Description

Technical Field

[0001] The invention relates to the field of cable production, and in particular to a cable coating quality detection device. Background Art

[0002] The cable sheath refers to a sealed sheath wrapped around the outer layer of the cable to prevent moisture from penetrating. Power cables have been widely used to transmit electricity in cities. After the cable sheath is produced and processed, its wear resistance needs to be tested to avoid easy wear of the cable after it is put on the market.

[0003] After searching, the Chinese patent application with the patent publication number CN113138117B discloses a wear resistance detection device for cable production and processing, including an experimental platform, a cable guide mechanism, a cable tensioning mechanism and a transmission mechanism. A set of back plates are vertically constructed on one side of the upper end surface of the experimental platform. Two sets of cable guide mechanisms are symmetrically installed on the upper end surface of the experimental platform. A set of cable tensioning mechanisms is installed in the center of the upper end surface of the experimental platform, and a set of first electric telescopic rods for adjusting the height of the cable tensioning mechanism are installed at the bottom end of the cable tensioning mechanism. The transmission mechanism is installed on the side of the back plate away from the installation position of the cable guide mechanism and the cable tensioning mechanism. The transmission motor is embedded in the middle of the back plate. The transmission mechanism includes a set of transmission rods and clamping bases installed at both ends of the transmission rods. The wear resistance detection device for cable production and processing has a reasonable structure, is easy to assemble and use, and can be conveniently adjusted to adapt to different line lengths. The reciprocating drive realizes efficient wear resistance detection.

[0004] When testing the wear resistance of the cable covering, dust and impurities will adhere to the surface of the cable covering. When the cable covering is being tested, the dust and impurities will cause wear to the cable covering under the action of pressure, thereby interfering with the wear resistance test of the cable covering, thereby causing deviations in the test data of the cable covering.

[0009] Preferably, a winding mechanism is arranged on one side of the outer wall of the top of the fixed seat, and the winding mechanism includes a fixing plate, a rotating rod and a winding roller. The fixing plate is connected to the fixed seat by bolts. The rotating rod is rotatably connected to the fixing plate through a bearing. The winding roller is sleeved on the outer wall of the rotating rod. A motor is connected to one side of the fixing plate by bolts, and the motor is connected to the rotating rod by bolts.

[0010] Preferably, limiting rings are respectively arranged on the two sides of the outer wall of the rotating rod. One of the limiting rings is fixedly connected to the rotating rod. External threads are arranged on one side of the outer wall of the rotating rod. The other limiting ring is threadedly connected to the external threads. The two limiting rings are located on the two sides of the winding roller.

[0011] Preferably, two connection grooves are formed at the top of the fixed seat, and a tensioning mechanism is arranged between the two connection grooves and the connection port. The tensioning mechanism is located between the winding mechanism and the wear-resistant detection mechanism.

[0014] Preferably, a guiding mechanism is arranged between the fixed seat and the support plate, and the guiding mechanism is composed of a guide rail and a guide block. The guide rail and the guide block are slidably connected. The guide rail is fixedly connected to the fixed seat, and the guide block is bolted to the support plate.

[0015] The beneficial effects of the present invention are as follows:

[0016] Through the provided dust removal mechanism, when detecting the abrasion resistance of the cable coating layer, the abrasion resistance detection mechanism will deflect to one side under the pulling of the cable coating layer. When the elastic force of the second spring is greater than the pulling force of the cable coating layer on the abrasion resistance detection mechanism, at this time, the abrasion resistance detection mechanism will reset under the action of the elastic force of the second spring. The reciprocating swing of the abrasion resistance detection mechanism can increase the acting force of the abrasion resistance detection mechanism on the cable coating layer, thereby facilitating the improvement of the quality detection effect of the equipment on the cable coating layer. During this period, when the abrasion resistance detection mechanism moves to one side under the elastic force of the second spring, at this time, the sliding plate will squeeze the first air cushion, and the gas inside the first air cushion will be transported to the inside of the first air bag through the connecting pipe after being squeezed. The first air bag will bulge due to the input of gas. At this time, the bulging first air bag can push one side of the swing plate to deflect downward, and the other side of the swing plate will deflect upward. At this time, when the other side of the swing plate deflects upward, it will drive the cable coating layer to move upward, thereby increasing the contact force between the cleaning brush and the cable coating layer, and further improving the cleaning effect of the cleaning brush on the cable coating layer, so as to facilitate the treatment of the dust adhered to the cable coating layer, prevent the dust and impurities from causing abrasion to the cable coating layer under the action of pressure, thereby interfering with the abrasion resistance detection of the cable coating layer, and further causing deviation in the detection data of the cable coating layer. When the elastic force of the fourth spring is greater than the pushing force of the first air bag on the swing plate, the swing plate will reset under the action of the fourth spring. At this time, the contact force between the cable coating layer and the cleaning brush will decrease. Repeating this cycle, the reciprocating swing of the swing plate can clean the surface of the cable coating layer and at the same time can process the dust debris adhered to the cleaning brush through the swing, preventing the dust debris from adhering to the cleaning brush and interfering with the cleaning of the cable coating layer;

[0017] Through the provided tensioning mechanism, when detecting the abrasion resistance of the cable coating layer, the abrasion resistance detection mechanism will deflect to one side under the pulling of the cable coating layer. At this time, the sliding plate will squeeze the second air cushion, and the gas inside the second air cushion will be transported to the inside of the second air bag through the conduit. At this time, the two second air bags will drive the two sliders to slide to one side, so that the two restraint plates are misaligned, and further, the misalignment between the two restraint plates can facilitate the improvement of the tension of the cable coating layer, so as to facilitate the winding treatment of the cable coating layer after detection, preventing the cable coating layer from being too loose during winding, thereby affecting the winding of the cable coating layer;

[0018] Through the provided limiting mechanism, the present invention can limit the cable coating layer located below the winding roller, facilitating the winding process of the cable coating layer, preventing the cable coating layer from sagging during winding, and thus affecting the winding of the cable coating layer. In addition, since the height of the blades gradually decreases from left to right, the cable coating layer will slide to one side under the guidance of the blades, so that the cable coating layer is evenly wound on the surface of the winding roller, preventing the cable coating layer from piling up during winding and affecting the winding of the cable coating layer.

Embodiment Example

[0027] Referring to Figures 1-6 , a cable coating quality detection device, including a fixed seat 1, a wear-resistant detection mechanism 2 is arranged on the top of the fixed seat 1, and the wear-resistant detection mechanism 2 includes two support seats 21, a frame 26 and two detection tables 27. Connection ports 23 are opened at positions near the top on one side of the two support seats 21, and sliding plates 22 are slidably connected to the inner walls of the two connection ports 23. Second springs 24 are connected between the two sides of the two sliding plates 22 and the connection ports 23 by bolts. Support blocks 25 are connected to one side of the two sliding plates 22 by bolts, and the support blocks 25 are connected to the frame 26 by bolts. One of the detection tables 27 is connected to the bottom inner wall of the frame 26 by bolts, and a plurality of third springs 28 are connected between the other detection table 27 and the top inner wall of the frame 26 by bolts. A plurality of detection grooves 29 with different sizes are opened on the opposite sides of the two detection tables 27, and the upper and lower detection grooves 29 correspond to each other. A plurality of friction blocks are arranged on the inner wall of the detection groove 29. A threaded hole is opened on the top of the frame 26, and a limiting bolt 30 is threadedly connected to the inner wall of the threaded hole. The bottom of the limiting bolt 30 contacts the top of one of the detection tables 27. A dust removal mechanism 7 is arranged between the top of the fixed seat 1 and the connection port 23.

[0028] On the basis described above, the dust removal mechanism 7 includes two fixed brackets 32, a swing plate 34, a connecting block 33, a connecting frame 38, a cleaning brush 39, a first air cushion 40 and a first air bag 36. The fixed bracket 32 is bolted to the fixed seat 1. The swing plate 34 is rotatably connected to the fixed bracket 32 through a bearing. The two sides of the connecting block 33 are bolted to the two sides of the fixed bracket 32. A fourth spring 35 is bolted between the swing plate 34 and the connecting block 33. The two sides of the connecting block 33 are bolted to the connecting frame 38. The bottom of the connecting frame 38 is fixedly connected to the cleaning brush 39. Support frames 37 are bolted to both sides of the outer wall of the connecting block 33. The first air bag 36 is located between the support frame 37 and the swing plate 34. The first air cushion 40 is located between one side of the sliding plate 22 and the connection port 23. The first air cushion 40 is made of a hollow elastic material. A connecting pipe 41 is provided between the first air cushion 40 and the first air bag 36. When detecting the abrasion resistance of the cable coating, the abrasion resistance detection mechanism 2 will deflect to one side under the pulling of the cable coating. When the elastic force of the second spring 24 is greater than the pulling force of the cable coating on the abrasion resistance detection mechanism 2, at this time, the abrasion resistance detection mechanism 2 will be reset under the action of the elastic force of the second spring 24. The reciprocating swing of the abrasion resistance detection mechanism 2 can increase the acting force of the abrasion resistance detection mechanism 2 on the cable coating, so as to facilitate improving the quality detection effect of the equipment on the cable coating. During this period, when the abrasion resistance detection mechanism 2 moves to one side under the elastic force of the second spring 24, at this time, the sliding plate 22 will squeeze the first air cushion 40, and the gas inside the first air cushion 40 will be transported to the inside of the first air bag 36 through the connecting pipe 41 after being squeezed. The first air bag 36 will bulge due to the input of gas. At this time, the bulging first air bag 36 can push one side of the swing plate 34 to deflect downward, and the other side of the swing plate 34 will deflect upward. At this time, when the other side of the swing plate 34 deflects upward, it will drive the cable coating to move upward, so that the contact force between the cleaning brush 39 and the cable coating increases, thereby improving the cleaning effect of the cleaning brush 39 on the cable coating, facilitating the treatment of the dust adhered to the cable coating, preventing the dust and impurities from causing abrasion to the cable coating under the action of pressure, thus interfering with the abrasion resistance detection of the cable coating, and further causing deviation of the detection data of the cable coating. When the elastic force of the fourth spring 35 is greater than the thrust of the first air bag 36 on the swing plate 34, the swing plate 34 will be reset under the action of the fourth spring 35. At this time, the contact force between the cable coating and the cleaning brush 39 will decrease. Repeating this process, the reciprocating swing of the swing plate 34 can clean the surface of the cable coating and at the same time can remove the dust and debris adhered to the cleaning brush 39 by swinging, preventing the dust and debris from adhering to the cleaning brush 39 and interfering with the cleaning of the cable coating.

A motor 11 is connected to one side of the fixing plate 8 by bolts, and the motor 11 is connected to the rotating rod 9 by bolts.

[0031] On the basis described above, limiting rings 12 are arranged on both sides of the outer wall of the rotating rod 9. One of the limiting rings 12 is fixedly connected to the rotating rod 9. External threads 13 are formed on one side of the outer wall of the rotating rod 9. The other limiting ring 12 is threadedly connected to the external threads 13. The two limiting rings 12 are located on both sides of the winding roller 10. Embodiment

The second air drums are located between the connection grooves 3 and the sliders 45. The second air cushions 42 are located between the other side of the sliding plate 22 and the connection ports 23. The second air cushions 42 are made of a hollow elastic material. A conduit 43 is arranged between the second air cushions 42 and the second air drums. Constraint openings 46 are formed at positions close to the top on one side of the two constraint plates 44. When detecting the wear resistance of the cable coating layer, the wear resistance detection mechanism 2 will deflect to one side under the pulling of the cable coating layer. At this time, the sliding plate 22 will squeeze the second air cushions 42, and the gas inside the second air cushions 42 will be transported to the inside of the second air drums through the conduit 43.
