Description

Technical Field

[0001] The utility model relates to the technical field of dust removal, in particular to a water bath type dust removal device for a rewinder. Background Art

[0002] The paper web on the downwinder is wound around the bottom rollers at the bottom of the machine. The paper roll then passes from the unwinder over the guide rollers and into the slitting device, where it passes over the support rollers before being wound onto the paper core. During high-speed operation, the slitting blades generate paper lint as the paper web is cut. Some of this lint floats along with the paper into the bottom pit. As the paper passes through the pit, it adheres to the paper and causes subsequent printing quality issues such as linting and dusting. In response to these technical issues, the present utility model proposes a novel technical solution for removing the lint generated by the rewinder and ensuring paper quality. Utility Model Content

[0003] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a water bath dust removal device for a rewinder, aiming to solve the technical problem in the prior art that paper fibers generated by the rewinder easily adhere to the paper and thus affect the quality of the paper.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A water bath dust removal device for a rewinder comprises a dust removal box, a water inlet pump, and a bottom pit arranged below the rewinder, the dust removal box comprising a water outlet pipe, an air inlet pipe, and an air outlet pipe; the bottom pit is provided with an outlet pipe, the outlet pipe of the bottom pit is provided with a fan, the outlet pipe of the fan is connected to the air inlet pipe of the dust removal box; the outlet pipe of the water inlet pump is connected to a plurality of spray pipes, each of which is inserted into the dust removal box, and each spray pipe is provided with a plurality of spray holes.

[0006] Furthermore, in the water bath dust removal device for the rewinder, each spray hole of each spray pipe faces the air inlet pipe of the dust removal box.

[0007] Furthermore, in the water bath dust removal device of the rewinder, a total of several rows of spray pipes are provided, and the spray pipes of any two adjacent rows are staggered.

[0008] Furthermore, in the water bath dust removal device of the rewinder, the dust removal box includes a box body, an expansion section and a contraction section, the air inlet pipe is connected to the expansion pipe, and the air outlet pipe is connected to the contraction section.

[0009] Furthermore, in the water bath dust removal device for the rewinder, the water outlet pipe of the dust removal box is connected to a water tank, and the outlet pipe of the water tank is connected to a drainage pump.

[0010] Beneficial effect: The utility model provides a water bath dust removal device for a rewinder. Compared with the existing technology, by setting components such as a fan, a dust removal box, a water pump, and a spray pipe, the paper hair generated by the rewinder can be sucked and dusted in a water bath, thereby avoiding the paper hair from adhering to the paper and ensuring the quality of the paper.

[0013] The present invention provides a water bath dust removal device for a rewinding machine. To make the purpose, technical solution, and effects of the present invention clearer and more specific, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only intended to explain the present invention and are not intended to limit the present invention.

[0014] See also Figure 1 and Figure 2 The present invention provides a water bath dust removal device for a rewinder. The accompanying drawings are only used to illustrate the structural principles and are not to scale with the actual product. The accompanying drawings only depict structures relevant to the invention of this application, and some conventional structures are not depicted.

[0015] A water bath dust removal device for a rewinder includes a dust removal box 3, a water inlet pump 4, and a pit 1 disposed below the rewinder. The dust removal box includes a water outlet pipe 303, an air inlet pipe 301, and an air outlet pipe 302. The pit is provided with an outlet pipe 11, which is provided with a fan 2, the outlet pipe of which is connected to the air inlet pipe 301 of the dust removal box. The outlet pipe 41 of the water inlet pump is connected to a plurality of spray pipes 49, each of which is inserted into the dust removal box and has a plurality of spray holes ( Figure 1 The spray holes are not drawn in the figure, and the spraying water is schematically drawn in).

[0016] Preferably, each spray hole of each spray pipe faces the air inlet pipe of the dust removal box. This arrangement allows the water sprayed from each spray hole to directly contact the air flow from the pit, thereby improving the dust removal effect.

[0017] like Figure 2 As shown, preferably, there are several rows of spray pipes, and the spray pipes of any two adjacent rows are staggered. The accompanying drawings schematically illustrate several spray pipes, and the present application does not specifically limit the specific number of spray pipes.

[0018] Furthermore, the dust box includes a box body 32, an expansion section 31, and a contraction section 33. The air inlet pipe is connected to the expansion pipe, and the air outlet pipe is connected to the contraction section. This arrangement reduces the speed of the airflow from the pit after entering the dust box, prolonging the airflow's residence time in the dust box and further improving the dust removal effect.

[0019] Preferably, the water outlet pipe of the dust removal box is connected to a water tank 5, and the outlet pipe of the water tank is connected to a drainage pump 6. This arrangement facilitates the collection of waste water after dust removal and transports it to other water points to avoid wasting water resources.

[0020] During operation, the fan creates negative pressure in the pit, drawing paper fluff from the rewinder through the pit and sending it to the dust removal box, where it comes into contact with spray water, creating a water bath for dust removal. The airflow, having passed through the dust removal box, is then discharged through the dust removal box's outlet duct. The spray water falls to the bottom of the dust removal box, drains into a sink, and is then pumped to other water points in the factory.

[0021] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and the utility model concept of the present invention, and all these changes or substitutions should fall within the scope of protection of the present invention.
