Problems solved by technology

[0002] Disposable paper cups are widely used in people's daily life. At present, the quality inspection process of paper cups mostly adopts manual sampling inspection or watertight inspection. Manual sampling inspection will have uncertainties. Only probability statistics can be used to roughly control the quality, and it is impossible to ensure the quality of each paper cup. All are qualified products, and the watertight test will cause destructive damage to the paper cup

Embodiment 1

[0035] The paper cup online leak detection device is composed of a gas injection mechanism, a conveyor belt 4, an infrared thermal imager 5 and a monitor 8. The paper cup 1 to be detected is transported to the bottom of the gas injection mechanism by the conveyor belt 4 in an intermittent flow mode, and the infrared thermal imager 5 is placed on the side of the conveyor belt 4 to collect the infrared image of the paper cup 1. The monitor 8 is connected to the infrared thermal imager 5 to display the image of the infrared image. Such a leak detection device can manually observe whether there are unqualified paper cups 1. Low device cost and reliable operation.

[0036] The air injection mechanism is arranged above the conveyor belt 4, including a pressure plate 3 for covering the opening end of the paper cup 1, an air injection pipe 2 passing through the pressure plate 3 to inject hot air into the paper cup 1, and a telescopic unit connecting the pressure plate 3 and the air inj...

Embodiment 2

[0039] The paper cup online leak detection device is composed of an air injection mechanism, a conveyor belt 4, an infrared thermal imager 5, a controller 6 and a defective product rejection mechanism 7, and the paper cup 1 to be detected is transported to the gas injection mechanism by the conveyor belt 4 in an intermittent flow mode Below, the thermal imaging camera 5 is placed on the side of the conveyor belt 4 to collect the infrared image of the paper cup 1, the controller 6 is connected to the thermal imaging camera 5 to receive the image signal, and the defective product removal mechanism 7 is connected to the controller 6 to receive the control The unqualified products are eliminated after the rejecting signal of the controller 6. This detection method of automatically removing the unqualified products through the controller 6 has high working effect, strong reliability, and reduces work intensity.

[0040] In addition, the controller 6 can also be connected with a moni...

Abstract

The invention discloses an on-line paper cup leakage detecting device. The on-line paper cup leakage detecting device comprises a conveying belt used for conveying a paper cup, a thermal infrared imager fixed beside the conveying belt and used for collecting the infrared imagery of the paper cup, and an air injection mechanism arranged above the conveying belt. The on-line paper cup leakage detecting device is further provided with a controller and / or a monitor connected with the thermal infrared imager and used for judging whether the paper cup is qualified. The air injection mechanism comprises a pressing plate used for covering the opening end face of the paper cup, an air injection pipe penetrating through the pressing plate to inject hot air into the paper cup, and a stretchable unit used for connecting the pressing plate with the air injection pipe. According to the on-line paper cup leakage detecting device, the infrared thermal imaging non-contact non-destructive testing technology is adopted, full-automatic leakage detection and selection of disposable paper cups on a production line are achieved, and nondeterminacy caused by manual sampling detection and destructiveness caused by water-used detection are avoided.

Description

technical field [0001] The invention relates to a detection device, in particular to a device for detecting whether there is a water leakage defect in a disposable paper cup. Background technique [0002] Disposable paper cups are widely used in people's daily life. At present, the quality inspection process of paper cups mostly adopts manual sampling inspection or watertight inspection. Manual sampling inspection will have uncertainties. Only probability statistics can be used to roughly control the quality, and it is impossible to ensure the quality of each paper cup. All are qualified products, and the watertight test will cause destructive damage to the paper cup. Contents of the invention [0003] The technical problem to be solved by the invention is to realize a fast, efficient and reliable paper cup leak detection device. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: an online leak detection device for p...
