[0006] The embodiments of this application adopt the following technical solutions: A folding device for gift box production includes a folding table with two sets of support frames on its exterior. Two side plates are located above the folding table, each with a conveying assembly on one side. A folding positioning plate is fixedly connected to one side of each of the two side plates. A threaded adjusting plate is provided on the bottom surface of the folding table, and two support plates are fixedly connected to the outer surface of the threaded adjusting plate. Cylinders are fixedly mounted on the upper surfaces of the two sets of support plates, and folding top plates are fixedly mounted on the extension ends of the two cylinders. Both folding top plates are located on one side of the folding positioning plate. A sensing plate is fixedly connected to the upper surfaces of the two side plates, and the bottom surface of the sensing plate is fixed... A sensor assembly is installed. A cardboard storage frame is fixedly installed on the upper surface of the folding table. A cardboard feeding component is fixedly installed on the bottom surface of the folding table. The cardboard feeding component includes two support plates fixedly installed on the bottom surface of the folding table. Bearings are fixedly embedded on the side of the two support plates that are close to each other. A silicone feeding roller is fixedly connected to the inner ring of the two bearings. A variable frequency motor is fixedly installed on one side of the support plate. The output end of the variable frequency motor is fixedly installed to one end of the silicone feeding roller. A feeding hole is opened on the bottom surface of the folding table. The top end of the silicone feeding roller is located inside the feeding hole. A cardboard conveying hole is opened on one side of the cardboard storage frame.

[0007] Preferably, both conveying components include a servo motor fixedly mounted on one side of the side plate, a drive roller fixedly mounted on the output end of each of the two servo motors, a conveyor belt drivingly connected to the outer surface of each of the two drive rollers, two bearing rings fixedly embedded on one side of each of the two side plates, a rotating roller provided on one side of each of the two side plates, the inner rings of the two sets of bearing rings being fixedly connected to the outer surface of one end of each of the two drive rollers and the outer surface of one end of each of the two rotating rollers, respectively, a bearing ring being fixedly embedded on the bottom surface of the folding table, and the outer surface of the top end of the transmission screw being fixedly connected to the inner ring of the bearing ring.

[0008] Preferably, two fixing plates are fixedly installed on the bottom surface of the folding table. A forward and reverse motor is fixedly connected to one side of the two fixing plates that are close to each other. A transmission screw is fixedly installed at the output end of the forward and reverse motor. The outer surface of the transmission screw is fixedly connected to the bottom surface of the threaded adjustment plate. Two sliding holes are opened on the bottom surface of the threaded adjustment plate. A sliding rod is slidably connected to the inner wall of each of the two sliding holes. The top ends of the two sliding rods are fixedly connected to the bottom surface of the folding table.

[0009] Preferably, the bottom surface of the threaded adjusting plate has two sliding openings, and the bottom surfaces of the two folded top plates are fixedly connected to two sliding plates, with the outer surfaces of the two sliding plates slidably connected to the inner walls of the two sliding openings respectively.

[0010] Preferably, two limiting baffles are fixedly installed on the outer surface of the folding table, and both limiting baffles are located on one side of the folding positioning plate.

[0011] The above-described technical solutions adopted in the embodiments of this application can achieve the following beneficial effects: 1. This gift box production folding device uses cardboard pre-stacked in a storage frame, eliminating the need for frequent manual refilling. A variable frequency motor drives a silicone feeding roller to push the cardboard, ensuring stable pushing force and ensuring the bottom cardboard is fed to the left. After the bottom cardboard is fed, the upper cardboard automatically falls to fill the gap. This cyclical pushing action achieves uninterrupted feeding, avoiding the interruption problems of traditional feeding methods. A servo motor drives the drive roller and rotating roller in conjunction, driving the conveyor belt to automatically transport the cardboard above the folding table. Additionally, a sensor assembly on the bottom of the sensing plate detects the cardboard position, triggering the folding action upon reaching the correct position. During folding, a cylinder pushes the folding top plate upwards, and the folding positioning plate provides limiting guidance, folding the sides of the gift box cardboard. After folding, the conveyor belt directly delivers the cardboard out without additional ejection components, immediately entering the next processing cycle. This solves the problem of delayed output in traditional devices and improves folding efficiency.

[0012] 2. The folding device for gift box production uses a forward and reverse motor to drive the transmission screw to rotate within the bearing ring. This drives the threaded adjustment plate to rise and fall smoothly along the slide rod, allowing the cylinders and conveying components on the support plate to adapt to different cardboard thicknesses. This achieves the effect of adjusting the distance between the conveying components and the folding table, replacing the fixed edge pressing structure of traditional devices. This results in a wider range of applicability, meeting the folding requirements of gift boxes of different specifications and improving the versatility and practicality of the device.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] Example 1 As attached Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7The illustrated folding device for gift box production includes a folding table 1. Two sets of support frames 2 are provided on the outside of the folding table 1. Two side plates 3 are located above the folding table 1. A conveying assembly 4 is provided on one side of each side plate 3. A folding positioning plate 20 is fixedly connected to one side of each side plate 3. A threaded adjusting plate 9 is provided on the bottom surface of the folding table 1. Two support plates 10 are fixedly connected to the outer surface of the threaded adjusting plate 9. Cylinders 14 are fixedly installed on the upper surface of each set of support plates 10. Folding top plates 15 are fixedly installed at the extension and retraction ends of each of the two cylinders 14. Both folding top plates 15 are located on one side of the folding positioning plate 20. A sensing plate 18 is fixedly connected to the upper surface of both side plates 3. A sensor assembly 19 is fixedly installed on the bottom surface of the sensing plate 18. 9. A diffuse reflection photoelectric sensor is used. A cardboard storage frame 22 is fixedly installed on the upper surface of the folding table 1. A cardboard feeding component 21 is fixedly installed on the bottom surface of the folding table 1. The cardboard feeding component 21 includes two support plates 211 fixedly installed on the bottom surface of the folding table 1. Bearing components 214 are fixedly embedded on the side of the two support plates 211 that are close to each other. The inner rings of the two bearing components 214 are fixedly connected to a silicone feeding roller 213. A variable frequency motor 212 is fixedly installed on one side of the support plate 211. The output end of the variable frequency motor 212 is fixedly installed with one end of the silicone feeding roller 213. A feeding hole 23 is opened on the bottom surface of the folding table 1. The top end of the silicone feeding roller 213 is located inside the feeding hole 23. A cardboard conveying hole 24 is opened on one side of the cardboard storage frame 22.

[0017] As can be seen from the above description, this utility model has the following beneficial effects: the sensor assembly 19 on the bottom surface of the sensing plate 18 can detect the position of the cardboard and trigger the folding action after ensuring that it is in place. During folding, the cylinder 14 pushes the folding top plate 15 upward, and the folding positioning plate 20 is used to limit and guide the side of the gift box cardboard to be folded. After the folding is completed, the conveyor belt 43 directly sends the cardboard out without the need for an additional ejection component, and it immediately enters the next round of processing, which solves the problem of material lag in traditional devices and improves the folding efficiency.

[0018] Example 2 Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below, with reference to the specific working method described in detail: like Figure 3As shown, in a preferred embodiment, both conveying components 4 include a servo motor 41 fixedly mounted on one side of the side plate 3. Drive rollers 42 are fixedly mounted on the output ends of both servo motors 41. Conveyor belts 43 are connected to the outer surfaces of both drive rollers 42. The conveyor belts 43 are preferably made of food-grade polyurethane (PU) material, with an integrated diamond or grid pattern design on their outer surfaces to increase the friction coefficient with the gift box cardboard. Two bearing rings 45 are fixedly embedded on one side of each of the two side plates 3. A rotating roller 44 is provided on one side of each of the two side plates 3. The inner rings of the two sets of bearing rings 45 are fixedly connected to the outer surfaces of one end of each of the two drive rollers 42 and the outer surfaces of one end of each of the two rotating rollers 44, respectively. Furthermore, the servo motors 41 drive the drive rollers 42 to rotate, ensuring that the speed of the conveyor belt 43 is controllable and achieving uniform conveying of the gift box cardboard. The bearing rings 45 on the side of the side plate 3 reduce the frictional resistance when the drive rollers 42 and rotating rollers 44 rotate, ensuring smooth rotation.

[0019] like Figure 1 , Figure 2 and Figure 5 As shown, in a preferred embodiment, two fixing plates 5 are fixedly installed on the bottom surface of the folding table 1. A forward and reverse motor 6 is fixedly connected to one side of the two fixing plates 5 that are close to each other. A transmission screw 7 is fixedly installed at the output end of the forward and reverse motor 6. The outer surface of the transmission screw 7 is fixedly connected to the bottom surface of the threaded adjustment plate 9. A bearing ring 8 is fixedly embedded in the bottom surface of the folding table 1. The outer surface of the top end of the transmission screw 7 is fixedly connected to the inner ring of the bearing ring 8. Two sliding holes 11 are opened on the bottom surface of the threaded adjustment plate 9. Sliding rods 12 are slidably connected to the inner walls of the two sliding holes 11. The top ends of the two sliding rods 12 are fixedly connected to the bottom surface of the folding table 1. Two sliding openings 16 are opened on the bottom surface of the threaded adjustment plate 9. Two sliding plates 17 are fixedly connected to the bottom surfaces of the two folding top plates 15. The outer surfaces of the two sliding plates 17 are... The two sliding connections 16 are not slidably connected to the inner walls of the two sliding openings 16. Two limiting baffles 13 are fixedly installed on the outer surface of the folding table 1. Both limiting baffles 13 are located on one side of the folding positioning plate 20. Furthermore, the bearing ring 8 provides positioning support for the transmission screw 7 to prevent it from shifting during rotation and ensures the stability of the threaded adjustment plate 9's lifting and lowering adjustment. The sliding fit between the sliding hole 11 and the sliding rod 12 provides guidance for the lifting and lowering of the threaded adjustment plate 9, preventing it from shifting circumferentially with the rotation of the transmission screw 7. The sliding fit between the sliding opening 16 and the sliding plate 17 ensures that it can be smoothly lifted and lowered in the vertical direction under the drive of the cylinder 14, improving the accuracy of the folding action. The limiting baffles 13 provide lateral positioning for the gift box cardboard conveyed to the processing area to prevent the cardboard from shifting and causing inaccurate folding position.

[0020] The working process of this utility model is as follows: When using the folding device for gift box production, the cardboard for the gift box is pre-stacked in the cardboard storage frame 22. Then, the cardboard feeding component 21 on the bottom of the folding table 1 is started, and the variable frequency motor 212 drives the silicone feeding roller 213 to rotate. The silicone feeding roller 213 pushes the cardboard at the bottom of the cardboard storage frame 22 to the left. After the bottom cardboard falls, the cardboard above will continue to fall. Then, the cardboard continues to be continuously conveyed in the above manner. The cardboard enters the conveying component 4 through the cardboard conveying hole 24.

[0021] In the conveying assembly 4, the servo motor 41 drives the drive roller 42 to rotate, and the bearing ring 45 assists the drive roller 42 and the rotating roller 44 to operate smoothly. Then, the cardboard is conveyed at a constant speed through the conveyor belt 43. The texture design of the conveyor belt 43 can increase friction and prevent slippage. At the same time, the sensor assembly 19 detects the position of the cardboard in real time. Once the cardboard is in place, the subsequent folding action is triggered.

[0022] After the folding operation is started, the telescopic end of the cylinder 14 pushes the folding top plate 15 upward, which can push and fold the edge of the gift box cardboard. The folding positioning plate 20 plays a limiting and guiding role. After the folding is completed, the conveyor belt 43 continues to run to send out the processed cardboard. Then, the above method is used to continue processing the subsequent gift box cardboard. This is the working process and working principle of the device.
