DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0020] like Figure 1 As shown, this embodiment provides a packaging bag clamping and transferring device, which is used to clamp the packaging bag 4 and drive the packaging bag 4 to transfer between the unloading track 5 and the vacuum packaging machine 6, including a clamping device 1 and a driving mechanism 2.

[0021] Specifically, Figure 1 and Figure 2 As shown, there are multiple groups of clamping devices 1 in a circular array around a vertically arranged central axis, and the vertical direction refers to the direction perpendicular to the device placement surface; more specifically, in this example, there are six groups of clamping devices 1; each group of clamping devices 1 includes a pair of clamping arms 11 that are spaced apart and have adjustable spacing, and the clamping arms 11 include a fixed plate 12 and a movable plate 13, and the fixed plate 12 has an L-shaped cross-section, including a horizontal portion and a vertical portion, and the lower surface of the horizontal portion is provided with a first track 14 along a direction perpendicular to its own vertical portion, and the movable plate 13 is slidably fitted in the first track 14 and is arranged parallel to the vertical portion of the fixed plate 12, and the fixed plate 12 and the movable plate 13 are used to clamp the packaging bag 4.

[0022] Specifically, Figure 1 , Figure 3 , Figure 4As shown, a plurality of driving mechanisms 2 are arranged in a circular array around the central axis and are all rotatably arranged around the central axis, and the number thereof matches the clamping device 1, that is, a total of six driving mechanisms 2 are arranged; the driving mechanism 2 comprises a lifting frame 21 and a lifting bar 22, the lifting frame 21 is in a rectangular frame shape, and a second track 23 is provided on the inner side of its two vertical sides, the lifting bar 22 is in a rectangular bar shape, and its two ends are respectively slidably matched with the two second tracks 23, and two third tracks 24 are provided in the lifting bar 22 along its own length direction, and the two third tracks 24 are symmetrically arranged at the two ends of the lifting bar 22, and the third tracks 24 pass through the front side and the rear side of the lifting bar 22, and a slider 25 is slidably matched in the third track 24, and the slider 25 is connected to a driving rod 26, and the two driving rods 26 respectively pass through the front side of the lifting bar 22 and are connected to the two fixed plates 12 of the same group of clamping devices 1.

[0023] During operation, in this example, since the equipment has six groups of clamping devices 1 and six groups of driving mechanisms 2, the equipment can be used in conjunction with two workstations. One workstation includes three working conditions, namely, fixing the packaging bag 4, cooperating with the unloading track 5 to receive the material, and cooperating with the vacuum packaging machine 6 for packaging.

[0024] When fixing, move the movable plate 13 of the corresponding clamping device 1 to increase the distance between the movable plate 13 and the fixed plate 12, and use a mechanical device or manually to extend the two opening edges of the packaging bag 4 between the movable plate 13 and the vertical parts of the fixed plate 12 on different clamping arms 11, and reduce the distance between the vertical parts of the movable plate 13 and the fixed plate 12, so that the movable plate 13 and the vertical parts of the fixed plate 12 clamp the opening edge of the packaging bag 4, thereby completing the fixation of the packaging bag 4.

[0025] When receiving materials, it is necessary to rotate the corresponding driving mechanism 2 to move the fixed packaging bag 4 to the bottom of the unloading track 5. At this time, the two sliders 25 in the lifting bar 22 in the corresponding driving mechanism 2 are moved to the two ends of the lifting bar 22 respectively, that is, the distance between the two sliders 25 is widened. The slider 25 increases the distance between the corresponding two clamping arms 11 through the driving rod 26, thereby enlarging the distance between the opening edges of the packaging bag 4, making the opening of the packaging bag 4 larger. At this time, the packaging bag 4 can be received from the unloading track 5.

[0026] During packaging, the corresponding driving mechanism 2 needs to be rotated to move the packaging bag 4 with the material received to the top of the vacuum packaging machine 6. At this time, the slider 25 is moved to shorten the distance between the two sliders 25, and then the distance between the two clamping arms 11 is reduced through the driving rod 26, and the distance between the opening edges of the packaging bag 4 is reduced. The lifting bar 22 is moved downward to allow the packaging bag 4 to enter the vacuum packaging machine 6. After the packaging bag 4 is completely entered, the distance between the vertical parts of the movable plate 13 and the fixed plate 12 is increased, and the packaging bag 4 is separated from the clamping device 1 and enters the vacuum packaging machine 6 to complete the packaging; the corresponding driving mechanism 2 is rotated again to allow the clamping device 1 to enter the next station.

[0027] Preferably, Figure 1~Figure 4 As shown, a first electric screw 15 is provided in the first track 14 along its own length direction, and the movable plate 13 is matched with the first electric screw 15. The first electric screw 15 is used to drive the movable plate 13 to move in the first track 14, thereby adjusting the distance between the movable plate 13 and the vertical part of the fixed plate 12; a second electric screw 27 is vertically provided in the lifting frame 21, and the lifting bar 22 is matched with the second electric screw 27. The second electric screw 27 is used to drive the lifting bar 22 to move in the second track 23, thereby adjusting the height of the clamping device 1; a third electric screw 28 is provided along the third track 24 along its own length direction, and the slider 25 is matched with the third electric screw 28 along its own length direction. The third electric screw 28 is used to drive the slider 25 to move in the third track 24, thereby adjusting the distance between the clamping arms 11 in the same group of clamping devices 1.

[0028] Preferably, Figure 1 , Figure 3 , Figure 4 As shown, the device also includes a rotating table 3, which is coaxially arranged with the central axis, and a first turntable 31 is coaxially rotatably connected to the upper surface thereof. Further preferably, a rotating mechanism is provided in the rotating table 3, and the rotating mechanism can adopt a rotating drive mechanical device such as a rotating cylinder and a rotating motor. The driving shaft of the rotating mechanism is coaxially connected to the first turntable 31 to drive the first turntable 31 to rotate; the bottom of the lifting frame 21 is arranged on the first turntable 31, and the top of the lifting frame 21 is arranged on the second turntable 32.
