Description

Technical Field

[0001] The utility model belongs to the technical field of dust removal in corrugated board production, and particularly relates to a dust removal device for corrugated board production. Background Art

[0002] Corrugated board is a multi-layer adhesive body, which is composed of at least one layer of wavy core paper sandwich and cardboard. Due to its advantages of light weight, high strength and recyclability, it is widely used in the packaging and transportation fields of various products. During the production and processing of corrugated board, operations such as cutting and printing are required. During the cutting and conveying process of corrugated board, dust, paper scraps and other impurities will inevitably adhere to the outer surface of the corrugated board. These impurities will have an adverse impact on the subsequent processing of the corrugated board. The dust removal device for corrugated board production is a type of equipment used to remove dust from the cut corrugated board.

[0003] The Chinese utility model patent with the patent number CN217671721U discloses a dust removal device for corrugated board production, which includes a corrugated board and an electrostatic dust removal box. Electrostatic dust removal boxes are arranged above and below the corrugated board. A support frame is arranged on one side of the corrugated board. A distance adjustment component is installed on the support frame along the vertical direction. Two sliding seats on the distance adjustment component are respectively connected to the two electrostatic dust removal boxes in one-to-one correspondence through connecting seats. A rotating part is installed on the connecting seat. An installation frame is rotatably connected to the inside of the electrostatic dust removal box through a rotating shaft. Two independently controlled electrostatic dust removal rods are installed on the outer wall of the installation frame. A laser measuring part is installed between the two sliding seats. A main control device is installed on the support frame. Combining the measurement signal of the laser measuring part, the main control device controls the distance adjustment component to automatically adjust, with fast adjustment, without the need to stop the machine for processing the electrostatic dust removal rods, ensuring the production efficiency of the corrugated board.

[0004] The dust removal device for corrugated board production disclosed in this application uses electrostatic dust removal rods to perform electrostatic dust removal on the dust and paper scraps on the surface of the corrugated board. Although this method can perform dust removal on the corrugated board, the effect of removing dust and paper scraps that adhere firmly to the surface of the corrugated board is poor.

[0005] Therefore, in view of the above technical problems, it is necessary to provide a dust removal device for corrugated board production.

[0006] The information disclosed in this background art section is only intended to enhance the overall understanding of the present utility model and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art.

Detailed implementation manners

[0029] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] As Figures 1 to 5As shown in the figure, a dust removal device for corrugated cardboard production in an embodiment of the present utility model includes: a box frame 1, a pair of belt conveyor components 2, and a cleaning type negative pressure dust removal component 3.

[0031] As Figure 1 shown, a pair of belt conveyor components 2 are symmetrically assembled in the box frame 1. The corrugated cardboard to be dust-removed is frictionally conveyed through the belt conveyor components 2.

[0032] As Figure 1 shown, the belt conveyor component 2 includes a pair of friction conveyor belts 201, and the pair of friction conveyor belts 201 are symmetrically arranged on one side of the box frame 1. The corrugated cardboard is frictionally conveyed by controlling the movement of the pair of friction conveyor belts 201, which provides convenience for the subsequent cleaning and dust removal process of the corrugated cardboard.

[0033] Specifically, the gap between the pair of friction conveyor belts 201 is adapted to the thickness of the corrugated cardboard. It is convenient to frictionally convey the corrugated paper by controlling the movement of the pair of friction conveyor belts 201.

[0034] As Figure 1 shown, both ends of the box frame 1 are fixedly connected with supporting plates 203, and the pair of supporting plates 203 are arranged on both sides of the friction conveyor belt 201. The corrugated cardboard to be dust-removed is supported and limited by the pair of supporting plates 203.

[0035] It should be noted that the upper surface of the supporting plate 203 is at the same horizontal plane as the upper surface of the friction conveyor belt 201 arranged below.

[0036] As Figure 1 shown, multiple groups of uniformly distributed conveyor belt guide wheels 202 are assembled in each of the pair of friction conveyor belts 201, and the multiple groups of conveyor belt guide wheels 202 are all rotatably connected to the side wall of the box frame 1. The multiple groups of conveyor belt guide wheels 202 play a role in tensioning, limiting and driving control of the friction conveyor belt 201.

[0037] As Figure 5 shown, a conveyor motor 204 is fixedly assembled on the outside of the box frame 1, and the output shaft of the conveyor motor 204 is in transmission connection with the conveyor belt guide wheel 202. The conveyor motor 204 plays a role in providing power. By controlling the operation of the conveyor motor 204, the conveyor belt guide wheel 202 is rotationally driven, so as to facilitate the driving control of the movement state of the friction conveyor belt 201.

[0038] Among them, the conveyor motor 204 is commercially available and can be directly purchased and used.

[0039] As Figure 5As shown, a pair of synchronous gears 205 are mounted on the outer side of the box frame 1, the pair of synchronous gears 205 are meshed, and the pair of synchronous gears 205 are respectively connected to the conveyor belt guide wheels 202 in the pair of friction conveyor belts 201. Through the mutual cooperation of the pair of synchronous gears 205, the pair of friction conveyor belts 201 can perform friction movement on the corrugated cardboard in the same direction.

[0040] like Figures 2 to 3 As shown, the sweeping negative pressure dust removal assembly 3 is fixedly assembled in the box frame 1, and the sweeping negative pressure dust removal assembly 3 includes an upper sweeping roller 301, which is assembled between multiple groups of conveyor belt guide wheels 202, and a lower sweeping roller 302 is assembled below the upper sweeping roller 301, and the upper sweeping roller 301 and the lower sweeping roller 302 are arranged correspondingly to a pair of friction conveyor belts 201. The upper sweeping roller 301 and the lower sweeping roller 302 cooperate with each other to clean the corrugated cardboard frictionally conveyed between the pair of friction conveyor belts 201.

[0041] like Figures 2 to 3 As shown, an upper dust collecting cover 303 is mounted above the upper cleaning roller 301. The upper dust collecting cover 303 guides and limits the impurities swept out by the upper cleaning roller 301. A lower dust collecting cover 304 is mounted below the lower cleaning roller 302. The lower dust collecting cover 304 guides and limits the impurities swept out by the lower cleaning roller 302.

[0042] like Figures 2 to 5 As shown, a pair of linkage gears 305 are mounted on the outer side of the box frame 1, the pair of linkage gears 305 are meshed, and the pair of linkage gears 305 are fixedly connected to the upper cleaning roller 301. The pair of linkage gears 305 drive the pair of upper cleaning rollers 301 to rotate in the opposite direction, thereby cleaning the surface of the corrugated cardboard conveyed by the friction conveyor belt 201.

[0043] like Figures 2 to 5 As shown, one end of the upper cleaning roller 301 located outside the box frame 1 is fixedly connected with a driving gear 306. The upper cleaning roller 301 is rotationally driven by the driving gear 306.

[0044] like Figures 2 to 5 As shown, a transmission gear 307 is meshed on one side of the driving gear 306, and the transmission gear 307 is fixedly connected to the conveyor belt guide wheel 202. The upper cleaning roller 301 can rotate in the opposite direction to the conveyor belt guide wheel 202 through the cooperation between the driving gear 306 and the transmission gear 307, thereby ensuring the stability of the upper cleaning roller 301 in cleaning the surface of the corrugated cardboard.

[0045] like Figures 2 to 4As shown, a pair of lower dust collection pipes 308 are fixedly connected below the lower dust collection hood 304. The lower dust collection pipes 308 play a role in connecting the lower dust collection hood 304 and the dust collection box 310. Thus, the impurities swept out by the lower cleaning roller 302 are collected and diverted by extracting the gas in the lower dust collection hood 304 through the lower dust collection pipes 308.

[0046] As Figures 2 to 4 shown, upper dust collection pipes 309 are fixedly connected and communicated between the upper dust collection hood 303 and the pair of lower dust collection pipes 308. The upper dust collection pipes 309 connect the upper dust collection hood 303 and the lower dust collection pipes 308, thus facilitating the negative pressure collection and diversion of the impurities swept out by the upper cleaning roller 301.

[0047] As Figures 2 to 4 shown, one end of the pair of lower dust collection pipes 308 far from the lower dust collection hood 304 is fixedly connected and communicated with a dust collection box 310. The dust collection box 310 provides a negative pressure dust collection space.

[0048] As Figures 2 to 4 shown, a pair of dust filtering mesh cylinders 311 are fixedly assembled in the dust collection box 310. The pair of dust filtering mesh cylinders 311 divide the negative pressure dust collection space into a dust-containing diversion cavity 312 and a dust filtering diversion cavity 313, thus facilitating the filtration treatment of the air containing impurities introduced by the lower dust collection pipes 308 and the upper dust collection pipes 309.

[0049] Specifically, a dust-containing diversion cavity 312 and a dust filtering diversion cavity 313 are formed by the cooperation between the pair of dust filtering mesh cylinders 311 and the dust collection box 310. The dust-containing diversion cavity 312 temporarily stores and diverts the air containing impurities. The filtered air is exported through the dust filtering diversion cavity 313.

[0050] As Figures 2 to 4 shown, a pair of exhaust pipes 314 are fixedly connected to the bottom of the dust collection box 310, and both of the pair of exhaust pipes 314 are communicated with the dust filtering diversion cavity 313. The exhaust pipes 314 play a role in conducting gas for the dust filtering diversion cavity 313. At the same time, the exhaust pipes 314 play a role in assembling and limiting the exhaust fans 315.

[0051] As Figures 2 to 4 shown, a number of exhaust fans 315 are fixedly assembled in each of the pair of exhaust pipes 314. The gas in the dust collection box 310 is exported by controlling the operation of the number of exhaust fans 315.

[0052] During specific use, the operation of the conveyor motor 204 is controlled to drive the rotation of the single conveyor belt guide wheel 202, so that the single friction conveyor belt 201 moves under the driving action of the conveyor belt guide wheel 202. The mutual engagement of a pair of synchronous gears 205 enables the pair of friction conveyor belts 201 to move in the same direction. The corrugated cardboard to be dust-removed is placed on the support plate 203 for preliminary support, and the corrugated cardboard is frictionally moved synchronously with the movement of the friction conveyor belt 201 by the pair of friction conveyor belts 201, thus realizing the conveying process of the corrugated cardboard.

[0053] Meanwhile, during the rotation of the conveyor belt guide wheel 202, it can drive the rotation of the transmission gear 307. The single upper cleaning roller 301 rotates in the opposite direction to the rotation direction of the conveyor belt guide wheel 202 under the meshing action of the driving gear 306 and the transmission gear 307. And the pair of upper cleaning rollers 301 can rotate in opposite directions under the meshing action of a pair of linkage gears 305, and the impurities adhering to the outer surface of the corrugated cardboard are cleaned by the reverse rotation of the pair of upper cleaning rollers 301.

[0054] The air in the dust filtering and guiding cavity 313 can be extracted by controlling the operation of several exhaust fans 315. By extracting the air, the upper dust collecting cover 303 and the lower dust collecting cover 304 are also in the state of air extraction under the action of the lower dust collecting pipe 308 and the upper dust collecting pipe 309, so that the impurities cleaned by the upper cleaning roller 301 and the lower cleaning roller 302 can move into the dust-containing guiding cavity 312 along with the air flow, and are discharged along the exhaust pipe 314 after being filtered by the dust filtering mesh cylinder 311, thus completing the cleaning and dust removal process of the corrugated cardboard.

[0055] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
