DETAILED DESCRIPTION

[0020] In order to more clearly illustrate the technical solution of the utility model, the utility model is further described below in conjunction with the accompanying drawings. Obviously, the accompanying drawings described below are only one embodiment of the utility model. For ordinary technicians in this field, without paying any creative work, other embodiments can be obtained based on this drawing and embodiment, which all belong to the protection scope of the utility model.

[0021] according to Figure 1-6 As shown, an online sampling and weighing instrument for tablets and capsules comprises a workbench 1, a feeding assembly is arranged above the workbench 1, a weight detection assembly is arranged at the end of the feeding assembly, the weight detection assembly performs weight detection on the capsules passing through, and the detected capsules are discharged through the first channel 2 or the second channel 3.

[0022] In the above specific technical scheme, the capsule falls onto the weight detection component through the feeding component, and static weighing is realized on the weight detection component with high detection accuracy. After the detection, the qualified capsules are discharged through the first channel 2, and the unqualified capsules are discharged through the second channel 3, thereby realizing the separation of qualified capsules and unqualified capsules, and facilitating the collection of qualified capsules and unqualified capsules.

[0023] The feeding assembly includes a vibrating plate 4 installed on the workbench 1, an inclined feeding pipe 5 is provided above the vibrating plate 4, the feeding pipe 5 is connected with the sorting pipe 6, a material guide channel 7 is provided at the discharge port of the vibrating plate 4, and the material guide channel 7 is located above the weight detection assembly. By setting the vibrating plate 4, it is beneficial for the capsules to fall onto the weight detection assembly in an orderly manner for weight detection.

[0024] The sorting tube 6 is located above the feeding tube 5 and is in an inclined state. A feeding port 8 is provided at the connection between the sorting tube 6 and the feeding tube 5. A flip plate 9 is provided at the feeding port 8. The flip plate 9 is connected to a driving electromagnet 10. The driving electromagnet 10 is fixedly mounted on the sorting tube 6. A capsule detection device is provided upstream of the sorting tube 6, such as a metal detector for detecting whether the capsule contains metal impurities. The capsule enters the sorting tube 6 after passing the detection of the detection device. The capsule that does not meet the standards slides along the inclined sorting tube 6 under the action of gravity. When the capsule that meets the standards passes through, the flip plate 9 rotates under the action of the driving electromagnet 10, the feeding port 8 opens, and the capsule that meets the standards falls into the feeding tube 5 and falls onto the vibration plate 4 through the feeding tube 5.

[0025] The weight detection assembly includes a checkweigher 11, a weighing slot 13 for accommodating capsules is provided on a weighing platform 12 of the checkweigher 11, guide plates 14 are provided on both sides of the weighing platform 12, and a first channel 2 for passing qualified capsules and a second channel 3 for passing unqualified capsules are provided below the guide plates 14 on both sides, so that the capsules can fall in an orderly manner through a vibrating plate 4 and fall into the weighing slot 13 for static weighing. The guide plates 14 on both sides of the weighing platform 12 are conducive to the unloading of qualified capsules and unqualified capsules through the first channel 2 and the second channel 3 respectively.

[0026] The upper cover of the weight detection component is provided with a dust cover 15, and blowing devices 16 are installed on both sides of the dust cover 15. The pipeline connected to the blowing device 16 extends into the dust cover 15 through a fixing seat 17. The pipelines corresponding to the two blowing devices 16 stand opposite to each other and are located above the checkweigher 11. By arranging the blowing device 16, qualified products and unqualified products are blown out respectively. Preferably, the air outlets of the blowing pipelines are respectively located obliquely above the weighing platform 12, so as to blow the capsule out of the weighing slot 13. When the checkweigher 11 detects that the weight of the capsule is qualified, the blowing device 16 corresponding to the qualified capsule is started to blow the qualified capsule into the first channel 2. When the checkweigher 11 detects that the weight of the capsule is unqualified, the blowing device 16 corresponding to the unqualified capsule is started to blow the unqualified capsule into the second channel 3.

[0027] A protective cover 18 is provided on the top of the checkweigher 11 to prevent dust from falling into the capsule in the working environment. At the same time, opening the protective cover 18 facilitates cleaning of the weighing platform 12.

[0028] The vibrating plate 4 is covered with a shell 19 , and the top of the shell 19 is provided with an end cover 20 . The shell 19 has a dustproof effect, and opening the end cover 20 facilitates cleaning of the vibrating plate 4 .

[0029] Both sides of the checkweigher 11 are inclined surfaces 21 for unloading materials, so that the air blowing device 16 can blow the capsules in the weighing slot 13 onto the guide plate 14 .
