[0048] Please refer to Figures 1 to 7 The embodiment of the present invention provides a carton forming device, which can help improve the degree of automation and assembly efficiency of carton assembly.
[0049] The carton forming equipment comprises a feeding roller 101 , an intermediate roller 102 and a gluing roller 103 which are arranged in sequence; the cartons are transported forward in sequence along the feeding roller 101 , the intermediate roller 102 and the gluing roller 103 .
[0050] A floating paper pressing device 2 is provided on one side of the top of the intermediate roller 102 to flatten the carton on the intermediate roller 102; a first glue spraying device 3 is provided on one side of the floating paper pressing device 2 to apply glue to the first side edge 100 of the carton; a side pressing component 4 and a vertical roller group 5 for positioning the carton are also installed on the intermediate roller 102, and the vertical roller group 5 includes a plurality of vertical rollers arranged at intervals along the conveying direction of the intermediate roller 102; the floating paper pressing device 2 is installed between the vertical roller group 5 and the side pressing component 4, and the side pressing component 4 can push the carton toward the vertical roller group 5 so that the two side paperboards of the carton are glued and fixed by the first side edge 100, and the arrangement direction of the vertical rollers is parallel to the conveying direction of the intermediate roller 102.
[0051] It should be noted that the end cardboards of the carton are prone to upward warping, which may cause the end cardboards to be stuck between the four side cardboards when the side pressure assembly 4 pushes the carton to the vertical roller assembly 5, affecting the deformation of the carton and thus affecting the actual gluing and fixing effect. The end cardboards are actually located at the front and / or rear end during the carton conveying process. The trajectory of the glue sprayed by the first glue spraying device 3 on the first side edge 100 is parallel to the conveying direction of the middle roller 102. When the carton is clamped by the vertical roller assembly 5 and the side pressure assembly 4, the two side cardboards of the carton are butt-glued and fixed, and the carton is in a square shape perpendicular to the conveying direction of the middle roller 102.
[0052] A paper folding device 6 is installed on one side of the top of the gluing roller 103, and a second glue spraying device 7 is provided on one side of the paper folding device 6 to glue the first side edge 100 of the carton, and the first side edge 100 is perpendicular to the second side edge 200; the paper folding device 6 is used to press down the end cardboard of the carton so that the end cardboard is glued and fixed to the second side edge 200.
[0053] In this embodiment, the end cardboard is generally connected to the side cardboard at the top, and the second glue spraying device 7 sprays glue on the second side edge portion 200 of the bottom side panel. The end cardboard is pressed on the glue on the second side edge portion 200, so that the end cardboard and the second side edge portion 200 are glued together, achieving the effect of closing one end of the carton.
[0054] In this embodiment, there is no need to set up a transfer robot or transfer a cart to transport the cartons, and the cartons can be assembled and formed, which effectively improves the assembly efficiency of the cartons.
[0055] Optionally, an inclined paper pressing rod 11 is installed on one side of the top of the loading roller 101, and the paper pressing rod 11 gradually approaches the loading roller 101 along the conveying direction of the loading roller 101; a vertical support column and an adjusting cylinder 12 for adjusting the inclination angle of the paper pressing rod 11 are also installed on the loading roller 101; the paper pressing rod 11 is hinged to the vertical support column, and the paper pressing rod 11 is hinged to the telescopic shaft of the adjusting cylinder 12.
[0056] It should be noted that the paper pressing rod 11 is provided to flatten the upturned end of the paperboard, thereby preventing the floating paper pressing device 2 from pressing the end paperboard onto the side paperboard. In addition, the adjustment cylinder 12 can adjust the inclination angle of the paper pressing rod 11, thereby changing the distance between the paper pressing rod 11 and the conveying surface of the loading roller 101, thereby meeting the assembly requirements of cartons of different thickness specifications.
[0057] Optionally, the floating paper pressing device 2 includes a paper pressing assembly 201, a floating cylinder 202, and a support plate 203. The paper pressing assembly 201 includes a support frame 21, a driving pulley 22, a driven pulley 23, a drive motor 24 for driving the driving pulley 22 to rotate, and a press belt tensioned on the driving pulley 22 and the driven pulley 23. The driving pulley 22 and the driven pulley 23 are both rotatably mounted on the support frame 21, and the drive motor 24 is fixedly connected to the support frame 21. The floating cylinder 202 is mounted on the support plate 203, and the telescopic shaft of the floating cylinder 202 is connected to the support frame 21 to offset part of the weight of the paper pressing assembly 201. The floating cylinder 202 offsets part of the weight of the paper pressing assembly 201, allowing the paper pressing assembly 201 to automatically adjust its position and maintain the downward pressure on the carton after switching between cartons of different thicknesses. In addition, paper jams can be avoided when there are hard objects such as stones inside the carton.
[0058] 4. The carton forming equipment according to claim 1, characterized in that the glue coating roller 103 comprises a plurality of conveying rollers 1031 arranged at intervals, and the surfaces of the conveying rollers 1031 are provided with a Teflon non-stick coating 10311.

[0060] Optionally, the paper folding device 6 further includes a downward pressure beam 63 and a plurality of elastic paper pressing portions 61, each of which is spaced apart and mounted on one side of the bottom of the downward pressure beam 63. As the downward pressure beam 63 moves downward, each of the elastic paper pressing portions 61 simultaneously presses down on the end sheets of the carton. This prevents the top end sheets from being damaged by excessive impact.
[0061] Optionally, the carton forming apparatus further includes a frame; the paper folding device 6 further includes a pre-pressing cylinder 64 mounted on one side of the top of the gluing roller 103. A pre-pressing plate is mounted on the telescopic shaft of the pre-pressing cylinder 64, and the telescopic shaft of the pre-pressing cylinder 64 is vertically arranged. The pre-pressing cylinder 64 can quickly lift or press the pre-pressing plate to pre-press the end sheets of the carton, and then the elastic paper pressing portion 61 presses the end sheets of the carton to a set position.
[0062] Optionally, the second glue spraying device 7 includes a slide rail 71 parallel to the conveying roller 1031 , a glue spraying head 72 slidably mounted on the slide rail 71 , and a sliding drive device 73 for driving the glue spraying head 72 to move along the slide rail 71 .
[0063] Optionally, a discharge roller 104 is further provided at the tail end of the glue coating roller 103 to output the assembled cartons.
[0064] Optionally, a side pusher 8 is further provided on the loading roller conveyor 101; the side pusher 8 includes a side pusher plate and a side pusher drive device for driving the side pusher plate to translate in a direction perpendicular to the conveying direction of the loading roller conveyor 101. The side pusher 8 pushes the unglued cartons, causing them to contact the side pusher device, ensuring that the unglued cartons are properly positioned.
[0065] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concepts of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
