[0002] Ton bags, also known as flexible container bags and space bags, have the advantages of large capacity, light weight, and easy loading and unloading. They are often used to transport bulk powder materials. For example, the positive and negative electrode materials in the lithium battery industry are often packaged in ton bags. These ton bags usually have a bag mouth and a handle. Ton bag packaging machine is a large-scale weighing packaging equipment used for ton bag packaging materials. It is a multi-purpose packaging machine that integrates electronic weighing, automatic bagging, and dust removal.

However, the operation is complicated, resulting in longer filling time and lower efficiency. Therefore, an adaptive mechanism for ton packaging bags of multiple specifications is provided to solve the problems raised in the above background technology. Utility Model Content

[0021] See also Figures 1 to 4 : An adaptive mechanism for bags of various specifications for ton packaging, comprising a support platform 8, a pneumatic box 2 is installed on the support platform 8, a double-control solenoid valve 1 with a center seal is installed inside the pneumatic box 2, a squatting bag cylinder 3 is arranged on one side of the pneumatic box 2, a magnetic switch 1 4 and a magnetic switch 2 5 are respectively installed on the squatting bag cylinder 3, a feeding barrel 6 is arranged between the squatting bag cylinders 3, a bag clamping and bag holding machine 9 is installed at the output end of the squatting bag cylinder 3, and a loading structure 12 is arranged on the lower side of the bag clamping and bag holding machine 9.

[0022] When in use, the bag clamping and bag holding machine 9 is first used to clamp the loading structure 12 to fix the position of the loading structure 12 so that the loading structure 12 is located at the lower side of the feeding tube 6, and then the loading structure 12 is filled through the feeding tube 6.

[0023] Furthermore, when the large-ton bag 11 in the loading structure 12 is filled, the double-control belt center-sealing solenoid valve 1 controls the output end of the squat bag cylinder 3 to move to a specified position, so that the output end of the squat bag cylinder 3 is in the middle position, and then the magnetic switch 4 feeds back a signal to the double-control belt center-sealing solenoid valve 1, so that the bag clamping and bag supporting machine 9 stops moving, and the large-ton bag 11 is unhooked to complete the filling.

[0024] Furthermore, when the small-ton bags 10 in the loading structure 12 are filled, the double-control belt center-sealing solenoid valve 1 controls the output end of the squat bag cylinder 3 to move to a specified position, so that the output end of the squat bag cylinder 3 is at a low position, and then the magnetic switch 2 5 feeds back a signal to the double-control belt center-sealing solenoid valve 1, so that the bag clamping and bag supporting machine 9 stops moving, and the small-ton bag 10 is unhooked to complete the filling.

[0025] Preferably, a weighing frame 7 is provided at the connection between the squat bag cylinder 3 and the support platform 8, and the squat bag cylinder 3 is installed on the weighing frame 7.

[0026] Among them, the weighing frame 7 weighs the loading structure 12 clamped under the squat bag cylinder 3 in real time. When the weight inside the loading structure 12 reaches a preset value, the feeding barrel 6 stops feeding the loading structure 12.

[0027] Preferably, the feed cylinder 6 is fixed to and connected with the support platform 8 , and the feed cylinder 6 passes through the weighing frame 7 .

[0028] The feed barrel 6 is not connected to the weighing frame 7 , so that the material inside the feed barrel 6 can be prevented from interfering with the weighing frame 7 , and will not affect the weighing result of the charging structure 12 by the weighing frame 7 .

[0029] Preferably, the bag clamping and bag holding machine 9 is electrically connected to the double-control belt center-sealing solenoid valve 1 .

[0030] The double-control-belt center-sealing electromagnetic valve 1 can be used to control the bag clamping and bag-supporting machine 9 to clamp or release the loading structure 12 .

[0031] Preferably, the loading structure 12 includes small-ton bags 10 and large-ton bags 11 , and the bag clamping and bag-supporting machine 9 supports and clamps the small-ton bags 10 and the large-ton bags 11 .

[0032] Among them, Figure 3 and 4 As shown, the bag clamping and bag holding machine 9 clamps or releases the loading structure 12, and the difference between the small-ton bags 10 and the large-ton bags 11 makes the output end telescopic lengths of the squatting bag cylinder 3 different, so that the small-ton bags 10 and the large-ton bags 11 are transported to the same height, so that the heights of the small-ton bags 10 and the large-ton bags 11 remain consistent after unhooking.

[0033] Preferably, a bottom lining plate 13 is fixedly connected to the bottom side of the support platform 8, a placement cavity 131 is provided inside the bottom lining plate 13, a drive motor 134 is installed inside the placement cavity 131, an eccentric wheel 136 is fixedly connected to the output end of the drive motor 134, an elastic belt 133 is rotatably connected to the eccentric wheel 136, a placement plate 132 is fixedly connected to the upper side of the bottom lining plate 13 via a reset spring rod 135, and the placement plate 132 is hinged to the elastic belt 133.

[0034] Among them, when the squat bag cylinder 3 moves the small-ton bag 10 or the large-ton bag 11 downward, it will contact the placement plate 132 (not unhooked) on the bottom lining plate 13, and then start the drive motor 134 to drive the eccentric wheel 136 to rotate. When the eccentric wheel 136 rotates, it will pull the placement plate 132 back and forth through the elastic belt 133, causing the placement plate 132 to shake up and down, thereby driving the small-ton bag 10 or the large-ton bag 11 on the placement plate 132 to shake, preventing air from accumulating in the material inside the small-ton bag 10 or the large-ton bag 11, thereby facilitating the packaging of the small-ton bag 10 or the large-ton bag 11.

[0035] Working principle: when in use, first clamp the loading structure 12 through the bag clamping and bag holding machine 9, fix the position of the loading structure 12, so that the loading structure 12 is located at the lower side of the feeding tube 6, and then fill the loading structure 12 through the feeding tube 6; wherein when the large-ton bag 11 is filled with bags, the double-control belt center-sealing solenoid valve 1 controls the output end of the bag squatting cylinder 3 to move to the specified position, so that the output end of the bag squatting cylinder 3 is in the middle position, and then the magnetic switch 14 feedbacks the signal to the double-control belt center-sealing solenoid valve 1, so that the bag clamping and bag holding machine 9 stops, and the large-ton bag 11 is unhooked to complete the filling; when the small-ton bag 10 is filled with bags, the double-control belt center-sealing solenoid valve 1 controls the output end of the bag squatting cylinder 3 to move to the specified position, so that the output end of the bag squatting cylinder 3 is in the low position, and then the magnetic switch 25 feedbacks the signal to the double-control belt center-sealing solenoid valve 1, so that the bag clamping and bag holding machine 9 stops, and the small-ton bag 10 is filled. Unhooking to complete filling; in the above structure, the squat bag cylinder 3 is controlled by the double-control belt middle sealing solenoid valve 1, so that the output end of the squat bag cylinder 3 has different telescopic lengths, so that the squat bag cylinder 3 transports the small ton bag 10 and the large ton bag 11 to the same height, so that the height of the small ton bag 10 and the large ton bag 11 is consistent after unhooking; when the squat bag cylinder 3 moves the small ton bag 10 or the large ton bag 11 downward, it will contact the placement plate 132 on the bottom liner 13 ( When the eccentric wheel 136 rotates, it pulls the placement plate 132 back and forth through the elastic belt 133, causing the placement plate 132 to shake up and down, thereby driving the small-ton bag 10 or the large-ton bag 11 on the placement plate 132 to shake, preventing the material inside the small-ton bag 10 or the large-ton bag 11 from accumulating air, thereby facilitating the packaging of the small-ton bag 10 or the large-ton bag 11.
