The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention is mainly suitable for the gypsum board auxiliary material conveying stage, and the gypsum board auxiliary material is fine and smooth in powder quality and easy to fill and pile, so that the auxiliary material is poor in fluidity and easy to break, and the production quality of the gypsum board is influenced. The invention mainly monitors the blanking state of the storage bin by arranging the material breaking detection switch, and arranges the material loosening device and the air blowing filter cloth homogenizing structure in the storage bin, so that auxiliary materials can be blown and stirred in time when the material is broken, the fluidity of the auxiliary materials is improved, and the auxiliary materials can be blanked in time.
As shown in fig. 1 and 2, the invention provides a device for preventing gypsum board auxiliary material from being broken, which comprises a control device 4, a material breaking detection switch 1, a wind drum filter cloth homogenizing structure 2 and a material loosening device 3, wherein the material breaking detection switch 1 is arranged on a storage bin for conveying the auxiliary material, is used for monitoring the blanking state of the storage bin in real time, and sends a material breaking feedback signal to the control device 4 when the storage bin is in the material breaking state; the air-blast filter cloth homogenizing structure 2 is arranged in the storage bin and is used for blowing air into the storage bin; the material loosening device 3 is arranged in the storage bin and is used for stirring auxiliary materials in the storage bin; the material breaking detection switch 1, the air drum filter cloth homogenizing structure 2 and the driving motor of the material loosening device 3 are respectively electrically connected with the control device 4.
As shown in fig. 3, the adjusting process of the control device 4 controlling the action of the air drum filter cloth homogenizing structure 2 and the material loosening device 3 according to the feedback signal of the material breakage detecting switch 1 to prevent material breakage is summarized as follows: control device 4 receives disconnected material feedback signal, and carry control command to the driving motor of tripper 3, driving motor drive tripper 3 opens work and stirs the interior auxiliary material of feed bin, control device 4 carries regulation and control command to wind drum filter cloth homogenization structure 2 simultaneously, wind drum filter cloth homogenization structure 2 opens and blows the auxiliary material with loose feed bin to wind drum filter cloth homogenization structure 2 interior blast, it is gaseous to blow through wind drum filter cloth homogenization structure 2, make the interior auxiliary material of feed bin fluffy, and cooperate tripper 3 constantly to turn over the interior auxiliary material of stirring feed bin, improve the auxiliary material mobility, avoid leading to the auxiliary material clouding because of piling up, the disconnected material.
Because the auxiliary material is carried, especially the powder is carried, there may be the gap between the powder, if direct will expect absolutely that detection switch 1 is just to the feed bin discharge gate, the normal unloading of feed bin, it indicates that expect absolutely that detection switch 1 detects the auxiliary material (detection light is sheltered from), when the feed bin expects absolutely, expect absolutely that detection switch 1 then can not detect the auxiliary material (detection light can not be through the auxiliary material reflection), and when adopting this kind of mode, because there may be the gap between the powder, even the normal unloading of feed bin, expect that detection switch 1's monitoring signal also may be occasionally not, can appear detecting the inaccurate condition. Consequently this embodiment sets up the plate structure that supplies disconnected material detection switch 1 to detect usefulness bottom the feed bin to whether the feed bin is disconnected material is distinguished better, and can guarantee the unloading volume through the belt weigher accurately.
