Description

Technical Field

[0001] This utility model relates to the field of sealing technology for powder packaging machines, and in particular to a sealing structure for powder packaging machines. Background Technology

[0002] The sealing structure of a powder packaging machine refers to the mechanism used to seal the packaging bags containing powder. It is usually composed of multiple parts and achieves the sealing operation of the packaging bags through a series of actions and principles to ensure that the powder does not leak during storage and transportation, thus maintaining the quality and integrity of the product.

[0003] Currently, when using vacuum packaging machines, simple pressure strips are used to press the opening of the packaging bag during the sealing process. However, due to the thickness of the packaged product and the vacuuming process, the opening of the packaging bag is prone to stretching, deformation, and folding. This can lead to folding or poor heat sealing of the sealing heat-sealed part, resulting in quality problems such as product deterioration during storage and transportation.

[0004] An existing patent (publication number: CN215323623U) discloses a device for improving the sealing effect of a packaging machine, including a support frame, an operation panel, a vacuum packaging machine, and a control panel. The operation panel is located on the top outer wall of the support frame, the vacuum packaging machine is located on one side of the top outer wall of the operation panel, and the control panel is located on one side wall of the support frame. An electromagnet assembly and a sealing support assembly are fixedly installed on one side of the top outer wall of the operation panel, and the sealing support assembly is located on one side of the electromagnet assembly. The vacuum packaging machine and the electromagnet assembly are electrically connected to the control panel. The electromagnet assembly includes a lower fixed plate, a fixing groove is formed on the top outer wall of the lower fixed plate, a lower electromagnet is fixedly installed inside the fixing groove, a spring is fixedly installed on the top outer wall of the lower fixed plate, an upper fixed plate is fixedly connected to the top of the spring, and an upper electromagnet is fixedly installed on the bottom outer wall of the upper fixed plate, with the upper electromagnet located directly above the lower electromagnet.

[0005] To address the aforementioned issues, existing patents offer solutions, but these solutions have certain limitations in use. The packaging machine takes a long time to seal, affecting packaging efficiency, and the seal may not be secure when the temperature is too low, posing a risk of powder leakage and making cleaning difficult.

[0006] Therefore, a sealing structure for a powder packaging machine is proposed. Utility Model Content

[0028] 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.

[0029] Please see Figure 1-7 The present invention provides the following technical solution:

[0030] A sealing structure for a powder packaging machine includes a machine body 1. Two mounting plates 3 and a movable frame 2 are fixedly connected to the front side of the machine body 1. Two sealing frames 6 and a collecting mechanism 5 are provided on the opposite side of the two mounting plates 3. A sealing mechanism 4 is provided on the opposite side of each of the two sealing frames 6.

[0031] The sealing mechanism 4 includes a connecting plate 401, an auxiliary heating plate 402, a limiting frame 403, a aligning plate 404, and a heating block 405. The side of the connecting plate 401 closest to the auxiliary heating plate 402 is fixedly connected to the auxiliary heating plate 402. The two auxiliary heating plates 402 are in contact with each other on opposite sides. The top of the limiting frame 403 is in contact with the bottom of the connecting plate 401. The side of the aligning plate 404 closest to the limiting frame 403 is fixedly connected to the limiting frame 403. The side of the limiting frame 403 closest to the sealing frame 6 is fixedly connected to the sealing frame 6. The top of the heating block 405 is fixedly connected to the bottom of the limiting frame 403.

[0032] In this embodiment: by fixing the side of the limiting frame 403 near the sealing frame 6 to the sealing frame 6, the limiting frame 403 can easily fix and support the heating block 405 and the aligning plate 404 through the sealing frame 6. Under the limitation of the aligning plate 404, the two connecting plates 401 can easily drive the auxiliary heating plate 402 to contact the surface of the sealing bag, thereby facilitating the preheating of the sealing bag to a certain temperature and accelerating the sealing efficiency of the sealing frame 6 sealing the sealing bag through the heating block 405.

[0033] Specifically, such as Figure 2 , Figure 6 As shown, the collection mechanism 5 includes a collection rack 501 disposed between the bottoms of two sealing racks 6, and a collection groove 503 is provided on the top of the collection rack 501.

[0034] Specifically, such as Figure 6 As shown, the inside of the collection rack 501 is provided with four screws 15. The top of the screws 15 extends into the inside of the heating block 405 and is threadedly connected to the inside of the heating block 405. Two inclined blocks 502 are fixedly connected to the opposite side of the two sealing racks 6.

[0035] Specifically, such as Figure 6As shown, two locating rods 506 are fixedly connected to the right side of the collection rack 501. A limiting block 505 is slidably connected to the surface of the locating rod 506, and a limiting pad 504 is fixedly connected to the left side of the limiting block 505.

[0036] In this embodiment: by slidingly connecting the surface of the alignment rod 506 with the interior of the limiting block 505, the collection rack 501 can be easily moved by the alignment rod 506, and the inclined block 502 can be fixedly connected to the sealing rack 6 by being close to the side of the sealing rack 6. This makes it easy for the powder to move into the interior of the collection trough 503 through the inclined block 502, thus achieving the effect of convenient powder collection.

[0037] Specifically, such as Figure 5 As shown, the top of the limiting frame 403 has two sliding grooves 13, and a sliding block 14 is slidably connected inside the sliding groove 13. The top of the sliding block 14 is fixedly connected to the bottom of the connecting plate 401.

[0038] Specifically, such as Figure 3 , Figure 5 As shown, two first sliding columns 11 and four adjusting brackets 12 are fixedly connected to opposite sides of the two connecting plates 401. The surface of the first sliding column 11 is slidably connected to the inside of the sealing frame 6. The inside of the mounting plate 3 is fixedly connected to a first electric telescopic column 9 and four auxiliary rods 10. The side of the auxiliary rods 10 closest to the sealing frame 6 is fixedly connected to the sealing frame 6.

[0039] In this embodiment: by making the surface of the sliding block 14 slide in connection with the interior of the sliding groove 13, the sliding groove 13 can be conveniently limited by the sliding block 14 to the connecting plate 401, and the surface of the first sliding column 11 can be slidably connected with the interior of the sealing frame 6, thereby making it convenient for the first sliding column 11 to limit the movement of the connecting plate 401, thus achieving the effect of limiting the movement of the connecting plate 401.

[0040] Specifically, such as Figure 2 , Figure 7 As shown, a cutting frame 7 and a support block 18 are respectively provided on one side of the two mounting plates 3 facing each other. Two second electric telescopic columns 16 are fixedly connected to the left side of the cutting frame 7.

[0041] Specifically, such as Figure 7 As shown, a cutting block 17 is fixedly connected to the left side of the support block 18, and two second sliding columns 8 are slidably connected inside the cutting block 17.

[0042] In this embodiment: by fixing the right side of the second electric telescopic column 16 to the left side of the cutting frame 7, the second electric telescopic column 16 can easily drive the cutting frame 7 to move, and the surface of the second sliding column 8 can slide to connect with the surface of the cutting block 17, thereby facilitating the cutting frame 7 to cut the sealed bag through the cutting block 17, achieving the effect of convenient cutting of the sealed bag.

[0043] Working principle: When the sealing frame 6 seals the bag containing powder, the bag is moved to the opposite side of the two heating blocks 405 by the alignment plate 404. Under the limit of the adjusting frame 12 and the first sliding column 11, the two connecting plates 401 drive the auxiliary heating plate 402 to contact the surface of the bag, thus facilitating the preheating of the bag to a certain temperature and speeding up the sealing efficiency of the sealing frame 6 sealing the bag by the heating blocks 405. At the same time, the left sealing frame 6 drives the collecting frame 501 to contact the limiting pad 504 through the alignment rod 506. Under the limit of the limiting block 505, the collecting frame 501 collects the powder through the collecting groove 503, thereby reducing the random spillage of powder. This solves the problems of existing packaging machines having long sealing time, affecting packaging efficiency, and weak sealing at low temperatures, which poses a risk of powder leakage and is difficult to clean.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
