Description

Technical Field

[0001] This utility model relates to the field of gift box processing technology, specifically a precision embedding device for gift box linings. Background Technology

[0002] As consumer demand for gift packaging increases, the precision and production efficiency of gift box liners, which protect gifts and enhance packaging quality, have become a key focus in the industry. Gift box liners are typically made of materials such as foam, velvet, cardboard, and EVA, and must be precisely fitted according to the size of the gift box and the shape of the gift to achieve both shock absorption and aesthetic appeal.

[0003] Traditional gift box lining embedding processes suffer from significant limitations due to their manual operation. Workers rely heavily on visual observation and manual experience, manually aligning the lining edges with the slots on the box's inner wall one by one. This process is not only time-consuming and labor-intensive, but also often requires multiple adjustments for each individual box. In mass production scenarios, this easily leads to worker fatigue, further impacting operational stability and efficiency. More importantly, manual operation is highly susceptible to subjective factors, making precision difficult to guarantee. Especially when handling flexible linings with complex curved contours, such as velvet, it's challenging to accurately control the embedding position and force by hand, frequently resulting in lining misalignment, edge lifting, or incomplete embedding in certain areas. This directly leads to insufficient fit between the lining and the gift box, visually detracting from the overall aesthetics and high-end feel of the packaging. This uncontrollable manual operation often causes fluctuations in the finished product yield when undertaking high-end gift box orders due to inconsistent lining embedding precision, sometimes requiring additional manpower for rework, severely restricting production efficiency and product quality stability.

[0004] Before embedding the liner into the gift box, the gift box itself needs to be positioned. However, manually positioning the gift box may result in inaccurate positioning, which will cause the liner to be unable to be accurately embedded into the predetermined position inside the gift box, affecting the final embedding quality and packaging effect. Therefore, a precise embedding device for gift box liners is needed. Utility Model Content

[0005] The purpose of this utility model is to provide a precise embedding device for gift box linings. By setting baffles and limiting components, the gift box itself is positioned to avoid deviation when the lining is embedded in the gift box, thereby solving the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A precision embedding device for gift box liners includes a conveying module that moves the gift box, an embedding component for embedding the liner into the gift box is installed on the upper part of the conveying module, a baffle that limits one side of the gift box is installed on the upper surface of the conveying module, and a limiting component that cooperates with the baffle to position the gift box is installed on one side of the conveying module.

[0008] The limiting component includes an electric push rod installed on one side of the conveying module. The output end of the electric push rod is located on the upper part of the conveying module and a fixed block is installed thereon. Two sets of limiting blocks for limiting the gift box are slidably installed on the side wall of the fixed block. The opposite sides of the two sets of limiting blocks are provided with guides for the gift box to slide into the limiting area.

[0009] Preferably, the middle part of the fixing block is provided with a sliding groove for connecting the limiting block, and one side of each of the two sets of limiting blocks is equipped with a slider that slides inside the sliding groove.

[0010] Preferably, a servo motor for driving the first bidirectional screw to rotate is installed on the side wall of the fixed block. The first bidirectional screw is installed through the inside of the slide groove, and both sets of sliders are threadedly connected to the middle of the first bidirectional screw.

[0011] Preferably, the embedded component includes a fixed column installed on the other side of the conveying module, a connecting frame for fixing a cylinder is rotatably mounted on the upper part of the fixed column, and a fixing plate for fixing the inner lining of the gift box is installed through the connecting frame at the output end of the cylinder.

[0012] Preferably, a movable groove is provided in the middle of the fixed plate, a second bidirectional screw is installed inside the movable groove, and two sets of detachable clamping plates for holding the inner lining of the gift box are symmetrically installed inside the movable groove at the middle of the second bidirectional screw.

[0013] Preferably, a stepper motor for driving the active cone wheel to rotate is installed inside the fixed disk, and a driven cone wheel that meshes with the active cone wheel is installed in the middle of the second bidirectional screw.

[0014] Preferably, several sets of suction cups for adsorbing and fixing the inner lining of the gift box are symmetrically installed on the lower surface of the fixed plate on both sides of the moving groove, and the input end of the suction cup on the same side passes through the middle of the fixed plate and is connected to the same connector.

[0015] Preferably, an air pump is installed on the upper part of the connecting frame to provide suction force for the suction cup, and the output end of the air pump is connected to two sets of connectors through a hose.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] Before embedding the liner into the gift box, the operator needs to pre-adjust the spacing between the two sets of limiting blocks according to the size of the gift box, ensuring that the inner side fits tightly against the outer wall of the gift box. When the conveying module delivers the gift box to the vicinity of the limiting components, the electric push rod is activated to move the fixing block and the limiting block towards the gift box. During the movement, the edge of the gift box contacts the guide arc surface of the limiting block, automatically corrects its position under the guidance of the arc surface, and enters the predetermined area in the middle of the two sets of limiting blocks. At the same time, the other side of the gift box is tightly against the baffle. Through the coordinated cooperation of the baffle and the limiting components, the gift box is quickly and accurately positioned, effectively avoiding the deviation of manual positioning, thereby ensuring the quality of the subsequent liner embedding and the overall packaging effect.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides: a precision embedding device for gift box linings, such as... Figures 1-5As shown, the system includes a conveying module 1 that moves the gift box, an embedding component 2 for embedding the inner liner into the gift box, a baffle 3 for limiting one side of the gift box, and a positioning component 4 that works with the baffle 3 to position the gift box on one side of the conveying module 1. The conveying module 1 moves the gift box along a preset track via a conveying structure, providing continuous material transport for the inner liner embedding. The embedding component 2 is used to precisely embed the inner liner into the gift box, achieving assembly between the inner liner and the gift box. The baffle 3 is used to limit one edge of the gift box, providing a lateral positioning reference. The positioning component 4 works in conjunction with the baffle 3 to position the gift box at multiple angles, ensuring accurate positioning of the gift box when embedding the inner liner.

[0026] The limiting component 4 includes an electric push rod 41 mounted on one side of the conveying module 1. A fixed block 42 is mounted on the upper part of the conveying module 1 at the output end of the electric push rod 41. Two sets of limiting blocks 43 for limiting the gift box are slidably mounted on the side wall of the fixed block 42. Each set of limiting blocks 43 has a guide for the gift box to slide into the limiting area 44 on its opposite sides. The electric push rod 41 drives the output shaft to extend and retract via electrical power, causing the fixed block 42 to move perpendicular to the conveying direction, allowing the limiting blocks 43 to move closer to or further away from the gift box. The fixed block 42 allows the limiting blocks 43 to move along with the output end of the electric push rod 41, and the sliding groove 45 on its side wall provides a track for the sliding of the limiting blocks 43. When the limiting blocks 43 move with the electric push rod 41, they directly contact the gift box and apply a limiting force. The guide arc surface 44 on its side plays a guiding role when the gift box is positioned, guiding the gift box to quickly and safely enter the middle of the two limiting blocks 43. According to the size of the gift box, the operator adjusts the spacing of the limit blocks 43 using the servo motor 47, and then the electric push rod 41 is activated, pushing the fixing block 42 towards the gift box. When the edge of the gift box contacts the guide arc surface 44, it slides along the arc surface and is pushed towards the baffle 3 until both sides of the gift box are pressed against the baffle 3 and the limit block 43 respectively, completing the positioning.

[0027] The electric actuator 41 can be a 300mm travel type. 300mm can cover the width variations of most small and medium-sized gift boxes without making the device too bulky.

[0028] Preferably, the fixing block 42 has a groove 45 in the middle for connecting the limiting block 43, and a slider 46 that slides inside the groove 45 is installed on one side of each of the two sets of limiting blocks 43. The groove 45 is opened along the moving direction of the limiting block 43, providing a sliding channel for the slider 46 on the side of the limiting block 43, thereby restricting the moving trajectory of the limiting block 43. The slider 46 is embedded in the groove 45 and moves synchronously with the limiting block 43, ensuring that the limiting block 43 slides smoothly.

[0029] Preferably, a servo motor 47 is mounted on the side wall of the fixing block 42 to drive the first bidirectional screw 48 to rotate. The first bidirectional screw 48 is installed through the inside of the slide groove 45, and both sets of sliders 46 are threadedly connected to the middle of the first bidirectional screw 48. The servo motor 47 drives the first bidirectional screw 48 to rotate, converting the rotational motion into linear motion, so that the two sets of sliders 46 connected to the reverse threads at both ends of the first bidirectional screw 48 slide inside the slide groove 45. After the operator inputs the gift box size parameters, the servo motor 47 starts, driving the first bidirectional screw 48 to rotate. The two sets of sliders 46 move synchronously to the middle or sides within the slide groove 45, causing the limiting block 43 to adjust the spacing, preparing for subsequent positioning.

[0030] The servo motor 47 can be a motor with a holding torque of 0.3 N·m. A holding torque of 0.3 N·m is perfectly sufficient and reasonable for driving the bidirectional screw and the two relatively lightweight limit blocks that move within the slide. It can overcome the static friction between the screw drive and the slider and the slide, ensuring a secure lock-in position after adjustment.

[0031] Furthermore, the embedding component 2 includes a fixed column 21 mounted on the other side of the conveying module 1. A connecting frame 22 for fixing a cylinder 23 is rotatably mounted on the upper part of the fixed column 21. A fixing plate 24 for fixing the inner lining of the gift box is mounted through the connecting frame 22 at the output end of the cylinder 23. The fixed column 21 is used to fix the connecting frame 22 and provide it with a fulcrum for rotation. The connecting frame 22 is rotatably mounted on the upper part of the fixed column 21 and can rotate around the axis of the fixed column 21. After the fixing plate 24 fixes the outer inner lining, the gift box is rotated and the inner lining is embedded inside the gift box. The cylinder 23 is mounted on the connecting frame 22 and drives the fixing plate 24 to move up and down through the extension and retraction of the output shaft, thereby realizing the downward pressing and embedding action of the inner lining. The fixing plate 24 is mounted on the output end of the cylinder 23 and is used to clamp and fix the inner lining of the gift box. The suction cup 247 on its lower surface and the clamping plate 243 on its side together ensure that the inner lining is reliably fixed.

[0032] Cylinder 23 can be a cylinder with an output force of 200N. 200N is a moderate value, which can provide enough force to stably and reliably press the lining of common materials (such as EVA, corrugated cardboard, plastic, etc.) into the bottom of the gift box, without being too large and causing damage to the more fragile gift box or lining.

[0033] Furthermore, a movable groove 241 is provided in the middle of the fixed plate 24. A second bidirectional screw 242 is installed inside the movable groove 241. Two sets of detachable clamping plates 243, which hold the inner lining of the gift box, are symmetrically installed inside the movable groove 241 at the middle of the second bidirectional screw 242. The movable groove 241 is used to install the second bidirectional screw 242 and also provides a track for the sliding of the clamping plates 243. The reverse threads at both ends of the second bidirectional screw 242 engage with the internal threads of the clamping plates 243, allowing the two sets of clamping plates 243 to move synchronously in opposite directions by rotating the second bidirectional screw 242. The clamping plates 24 are symmetrically installed in the middle of the second bidirectional screw 242, fixing the inner lining with clamping force, and forming a multi-point fixation in conjunction with the suction cup 247.

[0034] It is worth noting that a stepper motor 244, which drives the active conical wheel 245 to rotate, is installed inside the fixed plate 24. A driven conical wheel 246, which meshes with the active conical wheel 245, is installed in the middle of the second bidirectional screw 242. The stepper motor 244 can transmit power to the second bidirectional screw 242 through the meshing of the active conical wheel 245 and the driven conical wheel 246, converting the rotational motion into the rotational motion of the screw, thereby driving the clamping plate 243 in the middle of the second bidirectional screw 242 to move. The stepper motor 244 drives the active conical wheel 245 to rotate, and the driven conical wheel 246 causes the second bidirectional screw 242 to rotate synchronously. The clamping plates 243 on the two sets of second bidirectional screws 242 move precisely within the moving groove 241, realizing the adjustment of the clamping distance and ensuring that liners of different sizes can be stably clamped.

[0035] The stepper motor 244 can be a motor with a holding torque of 0.5 N·m. The torque of 0.5 N·m is suitable for clamping the edges of common gift box lining materials (such as EVA and corrugated cardboard), providing sufficient clamping force to prevent slippage, while the motor size and power consumption are also relatively moderate.

[0036] Specifically, several sets of suction cups 247 for adsorbing and fixing the inner lining of the gift box are symmetrically installed on both sides of the lower surface of the fixed plate 24, located on both sides of the moving groove 241. The input end of the suction cup 247 on the same side passes through the middle of the fixed plate 24 and is connected to the same connector. The suction cups 247 are symmetrically distributed on both sides of the moving groove 241, and adsorb the upper surface of the inner lining through negative pressure, forming a three-dimensional fixation with the side clamping of the clamping plate 243. The connector is used to connect the suction cups 247 to the external air circuit, so that the suction cups can stably hold the inner lining, and together with the clamping of the clamping plate 243, a double fixation is achieved to prevent the inner lining from falling off during movement. At the same time, the detachable design of the clamping plate 243 allows the device to fix the inner lining of rigid materials by adsorbing and fixing it only by the suction cups 247, thereby ensuring the accuracy of the device embedding.

[0037] More specifically, an air pump 248 is installed on the upper part of the connecting frame 22 to provide suction force for the suction cup 247. The output end of the air pump 248 is connected to two sets of connectors via a hose 249. The air pump 248 is used to generate negative pressure, which provides suction force to the suction cup 247 through the hose 249 connected to the connectors and the suction cup 247, ensuring the reliable suction and fixation of the liner. When the clamping plates 243 clamp the two sides of the liner, the air pump 248 is activated, delivering negative pressure airflow to the suction cup 247 through the hose 249 and connectors, and the suction cup 247 adsorbs the upper surface of the liner. At this time, the liner is doubly fixed by side clamping and top suction. When the cylinder 23 presses down, the liner is vertically embedded into the gift box under the action of the fixing plate 24, ensuring accurate embedding and avoiding embedding deviation caused by liner displacement.

[0038] Air pump 248 can be a pump with a flow rate of 15L / min. A flow rate of 15L / min can ensure that a sufficient working vacuum is established for the suction cup in a short time to meet the production cycle requirements, and can be replenished in time in case of minor leakage.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
