[0025] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the 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 ordinary technicians in the technical field to which this application belongs.

[0027] In the present invention, unless otherwise specified, directional words such as "up, down, top, bottom" are usually used with reference to the directions shown in the drawings, or with reference to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0028] In order to solve the problem that it is time-consuming and labor-intensive to change the specifications of the front and back packaging device in the prior art, the utility model provides a front and back packaging device and a forming machine. Among them, the forming machine has the following front and back packaging device.

[0029] like Figures 1 to 5The forward and reverse packing device shown in the figure includes a main shaft 10, a booster device 20 axially movably arranged 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, a plurality of tire bead brackets 33 and a locking ring driving member 34, the fixed disk 31 is connected to the booster device 20, and can move axially relative to the booster device 20; the movable disk 32 is overlapped with the fixed disk 31, and the movable disk 32 is rotatably arranged relative to the fixed disk 31, and the fixed disk 31 is provided with The first slide groove and the second slide groove are provided on the movable plate 32, and a part of the first slide groove and the second slide groove are aligned and connected, and the other part is staggered; the bead bracket 33 is arranged in the first slide groove and the second slide groove, and when the movable plate 32 rotates, the bead bracket 33 has radial movement under the action of the first slide groove and the second slide groove, and the diameter of the clamping area formed by each bead bracket 33 is changed. The locking ring driving member 34 is driven and connected to the movable plate 32, and drives the movable plate 32 to rotate to change the position of the bead bracket 33.

[0030] In this embodiment, the boosting device 20 cooperates with the locking ring device 30. The boosting device 20 serves as the main component, and the locking ring device 30 and other components are installed on or in the boosting device 20. At the same time, the boosting device 20 serves as a boost for axial movement, and the locking ring 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 first slide groove and the second slide groove are respectively provided on the two, when the movable plate 32 rotates under the drive of the locking ring driving member 34, the positional relationship between the first slide groove and the second slide groove will change. Moreover, since there is always a part between the first slide groove and the second slide groove that is connected, the bead bracket 33 arranged between the first slide groove and the second slide groove can produce radial movement under the push of the first slide groove and the second slide groove, so that the diameter of the annular clamping area formed by the bead bracket 33 changes. In this way, the size of the bead that can be clamped by the locking ring device 30 can be adjusted accordingly according to the specifications of the processed tire, thereby realizing the clamping of bead rings of different sizes, thereby achieving the effect of changing the tire specifications without changing the tooling.

[0031] like Figure 3As shown, in this embodiment, the first chute and the second chute are both inclined relative to the circumference of the movable disk 32, and the inclination directions of the first chute and the second chute are opposite, that is, the first chute is inclined along one direction of the circumference of the movable disk 32 toward the center of the movable disk 32, while the second chute is inclined along the same circumferential direction toward the center of the movable disk 32, and the positions of the two on the fixed disk 31 and the movable disk 32 are aligned, so that there is always a portion between the first chute and the second chute that is interconnected. As the movable disk 32 rotates, the position of the interconnected portion also changes, so that the sidewall of the second chute pushes the bead bracket 33, causing the bead bracket 33 to move. Of course, the relative arrangement between the first chute and the second chute can also be adjusted as needed, as long as the relative movement of the two can drive the bead bracket 33 to generate radial movement.

[0032] It should be noted that the movement of the bead support 33 is not a completely radial movement, that is, the movement of the bead support 33 can be divided into circumferential and radial movement components. The circumferential movement component will not affect its work, and the radial movement 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 chutes, and multiple bead supports 33 are also provided. In this embodiment, the first chutes, second chutes, and bead supports 33 are provided in a one-to-one correspondence. Generally speaking, the bead supports 33 are also provided in a one-to-one correspondence with the positive wrapping fingers. Moreover, each first chute, each second chute, and each bead support 33 are arranged at intervals along the circumference of the fixed plate 31. In this way, the multiple bead supports 33 can clamp and fix the bead from multiple positions on the inner side of the bead, ensuring the clamping effect. The corresponding coordination of the first chute, second chute, and bead support 33 ensures that each bead support 33 moves independently, which not only ensures the reliability of movement and avoids interference between structures, but also ensures that when one or more structures fail, the other bead supports 33 can still ensure the clamping effect on the bead, thereby improving reliability.

[0034] In this embodiment, the bead support 33 comprises a sliding shaft 331 and a bracket 332. The sliding shaft 331 is a pin-shaped member that passes through the first and second chutes. The bracket 332 is connected to the sliding shaft 331 and located inside the movable disk 32. The bracket 332 and the sliding shaft 331 move synchronously. The sliding shaft 331 cooperates with the first and second chutes. When the movable disk 32 rotates, the second chutes squeeze and push the sliding shaft 331, causing the bead support 333 to change position. The bracket 332 cooperates with the tire bead to secure it. In this embodiment, the bracket 332 has a groove that can be fitted with blocks of various shapes to accommodate various wire tire shapes. The bracket 332 also has a wear-resistant portion to reduce wear. Driven by the locking ring driver 34, the bead support 33 can be pressed downward to achieve the positive wrapping function.

[0035] In this embodiment, the locking ring device 30 also includes a locking ring driver 35, which is connected to the fixed disk 31 and drives the fixed disk 31 to move axially. The locking ring driver 35 and the locking ring driver 34 of this embodiment both use cylinders, but other components can also be used. The locking ring device 30 of this embodiment also includes a plurality of cylinder supports 38. For the locking ring driver 34, the locking ring driver 34 cooperates with two cylinder supports 38, one of which is connected to the fixed disk 31, and the cylinder body of the locking ring driver 34 is pivotally set on the cylinder support 38, while the other cylinder support 38 is connected to the movable disk 32, and the cylinder rod of the locking ring driver 34 is pivotally set on the cylinder support 38. In this way, when the cylinder is actuated, the telescopic movement of the cylinder rod can push the movable disk 32 to rotate through the cylinder support 38, thereby realizing the radial movement of the tire bead support 33. As for the bead driver 35, it can be mounted via a cylinder support 38 or directly on the booster device 20. The cylinder rod of the bead driver 35 is connected to the fixed plate 31. Thus, when the bead driver 35 is actuated, the cylinder rod retracts and contracts, thereby achieving axial movement of the fixed plate 31, the movable plate 32, the tire bead support 33, and other components. The locking ring driver 34 requires the cylinder support 38 to cooperate with the fixed plate 31 and the movable plate 32 because the fixed plate 31 and the movable plate 32 rotate relative to each other. Therefore, the locking ring driver 34 and the cylinder support 38 need to be pivotally connected. The bead driver 35 only drives the fixed plate 31 to move, and therefore can directly cooperate with the fixed plate 31. Of course, the locking ring driver 34 can also be a guide cylinder that directly drives the tire bead support 33 to achieve movement of the tire bead support 33.

[0036] In this embodiment, since the fixed disk 31 is axially movable as a whole, the locking ring device 30 further includes a support shaft 36, which is fixedly connected to the booster device 20. The fixed disk 31 has a lug at its outer edge, and the lug has a through hole. The support shaft 36 is inserted into the through hole. Preferably, there are multiple support shafts 36, which are spaced apart along the circumference of the fixed disk 31. In this way, the fixed disk 31 can be axially movably arranged on the support shaft 36. When the buckle driver 35 drives the fixed disk 31 to move axially, the locking ring device 30 can be moved axially as a whole. The locking ring device 30 further includes support wheels, which are rotatably connected to the fixed disk 31 and are located on the outer circumference of the movable disk 32. There are also multiple support wheels, and the movable disk 32 is arranged 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 enable the movable disk 32 to rotate smoothly relative to the fixed disk 31.

[0037] like Figure 2 As shown, in this embodiment, the boosting device 20 includes a boosting sleeve 21, a boosting cylinder 22, and a boosting plate 23. The boosting sleeve 21 is sleeved on the main shaft 10. The boosting sleeve 21 may be provided with a key and other components, and the key cooperates with the main shaft 10 to achieve the effect of synchronous rotation with the main shaft 10. The boosting cylinder 22 is connected to the boosting sleeve 21 through a bearing 60. In this way, when the main shaft 10 rotates, the main shaft 10 only drives the boosting sleeve 21 to rotate, and the boosting cylinder 22 and the components on the boosting cylinder 22 do not rotate. The axis of the boosting cylinder 22 coincides with the axis of the main shaft 10, and the boosting cylinder 22 can also move along the axial direction of the main shaft 10 to achieve a 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 respectively located at the two axial ends of the booster cylinder 22. The locking ring device 30 is installed on the side of the booster plate 23 facing the inside of the booster cylinder 22, and the support shaft 36 and the buckle ring drive member 35 of the locking ring device 30 are installed on the end face of the booster plate 23.

[0038] Since the booster sleeve 21 of this embodiment cooperates with the main shaft 10, the booster sleeve 21 is smaller in size, 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. In this way, it is ensured that the booster device 20 is installed on the main shaft 10, and the booster sleeve 21 is prevented from occupying too much space in the booster cylinder 22, thereby ensuring the installation space of other components.

[0039] like Figure 1 As shown, in this embodiment, the forward and reverse packaging device also includes a forward packaging finger device 40 and a capsule reverse packaging device 50. The forward packaging finger device 40 is accommodated in the booster cylinder 22 of the booster device 20 and is used to perform the forward packaging operation; the capsule reverse packaging device 50 is accommodated in the booster cylinder 22 of the booster device 20 and is used to perform the reverse packaging operation. Compared with the forward packaging finger device 40, the capsule reverse packaging device 50 is closer to the locking ring device 30.

[0040] The booster cylinder 22 of this embodiment includes two parts, a first cylinder and a second cylinder, and the first cylinder and the second cylinder are coaxially fixedly connected. This makes it convenient to process them separately and to install the forward-wrapping finger device 40 and the capsule reverse-wrapping device 50 into the booster cylinder 22 and other assembly operations.

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

[0042] like Figure 5As shown, in this embodiment, the capsule reverse packaging device 50 includes a capsule reverse packaging sleeve 51, a rotary seal inner sleeve 52, a rotary seal outer sleeve 53, a flange 54, a reversed capsule 55, a capsule support tube 56, a capsule gland 57, a chuck 58, and a capsule reverse packaging drive connector 59. The capsule reverse packaging sleeve 51, similar to the booster sleeve 21, is mounted on the main shaft 10 and rotates synchronously with the main shaft 10 via a key. The rotary seal inner sleeve 52 is connected to the capsule reverse packaging sleeve 51, and the rotary seal outer sleeve 53 is connected to the rotary seal inner sleeve 52 via a bearing 60. As a result, when the main shaft 10 rotates, only the capsule reverse packaging sleeve 51 and the rotary seal inner sleeve 52 rotate, while other components do not rotate. The rotary seal inner sleeve 52 and the rotary seal outer sleeve 53 cooperate to achieve a rotary seal. The rotary seal outer sleeve 53 can be divided into multiple parts as needed to provide rotary sealing at multiple locations. The inverted capsule 55 is positioned outside the rotary seal outer sleeve 53. The axes of the inverted capsule 55, the rotary seal outer sleeve 53, and the rotary seal 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 seal outer sleeve 53 near the booster sleeve 21. The rotary seal outer sleeve 53 and the inverted capsule 55 are located on the same side of the flange 54. An air passage on the flange 54 allows air to enter the capsule, allowing air to be inflated. The capsule support tube 56 is positioned between the inverted capsule 55 and the rotary seal outer sleeve 53; the capsule gland 57 is positioned between the inverted capsule 55 and the rotary seal outer sleeve 53 and connected to the capsule support tube 56; and the chuck 58 is positioned outside the capsule support tube 56 and the capsule gland 57. The capsule reverse packing drive connector 59 is a component that cooperates with the capsule reverse packing device 50 and the external drive component. The external drive component inflates the capsule through the capsule reverse packing device 50. The raised capsule is pushed toward the reverse packing drum under the push of the booster disk 23 to complete the carcass reverse packing action.

[0043] The positive finger driving connector 47 of the positive finger device 40 and the capsule reverse driving connector 59 of the capsule reverse device 50 of this embodiment are both driving connectors, more specifically, both adopt oil cylinder connecting pipes, and the two driving connectors are connected to the same external driving component, and the actions of the positive finger device 40 and the capsule reverse device 50 are driven by the same external driving component.

[0044] It should be noted that, in the above embodiments, a plurality refers to at least two.
