DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-3 , the present utility model provides a technical solution: a knife-edge type glue discharging and scraping device, including an upper scraper 1, a lower scraper 2, a glue valve 3 and an internal control blade 4. A plurality of glue valves 3 are arranged above the upper scraper 1 and communicate with the upper scraper 1. An internal control passage 11 and a glue discharging port 12 are provided between the upper scraper 1 and the lower scraper 2, and one side of the internal control passage 11 communicates with the glue discharging port 12.

[0020] The glue valve 3 includes a valve body 31, an upper inner spring 32 and a glue control valve member. The valve body 31 is provided with a glue inlet cavity 311, a control cavity 312, an upper air inlet hole 313, a lower air inlet hole 314 and a glue inlet hole 315. The glue inlet cavity 311 and the control cavity 312 are arranged inside the valve body 31. The glue inlet cavity 311 is arranged below the control cavity 312. The inner diameter of the control cavity 312 is larger than that of the glue inlet cavity 311. The lower air inlet hole 314 communicates with the control cavity 312. The glue inlet cavity 311 communicates with the glue inlet hole 315. The glue control valve member is provided with a limit slider 341 and a glue control shaft 342. The limit slider 341 is limited to slide in the control cavity 312. The outer edge of the limit slider 341 abuts against the cavity wall of the control cavity 312 to prevent the glue in the glue inlet cavity 311 from entering above the limit slider 341. Moreover, since the inner diameter of the control cavity 312 is larger than that of the glue inlet cavity 311, the limit slider 341 will not enter the glue inlet cavity 311 during the moving process. A glue outlet channel 317 is arranged at the bottom of the glue inlet cavity 311. The bottom of the glue outlet channel 317 is provided with a tapered opening. The upper end of the glue control shaft 342 is fixedly connected with the limit slider 341, and the lower end is provided with a tapered head that matches the shape of the tapered opening. There is a gap between the glue outlet channel 317 and the glue control shaft 342. The glue outlet channel 317 communicates with the glue inlet cavity 311 and the inner control channel 11. When the tapered head of the glue control shaft 342 is connected with the tapered opening, the glue in the glue inlet cavity 311 cannot flow into the inner control channel 11 from the glue outlet channel 317, and the limit slider 341 will also block the communication position between the lower air inlet hole 314 and the control cavity 312.

[0021] An air inlet channel 316 communicating with the control cavity 312 is arranged above the control cavity 312. The air inlet channel 316 communicates with the upper air inlet hole 313. The valve body 31 is provided with an adjusting screw 318 abutting against the upper end of the limit slider 341 and an adjusting nut 319 threadedly connected with the adjusting screw 318. The adjusting screw 318 passes through the air inlet channel 316 and abuts against the limit slider 341. There is a gap between the adjusting screw 318 and the air inlet channel 316. The air entering from the upper air inlet hole 313 can reach the control cavity 312. The adjusting nut 319 is fixedly arranged on the outer wall of the valve body 31 and communicates with the air inlet channel 316.

[0022] By adjusting the gas volumes of the upper air inlet hole 313 and the lower air inlet hole 314, the limit slider 341 is lifted and lowered within the control chamber 312, that is, the glue volumes contained in the glue inlet chamber 311 and the control chamber 312 are controlled. Moreover, the clearance range between the glue control shaft 342 and the glue outlet channel 317 is controlled. The larger the clearance range is, the slower the glue outlet speed of the glue outlet channel 317 is. When the conical head of the glue control shaft 342 is connected to the conical opening of the glue outlet channel 317, the glue in the glue inlet chamber 311 cannot flow into the internal control channel 11 from the glue outlet channel 317. Since the gas flow rate will fluctuate, the position of the limit slider 341 within the control chamber 312 can also be adjusted by rotating the adjusting nut 319 to limit the floating range of the limit slider 341 within the control chamber 312.

[0023] The upper inner spring 32 is arranged within the control chamber 312 and abuts against the upper surface of the limit slider 341, and the upper inner spring 32 applies a downward elastic force to the limit slider 341.

[0024] The internal control blade 4 is limited to slide within the internal control channel 11. The outer wall of the internal control blade 4 is shaped to fit the inner wall of the internal control channel 11. The internal control blade 4 can be pushed manually or by a motor or a cylinder. The internal control blade 4 can be provided with one inserted into the internal control channel 11 from either end of the upper scraping blade 1, or two inserted into the internal control channel 11 from both ends of the upper scraping blade 1 respectively. The internal control blade 4 can block the glue outlet channel 317 so as to prevent the glue valve 3 from discharging glue, and finally adjust the glue outlet width to adapt to the use of coils with different widths.

[0025] Finally, it should be noted that the above are only the preferred examples of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
