Technical Field

[0001] The utility model belongs to the field of extruder equipment, in particular to a rubber extruder. Background Art

[0002] An extruder, also known as an extruder, is mainly used for cable production. The cable production process is roughly as follows: first, the copper wire comes out of the pay-off rack and passes through the main machine head. The heated rubber can be extruded into the main machine head by the extruder and wrapped around the copper wire. After the main machine coats the copper wire with rubber, a cable can be formed. Finally, the take-up machine reels the cable.

[0003] For existing extruders, the heated rubber compound tends to solidify in the hopper, and the rubber compound tends to be unevenly mixed, affecting product quality. Utility Model Content

[0033] like Figures 1 to 4 As shown, the utility model discloses a rubber extruder, which includes a frame 100, a hopper 200, a discharge pipe 300, a screw rod 400, and a stirring element 500.

[0034] The hopper 200 is provided on the frame 100 and is used to receive the fluid rubber material. The hopper 200 has a feed port 210 and a discharge port 220. The discharge pipe 300 is provided on the frame 100. The discharge pipe 300 is provided with a discharge channel 310. The discharge pipe 300 is provided with a feed port 320 and a discharge port 330. The feed port 320 is connected to the discharge channel 310 and the discharge port 220 at the same time. The screw rod 400 is provided in the discharge channel 310 of the discharge pipe 300 in the vertical direction. The screw rod 400 can be The screw 400 rotates around its own axis, and a spiral channel 410 is formed between the screw rod 400 and the inner wall of the discharge channel 310. The fluid rubber in the hopper 200 can flow through the spiral channel 410 and finally flow out from the discharge port 330. The stirring member 500 is set on the frame 100. One end of the stirring member 500 is hinged to the frame 100, and the other end extends into the hopper 200 through the feed port 210. When one end of the stirring member 500 swings relative to the frame 100, the other end of the stirring member 500 swings in the hopper 200.

[0035] It is understood that during processing, the fluid rubber material can be poured into the hopper 200 through the feed port 210, and the fluid rubber material can enter the feed port 320 on the discharge pipe 300 through the discharge port 220, and then flow into the discharge channel 310 through the feed port 320. The screw rod 400 in the discharge channel 310 can transport the fluid rubber material toward the discharge port 330 during rotation until the fluid rubber material is discharged from the discharge port 330. During the above-mentioned extrusion process of the fluid rubber material, the stirring member 500 can swing relative to the frame 100 so that the end of the stirring member 500 extending into the hopper 200 can swing within the hopper 200, thereby stirring the fluid rubber material in the hopper 200, effectively ensuring the uniformity of the fluid rubber material in the hopper 200 and preventing the fluid rubber material from solidifying within the hopper 200.

[0036] The fluid refers to a liquid substance that can flow, including a flowable liquid substance with a certain viscosity. The aforementioned fluid adhesive can be a fluid plastic. By extruding the fluid plastic to the end of the main body 700, a cable sheath can be formed and a two-color wrapping of the cable can be achieved.

[0037] Reference Figures 2 to 4 In some embodiments of the present invention, the stirring element 500 includes a swing arm 510 and a stirring rod 520. The swing arm 510 has a first end 511 and a second end 512. The stirring rod 520 has a connecting end 521 and a stirring end 522. The middle portion of the swing arm 510 is hinged to the frame 100. The first end 511 of the swing arm 510 and the connecting end 521 of the stirring rod 520 are interconnected. The stirring end 522 of the stirring rod 520 extends into the hopper 200. By providing the swing arm 510 and the stirring rod 520, the stirring element 500 as a whole can be hinged to the frame 100 while also extending into the hopper 200 for stirring, and the space occupied by the stirring rod 520 can be reduced. The swing arm 510 and the stirring rod 520 can be integrated or separated.

[0038] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the stirring rod 520 is bent toward the discharge port 220 near the stirring end 522 to form a bending angle 530. By setting the bending angle 530, the shape of the stirring rod 520 at the stirring end 522 can be more consistent with the internal extension direction of the hopper 200, and the stirring rod 520 can be prevented from swinging at an excessive angle and colliding with the inner wall of the hopper 200. In some embodiments of the present invention, the bending angle 530 can be set to 120°.

[0039] like Figures 2 to 4As shown, in some embodiments of the present invention, a cam 600 is provided on the frame 100. The axis of the cam 600 is arranged in the vertical direction. The cam 600 can rotate horizontally around its own axis. The upper surface of the cam 600 has a protrusion 610. The thickness of the cam 600 at the location of the protrusion 610 is greater than the thickness of the cam 600 at other locations. The second end 512 of the swing arm 510 is in contact with the upper surface of the cam 600. Through the rotation of the cam 600, the second end 512 of the swing arm 510 can intermittently contact the area where the protrusion 610 and the non-protrusion 610 are located. When the swing arm 510 contacts the protrusion 610, the thickness of the protrusion 610 is inconsistent with the thickness of other areas. Therefore, the second end 512 of the swing arm 510 floats up and down, thereby achieving the swing of the swing arm 510.

[0040] Furthermore, if Figures 2 to 4 As shown, in some embodiments of the present invention, the rocker 510 is provided with a roller 540 at the second end 512. The roller 540 is coaxially arranged with the rocker 510 and can rotate relative to the rocker 510. The provision of the roller 540 enables the rocker 510 to achieve rolling contact with the upper surface of the cam 600, thereby reducing the friction between the rocker 510 and the cam 600. In some embodiments of the present invention, the cam 600 may have one or two protrusions 610. When two protrusions 610 are provided, the rocker 510 can swing faster.

[0041] In some embodiments of the present invention, the cam 600 can be designed to be coaxially arranged with the screw rod 400 and rotate synchronously. When the screw rod 400 rotates to perform the extrusion action, the cam 600 can rotate synchronously and drive the stirring element 500 to perform the stirring action. The extrusion and stirring actions can be performed simultaneously through the same power source, which saves costs and is easy to operate.

[0042] like Figures 2 to 4 As shown, in some embodiments of the present invention, there is an angle 550 between the stirring rod 520 and the rocker arm 510, and the angle 550 is adjustable. By adjusting the angle, the stirring member 500 can be adapted to stir hoppers 200 of different sizes and shapes.

[0043] like Figures 2 to 4 As shown, in some embodiments of the present invention, a cover 230 is provided above the hopper 200, and the cover 230 is flipped and connected to the hopper 200, and the cover 230 is used to cover the feed port 210. The cover 230 can be provided with a slot or opening to avoid the stirring member 500.

[0044] The above description further details the present invention in conjunction with specific preferred embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. A person skilled in the art of the present invention will appreciate that its architecture is flexible and adaptable, allowing for the development of a series of products without departing from the present invention's concept. Simple deductions or substitutions should be considered within the scope of patent protection for the present invention as defined by the submitted claims.
