A coating device for processing PGS composite tape

Abstract

This utility model discloses a coating device for processing PGS composite tape, including a housing and a coating roller. A lower roller assembly is installed inside the lower part of the housing, and the coating roller is installed inside the upper part of the housing. A scraper is installed on the left side of the coating roller, a spray head is positioned above the scraper, and a micro pump is installed on the left side of the scraper. Compared with existing coating devices, this coating device for processing PGS composite tape uses a pressure pump to spray adhesive onto the coating roller through the spray head. As the coating roller rotates, the scraper scrapes off excess adhesive, which is then pumped back into the material tank by the micro pump, improving utilization. The coating roller rotates under external power to apply adhesive onto the tape. The coating roller presses down into the inner side of the lower roller assembly, increasing the contact area between the tape and the coating roller, resulting in better coating. The coated tape passes under a dryer, and the moisture content of the tape is controlled by adjusting the power of the dryer, further improving the coating effect.

Description

Technical Field

[0001] This utility model relates to the field of composite tape processing technology, specifically to a coating device for processing PGS composite tape. Background Technology

[0002] Adhesive tapes can be categorized by their function into high-temperature tapes, double-sided tapes, insulating tapes, specialty tapes, pressure-sensitive tapes, die-cut tapes, etc., each suited to different industry needs. A layer of adhesive is coated on the surface of the tape to bond objects. The earliest adhesives came from animals and plants; in the 19th century, rubber was the main component of adhesives, while modern adhesives widely use various polymers. The tape production process utilizes coating equipment, which applies specific adhesives, coatings, or inks to the tape substrate. The substrate typically includes materials such as plastic film, paper, cloth, and leather. After coating, the tape is dried, then wound and packaged, completing the tape coating process.

[0003] The existing patent, CN221157384U, entitled "A Glue Coating Device for Adhesive Tape Processing," relates to the field of glue coating device technology, specifically a glue coating device for adhesive tape processing. It includes an A-type glue bucket, an A-type glue roller, a C-type glue bucket, a C-type glue roller, and a slow-speed motor. The A-type glue roller is located below the A-type glue bucket, which is located inside a housing and fixedly connected to it. The shaft of the A-type glue roller is rotatably connected to the housing. The C-type glue roller is positioned below the C-type glue bucket, which is also located inside the housing and fixedly connected to it. The C-type glue roller is rotatably connected to the housing, and one end of its shaft is fixedly connected to the shaft of the slow-speed motor. The slow-speed motor is mounted on a motor housing, which is also mounted on the housing. A B-type guide roller is positioned between the A-type and C-type glue buckets, and its shaft is rotatably connected to the housing. A housing cover is located on top of the housing. By installing this device before an existing winding device, it performs re-coating and even-smoothing operations on the adhesive tape, thereby reducing the area of ​​insufficient glue.

[0004] The aforementioned device reduces the area of ​​missing adhesive by re-coating and spreading the adhesive tape before the existing winding device. However, excess adhesive flows out each time it is applied, resulting in waste that needs to be collected and reused, which does not adequately meet people's needs. To address this issue, a technological innovation is proposed based on the existing adhesive application device. Utility Model Content
