The unwinding mechanism, the overhead feeding and drafting mechanism, the driving roller, and the coiling mechanism are arranged in sequence from front to back. A coiling pressure roller is arranged below the coiling mechanism, and the driving roller is 2 to 6 groups. The long fibers are unwound by the unwinding mechanism and then fed into the overhead feeding and drafting mechanism, and the fibers are drafted by using the different surface speeds of the front and rear rollers. And they are formed by a double pressure roller pulling-in coiling system to straighten and parallel the long fibers and achieve the purpose of doubling.

Secondly, the drawing frame is not convenient for quickly detecting the thickness of the long fiber sliver during transportation, and it is not convenient to adjust the thickness of the long fiber sliver according to the actual situation, reducing the practicality of use. For the above problems, it is necessary to improve the existing equipment. Summary of the Invention

Detailed implementation manners

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figure 1-8 , the present invention provides a technical solution: a long fiber drawing frame with an automatic adjustment function, according to Figure 1 , Figure 2 and Figure 3As shown in the figure, a fixed side plate 2 is provided on one side of the upper end of the chassis 1, and a first conveying roller frame 3 is provided on the top of the fixed side plate 2. Through the first conveying roller frame 3, it is convenient to guide and convey multiple laminated long fiber strips, so that the long fiber strips can be accurately conveyed into the drafting and adjusting mechanism 6 for processing. At the same time, a feeding mechanism 4 is provided on the upper end of the chassis 1 on the side of the fixed side plate 2. The feeding mechanism 4 includes a placing frame 401, and the bottom of the lower end of the placing frame 401 is connected to the chassis 1 through symmetrically arranged electric hydraulic cylinders 402. By driving the placing frame 401 to lift and lower through the electric hydraulic cylinders 402, it is convenient to adjust the height position of the long fiber bobbin 403 according to the tension of the long fiber strip during conveying. At the same time, the accuracy and stability of the placement of the long fiber bobbin 403 are also improved, effectively preventing deviation. On the inner side of the fixed side plate 2 close to the placing frame 401, symmetrically arranged guiding slide rails 201 are provided, and connecting slide seats 202 are slidably connected to both guiding slide rails 201. At the same time, the connecting slide seat 202 is connected to one side of the placing frame 401. By using the connecting slide seat 202 and the guiding slide rail 201 in combination, the placing frame 401 has a high stability during lifting and moving. At the same time, long fiber bobbins 403 are symmetrically arranged inside the placing frame 401. The two long fiber bobbins 403 are connected to the placing frame 401 through a driving connection assembly. The driving connection assembly includes insertion rods 404, and there are two insertion rods 404. At the same time, one end of the two insertion rods 404 penetrates the outside of the placing frame 401 and the middle of the long fiber bobbin 403 and is connected to a positioning seat 405 provided on one side inside the placing frame 401. Removable transmission gears 406 are connected to the outer sides of the two insertion rods 404, and the opposite sides of the two transmission gears 406 are meshed with both sides of a driving gear 409 provided in the middle. At the same time, the middle of the driving gear 409 is connected to the output end of a driving motor 408, and the lower end of the driving motor 408 is connected to an electric guide rail seat 407, and the electric guide rail seat 407 is installed in the middle of the outside of the placing frame 401.

[0030] During use, the electric guide rail base 407 drives the drive motor 408 and the drive gear 409 to move horizontally, so that the drive gear 409 meshes with the transmission gears 406 arranged on both sides. Then, the electric guide rail base 407 is started to drive the drive gear 409 and the transmission gear 406 to rotate, so that the plug rod 404 connected to the transmission gear 406 drives the long fiber bobbin 403 to rotate synchronously, and the long fiber strips on the two long fiber bobbins 403 are unwound synchronously. When it is necessary to replace the long fiber bobbin 403 after unwinding, the electric guide rail base 407 drives the drive motor 408 and the drive gear 409 to move horizontally in the reverse direction, so that the drive gear 409 is separated from the transmission gears 406 arranged on both sides. Then, the plug rod 404 is pulled out, so that the plug rod 404 is separated from the corresponding positioning seat 405. Then, the long fiber bobbin 403 is removed from the plug rod 404, and a new long fiber bobbin 403 is replaced. Then, the plug rod 404 is pushed again, so that the plug rod 404 is connected to the corresponding positioning seat 405, thus completing the replacement and improving the practicality of use.

[0031] According to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in the middle above the two long fiber bobbins 403 at the upper end of the placement frame 401, a thread combining assembly 410 is provided. The thread combining assembly 410 includes a rotating plate 4101, a rotating rod 4102 and an electromagnetic seat 4103. And a rotating rod 4102 is provided in the middle of one side of the rotating plate 4101. At the same time, both ends of the rotating rod 4102 are rotatably connected to the inside of the electromagnetic seat 4103. By rotating the rotating plate 4101, the rotating plate 4101 is placed vertically, so as to facilitate the replacement of the long fiber bobbin 403 arranged inside the placement frame 401. A metal block is provided inside the upper end of the rotating plate 4101 above one side of the electromagnetic seat 4103. Through the metal block, the rotating plate 4101 is magnetically connected and fixed to the electromagnetic seat 4103, so as to improve the stability of the placement of the rotating plate 4101. And a through hole 4104 is opened in the middle of the rotating plate 4101. At the same time, electric linear guide rails 4105 are symmetrically arranged on both sides inside the through hole 4104. A moving cylinder 4106 is arranged between the two electric linear guide rails 4105. And a rubber sleeve 4107 is arranged in the middle of the moving cylinder 4106. Through the rubber sleeve 4107, the multiple long fiber strips in contact with each other during drawing are not easily damaged and broken when moving and rubbing inside the moving cylinder 4106, improving the quality of the long fiber strips during transportation.

[0032] During use, one end of multiple long fiber strips is passed through the middle of the moving cylinder 4106 and fits inside the rubber sleeve 4107. Then, the electric linear guide rail 4105 drives the moving cylinder 4106 to move repeatedly inside the through hole 4104 opened in the rotating plate 4101, so as to adjust the tension of the long fiber strips during transportation and prevent the long fiber strips from shifting, improving the practicality of use.

[0033] According to Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, on the other side of the upper end of the chassis 1, there is a support frame 5. The support frame 5 is of an L-shaped structure. At the same time, the other end of the support frame 5 is connected to the other side of the fixed side plate 2. Near one side of the first conveying roller frame 3 at the upper end of the support frame 5, there is a drafting adjustment mechanism 6. The drafting adjustment mechanism 6 includes an adjustment box body 601. Through holes 6011 are symmetrically opened on both sides of the adjustment box body 601. Inside one of the through holes 6011, limiting rollers 6012 are symmetrically arranged. At the same time, a guiding roller 6013 is arranged at the lower end outside the limiting rollers 6012 of the adjustment box body 601. By using the limiting rollers 6012 and the guiding roller 6013 in combination, it is convenient to guide and convey the long fiber strips after drawing, improving the accuracy of conveying. A box cover 602 is arranged on the top of the adjustment box body 601. In the middle of the upper end of the box cover 602, there is an adjustment component 605. The adjustment component 605 includes a positioning frame 6051. Limiting seats 6052 are symmetrically arranged on the outside of the positioning frame 6051. At the same time, the limiting seats 6052 are connected to the upper end of the box cover 602 through positioning bolts 6053. On both sides inside the positioning frame 6051, guiding sliding seats 6054 are symmetrically arranged. The guiding sliding seats 6054 are of a loop structure. At the same time, both sides of the lifting plate 6055 are slidably connected to the inside of the two guiding sliding seats 6054. In the middle of the top of the lifting plate 6055, it is connected to the middle of the upper end of the positioning frame 6051 through an electric telescopic rod 6056. At the bottom of the lifting vertical rods 6057 arranged on both sides of the positioning frame 6051, they penetrate through the positioning frame 6051 and the lifting plate 6055 and are connected to the top of the corresponding positioning frames 6058. At the same time, a pressing roller 6059 is arranged inside the two positioning frames 6058. The positions of the two pressing rollers 6059 are on both sides above the positioning rollers 608. At the same time, protective sleeves are arranged on the outside of the two pressing rollers 6059. At the same time, the positions where the two pressing rollers 6059 are placed are at different heights.

[0034] During use, the electric telescopic rod 6056 is used to push the lifting plate 6055 to move inside the two guiding sliding seats 6054, so that the lifting plate 6055 drives the lifting vertical rods 6057 to rise and fall synchronously. Then, the positioning frames 6058 and the pressing rollers 6059 arranged at the lower ends of the lifting vertical rods 6057 also move synchronously, adjusting the distance between the pressing rollers 6059 and the positioning rollers 608, thereby facilitating the adjustment of the thickness of the long fiber strips after drawing and improving the practicality of use.

[0035] According to Figure 1 , Figure 2 and Figure 5As shown in the figure, an electrostatic eliminator assembly, a lower pressing roller 607 and a positioning roller 608 are sequentially arranged inside the adjustment box body 601. The electrostatic eliminator assembly includes an infusion pipe 603, a metering liquid discharge head 604 and an electrostatic elimination roller 606. The infusion pipe 603 penetrates through the box cover 602 and is connected to the metering liquid discharge head 604. At the same time, the top of the metering liquid discharge head 604 is detachably connected to one side of the lower end of the box cover 602. Electrostatic elimination rollers 606 are symmetrically arranged below the metering liquid discharge head 604. A liquid storage sleeve is sleeved outside the two electrostatic elimination rollers 606. At the same time, the outer side of the top of the upper electrostatic elimination roller 606 is attached to the bottom of the lower end of the metering liquid discharge head 604. The electrostatic elimination liquid is transported to the metering liquid discharge head 604 through the infusion pipe 603, so that the electrostatic elimination liquid is absorbed by the liquid storage sleeve arranged outside the upper electrostatic elimination roller 606. Then, while the long fiber strip is being transported, the long fiber strip is humidified and electrostatically eliminated, reducing the influence of static electricity on the processing process. A control box 609 is arranged on one side below the positioning roller 608 inside the adjustment box body 601. A thickness sensor 610 is arranged on one side of the control box 609 close to the lower pressing roller 607. At the same time, a monitoring device 611 is arranged on the upper end of the control box 609. The thickness sensor 610 and the monitoring device 611 are both prior arts. The thickness of the long fiber strip after drawing is detected by the thickness sensor 610 and the quality of the long fiber strip after drawing is detected by the monitoring device 611, improving the quality of the finished product.

[0036] According to Figure 1 、 Figure 2 、 Figure 7 and Figure 8 As shown in the figure, a square opening is formed on the other side of the upper end of the support frame 5 below the guide roller 6013. A guide assembly 7 is arranged inside the square opening. At the same time, the guide assembly 7 includes a self-locking guide rail 701, a moving frame 702 and a guide cylinder 703. Two self-locking guide rails 701 are symmetrically arranged. A moving frame 702 is symmetrically arranged between the two self-locking guide rails 701. At the same time, a guide cylinder 703 is arranged outside the middle of the two moving frames 702. By pushing the moving frame 702 to move between the two self-locking guide rails 701, the distance between the guide cylinders 703 is adjusted, so that the distance between the guide cylinders 703 is suitable for the transportation of long fiber strips of different thicknesses. A second conveying roller frame 8 is arranged on the inner side below the square opening of the support frame 5. Through the second conveying roller frame 8, the accuracy of the transportation and winding of the long fiber strip is further improved. A material receiving mechanism 9 is arranged below the second conveying roller frame 8. At the same time, the material receiving mechanism 9 is located on the other side of the upper end of the bottom frame 1. The material receiving mechanism 9 includes a material receiving cylinder 901. A connecting shaft 902 is detachably connected to the middle of the material receiving cylinder 901. At the same time, one end of the connecting shaft 902 is connected to a winding motor 904 arranged outside the support frame 5 through a coupling 903. The other end of the connecting shaft 902 penetrates through a positioning bearing 905 arranged on the support side plate 906 and extends to the outside of the positioning bearing 905. The bottom of the support side plate 906 is connected to the upper end of the bottom frame 1.

[0037] During use, the rewinding motor 904 drives the coupling 903, the connecting shaft 902 and the winding cylinder 901 to rotate, facilitating the winding of the long fiber strip onto the winding cylinder 901. When it is necessary to replace the wound winding cylinder 901, by pulling the connecting shaft 902, the connecting shaft 902 is separated from the coupling 903, and then the winding cylinder 901 is separated from the connecting shaft 902, so as to unload the wound winding cylinder 901. Then, a new winding cylinder 901 is connected to the connecting shaft 902, and the connecting shaft 902 is pushed to connect the connecting shaft 902 with the coupling 903, thus completing the replacement and improving the practicality of use.
