Scraper blade mechanism capable of feeding glue quantitatively

Abstract

The invention discloses a scraper blade mechanism capable of feeding glue quantitatively. The scraper blade mechanism comprises a movable seat and a cutter installation seat, wherein the movable seatis arranged on a machine frame, the cutter installation seat is arranged on the movable seat, a glue discharging box and an upper scraper blade are arranged on the movable seat, the tail of the upperscraper blade is connected with the head of the glue discharging box, a plurality of glue spraying pipes which are evenly distributed are arranged on the glue discharging box, the glue discharging boxis connected with a glue feeding tank, the glue feeding tank is a sealed box body, a thermal insulation layer and a heating mechanism are arranged in the glue feeding tank, a glue discharging pipe isarranged on the glue discharging box, a flow meter is arranged on the glue discharging pipe, and the glue discharging box can be set to quantitatively discharge glue at regular intervals; the head ofthe upper scraper blade extends out of the movable seat, a lower scraper blade is connected to a lower end face of the part extending out of the movable seat of the upper scraper blade through a connection block, and an angle between the lower scraper blade and the connection block can be adjusted. According to the scraper blade mechanism disclosed by the invention, the upper scraper blade and the lower scraper blade are utilized, the upper scraper blade is utilized to feed glue, the lower scraper blade is used for scraping the glue evenly, and the sealed thermal-insulation glue tank is utilized to feed glue; furthermore, the glue can be feed evenly and quantitatively, and the glue feeding quality is ensured.

Description

technical field [0001] The invention relates to the field of composite machines, in particular to a scraper mechanism with quantitative gluing. Background technique [0002] Composite machines are used in clothing fabrics, automotive interiors, leather and other fields. When the composite machine is composited, it is necessary to first glue the material through the rubber roller, and then use a scraper to scrape the glue on the rubber roller evenly. There are several problems in the gluing of the existing compound machine; 1. For some glues that are relatively easy to solidify, heating is required to keep the glue in the glue tank in a molten state. Since the glue tank is designed to be open, it needs to be heated for a long time It is easy to cause the volatilization of glue, and at the same time, the glue tank is open, and a large amount of glue needs to be kept in the glue tank to meet the needs of production, which will consume a lot of energy for long-term heating; 2. W...

[0002] Composite machines are used in clothing fabrics, automotive interiors, leather and other fields. When the composite machine is composited, it is necessary to first glue the material through the rubber roller, and then use a scraper to scrape the glue on the rubber roller evenly. There are several problems in the gluing of the existing compound machine; 1. For some glues that are relatively easy to solidify, heating is required to keep the glue in the glue tank in a molten state. Since the glue tank is designed to be open, it needs to be heated for a long time It is easy to cause the volatilization of glue, and at the same time, the glue tank is open, and a large amount of glue needs to be kept in the glue tank to meet the needs of production, which will consume a lot of energy for long-term heating; 2. When gluing, the glue in the tank The glue will gradually decrease, and it needs to be replenished at any time, and with the decrease of the amount of glue, the glue on the surface of the upper rubber roller will also be uneven. When scraping, there will be a large amount of glue transferred from the upper rubber roller to the scraper blade, which will cause glue accumulation on the scraper blade for a long time, and the excess glue will slide from the scraper blade to the upper rubber roller, resulting in uneven scraping by the scraper blade; if the glue Too little will lead to insufficient glue on the surface of the upper rubber roller, and there will be insufficient glue in some areas after scraping with a scraper, which will affect the quality of the product
