Description
Technical Field
[0001] This utility model relates to the technical field of traditional Chinese medicine pill production equipment, and in particular to a pill screening machine with residual material recovery function. Background Technology
[0002] In the production of traditional Chinese medicine pills, pill screening is a crucial step in ensuring product specifications are consistent. In existing technologies, some pill screening equipment lacks a time control mechanism between the screen and the discharge port. This results in either excessively large pills being missed due to insufficient time spent in the screening process, or reduced efficiency due to excessive time spent in the screening process. Furthermore, unqualified pills are easily mixed with qualified products, and the remaining material is difficult to recover, leading to raw material waste. Therefore, a pill screening machine with a residual material recovery function is proposed to solve the above problems. Utility Model Content
[0003] To overcome the above deficiencies, this utility model provides a pill screening machine with residual material recovery function, which aims to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: A pill screening machine with residual material recycling function includes a frame, with support side plates fixedly installed on both the left and right sides of the frame. A vibration mechanism for providing vibration power is provided at the top of the two support side plates. A screening box is fixedly connected to the vibration mechanism. A screening mechanism for fine classification and screening of pills is provided inside the screening box. An anti-foreign object mechanism for intercepting metal foreign objects is provided inside the frame. The screening mechanism includes a first screen for intercepting oversized pills and sticky pills. The outer wall of the first screen is fixedly connected to the inner wall of the screening box. A discharge plate is fixedly connected to the left end of the first screen for discharging oversized pills and sticky pills. A switch assembly for controlling the discharge timing is provided between the first screen and the discharge plate. A second screen for intercepting undersized pills is fixedly connected to the bottom inner wall of the screening box. A discharge plate is fixedly connected to the left end of the screening box for discharging qualified products. The opening directions of the discharge plate and the discharge plate are opposite. As a further description of the above technical solution: The switching assembly includes two grooved plates for providing sliding guidance. The two grooved plates are respectively fixedly connected to the inner walls of the front and rear sides of the screening box. Baffles for controlling the discharge of the first screen are slidably installed on the inner walls of the two grooved plates. As a further description of the above technical solution: The bottom side of the baffle is in contact with the top side of the first screen, the first screen is located above the second screen, and the aperture of the first screen is larger than that of the second screen. As a further description of the above technical solution: The vibration mechanism includes four dampers, which are fixedly installed on the top of the two supporting side plates. The top of the two dampers on the right side is fixedly connected to a mounting plate, and a vibration motor is fixedly installed on the top of the mounting plate. As a further description of the above technical solution: The left end of the mounting plate is fixedly connected to the right end of the screening box, and the two dampers on the left side are fixedly connected to the bottom left side of the screening box. As a further description of the above technical solution: The foreign object prevention mechanism includes a collection hopper, which is fixedly connected inside the frame, and a discharge port is fixedly connected to the bottom of the collection hopper; As a further description of the above technical solution: Support plates are fixedly connected to the left and right sides of the discharge port, and metal adsorption plates are slidably installed on the inner walls of the adjacent side of the two support plates. As a further description of the above technical solution: The front side of the metal adsorption plate is provided with a limiting bending part, and the interior of the metal adsorption plate is provided with multiple through holes.
[0005] This utility model has the following beneficial effects: 1. In this utility model, the double-layer screen adopts a "larger at the top and smaller at the bottom" aperture design, which can accurately achieve three-level classification of "oversized / adherent pills - qualified pills - undersized pills". The switching component between the first screen and the discharge plate can adjust the residence time of the pills on the first screen through a sliding baffle. This avoids the leakage of oversized pills due to short residence time and prevents the screening efficiency from being affected by excessive residence time. At the same time, the intercepted oversized / adherent pills are discharged separately through the discharge plate and can be directly returned to the previous process for reprocessing, effectively reducing raw material waste and improving raw material utilization and screening efficiency.
[0006] 2. In this utility model, the conical collecting hopper receives debris, with a wider top and narrower bottom and a smooth inner wall to prevent accumulation, ensuring smooth sliding to the discharge port. The strong magnetic metal adsorption plate is installed through the support plate, which efficiently adsorbs impurities such as iron filings. The matrix through holes do not obstruct the passage of debris, and the 90° limiting bend prevents the adsorption plate from falling off. It also facilitates regular pulling and cleaning, avoiding the accumulation of impurities that may affect the adsorption or wear the equipment. Attached Figure Description

[0009] 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.
[0010] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a pill screening machine with residual material recovery function, including a frame 1 made of 304 stainless steel, with anti-slip pads at the four corners of the bottom. Support side plates 2 are fixedly installed on both the left and right sides of the frame 1. A vibration mechanism for providing vibration power is provided at the top of the two support side plates 2. A screening box 6 is fixedly connected to the vibration mechanism. The screening box 6 is a cuboid structure with an open top. The vibration mechanism includes four dampers 3, model XHS-5, which are fixedly installed at the top of the two support side plates 2. A mounting plate 4 is fixedly connected to the top of the two dampers 3 on the right side. A vibration motor 5 is fixedly installed at the top of the mounting plate 4. The mounting plate 4 is used to install and support the vibration motor 5. The left side of the mounting plate 4... The end is fixedly connected to the right end of the screening box 6 to transmit vibration power. The two dampers 3 on the left side are fixedly connected to the bottom left side of the screening box 6 to achieve symmetrical vibration support. The dampers 3 absorb the excess vibration energy transmitted to the screening box 6 by the vibration motor 5 to prevent the screening box from shaking too much, which would cause the pills to splash or the screening to shift. On the other hand, through symmetrical support, the screening box 6 is ensured to be subjected to balanced force when vibrating, preventing unilateral tilting and providing a stable vibration environment for graded screening. The screening box 6 is equipped with a screening mechanism for fine classification and screening of pills. After the vibration motor 5 is powered on, it outputs vibration power, which is directly transmitted to the screening box 6 through the mounting plate 4 to drive the screening box 6 to vibrate. The frame 1 is equipped with an anti-foreign object mechanism for intercepting metal foreign objects. The screening mechanism includes a first screen 7 for intercepting oversized pills and adhering pills. The outer wall of the first screen 7 is fixedly connected to the inner wall of the screening box 6. The left end of the first screen 7 is fixedly connected to a discharge plate 8 for discharging oversized pills and adhering pills. A switch assembly for controlling the discharge timing is provided between the first screen 7 and the discharge plate 8. The bottom inner wall of the screening box 6 is fixedly connected to a second screen 11 for intercepting oversized pills. The first screen 7 is located above the second screen 11, and the aperture of the first screen 7 is larger than that of the second screen 11 to achieve graded screening of the pills. The left end of the screening box 6 is fixedly connected to a discharge plate 12 for discharging qualified products, and the opening direction of the discharge plate 12 is opposite to that of the discharge plate 8. The switch assembly includes two grooved plates 9 for providing sliding guidance. The two grooved plates 9 are fixedly connected to the inner walls of the front and rear sides of the screening box 6, respectively. Baffles 10 for controlling the discharge of the first screen are slidably installed on the inner walls of the two grooved plates 9. The bottom side of the baffle 10 contacts the top side of the first screen 7 to achieve sealing and blocking.
[0011] Reference Figure 1 , Figure 2 and Figure 4 The foreign object prevention mechanism includes a collection hopper 13, which is a conical stainless steel structure used to collect debris and powder. The collection hopper 13 is fixedly connected to the inside of the frame 1. The bottom of the collection hopper 13 is fixedly connected to a discharge port 14, which is a rectangular stainless steel channel. Support plates 15 are fixedly connected to the left and right sides of the discharge port 14. Metal adsorption plates 16 are slidably installed on the inner wall of the adjacent side of the two support plates 15. The metal adsorption plates 16 are strong magnetic stainless steel plates to ensure that they can adsorb fine metal impurities (such as iron filings, steel slag, etc.). The front side of the metal adsorption plates 16 is provided with a limiting bending part, which is formed by bending the front side of the metal adsorption plates 16 upward by 90° to prevent the metal adsorption plates 16 from completely sliding out of the support plates 15. At the same time, the bending part is rounded to avoid scratching the operator. The interior of the metal adsorption plates 16 has multiple through holes, which are circular and arranged in a matrix to ensure that debris and powder can pass through smoothly without affecting the adsorption effect of metal impurities.
[0012] Working Principle: After the equipment is started, the vibration motor 5 in the vibration mechanism outputs power, which is transmitted to the screening box 6 through the mounting plate 4. At the same time, the four dampers 3 provide shock absorption and support for the screening box 6, ensuring the stability of the screening process. After the pellets to be screened enter the screening box 6, they first come into contact with the first screen 7 located above. Because the aperture of the first screen 7 is relatively large, it will intercept pellets that are too large or sticky, while pellets that meet the size requirements and are smaller will pass through the first screen 7 and fall down. The switching assembly between the first screen 7 and the discharge plate 8 can control the discharge timing. The sliding state of the baffle 10 within the grooved plate 9 can change the residence time of the pellets on the first screen 7, ensuring the interception effect. Oversized pellets and adhered pellets are eventually discharged through the discharge plate 8 for subsequent recycling. The pellets that pass through the first screen 7 fall to the second screen 11 below. The aperture of the second screen 11 is smaller than that of the first screen 7, which will intercept pellets that are too small. Only pellets of the qualified size can pass through the second screen 11 and be discharged through the discharge plate 12, which is opposite to the opening direction of the discharge plate 8, thus completing the grading and screening of the pellets and the separation of qualified products. During the screening process, the debris and powder passing through the second screen 11 will fall into the collection hopper 13 inside the frame 1 and slide down the collection hopper 13 to the discharge port 14 at the bottom. A metal adsorption plate 16 is slidably installed in the discharge port 14 through the support plate 15. When the debris and powder flow through the metal adsorption plate 16, the metal adsorption plate 16 will adsorb the mixed metal foreign objects, and the debris and powder can be smoothly discharged through the multiple through holes on the metal adsorption plate 16. In addition, the limiting bending part on the front side of the metal adsorption plate 16 makes it convenient for the operator to periodically pull out the metal adsorption plate 16 to clean the adsorbed metal foreign objects, ensuring that the anti-foreign object function is continuously effective and preventing metal foreign objects from being mixed into the subsequent waste treatment process or causing equipment damage.
[0013] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
