Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile equipment technology, specifically to a polyester filament guide. Background Technology
[0002] Polyester filament is the commercial name for polyester fiber in China. Its characteristics include resistance to chemicals and frequent washing, reducing fading and discoloration in clothing. Therefore, it's commonly used in hotel uniforms, stonewashed denim, sportswear, and children's clothing. Relatively speaking, polyester filament is more durable than rayon. During embroidery, even at high speeds, the high-tenacity polyester thread can withstand significant tension. Furthermore, it has extremely high fire resistance; even when the clothing is near a flame, it is not easily ignited. Currently, the production process of polyester filament often requires a yarn guide to transport the filaments. During this transport, insufficient thread tension can lead to knots and slippage, while excessive tension can cause breakage. Therefore, a yarn guide that can adjust the tension of the polyester filament is needed. Utility Model Content
[0003] The present invention provides a polyester filament guide to solve the above-mentioned technical problems, which can adjust the tension of the polyester filament.
[0004] To solve the above-mentioned technical problems, the technical solution of this utility model for a polyester filament guide is as follows:
[0005] The device includes a mounting angle plate; two connecting rods arranged front and rear are connected to one side of the mounting angle plate; a fixed panel is connected to the two connecting rods; an extension plate is connected above the fixed panel; a guide rod is connected to the side of the extension plate; a mounting panel is slidably connected to the guide rod and one of the connecting rods; a first guide roller is connected to the upper end of the mounting panel; a second guide roller and a third guide roller are respectively connected to the front and rear ends of the fixed panel; and locking seats for locking the position of the mounting panel are threaded onto the guide rod and the connecting rod for slidably connecting the mounting panel.
[0006] The third guide roller is detachably mounted on the rear end of the fixed panel; the first guide roller is detachably connected to the mounting panel.
[0007] The third guide roller is connected to a first mounting plate; a first positioning shaft is connected to the middle of the first mounting plate; a first positioning hole corresponding to the first positioning shaft is opened at the rear end of the fixed panel; the first positioning shaft is inserted into the first positioning hole, and the first mounting plate is connected to the fixed panel by bolts.
[0008] A second mounting plate is connected to the first guide roller; a second positioning shaft is connected to the middle of the second mounting plate; a second positioning hole corresponding to the second positioning shaft is opened at the upper end of the mounting panel; the second positioning shaft is inserted into the second positioning hole, and the second mounting plate is connected to the mounting panel by bolts.
[0009] The mounting panel has a long sliding groove, and the mounting panel is slidably connected to the guide rod and the connecting rod for sliding connection of the mounting panel through the long sliding groove.
[0010] The mounting angle plate has three mounting holes.
[0011] The technical effects achievable by this utility model are as follows: By sliding the mounting panel to the guide rod and one of the connecting rods, when it is necessary to adjust the tension of the polyester yarn, the position of the first guide roller is changed by adjusting the position of the mounting panel, thereby adjusting the tension of the polyester yarn; and the third guide roller and the first guide roller of this utility model are both connected by a detachable structure, which is convenient for replacement after damage. Attached Figure Description
[0012] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:
[0013] Figure 1 This is a schematic diagram of the structure of a polyester filament guide according to this utility model;
[0014] Figure 2 yes Figure 1 A diagram from another perspective;
[0015] Figure 3 This is an exploded view of a polyester filament guide device according to this utility model. Detailed Implementation
[0016] The present invention will now be described in further detail with reference to the accompanying drawings.
[0017] See Figures 1 to 3 .
[0018] A polyester filament guide includes a mounting plate 1 with three mounting holes 32 for easy bolt mounting onto a machine body. Two connecting rods 2, arranged front and rear, are connected to one side of the mounting plate 1. A fixed panel 3 is connected to the two connecting rods 2, and an extension plate 4 is connected above the fixed panel 3. A guide rod 5 is connected to the side of the extension plate 4, and a mounting panel 6 is slidably connected to one of the connecting rods 2. Specifically, the mounting panel 6 has a long groove 31, which slidably connects the mounting panel 6 to the guide rod 5 and the connecting rod 2 for slidable connection. A first guide roller 7 is connected to the upper end of the mounting panel 6, and a second guide roller 8 and a third guide roller 9 are connected to the front and rear ends of the fixed panel 3, respectively. Locking seats 10 for locking the position of the mounting panel 6 are threaded onto both the guide rod 5 and the connecting rod 2 for slidable connection.
[0019] This invention utilizes a design where the mounting panel 6 is slidably connected to the guide rod 5 and one of the connecting rods 2. When the tension of the polyester filament needs adjustment, the two locking seats 10 can be loosened, allowing the mounting panel 6 to slide along the guide rod 5 and the connecting rod 2, thereby adjusting the position of the mounting panel 6 itself, i.e., adjusting the position of the first guide roller 7. Since the polyester filament sequentially passes through the second guide roller 8, the first guide roller 7, and the third guide roller 9, the tension of the polyester filament changes when the position of the first guide roller 7 changes. When the desired tension is achieved, the two locking seats 10 are tightened again, limiting the mounting panel 6 and preventing it from sliding.
[0020] The third guide roller 9 is detachably installed on the rear end of the fixed panel 3. Specifically, the third guide roller 9 is connected to the first mounting plate 11, the first mounting plate 11 is connected to the middle of the first positioning shaft 12, the rear end of the fixed panel 3 is provided with a first positioning hole 13 corresponding to the first positioning shaft 12, the first positioning shaft 12 is inserted into the first positioning hole 13, and the first mounting plate 11 is connected to the fixed panel 3 by bolts.
[0021] The first guide roller 7 is detachably connected to the mounting panel 6. Specifically, the first guide roller 7 is connected to the second mounting plate 21, the second mounting plate 21 is connected to the middle of the second positioning shaft 22, the upper end of the mounting panel 6 is provided with a second positioning hole 23 corresponding to the second positioning shaft 22, the second positioning shaft 22 is inserted into the second positioning hole 23, and the second mounting plate 21 is connected to the mounting panel 6 by bolts.
[0022] The first guide roller 7 and the third guide roller 9 of this utility model are connected by a detachable connection structure, which makes it convenient to replace them after they are damaged.
