Description

Technical Field

[0001] The utility model relates to the technical field of powder packaging, and specifically, to a packaging device for purified zinc oxide powder. Background Art

[0002] Zinc oxide is a common inorganic compound, insoluble in water and ethanol, but soluble in solutions such as acids and alkalis. As a commonly used chemical additive, zinc oxide is widely used in the production of products such as plastics, silicate products, synthetic rubber, lubricating oil, paint coatings, ointments, adhesives, food, batteries, flame retardants, etc. For purified zinc oxide, due to its high purity and better chemical stability, the packaging should prevent zinc oxide from reacting with moisture, oxygen, etc. in the air, resulting in performance degradation.

[0003] In the prior art, after the production of zinc oxide is completed, a packaging bag is sleeved on the discharge port of the leakage hopper, and a clamping mechanism clamps the packaging bag. Then, the discharge port starts to discharge materials. When a certain amount of zinc oxide is filled in the packaging bag, the clamping mechanism relaxes the packaging bag, and the packaging bag falls onto the conveyor belt structure below the discharge port. Then, the conveyor belt structure moves the unsealed packaging bag filled with zinc oxide to the sealing mechanism for sealing. Then, through the bag-inverting mechanism, the sealed packaging bag is rotated by 90°, and then the packaging bag is laid down. After being shaped by the shaping mechanism, it is palletized by the palletizing mechanism. For example, the utility model patent with the patent publication number CN216994913U discloses a packaging machine for preventing zinc oxide from flying. This device fixes the packaging bag below the storage tank and fills zinc oxide powder into the packaging belt through the discharge pipe below the storage tank. After filling a certain amount of zinc oxide powder in the packaging bag, the conveyor belt structure moves the open packaging bag filled with zinc oxide to the sealing mechanism for sealing.

[0004] However, when the open packaging bag filled with zinc oxide is moved to the sealing mechanism by the conveyor belt structure for sealing, the zinc oxide in the open packaging bag will come into contact with the air during the movement, which will to a certain extent affect the quality of zinc oxide and lead to performance degradation.

[0065] Specifically, the second driving assembly includes: a rotating block 28, an annular gear 29, a driving gear 30 and a third motor 31. A plurality of rotating blocks 28 are fixedly connected to the bottom of the guide disk 23. The plurality of rotating blocks 28 are slidably connected to the guide rail plate 22.

The third motor 31 is installed on the machine frame 1, and the output end of the third motor 31 is fixedly connected to the driving gear 30.

[0066] The purified zinc oxide powder packaging device further includes a rotating mechanism, which includes: a first gear 32, a rotating table 33, a second gear 34 and a fourth motor 35. The first gear 32 is rotatably connected to the workbench 13. The rotating table 33 is fixedly connected to the top of the first gear 32. The second gear 34 is rotatably connected to the workbench 13. The second gear 34 meshes with the first gear 32. The fourth motor 35 is installed on the workbench 13, and the output end of the fourth motor 35 is fixedly connected to the second gear 34.

[0067] The working principle of the purified zinc oxide powder packaging device is as follows: After the operator sleevs the packaging bag on the discharge port, the third motor 31 rotates, driving the driving gear 30 to rotate, and then driving the annular gear 29 to rotate, and then driving the guide disk 23 to rotate relative to the guide rail plate 22. At the same time, the clamping shaft 25 slides in the guide groove, and then drives the clamping slider 24 to slide in the guide rail groove. The clamping frame 26 moves towards the direction close to the discharge port, clamping the packaging bag at the discharge port, and then the discharge port starts to discharge materials.

[0068] After a certain amount of purified zinc oxide is contained in the packaging bag, the discharge port is closed, and the second motor 11 rotates, driving the first lead screw 10 to rotate, and then driving the first slider 12 to slide on the first guide rail 9 to move the clamping block 6 to the position of the packaging bag. Then the second motor 11 stops rotating, and then the first motor 8 rotates, driving the clamping lead screw 5 to rotate, so that the two clamping blocks 6 move relatively closer.

[0069] After the two clamping blocks 6 clamp the packaging bag, the third motor 31 rotates in reverse to release the packaging bag by the clamping frame 26. Then the fifth motor 19 rotates, driving the second lead screw 17 to rotate, and then driving the frame 21 to slide between the guide rod 16, the limit block 20 and the bracket 18, so that the packaging bag descends.

[0070] After the packaging bag descends onto the rotating table 33, the second motor 11 rotates again, driving the clamping block 6 and the workbench 13 to move synchronously to the sealing mechanism 2 for sealing.

[0071] After the packaging bag is sealed, the first motor 8 rotates in reverse, driving the first lead screw 10 to rotate in reverse, so that the two clamping blocks 6 move relatively away from each other. After the two clamping blocks 6 release the packaging bag, then the fourth motor 35 rotates, driving the second gear 34 to rotate, and then driving the first gear 32 to rotate, and then the rotating table 33 rotates, so that the packaging bag rotates 90° on the rotating table 33. At the same time, the second motor 11 keeps rotating, driving the workbench 13 to move.

[0072] When the buffer pad 15 fixedly connected to the workbench 13 contacts the conveyor belt structure 3, the workbench 13 is blocked by the conveyor belt structure 3 and is stationary relative to the conveyor belt structure 3. While the first slider 12 maintains the original direction, the workbench 13 slides relative to the first slider 12, and at the same time the spring is stretched. Then the pushing frame 14 fixedly connected to the first slider 12 pushes the packaging bag to move from the rotating table 33 onto the conveyor belt structure 3 for further operations.

[0073] Then the second motor 11 rotates in reverse, driving the first lead screw 10 to rotate in reverse, and then driving the first slider 12 to rotate back to the original position. At the same time, since the workbench 13 and the first slider 12 are elastically connected by a spring, during the process of the first slider 12 returning to the original position, the workbench 13 will be pulled back to the original position on the first slider 12 by the spring.

[0074] The above is only the preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
