Description

Technical Field

[0001] The invention relates to the technical field of paperboard production and processing, in particular to a paperboard drying cylinder surface cleaning device. Background Art

[0002] The invention and application of corrugated paper has a history of more than 100 years. It has the advantages of low cost, light weight, easy processing, high strength, excellent printing adaptability, and convenient storage and transportation. More than 80% of corrugated paper can be recycled. Corrugated paper can be used as packaging for food or digital products. It is relatively environmentally friendly and widely used.

[0003] At present, in the production process of corrugated paper, the bonding and shaping of single-sided corrugated board and face paper is completed on the drying cylinder. In the existing corrugated board production process, the face paper of the corrugated board is tightly attached to the cylinder surface with the face paper facing downward and moves forward under the rotation of the cylinder surface. There are also wool belts and rollers on the corrugated board to apply a certain pressure to the corrugated board and the cylinder surface to ensure that the corrugated board is always in contact with the cylinder surface during the process of passing through the dryer. In this process, pollutants on the face paper of the corrugated board will be aggregated on the cylinder surface, especially the glue overflowed from both sides will be aggregated on the cylinder surface. It is very difficult to clean and the machine must be stopped before it can be done; in the existing technology, most of the cleaning is done manually with a scraper, and the middle part is difficult to clean, and it is easy to damage the cylinder surface when cleaning with a scraper manually; if the surface of the hot plate is seriously damaged, it must be scrapped, because the hot plate with damaged surface will scratch the corrugated cardboard surface paper; there are also many manufacturers who use a scraper to contact the cylinder surface to scrape off the contaminants on the cylinder surface, but the cylinder surface does not always have contaminants, and long-term contact will cause great damage to the cylinder surface and the scraper; how to make the scraper clean the cylinder surface only when there are contaminants on the cylinder surface is a problem that needs to be solved at present.

BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Figure 1 It is a schematic diagram of the structure of the cleaning device described in an embodiment of the present invention. DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0024] Example

[0025] like Figure 1 As shown, the paperboard drying cylinder surface cleaning device of this embodiment comprises:

[0026] A cleaning mechanism 10, wherein the cleaning mechanism 10 is used to clean pollutants on the cylinder surface;

[0027] and a driving mechanism 20, wherein the driving mechanism 20 is used to drive the cleaning mechanism 10 to clean the cylinder surface;

[0028] and a detection mechanism 30, the detection mechanism 30 is used to detect whether there are contaminants on the cylinder surface and start the driving mechanism 20 when there are contaminants on the cylinder surface;

[0029] and a fixing frame, wherein the fixing frame is used to fix the cleaning mechanism 10, the driving mechanism 20, and the detecting mechanism 30;

[0030] The fixing frame includes a first fixing plate 41 and a second fixing plate 42; the first fixing plate 41 is arranged perpendicular to the cylinder surface; the second fixing plate 42 is perpendicular to the first fixing plate 41 and is fixedly arranged on one side of the first fixing plate 41, the cleaning mechanism 10 is arranged on the side of the first fixing plate 41 where the second fixing plate 42 is arranged, and the cleaning mechanism 10 slides up and down along the first fixing plate 41, and a detection mechanism 30 is arranged on the other side of the first fixing plate 41, and the detection mechanism 30 slides up and down along the first fixing plate 41.

[0031] During the rotation of the cylinder surface, if there are contaminants on the cylinder surface, the cylinder surface at that location will bulge, and when it rotates to the detection mechanism 30, the detection mechanism 30 will rise, thereby starting the driving mechanism 20 and driving the cleaning mechanism 10 to descend to clean the cylinder surface; when there are no contaminants on the cylinder surface, the cleaning mechanism 10 is separated from the cylinder surface to prevent long-term cleaning of the cylinder surface from causing heavy wear on the cylinder surface and the cleaning mechanism 10.

[0032] like Figure 1 As shown, the driving mechanism 20 includes: an electric telescopic rod 21 and a travel switch 22 for controlling the extension and retraction of the electric telescopic rod 21; the travel switch 22 is triggered by the detection mechanism 30 to control the extension and retraction of the electric telescopic rod 21; the detection mechanism 30 rises under the action of the protrusion of the contaminant on the cylinder surface and contacts the travel switch 22, so that the electric telescopic rod 21 is extended, and the cleaning mechanism 10 is driven to clean the cylinder surface. After the electric telescopic rod 21 is extended to the maximum, it will automatically shorten to the initial position.

[0033] like Figure 1 As shown, the cleaning mechanism 10 is provided with a lifting rod 11 used in conjunction with the electric telescopic rod 21, and the lifting rod 11 is controlled to rise and fall by the electric telescopic rod 21; the lifting rod 11 is vertically arranged with the electric telescopic rod 21, and a first roller 12 is arranged at one end of the lifting rod 11 close to the electric telescopic rod 21, and the electric telescopic rod 21 is arranged in a trapezoidal shape at one end close to the lifting rod 11; when the electric telescopic rod 21 is extended, because the electric telescopic rod 21 is arranged in a trapezoidal shape at one end close to the lifting rod 11, the lifting rod 11 first descends at a uniform speed on the inclined surface of the trapezoid, and when it reaches the bottom surface of the trapezoid, the lifting rod 11 keeps its position, and the electric telescopic rod 21 starts to shorten after being extended to the longest, and the lifting rod 11 keeps its position first, and then rises at a uniform speed to the initial position on the inclined surface of the trapezoid. In this process, the lifting rod 11 will remain stationary for a period of time on the bottom surface of the trapezoid. During this period of time, the cleaning mechanism 10 keeps in contact with the cylinder surface and cleans the cylinder surface, thereby avoiding the problem that the cleaning mechanism 10 cannot clean the cylinder surface after scraping, and improving the cleaning ability of the cleaning device on the cylinder surface.

[0034] like Figure 1 As shown, a plurality of return springs 13 in a stretched state are arranged between the cleaning mechanism 10 and the second fixing plate 42; the arrangement of the return springs 13 enables the cleaning mechanism 10 to return to the initial position after cleaning the cylinder surface.

[0035] The second fixing plate 42 is provided with a limiting mechanism; the limiting mechanism enables the cleaning mechanism 10 to just contact the cylinder surface when cleaning the cylinder surface, without generating excessive pressure at the contact point between the cleaning mechanism 10 and the cylinder surface, thereby causing unnecessary damage to the cylinder surface and the cleaning mechanism 10.

[0036] like Figure 1As shown, the cleaning mechanism 10 includes: a storage box 14 and a scraper 15 arranged at the bottom of the storage box 14; the angle between the direction from the blade head to the blade tail of the scraper and the rotation direction of the cylinder surface is an acute angle; a storage box 11 is provided for storing the scraped pollutants to prevent the pollutants from sticking to the cylinder surface again, and the angle between the direction from the blade head to the blade tail of the scraper 15 and the rotation direction of the cylinder surface is an acute angle, so that the scraper can clean the cylinder surface more cleanly.

[0037] like Figure 1 As shown, the number of the scrapers 15 is at least two, so that the cleaning mechanism 10 can scrape the pollutants on the cylinder surface more cleanly, avoiding the situation where the pollutants are not scraped cleanly, which affects the normal operation of the drying cylinder.

[0038] like Figure 1 As shown, the detection mechanism 30 includes: a sliding rod 31, a roller support rod 32 and a second roller 33; the roller support rod 32 is arranged at one end of the sliding rod 31 close to the cylinder surface, and the second roller 33 is arranged at one end of the roller support rod 32 away from the sliding rod 31.

[0039] The sliding rod 31 is connected to the roller support rod 32 by a spring; when the cylinder surface contaminant protrudes too high, the detection mechanism 30 rises too high, and the sliding rod 31 directly hits the travel switch 22, causing damage to the travel switch 22. The spring connection between the sliding rod 31 and the roller support rod 32 can play a buffering role when the cylinder surface contaminant protrudes too high, thereby preventing the sliding rod 31 from damaging the travel switch 22.

[0040] It should be noted that, in this article, if there are first and second, etc., relational terms are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
