Description

Technical Field

[0001] This application relates to the field of pipe packaging technology, and in particular to a pipe packaging device. Background Technology

[0002] Large pipes present numerous challenges during transportation due to their size and weight. To address this issue, a method of stacking and packaging pipes directly after production has been adopted, thereby reducing inconvenience in the transportation process. Therefore, the stacking platform must be lower than the conveying device to facilitate the delivery of pipes and form an assembly line. Consequently, the stacking platform cannot be equipped with a lifting device at the bottom; otherwise, the entire assembly line would need to be raised, making it inconvenient for workers to operate.

[0003] Therefore, we use a lever device on the side of the stacking platform to control the lifting and lowering of the stacking platform. However, when the stacking platform is lowered, its center of gravity will shift to the left, causing the center of gravity of the stacking platform with the pipes placed on it to shift to the left, which is dangerous.

[0004] Therefore, we need a pipe packing device that can solve the problem that the existing stacking platform tilts to the right when it descends. Summary of the Invention

[0005] The purpose of this application is to provide a pipe packing device that can solve the problem that existing stacking platforms tend to tilt to the right when descending.

[0006] To achieve the above objectives, the embodiments of this application adopt the following technical solution: a pipe packaging device, including a feeding rack and a conveying device, a stacking rack is provided on the side of the feeding rack, a pressure plate is provided on the inner side of the stacking rack, multiple sets of parallel elastic elements are provided at the bottom of the pressure plate, and a stacking platform is provided at the front end of the stacking rack; a connecting shaft is provided at the rear end of the stacking platform, the connecting shaft is used to connect the two sides of the stacking platform, an annular sleeve is provided inside the connecting shaft, and a protrusion is provided on both sides of the annular sleeve. A steel cable hole is provided at the front end of the protrusion, a steel wire rope is passed through the steel cable hole, and a counterweight is connected to the steel wire rope. A gap is opened at the front end of the protrusion with the center of the steel cable hole as the boundary, and an elastic element is provided between the gaps. The protrusion is engaged with both sides of the stacking rack, and a second protrusion is provided in the middle of the annular sleeve. The second protrusion is engaged with the inner side of the stacking rack; when the stacking platform moves down and is pressed, the stacking platform tilts to the right and downward, causing the steel cable hole at the front end of the protrusion to close, and the left and right pressures are balanced by the counterweight. At the same time, the second protrusion contacts the pressure plate and further transmits the pressure to the elastic element, further maintaining the left and right balance.

[0007] In the above technical solution, this embodiment of the application achieves the following: when the stacking platform moves downward and is compressed, it tilts downward to the right, causing the left-side protrusion one to move to the left and press against the elastic element. This closes the steel cable hole at the front end of the protrusion one, compressing the steel wire rope and linking it with the counterweight to balance the left and right pressures. When the pressure on the left side further increases, the protrusion two contacts the pressure plate and further transmits the pressure to the elastic element, further maintaining left and right balance. This solves the problem of existing stacking platforms tilting to the right during descent, achieving the effect of preventing the stacking platform from tilting to the right during descent.

[0008] Furthermore, according to the embodiments of this application, the feeding rack is provided with a drive shaft, a motor, a drive chain, and a conveyor chain.

[0009] Furthermore, according to the embodiments of this application, there are two conveyor chains, which are respectively arranged on both sides of the feeding rack.

The conveyor chains are arranged in double layers, and the rolling shafts on the double-layer conveyor chains are staggered. The two ends of the conveyor chains are connected by a gear, and the gear drives the conveyor chains to move.

[0010] Furthermore, according to the embodiments of this application, both ends of the transmission shaft one are connected to the conveyor chain, one end of the transmission shaft one is provided with a gear two, the gear two is connected to the transmission chain one, the other end of the transmission chain one is connected to a motor one, the motor one is located on one side of the feeding rack, the motor one drives the transmission chain one to drive, thereby controlling the rotation of the transmission shaft one, and driving the conveyor chain to move through the transmission shaft one.

[0011] Further, according to an embodiment of this application, the conveying device includes:

[0012] The mobile frame is square, with placement frames at both ends. The placement frames are made of square tubes and are used to place the tubes.

[0013] The movable guide rail is located at the bottom of the movable frame and extends outward from the front end of the feeding frame.

[0014] The limiting assembly has two components, which are located on both sides of the movable frame. Each limiting assembly consists of a rotating seat, a rotating shaft, and a limiting rod. There are two rotating seats, and the two ends of the rotating shaft are movably connected to the rotating seats. The limiting rods are located at both ends of the rotating shaft.

[0015] Furthermore, according to an embodiment of this application, the movable frame is also provided with four rollers, which are cylindrical and have annular notches for placing a movable guide rail. The rollers move along the movable guide rail.

[0016] Furthermore, according to the embodiments of this application, a second transmission shaft is provided between the rollers, and the two ends of the second transmission shaft are connected to the rollers at opposite ends. A third gear is provided on the second transmission shaft, and the third gear is connected to a second transmission chain. The other end of the second transmission chain is connected to a second motor, which is mounted on a movable frame. The rotation of the second motor drives the second transmission chain, thereby controlling the rotation of the second transmission shaft, which in turn drives the rollers to move along the movable guide rail, thus controlling the conveying device to move closer to or away from the feeding frame.

[0017] Furthermore, according to an embodiment of this application, the stacking platform is hollow, with openings at the top and bottom, the front end of the stacking frame passing through the openings, and the rear end of the stacking platform being inserted into the stacking frame and connected to a hydraulic push rod.

[0018] Furthermore, according to the embodiments of this application, the front end of the stacking table is provided with a through groove, and movable plates are provided on both sides of the groove. The movable plates are attached to both sides of the stacking rack and the stacking table. The movable plates are Z-shaped, with one end of the movable plate movably connected to the stacking rack and the other end set on the groove. The movable plates are connected to each other by rollers.

[0019] Compared with existing technologies, this application has the following advantages: This application employs a pipe packing device. When the stacking platform moves downward under pressure, it tilts downward to the right, causing the left-side protrusion one to move to the left and press against the elastic element. This closes the steel cable hole at the front end of the protrusion one, compressing the steel wire rope and balancing the left and right pressures in conjunction with the counterweight. When the pressure on the left side further increases, the protrusion two contacts the pressure plate and further transmits the pressure to the elastic element, further maintaining left and right balance. This solves the problem of existing stacking platforms tilting to the right during descent, achieving the effect of preventing the stacking platform from tilting to the right during descent.

[0037] like Figure 1-11As shown, this application discloses a pipe packaging device, including a feeding rack 1 and a conveying device 3. The feeding rack 1 has a stacking rack 21 on its side, and a pressure plate 211 on the inner side of the stacking rack 21. Multiple sets of parallel elastic elements 212 are provided at the bottom of the pressure plate 211. A stacking platform 22 is provided at the front end of the stacking rack 21. A connecting shaft 221 is provided at the rear end of the stacking platform 22, connecting the two sides of the stacking platform 22. An annular sleeve 222 is provided inside the connecting shaft 221. Protrusions 223 are provided on both sides of the annular sleeve 222. A steel cable hole is provided at the front end of each protrusion 223, and a steel wire rope 224 is threaded through the steel cable hole. A counterweight 225 is connected. The front end of the first protrusion 223 opens with a gap at the center of the steel cable hole. An elastic element 226 is set between the gaps. The first protrusion 223 is inserted into both sides of the stacking frame 21. The annular sleeve 222 has a second protrusion 227 in the middle, which is inserted into the inside of the stacking frame 21. When the stacking platform 22 moves down and is compressed, the stacking platform 22 tilts to the right and downward, causing the steel cable hole at the front end of the first protrusion 223 to close. The counterweight 225 is used to balance the left and right pressure. At the same time, the second protrusion 227 contacts the pressure plate 211 and further transmits the pressure to the elastic element 212, further maintaining the left and right balance.

[0038] The feeding rack 1 is equipped with a drive shaft 11, a motor 12, a drive chain 13, and a conveyor chain 14. There are two conveyor chains 14, which are respectively arranged on both sides of the feeding rack 1. Each link of the conveyor chain 14 is equipped with a rolling shaft at its top. The conveyor chains 14 are arranged in a double-layer superimposed configuration, and the rolling shafts on the conveyor chains 14 are staggered. The two ends of the conveyor chains 14 are connected by a gear 15, which drives the conveyor chains 14 to move materials. Both ends of the drive shaft 11 are connected to the conveyor chain 14. The drive shaft 11 is equipped with a gear 15, which drives the gear 15 to rotate, thereby controlling the movement of the conveyor chain 14. One end of the drive shaft 11 is equipped with a gear 16, which is connected to the drive chain 13. The other end of the drive chain 13 is connected to a motor 12, which is located on one side of the feeding rack 1. The motor 12 drives the drive chain 13 to rotate, thereby controlling the rotation of the drive shaft 11, which in turn drives the movement of the conveyor chain 14. The feeding rack 1 is also equipped with a feeding device 6, which transports the pipes to the top of the feeding rack 1 and drops them onto the feeding rack 1 to complete the feeding process.

[0039] The conveying device 3 includes: a movable frame 36, which is square and has placement frames 37 at both ends. The placement frames 37 are constructed of square tubes and are used to place pipes; a movable guide rail 38, which is located at the bottom of the movable frame 36 and extends outward from the front end of the feeding frame 1; and two limiting components 31, which are located on both sides of the conveying device 3. Each limiting component 31 consists of a rotating seat 32, a rotating shaft 33, and a limiting rod 34. The rotating seat 32 has two rotating seats, and the two ends of the rotating shaft 33 are movably connected to the rotating seats 32. The limiting rod 34 is located at both ends of the rotating shaft 33, and the bottom of the rotating shaft 33 is movably connected to a hydraulic push rod 35. The movable frame 36 is also equipped with four rollers 361, which are cylindrical and have annular notches for placing the movable guide rails 38. The rollers 361 move along the movable guide rails 38. A second drive shaft 362 is installed between the rollers 361. Both ends of the second drive shaft 362 are connected to the opposite rollers 361. A third gear 363 is installed on the second drive shaft 362, and the third gear 363 is connected to a second drive chain 364. The other end of the second drive chain 364 is connected to a second motor 365, which is mounted on the moving frame 36. The rotation of the second motor 365 drives the second drive chain 364, thereby controlling the rotation of the second drive shaft 362. This causes the rollers 361 to move along the moving guide rail 38, controlling the conveying device 3 to move closer to or further away from the feeding rack 1. An adjusting element 39 can also be installed on the limiting component 31 to adjust its length, allowing for flexible adjustment of the packaging area when packaging a large quantity.

[0040] The stacking rack 21 is also equipped with a pulley assembly 228, which is located in the upper right corner of the stacking rack 21. The pulley assembly 228 contains three pulleys, two of which can form a force-saving pulley. A counterweight 225 is set below the force-saving pulley, so that the downward gravity of the counterweight 225 is converted into a pulling force to the upper right. Then, a pulley is set on the right side, which converts the pulling force to the upper right into a downward pulling force. The pulley assembly 228 is connected by a steel wire rope 224. The steel wire rope 224 is set downward along the stacking rack 21 through the pulley assembly 228 and fixed to the bottom of the stacking rack 21 to keep the steel wire rope 224 taut. In order to prevent dirt and dust from interfering, a cover can be put on the outside of the pulley assembly 228, and a groove can be set to allow the counterweight 225 to move up and down, thereby limiting the range of movement of the counterweight 225, protecting the structure and preventing danger.

[0041] The stacking table 22 is hollow, with openings at the top and bottom. The front end of the stacking frame 21 passes through the openings, and the rear end of the stacking table 22 is inserted into the stacking frame 21 and connected to the hydraulic push rod 23. The front end of the stacking table 22 has a through groove, and movable plates 24 are provided on both sides of the groove. The movable plates 24 are attached to the sides of the stacking frame 21 and the stacking table 22. The movable plates 24 are Z-shaped, with one end movably connected to the stacking frame 21 and the other end set on the groove. The movable plates 24 are connected to each other by rollers 25.

[0042] The bottom of the stacking device 2 is provided with a horizontal groove 4, which is lower than the plane of the conveying device 3. The stacking platform 22 can be lowered to the bottom of the horizontal groove 4. After stacking is completed, the stacking device 2 can be controlled to move to the bottom horizontal groove 4. At this time, the pipes that were originally placed on the stacking platform 22 lose the support of the stacking platform 22 and are placed on the placement frame 37 of the conveying device 3, so that the pipes are separated from the stacking device 2 for easy movement. Then, the pipes are moved outward to the packaging area for packaging by the conveying device 3.

[0043] The packaging platform 5 is located outside the conveyor device 3. There are two packaging platforms 5, with the conveyor device 3 positioned between them. The top of each packaging platform 5 is a square platform, and the bottom is equipped with a hydraulic device. After the pipes are stacked, the conveyor device 3 transports the pipes to the packaging area between the packaging platforms 5. Then, the hydraulic device lifts the pipes for easy packaging. After packaging, the control limit component 31 is lowered, and a crane is used to hoist the packaged pipes to the finished product stacking area. This solves the problem of traditional packaging platforms being too low, requiring workers to bend over to stack the pipes, thus affecting work efficiency. It achieves the effect of controlling the lifting and lowering of the packaging platform, allowing workers to stand while packaging.

[0044] When the stacking platform 22 is lowered and compressed, it tilts downwards to the right, causing the left-side protrusion 223 to move to the left and press against the elastic element 226. This closes the cable hole at the front end of the protrusion 223, compressing the wire rope 224 and balancing the left and right pressures in conjunction with the counterweight 225. When the pressure on the left side further increases, the protrusion 227 contacts the pressure plate 211 and further transmits the pressure to the elastic element 212, further maintaining left and right balance. This solves the problem of existing stacking platforms tilting to the right during descent, effectively preventing the stacking platform from tilting to the right during descent. Figure 11The diagram, viewed from left to right, shows the following: the first image shows the stacking platform in a horizontal position when it is located above the stacking rack, with the weight of both ends balanced; the second image shows the stacking platform tilting when it moves to the lower part of the stacking rack; the third image shows the stacking platform being balanced by protrusion 223 after tilting, at which point it is initially balanced but still slightly tilted; the fourth image shows the stacking platform being balanced by protrusions 223 and 227 together after tilting, at which point it is no longer tilted and is horizontal.

[0045] This application moves the pipes to the front end of the feeding rack 1 via the conveying device 3, and then controls the rotation of the rotating shaft 33 on the rotating seat 32 by the extension and retraction of the hydraulic push rod 35, thereby controlling the lifting of the limiting rod 34. The pipes on the feeding rack 1 are then moved to the stacking platform 22 and stacked within the range between the limiting rods 34. The hydraulic push rod 23 controls the stacking platform 22 to descend as the pipes are stacked, and after stacking, it descends to the bottom, placing the pipes on the conveying device 3 for outward transport and packaging. This solves the problem of traditional packaging platforms being too low, requiring workers to bend over to stack, thus affecting work efficiency. It achieves the effect of controlling the lifting and lowering of the packaging platform, allowing workers to stand while packaging. Example

[0046] This application also discloses a method of using a pipe packaging device, including the following steps:

[0047] The conveying process involves setting up a baffle at the end of the conveyor belt. After the pipe is transported to the end, it hits the baffle and slides down the inclined bar behind the conveyor belt onto the feeding rack 1, thereby transferring the processed pipe to the packaging step.

[0048] Preparation: The conveying device 3 moves along the moving guide rail 38 to the feeding rack 1 and moves to the stacking device 2. Then, the hydraulic push rod 35 pushes it outward to control the limiting component 31 to rotate around the rotating shaft 33, so that the limiting component 31 stands up and the moving frame 36 is perpendicular to the conveying device 3.

[0049] The pipes are stacked. When the feeding rack 1 transports the pipes to the conveying device 3, if the pipes can be lifted, the workers lift both ends of the pipes and place them in the stacking area formed between the limiting components 31. If the pipes are too heavy to be lifted, the height of the limiting component 31 on the side closer to the feeding rack 1 is adjusted so that it is lower than the stacking device 2. When stacking, the power of the feeding rack 1 is used to push both ends of the pipes by the workers, so that the pipes slide on the stacking device 2 into the limiting component 31 for stacking. At the same time as stacking, the height of the stacking device 2 is controlled so that the limiting component 31 is higher than the stacking device 2 for easy stacking.

[0050] After the required number of pipes are stacked, the stacking device 2 is lowered to the bottom. At this time, the stacking device 2 is located below the moving guide rail 38, so that the pipes are placed on the placement frame 37. Then, the conveying device 3 is moved to the outermost side, and the pipes are lifted by the packing table 5. The pipes are then packed. After packing, the limiting component 31 is rotated inward so that the limiting component 31 is parallel to the moving frame 36, thus completing the packing and allowing for hoisting and movement.
