[0002] In medicine, adjuvants are defined as excipients and additives used in the production of drugs and the preparation of prescriptions, that is, the general term for all materials except the main active ingredients of the drugs. They are important components of pharmaceutical preparations. In industrial production, auxiliary chemicals added to improve the production process, increase product quality and output, or to give the product certain unique application properties are also called additives. However, as an important component of the product matrix, large-dose supplements that have a significant impact on the product form, structure, and performance are generally not classified as adjuvants. The current forms of adjuvants include solid powder, liquid, and adhesive.

[0003] At present, when powdered additives are packaged by vacuum packaging, the powdered additives are first introduced into the packaging bag, and then the packaging bag is placed at the vacuum port, the bottom end of the packaging bag opening is located at the top end of the heating rod, the bag opening of the packaging bag is clamped by a clamping plate, the vacuum port extracts the air in the packaging bag, and then the packaging bag is sealed by the heating rod. However, when the air inside the packaging bag is extracted, the packaging bag as a whole is deformed, and the packaging bag shakes when deformed, which causes the packaging bag to shift, which causes the packaging bag opening to separate from the clamping plate, allowing external air to be introduced into the packaging bag, affecting the vacuum effect. At the same time, the offset packaging bag is not convenient for subsequent heating and sealing. Therefore, a vacuum packaging machine for the production of processing additives is provided.

[0029] It can be further explained that by vertically moving the clamping plate 403, the mouth of the packaging bag can be clamped and fixed, and by setting up the same power source, the two clamping seats 409 are driven to move toward each other, and the clamping seats 409 move and clamp and fix the outer wall of the packaging bag. The bag mouth and the bag body of the packaging bag are both in a clamped and fixed state when air is pumped out, ensuring that the packaging bag will not shake or move when air is pumped out. Compared with the traditional method of only clamping the bag mouth, the overall stability of the packaging bag when air is pumped out is further improved.

[0030] See also Figure 1The limiting mechanism 4 also includes a driving motor 401 arranged at one end of the fixing seat 2. The output end of the driving motor 401 is connected to a threaded column 402 through a coupling. The threaded column 402 is connected to the clamping plate 403 through a thread.

The interior of the moving block 410 is sleeved with a limiting rod 4101, and the limiting rod 4101 is fixedly connected to the inner wall of the second fixed box 5. The limiting rod 4101 and the moving block 410 are used to support the clamping seat 409, thereby ensuring the stability of the horizontal movement of the clamping seat 409.

[0033] It can be further explained that the rotation of the threaded column 402 simultaneously drives the rotating rod 404 to rotate, the rotation of the rotating rod 404 drives the first bevel gear 405 to rotate, the rotation of the first bevel gear 405 drives the second bevel gear 406 to rotate, the rotation of the second bevel gear 406 drives the bidirectional threaded rod 407 to rotate, the rotation of the bidirectional threaded rod 407 drives the two sliding blocks 408 to move toward each other, the movement of the sliding block 408 drives the clamping seat 409 to move, the two clamping seats 409 move toward each other and clamp the outer wall of the packaging bag.

[0034] Working principle: When in use, first place the packaging bag to be evacuated between the two clamping seats 409, and place the packaging bag opening at the top of the heating rod 6, so that the air extraction port 7 is in the packaging bag opening, and then the staff controls the driving motor 401 to work, the output end of the driving motor 401 rotates to drive the threaded column 402 to rotate, the threaded column 402 rotates to drive the clamping plate 403 to move downward, and the clamping plate 403 moves and clamps the packaging bag opening;

[0035] Secondly, the rotation of the threaded column 402 drives the rotating rod 404 to rotate at the same time, the rotation of the rotating rod 404 drives the first bevel gear 405 to rotate, the rotation of the first bevel gear 405 drives the second bevel gear 406 to rotate, the rotation of the second bevel gear 406 drives the bidirectional threaded rod 407 to rotate, the rotation of the bidirectional threaded rod 407 drives the two sliding blocks 408 to move toward each other, the movement of the sliding block 408 drives the clamping seat 409 to move, the two clamping seats 409 move toward each other and clamp the outer wall of the packaging bag;

[0036] Then, the air in the packaging bag is extracted through the air extraction port 7. After the interior of the packaging bag is vacuumized, the heating rod 6 is controlled to work, and the heating rod 6 heats and seals the packaging bag. Then, the output end of the driving motor 401 rotates in the opposite direction and drives the clamping plate 403 and the clamping seat 409 to reset and move through mechanical transmission. After the reset is completed, the staff can take down the packaging bag after the air is extracted;

[0037] Finally, by vertically moving the clamping plate 403, the mouth of the packaging bag can be clamped and fixed, and by setting up the same power source, the two clamping seats 409 are driven to move toward each other, and the clamping seats 409 move and clamp and fix the outer wall of the packaging bag. The bag mouth and the bag body of the packaging bag are both in a clamped and fixed state when air is pumped out, ensuring that the packaging bag will not shake or move when air is pumped out. Compared with the traditional method of only clamping the bag mouth, the overall stability of the packaging bag when air is pumped out is further improved.
