Description

Technical Field

[0001] The present application relates to the technical field of water-blocking tape processing, and in particular to a water-blocking tape powdering device. Background Art

[0002] Optical cables and electric cables are important transmission devices in the fields of power supply and communication. Most of the optical cables and electric cables are laid underground or exposed to the external environment. It is inevitable that optical cables and electric cables are affected by humid air. In order to prevent moisture erosion from affecting the transmission quality of the cables, it is necessary to wrap a layer of water-blocking tape outside the cables. Existing water-blocking tapes generally consist of a reinforcing layer and a water-blocking layer. The water-blocking layer is a layer of water-blocking powder adhered to the surface of the reinforcing layer via an adhesive.

[0003] However, the adhesiveness of the water-blocking powder itself is poor. Existing water-blocking powder powdering devices usually use a powdering roller for pressing powdering. When the water-blocking powder already coated on the water-blocking surface comes into contact with the rotating powdering roller again, due to physical adsorption, the water-blocking powder is easily adsorbed on the surface of the powdering roller, resulting in uneven distribution of the water-blocking powder on the surface of the water-blocking tape, leading to uneven waterproof effects of the water-blocking tape and seriously affecting the water-blocking effect of the water-blocking tape, with obvious deficiencies. Utility Model Content

[0004] In order to improve the uniformity of the water-blocking powder on the water-blocking tape, the present application provides a water-blocking tape powdering device.

[0005] The water-blocking tape powdering device provided by the present application adopts the following technical solution:

[0006] A water-blocking tape powdering device includes a workbench, on which a conveyor belt for conveying the water-blocking tape and a housing are arranged. The housing is provided with a feed inlet and a discharge outlet. A mixing tank is arranged on one side of the workbench close to the feed inlet. The mixing tank stores water-blocking powder and solid glue powder. A mixing assembly is arranged in the mixing tank. A powder discharging assembly is arranged in the housing. The powder discharging assembly includes a powder feeding pipe communicated with the inside of the mixing tank. The powder feeding pipe is arranged inside the housing and is communicated with a powder discharging pipe. A plurality of powder discharging nozzles are equidistantly and uniformly arranged in the length direction of the powder discharging pipe. The powder discharging direction of the powder discharging nozzles is set towards the water-blocking tape.

[0007] By adopting the above technical solution, when powdering the water-blocking tape, first, the solid glue powder in the mixing tank is mixed evenly with the water-blocking powder by the mixing assembly to obtain a mixed powder of the water-blocking powder and the solid glue powder. This mixed powder moves to the powder discharging nozzles through the powder feeding pipe and the powder discharging pipe and is finally evenly sprayed onto the water-blocking tape. The adhesiveness of the water-blocking powder after being mixed with the solid glue powder is significantly improved. Therefore, the water-blocking powder coated on the surface of the water-blocking tape is not easy to fall off, the uniformity of the water-blocking powder on the water-blocking tape is improved, and thus the water-blocking effect of the water-blocking tape is improved.

[0008] Optionally, a powder vibrating assembly is arranged inside the housing. The powder vibrating assembly includes a mounting frame arranged inside the housing. The powder outlet pipe is slidably connected to the mounting frame. A cam is rotatably connected inside the mounting frame. One end of the mounting frame away from the cam is provided with a spring. One end of the spring is connected to the side wall of the mounting frame, and the other end is connected to the powder outlet pipe. A second motor is arranged on the top surface of the housing. The output shaft of the second motor is fixedly connected to the cam. In the initial state, the protruding end of the cam abuts against the end face of the powder outlet pipe, and the spring is compressed.

[0009] By adopting the above technical solution, before the powder outlet pipe discharges powder, the second motor is started to drive the cam to rotate. When the protruding part of the cam gradually approaches the powder outlet pipe, the powder outlet pipe gradually moves towards the direction close to the spring. When the protruding part of the cam gradually moves away from the powder outlet pipe, the pressure on the spring decreases, and the spring drives the powder outlet pipe to move towards the direction away from the spring, thereby realizing the left and right movement of the powder outlet pipe in the mounting frame. During the movement, the powder discharging range of the powder outlet pipe is enlarged, and the continuously moving powder outlet pipe can evenly disperse the buffer powder in the powder outlet pipe, effectively reducing the possibility of the mixed powder caking, thereby further improving the uniformity of the water blocking powder on the water blocking belt.

[0010] Optionally, the stirring assembly includes a main stirring rod and a plurality of auxiliary stirring rods rotatably connected inside the stirring box. The main stirring rod is arranged at the center of the stirring box. The plurality of auxiliary stirring rods are evenly distributed in a circumferential manner on the outer peripheral side of the main stirring rod. A plurality of stirring blades are arranged on both the main stirring rod and the plurality of auxiliary stirring rods. A driving assembly for driving the main stirring rod and the auxiliary stirring rods to rotate synchronously is arranged inside the stirring box.

[0011] By adopting the above technical solution, during stirring, the driving assembly drives the main stirring rod and the plurality of auxiliary stirring rods to rotate synchronously. During the rotation, the stirring blades are driven to stir the mixed powder. The arrangement of the main stirring rod and the auxiliary stirring rods effectively increases the stirring coverage area and reduces the stirring dead corners inside the stirring box, thereby improving the uniformity of the water blocking powder in the solid glue powder, and further improving the uniformity of the water blocking powder on the water blocking belt.

[0012] Optionally, the driving assembly includes a first motor arranged on the stirring box. The output shaft of the first motor is fixedly connected to the main stirring rod. A driving gear is fixedly sleeved on the main stirring rod. A driven gear corresponding to each auxiliary stirring rod is meshed with the driving gear. The driven gear is fixedly connected to the auxiliary stirring rod. A toothed ring meshing with the plurality of driven gears is arranged on the inner peripheral side wall of the stirring box.

[0013] By adopting the above technical solution, during stirring, the first motor is started, the first motor drives the main stirring rod to rotate, the main stirring rod drives the driving gear to rotate, and the driving gear drives a plurality of engaged driven gears to rotate, thereby realizing the synchronous rotation of a plurality of auxiliary stirring rods. At the same time, under the setting of the gear ring, the driven gear will move circumferentially along the gear ring during rotation, and the movement of the driven gear drives a plurality of auxiliary stirring rods to move along the inner circumferential side wall of the stirring tank, thereby further expanding the stirring range of the stirring assembly, further improving the stirring effect of the stirring assembly, and improving the uniformity of the water-blocking powder in the solid glue powder.

[0014] Optionally, a drying assembly is arranged on one side of the housing close to the discharge port. The drying assembly includes a hot air blower arranged on the housing. The air outlet end of the hot air blower is communicated with an air outlet pipe. The air outlet pipe is arranged inside the housing and the air outlet direction is towards the water-blocking belt.

[0015] By adopting the above technical solution, when the conveyor belt drives the water-blocking belt to move below the air outlet of the air outlet pipe, under the action of hot air, the water-blocking powder is gradually dried on the surface of the water-blocking belt, and the excess water on the surface of the water-blocking belt and in the water-blocking powder is removed, thereby avoiding the possibility of partial caking caused by the water-blocking powder absorbing water and expanding. Thereby further improving the uniformity of the water-blocking powder on the surface of the water-blocking belt. At the same time, the drying assembly can make the water-blocking powder directly contact the water-blocking belt, enhancing the adhesion of the water-blocking powder on the surface of the water-blocking belt.

[0016] Optionally, a leveling assembly is arranged between the drying assembly and the powder discharging assembly. The leveling assembly includes a cylinder arranged on the top surface of the housing. The output shaft of the cylinder is fixedly connected with a scraper. The scraper is vertically slidably connected inside the housing. The bottom end of the scraper abuts against the water-blocking powder on the water-blocking belt.

[0017] By adopting the above technical solution, when the conveyor belt drives the water-blocking belt to pass by the scraper, the bottom surface of the scraper contacts the surface of the water-blocking belt. During the transmission of the water-blocking belt, the scraper moves relative to the water-blocking belt, thereby leveling the uneven water-blocking powder on the surface of the water-blocking belt. At the same time, the operator can adjust the distance between the scraper and the water-blocking belt through the cylinder, thereby adjusting the thickness of the water-blocking powder on the water-blocking belt to ensure the best water-blocking effect of the water-blocking powder on the surface of the water-blocking belt. Such a setting further improves the uniformity of the water-blocking powder on the surface of the water-blocking belt, and at the same time improves the water-blocking effect of the water-blocking belt.

[0018] Optionally, a wetting assembly is arranged on one side of the housing close to the feed port. The wetting assembly includes a rotating roller rotatably connected inside the housing. A sponge layer is sleeved on the outer surface of the rotating roller. The sponge layer abuts against the surface of the water-blocking belt. A water tank is arranged on the housing. A water outlet pipe is communicated with the water tank. A first electromagnetic valve is arranged on the water outlet pipe. The water outlet direction of the water outlet pipe is towards the sponge layer.

[0019] By adopting the above technical solution, when applying powder to the water-blocking tape, the first solenoid valve is opened, and the water in the water tank flows through the water outlet pipe to the sponge layer. Under the rotation of the rotating roller, the surface of the sponge layer is evenly wetted by water absorption. When the wetted sponge layer contacts the water-blocking tape, the surface of the water-blocking tape is evenly wetted. After the water-blocking powder contacts the wet surface of the water-blocking tape, it is more likely to adhere to the surface of the water-blocking tape, thereby reducing the probability of the water-blocking powder falling off, further improving the uniformity of the water-blocking powder. At the same time, the method of wetting the surface of the water-blocking tape with the sponge layer effectively improves the uniformity of water on the surface of the water-blocking tape, and avoids the possibility that water accumulates concentratedly on the surface of the water-blocking tape and causes the water-blocking powder to absorb water and agglomerate.

[0020] Optionally, a second solenoid valve is provided on the powder outlet pipe.

[0021] By adopting the above technical solution, the setting of the second solenoid valve realizes the control of the powder outlet speed of the powder outlet pipe, and avoids the situation that the powder outlet speed of the powder outlet pipe is too fast and causes excessive accumulation of the water-blocking powder on the surface of the water-blocking tape.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. By setting a stirring assembly and a powder outlet assembly in the present application, the mixing of the solid glue powder and the water-blocking powder is realized through the stirring assembly, and the mixed powder is applied to the surface of the water-blocking tape through the powder outlet assembly. Such a setting significantly improves the adhesion of the water-blocking powder, the water-blocking powder applied to the surface of the water-blocking tape is not easy to fall off, and the uniformity of the water-blocking powder on the water-blocking tape is improved, thereby improving the water-blocking effect of the water-blocking tape;

[0024] 2. By setting a powder shaking assembly in the present application, the left-right reciprocating movement of the powder outlet pipe in the shell is realized through the powder shaking assembly. The shaking assembly expands the contact range between the water-blocking powder and the water-blocking tape, and at the same time, the continuously moving powder outlet pipe can evenly disperse the buffer powder in the powder outlet pipe, effectively reducing the possibility of the mixed powder agglomerating, thereby further improving the uniformity of the water-blocking powder on the water-blocking tape;

[0025] 3. By setting a wetting assembly in the present application, the water-blocking tape is wetted in advance through the wetting assembly. After the water-blocking powder contacts the wet surface of the water-blocking tape, it is more likely to adhere to the surface of the water-blocking tape, thereby reducing the probability of the water-blocking powder falling off and further improving the uniformity of the water-blocking powder.

Detailed implementation manners

[0031] The following will Figures 1-4 describe the present application in further detail.

[0032] The embodiment of the present application discloses a water blocking strip powder applying device.

[0033] Referring to Figure 1 , Figure 2 and Figure 3 , a water blocking strip powder applying device includes a workbench 1 and a housing 2. A conveyor belt 101 for conveying the water blocking strip 01 is rotatably connected to the workbench 1. The housing 2 is fixedly installed on the surface of the workbench 1. Feed inlets 201 and discharge outlets 202 are respectively opened at opposite ends of the housing 2. A wetting component 3, a powder discharging component 4, a leveling component 5 and a drying component 6 are sequentially arranged on the housing 2 along the conveying direction of the water blocking strip 01.

[0034] When the water blocking strip 01 needs to be powdered, the water blocking strip 01 is placed on the conveyor belt 101 on one side of the feed inlet 201. When the conveyor belt 101 drives the water blocking strip 01 to pass through the wetting component 3, the wetting component 3 wets the surface of the water blocking strip 01. When the wetted water blocking strip 01 passes through the powder discharging component 4, the powder discharging component 4 evenly applies the water blocking powder on the surface of the water blocking strip 01. Subsequently, the leveling component 5 levels the uneven water blocking powder on the surface of the water blocking strip 01, and the drying component 6 dries the moisture between the water blocking strip 01 and the water blocking powder, accelerating the forming of the water blocking strip 01. Finally, the water blocking strip 01 with the water blocking powder attached is obtained from the discharge outlet 202.

[0035] Referring to Figure 1 , Figure 2 andFigure 3 , the wetting component 3 includes a rotating roller 31 arranged on one side of the feed inlet 201 of the housing 2. The rotating roller 31 is rotatably connected inside the housing 2. A sponge layer 32 is sleeved on the outer surface of the rotating roller 31. The sponge layer 32 abuts against the surface of the water blocking belt 01. A water tank 33 is fixedly installed on the top wall of the housing 2 directly above the rotating roller 31. A water outlet pipe 34 communicating with the inside of the housing 2 is arranged on the water tank 33. A first solenoid valve 35 is fixedly installed on the outer surface of the water outlet pipe 34. The water outlet pipe 34 is arranged inside the housing 2 and the water outlet direction is set towards the sponge layer 32.

[0036] Before the conveyor belt 101 is started, the first solenoid valve 35 is opened. The water in the water tank 33 flows to the sponge layer 32 through the water outlet pipe 34. The rotation of the rotating roller 31 drives the sponge layer 32 to absorb water evenly. When the sponge layer 32 absorbs a certain amount of water and remains wet, the first solenoid valve 35 is closed and the conveyor belt 101 is started. When the water blocking belt 01 contacts the wet sponge layer 32, the surface of the water blocking belt 01 is evenly wetted. After the water blocking powder contacts the wet surface of the water blocking belt 01, it is easier to adhere to the surface of the water blocking belt 01, thereby reducing the probability of the water blocking powder falling off, further improving the uniformity of the water blocking powder. At the same time, the method of wetting the surface of the water blocking belt 01 with the sponge layer 32 effectively improves the uniformity of water on the surface of the water blocking belt 01, avoiding the possibility that water accumulates concentratedly on the surface of the water blocking belt 01 and causes the water blocking powder to absorb water and caking.

[0037] Refer to Figure 1 , Figure 2 and Figure 3 , on one side of the housing 2 close to the feed inlet 201, a stirring tank 7 for providing raw materials for the powder discharging component 4 is arranged. The stirring tank 7 is fixedly installed on the top wall of the housing 2. The stirring tank 7 stores water blocking powder and solid glue powder. A stirring component 8 is arranged inside the stirring tank 7. Specifically, the stirring component 8 includes a main stirring rod 81 rotatably connected inside the stirring tank 7 and a plurality of auxiliary stirring rods 82. In this embodiment, the number of the auxiliary stirring rods 82 is four. The main stirring rod 81 is arranged at the central position of the stirring tank 7. The four auxiliary stirring rods 82 are evenly distributed in a circumferential manner on the outer peripheral side of the main stirring rod 81. A plurality of stirring blades 83 are fixedly connected to both the main stirring rod 81 and the auxiliary stirring rods 82. A driving component 9 is arranged inside the stirring tank 7.

[0038] Refer to Figure 1 , Figure 2 and Figure 3, the driving assembly 9 includes a first motor 91 fixedly installed on the top surface of the mixing tank 7. The output shaft of the first motor 91 is fixedly connected to the main stirring rod 81. An active gear 92 is fixedly connected to the main stirring rod 81. Driven gears 93 corresponding to the secondary stirring rods 82 one by one are meshed with the active gear 92. The driven gears 93 are fixedly connected to the rod bodies of the corresponding secondary stirring rods 82. A toothed ring 94 meshed with the four driven gears 93 together is fixedly connected to the inner peripheral side wall of the mixing tank 7. A support block 10 is fixedly connected to the secondary stirring rod 82 near the inner top wall of the mixing tank 7. An annular groove 71 slidably matched with the support block 10 is formed on the inner top wall of the mixing tank 7.

[0039] Before powder application, the first motor 91 is started. The output shaft of the first motor 91 drives the main stirring rod 81 to rotate. The main stirring rod 81 drives the active gear 92 to rotate. The active gear 92 drives the meshed multiple driven gears 93 to rotate, thus realizing the synchronous rotation of the multiple secondary stirring rods 82. At the same time, under the setting of the toothed ring 94, the driven gears 93 will move circumferentially along the toothed ring 94 during rotation. The movement of the driven gears 93 drives the multiple secondary stirring rods 82 to move along the inner peripheral side wall of the mixing tank 7. The settings of the driving assembly 9 and the stirring assembly 8 realize the all-round stirring of the mixed powder inside the mixing tank 7, effectively increasing the stirring coverage area, reducing the stirring dead corners inside the mixing tank 7, thereby improving the uniformity of the water-blocking powder in the solid glue powder, and further improving the uniformity of the water-blocking powder applied on the surface of the water-blocking tape 01.

[0040] Refer to Figure 1 , Figure 2 and Figure 3 , the powder discharging assembly 4 includes a powder feeding pipe 41 communicated with the inside of the mixing tank 7. The powder feeding pipe 41 is vertically arranged inside the housing 2. A second solenoid valve 42 is fixedly installed on the outer surface of the powder feeding pipe 41. The powder discharging end of the powder feeding pipe 41 is communicated with a powder discharging pipe 43 through a corrugated pipe (not shown in the figure). A plurality of powder discharging nozzles 44 are uniformly arranged along the length direction of the powder discharging pipe 43. The powder discharging direction of the powder discharging nozzles 44 is set towards the water-blocking tape 01. A powder shaking assembly 11 is arranged inside the housing 2.

[0041] Refer to Figure 2 , Figure 3 and Figure 4, the powder shaking component 11 includes a mounting frame 111 fixedly installed inside the housing 2. A cam 112 is rotatably connected inside the mounting frame 111. A second motor 113 for driving the cam 112 to rotate is fixedly installed on the top wall of the housing 2. The powder outlet pipe 43 is slidably connected inside the mounting frame 111 through a chute and a slider. A spring 114 is arranged at one end of the mounting frame 111 away from the cam 112. One end of the spring 114 is fixedly connected to the inner side wall of the mounting frame 111, and the other end is fixedly connected to the outer side wall of the powder outlet pipe 43. In the initial state, the protruding end of the cam 112 abuts against the outer side wall of the powder outlet pipe 43, and the spring 114 is compressed by the powder outlet pipe 43.

[0042] Referring to Figure 4 , after the solid glue powder and the water blocking powder in the mixing tank 7 are fully mixed, the second solenoid valve 42 is opened. The mixed powder in the mixing tank 7 moves into the powder outlet pipe 43 through the powder delivery pipe 41 and the connecting pipe. At the same time, the second motor 113 drives the cam 112 to rotate. When the protruding part of the cam 112 gradually approaches the powder outlet pipe 43, the powder outlet pipe 43 gradually moves towards the direction close to the spring 114. When the protruding part of the cam 112 gradually moves away from the powder outlet pipe 43, the pressure on the spring 114 decreases, and the spring 114 drives the powder outlet pipe 43 to move in the direction away from the spring 114, thereby realizing the left and right movement of the powder outlet pipe 43 inside the mounting frame 111. The mixed powder in the powder outlet pipe 43 is evenly sprayed from the left and right moving powder outlet nozzle 44 onto the water blocking belt 01. Such a setting makes the contact range between the water blocking powder and the surface of the water blocking belt 01 larger, and the water blocking powder is more evenly coated on the surface of the water blocking belt 01. At the same time, the adhesiveness after the water blocking powder and the solid glue powder are mixed is significantly improved. Therefore, the water blocking powder coated on the surface of the water blocking belt 01 is not easy to fall off, and the uniformity of the water blocking powder on the water blocking belt 01 is improved, thereby improving the water blocking effect of the water blocking belt 01.

[0043] Referring to Figure 2 , the leveling component 5 includes a cylinder 51 fixedly connected to the top of the housing 2. The output shaft of the cylinder 51 is fixedly connected with a scraper 52. Both ends of the scraper 52 are slidably connected inside the housing 2 through a slider and a chute. The bottom end of the scraper 52 abuts against the water blocking powder on the water blocking belt 01.

[0044] After the water-blocking powder is applied to the surface of the water-blocking tape 01, the surface may be uneven. When the conveyor belt 101 drives the water-blocking tape 01 past the scraper 52, the bottom surface of the scraper 52 contacts the surface of the water-blocking tape 01. During the transmission of the water-blocking tape 01, the scraper 52 moves relative to the water-blocking tape 01, thereby smoothing the uneven water-blocking powder on the surface of the water-blocking tape 01. At the same time, when the thickness of the water-blocking powder on the surface of the water-blocking tape 01 is too thick, the operator can shorten the distance between the scraper 52 and the water-blocking tape 01 through the cylinder 51, thereby reducing the thickness of the water-blocking powder on the water-blocking tape 01 to ensure the best water-blocking effect of the water-blocking powder on the surface of the water-blocking tape 01. Such a setting further improves the uniformity of the water-blocking powder on the surface of the water-blocking tape 01 and at the same time improves the water-blocking effect of the water-blocking tape 01.

[0045] Referring to Figure 2 , the drying assembly 6 includes a hot air blower 61 fixedly installed on the top of the housing 2. The air outlet end of the hot air blower 61 is communicated with an air outlet pipe 62. The air outlet pipe 62 is arranged inside the housing 2 and the air outlet direction is set towards the water-blocking tape 01.

[0046] When the conveyor belt 101 drives the water-blocking tape 01 to move below the air outlet of the air outlet pipe 62, under the action of hot air, the water-blocking powder is gradually dried on the surface of the water-blocking tape 01, and the excess water on the surface of the water-blocking tape 01 and in the water-blocking powder is removed, thereby avoiding the possibility of partial caking caused by the water absorption and expansion of the water-blocking powder, and further improving the uniformity of the water-blocking powder on the surface of the water-blocking tape 01.

[0047] The implementation principle of a powder application device for a water-blocking tape in an embodiment of this application is as follows: When powder needs to be applied to the water-blocking tape 01, the water-blocking tape 01 is placed on the conveyor belt 101 on one side of the feed inlet 201. When the conveyor belt 101 drives the water-blocking tape 01 to pass through the wetting component 3, the wetting component 3 wets the surface of the water-blocking tape 01. At the same time, the stirring component 8 stirs the mixed powder in the stirring tank 7 evenly. When the water-blocking tape 01 moves below the powder discharging component 4, the second solenoid valve 42 is opened, and the mixed powder in the stirring tank 7 moves through the powder feeding pipe 41 and the connecting pipe into the powder discharging pipe 43. At the same time, the second motor 113 drives the cam 112 to rotate. When the protruding part of the cam 112 gradually approaches the powder discharging pipe 43, the powder discharging pipe 43 gradually moves in the direction close to the spring 114. When the protruding part of the cam 112 gradually moves away from the powder discharging pipe 43, the pressure on the spring 114 decreases, and the spring 114 drives the powder discharging pipe 43 to move in the direction away from the spring 114, thus realizing the left and right movement of the powder discharging pipe 43 in the mounting frame 111. The mixed powder in the powder discharging pipe 43 is evenly sprayed from the left and right moving powder discharging nozzles 44 onto the water-blocking tape 01. Such a setting makes the contact range between the water-blocking powder and the surface of the water-blocking tape 01 larger, and the water-blocking powder is more evenly coated on the surface of the water-blocking tape 01. At the same time, the adhesion of the water-blocking powder after being mixed with the solid glue powder is significantly improved. Therefore, the water-blocking powder coated on the surface of the water-blocking tape 01 is not easy to fall off, and the uniformity of the water-blocking powder on the water-blocking tape 01 is improved, thereby improving the water-blocking effect of the water-blocking tape 01.

[0048] The above are all the preferred embodiments of this application. Without restricting the protection scope of this application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
