Problems solved by technology

When there are appearance problems on the sidewall of old tires, it is generally handled by manual cleaning by operators, so the workload is heavy and the treatment effect is not obvious
[0004] If supporting equipment is used to grind the sidewall area, for the grinding devices disclosed or used in the prior art, how to accurately control the feeding distance of the grinding head and how to delineate the grinding range along the vertical area of ​​the sidewall are also important issues. It cannot be solved, so the precise grinding of sidewall parts is always an unsolved problem

Abstract

The invention discloses a tyre retreading sidewall sanding device and a sanding method thereof, provides a sidewall sander matched with overall unit sanding equipment, improves the sanding precision of a sanding head within a set sidewall range, realizes a full-automatic sanding device, and is free of manual operation of operators to finish the sidewall sanding, thereby enhancing the sanding quality of the sidewall and improving the appearance effect of the sanded sidewall. The sidewall sanding device is arranged on the top part of a sander main framework, an electric cylinder thereof is arranged on the main framework, the drive rod of the electric cylinder is connected with a carriage which is movably sleeved on an optical axis arranged vertically, the top ends of two groups of symmetrical sliding plates are respectively connected with the carriage via a hinged shaft, and the bottom end of each sliding plate is provided with a sanding wire wheel which is sleeved on the drive shaft of a motor. Based on the sidewall sanding range set manually by an operator, the electric cylinder drives the carriage to vertically move to a position to be processed and the motor drives the above sanding wire wheel to finish sanding and cleaning of the sidewall.

Description

technical field [0001] The invention relates to a sidewall grinding device applied to tire retreading manufacturing equipment and a control method for realizing precise grinding within a set sidewall area, belonging to the field of rubber machinery. Background technique [0002] Nowadays, the number of tires used by vehicles such as automobiles and airplanes is relatively large every year, which correspondingly brings a series of waste of resources and environmental pollution problems caused by the disposal of scrap tires. At present, for old tires with worn out tread patterns, grinding treatment and re-vulcanization molding are generally adopted to put them into recycling, which can save rubber materials and protect the environment to a large extent. [0003] The existing domestic tire retreading equipment has a relatively low degree of automation in its production process. The grinding machine adopted mainly grinds the tread of old tires. When there are appearance proble...
