Description

Technical Field

[0001] The present invention relates to a two-in-one cuffed machine, belonging to the technical field of film bag making, sealing and film cutting and sealing packaging. Background Art

[0002] Most of the cuffed machines on the market at present can only complete a single sealing and cutting function, and there are problems such as low production efficiency, large floor area of the equipment, and complex operation. Moreover, the packaging method often relies on manual operation, with low efficiency and potential safety hazards. In recent years, with the rapid development of automation technology, more and more automated packaging equipment has been applied to industrial production. However, there are relatively few fully automated packaging equipment for a specific product, especially in the combined application of cuffed machines and shrink packaging machines, and there is still a large room for innovation. Summary of the Invention

[0003] The present invention overcomes the deficiencies of the prior art and provides a two-in-one cuffed machine, which solves the problem of rapid adjustment of automatic sealing and cutting and automatic shrinking during the packaging process of products, and realizes high-efficiency operation of film packaging.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a two-in-one cuffed machine, including a material pushing platform assembly, an upper / lower film sealing assembly, a cutting knife assembly, a heat shrink furnace cavity assembly, a human-machine interface, a discharging roller assembly and a conveying roller. The conveying roller is horizontally arranged through the heat shrink furnace cavity assembly. An upper / lower film sealing assembly is arranged at the inlet on the side away from the heat shrink furnace cavity assembly of the cutting knife assembly. The material pushing platform assembly is arranged outside the upper / lower film sealing assembly. The discharging roller assembly is arranged at the other end of the conveying roller. The human-machine interface is arranged on the top of the heat shrink furnace cavity assembly; The encapsulated item is placed on the pusher platform assembly. After starting the pusher, the item is pushed forward into the upper / lower film sealing assembly. At this time, as the item is conveyed forward, the upper and lower films in the upper / lower film sealing assembly are pulled together. During the film pulling process, the continuous feeding film signal required for pulling is converted by the upper / lower film pulling signal positions to the upper / lower film sealing assembly for intermittent supply. After the automatic film feeding is completed, the item is conveyed forward by the conveying rollers and then stopped by the system after reaching the cutting knife assembly. Then, the cutting knife assembly performs a horizontal seal. At this time, the first item is sealed in a film bag with both ends open by the film. Then, the second item is conveyed in the above manner and forms the next seal after the item conveying is completed. This item is completely packaged inside the film. And so on, all subsequent items will be packaged with the film. The encapsulated item enters the heat shrink furnace cavity assembly along with the conveying rollers. At this time, the heating tubes in the heat shrink furnace cavity assembly have set the heating parameters through the human-machine interface control panel. The item passes through the furnace cavity, and the attached PE film shrinks and shapes due to high temperature. At the same time, the cooling fan in the heat shrink furnace cavity assembly accelerates its cooling, and then it drives out of the furnace cavity through the roller rods and reaches the discharge roller assembly.

[0005] Further, an inclined pusher plate is provided on the pusher platform assembly. The pusher plate is inclined downward toward the upper / lower film sealing assembly. The pusher plate is slidably arranged on the pusher platform assembly. A control button is provided on one side of the pusher platform assembly. The power component is controlled by the control button to drive the pusher plate to reciprocate on the pusher platform assembly for pushing the item.

[0006] Further, the upper / lower film sealing assembly includes an upper film roller and a lower film roller. The upper film roller and the lower film roller are respectively located at the upper and lower ends of the upper / lower film sealing assembly. Films are respectively wound around the upper film roller and the lower film roller. The films on the upper film roller and the lower film roller respectively extend to the discharge port of the pusher platform assembly through one or more upper film roll auxiliary roller paths and lower film roll auxiliary roller paths. The upper film roll auxiliary roller paths and the lower film roll auxiliary roller paths are horizontally movably arranged on the upper / lower film sealing assembly.

[0007] Further, an adjusting handwheel is provided on one side of the cutting knife assembly. The height of the sealing and cutting knife in the cutting knife assembly is adjusted by driving the adjusting lead screw in linkage through the adjusting handwheel to meet the sealing and cutting requirements of products with different specifications.

[0008] Further, the conveying rollers are driven by a plurality of sprockets and chains.

[0009] Further, the rotational speeds of the upper film roller and the lower film roller are different. During the film pulling process, the continuous feeding film signal required for pulling is converted by the upper / lower film pulling signal positions to the upper film roller or the lower film roller with a slightly faster supply for intermittent supply.

[0010] Furthermore, the structure of the material pushing platform assembly further includes: a limiting plate, a baffle plate, a pushing and pulling plate, a transverse moving plate, a connecting rod assembly, and a driving motor assembly. The transverse moving plate is movably sleeved on the guiding slide rod of the cuff machine frame. The lower side of the transverse moving plate is power-connected to the driving motor assembly through the connecting rod assembly. The driving motor assembly and the connecting rod assembly drive the transverse moving plate to reciprocate on the guiding slide rod. Two pushing and pulling plates are arranged on the upper side of the transverse moving plate. One ends of the two pushing and pulling plates are fixedly arranged on the transverse moving plate. The other ends of the pushing and pulling plates are fixedly connected together through the baffle plate. The baffle plate is vertically arranged. A material pushing plate is arranged at the upper end of the baffle plate. Two limiting plates are arranged in parallel on the front side of the baffle plate.

[0011] Furthermore, after the films of the upper film roller and the lower film roller are stretched and overlapped, they are fused together by the temperature of the cutting knife assembly. After the article presses against the fused film, the film is continuously pressed, so that the film covers the surface of the article and fits behind the article, and then is fused together again by the temperature of the cutting knife assembly and cut off.

[0012] Furthermore, before the films of the upper film roller and the lower film roller converge together, they are both tension-adjusted through multiple transmission rollers, and the number of transmission rollers of the upper film roller and the lower film roller is different.

[0013] The beneficial effects of the present invention compared with the prior art are as follows: By integrating automatic sealing and cutting and automatic shrink packaging into one machine, the present invention reduces the floor area of the equipment and the number of operators, reflects the rapid adjustment requirements of automatic sealing and cutting and automatic shrinking, adopts an advanced automatic control system, realizes one-key operation, and reduces the operation difficulty. By optimizing the work process, the production efficiency is significantly improved, the production cycle is shortened, the original manual intervention-dependent and film packaging methods are adjusted, and new environmentally friendly materials are selected to make the packaging more efficient, firm, beautiful and more energy-saving. At the same time, a plurality of adjusting mechanisms are designed, so that articles of different specifications can be packaged to the best state. As a fully automatic, high-speed, high-efficiency and stable film packaging equipment, the present invention is specifically used for the packaging and shrinking of products to improve production efficiency, reduce production costs; reduce the floor area of the equipment and save production space; reduce the operation difficulty and improve production safety, etc. It can automatically and continuously cut and seal and package products, and the present invention makes up for the problems of most cuff machines in the market that can only complete a single sealing and cutting function, such as low production efficiency, large floor area of the equipment, and complex operation.

Specific Embodiments

[0023] The present invention will be further described below in conjunction with specific embodiments.

[0024] Such as Figures 1 to 7As shown in the figure, the two-in-one cuffs machine of the present invention includes a material pushing platform assembly 1, an upper / lower film sealing assembly 2, a cutting knife assembly 3, a shrink furnace chamber assembly 4, a human-machine interface 5, a discharge roller assembly 6, and a conveying roller 7. The conveying roller 7 is horizontally arranged through the shrink furnace chamber assembly 4. Above one end of the conveying roller 7, there is a cutting knife assembly 3. At the inlet on the side far from the shrink furnace chamber assembly 4 of the cutting knife assembly 3, there is an upper / lower film sealing assembly 2. The upper / lower film sealing assembly 2 includes an upper film roller 21 and a lower film roller 22. The upper film roller 21 and the lower film roller 22 are respectively located at the upper and lower ends of the upper / lower film sealing assembly 2. Films are respectively wound on the upper film roller 21 and the lower film roller 22. The films on the upper film roller 21 and the lower film roller 22 respectively extend to the discharge port of the material pushing platform assembly 1 through one or more upper film roll auxiliary roller paths 23 and lower film roll auxiliary roller paths 24. The upper film roll auxiliary roller paths 23 and the lower film roll auxiliary roller paths 24 are horizontally movably arranged on the upper / lower film sealing assembly 2. The rotational speeds of the upper film roller 21 and the lower film roller 22 are different. During the film pulling process, the continuous feeding film signal required for pulling is converted into an intermittent supply signal for the upper film roller 21 or the lower film roller 22 with a slightly faster supply through the upper / lower film pulling signal positions. The material pushing platform assembly 1 is arranged outside the upper / lower film sealing assembly 2. An inclined material pushing plate 11 is arranged on the material pushing platform assembly 1. The material pushing plate 11 slopes downward towards the upper / lower film sealing assembly 2. The material pushing plate 11 is slidably arranged on the material pushing platform assembly 1. One side of the material pushing platform assembly 1 is provided with control buttons 12. By controlling the control buttons 12, the power component drives the material pushing plate 11 to reciprocate on the material pushing platform assembly 1 for material pushing. The other end of the conveying roller 7 is provided with a discharge roller assembly 6. The conveying roller 7 is driven by a plurality of sprockets and chains. The human-machine interface 5 is arranged on the top of the shrink furnace chamber assembly 4; The encapsulated item is placed on the pusher platform assembly 1. After starting the pusher, the item is pushed forward into the upper / lower film sealing assembly 2. At this time, as the item is conveyed forward, the upper and lower films in the upper / lower film sealing assembly 2 are pulled together. During the film pulling process, the continuous feeding film signal required for pulling is converted by the upper / lower film pulling signal bits and supplied intermittently to the upper / lower film sealing assembly 2. After the automatic film feeding is completed, the item is conveyed forward by the conveying roller 7 and then stopped by the system after passing through the cutting knife assembly 3. Then, the transverse sealing is performed through the cutting knife assembly 3. At this time, the first item is sealed in a film bag with both ends open by the film. Then, the second item is conveyed in the above manner and forms the next seal after the item conveying ends. This item is completely packaged with the film inside. And so on, all subsequent items will be packaged with the film. The encapsulated item enters the heat shrink furnace cavity assembly 4 along with the conveying roller 7. At this time, the heating tubes in the heat shrink furnace cavity assembly 4 have been set with heating parameters through the control panel of the human-machine interface 5. The item passes through the furnace cavity, and the attached PE film shrinks and shapes due to high temperature. At the same time, the heat dissipation fan of the heat shrink furnace cavity assembly 4 accelerates its cooling, and then it reaches the discharge roller assembly 6 through the roller rod after driving out of the furnace cavity.

[0025] The structure of the pusher platform assembly 1 in the present invention further includes: a limit plate 13, a baffle plate 14, a push-pull plate 15, a transverse moving plate 16, a connecting rod assembly 17, and a driving motor assembly 18. The transverse moving plate 16 is movably sleeved on the guiding slide rod 9 of the cuff machine frame 8. The lower side of the transverse moving plate 16 is power-connected to the driving motor assembly 18 through the connecting rod assembly 17. The transverse moving plate 16 is driven to reciprocate on the guiding slide rod 9 by the driving motor assembly 18 and the connecting rod assembly 17. Two push-pull plates 15 are arranged on the upper side of the transverse moving plate 16. One ends of the two push-pull plates 15 are fixedly arranged on the transverse moving plate 16. The other ends of the push-pull plates 15 are fixedly connected together through the baffle plate 14. The baffle plate 14 is vertically arranged. A pusher plate 11 is arranged at the upper end of the baffle plate 14. Two limit plates 13 are arranged in parallel on the front side of the baffle plate 14.

[0026] In the present invention, the films of the upper film roller 21 and the lower film roller 22 are fused together by the temperature of the cutting knife assembly 3 after being stretched and overlapped. After the item presses against the fused film, it continues to press the film, so that the film covers the surface of the item and fits behind the item, and then is fused together again by the temperature of the cutting knife assembly 3 and cut off.

[0027] In the present invention, the films of the upper film roller 21 and the lower film roller 22 are tension-adjusted by multiple transmission rollers before converging together, and the number of transmission rollers of the upper film roller 21 and the lower film roller 22 is different.

[0028] One side of the cutting knife assembly 3 in the present invention is provided with an adjusting handwheel. The sealing and cutting height of the sealing and cutting knife in the cutting knife assembly 3 is adjusted by driving the adjusting lead screw in linkage through the adjusting handwheel to meet the sealing and cutting requirements of products with different specifications.

[0029] The present invention is a sealing and cutting system driven by a servo motor in cooperation with a high-precision reduction gear and then through chain drive, ensuring the high speed and accuracy of the sealing and cutting film operation. In the present invention, the operator places the item to be wrapped in front of the pusher plate and presses the control button beside him / her, and the item is pushed to the film sealing area; it is completed by two sets of identical but independent film feeding mechanisms and film pulling mechanisms, upper and lower. The film pulling mechanism triggers the detection element during the feeding process of the item. The film pulling mechanism obtains the signal to pull the film, and at the same time this signal is sent to the film feeding mechanism to feed the film, and the automatic film feeding process is completed according to the designed logic.

[0030] In the present invention, during the conveying and loading process of the item, the item is packaged in a film bag with openings on both sides through sealing and cutting, and this process is completed synchronously during sealing and cutting.

[0031] In the present invention, the detection element detects that the item is automatically sealed after passing through. In the present invention, while the item passes through the sealing and cutting film, the link rod pushes it into the furnace cavity, and the PE film shrinks and takes shape after being heated to a high temperature. In the present invention, when the item changes, the two-in-one cuffs machine can be adjusted by adjusting the handwheel designed on one side of the machine. The handwheel drives the trapezoidal lead screw to move to drive the up and down movement of the cutter assembly to complete the height adjustment.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of the present invention.
