Description

Technical Field

[0001] The utility model belongs to the technical field of cable processing feeding devices, and specifically relates to a plastic particle supply device for cable processing. Background Technique

[0002] In the existing cable processing, the plastic particle supply device is a key device to ensure the stable supply of plastic raw materials to the extruder. With the development of industry, in order to better process plastic technology subsequently, operations such as drying and dispersing plastic particles are usually carried out during the supply process to ensure the quality of plastic particles entering the extruder.

[0003] Chinese Patent with application number CN202322791322.X discloses a plastic particle supply device for cable processing, including a supply device. A storage and impurity extraction box is slidably connected to one side of the supply device. A first motor is fixedly installed on one side of the storage and impurity extraction box.

Detailed implementation manners

[0029] Now, the present utility model will be further described in detail with reference to the accompanying drawings.

[0030] Please refer to Figures 1-6As shown in the figure, in this embodiment, a plastic particle supply device for wire and cable processing is provided, which includes a supply box 1. One side of the inner wall of the supply box 1 is rotatably fitted with a coarse screen 2. On one side of the inner wall of the supply box 1 and above the coarse screen 2, a discharge port 3 is provided. One side of the supply box 1 and below the discharge port 3 is fixedly connected with a crushing box 4. Inside the inner wall of the crushing box 4, two rotating shafts 5 are rotatably fitted. On both of the two rotating shafts 5, crushing rollers 6 are fixedly connected. On one side of the crushing box 4, a driving device 7 that cooperates with the two rotating shafts 5 is provided. On one side of the crushing box 4, a return material port 8 is provided, and the return material port 8 penetrates into the interior of the supply box 1;

[0031] On the inner wall of the supply box 1, an inclined fine screen 9 is fixedly connected. Below both the coarse screen 2 and the inclined fine screen 9, vibration motors 10 are fixedly connected. On the other side of the supply box 1, a discharge port 11 is provided. On the other side of the supply box 1, a supply component 12 located on one side of the discharge port 11 is fixedly connected. On the other side of the inner wall of the supply box 1, an adjustment component 13 that cooperates with the coarse screen 2 is provided. Both the coarse screen 2 and the inclined fine screen 9 are made of soft materials. When the vibration motors 10 vibrate themselves, the coarse screen 2 and the inclined fine screen 9 will vibrate themselves to screen the materials.

[0032] Please refer to Figure 2 , the driving device 7 includes an L-shaped block 701 fixedly connected to one side of the crushing box 4, a driving motor 702 fixedly connected to one side of the inner wall of the L-shaped block 701, two gears 703 fixedly connected to the two rotating shafts 5 and meshing with each other. The output end of the driving motor 702 is fixed to one end of one of the two rotating shafts 5. When the driving motor 702 on the L-shaped block 701 is started to drive one of the rotating shafts 5 to rotate, the other rotating shaft 5 can be driven to rotate in the reverse direction through the meshing of the gears 703, and then the crushing roller 6 can be driven to rotate and crush.

[0033] Please refer to Figure 3 , the supply component 12 includes a temporary storage box 121 fixedly connected to one side of the supply box 1, a conveying port 122 opened on the lower side of the inner wall of the temporary storage box 121, and a solenoid valve 123 fixedly connected to the inner wall of the conveying port 122. After being screened by the inclined fine screen 9, the materials roll down along the inclined fine screen 9 into the temporary storage box 121. By connecting the solenoid valve 123 with the feed port of an external extruder, feeding can be realized.

[0034] Please refer to Figure 4 and Figure 5, the adjustment component 13 includes an extension plate 131 fixedly connected to the other side of the inner wall of the supply box 1, an electric cylinder 132 fixedly connected to the upper side of the extension plate 131, a movable slot 133 opened on the lower side of the coarse screen 2, and a sliding block 134 slidably fitted on the inner wall of the movable slot 133 and rotatably fitted with the electric cylinder 132. When the electric cylinder 132 contracts, it pulls the coarse screen 2 to maintain balance. When it is necessary to pour out the particles accumulated on the coarse screen 2, the sliding block 134 is displaced in the movable slot 133 by pressing the electric cylinder 132, causing the coarse screen 2 to tilt at an angle, facilitating the rolling of over-sized particles.

[0035] Please refer to Figure 3 , a drying frame 14 is provided on one side of the supply box 1. A heating wire 15 is fixedly connected to the inner wall of the drying frame 14, and a plurality of fans 16 are fixedly connected to the inner wall of the drying frame 14 and on one side of the heating wire 15. The fans 16 can blow air into the supply box 1. After passing through the heating wire 15, the flowing air is heated, so that the hot air pre-dries the materials inside.

[0036] Please refer to Figure 3 , a hidden slot 17 is fixedly connected to the lower side of the inner wall of the discharge port 3. A magnetic attraction plate 18 is arranged on the inner wall of the hidden slot 17. When the materials after the first filtration flow out from the discharge port 3, the magnetic attraction plate 18 can adsorb and screen the possible metals in the flowing materials inside the hidden slot 17.

[0037] Please refer to Figure 1 , two guiding plates 19 are fixedly connected to the inner wall of the crushing box 4. A brush 20 in contact with the crushing roller 6 is arranged on the lower side of the guiding plates 19. When the larger materials fall from the discharge port 3, they fall on the upper sides of the two guiding plates 19 and are guided to the middle of the two crushing rollers 6. By contacting the brush 20 with the crushing roller 6, the materials adsorbed on the crushing roller 6 can be cleaned off.

[0038] The implementation principle of the plastic particle supply device for cable processing in an embodiment of the present application is as follows: When using this device, first place the supply box 1 stably in a suitable position. Pour the plastic particles to be supplied into the supply box 1 and above the coarse screen 2. Start the vibration motor 10 to vibrate the coarse screen 2 simultaneously, so that the smaller or qualified plastic particles are screened out and fall onto the inclined fine screen 9. By vibrating the inclined fine screen 9, the dust on the materials is separated and enters the temporary storage box 121 from the discharge port 11. It can be connected to the corresponding equipment through the solenoid valve 123 for feeding;

[0039] After screening, the oversized materials will remain on the coarse screen 2 and are pushed upward by the electric cylinder 132. The sliding block 134 slides in the movable groove 133, so that the coarse screen 2 can be adjusted to be inclined. The oversized plastic particles fall from the discharge port 3 along the coarse screen 2 into the crushing box 4. By starting the driving motor 702 to drive one of the rotating shafts 5 to rotate, the two rotating shafts 5 rotate in opposite directions through the gear 703, and then drive the crushing roller 6 to rotate to crush the dropped oversized particles a second time. The particles fall from the return port 8 onto the inclined fine screen 9, so as to ensure the uniformity of the size of the supplied material. Uniform particle size helps to ensure the stability of the extrusion process, thereby producing a uniform cable insulation layer and sheath and improving the overall quality of the finished cable.

[0040] The present utility model is not limited to the above embodiments. Anyone should know that structural changes made under the inspiration of the present utility model, as long as they have the same or similar technical solutions as the present utility model, all fall within the protection scope of the present utility model. The technologies, shapes, and structures not described in detail in the present utility model are all well-known technologies.
