Description

Technical Field

[0001] The invention relates to the technical field of wet wipes stacking, and in particular to an automatic wet wipes stacking and conveying device. Background Art

[0002] Wet wipes refer to disposable sanitary products made of non-woven fabrics, dust-free paper or other raw materials, and are used for cleaning in daily life. In the process of wet wipe production, the wet wipes need to be stacked into a quantity that can be directly packaged after being cut. The existing stacking method is mostly through a cloth pressing block that can perform reciprocating motion and a rotating receiving ring. Based on the deformation of the wet wipes themselves, the cloth pressing block presses the wet wipes from the hollow conveyor belt to the receiving ring, and then under the movement of the receiving ring, the wet wipes are placed on the conveyor belt on the lower side for transportation.

[0003] However, in actual application, there are the following problems. First, the spacing of the hollow conveyor belt is difficult to adjust, which makes it difficult to adapt to wet wipes of different sizes. When transporting larger wet wipes, the cloth pressing block will cause the edge of the wet wipe to rise significantly during the downward pressing process, making the wet wipe unstable during the subsequent transportation process and the upper wet wipe may be folded during the flattening or packaging process. The contact area between the smaller wet wipes and the edge of the conveyor belt is small, which makes it unstable during transportation and may not be able to accommodate small wet wipes at all.

[0004] In addition, due to the way the wet wipes are pressed down, the edges of the wet wipes will be warped, which will affect the stability of the wet wipes during transportation. Depending on the production process, the upper side of the wet wipes will generally be flattened before weighing or packaging. However, before flattening, the wet wipes need to be transported over a long process, and this flattening method is mostly done through vertical pressure or squeezing. For wet wipes with severe warping, the upper side of the wet wipes may be folded, or may become skewed during the flattening process. For this reason, we have proposed an automatic stacking and conveying device for wet wipes to solve the above problems. Summary of the invention

[0021] This device realizes adaptive transportation of wet wipes of different sizes through the transport belt 4 with adjustable spacing, which enhances the functionality of the device when in use. In addition, the device is also provided with a central reciprocating mechanism 5 and a pressing mechanism 6, so that the reciprocating mechanism 5 and the pressing mechanism 6 are not affected by the spacing adjustment of the transport belt 4 during operation. The device is also provided with a transmission mechanism 8, which can make the transmission between different groups of transport belts 4 and receiving belts 12 without adding an additional power source, which not only saves energy but also ensures the synchronization of various parts during the operation of the equipment. At the same time, the smoothing mechanism 9 equipped with the equipment has the ability to smooth the stacked wet wipes, which can effectively prevent the corners of the wet wipes output from the wet wipes conveyor belt 2 from warping.

[0022] Furthermore, the spacing adjustment mechanism 7 includes a fixed transverse plate 701, a first pulley 702, a connecting side plate 703, a second drive motor 704, a connecting transverse plate 705, a second hinged rod 706, a connecting block 707, a second screw sleeve 708, a mounting block 709, a bidirectional screw 710 and a third drive limit 711. The fixed transverse plate 701 is arranged at the center position of the conveying belt 4, and the movable bracket 3 is fixedly connected to the fixed transverse plate 701. The first pulley 702 is rotatably installed at both ends of the fixed transverse plate 701. The conveying belt 4 is sleeved on the first pulley 702. The connecting side plates 703 are fixedly installed on both sides of the end of the fixed transverse plate 701. The first pulley 702 is rotatably installed between the connecting side plates 703.

The two groups of connecting blocks 707 are fixedly mounted with second screw sleeves 708. Two groups of mounting blocks 709 are fixedly mounted on the mounting base 1. Bidirectional screw rods 710 are rotatably mounted between the mounting blocks 709. The second screw sleeves 708 are all connected to the bidirectional screw rods 710 through threads. A third drive limiter 711 is fixedly mounted on a group of mounting blocks 709, and the output shaft of the third drive limiter 711 is connected to the bidirectional screw rod 710. The schematic diagram of the structure is as follows: Figure 3 and Fig.10 , its core function is to realize the flexible adjustment of the distance between the two sets of conveyor belts 4. In the traditional design, the conveyor belt 4 is usually sleeved on an integral structure, which makes it impossible to adjust its distance; and when the position of the conveyor belt 4 is directly adjusted to adapt to wet wipes of different sizes, its adjustment range will be limited by the installation position of the receiving belt 12, so that the adjustment range is limited. This equipment adopts a design in which the conveyor belt 4 is completely separated from the receiving belt 12, which completely removes the position restriction during the adjustment process and significantly increases the range of motion of the conveyor belt 4. This design not only ensures the stability of the equipment after adjustment, but also simplifies the adjustment logic and operation method, allowing staff to perform programming control more conveniently, greatly improving the equipment's adaptability and practicality for wet wipes of different sizes; Furthermore, the spacing adjustment mechanism 7 includes a third limit frame 712, a sliding block 713 and a sliding wheel 714. The third limit frame 712 is fixedly installed at the four corners of the mounting base 1, and the sliding block 713 is fixedly installed on the lower side of the movable bracket 3. The shape of the third limit frame 712 is adapted to the shape of the sliding block 713. The sliding block 713 is slidably installed in the third limit frame 712, and the sliding wheel 714 is rotatably installed in the sliding block 713. The schematic diagram of the structure is as follows: Figure 6, the lower side of the movable bracket 3 is not in direct contact with the mounting base 1, and the sliding wheel 714 provided can further reduce the resistance of the movable bracket 3 when it moves. The length of the sliding block 713 is completely consistent with the width of the movable bracket 3. By abutting against the groove in the third limit frame 712, it not only limits the lateral deviation of the movable bracket 3, but also enhances the stability of the movable bracket 3 during movement. This design not only ensures the flexibility of the adjustment of the movable bracket 3, but also improves the overall running stability of the equipment through the physical limit structure; Furthermore, the reciprocating mechanism 5 includes a first mounting frame 501, a rotating disk 502, a first driving motor 503, a first hinged 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 screw sleeve 510 and a first screw 511. The rotating disk 502 is rotatably mounted in the first mounting frame 501, the first driving motor 503 is fixedly mounted in the first mounting frame 501, the output shaft of the first driving motor 503 is connected to the rotating disk 502, the first hinged rod 504 is rotatably mounted on the rotating disk 502, and the first mounting frame 5 01 is fixedly installed with a first limit frame 505 on the lower side, a reciprocating rod 506 is hinged on the lower side of the first hinged rod 504, and the reciprocating rod 506 is movably inserted in the first limit frame 505. A second limit frame 509 is fixedly installed on the rear side of the first installation frame 501, and a limit block 508 is fixedly installed on the upper side of the fixed bracket 507. A first screw sleeve 510 is installed in an array on the limit block 508. The second limit frame 509 is movably sleeved on the limit block 508. A first screw rod 511 is movably inserted in the second limit frame 509, and the first screw rod 511 is threadedly installed in the first screw sleeve 510. The schematic diagram of the structure is as follows: Figure 4 , the structure inside the first installation frame 501 adopts the conventional design in the field of automatic stacking of wet wipes, and its outer shell can protect the internal structure in an environment with high humidity. In traditional designs, the reciprocating mechanism 5 is usually set on the side of the conveying belt 4, but if the reciprocating mechanism 5 is set on the side, when the spacing of the conveying belts 4 is adjusted, the position of the pressing mechanism 6 will deviate from the center of the spacing between the two groups of conveying belts 4, causing the wet wipes to be unevenly stressed during transportation, and eventually skewed when they fall on the wet wipes conveyor belt 2. However, this device avoids the above problems by arranging the reciprocating mechanism 5 in the center, so that the center position of the wet wipes will be pressed regardless of their size. In addition, the first installation frame 501 can also be adjusted in height to meet the stacking requirements of wet wipes of different thicknesses, further improving the applicability of the equipment; 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 groups of first gears 603 and two groups of second gears 604 are rotatably mounted in the second mounting frame 601. The two groups of first gears 603 mesh with each other, and the two groups 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. The schematic diagram of the structure is as follows: Figure 5 The pressing rod 605 is in the shape of a long rod, and a shear member is fixedly installed on its surface. This design can ensure the stability and structural strength of the pressing rod 605 during long-term reciprocating motion. The two sets of pressing rods 605 can realize synchronous opening action through the mutually meshing structural design, so as to facilitate the precise adjustment of the distance between the two sets of pressing rods 605. In addition, the pressing rod 605 is the core component that directly contacts the wet wipes, and the other parts of the equipment are not arranged directly above the wet wipes. This layout effectively reduces the erosion of humidity on the reciprocating mechanism 5 and the pressing mechanism 6, thereby improving the stability of the equipment during operation; 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 finger ring 612. The sleeve 606 is fixedly installed in the second installation frame 601, and the movable rod 607 is movably inserted in the sleeve 606. The spring 608 is sleeved on the movable rod 607. The first limiting holes 609 are arranged in an array on the second gear 604. Three groups of second limiting holes 611 are arranged on the second installation frame 601. The movable rod 607 is movably inserted in the second limiting hole 611 on the upper side. The limiting rod 610 is fixedly installed on one end of the movable rod 607. The limiting rod 610 passes through the second limiting hole 611 and is inserted in the first limiting hole 609. The finger ring 612 is fixedly installed on the limiting rod 610. The schematic diagram of the structure is as follows: Figure 5 , whose function is to limit the rotation angle of the pressing rod 605. The sleeve 606 is arranged between the first gear 603 and the second gear 604, but is not located on the movable 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 the movement interference between the components. At the same time, through the limiting effect of the sleeve 606 and other parts on the pressing rod 605, the opening angle of the pressing rod 605 can be easily adjusted, ensuring the stable pressing of the wet wipes by the equipment under different working conditions, and further optimizing the practicality and flexibility of the device; Furthermore, the transmission mechanism 8 includes a mounting bracket 801, a flower shaft connecting rod 802, a flower shaft sleeve 803, a first mounting groove 804, a first bevel gear 805 and a second bevel gear 806. Two groups of flower shaft connecting rods 802 are movably sleeved with two groups of flower shaft sleeves 803. The upper flower shaft sleeves 803 are fixedly connected to different groups of first pulleys 702. The lower flower shaft sleeves 803 are rotatably mounted on the movable bracket 3. The movable bracket 3 is provided with a first mounting groove 804. The first bevel gear 805 is fixedly mounted on the rotating shaft of the driving shaft 11. The second bevel gear 806 is fixedly mounted on the lower flower shaft sleeve 803. The first bevel gear 805 and the second bevel gear 806 are both arranged in the first mounting groove 804 and meshed with each other. The schematic diagram of the structure is as follows: Figure 7 , Fig. 9 and Fig.11 , through the design of the transmission mechanism 8, the movement of the two groups of transport belts 4 and the receiving belts 12 can be driven by the same group of corresponding motors. The transmission mechanism 8 adopts a combined transmission method of a flower shaft connecting rod 802 and a flower shaft sleeve 803, which can flexibly adapt to the spacing adjustment requirements of the transport belt 4, ensuring that the transmission continuity is maintained when the spacing of the transport belt 4 changes, avoiding transmission interruption. This integrated transmission design makes it unnecessary to configure independent main drive motors for the split transport belt 4 and the receiving belt 12. Only one set of motors is needed to complete the coordinated movement of multiple groups of components. By reducing the number of motors, not only the energy consumption of the equipment is reduced, but also the complexity of the transmission system is 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; Furthermore, the smoothing mechanism 9 includes a third mounting frame 901, a second pulley 902, a movable belt 903 and a smoothing rod 904. Two sets of third mounting frames 901 are arranged on the fixed bracket 507. One end of the two sets of third mounting frames 901 is opposite. The third mounting frame 901 is located on the upper side of the wet wipes conveyor belt 2. Two sets of second pulleys 902 are rotatably mounted in the third mounting frame 901. The movable belt 903 is sleeved on the second pulley 902. The smoothing rod 904 is fixedly mounted on the movable belt 903. The length of the smoothing rod 904 is less than the spacing between the second pulleys 902. The schematic diagram of the structure is as follows: Figure 8 The moving path of the smoothing rod 904 is designed as a relative motion mode. The two groups of smoothing rods 904 are concentrated from the central position on the upper side of the wet wipes conveyor belt 2 and then spread out in parallel, so as to achieve 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 groups of smoothing rods 904 are in a state of moving in opposite directions. This design ensures that the smoothing rods 904 only apply pressure to the current layer of wet wipes when smoothing the wet wipes, and will not take away the wet wipes on the upper side, effectively avoiding the problem of displacement or scattering of wet wipes during stacking; Furthermore, the smoothing mechanism 9 includes a third drive motor 905 and a long shaft gear 906. The centers of the two sets of third mounting frames 901 are staggered at the opposite ends. The third drive motor 905 is fixedly mounted on one set of the third mounting frames 901. The output shaft of the third drive motor 905 is fixedly connected to the second belt pulley 902. Long shaft gears 906 are fixedly mounted on the second belt pulley 902 in 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. The two sets of long shaft gears 906 are meshed. The schematic diagram of the structure is as follows: Figure 8 Through the transmission design, different groups of second pulleys 902 can realize power transmission, so that different groups of active belts 903 form opposite movement paths, so as to efficiently smooth the stacked wet wipes. The two groups of intermeshing long shaft gears 906 not only bear the transmission function, but also play the role of connecting the two groups of third mounting frames 901. This design enhances the structural integrity of the smoothing mechanism 9; Furthermore, the smoothing mechanism 9 includes a movable groove 907, a connecting bracket 908, a guide hole 909, a guide rod 910, a third screw sleeve 911, a second screw rod 912, a second mounting groove 913 and a hexagonal block 914. The third mounting frame 901 is fixedly mounted on the connecting bracket 908. The fixed bracket 507 is provided with a movable groove 907. The connecting bracket 908 moves in the movable groove 907. Guide holes 909 are provided on both sides of the connecting bracket 908. Both sides of the movable groove 907 A guide rod 910 is fixedly installed and inserted into the guide hole 909. A third screw sleeve 911 is fixedly installed at the center position of the upper end of the connecting bracket 908. A second screw rod 912 is rotatably installed at the center position of the movable groove 907. The third screw sleeve 911 is threadedly connected to the second screw rod 912. A second mounting groove 913 is opened on the fixed bracket 507. A hexagonal block 914 is rotatably installed in the second mounting groove 913. The hexagonal block 914 is fixedly connected to the second screw rod 912.

[0023] The schematic diagram of the structure is Figure 8 With the help of this structure, the specific position of the third mounting frame 901 can be adjusted. By adjusting the position of the third mounting frame 901, wet wipes of different thicknesses after stacking can be adapted. When the thickness of the wet wipes changes, reasonable adjustment of the position of the third mounting frame 901 can allow the smoothing rod 904 to contact the wet wipes with appropriate force and position, thereby achieving a better smoothing effect on the wet wipes. This not only enhances the functionality of the device during use, enabling it to handle the smoothing of wet wipes of different thicknesses, but also because the position can be accurately adjusted, it reduces problems such as equipment shaking or uneven smoothing due to improper position, and also increases the stability of the device during use.

[0024] Working principle: When the present invention is used, the second drive motor 704 starts to drive the first pulley 702 to rotate, thereby driving the transport belt 4 to rotate, and the cut wet wipes are transported on the transport belt 4. When the wet wipes are transported to the upper side of the receiving belt 12, the first drive motor 503 starts to drive the turntable 502 to rotate, so that the first hinged rod 504 rotates and drives the reciprocating rod 506 to reciprocate in the first limit frame 505, thereby driving the pressing rod 605 to press down, so that the wet wipes fall on the protrusion of the receiving belt 12 through deformation, and then the receiving belt 12 rotates while receiving the wet wipes to a certain thickness, and the protrusion of the receiving belt 12 rotates to the bottom On the side, the wet wipes fall onto the wet wipes conveyor belt 2 and are transported by the wet wipes conveyor belt 2. The wet wipes conveyor belt 2 is a commonly used equipment in the production of wet wipes, and its working principle is not 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 group of second pulleys 902 to rotate, and drive different groups of second pulleys 902 to rotate through the engagement between the long shaft gears 906, so that the movable belt 903 can rotate in the opposite direction, so that the smoothing rod 904 rotates to the lower side and is pressed against the center position of the upper end of the wet wipes layer, and moves horizontally and outwards with the movable belt 903, thereby achieving the smoothing of the wet wipes.

[0025] When adjusting the height of the third mounting frame 901, the hexagonal block 914 is rotated by a wrench or other tool, thereby driving the second screw 912 to rotate. The second screw 912 drives the connecting bracket 908 to rise or fall through the threaded action between the second screw 912 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.

[0026] When the spacing of the transport belt 4 needs to be adjusted, the third drive limit 711 is started to drive the bidirectional screw 710, thereby driving the connecting block 707 to move in opposite directions through the threaded action between the second screw sleeve 708, so that the second hinge rod 706 gradually becomes vertical or horizontal, thereby driving the two groups 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.

[0027] 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 engagement between the first bevel gear 805 and the second bevel gear 806.

[0028] When adjusting the height of the first installation frame 501 , the first screw rod 511 is rotated out, and then the second limit frame 509 is moved along the limit block 508 . After moving to a suitable position, the first screw rod 511 is screwed into the corresponding first screw sleeve 510 .

[0029] When adjusting the opening angle of the pressing rod 605, pull the finger ring 612 to disengage the limiting rod 610 from the first limiting hole 609 and the second limiting hole 611, and then adjust the opening angle of the pressing rod 605. At this time, the two groups of pressing rods 605 are synchronously opened through the engagement between the two groups of first gears 603 and the two groups of second gears 604, and then release the movable rod 607. Under the rebound of the spring 608, the limiting rod 610 can be reinserted into the second limiting hole 611 and the first limiting hole 609.
