Description

Technical Field

[0001] This utility model relates to the field of unwinding devices for membrane substrates, and more specifically, to an automatic correction and unwinding device for textured membrane substrates. Background Technology

[0002] The anilox film substrate unwinding machine is a key piece of equipment in coating and printing production lines. It is mainly used to smoothly release rolls of anilox film substrate (such as PET, PE, etc.). Through constant tension control, a correction system and an automatic feeding device, it ensures that the substrate is continuously transported without wrinkles or deviation. Its structure usually includes an air shaft, a correction roller and a PLC control system. It is suitable for processing precision materials such as optical films and release films. It is characterized by high efficiency, stability and high degree of automation, which can significantly improve production efficiency and material utilization.

[0003] Existing reticulated film substrate unwinding machines typically use photoelectric sensors to detect the edge position of the film and achieve automatic correction control. If the sensor probe is blocked by dust, adhesive residue or splashes, it will cause signal distortion or failure, causing the correction system to misjudge the amount of film offset and causing the substrate to run off-track.

[0010] Preferably, a movable block is fixedly connected to the bottom end of the connecting rod, a stabilizing frame is fixedly connected to the bottom of the upper support, and the bottom end of the stabilizing frame is fixedly connected to the lower support.

[0011] Preferably, the stabilizer is slidably connected to the moving block through it, a spring is sleeved on the stabilizer, and an air outlet pipe is fixedly installed at the top of the air storage pipe.

[0014] The beneficial effects of this utility model are: when the motor drives the transmission shaft to unwind, it also drives the wheel to rotate through the rotating shaft, causing the lever to push the moving block to move downward, so that the air storage tube can draw in air and store force for the spring to stretch. When the lever moves to separate from the moving block, the spring instantly rebounds and resets, so that the air inside the air storage tube is squeezed out and blown onto the sensor probe, preventing the sensor from being blocked by foreign objects and causing signal distortion.

The inner side wall of the outer cover 3 is rotatably connected to the rotating shaft 16, which is connected to the output shaft of the motor 13 via the second belt 15.

The auxiliary shaft 10 is located directly above the drive shaft 9. The auxiliary shaft 10 and the drive shaft 9 are used to extrude the film layer of the roll material 7. The top of the outer cover 3 is fixedly connected to the control console 11.

[0023] The jet assembly includes a wheel 17 fixedly mounted on a rotating shaft 16. A lever 18 is fixedly connected to the side wall of the wheel 17, and the lever 18 is eccentrically positioned on the wheel 17. An upper support 19 and a lower support 20 are fixedly connected to the inner side wall of the outer cover 3. An air storage pipe 21 is fixedly connected to the upper support 19. A connecting rod 22 is slidably arranged inside the air storage pipe 21. A piston is fixedly connected to the top of the connecting rod 22 inside the air storage pipe 21, and a moving block 23 is fixedly connected to the bottom of the connecting rod 22. A stabilizing frame 24 is fixedly connected to the bottom of the upper support 19, and the bottom of the stabilizing frame 24 is connected to... The lower bracket 20 is fixedly connected, the stabilizer 24 passes through the moving block 23 and is slidably connected to the moving block 23, the stabilizer 24 is fitted with a spring 25, the top end of the gas storage pipe 21 is fixedly installed with an air outlet pipe 26, the end of the air outlet pipe 26 passes through the outer cover 3 and corresponds to the probe position on the sensor 12, the top end of the spring 25 is fixedly connected to the upper bracket 19, the bottom end of the spring 25 is fixedly connected to the moving block 23, the support plate 2 and the outer wall of the outer cover 3 are fixedly connected, and multiple feet 4 are fixedly connected to the bottom of the support plate 2 and the outer cover 3, and the feet 4 are fixedly connected to the base 1.

[0024] The working principle of the automatic correction and unwinding device for textured film substrate is as follows: by starting the motor 13, the output shaft of the motor 13 drives the transmission shaft 9 to rotate through the first belt 14. The transmission shaft 9 and the auxiliary shaft 10 squeeze the film layer of the roll 7, and the film layer of the roll 7 is transferred by friction, thereby realizing the unwinding action. The output shaft of motor 13 also drives shaft 16 to rotate via second belt 15, which in turn drives wheel 17 to rotate and lever 18 to make circular motion. The trajectory of lever 18 passes through moving block 23, pushing moving block 23 downward, which in turn drives connecting rod 22 and piston at its top to move downward. At this time, negative pressure is formed inside air storage tube 21, and external air is drawn into the air storage tube 21 through air outlet tube 26. At the same time, spring 25 is stretched and stored by moving block 23. When lever 18 moves to separate from moving block 23, spring 25 instantly rebounds and resets, driving moving block 23 to move upward. The piston on connecting rod 22 instantly squeezes the air inside air storage tube 21, causing air to be ejected from the end of air outlet tube 26 and blown onto the probe of sensor 12, preventing sensor 12 from being blocked by foreign objects and causing signal distortion.

[0025] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
