Description

Technical Field

[0001] This utility model belongs to the field of screening technology, and in particular to a material screening device. Background Technology

[0002] After chemical materials are mixed, the chemical particles need to be sieved to select materials with suitable particle diameters. Existing equipment requires manual pouring of the mixed materials into the sieve and then out through the same sieve opening. The amount poured in manually each time is difficult to control, which not only leads to low sieving efficiency but also results in the sieved material being poured into materials with mismatched diameters, leading to material waste. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a material screening device that features material saving.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A material screening device includes a discharge structure, a support plate, a feed cylinder, and a large gear. The bottom of the discharge structure is connected to a support frame. The discharge structure is hollow inside, with one end connected to the support plate. A feed cylinder is located inside the discharge structure. Several screen holes of suitable diameter are formed on the wall of the feed cylinder. A cover plate assembly is connected to one end of the feed cylinder. The end of the feed cylinder connected to the cover plate assembly is slightly lower than the other end, and the diameter of the end connected to the cover plate assembly is smaller than that of the other end. A fixing ring and a first connecting post are connected to the cover plate assembly, and the fixing ring is connected to the cover plate assembly.

[0006] One end of the first connecting post is fixedly connected to the cover plate assembly, and the other end is rotatably connected to one end of the rotating component. The other end of the rotating component is connected to the third connecting post, one end of which is connected to the rotating component, and the other end is connected to the large gear.

[0007] The large gear has an oblong hole, and a second connecting post is slidably connected within the oblong hole. The end of the second connecting post away from the large gear is fixedly connected to a support plate. The large gear is rotatably connected to a small gear, and the small gear is connected to the motor output shaft.

[0008] Furthermore, the discharge structure includes a discharge cylinder and a sealing plate.

[0009] Furthermore, a conveyor belt structure is provided below the cover plate assembly.

[0010] Furthermore, the motor is connected to the support frame.

[0011] Furthermore, the supporting frame includes support rods and support feet, and is also fixedly connected to the support plate.

[0012] Furthermore, the inlet of the feed cylinder faces upwards.

[0013] Compared with the prior art, this utility model has the following advantages: the motor drives the small gear to rotate, which in turn drives the large gear, so that the cover plate assembly has a periodic opening and closing motion trajectory, realizing the automatic opening and closing function. With the cover plate assembly structure set, manual or other devices are still needed to assist in transporting the material into the feed cylinder during material screening. After screening, it can be conveyed in two directions, which helps to ensure the purity of the material after screening. At the same time, by setting an appropriate time, the screening efficiency of the device can be improved. Attached Figure Description

Detailed Implementation

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] like Figure 1-5As shown, a material screening device includes a discharge structure 1, a support plate 2, a feed cylinder 3, and a large gear 9. The bottom of the discharge structure 1 is connected to a support frame 7. The discharge structure 1 is hollow inside, with one end connected to the support plate 2. The discharge structure 1 contains a feed cylinder 3, and the cylinder wall of the feed cylinder 3 has several screen holes 4 of suitable diameter. One end of the feed cylinder 3 is connected to a cover plate assembly 5, which is slightly lower than the other end and has a smaller diameter than the other end. A fixing ring 17 and a first connecting post 6 are connected to the cover plate assembly 5, and the fixing ring 17 is connected to the cover plate assembly 5.

[0022] One end of the first connecting post 6 is fixedly connected to the cover plate assembly 5, and the other end is rotatably connected to one end of the rotating component 8. The other end of the rotating component 8 is connected to the third connecting post 15, one end of which is connected to the rotating component 8, and the other end is connected to the large gear 9.

[0023] The large gear 9 has an oblong hole 13, and a second connecting post 14 is slidably connected inside the oblong hole 13. The end of the second connecting post 14 away from the large gear 9 is fixedly connected to the support plate 2. The large gear 9 is rotatably connected to the small gear 10, and the small gear 10 is connected to the output shaft of the motor 11.

[0024] In this invention, when the motor 11 rotates counterclockwise by a certain angle, it drives the small gear 10 to rotate counterclockwise, which in turn drives the large gear 9 to rotate clockwise. The rotating component 8 rotates, and the cover plate rotates, allowing both ends of the feed cylinder 3 to communicate with the air. Conversely, when the motor 11 rotates clockwise back by a certain angle, the cover plate closes, closing one end of the feed cylinder 3. Before screening, materials can be manually or automatically transported into the feed cylinder 3. By setting the forward and reverse rotation times of the motor, the cover plate assembly 5 can be opened and closed periodically. When the cover plate assembly 5 is open, because the feed cylinder 3 is lower on the side closest to the cover plate, most of the waste material will fall directly out of the feed cylinder 3 due to the loss of support from the cover plate assembly 5. If there is less waste material, manual assistance is still needed to clean out some of the screened waste.

[0025] like Figure 1 As shown, the discharge structure 1 includes a discharge cylinder 18 and a sealing plate 19. In this invention, the discharge cylinder 18 is larger than the feed cylinder 3, allowing material to leak out through the gaps during discharge. The sealing plate 19 effectively blocks the leakage of material, ensuring that the filtered material can only be poured out from one end.

[0026] like Figure 5As shown, a conveyor belt structure 16 is provided below the cover plate assembly 5. After the cover plate assembly 5 is rotated open, materials that do not conform to the particle diameter can pass through the cover plate assembly 5 into a transport bag, which can be placed on the conveyor belt structure 16. In conventional production screening devices, the material before screening and the unqualified material are fed and discharged through the same inlet. When the unqualified material is poured out, it may still mix with the qualified material, ultimately resulting in the presence of impurities. This utility model sets up different inlets and outlets, which largely avoids the generation of impurities.

[0027] like Figure 5 As shown, the motor 11 is connected to the support frame 7.

[0028] like Figure 5 As shown, the supporting frame 7 includes a supporting rod 71 and a supporting foot 72; the supporting frame 7 is also fixedly connected to the supporting plate 2.

[0029] This utility model securely mounts the motor 11 onto the device using a support frame 7. By adjusting the motor's operating time, the motor 11 rotates in both directions within a certain time period, causing the pinion 10 to drive the gear 9 in reciprocating motion. This allows the cover plate assembly 5 to open and close, facilitating the loading and unloading of materials.

[0030] like Figure 3 As shown, the inlet of feed cylinder 3 faces upwards. This upward orientation prevents the material from easily exiting the feed inlet. Due to gravity and inertia, the material will fall downwards, thus achieving material screening.

[0031] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0032] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Meanwhile, the meaning of "and / or" throughout the text includes three solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0033] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0034] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0035] Although this document uses terms such as discharge structure, support plate, feed cylinder, screen hole, cover plate assembly, and first connecting column frequently, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any kind of additional limitation would contradict the spirit of this utility model.
