Description

Technical Field

[0001] This utility model relates to the field of cutting technology, specifically to a cutting structure for folding wet wipes. Background Technology

[0002] The wet wipe folding machine conveys the zig-folded wet wipes to the cutting table, where they are cut by a cutter. During the cutting process, it is important to ensure that the edges of the wet wipes are neat and smooth.

[0003] During the cutting process, the cutter applies pressure to the wet wipes, which causes them to deform and squeeze out some of the liquid, especially near the cut edge. This part currently receives less attention.

[0004] This solution proposes a knife-cutting structure for folding wet wipes, which replenishes the moisture at the cut edge of the wet wipe while cutting, balancing the moisture changes during the cutting process. Utility Model Content

[0005] (a) Technical issues

[0006] The present invention aims to at least solve the problem in the prior art that wet wipes lose some moisture when cut due to the pressure of the cutter.

[0007] (II) Technical Content

[0008] This solution provides a knife-cutting structure for folding wet wipes, achieved through the following specific technical means, including:

[0009] The cutting table is connected to the folding mechanism, which pushes the folded wet wipes onto the cutting table.

[0010] The mounting frame has a cutting table fixed in the base frame. A cutter is rotatably mounted on the top of the mounting frame above the cutting table, and the lower middle part of the cutter protrudes from a slit in the cutting table.

[0011] The humidifying station is fixed on the cutting table and located behind the seam. The humidifying station contacts the cut edge of the wet wipe and provides appropriate humidification to the cut edge.

[0012] Preferred technical solution 1: Atomizing nozzles are installed in the inner cavity of the partitioned humidification table, and the two side walls of the partitioned humidification table are set as mesh surfaces through which atomized water can pass. When the cut of the wet wipe passes through the mesh, it absorbs the discharged atomized water, thereby replenishing the water in the cut.

[0013] Preferred technical solution 2: A blade cover is also fixed on the mounting bracket, covering the upper middle part of the cutter. A blade deformation detection module is set inside the blade cover, which is used to detect the deformation of the blade edge.

[0014] Preferred technical solution 3: There are limit baffles on both the left and right sides of the cutting table, and the tail ends of the two sets of limit baffles are parallel to the two side walls of the humidification table, so that the cut wet wipes can smoothly enter the two sets of sub-channels.

[0015] Preferred technical solution four: The bottom wall of the partitioned humidification table is provided with a drainage hole that penetrates the cutting table, which is used to drain the water accumulated in the partitioned humidification table.

[0016] (III) Technical Effects

[0017] The above structure gives this solution the following advantages:

[0018] 1. Use the partitioned humidification station on the cutting table to quickly replenish the water at the cut edges of the wet wipes after they have been cut by the cutter, in order to compensate for the water loss at the cut edges during the cutting process.

[0019] 2. Add ingredients as needed, overall moisture content is controllable;

[0020] 3. Monitor blade edge deformation to detect it promptly. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0029] Example 1, please refer to Figures 1-3 and Figure 5 ;

[0030] A cutting structure for folding wet wipes includes a cutting table 1, a mounting frame 3, a cutter 4, and a partitioned humidification table 5.

[0031] The cutting table 1 is fixed in the base frame, which provides support for the cutting table 1. The front end of the cutting table 1 is connected to the folding mechanism. The folding mechanism pushes the folded wet wipes onto the cutting table 1. The blade shaft of the cutter 4 is rotatably mounted on the top of the mounting frame 3 above the cutting table 1. When in use, the blade shaft is connected to the output shaft of the external power device. The external power device, such as the motor 62, provides power support for the rotation of the cutter 4. The lower middle part of the cutter 4 passes through the slit opened on the cutting table 1.

[0032] There are limit baffles 2 on both the left and right sides of the cutting table 1, and the distance between the two sets of limit baffles 2 is adapted to the width of the folded wet wipe.

[0033] The dividing humidification platform 5 is located on the rear side of the gap and is fixed on the cutting table 1. The dividing humidification platform 5 divides the middle and rear part of the cutting table 1 into two sets of sub-channels 51. At the same time, the tail ends of the two sets of limiting baffles 2 are also parallel to the two side walls of the dividing humidification platform 5, so that the cut wet wipes can smoothly enter the two sets of sub-channels 51. The wet wipes cut by the cutter 4 enter the two sets of sub-channels 51 respectively. At this time, the side wall of the dividing humidification platform 5 contacts the cut of the wet wipe. An atomizing nozzle (not shown in the figure) is installed in the inner cavity of the dividing humidification platform 5. The two side walls of the dividing humidification platform 5 are set as mesh surfaces 52 through which atomized water can pass. When the cut of the wet wipe passes along the mesh surface 52, it absorbs the discharged atomized water, thereby replenishing the water at the cut and humidifying the cut. The humidification amount is set according to the results of multiple tests.

[0034] Rehydrating immediately after cutting can effectively replenish the moisture lost from the cut and maintain the overall humidity balance of the wipes. If you choose to rehydrate after a longer interval, the moisture in the wipes will have already flowed and balanced again. Rehydrating at this time requires overall hydration, which is more difficult to do.

[0035] The partitioned humidification table 5 has a triangular structure, with the apex of the triangle facing the cutting edge of the cutter 4 and close to the rear side of the cutter 4. The mesh plates are distributed in the middle and rear parts of the two side walls of the partitioned humidification table 5. The triangular structure makes the wet wipes move back more smoothly after being cut, and provides enough space for the installation of the atomizing nozzle.

[0036] The bottom wall of the partition humidification table 5 is provided with a drainage hole 11 that penetrates the cutting table 1, which is used to drain the water accumulated in the partition humidification table and prevent it from remaining in the inner cavity of the partition humidification table.

[0037] A water collection pool 31 is formed at the bottom of the mounting frame 3, which can not only collect water falling from the gaps, but also provide water for humidification. A delivery pump is installed in the chassis fixed on the mounting frame 3. The inlet pipe of the delivery pump extends into the water collection pool 31 to draw water, and the outlet pipe is connected to the atomizing nozzle to provide water to the atomizing nozzle. A filter 53 is installed at the end of the inlet pipe of the delivery pump to filter the water in the water collection pool 31 and prevent impurities from entering.

[0038] To ensure water quality, regular testing and replacement are necessary.

[0039] Example 2, based on Example 1, see [link / reference] Figure 2 ;

[0040] The distance between the two sets of limit baffles 2 is adjustable, which is achieved by adjusting the component 6;

[0041] The adjustment assembly 6 includes a double-ended lead screw 61 rotatably mounted on the mounting bracket 3. The middle part of the double-ended lead screw 61 passes through the transverse hole on the cutting table 1, and two sets of limiting baffles 2 are respectively sleeved on both ends of the double-ended lead screw 61 through threaded holes. The rotation of the double-ended lead screw 61 provides a pushing force for the sliding of the limiting baffles 2 on the cutting table 1.

[0042] To ensure stability during movement, multiple sets of double-ended lead screws 61 can be arranged in parallel. The ends of the multiple sets of double-ended lead screws 61 are fixed to the pulleys and connected by a transmission belt 63, thereby realizing the linkage between the multiple sets of double-ended lead screws 61. The other end of one set of double-ended lead screws 61 is connected to the shaft end of a motor 62 fixed on the mounting frame 3. This set of motors 62 provides a power source for the rotation of the multiple sets of double-ended lead screws 61, which is used to adjust the spacing between the two sets of limit baffles 2 according to the folding width of the wet wipe.

[0043] Example 3, based on Example 1 or Example 2, see [reference] Figures 1-2 ;

[0044] The mounting bracket 3 is also fixed with a blade cover 7, which covers the upper middle part of the cutter 4. During the cutting process, it is necessary to ensure that the edge of the wet wipe is neat and smooth. Therefore, it is necessary to ensure that the blade is not severely deformed. Therefore, a blade deformation detection module is set inside the blade cover 7. The blade deformation detection module is used to detect the deformation of the blade edge.

[0045] The blade deformation detection module is a distance sensor 8 fixedly installed on the inner wall of the blade cover 7. The distance sensor 8 faces the cutting edge of the cutter 4 and is used to measure the distance between the distance sensor 8 and the cutting edge. When the data changes beyond the set value, it can be determined that the cutting edge has been severely deformed.

[0046] For the ranging sensor 8, it is best to choose a commercially available sensor with wireless signal transmission and alarm functions. The testing accuracy should be selected according to actual needs.

[0047] Example 4, based on Example 1, Example 2 or Example 3, see [reference] Figure 4 ;

[0048] A blade wiping pad 9 is installed on the bottom side of the cutting table 1 and on both sides of the cutter 4. It is used to wipe and clean the fiber debris adhering to the blade, so as to achieve real-time cleaning of the cutter 4.

[0049] Furthermore, if necessary, blower heads 10 can be installed on the bottom of the cutting table 1 on both sides of the cutter 4 to clean the blade edge after use. The blower head 10 is connected to the air pump output pipe installed on the mounting bracket 3. The air pump provides the blower head 10 with downward airflow to blow off the debris adhering to the blade edge. The blower head 10 can be selected for activation time and frequency as needed.

[0050] It is worth noting that the motor 62, ranging sensor 8, delivery pump, air pump, and their matching power supply and control switch mentioned in this embodiment can also be provided by the manufacturer. The circuits, electronic components and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and there is no need to elaborate.

[0051] The parts not disclosed in this utility model are all prior art, and their specific structures and working principles will not be described in detail.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
