[0002] ‌‌Polypropylene monofilament filter material is a filter material woven from polypropylene (PP) monofilament. It has excellent corrosion resistance, wear resistance and high temperature resistance. Its monofilament structure means that each fiber is independent. This design reduces the crossover points between fibers and reduces the roughness of the filter cloth surface, thereby improving the filtration efficiency and cleaning effect‌.

[0003] At present, for the sake of cost, the vacuum packaging of polypropylene monofilament filter materials is generally done by manually putting the filter materials into packaging bags, then using a vacuum pump to extract the air in the package of the bagged polypropylene monofilament filter materials, and then using a sealing device to seal the mouth of the packaging bag to complete the vacuum packaging of the polypropylene monofilament filter materials. After sealing, the packaged polypropylene monofilament filter materials are removed for collection, and the operation is repeated to complete the subsequent vacuum packaging of the polypropylene monofilament filter materials, and finally manually transported. This vacuum packaging method has more manual intervention and low efficiency, and manual operation is prone to errors that cause individual packages to leak, resulting in a decrease in the quality of the vacuum packaging, affecting the production efficiency of the entire process of vacuum packaging of polypropylene monofilament filter materials.

The top of box body 1 is fixedly connected with two packaging slots 12, and the packaging slots 12 work alternately to make full use of the time gap between loading and unloading, so as to improve the packaging efficiency. The outer wall of the box body 1 on one side away from the side support block 11 is integrally fixedly connected with a control panel 14, and the bottom end of box body 1 is detachably connected with universal wheel 13, and the mobility of box body 1 is improved by universal wheel 13, so that the packaging device can be conveniently moved to a suitable place for installation and placement; The sealing switching mechanism 2 includes a driving shaft 21 and two driven shafts 23. The outer wall of the driving shaft 21 is coaxially fixedly connected with a driving gear a22. The outer walls of the two driven shafts 23 are coaxially fixedly connected with driven gears a24 meshing with the driving gear a22. A rotating plate 25 is coaxially fixedly connected to the driven shaft 23. The other end of the rotating plate 25 is rotatably connected with a vacuum cover 26. The driving gear a22 is driven to rotate by the driving shaft 21. The driven shaft 23 is driven to rotate by meshing the driving gear a22 with the driven gear a24. The rotating plate 25 rotates synchronously with the driven shaft 23 to complete the back and forth switching of the vacuum cover 26, and switches with different packaging slots 12 to form a closed packaging space; The picking mechanism 4 is provided with two picking mechanisms 4, and both are arranged on the top side of the side support block 11. The two picking mechanisms 4 are symmetrical about the center of the driving shaft 21, so that the loading and unloading in the two packaging slots 12 are synchronously performed in opposite directions, that is, when one packaging slot 12 completes the loading operation, the other packaging slot 12 completes the material removal operation. A linkage mechanism 3 is provided between the driving shaft 21 and the picking mechanism 4. The picking mechanism 4 includes a support plate 41, a loading plate 42 and a transmission assembly 45. The support plate 41 is transmission-connected to the linkage mechanism 3, the loading plate 42 is slidably connected to the support plate 41, and the loading plate 42 is connected to the support plate 41. Slide plates 421 are fixedly connected on both sides, a hydraulic rod 43 is fixedly connected to the inner wall of the support plate 41, a movable tooth plate 44 is fixedly connected to the output end of the hydraulic rod 43, a through groove for accommodating the sliding of the movable tooth plate 44 is opened on the slide plate 421, a protrusion 441 that cannot pass through the through groove is fixedly connected to the side of the movable tooth plate 44 away from the tooth surface, a vertical tooth plate 46 is slidably connected to the outer wall of the support plate 41, a transmission assembly 45 is arranged between the vertical tooth plate 46 and the movable tooth plate 44 to link the loading plate 42 and the vertical tooth plate 46, and a material taking plate 47 is fixedly connected to the bottom end of the vertical tooth plate 46; The vacuum pump 5 is connected to the packaging tank 12 through a pipeline. The air in the package is evacuated by the vacuum pump 5 to ensure a vacuum environment of the package.

[0032] Specifically, before use, the vacuum cover 26 is closed with one packaging slot 12, and the bagged polypropylene monofilament filter material on one side of the unclosed packaging slot 12 is first placed on the loading plate 42, and a driving motor is installed at one end of the driving shaft 21. The driving shaft 21 rotates to drive the driving gear a22 to rotate, and the driving gear a22 is meshed with the driven gear a24 to drive the driven shaft 23 to rotate. The rotation of the driven shaft 23 drives the rotating plate 25 to rotate, and the rotating plate 25 drives the vacuum cover 26 to rotate and gradually close with the other packaging slot 12. During the rotation of the vacuum cover 26, the linkage mechanism 3 works to drive the two supporting plates 41 to rotate synchronously. When the supporting plate 41 containing the polypropylene monofilament filter material rotates to the top side of the packaging slot 12, specifically when the opening side of the packaging bag is parallel to the long side of the packaging slot 12, the vacuum cover 26 stops rotating, and the hydraulic rod 43 is started to control the loading plate 42 to retract, so that the bagged polypropylene monofilament filter material falls into the packaging slot 12 and is Before recycling, under the action of the transmission assembly 45, the vertical tooth plate 46 is dropped in advance, and the sealed polypropylene monofilament filter material is lifted and moved to the take-up plate 47 by the take-up plate 47 during the rotation of the support plate 41. After the bagged polypropylene monofilament filter material falls, the vacuum cover 26 continues to rotate, and the carrier plate 42 returns, driving the vertical tooth plate 46 to move upward to ensure that the support plate 41 does not interfere with the rotation of the vacuum cover 26. It should be noted that the movement states of the carrier plates 42 on both sides are opposite. When the vacuum cover 26 rotates and closes the packaging groove 12, the vacuum pump 5 sucks the package into a vacuum, and the heat sealing plate 261 contacts the support plate 121 to seal the bagged polypropylene monofilament filter material. Finally, the sealed polypropylene monofilament filter material can be taken from the take-up plate 47. In order to further improve the efficiency, two conveyor belts can be added, which are flush with the support plate 41 respectively. It should be noted that the conveyor belt is a prior art and is not described in detail, and is not shown in the figure.
