Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0026] A stranding mechanism of a composite cable stranding machine, such as Figure 1 As shown, it includes a capstan main shaft 1, and the end of the capstan main shaft 1 is detachably connected with a twisting tube 2. Specifically, the side of the capstan main shaft 1 is detachably connected to the twisting tube 2 by bolts; the side of the twisting tube 2 is provided with a branching guide wheel 6; the cable branch lines to be twisted enter the branching plate 3 through the branching guide wheel 6 on the twisting tube 2; it is ensured that the cables are not scratched and the entry angle is reliable. The side of the twisting tube 2 is provided with a connecting component 4, and the twisting tube 2 is detachably connected to the branching plate 3 through the connecting component 4;

[0027] The connecting assembly 4 includes a limit block 41, a moving rod 42, an extension rod 43 and a spring 44. Figure 2As shown, a spring 44 is provided inside the end of the twisted tube 2, and a moving rod 42 is connected to the end of the spring 44; a limiting block 41 is fixed to the side of the moving rod 42, and the limiting block 41 is slidably connected to the twisted tube 2; an extension rod 43 is fixed to the side of the moving rod 42, and the extension rod 43 is slidably connected to the twisted tube 2; the limiting block 41 is connected to the branching plate 3; specifically, the branching plate 3 includes an extension portion 31, a jack 32, a connecting portion 34, a through hole 35 and a limiting groove 36; as shown Figure 3 As shown, an extension portion 31 is provided on the outer side of the connecting portion 34, and the angle between the extension portion 31 and the connecting portion 34 is 45°-85°; a socket 32 ​​is provided in the center of the connecting portion 34, and the socket 32 ​​cooperates with the connection of the twisted tube 2; a limit groove 36 is provided on the side of the connecting portion 34, and the limit groove 36 cooperates with the connection limit block 41; a plurality of through holes 35 are provided on the surface of the extension portion 31; the through holes 35 are used to pass the cable branch lines that need to be twisted; when connecting the twisted tube 2 and the branch board 3, it is only necessary to extend the twisted tube 2 into the socket in the branch board 3 and insert it. When inserting, the limit block 41 is pressed into the inside of the twisted tube 2 until the limit block 41 reaches the limit groove 36. At this time, the limit block 41 enters the limit groove 36 under the push of the elastic force of the spring 44 to complete the connection between the twisted tube 2 and the branch board 3.

[0028] In order to strengthen the connection between the branching plate 3 and the twisted tube 2, the branching plate 3 further includes a threaded hole 33, which is opened on the inner wall of the insertion hole 32; the side of the twisted tube 2 is provided with thread teeth 21, which are matched and connected with the threaded hole 33. Therefore, the connection between the branching plate 3 and the twisted tube 2 is strengthened by using a threaded method.

[0029] In order to prevent the limit block 41 from falling out, the limit block 41 adopts a trapezoidal structure, and a moving rod 42 with a width greater than the limit block 41 is fixed to the bottom end of the limit block 41; a slide groove 22 is formed inside the twisted tube 2, and the moving rod 42 slides in the slide groove 22.

[0030] like Figure 4 and Figure 5As shown, in order to detect the disconnection of the twisted cable branch, a detection component 5 is provided in the through hole 35, and the detection component 5 includes a pressure block 51, a pressure sensitive element 52, a slide column 53 and an arc plate 54; the side of the through hole 35 is slidably connected with a slide column 53, and the top of the slide column 53 is provided with a pressure block 51; the bottom end of the slide column 53 is provided with an arc plate 54, and the arc plate 54 is in contact with the pressure sensitive element 52; the pressure sensitive element 52 is electrically connected to the alarm. The pressure block 51 adopts an arc structure, and the cross-section of the pressure block 51 is a "T"-shaped structure; the bottom end of the pressure block 51 is fixed with an arc plate 54 with a semicircular ring structure. When the cable branch is inserted into each through hole 35, since each cable branch needs to be twisted together later, there is a downward pressure on the through hole 35 when each cable branch passes through the through hole 35, and the pressure sensitive element 52 determines whether the cable branch is disconnected by sensing the existence of this force;

[0031] The principle of detecting pressure and alarming (pressure alarm) in the utility model is as follows: the pressure sensitive element is the core component of the pressure alarm, which is a pressure sensor or a pressure sensitive element. This element can sense the pressure changes in the surrounding environment and convert it into an electrical signal. Commonly used pressure sensitive elements include pressure transmitters and pressure sensors. Circuit control: The circuit control part in the pressure alarm is responsible for processing the electrical signal transmitted by the pressure sensitive element. Through a series of circuit designs and logical controls, the discrimination and processing of the pressure signal can be realized. For example, when the electrical signal exceeds the preset pressure threshold, the circuit will trigger the alarm operation. Alarm: Once the circuit control part detects a signal exceeding the preset pressure threshold, an alarm signal will be issued. The alarm device can be a sound alarm device that issues a striking sound reminder; it can also be a light source alarm device that issues a bright light source reminder; or it can also be a wireless signal alarm device that transmits the alarm signal to a remote monitoring center through wireless communication. The pressure alarm usually allows the user to set the pressure threshold according to actual needs. The user can adjust the trigger pressure of the device by means of knobs, buttons, etc. Once the pressure exceeds the threshold set by the user, the alarm device will trigger the alarm. In short, the pressure alarm senses pressure changes through pressure sensitive elements, and after circuit control and user-set operations, triggers the alarm device to send an alarm signal to remind the user that the pressure exceeds the safe range; the pressure alarm belongs to the content of the existing technology.

[0032] When the utility model is in use, the twisted tube 2 is first connected to the capstan main shaft 1 and the dividing plate 3. The capstan main shaft 1 and the twisted tube 2 are connected by bolts. The twisted tube 2 and the dividing plate 3 are connected in the following manner: the twisted tube 2 is aligned with the insertion hole 32, and the twisted tube 2 is inserted into the insertion hole 32 by rotation. When inserted, the limit block 41 is pressed into the inside of the twisted tube 2, and the threaded teeth 21 are threadedly connected with the threaded hole 33 by rotation until the limit block 41 reaches the limit groove 36. At this time, the limit block 41 is in Pushed by the elastic force of the spring 44, it enters the limit groove 36, completing the double fixed connection between the twisted tube 2 and the branching plate 3 through the thread and the cooperation between the limit block 41 and the limit groove 36; when in use, the cable branch passes through the branching guide wheel 6 and enters the perforation 35, and the cable branch exerts a downward force on the pressure block 51, and exerts pressure on the pressure sensitive element 52 through the sliding column 53 and the arc plate 54. Therefore, the pressure sensitive element 52 determines whether the cable branch is disconnected by sensing the pressure change, and an alarm is issued if it is disconnected.
