[0022] This utility model discloses a solid tire opener, which can flexibly adapt to solid tires of different specifications and significantly improve tire removal efficiency.
[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0025] The following is for reference. Figure 1 This invention describes a solid tire opener in an embodiment of the present invention.
[0026] This application discloses a solid tire opener, including: a cylinder 1, an adjustable sector-shaped support structure 3, and a handle 2.
[0027] The handle 2 is fixedly installed on the upper part of the cylinder 1; the adjustable sector support structure 3 includes a threaded sleeve 31, a first sector support plate 32 and a second sector support plate 33. The threaded sleeve 31 is fixedly installed on the lower end of the cylinder 1 and sleeved on the piston rod of the cylinder 1. The center of the first sector support plate 32 and the second sector support plate 33 are both provided with threaded holes. The first sector support plate 32 and the second sector support plate 33 are sequentially screwed onto the threaded sleeve 31 through the threaded holes, and both can move up and down along the threaded sleeve 31. The size of the first sector support plate 32 is larger than the size of the second sector support plate 33.
[0028] Currently, in the tire production process, after vulcanization, tires need to be removed from the mold. A tire opener is used to remove the tire from the mold. The tire opener works by using a tire-removing component to engage with a pre-drilled hole in the mold. Once engaged, a cylinder or hydraulic cylinder provides power to push or pull the tire out of the mold. Existing tire openers often only have a single-sized tire-removing component. However, in actual production, manufacturers often produce tires of various sizes, resulting in different pre-drilled hole sizes in the molds for different tire sizes. Therefore, different tire sizes require tire openers of corresponding sizes for removal from their respective molds, leading to low tire removal efficiency. Furthermore, in practice, the same tire opener may be used to remove tires of different sizes, significantly increasing the possibility of tire damage during the removal process.
[0029] In this embodiment, the tire opener is provided with a first sector-shaped support plate 32 and a second sector-shaped support plate 33 of different sizes. Both the first sector-shaped support plate 32 and the second sector-shaped support plate 33 are screwed onto the threaded sleeve 31. By rotating and adjusting the position of the first sector-shaped support plate 32 and the second sector-shaped support plate 33 on the threaded sleeve 31, it can adapt to the inner hole of different molds, ensuring good cooperation between the tire opener and the mold during the tire removal process. This not only improves the tire removal efficiency but also ensures the safety of the tire during the tire removal process. For example, when the second sector-shaped support plate 33 needs to be used, the first sector-shaped support plate 32 can be manually rotated to the top of the threaded sleeve 31, moving it away from the second sector-shaped support plate 33, thereby adjusting the second sector-shaped support plate 33 to a suitable position.
[0030] Furthermore, the design of the adjustable sector support structure 3 enables the cylinder 1 tire opener of this application to be applicable to molds of various specifications. Compared with the prior art, there is no need to replace different models of tire openers for different molds, which greatly improves the versatility and practicality of the equipment.
[0031] In addition, the tire opener in this embodiment has a simple structure and is easy to operate. It is also equipped with a handle 2, which makes it easy to pick up and easy to master.
[0032] In some embodiments, for example Figure 1 As shown, both the first sector-shaped support plate 32 and the second sector-shaped support plate 33 include a support body and sector-shaped plates. Multiple sector-shaped plates are provided, spaced apart and arranged circumferentially on the support body. Threaded holes are formed on the support body. The size of the sector-shaped plates can be designed according to the inner hole dimensions of different molds, ensuring that the sector-shaped plates can fit tightly against the inner hole of the mold, providing effective support and facilitating the pulling of the tire out of the mold.
[0033] In some embodiments, the length of the threaded sleeve 31 is less than the length of the piston rod.
[0034] Furthermore, the solid tire opener also includes a fan-shaped fixing base 4, for example... Figure 1 As shown, the sector-shaped fixing base 4 includes a base body and sector-shaped plates. Multiple sector-shaped plates are spaced apart and arranged circumferentially on the base body. The sector-shaped fixing base 4 is fixedly installed at the bottom of the piston rod and can move up and down with the piston rod. The sector-shaped fixing base 4 mainly serves as an auxiliary support. Its design, with a relatively small sector shape, provides additional support to the cylinder 1 body when the piston rod extends and retracts. This effectively ensures the stability of the tire removal process, allowing the piston rod's pulling force to be accurately transmitted to the solid tire, thus achieving non-destructive tire removal and improving product quality.
[0035] In some embodiments, the cylinder wall of the cylinder 1 is provided with an air inlet and an air outlet, and both the air inlet and the air outlet are provided with connecting hoses 5. The connecting hoses 5 are provided to facilitate connection with the air inlet and outlet pipes of an external air source.
[0036] Furthermore, the outer layer of the connecting hose 5 is provided with a protective layer, which can effectively prevent air leakage.
[0037] In some embodiments, the handle 2 is connected to the upper part of the cylinder 1 via a flange 6.
[0038] In some embodiments, the threaded sleeve 31 is connected to the lower part of the cylinder 1 via a flange 6.
[0039] The specific usage process of the tire opener in this application is as follows:
[0040] After the solid tire has vulcanized in the mold, open the upper mold and place the tire opener into the center of the lower mold's steel ring, aligning the piston rod's extension direction with the solid tire's removal position. Depending on the mold's inner diameter, use either the first sector-shaped support plate 32 or the second sector-shaped support plate 33, sliding it downwards along the threaded sleeve 31 into the mold. Rotate and adjust the sector-shaped support plate to lock it into place within the inner diameter. The operator activates the external air supply, and the piston rod continues to penetrate until the sector-shaped fixing base 4 reaches the designated position within the mold. Rotate the handle 2 to ensure the sector-shaped fixing base 4 fits tightly against the mold and remains horizontal and stable.
[0041] When the control valve is opened, the piston rod retracts. However, because the sector-shaped fixed base 4 is tightly fitted with the mold, the piston rod cannot retract. As the cylinder 1 increases its retraction force, the sector-shaped support plate moves the lower steel ring upward, gradually pulling the solid tire out of the mold.
[0042] Once the solid tire is completely removed from the mold, rotate the fan-shaped support plate to detach it from the inner hole. The piston rod then drives the fixed base to detach from the mold, completing the solid tire removal operation.
[0043] The tire opener in this embodiment, through its adjustable support structure design, effectively solves the problem of poor adaptability of the existing cylinder 1 tire opener to different molds, improves the automation level, production efficiency and product quality of tire production, and has broad application prospects and market value.
