Description

Technical Field

[0001] The invention relates to the technical field of tire processing equipment, and in particular to a tire post-inflation device. Background Art

[0002] During the tire vulcanization process, in order to prevent the tire from deforming during the cooling process after high-temperature vulcanization, the tire that has just been high-temperature vulcanized is usually placed on a post-inflation device for cooling and shaping after inflation to ensure the shape, size and physical properties of the tire, thereby ensuring the quality of the tire.

[0003] Existing tire rear inflation devices mainly include the following two types:

[0004] One is a flip-type four-station post-inflation device, which requires more parts and has a complex structure. In addition, because the upper and lower chucks are floating structures with a large gap, it is difficult to ensure the centering of the upper and lower chucks after flipping and switching the stations, and the repeated positioning accuracy is low.

[0005] The other is a hydraulic four-station post-inflation device, which requires a hydraulic cylinder to provide support force at the axis of the chuck during inflation. Therefore, the height of the entire equipment includes the height of the upper and lower hydraulic cylinders, which occupies a large space and is inconvenient to repair and replace components such as the chuck, resulting in high maintenance costs. In addition, the four stations require four cylinders and corresponding hydraulic valve groups, which are more expensive and pose a safety hazard of hydraulic oil leakage. Summary of the invention

[0006] Based on the above problems, the purpose of the present invention is to provide a tire rear inflation device, which reduces the height of the entire device, occupies a small space, and ensures the centering of the chuck; at the same time, it also effectively solves the oil leakage problem of the existing hydraulic rear inflation device.

[0018] As a preferred embodiment of the tire post-inflation device of the present invention, each of the post-inflation stations further comprises a tire pushing assembly which is adjustably arranged on the frame, and the tire pushing assembly is used to separate the tire and the fixed chuck.

[0019] As a preferred embodiment of the tire rear inflation device of the present invention, the tire rear inflation device further comprises a tire loading and unloading robot, and the tire loading and unloading robot is used for loading or unloading the tire from the movable chuck.

[0020] As a preferred embodiment of the tire post-inflation device of the present invention, the mold adjusting assembly includes a support seat, a mold adjusting rod and a mold adjusting nut. The support seat is slidably connected to the frame, the mold adjusting nut is arranged in the support seat, and the mold adjusting rod is arranged in the mold adjusting nut.

[0046] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions.

[0048] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] like Figures 1 to 6As shown, this embodiment provides a tire post-inflation device, which can be used to inflate, cool and shape a tire 100 after high-temperature vulcanization. The tire post-inflation device includes a frame 1 and a plurality of post-inflation stations 2, each of which includes a chuck assembly 21 and a mold adjustment assembly 22. The chuck assembly 21 is used to clamp the tire 100 for post-inflation operation, and the mold adjustment assembly 22 is used to adjust the mold closing height and support the chuck assembly 21 after the inflation operation is completed. The mold adjustment assembly 22 has a first position on the frame 1 to support the chuck assembly 21 when the post-inflation operation is performed, and a second position to avoid the chuck assembly 21 after the inflation operation is completed; the mold adjustment assembly 22 can move between the first position and the second position.

[0050] Specifically, Figure 1 and Figure 2 As shown, the chuck assembly 21 includes a fixed chuck 211 and a movable chuck 212. The fixed chuck 211 is fixedly arranged on the frame 1, and the movable chuck 212 is movably arranged on the frame 1. The movable chuck 212 can be raised to clamp the tire 100 together with the fixed chuck 211. The mold adjustment assembly 22 is movably arranged on the frame 1. The mold adjustment assembly 22 can be moved to the bottom of the raised movable chuck 212 (i.e., the first position mentioned above) and adjusted to a preset mold closing height. The mold adjustment assembly 22 can also be moved to the side of the movable chuck 212 (i.e., the second position mentioned above) to avoid the lowered movable chuck 212.

[0051] When the tire 100 after high temperature vulcanization is inflated, cooled and shaped, the tire 100 is first placed on the movable chuck 212, and the movable chuck 212 is raised to clamp the tire 100 together with the fixed chuck 211, and then the mold adjustment assembly 22 is moved to the bottom of the raised movable chuck 212, and the mold adjustment assembly 22 is adjusted to a preset mold closing height according to the design requirements of the mold closing height; then, pressurized gas is filled into the tire 100, and under the action of the gas pressure, the tire 100 begins to expand and deform and generates a force applied to the movable chuck 212, so that the movable chuck 212 moves downward until it moves downward. When the tire 100 is in contact with the mold adjusting assembly 22 at the preset mold closing height, the air pressure in the tire 100 rises to the set pressure and is maintained for a period of time to complete the inflation, cooling and shaping of the tire 100; after the inflation, cooling and shaping are completed, the tire 100 is deflated, the tire 100 and the fixed chuck 211 are separated, the movable chuck 212 is raised until there is enough space for the mold adjusting assembly 22 to move out of the movable chuck 212, and then the mold adjusting assembly 22 is moved to the side of the movable chuck 212, and finally, the movable chuck 212 is lowered to the tire unloading position, and the tire 100 is removed from the movable chuck 212.

[0052] The present invention adopts a movable mold adjustment component 22. After the post-inflation operation is completed, the mold adjustment component 22 is moved from the first position to the second position to avoid the movable chuck 212 from descending to the tire unloading position. Therefore, this method reduces the height of the entire device, reduces the occupied space, and facilitates the subsequent maintenance and replacement of components such as the movable chuck 212.

[0053] Each post-inflation station 2 may further include a mobile drive 23, which is used to drive the mold adjustment assembly 22 to move between the first position and the second position on the frame 1, so that the mold adjustment assembly 22 moves to the bottom of the raised movable chuck 212, or moves the mold adjustment assembly 22 to the side of the lowered movable chuck 212. Specifically, the mobile drive 23 may be a cylinder or an electric push rod, so as to avoid the safety accident of hydraulic oil leakage caused by hydraulic drive. Two mobile drives 23 may be symmetrically arranged to ensure the smooth movement of the mold adjustment assembly 22, thereby ensuring the mold adjustment accuracy of the mold adjustment assembly 22, and at the same time making full use of the limited installation space on the frame 1.

[0054] Optionally, the chuck assembly 21 further includes a lifting drive 213, which is used to drive the movable chuck 212 to rise and fall, so that the movable chuck 212 rises to clamp the tire 100 together with the fixed chuck 211, or the movable chuck 212 falls to the side of the mold adjustment assembly 22. Specifically, the lifting drive 213 can be a cylinder or an electric push rod, which avoids the safety accident of hydraulic oil leakage caused by hydraulic drive. The lifting drive 213 can be arranged between the two mobile drives 23 to make full use of the limited installation space on the frame 1. Two lifting drives 213 can be symmetrically arranged to ensure the smooth lifting and lowering of the movable chuck 212, thereby ensuring the centering accuracy of the movable chuck 212 and the fixed chuck 211.

[0055] like Figures 3 to 6As shown, the mold adjustment assembly 22 may include a support seat 221, a mold adjustment rod 222 and a mold adjustment nut 223. The support seat 221 is slidably connected to the frame 1, the mold adjustment nut 223 is arranged in the support seat 221, and the mold adjustment rod 222 is arranged in the mold adjustment nut 223. Rotating the mold adjustment rod 222 can drive the mold adjustment nut 223 to extend out of the support seat 221, so that the mold adjustment nut 223 extends to a preset mold clamping height. In one embodiment, the mold adjustment rod 222 is rotatably arranged in the support seat 221, the mold adjustment nut 223 can be threadedly connected with the mold adjustment rod 222, and is slidably connected in the support seat 221. Rotating the mold adjustment rod 222 can drive the mold adjustment nut 223 to extend out of the support seat 221, so that the mold adjustment nut 223 extends to a preset mold clamping height. The interior of the support seat 221 and the mold adjusting nut 223 are both hollow cylindrical structures, the mold adjusting rod 222 is located in the hollow cylindrical structure of the mold adjusting nut 223, and the mold adjusting nut 223 is located in the hollow cylindrical structure of the support seat 221. The mold adjusting nut 223 is threadedly connected with the support seat 221. The mold adjusting nut 223 and the mold adjusting rod 222 form a screw nut pair. Under the limiting effect of the support seat 221, the mold adjusting nut 223 cannot rotate and can only be lifted and lowered. When adjusting the mold closing height, the mold adjusting rod 222 can be rotated manually or automatically, and the mold adjusting rod 222 drives the mold adjusting nut 223 to extend out of the support seat 221, so that the upper end surface of the mold adjusting nut 223 reaches the preset mold closing height. When the tire 100 is inflated, it expands and deforms, and the movable chuck 212 is moved downward until the tire 100 is in contact with the upper end surface of the mold adjusting nut 223. At this time, the air pressure in the tire 100 rises to the set air pressure, and the inflation is completed.

[0056] In another embodiment, the die-adjusting nut 223 and the die-adjusting rod 222 may be connected by a keyway structure, that is, the die-adjusting nut 223 and the die-adjusting rod 222 may slide relative to each other in the axial direction, but under the limiting effect of the keyway structure, the die-adjusting nut 223 and the die-adjusting rod 222 cannot rotate relative to each other in the circumferential direction, and the die-adjusting nut 223 is threadedly connected to the support seat 221. When the die-adjusting rod 222 is rotated, the die-adjusting rod 222 drives the die-adjusting nut 223 to rotate. Since the die-adjusting nut 223 and the support seat 221 form a screw nut pair, the die-adjusting nut 223 may move up and down relative to the die-adjusting rod 222, thereby extending out of the support seat 221. In addition, the die-adjusting rod 222 may be a rod-shaped structure with a non-circular cross section such as a rectangle or a triangle to prevent the die-adjusting nut 223 and the die-adjusting rod 222 from rotating relative to each other in the circumferential direction. In this case, there is no need to use a keyway structure to connect the die-adjusting nut 223 and the die-adjusting rod 222.

[0057] Specifically, for the convenience of disassembly and maintenance, the support seat 221 includes a first support seat 2211 and a second support seat 2212, the first support seat 2211 is slidably connected to the frame 1, the movable driving member 23 is connected to the first support seat 2211, one end of the second support seat 2212 is fixedly connected to the first support seat 2211, and the other end is used to support the tire 100 through the movable chuck 212, the mold adjustment rod 222 is rotatably arranged on the first support seat 2211, and the mold adjustment nut 223 is slidably connected to the second support seat 2212. When the tire 100 is inflated, it expands and deforms, and the pressure of the tire 100 is transmitted to the frame 1 through the movable chuck 212, the mold adjustment nut 223, the second support seat 2212 and the first support seat 2211.

[0058] Optionally, the mold adjustment assembly 22 further includes a mold adjustment driving member 224, which is used to drive the mold adjustment rod 222 to rotate, so that the rotating mold adjustment rod 222 drives the mold adjustment nut 223 to extend out of the support seat 221. Since the mold adjustment driving member 224 adopts a servo motor, it is convenient to accurately control the rotation angle of the mold adjustment rod 222, ensure the mold clamping accuracy, and the driving method is simple and efficient, without the need to set up complex hydraulic and pneumatic pipelines. The mold adjustment assembly 22 also includes a coupling 225, and the mold adjustment driving member 224 is connected to the mold adjustment rod 222 through the coupling 225. The coupling 225 can be used as a safety device to prevent the mold adjustment rod 222 from bearing excessive loads and play a role in overload protection. The mold adjustment assembly 22 also includes a first slide 226, and a first slide rail 11 is provided on the frame 1. The support seat 221 is slidably connected to the first slide rail 11 through the first slide 226.

[0059] In order to ensure the concentricity of the movable chuck 212 and the fixed chuck 211, the chuck assembly 21 may further include a guide assembly 214, which is used to guide the lifting and lowering movement of the movable chuck 212, thereby ensuring the centering of the movable chuck 212 and the fixed chuck 211, avoiding the deformation of the tire mouth and affecting the quality of the tire 100, and ensuring the shape, size and physical properties of the tire 100. The number and position of the guide assembly 214 are not limited, and the guide assembly 214 may be provided with one, or two or more. In this embodiment, two guide assemblies 214 are symmetrically arranged between the movable chuck 212 and the frame 1.

[0060] In this embodiment, the guide assembly 214 includes a guide rod 2141 and a guide seat 2142 that are slidably connected, the guide rod 2141 is fixedly connected to the movable chuck 212, and the guide seat 2142 is fixedly connected to the frame 1. In order to reduce friction resistance, optionally, the guide rod 2141 is an optical axis, the guide seat 2142 is a linear bearing, and the optical axis moves through the linear bearing. In other embodiments, the guide assembly 214 can also adopt a guide structure in which a guide rail and a slider cooperate.

[0061] like Figure 2 As shown, each post-inflation station 2 may further include a tire pushing assembly 24 which is adjustably arranged on the frame 1, and the tire pushing assembly 24 is used to separate the tire 100 and the fixed chuck 211. In this embodiment, the tire pushing assembly 24 includes a tire pushing drive 241, a tire pushing slide 242, a tire pushing rail 243, a locking knob 244 and a mounting plate 245, two mounting plates 245 are arranged on the frame 1 at intervals, and the tire pushing rail 243 is erected between the two mounting plates 245. The tire pushing drive 241 can be a cylinder or an electric push rod, which avoids the safety accident of hydraulic oil leakage caused by hydraulic drive. The tire pushing slide 242 is slidably sleeved on the tire pushing rail 243, and the tire pushing drive 241 is installed on the tire pushing slide 242, and the tire 100 is supported by the cylinder rod of the tire pushing drive 241, so as to separate the tire 100 and the fixed chuck 211. The locking knob 244 is threadedly connected to the tire pushing slide 242. By rotating the locking knob 244, it is made to abut against the tire pushing slide rail 243 to generate friction resistance, thereby locking the tire pushing slide 242 and the tire pushing slide rail 243, so that the tire pushing slide 242 cannot continue to slide, thereby adjusting the position of the tire pushing drive member 241 on the frame 1 to accommodate the separation of tires 100 of various specifications from the fixed chuck 211.

[0062] like Figure 1 and Figure 2 As shown, optionally, the tire post-inflation device further includes a tire loading and unloading manipulator 3, which is used to load or unload the tire 100 from the movable chuck 212. In this embodiment, four post-inflation stations 2 are arranged on the frame 1, and a second slide rail 12 is provided on the frame 1. The tire loading and unloading manipulator 3 is slidably arranged on the second slide rail 12. The inflation operation of the four stations is realized by one tire loading and unloading manipulator 3, which reduces the processing cost and improves the inflation efficiency.

[0063] In this embodiment, the tire loading and unloading robot 3 includes a robot arm 31, a clamping plate 32, a second slide 33, a rotating shaft 34 and a robot driving member 35. The second slide 33 is slidably arranged on the second slide rail 12, and the rotating shaft 34 is rotatably mounted on the second slide 33. One end of the robot arm 31 is connected to the clamping plate 32, and the other end is connected to the rotating shaft 34. The robot driving member 35 is mounted on the second slide 33, and is used to drive the rotating shaft 34 to rotate, and drive the robot arm 31 and the clamping plate 32 to rotate to the corresponding rear inflation station 2. The robot driving member 35 can be a motor, which is convenient for accurately controlling the rotation angle of the rotating shaft 34.

[0064] The working process of the tire post-inflation device provided in this embodiment is roughly as follows: when the tire 100 after high-temperature vulcanization is inflated, cooled and finalized, the tire 100 is first placed on the movable chuck 212 by the tire loading and unloading robot 3, and the movable chuck 212 is raised by the lifting drive member 213 to clamp the tire 100 together with the fixed chuck 211, and then the mold adjustment component 22 is moved to the bottom of the raised movable chuck 212 by the moving drive member 23, and the mold adjustment component 22 is adjusted to the preset mold height according to the mold height design requirements. Specifically, the mold adjustment rod 222 is driven to rotate by the mold adjustment drive member 224, and the mold adjustment rod 222 drives the mold adjustment nut 223 to extend out of the support seat 221, so that the mold adjustment nut 223 extends to the preset mold height; pressurized gas is filled into the tire 100, and the tire 100 begins to expand and deform. And generate a force to be applied to the movable chuck 212, so that the movable chuck 212 moves downward until the tire 100 is in contact with the upper end surface of the mold adjusting nut 223. At this time, the air pressure in the tire 100 rises to the set air pressure and is maintained for a period of time to complete the inflation, cooling and shaping of the tire 100; after the inflation, cooling and shaping are completed, the tire 100 is deflated, and the tire 100 and the fixed chuck 211 are separated by the tire pushing drive 241, and the movable chuck 212 is lifted by the lifting drive 213 until there is enough space for the mold adjusting assembly 22 to move out of the movable chuck 212, and then the mold adjusting assembly 22 is moved to the side of the movable chuck 212 by the moving drive 23, and finally, the movable chuck 212 is lowered to the tire unloading position by the lifting drive 213, and the tire 100 is removed from the movable chuck 212 by the tire loading and unloading robot 3.
