DETAILED DESCRIPTION

[0026] The technical solution of the utility model is further described in detail below in conjunction with specific implementation methods.

[0027] The improvements made in the present utility model are based on the invention application previously submitted by the applicant, the invention name is “A wire twisting device”, the publication number is “CN113130132A”, and the publication date is “July 16, 2021”. Specifically, the specific structure of the wire twisting belt device 1, the frame 2, the clamping channel, the first wire twisting belt mechanism 11 and the second wire twisting belt mechanism 12 included in the wire twisting device is the same as that in the present utility model. The completeness of all technical features of the wire twisting belt device 1 will not be repeated in the following text. If there are technical features that need to be explained, please refer to the relevant technical features in the publication number “CN113130132A”.

[0028] like Figure 1 As shown, a wire twisting device comprises: a wire twisting belt device 1 and a frame 2; wherein the wire twisting belt device 1 is arranged on the frame 2 surface of the frame 2; the wire twisting belt device 1 comprises a clamping channel for the cable to pass through; the clamping channel can rotate along the direction of the cable travel; the wire twisting belt device 1 comprises: a first wire twisting belt mechanism 11 and a second wire twisting belt mechanism 12; wherein the first wire twisting belt mechanism 11 and the second wire twisting belt mechanism 12 rotate along the direction of the cable travel respectively; ... The clamping channel is formed in such a way that the working surfaces face each other; the first thread twisting belt mechanism 11 and the second thread twisting belt mechanism 12 are respectively connected to the thread twisting belt angle adjustment mechanism 3 arranged inside the frame 2 to adjust the angle between themselves and the surface of the frame 2; a position display device 4 is also provided above the frame 2, and the position display device 4 is connected to one side of the thread twisting belt device 1, and displays the angle between the first thread twisting belt mechanism 11 and the second thread twisting belt mechanism 12 relative to the upper plane of the frame 2 through the transmission of mechanical force. In this embodiment, the thread twisting belt device 1 adopts the first thread twisting belt mechanism 11 and the second thread twisting belt mechanism 12 which are arranged symmetrically on the left and right, and the thread twisting belt mechanism also includes: a combination of parts such as a bracket, a large pulley, a thread twisting belt, a side plate, a small shaft, a spring and a small pulley.

[0029] In order to control the diameter accuracy and cylindricity of cable products to be more uniform, the wire twisting belt angle adjustment mechanism 3 adjusts the wire twisting angles of different cables according to production requirements, so as to improve the control of wire twisting accuracy; and the position display device 4 is arranged on the front of the wire twisting belt device 1. Compared with the position display device 4 used in the prior art, it is easier to install and the data observation is more intuitive. It does not require the use of complex instruments such as electronic instruments to realize real-time display of the changing angle of the wire twisting belt mechanism.

[0030] like Figure 2As shown, further, the position display device 4 includes a linkage rod 41, a linkage bracket 42, a bracket fixing device 43, a pointer 44 and a scale plate 45; one side of the linkage rod 41 is fixedly connected to the upper surface of the thread-rubbing belt device 1, and the other side is connected to the linkage bracket 42; the linkage bracket 42 is "L"-shaped, one section is connected to the linkage bracket 42, and is parallel to the length direction of the thread-rubbing belt device 1; the other vertical section is connected to the bracket fixing device 43; the end side of the other section is connected to the pointer 44; the pointer 44 is provided with the scale plate 45 matched therewith, and the pointer 44 points to different scale marks on the scale plate 45 through movement. In this embodiment, the position display device 4 corresponds to the first thread-rubbing belt mechanism 11 and the second thread-rubbing belt mechanism 12, and two symmetrically arranged display devices are used to match the thread-rubbing belt mechanism to better reflect the position change of the thread-rubbing belt device 1. The position display device 4 in this embodiment mainly adopts a linkage mechanism (including a linkage rod 41, an L-shaped linkage bracket 42 and a bracket fixing device 43) to produce a linkage effect on the angle change of the pointer part 44, the scale plate 45 and the thread-rubbing belt mechanism. Through the transmission of force, the pointer part 44 moves up and down on the corresponding scale plate 45 and indicates the specific angle change value, so as to improve the angle control accuracy of the thread-rubbing belt.

[0031] Furthermore, the part where the linkage bracket 42 is connected to the linkage rod 41 is provided with a sliding groove 421, and the connection side of the linkage rod 41 can slide in the sliding groove 421. In this embodiment, one end of the linkage rod 41 is fixed on the thread twisting belt. In this embodiment, a tensioning mechanism is provided on the first thread twisting belt mechanism 11 and the second thread twisting belt mechanism 12. One end of the linkage rod 41 is provided with a screw and is fixedly connected to the upper part of the tensioning mechanism; through the working principle of the sliding groove mechanism, along with the change of the angle of the thread twisting belt, the linkage rod 41 is driven to perform linear movement in the sliding groove 421 to realize the real-time display of the position. The sliding groove is the key to realize mechanical linkage, which makes the structure of the position display device 4 simple, the production cost low, and easy to match with the thread twisting belt device 1.

[0032] Furthermore, the bracket fixing device 43 includes a U-shaped frame 431, a straight sliding shaft 432 and a slider 433. The straight sliding shaft 432 is arranged between the U-shaped frames 431. The slider 433 is sleeved on the straight sliding shaft 432 and can slide along the axial direction of the straight sliding shaft 432. In this embodiment, the bracket fixing device 43 is a three-sided panel. The open side is fixed by the straight sliding shaft 432 against the upper and lower surfaces. The straight sliding shaft 432 is provided with a matching slider 433, which can make the slider 433 slide up and down along the axial direction of the straight sliding shaft 432. Through the linkage bracket 42 with the linkage rod 41 and the sliding groove 421, the straight sliding shaft 432 and the slider 433 form a fixed slide rail, which simply utilizes the working principle of the straight sliding shaft 432, and drives the pointer to point by utilizing the up and down linear motion of the straight sliding shaft 432 through the functions of transmitting motion and bearing torque.

[0033] like Figure 4 As shown, further, the linkage rod 41 includes an "L"-shaped connecting portion 411 and a sliding portion 412, the horizontal section of the connecting portion 411 is connected to the top of the thread twisting belt mechanism, the vertical section of the connecting portion 411 is connected to one side of the sliding portion 412, and the other side of the sliding portion 412 matches the sliding groove 421, and the entire linkage rod is similar to a "Z" shape. In this embodiment, the thread twisting belt device 1 is higher than the frame 2 and has a certain height. In order to avoid interference with the thread twisting mechanism and better transmit the force, the linkage rod 41 needs to lift the connecting section to a certain height, fixedly connected to the thread twisting belt mechanism, and ensure that the other section interacts with the lower position of the sliding groove. The linkage rod 41 composed of two parts solves this problem well and better realizes the linkage effect of the sliding groove 421.

[0034] like Figure 5 As shown, further, the pointer member 44 is L-shaped and folded outward, and its pointer part and the scale plate 45 are arranged on the rear side of the bracket fixing device 43. In this embodiment, in terms of monitoring, the cable twisting position is displayed by the pointer pointing to the scale value of the ruler fixed on the outer frame. The sliding rod performs linear motion in the slide groove, driving the straight sliding shaft 432 to move up and down on the slide rail, so that the pointer can accurately point to the specific value on the scale plate 45, making the display of the cable twisting position more intuitive and clear. In terms of installation, the simple structure allows the operator to reasonably arrange the specific installation position of the position display device 4 according to production needs, making the adjustment of its installation position more convenient and quick, and can meet the needs of different production scenarios.

[0035] like Figure 3As shown, further, a quadrilateral protection frame 5 is provided on the outside of the frame 2, the bracket fixing device 43 is fixed on the inside of the protection frame 5, and the scale plate 45 is fixed on the outside of the protection frame 5. In this embodiment, a guide roller structure 6 is also provided in the middle of the protection frame 5, and the scale plate 45 is fixed between the entrance of the guide roller structure 6 and the outside of the protection frame 5, and the entrance of the guide roller structure 6 makes the display content of the scale plate 45 more obvious.

[0036] In summary, this position display device 4 can monitor the position of the wire twisting belt in the wire twisting device in real time, and judge the specific position of the wire twisting belt through the display position pointed by the scale pointer, so as to ensure a good wire twisting effect and effectively tighten the cable. During the wire twisting process, the core cable and the insulation layer in the cable are maintained in continuous and stable operation, and the core cable is prompted to rotate slowly, so as to achieve the purpose of uniform insulation coating and better improve the quality of the cable.

[0037] The position display device 4 has a simple structure and is easy to install, which can reduce the difficulty of production line transformation. It is also reliable in function and has an ideal use effect. It can monitor the cable twisting position in real time, which is convenient for operators to understand the cable twisting situation in real time to improve the twisting accuracy. While ensuring the quality of cable products, it reduces production costs and has high economic value.
