DETAILED DESCRIPTION

[0018] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0019] Embodiment: A tensioning mechanism of a computerized silk winding machine, such as Figure 1-Figure 3As shown, it comprises: a base 1, mounting frames 2 are fixedly installed on both sides of the top of the base 1, and the number of mounting frames 2 is two, mounting grooves 3 are opened on the opposite sides of the two mounting frames 2, a lifting plate 4 is slidably installed between the two mounting frames 2 through the mounting grooves 3, sliding rods 5 are fixedly installed inside the two mounting grooves 3, and the lifting plate 4 is slidably installed with the sliding rods 5 along the length direction of the sliding rods 5, the outside of the two sliding rods 5 and located above the lifting plate 4 are sleeved with first springs 6, the outside of the two sliding rods 5 and located below the lifting plate 4 are sleeved with second springs 7, the outer surface of the lifting plate 4 is tightly fitted with the inner surface of the mounting grooves 3, and the yarn is lifted from the first limiting wheel 13 The lifting plate 4 passes through the second limiting wheel 15. When the yarn tension is large, the lifting plate 4 moves downward along the length direction of the slide bar 5. At this time, the first spring 6 is reset, and the second spring 7 is compressed, thereby reducing the tension of the yarn. When the yarn tension is small, the lifting plate 4 moves upward along the length direction of the slide bar 5. At this time, the first spring 6 is compressed, and the second spring 7 is reset, thereby effectively increasing the tension of the yarn to avoid the loosening of the yarn and affecting the normal processing. There is friction between the lifting plate 4 and the slide bar 5, and there is also friction between the lifting plate 4 and the mounting frame 2, which plays a damping role to avoid the lifting plate 4 from moving up and down quickly and over a short distance, thereby improving practicality.

[0020] A screw rod 8 is rotatably installed on one side of the top of the lifting plate 4 through a bearing, an adjusting plate 9 is meshedly connected to the outside of the screw rod 8, a crank 10 is connected to the top keyway of the screw 8, and a limit rod 11 is fixedly installed on the other side of the top of the lifting plate 4. The adjusting plate 9 is slidably installed with the limit rod 11 along the length direction of the limit rod 11. The screw rod 8 can be effectively driven to rotate by turning the crank 10. The rotation of the screw 8 causes the adjusting plate 9 to slide along the length direction of the limit rod 11, thereby changing the distance between the first limit wheel 13 and the second limit wheel 15, thereby facilitating the installation of the yarn.

[0021] A first mounting seat 12 is fixedly installed at the bottom center point of the adjusting plate 9 by screws, and a first limiting wheel 13 is rotatably installed inside the first mounting seat 12 through a bearing. A second mounting seat 14 is fixedly installed at the top of the lifting plate 4 and located between the screw rod 8 and the limiting rod 11 by screws, and a second limiting wheel 15 is rotatably installed inside the second mounting seat 14 and located directly below the first limiting wheel 13 through a bearing. The first limiting wheel 13 and the second limiting wheel 15 are used to effectively guide the yarn and limit the yarn at the same time to prevent the yarn from suddenly loosening and falling from the second limiting wheel 15, thereby improving stability.

[0022] The working principle of the tensioning mechanism of a computerized silk winding machine provided by the utility model is as follows:

[0023] The first step: when the yarn tension is large, the lifting plate 4 moves downward along the length direction of the slide bar 5. At this time, the first spring 6 is reset, and the second spring 7 is compressed, thereby reducing the tension of the yarn. When the yarn tension is small, the lifting plate 4 moves upward along the length direction of the slide bar 5. At this time, the first spring 6 is compressed, and the second spring 7 is reset, thereby effectively increasing the tension of the yarn to prevent the yarn from loosening and affecting normal processing. There is friction between the lifting plate 4 and the slide bar 5, and there is also friction between the lifting plate 4 and the mounting frame 2, which plays a damping role to prevent the lifting plate 4 from moving up and down quickly and over a short distance, thereby improving practicality.

[0024] Step 2: By turning the crank 10, the screw rod 8 can be effectively driven to rotate. The rotation of the screw rod 8 causes the adjustment plate 9 to slide along the length direction of the limiting rod 11, thereby changing the distance between the first limiting wheel 13 and the second limiting wheel 15, which is convenient for the installation of the yarn. The yarn passes between the first limiting wheel 13 and the second limiting wheel 15. The first limiting wheel 13 and the second limiting wheel 15 are used to effectively guide the yarn and limit the yarn at the same time to prevent the yarn from suddenly loosening and falling from the second limiting wheel 15, thereby improving stability.

[0025] Finally, it should be pointed out that the above embodiments are only representative examples of the present utility model. Obviously, the present utility model is not limited to the above embodiments, and there are many variations. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model should be considered to belong to the protection scope of the present utility model.
