[0032] The embodiments of the present utility model are described below in conjunction with the accompanying drawings.
[0033] First, refer to Figure 2 The utility model proposes a tire inflation device 100, which includes a hollow rotating shaft 110, a ventilation joint 120 and a rotating mechanism; the hollow rotating shaft 110 includes a first end 111 and a second end 112 that are arranged opposite to each other, and a gas channel D is formed inside the hollow rotating shaft 110; the first end 111 is drivingly connected to the rotating mechanism, and the first end 111 is axially closed and radially provided with an air hole E; the second end 112 is drivingly connected to the tire, and the second end 112 is communicated with the inner cavity of the tire; the ventilation joint 120 is sealingly sleeved on the first end 111, and has a cavity communicating with the air hole E inside the hollow rotating shaft 110, and radially provides an air pipe interface I communicating with the cavity.
[0034] In the utility model, the hollow shaft 110 is radially provided with air holes E, and the cavity of the vent joint 120 is used for ventilation, thereby changing the way in which the studded equipment inflates the tire, eliminating the reliance on the right-angle hollow reducer 180, and reducing the equipment procurement cost. Furthermore, the inner diameter of the hollow shaft 110 will not be restricted by the narrow channel of the right-angle hollow reducer 180, which is conducive to quickly inflating the tire and increasing production efficiency.
[0035] In actual use, the tire is arranged upright, and a set of the tire inflation device 100 can be respectively arranged on the left and right sides of the tire, wherein the second end 112 of the hollow rotating shaft 110 of the tire inflation device 100 can be sealed against the side of the tire by connecting an adapter, so that the tire inflation devices 100 on the left and right sides can clamp and rotate the tire to facilitate the stapling of the tire circumference with the stapling machine; the tire inflation devices 100 on the left and right sides can inflate the tire at the same time, and can also be set to inflate the tire only through the tire inflation device 100 on one side.
[0036] In addition, the tire inflation device 100 can be set only on one side of the tire, and an auxiliary clamping rotating part can be set on the other side of the tire. Specifically, it can be an active rotating part or a driven rotating part, which rotates with the tire, but needs to seal and clamp the side of the tire. Its structure can refer to the rim setting that is compatible with the tire.
[0037] It should be noted that after the studding is completed, the tire can also be deflated through the tire inflation device 100 to facilitate the removal of the tire for studding of subsequent tires; the inner diameter of the hollow shaft 110 is not limited by the right-angle hollow reducer 180, which can also make the deflation process faster and improve production efficiency.
[0038] It can be understood that the tire inflation device 100 proposed in the utility model is not only used in the tire studding process, but can also be applied to any process in which the tire circumference is processed and a certain tire pressure is required in the tire.
[0039] In some embodiments, reference Figure 1 and Figure 2 , the tire inflation device 100 further includes a frame 130, a support sleeve 140 and a bearing assembly; the frame 130 is equipped with a support sleeve 140 and a rotating mechanism; the support sleeve 140 is sleeved on the outside of the hollow rotating shaft 110, and a bearing assembly is provided between the support sleeve 140 and the hollow rotating shaft 110. In some embodiments, the bearing assembly includes at least two bearings A, and the two bearings A are sleeved on the first end 111 and the second end 112 of the hollow rotating shaft 110, respectively. In some embodiments, the bearing A located at the first end 111 is a deep groove ball bearing, and the bearing A located at the second end 112 is a turntable bearing. In some embodiments, the tire inflation device 100 further includes a rotary encoder 150, which is sleeved on the hollow rotating shaft 110, and the rotary encoder 150 is in communication connection with the control system. In some embodiments, a retaining ring B is also sleeved on the hollow rotating shaft 110, and the retaining ring B and the ventilation joint 120 limit the axial position of the rotary encoder 150. In some embodiments, the retaining ring B is an elastic retaining ring for a shaft, and the elastic retaining ring for a shaft is located between the deep groove ball bearing and the rotary encoder 150 .
[0040] It should be noted that the rotary encoder 150 is a device that converts rotary motion into electrical signals, which can detect the rotation direction, speed and position of the hollow shaft 110 and feed back to the control system to achieve coordination with the motion module of the nail setting machine. The rotary encoder 150 can also adjust the coordination clearance between its own rotating end and the fixed end by setting an encoder grinding plate of appropriate thickness.
[0041] In some embodiments, reference Figure 2 , Figure 3 and Figure 4The tire inflation device 100 further includes a sealing end cap 160, which is sealingly sleeved on the second end 112 of the hollow shaft 110, and the sealing end cap 160 is sealingly connected to one end of the support sleeve 140; the venting joint 120 is sealingly connected to the other end of the support sleeve 140, and a dustproof and closed space F is formed between the venting joint 120, the sealing end cap 160, the support sleeve 140 and the hollow shaft 110. In some embodiments, the cavity of the venting joint 120 includes a circumferentially distributed guide ring groove G; the air pipe interface I, the guide ring groove G, the air hole E and the gas channel D constitute an air flow path; the hollow shaft 110 is sleeved with sealing rings C on both sides of the axial direction of the air hole E, and a avoidance groove H matching the sealing ring C is provided inside the venting joint 120. In some embodiments, the sealing ring C is a shaft-use gray ring.
[0042] In the above embodiment, there is a fitting gap between the support sleeve 140 and the hollow rotating shaft 110, and the sealing end cover 160 and the ventilation joint 120 respectively seal the fitting gap to form a dustproof and enclosed space F; in some embodiments, the deep groove ball bearing, the turntable bearing and the rotary encoder 150 are all arranged in the dustproof and enclosed space F; the setting of the dustproof seal can ensure the smooth and precise rotation of the hollow rotating shaft 110, and will not affect the normal use of the deep groove ball bearing, the turntable bearing and the rotary encoder 150. In addition, in some embodiments, the air pipe interface I of the ventilation joint 120 can be a threaded interface and is connected to an external air source. The air flow enters the guide ring groove G from the air pipe interface I. The two sides of the guide ring groove G are sealed with Gly rings through the shaft. The guide ring groove G is circumferentially distributed in a section of the hollow rotating shaft 110 where the air hole E is opened. Therefore, no matter where the air hole E rotates with the hollow rotating shaft 110, the air flow entering the guide ring groove G will enter the air channel D of the hollow rotating shaft 110 through the air hole E and finally enter the tire.
[0043] In some embodiments, reference Figure 1 The rotating mechanism includes a motor 170, a reducer 180 and a coupling 190; the motor 170 is drivingly connected to the reducer 180, and the reducer 180 is drivingly connected to the first end 111 of the hollow rotating shaft 110 through the coupling 190; a plug is installed inside the coupling 190, and the plug blocks the axial opening of the first end 111. In some embodiments, the output shaft of the motor 170, the input shaft of the reducer 180, the output shaft of the reducer 180 and the hollow rotating shaft 110 are located on the same axis.
[0044] In the above embodiment, there is no need to use a right-angle hollow reducer, which reduces costs, improves rotation accuracy, is less restricted, and is flexible to use. In addition, the motor 170 may not be coaxial with the reducer 180, but may be driven to rotate by other means, which also falls within the scope of protection of the present utility model, for example, the power shafts of the motor 170 and the reducer 180 are arranged in parallel, and two transmission wheels and a conveyor belt are added to achieve transmission connection.
[0045] In a second aspect, the present invention further provides a tire studding device, which includes the tire inflation device 100 of the first aspect.
[0046] Specifically, the tire studding device of the second aspect includes the tire inflation device 100 of the first aspect, so the tire studding device of the second aspect has at least all the technical effects of the tire inflation device 100 of the first aspect, and the technical effects of the tire inflation device 100 are not repeated here.
[0047] It can be understood that the embodiments of the present invention only propose the structure of the tire studding device related to the improvement points of the present invention, but it does not mean that the tire studding device in the present invention does not have other structures. For example, the tire studding device also includes a studding gun, a studding machine motion module, etc. Other structures will not be described one by one here.
[0048] In particular, the term "and / or" in the present invention should be understood as follows:
[0049] In the first case, the term "and / or" located between a first subject and a second subject includes any one of the following meanings: (1) only the first subject; (2) only the second subject; and (3) the first subject and the second subject.
