Description

Technical Field

[0001] This utility model relates to the field of paper box production technology, specifically to paper box forming equipment for the paper box packaging feeding section. Background Technology

[0002] In the modern commodity packaging industry, paper boxes are widely used in the packaging of many fields such as food, medicine, and daily necessities due to their advantages such as being lightweight, environmentally friendly, and easy to process. The production of paper boxes usually involves multiple processes such as paperboard cutting, conveying, and forming. Among them, the paperboard conveying and forming in the feeding section are the key links that affect the production efficiency and quality of paper boxes.

[0003] Currently, the production of cardboard packaging relies heavily on automated equipment. Cardboard is typically transported to the cardboard forming machine via a conveyor belt. However, in actual production, due to the inherent characteristics of the cardboard (such as its thinness and susceptibility to deformation), slight vibrations during conveyor operation, and dimensional differences between different batches of cardboard, the cardboard is prone to lateral shifting while being conveyed on the conveyor belt. Once the cardboard shifts, it may not only detach from the conveyor belt, causing material waste and production interruption, but it may also result in inaccurate positioning of subsequent cardboard entering the cardboard forming machine. This, in turn, affects the forming accuracy of the cardboard, leading to quality problems such as dimensional deviations and irregular corner folds, thus increasing the rate of defective products.

[0004] To address the issue of cardboard conveying misalignment, some production equipment incorporates simple guiding structures, such as fixed baffles. However, these fixed guiding structures cannot be adjusted according to the actual dimensions of the cardboard. When producing different sizes of cardboard boxes, different guiding components need to be replaced, which is cumbersome and time-consuming, severely impacting production continuity and flexibility. This makes it difficult to meet the high-efficiency, multi-variety production demands of modern production lines. Therefore, we propose a cardboard box forming equipment for the cardboard packaging feeding section. Utility Model Content

[0005] The purpose of this utility model is to provide a paper box forming equipment for the feeding section of paper box packaging. By setting a guiding mechanism, it solves the problem that the cardboard is prone to deviation or even separation from the conveyor belt when it is conveyed on the conveyor belt, which affects the subsequent paper box forming.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A paper box forming device for a paper box packaging feeding section includes a work plate, several support columns are mounted on the bottom surface of the work plate, and a conveyor body is mounted on the top surface of the work plate. The conveyor body includes two mounting plates fixed to the top surface of the work plate, a conveyor belt installed between the two mounting plates, and the paper box forming machine body is mounted on the top surface of the two mounting plates. The device also includes:

[0008] A guiding mechanism, set on the top surface of the work plate, is used to guide the cardboard on the top surface of the conveyor belt. The guiding mechanism includes a frame fixed on the top surface of the work plate, two movable rods slidably connected to the bottom surface of the horizontal plate end of the frame, a bidirectional lead screw rotatably connected between the two vertical plates of the frame and used to drive the two movable rods to move in opposite directions, and a guide motor installed on the outer wall of the frame and used to drive the bidirectional lead screw to rotate. Guide plates are installed on the outer walls of the two movable rods.

[0009] In a preferred embodiment, the frame is fixed to the top surface of the work plate near the middle position, the frame is arranged from front to back, and the horizontal plate end of the frame is located above the conveyor belt.

[0010] In a preferred embodiment, the guiding mechanism further includes two rotating columns that are rotatably connected to the two vertical plate ends of the frame, the bidirectional lead screw is coaxially fixed between the two rotating columns and arranged from front to back, the guiding motor is installed on the surface of one of the vertical plate ends of the frame away from the bidirectional lead screw, the output shaft of the guiding motor is coaxially connected to the rotating column on the same side, and the two moving rods are threadedly connected to the outer circumference of the bidirectional lead screw in a mutually symmetrical manner.

[0011] In a preferred embodiment, the movable rod is L-shaped, and the bottom surface of the horizontal plate end of the frame is provided with a limiting groove arranged from front to back, and the top surface of the vertical rod end of the movable rod is fixed with a limiting block that is slidably connected to the limiting groove on the bottom surface of the horizontal plate end of the frame.

[0012] In a preferred embodiment, the longitudinal cross-sectional shape of the upper limit groove on the bottom surface of the frame horizontal plate is I-shaped, and the shape of the limiting block is I-shaped to match the shape of the upper limit groove on the bottom surface of the frame horizontal plate.

[0013] In a preferred embodiment, the guide plate is fixed on the outer wall of the same side of the horizontal bar end of the moving rod away from the same side of the vertical plate end of the frame, and the bottom surface of the guide plate and the top surface of the conveyor belt are on the same plane.

[0014] In a preferred embodiment, a protective plate is installed on the opposite sides of both guide plates. The shape of the protective plate is adapted to the shape of the guide plate, and the thickness of the protective plate is between 10mm and 15mm.

[0015] These six features enable the guiding mechanism to precisely act on the cardboard on the conveyor belt, ensuring effective guidance; allow the guiding motor to stably drive the bidirectional lead screw to rotate, causing the two moving rods to move symmetrically in opposite directions, ensuring precise and stable adjustment of the guide plate spacing; make the moving rods slide more stably, preventing guide plate wobbling and improving guiding accuracy; prevent the moving rods from easily detaching from the frame during sliding, further enhancing the stability of the guiding mechanism; ensure the guide plate fully conforms to the side of the cardboard, guaranteeing the guiding effect; prevent cardboard conveying from being obstructed; and prevent the edges of the cardboard from being worn during the guiding process, protecting the integrity of the cardboard.

[0016] In a preferred embodiment, a plurality of support columns at the bottom of the working plate are arranged in a matrix, and a support plate is fixed at the bottom of the support column, and the bottom surface of the support plate is provided with anti-slip texture.

[0017] This feature makes the equipment more stable and less prone to shaking during operation, reducing deviations in cardboard delivery caused by vibration.

The entire process is closely connected, greatly improving the production efficiency of cardboard boxes, while reducing manual intervention and minimizing errors that may be caused by manual operation.

[0020] 2. This utility model achieves precise guidance of the cardboard conveyed on the top surface of the conveyor belt in the conveyor body through the setting of the guiding mechanism, and achieves the effect of flexibly adjusting the guiding distance according to the cardboard size and preventing cardboard conveying deviation; the guide motor drives the bidirectional lead screw to rotate, so that the two moving rods drive the guide plates to move in opposite directions, thereby flexibly adjusting the guide plate distance to adapt to cardboard of different sizes; at the same time, the moving rods are slidably connected to the limiting groove on the bottom surface of the frame horizontal plate through the limiting block to ensure stable and reliable movement. In addition, the protective plate installed on the opposite side of the guide plate effectively avoids the wear of the cardboard edge by the guide plate, further ensuring the conveying quality of the cardboard.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-2 The present invention provides a technical solution: a paper box forming equipment for the feeding section of a paper box packaging, including a working plate 1, a plurality of support columns 11 installed on the bottom surface of the working plate 1, a conveyor body 2 installed on the top surface of the working plate 1, the conveyor body 2 including two mounting plates 21 fixed on the top surface of the working plate 1, a conveyor belt 22 installed between the two mounting plates 21, and a paper box forming machine body 3 installed on the top surface of the two mounting plates 21.

[0030] Through the coordinated arrangement of the working plate 1, support column 11, conveyor body 2, and cardboard box forming machine body 3, the equipment can continuously complete the cardboard transmission and forming operations.

[0031] In this embodiment, a number of support columns 11 at the bottom of the working plate 1 are arranged in a matrix, and a support plate 12 is fixed at the bottom of the support column 11. The bottom surface of the support plate 12 is provided with anti-slip texture.

[0032] The matrix arrangement of support columns 11, the bottom support plate 12, and the anti-slip texture on the bottom surface ensure that the equipment is placed stably and is not easy to shake during operation, reducing the deviation of cardboard conveying caused by vibration and providing a solid foundation for stable operation of the equipment.

[0033] like Figure 1 , Figures 3-5 As shown, in addition to the above, it also includes: a guide mechanism 4, which is set on the top surface of the work plate 1 and is used to guide the cardboard on the top surface of the conveyor belt 22. The guide mechanism 4 includes a frame 41 fixed on the top surface of the work plate 1, two moving rods 44 slidably connected to the bottom surface of the horizontal plate end of the frame 41, a bidirectional lead screw 43 rotatably connected between the two vertical plate ends of the frame 41 and used to drive the two moving rods 44 to move in opposite directions, and a guide motor 46 installed on the outer wall of the frame 41 and used to drive the bidirectional lead screw 43 to rotate. Guide plates 47 are installed on the outer walls of the two moving rods 44.

[0034] The frame 41 and moving rod 44 of the guiding mechanism 4 work together to adjust the distance between the two guide plates 47 according to the size of the cardboard, effectively preventing deviation and ensuring stable transmission.

[0035] Furthermore, the frame 41 is fixed to the top surface of the work plate 1 near the middle position, the frame 41 is arranged from front to back, and the horizontal plate end of the frame 41 is located above the conveyor belt 22.

[0036] The frame 41 is fixed to the top surface of the work plate 1 near the middle, with the horizontal plate end located above the conveyor belt 22, so that the guiding mechanism 4 can accurately cover the cardboard on the conveyor belt, ensuring that the guiding force is applied in place, improving the targeting and effectiveness of the guidance, and avoiding misalignment.

[0037] Specifically, the guide mechanism 4 also includes two rotating columns 42 that are rotatably connected to the two vertical plate ends of the frame 41 respectively. The bidirectional lead screw 43 is coaxially fixed between the two rotating columns 42 and arranged from front to back. The guide motor 46 is installed on the surface of one of the vertical plate ends of the frame 41 away from the bidirectional lead screw 43. The output shaft of the guide motor 46 is coaxially connected to the rotating column 42 on the same side. The two moving rods 44 are threadedly connected to the outer circumference of the bidirectional lead screw 43 in a mutually symmetrical manner.

[0038] The bidirectional lead screw 43 is connected to the frame 41 by the rotating column 42. The guide motor 46 drives the rotating column 42, so that the bidirectional lead screw 43 rotates stably, driving the two moving rods 44 to move symmetrically in opposite directions, so that the spacing of the guide plate 47 can be adjusted accurately and smoothly to adapt to different cardboard sizes.

[0039] More specifically, the movable rod 44 is L-shaped, and the bottom surface of the horizontal plate end of the frame 41 is provided with a limiting groove arranged from front to back. The top surface of the vertical rod end of the movable rod 44 is fixed with a limiting block 45 that is slidably connected to the limiting groove on the bottom surface of the horizontal plate end of the frame 41.

[0040] The L-shaped moving rod 44, the limiting groove at the end of the horizontal plate of the frame 41, and the limiting block 45 on the moving rod 44 constrain the moving rod 44 when it slides, preventing the guide plate 47 from shaking, improving the guiding accuracy, and ensuring that the cardboard is conveyed along the preset track.

[0041] It is worth noting that the longitudinal cross-sectional shape of the upper limit groove on the bottom surface of the horizontal plate of the frame 41 is I-shaped, and the shape of the limit block 45 is I-shaped to match the shape of the upper limit groove on the bottom surface of the horizontal plate of the frame 41.

[0042] By using the I-shaped limiting groove and the matching I-shaped limiting block 45, the moving rod 44 will not detach from the frame 41 when it slides, which enhances the operational stability of the guide mechanism 4, reduces equipment failures caused by component detachment, and ensures production continuity.

[0043] It is worth noting that the guide plate 47 is fixed on the outer wall of the same side of the horizontal bar end of the same side moving rod 44 away from the same side vertical plate end of the frame 41, and the bottom surface of the guide plate 47 and the top surface of the conveyor belt 22 are on the same plane.

[0044] By fixing the guide plate 47 to a specific position at the end of the horizontal bar of the moving rod 44 and having its bottom surface flush with the top surface of the conveyor belt 22, the guide plate 47 can fully fit the side of the cardboard, ensuring the guiding effect and avoiding the obstruction of cardboard conveying due to height difference, making the transmission smoother.

[0045] It is worth emphasizing that protective plates 48 are installed on the opposite sides of the two guide plates 47. The shape of the protective plates 48 is adapted to the shape of the guide plates 47, and the thickness of the protective plates 48 is between 10mm and 15mm.

[0046] The thickness of the protective plate 48 is preferably 12mm. The protective plate 48 is installed on the opposite side by the guide plate 47, so that the edges of the cardboard are not easily worn when it is guided, thus protecting its integrity. At the same time, the protective effect and material saving are taken into account, reducing production costs.

[0047] It should be added that the transmission motor in the transmission machine body 2, the carton forming machine body 3, and the guide motor 46 are all electrically connected to the external PLC and the external power supply through wires, and the external PLC is also electrically connected to the external power supply through wires.

[0048] Finally, it should be noted that the components involved in this utility model, such as the conveyor body 2, the carton forming machine body 3, and the guide motor 46, are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection methods should refer to the working principle in this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0049] In this embodiment, during actual use, the external PLC controls the transmission motor of the transmission machine body 2 to start, and the conveyor belt 22 rotates to transport the cardboard; at the same time, the PLC controls the guide motor 46 to start according to the cardboard size, driving the bidirectional lead screw 43 to rotate, so that the two moving rods 44 drive the guide plate 47 to adjust to a suitable distance to guide the cardboard.

[0050] After being guided, the cardboard is conveyed to the main body 3 of the cardboard box forming machine. The PLC controls the main body 3 of the cardboard box forming machine to start and perform the forming operation on the cardboard. After the forming is completed, the PLC controls the transmission motor to continue running and conveys the formed cardboard box to the next process. At the same time, according to subsequent needs, the PLC can control each piece of equipment to shut down or enter the next work cycle. The entire process is coordinated by the PLC to realize automated production.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
