Description

Technical Field

[0001] This invention relates to the field of vacuum packaging equipment, specifically a high-speed vacuum packaging device. Background Technology

[0002] High-speed vacuum packaging equipment is a key type of automated production equipment. Its core function is to inhibit microbial growth and slow down oxidation by quickly removing air from the packaging and sealing it immediately, thereby significantly extending the shelf life of the product and maintaining its quality. Enterprises widely adopt this type of equipment because it can not only carry out large-scale, standardized, continuous production at a speed far exceeding that of manual labor, thus greatly improving efficiency and reducing labor costs, but also make the product shape regular and compact through functions such as six-sided shaping, thereby optimizing warehousing and logistics efficiency and increasing shelf appeal.

[0003] Existing high-speed vacuum packaging equipment, especially the mainstream rotary models, works on the principle of a multi-station continuous rotating worktable. Through a programmable logic controller, a series of mechanical actions are precisely synchronized, decomposing and automating the complex packaging process. The equipment starts with automatic bag picking and opening, and then sequentially sends the packaging bags to key stations such as filling, bag mouth shaping and dust removal, vacuuming, and heat sealing. Finally, after cooling and shaping, the finished product is output. Its core lies in placing the packaging in a sealed vacuum chamber, quickly removing the air to achieve a vacuum state, and immediately sealing the bag mouth through heat pressing. The entire process is seamless, thereby achieving efficient, continuous, and standardized fully automatic vacuum packaging production.

[0004] Although high-speed vacuum packaging equipment is renowned for its production efficiency, the complexity of mold and feed bar replacement processes in practical applications severely impacts its practical value. When the production line needs to switch to products of different sizes or specifications, operators must interrupt production and perform a series of tedious and time-consuming operations. This downtime, which can last for tens of minutes or even longer, completely negates the efficiency advantage brought by the high speed of the equipment itself. As a result, it is inadequate to meet the current market's demand for flexible production of small batches and multiple varieties. Therefore, the slowness in operation and the speed in performance create a sharp contradiction, weakening the equipment's production flexibility and overall operational efficiency, making it a bottleneck in the entire production chain.

[0022] Please see the appendix Figure 1 -Appendix Figure 6 This invention provides a high-speed vacuum packaging device, including a chassis 1, a control console 2, and a protective box 8.

A mold 11 is slidably connected inside each mounting seat 10, and a fixing component is located on the top of each mounting seat 10. Multiple telescopic rods 19 are fixedly connected inside the protective box 8. A loading box 20 is fixedly connected to the output end of every two telescopic rods 19. A limiting strip 21 is fixedly connected to the top of each loading box 20. A feeding strip 22 is slidably connected to the bottom of each limiting strip 21. A connecting strip 23 is fixedly connected to the top of each feeding strip 22, and a connecting component is located inside each limiting strip 21. A thermostatic assembly is installed on the top of the chassis 1, an air jet assembly is installed inside the protective box 8, a conveying assembly is installed inside the chassis 1, a lifting rod 32 is fixedly connected to the top of the bracket 9, and a pushing assembly is installed inside the chassis 1. The control components include a display screen 3, multiple buttons 4, and an emergency stop switch 5. One side of the display screen 3 is electrically connected to one side of the control panel 2. One end of each button 4 is electrically connected to one side of the control panel 2. One end of the emergency stop switch 5 is electrically connected to one side of the control panel 2. The maintenance components include multiple hinges 6 and multiple maintenance doors 7. The chassis 1 is connected to the multiple maintenance doors 7 via multiple hinges 6. One side of each maintenance door 7 is rotatably connected to one side of the chassis 1. The hot pressing components include two protective shells 29, two hydraulic columns 30, and two hot pressing plates 31. The top of each protective shell 29 is fixedly connected to the top of the inner wall of the chassis 1. The outer wall of each hydraulic column 30 is fixedly connected to the inside of the protective shell 29. The top of the hot press plate 31 is slidably connected to the top of the inner wall of the housing 1. The output end of each hydraulic column 30 is connected to one side of the hot press plate 31. The conveying assembly includes a lifting frame 34, a buffer pad 35 and a conveyor belt 37. The inner side of the lifting frame 34 is slidably connected to one side of the support 9. The bottom of the lifting frame 34 is fixedly connected to a second lifting rod 33. The output end of the second lifting rod 33 is connected to the bottom of the lifting frame 34. One hydraulic rod 38 is fixedly connected to one side of the lifting frame 34. The output end of the first hydraulic rod 38 is connected to the bottom of the conveyor belt 37. The bottom of the buffer pad 35 is fixedly connected to the top of the lifting frame 34. Two rotating shafts 36 are fixedly connected to the top of the lifting frame 34. The two sides of the conveyor belt 37 are fixedly connected between the rotating shafts 36. Specifically, firstly, a worker places a packaging bag over the feeding strip 22. Then, the telescopic rod 19 is activated to cause the loading box 20 containing rice to descend vertically, so that the feeding strip 22, along with its outer packaging bag, is placed into the mold 11 below. Immediately afterward, the rice grains inside the loading box 20 slide into the feeding strip 22 and fill the entire packaging bag. Then, the telescopic rod 19 reverses its direction, pulling the feeding strip 22 out of the rice bag. At the same time, the vibration motor 54 starts working to shake the rice grains inside the packaging bag evenly.

[0023] Once the rice grains are evenly filled, the support 9 slides backward along the preset track, transporting the mold 11 to the working position aligned with the hot press plate 31. Then, the lifting rod 32 is activated, vertically lifting the entire mold 11 upward, so that the bag opening enters between the two hot press plates 31. The hydraulic column 30 then applies pressure to drive the hot press plates 31 to close, fusing the bag opening with high temperature and high pressure.

[0024] After heat sealing, the heat press plate 31 does not immediately release. Instead, the support 9 is lowered by the lifting rod 32, and then the support 9 returns to its initial position. At this time, the buffer pad 35 has moved to the bottom of the heat press plate 31. The lifting rod 33 then drives the lifting frame 34 to move upward to meet and support the bottom of the packaged product. Then, the hydraulic rod 38 starts to push the conveyor belt 37 to adhere to the side of the product under the constraint of the rotating shaft 36. After that, the heat press plate 31 slowly releases. Finally, the hydraulic rod 38 retracts inward and uses the traction force of the conveyor belt 37 to lay the product down. As the lifting frame 34 retracts and returns to its original position, when the next unsealed product is lifted, the conveyor belt 37 starts to send the packaged finished product out of the machine box 1.

[0025] Please see the appendix Figure 2 -Appendix Figure 5 Each fixing component includes a fixing shell 12 and an extrusion plate 15. The bottom of the fixing shell 12 is fixedly connected to the top of the mounting base 10. A sliding shell 13 is slidably connected inside the fixing shell 12. A limit strip 14 is fixedly connected to one end of the sliding shell 13. One side of the extrusion plate 15 is fixedly connected to the other end of the sliding shell 13. Multiple positioning posts 16 are fixedly connected to one side of the extrusion plate 15. A connecting rod 17 is fixedly connected to one side of the extrusion plate 15. A pull ring 18 is rotatably connected to one end of the connecting rod 17. A second spring 55 is provided on the outer wall of the connecting rod 17. One end of the second spring 55 is fixedly connected to the inside of the extrusion plate 15, and the other end of the second spring 55 is fixedly connected to the inside of the fixing shell 12. Each connecting component includes a fixing strip 24 and two fixing blocks 26. The outer wall of the fixing strip 24 is slidably connected to the inside of the limiting strip 21. An extrusion strip 25 is fixedly connected to the inner wall of the fixing strip 24. The outer wall of each fixing block 26 is slidably connected to the inside of the limiting strip 21. One end of each fixing block 26 is slidably connected to the inside of the fixing strip 24. A sliding post 27 is fixedly connected to the top and bottom of each fixing block 26. A spring 28 is provided on one side of each sliding post 27. One end of each spring 28 is fixedly connected to the inside of the sliding post 27, and the other end of each spring 28 is fixedly connected to the inside of the limiting strip 21. Specifically, when it is necessary to replace mold 11, the operator first holds the pull ring 18 and pulls it outward, so that the positioning post 16 on one side of the extrusion plate 15 disengages from the slot of mold 11, thereby completely unlocking mold 11. Then, the operator holds the edge of mold 11 with both hands and pulls it out of the mounting base 10. Then, a set of mold 11 with matching size is pushed into it. When mold 11 touches the deepest part of mounting base 10, the built-in spring 2 55 will release the elastic force to drive the positioning post 16 to pop out and lock into the preset hole of the new mold 11, thus completing the replacement of mold 11. When the feeding strip 22 needs to be replaced, the operator inserts their fingers into the groove on the surface of the fixing block 26 and gently pulls it outward to disengage its front end from the fixing strip 24. Then, the operator grasps the bottom of the fixing strip 24 and pulls it outward, causing the connecting strip 23 at the top of the feeding strip 22 to apply pressure to the extrusion strip 25, causing it to deform instantly and release the lock, thus unlocking the entire connecting mechanism. After unlocking, the old feeding strip 22 is pulled out of the limiting strip 21 and replaced with a feeding strip 22 that matches the new mold 11. The connecting strip 23 at the top of the old feeding strip 22 is inserted into the limiting strip 21. Finally, the operation is reversed, and the fixing block 26 is pulled again to insert the fixing strip 24 back into its original position, thus completing the entire replacement process.

[0026] Please see the appendix Figure 7 and attached Figure 8 The jet assembly includes an air guiding module and an air blowing module. The air guiding module includes a fixed plate 39, two air pumps 40, and two connecting hoses 41. The outer wall of the fixed plate 39 is slidably connected to the inside of the protective box 8. The outer wall of each air pump 40 is fixedly connected to the inside of the protective box 8. One end of each connecting hose 41 is fixedly connected to the output end of the air pump 40. Two lifting columns 42 are fixedly connected to the top of the chassis 1. The output end of each lifting column 42 is connected to the bottom of the fixed plate 39. The other end of each connecting hose 41 is fixedly connected to a delivery pipe 43. The outer wall of each delivery pipe 43 is fixedly connected to the inside of the fixed plate 39. The air blowing module includes a connecting seat 44 and a nozzle 45. The top of the connecting seat 44 is fixedly connected to the bottom of the delivery pipe 43, and the top of the nozzle 45 is fixedly connected to the bottom of the connecting seat 44. Multiple air jet pipes 46 are fixedly connected inside the nozzle 45, and the air jet pipes 46 are arranged in a ring array inside the connecting seat 44.

[0027] Specifically, when the mold 11 carrying the rice bag is lifted upwards, allowing the bag opening to enter the working area of ​​the hot press plate 31, the lifting column 42 starts, driving the fixed plate 39 and the connected conveying pipe 43 to descend vertically, allowing the nozzle 45 to extend into the opening of the packaging bag. Immediately afterwards, the air pump 40 starts, pumping airflow into the conveying pipe 43 and spraying it out from the end air jet pipe 46. This airflow blows off the rice grains adhering to the inner wall of the top of the packaging bag, mixing them with the rice grains at the bottom. After the cleaning task is completed, the air pump 40 stops supplying air, and at the same time, the lifting column 42 reverses, pulling the nozzle 45 out of the bag. The hydraulic column 30 then starts, driving the hot press plate 31 to close, sealing the packaging bag with heat.

[0028] Please see the appendix Figure 9 and attached Figure 10The driving component includes a rotating shaft 47, a reset plate 48, and a second hydraulic rod 51. The outer wall of the rotating shaft 47 is rotatably connected to the top of the lifting frame 34. The bottom end of the reset plate 48 is fixedly connected to the top of the rotating shaft 47. A fixed seat 49 is fixedly connected to one side of the lifting frame 34. A heat sink 50 is fixedly connected to the top of the fixed seat 49. The outer wall of the second hydraulic rod 51 is fixedly connected to the inside of the heat sink 50. A docking seat 53 is fixedly connected to one side of the reset plate 48. A connecting block 52 is rotatably connected inside the docking seat 53. One side of the connecting block 52 is fixedly connected to the output end of the second hydraulic rod 51.

[0029] Specifically, when the conveyor belt 37 flips upward under the drive of hydraulic rod 38 to receive the heat-sealed product, the hot press plate 31, having completed its task, slowly releases under the command of hydraulic column 30. At this instant, hydraulic rod 51 starts, and the thrust it generates is transmitted through connecting block 52 and docking seat 53, pushing the reset plate 48 to rotate at a small angle, applying a guiding force to the heat-sealed product, ensuring that the packaged product tilts to one side of the conveyor belt 37, eliminating the risk of the product falling backward and crashing into the machine housing 1 due to instability, thus damaging the equipment.

[0030] Working principle: In the process of using the high-speed vacuum packaging equipment, the packaging bag is first put on the feeding strip 22, and then the telescopic rod 19 is activated to move the loading box 20 downward, so that the packaging bag outside the feeding strip 22 enters the mold 11. Then the equipment is activated to let the rice inside the loading box 20 enter the feeding strip 22. Then the telescopic rod 19 is activated again to pull the feeding strip 22 out from the inside of the packaging bag. At the same time, the vibration motor 54 is activated to shake the rice inside the packaging bag evenly. When the rice is evenly shaken, the support 9 begins to move backward so that the position of the mold 11 is aligned with the position of the hot press plate 31. Then the lifting rod 32 is activated to lift the mold 11 and let the top of the packaging bag enter between the hot press plates 31. Then the hydraulic column 30 is activated to push the two hot press plates 31 to heat seal the top of the packaging bag. After heat sealing, the hot press plate 31 will not be released temporarily. First, the lifting rod 32 will be activated to move it downwards to lower the bracket 9. Then, the bracket 9 will be activated to move it to its initial position, aligning the position of the buffer pad 35 with that of the hot press plate 31. Next, the lifting rod 33 will be activated to lift the lifting frame 34, so that the bottom of the heat-sealed product falls on top of the buffer pad 35. Then, the hydraulic rod 38 will be activated to make the conveyor belt 37 fit against one side of the product under the constraint of the rotating shaft 36. Then, the hydraulic column 30 will be activated to release the hot press plate 31 and release the heat-sealed product. Then, the hydraulic rod 38 will retract inwards, causing the conveyor belt 37 to move the product downwards and flatten it. Then, the lifting rod 33 will retract inwards to move the lifting frame 34 downwards to return it to its original position. When the mold 11 lifts the packaging bag and rice again, the conveyor belt 37 will be activated to send the packaged product out of the machine box 1. When it is necessary to replace mold 11, first hold pull ring 18 and pull it outward, so that extrusion plate 15 moves to the side of fixed shell 12 to drive positioning pin 16 out of mold 11, thereby unlocking mold 11. Then, the operator holds the edge of mold 11 and pulls mold 11 out of mounting base 10. Then, the new mold 11 is reinserted into mounting base 10. When the bottom of the new mold 11 enters the deepest part of mounting base 10, positioning pin 16 pops out under the action of spring 2 55 and is locked into the new mold 11, thereby completing the replacement of mold 11. When it is necessary to replace the feeding strip 22, first insert your finger into the groove on the surface of the fixing block 26 and pull the fixing block 26 outward so that its front end comes out of the fixing strip 24. Then, grasp the bottom of the fixing strip 24 and pull it outward so that the bottom of the connecting strip 23 at the top of the feeding strip 22 squeezes the extrusion strip 25, deforms it and releases it to unlock the connecting strip 23. Then, grasp the surface of the feeding strip 22 and pull it outward so that the connecting strip 23 comes out of the limiting strip 21. Then, take out the feeding strip 22 corresponding to the new mold 11 and insert the connecting strip 23 at its top into the limiting strip 21. Then, pull the fixing block 26 outward again and pick up the fixing strip 24 and insert it back into the limiting strip 21 to complete the replacement of the feeding strip 22. When the mold 11 moves the packaging bag and the rice inside upwards, causing the top of the packaging bag to extend into the hot press plate 31, the lifting column 42 is activated, causing the fixing plate 39 to move downwards, causing the conveying pipe 43 to move downwards, thereby causing the nozzle 45 to extend into the packaging bag. Then, the air pump 40 is activated to pump gas into the conveying pipe 43, which is then sprayed out from the air jet pipe 46, causing the rice adhering to the inner wall of the top of the packaging bag to fall off and mix with the rice at the bottom. Then, the air pump 40 stops supplying gas, and the lifting column 42 is activated to lift the fixing plate 39, causing the nozzle 45 to be pulled out from the packaging bag. Then, the hydraulic column 30 is activated to heat seal the packaging bag with the hot press plate 31. When the conveyor belt 37 rotates upward under the action of hydraulic rod 38, the hydraulic column 30 starts to release the hot press plate 31, and the hydraulic rod 51 starts to push the connecting block 52 to move outward, so that the docking seat 53 pushes the reset plate 48 to rotate, so that the packaged product moves to the side of the conveyor belt 37, preventing the product from falling into the machine box 1 and damaging the equipment.
