Detailed Implementation

[0033] The present invention will be further described in detail below with reference to embodiments:

[0034] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0035] like Figures 1 to 10As shown, an automatic color box bonding forming device is provided, capable of folding color box cardboard 100. The color box cardboard 100 includes a body 101 and a first connecting plate 102 and a second connecting plate 103 located on both sides of the body 101. The first connecting plate 102 and the body 101 have a first fold line 104, and the second connecting plate 103 and the body 101 have a second fold line 105. The first connecting plate 102 is provided with a glue-applying area 1021 for applying glue. The device further includes: a continuously arranged first transport line 1; a second transport line 2, disposed on the first transport line 1, and located above the first transport line 1, so that a clamping gap capable of positioning the body 101 is formed between the second transport line 2 and the first transport line 1; and a glue-applying device 3, disposed on the side of the first transport line 1 and located below the path of the color box cardboard 100, the glue-applying device 3 being able to apply glue to the first connecting plate 102 as the color box cardboard 100 passes through. The gluing area 1021 on the connecting plate 102 is coated with glue; the bending device 4 is disposed on the first transport line 1 and located behind the gluing device 3. The bending device 4 includes a first bending plate 41 and a second bending plate 42 disposed along the moving direction of the first transport line 1. The first bending plate 41 and the second bending plate 42 are disposed on both sides of the first transport line 1, and the first bending plate 41 and the second bending plate 42 are arranged progressively so that when the color box cardboard 100 passes through, the first connecting plate 102 is bent into a straight line. The connecting plate 102 can be folded gradually from the outside to the inside relative to the main body 101 along the first fold line 104, so that the glue application area 1021 is facing upward. The second connecting plate 103 can be folded gradually from the outside to the inside relative to the main body 101 along the second fold line 105 and cover the top of the first connecting plate 102. The pressing device 5 is located on the rear side of the first transport line 1 and can press the first connecting plate 102 and the second connecting plate 103 together after being bent by the bending device 4.

[0036] When the color box cardboard 100 needs to be processed into a color box, the color box cardboard 100 is placed on the first transport line 1. The color box cardboard 100 moves along a predetermined direction and gradually passes through the second transport line 2. When the first connecting plate 102 passes through the glue applicator 3, the glue applicator 3 applies glue to the glue applicator area 1021 of the first connecting plate 102. The color box cardboard 100 continues to move. At this time, the first connecting plate 102 and the second connecting plate 103 contact the first bending plate 41 and the second bending plate 42 respectively. Under the guidance of the first bending plate 41 and the second bending plate 42, the first bending plate 41 gradually moves from the outside to the inside along the first fold line 104 relative to the body 101. When folded to the side, the first bending plate 41 is located above the main body 101, and the glue application area 1021 is set upward. The second connecting plate 103 can be folded gradually from the outside to the inside relative to the main body 101 along the second fold line 105 and cover the first connecting plate 102. Part of the second connecting plate overlaps with the glue application area 1021. Then, through the pressing device 5, the first connecting plate 102 and the second connecting plate are bonded together to form a shape. The user only needs to place the color box cardboard 100 to complete the forming of the color box cardboard 100. It is very convenient to use. Compared with manual glue application and pressing, it is more accurate, can reduce the generation of defective products, and is more efficient.

[0037] Of course, one can think of using robotic arms and other equipment to achieve 100% automatic feeding of color box cardboard, which would be more convenient.

[0038] The bending device 4 further includes baffles 43 disposed on both sides of the second transport line 2 to prevent the first connecting plate 102 and the second connecting plate 103 from folding inward as they pass through the second transport line 2. The baffles 43 prevent the first connecting plate 102 and the second connecting plate 103 from folding inward and coming into contact with the second transport line 2, thus avoiding affecting their appearance and preventing damage to the first connecting plate 102 and the second connecting plate 103.

[0039] The second bending plate 42 is disposed behind the first bending plate 41, so that when the color box cardboard 100 is folded, the second connecting plate 103 can be folded along the second fold line 105 and cover the first connecting plate 102. This arrangement allows the first connecting plate 102 to fold inward first, ensuring that the second connecting plate 103 can fold backward, so that the second connecting plate is located above the first connecting plate 102, ensuring precise bonding between the two.

[0040] The bending device 4 further includes a connecting seat 44 disposed on the first transport line. The connecting seat is also provided with a shaping rod 45. The shaping rod 45 is used to push the second connecting plate when the second connecting plate 103 is bent relative to the plate body to approximately a right angle, causing the second connecting plate to fold inward along the second fold line 105. The shaping rod 45 is positioned such that the second connecting plate is at a right angle or nearly a right angle to the body 101, pushing the outer side xx of the second connecting plate, causing the second connecting plate to fold inward along the second fold line 105.

[0041] The front end of the shaping rod 45 is arc-shaped, and the rear side of the shaping rod 45 approaches the top surface of the first transport line 1, thus forming a forming gap between them. The arc-shaped front end of the shaping rod 45 facilitates guidance, and the approach of the rear side of the shaping rod 45 to the top surface of the first transport line 1 allows the second connecting plate 103 to fit against the first connecting plate 102, facilitating subsequent pressing operations.

[0042] The first connecting plate 102 and the second connecting plate 103 include a first bending segment D1 and a second bending segment D2. The inclination angle of the first bending segment D1 gradually increases from 0° to 90°. The second bending segment D2 is connected to the first bending segment D1, and the inclination angle of the second bending segment D2 gradually increases from 90° to approximately 0°. This arrangement allows the outer surface A of the first connecting plate 102 to bend from a downward position to a 90° angle, and then bend inward from that position, at which point the outer surface A is facing upward. Similarly, the outer surface B of the second connecting plate 103 is bent from a downward position to a 90° angle, and then bends inward from that position, at which point the outer surface B is facing upward. The inner surface C of the second connecting plate 103 and the outer surface A of the first connecting plate 102 can then be glued together.

[0043] Both baffles 43 are provided with rearwardly extending extension plates 46. The sides of the extension plates 46 are provided with supporting surfaces 461. When the color box cardboard 100 is folded, the supporting surfaces 461 of the extension plates 46 can abut against the first fold line 104 and the second fold line 105. The extension plates 46 guide the folding of the color box cardboard 100, preventing misalignment when the first connecting plate 102 and the second connecting plate 103 are folded inward, thus affecting the adhesion between the first connecting plate 102 and the second connecting plate 103. The supporting surfaces 461 abut against the first fold line 104 and the second fold line 105 for precise positioning.

[0044] The glue application device 3 includes a glue box 31, on which a first roller 32 is provided. When the first roller 32 rolls, it applies glue to the first connecting plate 102. The glue application device 3 also includes a stand 33, on which a second roller 34 is rotatably connected. The second roller 34 and the first roller 32 are used to position the first connecting plate 102, so that the first roller can stably and evenly apply glue to the first connecting plate 102.

[0045] The pressing device 5 is further provided with a third transport line 6 at its rear. The third transport line 6 is used to deliver the completed color box to the outside.

[0046] The pressing device 5 includes a connecting frame 51, on which a first pressure roller 52 and a second pressure roller 53 are arranged vertically. A roller gap is formed between the first pressure roller 52 and the second pressure roller 53. The connecting frame 51 is also provided with a driving member 54 that can drive the first pressure roller 52 or the second pressure roller 53 to roll. The first pressure roller 52 and the second pressure roller 53 cooperate to press the first connecting plate 102 and the second connecting plate 103 together. Due to the glue, the first connecting plate 102 and the second connecting plate 103 are connected.

[0047] The first transport line 1 is also equipped with a shelf 71 that can rotate relative to it at its front end. The first transport line 1 is also equipped with a cylinder 72, the output shaft of which is connected to the bottom end of the shelf 71. The angle of inclination of the shelf 71 relative to the first transport line 1 is controlled by the output shaft of the cylinder 72, which makes it easier for the user to place the color box cardboard 100.

[0048] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
