Description

Technical Field

[0001] This utility model relates to the field of disposable lunch box production technology, specifically disposable lunch box production and packaging equipment. Background Technology

[0002] Disposable food containers are widely used in the catering industry as a common item for food packaging and takeout delivery. Currently, the most common packaging method for disposable food containers is manual. Workers first manually pull out the plastic film, unfold it, and place it over the food container. Then, a separate heat-sealing device is used to seal and cut the container, and finally, the film opening is manually tied. Although this process is simple in structure, it has many shortcomings in actual production.

[0003] First, the pulling and unfolding of the plastic film is done manually. Operators need to use both hands to pull the film and place the food container. This is not only cumbersome but also prone to errors, affecting the sealing effect and appearance quality, and impacting packaging efficiency.

[0004] Secondly, the sealing and cutting process is often separated from the film opening and cover-up process. The lunch box needs to be moved to another work station for heat sealing and cutting, which can easily cause dust and other contaminants to fall into it.

[0005] Finally, after the lunchboxes are sealed and cut, they still need to be moved manually so that the open side faces the position that is easy to tie, which not only increases the labor intensity but also reduces the overall work efficiency.

[0006] Therefore, there is an urgent need for disposable lunch box production and packaging equipment to meet the demand for large-scale production of disposable lunch boxes. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-6This utility model provides an embodiment of a disposable lunch box production and packaging equipment, including a support 4. A PLC controller 17 is installed on the right side of the support 4. A film roller 1 is installed at the top of the support 4, and a plastic film 3 is sleeved on the outside of the film roller 1. A drive motor 2 is fixedly connected to the middle of the top of the support 4. The drive motor 2 is model MHMD042G1U and is used to drive the film roller 1 to rotate. It has encoder feedback and can maintain a stable speed even during frequent start-stop to prevent stretching of the film material. Cylinder seats 5 are fixedly installed on the upper part of both sides of the inner wall of the support 4. A movable cylinder 6 is fixedly installed on the cylinder seat 5. The movable cylinder 6 is model SMC MGPM16-25Z and has good anti-eccentric load capacity. A connecting frame 7 is fixedly connected to the piston end of the movable cylinder 6. Two sets of vacuum suction cups 8 are fixedly installed on the connecting frame 7. The vacuum suction cups 8 are model SMC. ZP2-T20USJ is made of wear-resistant polyurethane material, with stable adsorption force and is not easily damaged by plastic film 3. Two sets of vacuum suction cups 8 are located on the same vertical plane. Lifting seats 10 are movably installed in the middle of both sides of the inner wall of the bracket 4. A steering motor 11 is installed in the lifting seat 10. The output end of the steering motor 11 is fixedly sleeved with a film-pulling plate 9. The steering motor 11 is model AZM24AK-K, which can precisely control the flipping angle of the film-pulling plate 9 to ensure that the inner clamping position of the plastic film 3 is consistent. The top of the film-pulling plate 9 extends between the two sets of vacuum suction cups 8. The vacuum suction cups 8 are staggered in the horizontal direction. The two sets of moving cylinders 6 have an asymmetrical structure. The width of the film-pulling plate 9 is smaller than the diameter of the film roller 1, and the film-pulling plate 9 is symmetrical about the axis of the film roller 1. Hydraulic rods 16 are fixedly installed inside the bracket 4. The top of the hydraulic rods 16 is fixedly connected to the lifting seat 10. The hydraulic rods 16 are model HC-DYJ32-50, which ensures that the lifting seat 10 does not shake when pressing down to receive the lunch box. Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when the drive motor 2 rotates forward, the film roller 1 begins to unwind the plastic film 3. At the same time, the moving cylinder 6 extends its piston rod forward, driving the connecting frame 7 and the two sets of vacuum suction cups 8 to contact the two sides of the plastic film 3 and adhere and fix it. Then the moving cylinder 6 retracts, and the vacuum suction cups 8 pull the two sides of the plastic film 3 outward to form an opening. At this time, the hydraulic rod 16 drives the lifting seat 10 to rise, and the steering motor 11 drives the film pulling plate 9 to rotate slightly, so that it clamps the edge of the opened plastic film 3 from the inside. As the hydraulic rod 16 descends, it covers the disposable lunch box set located on the conveyor table 15 with the plastic film 3, thereby realizing rapid film opening and covering during the lunch box transportation process.

[0021] A grooving cylinder 14 is fixedly installed on the rear left side of the inner wall of the bracket 4. A grooving plate 13 is fixedly connected to the piston end of the grooving cylinder 14. The grooving cylinder 14 is model SMC CD85N16-30-B. It is used to push the grooving plate 13 to cooperate with the hot melt knife 12 to complete the sealing and cutting. A servo motor 20 is fixedly installed on the rear right side of the inner wall of the bracket 4. A ball screw 18 is fixedly connected to the output shaft of the servo motor 20. A screw sleeve 19 is sleeved on the outside of the ball screw 18. The bottom end of the screw sleeve 19 is fixedly connected to the hot melt knife 12. The servo motor 20 is model MHMD042G1U. It drives the ball screw 18 to achieve precise translation of the hot melt knife 12. With the help of an encoder, the cutting position can be precisely controlled. The hot melt knife 12 is model HSK-200W. The heating temperature range is 100~250 ℃. It quickly heat-seals and cuts the plastic film 3 to avoid yellowing of the seal or rough edges of the cut. Specifically, such as Figure 1 and Figure 5 As shown, after the food container is covered with film, it continues to move forward along the conveyor 15. When it reaches the area between the cutting groove plate 13 and the hot melt knife 12, the drive motor 2 pulls back the plastic film 3 by a section, so that the length of the plastic film 3 covered on the food container reaches the preset value. At this time, the servo motor 20 drives the ball screw 18 to rotate, and the screw sleeve 19 moves accordingly, driving the hot melt knife 12 to move closer to the cutting groove plate 13. At the same time, the cutting groove cylinder 14 pushes the cutting groove plate 13 to move towards the hot melt knife 12. The hot melt knife 12 and the cutting groove plate 13 form a clamping engagement, and the hot melt cutting of the plastic film 3 is completed at the moment of contact, and a sealing opening is formed at the cutting point to ensure the sealing and neatness of the packaging.

[0022] A conveyor 15 is installed at the bottom of the bracket 4. An operating table 23 is installed behind the conveyor 15. A flip motor 22 is installed at one end of the operating table 23 near the conveyor 15. The output shaft of the flip motor 22 is fixedly connected to a flip table 21. The flip motor 22 is an SMC LEY25A-150, which enables the flip table 21 to switch precisely between horizontal and inclined. The flip table 21 is located between the conveyor 15 and the operating table 23. A rotary motor 24 is fixedly connected to the bottom of the operating table 23. The output shaft of the rotary motor 24 is fixedly connected to a turntable 25. The turntable 25 is rotatably connected to the top of the operating table 23. The rotary motor 24 is an SMC LER20C, and the rotation angle can be set to 90° for the turntable 25 to be quickly positioned within a fixed angle. Specifically, such as Figure 1 and Figure 6As shown, the sealed lunch box continues to be conveyed along the conveyor 15 to the flipping table 21. Under the action of gravity, it slides onto the flipping table 21. The flipping motor 22 starts, driving the flipping table 21 to flip around the horizontal axis, so that the lunch box changes from horizontal to vertical, making it easier for it to fall smoothly from the flipping table 21 onto the turntable 25. After that, the rotary motor 24 drives the turntable 25 to rotate horizontally by 90°, so that the open side of the lunch box faces the worker, so that the worker can easily complete the sealing at the operating table 23, thereby reducing the worker's bending or twisting movements and improving work comfort.

[0023] Furthermore, the drive motor 2, moving cylinder 6, vacuum suction cup 8, steering motor 11, hot melt knife 12, knife groove cylinder 14, hydraulic rod 16, servo motor 20, tilting motor 22, and rotating motor 24 are all electrically connected to the PLC controller 17.

[0024] Working principle: When the drive motor 2 rotates forward, the film roller 1 begins to unwind the plastic film 3. Simultaneously, the moving cylinder 6 extends its piston rod forward, driving the connecting frame 7 and two sets of vacuum suction cups 8 to contact and fix the plastic film 3 on both sides. Then, the moving cylinder 6 retracts, and the vacuum suction cups 8 pull the plastic film 3 outward to form an opening. At this time, the hydraulic rod 16 drives the lifting seat 10 to rise, and the steering motor 11 drives the film-pulling plate 9 to flip and clamp the edge of the opened plastic film 3. As the hydraulic rod 16 descends, it covers the disposable lunch box set located on the conveyor table 15, thus achieving rapid film opening and covering during lunch box transport. After the lunch box is covered with film, it continues to move forward along the conveyor table 15. When it reaches between the knife slot plate 13 and the hot melt knife 12, the drive motor 2 pulls back the plastic film 3 by a section, so that the length of the plastic film 3 covering the lunch box reaches the preset value. At this time, the servo... The servo motor 20 drives the ball screw 18 to rotate, and the screw sleeve 19 moves accordingly, causing the hot melt knife 12 to move closer to the knife groove plate 13. At the same time, the knife groove cylinder 14 pushes the knife groove plate 13 to move towards the hot melt knife 12. The hot melt knife 12 and the knife groove plate 13 form a clamping engagement, and the plastic film 3 is cut off by hot melt at the moment of contact, forming a seal at the cut. The sealed lunch box continues to be transported along the conveyor table 15 to the flipping table 21. Under the action of gravity, it slides onto the flipping table 21. The flipping motor 22 starts, driving the flipping table 21 to flip around the horizontal axis, so that the lunch box changes from horizontal to vertical. After the lunch box falls smoothly onto the turntable 25, the rotary motor 24 drives the turntable 25 to rotate horizontally by 90°, so that the open side of the lunch box faces the worker, making it convenient to tie at the operating table 23, improving work comfort and packaging efficiency, and realizing automated continuous operation.
