[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-7This utility model provides a technical solution: a reel jaw structure that is easy to assemble and disassemble, including a hollow spindle 8. Several bow-shaped blocks and a clamping block are evenly arranged around the periphery of the hollow spindle 8. The bow-shaped blocks, clamping block, hollow spindle 8, and corresponding corner blocks mounted on it form a cylinder capable of winding strip material. The jaw includes an upper clamping block 1 and a lower clamping block 7. A jaw is provided between the upper clamping block 1 and the lower clamping block 7 for biting and clamping the end of the strip material. A jaw strip 6 is provided inside the jaw for gripping the end of the strip material. A mounting shaft is provided on the lower side between the upper clamping block 1 and the lower clamping block 7. A mounting groove corresponding to the mounting shaft is opened on the side surface of the hollow spindle 8. The upper clamping block 1, the lower clamping block 7, and their accessories can be assembled together onto the hollow spindle 8 using a disassembly and assembly tool 9. The cross-section of the disassembly and assembly tool 9 is an arc shape corresponding to the mounting shaft. The inner diameter of the disassembly and assembly tool 9 is slightly larger than or equal to the outer diameter of the mounting shaft. The center of the disassembly and assembly tool 9 coincides with the rotation center of the upper and lower clamps.

[0020] By installing the clamp blocks and their accessories onto the hollow spindle 8 using the disassembly and assembly tool 9, the difficulty of disassembling and assembling the reel jaws can be greatly reduced, the time can be shortened, the labor intensity can be reduced, the one-time production cost and use and maintenance cost of the enterprise can be further reduced, and the work efficiency can be improved.

[0021] In a preferred embodiment, 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 block 7, 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 the 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, adaptive clamping force can be achieved, preventing strip slippage. Simultaneously, the springs self-compensate when the jaws wear, ensuring a tight grip on the strip.

[0022] Furthermore, the upper jaw spring 2 and the lower jaw spring 5 are 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 respectively to maintain coaxiality.

[0023] The disassembly / assembly tool 9 should have sufficient strength to overcome the combined force generated by the springs in the upper and lower jaws. The length of the disassembly / assembly tool 9 should be at least 100mm shorter than the length of the mounting shaft.

[0024] The disassembly and assembly process of this utility model is as follows:

[0025] First, assemble the jaw bar 6 onto the lower jaw block 7.

[0026] 2. Assemble the upper jaw block 1 and the lower jaw block 7 onto the disassembly and assembly tool 9, ensuring that the center of rotation of the jaws coincides with the center of the disassembly and assembly tool 9, that is, put the center of rotation of the jaws into the groove of the disassembly and assembly tool 9; the difference between the end face of the jaw drive side and the end face of the disassembly and assembly tool 9 is about 100mm, preferably 100-200mm.

[0027] 3. Reassemble 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 follows: Figure 5 ;

[0028] IV. Hoist and assemble the entire assembly onto the hollow spindle 8, ensuring that the jaw drive side enters the hollow spindle 8 first. Then, slowly slide the jaws into the hollow spindle 8. At this time, slowly remove the operating side face of the disassembly and assembly tool 9 from the operating side face of the jaws until the jaws are fully assembled into the hollow spindle 8. Figure 6 , Figure 7 .

[0029] This structure is designed with a simple principle and is easy to assemble and disassemble. It can meet the usage requirements for reel disassembly and maintenance, ensure the convenience and reliability of reel disassembly and assembly, further reduce the labor intensity of maintenance personnel, further save labor costs and enterprise maintenance costs, and improve production efficiency at the same time.

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