Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of aluminium slag cleaning, and particularly relates to a device for removing aluminium slag from a cold drum. BACKGROUND

[0002] The coated cooling drum is composed of an outer cylinder, an inner cylinder and a middle shaft. The embedded cooling flow channel maintains the low temperature state of the surface of the coated drum by circulating cooling liquid. During the coating process, the coated drum not only provides stable support, but also removes the radiant heat of the coated material through efficient heat exchange, effectively preventing the deformation of the thin film due to heat, and ensuring the coating quality and uniformity. The coated cooling drum is widely used in high-barrier food packaging, gold and silver wire manufacturing and other fields. Its advantages lie in accurate control of the coating temperature, improved production efficiency, and reduced energy consumption and production cost.

[0003] During the coating process, if the heating step of the evaporation boat is completed and the aluminum liquid cannot spread uniformly, it usually means that the molten pool range of the evaporation boat is relatively small. In this case, the aluminum liquid is easy to accumulate in the evaporation boat, forming an aluminum accumulation phenomenon. As the temperature of the accumulated aluminum liquid rises, it will start to boil, and the gas bubbles generated during the boiling process may cause the aluminum liquid to splash. The splashing of the aluminum liquid is a serious problem because it may cause the base film to be burned through. Once the aluminum liquid penetrates the base film, it will directly contact the surface of the coated cold drum and cool and solidify there. However, the aluminum slag after cooling and solidification is not taken away with the movement of the base film, but remains on the surface of the coated cold drum. When the coated cold drum rotates one circle, these aluminum slags will press out a concave-convex point on the film surface. Finally, when the film roll is wound, these periodically appearing concave-convex points will leave obvious marks on the film roll, affecting the quality and appearance of the film roll. Therefore, a device for removing aluminum slag from a cold drum is proposed. SUMMARY

[0004] The utility model aims at providing a device for removing aluminum slag from a cold drum to solve the problem that aluminum slag leaves marks on the film surface in the prior art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a device for removing aluminum slag from a cold drum, comprising a coated cold drum, a positioning base is arranged on the upper side of the coated cold drum, an installation support foot is fixedly installed at the bottom of the positioning base, a cleaning mechanism is arranged on the installation support foot, the cleaning mechanism comprises an installation shaft rotatably installed on the installation support foot, an L-shaped frame body is fixedly installed on the installation shaft, a positioning knife holder is fixedly installed at one end of the L-shaped frame body, a cleaning scraper and a suction nozzle are fixedly installed on the positioning knife holder, a sticky roller is rotatably installed at the other end of the positioning knife holder, and a driving mechanism is arranged on the L-shaped frame body.

[0006] Preferably, the L-shaped frame body is rotatably provided with a movable shaft, one end of the mounting shaft is fixedly provided with a worm gear, and the side wall of the mounting leg is rotatably provided with a worm.

[0007] Preferably, the L-shaped frame body is rotatably provided with a movable shaft, one end of the mounting shaft is fixedly provided with a worm gear, and the side wall of the mounting leg is rotatably provided with a worm.

[0008] Preferably, the L-shaped frame body is rotatably provided with a movable shaft, one end of the mounting shaft is fixedly provided with a worm gear, and the side wall of the mounting leg is rotatably provided with a worm.

[0009] Preferably, the L-shaped frame body is rotatably provided with a movable shaft, one end of the mounting shaft is fixedly provided with a worm gear, and the side wall of the mounting leg is rotatably provided with a worm.

[0010] Preferably, the L-shaped frame body is rotatably provided with a movable shaft, one end of the mounting shaft is fixedly provided with a worm gear, and the side wall of the mounting leg is rotatably provided with a worm.

[0011] Preferably, the L-shaped frame body is rotatably provided with a movable shaft, one end of the mounting shaft is fixedly provided with a worm gear, and the side wall of the mounting leg is rotatably provided with a worm.

[0012] Compared with the prior art, the utility model has the advantages that:

[0013] 1、 in the application, under the driving of the worm rotation, the worm gear rotates, and then promotes the rotation of the mounting shaft. The rotation of the mounting shaft drives the rotation of the L-shaped frame body, and the rotation of the L-shaped frame body makes the sticky roller adhere to the surface of the coating cold drum. When the sticky roller closely adheres to the surface of the coating cold drum, the double-head motor can be activated, and the clutch at one end thereof is brought into engagement state to realize the driving rotation of the double-head motor to the sticky roller. Subsequently, the rotation of the sticky roller can effectively adsorb the aluminum slag on the surface of the coating cold drum.

[0014] 2, in the application, under the drive of the counter-rotating worm, the L-shaped frame body will also rotate in reverse, thereby prompting the end of the cleaning scraper to contact the surface of the coated cold drum. During the rotation of the coated cold drum, the cleaning scraper will be used to remove the aluminum slag points on the surface. During the removal of the aluminum slag points, the clutch at the other end of the double-head motor is kept in engagement state, so that the double-head motor can drive the fan blade to rotate at high speed in the volute. The high-speed rotating fan blade will suck out the air in the suction nozzle, forming a negative pressure environment, thereby realizing the suction of the removed impurities.

DETAILED DESCRIPTION

[0021] The technical scheme in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model, apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0022] As Figure 1 And Figure 2The utility model provides a kind of technical scheme of the device for removing cold drum aluminum slag, including coating cold drum 1, and coating cold drum 1 side upper portion is equipped with positioning base 3, and positioning base 3 bottom is fixedly installed with mounting leg 2, and mounting leg 2 is equipped with cleaning mechanism 4, and L-shaped frame body 409 is fixedly installed on mounting shaft 404, and L-shaped frame body 409 one end is fixedly installed with positioning tool rest 403, and positioning tool rest 403 is fixedly installed with cleaning scraper 401 and suction nozzle 402, and L-shaped frame body 409 is equipped with driving mechanism 5, and the cooperation schematic diagram of cleaning mechanism 4 and driving mechanism 5, coating cold drum 1 surface can be cleaned quickly.

[0023] As Figure 2 , Figure 3 and Figure 4 The cleaning mechanism 4 includes a mounting shaft 404 rotatably mounted on the mounting leg 2, an L-shaped frame body 409 fixedly installed on the mounting shaft 404, a positioning tool rest 403 fixedly installed on one end of the L-shaped frame body 409, a cleaning scraper 401 and a suction nozzle 402 fixedly installed on the positioning tool rest 403, a sticky roller 405 rotatably mounted on the other end of the positioning tool rest 403, a movable shaft 408 rotatably mounted on the L-shaped frame body 409, a worm gear 407 fixedly installed on one end of the mounting shaft 404, a worm 406 rotatably mounted on the side wall of the mounting leg 2, and the worm gear 407 is meshed with the worm 406, and the L-shaped frame body 409 is provided with a shaft, and the movable shaft 408 is rotatably mounted on the L-shaped frame body 409 through the bearing.

[0024] Specifically, when the operator rotates the worm 406, the worm 406 will mesh with the worm gear 407 through its spiral structure, and then the worm gear 407 will start to rotate. With the rotation of the worm gear 407, it will transmit power to the mounting shaft 404, so that the mounting shaft 404 also starts to rotate. The rotation of the mounting shaft 404 drives the L-shaped frame body 409 connected thereto to rotate around the shaft center. The rotating action of the L-shaped frame body 409 enables the cleaning scraper 401 and the sticky roller 405 to contact the surface of the coating cold drum 1 respectively. Through this contact, the cleaning scraper 401 can scrape off the excess material on the surface of the coating cold drum 1, and the sticky roller 405 can absorb the residual tiny particles, so as to realize the thorough cleaning of the surface of the coating cold drum 1.

[0025] As Figure 2 and Figure 5As shown, the driving mechanism 5 comprises a positioning sleeve 504 fixedly installed on the L-shaped frame body 409, a double-head motor 501 and a volute 506 fixedly installed in the positioning sleeve 504, clutches 502 arranged at both ends of the double-head motor 501, a speed reducer 503 arranged at one end of the double-head motor 501, the double-head motor 501 fixedly installed on the movable shaft 408 at one end, a fan blade 507 fixedly installed on the other end of the double-head motor 501, and an air suction pipeline 505 connected to the volute 506, the double-head motor 501 being installed at one end of the movable shaft 408 through the positioning sleeve 504.

[0026] Specifically, after the sticky roller 405 is attached to the surface of the film-coated cold drum 1, the double-head motor 501 can be started, and the clutch 502 at one end of the double-head motor 501 is controlled to be in the engaged state, so that the power of the double-head motor 501 can be used to drive the sticky roller 405 to rotate. With the rotation of the sticky roller 405, it can effectively adsorb the aluminum slag on the surface of the film-coated cold drum 1, thereby removing the impurities on the surface. At the same time, if the clutch 502 at the other end of the double-head motor 501 is also in the engaged state, the double-head motor 501 will drive the fan blade 507 to rotate at high speed in the volute 506. This high-speed rotation will suck out the air in the suction nozzle 402, thereby forming a negative pressure environment inside the suction nozzle 402. This negative pressure environment can effectively adsorb the removed impurities, ensuring the cleanliness and efficiency of the film-coating process.

[0027] Working principle: when in use, the film-coated cold drum 1 can be controlled to rotate, and after the film-coated cold drum 1 rotates, the worm 406 can be rotated, and after the worm 406 is rotated, it will drive the worm gear 407 to rotate, and after the worm gear 407 is rotated, it will drive the mounting shaft 404 to rotate, and after the mounting shaft 404 is rotated, it will drive the L-shaped frame body 409 to rotate, and after the L-shaped frame body 409 is rotated, it will drive the sticky roller 405 to rotate and attach to the surface of the film-coated cold drum 1, and after the sticky roller 405 is attached to the surface of the film-coated cold drum 1, the double-head motor 501 can be started and the clutch 502 at one end of the double-head motor 501 is controlled to be in the engaged state, so that the double-head motor 501 drives the sticky roller 405 to rotate, and after the sticky roller 405 rotates, it can adsorb the aluminum slag on the surface of the film-coated cold drum 1, and then the worm 406 can be reversely rotated, and after the worm 406 is reversely rotated, it will drive the L-shaped frame body 409 to reversely rotate, so that the distal end of the cleaning scraper 401 abuts against the surface of the film-coated cold drum 1, and in the process of rotating the film-coated cold drum 1, the aluminum slag points on the surface of the film-coated cold drum 1 are scraped off by the cleaning scraper 401, and at this time, the clutch 502 at the other end of the double-head motor 501 can be controlled to be in the engaged state, and when the clutch 502 at the other end of the double-head motor 501 is in the engaged state, the double-head motor 501 will drive the fan blade 507 to rotate at high speed in the volute 506, thereby sucking out the air in the suction nozzle 402, forming a negative pressure in the suction nozzle 402, and adsorbing the removed impurities.
