Description

Technical Field

[0001] The utility model relates to the technical field of water-blocking tape production equipment, and specifically relates to a powder application device for water-blocking tape production. Background Technique

[0002] At present, optical cables and cables are closely related to our lives. Since most cables are buried underground or exposed to the external environment, it is inevitable to get wet or rained on. Therefore, it is necessary to wrap a layer of water-blocking tape outside the cable to prevent moisture from eroding the cable and affecting the transmission quality of the cable. 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 through an adhesive.

[0003] The existing water-blocking powder application devices apply powder unevenly, resulting in uneven waterproof effects and affecting product quality. During the working process, due to the stress generated by the rotation contact between the water-blocking powder and the powder application roller, some water-blocking powder is adsorbed on the surface of the powder application roller, resulting in uneven distribution of the water-blocking powder in the stagewise spreading setting, and reducing the production quality of the water-blocking tape.

[0004] In the patent document with the publication number of CN218108260U3, a powder application device for water-blocking tape production is disclosed. It uses a vibratable paintbrush to sweep off the water-blocking powder attached to the powder application roller and sprinkle it on the glued water-blocking tape. The constantly vibrating paintbrush can evenly disperse the water-blocking powder brought out of the powder application chamber by the powder application roller at all times, so that the water-blocking powder attached to the water-blocking tape is evenly distributed, ensuring the final quality of the product.

[0005] However, during the use of this powder application device for water-blocking tape production, when adding water-blocking powder into the powder application chamber, if a small amount of water-blocking powder is added at one time, the working efficiency will decrease. If a large amount of water-blocking powder is added at one time, it may cause damage to the powder application roller. Therefore, it is necessary to propose a powder application device for water-blocking tape production that can apply powder evenly. Content of the Utility Model

When the vibration motor 303 vibrates, the water-blocking powder on the surface of the sieve plate 301 can be effectively laid flat. The vibration motor 303 drives the feeding port 3 to vibrate. The water-blocking powder laid on the sieve plate 301 will be evenly laid on the surface of the sieve plate 301 under the vibration of the vibration motor 303, and finally gradually falls through the sieve holes on the sieve plate 301. The vibration motor 303 is arranged on the top of the mounting plate. Embodiment

[0029] On the basis of the second embodiment, a first motor 4, a second motor 5 and a third motor 6 are arranged on one side of the workbench 1. A first conveyor belt 7 and a second conveyor belt 8 are respectively arranged on one side of the second motor 5 and the third motor 6. One end of the workbench 1 is rotatably connected to a rotating shaft 10. A third conveyor belt 9 is arranged on the outer surface of the rotating shaft 10. The bottom of the workbench 1 is fixedly connected to a footrest 11. Two through holes are formed through the front of the powder applying frame 2. One end of the rotating roller 202 and the powder brushing roller 203 respectively penetrate through the two front through holes and are connected to external belt pulleys. The belt pulleys do not contact the outer surface of the powder applying frame 2. A first conveyor belt 7 and a second conveyor belt 8 are respectively arranged between the two belt pulleys and the output ends of the second motor 5 and the third motor 6. A through hole is formed in the back of the powder applying frame 2 and is connected to the other sides of the rotating roller 202 and the powder brushing roller 203.

[0030] Working principle:

[0031] First, after the water-blocking belt is coated with glue, it is conveyed to the bottom of the powder applying frame 2 by the third conveyor belt 9. This device is installed between the gluing device and the drying device.

[0032] Further, after the water-blocking powder is put into the feeding port 3, through the provided powder equalizing mechanism, the vibration motor 303 is started to drive the feeding port 3 to vibrate. The water-blocking powder laid flat on the sieve plate 301 will be evenly laid on the surface of the sieve plate 301 under the vibration of the vibration motor 303, and finally gradually fall through the sieve holes on the sieve plate 301, preliminarily and evenly laying the water-blocking powder, which brings convenience to the subsequent operations.

[0033] Further, when the water-blocking powder falls from the bottom of the sieve plate 301, through the provided powder applying mechanism, the water-blocking powder is laid flat on the surface of the rotating roller 202. Under the action of the second motor 5 and the third motor 6, the rotating roller 202 and the powder brushing roller 203 rotate clockwise and counterclockwise respectively. The water-blocking powder laid flat on the surface of the rotating roller 202 will be gradually brushed off by the powder brushing roller 203 and evenly fall onto the surface of the water-blocking belt.

[0034] Further, the caked water-blocking powder adsorbed on the surface of the rotating roller 202 will be scraped off by the scraping plate 208 and fall into the moving frame 205. Since a first spring 212 is provided on one side of the scraping plate 208, the scraping plate 208 will always be close to the surface of the rotating roller 202, continuously scraping the surface of the rotating roller 202 to ensure that the caked water-blocking powder will not be carried back by the rotating roller 202.

[0035] Furthermore, by pulling the moving handle 206, the moving frame 205 can be pulled out from the powder scattering frame 204 to collect and utilize the scattered powder falling into the moving frame 205.
