Description

Technical Field

[0001] This utility model relates to the field of calendering technology, specifically to a pressure-adjustable calendering machine. Background Technology

[0002] Calenders are widely used in industries such as textiles, leather, and nonwovens. They are mainly used to make the surface of materials smooth and flat by mechanical pressure and temperature treatment, and to improve their gloss and feel.

[0003] Calenders primarily utilize the combination of heated rollers and pressure rollers to treat the surface of fabrics. In this case, to process both sides of the fabric, a secondary rolling process is often required. Different pressures are needed for different fabrics, and the pressure must be kept constant during the two rolling processes of the same fabric. Therefore, a calender with adjustable pressure needs to be designed. To quickly adjust the pressure to the same level, a synchronous movement structure needs to be set up between multiple pressure rollers to ensure pressure uniformity. Utility Model Content

[0004] The purpose of this invention is to provide a pressure-adjustable calendering machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes an outer support frame, a heating roller mounted on the front side of the outer support frame, and pressure rollers mounted above and below the heating roller. A fixed frame is fixed on the front side of the outer support frame at both ends of the heating roller. A drive motor for rotating the heating roller is disposed on the outside of the fixed frame. A movable frame is mounted on the front side of the outer support frame at both ends of the pressure roller. The movable frame is slidably connected to the front side of the outer support frame. Synchronous drive components for lifting and lowering the movable frame are disposed on both sides of the outer support frame. A guide roller is mounted in front of the fixed frame, and a buffer component is disposed on the guide roller.

[0006] Preferably, the synchronous drive assembly includes a lifting block and end bearing seats. The end bearing seats are fixed on both sides of the outer support and are symmetrically distributed. A bidirectional lead screw is installed between the end bearing seats on the same side. The lifting block is fixed on the movable frame and located on both sides of the outer support. The bidirectional lead screw passes through the lifting block and is threadedly connected to the lifting block.

[0007] Preferably, a servo motor is fixed to the upper end of the outer bracket, and a transmission groove is provided inside the outer bracket and aligned with the upper end of the bidirectional lead screw. A transmission shaft is rotatably connected in the transmission groove. Both ends of the transmission shaft extend out of the outer bracket, and the upper end of the bidirectional lead screw extends out of the end bearing seat. Both ends of the transmission shaft and the upper end of the bidirectional lead screw are fixed with mutually meshing transmission bevel gears, and the middle position of the transmission shaft is fixed with mutually meshing drive bevel gears at the output end of the drive motor.

[0008] Preferably, the buffer assembly includes a buffer frame and a connecting rod. The buffer frame is mounted on both ends of the guide roller, the guide roller is rotatably connected between the buffer frame, and a connecting rod is installed between the buffer frame and the fixed frame.

The movable frame 31 is slidably connected to the front side of the outer support 1. Synchronous drive components 4 for driving the movable frame 31 to move up and down are provided on both sides of the outer support 1.

[0018] The synchronous drive assembly 4 includes a lifting block 41 and an end bearing seat 42. The end bearing seats 42 are fixed on both sides of the outer bracket 1 and are symmetrically distributed. A bidirectional lead screw 43 is installed between the end bearing seats 42 on the same side. The lifting block 41 is fixed on the movable frame 31 and located on both sides of the outer bracket 1. The bidirectional lead screw 43 passes through the lifting block 41 and is threadedly connected to the lifting block 41. A servo motor 46 is fixed at the upper end of the outer bracket 1. A transmission groove 45 is opened in the outer bracket 1 and aligned with the upper end of the bidirectional lead screw 43. A transmission shaft 48 is rotatably connected in the transmission groove 45. The two ends of the transmission shaft 48 extend out of the outer bracket 1. The upper end of the bidirectional lead screw 43 extends out of the end bearing seat 42. The two ends of the transmission shaft 48 and the upper end of the bidirectional lead screw 43 are fixed with mutually meshing transmission bevel gears 44. The middle position of the transmission shaft 48 and the output end of the drive motor 22 are fixed with mutually meshing drive bevel gears 47.

[0019] The buffer assembly includes a buffer frame 5 and a connecting rod 51. The buffer frame 5 is equipped with both ends of a guide roller 6, and the guide roller 6 is rotatably connected between the buffer frame 5. A connecting rod 51 is installed between the buffer frame 5 and the fixed frame 21. The front end of the connecting rod 51 is fixed on the buffer frame 5.

[0020] Working principle: First, connect the entire device to an external power source. Pass the fabric between the upper pressure roller 3 and the heating roller 2, then around the guide roller 6, and finally out between the lower pressure roller 3 and the heating roller 2. During fabric processing, the synchronous sliding of the lifting block 41 allows the pressure rollers 3 to move synchronously in opposite directions, ensuring equal pressure on both sides. The greater the range of motion of the lifting block 41, the greater the squeezing force between the pressure rollers 3 and the heating roller 2, achieving pressure regulation. During this process, the rotation of the output of the servo motor 46 is utilized, along with the drive... The drive of the moving bevel gear 47 can drive the drive shaft 48 to rotate, and then through the drive of the transmission bevel gear 44, it can drive the bidirectional lead screw 43 to rotate, which in turn drives the lifting block 41 to move in the same direction, ensuring that the pressure roller 3 moves in the same direction. When the fabric surface is processed, if the surface tension of the fabric increases, the fabric will squeeze the guide roller 6, pulling the connecting rod 51 to slide at the rear, so that the piston plate 53 slides in the pressure groove 52, compressing the gas in the pressure groove 52, achieving the purpose of buffering, and keeping the fabric tension at a reasonable level.
