[0023] like Figure 1 and Figure 2 As shown, a sealing device for producing plastic packaging bags according to an embodiment of the present invention is illustrated, comprising: The base 1 has four support legs 6 fixedly installed at the top. The upper end of the four support legs 6 is fixedly installed with a shifting component 3. The shifting component 3 is designed to facilitate rotation and shifting after a set of plastic packaging bags is sealed, so as to seal the plastic packaging bags of the next station. Sealing mechanism 2 is located on one side of the switching component 3. The bottom end of the sealing mechanism 2 is fixedly installed on the top of the base 1. The sealing mechanism 2 is set on one side of the switching component 3. When the switching component 3 rotates, it can move directly downward to perform sealing work. The fixing component 4 is provided in several groups. The fixing components 4 are equidistantly arranged on the top of the switching component 3. The fixing components 4 are used to limit the packaging bag during sealing. The fixing components 4 are provided in several groups, which can fix several groups of plastic packaging bags at one time. When sealing by the sealing mechanism 2, it can save time and improve efficiency to a certain extent. The drive mechanism 5 is located at the bottom of the shifting component 3. The drive mechanism 5 is used to adjust the position of the shifting component 3. The drive mechanism 5 rotates the shifting component 3. After the plastic packaging bag is fixed by the fixing component 4, the drive mechanism 5 rotates it to the bottom of the sealing mechanism 2 to perform the sealing work.

[0024] In some examples, such as Figure 3 As shown, the switching component 3 includes a limiting barrel 31. The bottom end of the limiting barrel 31 is fixedly installed on the top of the four support legs 6. The upper inner wall of the limiting barrel 31 is provided with a placement groove 33. A rotating plate 32 is provided in the placement groove 33. A through groove 36 is provided in the middle of the bottom wall of the limiting barrel 31.

[0025] The support leg 6 is used to support the shifting component 3, which facilitates the installation of the drive mechanism 5. The placement groove 33 at the upper end of the limiting barrel 31 is used to place the rotating plate 32 to prevent the rotating plate 32 from shifting. At the same time, the through groove 36 at the bottom end of the limiting barrel 31 facilitates the installation of the drive mechanism 5.

[0026] In some examples, such as Figure 3 As shown, an annular groove 34 is provided at the bottom of the placement groove 33, and an annular plate 35 is fixedly installed at the bottom of the rotating plate 32. The annular plate 35 is located in the annular groove 34.

[0027] The annular plate 35 is located in the annular slot 34 and is driven to rotate by a drive mechanism 5. The annular slot 34 limits the position of the annular plate 35 to prevent shaking or loosening.

[0028] In some examples, such as Figure 3 As shown, the drive mechanism 5 includes a connecting column 54. One end of the connecting column 54 passes through the through groove 36 and is fixedly connected to the bottom end of the rotating plate 32. A bearing 55 is sleeved on the outer surface of the connecting column 54 located in the through groove 36. The inner ring surface of the bearing 55 is fixedly connected to the outer surface of the connecting column 54, and the outer ring surface of the bearing 55 is fixedly connected to the through groove 36.

[0029] One end of the connecting column 54 is fixedly connected to the bottom end of the rotating plate 32. When the other end rotates, it can drive the rotating plate 32 to rotate. The connecting column 54 and the bearing 55 work together to reduce friction to a certain extent.

[0030] In some examples, such as Figure 3 As shown, the drive mechanism 5 also includes a motor 51. The bottom end of the motor 51 is fixedly installed on the bottom wall of the limiting barrel 31. The output end of the motor 51 is fixedly connected to a drive wheel 52. A driven wheel 53 is meshed on one side of the drive wheel 52. The top end of the driven wheel 53 is fixedly installed on the bottom end of the connecting column 54.

[0031] When the output end of the motor 51 drives the driving wheel 52 to rotate, the driven wheel 53 meshing on one side rotates accordingly. The bottom end of the connecting column 54 is fixedly connected to the driven wheel 53. When the driven wheel 53 rotates, it drives the rotating plate 32 to rotate, which can rotate several sets of fixed components 4. When one set completes the sealing work through the sealing mechanism 2, the sealing work of the plastic packaging bag on the next set of fixed components 4 can be carried out through the driving mechanism 5.

[0032] In some examples, such as Figure 2 As shown, the sealing mechanism 2 includes a support plate 21. The bottom end of the support plate 21 is fixedly installed on the top end of the base 1. A connecting block 22 is fixedly installed on the top end of the support plate 21. A cylinder 23 is fixedly installed on the bottom end of one side of the connecting block 22. A heating plate 24 is fixedly installed on the output end of the cylinder 23.

[0033] The connecting block 22 facilitates the installation of the cylinder 23. The heating plate 24 installed at the bottom of the cylinder 23 moves downward through the cylinder 23 to press down and seal the plastic packaging bag on the fixing component 4. The heating plate 24 has a built-in heating tube that is electrically connected to the controller. The heating plate 24 presses down on the plastic packaging bag to melt and stick it, thus completing the sealing work.

[0034] In some examples, such as Figure 4 As shown, the fixing component 4 includes a placement plate 41, the bottom end of which is fixedly installed on the surface of the rotating plate 32. Fixing plates 42 are fixedly installed on both sides of the placement plate 41. A connecting plate 43 is fixedly installed on the top of the fixing plate 42. Two through holes 48 are opened on the surface of each connecting plate 43, and a moving rod 45 is slidably connected in each through hole 48.

[0035] When fixing the plastic packaging bag, it is convenient to place the plastic packaging bag on the surface of the placement plate 41. The plastic packaging bag is located between the two fixing plates 42, and the through hole 48 can limit the movement direction of the moving rod 45.

[0036] In some examples, such as Figure 4As shown, a pull plate 44 is fixedly installed at the upper end of each of the two moving rods 45 above the through hole 48, and a pressure plate 47 is fixedly installed at the lower end of each of the two moving rods 45 below the through hole 48. A spring 46 is provided between the two moving rods 45. The upper end of the spring 46 is fixedly connected to the top of the pressure plate 47, and the upper end of the spring 46 is fixedly connected to the bottom end of the rotating plate 32.

[0037] Pulling one of the pull plates 44 upwards causes the moving rod 45 and pressure plate 47 to move upwards. The spring 46 receives the upward force from the pressure plate 47 and is in a contracted state. Place one side of the plastic packaging bag under the pressure plate 47, release the pull plate 44, and the spring 46 will rebound without force, causing the pressure plate 47 to press and fix one side of the plastic packaging bag. Similarly, press the other pressure plate 47 to press the other side of the plastic packaging bag. At this time, both sides of the plastic packaging bag are pressed and fixed by the pressure plates 47, thus fixing the plastic packaging bag. It can be moved by the drive mechanism 5 and the shifting component 3, and the sealing mechanism 2 can perform the sealing work.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
