Description

Technical Field

[0001] This utility model relates to the field of paper box production technology, and more specifically, to an environmentally friendly paper box folding mechanism. Background Technology

[0002] Cardboard boxes are widely used in many fields such as food, medicine, and electronic products due to their advantages such as being environmentally friendly, easy to process, and low in cost. During cardboard box production, to improve their overall aesthetics and recognizability, a face paper with printed patterns or text is usually glued to the outer wall of the box, which is made of grey cardboard. When the face paper is glued to the grey cardboard, one edge of it will be slightly longer than the grey cardboard to cover the opening of the box and prevent the grey cardboard from being exposed. After gluing, the protruding edge of the face paper needs to be folded inward, and then the two are pressed together to adhere the protruding part of the face paper to the inner wall of the grey cardboard.

[0003] Currently, this folding process mostly relies on manual operation. Manual folding is not only inefficient and difficult to meet the needs of large-scale production, but it also easily leads to problems such as skewed adhesion of the face paper and irregular creases. Moreover, simply relying on manual pressing cannot guarantee the adhesion strength between the face paper and the grey board paper, which can easily result in the face paper not adhering firmly. Therefore, this utility model proposes a new solution. Utility Model Content

[0004] The purpose of this invention is to solve the problem that most of the current folding process relies on manual operation. Manual folding is not only inefficient and difficult to meet the needs of large-scale production, but it is also prone to problems such as skewed bonding of the face paper and irregular creases. Moreover, relying solely on manual pressing cannot guarantee the bonding strength between the face paper and the grey board paper, which can easily lead to problems with the face paper not adhering firmly. Therefore, an environmentally friendly paper box folding mechanism is proposed.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An environmentally friendly cardboard box folding mechanism was developed to address the aforementioned issues.

[0007] The present invention is as follows:

[0008] The device includes a support frame, on the inner side of which a first table and a second table are mounted. A first conveying assembly is mounted on the top of the first table, and an upward-flipping assembly mounted on the side wall of the first table is provided on one side of the first conveying assembly. A fixing assembly that cooperates with the upward-flipping assembly is mounted on the top of the support frame. A pressing assembly is mounted on the top of the second table, and a second conveying assembly mounted on the top of the second table is provided on one side of the pressing assembly.

[0009] As a preferred technical solution of this utility model, both the first conveying assembly and the second conveying assembly include two symmetrically arranged first side plates, and a first conveying roller and a second conveying roller symmetrically arranged are rotatably installed between the two first side plates. One side of one of the first side plates is provided with a motor for driving the second conveying roller to rotate.

[0010] As a preferred technical solution of this utility model, both ends of the first conveying roller are rotatably connected to a first slider that is slidably installed inside the first groove, and the top of the first side plate is threadedly connected to a first adjusting screw whose bottom end is inserted into the first groove, and the bottom end of the first adjusting screw is rotatably connected to the top of the first slider.

[0011] As a preferred technical solution of this utility model, the extrusion assembly includes two second side plates symmetrically installed on the top of the second platform, an extrusion roller is provided between the two second side plates, and a second slider is rotatably installed at both ends of the extrusion roller and slidably connected to the second side plate through a second sliding groove. A second adjusting screw with its bottom end inserted into the second sliding groove is threadedly connected to the top of the second side plate, and the bottom end of the second adjusting screw is rotatably connected to the top end of the second slider.

[0012] As a preferred technical solution of this utility model, the fixing component includes a mounting plate installed on the top of the bracket, a first cylinder is installed on the top of the mounting plate, the moving end of the first cylinder is connected to a pressure plate located below the mounting plate, and a guide rod that is slidably connected to the mounting plate is installed on the top of the pressure plate.

[0013] As a preferred technical solution of this utility model, the flip-up component includes a mounting frame fixedly installed on the first table surface, a second cylinder fixedly installed on the top of the mounting frame, and a folding plate installed on the moving end of the second cylinder.

[0014] As a preferred technical solution of this utility model, the side wall of the first table surface is symmetrically provided with grooves located on both sides of the folded edge plate. A guide rail is fixedly installed inside the groove, and a third slider is slidably installed on the guide rail. A connecting piece for connecting the third slider is installed on the side wall of the mounting bracket.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In the solution of this utility model:

[0017] 1. By setting up a first table, a fixing component, and an upward folding component, when folding the face paper, first align the edge of the gray board paper with the edge of the first table, and then fix it with the fixing component. At this time, activating the upward folding component will fold the part of the face paper protruding from the gray board paper upward as a whole, which can ensure neat creases and avoid the face paper from being crooked. Moreover, it is faster than manual folding and can effectively improve the production speed of paper boxes.

[0018] 2. By setting up a squeezing component and a second conveying component, the folded grey cardboard will pass through the squeezing component under the conveying of the first conveying component during use. During the process of passing through the squeezing component, the squeezing component will press down the face paper that has been folded up to be perpendicular to the grey cardboard, so that the face paper is firmly attached to the inner wall of the grey cardboard. At the same time, during the process of the grey cardboard passing through the second conveying component, the second conveying component will also squeeze the grey cardboard and the face paper a second time, thereby avoiding the problem of the face paper not adhering firmly.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0029] like Figures 1-7 As shown, this embodiment proposes an environmentally friendly cardboard box folding mechanism, including a support 1. A first platform 2 and a second platform 3 are installed on the inner side of the support 1. A first conveying component 4 is installed on the top of the first platform 2. An upward-flipping component 8 is installed on one side of the first conveying component 4 and mounted on the side wall of the first platform 2. A fixing component 5 that cooperates with the upward-flipping component 8 is installed on the top of the support 1. By setting the first platform 2, the fixing component 5, and the upward-flipping component 8, when folding the face paper, the edge of the gray board paper is first aligned with the edge of the first platform 2, and then fixed by the fixing component 5. At this time, activating the upward-flipping component 8 can fold the part of the face paper protruding from the gray board paper upward as a whole, which can ensure neat creases and avoid crooked face paper adhesion. The folding is faster than manual folding, which can effectively improve the production speed of paper boxes. The top of the second table 3 is equipped with a pressing component 6, and a second conveying component 7 is installed on one side of the pressing component 6. By setting the pressing component 6 and the second conveying component 7, the gray cardboard that has been folded up will pass through the pressing component 6 under the conveying of the first conveying component 4. During the process of passing through the pressing component 6, the pressing component 6 will press down the face paper that has been folded up to be perpendicular to the gray cardboard, so that the face paper is firmly attached to the inner wall of the gray cardboard. At the same time, during the process of the gray cardboard passing through the second conveying component 7, the second conveying component 7 will also perform secondary pressing on the gray cardboard and the face paper, thereby avoiding the problem of the face paper not adhering firmly.

[0030] like Figure 1 , Figure 3 and Figure 6As shown, in a preferred embodiment, based on the above method, both the first conveying assembly 4 and the second conveying assembly 7 include two symmetrically arranged first side plates 401. A first conveying roller 402 and a second conveying roller 403 are rotatably mounted between the two first side plates 401. One side of one of the first side plates 401 is provided with a motor 404 for driving the second conveying roller 403 to rotate. Both ends of the first conveying roller 402 are rotatably connected to a first slider 406 that is slidably installed inside the first slide groove 407. The top of the first side plate 401 is threadedly connected to a first adjusting screw 405 whose bottom end is inserted into the first slide groove 407. The bottom end of the first adjusting screw 405 is rotatably connected to the top of the first slider 406. It should be noted that during use, the motor 404 can drive the second conveyor roller 403 to rotate, thereby cooperating with the first conveyor roller 402 to convey the gray board paper located between the two. By rotating the first adjusting screw 405, the height position of the first slider 406 can be adjusted, thereby adjusting the distance between the first conveyor roller 402 and the second conveyor roller 403, so as to facilitate the use of gray board paper of different thicknesses.

[0031] like Figure 1 and Figure 7 As shown, in a preferred embodiment, based on the above method, the extrusion assembly 6 further includes two second side plates 601 symmetrically installed on the top of the second platform 3. An extrusion roller 602 is provided between the two second side plates 601. Both ends of the extrusion roller 602 are rotatably mounted with second sliders 603 that are slidably connected to the second side plates 601 via second grooves 605. The top of the second side plate 601 is threadedly connected to a second adjusting screw 604 whose bottom end is inserted into the second groove 605. The bottom end of the second adjusting screw 604 is rotatably connected to the top end of the second slider 603. It should be noted that when the grey board paper passes under the extrusion roller 602, the extrusion roller 602 will press the face paper perpendicular to the grey board paper towards the grey board paper, causing the face paper to adhere to the inner wall of the grey board paper. By rotating the second adjusting screw 604, the distance between the extrusion roller 602 and the top of the second platform 3 can be adjusted via the second sliders 603, facilitating adjustment of the extrusion roller 602 according to the thickness of different grey board papers.

[0032] like Figure 1 and Figure 5As shown, in a preferred embodiment, based on the above method, the fixing component 5 further includes a mounting plate 501 mounted on the top of the bracket 1. A first cylinder 502 is mounted on the top of the mounting plate 501. The moving end of the first cylinder 502 is connected to a pressure plate 503 located below the mounting plate 501. A guide rod 504, which is slidably connected to the mounting plate 501, is mounted on the top of the pressure plate 503. It should be noted that when the face paper is folded, the first cylinder 502 is activated to drive the pressure plate 503 to descend, pressing the gray board paper firmly against the top of the first table surface 2, thereby preventing the gray board paper from moving during the face paper folding process.

[0033] like Figures 1-4 As shown, in a preferred embodiment, based on the above method, the upward-folding component 8 further includes a mounting bracket 801 fixedly mounted on the first tabletop 2. A second cylinder 802 is fixedly mounted on the top of the mounting bracket 801, and a folding plate 803 is mounted on the moving end of the second cylinder 802. Grooves 9 are symmetrically formed on the sidewall of the first tabletop 2 on both sides of the folding plate 803. A guide rail 10 is fixedly mounted inside the groove 9, and a third slider 11 is slidably mounted on the guide rail 10. A connecting piece 12 for connecting the third slider 11 is mounted on the sidewall of the mounting bracket 801. It should be noted that when folding, the second cylinder 802 is activated to drive the folding plate 803 to slide upward along the sidewall of the first tabletop 2, thereby folding the face paper parallel to the gray board paper to a position perpendicular to the gray board paper. The guide rail 10, the third slider 11, and the connecting piece 12 facilitate the guidance of the sliding folding plate 803, making it more stable during movement.

[0034] Specifically, the working principle of this environmentally friendly paper box folding mechanism is as follows: When folding, the gray board paper with the face paper pasted on is passed through the inside of the first conveying component 4, so that the edge of the gray board paper is parallel to the side wall of the first table 2. Then, the second cylinder 802 is activated to drive the folding plate 803 to slide upward along the side wall of the first table 2, thereby flipping the face paper parallel to the gray board paper to a state perpendicular to the gray board paper. At this time, the first conveying component 4 is activated to convey the gray board paper to the pressing component 6. When the gray board paper passes under the pressing roller 602, the pressing roller 602 will press the face paper perpendicular to the gray board paper towards the gray board paper, so that the face paper is pasted to the inner wall of the gray board paper. The two after being pressed and pasted will be conveyed out through the second conveying component 7.

[0035] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
