Description

Technical Field

[0001] The utility model relates to the technical field of papermaking, in particular to a dust removal device for a coated white board paper rewinder. Background Art

[0002] The surface of the paper web needs to be dusted in the rewinding machine for coated white board paper. The prior art usually allows the paper web to pass through a dust collection chamber of a dust removal device, which is connected to a number of dust collection pipes, which are connected to a dust collector (e.g., a bag dust collector). During operation, the dust collection chamber generates negative pressure to achieve the purpose of dust removal. However, the dust collection effect achieved by such a technical solution is general, and the surface of the paper web will contact the dust collection chamber, which may have a certain degree of impact on the surface of the paper web. In view of the above technical problems, the utility model proposes a new technical solution that can achieve contactless dust removal on the surface of the paper web in the rewinding machine for coated white board paper.

[0003] It can be seen that the existing technology still needs to be improved and enhanced. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide a dust removal device for a coated white board paper rewinder, aiming to solve the technical problems in the prior art that the dust removal device for a coated white board paper rewinder has a general dust suction effect and contacts the surface of the paper web.

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

[0006] A dust removal device for a coated white paper rewinder comprises a dust collector and a dust suction pipe, wherein both ends of the dust suction pipe are connected to an inlet end of the dust collector through pipelines; a row of first through holes, a row of second through holes and a row of third through holes are arranged on the dust suction pipe along the length direction; each first through hole is arranged in the form of an equilateral triangle with two adjacent second through holes; each third through hole is arranged in the form of an equilateral triangle with two adjacent second through holes.

[0007] Furthermore, in the dust removal device of the coated white board paper rewinder, the first through holes and the third through holes are arranged alternately in the length direction of the dust suction pipe.

[0008] Furthermore, in the dust removal device of the coated white board paper rewinder, the second through holes are arranged at the same intervals.

[0009] Furthermore, in the dust removal device of the coated white board paper rewinder, each of the first through hole, the second through hole and the third through hole is a circular hole.

[0010] Furthermore, in the dust removal device of the coated white board paper rewinder, the apertures of each first through hole, the second through hole and the third through hole are equal.

[0011] Furthermore, in the dust removal device of the coated white board paper rewinder, the dust suction pipe is a stainless steel pipe.

[0012] Furthermore, in the dust removal device of the coated white board paper rewinder, the dust collector is a bag dust collector.

[0013] Beneficial effect: The utility model provides a dust removal device for a coated white paper rewinder. Compared with the prior art, by providing a dust suction pipe and a dust collector, and providing a row of first through holes, a row of second through holes, and a row of third through holes on the dust suction pipe, the surface of the paper web at the coated white paper rewinder can be dusted without contact, which ensures a good dust removal effect and does not affect the surface quality of the paper web. In addition, the dust suction pipe in the present application has a simple structure, is easy to install, and is easy to maintain. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The utility model provides a dust removal device for a coated white paper rewinder. In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0018] See also Figure 1 and Figure 2 , the utility model provides a dust removal device for a coated white board paper rewinder. The accompanying drawings are only used to explain the structural principles and are not proportional to the actual products. The accompanying drawings only depict the structures related to the invention point of this application, and some conventional structures (such as dust collectors) are not specifically depicted. The terms "first", "second", etc. described herein are merely different names for similar structures for the convenience of explanation, and are not intended to limit this application. For the sake of convenience, this article inevitably uses some directional words, but these directional words are not intended to limit this application, because they can be set to different directions in actual applications. The "multiple" or "several" described herein refers to an indefinite number, because the number of structures referred to is not an invention point, and therefore is not specifically limited.

[0019] The dust removal device of the coated white paper rewinding machine includes a dust collector (not shown in the figure) and a dust suction pipe 1, and the two ends of the dust suction pipe are connected to the inlet end of the dust collector (not shown in the figure) through a pipe 2; a row of first through holes 101, a row of second through holes 102 and a row of third through holes 103 are arranged along the length direction of the dust suction pipe; each first through hole is arranged in an equilateral triangle with two adjacent second through holes; each third through hole is arranged in an equilateral triangle with two adjacent second through holes. The specific number of the above three rows of through holes (i.e., the first through hole, the second through hole, and the third through hole) is not limited, because the number itself is not the invention point of this application.

[0020] Preferably, if Figure 2 As shown, the first through hole and the third through hole are arranged alternately in the length direction of the dust suction pipe. Since the first through hole and the third through hole are arranged alternately, the dust suction coverage of the dust suction pipe is wider.

[0021] Preferably, the second through holes are arranged at the same intervals, so that the dust suction effect of the dust suction tube at each location along its length direction is substantially the same.

[0022] Preferably, each of the first through hole, the second through hole and the third through hole is a circular hole.

[0023] Preferably, the diameters of each of the first through hole, the second through hole and the third through hole are equal, and the diameter is preferably 12 mm. This arrangement further ensures that the dust suction effect of the dust suction pipe at each location along its length direction is substantially the same.

[0024] The dust suction tube 1 is preferably a round tube, and the tube diameter is preferably 150 mm.

[0025] Preferably, the dust suction pipe 1 is a stainless steel pipe to ensure that the dust suction pipe has a long service life.

[0026] Preferably, the dust collector is a bag dust collector, the fan of the bag dust collector has at least two air inlets (not shown in the figure), and the pipes (preferably hoses) at both ends of the dust suction pipe are respectively connected to the air inlets of the fan of the bag dust collector. The bag dust collector itself is a prior art, and its structure is not shown in the drawings.

[0027] like Figure 3 As shown, in actual application, the dust suction pipe 1 is not in direct contact with the paper web 9, and the three rows of through holes are facing the paper web. After the bag filter is running, negative pressure is generated in the dust suction pipe, and each of the first through hole, the second through hole and the third through hole will suck air inward. When the paper web passes through the dust suction pipe, paper hair, paper powder, etc. on the surface of the paper web are sucked into the dust suction pipe and sent to the bag filter, thereby achieving dust removal on the surface of the paper web.

[0028] 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 utility model, and all these changes or substitutions should fall within the protection scope of the utility model.
