Description

[Technical field]

[0001] The utility model relates to the production technology of a product inspection machine, in particular to a static electricity removal device used for the product inspection machine. [Background technology]

[0002] The quality inspection machine inspects the quality of printed products through manual visual inspection or automatic image detection by OCR camera. It collects the printed products when they are detected to be intact, and discards them when defects are detected.

[0003] During operation, when the packaging boxes to be inspected are loaded, the friction between the conveyor belt and the packaging boxes to be inspected is used to transport the packaging boxes to the inspection device. In this way, static electricity is inevitably generated during the transportation process due to the continuous and long-term friction between the conveyor belt and multiple packaging boxes to be inspected. Excessive static electricity may even generate sparks and cause fires. Therefore, it is urgent to effectively eliminate the static electricity generated on the conveyor line of the inspection machine to ensure production safety. [Utility Model Content]

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A static electricity removal device for a product inspection machine, comprising a frame and at least one set of conveyor belts;

[0007] The frame is provided with one or two sets of conveyor belts arranged in parallel and at intervals along its length direction;

[0008] A feeding device for conveying the packaging boxes to be inspected onto the conveyor belt is provided on one side of the conveyor belt;

[0009] The other side of the conveyor belt is provided with a receiving end for collecting and arranging the packaging boxes after inspection on the conveyor belt;

[0010] The starting point of the receiving end is vertically arranged with respect to the conveying direction, and a suspended static elimination component is installed to facilitate the passing of the package box after detection and the end thereof contacts with the bottom plate of the receiving end for conducting and discharging.

[0011] Preferably, the static electricity elimination component includes a crossbeam frame, at least two hanging plates, two aluminum strips that fit together, a carbon fiber static electricity brush and a static electricity lead-out cable. The carbon fiber static electricity brushes are arranged in bundles, and the top ends are fixed by two aluminum strips that fit together. The crossbeam frame is in a "Π" shape and is placed horizontally on the front and rear sides of the receiving end of the frame. The carbon fiber static electricity brush and the aluminum strips are suspended on the crossbeam frame through a plurality of hanging plates, and the lower end of the carbon fiber static electricity brush is elastically in contact with the bottom plate of the receiving end. One end of the aluminum strip is locked and connected to the static electricity lead-out cable by a screw, and the static electricity of the bottom plate touched by the carbon fiber static electricity brush is released.

[0012] Preferably, the frame is provided with a plurality of feed bars arranged in parallel along its length direction in the feeding direction for supporting the conveying of the packaging boxes to be inspected, and the two groups of the conveyor belts are spaced a certain distance apart and the upper end surfaces are arranged flush with the feed bars.

[0013] The beneficial effects of the utility model are:

[0014] An anti-static elimination component is set at the receiving end. Through the suspended carbon fiber anti-static brush, under the premise of facilitating the passage of the packaging box, the end of the carbon fiber anti-static brush touches the bottom plate of the receiving end between the two packaging boxes. The carbon fiber itself can perform corona discharge and contact discharge, which can eliminate part of the static electricity. Or the friction static electricity generated on the bottom plate can be discharged and released through the anti-static lead-out cable, effectively eliminating the static electricity generated on the conveyor line, effectively stabilizing the loading of the packaging box, improving production efficiency, and ensuring safe production.
