Description

Technical Field

[0001] This utility model relates to the field of box gluing and folding machine technology, and in particular to a semi-automatic box gluing and folding machine. Background Technology

[0002] In the packaging and printing industry, the application of gluing and folding boxes is the final process in packaging box processing. It involves folding and gluing printed and die-cut cardboard into shape. Machine gluing replaces manual gluing, reducing labor costs and improving efficiency. The gluing and folding box machine is divided into a paper feeding section, a pre-folding section, a bottom hook section, a forming section, and a box pressing section. The working principle of the automatic gluing machine is as follows: after the power is turned on, the entire conveyor belt starts to move. The die-cut semi-finished paper boxes are placed in the paper feeding position of the gluing machine. The conveyor belt automatically feeds the single box sheet into the middle section belt according to the paper feed check set by the paper head frame. (If the semi-finished paper box has undergone surface treatment such as lamination or varnishing, glue can be applied to the inner edge of the paper box by glue gun after entering the middle section.) The conveyor belt transports the paper box to the rear gluing section for pressure packaging.

[0003] However, this type of box gluing and folding machine occupies a large space, making it inconvenient for small-scale packaging and transportation sites. Therefore, we seek to design an adjustable semi-automatic box gluing and folding machine suitable for various square packaging boxes, while also allowing for manual assistance, to achieve a miniaturized design. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a semi-automatic gluing and folding box machine.

[0005] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: a semi-automatic gluing and folding box machine, including: a workbench, a frame, a transverse inner side baffle assembly and a middle pressure plate assembly disposed on the frame, and a transverse outer side push assembly and a forward outer side push assembly disposed on the workbench. A work plate is provided on the top of the workbench, and a rectangular clearance groove is formed on the outer periphery of the work plate. The bottom plate of the die-cut and pre-folded cardboard is placed on the work plate, and glue is applied to the adhesive part of the side plate of the cardboard. The frame is vertically mounted on one side of the workbench. The transverse inner baffle assembly and the middle pressure plate assembly are located above the work plate. The middle pressure plate assembly is used to press the bottom plate of the cardboard onto the work plate. There are two transverse inner baffle assemblies, which are symmetrically arranged on the transverse sides above the work plate. The transverse inner baffle assembly is provided with a plurality of first inner baffles, which are vertically arranged on the inner side of the transverse side plate of the cardboard. Two lateral outer push-up components are provided, symmetrically arranged on both sides below the working board; each lateral outer push-up component includes a lateral push-up plate and a first push-up drive member; the first push-up drive member is used to push the lateral push-up plate upward and cause the two lateral side plates of the cardboard to flip upward and abut against the first inner baffle. Two positive outer push-up components are provided, symmetrically arranged on both sides below the working board; the positive outer push-up components include a positive push-up roller and a second push-up drive member; the second push-up drive member is used to push the positive push-up roller upward, and cause the two positive side plates of the cardboard to flip upward and abut against the adhesive part of the side plates on both sides of the lateral side.

[0006] Optionally, the frame is provided with a first transverse screw drive and a first transverse guide rail; the two transverse inner baffle assemblies are slidably disposed on the first transverse guide rail; the first transverse screw drive is provided with two sections of threads with opposite directions of rotation, which are threadedly connected to the two transverse inner baffle assemblies respectively; the first transverse screw drive can make the two transverse inner baffle assemblies move synchronously in the same or opposite directions.

[0007] Optionally, the worktable is provided with a second transverse screw drive and a second transverse guide rail; the two transverse outer push components are slidably disposed on the second transverse guide rail; the second transverse screw drive is provided with two sections of threads with opposite directions of rotation, which are threadedly connected to the two transverse outer push components respectively; the second transverse screw drive can make the two transverse outer push components move synchronously in the same direction or in opposite directions.

[0008] Optionally, the frame is further provided with a longitudinal inner baffle; the longitudinal inner baffle is vertically positioned inside the side plate of the cardboard in the longitudinal direction.

[0009] Optionally, the workbench is further provided with a lateral limiting plate assembly on the outside of the clearance ring groove; the lateral limiting plate is used to engage the side of the cardboard to limit the placement position of the cardboard.

[0010] The beneficial effects of this utility model are: 1. Compact structure, significantly reducing footprint: Through optimized design, the layout integrates key execution components on a workbench, eliminating the cumbersome conveyor belt structure of traditional gluing and folding boxes, thus achieving miniaturization of the equipment. This makes the equipment ideal for small-scale production sites with limited space, small packaging companies, or laboratories, solving the pain point of traditional equipment being difficult to deploy due to its large size.

[0011] 2. Flexible adjustment and strong versatility: The horizontal inner baffle assembly, the horizontal outer push assembly, and the forward outer push assembly are all designed for the horizontal and forward side panels of the cardboard box. Through a symmetrical layout, the equipment can be easily adjusted to meet the folding requirements of various square packaging boxes of different sizes, which significantly improves the versatility and applicability of the equipment and reduces the equipment investment cost caused by product replacement.

A work plate 11 is provided on the top of the workbench 10, and a rectangular clearance groove 12 is provided on the outer periphery of the work plate 11. The bottom plate of the die-cut and pre-folded cardboard is placed on the work plate 11, and glue is applied to the glued part of the side plate of the cardboard.

[0022] The beneficial effects of this utility model are: 1. Compact structure, significantly reducing footprint: Through optimized design, the layout integrates key execution components on a 10-workbench, eliminating the cumbersome conveyor belt structure of traditional gluing and folding box machines, thus achieving miniaturization of the equipment. This makes the equipment ideal for small-scale production sites with limited space, small packaging companies, or laboratories, solving the pain point of traditional equipment being difficult to deploy due to its large size.

[0023] 2. Flexible adjustment and strong versatility: The transverse inner baffle assembly 30, the transverse outer push assembly 50 and the forward outer push assembly 60 are all designed for the transverse and forward side panels of the paper box. Through the symmetrical layout, the equipment can be easily adjusted to adapt to the folding requirements of various square packaging boxes of different sizes, which significantly improves the versatility and applicability of the equipment and reduces the equipment investment cost caused by product replacement.

[0024] 3. Semi-automated operation, balancing efficiency and cost: This equipment automates the upward folding and pressing of the transverse and forward side panels of the cardboard box, ensuring accuracy and consistency in the forming process and effectively improving production efficiency. Simultaneously, the design cleverly allows for manual completion of steps such as gluing and material feeding, creating a semi-automated human-machine collaborative model. This not only significantly reduces reliance on complex fully automated systems, simplifies the structure, and lowers manufacturing costs, but also makes the equipment more flexible in operation, making it particularly suitable for small-batch, multi-variety production.

[0025] 4. Low energy consumption and maintenance costs: Due to the simplified structure, a large number of drive motors and long-distance conveyor belt systems are eliminated. The power consumption and daily maintenance requirements of this equipment are significantly reduced compared to fully automatic gluing and folding box machines, further reducing the long-term operating costs for users.

[0026] In this embodiment, the frame 20 is equipped with a first transverse screw drive 21 and a first transverse guide rail 22; two transverse inner baffle assemblies 30 are slidably disposed on the first transverse guide rail 22; the first transverse screw drive 21 has two sections of threads with opposite directions of rotation, which are threadedly connected to the two transverse inner baffle assemblies 30 respectively; the first transverse screw drive 21 can make the two transverse inner baffle assemblies 30 move synchronously in the same or opposite directions. Operators only need to drive one screw to quickly and accurately adjust the distance between the two baffle assemblies to accommodate cartons of different widths. This design ensures the efficiency and synchronicity of the adjustment process, completely avoiding the center offset problem caused by asynchronous adjustment of the two baffles, ensuring that the cartons are always in the correct processing position, thereby guaranteeing the final product's forming quality and consistency, and greatly reducing the labor intensity of operators.

[0027] Furthermore, the workbench 10 is equipped with a second transverse screw drive 13 and a second transverse guide rail 14; two transverse outer push-up components 50 are slidably mounted on the second transverse guide rail 14; the second transverse screw drive 13 has two sections of threads with opposite directions of rotation, which are threadedly connected to the two transverse outer push-up components 50 respectively; the second transverse screw drive 13 can make the two transverse outer push-up components 50 move synchronously in the same or opposite directions. Through the configuration of the second transverse screw drive 13 and the second transverse guide rail 14, synchronous and symmetrical adjustment of the two push-up components is achieved. Its core effect is to ensure that the points of application of the two push-up forces used for folding the transverse side panels are always symmetrical with the center of the carton width. In this way, when pushing and folding, the side panels on both sides of the carton can flip upwards simultaneously and smoothly, effectively preventing quality problems such as cardboard twisting, uneven folding, or inaccurate bonding that may be caused by unilateral force application, further improving the stability of the equipment and the yield rate.

[0028] In this embodiment, the frame 20 is also provided with a longitudinal inner baffle 32; the longitudinal inner baffle 32 is vertically positioned inside the longitudinal side panel of the cardboard. By adding the longitudinal inner baffle 32, the technical effect is to provide a reliable internal support reference for the front side panel of the carton. When the front outer push assembly 60 pushes the front side panel to flip up, the baffle can effectively block the panel from the inside, ensuring that its folding angle is accurately perpendicular to the bottom plate (usually 90 degrees), and achieving precise and misaligned pressing with the glued part of the transverse side panel, thereby ensuring the squareness and sturdiness of the overall structure of the carton and improving the yield rate of the glued box.

[0029] In this embodiment, the workbench 10 is further provided with a lateral limiting plate assembly 70 on the outer side of the avoidance ring groove 12; the lateral limiting plate is used to engage the side of the cardboard to restrict the placement position of the cardboard. The operator only needs to press the die-cut cardboard base plate against the limiting plate to easily ensure that each cardboard is placed in the correct initial position on the workbench 11, eliminating the need for repeated fine-tuning and alignment steps, greatly improving work efficiency, and fundamentally reducing processing waste caused by manual placement deviations. It is particularly suitable for production scenarios that require frequent changes in box types.

[0030] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
