Description

Intelligent dispensing system for traditional Chinese medicine decoction pieces

Technical Field

The invention relates to the technical field of traditional Chinese medicine production, in particular to an intelligent dispensing system for traditional Chinese medicine decoction pieces.

Background

During the production process of traditional Chinese medicine, the traditional Chinese medicine is prepared by traditional Chinese medicine decoction pieces through a preparation mechanism (the traditional Chinese medicine decoction pieces with set weight are weighed to be called as the preparation). The existing dispensing equipment can only dispense one traditional Chinese medicine, and when one prescription is dispensed, the traditional Chinese medicines dispensed by different dispensing mechanisms need to be manually transferred into a decoction barrel, so that the automation degree of the traditional Chinese medicine dispensing is low. In addition, the dispensing mode of the existing Chinese herbal piece dispensing equipment is still a one-time weighing mode which has been adopted for a long time. Because the Chinese herbal pieces have the characteristics of different shapes and sizes, cross connection, complex adhesion and the like, the overweight problem is easy to generate during dispensing. If the weight of the traditional Chinese medicine decoction pieces is overweight during dispensing by the machine, the traditional Chinese medicine decoction pieces in the weighing scale are required to be poured out and reweighed, so that the quantity of the traditional Chinese medicine decoction pieces which need to be weighed repeatedly during dispensing is large, the traditional Chinese medicine decoction pieces are conveyed and discharged by the discharging mechanism during dispensing by the machine, a certain quantity of the traditional Chinese medicine decoction pieces are damaged each time the material is fed, the larger the repeated weighing quantity is, the larger the quantity of the damaged traditional Chinese medicine decoction pieces is, and the medicine effect is damaged due to the over-crushing of the traditional Chinese medicine decoction pieces.

Referring to fig. 5, 6, 7 and 8, the blanking mechanism 2 includes a feed hopper 25, a discharge port 26 and a screw feeder 27 for feeding the herbal pieces from the feed hopper to the discharge port. The discharge port is provided with a discharging brush 28 for brushing off the herbal pieces in the output end of the screw feeder and a brush rotating motor 29 for driving the discharging brush to rotate. The brush rotating motor 29 is a motor. The blanking brush 28 comprises a rotary disk 281 and 4 rows of blanking bristles 282 arranged on the rotary disk and distributed along the circumferential direction of the rotary disk. A turntable drive shaft 2811 is provided on one side of the turntable, and a drive rod 2812 is provided on the other side. The brush rotation motor 29 drives the turntable to rotate by being connected to the turntable drive shaft. The turntable drive shaft and the drive rod are coaxial and extend in the axial direction of the turntable. The bristles in the same row of bristles are distributed along the radial direction of the rotating disc. The bristles extend in the axial direction of the rotating disc. A discharge space S2 is formed between the turntable and the discharge end of the spiral feeder. The discharge port is positioned at the lower side of the discharge space, and a discharge channel is formed between the adjacent rows of bristles. The driving rod is positioned in the discharging space. One end of the driving rod far away from the turntable is provided with 3 material poking rods 283 which radially extend along the circumferential direction of the driving rod. The free ends 2821 of the bristles extend beyond the kick-off bar in the direction of extension of the kick-off bar. The driving rod, the turntable and the spiral feeder are coaxial.

Referring to fig. 5 and 6, the upper scale and the lower scale have the same structure. The upper weighing scale 3 comprises an upper weighing scale body 31 and an upper weighing scale part weighing hopper 32 for receiving the traditional Chinese medicine decoction pieces output by the blanking mechanism. The upper weighing part weighing hopper comprises an upper weighing part funnel 321, an upper weighing part funnel cover plate 322 for sealing the discharge end of the upper weighing part funnel, and an upper weighing part funnel cover plate opening and closing mechanism 323 for driving the upper weighing part funnel cover plate to open and close.

Referring to fig. 4, fig. 5, fig. 6, fig. 7 and fig. 8, the method for weighing the herbal pieces of the desired weight in the formula by the herbal piece dispensing mechanism in the 2 nd step is that, in the 2 nd step, coarse weighing is performed, specifically, the herbal pieces are output to a lower weighing hopper by a blanking mechanism, and the blanking is stopped by the blanking mechanism when the weight of the herbal pieces in the lower weighing hopper reaches N, where N is less than the dosage M required by the herbal pieces; step 2.2, fine weighing, namely outputting the traditional Chinese medicine decoction pieces to an upper weighing scale hopper for weighing through a blanking mechanism, and stopping blanking through the blanking mechanism when the weight of the traditional Chinese medicine decoction pieces falling into the upper weighing scale hopper is more than M-N; step 2.3, removing the abnormal weight, namely when the weight of the traditional Chinese medicine decoction pieces falling into the upper weighing scale hopper is larger than M-N, driving the receiving hopper to move to the position below the upper weighing scale hopper by the receiving hopper moving mechanism, then opening a cover plate of the upper weighing scale hopper, so that the traditional Chinese medicine decoction pieces in the upper weighing scale hopper fall into the receiving hopper, and repeating the step 2.2; 2.4, when the weight of the traditional Chinese medicine decoction pieces falling onto the upper weighing scale in the step 2.2 is equal to M-N g, the traditional Chinese medicine decoction pieces in the upper weighing scale hopper and the lower weighing scale hopper fall into the lower hopper; the feeding method of the feeding mechanism is that the traditional Chinese medicine is conveyed from the feed hopper to the feeding opening through the spiral feeder, and the traditional Chinese medicine reaching the outlet end of the spiral feeder falls out from the feeding opening through the brushing of the rotary feeding brush. N in the step 2.1 is more than 75% of M.

The specific blanking mode in this embodiment is: the herbal pieces are fed into the hopper 25 and moved toward the discharge space by the screw feeder 27, and the brush is rotated by the brush driving mechanism. When the decoction pieces extend out of the outlet section of the contact feeder to be contacted with the bristles of the brush, the decoction pieces are brushed down by the bristles and are transferred into the blanking channel to finally fall out of the discharge port, then the Chinese medicine decoction pieces are extruded tightly without being brushed down by the bristles, and then the Chinese medicine decoction pieces are contacted with the material stirring rod, so that the Chinese medicine decoction pieces are stirred down by the rigid material stirring rod. In order to obtain good feeding effect by the brush at a higher speed, the rotating direction of the brush is opposite to that of the spiral feeder.

In this embodiment, the herbal pieces are manually transferred to the blanking mechanism. Certainly, the receiving hopper can be designed into a structure like the upper weighing part weighing hopper shown in fig. 3, at the time of rough weighing, if the receiving hopper is internally provided with the traditional Chinese medicine decoction pieces, the receiving hopper extends out and is positioned on the lower weighing part weighing hopper, then the receiving hopper is opened to enable the traditional Chinese medicine decoction pieces in the receiving hopper to be transferred to the lower weighing part weighing hopper to enable the weight of the traditional Chinese medicine decoction pieces to meet the requirement, when the weight of the traditional Chinese medicine decoction pieces weighed out by the lower weighing part weighing hopper is not enough, the receiving hopper is contracted to avoid, and then the traditional Chinese medicine decoction pieces in the blanking mechanism are transferred to the lower weighing part weighing hopper to enable the weight of the traditional Chinese medicine decoction pieces roughly weighed to meet the requirement.
