Technical Field
[0001] The utility model relates to the technical field of coating machines, in particular to a quantitative feeding device for a coating machine. Background Technique
[0002] The coating process is an important processing technology for improving the surface performance of materials. During the production process of tapes, coating is an indispensable process. When a coating machine is working, a feeding device is often used. However, most of the existing feeding devices have differences in the spraying amount during spraying, which easily causes uneven spraying of the coating machine, resulting in poor feeding effect of the glue solution. Moreover, the excess glue solution on the coating roller is easily affected by temperature during recovery, making the glue solution easily condense into lumps due to temperature reduction, thus blocking the pipeline. Content of the Utility Model
[0003] In view of this, the utility model provides a quantitative feeding device for a coating machine, which can quantitatively spray the glue solution during feeding, and can continuously reciprocate the spray head during spraying, making the glue solution spray more evenly. At the same time, a fan blows hot air into the inner part of the shell, so that the temperature inside the shell is kept as constant as possible, improving the feeding effect of the glue solution.
[0004] The technical solution is: a quantitative feeding device for a coating machine, including a shell, a coating roller, a conveying roller, a slide rail, an electric slider, a pumping device, a guiding pipe, a support, a glue solution tank, a one-way valve, a sensor, a spray head, a scraping plate, a blanking frame and a fan. One side of the upper part of the shell is rotatably connected with a coating roller and a conveying roller, the coating roller and the conveying roller are in contact. On the other side of the upper part of the shell, there is a slide rail, and both sides of the slide rail are slidably connected with electric sliders. On the upper parts of the two electric sliders, there are pumping devices. On both electric sliders, there are guiding pipes. The two guiding pipes are symmetrically arranged. The guiding pipe passes through the electric slider and is communicated with the pumping device. There is a support on the upper part of the shell, and the support is in contact with the two guiding pipes. There is a glue solution tank in the lower part of the shell. The two guiding pipes are both located inside the glue solution tank. One-way valves are arranged on the upper parts of the two guiding pipes. The upper parts of the two guiding pipes are both directly above the coating roller. Sensors are arranged on the upper parts of the two guiding pipes. The sensors are electrically connected with the pumping device. Spray heads are arranged on the upper parts of the two guiding pipes. The spray heads are communicated with the guiding pipes. There is a scraping plate in the upper part of the shell. The scraping plate is in contact with the coating roller. The scraping plate is inclined. There is a blanking frame in the upper part of the shell. There is a fan on one side of the inner part of the shell far away from the guiding pipe.
[0005] Further, the blanking frame is inclined, the blanking frame is located directly below the scraping plate, and an inclined pipe is arranged at the lower part of the blanking frame. The inclined pipe at the lower part of the blanking frame is located inside the glue solution tank.
[0006] The beneficial effects are as follows: First, manually start two electric sliders, two pumps, sensors, and fans. The pumps will draw the glue liquid in the glue liquid tank along the material guiding pipe. The two nozzles will continuously spray equal amounts of glue liquid evenly on the coating roller. The scraper will scrape off the residual glue liquid on the coating roller. The fan will blow hot air into the housing. This can perform quantitative spraying of the glue liquid during feeding, and can continuously reciprocate the nozzles during spraying, making the glue liquid spraying more uniform, thus making the feeding effect of the glue liquid better. At the same time, the fan will blow hot air into the housing, keeping the temperature inside the housing as constant as possible, thereby avoiding the glue liquid from coagulating into lumps due to temperature reduction and further blocking the material guiding pipe.

Detailed Embodiment
[0012] The present utility model will be further described below with reference to the drawings and embodiments.
[0013] Embodiment 1: A quantitative feeding device for a coating machine, as Figures 1 - 4As shown in the figure, it includes a housing 1, a coating roller 2, a conveying roller 3, a slide rail 4, an electric slider 5, a suction pump 6, a guide pipe 7, a support 8, a glue tank 9, a check valve 10, a sensor 11, a spray head 12, a scraper 13, a blanking frame 14 and a fan 15. On one side of the upper part of the housing 1, the coating roller 2 and the conveying roller 3 are rotatably connected. The coating roller 2 and the conveying roller 3 are in contact. On the other side of the upper part of the housing 1, the slide rail 4 is welded. Both sides of the slide rail 4 are slidably connected with the electric slider 5. Suction pumps 6 are arranged on the upper parts of the two electric sliders 5. Guide pipes 7 are connected to the two electric sliders 5 through flanges. The two guide pipes 7 are symmetrically arranged. The guide pipe 7 passes through the electric slider 5 and is communicated with the suction pump 6. The upper part of the housing 1 is connected with the support 8 by bolts. The support 8 is in contact with the two guide pipes 7. The support 8 is used to support the two guide pipes 7. The lower part of the inner part of the housing 1 is welded with the glue tank 9. The two guide pipes 7 are both located inside the glue tank 9. Check valves 10 are arranged on the upper parts of the two guide pipes 7. The upper parts of the two guide pipes 7 are both directly above the coating roller 2. Sensors 11 are arranged on the upper parts of the two guide pipes 7. The sensor 11 is electrically connected with the suction pump 6. Spray heads 12 are arranged on the upper parts of the two guide pipes 7. The spray head 12 is communicated with the guide pipe 7. The upper part of the inner part of the housing 1 is connected with the scraper 13 by rivets. The scraper 13 is in contact with the coating roller 2. The scraper 13 is inclined. The blanking frame 14 is welded on the upper part of the inner part of the housing 1. The blanking frame 14 is inclined. The blanking frame 14 is located directly below the scraper 13. An inclined pipe is arranged at the lower part of the blanking frame 14. The inclined pipe at the lower part of the blanking frame 14 is located inside the glue tank 9. A fan 15 is arranged on one side of the inner part of the housing 1 away from the guide pipe 7.
[0014] First, the coating machine is started manually, and the coating machine drives the coating roller 2 and the conveying roller 3 to rotate. Then, the two electric sliders 5, the two pumps 6, the sensor 11 and the fan 15 are started manually. The pump 6 will draw the glue in the glue tank 9 along the guide pipe 7. When the sensor 11 detects that the glue in the guide pipe 7 is pumped to the upper part of the guide pipe 7, the sensor 11 is electrically connected to the pump 6, so that the pump 6 is turned off, and the pump 6 no longer draws glue. At this time, the glue on the upper part of the guide pipe 7 Under the action of the one-way valve 10, the liquid will not flow back into the glue tank 9, the guide pipe 7 is connected with the nozzle 12, so that the nozzle 12 sprays the glue on the upper part of the guide pipe 7, and the nozzle 12 is located just above the coating roller 2. At the same time, the two electric sliders 5 drive the two pumps 6, the two guide pipes 7, the two one-way valves 10, the two sensors 11 and the two nozzles 12 to move back and forth in the direction of approaching or moving away from each other, so that the nozzle 12 sprays the glue evenly just above the coating roller 2. After all the glue in the tube 7 is sprayed, the sensor 11 no longer detects the existence of glue in the guide tube 7, and the pump 6 is turned on again. In this way, the two nozzles 12 will continuously and evenly spray the same amount of glue on the coating roller 2. At the same time, the scraper 13 contacts the coating roller 2, and the scraper 13 will scrape off the residual glue on the coating roller 2, so that the glue drips down along the scraper 13 onto the blanking rack 14. Since the blanking rack 14 is inclined, the glue flows along the inclined direction of the blanking rack 14. The liquid drips into the glue box 9 through the inclined pipe, and the fan 15 blows hot air into the shell 1, so that the glue can be sprayed quantitatively during feeding, and the nozzle 12 can be continuously moved back and forth during spraying, so that the glue is sprayed more evenly, thereby making the glue feeding effect better. At the same time, the fan 15 blows hot air into the shell 1, so that the temperature inside the shell 1 is kept as constant as possible, thereby avoiding the glue from condensing into agglomerates due to temperature reduction as much as possible, thereby clogging the material guide pipe 7.
[0015] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
