DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0037] Example:

[0038] Reference Figure 1-5 , an overmolding device for processing cables and cable cores, comprising an extrusion structure 100 including an extrusion housing 101;

[0039] The trigger sensing structure 200 includes three mounting bases 201 fixed to one end of the extruded housing 101, support rods 202 fixed to the surfaces of the three mounting bases 201, guide grooves 203 defined in the surfaces of the support rods 202, guide rods 204 slidably connected to the surfaces of the guide grooves 203, fan-shaped petals 206 fixed to one end of the guide rods 204, and a trigger sensing assembly 207 fixed to the other end of the guide rods 204.

[0040] The extrusion adjustment structure 300 includes a fixing ring 301 fixed to one end of the support rod 202 and located on the side of the trigger sensor assembly 207, a support ring 302 fixed to the surface of the fixing ring 301, three guide rails 303 fixed to the surface of the support ring 302, a first groove 304 defined in the surface of the guide rail 303, a second groove 305 defined in the surface of the first groove 304, an L-shaped connecting rod 306 that slides in the first groove 304, an adjustment assembly 308 fixed to one end of the L-shaped connecting rod 306, and a squeezing assembly 309 fixed to the other end of the L-shaped connecting rod 306. By providing a first spring 205 between the fan-shaped petals 206 and the support rod 202, the petals can automatically conform to cables of different diameters using elastic restoring force, while also buffering external impact forces and maintaining structural stability.

[0041] Among them, a first spring 205 is fixedly connected between the fan-shaped petal 206 and the surface of the support rod 202, the first spring 205 is arranged on the surface of the guide rod 204, the surface of the L-shaped connecting rod 306 is fixedly connected to the limit block 307, and the limit block 307 is slidably connected to the surface of the second groove 305; the first spring 205 has a reset function, and the elastic force of the first spring 205 is less than the outward expansion force generated by the outward expansion of the fan-shaped petal 206.

[0042] The support rod 202 has a receiving groove 219 on its surface, to which a gravity sensor 220 is fixedly connected. The fan-shaped flaps 206 and the first spring 205 allow the fan-shaped flaps 206 to fit tightly against the cable surface. The stopper 307 cooperates with the second groove 305 to ensure stable sliding of the L-shaped connecting rod 306. The gravity ball 216 and gravity sensor 220 detect the cable diameter, enhancing the device's adaptability and measurement accuracy.

[0043] The trigger sensing assembly 207 includes a push block 218 fixedly connected to the surface of the guide rod 204, two fixed plates 208 fixedly connected to the surface of the support rod 202 and located on either side of the push block 218, an adjustment bolt 209 rotatably connected to the surfaces of the two fixed plates 208, and an adjustment box 210 rotatably connected to one end of the adjustment bolt 209. By providing the trigger sensing assembly 207, changes in cable diameter are converted into mechanical displacement signals. The adjustment bolt 209 can be used to adapt the sensing requirements of cables of different diameters, thereby improving the reliability and accuracy of signal transmission.

[0044] The surface of the regulating box 210 is provided with roller holes 211. The roller holes 211 are arranged in a vertical linear array at equal intervals on the surface of the regulating box 210. One end of the roller holes 211 is chamfered. A fixed shaft 212 is fixedly connected to the surface of the roller holes 211. A clamping sleeve 213 is rotatably connected to the surface of the fixed shaft 212. The axis of the fixed shaft 212 is located on the central axis of the roller holes 211. By arranging the roller holes 211, the fixed shaft 212, and the clamping sleeve 213 on the surface of the regulating box 210, the linear motion of the push block 218 is converted into the circular motion of the clamping sleeve 213, reducing friction and making the motion conversion smoother.

[0045] The ferrule 213 is semi-enclosed, with one end of the ferrule 213 fixedly connected to a connecting plate 214. One end of the connecting plate 214 extends outside the roller hole 211. A gravity ball 216 is magnetically attracted to one end of the connecting plate 214. The surface of the gravity ball 216 is embedded in the surface of the connecting plate 214, and the diameter of the gravity ball 216 is smaller than the aperture of the roller hole 211. By configuring the ferrule 213, connecting plate 214, and gravity ball 216, the combined effects of magnetic attraction and gravity enable quantitative detection of cable diameter, expanding the sensing range.

[0046] A pick-off block 215 is fixedly connected to the surface of the roller hole 211 and is located directly below one end of the connecting rod. A second spring 217 is fixedly connected between the connecting plate 214 and the roller hole 211. The pick-off block 215 and second spring 217 ensure that the gravity ball 216 accurately falls into the receiving slot 219 and triggers the gravity sensor 220, which cushions the relative movement between the connecting plate 214 and the roller hole 211 and prevents component damage. The second spring 217 also provides a reset function.

[0047] Reference Figures 1-9 Furthermore, adjustment assembly 308 includes a toothed plate 310 fixedly connected to one end of L-shaped connecting rod 306, a turbine 311 meshingly connected to the surface of toothed plate 310, a fixing bracket 312 fixedly connected to the surface of support ring 302, and a rotating shaft 313 rotatably connected to the surface of fixing bracket 312. Turbine 311 is fixedly connected to the surface of rotating shaft 313. By providing adjustment assembly 308, the movement of L-shaped connecting rod 306 can be converted into the rotational movement of turbine 311, achieving precise control of extrusion assembly 309 and improving the uniformity of cable insulation coating.

[0048] Furthermore, a worm 314 is meshedly connected to the surface of turbine 311, a drive shaft 315 is fixedly connected to the surface of worm 314, an electric motor 316 is fixedly connected to one end of drive shaft 315, a command operation module 317 is fixedly connected to one end of electric motor 316, and a positioning sleeve 318 is movably connected to the surface of electric motor 316. The provision of worm 314, electric motor 316, and command operation module 317 enables remote operation and automated control, improving production efficiency and control accuracy.

[0049] Furthermore, the extrusion assembly 309 includes a support shell 319 fixedly connected to one end of the L-shaped connecting rod 306, a support shaft 320 fixedly connected to the surface of the support shell 319, a partition 321 fixedly connected to the center of the support shaft 320, two extrusion half-wheels 322 rotatably connected to the surface of the support shaft 320 and symmetrical about the partition 321, and a third spring 323 fixedly connected between the extrusion half-wheels 322 and the support shell 319. The provision of the extrusion assembly 309 enables uniform extrusion of the cable, ensuring a uniform thickness of the insulation layer and improving the cable sheathing quality. The third spring 323 provides a reset function.

[0050] Furthermore, an extrusion head 102 is fixedly connected to one end of the extrusion housing 101, and an extrusion hole 103 is formed on the surface of the extrusion head 102. By providing the extrusion head 102 and the extrusion hole 103, the initial covering of the cable can be achieved, providing a basis for subsequent extrusion and adjustment. The working principle of this part is prior art and is clearly understood by those skilled in the art, so it will not be elaborated here.

[0051] Specifically, when the cable and cable core processing coating molding device is working: first, the cable or cable core is coated by extrusion. During the coating process, the cable or cable core will pass through the extrusion hole 103 on the co-extrusion extrusion head 102. The insulation layer coming out of the extrusion hole 103 is solidified and formed after the temperature drops suddenly. It has a certain toughness and is in a state of not being completely dried. The cable or cable core wrapped with the insulation layer will pass through the fan-shaped petals 206. The support rods 202 are arranged on the mounting base 201 at equal intervals on the circumference to form a stable isosceles triangle. shaped structure, the cable passing through the fan-shaped petals 206 reduces the possibility of excessive roundness tolerance of the cable insulation layer after solidification. At this time, the three fan-shaped petals 206 will be squeezed and expanded, and the fan-shaped petals 206 will drive the guide rod 204 to slide in the guide groove 203. The push plate on the surface of the guide rod 204 is located on the side of the lowest rolling hole 211 on the surface of the adjustment box 210, and the push block 218 is located below the connecting plate 214. When the guide rod 204 moves, the push block 218 will push the connecting rod to drive the sleeve 213 to make a circular motion on the surface of the fixed shaft 212 , the ferrule 213 adopts a semi-closed state, which reduces the friction between the ferrule 213 and the fixed shaft 212, increases the ease with which the push block 218 pushes the connecting plate 214 to drive the ferrule 213 to rotate, and improves the uniformity of the distribution of the uncured insulation layer on the cable surface on the cable core or the cable surface. After the connecting plate 214 rotates, the gravity ball 216 magnetically attracted to the connecting plate 214 will be squeezed by the removal tip block 215, and the gravity ball 216 rolls from the rolling hole 211 into the receiving groove 219 and contacts the gravity sensor 220. The gravity sensor 220 is used to sense the single The weight of one or more gravity balls 216 transmits the sensed data to the instruction operation module 317. The number of gravity balls 216 rolling into the receiving groove 219 can reflect the size of the cable diameter. If multiple gravity balls 216 roll into the receiving groove 219, it means that the guide plate drives the push block 218 to act on more connecting plates 214, and the straightness of the cable is greater. If a single gravity ball rolls into the receiving groove 219, it means that the straightness of the cable is smaller. The design of the trigger sensing structure 200 avoids the defects caused by cold splicing and hot splicing, and can adapt to cables of different diameters.

[0052] Before the gravity sensor 220 senses the gravity of the gravity ball 216, the operator will conduct multiple sets of experiments to guide the distance the rod 204 moves to push the gravity ball 216 to fall into the receiving slot 219. The data sensed by the gravity sensor 220 corresponds to the cable size data. The instruction operation module 317 will control the number of revolutions of the electric motor 316 and the distance the gear plate 310 moves according to the numerical value of the experimental data. The working principle of this part is existing technology and can be clearly understood by those skilled in the art, so it will not be elaborated here.

[0053] The electric motor 316 controls the transmission shaft 315 to rotate, driving the worm 314 to rotate. The rotation of the worm 314 drives the rotation of the circular gear, and the circular gear drives the movement of the toothed plate 310. The movement of the toothed plate 310 controls the L-shaped connecting rod 306 to drive the expansion and contraction of the support shell 319. At this time, the cable will pass through the space formed by the three sets of extrusion half wheels 322, thereby increasing the fit of the insulation layer on the cable or cable core surface, and reducing the possibility of excessive coaxiality tolerance between the cable insulation layer and the conductor.

[0054] The cable or cable core is sheathed by extrusion. The fan-shaped flaps 206 and guide rods 204 allow the cable to be adjusted in real time according to its diameter as it passes through, reducing the roundness tolerance of the insulation layer. Simultaneously, the push block 218, ferrule 213, gravity ball 216, and gravity sensor 220 work together to detect and provide feedback on the cable diameter, avoiding the drawbacks of traditional cold and hot splicing and accommodating cables of varying diameters. Furthermore, the gravity sensor 220, in conjunction with the command operation module 317, coupled with the transmission of the electric motor 316, worm 314, and toothed plate 310, precisely controls the expansion and contraction of the extrusion half-wheel 322, increasing the fit of the insulation layer to the cable surface and reducing coaxiality tolerances. This significantly improves the quality of the cable sheathing and ensures the uniformity and reliability of the insulation performance.

[0055] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
