Description

Technical Field

[0001] This utility model relates to the field of pressure roller technology, specifically to a pressure roller device with constant pressure. Background Technology

[0002] Pressure roller devices are frequently used in gluing machines and copper foil production lines. These devices are installed on the winding and unwinding machines. The pressure rollers on the pressure rollers press on the roll material. If the pressure is too high, the roll material will experience high resistance during traction, which can easily lead to strip breakage. If the pressure is too low, the roll material will easily unravel and the tension will be insufficient. Therefore, it is necessary to ensure that the pressure of the pressure rollers is stable when the equipment is working. Utility Model Content

[0016] The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0017] like Figures 1-3 As shown, a constant pressure roller device includes a frame 1, with the frames 1 connected by crossbeams 2. A rotating shaft 3 is connected to the frame 1 through a bearing seat. Support plates 4 are connected to both ends of the rotating shaft 3. Flanges 5 are provided on both sides of the rotating shaft 3. The support plates 4 are sleeved on the rotating shaft 3 and connected to the flanges 5. The support plates 4 rotate around the rotating shaft 3. A pressure roller 6 is connected to the end of the support plate. Pressure sensors 7 are installed on both sides of the pressure roller 6. In this embodiment, the pressure sensors 7 are spoke-type tension and pressure sensors to sense the pressure of the pressure roller 6.

[0018] A cylinder seat 8 is connected to the frame 1. A cylinder 9 is mounted on the cylinder seat 8 via a pin 1. The tail of the cylinder 9 rotates around the pin 1. The piston end of the cylinder 9 is connected to a support plate 4. A pin 2 is connected to the support plate 4. The piston end of the cylinder 9 is connected to the pin 2 via a fisheye connector 10. Support seats 11 are installed on both sides of the crossbeam 2. A lifting platform 12 is connected to the support seats 11 via a pin 3. The tail of the lifting platform 12 rotates around the pin 3. A motor 13 is mounted on one side of the frame 1 via a motor bracket. The output end of the motor 13 is connected to the lifting platform 12 via a universal joint 14. The lifting platforms 12 are connected to each other via a long drive shaft 15. Each lifting platform 12 has an input shaft and an output shaft on its two sides. The universal joint 14 is connected to the input shaft of one lifting platform 12, and the long drive shaft 15 connects the output shaft of the lifting platform 12 to the input shaft of the other lifting platform 12.

[0019] The elevator 12 is equipped with a lead screw 16, which is driven by a worm gear inside the elevator 12. A movable sleeve 17 is provided on the outside of the lead screw 16, and the movable sleeve 17 is threaded to connect with the thread on the outside of the lead screw 16. A support base 2 18 is installed on the side of the support plate 4, and a guide sleeve 19 is rotatably connected to the support base 2 18. A pin 4 is connected to the outside of the guide sleeve 19 and is connected to the support base 2 18. A key sleeve 20 is installed on the outside of the guide sleeve 19, and the movable sleeve 17 extends into the guide sleeve 19 through the key sleeve 20. A key block 21 is provided on the outside of the movable sleeve 17 and is connected to the key groove 20 on the key sleeve.

[0020] When the equipment is working, the cylinder 9 extends and controls the pressure roller 6 to press onto the tube. The key sleeve 20 on the guide sleeve 19 slides along the key block 21. As the roll diameter changes, the pressure sensor 7 detects the change in pressure of the pressure roller 6 and feeds the signal back to the motor 13. The motor 13 drives the lifting machine 12 to reverse, and the movable sleeve 17 pulls the guide sleeve 19 to move in the opposite direction, controlling the pressure of the cylinder to ensure that the force of the pressure roller 6 on the roll is constant and uniform.
