[0034] The embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0035] Depend on Figure 1 Combination Figure 2-9 As shown, a tubular film forming structure and an integrated tubular film packaging machine include a frame 1 and a tubular film forming structure; the tubular film forming structure includes:

[0036] The film material feeding device 2 includes a feeding frame 21, a feeding roller shaft 22, and a feeding shaft assembly 23; the feeding roller shaft 22 and the feeding shaft assembly 23 are arranged vertically on the feeding frame 21.

[0037] Traction device 3 is used for film material traction;

[0038] The feeding roller shaft 22, the conveying shaft assembly 23, the traction device 3, and the sealing and cutting device 5 are arranged vertically on the outer side of the side wall of the frame 1. Specifically, the film feeding device 2 is located on the outer surface of the side wall of the frame 1; the feeding roller shaft 22 and the conveying shaft assembly 23 are arranged vertically on the side of the frame 1; in fact, the traction device 3, the sealing and cutting device 5 (in most areas), etc., can all be arranged vertically on the side of the frame. The beneficial effects of this utility model are that by vertically arranging the feeding roller shaft and the conveying shaft assembly in the film feeding device, the product layout is reasonable, the overall product volume is small, the floor space is reduced, the structure and production steps are simplified, and the product operation is convenient and reliable. This utility model can be adapted to different screening machines or weighing machines, making the product adaptable to a wide range. This utility model also has the advantages of simple structure, convenient assembly, reliable operation, small size, and long service life. In fact, existing machinery and equipment can be used inside the frame. In this utility model, a common material sorting and screening device can be set inside the frame, or an optical vision screening device can be set. It can also be used in conjunction with some weighing devices and counting devices to screen out the parts that need to be packaged, including but not limited to screening machines, assembly machines, counting machines, etc. This part can be implemented using existing technology, which will not be elaborated here. This utility model can be mounted on other equipment and will not affect other machinery and equipment.

[0039] The feeding rack 21 is vertically arranged, and there are at least multiple sets of feeding shaft assemblies 23. Each set of feeding shaft assemblies 23 includes at least two feeding roller shafts 231. The different feeding shaft assemblies 23 are arranged vertically. The film material fed from the feeding roller shaft 22 passes around different feeding roller shafts 231 and is connected to the traction device 3 and pulled by the traction device 3. Specifically, the feeding roller shaft 22, feeding shaft assembly 23, traction device 3, and sealing and cutting device 5 are arranged vertically and located on the outer side of the side wall of the frame 1. This structure makes reasonable use of the side space of the frame, the overall layout of the product is reasonable, and the footprint is small.

[0040] This utility model also includes:

[0041] The material guiding mechanism 4 is located on the side wall of the frame 1 and is used for feeding the materials to be packaged.

[0042] A sealing and cutting device 5 is mounted on the frame 1. The sealing and cutting device 5 includes a sealing and cutting frame 51, a heat-sealing mechanism 6, and a film-cutting mechanism 7. The heat-sealing mechanism 6 has a first position during installation, a second position for heat-sealing the bottom of the previous film material, and a third position for heat-sealing the top of the cut film material. The film-cutting mechanism 7 has a first position during installation and a second position for cutting the film material. When the heat-sealing mechanism 6 is in the second position, the film-cutting mechanism 7 is in its second position. The beneficial effects of this invention are that by placing the film material feeding device on the outer surface of the frame side wall, the product layout is reasonable, the overall product volume is small, and the floor space is reduced. The sealing and cutting device integrates cutting and heat sealing, simplifying the structure and production steps, and making the product operation convenient and reliable. This invention also has the advantages of simple structure, convenient assembly, reliable operation, small size, and long service life. Specifically, the film material feeding device of this utility model is located on the outer surface of the side wall of the frame, forming an integrated structure. The film material feeding device is arranged vertically, which occupies little space. The film material feeding and forming is located outside the frame, which facilitates the replacement of film material and material feeding. The structure is simple and occupies little space.

[0043] Further explanation is provided with reference to the accompanying drawings. Taking the initial insertion of the film material as an example, after passing through the traction device, the film material is hooked onto the sealing and cutting device or the clamping device. During machine operation or trial run, the traction device can slightly release the material, or the material can be directly moved from the first heat-sealing assembly to the second heat-sealing assembly for heat sealing. Simultaneously, the film-cutting mechanism removes waste material. Specifically, a power component such as a motor, cylinder, or hydraulic cylinder drives the first transmission shaft to rotate. The first transmission shaft is connected to the connecting plate and drives the connecting plate to rotate. The connecting plate drives the first heat-sealing frame to move linearly via a first crank arm. After the first crank arm reaches its position, the first heat-sealing drive component drives the first heat-sealing frame to continue moving towards the second heat-sealing frame, and heat-seales the bottom of the "first packaging bag" through the heat-sealing component. At the same time, the film-cutting mechanism removes the film material below the heat-sealed area of ​​the "first packaging bag". Typically, the first heat-sealing frame is equipped with a heat-sealing component. However, the heat-sealing component can also be located on the second heat-sealing frame or simultaneously on both. After the bottom of the "first packaging bag" is heat-sealed, the traction device releases material, and film is released according to actual production needs. The clamping device clamps the first packaging bag. At this time, the first crank arm moves, the first heat-sealing drive component, the heat-sealing component, and the film-cutting mechanism repeat the above actions, thus achieving heat sealing of the bottom of the "second packaging bag" through the heat-sealing component. Simultaneously, the film-cutting mechanism cuts off the film material below the heat-sealed area of ​​the "second packaging bag," separating the "first packaging bag" from the "second packaging bag." The clamping device moves the "first packaging bag" to the area between the first and second heat-sealing components, usually by first lowering the first packaging bag, then moving it horizontally to the middle area, and finally lifting it to a certain height. At this point, the first and second heat-sealing components move towards the central area. The suction bag assembly separates the film at the top of the first packaging bag, and the bag opening assembly inserts into the inner wall of the first packaging bag to prevent the top of the bag from closing. The second hopper, driven by the hopper drive, moves downward and inserts into the first packaging bag. At this time, the guide component guides the material to be packaged in the frame into the first hopper and then into the first packaging bag through the second hopper. After the bag is filled, the second hopper and the bag opening assembly return to their positions. The heat-sealing component then heat-seals the top of the first packaging bag, and the punching drive punches vent holes in the packaging bag, thus completing the processing of one packaging bag.

[0044] The heat-sealing mechanism 6 includes a first heat-sealing assembly 61 and a second heat-sealing assembly 62. The first heat-sealing assembly 61 includes a first heat-sealing frame 611, a first crank arm 612, and a first drive shaft 613. The second heat-sealing assembly 62 includes a second heat-sealing frame 621, a second crank arm 622, and a second drive shaft 623. The first drive shaft 613 drives the first heat-sealing frame 611 to move relative to the second heat-sealing frame 621 via the first crank arm 612; the second drive shaft drives the second heat-sealing frame 621 to move relative to the first heat-sealing frame 611 via the second crank arm 622. This structure makes the first and second heat-sealing frames simple in structure and reliable in movement, facilitating reliable heat sealing and cutting.

[0045] This invention also includes a first heat-sealing drive member 63, connected to the first heat-sealing frame 611 and used to drive the first heat-sealing drive member 63 to move linearly. When the heat-sealing mechanism is in the second position, the first heat-sealing frame 611 is driven linearly by the first crank arm 612 and driven by the first heat-sealing drive member 63 to press against the second heat-sealing frame 621. This structure facilitates reliable film feeding and prevents film displacement. Typically, the second heat-sealing frame is equipped with a guide plate, and the film falls against the guide plate. The first heat-sealing drive member facilitates driving the first heat-sealing frame closer to the second heat-sealing frame, facilitating heat sealing of the film by the heat-sealing component.

[0046] This utility model also includes a perforation drive component 64, disposed on the first heat-sealing assembly 61 or the second heat-sealing assembly 62, used to process vent holes in the packaging bag when the heat-sealing mechanism 6 is in the third position; the first heat-sealing frame 611 and the second heat-sealing frame 621 are driven to move relative to each other by the first crank arm 612 and the second crank arm 622 respectively when the heat-sealing mechanism 6 is in the second position. The perforation drive component can perforate the film material to facilitate venting.

[0047] The film-cutting mechanism 7 is mounted on the first heat-sealing assembly 61 and / or the second heat-sealing assembly 62, and is used to cut the film material when the heat-sealing mechanism 6 is in the second position. The film-cutting mechanism 7 includes a cutter 71 and a cutter drive 72. The first heat-sealing frame 611 and / or the second heat-sealing frame 621 are provided with a cutter groove 65. The cutter 71 has a first position located within the cutter groove 65 and a second position extending out of the cutter groove 65 for cutting the film material. This structure achieves simultaneous heat sealing and cutting, improves work efficiency, and reduces production costs.

[0048] This utility model also includes:

[0049] The clamping device 8, located on the frame 1, is used to clamp the cut film material when the film cutting mechanism 7 is in its second position and to drive the cut film material to move vertically and / or horizontally.

[0050] The suction bag assembly 66 is disposed on the first heat sealing assembly 61 and the second heat sealing assembly 62, and is used to suck open the top of the cut film material to facilitate feeding by the material guiding mechanism 4;

[0051] The bag opening component 67 is disposed on the first heat sealing component 61 and the second heat sealing component 62, and is used to insert into the film material that is sucked open by the bag suction component 66 and to adhere to the inner wall of the film material.

[0052] Specifically, the clamping device includes a clamping element, a clamping drive element, and a clamping motion assembly. The clamping drive element is connected to the clamping element and is used to drive the clamping element to clamp or release. The clamping motion assembly is connected to the clamping element and drives the clamping element to move vertically and / or horizontally. The suction bag assembly uses a cylinder to drive the suction nozzle to open the bag, thus opening the top of the packaging bag for easy feeding. The bag opening assembly can keep the packaging bag in the open state, preventing the suction bag assembly from failing and also reducing the energy consumption of the suction bag assembly.

[0053] The material guiding mechanism 4 includes a first hopper 41 and a second hopper 42. The first hopper 41 is located on the side wall of the frame 1 and is used to receive the material to be packaged inside the frame 1. The second hopper 42 is located on the first hopper 41 and can move vertically relative to the first hopper 41. Specifically, it also includes a guide component 43, located on the frame 1, for guiding the material to be packaged to the first hopper 41. The first hopper 41 is equipped with a hopper drive component 44, which is connected to the second hopper 42 and is used to drive the second hopper 42 to move vertically relative to the first hopper 41. This structure facilitates reliable material discharge and prevents the material to be packaged from falling outside the packaging bag.
