Description

Technical Field

[0001] This invention relates to the technical field of packaging equipment, and in particular to a car tire bead wire packaging mechanism. Background Technology

[0002] Bead wire is the core skeleton material for manufacturing automotive tire bead. It is usually made of continuous steel wire wound into a wire roll of a specific specification to facilitate storage, transportation and subsequent processing. In the finished product packaging stage, in order to prevent the wire roll from getting damp, oxidized, damaged or contaminated with dust during transportation and storage, a protective film needs to be wrapped around its outer surface. The quality and efficiency of the film packaging directly affect the product protection effect and the production cost of the packaging process.

[0003] Currently, the packaging of tire bead wire rolls generally adopts a tire-like winding method. Specifically, the wire roll is placed horizontally or vertically and driven to rotate around its own axis. At the same time, a film roll is installed on a rotating arm or rotating frame, which makes it revolve around the cross-section of the wire roll. Through the combined motion of rotation and revolution, the film is wound layer by layer and circle by circle around the wire roll, ultimately achieving full surface coverage.

[0004] However, when using this packaging method, the winding process is carried out one turn at a time. Each revolution of the film roll can only cover a small section of the circumference of the wire roll. For large-diameter or wide wire rolls, the number of winding turns of the film roll is even greater, resulting in slow packaging speed and affecting the overall rhythm of the production line. At the same time, this method requires simultaneous driving of the rotation of the wire roll and the revolution of the film roll. The motion mechanism is complex and requires two independent rotary drive systems and precise synchronization control devices. The equipment manufacturing cost is high and the maintenance is difficult. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides a car tire bead wire packaging mechanism, the specific technical solution of which is as follows: The present invention provides a packaging mechanism for automotive tire bead wire, comprising a tubular film for packaging a wire roll, a support structure for providing support for the wire roll, and a side-pressing structure for packaging the tubular film onto the wire roll. The side-pressure structure consists of several side-pressure groups arranged in a ring on a horizontal plane. Each side-pressure group consists of two deformation units distributed opposite each other in the vertical direction. Each deformation unit includes a side-pressure plate, a flat pressure plate, and an inner pressure plate. The side-pressure plate is used to press a first portion of the cylindrical film onto the outer ring of the wire roll. The flat pressure plate is used to press a second portion of the cylindrical film onto the end face of the wire roll. The inner pressure plate is used to press a third portion of the cylindrical film onto the inner ring of the wire roll.

[0006] Furthermore, the deformation unit also includes a support platform and a slider that is slidably disposed on the side pressure plate in the vertical direction. A rotating shaft is rotatably disposed on the slider. A gear and an adjusting arm one are disposed on the rotating shaft. A flat pressure plate is disposed on the adjusting arm one. An inner pressure plate is rotatably disposed at the end of the flat pressure plate away from the adjusting arm one. An adjusting arm two is disposed on the inner pressure plate. The adjusting arm two and the slider are rotatably connected by an inclined adjusting arm three. A side platform is provided on the side wall of the side pressure plate. The side platform is horizontally slidably disposed on the support platform. A toothed area is provided on the side platform along the vertical direction. The gear meshes with the toothed area. A connecting ring is rotatably fitted on the rotating shaft. The connecting ring is rotatably connected to the support platform through an adjusting arm.

[0007] Furthermore, the support platform is movably mounted in the vertical direction, and the position of the side platform on the side pressure plate is adjustable.

[0008] Furthermore, the inner pressure plate is composed of a short plate rotatably connected to the flat pressure plate and a plurality of pressure strips arranged on the short plate. When the two inner pressure plates on the two deformation units press the cylindrical film in the corresponding area onto the inner ring of the wire roll, the pressure strip on one deformation unit is located between two adjacent pressure strips on the other deformation unit. The end of the pressure strip away from the short plate is provided with an electric heating element for hot pressing the cylindrical film.

[0009] Furthermore, in the radial direction in which several of the side pressure groups are arranged in a ring, the two deformation units in the side pressure group are staggered, and the two side pressure plates in the side pressure group are slidably connected relative to each other, and a spring is provided between the two side pressure plates; The side pressure structure also includes a power structure for providing power to one of the side pressure plates in the side pressure assembly.

[0010] Furthermore, the power structure includes a fixed ring located outside the plurality of side pressure groups, the support platform is slidably disposed on the inner wall of the fixed ring along the axial direction of the fixed ring, and the side platform moves on the support platform along the radial direction of the fixed ring; A power ring is rotatably disposed inside the fixed ring, and the power ring is rotatably connected to the corresponding side pressure plate through an inclined connecting arm.

[0011] Furthermore, the lifting structure includes a base box, a plurality of support columns, and a support plate disposed at one end of each of the support columns. The support plate is used to lift the wire coil. The support columns are vertical, and the axes of the support columns and the wire coil are offset from each other. The other end of the support column is slidably inserted into the base box. A plurality of threaded rods coaxially disposed with each of the support columns are rotatably disposed in the base box. The ends of the threaded rods are inserted into the corresponding support columns and are threadedly connected to each other. A guide groove is provided on the outer wall of the support column. The guide groove consists of a linear groove parallel to the axis of the support column and an arc groove coaxial with the axis of the support column. A guide column is slidably disposed in the guide groove and is fixed relative to the base box.

[0012] Furthermore, a ring is provided on the top of the bottom box, and an annular groove is provided on the end face of the ring, the cross section of which is inclined toward the axis of the wire coil.

[0013] The beneficial effects of this invention are as follows: By directly wrapping a cylindrical film around the outside of the wire roll and folding it toward the wire roll using several side pressure groups, the cylindrical film can be directly wrapped around the outer ring, end face, and inner ring of the wire roll, achieving rapid and comprehensive packaging of the wire roll. This effectively simplifies the packaging method, improves work efficiency, and, due to its simple structure and operation, results in lower costs and easier maintenance. Attached Figure Description

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0017] In the description of this invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0018] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0019] like Figures 1 to 8 As shown, an automotive tire bead wire packaging mechanism of the present invention includes a tubular film 2 for packaging a wire roll 1, a lifting structure 3 for providing support for the wire roll 1, and a side pressing structure 4 for packaging the tubular film 2 on the wire roll 1. The side-pressure structure 4 is composed of several side-pressure groups 5, which are arranged in a ring on the horizontal plane. Each side-pressure group 5 is composed of two deformation units 6 that are distributed opposite each other in the vertical direction. Each deformation unit 6 includes a side-pressure plate 7, a flat pressure plate 13, and an inner pressure plate 14. The side-pressure plate 7 is used to press the first part of the cylindrical film 2 onto the outer ring of the wire roll 1. The flat pressure plate 13 is used to press the second part of the cylindrical film 2 onto the end face of the wire roll 1. The inner pressure plate 14 is used to press the third part of the cylindrical film 2 onto the inner ring of the wire roll 1.

[0020] In this invention, the diameter of the tubular film 2 is larger than the diameter of the wire roll 1. The tubular film 2 can be directly fitted onto the outside of the wire roll 1 to package it. At the same time, the tubular film 2 can be lifted and spread by an external frame, robotic arm, etc., so that the tubular film 2 can be directly fitted onto the outside of the wire roll 1 during the downward movement. The lifting structure 3 can lift and support the wire roll 1, and the side pressure structure 4 can squeeze the tubular film 2 fitted onto the outside of the wire roll 1, so that the tubular film 2 adheres to the outer ring, two end faces and the inner ring of the wire roll 1, thereby realizing the rapid and comprehensive packaging of the wire roll 1. When the side pressure structure 4 squeezes the tubular film 2, the lifting structure 3 gradually separates from the wire roll 1. At this time, the side pressure structure 4 provides support for the wire roll 1 and avoids the lifting structure 3 interfering with or hindering the packaging of the tubular film 2.

[0021] The side-pressure structure 4 can compress multiple areas in the circumferential direction of the cylindrical film 2 through several side-pressure groups 5 arranged in a ring, thereby deforming the cylindrical film 2. Since it is necessary to apply part of the cylindrical film 2 to the upper and lower end faces of the wire roll 1, two deformation units 6 can be used to form the side-pressure group 5. Each deformation unit 6 can correspond to a part of the outer ring of the wire roll 1, one end face of the wire roll 1, and a part of the inner ring of the wire roll 1. In this way, two deformation units 6 can cover all areas of the wire roll 1, which facilitates the comprehensive packaging of the wire roll 1. Since the cylindrical film 2 needs to package multiple areas of the wire roll 1, the cylindrical film 2 can be divided into two sections in the vertical direction. Each section contains three areas. The first part of each section corresponds to the outer ring of the wire roll 1, and the two first parts of the two sections can fully cover the outer ring of the wire roll 1. The second part of each section corresponds to the end face of the wire roll 1. The third part of each section corresponds to the inner ring of the wire roll 1, and the two third parts of the two sections can fully cover the inner ring of the wire roll 1.

[0022] In use, the lifting structure 3 lifts the wire roll 1, expands the tubular film 2, moves it above the wire roll 1, and then moves it downwards, so that the tubular film 2 fits over the outside of the wire roll 1, with the middle of the tubular film 2 corresponding to the outer ring of the wire roll 1. Several side pressing groups 5 are located outside the tubular film 2 and move synchronously toward the tubular film 2. The two deformation units 6 in the side pressing group 5 correspond to the upper and lower sides of the tubular film 2, respectively. The side pressing plate 7 on the deformation unit 6 can push the tubular film 2 toward the outer ring of the wire roll 1, so that the part of the tubular film 2 corresponding to the side pressing plate 7 is in contact with the outer ring of the wire roll 1. The flat pressing plate 13 on the deformation unit 6 can press the part of the tubular film 2 corresponding to the flat pressing plate 13 onto the end face of the wire roll 1. At this time, the flat pressing plate 13 and the side pressing plate 7 are in contact. The cylindrical film 2 is perpendicular to each other, and its cross-section changes from a straight line to a right angle. The inner pressure plate 14 on the deformation unit 6 can squeeze the part of the cylindrical film 2 corresponding to the inner pressure plate 14 into the inner ring of the wire roll 1 and attach it to the inner wall of the wire roll 1. At this time, the inner pressure plate 14 and the flat pressure plate 13 are perpendicular to each other, and the cross-section of the cylindrical film 2 changes from a right angle to an arc shape. The two deformation units 6 simultaneously squeeze the cylindrical film 2, so that the cylindrical film 2 fully wraps the outer ring, end face and inner ring of the wire roll 1, realizing the rapid and comprehensive packaging of the wire roll 1. It should be noted that since the cylindrical film 2 is also wrapped on the inner ring of the wire roll 1, a round hole will be left in the middle of the packaged wire roll 1. This round hole can facilitate the insertion of shaft-like structures or use the round hole to fix the wire roll 1.

[0023] By directly wrapping the tubular film 2 around the outside of the wire roll 1 and folding the tubular film 2 toward the wire roll 1 using several side pressure groups 5, the tubular film 2 can be directly wrapped around the outer ring, end face and inner ring of the wire roll 1, realizing rapid and comprehensive packaging of the wire roll 1. This effectively simplifies the packaging method and improves work efficiency. At the same time, since the structure and operation are relatively simple, the cost is low and the maintenance difficulty is small.

[0024] Furthermore, the deformation unit 6 also includes a support platform 8 and a slider 9 that is slidably disposed on the side pressure plate 7 in the vertical direction. A rotating shaft 10 is rotatably disposed on the slider 9. A gear 11 and an adjusting arm 12 are disposed on the rotating shaft 10. A flat pressure plate 13 is disposed on the adjusting arm 12. An inner pressure plate 14 is rotatably disposed at the end of the flat pressure plate 13 away from the adjusting arm 12. An adjusting arm 25 is disposed on the inner pressure plate 14. The adjusting arm 215 and the slider 9 are rotatably connected by an inclined adjusting arm 316. A side platform 17 is provided on the side wall of the side pressure plate 7. The side platform 17 is horizontally slidably provided on the support platform 8. A toothed area is provided on the side platform 17 in the vertical direction. The gear 11 meshes with the toothed area. A connecting ring 18 is rotatably fitted on the rotating shaft 10. The connecting ring 18 and the support platform 8 are rotatably connected by an adjusting arm 19.

[0025] The support platform 8 provides support for the side platform 17 and the adjusting arm 19. The side platform 17 and the side pressure plate 7 move radially along the wire coil 1. When the side pressure plate 7 moves towards the wire coil 1, it drives the slider 9 and the side platform 17 to move synchronously. Since the adjusting arm 19 pulls on the rotating shaft 10 through the connecting ring 18, the rotating shaft 10 and the slider 9 move vertically on the side pressure plate 7 as it moves. By utilizing the meshing of the gear 11 on the rotating shaft 10 with the gear teeth on the side platform 17, the gear 11 and the rotating shaft 10 rotate while following the movement of the side pressure plate 7. The rotating shaft 10 drives the flat pressure plate 13 to move towards the end face of the wire coil 1 through the adjusting arm 12. While the flat pressure plate 13 moves toward the outer ring of the wire coil 1 along with the side pressure plate 7, it rotates synchronously toward the end face of the wire coil 1. The flat pressure plate 13 gradually rotates from a vertical state to a horizontal state. When the flat pressure plate 13 and the first adjusting arm 12 rotate, the flat pressure plate 13 drives the inner pressure plate 14 to move synchronously. The second adjusting arm 15 and the third adjusting arm 16 provide reverse support to the inner pressure plate 14, so that the inner pressure plate 14 can rotate on the flat pressure plate 13. The side pressure plate 7, the flat pressure plate 13 and the inner pressure plate 14 gradually rotate from a vertical state to an arc-shaped state. The inner pressure plate 14 squeezes the corresponding part of the cylindrical film 2 into the inner ring of the wire coil 1 and applies it to the inner wall of the wire coil 1, thereby achieving full packaging of the wire coil 1.

[0026] It should be noted that, using the above structure, the movement of the side pressure plate 7 can drive the flat pressure plate 13 and the inner pressure plate 14 to move synchronously, without having to independently set up motors or other drive structures for the flat pressure plate 13 and the inner pressure plate 14 in a small space. Furthermore, the above structure offers better synchronization during operation. Figures 4 to 6 As shown, to improve the stability of driving the flat plate 13, the rotating shaft 10, gear 11, adjusting arm one 12, adjusting arm two 15, adjusting arm three 16, connecting ring 18 and adjusting arm four 19 can all be set to two.

[0027] Furthermore, the support platform 8 is vertically movable, and the position of the side platform 17 on the side pressure plate 7 is adjustable.

[0028] When packaging steel wire coils 1 of different widths, the distance between the two flat pressure plates 13 on the side pressure assembly 5 when horizontal needs to be adjustable. Using the above structure, the height of the support platform 8 and the side platform 17 can be adjusted, thereby adjusting the distance between the flat pressure plate 13 and the side pressure plate 7. The support platform 8 can only move in the vertical direction, and the side platform 17 and the side pressure plate 7 can be fastened together with bolts. When adjusting the position of the flat pressure plate 13, the bolts can be loosened and the height of the side platform 17 can be adjusted, and then the bolts can be tightened.

[0029] Furthermore, the inner pressure plate 14 is composed of a short plate 20 rotatably connected to the flat pressure plate 13 and a number of pressure strips 21 arranged on the short plate 20. When the two inner pressure plates 14 on the two deformation units 6 press the cylindrical film 2 of the corresponding area onto the inner ring of the wire coil 1, the pressure strip 21 on one deformation unit 6 is located between two adjacent pressure strips 21 on the other deformation unit 6. An electric heating element 22 for hot pressing the cylindrical film 2 is provided at the end of the pressure strip 21 away from the short plate 20.

[0030] The pressure strips 21 on the two inner pressure plates 14 are staggered, and the short plate 20 can support several pressure strips 21. When the inner pressure plate 14 squeezes part of the tubular film 2 onto the inner ring of the wire roll 1, several pressure strips 21 on the two deformation units 6 can overlap each other, thereby overlapping and pressing the two third parts of the tubular film 2. At the same time, by utilizing the overlapping arrangement of the two parts of the tubular film 2 on the inner ring of the wire roll 1, it is easy for the electric heating group 22 to heat-press them, thereby preventing the packaged tubular film 2 from loosening and falling off.

[0031] In some embodiments, to improve the tightness of the tubular film 2 wrapping the wire roll 1, the tubular film 2 and the wire roll 1 inside it can be placed in a heating device, so that the tubular film 2 can be heated, causing it to shrink and adhere to the wire roll 1.

[0032] Furthermore, such as Figure 3 As shown, in the radial direction where several side pressure groups 5 are arranged in a ring, the two deformation units 6 in the side pressure group 5 are staggered, and the two side pressure plates 7 in the side pressure group 5 are slidably connected to each other, and a spring 23 is provided between the two side pressure plates 7. The side pressure structure 4 also includes a power structure, which provides power to one of the side pressure plates 7 in the side pressure assembly 5.

[0033] Both deformation units 6 have horizontal sections on their side pressure plates 7. The two side pressure plates 7 are slidably connected to each other through the horizontal sections, and a spring 23 is connected between the two horizontal sections. When the power structure drives one deformation unit 6 to move, the deformation unit 6 pushes the other deformation unit 6 to move synchronously through the spring 23, so that the two deformation units 6 move synchronously toward the wire coil 1. Due to the staggered arrangement of the two deformation units 6, one deformation unit 6 will complete the deformation first. This deformation unit 6 can first squeeze and attach a part of the tubular film 2 onto the inner ring of the wire coil 1 to form an inner layer. After the other deformation unit 6 completes the deformation, it will also squeeze and attach the corresponding part of the tubular film 2 onto the inner ring of the wire coil 1 to form an outer layer. That is, on the inner ring of the wire coil 1, the two parts of the tubular film 2 are overlapped. This avoids the two parts of the tubular film 2 located on the inner ring of the wire coil 1 from obstructing each other when the two deformation units 6 move synchronously, thus preventing them from overlapping and causing the electric heating group 22 to be unable to heat-press the two overlapping parts of the tubular film 2.

[0034] Because the two deformation units 6 are staggered, the lower deformation unit 6 can be closer to the wire coil 1. In this way, the lower deformation unit 6 will complete the deformation first, and during its deformation process, it will support the wire coil 1. At this time, the support structure 3 can be removed, and the upper deformation unit 6 will then package the wire coil 1.

[0035] Furthermore, the power structure includes a fixed ring 24 located outside a plurality of side pressure groups 5, a support platform 8 slidably disposed on the inner wall of the fixed ring 24 along the axial direction of the fixed ring 24, and a side platform 17 moving on the support platform 8 along the radial direction of the fixed ring 24. A power ring 25 is rotatably disposed inside the fixed ring 24, and the power ring 25 is rotatably connected to the corresponding side pressure plate 7 through an inclined connecting arm 26.

[0036] The fixed ring 24 provides support and guidance for the support platform 8, which in turn provides guidance for the movement of the side pressure plate 7 and the side platform 17. The rotation of the power ring 25 can be driven by a motor. When the power ring 25 rotates, it will simultaneously push the deformation units 6 on the side pressure groups 5 away from the wire coil 1 through several connecting arms 26, thereby providing power for the sequential movement of the side pressure groups 5 and the two deformation units 6 in the side pressure groups 5.

[0037] Furthermore, the lifting structure 3 includes a base box 27, a plurality of support columns 28 and a support plate 29 disposed at one end of each support column 28. The support plate 29 is used to lift the wire coil 1. The support columns 28 are vertical and the axes of the support columns 28 and the wire coil 1 are offset from each other. The other end of the support column 28 is slidably inserted into the base box 27. A plurality of threaded rods 31 are rotatably disposed in the base box 27 and coaxially disposed with each support column 28. The ends of the threaded rods 31 are inserted into the corresponding support columns 28 and are threadedly connected to each other. A guide groove is provided on the outer wall of the support column 28. The guide groove consists of a line groove 32 parallel to the axis of the support column 28 and an arc groove 33 coaxial with the axis of the support column 28. A guide column 34 is slidably arranged in the guide groove and is fixed relative to the bottom box 27.

[0038] Several threaded rods 31 can be driven by several motors, or connected to each other by a conveyor belt and driven by a single motor. When the pallet 29 lifts the wire coil 1, the guide post 34 is located in the arc groove 33 away from the wire groove 32. If the lifting structure 3 is removed at this time, the threaded rods 31 can be rotated. Since the guide post 34 restricts the support post 28 in the vertical direction through the arc groove 33, the threaded rods 31 can drive the support post 28 to rotate. The support post 28 causes the pallet 29 to deviate from the wire coil 1. When the guide post 34 moves to the bottom of the wire groove 32 in the arc groove 33, the guide post 34 restricts the rotation of the support post 28. At this time, the threaded connection between the threaded rod 31 and the support post 28 can drive the support post 28 to move in the vertical direction, thereby moving the pallet 29 away from the wire coil 1. This provides sufficient space for the work of packaging the wire coil 1 with the tubular film 2.

[0039] The base box 27 can provide support for the above structure.

[0040] Furthermore, a ring 30 is provided on the top of the bottom box 27, and an annular groove is provided on the end face of the ring 30. The cross section of the annular groove is inclined toward the axis of the wire coil 1.

[0041] The external air pump is connected to the annular groove inside the ring body 30. When the lower deformation unit 6 in the side pressure group 5 is lifting the wire roll 1, the deformation unit 6 simultaneously pushes the cylindrical film 2 toward the axis of the wire roll 1. At this time, the airflow that is sprayed outward through the annular groove can act on this part of the cylindrical film 2, so that the cylindrical film 2 overcomes gravity and goes upward and passes through the inner circle of the wire roll 1, thereby facilitating the guidance of the cylindrical film 2.

[0042] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
