Description

Technical Field

[0001] The utility model relates to the technical field of packaging box coding equipment, in particular to a packaging box coding machine. Background Art

[0002] With the continuous development of the commodity economy, the use of commodity packaging boxes is also increasing. In order to facilitate production management and later mobilization, commodity packaging boxes need to be coded using coding machines during the production process to identify the products.

[0003] The Chinese patent with the prior art authorization announcement number CN212530346U discloses an improved packaging coding machine, which is equipped with a conveyor belt, a fixed seat, a fixed plate, an adjusting screw, a buffer sleeve, a reset spring, a clamping piece and a packaging box body, so that the packaging box body is placed on the fixed seat, and the adjusting screw is rotated so that the buffer sleeve drives the clamping piece to approach each other, and the two sides of the packaging box body are clamped and fixed to avoid displacement during the conveying and coding process. At the same time, when the clamping piece contacts the packaging box body, the reset spring is squeezed, and a part of the squeezing force is absorbed by the deformation and recovery of the reset spring, so as to avoid rigid squeezing of the packaging box body; an air inlet, a dust collector, an air duct and a dust collecting chamber are installed, and air inlets are arranged on both sides of the interior of the arch frame, and the dust collector is connected to the air inlet, and the dust collector is convenient for adsorbing dust impurities in the air around the packaging box body, and the dust device is introduced into the dust collecting chamber inside the base through the air duct to avoid dust adhering to the packaging box body and affecting the clarity of the coding.

[0004] Although the above patent can clamp and fix the packaging box body to prevent the packaging box body from shifting during transportation and coding, and can absorb dust and impurities in the air around the packaging box body to prevent dust from adhering to the packaging box body and affecting the clarity of coding, each packaging box needs to be placed on a fixed seat and then clamped by a clamp. After coding is completed, the clamp needs to be loosened to remove the packaging box, which reduces work efficiency and increases the labor intensity of the staff. Moreover, the vacuum cleaner can only absorb dust and impurities in the air around the packaging box body, but cannot clean the dust on the top of the packaging box, causing the coding machine to spray the barcode on the dust on the top of the packaging box during inkjet coding, resulting in failure of coding of the packaging box, which is not conducive to coding of the packaging box.
