Description

Technical Field

[0001] The utility model relates to the field of vacuum packaging machines, in particular to a double-bag vacuum machine. Background Art

[0002] The double-bag vacuum machine is mainly used for bag-in-bag packaging. Its structure mainly includes a turntable with vacuum disks evenly distributed around the circumference. The vacuum disk is evacuated at one of the resting stations through a gas distributor during the turntable process. The gas distributor is connected to a vacuum pump. With the improvement of production efficiency, the vacuum extraction time of the original resting stations has been greatly shortened, resulting in insufficient vacuum extraction. At the same time, the turntable is rotatably connected to the support through bearings. The original bearings are randomly set, resulting in uneven force on the bearings and difficulty in bearing load. The wear of the bearings increases, which greatly affects the service life of the bearings. At the same time, the opening and closing of the vacuum disk is achieved through a complex cam contact opening and closing, which has a complex structure and is inconvenient to install. These factors greatly affect the service life and structural rationality of the double-bag vacuum machine. Utility Model Content

[0012] The present invention is specifically described below through embodiments, which are only used to further illustrate the present invention and should not be construed as limiting the protection scope of the present invention.

[0013] like Figure 1 — Figure 4As shown, this embodiment discloses a double-bag vacuum machine, including a frame 1, a rotating shaft, a rotating disk 2 and a column 3. The rotating disk 2 is installed in the rotating disk 2 column 3 through a bearing. The rotating shaft and the rotating disk 2 are connected through a gear set transmission connection. The rotating shaft is driven by a motor. The rotating disk 2 is connected to the rotating shaft. A vacuum disk 4 uniformly distributed around the circumference is installed on the edge of the rotating disk 2. The vacuum disk 4 includes a fixed disk 41 and a movable disk 42. The fixed disk 41 is connected to the rotating disk 2. The movable disk 42 is rotatably installed on the fixed disk 41 through a rotating shaft. The movable disk 42 is rotatably connected to the fixed disk 41 through a lever arm 43. One end of the lever arm 43 is movably connected to the movable disk 42 through a connecting plate 44. The other end of the lever arm 43 is connected to a pull rod 45. A swing arm 46 that can rotate left and right is installed on the fixed disk 41. The rotating end of the swing arm 46 is movably connected to the pull rod 45. A roller 47 is installed on the swing arm 46. An opening and closing guide rail (not shown in the figure) is provided corresponding to the roller 47. The guide rail is in an arc shape. After the roller 47 rolls onto the opening and closing guide rail, the pull rod 45 is pulled to drive the movable disk 42 to rotate and open the vacuum disk. After the roller 47 rolls off the closing guide rail, the movable disk returns to its original position due to gravity and closes the vacuum disk. A first deep groove bearing 5, a plane bearing 6 and a second deep groove bearing 7 are arranged from top to bottom between the column 3 and the turntable 2. A gas distributor 8 is also installed on the column 3. The gas distributor 8 includes a gas distributor bottom plate 81, a gas distributor middle plate 82 and a gas distributor upper plate 83. The gas distributor middle plate 82 is provided with more than two consecutive workstation adsorption grooves 821. The figure shows three workstation adsorption grooves 821, that is, the vacuum disk 4 is continuously evacuated at three workstations, which improves the quality of vacuuming. The gas distributor upper plate 83 is connected to the vacuum disk 4 pipeline and rotates with the vacuum disk 4. The gas distributor bottom plate 81 is connected to the vacuum pump. When the air vent on the gas distributor upper plate 83 rotates to the position of the workstation adsorption groove 821, the vacuum disk 4 realizes the vacuuming operation. In this way, the technical effects of balanced bearing, sufficient vacuuming and reasonable and simple opening and closing structure of the vacuum disk 4 are achieved.

[0014] The rotating disk 2 is connected with a frame 9, and the frame 9 is connected with the gas separation upper plate 83 through a straight rod. In this way, the rotating disk 2 drives the gas separation upper plate 83 to rotate during rotation.

[0015] By adopting the above technical scheme, the deep groove bearing has the characteristics of small resistance and high rotation speed, while the plane bearing 6 has the characteristics of good axial support. The first deep groove bearing 5, the plane bearing 6 and the second deep groove bearing 7 are arranged between the column 3 and the turntable 2 from top to bottom. This can ensure the balance of load-bearing while ensuring the smoothness of rotation of the package turntable 2. The structure is more reasonable and the service life of the bearing is greatly improved. At the same time, the opening and closing of the vacuum disk 4, that is, the rotation of the movable disk 42 can be opened and closed by means of rollers 47 and opening and closing guide rails. This structure is relatively simple and reasonable, with high transmission efficiency and more convenient installation and operation. More than two consecutive workstation adsorption grooves 821 are provided on the gas distribution center disk 82, which can effectively improve the vacuuming time, so that the vacuum disk 4 has sufficient vacuuming time during the high-speed operation of the turntable 2, so that the vacuuming effect of the vacuum disk 4 is better, thus achieving the technical effects of balanced bearing load, sufficient vacuuming and reasonable and simple opening and closing structure of the vacuum disk 4.
