Technical Field
[0001] This utility model relates to the field of steel ball polishing technology, specifically to a non-collision structure for the feed port based on bearing steel ball polishing. Background Technology
[0002] To improve the surface quality of bearing steel balls, mechanical means are usually used to reduce surface roughness, giving the bearing steel balls a smooth and bright appearance. For reference, see the relevant patent CN216830276U. Its essence is to set up a device tank and a rotating device to increase the stirring range inside the device tank, so as to avoid uneven polishing of the steel balls around the stirring center, thereby ensuring the polishing effect of the steel balls.
[0003] The following explanation focuses on the collection method of polished bearing steel balls: The surface of the polished steel balls has reached a high precision finish. If they are dropped at high speed or collide with each other, they are prone to micro-damage such as scratches and dents. While fully realizing the rapid collection of steel balls, it is also necessary to consider the impact of falling impact force or high-speed expansion between steel balls on the quality of the steel balls. To this end, we provide a discharge port anti-collision structure based on polished bearing steel balls to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a non-collision structure for the feed port based on polishing of bearing steel balls, so as to solve the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: The anti-collision structure of the discharge port based on polishing bearing steel balls includes a bracket, the side of which is provided with a discharge unit to slow down the rolling speed of the steel balls, and the top surface of the discharge unit is provided with a collection unit to reduce the impact force of the falling steel balls. The discharge unit includes a collection bin, a buffer funnel disposed inside the collection bin for collecting steel balls, and a discharge pipe fixedly connected to the bottom of the collection bin for conveying steel balls. The collection unit includes an outer shell fixedly installed on the top surface of the collection chamber, a fan fixedly installed on the side of the outer shell for providing airflow, and a support plate fixedly installed inside the outer shell for buffering.
[0006] A further improvement of the present invention is that: a gas supply pipe is fixedly connected to the side of the outer shell, the gas supply pipe is fixedly connected to the output end of the fan, and two gas distribution pipes are fixedly connected to the output end of the gas supply pipe.
[0007] A further improvement of this utility model is that: the support plates are arranged alternately inside the collection chamber, a tripod is fixedly connected to the bottom surface of the support plate, and an air inlet is fixedly connected to the side surface of the support plate.
[0008] A further improvement of this utility model is that: the air inlet is fixedly connected to the output end of the air distribution pipe, the air jet is fixedly connected to the inner bottom surface of the support plate, and a rubber pad is fixedly connected to the top surface of the support plate.
[0009] A further improvement of this utility model is that: an arc-shaped plate is fixedly connected to one end of the inside of the collection chamber, the arc-shaped plate is fixedly connected to the output end of the outer shell, and the arc-shaped plate is connected to the buffer funnel.
[0010] A further improvement of this utility model is that: a buffer nozzle is fixedly connected inside the top surface of the discharge pipe, a buffer air pipe is fixedly connected to the top surface of the buffer nozzle, and the buffer air pipe is fixedly connected to the bottom output end of the air conveying pipe.
[0011] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: 1. This utility model provides a material discharge port anti-collision structure based on bearing steel ball polishing. The material falls into the inside of the shell and then falls onto the top surface of the rubber pad. It slides down the slope of the rubber pad to the top surface of another rubber pad. Through the buffering effect of multiple rubber pads, the damage caused by the falling steel ball is reduced. The fan generates airflow and delivers it to three directions through the air supply pipe. The airflow is then transmitted to the interior of the support plate through the air distribution pipe and ejected from the interior of multiple air jets. By generating airflow on the bottom surface of the rubber pad, the impact force of the steel ball falling onto the top surface of the rubber pad is reduced, further protecting the steel ball.
[0012] 2. This utility model provides a discharge port anti-collision structure based on bearing steel ball polishing. The steel ball falls from the top surface of the collection bin onto the top surface of the arc plate. It slides relatively smoothly into the interior of the buffer funnel through the surface curvature of the arc plate. Guided by the buffer funnel, the steel ball is collected into the interior of the discharge pipe. When the steel ball is located on the side of the buffer nozzle, the airflow transmitted through the buffer air pipe will slow down the rolling speed of the steel ball, making it easier to collect the steel ball later.

[0015] The present invention will be further described in detail below with reference to embodiments: Example 1: As Figure 1-5 As shown, this utility model provides a discharge port anti-collision structure based on bearing steel ball polishing, including a bracket 1. The side of the bracket 1 is provided with a discharge unit 2 for slowing down the rolling speed of the steel ball. The top surface of the discharge unit 2 is provided with a collection unit 3 for slowing down the impact of the falling steel ball. The collection unit 3 includes a shell 31 fixedly installed on the top surface of the collection chamber 21, a fan 34 fixedly installed on the side of the shell 31 for providing air power, and a bearing plate 35 fixedly installed inside the shell 31 for buffering. An air supply pipe 33 is fixedly connected to the side of the shell 31. The air supply pipe 33 is fixedly connected to the output end of the fan 34. Two air distribution pipes 32 are fixedly connected to the output end of the air supply pipe 33. The blower 34 is fixed to the side of the housing 31, and the air distribution pipes 32 are fixed on both sides of the air supply pipe 33. The bottom surface of the blower is provided with an additional air outlet for transmitting airflow to the inside of the discharge unit 2. The support plates 35 are staggered inside the collection chamber 21. A tripod 39 is fixedly connected to the bottom surface of the support plate 35. An air inlet 36 is fixedly connected to the side of the support plate 35. The air inlet 36 is fixedly connected to the output end of the air distribution pipe 32. A jet nozzle 37 is fixedly connected to the bottom surface inside the support plate 35. A rubber pad 38 is fixedly connected to the top surface of the support plate 35. There are four support plates 35, which are fixed in pairs on the left and right sides of the outer shell 31, and the two pairs are staggered. The distance between each support plate 35 is equal, and a certain gap is reserved between the rubber pad 38 and the air nozzle 37.
[0016] In this embodiment, the material falls into the interior of the outer shell 31, then further falls onto the top surface of the rubber pad 38, and slides down the slope of the rubber pad 38 to the top surface of another rubber pad 38. Through the successive buffering of multiple rubber pads 38, the damage caused by the falling steel ball is reduced. The fan 34 generates airflow and delivers it to three directions through the air supply pipe 33. The airflow is transmitted to the interior of the support plate 35 through the air distribution pipe 32 and ejected from the interior of multiple air jets 37. By generating airflow on the bottom surface of the rubber pad 38, the impact force of the steel ball falling onto the top surface of the rubber pad 38 is reduced, further protecting the steel ball.
[0017] Example 2: As Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the discharge unit 2 includes a collection bin 21, a buffer funnel 23 disposed inside the collection bin 21 for collecting steel balls, and a discharge pipe 24 fixedly connected to the bottom surface of the collection bin 21 for transmitting steel balls. An arc-shaped plate 22 is fixedly connected to one end of the inside of the collection bin 21. The arc-shaped plate 22 is fixedly connected to the output end of the outer shell 31. The arc-shaped plate 22 is connected to the buffer funnel 23. A buffer nozzle 25 is fixedly connected inside the top surface of the discharge pipe 24. A buffer air pipe 26 is fixedly connected to the top surface of the buffer nozzle 25. The buffer air pipe 26 is fixedly connected to the bottom output end of the air conveying pipe 33. The arc plate 22 is fixed to the bottom output end of the outer shell 31, and the top opening of the arc plate 22 is adapted to the output end of the outer shell 31. The internal curvature of the buffer funnel 23 is relatively gentle. The buffer air pipe 26 can be connected to the air supply pipe 33 to transmit a part of the air flow inside the air supply pipe 33 to the inside of the buffer nozzle 25, and then transmit the air flow to the inside of the discharge pipe 24 through the buffer nozzle 25.
[0018] In this embodiment, the steel ball falls from the top surface of the collection chamber 21 onto the top surface of the arc plate 22. It then slides relatively smoothly into the interior of the buffer funnel 23 through the relatively gentle curvature of the surface of the arc plate 22. Guided by the buffer funnel 23, the steel ball is collected into the interior of the discharge pipe 24. When the steel ball is located on the side of the buffer nozzle 25, the airflow transmitted through the buffer air pipe 26 will slow down the rolling speed of the steel ball, making it easier to collect the steel ball later.
[0019] The working principle of the anti-collision structure of the feed port based on bearing steel ball polishing is explained in detail below.
[0020] like Figure 1-5 As shown, the material is collected by the collection unit 3, and the falling speed of the material is buffered. The airflow drives the rubber pad 38 to suspend it, further buffering the material. The discharge unit 2 will discharge the material that has fallen into it in an orderly manner, which is convenient for subsequent collection of the material. The material falls into the interior of the outer casing 31, and further falls onto the top surface of the rubber pad 38. It then slides down the slope of the rubber pad 38 to the top surface of another rubber pad 38. Through the successive buffering of multiple rubber pads 38, the damage caused by the falling steel ball is reduced. The fan 34 generates airflow and delivers the airflow to three directions through the air supply pipe 33. The airflow is transmitted to the interior of the bearing plate 35 through the air distribution pipe 32 and ejected from the interior of multiple jet nozzles 37. By generating airflow on the bottom surface of the rubber pad 38, the impact force of the steel ball falling onto the top surface of the rubber pad 38 is reduced, further protecting the steel ball. The steel ball falls from the top surface of the collection chamber 21 onto the top surface of the arc plate 22. It slides relatively smoothly through the surface curvature of the arc plate 22 into the interior of the buffer funnel 23. Guided by the buffer funnel 23, the steel ball is collected into the interior of the discharge pipe 24. When the steel ball is located on the side of the buffer nozzle 25, the airflow transmitted through the buffer air pipe 26 will slow down the rolling speed of the steel ball, making it easier to collect the steel ball later.
[0021] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all modifications or improvements made without departing from the spirit and concept of the present invention are within the protection scope of the present invention.
