Description

Technical Field

[0001] This utility model relates to the field of pill screening equipment technology, and in particular to a pill screening device. Background Technology

[0002] During the manufacturing process of pills, due to inherent errors, the size of the pills may vary. The size of the pills determines the dosage, which significantly impacts the patient's recovery. Therefore, the size of the pills needs to be controlled within a reasonable range. Pills that are too large can cause adverse reactions, while pills that are too small will not achieve the desired therapeutic effect. To achieve this, current technology often uses pill screening equipment to select the appropriate pills.

[0003] Currently, pellet screening equipment typically includes spiral pellet separators and linear pellet screens. Linear pellet screens usually include a multi-stage screening mechanism capable of reciprocating motion. By setting the screen aperture space to decrease from top to bottom and enabling reciprocating motion, pellets of appropriate size can be screened out. However, this existing technology also has some shortcomings. For example, because pellets have a certain degree of viscosity, some standard pellets may adhere and become solid particles during screening, preventing them from entering the lower screening stages and ultimately being transported to the waste bin, resulting in waste.

[0004] Therefore, a pellet screening device that can break down and prevent pellets from sticking together needs to be designed. Utility Model Content

[0005] The purpose of this invention is to address the deficiencies and shortcomings of the existing technology by providing a pill screening device that solves at least one of the aforementioned technical problems. It has the advantages of being able to disperse and prevent pills from sticking together.

[0006] To achieve the above objectives, this utility model provides a pellet sieving device, comprising: a linear pellet sieving device and a pellet blocking device; the linear pellet sieving device includes a first sieving mechanism, a second sieving mechanism and a fourth sieving mechanism arranged sequentially from top to bottom, wherein one end of the first sieving mechanism is a feeding end and the other end has a first discharge port; the pellet blocking device is disposed between the feeding end and the first discharge port, near the first discharge port, for laterally blocking and separating the bonded pellets.

The shot blocker includes a crossbar and comb teeth. The two ends of the crossbar are respectively connected to one of the long frame pieces and are arranged to intersect with the two long frame pieces. A plurality of comb teeth are vertically arranged on the crossbar.

[0008] Optionally, the shot sieve blocker is configured at a right angle to the long frame.

[0009] Optionally, the distance between the comb teeth is greater than the outer diameter of a standard pill but less than twice the outer diameter of a standard pill.

[0011] Optionally, the distance between the shot sieve blocker and the first discharge port is equal to 1 / 3 of the length of the long frame.

[0012] Optionally, the linear shot sieving machine further includes a third screening mechanism located between the second screening mechanism and the fourth screening mechanism; the bottom of the second screening mechanism has a second screen, the bottom of the third screening mechanism has a third screen, and the bottom of the fourth screening mechanism has a fourth screen; and the aperture of the first screening mechanism is larger than the aperture of the second screening mechanism, the aperture of the second screening mechanism is larger than the aperture of the third screening mechanism, and the aperture of the third screening mechanism is larger than the aperture of the fourth screening mechanism.

[0015] Optionally, the pill screening device further includes a feeding mechanism located near the feeding end of the linear pellet screener. The feeding mechanism has a feeding port on the upper side of the feeding end, and the size of the feeding port is adjustable.

[0016] Compared with the prior art, the advantages of this application are:

[0017] This pellet screening device features a transversely positioned pellet stopper between the feeding end and the first discharge port, near the first discharge port, to block and separate adhered pellets.

[0037] 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.

[0038] It should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," "back," "side," and "circumferential" used in this utility model indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are only used to distinguish multiple components or structures with the same or similar structures, and do not indicate any special limitation on the arrangement order or connection relationship.

[0039] Please refer to Figures 1 to 5 This utility model provides a pill screening device 1000 for screening out standard pills. The pill screening device 1000 includes: a linear pill screening device 100 and a pill blocking device 200.

[0040] The linear shot sieving device 100 includes a first screening mechanism 1, a second screening mechanism 2, and a fourth screening mechanism 4. These three mechanisms are arranged sequentially from top to bottom. One end of the first screening mechanism 1 is the feeding end a, and the other end has a first discharge port b1. The linear shot sieving device 100 is a shot sieve capable of reciprocating linear motion in a straight line. This causes the shot to be subjected to a certain amount of throwing and impact, allowing the material particles to be stratified and sieved according to their size, and to move from the feeding end a to the first discharge port b1. Since the first screening mechanism 1, the second screening mechanism 2, and the fourth screening mechanism 4 all perform reciprocating linear motion, standard shot, shot heads larger than the standard shot, and shot particles smaller than the standard shot can be screened out. A shot sieve blocker 200 is positioned between the feeding end a and the first discharge port b1, close to the first discharge port b1, and serves to laterally block and separate adhered shot.

[0041] The pellet sieving device 1000 has a laterally positioned pellet stopper 200 between the feeding end a and the first discharge port b1, near the first discharge port b1, to block and separate the adhered pellets. Since the adhered pellets jump forward as they move towards the first discharge port b1, they collide with the laterally positioned pellet stopper 200, thus being broken into individual pellets. Furthermore, positioning the pellet stopper 200 between the feeding end a and the first discharge port b1, near the first discharge port b1, provides the necessary travel distance for the pellets, preventing them from becoming overly concentrated and clogging the pellet stopper 200, further improving the dispersing effect.

[0042] To achieve the purpose of lateral blocking and separation of the binding pellets, optionally, please refer to... Figure 3 and Figure 4 In this embodiment, the first screening mechanism 1 includes a screen frame 11 and a first screen 12 located at the bottom of the screen frame 11. The screen frame 11 includes two long side frames 111 and two short side frames 112. The long side frames 111 are arranged from the feeding end a to the first discharge port b1, and the short side frames 112 connect the ends of the two long side frames 111. The shot blocker 200 includes a crossbar 210 and comb teeth 220. The two ends of the crossbar 210 are respectively connected to a long side frame 111 and intersect with the two long side frames 111. Multiple comb teeth 220 are vertically arranged on the crossbar 210. In this way, the adhesive shot jumping towards the first discharge port b1 will hit the comb teeth 220 of the shot blocker 200 and be separated and dispersed.

[0043] Alternatively, please refer to Figure 2In this embodiment, the shot sieve blocker 200 is configured at a right angle to the long frame 111. Of course, in other embodiments, the shot sieve blocker 200 may also be configured at other angles to the long frame 111, as long as it can achieve lateral dispersion and separation of the bonded shot. The number of shot sieve blocks 200 is not limited to one; multiple blocks may be spaced apart along the length of the straight shot sieve device 100, and no specific limitation is made here.

[0044] Alternatively, please refer to Figure 3 In this embodiment, the distance between the comb teeth 220 is greater than the outer diameter of a standard pellet but less than twice the outer diameter of a standard pellet. This further improves the effect of breaking down and separating the sticky pellets.

[0045] Alternatively, please refer to Figure 2 In this embodiment, the distance between the shot sieve blocker 200 and the first discharge port b1 is equal to 1 / 3 of the length of the long frame 111. Of course, in other embodiments, the distance between the shot sieve blocker 200 and the first discharge port b1 can also be equal to 1 / 4 or 1 / 2 of the length of the long frame 111. As long as the distance between the shot sieve blocker 200 and the first discharge port b1 is greater than or equal to 1 / 4 of the length of the long frame 111 and less than or equal to 1 / 2 of the length of the long frame 111, it is acceptable.

[0046] To further classify pills smaller than the standard pill size, and to process the screened non-standard pills differently to improve pill utilization, optionally, please refer to... Figure 4 In this embodiment, the linear sieve pellet device 100 further includes a third sieving mechanism 3, which is located between the second sieve mechanism 2 and the fourth sieve mechanism 4. The bottom of the second sieve mechanism 2 has a second screen 21, the bottom of the third sieve mechanism 3 has a third screen 31, and the bottom of the fourth sieve mechanism 4 has a fourth screen 41. Furthermore, the aperture of the first sieve mechanism 1 is larger than that of the second sieve mechanism 2, the aperture of the second sieve mechanism 2 is larger than that of the third sieve mechanism 3, and the aperture of the third sieve mechanism 3 is larger than that of the fourth sieve mechanism 4.

[0047] To further enhance the automation of the pill screening device 1000, optionally, please refer to... Figure 1 and Figure 5In this embodiment, the first discharge port b1 is connected to a first guide member 13 for conveying the pills to the first collection tank 51; the second screening mechanism 2 has a second discharge port b2 at the end away from the feeding end a, and the second discharge port b2 is connected to a second guide member 22 for conveying the pills to the second collection tank 52; the third screening mechanism 3 has a third discharge port b3 at the end away from the feeding end a, and the third discharge port b3 is connected to a third guide member 32 for conveying the pills to the third collection tank 53; the fourth screening mechanism 4 has a fourth discharge port b4 at the end away from the feeding end a, and the fourth discharge port b4 is connected to a fourth guide member 42 for conveying the pills to the fourth collection tank 54.

[0048] To achieve the linear reciprocating motion of the linear shot sieve device 100, optionally, please refer to... Figure 4 and Figure 5 In this embodiment, the linear shot sieving device 100 further includes a base frame 7, a support frame 6, and a reciprocating drive device 8. The first screening mechanism 1, the second screening mechanism 2, the third screening mechanism 3, and the fourth screening mechanism 4 are sequentially arranged on the support frame 6 from top to bottom. The reciprocating drive device 8 is located on the side of the support frame 6 near the feeding end a and is connected to the support frame 6, used to drive the support frame 6 to perform reciprocating linear motion relative to the base frame 7. Optionally, the reciprocating drive device 8 includes a drive motor 81 and a reciprocating pump 82 driven by the drive motor 81. The output end of the reciprocating pump 82 is connected to the support frame 6, thus driving the support frame 6 and the first screening mechanism 1, the second screening mechanism 2, the third screening mechanism 3, and the fourth screening mechanism 4 mounted thereon to perform linear reciprocating motion relative to the base frame 7. Specifically, the reciprocating pump 82 is prior art and will not be elaborated upon here. Optionally, the long support rods on both sides of the upper end of the base frame 7 have connecting blocks 71, and the inner side of the connecting blocks 71 has a sliding groove c. The bottom of the fourth screening mechanism 4 is fixedly provided with a sliding rod 61 that slides in conjunction with the sliding groove c. This enables the first screening mechanism 1, the second screening mechanism 2, the third screening mechanism 3, and the fourth screening mechanism 4 to slide stably back and forth relative to the base frame 7 under the traction of the reciprocating drive device 8.
