Description

Technical Field

[0001] The utility model relates to the technical field of carton processing, in particular to a carton indentation device. Background Art

[0002] A carton is a rigid paper container made of corrugated cardboard through die-cutting, indentation, box nailing or gluing, and its consumption has always been the first among various packaging products.

[0003] When a carton is being produced and processed, an indentation device presses out armrest marks on both sides of the cardboard. After the armrest marks are cut off, it is convenient for operators to carry the carton. Currently, when the carton is pressing out the armrest marks, a limiting plate is used to limit the cardboard. However, the mouth-shaped structure of the limiting plate can only limit one side of the cardboard. This leads to the situation that after the armrest marks are processed on one side of the cardboard, the operator needs to manually flip it and then use the limiting plate to limit the other side of the cardboard again. Also, due to the limited specifications of the limiting plate, there may be a phenomenon of edge warping at the creasing line during the indentation processing of the cardboard, resulting in different heights of the armrest marks on both sides, which not only affects the aesthetics of the processed carton but also affects the processing efficiency and level of the carton. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that it is relatively inconvenient to press out the armrest marks on the carton in the prior art, and to propose a carton indentation device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A carton indentation device includes an indentation equipment main body, and the indentation equipment main body includes a processing table, a support table, and an indentation plate. The processing table is connected with two limiting blocks through a connecting piece, and a guide rod is fixedly installed on the limiting block. Symmetrically arranged sliders are slidably sleeved on the guide rod, and a pressing plate for pressing the creasing line of the cardboard is integrally connected between two corresponding sliders. The indentation plate is arranged on the pressing plate.

[0007] Preferably, the connecting piece includes a bracket fixedly installed on the processing table, and a cylinder is fixedly installed on the bracket. The output end of the cylinder is fixedly connected with a moving plate, and the two limiting blocks are arranged on the moving plate.

[0008] Preferably, the bracket is in a U-shaped structure, and the moving plate is horizontally arranged above the support table.

[0009] Preferably, the pressing plate is horizontally arranged on both sides of the limiting block, and the two corresponding guide rods are horizontally arranged.

[0010] Preferably, a motor is fixedly installed on the limiting block, and the output end of the motor is fixedly connected with a bidirectional lead screw extending to the other limiting block. Two nuts are slidably sleeved on the bidirectional lead screw, and connecting rods are connected between the pressing plate and the two nuts.

[0011] Preferably, the bidirectional lead screw is horizontally arranged, and the two ends of the connecting rod are respectively pin-connected to the middle end of the pressing plate and the nut.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] 1. By respectively arranging the two indentation plates on the two pressing plates, the utility model can quickly press the armrests on both sides of the cardboard to leave marks, so that the cardboard does not need to be manually flipped during processing, thereby improving the processing efficiency of the cardboard.

[0014] 2. The utility model drives the two limiting blocks to limit the middle end of the cardboard through the moving plate, and then drives the two pressing plates to expand and press the cardboard during reverse movement through the motor, so that the cardboard will not have a warping phenomenon during indentation processing, thereby ensuring the beauty of the cardboard after indentation.

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0020] Refer to Figures 1 - 3A carton creasing device includes a creasing device body, the creasing device body includes a processing table 1, a supporting table 2, and a creasing plate 3. The processing table 1 is connected to two limit blocks 6 through a connecting piece, and a guide rod 7 is fixedly installed on the limit block 6. The creasing plate 3 can automatically rise and fall after being powered on and complete the creasing process on the cardboard. This technical solution is a prior art and will not be elaborated on here.

[0021] The connecting piece includes a bracket fixedly mounted on the processing table 1, and a cylinder 4 is fixedly mounted on the bracket, and a movable plate 5 is fixedly connected to the output end of the cylinder 4. After the cylinder 4 is powered on, the movable plate 5 is driven to rise and fall. This technical solution is a prior art and will not be elaborated on here. Two limit blocks 6 are arranged on the movable plate 5. The bracket is a 匚-shaped structure, and the movable plate 5 is horizontally arranged above the support table 2. After the output end of the cylinder 4 is extended and retracted, the movable plate 5 is driven to move downward, so that the movable plate 5 drives the two limit blocks 6 to extend onto the paperboard, thereby limiting the middle end of the paperboard;

[0022] A symmetrically arranged slider 8 is slidably sleeved on the guide rod 7, and a pressure plate 9 for applying pressure to the cardboard pressing line is integrally connected between two corresponding sliders 8, the indentation plate 3 is arranged on the pressure plate 9, the pressure plate 9 is horizontally arranged at both sides of the limit block 6, and the two guide rods 7 are horizontally arranged correspondingly, the guide rod 7 guides the slider 8, so that the slider 8 can smoothly pull the pressure plate 9 when moving;

[0023] A motor 10 is fixedly mounted on the limit block 6. When the motor 10 is powered on, it drives the bidirectional screw 11 to rotate on the limit block 6. This technical solution is a prior art and will not be elaborated on here. The output end of the motor 10 is fixedly connected to a bidirectional screw 11 extending to another limit block 6. Two matching nuts 12 are provided on the sliding sleeve of the bidirectional screw 11. A connecting rod 13 is connected between the pressure plate 9 and the two nuts 12. The bidirectional screw 11 is horizontally arranged, and the two ends of the connecting rod 13 are respectively connected to the middle end of the pressure plate 9 and the pin shaft of the nut 12. The guide rod 7 guides the moving direction of the slider 8, thereby limiting the moving direction of the nut 12.

[0024] The output end of the motor 10 drives the bidirectional screw 11 to rotate. When the bidirectional screw 11 rotates, it drives the two nuts 12 to move toward each other and can pull the connecting rod 13 to deflect. When the connecting rod 13 deflects, it can resist the pressure plate 9.

[0025] When the two pressure plates 9 move in opposite directions, the cardboard can be unfolded. When the pressure plates 9 move to the positions on both sides of the movable plate 5, they can apply pressure to the cardboard pressing lines, so that the cardboard will not warp after limiting, thereby ensuring that the indentations of the two handrails can be at the same height, thereby improving the efficiency of the carton indentation processing.

[0026] The functional principle of the utility model can be explained through the following operation modes:

[0027] Place the pressed cardboard on the support table 2;

[0028] The output end of the cylinder 4 is extended and retracted to drive the moving plate 5 to move downward, and the moving plate 5 drives the limit block 6 to move downward when moving downward, so that the limit block 6 can limit the cardboard after moving downward;

[0029] When the middle end of the paperboard is limited, the cylinder 4 stops driving;

[0030] The output end of the motor 10 drives the bidirectional screw 11 to rotate, and the bidirectional screw 11 drives the two nuts 12 to move toward or in opposite directions when rotating;

[0031] When the two nuts 12 move toward each other, the traction link 13 deflects, and the position difference generated by the deflection of the link 13 can resist the pressure plate 9. When the pressure plate 9 is subjected to force, the slider 8 slides on the guide rod 7, so that the two pressure plates 9 can extend to the cardboard pressure line when they are in the opposite direction;

[0032] When the pressure plate 9 limits the position of the cardboard pressing line, the indentation plate 3 can indent both sides of the cardboard, so that handrail marks are pressed out on both sides of the cardboard;

[0033] When the cardboard is processed, the cardboard is taken out.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
