DETAILED DESCRIPTION

[0026] The present invention will be further described below with reference to specific drawings.

[0027] The ton bag 100 comprises a bag body 110 and a bag mouth 120 connected to the bag body 110 . An end of the bag body 110 away from the bag mouth 120 is provided with a plurality of slings 111 distributed in a one-to-one correspondence at each corner position.

[0028] See also Figure 1The present invention provides a ton bag 100 unpacking device for unpacking ton bags 100. The device comprises a frame 200, a suspension mechanism 300 disposed within the frame 200, a flapping mechanism 400 and a discharge mechanism 500 disposed within the frame 200, and a material receiving mechanism disposed below the discharge mechanism 500. The suspension mechanism 300 is capable of entering and exiting the frame 200 and includes a hook 340 for suspending the ton bag 100. The hook 340 is capable of reciprocating along the height direction of the frame 200. The discharge mechanism 500 is located below the flapping mechanism 400. The discharge mechanism 500 has an inlet channel at its top and an outlet channel at its opposite end. When the bag spout 120 enters the inlet channel, the flapping mechanism 400 is capable of flapping the bag body 110. The outlet channel is connected to a locking mechanism 600 for controlling the opening and closing of the outlet channel. After the suspension mechanism 300 is moved out of the frame 200, the hook 340 descends and connects to the ton bag 100. After the ton bag 100 is suspended, the suspension mechanism 300 drives the ton bag 100 into the frame 200, extends the bag mouth 120 into the inlet channel, and then unties the cable tie. The molding sand in the bag body 110 is transported to the lower feeding mechanism 500. Opening the locking mechanism 600 can transport the material to the material receiving mechanism, and the material can be received from the position of the material receiving mechanism for use; if the material agglomerates and has poor fluidity, the flapping mechanism 400 can be started to flap the material outside the bag body 110 to enhance the smoothness of the flow; the locking mechanism 600 can be opened or closed according to actual needs, and the material retrieval process is easy to control. The unpacking device can be used to unpack the ton bag 100, which can realize mechanized operation. In the process of unpacking, the flapping mechanism 400 can be started to flap the ton bag 100. The fluidity of the material in the ton bag 100 is enhanced, making the unloading smoother. In addition, the locking mechanism 600 is used to control the opening and closing of the outlet channel in the unloading mechanism 500, making it more convenient to control the access to materials.

[0029] The suspension mechanism 300 includes a top beam connected to the frame 200 and extending horizontally at one end outside the frame 200, a track 320 provided on the top beam, and an electric hoist 330 slidably mounted on the track 320. A hook 340 is provided below the electric hoist 330. The electric hoist 330 can reciprocate along the track 320 to allow the ton bag 100 to enter and exit the frame 200. The electric hoist 330 moves out of the frame 200 along the track 320, and the hook 340 descends to facilitate the lifting of the ton bag 100. After the ton bag 100 is suspended, the electric hoist 330 reenters the frame 200 along the track 320. This automates the suspension process and reduces the labor intensity of workers.

[0030] The suspension mechanism 300 is detachably connected to the ton bag 100 via a hanger 700. Figure 4The hanger 700 includes an inverted X-shaped frame body 710, a plurality of inclined sections 720 connected one-to-one at the corners of the frame body 710, and reinforcing ribs 730 vertically connected to the upper end of the frame body 710 and distributed in an X shape. The ends of the reinforcing ribs 730 are respectively fixed to the side walls of the inclined sections 720 at the corresponding positions, and a hanging hole 731 for hanging with the hook 340 is provided at the center of the X-shaped reinforcing ribs 730. A hanging part 740 for hanging the sling 111 is provided at the end of each inclined section 720. The hanging part 740 includes a U-shaped hanging body 741 and a first bent portion 742 and a second bent portion 743 respectively fixed at both ends of the hanging body 741. The first bent portion 742 and the second bent portion 743 overlap in the top projection plane, and the height of the first bent portion 742 is higher than the second bent portion 743. Please continue to refer to Figure 2 The sling 111 enters the hook body 741 through the gap between the first bend 742 and the second bend 743. The first bend 742 and the second bend 743 not only form a height difference but also partially overlap in a top view. Therefore, after the sling 111 is restrained within the hook body 741, the end of the first bend 742 faces toward the second bend 743, while the end of the second bend 743 faces toward the first bend 742. This coordination of the two bends prevents the sling 111 from escaping from the hook body 741, providing a more effective restraining effect. The angle between the inclined section 720 and the frame body 710 is obtuse, so the top end face of the inclined section 720 is higher than the top end face of the frame body 710. Using the hook 740 to attach the sling 111 shortens the lifting stroke of the ton bag 100, ensuring a more balanced force on the ton bag 100 and facilitating a more stable suspended ton bag 100.

[0031] The discharge mechanism 500 is connected to the frame 200 via a second mounting bracket. The second mounting bracket includes two second mounting rods 220 spaced apart and connected to the inner wall of the frame 200, and two third mounting rods 230 spaced apart. Each third mounting rod 230 is connected between two second mounting rods 220. The second and third mounting rods 220, 230 form a mounting cavity for mounting the discharge mechanism 500. The discharge mechanism 500 includes a discharge hopper 510 mounted within the mounting cavity, a bag pressing mechanism 520 mounted above the discharge hopper 510, and a dust removal mechanism located on one side of the discharge hopper 510. The bottom end of the discharge hopper 510 defines an outlet channel. The top end of the discharge hopper 510 is provided with an annular groove 511 recessed away from the bag pressing mechanism 520. The annular groove 511 is concentric with the top end of the discharge hopper 510. A plurality of third side wings 513 are provided on the outer periphery of the discharge funnel 510 . The third side wings 513 can be screwed to the second mounting rod 220 or the third mounting rod 230 to stably mount the discharge mechanism 500 in the frame 200 .

[0032] See also Figure 5 The bag pressing mechanism 520 includes two first side wings 521 symmetrically arranged on the outer wall of the discharge hopper 510, two second driving cylinders 522 connected to the first side wings 521 in a one-to-one relationship, a bag pressing plate 523 connected to the two second driving cylinders 522 and located above the discharge hopper 510, and two guide shafts 524 for guiding the movement of the bag pressing plate 523. Each side of the bag pressing plate 523 has a second side wing 5230 positioned corresponding to the first side wing 521. The second driving cylinders 522 and the guide shafts 524 are both connected to the second side wings 5230. The bag pressing plate 523 has a bag inlet 5231 whose axis is aligned with the top end of the discharge hopper 510. The bag inlet 5231 and the top end of the discharge hopper 510 form an inlet channel for the bag spout 120 to enter. The lower end of the bag inlet 5231 is provided with an annular flange. The second driving cylinder 522 can drive the bag pressing plate 523 to move toward or away from the discharge funnel 510 , and the annular flange can abut against the top surface of the discharge funnel 510 .

[0033] The cable tie of the ton bag 100 is tied at the connection position between the bag mouth 120 and the bag body 110. When the above-mentioned unloading mechanism 500 is used, after the suspended ton bag 100 enters the frame 200, the manually assisted bag mouth 120 first enters the bag inlet 5231, and the tied and tightened part is aligned with the top port of the unloading funnel 510, while the edge of the bag mouth 120 that is not constrained extends outward into the annular groove 511, and the second driving cylinder 522 is started, and the bag pressing plate 523 moves toward the direction close to the unloading funnel 510 until the annular flange cooperates with the pressing surface 512 of the unloading funnel 510 to jointly press the bag mouth 120, completing the tightening of the bag mouth 120, and then untie the cable tie, and the molding sand in the bag body 110 can be aligned with the port of the unloading funnel 510 and enter the interior of the unloading funnel 510, temporarily unloading the material into the hollow unloading funnel 510. The advantage of the bag pressing mechanism 520 is that it can limit the position of the ton bag 100 at the bag mouth 120 during the unpacking process to prevent the ton bag 100 from moving and affecting the lower material. The leaked molding sand can be collected in the annular groove 511 for easy cleaning.

[0034] During the unloading process, in order to reduce dust interference, the outer wall of the unloading funnel 510 is further provided with a dust removal interface 514 communicating with the interior. The dust removal interface 514 is used to connect with a dust removal mechanism, and the dust removal mechanism preferably adopts a bag dust collector.

[0035] The locking mechanism 600 is a manual butterfly valve installed at the bottom port of the discharge funnel 510. It is simple to operate, highly reliable, and easy to replace or repair. By operating the manual butterfly valve, the discharge process can be controlled, so that when taking materials, the outlet channel can be opened or closed according to actual conditions.

[0036] The flapping mechanism 400 is connected to the frame 200 via a first mounting frame, which includes two first mounting rods 210 spaced apart and connected to the inner wall of the frame 200. The first mounting rods 210 are located above the second mounting rod 220 and the third mounting rod 230 to enable flapping of the bag body 110 after the flapping mechanism 400 is installed.

[0037] See also Figure 3 The flapping mechanism 400 includes two symmetrically arranged flapping components 410, all of which include two detachably connected bearing 412 seats 411 distributed one-to-one on the upper ends of the two first mounting rods 210, bearings 412 installed in the bearing 412 seats 411, a flapping plate 413 arranged between the two bearings 412 and rotatably connected to the corresponding bearings 412 at both ends, and a first driving cylinder 414 connected to the flapping plate 413 at one end and the frame 200 at the other end. The first driving cylinder 414 is arranged at an angle. When the bag mouth 120 enters the inlet channel, the first driving cylinder 414 can drive the two flapping plates 413 to move back and forth in the direction of approaching or moving away from the bag body 110. When the first driving cylinder 414 is not started, the opening is located between the two flapping plates 413. After the first driving cylinder 414 is started, the two flapping plates 413 cooperate with each other to flap the bag body 110, which can loosen the compacted material and help the material enter the discharge funnel 510 more smoothly.

[0038] See also Figure 2 Several through-cavities 4130 are spaced along the length of the flapping plate 413. When flapping the ton bag 100, the through-cavities 4130 act as a buffer and disperse force, allowing the flapping force to be more evenly transmitted to all parts of the ton bag 100. Furthermore, the presence of the through-cavities 4130 increases the elasticity of the flapping plate 413, making the flapping action softer yet more powerful, helping to more effectively break down lumps and agglomerates in the ton bag 100.

[0039] Please continue reading Figure 3 The material receiving mechanism is a screw conveyor 800 (auger), or alternatively, a conveying device with a conveyor belt. This embodiment uses the screw conveyor 800 as an example. The inlet of the screw conveyor 800 is aligned with the bottom port (i.e., the outlet channel) of the discharge hopper 510, while the outlet is away from the frame 200. This allows the material discharged from the discharge hopper 510 to be conveyed in a straight line to a location away from the frame 200, making it more convenient and efficient to access the molding sand material.

[0040] See also Figure 6In another embodiment, the material receiving mechanism includes a weighing mechanism 900A, a material receiving bucket 900B placed on the top of the weighing mechanism 900A, and a bucket cover 900C detachably connected to the top of the material receiving bucket 900B. The material receiving bucket 900B has a discharge port communicating with the interior, and the top of the bucket cover 900C has a material receiving port. The top of the material receiving port communicates with the outlet channel, while the bottom communicates with the interior of the material receiving bucket 900B. The weighing mechanism 900A is preferably a floor scale. Such a material receiving mechanism facilitates quantitative charging during the casting process, because the material discharged from the outlet channel of the discharge funnel 510 enters the material receiving port and is collected in the material receiving bucket 900B. The weighing mechanism 900A then weighs the material in the receiving bucket 900B to obtain a quantitative amount of material for charging.

[0041] This unpacking device: 1. When unpacking a ton bag 100, the ton bag 100 is suspended into the frame 200 using the suspension mechanism 300. The hook 340 descends until the bag mouth 120 is pressed by the bag pressing mechanism 520. After the bag mouth 120 is untied, the material in the bag body 110 enters the discharge funnel 510. The locking mechanism 600 controls the opening and closing of the discharge funnel 510 outlet channel. The material in the outlet channel is then transported through the material receiving mechanism, making it convenient for material to be taken. The entire unpacking process is highly automated, saving manpower and reducing the labor intensity of workers. 2. After the bag mouth 120 is inserted into the inlet channel, the bag pressing plate 523 in the bag pressing mechanism 520 presses the bag mouth 120, fixing the ton bag 100 more stably and making it easier to accurately align the bag mouth 120 with the discharge funnel 510 port for discharge. If there is leakage of molding sand, it is collected and processed through the annular groove 511. 3. During the unpacking process, materials such as molding sand tend to clump or compact, which can hinder material discharge. The flapping mechanism 400 is activated to flap the bag 110, allowing for smoother material discharge. 4. A locking mechanism 600 is provided at the bottom of the discharge funnel 510 to control the material discharge progress, making material removal convenient and practical.

Any equivalent structure made using the contents of the description and drawings of the present invention, directly or indirectly used in other related technical fields, is also within the patent protection scope of the present invention.
