Description

Technical Field

[0001] The present invention relates to the technical field of carton forming equipment, and specifically relates to a box supporting device for carton processing and carton forming. Background Art

[0002] Cartons can be seen everywhere in our daily life and are widely used in commodity packaging. During the production and processing of cartons, processes such as cutting, slotting, pasting, and box supporting are required. Before being loaded into boxes, packaging cartons are often in a folded state, forming flat cartons. To facilitate loading products, workers usually need to manually unfold the folded cartons and then load the products into the cartons.

[0003] Currently, most box forming devices send the cartons into the box chain card slots, then laterally block the edges of the cartons to make the cartons slightly open, and then use the card slots to expand and form the cartons. This method is mainly easier to expand for cartons with thinner paper and deeper creases. However, for cartons with thicker paper or shallower crease line depths, since they are not pre-expanded before being sent into the box chain card slots, it is difficult to fully expand and form the cartons only by lateral blocking, or regular deformation will occur. Moreover, most of the existing box supporting devices for carton forming can only support single-type cartons, and their processing efficiency is also low. Summary of the Invention

[0009] The conveying mechanism is used to assist in opening the paper box and conveying the paper box.

[0010] Furthermore, through holes are provided at the center of the suction cup 2 and the suction cup 1.

[0011] Furthermore, the top end of the spur gear one is meshingly connected with the spur gear two, the side wall of the spur gear two is fixedly connected with a connecting frame, and the connecting frame is sleeved with the rotating shaft one.

[0012] Furthermore, a fixing column is fixedly sleeved on the outer wall of the second rotating shaft, a connecting column is fixedly connected to the bottom of the second cavity column, a circular shell is fixedly connected to the end of the second connecting column, a sealing ring is rotatably sleeved on the outside of the second circular shell, one end of a hose is fixedly connected to the second sealing ring, the other end of the hose is fixedly connected to the input end of a suction pump, and a support frame is fixedly sleeved on the outer wall of the second suction pump.

[0013] Furthermore, one end of a connecting column is fixedly connected to the top of the cavity column, the connecting column is fixedly connected to the fixed column, the other end of the connecting column is fixedly connected to a round shell, a sealing ring is rotatably sleeved in the round shell, one end of a hose is fixedly connected to the sealing ring, the other end of the hose is fixedly connected to an input end of a suction pump, and the suction pump is fixedly connected to a support frame.

[0014] Furthermore, the pre-opening mechanism includes a positioning frame, the ends of which are fixedly connected to two frames, the four inner corners of the two frames are fixedly connected to connecting columns, and a limiting baffle is fixedly connected between the two connecting columns on one side.

[0015] Furthermore, a flip plate is rotatably connected between the two limit baffles, and a torsion spring is fixedly connected at the connection between the flip plate and the limit baffle.

[0016] Furthermore, a protective cover is fixedly connected to the end of the positioning frame, a cylinder is fixedly connected to the inner wall of the protective cover, a lifting seat is fixedly connected to the end of the cylinder, two positioning seats are symmetrically fixedly connected to the top of the lifting seat, one end of a linkage rod is rotatably connected to the two positioning seats, the other ends of the two linkage rods are rotatably connected to a driving seat, two limit columns are slidably sleeved between the two driving seats, and a box support plate is fixedly connected to the top of the two driving seats.

[0017] Furthermore, the conveying mechanism includes two U-shaped frames. A third rotating shaft is rotatably connected between the two U-shaped frames. The outer walls of the two third rotating shafts are fixedly sleeved with winding rollers. The end of one of the third rotating shafts is fixedly connected to the output end of a servo motor. A conveyor belt is sleeved between the exteriors of the two winding rollers.

[0018] Furthermore, a plurality of blocking strips are fixedly connected to the outer surface of the conveyor belt at equal intervals and symmetrically.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. The output end of the driving motor in the box-taking mechanism can drive the first rotating shaft and the circular plate to rotate counterclockwise. Moreover, the circular plate can also drive the second rotating shaft and the first spur gear at its end to rotate meshingly around the second spur gear, so as to drive the first spur gear and the second rotating shaft to rotate clockwise. Then, while the second rotating shaft drives the U-shaped plate to revolve around the first rotating shaft, the U-shaped plate can also rotate around the second rotating shaft. During this process, the U-shaped plate will drive the four first suction cups or second suction cups on both sides to press against the box body. After that, the first suction pump or the second suction pump sucks air from the first hose and the second hose. Since the first hose is communicated with the first cavity column and the second hose is communicated with the second cavity column, the through holes in the first suction cup and the second suction cup will inhale air, so that a negative pressure will be formed between the suction cup pressing on the folding carton and the paper surface. Then, the first suction cup or the second suction cup can draw out the folding carton from the bottom of the limit baffle, and the turnover plate between the limit baffles will quickly reset under the action of the torsion spring to prevent the folding cartons not taken away from continuing to fall.

[0021] 2. The end of the air cylinder drives the lifting seat to contract and descend. The lifting seat drives the two positioning seats at the top to descend. The positioning seats will drive the linkage rod to rotate, so that the ends of the two linkage rods will drive the corresponding driving seats to slide on the limit posts. Therefore, the two driving seats can be driven to move relatively closer. The two supporting box plates and the turnover plate between the two limit baffles remain parallel, and the crease of the folding carton is also parallel to the turnover plate. Therefore, the crease of the folding carton is also parallel to the two supporting box plates. When the two supporting box plates are used to squeeze the folding carton, it will not be deformed irregularly. In this way, the folding carton with a relatively shallow crease or a relatively thick paper can be squeezed into a slightly open or semi-open state. Then, the second rotating shaft drives the U-shaped plate to turn over and sends the slightly opened carton into the conveying mechanism.

[0022] 3. The four suction cups 1 or 2 will adsorb the paper box and the inclined baffle at the end of the conveyor belt, and then the paper box will gradually take shape under pressure. At the same time, after the suction pump 1 or 2 stops working, the folded paper box will stop adsorbing and be released. Then the adjacent baffles will be used to squeeze the paper box in parallel to fully form it. The output end of the servo motor will drive the rotating shaft 3 and the roller to rotate. Then the roller can drive the conveyor belt to transport the opened paper box, so that the product can be boxed and sealed later. This box-supporting device is convenient for supporting various types of paper boxes such as locking type and fastening type, ensuring the success rate of supporting and forming thick cardboard and paper boxes with shallow indentations, reducing irregularly deformed paper boxes. The suction cups 1 and 2 at both ends of the mold plate will move along the same trajectory, so that the two ends of the mold plate can operate synchronously, thereby improving the processing efficiency of paper box forming.

[0036] like Figure 6-7 As shown, in this embodiment, the pre-opening mechanism 200 includes a positioning frame 201, the ends of the positioning frame 201 are fixedly connected to two frames 202, the four inner corners of the two frames 202 are fixedly connected to connecting columns 203, and the two connecting columns 203 on one side are fixedly connected to the limit baffle 204. A flip plate 205 is rotatably connected between the two limit baffles 204, and a torsion spring 206 is fixedly connected to the connection between the flip plate 205 and the limit baffle 204.
