The utility model provides a pair of receiving device is used in screening of steel ball stub bar can carry out the secondary screening to the steel ball, avoids sneaking into big steel ball.
Description
Technical Field
The utility model relates to a steel ball production facility, especially a receiving device is used in screening of steel ball stub bar.
Background
Unqualified stub bar can be produced to the steel ball in cold heading machine-shaping in-process, and these stub bars are the ball that hinders of taking the breach, and unformed cylinder need reject through stub bar sieving mechanism.
The existing stub bar screening device adopts a screen cylinder to screen and then directly receives materials through a material receiving box, such as a rotary screening machine in the patent with the application number of '201820554592.5'. However, because the steel balls also contain larger steel balls, only smaller stub bars can be screened out through the screen drum, and the screening drum cannot be completely cleaned.
Disclosure of Invention
The utility model aims to solve the technical problem that a receiving device is used in steel ball stub bar screening is provided, can carry out the secondary screening after the stub bar screening and connect the material, conveniently rejects the major part steel ball.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is:
a receiving device for screening steel ball stub bars comprises a support frame, wherein one side of the support frame is rotatably connected with a shell of a screening device through a bearing, the support frames at the left end and the right end of the bearing are respectively fixed with a spring and a roller, the other end of the spring is connected with the shell, and the roller is extruded by a scraper on a screen drum to move up and down; the support frame is provided with a screen frame, and a material collecting box is arranged below the screen frame.
And a limiting plate is fixed on the shell below the supporting frame.
The scraper blade is an arc-shaped plate.
The utility model relates to a receiving device is used in screening of steel ball stub bar has following technological effect:
1) the screen frame is placed in the support frame, and the support frame vibrates repeatedly under the action of the scraper of the screen cylinder, so that the steel balls in the screen frame are vibrated quickly and fall down, and screen holes are prevented from being blocked.
2) The arc-shaped scraper plate and the rotatable roller are adopted for cooperation, so that friction can be reduced, and the vibration operation is guaranteed to be reliable and effective for a long time.
3) The power is not required to be provided from the outside, the reliability and the effectiveness are realized, and the cost is saved.
Drawings
The invention will be further explained with reference to the following figures and examples:
fig. 1 is a schematic structural diagram of a screening apparatus.
Fig. 2 is a schematic structural diagram of the present invention.
Fig. 3 is a schematic structural diagram of the present invention.
Fig. 4 is a schematic view of the working state of the present invention.
Fig. 5 is a top view of the center frame of the present invention.
In the figure: the screen frame comprises a supporting frame 1, a shell 2, a spring 3, a roller 4, a screen drum 5, a scraper 6, a screen frame 7, a material collecting box 8 and a limiting plate 9.
Detailed Description
As shown in figure 1, the receiving device for screening the steel ball stub bar comprises a support frame 1, wherein the support frame 1 is of a square or rectangular frame structure and is provided with an upper opening and a lower opening. The bearing is arranged in the middle of one side of the support frame 1 and is rotatably connected with the short shaft on the shell 2 of the screening device, so that the support frame 1 can swing left and right. And the support frame 1 is provided with a hanging ring at the right side of the bearing, one end of the spring 3 is hung on the hanging ring, and the other end is hung on the shell 2 of the screening device in an inclined and downward manner. And the idler wheels are arranged on the left side of the bearing of the support frame 1, the scraper 6 is arranged on the screen drum 5 of the corresponding screening device, and when the screen drum 5 rotates, the scraper 6 also rotates along with the screen drum. Through setting up the relative position of scraper blade 6, gyro wheel 4, can make scraper blade 6 rotate in-process and push down gyro wheel 4 to make support frame 1 swing around the bearing. After the scraper 6 is separated from the roller 4, the supporting frame 1 automatically resets under the action of the spring 3.
A screen frame 7 is placed in the support frame 1, screen holes are fully distributed in the screen frame 7, normal steel balls can pass through the screen holes and fall into a material collecting box 8 below the screen holes, and larger steel balls are retained in the screen frame 7 to play a role in secondary screening.
As the screen drum 5 rotates once, the scraper 6 extrudes the roller 4, so that the support frame 1 swings once, steel balls falling into the screen frame 7 can be rapidly screened, and certain steel balls are prevented from being blocked on screen holes.
A limiting plate 9 is fixed on the shell 2 below the supporting frame 1. The limit plate 9 can effectively limit the swing amplitude of the support frame 1 and prevent the steel ball from popping up.
The scraper 6 is an arc-shaped plate. Thereby reducing friction with the roller 4.
The working principle and the process are as follows: as shown in fig. 4, when the screen drum 5 is driven by the motor to rotate clockwise, the scraper 6 rotates via the roller 4 and presses down the roller 4, the support frame 1 rotates counterclockwise around the bearing, and when the scraper 6 is separated from the roller 4, the support frame 1 is reset rapidly under the action of the spring 3. Every time the screen drum 5 rotates a circle, the support frame 1 swings once, the screen frame 7 in the support frame 1 also swings together, so that normal steel balls in the screen frame 7 can be rapidly screened and fall down, and large steel balls are retained in the screen frame 7.
