Description

Technical Field

[0001] This invention relates to the field of material conveying, specifically a flame-retardant flipping machine for logistics. Background Technology

[0002] Logistics transportation equipment, as commonly used equipment at logistics stations, is easy to install and relatively flexible. It can easily transfer goods to designated locations, improve logistics transportation efficiency, and reduce labor burden.

[0003] Logistics transportation equipment typically consists of a simple conveyor belt and a drive motor. The conveyor belt works with the drive motor to transport goods, but the goods transported on the conveyor belt are complex and diverse, and the packages are mostly made of paper and plastic, which are flammable and pose safety hazards.

[0004] At the same time, when faced with the transportation of large quantities of goods, the conveyor belt's insufficient conveying capacity will cause a large amount of goods to pile up. Furthermore, some goods are flammable and explosive, which can easily cause fires. Once a fire breaks out, the burning goods moving on the conveyor belt will cause the fire to spread rapidly, causing even greater losses. Currently, the general approach to dealing with this situation is to immediately stop the machine and suspend the conveyor belt, and then extinguish the fire. However, the fire has already spread under the conveyor belt, causing irreparable damage.

[0005] Therefore, a flame-retardant flipping machine for logistics is proposed to address the above problems. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is: the logistics flame-retardant flipping machine of the present invention includes a base disposed between two conveyor belts, and a conveying component and a flipping component are provided on the base;

[0008] The conveying assembly includes symmetrically arranged support plates, a conveyor belt between the support plates, a flipping assembly on the outer wall of the support plates, and the flipping assembly includes a support arm on the base, a reduction motor on the support arm for driving the support plates to flip, and the output end of the reduction motor is fixed to the middle part of the support plates.

[0009] Preferably, adjustment holes are provided on the side walls at both ends of the support plate. The adjustment holes are slidably connected to the rotating rollers of the conveyor belt. The ends of the rotating rollers extend outside the support plate and are fitted with rotating rings. Adjusting bolts are rotatably connected to the outer rings of the rotating rings and are rotatably connected to the support plate.

[0010] Preferably, a fire-arresting component is provided between one end of the support plate and one end of the base, and the fire-arresting component includes a strip shell fixed to the lower surface of one end of the support plate, a roller is rotatably connected inside the strip shell, a fire-arresting cloth is wound on the roller, one edge of the fire-arresting cloth extends out along the strip hole opened on the strip shell, and extends downward to be fixed to the crossbeam provided on the base.

[0011] Preferably, a water spray pipe is provided inside one end of the support plate, and multiple atomizing nozzles are provided on the water spray pipe. One end of the water spray pipe is connected to a water supply pipe, which is connected to an external water pump.

[0012] Preferably, the base has a sliding groove for the horizontal movement of the support arm, and a drive assembly is provided in the sliding groove. The drive assembly can drive the support arm to move along the sliding groove, and the drive assembly includes a lead screw set in the sliding groove, which is threadedly connected to the bottom of the support arm.

[0013] Preferably, the frame of the base is provided with an L-shaped support plate. The vertical part of the support plate is fixed to the support arm on both sides, the horizontal part of the support plate extends to the other end of the base, and the horizontal part of the support plate is fixed to the two sides of the end of the horizontal part of the support plate. The sliding rod is slidably connected to the inner wall of the frame of the base.

[0014] An L-shaped baffle is provided on the horizontal part of the pallet. The bent edge of the baffle is rotatably connected to the horizontal part of the pallet and is located near the end of the horizontal part. The reduction motor drives the support plate to flip, and the other end of the support plate is pressed against the vertical part of the baffle. The baffle deflects and blocks the heat radiation to the flipping component and the conveying component.

[0015] Preferably, the baffle is provided with an auxiliary pipe, which has multiple spray holes, and one end of the auxiliary pipe is connected to a flexible hose, which is laid along the base and connected to the other end of the water spray pipe.

[0016] Preferably, the support arm is provided with support frames on both sides, and two adjacent support frames are arranged in a figure-eight shape. Each support frame is rotatably connected to a wheel at its bottom, and the wheel is attached to the base and rolls.

[0017] Preferably, the upper surface of the base has a notch located on one side of the slide groove, and a water control component is provided inside the notch. The water control component is installed on the water supply pipe and includes a sleeve. Two channels are radially opened on the outer wall of the sleeve, and the channels are connected to the water supply pipe. A sliding pin is provided inside the sleeve. The bottom of the sliding pin is connected to the bottom of the sleeve by a spring. A through hole is radially opened on the outer wall of the sliding pin. A ramp is symmetrically provided at the upper end of the sliding pin, and the upper end of the sliding pin protrudes from the upper surface of the base.

[0018] Preferably, the roller is positioned away from the strip hole, and a cavity is left between the roller and the strip hole. The side wall of the cavity is provided with an atomizing nozzle for spraying water to cool the fireproof cloth.

[0019] The advantages of this invention are:

[0020] 1. In this invention, the logistics flame-retardant flipping machine is configured such that the support plate, together with the conveyor belt, deflects, while the lead screw pulls the support arm to move to the right. When the support plate flips, it pulls the protective cloth out from the strip shell and forms a fire barrier on the right side of the logistics flame-retardant flipping machine. As the support arm drives the conveyor assembly away from the left side of the conveyor belt, the baffle is also squeezed, deflected, and lifted by the lower edge of the other end of the support plate, forming a fire barrier on the left side of the logistics flame-retardant flipping machine. Multiple fire barriers enhance the protection of the logistics flame-retardant flipping machine and isolate burning goods.

[0021] 2. In this invention, the water spray pipe, in conjunction with the atomizing nozzle, can spray water onto the burning material on the right side of the flame-retardant flipping machine, reducing the intensity of the open flame or inhibiting its spread, while also lowering the temperature around the open flame point, allowing on-site personnel to approach and carry out effective fire extinguishing.

[0038] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0039] Example 1:

[0040] Reference Figure 1 - Figure 4 A flame-retardant flipping machine for logistics includes a base 2 disposed between two conveyor belts 1, and a conveying component and a flipping component disposed on the base 2; the conveying component includes symmetrically arranged support plates 3, a conveyor belt 4 disposed between the support plates 3, a flipping component disposed on the outer wall of the support plates 3, and the flipping component includes a support arm 5 disposed on the base 2, a reduction motor 6 disposed on the support arm 5 for driving the support plates 3 to flip, and the output end of the reduction motor 6 is fixed to the middle part of the support plates 3;

[0041] In this embodiment of the invention, the support plates 3 are symmetrically arranged, and a drive motor for driving the conveyor belt 4 is arranged between the support plates 3. The upper surface of the conveyor belt 4 is flush with the upper surfaces of the conveyor belts 1 at both ends. Figure 1 As shown, when the upper surface of the conveyor belt 4 is in a horizontal state, the conveyor belt 1 on its right pushes the goods onto the conveyor belt 4, and then the conveyor belt 4 pushes the goods onto the conveyor belt 4 on its left.

[0042] Depending on the size of the logistics transportation equipment, for example, one flame-retardant flipping machine may be installed at one end of an 8-meter-long conveyor belt 1, or one flame-retardant flipping machine may be installed at one end of a 13-meter-long conveyor belt 1; in the event of a fire, on the same material transportation line, all flipping components are driven, and the reduction motor 6 drives the support plate 3 along with the conveyor belt 4 to deflect, deflecting to such a position. Figure 2 As shown, the conveyor component is tilted and disconnects the two adjacent conveyor belts 1 on its left and right, thus cutting off the cargo conveying path. The conveyor component acts as a flame-retardant barrier, blocking the burning cargo between the two adjacent logistics flame-retardant flippers. At this time, the continued conveying of the burning material can be cut off, reducing the spread of the fire and minimizing losses, while also giving on-site personnel time to extinguish the fire.

[0043] In this first embodiment, the conveying component of the flame-retardant flipping machine can be conveyed not only by a conveyor belt, but also by a chain plate, with the chain plate and sprockets conveying the material. Alternatively, multiple rollers arranged side by side can be used for conveying. Each conveying method has its own advantages and disadvantages, as described below:

[0044] The advantages of conveyor belt 4 are that it is suitable for materials of various shapes and sizes, including bulk materials, packaged items, small particles, etc.; it can easily achieve long-distance conveying of hundreds of meters or even thousands of meters, with simple structure, convenient maintenance, and easy replacement and repair.

[0045] Its disadvantages include limited load-bearing capacity, unsuitability for conveying excessively heavy or sharp materials, easy damage to the belt, poor adaptability to harsh environments, high temperature, high humidity, high corrosion, and oily environments will accelerate belt aging, easy slippage and deviation, and the need for regular tension adjustment and correction. In particular, when conveying wet or sticky materials, cleaning is difficult, and dirt and grime can easily accumulate on the belt surface and in the gaps, making it unsuitable for scenarios with extremely high hygiene requirements.

[0046] Chain conveyors offer several advantages, including extremely high load-bearing capacity, robust metal chain structure capable of withstanding very heavy loads and large items, resistance to harsh environments (high and low temperatures, corrosion, and wear), suitability for demanding conditions such as casting, metallurgy, and chemical industries, stable conveying, precise positioning, and minimal chain slippage, ensuring stable material position during transport. They are ideal for automated production lines requiring precise stopping. Furthermore, they adapt to complex paths, enabling various complex conveying routes such as climbing, turning, and descending.

[0047] Its disadvantages include high cost, with initial purchase and manufacturing costs significantly higher than belt conveyors; higher operating noise, as the meshing of the chain and sprockets generates mechanical noise, typically higher than belt conveyors; relatively complex maintenance, as the chain requires regular lubrication, tensioning, and wear checks, and replacing parts may require disassembling a significant portion of the structure; and slower operating speed, typically suitable for low- to medium-speed conveying scenarios, where noise and wear will intensify at high speeds.

[0048] Roller conveyors offer several advantages, including high load-bearing capacity, making them particularly suitable for conveying heavy items with flat bottoms such as pallets, containers, and crates; modular design for high flexibility, allowing for easy combination, expansion, turning, and diversion to adapt to complex logistics layouts; simple maintenance, with a simple roller structure making it very convenient to replace a single damaged roller; low operating costs, as unpowered rollers (gravity rollers) rely on human or gravity propulsion, consuming almost no energy; and adaptability to materials with different bottom shapes, as adjusting the roller spacing can accommodate materials of different sizes and bottom shapes.

[0049] Its disadvantages are that it is only suitable for a limited range of materials, and is not suitable for bulk materials, small particles, or irregularly shaped materials with uneven bottoms; it has high requirements for the bottom of the items, requiring the bottom of the items to be flat and have a certain degree of rigidity, otherwise it is easy to get stuck or fail to be conveyed; the conveying line is relatively fixed, and although it can turn, its path flexibility is slightly worse than that of belts and chain plates, and it is not suitable for long-distance complex paths.

[0050] In summary, the conveying method can be flexibly selected according to the type of material being conveyed, and different conveying methods can be flexibly changed between the two opposing support plates 3 to meet different needs.

[0051] Reference Figure 1 - Figure 4 Adjustment holes are provided on the side walls at both ends of the support plate 3. The adjustment holes are slidably connected to the rotating roller 7 of the conveyor belt 4. The end of the rotating roller 7 extends to the outside of the support plate 3 and is fitted with a rotating ring 8. An adjustment bolt 9 is rotatably connected to the outer ring of the rotating ring 8. The adjustment bolt 9 is rotatably connected to the support plate 3.

[0052] The adjusting bolt 9 is used to adjust the tension of the conveyor belt 4. When the fire triggers the flapping action, the conveyor belt 4 with moderate tension can quickly disengage from the transmission state, reducing the delay caused by slippage or slack. At the same time, it forms a tighter break with the adjacent conveyor belts 1 on the left and right, preventing the burning goods from continuing to be conveyed forward through the gap, ensuring that an effective flame-retardant barrier can be formed after the flapping, and completely disconnecting the conveying path.

[0053] Example 2:

[0054] Reference Figure 5 - Figure 10 Compared with Embodiment 1, as another embodiment of the present invention, a fire-arresting component is provided between one end of the support plate 3 and one end of the base 2, and the fire-arresting component includes a strip shell 10 fixed to the lower surface of one end of the support plate 3, a roller 11 is rotatably connected inside the strip shell 10, a fire-arresting cloth 12 is wound on the roller 11, and one edge of the fire-arresting cloth 12 extends out along the strip hole 13 opened on the strip shell 10 and extends downward to be fixed to the crossbeam 14 provided on the base 2.

[0055] Considering the heat radiation from open flames, protecting the flame-retardant flipping machine for logistics, which is not in direct contact with open flames, can reduce damage and logistics losses. For this purpose, a fire-retardant cloth 12 is installed. Specifically, the roller 11 is connected to the strip shell 10 through a torsion spring. When the conveying component is in a horizontal state, the roller 11 rolls up the protective cloth. When the conveying component flips, the protective cloth is pulled out from the strip shell 10 and forms a heat insulation barrier between the high end of the conveying component and the base 2. This reduces the damage of the flame-retardant flipping machine to the logistics from heat radiation on the right side. It can not only effectively reduce heat radiation, but also play a fire-retardant role, assisting the conveying component and improving the fire-retardant effect.

[0056] Reference Figure 5 - Figure 7 The support plate 3 has a water spray pipe 15 inside one end, and multiple atomizing nozzles 16 are provided on the water spray pipe 15. One end of the water spray pipe 15 is connected to a water supply pipe 17, which is connected to an external water pump.

[0057] The water spray pipe 15, in conjunction with the atomizing nozzle 16, can spray water onto the burning material on the right side of the flame-retardant flipping machine, reducing the intensity of the open flame or inhibiting its spread. The unburned goods on the right conveyor belt 1 are sprayed with water, which can effectively hinder the spread of the open flame and reduce the temperature around the open flame, allowing on-site personnel to approach and carry out effective fire extinguishing.

[0058] Reference Figure 5 , Figure 7 , Figure 9 and Figure 12 The base 2 has a sliding groove 18 for the horizontal movement of the support arm 5. A drive assembly is provided in the sliding groove 18. The drive assembly can drive the support arm 5 to move along the sliding groove 18. The drive assembly includes a lead screw 19 set in the sliding groove 18. The lead screw 19 is threaded to the bottom of the support arm 5.

[0059] If there is also an open flame on the left conveyor belt 1 of the flame-retardant flipping machine, the drive component can keep the conveyor component and the flipping component away from the open flame on the left, increasing the heat radiation distance of the open flame on the left, which also protects the flame-retardant flipping machine. Specifically, firstly, the flipping component drives the conveyor component to flip. When the flipping angle is half of the flipping angle, the drive component is activated again. This design frees up space on the right side of the flame-retardant flipping machine, allowing the right conveyor belt 1 to move relatively to a position below one end of the support plate 3. The drive component also includes a servo motor that drives the lead screw 19 to rotate. The servo motor drives the lead screw 19 to rotate, and the lead screw 19 pulls the support arm 5 to move to the right. During the movement, the flipping component drives the conveyor component to deflect. When the conveyor component deflects to its position, the flipping component and the conveyor component also move to their positions. At this time, the flipping component and the conveyor component are away from the open flame on the left conveyor belt 1, reducing the heat radiation of the open flame on the right to the flame-retardant flipping machine.

[0060] Reference Figure 5 , Figure 7 , Figure 9 and Figure 12 The base 2 has an L-shaped support plate 20 inside its frame. The vertical part of the support plate 20 is fixed to the support arm 5 on both sides. The horizontal part of the support plate 20 extends to the other end of the base 2. The horizontal part of the support plate 20 is fixed to the two sides of the end of the horizontal part of the support plate 20. The slide rod 21 is slidably connected to the inner wall of the frame of the base 2.

[0061] The horizontal part of the pallet 20 is provided with an L-shaped baffle 22. The bent edge of the baffle 22 is rotatably connected to the horizontal part of the pallet 20 and is set near the end of the horizontal part. The reduction motor 6 drives the support plate 3 to flip. The other end of the support plate 3 is pressed against the vertical part of the baffle 22. The baffle 22 deflects and blocks the heat radiation to the flipping component and the conveying component.

[0062] When the flip angle is half of the flip angle, the lower edge of the other end of the support plate 3 has not yet touched the vertical part of the baffle 22. When the support arm 5 moves a certain distance to the right, for example, when it moves half of the total stroke, the support plate 3 flips and presses against the vertical part of the baffle 22. At this time, the horizontal end of the baffle 22 is also located below the right end of the left conveyor belt 1. The support plate 3 continues to flip, the support arm 5 drives the pallet 20 to continue to move, and the baffle 22 also continues to deflect. The horizontal part of the baffle 22 deflects and tilts, and as... Figure 6 In the state shown, the flipping component and the conveying component are not only away from the left conveyor belt 1, but the conveying component also deflects the baffle 22 by squeezing it, forming a heat insulation barrier on the left side of the logistics flame-retardant flipping machine, further protecting the logistics flame-retardant flipping machine.

[0063] Reference Figure 5 , Figure 7 , Figure 9 and Figure 12 The baffle 22 is provided with an auxiliary pipe 23, and multiple spray holes 24 are opened on the auxiliary pipe 23. One end of the auxiliary pipe 23 is connected to a flexible hose 25, which is laid along the base 2 and connected to the other end of the water spray pipe 15.

[0064] The auxiliary pipe 23 and the water spray pipe 15 have the same function. The water spray pipe 15 sprays water horizontally onto the right conveyor belt 1, while the auxiliary pipe 23, in conjunction with the spray nozzle 24 on it, sprays water onto the left conveyor belt 1. That is, water is sprayed onto the burning material on the right side of the logistics flame-retardant flipping machine to reduce the intensity of the open flame or inhibit its spread. The unburned goods on the left conveyor belt 1 are sprayed with water, which can effectively hinder the spread of the open flame and reduce the temperature around the open flame point, allowing on-site personnel to approach and carry out effective fire extinguishing.

[0065] Reference Figure 5 , Figure 7 , Figure 9 and Figure 12 The support arm 5 is provided with support frames 26 on both sides. Two adjacent support frames 26 are arranged in a figure-eight shape, and each support frame 26 is rotatably connected to a wheel 27 at its bottom. The wheel 27 is attached to the base 2 and rolls.

[0066] The support frame 26, in conjunction with the wheel 27, is used to enhance the stability of the support arm 5 and improve its support for the conveying component. During the flipping process of the conveying component, or when the conveying component is flipped and reset, the conveying component can return to its position and continue to be used. Even after repeated operation of the logistics flame-retardant flipping machine many times, it can still operate stably.

[0067] Reference Figure 7 , Figure 12 and Figure 13 The base 2 has a notch 28 on its upper surface, which is located on one side of the slide groove 18. A water control component is provided inside the notch 28. The water control component is installed on the water supply pipe 17 and includes a sleeve 29. Two channels 30 are radially opened on the outer wall of the sleeve 29. The channels 30 are connected to the water supply pipe 17. A sliding pin 31 is provided inside the sleeve 29. The bottom of the sliding pin 31 is connected to the bottom of the sleeve 29 by a spring 32. A through hole 33 is radially opened on the outer wall of the sliding pin 31. A ramp 34 is symmetrically provided at the upper end of the sliding pin 31, and the upper end of the sliding pin 31 protrudes from the upper surface of the base 2.

[0068] The water control component is designed for timely water spraying and cooling without requiring on-site personnel to operate water valves or other controls. The water supply pipe 17 is always connected to an open faucet. When the conveyor assembly is in a horizontal state, there is no water flow in the water supply pipe 17. When the conveyor assembly flips and moves to the right of the conveyor belt 1, the wheel 27 on the right side of the support arm 5 presses against the upper end of the sliding pin 31 and pushes the sliding pin 31 towards the bottom of the sleeve 29. At the same time, the through hole 33 on the sliding pin 31 is connected to the channel 30. At this time, the water control component is connected to the water supply pipe 17, and water flows along the water supply pipe 17 into the spray pipe 15 and the auxiliary pipe 23. The water is sprayed onto the conveyor belt 1. This design allows the logistics flame-retardant flipping machine to automatically spray water to extinguish the fire and cool down when it performs the flipping fire-retardant operation, without requiring on-site personnel to operate water valves or other controls. This quickly suppresses open flames and further reduces losses.

[0069] Reference Figure 8 The roller 11 is positioned away from the strip hole 13, and a cavity 35 is left between the roller 11 and the strip hole 13. An atomizing nozzle 16 is provided on the side wall of the cavity 35 and is used for spraying water to cool the fireproof cloth.

[0070] Atomizing nozzles 16 are also installed in the cavity 35, and the atomizing nozzles 16 at this position are connected to the water spray pipes 15 on the support plate 3 through pipes. Water is sprayed onto the fireproof cloth and flows under pressure on the surface of the fireproof cloth to cool it down, thus protecting the fireproof cloth.

[0071] Example 3:

[0072] Compared with Embodiment 1, an auxiliary support component is provided between the support plate 3 and the base 2, such as... Figure 14 and Figure 15 The structure shown is used to support the conveying assembly after it has been flipped, thereby improving the stability of the conveying assembly. Specifically, the auxiliary support assembly can be composed of a hydraulic rod 36 and a hinge seat 37. The hinge seat 37 is fixed to the base 2 and is located near the middle of the base 2. One end of the hydraulic rod 36 is rotatably connected to the hinge seat 37, and the other end of the hydraulic rod 36 is rotatably connected to the support plate 3 and is located near the support plate 3. The hydraulic rod 36 can be extended and retracted by a hydraulic pump, which is controlled by a PLC and linked to the reduction motor 6 to cooperate in flipping and supporting the conveying assembly, or to flip the conveying assembly and reset it, thereby improving the stability of the conveying assembly.

[0073] Working principle:

[0074] In the event of a fire, on the same material transport line, all the turning components are driven. The reduction motor 6 drives the support plate 3 and the conveyor belt 4 to deflect, while the screw 19 pulls the support arm 5 to move to the right. The support plate 3 flips, pulling the protective cloth out from the strip shell 10 and forming a fire barrier on the right side of the logistics flame-retardant turning machine. The support arm 5 drives the conveyor components away from the left side of the conveyor belt 1, and the baffle 22 is also squeezed and deflected by the lower edge of the other end of the support plate 3, forming a fire barrier on the left side of the logistics flame-retardant turning machine. Multiple fire barriers enhance the protection of the logistics flame-retardant turning machine and isolate burning goods.

[0075] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
