Description

Technical Field

[0001] The utility model relates to the technical field of liquid silicone foam production, and particularly to a screening device for liquid silicone foam raw materials. Background Technique

[0002] Foam is a material obtained by foaming plastic particles, abbreviated as foam. The types of foam include PU foam, anti-static foam, conductive foam, EPE, anti-static EPE, CR, EVA, cross-linked PE, SBR, EPDM, etc.

[0003] During the production process of foam, it is necessary to screen the raw materials for foam production, and select suitable raw materials for foam production. Among them, screening mainly uses a screening machine to screen the raw materials, and the qualified raw materials are selected for processing. However, when screening materials, when using a screening machine, the raw materials are placed inside the screening machine, and the raw materials are screened by the vibration of the screening machine. However, due to the accumulation of raw materials inside the screening box, it is necessary to vibrate multiple times to screen the raw materials inside the screening box, resulting in a problem of reduced screening efficiency. Summary of the Utility Model

[0004] In order to overcome the existing problems, the embodiment of the present application provides a screening device for liquid silicone foam raw materials. An adjustment component is provided above the screening component, which includes a limiting frame connected to the frame and a cross brace provided at the bottom end of the limiting frame. When the screening component vibrates during the screening of raw materials, on the one hand, the raw materials inside the screening component are screened under the vibration force, and on the other hand, the raw materials come into contact with the cross brace, turning the raw materials up and down, which can cooperate with the vibration to make the screening of raw materials faster and improve the screening effect.

[0005] The technical solution adopted by the embodiment of the present application to solve its technical problems is:

[0006] A screening device for liquid silicone foam raw materials includes a motor and a turntable provided at the output end of the motor. One end of the turntable is provided with a screening component for screening raw materials;

[0007] Wherein, a frame is provided at the bottom end of the screening component, and an adjustment component is provided on the outer surface of the frame. The adjustment component is located above the screening component and is used for mixing the raw materials inside the screening component. An adjustment component is provided above the screening component, which includes a limiting frame connected to the frame and a cross brace provided at the bottom end of the limiting frame. When the screening component vibrates during the screening of raw materials, on the one hand, the raw materials inside the screening component are screened under the vibration force, and on the other hand, the raw materials come into contact with the cross brace, turning the raw materials up and down, which can cooperate with the vibration to make the screening of raw materials faster and improve the screening effect.

[0009] Among them, a connecting seat is provided at one end of the screening box. A connecting rod is provided at one end of the connecting seat. The connecting rod is connected to the turntable. When the motor operates, it drives the turntable to rotate. When the turntable rotates, it drives the connecting rod to perform a circular motion. Under the circular motion of the connecting rod, it drives the screening box to move left and right on the upper surface of the pulley. In this way, the raw materials inside the screening box are screened by the sieve plate, and the screened raw materials fall on the surface of the blanking plate.

[0010] Preferably, four pulleys are provided on the top end of the frame on one side of the screening assembly. The four pulleys are fixedly connected to the frame by bolts. The four pulleys are connected to the frame, and the pulleys are slidably connected to the screening assembly. When the screening assembly is driven to move left and right by the connecting rod, at this time, the screening assembly slides on the upper surface of the pulley, and the friction with the screening assembly is reduced through the pulley.

[0011] Preferably, a workbench is provided at the bottom end of the motor. The motor is detachably installed on the workbench. The motor is electrically connected to the power supply. Under the operation of the motor, the workbench plays a supporting role for the motor.

[0012] Preferably, a blanking plate is provided at the bottom end of the frame. The blanking plate is fixedly connected to the frame. The blanking plate is of an inclined structure.

The connecting piece penetrates the limiting frame and installs the limiting frame on the surface wall of the frame, making the adjusting assembly fixed tightly.

[0014] Among them, several cross braces are provided on the lower surface of the limiting frame. The several cross braces are located inside the screening assembly. When the screening assembly slides left and right under the operation of the motor, at this time, the cross braces are concave inside the screening assembly. Under the left and right translation of the screening assembly, the cross braces mix and turn over the raw materials inside the screening assembly, so that the raw materials are mixed and turned over and then screened under the vibration of the screening assembly.

[0015] Preferably, a pin shaft is provided at the intersection of the connecting seat and the connecting rod. The connecting seat and the connecting rod are rotatable around the pin shaft. The connecting rod is connected to the connecting seat. When the motor operates, it drives the turntable to rotate. When the turntable rotates, it drives the connecting rod to move.
