Description

Technical Field

[0001] This utility model relates to the field of laser marking technology, and in particular to a rapid laser marking device for toy packaging boxes. Background Technology

[0002] In the toy production and distribution process, the marking and coding of packaging boxes is a key process for product traceability, anti-counterfeiting, and information transmission. Laser marking is widely used for marking information such as production date, batch number, and traceability code on toy packaging boxes due to its advantages such as high clarity, strong durability, and no consumable pollution. With the rapid development of the toy industry, the requirements for marking efficiency and adaptability of production lines are constantly increasing. In particular, it is necessary to achieve rapid positioning and accurate marking for packaging boxes of different sizes in order to meet the flexible production needs of multiple varieties and small batches.

[0003] Existing laser marking on toy packaging boxes mostly uses fixed or semi-automatic positioning equipment. Fixed equipment transports the packaging box through a preset track and uses side baffles to achieve rough positioning. The laser printhead is fixed above to perform marking. It is suitable for mass production of a single size. Semi-automatic equipment requires manual adjustment of the spacing of the positioning components to adapt to packaging boxes of different widths. The laser action is triggered by a sensor during marking.

[0004] However, existing laser marking equipment lacks positioning accuracy during use. Fixed baffles cannot be flexibly adjusted according to the width of the packaging box, and the marking position is easily skewed due to conveying deviation. At the same time, the manual distance adjustment method of semi-automatic equipment is time-consuming and labor-intensive, and frequent machine stops are required when switching between multiple product specifications, which affects the rhythm of the production line and thus affects production efficiency. Utility Model Content

[0005] In view of the problems that existing laser marking equipment has insufficient positioning accuracy, fixed baffles cannot be flexibly adjusted according to the width of the packaging box, and the marking position is easily skewed due to conveying deviation, and the manual distance adjustment method of semi-automatic equipment is time-consuming and laborious, and frequent machine stops are required when switching between multiple product specifications, which affects the rhythm of the production line and thus affects production efficiency, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to quickly adjust the distance between the two positioning constraint plates by driving the reverse thread structure with a rotating motor, without manual intervention, flexibly adapting to packaging boxes of different widths, reducing downtime during specification changes, ensuring production line continuity, and the auxiliary connecting rod cooperating with the movable constraint groove to effectively counteract the torque generated by the thread transmission, prevent the constraint folding plate from bending, ensure positioning stability, and avoid coding skew caused by conveying offset, thereby improving production efficiency and coding quality.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a rapid laser marking device for toy packaging boxes, including a packaging box conveyor seat and two limiting horizontal plates on one side of the packaging box conveyor seat, each limiting horizontal plate having a pipe constraint block on one side, and each pipe constraint block having a guide constraint block on one side;

[0008] It also includes a positioning assembly, which includes two constraint folding plates installed between two pipe constraint blocks, each constraint folding plate having a movable sleeve on one side and a threaded sleeve on one side.

[0009] It also includes a rotating assembly, which includes a motor fixing block installed on one side of the limiting horizontal plate, a rotating motor on one side of the motor fixing block, and a rotating connecting rod on one side of the motor fixing block. One end of the rotating motor passes through the motor fixing block and is connected to the rotating connecting rod.

[0010] As a preferred embodiment of the rapid laser marking device for toy packaging boxes of this utility model, the limiting horizontal plate is provided with two fixed constraint blocks on one side, and a fixed constraint rod is fixedly provided on the inner side of the two fixed constraint blocks, and each movable sleeve is sleeved on the fixed constraint rod.

[0011] As a preferred embodiment of the rapid laser marking device for toy packaging boxes of this utility model, the rotating connecting rod is suspended after passing through two pipe constraint blocks at one end, and two external threads are opened on the rotating connecting rod, with a limiting connecting block provided between the two external threads.

[0012] As a preferred embodiment of the rapid laser marking device for toy packaging boxes of this utility model, each threaded sleeve is fitted onto the rotating connecting rod through a corresponding external thread, and an auxiliary connecting plate is provided on one side of each threaded sleeve.

[0013] As a preferred embodiment of the rapid laser marking device for toy packaging boxes of this utility model, the auxiliary connecting plate has two movable constraint slots, each movable constraint slot has an auxiliary connecting rod inside, and each auxiliary connecting rod has its two ends inserted into the inner side of the corresponding guide constraint block.

[0014] As a preferred embodiment of the rapid laser marking device for toy packaging boxes of this utility model, the inner side of the packaging box conveyor seat is provided with a transmission belt, and each packaging box conveyor seat is provided with a positioning constraint plate on one side, with one side of each positioning constraint plate being in contact with the transmission belt.

[0015] As a preferred embodiment of the rapid laser marking device for toy packaging boxes of this utility model, the device includes: a laser constraint box on one side of the two limiting horizontal plates, multiple fixed support rods on one side of the packaging box conveyor seat, and a fixed base on one side of each fixed support rod.

[0016] The beneficial effects of this utility model are:

[0017] By rotating the motor to drive the reverse thread structure, the distance between the two positioning constraint plates can be quickly adjusted without manual intervention. This allows for flexible adaptation to packaging boxes of different widths, reducing downtime during specification changes and ensuring production line continuity.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] Reference Figure 1-3This is the first embodiment of the present invention, which provides a rapid laser marking device for toy packaging boxes, including a packaging box conveyor 1 and two limiting horizontal plates 2 on one side of the packaging box conveyor 1. Each limiting horizontal plate 2 is provided with a pipe constraint block 3 on one side and a guide constraint block 4 on one side. The positioning component includes two constraint folding plates 14 installed between the two pipe constraint blocks 3. Each constraint folding plate 14 is provided with a movable sleeve 18 on one side and a threaded sleeve 13 on one side. Two fixed constraint blocks 7 are provided on one side of the limiting horizontal plate 2. Fixed constraint rods 8 are fixedly provided inside the two fixed constraint blocks 7. Each movable sleeve 18 is sleeved on the fixed constraint rod 8.

[0028] The rotating connecting rod 9 is suspended after passing through two pipe constraint blocks 3 at one end. Two external threads 10 are opened on the rotating connecting rod 9, and a limiting connecting block 11 is provided between the two external threads 10. Each threaded sleeve 13 is sleeved on the rotating connecting rod 9 through the corresponding external thread 10. An auxiliary connecting plate 16 is provided on one side of each threaded sleeve 13.

[0029] Example 2

[0030] Reference Figure 2-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the rotating assembly includes a motor fixing block 5 installed on one side of the limiting horizontal plate 2. A rotating motor 12 is provided on one side of the motor fixing block 5, and a rotating connecting rod 9 is provided on one side of the motor fixing block 5. One end of the rotating motor 12 passes through the motor fixing block 5 and is connected to the rotating connecting rod 9. Two movable constraint slots 17 are opened on the auxiliary connecting plate 16. An auxiliary connecting rod 22 is provided inside each movable constraint slot 17. Both ends of each auxiliary connecting rod 22 are respectively inserted into the inner side of the corresponding guide constraint block 4.

[0031] The inner side of the packaging box conveyor seat 1 is provided with a transmission belt 6. Each packaging box conveyor seat 1 has a positioning constraint plate 15 on one side. Each positioning constraint plate 15 is in contact with the transmission belt 6 on one side. Two limit cross plates 2 are provided with laser constraint boxes 21 on one side. Multiple fixed support rods 19 are provided on one side of the packaging box conveyor seat 1. Each fixed support rod 19 is provided with a fixed base 20 on one side.

[0032] When in use, the rotating motor 12 is started, and its output shaft drives the rotating connecting rod 9 to rotate. The two external threads 10 on the rotating connecting rod 9 are reverse threads, which mesh with the threaded sleeves 13 on both sides respectively. Therefore, when rotating, the two threaded sleeves 13 move in opposite linear motion along the external threads 10. When the threaded sleeves 13 move, they drive the connected constraint folding plate 14 to move synchronously. The movable sleeve 18 on one side of the constraint folding plate 14 slides along the fixed constraint rod 8. The fixed constraint rod 8 is fixed on the limiting horizontal plate 2 by the fixed constraint block 7, which provides guidance for the constraint folding plate 14, ensuring its smooth movement and avoiding deviation.

[0033] The other end of the constraint folding plate 14 is connected to the positioning constraint plate 15. Therefore, the positioning constraint plate 15 changes its spacing as the constraint folding plate 14 moves. When the threaded sleeves 13 move away from each other, the spacing of the positioning constraint plates 15 increases to fit a wider packaging box. When the threaded sleeves 13 move closer to each other, the spacing decreases to fit a narrower packaging box, until it matches the width of the packaging box to be printed. When the threaded sleeves 13 rotate with the rotating connecting rod 9, they will generate torque around the rotation axis, which can easily cause the constraint folding plate 14 to bend. Therefore, the auxiliary connecting plate 16 is connected to the auxiliary connecting rod 22 through the movable constraint groove 17. The two ends of the auxiliary connecting rod 22 are inserted into the guide constraint block 4 to form a transverse support structure.

[0034] When the threaded sleeve 13 is subjected to torque, the auxiliary connecting rod 22 transmits the opposite support force through the movable constraint groove 17, which counteracts the bending force of the torque on the constraint folding plate 14, ensuring that the constraint folding plate 14 always maintains a stable unfolded state and avoids affecting the positioning accuracy due to deformation. After the spacing adjustment is completed, the transmission belt 6 on the inner side of the packaging box conveyor seat 1 starts to transport the toy packaging box to the coding area. The positioning constraint plate 15 fits against both sides of the packaging box and restricts its left and right offset during the transmission process, ensuring that the central axis of the packaging box is aligned with the laser coding path.

[0035] When the packaging box passes under the laser constraint box 21, the laser device inside the laser constraint box 21 is activated to spray preset information on the surface of the packaging box. After the coding is completed, the transmission belt 6 transports the packaging box to the next process. The whole process is continuous and efficient.

[0036] The remaining structure is the same as that in Example 1.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
