Description

Technical Field

[0001] This utility model relates to a folding device, and more particularly to a synchronous folding device suitable for automatic cartoning machines. Background Technology

[0002] In the packaging process of an automatic cartoning machine, an important step is folding and deforming the paper cards. This involves folding the paper cards along the creases, and the folded paper cards are then used for material conveying. Currently, the common folding method involves using a cylinder lifting mechanism to lift the paper cards during the clamping and conveying process to complete the folding. The drawback is that the mechanism has low precision, and the folding is prone to deviation. Utility Model Content

[0003] The purpose of this invention is to overcome the existing defects and provide a synchronous folding device suitable for automatic cartoning machines, solving the problems of low precision and easy deviation in the current paper card folding mechanism.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A synchronous folding device suitable for an automatic cartoning machine includes a moving suction mechanism and a moving ejection mechanism. The moving suction mechanism includes several horizontally collinear suction blocks, with one suction block in the middle being a reference suction block, and suction blocks on either side of the reference suction block being moving suction blocks. The moving suction mechanism is connected to a drive mechanism for controlling the moving suction blocks to move closer to or further away from the reference suction block. The moving ejection mechanism includes several horizontally collinear top blocks, with a top block provided between the reference suction block and the moving suction blocks, as well as between adjacent moving suction blocks. Each top block can synchronously move closer to or further away from the reference suction block along with the moving suction blocks, and synchronously rises or falls during the process of moving closer to or further away from the reference suction block.

[0006] Furthermore, each of the top blocks is connected to the adjacent reference suction block or movable suction block via a hinge, with one end of the hinge rotatably connected to the top block and the other end of the hinge rotatably connected to the reference suction block or movable suction block.

[0007] Furthermore, the driving mechanism includes a first horizontal fixed plate, with fixed end plates vertically connected to both ends of the upper surface of the first horizontal fixed plate. Two parallel ball splines are arranged between the two fixed end plates. The two ends of the spline shaft of each ball spline are rotatably connected to the fixed end plate. The ends of the two spline shafts on the same side extend to the outside of the fixed end plate and are connected to the motor via a synchronous pulley and synchronous belt. The two ball splines rotate in opposite directions. Two parallel guide rods are arranged above the ball splines between the two fixed end plates, and the reference suction block is sleeved on both guide rods. The system includes a reference suction block, which is fixed at the axial center of the guide rod. The movable suction blocks can slide freely along the guide rod. A cam follower is provided on the lower end face of each movable suction block. Vacuum suction cups are provided on the upper end faces of both the reference suction block and the movable suction blocks. Vacuum ports are provided on the sides of both the reference suction block and the movable suction blocks. A cam is fitted on the spline outer cylinder of each ball spline. A translational cam groove is provided on the outer surface of the cam. Movable suction blocks located on the same side of the reference suction block correspond to one cam and are connected by the cooperation of the cam follower and the translational cam groove.

[0008] Furthermore, a positioning follower is provided on the upper end face of the first horizontal fixed plate below the cam, and a positioning cam groove that cooperates with the positioning follower is provided on the outer surface of the cam.

[0009] Furthermore, a second horizontal fixing plate is connected to the lower end face of the first horizontal fixing plate, and the motor is connected to the end of the second horizontal fixing plate through a vertical connecting plate.

[0010] Furthermore, it includes an auxiliary adsorption mechanism, which is disposed above the mobile adsorption mechanism. The structure of the auxiliary adsorption mechanism is the same as that of the mobile adsorption mechanism, but the adsorption surface faces downward. The suction block of the auxiliary adsorption mechanism is aligned vertically with the suction block of the mobile adsorption mechanism.

[0011] Furthermore, a robotic arm connector is provided on the top of the auxiliary adsorption mechanism.

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0019] like Figure 1-4 As shown, a synchronous folding device suitable for an automatic cartoning machine includes a moving suction mechanism and a moving ejection mechanism. The moving suction mechanism includes five horizontally collinear suction blocks, with the suction block in the middle being a reference suction block 1, and the suction blocks on both sides of the reference suction block 1 being moving suction blocks 2. The moving suction mechanism is connected to a drive mechanism for controlling the moving suction blocks 2 to move closer to or further away from the reference suction block 1. The moving ejection mechanism includes four horizontally collinear ejection blocks 3. An ejection block 3 is provided between the reference suction block 1 and the moving suction blocks 2, as well as between adjacent moving suction blocks 2. Each ejection block 3 can move closer to or further away from the reference suction block 1 synchronously with the moving suction blocks 2, and rises or falls synchronously during the process of moving closer to or further away from the reference suction block 1.

[0020] Each top block 3 is connected to the adjacent reference suction block 1 or movable suction block 2 via a hinge 4. One end of the hinge 4 is rotatably connected to the top block 3, and the other end of the hinge 4 is rotatably connected to the reference suction block 1 or movable suction block 2. The hinge 4 is positioned on both sides of the top block 3 and the suction block in the horizontal movement direction to ensure the compactness of the top block 3 and the suction block during ejection, fully meeting the requirements of paper card folding.

[0021] The drive mechanism includes a first horizontal fixed plate 5, with fixed end plates 6 vertically connected to both ends of the upper surface of the first horizontal fixed plate 5. Two parallel ball splines 7 are arranged between the two fixed end plates 6. The two ends of the spline shaft of each ball spline 7 are rotatably connected to the fixed end plate 6. The ends of the two spline shafts on the same side extend to the outside of the fixed end plate 6 and are connected to a motor (not shown in the figure) via a synchronous pulley and a synchronous belt 8. The two ball splines 7 rotate in opposite directions. Two parallel guide rods 9 are arranged above the ball splines 7 between the two fixed end plates 6. A reference suction block 1 and a movable suction block 2 are mounted on both guide rods 9. The reference suction block 1 is fixed at the axial center of the guide rod 9, and the movable suction block 2 can slide freely along the guide rod 9. A cam follower 10 is provided on the lower end face of each movable suction block 2. A vacuum suction cup 11 is provided on the upper end face of both the reference suction block 1 and the movable suction block 2. A vacuum port 12 is provided on the side of both the reference suction block 1 and the movable suction block 2. A cam 13 is sleeved on the spline outer cylinder of each ball spline 7. A translation cam groove 14 is provided on the outer surface of the cam 13. The movable suction blocks 2 located on the same side of the reference suction block 1 correspond to the same cam 13 and are connected by the cooperation of the cam follower 10 and the translation cam groove 14.

[0022] The lower end face of the first horizontal fixing plate 5 is connected to the second horizontal fixing plate 15, and the end of the second horizontal fixing plate 15 is connected to the motor through the vertical connecting plate 16.

[0023] The device also includes an auxiliary adsorption mechanism, which is located above the moving adsorption mechanism. The structure of the auxiliary adsorption mechanism is the same as that of the moving adsorption mechanism, but the adsorption surface faces downward. The suction blocks of the auxiliary adsorption mechanism and the suction blocks of the moving adsorption mechanism are aligned vertically.

[0024] The top of the auxiliary adsorption mechanism is equipped with a robotic arm connector 17 and connected to a robotic arm (not shown in the figure).

[0025] Working principle:

[0026] First, the suction blocks of the moving adsorption mechanism and the auxiliary adsorption mechanism are at their maximum spacing. The auxiliary adsorption mechanism (vacuum adsorption activated) adsorbs the paper card to be folded. The robot controls the auxiliary adsorption mechanism to move above the moving adsorption mechanism and then descends, so that the suction blocks of the auxiliary adsorption mechanism cooperate with the suction blocks of the moving adsorption mechanism to clamp the paper card to be folded. The suction blocks of the moving adsorption mechanism activate vacuum adsorption. At this time, the part to be folded is located above the top block 3.

[0027] Then, the motors of the moving adsorption mechanism and the auxiliary adsorption mechanism run simultaneously, driving the cam 13 to move horizontally through the ball spline 7. Through the cooperation of the cam groove and the cam follower 10, the moving suction blocks 2 of the moving adsorption mechanism and the auxiliary adsorption mechanism move closer to their respective reference suction blocks 1 until they are completely closed. During this process, the top block 3 rises and lifts the part to be folded upward to complete the paper folding work.

[0028] Finally, the suction block of the moving adsorption mechanism shuts off vacuum adsorption, and the robotic arm controls the auxiliary adsorption mechanism (turns on vacuum adsorption) to send the folded paper to the next process.

[0029] A positioning follower 18 is provided on the upper end face of the first horizontal fixed plate 5 below the cam 13, and a positioning cam groove 19 that cooperates with the positioning follower 18 is provided on the outer surface of the cam 13. The above structure is used to ensure the stability of the cam 13 when it moves horizontally.

[0030] This utility model discloses a synchronous folding device suitable for automatic cartoning machines. It adopts a mechanical structure that links the suction block and the top block, which lifts the paper card to complete the folding while ensuring effective fixation of the paper card, thereby ensuring that the folding does not deviate.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
