Description

Technical Field

[0001] The present invention relates to the technical field of pharmaceutical production, and particularly to an efficient screening device for raw materials in pharmaceutical production. Background Art

[0002] In the field of pharmaceutical production, the screening of raw materials is one of the key links to ensure the quality of drugs. Pharmaceutical production has strict requirements for indicators such as the particle size and purity of raw materials. An efficient and accurate raw material screening device can ensure that the raw materials entering the subsequent production process meet the standards, directly affecting the safety, effectiveness, and production efficiency of drugs. With the rapid development of the pharmaceutical industry, the requirements for the automation level, screening efficiency, and equipment stability of raw material screening are increasing day by day. Developing a screening device with both flexibility and reliability has become an important need in the industry.

[0003] Common pharmaceutical raw material screening devices on the market have certain limitations in actual applications. On the one hand, the screening angle of traditional screening equipment is usually fixed or the adjustment method is cumbersome, making it difficult to flexibly adjust according to the physical properties of different raw materials (such as particle density, humidity, particle size distribution, etc.). As a result, the movement trajectory and residence time of raw materials on the sieve plate are unreasonable. Some raw materials may accumulate due to improper screening angles or pass through the sieve holes too quickly, resulting in low screening efficiency or insufficient screening accuracy. On the other hand, the cleaning of the inner wall of the sieve box of existing equipment often relies on manual operation. It is necessary to frequently stop the machine and disassemble parts for cleaning, which not only increases the labor intensity and labor costs but also may cause damage to precision parts such as sieve meshes due to improper operation, affecting the service life of the equipment. At the same time, the untimely manual cleaning is likely to cause raw material residues, leading to the risk of cross-contamination and making it difficult to meet the hygiene specifications requirements of pharmaceutical production. Summary of the Invention

The scraping plate is connected to a bidirectional threaded rod through a traction assembly for controlling the sliding of the scraping plate.

[0008] A support frame, which is arranged on the outer wall of the sieve box. A storage chamber is fixedly connected to the middle end of the support frame. A slider is connected to the inner wall of the support frame through a moving assembly. The slider is connected to the bottom side of the storage chamber through a discharging assembly for controlling the feeding of raw materials.

[0009] Preferably, the traction assembly includes a winding roller fixedly connected to the middle end of the bidirectional threaded rod. A traction rope is arranged on the outer wall of the winding roller. One end of the traction rope is connected to the scraping plate. A guide wheel is arranged on the inner wall at the rear end of the sieve box. The traction rope is arranged on the outer wall of the guide wheel.

[0010] Preferably, the linkage assembly includes a sliding sleeve threadedly connected to the outer wall of the bidirectional threaded rod. A connecting rod is rotatably connected to the outer wall of the sliding sleeve. The bottom end of the connecting rod is rotatably connected to the bottom side of the rear side back plate.

[0011] Preferably, the moving assembly includes a third sliding rod fixedly connected to the inner wall of the support frame. A slider is slidably connected to the outer wall of the third sliding rod. A reciprocating lead screw is rotatably connected to the inner wall of the support frame. The rear end of the slider is sleeved on the outer wall of the reciprocating lead screw. A second driving motor is installed on the outer wall of the support frame through a fixing frame. The driving end of the second driving motor is fixedly connected to the outer wall of the reciprocating lead screw.

[0012] Preferably, the discharging assembly includes a diversion cover fixedly connected to the bottom side of the storage chamber. A telescopic hose is connected between the bottom end of the diversion cover and the slider.

[0013] Preferably, the screening assembly includes a sieve plate fixedly connected to the inner wall of the sieve box. A second discharging head is fixedly connected to the front end of the sieve plate.

[0014] Preferably, the elastic assembly includes a first sliding rod slidably connected to the outer wall of the first rotating block. A support rod is fixedly connected to the bottom end of the first sliding rod.

[0015] Preferably, springs are arranged on the outer walls of both the limiting rod and the first sliding rod.

[0016] Preferably, a first driving motor is installed on the outer wall of the fixed block through a fixing frame. The driving end of the first driving motor is fixedly connected to the outer wall of the bidirectional threaded rod.

[0017] Preferably, the bottom end of the telescopic hose is fixedly connected to a discharging port. A valve is arranged on the inner wall of the discharging port. A first discharging head is fixedly connected to the front end of the sieve box.

[0018] Working principle: First, start driving motor 1 to drive the bidirectional threaded rod to rotate, thereby controlling the sliding sleeve to move towards or away from each other on the outer wall of the bidirectional threaded rod. When the sliding sleeve moves, it will drive the connecting rod to rotate between the outer wall of the sliding sleeve and the bottom side of the rear back plate, thus driving the rear end of the rear back plate and the sieve box to rise, realizing the adjustment of the inclination angle of the sieve box. At the same time, the rotating bidirectional threaded rod will drive the winding roller to rotate. When the winding roller rotates, it winds the traction rope. The traction rope slides on the outer wall of the guide wheel, and then pulls the scraper to slide on the outer wall of the guide wheel, compressing the spring on the outer wall of the limiting rod. When the inclination angle of the sieve box is adjusted to the horizontal state, the winding roller releases the traction rope on its outer wall. At this time, the spring on the outer wall of the limiting rod resets, enabling the scraper to move on the inner wall of the sieve box, cleaning the inner wall of the sieve box, and pushing the raw materials remaining on the inner wall of the sieve box to the front end of the sieve box, facilitating cleaning from the discharge head 1. When the sieve box is inclined to a certain angle, start the vibration motor to make the sieve box and the sieve plate produce a vibration effect. Then start driving motor 2, which controls the reciprocating threaded rod to rotate, thereby enabling the slider to move reciprocally on the outer wall of the sliding rod 3. When the slider moves, it drives the discharge port inside it to move, and at the same time pulls the telescopic hose to expand and contract, evenly dropping the raw materials inside the storage chamber onto the top side of the sieve plate. After being screened by the sieve plate, the raw materials fall into the inner wall of the sieve box, and then flow out from the opening of the discharge head 1 due to gravity and the vibration effect, and other materials flow out from the opening of the discharge head 2, thus realizing the efficient screening of pharmaceutical raw materials.

[0019] The present invention provides a high-efficiency screening device for pharmaceutical production raw materials. It has the following beneficial effects:

[0020] 1. The present invention controls the rotation of the bidirectional threaded rod through driving motor 1, thereby adjusting the inclination angle of the sieve box. It can accurately adjust the screening angle according to the characteristics of different raw materials and screening requirements, making the movement trajectory and residence time of the raw materials on the sieve plate more reasonable, thus improving the screening efficiency. At the same time, starting the vibration motor makes the sieve box and the sieve plate produce vibrations, cooperating with the feeding of the raw materials and the reciprocating movement of the slider, enabling the raw materials to be evenly distributed on the sieve plate, and the vibration effect helps the raw materials to quickly pass through the sieve holes, further improving the screening quality, ensuring that the screened pharmaceutical raw materials meet the production standards, and providing high-quality raw material guarantee for the subsequent links of pharmaceutical production.

[0021] 2. The present invention has a cleaning mechanism composed of a scraper, a winding roller, a traction rope, a guide wheel, and a spring, etc. During the adjustment of the inclination angle of the sieve box, through the winding and releasing of the traction rope by the winding roller, and in cooperation with the resetting action of the spring, it can automatically control the movement of the scraper on the inner wall of the sieve box, realizing the automatic cleaning of the inner wall of the sieve box. There is no need for manual frequent entry into the equipment for cleaning, reducing the complexity and labor intensity of manual operation, reducing the labor cost, and at the same time avoiding the damage to the equipment that may be caused by manual cleaning, extending the service life of the equipment, and improving the operation stability and reliability of the equipment.
