Description

Technical Field

[0001] The utility model relates to the technical field of material recovery, and more specifically, to a production device for plastic particles of wires and cables. Background Art

[0002] The recycling process of PVC in waste cable materials is an environmentally friendly and economical method that aims to convert waste PVC cable materials into reusable resources. The main process is: first, classify and pre-treat the cable materials to remove impurities and non-PVC components; second, crush the PVC to obtain fine powder; third, separate the PVC fine powder from impurities through a screening mechanism; fourth, dry and granulate the separated PVC powder to make it into granules.

[0003] In the process of shredding PVC, in order to prevent the shredder from getting stuck due to the excessively fast feeding speed, a cable material conveying device is set in front of the shredder. Because the recycled cable material lines will be entangled with each other, it is necessary to manually remove the cable material from the material mass and then put it on the conveying device. However, the cable lines are long and short, and some of the recycled cable materials are seriously tangled, making it difficult to manually separate them in a short time, which greatly affects the feeding rate.

[0004] Therefore, in order to solve the above technical problems, the present application proposes a production equipment for plastic particles of wires and cables. Utility Model Content

[0040] like Figure 1-4 As shown, a wire and cable plastic particle production device includes a feeding mechanism 1 for cutting cables in layers for uniform feeding, and the feeding mechanism 1 includes a filler component 11, a fork wire component 12, a cutting component 13 and a crushing component 14;

[0041] The filling assembly 11 is arranged above the fork wire assembly 12, and is used to store the cables to be crushed and feed downwards. The crushing assembly 14 is arranged below the cutting assembly 13, and is used to receive and crush the cables cut by the cutting assembly 13;

[0042] The packing assembly 11 includes a packing bin 111, an upper cover 112, an electric lifting rod 113, a spring 114 and a lower pressing plate 115. The packing bin 111 is a container for storing cables. The packing bin 111 is a frame-shaped structure with openings at the top and bottom. The upper cover 112 is buckled on the upper part. The mounting end of the electric lifting rod 113 is mounted on the mounting surface of the upper cover 112. The lifting end of the electric lifting rod 113 is mounted on the surface of the lower pressing plate 115. The mounting surface of the upper cover 112 and the surface of the lower pressing plate 115 are also connected with a spring 114. The spring 114 is used to press the lower pressing plate 115 downward to compress the cables. The electric lifting rod 113 is used to supplement the downward pressure on the cables after exceeding the elastic potential energy range of the spring 114 to ensure continuous feeding.

[0043] In the initial state, the front end of the cutter 133 is attached to the inner wall of the second mounting frame 131, closing the lower opening of the filling bin 111, and the wire fork 123 completely withdraws from the falling range of the filling bin 111, and the recovered cable is put into the filling bin 111, and the upper cover 112 is buckled, and the electric lifting rod 113 remains in a completely recovered state. At this time, the lower pressing plate 115 is pushed by the elastic potential energy of the spring 114 itself, and the lower pressing plate 115 squeezes the cable, so that the cable distribution is relatively compact, which can save the storage space of the filling bin 111, and also avoid cutting empty when the cutter 133 is cutting;

[0044] When the cable is continuously discharged from the filling bin 111, the elastic potential energy of the spring 114 gradually weakens, and the extrusion capacity also weakens. At this time, the electric lifting rod 113 can be started to continue to press the lower pressure plate 115 downward to ensure continuous feeding. It should be noted that the elastic potential energy of the spring 114 is sufficient to push the electric lifting rod 113 to the longest position, so as to avoid the spring 114 being broken when the electric lifting rod 113 pushes the lower pressure plate 115. Alternatively, the spring 114 can be set to be sleeved on the surface of the electric lifting rod 113 to avoid this problem.

[0045] Therefore, by setting the filler assembly 11, the cable material can be pushed downward by the spring 114 and the electric lifting rod 113 to prevent the cable from falling naturally due to excessive friction between the cable and the filler bin 111, and to compact the cable, thereby avoiding the cutter 133 from cutting empty and improving the cutting and feeding rate;

[0046] The fork wire assembly 12 is used to plug the cable so that only a small part of the cable leaks out from under the fork wire assembly 12. The cutting assembly 13 is used to cut the cable leaking out of the fork wire assembly 12 and to hold the cable from below to prevent it from falling off directly when the fork wire assembly 12 is recovered.

[0047] The fork wire assembly 12 includes a first mounting frame 121, a first lead screw 122, a first motor 124 and a wire fork 123. The first mounting frame 121 has a side away from the horizontal ground as a supporting surface, and the other side as a continuous surface. The first lead screw 122 is installed in the mounting frame through a bearing. The first lead screw 122 is driven to rotate by the first motor 124. The first lead screw 122 is threadedly connected with a wire fork 123, and the wire fork 123 is used to insert and fix the cable.

[0048] The slitting assembly 13 includes a second mounting frame 131, a second lead screw 132, a second motor 134 and a cutter 133. The second mounting frame 131 has a side away from the horizontal ground as a supporting surface, and the other side as a continuous surface. The supporting surface of the second mounting frame 131 is arranged in close contact with the continuous surface of the first mounting frame 121, and a second lead screw 132 is installed in the mounting frame through a bearing. The second lead screw 132 is driven to rotate by the second motor 134. The second lead screw 132 is threadedly connected with a cutter 133, and the cutter 133 is used to cut the cable.

[0049] After the feeding is completed, the first motor 124 is driven, and the first lead screw 122 drives the wire fork 123 to move forward. The wire fork 123 will insert the cable from above the cutter 133. At this time, the second motor 134 is driven, and the second lead screw 132 drives the cutter 133 to be recovered. The cable loses the support of the cutter 133 and is fixed by the wire fork 123 and naturally hangs down under the influence of gravity. The second motor 134 is controlled to reverse, and the second lead screw 132 drives the cutter 133 to move forward. The cutter 133 cuts the cable hanging below the wire fork 123. The cutter 133 can be set as a rotatable saw blade with a diameter larger than the inner diameter of the filling bin 111 to ensure cutting efficiency.

[0050] Until the front end of the cutter 133 is attached to the inner wall of the second mounting frame 131, the cut cable falls into the crushing assembly 14, and the first cutting is completed. Then the wire fork 123 is retracted, and the cutter 133 and the wire fork 123 return to the initial state. The above steps are repeated again to continuously cut the cable in layers.

[0051] Therefore, by setting the fork wire assembly 12 and the cutting assembly 13, the wire fork 123 in the fork wire assembly 12 is driven by the lead screw to insert and fix a layer of cable wires from the bottom, and then the cutter 133 is pushed forward to cut off the leaked layer of cable wires. The cutter 133 forms a limit under the wire fork 123 to provide conditions for reinserting the cable after the wire plug is recovered. The wire fork 123 and the cutter 133 cooperate with each other in this way, and the accumulated cables in the filling bin 111 are cut off layer by layer to prevent them from falling into a ball and being stuck in the crushing assembly 14.

[0052] The crushing assembly 14 includes a crushing chamber 141 and a crushing roller 142. The crushing chamber 141 is also a frame structure with openings at the top and bottom and is received below the slitting assembly 13. The crushing roller 142 is installed in the crushing chamber 141 for crushing the cable. The surface of the crushing roller is provided with a blade. The rotation of the crushing roller drives the blade to crush the cable cut by the cutter 133.

[0053] The inner diameter of the stuffing bin 111 is smaller than the outer diameter of the cutter 133, so that after the wire fork 123 is withdrawn, the cutter 133 can block the unloading port of the stuffing bin 111 to prevent the whole ball of cables from falling;

[0054] The length of the first mounting frame 121 is greater than the length of the wire fork 123, and the length of the second mounting frame 131 is greater than the length of the cutter 133, so that the cutter 133 and the wire fork 123 can be completely withdrawn from the lower opening of the filling bin 111, and the positions are alternated to complete the cycle cutting;

[0055] A screening component 2 is provided below the crushing bin 141, which is used to separate the wire core from the cable sheath and transport the cable sheath forward. The screening component 2 uses vibration screening, and then separates the wire core from the cable sheath by blowing and gravity, and adds a magnetic suction component to absorb the iron wire;

[0056] The end of the screening component 2 is connected to a heating and mixing component 3, which is used to heat and evenly mix the cable skin. The screening component 2 transports the screened cable skin, and the cable skin enters the heating component and is stirred into a mass.

[0057] The discharge end of the heating and mixing component 3 is provided with a ring cutting component 4, and the agglomerated plastic is ring cut into plastic particles of uniform size after being extruded;

[0058] A cooling assembly 5 is provided below the ring cutting assembly 4 for cooling the plastic particles after ring cutting, and a collecting assembly 6 is provided below the cooling assembly 5 for collecting the cooled plastic particles;

[0059] The cooling component 5 is used to cool the plastic particles after the ring cutting. The cooled plastic particles gradually shrink and solidify. The collection component 6 is used to collect the cooled plastic particles, thus completing the production of plastic particles.

[0060] The above description is only a preferred embodiment of the utility model and does not limit the utility model in any form. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model.
