[0021] By applying the technical solution of the present invention, the following technical effects are achieved:

[0022] 1. The layout of this application adopts a large-diameter laminating process, that is, the laminating diameter of the cord is the same as the diameter of the actual final tire body tube, and the cord has no circumferential stretching during the tire making process, and the tire cord density is high and the strength is good. Corresponding to this is a small-diameter laminating process, which is more common in the one-step process. The advantage of the small-diameter laminating process is that the current technology has a high degree of automation, but its cord has circumferential stretching, which affects the tire cord density and is lower than the tire tube strength manufactured by the large-diameter laminating process.

[0023] 2. When the size of the tire that needs to be wrapped positively and negatively changes, the expansion and contraction assembly will drive the drum plate to move along the radial direction of the inner sleeve, changing the circle formed by the drum plate along the circumference of the inner sleeve. Since the capsule is installed on the drum plate, when the diameter of the circle formed by the drum plate changes, the diameter of the capsule will also change accordingly, thereby adapting to rubbers of different sizes and being able to process tires of different sizes. There is no need to replace the capsule side drum, thereby solving the problem of time-consuming and labor-intensive replacement.

[0024] 3. Since the range of change in the stop diameter of the buckle ring assembly and the diameter of the circular ring composed of the positive and negative wrapping finger assembly is related to the radial movement of the buckle ring assembly, and the radial movement of the buckle ring is a continuous movement, it can stop at any position within its movement range under the drive of the positive and negative wrapping driving assembly. Therefore, the present application can be adapted to tires of various sizes, not limited to one or two, and has a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In order to solve the problem that the agricultural tire forming machine in the prior art cannot meet the production and processing requirements, the present invention provides an agricultural tire carcass tube production process and agricultural tire carcass tube production equipment.

[0036] Embodiment 1

[0037] See also Figures 1 to 4 A production process for a carcass tube for agricultural tires adopts production equipment for carcass tube for agricultural tires. The production equipment for carcass tube for agricultural tires includes a positive and negative packing device 5, a bladder side drum 6, a bonding drum 2 and a feeding device 3. The production process for carcass tube for agricultural tires includes: the bladder side drum 6 expands to a large diameter state, and the outer peripheral surface of the bladder side drum 6 is flush with the outer peripheral surface of the bonding drum 2; the bladder side drum 6 and the bonding drum 2 rotate synchronously, and the feeding device 3 feeds the bonding drum 2 to complete the bonding of the inner liner, the cord one and the cord two in sequence; the bladder side drum 6 shrinks to a small diameter state, and the positive and negative packing device 5 approaches the bonding drum 2, and the positive and negative packing device 5 puts the rubber hoops hanging on both sides of the bonding drum 2 on the tire bead; the bladder side drum 6 expands, and the bladder 64 reverses the rubber on both sides of the bonding drum 2, and flattens the tire bead apex rubber together, and the feeding device 3 feeds the bonding drum 2 to complete the bonding of the cord three and the sidewall, and the carcass processing is completed.

[0038] Before the carcass is produced, each production equipment is installed and arranged. There are multiple positive and negative packing devices 5 and bladder side drums 6, which are symmetrically arranged on both sides of the axis direction of the bonding drum 2, and the axis of the positive and negative packing device 5, the bladder side drum 6 and the main shaft 1 of the bonding drum 2 coincide. Among them, a structure for driving can be installed on one side of the bonding drum 2 to drive the positive and negative packing device 5 and the bladder side drum 6 on this side to move. Materials (such as cord fabric 1, cord fabric 2, inner liner, etc.) are placed on the feeding device 3, and each device is fed when it is working.

[0039] The bladder side drum 6 can be retracted to a small diameter state so that the forward and reverse packing device 5 can pass through and complete the tire beading action; it can also be expanded to a large diameter state with the same diameter as the expansion state of the bonding drum 2, and the two rotate together when bonding the inner liner, the first cord, and the second cord. When the bladder side drum 6 is reversed, it is retracted to a small diameter state, and air is inflated into the bladder 64, and the bladder 64 expands and completes the reverse packing with the help of the forward and reverse packing device 5.

[0040] The production process of this embodiment is as follows: the positive and negative packing device 5 is located far away from the bonding drum 2, the bladder side drum 6 expands to a large diameter state and is close to the bonding drum 2. At this time, the bonding drum 2 rotates together with the bladder side drum 6 to complete the bonding of the inner liner, the cord one, and the cord two in sequence. After the bonding is completed, the bladder side drum 6 shrinks to a small diameter state, and the positive and negative packing device 5 moves toward the bonding drum 2, and the positive packing fingers are used to tighten the hanging rubber on both sides and put them on the tire bead. After the tire bead is put on, the positive and negative packing device 5 returns to the initial position, and the bladder 64 expands to reverse the rubber on both sides and flatten it together with the tire bead triangle rubber. After the reverse packing is completed, the tire cord three is bonded, and then the positive packing pressure roller 7 is extended to wrap the hanging part of the rubber on both sides under the tire bead. After the positive packing is completed, the positive packing pressure roller 7 is retracted to fit the tire side, and then the positive packing pressure roller 7 is extended to compact the tire side rubber. A section of the tire body tube is manufactured.

[0041] In the process method of this embodiment, since the tire body bonding, tire body reverse wrapping and tire body positive wrapping are performed on the same drum, and the inner liner and the cord are bonded in the "large diameter" state, the tire body tube is pulled without expansion.

[0042] Furthermore, the feeding device 3 includes a first feeding rack 31 and a second feeding rack 32, and the tire carcass tube production process also includes: before the bonding drum 2 bonds the inner liner, the capsule side drum 6, the bonding drum 2 and the forward and reverse packing device 5 move to a first station coordinated with the first feeding rack 31; after the expansion of the capsule 64 is completed and before the bonding drum 2 bonds the cord three, the capsule side drum 6, the bonding drum 2 and the forward and reverse packing device 5 move to a second station coordinated with the second feeding rack 32.

[0043] Since there are many types of materials to be supplied, and different materials need to be used in different processes, if all materials are stored on the same feeding rack, the feeding rack will be bloated and inconvenient to load materials. Therefore, the feeding device 3 is divided into two different feeding racks, a first feeding rack 31 for placing the inner lining layer, the first curtain cloth, and the second curtain cloth, and a second feeding rack 32 for placing the third curtain cloth.

[0044] In the initial stage, the laminating drum 2 and the positive and negative wrapping device 5 are moved to the position of the first feeding rack 31, and the positive and negative wrapping device 5 is located away from the laminating drum 2. The bladder side drum 6 expands to a large diameter state and is close to the laminating drum 2. At this time, the laminating drum 2 and the bladder side drum 6 rotate together to complete the laminating of the inner liner, the first cord, and the second cord in sequence. After the reverse wrapping is completed, the laminating drum 2 and the positive and negative wrapping device 5 are moved to the position of the second feeding rack 32, and the third cord is laminated. After that, the positive wrapping pressure roller 7 extends to wrap the rubber material hanging on both sides under the tire bead.

[0045] By placing the raw materials required for different processes on two feeding racks respectively, it is avoided that all materials are placed on one material rack, which causes the feeding rack to be bloated and the material loading to be inconvenient, and it is convenient to feed materials during the tire body processing.

[0046] Furthermore, there are multiple positive and negative packing devices 5 and capsule side drums 6, and positive and negative packing devices 5 and capsule side drums 6 are arranged on both sides of the axial direction of the bonding drum 2. The agricultural tire carcass tube production process also includes: when the capsule side drum 6, the bonding drum 2 and the positive and negative packing devices 5 move, the capsule side drum 6 and the positive and negative packing devices 5 located on one side of the bonding drum 2 keep their positions unchanged, and the capsule side drum 6 and the positive and negative packing devices 5 located on the other side of the bonding drum 2 move axially with the bonding drum 2.

[0047] The positive and negative packing device 5 located on one side of the laminating drum 2 is fixed and always located on one side of the first feeding rack 31, so as to facilitate the laminating of the inner lining layer, the curtain cloth 1 and the curtain cloth 2. The positive and negative packing device 5 on the other side can move together with the laminating drum 2, and after the negative packing is completed, it moves to the position of the second feeding rack 32 to cooperate with the curtain cloth 3. By fixing one set of the positive and negative packing device 5 and the capsule side drum 6, and the other set of the capsule side drum 6 and the positive and negative packing device 5 can be moved, it is convenient to load the corresponding raw materials at different steps of the process.

[0048] In this embodiment, the agricultural tire carcass tube production equipment also includes a positive pressure roller 7 arranged on the feeding device 3, and the agricultural tire carcass tube production process also includes: when laminating the cord three and the sidewall, after laminating the cord three, the positive pressure roller 7 is extended to wrap the rubber material hanging on both sides of the laminating drum 2 to the inner side of the tire bead, and then the positive pressure roller 7 is retracted, and the laminating drum 2 is laminated to the sidewall. After laminating the sidewall, the positive pressure roller 7 is extended to compact the sidewall.

[0049] After the positive packing is completed, the positive packing pressure roller 7 is retracted to fit the sidewall, and then the positive packing pressure roller 7 is extended to compact the rubber material of the sidewall. At this point, a section of the carcass tube is manufactured. After the positive packing is completed, the rubber material of the sidewall is compacted by the positive packing pressure roller 7 to increase the stability of the carcass after the positive packing.

[0050] Furthermore, the agricultural tire carcass tube production equipment also includes a tire unloading device, and the agricultural tire carcass tube production process also includes: after the carcass tube processing is completed, the tire unloading device unloads the carcass tube from the bonding drum 2 and transfers it to the subsequent process.

[0051] By unloading and transferring the tire body barrel through the tire unloading device, the automation degree of the entire process can be improved, and the occurrence of direct unloading by workers can be reduced, thereby reducing the work intensity of the workers.

[0052] In this embodiment, the capsule side drum 6 includes a side drum driving member 621, a slider 622 and a lifting block 623, and the first inclined surface of the slider 622 is abutted against the second inclined surface of the lifting block 623. The agricultural tire carcass tube production process also includes: when the capsule side drum 6 radially expands and contracts, the side drum driving member 621 drives the slider 622 to move axially, and the first inclined surface of the slider 622 is transmission-matched with the second inclined surface of the lifting block 623, and the second inclined surface moves along the first inclined surface and drives the lifting block 623 to move radially.

[0053] The capsule side drum 6 can be contracted to a small diameter state so that the forward and reverse packing device 5 can pass through and complete the tire beading action; it can also be expanded to a large diameter state with the same diameter as the expansion state of the bonding drum 2, and the two rotate together when bonding the inner liner, cord one, and cord two. The slider 622 is driven to move axially by the side drum driving member 621, which can drive the first inclined surface and the second inclined surface that cooperate with each other to move in coordination with each other. Through the conversion effect of the inclined surface, the axial movement of the slider 622 can be changed to the radial movement of the lifting block 623, thereby realizing the lifting and lowering of the lifting block 623 in the radial direction, thereby realizing the change of the diameter of the capsule side drum 6. When it is necessary to process tire bodies of different sizes, the diameter of the capsule side drum 6 is changed by the radial movement of the lifting block 623 to adapt to tire bodies of different sizes.

[0054] In this embodiment, the front and back wrapping device 5 includes a front wrapping finger assembly 53 and a buckle ring assembly 52, and the front wrapping finger assembly 53 is axially movable relative to the buckle ring assembly 52. ​​The agricultural tire carcass tube production process also includes: when the front and back wrapping device 5 tightens the rubber material hanging on both sides of the bonding drum 2 and puts the tire bead, the front wrapping finger assembly 53 moves axially relative to the buckle ring assembly 52 in the direction close to the bonding drum 2, and the front wrapping finger of the front wrapping finger assembly 53 is flipped and unfolded, and then the buckle ring assembly 52 moves relative to the front wrapping finger assembly 53 in the direction close to the bonding drum 2, the buckle ring assembly 52 puts the steel ring, and the buckle ring assembly 52 squeezes the outer side of the front wrapping finger and drives the front wrapping finger to flip and shrink, and the front wrapping finger tightens the hanging rubber material on both sides of the carcass tube.

[0055] The positive and negative packing device 5 mainly tightens the overhanging rubber material on the carcass tube both sides by just packing. In the just packing process, by the relative movement of the buckle ring assembly 52 and just packing the finger assembly 53, the just packing process of the carcass tube is realized.

[0056] Furthermore, the agricultural tire carcass tube production process also includes: when the bladder side drum 6 expands to a large diameter state, the forward and reverse packing device 5 is located at an initial position away from the bonding drum 2; after the forward and reverse packing device 5 completes the tightening of the rubber hanging on both sides of the bonding drum 2 and the tire bead, the forward and reverse packing device 5 is reset to the initial position.

[0057] In different steps of the process, different devices need to be in different positions to prevent interference between different devices and improve the working stability of each device.

[0058] In this embodiment, the capsule side drum 6 includes a side drum driving member 621, a slider 622 and a lifting block 623. The first inclined surface of the slider 622 is in abutment with the second inclined surface of the lifting block 623. The positive and negative packaging device 5 includes a positive packaging finger assembly 53, a buckle ring assembly 52 and a buckle ring radial driving member. The positive packaging finger assembly 53 and the buckle ring assembly 52 move radially synchronously. The buckle ring assembly 52 has a driving inclined surface. The output end of the buckle ring radial driving member is connected to the driving inclined surface. The production process of the agricultural tire carcass barrel also includes: before the rubber material is bonded, according to the to-be-processed The parameters of the large diameter state and the small diameter state of the bladder side drum 6 are adjusted according to the size of the carcass tube. The slider 622 is driven to move axially through the side drum driving member 621. The first inclined surface of the slider 622 is matched with the second inclined surface of the lifting block 623. The second inclined surface moves along the first inclined surface and drives the lifting block 623 to move radially. The diameters of the positive wrapping finger assembly 53 and the buckle ring assembly 52 are adjusted according to the size of the carcass tube to be processed. When the output end of the buckle radial driving member moves axially, the driving inclined surface drives the positive wrapping finger assembly 53 and the buckle ring assembly 52 to move radially as a whole.

[0059] When the size of the carcass tube to be processed changes, the bladder side drum 6 and the positive and negative packing device 5 can be adjusted to match the size of the carcass to be processed. The bladder side drum 6 drives the slider 622 to slide through the side drum driving member 621, and converts the axial movement of the slider 622 into the radial movement of the lifting block 623 through the mutual cooperation of the first inclined surface and the second inclined surface, thereby realizing the change of the diameter of the bladder side drum 6. The positive and negative packing device 5 changes the diameter of the circle surrounded by the buckle ring assembly 52 and the positive packing finger assembly 53 through the buckle ring radial driving member. Before processing the carcass tube, by adjusting the bladder side drum 6 and the positive packing finger assembly 53 to match the diameter of the carcass tube to be processed, carcass tubes of different sizes can be processed.

[0061] like Figures 1 to 4 The agricultural tire carcass tube production equipment shown in the figure includes a main shaft 1, a bonding drum 2, a feeding device 3, a driving device 4, a plurality of positive and negative packaging devices 5 and a plurality of capsule side drums 6, the bonding drum 2 is movably sleeved on the outside of the main shaft 1, the feeding device 3 is located at the circumferential side of the bonding drum 2, the driving device 4 includes a first driving assembly and a second driving assembly, the first driving assembly and the second driving assembly are respectively located at the two ends of the main shaft 1, the first driving assembly and / or the second driving assembly are movably connected along the axial direction of the main shaft 1, the positive and negative packaging devices 5 are movably provided on both axially opposite sides of the bonding drum 2, the positive and negative packaging devices 5 on both sides are respectively driven and connected to the first driving assembly and the second driving assembly, the bonding drum 2 is movably provided on both axially opposite sides, the capsule side drums 6 on both sides are respectively driven and connected to the first driving assembly and the second driving assembly, and the axes of the positive and negative packaging devices 5, the capsule side drums 6 and the bonding drum 2 coincide.

[0062] The positive and negative packing device 5 is located far away from the bonding drum 2, and the bladder side drum 6 expands to a large diameter state and is close to the bonding drum 2. At this time, the bonding drum 2 rotates together with the bladder side drum 6 to complete the bonding of the inner liner, the first cord, and the second cord in sequence. After the bonding is completed, the bladder side drum 6 shrinks to a small diameter state, and the positive and negative packing device 5 moves toward the bonding drum 2, and uses the positive packing finger to tighten the hanging rubber on both sides and put it on the tire bead. After the tire bead is put on, the positive and negative packing device 5 returns to the initial position, and the bladder 64 expands to reverse the rubber on both sides and flatten it together with the tire bead apex rubber. After the reverse packing is completed, the third cord is bonded, and then the positive packing pressure roller 7 extends to wrap the hanging part of the rubber on both sides under the tire bead.

[0063] In this process, the bonding drum 2 is mainly used for placing the carcass tube and performing the bonding process. The feeding device 3 is used for placing the inner liner, cord one, cord two and cord three for use in bonding. The positive and negative packing device 5 and the bladder side drum 6 process the carcass tube to complete the bonding and reverse packing of the carcass tube. Multiple positive and negative packing devices 5 and multiple bladder side drums 6 are respectively arranged on both sides of the axial direction of the bonding drum 2, which is convenient for processing the carcass tube. The first drive assembly and the second drive assembly are respectively connected to the positive and negative packing devices 5 and the bladder side drum 6 located on both sides of the carcass tube. By controlling the first drive assembly or the second drive assembly, it is convenient to drive the bladder side drum 6 or the positive and negative packing device 5 to move.

[0064] Furthermore, the feeding device 3 includes a first feeding rack 31 and a second feeding rack 32 for placing different adhesives. The first feeding rack 31 and the second feeding rack 32 are arranged along the axial direction of the laminating drum 2 and are located on the same side of the circumferential direction of the laminating drum 2 .

[0065] Since there are many types of materials to be supplied, and different materials need to be used in different processes, if all materials are stored on the same feeding rack, the feeding rack will be bloated and inconvenient to load materials. Therefore, the feeding device 3 is divided into two different feeding racks, a first feeding rack 31 for placing the inner lining layer, the first curtain cloth, and the second curtain cloth, and a second feeding rack 32 for placing the third curtain cloth.

[0066] In the initial stage, the laminating drum 2 and the positive and negative wrapping device 5 are moved to the position of the first feeding rack 31, and the positive and negative wrapping device 5 is located away from the laminating drum 2. The bladder side drum 6 expands to a large diameter state and is close to the laminating drum 2. At this time, the laminating drum 2 and the bladder side drum 6 rotate together to complete the laminating of the inner liner, the first cord, and the second cord in sequence. After the reverse wrapping is completed, the laminating drum 2 and the positive and negative wrapping device 5 are moved to the position of the second feeding rack 32, and the third cord is laminated. After that, the positive wrapping pressure roller 7 extends to wrap the rubber material hanging on both sides under the tire bead.

[0067] By placing the raw materials required for different processes on two feeding racks respectively, it is avoided that all materials are placed on one material rack, which causes the feeding rack to be bloated and the material loading to be inconvenient, and it is convenient to feed materials during the tire body processing.

[0068] Furthermore, the agricultural tire carcass tube production equipment also includes a positive pressure roller 7, and the positive pressure roller 7 is located on a side of the second feeding rack 32 close to the bonding drum 2.

[0069] After the positive packing is completed, the positive packing pressure roller 7 is retracted to fit the sidewall, and then the positive packing pressure roller 7 is extended to compact the rubber material of the sidewall. At this point, a section of the carcass tube is manufactured. After the positive packing is completed, the rubber material of the sidewall is compacted by the positive packing pressure roller 7 to increase the stability of the carcass after the positive packing.

[0070] like Figure 3 As shown, in this embodiment, the capsule side drum 6 includes an inner sleeve 61, a plurality of expansion and contraction components 62, a plurality of drum plates 63, a capsule 64 and an air nozzle 65. The inner sleeve 61 is mounted on the main shaft 1. Along the axial direction of the main shaft 1, the inner sleeve 61 is slidably connected to the main shaft 1. Along the circumferential direction of the inner sleeve 61, each expansion and contraction component 62 is installed at intervals on the outer circumferential surface of the inner sleeve 61. At least a portion of the expansion and contraction component 62 is expandable and contractible along the radial direction of the inner sleeve 61. The drum plate 63 is connected to the expansion and contraction component 62 and is located on the outer circumferential surface of the expansion and contraction component 62. The expansion and contraction component 62 drives the drum plate 63 to move along the radial direction of the inner sleeve 61. The capsule 64 is mounted on the outer circumferential surface of the drum plate 63. The air nozzle 65 is connected to the capsule 64, and the air nozzle 65 is arranged on the side of the capsule 64 close to the inner sleeve 61.

[0071] When the side drum needs to be reversed, it is necessary to inflate the capsule 64, and the inflated capsule 64 moves toward the tire to complete the reversed tire. During the inflation of the capsule 64, the capsule 64 is inflated through the air nozzle 65 connected to the capsule 64, so that the connection between the capsule 64 and the outside is only located on the air nozzle 65, and the air nozzle 65 is directly connected through the air pipe or other driving parts for inflation (such as an air pump), so that there is no other position on the capsule 64 for ventilation or exhaust, which can increase the sealing of the capsule 64 when it is expanded, and solve the sealing problem of the capsule 64 when it is expanded.

[0072] When the size of the tire that needs to be wrapped positively and negatively changes, the expansion and contraction component 62 will drive the drum plate 63 to move along the radial direction of the inner sleeve 61, changing the circle formed by the drum plate 63 around the inner sleeve 61. Since the capsule 64 is installed on the drum plate 63, when the diameter of the circle formed by the drum plate 63 changes, the diameter of the capsule 64 will also change accordingly, thereby adapting to rubbers of different sizes and being able to process tires of different sizes. There is no need to replace the capsule side drum 6, thereby solving the problem of time-consuming and labor-intensive replacement.

[0073] Furthermore, the expansion and contraction assembly 62 includes a side drum driving member 621, a slider 622 and a lifting block 623. The slider 622 is drivingly connected to the side drum driving member 621. Along the axial direction of the inner sleeve 61, the slider 622 is slidingly connected to the inner sleeve 61. The side of the slider 622 away from the axis of the inner sleeve 61 has a first inclined surface. The lifting block 623 is radially movably arranged on the side of the slider 622 away from the axis of the inner sleeve 61. The side of the lifting block 623 close to the slider 622 has a second inclined surface abutting against the first inclined surface. The drum plate 63 is installed on the side of the lifting block 623 away from the slider 622.

[0074] The slider 622 and the lifting block 623 cooperate with each other through the first inclined surface and the second inclined surface that abut against each other. When the slider 622 moves along the axial direction of the main shaft 1, due to the conversion effect of the inclined surface, the lifting block 623 moves along the radial direction of the main shaft 1 under the action of the inclined surface. The drum plate 63 is installed on the lifting block 623. When the lifting block 623 is displaced in the radial direction of the main shaft 1, the drum plate 63 will move toward or away from the radial direction of the main shaft 1, thereby realizing the expansion and contraction process of the drum plate 63. The slider 622 is driven to move by the push rod of the side drum driving member 621, so that the drum plate 63 and the capsule 64 installed on the drum plate 63 can be expanded and contracted, thereby adapting to tires of different sizes.

[0075] like Figure 4As shown, in this embodiment, the positive and negative packaging device 5 includes an annular fixed frame 51, a plurality of buckle ring assemblies 52, a plurality of positive packaging finger assemblies 53 and a positive and negative packaging driving assembly 54, each buckle ring assembly 52 is arranged at intervals along the circumferential direction of the fixed frame 51, the buckle ring assembly 52 is radially movable relative to the fixed frame 51, the buckle ring assembly 52 has a buckle end for buckling, each positive packaging finger assembly 53 is arranged at intervals along the circumferential direction of the fixed frame 51, the positive packaging finger assembly 53 is connected to the inner side of the buckle ring assembly 52, and can be driven by the buckle ring assembly 52 along the radial direction of the fixed frame 51. The positive finger assembly 53 can be axially moved relative to the buckle ring assembly 52, and the positive finger assembly 53 includes a finger-shaped piece, which has a contracted state in which the finger-shaped piece is radially retracted due to the limit of the buckle end, and an expanded state in which the finger-shaped piece radially expands and rotates to avoid the buckle end. When the positive finger assembly 53 moves axially relative to the buckle ring assembly 52, the finger-shaped piece switches between the expanded state and the contracted state. The positive and negative enveloping driving assembly 54 is drivingly connected to the buckle ring assembly 52 and the positive finger assembly 53, and drives the buckle ring assembly 52 to move radially, the buckle ring assembly 52 to move axially, and the positive finger assembly 53 to move axially.

[0076] The positive finger assembly 53 is pushed out and opened, and then the buckle ring assembly 52 moves toward the drum to gather and shrink the positive finger, and finally buckle the tire bead on the side of the drum. There is a certain correlation between the stop diameter of the buckle ring assembly 52 and the diameter of the circular ring formed by the positive finger assembly 53, so when the tire formula changes the tire bead diameter, the stop diameter of the buckle ring assembly 52 and the diameter of the positive finger assembly 53 need to expand or shrink to the position of the formula parameter. In order to realize automatic specification change, the positive finger assembly 53 and the buckle ring assembly 52 are made into a structure that can expand or shrink together, and driven by the positive and negative packing driving assembly 54, the positive finger assembly 53 and the buckle ring assembly 52 can shrink or expand together to adapt to tires of different sizes. Afterwards, the power component drives the positive finger assembly 53 and the buckle ring assembly 52 to move axially to pack the tire positively and negatively.

[0077] When the size of the tire to be reversed changes, the stop diameter of the buckle ring assembly 52 and the diameter of the ring formed by the reversed finger assembly 53 need to be adjusted to match the tire with the changed size. At this time, the reversed driving assembly 54 needs to work to drive the buckle ring assembly 52 to move along the radial direction of the fixing frame 51, and change the stop diameter of the buckle ring assembly 52 to match the specifications of the tire to be reversed. Since the reversed finger assembly 53 is connected to the inner side of the buckle ring assembly 52, when the stop diameter of the buckle ring assembly 52 changes, the reversed finger assembly 53 will change with it to match the specifications of the tire barrel to be reversed.

[0078] By driving the radial movement of the buckle ring assembly 52 and the positive wrapping finger assembly 53 through the positive and negative wrapping driving assembly 54, the stop diameter of the buckle ring assembly 52 and the diameter of the circular ring formed by the positive wrapping finger assembly 53 can be changed, so as to adapt to tires of different sizes. There is no need to stop the machine to replace the positive wrapping finger assembly 53 and the buckle ring assembly, etc., which reduces the workload and the time spent on replacing parts, improves the overall production efficiency, and solves the problem of delaying production time due to frequent replacement of tooling in the prior art.

[0079] Since the range of variation of the stop diameter of the buckle ring assembly 52 and the diameter of the circular ring formed by the positive and negative wrapping finger assembly 53 is related to the radial movement of the buckle ring assembly 52, and the radial movement of the buckle ring is a continuous movement, it can stop at any position within its movement range under the drive of the positive and negative wrapping driving assembly 54. Therefore, this embodiment can be adapted to tires of various sizes, not limited to one or two, and has a wide range of applications.

[0080] Furthermore, the buckle ring assembly 52 includes a frame body 521, which is movably connected to the fixed frame 51 and the positive and negative wrapping finger assembly 53. The frame body 521 has a driving bevel, which forms an angle with the axial direction of the fixed frame 51. The positive and negative wrapping driving assembly 54 includes a buckle radial driving member, and the output end of the buckle radial driving member is drivingly connected to the driving bevel, and a guide rail structure is provided between the output end and the driving bevel. The output end is movably arranged along the axial direction of the fixed frame 51, and drives the frame body 521 to move radially through the driving bevel when moving.

[0081] The frame body 521 is driven to move along the axial direction of the fixed ring through the forward and reverse packaging driving component 54. Since the frame body 521 has a driving inclined surface, and the driving inclined surface forms an angle with the axial direction of the fixed frame 51, the movement of part of the frame body 521 along the axial direction of the fixed frame 51 is converted into movement in the radial direction of the fixed frame 51 through the rotation of the inclined surface, thereby realizing the movement of the fixed frame 51 along the radial direction of the fixed frame 51.

[0082] After the positive and negative package driving assembly 54 is working, it will drive the output end of the positive and negative package driving assembly 54 and the frame 521 to displace. Since the frame 521 has a driving inclined surface, and the output end of the positive and negative package driving assembly 54 cooperates with the driving inclined surface, when the frame 521 moves, the output end of the positive and negative package driving assembly 54 will be relatively displaced with the driving inclined surface. By arranging a guide rail between the output end of the driving member and the driving inclined surface, the relative displacement between the output end of the driving member and the driving inclined surface can be limited, preventing the two from being misaligned in the circumferential direction of the fixed frame 51, and increasing the stability of the relative displacement between the two.

[0083] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0084] 1. The layout of this application adopts a large-diameter laminating process, that is, the laminating diameter of the cord is the same as the diameter of the actual final tire body tube, and the cord has no circumferential stretching during the tire making process, and the tire cord density is high and the strength is good. Corresponding to this is a small-diameter laminating process, which is more common in the one-step process. The advantage of the small-diameter laminating process is that the current technology has a high degree of automation, but its cord has circumferential stretching, which affects the tire cord density and is lower than the tire tube strength manufactured by the large-diameter laminating process.

[0085] 2. When the size of the tire that needs to be wrapped positively and negatively changes, the expansion and contraction component 62 will drive the drum plate 63 to move along the radial direction of the inner sleeve 61, changing the circle formed by the drum plate 63 around the inner sleeve 61. Since the capsule 64 is installed on the drum plate 63, when the diameter of the circle formed by the drum plate 63 changes, the diameter of the capsule 64 will also change accordingly, thereby adapting to rubbers of different sizes and being able to process tires of different sizes. There is no need to replace the capsule side drum 6, thereby solving the problem of time-consuming and labor-intensive replacement.

[0086] 3. Since the range of variation of the stop diameter of the buckle ring assembly 52 and the diameter of the circular ring formed by the positive and negative wrapping finger assembly 53 is related to the radial movement of the buckle ring assembly 52, and the radial movement of the buckle ring is a continuous movement, it can stop at any position within its movement range under the drive of the positive and negative wrapping driving assembly 54. Therefore, the present application can be adapted to tires of various sizes, not limited to one or two, and has a wide range of applications.
