Detailed Description

The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

Example (b): as shown in fig. 1, 2, 3 and fig. 4, a novel efficient winding device for warp knitting machine, including bracket mounting plate 11, and both ends are inserted winding roller 12 on the bracket mounting plate 11, still include the follow mounting groove 1 that winding roller 12 anchor ring inwards seted up, one end articulates in mounting groove 1 one side position department and through the rotatory mode of opening in order to be used for separating the rotor plate unit 2 of coil, set up and be used for the closing cap on the mounting groove 1, attached rotatory opening the tectorial membrane unit 3 on rotor plate unit 2 surface, and set up and be in on the mounting groove 1 bottom surface and through the spacing mode of hoop in order to be used for the block fixed rotatory opening the salient post unit 4 of rotor plate unit 2.

In this embodiment, when the winding roller 12 winds a kind of yarn, the rotating plate unit 2 rotates and is folded into the installation groove 1, the protruding column unit 4 is closed to limit, and the film covering unit 3 covers and protects the whole installation groove 1, so as to prevent dust and lint from entering the installation groove 1, prevent the yarn from hooking and breaking at the fine structure in the installation groove 1, and ensure the integrity of the use effect.

When the winding device needs to wind two or more kinds of yarns simultaneously or successively, the rotating plate unit 2 is rotated and opened to be perpendicular to the winding roller 12, at the moment, the protruding column unit 4 firstly triggers a limiting effect on the rotating plate unit 2 to ensure that the rotating plate unit 2 cannot be accidentally rotated and folded, and finally, one side edge of the film covering unit 3 which is obliquely pulled up and is in a folded angle shape is attached to the side surface of the rear end of the rotating plate unit 2 in the rotating direction, at the moment, the film covering unit 3 is approximately in a shape of a Chinese character ji, so that the phenomenon that the normal winding of the yarns is influenced by the oblique pulling up of the film covering unit 3 is avoided, and the rotating plate unit 2 is kept in a rotation opening state from the beginning to the completion of the whole paying-.

And finally, after the corresponding coil on the winding roller 12 is paid off, the protruding column unit 4 is firstly pulled to withdraw, the rotating plate unit 2 loses the limiting effect and then rotates to fold, so that the next reuse is facilitated, and the problems that different coils are overlapped with each other during winding and the subsequent coil on the inner side is not easy to pay off can be solved.

The long axial direction of the mounting groove 1 and the film coating unit 3 is the same as the axial direction of the winding roller 12, the rotating plate unit 2 comprises a fixing shaft 201 arranged at one side position in the mounting groove 1, a rotating plate 202 for separating coils during winding, and a sleeving hole 203 arranged at one side position on the rotating plate 202, and the film coating unit 3 comprises an elastic film 301, two side edges of which are respectively bonded and fixed on the mounting groove 1, the elastic film is close to the fixing shaft 201 and far away from the positions at two sides of the fixing shaft 201. The film covering unit 3 further includes an on-film magnet piece 302 adhesively disposed on the outer side surface of the elastic film 301, and a first on-plate magnet piece 303 adhesively disposed on the lower surface of the rotating plate 202 at a position close to the fixed shaft 201 and configured to attach the elastic film 301 to the rotating plate 202 rotated open by magnetically attracting the on-film magnet piece 302. The film covering unit 3 further includes a second upper plate magnet piece 304 which is adhesively disposed on the upper surface of the rotating plate 202 at a position away from the fixed shaft 201 and which is used to attach the elastic film 301 to the rotating plate 202 which is rotated and closed by magnetically attracting the upper plate magnet piece 302 to each other.

In the present embodiment, the method of using the rotating plate unit 2 to separate the coils and the advantages thereof are as follows.

Firstly, the rotating plate 202 rotates around the fixed shaft 201 to open and close so as to block coils between adjacent coils during winding, the elastic film 301 is made of an existing elastic plastic film and is used for covering details in the mounting groove 1 and attached to the surface of the rotating plate 202 which is opened by rotation, and the effect of preventing yarns from being hooked and broken is achieved.

Secondly, when the rotating plate 202 is rotated to open for separate winding, the elastic membrane 301 is supported by the rotating plate 202 to have a hypotenuse and a square similar to a right triangle, and at this time, a magnetic attraction effect between the magnet sheet 302 on the membrane and the magnet sheet 303 on the first plate is required to stretch the hypotenuse region of the elastic membrane 301 inwards to be flush with the mounting groove 1 and attached to the rotating plate 202, that is, the elastic membrane 301 generally forms a shape like a Chinese character 'ji', so that the normal winding and looping operation of the yarns are not affected.

Third, when the rotating plate 202 is rotated and folded, the elastic film 301 limits the position of the rotating plate in the mounting groove 1 to the outside so that the rotating plate cannot be opened accidentally, but the rotating plate may be shaken, so that a magnetic attraction action between the magnet pieces 302 on the film and the magnet pieces 304 on the second plate is required to stably fix the rotating plate 202, thereby preventing the above-mentioned undesirable shaking.

Fourthly, when the rotating plate 202 needs to be rotated and opened, the rotating plate 202 and the elastic film 301 can be pinched by hands and lifted together, and after the rotating plate 202 partially rotates and slides out of the mounting groove 1, the rotating plate 202 can be supported and pushed from the rear end side in the rotating direction of the rotating plate 202 and continuously rotated and opened upwards until the rotating plate is rotated to be perpendicular to the winding roller 12.

The rotating plate unit 2 further includes protruding plates 204 respectively disposed on upper and lower surfaces of the rotating plate 202 and elastically clamped on the rotating plate 202 opened by rotation by the elastic film 301 to fix the coil ends.

In this embodiment, after the yarn is wound, the outer end of the yarn can pass through the clamping effect between the elastic film 301 and the protruding plate 204 to ensure that the movable end of the yarn is not disturbed, the coil is not easy to loosen, and the outer end of the yarn can be properly pulled and tightened when being clamped to ensure the fixing effect.

The protruding column unit 4 includes a fixed cylinder 401 disposed on the inner bottom surface of the mounting groove 1, a limit column 402 having a lower end inserted into the fixed cylinder 401 and an annular surface abutting against the lower surface of the rotating plate 202 that is rotated to be opened, and a jacking spring 403 disposed in the fixed cylinder 401 and jacking up the limit column 402 by an elastic force so as to open and close a limit function of the limit column 402. The film covering unit 3 further comprises a hole opening block 305 adhered to the outer surface of the magnet piece 302 on the film, a toggle column 306 inserted into the hole opening block 305, and an elastic rope 307 pulling the toggle column 306 on the side surface of the hole opening block 305, and the protruding column unit 4 further comprises a toggle insertion groove 404 arranged on the upper end surface of the limit column 402 and used for closing the limit function of the limit column 402 by inserting the toggle column 306 downwards through the elastic film 301 and pushing the limit column 402.

In this embodiment, initially, the rotating plate 202 is pressed against the limiting post 402 when rotated and folded, the protruding post unit 4 has no limiting effect, and then after the rotating plate 202 is rotated and opened, the jacking spring 403 jacks the limiting post 402 outwards, the limiting post 402 is attached to the rotating plate 202, and at this time, the self-rigidity of the limiting post 402 is used to ensure the limiting effect on the rotating plate 202, so that the rotating plate 202 is not prone to accidentally fold after being rotated and opened, and therefore, in this process, the elastic force of the jacking spring 403 is not too large, and the material of the limiting post 402 needs to be relatively hard metal.

Secondly, if the rotating plate 202 needs to be rotated and folded, the limiting post 402 needs to be pushed inward to retract first, at this time, the rotating plate 202 rotates and folds inward while pressing the limiting post 402 to retract slowly, and finally the limiting effect of the protruding post unit 4 can be released, in the process, the toggle post 306 needs to be manually pushed downward to be inserted into the toggle insertion groove 404 to retract the limiting post 402, in the process, the rotating plate 202 rotates and folds synchronously, after the limiting effect disappears during the rotation force application, the toggle post 306 can be released, the rotating plate 202 presses back the limiting post 402, and importantly, the toggle post 306 needs certain elasticity to meet a certain bending action state when the limiting post 402 is pushed downward.

The protruding column unit 4 further includes a radial plate 405 disposed at a lower end of the annular surface of the limiting column 402 and used for limiting and fixing the inner annular surface of the fixed cylinder 401, and having an arc-shaped end, and a nut 406 having an opening at a middle portion thereof, sleeved on the limiting column 402, screwed with the outer annular surface of the fixed cylinder 401, and used for limiting and fixing the radial plate 405. The projecting pole unit 4 further includes a spring groove 407 provided on the lower end surface of the stopper pole 402 and into which the jack-up spring 403 is inserted. The upper end of the limiting column 402 is a spherical surface, and the poking insertion groove 404 is arranged in the middle of the spherical surface.

In this embodiment, the size of the slot of the toggle insertion slot 404 is larger than the diameter of the toggle post 306, so as to ensure that the toggle post 306 has a sufficient bending space when being toggled down.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various modifications can be made within the knowledge of those skilled in the art without departing from the gist of the present invention. These are non-inventive modifications, which are intended to be protected by patent laws within the scope of the claims appended hereto.
