Description

Technical Field

[0001] The present invention relates to the technical field of cable materials, and more particularly to a semi-conductive nylon tape for cables and a preparation device thereof. Background Art

[0002] Semi-conductive nylon tape for cables is a special material used in cables. It has a certain conductivity, but it is not a complete conductor. In high-voltage cables, the use of semi-conductive nylon tape can form a shielding layer, which helps to evenly distribute the electric field and reduce the risk of insulation breakdown caused by excessive local electric field strength. Semi-conductive nylon tape can also prevent static electricity accumulation, improve interface properties and provide mechanical protection, thereby improving the overall performance and safety of the cable.

[0003] The semi-conductive nylon tape for traditional cables includes a base layer and a coating layer. During the processing of the semi-conductive nylon tape, the key to determining its production quality is the coating process of setting the coating layer on the base layer. In the prior art, the adhesive used for the coating layer is applied to the base layer. As the base layer is continuously conveyed, a leveling plate is used to scrape the adhesive on the base layer. The excess adhesive will accumulate on the front side of the leveling plate. Since the flow direction of the adhesive accumulated on the front side of the leveling plate cannot be controlled, in order to prevent the adhesive from flowing out along the length direction of the leveling plate, partitions are set on both sides of the leveling plate. The partitions can prevent the adhesive accumulated on the front side of the leveling plate from flowing out from both sides of the leveling plate. In order to prevent the adhesive from flowing and sticking to the guide roller, the length of the leveling plate and the spacing between the two partitions are both smaller than the width of the base layer. When the processing is completed, the parts on both sides of the base layer that are not coated with adhesive are cut.

[0004] However, cutting and discarding the portion of the base layer that does not contain the coating layer will directly lead to a waste of materials, which will not only increase production costs, but also increase process complexity, extend production cycles, reduce production efficiency, and limit the size specifications of the final product. Summary of the invention

[0046] Embodiment 2

[0047] Based on the semi-conductive nylon tape for cables provided in Example 1, the present invention also provides a preparation process for the semi-conductive nylon tape for cables, referring to the attached specification. Figure 2 , including the following steps:

[0048] Step 1: Make a base layer 1. According to the product specifications, select nylon fabric to make a base layer 1 that meets the requirements;

[0049] Step 2: Clean the surface of the base layer 1 to remove debris, for example, by using an air blowing device to blow air, with the air blowing direction away from the output direction of the fabric base material to reduce the possibility of impurities being blown to the gluing position;

[0050] Step 3: Apply the coating layer 11, apply the coating layer 11 to the base layer 1 through the glue spray nozzle at a line speed of 10-30 m / min, and then dry it in the drying curing device 3 at a temperature of 120-200° C. to fix the coating layer 11 on the base layer 1;

[0051] Step 4: Wind the processed cable with a semi-conductive nylon tape, and finally test the electrical properties of the semi-conductive nylon tape product.

[0052] It should be noted that when processing semi-conductive nylon tape for cables, in order to improve production efficiency, a base layer 1 of a specified width is selected to prepare the semi-conductive nylon tape. After the preparation of the semi-conductive nylon tape is completed, it is rolled into bundles, and the semi-conductive nylon tape coil is cut according to usage requirements, and the semi-conductive nylon tape coil is cut into multiple coils of different widths for reuse.

[0053] The semi-conductive nylon tape for cable is processed by the above process. The core of the above process is to evenly coat the coating layer 11 on the surface of the base layer 1. It can be understood that the coating process is to pour the coating layer 11 on the surface of the base layer 1. As the base layer 1 is continuously conveyed, the coating layer 11 on the base layer 1 is smoothed by the glue plate 42. The excess coating layer 11 on the base layer 1 will accumulate on the front side of the glue plate 42. During the process, since the base layer 1 is continuously unwound, the coating layer 11 accumulated on the front side of the glue plate 42 cannot adjust the flow direction. Therefore, in the prior art, the coating layer 11 is not smoothed by the glue plate 42. Partitions are provided on both sides of the plate 42. The design of the partitions can prevent the coating layer 11 accumulated on the front side of the glue-leveling plate 42 from flowing out from the side of the glue-leveling plate 42, thereby avoiding waste of the coating layer 11. In the prior art, the length of the glue-leveling plate 42 and the spacing between the two partitions are both smaller than the width of the base layer 1. If the spacing between the two partitions is larger than the width of the base layer 1, the coating layer 11 will fall on the surface of the guide roller 25, increasing the workload of cleaning the coating layer 11 on the guide roller 25. After the semi-conductive nylon belt is processed, the parts on both sides of the base layer 1 that are not coated with the coating layer 11 are cut. However, in the prior art, the parts of the base layer 1 that do not contain the coating layer 11 are cut and discarded, which will directly lead to waste of materials, not only resulting in increased production costs, but also increasing process complexity, extending the production cycle, reducing production efficiency, and limiting the size specifications of the final product.

[0054] Based on the above implementation and the problems existing in the prior art production, the present invention also provides a preparation device for a semi-conductive water-blocking binding tape containing water-blocking powder, Figures 3 to 5The device comprises a coating mechanism 2 and a drying and curing device 3. The coating mechanism 2 is arranged at the input end of the drying and curing device 3. The coating mechanism 2 comprises a mounting frame 21. A discharging roller 22 and a winding roller 23 are rotatably arranged on the mounting frame 21. A base layer 1 is wound and fixedly arranged on the discharging roller 22. A glue spray head is arranged on the coating mechanism 2. A guide roller 25 is also rotatably arranged on the coating mechanism 2. The guide roller 25 is adapted to the base layer 1. The glue spray head is used to spray the coating layer 11 on the surface of the base layer 1.

[0055] The coating mechanism 2 is provided with a glue spreading mechanism 4, which includes a glue spreading plate 42, the width of which is greater than the width of the base layer 1, and the glue spreading plate 42 is used to scrape the coating layer 11 on the surface of the base layer 1. The coating mechanism 2 is also provided with a glue guiding mechanism 5, which includes a guiding belt 52, which is in contact with the bottom of the base layer 1, and is used to guide the coating layer 11 overflowing from the surface of the base layer 1.

[0056] The base layer 1 with the sprayed coating layer 11 enters the drying and curing device 3 through the rotation transmission of the guide roller 25. The drying and curing device 3 cures the coating layer 11 on the base layer 1 by heating and raising the temperature. The winding roller 23 winds up the base layer 1 by rotating.

[0057] A linear drive 2 is fixedly arranged on the mounting frame 21, and an auxiliary roller 24 is rotatably arranged on the output shaft of the linear drive 2, and the auxiliary roller 24 is adapted to the base layer 1. The drying curing device 3 is heating drying, and the drying method adopted includes but is not limited to infrared heating drying, which is a mature prior art and will not be described in detail here.

[0058] It should be noted that the glue coating nozzle is arranged on one side of the glue leveling plate 42 and is located above the guide roller 25. The glue coating nozzle is arranged along the width direction of the base layer 1, and the glue spraying port of the glue coating nozzle is arranged toward the base layer 1. The glue coating nozzle is fixedly connected to a delivery pipe, and the end of the delivery pipe away from the glue coating nozzle is fixedly connected to a pump. The feed end of the pump is fixedly connected to a storage box, and the storage box contains adhesive, which is the raw material of the coating layer 11. The above components constitute a complete coating system. As a mature existing technology, the coating system will not be described in detail here.

[0059] It should also be noted that the second linear drive is configured as a cylinder, and the auxiliary roller 24 is rotatably configured on the output shaft of the cylinder. The movement of the cylinder output shaft drives the auxiliary roller 24 to move vertically. The movement of the auxiliary roller 24 can adjust the tension of the base layer 1 during transportation.

[0060] In this embodiment, the guide belt 52 is sleeved on the guide roller 25, and the base layer 1 to be processed is placed on the unwinding roller 22, so that the base layer 1 is wound around the auxiliary roller 24 and the guide roller 25. When the base layer 1 passes through the guide roller 25, the edge of the base layer 1 covers the guide belt 52. When in use, the base layer 1 is unwound by the rotation of the unwinding roller 22 and the rotation of the guide roller 25. During the unwinding process of the base layer 1, the adhesive, that is, the coating layer 11, is sprayed on the surface of the base layer 1 through the glue spray nozzle. When the base layer 1 coated with the coating layer 11 passes under the glue leveling plate 42, the uneven thickness and the excess coating layer 11 will be evenly The glue plate 42 is smoothed. Since the width of the glue plate 42 is greater than the width of the base layer 1, the coating layer 11 can be completely coated in the width direction of the base layer 1. The coating layer 11 with more accumulation on the front side of the glue plate 42 will flow along the length direction of the glue plate 42 to both sides of the glue plate 42. Since the guide belt 52 is provided, the excess guide belt 52 will temporarily stay on the guide belt 52. Compared with the prior art, when processing the semi-conductive nylon belt for cables, not only can the coating layer 11 be completely and evenly coated on the surface of the base layer 1, but also the flow of adhesive liquid can be prevented from contaminating the guide roller 25.

[0061] Embodiment 3

[0062] Refer to the instruction manual Figures 6 to 9 , which is different from the above-mentioned embodiment, when the excess adhesive flows to the surface of the guide belt 52, in order to avoid excessive adhesive accumulation on the surface of the guide belt 52, causing the adhesive to adhere to the lower side of the base layer 1, specifically, the glue guide mechanism 5 also includes a transmission roller 51, the transmission roller 51 is rotatably set on the mounting frame 21, and the guide belt 52 is transmission-set on the guide roller 25 and the transmission roller 51. An inclined portion 521 is fixedly set on the guide belt 52, and a conical wheel 53 is fixedly set on the transmission roller 51 and the guide roller 25, and the inclined portion 521 is transmission-connected with the conical wheel 53. A side plate 54 is fixedly set on the mounting frame 21, and an adapting hole is opened on the side plate 54, and the inclined portion 521 is in contact with the inner wall of the adapting hole. A baffle 55 is fixedly set on the side plate 54, and the bottom of the baffle 55 is adapted to the inclined portion 521, and the top of the baffle 55 is in contact with the bottom of the glue-distributing plate 42.

[0063] It should be noted that a curved plate is fixedly provided on one side of the baffle 55 away from the side plate 54 , and the curved plate fits the guide roller 25 to prevent the adhesive from flowing to the back of the base layer 1 through the angle between the base layer 1 and the guide roller 25 .

[0064] It should also be noted that when too much adhesive is accumulated on the base layer 1 and flows to both sides along the length direction of the glue leveling plate 42, the inclined portion 521 is provided. The inclined portion 521 can guide the excess adhesive to prevent the adhesive from accumulating at the edge of the base layer 1 and entering the back side of the base layer 1, and the inclined portion 521 can be synchronously transported with the rotation of the guide roller 25. The provided guide roller 25 can ensure that the excess adhesive on the inclined portion 521 is always located in front of the baffle 55.

[0065] Embodiment 4

[0066] Refer to the instruction manual Fig.10 and Fig.11 , which is different from the above technical solution, as the processing of the base layer 1 continues, more and more adhesive is accumulated on the front side of the baffle 55 on the inclined portion 521. In order to improve the utilization rate of the adhesive and avoid waste, and prevent the excessive accumulation of adhesive from flowing out and causing pollution, specifically, the area between the front side of the baffle 55 and the inclined portion 521 is set as a buffer zone, and the mounting frame 21 is provided with a glue collection mechanism 6, which includes a collection pipe 61, which is fixedly arranged on the side plate 54 and is located in the buffer zone. The glue collection mechanism 6 also includes a guide seat 62, which is fixed on the side plate 54, and an auxiliary plate 63 is slidably arranged in the guide seat 62, and the auxiliary plate 63 is slidably arranged with the side plate 54, and the bottom of the auxiliary plate 63 is in contact with the inclined portion 521.

[0067] It should be noted that the collecting pipe 61 is fixedly connected to a pump, and the end of the pump away from the collecting pipe 61 is fixedly connected to the storage box, which is conducive to the recycling of adhesive accumulated in the buffer zone. A guide rod is fixedly arranged in the guide seat 62, a connecting seat is fixedly arranged on the auxiliary plate 63, the connecting seat is slidably sleeved in the guide rod, a spring is fixedly arranged between the inner wall of the guide seat 62 and the auxiliary plate 63, a pull rope is fixedly arranged on the connecting seat, and a cylinder is fixedly arranged on the side plate 54, and the end of the pull rope away from the connecting seat is fixedly arranged on the output shaft of the cylinder.

[0068] It should also be noted that with the continuous processing of the base layer 1, more and more adhesive accumulates in the buffer zone, and the pump is started. The pump transports the adhesive accumulated in the buffer zone to the storage box through the collecting pipe 61. When the processing of the base layer 1 is stopped, the inclined portion 521 is no longer transmitted. At this time, the cylinder and the pump are started, and the movement of the cylinder output shaft drives the auxiliary plate 63 to move toward the baffle 55. The bottom of the auxiliary plate 63 is always in contact with the surface of the inclined portion 521. The movement of the auxiliary plate 63 reduces the space of the buffer zone, thereby further improving the efficiency of the collecting pipe 61 in extracting the adhesive accumulated in the buffer zone.

[0069] Refer to the instruction manual Figures 3 to 5In order to be able to adjust the thickness of the coating layer 11 according to processing requirements, specifically, the glue spreading mechanism 4 also includes a support seat 41, the support seat 41 and the mounting frame 21 are rotatably set, the glue spreading plate 42 is fixedly set on the support seat 41, and a linear driver 43 is fixedly set on the mounting frame 21, and the output shaft of the linear driver 43 is rotatably set with the support seat 41.

[0070] It should be noted that the linear drive 43 is configured as a cylinder, the cylinder is fixedly mounted on the mounting frame 21, and the output shaft of the cylinder is rotatably mounted on the support seat 41.

[0071] It should also be noted that, when the linear drive 43 is started, since the support seat 41 is rotatably set on the mounting frame 21, and the output shaft of the linear drive 43 is rotatably set with the support seat 41, the movement of the output shaft of the linear drive 43 pushes the support seat 41 to rotate on the mounting frame 21, and the rotation of the support seat 41 can adjust the distance between the glue leveling plate 42 and the base layer 1. When the base layer 1 passes under the glue leveling plate 42, the effect of adjusting the thickness of the coating layer 11 is achieved.

[0072] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
