Description

Technical Field

[0001] This utility model relates to the technical field of tire production equipment, and in particular to a giant tire forming machine. Background Technology

[0002] Currently, the structure of giant tire forming machines is the traditional two-end, four-drum structure, and there is also a one-time, two-drum structure. However, the production process is unstable, the bladder reverse wrapping is difficult, and the quality of the formed tire blank is inconsistent. In the traditional process, the inner liner, tire body, and other rubber components need to be bonded to the tire body drum. Then, the tire body drum moves to the tire body transfer ring, and is transferred to a first-stage shaping drum. The first-stage shaping drum, together with a tailstock, completes the bonding of the tire bead and gasket rubber and tire shaping. Then, it is transferred again to the second-stage shaping drum through the tire body transfer ring, where the belt layer bonding, tire shaping, and tread winding are performed.

[0003] The existing technology has at least the following problems: First, a tail section moves back and forth on a separate track, which takes up a large area and is not conducive to equipment layout; Second, the belt layer bonding and tire shaping are fast and quick, but the tread of giant tires needs to be wound in multiple layers, and the overall weight of the tread composite is large, resulting in slow operation speed and long time consumption. After the belt layer bonding and tire shaping, the tire shell needs to wait for the tread winding operation of the previous set of tire shells to be completed before the tread winding can be carried out, resulting in a long overall time consumption and low production efficiency. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by developing a giant tire forming machine. This invention can reduce the lateral footprint of the equipment and process multiple tire shells simultaneously, effectively improving the production efficiency of giant tires.

[0005] The technical solution of this utility model to solve the technical problem is as follows: a giant tire forming machine includes a longitudinal track, a tire body shaping device is provided at one end of the longitudinal track, and a number of tire tread winding drums are provided at the other end of the longitudinal track. A tire tread winding device is provided on one side of the tire tread winding drum. The tire body shaping device includes a tailstock section and at least one set of tire body transfer rings. The tire body transfer rings and the tailstock section are both arranged on the longitudinal track.

[0006] As an optimization, the tire carcass shaping device also includes a first-stage shaping device and a second-stage shaping device, which are arranged along one end of the longitudinal track to the other. The first-stage shaping device serves three purposes: first, it forms the tire carcass tube; second, it attaches the corresponding first rubber component to the tire carcass tube; and third, it performs shaping and rolling after wrapping to form the second rubber component. The second-stage shaping device receives the second rubber component after the first-stage shaping and attaches the belt layer to it. After the second-stage shaping and rolling, the tire shell is formed.

[0007] As an optimization, the shaping device includes a tire carcass bonding drum, a first-stage shaping drum, and a tire carcass feeding frame. The tire carcass bonding drum and the first-stage shaping drum are respectively set on both sides of the longitudinal track via a first transverse track, and the tire carcass feeding frame is set on one side of the tire carcass bonding drum. By setting the tire carcass bonding drum and the tire carcass feeding frame, the inner liner, tire carcass, and other rubber components can be bonded to the tire carcass bonding drum to form a tire carcass cylinder. The tire carcass cylinder can be transferred to the first-stage shaping drum through a tire carcass transfer ring. By setting the first-stage shaping drum, a first-stage tailstock can be used to bond the tire bead and gasket rubber to the tire carcass cylinder, and reverse wrapping and rolling are performed by reverse wrapping pressure rollers.

[0008] As an optimization, the two-stage shaping device includes a belt layer feeding frame, a belt layer bonding drum, a belt layer transfer ring, and a two-stage shaping drum. The belt layer bonding drum and the two-stage shaping drum are respectively set on both sides of the longitudinal track via a second transverse track, and the belt layer transfer ring is set on the longitudinal track. By setting the belt layer feeding frame and the belt layer bonding drum, multiple belt layers can be bonded on the belt layer bonding drum to form a belt layer composite. By setting the belt layer transfer ring, the belt layer composite can be transferred to the two-stage shaping drum. By setting the two-stage shaping drum, it can receive the second adhesive component after the first shaping stage, and it can receive the belt layer composite. The belt layer composite can be wrapped around the outer center of the second adhesive component and rolled by two-stage pressure rollers to form a tire shell. The tire shell can be transferred to the tire tread winding drum through the tire body transfer ring to form a tire carcass.

[0009] As an optimization, several sets of tread winding drums are respectively set on one side of the longitudinal track via a third transverse track. This allows for flexible arrangement based on the site conditions, providing strong site adaptability.

[0010] As an optimization, several sets of tread winding drums are respectively set on both sides of the longitudinal track via a third transverse track. This allows for flexible arrangement based on the site conditions, providing strong site adaptability.

[0011] As an optimization, a tire transfer ring is also provided on the longitudinal track, and a tire removal area is provided at the other end of the longitudinal track. By setting up the tire transfer ring, the tire blank can be transferred to the tire removal area for unloading and flat placement.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By setting a longitudinal track, the tire carcass transfer ring and the first-stage tailstock can move longitudinally. The tire carcass transfer ring and the first-stage tailstock share a track, which can reduce the lateral footprint of the equipment and facilitate equipment layout. By setting several sets of tread winding drums and tread winding devices, the tire bonding belt layer shaping and rolling and tread rubber winding are separated, so that multiple sets of tire shells can be tread wound at the same time, which greatly improves production efficiency. By setting a tire carcass transfer ring, the tire carcass cylinder or rubber component can be transferred in the tire carcass shaping device. By setting a first-stage tailstock, the tire carcass cylinder can be assisted in the first-stage forming. Attached Figure Description

[0016] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0017] Example 1

[0018] Figure 1 As one embodiment of this utility model, such as Figure 1 As shown, a giant tire forming machine includes a longitudinal track 1, a tire body shaping device at one end of the longitudinal track 1, and several sets of tire tread winding drums 2 at the other end of the longitudinal track 1. A tire tread winding device 3 is provided on one side of the tire tread winding drum 2. The tire body shaping device includes a tailstock 4 and several sets of tire body transfer rings 5. The tire body transfer rings 5 ​​and the tailstock 4 are both arranged on the longitudinal track 1.

[0019] By setting the longitudinal track 1, the tire carcass transfer ring 5 and the first-stage tailstock 4 can move longitudinally. The tire carcass transfer ring 5 and the first-stage tailstock 4 share a track, which can reduce the lateral footprint of the equipment and facilitate equipment layout. By setting several sets of tread winding drums 2 and tread winding devices 3, the tire bonding belt layer shaping and rolling and tread rubber winding are separated, so that multiple sets of tire shells can be tread wound at the same time, which greatly improves production efficiency. By setting the tire carcass transfer ring 5, the tire carcass cylinder or rubber component can be transferred in the tire carcass shaping device. By setting the first-stage tailstock 4, the tire carcass cylinder can be assisted in the first-stage forming.

[0020] The tire shaping device also includes a first-stage shaping device and a second-stage shaping device, which are arranged along one end of the longitudinal track 1 to the other. The first-stage shaping device serves three purposes: first, it forms the tire carcass; second, it attaches the corresponding first rubber component to the tire carcass; and third, it performs shaping and rolling after wrapping to form the second rubber component. The second-stage shaping device receives the second rubber component after the first-stage shaping and attaches the belt layer to it. After the second-stage shaping and rolling, the tire shell is formed.

[0021] A shaping device includes a tire body bonding drum 6, a first-stage shaping drum 7, and a tire body feeding rack 8. The tire body bonding drum 6 and the first-stage shaping drum 7 are respectively set on both sides of the longitudinal track 1 via a first transverse track 9, and the tire body feeding rack 8 is set on one side of the tire body bonding drum 6. By setting the tire body bonding drum 6 and the tire body feeding rack 8, the inner liner, tire body, and other rubber components can be bonded on the tire body bonding drum 6 to form a tire body cylinder. The tire body cylinder can be transferred to the first-stage shaping drum 7 via the tire body transfer ring 5. By setting the first-stage shaping drum 7, the tire bead and gasket rubber can be bonded on the tire body cylinder in conjunction with the first-stage tailstock 4, and the tire body cylinder can be rolled back by the back-wrapping pressure roller.

[0022] The two-stage shaping device includes a belt layer feeding rack 10, a belt layer bonding drum 11, a belt layer transfer ring 12, and a two-stage shaping drum 13. The belt layer bonding drum 11 and the two-stage shaping drum 13 are respectively set on both sides of the longitudinal track 1 via a second transverse track 14, and the belt layer transfer ring 12 is set on the longitudinal track 1. By setting the belt layer feeding rack 10 and the belt layer bonding drum 11, multiple belt layers can be bonded on the belt layer bonding drum 11 to form a belt layer composite. By setting the belt layer transfer ring 12, the belt layer composite can be transferred to the two-stage shaping drum 13. By setting the two-stage shaping drum 13, the second adhesive component after the first shaping stage can be received, and the belt layer composite can be received. The belt layer composite can be wrapped around the center of the outer side of the second adhesive component and rolled by two-stage pressure rollers to form a tire shell. The tire shell can be transferred to the tread winding drum 2 via the tire body transfer ring 5 to form a tire carcass.

[0023] Several sets of tire tread winding drums 2 are respectively set on one side of the longitudinal track 1 via the third transverse track 15. They can be arranged according to the site, and have strong site adaptability.

[0024] The longitudinal track 1 is also equipped with a tire removal transfer ring 16, and the other end of the longitudinal track 1 is equipped with a tire removal area 17. By setting up the tire removal transfer ring 16, the tire blank can be transferred to the tire removal area 17 for tire removal and flat placement.

[0025] Example 2

[0026] The difference between this embodiment and Embodiment 1 is that several sets of tread winding drums 2 are respectively set on both sides of the longitudinal track 1 via the third transverse track 15. This allows for flexible arrangement according to the site conditions, providing strong site adaptability.

[0027] During production, the tire carcass feeding rack 8 first supplies material to the tire carcass bonding drum 6. Workers then bond the inner liner, tire carcass, and other adhesive components onto the tire carcass bonding drum 6 to form the tire carcass tube. Next, the tire carcass transfer ring 5 moves along the longitudinal track 1 between the tire carcass bonding drum 6 and a shaping drum 7. The tire carcass bonding drum 6 moves closer to the tire carcass transfer ring 5 along the first transverse track 9, and the drum body of the tire carcass bonding drum 6 inserts into the tire carcass transfer ring 5. At this point, the tire carcass transfer ring 5 retracts to clamp the tire carcass tube. Then, the tire carcass bonding drum 6 retracts to detach from the tire carcass tube and returns to its original position on the first transverse track 9 to begin bonding the next set of tire carcass tubes. Meanwhile, the shaping drum 7 moves along the first transverse track 9... The tire carcass transfer ring 5 on track 9 approaches and inserts into the tire carcass tube, then begins to expand outward until it contacts and supports the tire carcass tube. At this time, the tire carcass transfer ring 5 expands outward to release the tire carcass tube, and a shaping drum 7 carries the tire carcass tube back to its original position on the first transverse track 9. The worker attaches the corresponding first rubber component to the tire carcass tube. A tailstock 4 moves on the longitudinal track 1 between the tire carcass bonding drum 6 and the shaping drum 7, and docks with the shaping drum 7. A reverse wrapping pressure roller is provided on one side of the shaping drum 7. The reverse wrapping pressure roller, the shaping drum 7, and the tire carcass bonding drum 6 cooperate with each other to complete the bonding of the tire bead and the pad rubber. The shaping is completed.

[0028] After the first shaping stage is completed, the tailstock 4 moves away on the longitudinal track 1. The tire carcass transfer ring 5 between the first and second shaping devices moves between the tire carcass bonding drum 6 and the first shaping drum 7. The first shaping drum 7, carrying the shaped tire carcass, inserts into the tire carcass transfer ring 5. The tire carcass transfer ring 5 retracts to clamp the tire carcass. The first shaping drum 7 retracts to detach from the tire carcass and returns to its original position on the first transverse track 9. The tire carcass transfer ring 5, carrying the tire carcass, moves on the longitudinal track 1 between the belt layer bonding drum 11 and the second shaping drum 13. The second shaping drum 13 moves towards the tire carcass transfer ring 5 on the second transverse track 14 and inserts into the tire carcass. The second shaping drum 13 expands outward to support the tire carcass. The tire carcass transfer ring 5 expands outward to release the tire carcass. The second shaping drum 13, carrying the tire carcass, returns to its original position on the second transverse track 14. The tire carcass transfer ring 5 moves away, and the belt layer transfer ring 12 moves to the belt layer bonding drum 11 and the second shaping drum 13. Between the shaping drums 13; while the belt layer feeding rack 10 supplies material to the belt layer bonding drum 11, the operator applies multiple layers of belt layer to the belt layer bonding drum 11 to form a composite. The belt layer bonding drum 11, carrying the composite, moves along the second transverse track 14 toward the belt layer transfer ring 12 and inserts into the belt layer transfer ring 12. The belt layer transfer ring 12 retracts to clamp the belt layer composite. The belt layer bonding drum 11 retracts to detach from the belt layer composite and returns to its original position. Then, the second shaping drum 13, carrying the tire body, moves along the second transverse track 14 toward the belt layer transfer ring 12 and inserts into the belt layer composite. At this time, the belt layer transfer ring 12 expands outward to loosen the belt layer composite. The belt layer composite falls in the center of the tire body. The second shaping drum 13, carrying the tire body and the belt layer composite, returns to its original position. The operator rolls the tire body and the belt layer composite with the second pressure roller to form the tire shell. The second shaping is completed.

[0029] After the second-stage shaping is completed, a set of tire carcass transfer rings 5 ​​moves between the belt layer bonding drum 11 and the second-stage shaping drum 13. The second-stage shaping drum 13, carrying the tire shell, inserts into the tire carcass transfer ring 5. The tire carcass transfer ring 5 retracts to clamp the tire shell. The second-stage shaping drum 13 retracts to detach from the tire shell and returns to its original position. The tire carcass transfer ring 5, carrying the tire shell, moves to one side of a set of tread winding drums 2 on the longitudinal track 1. The tread winding drum 2 moves towards the tire carcass transfer ring 5 on the third transverse track 15 and inserts into the tire shell. Then, the tread winding drum 2 expands outward to support the tire shell. The tire carcass transfer ring 5 expands outward to detach from the tire shell. The tread winding drum 2, carrying the tire shell, returns to its original position. The worker uses the tread winding device 3 to wind the tread composite onto the tire shell to form a tire blank. It should be noted that because the tread winding time is relatively long and the tire shell forming speed is relatively fast, a new set of tire shells can be transferred by the tire carcass transfer ring 5 to another set of tread winding drums 2 for winding, realizing smooth operation of the production line and greatly improving production efficiency.

[0030] After the tire blank is formed, the tire unloading transfer ring 16 moves along the longitudinal track 1 to one side of the tread winding drum 2 where the tire blank is located. The tread winding drum 2, carrying the tire blank, inserts into the tire unloading transfer ring 16. The tire unloading transfer ring 16 retracts to clamp the tire blank, and the tread winding drum 2 retracts to detach from the tire blank and return to its original position. The tire unloading transfer ring 16, carrying the tire blank, moves along the longitudinal track 1 to the tire unloading area 17 for tire unloading, completing the production process. This utility model can reduce the lateral footprint of the equipment and process multiple sets of tire shells simultaneously, effectively improving the production efficiency of giant tires.
