DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0029] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 A schematic structural diagram of a preferred embodiment of the automatic turnover mechanism for a packaging machine provided by the present invention; Figure 2 for Figure 1 An enlarged schematic diagram of part A is shown; Figure 3 for Figure 1 The structural schematic diagram of the lifting device shown; Figure 4 for Figure 1 A side view of the flipping mechanism of the packaging machine shown; Figure 5 for Figure 1 The structural schematic diagram of the flipping mechanism of the packaging machine is shown. An automatic flipping mechanism of the packaging machine comprises a workbench 1;

[0030] A conveying device 2, wherein the conveying device 2 is fixedly mounted on the surface of the workbench 1;

[0031] The conveying device 2 includes two rotating drums, the surfaces of which are sleeved with conveyor belts, fixing rods are fixedly installed on both sides of the two rotating drums, and a third motor is fixedly installed on one side of one of the rotating drums.

[0033] The support frame 3 is in the shape of a letter U, and the support frame 3 is placed on both sides of the conveying device 2 .

[0034] The flipping device 4 is fixedly installed in the middle position of the surface of the support frame 3, and the flipping device 4 includes a first motor 41. One end of the output shaft of the first motor 41 is fixedly connected to a rotating disk 42 through a coupling, and one side of the rotating disk 42 is rotatably connected to a connecting plate 43 through a rotating shaft. An installation cavity 44 is provided inside the support frame 3, and slide grooves 45 are provided on both sides of the inner wall of the installation cavity 44. Slide blocks 46 are slidably connected inside the two slide grooves 45. A fixed plate 47 is fixedly connected between the two slide blocks 46, and a baffle 48 is fixedly connected to one side of the fixed plate 47.

[0035] The first motor 41 is threadedly connected to one side of the surface of the support frame 3 through a threaded bolt, and when the first motor 41 rotates, it drives the rotating disk 42 to rotate one hundred and eighty degrees each time. After each rotation of the rotating disk 42 one hundred and eighty degrees, the first motor 41 stops working, and the baffle 48 moves to the outside of the installation cavity 44. When the rotating disk 42 rotates the remaining one hundred and eighty degrees again, it drives the baffle 48 to move to the inside of the installation cavity 44. One end of the connecting plate 43 is rotatably connected to the fixed plate 47 through a rotating member, and one side of the connecting plate 43 is fixedly connected to the center of the fixed plate 47.

[0036] A carton 5 is arranged on the surface of the conveying device 2 , and a partition plate 6 is fixedly installed on the surface of the conveying device 2 .

[0037] A plurality of elongated partitions 6 are fixedly mounted on the conveyor belt of the conveyor device 2.

[0038] Hydraulic rods 7 are fixedly mounted on both sides of the inner wall of the support frame 3 , and limiting plates 8 are fixedly mounted on one end of the two hydraulic rods 7 .

[0039] The two hydraulic rods 7 are also threadedly connected to the inner wall of the support frame 3 via threaded bolts.

[0040] A lifting device 9 is provided at the bottom of the inner wall of the workbench 1 , and the lifting device 9 includes a second motor 91 , and one end of the output shaft of the second motor 91 is fixedly connected to a rotating rod 92 through a coupling.

[0041] The second motor 91 is also threadedly connected and fixed to the bottom of the inner wall of the workbench 1 by means of threaded bolts.

[0042] The first pulleys 93 are sleeved on both sides of the surface of the rotating rod 92, and a rotating shaft 94 is set at the bottom of the inner wall of the workbench 1 and on both sides of the second motor 91. The surface of the rotating shaft 94 is fixedly installed with a sleeve 95, and the inside of the two sleeves 95 is provided with a threaded rod 96.

[0043] The two sleeves 95 have different lengths, and one end of the two lifting tubes 97 respectively penetrates the top two sides of the inner wall of the workbench 1 and extends to the outside of the workbench 1 and is fixedly connected to the two sides of the bottom of the support frame 3.

[0044] The surfaces of the two threaded rods 96 are sleeved with lifting tubes 97 , the surfaces of the two sleeves 95 are sleeved with second pulleys 98 , and the two first pulleys 93 and the two second pulleys 98 are connected by belts 99 .

[0045] A door 10 is provided on the front of the workbench 1 .

[0046] The box door 10 opened on the front of the workbench 1 is a double-opening door, and one side of the box door 10 is connected to the two sides of the workbench 1 through a hinge.

[0047] The working principle of the automatic flipping mechanism of the packaging machine provided by the present invention is as follows:

[0048] During operation, first, the second motor 91 is started to rotate. When the second motor 91 rotates, it drives the rotating rod 92 to rotate. When the rotating rod 92 rotates, it drives the two first pulleys 93 to rotate. When the two pulleys 93 rotate, the two second pulleys 98 are driven to rotate through the two belts 99. When the two second pulleys 98 rotate, the two sleeves 95 are driven to rotate through the rotating shaft 94 on both sides of the bottom of the inner wall of the workbench 1. When the two sleeves 95 rotate, they drive the two internal threaded rods 96 to rotate. When the two threaded rods 96 rotate, they drive the two lifting tubes 97 to move toward the top of the inner wall of the workbench 1. When the two lifting tubes 97 rise, they push the support frame 3 on the surface of the workbench 1 to move upward.

[0049] When the lifting device 9 pushes the support frame 3 to move to the appropriate position, the second motor 91 is turned off, and then the operator places the carton 5 on the surface of the conveying device 2. After the carton 5 is placed, the hydraulic rods 7 on both sides of the inner wall of the support frame 3 are started to drive the limit plates 8 to move to one side of the carton 5. When the two hydraulic rods 7 drive the two limit plates 8 to contact the carton 5, the conveying device 2 is started again. When the conveying device 2 rotates, it drives the carton to move to the inside of the support frame 3. When the carton moves to the bottom of the support frame 3, the first motor 41 is started again. When the first motor 41 rotates, it drives the rotating disk 42 to rotate.

[0050] When the rotating disk 42 rotates, the connecting plate 43 is driven to move through the rotating shaft. When the connecting plate 43 moves, it pushes the fixed plate 47 to move inside the installation cavity 44. When the fixed plate 47 moves, it drives the two sliders 46 to move inside the slide grooves 45 on both sides of the inner wall of the installation cavity 44. When the fixed plate 47 moves, it drives the baffle 48 to move. When the baffle 48 moves to the outside of the installation cavity 44 and contacts the carton 5, the first motor 41 is turned off. At this time, the first motor 41 drives the connecting plate 43 to rotate halfway. When the conveying device 2 drives the carton 5 to continue to move to one side of the baffle 48, the baffle 48 and the partition 6 on the surface of the conveying device 2 are used to rotate the carton 5 to the other side. When the carton 5 rotates to the other side and is marked, the conveying device 2 continues to push the carton 5 to move.

[0051] When the carton 5 continues to move, the first motor 41 is started again to drive the connecting plate 43 to move through the rotating disk 42. When the connecting plate 43 moves, it drives the fixed plate 47 to move toward the top of the inner wall of the installation cavity 44. When the fixed plate 47 moves, it drives the two sliders 46 to move inside the slide groove 45 on both sides of the inner wall of the installation cavity 44 toward the top of the inner wall of the slide groove 45. When the fixed plate 47 moves, it drives the baffle 48 to move into the installation cavity 44. After the baffle 48 moves to the inside of the installation cavity 44, the conveying device 2 drives the carton 5 to move to the next production line.

[0052] Compared with the related art, the automatic flipping mechanism of the packaging machine provided by the present invention has the following beneficial effects:

[0053] The flipping device 4 can be used to block and flip objects. The two slide grooves 45 and the two sliders 46 can be used together to fix the baffle 48 to prevent the baffle 48 from being unable to block objects when working. The first motor 41, the rotating disk 42 and the connecting plate 43 can make the baffle 48 adapt to flipping objects of various sizes.
