Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of color master batch screening, particularly to a color master batch screening device. BACKGROUND

[0002] Color master batch refers to plastic colorant formed by high proportion of pigment or additive and thermoplastic resin through good dispersion, and the caked color master batch needs to be screened in production, so as to prevent the caked color master batch from affecting product production. The existing screening device mostly adopts linear vibrating screen to carry out working operation, and the linear vibrating screen uses vibration motor excitation as vibration power source, so that the material is thrown up and moves on the screen mesh to carry out screening. However, the caked color master batch can be embedded in the screen mesh hole, causing the screen mesh to be completely blocked and unable to screen, and the screening equipment needs to control the feeding amount of the color master batch when screening the color master batch, and once the color master batch accumulated on the screen mesh is too much, the screen mesh will be blocked and unable to work. Therefore, the color master batch screening device is designed to solve the above problems. SUMMARY

[0003] In view of the deficiencies of the existing color master batch screening, the utility model aims to provide a color master batch screening device with the advantages of uniform feeding and preventing the screen mesh from being blocked.

[0004] To achieve the above purpose, one technical scheme of the utility model is as follows: a color master batch screening device, which comprises a screening box, a material box, a feeding screw, a motor, a screen mesh, a vibrating motor and a dredging assembly, the top of the screening box is provided with the material box, the side of the screening box is provided with a waste outlet, and the bottom of the screening box is provided with a screening outlet, the bottom of the material box is provided with an inclined sliding table, the feeding screw is rotatably connected in the inclined sliding table, one end of the feeding screw extends out of the material box and is connected with the output shaft of the motor, the bottom of the inclined sliding table is provided with a feeding port corresponding to one end of the feeding screw, the screening box is provided with a discharging port corresponding to the other end of the feeding screw, the screen mesh is inclinedly arranged in the screening box, the inclined low point of the screen mesh extends out of the waste outlet on the side of the screening box, and the inclined high point of the screen mesh is arranged corresponding to the bottom of the discharging port, the vibrating motor is arranged in the screening box and used for forcing the screen mesh to vibrate, and the bottom of the screen mesh is provided with the dredging assembly used for dredging the screen mesh.

[0005] Preferably, the inner wall of the screening box is provided with a sliding groove located at the bottom of the screen mesh and parallel to the screen mesh.

[0006] Preferably, the unblocking assembly includes a slider, a high-pressure nozzle, an air pipe, a high-pressure air tank, and a lead screw. The high-pressure nozzle slides along a groove at the bottom of the screen. The lead screw is rotatably connected to the groove inside the screening box and meshes with the slider. One end of the lead screw is connected to the output shaft of a motor fixed inside the screening box. The slider has multiple high-pressure nozzles on one side corresponding to the screen. The high-pressure air tank is located outside the screening box. One end of the air pipe is connected to the high-pressure air pipe, and the other end of the air pipe passes through the screening box and is connected to the slider. The slider also has a connecting channel inside, which connects the air pipe and the multiple high-pressure nozzles.

[0007] Preferably, a switch valve for blocking or connecting the gas pipe is also provided between the high-pressure gas tank and the gas pipe;

[0008] The beneficial effects of this utility model are: 1. The feeding screw is driven by a motor to rotate at a uniform speed. The uniformly rotating feeding screw conveys the color masterbatch in the material box to the discharge port evenly. Furthermore, by changing the rotation speed of the feeding screw, the feeding amount of color masterbatch can be changed simultaneously; 2. The gas sprayed by the high-pressure nozzle blows towards the bottom of the screen, forcing the agglomerated color masterbatch embedded in the screen to be blown out and fall from the waste outlet, thereby achieving the effect of clearing the screen and preventing blockage.

[0014] Please see Figures 1 to 2 The embodiments of this utility model include:

[0015] A masterbatch screening device includes a screening box 1, a material box 2, a feed screw 3, a motor 4, a screen 5, a vibrating motor 6, and a clearing component 7. The screening box 1 has a material box 2 on its top, a waste outlet 11 on its side, and a screening outlet 12 at its bottom. The bottom of the material box 2 has an inclined slide 21, in which the feed screw 3 is rotatably connected. One end of the feed screw 3 extends out of the material box 2 and is connected to the output shaft of the motor 4. The bottom of the inclined slide 21 has a feed inlet 22 corresponding to one end of the feed screw 3, and the other end of the screening box 1 has a discharge outlet 13 corresponding to the other end of the feed screw 3. The screen 5 is inclinedly arranged inside the screening box 1. The lowest point of the screen 5 extends out of the waste outlet 11 on the side of the screening box 1, and the highest point of the screen 5 is located at the bottom of the discharge outlet 13. The vibrating motor 6 is arranged inside the screening box 1 to force the screen 5 to vibrate. The bottom of the screen 5 is provided with a clearing component 7 for clearing the screen 5.

[0016] The inner wall of the screening box 1 has a parallel sliding groove 14 located at the bottom of the screen 5;

[0017] The unblocking component 7 includes a slider 71, a high-pressure nozzle 72, an air pipe 73, a high-pressure air tank 74, and a lead screw 75. The high-pressure nozzle 72 slides along the bottom groove 14 of the screen 5. The lead screw 75 is rotatably connected to the groove 14 in parallel within the screening box 1. The lead screw 75 meshes with the slider 71. One end of the lead screw 75 is connected to the output shaft of the motor 4 fixed inside the screening box 1. The slider 71 has multiple high-pressure nozzles 72 on one side of the screen 5. The high-pressure air tank 74 is located outside the screening box 1. One end of the air pipe 73 is connected to the high-pressure air pipe 73. The other end of the air pipe 73 passes through the screening box 1 and is connected to the slider 71. The slider 71 also has a connecting channel inside, which connects the air pipe 73 and the multiple high-pressure nozzles 72.

[0018] There is also a switch valve 8 between the high-pressure gas tank 74 and the gas pipe 73 for blocking or connecting the gas pipe 73;

[0019] With the above settings, its specific working principle in actual operation is as follows:

[0020] When the equipment is screening, the vibration motor 6 is started, and the vibration motor 6 forces the screen 5 connected to it to vibrate synchronously.

[0021] Uniform feeding: First, pour the color masterbatch to be screened into the material box 2. Then, start the motor 4 connected to the feed screw 3 to rotate at a uniform speed. The motor 4 drives the feed screw 3 to rotate at a uniform speed. The uniformly rotating feed screw 3 evenly conveys the color masterbatch in the material box 2 to the discharge port 13, where it falls onto the screen 5 for screening. Furthermore, by changing the rotation speed of the feed screw 3, the amount of color masterbatch fed can be changed simultaneously.

[0022] Unclogging the screen 5: When the screen 5 is blocked by clumps of masterbatch, the motor 4 connected to the lead screw 75 is started first. The motor 4 drives the lead screw 75 to rotate back and forth. The lead screw 75 drives the meshing slider 71 to move back and forth along the slide groove 14. Then, the switch valve 8 between the high-pressure gas tank 74 and the air pipe 73 is opened. The high-pressure gas in the high-pressure gas tank 74 is transported to the high-pressure nozzle 72 through the air pipe 73. During the reciprocating motion of the slider 71 along the slide groove 14, the gas sprayed from the high-pressure nozzle 72 is blown towards the bottom of the screen 5, thereby forcing the clumps of masterbatch embedded in the screen 5 to be blown out and fall from the waste outlet 11, thus achieving the effect of unclogging the screen 5 and preventing blockage.
