Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of sewing thread testing, in particular to a multifunctional sewing thread flame retardant performance testing twisting device. Background Art
[0002] Currently, when testing the flame retardancy of sewing thread, a twisting device is typically used to twist the sewing thread. Existing twisting devices for testing the flame retardancy of sewing thread include a device base and a device frame. The device base is a rectangular parallelepiped, embedded with two rotating columns, a transmission device, a switch device, and a motor, and externally connected to a control panel. The rotating columns are cylindrical and mounted on the left and right sides of the device base, placed on top of the transmission device, and connected to two clamps for clamping the sewing thread. The clamps use an extrusion method to secure the arranged sewing thread. However, this existing twisting device for testing the flame retardancy of sewing thread can only fold and twist a single sewing thread when in use. The number of twisted threads is small, and the rotating end is the beginning of the sewing thread. When the sewing thread is long, the two ends of the sewing thread are easily tangled together during rotation, making it inconvenient to use. Utility Model Content

[0016] The present invention will be described in detail below with reference to the accompanying drawings. Figure 1 As shown, a multifunctional sewing thread flame retardant performance test twisting device includes a base 1, a linear motor 2 is fixedly installed in a groove opened in the middle of the base 1, a motor 3 is fixedly installed on the upper part of the slider of the linear motor 2, and slide grooves 6 are opened on the front and rear sides of the upper part of the base 1. The slide grooves 6 are arranged parallel to the linear motor 2. A sliding rod 7 is slidably connected to the upper part of each of the slide grooves 6, and a wire ring assembly 8 is installed between the two sliding rods 7. A spool assembly 9 is fixedly installed on one side of the base 1.
[0017] In this embodiment, combined with the Figure 2As shown, the wire harness ring assembly 8 includes a circular ring 81, a center column 84 is provided in the middle of the circular ring 81, and a connecting frame 85 is welded and fixed between one end of the center column 84 and the circular ring 81, and an arc seat 82 is provided in the circular ring 81. The outer side of each of the arc seats 82 is provided with a groove, and a ball bearing is installed in the groove. A screw 83 is installed at the ball bearing. Each of the screws 83 passes through the circular ring 81 and the screw 83 is threadedly connected to the circular ring 81. When each sewing thread passes through the circular ring 81, each sewing thread is passed through each arc seat 82 and the center column 84 respectively, and the screw 83 is rotated to make the arc seat 82 fit with the center column 84, thereby separating the sewing threads and preventing the sewing threads from being entangled.
