[0002] The vulcanizer, a device that converts green tires into finished tires, is a crucial step in the tire production process. After vulcanization, the tire, which still has a high carcass temperature, is promptly inflated, cooled, and shaped to maintain correct tire dimensions and physical properties and prevent deformation. The post-inflation device, a crucial component of the tire vulcanizer, is primarily responsible for inflating, cooling, and shaping the vulcanized tire. Its structure directly impacts the vulcanizer's production cost and vulcanization quality.

[0003] At present, most of the devices for inflating automobile tires are mechanical structures, which require manual judgment to determine whether the size of the filling pressure meets the requirements of the automobile tire, so as to stabilize the tire pressure and prevent the tire from bursting. Due to the manual monitoring, there are certain errors. Therefore, there is an urgent need to provide a tire inflation circumference measuring device. Summary of the Invention

[0028] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0029] The present invention provides a tire inflation circumference measuring device. It uses a laser sensor to measure the tire's diameter during inflation to calculate the tire's circumference, thereby determining the degree of inflation and monitoring the tire's inflation status in real time. When the tire diameter increases to a preset range, inflation is stopped in a timely manner. Figure 1-3 , including a base frame 100, a bracket 200, an adjustment component 300 and a contact sensor 400;

[0030] Please continue reading Figure 1 and Figure 3, as the base connection chassis 100, the chassis 100 is slidably connected with an adjustable telescopic plate 120 (the adjustable telescopic plate structure is similar to the telescopic rod structure, and the two side plates are connected by a telescopic structure). One end of the adjustable telescopic plate 120 is fixedly connected by a connecting bolt and cannot be moved. The end of the chassis 100 is connected to a telescopic cylinder 110. The telescopic end of the telescopic cylinder 110 is connected to one end of the adjustable telescopic plate 120. The telescopic cylinder 110 drives the length of the adjustable telescopic plate 120 to change, thereby adjusting the length of the overall supporting base, which can adapt to tire measurement and monitoring of different wheel diameters;

[0031] Please continue reading Figure 1-2 , there are two groups of brackets 200, and the two groups of brackets 200 are respectively set corresponding to the top of both ends of the adjustable telescopic plate 120;

[0032] A connecting groove 210 is formed in the bracket 200, and a sliding groove 211 is formed on the outside of the bracket 200 and is connected to the connecting groove 210;

[0033] Please continue reading Figure 1-3 There are two groups of adjustment components 300, and the two groups of adjustment components 300 are set in a one-to-one correspondence with the bracket 200 to change the height of the laser sensor 331 to adapt to the measurement of tires with different wheel diameters;

[0034] The adjustment assembly 300 includes a motor 310 threadedly connected to the top of the bracket 200. The output end of the motor 310 is connected to a threaded rod 311. A threaded sleeve 320 is threadedly mounted on the threaded rod 311 (because the threaded sleeve is threadedly engaged with the threaded rod and the rotation direction of the threaded sleeve is restricted by the slide groove and the slide seat, the threaded sleeve performs a thread feed action when the threaded rod rotates). The outer side of the threaded sleeve 320 is integrally connected to a slide seat 321 that slides with the slide groove 211. The outer side of the slide seat 321 is threadedly connected to a connecting frame 330. A laser sensor 331 is threadedly mounted on the connecting frame 330.

[0035] action:

[0036] The motor 310 drives the threaded rod 311 to rotate within the connecting groove 210, causing the threaded sleeve 320 to perform a threaded feed motion along the outer side of the threaded rod 311, thereby driving the position of the laser sensor 331 to change. The height of the laser sensor 331 is adjusted to adapt to the measurement of tires with different wheel diameters.

[0037] The measurement formula is as follows:

[0038]

[0039] C is the tire circumference, d1 is the diameter measured by the laser sensor on the left side of the tire, d2 is the diameter measured by the laser sensor on the right side of the tire, π is the circumference, v is the inflation rate, and △t is the sampling time interval;

[0040] The laser sensor 331 is used to measure the increasing diameter of the tire during the inflation process to calculate the circumference of the tire due to inflation, thereby judging the degree of inflation and monitoring the tire inflation status in real time. When the tire diameter increases to a preset range, inflation is stopped in time.

[0041] Please continue reading Figure 3 , a contact sensor 400 is threadedly connected to the right connecting frame 330 , and the contact sensor 400 is arranged below the corresponding laser sensor 331 ;

[0042] Working principle: When in use, the invention uses a laser sensor 331 to measure the continuously increasing diameter of the tire during the inflation process to calculate the circumference of the tire due to inflation, thereby judging the degree of inflation and monitoring the tire inflation condition in real time. When the tire diameter increases to a preset range, inflation is stopped in time, and the motor 310 drives the threaded rod 311 to rotate in the connecting groove 210, so that the threaded sleeve 320 performs a threaded feeding action along the outside of the threaded rod 311, thereby driving the position of the laser sensor 331 to change, and adjusting the height of the laser sensor 331 to adapt to the measurement of tires with different wheel diameters.

[0043] Although the present invention has been described above with reference to embodiments, various modifications may be made thereto and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as there are no structural conflicts, the various features of the embodiments disclosed herein may be combined with each other in any manner, and the omission of an exhaustive description of such combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
