[0002] As an important metal pipe, copper pipe is widely used in many fields such as refrigeration and air conditioning, building water supply and drainage, heat exchangers, mechanical equipment, etc. due to its excellent thermal conductivity, corrosion resistance and machinability. In modern industrial production, copper pipes are usually stored and transported as finished products in specific lengths (such as straight pipes). At the end of the copper pipe production process, packaging is a crucial link. Its core purpose is to effectively protect the finished copper pipes during subsequent loading and unloading, warehousing and long-distance transportation.

[0003] The packaging of copper tubes is generally completed by a wrapping packaging machine. The tape reel on the packaging machine is rotated around the copper tube, so that the packaging tape on the tape reel is continuously wrapped around the copper tube. In conjunction with the continuous transportation of the copper tube, the packaging of the copper tube is realized. However, this packaging method can only package the outer wall of the copper tube. For the end of the copper tube, workers need to manually wrap the packaging or use structures such as buckle caps to protect the end of the copper tube. Therefore, the packaging work of the copper tube end still cannot achieve an automated and efficient packaging mode, and cannot be used in conjunction with the wrapping packaging machine.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] like Figures 1 to 8As shown, a copper tube finished product packaging device and method includes a machine 1 and a wrapping packaging part 2 and an inner buckle packaging part 3 arranged on both sides of the mounting vertical plate 11 thereof. A circular hole 111 is opened on the mounting vertical plate 11. The wrapping packaging part 2 and the inner buckle packaging part 3 are both arranged on their outer rings corresponding to the circular hole 111. The inner buckle packaging part 3 is provided with multiple circumferential portions along the circular hole 111; the inner buckle packaging part 3 includes a first oil cylinder 31 and a buckle assembly 32 arranged thereon. The buckle assembly 32 is pressed by the first oil cylinder 31 drives to move toward the axis of the circular hole 111, and the first cylinder 31 is driven to move along the axis direction of the circular hole 111 through the second cylinder 33; the buckle assembly 32 includes a pressure plate 321, a side plate 322 and a top plate 323, the pressure plate 321 is connected to the first cylinder 31, and the top plate 323 is connected to the pressure plate 321 through the side plate 322, and a pressure groove 35 is formed between the pressure plate 321, the side plate 322 and the top plate 323, and the opening of the pressure groove 35 is set toward the installation vertical plate 11.

[0023] In the present invention, the copper tube 4 is horizontally transported by a conveying wheel, a conveyor belt or other conveying structures. When the copper tube 4 passes through the winding and packaging part 2 and the circular hole 111 on the machine 1, the winding and packaging part 2 rotates and wraps the packaging tape around the outer wall of the copper tube, thereby completing the packaging work on the outer wall of the copper tube; when the packaging tape is wrapped around the copper tube, part of the packaging tape will first be wrapped around the supporting sleeve 126 outside the end of the copper tube. When the supporting sleeve 126 is detached from the copper tube, it is simultaneously detached from the packaging tape outside the end of the copper tube. The inner buckle packaging part 3 can be used to squeeze this part of the excess packaging tape into the copper tube to complete the packaging work on the end of the copper tube.

[0024] The pressure plate 321 on the inner buckle packaging part 3 can contact the outer wall of the copper tube and squeeze the packaging tape on the outer wall of the copper tube, the top plate 323 can contact the inner wall of the copper tube and squeeze the excess packaging tape to fit the inner wall of the copper tube, and the side plate 322 can contact the end of the copper tube to facilitate the bending and shaping of the packaging tape at the end of the copper tube. In this way, the pressing groove 35 composed of the pressure plate 321, the top plate 323 and the side plate 322 is used to package and protect the end of the copper tube with the excess packaging tape extending from the end of the copper tube.

[0025] When in use, the copper tube is transported horizontally to the position of the wrapping part 2, and the wrapping part 2 wraps the wrapping tape around the copper tube, and there is excess wrapping tape extending outward from the end of the copper tube. As the copper tube continues to move, the wrapping part 2 can wrap the outer wall of the copper tube. The multiple inner buckle wrapping parts 3 are initially located at a position away from the axis of the copper tube. When the end of the copper tube moves to the position of the inner buckle wrapping part 3, the multiple inner buckle wrapping parts 3 approach the copper tube synchronously, and the top plate 323 on the inner buckle wrapping part 3 will contact the excess wrapping tape at the end of the copper tube and squeeze it toward the axis of the copper tube. At this time, the wrapping tape bends and gathers, and when the opening of the pressing groove 35 composed of the pressing plate 321, the top plate 323 and the side plate 322 is aligned with the end of the copper tube When the copper tube continues to move, the edge position of the end of the copper tube moves into the pressing groove 35 on the multiple inner buckle packaging parts 3, that is, the pressing plate 321 remains outside the copper tube, and the top plate 323 is located inside the copper tube. By utilizing the movement of the copper tube, the bent and gathered excess packaging tape is squeezed toward the inside of the copper tube through the top plate 323, and the top plate 323 will squeeze this part of the packaging tape to fit the inner wall of the copper tube. When the end of the copper tube contacts the side plate 322, the side plate 322 will shape and squeeze the bent position of the excess packaging tape so that it contacts the edge position of the end of the copper tube, thereby completing the packaging work for the end of the copper tube; remove the multiple inner buckle packaging parts 3, continue to transport the copper tube, and the winding packaging part 2 can fully package the outer wall of the copper tube.

[0026] After the copper tube is packaged once, it is turned around and packaged a second time, thereby completing the packaging work on both ends of the copper tube, and double-layer packaging can be performed on the outer wall of the copper tube; in order to increase the extrusion area of ​​the pressure plate 321 and the top plate 323 on the packaging tape and improve the contact rate, the working surface of the pressure plate 321 and the working surface of the top plate 323 are both set to an arc corresponding to the outer wall or inner wall of the copper tube; in order to increase the bending and gathering effect of several top plates 323 on excess packaging tape, several top plates 323 can be spliced ​​into a ring or the gap between two adjacent top plates 323 can be made smaller, which will not cause part of the packaging tape to be stuck in the gap, thereby achieving comprehensive bending of the packaging tape; the winding packaging part 2 drives the rotating ring to rotate through the power device, so that the material tape installed on the rotating ring is synchronously unwound and wrapped around the copper tube with the rotation of the rotating ring.

[0027] By utilizing the excess packaging tape when wrapping the copper tube to package the end of the copper tube, comprehensive packaging of the copper tube is achieved, and the packaging work of the copper tube end and the packaging work of the copper tube outer wall are conveniently completed on one device, simplifying the packaging method and packaging steps, and improving the degree of automation; wherein, the top plate 323 is utilized to squeeze and gather the excess packaging tape and squeeze it into the interior of the copper tube, which can facilitate the formation of an effective protective layer at both the end and the interior of the copper tube.

[0028] In this embodiment, a hot pressing structure 36 is provided on the side of the top plate 323 facing the pressing plate 321. In order to improve the shaping effect of the excess packaging tape inside the copper tube and prevent it from loosening and re-stretching outside the copper tube due to its own elasticity, a hot pressing structure 36 can be provided on each top plate 323. Figure 3 、 Figure 4 and Figure 7 As shown, each top plate 323 is provided with a hot pressing structure 36, which is used to heat and shape at least a portion of the packaging tape on the inner wall of the copper tube.

[0029] Specifically, the hot pressing structure 36 includes a plurality of hot pressing structures 36 arranged in pairs on the top plate 323, each hot pressing structure 36 adopts electric heating, and the heating surface of each hot pressing structure 36 is provided with a plurality of ribs. The two hot pressing structures 36 in each pair are inclined with a plurality of guide columns 362, and the inclination directions of the guide columns 362 on the two hot pressing structures 36 are opposite. The guide columns 362 slide through the top plate 323, and the guide columns 362 and the top plate 323 are connected by spring clips 363; when the two hot pressing structures 36 in each pair move on the top plate 323, the two hot pressing structures 36 approach or move away from each other.

[0030] The hot pressing structure 36 can be moved obliquely on the top plate 323 using the guide column 362. An electric heating wire or other electric heating structure can be set inside the hot pressing structure 36. The ribs on the hot pressing structure 36 can conveniently increase the extrusion force of the hot pressing structure 36 on the packaging tape, achieve a stress concentration effect, and facilitate the formation of several indentations on the packaging tape; since the two hot pressing structures 36 in each pair can perform relative tilting movement through the guide column 362, when the top plate 323 pushes the several hot pressing structures 36 to extrude the packaging tape in the copper tube, the two hot pressing structures 36 in each pair can move relative to the top plate 323, that is, the two hot pressing structures 36 can approach each other while extruding the packaging tape, thereby tightening the packaging tape and forming an arc-shaped hot melt strip between the two hot pressing structures 36, thereby improving the shaping effect of the packaging tape; the spring piece 363 is mainly used to provide a reset elastic force for the hot pressing structure 36.

[0031] In this embodiment, when packaging copper tubes with different wall thicknesses, in order to facilitate the buckling of the pressing groove 35 on the inner buckle packaging part 3 at the edge position of the copper tube end, the diameter of the pressing groove 35 needs to be adjustable, that is, the distance between the pressing plate 321 and the top plate 323 can be adjusted; using this setting method, it is convenient to make the distance between the pressing plate 321 and the top plate 323 correspond to the wall thickness of the copper tube, and it is convenient to make the distance between the pressing plate 321 and the top plate 323 slightly larger than the wall thickness of the copper tube when the pressing groove 35 is buckled at the edge position of the copper tube end, thereby facilitating normal buckling, avoiding the difficulty of assembly caused by too small a distance, and avoiding the inability to effectively squeeze the packaging tape due to too large a distance.

[0032] Specifically, such as Figure 3 As shown, the pressure plate 321 and the top plate 323 are both arranged parallel to the axis of the circular hole 111, and the side plate 322 is arranged perpendicularly on one side of the pressure plate 321 and the top plate 323; one end of the side plate 322 is fixedly connected to the top plate 323, and the other end passes through the pressure plate 321 and is slidably connected thereto. The side plate 322 is connected to the first piston rod 311 of the first oil cylinder 31 via the transmission assembly 34. The transmission assembly 34 includes a gear 341 and a first rack 342 and a second rack 343 that mesh with the gear 341. The gear 341 is rotatably mounted on the pressure plate 321, and the first rack 342 and the second rack 343 are arranged parallel to each other on both sides of the gear 341 and are respectively mounted on the first piston rod 311 and the side plate 322.

[0033] Furthermore, as a preference of the above embodiment, an elastic structure is also provided between the pressure plate 321 and the top plate 323, and the first piston rod 311 is connected to the pressure plate 321 through the first insertion rod 312, and the first insertion rod 312 is inserted into the end of the first piston rod 311 and is slidingly connected thereto; a baffle 313 is provided at the end of the side plate 322 away from the top plate 323, and the baffle 313 is arranged perpendicular to the side plate 322 and is located on the side of the gear 341 away from the pressure plate 321, and the baffle 313 is connected to the first support plate 315 on the first piston rod 311 through a first spring 314.

[0034] When in use, the first oil cylinder 31 pushes the first piston rod 311 to move, and the first piston rod 311 can push the pressure plate 321 and the top plate 323 to move synchronously through the transmission assembly 34 to complete the adjustment of the opening size of the pressure groove 35; specifically, the first oil cylinder 31 provides power for the movement of the first piston rod 311, and the gear 341 is rotatably installed on the pressure plate 321. The first piston rod 311 and the side plate 322 respectively use the first rack 342 and the second rack 343 thereon to engage with the gear 341. Therefore, when the first piston rod 311 moves relative to the pressure plate 321, the gear 341 will synchronously drive the side plate 322 to move relative to the pressure plate 321, and the movement direction of the first piston rod 311 is parallel to and opposite to the movement direction of the side plate 322.

[0035] The elastic structure further limits the distance between the pressure plate 321 and the top plate 323. At this time, the top plate 323 squeezes, bends and gathers the excess packaging tape. When the opening of the pressing groove 35 is aligned with the edge of the copper tube end, the end of the copper tube will be inserted into the pressing groove 35, that is, the pressure plate 321 and the top plate 323 are located on the outside and inside of the copper tube respectively, and the end face of the copper tube abuts against the side plate 322; the first oil cylinder 31 continues to push the first piston rod 311 to move, and the pressure plate 321 abuts against the outer wall of the copper tube. At this time, the pressure plate 321 cannot move, and the first oil cylinder 31 continues to provide thrust for the first piston rod 311. When the cam 321 is in the unlocked position, the first piston rod 311 and the pressure plate 321 are in relative motion, and the first piston rod 311 can push the side plate 322 to move through the gear 341, and the side plate 322 pulls the top plate 323 toward the inner wall of the copper tube, so that the pressure plate 321 and the top plate 323 squeeze the packaging tape on the outer wall and the inner wall of the copper tube respectively; the use of the above-mentioned structural method can achieve the effect of providing power for the movement and relative movement of the pressure plate 321 and the top plate 323, and the power supply is in a staged form, which is convenient for controlling the movement of the structure at different stages.

[0036] In the specific implementation process, the baffle 313 is used to limit the position of the side plate 322 on the gear 341, and the baffle 313 and the first piston rod 311 are connected by the first spring 314; by setting the baffle 313, when the side plate 322 and the gear 341 move relative to each other, the baffle 313 and the gear 341 are abutted, thereby limiting the position of the side plate 322 on the pressure plate 321, that is, limiting the maximum distance between the pressure plate 321 and the top plate 323, and because the side plate 322 and the first piston rod 311 use their respective racks to mesh with the gear 341 , so the maximum distance between the first piston rod 311 and the pressure plate 321 can be limited, and the first spring 314 can provide an elastic force on the baffle 313 and the first piston rod 311, so that the entire structure is relatively static and complete; when the pressure plate 321 abuts against the outer wall of the copper tube and is stationary, the movement of the first piston rod 311 on the first insertion rod 312 will overcome the elastic force of the first spring 314 and push the baffle 313 and the gear 341 to separate from each other. At this time, the distance between the top plate 323 and the pressure plate 321 has been reduced, thereby realizing the complete operation process of the transmission assembly 34.

[0037] In this embodiment, during the copper tube packaging process, after the inner buckle packaging part 3 completes the packaging of the copper tube end, the inner buckle packaging part 3 needs to be removed to avoid the inner buckle packaging part 3 from hindering the continuous transportation and packaging of the copper tube. To achieve this purpose, the present invention adopts the following method: Figure 3 and Figure 5The structure shown is as follows: a sliding seat 12 is provided on one side of the mounting vertical plate 11 on which the inner buckle packaging portion 3 is provided, and a support sleeve 126 is provided on the sliding seat 12, which is coaxially arranged with the circular hole 111; the sliding seat 12 is provided on the limiting frame 13 and is driven to move along the axis of the circular hole 111 by a pushing device 14, which is provided on the sliding seat 12 and connected to the machine 1. A second insertion rod 332 is inserted into the end of the second piston rod 331 of the second oil cylinder 33, and the second insertion rod 332 is slidably connected to the second piston rod 331. The second oil cylinder 33 is connected to the second oil cylinder 33 via the second insertion rod 332; a second support plate 333 is provided on the second piston rod 331, and the second support plate 333 is connected to the second oil cylinder 33 via a second spring 334.

[0038] Since the wrapping part 2 needs to extend outwards to wrap the excess wrapping tape at the end of the copper tube, in order to prevent the excess wrapping tape from being pulled and deformed during wrapping, which causes the excess wrapping tape to be unable to form a cylindrical structure, a supporting sleeve 126 is added to the end of the copper tube. Figure 5 and Figure 6 As shown, the support sleeve 126 is used to provide a winding position for the excess packaging tape that is extended outward from the end of the copper tube; using the support sleeve 126, the end of the packaging tape can be directly wound around the outer wall of the support sleeve 126, thereby providing support for the excess packaging tape, and in this way more packaging tape can be wound.

[0039] By using the second oil cylinder 33 to push the second piston rod 331 to move, the first oil cylinder 31 can be pushed to move along the conveying direction of the copper tube. Therefore, when the end of the copper tube is completely packaged, the inner buckle packaging part 3 can be separated from the end of the copper tube by pushing the first oil cylinder 31 to accelerate the movement, and then the first oil cylinder 31 is used to pull the first piston rod 311 to contract, so that the first oil cylinder 31 deviates from the end of the copper tube, thereby completing the recovery of the inner buckle packaging part 3; since the first oil cylinder 31 can slide on the second piston rod 331 through the second insertion rod 332, when the copper tube moves laterally, the end of the copper tube can push the inner buckle packaging part 3 to move, so that the second insertion rod 332 slides on the second piston rod 331, and at this time the second spring 334 undergoes elastic deformation. This process is mainly to enable the side plate 322 to contact with the end of the copper tube and maintain the contact state for a specified time. In actual operation, it is impossible to control the extension speed of the second oil cylinder 33 and the second piston rod 331 to make the inner buckle packaging part 3 and the copper tube move synchronously, so the above method can be used to complete this process.

[0040] Furthermore, when the support sleeve 126 is used to support the excess packaging tape, in order to allow the inner buckle packaging parts 3 to smoothly bend and deform the packaging tape, it is necessary to remove the support sleeve 126 when the packaging tape is wrapped around the copper tube to avoid the support sleeve 126 from obstructing the inner buckle packaging part 3. Figures 5 and 6As shown, the support sleeve 126 is disposed on the sliding seat 12 and is slidably connected to the limiting frame 13 .

[0041] Specifically, the sliding seat 12 includes a base 121 and a support frame 122 mounted thereon. A threaded rod 123 is mounted on the base 121. The support frame 122 is screwed to the threaded rod 123 via a threaded sleeve 124, which is rotatably connected to the support frame 122. The threaded sleeve 124 is also connected to the support frame 122 via a torsion spring 125. The threaded rod 123 moves along the axis of the circular hole 111. A support sleeve 126 is mounted on the support frame 122. The limiting frame 13 includes two support vertical plates 131 arranged parallel to either side of the sliding seat 12. Slide grooves 132 are formed on the support vertical plates 131. The sliding seat 12 is slidably connected to the slide grooves 132 via slide posts 127 on either side. The slide grooves 132 include a horizontal section 132a and a vertical section 132b arranged vertically. The vertical section 132b extends downward from the horizontal section 132a and is located at the end of the horizontal section 132a away from the mounting plate 11.

[0042] A sliding seat 12 is fixed to the end away from the copper tube. Support vertical plates 131 are provided on both sides of the sliding seat 12. Each support vertical plate 131 is provided with a right-angled groove. One right-angled side of the right-angled groove is parallel to the conveying direction of the copper tube, and the other right-angled side of the right-angled groove extends in the direction away from the axis of the copper tube. Two sliding columns 127 are slidingly provided in the right-angled groove. The sliding columns 127 are fixed to the side walls of the sliding seat 12. A pushing device 14 is provided between the sliding seat 12 and the machine 1.

[0043] The support vertical plate 131 of the limit frame 13 is fixed to one side of the machine 1, and the pushing device 14 can provide power for the movement of the sliding seat 12, so that the sliding seat 12 drives the two sliding columns 127 to move in the slide groove 132 of the support vertical plate 131. When the sliding seat 12 moves in the horizontal section 132a on the slide groove 132 parallel to the copper tube conveying direction, the supporting sleeve 126 moves horizontally. At this time, the lateral movement speed of the supporting sleeve 126 is greater than the copper tube conveying speed, so that the supporting sleeve 126 is pulled out from the cylinder formed by the excess packaging tape. Then, when at least one sliding column 127 on one side of the sliding seat 12 moves into the vertical section 132b of the slide groove 132, the sliding seat 12 and the supporting sleeve 126 flip downward, thereby making the supporting sleeve 126 avoid the moving path of the copper tube; the pushing device 14 can be a structure such as an oil cylinder, an air cylinder, or a propulsion motor.

[0044] Since the support sleeve 126 needs to be pulled out of the cylinder formed by the excess packaging tape, a friction-reducing liquid can be applied to the outer wall of the support sleeve 126, and when wrapping, in order to prevent the packaging tape from slipping, part of the packaging tape can be wrapped around the copper tube.

[0045] Secondly, since the packaging tape output by the wrapping packaging unit 2 first needs to be at least partially wrapped around the support sleeve 126, the support sleeve 126 needs to move synchronously with the copper tube in the initial stage to maintain their docking state, and this movement is not easy to be directly controlled by the pushing device 14. Therefore, the transmission power of the copper tube is used to directly push the support sleeve 126 to move. At this time, the support sleeve 126 can drive the support frame 122 to slide on the base 121, and the threaded sleeve 124 moves relative to the threaded rod 123. Since the threaded sleeve 124 It is threadedly connected to the threaded rod 123, so the threaded sleeve 124 rotates on the support frame 122, and the torsion spring 125 is elastically deformed. When it is necessary to separate the support sleeve 126 from the copper tube, the pushing device 14 can be used to actively push the support sleeve 126 to accelerate the movement; the setting of the torsion spring 125 makes it convenient to reset the support frame 122 on the base 121, and this structural method can avoid occupying a large space on the base 121, so that the space occupied by the threaded rod 123 is the maximum space allowed for the support frame 122 to move.

[0046] The present invention further discloses a method for packaging finished copper tube products, which is characterized by using the above-mentioned finished copper tube packaging device, including the following steps: The copper tube is transported horizontally to the machine 1 and docked with the support sleeve 126 of the sliding seat 12 on the machine 1; The copper tube drives the support sleeve 126 through the circular hole 111 of the machine 1, and the wrapping unit 2 wraps the packaging tape around the support sleeve 126 and the copper tube; When the end of the copper tube passes through the machine 1, the sliding seat 12 is driven to separate the supporting sleeve 126 from the end of the copper tube; The multiple inner buckle packaging parts 3 on the outer ring of the driving circular hole 111 squeeze the part of the packaging tape that has separated from the supporting sleeve 126 into the interior of the copper tube; Use the same method to wrap the other end of the copper tube to complete the packaging of both ends of the copper tube.

[0047] In the above method, the inner buckle packaging part 3 is used to squeeze the excess packaging tape, thereby packaging and protecting the end of the copper tube, facilitating a comprehensive and automated packaging method for the end and outer wall of the copper tube, and realizing rapid and continuous packaging work.
