Description

Technical Field

[0001] The invention relates to a bag breaking device, in particular to a ton bag automatic bag breaking system, belonging to the technical field of feeding machinery. Background Art

[0002] Ton bags are a kind of flexible transport packaging container, generally made of polyester fibers such as polypropylene and polyethylene. They have the characteristics of simple structure, light weight, foldability, small space occupied by empty space, and low price. Ton bags can be transported in units when equipped with cranes or forklifts. They can be widely used in the packaging of various powdery, granular, and blocky items such as chemicals, building materials, plastics, and mineral products.

[0003] The Chinese patent with the authorization announcement number CN210708275U discloses a ton bag breaking device, including: a rapid lifting device and a cutting knife device, the rapid lifting device is arranged above the cutting knife device, the cutting knife device includes a mounting frame, a plurality of positioning columns with pointed heads and a plurality of blades are fixed on the mounting frame, the mounting frame includes a quadrilateral outer frame and a well-shaped connecting frame, the well-shaped connecting frame is fixedly connected to the outer frame and arranged on the inner side of the outer frame, a plurality of positioning columns are vertically fixed on the well-shaped connecting frame, the blade is fixed obliquely to the mounting frame and intersected with the positioning columns, and each positioning column is arranged to intersect with at least one blade. The ton bag breaking device can prevent the ton bag from shifting during the bag breaking process, and ensure that the ton bag is cut once.

[0004] The above patents and other bag breaking devices in the prior art generally have the following shortcomings:

[0005] 1. The transportation of ton bags before breaking, the breaking process, and the removal of waste bags after breaking all require manual participation, which does not achieve full automation, consumes manpower costs, and is not conducive to the health of operators;

[0006] 2. Before breaking the ton bag, electric hoists are generally used to lift and lower the ton bag and move it horizontally. During the lifting and moving process, the ton bag will inevitably become unstable, sway left and right, and the bag body will shift. The bag body cannot be accurately cut by the knife, and the breaking position of the bag is different, which is easy to cause material residue;

[0007] 3. During the bag breaking process, the cutters are fixed, and the ton bag falls onto the cutter device by its own gravity, cutting the lower end of the ton bag and unloading the material. This method will result in poor bag breaking effect due to insufficient self-weight of the ton bag, slow bag breaking speed and low productivity;

[0008] 4. The residual materials adhering to the ton bag after the bag is broken cannot be processed in time and taken out when the bag is broken, resulting in waste of materials.

[0009] In summary, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to develop an automatic ton bag breaking system to solve the problems of the existing technology. Summary of the invention

[0051] A cross-shaped support arm 67 is fixed to the outer side of the bottom of the sleeve 68, and the outer ends of the cross-shaped support arm 67 are respectively hinged to the lower ends of the knife arms 615 through hinge shafts. Shields 616 are respectively installed at both ends of the hinge shafts.

[0054] The sleeve 68 is sleeved with two telescopic tubes 622 arranged up and down. The telescopic tubes 622 are respectively located at the upper and lower sides of the movable rod 613. The telescopic tubes 622 are used to seal the strip sliding hole 612 to prevent the material from contaminating the bag breaking cylinder 65 in the sleeve 68.

[0055] like Figure 6 As shown, the ton bag beating structure 7 includes two beating rods 71, which are driven to rotate by a driving motor 72, and the rotating beating rods 71 ​​are used to beat off the materials adhered to the inner wall of the waste bag; a dust cover 73 is installed outside the rotating radius of the beating rod 71, and the dust cover 73 can not only play a dust-proof function, but also play a function of protecting the beating rod 71.

[0056] like Figure 1 As shown, the waste bag clamping mechanism 8 includes a rotating arm 81, and a clamping claw 82 is installed at the lower end of the rotating arm 81. The waste bag clamping mechanism 8 is used to clamp the broken waste bag from above the bag breaking mechanism 6.

[0057] The specific working principle of the present invention:

[0058] Conveying process: Multiple conveying chains 21 in the conveying mechanism 2 rotate synchronously to convey the ton bags horizontally. The conveying guide plate 24 guides the ton bags during the conveying process. When the ton bags reach the conveying end of the conveying mechanism 2, the conveying stops.

[0059] Bag grabbing process: first, the second oil cylinder 315 in the horizontal opening component extends, and at the same time, the reset spring 313 presses against the upper end of the horizontal opening gripper 39 to realize the horizontal opening of the horizontal opening gripper 39. The advantage of horizontal opening is that the activity space of the horizontal opening gripper 39 is reduced; then the first oil cylinder 34 in the lifting component extends to drive the horizontal opening component to descend as a whole. When the horizontal opening gripper 39 is located on both sides of the ton bag, the second oil cylinder 315 retracts. During the retraction process, the horizontal opening grippers 39 on both sides move toward each other to clamp the ton bag; then the first oil cylinder 34 retracts, driving the horizontal opening component and the ton bag to rise. During the rising process, the cylinder 35, the linear bearing assembly 36 and the guide rod assembly 33 cooperate to ensure the balance of the rising process of the horizontal opening component to avoid left and right shaking; then the overall gripper mechanism 3 realizes horizontal movement under the action of the gripper pushing mechanism 4, and the ton bag at the end of the horizontal movement is buffered by the ton bag buffer mechanism 5 to avoid strong impact;

[0060] Bag breaking process: First, the bag breaking cylinder 65 extends, and the bag breaking cylinder 65 drives the sliding sleeve 614 to rise through the movable rod 613. During the rising process of the sliding sleeve 614, the knife arm 615 is rotated through the connecting rod 620, and finally the upper end of the knife arm 615 is against the clamping seat 621;

[0061] When the gripper mechanism 3 grabs the ton bag to the top of the bag breaking mechanism 6, the first oil cylinder 34 extends to move the ton bag from top to bottom. During the movement, the cone knife 610 of the bag breaking mechanism 6 first pierces the bottom of the ton bag, and then the ton bag continues to drop. The cutter 617 on the knife arm 615 cuts the four sides of the ton bag. When the bottom of the ton bag drops to the support plate 623, the gripper mechanism 3 releases the ton bag, and the gripper mechanism 3 translates to the initial position; then the bag breaking cylinder 65 retracts to drive the knife arm 615 and the cutter 617 to rotate outward along the hinge point. During the rotation of the cutter 617, the bottom of the ton bag is completely cut to make the material fall. In addition, with the assistance of the vibration motor 625, the speed of bag breaking and material dropping is further accelerated.

[0062] Waste bag clamping and beating process: the broken ton bag is clamped by the clamping claw 82 of the waste bag clamping mechanism 8. During the clamping process, the beating rod 71 of the ton bag beating structure 7 rotates to beat off the residual materials adhering to the inner wall of the waste bag; finally, the rotating arm 81 of the waste bag clamping mechanism 8 rotates to clamp and take out the waste bag.
