The signboard is usually fixed on the base material by a hot press. The base of the hot press is provided with a limiting mechanism for limiting the placement position of the base material on the base. After placing the base material with a label on the base, the base material is moved to make the two sides of the base material close to the limiting mechanism, so as to ensure that the fixed position of the signboard on the base material does not deviate. However, for the arc-shaped structure of the base material, only the two sides of the base material contact with the limiting mechanism, which cannot well position the arc-shaped structure of the base material, and the label placement position may deviate during the processing.
