Description

Technical Field

[0001] This utility model relates to the field of raw material mixing equipment technology, and in particular to a mixing device for cotton raw materials containing cellulose ester. Background Technology

[0002] In industrial production, the uniform mixing of raw materials is a crucial step in ensuring product quality and performance. This is especially true when handling raw materials like polyester fiber cotton, which have a fibrous structure or are prone to caking due to moisture absorption. Currently, commonly used raw material mixing equipment has significant shortcomings when processing such special materials, directly impacting mixing efficiency and production effectiveness.

[0003] Existing mixing equipment cannot effectively identify and handle clumps formed during the raw material feeding stage. Clumps of raw material enter the mixing container directly. Due to differences in volume and density compared to other bulk raw materials, they are difficult to disperse effectively in the initial stages of mixing. This results in these clumps accumulating at the bottom or in specific areas of the mixing container, failing to be fully mixed. Ultimately, this leads to poor overall uniformity of the mixture, failing to meet production process requirements. Furthermore, during mixing, due to the characteristics of materials like polyester fiber, the agitator blades generate significant centrifugal force or enhance their own adhesion, causing some materials to adhere tightly to the inner wall of the mixing container. These materials adhering to the wall cannot participate in effective mixing circulation, becoming dead zones or ineffective areas in the mixing process. Even with prolonged mixing, they cannot be fully mixed with the main material. Worse still, under certain conditions, dispersed materials may re-agglomerate under mixing, forming new clumps. This re-agglomeration further deteriorates the mixing effect, making it difficult to achieve ideal uniformity even after prolonged mixing. This uneven mixing directly affects the processing performance of subsequent products and the quality stability of the final product.

[0004] Therefore, this utility model proposes a mixing device for cellulose ester cotton raw materials to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems in the prior art that the mixing equipment has when processing cotton raw materials, such as the agglomeration of raw materials leading to uneven mixing, the sticking of raw materials to the wall during the stirring process, and the re-agglomeration of dispersed raw materials, this utility model aims to provide a cotton raw material mixing device with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a mixing device for cellulose acetate raw materials, including a mixing tank, a pre-dispersion mechanism, and a stirring structure disposed on the top of the mixing tank. The pre-dispersion mechanism includes a feed shell, a zigzag roller rotatably connected to the inner wall of the feed shell via bearings, and a zigzag plate fixed to the inner wall of the feed shell and located below the zigzag roller. The stirring structure includes an output machine and a stirring rod connected to the output end of the output machine. An auxiliary mechanism is provided on the outer wall of the stirring rod. The auxiliary mechanism includes a scraper fixedly connected to the outer wall of the stirring rod and a guide plate fixedly connected to the inner wall of the mixing tank. The outer wall of the scraper has an outer groove corresponding to the guide plate.

[0007] Furthermore, the spiked roller forms a shear gap with the spiked plate when rotating, mechanically pulling and dispersing the raw materials entering the mixing tank. The edge of the scraper keeps dynamically in contact with the inner wall of the mixing tank. The guide plate passes through the outer groove when the stirring rod rotates, disturbing the raw materials moving along the tank wall, thereby overcoming the shortcomings of the prior art.

[0008] Preferably, the inner wall of the feed shell is fixedly connected to an inclined plate for guiding the raw material to slide toward the spiked roller, and the inner wall of the feed shell is also fixedly connected to a baffle that covers the spiked roller to prevent excessive raw material from contacting it.

[0009] Preferably, a mounting plate is fixedly connected to the top of the mixing tank, an external motor is fixed to the top of the mounting plate by screws, and the spiked roller is driven by the output end of the external motor through a rotating shaft.

[0010] Preferably, the auxiliary mechanism further includes a connecting frame, and the scraper is fixed to the outer wall of the stirring rod through the connecting frame.

[0011] Preferably, the stirring structure further includes a heat dissipation shell, which is fixedly connected to the top of the mixing tank, and the output device is fixedly installed on the top of the inner wall of the heat dissipation shell.

[0012] Preferably, a sealing ring is rotatably connected to the top of the outer wall of the stirring rod, the sealing ring is engaged with the bottom of the outer wall of the output machine, and the sealing ring is fixedly connected to the top of the inner wall of the mixing tank.

[0013] Preferably, the front end of the mixing tank is provided with an auxiliary material port for adding auxiliary fillers, and the top of the mixing tank is provided with a feed port that communicates with the pre-dispersion mechanism.

[0014] Preferably, the bottom of the mixing tank is fixedly connected to a discharge plate for removing the mixed raw materials.

[0015] This utility model has the following beneficial effects: 1. This utility model solves the problem of insufficient mixing and uneven mixing caused by the direct entry of clumped cotton raw materials into the mixing tank in the prior art by setting a pre-dispersion mechanism consisting of a spiked roller and a spiked plate at the feeding end of the mixing tank. This achieves the effect of effectively dispersing the raw materials before mixing, significantly improving the final mixing quality.

[0016] 2. This utility model solves the problem in the prior art where raw materials would adhere to the tank wall or clump again during mixing by setting a scraper on the stirring rod and a guide plate on the tank wall that cooperates with the outer groove of the scraper. This achieves the effect of mixing materials without dead corners and with high intensity disturbance, ensuring that the final product is highly uniform. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0020] Example: Please refer to Figures 1 to 8 This utility model provides a mixing device for cellulose ester cotton raw materials, which aims to solve the structural defects of cellulose ester cotton raw materials in the prior art, such as clumping, adhesion, and uneven mixing before and during mixing.

[0021] Please refer to Figure 1 and Figure 2 As shown, the cotton raw material mixing device includes a mixing tank 1, a pre-dispersion mechanism 4 and a stirring structure 6 disposed on the top of the mixing tank 1. The mixing tank 1 serves as the main container of the entire device, carrying and mixing the raw materials. The pre-dispersion mechanism 4 is used to perform preliminary treatment on the raw materials before they enter the mixing tank 1. The stirring structure 6 is used to drive the stirring rod 603 to mix the raw materials inside the mixing tank 1. In addition, the front end of the mixing tank 1 is provided with an auxiliary material port 2 for adding auxiliary fillers, the top end of the mixing tank 1 is provided with a feed port 3 that communicates with the pre-dispersion mechanism 4, and the bottom end of the mixing tank 1 is fixedly connected with a discharge plate 7 for removing the mixed raw materials.

[0022] Please refer to Figure 1 , Figure 3 and Figure 4A mounting plate 401 is fixedly connected to the top left side of the mixing tank 1. A feed shell 402 is also fixedly connected to the top of the mixing tank 1. The mounting plate 401 is used to fix an external motor. A rotating shaft 403 is rotatably connected to the left end of the feed shell 402 via a bearing. A spiked roller 404 is fixedly connected to the right end of the rotating shaft 403. The left and right ends of the spiked roller 404 are rotatably connected to the inner wall of the feed shell 402 via bearings. The output end of the external motor is rotatably connected to the inner wall of the rotating shaft 403, thereby driving the spiked roller 404 to rotate inside the feed shell 402. An inclined plate 405 is fixedly connected to the front end of the inner wall of the feed shell 402, and the inclined plate 405 is used to guide the raw materials. The material slides into the rear end of the inner wall of the mounting plate 401 and contacts the spiked roller 404. The inner wall of the feed shell 402 is also fixedly connected to a baffle 406. The front end of the baffle 406 is located on the rear side of the top of the inclined plate 405, and the baffle 406 covers the spiked roller 404. The bottom end of the inner wall of the mounting plate 401 is fixedly connected to a spiked plate 407, which is located at the bottom end of the spiked roller 404. In the assembled state, a shearing gap is formed between the rotating spiked roller 404 and the stationary spiked plate 407. This structural combination ensures that the agglomerated raw materials are mechanically pulled and torn before entering the mixing tank 1, thereby achieving effective pre-dispersion.

[0023] Please refer to Figure 6 , Figure 7 and Figure 8 A heat dissipation shell 601 is fixedly connected to the top of the mixing tank 1. The top of the output machine 602 is fixedly connected to the top of the inner wall of the heat dissipation shell 601. The output end of the output machine 602 extends downward and is rotatably connected to a stirring rod 603. An auxiliary mechanism 5 is provided on the outer wall of the stirring rod 603. The auxiliary mechanism 5 includes a connecting frame 501 fixedly connected to the outer wall of the stirring rod 603, a scraper 502, a sealing ring 503, and a guide plate 504 fixedly connected to the inner wall of the mixing tank 1. Two connecting frames 501 are fixedly connected to the outer wall of the stirring rod 603. Scrapers 502 are fixedly connected to the left and right ends of the two connecting frames 501 respectively. The outer wall of the scraper 502 has an outer groove 505. The edge of the mixing tank 1 is dynamically fitted to the inner wall of the mixing tank 1. Multiple guide plates 504 are fixedly connected to the inner wall of the mixing tank 1. When the stirring rod 603 rotates, the guide plates 504 pass through the outer grooves 505 on the scraper 502. This dynamic interlocking structure of the scraper 502 and the guide plates 504 ensures that during the stirring process, not only can the material attached to the tank wall be continuously scraped off, but the overall circumferential motion of the material can also be continuously interrupted and disturbed, thereby effectively preventing the raw materials from sticking and clumping again. A sealing ring 503 is rotatably connected to the top of the outer wall of the stirring rod 603. The sealing ring 503 is engaged with the bottom of the outer wall of the output machine 602, and the sealing ring 503 is fixedly connected to the top of the inner wall of the mixing tank 1.

[0024] As a preferred embodiment, such as Figure 3 and Figure 4As shown, in order to better guide the raw materials and prevent the piercing roller 404 from jamming when processing large quantities of raw materials, an inclined plate 405 for guiding the raw materials to slide towards the piercing roller 404 is fixedly connected to the front end of the inner wall of the feed shell 402. At the same time, a baffle 406 is also fixedly connected to the inner wall of the feed shell 402. The front end of the baffle 406 is located on the rear side of the top of the inclined plate 405, and the baffle 406 covers the piercing roller 404. Through the cooperation of the inclined plate 405 and the baffle 406, the amount of raw materials entering the area of ​​the piercing roller 404 can be effectively controlled, avoiding instantaneous overload and ensuring the smoothness of the pre-dispersion process.

[0025] As another preferred implementation, such as Figure 1 As shown, in order to ensure that the spiked roller 404 in the pre-dispersion mechanism 4 can work stably and efficiently, a mounting plate 401 is fixedly connected to the top left side of the mixing tank 1. An external motor is fixed to the top of the mounting plate 401 by screws. The rotating shaft 403 is rotatably connected to the left end of the feed shell 402 through bearings. The left and right ends of the spiked roller 404 are rotatably connected to the inner wall of the spiked roller 404 through bearings. The output end of the external motor is rotatably connected to the inner wall of the rotating shaft 403 to form a transmission connection, so that the external motor can stably drive the rotating shaft 403 and the spiked roller 404 to rotate, ensuring the pre-dispersion effect. The mounting plate 401 provides a sturdy mounting platform for the external motor to prevent unstable shaking during operation.

[0026] As another preferred embodiment, such as Figure 5 and Figure 7 As shown, in order to enable the scraper 502 to form a stable connection with the stirring rod 603 and to effectively scrape the inner wall of the mixing tank 1, the auxiliary mechanism 5 also includes a connecting frame 501. The scraper 502 is fixed to the outer wall of the stirring rod 603 through the connecting frame 501. The connecting frame 501 provides sufficient mechanical strength and stability to ensure that the scraper 502 will not loosen or deform during the high-speed rotating stirring process and will continue to play its scraping role.

[0027] As another preferred implementation, such as Figure 5 As shown, in order to ensure that the output unit 602 of the driving stirring rod 603 can work continuously and stably without overheating during long-term operation of the mixing device, and to provide stable support for the output unit 602, the stirring structure 6 also includes a heat dissipation shell 601. The heat dissipation shell 601 is fixedly connected to the top of the mixing tank 1, and the top of the output unit 602 is fixedly installed on the top of the inner wall of the heat dissipation shell 601. The heat dissipation shell 601 not only provides a sturdy mounting base for the output unit 602, but also effectively dissipates the heat generated by the output unit 602 during operation through its own heat dissipation structure, preventing the temperature from being too high and affecting performance.

[0028] As another preferred implementation, such as Figure 5 and Figure 8As shown, in order to prevent water vapor or dust generated inside the mixing tank 1 from entering the interior of the output machine 602 during the mixing process, thus affecting normal operation and lifespan, a sealing ring 503 is rotatably connected to the top of the outer wall of the stirring rod 603. The sealing ring 503 is engaged with the bottom of the outer wall of the output machine 602, and the sealing ring 503 is fixedly connected to the top of the inner wall of the mixing tank 1. The sealing ring 503 forms an effective physical barrier, isolating the space between the interior of the mixing tank 1 and the output machine 602, effectively protecting the internal components of the output machine 602.

[0029] As another preferred implementation, such as Figure 1 As shown, in order to enable the batch or simultaneous addition of multiple raw materials and to provide a separate entry channel for the main raw material, the front end of the mixing tank 1 is provided with an auxiliary material port 2 for adding auxiliary fillers, and the top of the mixing tank 1 is provided with a feed port 3 that is connected to the pre-dispersion mechanism 4. The auxiliary material port 2 and the feed port 3 provide independent feeding paths, which increases the flexibility of operation and helps to achieve accurate batching.

[0030] As another preferred implementation, such as Figure 1 As shown, in order to facilitate the efficient and safe removal of the uniformly mixed raw materials by the staff, the bottom of the mixing tank 1 is fixedly connected to a discharge plate 7 for removing the mixed raw materials. The design of the discharge plate 7 allows the mixed raw materials to be smoothly discharged from the bottom of the mixing tank 1, reducing the difficulty and time of manual operation.

[0031] Working principle: When it is necessary to stir the raw material of cellulose ester cotton, the main raw material to be mixed is first added from the feed shell 402. When the raw material enters the feed shell 402, it slides along the inclined plate 405 and contacts the licker roller 404. The external motor drives the rotating shaft 403 to drive the licker roller 404 to rotate at high speed. During the rotation of the licker roller 404, a shearing gap is formed with the licker plate 407 located below, which strongly pulls and tears the raw material. The baffle 406 controls the amount of raw material entering and prevents the licker roller 404 from being stuck by a large amount of raw material. Through the synergistic effect of the licker roller 404 and the licker plate 407, the clump of cellulose ester cotton raw material is effectively dispersed, and the initial dispersion treatment is achieved, avoiding the problem of uneven mixing caused by the raw material directly entering the mixing tank 1. The dispersed raw material enters the interior of the mixing tank 1 through the feed port 3. Simultaneously, auxiliary filler enters the interior of mixing tank 1 through auxiliary material inlet 2 at the front end of mixing tank 1 and merges with the main raw material. At this time, stirring structure 6 is activated, and output motor 602 inside heat dissipation shell 601 starts working. Output motor 602 drives stirring rod 603 to rotate. The rotation of stirring rod 603 drives connecting frame 501 and scraper 502 fixed to the outer wall to perform circumferential motion inside mixing tank 1. The edge of scraper 502 maintains dynamic contact with the inner wall of mixing tank 1. During the stirring process, scraper 502 continuously scrapes off the raw material adhering to the inner wall of mixing tank 1, ensuring that all materials can participate in the mixing and avoid... This avoids the residue and waste of raw materials. At the same time, the guide plate 504, which is fixedly connected to the inner wall of the mixing tank 1, continuously passes through the outer groove 505 on the outer wall of the scraper 502 when the stirring rod 603 and scraper 502 rotate. The guide plate 504 creates continuous disturbance and impact on the mixing raw materials that are undergoing circular motion. This dynamic interlacing structure effectively destroys the laminar flow state and agglomeration tendency of the raw materials, forces the materials to be fully mixed in three dimensions, and prevents the raw materials from forming clumps or layers again due to centrifugal force or their own viscosity during the stirring process, thereby greatly improving the uniformity and thoroughness of mixing. Throughout the mixing process, the sealing ring 503, which is rotatably connected to the top of the outer wall of the stirring rod 603, engages with the bottom of the outer wall of the output machine 602 and is fixedly connected to the top of the inner wall of the mixing tank 1, forming an effective sealing barrier. This prevents water vapor and dust generated inside the mixing tank 1 from entering the output machine 602, thus protecting the normal operation and service life of the output machine 602. Meanwhile, the heat dissipation shell 601 continuously dissipates heat for the output machine 602, ensuring stability during long-term operation. After the mixing operation is completed, the discharge plate 7 fixedly connected to the bottom of the mixing tank 1 makes it convenient for the staff to take out the uniformly mixed cotton raw material. The whole device achieves efficient and uniform mixing of cotton raw material from dispersing before feeding to mixing process through the synergistic action of the pre-dispersion mechanism 4, the stirring structure 6 and the auxiliary mechanism 5. It fundamentally solves the problem of cotton raw material clumping and uneven mixing in the existing technology, and significantly improves the mixing quality and production efficiency.
