[0026] 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.

[0027] like Figures 1-7 As shown, this utility model provides a technical solution: a material box conveying fixture for a mask machine, including a material box body 1 and connecting ears 3 that are fixedly connected at equal intervals on the chain 2 of the material box body 1. The connecting ears 3 and the chain links of the chain 2 are an integral structure. A fixing pin 4 is fixedly connected to the front of the connecting ears 3, and the fixing pin 4 and the connecting ears 3 are fixedly an integral structure.

[0028] A sleeve 5 is fixedly connected to the back of the material box body 1 and is movably sleeved on the fixing pin 4. The sleeve 5 is symmetrically arranged on the back of the material box body 1. A fixing seat 7 is fixed on the back of the material box body 1. The fixing seat 7 is a horizontally arranged long strip structure and is located in the center of the back of the material box body 1. A long screw 6 is horizontally installed through the sleeve 5 and the fixing pin 4. The long screw 6 is threadedly connected to the fixing seat 7.

[0029] The mounting base 7 has a mounting groove 12 in the center of its back side that communicates with the inner cavity 8. A support spring 9 is installed in the inner cavity 8 of the mounting base 7. Support blocks 10 are installed at both ends of the support spring 9. The long screw 6 has threads 11 on only part of the surface of the mounting base 7. The long screw 6 has a guide chamfer structure at one end of the mounting base 7 corresponding to the long screw 6. The mounting base 7 has a threaded hole 13 in the position corresponding to the long screw 6 that communicates with the inner cavity 8. The end of the threaded hole 13 away from the inner cavity 8 has a guide groove 14. The support block 10 is supported on the end of the long screw 6.

[0030] Working principle:

[0031] The sleeve 5 on the back of the material box body 1 is fitted onto the fixing pin 4 on the connecting ear 3. The long screw 6 passes horizontally through the sleeve 5 and the connecting ear 3 to complete the fixation, which is convenient for disassembly and assembly. A long section of the long screw 6 is threadedly connected to the fixing seat 7, which is not easy to loosen. At the same time, the support spring 9 inside the fixing seat 7 supports the long screw 6 with elastic force, increasing the friction between the thread 11 on the surface of the long screw 6 and the threaded hole 13 of the fixing seat 7, realizing thread self-locking, further improving the installation firmness, and achieving the effect of convenient installation, inspection and maintenance and not easy to loosen.
