Description

Coating device

Technical Field

The utility model relates to a coating technology field, in particular to coating device.

Background

The coating mechanism of the coating machine is suitable for coating glue, ink or other materials with certain effects on coiled substrates so as to be beneficial to printing or improve the paper quality. The coating mechanism of the coating machine mostly adopts a back roll reverse rotation mode to work, so that the coating efficiency can be effectively improved, and a large amount of manpower and material resources are saved. The existing coating machine adopts manual glue adding, a coating roll is placed in a hopper filled with glue, one part of the coating roll is soaked in the glue, the coating roll rotates to wrap the glue on the roll, and the coating is realized by contacting with a film material and cloth, but the vertical distance between the coating roll and the hopper is too large, after the glue in the hopper is partially used, the liquid level of the glue is positioned below the coating roll, so that the coating production is interrupted, and part of the unused glue in the hopper exists. Moreover, the existing hoppers are all open, i.e. hoppers without a top cover, which can cause direct and long-term exposure of the glue to the air, affecting the quality of the glue. And because glue has the adhesion, glue can adhere on the hopper inner wall, is difficult to clean, can lead to like this after adding new glue, and the quality of new glue can be influenced to old glue in the hopper.

Disclosure of Invention

The utility model aims at making improvement and innovation to the shortcoming that exists in the background art with not enough, providing a coating unit, this coating equipment can replace artifical automatic glue that adds, can avoid the hopper internal glue direct and expose for a long time in the air, avoids glue to stew for a long time in the hopper, and is clean easily moreover.

In order to achieve the above purpose, the technical scheme of the utility model is that: the utility model provides a coating device, includes two risers of vertical setting, through the hopper of bolt fastening between the riser, the coating motor that connects at the inside spreader roll of hopper and be connected with the spreader roll through the bearing, the hopper is the U word form, and this hopper bottom circular arc sets up with the spreader roll is concentric, and the interval of hopper bottom circular arc and spreader roll is 5mm, the hopper top sets up the coating mouth, the top of spreader roll exceeds coating mouth 20~30mm, be fixed with the scraper subassembly on the hopper of coating mouth one side, the hopper bottom still is connected with the shunt. By arranging the hopper with the arc-shaped bottom and reducing the distance between the coating roller and the bottom of the hopper to 5mm, the coating roller can completely utilize the glue in the hopper, so that the problem that the coating roller cannot contact with the glue when the liquid level of the glue is too low and the glue is kept stand in the hopper for a long time is avoided. One side of a coating port at the top of the hopper is a top plate integrally formed with the hopper, one side of the coating port is a scraper component, the distance between the top plate and the coating roll is 5-10 mm, the top plate, the scraper component and the coating roll are used for realizing the capping of the hopper, only a gap for the rotation of the coating roll is reserved, and the glue quality is prevented from being influenced by the fact that the glue is directly exposed in the air. Through glue-pouring machine and shunt, utilize controller control, can realize adding glue voluntarily, reduce the human cost, reduce intensity of labour.

In one embodiment, the scraper assembly comprises a sheath fixed on the hopper through bolts and a scraper inserted into the sheath, the sheath is in a flat box shape lacking a narrow end face, one end of the scraper is welded with a screw rod, the screw rod penetrates through the sheath, and a nut is connected to the screw rod outside the sheath in a threaded mode. And the screw and the nut are used for controlling the scraper to advance and retreat, adjusting the distance between the scraper and the coating roller and controlling the coating thickness of the glue.

Because glue is thick, and mobility is poor, utilizes the shunt to divide into the glue of glue filling machine output into the multistrand and pours into the hopper into simultaneously, can guarantee the glue evenly distributed in the hopper, avoids glue to pile up and leads to glue coating inequality.

In one embodiment, the input pipe device is connected with a glue-pouring machine through a hose, and the glue-pouring machine is independently arranged outside the coating machine.

In one embodiment, a teflon coating is sprayed on the inner wall of the hopper. The Teflon coating is sprayed on the inner wall of the hopper, and the hopper is easy to clean due to the fact that Teflon has the characteristic of non-stickiness.

The utility model has the advantages and beneficial effect:

the utility model discloses a set up the hopper of convex bottom to reduce the distance to 5mm of coating roll and hopper bottom, make the glue in the complete utilization hopper of coating roll ability, and then avoid when the glue liquid level crosses low, the coating roll can't contact with glue, and make glue stew in the hopper for a long time. Meanwhile, the top plate, the scraper component and the coating roll which are integrally formed with the hopper realize the sealing cover of the hopper, only a gap for the rotation of the coating roll is reserved, and the glue quality is prevented from being influenced by the fact that the glue is directly exposed in the air. Through glue-pouring machine and shunt, utilize controller control, can realize adding glue voluntarily, reduce the human cost, reduce intensity of labour. The Teflon coating is sprayed on the inner wall of the hopper, and the hopper is easy to clean due to the fact that Teflon has the characteristic of non-stickiness.
