[0035] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0036] A pull-out wet wipes folding and receiving device, the structure of which can be Figures 1-8 For illustration. In this embodiment, the pull-out wet wipe folding and joining device includes: a cloth joining and interrupting unit, a cutting and folding unit and a discharge conveyor belt 2, wherein the cloth joining and interrupting unit includes two cloth joining and interrupting components arranged in a mirror image, and a cloth joining and discharge channel 11 is formed between the two cloth joining and interrupting components, and the discharge conveyor belt 2 is arranged below the cloth joining and discharge channel 11, and the cutting and folding unit is arranged above the cloth joining and discharge channel 11. When in use, the wet wipes raw material will first enter the cutting and folding unit for cutting and alternating folding. The wet wipes raw material that has completed alternating folding will enter the cloth joining and discharge channel, and will be received and interrupted by the cloth joining and interrupting unit to form stacked wet wipes products, and finally the wet wipes products will be sent to the subsequent packaging equipment by the discharge conveyor belt 2 for subsequent processing of the wet wipes products.

[0037] like Figure 1As shown, the cutting and folding unit in this embodiment includes a stationary blade roller 3, a rotating blade roller 4, and two rotating folding rollers 5. During assembly, the stationary blade roller 3 should be fixedly connected to the machine frame, while the rotating blade roller 4 and the two rotating folding rollers 5 should be rotatably mounted within the frame. After assembly, a cutting gap should be formed between the stationary blade roller 3 and the rotating blade roller 4, and a folding gap should be formed between the two rotating folding rollers 5, connecting to the fabric receiving and discharging channel 11.

[0038] In order to realize the cutting of wet wipes raw materials, such as Figure 2 As shown, the device is provided with a cutting top knife 31 on the fixed guide roller and a cutting bottom knife 41 on the rotating knife roller 4. Therefore, when the wet wipes raw material passes through the cutting gap, the rotation of the rotating knife roller 4 can enable the cutting bottom knife 41 and the cutting top knife 31 to cut the wet wipes raw material.

[0039] In order to achieve the alternate folding of wet wipes raw materials, such as Figure 3 As shown, the device is provided with a plurality of knife-clamping grooves and a plurality of knife-inserting grooves arranged alternately along the circumferential direction of each rotating folding roller 5 on the side wall thereof. A knife-clamping assembly is provided inside each knife-clamping groove, and a clamping gap for clamping the wet wipes is formed between the knife-clamping assembly and the inner side wall of the knife-clamping groove, and a knife-inserting block 7 for pushing the wet wipes into the clamping gap of the other rotating folding roller 5 is provided in the knife-inserting groove of any rotating folding roller 5. When the wet wipes raw material is cut, the two rotating folding rollers 5 can guide and restrain the wet wipes raw material to ensure that the wet wipes raw material enters the folding gap smoothly. After the wet wipes raw material enters the folding gap, the two rotating folding rollers 5 will move relative to each other so that the wet wipes raw material can be alternately folded by the knife-clamping assembly and the knife-inserting block 7.

[0040] For example, Figure 3For example, when a blade assembly on the left rotating folding roller 5 enters the folding gap, a blade block 7 on the right rotating folding roller 5 will also enter the folding gap. At this time, the blade block 7 on the right rotating folding roller 5 will squeeze the wet wipe material inside the folding gap, causing the wet wipe material to bend. The bent portion of the wet wipe material will then be pushed into the clamping gap on the left rotating folding roller 5, thereby clamping and securing the bent portion with the clamping gap of the left rotating folding roller 5. As the two rotating folding rollers 5 continue to rotate, the wet wipes clamped and secured by the left rotating folding roller 5 will separate from the clamping gap, and a blade assembly on the right rotating folding roller 5 will enter the folding gap, and a blade block 7 on the left rotating folding roller 5 will also enter the folding gap. In this way, the blade block 7 on the left rotating folding roller 5 cooperates with the blade assembly on the right rotating folding roller 5 to bend the wet wipe material in opposite directions, and the bent portion can be clamped and secured with the clamping gap of the right rotating folding roller 5. In actual working process, the above process will be repeatedly performed between the two rotating folding rollers 5 for many times, thereby achieving the purpose of alternately folding the wet wipes raw materials by the device.

[0041] Alternatively, in this embodiment, both the top cutting blade 31 and the bottom cutting blade 41 may be straight cutting blades, so that the wet wipe material is cut in a straight line when passing through the cutting gap. Alternatively, the top cutting blade 31 may be configured as a toothed cutting blade, and the bottom cutting blade 41 may be configured as a straight cutting blade, so that the wet wipe material is cut in a dotted manner when passing through the cutting gap. Accordingly, the staff may also adjust the relative positions of the fixed blade roller 3, the rotating blade roller 4, and the rotating folding roller 5 according to actual needs, so that the relative relationship between the cutting position and the folding position on the wet wipe material meets actual usage requirements.

[0042] Figure 4 This is a schematic diagram of the knife clamp assembly in this embodiment. As shown in the figure, the knife clamp assembly may include: a knife clamp shaft 61, a connecting block 62, and a knife clamp block 63. The knife clamp shaft 61 is rotatably disposed within the knife clamp groove, the connecting block 62 is disposed at the end of the knife clamp shaft 61, and the knife clamp block 63 is disposed on the side wall of the knife clamp shaft 61, with a clamping gap formed between the knife clamp block 63 and the inner side wall of the knife clamp groove. During use, the rotation of the knife clamp shaft 61 can adjust the position of the knife clamp block 63, thereby controlling the opening and closing of the clamping gap to facilitate clamping or releasing the bent portion of the wet wipe material.

[0043] Optionally, in order to drive the clamping knife shaft 61 to rotate, the cutting and folding unit may further include two guide discs 8, which should be coaxially arranged with the two rotating folding rollers 5, and each guide disc 8 is provided with an action guiding section on the side wall near the folding gap. Figure 6As shown, the action guiding section may be provided with a first arc-shaped groove 81, a transition arc surface 82 and a second arc-shaped groove 83 arranged in sequence.

[0044] Correspondingly, the knife clamping assembly may further include a guide seat 64 and a guide wheel 65, wherein the guide seat 64 is arranged on the connecting block 62, and the guide wheel 65 is rotatably arranged on the guide seat 64. Figure 5 As shown, after the assembly is completed, the guide plate 8 can be fixed to the frame of the equipment through a mounting base (not shown in the figure), the side wall of the guide wheel 65 will contact the side wall of the guide plate 8, and when the folding roller 5 is rotated, the clamping knife assembly will move around the guide plate 8.

[0045] When the guide wheel 65 contacts the side wall of the guide disk 8, a clamping gap for accommodating wet wipes will be formed between the knife block 63 and the inner wall of the knife groove. When the knife clamp assembly enters the folding gap, the guide wheel 65 will enter the first arc-shaped groove 81. At this time, the rotation of the knife clamp shaft 61 will cause the knife clamp block 63 to move toward the inside of the knife clamp groove to facilitate clamping the bent part of the wet wipe. As the rotating folding roller 5 continues to rotate, the guide wheel 65 will contact the transition arc surface 82 to ensure that the wet wipes obtain a good clamping effect. When the knife clamp assembly is ready to leave the folding gap, the guide wheel 65 will contact the side wall of the guide disk 8 again through the guidance of the second arc-shaped groove 83. At this time, the knife clamp block 63 will move toward the outside of the knife clamp groove to facilitate the clamped wet wipes to separate from the cutting and folding unit.

[0046] It should be noted that in this device, the radius of curvature of the first arcuate groove 81 should be smaller than that of the second arcuate groove 83. Because the radius of curvature of the first arcuate groove 81 is smaller, the clamping blade assembly can rotate quickly as the guide wheel 65 enters the first arcuate groove 81, thereby promptly clamping the wet wipe. Conversely, because the radius of curvature of the second arcuate groove 83 is larger, the movement of the clamping blade assembly becomes smoother as the guide wheel 65 moves from the second arcuate groove 83 to the side wall of the guide plate 8, allowing the wet wipe to smoothly exit the cutting and folding unit.

[0047] As an optional implementation of this embodiment, to improve the movement precision of the blade clamping assemblies, a tension spring 9 may be installed between any two adjacent blade clamping assemblies on the same rotating folding roller 5. One end of the tension spring 9 should be connected to the guide seat 64, and the other end should be connected to the connecting block 62 of the adjacent blade clamping assembly. After the tension spring 9 is installed, the elastic force generated by the tension spring 9 can keep the guide wheel 65 in constant contact with the guide plate 8, ensuring that the blade clamping assembly moves according to the above-mentioned movement during actual operation.

[0048] Furthermore, to improve the reliability of wet wipe material conveyance within the cutting and folding unit, this embodiment further includes a first suction duct within the rotating blade roller 4 and a plurality of first suction holes 42 connected to the first suction duct on the sidewall of the rotating blade roller 4. A second suction duct may also be provided within the rotating folding roller 5, and a plurality of second suction holes 51 connected to the second suction duct on the sidewall of the rotating folding roller 5. During operation, a blower can be used to create a negative pressure within the first and second suction ducts. The suction generated by this negative pressure acts on the wet wipe material through the first and second suction holes 42 and 51, thereby improving the adhesion between the wet wipe material and the rotating blade roller 4 and rotating folding roller 5. Accordingly, since wet wipe material typically contains a certain amount of water, liquid barriers (such as sponge pads or liquid collection pipes) should also be provided within the first and second suction ducts to prevent moisture from entering the blower.

[0049] After the wet wipes raw materials have been cut and alternately folded, the cloth-receiving and interrupting unit will take over and interrupt them. Figure 7 and Figure 8 Used to illustrate the specific structure of the cloth receiving and breaking unit, as shown in the figure, in this embodiment, the cloth receiving and breaking component may include: a lifting frame 12, an action profile 13 and a cloth cutting shaft 14, wherein the action profile 13 is slidably set on the lifting frame 12, and the sliding direction of the action profile 13 should be perpendicular to the cloth receiving and discharging channel 11, and a plurality of cloth receiving strips 15 are provided on the action profile 13, and the cloth cutting shaft 14 is rotatably set on the action profile 13, and a plurality of cloth cutting strips 16 are provided on the side wall of the cloth cutting shaft 14, and the plurality of cloth cutting strips 16 and the plurality of cloth receiving strips 15 are alternately arranged one by one. During operation, the lifting and lowering action of the lifting frame 12 can adjust the height of the cloth strip 15. The sliding of the action profile 13 toward the cloth receiving and discharging channel 11 can insert the cloth strip 15 into the folded wet wipes to support the wet wipes. The rotation of the cloth cutting shaft 14 can cause the cloth cutting strip 16 to hit the wet wipes, so that the wet wipes are broken along the cutting part, completing the breaking process of the wet wipes. The cloth receiving and breaking components located on both sides of the cloth receiving and discharging channel 11 will perform actions alternately, so that the wet wipes raw materials that have been cut and alternately folded in the cloth receiving and discharging channel are formed into stacked wet wipes products, which are finally transported outward by the discharging conveyor belt 2.

[0050] It should be noted that, in order to achieve the lifting motion of the lifting frame 12, the present device should be provided with a driving component (such as a motor, etc.) for the lifting frame 12. Accordingly, to ensure that the lifting frame 12 and the action profile 13 have good motion accuracy, the present device should also be provided with a guide rail on the equipment frame for guiding the lifting frame 12, and a guide rail on the lifting frame 12 for guiding the action profile 13, so that the guide rails can guide and constrain the motion trajectory of the lifting frame 12 and the action profile 13.

[0051] Optionally, to drive the motion profile 13 to move, the fabric connection and breaking assembly may further include a drive motor 171 and a connecting rod 173. The drive motor 171 is mounted on the lifting frame 12. A first transmission rod 172 is disposed perpendicular to the output shaft of the drive motor 171. One end of the connecting rod 173 is hinged to the first transmission rod 172, and the other end is hinged to the motion profile 13. When the output shaft of the drive motor 171 rotates, the first transmission rod 172 and the connecting rod 173 convert the torque generated by the output shaft into a force applied to the motion profile 13, thereby driving the motion profile 13 to slide.

[0052] In addition, to drive the cloth cutting shaft 14 to move, a cloth cutting cylinder 181 may be provided on the actuating profile 13, and a second transmission rod 182 may be provided on the cloth cutting shaft 14, perpendicular to the cloth cutting shaft 14. The end of the second transmission rod 182, which is away from the cloth cutting shaft 14, should be hinged to the telescopic rod of the cloth cutting cylinder 181. When the telescopic rod of the cloth cutting cylinder 181 is extended and retracted, the second transmission rod 182 can convert the telescopic movement into a rotational torque acting on the cloth cutting shaft 14, thereby driving the cloth cutting shaft 14 to rotate.

[0053] The following describes the effects of the above scheme:

[0054] This embodiment provides a pull-out wet wipe folding and cloth-joining device that can constrain the wet wipes through two rotating folding rollers to ensure that the wet wipes can smoothly enter the folding gap. At the same time, the clamping knife assembly and the inserting knife block provided on the rotating folding roller can cooperate with each other to achieve the staggered folding processing of the wet wipes, and clamp and fix the bent parts of the wet wipes to prevent the wet wipes from separating from the rotating folding rollers. Secondly, this device can guide the movement of the clamping knife assembly through the guide plate, thereby controlling the opening and closing of the clamping gap, making it easier for the wet wipes to smoothly enter and exit the clamping gap. In addition, this device can also receive and break the wet wipes through the cloth-joining and breaking unit to form stacked wet wipes products, thereby improving the production efficiency of pull-out wet wipes.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
