Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to an automatic correction device for a film calendering machine. Background Technology

[0002] A film calender is a specialized piece of machinery used to produce film materials. During operation, it features automatic deviation correction, effectively ensuring production stability and high product quality. Through advanced technology and a precise control system, this equipment can monitor and adjust material positional deviations in real time during film processing, thereby preventing product quality issues caused by misalignment.

[0003] However, existing automatic correction devices typically use an adjustable table mounted on a crossbeam, with a photoelectric sensor installed on the table, which is locked with screws. When the film is being wound, the screws need to be loosened to move the table to avoid the film, and the position of the photoelectric sensor needs to be reconfirmed afterward. At the same time, when the machine is stopped, the photoelectric sensor is exposed. Therefore, it is necessary to design an automatic correction device for a film calender. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an automatic deviation correction device for a thin film calender.

[0005] The objective of this utility model can be achieved through the following technical solution: An automatic correction device for a film calender includes a frame, on which an adjustment shaft is vertically rotatably mounted. The lower end of the adjustment shaft is connected to a drive module, and the upper end of the adjustment shaft is fixedly connected to the middle of a swing frame. A correction roller group is horizontally rotatably mounted on the swing frame. The device is characterized in that a crossbeam is fixedly connected to the frame via an mounting block, and an adjustment platform is slidably connected to the crossbeam. A locking screw is threaded onto the adjustment platform. The adjustment platform is connected to an intermediate guide seat, and the intermediate guide seat is connected to a protective box. A middle rod is horizontally slidably connected to the intermediate guide seat, and a second locking screw is threaded onto the intermediate guide seat. A stop block is fixedly connected to one end of the middle rod, and a limiting member is fixed to the other end of the middle rod. An auxiliary rod is horizontally slidably connected to the protective box. One end of the auxiliary rod has a handle, and the other end of the auxiliary rod is connected to a connecting member, which can abut against the limiting member. The connecting member and the limiting member are detachably connected via a quick clamp. A photoelectric sensor is also installed on the connecting member.

[0006] The protective box has a door that slides vertically on one side. The door has a handle at the top and a positioning iron plate at the bottom. The protective box is equipped with a magnet that cooperates with the positioning iron plate.

[0007] Both the first and second locking screws are hand-tightened parts.

[0008] The frame also has a horizontally rotating guide roller, and the guide roller, crossbeam and correction roller group are arranged in sequence from front to back.

[0009] Compared with existing technologies, this automatic web-correcting device for a film calender has the following advantages: In this invention, during the initial preparation or shutdown, the photoelectric sensor can be placed inside the protective box by releasing the quick clamp and being driven by the auxiliary rod. During normal testing, simply pull the auxiliary rod to make the connecting part and the limiting part abut against each other, and lock them together with the quick clamp. At this time, the photoelectric sensor can quickly be in the normal working position, which greatly improves the convenience of operation and provides better protection for the photoelectric sensor.

[0011] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0012] like Figures 1-5As shown, the automatic correction device for this film calender includes a frame 1. A control shaft 4 is vertically rotatably mounted on the frame 1. The lower end of the control shaft 4 is connected to a drive module. In this embodiment, the drive module adopts an existing structure. After the photoelectric sensors 6 on both sides detect the corresponding information, they can transmit the signal to the control host, causing the drive module to move. The swing frame 5 rotates at the corresponding angle to complete the automatic correction of the film. This is achieved using existing technology. The upper end of the control shaft 4 is fixedly connected to the middle of the swing frame 5. A correction roller group 3 is horizontally rotatably mounted on the swing frame 5. A crossbeam 11 is fixedly connected to the frame 1 via a mounting block 7. An adjustment table 9 is slidably connected to the crossbeam 11. A locking screw 8 is threadedly connected to the adjustment table 9. The adjustment table 9 is connected to an intermediate guide seat 10. The intermediate guide seat 10 is connected to a protective box 17. One side of the protective box 17 has The protective box 17 has an opening and a through hole on the other side. A middle rod 12 is horizontally slidably connected to the middle guide seat 10. A locking screw 21 is threaded onto the middle guide seat 10. A stop block 20 is fixed to one end of the middle rod 12, and a limiting member 13 is fixed to the other end of the middle rod 12. An auxiliary rod 18 is horizontally slidably connected to the protective box 17. One end of the auxiliary rod 18 has a handle 19, and the other end of the auxiliary rod 18 is connected to the connecting member 16. The connecting member 16 can abut against the limiting member 13. With this structure, the adjustment table 9 can quickly and initially adjust the position of the photoelectric sensor 6, while the middle rod 12 can make a secondary small-range adjustment to the position of the photoelectric sensor 6. The connecting member 16 and the limiting member 13 are detachably connected by a quick clamp 14, which is an existing product.
