Description

Technical Field

[0001] The utility model relates to the field of cabling machines, in particular to a cable breaking protection device for cabling machines. Background Art

[0002] At present, the cabling machine is a kind of wire and cable equipment used for cabling and armoring of multi-core rubber-sheathed cables, plastic power cables, cross-linked cables, telephone cables and control cables of various cross-sections. The armoring is a protective layer of steel wire weaved on the outside of the cable, which can enhance the overall strength of the cable. After the cabling machine forms the cable, it needs to be connected to the winding machine. The wire breakage is prone to occur during the winding process. The loss of pulling force after the wire breakage can easily cause cable blockage. For this purpose, the application number is: CN202122139615.0, which discloses a wire breakage protection device for a cabling machine for cable production, including a cabling machine, a mounting seat is fixedly installed at the bottom of the cabling machine, a support frame, a slide frame and a winding machine are fixedly installed on the top of the mounting seat, a slider seat is inlaid and installed inside the slide frame, a first limit wheel is fixedly installed on the surface of the slider seat, a contact switch is fixedly installed on the bottom of the inner wall of the slide frame, and a fixed frame is fixedly installed on the surface of the support frame. The utility model is connected with the cable output by the cabling machine through the limit wheel frame. When the wire of the winding machine is broken, the slider seat loses its supporting force and drops to trigger the contact switch, automatically turning on the alarm, the electric push rod and the servo motor. The alarm promptly warns the on-site staff of the broken wire and handles it in time. The servo motor can drive the limit wheel of the limit wheel frame to rotate, and the limit wheel frame cooperates with the second limit wheel to continue to ensure that the output of the cable is not interrupted, avoiding the shutdown of the production line due to the broken wire.

[0003] However, the above scheme still has certain defects. After research, it was found that in the above scheme, a limit wheel was installed on the slider seat to limit and guide the cable. When the cable was broken, the slider seat used gravity to slide downward to trigger the switch to start the protection mechanism to continue to guide and output the cable produced by the cabling machine to avoid cable blockage. Because the cabling machine is always outputting cables to one side of the winding machine, when the break point is located on the side of the slider seat close to the winding machine, the weight of the cable end close to the winding machine may balance the downward pressure of the slider seat, resulting in the slider seat being unable to slide downward to trigger the contact switch. In addition, the protection setting of continuing to guide the output of the cables may cause a large amount of cables to accumulate or even be thrown out, posing a danger to nearby workers.

[0004] How to invent a cable breaking protection device to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0005] In order to remedy the above deficiencies, the utility model provides a cable making machine wire breakage protection device, which aims to improve the existing technology by installing a limit wheel on the slider seat to limit and guide the cable. When the cable is broken, the slider seat slides downward using gravity to trigger the switch to start the protection mechanism to continue to guide and output the cable produced by the cable making machine to avoid cable blockage. Because the cable making machine is always outputting the cable to one side of the winding machine, when the breakage point is located on the side of the slider seat close to the winding machine, the weight of the cable close to the winding machine may balance the downward pressure of the slider seat, resulting in the slider seat being unable to slide downward to trigger the contact switch. In addition, the protection setting of continuing to guide the output of the cable may cause a large amount of cables to accumulate or even be thrown out, posing a danger to nearby workers.

[0006] The utility model is implemented as follows: a cable-making machine wire break protection device comprises a base, a rotary guide assembly is fixedly mounted on the top surface of the base, the rotary guide assembly comprises two relatively arranged mounting plates, turntables are rotatably mounted on the surfaces of opposite sides of the two mounting plates, two symmetrically arranged limiting rollers are rotatably mounted between the surfaces of opposite sides of the two turntables, trigger rods are fixedly mounted on both ends of the other side surface of each turntable, emergency stop switches are arranged on the surfaces of both sides of each mounting plate, and the two mounting plates are mounted on a lifting mechanism.

[0007] In a preferred technical solution of the utility model, two sliding holes are penetrated on the top surface of one of the mounting plates, and a sliding hole and a threaded hole are penetrated on the top surface of the other mounting plate, and the lifting mechanism includes three sliding rods and a threaded rod, each of the sliding rods is slidably connected to the corresponding sliding hole, and the threaded rod is threadedly connected to the threaded hole, one end of each of the sliding rods is fixedly connected to the upper surface of the base, and one end of the threaded rod is rotatably connected to the upper surface of the base.

[0008] In a preferred technical solution of the present utility model, a top plate is provided at the top end of each sliding rod.

[0009] In a preferred technical solution of the utility model, an annular groove is provided on the outer wall of each of the limiting rollers.

[0010] In a preferred technical solution of the present utility model, a protective rubber pad is arranged on the inner wall of each annular groove.

[0011] In a preferred technical solution of the utility model, a torsion spring mechanism is provided at the rotation connection between each of the turntables and the corresponding mounting plate.

[0012] The beneficial effect of the utility model is that the utility model obtains a cable-making machine wire breakage protection device through the above-mentioned design. When in use, the cable and the two limiting rollers generate an interaction force to limit the position. When the cable breaks, no matter which side the break point is located, the turntable will rotate due to inertia after losing the force applied by the cable, thereby contacting the emergency stop switch through the trigger rod to shut down the cable-making machine and the winding device. The cable-making machine will not continue to output cables after the breakage, causing accumulation that is difficult to sort out and causing danger to nearby personnel after being thrown out.

[0019] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figures 1 to 4The utility model provides a technical solution: a cable breaking protection device, comprising a base 1, a slewing guide assembly 2 is fixedly installed on the top surface of the base 1, the slewing guide assembly 2 comprises two relatively arranged mounting plates 201, a turntable 202 is rotatably installed on the surfaces of opposite sides of the two mounting plates 201, two symmetrically arranged limiting rollers 203 are rotatably installed between the surfaces of opposite sides of the two turntables 202, trigger rods 204 are fixedly installed at both ends of the other side surface of each turntable 202, emergency stop switches 205 are arranged on the surfaces of both sides of each mounting plate 201, and the two mounting plates 201 are installed on the lifting mechanism.

[0021] See also Figure 3 and Figure 4 Two sliding holes 206 are formed on the top surface of one mounting plate 201, and one sliding hole 206 and a threaded hole 207 are formed on the top surface of the other mounting plate 201. The lifting mechanism includes three sliding rods 208 and one threaded rod 209. Each sliding rod 208 is slidably connected to the corresponding sliding hole 206, and the threaded rod 209 is threadedly connected to the threaded hole 207. One end of each sliding rod 208 is fixedly connected to the upper surface of the base 1, and one end of the threaded rod 209 is rotatably connected to the upper surface of the base 1.

[0022] By rotating the threaded rod 209, the two mounting plates 201 can be driven to slide up and down on the corresponding sliding rods 208, thereby adjusting the height of the two limiting rollers 203, so that when the cable 3 passes through the two limiting rollers 203, the angles of the two bends are ensured to be greater than 90°, thereby preventing the cable 3 from being entangled and stuck on the two limiting rollers 203 after breaking, causing the turntable 202 to be unable to rotate and triggering the emergency stop switch 205, thereby improving the stability during use. At the same time, the overall height can be adjusted to adapt to more scenarios and reduce limitations in use.

[0023] Furthermore, a top plate 210 is disposed on the top of each sliding rod 208 .

[0024] By providing the top plate 210 , it is possible to avoid the two mounting plates 201 being disconnected from the corresponding sliding rods 208 due to operational errors when adjusting the heights of the two limiting rollers 203 , thereby improving stability and convenience during use.

[0025] Furthermore, an annular groove is formed on the outer wall of each limiting roller 203 .

[0026] The cable 3 can be limited by providing an annular groove on the outer wall of the limiting roller 203 to prevent the cable 3 from escaping from the guidance of the limiting roller 203 and reducing stability during use.

[0027] Furthermore, a protective rubber pad is provided on the inner wall of each annular groove.

[0028] The protective rubber pad can reduce the wear of the cable 3 when it is limited and guided by the limiting roller 203, thereby reducing the loss of the cable 3 during the production process. At the same time, it can also increase the friction between the cable 3 and the limiting roller 203, and better guide the winding of the cable 3 through the limiting roller 203.

[0029] Furthermore, a torsion spring mechanism is provided at the rotation connection between each turntable 202 and the corresponding mounting plate 201 .

[0030] The turntable 202 is rotatably connected to the corresponding mounting plate 201 via a rotating shaft. A torsion spring mechanism (not shown in the figure) is arranged on the rotating shaft to ensure that the rotation speed of the turntable 202 is accelerated after the cable 3 is broken, so that the trigger rod 204 can trigger the emergency stop switch 205 more quickly to shut down the cabling machine and the winding device, thereby avoiding the slow shutdown speed of the equipment causing the cabling machine to continue to work and causing a large amount of cable 3 to accumulate.

[0031] Working principle: First, install the device as a whole between the cabling machine and the winding device, and adjust the height of the two limit rollers 203 by rotating the threaded rod 209, connect the emergency stop switch 205 to the cabling machine, the winding device and the emergency stop line. When the cabling machine outputs the cable 3, one end of the cable 3 is passed from one side of one of the limit rollers 203 to between the two limit rollers 203, and is passed out from the other side of the other limit roller 203 to connect to the winding device. The two limit rollers 203 cause two bends in the cable 3 and are in a taut state, so that the limit rollers 203 and the cable 3 generate a force on each other and reach a balanced state. The cable 3 output by the cabling machine is wound through the winding device after passing through the conductors and limits of the two limit rollers 203. When the cable 3 is broken, the cable 3 stops bending the limit rollers 203. 03 applies a force, and the limiting roller 203 itself is affected by inertia to drive the turntable 202 to rotate. When the turntable 202 rotates, the trigger rod 204 on the surface of the other side will also perform a circular motion until it is released to the emergency stop switch 205 on the corresponding side. The cabling and winding devices can be shut down through the emergency stop switch 205, and the alarm device in the emergency stop line can be used to issue a shutdown alarm to the staff. The cable 3 and the two limiting rollers 203 are limited by the interaction force generated by the cable 3. When the cable 3 breaks, no matter which side the break point is located, the turntable 202 will rotate due to inertia after losing the force applied by the cable 3, thereby shutting down the cabling machine and the winding device through the trigger rod 204 contacting the emergency stop switch 205, and the cabling machine will not continue to output the cable 3 after the break, causing accumulation and making it difficult to sort.

[0032] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
