Detailed implementation manners

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Please refer to Figure 1-7, the present invention provides a technical solution: a multifunctional polyester-cotton yarn automatic winding machine. Above the base 1, a lifting protective cover 2 is provided, and a circulating filtration mechanism 3 is installed on the top of the lifting protective cover 2. Below the lifting protective cover 2 on the top of the base 1, an installation box 4 is provided, and a driving motor 401 is installed on the outside of the installation box 4.

[0036] Specifically, the lifting protective cover 2 includes a protective cover 201. On one side of the protective cover 201, an operation door matching it can be installed, which is convenient for operating the equipment inside the protective cover 201 when the protective cover 201 contacts the base 1 later. On both sides of the protective cover 201, driving blocks 202 are provided. The driving blocks 202 are slidably connected to the inside of the vertical grooves 203, and the driving blocks 202 are connected to a second lead screw mechanism 204 rotatably arranged inside the vertical grooves 203. One end of the second lead screw mechanism 204 is connected to a motor 205.

[0037] In a further embodiment, a through groove is opened on one side of the protective cover 201, and a wire guide cylinder 206 is fixedly installed inside the through groove.

[0038] When it is necessary to adjust the height of the protective cover 201, the motor 205 is turned on. Under the action of the motor 205, the second lead screw mechanism 204 rotates, thereby driving the driving blocks 202 and the protective cover 201 to move, so that the height of the protective cover 201 changes.

[0039] Specifically, the circulating filtration mechanism 3 includes an air inlet fan 301. The air inlet end of the air inlet fan 301 is connected to the inside of the protective cover 201 through a first connecting pipe 302. The air outlet end of the air inlet fan 301 is connected to one end of a purification box 303 through a second connecting pipe. The other end of the purification box 303 is connected to an air outlet fan 304 through a third connecting pipe. The air outlet end of the air outlet fan 304 is connected to the inside of the protective cover 201 through a fourth connecting pipe 305.

[0040] Further explanation, filtration mechanisms are provided inside both the air inlet fan 301 and the air outlet fan 304 to reduce the impact of dust-containing gas on the fans.

[0041] Specifically, a filter screen 3031 is installed inside the purification box 303, and a water curtain filtering mechanism 7 is arranged on one side of the filter screen 3031. The water curtain filtering mechanism 7 includes a water storage tank 701, and the water storage tank 701 is located at the bottom of the purification box 303. An impurity filter screen can be arranged inside the water storage tank 701 for filtering impurities in water in the later stage. The inside of the water storage tank 701 is connected to a delivery water pump 702, and the delivery water pump 702 is connected to a water curtain device 704 arranged inside the purification box 303 through a water delivery pipe 703. The bottom of the water curtain device 704 is connected to the water storage tank 701 through a water outlet pipe. The water curtain device 704 includes a water distribution seat 7041. The water distribution seat 7041 is connected to the water delivery pipe 703, and the water distribution seat 7041 is located at the inner top of the purification box 303. The water distribution seat 7041 is connected to a water collection seat 7043 through a wet curtain 7042.

[0042] When it is necessary to filter the dust-containing gas inside the protective cover 201, the intake air fan 301, the exhaust air fan 304 and the delivery water pump 702 are turned on. Under the action of the intake air fan 301, the dust-containing gas inside the protective cover 201 is transported into the purification box 303. The filter screen 3031 can filter large particle impurities in the gas. Under the action of the delivery water pump 702, the clean water in the water storage tank 701 is transported into the water delivery pipe 703. The clean water is injected into the water distribution seat 7041 in the water delivery pipe 703. Under the influence of gravity, the clean water evenly flows into the wet curtain 7042, so as to form a water curtain inside the wet curtain 7042. The dust-containing gas fully contacts with the water curtain formed by the wet curtain 7042, and the clean water is used to adsorb the particulate impurities contained in the gas, so as to achieve the effect of filtering the gas. And the waste water containing impurities finally flows into the water collection seat 7043, and the waste water flowing in is injected into the water storage tank 701 through the water collection seat 7043, so as to realize the recycling of the liquid. The exhaust air fan 304 can transport the filtered gas back into the protective cover 201 again. At the same time, using the water curtain device 704 for impurity filtration can increase the humidity of the gas inside the protective cover 201 to a certain extent, thereby reducing the possibility of static electricity generated by the polyester cotton yarn during the winding process.

[0043] Specifically, the drive motor 401 can drive the drive rod 402 to rotate.

A third bevel gear 4051 is arranged on the outside of the first rotating rod 405, and the third bevel gear 4051 meshes with the fourth bevel gear 4052. The fourth bevel gear 4052 is installed on the outside of the rotating vertical rod 4053. A fifth bevel gear 4054 is installed on the outside of the rotating vertical rod 4053, and the fifth bevel gear 4054 meshes with the sixth bevel gear 4055. The sixth bevel gear 4055 is installed on the outside of the transmission rod 4056, and one end of the transmission rod 4056 is connected to the worm 4057. The worm 4057 meshes with the worm gear 4058, and the worm gear 4058 is installed on the outside of the first lead screw mechanism 406. One end of the first lead screw mechanism 406 penetrates through the outside of the mounting box 4 and is rotatably connected to the mounting groove 407 arranged above the base 1. The first lead screw mechanism 406 is connected to the moving block 408 slidably arranged inside the mounting groove 407. The top of the moving block 408 is connected to the polyester cotton guide cylinder 4091 through the connecting rod 409. The other set of second bevel gears 404 is installed on the outside of the second rotating rod 6 rotatably arranged inside the mounting box 4. A driving wheel 601 is fixedly installed on the outside of the second rotating rod 6. The driving wheel 601 is connected to the driven wheel 604 arranged on the outside of the fan rod 603 through the transmission belt 602. The fan rod 603 is rotatably arranged inside the fan cylinder 605. The air outlet of the fan cylinder 605 is connected to the air injection pipe 607 through the delivery pipe 606. A plurality of air injection ports 6071 are opened on one side of the air injection pipe 607 close to the winding mechanism 5.

[0044] In a further embodiment, the winding mechanism 5 includes two sets of support plates 501, and a mounting cylinder 502 is rotatably arranged inside the support plates 501. The mounting cylinders 502 are connected through the winding 503.

[0045] In a still further embodiment, fan blades 6031 are symmetrically installed on the outside of the fan rod 603.

[0046] In use, the polyester-cotton yarn passes through the wire cylinder 206 and the polyester-cotton yarn guiding cylinder 4091 in sequence and winds around the outside of the winding bobbin 503. The driving motor 401 is turned on. Under the action of the driving motor 401, the driving rod 402 rotates to drive the winding bobbin 503 to rotate, so as to wind up the polyester-cotton yarn. At the same time, the driving rod 402 drives the second bevel gears 404 arranged on both sides to rotate through the first bevel gear 403. The second bevel gears 404 can drive the first rotating rod 405 and the second rotating rod 6 to rotate respectively. Under the action of the rotation of the first rotating rod 405, the fourth bevel gear 4052 and the rotating vertical rod 4053 are driven to rotate through the third bevel gear 4051. The rotating vertical rod 4053 can drive the fifth bevel gear 4054 to rotate synchronously, so as to drive the sixth bevel gear 4055 and the transmission rod 4056 to rotate. The transmission rod 4056 can drive the worm gear 4058 and the first lead screw mechanism 406 to rotate through the worm 4057. Under the action of the rotation of the first lead screw mechanism 406, the moving block 408 and the polyester-cotton yarn guiding cylinder 4091 move, so as to guide the polyester-cotton yarn and make the polyester-cotton yarn evenly distributed on the outside of the winding bobbin 503. At the same time, under the action of the rotation of the second rotating rod 6, the driving wheel 601 drives the driven wheel 604 and the fan rod 603 to rotate through the transmission belt 602, so that the fan blades 6031 rotate to generate wind. The generated wind is ejected through the air jet port 6071, so as to blow the dust on the surface of the polyester-cotton yarn wound around the winding bobbin 503.
