Description

Technical Field

[0001] The utility model relates to the technical field of cardboard processing, in particular to a cardboard surface cleaning device. Background Art

[0002] Corrugated cardboard has good compression and shock resistance. At the same time, it is light in weight and has good economic performance. During the production process of corrugated cardboard, a printing line group is required to print the corrugated cardboard.

[0003] In order to reduce the interference of debris on printing, the printed surface of the cardboard needs to be cleaned by a cleaning device. The existing cleaning method is to use a purge gas to clean the surface of the cardboard to separate the dust from the cardboard surface. However, the purge gas can only clean dust with poor adhesion and cannot clean adhesives with strong adhesion on the cardboard surface, thereby reducing the cleaning effect of the cardboard. Utility Model Content

[0004] The utility model aims to solve the defect in the prior art that adhesives with relatively high adhesive strength on the cardboard surface cannot be cleaned, thereby reducing the cleaning effect of the cardboard, and proposes a cardboard surface cleaning device.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A cardboard surface cleaning device is designed, comprising a base frame, two parallel limiting rollers rotatably connected to the base frame, and a cleaning mechanism for cleaning the cardboard connected to the base frame;

[0007] The cleaning mechanism includes a motor, which is fixedly connected to the base frame. The output end of the motor is fixedly connected to a rotating roller, a fixed sleeve is sleeved on the rotating roller, and a plurality of elastic convex strips are connected to the fixed sleeve at equal intervals along the axis direction.

[0008] The base frame is connected to an anti-accumulation mechanism for preventing dust from accumulating on the elastic convex strips, the anti-accumulation mechanism comprising a connecting rod, one end of the connecting rod is fixedly connected to the base frame, the other end of the connecting rod is fixedly connected to an arc-shaped plate, the concave surface of the arc-shaped plate is fixedly connected to a friction pad, the friction pad is in contact with the upper end of the elastic convex strip, and the bottom end of the arc-shaped plate is fixedly connected to a collection rack;

[0009] The base frame is connected to a purge mechanism for preventing dust generated by the friction between the friction pad and the elastic ridges from falling onto the cardboard. The purge mechanism includes a fixed frame, which is fixedly connected to the base frame. The fixed frame is located between the arc plate and the limiting roller. Several fans are connected to the fixed frame at equal intervals along the length direction.

[0010] Preferably, the elastic convex strips are sponge strips.

[0011] Preferably, a support plate is fixedly connected to the base frame, and the support plate is located directly below the rotating roller.

[0012] Preferably, the friction pad is a sandpaper pad.

[0013] The paperboard surface cleaning device proposed in the utility model has the following beneficial effects:

[0014] After the motor is started, it drives the rotating roller to rotate. The rotating direction of the rotating roller is opposite to the traveling direction of the cardboard. The rotating roller drives the fixed sleeve to rotate. The fixed sleeve drives a number of elastic convex strips to rotate. During the rotation process, the several elastic convex strips respectively contact the upper surface of the cardboard, frictionally removing dust from the upper surface of the cardboard, which can effectively remove the adhesive on the surface of the cardboard, thereby improving the cleaning effect of the cardboard.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-4 , a cardboard surface cleaning device, comprising a base frame 1, wherein:

[0022] Two parallel limiting rollers 2 are rotatably connected to the base frame 1, and a cleaning mechanism 3 for cleaning the cardboard is connected to the base frame 1;

[0023] The cleaning mechanism 3 includes a motor 31, which is fixedly connected to the base frame 1. The output end of the motor 31 is fixedly connected to a rotating roller 32, and a fixed sleeve 33 is sleeved on the rotating roller 32. The fixed sleeve 33 is connected to a plurality of elastic ridges 34 at equal intervals along the axis direction. The elastic ridges 34 are sponge strips. A support plate 4 is fixedly connected to the base frame 1 and is located directly below the rotating roller 32.

[0024] The bottom frame 1 is connected to an anti-accumulation mechanism 6 for preventing dust from accumulating on the elastic ridges 34. The anti-accumulation mechanism 6 includes a connecting rod 61, one end of the connecting rod 61 is fixedly connected to the bottom frame 1, and the other end of the connecting rod 61 is fixedly connected to an arc plate 62. The concave surface of the arc plate 62 is fixedly connected to a friction pad 63, and the friction pad 63 contacts the upper end of the elastic ridge 34. The friction pad 63 is a sandpaper pad. The bottom end of the arc plate 62 is fixedly connected to a collecting rack 64. The connecting rod 61 fixes the arc plate 62, and the arc plate 62 fixes the friction pad 63. After the elastic ridge 34 rotates, it contacts the friction pad 63. The friction pad 63 rubs the elastic ridge 34, so that the dust is separated from the elastic ridge 34. Part of the separated dust falls into the collecting rack 64, and the friction pad 63 rubs the elastic ridge 34 to prevent dust from accumulating on the elastic ridge 34.

[0025] The base frame 1 is connected to a purge mechanism 5 for preventing dust generated by the friction between the friction pad 63 and the elastic ridge 34 from falling on the cardboard. The purge mechanism 5 includes a fixed frame 51, which is fixedly connected to the base frame 1. The fixed frame 51 is located between the arc plate 62 and the limiting roller 2. A number of fans 52 are connected to the fixed frame 51 at equal intervals along the length direction. When the fan 52 is powered on and started, it generates purge gas. The purge gas blows the dust gas flowing in the direction of the limiting roller 2 to prevent dust from falling on the cleaned cardboard, thereby improving the cleaning effect of the cardboard.

[0026] Working process: the cardboard passes through the gap between two parallel limiting rollers 2. The two limiting rollers 2 are distributed and contact the upper and lower surfaces of the cardboard to squeeze and limit the cardboard. At the same time, the upper end of the support plate 4 contacts the lower surface of the cardboard, and the elastic ridges 34 contact the upper surface of the cardboard. After the motor 31 is started, it drives the rotating roller 32 to rotate. The rotation direction of the rotating roller 32 is opposite to the direction of travel of the cardboard. The rotating roller 32 drives the fixed sleeve to rotate, and the fixed sleeve drives several elastic ridges 34 to rotate. During the rotation process, several elastic ridges 34 respectively contact the upper surface of the cardboard, and friction dust removal is performed on the upper surface of the cardboard, which can effectively remove the adhesive on the surface of the cardboard. At the same time, after the elastic ridges 34 rotate, they drive the gas to flow. The flowing gas drives the dust generated by the contact between the elastic ridges 34 and the cardboard to move, so that the dust is separated from the cardboard. The friction between the elastic ridges 34 and the upper surface of the cardboard effectively removes the adhesive, thereby improving the cleaning effect of the cardboard.

[0027] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
