Description

Technical Field

[0001] The utility model relates to the technical field of extruders, in particular to an extruder feeding device used for cable processing. Background Art

[0002] When the extruder is performing extrusion operation, plastic particles need to be continuously fed into the extruder through the feed hopper at the upper end of the extruder. The feed hopper is usually made of materials such as plastic or stainless steel and has a certain capacity to ensure a stable supply of raw materials during continuous production.

[0003] When the feed hopper conveys the plastic pellets stored inside to the extruder, the plastic pellets may be squeezed in the feed hopper, which may cause blockage, thereby affecting the normal production of the extruder. Therefore, the Chinese utility model patent disclosed by the existing publication number CN216804347U: extruder feeding device, which drives the cover plate to intermittently cover the discharge port through the drive component. After the pellets are sent to the material holding chamber, they intermittently enter the discharge chamber from the discharge port. The pellets are less accumulated at the discharge port, which reduces the congestion of the pellets at the discharge port. The smoothness of extruder feeding is improved, and by opening a plurality of curved grooves with different contours on the driving wheel and cooperating with a push-pull rod with adjustable length, the extruder feeding device can adapt to the production workshop's needs for different flow rates of pellets. First, the application increases energy consumption by adding additional rotating power parts to control the rotation of the driving wheel and the auger. Secondly, the application controls the movement of the cover plate through the driving wheel and the push-pull rod, which will lead to indirect feeding into the guide cylinder, which may easily cause the raw material in the guide cylinder to be interrupted, thereby affecting the normal extrusion operation.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-Figure 6 As shown, the utility model provides an extruder feeding device for cable processing, comprising a first hopper body 1, a second hopper body 2, and a sleeve 3. A first fixed flange 4 is fixedly installed on the upper end of the first hopper body 1, and second fixed flanges 5 are fixedly installed on the upper and lower ends of the second hopper body 2, and one of the second fixed flanges 5 is fixedly connected to the first fixed flange 4. A third fixed flange 6 is fixedly installed on the lower end of the first hopper body 1, a guide cover 7 is fixedly installed at the lower position inside the first hopper body 1, the sleeve 3 is fixedly installed in the first hopper body 1, and a lifting rod 8 is movably installed in the sleeve 3, and an adjustment cover 9 is movably installed on the lower end of the lifting rod 8.

[0023] like Figure 2-Figure 4As shown, a connecting flange 10 is arranged on the outside of the sleeve 3, and a plurality of connecting frames 11 are fixedly connected between the sleeve 3 and the connecting flange 10. The connecting flange 10 is fixedly installed between the corresponding second fixing flange 5 and the first fixing flange 4, and the sleeve 3 is placed at the center position in the first hopper body 1 through the connecting flange 10 and the connecting frame 11. With the arrangement of the sleeve 3, it can be ensured that the lifting rod 8 can be stably lifted and lowered in the first hopper body 1. Three slide grooves 12 are arranged on the inside of the sleeve 3, and an adjusting ring 14 is arranged on the outside of the sleeve 3 at the position of the slide groove 12. Sealing covers 15 are fixedly installed on the upper and lower ends of the adjusting ring 14, and the adjusting ring 14 is threadedly connected to the outside of the sleeve 3 through two sealing covers 15. A rotating groove is also arranged on the inside of the adjusting ring 14.

[0024] like Figure 2-Figure 3 , Figure 5-Figure 6 As shown, the lifting rod 8 is inserted and installed in the casing 3, and the upper end and the lower end of the lifting rod 8 respectively pass through the upper end and the lower end of the casing 3 to extend to the outside of the casing 3, a lifting ring 16 is movably installed on the outside of the lifting rod 8, and a fixing ring 18 is fixedly installed on the lifting rod 8 located above the lifting ring 16, and a pressure block 13 is fixedly installed on the upper end of the lifting rod 8, and three sliders 17 are fixedly installed on the outside of the lifting ring 16. One end of the slider 17 passes through the corresponding slide groove 12 and extends to the rotating groove inside the first fixed flange 4. The lifting rod 8 between the lifting ring 16 and the fixing ring 18 is sleeved with a compression spring 19. The pressure of the compression spring 19 can be adjusted by controlling the adjusting ring 14 and the lifting ring 16, and then the pressure value of the pressure block 13 can be adjusted. A screw groove 20 is opened at the center position of the top of the adjusting cover 9, and the screw groove 20 is threadedly connected to the lower end of the lifting rod 8, and the adjusting cover 9 is placed in the lower position inside the guide cover 7. By adjusting the distance between the adjusting cover 9 and the guide cover 7, the material discharge space can be increased to prevent blockage.

[0025] It should be noted that the utility model is an extruder feeding device for cable processing. When the extruder 21 is in normal production, the material in the first hopper body 1 enters the extruder 21 through the guide cover 7. If the material in the first hopper body 1 is squeezed and blocked, the external conveying mechanism will continue to quantitatively convey the material to the first hopper body 1 and the second hopper body 2. When the material is accumulated in the second hopper body 2, the weight of the accumulated material is pressed on the pressure block 13. At the same time, the weight of the material in the first hopper body 1 is also pressed on the adjusting cover 9, thereby increasing the pressure on the pressure block 13 and the adjusting cover 9 to make the compression spring The spring 19 is compressed toward the lifting ring 16, so that the lifting rod 8 drives the adjusting cover 9 to move downward, thereby increasing the unloading space between the adjusting cover 9 and the guide cover 7. When the unloading space is increased, the material has more sufficient space to diffuse and flow during the flow process, and sufficient unloading space allows the material to flow more smoothly under the action of gravity. After the materials in the first hopper body 1 and the second hopper body 2 enter the extruder 21 normally, and the materials are no longer accumulated in the second hopper body 2 above the pressure block 13, the fixing ring 18 is pushed up by the force of the compression spring 19, thereby driving the lifting rod 8 to move upward, thereby causing the adjusting cover 9 to move upward in the guide cover 7 and restore the normal unloading feed rate.
