Description

Technical Field

[0001] The utility model relates to the technical field of rubber powder production, in particular to an anti-blocking screening machine for rubber powder production. Background Art

[0002] Rubber powder refers to the powdered rubber material obtained by crushing waste rubber products.

[0003] In the production process, the rubber powder needs to be screened by a screening machine to prevent impurities in the rubber powder. However, during the screening process, the existing rubber powder screening machines usually directly put the rubber powder into the inside of the hopper, and the rubber powder falls into the screening machine through the hopper for screening. However, the rubber powder that falls into the screening machine through the hopper tends to accumulate together, which not only affects the screening effect of the screening machine, but also easily blocks the sieve holes of the sieve plate inside the screening machine, affecting the screening effect of the sieve plate.

[0008] A guide plate, one side of which is hinged to the top inner wall of the screening machine, and the other side of which is hinged with a connecting rod, and the end of the connecting rod away from the guide plate is hinged to the outer wall of the push rod. By setting the guide plate, the rubber powder discharged from the hopper into the screening machine can be evenly guided to both sides.

A discharge port 8 is provided, and the rubber powder is first poured into the interior of the hopper 6, so that the rubber powder is discharged into the interior of the screening machine 1 through the discharge port 8 and the feed port 7, and falls on the sieve plate 3. The interior of the screening machine 1 is provided with a material leveling mechanism 9 to prevent the rubber powder from clogging the sieve plate 3. By setting the material leveling mechanism 9, the falling rubber powder can be evenly dropped on the sieve plate 3, and the accumulation of the rubber powder on the sieve plate 3 can be avoided. An auxiliary mechanism 10 is provided on the hopper 6. By setting the auxiliary mechanism 10, the rubber powder can be delivered to the interior of the screening machine 1 in small quantities for multiple times, and the accumulation of too much rubber powder on the sieve plate 3 can be avoided.

[0026] The material leveling mechanism 9 comprises a push rod 91, a cylinder 92, a guide plate 93, a convex plate 94 and a connecting rod 95; the push rod 91 is slidably connected to the top inner wall of the screening machine 1, and the push rod 91 penetrates the screening machine 1, a convex plate 94 is fixedly installed on the side wall of the push rod 91, the cylinder 92 is fixedly installed on the top of the screening machine 1, the piston end of the cylinder 92 penetrates the screening machine 1 and is fixedly installed on the upper surface of the convex plate 94, the piston end of the cylinder 92 is slidably connected to the penetration of the screening machine 1, the cylinder 92 is repeatedly started, and the convex plate 94 can be used to The push rod 91 is driven to move reciprocatingly up and down. One side of the guide plate 93 is hinged to the top inner wall of the screening machine 1, and the other side of the guide plate 93 is hinged with a connecting rod 95. The reciprocating swing of the guide plate 93 can evenly guide the rubber powder discharged from the hopper 6 into the screening machine 1 to both sides, so that the falling rubber powder evenly falls on the screen plate 3. The end of the connecting rod 95 away from the guide plate 93 is hinged to the outer wall of the push rod 91. The push rod 91 can move reciprocatingly up and down in coordination with the connecting rod 95 to push and pull the guide plate 93, so that the guide plate 93 can swing reciprocatingly.

[0027] The auxiliary mechanism 10 comprises a cross bar 101, a rotating drum 102, a spiral groove 103 and a guide rod 104; one end of the cross bar 101 is fixedly mounted on the outer wall of the hopper 6, and the other end of the cross bar 101 is fixedly mounted with the rotating drum 102. When the rotating drum 102 rotates, it cooperates with the cross bar 101 to drive the hopper 6 to rotate synchronously back and forth. Through the reciprocating rotation of the hopper 6, in cooperation with the discharge port 8 and the feed port 7, rubber powder can be repeatedly and in small amounts delivered to the interior of the screening machine 1 to avoid excessive accumulation of rubber powder on the sieve plate 3. A spiral groove 103 is provided on the rotating drum 102, and a guide rod 104 is fixedly mounted on the side wall of the push rod 91. The outer wall of the guide rod 104 is attached to the inner wall of the spiral groove 103. When the push rod 91 reciprocates up and down, it will drive the guide rod 104 to fit the inner wall of the spiral groove 103 and move back and forth up and down. At the same time, the guide rod 104 will reciprocate and squeeze the spiral groove 103, thereby causing the rotating drum 102 to rotate.

[0028] Working principle: first pour the rubber powder into the interior of the hopper 6, so that the rubber powder is discharged into the interior of the screening machine 1 through the discharge port 8 and the feed port 7, and falls on the sieve plate 3, and then start the vibration motor 4 to drive the sieve plate 3 to shake, and the rubber powder is screened through the sieve plate 3, and the impurities in the rubber powder are screened out through the sewage outlet 2. At the same time, the cylinder 92 is repeatedly started, and the convex plate 94 can be used to drive the push rod 91 to move back and forth up and down. The push rod 91 can move back and forth up and down in cooperation with the connecting rod 95, so that the guide plate 93 can swing back and forth. The reciprocating swing of the guide plate 93 can evenly guide the rubber powder discharged from the hopper 6 into the screening machine 1 to both sides, so that the falling rubber powder evenly falls on the sieve plate 3, so that the sieve plate 3 can fully screen the rubber powder, and at the same time, it can also prevent the rubber powder that rushes down from accumulating on the sieve plate 3, causing the sieve holes of the sieve plate 3 to be blocked.

[0029] When the push rod 91 slides reciprocatingly up and down, it will drive the guide rod 104 to move reciprocatingly up and down in contact with the inner wall of the spiral groove 103. At the same time, the guide rod 104 will reciprocate and squeeze the spiral groove 103, thereby causing the rotating drum 102 to rotate. At the same time, the cross bar 101 can drive the hopper 6 to rotate synchronously. When the discharge port 8 at the bottom of the hopper 6 rotates to overlap with the feed port 7, the rubber powder inside the hopper 6 can be discharged downward into the interior of the screening machine 1 through the discharge port 8 and the feed port 7. When the discharge port 8 rotates to be completely offset from the feed port 7, the rubber powder inside the hopper 6 stops discharging. Through the reciprocating rotation of the hopper 6, in conjunction with the discharge port 8 and the feed port 7, the rubber powder can be delivered to the interior of the screening machine 1 in small quantities for multiple times to avoid excessive accumulation of rubber powder on the sieve plate 3, thereby effectively preventing the mesh of the sieve plate 3 from being blocked by rubber powder.

[0030] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
