[0006] (II) Technical solution

[0007] To achieve the above objectives, the present invention is implemented by the following technical scheme: a method for preparing corrosion-resistant acid-alkali-resistant silicone rubber wire and cable, comprising the following steps:

[0008] Step 1: Mix the raw materials. Pour a variety of corrosion-resistant and acid-alkali-resistant injection molding materials into a mixing device, and then pour them into a stirring device for thorough mixing.

[0009] Step 2: Mixing: adding the mixed raw materials to a double-roll mill for mixing at 150° C. for 10 min, then adding additives, continuing to mix for 20 min, and then cooling at room temperature for finalization;

[0010] Step 3: extrusion granulation, the cooled mixed material is extruded into sheets using a tablet press, and then extruded into sheets using a twin-screw extruder;

[0011] Step 4: cable preparation: the twisted cable core is passed through a cable extrusion device, the mixed and re-extruded injection plastic is poured into the cable extrusion device, and the plastic material is extruded outside the cable core to form an insulation layer;

[0012] Step 5: Wind and store. Wind the formed cable after wrapping the insulation layer on the winding rack and then store it in the warehouse.

[0013] Preferably, the mixing device comprises a mixing box, a feeding funnel is symmetrically installed on one side of the mixing box, the feeding funnel is connected to the mixing box, an inclined plate is fixedly connected between the two sides of the inner wall of the mixing box, and a leakage groove is evenly opened on the top of the inclined plate, and a lifting block is slidably connected between the two sides of the inner wall of the leakage groove, and one end of the bottom of the lifting block extends to the outside of the leakage groove, and a grid plate is fixedly connected between the bottoms of the lifting blocks, and elastic rods are symmetrically installed at the bottom of the grid plate, and one end of the elastic rod away from the grid plate is fixedly connected to the inner wall of the mixing box, and support blocks are fixedly connected to the support blocks on both sides of the inner wall of the mixing box below the inclined plate, and a press switch is fixedly connected to the top of the support block, and electric-controlled telescopic rods are fixedly connected to the two sides of the mixing box through brackets, and the bottom of the electric-controlled telescopic rod is fixedly connected to a baffle, and the end of the baffle away from the electric-controlled telescopic rod extends to the interior of the mixing box and is slidably connected to the mixing box, Put two different corrosion-resistant acid-alkali injection molding materials into different feed Inside the funnel, the controller controls one of the electric-controlled telescopic rods to start, and after the electric-controlled telescopic rod pulls the baffle to rise, the injection plastic inside the feed funnel slides onto the inclined plate inside the mixing box. After a layer of injection plastic accumulates on the surface of the inclined plate, the overall mass above the inclined plate increases, and the lifting block is squeezed downward. The lifting block squeezes and bends the elastic rod downward until the lifting block is completely moved to the outside of the leakage trough, and the injection plastic above the inclined plate falls from the leakage trough to the bottom of the mixing box. After the injection plastic above the inclined plate falls, the elastic rod pushes the lifting block upward to the initial position, and the pressing switch is squeezed during the descent of the lifting block and the grid plate. The pressing switch transmits the signal to the controller and controls the high electric-controlled telescopic rod to descend. The electric-controlled telescopic rod pushes the baffle down and blocks the feed funnel. The controller controls another electric-controlled telescopic rod to drive the baffle to rise, and the injection plastic inside the other feed funnel slides into the mixing box, which can arrange different types of injection plastics in layers in order, and arrange different types of injection plastics evenly to facilitate subsequent sufficient and uniform mixing.

[0014] As the injection plastic above the inclined plate increases, it gradually squeezes the lifting block downward. When the mass of the injection plastic above the inclined plate reaches a certain limit, the lifting block as a whole drops to the outside of the leakage trough, and the injection plastic slides from the top of the inclined plate to the bottom of the mixing box. Changing the elastic coefficient of the elastic rod changes the mass of the material leaked from the inclined plate at one time, and can conveniently control the single-layer thickness of different types of injection plastics arranged in layers, thereby improving the flexibility of the device.

[0015] Preferably, one end of the support block passes through the mixing box and extends to the outside of the mixing box, and the end of the support block extending to the outside of the mixing box is fixedly connected to a controller, and the controller, the push switch and the electrically controlled telescopic rod are electrically connected.

[0016] Preferably, a receiving box is slidably connected to the inner bottom of the mixing box, one end of the receiving box away from the feeding funnel passes through the mixing box and extends to the outside of the mixing box, and one end of the receiving box extending to the outside of the mixing box is fixedly connected to a handle.

[0017] Preferably, the top of the feed funnel is open at one end close to the mixing box, and the top of the feed funnel is rotatably connected to one end close to the mixing box with a quantitative plate.

[0018] Preferably, a threaded rod is rotatably connected to one end of the inner bottom of the feed funnel near the mixing box, and a slide groove matched with the threaded rod is opened on the top of the quantitative plate. The slide groove penetrates the quantitative plate, and a support block is sleeved on the outside of the threaded rod below the quantitative plate. A handle is fixedly connected to one end of the top of the threaded rod. The threaded rod is rotated to rotate by rotating the handle. The support block drives the quantitative plate to rotate after the threaded rod rotates and rises, which can conveniently control the discharge speed of the feed funnel and improve the accuracy of the layered thickness of the injection molded product.

[0019] Preferably, a limiting groove is provided at the bottom of the quantitative plate, the inner top of the limiting groove is slidably connected to a limiting block, and the limiting block is rotatably connected to the supporting block.

[0020] Preferably, a lifting plate is fixedly connected to the bottom of the support block, and a discharge trough is symmetrically provided on one side of the lifting plate close to the mixing box. A swing plate is fixedly connected to one side of the inner wall of the discharge trough via a metal spring sheet. The threaded rod rotates the support block to rise, and the support block drives the lifting plate to rise at the same time. The lifting plate lifts part of the injection plastic at the discharge port of the feed funnel upward, and after a gap is generated at the discharge port, the injection plastic at a high place slides downward, impacting the injection plastic below to slide downward. When the discharge port of the feed funnel is blocked, it can be unblocked to avoid the feed funnel being unable to discharge material, thereby improving the reliability of the device.

[0021] As the support block rises, the injection plastic above the lifting plate squeezes the lifting plate downward, and the swing plate squeezes and bends the metal spring sheet downward, and the injection plastic above the lifting plate slides off the lifting plate. The metal spring sheet drives the swing plate to rotate to its initial position, and the injection plastic above the lifting plate can be discharged after the discharge funnel is unblocked, thereby reducing the waste of injection plastic.

[0022] (III) Beneficial effects

[0023] The present invention provides a method for preparing corrosion-resistant and acid-alkali-resistant silicone rubber wires and cables. It has the following beneficial effects:

[0024] (I) The method for preparing the corrosion-resistant acid-alkali-resistant silicone rubber wire and cable comprises the following steps: placing two different corrosion-resistant acid-alkali-resistant injection molding materials into different feed hoppers, and controlling one of the electric-controlled telescopic rods to start. After the electric-controlled telescopic rod pulls the baffle plate to rise, the injection molding materials inside the feed hopper slide onto the inclined plate inside the mixing box. After a layer of the injection molding materials accumulates on the surface of the inclined plate, the overall mass above the inclined plate increases, and the lifting block is squeezed downward. The lifting block squeezes and bends the elastic rod downward until the lifting block is completely moved to the outside of the leakage trough, and the injection molding materials above the inclined plate fall from the leakage trough to the mixing box. At the bottom of the material box, after the injection plastic above the inclined plate falls, the elastic rod pushes the lifting block upward to the initial position. During the descent of the lifting block and the grid plate, the press switch is squeezed. The press switch transmits the signal to the controller to control the electric telescopic rod at a high position to descend. The electric telescopic rod pushes the baffle down to block the feed funnel. The controller controls another electric telescopic rod to drive the baffle to rise, and the injection plastic inside the other feed funnel slides into the mixing box, which can arrange different types of injection plastics in layers in order. After the different types of injection plastics are evenly arranged, it is convenient for subsequent full and uniform mixing.

[0025] (ii) The method for preparing corrosion-resistant and acid-alkali-resistant silicone rubber wires and cables is as follows: the injection plastic above the inclined plate is increased and then gradually squeezed downwardly by the lifting block; when the mass of the injection plastic above the inclined plate reaches a certain limit, the lifting block as a whole drops to the outside of the leakage trough, and the injection plastic slides from the top of the inclined plate to the bottom of the mixing box; the mass of the material leaked from the inclined plate is changed by changing the elastic coefficient of the elastic rod, and the single-layer thickness of different types of injection plastics arranged in layers can be conveniently controlled, thereby improving the flexibility of the device.

[0026] (III) The method for preparing the corrosion-resistant and acid-alkali-resistant silicone rubber wire and cable drives the threaded rod to rotate by rotating the handle, and the support block drives the quantitative plate to rotate after the threaded rod rotates and rises and falls, which can conveniently control the discharge speed of the feed funnel and conveniently improve the accuracy of the layered thickness of the injection molding material.

[0027] (IV) The method for preparing corrosion-resistant and acid-alkali-resistant silicone rubber wires and cables comprises the following steps: the threaded rod is used to rotate the support block to raise the support block, and the support block drives the lifting plate to raise at the same time. The lifting plate lifts part of the injection plastic at the discharge port of the feed funnel upward, and a gap is generated at the discharge port, causing the injection plastic at a high position to slide downward, impacting the injection plastic below to slide downward, and being able to clear the discharge port of the feed funnel when it is blocked, thereby preventing the feed funnel from being unable to discharge materials, thereby improving the reliability of the device.

[0028] (V) The method for preparing corrosion-resistant and acid-alkali-resistant silicone rubber wires and cables is as follows: the lifting plate is raised as the support block, and the injection plastic above the lifting plate is pressed downward. The swing plate squeezes and bends the metal spring sheet downward, and the injection plastic above the lifting plate slides off from above the lifting plate. The metal spring sheet drives the swing plate to rotate to the initial position, and the injection plastic above the lifting plate can be discharged after the discharge funnel is unblocked, thereby reducing the waste of injection plastic.

[0029] (VI) The method for preparing corrosion-resistant and acid-alkali-resistant silicone rubber wires and cables improves the automation of the device by squeezing and pressing a switch to control the replacement of a discharging funnel for discharging after the lifting block is lowered, and can automatically complete the layering of a variety of injection molding materials.

After the electric-controlled telescopic rod 11 pulls the baffle 12 to rise, the injection plastic inside the feed hopper 2 slides onto the inclined plate 3 inside the mixing box 1. After a layer of injection plastic is accumulated on the surface of the inclined plate 3, the overall mass above the inclined plate 3 increases, and the lifting block 5 is squeezed downward. The lifting block 5 squeezes and bends the elastic rod 7 downward until the lifting block 5 is completely moved to the outside of the leakage trough 4, and the injection plastic above the inclined plate 3 falls from the leakage trough 4 to the bottom of the mixing box 1, and the injection plastic above the inclined plate 3 After the injection plastic falls, the elastic rod 7 pushes the lifting block 5 upward to the initial position.
