Traditional Chinese medicine delivery mechanism

technical field

The invention relates to traditional Chinese medicine production equipment, in particular to a diversion and sorting type traditional Chinese medicine conveying mechanism for bottled traditional Chinese medicines that are over-deficient, heavy and defective.

Background technique

In the automatic production process of traditional Chinese medicine, some traditional Chinese medicines are made into granules through the bottling mechanism, filling the granules in the medicine bottle until the total weight of the bottled traditional Chinese medicine meets the requirements, and then conveyed to the next process through the conveyor line and screwed on the bottle cap. During the bottling process, because there are Chinese medicine granules in the falling state and cannot stop when the output of Chinese medicine granules is stopped, resulting in overweight or the ejection of Chinese medicine granules, etc., the phenomenon of lack of weight is caused, and the overweight or lack of weight bottled Chinese medicine is defective Chinese medicine needs to be picked out. When the existing conveying line conveys bottled traditional Chinese medicine, it is not possible to select the defective bottled traditional Chinese medicine that is overweight and lacking in weight, but manually performs secondary weighing to determine whether the bottled traditional Chinese medicine is qualified.

SUMMARY OF THE INVENTION

The invention provides a diversion and sorting type traditional Chinese medicine conveying mechanism for bottled traditional Chinese medicines with excess and shortage of defective products, which solves the problem that the existing traditional Chinese medicine conveying lines cannot sort out the traditional Chinese medicines that are overweight and lacking in weight.

The above technical problems are solved by the following technical solutions: a traditional Chinese medicine conveying mechanism of over-deficient and heavy-quality bottled traditional Chinese medicine, which is divided and sorted, including a feeding conveyor belt, and is characterized in that it also includes a conveyor belt along the conveying direction of the feeding conveyor belt. The on-line weighing mechanism and the unloading conveyor belt are arranged in sequence forward. The loading end of the belt is also provided with a defective product processing workbench, and one side of the unloading conveyor belt is provided with a recycling workbench. The recycling workbench is provided with two inferior product feeding channels extending perpendicular to the conveying direction of the feeding conveyor belt, and the other side of the feeding conveyor belt is provided with two secondary feeding channels extending and retracting toward the recycling workbench. The product is pushed away from the cylinder, and the piston rod of the defective product is provided with a pushing plate. The material channels are aligned; the center of gravity of the bottled traditional Chinese medicine on the unloading conveyor belt is projected on the pusher plate along the horizontal direction; A defective product return conveyor belt, one of the defective product return conveyor belt transports the bottled Chinese medicine output from one of the product unloading channels to the defective product processing workbench, and the other defective product return conveyor belt to the other. The bottled traditional Chinese medicine output from the product feeding channel is transported to the defective product processing workbench. When in use, the online weighing mechanism weighs the weight of the bottled Chinese medicine. If it is overweight, when the bottled Chinese medicine is transported to a defective product before being pushed out of the cylinder, it is pushed into a defective product unloading channel through the defective product pushed out of the cylinder, and finally passes through a The secondary sheet recirculation conveyor belt is transported to the defective product processing workbench; if there is a lack of weight, when the bottled Chinese medicine is transported to another defective product before being pushed out of the cylinder, it is pushed out of the cylinder by the defective product and pushed into another defective product unloading channel. It is transported to the defective processing workbench by another secondary sheet return conveyor belt. "The projection of the center of gravity of the bottled Chinese medicine on the unloading conveyor belt toward the pusher plate in the horizontal direction is located on the pusher plate", so that it is not easy to produce the bottle dumping phenomenon when the bottled Chinese medicine is pushed out, so as to avoid the secondary push-out phenomenon. When the Chinese medicine is bottled, the Chinese medicine particles are poured out and polluted, which leads to scrapping. The technical solution enables the personnel who process the product on the defective product processing workbench to conveniently and intuitively know whether the reflowed defective bottled Chinese medicine is overweight or lacking weight. Then take out the traditional Chinese medicine granules to the lack of weight and then return them to the bottling mechanism to supplement the traditional Chinese medicine granules.

Preferably, the front end of the push plate along the conveying direction of the unloading conveyor belt is provided with an anti-dump baffle that is bent toward the direction of the recovery platform. It can prevent the bottled Chinese medicine from being poured forward during the process of bottled Chinese medicine.

At the same time, the cylinder body of the defective product is pushed away from the cylinder, the inflatable sleeve and the ejector plate enclose an air cavity, and a piston is arranged in the cylinder of the defective product to be pushed away from the cylinder, and the piston pushes the defective product away from the cylinder. The cylinder is divided into a rod cavity and a rodless cavity, and the piston rod of the defective product pushed away from the cylinder is connected to the piston and protrudes through the rod cavity to be connected with the push plate, so The rod cavity is provided with a rod cavity air hole, the rodless cavity is provided with a rod cavity air hole, the rodless cavity air hole is provided with a one-way valve that opens toward the interior of the rod cavity, and the air cavity and The rodless cavities are communicated through a control valve, the inflatable sleeve is also provided with an exhaust mechanism that discharges the gas in the inflatable sleeve when the push-pull cylinder shrinks, and the control valve extends out when the defective product is pushed away from the cylinder Open, the control valve is closed when the defective product is pushed away from the cylinder for contraction. By means of structure detection, the phenomenon of pinching hands or objects between the ejector plate and the cylinder block is prevented when the defective product is pushed away from the cylinder and shrinks, and the safety during operation is improved. Moreover, when the defective product is pushed out of the cylinder to make the ejector plate away from the cylinder block, the volume of the air cavity increases to form a negative pressure cavity, which can accelerate the outflow of the gas in the rod cavity, which can make the defective product Faster response when pushed away from the cylinder to extend. The gas in the rod cavity flows into the air chamber, so that the inflatable sleeve is less likely to be indented so as to improve the strength of the inflatable sleeve. Therefore, it is avoided that the protective effect of the inflatable sleeve is excessively reduced after being stretched.

Preferably, the exhaust mechanism includes a plurality of exhaust passages, the inlets of the exhaust passages are arranged on the part of the ejector plate located in the air cavity, and the outlets of the exhaust passages are located in the ejector plate On the part outside the air cavity, when the output of the piston rod pushes the ejector plate, the piston rod seals the inlet of the exhaust passage, and when the piston rod shrinks to pull the ejector plate, the The piston rod is disconnected from the inlet of the exhaust passage. The synchronizing opening and closing of the exhaust mechanism can be automatically realized by the expansion and contraction of the piston rod.

Preferably, the ejector plate is provided with a suction hole penetrating the ejector plate along the conveying direction perpendicular to the feeding conveyor belt, and the outlet end of the exhaust passage is provided with a suction hole pierced through the suction hole. The air outlet nozzle, the outlet method of the outlet nozzle is directed to the end of the suction hole away from the recovery workbench. In the process of rejecting defective bottled Chinese medicine, when the pusher plate reaches the end of the stroke for recycling, the pusher plate loses its support for the bottled Chinese medicine, and the bottled Chinese medicine continues to move forward under the action of inertia, and the bottom of the medicine bottle is recycled due to the same The friction between the workbench or the feeding conveyor belt will cause a slowdown, which may cause the bottled Chinese medicine to have a tendency to lean forward, which may cause the bottled Chinese medicine to tip over. In this technical solution, when the defective product is pushed away from the cylinder to shrink, the gas in the air cavity will be discharged to make the suction hole produce a suction effect. Generates an adsorption force, which can exert a backward force on the bottle body of the bottled Chinese medicine, thereby reducing the possibility of the above dumping phenomenon, making it more difficult for the inferior bottled Chinese medicine to be pushed away.

The invention has the following advantages: the defective bottled traditional Chinese medicine can be selected for recycling, and the overweight and underweight defective bottled traditional Chinese medicines are separated and separated for pushing and recycling, which improves the convenience of follow-up work; the introduction of defective bottled traditional Chinese medicine It is not easy to fall over when the defective product is pushed away from the cylinder and retracted, and the safety is good.
