Description

Technical Field

[0001] The invention relates to calendering equipment, belonging to the technical field of raw material processing equipment. Background Art

[0002] Calendering equipment plays an important role in industries such as rubber, plastics and non-ferrous metal processing. It is generally composed of two or more rollers. During use, the calendering equipment needs to process the material in a reciprocating cycle. During continuous use of the equipment, the rollers will become skewed, resulting in different gaps between the two sections of the two rollers, which will lead to quality problems in the pressed products. The current calendering equipment has a limited angle adjustment range, which cannot compensate and correct the equipment well, nor can it actively adjust the distance between the two ends of the rollers to extrude products with gradual thickness changes. In order to avoid impurities in the calendered products during the production and processing process, the rollers often need to be cleaned before use. When cleaning the attachments on the surface of the upper roller, it often affects the lower roller, and the attachments cannot be well guided out, making it inconvenient to clean them simultaneously. In order to ensure the adjustment of the gap, most of the current calendering equipment uses a pulley combined with a pressure wheel or a multi-motor driven roller for transmission. The two methods have problems such as low torque and high cost. Summary of the Invention

The universal joint 16 is connected to the rotating shaft of the upper roller 37 through an auxiliary support seat 17;

[0026] When calendering work is required, the main motor 12 is started, and the main motor 12 will drive the lower gear set 13 and the upper gear set 14 to rotate synchronously through the main shaft 33. The lower gear set 13 will drive the lower roller 24 to rotate through the rotating shaft, and the upper gear set 14 will drive the upper roller 37 to rotate through the adjusting mechanism. The direction of rotation can be changed by changing the setting direction of the lower gear set 13 and the upper gear set 14.

[0027] The upper gear assembly seat 15 is connected to an adjustment mechanism capable of adjusting the upper roller 37 up and down and adjusting the inclination;

[0028] The adjusting mechanism includes a movable plate 28 fixedly connected to the upper gear assembly seat 15, the auxiliary support seat 17 passes through the movable plate 28 and is fixedly connected to a connecting rod 27, a slide groove is provided at the end of the connecting rod 27, and an adjusting block 22 and a screw rod 23 threadedly connected to the adjusting block 22 are slidably provided in the slide groove, and the screw rod 23 is connected to the adjusting motor 20; the adjusting motor 20 is fixedly set on the mounting seat located on the movable plate 28, and the hydraulic cylinder 18 is mounted on the hydraulic cylinder mounting seat 19, and the hydraulic cylinder mounting seat 19 is fixedly connected to the cross bar between the two support seats 10.

[0029] A push plate 21 is fixedly provided at the center of the movable plate 28, and the upper end surface of the push plate 21 is fixedly connected to the protruding end of the hydraulic cylinder 18. The movable plate 28 is vertically slidably provided in the slideway provided in the support seat 10, and a guide rod 26 is fixedly provided in the slideway.

When it is necessary to remove the attached crops on the lower roller 24, the vertical position of the collection plate 35 can be adjusted so that the scraper 36 is close to the outer surface of the roller 24, leaving a gap between the scraper 36 and the horizontal section of the collection plate 35. The device is then started to rotate the roller 24. The rotation of the roller 24 causes the attached crops to come into contact with the scraper 36 and be scraped off. The attached crops are then sent out through the reserved gap.
