Filling device for solid tires

Abstract

The invention relates to a filling device for solid tires. The filling device for the solid tires comprises a tire clamping tool, a tire rotator, a foaming filler injection mechanical arm system, a foaming material generation system and a control system which are arranged in sequence, the tire clamping tool comprises a first base, a swing rod support assembly which can be rotationally arranged onthe first base and a wheel shaft fixing claw assembly which can be movably arranged on the swing rod support assembly, the tire rotator comprises a second base, a driving assembly which is arranged onthe second base and a friction wheel assembly which is arranged on the second base, and the foaming filler injection mechanical arm system comprises a third base and a mechanical arm assembly which can be movably arranged on the third base. Compared with the prior art, through the filling device for the solid tires, environment-friendly recycling of the tires which leak air but are in a good abrasion state or is used for a long time is achieved, and the machining and production requirements of families or street storefronts can be met.

Description

technical field [0001] The invention relates to the technical field of tires, in particular to a solid tire filling device. Background technique [0002] Every year, a large number of tires due to air leakage or long-term use are discarded. The accumulation of these tires takes up a large amount of land and causes a lot of environmental problems. How to effectively deal with the environmental pressure brought by these waste tires is the status quo that we have to face today. Research shows that only recycling is the only way to solve the problem of waste tires' post-processing, and its related research has become a hot spot. [0003] In harsh conditions, solid tires are the preferred tires for related vehicles. The carcass of solid tires is generally made of rubber or polyurethane, but rubber solid tires have disadvantages such as short service life, poor wear resistance and tear resistance. The polyurethane solid tire overcomes the shortcomings of the rubber solid tire and...

AI Technical Summary

Problems solved by technology

The carcass of polyurethane solid tires is generally poured into the mold by polyurethane foaming machine, and then it can be cast into shape. Specifically, the mold is opened in advance, the foam material is injected into the mold cavity, and the mold is closed and fastened after the injection is completed. , the preparation process is simple, but due to the rapid foaming of polyurethane, the mold must be closed before polyurethane foaming, time is tight, and it often occurs that the mold closing is too slow and a large amount of foaming material overflows the mold. Not high, and the current common solid tire (filled) injection molding process often uses special metal molds, resulting in the need to design and produce molds of different specifications during the application process
