Description

Technical Field

[0001] The utility model relates to the technical field of air-extracting powder packaging machines, in particular to an air-extracting powder packaging device. Background Technique

[0002] An air-extracting powder packaging machine is a professional device for packaging powdery materials. Its main function is to quantitatively fill powdery materials into packaging bags and perform air-extracting treatment on the packaging bags during the packaging process to extend the shelf life of the powdery materials, reduce the packaging volume at the same time, and facilitate storage and transportation.

[0003] In the existing air-extracting powder packaging machines, a conveyor belt is arranged below the feeding pipe to output packaging bags. When operating, the operator usually puts the packaging bag on the feeding pipe, and then the clamp on the feeding pipe clamps the packaging bag to facilitate air extraction. Therefore, both the clamp and the feeding pipe have to bear gravity every time they fall. After a long time, the number of times the clamp is damaged is relatively high. When using shorter packaging bags, the height of the conveyor belt needs to be adjusted, and when adjusting the height of the conveyor belt, the entire long machine needs to be lifted, which is very troublesome. To solve the above problems, we propose this air-extracting powder packaging device. Content of the Utility Model

[0004] The main purpose of the utility model is to provide an air-extracting powder packaging device, which can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

DETAILED DESCRIPTION OF THE INVENTION

[0022] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] As Figures 1-5 shown, an air-extracting powder packaging device includes a packaging machine body 1, a first mounting frame 2 and a second mounting frame 8. A second conveyor belt 9 is arranged in the second mounting frame 8. A conveying mechanism for conveying packaging bags is arranged on the first mounting frame 2. The conveying mechanism includes a cross plate 3 slidably connected to the inner wall of the first mounting frame 2. The upper end of the cross plate 3 is connected with a mounting frame 5 through a driving mechanism. A driving component is arranged between the mounting frame 6 and the side wall of the second mounting frame 8. The driving component includes a servo motor, etc. A first conveyor belt 6 is arranged in the mounting frame 5. A motor 4 is fixedly connected to the bottom of the inner part of the first mounting frame 2. The output shaft of the motor 4 is fixedly connected with a threaded rod. A limiting rod 7 is arranged at the top of the inner part of the first mounting frame 2. A plurality of support legs 11 are arranged at the lower end of the second mounting frame 8.

[0024] The driving mechanism includes a plurality of hydraulic cylinders 10 fixedly connected to the upper end of the cross plate 3. The upper ends of the hydraulic cylinders 10 are fixedly connected with the lower end of the mounting frame 5.

[0025] In the present utility model, a fixed frame 12 is arranged on the side wall of the support leg 11. The fixed frame 12 is fixedly connected with the second mounting frame 8. The support leg 11 is not fixedly connected to the lower end of the second mounting frame 8. A second bolt 17 is arranged on the side wall of the support leg 11. A nut is arranged on the side wall of the second bolt 17, so that the height of the second mounting frame 8 can be adjusted, which is convenient for conveying packaging bags with a large length difference.

[0026] In the present utility model, a first connecting piece 13 is arranged on the side walls of a plurality of fixed frames 12, and a second connecting piece 19 is arranged on the side walls of a plurality of support legs 11, so that the overall strength of the second mounting frame 8 is higher.

[0027] In the present utility model, fixing plates 15 are fixedly connected to both side walls of the first mounting frame 2. A vertical rod 18 penetrates through the upper end of the fixing plate 15. A universal wheel 14 is arranged at the lower end of the vertical rod 18. Two first bolts 16 are arranged on the side wall of the fixing plate 15, so that the first mounting frame 2 has a movable function and is convenient for handling.

[0028] In the present utility model, the cross section of the vertical rod 18 is rectangular, which can prevent the vertical rod 18 from rotating randomly when moving. The universal wheel 14 is a locking universal wheel, which can enable the first mounting frame 2 to stop at any time.

[0029] It should be noted that the utility model is a vacuum powder packaging device. The user puts the packaging bag on the unloading pipe of the packaging machine body 1, the motor 4 is started, the output shaft of the motor 4 drives the threaded rod to rotate, the cross plate 3 moves upward, the first conveyor belt 6 moves upward to receive the packaging bag, the packaging machine body 1 discharges and evacuates, then the output shaft of the motor 4 is reversed, the packaging bag moves down to a height slightly higher than the second conveyor belt 9, the driving components of the first conveyor belt 6 and the second conveyor belt 9 are started, the packaging bag falls from the first conveyor belt 6 to the second conveyor belt 9, and the second conveyor belt 9 continues to output the packaging bag. When the enterprise uses packaging bags of different lengths to package powder, it is not necessary to adjust the height of the entire second conveyor belt 9, thereby eliminating the trouble of back and forth adjustment. At the same time, the first conveyor belt 6 can receive the packaging bag, reducing the pressure on the clamp of the packaging machine body 1 and increasing its service life.

[0030] In addition, for smaller packaging bags, multiple nuts can be loosened, the second mounting frame 8 can be lifted, the supporting legs 11 can be lowered, and the nuts can be tightened to raise the height of the second conveyor belt 9, making it easier for the equipment to transport smaller packaging bags, thereby expanding the scope of application of the device.
