Abstract
Description
Technical Field
[0001] This utility model relates to the field of ceramicized silicone rubber production technology, and in particular to an inorganic powder screening mechanism for ceramicized silicone rubber production. Background Technology
[0002] The inorganic fillers added to ceramicized silicone rubber include ceramic powders such as alumina and silicon oxide. These fillers can improve the hardness, strength and wear resistance of silicone rubber, while also increasing the material's heat resistance and chemical resistance.
[0003] Before adding powder, it is necessary to sieve the powder first. Only fine, non-caking powder can meet the production needs. Existing inorganic powder sieving mechanisms are generally carried out by sieving machines such as vibrating screens. The screens of these sieving devices are relatively fixed to the fixed frame, which can easily cause the screen holes to become clogged. Furthermore, fine powder is affected by its own friction, charge, adsorption and other factors, making it difficult to sieve, which affects the powder screening effect and sieving speed. Utility Model Content
[0004] This utility model addresses the deficiencies in the prior art by providing an inorganic powder screening mechanism for the production of ceramicized silicone rubber.
[0005] This utility model is achieved through the following technical solution:
[0006] An inorganic powder sieving mechanism for the production of ceramicized silicone rubber includes a sieving tube, a mounting ring, a fixing ring, a clamping ring, a telescopic woven fabric, a filter screen, a control mechanism, a support rod, a guide tube, a motor base, a motor, and a protrusion. The mounting ring is fixedly installed inside the sieving tube, the fixing ring is welded and fixed inside the mounting ring, the clamping ring is installed at the top of the fixing ring, the telescopic woven fabric is sewn to both ends of the filter screen, the support rod is fixedly installed at the bottom of the fixing ring, the guide tube is fixedly installed at the end of the support rod, the control mechanism is engaged inside the guide tube, and the motor base is installed outside the guide tube. The motor is mounted at the bottom of the motor base, and the protrusion is sleeved and fixed to the output end of the motor. The control mechanism includes a lifting tube, a pressure plate, a cylinder, a connecting plate, a control rod, a plug, a contact ring, a pressure ring, and a spring. The pressure plate is fixedly installed inside the lifting tube, the cylinder is fixedly installed outside the lifting tube, the connecting plate is fixedly installed at the extension end of the cylinder, the control rod is fixedly installed at one end of the connecting plate, the plug is fixedly installed at the top of the control rod, the contact ring is fixedly installed inside the top of the lifting tube, the pressure ring is fixedly installed outside the top of the lifting tube, and the spring is fixedly installed at the bottom end of the pressure ring.
[0007] In a preferred embodiment of this utility model, a bearing ring is provided at the top of the guide tube, and the bottom end of the spring is fixed to the bearing ring at the top of the guide tube;
[0008] The motor drives the protrusion to rotate, which in turn applies pressure to the pressure plate, controlling the descent of the lifting tube. This compresses the spring and acts as a reset mechanism during the rotation of the protrusion, causing the filter cloth to shake.
[0009] In a preferred embodiment of this utility model, the plug has a frustum-shaped structure, and a rubber sealing ring is sleeved on its outer side, with the plug being engaged inside the contact ring;
[0010] During the screening process, the plug blocks the contact ring to prevent powder from falling. After screening is completed, the cylinder extends and moves the plug downward, thereby opening the top of the lifting pipe and discharging the waste material from the lifting pipe.
[0011] In a preferred embodiment of this utility model, one end of the filter mesh is telescopically woven and clamped between the fixing ring and the pressing ring, and is fixed by the fixing ring and the pressing ring; the other end of the telescopically woven and clamped is fixedly disposed at the top of the lifting tube.
[0012] Because the motor controls the up and down movement of the lifting tube, the elasticity of the fabric needs to be stretched, which causes the filter cloth to deform and bounce, making the powder jump, thus better achieving the effect of screening materials and preventing screen hole clogging.
[0013] In a preferred embodiment of this utility model, the outer side of the protrusion at the motor output end contacts the top of the pressure plate.
[0014] In a preferred embodiment of this utility model, a guide bar is vertically arranged on the outer side of the lifting tube, and a guide groove is provided on the inner side of the guide tube to cooperate with it, so as to ensure that the lifting tube moves vertically.
[0015] The beneficial effects of this utility model are:
[0016] This inorganic powder screening mechanism for the production of ceramicized silicone rubber controls the up-and-down movement of the lifting pipe, causing the telescopic fabric to deform and bounce, thus causing the powder entering the screening mechanism to rise and bounce. When the powder falls, it collides with the filter cloth, which not only ensures the screening effect but also causes the filter cloth to shake, thereby reducing the risk of screen clogging, effectively improving the powder screening rate, ensuring screening effect, reducing the risk of screen clogging, and reducing the frequency of daily maintenance.

The mounting ring 2 is fixedly installed inside the sieving tube 1, the fixing ring 3 is welded and fixed inside the mounting ring 2, the clamping ring 4 is installed on the top of the fixing ring 3, the telescopic woven fabric 5 is sewn to both ends of the filter screen 6, the support rod 8 is fixedly installed at the bottom of the fixing ring 3, the guide tube 9 is fixedly installed at the end of the support rod 8, the control mechanism 7 is engaged inside the guide tube 9, the motor base 10 is installed outside the guide tube 9, and the motor 11 is installed on the motor base 12. At the bottom, the protrusion 12 is sleeved and fixed to the output end of the motor 11. The control mechanism 7 includes a lifting tube 71, a pressure plate 72, a cylinder 73, a connecting plate 74, a control rod 75, a plug 76, a contact ring 77, a pressure ring 78, and a spring 79. The pressure plate 72 is fixedly installed inside the lifting tube 71, the cylinder 73 is fixedly installed outside the lifting tube 71, the connecting plate 74 is fixedly installed at the extension end of the cylinder 73, the control rod 75 is fixedly installed at one end of the connecting plate 74, the plug 76 is fixedly installed at the top of the control rod 75, the contact ring 77 is fixedly installed inside the top of the lifting tube 71, the pressure ring 78 is fixedly installed outside the top of the lifting tube 71, and the spring 79 is fixedly installed at the bottom end of the pressure ring 78.
[0024] Specifically, a bearing ring is provided at the top of the guide tube 9, the bottom end of the spring 79 is fixed to the bearing ring at the top of the guide tube 9, the plug 76 has a frustum-shaped structure, a rubber sealing ring is sleeved on its outer side, the plug 76 is locked inside the contact ring 77, one end of the filter cloth 6 is a telescopic fabric 5 locked between the fixing ring 3 and the pressing ring 4, and is clamped and fixed by the fixing ring 3 and the pressing ring 4, and the other end of the telescopic fabric 5 is fixedly set at the top of the lifting tube 71, the outer side of the protrusion 12 at the output end of the motor 11 contacts the top of the pressure plate 72, a guide strip is vertically provided on the outer side of the lifting tube 71, and a guide groove that matches it is opened on the inner side of the guide tube 9 to ensure that the lifting tube 71 moves vertically.
[0025] In this embodiment, the screening pipe 1 is connected to the entire screening equipment through flanges at its top and bottom. The entire screening operation is mainly carried out through the filter mesh 6, which has a funnel-shaped structure. The telescopic fabric 5 at its top is clamped and fixed by the clamping ring 4 and the fixing ring 3, and the telescopic fabric 5 at its bottom is fixed to the outer side of the top of the lifting pipe 71. When the equipment is in use, the cylinder 73 is in the contracted state. At this time, the plug 76 contacts the inner wall of the contact ring 77, blocking the top of the lifting pipe 71. The motor 11 starts and drives the protrusion 12 to rotate. The surface of the protrusion 12 contacts the surface of the pressure plate 72, causing the lifting pipe 71 to be pressed down. Since the surface of the lifting pipe 71 is vertically provided with guide strips, and the guide tube 9 is opened inside... The guide groove that works in conjunction with it, through the guide tube 9 fixed by the support rod 8, provides a limiting and guiding effect for the lifting tube 71. The lifting tube 71 can only move vertically inside the guide tube 9. At this time, the pressure ring 78 squeezes the spring 79, the lifting tube 71 descends, the telescopic fabric 5 is stretched and deformed, and as the protrusion 12 rotates, the spring 79 and the telescopic fabric 5 return to their original positions, thereby causing the lifting tube 71 to rise. As the lifting tube 71 moves up and down, the filter cloth 6 moves up and down and produces a certain deformation, so that the added inorganic powder collides with the filter cloth 6, causing it to be shaken and processed by the rapid sieving of powder by the filter cloth 6. The shaking and deformation of the filter cloth 6 effectively reduces the risk of clogging of its surface filter holes.
[0026] Furthermore, after the powder screening is completed, the cylinder 73 extends, and under the action of the connecting plate 74 at its end, the bottom control rod 75 of the plug 76 moves the plug 76 downward, thereby opening the top of the lifting pipe 71. Unqualified powder, granules and caking materials will be discharged from the bottom of the lifting pipe 71, achieving the effect of waste cleaning.
[0027] It should be noted that the parts not covered in this utility model are the same as or can be implemented using existing technology; the various drives in this utility model can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, and motors in conjunction with connecting rods, guide rods, etc., and are not limited to the structures described in the specification and the drawings.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
