[0028] like Figure 1-Figure 6 As shown, a preferred embodiment of the utility model; a cardboard dust removal device includes a frame 100, a conveying component 200 and a dust removal component 300, wherein the conveying component 200 and the dust removal component 300 are both arranged on the upper side of the frame 100, wherein the dust removal component 300 is located on the upper side of the conveying component 200, so that the dust removal end 301 in the dust removal component 300 abuts against the surface of the cardboard conveyed on the conveying component 200; the dust removal device also includes a cleaning component 400, and the cleaning component 400 is used to clean the dust removal component 300 after the cardboard is dusted, that is, the cleaning component 400 is used to clean and dust the cleaning end 302 of the dust removal component 300, and in the utility model, the cardboard dust removal operation and the cleaning operation of the dust removal component 300 can be performed simultaneously, so that the dust removal operation is more efficient.

[0029] Specifically, the cleaning component 400 includes a water tank 401 and a cleaning roller 402 disposed in the water tank 401. The water tank 400 is fixed above the frame 100 through a support rod 403. The water tank 401 is filled with clean water, and the water level is close to the top of the driven roller 303 of the cleaning end. The cleaning end of the dust removal component 300 is inserted into the water tank 400 and is in parallel contact with the cleaning roller 402, that is, the driven roller 303 of the cleaning end is parallel to the cleaning roller 402, so that the dust removal belt 301 wound around the driven roller 303 at the cleaning end is immersed in clean water, and it is ensured that when the cleaning roller 402 rotates, the cleaning roller 402 can clean the cleaning end of the dust removal component. And the cleaning roller 402 is driven by a third driving motor 403 disposed outside the water tank.

[0030] Specifically, the conveying assembly 200 includes a conveying belt driving roller 201 and a conveying belt driven roller 202 arranged on the frame 100, and a conveying belt 203 is sleeved on the conveying belt driving roller 201 and the conveying belt driven roller 202, wherein the conveying belt driving roller 201 is driven by a first driving motor 204 arranged on the side of the frame 100, and the conveying belt 203 rotates clockwise (here, the clockwise rotation is based on Figure 4 shown).

[0031] After the dust removal component 300 performs the dust removal operation, the dust removal belt 301 is contaminated by dust and other debris on the cardboard. In order to facilitate dust removal and cleaning at the same time, the dust removal component is specifically as follows: it includes a driving roller 302, a driven roller 303, and a dust removal belt 301 sleeved on the driving roller 302 and the driven roller 303. The dust removal belt 301 is changed by the first changing roller 304 and the second changing roller 305 to form an ascending section 301a and a descending section 301b. The lower end of the descending section 301b is the dust removal end 300a, and the lower end of the ascending section 301a is the cleaning end 300b. Specifically, the driving roller 302 and the first changing roller 304 are rotatably arranged on the vertical plate 101 on the upper side of the frame 100, and the driving roller 302 is driven by the second driving motor 306 arranged on the outer side of the vertical plate 101, wherein the driven roller 303 and the second changing roller 305 are rotatably arranged on the side wall of the water tank 401. The dust removal belt 301 between the driving roller 302 and the driven roller 303 is made to protrude upward.

[0032] In order to provide support for the conveyor belt 203 so that the cardboard on the dust removal belt 301 can maintain contact with the dust removal end 300a in the dust removal assembly 300, a support plate 205 is provided on the lower side of the conveyor belt 203 where the cardboard is directly supported, so as to support the upper part of the conveyor belt 203 between the conveyor belt driving roller 201 and the conveyor belt driven roller 202.

[0033] In order to prevent water from dripping on the dust removal belt 301 of the rising section that has not been squeezed out, the length of the water trough 401 is greater than or equal to the downward projection length of the dust removal belt 301 of the rising section 301a, so that the dust removal belt 301 of the rising section 301a can be completely above the water trough 401, thereby ensuring that the water on the dust removal belt 301 can completely drip into the water trough 401.

[0034] In order to remove the moisture on the dust removal belt 301 after cleaning as much as possible and avoid excessive moisture in the dust removal belt 301 during dust removal operation, which causes excessive humidity in the paperboard, the dust removal assembly 300 also includes a water squeezing structure. Specifically, the water squeezing structure is two water squeezing rollers 307, which are arranged in parallel, and the gap between the two water squeezing rollers 307 is smaller than the thickness of the dust removal belt 301. Here, the gap between the two water squeezing rollers 307 is large enough to ensure that the moisture content on the dust removal belt 301 is less than 5% after being squeezed by the two water squeezing rollers 307.

[0035] It should be noted that the two squeezing rollers 301 roll and clamp the upper part of the dust removal belt 301 in the upper lifting section 301a to squeeze out the water in the dust removal belt 301 that has been cleaned.

[0036] Embodiment 2

[0037] On the basis of the first embodiment, in order to ensure that the cardboard is dry after the dust removal belt 301 is dusted, and to avoid the damp dust removal belt 301 causing the cardboard to be too wet, which makes it difficult to discharge the moisture inside the cardboard after lamination, the dust removal device on the basis of the first embodiment also includes a dehumidification component, which is used to dry and dehumidify the cardboard after the dust removal belt dust removal operation. Specifically, the dehumidification component is a hot air pipe 500 arranged at the bottom of the water tank, and a plurality of hot air outlet holes are opened on the side of the hot air pipe 500 opposite to the conveying component, that is, to ensure that the hot air blown out by the hot air pipe 500 is directly blown onto the cardboard on the conveying belt 203. There are many ways to realize the source of hot air placed in the hot air pipe 500, for example, hot air can be provided by an external heat source, or a hot air blower can be set in the present embodiment itself to realize self-heating. Of course, in order to increase the dehumidification effect, the number of air pipes can be set according to actual conditions.
