Description

Technical Field

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

[0002] Tablets typically refer to round tablets with slightly curved sides. During extrusion molding and conveying, tablets can be damaged by impact, resulting in defective tablets (hereinafter referred to as defective tablets) and powder. A tablet manufacturing defective product screening device is specifically designed to screen out defective tablets and then separately convey the qualified tablets.

[0003] For example, in the existing technology, there is a Chinese utility model patent with publication number CN223184945U entitled "A Screening Device for Defective Tablets in Pharmaceutical Production." This patent utilizes a vibrating motor to vibrate the screening frame, causing defective tablets to fall through the screen holes, thus achieving the effect of screening. While this screening device is suitable for removing broken tablets, it is difficult to remove relatively intact tablets with very few missing pieces. These tablets, if mixed into the finished product, affect product quality. Utility Model Content

[0004] The purpose of this invention is to provide a tablet fragment separation device in tablet production, which solves the problem that existing screening devices are suitable for screening out broken fragments, but it is difficult to screen out relatively complete fragments with very few missing pieces.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A tablet production residue separation device includes a horizontal channel, a transition channel, a vertical channel, and a negative pressure receiving mechanism. The horizontal channel, the transition channel, and the vertical channel are connected in sequence. The horizontal channel is provided with a first sieve outlet smaller than the diameter of a qualified tablet, and the vertical channel is provided with a second sieve outlet smaller than the thickness of the qualified tablet. The air inlet of the negative pressure receiving mechanism is connected to the first sieve outlet and the second sieve outlet, respectively.

[0006] A further technical solution is that the slide rail in the transverse channel is inclined, and the qualified tablet abuts against the bottom surface of the slide rail.

[0007] A further technical solution is: an elastic pressure strip is provided on the transverse channel, and the elastic pressure strip is pressed against the qualified tablet.

[0008] A further technical solution is that the first screen outlet consists of multiple strip-shaped holes with progressively increasing heights.

[0009] A further technical solution is that the first screening outlet is located at the bottom of the transverse channel.

[0010] A further technical solution is that the second screening outlet is located at the top of the vertical channel.

[0011] A further technical solution is: the negative pressure receiving mechanism includes a collection box, an air pipe and a negative pressure device, and multiple collection boxes are respectively installed on the first screen outlet and the second screen outlet, and the air inlet of the negative pressure device is connected to the air outlet of the collection box through the air pipe.

[0012] A further technical solution is that a filter screen is installed inside the collection box.

[0013] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: This invention proposes a tablet fragment separation device for tablet production. This device can screen out tablets with small defects, especially those missing from the periphery or sides, to prevent such fragments from mixing with qualified tablets and affecting the product quality of the tablets.

[0014] In addition, the negative pressure screening method avoids the dust generated by the traditional vibration tablet screening method, is environmentally friendly and low-noise, and avoids tablet loss caused by tablets colliding with each other due to vibration. Attached Figure Description

[0027] This implementation example Figure 2 As shown, the tablet fragment separation device in tablet production includes a horizontal channel 1, a transition channel 2, a vertical channel 3, and a negative pressure receiving mechanism 4. The horizontal channel 1, the transition channel 2, and the vertical channel 3 are connected in sequence. The horizontal channel 1 is provided with a first screen outlet 6 that is smaller than the diameter of the qualified tablet 5, and the vertical channel 3 is provided with a second screen outlet 7 that is smaller than the thickness of the qualified tablet 5. The air inlet of the negative pressure receiving mechanism 4 is connected to the first screen outlet 6 and the second screen outlet 7 respectively.

[0028] The tablets, arranged in a line, pass through the horizontal channel 1, the transition channel 2, and the vertical channel 3 in sequence. The tablets gradually stand upright from a horizontal position. During this process, horizontal fragments (fragments with missing parts on the periphery) are sucked out by negative pressure from the first sieve outlet 6 as the tablets roll forward due to the reduction in diameter. After passing through the first sieve, the tablets enter the vertical channel 3 and stand upright. The upright fragments (fragments with missing parts on the sides, especially the top of the two curved surfaces) are sucked out by negative pressure from the second sieve outlet 7 as the tablets roll forward due to the reduction in thickness. Finally, the tablets with relatively complete thickness and peripheral defects are screened out to ensure the quality of the finished product. Example

[0029] Based on the above embodiments, this embodiment, for example Figure 3 As shown, the slide in the transverse channel 1 is inclined, and the qualified tablet 5 abuts against the bottom surface of the slide.

[0030] The transverse channel 1 is inclined in two directions to reach the tilted tablet and abut against the bottom of the slide inside the transverse channel 1. At the same time, because the transverse channel 1 is inclined, the tablet rolls down automatically by gravity.

[0031] The rolling tablets will change state and encounter fragments with missing parts around the periphery. Once the gap is located at the bottom or top of the slide, it is exactly opposite to the first screen outlet 6, ensuring that the fragments are successfully sucked out. Example

[0032] Based on the above embodiments, this embodiment, for example Figure 1 As shown, an elastic pressure strip 8 is provided on the transverse channel 1, and the elastic pressure strip 8 abuts against the qualified tablet 5.

[0033] The elastic strip 8 ensures that the bottom of the tablet firmly abuts against the inner bottom of the slide of the transverse channel 1. The whole tablet will roll stably in the slide, and the side of the tablet will abut against the top and bottom of the first screen outlet 6 and will not be sucked out. The top of the fragment will not abut against the top of the first screen outlet 6 and can be sucked out smoothly.

[0034] Preferably, such as Figure 4 As shown, the first screen outlet 6 consists of multiple strip-shaped holes 61 with progressively increasing heights.

[0035] The height of the 61 slits varies to screen out fragments with varying degrees of defects.

[0036] Preferably, the first screen outlet 6 is located at the bottom of the transverse channel 1.

[0037] Preferably, such as Figure 5 As shown, the second screen outlet 7 is located at the top of the vertical channel 3.

[0038] The fragments are sucked out from the top of the vertical channel 3 to prevent them from getting stuck inside the channel 3 due to being sucked out from the bottom.

[0039] Preferably, the negative pressure receiving mechanism 4 includes a collection box 9, an air pipe 10, and a negative pressure device 11. Multiple collection boxes 9 are respectively installed on the first screen outlet 6 and the second screen outlet 7. The air inlet of the negative pressure device 11 is connected to the air outlet of the collection box 9 through the air pipe 10.

[0040] The negative pressure device 11 generates negative pressure, and the air pipe 10 is used to provide negative pressure to the collection box 9, where the debris is sucked into the collection box 9 for temporary storage.

[0041] Preferably, a filter screen 12 is provided inside the collection box 9.

[0042] The filter screen 12 is used to block debris and residue, preventing them from being lost with the airflow and wasting them.

[0043] Although the present invention 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 invention should be included within the protection scope of the present invention.
