Description

Technical Field

[0001] This invention relates to the field of wet wipe stacking technology, specifically to an automatic wet wipe stacking and conveying device. Background Technology

[0002] Wet wipes are disposable hygiene products made of nonwoven fabric, dust-free paper or other raw materials, used for daily cleaning. In the production process of wet wipes, after being cut, the wet wipes need to be stacked to a quantity that can be directly packaged. The existing stacking method is mostly to use a pressing block that can reciprocate, in conjunction with a rotating receiving ring. Based on the deformation of the wet wipes themselves, the pressing block presses the wet wipes from the hollow conveyor belt onto the receiving ring. Then, under the movement of the receiving ring, the wet wipes are placed on the conveyor belt below for transportation.

[0003] However, in practical applications, the following problems exist. First, the spacing of the hollow conveyor belt is difficult to adjust, resulting in poor adaptability to different sizes of wet wipes. When transporting larger wet wipes, the pressure pad will cause the edges of the wet wipes to lift up significantly during the pressing process, making the wet wipes unstable during subsequent transportation. Furthermore, during the flattening or packaging process, the upper side of the wet wipes may be folded. On the other hand, smaller wet wipes have a small contact area with the edge of the conveyor belt, making them unstable during transportation and possibly unable to support small wet wipes at all.

[0004] In addition, due to the way wet wipes are pressed down, the edges of the wet wipes may curl up. This curling up will affect the stability of the wet wipes during transportation. Depending on the manufacturing process, the top of the wet wipes is usually flattened before weighing or packaging. However, before flattening, the wet wipes need to undergo a long transportation process. Moreover, this flattening method is mostly done by vertical pressure or by squeezing. For wet wipes with severe curling, the top of the wet wipe may fold or become skewed during the flattening process. To solve the above problems, we have proposed an automatic stacking and conveying device for wet wipes. Summary of the Invention

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figure 1-11 The present invention provides a technical solution: an automatic stacking and conveying device for wet wipes, including a mounting base 1, a wet wipe conveyor belt 2 fixedly mounted on the mounting base 1, a movable support 3 movably mounted on the mounting base 1, and a conveyor belt 4 movably mounted on the upper side of the movable support 3.

[0039] The reciprocating mechanism 5 includes a first mounting frame 501, a reciprocating rod 506 and a fixed bracket 507. The fixed bracket 507 is fixedly mounted on the mounting base 1. The first mounting frame 501 is movably mounted on the fixed bracket 507. The reciprocating rod 506 is movably inserted into the first mounting frame 501.

[0040] The pressing mechanism 6 includes a second mounting frame 601 and a pressing rod 605. The second mounting frame 601 is mounted on the lower side of the reciprocating rod 506, and the pressing rod 605 is movably mounted inside the second mounting frame 601.

[0041] The spacing adjustment mechanism 7 includes a connecting horizontal plate 705 and a second hinge rod 706. The connecting horizontal plate 705 is fixedly installed on the lower side of the movable bracket 3, and the second hinge rod 706 is hinged to the connecting horizontal plate 705.

[0042] Transmission mechanism 8 includes mounting bracket 801 and flower shaft connecting rod 802. Mounting bracket 801 is fixedly mounted on mounting base 1, and two sets of flower shaft connecting rod 802 are rotatably mounted on mounting bracket 801.

[0043] Smoothing mechanism 9 includes a third mounting frame 901 and a smoothing rod 904. The third mounting frame 901 is movably mounted on the fixed bracket 507, and the smoothing rod 904 is movably disposed on the third mounting frame 901.

[0044] Both sets of movable brackets 3 are rotatably mounted with limit shafts 10, and drive shafts 11 are rotatably mounted on the lower side of the limit shafts 10. Both the limit shafts 10 and the drive shafts 11 are fitted with receiving belts 12, and two sets of protrusions are fixedly mounted on the receiving belts 12. A fourth drive motor 13 is fixedly mounted on one side of one set of movable brackets 3, and the output shaft of the fourth drive motor 13 is connected to the drive shaft 11.

[0045] This equipment utilizes an adjustable-spacing conveyor belt 4 to accommodate wet wipes of different sizes, enhancing its functionality. Furthermore, the equipment features a centrally located reciprocating mechanism 5 and a pressing mechanism 6, ensuring that their operation is unaffected by adjustments to the conveyor belt 4's spacing. A separate transmission mechanism 8 eliminates the need for additional power sources for transmission between different sets of conveyor belts 4 and the receiving belt 12, saving energy and ensuring synchronization of all components during operation. Additionally, the equipment includes a smoothing mechanism 9 to flatten stacked wet wipes, effectively preventing the edges of the wipes from lifting off the conveyor belt 2.

[0046] Furthermore, the spacing adjustment mechanism 7 includes a fixed horizontal plate 701, a first pulley 702, a connecting side plate 703, a second drive motor 704, a connecting horizontal plate 705, a second hinge rod 706, a connecting block 707, a second threaded sleeve 708, a mounting block 709, a bidirectional screw 710, and a third drive limiter 711. The fixed horizontal plate 701 is positioned at the center of the conveyor belt 4. The movable bracket 3 is fixedly connected to the fixed horizontal plate 701. The first pulley 702 is rotatably mounted on both ends of the fixed horizontal plate 701. The conveyor belt 4 is sleeved on the first pulley 702. Connecting side plates 703 are fixedly mounted on both sides of the ends of the fixed horizontal plate 701. The first pulley 702 is rotatably mounted between the connecting side plates 703. A second drive motor 704 is fixedly mounted on the connecting side plate 703. The output shaft of the second drive motor 704 is fixedly mounted on the first pulley 702. Two sets of second hinge rods 706 are hinged to a connecting horizontal plate 705. The two sets of second hinge rods 706 on the front and rear sides are hinged to connecting blocks 707. A second threaded sleeve 708 is fixedly mounted on each of the two sets of connecting blocks 707. Two sets of mounting blocks 709 are fixedly mounted on the mounting base 1. A bidirectional screw 710 is rotatably mounted between the mounting blocks 709. The second threaded sleeves 708 are threaded onto the bidirectional screw 710. A third drive limit 711 is fixedly mounted on a set of mounting blocks 709. The output shaft of the third drive limit 711 is connected to the bidirectional screw 710. A schematic diagram of this structure is shown below. Figure 3 and Figure 10 Its core function is to flexibly adjust the spacing between the two sets of conveyor belts 4. In traditional designs, the conveyor belts 4 are usually fitted onto a single structure, making it impossible to adjust their spacing. When directly adjusting the position of the conveyor belts 4 to accommodate different sizes of wet wipes, the adjustment range is limited by the installation position of the receiving belt 12. This device adopts a design where the conveyor belts 4 and the receiving belt 12 are completely separated, completely eliminating positional limitations during adjustment and significantly increasing the range of motion of the conveyor belts 4. This design not only ensures the stability of the device after adjustment but also simplifies the adjustment logic and operation, allowing operators to more easily perform programming control and greatly improving the device's adaptability and practicality for different sizes of wet wipes.

[0047] Furthermore, the spacing adjustment mechanism 7 includes a third limiting frame 712, a sliding block 713, and sliding wheels 714. The third limiting frame 712 is fixedly installed at each of the four corners of the mounting base 1. A sliding block 713 is fixedly installed on the lower side of the movable bracket 3. The shape of the third limiting frame 712 matches the shape of the sliding block 713. The sliding block 713 is slidably installed within the third limiting frame 712, and sliding wheels 714 are rotatably mounted in an array within the sliding block 713. A schematic diagram of this structure is shown below. Figure 6The lower side of the movable support 3 does not directly contact the mounting base 1, and the provided sliding wheel 714 further reduces the resistance when the movable support 3 moves. The length of the sliding block 713 is exactly the same as the width of the movable support 3. By abutting against the groove in the third limiting frame 712, it not only limits the lateral displacement of the movable support 3 but also enhances the stability of the movable support 3 during movement. This design ensures the flexibility of the movable support 3 adjustment and improves the overall operational stability of the equipment through the physical limiting structure.

[0048] Furthermore, the reciprocating mechanism 5 includes a first mounting frame 501, a turntable 502, a first drive motor 503, a first hinge rod 504, a first limiting frame 505, a reciprocating rod 506, a fixed bracket 507, a limiting block 508, a second limiting frame 509, a first threaded sleeve 510, and a first screw 511. The turntable 502 is rotatably mounted inside the first mounting frame 501, and the first drive motor 503 is fixedly mounted inside the first mounting frame 501. The output shaft of the first drive motor 503 is connected to the turntable 502, and the first hinge rod 504 is rotatably mounted on the turntable 502. A first limiting frame 505 is fixedly installed on the lower side of the first mounting frame 501. A reciprocating rod 506 is hinged to the lower side of the first hinge rod 504. The reciprocating rod 506 is movably inserted into the first limiting frame 505. A second limiting frame 509 is fixedly installed on the rear side of the first mounting frame 501. A limiting block 508 is fixedly installed on the upper side of the fixed bracket 507. A first threaded sleeve 510 is arrayed on the limiting block 508. The second limiting frame 509 is movably sleeved on the limiting block 508. A first screw 511 is movably inserted into the second limiting frame 509. The first screw 511 is threadedly installed into the first threaded sleeve 510. A schematic diagram of this structure is shown below. Figure 4 The structure within the first mounting frame 501 adopts a conventional design in the field of automatic wet wipe stacking, and its outer shell can protect the internal structure in high-humidity environments. In traditional designs, the reciprocating mechanism 5 is usually located on the side of the conveyor belt 4. However, if the reciprocating mechanism 5 is located on the side, when the spacing of the conveyor belt 4 is adjusted, the position of the pressing mechanism 6 will deviate from the center of the spacing between the two sets of conveyor belts 4, resulting in uneven force on the wet wipes during transport and causing them to tilt when they finally land on the wet wipe conveyor belt 2. This device avoids the above problem by centrally positioning the reciprocating mechanism 5, which will press the wet wipes to their center position regardless of their size. In addition, the first mounting frame 501 can also be height-adjusted to accommodate the stacking requirements of wet wipes of different thicknesses, further improving the applicability of the equipment.

[0049] Furthermore, the pressing mechanism 6 includes a second mounting frame 601, a connecting arc plate 602, a first gear 603, a second gear 604, and a pressing rod 605. The connecting arc plate 602 is fixedly mounted on the upper side of the second mounting frame 601, and the connecting arc plate 602 is fixedly mounted on the lower side of the reciprocating rod 506. Two sets of first gears 603 and two sets of second gears 604 are rotatably mounted inside the second mounting frame 601. The two sets of first gears 603 mesh with each other, and the two sets of second gears 604 mesh with each other. A pressing rod 605 is fixedly mounted between the first gear 603 and the second gear 604 on the same side. A schematic diagram of this structure is shown below. Figure 5 The pressing rod 605 is long and rod-shaped, with shear components fixedly mounted on its surface. This design ensures the stability and structural strength of the pressing rod 605 during long-term reciprocating motion. The two sets of pressing rods 605, through their interlocking structure, can achieve synchronous opening, facilitating precise adjustment of the distance between them. Furthermore, as the core component directly contacting the wet wipes, the pressing rod 605 is positioned away from the rest of the equipment. This layout effectively reduces the impact of humidity on the reciprocating mechanism 5 and the pressing mechanism 6, thereby improving the stability of the equipment during operation.

[0050] Furthermore, the pressing mechanism 6 includes a sleeve 606, a movable rod 607, a spring 608, a first limiting hole 609, a limiting rod 610, a second limiting hole 611, and a ring 612. The sleeve 606 is fixedly installed inside the second mounting frame 601. The movable rod 607 is movably inserted into the sleeve 606, and the spring 608 is sleeved on the movable rod 607. The second gear 604 has evenly spaced first limiting holes 609. The second mounting frame 601 has three sets of second limiting holes 611. The movable rod 607 is movably inserted into the upper second limiting hole 611. One end of the movable rod 607 is fixedly installed with a limiting rod 610. The limiting rod 610 passes through the second limiting hole 611 and is inserted into the first limiting hole 609. A ring 612 is fixedly installed on the limiting rod 610. A schematic diagram of this structure is shown below. Figure 5 Its function is to limit the rotation angle of the pressing rod 605. The sleeve 606 is located between the first gear 603 and the second gear 604, but not on the movement path of the first gear 603 and the second gear 604. This layout design effectively improves the space utilization of the pressing mechanism 6 and avoids motion interference between components. At the same time, through the limiting effect of parts such as the sleeve 606 on the pressing rod 605, the opening angle of the pressing rod 605 can be easily adjusted, ensuring stable pressing of wet wipes under different working conditions, and further optimizing the practicality and flexibility of the device;

[0051] Furthermore, the transmission mechanism 8 includes a mounting bracket 801, a spiral shaft connecting rod 802, a spiral shaft sleeve 803, a first mounting groove 804, a first bevel gear 805, and a second bevel gear 806. Two sets of spiral shaft sleeves 803 are movably sleeved on each of the two sets of spiral shaft connecting rods 802. The upper spiral shaft sleeve 803 is fixedly connected to different sets of first pulleys 702, while the lower spiral shaft sleeves 803 are rotatably mounted on the movable bracket 3. Each movable bracket 3 has a first mounting groove 804. A first bevel gear 805 is fixedly mounted on the rotating shaft of the drive shaft 11, and a second bevel gear 806 is fixedly mounted on the lower spiral shaft sleeve 803. Both the first bevel gear 805 and the second bevel gear 806 are located within the first mounting groove 804 and mesh with each other. A schematic diagram of this structure is shown below. Figure 7 , Figure 9 and Figure 11 Through the design of the transmission mechanism 8, the movement of the two sets of conveyor belts 4 and the receiving belt 12 can be achieved by the same set of corresponding motors. The transmission mechanism 8 adopts a combination transmission method of the spiral shaft connecting rod 802 and the spiral shaft sleeve 803, which can flexibly adapt to the spacing adjustment requirements of the conveyor belts 4, ensuring that the transmission continuity is maintained when the spacing of the conveyor belts 4 changes, and avoiding transmission interruption. This integrated transmission design means that the separate conveyor belts 4 and receiving belts 12 do not need to be equipped with separate main drive motors. Only one motor is needed to complete the coordinated movement of multiple sets of components. By reducing the number of motors, not only is the energy consumption of the equipment reduced, but the complexity of the transmission system is also simplified, the synchronization and stability of the equipment operation are improved, and the efficiency and energy saving of the automatic stacking and conveying process of wet wipes are further optimized.

[0052] Furthermore, the smoothing mechanism 9 includes a third mounting frame 901, second pulleys 902, a movable belt 903, and a smoothing rod 904. Two sets of third mounting frames 901 are mounted on the fixed bracket 507, with one end of each set facing the other. The third mounting frames 901 are located above the wet wipe conveyor belt 2. Two sets of second pulleys 902 are rotatably mounted inside the third mounting frames 901. A movable belt 903 is sleeved on each second pulley 902, and a smoothing rod 904 is fixedly mounted on the movable belt 903. The length of the smoothing rod 904 is less than the distance between the second pulleys 902. A schematic diagram of this structure is shown below. Figure 8 The smoothing rods 904 are designed with a relative motion pattern. Both sets of smoothing rods 904 converge from the center of the upper side of the wet wipe conveyor belt 2 and then extend outwards in parallel, thus achieving comprehensive smoothing of the stacked wet wipes. During operation, the smoothing rods 904 contact the wet wipes in a top-down pressing manner, and the two sets of smoothing rods 904 move in opposite directions. This design ensures that the smoothing rods 904 apply pressure only to the current layer of wet wipes when smoothing them, without carrying away the wet wipes on the upper side, effectively avoiding displacement or scattering problems during the stacking process.

[0053] Furthermore, the smoothing mechanism 9 includes a third drive motor 905 and a long-shaft gear 906. The centers of the opposite ends of the two sets of third mounting frames 901 are staggered. A third drive motor 905 is fixedly mounted on one set of third mounting frames 901. The output shaft of the third drive motor 905 is fixedly connected to the second pulley 902. A long-shaft gear 906 is fixedly mounted on each of the second pulleys 902 at the opposite ends of the third mounting frames 901. One end of the long-shaft gear 906 is rotatably mounted on the opposite third mounting frame 901, and the two sets of long-shaft gears 906 mesh with each other. A schematic diagram of this structure is shown below. Figure 8 Through the transmission design, different sets of second pulleys 902 can transmit power, thereby causing different sets of movable belts 903 to form opposite motion paths, thus efficiently smoothing the stacked wet wipes. Two sets of meshing long-shaft gears 906 not only perform the transmission function but also connect the two sets of third mounting frames 901. This design enhances the structural integrity of the smoothing mechanism 9.

[0054] Furthermore, the smoothing mechanism 9 includes a movable groove 907, a connecting bracket 908, a guide hole 909, a guide rod 910, a third threaded sleeve 911, a second screw 912, a second mounting groove 913, and a hexagonal block 914. All components are fixedly mounted on the connecting bracket 908 on the third mounting frame 901. The fixed bracket 507 has a movable groove 907, and the connecting bracket 908 moves within the movable groove 907. Guide holes 909 are provided on both sides of the connecting bracket 908, and the movable groove 907 has guide holes 909 on both sides. A guide rod 910 is fixedly installed and inserted into a guide hole 909. A third threaded sleeve 911 is fixedly installed at the center of the upper end of the connecting bracket 908. A second screw 912 is rotatably installed at the center of the movable groove 907. The third threaded sleeve 911 is threaded onto the second screw 912. A second mounting groove 913 is provided on the fixed bracket 507. A hexagonal block 914 is rotatably installed in the second mounting groove 913 and is fixedly connected to the second screw 912.

[0055] A schematic diagram of the structure is shown below. Figure 8 This structure allows for adjustment of the specific position of the third mounting frame 901. By adjusting the position of the third mounting frame 901, it can accommodate wet wipes of different thicknesses after stacking. When the thickness of the wet wipes varies, adjusting the position of the third mounting frame 901 ensures that the smoothing rod 904 contacts the wet wipes with appropriate force and position, thereby achieving a better smoothing effect. This not only enhances the functionality of the equipment, enabling it to handle the smoothing of wet wipes of different thicknesses, but also reduces problems such as equipment shaking or uneven smoothing caused by improper positioning due to the precise adjustment of the position, thus increasing the stability of the equipment during use.

[0056] Working principle: When in use, the second drive motor 704 starts and drives the first pulley 702 to rotate, thereby driving the transport belt 4 to rotate. The transport belt 4 transports the cut wet wipes. When the wet wipes are transported to the upper side of the receiving belt 12, the first drive motor 503 starts and drives the turntable 502 to rotate, thereby causing the first hinge rod 504 to rotate and drive the reciprocating rod 506 to reciprocate within the first limit frame 505, thereby driving the pressing rod 605 to press down, so that the wet wipes are deformed and fall onto the protrusion of the receiving belt 12. Then, the receiving belt 12 rotates and supports the wet wipes to a certain thickness. After that, the protrusion of the receiving belt 12 rotates to the lower side. On the side, the wet wipes fall onto the wet wipe conveyor belt 2 and are transported by it. The wet wipe conveyor belt 2 is a commonly used piece of equipment in wet wipe production, and its working principle will not be elaborated here. When the wet wipes are transported to the lower side of the smoothing mechanism 9, the third drive motor 905 will drive a set of second pulleys 902 to rotate, and through the meshing between the long shaft gears 906, drive different sets of second pulleys 902 to rotate, so that the movable belt 903 can rotate in the opposite direction, so that the smoothing rod 904 rotates to the lower side and presses against the center position of the upper end of the wet wipe layer, and extends horizontally outward as the movable belt 903 moves, thereby achieving the smoothing of the wet wipes.

[0057] When adjusting the height of the third mounting frame 901, the hexagonal block 914 is rotated using a wrench or other tools, which in turn drives the second screw 912 to rotate. The second screw 912 drives the connecting bracket 908 to rise or fall through the thread action between it and the third screw sleeve 911. At this time, the guide rod 910 is inserted into the guide hole 909 so that the connecting bracket 908 can move stably.

[0058] When it is necessary to adjust the spacing of the conveyor belt 4, the third drive limit 711 is activated to drive the bidirectional screw 710, thereby driving the connecting block 707 to move in opposite directions through the thread action between the screw and the second screw sleeve 708, so that the second hinge rod 706 gradually becomes vertical or horizontal, thereby driving the two sets of movable brackets 3 to move in opposite directions. At this time, the sliding block 713 slides in the groove of the third limit frame 712.

[0059] When adjusting the distance between the transport belt 4 and the movable bracket 3, the flower shaft sleeve 803 will move relative to the flower shaft connecting rod 802, but will maintain the transmission between the different first pulleys 702 and drive the drive shaft 11 to rotate synchronously through the meshing between the first bevel gear 805 and the second bevel gear 806.

[0060] When adjusting the height of the first mounting frame 501, rotate the first screw 511 out, and then move the second limiting frame 509 along the limiting block 508. After moving to the appropriate position, screw the first screw 511 into the corresponding first screw sleeve 510.

[0061] When adjusting the opening angle of the pressing rod 605, pull the ring 612 to disengage the limiting rod 610 from the first limiting hole 609 and the second limiting hole 611. Then adjust the opening angle of the pressing rod 605. At this time, the two sets of pressing rods 605 open synchronously through the meshing between the two sets of first gears 603 and the two sets of second gears 604. Then release the movable rod 607. Under the rebound of the spring 608, the limiting rod 610 can be re-inserted into the second limiting hole 611 and the first limiting hole 609.
