Detailed Description
To explain technical contents, structural features, and objects and effects of the technical solutions in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.
Referring to fig. 2 to 5, it can be seen that:
the invention provides a cold-rolled steel sheet roll coater, which comprises support plates 8 which are symmetrically arranged, and a back roll 1, a coating roll 2, a feeding roll 3, a metering roll 4 and a homogenizing roll 5 of the roll coater which are sequentially arranged between the support plates 8, wherein a material storage disc 6 is arranged below the coating roll 2, the feeding roll 3, the metering roll 4 and the homogenizing roll 5. The back roll 1 of the coating machine runs anticlockwise and plays a role in supporting and steering the cold-rolled steel plate. The cold-rolled steel sheet is interposed between the coating roller 2 and the coater, and is coated by the coating roller 2 with the operation of the coater back roller 1. The feed roll 3 is used to transfer the coating from the metering roll 4 to the application roll 2. The metering roll 4 controls the thickness of the wet coating film by adjusting the gap between the metering roll and the feeding roll 3. The levelling roll 5 serves to distribute the coating material evenly over the metering roll. The bottom surface of the storage tray 6 is an inclined surface, so that the paint overflowing or dropping from the equipment can be collected and recycled.
Specifically, the supporting plate 8 is further provided with a controller 10, the back roll 1, the coating roll 2, the feed roll 3, the metering roll 4 and the material homogenizing roll 5 of the coating machine are respectively connected with respective driving devices, the controller 10 is respectively connected with the driving devices, and the running speed of each driving device is controlled through a program in the controller 10, so that the running speed of each rolling roll reaches a certain proportion, namely the surface speed of each roll is the same.
Specifically, the metering roll 4 with the top of the material homogenizing roll 5 is equipped with feedway 7, feedway 7 includes material loading conveyor 71 and the blown down tank 72 of the rectangular form V font structure of being connected with material loading conveyor 71, blown down tank 72 passes through the fixed block 73 to be fixed in backup pad 8 inboard, two symmetries of fixed block 73 set up and form V font contained angle, cooperate with the blown down tank 72 of V font, and such fixed mode is more convenient when blown down tank 72 installation is fixed.
In this embodiment, a material distributing device 74 is disposed inside the discharging chute 72, and when feeding, the material feeding device 71 feeds the coating material into the discharging chute 72 through a pipeline, and then distributes the coating material to two ends of the discharging chute 72 through the material distributing device 74 in the discharging chute 72, where the material distributing device 74 specifically includes: the receiving tray 75 with establish the material distribution channel 76 on the receiving tray 75, material distribution channel 76 is equipped with oval-shaped branch and detains 77, material distribution tray 75 establishes in the centre of tripper for connect the coating that the material pipe carried, in order to prevent that coating from overflowing, strike and cause the problem that the coating is many, pressure is big in the middle of the blown down tank 72, be semi-circular with material distribution tray 75's shape, wherein semi-circular is connected with material distribution channel 76, material distribution channel 76's bottom is lower than material distribution tray 75's bottom, firstly increases the flow of coating, secondly carries out the secondary speed reduction to coating through material distribution tray 75, makes its influence of feeding shock wave reduce when dividing the material, makes the branch material more steady and even, and then improves the effect of coating, improves product quality.
Specifically, a supporting plate 9 is arranged between the two supporting plates, and a sliding rail 91 is arranged on the supporting plate 9.
