Description

Technical Field

[0001] This utility model relates to the technical field of roller changing devices, and more specifically, to a roller changing device for a calender. Background Technology

[0002] A calender is an industrial machine that presses and stretches materials into sheets. It consists of two or more rollers arranged according to the heating method and can be divided into cold pressing and hot pressing. Cold pressing is suitable for materials that do not require heating, such as graphite films, graphite sheets, microwave absorbing materials, shielding materials, magnetic materials, and non-ferrous metals. Hot pressing is further divided into water heating, electric heating, oil heating, and electromagnetic heating. Both types of machines press and stretch materials such as rubber, silicone rubber, silicone rubber, phase change materials, PTFE, or plastics into sheets of a certain thickness and surface shape at a specific temperature. They can also be used to coat fiberglass or steel wire fabric with adhesive.

[0003] In the existing technology, the replacement of rolls in calendering machines is mostly done by manually carrying the roll body to the calendering machine and then replacing it. Roll replacement is time-consuming, labor-intensive and labor-intensive. If you are not careful, the roll body may fall to the ground and damage the roll body or other equipment. In severe cases, it may even endanger the lives of the workers. Utility Model Content

[0026] Frame 1, with movable plates 2 movably embedded in the inner walls of both sides of frame 1, and mounting brackets 3 fixedly installed between the outer walls of the two movable plates 2. Mounting shafts 4 are fixedly connected between the inner walls of the two sides of mounting brackets 3, and two arc-shaped brackets 5 are rotatably sleeved on the outer surface of the mounting shafts 4; and

[0027] The height adjustment mechanism 6 includes a fixed plate 601 and a hydraulic cylinder 602. The fixed plate 601 is fixedly installed on the outer wall of the frame 1, and the hydraulic cylinder 602 is fixedly installed between the frame 1 and the outer wall of the fixed plate 601. A cross post 603 is fixedly installed at the output end of the hydraulic cylinder 602. Two sprockets 604 are rotatably sleeved on the outer surface of the cross post 603. A chain 605 is sleeved on the outer surface of each sprocket 604. The two ends of each chain 605 are respectively connected to the mounting frame 3 and the fixed plate 601.

[0028] In this embodiment, the frame 1 provides support for the mounting frame 3 and the arc-shaped bracket 5. The arc-shaped bracket 5 on the mounting frame 3 facilitates the lifting of the calender rolls. The arc-shaped bracket 5 is rotatably mounted on the mounting frame 3 via the mounting shaft 4, facilitating its flipping and storage. The hydraulic cylinder 602 facilitates the lifting and lowering of the cross column 603 and its surface sprocket 604. Since the two ends of the chain 605 are respectively connected to the mounting frame 3 and the fixing plate 601, it is convenient to drive the mounting frame 3 to lift and lower, thereby facilitating the lifting or lowering of the calender rolls. The movable plate 2 slides on the inner walls on both sides of the frame 1, improving the lifting and lowering stability of the mounting frame 3, avoiding the negative impact of manual roll changing, and improving the efficiency and safety of calender roll changing.

[0029] Please refer to the specific details. Figure 2 As shown, the hydraulic cylinder 602 is equipped with an adjusting handle 7 and an adjusting foot pedal 8.

[0031] Please refer to the specific details. Figure 3 As shown, each arc-shaped bracket 5 has a protective pad 9 installed on its outer wall.

[0032] In this embodiment, the protective pad 9 provides a certain buffering and anti-slip effect, improving the stability of the calender roll lifting, while also facilitating the protection of the arc-shaped bracket 5 and improving its safety in use.

[0033] Please refer to the specific details. Figure 2 As shown, a protective plate 10 is fixedly installed on the outer wall of the frame 1.

[0034] In this embodiment, the protective plate 10 facilitates the protection of the cross post 603 and the sprocket 604, thereby improving their safety during use.

[0035] Please refer to the specific details. Figure 1 As shown, the frame 1 is equipped with two movable wheels 11 and two omnidirectional wheels 12, and handrails 13 are fixedly connected to the outer walls on both sides of the frame 1.

[0036] In this embodiment, the movable wheels 11 and the universal wheels 12 facilitate the position transfer of the frame 1 and the roller changing work, and the handrail 13 facilitates the movement of the frame 1.

[0037] Please refer to the specific details. Figure 1 As shown, a counterweight box 14 is fixedly installed on the top of the frame 1.

[0038] In this embodiment, the counterweight box 14 facilitates the placement of the counterweight blocks and improves the stability of the frame 1.

[0039] Working principle: When in use, push the handle 13, and with the help of the moving wheels 11 and the universal wheels 12, push the frame 1 to the appropriate position of the calender. Operate the hydraulic cylinder 602 by adjusting the handle 7 or the foot pedal 8 to drive the cross column 603 and its surface sprocket 604 to rise. Since the two ends of the chain 605 are connected to the mounting frame 3 and the fixed plate 601 respectively, the mounting frame 3 is driven to rise, and the two arc-shaped brackets 5 are driven to rise to the appropriate position below the calender roll. Place the replaced roll on the arc-shaped bracket 5. The movable plate 2 improves the stability of the lifting and lowering of the mounting frame 3. Operate the hydraulic cylinder 602 by adjusting the handle 7 or the foot pedal 8 to drive the mounting frame 3, the arc-shaped brackets 5 and the roll to fall. Remove the old roll and place the new roll on the arc-shaped bracket 5. Repeat the lifting action to complete the roll replacement.
