Description

Technical Field

[0001] The present invention belongs to the technical field of packaging box processing, and specifically relates to a semi-automatic water-based glue edge folding and bubble pressing packaging box machine and its operation method. Background Art

[0002] Packaging boxes are widely used in daily life. Packaging boxes can be used for packaging or storing items and are one of the essential items in people's daily life and work.

[0003] In order to make the packaging box look more beautiful, usually a packaging paper material is pasted on the outside of the packaging box through water-based glue. The style and material of the material can be selected according to actual needs. After the material is pasted on the packaging box through water-based glue, there may be air bubbles between the material and the packaging box. It is necessary to remove the air bubbles between the material and the packaging box and perform edge folding and compaction operations on the edge of the material. As Figure 1 shown, it is a schematic diagram of the material pasted on the packaging box.

[0004] Currently, the bubble pressing and edge folding operations are mostly carried out manually. Workers use wooden sticks or toothpicks to manually scrape off air bubbles and perform edge folding and compaction operations. Manual operation not only has low efficiency, but also places a large load on the workers' hands, increasing the workload of the workers. Moreover, during the process of manually scraping off air bubbles and performing edge folding and compaction operations, manual operation may accidentally scrape out scratches, damaging the material on the surface of the packaging box and causing waste of materials. Summary of the Invention

This process does not require workers to manually use wooden sticks or toothpicks to scrape off air bubbles and perform edge folding and compaction operations, which not only reduces the workload of the workers, but also improves the work efficiency. At the same time, it can also avoid the possibility of accidentally scraping out scratches due to manual operation, reduce the material loss rate, and improve the qualified rate and quality of the product.

[0045] Above the bearing plate 11, there are a first limiting plate 14 and a second limiting plate 15. The second limiting plate 15 is placed below the first limiting plate 14.

The lower surface of the bearing plate 11 is fixedly connected with a plurality of first support rods 111, and the lower surface of the first support rods 111 is fixedly connected with a first connecting plate 112.

[0046] The bearing plate 11 is provided with a reserved hole 113, and the first limiting plate 14 and the second limiting plate 15 are placed above the reserved hole 113. The upper surface of the first connecting plate 112 is fixedly connected with a plurality of second support rods 1121. The second support rods 1121 pass through the reserved hole 113 and are fixedly connected with the lower surface of the first limiting plate 14. The second support rods 1121 pass through the second limiting plate 15. The upper surface of the first connecting plate 112 is fixedly connected with a plurality of third support rods 1122.

[0047] The upper surface of the first connecting plate 112 is fixedly connected with a fourth support rod 1123, and the top of the fourth support rod 1123 is fixedly connected with a bottom fixing plate 11231. Below the second limiting plate 15, there is a second pressing plate 16. The upper surface of the second pressing plate 16 is provided with a second compaction part 161. The second compaction part 161 is placed in the second limiting hole 151. The bottom fixing plate 11231 passes through the second compaction part 161, and the second pressing plate 16 can pass through the reserved hole 113. The first connecting plate 112 is connected with a second driving mechanism 3, and the second driving mechanism 3 can drive the second pressing plate 16 to move in the vertical direction.

[0048] Above the bearing plate 11, there are three third pressing plates 17. The third pressing plates 17 are placed between the first limiting plate 14 and the second limiting plate 15, and the three third pressing plates 17 are arranged at intervals of 90° in sequence. A shovel plate 171 is respectively abutted against the top and bottom of each third pressing plate 17. Each third pressing plate 17 is connected with a third driving mechanism 4, and the third driving mechanism 4 can respectively drive the third pressing plate 17 and the shovel plate 171 to move in the horizontal direction.

[0049] Above the carrier plate 11, there is a fourth pressure plate 18. The space enclosed by the fourth pressure plate 18 and the three third pressure plates 17 is the accommodation cavity 5. On the side of the fourth pressure plate 18 close to the accommodation cavity 5, there is a third compaction part 181. The fourth pressure plate 18 is connected to a fourth driving mechanism 6, and the fourth driving mechanism 6 drives the fourth pressure plate 18 to move in the horizontal direction.

[0050] When it is necessary to press the bubbles of the packaging box, the packaging box is placed into the accommodation cavity 5 through the first limiting hole 141. The bottom fixing plate 11231 abuts against the lower surface of the packaging box, and the bottom fixing plate 11231 supports the wrapping paper. The third driving mechanism 4 drives the third pressure plate 17 to move towards the side close to the packaging box, and the fourth driving mechanism 6 drives the fourth pressure plate 18 to move towards the side close to the packaging box. The third pressure plate 17 and the fourth pressure plate 18 clamp the packaging box, initially squeezing out the bubbles between the wrapping material and the packaging box. The third compaction part 181 on the fourth pressure plate 18 is inserted into the interior of the packaging box, and the third compaction part 181 is in close contact with the inner wall of the packaging box, compacting the edge of the wrapping material folded into the interior of the packaging box.

[0051] After the third pressure plate 17 and the fourth pressure plate 18 clamp the packaging box, the first driving mechanism 2 first drives the top fixing plate 12 to descend, and the top fixing plate 12 presses the top of the packaging box to tightly fix the packaging box. The third driving mechanism 4 drives the shovel plate 171 to move towards the side close to the packaging box. The shovel plate 171 levels the upturned part of the wrapping material on the upper and lower surfaces of the packaging box to complete the edge folding operation, and the shovel plate 171 presses the edge of the wrapping material. The first driving mechanism 2 drives the first pressure plate 13 to descend, so that the first compaction part 131 presses the shovel plate 171 located above. The second driving mechanism 3 drives the second pressure plate 16 to move upwards, so that the second compaction part 161 presses the shovel plate 171 located below. The first compaction part 131 and the second compaction part 161 press the shovel plate 171, making the edge of the wrapping material fit more closely with the packaging box. After the first compaction part 131 and the second compaction part 161 press for a period of time, the third driving mechanism 4 drives the shovel plate 171 to move away from the packaging box, so that the shovel plate 171 leaves the packaging box.

In this process, it is not necessary for the staff to manually use wooden sticks or toothpicks to scrape the bubbles and perform the operations of folding and compacting the edges. This not only reduces the labor intensity of the staff, but also improves the work efficiency. At the same time, it can also avoid the possibility of accidentally scratching due to manual operation, reduce the loss rate of materials, and improve the qualification rate and quality of products.
