Description

Technical Field

[0001] The utility model relates to the field of drug detection equipment, in particular to a drug detection and waste rejection device. Background Technique

[0002] The quality of drugs is related to people's life and health, and also to the reputation of enterprises. The government and enterprises attach great importance to drug quality detection. Almost every link in the pharmaceutical production process requires drug detection to ensure drug quality. With the continuous progress of technology, the regulatory requirements for drug quality will also continue to increase. In the future, enterprises that do not meet the requirements will be gradually eliminated. With the continuous improvement of the product quality requirements of pharmaceutical factories, drug detection equipment has developed rapidly at home and abroad. At the same time, the problem faced is whether the unqualified products in the detection can be effectively removed to reduce the waste risk.

[0003] At present, most domestic detection equipment uses the method of positive pressure blowing and mechanical flap waste rejection to treat the unqualified materials detected. Positive pressure blowing easily causes the unqualified materials to fly. Due to the uncertainty of the positive pressure blowing air flow, the blown unqualified products cannot enter the waste collection device well, resulting in incomplete collection of waste products, and there is a possibility of mixing into the finished product collection box or being blown outside the equipment. At the same time, the risk of mis-rejection in positive pressure waste rejection is relatively large. The mechanical flap structure is prone to fatigue and jamming. After the mechanical flap generates fatigue, when there is waste to be rejected, the flap cannot be lifted smoothly, or the lifting is not smooth, resulting in the drug not being rejected or the waste rejection action being discontinuous, which causes the waste product to enter the finished product collection box and affects the accuracy of the entire production. Summary of the Utility Model

[0032] It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments may be combined with each other.

[0033] The present utility model will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0034] As Figures 1-8 shown, the present utility model is a drug detection and rejection device, which includes a bracket 1, a vacuum blowing block 2, a vacuum suction pipe 3, a vacuum exhaust pipe 4, and a rejection receiving box 5. The vacuum blowing block 2 and the rejection receiving box 5 are respectively installed on the bracket 1. The vacuum blowing block 2 is provided with a plurality of channels, and each channel is correspondingly provided with a first air inlet 21, a first air outlet 22, and a positive pressure hole 23. The first air inlet 21 and the first air outlet 22 are communicated, and the positive pressure hole 23 is arranged above the first air outlet 22. A connector 8 is installed at each position of the positive pressure hole 23 for connecting a positive pressure air source. At the same time, a solenoid valve (not shown in the figure) is provided on each connector 8, and each solenoid valve is electrically connected to the control unit. The control unit can control a single solenoid valve or simultaneously control the opening or closing of multiple solenoid valves. The solenoid valve is used to control the opening or closing of the positive pressure air source. Each first air inlet 21 is respectively connected to a vacuum suction pipe 3, and each first air outlet 22 is respectively connected to a vacuum exhaust pipe 4. The end of the vacuum exhaust pipe 4 far away from the vacuum blowing block 2 extends into the rejection receiving box 5. The positive pressure air source and the control unit are both prior arts. The control unit can be installed on the bracket 1 or can be separately arranged outside the drug detection and rejection device.

[0035] One vacuum suction pipe 3 corresponds to one duct, one duct corresponds to one positive pressure hole 23, one positive pressure hole 23 corresponds to one connector 8, and one connector 8 corresponds to one solenoid valve. Therefore, it is equivalent that one vacuum suction pipe 3 corresponds to one solenoid valve. When unqualified drugs are conveyed below the vacuum suction pipe 3, the solenoid valve corresponding to the vacuum suction pipe 3 is opened. Then, under the action of vacuum negative pressure, the unqualified drugs will be attracted to the waste rejection receiving box 5 in sequence through the corresponding vacuum suction pipe 3, vacuum blowing block 2, and vacuum exhaust pipe 4. Multiple vacuum suction pipes 3 can reject single or multiple unqualified drugs simultaneously. Specifically, when only one solenoid valve is opened, the rejection of a single unqualified drug can be achieved. When multiple solenoid valves are opened simultaneously, the simultaneous rejection of multiple unqualified drugs can be achieved. The present utility model adopts the method of waste rejection by vacuum negative pressure, and the waste rejection action is safe and reliable without the hidden danger of missed rejection. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "vertical", "horizontal", "upper", "lower", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise specified, the meaning of "multiple" is two or more.

[0036] The vacuum blowing block 2 further includes a positive pressure connection hole 24 and an adjustment hole 25. The positive pressure connection hole 24 is of an annular groove structure. At the same time, the positive pressure connection hole 24 communicates with the positive pressure hole 23. The adjustment hole 25 is arranged on both sides of the vacuum blowing block 2. At the same time, the adjustment hole 25 is threadedly connected with the adjustment bolt 7 arranged on the bracket 1. By tightening or loosening the adjustment bolt 7, the height adjustment of the vacuum blowing block 2 in the vertical direction can be achieved. In the actual application process, the height of the vacuum blowing block 2 can be adjusted with the adjustment bolt 7 according to the actual height of the detected drugs to ensure that unqualified products can be effectively rejected.

[0037] A finished product discharge chute 6 is further installed on the bracket 1, and the finished product discharge chute 6 is arranged below the waste rejection receiving box 5.

[0038] A cover plate 9 is detachably installed on the waste rejection receiving box 5. The presence of the cover plate 9 can effectively prevent the splashing of unqualified drugs. Preferably, the cover plate 9 is made of a transparent material, which is convenient for the staff to directly see the situation inside the waste rejection receiving box 5.

[0039] A first air outlet 10 is provided on the waste rejection and material receiving box 5; a second air outlet 11 is provided on the cover plate 9. The existence of the first air outlet 10 and the second air outlet 11 effectively ensures that unqualified drugs can be smoothly attracted into the waste rejection and material receiving box 5.

[0040] The vacuum suction pipe 3 includes a pipe structure 31 and a first connecting plate 32. One end of the pipe structure 31 is connected to the first connecting plate 32. The lumen of the pipe structure 31 is communicated with the through holes provided on the first connecting plate 32. At the same time, the first connecting plate 32 is detachably connected to the vacuum blowing block 2. During the actual working process, the vacuum suction pipe 3 can be made in various sizes of different specifications, and a vacuum suction pipe 3 of a suitable specification is selected for use according to the size of the actual drug.

[0041] A second air inlet hole 43 and a second air outlet hole 44 are coaxially provided on the vacuum exhaust pipe 4, and the second air inlet hole 43 and the second air outlet hole 44 are communicated. A plurality of positive pressure channels 42 are provided on the second connecting plate 41 of the vacuum exhaust pipe 4. The plurality of positive pressure channels 42 are circularly arrayed along the central axis of the second air inlet hole 43. At the same time, each positive pressure channel 42 is communicated with the second air outlet hole 44. When the vacuum exhaust pipe 4 is connected to the vacuum blowing block 2, the central axis of the array of the plurality of positive pressure channels 42 of the vacuum exhaust pipe 4 coincides exactly with the central axis of the positive pressure connection hole 24. At the same time, the groove width of the positive pressure connection hole 24 is greater than the hole diameter of the positive pressure channel 42. Therefore, it can effectively ensure that all the positive pressure channels 42 are covered and surrounded by the positive pressure connection hole 24. The second air outlet hole 44 is of a two-stage structure, wherein the first-stage hole structure is connected to the second air inlet hole 43 and is a frustum-shaped hole structure, and the second-stage hole structure is far from the second air inlet hole 43 and is an equal-diameter hole structure. At the same time, the diameter of the end of the first-stage hole structure connected to the second air inlet hole 43 is greater than the diameter of the second air inlet hole 43. The vacuum exhaust pipe 4 generates a vacuum through the flow of compressed air to suck unqualified drugs into the waste rejection and material receiving box 5. During the actual working process, the vacuum exhaust pipe 4 can be made in various sizes of different specifications, and a vacuum exhaust pipe 4 of a suitable specification is selected for use according to the size of the actual drug.

[0042] The control unit electrically connected to the solenoid valves can not only receive the command signals sent by the upstream detection device, but also control the opening or closing of each solenoid valve. During the actual working process, both the upstream detection device and the drug detection and rejection device of the present utility model are workstations with determined positions. When the detection device detects unqualified drugs, it will send the positioning signal of the position where the unqualified drugs are located to the control unit. After receiving the positioning signal, the control unit will send a rejection instruction to the solenoid valve corresponding to the position of the unqualified drugs. When the unqualified drugs reach the area below the vacuum suction pipe 3, that is, the rejection position, the solenoid valve corresponding to the position of the unqualified drugs will open, and the positive pressure air source will be introduced into the vacuum blowing block 2 for vacuum rejection. The unqualified drugs will sequentially pass through the vacuum suction pipe 3, the channels of the vacuum blowing block 2, and the vacuum exhaust pipe 4, and then be attracted into the rejection receiving box 5. The duration of this action can be controlled. After a rejection cycle ends, the solenoid valve closes and waits for the next rejection instruction. The upstream detection device is prior art.

[0043] During the actual working process, the drug detection and rejection device of the present utility model is arranged downstream of the drug detection device. At the same time, the drug detection and rejection device is installed at the end of the drug roller conveying device. The roller conveying device is driven by a motor to drive a sprocket for closed-loop operation. When the upstream detection device completes the drug detection, it will convey the drugs to the area below the vacuum suction pipe 3 of the drug detection and rejection device through the roller conveying device.

[0044] When the upstream detection device detects unqualified drugs, it will send the positioning signal of the position where the unqualified drugs are located to the control unit. After receiving the positioning signal, the control unit will send a rejection instruction to the solenoid valve corresponding to the position of the unqualified drugs. When the unqualified drugs reach the area below the vacuum suction pipe 3, the solenoid valve corresponding to the position of the unqualified drugs will open. At this time, the positive pressure air source is connected for vacuum rejection. Since one solenoid valve corresponds to one vacuum suction pipe 3, when the solenoid valve opens, the unqualified drugs will sequentially pass through the vacuum suction pipe 3, the channels of the vacuum blowing block 2, and the vacuum exhaust pipe 4, and then be attracted into the rejection receiving box 5. The qualified products will fall from the roller conveying device into the finished product discharge chute 6. The roller conveying device is prior art.

[0045] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
