Description
Technical Field
[0001] This invention relates to the field of folding boxes, and more specifically, to a folding device and method for toy boxes. Background Technology
[0002] Folding boxes are an indispensable and crucial step in the toy manufacturing and packaging process. After production, toys need to be sealed in folding boxes to prevent damage from collisions and wear during storage and transportation, ensuring the toys' appearance and performance remain intact. Furthermore, neat folding box packaging enhances the overall aesthetics of the product, making it easier for retailers to display and sell, while also providing consumers with a clean and convenient storage solution. Therefore, efficient and precise folding box operations are an essential step in the toy industry.
[0003] In existing technology, the folding of toy boxes mainly relies on manual labor. The specific process is as follows: First, the worker takes a single toy box from the stack of cardboard, lays it flat on the worktable, and manually folds the second side of the cardboard upwards to a vertical position, ensuring the side fits snugly against the main body of the box. Then, the worker folds the first side along a pre-set crease, so that the two sides are symmetrically distributed on both sides of the box. Next, the worker pinches the bottom edge of the toy box with their fingers and folds it upwards to a semi-folded state, at which point the bottom edge is at a certain angle to the main body of the box. Then, the worker uses a glue bottle or brush to evenly apply glue to the inside of the semi-folded bottom edge, controlling the amount of glue used to avoid excessive overflow or insufficient glue affecting the bonding effect. Finally, the worker presses the connection between the bottom edge and the first and second sides with their palm, holding the pressure for several seconds until the glue has initially cured, then releases their palm, completing the folding of the entire toy box. During this process, the worker must operate each toy box independently, from unfolding the cardboard to final bonding and fixing; every step relies on manual labor.
[0004] Existing manual box folding methods have several drawbacks. First, in the side folding stage, manual folding relies entirely on the operator's experience and feel, making it difficult to ensure that the first and second sides of each toy box are folded at the same angle. This often results in problems such as side tilting and incomplete folding, leading to low box forming precision and inconsistent appearance. Second, during the bottom half-folding process, there is no standardized guide or positioning device. The degree of bottom half-folding depends entirely on the operator's subjective judgment, resulting in differences in the degree of bottom folding between different toy boxes, which in turn affects the accuracy of subsequent glue spraying and bonding. Third, when applying glue manually, it is difficult to precisely control the amount and application location of the glue. Too much glue will cause overflow and contaminate the surface of the toy box, while too little glue will result in weak bonding and the box may fall apart. In addition, each step of manual box folding requires individual refining, making the folding of a single toy box time-consuming and resulting in low overall production efficiency, which is difficult to meet the packaging needs of large-scale toy production. At the same time, the repetitive actions of folding, applying glue, and pressing for a long time can easily lead to hand fatigue and muscle soreness for operators, thereby reducing the stability of operation and further aggravating the fluctuation of box folding quality.
[0005] Therefore, those skilled in the art are dedicated to providing a box-folding device and method for toy boxes that can effectively solve the above-mentioned technical problems. Summary of the Invention
[0006] To achieve the above objectives, the present invention provides a box-folding device for toy boxes, comprising:
[0007] A transmission unit is used to transport the toy box.
[0008] A first side folding mechanism is disposed outside the transmission unit and is used to fold the first side of the toy box;
[0009] The second side folding assembly is located behind the first side folding mechanism and is disposed outside the transmission unit for folding the second side of the toy box.
[0010] A bottom edge half-folding mechanism is located behind the second side edge folding assembly and is disposed outside the transmission unit for folding the bottom edge of the toy box in half.
[0011] The glue spraying mechanism is located behind the bottom edge half-folding mechanism and is disposed outside the transmission unit, for spraying glue on the bottom edge after half-folding.
[0012] The bonding mechanism, located behind the glue spraying mechanism and disposed outside the transmission unit, is used to bond the bottom edge after glue spraying to the first side edge and the second side edge.
[0013] Furthermore, the transmission unit includes a transmission frame, on which transmission rollers are provided. The transmission rollers are driven by a transmission motor, which is mounted on a transmission box. The transmission box is mounted on the transmission frame. Each of the transmission rollers is connected by a transmission chain, on which a plurality of toy box positioning components are provided. A toy box positioning area is formed between two adjacent toy box positioning components.
[0014] Furthermore, the first side folding mechanism includes a positioning seat connected to the transmission frame. A rotating shaft is rotatably mounted on the positioning seat. The lower end of the rotating shaft is connected to the output end of the power unit. A connector is provided at the upper end of the rotating shaft. The connector is connected to the positioning adjustment hole on the positioning plate through a positioning screw. A folding part is provided on the inner side of the positioning plate. The inner side of the folding part has an inclined surface. The rotating shaft drives the folding part to swing, thereby folding the first side.
[0015] Furthermore, the folding mechanism also includes a protective box, with the upper half of the rotating shaft rotatably extending out of the protective box;
[0016] The power unit is located inside the protective box. The power unit includes a cylinder mounting base, on which a cylinder is hinged. The output end of the cylinder is hinged to a swing rod, which is sleeved on the rotating shaft. The swing rod moves back and forth through the output end of the cylinder, driving the rotating shaft to rotate in both directions, thereby causing the folding part to swing back and forth.
[0017] Furthermore, the second side folding assembly includes a second side positioning frame, the upper end of which has a side adjustment port. The side adjustment plate is detachably fixed to the second side positioning frame by screws. A side guide plate is provided on the inner side of the side adjustment plate. The front half of the side guide plate has an arc-shaped guide portion integrally formed therewith. By swinging the folding part and the arc-shaped guide portion, the first side and the second side are folded in sequence.
[0018] Furthermore, the bottom edge semi-folding mechanism includes a guide bar, the lower end of which is detachably connected to the upper end of the transmission frame. The semi-folding frame is connected to the outside of the transmission frame. An adjustable top plate is provided at the upper end of the semi-folding frame. A guide plate is provided on the inner side of the adjustable top plate. The guide bar is located between the guide plate and the semi-folding frame, forming a bottom edge semi-folding channel between the guide bar and the guide plate. The lower end of the guide plate is suspended.
[0019] Furthermore, the glue spraying mechanism includes a glue spraying machine base connected to the transmission frame, a glue spraying machine is provided on the glue spraying machine base, and a glue spraying nozzle is provided on the glue spraying machine. The glue spraying nozzle is inclined inward and glue is sprayed onto the bottom edge that is half-folded and inclined through the inclined glue spraying nozzle.
[0020] Furthermore, the bonding mechanism includes a suspended bonding push plate, which is connected to the output end of the drive unit.
[0021] Furthermore, the drive unit includes a mounting box, on which two power discs are provided. The power discs are driven by an adhesive motor located inside the mounting box. An eccentric rod is rotatably mounted on the power disc, and the upper end of the eccentric rod rotatably passes through each support lug. Each support lug is simultaneously connected to the adhesive push plate.
[0022] A folding method for a toy box: The toy box, filled with toys, is located in a positioning area. A transmission motor in a transmission unit drives a transmission roller, which in turn drives a toy box positioning component via a transmission chain, causing the toy box to be transported within the positioning area. The second side of the toy box first contacts an arc-shaped guide portion, which, in conjunction with a side guide plate, folds the second side. Then, a cylinder drives a swing arm, which in turn rotates a rotating shaft. This rotation causes the folding portion of the positioning plate to swing along an inclined surface, folding the first side. The box then continues to be conveyed forward by the transmission unit. The two sides and the first side are located outside the guide plate. After the folded bottom edge contacts the guide strip, it enters the channel, making its bottom edge half-folded. It continues to be transported through the transmission unit, so that the half-folded bottom edge moves out of the channel until it moves to below the glue nozzle. The glue sprayer sprays glue on the inside of the bottom edge. After the glue spraying is completed, it continues to move through the transmission unit. When it moves to the bonding mechanism, the bonding motor drives the power plate, which causes the eccentric rod to drive the bonding push plate to move, bonding the glued bottom edge to the first side and the second side, completing the entire toy box folding process.
[0023] The present invention has the following beneficial effects:
[0024] 1. This invention uses the arc-shaped guide part and side guide plate of the second side folding component, in conjunction with the cylinder-driven swing rod and rotating shaft of the first side folding mechanism to drive the folding part to swing, folding both sides according to a preset trajectory and angle. The positioning plate can be finely adjusted through the positioning adjustment hole to ensure that the side folding angle of all toy boxes is uniform, the box body forming accuracy is high and the appearance is neat, solving the problems of inconsistent side angles and low forming accuracy of manual folding.
[0025] 2. The bottom edge semi-folding mechanism of the present invention forms a fixed bottom edge semi-folding channel through the guide strip and the guide plate. When the toy box is transported, the bottom edge enters along the channel and is forced to form a standard semi-folding state, eliminating the difference in manual operation and solving the problem of large difference in the bottom edge semi-folding range.
[0026] 3. The glue spraying mechanism of the present invention uses an inwardly inclined glue spraying nozzle to accurately spray glue onto the inner side of the half-folded, inclined bottom edge. The amount of glue sprayed is precisely controlled by the glue spraying machine to avoid glue overflow and contamination or insufficient amount, ensuring bonding reliability and solving the problem of inaccurate control of glue amount and position when manually applying glue.
[0027] 4. This invention enables continuous automatic transport of toy boxes through the transport rollers, transport chains, and toy box positioning components of the transport unit. Combined with the sequentially arranged folding, glue spraying, and bonding mechanisms, it forms an assembly line operation, which significantly shortens the folding time of a single toy box, improves overall production efficiency, and solves the problems of low efficiency and difficulty in meeting the needs of large-scale production caused by manual folding.
[0028] 5. This invention automates the entire process of side folding, bottom half-folding, glue spraying, and bonding without human intervention, avoiding operational errors caused by human fatigue, ensuring stable box folding quality, reducing labor costs, and solving the problems of fatigue and box folding quality fluctuations caused by repetitive manual operations.

When it moves to the bonding mechanism (11), the bonding motor drives the power plate (60) so that the eccentric rod (62) drives the bonding push plate (57) to move, and the glued bottom edge (9) is bonded to the first side edge (5) and the second side edge (7) to complete the entire toy box folding process.
