Description

TECHNICAL FIELD

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

[0002] The aluminum-plastic composite tape for cables is a composite material tape formed by compounding aluminum foil and plastic film (such as high-density polyethylene plastic), which combines the advantages of aluminum foil and plastic and has multiple properties such as light weight, corrosion resistance, heat resistance and insulation. When the aluminum-plastic composite tape is installed, the surface of the cable needs to be dry, clean and free of impurities such as oil stains, and the aluminum-plastic composite tape needs to be wrapped around the cable with the aluminum surface facing outward and the plastic film surface facing inward.

[0003] The existing production device for the aluminum-plastic composite tape mainly comprises a hot pressing assembly and a glue coating assembly. When the aluminum-plastic composite tape is produced, the glue coating assembly is used to coat glue on one side of the aluminum foil, and then the hot pressing assembly is used to press the plastic film on the end of the aluminum foil with the glue. The hot pressing assembly can heat to soften and melt the hot sealing glue. At the same time of heating, the material is pressed to ensure the close combination between the aluminum foil and the plastic film.

[0004] However, in the above technology, the glue on the aluminum foil needs to move a distance to reach the hot pressing assembly, so the glue may solidify during the movement. Since the aluminum foil is continuously moving during the whole process, the glue on the aluminum foil may pass through the hot pressing assembly before it is completely melted by the hot pressing assembly, thereby reducing the adhesion of the glue and the connection strength between the aluminum foil and the plastic film. SUMMARY

[0005] The application aims to provide a semiconductive aluminum-plastic composite tape for cables and a preparation device and method thereof, which can improve the adhesion 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.

[0027] In summary, the application has at least one of the following beneficial technical effects:

[0028] 1. The extrusion block in the present application is triangular in shape. When the aluminum foil passes through the extrusion block, the glue on the aluminum foil will be extruded by the extrusion block. When the glue is in a fluid state, it has good fluidity. Therefore, the two inclined sides of the triangular extrusion block 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 and falls off the aluminum foil. At this time, the falling glue will pass through the light emitted by the infrared emitter. Therefore, the light received by the infrared receiver will be reduced or not. The reduction or absence of the amount of light received by the infrared receiver indicates that the glue flows through the infrared emitted by the infrared emitter, and that the glue has good fluidity. If the infrared receiver continuously receives a certain amount of infrared, it indicates that no glue passes through the infrared, and that no glue flows down from the aluminum foil. This indicates that the fluidity of the glue on the aluminum foil is low, and the extrusion block cannot push the glue off the aluminum foil. Therefore, the infrared receiver will continuously receive a large amount of infrared for a period of time. The infrared receiver will then transmit a signal to the hot air assembly, which will increase the power and thus increase the temperature of the hot air, thereby increasing the temperature of the environment in which the glue is located. This helps to prevent the glue from solidifying due to a decrease in temperature, thereby increasing the adhesion of the glue and improving the connection strength between the aluminum foil and the plastic film, thereby improving the production quality of the aluminum-plastic composite tape;

[0029] 2. During the detection process of the detection assembly, the glue on the aluminum foil moves from the middle part of the aluminum foil to the edge parts of the aluminum foil, thereby moving the excess glue on the aluminum foil to the part of the aluminum foil where there is less glue or pushing it off the aluminum foil. This allows the glue to be evenly spread on the aluminum foil, which helps to ensure that each contact point between the aluminum foil and the plastic film is fully covered with glue, forming a stronger adhesive layer and improving the adhesion strength of the aluminum foil and the plastic film, thereby making the aluminum foil and the plastic film more firmly bonded together. At the same time, uniform application of glue can help to avoid the presence of air bubbles or gaps between the aluminum foil and the plastic film, thereby improving the overall production quality of the product;

[0030] 3. The setting of the discharge opening of the glue application assembly allows more glue to be applied to the middle part of the material in the lower feeding cylinder than to the two sides. Since the extrusion block can push the excess glue from the middle part of the aluminum foil to the two sides of the composite tape, the glue application assembly in the present application can apply relatively less glue than the glue application assembly in the prior art, which applies glue to the entire material. The extrusion block then extrudes the excess glue to every part of the composite tape, achieving the effect of saving resources as a whole;

[0031] 4. The hot air assembly is arranged to blow the glue on the lower feeding cylinder material from the middle to both sides, so that the glue can be relatively flat on the lower feeding cylinder material, which reduces the workload of the subsequent extrusion block, and further makes the glue on the aluminum foil more uniform, thereby further improving the production quality of the composite tape;

[0032] 5. The arrangement of the infrared emitter and the infrared receiver in the present application can not only detect whether the glue on the aluminum foil is in a solid state or a fluid state, but also detect whether the aluminum foil deviates during unwinding. When the aluminum foil deviates during unwinding, the infrared emitted by one of the infrared emitters will always irradiate on the aluminum foil, and the infrared emitted by the other infrared emitter will be able to continuously transmit to the corresponding infrared receiver. Therefore, when one of the infrared receivers can receive a certain amount of infrared for a long time, and the other infrared receiver does not receive any infrared, it indicates that the position of the aluminum foil deviates, thereby achieving the effect of detecting the position of the aluminum foil.

DETAILED DESCRIPTION

[0040] The following will be described in detail in combination with the accompanying Figures 1-6 The present application will be further described in detail. Embodiment 1

[0041] A semi-conductive aluminum plastic composite tape for cable comprises an aluminum foil layer, a glue layer and a plastic film layer, 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:

[0042] polybutadiene resin 30-50 parts, o-cresol formaldehyde epoxy resin 50-70 parts, tertiary amine 16-18 parts, methyl hexahydrophthalic anhydride 75-80 parts, and tertiary butyl catechol 5-8 parts.

[0043] The glue prepared according to the above ratio can quickly gel in a short time, has good bonding effect, so that the connection strength of the aluminum foil and the plastic film is higher, and the aluminum plastic composite tape prepared has relatively high quality. Embodiment 2

[0044] A preparation device of a semi-conductive aluminum plastic composite tape for cable, referring to Figures 1-6 , comprising: a machine body 1, a glue coating assembly 2, a hot pressing assembly 3, a detection assembly 4, and a hot air assembly 5.

[0045] The upper and lower feeding rollers are rotatably arranged on the machine body 1, the plastic film is wound on the upper feeding roller, and the aluminum foil is wound on the lower feeding roller.

[0046] The glue coating assembly 2 is installed on the machine body 1, and is used for smearing glue on the upper surface of the aluminum foil.

[0047] The hot pressing assembly 3 is installed on the machine body 1, and is used for pressing the plastic film on one end of the aluminum foil coated with glue.

[0048] The detection assembly 4 is installed on the machine body 1, and in the embodiment, the detection assembly 4 is located between the glue coating assembly 2 and the hot pressing assembly 3, and is used for detecting whether the glue on the aluminum foil is solidified.

[0049] The hot air assembly 5 is installed on the machine body 1, and in the embodiment, the hot air assembly 5 is located between the glue coating assembly 2 and the detection assembly 4, and can blow hot air on the side of the aluminum foil with glue, and when the detection assembly 4 detects that the glue on the aluminum foil is solidified, the output power of the hot air assembly 5 is increased.

[0050] The tail end of the machine body 1 is further provided with a winding assembly 7, and in the embodiment, the winding assembly 7 can pull the plastic film and the aluminum foil on the upper feeding cylinder 11 and the lower feeding cylinder 12, and at the same time, the winding assembly 7 can also wind the composite tape pressed by the hot pressing assembly 3.

[0051] When the device starts, the glue applying assembly 2 first applies glue to the upper surface of the aluminum foil, and then the hot air assembly 5 blows hot air on the aluminum foil coated with glue. After the glue is blown by the hot air, its temperature rises, and the relatively high temperature can avoid the glue from quickly solidifying, so as to keep it in a fluid state with good adhesion as much as possible. Then, when the detection assembly 4 detects that the glue is in a fluid state with good adhesion, the aluminum foil continues to move until it is pressed together with the plastic film by the hot pressing assembly 3. When the detection assembly 4 detects that the glue has solidified, the winding assembly 7, the upper supply cylinder 11, the lower supply cylinder 12 and the glue applying assembly 2 stop running. The detection assembly 4 sends a signal to the hot air assembly 5. After receiving the signal, the hot air assembly 5 increases its output power, so that the blown hot air has a higher temperature, so as to ensure that the glue is always in a fluid state with good adhesion, so that the connection strength between the plastic film and the aluminum foil is higher, and the production quality of the composite tape is improved.

[0052] With reference to Figure 3 and Figure 5 , the detection assembly 4 includes an extrusion block 41 and an infrared emitter 42.

[0053] The extrusion block 41 is provided with two extrusion blocks 41, which are arranged opposite to each other in the vertical direction. The aluminum foil passes between the two extrusion blocks 41. The two extrusion blocks 41 and the machine body 1 are provided with connecting rods 44. Each extrusion block 41 is connected to a connecting rod 44 on both sides. In the embodiment, four connecting rods 44 are provided. The extrusion block 41 in the embodiment is triangular. The top corner of the extrusion block 41 is located in the middle of the aluminum foil. The two bottom corners of the extrusion block 41 are located at the edges of the two sides of the aluminum foil. The top corner of the extrusion block 41 is relatively closer to the glue applying assembly 2.

[0054] The infrared emitter 42 is provided with two infrared emitters 42, which are arranged opposite to each other on both sides of the aluminum foil. The two infrared emitters 42 correspond to the two bottom corners of the extrusion block 41. The infrared emitter 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 below the aluminum foil. The two infrared receivers 43 correspond to the two infrared emitters 42 one by one. The shortest distance between the two infrared emitters 42 is the same as the width of the extrusion block 41 and the width of the aluminum foil.

[0055] When the aluminum foil with glue is passing through the extrusion block 41, the glue on the aluminum foil is extruded by the extrusion block 41. When the glue is in a fluid state with good viscosity, it has good fluidity, so the two oblique edges of the triangular extrusion block 41 can push the glue on the aluminum foil to move close to the edges 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 falling glue will pass through the light emitted by the infrared emitter 42, so the light reaching the infrared receiver 43 will be reduced or not. If the amount of light received by the infrared receiver 43 is reduced or not, it means that the glue flows through the infrared emitted by the infrared emitter 42, and that the glue has good fluidity. If the infrared receiver 43 continuously receives a certain amount of infrared, it means that no glue passes through the infrared, and that no glue flows down from the aluminum foil. This means that the fluidity of the glue on the aluminum foil is low, and the extrusion block 41 cannot push the solidified glue off the aluminum foil. Therefore, the infrared receiver 43 will continuously receive a large amount of infrared for a period of time, and the infrared receiver 43 will transmit a signal to the hot air assembly 5, which will increase the power, thereby increasing the temperature of the hot air and the temperature of the environment in which the glue is located, in order to avoid the phenomenon of solidification of the glue due to the decrease in temperature, thereby improving 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.

[0056] At the same time, since the extrusion block 41 is triangular, when the aluminum foil with glue passes through the triangular extrusion block 41, the glue on the aluminum foil moves from the middle part of the aluminum foil to the edge parts, so that the excess glue on the aluminum foil moves to the place where there is less glue on the aluminum foil, or falls off the aluminum foil, so that the glue can be evenly spread on the aluminum foil. It can ensure that every contact point between the aluminum foil and the plastic film is fully covered with glue to form a stronger adhesive layer, which helps to improve the adhesion strength of the aluminum foil and the plastic film, and makes the aluminum foil and the plastic film more firmly bonded together. At the same time, uniform glue application can avoid air bubbles or gaps between the aluminum foil and the plastic film, thereby further improving the production quality of the product as a whole.

[0057] In addition, the arrangement of the infrared emitter 42 and the infrared receiver 43 in the present application can not only detect whether the glue on the aluminum foil is in a solid state or a fluid state, but also detect whether the aluminum foil deviates during unwinding. When the aluminum foil deviates during unwinding, the infrared emitted by one of the infrared emitters 42 will always irradiate the aluminum foil, and the infrared emitted by the other infrared emitter 42 will be able to continuously transmit to the corresponding infrared receiver 43. Therefore, when one of the infrared receivers 43 can receive a certain amount of infrared for a long time, and the other infrared receiver 43 does not receive any infrared, it indicates that the position of the aluminum foil deviates, thereby achieving the effect of detecting the position of the aluminum foil.

[0058] With reference to Figure 1 and Figure 6 The glue applying assembly 2 in the embodiment includes a glue applying roller, which is hollow inside. The lower side of the glue applying roller is provided with a discharge port 21. One side of the glue applying roller is connected with an external glue supply device (not shown in the figure). The length of the discharge port 21 is less than the width of the material in the lower feeding cylinder 12, and the width of the middle part of the discharge port 21 is greater than the width of the two sides.

[0059] The discharge port 21 in the embodiment is arranged in a shape of wide in the middle and narrow on both sides. Therefore, when the glue applying roller applies glue to the aluminum foil, the glue on the middle part of the aluminum foil is relatively more than the glue on the two side parts. The extrusion block 41 in the embodiment is arranged in a triangular shape, which can push the excess glue on the middle part of the aluminum foil to the two sides of the composite tape. Therefore, compared with the glue applying assembly 2 in the prior art which applies glue to the entire material, the glue applying assembly 2 in the present application can apply relatively less glue, and then the extrusion block 41 extrudes the excess glue to each part of the composite tape, thereby achieving the effect of saving resources.

[0060] The hot air assembly 5 in the embodiment includes a blowing pipe, and the blowing pipe is provided with blowing ports 51 on the peripheral wall. The blowing ports 51 in the embodiment are also arranged from the middle to the two sides, so that the hot air blown out of the blowing ports 51 can blow the glue on the aluminum foil from the middle to the two sides, so that the glue can be relatively flat on the lower aluminum foil, which reduces the workload of the extrusion block 41, and further makes the glue applied on the aluminum foil more uniform, thereby further improving the production quality of the composite tape.

[0061] Wherein, the blowing pipe in the embodiment is provided with another air outlet 51 on the side close to the glue applying assembly 2, and the hot air blown from the air outlet 51 flows to the discharge port 21 of the glue applying roller, so as to avoid the glue adhering to the discharge port 21 of the glue applying assembly 2, and thus the glue applying assembly 2 is prevented from being blocked by the glue, and the stable operation of the equipment is ensured. Meanwhile, the hot air blown to the glue applying assembly 2 can melt the glue adhering to the discharge port 21 of the glue applying assembly 2, so that the glue can be fully utilized, and the waste of resources is reduced.

[0062] Secondly, referring to Figure 4 and Figure 6 , the machine body 1 is further provided with a collecting assembly 6 for collecting the glue falling from both sides of the aluminum foil. The collecting assembly 6 in the embodiment comprises a collecting box 61 installed on the machine body 1 and located directly below the extrusion block 41. One side of the collecting box 61 is provided with a conduit 62, and the conduit 62 is provided with a pump 63. The end of the conduit 62 away from the collecting box 61 is in communication with one side of the glue applying roller. The other side of the collecting box 61 is also provided with a conduit 62 and a pump 63, and the conduit 62 and the pump 63 on the other side of the collecting box 61 correspond to the other side of the glue applying roller.

[0063] When the excess glue is extruded from the surface of the aluminum foil by the extrusion block 41, the excess glue falls into the collecting box 61, and then the excess glue is transported into the glue applying roller through the pump 63 and the conduit 62, so that the excess glue can be recycled, and the waste of resources is further reduced.

[0064] It should be noted that the collecting box 61 and the conduit 62 are provided with heating assemblies (not shown in the figure), which can ensure that the glue is always in a flowing state, so that it can be stably transported into the glue applying roller. Embodiment 3

[0067] S2, tertiary amine is added to the preformed material, and after stirring, an intermediate material is obtained. Tert-butyl o-diphenol is added to the intermediate material, and is fully stirred and uniformly mixed to obtain the final glue;

[0068] S3, the aluminum foil is sleeved on the lower feeding cylinder 12, and the plastic film is sleeved on the upper feeding cylinder 11.

[0069] S4, the glue prepared in S2 is applied on the aluminum foil by the glue applying assembly 2, the glue on the aluminum foil is detected by the detecting assembly 4, when the detecting assembly 4 detects that the hardness of the aluminum foil is large, the power of the hot air assembly 5 is increased to ensure that the glue on the aluminum foil is in a flowing state;

[0070] S5, the plastic film and the aluminum foil coated with the glue are pressed by the hot pressing assembly 3 to obtain a composite tape.

[0071] The composite tape prepared by the above process has 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 the embodiment.

[0072] The embodiments of the specific embodiment are the preferred embodiments of the application, and are not intended to limit the protection scope of the application, wherein the same parts are denoted by the same reference numerals.
