Description

Technical Field

[0001] The present invention relates to the technical field of tire anti-skid spike fixing equipment, in particular to a semi-automatic tire anti-skid spike fixing equipment. Background Art

[0002] In winter, in areas with snowy roads, the wheels need to be more skid-resistant to ensure adequate road adhesion and reduce the risk of accidents. Studded tires are designed for this purpose. These tires have numerous special metal studs embedded in the tire casing. These studs dig into the road surface on icy roads, preventing skidding. Installing the studs requires a tire-setting machine.

[0003] After searching, it was found that most of the existing anti-skid stud nailing devices are semi-automatic nailing devices, which require holding the tire body and placing it on a bracket, and then moving the tire body along with the intermittent nailing of the nailing mechanism to achieve the purpose of uniform nailing. This method consumes a lot of labor; there are also some automatic nailing devices, but this type of nailing device only pushes the tire body into the nailing position in a horizontal manner when loading, and as the tire rotates, it will cause friction on a series of clamping components. Therefore, we propose a new type of automatic anti-skid stud nailing equipment. Summary of the Invention
