Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a paper box stamping and forming device, including a forming box 1. Two connecting rods 3 are fixedly connected to the middle right side of the forming box 1. The same mounting plate 4 is fixedly connected to the right side of each of the two connecting rods 3. A hydraulic rod 5 is fixedly connected to the left side of the mounting plate 4. An iron plate 6 is fixedly connected to the left side of the hydraulic rod 5. The hydraulic rod 5 pushes the iron plate 6 to move into the forming box 1. A magnetic block 7 is magnetically connected to the left side of the iron plate 6. A pressing plate 8 is fixedly connected to the left side of the magnetic block 7 for pushing the cardboard. A second magnetic block 9 is magnetically connected to the left side of the pressing plate 8. When clamping the cardboard, the second magnetic block 9 is removed, then the cardboard is placed on top, and then the second magnetic block 9 is placed back on, forming a magnetic force with the first magnetic block 7 to clamp the cardboard. The interior is provided with mounting holes 10 on all four sides. Each mounting hole 10 is slidably connected with a positioning pin 11. Each positioning pin 11 is fixedly connected with a forming plate 12. The cardboard is pushed into the interior of the forming box 1 and becomes a carton through the forming plate 12. The forming plate 12 is inserted into the interior of the mounting hole 10 through the positioning pin 11. Multiple round holes 13 are provided in the upper middle part of the right side of the forming box 1. The same mounting bracket 14 is slidably connected to the interior of each round hole 13. The mounting bracket 14 is inserted into the interior of the round hole 13 and passes through the positioning pin 11. Bolts 15 are threadedly connected to the four corners on the right side of the mounting bracket 14. The mounting bracket 14 is installed on the right side of the forming box 1 through the bolts 15. A carton release mechanism 2 is provided on the left side of the forming box 1.

[0036] Specifically, two parallel connecting rods 3 are fixedly connected to the middle right side of the forming box 1. The right ends of the two rods are connected to a rectangular mounting plate 4. A hydraulic rod 5 is fixedly installed in the center of the left side of the mounting plate 4, and its left end is fixedly connected to an iron plate 6. When the hydraulic rod 5 is activated, it can push the iron plate 6 to move horizontally into the forming box 1. A magnetic block 7 is connected to the left side of the iron plate 6 by magnetic adsorption. The left end of the magnetic block is fixedly connected to the extrusion plate 8, forming a cardboard pushing assembly that can move synchronously. A magnetic block 9 is also magnetically adsorbed on the left side of the extrusion plate 8. When clamping the cardboard, the magnetic block 9 must be removed first, the cardboard placed in the predetermined position on the left side of the extrusion plate 8, and then the magnetic block 9 is reinstalled so that it is clamped to the cardboard by magnetic force with the magnetic block 7, ensuring the stability of the cardboard position during the pushing process. Multiple mounting holes 10 are evenly distributed around the inside of the forming box 1. A positioning pin 11 is slidably connected in each set of symmetrical mounting holes 10. A forming plate 12 is fixedly connected between adjacent positioning pins 11. 2. Through the cooperation of the positioning pin 11 and the mounting hole 10, different specifications of forming cavities can be flexibly assembled. When the hydraulic rod 5 pushes the extrusion plate 8 holding the cardboard to move into the forming box 1, the cardboard will gradually contact and squeeze the forming plate 12. Under the limiting action of the forming plate 12, the folding and forming are completed, and finally a carton is formed. Multiple horizontally arranged round holes 13 are opened in the upper right side of the forming box 1. The mounting bracket 14 can be inserted into these round holes 13 at the same time and pass through the middle of the positioning pin 11. Threaded holes are provided at the four corners on its right side. By screwing in the bolt 15, the mounting bracket 14 can be fastened to the right side wall of the forming box 1, thereby forming a lateral limit on the positioning pin 11 and preventing it from shifting during the stamping process. This makes the installation and disassembly of the forming plate 12 convenient. Just loosen the bolt 15 and remove the mounting bracket 14, and the positioning pin 11 can be pulled out from the mounting hole 10. Different specifications of forming plate 12 combinations can be quickly replaced to adapt to diverse carton production needs, significantly improving production efficiency and equipment versatility.

[0037] Reference Figure 3 and Figure 5 The unloading mechanism 2 includes two connecting plates 201. The right sides of the two connecting plates 201 are fixedly connected to the left side of the forming box 1. Telescopic rods 202 are fixedly connected between adjacent connecting plates 201. Clamping plates 203 are fixedly connected between adjacent telescopic rods 202. The telescopic rods 202 push the clamping plates 203 to extend and retract inward. Multiple anti-slip tubes 204 are fixedly connected between adjacent clamping plates 203. When the carton is pushed out, the telescopic rods 202 push the clamping plates 203 to clamp the carton. The anti-slip tubes 204 increase the friction with the carton. A camera 205 is fixedly connected to the bottom rear side of the top connecting plate 201 to watch whether the clamping plates 203 are pressing against the surface of the carton. When they are pressed, the telescopic rods 202 stop, and then the hydraulic rods 5 retract.

[0038] Specifically, two parallel connecting plates 201 are fixedly connected to the left side of the forming box 1. Telescopic rods 202 are symmetrically installed between them. The telescopic ends of the telescopic rods 202 are connected to a clamping plate 203. When the telescopic rods 202 are activated, they drive the clamping plate 203 to move horizontally towards the center of the forming box 1. Multiple anti-slip tubes 204 are evenly fixed on the opposing inner surfaces of the two clamping plates 203. These tubes have fine textures to increase friction. When the carton is formed and the extrusion plate 8 is pushed out from the right side of the forming box 1, the telescopic rods 202 on the left side simultaneously push the clamping plate 203 inward, allowing it to retract through the anti-slip tubes 204 and the carton. The surface contacts form a stable clamping force. A camera 205 is fixedly installed on the bottom rear side of the top connecting plate 201, with its lens facing the contact area between the clamping plate 203 and the carton. When the clamping plate 203 begins to clamp, the camera 205 captures the image in real time and transmits it to the control system. The operator or program can observe whether the anti-slip tube 204 is evenly pressed onto the surface of the carton through the image. When it is detected that the clamping plate 203 is completely in contact with the carton and there is no deviation, the telescopic rod 202 stops moving to ensure that the clamping force is moderate and to avoid deformation of the carton due to excessive compression. The hydraulic rod 5 begins to retract, driving the extrusion plate 8 to retract to the right to the initial position.

[0039] Reference Figure 1 and Figure 2 A support plate 16 is fixedly connected to the lower front side of the molding box 1. The outer wall of the support plate 16 is chamfered for support. An operating table 17 is fixedly connected to the top of the support plate 16. Multiple buttons 18 are fixedly connected to the top of the operating table 17 for control. A display screen 19 is fixedly connected to the top front side of the molding box 1. The display screen 19 is electrically connected to the operating table 17 for displaying information. Two support rods 20 are fixedly connected to the bottom of the support plate 16. The bottom of the two support rods 20 is fixedly connected to the bottom front side of the molding box 1 to increase the support of the support plate 16.

[0040] Specifically, a support plate 16 is fixedly connected to the lower front side of the molding box 1. Its outer wall is chamfered to reduce the risk of collision with sharp corners. An operating table 17 is horizontally fixed to the top of the support plate 16. Multiple function buttons 18 are evenly distributed on its surface. Workers can accurately control the operating status of the device by pressing the buttons 18. A display screen 19 is installed on the top front side of the molding box 1. It is electrically connected to the operating table 17 through a circuit and can display the equipment operating parameters in real time, which makes it convenient for operators to monitor the equipment status and make timely adjustments. Two support rods 20 are symmetrically arranged at the bottom of the support plate 16. One end of the rod is fixed to the bottom surface of the support plate 16, and the other end extends to the bottom front side of the molding box 1 and is fixedly connected to it, forming a triangular support structure, which effectively enhances the stability of the support plate 16.

[0041] Reference Figure 1 , Figure 3 and Figure 5Support columns 21 are fixedly connected to the four corners of the bottom of the molding box 1. Anti-slip sleeves 22 are fixedly connected to the bottom of the multiple support columns 21 to prevent the device from moving when it is started. Washers 23 are fixedly connected to the middle of the outer wall of multiple bolts 15. The multiple washers 23 are all designed with rounded edges to prevent the bolts 15 from being tightened. A lamp holder 24 is fixedly connected to the front bottom of the top connecting plate 201. A lighting lamp 25 is rotatably connected to the bottom of the lamp holder 24 to increase the brightness of the clamping. The two connecting plates 201 are fixedly connected to the left side of the molding box 1 at equal intervals. The two telescopic rods 202 are both designed with symmetry.

[0042] Specifically, support columns 21 are vertically fixed at the four corners of the bottom of the molding box 1, and anti-slip sleeves 22 are fitted at their bottom ends. The anti-slip sleeves 22 are made of rubber with a textured surface to increase friction with the ground, effectively suppressing displacement caused by vibration during device startup and ensuring equipment stability. Washers 23 are fitted onto the middle of the outer walls of multiple bolts 15 of the mounting bracket 14. The edges of the washers 23 are rounded to prevent scratching the operator's hands during tightening. By increasing the contact area, the pressure on the bolts 15 is distributed, preventing the bolts 15 from being over-tightened. The bottom of the top connecting plate 201... A lamp holder 24 is fixed to the front, and a lighting lamp 25 is rotatably connected to its bottom end via a pivot. The operator can flexibly adjust the illumination angle of the lighting lamp 25 according to the lighting requirements of the clamping station to ensure sufficient brightness in the contact area between the clamping plate 203 and the carton, making it easy to observe the clamping status of the anti-slip tube 204 and the surface condition of the carton. Two connecting plates 201 are fixed to the left side of the forming box 1 in an equidistant and symmetrical manner. The matching telescopic rod 202 also adopts a symmetrical design, so that the clamping plate 203 is subjected to uniform force during the extension and retraction process, ensuring a balanced clamping force on the carton and avoiding the carton from tilting or being damaged due to force on one side.

[0043] Working principle: First, remove magnetic block 2 9, place the cardboard on the left side of the extrusion plate 8, and then use magnetic force to clamp the cardboard between magnetic block 2 9 and magnetic block 1 7. Then, the hydraulic rod 5 is activated, pushing the iron plate 6 and the extrusion plate 8 to the left, pushing the cardboard into the forming box 1. During the movement, the cardboard contacts and is squeezed by the forming plate 12 fixed by the positioning pin 11 and the mounting hole 10. Under the limiting action of the forming plate 12, it is gradually folded into a carton. When the cardboard is fully formed, the hydraulic rod 5 retracts and resets. If the carton size needs to be changed, loosen the bolt 15, remove the mounting bracket 14, and pull out the positioning pin 11. The original forming plate 12 can be disassembled and the new specification component can be replaced. The positioning pin 11 is fixed again by the mounting bracket 14 and the bolt 15 to complete the mold switching. This allows for quick replacement of the forming plate 12 according to the shape and size of the carton.

[0044] Furthermore, after the carton is folded and formed inside the forming box 1, the hydraulic rod 5 pushes the extrusion plate 8 to push the carton out from the right side to the left of the forming box 1. The left telescopic rod 202 is activated, driving the clamping plate 203 to move horizontally towards the center. The anti-slip tube 204 on the inner side of the clamping plate 203 contacts the surface of the carton through fine texture, forming a stable clamping force to fix the position of the carton. The camera 205 at the bottom of the top connecting plate 201 captures the contact image between the clamping plate 203 and the carton in real time and transmits the image to the control system. When it is detected that the anti-slip tube 204 is uniformly pressing the surface of the carton without deviation, the control system commands the telescopic rod 202 to stop moving to ensure that the clamping force is appropriate. After confirming that the carton is fixed, the hydraulic rod 5 begins to retract, driving the extrusion plate 8 to return to the initial position to the right, thereby realizing the effective demolding of the carton.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
