Description

Technical Field

[0001] This utility model relates to the field of ton bag packaging machine technology, and in particular to a mobile quantitative ton bag packaging machine. Background Technology

[0002] A ton bag (also known as a bulk container, jumbo bag, etc.) is a flexible storage and transportation packaging container. It is called a ton bag because its dimensions are typically a cube of approximately 1 meter x 1 meter x 1 meter, and it weighs approximately 1 ton when filled. The actual dimensions and weight vary depending on the material. These ton bags are usually made of polyester fiber, making them lightweight, foldable, and reusable. They are suitable for storing and transporting bulk powders and granular materials. They generally offer advantages such as moisture resistance, dust resistance, high loading and unloading efficiency, easy stacking and movement, and robust safety. Therefore, with the rapid development of industrial production, the specifications and styles of ton bags are becoming increasingly diverse, and their applications are becoming more widespread, especially in industries such as polyester, building materials, grain, feed, and powder metallurgy.

[0003] The earliest form of ton bag packaging typically involved a forklift arm holding the ton bag by its straps, followed by manual filling and weighing. This required multiple operators, resulted in dusty conditions, and yielded inconsistent measurement results. However, with the widespread use of ton bags, various automated ton bag weighing and packaging machines have emerged. These machines employ diverse technologies, including, but not limited to, pre-weighing (using an independent weighing hopper for weighing before packaging), top-weighing (weighing via a hanging bag with a weighing sensor above the ton bag), and bottom-weighing (weighing via a platform scale with a weighing sensor below the ton bag). Their automated filling methods include, but are not limited to, screw conveyor, gravity filling, and rotary feeding.

[0004] In existing technologies, ton bag packaging equipment often uses a large flow of compressed air to inflate the ton bags, allowing them to fully expand before filling. While this increases the filling capacity, it also consumes a significant amount of energy. Therefore, we propose a mobile quantitative ton bag packaging machine to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing ton bag packaging equipment, which often uses a large flow of compressed air to inflate the ton bags before filling, thereby increasing the filling capacity but also consuming a large amount of energy. Therefore, a mobile quantitative ton bag packaging machine is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A mobile quantitative ton bag packaging machine, comprising:

[0008] outer frame;

[0009] The exhaust mechanism includes a material pipe vertically disposed on the top of the outer frame and a perforated plate fixedly connected to the bottom outer periphery of the material pipe. An exhaust pipe of the same length as the material pipe is fixedly disposed on the outer periphery of the perforated plate. An arc-shaped exhaust pipe of the second type extends upward from the outer wall of the first type and is connected to it. The first type and the second type are Y-shaped and used to seal the lower flange fixedly connected to the second type.

[0010] The bag clamping mechanism includes a swing arm disposed on the outer periphery of the exhaust pipe along the height direction of the outer frame. A clamping plate is hinged to the swing arm and fits against the outer wall of the exhaust pipe. The clamping plate is provided with a sealing strip for sealing the ton bag and a groove for accommodating the sealing strip is provided in the concave semi-circular arc of the end face of the clamping plate. A weighing device and an inner frame fixedly connected to the weighing device are installed inside the outer frame. A crossbeam for supporting the exhaust pipe is installed on the top of the inner frame. A cylinder is fixedly mounted on the inner frame and hinged to the swing arm.

[0011] As described above, exhaust pipes one and two outside the material pipe are used to remove dust-laden gas from the bottom up during the material stacking and filling process. The sealing strip is used to clamp the bag opening of the ton bag to the outer periphery of exhaust pipe one, so that a relatively closed space is formed inside the ton bag.

[0012] Furthermore, a flexible joint and an upper flange connected to the flexible joint are installed on the lower flange along the second exhaust direction of the exhaust pipe. A steel short pipe is fixedly installed on the upper flange. A top bracket fixedly connected to the steel short pipe and an exhaust valve installed on the steel short pipe are installed on the top of the outer frame.

[0013] The exhaust valve, as described above, is used to open and close the exhaust passage, thereby better controlling the gas volume.

[0014] Furthermore, the exhaust valve consists of a steel valve body, a bracket, and a cylinder. The bracket is installed along the length of the top frame, the cylinder is fixed on the bracket, and the steel valve body is inserted into the short steel pipe and fixedly connected to one end of the cylinder.

[0015] Through the above, the cylinder can drive the steel valve body to be inserted into the steel short pipe, thereby realizing the control of the feeding speed.

[0016] Furthermore, a metering valve is installed at the top of the material pipe. The metering valve consists of a steel valve body two, a bracket two, and a segmented cylinder. The bracket two is symmetrically arranged with the bracket one. The segmented cylinder is fixed on the bracket two and fixedly connected to the steel valve body two. The steel valve body two is inserted into the top of the material pipe.

[0017] As described above, the customized pneumatic slide gate valve, which can be controlled in segments using a segmented cylinder and a steel valve body, can effectively reduce the material surge at the metering end, thereby making the metering more accurate.

[0018] Furthermore, an installation plate is fixedly provided on the outer frame along its length surface. A second cylinder is fixedly provided on the installation plate, and a pulley is provided above the second cylinder. A steel wire rope is connected to the second cylinder and passes through the pulley. A guide cylinder that is fixedly connected to the outer frame is sleeved on the steel wire rope, and a hook is provided at the bottom end of the steel wire rope.

[0019] Through the above process, the steel wire rope pulls the hook upwards via pulleys, lifting and lowering it to fully disperse and compact the material filling inside the ton bag, thereby maximizing the capacity of the ton bag.

[0020] Furthermore, a column is fixedly installed on the top of the outer frame below the second exhaust pipe. An adjustment plate that is slidably mounted on the outer frame is connected to the column by a spring. An adjustment bolt is connected to the end of the adjustment plate away from the spring. A fixing plate and a threaded hole that engages with the adjustment bolt are fixedly installed on the fixing plate next to the adjustment plate.

[0021] As described above, the adjusting plate can be moved and adjusted by adjusting the bolts, thereby stretching the spring so that the inner frame and the outer frame always maintain a suitable distance, without causing additional impact on the weight.

[0022] Furthermore, the bottom of the outer frame is provided with movable casters and a fixed foot plate that can be vertically adjusted and mounted on the movable casters.

[0023] As described above, the movable casters facilitate the movement of the equipment, while the fixed feet secure the equipment.

[0024] Compared with the prior art, the advantages of this utility model are:

[0025] 1. This solution is an energy-saving and environmentally friendly semi-automatic ton bag packaging equipment with features such as mobility, non-powered gravity feeding, closed dust removal, and segmented metering. The mobile design, including heavy-duty casters, is adapted to meet the needs of multi-station, diversified, and personalized bulk material ton bag packaging.

[0026] 2. This solution utilizes gravity-fed material unloading from the silo to further reduce energy consumption during the packaging process; the closed exhaust and dust removal design, including bag clamping, Y-shaped exhaust pipes one and two, exhaust valves, and dust collectors, essentially eliminates material dust, effectively improving the working environment and reducing occupational risks for on-site employees.

[0027] 3. This solution divides the ton bag filling process into two working modes, fast filling and slow filling, through segmented metering valves, which can effectively improve the accuracy of ton bag packaging and metering. Attached Figure Description

[0036] Reference Figures 1-4 A mobile quantitative ton bag packaging machine, comprising:

[0037] Outer frame 1;

[0038] The exhaust mechanism includes a material pipe 6 vertically disposed on the top of the outer frame 1 and a perforated plate 604 fixedly connected to the bottom outer periphery of the material pipe 6. An exhaust pipe 601 of the same length as the material pipe 6 is fixedly disposed on the outer periphery of the perforated plate 604. An arc-shaped exhaust pipe 602 extends upward from the outer wall of the exhaust pipe 601. The exhaust pipe 601 and the exhaust pipe 602 form a Y-shape and are used to seal the lower flange 603 fixedly connected to the exhaust pipe 602.

[0039] The bag clamping mechanism includes a swing arm 12 disposed along the height direction of the outer frame 1 on the outer periphery of the exhaust pipe 601. A clamping plate 1202 is hinged to the swing arm 12 and fits against the outer wall of the exhaust pipe 601. A sealing strip 1203 for sealing the ton bag is provided on the clamping plate 1202, and a groove for accommodating the sealing strip 1203 is provided in the concave semi-circular arc of the end face of the clamping plate 1202. A weighing device 2 and an inner frame 3 fixedly connected to the weighing device 2 are installed inside the outer frame 1. A crossbeam 301 for supporting the exhaust pipe 601 is installed on the top of the inner frame 3. A cylinder 1201 hinged to the swing arm 12 is fixed on the inner frame 3.

[0040] In this embodiment, a flexible joint 7 and an upper flange 801 connected to the flexible joint 7 are installed on the lower flange 603 along the exhaust direction of the exhaust pipe 602. A steel short pipe 8 is fixedly installed on the upper flange 801. A top bracket 5 fixedly connected to the steel short pipe 8 and an exhaust valve 9 installed on the steel short pipe 8 are installed on the top of the outer frame 1.

[0041] In this embodiment, the exhaust valve 9 consists of a steel valve body, a bracket, and a cylinder. The bracket is installed along the length of the top frame 5, the cylinder is fixed on the bracket, and the steel valve body is inserted into the steel short pipe 8 and fixedly connected to one end of the cylinder.

[0042] In this embodiment, a metering valve 10 is installed on the top of the material pipe 6. The metering valve 10 consists of a steel valve body 2, a bracket 2, and a segmented cylinder. The bracket 2 is symmetrically arranged with the bracket 1. The segmented cylinder is fixed on the bracket 2 and fixedly connected to the steel valve body 2. The steel valve body 2 is inserted into the top of the material pipe 6.

[0043] In this embodiment, an installation plate 13 is fixedly provided on the outer frame 1 along its length. A cylinder 1301 is fixedly provided on the installation plate 13, and a pulley 1303 is provided above the cylinder 1301. A steel wire rope 1302 is connected to the cylinder 1301 and passes through the pulley 1303. A guide cylinder 1305 fixedly connected to the outer frame 1 is sleeved on the steel wire rope 1302. A hook 1304 is provided at the bottom end of the steel wire rope 1302. The cylinder 1301 can pull the steel wire rope 1302 to drive the hook 1304 to move upward with the pulley 1303 as the fulcrum.

[0044] In this embodiment, a column 4 is fixedly installed on the top of the outer frame 1 below the exhaust pipe 602. An adjusting plate 402, which is slidably mounted on the outer frame 1, is connected to the column 4 via a spring 401. An adjusting bolt 404 is connected to the end of the adjusting plate 402 away from the spring 401. A fixing plate 403 is fixedly installed on the outer frame 1 next to the adjusting plate 402, and a threaded hole is opened on the fixing plate 403 to engage with the adjusting bolt 404. By rotating the adjusting bolt 404, the adjusting plate 402 is moved, which in turn stretches the spring 401.

[0045] In this embodiment, the bottom of the outer frame 1 is provided with movable casters 14 and a fixed foot plate 15 that can be vertically adjusted on the movable casters 14. By adjusting the fixed foot plate 15 up and down, it can be brought closer to or in contact with the ground to achieve the effect of fixing and unfixing.

[0046] The implementation principle of a mobile quantitative ton bag packaging machine according to an embodiment of this application is as follows: When a hopper needs to be packaged into ton bags, the handwheel of the fixed foot plate 15 is manually rotated counterclockwise (or the hydraulic cylinder piston is manually retracted by operating the hydraulic device), causing the plate surface of the fixed foot plate 15 to leave the ground. After the equipment loses the fixed support of the fixed foot plate 15, it can move. After the equipment is manually moved to the corresponding position at the bottom of the corresponding hopper, the handwheel of the fixed foot plate 15 is manually rotated clockwise (or the hydraulic cylinder piston is manually extended by operating the hydraulic device), so that the plate surface of the fixed foot plate 15 is firmly pressed against the ground. The equipment will be unable to move under the fixed support of the fixed foot plate 15. The corresponding connecting pipe is used to seal the connection between the hopper port flange and the inlet flange of the metering valve 10 of the equipment. Simultaneously, the power and air supply of the equipment are connected, and the valve at the bottom of the hopper is opened to connect the pipeline between the hopper and the equipment. After the moving and positioning stage is completed, the pallet is placed on the inner frame 3 manually, and the lifting straps at the four corners of the ton bag are inserted into the lifting hooks 1304 manually. Then, the bag opening of the ton bag is placed on the bottom outer periphery of the exhaust pipe 601 outside the material pipe 6. The piston rod of the cylinder 1201 of the bag clamping mechanism is simultaneously inflated and extended, pushing the swing shaft to move. Both swing arms 12 press the concave surface of the clamping plate 1202 against the outer circular surface of the Y-shaped exhaust pipe 601 with the fixed shaft as the center. Thus, the sealing strip 1203 tightly clamps the bag opening of the ton bag on the outer circle of the Y-shaped exhaust pipe 601 to the outer wall of the exhaust pipe 601, achieving the corresponding sealing effect. The balancing device 2 is cleaned by the automated program. Zero, then click the start button of the control program to start the ton bag packaging. The control program automatically sends a valve opening signal, and the metering valve 10 automatically opens to 100% (not adjustable, metering valve 10 is in fast-increasing state). Under the action of gravity, the material in the hopper falls rapidly from top to bottom through the steel short pipe 8, flexible joint 7, and material port B of the material pipe 6. The material enters the ton bag through material pipe 6 and outlet D and continues to pile up, and the air pressure inside the ton bag increases accordingly. At the same time, the exhaust valve 9 automatically opens under the action of the automatic control program. While the material continues to enter the ton bag, the gas of the mixed material dust inside the ton bag enters from bottom to top through the gas collection port C into exhaust pipe 1 601 and exhaust pipe 2 602, and then passes through the Y-shaped exhaust port A, exhaust valve 9, and flexible joint 602 in sequence. Connector 7 and short steel pipe 8 reach the interior of dust collector 11. Because dust collector 11 is equipped with a filter element, clean gas diffuses into the atmosphere through the filter element, while the mixed material is blocked by the filter element and falls back into the ton bag through exhaust pipe 601 and exhaust pipe 602. A small portion adheres to the inner wall of the filter element. Over time, the bulk material in the ton bag accumulates, causing the bottom of the flexible ton bag to sag under the weight of the material. The four corners of the ton bag are not fully filled, resulting in a typical upward-arched state. Therefore, this equipment uses a control program to automatically or manually extend the piston rod of cylinder 1201 of the bag-hanging mechanism, raise the guide rod, and loosen the steel wire rope 1302. Under the weight of the material, the ton bag descends onto the tray on the bottom plate of the inner frame 3.The bottom arch is disrupted, and the material piled high in the upper and lower arches is spread out, allowing the material to diffuse around the ton bag to fully fill the corners. Then, the control program automatically or manually depresses the rodless chamber of cylinder 1201 of the bag-hanging mechanism while simultaneously inflating the rod chamber. The piston rod of cylinder 1201 retracts, the guide rod descends, and the steel cable 1302 is pulled back. The ton bag rises again under the pull of the steel cable 1302, and the bottom of the ton bag loses the support of the tray and becomes suspended. The material inside the ton bag is stretched upwards at the four corners, creating an upward-concave and downward-arched shape. However, the concave space is quickly filled and piled up by the continuously falling material, returning to the upward-and-downward-arched state. The ton bag needs to be lowered back onto the tray to allow the material to spread and fill around the ton bag. This process is repeated several times to fully spread, fill, and compact the continuously piling material in the center of the ton bag, ensuring uniform filling until the weight of the material inside reaches the first set value (a lead time for the packaging weight, which can be adjusted and set through on-site testing based on the feeding height and material shape). Then, the ton bag is lowered onto the tray on the bottom plate of the inner frame 3. When the material inside the ton bag reaches the first set value, the control program sends a secondary valve opening signal. Metering valve 10 is partially closed, only 30% open (adjustable ratio, metering valve 10 is in slow filling state). The area passing through metering valve 10 is reduced to 30% (adjustable ratio), and the material filling speed of the ton bag becomes slow until the weight of the ton bag reaches the second set value (the packaging weight to be filled). Under the action of the control program, metering valve 10 is quickly and completely closed, and weighing is completed. After weighing, the operator manually squeezes any remaining gaps at the top of the ton bag to expel the gas inside. The operator then operates the switch to release the bag clamping mechanism, and at the same time, the control program automatically closes the exhaust valve 9. The operator manually uses the straps on the ton bag to tighten the opening and removes the four lifting straps around the ton bag from the hooks 1304 of the bag hanging mechanism. A forklift is used to remove the ton bag (or ton bag and pallet) from the equipment, and a new ton bag (or ton bag and pallet) is placed in to start another automatic metering and filling of the ton bag. This process is repeated continuously. In the ton bag packaging process, when the material in the connected hopper has been used up and emptied, or the hopper is not emptied but ton bag packaging has been completed and the hopper door is closed, a situation may arise where the weight of the last ton bag (referred to as the last bag) does not reach the set value, and the metering valve 10 cannot close. Manual intervention is required. One method is to manually replenish the ton bag to reach the second set value (the packaging weight to be filled), and the control program will automatically close the exhaust valve 9 and metering valve 10 completely. Another method is to remove the underweight ton bag for later use, and manually end the control program to automatically close the exhaust valve 9 and metering valve 10 completely. After confirming that the hopper door is closed, the connecting pipe between the hopper and the equipment is emptied, the exhaust valve 9 is closed, and the metering valve 10 is completely closed, the connection between the equipment and the hopper can be disconnected, the power and air supply can be turned off, and the air supply and electrical connections can be disconnected. Cables can then be stored away.

[0047] All structures in this application can be customized in terms of material and length according to actual usage. The attached drawings are schematic structural diagrams, and the actual dimensions can be adjusted accordingly.

Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in this embodiment, based on the technical solution and the inventive concept of this embodiment, should be covered within the scope of protection of this embodiment.
