Description

Technical Field

[0001] The utility model relates to the technical field of sealing ring processing, in particular to a vibration screening device for removing flash of a sealing ring. Background Technique

[0002] During the production of polytetrafluoroethylene (PTFE) sealing rings, due to the gaps in the mold, flash is generated during the production process. Before the product is shaped, the burrs must be removed. Currently, the burrs are manually removed with a blade by workers. Manual deburring has unstable quality, low production efficiency, high labor intensity, and high labor cost, which restricts the mass production of products.

[0003] As disclosed in a kind of ultrasonic flash removal device for a sealing ring in Chinese Patent CN217860689U, by using a machine instead of manual flash removal, it not only ensures flash removal but also does not damage the sealing ring, greatly saving the labor cost of production, improving production efficiency, and reducing the labor intensity of workers. The ultrasonic flash removal is carried out by combining ultrasonic waves with polishing abrasives and cleaning liquid. The ultrasonic generator emits high-frequency oscillation signals, and the ultrasonic transducer converts them into high-frequency mechanical oscillations and propagates into the water, causing the water to flow and generate tens of thousands of bubbles. When the bubbles rapidly increase and burst, shock waves are generated to continuously damage the connection between the sealing ring and the flash. The corrosiveness of the cleaning liquid will also corrode the connection between the sealing ring and the flash. Through the cooperation of ultrasonic waves and the cleaning liquid, the connection between the sealing ring and the flash becomes loose or even falls off. Combined with the continuous impact of the polishing abrasives that are constantly moving through the stirring rod in the bearing groove, and the design of several fan blades on the stirring rod, the stirring force of the stirring rod can be increased, thereby ensuring that all the flash of the sealing ring can be removed. The cooperation of the impact force of ultrasonic waves and the continuous impact of the polishing abrasives on the sealing ring also makes the periphery of the sealing ring with flash removed smoother. Through the discharge valve at the bottom of the bearing groove, the sealing ring and polishing abrasives after flash removal can be poured onto the vibrating screen. Through the vibrating screen, the sealing ring and polishing abrasives can be quickly separated, greatly improving production efficiency and reducing labor intensity.

[0004] However, during the use of this device, when screening the sealing ring and polishing abrasives through the vibrating screen, since the polishing abrasives and the sealing ring cover the surface of the vibrating screen relatively thickly, the screening quality is poor and the screening efficiency is low.

[0005] Therefore, we urgently need to provide a vibration screening device for removing flash of a sealing ring. Content of the Utility Model

[0006] The purpose of the present utility model is to provide a vibration screening device for removing flash from sealing rings, so as to solve the problems of poor screening quality and low screening efficiency caused by the fact that during the use process, when screening the sealing rings and polishing abrasives through a vibrating screen, the polishing abrasives and the sealing rings cover the surface of the vibrating screen relatively thickly.

[0026] Please refer to Figures 1 - 5 , the present invention provides a technical solution:

[0027] Embodiment 1:

[0028] A vibrating screening device for removing flash from a sealing ring includes a carrier frame 1, a reaction tank 2 and support legs 3. The reaction tank 2 is fixedly installed on the top of the carrier frame 1. A discharge port is fixedly installed at the bottom of the reaction tank 2, and the discharge port is connected to a solenoid valve. The opening and closing of the discharge port are controlled by the solenoid valve, so as to facilitate the discharge of the sealing ring and polishing abrasive inside the reaction tank 2. The support legs 3 are fixedly installed around the bottom of the carrier frame 1. A processing device is arranged inside the carrier frame 1, and the processing device includes a screening unit, a flash removal unit and a waste collection unit.

[0029] The screening unit is arranged at the bottom of the carrier frame 1, the flash removal unit is arranged inside the reaction tank 2, and the waste collection unit is arranged below the carrier frame 1.

[0030] The screening unit includes a vibrating screen 401, a vibrating motor 402, a fixing rod 403, a fixing plate 404, a rotating shaft 405, a first motor 406, a transmission member 407 and a baffle 408. The vibrating screen 401 is installed at the bottom of the carrier 1. The vibrating motor 402 is fixedly installed at the bottom of the vibrating screen 401. The fixing rods 403 are fixedly installed on the front and rear sides of the vibrating screen 401. One end of the fixing rod 403 away from the vibrating screen 401 is fixedly connected to one side of the fixing plate 404, and the fixing rod 403 near the first motor 406 is fixedly connected to the first motor 406. The stability of the rotation of the baffle 408 is improved through the fixing rod 403. The fixing plate 404 is fixedly installed on the front and rear sides of the inner wall of the vibrating screen 401. The rotating shaft 405 is rotatably connected to the adjacent sides of the front and rear fixing plates 404. The first motor 406 is fixedly installed on the front of the front fixing plate 404 and is fixedly connected to one end of the rotating shaft 405. The transmission member 407 is installed on the outer surfaces of the left and right rotating shafts 405. The transmission member 407 includes a pulley and a belt. The pulley is fixedly installed on the outer surfaces of the front ends of the left and right rotating shafts 405. The belt is sleeved on the outer sides of the left and right pulleys. The baffle 408 is fixedly installed on the outer surface of the rotating shaft 405. The baffle 408 is used to spread the relatively thickly piled-up sealing rings and polishing abrasives thinly, so as to facilitate the screening of the sealing rings and polishing abrasives.

[0031] The flash removal unit includes a feed inlet 501, a second motor 502, an output shaft 503, a stirring rod 504 and an ultrasonic generator 505. The feed inlet 501 is fixedly installed on the right side at the top of the reaction tank 2. The second motor 502 is fixedly installed at the center of the top of the reaction tank 2. One end of the output shaft 503 is fixedly installed at the output end of the second motor 502 and extends into the reaction tank 2. The stirring rod 504 is fixedly installed on the outer surface of the output shaft 503. The stirring rods 504 are evenly distributed on the outer surface of the output shaft 503. The sealing rings, polishing abrasives and cleaning liquid in the reaction tank 2 are mixed evenly through the stirring rod 504, so as to damage the connection between the sealing ring and the flash, and realize the flash removal of the sealing ring. The ultrasonic generator 505 is fixedly installed at the bottom inside the reaction tank 2. By emitting high-frequency oscillation signals through the ultrasonic generator 505, bubbles are generated when the water flows. During the continuous increase and rupture of the bubbles, the connection between the sealing ring and the flash is damaged.

[0032] Embodiment 2:

[0033] On the basis of Embodiment 1: The waste collection unit includes a collection box 601 and a handle 602. The collection box 601 is installed below the vibrating screen 401. The polishing abrasives are collected through the collection box 601. The handle 602 is fixedly installed on the left side of the collection box 601.

[0034] Embodiment 3:

[0035] On the basis of Embodiment 1: The vibrating screen 401 is tilted downward by 30°, facilitating the movement of the sealing ring and polishing abrasive on the vibrating screen 401 from right to left, so that the sieved sealing ring falls out of the left end of the vibrating screen 401 for collection.

[0036] During use, the sealing ring to be processed is put into the reaction tank 2 by the second motor 502, an appropriate amount of cleaning liquid is added, and then the second motor 502 is started to drive the output shaft 503 to rotate. When the output shaft 503 rotates, it drives the stirring rod 504 to rotate, enabling the corrosiveness of the cleaning liquid to corrode the connection between the sealing ring and the flash, so that the flash becomes loose or even falls off. At the same time, in cooperation with the ultrasonic generator 505 to emit high-frequency oscillation signals, bubbles are generated by the flowing water. During the continuous increase and rupture of the bubbles, the connection between the sealing ring and the burr is damaged, making the periphery of the sealing ring smoother. Then, the discharge port is opened, and the sealing ring and the polishing abrasive fall onto the surface of the vibrating screen 401. The vibrating motor 402 is started to vibrate the vibrating screen 401, causing the polishing abrasive to fall into the collection box 601 through the sieve holes opened on the vibrating screen 401 for collection. In cooperation with the first motor 406 to drive the rotating shaft 405 to rotate, when the rotating shaft 405 rotates, it drives two belt wheels to rotate through the belt, so that the left and right deflector plates 408 rotate, thinning the piled-up sealing ring and polishing abrasive, making it easier to screen the polishing abrasive and the sealing ring, with high screening efficiency and good screening quality.
