[0026] Embodiment 1:

[0027] See also Figure 1-3In this embodiment, a cutting device for cotton yarn processing includes a mounting frame 1, which is characterized in that: a support arm 11 is arranged on the top of the mounting frame 1, and a winding roller 12 is rotatably connected to the support arm 11, and the winding roller 12 is used to wind up the cotton yarn; two connecting arms 13 are also arranged on the top of the mounting frame 1, and the tops of the two connecting arms 13 are rotatably connected to the conveying components 3, and the two connecting arms 13 are also provided with a slide groove 14, and the slide groove 14 is provided with a support component 2; two cutting components 4 are arranged on the mounting frame 1, and the cutting component 4 includes a mounting arm 41, and a mounting groove 42 is provided in the mounting arm 41, and a sliding connection is provided in the mounting groove 42 There is a tool holder 43, one side of the tool holder 43 is fixedly connected to a cutting blade 44, the other side of the tool holder 43 is fixedly connected to a return spring 45, the return spring 45 is fixedly connected to one side of the mounting groove 42, one side of a mounting arm 41 is rotatably connected to a second driven wheel 46, the second driven wheel 46 is fixedly connected to a transmission rod 47, the transmission rod 47 passes through the mounting arm 41 and is fixedly connected to a transmission cam 48; a transmission motor 15 is provided at the bottom of the mounting frame 1, the output shaft of the transmission motor 15 is fixedly connected to a transmission wheel 16, the transmission wheel 16 is transmission-connected to the conveying component 3, and the conveying component 3 is transmission-connected to the transmission cam 48.

[0028] As a preferred technical solution in this embodiment: in actual use, the staff can first reel up the cotton yarn to be cut on the winding roller 12, and then pass one end of the cotton yarn through the support component 2 and the conveying component 3, and make it located between the cutting blade 44 and the mounting frame 1. Then the staff can control the transmission motor 15 to drive the transmission wheel 16 and the conveying component 3 to rotate. During the rotation of the conveying component 3, the second driven wheel 46 can be driven to rotate the transmission cam 48. During the rotation of the transmission cam 48, when its protruding part contacts the knife holder 43, it can drive the knife holder 43 to slide in the mounting groove 42. During the sliding of the knife holder 43, the cutting blade 44 can be effectively driven to cut the cotton yarn.

[0029] It is worth noting that when the top of the protruding part of the cutting blade 44 contacts the blade holder 43, the cutting edge of the cutting blade 44 just contacts one side of the mounting frame 1. Furthermore, in order to avoid the cutting blade 44 from curling, the staff can set a pad on the mounting frame 1.

[0030] Embodiment 2:

[0031] See also Figure 4-5In order to achieve the effect of cutting the cotton yarn at equal intervals, the present embodiment is characterized in that: the conveying assembly 3 includes a conveying roller 31, the conveying roller 31 is rotatably connected to the two connecting arms 13, a connecting rod 32 is fixedly connected to one end of the conveying roller 31, the connecting rod 32 passes through a connecting arm 13 and is fixedly connected to a first driven wheel 33, a first transmission belt 35 is tensionedly connected between the first driven wheel 33 and the transmission wheel 16. A linkage wheel 34 is fixedly connected to the first driven wheel 33, and a second transmission belt 36 is tensionedly connected between the linkage wheel 34 and the second driven wheel 46.

[0032] In order to ensure the effect of outputting the cotton yarn, the support assembly 2 in this embodiment includes a support roller 21, and both ends of the support roller 21 are fixedly connected with sliders 22, and the sliders 22 are slidably connected to the slide groove 14. The bottoms of the two sliders 22 are fixedly connected with support springs 23, and the other ends of the support springs 23 are fixedly connected to the bottom of the slide groove 14. A plurality of anti-slip grooves are provided on the sliders 22 and the conveying roller 31.

[0033] This connection method effectively ensures that the cotton yarn can be well conveyed during use. A support spring 23 is provided at the bottom of the slider 22, so that the slider 22 and the support roller 21 can be effectively supported during use, thereby ensuring that the cotton yarn between the support roller 21 and the conveying roller 31 is always kept in contact with the cotton yarn, thereby ensuring the conveying effect of the cotton yarn. A plurality of anti-slip grooves are provided on the conveying roller 31 and the support roller 21, so that the friction between the cotton yarn and the support roller 21 can be increased during use, thereby further improving the conveying effect.

[0034] A storage frame 17 is provided on one side of the mounting frame 1, and the storage frame 17 is located below the cutting assembly 4. By providing the storage frame 17, a good collection effect can be achieved for the cotton yarn cut by the cutting assembly 4, thereby ensuring its stability during use.

[0035] As a preferred technical solution in this embodiment: in actual use, when workers pass the cotton yarn between the conveying roller 31 and the supporting roller 21, they can control the transmission motor 15 to drive the transmission wheel 16 to rotate. During the rotation of the transmission wheel 16, the first transmission belt 35 can be driven to rotate the conveying roller 31. During the rotation of the conveying roller 31, the cotton yarn can be effectively conveyed. At the same time, during the rotation of the conveying roller 31, the first driven wheel 33 can be driven to rotate the second driven wheel 46. During the rotation of the second driven wheel 46, the cotton yarn can be effectively cut.

[0036] It is worth mentioning that when the conveying roller 31 rotates one circle, the second driven wheel 46 also rotates one circle. At this time, the conveying roller 31 conveys cotton yarn of its circumference, and the second driven wheel 46 just drives the cutting blade 44 to cut the cotton yarn once, thereby achieving the effect of cutting the cotton yarn of the circumference of the conveying roller 31 every time the second driven wheel 46 rotates one circle.

[0037] The working principle of the above embodiment is:

[0038] 1. In actual use, the staff can first reel up the cotton yarn to be cut on the reel-up roller 12, and then pass the cotton yarn between the conveying roller 31 and the supporting roller 21. At this time, the staff can control the transmission motor 15 to drive the transmission wheel 16 to rotate. During the rotation of the transmission wheel 16, the first transmission belt 35 can be driven to rotate the conveying roller 31. During the rotation of the conveying roller 31, the cotton yarn can be effectively conveyed. At the same time, during the rotation of the conveying roller 31, the first driven wheel 33 can be driven to rotate the second driven wheel 46.

[0039] 2. When the linkage wheel 34 drives the second driven wheel 46 to make the transmission cam 48 rotate, when the protruding part of the transmission cam 48 contacts the knife holder 43, it can drive the knife holder 43 to slide in the installation slot 42, and when the knife holder 43 slides, it can effectively drive the cutting blade 44 to cut the cotton yarn. When the conveying roller 31 rotates one circle, the second driven wheel 46 also rotates one circle. At this time, the conveying roller 31 conveys the cotton yarn of its circumference, and the second driven wheel 46 just drives the cutting blade 44 to cut the cotton yarn once, so that the cutting blade 44 can cut the cotton yarn of the circumference of the conveying roller 31 every time the second driven wheel 46 rotates one circle.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
