Description

Technical Field

[0001] The present invention relates to the technical field of strip box packaging, in particular to a strip box packaging machine. Background Art

[0002] At present, many cigarettes and small firecrackers are packaged in strip boxes. The document with patent application number CN202211472730.2 discloses a multi-layer material strip box packaging machine. When the material is pressed against the limit baffle under the transmission of the conveyor belt, the pressure sensor senses the pressure, the conveyor belt stops conveying, and the negative pressure suction piece sucks a piece of box paper and makes it fall into the paper jam slot. The push plate pushes the material to the connecting skin of the box paper, so that the upper box skin and the lower box skin of the box paper are respectively located on the upper and lower sides of the material. The folding splint clamps the folding paper of the box paper and bends it. The strip box is located on the forming mechanism, and the glue head applies glue at the first folding edge and the second folding edge to complete the strip box packaging.

[0003] The above-mentioned strip box packaging machine has the following problems: 1. The structure and action of the folding splint cannot be known from the manual, so it is unclear how to use the folding splint to bend the folding paper of the box cover; 2. It is necessary to set a paper jam slot for clamping the box cover and a folding splint set at the paper jam slot. The two are combined to bend the box cover. The paper box forming and gluing must be completed before the material can be output. The forming and output of the strip box cannot be carried out simultaneously, and its efficiency is low. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a strip box packaging machine in view of the above-mentioned deficiencies in the prior art.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a strip box packaging machine, comprising a storage channel filled with box paper, a feeding mechanism for transporting materials, a forming mechanism for folding the box paper into a box shape, and a pushing mechanism for pushing materials into the box paper. A transfer component for conveying the box paper is provided between the storage channel and the forming mechanism. The feeding mechanism is located below the storage channel, the pushing mechanism is located on one side of the feeding mechanism, and the forming mechanism is located on the other side of the feeding mechanism. It is characterized in that the forming mechanism includes a folding component located below the transfer component and a conveyor belt for transporting the formed strip boxes. The folding components are arranged on both sides of the conveyor belt and can simultaneously bend the bent paper of the box paper. Glue dispensing components for gluing the bent paper are provided on both sides of the folding component.

[0006] The present invention has the above-mentioned characteristics: the folding components are arranged at both ends of the conveyor belt, so that the folding components bend the folding paper of the box skin paper while the box skin paper moves along the conveyor belt, and the gluing components are arranged on both sides of the folding components to complete the gluing while bending. Through the above-mentioned technical scheme, the strip box forming speed is greatly improved, and the production efficiency is improved.

[0007] A further arrangement of the present invention is that the folding assembly includes an upper pressure plate located above the conveyor belt and first folding blocks respectively installed at both ends of the upper pressure plate to bend the folding paper of the box paper, the upper pressure plate is provided with a strip groove for the box paper to pass through, and both sides of the conveyor belt are provided with folding seats to keep the bent paper in a bent state, the suspended end of the first folding block extends to be in contact with the folding seat, and the folding seat is provided with a second folding block on the side close to the glue dispensing assembly, the lower end of the first folding block and the upper end of the second folding block form a feeding gap for the bent paper of the box paper to pass through, and the suspended end of the first folding block is provided with a lower folding piece to make the bent paper of the box paper downward.

[0009] A further configuration of the present invention is that the folding seat includes a folding knife upright on the side of the conveyor belt, a side pressure plate suspended above the conveyor belt, and at least one group of connecting components that fix the folding knife to the side of the conveyor belt. The end of the folding knife close to the first folding block is provided with an inclined surface inclined toward the conveying direction of the conveyor belt. The side pressure plate is fixedly connected to the folding knife, and the two are vertically connected.

[0010] The present invention has the above-mentioned characteristics: the side pressure plate has a guarding effect on the upper box skin of the strip box, and the folding knife has a guarding effect on the bent paper of the strip box. The side pressure plate and the folding knife are perpendicular to each other in space, helping the strip box to maintain its shape; the end of the folding knife facing the first folding block is set as a downward inclined surface, which is consistent with the forward direction of the material, so that the bent paper of the box skin paper can smoothly enter the folding seat after being bent.

[0011] A further arrangement of the present invention is that the connecting assembly includes a mounting bar that is adjustably connected to the conveyor belt, a mounting block erected on the upper end surface of the mounting bar, and a connecting bar hinged to the mounting block, the mounting block and the connecting bar are hinged by a pin shaft, at least two pin shaft holes for mounting pin shafts are arranged in parallel on the mounting block, a support member for limiting the rotation of the connecting bar is provided on the mounting block, a spring shaft connected to the side pressure plate is installed on the connecting bar, a compression spring is sleeved on the spring shaft, and the mounting block is connected to the folding knife.

[0012] The present invention with the above characteristics: by setting a connecting component, the folding seat is set at both ends of the conveyor belt; at least two parallel pin shaft holes are set on the mounting block to realize the adjustment of the height of the side pressure plate, which is suitable for strip boxes of different sizes; a spring shaft connected to the side pressure plate is set on the connecting strip, so that the side pressure plate has a certain movement space and has a shock-absorbing and buffering effect.

[0013] A further arrangement of the present invention is: the glue dispensing assembly includes a glue box located below the folding assembly, and a glue dispensing seat erected on the side of the glue box away from the feeding mechanism. A glue dispensing shaft is passed through the glue dispensing seat, one end of the glue dispensing shaft is connected to a power part that drives it to rotate, and the other end is equipped with a glue dispensing rod. The glue dispensing rod is suspended above the glue box and can be rotated to apply glue to the box paper.

[0014] The present invention has the above characteristics: the glue box is arranged below the folding assembly and is used in conjunction with the folding assembly; by setting a rotatable glue dispensing rod, and the glue dispensing rod is located below the folding assembly, glue can be applied to the unfolded folded paper.

[0015] A further configuration of the present invention is that the pushing mechanism includes a pushing platform, a pushing plate slidably connected to the pushing platform, and a driving member driving the pushing plate to move toward or away from the feeding mechanism, and a cover plate is provided on the pushing plate.

[0016] The present invention with the above characteristics: a cover plate is provided on the push plate to prevent dust; and the push plate is provided to push the material toward the forming mechanism.
