[0022] See also Figure 1-4 A calender anti-sticking device comprises: a frame 1, a calender roller 101 is arranged on the surface of the frame 1; a scraper mechanism 2, the scraper mechanism 2 is arranged on the surface of the frame 1 and located on one side of the calender roller 101, and the scraper mechanism 2 is used to clean the rubber adhered to the surface of the calender roller 101; an auxiliary mechanism 3, the auxiliary mechanism 3 is arranged on the surface of the scraper mechanism 2, and the auxiliary mechanism 3 is used to heat the surface of the calender roller 101 after scraping; wherein the scraper mechanism 2 comprises a connecting shell 201 arranged on one side of the calender roller 101, and the interior of the connecting shell 201 is fixedly connected with uniformly distributed mounting shells 203, and the connecting shell 201 is fixedly connected with the mounting shells 203. A connecting shell 201 is provided, and a collecting chamber is formed between two adjacent mounting shells 203. A scraper block 202 is fixedly connected to the surface of the connecting shell 201. The other side of the scraper block 202 contacts the surface of the calendering roller 101. A feed trough connected to the connecting shell 201 is provided on the surface of the scraper block 202. A discharge pipe 210 connected to the collecting chamber and symmetrically distributed with the feed trough is provided on the surface of the mounting shell 203. A connecting block 208 is provided inside the collecting chamber. A rotating shaft 205 is rotatably connected between the connecting block 208 and the inner wall of the collecting chamber. Evenly distributed push plates 204 are fixedly connected to the surface of the rotating shaft 205.

[0023] During the rotation of the calender roller 101, it can contact the scraper block 202, and under the action of the scraper block 202, the rubber adhering to the surface of the calender roller 101 can be scraped off and dropped into the inside of the feed trough, and under the action of gravity, the rubber can gradually slide into the inside of the collection chamber, and the push plate 204 can be driven to rotate by rotating the rotating shaft 205, so that the push plate 204 can drive the rubber dropped into the collection chamber to be discharged from the inside of the collection chamber through the discharge pipe 210, so as to achieve the effect of timely discharging the cleaned rubber;

[0024] See also Figure 1-4 The inner wall of the installation shell 203 is provided with a fan 206, and one side of the installation shell 203 is provided with filter holes 207 that are evenly distributed in a semicircular shape and communicated with the collection chamber. The surface of the connection shell 201 is fixedly connected with a connection box 216 located below the installation shell 203, and the lower surface of the installation shell 203 is provided with ventilation slots 211 that are evenly distributed and communicated with the connection box 216;

[0025] One end of the rotating shaft 205 passes through the adjacent connecting block 208 and is fixedly connected to a transmission mechanism 209, and the other end of the transmission mechanism 209 passes through the connecting block 208 and the connecting shell 201 in sequence and extends to the outside of the connecting shell 201;

[0026] The inner wall of the connection box 216 is fixedly connected with a partition 212, and the surface of the partition 212 is provided with evenly distributed guide grooves 213. The inner wall of the connection box 216 is rotatably connected with a rotating rod 214 located below the partition 212, and the surface of the rotating rod 214 is fixedly connected with annularly distributed driving blades 215, and the other end of the rotating rod 214 passes through the connection box 216 and is fixedly connected to the other end of the transmission mechanism 209;

[0027] By starting the fan 206, the external airflow can be guided to the inside of the installation shell 203 through the feed slot, the collection chamber and the filter hole 207 under the action of the fan 206, and introduced into the inside of the connection box 216 through the ventilation slot 211. The airflow entering the connection box 216 can be guided by the guide slot 213 to drive the blade 215 to rotate, thereby driving the rotating rod 214 to rotate. In this process, the rotation shaft 205 can be driven to rotate through the transmission mechanism 209, thereby driving the push plate 204 to push the rubber dropped into the collection chamber to be discharged through the discharge pipe 210. In addition, since the filter hole 207 is not provided in the area corresponding to the surface of the installation shell 203 of the discharge pipe 210, the rubber between the two push plates 204 will not be disturbed by the airflow when it reaches the discharge pipe 210, so as to facilitate the discharge of the rubber. The transmission mechanism 209 is a relatively mature component in the existing technology application, which is composed of two transmission wheels and a transmission belt. By driving one of the transmission wheels to rotate, the other transmission wheel can be driven to rotate synchronously under the action of the transmission belt.

[0028] When the airflow enters the feed trough, it can fully contact the surface of the calender roller 101, thereby cooling the rubber adhered to the surface of the calender roller 101, so that it can harden and shrink so that the scraper 202 can scrape it off. In the process of airflow movement, the scraped rubber can be quickly carried into the collection chamber, thereby accelerating the discharge of the scraped rubber and avoiding rubber accumulation that affects the subsequent cleaning effect of the adhered rubber.

[0029] See also Figure 1-4 The auxiliary mechanism 3 includes a mounting tube 301 fixedly connected to the surface of the connection box 216, one end of the mounting tube 301 is connected to the adjacent connection box 216, the horizontal height of the mounting tube 301 is lower than the horizontal height of the partition 212, a heater 303 is arranged inside the mounting tube 301, and the surface of the mounting tube 301 is provided with uniformly distributed spray holes 302, and the spray holes 302 can guide the airflow to spray toward the calender roller 101;

[0030] The airflow passing through the partition 212 is introduced into the interior of the mounting tube 301, and is heated by the heater 303, and the heated airflow is sprayed toward the surface of the cleaned calendering roller 101 through the spray hole 302, so as to avoid the airflow causing the surface of the calendering roller 101 to cool down during the cleaning process and affect the subsequent use effect.

[0031] Working principle: By starting the fan 206, the external airflow is guided to the inside of the mounting shell 203 through the feed trough, the collecting chamber and the filter hole 207. In this process, the airflow can fully contact the surface of the calender roller 101, and then cool the rubber adhering to the surface of the calender roller 101, so that it can harden and shrink so that the scraper 202 can scrape it off. In the process of airflow movement, the scraped rubber can be quickly introduced into the inside of the collecting chamber to speed up the discharge of the scraped rubber, avoid rubber accumulation affecting the subsequent cleaning effect of the adhering rubber, and under the mutual cooperation of the ventilation slot 211 and the guide slot 213, the airflow can drive the blade 215 to rotate. The rubber that has fallen into the collecting chamber is discharged through the discharge pipe 210 because the filter hole 207 is not provided in the area on the surface of the mounting shell 203 corresponding to the discharge pipe 210, so that the rubber between the two push plates 204 will not be disturbed by the airflow when it reaches the discharge pipe 210, so as to facilitate the discharge of the rubber. Under the action of the auxiliary mechanism 3, the airflow is heated and sprayed onto the surface of the calendering roller 101, so as to avoid the cooling of the surface of the calendering roller 101 caused by the airflow during the cleaning process, which may affect the subsequent use effect.

[0032] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit thereof, and that the scope of the present invention is defined by the appended claims and their equivalents.
