Technical Field

[0001] This utility model relates to the field of bag breaking and material extraction technology, and in particular to a fly ash ton bag bag breaking and material extraction device. Background Technology

[0002] In fly ash resource utilization and harmless treatment projects, it is necessary to remove the material from the ton bags. Currently, the industry generally uses conical blades or shredders to break open the ton bags containing fly ash, and then uses screening equipment to separate the fly ash material from the broken ton bag fragments.

[0003] The following problems exist in the current bag breaking process: After the ton bag is shredded by the conical blade or shredder, it easily generates a large number of small fragments, which mix with the fly ash material. Subsequent screening equipment cannot completely separate them, which may cause the fragments to enter the subsequent processing system, affecting product quality or causing equipment blockage.

[0004] To address the aforementioned issues, the industry needs a bag-breaking and material-retrieving device that offers good separation performance and facilitates the removal of empty bags (i.e., bags after the material inside the ton bag has been discharged). Utility Model Content

Detailed Implementation

[0019] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0020] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0021] Reference Figures 1 to 7 As shown, this utility model embodiment provides a fly ash ton bag breaking and material handling device for transferring the material in the ton bag 1 to the hopper 2; the material handling device mainly includes a frame 3, a conveyor 4, a bag breaking mechanism 5 and a bag gripping mechanism 6.

[0022] The conveyor 4 is used to transport the ton bag 1 and can rotate relative to the frame 3 between a first position and a second position; the bag breaking mechanism 5 is disposed at the output end of the conveyor 4; when the ton bag 1 moves to the bag breaking station with the conveyor 4, the actuating end of the bag breaking mechanism 5 breaks the top of the ton bag 1; the bag gripping mechanism 6 is connected to the conveyor 4 and rotates synchronously with it; the bag gripping mechanism 6 has at least one power-driven gripper 61, which is configured to grip the bottom of the ton bag 1 when the ton bag 1 moves to the bag breaking station; when the conveyor 4 rotates from the first position to the second position, its input end gradually flips upward so that the material on the conveyor 4 and / or inside the ton bag 1 can fall into the hopper 2.

[0023] In actual production applications: Conveyor 4 is initially in the first position (horizontal or low-angle inclined state), and the ton bag 1 is placed at the input end of conveyor 4 and conveyed to the bag-breaking station. After the ton bag 1 arrives at the bag-breaking station, the bag-breaking mechanism 5 breaks the top of the ton bag 1; at the same time, the gripping mechanism 6 grips the bottom of the ton bag 1 under power drive, so that the ton bag 1 is in a state of top opening and bottom fixation. Subsequently, conveyor 4 rotates from the first position to the second position, and its input end gradually flips upward, so that the entire conveyor 4 forms a high-angle inclination. At this time, with the bottom of the ton bag 1 fixed by the gripping claw 61, the internal material falls into the hopper 2 below through the top opening under the action of gravity, completing the unloading. During the unloading process, the material remaining on the surface of conveyor 4 also slides down the inclined surface into the hopper 2; then the empty ton bags 1 remaining on conveyor 4 can be collected by the staff or removed by other automated equipment.

[0024] In summary, compared to existing technologies, this application eliminates the need for a shredder. Instead, the ton bag 1 is conveyed to the breaking station via a conveyor 4. The gripper 61 holds the bottom of the ton bag 1 to secure it. After the top of the ton bag 1 is broken by the breaking mechanism 5, it is then flipped and unloaded by the conveyor 4. The material is naturally discharged into the hopper 2 by gravity, resulting in complete separation of the ton bag 1 and the material, eliminating the need for additional screening equipment. Furthermore, the conveyor 4 can be configured as a self-driving device to transport the ton bag 1 to the breaking station. Alternatively, even without self-driving, the conveyor 4 can be rotated from the first position to the second position, tilting it so that the ton bag 1 slides down to the breaking station under its own weight.

[0025] In some practical applications, refer to Figures 2 to 3 As shown, the bag-breaking mechanism 5 includes a lifting frame 51, a first rotating shaft 52, and several cutting wheels 53.

[0026] A lifting frame 51 is fixedly connected to the conveyor 4; a first rotating shaft 52 is rotatably connected to the lifting frame 51 and is driven to rotate by a power source; at least one cutting wheel 53 is configured and coaxially mounted on the first rotating shaft 52; the cutting wheel 53 rotates synchronously with the first rotating shaft 52 to cut and puncture the top of the ton bag 1 conveyed below it. Specifically, a first rotary motor 54 is also provided on the lifting frame 51, and its output shaft is connected to the first rotating shaft 52 to drive the first rotating shaft 52 and the cutting wheel 53 to rotate.

[0027] As the ton bag 1 moves towards the bag-breaking station with the conveyor 4, the first rotary motor 54 on the lifting frame 51 drives the first rotating shaft 52 to rotate, causing the coaxially mounted cutting wheel 53 to rotate at high speed (the number of cutting wheels 53 can be configured individually or in multiples according to the size of the ton bag 1 to ensure sufficient breaking area). When the ton bag 1 is conveyed directly below the cutting wheel 53, the high-speed rotating cutting wheel 53 contacts the top of the ton bag 1 and cuts the surface of the ton bag 1, forming a break (the break position can be determined by the height of the lifting frame 51). During the breaking process, the ton bag 1 is gripped and fixed by the bag-grabbing mechanism 6. This device uses a high-speed rotating cutting wheel 53 to break the bag. During the cutting process, the contact between the blade and the ton bag 1 is only on the surface of the ton bag 1, reducing the contact area with the fly ash particles inside, which also reduces the wear of the cutting wheel 53 to some extent. When the bag-grabbing mechanism 6 grips the bottom of the ton bag 1 and flips it over, the bag remains intact (only the top is open), and the material is discharged through the opening, minimizing the mixing of bag and material fragments, and achieving separation without additional screening equipment.

[0028] In other practical applications, the lifting frame 51 is configured as an electric telescopic rod structure (not shown in the figure). The rotating shaft is installed at the telescopic end of the electric telescopic rod. The height of the rotating shaft and the cutting wheel 53 is adjusted by the telescopic action of the electric telescopic rod. Therefore, the electric telescopic rod can adjust the height of the cutting wheel 53 in real time to be suitable for ton bags 1 of different sizes within a certain range.

[0029] In some practical applications, refer to Figures 1 to 2 As shown, a bracket 31 is rotatably connected to the frame 3, and the conveyor 4 is located above the bracket 31 and is mounted on the bracket 31 through several sets of elastic support components 7. A vibrating motor 8 is also installed on the frame of the conveyor 4.

[0030] Specifically, refer to Figure 4As shown, two bearing seats 32 are mounted on the frame 3, and a rotating shaft 33 driven by a power source is installed between the two bearing seats 32. The rotating shaft 33 is fixedly mounted on the bracket 31 so that the conveyor 4 can move between a first position and a second position by rotating the rotating shaft 33. A second rotary motor 34 is also mounted on the frame 3, and its output shaft is connected to the rotating shaft 33 to drive the rotating shaft 33 to rotate.

[0031] Specifically, refer to Figure 5 As shown, each set of elastic support components 7 includes a guide post 71, a limiting part 72, and a spring 73. The guide post 71 is longitudinally mounted on the bracket 31, and the guide post 71 passes through the frame of the conveyor 4 and slides with it; the limiting part 72 is fixedly mounted on the guide post 71 to prevent the frame of the conveyor 4 from detaching from the guide post 71; the spring 73 is sleeved on the guide post 71 to elastically support the frame of the conveyor 4.

[0032] In this embodiment, two bearing seats 32 are installed on the frame 3 to support the rotating shaft 33. The bracket 31 is fixed on the rotating shaft 33, and the conveyor 4 is installed above the bracket 31 through the elastic support assembly 7. The output shaft of the second rotary motor 34 is connected to the rotating shaft 33 via a transmission connection (such as a coupling) to drive the rotating shaft 33 to rotate in both directions, thereby causing the bracket 31 and the conveyor 4 to rotate as a whole between the first position (horizontal or low-angle conveying position) and the second position (high-angle unloading position).

[0033] The limiting part 72 of each set of elastic support components 7 is fixed to the top of the guide column 71 to prevent the conveyor 4 from detaching from the guide column 71 due to vibration or overturning; the spring 73 is sleeved on the guide column 71 to elastically support the frame 3 of the conveyor 4, so that a flexible connection is formed between the conveyor 4 and the bracket 31. When the conveyor 4 rotates to the second position, the bottom of the ton bag 1 is fixed by the bag gripping mechanism 6, and the top opening faces downward; the vibration motor 8 starts, and the surface of the conveyor 4 and the ton bag 1 generate high-frequency vibration under the support of the spring 73, causing the material remaining in the ton bag 1 to detach from the bag and fall into the hopper 2; the vibration also acts on the surface of the conveyor 4, shaking the remaining material into the hopper 2, avoiding the accumulation of material in the gaps of the conveyor belt or conveyor wheels.

[0034] In some practical applications, based on any of the above implementation methods: Refer to Figures 6 to 7As shown, the bag-gripping mechanism 6 includes a mounting frame 62, lever arms 63, and grippers 61. The mounting frame 62 is fixedly mounted on the frame of the conveyor 4; two sets of lever arms 63 are configured and rotatably mounted on the mounting frame 62, the two sets of lever arms 63 are symmetrically arranged and driven by power to achieve relative or opposite rotation; two grippers 61 are configured, both of which are pneumatic grippers 61, and the two grippers 61 are respectively mounted on the two sets of lever arms 63; when the ton bag 1 is at the bag-breaking station, the two lever arms 63 rotate relative to each other to drive the two grippers 61 to move to both sides of the bottom of the ton bag 1, and the two grippers 61 actuate and clamp the bottom of the ton bag 1.

[0035] Specifically, the bag-grabbing mechanism 6 also includes linear cylinders 64 respectively arranged corresponding to the two lever arms 63; the base end of the linear cylinder 64 is hinged to the mounting frame 62, and the actuating end of the linear cylinder 64 is hinged to the corresponding lever arm 63; the linear cylinder 64 is actuated to push the lever arm 63 to rotate.

[0036] In this embodiment, the mounting frame 62 is fixed to the conveyor 4 frame 3 and rotates synchronously with the conveyor 4; two sets of lever arms 63 are rotatably connected to the mounting frame 62 via rotating shafts and are symmetrically distributed (e.g., Figure 6 (As shown); two grippers 61 are respectively installed at the ends of two sets of lever arms 63, and have pneumatically driven opening and closing functions (the working principle of pneumatic grippers is existing technology and will not be described in detail; a custom cylinder of model MGPL20-50 can be used); each set of lever arms 63 corresponds to a linear cylinder 64, the base end of the cylinder is hinged to the mounting bracket 62, and the actuator end is hinged to the lever arm 63. The lever arm 63 is rotated by extending and retracting the linear cylinder 64.

[0037] Initially, the linear cylinder 64 retracts, the lever arm 63 is in the open position, and the distance between the two grippers 61 is greater than the bottom width of the ton bag 1, avoiding interference with the conveying of the ton bag 1 on the conveyor 4. When the ton bag 1 moves with the conveyor 4 to the bag breaking station, a sensor (such as a photoelectric switch or proximity switch) detects the bottom positioning signal of the ton bag 1. Subsequently, the linear cylinder 64 extends, pushing the two sets of lever arms 63 to rotate relative to each other, driving the two grippers 61 to move towards both sides of the bottom of the ton bag 1 until the grippers 61 are in contact with the bottom edge of the ton bag 1. The pneumatic grippers 61 are ventilated and close to grip the bottom of the ton bag 1; at the same time, the top of the ton bag 1 can be broken. During the unloading process of the conveyor 4, the linear cylinder 64 and the pneumatic grippers 61 continue to work to ensure that the bottom of the ton bag 1 does not fall off.

[0038] After the material is completely unloaded, the conveyor 4 returns from the second position to the first position. The pneumatic gripper 61 first releases the bottom of the ton bag 1, and then the linear cylinder 64 retracts. The lever arm 63 drives the gripper 61 to return to the open position, leaving the empty bag on the conveyor 4.

[0039] In some practical applications, in summary, referring to Figure 1As shown, the material handling device also includes a truss hoisting device, the execution end of which is configured as a claw 9 for grabbing the ton bag 1 to move the ton bag 1 onto the conveyor 4. As existing technology (not shown in the figure), the truss hoisting device generally includes: a truss body spanning above the input end of the conveyor 4; a movable actuator movably mounted on the truss body; and a lifting claw 9 installed on the execution end of the movable actuator, used to grip the top of the ton bag 1. The mechanical lifting claw 9 is driven by power to open and close. The truss hoisting device is configured such that the movable actuator drives the lifting claw 9 to move between the ton bag 1 storage station and the conveyor 4, so as to hoist the ton bag 1 from the storage station to the conveying plane of the conveyor 4. It should be noted that the lifting claw 9 can also directly move the ton bag 1 to the bag breaking station. When the conveyor 4 rotates from the first position to the second position, since the bottom of the ton bag 1 has been fixed and gripped, the lifting claw 9 can cancel gripping the ton bag 1. After all the material in the ton bag 1 has fallen and the conveyor 4 returns to the first position, the truss hoisting device can drive the lifting claw 9 to remove the empty bag remaining on the conveyor 4.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
