Technical Field

[0001] The utility model relates to the technical field of glue liquid recovery, in particular to a glue liquid recovery device for a coating machine. Background Art

[0002] Coating machines are mainly used in the surface coating process production of films, paper, etc. This machine coats the rolled substrate with a layer of glue, paint or ink with specific functions, and rewinds it after drying. When the coating machine is in use, the glue is easy to drip from the coating roller, resulting in waste. However, most of the existing coating machine glue recovery devices cannot filter impurities in the glue well, so that impurities and burrs remain in the glue, resulting in poor glue recovery effect. At the same time, the glue will clump and condense as the temperature drops, which not only easily blocks the pipeline, but also affects the glue recovery efficiency. Utility Model Content

DETAILED DESCRIPTION

[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0012] Example 1: A glue recovery device for a coating machine, such as Figure 1-Figure 4 As shown, it includes a base, a box body, a transmission roller, a coating roller, a partition, a scraper 1, a filter plate, a motor, a rotating shaft, a stirring frame, a scraper 2, an inclined plate, an electric push rod, a push plate, a rotating rod, a spring, a heater, a reflux pipe, a pump and a bracket. A box body is welded on the upper part of the base, and a square hole is opened on the upper part of the box body. A transmission roller and a coating roller are placed on the upper part of the box body. The transmission roller and the coating roller are located above the square hole of the box body. A partition is connected to the inside of the box body by rivets. The partition is used to block the glue liquid. Scraper 1 is welded on the upper part of the partition. Scraper 1 contacts the coating roller. Scraper 1 is arranged at an angle. Two filter plates are clamped inside the box body. Several filter holes are opened on the upper part of the two filter plates. Both filter plates contact the partition. Both filter plates are located directly below the square hole of the box body. A motor is welded on the bottom of the box body. The output shaft of the motor is connected to the rotating shaft by bolts. The rotating shaft passes through the filter plate below. Two stirring frames are provided on the upper part of the rotating shaft. The two stirring frames are linear The top of the box body is provided with a toothed plate, and the toothed plate is connected with the toothed plate by a screw bolt, and the toothed plate is connected with the toothed plate by a screw bolt.

[0013] At first, the two springs are compressed. First, the coating machine is started manually, and the coating machine drives the transmission roller and the coating roller to rotate. Then the motor, electric push rod, pump and heater are started manually. The coating roller contacts the scraper, and the scraper will continuously scrape off the residual glue on the coating roller. The glue drips along the scraper onto the two filter plates. The two filter plates will filter the impurities in the glue in turn, so that the filtered glue drips onto the inclined plate. At the same time, the output shaft of the motor, the electric shaft, rotates, and the shaft drives the two stirring racks and the two scrapers to rotate. The two stirring racks will break up the dripping glue, so that the glue is more evenly distributed on the filter plate below. The two scrapers will scrape off the glue on the filter plate, making the glue better filtered. The telescopic rod of the electric push rod will continuously extend or contract, and the telescopic rod of the electric push rod will drive the push plate to move back and forth along the inclined plate. The push plate contacts the two rotating rods, and the push plate will drive the two rotating rods Continuously moving towards or away from each other, the two springs are constantly reset or compressed, and the two rotating rods will push the glue on the inclined plate down, making the glue slide faster, and the pump will draw the glue in the box out along the return pipe, so that the filtered glue drips onto the coating roller again, and the heater will heat the inside of the box. After the device has been used for a period of time, the two filter plates are manually removed, the stains on the two filter plates are cleaned, and the two filter plates are reconnected. This reciprocating process can filter the impurities in the glue twice during recycling, and the glue can be broken up during filtration, so that the filtering effect of the glue is better, thereby making the recovery effect of the glue better, and the glue on the inclined plate can be pushed down, so that the glue falls faster, thereby making the recovery efficiency of the glue higher. In addition, the heater can heat the inside of the box to avoid the glue from being blocked in the return pipe as much as possible.
