[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] Example: Reference Figure 1-5 The three-roller calendering device for PVC sheets shown in the figure includes a frame 1, three groups of symmetrical adjustment seats 2 are provided on the frame 1, and each group of adjustment seats 2 is provided with a mounting seat 3 (a pair of upper and lower mounting seats 3 are slidably connected to the adjustment seats 2), a lifter is provided on the frame 1, and the lifter is symmetrically arranged up and down, and the upper mounting seat 3 and the lower mounting seat 3 of the holes respectively move on the adjustment seat 2, and the mounting seat 3 is a U-shaped structure when not in use, and the slidingly connected fixing mechanism inside it can quickly use the limiting calendering roller, and an auxiliary positioning mechanism is also provided on the mounting seat 3. After the fixing mechanism is used, the auxiliary positioning mechanism is connected to the fixing mechanism for secondary fixation.
[0022] The fixing mechanism: The mounting seat 3 includes a No. 1 mounting seat 31 and a No. 2 mounting seat 32, both of which are AB parts and are fixed by bolts. The opposite surfaces of the No. 1 mounting seat 31 and the No. 2 mounting seat 32 are provided with movable grooves 33 for the sliding of the locking member 4. The movable groove 33 is a C-shaped structure, and the locking member 4 is a J-shaped structure. A slide groove 34 is provided on the inner wall of the movable groove 33, and the slide groove 34 is arranged concentrically with the movable groove 33. An outer ring tooth 5 is provided on the outer wall of the locking member 4, and the outer ring tooth 5 is slidably connected in the slide groove 34. The No. 1 mounting seat 31 and the No. 2 mounting seat 32 have the same structure and are symmetrically arranged; an adjusting groove 35 tangent to the slide groove 34 is provided at the bottom of the mounting seat 3 (the adjusting groove 35 and the slide groove 34 are connected), and an adjusting rod 6 is rotatably connected in the adjusting groove 35. The adjusting rod 6 is a worm, and the outer ring tooth 5 is a worm gear tooth. Self-locking is achieved through the structural design of the worm gear.
[0023] Auxiliary positioning mechanism: A through hole 36 is provided on the mounting seat 3, and the through holes 36 are symmetrically arranged. They are provided on both the No. 1 mounting seat 31 and the No. 2 mounting seat 32, and a positioning hole 41 is provided on the locking member 4, which is concentric with the through hole 36. The sizes of the positioning hole 41 and the through hole 36 match, and a pin is slidably connected in the through hole 36. After the locking member 4 rotates 180 degrees, the inner end of the pin is threaded into the positioning hole 41 to achieve secondary fixation.
[0024] The working principle of this utility model is as follows: by installing the mounting seat 3 onto the adjusting seat 2, and then inserting the prepared calendering roller into the mounting seat 3, use a tool to rotate the adjusting rod 6 at the bottom of the mounting seat 3, and the adjusting rod 6 rotates in the adjusting groove 35, driving the outer ring gear 5 to rotate around the center of the circle on the mounting seat 3 (the outer ring gear 5 rotates in the slide groove 34), and the rotating outer ring gear 5 drives the locking piece 4 to rotate in the movable groove 33. During the rotation process, the bottom end face of the locking piece 4 rotates from the lower movable groove (below the center of the circle) into the upper movable groove (above the center of the circle), so that the positioning hole 41 and the through hole 36 are positioned relative to each other, and the pin passes through the through hole 36 and is inserted into the positioning hole 41. After locking is completed, the calendering roller is fixed. Then, according to processing needs, the lifter on the frame 1 is controlled to control the mounting seat 3 to slide on the adjusting seat 2.
