On a calendering production line, the open mill is located before the calender and after the mixer. Its function is to mix and plasticize the evenly mixed raw materials, providing a uniformly mixed and plasticized molten material for the calender to form the plastic products.

[0003] After searching, a patent with application publication number CN208601746U discloses a rubber mixing mill roller with anti-sticking function, which relates to the technical field of mixing mill rollers and includes a roller fixing seat, the upper surface of the roller fixing seat is fixedly connected to a roller baffle, the interior of the roller baffle is movably connected to the roller, a cooling pipe is inserted into the interior of the roller, one side of the roller baffle is fixedly connected to an oil storage tank, the upper surface of the oil storage tank is fixedly connected to an oil supply pipe, and the upper surface of the roller fixing seat is fixedly connected to a first sleeve on the side close to the roller baffle.

[0004] The rubber mixing mill roller reduces rubber adhesion by cooling, and adopts scraping with a scraper, brushing off residual rubber, and oiling the roller to reduce roller adhesion and improve the roller's anti-adhesion effect. However, the fixed scraper only relies on the periodic rotation of the roller for non-targeted scraping and cannot perform repeated scraping actions on the adhesion position, which affects the effect and efficiency of cleaning the roller outer wall; and the scraper continuously scraping the non-adhesive area of ​​the roller may damage the roller surface coating. Utility Model Content

The knife seat is slidably connected in the slide groove. A clearance groove for the blade to pass through is opened on the side of the fixed seat close to the roller body.

[0010] Preferably, the mounting frame includes a swing arm, a mounting portion and a pocket portion, the mounting portion is welded to the bottom end of the swing arm, and the pocket portion is fixed to the bottom end of the mounting portion.

[0011] Preferably, the rotating structure includes a rotating motor, a rotating shaft is fixed to the output end of the rotating motor, the rotating shaft is rotatably connected in the extension frame, and the top end of the swing arm is fixed to the outer wall of the rotating shaft.

[0025] 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.

[0026] See also Figure 1-4 The utility model provides a technical solution: an anti-sticking open mill roller for rubber processing, comprising a roller body 1, a bracket 2 for supporting the roller body 1 is installed on the outside of the roller body 1, and an extension frame 3 is fixed to both ends of the bracket 2 by screws. A scraping structure 4 for scraping glue specifically on the outer wall of the roller body 1 is provided on one side of the roller body 1;

[0027] The scraping structure 4 includes a mounting frame 401 that can synchronously collect the scraped waste glue, and a distance sensor 402 for sensing the distance to the outer wall of the roller body 1 and a scraper 403 for scraping glue on the outer wall of the roller body 1 are installed in the mounting frame 401. An electric control box 8 electrically connected to the distance sensor 402 is fixed above the mounting frame 401, and a driving structure 5 for controlling the repeated arc movement of the scraper 403 is provided at the bottom end of the mounting frame 401, and a rotating structure 6 for adjusting the position of the mounting frame 401 is provided at the top of the extension frame 3.

[0028] A number of distance sensors 402 are arranged in a horizontal array to monitor the distance between the roller surfaces in real time, locating areas of rubber adhesion. The main control panel within the electrical control box 8 directs the scraper 403 to clean only those areas of concern. Compared to conventional full-circle scraping, this improves cleaning efficiency and avoids ineffective friction between the scraper 403 and unadhered areas, extending the life of the roller surface coating.

[0029] The driving structure 5 includes a driving motor 501, a fixed seat 502 and a knife seat 503. A blade 504 is fixed in the knife seat 503. The fixed seat 502 is fixedly connected to the mounting frame 401 by screws. The driving motor 501 is fixed in the fixed seat 502. A driving gear 505 is fixed to the output end of the driving motor 501. The outer wall of the knife seat 503 is provided with teeth 506. The driving gear 505 is engaged with the teeth 506. A sliding structure 7 for the knife seat 503 to slide is provided in the fixed seat 502.

[0030] After the driving motor 501 is started, the driving gear 505 rotates, and drives the knife holder 503 to move in an arc in the slide groove 701 through the teeth 506, so that the knife holder 503 drives the scraper 403 to move in an arc, repeatedly scraping glue on the outer wall of the roller body 1.

[0031] The sliding structure 7 includes a slide groove 701, which is opened in the inner cavity of the fixed seat 502. The slide groove 701 and the knife seat 503 are both arranged in an arc shape. The knife seat 503 is slidably connected in the slide groove 701. The fixed seat 502 is provided with a clearance groove 702 on the side close to the roller body 1 for the blade 504 to pass through.

[0032] The mounting frame 401 includes a swing arm 4011 , a mounting portion 4012 and a pocket portion 4013 . The mounting portion 4012 is welded to the bottom end of the swing arm 4011 , and the pocket portion 4013 is fixed to the bottom end of the mounting portion 4012 .

[0033] The bottom of the pocket cavity 10 is provided with a diversion slope, so that the scraped rubber material enters the pocket cavity 10, reducing the frequency of manual cleaning.

[0034] The rotating structure 6 includes a rotating motor 601 , the output end of the rotating motor 601 is fixed with a rotating shaft 602 , the rotating shaft 602 is rotatably connected in the extension frame 3 , and the top end of the swing arm 4011 is fixed to the outer wall of the rotating shaft 602 .

[0035] After the motor 601 is driven, the rotating shaft 602 rotates, driving the swing arm 4011 to swing, so that the scraper 403 is away from the roller body 1 when not working, and is close to the roller body 1 when working.

[0036] The distance sensors 402 are provided in multiple groups, and the multiple groups of distance sensors 402 are arranged in an equidistant linear manner.

[0037] The pocket portion 4013 is arranged in an arc shape, and side plates 9 are welded to both ends of the pocket portion 4013. The side plates 9 and the inner wall of the pocket portion 4013 form a pocket cavity 10.

[0038] During use, the motor 601 is driven, rotating the shaft 602 and causing the swing arm 4011 to swing, bringing the scraper 403 closer to the roller body 1. The distance sensor 402 uses an infrared distance sensor, which detects the distance of the obstacle by using the principle that the intensity of the infrared signal's reflection varies depending on the distance from the obstacle. When rubber adhesion is detected on the outer wall of the roller body 1, the scraper 403 controls the swing arm 4011 by rotating the motor 601, so that it adheres to the outer wall of the roller body 1. The main control board in the electronic control box 8 activates the drive motor 501, which drives the gear 505 to rotate. The teeth 506 drive the blade holder 503 to move in an arc within the slide 701, achieving arc movement of the blade holder 503 and repeatedly scraping the rubber from the outer wall of the roller body 1. Compared with the traditional fixed blade holder scraping method, this method can perform more targeted scraping, improve the scraping efficiency, and at the same time improve the cleanliness of the outer wall of the roller, and avoid the ineffective friction of the scraper 403 on the non-adherent area, which can extend the life of the roller surface coating.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
