Description

Technical Field

[0001] The utility model relates to the technical field of paper mounting machines, in particular to a paper pressing mechanism. Background Art

[0002] The invention relates to a paper mounting machine, which belongs to the field of paper making machinery, and in particular to a paper mounting machine for pasting two sheets of paper together. The paper mounting machine is composed of a paper feeding mechanism, a paper mounting mechanism and a paper pressing mechanism. Two air heads are arranged in parallel on the paper feeding mechanism, and an intermediate positioning mechanism is arranged on the paper mounting mechanism to divide the paper mounting mechanism into two paper paths. Wing-shaped spring sheets are arranged on both sides of the paper mounting mechanism. The intermediate positioning mechanism is composed of an intermediate positioning guide block and a lifting mechanism, and has a simple structure.

[0003] After searching, a Chinese patent discloses a paper pressing mechanism for a paper laminating machine (authorization announcement number CN212949493U), which includes a supporting and conveying mechanism and a flattening mechanism. The flattening mechanism is fixedly installed at the upper end of the supporting and conveying mechanism. When the degree of compaction needs to be adjusted, the internal thread screw locking ring is loosened, and then the distance between the first flattening roller and the motor-driven conveyor belt is adjusted. After adjustment, the internal thread screw locking ring is tightened again to make the internal thread screw locking ring and the limit block in close contact with the support block to achieve a clamping effect, so that the adjusted height of the first flattening roller is fixed. When the distance between the first flattening roller and the motor-driven conveyor belt is smaller, the compaction is tighter, and the distance between the first flattening roller and the motor-driven conveyor belt is larger, the compaction is looser. Although this patented technology can re-compact the pre-compacted paper through the second flattening roller to prevent the pre-compacted paper from loosening during transportation, it also makes the compaction more firm.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that the paper pressing structure of the above paper mounting machine cannot be automatically adjusted according to the thickness of the paper. The paper pressing structure needs to be debugged before operation can be carried out, which not only increases the workload of the staff, but also affects the work efficiency. Utility Model Content

[0011] By adopting the above technical solution, through the coordinated use of the telescopic sleeve and the telescopic rod, a certain supporting effect can be exerted on the limit member, so that the limit member is relatively stable during the adjustment process.

[0012] As a preferred embodiment, a monitoring component is provided inside the rack, and the monitoring component includes a PLC controller fixedly mounted on one side of the rack, and infrared sensors are embedded in the sides of the two limit members that are close to each other.

In the present invention, the distance between the limiter and the paper can be monitored through the infrared sensor, and the information is transmitted to the PLC controller, which then automatically controls the extension stroke of the cylinder and uses the limiter to limit the paper to a certain extent, thereby preventing the paper from deflecting during transportation.

A conveyor belt 5 is connected between the two transmission rollers 4. Installation boxes 15 are provided on both sides of the inner wall of the frame 1. The interior of the installation box 15 is fixedly connected to a fixed rod 16. A sliding member 18 is slidably installed inside the installation box 15.

A paper pressing shaft 12 is fixedly installed between the two slides 18. The outer side of the paper pressing shaft 12 is rotatably connected to four When paper mounting is required, the driving source can be used to drive the rotating shaft 3 to rotate, thereby driving the rotation of multiple transmission rollers 4, and then the conveyor belt 5 can be used to transport multiple papers. When the transported paper contacts the pressure wheel 13 on the paper pressing shaft 12, the spring 17 generates a reaction force by its own elastic force, which will push the corresponding sliding member 18 to slide in the installation box 15, and prompt the pressure wheel 13 to automatically lift according to the thickness of the paper, and then press the two papers pasted together, so that during the transportation process, the two papers pasted together are more firmly pasted and the effect is better.

[0031] Specifically, a limit assembly is provided inside the frame 1, and the limit assembly includes a cylinder 6 fixedly mounted on both sides of the frame 1. Two limit members 7 are provided inside the frame 1. The piston rods of the cylinders 6 all pass through the interior of the frame 1 and are fixedly connected to the corresponding limit members 7. The limit assembly also includes a telescopic sleeve 9 fixedly connected to the outside of the frame 1 and located on both sides of the cylinder 6. A telescopic rod 8 is slidably mounted inside the telescopic sleeve 9. The telescopic rod 8 passes through the interior of the frame 1 and is fixedly connected to the limit members 7. The coordinated use of the telescopic sleeve 9 and the telescopic rod 8 can provide a certain support for the limit members 7. The supporting effect makes the limit member 7 more stable during the adjustment process. A monitoring component is provided inside the frame 1, and the monitoring component includes a PLC controller 2 fixedly installed on one side of the frame 1. The two limit members 7 are close to each other on both sides and are embedded with infrared sensors 10. Through the action of the infrared sensor 10, the distance between the limit member 7 and the paper can be monitored, and the information is transmitted to the PLC controller 2. Then the PLC controller 2 automatically controls the extension stroke of the cylinder 6, and uses the limit member 7 to play a certain limiting role on the paper to avoid the paper from deflecting during the transportation process.

[0032] Specifically, a servo motor 11 is fixedly installed on the outside of the frame 1, and the output shaft of the servo motor 11 extends to the inside of the frame 1 and is fixedly connected to one of the rotating shafts 3.

The cylinder 6, infrared sensor 10 and servo motor 11 are all electrically connected to the PLC controller 2, and the cylinder 6, infrared sensor 10 and servo motor 11 can be controlled to start and stop by the PLC controller 2.

[0033] Working principle: First, when paper mounting is required, the pasted papers can be placed on the conveyor belt 5, and the servo motor 11 can be started by the PLC controller 2 to drive the rotation of the shaft 3 and multiple transmission rollers 4, so that the conveyor belt 5 can be used to transport multiple papers. The infrared sensor 10 can monitor the distance between the limiter 7 and the paper, and transmit the information to the PLC controller 2. Then, the PLC controller 2 automatically controls the extension stroke of the cylinder 6, and uses the limiter 7 to limit the paper to a certain extent, so as to avoid the paper from being stuck in the transportation process. The offset phenomenon occurs, and the coordinated use of the telescopic sleeve 9 and the telescopic rod 8 can provide a certain support for the limiter 7, so that the limiter 7 is relatively stable during the adjustment process. Then, when the conveyed paper contacts the pressure wheel 13 on the paper pressing shaft 12, the spring 17 generates a reaction force by its own elastic force, which pushes the corresponding sliding member 18 to slide in the installation box 15, and prompts the pressure wheel 13 to automatically rise according to the thickness of the paper, and then can press the two sheets of paper pasted together, so that the two sheets of paper pasted together are more firmly pasted during transportation.
