Technical Field

[0001] This utility model relates to the field of pharmaceutical testing technology, specifically a weighing and testing device. Background Technology

[0002] Medicines are special substances used by people to prevent and treat diseases, and for rehabilitation and health care. They mainly have functions such as prevention, treatment, and diagnosis. They can effectively regulate human physiological functions and have specified indications or functions, usage and dosage. In the pharmaceutical industry, medicines are usually individually packaged, usually in bags or bottles. After packaging, medicines have certain requirements for dosage. During the production and processing of medicines, it is necessary to test the weight after packaging to prevent the medicine bags from being too heavy or too light and failing to meet the standards. Weighing and testing devices are required during the testing.

[0003] However, existing weighing and testing devices measure the drugs by moving them onto the weighing scale and separating qualified and unqualified drugs. During testing, unqualified drugs can fall into two categories: those with a weight greater than the standard value and those with a weight less than the standard value. Since the subsequent handling methods for drugs in these two cases are different, and existing weighing and testing devices can only push unqualified drugs to the same position, they cannot push unqualified drugs in different situations to different positions, making them inconvenient to use.

[0047] The present invention will be further described below with reference to the accompanying drawings:

[0048] This embodiment:

[0049] Please see Figure 1-6 In this embodiment: a weighing detection device includes: a housing 1, a weighing component, a pushing structure, and a direction adjustment structure.

[0050] In this embodiment, the weighing component is disposed inside the outer casing 1 and is fixedly connected to the outer casing 1. The weighing component is used to weigh and measure the medicine.

[0051] In this embodiment, the weight of the medicine can be detected by operating the weighing component, and the operation of the feeding structure and the direction adjustment structure can be controlled based on the detected data.

[0052] The pushing structure is located directly above the weighing component and is fixedly connected to the outer casing 1, and is used to push the medicine to move.

[0053] In this embodiment, by operating the pusher structure, the completed drug can be pushed out, and the direction of the push is controlled by the direction adjustment structure.

[0054] The direction adjustment structure is connected to the pusher structure and is used to change the direction of the pusher structure.

[0055] In this embodiment, by activating the direction adjustment structure, the direction adjustment structure can change the pushing direction of the pushing structure, so that the pushing structure can push the material in three directions, corresponding to the two situations of qualified and unqualified drugs after drug testing. In this way, unqualified drugs in different situations can be pushed to different positions for easy use.

[0056] like Figure 3 and Figure 5 As shown, the direction adjustment structure includes: a spur gear 11, a rack 12, a limit rod 13, and a first electric push rod 14.

[0057] The shaft of the spur gear 11 is fixedly connected to the pusher structure.

[0058] In this embodiment, the spur gear 11 can drive the pusher structure to rotate, thereby changing the pushing direction of the pusher structure; the spur gear 11 is rotatably connected to the outer shell 1 above and can rotate under the support of the outer shell 1.

[0059] The rack 12 is disposed on the edge of the spur gear 11 and meshes with the spur gear 11; a through groove is provided on the surface of the rack 12.

[0060] In this embodiment, the spur gear 11 can be rotated by moving the rack 12.

[0061] The limiting rod 13 is disposed in the through groove and is slidably connected to the rack 12 through the through groove.

[0062] In this embodiment, the rack 12 can slide along the outer surface of the limiting rod 13, thereby restricting the direction of movement of the rack 12.

[0063] The output end of the first electric push rod 14 is fixedly connected to the side of the rack 12 away from the spur gear 11.

[0064] In this embodiment, the first electric actuator 14 is currently in a semi-extended state, meaning that the output end of the first electric actuator 14 can extend or retract at this time. The first electric actuator 14 is connected to an external processor, which can control the start and stop of the first electric actuator 14. The processor is existing technology and will not be described in detail here. The model of the first electric actuator 14 is selected according to actual needs, as long as it meets the working conditions.

[0065] When it is necessary to change the pushing direction of the pushing structure, the first electric push rod 14 is adjusted so that the output end of the first electric push rod 14 drives the rack 12 to move; the rack 12 will slide along the outer surface of the limit rod 13 and cause the spur gear 11 to rotate. The spur gear 11 simultaneously drives the entire pushing structure to rotate, thereby changing the pushing direction of the pushing structure. Different types of unqualified medicines can be pushed to different positions for easy use.

[0066] like Figure 2 and Figure 5 As shown, the pushing structure includes: motor 10, gearbox 7, rotating part 8 and actuating part 9.

[0067] Specifically, the upper end face of the motor 10 is fixedly connected to the shaft of the spur gear 11.

[0068] In this embodiment, the motor 10 is connected to an external processor, which can control the start, stop and rotation direction of the motor 10; the model of the motor 10 is selected according to actual needs, as long as it meets the working conditions.

[0069] The input end of the gearbox 7 is fixedly connected to the output end of the motor 10; the center of the rotating part 8 is fixedly connected to the output end of the gearbox 7.

[0070] In this embodiment, the reduction gearbox 7 is used to reduce the speed of the output end of the motor 10, thereby reducing the rotation amplitude of the rotating component 8.

[0071] One end of the actuating element 9 is fixedly connected to the side of the rotating element 8 near the reduction gearbox 7 and is located at the edge.

[0072] In this embodiment, when the rotating component 8 rotates, it will drive the actuating component 9 to revolve around the axis of the rotating component 8.

[0073] When it is necessary to push the medicine, the motor 10 is started. The output end of the motor 10 drives the rotating part 8 to rotate through the reduction gearbox 7. The rotating part 8 simultaneously drives the actuating part 9 to revolve around the axis of the rotating part 8. When the actuating part 9 rotates to the bottom, it will contact the medicine that has been tested. As the actuating part 9 continues to rotate, it pushes the medicine to move and pushes the medicine onto the corresponding conveyor belt.

[0074] like Figure 5 As shown, the surface of the actuating element 9 is provided with an arc-shaped groove, which is used to increase the contact area between the actuating element 9 and the medicine.

[0075] In this embodiment, the size of the arc-shaped groove is the same as the size of the medicine bottle.

[0076] like Figure 1 As shown, the surface of the outer shell 1 is evenly provided with a set of inlets and three sets of outlets to provide space for the transportation of medicines.

[0077] When pushing the medicine, the friction between the bottom of the medicine and the weighing pan 6 will prevent the medicine from moving in a straight line, thus preventing the medicine from moving onto the corresponding conveyor belt.

[0078] To address the aforementioned issues, this embodiment proposes an implementation method in which the weighing and detection device further includes three sets of limiting structures; each set of limiting structures is located at the discharge port to restrict the movement direction of the medicine.

[0079] like Figure 4 As shown, each set of limiting structures includes: a support frame 15, two sets of guide plates 16, two sets of fixing plates 17, two sets of elastic elements 18, two sets of vertical plates 19, a wedge block 20, and a second electric push rod 21.

[0080] One end of each guide plate 16 is rotatably connected to one side of the support frame 15.

[0081] In this embodiment, the bottom end of the support frame 15 is fixedly connected to the corresponding conveyor belt; at the same time, the support frame 15 can support the rotation of the guide plate 16.

[0082] Two sets of fixing plates 17 are symmetrically arranged on both sides of the support frame 15 and are fixedly connected to the support frame 15; each set of elastic elements 18 is arranged between the guide plate 16 and the fixing plate 17.

[0083] In this embodiment, the elastic element 18 is currently in a compressed state; when the guide plate 16 rotates outward, it will cooperate with the fixing plate 17 to compress the elastic element 18 again.

[0084] One end of each set of vertical plates 19 is fixedly connected to the upper end face of the guide plate 16; the two sides of the wedge block 20 are tightly fitted to the adjacent side of the two sets of vertical plates 19.

[0085] In this embodiment, when the wedge 20 moves horizontally, it can push the two sets of vertical plates 19 to move outward simultaneously; and the two sets of vertical plates 19 will always be in contact with the surface of the wedge 20 under the action of the elastic force of the elastic member 18.

[0086] The output end of the second electric push rod 21 is fixedly connected to the wedge block 20.

[0087] In this embodiment, the model of the second electric push rod 21 is selected according to actual needs, as long as it meets the working conditions.

[0088] When it is necessary to restrict the movement of the medicine, the second electric push rod 21 is adjusted. When the output end of the second electric push rod 21 pushes the wedge block 20 to move horizontally towards the weighing pan 6, the wedge block 20 will apply an outward force to the two sets of vertical plates 19. The vertical plates 19 will drive the guide plate 16 to move outward and cooperate with the fixed plate 17 to compress the elastic element 18 again. By changing the distance between the two sets of guide plates 16, so that the distance is slightly larger than the outer diameter of the medicine bottle, the movement direction of the medicine bottle can be restricted.

[0089] like Figure 6 As shown, the weighing assembly includes: a weighing instrument 5 and a weighing pan 6.

[0090] The weighing device 5 is located at the center of the outer casing 1, and the lower end face of the weighing device 5 is fixedly connected to the outer casing 1; the weighing pan 6 is located above the weighing device 5 and is fixedly connected to the weighing device 5.

[0091] In this embodiment, the weighing device 5 is connected to an external processor and transmits signals to the processor. When the medicine moves onto the weighing pan 6, the weighing device 5 detects the weight of the medicine and transmits signals to the processor. The signals are divided into qualified signals, signals below the standard value, and signals above the standard value. The processor uses different signals to control the first electric push rod 14 and the motor 10 to change the pushing direction of the pushing structure.

[0092] The weighing and testing device also includes: a conveying assembly; the conveying assembly is connected to the housing 1 and is used to convey medicines.

[0093] like Figure 1 and Figure 2 As shown, the conveying assembly includes: a feed conveyor belt 2, a finished product conveyor belt 3, and two sets of defective product conveyor belts 4.

[0094] One end of the feeding conveyor belt 2 passes through a set of feeding ports and extends to the edge of the weighing pan 6.

[0095] In this embodiment, the feed conveyor belt 2 is used to transport medicines into the interior of the device.

[0096] One end of the finished product conveyor belt 3 passes through the other two sets of discharge ports and extends to the edge of the weighing pan 6, and the finished product conveyor belt 3 is set parallel to the feed conveyor belt 2.

[0097] In this embodiment, the finished product conveyor belt 3 is used to transport qualified medicines out of the device.

[0098] The two sets of defective conveyor belts 4 pass through the discharge port at one adjacent end and extend to the edge of the weighing pan 6.

[0099] In this embodiment, the two sets of defective conveyor belts 4 are used to transport two different types of substandard drugs.

[0100] Working principle:

[0101] When using this weighing and detection device, the medicine is placed on the feeding conveyor belt 2, which transports the medicine to the weighing pan 6. At this time, the weighing device 5 detects the weight of the medicine and transmits a signal to the external processor.

[0102] When the transmitted signal indicates that the weight of the medicine is equal to the standard value, the processor will start the motor 10. The output of the motor 10 drives the rotating part 8 to rotate through the reduction gearbox 7. The rotating part 8 simultaneously drives the actuating part 9 to revolve around the axis of the rotating part 8. When the actuating part 9 rotates to the bottom, it will contact the medicine that has been tested. As the actuating part 9 continues to rotate, it pushes the medicine to move and pushes the medicine onto the finished product conveyor belt 3, thus transporting the qualified medicine out of the device.

[0103] When the transmitted signal indicates that the weight of the medicine is greater than the standard value, the processor will first activate the first electric push rod 14, causing the output end of the first electric push rod 14 to retract and drive the rack 12 to move. The rack 12 will slide along the outer surface of the limit rod 13 and cause the spur gear 11 to rotate. The spur gear 11 will simultaneously drive the entire pushing structure to rotate, thereby aligning the pushing direction of the pushing structure with a set of defective product conveyor belts 4. At this time, the processor will activate the motor 10 to push the medicine onto this set of defective product conveyor belts 4, thus realizing the pushing of unqualified medicines of different conditions to different positions for easy use.

[0104] When the transmitted signal indicates that the weight of the medicine is less than the standard value, the processor will first activate the first electric push rod 14, causing the output end of the first electric push rod 14 to extend and drive the rack 12 to move. The rack 12 drives the pushing structure to rotate through the spur gear 11, aligning the pushing direction of the pushing structure with another set of defective product conveyor belts 4. Subsequently, the processor will activate the motor 10 to push the medicine onto this set of defective product conveyor belts 4 and carry the medicine out of the device.

[0105] Before pushing out, the second electric push rod 21 is adjusted. When the output end of the second electric push rod 21 pushes the wedge 20 to move horizontally towards the weighing pan 6, the wedge 20 will apply an outward force to the two sets of vertical plates 19. The vertical plates 19 will drive the guide plate 16 to move outward and cooperate with the fixed plate 17 to compress the elastic element 18 again. By changing the distance between the two sets of guide plates 16, making the distance slightly larger than the outer diameter of the medicine bottle, the movement direction of the medicine bottle can be restricted. Then, the medicine is pushed out, completing the use of this device.

[0106] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
