When the packaging box is subjected to dust removal pretreatment before being folded and formed, the packaging box is firstly fed into the dust removal cavity of the treatment box. In the dust removal cavity, the dust removal brush looses and brushes off stubborn dust which is adsorbed by static electricity, adheres to viscous substances or is hidden in gaps of a complex structure through friction between the dust removal brush and the surface of the packaging box, and preliminary dust removal work is completed. And then, the packaging box enters the drying cavity through a notch in the partition plate.

Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, and more specifically, to a dust removal pretreatment device for the surface of packaging boxes. Background Technology

[0002] Before folding and shaping, packaging boxes require pre-treatment to remove surface dust. Current dust removal processes primarily employ two common methods: blower blowing and brush cleaning. However, both methods have inherent technical limitations. While blower blowing can quickly remove some loose dust, it is often ineffective at removing stubborn dust adhering to the packaging box surface, such as dust attracted by static electricity, adhered to sticky substances, or hidden in the complex crevices of the box's structure. Brush cleaning, while loosening and removing stubborn dust through brush friction, is prone to generating static electricity during operation.

[0003] Static electricity is primarily generated based on the principle of triboelectric charging. However, environmental factors also significantly influence its occurrence. In dry environments with low humidity, the surface charge of objects is difficult to dissipate through conduction with moisture in the air, exacerbating static electricity buildup. Static electricity generated on the surface of packaging boxes can cause dust to re-adhere to the surface, reducing the effectiveness of dust removal. Summary of the Invention

[0004] In view of the problems existing in the prior art, this utility model proposes a dust removal pretreatment device for the surface of packaging boxes.

[0005] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0006] A pretreatment device for dust removal on the surface of a packaging box includes a treatment box and a dust removal brush. The treatment box is characterized by a partition plate dividing it into a dust removal chamber and a drying chamber. The partition plate has a notch for the packaging box to pass through. A vertically downward atomizing nozzle is located on the side wall of the partition plate near the drying chamber. After the packaging box enters the drying chamber through the notch, the atomizing nozzle sprays water onto the packaging box to remove static electricity from its surface.

[0007] In the dust removal pretreatment before folding and forming of the packaging box, the packaging box is first sent into the dust removal cavity of the processing box. In the dust removal cavity, the dust removal brush is used to loosen and brush off stubborn dust hidden in the gap of complex structure due to electrostatic adsorption, adhesion or adhesion of viscous substances by friction with the surface of the packaging box, to complete the preliminary dust removal work. Subsequently, the packaging box enters the drying cavity through the gap on the partition plate. At this time, the atomizing nozzle located on the partition plate close to the side wall of the drying cavity and vertically downward starts to work, spraying water to the packaging box. Since the main cause of static electricity is triboelectricity, the moisture in the spray can increase the conductivity of the surface of the packaging box, so that the static electricity generated by the surface due to friction is conducted away through the water, thereby neutralizing the static electricity and effectively removing the static electricity on the surface of the packaging box.

[0008] The atomizing nozzle is arranged in the drying cavity, which avoids the water in the nozzle entering the dust removal cavity and prevents the environment of the dust removal cavity from being too humid. Because the humid environment will affect the cleaning effect of the brush, such design can ensure that the brush is always in good working condition, maintain the high cleaning ability of the stubborn dust, and ensure the smooth progress of the entire dust removal pretreatment process.

[0009] As a preferred embodiment, a conveying belt is further included, and the left and right side walls of the processing box are respectively provided with an outlet hole and an inlet hole, and the conveying belt enters the processing box from the inlet hole, then sequentially passes through the dust removal cavity, the gap and the drying cavity, and finally exits the processing box from the outlet hole.

[0010] The packaging box to be processed is placed on the conveying belt. The conveying belt enters the processing box from the inlet hole on the left side wall of the processing box, sequentially passes through the dust removal cavity, the gap of the partition plate, the drying cavity, and then exits from the outlet hole on the right side wall. In this process, the conveying belt continuously and stably runs, driving the packaging box to sequentially enter different functional areas.

[0011] In the dust removal cavity, the dust removal brush cleans the surface of the passing packaging box. When the packaging box reaches the drying cavity with the conveying belt, the atomizing nozzle located on the partition plate close to the side wall of the drying cavity vertically downward starts to spray, spraying liquid to the surface of the packaging box to remove static electricity. The whole process relies on the transmission of the conveying belt to realize the orderly flow of the packaging box between different processing links.

[0012] As a preferred embodiment, the top wall of the dust removal cavity is provided with an air gun, and the air gun is located between the dust removal brush and the partition plate, and the lower end face of the dust removal cavity is provided with a dust discharge hole.

[0013] When the surface of the packaging box is pre-processed for dust removal, the conveying belt sends the packaging box from the feeding hole of the left side wall of the processing box into the dust removal cavity. First, the packaging box passes under the dust removal brush, and the dust removal brush loosens and brushes off stubborn dust hidden in the complex structure of the packaging box through the friction between the bristles and the surface of the packaging box due to electrostatic adsorption, adhesion or adhesion. Then, the packaging box continues to move forward with the conveying belt and reaches under the air gun. At this time, the air gun located on the top wall of the dust removal cavity starts to work, and the high-speed airflow sprayed by the air gun further blows away the dust that has been raised but not completely fallen off during the brush cleaning process, as well as some dust loosened by the brush. These dust blown off by the air gun is discharged from the processing box through the dust discharge hole opened at the lower end face of the dust removal cavity.

[0014] As a preferred, the gun head of the air gun is inclined to the side away from the partition plate.

[0015] Since the gun head of the air gun is inclined to the side away from the partition plate, when the air gun is started, the high-speed airflow sprayed impacts the surface of the packaging box at an inclined angle. This inclined airflow not only effectively blows away the dust loosened by the brush, but also promotes the movement of the dust away from the partition plate, and finally discharges the processing box through the dust discharge hole at the lower end face of the dust removal cavity.

[0016] As a preferred, it further includes an electric telescopic rod fixed on the top wall of the dust removal cavity, and the dust removal brush is fixed on the electric telescopic rod.

[0017] The electric telescopic rod can flexibly adjust the distance between the dust removal brush and the surface of the packaging box, and can adapt to packaging boxes of different thicknesses and shapes. Whether it is a thin paper packaging box or a plastic packaging box with a certain thickness, the brush can be adjusted to maintain the best contact state with the surface of the packaging box by adjusting the electric telescopic rod, ensuring efficient dust removal and greatly improving the applicability of the device to diversified packaging products.

[0018] As a preferred, a heating device is arranged in the drying cavity, and a moisture discharge hole is opened on the side wall of the drying cavity.

[0019] The heating device in the drying cavity works to heat the packaging box and the surrounding air, so that the moisture on the surface of the packaging box evaporates rapidly and becomes water vapor. Since hot air has a smaller density and will rise, the water vapor will rise with the hot air and be discharged to the outside of the device through the moisture discharge hole opened on the side wall of the drying cavity. In this process, the moisture on the surface of the packaging box gradually decreases, and finally completes drying to achieve a dry degree suitable for the subsequent folding and forming process.

[0020] As a preferred, anti-slip protrusions are uniformly arranged on the surface of the conveying belt to increase the friction between the conveying belt and the packaging box.

[0021] The anti-skid convex effectively avoids the sliding and deviation of the packaging box during the conveying process, ensures that the packaging box can keep correct relative position and stable contact state with the corresponding processing components in each link such as dust removal, static electricity removal and drying, etc. This makes each packaging box receive consistent and effective pretreatment, ensures the stability and uniformity of the processing effect, and improves the product quality.

DETAILED DESCRIPTION

[0027] For further understanding of the content of the present application, the present application is described in detail in combination with the drawings and embodiments. It should be understood that the embodiments are only used to explain but not limit the present application. EMBODIMENT

[0028] As shown in the drawings, Figs. 1-3 A packaging box surface dust removal pretreatment device, the packaging box surface dust removal pretreatment device mainly comprises a processing box 110 as a main frame. The inside of the processing box 110 is clearly divided into two functional areas of a dust removal cavity 1102 and a drying cavity 1103 by a partition plate 1101. The left and right side walls of the processing box 110 are respectively provided with a feeding hole 1105 and a discharging hole 1106. A conveying belt 140 penetrates into the feeding hole 1105, sequentially passes through the dust removal cavity 1102, the notch 1104 on the partition plate 1101 for the packaging box to pass through, the drying cavity 1103, and finally penetrates out of the discharging hole 1106.

[0029] In the dust removal cavity 1102, the top wall is fixed with an electric telescopic rod 1201, and the lower end of the electric telescopic rod 1201 is connected with a dust removal brush 120, so that the distance between the dust removal brush 120 and the surface of the packaging box can be flexibly adjusted. Meanwhile, the top wall of the dust removal cavity 1102 is also provided with an air gun 150, the air gun 150 is located between the dust removal brush 120 and the partition plate 1101, and the gun head is inclined to the side away from the partition plate 1101, and the lower end surface of the dust removal cavity 1102 is provided with a dust discharge hole 1107.

[0030] In the drying cavity 1103, an atomizing nozzle 130 is vertically downwardly installed on the side wall close to the partition plate 1101, for spraying to remove static electricity after the packaging box enters the drying cavity 1103. In addition, the drying cavity 1103 is also provided with a heating device 160, and the side wall is provided with a moisture discharge hole 1108, for accelerating the evaporation of water on the surface of the packaging box and discharging water vapor.

[0031] The use process and principle of the packaging box surface dust removal pretreatment device in the embodiment are as follows:

[0032] Firstly, the packaging box to be pretreated is placed on the surface of the conveying belt 140. Since the anti-skid protrusions uniformly arranged on the surface of the conveying belt 140 increase the friction between the packaging box and the conveying belt 140, the packaging box can stably enter the treatment box 110 from the feeding hole 1105 in the side wall of the treatment box 110 along with the conveying belt 140.

[0033] When the packaging box enters the dust removal cavity 1102, the electric telescopic rod 1201 adjusts the length according to the condition of the packaging box, so that the dust removal brush 120 is in contact with the surface of the packaging box. Through the friction between the bristles and the surface of the packaging box, the stubborn dust hidden in the complex structure gap of the packaging box due to static adsorption, adhesion or adhesion is loosened and brushed off. Then, the packaging box continues to move forward along with the conveying belt 140 to below the air gun 150, the air gun 150 is started, the inclined gun head sprays high-speed airflow, blows off the dust that is not completely fallen off during the brushing process and the dust loosened due to the contact of the brush, and discharges the dust through the dust discharge hole 1107 in the lower end surface of the dust removal cavity 1102.

[0034] The packaging box after dust removal enters the drying cavity 1103 through the gap 1104 of the partition plate 1101. At this time, the atomizing nozzle 130 starts to work, sprays water to the packaging box, increases the conductivity of the surface of the packaging box by water, and makes the static electricity generated by friction on the surface pass through the water in time to neutralize the static electricity. At the same time, the heating device 160 in the drying cavity 1103 heats the packaging box and the surrounding air, accelerates the evaporation of the water on the surface of the packaging box into water vapor, and drives the water vapor to rise by hot air, and then is discharged to the outside of the device through the exhaust hole 1108 on the side wall of the drying cavity 1103, so that the packaging box reaches a dry degree suitable for the subsequent folding forming process. Finally, the packaging box after the pretreatment leaves the discharge hole 1106 on the right side wall of the processing box 110 with the conveying belt 140, and enters the next production process.

[0035] The device realizes deep dust removal in the dust removal cavity 1102 through the cooperation of multiple components, and timely completes the functions of static electricity elimination and drying in the drying cavity 1103, comprehensively and efficiently solves the problems of dust and static electricity on the surface of the packaging box, greatly improves the pretreatment effect, and provides a high-quality surface basis for the subsequent folding forming process, effectively improving the product quality.

[0036] The atomizing nozzle 130 is arranged in the drying cavity 1103, which effectively avoids the water from entering the dust removal cavity 1102, prevents the dust removal cavity 1102 from being excessively humid, and affects the cleaning effect of the brush, ensures that the brush is always in good working condition, and maintains the efficient cleaning ability of the stubborn dust. At the same time, cross contamination between the two functional areas is avoided, and the reliability of the entire pretreatment process is ensured.

[0037] In summary, the above is only a preferred embodiment of the present embodiment, and any changes and modifications made within the scope of the patent application of the present embodiment shall be within the scope of the present embodiment.
