Description

Technical Field

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

[0002] Based on tire specifications, engineering tire forming machines can be divided into small-size structures (24-inch, 25-inch) and large-size structures (29-inch, 33-inch and above). According to the machine structure, they are further divided into single-stage two-drum forming machines and two-stage four-drum forming machines. Currently, the four-drum forming machine structure is the most common, all employing two-stage forming technology. In this structure, the tread winding station and the tire shaping station are on the same rotating platform, with the tire shaping and rolling processes alternating.

[0003] The existing technology has at least the following problems: First, it uses a lot of tire carcass transfer rings to transfer the tire carcass cylinder, and the large number of cylinders and testing components on the tire carcass transfer rings determines that it has a high failure rate; Second, the tire shaping and belt layer bonding are fast and quick, but the tread of large-size tires and giant tires needs to be wound in multiple layers, and the overall weight of the tread composite is large, the operation speed is slow and the time is long. The tire shell after tire shaping and belt layer bonding 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 five-drum forming machine. This invention reduces the use of tire carcass transfer rings and can process multiple tire shells simultaneously, effectively improving the production efficiency of tire forming machines.

[0005] The technical solution of this utility model to solve the technical problem is as follows: a five-drum forming machine, including a longitudinal track, a number of tire unloading transfer rings are provided on the longitudinal track, a shaping station is provided at one end of the longitudinal track, a tire body shaping device and a belt layer bonding device are provided on both sides of the shaping station, and at least two sets of tire tread winding drums are provided at the other end of the longitudinal track.

[0006] As an optimization, the tire carcass shaping device includes a tire carcass feeding rack, a rotating platform, and tire carcass bonding drums. The rotating platform is positioned between the shaping station and the tire carcass feeding rack. The rotating platform has two sets of parallel first transverse tracks, each with a tire carcass bonding drum, which are symmetrically arranged at their centers. The tire carcass feeding rack supplies the rubber components of the tire carcass to the bonding drums. The rotating platform allows the two sets of bonding drums to operate alternately: one set receives material from the feeding rack to form the tire carcass cylinder, while the other set shapes the tire carcass cylinder at the shaping station, improving production efficiency. The tire carcass bonding drums serve two purposes: first, they form the tire carcass cylinder at the feeding rack; second, they work with the shaping rollers at the shaping station to form the tire shell.

[0007] As an optimization, the belt layer bonding device includes a belt layer feeding rack, a belt layer bonding drum, and a belt layer transfer ring. The belt layer bonding drum is located on one side of the belt layer feeding rack, and the belt layer transfer ring is positioned between the shaping station and the belt layer bonding drum via a second transverse track. By providing the belt layer feeding rack, belt layer adhesive components can be supplied to the belt layer bonding drum; by providing the belt layer bonding drum, multiple belt layers can be bonded to form a belt layer composite; by providing the belt layer transfer ring, the belt layer composite can be transferred from the belt layer bonding drum to the tire carcass bonding drum located at the shaping station, and fitted onto the center of the outer side of the tire carcass cylinder on the tire carcass bonding drum; by providing the second transverse track, the belt layer transfer ring can be easily moved between the shaping station and the belt layer bonding drum.

[0008] As an optimization, two sets of tread winding drums are provided, with each set positioned on either side of the longitudinal track via a third lateral track. The third lateral track allows the tread winding drums to move laterally, receiving the tire shell or delivering the tire blank. The two sets of tread winding drums can be flexibly arranged according to site conditions, offering strong adaptability.

[0009] As an optimization, two sets of tread winding drums are provided. The two sets of tread winding drums are respectively set on one side of the longitudinal track via a third lateral track, and the two sets of tread winding drums are parallel to each other. By setting the third lateral track, the tread winding drums can be moved laterally to receive the tire shell or deliver the tire blank. The two sets of tread winding drums can be flexibly arranged according to the site conditions, and have strong adaptability.

[0010] As an optimization, a tire removal area is provided at the other end of the longitudinal track. By setting up the tire removal area, a tire blank with the tread already wrapped can be received and stored.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] By setting up longitudinal tracks and tire unloading transfer rings, the tire shell processed at the shaping station can be transferred to the tread winding drum, and the tire blank with the tread wound can be transferred to the tire unloading area. By setting up the shaping station, the tire carcass and belt layer composite can be rolled and shaped to form the tire shell, reducing the use of the tire carcass transfer ring. By setting up the tire carcass shaping device, the tire carcass can be formed. By setting up the belt layer bonding device, it is convenient for workers to bond and form the belt layer composite. By setting up the tread winding drum, the tread can be wound onto the tire shell to form the tire blank. This completely separates the tire carcass and rubber component bonding process, the tire shaping and rolling process, and the tread winding process, allowing them to be carried out independently, greatly improving production efficiency.

[0015] 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.

[0016] Example 1

[0017] Figure 1 As shown in the figure, in one embodiment of this utility model, a five-drum forming machine includes a longitudinal track 1, on which several sets of tire unloading transfer rings 2 are provided. One end of the longitudinal track 1 is provided with a shaping station 3. On both sides of the shaping station 3, a tire body shaping device and a belt layer bonding device are respectively provided. At least two sets of tire tread winding drums 4 are provided at the other end of the longitudinal track 1. One side of the tire tread winding drum 4 is provided with a tire tread feeding frame 5, and the other side of the tire tread winding drum 4 is provided with a pressure roller 16.

[0018] By setting up the longitudinal track 1 and the tire unloading transfer ring 2, the tire shell processed at the shaping station 3 can be transferred to the tread winding drum 4, and the tire blank with the tread wound can be transferred to the tire unloading area. By setting up the shaping station 3, the tire body cylinder and belt layer composite can be rolled and shaped to form the tire shell, reducing the use of the tire body transfer ring. By setting up the tire body shaping device, the tire body cylinder can be formed. By setting up the belt layer bonding device, it is convenient for workers to bond and form the belt layer composite. By setting up the tread winding drum 4, the tread supplied by the tread feeding rack 5 can be wound onto the tire shell and cooperate with the pressure roller 16 to form the tire blank. This completely separates the bonding process of the tire body and rubber parts, the tire shaping and rolling process, and the tread winding process, allowing them to be carried out independently, greatly improving production efficiency.

[0019] The tire carcass shaping device includes a tire carcass feeding frame 6, a rotating platform 7, and a tire carcass bonding drum 8. The rotating platform 7 is located between the shaping station 3 and the tire carcass feeding frame 6. The rotating platform 7 has two sets of parallel first transverse tracks 9, and each set of first transverse tracks 9 has a tire carcass bonding drum 8, which are symmetrically arranged. By setting the tire carcass feeding frame 6, the rubber components of the tire carcass can be supplied to the tire carcass bonding drum 8. By setting the rotating platform 7, the two sets of tire carcass bonding drums 8 can work alternately. One set receives the material from the tire carcass feeding frame 6 to form the tire carcass cylinder, while the other set shapes the tire carcass cylinder at the shaping station 3, thereby improving production efficiency. By setting the tire carcass bonding drum 8, the tire carcass cylinder can be formed at the tire carcass feeding frame 6, and the tire shell can be formed at the shaping station 3 in conjunction with the shaping pressure roller.

[0020] The belt layer bonding device includes a belt layer feeding rack 10, a belt layer bonding drum 11, and a belt layer transfer ring 12. The belt layer bonding drum 11 is located on one side of the belt layer feeding rack 10, and the belt layer transfer ring 12 is located between the shaping station 3 and the belt layer bonding drum 11 via a second transverse track 13. By setting up the belt layer feeding rack 10, belt layer adhesive components can be provided to the belt layer bonding drum 11; by setting up the belt layer bonding drum 11, multiple belt layers can be bonded to form a belt layer composite; by setting up the belt layer transfer ring 12, the belt layer composite can be transferred from the belt layer bonding drum 11 to the tire carcass bonding drum 8 located at the shaping station 3, and fitted onto the center of the outer side of the tire carcass tube on the tire carcass bonding drum 8; by setting up the second transverse track 13, the belt layer transfer ring 12 can be easily moved between the shaping station 3 and the belt layer bonding drum 11.

[0021] Two sets of tread winding drums 4 are provided, and the two sets of tread winding drums 4 are respectively set on both sides of the longitudinal track 1 via the third transverse track 14. By setting the third transverse track 14, the tread winding drums 4 can be moved laterally to receive the tire shell or send out the tire blank. The two sets of tread winding drums 4 can be flexibly arranged according to the site conditions, and have strong adaptability.

[0022] The other end of the longitudinal track 1 is provided with a tire removal area 15. By providing the tire removal area 15, a tire blank with the tread wrapped around it can be received and stored.

[0023] Example 2

[0024] The difference between this embodiment and the first embodiment is that the tread winding drum 4 is provided in two sets. The two sets of tread winding drums 4 are respectively set on one side of the longitudinal track 1 via the third transverse track 14, and the two sets of tread winding drums 4 are parallel to each other. By setting the third transverse track 14, the tread winding drum 4 can be moved laterally to receive the tire shell or send out the tire blank. The two sets of tread winding drums 4 can be flexibly arranged according to the site conditions, and have strong adaptability.

[0025] During production, the tire body feeding rack 6 first supplies materials to a set of tire body bonding drums 8 on the rotating platform 7, which are close to the tire body feeding rack 6. The workers then bond the inner liner, tire body, and other adhesive components onto the tire body bonding drums 6 to form a tire body cylinder. Next, the two sets of tire body bonding drums 8 begin to move towards each other on the first transverse track 9, shrinking to the minimum rotation diameter to reduce the floor space. Then, the rotating platform 7 rotates 180° to change the position of the two sets of tire body bonding drums 8. The two sets of tire body bonding drums 8 begin to move away from each other and extend outward. The other set of tire body bonding drums 8 approaches the tire body feeding rack 6 to bond the next set of tire body cylinders, while the tire body bonding drum 8 with the tire body cylinder enters the shaping station 3.

[0026] While the tire carcass is being bonded, the belt layer feeding rack 10 supplies material to the belt layer bonding drum 11. The worker applies multiple layers of belt layers onto the belt layer bonding drum 11 to form a composite. The belt layer transfer ring 12 moves on the second transverse track 13 and fits onto the outside of the belt layer bonding drum 11. The belt layer transfer ring 12 retracts to clamp the belt layer composite. Then the belt layer bonding drum 11 retracts to detach from the belt layer composite. The belt layer transfer ring 12 then moves with the belt layer composite on the second transverse track 13 toward the shaping station 3 and fits onto the tire carcass bonding drum 8 with the tire carcass. Then the belt layer transfer ring 12 expands outward to loosen the belt layer composite, which falls into the center of the tire carcass. The belt layer composite and the tire carcass are shaped and rolled at the shaping station 3 to form the tire shell. Then the tire carcass moves toward another set of tire carcass bonding drums 8 to leave space for the tire removal transfer ring 2.

[0027] The tire unloading transfer ring 2 moves to the shaping station 3 on the longitudinal track 1. The tire carcass bonding drum 8, carrying the tire shell, is inserted into the tire unloading transfer ring 2. The tire unloading transfer ring 2 retracts to clamp the tire shell, and the tire carcass bonding drum 8 retracts to detach from the tire shell. Then, the two sets of tire carcass bonding drums 8 begin to move towards each other on the first transverse track 9, preparing for the rotation of the rotating platform 7 and the alternation of the two sets of tire carcass bonding drums 8. Meanwhile, the tire unloading transfer ring 2, carrying the tire shell, moves towards the tread winding drum 4 on the longitudinal track 1. When it reaches one side of a set of tread winding drums 4, the tread winding drum 4 moves towards the tire unloading station on the third transverse track 14. The transfer ring 2 moves and inserts into the tire shell. Then, the tread winding drum 4 expands outward to support the tire shell. The tire unloading transfer ring 2 expands outward to detach from the tire shell, and the tread winding drum 4 returns to its original position with the tire shell. The workers use the tread feeding rack 5 and the tread winding device to wind the tread composite onto the tire shell. The tire tread is then rolled by the pressure roller 16 to form the 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 unloading transfer ring 2 to another set of tread winding drums 4 for winding, so as to achieve smooth operation of the production line and greatly improve production efficiency.

[0028] After the tire blank is formed, the tire removal transfer ring 2 moves along the longitudinal track 1 to one side of the tread winding drum 4 where the tire blank is located. The tread winding drum 4, carrying the tire blank, inserts into the tire removal transfer ring 2. The tire removal transfer ring 2 retracts to clamp the tire blank, and the tread winding drum 4 retracts to detach from the tire blank and return to its original position. The tire removal transfer ring 2, carrying the tire blank, moves along the longitudinal track 1 to the tire removal area 15 for tire removal, completing the production process. This utility model can reduce the use of tire body transfer rings and can process multiple sets of tire shells simultaneously, effectively improving the production efficiency of the tire forming machine.
