A driving assembly 2 is fixedly installed inside the main frame 1.

[0030] The right side of the main frame 1 is set as a raw material placement place 3, the left side of the raw material placement place 3 is set as a cutting machine 4, the left side of the cutting machine 4 is set as a nozzle hot pressing machine 5, the left side of the nozzle hot pressing machine 5 is set as an upper and lower main film alignment machine 6, the left side of the upper and lower main film alignment machine 6 is set as a side film cutting machine 7, the left side of the side film cutting machine 7 is set as a main film conveying roller 8, the left side of the main film conveying roller 8 is set as a self-supporting bottom knife hot pressing bottom 9, the left side of the self-supporting bottom knife hot pressing bottom 9 is set as a top processing machine 10, the left side of the top processing machine 10 is set as a bottom edge inward folding machine 11, the left side of the bottom edge inward folding machine 11 is set as a side disc assembly 12, and the left side of the side disc assembly 12 is set as a material discharge placement table.

[0031] Specifically, the main frame 1 is used as the supporting structure of the entire production line. A driving component 2 is fixedly installed inside the main frame 1. The driving component 2 provides power for various devices on the production line. The raw material placement 3 is used to store raw materials to be processed, such as composite film rolls such as PET / PET / PE. The raw materials are accurately cut by a cutting machine 4 to form film segments of required size and shape. The suction nozzle is hot-pressed on the cut edge film and fixed on the edge film. Then, the upper and lower main film alignment machines 6 are used to ensure that the upper and lower layers of the film are aligned during the processing, providing accurate positions for subsequent compounding and sealing. The excess part of the edge of the film is removed by the edge film cutting machine 7 to make the product more Beautiful and neat, the main film conveying roller 8 is responsible for conveying the film from one end to the other end to ensure the continuity of the entire production process, the self-standing bottom knife 9 embosses the shape of the self-standing structure at the bottom of the film to enable the product to stand on its own, the top processing machine 10 processes the top of the film, such as sealing, punching, etc., to ensure the sealing and ease of use of the product, the bottom edge inward folding machine 11 folds the bottom edge of the film inward to form the bottom structure of the self-supporting bag, the side disc assembly 12 processes the side edges of the self-supporting bag, such as flattening, hot sealing, etc., to enhance the stability and aesthetics of the product, and finally the discharge placement table is used to store the processed self-supporting bags with top suction nozzles, which is convenient for subsequent packaging and transportation.

[0032] Specifically, the drive assembly 2 fixedly installed inside the main frame 1 provides power for various equipment on the production line, realizing the automatic operation of a series of working steps such as automatic cutting of raw materials, hot pressing of suction nozzles, alignment of upper and lower main films, cutting of side films, main film transportation, hot pressing of self-supporting bottom knives, top processing, folding of bottom edges inwards, side disc processing and placement of discharge materials. This highly automated production process not only improves production efficiency, but also reduces labor costs and error rates.

[0033] Specifically, the bottom 9 is hot-pressed by a self-standing bottom knife, the top processing machine 10 processes the top of the film such as sealing and punching, the bottom edge inward folding machine 11 folds the bottom edge of the film inward, and the side disc assembly 12 processes the side of the self-standing bag such as flattening and hot-sealing, so that the finally produced self-standing bag with a top suction nozzle has good sealing, stability and aesthetics. In addition, the edge film cutting machine 7 that removes the excess part of the edge of the film also makes the product more regular and beautiful.

[0034] Specifically, since the entire production process has been automated and standardized, the maintenance and management of the equipment has become simpler and more convenient. Operators can use the monitoring system to understand the operating status of the production line in real time, discover and solve problems in a timely manner, and ensure the stable operation of the production line.

[0035] The driving assembly 2 includes a driving motor 201 fixedly mounted on the outer surface of the main frame 1, three rotating rods 202 are rotatably mounted inside the main frame 1, sprockets 203 are fixedly mounted on both ends of the outer surfaces of the three rotating rods 202, and each of the three sprockets 203 is connected by a chain 204, eccentric wheels 205 are fixedly mounted on both ends of the outer surfaces of the three rotating rods 202, a placing plate 206 is fixedly mounted on the top of the main frame 1, and a connecting rod 207 is fixedly mounted on the outer surface of each eccentric wheel 205 Guide plates 208 are movably installed at both ends of the main frame 1, connecting blocks 209 are fixedly installed at both ends of the tops of the two guide plates 208, a cross plate 210 is fixedly installed between the tops of the four connecting blocks 209, fixing rods 211 are installed at the four inner corners of the cross plate 210, and the outer surfaces of the four fixing rods 211 are adjusted with return springs 212, and a cross beam 213 is fixedly installed between the tops of the four fixing rods 211, and the top of the placement plate 206 is fixedly connected to the bottom of the cross plate 210.

[0036] The self-supporting bottom knife pressing bottom 9, the top processing machine 10 and the bottom edge inward folding machine 11 are all equipped with a driving assembly 2 inside.

[0037] Specifically, in the automated production line, the self-supporting bottom knife pressing bottom 9, the top processing machine 10 and the bottom edge inward folding machine 11 all involve pressing the plastic film, and therefore are uniformly driven by the driving component 2 to achieve synchronous operation of the entire production line and improve production efficiency. This unified driving method simplifies the control logic of the equipment, reduces the coordination time between devices, and makes the production process smoother.

[0038] Specifically, when the driving motor 201 is turned on, the cooperation between the sprocket 203 and the chain 204 can drive the rotating rod 202 to rotate, and the rotation of the rotating rod 202 can drive the eccentric wheel 205 to rotate. The rotation of the eccentric wheel 205 can drive the guide plate 208, the connecting block 209 and the cross beam 213 to move up and down through the connecting rod 207, and the cross beam 213 squeezes the reset spring 212 during the movement, thereby achieving the purpose of up and down reset remote motion.

[0039] In summary, the automatic production line of self-supporting bags with top suction nozzles has a series of automated operations, including raw material placement, cutting, suction nozzle hot pressing, upper and lower main film alignment, side film cutting, main film conveying, self-supporting bottom knife hot pressing, top processing, bottom edge folding inwards, side disc processing and material placement. This highly automated production process has significantly improved production efficiency, reduced manual intervention, reduced error rate, and made production more stable and reliable.

[0040] Moreover, through the clever design of the driving component 2 and the transmission method of the sprocket 203 and the chain 204, the synchronous operation of multiple devices is achieved. This design not only simplifies the control logic of the equipment and reduces the coordination time between devices, but also effectively reduces the energy consumption of the entire production line. In addition, since a unified driving component 2 is used to provide power for key equipment such as the self-supporting bottom knife pressing bottom 9, the top processing machine 10 and the bottom edge inward folding machine 11, the number of motors is further reduced, thereby reducing energy consumption and the company's energy consumption costs.
