Description

Technical Field

[0001] The present application relates to the technical field of cable manufacturing, and in particular to a semi-conductive aluminum-plastic composite tape for cables and a preparation device and method thereof. Background Art

[0002] Cable aluminum-plastic composite tape is a composite tape made of aluminum foil and plastic film (such as high-density polyethylene plastic) through composite processing. This material combines the advantages of aluminum foil and plastic, and has multiple properties such as light weight, corrosion resistance, heat resistance, and insulation. When installing the aluminum-plastic composite tape, you need to pay attention to: Make sure that the cable surface is dry, clean, and free of impurities such as oil, and wrap the entire cable with the aluminum side of the aluminum-plastic composite tape facing outward and the plastic film side facing inward.

[0003] The equipment for producing aluminum-plastic composite tape in the prior art mainly includes a hot pressing component and a glue coating component. When producing the aluminum-plastic composite tape, glue is first applied to one side of the aluminum foil by the glue coating component, and then the plastic film is pressed onto the end of the aluminum foil with glue by the hot pressing component. The hot pressing component can generate heat to soften and melt the heat-sealing glue. While heating, the materials are pressed to ensure a tight bond between the aluminum foil and the plastic film.

[0004] However, in the above technology, since the glue on the aluminum foil needs to move a certain distance to reach the hot pressing assembly, the glue may solidify during this movement. In addition, since the aluminum foil is continuously moving during the whole process, the glue on the aluminum foil may not be completely melted before passing through the hot pressing assembly, resulting in a decrease in the viscosity of the glue, thereby reducing the connection strength between the aluminum foil and the plastic film. Summary of the invention

[0005] The purpose of the present application is to provide a semi-conductive aluminum-plastic composite tape for cables and a preparation device and method thereof, which can improve the viscosity of the glue, thereby improving the connection strength between the aluminum foil and the plastic film, and further improving the production quality of the aluminum-plastic composite tape.

The hot air component can blow hot air to the glue on the surface of the material on the lower feeding barrel, and when the detection component detects that the glue on the surface of the material on the lower feeding barrel is solidified, the output power of the hot air component increases.

The two infrared transmitters correspond to the two bottom corners of the extrusion block. The infrared transmitter is located at the upper end of the material on the lower feeding barrel, and the output end is perpendicular to the plane of the material on the lower feeding barrel. Two infrared receivers are arranged below the material on the lower feeding barrel. The two infrared receivers correspond one-to-one to the two infrared transmitters. The shortest distance between the infrared rays emitted by the two infrared transmitters is the same as the width of the extrusion block and the width of the material on the lower feeding barrel.

[0008] Optionally, a discharge port is provided on the glue coating component, the length of the discharge port is smaller than the width of the material in the lower feed barrel, and the width of the middle part of the discharge port is greater than the width on both sides.

[0009] Optionally, a hot air component is provided on the machine body, and the hot air component is located between the glue coating component and the hot pressing component. The hot air component can blow the glue on the material of the lower feed barrel from the middle to both sides, and the hot air blown by the hot air component can ensure that the glue is in a fluid state.

[0010] Optionally, the hot air component can also blow air to the abutment area between the glue coating component and the material on the lower feeding barrel to prevent the cooled glue from adhering to the discharge port of the glue coating component.

[0011] Optionally, a collecting component is provided on the machine body, and the collecting component is used to collect excess glue on both sides of the material in the lower feeding barrel.

[0012] Optionally, the collecting assembly includes a collecting box, a conduit is provided on one side of the collecting box, a pump is provided on the conduit, and one end of the conduit away from the collecting box is connected to the glue coating assembly.

[0013] In a second aspect, the present application provides a method for preparing a semi-conductive aluminum-plastic composite tape for a cable, comprising the following steps: S1, adding polybutadiene resin and o-cresol epoxy resin into a reaction kettle, stirring and heating, and adding methyl hexahydrophthalic anhydride into the reaction kettle to obtain a prefabricated material; S2, adding tertiary amine into the prefabricated material, stirring to obtain an intermediate material, adding tert-butyl catechol into the intermediate material, stirring well to obtain the final glue; S3, sleeve the aluminum foil onto the lower feeding cylinder and sleeve the plastic film onto the upper feeding cylinder; S4, applying the glue prepared in S2 on the aluminum foil through the glue coating component, and the detection component detects the glue on the aluminum foil. When the detection component detects that the hardness of the aluminum foil is relatively large, the power of the hot air component is increased to ensure that the glue on the aluminum foil is in a fluid state; S5. The hot pressing assembly presses the plastic film and the aluminum foil coated with glue to obtain a composite tape.

[0014] In a third aspect, the present application provides a semi-conductive aluminum-plastic composite tape for a cable, comprising an aluminum foil layer, a glue layer, and a plastic film layer, wherein the glue layer is located between the aluminum foil layer and the plastic film layer, and the glue layer comprises the following components by weight: 30-50 parts of polybutadiene resin, 50-70 parts of o-cresol epoxy resin, 16-18 parts of tertiary amine, 75-80 parts of methyl hexahydrophthalic anhydride, and 5-8 parts of tert-butyl catechol.

[0015] In summary, the present application includes at least one of the following beneficial technical effects: 1. The extrusion block in the present application is set to be triangular in shape. When the aluminum foil passes through the extrusion block, the glue on the aluminum foil will be squeezed by the extrusion block. When the glue is in a fluid state, it has good fluidity. Therefore, the two oblique sides of the triangular extrusion block can push the glue on the aluminum foil along the edges of both sides of the aluminum foil until the glue moves to the bottom corner of the extrusion block and falls off the aluminum foil. At this time, the fallen glue will pass through the light emitted by the infrared transmitter, so the light reaching the infrared receiver will be reduced or absent. The reduction or absence of the amount of light received by the infrared receiver indicates that the glue has flowed through the infrared light emitted by the infrared transmitter, and that the glue has good fluidity. ; If the infrared receiver continuously receives a certain amount of infrared rays, it means that no glue passes through the infrared rays, and no glue flows down from the aluminum foil, which means that the fluidity of the glue on the aluminum foil is low, and it is difficult for the extrusion block to push the glue off the aluminum foil. Therefore, the infrared receiver continuously receives a large amount of infrared rays for a period of time, and the infrared receiver will transmit the signal to the hot air component, and the hot air component will increase the power, thereby increasing the temperature of the hot air, thereby increasing the temperature of the environment where the glue is located, so as to avoid the phenomenon of glue solidification due to the decrease in temperature, thereby increasing the viscosity of the glue and the connection strength between the aluminum foil and the plastic film, thereby improving the production quality of the aluminum-plastic composite tape; 2. During the inspection of the inspection component, since the extrusion block is set in a triangular shape, the glue on the aluminum foil moves from the middle part of the aluminum foil along the edge parts on both sides, so that the excess glue on the aluminum foil moves to the place where there is less glue on the aluminum foil, or is pushed to the outside of the aluminum foil, so that the glue can be relatively evenly spread on the aluminum foil, which can ensure that every contact point between the aluminum foil and the plastic film can be fully covered by the glue to form a stronger bonding layer, which helps to improve the bonding strength of the aluminum foil and the plastic film as a whole, so that the aluminum foil and the plastic film are more firmly combined together; at the same time, the uniform application of glue can avoid the appearance of bubbles or gaps between the aluminum foil and the plastic film as much as possible, thereby improving the production quality of the product as a whole; 3. The setting of the discharging port of the glue coating component can make the glue applied to the middle part of the material of the lower feeding barrel be more than that on the two sides, and because the extrusion block can push the excess glue in the middle part of the aluminum foil to the two sides of the composite belt, therefore, compared with the glue coating component in the prior art that coats the entire material with glue, the glue coating component in the present application can apply relatively less glue, and then the extrusion block squeezes the excess glue to every part of the composite belt, which achieves the effect of saving resources as a whole; 4. The setting of the hot air component, on the one hand, the hot air component can blow the glue on the material of the lower feeding barrel from the middle to both sides, so that the glue can be relatively flat on the material of the lower feeding barrel, which reduces the workload of the subsequent extrusion block and further makes the glue applied on the aluminum foil more uniform as a whole, thereby further improving the production quality of the composite tape; 5. The setting of the infrared transmitter and the infrared receiver in the present application can not only detect whether the glue on the aluminum foil is in a solidified state or a fluid state, but also detect whether the aluminum foil is offset during the unwinding process. When the aluminum foil is offset during the unwinding process, the infrared rays emitted by one of the infrared transmitters will continue to irradiate the aluminum foil, and the infrared rays emitted by the other infrared transmitter will be able to continuously transmit to the corresponding infrared receiver. Therefore, when one infrared receiver can receive a certain amount of infrared rays for a long time, while the other infrared receiver does not receive any infrared rays, it means that the position of the aluminum foil has shifted, thereby achieving the effect of detecting the position of the aluminum foil.

DETAILED DESCRIPTION

[0017] The following is combined with Figure 1-6 , further details of this application are given. Example 1

[0018] A semi-conductive aluminum-plastic composite tape for a cable, comprising an aluminum foil layer, a glue layer, and a plastic film layer, wherein the glue layer is located between the aluminum foil layer and the plastic film layer, and the glue layer comprises the following components by weight: 30-50 parts of polybutadiene resin, 50-70 parts of o-cresol epoxy resin, 16-18 parts of tertiary amine, 75-80 parts of methyl hexahydrophthalic anhydride, and 5-8 parts of tert-butyl catechol.

[0019] The glue prepared according to the above ratio can gel quickly in a short time and has a good bonding effect, thereby making the connection strength between the aluminum foil and the plastic film higher, and thus making the prepared aluminum-plastic composite tape have a relatively high quality. Example 2

[0020] A preparation device for semi-conductive aluminum-plastic composite tape for cables, referring to Figure 1-Figure 6 , including: a body 1, a gluing component 2, a hot pressing component 3, a detection component 4, and a hot air component 5.

[0021] An upper feeding roller and a lower feeding roller are rotatably arranged on the machine body 1. The upper feeding roller is wound with a plastic film, and the lower feeding roller is wound with an aluminum foil.

[0022] The glue coating component 2 is installed on the body 1, and the glue coating component 2 is used to apply glue to the upper surface of the aluminum foil.

[0023] The hot pressing assembly 3 is installed on the machine body 1, and the hot pressing assembly 3 is used to press the plastic film onto the end of the aluminum foil coated with glue.

[0024] The detection component 4 is installed on the machine body 1. The detection component 4 in this embodiment is located between the glue coating component 2 and the hot pressing component 3. The detection component 4 is used to detect whether the glue on the aluminum foil is solidified.

[0025] The hot air component 5 is installed on the body 1. In this embodiment, the hot air component 5 is located between the glue coating component 2 and the detection component 4. The hot air component 5 can blow hot air to the side of the aluminum foil with glue, and when the detection component 4 detects that the glue on the aluminum foil is solidified, the output power of the hot air component 5 increases.

[0026] A winding assembly 7 is also provided at the rear end of the machine body 1. The winding assembly 7 in this embodiment can pull the plastic film and aluminum foil on the upper feeding drum 11 and the lower feeding drum 12. At the same time, the winding assembly 7 can also wind up the composite tape pressed by the hot pressing assembly 3.

[0027] When the equipment is started, the glue coating component 2 will first apply glue to the upper surface of the aluminum foil, and then the hot air component 5 will blow hot air to the aluminum foil coated with glue. After the glue is blown by the hot air, its temperature will rise, and the relatively high temperature can avoid the glue from solidifying quickly as much as possible, thereby trying to keep it in a fluid state with good viscosity. Then, after the subsequent detection component 4, when the detection component 4 detects that the glue is in a fluid state with good viscosity, the aluminum foil will continue to move until it is pressed together with the plastic film by the hot pressing component 3. When the detection component 4 detects that the glue has solidified, the winding component 7, the upper feed drum 11, the lower feed drum 12 and the glue coating component 2 will stop running, and the detection component 4 will send the detection signal to the hot air component 5. After receiving the signal, the hot air component 5 will increase its own output power, so that the blown hot air has a higher temperature to ensure that the glue is always in a fluid state with good viscosity, thereby making the connection strength between the plastic film and the aluminum foil higher, thereby improving the production quality of the composite tape.

[0028] Reference Figure 3 and Figure 5 The detection component 4 includes an extrusion block 41 and an infrared emitter 42.

[0029] There are two extrusion blocks 41, which are arranged opposite to each other in the vertical direction, and the aluminum foil passes through the two extrusion blocks 41. A connecting rod 44 is provided between the two extrusion blocks 41 and the body 1, and each extrusion block 41 is connected to a connecting rod 44 on both sides. In this embodiment, a total of four connecting rods 44 are provided. The extrusion block 41 in this embodiment is arranged in a triangular shape, and the top corner of the extrusion block 41 is located in the middle of the aluminum foil, and the two bottom corners of the extrusion block 41 are located at the edges of both sides of the aluminum foil. The top corner of the extrusion block 41 is relatively closer to the glue coating component 2.

[0030] There are two infrared transmitters 42, which are arranged on both sides of the aluminum foil. The two infrared transmitters 42 correspond to the two bottom corners of the extrusion block 41. The infrared transmitter 42 is located at the upper end of the aluminum foil, and the output end is perpendicular to the plane where the aluminum foil is located. Two infrared receivers 43 are arranged under the aluminum foil. The two infrared receivers 43 correspond to the two infrared transmitters 42 one by one. The shortest distance between the infrared rays emitted by the two infrared transmitters 42 is the same as the width of the extrusion block 41 and the width of the aluminum foil.

[0031] When the aluminum foil coated with glue passes through the extrusion block 41, the glue on the aluminum foil will be squeezed by the extrusion block 41. When the glue is in a fluid state with good viscosity, it has good fluidity. Therefore, the two oblique sides of the triangular extrusion block 41 can push the glue on the aluminum foil along the edges of the two sides of the aluminum foil until the glue moves to the bottom corner of the extrusion block 41 and falls off the aluminum foil. At this time, the fallen glue will pass through the light emitted by the infrared transmitter 42, so the light reaching the infrared receiver 43 will be reduced or absent. The reduction or absence of the amount of light received by the infrared receiver 43 indicates that the glue flows through the infrared light emitted by the infrared transmitter 42, and the glue has good fluidity. ; If the infrared receiver 43 continuously receives a certain amount of infrared rays, it means that no glue passes through the infrared rays, and no glue flows down from the aluminum foil, which means that the fluidity of the glue on the aluminum foil is low, and it is difficult for the extrusion block 41 to push the solidified glue off the aluminum foil. Therefore, the infrared receiver 43 continuously receives a large amount of infrared rays for a period of time, and the infrared receiver 43 will transmit the signal to the hot air component 5, and the hot air component 5 will increase the power, thereby increasing the temperature of the hot air, thereby increasing the temperature of the environment in which the glue is located, so as to avoid the phenomenon of glue solidification due to the decrease in temperature as much as possible, thereby increasing the viscosity of the glue and the connection strength between the aluminum foil and the plastic film, thereby improving the production quality of the aluminum-plastic composite tape.

[0032] At the same time, since the extrusion block 41 is set in a triangular shape, when the aluminum foil coated with glue passes through the triangular extrusion block 41, the glue on the aluminum foil moves from the middle part of the aluminum foil along the edge parts on both sides, so that the excess glue on the aluminum foil moves to the place where there is less glue on the aluminum foil, or is pushed off the aluminum foil, so that the glue can be relatively evenly spread on the aluminum foil, which can ensure that every contact point between the aluminum foil and the plastic film can be fully covered by the glue to form a stronger bonding layer, which helps to improve the bonding strength between the aluminum foil and the plastic film as a whole, so that the aluminum foil and the plastic film are more firmly combined together; at the same time, the uniform application of glue can avoid the appearance of bubbles or gaps between the aluminum foil and the plastic film as much as possible, thereby further improving the production quality of the product as a whole.

[0033] In addition, the setting of the infrared transmitter 42 and the infrared receiver 43 in the present application can not only detect whether the glue on the aluminum foil is in a solidified state or a fluid state, but also detect whether the aluminum foil is offset during the unwinding process. When the aluminum foil is offset during the unwinding process, the infrared rays emitted by one of the infrared transmitters 42 will continue to irradiate the aluminum foil, and the infrared rays emitted by the other infrared transmitter 42 will be able to continuously transmit to the corresponding infrared receiver 43. Therefore, when one infrared receiver 43 can receive a certain amount of infrared rays for a long time, while the other infrared receiver 43 does not receive any infrared rays, it means that the position of the aluminum foil has shifted, thereby achieving the effect of detecting the position of the aluminum foil.

[0034] Reference Figure 1 and Figure 6 The glue coating component 2 in this embodiment includes a glue coating roller, which is hollow inside. A discharge port 21 is provided on the lower peripheral wall of the glue coating roller. One side of the glue coating roller is connected to an external glue supply device (shown in the figure). The length of the discharge port 21 is smaller than the width of the material in the lower supply barrel 12, and the width of the middle part of the discharge port 21 is greater than the width on both sides.

[0035] The discharge port 21 in the present embodiment is configured to be wide in the middle and narrow on both sides. Therefore, when the glue roller is applying glue to the aluminum foil, the glue in the middle part of the aluminum foil is relatively more than the glue on the two side parts. Since the extrusion block 41 in the present embodiment is configured to be triangular in shape, it can push the excess glue in the middle part of the aluminum foil to both sides of the composite strip. Therefore, compared with the gluing component 2 in the prior art that coats the entire material with glue, the gluing component 2 in the present application can apply relatively less glue, and then the extrusion block 41 squeezes the excess glue to every part of the composite strip, thereby achieving the effect of saving resources as a whole.

[0036] The hot air assembly 5 in this embodiment includes a blowing pipe, and a blowing port 51 is opened on the peripheral wall of the blowing pipe. The blowing port 51 in this embodiment is also arranged to be inclined from the middle to both sides, so that the hot air blown out from the blowing port 51 can blow the glue on the aluminum foil from the middle to both sides, so that the glue can be relatively flat on the lower aluminum foil, which reduces the workload of the subsequent extrusion block 41, and further makes the glue applied on the aluminum foil more uniform as a whole, thereby further improving the production quality of the composite tape.

[0037] Among them, another blowing port 51 is provided on the side of the blowing pipe close to the glue coating component 2 in this embodiment, and the hot air blown out from the blowing port 51 flows to the discharge port 21 of the glue coating roller to avoid the cooled glue adhering to the discharge port 21 of the glue coating component 2, thereby avoiding the glue blocking the discharge port 21 of the glue coating component 2 as much as possible, and thus ensuring the stable operation of each component of the equipment as much as possible; at the same time, the hot air blown to the glue coating component 2 can melt the glue adhering to the discharge port 21 of the glue coating component 2 and make it drip on the aluminum foil, so that the glue can be fully utilized and the waste of resources is reduced.

[0038] Secondly, refer to Figure 4 and Figure 6 The machine body 1 is also provided with a collecting assembly 6 for collecting the glue dropped from both sides of the aluminum foil. The collecting assembly 6 in this embodiment includes a collecting box 61, which is installed on the machine body 1 and is located directly below the extrusion block 41. A conduit 62 is provided on one side of the collecting box 61, and a pump 63 is provided on the conduit 62. One end of the conduit 62 away from the collecting box 61 is connected to one side of the glue coating roller, and the other side of the collecting box 61 is also provided with a conduit 62 and a pump 63. The conduit 62 and the pump 63 on the other side of the collecting box 61 correspond to the other side of the glue coating roller.

[0039] When the excess glue is squeezed out of the surface of the aluminum foil by the extrusion block 41, the excess glue falls into the collection box 61, and then is transported to the glue coating roller through the pump 63 and the conduit 62, so that the excess glue can be recycled, thereby further reducing the waste of resources.

[0040] It should be noted that heating components (not shown in the figure) are provided on the collection box 61 and the conduit 62 to ensure that the glue is always in a flowing state so that it can be stably transported to the glue coating roller. Example 3

[0041] A method for preparing a semi-conductive aluminum-plastic composite tape for a cable comprises the following steps: S1, adding polybutadiene resin and o-cresol epoxy resin into a reaction kettle, stirring and heating, and adding methyl hexahydrophthalic anhydride into the reaction kettle to obtain a prefabricated material; S2, adding tertiary amine into the prefabricated material, stirring to obtain an intermediate material, adding tert-butyl catechol into the intermediate material, stirring well to obtain the final glue; S3, sleeve the aluminum foil onto the lower feeding cylinder 12, and sleeve the plastic film onto the upper feeding cylinder 11; S4, applying the glue prepared in S2 on the aluminum foil through the glue coating component 2, and the detection component 4 detects the glue on the aluminum foil. When the detection component 4 detects that the hardness of the aluminum foil is relatively large, the power of the hot air component 5 is increased to ensure that the glue on the aluminum foil is in a fluid state; S5, the hot pressing component 3 presses the plastic film and the aluminum foil coated with glue to obtain a composite tape.

[0042] The composite tape produced by the above process has a higher connection strength between the plastic layer and the aluminum foil layer, thereby greatly improving the production quality of the aluminum-plastic composite tape in this embodiment.

[0043] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
