[0002] The stranding machine is one of the commonly used machines in cable production. It is mainly used to strand multiple cables into one strand. During the stranding process, safety protection is set at the entrance of the single-strand cable into the stranding machine to reduce the possibility of the stranding machine injuring the operator during the stranding process. Conventional safety protection generally sets a protective cage at the inlet of the stranding machine. The cable can only enter the stranding machine after passing through the protective cage, that is, the operator will not directly contact the stranding machine during operation, reducing the possibility of injury accidents.
[0003] During actual operation, it was found that there was no protection at the wire entrance of the protective cage and the size of the protective cage and the wire entrance of the stranding machine were almost the same. Therefore, when the cable continued to pass through the protective cage, there was still a safety risk in the gap between the protective cage and the cable, and the safety of the entire device was not high.

DETAILED DESCRIPTION
[0034] The following is combined with Figure 1-Figure 3 This application is described in further detail.
[0035] The embodiment of the present application discloses a wire twisting machine safety protection device. The device is installed on a wire twisting machine, which can be a commonly used mechanical device for twisting multiple cables into one cable, wherein the part for twisting multiple cables is referred to as a twisting assembly 2 in the present application, which is a conventional assembly, and the present application will not repeat its specific structure. In the present application, the device is installed outside the twisting assembly 2, so it can adapt to most conventional twisting assemblies 2. The twisting assembly 2 is installed on the base 1 for twisting single-strand cables. The wire twisting machine safety protection device is also installed on the base 1 and covers the outside of the twisting assembly 2.
[0036] Reference Figure 1 The safety protection device of the stranding machine at least includes an outer shield 3, which is installed on the base 1. The outer shield 3 includes a fixed shield 31 and a dynamic shield 32. The fixed shield 31 is fixed on the base 1 and placed on one side of the stranding assembly 2. The dynamic shield 32 is hinged on the fixed shield 31 and covers the top of the stranding assembly 2. When the dynamic shield 32 covers the stranding assembly 2, the side of the dynamic shield 32 away from the fixed shield 31 contacts the base 1 and is locked and fixed with the base 1 through the locking assembly 6. A support cover 34 is fixed on the side of the base 1 away from the fixed shield 31, and mounting holes are respectively provided on the support cover 34 and the dynamic shield 32 for installing the locking assembly 6. During the cable stranding process, the outer shield 3 is in a locked state, and the cable needs to pass through the protective cage 33 before entering the stranding assembly 2, so that the operator will not directly contact the stranding assembly 2 during actual operation, which is safer.
[0037] Reference Figure 1 and Figure 2The lock assembly 6 includes a longitudinal lock tongue 61 and a transverse lock tongue 62. The longitudinal lock tongue 61 is inserted into the mounting hole on the support cover 34. A longitudinal spring is sleeved on the longitudinal lock tongue 61. One end of the longitudinal spring is fixed on the longitudinal lock tongue 61, and the other end of the longitudinal spring is fixed in the mounting hole on the support cover 34. The transverse lock tongue 62 is inserted into the mounting hole on the dynamic shield 32. A transverse spring is sleeved on the transverse lock tongue 62. One end of the transverse spring is fixed on the transverse lock tongue 62, and the other end of the transverse spring is fixed in the mounting hole on the dynamic shield 32. A locking groove is provided on the side wall of the longitudinal lock tongue 61 for one end of the transverse lock tongue 62 to be inserted. The other end of the transverse lock tongue 62 passes through the dynamic shield 32, and a handle is provided on the other end of the transverse lock tongue 62. After the outer shield 3 is covered, the transverse lock tongue 62 and the longitudinal lock tongue 61 are mutually buckled to form a lock. When it is needed to be opened, the transverse lock tongue 62 can be pulled by the handle to disengage the transverse lock tongue 62 from the main lock tongue, so that the dynamic shield 32 can be conveniently opened. In addition, the locking assembly 6 is always in a locked state during the entire twisting process, and even if there is a slight shake, the protective cover 32 can still cover around the twisting assembly 2, thereby reducing the probability of accidents and improving safety.
[0038] Reference Figure 1 and Figure 3 There is another embodiment of the lock assembly 6. The lock assembly 6 only includes an elastic lock tongue 63. A mounting seat is correspondingly fixed on the support cover 34 for mounting the Taixing lock tongue. A hole is opened on the mounting seat. The elastic lock tongue 63 is inserted into the hole. The elastic lock tongue 63 needs to be higher than the mounting seat under normal conditions, and a gap is formed between the support cover 34. An elastic sheet 64 extends from the edge of the dynamic shield 32. After the dynamic shield 32 is closed, the elastic sheet 64 is directly inserted into the gap and the elastic sheet 64 abuts against the elastic lock tongue 63. In order to form a lock, a lock hole can also be opened on the elastic sheet 64, and the elastic lock tongue 63 is inserted into the lock hole. Under this scheme, a groove needs to be opened on the elastic lock tongue 63 to form a locking effect with the edge of the lock hole. Of course, the lock assembly 6 of this embodiment and the lock assembly 6 of another embodiment can be used at the same time to obtain a better locking effect.
[0039] Reference Figure 1 A protective cage 33 can also be fixed at the wire entry hole of the twisted wire assembly 2. The protective cage 33 is coaxial with the wire entry port of the twisted wire assembly. The cable passes through the outer shield 3 and the protective cage 33 in sequence to enter the twisted wire assembly. One end of the protective cage 33 is fixed on the twisted wire assembly and is wound around the wire entry hole of the twisted wire assembly. The other end of the protective cage 33 extends toward the wire entry port and is coaxial with the wire entry port. The cable needs to pass through the outer shield 3 and the protective cage 33 in sequence to enter the twisted wire assembly 2 and be twisted into a cable. During the entire twisting process, the twisted wire assembly 2 is relatively closed, and the operator cannot directly touch the twisted wire assembly 2 during operation, so it is safer.
[0040] Reference Figure 1A wire management ring 7 is provided on the base 1. Before the single-strand cable enters the twisted assembly 2, the wire management ring 7 is placed on one side of the wire inlet of the outer protective cover 3. A plurality of threading holes are provided on the wire management ring 7. The threading holes are evenly distributed on the end surface of the wire management ring 7. A strand of cable is passed through each threading hole. After the cable passes through the threading hole, it enters the protective cover so that the single-strand cable is straightened before entering the twisted assembly 2, so that it enters more smoothly.
[0041] Reference Figure 1 , a support rod 4 needs to be fixed on the corresponding base 1. The support rod 4 is L-shaped, so that the cross bar of the support rod 4 is placed horizontally above the twisting assembly 2. The sensor assembly 5 is fixed on the cross bar to monitor whether there is foreign matter intrusion into the outer shield 3. If there is, the twisting assembly 2 is stopped urgently, and the outer shield 3 cooperates to further reduce the probability of safety accidents. The sensor assembly 5 includes a sensor 51 and a controller 52. The sensor 51 is fixed on the support rod 4 and faces the outer shield 3. The sensor 51 signal is connected to the controller 52 to send a signal to the controller 52.
[0042] When the stranding machine of the present application is working, the outer shield 3 covers the stranding assembly 2. During the working process, the stranding assembly 2 is protected by the outer shield 3, so that the operator cannot directly contact the stranding assembly 2. At the same time, the wire inlet opening on the outer shield 3 is large, and the gap between the outer shield 3 and the stranding assembly 2 is large, so there is basically no squeezing, and the safety is good. At the same time, the sensor assembly 5 can detect the intrusion of foreign objects, and immediately shut down if there is intrusion of foreign objects, thereby improving safety.
[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
