Description

Technical Field

[0001] This utility model relates to the field of coating machine feed tank technology, and in particular to a coating machine feed tank that facilitates feed liquid circulation. Background Art

[0002] Coating machines are widely used for coating and composite packaging of substrates such as paper and film. They apply a layer of coating with a specific function to a rolled substrate and then rewind it after the coating dries. The coating machine's trough is a trough in which the coating circulates, containing a coating annulus roller. When coating substrates such as paper and film, the annulus roller rotates inside the trough, applying liquid glue, paint, ink, and other slurries to the substrate.

[0003] Currently, the most common coating machine trough is a rectangular structure with paint inlets and outlets at either end. That is, the trough has a feed port at one end and a discharge port at the other, with paint entering from one end and exiting from the other. This arrangement results in a one-sided feed and one-sided return of the paint. However, due to the inherent properties of the paint, as well as the time-dependent temperature drop and volatility of the paint entering the trough, the viscosity of the paint at the feed and discharge ports can be inconsistent, resulting in a thicker coating on one end of the coating roller and a thinner coating on the other end, which in turn affects the coating quality. Furthermore, the contact surface between the paint and the coating roller is fixed, and because the rectangular trough has many corners, paint accumulates in these corners, resulting in low paint utilization and poor liquid circulation. Furthermore, these corners are difficult to clean when changing coating types, making them time-consuming and labor-intensive. Utility Model Content

[0005] The utility model discloses a coating machine trough which is beneficial to the circulation of material liquid, comprising a trough body, wherein the bottom of the trough body is provided with an arc-shaped bottom trough which matches the axial direction of the coating mesh roller, at least one feed port is axially extended from the middle position of the bottom of the arc-shaped bottom trough, the trough body is provided with discharge ports of the same structure at both ends of the arc-shaped bottom trough, a scraping component which matches the shape of the upper surface of the arc-shaped bottom trough is provided on the upper part of the arc-shaped bottom trough, the scraping component is in contact with the arc-shaped bottom trough and moves back and forth in the axial direction of the arc-shaped bottom trough, so as to facilitate the circulation of coating in the arc-shaped bottom trough.

[0006] As a further technical solution, the scraping component includes a scraping plate that matches the shape of the upper surface of the arc-shaped bottom groove, and vertical portions extend from both ends of the scraping plate.

[0007] As a further technical solution, fixed plates are respectively provided around the upper end of the trough body, and the two fixed plates on one side of the arc-shaped bottom trough are rotatably connected to a screw, and the screw is driven by a driving motor fixedly connected to one side of the fixed plates, and the two fixed plates away from the side of the screw are fixedly connected to a guide rod, and the two vertical parts respectively extend with a connecting end connected to the screw and a sliding end slidably connected to the guide rod.

[0008] As a further technical solution, the scraper plate is made of wear-resistant rubber material.

[0009] As a further technical solution, the scraper plate is a plate-like structure with mesh holes to prevent bubbles from being generated during the scraping process.

[0010] As a further technical solution, six feed ports are evenly arranged along the axis of the arc-shaped bottom trough.

[0011] The beneficial effects of the present invention are as follows: the present invention adopts an arc-shaped bottom trough design in the bottom trough of the trough body, which reduces the space occupied by the paint and the corners of the trough, making cleaning easier. Furthermore, multiple uniform feed ports are provided in the middle of the bottom of the arc-shaped bottom trough, and discharge ports are provided at both ends of the arc-shaped bottom trough. With this structure, the circulating flow generated by the rising paint and the rotation of the coating mesh roller keeps the paint in a uniform state, greatly improving the uniformity of the paint on the coating mesh roller and enhancing the coating quality of the product. A scraping component is provided at the top of the arc-shaped bottom trough, which can move back and forth axially in the arc-shaped bottom trough, further improving the uniformity and circulation of the paint in the arc-shaped bottom trough, and making the circulation of the liquid more uniform.

The coating mesh roller can extend into the arc-shaped bottom trough 2 to adhere to the coating. A plurality of feed ports 3 are axially extended at the middle position of the bottom of the arc-shaped bottom trough 2. The coating enters the arc-shaped bottom trough 2 from the feed port 3 and flows to the two ends of the arc-shaped bottom trough 2. At the same time, the coating is adhered by the coating mesh roller. Only one feed port 3 can be provided, which is located in the middle of the arc-shaped bottom trough 2. Of course, there can also be multiple feed ports 3. In a preferred embodiment, six feed ports 3 are evenly arranged along the axial direction of the arc-shaped bottom trough 2.

[0019] With this structure, the material is fed into the middle of the arc bottom trough 2 and flows to both ends, and the material is discharged from both ends of the arc bottom trough 2, which can make the material liquid circulate more evenly, and the coating is more evenly distributed in the axial direction of the coating mesh roller, thereby improving the coating quality of the product.

[0020] In a preferred embodiment, a scraping component 5 matching the shape of the upper surface of the arc-shaped bottom groove 2 is provided on the upper portion of the arc-shaped bottom groove 2. The scraping component 5 contacts the arc-shaped bottom groove 2 and moves back and forth axially in the arc-shaped bottom groove 2. During the movement of the scraping component 5 back and forth, the paint in the arc-shaped bottom groove 2 is circulated and stirred in the arc-shaped bottom groove 2, so that the paint can circulate in the arc-shaped bottom groove 2, thereby improving the uniformity of the paint in the arc-shaped bottom groove 2 and reducing the axial temperature difference of the paint in the arc-shaped bottom groove 2.

[0022] Of course, in a preferred embodiment, the scraping component 5 is connected to a power component. Specifically, fixed plates 101 are respectively provided around the upper end of the groove 1. Two fixed plates 101 on one axial side of the arc-shaped bottom groove 2 are rotatably connected to lead screws 7. The lead screws 7 are driven by a drive motor 6 fixedly connected to one side of one of the fixed plates 101. Guide rods 8 are fixedly connected to the two fixed plates 101 on the side away from the lead screw 7. The upper ends of the two vertical parts 502 respectively extend a connecting end 503 connected to the lead screw 7 and a sliding end 504 slidably connected to the guide rods 8. Under the action of the drive motor 6, the scraping component 5 moves back and forth along the axis of the arc-shaped bottom groove 2.

[0023] In a preferred embodiment, the scraper 501 can be made of a wear-resistant rubber material. Similarly, the scraper 501 can also be a plate-like structure with mesh to prevent air bubbles from being generated during the scraping process.
