Description

Technical Field

[0001] This utility model relates to the technical field of multi-piece tire forming machines, and in particular to a pressure roller structure for a multi-piece tire forming machine. Background Technology

[0002] In the use of multi-piece tire forming machines, due to the large number of pressure roller rings, they usually need to be limited to ensure correct positioning. In the existing technology, the pressure roller rings are usually fixed with bolts and baffles. This method can effectively prevent the pressure roller rings from shifting between themselves and the piston during operation, ensuring the accuracy and stability of the forming process. However, as the equipment is used for a long time, the pressure roller rings need to be replaced regularly. The current bolt-fixed method is not convenient to disassemble. Although bolt fixing performs well in terms of fixation, disassembly requires removing each bolt one by one, and the disassembly process is cumbersome and time-consuming. After long-term use, the bolts may loosen or corrode, further increasing the difficulty of disassembly. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies. In the use of multi-piece tire forming machines, due to the large number of pressure roller rings, they usually need to be limited to ensure correct positioning. In existing technologies, the pressure roller rings are typically fixed with bolts and baffles. This method effectively prevents the pressure roller rings from shifting away from the piston during operation, ensuring the accuracy and stability of the forming process. However, as the equipment is used for longer periods, the pressure roller rings need to be replaced periodically. The current bolt-fixed method is not convenient for disassembly. Although bolt fixing performs well in terms of fixation, disassembly requires removing each bolt individually, which is cumbersome and time-consuming. After prolonged use, the bolts may loosen or corrode, further increasing the difficulty of disassembly. This invention provides a pressure roller structure for multi-piece tire forming machines.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a multi-piece tire forming machine pressure roller structure, comprising a main body, a plurality of limiting mechanisms provided on the outer surface of the main body, a supporting mechanism provided inside the limiting mechanism, a plurality of piston rods provided on one side of the main body, a plurality of air inlet pipes provided on the other side of the main body, a plurality of pressure roller rings provided on the outer surface of the main body, the limiting mechanism including a support groove formed on the outer surface of the main body, a rotating plate provided on the inner wall of the support groove, two support blocks fixedly connected to the inner wall of the support groove, two grooves formed on the outer surface of the rotating plate, a rotating groove formed on the inner wall of the groove, a rotating rod rotatably connected to the inner wall of the rotating groove, one end of the rotating rod being rotatably connected to one side of the support block;

[0005] With the above implementation scheme, after the rotating plate enters the support groove, the outer surface of the rotating plate is flush with the outer surface of the main body, which facilitates the sliding removal of the pressure roller ring from the top of the main body. At the same time, because the rotating plate is perpendicular to the main body and supported by the support mechanism, multiple pressure roller rings can be limited, so that the pressure roller rings are aligned with the piston rod. The rotating rod can protect the torsion spring, prevent the torsion spring from bending, and increase the service life of the torsion spring.

[0006] In a preferred embodiment, a torsion spring is provided on the outer surface of the rotating rod, one end of the torsion spring is fixedly connected to the inner wall of the rotating groove, and the other end of the torsion spring is fixedly connected to one side of the support block.

[0007] Through the above implementation scheme, the torsion spring can provide torque so that when the support mechanism is removed, the torsion spring can drive the rotating plate to be fixed inside the support groove, thereby preventing the rotating plate from rotating randomly and affecting the removal and installation of the pressure roller ring from the top of the main body.

[0008] In a preferred embodiment, the support mechanism includes a fixing groove formed inside the support groove, and a bracket is fixedly connected to the inner wall of the fixing groove.

[0009] Through the above implementation scheme, the bracket can support the rotation of the shaft, increasing the structural stability of the shaft. The fixing groove can accommodate the components on the support mechanism, preventing the components on the support mechanism from affecting the flatness between the rotating plate and the main body.

[0010] In one preferred embodiment, a shaft is rotatably connected to the inner wall of the bracket, a threaded tube is fixedly connected to the outer surface of the shaft, a threaded rod is threadedly connected to the inner wall of the threaded tube, and a rotating block is rotatably connected to one end of the threaded rod.

[0011] Through the above implementation scheme, the threaded tube and the threaded rod can be contracted at the threaded tube, so that the threaded rod can enter the interior of the threaded tube and enter the interior of the fixed groove through the shaft. At the same time, the rotation of the threaded rod can drive the rotating block to move to the rotating plate to support the rotating plate. After the rotating block contacts the rotating plate, the rotation of the threaded rod will not cause the rotating block to cause rotational wear on the rotating plate.

[0012] In a preferred embodiment, the support mechanism further includes a slot formed on one side of the rotating plate, the slot having an inclined surface that contacts the rotating block;

[0013] The above implementation scheme uses a slope at the slot to facilitate a complete fit between the rotating block and the slot, thereby improving the support stability of the support mechanism.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] After the rotating plate enters the support groove, its outer surface is flush with the outer surface of the main body, which facilitates the sliding removal of the pressure roller ring from the top of the main body. At the same time, the rotating plate is perpendicular to the main body and supported by the support mechanism, which can limit the multiple pressure roller rings and align them with the piston rod. The threaded tube and threaded rod can retract at the threaded tube, allowing the threaded rod to enter the interior of the threaded tube and then enter the interior of the fixed groove through the shaft. Meanwhile, the rotation of the threaded rod can drive the rotating block to move to the rotating plate to support the rotating plate. After the rotating block contacts the rotating plate, the rotation of the threaded rod will not cause the rotating block to cause rotational wear on the rotating plate. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] like Figure 1-4 As shown, this utility model provides a technical solution: a multi-piece tire forming machine pressure roller structure, including a main body 1, a plurality of limiting mechanisms 2 are provided on the outer surface of the main body 1, a supporting mechanism 3 is provided inside the limiting mechanism 2, a plurality of piston rods 6 are provided on one side of the main body 1, a plurality of air inlet pipes 5 are provided on the other side of the main body 1, a plurality of pressure roller rings 4 are provided on the outer surface of the main body 1, the limiting mechanism 2 includes a support groove 21 opened on the outer surface of the main body 1, a rotating plate 23 is provided on the inner wall of the support groove 21, two support blocks 22 are fixedly connected to the inner wall of the support groove 21, two grooves 24 are opened on the outer surface of the rotating plate 23, a rotating groove 25 is opened on the inner wall of the groove 24, a rotating rod 26 is rotatably connected to the inner wall of the rotating groove 25, one end of the rotating rod 26 is rotatably connected to one side of the support block 22, a torsion spring 27 is provided on the outer surface of the rotating rod 26, one end of the torsion spring 27 is fixedly connected to the inner wall of the rotating groove 25, and the other end of the torsion spring 27 is fixedly connected to one side of the support block 22;

[0027] Through the above embodiments, after the rotating plate 23 enters the interior of the support groove 21, the outer surface of the rotating plate 23 is flush with the outer surface of the main body 1, which facilitates the sliding removal of the pressure roller ring 4 from the top of the main body 1. At the same time, the rotating plate 23 is perpendicular to the main body 1 and is supported by the support mechanism 3, which can limit the multiple pressure roller rings 4, align the pressure roller rings 4 with the piston rod 6, and the rotating rod 26 can protect the torsion spring 27, prevent the torsion spring 27 from bending, and increase the service life of the torsion spring 27.

[0028] Furthermore, the torsion spring 27 can provide torque so that when the support mechanism 3 is removed, the torsion spring 27 can drive the rotating plate 23 to be fixed inside the support groove 21, thereby preventing the rotating plate 23 from rotating randomly and affecting the removal and installation of the pressure roller ring 4 from the top of the main body 1.

[0029] The support mechanism 3 includes a fixed groove 31 opened inside the support groove 21. A bracket 33 is fixedly connected to the inner wall of the fixed groove 31. A shaft 34 is rotatably connected to the inner wall of the bracket 33. A threaded tube 35 is fixedly connected to the outer surface of the shaft 34. A threaded rod 36 is threadedly connected to the inner wall of the threaded tube 35. A rotating block 37 is rotatably connected to one end of the threaded rod 36.

[0030] Through the above embodiments, the bracket 33 can support the rotation of the shaft 34, increasing the structural stability of the shaft 34. The fixing groove 31 can accommodate the components on the support mechanism 3, preventing the components on the support mechanism 3 from affecting the flatness between the rotating plate 23 and the main body 1. The threaded tube 35 and the threaded rod 36 can cause the threaded rod 36 to contract at the threaded tube 35, so that the threaded rod 36 can enter the interior of the threaded tube 35 and enter the interior of the fixing groove 31 through the shaft 34. At the same time, the rotation of the threaded rod 36 can drive the rotating block 37 to move to the rotating plate 23 to support the rotating plate 23. After the rotating block 37 contacts the rotating plate 23, the rotation of the threaded rod 36 will not cause the rotating block 37 to cause rotational wear on the rotating plate 23.

[0031] The support mechanism 3 also includes a slot 32 opened on one side of the rotating plate 23. The slot 32 is provided with an inclined surface, and the inclined surface contacts the rotating block 37.

[0032] Through the above embodiments, the inclined surface at the slot 32 facilitates the complete fit between the rotating block 37 and the slot 32, thereby improving the support stability of the support mechanism 3.

[0033] Working principle:

[0034] like Figure 1-4 As shown, when the pressure roller ring 4 needs to be replaced during use, the threaded rod 36 is rotated to enter the inside of the threaded tube 35, and then the threaded tube 35 is rotated around the shaft 34 to enter the inside of the fixed groove 31. At this time, the rotating plate 23 enters the inside of the support groove 21 under the action of the torsion spring 27, and then the pressure roller ring 4 can be slid out.

[0035] The new pressure roller ring 4 is slidably fitted into the outside of the main body 1. Then, the rotating plate 23 is rotated perpendicular to the main body 1. Then, the threaded tube 35 is rotated. Then, the threaded rod 36 is rotated to drive the rotating block 37 into the inside of the slot 32. Then, the angle between the rotating block 37 and the inclined surface of the slot 32 is adjusted. Then, the threaded rod 36 is rotated until the rotating block 37 is completely in contact with the inclined surface of the slot 32.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
