Description

Technical Field

[0001] The utility model belongs to the technical field of screening machines, and in particular relates to a refractory plastic processing screening machine which is easy to clean. Background Art

[0002] Refractory plastics are made of refractory aggregates and powders, raw clay, chemical composite binders and admixtures. After being formulated, mixed, extruded into brick shapes, packaged and stored for a certain period of time, they still have good plasticity and can be constructed by tamping methods. Refractory clay is one of the necessary raw materials for the production of refractory plastics. During the production and processing of refractory plastics, the refractory clay needs to be screened, and a special screening machine is needed at this time.

[0003] After a long period of use, the sieve plate of the screening machine needs to be regularly replaced and cleaned. In order to ensure stability, the existing sieve plate is mostly fixed by bolt connection. However, this connection method is not convenient during disassembly and assembly. Not only does it require the use of external auxiliary tools, but it also requires repeated tightening and loosening of the bolts, which brings trouble to the personnel. Therefore, it is necessary to design a new screening machine to solve this problem. Utility Model Content

[0004] The purpose of the utility model is to provide a refractory plastic processing screening machine which is easy to clean, so as to solve the problem of inconvenience in disassembling and cleaning the internal sieve plate of the existing screening machine mentioned in the background art.

[0005] The cam is fixed on the frame, and the cam is connected with the cam on the frame by the sliding sleeve.

[0006] Preferably, the side of the docking protrusion facing the rear end of the sieve tray is an inclined surface and is adapted to the rear end of the sieve tray.

[0007] Preferably, a rubber pad is provided on the inclined surface of the docking protrusion, and the rubber pad is in contact with the rear end of the sieve plate.

[0008] Preferably, the supporting plate is in an L-shaped structure, a limiting locking ball is fixed on the surface of the supporting plate, and a corresponding spherical locking groove is provided on the upper wall of the movable groove.

[0009] Preferably, a vibration motor is provided at the bottom of the base, and the vibration motor is connected to the bottom end of the screen frame.

[0010] Preferably, a guard assembly is provided between the base and both sides of the screen frame, and the guard assembly includes side panels fixed to both ends of the top of the base, a fixed sleeve fixed to one side of the side panel, a telescopic rod telescopically connected to the fixed sleeve, a fixed plate fixed to the end of the telescopic rod, a fixed sleeve fixed to one side of the fixed plate, and a rubber ball rollingly arranged inside the fixed sleeve, and the rubber ball is in contact with both sides of the screen frame.

[0011] Preferably, the shielding assembly further comprises a spring, which is sleeved on the outer surface of the telescopic rod, and has two ends respectively abutting against the fixing sleeve and the fixing plate.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] Through the designed slide bar and slide groove, a sliding connection between the sieve plate and the sieve frame can be achieved. The clamping of the card plate and the card groove and the reinforcement with the help of the threaded knob can ensure the stable installation of the sieve plate. When disassembling, just loosen the threaded knob, and then move the support plate to push the card plate to release the clamping connection between the card plate and the card groove, and then the sieve plate can be pulled out for disassembly and cleaning. Under this design, there is no need for auxiliary tools during disassembly and assembly, and the disassembly and assembly steps are quick and simple, which provides convenience for personnel.
