Description

Technical Field

[0001] The utility model relates to the technical field of synthetic fiber winding, in particular to a synthetic fiber winding constant force tensioning device. Background Art

[0002] Synthetic fiber is a chemical fiber made by spinning and post-processing artificially synthesized linear polymers with suitable molecular weight and solubility (or meltability). When the synthetic fiber is processed, it needs to be wound. In order to avoid partial folding during the winding process of the synthetic fiber, a tensioning device is needed to tension the synthetic fiber. However, when a general tensioning device is used, wrinkles will appear on the surface of the synthetic fiber, which is not conducive to the later use of the synthetic fiber. Summary of the invention

[0003] The utility model aims to provide a synthetic fiber winding constant force tensioning device to solve the problems raised in the above background technology.

[0004] A synthetic fiber winding constant force tensioning device comprises a fixed shaft, a guide wheel and a winding wheel: two fixed shafts are provided, a connecting shaft is provided on the outer side of the fixed shaft, a roller is provided on the side of the connecting shaft, a synthetic fiber is provided between the two rollers, a guide wheel is connected to the side of the synthetic fiber, and the synthetic fiber is wound on the surface of the winding wheel.

[0005] Preferably, a slideway is provided inside the fixed shaft, a first spring is arranged inside the slideway, a side of the first spring is connected to a first arc-shaped fixed rod, a slide groove for the first fixed rod to move is provided inside the side of the fixed shaft, and the first fixed rod is connected to the connecting shaft.

[0006] When the device is in use, when the synthetic fiber moves normally, the roller will continuously move with the synthetic fiber, and at this time the roller will also drive the connecting shaft to rotate a certain angle, and when the connecting shaft rotates, since the connecting shaft is connected to the first fixing rod, the first fixing rod will be driven into the interior of the slideway, thereby charging the first spring; then the connecting shaft will not rotate, thereby increasing the resistance of the roller and the synthetic fiber during rotation through the connecting shaft, thereby tightening the synthetic fiber;

[0007] During the winding process, the guide wheel guides the synthetic fiber, and when the winding wheel stops working, the first spring drives the connecting shaft and the roller to rotate in the opposite direction, thereby tensioning the synthetic fiber.

[0008] Preferably, a fixing track is opened inside the side of the connecting shaft, a limit block is rotatably arranged inside the fixing track, a spring plate is rotatably arranged on the side of the limit block, one side of the spring plate is arc-shaped, and the other side of the spring plate is flat, and a fixing groove with the same shape as the spring plate is opened inside the roller.

[0009] When the device is in use, when the synthetic fiber is normally wound and drives the roller to rotate, the arc side of the fixed groove will continuously contact the arc side of the spring sheet, thereby providing resistance for the roller when it rotates, and when the connecting shaft rotates in the opposite direction, the flat end of the spring sheet will contact the flat surface of the fixed groove, so that the spring sheet will drive the roller to rotate when it rotates in the opposite direction, thereby tightening the synthetic fiber.

[0010] Preferably, a slot is provided inside the connecting shaft, a second spring is arranged inside the slot, a second fixing rod is slidably arranged inside the slot, and a side surface of the second fixing rod is connected to a spring sheet.

[0011] When the device is in use, after the arc-shaped end of the spring sheet is squeezed, the spring sheet will rotate around the limit block, so that the second fixing rod will be retracted into the inside of the slot, at which time the second spring will be squeezed to shrink it, and then when the spring sheet is not squeezed, the second spring will push the second fixing rod to move so that the spring sheet returns to its original position.

[0012] Preferably, the side surface of the roller is provided with inclined friction lines.

[0013] When the synthetic fiber is wound normally, it will drive the roller to rotate. When the roller rotates, the friction lines will stretch the synthetic fiber to both sides, thereby preventing the synthetic fiber from wrinkling.

[0014] The beneficial effects of the utility model are:

[0015] 1. When the synthetic fiber drives the roller to rotate, the spring sheet will limit the fixed groove, so that resistance will be generated when the roller rotates, so that the synthetic fiber will have a fixed resistance when it is rolled up. At this time, the roller will cause friction lines to stretch the synthetic fiber when it rotates to avoid wrinkles on the synthetic fiber; when not rolling up, the first spring will drive the roller to rotate in the opposite direction to roll up the synthetic fiber.

[0025] When the device is in use, when the synthetic fiber moves normally, the roller 11 will continuously move with the synthetic fiber, and at this time, the roller 11 will also drive the connecting shaft 5 to rotate a certain angle, and when the connecting shaft 5 rotates, since the connecting shaft 5 is connected to the first fixing rod 4, the first fixing rod 4 will be driven to enter the interior of the slideway 2, so as to charge the first spring 3; then the connecting shaft 5 will not rotate, so that the resistance of the roller 11 and the synthetic fiber during rotation is increased through the connecting shaft 5, so as to tighten the synthetic fiber;

[0026] During the winding process, the guide wheel 14 guides the synthetic fiber, and when the winding wheel 15 stops working, the first spring 3 drives the connecting shaft 5 and the roller 11 to rotate in the opposite direction, thereby tensioning the synthetic fiber.

[0027] A fixed track is provided inside the side of the connecting shaft 5, and a limit block 6 is rotatably provided inside the fixed track.

[0028] When the device is in use, when the synthetic fiber is normally wound and drives the roller 11 to rotate, the arc side of the fixed groove 12 will continuously contact the arc side of the spring sheet 7, thereby providing resistance for the roller 11 during rotation, and when the connecting shaft 5 rotates in the opposite direction, the flat end of the spring sheet 7 will contact the flat surface of the fixed groove 12, so that the spring sheet 7 will drive the roller 11 to rotate when it rotates in the opposite direction, thereby tightening the synthetic fiber.
