New description: v [New technical field] This case belongs to the circular knitting machine. It is a main cloth that automatically excludes cotton wool. It is a structure that can be selected. The chaotic head of the chastity function [Prior technology] - The common circular knitting machine is the same as the multi-spot image of the M. · #辨• Various fabrics with a 丨J邑 and pattern, one cam and one #圆The bottom surface of the disc is respectively provided with 掏 and #动, and the disc is 罟 罟 掂 绿 绿 绿 绿 绿 绿 绿 绿 绿 绿 绿 绿 绿 绿 绿 绿 绿 绿 绿 绿 绿 绿 绿 绿 绿 绿 绿 绿 绿 绿 绿 绿 绿 绿 绿 绿 绿The yarn group is rotated synchronously by the rotation of the disk and the actuator. After the rotation, the β 啄 is convex to the opposite side of the wire changing device to be used, and the actuator is selected by the actuator: Check the ", the yarn group, so that the cam is connected with the clip-cut yarn group to drive a yarn, and the yarn is driven to the arbor yarn of the color-changing head for switching. The purpose of the different yarns, wherein the clamping yarn group is formed by the yarn changing plate, the movable plate and the cutting plate in sequence, and forms a closed structure. When the clip-cut yarn group is actuated by the operation of the cam, the cutting plate and the yarn-carrying plate are transferred to the & 7 ^ you are not moving, and the The yarn changing plate interlocks the movable blade to perform the hooking and the cutting operation respectively. However, since the yarn changing plate and the movable blade have mutually connected limiting holes and limiting portions, after long time use, The cotton yarn is generated by repeatedly switching the yarns, and the cotton wool is piled on the M421950 limit hole of the yarn change plate and the limit portion of the movable blade, so that the action of cutting the yarn defect is hindered and becomes unsmooth. , I to cause damage to the body' and must regularly remove the accumulated cotton wool to ensure smooth operation. The traditional closed color change head must be completely disassembled for maintenance, which is quite inconvenient and costly for maintenance personnel. It has been proposed that the new patent of the Republic of China 帛 帛 239 "Open-type color change head changer" will be placed on the movable knives and the limit holes on the change plate, and then on the movable blade and The splints are respectively provided with hollowed-out portions, and a channel design for facilitating the cleaning and accumulation of the batt is formed, and the maintenance personnel can use the passage to remove the accumulated batt without disassembling the discolored head, thereby maintaining the operation. Smoothness and long life, but after the actual test that is still not entirely perfect place and must be improved. In view of this, the creator further provides a self-cleaning function of the color-changing head structure, which is provided with a notch on one side of a movable blade, thereby reducing the chance of cotton accumulation and operating on the movable blade. At the same time, the cotton accumulated in the interior of the color changing head is automatically released, thereby maintaining the smoothness of the operation and prolonging the use of the smear. [New content] A purpose of this creation is to provide a structure with self-cleaning work-changing heads. 俾Using a new movable blade design, the splint of the eight-in-one 卩σ卩 is applied, and the internal order is activated. The accumulated batt of the batt will discharge 'according to the smoothness of the operation and the extension of 4 to reduce the chance of internal accumulation of batt; furthermore, when the movable blade is in operation, the notch can be stacked in the clip The batt between the yarn board and the cutting board is hooked out and automatically cleared by the passage to maintain the smoothness of the operation and prolong the service life thereof. In one embodiment, the 'self-cleaning function of the color-changing head structure' further includes a plurality of separators respectively disposed between the moxibustion cut yarn sets, and can surely separate the clip-cut yarn components Set 'to avoid interference between components in between. [Embodiment] In order to make your reviewer understand the content of this creation, please refer to the following description. BRIEF DESCRIPTION OF THE DRAWINGS Referring to Figures 1, 2, 3 and 4, there is shown a schematic view of an assembled view of a preferred embodiment of the preferred embodiment of the present invention, a schematic view of the mounting thereof, and a partial cross-sectional view thereof. As shown in the figure, the self-cleaning discoloration head structure 1 of the present invention is installed under the disc 21 of a circular knitting machine 20, and with a cam 22 and an actuator of the disc 21 23 is connected for switching each yarn 30 in the knitting process. The self-cleaning function of the color changing head structure 10 includes two clamping plates 11, a plurality of clamping yarn groups 12 and a plurality of control plates 13. The pair of splints 11 has a first limiting post ill, a second limiting post 112 and a plurality of hollowing portions 113, and a fixing seat 114 and a yarn feeding port 115 are disposed on the same side of the pair of clamping plates 11, and The first limiting post 111 is disposed on one side of the yarn feeding port 11 5 , and the second limiting post 11 2 of the M421950 is disposed on one side of the fixing seat 11 4 . Further, the fixing base 114 has a mortise fixing hole 1141 for locking to the circular knitting machine 20. Further, the yarn feeders 11 5 have a plurality of perforations 11 51 for sequentially inserting the yarns 30 into the perforations 1151. The plurality of tangential yarn groups 12 are sandwiched between the two slabs 11 and the at least one of the splicing yarn groups 12 has at least one partition 12 for separation. The clipping yarn set 1 2, wherein the clipping yarn sets 1 2 respectively comprise: a yarn changing plate 1 21 disposed on the inner side of one of the clamping plates 11 for threading the yarn 3 〇, and dialing The yarn 30 is moved to the yarn feeding port 11 5 , and the yarn changing plate 1 21 has a curved shape limiting hole 1 211 , and the first limiting column 111 is interposed between the clamping plates 丄j In the limiting hole l 211, one end of the yarn changing plate 1 21 has a limiting portion 1 21 2 , and at the end of the yarn changing plate 1 21 , there is a threading hole 1 21 3 and a lever. The other end portion has an actuation portion ι215. The actuation portion 1215 is coupled to the cam 22, and is driven by the cam 22 to synchronously reciprocate. A resilient member 12 22 is disposed between the pair of clamping plates 11 and One end of the elastic element 1 22 is abutted against the edge of the yarn changing plate 1 21 so that the limiting portion 1 21 2 of the yarn changing plate 1 21 is abutted against the first limiting column 11 2; Board 1 2 3 'on one side of the yarn changing plate 121, the cutting plate i 23 has an end portion having all the blade portions 1231 to cut the yarn 3'' and the cutting plate 123 does not shield the second plate 11 The movable portion 113; a movable blade ι24, is provided with an 8 ivmiy 50 channel 40, and further, when the movable blade 124 is operated, the notch portion 1243 is used to deposit the cotton wool accumulated between the clamping plate 125 and the cutting plate 123. Hook out, and achieve the purpose of maintaining the smoothness of the action and effectively extending the service life. Furthermore, since the components of the present invention are greatly reduced in area, the hollow portions 11 3 ' of the two plywoods ii are added to reduce the overall weight to achieve weight reduction, and the manufacturing time can be effectively reduced. Material cost. The above is only the preferred embodiment of the present invention and is not intended to limit the scope of the present invention, such as the shape, size, etc. of the hollow portions or the use of such components. The material or its surface coating, etc., are also in the scope of this case, so it is the general knowledge of the technical field, or the equivalent or easy change of the technology. Equivalent changes and final decorations made without departing from the spirit and scope of this creation shall be covered by the scope of this creation.
