Description

Technical Field

[0001] The utility model relates to the technical field of stretch film packaging machines, in particular to a vertical full-chain device for a fully automatic stretch film packaging machine. Background Art

[0002] Fully automatic stretch film packaging machines are widely used in industries such as food, pharmaceuticals, and daily necessities. They are primarily used to stretch film products, providing a sealed, protective layer and aesthetically pleasing display. These machines automatically complete the entire packaging process, from film loading, heating and softening, vacuuming, inflation (if necessary), sealing, to finished product delivery. This significantly improves production efficiency and ensures consistent packaging quality.

[0003] The existing stretch film needs to be manually passed from the film feeding roller through the forming studio, then through the film guide roller, and to the heat sealing studio for pressing before it can drive the upper stretch film to move. When the upper and lower films do not fit together, the upper forming studio needs to be adjusted to move up and down. This method is relatively time-consuming and there is a certain risk in film threading. The stretch film is prone to deviation and excessive looseness during high-speed movement, which causes wrinkles in the product and uneven sealing. Utility Model Content

[0004] The purpose of the utility model is to provide a vertical full-chain device for a fully automatic stretch film packaging machine to solve the technical problems raised by the above background technology.

When the upper film roller rotates, the stretch film can be pulled to move, thereby facilitating the fixation of the stretch film on the upper film roller. At this time, the stretch film will be formed and sealed through the molding studio and the heat-sealing studio, thereby facilitating the processing of the stretch film, and adopts a full-chain method to pass through the heat seal, which perfectly solves the problem of difficulty in passing the film. At the same time, the film is formed as it is fed, saving time and cost, and being efficient. By making the stretch film driven by the chain body to seal and vacuum, the product is wrinkle-free and the seal is beautiful. This is the use feature of the vertical full-chain device of the fully automatic stretch film packaging machine. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] See also Figure 1 The utility model provides a full-automatic stretch film packaging machine vertical full-chain device, which includes an operating table 1; a frame 2 is installed on the top of the operating table 1.

[0017] A film entry roller 3 is installed in the middle of the frame 2, and an upper film roller 4 is provided on one side of the film entry roller 3. The two sides of the upper film roller 4 are connected with a chain body 5 through a transmission sprocket. A molding studio 6 is provided at the bottom of the upper film roller 4, and a fixed friction strip 7 is provided on the outside of the chain body 5. The bottom of the chain body 5 is connected with a transmission shaft 8 through a transmission sprocket. A nylon support ring 9 is installed on the outside of the transmission shaft 8. A heat sealing studio 10 is provided on the outside of the chain body 5 parallel to the operating table 1. The chain body 5 passes through one side of the heat sealing studio 10 and is connected to a pressing sprocket 11. An open sprocket 12 is provided on one side of the pressing sprocket 11. A tensioning adjustment sprocket 13 is provided on one side of the frame 2. The fixed friction strip 7 is installed on the side of the frame 2. The heat sealing studio 10 is installed on the top of the operating table 1. The chain body 5 is an L-shaped structure. The pressing sprocket 11 and the open sprocket 12 are both installed on the top of the operating table 1 through a fixed frame. The tensioning adjustment sprocket 13 is provided on the inner side of the chain body 5.

[0018] During specific implementation, the vertical full-chain device of the fully automatic stretch film packaging machine first passes the stretch film through the bottom of the film-entry roller 3 and connects it to the top of the upper film roller 4, and the transmission sprockets on both sides drive the upper film roller 4 to rotate, so that the stretch film can be bitten and driven to move the stretch film. It is only necessary to press the stretch film on the upper film roller 4, so it is convenient and fast to enter the film, and then the chain body 5 drives the stretch film into the forming studio 6. The stretch film can be formed after passing through the forming studio 6, and no waste of stretch film will be generated. At the same time, the chain body 5 passes through the fixed friction strip 7 fixed on the frame 2 and is connected to the transmission sprockets on both sides of the transmission shaft 8. The fixed friction strip 7 can prevent the chain body 5 from shaking. A nylon support ring 9 is installed on the transmission shaft 8, and the nylon support ring 9 is used to make the stretch film move during the forming process. The formed shape is not destroyed during the process, and wrinkles and deformation of the stretch film are avoided. The chain body 5 continues to pass through the integrated friction strip on the operating table 1 and enters the heat sealing studio 10. This friction strip makes the chain body 5 run more stably and smoothly at the heat sealing position. The stretch film is passed from the heat sealing studio 10 to the pressing sprocket 11 and the open sprocket 12. The open sprocket 12 adopts an open form, so as to avoid the chain body 5 from jumping teeth. At the same time, the pressing sprocket 11 is pressed down to ensure the stability of the open sprocket 12. The stretch film is unbuckled here, and the chain continues to pass through the friction strip for circulation. At the same time, the tensioning adjustment sprocket 13 can adjust the tightness of the chain body 5 and can perform slight adjustments to the nests. This method saves labor, saves costs, operates efficiently and stably, and the sealing method is wrinkle-free and beautiful.

[0019] See Figure 1-Figure 3It can be seen that when in use, the stretch film can be passed through the bottom of the film inlet roller 3 and connected to the top of the upper film roller 4. The mold can be quickly penetrated through the cooperation of the transmission sprocket and the upper film roller 4. At the same time, the chain body 5 drives the heat sealing studio 10 to seal, thereby avoiding wrinkles on the seal and wrinkles caused by shape extrusion after molding. The upper and lower films are simply aligned by adjusting the chain body 5 for small deviations. The chain body 5 drives the upper and lower films to fit accurately and run smoothly and stably. The vertical upper film chain saves space, can make full use of the useful space of the equipment, reduce the risk of film penetration, save stretch film, and save costs.

[0020] To sum up, when the present invention is in use, the stretch film can be passed through the film-feeding roller 3 to be connected to the upper film roller 4, and the stretch film is passed through the forming studio 6, the transmission shaft 8 and the heat-sealing studio 10 in sequence through the transmission sprocket and the upper film roller 4, and finally the stretch film is sealed through the heat-sealing studio 10, thereby avoiding wrinkles at the sealing part of the stretch film and facilitating film feeding. This is the usage feature of the vertical full-chain device of the fully automatic stretch film packaging machine.
