Description

Technical Field

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

[0002] The paper receiving device of a 30-120 sheet wet wipe folding machine is a wet wipe stacking device used to neatly stack cut wet wipes according to a set number of sheets. Due to the need for neat stacking and counting, the paper receiving device needs to regularly catch the wet wipes pressed down by the pressing mechanism. To achieve neatness, it needs to maintain a fixed distance between the top layer of wet wipes and the pressing mechanism, and quickly move into the next stack within the time it takes for two wet wipes to be pressed in when the set number of stacked layers is reached. Previously, maintaining a fixed distance from the pressing mechanism required complex angle calculations, making the operation more complex, demanding a high level of operator skill, and resulting in high labor intensity.

[0004] The purpose of this utility model is to provide a paper receiving device, including a main support, on which two paper receiving assemblies are arranged in parallel. Each paper receiving assembly includes a drive shaft and a driven shaft arranged in parallel at intervals, and a plurality of paper receiving annular belts tensioned around the drive shaft and the driven shaft. Each paper receiving annular belt is arranged at intervals along the axial direction of the drive shaft and engages with the drive shaft. Each paper receiving annular belt is provided with a first paper receiving arm. The first paper receiving arms in the two paper receiving assemblies together form a first support platform for wet paper towels. The drive shafts of the two paper receiving assemblies can be driven to rotate synchronously and in opposite directions, so that the height of the first support platform rises or falls.

[0005] In some embodiments, the paper receiving assembly further includes a secondary support fixedly connected to the main support, and the drive shaft and driven shaft are rotatably assembled on the secondary support; and / or, each of the paper receiving annular belts is further provided with a second paper receiving arm, and each of the second paper receiving arms in the two paper receiving assemblies can also jointly form a second support platform for the wet paper towel.

[0006] In some embodiments, the two sub-supports form a receiving space for the wet tissue on opposite sides, and a tissue guide structure is provided at the top opening of the receiving space.

[0007] In some embodiments, the tissue guide structure includes a plurality of guide rods spaced axially along the drive shaft, each guide rod being fixed to the sub-support, and the top of each guide rod on the two sub-supports forming a flared structure that gradually widens from bottom to top.

[0008] In some embodiments, the axial distance between the drive shaft and the driven shaft can be adjusted.

[0009] In some embodiments, the two axial ends of the driven shaft are connected to the main support and the secondary support via a spacing adjustment member.

[0010] In some embodiments, the secondary support is a plate, and the main support includes a first plate that is parallel and spaced apart from each of the secondary supports and a second plate that is fixedly connected to a first side of the first plate.

Detailed Implementation

[0019] 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.

[0020] 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.

[0021] The following examples describe the paper receiving 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.

[0022] Please refer to Figure 1As shown, according to an embodiment of the present invention, a paper receiving device is provided, including a main support 1. Two paper receiving assemblies (not labeled in the figure) are arranged parallel to each other on the main support 1. Each paper receiving assembly includes a drive shaft 21 and a driven shaft 22 arranged parallel to each other vertically. It also includes a plurality of paper receiving annular belts 23 tensioned around the drive shaft 21 and the driven shaft 22. Each paper receiving annular belt 23 is spaced apart along the axial direction of the drive shaft 21 and meshes with the drive shaft 21. Thus, when the drive shaft 21 is driven to rotate, it will drive each meshing paper receiving annular belt 23 to rotate around it. It is understood that each drive shaft 21 has a plurality of drive teeth (not labeled in the figure) arranged around its axis. The inner wall of the paper-receiving annular belt 23 is provided with a plurality of driven teeth (not shown in the figure, not labeled) that mesh with each of the driving teeth. Each of the paper-receiving annular belts 23 is provided with a first paper-receiving arm 231. The first paper-receiving arms 231 in the two paper-receiving assemblies together form a first support platform (not labeled in the figure) for the wet paper towel 100. The drive shafts 21 of the two paper-receiving assemblies can be driven to rotate synchronously and in opposite directions, so that the height of the first support platform rises or falls. It is understood that the aforementioned synchronous means that the magnitude of the rotation speed of the two is equal, and in opposite directions means that the direction of the rotation speed of the two is opposite, that is, one is clockwise and the other is counterclockwise.

[0023] In this technical solution, each of the two paper receiving assemblies is provided with a paper receiving annular belt 23 that can mesh with the drive shaft 21, and each paper receiving annular belt 23 has a first paper receiving arm 231 that can form a first support platform. In this way, the height of each first support platform can be adjusted by driving the rotation speed and direction of each drive shaft 21, making the height control and adjustment of the wet paper towel 100 supported on the first support platform more accurate and the operation simpler. The height adjustment of the paper receiving annular belt 23 can be adjusted by controlling the rotation speed of the drive shaft 21. Since there is only the lifting control of the first support platform, the operation skill requirements of the operator are low, reducing the labor intensity of the operator.

[0024] In some embodiments, the paper receiving assembly further includes a secondary support 24 fixedly connected to the main support 1. The drive shaft 21 and the driven shaft 22 are rotatably assembled on the secondary support 24. By setting the secondary support 24 and assembling the drive shaft 21 and the driven shaft 22 on the secondary support 24 respectively, the relative positions of the drive shaft 21 and the driven shaft 22 can be ensured to be accurate and reliable.

[0025] In some embodiments, each of the paper-receiving ring belts 23 is further provided with a second paper-receiving arm 232, and each of the second paper-receiving arms 232 in the two paper-receiving assemblies can also jointly form a second support platform for the wet paper towel 100. The first support platform and the second support platform can alternately support and adjust the height of the wet paper towel 100, which can speed up the working rhythm of the paper-receiving device and improve the working efficiency.

[0026] The aforementioned first paper receiving arm 231 and second paper receiving arm 232 can be integrally formed with the paper receiving ring belt 23, for example, by polyurethane plastic injection molding.

[0027] In some embodiments, the two auxiliary supports 24 form a receiving space for the wet tissue 100 on opposite sides. A tissue guide structure (not shown in the figure) is provided at the top opening of the receiving space to guide the wet tissue 100 as it falls into the receiving space, ensuring the accurate positioning of the wet tissue 100. See details. Figure 1 As shown, in some embodiments, the tissue guide structure includes a plurality of guide rods 3 spaced apart along the axial direction of the drive shaft 21. Each guide rod 3 is fixed to the sub-support 24. The top of each guide rod 3 on the two sub-supports 24 forms a flared structure that gradually expands from bottom to top. The aforementioned tissue guide structure is formed by using multiple spaced guide rods 3, which can reduce the contact area between the tissue and the wet tissue 100, thereby improving the smoothness of the wet tissue 100 during the falling guidance process.

[0028] In some embodiments, the axial distance between the drive shaft 21 and the driven shaft 22 can be adjusted to ensure reliable tension of the paper receiving annular belt 23, reliable meshing between the drive shaft 21 and the paper receiving annular belt 23, and thus ensure the positional accuracy of each first paper receiving arm 231 and second paper receiving arm 232 on the paper receiving annular belt 23.

[0029] In some embodiments, the two axial ends of the driven shaft 22 are connected to the main support 1 and the auxiliary support 24 via a spacing adjustment member 221. The aforementioned spacing adjustment member 221 can be, for example, a set bolt, which is threaded to the main support 1 or the auxiliary support 24, and its end abuts against the axial end of the driven shaft 22 corresponding to the position. In this way, force can be applied to the driven shaft 22 by tightening the set bolt, thereby adjusting the spacing between the driven shaft 22 and the driving shaft 21.

[0030] In some embodiments, the secondary support 24 is a plate, and the main support 1 includes a first plate 11 arranged parallel to and spaced apart from each of the secondary supports 24, and a second plate 12 fixedly connected to a first side of the first plate 11. The first plate 11 and the second plate 12 form an L-shaped structure, and the secondary support 24 is fixedly connected to the side of the second plate 12 close to the first plate 11. This makes the structure of the paper receiving device more reasonable and simple.

[0031] In some embodiments, the paper receiving device further includes a driving component, which is assembled on the main support 1. One driving component can drive each drive shaft 21 in the two paper receiving assemblies to rotate synchronously in opposite directions. By using one driving component to simultaneously drive the synchronous reverse rotation of the two drive shafts 21, the structural design of the device can be further simplified.

[0032] See further Figure 1 As shown, in some embodiments, the driving component includes a rotary motor 41 with a reducer, a direction adjustment wheel 42, and a drive timing belt 43 that is simultaneously tensioned and wrapped around the output shaft of the reducer (specifically equipped with a drive pulley, not labeled in the figure), the direction adjustment wheel 42, and two drive shafts 21 (specifically, drive pulleys 211 fixedly connected to one end of the drive shaft 21). The rotary motor 41 is assembled on the side of the first plate 11 away from the paper receiving assembly, and the direction adjustment wheel 42 and the drive timing belt 43 are assembled on the side of the second plate 12 away from the paper receiving assembly. Specifically, the wrap angle formed by the aforementioned drive timing belt 43 at the aforementioned direction adjustment wheel 42 is on the same side as the wrap angle on the drive pulley 211 of one drive shaft 21 away from the rotary motor 41, while the wrap angle on the drive pulley 211 of one drive shaft 21 close to the rotary motor 41 is on the other side. In this way, the same drive timing belt 43 achieves synchronous reverse drive of the two drive shafts 21.

[0033] According to an embodiment of the present invention, a wet wipe folding machine is also provided, including the above-described paper receiving device.

[0034] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

[0035] 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.
