Description

Technical Field

[0001] This invention relates to the field of tire processing technology, and more specifically, to a front and back wrapping device and a forming machine. Background Technology

[0002] All-steel giant tires are characterized by their large size, high load-bearing capacity, numerous tire body components, and complex molding process, making it difficult to guarantee process quality. Therefore, the equipment used for the front and back wrapping of the tire body is extremely complex. Tire manufacturers frequently need to change production specifications to meet market demands. Existing molding machines require the disassembly and replacement of some tooling or the entire front and back wrapping equipment when processing different sizes of all-steel giant tires. However, due to the large size and complex structure of the equipment, the entire specification change process is time-consuming, labor-intensive, and costly, significantly impacting processing efficiency. Summary of the Invention

[0003] The main objective of this invention is to provide a reversible packaging device and a forming machine to solve the problem of time-consuming and labor-intensive process when changing specifications in existing reversible packaging devices.

[0004] To achieve the above objectives, according to one aspect of the present invention, a forward and reverse wrapping device is provided, comprising a main shaft, a booster device axially movably disposed on the main shaft, and a locking ring device connected to the booster device. The locking ring device comprises: a fixed disk connected to the booster device and axially movable relative to the booster device; a movable disk stacked on top of the fixed disk and rotatably disposed relative to the fixed disk, the fixed disk having a first groove and the movable disk having a second groove, wherein a portion of the first groove and the second groove are aligned and connected, and the other portion is offset; a plurality of bead supports passing through the first groove and the second groove, and when the movable disk rotates, the bead supports move radially under the action of the first groove and the second groove, thereby changing the diameter of the clamping area formed by each bead support; and a locking ring drive member drivenly connected to the movable disk and driving the movable disk to rotate, thereby changing the position of the bead supports.

[0005] Furthermore, both the first and second slides are inclined relative to the circumference of the movable disc, and the inclination directions of the first and second slides are opposite.

[0006] Furthermore, there are multiple first and second slides, and the first slide, the second slide, and the tire bead bracket are arranged in a one-to-one correspondence.

[0007] Furthermore, the bead support includes: a sliding shaft passing through a first groove and a second groove; a support connected to the sliding shaft and located inside the movable disc, the support moving synchronously with the sliding shaft, the support having grooves for inserting stops of different shapes, and the support also having a wear-resistant part.

[0008] Furthermore, the locking ring device also includes a locking ring drive component, which is connected to the fixed plate and drives the fixed plate to move axially.

[0009] Furthermore, the locking ring device also includes: a support shaft, which is connected to the booster device and passes through the fixed plate, the fixed plate being movably mounted on the support shaft; and a support wheel, which is connected to the fixed plate, the support wheel being located on the outer periphery of the movable plate and supporting the movable plate.

[0010] Furthermore, the booster device includes: a booster sleeve, which is sleeved on the main shaft and rotates synchronously with the main shaft; a booster cylinder, which is connected to the booster sleeve through a bearing and is capable of moving axially along the main shaft; and a booster disc, which is connected to the booster cylinder, with the booster disc and the booster sleeve located at opposite ends of the booster cylinder axially, and a locking ring device installed on the side of the booster disc facing the booster cylinder.

[0011] Furthermore, the forward and reverse packaging device also includes: a forward packaging finger device, which is housed in the booster cylinder of the booster device and is used to perform forward packaging operation; and a capsule reverse packaging device, which is housed in the booster cylinder of the booster device and is used to perform reverse packaging operation, wherein the capsule reverse packaging device is closer to the locking ring device than the forward packaging finger device.

[0012] Furthermore, both the positive packaging device and the capsule reverse packaging device include a drive connector, and the drive connector is connected to the same external drive component.

[0013] Furthermore, the positive-finger device includes: a positive-finger sleeve, which is sleeved on the main shaft and rotates synchronously with the main shaft; a positive-finger seat, which is connected to the positive-finger sleeve via a bearing; a positive-finger cylinder, which is connected to the positive-finger seat; a front pressure plate; and a rear pressure plate, which are located on opposite sides of the positive-finger seat, and the front pressure plate and the positive-finger seat are provided with elastic elements.

[0014] Furthermore, the capsule reversing device includes: a capsule reversing sleeve, which is fitted onto the main shaft and rotates synchronously with the main shaft; a rotary seal inner sleeve, which is connected to the capsule reversing sleeve; a rotary seal outer sleeve, which is connected to the rotary seal inner sleeve via a bearing; a flange, which is located on one side of the rotary seal outer sleeve; a reversing capsule, which is disposed on the outside of the rotary seal outer sleeve; a capsule support cylinder, which is disposed between the reversing capsule and the rotary seal outer sleeve; a capsule cap, which is disposed between the reversing capsule and the rotary seal outer sleeve and connected to the capsule support cylinder; and a chuck, which is disposed on the outside of the capsule support cylinder and the capsule cap.

[0015] According to another aspect of the present invention, a forming machine is provided, including the above-described positive and negative packaging device.

[0016] By employing the technical solution of this invention, a booster device and a locking device are used in conjunction. The booster device acts as the main component, while components such as the locking device are mounted on or within the booster device. Simultaneously, the booster device provides axial movement assistance, while the locking device clamps the tire bead. Specifically, the fixed and movable discs of the locking device can rotate relative to each other. Since they are respectively provided with a first and a second sliding groove, the positional relationship between the first and second sliding grooves changes when the movable disc rotates under the drive of the locking device. Because there is always a partial connection between the first and second sliding grooves, the tire bead support passing between them can move radially under the push of the first and second sliding grooves. This changes the diameter of the annular clamping area formed by the tire bead support, allowing the size of the tire bead that the locking device can clamp to be adjusted according to the specifications of the tire being processed. This achieves the clamping of tire beads of different sizes, thus enabling tire size changes without changing the tooling. Attached Figure Description

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0027] In this invention, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0028] To address the problem of time-consuming and labor-intensive specification changes in existing reversible packaging devices, this invention provides a reversible packaging device and a forming machine. The forming machine includes the following reversible packaging device.

[0029] like Figures 1 to 5The illustrated reversible packaging device includes a main shaft 10, a booster device 20 axially movably mounted on the main shaft 10, and a locking ring device 30 connected to the booster device 20. The locking ring device 30 includes a fixed disk 31, a movable disk 32, multiple bead supports 33, and a locking ring drive member 34. The fixed disk 31 is connected to the booster device 20 and is axially movable relative to the booster device 20. The movable disk 32 is stacked on top of the fixed disk 31 and is rotatably mounted relative to the fixed disk 31. The fixed disk 31 is provided with... The first slide groove and the movable disk 32 are provided with a second slide groove. Parts of the first slide groove and the second slide groove are aligned and connected, while the other part is staggered. The bead bracket 33 passes through the first slide groove and the second slide groove. When the movable disk 32 rotates, the bead bracket 33 moves radially under the action of the first slide groove and the second slide groove, and changes the diameter of the clamping area formed by each bead bracket 33. The bead locking drive member 34 is driven to connect with the movable disk 32 and drives the movable disk 32 to rotate, thereby changing the position of the bead bracket 33.

[0030] In this embodiment, the pusher device 20 and the locking device 30 are used in conjunction. The pusher device 20 serves as the main component, and the locking device 30 and other components are installed on or inside the pusher device 20. At the same time, the pusher device 20 also provides axial movement assistance, while the locking device 30 serves to clamp the tire bead. Specifically, the fixed plate 31 and the movable plate 32 of the locking ring device 30 can rotate relative to each other. Since the two are respectively provided with a first slide groove and a second slide groove, when the movable plate 32 rotates under the drive of the locking ring drive member 34, the positional relationship between the first slide groove and the second slide groove will change. Since there is always a part connecting the first slide groove and the second slide groove, the tire bead bracket 33 passing between the first slide groove and the second slide groove can move radially under the push between the first slide groove and the second slide groove, so that the diameter of the annular clamping area formed by the tire bead bracket 33 changes. In this way, the size of the tire bead that the locking ring device 30 can clamp can be adjusted according to the specifications of the processed tire, realizing the clamping of tire bead of different sizes, thereby achieving the effect of changing tire specifications without changing tooling.

[0031] like Figure 3As shown, in this embodiment, both the first and second slide grooves are inclined relative to the circumference of the movable disk 32, and their inclination directions are opposite. Specifically, the first slide groove inclines towards the center of the movable disk 32 along its circumference, while the second slide groove inclines away from the center of the movable disk 32 along the same circumference. Furthermore, their positions on the fixed disk 31 and the movable disk 32 are aligned, ensuring that a portion of the first and second slide grooves is always interconnected. As the movable disk 32 rotates, this interconnected portion changes position, causing the sidewall of the second slide groove to push the bead bracket 33, thus moving the bead bracket 33. Of course, the relative arrangement of the first and second slide grooves can be adjusted as needed, as long as their relative movement drives the bead bracket 33 to produce radial movement.

[0032] It should be noted that the movement of the bead support 33 is not entirely radial. In other words, the movement of the bead support 33 can be divided into two components: circumferential and radial. The circumferential component does not affect its operation, while the radial component is the key to clamping the bead. Therefore, as long as the bead support 33 has radial movement, the effect of clamping the bead can be achieved.

[0033] Preferably, there are multiple first and second slides, and multiple bead supports 33 are also provided. In this embodiment, the first slides, second slides, and bead supports 33 are arranged in a one-to-one correspondence. Generally, the bead supports 33 are also arranged in a one-to-one correspondence with the positive bead fingers. Furthermore, each first slide, each second slide, and each bead support 33 is arranged at intervals along the circumference of the fixing plate 31. In this way, multiple bead supports 33 can clamp and fix the bead from multiple positions inside the bead, ensuring the clamping effect. The corresponding cooperation between the first and second slides and the bead supports 33 can ensure that each bead support 33 moves independently, which not only ensures the reliability of the movement and avoids interference between structures, but also ensures that when one or more structures fail, the other bead supports 33 can still maintain the clamping effect on the bead, improving reliability.

[0034] In this embodiment, the bead support 33 includes a sliding shaft 331 and a support 332. The sliding shaft 331 is a pin and passes through a first and a second sliding groove. The support 332 is connected to the sliding shaft 331 and is located inside the movable disc 32. The support 332 moves synchronously with the sliding shaft 331. The sliding shaft 331 cooperates with the first and second sliding grooves. When the movable disc 32 rotates, the second sliding groove pushes the sliding shaft 331 by compression, changing the position of the bead support 33. The support 332 cooperates with the bead to clamp and fix it. In this embodiment, the support 332 has a groove, which can be fitted with blocks of different shapes to accommodate different shapes of steel wire bead. The support 332 also has a wear-resistant part to reduce wear. Under the drive of the bead locking drive 34, the bead support 33 can achieve the function of correcting the bead by pressing it with a finger.

[0035] In this embodiment, the bead-locking device 30 further includes a bead-locking drive 35, which is connected to the fixed plate 31 and drives the fixed plate 31 to move axially. Both the bead-locking drive 35 and the bead-locking drive 34 in this embodiment are cylinders, but other components can also be used. The bead-locking device 30 in this embodiment also includes multiple cylinder supports 38. For the bead-locking drive 34, it cooperates with two cylinder supports 38. One cylinder support 38 is connected to the fixed plate 31, and the cylinder body of the bead-locking drive 34 is pivotally mounted on this cylinder support 38. The other cylinder support 38 is connected to the movable plate 32, and the cylinder rod of the bead-locking drive 34 is pivotally mounted on this cylinder support 38. Thus, when the cylinder is actuated, the extension and retraction of the cylinder rod can drive the movable plate 32 to rotate through the cylinder support 38, achieving radial movement of the bead bracket 33. As for the bead-locking drive component 35, it can be mounted on the booster device 20 via a cylinder support 38. The cylinder rod of the bead-locking drive component 35 is connected to the fixed plate 31. Thus, when the bead-locking drive component 35 moves, the extension and retraction of the cylinder rod enables the overall axial movement of the fixed plate 31, the movable plate 32, the bead bracket 33, and other components. The reason why the bead-locking drive component 34 needs to cooperate with the fixed plate 31 and the movable plate 32 via a cylinder support 38 is that there is relative rotation between the fixed plate 31 and the movable plate 32. Therefore, the bead-locking drive component 34 needs to be pivotally connected to the cylinder support 38, while the bead-locking drive component 35 only drives the fixed plate 31 to move, so it can cooperate directly with the fixed plate 31. Of course, the bead-locking drive component 34 can also be a guide cylinder, which directly drives the bead bracket 33 to achieve the movement of the bead bracket 33.

[0036] In this embodiment, since the fixed disk 31 is axially movable, the locking ring device 30 also includes a support shaft 36. The support shaft 36 is fixedly connected to the booster device 20. The outer edge of the fixed disk 31 has a lug with a through hole. The support shaft 36 passes through the through hole. Preferably, multiple support shafts 36 are provided and spaced apart along the circumference of the fixed disk 31. In this way, the fixed disk 31 can be axially movable on the support shaft 36. When the locking ring drive 35 drives the fixed disk 31 to move axially, the locking ring device 30 can move axially as a whole. The locking ring device 30 also includes support wheels. The support wheels are rotatably connected to the fixed disk 31 and are located on the outer periphery of the movable disk 32. Multiple support wheels are also provided. The movable disk 32 is disposed between the support wheels and supported on the support wheels. In this way, the support wheels not only support the movable disk 32, but also allow the movable disk 32 to rotate smoothly relative to the fixed disk 31.

[0037] like Figure 2 As shown, in this embodiment, the booster device 20 includes a booster sleeve 21, a booster cylinder 22, and a booster disk 23. The booster sleeve 21 is fitted onto the main shaft 10. The booster sleeve 21 may be equipped with components such as keys, which cooperate with the main shaft 10 to achieve synchronous rotation. The booster cylinder 22 is connected to the booster sleeve 21 via a bearing 60. Thus, when the main shaft 10 rotates, it only drives the booster sleeve 21 to rotate; the booster cylinder 22 and its components do not rotate. The axis of the booster cylinder 22 coincides with the axis of the main shaft 10, and it can also move along the axial direction of the main shaft 10 to achieve the boosting effect. The booster plate 23 is fixedly connected to the booster cylinder 22, and the booster plate 23 and the booster sleeve 21 are located at the two ends of the booster cylinder 22 in the axial direction, respectively. The locking ring device 30 is installed on the side of the booster plate 23 facing the inside of the booster cylinder 22. The support shaft 36 and the locking ring drive 35 of the locking ring device 30 are installed on the end face of the booster plate 23.

[0038] In this embodiment, the booster sleeve 21 is smaller in size because it cooperates with the main shaft 10, while the booster cylinder 22 is larger in size. The booster sleeve 21 is located inside the booster cylinder 22 and at the end of the booster cylinder 22. This ensures that the booster device 20 is installed on the main shaft 10, while avoiding the booster sleeve 21 occupying too much space inside the booster cylinder 22, thus ensuring the installation space for other components.

[0039] like Figure 1 As shown, in this embodiment, the forward and reverse packaging device further includes a forward packaging finger device 40 and a capsule reverse packaging device 50. The forward packaging finger device 40 is housed in the booster cylinder 22 of the booster device 20 and is used to perform forward packaging operations. The capsule reverse packaging device 50 is housed in the booster cylinder 22 of the booster device 20 and is used to perform reverse packaging operations. The capsule reverse packaging device 50 is closer to the locking ring device 30 than the forward packaging finger device 40.

[0040] The booster cylinder 22 in this embodiment includes two parts: a first cylinder and a second cylinder. The first cylinder and the second cylinder are coaxially and fixedly connected. This facilitates separate processing and also facilitates assembly operations such as installing the positive-encapsulation device 40 and the capsule reverse-encapsulation device 50 into the booster cylinder 22.

[0041] like Figure 4 As shown, in this embodiment, the positive finger device 40 includes components such as a positive finger sleeve 41, a positive finger seat 42, a positive finger cylinder 43, a front pressure plate 44, a rear pressure plate 45, and a positive finger drive connector 47. The positive finger sleeve 41, similar to the booster sleeve 21, is also sleeved on the main shaft 10 and rotates synchronously with the main shaft 10 via a key. The positive finger seat 42, similar to the booster sleeve 21, is connected to the positive finger sleeve 41 via a bearing 60. Thus, when the main shaft 10 rotates, only the positive finger sleeve 41 rotates; the positive finger seat 42 and its components do not rotate. The positive finger seat 42 is a plate-shaped piece with its surface perpendicular to the main shaft 10. The positive finger cylinder 43 is connected to the positive finger seat 42 and is located on the side of the positive finger seat 42 away from the booster sleeve 21. The axis of the positive finger cylinder 43 coincides with the axis of the main shaft 10, and the size of the positive finger cylinder 43 is smaller than that of the booster cylinder 22. A front pressure plate 44 and a rear pressure plate 45 are respectively provided on opposite sides of the positive wrapping finger seat 42. Both the front pressure plate 44 and the positive wrapping finger seat 42 are provided with elastic members 46. The positive wrapping finger drive connector 47 is a component that cooperates with the external drive component of the positive wrapping finger device 40. The external drive component drives the positive wrapping finger device 40 to move through the positive wrapping finger drive connector 47, thereby cooperating with the booster device 20 and other components to achieve the positive wrapping action of the tire carcass components such as the cord fabric.

[0042] like Figure 5As shown, in this embodiment, the capsule reversing device 50 includes a capsule reversing sleeve 51, a rotary sealing inner sleeve 52, a rotary sealing outer sleeve 53, a flange 54, a reversing capsule 55, a capsule support cylinder 56, a capsule pressure cap 57, a chuck 58, and a capsule reversing drive connector 59. The capsule reversing sleeve 51 is similar to the pusher sleeve 21, and it is fitted onto the main shaft 10 and rotates synchronously with the main shaft 10 via a key. The rotary sealing inner sleeve 52 is connected to the capsule reversing sleeve 51, and the rotary sealing outer sleeve 53 is connected to the rotary sealing inner sleeve 52 via a bearing 60. Thus, when the main shaft 10 rotates, only the capsule reversing sleeve 51 and the rotary sealing inner sleeve 52 rotate; other components do not rotate. Simultaneously, the rotary sealing inner sleeve 52 and the rotary sealing outer sleeve 53 cooperate to achieve a rotary seal. The rotary sealing outer sleeve 53 can be divided into multiple parts as needed for rotary sealing at multiple positions. The reverse-encasing capsule 55 is positioned outside the rotary sealing outer sleeve 53. The axes of the reverse-encasing capsule 55, the rotary sealing outer sleeve 53, and the rotary sealing inner sleeve 52 all coincide with the axis of the main shaft 10. The axis of the flange 54 also coincides with the main shaft 10 and is located on the side of the rotary sealing outer sleeve 53 closest to the booster sleeve 21. The rotary sealing outer sleeve 53 and the reverse-encasing capsule 55 are located on the same side of the flange 54. An air passage on the flange 54 leads into the capsule, enabling inflation into the capsule. The capsule support cylinder 56 is positioned between the reverse-encasing capsule 55 and the rotary sealing outer sleeve 53; the capsule cap 57 is positioned between the reverse-encasing capsule 55 and the rotary sealing outer sleeve 53 and is connected to the capsule support cylinder 56; the chuck 58 is positioned outside the capsule support cylinder 56 and the capsule cap 57. The capsule reversal drive connector 59 is a component that cooperates with the capsule reversal device 50 and the external drive component. The external drive component inflates the capsule through the capsule reversal device 50. The bulging capsule is pushed towards the reversal drum by the pusher plate 23, thus completing the reversal action of the tire body.

[0043] In this embodiment, the positive-finger encapsulation device 40's positive-finger drive connector 47 and the capsule reverse-encapsulation device 50's capsule reverse-encapsulation device 59 are both drive connectors. More specifically, they both use hydraulic cylinder connecting pipes, and the two drive connectors are connected to the same external drive component, which drives the operation of the two devices, the positive-finger encapsulation device 40 and the capsule reverse-encapsulation device 50, through the same external drive component.

[0044] It should be noted that "multiple" in the above embodiments refers to at least two.

[0045] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0046] 1. This solves the problem of time-consuming and labor-intensive processes when changing specifications in existing front and back packaging devices;

[0047] 2. The size of the tire bead that the locking device can hold can be adjusted according to the specifications of the tire being processed, realizing the holding of tire bead of different sizes, thus achieving the effect of changing tire specifications without changing the tooling.

[0048] 3. The booster device works in conjunction with the locking ring device, the forward and reverse packaging device, and the capsule reverse packaging device to achieve forward and reverse packaging.
