[0041] Before explaining any embodiment of the present application in detail, it should be understood that the present application is not limited to the structural details and component arrangements described in the following description or shown in the above drawings.

[0042] In the present application, the terms "include", "comprise", "have" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the phrase "including one..." does not exclude the presence of additional identical elements in the process, method, article or device including that element.

[0043] In this application, the term "and / or" describes the relationship between associated objects and indicates that three relationships can exist. For example, a centrifugal vortex magnetic pump and / or a centrifugal vortex magnetic pump can represent three situations: the separate existence of a centrifugal vortex magnetic pump, the simultaneous existence of a centrifugal vortex magnetic pump and a centrifugal vortex magnetic pump, and the separate existence of a centrifugal vortex magnetic pump. Additionally, in this application, the character " / " generally indicates that the associated objects before and after are in an "and / or" relationship.

[0044] In this application, the terms "connected", "combined", "coupled", and "installed" can be direct connections, combinations, couplings, or installations, or they can be indirect connections, combinations, couplings, or installations. Among them, for example, a direct connection means that two parts or components are connected together without the need for an intermediate component, and an indirect connection means that two parts or components are respectively connected to at least one intermediate component, and these two parts or components are connected through the intermediate component. In addition, "connected" and "coupled" are not limited to physical or mechanical connections or couplings and can include electrical connections or couplings.

[0045] In this application, those of ordinary skill in the art will understand that relative terms used in combination with a quantity or condition (such as "about", "approximately", "substantially", etc.) are intended to include the stated value and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances resulting from manufacturing, assembly, use, etc. associated with a particular value. Such terms should also be considered to disclose a range defined by the absolute values of two endpoints. A relative term can refer to a plus or minus a certain percentage (such as 1%, 5%, 10% or more) of the indicated value. A numerical value without a relative term should also be disclosed as a particular value with a tolerance. In addition, when expressing a relative angular positional relationship (such as substantially parallel, substantially perpendicular), "substantially" can refer to a plus or minus a certain number of degrees (such as 1 degree, 5 degrees, 10 degrees or more) based on the indicated angle.

[0046] In this application, those of ordinary skill in the art will understand that the functions performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the functions performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0047] In this application, the orientation terms such as "upper", "lower", "left", "right", "front", and "back" are described based on the orientation and positional relationship shown in the drawings, and should not be construed as a limitation on the embodiments of this application.

It should also be understood that the orientation terms such as the upper side, the lower side, the left side, the right side, the front side, and the back side not only represent the positive orientation, but can also be understood as the side orientation. For example, the lower side can include directly below, lower left, lower right, lower front, and lower back, etc.

[0048] Please refer to Figures 1 to 3 , this embodiment provides a rear inflation device, which includes a frame body 100, an upper crossbeam mechanism 200, and a lower crossbeam mechanism 300. The lower crossbeam mechanism 300 is arranged on the frame body 100, and the upper crossbeam mechanism 200 and the lower crossbeam mechanism 300 can cooperate with each other to inflate the tire. The rear inflation device further includes a lead screw 1, a driving nut 2, a driving component 3, and a limiting component 4. The lead screw 1 is slidably arranged on the frame body 100 in the vertical direction, and the upper crossbeam mechanism 200 is arranged at the lower end of the lead screw 1. The driving nut 2 is rotatably arranged on the frame body 100 and is in threaded cooperation with the lead screw 1. The driving component 3 is arranged on the frame body 100, and the driving component 3 is configured to drive the driving nut 2 to rotate forward and backward to drive the lead screw 1 to move up and down. The limiting component 4 is arranged on the frame body 100, and the limiting component 4 is configured to limit the rotation of the driving nut 2.

[0049] In practical applications, first place the tire on the lower crossbeam mechanism 300, then the driving component 3 drives the driving nut 2 to rotate to drive the lead screw 1 to descend, and then the lead screw 1 drives the upper crossbeam mechanism 200 to descend. After the upper crossbeam mechanism 200 is in a working position where it can cooperate with the lower crossbeam mechanism 300 to inflate the tire, the limiting component 4 limits the rotation of the driving nut 2. Subsequently, the upper crossbeam mechanism 200 and the lower crossbeam mechanism 300 cooperate with each other to inflate the tire. After vulcanization is completed, the limiting component 4 cancels the limitation on the driving nut 2, and the driving component 3 drives the driving nut 2 to rotate in the reverse direction to drive the upper crossbeam mechanism 200 to reset.

[0050] It can be understood that through the transmission structure composed of the lead screw 1 and the driving nut 2, compared with the hydraulic transmission method in the prior art, it will not affect the stability and safety due to reasons such as oil leakage and pipe bursting, so that the stability and safety of the rear inflation device are better, and thus the safety hazards in the tire production process can be avoided. It should be noted that both the upper crossbeam mechanism 200 and the lower crossbeam mechanism 300 are well-known prior arts to those skilled in the art, so they will not be elaborated here.

[0051] Preferably, the driving assembly 3 includes a transmission gear 31, a driving gear 32 and a driving member 33. The transmission gear 31 is coaxially arranged on the driving nut 2. The driving gear 32 is rotatably arranged on the frame body 100, and the transmission gear 31 meshes with the driving gear 32. The driving member 33 is arranged on the frame body 100, and the driving member 33 is configured to drive the driving gear 32 to rotate forward and backward. It can be understood that the gear transmission structure composed of the transmission gear 31 and the driving gear 32 can make the structure of the driving assembly 3 more compact, with high transmission efficiency and high transmission accuracy.

[0052] Further, the driving member 33 is a servo motor, and the driving gear 32 is sleeved on the output shaft of the servo motor. It can be understood that using a servo motor to drive the driving gear 32 to rotate is energy-efficient and stable in operation. It should be noted that the model of the servo motor is selected according to the actual application scenario, and this embodiment does not make specific requirements and limitations on this. It should also be noted that in other embodiments, the driving member 33 can also adopt any mechanism with a rotational driving function in the prior art, which will not be elaborated here.

[0053] Preferably, the limiting assembly 4 includes a limiting hole 41, a limiting rod 42 and a power member 43. The limiting hole 41 is arranged on the transmission gear 31. The limiting rod 42 is slidably arranged on the frame body 100 in the vertical direction, and the lower end of the limiting rod 42 can be inserted into the limiting hole 41. The power member 43 is arranged on the frame body 100, and the power member 43 is configured to drive the limiting rod 42 to move up and down. With such a setting, inserting the lower end of the limiting rod 42 into the limiting hole 41 can limit the rotation of the driving nut 2, with a simple structure and low use cost.

[0054] It should be added that any angle of rotation of the driving nut 2 can correspondingly drive the lead screw 1 to move up and down a certain distance, that is, any angle of rotation of the driving nut 2 can drive the upper crossbeam mechanism 200 to move up and down a certain distance. Therefore, in order to accurately limit the upper crossbeam mechanism 200 to a preset working position, in this embodiment, a plurality of limiting holes 41 are provided, and the plurality of limiting holes 41 are evenly distributed around the axis of the transmission gear 31 on the circumferential side of the transmission gear 31.

[0055] To improve the convenience of inserting the lower end of the limiting rod 42 into the limiting hole 41, the lower end of the limiting rod 42 is chamfered to form a guiding surface. Of course, in other embodiments, setting a guiding surface at the orifice of the limiting hole 41 can also achieve the same function, which will not be elaborated in this embodiment.

[0056] Further, the power component 43 is a cylinder, the telescopic part of the cylinder moves in the vertical direction, and the upper end of the limiting rod 42 is connected to the telescopic part. It can be understood that driving the limiting rod 42 by the cylinder has a simple structure and low use cost. It should be noted that in other embodiments, the power component 43 can adopt any linear driving mechanism in the prior art, such as an electric cylinder, a linear module, etc.

[0057] To improve the smoothness of the sliding of the upper crossbeam mechanism 200, the post-inflation device further includes a guiding assembly 5. The guiding assembly 5 is arranged on the frame body 100 and is configured to guide the lifting of the upper crossbeam mechanism 200. Specifically, the guiding assembly 5 includes a sliding sleeve 51 and a sliding rod 52. The sliding sleeve 51 is arranged on the frame body 100. The sliding rod 52 is in sliding fit with the sliding sleeve 51, and the lower end of the sliding rod 52 is connected to the upper crossbeam mechanism 200.

[0058] This embodiment further provides a tire production device, which includes the above-mentioned post-inflation device and a transfer mechanism. The transfer mechanism is configured to supply tires to the post-inflation device. It can be understood that the tire production device including the post-inflation device has better stability and safety, and thus can avoid potential safety hazards in the tire production process.

[0059] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
