Technical Field

[0001] The utility model relates to a double-feeding roll film edge melting machine, belonging to the field of bag making equipment. Background Art

[0002] Packaging bags are bags used to package items, typically made of materials such as plastic, paper, and cloth. They can be categorized into food, cosmetics, pharmaceuticals, and clothing, and are widely used in various fields. Plastic packaging bags are typically made by folding a plastic film in half and then heat-sealing one side of the bag. Therefore, an edge-melting machine is required to melt the edges of the bags. For garment and home textile packaging bags, the front and back are made of two different materials for aesthetic appeal. Therefore, a dual-roll film edge-melting machine is urgently needed to address the problem of fusing the edges of these two films after folding them together. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a double-feed film roll edge melting machine in response to the above-mentioned existing technology, which can simultaneously feed two films of different materials, and then fuse the edges of the two films of different materials after being aligned up and down to form a roll film, thereby improving the film rolling efficiency and being suitable for the front-end processing of bag making of clothing bags and home textile packaging bags.

[0004] The technical solution adopted by the present invention to solve the above-mentioned problem is as follows: a double-feed film roll edge melting machine, comprising a frame, on which a double-feed mechanism, an edge melting mechanism and a winding drum are sequentially arranged; the double-feed mechanism feeds out two films of different materials; the edge melting mechanism melts the edges of the two films after being joined to form a roll film and two waste edges: an upper waste edge and a lower waste edge; and then the winding drum winds up the roll film; the two waste edges are classified and collected in a waste edge blowing unit;

[0005] The double unwinding mechanism includes a first unwinding drum and a second unwinding drum arranged symmetrically, the upper film is wound around the first unwinding drum, and the lower film is wound around the second unwinding drum; a first roller group and a second roller group are provided on the frame; a first unwinding servo motor drives the first unwinding drum to unwind the upper film and then sends it to the conveying roller group through the first roller group, and a second unwinding servo motor drives the second unwinding drum to unwind the lower film and then sends it to the conveying roller group through the second roller group, so that the upper film and the lower film are aligned on the conveying roller group.

[0006] The waste edge blowing unit includes an upper waste edge blowing component and a lower waste edge blowing component. The upper waste edge blowing component is used to collect upper waste edges, and the lower waste edge blowing component is used to collect lower waste edges.

[0007] The lower waste edge blowing assembly includes a lower fan and a lower waste pipe, and the upper waste edge blowing assembly includes an upper fan and an upper waste pipe.

[0008] The edge melting mechanism comprises two edge melting machines, which are arranged at intervals along the moving direction of the film.

[0009] A main traction servo motor is provided on the inlet side of the edge melting mechanism, and a slave traction servo motor is provided on the outlet side of the edge melting mechanism.

[0010] Compared with existing technologies, the advantages of this utility model lie in: a dual-feed film roll edge melting machine utilizes dual feed mechanisms to simultaneously feed two films of different materials. The edge melting mechanism fuses the edges of the two films to form a roll film, which is then reeled onto a reel. The two waste edges are collected in the corresponding waste edge blowing components, allowing for separate collection and recycling of waste materials. This application is convenient to operate and improves the efficiency of film roll production from two different film materials. It is suitable for the pre-production film roll process in garment and home textile packaging bag making. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0013] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0014] like Figure 1 As shown, a double-feed roll film edge-melting machine in this embodiment includes a frame 12, on which are sequentially mounted a double-feed mechanism, an edge-melting mechanism, and a reel 11. The double-feed mechanism comprises a symmetrically arranged first and second feed mechanisms, with the first feed mechanism feeding an upper film and the second feed mechanism feeding a lower film. The upper and lower films are made of different materials. A conveyor roller assembly is provided on the frame 12, and a main traction servo motor 5 is provided on the inlet side of the edge-melting mechanism 6. The main traction servo motor 5 drives the aligned upper and lower films to be transported via the conveyor roller assembly to the edge-melting mechanism 6 for edge-melting, forming a roll film and two waste edges. The roll film is then wound onto the reel 11, with the two waste edges being the upper and lower waste edges. A traction servo motor 7 is provided on the outlet side of the edge melting mechanism 6, and a waste edge blowing unit is also provided between the edge melting mechanism 6 and the winding drum 11. The waste edge blowing unit includes an upper waste edge blowing component and a lower waste edge blowing component. The traction servo motor 7 drives the upper waste edge and the lower waste edge to be pulled to the upper waste edge blowing component and the lower waste edge blowing component, so that the upper waste edge is collected in the upper waste edge blowing component and the lower waste edge is collected in the lower waste edge blowing component, thereby realizing the classified collection of waste edges of two different materials.

[0015] The first unwinding mechanism includes a first unwinding drum 1, around which the upper film is wound; the second unwinding mechanism includes a second unwinding drum 2, around which the lower film is wound. A symmetrically arranged first roller set 3 and second roller set 4 are mounted on the frame 12. A first unwinding servo motor drives the first unwinding drum 1 to unwind the upper film, which is then conveyed to the conveyor roller set via the first roller set 3. A second unwinding servo motor drives the second unwinding drum 2 to unwind the lower film, which is then conveyed to the conveyor roller set via the second roller set 4. Independent servo motors control the first and second unwinding drums to prevent uneven tension on the upper and lower films, which can lead to loose weld edges or wrinkles.

[0016] The edge melting mechanism comprises two edge melting machines, which are arranged at intervals along the moving direction of the films and perform secondary edge melting on the upper and lower films after they are joined.

[0017] The lower waste edge blowing assembly includes a lower fan 9 and a lower waste pipe 8 , and the upper waste edge blowing assembly includes an upper fan 13 and an upper waste pipe 10 .

[0018] This application utilizes a dual unwinding mechanism to simultaneously unwind two films of different materials. The edge-melting mechanism then fuses the edges of the two films, forming a roll of film that is then reeled onto a reel. The two waste edges are collected in their respective waste edge blowing components, enabling separate collection and recycling of waste materials. This application is convenient to operate and improves the efficiency of rolling films from two different film materials. It is suitable for pre-production film production in garment and home textile packaging bag manufacturing.

[0019] In addition to the above embodiments, the present invention also includes other implementation methods. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the scope of protection of the claims of the present invention.
