Description

Technical Field

[0001] This utility model relates to the technical field of non-woven bag production and processing equipment, specifically a non-woven bag production and packaging machine. Background Technology

[0002] Non-woven bags are environmentally friendly bags made from non-woven fabric materials. They are produced by using processes such as needle punching, thermal bonding, or chemical bonding to randomly organize and solidify polymer fibers such as polypropylene and polyester into a web. They are lightweight, soft, breathable, flexible, non-flammable, and easily decomposed. Compared to traditional plastic bags, non-woven bags are reusable and have a short degradation period in the natural environment after disposal, effectively reducing white pollution. In practical applications, they are widely used in shopping, advertising, and storage. Patterns and text can be added to the bag body through printing, hot stamping, and other processes, combining practicality with promotional functions.

[0003] Non-woven bags require packaging after production. Currently, most small and medium-sized enterprises still use semi-automatic or purely manual packaging methods, requiring workers to manually complete steps such as placing, wrapping, ironing, and cutting the straps. This process presents the following problems:

[0004] High labor intensity: Workers need to bend over and grab straps repeatedly, which can easily lead to fatigue and fluctuations in production efficiency over a long period of time.

[0005] Insufficient precision: It is difficult to ensure consistent tightness when manually wrapping the straps, which can easily lead to problems such as skewing of the bag and misalignment of the straps, affecting the product qualification rate;

[0006] Poor safety: Manually operating hot pressing equipment (such as soldering irons) poses a risk of burns, and the high-temperature environment exacerbates worker discomfort.

[0007] Therefore, we need to propose a non-woven bag production and packaging machine. Utility Model Content

[0053] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0054] Please see Figure 1-11 This utility model provides a technical solution:

[0055] A non-woven bag production and packaging machine, comprising:

[0056] The main body; the tabletop assembly 4 is located on the top of the main body. The tabletop assembly 4 is made of aluminum profiles and aluminum support tubes, which provides convenience for the storage and movement of cloth bags;

[0057] The main body serves as the supporting foundation for the entire packaging machine, bearing the weight of all other mechanisms. The tabletop assembly 4, constructed from aluminum profiles and support tubes, provides a flat and stable working surface, facilitating the placement and movement of non-woven bags. The use of aluminum combines lightweight with high strength, reducing the overall weight of the equipment while maintaining structural strength; it provides a stable operating platform for the non-woven bag packaging process, allowing the bags to smoothly undergo subsequent processes such as pushing, wrapping, and compressing, ensuring the orderly conduct of the packaging work.

[0058] Please see Figure 1 :

[0059] The bag pushing mechanism 5 is set on the table assembly 4. The bag pushing mechanism 5 includes two pushers. The motor drives the synchronous belt 105 and the linkage shaft to rotate. The two pushers are driven by the synchronous belt 105 to move forward along the guide rail. They cooperate with the clamping mechanism 9 (clamping the free end of the strap) and the feeding mechanism 3 (transmitting straps of equal length) to realize the strap wrapping around the cloth bag once.

[0060] The motor drives the synchronous belt 105 and the linkage shaft to rotate. Two pushers are connected to the synchronous belt 105 and move forward along the guide rail under the drive of the synchronous belt 105. During the bag pushing process, the pushers push the non-woven bag to move, cooperating with the clamping mechanism 9 that clamps the free end of the strap and the feeding mechanism 3 that transmits straps of equal length, so that the strap can complete a full circle around the bag; replacing the manual operation of pushing the bag, realizing automated bag pushing, ensuring the accurate displacement of the bag in the packaging process, laying the foundation for the subsequent strap wrapping process, and improving packaging efficiency and consistency.

[0061] Please see Figure 3 :

[0062] The feeding mechanism 1 is installed at one end of the table assembly 4. The feeding mechanism 1 includes a feeding pressure plate and several sets of guide rollers 109. The strapping is stored in the feeding pressure plate 103 and is transferred to the feeding mechanism 3 through a series of guide rollers 109. The feeding mechanism 1 also includes a feeding shaft 101, a nut 102, a feeding pressure plate 103, a stepper motor 104, a synchronous belt 105, a proximity switch 106, a swing arm 107, and a sensor 108. A support plate is provided at one end of the machine body. The feeding pressure plate 103 is rotatably mounted on the support plate. A feeding rod is provided at the upper end of the support plate. Multiple sets of guide rollers 109 are rotatably mounted on the feeding rod for feeding. A swing arm 107 is installed on one side of the rod, and a proximity switch 106 is installed on the swing arm 107. The feeding shaft 101 is located at the center of the feeding platen. The sensor 108 and the stepper motor 104 are both installed on the support plate. The stepper motor 104 provides power to the feeding platen 103 through the synchronous belt 105. When the swing arm 107 moves away from the proximity switch 106, the stepper motor 104 drives the synchronous belt 105 to rotate the feeding platen and feed material. The sensor 108 is used to detect the presence or absence of strapping. When there is no strapping in the feeding platen 103 or the strapping is accidentally broken, the sensor 108 will send a signal to the PLC to stop feeding.

[0063] The strapping is stored in the feeding platen and transferred through a series of guide rollers 109, eventually being conveyed to the feeding mechanism 3. When the swing arm 107 moves away from the proximity switch 106, the stepper motor 104 drives the feeding platen 103 to rotate via the synchronous belt 105, thus achieving feeding. The sensor 108 monitors the status of the strapping in the feeding platen in real time. When the strapping is used up or breaks unexpectedly, the sensor 108 sends a signal to the PLC to control the equipment to stop feeding. This achieves automatic supply and intelligent monitoring of the strapping, avoiding equipment idling or packaging interruptions caused by untimely manual feeding or undetected strapping breakage, ensuring the continuity and stability of the packaging process, and reducing material waste.

[0064] Please see Figure 4 :

[0065] The pre-compression mechanism 2 is located at one end of the table assembly 4 and below the feeding mechanism 1. The pre-compression mechanism 2 includes a left pressure plate 204, a right pressure plate 201, and a pre-compression cylinder 205. Both the left and right pressure plates are driven by the pre-compression cylinder 205 to compress the cloth bag. The pre-compression mechanism 2 also includes a linear bearing 202, a guide rod 203, and a connecting plate 206. The pre-compression mechanism 2 is linked with the ironing mechanism 6 through the connecting plate 206. The linear bearing 202 and the guide rod 203 work together to ensure that when the left and right ironing heads 608 of the ironing mechanism 6 are moved laterally, the left and right pressure plates 201 of the pre-compression mechanism 2 will also move laterally.

[0066] The pre-compression cylinder 205 drives the left pressure plate 204 and the right pressure plate 201 to compress the non-woven bag placed on the table assembly 4. The pre-compression mechanism 2 is linked with the hot pressing mechanism 6 through the connecting plate 206. With the cooperation of the linear bearing 202 and the guide shaft 812, when the left and right hot pressing heads 608 of the hot pressing mechanism 6 are moved laterally, the left and right pressure plates 201 of the pre-compression mechanism 2 will also move laterally synchronously to ensure the correspondence between the pre-compression and hot pressing positions. The pre-compression of the non-woven bag before the strapping is wrapped reduces the volume of the bag, makes the strapping more compact, and improves the packaging quality. The linkage design with the hot pressing mechanism 6 ensures precise coordination between the pre-compression and hot pressing processes and improves the overall packaging efficiency.

[0067] Please see Figure 5 :

[0068] Feeding mechanism 3 is located at one end of table assembly 4. Feeding mechanism 3 includes a servo motor 302, a driving roller 308, and a driven roller 306. The motor drives the driving roller 308 to rotate, and the driving roller 308 and driven roller 306 press together to feed material. The feeding length is controlled by controlling the number of rotations of the rollers. Feeding mechanism 3 also includes two sets of feeding plates, a handle 301, and a compression spring 305. The driving roller 308 and driven roller 306 are rotatably mounted between the two sets of feeding plates. The servo motor 302 is mounted on the outer wall of one set of feeding plates to drive the driving roller. Wheel 308; a groove is opened on the inner wall of the feeding plate, and a slider 307 is slidably installed in the groove. The shaft of the driven rubber wheel 306 is rotatably connected to the slider 307. A compression spring 305 is installed in one of the grooves. The end of the compression spring 305 is provided with a pressure cap 304 and abuts against the slider 307 of one end of the shaft of the driven rubber wheel 306. A handle 301 is provided on the outside of the slider 307 of the other end of the shaft of the driven rubber wheel 306. A rubber sleeve 303 is fitted on the handle 301. Pulling the handle 301 can separate the driving rubber wheel 308 and the driven rubber wheel 306, which facilitates material feeding.

[0069] The bracket 809 also includes a guide plate 309 for guidance.

[0070] Servo motor 302 drives the active rubber wheel 308 to rotate, and the active rubber wheel 308 presses against the driven rubber wheel 306. By controlling the number of rotations of the rubber wheels, the feeding length is precisely controlled, and the strapping of equal length is conveyed to the designated position. The slider 307 at one end of the shaft of the driven rubber wheel 306 slides in engagement with the groove on the inner wall of the feeding plate. The compression spring 305 pushes the pressure cover 304 to abut against the slider 307, keeping the two rubber wheels in a pressed state. Pulling the handle 301 can separate the driven rubber wheel 306 from the active rubber wheel 308, facilitating the material feeding operation. This achieves precise strapping delivery, controlling the strapping length error within a very small range, ensuring that the strapping length is consistent each time it is wrapped, and solving the problem of inaccurate length feeding by manual feeding. The detachable rubber wheel design facilitates quick strapping replacement and improves the ease of operation of the equipment.

[0071] Please see Figure 6-7 :

[0072] The bandage mechanism 8 is located at one end of the table assembly 4. The bandage mechanism 8 includes a bracket 809, a positioning element 810, a support shaft 811, and a guide shaft 812. The positioning element 810, the support shaft 811, and the guide shaft 812 are all located inside the bracket 809. The hot pressing cylinder 601 drives the bandage mechanism 8 to move downward, discharging excess strapping from the cloth bag and tightening the strapping. The strapping is wound in an S-shape between the support shaft 811 and the guide shaft 812. The strapping is transferred from the bandage mechanism 8 to the clamping mechanism 9.

[0073] It can guide and tighten the straps, ensuring that the straps maintain appropriate tension during the wrapping process, so that the straps fit tightly against the non-woven bag and avoid problems such as looseness or misalignment, thus providing good conditions for subsequent ironing and cutting processes.

[0074] Please see Figure 6-7 :

[0075] The hot pressing mechanism 6 is located at one end of the tabletop assembly 4. The hot pressing mechanism 6 includes a hot pressing cylinder 601 and two sets of hot pressing heads 608. The hot pressing cylinder 601 drives the hot pressing heads 608 to perform hot pressing operations. The hot pressing mechanism 6 also includes a handwheel 602, a screw 603, a sprocket 605 and an ultrasonic mold head 609. The hot pressing cylinder 601 drives the hot pressing heads 608 on both sides to press against the ultrasonic mold head 609, thereby hot pressing the free end of the strap. The handwheel 602 is located at the end of the screw 603 and is connected to the sprocket 605 through a chain to realize the synchronous movement of the hot pressing heads 608 and the mold head.

[0076] The heat-pressing cylinder 601 drives two sets of heat-pressing heads 608 to perform heat-pressing operations, while simultaneously driving the strapping mechanism 8 to move downwards to tighten the strap. The heat-pressing cylinder 601 can also drive the heat-pressing heads 608 on both sides to press against the ultrasonic mold head 609, heat-pressing the free end of the strap through ultrasonic welding. Rotating the handwheel 602 drives the screw 603, which is connected to the sprocket 605 via a chain, to achieve synchronous movement of the heat-pressing heads 608 and the mold head, adapting to the heat-pressing requirements of straps of different widths.

[0077] It can replace manual hot pressing operations, realize automated strapping hot pressing, ensure stable and firm hot pressing quality, and avoid the risk of burns and poor hot pressing caused by manual operation; the adjustable hot pressing head 608 and die head enable the equipment to be adapted to various specifications of strapping, improving the equipment's versatility.

[0078] Please see Figure 9 :

[0079] The strapping clamping mechanism 9 is arranged at one end of the table assembly 4. The strapping clamping mechanism 9 includes a sliding table cylinder 904, a rubber pad 902 and a material pressing plate 903. The sliding table cylinder 904 drives the rubber pad 902 and the material pressing plate 903 to clamp the free end of the strapping band. The strapping clamping mechanism 9 further includes a transverse cylinder 905 and a longitudinal cylinder 906, which are located on both sides of the sliding table cylinder 904 and arranged perpendicularly to each other. Before the ironing operation, the strapping clamping mechanism 9 clamps the strapping band and keeps it stationary, and the pusher mechanism pushes the cloth bag through the strapping clamping mechanism 9 and the feeding mechanism 3, so that the strapping band wraps around the cloth bag for one full turn. When the ironing mechanism 6 is in operation, the sliding table cylinder 904 retracts, the transverse cylinder 905 drives the material pressing plate 903 to move right, the longitudinal cylinder 906 drives the material pressing plate 903 to move backward (away from the die head), and then moves left to re-clamp the material, with the movement trajectory being in a shape of a closed square. After the cutting mechanism 7 cuts off the strapping band, the pre-pressing mechanism 2, the strapping band winding mechanism 8, the ironing mechanism 6 and the cutting mechanism 7 rise, and the longitudinal cylinder 906 drives the material clamping assembly to move forward (close to the die head) to return to the original position, getting ready for the next operation.

[0080] It can accurately clamp and control the free end of the strapping band, ensuring accurate position of the strapping band during the wrapping, ironing and cutting processes. The automatic material clamping and moving operations are realized through the coordinated action of multiple cylinders, which closely cooperates with other mechanisms to ensure the smooth progress of the packaging process.

[0081] See Figure 8 :

[0082] The cutting mechanism 7 is arranged at one end of the table assembly 4. The cutting mechanism 7 includes a driving cylinder 701, a fixing plate 702 and a cutting knife 703. The end of the telescopic rod of the driving cylinder 701 is provided with the fixing plate 702, the cutting knife 703 is mounted at the end of the fixing plate 702, and the driving cylinder 701 moves synchronously with the spot ironing head 608. The driving cylinder 701 of the cutting knife 703 mechanism keeps extending and moves downward together with the spot ironing head 608. After the strapping clamping mechanism 9 re-clamps the strapping band, the cutting knife 703 on the cylinder retracts to cut off the strapping band, the strapping clamping mechanism 9 returns to its position, and the cutting mechanism 7 rises and extends along with the ironing mechanism 6, waiting for the next working cycle.

[0083] It automatically completes the cutting operation of the strapping band, and acts in coordination with the ironing mechanism 6 and the like, so as to ensure that the excess strapping band is cut off timely and accurately after the strapping band is firmly ironed, making the appearance of the packaged non-woven fabric bag neat, while improving the packaging efficiency and reducing the errors and safety hazards of manual cutting.
