Description

Technical Field

[0001] This invention relates to a folding mechanism for transforming flattened packaging paper into a three-dimensional packaging box. The invention also relates to an apparatus that allows for continuous operation of folding and labeling. Background Technology

[0002] Existing filter cartridge packaging boxes are typically obtained by opening and folding flattened cardboard boxes. For example... Figure 1 and Figure 2 As shown, the packaging box 100 includes a main body 1a and a first folded corner piece 11a, a second folded corner piece 12a, a third folded corner piece 13a, and a fourth folded corner piece 14a located at the rear end of the main body 1a. The main body 1a is formed by four surfaces, with creases between the surfaces and between the main body 1a and each of the folded corner pieces. Figure 3 As shown, the first folding piece 11a is opposite to the second folding piece 12a, and the third folding piece 13a is opposite to the fourth folding piece 14a. The first folding piece 11a has a first protrusion 111a on both sides of its front end, and a slot 112a is formed between the first protrusions 111a. The second folding piece 12a has a second protrusion 121a in the middle of its front end. The third folding piece 13a includes a first narrow portion 131a with an inclined edge and a first wide portion 132a located at the lower end of the first narrow portion 131a. The structure of the fourth folding piece 14a is similar to that of the third folding piece 13a, including a second narrow portion 141a with an inclined edge and a second wide portion 142a located at the lower end of the second narrow portion 141a.

[0003] like Figure 3 As shown, after the packaging box is opened, the surfaces of the main body 1a form a 90° angle, creating a three-dimensional structure. When folding the box, first bend the first corner piece 11a 90° along the crease, then bend the third corner pieces 13a and the fourth corner pieces 14a on both sides 90° along the crease, and finally bend the second corner piece 12a 90° along the crease. The second protrusion 121a of the second corner piece 12a is inserted into the slot 112a formed between the first protrusions 111a, completing the folding process and transforming the box into a packaging box. The folded box is as follows: Figure 4 As shown.

[0004] Currently, box folding and unfolding are mostly done manually. This results in high breakage rates, low efficiency, and low automation, all of which need improvement. Furthermore, labeling and box folding are performed separately, leading to overall low work efficiency. Summary of the Invention

[0089] A conveyor belt 102 is provided below the labeling mechanism 101. Rollers 103 are provided on both sides of the conveyor belt 102, which can rotate.

[0090] The work rack 10 is equipped with an air blowing mechanism 7 near the labeling mechanism 101, which can flatten the labels affixed to the packaging boxes.

The air inlet end of the air pipe 71 can be connected to an external air source, and the air nozzle 72 is located at the air outlet end of the air pipe 71.

[0091] The working principle is as follows:

[0092] During the feeding process, the lifting cylinder 11 rises, causing the top plate and suction cup 17 to move upwards. The suction cup 17 then picks up the packaging paper 100 from the bottom (e.g., ...). Figure 1 As shown), the lifting cylinder 11 descends to the area of ​​the work frame 10 where the packaging paper is placed; the suction cup detaches from the packaging paper, completing the feeding.

[0093] During the folding process, the first support rod 311 on the first cylinder 31 is in the extended state, the contact block 32 abuts against the inner wall of the first folding piece 11a, the packaging paper opens, the first support rod 311 descends, the clamping cylinder 21 is activated, and the clamping plate assembly 2 clamps the packaging paper; the packaging paper becomes attached Figure 2 The packaging box is in a three-dimensional state. When the second cylinder 41 operates, the first pressing element 42 flips and acts on the outer wall of the second corner piece 12a, causing the second corner piece 12a to flip upwards. Subsequently, the first drive assembly 30 operates, and the first rotary cylinder 33 drives the swing rod 34 to rotate. The swing rod 34 acts on the lower end of the third corner piece 13a. Simultaneously, the sixth cylinder 35 operates, and the contact block 36 acts on the upper end of the third corner piece 13a, causing the third corner piece 13a to bend inwards. The second drive assembly 30a operates, and the seventh cylinder 37 drives the ball head 371 to extend, and the ball head 371 acts on the fourth corner piece. The outer wall of 14a, the fourth folding piece 14a bends inward; the third cylinder 51 actuates, driving the pressure rod 521 to flip and act on the outer wall of the first folding piece 11a, causing the first folding piece 11a to bend inward; the fourth cylinder 38 actuates, the contact block 381 continues to act on the outer wall of the first folding piece 11a, causing the first folding piece 11a to bend further inward from the vertical direction, so that the two first protrusions 111a of the first folding piece 11a can be respectively inserted into the first narrow part 131a of the third folding piece and the second narrow part 141a of the fourth folding piece, forming as shown in the figure. Figure 14 In this state, slot 112a is fitted with the second protrusion, and the four corner pieces arch slightly inward. Then, drive cylinder 15 is activated, one side of the support plate 13 is raised, the packaging box is tilted, the fifth cylinder 39 is activated, and the second push rod drives the packaging box forward to enter the conveyor belt 102.

[0094] The labeling process, such as Figure 11 and Figure 12As shown, when the labeling cylinder 62 is activated, the connecting plate 63 drives the label suction plate 64 to move forward, sucking up the label sheet 104 from the label supply mechanism 8. The labeling cylinder 62 then retracts, and the second rotary cylinder 61 drives the labeling cylinder 62 to rotate 90° (as shown). Figure 15 As shown, the labeling cylinder 62 extends to stick the label to the outer wall of the packaging box. At the same time, the air blowing mechanism 7 works to blow the label flat. The air blowing direction of the air blowing mechanism 7 is from front to back, which is opposite to the running direction of the conveyor belt 102.

[0095] Finally, after stuffing the product into the packaging box, flatten the four inward-arching corner pieces, and then seal the packaging box.
