Description

Technical Field

[0001] This utility model relates to the field of packaging box folding technology, specifically to an automatic folding and positioning guide structure for outer packaging. Background Technology

[0002] In the packaging of collagen drinks and health foods, automatic folding boxes are key equipment for improving production efficiency, and the positioning and guiding structure is its core component. Early automatic folding boxes suffered from insufficient precision in their positioning and guiding structures, easily leading to skewed folds and jamming due to soft cardboard materials and dimensional deviations. Furthermore, their adaptability was poor, requiring significant adjustments when changing specifications, impacting production line flexibility. With the rapid development of the health food industry and increasing demands for packaging efficiency and stability, the positioning and guiding structure has been improved towards higher precision and greater adaptability to meet the needs of diverse cardboard boxes and high-speed production.

[0003] Utility model patent CN222681916U discloses an automatic box folding machine, including a support frame. Two cylinders are installed on one side of the support frame, and two folding plates are installed on the upper surface of the support frame. An adjustment structure is provided on the side of the support frame away from the cylinders. The adjustment structure includes a servo motor, which is fixedly connected to one side of the support frame. A lead screw is fixedly connected to the output end of the servo motor, and a connecting plate is threaded onto the arc surface of the lead screw. A feeding plate is fixedly connected to the upper surface of the connecting plate, and two sliding grooves are formed on the upper surface of the feeding plate. This automatic box folding machine provides the advantage of adjustable limiting plates to limit the movement of the box during folding, thereby minimizing shaking of the box during feeding, improving the stability of the feeding process, and increasing the working efficiency of the box folding machine.

[0004] Although the automatic box folding machine can limit the position of the cardboard boxes to prevent shaking during feeding and facilitate centralized transfer of boxes using storage boxes, the device still has the following problems in actual use: the position of the feeding plate is adjusted by a servo motor and lead screw, resulting in poor adaptability and versatility for different cardboard sizes. Therefore, we propose an automatic box folding positioning and guiding structure for outer packaging. Utility Model Content

[0005] In view of the shortcomings of the existing technology in terms of poor adaptability to different specifications of cardboard, it is desirable to provide an automatic folding and positioning guide structure for outer packaging.

[0006] In a first aspect, this application provides an automatic folding and positioning guide structure for outer packaging, including a base plate. Side plates and limiting plates are fixedly connected sequentially from left to right at both ends of the top surface of the base plate. An mounting plate is fixedly connected to the rear end of the top surface of the base plate. Several positioning posts are slidably connected to the top surface of the base plate near the side plates. A moving assembly is installed between the side plates and the limiting plates. The moving assembly includes horizontally arranged and parallel sliding rods and lead screws. The two ends of the sliding rods are respectively rotatably engaged with the side plates and the limiting plates, and the two ends of the lead screws are also respectively rotatably engaged with the side plates and the limiting plates. The sliding rods and lead screws slide outwards. A C-shaped movable block is fitted on the mounting plate. The bottom surface of the movable block is connected to an adsorption plate via a first cylinder. Several suction cups are fixedly connected to the bottom surface of the adsorption plate. A vertically arranged second cylinder is fixedly connected to the mounting plate via a mounting bracket. A pressing plate is fixedly connected to the end of the telescopic rod of the second cylinder. A folding base is fixedly connected to the top surface of the base plate directly below the pressing plate. A folding assembly is installed on the top surface of the folding base. The folding assembly includes two opposing first guide plates and two opposing second guide plates. Both the first and second guide plates are slidably connected to the top surface of the folding base.

[0007] According to the technical solution provided in the embodiments of this application, a sliding rod is fixedly connected to the bottom surface of the positioning post, and the bottom plate is provided with a positioning through groove that is connected to the top and bottom and perpendicular to each other. The diameter of the sliding rod is adapted to the groove width of the positioning through groove, and a positioning nut for fixing the positioning post is threaded to the bottom end of the sliding rod.

[0008] In this setting, the adjustable positioning column is achieved by sliding the sliding rod within the positioning slot, thereby improving the equipment's adaptability to packaging boxes of different sizes.

[0009] According to the technical solution provided in the embodiments of this application, a moving motor is fixedly installed on the right side of the limiting plate, and the output shaft of the moving motor passes through the limiting plate and is coaxially connected to the lead screw.

[0010] In this setup, a movable motor drives a lead screw to rotate, which in turn causes the moving block to slide along the slide bar.

[0011] According to the technical solution provided in the embodiments of this application, the second cylinder telescopic rod is located between the slide rod and the lead screw, the opening of the C-shaped moving block faces the direction of the second cylinder, and the cross-sectional dimension of the opening of the moving block is larger than the diameter of the second cylinder telescopic rod;

[0012] In this setup, the spatial layout is optimized by limiting the shape and orientation of the moving block to avoid interference with the extension rod of the second cylinder.

[0013] According to the technical solution provided in the embodiments of this application, the adsorption plate is also in the shape of a c, and the opening of the adsorption plate and the opening of the moving block are in the same direction and have the same size. A plurality of limiting telescopic rods are fixedly connected to the bottom surface of the moving block, and the bottom end of the limiting telescopic rods is fixedly connected to the top surface of the adsorption plate.

[0014] This setting enhances the stability of the adsorption process by using a limiting telescopic rod, preventing the box from shifting or falling during transport and improving the folding accuracy.

[0015] According to the technical solution provided in the embodiments of this application, a first slider is fixedly connected to the bottom surface of the first guide plate, a second slider is fixedly connected to the bottom surface of the second guide plate, and a first and a second sliding groove that are perpendicular to each other are opened on the top surface of the folding base. The width of the first sliding groove is adapted to the size of the first slider, and the width of the second sliding groove is adapted to the size of the second slider.

[0016] In this setting, the distance between the first guide plate and the second guide plate can be adjusted to accommodate the folding requirements of boxes of different sizes, thus expanding the applicability of the equipment.

[0017] According to the technical solution provided in the embodiments of this application, a first bidirectional lead screw is rotatably engaged in the first slide groove, and two first sliders are respectively threaded to two threaded sections of the first bidirectional lead screw. A second bidirectional lead screw is rotatably engaged in the second slide groove, and two second sliders are respectively threaded to two threaded sections of the second bidirectional lead screw. The first bidirectional lead screw and the second bidirectional lead screw do not contact each other.

[0018] In this setup, a bidirectional lead screw is used to achieve synchronous and symmetrical adjustment of the guide plate, ensuring the consistency of the folded edges on both sides of the box and improving the folding quality.

[0019] According to the technical solution provided in the embodiments of this application, the right end of the first bidirectional lead screw passes through the folding base and the limiting plate and is coaxially connected to a first turntable, and the front end of the second bidirectional lead screw passes through the folding base and is coaxially connected to a second turntable.

[0020] In this configuration, the first and second turntables drive the first and second bidirectional lead screws to rotate, respectively.

[0021] According to the technical solution provided in the embodiments of this application, a plurality of legs are fixedly connected to the bottom surface of the base plate, and the length of the legs is greater than the distance from the bottom end of the sliding rod to the bottom surface of the base plate;

[0022] In this setup, the support legs ensure that the sliding rod and positioning nut have sufficient operating space when adjusting the positioning column, while raising the equipment makes it easier to place the box or connect to other conveying devices, thus improving operational convenience.

[0023] In summary, this technical solution specifically discloses an automatic folding and positioning guide structure for outer packaging, which includes a first bidirectional lead screw, a second bidirectional lead screw, a first guide plate, and a second guide plate. By driving the first and second bidirectional lead screws to slide horizontally, the oppositely arranged first and second guide plates can be folded, enabling the folding of cardboard of different sizes and shapes, and exhibiting good adaptability and multifunctionality.

[0037] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0038] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0039] Please see Figures 1-6 The automatic folding and positioning guide structure for outer packaging includes a base plate 1. Side plates 11 and limiting plates 13 are fixedly connected from left to right at both ends of the top surface of the base plate 1. An mounting plate 12 is fixedly connected to the rear end of the top surface of the base plate 1. Several positioning posts 2 are slidably connected to the top surface of the base plate 1 near the side plates 11. A moving assembly 3 is installed between the side plates 11 and the limiting plates 13. The moving assembly 3 includes horizontally arranged and parallel sliding rods 32 and lead rods 33. The two ends of the sliding rods 32 are rotatably engaged with the side plates 11 and the limiting plates 13, respectively. The two ends of the lead rods 33 are also rotatably engaged with the side plates 11 and the limiting plates 13, respectively. The sliding rods 32 and the lead rods 33 are slidably sleeved with the same... A C-shaped movable block 31 has an adsorption plate 35 connected to its bottom surface via a first cylinder 34. Several suction cups 36 are fixedly connected to the bottom surface of the adsorption plate 35. A vertically arranged second cylinder 4 is fixedly connected to the mounting plate 12 via a mounting bracket 15. A pressing plate 41 is fixedly connected to the end of the telescopic rod of the second cylinder 4. A folding base 16 is fixedly connected to the top surface of the base plate 1 directly below the pressing plate 41. A folding assembly 5 is installed on the top surface of the folding base 16. The folding assembly 5 includes two opposing first guide plates 51 and two opposing second guide plates 55. Both the first guide plates 51 and the second guide plates 55 are slidably connected to the top surface of the folding base 16.

[0040] In this embodiment, as Figure 3 As shown, a sliding rod 21 is fixedly connected to the bottom surface of the positioning post 2. The bottom plate 1 has a positioning through groove 14 that is connected to the top and bottom and perpendicular to each other. The diameter of the sliding rod 21 is matched with the groove width of the positioning through groove 14. The sliding rod 21 can slide along the positioning through groove 14, thereby driving the positioning post 2 to adjust its horizontal position to fit packaging box blanks of different sizes. The bottom end of the sliding rod 21 is threaded with a positioning nut 22 for fixing the positioning post 2. After tightening, the sliding rod 21 can be fixed, thereby fixing the position of the positioning post 2.

[0041] Furthermore, such as Figure 1As shown, a moving motor 38 is fixedly installed on the right side of the limiting plate 13. The output shaft of the moving motor 38 passes through the limiting plate 13 and is coaxially connected to the lead screw 33. The moving motor 38 provides power to drive the lead screw 33 to rotate. Through the threaded engagement between the lead screw 33 and the moving block 31, the moving block 31 is driven to move horizontally along the slide bar 32, thereby realizing the automated transfer of the adsorption plate 35.

[0042] Furthermore, such as Figure 1 and Figure 4 As shown, the telescopic rod of the second cylinder 4 is located between the slide rod 32 and the lead screw 33. The opening of the C-shaped moving block 31 faces the direction of the second cylinder 4, and the cross-sectional dimension of the opening of the moving block 31 is larger than the diameter of the telescopic rod of the second cylinder 4. This prevents the moving block 31 from colliding with the telescopic rod of the second cylinder 4 when it moves horizontally, and ensures that the actions of the moving component 3 and the folding component 5 do not interfere with each other.

[0043] It is important to note that, such as Figure 4 As shown, the adsorption plate 35 is also U-shaped, and the opening of the adsorption plate 35 and the opening of the moving block 31 are in the same direction and have the same size, further avoiding interference with the telescopic rod of the second cylinder 4. Several limiting telescopic rods 37 are fixedly connected to the bottom surface of the moving block 31. The bottom end of the limiting telescopic rod 37 is fixedly connected to the top surface of the adsorption plate 35, which restricts the lifting direction of the adsorption plate 35, prevents it from tilting, and ensures that the suction cup 36 adsorbs the folded box stably.

[0044] In this embodiment, as Figure 2 and 6 As shown, a first slider 52 is fixedly connected to the bottom surface of the first guide plate 51, and a second slider 56 is fixedly connected to the bottom surface of the second guide plate 55. The top surface of the folding base 16 has a first groove 161 and a second groove 162 that are perpendicular to each other. The width of the first groove 161 is adapted to the size of the first slider 52. The first slider 52 slides along the first groove 161, driving the first guide plate 51 to move. The width of the second groove 162 is adapted to the size of the second slider 56. The second slider 56 slides along the second groove 162, driving the second guide plate 55 to move in a direction perpendicular to the first groove 161.

[0045] Furthermore, such as Figure 2 and 6As shown, a first bidirectional lead screw 53 is rotatably engaged in the first slide groove 161, and two first sliders 52 are respectively threaded to two threaded sections with opposite helical directions on the first bidirectional lead screw 53. A second bidirectional lead screw 57 is rotatably engaged in the second slide groove 162, and two second sliders 56 are respectively threaded to two threaded sections with opposite helical directions on the second bidirectional lead screw 57. The first bidirectional lead screw 53 and the second bidirectional lead screw 57 do not contact each other. When the first bidirectional lead screw 53 is rotated, the two first sliders 52 move synchronously in opposite directions, driving the first guide plate 51 to adjust the spacing synchronously; similarly, the second bidirectional lead screw 57 drives the second guide plate 55 to adjust the spacing synchronously.

[0046] Furthermore, such as Figure 6 As shown, the right end of the first bidirectional lead screw 53 passes through the folding base 16 and the limiting plate 13 and is coaxially connected to the first turntable 54. Manually rotating the first turntable 54 can drive the first bidirectional lead screw 53 to rotate, thereby adjusting the spacing of the first guide plate 51. The front end of the second bidirectional lead screw 57 passes through the folding base 16 and is coaxially connected to the second turntable 58. Rotating the second turntable 58 can drive the second bidirectional lead screw 57 to rotate, thereby adjusting the spacing of the second guide plate 55.

[0047] It is worth mentioning that, such as Figure 1 As shown, several support legs 17 are fixedly connected to the bottom surface of the base plate 1 to support the entire equipment, so that the bottom surface of the base plate 1 is off the ground. The length of the support legs 17 is greater than the distance between the bottom end of the sliding rod 21 and the bottom surface of the base plate 1, ensuring that the bottom end of the sliding rod 21 does not contact the ground and avoid affecting the adjustment of the position of the positioning column 2.

[0048] Finally, it should be noted that the components involved in this utility model, such as the first cylinder 34, the moving motor 38, and the second cylinder 4, 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 of 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] Working principle: In this embodiment, the automatic folding box positioning and guiding structure for outer packaging first adjusts the position of the positioning post 2 by sliding the sliding rod 21 within the positioning groove 14 and fixing it with the positioning nut 22 according to the size of the box to be folded. Then, the first turntable 54 and the second turntable 58 are rotated to drive the first bidirectional lead screw 53 and the second bidirectional lead screw 57 to rotate, causing the first slider 52 and the second slider 56 to move the guide plate within the corresponding groove, thereby fixing the position of the first guide plate 51 and the second guide plate 55 in the folding assembly 5, completing the positioning and guiding preparation. Next, the moving motor 3... 8 drives the lead screw 33 to rotate, causing the moving block 31, which is sleeved on the slide rod 32 and the lead screw 33, to move above the box. The extension rod of the first cylinder 34 extends, causing the suction plate 35 to descend. After the suction cup 36 adsorbs the box, the first cylinder 34 retracts. The moving motor 38 then drives the moving block 31 to move the box above the folding base 16. Finally, the extension rod of the second cylinder 4 extends, causing the pressing plate 41 to descend, causing the suction cup 36 to release the box. With the guidance of the first guide plate 51 and the second guide plate 55, the folding operation of the box is completed. After folding, the second cylinder 4 retracts and resets, waiting for the next operation.
