Description

Technical Field

[0001] This utility model relates to the field of packaging box production technology, and in particular to a pressing and molding machine. Background Technology

[0002] In the packaging manufacturing industry, to meet the core needs of products in terms of loading, protection, and sealing, some packaging boxes adopt a split structure design of "bottom box + top cover". The processing technology of the bottom box has significant specificities: all four sides and the bottom of the box must be formed by covering and pasting adhesive tape. Furthermore, to ensure the stability of the connection after the bottom box and top cover are assembled, the adhesive tape on one side of the bottom box is specially designed to extend beyond that side, forming an extended section of adhesive tape. In the subsequent assembly process, this extended adhesive tape can precisely adhere to the corresponding side of the top cover, thereby achieving initial fixation of the bottom box and top cover, effectively ensuring the stability of the overall structure of the assembled packaging box.

[0003] However, in the current production process for this type of packaging box, the "bottom box - top cover" assembly process is generally done manually. Specifically, operators need to manually align and smoothly attach the top cover to the bottom box, while also manually extending the adhesive tape to adhere to the sides of the top cover to secure the assembly. This manual assembly method has several significant drawbacks: firstly, the efficiency of manual operation is limited, making it difficult to meet the demands of large-scale, high-efficiency production, resulting in low overall production efficiency; secondly, long-term reliance on manual operation incurs high labor costs, increasing the company's production cost burden; furthermore, the accuracy of manual operation is easily affected by the operator's experience and condition, making it difficult to guarantee the consistency of assembly quality each time, thus causing unstable assembly quality and potentially affecting the overall effect and reliability of subsequent product packaging.

[0004] To address the aforementioned problems with manual box assembly, engineers developed an automated box assembly machine capable of automatically assembling the base box and top cover. This machine aims to improve assembly efficiency, reduce labor costs, and ensure consistent assembly quality through automation. To prevent deformation of the base box due to stress and other factors during automated assembly, which could affect assembly accuracy and the structural integrity of the packaging, engineers designed a shaping mold to be placed inside the base box before assembly. This mold provides support and shape to the base box. However, this design introduces a new problem: after the base box and top cover are assembled, the shaping mold still needs to be removed from the packaging box formed by the assembly to complete the entire production process.

[0005] Currently, there is no mature automated solution for removing the shaping molds inside packaging boxes. Continuing to rely on manual removal not only leads to high labor costs and low efficiency, but also risks damaging the assembled boxes due to improper handling, affecting product quality. Therefore, in the packaging production field, it is necessary to provide at least one edge-pressing and mold-removing machine that can automatically remove the shaping molds from the packaging boxes formed by assembling the bottom and top lids. This would fill the automation gap in this stage, further improve the automated box-assembly production process, achieve full automation from box assembly to mold removal, enhance overall production efficiency and quality stability, and reduce enterprise production costs. Utility Model Content

[0006] The purpose of this utility model is to provide a pressing and mold-removing machine that can automatically remove the shaping mold inside the packaging box formed by assembling the bottom box and the top cover.

[0007] To achieve the above objectives, this utility model provides a pressing and mold-removing machine, including a frame, a product conveying mechanism, a pre-positioning mechanism, a lid-opening mechanism, and a mold-removing mechanism. The product conveying mechanism is disposed on the frame, and a pre-positioning station, a lid-opening station, and a mold-removing station are sequentially arranged on the product conveying mechanism along its conveying direction. The product conveying mechanism is used to convey packaging boxes to the pre-positioning station, the lid-opening station, and the mold-removing station in sequence. The pre-positioning mechanism is disposed on the frame and is used to pre-position the packaging box located at the pre-positioning station. The lid-opening mechanism is disposed on the frame and is used to flip and open the upper lid of the packaging box located at the lid-opening station relative to the bottom box. The mold-removing mechanism is disposed on the frame and is used to remove the shaping mold from the bottom box of the packaging box located at the mold-removing station.

[0008] Preferably, the pre-positioning mechanism includes a pre-positioning fixing member and a pre-positioning moving push module. The pre-positioning fixing member is fixed on the frame and located above the product conveying mechanism. The pre-positioning moving push module is disposed on the frame and arranged opposite to and at intervals from the pre-positioning fixing member. By moving the pre-positioning moving push module toward the pre-positioning fixing member, the packaging box at the pre-positioning station is pushed toward the pre-positioning fixing member to pre-position the packaging box. Preferably, the prepositioning moving push module includes a prepositioning linear drive component and a prepositioning pusher. The prepositioning linear drive component is disposed on the frame and located on one side of the prepositioning station. The output end of the prepositioning linear drive component is connected to the prepositioning pusher. The prepositioning linear drive component is used to drive the prepositioning pusher to move, so that the prepositioning pusher pushes the packaging box on the prepositioning station to the prepositioning fixing member. Preferably, the lid opening mechanism includes a lid opening linear movement drive assembly, a lid opening flipping drive assembly, and a lid opening suction assembly. The lid opening linear movement drive assembly is disposed on the frame, the lid opening flipping drive assembly is disposed on the lid opening linear movement drive assembly, and the lid opening suction assembly is disposed on the lid opening flipping drive assembly. The lid opening linear movement drive assembly drives the lid opening flipping drive assembly and the lid opening suction assembly to move, and the lid opening flipping drive assembly drives the lid opening suction assembly to flip, so that the lid opening suction assembly suctions the top cover of the packaging box located at the mold taking station and drives the top cover of the packaging box to flip open relative to the bottom box. Preferably, the lid-opening linear motion drive assembly includes a lid-opening linear motion drive cylinder and a lid-opening linear motion mounting component. The lid-opening linear motion drive cylinder is mounted on the frame, and its output end is connected to the lid-opening linear motion mounting component. The lid-opening linear motion drive cylinder is used to drive the lid-opening linear motion mounting component to move. The lid-opening flipping drive assembly is mounted on the lid-opening linear motion mounting component. Preferably, the lid-opening and flipping drive assembly includes a flipping drive cylinder, a belt drive assembly, and a flipping component. The flipping drive cylinder is mounted on the lid-opening linear motion mounting component. The belt drive assembly includes a drive wheel, a first rotating shaft, a driven wheel, a second rotating shaft, and a synchronous belt. The drive wheel is rotatably connected to the lid-opening linear motion mounting component via the first rotating shaft. The driven wheel is rotatably connected to the lid-opening linear motion mounting component via the second rotating shaft. The synchronous belt is wound around the drive wheel and the driven wheel. The flipping component is connected to the second rotating shaft. The lid-opening adsorption assembly is mounted on the flipping component. The output end of the flipping drive cylinder is connected to the synchronous belt. By moving the flipping drive cylinder and driving the synchronous belt, the driven wheel and the second rotating shaft rotate, thereby causing the flipping component and the lid-opening adsorption assembly to flip together. Preferably, the mold-removing mechanism includes a mold-removing X-axis moving drive assembly, a mold-removing Z-axis moving drive assembly, and a mold-removing gripper assembly. The mold-removing X-axis moving drive assembly is mounted on the frame, and the mold-removing Z-axis moving drive assembly is mounted on the mold-removing X-axis moving drive assembly. The moving drive direction of the mold-removing Z-axis moving drive assembly is perpendicular to the moving drive direction of the mold-removing X-axis moving drive assembly. The mold-removing gripper assembly is mounted on the mold-removing Z-axis moving drive assembly. The X-axis moving drive assembly drives the mold-removing Z-axis moving drive assembly and the mold-removing gripper assembly to move laterally, and the mold-removing Z-axis moving drive assembly drives the mold-removing gripper assembly to move up and down, so that the mold-removing gripper assembly removes the mold from the bottom box of the packaging box located at the mold-removing station. Preferably, the pressing and demolding machine further includes a mold return conveying mechanism, which is disposed on the frame and located on one side of the product conveying mechanism. The demolding mechanism is used to remove the shaping mold from the bottom box of the packaging box located at the demolding station and place it on the mold return conveying mechanism. The mold return conveying mechanism is used to transport the shaping mold back. Preferably, the pressing and molding machine further includes a first blocking mechanism and a lid opening and positioning mechanism. The first blocking mechanism is disposed on the frame and is used to extend to block or retract to release the packaging box located at the lid opening station. The lid opening and positioning mechanism is used to push the packaging box located at the lid opening station to position the packaging box located at the lid opening station. Preferably, the pressing and demolding machine further includes a second blocking mechanism and a demolding positioning mechanism. The second blocking mechanism is disposed on the frame and is used to extend to block or retract to release the packaging box located at the demolding station. The demolding positioning mechanism is used to push the packaging box located at the demolding station to position the packaging box located at the demolding station. Compared with existing technologies, the edge-pressing and mold-removing machine of this invention, through the automated station flow of the product conveying mechanism, can accurately transport packaging boxes sequentially to the pre-positioning station, the lid-opening station, and the mold-removing station, realizing continuous operation of "conveyance-positioning-opening-mold removal". Simultaneously, the automated actions of the lid-opening mechanism and the mold-removing mechanism require no manual intervention, enabling them to complete the opening and mold-removing operations at a stable speed. Therefore, the edge-pressing and mold-removing machine of this invention can automatically remove the mold from inside the packaging box formed by assembling the bottom box and the top cover, significantly shortening the mold-removing cycle of a single packaging box, greatly improving the efficiency of mold removal, adapting to the needs of large-scale production, and the fully automated mold-removing process eliminates the need for continuous manual operation, significantly reducing labor costs and alleviating the production burden on enterprises. Furthermore, the edge pressing and mold removal machine of this utility model, through the precise positioning of the pre-positioning mechanism, can ensure that the packaging box is in a uniform standard position before opening and mold removal, avoiding operational deviations caused by positional offsets; at the same time, the opening mechanism and the mold removal mechanism adopt mechanized motion control, which can complete the opening and mold removal according to the preset force and speed. The motion stability is far higher than that of manual operation, effectively avoiding damage to the packaging box caused by uneven force or motion deviation, ensuring the stability and safety of the mold removal process, and reducing the damage rate of the packaging box.

[0016] To explain in detail the technical content, structural features, objectives and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0017] Please see Figures 1 to 7 The pressing and molding machine 100 of this utility model includes a frame 1, a product conveying mechanism 2, a pre-positioning mechanism 3, a lid opening mechanism 4, and a molding removal mechanism 5. The product conveying mechanism 2 is mounted on the frame 1, and a pre-positioning station 21, a lid opening station 22, and a molding removal station 23 are sequentially arranged on the product conveying mechanism 2 along its conveying direction. The product conveying mechanism 2 is used to convey the packaging box 200 to the pre-positioning station 21, the lid opening station 22, and the molding removal station 23 in sequence. The pre-positioning mechanism 3 is mounted on the frame 1 and is used to pre-position the packaging box 200 located at the pre-positioning station 21. The lid opening mechanism 4 is mounted on the frame 1 and is used to flip and open the upper lid 202 of the packaging box 200 located at the lid opening station 22 relative to the bottom box 201. The molding removal mechanism 5 is mounted on the frame 1 and is used to remove the shaping mold 203 from the bottom box 201 of the packaging box 200 located at the molding removal station 23. Among them, the frame 1 serves as the installation foundation for the entire edge pressing and molding machine 100, providing a stable support platform for each mechanism and ensuring that each mechanism maintains a stable relative position during operation; the product conveying mechanism 2 realizes the orderly flow of the packaging box 200 between different workstations through continuous and precise conveying actions, providing a guarantee for the smooth operation of subsequent pre-positioning, opening, and molding processes, and avoiding the impact on overall production efficiency due to conveying interruption or positional deviation.

[0018] Please see Figures 1 to 3The prepositioning mechanism 3 includes a prepositioning fixing member 31 and a prepositioning moving push module 32. The prepositioning fixing member 31 is fixed on the frame 1 and located above the product conveying mechanism 2. The prepositioning moving push module 32 is disposed on the frame 1 and arranged opposite to and at intervals from the prepositioning fixing member 31. By moving the prepositioning moving push module 32 toward the prepositioning fixing member 31, the packaging box 200 on the prepositioning station 21 is pushed to the prepositioning fixing member 31 to preposition the packaging box 200. The pre-positioning fixing component 31 is fixedly installed and serves as a reference surface for the pre-positioning of the packaging box 200, ensuring that each packaging box 200 entering the pre-positioning station 21 can be positioned with a uniform reference. The relative arrangement of the pre-positioning moving push module 32 and the pre-positioning fixing component 31 can apply a stable pushing force from one side of the packaging box 200, making the packaging box 200 fit tightly with the pre-positioning fixing component 31. This eliminates possible positional deviations of the packaging box 200 during transportation, laying the foundation for the subsequent precise adsorption of the top cover 202 by the opening mechanism 4 and the precise gripping of the shaping mold 203 by the mold-removing mechanism 5, and avoiding operational errors caused by inaccurate positioning. Furthermore, the product conveying mechanism 2 can transport the packaging box 200 to two different positions in the pre-positioning station 21, allowing the pre-positioning mechanism 3 to perform two pre-positioning operations on the same packaging box 200, fully ensuring the accuracy of the packaging box 200's positioning.

[0019] Please see Figure 3 The prepositioning moving push module 32 includes a prepositioning linear drive component 321 and a prepositioning pusher 322. The prepositioning linear drive component 321 is mounted on the frame 1 and is located on one side of the prepositioning station 21. The output end of the prepositioning linear drive component 321 is connected to the prepositioning pusher 322. The prepositioning linear drive component 321 is used to drive the prepositioning pusher 322 to move, so that the prepositioning pusher 322 pushes the packaging box 200 on the prepositioning station 21 to the prepositioning fixing member 31. The pre-positioning linear drive assembly 321 can use mature linear drive components such as cylinders and motor screw modules, which can provide stable and adjustable driving force, ensuring that the moving speed and pushing force of the pre-positioning pusher 322 are controllable, avoiding deformation of the packaging box 200 due to excessive driving force, or inaccurate positioning due to insufficient driving force; the pre-positioning pusher 322 directly contacts the packaging box 200, and its contact surface can be designed to fit the shape of the packaging box 200 (such as flat, curved, etc.), increasing the contact area with the packaging box 200, reducing local pressure, further protecting the packaging box 200 from damage during the pre-positioning process, and improving the stability of the push positioning.

[0020] Please see Figures 2 to 4 , Figure 6 as well as Figure 7The lid opening mechanism 4 includes a lid opening linear movement drive assembly 41, a lid opening flipping drive assembly 42, and a lid opening suction assembly 43. The lid opening linear movement drive assembly 41 is mounted on the frame 1, the lid opening flipping drive assembly 42 is mounted on the lid opening linear movement drive assembly 41, and the lid opening suction assembly 43 is mounted on the lid opening flipping drive assembly 42. The lid opening linear movement drive assembly 41 drives the lid opening flipping drive assembly 42 and the lid opening suction assembly 43 to move, and the lid opening flipping drive assembly 42 drives the lid opening suction assembly 43 to flip, so that the lid opening suction assembly 43 suctions the upper cover 202 of the packaging box 200 located on the mold taking station 23 and drives the upper cover 202 of the packaging box 200 to flip open relative to the bottom box 201. The linear motion drive component 41 can drive the lid opening and flipping drive component 42 and the lid opening and suction component 43 to move linearly in space, thereby adjusting the relative position of the lid opening and suction component 43 and the top cover 202 of the packaging box 200, ensuring that the lid opening and suction component 43 can accurately fit the surface of the top cover 202; the lid opening and flipping drive component 42 is responsible for providing the flipping power, so that the lid opening and suction component 43, which is adsorbed on the top cover 202, can drive the top cover 202 to flip around a specific axis, so as to achieve stable opening of the top cover 202; the lid opening and suction component 43 usually adopts a structure such as a vacuum suction cup, and fixes the top cover 202 by negative pressure adsorption. Compared with mechanical clamping, it can effectively avoid scratches or indentations on the surface of the top cover 202, protect the appearance integrity of the packaging box 200, and the adsorption force can be adjusted according to the material and weight of the top cover 202 to ensure that the adsorption is firm and the top cover 202 is not easily damaged.

[0021] Please see Figure 4 The lid-opening linear motion drive assembly 41 includes a lid-opening linear motion drive cylinder 411 and a lid-opening linear motion mounting component 412. The lid-opening linear motion drive cylinder 411 is mounted on the frame 1, and the output end of the lid-opening linear motion drive cylinder 411 is connected to the lid-opening linear motion mounting component 412. The lid-opening linear motion drive cylinder 411 is used to drive the lid-opening linear motion mounting component 412 to move. The lid-opening flipping drive assembly 42 is mounted on the lid-opening linear motion mounting component 412. The lid-opening linear motion drive cylinder 411 has the advantages of fast response speed, stable operation, and low cost. It can quickly drive the lid-opening linear motion mounting component 412 to complete reciprocating movement, adapting to the high-speed operation requirements of the production line. As the mounting carrier of the lid-opening flip drive assembly 42, the lid-opening linear motion mounting component 412 must have sufficient strength and rigidity in its structural design to avoid shaking or deformation during movement, ensuring the stability of the lid-opening flip drive assembly 42 and the lid-opening adsorption assembly 43 mounted on it, thereby ensuring the accuracy of the lid-opening action. At the same time, multiple mounting holes can be reserved on the lid-opening linear motion mounting component 412 to facilitate the adjustment of the installation position of the lid-opening flip drive assembly 42 according to the size of different packaging boxes 200, improving the versatility of the equipment.

[0022] Please see Figure 4 The lid-opening and tilting drive assembly 42 includes a tilting drive cylinder 421, a belt drive assembly 422, and a tilting component 423. The tilting drive cylinder 421 is mounted on the lid-opening linear motion mounting component 412. The belt drive assembly 422 includes a drive wheel 422a, a first rotating shaft 422b, a driven wheel 422c, a second rotating shaft 422d, and a synchronous belt 422e. The drive wheel 422a is rotatably connected to the lid-opening linear motion mounting component 412 via the first rotating shaft 422b, and the driven wheel 422c is rotatably connected to the lid-opening linear motion mounting component 422e via the second rotating shaft 422d. On the linear moving mounting component 412, a synchronous belt 422e is wound around the driving wheel 422a and the driven wheel 422c. The flipping component 423 is connected to the second rotating shaft 422d. The opening adsorption assembly 43 is disposed on the flipping component 423. The output end of the flipping drive cylinder 421 is connected to the synchronous belt 422e. By moving the flipping drive cylinder 421 and driving the synchronous belt 422e to move, the driven wheel 422c and the second rotating shaft 422d are driven to rotate, thereby driving the flipping component 423 and the opening adsorption assembly 43 to flip together. The flipping drive cylinder 421 transmits power by pushing the synchronous belt 422e. Compared with direct drive shaft, belt drive has the function of buffering and shock absorption, which can avoid excessive impact force when the flipping action starts or stops, and protect the top cover 202 and various mechanical components. The high transmission precision of the drive wheel 422a, driven wheel 422c and synchronous belt 422e can ensure that the flipping angle of the flipping component 423 is precise and controllable, so that the top cover 202 opens to the preset angle, providing sufficient space for the subsequent mold taking mechanism 5 to extend into the bottom box 201 to grab the shaping mold 203. The rigid connection between the flipping component 423 and the second rotating shaft 422d can ensure that the rotation of the second rotating shaft 422d can be synchronously transmitted to the flipping component 423, driving the opening adsorption component 43 to flip stably, avoiding flipping jamming or angle deviation.

[0023] Please see Figure 2 , Figure 5 and Figure 7The mold-removing mechanism 5 includes a mold-removing X-axis moving drive assembly 51, a mold-removing Z-axis moving drive assembly 52, and a mold-removing gripper assembly 53. The mold-removing X-axis moving drive assembly 51 is mounted on the frame 1, and the mold-removing Z-axis moving drive assembly 52 is mounted on the mold-removing X-axis moving drive assembly 51. The moving drive direction of the mold-removing Z-axis moving drive assembly 52 is perpendicular to the moving drive direction of the mold-removing X-axis moving drive assembly 51. The mold-removing gripper assembly 53 is mounted on the mold-removing Z-axis moving drive assembly 52. ​​The mold-removing X-axis moving drive assembly 51 drives the mold-removing Z-axis moving drive assembly 52 and the mold-removing gripper assembly 53 to move laterally, and the mold-removing Z-axis moving drive assembly 52 drives the mold-removing gripper assembly 53 to move up and down, so that the mold-removing gripper assembly 53 removes the mold 203 from the bottom box 201 of the packaging box 200 located at the mold-removing station 23. The vertical arrangement of the X-axis and Z-axis moving drive components 51 and 52 enables the mold-taking gripper assembly 53 to move in both horizontal and vertical directions, thus covering the position range of the mold 203 within the base box 201 and ensuring that the mold-taking gripper assembly 53 can accurately reach the gripping position of the mold 203. The mold-taking gripper assembly 53 typically uses pneumatic or electric grippers, and the shape and size of the grippers can be customized according to the shape of the mold 203 to ensure a firm grip on the mold 203. At the same time, the gripping force of the grippers is adjustable to avoid deformation of the mold 203 due to excessive gripping force or detachment of the mold 203 during movement due to insufficient gripping force. Through the coordinated drive of the X-axis and Z-axis moving drive components 51 and 52, the mold-taking mechanism 5 can realize the complete action of removing the mold 203 from the base box 201 and moving it out of the packaging box 200, providing conditions for subsequent mold return or storage.

[0024] Please see Figure 1 and Figure 2The pressing and mold-removing machine 100 also includes a mold return conveying mechanism 6. The mold return conveying mechanism 6 is set on the frame 1 and located on one side of the product conveying mechanism 2. The mold removal mechanism 5 is used to take out the shaping mold 203 in the bottom box 201 of the packaging box 200 located at the mold removal station 23 and place it on the mold return conveying mechanism 6. The mold return conveying mechanism 6 is used to convey the shaping mold 203 back. The mold return conveyor mechanism 6 enables the recycling of the mold 203. After the mold taking mechanism 5 removes the mold 203 from the packaging box 200, it is placed directly on the mold return conveyor mechanism 6. The mold return conveyor mechanism 6 can transport the mold 203 back to the mold feeding station of the automatic box assembly machine. There is no need for manual transfer of the mold 203, which further reduces manual intervention and lowers labor costs. At the same time, it avoids mold damage or loss caused by manual transfer. In addition, the mold return conveyor mechanism 6 can adopt a belt conveyor, chain conveyor, or other structure. Its conveying speed can be matched with the mold taking speed of the mold taking mechanism 5 and the feeding speed of the automatic box assembly machine, ensuring that the mold 203 can be supplied in a timely manner and ensuring the continuous operation of the production line.

[0025] Please see Figure 3 The edge pressing and molding machine 100 also includes a first blocking mechanism 7 and a lid opening and positioning mechanism 71. The first blocking mechanism 7 is mounted on the frame 1. The first blocking mechanism 7 is used to extend to block or retract to release the packaging box 200 located at the lid opening station 22. The lid opening and positioning mechanism 71 is used to push the packaging box 200 located at the lid opening station 22 to position the packaging box 200 located at the lid opening station 22. The first blocking mechanism 7 extends when the packaging box 200 is conveyed to the opening station 22, blocking the packaging box 200 from moving further and ensuring that the packaging box 200 is accurately positioned at the preset position of the opening station 22, providing a stable operating object for the opening action of the opening mechanism 4. After the opening action is completed, the first blocking mechanism 7 retracts, releasing the packaging box 200 so that it can continue to be conveyed to the mold removal station 23. After the packaging box 200 is blocked by the first blocking mechanism 7, the opening positioning mechanism 71 pushes the packaging box 200 from the side to further correct the position of the packaging box 200, ensuring the positional accuracy of the packaging box 200 at the opening station 22. This avoids the failure of the opening adsorption component 43 to accurately adsorb the top cover 202 due to slight deviations in the packaging box 200 during the conveying process, thus ensuring the success rate of the opening action. The coordinated work of the first blocking mechanism 7 and the opening positioning mechanism 71 forms a dual positioning guarantee for the packaging box 200 at the opening station 22, improving the stability and accuracy of the opening operation.

[0026] Please see Figure 3The pressing and mold-removing machine 100 also includes a second blocking mechanism 8 and a mold-removing positioning mechanism 81. The second blocking mechanism 8 is mounted on the frame 1. The second blocking mechanism 8 is used to extend to block or retract to release the packaging box 200 located at the mold-removing station 23. The mold-removing positioning mechanism 81 is used to push the packaging box 200 located at the mold-removing station 23 to position the packaging box 200 located at the mold-removing station 23. The second blocking mechanism 8 functions similarly to the first blocking mechanism 7. It extends when the packaging box 200 is conveyed to the mold-taking station 23, stopping the packaging box 200 at the designated position of the mold-taking station 23. This ensures that the mold-taking mechanism 5 can accurately locate the mold 203 inside the bottom box 201. The mold-taking positioning mechanism 81 further adjusts the position of the packaging box 200 by pushing after the packaging box 200 has stopped, eliminating any possible positional deviations that may occur during the process of conveying the packaging box 200 from the opening station 22 to the mold-taking station 23. This ensures that the mold 203 inside the bottom box 201 is within the optimal gripping range of the mold-taking gripper assembly 53. The cooperation between the second blocking mechanism 8 and the mold-taking positioning mechanism 81 provides a higher precision positioning reference for the mold-taking mechanism 5, reduces deviations when the mold-taking gripper assembly 53 grips the mold 203, improves the success rate of mold taking, and avoids collisions between the mold-taking gripper assembly 53 and the bottom box 201 due to inaccurate positioning, which could damage the packaging box 200 or the equipment.

[0027] Combination Figures 1 to 7 The working principle of the pressing and demolding machine 100 of this utility model is as follows: First, the assembled packaging box 200, containing the shaping mold 203, is conveyed to the product conveying mechanism 2. The product conveying mechanism 2 starts and conveys the packaging boxes 200 sequentially along the conveying direction. When the packaging box 200 reaches the pre-positioning station 21, the pre-positioning linear drive component 321 of the pre-positioning moving push module 32 drives the pre-positioning push component 322 to move towards the pre-positioning fixing component 31, pushing the packaging box 200 to fit against the pre-positioning fixing component 31, completing the pre-positioning and eliminating the initial position deviation of the packaging box 200. After the pre-positioning is completed, the product conveying mechanism 2 continues to convey the packaging box 200 to the opening station 22. At this time, the first stop mechanism 7 extends to block the packaging box 200. 0. Simultaneously, the opening and positioning mechanism 71 pushes the packaging box 200, completing the precise positioning of the opening station 22. Subsequently, the opening mechanism 4 starts, and the opening linear movement drive cylinder 411 drives the opening linear movement mounting part 412 to move. The rotating drive cylinder pushes the synchronous belt 422e, which drives the driving wheel 422a and driven wheel 422c of the belt drive assembly 422 to rotate. This causes the flipping part 423, together with the opening adsorption assembly 43 and the upper cover 202, to flip together, bringing the opening adsorption assembly 43 closer to the upper cover 202 of the packaging box 200. The opening adsorption assembly 43 adsorbs the upper cover 202 through negative pressure. Then, the flipping drive cylinder 421 pushes the synchronous belt 422e to move in the opposite direction, driving the belt drive assembly... The driving wheel 422a and driven wheel 422c of component 422 rotate in opposite directions, thereby causing the flipping component 423, together with the opening suction assembly 43 and the upper cover 202, to flip in the opposite direction, thus opening the upper cover 202 to a preset angle; after the upper cover 202 is opened, the first baffle mechanism 7 retracts, the product conveying mechanism 2 conveys the packaging box 200 to the mold-taking station 23, the second baffle mechanism 8 extends to block the packaging box 200, and the mold-taking positioning mechanism 81 pushes the packaging box 200 to complete the positioning of the mold-taking station 23; then, the mold-taking mechanism 5 starts, the mold-taking X-axis moving drive assembly 51 drives the mold-taking Z-axis moving drive assembly 52 and the mold-taking gripper assembly 53 to move laterally above the shaping mold 203, and the mold-taking Z-axis moving drive assembly 51 drives the mold-taking Z-axis moving drive assembly 52 and the mold-taking gripper assembly 53 to move laterally above the shaping mold 203. The moving component 52 drives the mold-removing gripper assembly 53 to descend, and the mold-removing gripper assembly 53 closes to grasp the shaping mold 203. Then, the mold-removing Z-axis moving drive component 52 drives the mold-removing gripper assembly 53 to rise, and the mold-removing X-axis moving drive component 51 drives the mold-removing gripper assembly 53 to move laterally above the mold return conveying mechanism 6. The mold-removing gripper assembly 53 releases, and the shaping mold 203 is placed on the mold return conveying mechanism 6. The mold return conveying mechanism 6 transports the shaping mold 203 back to the upstream station for recycling. Finally, the second material blocking mechanism 8 retracts, and the product conveying mechanism 2 transports the packaging box 200 from the shaping mold 203 to the next production stage, thus completing one complete edge pressing and mold removal operation.

[0028] In summary, the edge-pressing and mold-removing machine 100 of this utility model, through the automated station flow of the product conveying mechanism 2, can sequentially and accurately convey the packaging box 200 to the pre-positioning station 21, the opening station 22, and the mold-removing station 23, realizing continuous operation of "conveyance-positioning-opening-mold removal". At the same time, the automated actions of the opening mechanism 4 and the mold-removing mechanism 5 do not require manual intervention and can complete the opening and mold-removing operations at a stable speed. Therefore, the edge-pressing and mold-removing machine 100 of this utility model can automatically remove the shaping mold 203 inside the packaging box 200 formed by assembling the bottom box 201 and the top cover 202, greatly shortening the mold-removing cycle of a single packaging box 200, significantly improving the removal efficiency of the shaping mold 203, adapting to the needs of large-scale production, and the fully automated mold-removing process does not require continuous manual operation, significantly reducing labor costs and reducing the production burden on enterprises. Secondly, the edge-pressing and mold-removing machine 100 of this invention, through the precise positioning of the pre-positioning mechanism 3, ensures that the packaging box 200 is in a uniform standard position before opening and mold removal, avoiding operational deviations caused by positional shifts. Simultaneously, the opening mechanism 4 and the mold-removing mechanism 5 employ mechanized motion control, enabling them to complete opening and mold removal according to preset force and speed. The stability of the motion is far superior to manual operation, effectively preventing damage to the packaging box 200 caused by uneven force or motion deviations, ensuring the stability and safety of the mold-removing process, and reducing the damage rate of the packaging box 200. Furthermore, the edge-pressing and mold-removing machine 100 of this invention, by adapting to the production rhythm of the automatic box-assembly machine, can directly receive the assembled packaging boxes 200 output by the automatic box-assembly machine, complete the removal of the shaping mold 203 through its own automated process, and then directly transport the processed packaging box 200 to the next production stage, truly realizing a fully automated closed loop of "automatic box assembly - automatic mold removal". This closed-loop design not only eliminates manual connections in the production process, but also improves the continuity and controllability of the overall production line, making it easier for enterprises to manage and monitor the production process in a unified manner, and further promoting the automation upgrade in the packaging production field.
