[0002] Injection molding raw materials are important materials used to manufacture plastic products and play a vital role in the injection molding process. These raw materials are usually thermoplastics that can be formed into the desired product shape in the mold through heating and plasticization.

[0003] The existing authorization announcement number CN206840489U discloses a screening device for raw materials for injection molding. The device is equipped with a mesh plate to filter out large impurities, and then removes impurities attached to the raw materials through the back-and-forth movement of the movable plate. Finally, the material release plate is opened to take out the raw materials. The structure of this device is relatively simple, the cost is relatively low, and it is suitable for promotion and use.

[0004] The above technical solution can filter out large impurities by installing a mesh plate, and then remove impurities attached to the raw materials through the back-and-forth movement of the movable plate. However, during the screening process, the raw materials for injection molding may become stuck inside the sieve plate. The sieve plate is fixed inside the screening device and is difficult to clean. Long-term use can cause blockage inside the screening device, thereby affecting the subsequent working efficiency of the screening device. Therefore, we provide a screening device for injection molding raw materials. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0024] The utility model provides a technical solution: Figure 1-Figure 4As shown, in this embodiment, a screening device for raw materials for injection molding comprises: a screening mechanism 1, the screening mechanism 1 comprises a screening box 11, a first screening slot 12 is provided on one side of the screening box 11, a first sieve plate 13 is provided inside the first screening slot 12, a second screening slot 14 is provided on one side of the screening box 11 near the bottom of the first screening slot 12, a second sieve plate 15 is provided inside the second screening slot 14, the outside of the first sieve plate 13 is docked in the first screening slot 12, the outside of the second sieve plate 15 is docked in the second screening slot 14, a third screening slot 16 is provided on one side of the screening box 11 near the bottom of the second screening slot 14, a filter screen 17 is provided inside the third screening slot 16, sliders 19 are provided on both sides of the first sieve plate 13, the second sieve plate 15 and the filter screen 17, the outside of the filter screen 17 is docked in the third screening slot 16, the first sieve plate 13. Sliders 19 are fixedly connected to both sides of the second screen plate 15 and the filter screen 17. Sliders 19 are provided on both sides of the inner walls of the first screening trough 12, the second screening trough 14 and the third screening trough 16. A collecting box 110 is provided at the bottom of the inner wall of the screening box 11. Two pulleys 111 are provided on both sides of the bottom of the collecting box 110. The outside of the slide 19 is slidably connected to the inner wall of the slide 18. The collecting box 110 is docked in a slot opened on the side of the screening box 11 away from the mounting shell 21. Pulleys 111 are fixedly installed on both sides of the bottom of the collecting box 110. Two slide rails 112 are provided on the bottom side of the inner wall of the screening box 11. The outside of the pulley 111 is slidably connected to the inner wall of the slide rail 112. The feed port 31 is fixedly connected in the slot opened at the top of the screening box 11. An auxiliary mechanism 2 is provided on the side of the screening box 11 away from the first screening trough 12.

[0025] In this embodiment, when it is necessary to screen the raw materials for injection molding that meet the specifications, the raw materials can be put into the screening box 11 through the feed port 31, and the raw materials will fall on the first sieve plate 13. It is mentioned here that the mesh diameter of the first sieve plate 13 is slightly larger than the mesh diameter of the second sieve plate 15, so some relatively coarse raw materials can be isolated on the first sieve plate 13, and the relatively fine raw materials will be screened and fall on the second sieve plate 15. In addition, the filter screen 17 is the final screening component, and the diameter of its mesh port will be more precise, and then the raw materials will pass through the second sieve plate 15. The raw materials that fall through the sieve plate 15 will fall onto the filter screen 17, and the injection molding raw materials that meet the specifications will be screened into the collection box 110 through the filter screen 17. However, some raw materials may be blocked in the sieve holes of these sieve components. After the device is finished working, the staff can use the slider 19 and the slide 18 to pull the first sieve plate 13, the second sieve plate 15 and the filter screen 17 out of the screening box 11, and then clear the raw materials that are blocked on the first sieve plate 13, the second sieve plate 15 and the filter screen 17 to ensure the subsequent working efficiency of the screening device.

[0026] like Figure 2-Figure 4As shown, the auxiliary mechanism 2 includes a mounting shell 21, the top of the mounting shell 21 is fixedly mounted to the bottom of the motor 22, one side of the mounting shell 21 is fixedly connected to the outside of the screening box 11, the output end of the bottom of the motor 22 passes through the top of the mounting shell 21 and is fixedly connected to the top of the beating paddle 23, the bottom of the beating paddle 23 is fixedly connected to the inner surface of the bearing seat 24, and the bottom of the bearing seat 24 is fixedly connected to the bottom side of the inner wall of the mounting shell 21.

[0027] In this embodiment, in order to ensure the screening efficiency of the screening device for raw materials, the staff can start the motor 22 to drive the beating paddle 23 to rotate, and then the outer edge of the beating paddle 23 will continue to beat the outside of the screening box 11, and then the vibration generated when the screening box 11 is beaten will accelerate the screening efficiency of the screening component.

[0028] The utility model provides a screening device for raw materials for injection molding, and the specific working principle is as follows:

[0029] In the injection molding production process, the screening of raw materials is a crucial step. In order to ensure the quality of injection molded products, it is necessary to accurately screen the raw materials for injection molding that meet the specifications. First, the raw materials to be screened are put into the screening box 11 through the feed port 31. The raw materials will fall naturally and fall on the first screen plate 13. At this time, the motor 22 is started, and the motor 22 will drive the flapping paddle 23 to rotate. The design of the flapping paddle 23 enables its outer edge to continuously flap the outer side of the screening box 11. This flapping action will generate vibration, and this vibration is the key to accelerating the screening process. When the screening box 11 is flapped, When the machine vibrates, the injection molding raw materials that meet the specifications will pass through the first sieve plate 13, the second sieve plate 15 and the filter screen 17 more quickly. These sieve plates and the filter screen 17 are designed to ensure that only the raw materials that meet the specifications can pass through, thereby ensuring the quality of the raw materials after screening. Finally, the screened raw materials will fall into the collection box 110. In order to facilitate the removal of the screened raw materials, the collection box 110 is equipped with a pulley 111 and a slide rail 112. Through the combination of the pulley 111 and the slide rail 112, the collection box 110 containing the screened raw materials can be easily removed from the bottom of the screening box 11 to prepare for subsequent injection molding production.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
