Description

Technical Field

[0001] This utility model relates to the field of wire and cable processing, specifically to a device for melting raw materials used in wire and cable processing. Background Technology

[0002] Electric wires are conductors that transmit electrical energy. They are divided into bare wires, electromagnetic wires, and insulated wires. Bare wires have no insulation layer and include copper and aluminum flat wires, overhead stranded wires, and various profiles. They have a thin insulation layer and good electrical and mechanical properties, as well as properties such as heat resistance, moisture resistance, and solvent resistance. Different insulation materials can be selected to obtain different characteristics.

[0003] Chinese patent CN213353110U discloses a melting device for raw materials used in wire and cable processing. The device employs a multi-stage filtration technology to address the problem of harmful gases being generated during the melting process of wire and cable raw materials. The solution involves adding the raw materials into the interior of a heating frame and heating and melting them using an electric heating block.

[0004] Regarding the aforementioned technologies, in existing solutions, the electric heating block is located at the bottom of the heating frame. After the raw materials of the wires and cables are melted, they become liquid. The liquid raw materials are concentrated at the bottom of the heating frame by gravity and continue to contact the electric heating block. Meanwhile, the unmelted granular solid raw materials are located on top of the liquid raw materials. Due to the air between the solid particles, the heat from the electric heating block is difficult to conduct upwards efficiently to melt the granular raw materials above. In summary, existing raw material melting equipment for wire and cable processing is difficult to melt raw materials efficiently. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a melting device for raw materials used in wire and cable processing, so as to solve the technical problem that existing melting devices for raw materials used in wire and cable processing are unable to efficiently melt raw materials.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a raw material melting device for wire and cable processing, comprising a chassis, a rotating drum rotatably connected to the top of the chassis, a molten material tank for holding raw materials placed inside the rotating drum, and a mounting frame fixedly connected to the top of the chassis. The mounting frame is slidably connected to a telescopic shaft in the vertical direction, and a pressure plate fixedly connected to the bottom of the telescopic shaft to prevent the granular raw materials from sinking in. A first float box fixedly connected below the pressure plate to prevent the molten raw materials from sinking in, and a connecting frame fixedly connected to the bottom of the first float box. A heating rod for melting the raw materials is connected to the connecting frame.

[0007] By adopting the above technical solution, the rotary table drives the molten material tank to rotate, causing the molten material tank to rotate relative to the heating rod. At the same time, the heating rod is kept on the upper layer of the granular raw material in the molten material tank, allowing the molten raw material to penetrate downwards and fill the gaps. The unmelted raw material is kept at the height of the heating rod by its own buoyancy, so that the heating rod can continuously contact the unmelted granular raw material and accelerate the melting speed of the raw material.

[0008] The present invention is further configured such that a protective box is fixedly connected to the top of the chassis, the mounting bracket and the rotating drum are both located inside the protective box, and the top and bottom of the protective box are respectively provided with an exhaust port and an air inlet for displacing the gas inside the protective box.

[0009] Preferably, the protective box can effectively prevent the leakage of waste gas generated during the melting of raw materials.

[0010] The present invention is further configured such that a rotating platform is provided at the top of the chassis, and a rotating drum is rotatably connected to the rotating platform. A waist-shaped receiving groove is provided inside the rotating drum. When the molten material barrel is located at one end of the receiving groove, the molten material barrel and the rotating drum are coaxial; otherwise, when it is located at the other end, they are not coaxial.

[0011] Preferably, the rotating drum's receiving trough allows the molten material drum to move inside.

[0012] The present invention is further configured such that the top end of the rotating platform and the bottom end of the rotating drum are provided with mutually compatible inclined surfaces, and rollers are provided in the inclined surfaces.

[0013] Preferably, the rotation of the drum is achieved stably.

[0014] The present invention is further configured such that a counterweight is fixedly connected to one side of the top of the molten material barrel, and when the molten material barrel is placed in one end of the receiving groove and is coaxial with the rotating barrel, the counterweight is located on the molten material barrel near the other end of the receiving groove.

[0015] Preferably, increasing the rotation speed of the drum allows the molten material drum to move more easily to the eccentric position.

[0016] The present invention is further configured such that the outer wall of the telescopic shaft is provided with a guide groove along the axial direction, and a protrusion that slides in the guide groove is fixedly connected inside the mounting bracket.

[0017] Preferably, the telescopic shaft is prevented from rotating along its own axis.

[0018] The present invention is further configured such that heating rods are rotatably connected to both sides of the connecting frame, and the heating rods are restricted by the upper limit structure of the connecting frame so that they cannot continue to rotate downward after being kept horizontal, and a second float box is fixedly connected to the end of the heating rod away from the connecting frame.

[0019] Preferably, when the raw materials are swirling in the molten tub after melting, the heating rod can be rotated and lifted to more fully heat the raw materials in the molten tub.

[0020] The present invention is further configured such that the telescopic axis extends upward through the protective box, and a control box is fixedly connected to the top end.

[0021] Preferably, a control box is used to control the heating rod to generate heat.

[0022] The present invention is further configured such that the height of the molten material barrel is higher than that of the rotating barrel, and a handle is fixedly connected at a position above the top of the rotating barrel.

[0023] Preferably, the molten material bucket can be easily lifted out of the rotating drum using a handle.

[0024] The present invention is further configured such that the distance between the position of the mounting bracket connecting the telescopic shaft and the top of the rotating drum is greater than the height of the molten material drum.

[0025] Preferably, this avoids situations where the molten material bucket cannot be placed into the receiving tank.

[0026] In summary, the present invention has the following main advantages:

[0027] 1. This utility model uses a rotating table to drive the molten material tank to rotate, causing the molten material tank to rotate relative to the heating rod. At the same time, the heating rod is kept on the upper layer of the granular raw material in the molten material tank, allowing the molten raw material to penetrate downwards and fill the gaps. The unmelted raw material is kept at the height of the heating rod by its own buoyancy, so that the heating rod can continuously contact the unmelted granular raw material and accelerate the melting speed of the raw material.

[0028] 2. This utility model provides a waist-shaped receiving groove inside the rotating drum, so that after the granular raw materials inside the molten drum have melted, they can move to a position eccentric to the rotating table due to their own centrifugal force. By controlling the rotation of the rotating table in both directions, the raw materials inside the molten drum can be further shaken evenly, allowing the heating rod to better heat the remaining unmelted raw materials.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0039] The embodiments of this utility model will be described below based on its overall structure.

[0040] First embodiment:

[0041] Please refer to the following: A raw material melting device for wire and cable processing. Figure 1-7 It includes a chassis 1, with a rotating drum 4 rotatably connected to the top of the chassis 1. A molten material tank 8 for holding raw materials is placed inside the rotating drum 4. Specifically, in order to save energy and maintain the temperature of the molten raw materials, the rotating drum 4 has a heat preservation function.

[0042] It also includes a mounting bracket 5, which is fixedly connected to the top of the chassis 1. The mounting bracket 5 is slidably connected to a telescopic shaft 6 in the vertical direction. The bottom end of the telescopic shaft 6 is fixedly connected to a pressure plate 10 to prevent the granular raw materials from sinking. The bottom of the pressure plate 10 is fixedly connected to a first float box 11 to prevent the molten raw materials from sinking. The bottom end of the first float box 11 is fixedly connected to a connecting frame 12. The connecting frame 12 is connected to a heating rod 13 for melting the raw materials. Since the granular raw materials used for wire and cable processing inevitably contain some air during production, the density of the granular raw materials will be less than the density of the molten raw materials. During the melting process of the raw materials in the melting tank 8, the unmelted granular raw materials will slowly float to the height of the heating rod 13. The heating rod 13 can conduct heat more quickly, causing this part of the raw materials to melt quickly.

[0043] For details regarding the above embodiments, please refer to [link / reference]. Figure 1-2 The top of the chassis 1 is fixedly connected to a protective box 2. The mounting bracket 5 and the rotating drum 4 are both located inside the protective box 2. The top and bottom of the protective box 2 are respectively provided with an exhaust port 202 and an air inlet 201 for replacing the gas inside the protective box 2. The protective box 2 can effectively prevent the leakage of waste gas generated during the melting of raw materials. After the air inlet 201 and the exhaust port 202 are connected to an air filter, they can effectively filter the waste gas generated during the melting of raw materials for wire and cable processing.

[0044] For details regarding the above embodiments, please refer to [link / reference]. Figure 5-7 The outer wall of the telescopic shaft 6 is provided with a guide groove 601 along the axial direction. A protrusion that slides in the guide groove 601 is fixedly connected inside the mounting bracket 5, so that the telescopic shaft 6 cannot rotate along its own axis, thus preventing the heating rod 13 from rotating along with the melting tank 8 during rotation. Furthermore, the telescopic shaft 6 extends upward through the protective box 2, and a control box 7 is fixedly connected to the top. The control box 7 is used to control the heating of the heating rod 13. Specifically, the control box 7 is equipped with a controller for controlling the heating of the heating rod 13. The heating principle of the heating rod 13 is resistance wire heating.

[0045] Second embodiment:

[0046] Please refer to the following: A raw material melting device for wire and cable processing. Figure 1-7 A rotating platform 3 is provided at the top of the casing 1. A rotating drum 4 is rotatably connected to the rotating platform 3. A waist-shaped receiving groove 401 is provided inside the rotating drum 4. When the molten material barrel 8 is located at one end of the receiving groove 401, the molten material barrel 8 and the rotating drum 4 are coaxial. Conversely, when it is located at the other end, they are not coaxial. The receiving groove 401 of the rotating drum 4 allows the molten material barrel 8 to move inside.

[0047] Specifically, a counterweight 9 is fixedly connected to one side of the top of the molten material barrel 8. When the molten material barrel 8 is placed in one end of the receiving groove 401 and is coaxial with the rotating barrel 4, the counterweight 9 is located on the molten material barrel 8 near the other end of the receiving groove 401. This allows the molten material barrel 8 to move to the eccentric position more effectively after the rotation speed of the rotating barrel 4 is increased.

[0048] Furthermore, the top of the rotating platform 3 and the bottom of the rotating drum 4 are provided with mutually compatible inclined surfaces, and rollers are provided in the inclined surfaces to stably realize the rotation of the rotating drum 4 and prevent the rotating drum 4 from shaking during the rotation process.

[0049] For details regarding the above embodiments, please refer to [link / reference]. Figure 2-3 The height of the molten material barrel 8 is higher than that of the rotating barrel 4, and a handle is fixedly connected at a position above the top of the rotating barrel 4. During the process of putting in or taking out the molten material barrel 8, the staff can conveniently lift the molten material barrel 8 out of the rotating barrel 4 using the handle.

[0050] Furthermore, the distance between the position of the mounting bracket 5 and the telescopic shaft 6 and the top of the rotating drum 4 is greater than the height of the molten material drum 8, so as to prevent the molten material drum 8 from being unable to be placed into the receiving slot 401.

[0051] Third embodiment:

[0052] Please refer to the following: A raw material melting device for wire and cable processing. Figure 1-7 Heating rods 13 are rotatably connected to both sides of the connecting frame 12. The heating rods 13 are restricted by the upper limit structure of the connecting frame 12 and cannot continue to rotate downward after being kept horizontal. A second float box 14 is fixedly connected to the end of the heating rod 13 away from the connecting frame 12. When the raw material is melted and shakes in the melting tank 8 to generate a vortex, the heating rod 13 can be adaptively rotated and lifted to heat the raw material in the melting tank 8 more fully.

[0053] Specifically, after the raw material melts in the melting tank 8, the rotating tank 4 rotates, causing the melted raw material in the melting tank 8 to be subjected to its own centrifugal force. The liquid level near the center is lower than the liquid level near the inner wall. At this time, under the buoyancy of the second float box 14, the heating rod 13 will tilt upward slightly. The specific tilting height is adapted to the liquid level difference between the center liquid level and the edge liquid level in the melting tank 8, so as to ensure that the heating rod 13 can better heat the raw material on the surface of the melting tank 8.

[0054] In the specific process of melting raw materials for wire and cable processing, the present invention first pours the granular raw materials into the melting tank 8. Then, the melting tank 8 is placed in the receiving tank 401, coaxial with the rotating tank 4. The counterweight 9 of the melting tank 8 is aligned with the other end of the receiving tank 401. When the granular raw materials on the inner surface of the melting tank 8 have not melted, the pressure plate 10 contacts the granular raw materials in the melting tank 8 to prevent the heating rod 13 from sinking. During the rotation of the rotating tank 4, the heating rod 13 fully contacts the granular raw materials, allowing them to melt and seep downwards. The unmelted granular material floats up and continues to contact and melt with the heating rod 13. After most of the raw material in the melting tank 8 has melted, the heating rod 13 will not sink due to the buoyancy of the first float box 11. It will remain on the surface of the raw material to heat the last few granular materials. Then the rotation speed of the rotating tank 4 gradually increases, and the melting tank 8 slides to the other end of the receiving tank 401 under its own centrifugal force. The melted raw material in the melting tank 8 is shaken evenly during the reciprocating forward and reverse rotation of the rotating tank 4, thereby completing the efficient melting of the raw materials for wires and cables.

[0055] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
