Technical Field

[0001] The utility model relates to a pressing roller, in particular to a pressing roller with adjustable height. Background Art

[0002] The pressing roller is a kind of equipment widely used in many industrial fields. Its main function is to realize various processing processes by applying pressure to materials, such as calendering, embossing, laminating, etc. of materials such as paper and plastic film. The pressing roller is usually made of metal or rubber and its surface is specially treated to have good wear resistance, corrosion resistance, high temperature resistance and other properties to ensure long-term and stable service life. In paper product processing, the pressing roller is mainly used for calendering, compacting, laminating and other processes of paper, which can improve the surface finish, strength, smoothness and other properties of paper. In plastic film processing, the pressing roller is used to realize the calendering, embossing, laminating and other operations of the film to produce plastic products with various thicknesses, textures and properties;

Since the properties and thickness of the materials may differ, when the thickness of the materials changes, the height of the pressing roller cannot be adjusted, resulting in the inability to accurately control the pressure during the processing, leading to poor processing results or even no processing, thereby reducing the utilization rate of the equipment.

There is a second bevel gear 1022, a screw rod 103 is fixedly installed in the second bevel gear 1022, the other end of the screw rod 103 is rotatably connected to the side wall of the lower end of the frame 1, a nut is slidably installed on the screw rod 103, a lifting plate 104 is fixedly installed on the outer side of the nut, and a movable roller mechanism 2 is fixedly installed on one side of the lower surface of the lifting plate 104. The movable roller mechanism 2 is arranged on the upper end of the fixed roller 101, and the rotating shaft 102 drives the screw rod 103 to rotate, so that the nut drives the lifting plate 104 to move up and down, which is used to adjust the height of the movable roller mechanism 2 based on the fixed roller 101;

[0021] A counterweight 1041 is fixedly mounted on the other side wall of the lower surface of the lifting plate 104 , and the counterweight 1041 is used to balance the vertical gravity of the lifting plate 104 to prevent the lifting plate 104 from being damaged due to uneven force on the lifting plate 104 .

[0022] A top plate 105 is fixedly installed on the upper end of the frame 1, and bearings 1051 are fixedly installed on both ends of the upper surface of the top plate 105 and both ends of the upper surface of the lower end of the frame 1. The screw rod 103 is fixedly installed in the bearings 1051, and the two ends of the screw rod 103 are respectively fixed by the bearings 1051, thereby fixing the position of the screw rod 103 to prevent the screw rod 103 from being displaced during use, resulting in loosening of the engagement between the first bevel tooth 1021 and the second bevel tooth 1022, thereby further preventing damage to the screw rod 103.

[0023] The movable roller mechanism 2 includes a movable plate 201, which is arranged on one side of the lower surface of the lifting plate 104. The limiting shafts 202 are fixedly installed at the four corners of the upper surface of the movable plate 201. The limiting shafts 202 are slidably connected to the lifting plate 104. Sliders are fixedly installed at both ends of the side walls of both sides of the lifting plate 104. Linear rails are installed at both ends of the side walls of both sides of the frame 1. The sliders are slidably installed on the linear rails for guiding the movement of the lifting plate 104 through the linear rails and supporting the lifting plate 104 at the same time, thereby ensuring the balanced shape of the lifting plate 104, thereby reducing the friction between the nut and the screw rod 103 caused by the lifting plate 104, and improving the service life of the screw rod 103.

At this time, the second bevel gear 1022 will drive the screw rod 103 to rotate, and then the nut will drive the lifting plate 104 to move along the linear rail, and the gravity of the counterweight block 1041 is close to that of the movable roller mechanism 2, so that the force of the lifting plate 104 is uniform, and the movable roller mechanism 2 is driven to descend through the lifting plate 104. When the movable roller 203 contacts the material, the steering wheel can be continuously turned. At this time, the limit shaft 202 slides at the four corners of the lifting plate 104, and the movable plate 201 will approach the lifting plate 104, and the second spring will be compressed. After the pressure between the movable roller 203 and the fixed roller 101 is adjusted to a reasonable level, the motor is started, the fixed roller 101 will rotate, and drive the movable roller 203 to rotate, and the material to be processed is processed by the rotation of the movable roller 203 and the fixed roller 101.
