Advantageous effects
The utility model discloses be provided with the external conical surface of two places on the external conical surface of version conical head, these external conical surfaces of two places be with the working face of the version hole contact of version roller, can use with the version roller cooperation in different diameter version holes, and its version hole diameter of version roller when the difference is different, need not to change the version conical head on the gravure press again, has saved time and labour for the printing operation. Meanwhile, by optimizing the relative position of the inner conical surface and the outer conical surface, under the condition that the width of the outer conical surface is doubled compared with the width of the outer conical surface of the existing plate conical head, the total length of the plate conical head is not lengthened, and the basic parameters for installing the widest plate roller of the original gravure press are not influenced.

Detailed Description
The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.
The plate cone head shown in fig. 1-3 comprises a plate cone head body 1, wherein the plate cone head body 1 is a rotator structure.
The outer conical surface of the plate cone head body 1 is provided with a first outer conical surface 3 and a second outer conical surface 2 from the top 4 to the bottom 8, the first outer conical surface 3 and the second outer conical surface 2 are respectively provided with a key groove, and the key width of 10mm is the best. The diameter of the first outer conical surface 3 is smaller than that of the second outer conical surface 2, and the distance between the second outer conical surface 2 and the first outer conical surface 3 is close, so that the conical surfaces of the second outer conical surface 2 and the first outer conical surface 3 cannot be connected together without steps, and a step structure 7 is formed between the second outer conical surface 2 and the first outer conical surface 3. The presence of the step formation 7 shortens the distance of the second external tapered surface 2 from the first external tapered surface 3 to enable installation of a wider printing roll. The maximum outer diameter D of the maximum diameter position of the second outer conical surface 2 is less than or equal to 105mm, the minimum outer diameter of the minimum diameter position of the second outer conical surface 2 is more than 80mm, and the conical surface width of the second outer conical surface 2 is optimal when the conical surface width is 30 mm. The maximum outer diameter of the maximum diameter position of the first outer conical surface 3 is less than or equal to 80mm, the minimum outer diameter d of the minimum diameter position of the first outer conical surface 3 is more than or equal to 60mm, and the optimal conical surface width of the first outer conical surface 3 is 48 mm. Independent key grooves are formed in the second outer conical surface 2 and the first outer conical surface 3, and the width of each key groove is 10mm, so that the key grooves are used for installing keys for fixing the plate roller.
The medial surface of version conical head body 1 sets up interior conical surface 5 and installation fixed orifices 6 to 4 directions in top from bottom 8, is equipped with the keyway on the interior conical surface 5, and the width of keyway uses 14mm wide as the best for the key that the fixed version conical head of installation was used, and the 5 degree of depth of interior conical surface uses 85mm as the best.
