Description

Technical Field

[0001] The invention relates to the technical field of screening equipment, and in particular to a masterbatch vibration screening equipment. Background Art

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) The masterbatch vibration screening device, when it is necessary to screen the masterbatch, the staff can add the masterbatch into the screening box from the top opening of the screening box. When adding the masterbatch, the masterbatch will fall on the screening plate, thereby achieving the purpose of screening the masterbatch. At the same time, the motor can be started to drive the rotating shaft to rotate. The rotating effect of the rotating shaft can be used to drive the connecting column to drive the arc rotating plate to rotate. The rotation process can be used to drive the connecting rod and the arc spreading plate to move along the outer surface of the arc rod during the rotation. When the arc spreading plate rotates to the lowest side, part of the masterbatch can be retained in the spreading trough. When it is rotating, the masterbatch in the spreading trough can be spread outwards by using its rotation process, so that the material can be turned over and the rate at which the masterbatch passes through the screening plate can be accelerated, thereby enhancing the screening effect of the device on the masterbatch.

[0015] (2) The masterbatch vibration screening equipment can drive the rotating teeth to rotate during the rotation of the arc-shaped rotating plate. When the rotating teeth rotate to a certain position, the pulling teeth can be pulled. Under the pulling effect, the semicircular pull rod can be moved laterally. The lateral movement effect of the semicircular pull rod can be used to move the pulling rake along the top outer wall of the upper screening plate. The moving effect of the pulling rake can be used to separate the adhered parts of the masterbatch, thereby enhancing the screening effect of the masterbatch.

[0016] (3) In the masterbatch vibration screening device, when the rotating tooth is pulling the pulling tooth, and the pulling tooth pulls the semicircular pull rod to the limit position, the pulling tooth will no longer move, but the rotating tooth will continue to rotate, so that the rotating tooth can exert a downward pressure on the pulling tooth. Under the action of pressure, the screening plate can vibrate up and down under the action of the slider, so that the vibration effect can be used to accelerate the rate at which the masterbatch passes through the screening plate, thereby enhancing the screening effect of the device on the masterbatch.

[0017] (4) The masterbatch vibration screening device can extrude the semicircular elastic rubber tube in a gap shape during the rotation of the rotating teeth and the arc-shaped spreading plate. Under the extrusion effect, the semicircular elastic rubber tube can be deformed, thereby squeezing the gas inside the air pressure box. Under the extrusion effect, the gas can push the air pressure plate to move, which can drive the T-shaped vibration plate to vibrate up and down, and can drive the vibration spring and the vibration impact column to impact the bottom of the screening plate, so as to utilize the impact vibration effect to enhance the vibration effect of the screening plate, thereby enhancing the screening effect of the device on the masterbatch.

[0051] A specific application of this embodiment is:

[0052] When it is necessary to screen the masterbatch, the staff can add the masterbatch into the screening box 1 from the top opening of the screening box 1. When adding, the masterbatch will fall on the screening plate 14, so as to achieve the purpose of screening the masterbatch. At the same time, starting the motor 21 can drive the rotating shaft 2 to rotate. The rotating effect of the rotating shaft 2 can be used to drive the connecting column 22 to drive the arc rotating plate 23 to rotate. The rotation process can be used to drive the counterweight block 32 to drive the connecting rod 33 and the arc spreading plate 34 to move along the outer surface of the arc rod 31 during the rotation. In this way, when the arc spreading plate 34 rotates to the lowest side, part of the masterbatch can be retained in the spreading trough 35. When it rotates, The rotation process can be used to spread the masterbatch inside the spreading trough 35 to the outside, so that the material can be turned over and the rate at which the masterbatch passes through the screening plate 14 can be accelerated, thereby enhancing the screening effect of the device on the masterbatch. Secondly, during the rotation of the arc-shaped rotating plate 23, the rotating tooth 53 can be driven to rotate. When it rotates to a certain position, the pulling tooth 52 can be pulled. Under the pulling effect, the semicircular pull rod 51 can be moved laterally. The lateral movement effect of the semicircular pull rod 51 can be used to make the pulling rake 61 move along the top outer wall of the upper screening plate 14, so that the moving effect of the pulling rake 61 can be used to separate the adhered parts of the masterbatch, thereby enhancing the screening effect of the masterbatch.

[0053] At the same time, when the rotating tooth 53 is pulling the pulling tooth 52, when the pulling tooth 52 pulls the semicircular pull rod 51 to the limit position, the pulling tooth 52 will no longer move, but the rotating tooth 53 will continue to rotate, so that the rotating tooth 53 can exert a downward pressure on the pulling tooth 52. Under the action of pressure, the screening plate 14 can vibrate up and down under the action of the slider 43, so as to utilize its vibration effect to accelerate the speed of the masterbatch passing through the screening plate 14, thereby enhancing the screening effect of the device on the masterbatch. Secondly, between the rotating tooth 53 and the arc-shaped spreading plate During the rotation process 34, the semicircular elastic rubber tube 71 can be squeezed in a gap shape. Under the squeezing effect, the semicircular elastic rubber tube 71 can be deformed, and then the gas inside the air pressure box 7 can be squeezed. Under the squeezing effect, the gas can push the air pressure plate 8 to move, which can drive the T-shaped vibration plate 82 to vibrate up and down, and can drive the vibration spring 9 and the vibration impact column 91 to impact the bottom of the screening plate 14, so as to utilize its impact vibration effect to enhance the vibration effect of the screening plate 14, thereby enhancing the screening effect of the device on the masterbatch.
