[0002] In the field of traditional Chinese medicine, many Chinese medicines have special shapes and are difficult to dispense and weigh mechanically. Most of them are still dispensed by manual picking and weighing. Many Chinese medicines contain dust particles. Long-term manual operation will have an adverse effect on the health of pharmacists, and the efficiency of manual picking is relatively low.

[0003] In response to the above problems, our company has focused on developing a machine that can automatically dispense irregularly shaped Chinese medicines. At present, the quantitative dispensing device and weighing mechanism have been completed, and corresponding patents have been applied for. The patent numbers are: "CN201920468522.2" and "CN202022073001.2".

[0022] The medicine bag heat sealing device of the Chinese herbal medicine packaging machine described in this specific embodiment needs to be controlled by a single-chip microcomputer when in use. Since using a single-chip microcomputer to control a stepper motor and a cylinder is a mature technology, and this application does not involve the electronic control part, it will not be described in detail here.

[0023] The principle of the heat sealing device for medicine bags of the Chinese medicine slice packaging machine described in this specific embodiment is as follows: Figure 1, the medicine bag 88 is sent between the inner mounting seat plate 9 and the outer mounting seat plate 13, the stepper motor 2 rotates, and drives the first screw 4 to rotate through the synchronous belt 3, and the screw of the first screw 4 pushes the inner mounting seat plate 9 to move toward the medicine bag 88, and the inner mounting seat plate 9 pulls the sliding plate 11 through the connecting piece 17 to drive the heat sealing plate 12 to move toward the medicine bag 88; at the same time, driven by the synchronous belt 3, the second screw 6 pushes the guide rod connecting plate 7 away from the medicine bag 88. At this time, the guide rod connecting plate 7 pulls the outer mounting seat plate 13 and the clamping cylinder 14 to move synchronously towards the medicine bag 88 through the shaft of the second linear guide pair 8, and the medicine bag 88 remains in position. When the clamping cylinder connecting shaft 15 moves to under the plug plate 18, the plug plate cylinder 10 pushes the plug plate 18 to clamp the clamping cylinder connecting shaft 15, and the locking nut 16 is blocked on the outside of the plug plate 18. At this time, the clamping cylinder 14 is retracted, and the clamping cylinder connecting shaft 15 will pull the sliding plate 11 further toward the medicine bag 88 and compress the spring 17-2. At this time, the heat sealing plate 12 is brought to the medicine bag 88 by the sliding plate 11 for heat sealing. After the heat sealing is completed, the clamping cylinder 14 extends outward, and under the action of the self-resetting force of the spring 17-2, the sliding plate 11 is pushed to reset, and the heat sealing plate 12 is away from the medicine bag 88 to complete the heat sealing work.

[0024] Preferably, the stepper motor 2 is a 57 stepper motor.

[0025] Preferably, two groups of the first linear guide rail pairs 5 are provided, which are symmetrically distributed on both sides of the first lead screw 4 , which have better stability than a single guide rail pair.

[0026] Preferably, two groups of the second screws 6 are provided, which are symmetrically distributed on both sides of the first screw 4, which has a better stability effect than a single screw.

[0027] Preferably, the second linear guide rail pairs 8 are provided with two groups, which are symmetrically distributed on both sides of the first lead screw 4, which has a better stability effect than a single guide rail pair.

[0028] Preferably, it further comprises a tensioning wheel 19 , which is mounted on the mounting base plate 1 and is used for adjusting the tightness of the synchronous belt 3 .

[0029] The medicine bag heat-sealing device of the Chinese herbal medicine slice packaging machine described in the present invention adopts a stepping motor and a screw drive to drive the inner mounting seat plate 9 and the outer mounting seat plate 13 to move toward and separate from the middle synchronously, so as to keep the position of the medicine bag 88 unchanged and provide a bag opening basis for the bag opening device; the heat-sealing plate 12 can be compressed and heat-sealed by the compression cylinder 14 alone. After the bag opening device and the clamping device are installed on the inner mounting seat plate 9, the bag opening and medicine dispensing and heat sealing can be used in the same set of equipment, and there is no need to equip the heat sealing device with a separate clamping device, which saves both the machine manufacturing cost and the energy consumption and improves the production efficiency.
