[0002] During the processing of plastic products, it is usually necessary to add stabilizers in a targeted manner to achieve specific performance. However, there are usually certain impurities in the stabilizers. During use, the presence of impurities can easily cause the quality of plastic products to deteriorate. It is necessary to remove impurities from the raw materials of the stabilizer. Usually, the raw materials and impurities are directly filtered through a sieve plate. This operation is more labor-intensive and time-consuming, and the impurity removal efficiency is low.

[0003] China Patent Authorization Announcement Number: CN 209953219 U, Authorization Announcement Date: January 17, 2020. This utility model relates to a powder material impurity removal device for processing plastic stabilizers, comprising a material receiving box, a material protection frame, an impurity removal screen plate, and a drive motor. The impurity removal screen plate is connected to the lower surface of the material protection frame by screws. The left and right side walls of the material protection frame are provided with cross bars. The outer wall of the cross bar is sleeved with a sliding sleeve. The sliding sleeve is connected to the corresponding side wall of the material receiving box through a bracket. A reset spring is supported between the sliding sleeve and the corresponding side wall of the material receiving box. The shortcomings of this technical solution are: 1. The impurity removal screen plate is easily clogged, resulting in reduced impurity removal efficiency; 2. The device can only receive the powder material through the material receiving box. The impurities after impurity removal are difficult to remove, which reduces the practicality of the device.

[0004] In summary, the impurity removal device has the disadvantages of being easily clogged, being inconvenient to remove impurities, and reducing screening efficiency and practicality. Utility Model Content

[0028] like Figure 3 As shown, the driving assembly includes a support plate 19, and the bracket 1 is provided with a movable slide 20. One end of the support plate 19 is slidably connected to the movable slide 20, and the other end of the support plate 19 is attached to the screening box 3. There are two support plates 19 and they are respectively placed on both sides of the screening box 3.

[0029] like Figure 1 、 2 As shown, the bracket 1 is provided with a limiting chute 21, the powder box 4 and the debris box 5 are both connected with a sliding rod 22, the sliding rod 22 is slidably connected to the limiting chute 21, and the groove wall of the limiting chute 21 is provided with a positioning groove 23, the size of the positioning groove 23 is adapted to the sliding rod 22.

[0030] like Figure 1 、 2 As shown in 4, the upper ends of the powder box 4 and the debris box 5 are provided with a collection port 24, and the lower ends of the powder box 4 and the debris box 5 are provided with a discharge port 25. The discharge port 25 is provided with a switch structure, which includes a switch plate 26, a rotating shaft 27 and a clamping block 28. One end of the rotating shaft 27 is plugged into the discharge port 25, and the other end of the rotating shaft 27 is plugged into the switch plate 26. One end of the clamping block 28 is connected to the switch plate 26, and the other end of the clamping block 28 is clamped into the discharge port 25.

[0031] like Figure 1-4 As shown: the end of the connecting rod 11 is connected with a protrusion 29, one end of the elastic mechanism 12 is connected to the protrusion, and the other end of the elastic mechanism 12 is connected to the moving rod 10, so that the extension and retraction of the elastic mechanism 12 is more stable.

[0032] Two connecting shafts 13 are respectively placed on both sides of the screening box 3, one connecting shaft 13 is connected to the elastic mechanism 15, and the other connecting shaft 13 is placed on the side close to the rotating machine 17, so that the sieve hole 7 and the needle body 8 are easier to dock and prevent the elastic mechanism 15 from affecting the alignment.

[0033] The actual size of the sieve hole 7 is adapted to the powder to be screened and filtered, and the size of the needle body 8 is smaller than the diameter of the sieve hole 7 so that it can be smoothly inserted into the sieve hole 7 for dredging and cleaning.

[0034] The rotating block 18 is of a special-shaped structure with one side protruding from the other side so as to facilitate the operation of repeatedly pushing the screening box 3 through the rotating mechanism 16 .

[0035] The movable chute 20 has an L-shaped structure (not shown in the figure), so that the support plate 19 can be against the right angle of the movable chute to prevent the push of the screening box 3 from moving in the movable chute 20. When in use, the support plate 19 is positioned and fixed by sliding it and finally against the bend.

[0036] The connecting shaft 13 has a cylindrical end and extends into the screening box 3 . A limiting block 30 is connected to the end to prevent the connecting shaft 13 from being separated from the screening box 3 during movement.

[0037] The inner wall of the discharge port 25 is provided with a card slot (not shown in the figure), so that the card block 28 can be locked into the card slot when the switch plate 26 is in a horizontal state, making the switch plate 26 more stable.

[0038] During use: remove impurities and collect powder: introduce the plastic stabilizer powder into the screening box 3, place the sliding rod 22 of the powder box 4 in the positioning groove 23, start the rotating mechanism 17, and rotate the rotating block 18. The protruding side of the special-shaped rotating block 18 pushes the screening box 3 during rotation, so that the screening box 3 squeezes the elastic mechanism 2 16 (using a spring). The shorter side of the rotating block 18 causes the screening box 3 to be reset by the restoring force of the elastic mechanism 2 16, and then the screening box 3 repeatedly moves horizontally to screen the powder, and sieve the required powder into the sieve hole 7 and enters the powder box 4 below, thereby realizing the separation of the powder and impurities.

[0039] Collect debris: Lift the powder box 4 and slide it along the limiting chute 21 away from under the feed port 2. Move the debris box 5 until the sliding rod 22 enters the positioning groove 23. At this time, the debris box 5 is placed under the feed port 2. Move the support block 19 so that the support block 19 is away from the lower end surface of the screening box 3. Rotate the screening box 3 so that the debris in the screening box 3 passes through the feed port 2 and enters the debris box 5, and is collected by the debris box 5. Remove the debris box 5, reset the powder box 4 and support plate 19, and start screening again.

[0040] Prevent the sieve hole 7 from being blocked: No material is poured into the screening box 3, and the movable plate 6 is moved on the guide chute 9 by the movable rod 10. The movable rod 9 is placed at the end of the guide chute 9, and the inner wall of the screening box 3 is in contact with the limiting block 30 at one end of the connecting shaft 13 that is not connected. That is, the sieve hole 7 and the needle body 8 are in a one-to-one relative state in the upper and lower positions. The elastic force of the elastic mechanism 12 is overcome to pull down the movable plate 6, so that the needle body 8 enters the sieve hole 7 and pierces the hole to clear the hole. After cleaning, the movable plate 6 is released to retract and reset the movable plate 6 to complete the anti-blocking cleaning.

[0041] Unloading powder box 4 or debris box 5: push one side of the switch plate 26, so that the switch plate 26 rotates under the support of the fulcrum of the rotating shaft 27, and the buckle 28 on the other side is pushed out of the slot, and then the switch plate 26 is flipped from horizontal to vertical, and the unloading port 25 is opened for centralized unloading and collection.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
