Technical Field

[0001] The utility model relates to the technical field of ton bag packaging machines, in particular to a single-side bag hanging mechanism for ton bag packaging machines. Background Art

[0002] Ton bag packaging machine is a large-scale weighing and packaging equipment used for packaging materials in large bags. It integrates electronic weighing, automatic bagging, dust removal and other functions, with high automation, high packaging accuracy, and adjustable packaging speed.

[0003] When ton bag packaging machines are produced in the market now, because they are large-scale weighing and packaging equipment, workers need to climb up a ladder to hang the two hanging corners of the ton bag first, and then go down to the opposite ladder to hang the remaining two hanging corners of the ton bag. The whole process is time-consuming and laborious, and the workers need to climb up and down the ladder many times, which is inconvenient and unsafe.

[0004] Defects and shortcomings of the existing technology:

[0014] The hanging sleeve mechanism comprises a pushing assembly and a bag-removing assembly. The pushing assembly is divided into two groups and connected to the movable hook. The bag-removing assembly is divided into four groups and respectively installed in the fixed hook and the movable hook.

[0015] Through the above technical solution, by connecting the large cylinder lifting mechanism with the lifting connection bracket, the ton bag can be reciprocated and retracted when the equipment is filling, so as to realize the shaping of the ton bag material, and the ton bag can be unfolded with the cooperation of the bag mouth clamping mechanism to facilitate the hanging bag operation. The hanging mechanism can realize that the two sets of bag removal components can be moved to one end of the worker, so as to facilitate the worker to bag without too much displacement.

[0016] As a further improvement of the above solution, a climbing ladder is provided under the equipment frame to assist in the bag hanging operation.

[0017] As a further improvement of the above solution, a connecting frame is symmetrically fixedly connected to the inner side of the lifting connecting bracket, and the top ends of the two groups of connecting frames are connected to the bottom end of the large cylinder lifting mechanism.

The telescopic end of the control cylinder is fixedly connected to a connecting sleeve block, which is hinged at the top of the connecting plate to drive the sleeve rod to release the limit on the ton bag.

[0020] Through the above technical scheme, when using the hanging bag, the ton bag can be put inward under the contact between the spring sheet and the sleeve rod, so that the hanging corner of the ton bag can be hung on the sleeve rod under the elastic action of the spring sheet, and the two are limited when connected, effectively preventing it from falling off.

[0022] Through the above technical solution, the driving force is provided by the pushing cylinder, so that the moving hook can be pushed to move close to the fixed hook under the sliding of the moving wheel and the lifting connection bracket.

[0023] As a further improvement of the above solution, a vertical connecting frame is fixedly connected to the top end of the fixed hook, and the vertical connecting frame is installed on one side of the bottom end of the lifting connecting bracket.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

The fixed hook 4 remains in place, pushing the cylinder 53 piston rod to fully extend, driving the mobile hook 5 to fully extend to the fixed hook 4. The bag mouth clamping mechanism 6 extends, so that the two bag clamping devices are opened, preparing for manual bagging.

[0052] Secondly, the worker takes the ton bag and walks up the ladder 11, opens the ton bag, and manually hangs the two hanging corners on the same side of the ton bag on the fixed hook 4. Then, the control button of the push cylinder 53 is manually triggered to push the piston rod of the cylinder 53 to retract, and at the same time, the two sets of mobile hooks 5 are retracted to the manual operation position, and the two hanging corners on the opposite side of the ton bag are manually hung on the mobile hook 5.

[0053] Finally, the worker puts the mouth of the ton bag into the middle of the two groups of bag clamping devices opened by the bag mouth clamping mechanism 6, presses the clamping button, the cylinder piston rod retracts, the bag mouth clamping mechanism 6 closes and clamps the mouth of the ton bag. Then, the packaging start button is pressed manually, and the piston rods of the two groups of large cylinder lifting mechanisms 3 of the ton bag packaging machine are fully retracted, driving the height of the lifting connection bracket 31 to the highest position, and starting to fill the material. During the filling process of the material, according to the set program, the piston rods of the two groups of large cylinder lifting mechanisms 3 are extended and retracted back and forth many times to achieve the shaping of the ton bag material. After the packaging is completed, the piston rods of the two groups of large cylinder lifting mechanisms 3 are fully extended, the cylinder piston rods of the bag mouth clamping mechanism 6 are extended, the cylinder piston rods of the fixed hook 4 are retracted, and the cylinder piston rods of the mobile hook 5 are retracted, and the connecting sleeve block 44 drives the connecting plate 45 to release the limit of the ton bag with the spring sheet 42, thereby completing the automatic bag removal operation of the entire ton bag.
