Abstract
Description
Technical Field
[0001] This utility model belongs to the field of packaging, specifically relating to a fully automatic packaging and labeling production equipment for packaging boxes. Background Technology
[0002] In existing technologies, product packaging is mainly divided into two independent stages: boxing and labeling.
[0003] Specifically, cardboard box packaging typically uses two sealing methods: tape sealing and glue sealing. Tape sealing is mostly used for top and bottom sealing, while glue sealing is more commonly used for horizontal left and right sealing. For long and narrow packaging boxes, glue sealing is more commonly used. However, when it comes to application scenarios that require tape sealing and tape wrapping, the existing equipment on the market often lacks versatility, especially for large packaging machines that are longer than 1 meter. The packaging equipment on the market has the following significant shortcomings.
[0004] 1. Lack of universal equipment: Existing packaging equipment is limited to packaging specific product models. This makes it easy for the various mechanisms to interfere with each other when packaging different product models, which in turn affects the smoothness and stability of the entire packaging process.
[0005] 2. High cost and low integration: Existing equipment often requires manual intervention, and traditional packaging and sealing are usually done by separate equipment. This separate operation not only increases production costs but also reduces the overall efficiency of the production line. For companies that pursue a highly integrated production environment, such a setup obviously cannot meet their requirements. Utility Model Content

[0036] Compared with the prior art, the present invention has the following beneficial effects:
[0037] (1) The present invention provides a fully automatic packaging and labeling production equipment for packaging boxes. Through the adjustment mechanism, it can adapt and adjust to boxes of different specifications, thereby improving the equipment's versatility and adaptability. Combined with the movement of the centering mechanism and the centering effect of the correction block, it avoids interference between the positions of the various mechanisms and provides a reliable guarantee for subsequent automated operation, thereby realizing the integrated operation of automatic folding, sealing and labeling of boxes with multiple covers.
[0038] (2) The smaller guide surface design helps the corrective block enter the packaging box more smoothly, avoiding accidental push into the packaging box due to any panel drooping during the centering process, ensuring the smoothness and stability of the entire centering process. At the same time, the corrective surface achieves precise positioning of the box body by sticking the opposite sides together, avoiding the problem of not being able to seal and label being misaligned due to box body offset.
[0039] (3) The design of the tilting rod effectively guides the cover plate to fold and avoids misalignment caused by manual or mechanical impact; the use of the clamping block to press the second and fourth cover plates simultaneously ensures the flatness and sealing of the sealing surface and ensures that the product quality meets the required usage requirements.

[0053] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0054] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.
[0055] like Figures 1 to 6As shown, this utility model discloses a fully automatic packaging and labeling production equipment for packaging boxes. The packaging box includes a box body 10 and a first cover plate 11, a second cover plate 12, a third cover plate 13, and a fourth cover plate 14 located at the ends of the box body 10. Each cover plate has a folding gap with the box body 10. The equipment includes a machine base 2, a fixing mechanism 20, a moving mechanism 21, an adjusting mechanism 3, a centering mechanism 4, a first flipping mechanism 5, a second flipping mechanism 6, and a sealing mechanism 7.
[0056] Specifically, in this embodiment, both the fixing mechanism 20 and the moving mechanism 21 are mounted on the machine base 2. The moving mechanism 21 and the fixing mechanism 20 are used to support the box body 10 and push the box body 10 to move relative to the machine base 2. The adjusting mechanism 3 is connected to the fixing mechanism 20 and the moving mechanism 21. The adjusting mechanism 3 is used to adjust the distance between the moving mechanism 21 and the fixing mechanism 20 to adapt to different sizes of box bodies 10. The centering mechanism 4 is movably mounted on the machine base 2. The centering mechanism 4 includes a straightening block 40, which extends movably into the box body 10, such that the horizontal center line of the straightening block 40 is collinear with the length direction of the box body 10. The first flipping mechanism 5 and The second flipping mechanism 6 is installed on the machine base 2. The first flipping mechanism 5 is used to guide the first cover plate 11 and the third cover plate 13 to be folded in sequence relative to the box body 10. The second flipping mechanism 6 is used to guide the second cover plate 12 and the fourth cover plate 14 to be folded in sequence relative to the box body 10 and to cover the first cover plate 11 and the third cover plate 13 to achieve a seal inside the box body 10. The sealing mechanism 7 is installed on the machine base 2. The sealing mechanism 7 is used to wrap tape around the intersection of the folds of the second cover plate 12 and the fourth cover plate 14 and seal the gap between the folds before labeling. The labeling machine is installed on the machine base 2 and is used to automatically label the formed packaging boxes.
[0057] In this embodiment, the first cover plate 11, the second cover plate 12, the third cover plate 13, and the fourth cover plate 14 are rectangularly distributed at the end opening of the box body 10. Before sealing the box body 10, workers or robots can place products (such as umbrellas) into the box body 10 and send the packaging box to be sealed onto the fixed mechanism 20 and the moving mechanism 21 on the machine 2. With the coordinated action of the adjusting mechanism 3, the stable placement of the box body 10 can be ensured, and it can also drive the moving mechanism 21 to move laterally relative to the fixed mechanism 20 (i.e., move closer to or away from the fixed mechanism 20) according to the different sizes of the packaging boxes, so as to accurately match the current width of the box body 10, thereby improving the applicability and flexibility of the equipment. Similarly, in this embodiment, the correction block 40 is driven by the centering mechanism 4 and extends horizontally into the box 10, so that the horizontal center line of the correction block 40 is collinear with the length direction of the box 10, thus achieving the centering calibration function. It is worth noting that the centering mechanism 4 can also move relative to the machine platform 2 to adapt to the position adjustment of the moving mechanism 21 on the machine platform 2, avoiding interference between the two and affecting the normal sealing and labeling operation of the equipment, further improving the overall operational flexibility of the equipment. After everything is ready, as the box 10 moves along the... Figure 1 During the process of the machine 2 moving from right to left, the first flipping mechanism 5 can pre-contact the first cover plate 11 and fold it along the opening at the end of the box 10 (i.e., fold it inward along the folding gap). Simultaneously, the third cover plate 13, which is opposite to the first cover plate 11, completes the folding operation. While waiting for the box 10 to move to the side of the second flipping mechanism 6, the second flipping mechanism 6 folds the second cover plate 12 and the fourth cover plate 14, located at the upper and lower ends of the opening of the box 10, along the folding gap, and covers the folded first cover plate 11 and the third cover plate 13, forming a double-layer sealing structure for the product inside the box 10, ensuring that the product is not easily damaged. Finally, the sealing mechanism 7, according to the set program, accurately wraps the pre-cut tape around the intersection of the second cover plate 12 and the fourth cover plate 14, and after the tape covers the folding gap, it further strengthens the sealing effect, preventing leakage of contents or external contamination. Then, the labeling machine can automatically label the product, and the product can be unloaded under the operation of a robot or manual operation. It is evident that the automated process of this equipment replaces manual operation, achieving fully automated operation of "feeding - positioning - folding - sealing - labeling - discharging", saving labor costs, significantly shortening the time required to seal a single packaging box, improving the adaptability of the entire equipment to packaging boxes of different specifications, and also helping to reduce production cycle time and improve the overall efficiency of the production line.
[0058] Both the fixed mechanism 20 and the moving mechanism 21 include: a mounting plate 220, which is mounted on the machine base 2. The mounting plate 220 is equipped with a drive sprocket and a driven sprocket 221, which are connected by a chain 222; and several anti-detachment blocks 223, which are equidistantly distributed on the side wall of the chain 222. An anti-detachment cavity 224 is formed between two adjacent anti-detachment blocks 223, and the box body 10 is placed in the anti-detachment cavity 224.
[0059] like Figure 1 As shown, in this embodiment, the mounting plate 220 is vertically mounted on the machine base 2. Before conveying begins, the worker can adjust the distance between two adjacent anti-detachment blocks 223 (i.e., control the size of the anti-detachment cavity 224) according to the actual packaging box specifications to ensure better positioning of the packaging box and prevent displacement or detachment. After the packaging box is accurately placed, the drive sprocket is rotated by a stepper motor or servo motor. Driven by the chain 222, the packaging box is moved along a predetermined direction to the flipping mechanism and sealing mechanism 7 for corresponding operations. Therefore, the design of the anti-detachment cavity 224 effectively covers both sides of the box body 10, providing sufficient friction and limiting space to prevent the packaging box from slipping or shifting, ensuring the accuracy of subsequent folding and sealing actions. Alternatively, this drive structure can also be replaced by a synchronous belt drive commonly used in traditional machinery.
[0060] The adjustment mechanism 3 includes a rotating rod 30 and a moving block 31. The moving block 31 is located on one of the mounting plates 220 and is movably connected to the rotating rod 30, so that when the rotating rod 30 rotates, it can drive one of the mounting plates 220 to move relative to the machine base 2.
[0061] like Figure 1 As shown, the fixed mechanism 20 and the moving mechanism 21 in this embodiment have the same structure. The difference is that the moving mechanism 21 is designed to be movable relative to the machine base 2, so that it can be moved closer to or further away from the fixed mechanism 20 by adjusting the mechanism 3. Specifically, the rotating rod 30 in this embodiment can also be connected to the output end of the motor. When the rotating rod 30 rotates, it can drive the moving block 31 to move linearly back and forth along the axis of the rotating rod 30, thereby adjusting the displacement of the mounting plate 220 and its components on the machine base 2, and finally realizing the adjustment of the distance between the two mounting plates 220 to meet the needs of different long strip packaging boxes with lengths of 700-1700mm and a maximum cross-sectional size of 350*350mm. It should be noted that this structure is the same as the ball screw transmission structure in machinery, with high adjustment accuracy, smooth operation, low noise, and improved flexibility of production.
[0062] The machine base 2 is also equipped with a fixed slide rail 23, and an adjustment handle 24 is provided on the fixed slide rail 23. A sliding block 410 is connected to the bottom wall of the fixed base 41. When the adjustment handle 24 is rotated, it can drive the sliding block 410 to move back and forth along the length of the fixed slide rail 23.
[0063] like Figure 1 As shown, in this embodiment, the fixed slide rail 23 is perpendicular to the mounting plate 220 in the horizontal direction. After the fixed plate and its components on the moving mechanism 21 are adjusted on the machine base 2, the centering mechanism 4 is also adjusted accordingly. Specifically, the operator rotates the adjusting handle 24 according to the prompts. The handle drives the sliding block 410 to move forward or backward along the fixed slide rail 23 through a lead screw or gear transmission structure. The movement distance can be confirmed by a scale or limit switch to ensure that the correction block 40 reaches the target working position. This structure has good linearity and repeatability, supports the adaptation of packaging boxes of different widths, heights or shapes, and can quickly adjust the working position of the centering mechanism 4 according to different product models, reducing downtime for model changeover.
[0064] The centering mechanism 4 includes a fixed base 41 and a drive cylinder 42. The fixed base 41 is mounted on the machine base 2, and the drive cylinder 42 is mounted on the fixed base 41. The output end of the drive cylinder 42 is connected to the straightening block 40 to drive the straightening block 40 to move relative to the box body 10.
[0065] like Figure 1 and Figure 5 As shown, in this embodiment, the straightening block 40 can be connected to the output end of the drive cylinder 42 by screws or bolts, so as to facilitate timely disassembly and replacement when wear or damage occurs, providing great convenience for workers. After the sensor on the standby table 2 detects and confirms that the packaging box is in place, the drive cylinder 42 receives the signal and drives the straightening block 40 to extend into the box body 10. During this process, the front end of the straightening block 40 lightly touches the inner wall of the box body 10. If there is any deviation, a horizontal force can be applied. Under the continuous push of the cylinder, the packaging box is slowly adjusted to its position by the reaction force of the straightening block 40. During the straightening process, the box body 10 slides slightly in the anti-detachment cavity 224 until the center line coincides with the center line of the straightening block 40. It is precisely because of the existence of the centering mechanism 4 that the packaging box is accurately adjusted to the set position before sealing and gluing, effectively avoiding problems such as uneven folding and incomplete sealing caused by deviation, and improving the appearance quality and sealing performance of the finished product.
[0066] The correction block 40 includes a guide surface 400 and a correction surface 401 arranged in parallel. A guide slope 402 connects the guide surface 400 and the correction surface 401. The surface area of the guide surface 400 is smaller than the inner cavity of the box body 10. At least one set of opposite sides on the correction surface 401 is movably attached to the inner cavity of the box body 10.
[0067] Furthermore, such as Figure 5 As shown, during the above-mentioned correction process, the guide surface 400 at the front end of the correction block 40 first enters the cavity of the box body 10. Due to its small surface area, it can easily avoid obstacles or uneven areas that may exist in the four cover plates, which helps the correction block 40 to enter the packaging box more smoothly and prevents it from being accidentally pushed into the packaging box due to any panel drooping during the alignment process, thus ensuring the smoothness and stability of the entire alignment process. As the correcting block 40 continues to advance, the guiding inclined surface 402 gradually contacts the inner wall of the box 10. If the box 10 is offset to the left or right, the inclined surface will contact one side of the box 10 first. The inclined surface generates a horizontal component force, pushing the box 10 to move towards the center line. After the correcting block 40 is fully inserted, the correcting surface 401 is tightly attached to both sides of the inner wall of the box 10. The correcting surface 401 provides stable bidirectional support force to prevent the box 10 from shifting again. At this time, the box 10 is accurately located on the preset center line, which meets the requirements of subsequent folding, sealing and other processes, and avoids the problem of being unable to seal and label being misaligned due to the offset of the box 10.
[0068] The first folding mechanism includes: a mounting frame 50, mounted on the machine base 2; a guide wheel 51 and an inclined bracket 52, the guide wheel 51 being mounted on the mounting frame 50; the inclined bracket 52 being connected to the mounting frame 50 and set at an angle to it, and a traction wheel 53 being connected to the inclined bracket 52 for guiding the first cover plate 11 to fold relative to the box body 10; an auxiliary lever 55, movably mounted on the machine base 2, for guiding the cover plate to fold relative to the box body 10; a toggle cylinder 56 and a lever 57, the toggle cylinder 56 being mounted on the mounting frame 50, the output end of the toggle cylinder 56 being connected to a rotating block 560 that can rotate relative to the mounting frame 50, and the lever 57 being connected to the rotating block 560 to push the third cover plate 13 to fold relative to the box body 10 toward the direction of the first cover plate 11.
[0069] like Figures 1 to 2 As shown, it should be noted that the following working principles are all based on... Figure 1 The following explanation uses the four covers on the right end of the packaging box as an example. When the box 10 moves on the machine 2 (i.e., during...) Figure 2(Moving from right to left), the actuating cylinder 56 drives the rotating block 560 to rotate, causing the lever 57 to move away from the box body 10, ensuring that the first cover plate 11 will not continue to bend outwards from the box body 10 due to the lever 57. As the first cover plate 11 is guided into the predetermined direction under the slight pressure applied by the guide wheel 51, during the continued movement of the box body 10, the traction wheel 53 is set at a specific angle through the inclined bracket 52, gradually pushing the first cover plate 11 to fold inwards from the box body 10 along the folding gap. Preferably, the rotation direction of the traction wheel 53 is opposite to the movement direction of the box body 10, thereby driving the first cover plate 11 to fold smoothly and avoiding jamming or tearing. At this time, the actuating cylinder 56 drives the rotating block 560 to rotate relative to the mounting bracket 50, thereby driving the lever 57 to rotate around the rotating block 560 as the rotation center, pushing the third cover plate 13 to fold towards the first cover plate 11 along the folding gap. Therefore, with the coordinated operation of the two sets of guiding structures, this structure ensures that the folding sequence of the cover plates at different positions is reasonable and the actions are continuous, reducing errors caused by manual intervention, and also providing a good foundation for subsequent tape sealing, thereby improving the overall sealing performance.
[0070] It should be noted that before the lever 57 applies force to the third cover plate 13, the auxiliary lever 55 can pre-fold the third cover plate 13 towards the first cover plate 11 along the folding gap, thereby reducing the folding force directly applied by the lever 57 to the third cover plate 13 and achieving a flexible folding operation. Preferably, the machine base 2 is equipped with a rotary cylinder or rotary motor, and the output shaft of this component is provided with a mounting block 54. The auxiliary lever 55 can be detachably connected to the mounting block 54 by screws, providing convenience for subsequent disassembly and assembly. In addition, the auxiliary lever 55 has an oblong hole 550, which can be used to effectively adjust the relative position between the auxiliary lever 55 and the mounting block 54, ensuring that the auxiliary lever 55 has sufficient distance to accurately and smoothly complete the pre-folding operation of the third cover plate 13.
[0071] The second flanging mechanism includes: an inclined rod 60, which is mounted on the mounting frame 50 and is used to guide the second cover plate 12 and the fourth cover plate 14 to fold relative to the box body 10; and a sealing assembly, which is mounted on the machine base 2 and has a pressing block 64 movably mounted on it. The pressing block 64 is used to drive the fourth cover plate 14 and the second cover plate 12 to simultaneously press against the opening end of the inner cavity of the box body 10.
[0072] like Figures 1 to 4As shown, the above structure is mainly for the folding operation of the first cover plate 11 and the third cover plate 13 at the left and right ends of the box body 10. The second folding mechanism is for the folding operation of the second cover plate 12 and the fourth cover plate 14 (the upper and lower parts of the box body 10). Specifically, for the second cover plate 12 above the box body 10, in this embodiment, a tilting rod 60 guides the second cover plate 12, which moves synchronously with the box body 10, to fold into the box body 10. No additional power source is required. The folding action is automatically triggered as long as the packaging box moves forward, reducing the number of cylinders or motors and reducing energy consumption and maintenance costs. Preferably, the tilt degree of the tilting rod 60 can be adaptively adjusted during installation according to actual needs to ensure that the folded second cover plate 12 can be accurately attached to the first cover plate 11 and the third cover plate 13. As for the fourth cover plate 14, in this embodiment, the sealing component drives the movement of the pressing block 64. With the pressing action of the pressing block 64, the fourth cover plate 14 is tightly combined with the box body 10, which significantly improves the product's appearance quality and dustproof and waterproof performance.
[0073] The sealing assembly also includes: a driving component, which is mounted on the machine base 2, and the output end of the driving component is connected to a driving bevel gear 61; a moving plate 62 and a driven bevel gear 63, wherein the moving plate 62 is movably mounted on the machine base 2, and a connecting post 65 is provided between the pressing block 64 and the moving plate 62; the driven bevel gear 63 meshes with the driving bevel gear 61, and when the driven bevel gear 63 rotates, it can drive the moving plate 62 to move linearly back and forth.
[0074] like Figure 3 and Figure 4 As shown, in this embodiment, an inclined rod 60 (i.e., near the bottom of the opening of the box 10) can also be provided on the machine base 2 near the fourth cover plate 14, thereby effectively guiding the fourth cover plate 14 to perform a pre-folding operation. As the driving component drives the active bevel gear 61 to rotate, since the bottom wall of the moving plate 62 is equipped with a rack (not shown in the figure) along the moving direction of the abutment block 64, and the output shaft of the driven bevel gear 63 is equipped with a gear that meshes with the rack, the rotational motion of the driven bevel gear 63 is converted into the linear motion of the moving plate 62 and its components. In this embodiment, the moving plate 62 is preferably connected to the machine base 2 by a meshing guide rail 66 and a guide block 67. This further guides the moving plate 62 to drive the pressing block 64 to press the fourth cover plate 14 against the opening of the box body 10 (i.e., against the already folded first cover plate 11 and third cover plate 13, and flush with the second cover plate 12). This structure enables unmanned operation, avoids deformation of the cover plate due to excessive pressure, or poor adhesion due to insufficient pressure, and significantly improves production efficiency and product consistency. It should be noted that the driving component in this embodiment can be replaced by other driving devices such as stepper motors or servo motors.
[0075] The sealing mechanism 7 includes: a fixed frame 70, mounted on the machine base 2, with a drive motor 71 installed on the fixed frame 70; a drive wheel 72 and a driven wheel 73, mounted on the fixed frame 70, with the drive wheel 72 connected to the output end of the drive motor 71, and a belt 74 connecting the drive wheel 72 and the driven wheel 73; a glue tray 75, the outer wall of which is movably pressed against the driven wheel 73 so that when the driven wheel 73 drives the glue tray 75 to rotate, the adhesive tape on the inner wall of the glue tray 75 is wrapped around the fold gap; and a labeling machine, mounted on the machine base 2, which is used to automatically label the formed packaging boxes.
[0076] like Figure 1 and Figure 6 As shown, after all four lids of the packaging box have been folded, the sealing mechanism 7 is in standby mode. It should be noted that the tape tray 75 is pre-loaded with a roll of adhesive tape, one end of which is extended and ready for winding. As the drive motor 71 drives the drive wheel 72 to rotate at high speed, the drive wheel 72 transmits power to the driven wheel 73 via the belt 74. The driven wheel 73 rotates, and its outer edge rubs against the outer wall of the tape tray 75, thus causing the tape tray 75 to rotate. As the tape tray 75 rotates, the internal roll of adhesive tape is pulled out, one end of which is guided by a guide roller for precise sealing. The tape is wrapped around the packaging box (i.e., the intersection of the second cover plate 12 and the fourth cover plate 14, using a one-line sealing technique). Immediately afterwards, the tape seals the folded gap between the cover plate and the box body 10, further reinforcing the cover plate closure structure and preventing leakage of contents or external contamination. After wrapping, the cutting device (not shown in the figure) cuts the tape to complete the sealing action. Automatic labeling is then performed using the labeling machine (not shown in the figure) at the end of the machine 2. The structure and working principle of the labeling machine can be referred to existing technology, and will not be described in detail here.
