Description

Technical Field

[0001] This utility model relates to the technical field of raw material screening device for the production of biodegradable fiber additives, specifically a raw material screening device for the production of biodegradable fiber additives. Background Technology

[0002] With the advancement of the global goal of "carbon neutrality" and the increasing demand for green materials in industries such as textiles and packaging, biodegradable fibers are gradually becoming an important alternative to traditional petroleum-based synthetic fibers. These fibers effectively solve the "white pollution" problem caused by the long-term accumulation of waste textiles. However, the performance of biodegradable fibers (such as mechanical strength, thermal stability, and processing fluidity) depends not only on the structure of their main polymer chain but also on the type and dispersibility of additives. Biodegradable fiber additives are a class of functional auxiliaries used to improve the functionality of fibers. They mainly include nucleating agents, plasticizers, antioxidants / UV absorbers, and compatibilizers. The raw materials for these additives have complex forms (may be powders, granules, amorphous lumps, or agglomerates) and have extremely high requirements for particle size distribution, purity, and uniformity. If unground lumps or agglomerates are mixed in the raw materials, it will affect the stability of subsequent mixing processes and ultimately reduce the overall performance of the fibers. Therefore, raw material screening is a key pretreatment step in the production of biodegradable fiber additives.

[0003] Currently, most raw material screening devices use a drive motor to drive the vibrating screen or drive the drum to rotate for screening. However, the size of the screening holes inside the traditional vibrating screen and screening drum is fixed and difficult to adjust. This means that when screening fiber additives, the vibrating screen can only screen materials with a single particle diameter. As a result, the material needs to be screened a second time after a single screening, which leads to low working efficiency of the screening device and the problem of low practicality of traditional raw material screening devices.

[0004] The screening of biodegradable fiber additive raw materials is carried out using a vibrating screen or drum screen. Utility Model Content

[0005] The purpose of this invention is to provide a raw material screening device for the production of biodegradable fiber additives, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a raw material screening device for the production of biodegradable fiber additives, including a support platform, a screening box fixedly connected to the top of the support platform, a feed hopper fixedly sleeved on the top of the screening box, a sorting screen movably sleeved inside the screening box, a discharge hopper movably sleeved inside the screening box, and a screening mechanism provided inside the screening box, the screening mechanism including:

[0007] A drive motor is fixedly installed on the top of the screening box. A drive column is fixedly connected to the output shaft of the drive motor. The drive column is movably sleeved inside the sorting screen. A rotating protrusion is fixedly sleeved on the outside of the drive column.

[0008] Preferably, a sliding ball is movably sleeved on the top of the rotating protrusion, the sliding ball is in close contact with the bottom of the sorting screen, and there are three sliding balls. An auxiliary mechanism is provided inside the screening box, and a material receiving mechanism is provided on the side of the screening box.

[0009] Preferably, the auxiliary mechanism includes a positioning block, which is fixedly connected to the side of the inner wall of the screening box. A limiting post is movably sleeved inside the positioning block. One end of the limiting post is fixedly connected to the bottom of the sorting screen. A tension spring is movably sleeved at the bottom of the limiting post, and one end of the tension spring is fixedly connected to the bottom of the positioning block.

[0010] Preferably, the receiving mechanism includes a limiting cover, which is fixedly connected to the side of the screening box, movably sleeved on the side of the sorting screen, a storage bag is fixedly sleeved on the side of the limiting cover, and an elastic band is fixedly sleeved on the side of the limiting cover.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This raw material screening device for the production of biodegradable fiber additives, by setting a screening mechanism, when additive screening is required, the additive raw material is put into the inside of the feed hopper. At this time, the drive motor is started, so that the drive motor drives multiple rotating protrusions to rotate through the drive column. As a result, the rotation of multiple rotating protrusions pushes multiple sorting screens to vibrate up and down, so that the material enters the sorting screen with a diameter of three millimeters through the feed hopper for single screening. Then, it is screened multiple times through multiple sorting screens with progressively decreasing aperture values, thereby achieving the effect of simultaneous multi-stage screening of additives, and thus greatly improving the working efficiency of the screening device.

[0012] In addition, this raw material screening device for the production of biodegradable fiber additives also features a rotating protrusion. When the screening screen is driven to vibrate for material screening, the rotating protrusion drives the sliding ball to rotate, which in turn pushes the screening screen to rise and fall by rolling. This avoids the problem of friction between the rotating protrusion and the bottom of the screening screen when the rotating protrusion pushes the screening screen to rise and fall, thereby improving the smoothness of the rotating protrusion's rotation, which in turn improves the smoothness of the screening screen's rise and fall, and thus greatly extends the service life of the screening device.

[0022] Please see Figure 1 and Figure 3 This utility model provides an embodiment of a raw material screening device for the production of biodegradable fiber additives, including a support platform 1, a screening box 2 fixedly connected to the top of the support platform 1, a feed hopper 3 fixedly sleeved on the top of the screening box 2, a sorting screen 4 movably sleeved inside the screening box 2, a discharge hopper 5 movably sleeved inside the screening box 2, a screening mechanism 6 provided inside the screening box 2, the screening mechanism 6 including a drive motor 61, the drive motor 61 fixedly installed on the top of the screening box 2, a drive column 62 fixedly connected to the output shaft of the drive motor 61, the drive column 62 movably sleeved inside the sorting screen 4, and a rotating protrusion 63 fixedly sleeved on the outside of the drive column 62; by setting the screen In sub-mechanism 6, when additive screening is required, the additive raw materials are fed into the feed hopper 3. At this time, the drive motor 61 (model YZU-10-2, power 1.5kw) is started, which drives multiple rotating protrusions 63 to rotate through the drive column 62. The rotation of the multiple rotating protrusions 63 pushes multiple sorting screens 4 to vibrate up and down, so that the material enters the sorting screen 4 with a diameter of 3mm through the feed hopper 3 for single screening. Then, it is screened multiple times through multiple sorting screens 4 with progressively decreasing aperture values, thereby achieving the effect of simultaneous multi-stage screening of additives and greatly improving the working efficiency of the screening device.

[0023] Please see Figure 1 The top of the rotating protrusion 63 is movably fitted with a sliding ball 7, which is in close contact with the bottom of the sorting screen 4. There are three sliding balls 7. An auxiliary mechanism 8 is provided inside the screening box 2, and a material receiving mechanism 9 is provided on the side of the screening box 2. By setting the rotating protrusion 63, when the sorting screen 4 is driven to vibrate for material screening, the rotating protrusion 63 can drive the sliding ball 7 to rotate, so that the sliding ball 7 can push the sorting screen 4 to rise and fall by rolling. This avoids the problem of friction between the rotating protrusion 63 and the bottom of the sorting screen 4 when the rotating protrusion 63 pushes the sorting screen 4 to rise and fall, thereby improving the smoothness of the rotation of the rotating protrusion 63, that is, improving the smoothness of the rise and fall of the sorting screen 4.

[0024] Please see Figure 1 and Figure 3The auxiliary mechanism 8 includes a positioning block 81, which is fixedly connected to the side of the inner wall of the screening box 2. A limiting post 82 is movably sleeved inside the positioning block 81. One end of the limiting post 82 is fixedly connected to the bottom of the sorting screen 4. A tension spring 83 is movably sleeved at the bottom of the limiting post 82, and one end of the tension spring 83 is fixedly connected to the bottom of the positioning block 81. By setting the auxiliary mechanism 8, when the sorting screen 4 vibrates up and down to screen materials, the positioning block 81 and the tension spring 83 can limit the up-and-down movement of the limiting post 82, that is, limit the up-and-down movement of the sorting screen 4, so as to avoid the problem of tilting and displacement when the sorting screen 4 moves up and down, thereby improving the stability of the sorting screen 4 when vibrating.

[0025] Please see Figure 2 The receiving mechanism 9 includes a limiting cover 91, which is fixedly connected to the side of the screening box 2 and movably sleeved on the side of the sorting screen 4. A storage bag 92 is fixedly sleeved on the side of the limiting cover 91, and an elastic band 93 is fixedly sleeved on the side of the limiting cover 91. By setting up the receiving mechanism 9, when the additive screening is finished, the storage bag 92 is sleeved on the side of the limiting cover 91. At this time, the elastic band 93 is sleeved on the side of the limiting cover 91, so that the elastic band 93 can fix the storage bag 92 on the side of the limiting cover 91, that is, drive the storage bag 92 to be sleeved on the side of the sorting screen 4, so that the sorted material can be discharged into the storage bag 92 through the sorting screen 4, thereby bringing convenience to the storage of the sorted material.

[0026] Working principle: When additive screening is required, the additive raw materials are fed into the feed hopper 3. At this time, the YZU-10-2 1.5kw drive motor 61 is started, which drives multiple rotating protrusions 63 to rotate through the drive column 62. The rotation of the multiple rotating protrusions 63 pushes multiple sorting screens 4 to vibrate up and down, so that the material enters the sorting screen 4 with a diameter of 3mm through the feed hopper 3 for single screening. Then, it is screened multiple times through multiple sorting screens 4 with progressively decreasing aperture values, thus achieving the effect of multi-stage screening of additives at the same time, which greatly improves the working efficiency of the screening device. When the sorting screen 4 is driven to vibrate to screen the material, the rotating protrusions 63 drive the sliding ball 7 to rotate, so that the sliding ball 7 pushes the sorting screen 4 to rise and fall by rolling. This avoids the problem of friction between the rotating protrusions 63 and the bottom of the sorting screen 4 when the rotating protrusions 63 push the sorting screen 4 to rise and fall, thus improving the smoothness of the rotation of the rotating protrusions 63, that is, improving the smoothness of the rise and fall of the sorting screen 4.

[0027] When the sorting screen 4 vibrates up and down to screen materials, the positioning block 81 and the tension spring 83 limit the vertical movement of the limiting column 82, thus limiting the vertical movement of the sorting screen 4. This prevents the sorting screen 4 from tilting or shifting during vertical movement, thereby improving the stability of the sorting screen 4 during vibration. When the additive screening is finished, the storage bag 92 is fitted onto the side of the limiting cover 91. At this time, the elastic band 93 is fitted onto the side of the limiting cover 91, so that the elastic band 93 can fix the storage bag 92 onto the side of the limiting cover 91. This means that the storage bag 92 is fitted onto the side of the sorting screen 4, allowing the sorted material to be discharged into the storage bag 92 through the sorting screen 4, thus facilitating the storage of sorted materials. The contents not described in detail in this description are existing technologies known to those skilled in the art.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
