Description

TECHNICAL FIELD

[0001] The utility model relates to pharmaceutical equipment technical field, specifically, relate to a coating machine that coating is even. BACKGROUND

[0002] In the production process of many industries, such as pharmaceutical, food processing, material coating is a key process, but the traditional coating machine has many problems and limitations to be solved.

[0003] Early coating equipment mostly adopts simple roller type structure, only relies on the rotation of the roller to make the material tumble inside, to realize the contact of coating liquid and material. However, this single tumbling mode makes the material mixing extremely uneven, and the material particles mostly only do simple rolling along the circumferential direction in the roller, the opportunity of contacting coating liquid of materials in different positions is quite different, and the phenomenon of part of the material surface coating too thick and another part coating too thin easily appears, which seriously affects the quality stability and appearance consistency of products. For example, in the pharmaceutical industry, uneven drug particle coating will lead to inconsistent drug release rate, affect the drug efficacy, and do not meet the strict quality standards of drug production.

[0004] Subsequently, some coating machines have improved the internal structure of the roller and added fixed baffles and other components, but these fixed baffles can only change the movement trajectory of the material to a certain extent and cannot be flexibly adjusted according to the characteristics of the material. For irregularly shaped and unevenly sized materials, fixed baffles are difficult to make them fully and uniformly mixed, and there are still problems of uneven coating effect, which limits the applicability of the equipment to different materials, so that enterprises need to equip multiple types of coating machines when facing diversified production materials, increasing the equipment procurement cost and the complexity of production management.

[0005] Moreover, the traditional coating machine performs poorly in the stability of material flow. Due to the lack of effective guidance and regulation mechanism, the movement of the material in the roller is disordered, and collisions and accumulation often occur, especially when the process parameters such as feed speed and coating liquid supply change slightly, the material flow will be in a chaotic state, which will lead to frequent interruption of the coating process, problems such as clogging of the nozzle and adhesion of the material to the inner wall of the roller, which seriously affects the production efficiency, increases the maintenance cost and downtime of the equipment, and cannot meet the dual requirements of yield and quality on large-scale and continuous production lines.

[0021] As a further technical solution, the first limiting part has a third accommodation groove, the second connecting part being rotatably and slidably arranged in the first connecting pipe, the third accommodation groove being used for guiding the second connecting part to slide into the first connecting pipe.

[0022] As a further technical solution, further comprising:

[0023] A liquid adding pipe is arranged on the frame and extends into the drum, and has a nozzle facing the drum wall.

[0024] As a further technical solution, further comprising:

[0025] A rotating driving member is arranged on the frame and used to drive the drum to rotate.

[0026] As a further technical solution, the coating baffle is a plurality of circumferentially arranged in the drum.

[0027] The working principle and beneficial effects of the present application are as follows:

[0028] In the present application, the coating baffle is arranged on the inner wall of the drum in an inclined manner, and when the drum rotates, the coating baffle can well stir the material in the drum. The material in the drum will continuously contact the coating baffle with the rotation, and since the coating baffle is inclined, the material will be lifted and slide along the inclined direction after hitting the baffle, changing the original movement track, so as to realize the full mixing of the material between different positions in the drum. This is crucial for the coating process, because only when the material is fully mixed, can it ensure that each material particle has an equal opportunity to contact the coating liquid, so that the coating liquid can uniformly wrap the surface of the material, avoiding the situation of local material coating too thick or too thin, improving the uniformity and quality of the coating, ensuring the consistency of the final product, and meeting the quality standard requirements of production.

[0029] The inclined baffle is arranged in a swinging manner relative to the coating baffle, further enhancing the mixing effect of the material. When the drum rotates and the material moves under the action of the coating baffle, the inclined baffle with the adjusted angle will produce additional stirring and stabilize the material, so that the material is more fully stirred under the action of the coating baffle. The swinging of the inclined baffle enables it to adjust different angles according to different materials, enhancing the versatility of the equipment, and the inclined baffle further improves the uniformity of the distribution of the coating liquid on the surface of the material, making the coating effect more ideal, especially for some irregular-shaped and uneven-sized materials. This cooperative stirring and mixing can better overcome the problem of uneven coating caused by the characteristics of the material itself.

[0030] The coating baffle and the inclined baffle jointly create a relatively stable material flow environment, which plays a key role in the continuous and stable operation of the equipment. They ensure that the material in the drum is not disorderedly colliding and piling up, but is turned over, mixed and moved forward (with the rotating direction of the drum) according to certain rules, which makes the spraying of the coating liquid, the coating of the material and the subsequent drying and other links in order, and the coating process will not be interrupted and blocked due to the disorderly flow of the material. Stable material flow ensures smooth work flow of the entire coating machine. No matter how the process parameters such as the feeding speed of the material and the supply amount of the coating liquid change, the equipment can rely on this stable material flow state to stably operate, continuously and efficiently complete the coating task, and meet the yield and quality requirements on the production line.

DETAILED DESCRIPTION

[0041] In order to more clearly illustrate the technical scheme in the embodiments of the utility model or the prior art, the specific implementation of the utility model will be described below with reference to the drawings. Obviously, the drawings described below are only some embodiments of the utility model, and other drawings and other implementation manners can be obtained by those skilled in the art without creating creative labor on the basis of these drawings.

[0042] In order to make the drawing simple, only the parts related to the utility model are schematically represented in each drawing, and they do not represent the actual structure of the product. In addition, in order to make the drawing simple and easy to understand, in some drawings, only one of the parts with the same structure or function is schematically represented, or only one of them is marked. In this paper, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0043] In this paper, it should be noted that, unless otherwise specified and limited, the terms "mounting", "connecting" and "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0044] In addition, in the description of the present application, the terms "first", "second" and the like are only used for differentiation and description, and cannot be understood as indicating or implying relative importance.

[0045] REFERENCE Figures 1-7 For the first embodiment of the utility model, a coating machine with uniform coating is proposed, which comprises a rack 1, a drum 2 rotatably arranged on the rack 1, a coating baffle 3 inclinedly arranged on the inner wall of the drum 2, and an inclined baffle 4 swingably arranged relative to the coating baffle 3.

[0046] In this embodiment, the coating baffle 3 is inclinedly arranged on the inner wall of the drum 2. When the drum 2 rotates, the coating baffle 3 can play a good tumbling effect on the material in the drum. The material in the drum will continuously contact the coating baffle 3 with the rotation. Since the coating baffle 3 is inclined, after the material hits the baffle, it will be carried up and slide down along the inclined direction, changing the original movement track, so as to realize the full mixing of the material in the drum at different positions. This is crucial for the coating process, because only the material is fully mixed, can ensure that each material particle has equal opportunity to contact the coating liquid, so that the coating liquid can uniformly wrap the surface of the material, avoid the local material coating too thick or too thin, improve the uniformity and quality of the coating, ensure the consistency of the final product, meet the quality standard requirements of production.

[0047] The inclined baffle 4 is arranged relative to the coating baffle 3 to further enhance the mixing effect of the material. When the drum rotates and the material moves under the action of the coating baffle 3, the inclined baffle 4 with the adjusted angle will produce additional agitation and stabilize the material, so that the material can be more fully stirred under the action of the coating baffle 3. The swinging of the inclined baffle 4 enables it to adjust different angles according to different materials, enhancing the versatility of the equipment. The inclined baffle 4 further improves the uniformity of the coating liquid distribution on the surface of the material, making the coating effect more ideal, especially for some irregular-shaped and uneven-sized materials. This cooperative tumbling mixing can better overcome the problem of uneven coating caused by the characteristics of the material itself.

[0048] The combined action of the coating baffle 3 and the inclined baffle 4 enables the material in the drum 2 to present a multi-angle and diversified movement state. The material will not only roll along the circumferential direction of the drum, but also produce up and down, left and right displacement and tumbling under the influence of the inclination of the coating baffle 3 and the swinging of the inclined baffle 4. This enables the coating liquid to contact the material particles from all directions, achieving all-around wrapping of the material. Whether it is the top, bottom or side of the material particle, there is an equal opportunity to be covered by the coating liquid, thereby ensuring the high uniformity of the coating and improving the overall quality of the product. For example, when coating candies in the food industry, the coating color and thickness on the surface of the candy can be uniform, and the appearance is more beautiful, meeting the expectations of consumers for product appearance and quality.

[0049] The coating baffle 3 and the inclined baffle 4 jointly create a relatively stable material flow environment, which plays a key role in the continuous and stable operation of the equipment. They ensure that the material in the drum is not disorderedly colliding and piling up, but is turned over, mixed and moved forward (with the drum rotating direction), which makes the spraying of the coating liquid, the coating of the material and the subsequent drying and other links can be orderly connected, and the coating process will not be interrupted and blocked due to the disorderly flow of the material. Stable material flow ensures smooth work flow of the entire coating machine. No matter how the process parameters such as the feeding speed of the material and the supply amount of the coating liquid change, the equipment can rely on this stable material flow state to stably operate, continuously and efficiently complete the coating task, and meet the yield and quality requirements of the production line.

[0050] Further, the first connecting piece 5 is provided on the coating baffle 3, the first connecting piece 5 has a first connecting pipe 501, the second connecting piece 6 has a second connecting part 601 and a fixing part 602, the fixing part 602 is provided on the inclined baffle 4, and the second connecting part 601 is rotationally arranged in the first connecting pipe 501.

[0051] In the embodiment, the installation process of the first connecting piece 5 and the second connecting piece 6 is relatively simple during the equipment installation stage. The construction personnel only need to insert the second connecting part 601 into the first connecting pipe 501 to realize installation, the entire operation steps are clear and understandable, no complex tools or special installation process is needed, the connection work between the coating baffle 3 and the inclined baffle 4 can be quickly completed, the efficiency of on-site installation is improved, and the labor cost investment is reduced. Moreover, this clear installation method is easy for construction personnel with different experience levels to master, ensures the consistency of installation quality, is conducive to ensuring the subsequent stable and reliable operation of the equipment, shortens the installation period of the entire coating machine, makes it put into use as soon as possible, and meets the production demand.

[0052] Further, the dustproof piece 8 is arranged at the end of the first connecting pipe 501 and is used for sealing the first connecting pipe 501.

[0053] In this embodiment, the dustproof member 8 is arranged at the end of the first connecting pipe 501 to seal the first connecting pipe 501, which can effectively block the dust from the outside into the pipe. In the production environment, especially in some industrial production workshops, there are often a lot of dust particles. If these dusts enter the first connecting pipe 501, they may gradually accumulate in the pipe and the components connected thereto along with the operation of the equipment. Over time, not only will it affect the smoothness of the connection structure between the first connecting member 5 and the second connecting member 6, such as causing the movement of the clamping member 7 and other components to be blocked, but it may also mix into the material being coated, affecting the purity of the material, and thus adversely affecting the coating quality, such as causing impurities on the coating surface, uneven color, and other problems. The sealing effect of the dustproof member 8 can ensure that the inside of the first connecting pipe 501 always maintains a relatively clean environment, maintains the normal operation of each component, and ensures the smooth progress of the coating process and the stability of the quality of the coated products.

[0054] For the material in the coating machine, the dustproof member 8 plays an important protective role. In the coating process, the material needs to be in full contact with the coating liquid and evenly wrapped, and any foreign dust impurities may destroy this delicate process. By sealing the first connecting pipe 501, the dustproof member 8 prevents dust from entering the drum 2 from the connecting part and mixing with the material, so that the material can complete the coating operation in a relatively pure environment, ensuring the uniformity, integrity, and cleanliness of the material surface coating, improving the overall quality of the product, meeting the high-quality requirements of different industries for coated products, whether it is a pharmaceutical, food, or other products that need to be coated, the existence of the dustproof member 8 can reduce the quality problems caused by dust pollution, and improve the competitiveness of the product in the market.

[0055] Further, the first connecting pipe 501 has a first limiting portion 502, and the first limiting portion 502 is arranged in a plurality of rows. Between two adjacent first limiting portions 502, a first limiting groove 503 is formed. The second connecting member 6 has a second limiting portion 604, and the second limiting portion 604 is arranged in a plurality of rows. Between two adjacent second limiting portions 604, a second limiting groove 605 is formed, and the second limiting groove 605 is used to accommodate the first limiting portion 502, and the first limiting groove 503 is used to accommodate the second limiting portion 604.

[0056] In this embodiment, the mutual accommodation and cooperation of the first limiting part 502 and the second limiting groove 605, and the second limiting part 604 and the first limiting groove 503 greatly enhances the stability of the connection between the first connecting piece 5 and the second connecting piece 6. During the operation of the coating machine, the drum 2 continuously rotates, and the coating baffle 3 and the inclined baffle 4 will be subjected to the impact force of the material and the external force caused by the vibration of the equipment. If the connection between the two only relies on the conventional way of simple sleeving, it is easy to cause relative displacement, loosening and other situations, which affects the effect of their cooperative work, and further adversely affects the tumbling and uniformity of the material. Through this limiting structure, the first limiting part 502 is clamped into the second limiting groove 605, and the second limiting part 604 is clamped into the first limiting groove 503, which limits the relative movement between the two connecting pieces in multiple directions, so that they can be firmly fixed together, effectively resist various external forces, and ensure that the coating baffle 3 and the inclined baffle 4 always maintain the correct relative position, continuously and stably play a role in fully tumbling and uniform coating of the material, improve the reliability of the equipment operation, and prolong the service life of the equipment.

[0057] The arrangement of the plurality of first limiting parts 502 and second limiting parts 604 allows the external force to be evenly distributed to the entire connecting part through these limiting structures. When subjected to force from the material or the operation of the equipment, these forces will not be concentrated in a certain point or a local area, but will be transmitted and dispersed along the contact parts of each limiting part and limiting groove, avoiding the problem of stress concentration leading to damage of the connecting parts. This uniform stress characteristic further enhances the strength of the connecting structure, making it better able to cope with complex and variable external forces, whether from the impact force of the material, the vibration force of the equipment operation or other possible external force interference. It can ensure that the connecting part is intact, maintain the stable cooperative working relationship between the coating baffle 3 and the inclined baffle 4, ensure the stable operation of the coating machine, and continuously play its good coating function.

[0058] In the equipment installation stage, the first limiting part 502 and the second limiting part 604 and the corresponding limiting groove structure provide clear positioning guidance for the installation of the first connecting piece 5 and the second connecting piece 6. The construction personnel only need to align the first limiting part 502 with the second limiting groove 605, and at the same time align the second limiting part 604 with the first limiting groove 503, and then gently push or rotate, so that the two connecting pieces can be accurately assembled together. The whole operation process is simple and intuitive, and does not need complex debugging or repeated position adjustment, greatly improving the accuracy and efficiency of installation, reducing the installation time and labor cost investment. Moreover, this clear installation method is easy for construction personnel of different experience levels to master, ensuring the consistency of installation quality, which is conducive to ensuring the stable and reliable operation of the equipment afterwards, shortening the installation period of the whole coating machine, so that it can be put into use as soon as possible to meet the production demand.

[0059] Further, the first limiting part 502 has a first displacement slot 504, and the second limiting part 604 has a second displacement slot 606, and after the second connecting piece 6 is rotated, the first displacement slot 504 and the second displacement slot 606 are in communication or cancel the communication, and further comprising a locking piece 9, the locking piece 9 is simultaneously slidably arranged in the first displacement slot 504 and the second displacement slot 606, and is used for locking the relative position of the first limiting part 502 and the second limiting part 604.

[0060] In the embodiment, the locking piece 9 is simultaneously slidably arranged in the first displacement slot 504 and the second displacement slot 606, and can effectively lock the relative position of the first limiting part 502 and the second limiting part 604. In the running process of the coating machine, under the action of external forces such as vibration and impact force generated by continuous rotation of the drum and continuous turning of the material, only relying on the cooperation of the limiting part and the limiting groove can limit the relative movement between the connecting pieces to a certain extent, but there may still be a small risk of loosening. The existence of the locking piece 9 is like a "safety lock", which is clamped in the first displacement slot 504 and the second displacement slot 606 in communication, further reinforcing the connection between the first connecting piece 5 and the second connecting piece 6, so that it can more stably resist various external forces, ensure that the coating baffle 3 and the inclined baffle 4 always maintain accurate and stable relative positions, protect the cooperation of the two from external interference, and continuously provide protection for the uniform turning of the material and good coating effect, greatly improving the reliability of the equipment operation, prolonging the service life of the equipment, and especially suitable for long-time and high-intensity coating operation scenes, such as large-scale pharmaceutical or food coating production processes.

[0061] When subjected to external force, the cooperation of the locking piece 9 with the first and second displacement grooves 504, 606 can optimize the stress distribution of the connection site. The external force will be transmitted through the locking piece 9 and dispersed to each displacement groove and the limiting part and limiting groove structure connected thereto, avoiding the situation that stress is concentrated in a certain place causing damage to the component. This uniform stress characteristic further enhances the strength of the entire connection structure, making the connection between the first and second connecting pieces 5, 6 more secure, and better able to cope with complex and variable external forces, whether from the impact of materials, the vibration of equipment operation, or other unexpected external force interference, to ensure that the connection structure is intact, maintains the stable cooperation of each part of the coating machine, ensures the continuous and stable operation of the coating machine, and plays a good coating function to ensure that the product quality meets the standard requirements.

[0062] The design of the displacement groove communication and the locking piece 9 also provides convenience during the installation and maintenance of the equipment. During installation, the construction personnel can first preliminarily align and insert the first and second limiting parts 502, 604 into the limiting groove, and then rotate the second connecting piece 6 according to actual needs to complete the final stable connection by inserting the displacement groove into the locking piece 9. The operation steps are clear and flexible, and it is convenient to make fine adjustments according to the actual situation on site to ensure the accuracy and stability of the installation. When maintaining and repairing, if the connecting pieces need to be disassembled, only the locking piece 9 needs to be removed, and the second connecting piece 6 is rotated in the opposite direction to cancel the communication of the displacement groove, so that the two connecting pieces can be easily separated, facilitating the inspection, repair or replacement of the coating baffle 3, the inclined baffle 4 and their connecting parts. Without a complex disassembly process, the maintenance difficulty and workload are greatly reduced, the repair time is shortened, the impact on the normal use of the equipment is reduced, the maintainability and usability of the equipment are improved, the continuity of the coating process in production is ensured, and production delays and economic losses caused by equipment failure are avoided.

[0063] Further, the first limiting part 502 has a third displacement groove 505, and the second connecting part 601 is rotatably and slidably arranged in the first connecting pipe 501, and the third displacement groove 505 is used for guiding the second connecting part 601 to slide into the first connecting pipe 501.

[0064] The third accommodation slot 505 provided on the first limiting part 502 provides a clear guiding effect for the second connecting part 601 sliding into the first connecting pipe 501. During the equipment installation stage, when the construction personnel assembles the second connecting part 601 with the first connecting pipe 501, they only need to follow the direction indicated by the third accommodation slot 505, and then the second connecting part 601 can be easily and accurately inserted into the first connecting pipe 501, avoiding the situation that multiple attempts and repeated adjustments may occur due to the unclear insertion direction. This precise guiding function greatly simplifies the installation operation steps, significantly improves the installation efficiency, reduces the time and labor cost investment during the installation process, enables the installation work to be completed more quickly, shortens the installation cycle of the coating machine, enables it to be put into use as soon as possible, meets the production demand, and especially when a batch of coating machines are installed or the production workshop is updated and modified, this advantage can play a greater role.

[0065] The existence of the third accommodation slot 505 makes the installation operation more intuitive and simple, and is easy to master by construction personnel with different experience levels. Whether it is an experienced skilled worker or a novice who is installing such equipment for the first time, they can clearly know how to perform the connection operation of the parts according to the third accommodation slot 505, thereby ensuring the accuracy and standardization of the installation process and guaranteeing the consistency of the installation quality. This is conducive to the stable and reliable operation of the equipment afterwards, reduces the potential equipment failure caused by improper installation, lays a good foundation for the coating machine to continuously and stably perform the coating function in the long-term use process, and improves the overall reliability and durability of the equipment.

[0066] Through the guidance of the third accommodation slot 505, the second connecting part 601 can be accurately and correctly slid into the first connecting pipe 501 and reach the predetermined correct position, which is crucial to ensuring the stability of the connection between the first connecting part 5 and the second connecting part 6. During the operation of the coating machine, the drum 2 rotates continuously, and the violent tumbling of the material in the drum will generate continuous impact force and vibration force on the coating baffle 3 and the inclined baffle 4. If the position of the connecting parts is not accurate during the initial installation, it is easy to cause the connection structure to loosen and shift, thereby affecting the cooperative working effect of the two, destroying the normal tumbling and mixing state of the material, and adversely affecting the uniformity of the coating. The third accommodation slot 505 ensures the accurate assembly of the connecting parts, so that the first connecting part 5 and the second connecting part 6 can form a stable and reliable connection, effectively resist various external forces, maintain the good cooperation relationship between the coating baffle 3 and the inclined baffle 4, ensure the stable operation of the coating machine, improve the coating quality of the product, and prolong the service life of the equipment.

[0067] The third displacement slot 505 guides the process of sliding the second connecting part 601, which actually optimizes the force transmission path of the connecting part to a certain extent. When external force acts on the entire connecting structure, since the second connecting part 601 enters the first connecting pipe 501 along the reasonable path determined by the third displacement slot 505, the force can be more smoothly and uniformly transmitted and dispersed between the various connecting components, avoiding stress concentration in the local area due to uneven stress or unreasonable stress direction, thereby reducing the risk of damage (such as cracking, deformation, etc.) of the connecting components. The uniform stress characteristics further enhance the overall strength of the connecting structure, enabling it to better cope with complex and variable external force situations, whether from material impact, equipment operation vibration, or other unexpected external force interference, ensuring that the connecting part is intact, maintaining the stable cooperation of the coating machine components, ensuring the continuous and stable operation of the coating machine, and playing a good coating function to ensure that the product quality meets the standard requirements.

[0068] Further, the liquid adding pipe 10 is arranged on the frame 1 and extends into the drum 2, and the liquid adding pipe 10 has a spray port facing the drum wall of the drum 2.

[0069] In this embodiment, the spray port of the liquid adding pipe 10 faces the drum wall of the drum 2, which can make the coating liquid sprayed on the drum wall more evenly dispersed by the rotation of the drum and the tumbling of the material in the drum. When the coating liquid is sprayed onto the drum wall, it will form a liquid film with the rotation of the drum wall, and the material will contact these liquid films in turn during the continuous tumbling process. Compared with the situation that the coating liquid may be locally concentrated and unevenly covered when sprayed directly onto the material pile, this way of spraying onto the drum wall first and then contacting the material can make the coating liquid more evenly wrapped around the surface of each material particle. For example, in pharmaceutical coating production, different pills are used as materials, and through such a spraying method, it can ensure that each pill is evenly coated with coating liquid, ensuring the stability of the quality of the coated pills, and the performance of drug release is more uniform and consistent, improving the overall quality of the products and meeting the strict pharmaceutical quality standards.

[0070] Moreover, spraying towards the drum wall can also avoid the problem of material breakage caused by direct impact of the coating liquid on the material, especially for some materials with relatively fragile texture, such as some food particles or fragile pharmaceutical raw materials, etc. This spraying method is more gentle, protecting the integrity of the material, while achieving good coating effect, expanding the range of materials that the coating machine can handle, and making it suitable for the production needs of more types of products.

[0071] In combination with the tumbling action of the coating baffle 3 and the inclined baffle 4, the coating liquid sprayed on the cylinder wall can fully contact the material in a dynamic tumbling state. The coating baffle 3 makes the material constantly thrown up and slide down to change position, and the inclined baffle 4 further enhances the mixing effect of the material, while the coating liquid sprayed on the cylinder wall can meet the material at different times and positions, ensuring that each surface of the material has the opportunity to contact the coating liquid, realizing all-round coating. This makes the coating liquid play a more efficient role, reduces the waste of coating liquid, improves the efficiency and quality of coating, whether in appearance to make the product surface coating color uniform, thickness consistent, or in function to meet the specific protection, sustained-release and other needs of the product, better implementation can be achieved through this synergistic effect, enhancing the competitiveness of the product in the market.

[0072] Further, the rotating drive member 13 is provided on the rack 1 and used to drive the rotation of the drum 2.

[0073] In this embodiment, the rotating drive member 13 provides a reliable and stable power source for the rotation of the drum 2. During the operation of the coating machine, the drum 2 needs to rotate continuously and uniformly to drive the internal material to continuously tumble, so as to realize the full contact and uniform mixing of the material with the coating liquid, powder, core and other materials, and achieve the ideal coating effect. The rotating drive member 13 can output power according to the set rotation speed and torque, avoiding problems such as fluctuation and intermittent stop of the drum rotation speed caused by insufficient or unstable power, ensuring that the drum 2 can operate stably for a long time, meeting the needs of continuous and large-scale production, such as batch product coating processing in pharmaceutical factories and food factories, ensuring uninterrupted production process, improving production efficiency, and reducing the risk of production delay caused by equipment failure.

[0074] Moreover, the rotating drive member 13 usually has certain overload protection and other functions. When the drum 2 is subjected to unexpected large resistance (such as excessive accumulation of material, jamming between parts, etc.), it can automatically adjust or stop operation to prevent damage to the driving parts and the drum 2 itself due to overload, further ensuring the safety and stability of the equipment, prolonging the service life of the equipment, reducing maintenance costs and equipment replacement frequency.

[0075] Further, the coating baffle 3 is arranged in the drum 2 in a circumferential arrangement.

[0076] In this embodiment, a plurality of coating baffles 3 are circumferentially arranged in the drum 2, and when the drum 2 rotates, the material can be tumbled from various angles. No matter where the material is located in the drum, it will sequentially contact different positions of the coating baffles 3 during the rotation of the drum, be thrown up, slide down, or change direction, achieving full-range tumbling of the material in three-dimensional space. This full-range tumbling effect enables the material particles to mix sufficiently, and ensures that each material has an equal opportunity to contact the coating liquid sprayed from the liquid adding pipe 10, the powder added from the powder adding part 12, and the core pieces and other additives added through the additive part 11, thereby ensuring that the coating is evenly covered on the surface of the material, avoiding the situation that some materials are coated too thick or too thin, improving the overall quality of the coating, meeting the consistency requirements of appearance and performance of the product, and enabling the product to present better quality, whether it is a medicine, food, or other products that need to be coated.

[0077] The circumferential arrangement of the plurality of coating baffles 3 also helps to evenly disperse the accumulation of the material in the drum 2. Without enough and reasonably distributed tumbling components, the material is prone to accumulate in the local area of the drum, causing this part of the material to not fully participate in the coating process, affecting the overall coating effect. The circumferentially arranged coating baffles 3 can continuously disperse the accumulated material during the rotation of the drum, so that it is evenly distributed in the drum again, ensuring that the material can continuously and stably mix and coat with various additives, maintaining the smoothness of the material flow and coating operation in the coating machine, improving the working efficiency of the equipment, reducing the problems such as production interruption caused by material accumulation, and ensuring that the production process can be continuously and stably carried out.
