[0001] The utility model relates to the technical field of tension of a loom, in particular to a tension control device of a loom. Background Art

[0002] A loom is a mechanical device used to make cloth. They form the structure of the cloth by weaving yarns or fibers together in a specific way. The loom pulls and reels the textile through a winding device, and the textile is rolled into a loop. During the winding process, tension needs to be applied to the textile to avoid wrinkles.

[0003] In the prior art, when a textile machine controls the tension of a textile cloth, an elastic force is applied to the textile cloth through a spring, and the elastic force applied to the textile cloth is used as tension, so that the textile cloth is in a taut state when it is rolled up.

[0004] However, since the internal parts of the loom rotate at high speed when weaving, the loom body will vibrate. Under the influence of the vibration of the loom, the spring will fluctuate, causing its tension on the textile cloth to constantly change, resulting in wrinkles when the textile cloth is rolled up. Utility Model Content

[0012] Optionally, when the reel reels up the textile fabric, the screw rod moves from bottom to top, and the distance between the screw rod and the reel is shortened.

[0013] Optionally, the speed reduction assembly includes a first gear, a second gear, a belt and an extension shaft, the first gear is fixedly installed on the end of the screw rod, the first gear is meshingly connected with the second gear, a belt is sleeved on the central rotating shaft of the second gear, the second gear is connected to the extension shaft through the belt, and the extension shaft is fixedly connected to the end of the winding shaft.

[0014] Optionally, the second gear is rotatably connected to the support plate frame via a rotating shaft, and among the first gear, the second gear and the extended shaft, the first gear has the largest diameter and the extended shaft has the smallest diameter.

[0029] Example 1

[0030] This embodiment provides a tension control device for a loom, such as Figure 1As shown, it includes a loom body 1, and two symmetrically arranged support plates 2 are fixedly installed on the side of the loom body 1, and the two support plates 2 are rotatably connected to the opposite sides with a winding shaft 3 and a guide roller 4; the winding shaft 3 and the guide roller 4 are conveyed with textile fabric, and the bottom of the tension adjustment roller 54 is in contact with the textile fabric.

[0031] As shown in the figure, the end of the reel 3 is fixedly connected to the motor through a rotating shaft, and the reel 3 reels the textile cloth, and the textile cloth moves from the loom body 1 to the reel 3. The reel 3, the guide roller 4 and the tension adjustment roller 54 support the textile cloth, and the textile cloth forms a V-shaped motion trajectory.

[0032] like Figure 2 and 3 As shown, a tension assembly 5 is provided on the support plate frame 2, and the tension assembly 5 includes a screw rod 52, a tension adjustment platform 53 and a tension adjustment roller 54. A guide groove 51 perpendicular to the horizontal plane is opened on the support plate frame 2, and both ends of the screw rod 52 rotate at the guide groove 51 on the support plate frame 2. The rod body of the screw rod 52 is threadedly connected to the tension adjustment platform 53, and the tension adjustment platform 53 slides at the guide groove 51 on the support plate frame 2.

[0033] A deceleration component 6 is arranged between the winding shaft 3 and the tension component 5. The winding shaft 3 drives the screw rod 52 to rotate through the deceleration component 6. When the screw rod 52 rotates, the guide groove 51 limits the tension adjustment platform 53 to prevent the tension adjustment platform 53 from rotating with the screw rod 52 and being unable to rise or fall.

[0034] When the winding shaft 3 winds up the textile fabric, as more and more textile fabric is placed on the winding shaft 3, the tension on the textile fabric between the guide groove 51 and the tension adjustment platform 53 becomes greater and greater. The winding shaft 3 utilizes the speed reduction component 6 to drive the screw rod 52 to rotate, so that the tension adjustment platform 53 moves upward. The tension adjustment platform 53 raises the height of the tension adjustment roller 54, thereby reducing the tension on the textile fabric between the guide groove 51 and the tension adjustment platform 53, and preventing the textile fabric from cracking due to excessive tension.

[0035] like Figure 2 As shown, two screw rods 52 are provided and are respectively located on two support plate frames 2, and both ends of the screw rod 52 are rotatably connected to the support plate frames 2, and the two tension adjustment platforms 53 are rotatably connected to the opposite sides thereof with tension adjustment rollers 54. The two tension adjustment platforms 53 are moved upward by the two screw rods 52, so that both ends of the tension adjustment rollers 54 move upward at the same time, so that the tension adjustment rollers 54 are always parallel to the winding shaft 3.

[0036] In this embodiment, as the winding shaft 3 is wound, the textile cloth thereon becomes thicker and thicker. At this time, the winding shaft 3 uses the speed reduction component 6 to rotate the screw rod 52, and the tension adjustment roller 54 on the screw rod 52 moves upward to reduce the distance between it and the winding shaft 3, thereby reducing the tension applied by the guide groove 51 to the textile cloth, thereby avoiding excessive tension causing the textile cloth to crack.

[0037] Example 2

[0038] Based on Example 1, this embodiment proposes a tension control device for a loom, such as Figure 3 As shown, the speed reduction assembly 6 includes a first gear 61, a second gear 62, a belt 63 and an extension shaft 64. The first gear 61 is fixedly installed on the end of the screw rod 52, the first gear 61 is meshingly connected with the second gear 62, the belt 63 is sleeved on the central rotating shaft of the second gear 62, the second gear 62 is connected to the extension shaft 64 through the belt 63, and the extension shaft 64 is fixedly connected to the end of the winding shaft 3.

[0039] The extension shaft 64 is driven to rotate by the rotation of the winding shaft 3, and the extension shaft 64 drives the first gear 61 to rotate by the belt 63 and the second gear 62, so that the screw rod 52 rotates to lift the tension adjustment roller 54.

[0040] like Figure 3 As shown, the second gear 62 is rotatably connected to the support plate frame 2 via a rotating shaft, and among the first gear 61, the second gear 62 and the extension shaft 64, the first gear 61 has the largest diameter and the extension shaft 64 has the smallest diameter. The rotation ratio of the winding shaft 3 and the first gear 61 is adjusted by the diameter ratio of the first gear 61, the second gear 62 and the extension shaft 64, that is, the rotation ratio of the screw rod 52 is adjusted.

[0041] In this embodiment, the rotation ratio of the winding shaft 3 and the first gear 61 is adjusted by adjusting the diameter ratio of the first gear 61, the second gear 62 and the extension shaft 64, so that the winding shaft 3 rotates multiple times to drive the first gear 61 to rotate one circle, thereby preventing the screw rod 52 from rotating too fast, and the tension adjustment table 53 drives the tension adjustment roller 54 to rise quickly and separate from the textile cloth, making it impossible to apply tension to the textile cloth.

[0042] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
