Description

Technical Field

[0001] The utility model relates to the technical field of screening, in particular to a screening device for caking of color powder of injection molded parts. Background Technique

[0002] If the color powder used in the coloring process of injection molded parts cakes, it will affect the color uniformity and appearance quality of plastic products. Therefore, it is necessary to screen the color powder to remove caking and ensure the uniform dispersion of the color powder. However, the existing devices have certain drawbacks in use. For example, a screening device for processing color powder materials described in the publication number CN212238195U includes a screening box. A first screen is horizontally and fixedly connected to the inner bottom of the screening box. A motor is fixedly installed in the middle of the upper surface of the screening box. The output end of the motor is connected to a transmission rod. The transmission rod is vertically placed in the middle of the screening box, and stirring plates are fixedly installed on both the left and right sides of the bottom of the transmission rod. The bottom right side of the outer wall of the screening box is fixedly communicated with a connecting pipe. A valve is arranged on the connecting pipe, and the other end of the connecting pipe is fixedly communicated with the top left side of the outer wall of the processing box.

[0003] Although the above device can crush the color powder that does not pass through the first screen, after the color powder is crushed, it falls onto the second screen under the action of gravity, and the falling position is relatively concentrated without spreading operation, resulting in a low screening efficiency of the second screen. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a screening device for caking of color powder of injection molded parts to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0010] Furthermore, mounting legs are fixedly connected to the upper surface of the mounting disc. Bolts are threadedly connected to the outer surfaces of the mounting legs, and the mounting legs are threadedly connected to the mounting half-cylinder through the bolts.

[0011] Furthermore, a gear is fixedly connected to the upper end of the rotating shaft, and the gear is meshed with the toothed ring.

[0012] Preferably, a stirring shaft is rotatably connected to the inside of the blanking cylinder. The output end of the second motor is fixedly connected to the stirring shaft.

A stirring bar is fixedly connected to the end of the blanking auger, and the stirring bar contacts the inner bottom surface of the screening frame.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By providing the crushing roller, the screening frame screens the toner raw materials through the sieve holes.

At the same time, the toothed ring drives the crushing roller to rotate, and the crushing roller cooperates with the crushing blocks to crush the toner raw materials. After crushing, the rotation speed of the screening frame is reduced, and the crushed toner raw materials can be screened, facilitating the screening and crushing of the toner raw materials.

[0015] 2. By providing the stirring shaft, the second motor drives the stirring shaft to rotate. The stirring shaft feeds the toner raw materials in the blanking cylinder through the blanking auger, preventing the raw materials from clogging the blanking port. Moreover, the stirring bar scrapes the screening frame, preventing the toner raw materials from clogging the sieve holes. At the same time, the toner raw materials gathered at the edge position of the screening frame after crushing can be spread out, improving the screening efficiency of the device. The structure of this device is simple, without the need to set multiple filter meshes. By adjusting the rotation speed of the first motor through an external circuit, crushing or screening can be completed. BRIEF DESCRIPTION OF THE DRAWINGS

After crushing, the rotation speed of the screening frame 3 is reduced, and then the crushed toner raw material can be screened, which is convenient for screening and crushing the toner raw material.

[0024] Embodiment 1

[0025] As Figures 1 - 2 shown, the number of the mounting half cylinders 1 is two. The inner surface of one of the mounting half cylinders 1 is fixedly connected with a mounting plate 101.

[0026] In this embodiment, the first motor 103 can drive the mounting plate 4 to rotate. By manually rotating the leveling foot 202, the length of the leveling foot 202 extending out can be changed under the push of the thread, and further leveling operation of the device can be carried out.

[0027] Embodiment 2

[0028] On the basis of Embodiment 1, in order to make up for the problem that it is inconvenient to process the raw materials that have not passed through the screening holes 302 in Embodiment 1.

The stirring shaft 502 discharges the toner raw materials in the blanking cylinder 5 through the blanking auger 503, avoiding the blockage of the blanking port. Moreover, the stirring bar 504 scrapes the screening frame 3, avoiding the blockage of the sieve holes 302 by the toner raw materials. At the same time, the toner raw materials gathered at the edge of the screening frame 3 after crushing can be spread out, improving the screening efficiency of the device.
