Rubber ring flash separator

Abstract

The utility model belongs to the technical field of rubber ring processing, and particularly relates to a rubber ring flash separator which comprises supporting legs, the tops of the four supporting legs are respectively and fixedly provided with a separation box, and a centrifugal rotating mechanism and a reciprocating air pressure separation mechanism are respectively arranged in the separation box. According to the rubber ring flash separator, a rubber ring is placed in a specially-made centrifugal rotating barrel, and then the centrifugal rotating barrel is started to rotate at a high speed. The rubber ring can be tightly attached to the inner wall of the centrifugal rotating barrel under the action of centrifugal force, and meanwhile, the flash can be subjected to the action of larger centrifugal force due to the fact that the flash is thin and fragile; during centrifugal rotation, high-speed airflow is jetted to the rotating rubber ring, and the airflow impacts the flash part. Due to the fact that the flash is in a fragile state under the action of centrifugal force, the flash can be blown away from the rubber ring body more easily under the impact of high-speed airflow. And the flash can be effectively separated, and the rubber ring cannot be damaged.

Description

Technical Field

[0001] The utility model relates to the technical field of rubber ring processing, in particular to a rubber ring flash separator. Background Art

[0002] When producing rubber rings, especially rubber O-rings, they need to be molded and vulcanized in a mold under a certain pressure. To prevent lack of rubber, the rubber material filled in the mold cavity is appropriately kept with a certain interference amount. The excessive rubber material overflows from the mold cavity and forms flash. Rubber O-rings must be trimmed to obtain products with good appearance. The common flash removal methods for O-shaped rubber rings are manual trimming, cryogenic trimming, and water grinding trimming. Currently, manual trimming is still a commonly used method. The operator needs to hold a tool and gradually trim the flash along the outer edge of the product. The efficiency is low and the quality is difficult to guarantee. For small-sized rubber O-rings, it is difficult to trim thoroughly and cleanly, and it is easy to damage the product body. At the same time, it will also increase the risk of the tool scratching the finger. In addition, there is also the problem of "sticking the tool" in removing the flash by the tool. Therefore, a rubber ring flash separator is needed. Content of the Utility Model

[0003] Based on the existing technical problems, the utility model provides a rubber ring flash separator.

[0004] A rubber ring flash separator provided by the utility model includes support legs. At the top of each of the four support legs, a separation box is fixedly installed. Inside the separation box, a centrifugal rotation mechanism and a reciprocating pneumatic separation mechanism are respectively arranged. The centrifugal rotation mechanism realizes the action of rotating and centrifuging the rubber rings inside the separation box.

[0005] The reciprocating pneumatic separation mechanism realizes the action of separating the flash of the rubber rings inside the separation box.

[0006] Preferably, the centrifugal rotation mechanism includes a centrifugal rotation barrel. At the top of the separation box, a feeding funnel is installed. The inner wall of the feeding funnel is conical, and the bottom end of the feeding funnel corresponds to the top end of the centrifugal rotation barrel. An air inlet and separation hole is annularly arranged on the arc surface of the centrifugal rotation barrel.

[0007] Preferably, a rotation motor is fixedly installed at the bottom of the separation box. The output end of the rotation motor is fixedly installed with a rotation shaft through a coupling, and the top of the rotation shaft is fixedly installed with the bottom of the centrifugal rotation barrel.

[0008] Preferably, a discharge slot is also opened at the bottom of the separation box. A discharge slot is opened at the bottom of the centrifugal rotation barrel, and a sealing door is hingedly installed on the inner wall of the discharge slot.

[0009] Preferably, the reciprocating pneumatic separation mechanism includes bearing seats. The two bearing seats are arranged vertically and distributed up and down. The opposite surfaces of the two bearing seats are both rotatably connected with drive shafts through bearings. A drive motor is installed on the top of one of the bearing seats, and the output shaft of the drive motor is fixedly installed with the top of the drive shaft through a coupling.

[0010] Preferably, a sliding seat is threadedly connected to the surface of the drive shaft. One side surface of the sliding seat is slidably inserted into the inner wall of the separation box, and a connecting air pipe is fixedly installed on the other side surface of the sliding seat.

[0011] Preferably, air nozzles are installed on the surface of the connecting air pipe. The multiple air nozzles are linearly arrayed in the vertical direction of the connecting air pipe. The bottom end of the connecting air pipe is fixedly installed with a flexible air pipe. One end of the flexible air pipe penetrates and extends to the outer surface of the separation box. A bottom plate is fixedly installed at the bottom of one side of the separation box, and an air compressor is fixedly installed on the top of the bottom plate. The air outlet end of the air compressor is fixedly installed with the opposite end of the flexible air pipe.

[0012] The beneficial effects of the present utility model are as follows:

[0013] By setting the centrifugal rotation mechanism and the reciprocating pneumatic separation mechanism, the rubber ring is placed in a special centrifugal rotating barrel, and then the centrifugal rotating barrel is started to rotate at a high speed. The action of centrifugal force will make the rubber ring tightly adhere to the inner wall of the centrifugal rotating barrel. At the same time, due to the thin and fragile flash, it will be subjected to a greater centrifugal force. While centrifugally rotating, by spraying high-speed air flow onto the rotating rubber ring, the air flow will impact the flash part. Since the flash is already in a relatively fragile state under the action of centrifugal force, the impact of the high-speed air flow is more likely to blow it off from the rubber ring body; it can effectively separate the flash without damaging the rubber ring.

Specific embodiments

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0019] Refer to Figures 1 - 3 , a rubber ring flash separator, including a support leg 1, a separation box 2 is fixedly installed at the top of each of the four support legs 1, and a centrifugal rotation mechanism 3 and a reciprocating pneumatic separation mechanism 4 are respectively arranged inside the separation box 2.

[0020] In order to realize the rotation and centrifugation of the rubber ring inside the separation box 2; a centrifugal rotation mechanism 3 is provided, including a centrifugal rotation barrel 31. A feed hopper 32 is installed at the top of the separation box 2. The inner wall of the feed hopper 32 is conical, and the bottom end of the feed hopper 32 corresponds to the top end of the centrifugal rotation barrel 31. Intake separation holes 33 are annularly arranged on the arc surface of the centrifugal rotation barrel 31.

[0021] Specifically implemented in this way, the design of the intake separation holes 33 allows the airflow generated by the reciprocating pneumatic separation mechanism 4 to directly act on the rubber ring, helping the flash of the rubber ring to be more effectively separated while rotating centrifugally. The airflow can assist in separating the rubber ring from the flash, improving the overall separation efficiency.

[0022] A rotation motor 34 is fixedly installed at the bottom of the separation box 2. The output end of the rotation motor 34 is fixedly installed with a rotation shaft 35 through a coupling. The top of the rotation shaft 35 is fixedly installed with the bottom of the centrifugal rotation barrel 31.

[0023] Specifically implemented in this way, the rotation motor 34 directly drives the centrifugal rotation barrel 31 through the coupling and the rotation shaft 35. This direct drive method can reduce transmission losses and improve energy conversion efficiency; since the rotation shaft 35 is fixedly installed at the bottom of the centrifugal rotation barrel 31, it can ensure that the centrifugal rotation barrel 31 maintains a stable rotation speed during rotation, reduce vibration, and improve separation accuracy.

[0024] A discharge chute 36 is also opened at the bottom of the separation box 2. A discharge trough 37 is opened at the bottom of the centrifugal rotation barrel 31. A sealing door 38 is hingedly installed on the inner wall of the discharge trough 37.

[0025] Specifically, the discharge chute 37 is designed such that during the centrifugal rotation process, the separated flash materials can be automatically discharged from the centrifugal rotating barrel 31, improving the degree of production automation; the presence of the sealing door 38 can close the discharge chute 37 when discharging is not required, preventing the separated flash materials from mixing with the unseparated rubber ring materials and ensuring the separation effect.

[0026] In order to realize the action of separating the rubber ring flash inside the separation box 2; a reciprocating pneumatic separation mechanism 4 is provided, which includes bearing seats 41. The two bearing seats 41 are arranged vertically and distributed up and down. The opposite surfaces of the two bearing seats 41 are rotatably connected to a driving shaft 42 through bearings. A driving motor 43 is installed on the top of one of the bearing seats 41, and the output shaft of the driving motor 43 is fixedly installed with the top of the driving shaft 42 through a coupling.

[0027] Specifically, the use of the driving motor 43 can provide continuous and stable power, enabling the reciprocating pneumatic separation mechanism 4 to efficiently complete the separation work of the rubber ring flash.

[0028] A sliding seat 44 is threadedly connected to the surface of the driving shaft 42. One side surface of the sliding seat 44 is slidably inserted into the inner wall of the separation box 2, and a communicating air pipe 45 is fixedly installed on the other side surface of the sliding seat 44.

[0029] Specifically, the sliding insertion of the sliding seat 44 into the inner wall of the separation box 2 provides a guiding track for the driving shaft 42, ensuring the precise positioning of the driving shaft 42 during the reciprocating motion and improving the accuracy of the separation operation; the fixed installation of the communicating air pipe 45 enables the air pressure to be effectively transmitted to the sliding seat 44, and then transmitted to the parts that require the action of air pressure through the driving shaft 42 to realize the air pressure separation function; the communicating air pipe 45 on the sliding seat 44 can ensure the uniform distribution of the air pressure along the entire length of the driving shaft 42, making the separation of the rubber ring flash more uniform and effective.

[0030] Air nozzles 46 are installed on the surface of the communicating air pipe 45. A plurality of air nozzles 46 are linearly arrayed in the vertical direction of the communicating air pipe 45. The bottom end of the communicating air pipe 45 is fixedly installed with a flexible air pipe 47. One end of the flexible air pipe 47 penetrates and extends to the outer surface of the separation box 2. A bottom plate 48 is fixedly installed at the bottom of one side of the separation box 2, and an air compressor 49 is fixedly installed on the top of the bottom plate 48. The air outlet end of the air compressor 49 is fixedly installed with the opposite end of the flexible air pipe 47.

[0031] Specifically, the air nozzles 46 are linearly arrayed in the vertical direction on the connecting air pipe 45, which can ensure uniform distribution of air pressure during the separation process of the rubber ring, improving the separation effect; the use of the flexible air pipe 47 provides good flexibility, enabling the air pressure to be transmitted to different positions flexibly to adapt to different working scenarios; the air compressor 49 directly provides air pressure for the air nozzles 46 in the separation box 2, reducing air pressure loss and improving energy utilization efficiency.

[0032] By setting the centrifugal rotation mechanism 3 and the reciprocating air pressure separation mechanism 4, the rubber ring is placed in a specially designed centrifugal rotating barrel 31, and then the centrifugal rotating barrel 31 is started to rotate at a high speed. Under the action of centrifugal force, the rubber ring will adhere tightly to the inner wall of the centrifugal rotating barrel 31. At the same time, due to the thinner and more fragile flash, it will be subjected to a greater centrifugal force; while the centrifugal rotation is in progress, high-speed air flow is sprayed onto the rotating rubber ring, and the air flow will impact the flash part. Since the flash is already in a relatively fragile state under the action of centrifugal force, the impact of the high-speed air flow is more likely to blow it off from the main body of the rubber ring; achieving the effect of effectively separating the flash without damaging the rubber ring.

[0033] Working principle: During operation, the operator takes the processed rubber ring and places it inside the centrifugal rotating barrel 31. The rotating motor 34 works to drive the centrifugal rotating barrel 31 to rotate at a high speed, thereby controlling the rubber ring inside to adhere to the inner wall of the barrel under centrifugal force. At the same time, the driving motor 43 and the air compressor 49 are started to work. The air compressor 49 works to control multiple air nozzles 46 to spray high-speed air flow and blow air towards the air inlet separation hole 33. At the same time, the driving motor 43 rotates forward and backward to drive multiple air nozzles 46 to reciprocate in the vertical direction, enabling the separation operation of the flash of the rubber ring inside the centrifugal rotating barrel 31. The separated flash is discharged from the bottom discharge slot 36. When the separation is completed, the bottom sealing door 38 is opened, and the separated rubber ring is taken out.

[0034] As described above, only the preferred specific implementation manners of the present invention are provided, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
