Description

Technical Field

[0001] The utility model relates to the technical field of paper-faced gypsum board manufacturing equipment, and particularly relates to a cleaning device for a gypsum board forming belt. Background Art

[0002] With the development of the gypsum board industry, the requirements for the appearance quality of gypsum boards in the market are further improved. There are many reasons affecting the appearance quality of gypsum boards, such as surface pits, white gypsum prints on the paper surface, etc.

[0003] Most of the white gypsum prints on the paper surface are caused by block breakage (lumps in the slurry cause the facing paper to be scratched, resulting in the slurry leaking onto the belt), or the gypsum slurry overflows onto the belt during the process of pulling the plate head. The residual gypsum slurry on the belt will be contaminated onto the facing paper, thereby generating substandard boards and affecting the appearance. In order to reduce the generation of the above-mentioned substandard boards, in the prior art, manual wiping or regular high-pressure water flushing of the belt is often used for cleaning. However, the entire belt is up to one hundred meters long, and the cleaning process is not only time-consuming and laborious, but also has poor effects and is extremely likely to affect production.

[0004] However, during the cleaning process of the caked gypsum on the forming belt, since the caked gypsum cleaned by various cleaning devices all scatters onto the factory floor, it is extremely likely to pollute the working environment and increase the later cleaning burden. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a cleaning device for a gypsum board forming belt, so as to solve the technical problem that when using a scraper to scrape and clean the caked gypsum on the forming belt in the prior art, it is not convenient to centrally collect and process the scraped objects, thereby affecting the cleaning efficiency.

[0006] To solve the above technical problem, the utility model specifically provides the following technical solutions:

[0007] The utility model provides a cleaning device for a gypsum board forming belt, including: a mounting base plate, which is fixedly arranged in the lower area of the forming belt, and the forming belt is driven by a transmission roller; a cleaning assembly, which is arranged near the transmission roller on the lower side of the forming belt for removing the caked gypsum on the forming belt. The cleaning assembly includes an arc-shaped plate, and the arc-shaped plate is fixedly connected to the mounting base plate through a support vertical plate; the radian of the arc-shaped plate is the same as the radian of the bending part of the forming belt, and the distance between the arc-shaped plate and the forming belt is equal. On one side of the inner arc wall of the arc-shaped plate, a scraper and a brush plate are arranged at intervals.

[0008] Further, guiding channels penetrating through the lower side wall of the limiting plate in its width direction are provided. A plurality of guiding channels are arranged at equal intervals along the length direction of the limiting plate. When the scraping plate abuts against the limiting plate, the caked gypsum can be led out of the surface of the scraping plate through the guiding channels. Among them, guiding grooves penetrating through the upper side wall of the scraping plate in its width direction are provided, and the cross-sections of the guiding grooves and the guiding channels are the same.

[0009] Further, the overlapping degree between the guiding channels and the guiding grooves is adjustable. Among them, the scraping plate and the supporting plate are connected by a telescopic shaft rod, and the telescopic adjustment of the telescopic shaft rod can stagger the positions between the scraping plate and the limiting plate to change the overlapping degree between the guiding channels and the guiding grooves.

[0010] Further, the guiding channels and the guiding grooves intersect with each other so that the caked gypsum forms a guiding path with high and low intersections on the scraping plate.

[0012] Further, a brushing plate is arranged in the downstream area of the scraping plate, and a detachable hard brush head is provided at the end of the brushing plate for cleaning the forming belt.

[0013] Further, a collecting hopper is provided on the mounting base plate. The collecting hopper is arranged at the downstream outlet end of the arc-shaped plate and is used for receiving the caked gypsum.

[0014] Further, a supporting inclined plate is provided on the supporting vertical plate for supporting the arc-shaped plate. Among them, a blocking side plate bent upward is provided on the arc-shaped plate, and at least part of the blocking side plate is arranged on both sides of the downstream of the arc-shaped plate. The end of the blocking side plate is bent inward by 30° to form a guiding plate for gathering the caked gypsum.

[0015] The utility model has the following beneficial effects compared with the prior art:

[0016] By arranging a cleaning assembly at the head end of the forming belt, the utility model can clean the caked gypsum on the forming belt along the conveying path, and at the same time can guide and collect the caked gypsum that falls off during cleaning, improving the cleaning and collection effect of the caked gypsum on the forming belt, avoiding the continuous scattering of the caked gypsum onto the factory floor and polluting the working environment, and increasing the cleaning burden of workers.

[0026] 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 fall within the protection scope of the present invention.

[0027] As Figure 1 shown, the present invention provides a cleaning device for a gypsum board forming belt, including:

[0028] An installation base plate 10 is fixedly arranged in the lower area of the forming belt 30, and the forming belt 30 is driven by a transmission roller 31;

[0029] A cleaning assembly 20 is arranged near the transmission roller 31 on the lower side of the forming belt 30 for removing the agglomerated gypsum on the forming belt 30. The cleaning assembly 20 includes an arc-shaped plate 21, and the arc-shaped plate 21 is fixedly connected to the installation base plate 10 through a support vertical plate 26; the radian of the arc-shaped plate 21 is the same as the radian of the bent part of the forming belt 30, and the distance between the arc-shaped plate 21 and the forming belt 30 is equal. A scraping plate 22 and a brushing plate 23 are arranged at intervals on one side of the inner arc wall of the arc-shaped plate 21. The scraping plate 22 is movably arranged on the arc-shaped plate 21, and the brushing plate 23 is fixedly arranged along the normal plane of the arc-shaped plate 21;

[0030] Wherein, support plates 24 along its normal plane are symmetrically arranged at both ends of the arc-shaped plate 21, and both ends of the scraping plate 22 are respectively pivotally connected to the support plates 24. A spacing for the scraping plate 22 to rotate is left between one side edge of the scraping plate 22 and the arc-shaped plate 21. A limiting plate 25 along the normal plane of the arc-shaped plate 21 is arranged on the arc-shaped plate 21, and the limiting plate 25 is used to limit the rotation range of the scraping plate 22, and the limiting plate 25 is arranged in the upstream area of the scraping plate 22.

[0031] A cleaning device for a gypsum board forming belt provided by the present utility model can clean the agglomerated gypsum on the forming belt 30 along the conveying path by arranging the cleaning assembly 20 at the head end of the forming belt 30, and can also guide and collect the agglomerated gypsum that has fallen after cleaning, improving the cleaning and collection effect of the agglomerated gypsum on the forming belt 30, avoiding the continuous scattering of the agglomerated gypsum onto the factory floor and polluting the working environment, and increasing the cleaning burden of workers.

[0032] In the actual use process of the cleaning assembly 20 provided in this embodiment, the scraping edge of the scraping plate 22 abuts against the forming belt 30, and the other end of the scraping plate 22 that does not abut against the forming belt 30 is limited by the limiting plate 25, so as to use the scraping plate 22 to scrape the moving forming belt 30 to clean the agglomerated gypsum thereon. After the forming belt 30 runs one week, that is, after the scraping operation of the entire forming belt 30 is completed, the scraping plate 22 is rotated to make the scraped and collected agglomerated gypsum fall onto the arc-shaped plate 21 for centralized collection, avoiding the random scattering of the agglomerated gypsum on the factory floor after being scraped.

[0033] In the above embodiment, the limitation of the scraping plate 22 depends on its effect when abutting against the limiting plate 25, and when the two abut, the export path of the agglomerated gypsum cleared is blocked, so that the agglomerated gypsum is easily blocked by the end face of the limiting plate 25 after being cleaned and is not easily exported centrally.

[0034] To solve the above problems, as Figure 2, 4 As shown in the figure, in the preferred embodiment provided by the present utility model based on the above-mentioned embodiment, a guiding channel 251 penetrating along its width direction is provided on the lower side wall of the limiting plate 25.

Among them, a guiding groove 221 penetrating along its width direction is provided on the upper side wall of the scraping plate 22, and the cross-section of the guiding groove 221 is the same as that of the guiding channel 251.

[0035] In this embodiment, by respectively providing the guiding groove 221 and the guiding channel 251 on the abutting side walls of the scraping plate 22 and the limiting plate 25, it is beneficial to lead out and collect the agglomerated gypsum from them, avoid a large amount of agglomerated gypsum accumulating on the scraping plate 22, increase the difficulty of cleaning and collection, avoid the excessive accumulated agglomerated gypsum re-adhering to the forming belt 30, and keep the forming belt 30 clean itself.

[0036] In the above-mentioned embodiment, the position of the scraping plate 22 relative to the limiting plate 25 is fixed, resulting in the fixed relative position between the fixedly provided guiding groove 221 and the guiding channel 251, which is not conducive to adaptively adjusting the passing property of the guiding path according to different forms of agglomerated gypsum.

[0037] To solve the above problems, please continue to refer to Figure 2 As shown in the figure, in the preferred embodiment provided by the present utility model based on the above-mentioned embodiment, the overlapping degree between the guiding channel 251 and the guiding groove 221 is adjustable; among them, the scraping plate 22 and the support plate 24 are connected by a telescopic shaft rod 27, and the telescopic adjustment of the telescopic shaft rod 27 can make the position of the scraping plate 22 stagger with that of the limiting plate 25 to change the overlapping degree between the guiding channel 251 and the guiding groove 221.

[0038] Based on the above-mentioned embodiment, a overlapping state of the guiding channel 251 and the guiding groove 221 is as shown in Figure 5 As shown in the figure, the guiding channel 251 and the guiding groove 221 correspond to each other to expand the passing area of the guiding channel 251.
