Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to a packaging box lining forming mechanism and a packaging box lining adding system. Background Art

[0002] Currently, the market has a huge demand for one-piece packaging, and there are requirements for the cardboard and liner folding mechanism to be fast, small in space, and precise in positioning.

[0003] The liner forming process of the existing one-piece packaging machine is as follows: a robot takes out the liner from the bottom of the liner bin, another robot grabs it from the top of the liner and transfers it to the forming mechanism to complete the forming of the liner, and the formed liner is then transferred to the box body; the existing forming process is relatively complicated, time-consuming, and occupies a large space. For example, a one-piece carton folding and forming machine with patent number CN116409501A: during the forming process, it is transferred to the two-time forming mechanism by a robot for forming, which is time-consuming and complicated to operate.

[0004] To address the above problems, a forming mechanism can be set on the robot arm. The robot arm picks up a piece of packaging from the silo and transfers it to the box body. The lining is formed during the transfer process, which is highly efficient and takes up little space. However, how to set the forming mechanism to meet the needs of the lining forming is not involved in the existing technology. Utility Model Content

[0005] The purpose of the utility model is to provide a packaging box liner forming mechanism and a packaging box liner adding system, which solves the problem of how to complete liner forming simultaneously during the liner transportation process.

[0006] The utility model is implemented in this way. A packaging box liner forming mechanism comprises a fixed seat and movable seats arranged on both sides of the fixed seat. The fixed seat and the movable seat are provided with fixing mechanisms for fixing the liner. A liftable bending component is provided between the fixed seat and the movable seat.

[0007] The lining is placed on a fixed seat and a movable seat, and then fixed by a fixing mechanism. During molding, the lining is folded along the crease by moving the movable seat. During this molding process, a lifting and lowering bending component is arranged between the fixed seat and the movable seat to ensure that the lining is folded in the correct direction. The lining molding has a high qualified rate, which ensures the smooth progress of subsequent processes.

[0008] A further technical solution of the utility model is: a guiding slope is provided between the fixed seat and the movable seat, the guiding slope cooperates with the bending assembly, and the movable seat can move in a direction close to or away from the fixed seat for the bending assembly to be lifted and lowered along the guiding slope.

[0009] The guide slope is arranged between the fixed seat and the movable seat. During the movement of the movable seat, the bending assembly can move along the guide slope, thereby realizing the lifting and lowering of the bending assembly, eliminating the lifting and lowering drive of the bending assembly, making the design of the entire forming mechanism more reasonable and the forming mechanism occupies less space.

[0010] A further technical solution of the utility model is: the bending assembly includes a lifting block, a spring, a mounting plate and a connecting seat, the lifting block passes through the connecting seat and is connected to the mounting plate by the spring, and a roller that can move along the guide slope is provided at one end of the mounting plate away from the spring.

[0011] During the movement of the movable seat, the roller slides along the guide slope, causing the position of the mounting plate to rise and fall, thereby the lifting block connected by the spring moves up and down to lift the crease of the lining to ensure the correct direction of the crease of the lining; after the lining is formed, the movable seat returns to its position, and at the same time, the bending assembly returns to its position under the action of the spring to avoid interference when the lining enters the forming mechanism.

[0012] A further technical solution of the utility model is that the lifting block comprises a conical lifting end and a connecting end connected to a spring.

[0013] When the lining is formed, the lifting end contacts the lining, so that the lining is folded in the correct direction; the lifting end of the lifting block is tapered to reduce the contact area, which can effectively avoid the displacement of the lining caused by the lifting block during the lifting of the bending component, thereby avoiding affecting the positioning accuracy.

[0014] A further technical solution of the utility model is: the connecting seat is connected to the fixed seat, and the guiding inclined surface is connected to the movable seat.

[0015] The bending assembly is connected to the fixed seat through the connecting seat, and the guiding inclined surface is connected to the movable seat. The guiding inclined surface can be driven to move during the movement of the movable seat, so that the bending assembly moves along the guiding inclined surface to achieve lifting and lowering.

[0016] A further technical solution of the utility model is that the fixing mechanism comprises a baffle and a pressing member, wherein the baffle is arranged outside the fixed seat and the movable seat, and the pressing member is arranged above the fixed seat and / or the movable seat.

[0017] The fixing mechanism partially limits the surroundings and the upper and lower parts of the liner, and fixes the part that does not fold during the liner molding; it ensures that the liner will not be displaced during the liner molding, and ensures the qualified rate of the liner molding.

[0018] A further technical solution of the utility model is: the clamping piece is connected to the movable seat and / or the fixed seat through a mounting seat, the clamping piece includes a lifting drive, a pressure block and a connecting rod, one end of the pressure block is placed above the movable seat and / or the fixed seat, the other end of the pressure block is movably connected to the lifting drive, one end of the connecting rod is hinged to the pressure block and the other end is hinged to the mounting seat.

[0019] When the liner enters the molding mechanism, in order to avoid interference from the clamping piece, the clamping piece can be driven by the lifting movement to make the pressing block rotate along the connecting rod. The pressing block rotates to the side of the movable seat and / or the fixed seat, and the liner can smoothly enter the molding mechanism; when the liner needs to be clamped, the lifting drive moves in the opposite direction to press the liner and complete the clamping action.

[0020] A further technical solution of the utility model is that the blocking piece is arc-shaped.

[0021] The arc-shaped baffle facilitates the lining to enter the forming mechanism and has a certain guiding effect.

[0022] A further technical solution of the utility model is that a side of the movable seat away from the fixing mechanism is connected to a linear drive, and the linear drive is used for the movable seat to move.

[0023] The linear drive drives the movable seat to move in a direction close to the fixed seat or away from the fixed seat.

[0024] A further technical solution of the utility model is that both the fixed seat and the movable seat are provided with suction cups for sucking the lining.

[0025] The suction cups on the fixed seat and the movable seat can take materials from the silo and fix the liner during molding.

[0026] The utility model also provides a system for adding lining to a packaging box, comprising a lining paper material bin, a transfer mechanism, the lining molding mechanism and a material taking mechanism, wherein the lining molding mechanism is arranged on the transfer mechanism, and the lining molding mechanism cooperates with the transfer mechanism to remove the lining in the lining paper material bin and then mold it, and the material taking mechanism is used to place the molded lining in the packaging box.

[0027] The beneficial effects of the utility model are as follows: the lining of the utility model is placed on a fixed seat and a movable seat, and then fixed by a fixing mechanism. During molding, the movable seat is moved so that the lining is folded along the crease. During this molding process, a lifting and lowering bending component is arranged between the fixed seat and the movable seat to ensure that the lining is folded in the correct direction. The qualified rate of the lining molding is high, ensuring the smooth progress of the subsequent processes.

[0028] After the manipulator with the liner forming mechanism takes material from the liner paper silo, the manipulator forms the liner paper through the liner forming mechanism during the liner transfer process. When the manipulator moves to the position where it docks with the material taking mechanism, the liner paper is also formed, and the material taking mechanism takes the formed liner paper into the packaging box. In this process, the forming mechanism can be directly connected to the manipulator, and the liner forming can be completed when the manipulator takes the liner from the silo and transfers it to the material taking mechanism, which greatly improves work efficiency.

[0041] The lining is placed on a fixed seat and a movable seat, and then fixed by a fixing mechanism. During molding, the lining is folded along the crease by moving the movable seat. During this molding process, a lifting and lowering bending component is arranged between the fixed seat and the movable seat to ensure that the lining is folded in the correct direction.

The movable seat 2 can move in a direction close to or away from the fixed seat 1 so that the bending assembly 5 can be lifted and lowered along the guide slope.

[0043] The guide slope is arranged between the fixed seat and the movable seat. During the movement of the movable seat, the bending assembly can move along the guide slope, thereby realizing the lifting and lowering of the bending assembly, eliminating the lifting and lowering drive of the bending assembly, making the design of the entire forming mechanism more reasonable and the forming mechanism occupies less space.

[0044] In this embodiment, the bending assembly 5 includes a lifting block 51, a spring 53, a mounting plate 54 and a connecting seat 52. The lifting block 51 passes through the connecting seat 52 and is connected to the mounting plate 54 via the spring 53. The mounting plate 54 is provided with a roller 55 that can move along the guide slope 4 at one end away from the spring 53.

[0045] During the movement of the movable seat, the roller slides along the guide slope, causing the position of the mounting plate to rise and fall, thereby the lifting block connected by the spring moves up and down to lift the crease of the lining to ensure the correct direction of the crease of the lining; after the lining is formed, the movable seat returns to its position, and at the same time, the bending assembly returns to its position under the action of the spring to avoid interference when the lining enters the forming mechanism.

One end of the connecting rod 323 is hinged to the pressure block 322 and the other end is hinged to the mounting seat.

[0055] When the liner enters the molding mechanism, in order to avoid interference from the clamping piece 32, the clamping piece 32 can be driven by the lifting drive 321 to make the pressing block 322 rotate along the connecting rod 323, and the pressing block 322 rotates to the side of the movable seat 2 and / or the fixed seat 1, so that the liner can smoothly enter the molding mechanism; when the liner needs to be clamped, the lifting drive 321 moves in the opposite direction to press the liner and complete the clamping action.

[0056] In this embodiment, the pressing member 32 moves synchronously with the movable seat 2 .

[0057] In this embodiment, the lifting drive 321 is a thin cylinder.

[0058] In this embodiment, the blocking piece 31 is arc-shaped.

[0059] The arc-shaped baffle 31 facilitates the liner to enter the molding mechanism and has a certain guiding effect.

[0060] In this embodiment, the top end of the blocking piece 31 is in an arc shape extending outward, so as to avoid interference with the liner when it enters the molding structure and play a guiding role.

[0067] Embodiment 2:

[0068] A system for adding lining to a packaging box comprises a lining paper material bin 8, a transfer mechanism 9, the lining molding mechanism of the first embodiment and a material taking mechanism 10, wherein the lining molding mechanism is arranged on the transfer mechanism 9, and the lining molding mechanism cooperates with the transfer mechanism 9 to remove the lining 0 in the lining paper material bin 8 and then mold it, and the material taking mechanism 10 is used to place the molded lining in the packaging box.

[0069] After the manipulator with the liner forming mechanism takes material from the liner paper silo, the manipulator forms the liner paper through the liner forming mechanism during the liner transfer process. When the manipulator moves to the position where it docks with the material taking mechanism, the liner paper is also formed, and the material taking mechanism takes the formed liner paper into the packaging box. In this process, the forming mechanism can be directly connected to the manipulator, and the liner forming can be completed when the manipulator takes the liner from the silo and transfers it to the material taking mechanism, which greatly improves work efficiency.

The side edges of the liner are fixed by the baffle 31. In the process of the manipulator moving to the stop position, the thin air claw moves toward the middle at the same time, driving the movable seat 2 to retract. At the same time, the guide slope 4 connected to the movable seat 2 forces the bending assembly to climb, driving the lifting block to rise vertically, and assisting the forming of the top angle of the liner. When the liner is formed, the manipulator moves to the stop position, waiting for the material picking mechanism to remove the liner, and then moves to the material picking position. At the same time, the two ends of the thin air claw move outward to the initial position at the same time, and the bending assembly returns to the initial position using the reset spring to start the next working cycle.
