Detailed Implementation

[0028] The following is in conjunction with the appendix Figures 1 to 7 The present invention will be described in detail.

[0029] This invention is mainly used for the automatic folding, forming, and unloading of paper drawer boxes. It typically features a single-opening, sealed-bottom rectangular cylindrical structure, thus having four sides and a sealed bottom surface. (Material reference...) Figure 7 .

[0030] An automatic drawer box forming device of the present invention includes a fixed frame 1, on which are sequentially arranged a receiving platform 11 for loading materials, a gripping device 12 for gripping materials from the receiving platform 11, a folding mechanism 2 for folding materials, a rotating device 3 for assisting in folding and transporting materials, and a discharging mechanism 4 for sealing the bottom and discharging materials. After the materials have been processed by other equipment such as cutting, creasing, and pasting, they are placed on the receiving platform 11. The gripping device 12 grips the materials and places them on the folding mechanism 2 to fold them into a rectangular tube shape. Then, the rotating device 3 transports the materials to the discharging mechanism 4 for sealing the bottom and discharging them. The entire process requires no manual operation and can realize fully automatic edge folding and bottom sealing of the drawer box during the folding and forming process.

[0031] The folding mechanism 2 includes a first folding device 21, a second folding device 22, a baffle a23 located below the first folding device 21, a baffle b24 located below the second folding device 22, and a lifting device a25. Each of the first folding device 21, the second folding device 22, the baffle a23, and the baffle b24 is equipped with a cylinder, allowing them to move. The rotating device 3 is equipped with symmetrically placed lifting devices b31 and c32, each with a fixed rod 38 for pressing and conveying material. Material is placed on the folding mechanism 2 by the gripping device 12. The first folding device 21, the second folding device 22, and the lifting device a25 support the material. Then, the rotating device 3 operates, controlling the fixed rods 38 to assist the folding mechanism 2 in folding the box.

[0032] Specifically, the first folding device 21 and the second folding device 22 are symmetrical to each other, and the lifting device a25 is provided with a support member 251. The fixing rod 38 of the lifting device b31 or the lifting device c32 moves downward to abut against the material, so that the side A1 of the material contacts the support member 251. At the same time, the lifting device a25 descends, and the material sinks with the support member 251. Then, the side B1 of the material contacts the baffle a23, the side C1 of the material contacts the baffle b24, the side D1 of the material contacts the first folding device 21, and the edge C2 of the material contacts the second folding device 22. After the lifting device a25 descends to a certain position, the first folding device 21 presses the side D1 of the material inward, and the second folding device 22 presses the edge C2 of the material inward, so that the edge of the side D1 of the material contacts the edge C2 of the material, thereby forming a rectangular tube shape.

[0033] The rotating device 3 has a rotary motor 33 at its bottom, a connecting plate 34 on its top, and side plates a35 and b36 on its sides. The lifting devices b31 and c32 are connected to side plates a35 and b36 respectively. In this technical solution, when the lifting device b31 approaches the folding mechanism 2, the lifting device c32 simultaneously approaches the discharging mechanism 4. The lifting devices b31 and c32 are symmetrical, and the rotary motor 33 can drive the lifting devices b31 and c32 to move between the folding mechanism 2 and the discharging mechanism 4, facilitating material transport.

[0034] The side plate a35 is provided with a first slide rail 351, the lifting device b31 is provided with a first slider 311 that cooperates with the first slide rail 351, the side plate b36 is provided with a second slide rail 361, and the lifting device c32 is provided with a second slider 321 that cooperates with the second slide rail 361. The cooperation between the slider and the slide rail improves the stability of the lifting device b31 and the lifting device c32, ensuring that the material will not shake or misalign during the movement of the lifting device b31 and the lifting device c32 driven by the rotary motor 33.

[0035] Both side plates a35 and b36 are equipped with servo motors 37, and the servo motors 37 are connected to screws 371. In this technical solution, the two servo motors 37 are respectively connected to lifting device b31 and lifting device c32. In addition, lifting device b31 and lifting device c32 are not at the same height. When lifting device b31 rises, lifting device c32 falls, and vice versa. This facilitates the simultaneous bottom sealing and material discharge operation of the material discharge mechanism 4 during the folding operation assisted by the rotating device 3 and the folding mechanism 2. The technical solution of this invention has extremely high folding and forming material discharge efficiency.

[0036] The discharge mechanism 4 includes a bottom sealing device 41 and a discharge device 42, wherein the bottom sealing device 41 is located directly below the discharge device 42. After the lifting device b31 drives the fixed rod 38 to cooperate with the folding mechanism 2 to process the material into a rectangular cylindrical shape, the lifting device a25 continues to descend. During this process, the fixed rod 38 gradually forms contact with the side D1 of the material from the side A1 of the material, so that the material is hung on the fixed rod 38. Then the rotating device 3 rotates, and the lifting device b31 transports the material to the bottom sealing device 41 for bottom sealing. At this time, the lifting device c32 moves above the folding mechanism 2. During the rotation of the rotating device 3, the gripping device 12 has placed new material on the folding mechanism 2. After the bottom sealing device 41 seals the rectangular cylindrical material hanging on the lifting device b31, the material hanging on the lifting device b31 has formed a folded box. Then, the servo motor 37 drives the lifting device b31 to rise and lift the material to the discharge device 42 for discharge. At the same time, the lifting device c32 descends and blocks the new material. During the process of the new material being processed into a rectangular cylindrical shape by the folding mechanism 2, the folded box material hanging on the lifting device b31 is grabbed and discharged by the discharge device 42. Then, the rotating device 3 rotates, causing the lifting device c32 to move the new rectangular cylindrical material to the bottom sealing device 41. This process is repeated. The automatic drawer box forming device of the present invention has a fast material conveying speed and greatly improves the folding box forming efficiency.

[0037] A limiting block 39 is provided between the lifting device b31, the lifting device c32 and the fixed rod 38. The limiting block 39 can restrict the position of the material hanging on the fixed rod 38. After the material is processed into a rectangular cylindrical shape, the edge of the opening abuts against the limiting block 39, which can improve the stability of the bottom sealing device 41 during the bottom sealing operation.

[0038] The bottom sealing device 41 is equipped with a fixing clamp 411, a side pushing device 412, and a first cylinder 414 that drives the fixing clamp 411 and the side pushing device 412 to move. The side pushing device 412 is equipped with a second cylinder 415 and a roller 413. The second cylinder 415 can drive the roller 413 to move. The fixing clamp 411 is used to fix the rectangular cylindrical material and fold the bottom surface A2 and bottom surface D3 of the material along the crease for the first bottom sealing. Then, the second cylinder 415 drives the roller 413 to contact the bottom surface B2 and bottom surface C2 of the material respectively, and fold the bottom surface B2 and bottom surface C2 of the material along the crease for the second bottom sealing. At this point, the material is folded into a box shape.

[0039] The discharge device 42 is equipped with a discharge window 421. A third cylinder 422 is positioned above the discharge window 421. A material hook 423, L-shaped, is attached to the end of the third cylinder 422 to catch the opening edge of the folded box material. The discharge device 42 also includes a fourth cylinder 424 that drives the third cylinder 422 to rise and fall. The fixing rod 38 hangs the folded box material at the position corresponding to the discharge window 421. The third cylinder 422 extends the material hook 423, the fourth cylinder 424 drives the third cylinder 422 to fall, and finally the third cylinder 422 retracts the material hook 423, causing the material hook to catch the opening edge of the material and transport the material to the discharge window 421 for discharge. The discharge speed is fast.

[0040] The discharge device 42 is equipped with a drive device 425, and a positioning clamp 426 is provided above the discharge window 421. The drive device 425 can drive the positioning clamp 426 to move. The positioning clamp 426 is also connected to a fifth cylinder 427. After the fixing rod 38 hangs the folded box-shaped material at the position corresponding to the discharge window 421, the drive device 425 and the fifth cylinder 427 drive the positioning clamp 426 to grab the material, making the material suspended in the air. This makes it easier for the material hook 423 to hook the opening edge of the material, preventing the material hook 423 from touching the limiting block 39 and the fixing rod 38, thus improving the stability of the discharge.

[0041] The receiving platform 11 is provided with a pressing device 13 at one end near the folding mechanism 2. The pressing device 13 can flatten the material, making it easier for the gripping device 12 to grip the material.

[0042] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
