Description

Technical Field

[0001] This invention relates to the field of packaging structure technology, and in particular to a packaging device and method for finished copper tubes. Background Technology

[0002] Copper pipes, as an important type of metal pipe, are widely used in many fields such as refrigeration and air conditioning, building water supply and drainage, heat exchangers, and mechanical equipment due to their 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 step, the core purpose of which is to effectively protect the finished copper pipes during subsequent loading, unloading, warehousing, and long-distance transportation.

[0003] Copper tubes are typically packaged using a stretch wrapping machine. The machine uses a tape roll that rotates around the copper tube, continuously wrapping the packaging tape around it. This, combined with the continuous feeding of the copper tube, completes the packaging process. However, this method can only package the outer wall of the copper tube. The ends of the tube still require manual wrapping by workers or the use of caps or other structures to protect them. Therefore, the packaging of the copper tube ends cannot be automated or efficient, and it cannot be used in conjunction with a stretch wrapping machine. Summary of the Invention

[0045] In the present application, the copper pipe 4 is horizontally conveyed by a conveying wheel, a conveying belt or other conveying structure, when the copper pipe 4 passes through the winding packaging part 2 and the round hole 111 on the machine table 1, the winding packaging part 2 rotates and winds the packaging belt on the outer wall of the copper pipe, thereby realizing the packaging work of the outer wall of the copper pipe; when the copper pipe winds the packaging belt, part of the packaging belt is first wound on the support sleeve 126 outside the end of the copper pipe, and the support sleeve 126 is separated from the copper pipe while being synchronously separated from the packaging belt outside the end of the copper pipe, and the inner buckle packaging part 3 can be used to extrude the part of the excess packaging belt into the copper pipe, thereby completing the packaging work of the end of the copper pipe.

[0046] The pressing plate 321 on the inner buckle packaging part 3 can contact the outer wall of the copper pipe and extrude the packaging tape on the outer wall of the copper pipe, the top plate 323 can contact the inner wall of the copper pipe and extrude the excess packaging tape to adhere to the inner wall of the copper pipe, and the side plate 322 can contact the end of the copper pipe to facilitate the bending and shaping of the excess packaging tape at the end of the copper pipe, so that the excess packaging tape at the end of the copper pipe is extruded to protect the end of the copper pipe by the pressing groove 35 composed of the pressing plate 321, the top plate 323 and the side plate 322.

[0047] In use, the copper pipe is transversely conveyed to the position of the winding packaging part 2, the winding packaging part 2 winds the packaging tape on the copper pipe, and there is excess packaging tape extending outward at the end of the copper pipe, as the copper pipe continues to move, the winding packaging part 2 can perform winding and packaging on the outer wall of the copper pipe, and the plurality of inner buckle packaging parts 3 are initially located away from the axis of the copper pipe, when the end of the copper pipe moves to the position of the inner buckle packaging part 3, the plurality of inner buckle packaging parts 3 synchronously approach the copper pipe, the top plate 323 on the inner buckle packaging part 3 contacts the excess packaging tape at the end of the copper pipe and extrudes it towards the axis of the copper pipe, at this time the packaging tape is bent and gathered, 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 pipe, the copper pipe continues to move, and the edge position of the end of the copper pipe moves into the pressing groove 35 on the plurality of inner buckle packaging parts 3, that is, the pressing plate 321 remains outside the copper pipe and the top plate 323 is located inside the copper pipe, by the movement of the copper pipe, the excess packaging tape that is bent and gathered is extruded towards the inside of the copper pipe by the top plate 323, and the top plate 323 extrudes and adheres this part of the packaging tape to the inner wall of the copper pipe, when the end of the copper pipe contacts the side plate 322, the side plate 322 shapes and extrudes the bent position of the excess packaging tape to make it contact the edge position of the end of the copper pipe, thereby completing the packaging work on the end of the copper pipe; the plurality of inner buckle packaging parts 3 are removed, and the copper pipe continues to be conveyed, and the winding packaging part 2 can perform overall packaging on the outer wall of the copper pipe.

[0048] After the copper pipe is packaged once, it is turned over and packaged again, thereby realizing the packaging work on both ends of the copper pipe and enabling double-layer packaging on the outer wall of the copper pipe; in order to increase the extrusion area of the pressing plate 321 and the top plate 323 on the packaging tape and improve the contact rate, the working surface of the pressing plate 321 and the working surface of the top plate 323 are both set as arcs corresponding to the outer wall or the inner wall of the copper pipe; in order to increase the bending and gathering effect of the excess packaging tape by the plurality of top plates 323, the plurality of top plates 323 can be spliced into a ring shape or have small gaps between adjacent two top plates 323, so as not to cause the phenomenon that part of the packaging tape is stuck in the gap, thereby realizing overall bending of the packaging tape; the winding packaging part 2 drives the rotating ring to rotate by the power device, so that the tape installed on the rotating ring is unwound synchronously with the rotation of the rotating ring and wound on the copper pipe.

[0049] The copper pipe end is packaged by using the excess packaging belt when the copper pipe is wound and packaged, the copper pipe is fully packaged, the packaging of the copper pipe end and the packaging of the outer wall of the copper pipe are completed on one equipment, the packaging mode and the packaging steps are simplified, and the automation degree is improved. The excess packaging belt is extruded and gathered by the top plate 323 and is extruded into the copper pipe, so that the effective protection layer is formed on the copper pipe end and the copper pipe.

[0050] In the embodiment, the heat pressing structure 36 is arranged on the side of the top plate 323 facing the pressing plate 321. To improve the shaping effect of the excess packaging belt in the copper pipe and avoid the loose and stretching of the excess packaging belt outside the copper pipe due to the elasticity of the excess packaging belt, the heat pressing structure 36 is arranged on each top plate 323, as shown in Figure 3 、 Figure 4 and Figure 7 , the heat pressing structure 36 is arranged on each top plate 323, and the heat pressing structure 36 is used for heating and shaping at least part of the packaging belt on the inner wall of the copper pipe.

[0051] Specifically, the heat pressing structure 36 includes a plurality of heat pressing structures 36 arranged in pairs on the top plate 323, each heat pressing structure 36 adopts an electric heating mode, the heating surface of each heat pressing structure 36 is provided with a plurality of ribs, each pair of heat pressing structures 36 is provided with a plurality of guide columns 362 arranged obliquely, the oblique directions of the guide columns 362 on the two heat 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 through the elastic sheet 363; when the two heat pressing structures 36 in each pair move on the top plate 323, the two heat pressing structures 36 move away from or close to each other.

[0052] The heat pressing structure 36 can move obliquely on the top plate 323 by using the guide column 362, an electric heating wire or other electric heating structure can be arranged in the heat pressing structure 36, the ribs on the heat pressing structure 36 can conveniently increase the extrusion force of the heat pressing structure 36 on the packaging belt, stress concentration effect is achieved, and a plurality of pressure marks can be formed on the packaging belt; because the two heat pressing structures 36 in each pair can move relatively obliquely by using the guide column 362, when the top plate 323 pushes the plurality of heat pressing structures 36 to extrude the packaging belt in the copper pipe, the two heat pressing structures 36 in each pair can move relative to the top plate 323, that is, the two heat pressing structures 36 can move close to each other while extruding the packaging belt, so that the packaging belt is taut, and an arc-shaped hot melt strip is formed between the two heat pressing structures 36, thereby improving the shaping effect of the packaging belt; the elastic sheet 363 is mainly used for providing the heat pressing structure 36 with a reset elastic force.

[0053] In the embodiment, when the copper pipes with different wall thicknesses are packaged, the caliber of the pressing groove 35 needs to be adjustable, that is, the distance between the pressing plate 321 and the top plate 323 is adjustably arranged, so that the distance between the pressing plate 321 and the top plate 323 can be conveniently corresponding to the wall thickness of the copper pipe, and the distance between the pressing plate 321 and the top plate 323 is slightly larger than the wall thickness of the copper pipe when the pressing groove 35 is buckled at the edge position of the end of the copper pipe, so that the normal buckling is facilitated, and the assembly difficulty caused by the too small distance is avoided, and the effective extrusion on the packaging belt caused by the too large distance is avoided.

[0054] Specifically, as shown in the figure, Figure 3 The pressing plate 321 and the top plate 323 are both arranged in parallel with the axis of the round hole 111, and the side plate 322 is vertically arranged on one side of the pressing plate 321 and the top plate 323. One end of the side plate 322 is fixedly connected with the top plate 323, and the other end penetrates through the pressing plate 321 and is slidably connected with the pressing plate 321. The side plate 322 is connected with the first piston rod 311 of the first oil cylinder 31 through the transmission assembly 34. The transmission assembly 34 includes a gear 341, a first rack 342 and a second rack 343 which are in meshing transmission with the gear 341. The gear 341 is rotatably installed on the pressing plate 321. The first rack 342 and the second rack 343 are arranged in parallel on both sides of the gear 341 and are respectively installed on the first piston rod 311 and the side plate 322.

[0055] Further, as a preferred embodiment of the above, a resilient structure is further arranged between the pressing plate 321 and the top plate 323. The first piston rod 311 is connected with the pressing plate 321 through a first inserting rod 312. The first inserting rod 312 is inserted at the end of the first piston rod 311 and is slidably connected with the first piston rod 311. A baffle 313 is arranged at the end of the side plate 322 away from the top plate 323. The baffle 313 is vertically arranged with the side plate 322 and is located on the side of the gear 341 away from the pressing plate 321. The baffle 313 is connected with a first supporting plate 315 on the first piston rod 311 through a first spring 314.

[0056] In use, the first oil cylinder 31 drives the first piston rod 311 to move. The first piston rod 311 can drive the pressing plate 321 and the top plate 323 to move synchronously through the transmission assembly 34, so as to adjust the opening size of the pressing groove 35. Specifically, the first oil cylinder 31 provides power for the movement of the first piston rod 311. The gear 341 is rotatably installed on the pressing plate 321. The first piston rod 311 and the side plate 322 utilize the first rack 342 and the second rack 343 thereon to mesh with the gear 341. Therefore, when the first piston rod 311 moves relative to the pressing plate 321, the gear 341 will drive the side plate 322 to move relative to the pressing plate 321 synchronously. The moving direction of the first piston rod 311 is parallel and opposite to the moving direction of the side plate 322.

[0057] The elastic structure further limits the distance between the pressing plate 321 and the top plate 323, and at this time, the top plate 323 extrudes, bends and gathers the excess packaging belt, when the opening of the pressing groove 35 is aligned with the position of the edge of the end of the copper pipe, the end of the copper pipe is inserted into the pressing groove 35, that is, the pressing plate 321 and the top plate 323 are located on the outer side and the inner side of the copper pipe respectively, and the end face of the copper pipe abuts against the side plate 322; the first oil cylinder 31 continues to push the first piston rod 311 to move, and the pressing plate 321 abuts against the outer wall of the copper pipe, at this time, the pressing plate 321 cannot move, the first oil cylinder 31 continues to provide a pushing force for the first piston rod 311, the first piston rod 311 slides on the first inserting rod 312, at this time, the first piston rod 311 moves relative to the pressing plate 321, the first piston rod 311 can push the side plate 322 to move through the gear 341, the side plate 322 pulls the top plate 323 to move towards the inner wall of the copper pipe, so that the pressing plate 321 and the top plate 323 extrude the packaging belt at the positions of the outer wall and the inner wall of the copper pipe respectively; the use of the above structure can provide the effect of providing power for the movement and relative movement of the pressing plate 321 and the top plate 323, and the power supply is in the form of stages, so that the movement of the structure in different stages can be controlled.

[0058] 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 is connected with the first piston rod 311 through the first spring 314; by arranging the baffle 313, when the side plate 322 moves relative to the gear 341, the baffle 313 abuts against the gear 341, so as to limit the position of the side plate 322 on the pressing plate 321, that is, limit the maximum distance between the pressing plate 321 and the top plate 323, and because the side plate 322 and the first piston rod 311 are engaged with the gear 341 through the respective racks, the maximum distance between the first piston rod 311 and the pressing plate 321 can be limited, and the elastic force provided by the first spring 314 for the baffle 313 and the first piston rod 311 is matched, so that the whole structure is relatively static and complete; when the pressing plate 321 abuts against the outer wall of the copper pipe and is static, the movement of the first piston rod 311 on the first inserting 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 pressing plate 321 has been reduced, so as to realize the complete operation process of the transmission assembly 34.

[0059] In the embodiment, during the packaging of the copper pipe, after the inner buckle packaging part 3 completes the packaging of the end of the copper pipe, the inner buckle packaging part 3 needs to be removed to avoid hindering the continuous conveying and packaging of the copper pipe by the inner buckle packaging part 3, in order to achieve this purpose, the present application adopts the following structure Figure 3 and Figure 5The structure shown; the sliding seat 12 is arranged on the side of the installation vertical plate 11 provided with the inner buckle packaging part 3, the supporting sleeve 126 is arranged on the sliding seat 12, and the supporting sleeve 126 is coaxially arranged with the circular hole 111; the sliding seat 12 is arranged on the limiting frame 13 and is driven to move along the axis direction of the circular hole 111 by the pushing device 14, and the pushing device 14 is arranged on the sliding seat 12 and connected with the machine table 1. The second plug rod 332 is inserted at the end of the second piston rod 331 of the second oil cylinder 33, the second plug rod 332 is slidably connected with the second piston rod 331, and the second oil cylinder 33 is connected with the second oil cylinder 33 through the second plug rod 332; the second supporting plate 333 is arranged on the second piston rod 331, and the second supporting plate 333 is connected with the second oil cylinder 33 through the second spring 334.

[0060] Since the winding packaging part 2 needs to extend outwardly at the end of the copper pipe to wind the excess packaging belt, in order to avoid the packaging belt from being deformed due to pulling during winding, so that the excess packaging belt cannot form a cylindrical structure, a supporting sleeve 126 is added at the end of the copper pipe, as shown in Figure 5 and Figure 6 The supporting sleeve 126 is used to provide a winding position for the excess packaging belt wound outwardly at the end of the copper pipe; by using the supporting sleeve 126, the end of the packaging belt can be directly wound on the outer wall of the supporting sleeve 126, thereby providing support for the excess packaging belt, and more packaging belts can be wound in this way.

[0061] By moving the second piston rod 331 by the second oil cylinder 33, the first oil cylinder 31 can be pushed to move in the conveying direction of the copper pipe, so that when the end of the copper pipe is completely packaged, the inner buckle packaging part 3 can be separated from the end of the copper pipe by pushing the first oil cylinder 31 to move at a higher speed, and then the first piston rod 311 is pulled to retract the first oil cylinder 31 to deviate from the end of the copper pipe, thereby completing the recycling of the inner buckle packaging part 3; since the first oil cylinder 31 can slide on the second piston rod 331 through the second plug rod 332, when the copper pipe moves transversely, the end of the copper pipe can move by pushing the inner buckle packaging part 3, so that the second plug rod 332 slides on the second piston rod 331, and at this time the second spring 334 is elastically deformed. This process is mainly to make the side plate 322 contact the end of the copper pipe and maintain the contact state for a specified time, and since it is impossible to control the extension speed of the second piston rod 331 and the second oil cylinder 33 to synchronize the movement of the inner buckle packaging part 3 and the copper pipe in actual operation, the above-mentioned method can be used to complete this process.

[0062] Further, when the supporting sleeve 126 is used to support the excess packaging belt, in order to smoothly bend and deform the packaging belt by the inner buckle packaging part 3, the supporting sleeve 126 needs to be pulled away when the packaging belt is wound on the copper pipe, so as to avoid the supporting sleeve 126 from hindering the inner buckle packaging part 3, as shown in Figures 5 to 6As shown, the support sleeve 126 is arranged on the sliding seat 12 and is in sliding connection with the limiting frame 13.

[0063] Specifically, the sliding seat 12 comprises a base table 121 and a support frame 122 arranged thereon, a threaded rod 123 is arranged on the base table 121, the support frame 122 is screwed with the threaded rod 123 through a threaded sleeve 124, the threaded sleeve 124 is in rotational connection with the support frame 122; the threaded sleeve 124 is further connected with the support frame 122 through a torsion spring 125, the threaded rod 123 moves along the axis direction of the circular hole 111, and the support sleeve 126 is arranged on the support frame 122. The limiting frame 13 comprises two support vertical plates 131 arranged in parallel on both sides of the sliding seat 12, a sliding groove 132 is arranged on the support vertical plate 131, and the sliding seat 12 is in sliding connection with the sliding groove 132 through the sliding columns 127 on both sides; the sliding groove 132 comprises a horizontal section 132a and a vertical section 132b arranged vertically, the vertical section 132b extends towards the lower side of the horizontal section 132a and is located at the end of the horizontal section 132a away from the mounting vertical plate 11.

[0064] The sliding seat 12 is fixed away from the end of the copper pipe, the support vertical plates 131 are arranged on both sides of the sliding seat 12, a right-angle groove is arranged on each support vertical plate 131, one right-angle side of the right-angle groove is parallel to the conveying direction of the copper pipe, the other right-angle side of the right-angle groove extends away from the axis direction of the copper pipe, and the two sliding columns 127 are arranged in the right-angle groove in a sliding mode, the sliding columns 127 are fixed on the side wall of the sliding seat 12, and the pushing device 14 is arranged between the sliding seat 12 and the machine table 1.

[0065] The support vertical plate 131 of the limiting frame 13 is fixed on one side of the machine table 1, 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 sliding groove 132 of the support vertical plate 131, when the sliding seat 12 moves in the horizontal section 132a of the sliding groove 132 parallel to the conveying direction of the copper pipe, the support sleeve 126 moves transversely, at this time, the transverse movement speed of the support sleeve 126 is greater than the conveying speed of the copper pipe, so that the support sleeve 126 is separated from the cylinder surrounded by the excess packaging belt, and then when at least one sliding column 127 on one side of the sliding seat 12 moves into the vertical section 132b of the sliding groove 132, the sliding seat 12 and the support sleeve 126 are overturned downwards, so that the support sleeve 126 avoids the moving path of the copper pipe; the pushing device 14 can be an oil cylinder, an air cylinder, a propulsion motor or the like.

[0066] Since the support sleeve 126 needs to be separated from the cylinder surrounded by the excess packaging belt, a liquid reducing friction can be applied on the outer wall of the support sleeve 126, and when winding, part of the packaging belt can be wound on the copper pipe to avoid slipping.

[0067] Secondly, since the packaging tape output by the winding packaging part 2 needs to be wound on the support sleeve 126 at least partially firstly, the support sleeve 126 needs to move synchronously with the copper pipe to keep the butt joint state at the beginning, and the movement mode is not easy to be realized directly by the pushing device 14, so the support sleeve 126 is directly pushed to move by the conveying power of the copper pipe, at this time, the support sleeve 126 can drive the support frame 122 to slide on the base table 121, the threaded sleeve 124 moves relative to the threaded rod 123, since the threaded sleeve 124 is threadedly connected with the threaded rod 123, the threaded sleeve 124 rotates on the support frame 122, and the torsional spring 125 is elastically deformed, and when the support sleeve 126 needs to be separated from the copper pipe, the support sleeve 126 can be actively pushed to accelerate by the pushing device 14; the setting of the torsional spring 125 facilitates the resetting of the support frame 122 on the base table 121, and the structural mode can avoid occupying a large space on the base table 121, so that the space occupied by the threaded rod 123 is the maximum space allowed for the movement of the support frame 122.

[0068] The application further discloses a copper pipe finished product packaging method, characterized by adopting the copper pipe finished product packaging device, and comprising the following steps.

[0069] The copper pipe is horizontally conveyed to the machine table 1 and butts against the support sleeve 126 of the sliding seat 12 on the machine table 1.

[0070] The copper pipe drives the support sleeve 126 to pass through the round hole 111 of the machine table 1, and the packaging tape is wound on the support sleeve 126 and the copper pipe by the winding packaging part 2.

[0071] When the end of the copper pipe passes through the machine table 1, the sliding seat 12 is driven and the support sleeve 126 is separated from the end of the copper pipe.

[0072] The multiple inner buckle packaging parts 3 outside the round hole 111 drive the excess packaging tape separated from the support sleeve 126 into the copper pipe.

[0073] The other end of the copper pipe is packaged in the same way, and the packaging of the two ends of the copper pipe is completed.

[0074] In the method, the excess packaging tape is extruded by the inner buckle packaging part 3, so that the end of the copper pipe is packaged and protected, the comprehensive and automatic packaging of the end and the outer wall of the copper pipe is facilitated, and the packaging work is rapidly and continuously performed.

[0075] It should be understood by those skilled in the art that the application is not limited by the above embodiments, and the above embodiments and the description in the specification only illustrate the principles of the application, and various changes and improvements can be made to the application without departing from the spirit and scope of the application, and these changes and improvements all fall within the scope of the application.
