[0002] In the production process of spinning machinery, the two-for-one twister is one of the indispensable equipment. The two-for-one twister is mainly used to twist single yarn to form ply yarn to increase the strength and elasticity of the yarn. The two-for-one twister usually includes a driving component and a component for placing the yarn roll. However, in the existing two-for-one twisting mechanism, there are some problems with the placement of the yarn roll and the twisting process.

[0003] First, the existing two-for-one twisting mechanism often lacks a stable yarn roll placement structure. Therefore, the yarn roll may slip or shift during the placement process, which not only affects the uniformity of yarn stretching, but also may affect the normal supply of yarn rolls, increasing the difficulty of work.

[0004] Secondly, the existing two-for-one twisting mechanism is complicated to operate during the construction and use process. For example, the connection step between the column and the crossbar requires certain skills and strength, which may require extra time and effort for the operator.

[0005] Finally, when the existing two-for-one twisting mechanism is twisting the yarn, the cooperation between the driving component and the column, cross bar and threading ring is not tight enough, which may cause problems such as yarn entanglement and breakage during rotation, thereby affecting the quality of the yarn.

It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0028] See also Figure 1-7 This is a two-for-one twisting mechanism of a two-for-one twisting machine, which mainly includes a support assembly 1. The support assembly 1 includes a bottom plate 11, which provides a stable foundation for the entire two-for-one twisting mechanism. The upper end surface of the bottom plate 11 is fixedly connected with a first positioning ring 12 and a second positioning ring 13, which are coaxially arranged to stably fix the wire coil. On the first positioning ring 12 and the second positioning ring 13, a first anti-slip strip 121 and a second anti-slip strip 131 are respectively arranged, which can prevent the wire coil from sliding during operation and ensure the stable placement of the wire coil.

[0029] The bottom of the bottom plate 11 is provided with a motor 14, and the output end of the motor 14 is provided with a threaded column 141, which is the power source for driving the entire two-for-one twisting mechanism. The threaded column 141 is connected to a column 2, which provides height for the two-for-one twisting mechanism and can rotate. The top of the column 2 is plugged with a crossbar 3, which can rotate to drive the wire coil to twist.

[0030] See also Figure 1-3In order to increase the stability of the wire coil placement, a first anti-slip strip 121 is fixedly connected to the outer side of the first positioning ring 12, and the first anti-slip strips 121 are evenly spaced around the central axis of the first positioning ring 12. Similarly, a second anti-slip strip 131 is fixedly connected to the outer side of the second positioning ring 13 to increase the stability of the wire coil placement.

[0031] See also Figure 2-4 The bottom end of the column 2 is fixedly connected with a connecting seat 21, and the bottom end of the connecting seat 21 is provided with a threaded groove 211, which can be screwed onto the threaded column 141. In order to prevent the column 2 from sliding during the rotation process, an anti-slip strip 212 is provided on the outer side of the connecting seat 21.

[0032] See also Figure 5-6 In order to fix the crossbar 3, a first insertion slot 22 is provided at the top of the column 2, and locking slots 221 are provided on both sides of the bottom of the first insertion slot 22. At the same time, a locking plate 32 is fixedly connected to the bottom of the crossbar 3 in a mirror image, and a protrusion 321 is fixedly connected to the outer side of the bottom of the locking plate 32, which can be inserted into the locking slot 221, thereby stably connecting the column 2 and the crossbar 3.

The outer side of the threading ring 4 is fixedly connected with a plug-in column 41, which is inserted into the second plug-in slot 31 to stably connect the cross bar 3 and the threading ring 4. At the same time, the outer side of the plug-in column 41 is also fixedly connected with a baffle 411 to prevent the wire coil from slipping out during the rotation process.

[0034] See also Figure 2 In order to increase the stability of the bottom plate 11, a fixing hole 111 is formed through the upper end surface of the bottom plate 11. The fixing holes 111 are evenly spaced around the central axis of the bottom plate 11. The entire two-for-one twisting mechanism can be fixed on the workbench through the fixing holes 111.

[0035] The working principle of the utility model is:

[0036] First, step 1: two wire coils are respectively sleeved on the first positioning ring 12 and the second positioning ring 13 with anti-slip function, thereby providing a stable wire coil placement environment.

[0037] Next, step 2: screw the connection seat 21 provided at the bottom of the column 2 onto the threaded column 141 on the output end of the motor 14 , so that the column 2 can rotate under the drive of the motor 14 .

[0038] Then, step 3: insert the locking plate 32 set at the bottom of the cross bar 3 into the first plug-in slot 22 opened at the top of the column 2. At this time, the protrusion 321 on the bottom outer side of the locking plate 32 will be stuck in the locking slot 221, thereby realizing a stable connection between the cross bar 3 and the column 2.

[0039] Then, step 4: insert the plug-in posts 41 fixedly connected to the outside of the threading ring 4 into the second plug-in slots 31 opened at both ends of the cross bar 3, so as to install the threading ring 4 to both ends of the cross bar 3.

[0040] Finally, step 5: pass the wire harness on the wire coil through the threading ring 4. Driven by the motor 14, the motor 14 will drive the column 2 to rotate, and the column 2 will drive the cross bar 3 to rotate, thereby twisting the wire harness into a strand.

[0041] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
