Description

Technical Field

[0001] The present invention relates to the technical field of packaging production equipment, and more specifically, in particular to a high-efficiency vacuum vertical packaging machine. Background Art

[0002] Packaging machines are production equipment used to package products in film bags to protect and beautify them. There are many types of packaging machines, which can be used to prepare ingredients and package products according to different production needs. Packaging machines have been widely used in many different production fields, including parts and components, food, medicine and other fields.

[0003] During the production and processing of food and medicine packaging, since the packaging objects (food, medicine) have high requirements for the packaging storage environment, and in order to extend the storage time of the packaging objects and reduce the reaction between the bacteria in the air in the packaging bag and the packaging objects, most of them need to further adopt vacuum operation.

[0004] The existing packaging machines are all assembly-line structures with complex equipment mechanisms. A lot of noise is generated during the processing. Each processing step, such as packaging of packaging bags, distribution of materials, vacuuming inside bags, and packaging cutting, requires independent processing equipment to complete the processing, resulting in a large equipment size. A large amount of production space is required. The vacuuming process and packaging process are separate steps, and the production and processing continuity is poor. The sealing process is performed after the vacuuming operation is completed, resulting in poor vacuum sealing of the packaging bags, which is prone to leakage. Vacuuming failure affects the storage of packaged products, and the sealing process effect is not ideal. In addition, the pressure difference during the vacuuming process will cause the packaging bags to shrink and deform, affecting the molding and cutting quality, resulting in large differences in the quality of the finished products. In addition, the production requires a lot of equipment, the overall production debugging and setting operation is cumbersome, troubleshooting is difficult, and later maintenance is difficult.

[0005] In view of this, it is necessary to develop a new packaging production and processing equipment, which not only needs to be able to reduce the size of the equipment, but also needs to be able to further improve the vacuum sealing effect of the ingredients in the packaging production while ensuring the quality of the ingredients packaging and sealing, thereby improving the final quality of the product and creating better production benefits for packaging manufacturers.

[0054] First embodiment:

[0055] During production, the film carrier roller 12 equipped with the packaging film roll is installed in the film carrier rolling groove of the film placing frame 11, and the limiting width of the limiting ring of the film feeding limiting device arranged on the film guide roller is adjusted according to the specifications of the film material. The film material is successively passed through the film feeding guide roller 13 and the film clamping guide roller 15, the film feeding pressure roller 16, the film guide roller, the film feeding detector 10 and the film guide roller to be pulled into the former 411, and the packaging film material is initially shaped by the former 411. The limiting ring of the film feeding limiting device can be adjusted according to the specifications of the film material used for processing. The distance installed on both sides of the film guide roller is adjusted, and the position of the film material is limited by the limiting rings on both sides.

[0056] The packaged materials are placed in the storage barrel 21 , and fall into the feed trough 22 from the discharge outlet of the storage barrel 21 , and are temporarily stored in the feed trough 22 . The feed port of the feed trough 22 is arranged above the rotating drop trough 32 .

[0057] The production operator sets the processing parameters of the vacuum forming mechanism 4, the sealing mechanism 5, the clamping and sealing mechanism 6 and the punching and recovery mechanism 7 through the control operation panel 81 according to the data of the produced product, and the production and processing settings are ready.

[0058] The operator starts the high-efficiency vacuum vertical packaging machine.

[0059] The sealing part 51 of the sealing mechanism 5 performs side sealing and forming on the bag body preformed by the former 411, and the sealing pressing plate 64 of the clamping and sealing and pulling mechanism 6 seals the protruding part below the former 411, and the rotating blanking chute 32 rotates. The rotating blanking chute 32 continues to rotate to drop the material stored in the storage cavity of the quantitative blanking part 36 through the blanking port along the blanking conduit 33 through the blanking cavity 412 of the former 411 into the bag body with the bottom sealed and stored above the sealing pressing plate 64. After the sealing is completed, the lifting device 61 drives the sealing pressing plate 64 to clamp and pull the bag body to move down a preset stroke through the sealing and pulling frame 62, and the sealing pressing plate 64 releases the bag body. After the bag is clamped, the lifting device 61 rises and resets through the sealing and pulling frame 62 and the lower clamping part 66. After the origin detector 601 detects that the lifting connecting frame 69 has moved to the initial sealing position, the lifting device 61 is controlled to stop moving. At the same time, the sealing drive part 63 drives the upper clamping plate 67 of the upper clamping part 65 and the lower clamping drive part drives the lower clamping block 68 to clamp in the middle. The upper clamping plate 67 and the lower clamping block 68 will first clamp and smooth the bag body respectively, so that the bag body remains straight to complete the vacuum sealing process. The vacuum action will not cause shrinkage and deformation due to the different air pressure inside and outside the bag body, which will affect the quality of the product after sealing and punching. Then the clamping plate 432 is clamped towards the middle, and the bag body is fitted and sealed with the outer wall of the air suction port of the vacuum tube 413 through the sealing gasket 433. The vacuum driver sets the vacuum tube 413 on both sides of the feeding cavity 412 to evenly extract the air inside the clamped bag body according to the preset vacuum parameters to form a vacuum state. After the vacuum extraction is completed, the sealing drive unit 63 continues to drive the sealing plate 64 to move towards the middle, and the sealing plate 64 seals and preserves the bag body. After the sealing is completed, the lifting device 61 drives the sealing plate 64 to clamp and pull the bag body down to a preset stroke through the sealing and pulling frame 62, and controls the sealing plate 64 to release the clamping and move upward to reset, and performs the smoothing, clamping and sealing operations on the next bag that has been vacuumed according to the previous vacuum processing steps, and continues to pull down to complete the vacuum-sealed and packaged bag. After being pulled down, the bag body enters between the punching block 74 and the punching discharge port 75 of the punching frame 72 from the lower bag opening 77 of the lower bag guiding part 76 along the lower bag guide plate 78, and the punching driving part 73 drives the punching block 74 to punch and cut the bag body that has completed the vacuum sealing packaging. The product after punching falls into the finished product collection part below, and the waste of the broken bag body is flushed from the punching discharge port 75 and falls into the waste dropping chute 79. After being blocked by the waste baffle 70, it slides down along the downwardly inclined waste dropping chute 79 to the waste collection part, completing the waste collection without causing pollution to the production environment.

[0060] During the production process, the detector of the material remaining detection device 34 detects the remaining amount of the filling material in the rotating blanking trough 32. When the remaining amount of the filling material in the rotating blanking trough 32 is lower than the preset value, the vibration feeder 23 of the feeding mechanism 2 is controlled to operate, and the stored material in the backward inclined feeding trough 22 is replenished into the rotating blanking trough 32, and the quantitative blanking part 36 in the rotating blanking trough 32 continues to store materials.

[0061] During the production process, when the film material is driven by the film feeding motor 14 to rotate the film feeding guide roller 13 and the film clamping guide roller 15 is loosened, the film feeding pressure roller 16 pressed on the film material slides down along the film feeding control frame 17. After the film feeding pressure roller 16 slides down to the bottom of the film material feeding stop detector 18 and detects it, the film material feeding stop detector 18 controls the film feeding motor 14 to stop the film feeding action; after the film material is pulled and processed, when the film material is pulled, the film feeding pressure roller 16 pressed on the film material rises along the film feeding control frame 17 with the film material. After the film feeding pressure roller 16 rises to the top of the film material feeding stop detector 18 and detects it, the film material feeding stop detector 18 controls the film feeding motor 14 to resume the film feeding action and replenish the film release and module taking amount. When the film feeding detector 10 detects that there is no film material on the detection crossbar, the film feeding detector 10 controls the film feeding motor 14 to stop running and issues a material shortage indication.

[0062] During the production process, the anti-blocking device 42 works, and the anti-blocking vibration part 421 vibrates the former 411 through the anti-blocking connection part 422 to prevent blocking, so as to prevent the filling material from entering the discharge cavity 412 of the former 411 and adhering to and accumulating inside, causing blockage or affecting the amount of the filling material, thereby ensuring smooth production and the quality of the products leaving the factory.

[0063] By repeating the above production and processing steps, products with good sealing, neat packaging and ideal quality can be manufactured quickly and stably.

[0064] Second embodiment:

[0065] This embodiment is similar to the first embodiment, except that, in this embodiment, when it is necessary to switch to the production of products of other specifications, there is no need to replace the entire machine. According to the specifications of the film material of the new product, the limiting distance between the limiting rings of the film feeding limiting device installed on both sides of the film guide roller is adjusted to adapt to the specifications of the film material for processing the new product, the quantitative blanking part 36 with a corresponding blanking storage amount is replaced, the former 411 is replaced, the former 411 and the anti-blocking connecting part 422 are recombined, the origin detection position of the origin detector 601 is adjusted, and the punching frame 72 is adjusted to the front and rear and up and down positions through the position adjustment mechanism to the appropriate punching position for processing the new product, so that the lower bag guide part 76 is aligned and arranged below the blanking end of the new former 411.

[0066] Furthermore, the outer wall of the blanking bracket 30 in this embodiment is provided with a rotating pressing portion 38 through a threaded connection, the upper end of the rotating pressing portion 38 is arranged to fit the bottom of the mounting rod of the blanking plate 31, a rotating holding column 39 is arranged on the outer side of the rotating pressing portion 38, and the mounting rod is fixedly mounted on the blanking bracket 30 through a locking member.
