Embodiment 1

[0039] The preferred solution of the present invention is as follows: a weighing device for small products. According to the above structural description, this solution provides an optimal implementation solution. Such as image 3 As shown, the guide seat 22 is in the shape of a right triangle, and its hypotenuse is an arc-shaped conveying track 221 , and the arc-shaped conveying track 221 and the circumferential surface of the transfer hub 21 are fitted together. Such as Figure 4 As shown, the weighing platform 41 includes a U-shaped guardrail 411, a V-shaped positioning groove 412 and a base 413, the base 413 is placed on the load cell 42, and the U-shaped guardrail 411 is arranged above the base 413 The bottom of the hollow part of the U-shaped guardrail 411 is provided with the V-shaped positioning groove 412 , and the opening surface of the U-shaped guardrail 411 is aligned with the outlet end of the arc-shaped conveying track 221 .

Abstract

The invention relates to a small product weighing device. The device comprises a feeding mechanism, a conveying and transferring mechanism, a fragment removing mechanism and a weighing mechanism, wherein the feeding mechanism comprises a hopper, a stirring mechanism and a sequencing mechanism, the conveying and transferring mechanism comprises a transferring hub, a guiding seat and a servo motor,the fragment removing mechanism comprises a guiding fork, a triggering mechanism, an air blowing device and a collecting box a, and the weighing mechanism comprises a weighing platform and a weighingsensor; the discharging mechanism comprises a discharging sliding groove a, a discharging sliding groove b, a removing door, a collecting box b and a collecting box c; the device further comprises a control unit, the trigger mechanism and the weighing sensor transmit signals to the control unit, the control unit can send instructions to the air blowing device, the servo motor and the removing door, and products meeting the weight requirement and products not meeting the weight requirement are separated. The problem that disturbance airflow is generated around the weighing platform due to vacuum leakage and the problem that the production efficiency is affected due to the fact that the stabilization time is long when small products are weighed are solved.

Description

technical field [0001] The invention belongs to the technical field of weighing equipment, and in particular relates to a weighing device for small products. Background technique [0002] At present, the existing weighing devices in the pharmaceutical industry adopt two methods: one method uses vacuum adsorption to transport tablets or pills above the weighing platform, and then releases them to the weighing pan for weighing; the other One method uses the vacuum suction wheel in conjunction with the transfer hub to transport the tablets or pills to the weighing table for weighing. Both methods have certain shortcomings, as follows: [0003] The first method: when weighing a tablet or pill, the next adjacent tablet or pill to be weighed is following the vacuum adsorption wheel to rotate toward the weighing platform, because the tablet or pill cannot fully fit the adsorption port , there is always a partial vacuum leak, resulting in disturbed air flow around the weighing pan...
