[0040] Polyester mesh is a mesh woven by textile machinery using different weaving methods. Polyester mesh is one of the main drying and filtering materials in the world, so it is widely used in the papermaking field. It is an indispensable and expensive consumable dehydration equipment in the papermaking industry. When used in the papermaking field, it is also called polyester papermaking mesh. It is one of the main drying and filtering materials and is widely used in papermaking, sewage treatment, sugar making, pharmaceuticals, ceramics, food, printing, coal washing and other industries.

[0041] The existing polyester mesh is woven from multiple monofilaments, which are usually wound on a bobbin. When weaving the polyester mesh, the monofilaments need to be pulled and transported to the weaving equipment through a feeding device. However, during the transportation of the polyester mesh, the tension of the polyester mesh cannot be adjusted, which makes the polyester mesh easily too tight and break, or too loose and easily knotted.

[0042] The following is combined with Figures 1 to 5 The utility model is described in further detail.

[0043] Reference Figures 1 to 4As shown, the polyester mesh feeding bobbin includes a base 100, a driving assembly 200 and an elastic assembly 300. The driving assembly 200 and the elastic assembly 300 are sequentially arranged on the base 100 from front to back. The elastic assembly 300 includes a slider 310, a compression spring 320, a mounting plate 330, an equal height screw 340, an extrusion roller 350 and a second column 360. Two second columns 360 are provided. The two second columns 360 are symmetrically arranged on the base 100. The second columns 360 are provided with mounting grooves 362. The mounting plate 330 is fixed to the second columns 360 and covers the top of the mounting grooves 362. The slider 310 is located below the mounting plate 330 and in the mounting grooves 362 of the second columns 360. The block 310 can slide in the vertical direction. An opening is provided in the middle of the slider 310, and the opening is used to connect with the squeezing roller 350. Two countersunk holes and two threaded holes are provided on the top of the slider 310. One end of the compression spring 320 abuts against the end face of the countersunk hole, and the other end abuts against the bottom surface of the mounting plate 330. An equal height screw 340 is provided above the mounting plate 330. The equal height screw 340 passes through the screw through hole of the mounting plate 330 and the compression spring 320, and is connected to the slider 310 through the threaded hole. The equal height screw 340 can slide in the vertical direction with the slider 310. The squeezing roller 350 is rotatably connected to the slider 310 through the opening in the middle of the slider 310. The squeezing roller 350 is mounted between the sliders 310 of the two second columns 360. The compression spring 320 of the elastic component 300 between the mounting plate 330 and the slider 310 can enable the slider 310 to return to a preset position after rising or falling. When the polyester mesh is being transported, the driving component 200 is then wound around the squeezing roller 350 on the elastic component 300. The squeezing roller 350 can provide a certain tension for the polyester mesh, so that the tension of the polyester mesh is maintained within an appropriate range.

[0044] It should be noted that when the polyester mesh is fed, the polyester mesh wire is driven by the driving component 200 to reach the elastic component 300, and the polyester mesh wire is wound around the squeezing roller 350. Since a compression spring 320 is arranged between the mounting plate 330 and the slider 310, the slider 310 is located in the mounting groove 362 of the second column 360 and can move in the vertical direction. The equal height screw 340 is connected to the slider 310, and the squeezing roller 350 is mounted between the two sliders 310, so that the squeezing roller 350 can move along the vertical direction with the slider 310, and the equal height screw 340 can limit the sliding distance of the slider 310. When the polyester mesh and the squeezing roller 350 are wound too tightly, the compression spring 320 will be compressed, the slider 310 will slide downward, and the squeezing roller 350 will move downward, so that the polyester mesh will not be too tight and break; when the polyester mesh and the squeezing roller 350 are wound too loose, the compression spring 320 will be elastically deformed, the slider 310 will slide upward, and the squeezing roller 350 will move upward to squeeze the polyester mesh, so that the polyester mesh will be tightened to avoid knotting during winding. The elastic component 300 can adjust the tension of the polyester mesh during the transportation process, so that the polyester mesh is not easy to break due to being too tight or to be knotted due to being too loose, and replacing the compression spring 320 with different spring coefficients can also provide different tensions for the polyester mesh.

[0045] It is understandable that, referring to Figure 1 , Figure 3 and Figure 4 As shown, the outer walls of both sides of the slider 310 are provided with limiting grooves, which are arc-shaped and concave inwards, and the second column 360 is provided with an arc-shaped protrusion 361, which can match the limiting groove. Under the cooperation of the limiting groove and the protrusion 361, the slider 310 can slide along the length direction of the protrusion 361, that is, the slider 310 can slide along the vertical direction. When installing the slider 310 and the second column 360, the limiting groove and the protrusion 361 can also be used for guidance, so that the slider 310 and the second column 360 can be conveniently installed in alignment.

[0046] It is understandable that, referring to Figure 1 , Figure 3 and Figure 4 As shown, the protrusion 361 is located in the mounting groove 362 of the second column 360, the mounting plate 330 of the elastic component 300 is fixedly mounted on the second column 360 to cover the mounting groove 362, and the slider 310 cooperates with the protrusion 361 of the second column 360 so that the slider 310 can move in the mounting groove 362 along the vertical direction.

[0047] It is understandable that, referring to Figure 1As shown, the driving component 200 includes a first column 210, a driver 220 and a bobbin 230. The first column 210 is fixed to the base. The first column 210 is provided with a mounting hole. The driver 220 is passed through the mounting opening of the first column 210. The driver 220 can be a reduction stepper motor. The output end of the driver 220 passes through the mounting hole and is located on the other side of the first column 210. The bobbin 230 is connected to the output end of the driver 220 and can rotate under the drive of the driver 220. The bobbin 230 rotates so that the polyester mesh wound on the bobbin 230 is transported to the elastic component 300 at the rear.

[0048] It is understandable that, referring to Figure 1 As shown, it also includes a wire assembly 400. The driving assembly 200, the elastic assembly 300 and the wire assembly 400 are arranged on the base from front to back. The wire assembly 400 includes a third column 410 and a wire barrel 430. The third column 410 is fixed on the base. The wire barrel 430 is rotatably set on the third column 410. The polyester mesh is wound on the wire barrel 430. The wire barrel 430 can play a guiding role. After passing through the elastic assembly 300, the polyester mesh is guided by the wire assembly 400 and then enters the next process.

[0049] It is understandable that, referring to Figure 1 As shown, the wire assembly 400 further includes a handle 420, which is connected to a wire barrel 430. The handle 420 is located above the third column 410, and the wire barrel 430 can be fixed in the third column 410 through the handle 420. When the wire barrel 430 needs to be removed, it is only necessary to unscrew the handle 420 and then remove the wire barrel 430, and the process of installing and removing the wire barrel 430 is convenient and quick.

[0050] It is understandable that, referring to Figure 1 and Figure 4 As shown, the guide rod 500 is also included. The guide rod 500 is fixed between the two second uprights 360. The guide rod 500 is located below the squeezing roller 350. The middle part of the guide rod 500 is provided with an arc portion, which is convex toward the squeezing roller 350. Driven by the driving assembly 200, the polyester mesh passes through the bobbin 230, the arc portion of the guide rod 500, the squeezing roller 350 in sequence, and finally passes through the wire bobbin 430 to be sent to the next process. The guide rod 500 can guide the polyester mesh between the bobbin 230 and the squeezing roller 350. When the driver 220 is started to wind the polyester mesh, the polyester mesh is tightened due to the obstruction of the arc portion of the guide rod 500, so that the polyester mesh will be scraped by the arc portion on the guide rod 500 at every place in the tight state. If the polyester mesh is of poor quality during production, it will break, so the quality of the poor quality polyester mesh can be screened, which can effectively reduce the phenomenon of polyester mesh breaking.

[0051] It is understandable that, referring to Figure 1 and Figure 5 As shown, the guide rod 500 is located above the bobbin 230, and the squeezing roller 350 is located above the guide rod 500, that is, the bobbin 230, the guide rod 500 and the squeezing roller 350 are arranged from bottom to top. Of course, the arrangement from bottom to top here does not mean arrangement from bottom to top in the same vertical direction, but the bobbin 230, the guide rod 500 and the squeezing roller 350 are arranged from bottom to top in spatial position distribution. The polyester mesh is wound on the bobbin 230, driven by the driver 220 to be transported backward, passes through the guide rod 500 and then passes through the squeezing roller 350, and is finally transported to the wire bobbin 430.

[0052] It is understandable that, referring to Figure 2 and Figure 3 As shown, mounting holes are provided on both sides of the mounting plate 330, and threaded holes are opened at positions of the second column 360 corresponding to the mounting holes of the mounting plate 330. Screws can be passed through the mounting holes of the mounting plate 330 and the threaded holes of the second column 360 to fix the mounting plate 330 on the second column 360, so that the mounting plate 330 can cover the mounting groove 362 of the second column 360.

[0053] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
