Description

Technical Field

[0001] The invention relates to the technical field of double-pass packaging of seamless pipes, in particular to a double-pass packaging device for seamless pipes used in heat exchangers. Background Art

[0002] A baler, also known as a strapping machine, banding machine, or strapping machine, uses strapping tape to bundle products or packages, then tightens and fuses the ends together using a hot iron. The function of a baler is to reinforce packaged items to prevent them from falling apart during transportation or storage due to loose strapping. The strapping should also be neat and aesthetically pleasing. Seamless heat exchanger pipes are often packaged using baling equipment for easier handling and transportation.

[0003] There are four forms of bundled packages for seamless pipes: round, rectangular, frame and hexagonal. Among them, hexagonal packages are more stable than rectangular packages, more economical and simpler than frame packages, and more neat and beautiful than round packages. They have a larger force surface when stacked and are easy to calculate. Therefore, in actual production, some manufacturers often use hexagonal packages, especially high-quality products. The existing forming and packaging equipment uses a magnetic disk to lift seamless pipes in rows and lift them into a temporary storage rack. The seamless pipes inside the temporary storage rack are stacked in a hexagonal shape and transported to the bottom of the baler. They are then bundled and packaged by a baling mechanism, packaged by a baler, and then lifted away by a crane.

[0004] With regard to the above-mentioned related technologies, the inventors believe that, during the current packaging of seamless pipes, since no shrinking assistance is performed when the seamless pipes are transported to the interior of the packaging equipment, the seamless pipes are still in a loose state. Therefore, when subsequently packaged by the packaging equipment, the seamless pipes are in an unstable state, making it difficult for the packaging belt of the seamless pipe packaging equipment to tightly tighten the seamless pipes, thereby affecting the quality of packaging. At the same time, the existing packaging equipment only has a single-layer bundling function, and can only perform one bundling operation along the circumferential direction of the seamless pipe, and cannot realize the automatic sealing and second-stage packaging of the two ends of the seamless pipe. This single packaging mode is difficult to meet the protection requirements of the seamless pipe ends. During transportation and handling, the seamless pipe ends are prone to bump damage, port deformation and other problems due to lack of effective protection, thereby affecting the dimensional accuracy and performance of the seamless pipes. Summary of the Invention

[0005] The object of the present invention is to provide a double-pass packaging device for seamless pipes for heat exchangers, so as to solve the problem raised in the above background technology that during the current packaging of seamless pipes, since the seamless pipes are not assisted in being gathered when they are transported to the interior of the packaging equipment, the seamless pipes are still in a loose state, so that when they are subsequently packaged through the packaging equipment, the seamless pipes are in an unstable state, making it difficult for the packaging belt of the seamless pipe packaging equipment to tightly tighten the seamless pipes, thereby affecting the quality of packaging. At the same time, the existing packaging equipment only has a single-layer bundling function, and can only perform one bundling operation along the circumferential direction of the seamless pipe, and cannot realize the automatic sealing and two-pass packaging of the two ends of the seamless pipe. This single packaging mode is difficult to meet the protection requirements of the seamless pipe ends.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figure 1 - Figure 7 A double-channel packaging device for seamless pipes for heat exchangers includes a mounting frame 1, a conveyor 2 fixedly installed in the middle of the top of the mounting frame 1 through a bracket, and a temporary storage frame 3 slidably mounted on the top of the conveyor 2. Two limiting rings 4 are symmetrically arranged on both sides of the top of the mounting frame 1, and a retracting component and an end cover pressing component are provided on one side of the limiting ring 4. An adjusting component is provided on the top of the mounting frame 1; the retracting component includes a ring frame 9 and a plurality of extrusion blocks 17. The ring frame 9 is sleeved and rotatably engaged with the outside of one side of the limiting ring 4, and a plurality of extrusion blocks 17 are arranged at equal angles around the inside between the limiting ring 4 and the ring frame 9.

[0034] The adjustment component includes a bidirectional threaded rod 5 and an auxiliary rod 6. The bidirectional threaded rod 5 is rotatably installed inside the edge of one side of the mounting frame 1, and the auxiliary rod 6 is rotatably installed inside the edge of the other side of the mounting frame 1. A stepper motor 7 is fixedly installed on the outside of one side of the mounting frame 1. The output end of the stepper motor 7 is coaxially fixed with one end of the bidirectional threaded rod 5. Two limit seats 8 are symmetrically installed on both sides of the top of the bidirectional threaded rod 5 and the auxiliary rod 6. Each limit seat 8 is threadedly connected to the bidirectional threaded rod 5, and each limit seat 8 is slidably connected to the auxiliary rod 6. The top of each limit seat 8 is fixed to the bottom end of the limit ring 4 on the corresponding side.

[0035] A gear ring 10 is fixedly installed on the outside of the circular frame 9, and a limiting gear 11 is installed on the outside of the limiting seat 8 near the bottom end of the gear ring 10 through a rotating seat. One side of the limiting gear 11 is meshed with one side of the bottom end of the gear ring 10, and a rotating shaft 12 is slidably installed on the inside of the limiting gear 11. Both ends of the rotating shaft 12 are rotatably installed on the inside of the two sides of the mounting frame 1, and a driving motor 13 is fixedly installed on the outside of one side of the mounting frame 1, and the output end of the driving motor 13 is coaxially fixed with one end of the rotating shaft 12.

[0036] The outer surface of the rotating shaft 12 located inside the mounting frame 1 is fixed with several limit bars 14 at equal angles. A slide groove 15 is embedded inside the side of the limit gear 11 close to each limit bar 14, and each limit bar 14 is slidably installed inside the slide groove 15 on the corresponding side.

[0037] In this embodiment, when the double-channel packaging device for seamless pipes for heat exchangers is used, the device is first fixedly installed on the bottom of the existing packaging and bundling mechanism as a whole, and then the seamless pipes stacked on the temporary storage rack 3 are transported by the operation of the existing conveyor 2. When the temporary storage rack 3 and the seamless pipes are transported between the two limit rings 4, the conveyor 2 is controlled to stop running, and at the same time, the stepper motor 17 on one side is started. The rotation of the output end of the stepper motor 17 drives the bidirectional threaded rod 5 installed on one side to start rotating. At the same time, the auxiliary rod 6 is limited, so that the bidirectional threaded rod 5 will drive the limit seats 8 with threaded connections on both sides to start synchronous centering movement when rotating. When the limit seat 8 moves, it will drive the limit ring 4 and the ring frame 9 on one side to move synchronously. When the limit rings 4 and the ring frame 9 on both sides move centrally to the two ends of the seamless pipe, the stepper motor 7 is stopped at this time, and then the drive motor 13 is started. The rotation of the output shaft of the drive motor 13 drives the rotation of the rotating shaft 12 on one side. At the same time, the setting of the external limit strip 14 of the rotating shaft 12 and the internal slide groove 15 of the limit gear 11 makes it possible for the limit gear 11 to be driven by the rotating shaft 12 when it slides to any position on the rotating shaft 12. When the rotating shaft 12 drives the limit gear 11 to rotate, the limit gear 11 will drive the gear ring 10 meshing at the top to rotate synchronously. The rotation of the gear ring 10 drives the circular frame 9 to rotate synchronously. At this time, the guide groove 19 guides the limiting column 18 and the limiting groove 16 limits the limiting column 18, so that when the circular frame 9 rotates, it will drive several extrusion blocks 17 to move synchronously, so that the size of the regular hexagonal hollow formed by the several extrusion blocks 17 is contracted and changed, thereby forming a regular hexagonal contraction structure, so that the two ends of the seamless pipe can be sleeved, clamped and closed in the center during bundling. By implementing the closing operation on the seamless pipe, the originally loose seamless pipe can be effectively concentrated and fixed before packaging. In this way, the seamless pipe can maintain a stable state during the packaging process. , which makes it easy for the strapping equipment to tighten it tightly, thereby greatly improving the stability and quality of packaging. Through the centering clamping and gathering of this structure, the seamless tube is closer to the standard hexagonal shape after packaging, further strengthening the shape stability of the hexagonal package, making the seamless tube more stable during stacking and transportation, improving the overall efficiency and standardization of packaging, and reducing problems such as loose packaging caused by unstable seamless tubes. At the same time, the gathered seamless tube can better cooperate with the end packaging shells 23 on both sides, creating favorable conditions for the implementation of the second packaging. After the gathering is completed, the gathered seamless tube is bundled and packaged by controlling the existing packaging and strapping mechanism to descend.

[0038] Example 2: Please refer to Figure 8 - Figure 12This embodiment further explains Example 1. The end cover clamping assembly includes a fixing frame 20, a hexagonal ring 21 and a guide rail frame 28. The fixing frame 20 is fixedly mounted on the outside of the limiting ring 4 away from the temporary storage rack 3, the hexagonal ring 21 is fixedly mounted on the outside of the fixing frame 20, and the guide rail frame 28 is arranged on the outside of the side of the hexagonal ring 21 away from the limiting ring 4.

[0039] A limiting groove 16 is embedded inside the ring frame 9 at the edge of one side near the several extrusion blocks 17. The limiting groove 16 is set in a regular hexagonal shape when viewed from the front. A limiting column 18 is fixedly installed inside one end of the several extrusion blocks 17. One end of the limiting column 18 is embedded, engaged and slidably installed inside one side of the limiting groove 16. The internal hollow formed by the fit between the several extrusion blocks 17 is also set in a regular hexagonal shape.

[0040] A guide groove 19 is obliquely provided inside the circular frame 9 on one side close to the limiting column 18 , and one end of the limiting column 18 is slidably engaged with the guide groove 19 on the corresponding side.

[0041] A support bracket 22 is fixedly installed on the bottom side of the hexagonal ring 21 close to the limiting ring 4, and an end packaging shell 23 is placed on the top of the support bracket 22. A number of rubber contact heads 24 are evenly spaced inside the end packaging shell 23 close to the limiting ring 4, and a baffle 27 is fixedly installed laterally on the side of the top of the hexagonal ring 21 away from the limiting ring 4.

[0042] A rectangular placement rack 25 is longitudinally arranged through the top of the hexagonal ring 21, and end packaging shells 23 are also stacked inside the rectangular placement rack 25. A support rack 26 is fixedly installed on one side of the rectangular placement rack 25, and one end of the support rack 26 is fixedly installed on the outside of one side of the mounting rack 1.

[0043] A positioning frame 29 is fixedly installed at the initial end of the guide rail frame 28, and one end of the positioning frame 29 is fixedly installed to the outside of one side of the hexagonal ring 21. The guide rail frame 28 is arranged in a spiral shape, and a hollow seat 30 is slidingly set through the outside of one end of the guide rail frame 28. An auxiliary groove 31 is embedded inside one side of the guide rail frame 28, and a stepper motor 2 33 is fixedly installed on the outside of the hollow seat 30 close to the auxiliary groove 31. A driving wheel 32 is coaxially fixed to the output end of the stepper motor 2 33, and one end of the driving wheel 32 is rollingly engaged and installed inside one side of the auxiliary groove 31.

[0044] An electric telescopic rod 34 is fixedly mounted on one end of the hollow seat 30 close to the hexagonal ring 21 , and a limit cover 35 is fixedly mounted on the output end of the electric telescopic rod 34 . A squeezing ball 36 is rotatably mounted inside the limit cover 35 .

[0045] In this embodiment, when the limit seat 8 drives the limit ring 4 to move in the center for a retracting movement, the limit ring 4 will drive the fixed frame 20, the hexagonal ring 21 and the supporting frame 22 on one side to move synchronously. When it moves to a certain position, the end packaging shell 23 that is fitted on one side of the hexagonal ring 21 and the supporting frame 22 will come into contact with the retracted end of the seamless pipe, so that the wrapping cover end of the end packaging shell 23 can come into contact with the outside of the end of the seamless pipe, thereby realizing two-stage packaging, which provides additional protection for the end of the seamless pipe, effectively preventing the end from being damaged by collision, friction, etc. during transportation, and significantly improving the transportation safety and use effect of the seamless pipe.

[0046] It should also be noted that when the limiting ring 4 drives the one side fixing frame 20 and the hexagonal ring 21 to move to engage with the end packaging shell 23, it will drive the baffle 27 at the top to move synchronously, so that the top of the baffle 27 will engage with the bottom opening of the rectangular placement frame 25, so that the end packaging shell 23 inside the rectangular placement frame 25 will not fall. At the same time, when the limiting ring 4 drives the one side fixing frame 20 and the hexagonal ring 21 to move and reset, it will drive the baffle 27 at the top to move and reset synchronously. When the reset is completed, the baffle 27 is disengaged from the bottom opening of the rectangular placement frame 25. After that, the end packaging shell 23 inside the rectangular placement frame 25 will slide to the bottom hexagonal ring 21 and the top of the supporting frame 22 under gravity, thereby completing the automatic feeding of the end packaging shell 23, and the overall use is convenient.

[0047] It should also be noted that when the end packaging shell 23 contacts the folded end of the seamless pipe, the electric telescopic rod 34 is started and the output end of the electric telescopic rod 34 is extended, thereby driving the limit cover 35 and the squeezing ball 36 on one side to extend synchronously, so that the squeezing ball 36 contacts one of the rubber contact heads 24 inside the end packaging shell 23, thereby forcing the rubber contact head 24 into the interior of one of the seamless pipe ends, and at the same time, the stepping motor 2 33 on one side is started and the output shaft of the stepping motor 2 33 is rotated to drive the driving wheel 32 to rotate synchronously, so that the driving wheel 32 moves along the auxiliary groove 31 inside the spiral guide frame 28. The hollow seat 30 and the extended squeezing ball 36 are rolled to press against the outside of the end packaging shell 23 for orderly rotation and squeezing, so that the squeezing ball 36 can evenly roll and press against the rubber contact head 24 inside the end packaging shell 23, which enables the rubber contact heads 24 to be evenly and comprehensively stressed, and then smoothly press against the inside of several single seamless tube ends in turn, ensuring the overall docking and packaging stability of the end packaging shell 23, avoiding the end packaging shell 23 from falling off and the seamless tube end being exposed during transportation due to loose docking of the end packaging shell 23, and further enhancing the integrity and reliability of the seamless tube after packaging.

[0048] It should also be noted that when a bundle of seamless pipes is completed with double-track packaging, the electric telescopic rod 34 is controlled to be retracted, and the stepper motor 2 33 is controlled to stop, and then the stepper motor 1 7 is controlled to reverse, thereby driving the limit seat 8 and the limit ring 4 to move back and reset to separate from the packaged and bundled seamless pipes. After that, the conveyor 2 is started again to transport the packaged seamless pipes out, and at the same time, the next bundle of unpackaged seamless pipes is transported to the bottom of the packaging and bundling mechanism for circular packaging and use.
