[0002] In modern industrial production, flexible materials such as non-woven fabrics are increasingly used. After cutting, non-woven fabrics need to be bagged and packaged.

[0003] However, in the actual packaging process, due to the relatively soft texture of flexible materials, after the piles of flexible materials are transported horizontally by the conveyor belt, they are difficult to be stably grabbed and separated from the conveyor belt. This makes the bagging and packaging operation of the piles of flexible materials usually done manually. Manual bagging not only leads to low packaging efficiency, but also easily causes abnormal contact between workers and flexible materials, which easily causes contamination of flexible materials with high cleanliness requirements such as non-woven fabrics during the bagging and packaging process. In addition, due to the soft texture of the flexible materials, during the bagging and packaging process, piles of flexible materials are prone to irregular stacking, looseness and disorder when being put into packaging bags, affecting the quality of the flexible materials after packaging.

[0049] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0050] Example: This example provides an automatic packaging system for flexible materials. Figure 1 - Figure 17 Specifically, it includes a conveying mechanism, which includes a conveying frame 1, and rollers 101 are rotated at the left and right ends of the conveying frame 1, and a number of evenly distributed rollers 102 are fixed on the rollers 101. A conveyor belt 103 is connected with a transmission sleeve between the two corresponding rollers 102 on the left and right. A servo motor 104 for driving the rollers 101 to rotate is fixed on the conveying frame 1. A bag supporting mechanism is arranged at the rear end of the conveying frame 1. The bag supporting mechanism includes a bag supporting platform 2, and a horizontally arranged double-slider electric screw assembly 201 is fixed on the top of the bag supporting platform 2, and a supporting plate 202 is respectively fixed on the two sliders on the double-slider electric screw assembly 201.

[0051] During the operation of the packaging system, the conveying mechanism is started to convey the piles of flexible materials. The piles of flexible materials are placed on the plurality of conveyor belts 103 from the right end of the conveying rack 1, and then the servo motor 104 is powered on and started, driving the roller 101 connected to its drive shaft to rotate, thereby driving the roller 102 to rotate, driving the plurality of conveyor belts 103 to rotate continuously. During the rotation of the plurality of conveyor belts 103, the piles of flexible materials placed on them will be driven to be conveyed from right to left. In the process of the piles of flexible materials being conveyed by the conveying mechanism, the bag-holding structure is started, which will open the packaging bag in advance, and the packaging bag is placed on the bag-holding platform 2. The two symmetrical support plates 202 are moved from the front to the back. The two ends are inserted into the opening of the packaging bag. The double-slider electric screw assembly 201 is composed of a bidirectional screw and two symmetrically arranged sliders. The two sliders are respectively screwed to the two ends of the bidirectional screw. After the double-slider electric screw assembly 201 is powered on and started, the bidirectional screw is driven to rotate under the drive shaft of the motor, driving the left and right sliders to move synchronously relative to each other. When performing the bag-holding operation, the double-slider electric screw assembly 201 is powered on to drive the two support plates 202 inserted in the packaging bag away from each other, and the bag opening of the packaging bag is opened. The support plate 202 is set to a long plate shape. With the support of the left and right support plates 202, the bag opening of the packaging bag is opened to form a rectangular shape suitable for loading piles of flexible materials.

[0052] A lifting mechanism is provided on the left side of the end of the conveying frame 1, and the lifting mechanism includes a first frame 3. A longitudinally arranged lifting platform 301 is installed in the first frame 3 for lifting and lowering, and a plurality of transversely arranged support rods 302 are fixed on the side of the lifting platform 301 close to the conveying frame 1. The support rods 302 are housed on the inner side of the end of the conveying frame 1, and a plurality of evenly distributed first U-shaped grooves 303 are provided on the top of the support rods 302. A vertically arranged first electric push rod 304 is fixed at the bottom of the first frame 3, and the telescopic end of the first electric push rod 304 is fixedly connected to the lifting platform 301.

[0053] In the initial state, the plurality of support rods 302 are stored inside the left end of the conveyor frame 1. When the support rods 302 are stored inside the left end of the conveyor frame 1, the top of the support rods 302 is flush with the top of the conveyor frame 1. In this state, the top of the support rods 302 is below the top of the conveyor belt 103. When the pile of flexible materials is conveyed to the left end of the conveyor frame 1, it will not be blocked and can be smoothly conveyed to the plurality of support rods 302 stored inside the left end of the conveyor frame 1. Then the first electric push rod 304 is powered on and started. The telescopic end drives the lifting platform 301 to move upward along the first frame 3, and the lifting platform 301 drives the plurality of supporting rods 302 to move upward. The plurality of supporting rods 302 are staggered between the plurality of conveyor belts 103, so that the supporting rods 302 will not be blocked by the conveyor belts 103 during the rising process. During the rising process, the plurality of supporting rods 302 will pass through the plurality of conveyor belts 103 and lift the piles of flexible materials from the bottom to the top, thereby realizing the stable separation of the piles of packaging bags from the conveying mechanism.

[0054] The front end of the conveyor frame 1 is provided with an insertion mechanism located in front of the bag support mechanism, and the insertion mechanism includes a second frame 4, a longitudinally arranged single-slider electric screw assembly 401 is fixed on the top of the second frame 4, and a bearing plate 402 is fixed on the slider of the single-slider electric screw assembly 401, and the bottom of the bearing plate 402 is connected to the third frame 403, and a plurality of longitudinally arranged first round rods 404 are installed at the rear of the bottom of the third frame 403, and the plurality of first round rods 404 correspond one to one with the plurality of first U-shaped grooves 303, and the third frame 403 A lifting plate 405 is installed inside the lifting device, and a second round rod 406 located above the first round rod 404 is installed behind the lifting plate 405. A second electric push rod 407 is fixed upright on the top of the supporting plate 402, and the telescopic end of the second electric push rod 407 is fixedly connected to the lifting plate 405. A third electric push rod 5 is fixed longitudinally in the third frame 403, and the third electric push rod 5 is located below the lifting plate 405. A push block 501 located between the first round rod 404 and the second round rod 406 is fixed on the telescopic end of the third electric push rod 5.

[0055] When the packaging system is in operation, after the supporting rods 302 lift the pile of flexible materials to a position with the same height as the bag opening of the packaging bag, the insertion mechanism is started. After the single-slider electric screw assembly 401 is energized, the upper slider drives the supporting plate 402 to move backward, driving the first round rods 404 installed at the rear of the bottom of the third frame 403 to move backward. The first round rods 404 are accurately inserted into the first U-shaped grooves 303 evenly opened on the top of the supporting rods 302. In this state, the first round rods 404 are at the bottom of the pile of flexible materials supported by the supporting rods 302, and then the telescopic end of the first electric push rod 304 retracts and resets, driving the lifting platform 301 to drive the supporting rods 302 to move downward. The supporting rods 302 are re-stored inside the left end of the conveying rack 1, and the pile of flexible materials originally supported on the top of the supporting rods 302 will be transferred to the first round rods 404.

[0056] During the descent of the support rod 302, the second electric push rod 407 is started synchronously, driving the lifting plate 405 to drive the plurality of second round rods 406 to move downward, so that the plurality of second round rods 406 are pressed down on the pile of flexible materials, and finally the flexible materials are clamped between the plurality of first round rods 404 and second round rods 406. Then the single slider electric screw assembly 401 continues to start, driving the pile of flexible materials clamped between the first round rods 404 and second round rods 406 to continue to move backward, and the pile of flexible materials is passed from front to back through the opened bag. The flexible material is put into the packaging bag through the opening, and then the third electric push rod 5 is powered on and started, and its telescopic end drives the push block 501 to move backward, pushing the flexible material clamped between the first round rod 404 and the second round rod 406 to the deep inside of the packaging bag, completing the bagging operation of the pile of flexible materials. After the bagging is completed, the single-slider electric screw assembly 401 drives the carrying plate 402 to move forward, and the third electric push rod 5 drives the push block 501 to retract and reset, so that the insertion and feeding mechanism returns to its initial state. The above operations are repeated to realize the automatic bagging operation of the pile of flexible materials.

[0057] During the operation of the packaging system, by initially storing the plurality of supporting rods 302 inside the end of the conveying frame 1 and manipulating the plurality of supporting rods 302 to move up and down, the pile of flexible materials can be efficiently and conveniently separated from the conveying mechanism and adjusted to a position that is consistent with the height of the bag opening. Then, by moving the plurality of first round rods 404 back and forth and cooperating with the first U-shaped grooves 303 adapted to be provided on the supporting rods 302, the first round rods 404 can be inserted into the bottom of the pile of flexible materials. With the support rods 302 falling and resetting, and the backward conveying of the carrying plate 402, an automatic and efficient bagging operation of the pile of flexible materials can be realized, which can not only effectively improve the bagging efficiency, It can also prevent workers from coming into contact with flexible materials and prevent the flexible materials from being contaminated when being bagged. It is especially suitable for bagging soft fabrics such as non-woven fabrics that require high cleanliness. At the same time, by movably installing the second round rod 406 on the first round rod 404, the first round rod 404 and the second round rod 406 can cooperate to clamp the piles of flexible fabrics, which not only prevents the flexible fabrics from scattering during the bagging process, but also can compress the height of the piles of flexible fabrics by clamping, so that the piles of flexible fabrics can be more conveniently and accurately passed through the bag opening and loaded into the packaging bag. With mutual cooperation, efficient, convenient, and precise and automated packaging processing of flexible fabrics without human contact can be achieved.

[0058] In the specific implementation process, Figure 6 、 Figure 7 and Figure 9 As shown, a vertical baffle 305 is installed on the top of the support rod 302 near the lifting platform 301. A number of evenly distributed threaded holes are opened on the top of the support rod 302 near the lifting platform 301. The baffle 305 is firmly installed on the support rod 302 by screwing bolts and the threaded holes. When the packaging system is in operation, when the conveying mechanism is used to horizontally convey the piled flexible materials, since the baffle 305 is vertically erected on the side of the top of the support rod 302 near the lifting platform 301, the baffle 305 is erected on the side of the top of the support rod 302 away from the conveying frame 1. Through the obstruction of the baffle 305, the piled flexible materials can be blocked and positioned during the conveying process, and the piled flexible materials are conveyed. After reaching the left end of the conveyor rack 1, it will be blocked by the upright baffle 305, which can prevent the flexible material from falling over the end of the conveyor rack 1. The baffle 305 is arranged to be aligned with the open position of the bag opening of the packaging bag, so that the pile of flexible materials can be in the same vertical line as the open bag opening after being blocked by the baffle 305, which is convenient for subsequent operations. The packaging system can more accurately and efficiently load the piles of flexible materials into the packaging bags. The baffle 305 is fixedly connected with the threaded holes on the support rod 302 by bolts. By providing a large number of threaded holes on the support rod 302, the staff can flexibly adjust the position of the baffle 305 according to actual needs, which can effectively improve the flexibility of the packaging system in actual use.

[0059] In the specific implementation process, Figure 3 、 Figure 10 and Figure 13 As shown, the outer surfaces of the first round rod 404 and the second round rod 406 are set to a smooth structure, and the outer diameters of the first round rod 404 and the second round rod 406 gradually decrease from front to back. During the operation of the packaging system, by setting the outer surfaces of the first round rod 404 and the second round rod 406 to a smooth structure, the friction resistance between the first round rod 404, the second round rod 406 and the flexible material can be reduced. In addition, by setting the outer diameters of the first round rod 404 and the second round rod 406 to gradually decrease from front to back, not only can the first round rod 404 and the second round rod 406 clamp the pile of flexible materials into the packaging bag more smoothly, but also can ensure that the push block 501 pushes the pile of flexible materials deep into the packaging bag smoothly. At the same time, the setting of the smooth structure of the outer surfaces of the first round rod 404 and the second round rod 406 can also prevent the flexible material from being scratched and damaged during the clamping process, which is conducive to ensuring the stability of the flexible material when it is bagged.

[0060] In the specific implementation process, Figure 3 、 Figure 7 、 Figure 10 and Figure 13 As shown, the third frame 403 is connected to the bottom of the carrying plate 402 by lifting, and a fourth electric push rod 6 is fixed on the top of the carrying plate 402, and the telescopic end of the fourth electric push rod 6 is fixedly connected to the third frame 403. A second U-shaped groove 601 corresponding to the plurality of first round rods 404 is provided in front of the end of the conveying frame 1. During the operation of the packaging system, another mode of operation can also be performed. After the conveying mechanism conveys the piles of flexible materials to the left end of the conveying frame 1, the piles of flexible materials are blocked by the upright baffle 305, so that the flexible materials are above the plurality of supporting rods 302. At this time, the first electric push rod 304 is not started first, and the supporting rod 302 Keeping it in the state of being stored inside the left end of the conveying frame 1, the fourth electric push rod 6 is powered on and started, driving the third frame 403 to move downward under the supporting plate 402, and the third frame 403 drives the many first round rods 404 to move downward, so that the ends of the many first round rods 404 are placed in the many first U-shaped grooves 303 evenly opened on the frontmost support rod 302, and a touch pressure sensor is provided in the first U-shaped groove 303 here. By pressing the touch pressure sensor in the first U-shaped groove 303 with the end position of the first round rod 404 during the descent of the third frame 403, it can be determined whether the third frame 403 has fallen into place, which can effectively ensure the stability of the device during operation.

[0061] The numerous second U-shaped grooves 601 opened in front of the end position of the conveying frame 1 can provide gaps for the numerous first round rods 404 to be lowered to the same height of the first U-shaped groove 303, thereby ensuring the stability of the first round rods 404 when lowered into place. Then the first electric push rod 304 and the fourth electric push rod 6 are started synchronously, and the first electric push rod 304 drives the lifting platform 301 to drive the numerous supporting rods 302 to move upward, lifting the flexible material upward. Synchronously, the telescopic end of the fourth electric push rod 6 contracts, and the third frame 403 is controlled to drive the numerous first round rods 404 to move upward. The rise of the first round rod 404 is consistent with the rise of the supporting rod 302. During the rising process, the first round rod 404 always remains at the same height as the first U-shaped groove 303.

[0062] During the rising process, the single-slider electric screw assembly 401 will start. When the supporting rod 302 lifts the pile of flexible materials over the top of the conveyor belt 103, the single-slider electric screw assembly 401 drives the carrying plate 402 to move backward, so that the first round rod 404 moves backward synchronously during the rising process and quickly inserts into the corresponding first U-shaped groove 303. Synchronously, after the first round rod 404 is inserted into place, the second electric push rod 407 is powered on and started, controlling the lifting plate 405 to drive the second round rod 406 to move downward, pressing on the top of the pile of flexible materials, limiting the top of the pile of flexible materials, and avoiding the pile of flexible materials. The flexible material scatters during the rapid rise. When the supporting rod 302 and the first round rod 404 rise to a height aligned with the packaging bag, the supporting rod 302 moves downward to reset, and the single-slider electric screw assembly 401 continues to start, driving the first round rod 404 and the second round rod 406 to deliver the clamped pile of flexible materials into the packaging bag to complete the bagging operation. In this operating mode, the pile of flexible materials will be clamped by the first round rod 404 and the second round rod 406 during the rising process, which can prevent the pile of flexible materials from scattering due to rapid rise, which is conducive to ensuring the stability, accuracy and efficiency of the flexible materials being transported and bagged.

[0063] In the specific implementation process, Figure 1 and Figure 13 - Figure 15As shown, the bottom of the third frame 403 and the interior of the lifting plate 405 are both provided with cavities, and the third frame 403 and the lifting plate 405 are fixed with air pipes 7 connected to the cavities. A plurality of evenly distributed first air holes 701 are provided on the lower side of the first round rod 404 and the upper end wall of the second round rod 406, and a second air hole 702 is provided at the end axis position of the first round rod 404 and the second round rod 406. The first air holes 701 and the second air holes 702 on the first round rod 404 and the second round rod 406 are both connected to the corresponding cavities. During the operation of the system, the outer end of the air tube 7 is connected to the air pump. When the first round rod 404 and the second round rod 406 clamp the pile of flexible fabrics and put them into the packaging bag, the air flow enters the cavity through the air tube 7 and then sprays out through the first air hole 701 and the second air hole 702. The air flow can further expand the packaging bag, which is conducive to improving the smoothness of the packaging system when putting the pile of flexible materials into the packaging bag. The openings of the first air hole 701 and the second air hole 702 are set to a smooth structure to avoid scratching the flexible material.

[0064] In the specific implementation process, Figure 10 、 Figure 14 and Figure 15 As shown, the first round rod 404 is rotatably connected to the third frame 403, the second round rod 406 is rotatably connected to the lifting plate 405, a first transmission belt assembly 8 is transmission-connected between two adjacent first round rods 404, a first micro motor 801 for driving the first round rod 404 to rotate is fixed on the third frame 403, a second transmission belt assembly 802 is transmission-connected between two adjacent second round rods 406, and a second micro motor 803 for driving the second round rod 406 to rotate is fixed on the lifting plate 405.

[0065] During the operation of the packaging system, since the first round rod 404 is rotatably connected to the third frame 403, and the second round rod 406 is rotatably connected to the lifting plate 405, the first round rod 404 and the second round rod 406 can be driven to rotate. When the lifting mechanism cooperates with the pumping mechanism to lift and clamp the pile of flexible materials, the first micro motor 801 and the second micro motor 803 are powered on and started. With the help of the transmission connection between the first transmission belt assembly 8 and the second transmission belt assembly 802, the first round rod 404 and the second round rod 406 can be driven to rotate. During this process, the airflow ejected from the first air hole 701 opened on the first round rod 404 will sweep the bottom of the pile of flexible materials, and the airflow ejected from the first air hole 701 opened on the second round rod 406 will sweep the top of the pile of flexible materials. Before bagging, the upper and lower sides of the pile of flexible materials are blown clean in advance.

[0066] During air blowing cleaning, the force of the first round rod 404 and the second round rod 406 in clamping the pile of flexible materials is relatively small, which can reduce the force of the first air hole 701 contacting the flexible material during the rotation and movement. When the first round rod 404 cooperates with the second round rod 406 to clamp the pile of flexible materials and put them into the packaging bag, the first micro motor 801 and the second micro motor 803 stop starting. In this state, the first air hole 701 opened on the first round rod 404 is adjusted downward by rotation, and the first air hole 701 opened on the second round rod 406 is adjusted upward by rotation, ensuring that the air flow can be blown into the packaging bag stably during the bagging process, and the flexible material can be prevented from being scratched by the opening position of the first air hole 701 during the process of being pushed into the packaging bag. In addition, during the bagging process, the force of the first round rod 404 and the second round rod 406 in clamping the pile of flexible materials is increased, so that the thickness of the pile of flexible materials is further compressed, which facilitates the flexible material to be loaded into the packaging bag.

[0067] Specifically, the working principle and operation method of the present invention are as follows:

[0068] The pile of flexible materials is placed on the conveyor belt 103 from the top of the right end of the conveyor frame 1, and the servo motor 104 is powered on and started, driving the roller 101 to drive the roller 102 to rotate, driving the conveyor belt 103 to rotate, and driving the pile of flexible materials to be transported to the left end of the conveyor frame 1. The pile of flexible materials is blocked by the baffle 305 and is placed on many supporting rods 302. During this process, the two support plates 202 are inserted into the bag opening of the packaging bag, and the double-slider electric screw assembly 201 is started, and the upper slider drives the two support plates 202 to move away from each other, opening the bag opening, and then the first electric push rod 304 is powered on and started, driving the lifting platform 301 to drive many supporting rods 302 to lift the pile of flexible materials to a state aligned with the bag opening, and the single-slider electric screw assembly 401 is powered on and started, and the upper slider drives the supporting plate 402 to drive the first round rod 404 to move backward, accurately inserting into the first U-shaped The bottom of the flexible material on the supporting rod 302 is in the groove 303, and then the second electric push rod 407 is energized and started, controlling the lifting plate 405 to drive the second round rod 406 to move downward, and the first round rod 404 and the second round rod 406 cooperate to clamp the pile of flexible materials, and then the first electric push rod 304 contracts, driving the many supporting rods 302 to fall and reset to the inside of the end of the conveyor frame 1, and the single-slider electric screw assembly 401 continues to start, driving the pile of flexible materials clamped in the first round rod 404 and the second round rod 406 into the packaging bag, and then the third electric push rod 5 is energized and started, controlling the push block 501 to move backward, and the flexible material clamped between the first round rod 404 and the second round rod 406 is sent deep into the packaging bag. After the bagging is completed, the bag supporting mechanism, the lifting mechanism and the insertion mechanism are reset to the initial state, ready for the next bagging operation of the pile of flexible materials.

[0069] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
