A plurality of air exhaust holes are evenly formed in the top wall of the dust hood, an air exhaust hood is installed on the top of the dust hood, a plurality of air holes connected with the air exhaust hood are evenly formed in the top wall of the dust hood, and the center of the air exhaust hood is connected with a negative pressure pipe. Dust on the surface of a dust board is raised through the brush cylinder, the dust is sucked into the exhaust hood to be discharged through cooperation with air inlet, airflow in the exhaust hood moves approximately vertically due to the design of the exhaust holes, and therefore the air pressure is kept consistent, and the dust is sucked rapidly. Under traction and clamping of the two ends of the synchronous roller, the dust board can be prevented from wrinkling or sliding forwards when dust is cleaned, and therefore normal operation of film covering work is guaranteed.

Description

Technical Field

[0001] The utility model relates to dust removal equipment, in particular to a gray paperboard film-coated dust removal device. Background Art

[0002] Gray cardboard is a kind of recycled cardboard made from recycled waste paper. It is mainly used for packaging boxes, etc. In order to achieve a good waterproof effect, the surface will be coated.

[0003] During the lamination process, dust often occurs on the surface of the gray cardboard, which causes a lot of bubbles. This affects the aesthetics on the one hand, and the lamination effect on the other. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a gray paperboard coating and dust removal device to solve the technical problems in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the technical solution of the utility model is:

[0006] A gray cardboard coating and dust removal device comprises a rectangular mounting frame, synchronous rollers driven by a synchronous motor are respectively mounted on both sides of the rectangular mounting frame, a dust hood is mounted in the middle, a brush cylinder is horizontally mounted along the length direction of the center of the dust hood, one end of the rotating shaft of the brush cylinder is connected to the driving motor; a plurality of exhaust holes are evenly arranged on the top wall of the dust hood, an exhaust hood is mounted on the top of the dust hood, a plurality of air holes connected to the exhaust hood are evenly arranged on the top wall of the dust hood, and a negative pressure pipe is connected to the center of the exhaust hood.

[0007] Furthermore, the synchronous motor and the driving motor are both fixed to the outer wall of the rectangular mounting frame through brackets.

[0008] Furthermore, the dust hood is symmetrically mounted with hanging brackets, and fixed cross beams are welded between the tops of the hanging brackets, and fixing screw holes are opened on the cross beams.

[0009] Furthermore, the upper side cross-section of the exhaust hood is an isosceles trapezoid.

[0010] The advantages of the utility model are:

[0011] When the gray cardboard passes through the brush cylinder, the dust on the surface is lifted up, and the dust is sucked into the exhaust hood with the air intake, and then enters the dust collector connected to the negative pressure pipe. The design of the exhaust hole makes the airflow in the dust hood close to vertical movement, so as to maintain consistent air pressure and quickly suck the dust in. Under the traction and clamping of the two ends of the synchronous roller, the gray cardboard can be prevented from wrinkling or sliding forward when cleaning the dust, thereby ensuring the normal lamination work.

[0016] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0017] As shown in the figure:

[0018] A gray cardboard coating and dust removal device comprises a rectangular mounting frame 1, synchronous rollers 2 driven by a synchronous motor 21 are respectively mounted on both sides of the rectangular mounting frame 1, a dust hood 3 is mounted in the middle, a brush cylinder 4 is horizontally mounted along the length direction of the center of the dust hood 3, one end of the rotating shaft of the brush cylinder 4 is connected to a driving motor 41; a plurality of exhaust holes 31 are evenly arranged on the top wall of the dust hood 3, an exhaust hood 5 is mounted on the top of the dust hood 3, a plurality of air holes connected to the exhaust hood 5 are evenly arranged on the top wall of the dust hood 3, and a negative pressure pipe 51 is connected to the center of the exhaust hood 5.

[0019] The utility model is installed in front of the conveyor belt inlet of the gray cardboard laminating machine, the brush cylinder 4 is in contact with the conveyor belt, but there is a gap between the dust hood 3 and the gray cardboard on the conveyor belt. Since the gap is not large, the air intake from the gap will be relatively uniform. The synchronous roller 2 is pressed on the gray cardboard, and its linear speed is consistent with the linear speed of the conveyor belt, thereby clamping the gray cardboard.

[0020] When the gray cardboard passes through the brush cylinder 4, the dust on the surface is lifted up, and the dust is sucked into the exhaust hood 5 (the upper side cross-section of the exhaust hood 5 is an isosceles trapezoid, which can make the airflow suction smoother) with the air intake, and then enters the dust collector connected to the negative pressure pipe 51. The design of the exhaust hole 31 makes the airflow in the dust hood 3 close to vertical movement, thereby maintaining consistent air pressure and quickly sucking in dust.

[0021] Since the brush cylinder 4 will generate a propulsive force on the grayboard when working, the design of synchronous rollers 2 is added on both sides. Under the traction and clamping of the two ends of the synchronous rollers 2, the grayboard can be prevented from wrinkling or sliding forward when cleaning the dust, thereby ensuring the normal lamination work.

[0022] In order to reduce the structural complexity as much as possible, the synchronous motor 21 and the driving motor 41 are both fixed to the outer wall of the rectangular installation frame 1 through the bracket 7.

[0023] For easy installation, the hanging brackets 6 can be symmetrically installed on the dust cover 3, and a fixed crossbeam 61 is welded between the tops of the hanging brackets 6, and a fixing screw hole 62 is opened on the crossbeam.

[0024] The above is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
