Description

Technical Field

[0001] This utility model relates to the field of edge folding technology for gluing machines, and in particular to an edge folding device for gluing machines. Background Technology

[0002] The gluing and folding machine is a key sub-segment of the packaging machinery industry that focuses on the post-processing of paper products. It mainly revolves around the forming process of paper packaging such as folding boxes, cartons, and paper bags. Its core function is to complete the precise folding and gluing of paper products through automated equipment, realizing the efficient transformation from flat cardboard to three-dimensional packaging boxes. In the glue application stage of the folding device of the gluing machine, traditional devices mostly use drip-type glue application. Drip-type glue application controls the glue to drip onto the folding position through a solenoid valve. Although it can control the amount of glue, the synchronization between the glue dripping speed and the paper conveying speed is poor, which can easily lead to glue leakage or uneven glue distribution, and the glue dripping accuracy is difficult to guarantee.

Support frames 2 are fixedly connected to the left and right surfaces of the machine tool 1. Four conveyor boxes 7 are provided on the upper surface of the machine tool 1. The conveyor box 7 near the discharge port is fixedly connected to the fixed plate 5, while the conveyor box 7 not connected to the fixed plate 5 is fixedly connected to the support frame 2. Multiple rollers 9 are fixedly connected to the lower surface of each conveyor box 7, and roller sleeves 8 are rotatably fitted onto the outer surface of the multiple rollers 9 of each conveyor box 7. A glue box 10 is fixedly connected to the right surface of the conveyor box 7 located in the middle of the machine tool 1, and fixed blocks 11 are fixedly connected to both the left and right surfaces of the glue box 10. A glue applicator is installed at the lower end of the glue box 10. The glue applicator includes a glue brushing wheel 101, which is rotatably connected to the glue box 10. The glue brushing wheel 101 is annular, and an internal gear ring 102 is fixedly connected to the inner ring of the glue brushing wheel 101. A large gear 105 and a small gear 106 are meshed on the inner wall of the internal gear ring 102. The large gear 105 and the small gear 106 do not contact each other. A large shaft 103 and a small shaft 111 are provided inside the glue brushing wheel 101. Both ends of the large shaft 103 and the small shaft 111 are fixedly connected to two fixed blocks 11 respectively. A large shaft sleeve 104 is rotatably sleeved on the outer surface of the large shaft 103. The large gear 105 and the large shaft sleeve 104 are fixedly connected. The small shaft 111 is rotatably sleeved with a small bushing 112 on its outer surface. The small gear 106 and the small bushing 112 are fixedly sleeved together. The large gear 105 and the small gear 106 are fixed at both ends of the large bushing 104 and the small bushing 112, respectively. The outer surface of the large bushing 104 and the small bushing 112 is rotatably sleeved with a transmission belt 110 in the middle. The brushing wheel 101 has multiple cylindrical holes 109 inside. The multiple cylindrical holes 109 are slidably connected to a connecting block 107 and a piston 108, respectively. The piston 108 is fixedly connected to the connecting block 107. The end of the connecting block 107 that is not connected to the piston 108 is fixedly connected to the transmission belt 110.

[0019] Working principle: The four conveyor boxes 7 are started. The start of the conveyor boxes 7 causes the rollers 9 and roller sleeves 8 to rotate, and the material is fed into the roller sleeves 8 through the pressure plate 4. The rotation of the roller sleeves 8 drives the material to move towards the discharge port 6. When the material moves to the brushing wheel 101, the material drives the brushing wheel 101 to rotate. The rotation of the brushing wheel 101 drives the internal gear ring 102 to rotate. The rotation of the internal gear ring 102 drives the large gear 105 and the small gear 106 to rotate. The rotation of the large gear 105 and the small gear 106 drives the large bushing 104 and the small bushing 112 to rotate. The rotation of the large bushing 104 and the small bushing 112 drives the transmission belt 110 to rotate, so that the transmission belt 110 and the brushing wheel 101 rotate synchronously. When the upper part of the glue-brushing wheel 101 rotates into the glue tank, the transmission belt 110 pulls the connecting block 107 to slide into the glue-brushing wheel 101. The sliding of the connecting block 107 into the glue-brushing wheel 101 drives the piston 108 to slide into the glue-brushing wheel 101. The piston 108 slides into the glue-brushing wheel 101 and sucks the glue in the glue tank 10 into the cylindrical hole 109. As the glue-brushing wheel 101 rotates, the cylindrical hole 109 with glue rotates out of the glue tank 10. When the cylindrical hole 109 with glue approaches the material, the transmission belt 110 pushes the connecting block 107. The connecting block 107 pushes the piston 108. The piston 108 pushes the glue out of the cylindrical hole 109 and applies it to the material. The roller sleeve 8 continues to convey the material to the discharge port 6. When the right end of the material moves to the bending rod 3, the material bends according to the arc of the bending rod 3 and folds the material in half, adhering the position where the glue was just applied. Then the roller sleeve 8 conveys the material to the discharge port 6, and the material is discharged from the discharge port 6, completing the folding of the glued box.

[0020] The rotation of the large bushing 104 and the small bushing 112 drives the transmission belt 110 to rotate. The rotation of the transmission belt 110 then drives the connecting block 107 to slide in the cylindrical hole 109. The sliding of the connecting block 107 in the cylindrical hole 109 allows for the absorption and extrusion of glue inside the glue box 10, evenly applying the glue to the glue application point. This avoids glue overflow caused by excessive glue in certain areas and also prevents weak adhesion caused by insufficient glue, thus ensuring the structural stability of the cardboard box after molding.

[0021] The internal gear ring 102 meshes with the large gear 105 and the small gear 106 to provide power to the large bushing 104 and the small bushing 112. When the glue brushing wheel 101 drives the piston 108 to rotate, the lower transmission belt 110 drives the connecting block 107 to rotate simultaneously with the piston 108, ensuring the stability of power transmission and making the glue application more stable and uniform.

[0040] Piston 108: It is fixedly connected to the connecting block 107 and slidably connected inside the cylindrical hole 109. Driven by the connecting block 107, it slides inside the cylindrical hole 109. When it slides into the glue roller 101, it draws the glue in the glue box 10 into the cylindrical hole 109.
