Description

Technical Field

[0001] The utility model relates to the technical field of cigarette packaging machinery and equipment, in particular to an aluminum foil paper lubricating oil supply system with a feedback function. Background Art

[0002] In the cigarette packaging process, the ZB45 small box packaging machine needs to apply lubricating oil to the aluminum foil paper strip loaded into the machine in real time to improve the ductility of the aluminum foil paper, so as to meet the packaging process requirements. The application of the aluminum foil paper lubricating oil is to store the lubricating oil in an oil cup with a capacity of 1L. The lubricating oil in the oil cup flows into the aluminum foil paper lubricating felt through a oil pipe, and is applied to the surface of the aluminum foil paper strip through the lubricating felt. In the actual production process, the oil volume in the oil cup cannot be monitored. Often, after the oil in the oil cup is used up, the lubricating oil is not added in time, resulting in insufficient lubrication of the aluminum foil paper, so that the aluminum foil paper cannot meet the processing process requirements, and further leading to frequent equipment shutdowns and quality defects of cigarette packs such as poor folding of the aluminum foil paper of the cigarette pack, seriously affecting the product quality and production efficiency. Content of the Utility Model

[0033] As Figure 1 shown in Figure 2 and

[0034] Preferably, an embodiment of the present utility model provides an aluminum foil lubricating oil supply system with a feedback function. The system mainly includes an oil cup 1, a primary oil pipe 12, an oiling felt 8, a hollow metal ball 2, an inductive proximity switch sensor 13, a photoelectric sensor 3, a PLC controller 5, a stop relay 7, a positive pressure air pipe 15, and a reversing valve 4. Figure 1 and Figure 2 Please continue to refer to

[0035] The oil cup 1 is a cylindrical cavity with a volume of 1 L, and its bottom is hemispherical. The oil cup 1 is used to store the lubricating oil 16 for lubricating the aluminum foil. A mounting bracket 14 is fixed on the side of the oil cup 1, and the oil cup 1 can be installed and fixed on the packaging machine equipment by screws. The top of the oil cup 1 is a circular sealing cover 19, and the sealing cover 19 is threadedly connected to the oil cup 1 for easy disassembly and assembly. A top cylindrical interface 17 with an inner diameter of 6 mm is provided at the center of the sealing cover 19, and a bottom cylindrical interface 18 with an inner diameter of 8 mm is provided at the center of the bottom of the oil cup 1.

[0036] The PLC controller 5 includes modules such as a CPU module, a digital input module, a digital output module, and a power module, which are used to receive signals sent by sensors and output control signals to control the reversing valve 4 and the stop relay 7.

[0037] The outer diameter of the first-stage oil pipe 12 is 8 mm. One end of it is hermetically connected to the cylindrical interface 18 at the bottom of the oil cup, and the other end is connected to two second-stage oil pipes 11 through a three-way interface. The other ends of the two second-stage oil pipes 11 are connected to two oil inlet holes of the reversing valve 4.

[0038] The positive-pressure air pipe 15 is an air pipe with an outer diameter of 6 mm. One end of it is hermetically connected to the cylindrical interface 17 at the top of the oil cup 1, and the other end is connected to the compressed air supply air path of the packaging machine. Compressed air enters the oil cup 1 through the positive-pressure air pipe 15 to apply pressure to the oil liquid inside the oil cup 1.

[0039] There are two oiling felts 8. The oiling felts 8 are cuboids made of felt material with a length equal to the width of the aluminum foil. A certain amount of lubricating oil can be stored inside. One side of the outer surface is in contact with the aluminum foil to apply the lubricating oil to the surface of the aluminum foil. The oiling felts 8 are hermetically connected to two oil outlet holes of the reversing valve 4 through two third-stage oil pipes 9.

[0040] The first-stage oil pipe 12, the second-stage oil pipe 11, and the third-stage oil pipe 9 have the same diameter and material.

[0041] The material of the oil cup 1 is made of transparent plexiglass material for observing the oil volume inside the oil cup. There is a movable hollow metal ball 2 inside the oil cup 1. When the lubricating oil 16 is contained in the oil cup 1, the hollow metal ball 2 floats on the lubricating oil liquid surface. An inductive proximity switch sensor 13 capable of sensing metal is installed at the bottom of the oil cup 1. When the lubricating oil in the oil cup 1 is exhausted, the hollow metal ball 2 will contact the inductive proximity switch sensor 13, and then the inductive proximity switch sensor 13 generates a high-level signal and transmits it to the PLC controller 5.

[0042] A photoelectric sensor 3 is also installed near the intersection line of the hemisphere and the cylinder at the bottom of the oil cup 1 to perform real-time detection on the lubricating oil 16 inside the oil cup 1. When the oil liquid is lower than the detection range of the photoelectric sensor 3, the photoelectric sensor 3 generates a high-level signal and transmits it to the PLC controller 5.

[0043] The inductive proximity switch sensor 13 and the photoelectric sensor 3 are respectively connected to the digital input module of the PLC controller 5 through wires 20. When the inductive proximity switch sensor 13 or the photoelectric sensor 3 is triggered, a high-level signal is transmitted to the PLC controller 5. The left and right electromagnetic coils 10 of the reversing valve 4 are respectively connected to the digital output module of the PLC controller 5 through wires 20. The PLC controller 5 transmits a control signal to the electromagnetic coil 10 through the wire 20 to control the reversing of the reversing valve 4.

[0044] The digital output module of the PLC controller 5 is connected to the human-machine interaction system 6 through a wire 20. The human-machine interaction system 6 can directly use the human-machine interaction system of the packaging machine, that is, share the human-machine interaction system. When the photoelectric sensor 3 detects that the lubricating oil 16 is lower than the detection range, the PLC controller 5 outputs and displays the message "Insufficient lubricating oil for aluminum foil paper" on the human-machine interaction system 6 to remind the operator to add lubricating oil 16 in time. The digital output module of the PLC controller 5 is connected to the stop relay 7 through a wire. The stop relay 7 is used for application to the packaging machine or shares the stop relay of the packaging machine. When the inductive proximity switch sensor 13 detects that the lubricating oil 16 in the oil cup 1 is exhausted, the PLC controller 5 disconnects the stop relay 7, thereby stopping the packaging machine and outputting and displaying the message "Lubricating oil for aluminum foil paper exhausted" on the human-machine interaction system 6.

[0045] The working principle of a lubricating oil supply system for aluminum foil paper with a feedback function of the present utility model is as follows: The photoelectric sensor 3 monitors the oil level in the oil cup 1 in real time. When a certain amount of lubricating oil 16 is detected, the photoelectric sensor 3 outputs a low level. When the lubricating oil 16 level is lower than the detection range of the photoelectric sensor 3, the photoelectric sensor 3 cannot detect the lubricating oil 16 and outputs a high-level signal to the PLC controller 5. After receiving the signal, the PLC controller 5 outputs a signal to the human-machine interaction system 6, and the message "Insufficient lubricating oil for aluminum foil paper" is output and displayed on the human-machine interaction system 6 to remind the operator to add lubricating oil 16 in time. If the operator does not add oil after the insufficient oil quantity signal is generated and continues to use it until the lubricating oil 16 in the oil cup 1 is exhausted, at this time, the hollow metal ball 2 will reach the lowest position and contact the inductive proximity switch sensor 13. The inductive proximity switch sensor 13 generates a high-level signal and transmits it to the PLC controller 5. The PLC controller 5 disconnects the stop relay 7 used for the packaging machine, thereby stopping the packaging machine and outputting and displaying the message "Lubricating oil for aluminum foil paper exhausted" on the human-machine interaction system 6. Through the above solution, it can timely remind the operator to add lubricating oil and stop the machine in time after the lubricating oil is used up, avoiding the quality defect of poor folding of aluminum foil paper caused by insufficient lubrication of aluminum foil paper, and ensuring the product quality and the production efficiency of the packaging machine.

[0046] In addition, two aluminum foil rolls, one on the left and one on the right, are installed on the packaging machine. Only one aluminum foil roll is used in production, and the other is for standby. The two oiled felts 8 in the present utility model can respectively apply oil to the left and right aluminum foil rolls. When the left aluminum foil roll is used on the packaging machine, the PLC controller 5 energizes the electromagnetic coil 10 on the left side of the reversing valve 4, and the lubricating oil 16 flows into the three-stage oil pipe 9 on the left to supply oil to the oiled felt 8 on the left, while the three-stage oil pipe 9 and the oiled felt 8 on the right are not supplied with oil at this time. Conversely, when the right aluminum foil roll is used on the packaging machine, the system only supplies oil to the three-stage oil pipe 9 and the oiled felt 8 on the right.

[0047] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
