3results about How to "Prevent sticking back" patented technology

This utility model discloses a belt scale with a cleaning effect, including a conveyor belt, multiple support components, a first scraping component, a second scraping component, and a roller brush assembly. The conveyor belt is positioned between two support plates via rollers. The multiple support components are respectively positioned below the return section of the conveyor belt and are in contact with the conveyor belt. The return section of the conveyor belt is equipped with a speed measuring roller and a weighing mechanism, which are respectively connected to a controller. The first scraping component is inclinedly positioned between the two support plates. The second scraping component reciprocates and is positioned on the scraping surface of the first scraping component, and is connected to a drive mechanism. The roller brush assembly is rotatably positioned below the return section of the conveyor belt and is connected to the drive mechanism via a transmission component. Thus, the reciprocating motion of the second scraper can promptly remove material adhering to the first scraper, preventing it from sticking back to the conveyor belt. This improves the surface cleaning effect of the conveyor belt and enhances the weighing accuracy of the belt scale.

A tape dispenser includes a main body, a cutter, and an adhesive backing portion having a pressure sensitive adhesive on a surface thereof. The adhesive backing portion is fixedly attached to the cutter and protrudes from the main body. The adhesive backing portion contacts and adheres to the back of the tape head after the tape is cut by the cutter to prevent the tape head from flying or sticking back. The adhesive backing portion presses the tape head against an object to be taped when the tape dispenser is used again.

The invention relates to a die cutting waste discharge device and a die cutting waste discharge method.The die cutting waste discharge device comprises a first feeding mechanism, a die cutting mechanism, a lifting waste discharge mechanism and a winding mechanism which are sequentially arranged in the advancing direction of a material belt, and the first feeding mechanism is used for inputting the material belt; the die cutting mechanism comprises an ejector pin, a garbage can, a lower die base, an upper die base and cutter points, the cutter points with different die cutting depths are arranged below the upper die base, the ejector pin is arranged on the side, away from the first feeding mechanism, of the upper die base, the garbage can is arranged below the lower die base, and the cutter points are used for die cutting of material belts. The material belt subjected to die cutting is conveyed to an ejector pin to eject waste materials, and the waste materials fall into a garbage can; the lifting waste discharge mechanism is used for collecting and discharging outer frame waste after material belt die cutting; and the winding mechanism is used for winding the treated material belt to obtain a product. Compared with the prior art, waste is discharged after die cutting, auxiliary materials are saved, the waste discharging efficiency is improved, and the waste discharging cost is reduced.
