Description

Technical Field

[0001] The invention relates to cable copper wire processing equipment, in particular to cable copper wire preheating equipment. Background Art

[0002] The main component of wires and cables is copper wire, which needs to be covered with an insulating layer. The processing process is to transfer the copper wire to the insulating coating position, and then wrap the insulating layer around the outside of the copper wire after melting, thereby improving the stability of the copper wire. Before the copper wire is coated, in order to improve the coordination effect between the copper wire and the insulating layer, the copper wire is usually preheated.

[0003] Existing copper wire preheating equipment mostly uses electromagnetic heating during the preheating process. The copper wire is heated by setting an electromagnetic heating structure on the wheel body. Although it can dry and clean the copper wire, it will leave dirt on the copper wire. Therefore, some solutions will extract the air in the electromagnetic heating cavity to take out the dirt. However, this way of taking out dirt will not only cause a large loss of heat, but also easily cause the copper wire with a small aperture to break, thereby interrupting the entire preheating process.

[0004] Therefore, this case aims to provide a copper wire preheating device for cables, which not only preheats the copper wire before it is formally coated with rubber, but also allows the liquid or dirt that may exist on the copper wire to be contained in the heating structure and passed to the outside during the preheating stage, keeping the surface of the copper wire smooth, thereby improving the coordination effect between the copper wire and the insulation layer, and allowing the copper wire to transmit signals more smoothly. Summary of the invention

[0008] Several groups of guided heat exchange structures, several groups of heating terminals are arranged in the machine, the guided heat exchange structures include heat-conducting rods connected to the heating terminals, the ends of the heat-conducting rods are sleeved with a contact cylinder, the contact cylinder is rotatably mounted on a mounting frame, the heating terminals heat the heat-conducting rods and conduct heat to the contact cylinders, the copper wires enter through the wire inlet, are guided and heated by several contact cylinders, and are output from the wire outlets;

[0010] As a further improvement, a plurality of guide grooves are provided on the contact cylinder, and the copper wire passes around one of the guide grooves.

[0011] As a further improvement, the mounting frame includes a first mounting seat fixed to the inner wall of the preheating box, the contact cylinder is circumferentially mounted in the first mounting seat, and a second mounting seat is installed at the other end of the contact cylinder. Bearings are provided in the first mounting seat and the second mounting seat, and the contact cylinder is connected to two bearings.

[0012] As a further improvement, the distance between the two mounting frames is defined as L, and the length of the heating tube is defined as 1 / 2L.

[0013] As a further improvement, the first extrusion component and the second extrusion component are of similar size and structure. The first extrusion component includes a rubber cylinder partially embedded in the outside of the heating tube and movably cooperates with the heating tube. A driving structure is provided on the outside of the rubber cylinder. When the driving structure is actuated, it drives the rubber cylinder to move toward the inside of the heating tube.

[0014] As a further improvement, the driving structure includes a connecting arm for connecting the heating tube and the mounting frame, and a push-pull power member is provided on the outer side of the connecting arm. The push-pull power member is connected to the rubber cylinder through a steering arm, and when the push-pull power member is pulled back, it drives the steering arm and the rubber cylinder to move toward the inner side of the heating tube.

[0016] As a further improvement, the docking assembly includes a plurality of spaced-apart snap-fit ​​blocks arranged axially on the inner side of the rubber cylinder, and a plurality of suction holes are provided on the snap-fit ​​blocks. When the opposing rubber cylinders abut against each other, the snap-fit ​​blocks are inserted into the gaps between the opposing snap-fit ​​blocks, and the dirt or liquid droplets in the gaps are drawn away through the suction holes by the external separation tube.

[0017] As a further improvement, the wire inlet and the wire outlet are both provided with sealing rings, and the sealing rings include an outer fixing ring arranged in the hole, and an inner elastic ring is fixedly connected to the outer side of the outer fixing ring.

[0018] As a further improvement, an adjustment structure is provided at the lower end of the mounting plate, and the adjustment structure includes an elastic plate connected to the lower end of the mounting plate, and the lower end of the elastic plate is connected to an adjustment member.

[0019] The beneficial effects of the present invention are:

[0020] In traditional copper wire preheating equipment, most of them adopt the method of directly supplying heat in the entire preheating structure, so that the copper wire is directly preheated in the preheating structure to remove the water vapor and impurities that may be attached to it. However, a large amount of heat will be taken away while the impurities and water vapor are removed. Therefore, in this case, through the setting of the guided heat exchange structure, first of all, the basic heat source is concentrated only on the contact cylinder, and the copper wire will be heated only when it passes through the position of the contact cylinder. The contact cylinder can not only guide the copper wire, but also heat it. Moreover, since the heat conducting rod as the heat source is not in direct contact with the copper wire, there is no phenomenon of heating and deforming the copper wire, which is safer during the preheating process.

[0021] Since the copper wire may have different entry angles, if the copper wire is tilted too much, it may be stretched too tight and break. Therefore, the present invention provides a plurality of guide grooves in the contact cylinder to guide the contact cylinder, thereby allowing the entire copper wire to be transmitted with optimal tension.

[0022] The copper wire is in a state of continuous movement during the transmission process. If the contact cylinder does not move, the contact between the copper wire and the contact cylinder is relatively awkward. Although the purpose of preheating can still be achieved, the copper wire is easily worn and loss is easily caused. Therefore, the present invention arranges the contact cylinder in a mounting frame, and the contact cylinder can rotate in the first mounting seat and the second mounting seat, so that it rotates along with the transmission of the copper wire, thereby improving the transmission efficiency of the copper wire.

[0023] In fact, there is a certain gap between each contact tube. However, if a contact tube is directly added, the copper wire will be subjected to too much force, which will hinder its normal transmission. However, if the heating structure is not set, the heat gap between the contact tubes will be difficult to fill. Therefore, the present invention provides a temperature-raising cleaning structure on the basis of the guided heat exchange structure. By setting a heating tube in the gap between the contact tubes, the copper wire can be heated by the heating tube after being heated by the contact tube. Although the caliber of the heating tube is larger than the diameter of the copper wire, the copper wire can still be heated in a wrapped manner. However, water vapor and dirt are easily retained in the tubular structure. Therefore, the present invention provides a first extrusion component and a second extrusion component on both sides of the heating tube. The first extrusion component and the second extrusion component can be intermittently extended into the heating tube to hang the droplets and dirt in the heating tube to the middle area, and then the droplets and dirt are extracted through the external separation tube, thereby achieving a local and continuous heating effect, while ensuring the cleanliness of the tube and avoiding secondary contamination of the copper wire.

[0024] Since the copper wire is continuously input, water vapor and dirt are actually generated intermittently. If the first extrusion component and the second extrusion component are set to a fixed state, the droplets and impurities precipitated by heating will fall on the inner side of the first extrusion component and the second extrusion component, and cannot be extracted by the external separation tube. Therefore, the present invention sets the first extrusion component to a movable state, and the rubber cylinder in the first extrusion component is driven by a driving structure, so that the rubber cylinder can clean the droplets and dirt in the heating tube after a certain period, thereby ensuring the cleanliness of the heating tube, thereby improving the preheating quality of the copper wire and the subsequent rubber coating quality.

[0025] During the use of the driving structure, it is necessary to make room for the copper wire, so it cannot be directly set on the axial position of the rubber cylinder. Therefore, the present invention first fixes the heating tube through the driving structure to prevent it from being suspended in the air, and then installs the push-pull power part in the gap between the connecting arms to provide space for the displacement of the steering arm, thereby better driving the rubber cylinder to reciprocate back and forth.

[0026] After the two push-pull power parts are actuated, the rubber cylinders will be close to each other. In order to prevent the rubber cylinders from being tightly attached to each other and leaving no suction space, a docking assembly is provided on the rubber cylinder in the present invention. The docking assembly enables the two rubber cylinders to fit closely to each other while having a certain gap. Even if the push-pull power parts retract excessively, there is still a certain gap between the two, thereby ensuring the extraction effect of droplets and dirt.

[0027] In order to improve the limiting effect on the copper wire and also to prevent the wire inlet and wire outlet holes of the entire box from damaging the copper wire, the present invention arranges sealing rings at the wire inlet and wire outlet holes. Through the arrangement of the outer fixing ring and the inner elastic ring in the sealing ring, the copper wire is not easily damaged by friction even if there is passive fluctuation.

[0028] Since different cables use copper wires with different specifications, the tensions of different copper wires are different, and the preheating time and travel of the copper wires are also different during preheating. Therefore, the present invention provides an adjustment structure on the mounting plate, so that the height of the preheating box can be adjusted, thereby making the preheating time of the copper wire controllable and adjustable according to the needs of the copper wire.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0041] Reference Figure 1 to Figure 7As shown, a copper wire preheating device for cables comprises a machine 10, on which a mounting plate 20 is arranged, on which a preheating box 30 is arranged, on which a preheating box 30 is arranged, and on which a wire inlet hole and a wire outlet hole for copper wire to enter and exit are opened, on which two sides of the front of the machine 10 are respectively provided with a first lead frame 11 and a second lead frame 12, and in the middle of the machine 10 is provided a guide frame 13, and the copper wire preheating device for cables also comprises: a plurality of guide heat exchange structures 40, in which a plurality of heating terminals are arranged, and the guide heat exchange structures 40 comprise a heat conducting rod 41 connected to the heating terminal, and a contact cylinder 42 is sleeved at the end of the heat conducting rod 41, and the contact cylinder 42 is rotatably mounted on a mounting frame 43, and the heating terminal heats the heat conducting rod 41 and conducts heat to the contact cylinder 42, and the copper wire enters through the wire inlet and is heated in the guide heating of the plurality of contact cylinders 42 Then it is output from the outlet; several groups of temperature-raising cleaning structures 50, including a heating tube 51 arranged between two mounting frames 43, the inner diameter of the heating tube 51 is larger than the copper wire, and the first extrusion component 52 and the second extrusion component 53 are respectively arranged at both ends of the heating tube 51, and a docking component is arranged at the position opposite to the first extrusion component 52 and the second extrusion component 53, and the first extrusion component 52 and the second extrusion component 53 are arranged on the side away from each other. An external separation tube 55 is provided, and when the heating tube 51 heats the copper wire, the first extrusion component 52 and the second extrusion component 53 intermittently squeeze into the heating tube 51 and squeeze the water vapor and dirt in the heating tube 51 to the middle position of the heating tube 51, and then the water vapor and dirt are extracted through the external separation tube 55, and the first extrusion component 52 and the second extrusion component 53 in different groups of the temperature-raising cleaning structures 50 are squeezed in at different times.

[0042] During the copper wire preheating stage, after the copper wire is released in the previous step, it will be input through the first lead frame 11, and enter the wire inlet hole of the preheating box 30 under the guidance of the guide frame 13. The copper wire entering the preheating box 30 is heated to a certain temperature under the action of the guide heat exchange structure 40 and the temperature-raising cleaning structure 50, and then output through the wire outlet hole, and then out again from the second lead frame 12 under the guidance of the guide frame 13, thereby achieving the cleaning and heating of the copper wire, and better cooperation with the insulation layer during rubber encapsulation.

[0043] In traditional copper wire preheating equipment, most of them adopt a method of directly supplying heat to the entire preheating structure, so that the copper wire is directly preheated in the preheating structure to remove the water vapor and impurities that may be attached to it. However, a large amount of heat will be taken away while removing the impurities and water vapor. Therefore, in this case, through the setting of the guide heat exchange structure 40, first, the basic heat source is concentrated only on the contact cylinder 42, and the copper wire will be heated only when it passes through the position of the contact cylinder 42. The contact cylinder 42 can not only guide the copper wire, but also heat it. Moreover, since the heat conducting rod 41 as the heat source is not in direct contact with the copper wire, there is no phenomenon of heating and deforming the copper wire, which is safer during the preheating process.

[0044] Since the copper wire may have different entry angles, if the copper wire is tilted too much, it may be stretched too tight and break. Therefore, a plurality of guide grooves are provided on the contact cylinder 42 of this embodiment, and the copper wire passes around one of the guide grooves. By providing a plurality of guide grooves in the contact cylinder 42, the contact cylinder 42 can be guided, so that the entire copper wire can be transmitted with an optimal tension, and can adapt to copper wires with different entry angles and different thicknesses.

[0045] The copper wire is in a state of continuous movement during the transmission process. If the contact cylinder 42 does not move, the contact between the copper wire and the contact cylinder 42 is relatively rough. Although the preheating purpose can still be achieved, the copper wire is easily worn and loss is easily caused. Therefore, the mounting frame 43 of this embodiment includes a first mounting seat 431 fixed to the inner wall of the preheating box 30, and the contact cylinder 42 is circumferentially mounted in the first mounting seat 431. The other end of the contact cylinder 42 is mounted with a second mounting seat 432. The first mounting seat 431 and the second mounting seat 432 are both provided with bearings. The contact cylinder 42 is connected to the two bearings, and the contact cylinder 42 is set in a mounting frame 43. The contact cylinder 42 can rotate in the first mounting seat 431 and the second mounting seat 432, so that it rotates along with the transmission of the copper wire, thereby improving the transmission efficiency of the copper wire. The first mounting seat 431 and the second mounting seat 432 are always fixed, and only the internal bearings and the contact cylinder 42 move.

[0046] There is actually a certain gap between each contact cylinder 42 and each contact cylinder 42. However, if the contact cylinder 42 is directly added, the copper wire will be subjected to too much force, which will hinder its normal transmission. However, if the heating structure is not provided, the heat gap between the contact cylinders 42 and the contact cylinders 42 is difficult to fill. Therefore, the present invention provides a temperature-raising cleaning structure 50 on the basis of the guided heat exchange structure 40. By providing a heating tube 51 in the gap between the contact cylinders 42, the copper wire can be heated by the heating tube 51 after being heated by the contact cylinder 42, and the heating tube 51 is Although the caliber is larger than the diameter of the copper wire, the copper wire can still be wrapped and heated. However, water vapor and dirt are easily retained in the tubular structure. Therefore, the present invention provides a first squeezing component 52 and a second squeezing component 53 on both sides of the heating tube 51. The first squeezing component 52 and the second squeezing component 53 can be intermittently inserted into the heating tube 51 to hang the droplets and dirt in the heating tube 51 to the middle area, and then the droplets and dirt are extracted through the external separation tube 55, thereby achieving a local and continuous heating effect, while ensuring the cleanliness of the tube and avoiding secondary contamination of the copper wire.

[0047] In order to set up a heating structure between the two contact cylinders 42 without affecting the setting of the entire cleaning structure, the spacing between the two mounting frames 43 in this embodiment is defined as L, and the length of the heating tube 51 is 1 / 2L, providing sufficient space for the movement of the heating cleaning structure 50.

[0048] Since the copper wire is continuously input, water vapor and dirt are actually generated intermittently. If the first extrusion component 52 and the second extrusion component 53 are set to a fixed state, the droplets and impurities precipitated by heating will fall on the inner side of the first extrusion component 52 and the second extrusion component 53, and cannot be extracted by the external separation tube 55. Therefore, the first extrusion component 52 and the second extrusion component 53 of this embodiment have the same structure and size. The first extrusion component 52 includes a rubber cylinder 521 that is partially embedded in the outer side of the heating tube 51 and movably cooperates with the heating tube 51. A driving structure is provided on the outer side of the rubber cylinder 521. When the driving structure is actuated, the rubber cylinder 521 is driven to move toward the inner side of the heating tube 51. The first extrusion component 52 is set to a movable state. The rubber cylinder 521 in the first extrusion component 52 is driven by the driving structure. After a certain period of time, the rubber cylinder 521 can clean the droplets and dirt in the heating tube 51, thereby ensuring the cleanliness of the heating tube 51, thereby improving the preheating quality of the copper wire and the subsequent rubber coating quality.

[0049] During the use of the driving structure, it is necessary to make room for the copper wire, so it cannot be directly set on the axial position of the rubber cylinder 521. Therefore, the present invention sets up a driving structure, which includes a connecting arm 5221 for connecting the heating tube 51 and the mounting frame 43. A push-pull power member 5222 is set on the outer side of the connecting arm 5221. The push-pull power member 5222 is connected to the rubber cylinder 521 through a steering arm 5223. When the push-pull power member 5222 is pulled back, it drives the steering arm 5223 and the rubber cylinder 521 to move toward the inner side of the heating tube 51. First, the heating tube 51 is fixed to prevent it from being suspended in the air. Secondly, the push-pull power member 5222 is installed in the gap between the connecting arms 5221 to provide a space for the displacement of the steering arm 5223, thereby better driving the rubber cylinder 521 to make back and forth reciprocating motion.

[0050] The entire steering arm 5223 is divided into three parts. The steering arm 5223 includes a power part 231 connected to the power end of the push-pull power member 5222. The power part 231 is laterally connected to a bending part 232. The bending part 232 is connected to a boosting part 233. The boosting part 233 is connected to the axial edge of the heating tube 51. The steering arm 5223 has a U-shaped structure, so that it can pass through the gap between the two connecting arms 5221 while achieving the effect of reversing linkage.

[0051] After the two push-pull power members 5222 are actuated, the rubber cylinders 521 will be close to each other. In order to prevent the rubber cylinders 521 from being tightly attached to each other and having no suction space, the docking assembly of this embodiment includes a plurality of spaced-apart snap-fit ​​blocks 541 arranged on the inner axial direction of the rubber cylinder 521. The snap-fit ​​blocks 541 are provided with a plurality of suction holes. When the opposing rubber cylinders 521 abut against each other, the snap-fit ​​blocks 541 are inserted into the gap between the opposing snap-fit ​​blocks 541, and the dirt or liquid droplets in the gap are sucked away through the suction holes via the external separation member tube 55. By arranging a docking assembly on the rubber cylinder 521, the two rubber cylinders can cooperate with each other and be close to each other while having a certain gap. Even if the push-pull power member 5222 retracts excessively, there is still a certain gap between the two, thereby ensuring the effect of removing liquid droplets and dirt.

[0052] In order to improve the limiting effect on the copper wire and also to prevent the inlet and outlet holes of the entire box from damaging the copper wire, the present invention provides a sealing ring 60 at the inlet and outlet holes. The inlet and outlet holes are both provided with sealing rings 60, and the sealing ring 60 includes an outer fixing ring 61 set in the hole position, and the outer side of the outer fixing ring 61 is fixedly connected with an inner elastic ring 62. Through the arrangement of the outer fixing ring 61 and the inner elastic ring 62 in the sealing ring 60, the copper wire is not easily damaged by friction even if there is passive fluctuation.

[0053] Since different cables use copper wires of different specifications, different copper wires have different tensions, and the preheating time and travel of the copper wires are also different during preheating. Therefore, the present invention provides an adjustment structure 70 on the mounting plate 20, and an adjustment structure 70 is provided at the lower end of the mounting plate 20. The adjustment structure 70 includes an elastic plate 71 connected to the lower end of the mounting plate 20, and an adjustment member 72 is connected to the lower end of the elastic plate 71, so that the height of the preheating box 30 can be adjusted, thereby making the preheating time of the copper wire controllable and adjustable according to the needs of the copper wire.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
