Description

Technical Field

[0001] The utility model relates to the technical field of packaging box production, in particular to an edge binding device for packaging boxes. Background Art

[0002] As the name implies, packaging boxes are boxes used to package products. They can be classified by material, such as paper boxes, iron boxes, wooden boxes, cloth boxes, leather boxes, acrylic boxes, corrugated packaging boxes, PVC boxes, etc. They can also be classified by product name, such as moon cake boxes, tea boxes, wolfberry boxes, candy boxes, exquisite gift boxes, local specialty boxes, wine boxes, chocolate boxes, food, medicine and health care product boxes, food packaging boxes, tea packaging boxes, pencil cases, etc. Functions of packaging boxes: ensure the safety of products in transportation and improve the grade of products.

[0003] Most existing packaging boxes are made of cardboard, which can improve the support of the packaging box and reduce the phenomenon of squeezing and deformation of the packaging box. In order to further improve the anti-deformation effect of the packaging box or improve the aesthetics of the packaging box, the packaging box needs to be edged. During the edge-banding process, a layer of protective cardboard or cardboard printed with patterns will be glued to the side of the packaging box.

[0004] Traditionally, glue is applied to cardboard manually, and then the packaging box is placed on the cardboard to bond them together with the glue. However, during the bonding process, the cardboard needs to be pressed against the packaging box manually to allow the glue to firmly bond the cardboard and the packaging box, which makes the hemming operation of the packaging box more troublesome. Utility Model Content

[0005] The utility model aims to address the defects and shortcomings of the prior art and to provide a packaging box edge wrapping device which does not require manual hands to continuously press the paperboard and is relatively simple to operate for edge wrapping of the packaging box.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a packaging box edge wrapping device, comprising a workbench, and also comprising two support blocks symmetrically arranged on the workbench for supporting the side end surfaces of the cardboard, two mounting posts symmetrically arranged on the workbench and located on one side of the support blocks, transverse through holes respectively opened on the two mounting posts, a sliding rod slidably arranged on the two mounting posts and located in the transverse through holes for moving to the cardboard end to a predetermined position when driven by an external force, a squeezing plate arranged on the sliding rod at the end of the support block for squeezing the cardboard onto the packaging box when the sliding rod moves to the predetermined position toward the cardboard end, and a fixing member arranged between the support block and the sliding rod for fixing the sliding rod to the support block when the squeezing plate squeezes the cardboard onto the packaging box.

[0007] A further improvement is that an inclined surface is arranged on the end of the support block close to the paperboard.

[0008] A further improvement is that the fixing member includes a longitudinal opening longitudinally opened at the upper end of the mounting column, a corresponding card slot opened on the sliding rod and used to correspond to the position of the longitudinal opening when the extrusion plate squeezes the cardboard onto the packaging box, and a longitudinal sliding rod that can be lifted and lowered on the mounting column and located in the longitudinal opening and used to be engaged and connected with the corresponding card slot when the corresponding card slot corresponds to the position of the longitudinal opening.

[0009] A further improvement is that the upper end surface of the longitudinal slide bar is provided with a counterweight block for allowing the longitudinal slide bar to descend and engage with the corresponding slot when the corresponding slot corresponds to the position of the longitudinal opening.

[0010] A further improvement is that: a driving plate is arranged on the end face of the sliding rod away from the supporting block, a compression spring is arranged between the driving plate and the mounting column, and the compression spring is sleeved on the sliding rod.

[0011] A further improvement is that a flexible plate is provided on the end surface of the extrusion plate close to the paperboard for preventing the paperboard from being damaged when the extrusion plate squeezes the paperboard onto the packaging box.

[0012] A further improvement is that the flexible board is a silica gel board, a latex board or a sponge board.

[0013] After adopting the above technical scheme, the beneficial effect of the utility model is as follows: when it is necessary to hem the packaging box, first place the cardboard on the upper end surface of the workbench in the middle of the two supporting blocks, apply glue on the adhesive surface of the cardboard, and then place the packaging box in the middle position of the cardboard so that the two sides of the cardboard are placed on the supporting blocks, and then push the sliding rod by hand to drive the extrusion plate to move toward the side end surface of the cardboard, so that the extrusion plate squeezes the cardboard on the packaging box. At this time, the corresponding card slot corresponds to the position of the longitudinal opening, and the longitudinal slide bar naturally falls in the longitudinal opening or is pressed down by hand to make the longitudinal slide bar engage with the corresponding card slot, thereby limiting the left and right movement of the slide bar, so that the cardboard can be kept continuously squeezed on the packaging box, and there is no need for manual hands to continuously press the cardboard, and the hem wrapping operation of the packaging box is relatively simple.

[0014] Further effect: when the sliding rod moves toward the cardboard end to the squeezing plate to squeeze the cardboard onto the packaging box, the left and right sliding of the sliding rod is limited by the cooperation between the sliding rod and the corresponding card slot, so that when the glue is applied, there is no need for the worker's hands to continue pressing the cardboard onto the packaging box. When it is necessary to release the pressure of the squeezing plate on the cardboard, the sliding rod is pulled upward to make it lose cooperation with the corresponding card slot, and then the sliding rod is pulled outward to remove the packaging box from the workbench.

[0015] Further effect: when the hand pulls the sliding rod upward to make it lose the match with the corresponding card slot, the elastic potential energy generated by the contraction of the compression spring pushes the driving plate to drive the sliding rod away from the cardboard end, thereby realizing the reset effect of the sliding rod.
