[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] See also Figure 1-7The present invention provides a technical solution: a reel jaw structure and disassembly tool that are easy to disassemble and assemble, comprising a hollow main shaft 8, wherein a plurality of bow blocks and a clamp block are evenly arranged on the circumference of the hollow main shaft 8. The bow blocks, the clamp block and the hollow main shaft 8 and the corresponding corner blocks installed thereon form a cylinder capable of winding the strip. The jaws comprise an upper clamp block 1 and a lower clamp block 7. A jaw is provided between the upper clamp block 1 and the lower clamp block 7 for biting into and clamping the end of the strip. A jaw strip 6 is provided inside the jaws for biting the end of the strip. A mounting shaft is provided on the lower side between the upper clamp block 1 and the lower clamp block 7. A mounting groove corresponding to the mounting shaft is provided on the side surface of the hollow main shaft 8. The upper clamp block 1 and the lower clamp block 7 and their accessories can be assembled on the hollow main shaft 8 together through the disassembly tool 9. The cross section of the disassembly tool 9 is an arc shape corresponding to the installation shaft. The inner diameter of the disassembly tool 9 is slightly larger than the outer diameter of the installation shaft or equal to the diameter of the installation shaft. The center of the disassembly tool 9 coincides with the rotation center of the upper and lower clamps.

[0016] By installing the pair of clamps and their accessories of the disassembly and assembly tool 9 onto the hollow main shaft 8, the difficulty of disassembling the reel jaws can be greatly reduced, the time can be shortened, the labor intensity can be reduced, the company's one-time production cost and use and maintenance cost can be further reduced, and work efficiency can be improved.

[0017] In a preferred technical solution, an upper jaw spring sleeve 3 is provided on the inner side of the upper jaw block 1, and an upper jaw spring 2 is provided on the inner side of the upper jaw spring sleeve 3; a lower jaw spring sleeve 4 is provided on the inner side of the lower jaw spring sleeve 4, and a lower jaw spring 5 is provided on the inner side of the lower jaw spring sleeve 4. The upper jaw spring 2 and lower jaw spring 5 upgrade the traditional rigid jaws to adaptive elastic jaws. Through triple coordination with the jaw bar 6 and the mounting shaft, the clamping force can be adaptive, preventing the strip from slipping. At the same time, the spring can self-compensate when the jaws wear, ensuring a tight grip on the strip.

[0018] Furthermore, the upper jaw spring 2 and the lower jaw spring 5 adopt rectangular cross-section mold springs (stiffness ≥ 8 N / mm), with a pre-compression amount Δ=2 mm, and are guided by the upper jaw spring sleeve 3 and the lower jaw spring sleeve 4 to maintain coaxiality.

[0019] The present invention also provides a disassembly tool for disassembling and assembling reel jaws, comprising a disassembly tool 9 having an arc-shaped cross-section corresponding to the mounting axis. Disassembly tool 9 is sufficiently strong to overcome the combined force generated by the upper and lower jaw attachment springs. The length of disassembly tool 9 is at least 100 mm shorter than the mounting axis, preferably 100-200 mm.

[0020] The disassembly and assembly process of the present invention is as follows: 1. Assemble the jaw strip 6 onto the lower jaw block 7 first.

[0021] 2. Assemble the upper jaw 1 and the lower jaw 7 onto the disassembly and assembly tool 9, ensuring that the rotation center of the jaws coincides with the center of the disassembly and assembly tool 9, that is, place the rotation center of the jaws into the groove of the disassembly and assembly tool 9; the end face of the jaws on the transmission side and the end face of the disassembly and assembly tool 9 are about 100 mm apart.

[0022] 3. Assemble the upper jaw spring 2, upper jaw spring sleeve 3, lower jaw spring sleeve 4, and lower jaw spring 5 onto the corresponding upper jaw block 1 and lower jaw block 7, as shown in the following figure: Figure 5 ; Fourth, hoist and assemble the above-mentioned whole together onto the hollow main shaft 8, making sure that the transmission side of the jaws enters the hollow main shaft 8 first, and then slowly slide the jaws into the hollow main shaft 8. At this time, the operating side end face of the disassembly and assembly tool 9 slowly leaves the operating side end face of the jaws until the jaws are completely assembled into the hollow main shaft 8. Figure 6 、 Figure 7 .

[0023] The structural design principle is simple and the disassembly and assembly is convenient. It can meet the use requirements of the reel disassembly and assembly maintenance, ensure the convenience and reliability of the reel disassembly and assembly, further reduce the labor intensity of maintenance personnel, further save labor costs and enterprise maintenance costs, and at the same time improve production efficiency.

Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
