[0024] A T-shaped protrusion 12 is provided on the inner side of the supporting block 10, and a T-shaped groove 13 adapted to the T-shaped protrusion 12 is provided on the fixing seat 9. The supporting block 10 is fixed to the fixing seat 9 by bolts, so that the supporting block 10 is conveniently fixed to the fixing seat 9. The T-shaped protrusion 12 and the T-shaped groove 13 facilitate the embedded installation of the supporting block 10 on the fixing seat 9.

[0025] An embedding groove 14 is cut around the edge of one end of the rotating shaft 3 away from the connecting ear block 4, and an embedding block 15 is provided on the contact surface between the embedding head 11 and the rotating shaft 3. The embedding groove 14 and the embedding block 15 are adapted to each other.

[0026] The drying cylinder body 1 includes a cylinder body 20 and a cylinder cover 21 arranged at both ends of the cylinder body 20. A slot 22 is centrally provided on the outer surface of the cylinder cover 21. The cylinder body 20 is convenient for baking paper, and the cylinder cover 21 is convenient for sealing both ends of the cylinder body 20. The slot 22 is convenient for inserting the detachable shaft head 2 into the cylinder cover 21.

[0027] A first slot hole 16 is provided on one side of the fixing seat 9, which passes through the connecting ear block 4 and reaches the cylinder cover 21. A threaded groove 17 is provided in the first slot hole 16 in the outer wall of the drying cylinder body 1. The threaded groove 17 and the screw rod 7 are adapted to each other.

[0029] The outer surface of the cylinder body 20 is set to be smooth, which is convenient for ensuring the smoothness of the paper when baking. The diameter of the interference fit shaft 5 is slightly larger than the diameter of the slot 22, which makes it convenient for the detachable shaft head 2 to be tightly inserted into the cylinder cover 21 at both ends of the drying cylinder body 1.

[0030] The detachable shaft head 2 is inserted into the slot 22 by the interference fit plug shaft 5 and is inserted and installed. The connecting ear block 4 can be fixed on the cylinder head 21 with the assistance of bolts, so as to facilitate re-fixing the detachable shaft head 2 and the cylinder head 21.

[0031] like Figure 1-Figure 4As shown, the principle of the easily disassembled drying cylinder shaft head provided in this embodiment is as follows: when using the device, the bolts fixed on the connecting ear block 4 and the cylinder cover 21 should be removed first, and then the fixing seat 9 in the disassembly flange block 6 should be sleeved on the rotating shaft 3 on the detachable shaft head 2, and then the support block 10 should be inserted and installed on the fixing seat 9. At this time, it is necessary to ensure that the card head 11 is completely and tightly engaged with the surface of the rotating shaft 3, and then the support block 10 is fixed to the fixing seat 9 by bolts, and then the screw rod 7 is passed through the fixing seat 9 through the first slot 16, and at the same time, the hollow jack 8 is placed on the fixing seat. The screw rod 7 is inserted between the seat 9 and the connecting ear block 4, and then the screw rod 7 passes through the hollow jack 8, and then the gasket 19 is put on the screw rod 7 and fits tightly on the output end of the hollow jack 8, and then the fixed limit nut 18 is put on the screw rod 7, and then the screw rod 7 is screwed and fixed on the first slot 16 on the cylinder head 21. At this time, the detachable shaft head 2 can be ejected from the cylinder head 21 by extending the hollow jack 8. During the ejection process, it is necessary to ensure that the screw rod 7 has enough length, and at the same time, the position of the fixed limit nut 18 should be properly adjusted to ensure that the detachable shaft head 2 can be completely ejected;

[0032] After the detachable shaft head 2 is pushed out, the old detachable shaft head 2 and the disassembly flange block 6 can be taken out from the screw rod 7, and then the hollow jack 8, the gasket 19 and the fixed limit nut 18 can be taken out from the screw rod 7, and then the new detachable shaft head 2 can be sleeved on the screw rod 7, and then the hollow jack 8 and the gasket 19 can be sleeved on the screw rod 7 in sequence, and at the same time, the fixed limit nut 18 can be screwed and fixedly sleeved on the screw rod 7. At this time, the detachable shaft head 2 can be squeezed and pushed into the cylinder head 21 by the extension of the hollow jack 8, and finally the fixed limit nut 18, the gasket 19 and the hollow jack 8 on the screw rod 7 can be taken out from the screw rod 7 in sequence, and then the screw rod 7 can be screwed and taken out from the first slot 16 on the cylinder head 21, and then the detachable shaft head 2 can be further fastened to the cylinder head 21 by bolts.

[0033] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0034] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.
