Description

Technical Field

[0001] The invention relates to a vertical processing device for cables, belonging to the technical field of cable processing. Background Art

[0002] Wires and cables are wire products used to transmit electrical (magnetic) energy, information, and achieve electromagnetic energy conversion. In a broad sense, wires and cables are also referred to as cables. In a narrower sense, cables refer to insulated cables, which can be defined as a collection of the following components: one or more insulated wire cores, and their respective coatings, protective layers, and outer sheaths.

[0003] The outer protective layer of wires and cables is also called the outer protective sheath. The existing silicone rubber extrusion production line mainly includes equipment such as pay-off, front traction, extruder, vulcanization pipe, rear traction, and take-up. It usually adopts a catenary vulcanization tube vulcanization process and a horizontal hot drying tunnel vulcanization process. However, since the silicone rubber vulcanization shaping time is less than 2 minutes, and during this period, the cable cannot be supported by the wire guide wheel, and the length from the head to the shaping end is less than 10 meters, without the support of the wire guide wheel, the excessively long cable will not only sag under its own weight, but also cause the cable to shake due to the instability of traction, resulting in poor cable molding quality. Summary of the Invention

[0004] The purpose of the present invention is to provide a vertical processing device for cables. The vertical production line can control the heating temperature of different vulcanization tubes and adjust them according to the different vulcanization states at different parts to improve the overall vulcanization quality and vulcanization efficiency of the cable.

[0005] To achieve the above-mentioned object, the technical solution adopted by the present invention is: a vertical processing device for cables, comprising a pay-off drum, a first traction machine, an oven, an extruder, a vulcanizing device, a second traction machine and a take-up drum installed in sequence, the vulcanizing device comprising an upward vulcanizing section, a downward vulcanizing section and a reversing wheel, the upward vulcanizing section and the downward vulcanizing section are arranged side by side and vertically, the reversing wheel is located above the upward vulcanizing section and the downward vulcanizing section, the shortest distance between the parallel line segments of the cable passing through the upward vulcanizing section and the downward vulcanizing section is a first length, the diameter of the reversing wheel is the same as the first length, the pay-off drum and the take-up drum are installed side by side on the ground and correspond to the upward vulcanizing section and the downward vulcanizing section respectively, and a guide wheel is installed directly below each of the upward vulcanizing section and the downward vulcanizing section;

[0006] Each of the upward vulcanization section and the downward vulcanization section includes at least two vulcanization tubes, and a gap is defined between two adjacent vulcanization tubes in the downward vulcanization section. Two driven wheels are installed in the gap, and the two driven wheels clamp the two sides of the cable and are in pressure-free contact with the cable. The vulcanization tube further includes two vulcanization tube units, which are butt-jointed and have vulcanization cavities on the butt-jointed sides. The two vulcanization cavities form a vulcanization through-hole for the cable to pass through. At least one vulcanization tube unit of a vulcanization tube is mounted on a frame or wall via a cylinder, and the cylinder is mounted on the side of the vulcanization tube unit facing away from the vulcanization cavity.

[0007] A preheater is installed between the upward vulcanization section and the extruder, and the preheater includes an insulating tube, a spiral copper tube coil, and a cooling tube. The inner diameter of the insulating tube is larger than the outer diameter of the cable. The spiral copper tube coil is wound around the outer circumference of the insulating tube and is electrically connected to a high-frequency power supply. The high-frequency power supply is used to pass a high-frequency current converted from direct current into the spiral copper tube coil, thereby generating an alternating electromagnetic field. The cooling tube is wound around the outer circumference of the insulating tube and is connected to a water cooling box.

[0008] A vertical wire storage rack is installed between the second traction machine and the wire take-up drum. The vertical wire storage rack includes a vertical pole, a first wire storage wheel and a second wire storage wheel. The first wire storage wheel is installed on the vertical pole through a bracket, and the second wire storage wheel is installed on the vertical pole through a sliding rack. A spark tester, a printing press and an electrostatic powder coater are installed in sequence between the vertical wire storage rack and the wire take-up drum.

[0009] The further improved scheme in the above technical scheme is as follows:

[0010] 1. In the above solution, the vertical pole is configured as an H-shaped steel, which includes a base plate and wing plates installed on both sides of the base plate.

[0011] 2. In the above solution, the sliding frame is mounted on a wing plate, the inner side of the sliding frame has a first limiting wheel located on both sides of the wing plate, and the outer side of the sliding frame has a second limiting wheel.

[0012] 3. In the above solution, the peripheral wall of the second limiting wheel contacts the outer wall of the wing plate, the wing plate is embedded between the first limiting wheel and the second limiting wheel, and the sliding frame is further provided with a positioning bolt that is in compression contact with the vertical rod.

[0013] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0014] 1. The present invention is a vertical processing device for cables, wherein the vulcanizing device includes an ascending vulcanizing section, a descending vulcanizing section, and a reversing wheel. By separating the vulcanizing device into the vertically arranged ascending and descending vulcanizing sections, the rubber, which is in a thermoplastic state and has a low hardness after extrusion, does not experience eccentricity on the conductor due to gravity, as is the case with conventional horizontal production lines, where the conductor of the cable is in a horizontal state. This affects the production quality of the cable and reduces the defective rate of the finished product. This also solves the problem of jitter caused by the lack of support guide wheels in the first two vulcanizing pipe sections of horizontal production lines. By setting up the upward vulcanization section and the downward vulcanization section in sections and coordinating the pay-off drum and the take-up drum arranged side by side on the ground, the space occupied by the vulcanization device in the vertical direction can be reduced, thereby reducing the difficulty of installation and operation, and the layout of the remaining equipment can be regularized, making it convenient for the staff to perform pay-off and take-up operations at the same position, reducing labor input and improving processing efficiency. At the same time, by setting the diameter of the reversing wheel to be the same as the shortest distance between the two parallel parts of the cable, the reversal of the cable at the top of the upward vulcanization section and the downward vulcanization section can be achieved, and by increasing the diameter of the reversing wheel, the stress on the cable during reversal is reduced, thereby reducing its impact on the size and shape of the cable after initial vulcanization, thereby improving the quality of the cable.

[0015] 2. The vertical processing device for cables of the present invention comprises an upward vulcanization section and a downward vulcanization section, each of which comprises at least two vulcanization tubes, and a gap is provided between two adjacent vulcanization tubes of the upward vulcanization section or the downward vulcanization section. The vulcanization tube further comprises two vulcanization tube units, the two vulcanization tube units being butt-jointed and having a vulcanization cavity formed on the butt-jointed side. The two vulcanization cavities form a vulcanization through-hole for the passage of the cable. At least one vulcanization tube unit of a vulcanization tube is mounted on a frame or a wall by a cylinder. On the one hand, the vertically running cable does not overhang horizontally. Since no space is required for the overhang, the diameter of the vulcanization through-hole can be greatly reduced, thereby reducing the space required for heating the vulcanization tube and significantly improving the heating efficiency. This effectively improves the processing efficiency while reducing the production energy consumption. On the other hand, by splitting the upward vulcanization section or the downward vulcanization section into Multiple vulcanization tubes arranged at intervals can not only improve the overall vulcanization quality and vulcanization efficiency of the cable by controlling the heating temperature of different vulcanization tubes and adjusting them according to the different vulcanization states at different parts, but also observe the vulcanization state of the rubber through the gaps, which is convenient for staff to debug and operate. The heat in the vulcanization tube at the bottom can enter the vulcanization tube above with the rising hot air, further reducing energy consumption and improving energy utilization. In addition, the vulcanization tube unit is driven by a cylinder to make the vulcanization tube open. It can not only be fully opened to facilitate threading, but also leave only the lowest section of the upward vulcanization section open after threading is completed, which is convenient for startup debugging, appearance and structure inspection, and when the machine is stopped to change the reel for wiring, the fully opened vulcanization tubes can quickly dissipate the heat at the vulcanization device, avoiding excessive cross-linking of the rubber and oxidation of the conductor in the vulcanization tube, thereby improving the quality of the cable.

[0016] 3. A vertical processing device for a cable according to the present invention includes a preheater installed between the upstream vulcanization section and the extruder. The preheater includes a water cooling system, an insulating tube, a spiral copper tube coil, and a cooling tube. The inner diameter of the insulating tube is larger than the outer diameter of the cable. The spiral copper tube coil is wound around the outer circumference of the insulating tube and electrically connected to a high-frequency power supply. High-frequency current converted from direct current is passed through the copper tube coil, generating an alternating electromagnetic field. The magnetic lines of force of the electromagnetic field generate strong eddy currents when passing through the metal conductor, causing the metal conductor to rapidly heat itself, thereby achieving independent heating of the conductor. After the heated conductor and rubber enter the upstream vulcanization section, the vulcanization tube heats the rubber from the outside inward, while the high-temperature conductor heats the rubber from the inside out. This synchronizes the vulcanization speed and crosslinking degree of the inner and outer rubber layers, thereby reducing the stress difference between the inner and outer layers after vulcanization and crosslinking. This prevents the insulation layer from cracking due to the large amount of internal stress that would affect its service life when the cable is formed and used, thereby improving the cable quality.

[0017] 4. The present invention is a vertical processing device for cables, wherein a vertical wire storage rack is installed between the second traction machine and the take-up reel. The vertical wire storage rack includes a vertical pole, a first wire storage wheel, and a second wire storage wheel. Through the cooperation of the first wire storage wheel and the second wire storage wheel in the vertical wire storage rack, the vertical wire storage rack can continue to store the wire pulled out by the second traction machine after the wire on the vertical wire storage rack is disconnected from the take-up reel, thereby avoiding the need to stop the machine when the take-up reel is changed or when there is a problem with the equipment behind the vertical wire storage rack, which affects the processing efficiency of the cable; the extruder is installed on the upward vulcanizing section and the corresponding guide wheel By installing the extruder between the upward vulcanizing section and the corresponding guide wheel, the stress caused by the guide wheel reversing the cable can be avoided from affecting the size and shape of the rubber extruded on the conductor, thereby destroying the molding of the cable; the oven is installed between the first traction machine and the corresponding guide wheel. Before extruding the rubber, the conductor is preheated by the oven installed in front of the guide wheel. This can not only eliminate impurities such as moisture and oil on the surface of the conductor and reduce the bulging problem of the cable in the vulcanizing device, but also avoid excessive temperature difference between the conductor and the rubber when extruding the rubber, which can affect the molding quality of the rubber on the conductor surface.

[0018] 5. The vertical processing device for cables of the present invention has a transparent tube installed at its gap, which is connected to two vulcanization through-holes on both sides of the gap. The addition of the transparent tube will not hinder the staff from observing the vulcanization of the cable through the gap, and can also guide the heat generated in the lower vulcanization tube to rise, thereby improving its utilization rate; two driven wheels are installed at the gap of its descending vulcanization section, and these two driven wheels are clamped on both sides of the cable and in pressure-free contact with the cable. The driven wheels arranged at the descending vulcanization section stabilize the routing of the cable, thereby improving the overall processing quality of the cable, and at this time, the rubber on the cable has almost completed vulcanization and cross-linking, and the pressure-free contact of the driven wheels will not affect its size and shape; a material retaining plate is installed at the bottom end of its ascending vulcanization section, and the material retaining plate installed below the vulcanization through-hole can collect impurities precipitated on the inner wall of the vulcanization tube during vulcanization of the cable in the ascending vulcanization section, thereby preventing impurities from falling on the equipment below the ascending vulcanization section and affecting the normal use of these equipment.

[0041] A vertical wire storage rack 7 is installed between the second traction machine 41 and the wire take-up drum 4. The vertical wire storage rack 7 includes a vertical pole 71, a first wire storage wheel 72 and a second wire storage wheel 73.

[0043] When the vertical processing device for cables is used, the vulcanizing device is divided into a vertically arranged upward vulcanizing section and a downward vulcanizing section. As a result, the rubber in a thermoplastic state and with a lower hardness after extrusion will not be eccentrically applied to the conductor under the action of gravity, unlike in a traditional horizontal production line where the conductor of the cable is in a horizontal state, thereby affecting the preparation quality of the cable and reducing the defective rate of the finished product. At the same time, the shaking problem caused by the lack of support guide wheels in the first two sections of the vulcanizing pipeline of the horizontal production line is solved.

[0044] The segmented arrangement of the upward vulcanizing section and the downward vulcanizing section, in conjunction with the pay-off and take-up reels arranged side by side on the ground, can not only reduce the space occupied by the vulcanizing device in the vertical direction, thereby reducing the difficulty of installation and operation, but also standardize the layout of other equipment, making it convenient for workers to perform pay-off and take-up operations at the same location, reducing labor input and improving processing efficiency. At the same time, by setting the diameter of the reversing wheel to be the same as the shortest distance between the two parallel parts of the cable, the cable at the top of the upward vulcanizing section and the downward vulcanizing section can be reversed. By increasing the diameter of the reversing wheel, the stress on the cable during reversal is reduced, thereby reducing its impact on the size and shape of the cable after preliminary vulcanization, thereby improving the quality of the cable.

[0045] In addition, on the one hand, the vertically oriented cable will not produce horizontal overhang. Since there is no need to provide space for overhang, the aperture of the vulcanization through-hole can be greatly reduced, so that the space required for heating the vulcanization tube is reduced, and its heating efficiency is greatly improved. While reducing production energy consumption, it effectively improves processing efficiency. On the other hand, by splitting the upward vulcanization section or the downward vulcanization section into multiple vulcanization tubes with intervals, it is possible to control the heating temperature of different vulcanization tubes and adjust them according to the different vulcanization states at different parts to improve the overall vulcanization quality and vulcanization efficiency of the cable, and it is also possible to observe the vulcanization state of the rubber through the gap. , which is convenient for staff to debug and operate, and the heat in the vulcanization tube at the bottom can enter the vulcanization tube above with the rising hot air, further reducing energy consumption and improving energy utilization rate; in addition, the vulcanization tube unit is driven by the cylinder to make the vulcanization tube open. It can not only be fully opened to facilitate threading, but also leave only the lowest section of the upward vulcanization section open after the threading is completed, which is convenient for startup debugging, appearance and structure inspection, and when the machine is stopped to change the reel for wiring, the fully opened vulcanization tube can quickly dissipate the heat at the vulcanization device, avoiding excessive cross-linking of the rubber and oxidation of the conductor in the vulcanization tube, so as to improve the quality of the cable;

[0046] In addition, by passing high-frequency current converted from direct current into the spiral copper tube coil, an alternating electromagnetic field is generated when passing through the spiral copper tube coil. When the magnetic lines of force of the electromagnetic field pass through the conductor of the metal material, strong eddy currents are generated, causing the conductor of the metal material to heat up quickly by itself, thereby achieving separate heating of the conductor. After the heated conductor and rubber enter the upward vulcanization section, the vulcanization tube heats the rubber from the outside to the inside, and the high-temperature conductor heats the rubber from the inside to the outside, thereby synchronizing the vulcanization speed and cross-linking degree of the inner and outer layers of the rubber, thereby reducing the stress difference between the inner and outer layers of the rubber after vulcanization and cross-linking. When the cable is formed and used, the insulation layer will not crack due to the large amount of internal stress in itself, affecting its service life, thereby improving the quality of the cable.

[0047] In addition, by cooperating with the first storage wheel and the second storage wheel in the vertical storage rack, the cable on the vertical storage rack can continue to store the cable pulled out by the second traction machine after the cable on the vertical storage rack is disconnected from the take-up reel, avoiding the need to stop the machine when the take-up reel is changed or when there is a problem with the equipment behind the vertical storage rack, which affects the cable processing efficiency; by installing the extruder between the upward vulcanization section and the corresponding guide wheel, the stress of the guide wheel when reversing the cable is avoided from affecting the size and shape of the rubber extruded on the conductor, thereby damaging the molding of the cable; before extruding the rubber, the conductor is preheated in an oven installed in front of the guide wheel, which not only eliminates impurities such as moisture and oil on the surface of the conductor and reduces the bulging problem of the cable in the vulcanization device, but also avoids excessive temperature difference between the conductor and the rubber when extruding the rubber, which affects the molding quality of the rubber on the conductor surface;

[0048] In addition, the addition of a transparent tube will not hinder the staff from observing the cable vulcanization situation through the gap, and can also guide the heat generated in the downward vulcanization tube to rise, thereby improving its utilization rate; the driven wheel set at the downward vulcanization section stabilizes the cable routing, thereby improving the overall processing quality of the cable, and at this time the rubber on the cable has almost completed vulcanization and cross-linking, and the pressure-free contact of the driven wheel will not affect its size and shape; the material retaining plate installed below the vulcanization through-hole is used to collect impurities precipitated onto the inner wall of the vulcanization tube during the vulcanization of the cable in the upward vulcanization section, thereby preventing impurities from falling on the equipment below the upward vulcanization section and affecting the normal use of these equipment.
