Description

Technical Field

[0001] This utility model relates to the field of polyester filament technology, and in particular to a polyester filament guide. Background Technology

[0002] Polyester yarn is resistant to chemicals and frequent washing, reducing fading and discoloration in clothing. It is used in the manufacture of hotel uniforms, stonewashed denim, sportswear, and children's clothing. During the processing and production of polyester yarn, a polyester yarn guide is typically used to guide the yarn.

[0003] Chinese utility model patent CN220886525U discloses a polyester filament guide, comprising: a base with two connecting holes; a lifting assembly including a rectangular cylinder, a rectangular rod, a threaded rod, and a rotating rod; and a filament guide assembly including a U-shaped plate, a round rod, and a filament guide roller. The U-shaped plate is fixedly mounted on the top of the rectangular rod, and one end of the round rod is rotatably mounted on one end of the U-shaped plate. The round rod passes through the filament guide roller and is rotatably mounted.

[0004] Regarding the aforementioned technologies, the inventors believe that the following drawbacks exist: the rotation direction of the guide roller in the above-mentioned device is fixed, and it can only guide polyester filaments in a single direction. However, in actual industrial production scenarios, due to differences in the installation position and layout of different machines and equipment, the guiding direction of the guide roller also needs to be changed. Currently, the commonly used solution is to use various connectors to change the guiding direction by altering the installation position of the guide, which requires preparing multiple connectors and is quite inconvenient. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a polyester filament guide.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a polyester filament guide, comprising a base plate, a fixing ring provided on the base plate, a rotating plate horizontally rotatably provided inside the fixing ring, a fixing component for fixing the rotating plate and the fixing ring provided on the rotating plate, a plurality of vertically spaced rotating holes provided on the rotating plate, a rotating disk rotatably provided inside the rotating holes, a mounting groove provided inside the rotating disk, a main guide roller rotatably provided inside the mounting groove, a toothed ring concentrically provided on one side of the rotating disk, a gear rotatably provided between two adjacent toothed rings, and the gear meshing with both adjacent toothed rings.

[0007] By adopting the above technical solution, a base plate, a fixed ring, a rotating plate, and a fixed assembly are set up. Rotating the rotating plate changes the position of the rotating disk, and rotating the rotating disk changes the rotation direction of the main guide roller. The rotating plate and rotating disk work together to achieve adjustment of multiple guide directions. When one of the rotating disks rotates, it drives the toothed ring connected to it to rotate. Since the gear meshes with two adjacent toothed rings, several toothed rings can rotate synchronously, thereby allowing several rotating disks to rotate synchronously for adjustment. This eliminates the need to prepare multiple connecting parts to change the installation position of the guide roller to adjust the guide direction, making it more convenient.

[0008] Furthermore, the fixing component includes a connecting plate disposed on one side of the rotating disk, the connecting plate having a screw hole, a bolt being screwed into the screw hole, and the orthographic projection of the end of the bolt being located in the area of ​​the annular side of the fixing ring.

[0009] By adopting the above technical solution, a connecting plate, screw holes, and bolts are set. When the rotating plate rotates, it drives the connecting plate to rotate. After the position of the rotating disk is adjusted, the bolts are rotated so that the ends of the bolts abut against the side of the fixing ring, thereby fixing the position of the connecting plate and the rotating plate.

[0010] Furthermore, the fixing ring has several circumferentially spaced fixing holes on one side near the bolt.

[0011] By adopting the above technical solution, several circumferentially spaced fixing holes are opened on the side of the fixing ring near the bolt. Rotating the bolt causes the bolt end to be inserted into the fixing hole, which improves the fixing effect on the connecting plate and the rotating plate.

[0012] Furthermore, the rotating hole has three openings, and the gear has two rotating configurations.

[0013] Furthermore, one of the gears is concentrically provided with a mounting shaft, and a handle is provided at the end of the mounting shaft away from the gear.

[0014] By adopting the above technical solution, an installation shaft and a handle are set up. Turning the handle will drive the installation shaft to rotate, thereby driving the gear connected to the installation shaft to rotate.

[0015] Furthermore, the rotating plate has mounting posts on both sides of the gear that is not connected to the mounting shaft. The ends of the two mounting posts share a mounting plate. The mounting plate has two spaced sliding holes. A sliding rod is slidably installed in the sliding holes. The ends of the two sliding rods near the gear share a pressure plate. A threaded rod is rotatably installed on the side of the pressure plate away from the gear. The mounting plate is helically connected to the threaded rod through a threaded hole. A rotating cap is installed on the end of the threaded rod away from the pressure plate.

[0016] By adopting the above technical solution, a mounting column, mounting plate, sliding rod, pressure plate, and rotating cap are set up. Rotating the rotating cap drives the threaded rod to rotate. When the threaded rod rotates, it moves relative to the mounting plate, thereby driving the clamping plate to move along the length of the sliding rod. When the clamping plate abuts against an adjacent gear, the gear is fixed and cannot rotate. Since several gear rings and gears are all linked, when one gear is fixed, all gears and gear rings are fixed, thus fixing the position of several rotating disks.

[0017] Furthermore, an auxiliary guide roller is rotatably disposed within the mounting groove, the axis of which is parallel to the axis of the main guide roller.

[0018] Furthermore, two weight-reducing grooves are symmetrically formed on the rotating plate.

[0019] In summary, this utility model has the following beneficial effects: In this application, rotating the rotating plate changes the position of the rotating disk, and rotating the rotating disk changes the rotation direction of the main guide roller. The rotating plate and rotating disk work together to achieve adjustment of multiple guiding directions. When one of the rotating disks rotates, it drives the toothed ring connected to it to rotate. Since the gear meshes with two adjacent toothed rings, several toothed rings can rotate synchronously, thereby allowing several rotating disks to rotate synchronously for adjustment. It eliminates the need to prepare several connecting parts to change the installation position of the guide wire to adjust the guide wire direction, making it more convenient.

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] like Figure 1-5 As shown in the illustration, this application discloses a polyester filament guide, including a base plate 10, a fixing ring 11, a rotating plate 13, and a fixing assembly 20. The fixing ring 11 is disposed on the base plate 10, and the rotating plate 13 is horizontally rotatably disposed inside the fixing ring 11. The rotating plate 13 is a circular plate, and its axis coincides with the center line of the fixing ring 11. The fixing assembly 20 is disposed on the rotating plate 13 and is used to fix the rotating plate 13 to the fixing ring 11. The rotating plate 13 has several vertically spaced rotating holes, and a rotating disk 30 is rotatably mounted within each hole. The axis of the rotating disk 30 is parallel to the axis of the rotating plate 13. A mounting groove 31 is provided within the rotating disk 30, and a main guide roller 32 is rotatably mounted within the mounting groove 31. A toothed ring 33 is concentrically mounted on one side of the rotating disk 30, and a gear 34 is rotatably mounted between two adjacent toothed rings 33. The gear 34 meshes with both adjacent toothed rings 33. Rotating the rotating plate 13 changes the position of the rotating disk 30, thus changing the rotation direction of the main guide roller 32. The rotating plate 13 and the rotating disk 30 work together to adjust various guiding directions. When one of the rotating disks 30 rotates, it drives the toothed rings 33 connected to it to rotate. Because the gear 34 meshes with both adjacent toothed rings 33, several toothed rings 33 can rotate synchronously, allowing several rotating disks 30 to rotate synchronously for adjustment. This eliminates the need for multiple connecting parts to change the installation position of the guide wire to adjust the guide wire direction, making it more convenient.

[0028] Specifically, two weight-reducing grooves 14 are symmetrically formed on the rotating plate 13. The fixing assembly 20 includes a connecting plate 21 disposed on one side of the rotating disk 30. The connecting plate 21 has screw holes, the center line of which is parallel to the axis of the rotating plate 13. A bolt 22 is screwed into the screw hole. The orthographic projection of the end of the bolt 22 is located in the area of ​​the annular side of the fixing ring 11. When the rotating plate 13 rotates, it drives the connecting plate 21 to rotate. After the position of the rotating disk 30 is adjusted, the bolt 22 is rotated so that the end of the bolt 22 abuts against the side of the fixing ring 11, fixing the position of the connecting plate 21 and the rotating plate 13. The fixing ring 11 has several circumferentially spaced fixing holes 12 on the side adjacent to the bolt 22. Rotating the bolt 22 causes the end of the bolt 22 to engage in the fixing holes 12, which improves the fixing effect of the connecting plate 21 and the rotating plate 13.

[0029] During setup, three rotating holes are provided, and two of the gears 34 are rotatably positioned. One of the gears 34 has a concentric mounting shaft 40. A handle 41 is located at the end of the mounting shaft 40 furthest from the gear 34. Rotating the handle 41 rotates the mounting shaft 40, thereby rotating the gear 34 connected to the mounting shaft 40. On the rotating plate 13, mounting posts 50 are provided on both sides of the gear 34 not connected to the mounting shaft 40. The axis of the mounting posts 50 is parallel to the axis of the rotating plate 13. A mounting plate 51 is shared at the ends of the two mounting posts 50 furthest from the rotating plate 13. Two spaced sliding holes are provided on the mounting plate 51, and sliding rods 52 slide within these holes. A pressure plate 53 is shared at the ends of the two sliding rods 52 adjacent to the gear 34. The pressure plate 53 and the sliding rods 52 move synchronously. A threaded rod 54 is rotatably mounted on the side of the pressure plate 53 away from the gear 34. The axis of the threaded rod 54 is parallel to the axis of the slide rod 52. The mounting plate 51 is screwed to the threaded rod 54 through a threaded hole. A rotating cap 55 is provided at the end of the threaded rod 54 away from the pressure plate 53. Rotating the rotating cap 55 drives the threaded rod 54 to rotate. When the threaded rod 54 rotates, it moves relative to the mounting plate 51, thereby driving the clamping plate to move along the length of the slide rod 52. When the clamping plate abuts against the adjacent gear 34, the gear 34 is fixed and cannot rotate. Since the gears 34 and the toothed rings 33 are all linked, when one gear 34 is fixed, all the gears 34 and the toothed rings 33 are fixed, thereby fixing the position of the rotating disks 30.

[0030] In a specific configuration, an auxiliary guide roller 35 is also rotatably mounted inside the mounting groove 31. The axis of the auxiliary guide roller 35 is parallel to the axis of the main guide roller 32. The main guide roller 32 includes a main rotating column and a main annular groove formed on the outer wall of the main rotating column. The auxiliary guide roller 35 includes an auxiliary rotating column and an auxiliary annular groove formed on the outer wall of the auxiliary rotating column. The diameter of the main rotating column is larger than the diameter of the auxiliary rotating column.

[0031] The operating principle of the polyester filament guide in this embodiment is as follows: Rotating the rotating plate 13 changes the position of the rotating disk 30. Then, rotating the bolt 22 inserts its end into the fixing hole 12, thus fixing the rotating plate 13. Next, rotating the handle 41 drives the mounting shaft 40 and the gear 34 connected to it to rotate, allowing several gear rings 33 and the rotating disk 30 to rotate synchronously for adjustment. Then, rotating the rotating cap 55 drives the threaded rod 54 to rotate, causing the clamping plate to move and contact the adjacent gear 34, fixing it in place, thus fixing all gear rings 33 and the rotating disk 30. Finally, the nylon filament is passed between the corresponding active guide roller and auxiliary guide roller 35.

[0032] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
