight and the planetary shaft are respectively located on opposite sides of the drive shaft.

[0010] In some embodiments, the planetary shaft is connected to the drive shaft via a first synchronous belt drive, so that the planetary shaft and the drive shaft rotate synchronously in opposite directions.

[0011] In some embodiments, the drive component is assembled on a second side of the assembly plate, the second side being disposed opposite to the first side. The drive component includes a servo motor and a reducer, and the output shaft of the reducer is connected to the end of the drive shaft via a second synchronous belt drive.

[0012] In some embodiments, a first bearing housing is assembled on the assembly plate, and the drive shaft is rotatably connected to the first bearing housing; and / or, a second bearing housing is assembled on the eccentric flywheel, and the planetary shaft is rotatably connected to the second bearing housing.

[0013] This utility model also provides a wet wipe folding machine, including the above-mentioned wet wipe pressing and folding device.

[0014] This utility model relates to a wet wipe folding device and a wet wipe folding machine:

[0015] The planetary shaft is eccentrically mounted on the eccentric flywheel and remains vertical during the rotation of the drive shaft. When the drive shaft is driven to rotate, the stacking assembly can move horizontally and vertically at the same time, so that the distance between the wet wipes can be very small. There is no need to reserve too large a gap to compensate for the time difference caused by the lifting and lowering of the stacking assembly. This enables the simultaneous stacking of two wet wipes, improves production efficiency, and reduces the energy consumption of the drive components. Attached Figure Description

[0020] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. In the drawings, for clarity, the thickness of regions and layers is exaggerated. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed descriptions will be omitted.

[0021] The described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a full understanding of embodiments of the present invention. However, those skilled in the art will recognize that the technical solutions of the present invention can be practiced without one or more of the specific details described, or other methods, components, materials, etc., can be employed. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring various aspects of the present invention.

[0022] The following examples describe the wet wipe folding device and wet wipe folding machine of this utility model. These examples are only a portion of the embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. All other embodiments obtained by those skilled in the art without inventive effort should be covered within the scope of protection of this utility model.

[0023] Please refer to the reference. Figures 1 to 2 As shown in the figure, according to an embodiment of the present invention, a wet wipe folding device is provided, including an assembly plate 1 and a driving component (not indicated in the figure). A folding component (not indicated in the figure) is assembled on the first side of the assembly plate 1. The folding component includes a driving shaft 21 and a folding assembly (not indicated in the figure). One end of the driving shaft 21 is drivenly connected to the driving component, that is, the driving component can drive the driving shaft 21 to rotate when it is running. The other end of the driving shaft 21 is connected to an eccentric flywheel 211. The folding assembly is assembled on the eccentric flywheel 211 via a planetary shaft 221. The rotation axes of the planetary shaft 221 and the driving shaft 21 are not coincident, that is, an eccentric distance is formed between the planetary shaft 221 and the driving shaft 21. The folding assembly remains in a vertical state during the process of the driving shaft 21 being driven to rotate by the driving component.

[0024] In this technical solution, the planetary shaft 221 is eccentrically mounted on the eccentric flywheel 211 and remains vertical during the rotation of the drive shaft 21. When the drive shaft 21 is driven to rotate, the stacking assembly can form a lifting and lowering motion while also forming a left-right (or right-right) motion. Figure 1(The orientation shown is for reference) Lateral shifting allows for very small spacing between wet wipes, eliminating the need to leave excessive gaps to wait for the stacking components to return. This enables the simultaneous stacking of two wet wipes, improving production efficiency and reducing energy consumption of the drive components.

[0025] In some embodiments, the stacking assembly includes a stacking plate 223 and a support 224, the top side of the support 224 being fixedly connected to one end of the planetary shaft 221, and the bottom side of the support 224 being detachably connected to the stacking plate 223.

[0026] In this technical solution, the pressing plate 223 and the bracket 224 are detachably connected, and the pressing plate 223 of the size matching can be replaced according to the actual model of the wet wipe, thus making the wet wipe pressing device of this utility model more versatile.

[0027] In some embodiments, the length of the aforementioned stacking plate 223 should be at least greater than the length of a wet wipe to achieve reliable and complete stacking of the wet wipe.

[0028] In some embodiments, the support 224 is Y-shaped, and the two branches of the Y-shape are connected to the stacking plate 223, and the two branches are spaced apart along the length of the stacking plate 223, and the main body of the Y-shape is connected to the planetary shaft 221.

[0029] In this technical solution, the bracket 224 is designed in a Y shape, which can use two branches to form more uniform pressure on the long strip-shaped stacking plate 223, ensuring flat stacking.

[0030] In some embodiments, a waist-shaped hole 2241 is formed on the branch of the Y-shape, and the length extension direction of the waist-shaped hole 2241 is parallel to the vertical direction.

[0031] In this technical solution, by providing a waist-shaped hole 2241 on the branch, the relative height between the pressing plate 223 and the wet wipe below can be adjusted to ensure the pressing effect.

[0032] In some embodiments, the bottom surface of the pressing plate 223 is formed with a plurality of grooves 2231 that extend through its two end faces, so as to reduce the contact area between the pressing surface of the pressing plate 223 and the wet wipe, and prevent the wet wipe from adhering to the pressing plate 223 and affecting the normal operation of the pressing operation.

[0033] In some embodiments, a counterweight 212 is assembled on the eccentric flywheel 211. The counterweight 212 and the planetary shaft 221 are respectively located on opposite sides of the drive shaft 21. This makes the forces on both sides of the drive shaft 21 relatively balanced, which can ensure the smooth rotation of the drive shaft 21 and reduce the operating noise caused by mass imbalance.

[0034] In some embodiments, the planetary shaft 221 and the drive shaft 21 are connected by a first synchronous belt 23 so that the planetary shaft 221 and the drive shaft 21 rotate synchronously in opposite directions. This ensures that the stacking assembly is in a vertical state through active adjustment, thereby ensuring reliable stacking of the wet wipes. It is understood that the aforementioned planetary shaft 221, drive shaft 21, first synchronous belt 23 and eccentric flywheel 211 objectively form a planetary gear train structure, wherein the first synchronous belt 23 is equivalent to an internal gear and the eccentric flywheel 211 is equivalent to a planet carrier.

[0035] In some embodiments, the drive component is assembled on the second side of the assembly plate 1, the second side being disposed opposite to the first side. The drive component includes a servo motor 31 and a reducer 32. The output shaft of the reducer 32 is connected to the end of the drive shaft 21 via a second synchronous belt 33. Using the second synchronous belt 33 to transmit the rotation of the servo motor 31 to the drive shaft 21 simplifies the design of the transmission route.

[0036] In some embodiments, a first bearing housing 11 is assembled on the assembly plate 1, and the drive shaft 21 is rotatably connected to the first bearing housing 11; and / or, a second bearing housing 213 is assembled on the eccentric flywheel 211, and the planetary shaft 221 is rotatably connected to the second bearing housing 213. It is understood that corresponding bearings (e.g., ball bearings) are respectively provided in the aforementioned first bearing housing 11 and second bearing housing 213 to achieve reliable rotational support for the drive shaft 21 and the planetary shaft 221.

[0037] According to an embodiment of the present invention, a wet wipe folding machine is also provided, including the above-mentioned wet wipe pressing and folding device.

[0038] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
