[0002] A flat knitting machine, short for a knitting flat knitting machine, belongs to a kind of knitting machine, generally referring to a horizontal knitting machine, that is, a machine that uses a horizontal knitting needle bed for knitting.

[0003] When the applicant applied for the present invention, after retrieval, it was found that a Chinese patent disclosed a "yarn feeding device for a computerized knitting flat knitting machine" with an application number of "202020870121.2". This patent mainly fixes a vertical rod at both ends of the upper surface of the flat knitting machine body. An installation plate is slidably connected to the two groups of vertical rods. A number of placement rods are fixedly connected to one side wall of the installation plate. A guide ring is fixedly connected to one end of the placement rod. A driving mechanism for driving the installation plate to move up and down is provided on the upper surface of the flat knitting machine body. The yarn roller is placed on the upper surface of the flat knitting machine body. The yarn comes out of the yarn roller, passes through the guide ring and then enters the flat knitting machine body for knitting.

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Refer to Figures 1-6 , the upper thread device of a knitting flat knitting machine for textiles provided by the present utility model includes a machine body 1, a lifting mechanism 2, a power mechanism and a lowering mechanism 3 are arranged at the upper end of the machine body 1. The power mechanism is used to provide power for the lifting mechanism 2, and a connecting component 4 and a guide ring 5 are arranged at the front end of the lowering mechanism 3.

[0029] Specifically, when in use, when it is necessary to thread the yarn through multiple guide rings 5, the power mechanism provides power to the lifting mechanism 2. Then, under the action of the lifting mechanism 2, the heights of all the guide rings 5 can be reduced simultaneously, which facilitates threading the yarn through all the guide rings 5 at the same time. When it is necessary to thread the yarn through a single guide ring 5, the lowering mechanism 3 corresponding to the guide ring 5 is used to lower the height of the guide ring 5, which facilitates the operator to thread the yarn through the guide ring 5, thereby improving work efficiency. When it is necessary to replace the guide ring 5, the connection assembly 4 facilitates the replacement of the guide ring 5.

[0030] The lifting mechanism 2 includes a lead screw 201, support columns 202, a threaded barrel 203, a connecting rod 204, and a sliding barrel 205. Support columns 202 are fixedly connected to both sides of the upper end of the machine body 1, and the circumferential surface of the support columns 202 is slidably connected to the sliding barrel 205. A lead screw 201 is rotatably connected to the upper end of the machine body 1, and the circumferential surface of the lead screw 201 is threadedly connected to the threaded barrel 203. A connecting rod 204 is fixedly connected between the threaded barrel 203 and the sliding barrel 205. During operation, the lead screw 201 rotates. At this time, with the cooperation of the threaded barrel 203, the connecting rod 204 can be driven to move, and then the sliding barrel 205 can be driven to move on the support columns 202, which facilitates changing the height of the guide ring 5.

[0031] The power mechanism includes a bearing seat 6, a rotating shaft 7, a handle 8, a first bevel gear 9, and a second bevel gear 10. The bearing seat 6 is fixedly connected to the upper end of the machine body 1, and the rotating shaft 7 is rotatably connected inside the bearing seat 6. The first bevel gear 9 is fixedly connected to the front end of the rotating shaft 7. The first bevel gear 9 meshes with the second bevel gear 10, and the second bevel gear 10 is fixedly connected to the lead screw 201. The handle 8 is fixedly connected to the rear end of the rotating shaft 7. During operation, the handle 8 is rotated to drive the rotating shaft 7 to rotate. At this time, with the cooperation of the first bevel gear 9 and the second bevel gear 10, the lead screw 201 can be driven to rotate.

[0032] The lowering mechanism 3 includes a limit seat 301, a push rod 302, a rotating rod 303, a rotating cylinder 304, a torsion spring 305, a chute 306 and a slide rod 307. The upper end of the machine body 1 is fixedly connected with the limit seat 301. The push rod 302 is slidably connected inside the limit seat 301. There are multiple push rods 302, which correspond to the guide rings 5 one by one. The circumferential surface of the connecting rod 204 is rotatably connected with the rotating cylinder 304. The torsion spring 305 is fixedly connected inside the rotating cylinder 304. One end of the torsion spring 305 away from the rotating cylinder 304 is fixedly connected with the connecting rod 204; the rear end of the rotating cylinder 304 is fixedly connected with the rotating rod 303. A chute 306 is opened on the side end surface of the rotating rod 303. The slide rod 307 is slidably connected inside the chute 306. The slide rod 307 is fixedly connected with the push rod 302. During operation, by pushing the push rod 302, at this time, with the cooperation of the slide rod 307 and the chute 306, the rotating rod 303 can be driven to rotate, and then the rotating cylinder 304 can be driven to rotate. Under the action of the rotating cylinder 304, the guide ring 5 can be driven to rotate downward, so that the height of the guide ring 5 can be reduced, which is beneficial for workers to thread the yarn inside the guide ring 5; at the same time, the rotation of the rotating cylinder 304 also twists the torsion spring 305. Under the action of the torsion spring 305, it is convenient for the rotating cylinder 304 to reset.

[0033] The rotating rod 303 is in an L shape. A ball 11 is movably connected inside the lower end of the rotating rod 303. During operation, by arranging the ball 11, the friction between the rotating rod 303 and the machine body 1 can be reduced under the action of the ball 11, which is beneficial for the movement of the rotating rod 303.

[0034] The connecting component 4 includes a socket cylinder 401, a socket rod 402 and a locking screw 403. The front end of the rotating cylinder 304 is fixedly connected with the socket cylinder 401. The socket rod 402 is slidably connected inside the socket cylinder 401. The front end of the socket rod 402 is fixedly connected with the guide ring 5; the locking screw 403 is threadedly connected inside the socket cylinder 401. During operation, when the guide ring 5 needs to be replaced, the locking screw 403 is loosened. At this time, it is convenient to take out the socket rod 402 from the inside of the socket cylinder 401, so that it is convenient for workers to replace the guide ring 5.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
