[0027] Furthermore, a support plate 37 is provided on the outer wall of the shell 31 , and the support plate 37 is detachably connected to the yarn feeding frame 1 . The yarn feeding frame 1 is provided with a second telescopic component 11 , and the free end of the second telescopic component 11 abuts against the lower side of the support plate 37 .

[0028] Specific application examples of the utility model:

[0029] The yarn feeding roller 2 is arranged in the protective component 3 and fixed on the yarn feeding frame 1. The yarn feeding roller 2 is protected by the protective component 3. The protective component 3 is detachably connected to the yarn feeding frame 1 through the support plate 37 arranged on the side wall. The detachable connection can be fixed by bolts and fixed on the yarn feeding frame 1, which is convenient for replacing the protective component 3 and the yarn feeding roller 2. The second telescopic component 11 can be made of an electric telescopic rod. The free end of the second telescopic component 11 is mutually abutted and connected with the support plate 37, which is conducive to lifting the protective component 3 out of the yarn feeding frame 1 and replacing the protective component 3.

[0030] In the protective component 3, a cover plate 32 is provided on the upper side of the slot 33 of the yarn feeding roller 2 placed in the shell 31, which is used to control the closing of the slot 33. The cover plate 32 slides along the first guide rail 34 on the inner wall of the shell 31 to control the switch of the protective component 3. The first elastic member 35 can be made of a material with elastic deformation, such as a rubber rope. The first elastic member 35 is arranged in the first guide rail 34, and its two ends are respectively connected to the cover plate 32 and the end wall of the first guide rail 34. The elastic restoring force of the first elastic member 35 drives the cover plate 32 to slide toward the first guide rail 34 close to the bottom of the shell 31, so that the protective component 3 is in an open state, which is convenient for moving the yarn feeding roller 2 in. Two groups of clamping components 5 are provided on the inner wall of the first guide rail 34, and a slide bar 36 matching the clamping component 5 is provided on the cover plate 32. The slide bar 36 matches the clamping component 5, and the fixed cover plate 32 is located in the first guide rail 34. One group of snap-in assemblies 5 is arranged near the end of the first guide rail 34. When the slide bar 36 matches with the group of snap-in assemblies 5, the cover plate 32 completely covers the slot 33 of the housing 31. Another group is spaced apart from the end wall of the first guide rail 34. When the slide bar 36 matches with the group of snap-in assemblies 5, the cover plate 32 covers part of the slot 33, and the yarn can extend out of the protective assembly 3 through the remaining uncovered slot of the slot 33, thereby protecting the yarn feeding roller 2 during the threading process. The second elastic member 53 can be made of a spring. The second elastic member 53 pushes the card block 51 from the groove 52 into the first guide rail 34 to be snap-fitted with the slide bar 36. When the slide bar 36 needs to pass, the card block 51 can be moved into the groove 52. A limit rod 54 that is slidably plugged with the card block 51 is provided in the groove 52 to support and limit the movement of the card block 51. The inner wall of the first guide rail 34 on the side away from the groove 52 may also be provided with a notch that abuts and matches with the block 51 to support the side of the block 51 away from the groove 52 .

[0031] A guide wheel 42 is provided on the yarn feeding roller 2 near the exit of the housing 31. The yarn on the yarn feeding roller 2 changes its direction through the guide wheel 42 and then extends out of the protective assembly 3. This is beneficial for preventing the yarn from scraping against the corners of the side wall of the protective assembly 3 when moving out of the protective assembly 3. The guide wheel 42 is slidably arranged on the cross plate 4 through the moving block 41, so that the guide wheel 42 can adjust its position laterally. The connecting block 43 arranged at the end of the cross plate 4 is located in the second guide rail 44 and moves to adjust the longitudinal position of the guide wheel 42. The first telescopic assembly 45 can be made of an electric telescopic rod. The first telescopic assembly 45 is used to drive the connecting block 43 to move along the second guide rail 44.
