Description

Technical Field

[0001] This utility model relates to the field of twisting technology, and in particular to a guide-type aramid yarn twisting device for improving twisting uniformity. Background Technology

[0002] A twisting device is a piece of equipment used for twisting yarn. Its core function is to bond two or more single yarns together into a ply by twisting, while simultaneously enhancing the performance of the original yarn to meet the needs of textile processing. A guide-type aramid yarn twisting device refers to a twisting device with a guiding structure, which can guide the twisting of aramid yarn and improve the uniformity of the twisted yarn.

[0003] In existing guided aramid yarn twisting devices, the twisting drum performs the twisting operation, while the guiding structure guides the yarn. To further improve uniformity, the guiding structure typically moves back and forth with the movable rod. However, in existing twisting devices, the guiding structure is installed on the movable rod using a sleeve-type mounting method. When one of them needs to be disassembled and replaced, the adjacent guiding structure must be disassembled to make way, which is extremely inconvenient. Furthermore, the angle and relative height of the guiding structure cannot be adjusted after installation, resulting in poor adaptability and mediocre performance. Utility Model Content

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figures 1-4 As shown, a guide-type aramid yarn twisting device for improving twist uniformity includes a base 1, a feed spool 2 on the base 1, a support on the base 1, a twisting spool 3 on the support, a fixed partition 4 on the base 1, guide wheels 5 on the support, a movable rod 6 on the support, and a guide structure 7 on the movable rod 6, with each guide structure 7 corresponding to one of the twisting spools 3. A support leg 11 is located at the lower end of the base 1, and a tension wheel 8 is mounted on the fixed partition 4. A control box 9 connected to the support is located at the end of the base 1, and a control panel 10 is located on the control box 9.

[0019] When using the device for doubling twisting, the base 1 is placed on the support legs 11, and the guide structure 7 is installed on the movable rod 6. The yarn is placed on the pay-off drum 2, and the yarn end passes through the structure at the upper end of the pay-off drum 2. Then, the yarn end passes around the guide wheel 5, the tension wheel 8, and the guide structure 7, and finally connects to the doubling drum 3. After starting the entire device through the control panel 10 at the control box 9, the internal mechanism of the control box 9 drives the pay-off drum 2 and the doubling drum 3 to rotate, and the doubling drum 3 is used for doubling twisting. During the doubling twisting process, the tension wheel 8 provides tension, and the guide structure 7 plays a guiding role. At the same time, the internal moving mechanism of the control box 9 moves the movable rod 6 and the guide structure 7 back and forth, thereby achieving precise guidance and improving the uniformity of doubling twisting.

[0020] According to the above implementation scheme, the guide structure 7 includes a first mounting sleeve 701, a second mounting sleeve 702 and a circular groove 703. The first mounting sleeve 701 and the second mounting sleeve 702 are sleeved on the movable rod 6 through the circular groove 703, and the first mounting sleeve 701 is provided with a guide block. The guide structure 7 also includes a positioning post 704, a screw 705, a washer 706, a nut 707, an adjusting assembly 708, a guide frame 709, and a guide groove 710. The positioning post 704 and the screw 705 are fixedly connected, and the positioning post 704 is set on the second mounting sleeve 702. The positioning post 704 is inserted into the first mounting sleeve 701. The screw 705 passes through the first mounting sleeve 701. The washer 706 is sleeved on the screw 705. The nut 707 is threadedly connected to the screw 705. The guide frame 709 is installed on the first mounting sleeve 701 through the adjusting assembly 708, and the guide frame 709 is connected to the guide block on the first mounting sleeve 701. The guide groove 710 is formed on the guide frame 709.

[0021] When installing the guide structure 7, the first mounting sleeve 701 and the second mounting sleeve 702 are installed onto the movable rod 6 through the circular groove 703. The positioning pin 704 is inserted into the first mounting sleeve 701, and the screw 705 passes through the upper end of the first mounting sleeve 701. The washer 706 is fitted onto the screw 705, and the mounting nut 707 secures the two mounting sleeves. At this time, the guide frame 709 is installed on the first mounting sleeve 701 through the adjusting component 708 and the guide block. During guidance, the wire end passes through the guide groove 710 on the guide frame 709, and the movable rod 6 moves the guide structure 7 back and forth to achieve precise guidance. When needed, the nut 707 can be loosened to rotate the two mounting sleeves, thereby adjusting the angle of the guide frame 709. The relative height of the guide frame 709 can also be adjusted using the adjusting component 708, providing high flexibility and adaptability.

[0022] The adjusting assembly 708 includes a fixed block 7081, a rotating rod 7082, a rotating wheel 7083, a transmission belt 7084, an adjusting rod 7085, and a movable block 7086. The fixed block 7081 is fixed on the first mounting sleeve 701. The rotating rod 7082 is fixedly connected to the rotating wheel 7083 and is rotatably mounted on the fixed block 7081. The transmission belt 7084 is sleeved on the rotating wheel 7083. The adjusting rod 7085 is connected to the rotating rod 7082. The movable block 7086 is fixed on the guide frame 709 and is threadedly connected to the adjusting rod 7085.

[0023] When adjusting the height of the guide frame 709, the rotating wheel 7083 drives the corresponding rotating rod 7082 to rotate on the fixed block 7081. Under the drive of the transmission belt 7084, another rotating wheel 7083 will synchronously drive the corresponding rotating rod 7082 to rotate, so that the two adjusting rods 7085 rotate synchronously. Driven by the adjusting rods 7085, the movable block 7086 moves the guide frame 709 along the guide block, thereby adjusting the relative height of the guide frame 709. After the adjustment is completed, it can be used.

[0024] It should be noted that, through the set guide structure 7, the first mounting sleeve 701 and the second mounting sleeve 702 are set on the movable rod 6 through the circular groove 703, and are used in conjunction with the positioning column 704, screw 705 and nut 707, so that the entire guide structure 7 can be quickly installed and removed on the movable rod 6 without the need to operate other guide structures 7 to complete the replacement operation, which is highly convenient. At the same time, the setting of the first mounting sleeve 701 and the second mounting sleeve 702 allows the guide structure 7 to rotate on the movable rod 6, which improves the flexibility of use. The guide frame 709 is installed by using the adjustment component 708, and the relative height of the guide frame 709 can be adjusted as needed, which further improves the flexibility of use. The two rotating rods 7082 are equipped with rotating wheels 7083, and the rotating wheels 7083 are fitted with a transmission belt 7084, which can adjust the two rotating rods 7082 simultaneously, so that the two adjusting rods 7085 rotate synchronously, which can increase the stability of the guide frame 709 without affecting the rapid adjustment of the guide frame 709.
