Description

Technical Field

[0001] This utility model relates to the field of production, specifically to an anti-sticking device for a Jinfengwan conveyor belt. Background Technology

[0002] In modern industrial production systems, conveyor belts, as core equipment for continuous material transport, are widely used in key areas such as food processing, pharmaceutical manufacturing, and chemical raw material transportation. Taking the production process of traditional Chinese medicine like Jinfeng Pills as an example, the conveyor belt is responsible for transporting the pills from the pill-making stage to subsequent processes such as coating and packaging. Its surface cleanliness and operational stability directly affect the uniformity of drug quality and the smoothness of the production line. However, when conveying materials with viscous or hygroscopic properties, the problem of conveyor belt surface adhesion has become a common challenge restricting production efficiency and product quality.

[0003] Traditional conveyor belts generally lack specialized anti-sticking structures in their design. This deficiency is particularly pronounced when used for conveying pharmaceuticals such as Jinfeng Pills. Firstly, powder or sticky components from the pill surface easily adhere to the conveyor belt, causing material waste, affecting dosage accuracy, and potentially contaminating the medicine due to microbial growth on the adhesive, thus violating production standards. Secondly, unremoved adhesive significantly increases conveyor belt resistance, leading to increased motor energy consumption, accelerated equipment wear, and even conveyor belt misalignment and slippage. Statistics show that downtime for cleaning and equipment maintenance due to adhesion problems can reduce production line efficiency and increase annual maintenance costs, becoming a significant bottleneck restricting the automation and intelligent upgrading of pharmaceutical production. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an anti-sticking device for Jinfeng pill conveyor belts. The design features a sloping structure at both ends of the frame, guiding the material smoothly with the help of gravity. A flexible silicone scraper at the front end closely adheres to the conveyor belt, effectively removing Jinfeng pills adhering to it through mechanical scraping. Circular grooves at the top of the frame have an inner diameter precisely designed according to the standard dimensions of Jinfeng pills, slightly larger than the pill's diameter. When the pills roll within the grooves, the inner wall of the grooves exerts uniform and moderate contact pressure, causing the pills, which may have been slightly deformed due to external pressure or transport bumps, to gradually regain their standard spherical shape as the surface force becomes more even during rolling, achieving automatic reshaping. Simultaneously, the circular grooves, combined with baffles on both sides with sliding grooves, form a stable guiding channel, ensuring that the pills do not roll off course during transport and providing a stable environment for the shaping process. Furthermore, the rotating frame and the fan frame are slidably connected via sliders and grooves, allowing for flexible adjustment of the fan's vertical height, horizontal position, and pitch angle. This ensures that the airflow generated by the fan precisely cleans the surface powder of the pills according to their actual condition. All components adopt a modular design, connected by bolts and nuts, enabling rapid assembly and disassembly and precise calibration. This design offers significant advantages: the ramps and scrapers work together to efficiently solve the problem of material adhesion and prevent drug contamination; the unique shaping function of the circular grooves effectively corrects shape defects without damaging the internal components of the pills, improving the appearance quality and consistency of the drugs and reducing the defect rate; the guiding and protective structure formed by the grooves and baffles stably transports the pills, providing reliable protection for the shaping process; the fan's flexible multi-angle adjustment function can meet the cleaning needs of different types of pills; and the modular bolt connection method facilitates equipment maintenance and cleaning, complies with pharmaceutical production standards, and provides strong support for the efficient operation of pharmaceutical production.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a Jinfengwan conveyor belt anti-sticking device, including a frame, the frame being a front and rear sloping type, the front end of the frame being a feed inlet and the rear end being a discharge outlet, the top of the frame having a plurality of circular grooves spaced apart, and the frame being provided with an anti-sticking device.

[0006] The anti-sticking device includes a scraper with baffles welded vertically to its left and right ends. T-shaped grooves are formed on the baffles, and a slider is installed inside the T-shaped grooves. Bolts are welded onto the sliders, which are connected to a rotating frame via bolts. A transverse groove is provided on the top surface of the rotating frame, and an adjusting bolt is installed inside the transverse groove. A fan frame is located below the groove, and a mounting hole is provided on the right side of the fan frame. The lower end of the adjusting bolt passes sequentially through the rotating frame, the transverse groove, and the mounting hole of the fan frame before being connected to an anti-loosening nut. A fan is embedded within the fan frame.

[0007] Furthermore, the T-shaped groove on the baffle extends in the front-to-back direction. The slider moves the rotating frame back and forth along the baffle by sliding with the T-shaped groove, thereby adjusting the front-to-back position of the rotating frame. At the same time, the pitch angle of the rotating frame can be adjusted by tightening or loosening the nut connected to the bolt on the slider.

[0008] Furthermore, the transverse sliding groove on the top surface of the rotating frame extends in the left-right direction. The adjusting bolt, through sliding engagement with the transverse sliding groove, drives the fan frame to move left and right along the rotating frame, thereby adjusting the left and right position of the fan. Loosening the anti-loosening nut at the bottom of the adjusting bolt allows the fan frame to rotate around the axis of the adjusting bolt, changing the angle between the fan frame and the rotating frame, thus adjusting the pitch angle of the fan.

[0009] Furthermore, a protrusion is provided at the bottom of the scraper, and a threaded hole is machined on the surface of the protrusion; a groove is opened at the corresponding position at the bottom of the frame, and the protrusion of the scraper is embedded in the groove of the frame. The scraper is tightened and fixed by bolts passing through the threaded hole of the protrusion, so as to achieve a stable connection between the scraper and the frame.

[0010] Furthermore, the wall of the circular groove at the top of the frame adopts a smooth arc transition design. When the Jinfeng ball rolls in the circular groove, the inner wall of the circular groove exerts uniform and moderate pressure on the Jinfeng ball.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0012] 1. Highly Efficient Anti-Stickiness and Cleanliness Guarantee: The flexible scraper at the front end closely adheres to the conveyor belt, precisely scraping away any adhering pills and eliminating pill residue. A multi-angle adjustable fan generates directional airflow to sweep the surface of the conveyed pills, removing any attached powder. Combined with the inclined design of the frame, this allows materials to flow smoothly, reducing the risk of stagnation and adhesion. This combination of mechanical scraping and airflow comprehensively prevents adhesion from the source to the process, ensuring a continuously clean conveyor belt, creating a hygienic environment that meets regulatory standards for pharmaceutical production, and avoiding quality problems caused by contamination.

[0013] 2. Enhanced Quality and Stable Delivery: The device achieves a dual improvement in drug quality and delivery performance through innovative structure. The circular groove at the top of the frame uses internal wall pressure to automatically reshape the rolling pills during delivery, effectively correcting minor deformations caused by external forces and ensuring the uniformity and consistency of the drug's appearance. Side baffles work in conjunction with the groove to form a stable guiding channel, preventing pills from shifting or rolling off. Furthermore, the modular bolted connection design facilitates quick disassembly and maintenance, ensuring long-term stable operation. From quality optimization to delivery assurance, this device provides solid support for drug production. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 In this embodiment, a Jinfengwan conveyor belt anti-sticking device includes a frame 1, which is sloping at the front and back. The front end of the frame 1 is a feed inlet 2, and the rear end is a discharge outlet 3. Multiple circular grooves 4 are distributed at intervals on the top of the frame 1, and an anti-sticking device 5 is provided on the frame 1.

[0020] The anti-sticking device 5 includes a scraper 501, with baffles 502 vertically welded to both ends of the scraper. A T-shaped groove 503 is formed on the baffle 502, and a slider 504 is provided inside the T-shaped groove 503. Bolts are welded to the slider 504, which is connected to a rotating frame 505 via bolts. A transverse groove 506 is provided on the top surface of the rotating frame 505, and an adjusting bolt 507 is provided inside the transverse groove 506. A fan frame 508 is provided below the groove 506, and a mounting hole is provided on the right side of the fan frame 508. The lower end of the adjusting bolt 507 passes sequentially through the rotating frame 505, the transverse groove 506, and the mounting hole of the fan frame 508 before being connected to an anti-loosening nut. A fan 509 is embedded within the fan frame 508.

[0021] A T-shaped groove 503 extends along the front-to-back direction on the baffle 502. The slider 504 is clearance-fitted with the T-shaped groove 503, and the rotating frame 505 is moved back and forth along the baffle 502 by sliding, achieving precise adjustment of the front-to-back position of the rotating frame 505. This design allows the rotating frame 505 to be flexibly adjusted to the optimal working area according to the specific distribution of the pills on the conveyor belt, ensuring that the airflow generated by the subsequent blower can effectively cover all the pills and improve the cleaning effect. At the same time, the nut bolted to the slider 504 can be tightened or loosened to change the tilt of the rotating frame 505, achieving flexible adjustment of the pitch angle. This adjustment method can change the direction and force of the airflow for pills of different sizes and shapes, ensuring the removal of powder while avoiding pills being blown off or damaged due to improper airflow. This greatly improves the adaptability and ease of operation of the device to different production needs, and reduces the difficulty and time cost of equipment debugging.

[0022] The top surface of the rotating frame 505 is provided with a transverse sliding groove 506 extending in the left-right direction. The adjusting bolt 507 slides in the transverse sliding groove 506. The displacement of the bolt in the sliding groove 506 drives the fan frame 508 to move laterally along the rotating frame 505, realizing precise adjustment of the left and right position of the fan 509. This structural design can accurately position the fan to a suitable transverse position according to the width of the conveyor belt and the arrangement of the pills, ensuring that the airflow coverage is perfectly matched with the material conveying area. At the same time, after loosening the anti-loosening nut at the bottom of the adjusting bolt 507, the fan frame 508 can rotate flexibly around the axis of the adjusting bolt 507, changing the angle between it and the rotating frame 505, thereby realizing free adjustment of the pitch angle of the fan 509. This adjustment method can precisely control the angle and force of the air blowing according to the size, shape characteristics and actual conveying speed of the pills, avoiding pill displacement or damage due to improper airflow direction and intensity, ensuring that the airflow can act on the surface of the pills in all directions without dead angles, effectively removing surface adhering materials, and significantly improving the cleaning effect and production applicability of the device.

[0023] The circular groove 4 at the top of the frame 1 features a smooth, rounded transition design. When the pills roll within the circular groove 4, the inner wall of the groove exerts uniform and moderate pressure on the pills. This causes the pills, which may have been slightly deformed by external forces, to automatically reshape into a standard spherical shape during rolling. Simultaneously, the smooth groove wall reduces frictional resistance between the pills and the groove, preventing damage to the pill surface and facilitating the removal of any powder adhering to the groove, thus ensuring consistent quality and cleanliness during the pill transport process.

[0024] The scraper end of scraper 501 has a thickness of 3-5mm and is made of silicone material. The contact angle between the bottom surface of the scraper end and the surface of the conveyor belt is 30°. The silicone scraper end can not only fit tightly with the surface of the conveyor belt to effectively remove the adhering pills and powder, but also avoid wear on the conveyor belt due to its high hardness.

[0025] In summary, the anti-sticking device for the Jinfeng Pill conveyor belt adopts a front and rear sloping design, combined with a top circular groove and side baffles, to create a guiding path for pill transport. The bottom protrusion of the scraper is interference-fitted with the groove of the frame and secured with bolts to achieve a stable connection, ensuring the continuous and reliable removal of adhering materials. The T-shaped chute and transverse chute in the anti-sticking device, along with the slider and adjusting bolts, give the rotating frame and the fan frame multi-dimensional adjustment capabilities in the front-back, left-right, and pitch directions, enabling precise control of the fan position and angle. Functionally, the scraper is responsible for mechanical scraping, and the fan blows through controlled airflow. The combination of the two eliminates the risk of pill adhesion from both physical contact and wind force. Furthermore, the circular groove can reshape the pills during transport, further ensuring the quality of the medicine.

[0026] This device possesses significant practical advantages and technological value. Firstly, its multi-dimensional adjustment structure significantly enhances equipment adaptability, allowing for flexible adjustment of the fan position and angle based on pill size, shape, and conveying speed. This ensures precise airflow onto the material surface, effectively removing powder and adhering substances, resulting in a substantial improvement in cleaning efficiency compared to traditional devices. Secondly, its modular and standardized design facilitates equipment maintenance. Components are connected by bolts, supporting rapid disassembly and replacement, significantly reducing downtime for maintenance and minimizing the risk of production interruptions. Thirdly, the automatic shaping function of the frame's circular grooves corrects pill shape defects without additional equipment, improving the consistency of drug appearance and yield. Through structural innovation and functional integration, this device effectively solves the adhesion problem in traditional conveying processes, providing a reliable guarantee for efficient, stable, and high-quality drug production.
