Description

Technical Field

[0001] This utility model relates to the technical field of paper and plastic product manufacturing equipment, and in particular to an automatic production line for a hot press. Background Technology

[0002] In the production of paper-plastic (such as paper trays) products, hot pressing (hot pressing shaping) is a crucial process. Its purpose is to use hot pressing molds to press, heat, shape, and trim the wet or semi-dry blanks after molding, resulting in a final product with a smooth shape and stable dimensions. Currently, this process mainly takes two forms: Manual Operation Mode: This is a more traditional production method, in which operators manually place the workpieces to be processed into the lower mold of the hot press, start the equipment to complete the hot pressing, and then manually remove the finished product and separate the waste material. This mode has significant drawbacks: First, it requires a large workforce and has high labor costs; second, direct manual intervention in the mold-closing area of ​​the equipment poses a high risk of mechanical injury and safety, making it difficult to meet stringent industrial safety standards (such as CE certification requirements); third, the cycle time of manual operation is unstable, resulting in low production efficiency and difficulty in ensuring consistent product quality.

[0003] Semi-automation mode: To improve efficiency, some companies have adopted equipment with simple conveyor belts or robotic arms. However, existing automation solutions often suffer from low integration and poor flexibility. In particular, the core hot press equipment's mold closing height adjustment typically relies on manually adding or removing shims, a cumbersome and inaccurate process that cannot quickly adapt to the changing needs of molds of different heights, impacting the flexibility and efficiency of the production line. Furthermore, existing hot presses have poor cushioning performance, easily causing impacts to the mold and equipment at the moment of mold closing, affecting mold life and product molding quality. The various units in the production line (such as feeding, hot pressing, unloading, waste disposal, and finished product stacking) mostly operate independently, lacking an efficient and coherent material flow design, failing to achieve truly fully automated assembly line operations.

[0004] There is a need in this field for a highly integrated, automated, easy-to-adjust, and safe and reliable automatic production line for hot presses to solve the problems of low production efficiency, poor safety, insufficient flexibility, and poor connection between various processes in the existing technologies.

[0019] Reference Figure 1-7 According to a first aspect of the present invention, an automatic production line for a hot press 300 is characterized in that it includes, in sequence, a feeding and humidifying conveyor line 100, a feeding robot 200, a hot press 300, a waste conveyor line 400, a material handling robot 500, a finished product conveyor line 600, and a finished product unloading platform 700. By integrating and connecting the feeding and humidifying conveyor line 100, the feeding robot 200, the hot press 300, the material handling robot 500, the waste conveyor line 400, the finished product unloading platform 700, and the finished product conveyor line 600 in sequence, a complete automated production line is constructed. This achieves fully unmanned operation from workpiece loading, positioning, hot pressing and shaping, waste separation to finished product stacking and output, significantly improving production efficiency, greatly reducing labor costs and operational safety risks, and meeting modern industrial safety standards.

[0020] The feeding and humidifying conveyor line 100 includes a feeding conveyor platform 110 and feeding conveyor chains 120 arranged on both sides of the feeding conveyor platform 110. A pusher rod for pushing the material to move on the feeding conveyor platform 110 is arranged between the two sides of the feeding conveyor chains 120. A feeding drive motor 130 for driving the feeding conveyor chains 120 is arranged at one end of the feeding conveyor platform 110. The feeding and humidifying conveyor line 100 integrates humidification function, which can meet the necessary process requirements before hot pressing of paper and plastic products. The feeding robot 200 has an adsorption device 210 installed at its end for adsorbing workpieces. The feeding robot 200 uses the adsorption device 210 to grasp the workpieces. Compared with traditional mechanical grippers, this non-contact gripping method does not damage the workpiece surface and is particularly suitable for easily deformable workpieces such as paper and plastic or workpieces with high surface precision requirements. At the same time, the adsorption device 210 has better flexibility and can adapt to the stable gripping of workpieces of different shapes within a certain size range, which improves the reliability of the feeding process and the flexibility of the production line.

[0021] The hot press 300 includes the following components: A frame 310 is provided, on which a base plate 311 is fixedly installed. A plurality of guide posts 312 are erected on the base plate 311, and a top plate 313 is movably sleeved on the plurality of guide posts 312. An adjusting lifting mechanism 320, used to adjust the mold closing height, is located on the upper part of the frame 310 and mounted on the top plate 313. Several threaded sleeves 321 are rotatably fitted inside the top plate 313 via bearings. A driven sprocket 322 is fixedly mounted on the upper end of each threaded sleeve 321. A screw 323 is screwed into the inside of each threaded sleeve 321. The bottom end of the screw 323 is integrally formed with the top end of the guide post 312. The adjusting lifting mechanism 320 also includes a first motor 324. A driving sprocket 325 is fixedly mounted on the shaft of the first motor 324. A chain 326 is wound around the several driven sprockets 322. 325 is engaged with the chain 326; by adopting an adjustment and lifting mechanism 320 driven by a first motor 324, which synchronously drives the threaded sleeve 321 to rotate through the active sprocket 325, the chain 326 and several passive sprockets 322, and thus causes the screw 323, which is integrally formed with the guide post 312, to move linearly relative to the threaded sleeve 321, the motorized, precise and synchronous adjustment of the mold closing height is realized. This not only makes the operation convenient and labor-saving, but also overcomes the defects of low efficiency and poor accuracy of the traditional shim adjustment method. It also effectively ensures the synchronicity and stability of the adjustment of each point of the upper mold assembly, and significantly improves the adaptability of the equipment to different molds and the reliability of the whole machine operation.

[0022] The upper mold heating plate 334 assembly 330 is located below the top plate 313 and includes a movable plate 331 and an upper template 332 installed on the lower part of the movable plate 331. The movable plate 331 is provided with several sliding sleeves 333 that are movably sleeved and installed on the guide post 312. A rotatable shaft is provided through the upper part of the movable plate 331, and the two ends of the shaft extend to the outside of the movable plate 331. By setting the movable plate 331 with sliding sleeves 333 and the guide post 312 to form a sliding guide pair, it is ensured that the upper mold heating plate 334 assembly 330 moves smoothly along a fixed trajectory during the lifting process without the risk of deviation or jamming. At the same time, the shaft provided through the movable plate 331 provides a reliable power input connection point for the swing arm 353, so that the power of the lifting drive group 350 can be smoothly and evenly transmitted to the entire upper mold assembly, thereby ensuring the accuracy of hot pressing and the consistency of product molding quality.

[0023] The lower mold heating plate 334 assembly is located directly below the upper mold heating plate 334 assembly 330 and is disposed on the base plate 311. It includes a lower mold plate 341 and a spring buffer mechanism 342 installed between the lower mold plate 341 and the base plate 311. The spring buffer mechanism 342 includes a plurality of vertically installed compression springs 343. By setting the spring buffer mechanism 342 containing a plurality of vertical compression springs 343 between the lower mold plate 341 and the base plate 311, the upper mold can effectively absorb and buffer the impact energy through the compression deformation of the springs when it is pressed down, which greatly reduces the rigid collision and noise at the moment of mold closing. This not only protects the mold and equipment structure and extends their service life, but also ensures that the product is subjected to more uniform and stable force during the hot pressing process, effectively improving the final molding quality and consistency of the product.

[0024] The lifting drive assembly 350, used to drive the upper mold heating plate 334 assembly 330 to perform lifting and lowering movements, is mounted on the top plate 313. The lifting drive assembly 350 includes a second motor 351 mounted in the middle of the top plate 313, a deflector wheel 352 mounted on the rotating shaft of the second motor 351, and a swing arm 353 rotatably mounted at both ends of the deflector wheel 352 and the rotating shaft, respectively. The lifting drive assembly 350 drives the deflector wheel 352 and the swing arm 353 through the second motor 351 to realize the lifting and pressing movements of the upper mold heating plate 334 assembly 330. The lifting drive assembly 350 uses the mechanism of the second motor 351 driving the deflector wheel 352 and the swing arm 353 to drive the upper mold assembly to lift and lower. Combined with the spring buffer mechanism 342 below the lower mold assembly, it forms a pressure system with smooth operation and excellent buffering performance. This structure effectively reduces rigid impact and equipment noise at the moment of mold closing, protecting the mold and mechanical structure, extending the service life of the equipment, and providing a stable pressure environment for product molding, thus ensuring consistent product quality.

[0025] The hot press 300 employs an adjustable lifting mechanism 320, which, through a single first motor 324 driving a sprocket and chain system 326, simultaneously rotates multiple threaded sleeves 321, thereby precisely adjusting the initial height of the top plate 313 and the entire upper mold assembly. This motor-driven adjustment method replaces the traditional manual shim adjustment, making the adjustment of the mold closing height more convenient and precise, greatly enhancing the adaptability to molds of different heights, and improving the flexibility of the production line.

[0026] The waste conveyor line 400 includes a waste conveyor frame 410 and a waste conveyor belt 420 mounted on the waste conveyor frame 410. One end of the waste conveyor frame 410 is equipped with a waste drive motor 430 that drives the waste conveyor belt 420. The dedicated waste conveyor line 400 automatically collects and removes waste materials, keeping the work area clean. The finished product unloading platform 700, in conjunction with the finished product conveyor line 600, enables automatic stacking and transfer of finished products, further reducing manual intervention and ensuring smooth logistics throughout the line with a higher degree of automation.

[0027] The material handling robot 500 and the feeding robot 200 are respectively set on both sides of the hot press 300. By setting the feeding robot 200 and the material handling robot 500 on both sides of the hot press 300 and equipping them with adsorption devices 210 for workpiece gripping, the spatial separation and temporal connection of the loading and unloading processes are realized. This not only avoids the problem of interference in the operation path of a single robot and improves cycle efficiency, but also ensures that the adsorption device 210 does not damage the surface of the paper-plastic workpiece during the gripping process. The two work together to significantly improve the smoothness and reliability of the entire automated operation line.

[0028] The finished product conveyor line 600 includes a finished product conveyor frame 610 and a finished product conveyor belt 620 mounted on the finished product conveyor frame 610. One end of the finished product conveyor frame 610 is equipped with a finished product drive motor 630 that drives the finished product conveyor belt 620. By setting up the finished product conveyor line 600, which consists of the finished product conveyor frame 610, the finished product conveyor belt 620, and the finished product drive motor 630, an efficient and stable automated output path is provided for qualified products after hot pressing and shaping. It achieves seamless connection with the operation of the aforementioned finished product unloading table 700, and together they form a complete finished product unloading process. This effectively avoids the efficiency bottleneck and potential damage caused by manual handling, and further improves the automation level and continuous operation capability of the entire production line.

[0029] A finished product unloading platform 700, located at one end of the finished product conveyor line 600, includes a finished product unloading rack 710 and a platform 720 on the rack 710. The platform 720 is equipped with a movable plate 730 for pushing finished products onto the finished product conveyor line 600. By setting up the finished product unloading platform 700 with the platform 720 and the movable plate 730, temporary storage and automatic stacking of finished products on the platform 720 are achieved. The movable plate 730 smoothly pushes the stacked finished product groups into the finished product conveyor line 600, effectively connecting the intermittent receiving and continuous conveying stages, avoiding manual transfer, and further improving the automation level and overall efficiency of the end-of-line operation.

[0030] An automated hot press production line 300 according to an embodiment of this utility model has at least the following beneficial effects: By integrating a feeding and humidifying conveyor line 100, a feeding robot 200, a hot press 300, a material handling robot 500, a waste conveyor line 400, a finished product unloading platform 700, and a finished product conveyor line 600, a complete fully automated production line is constructed. This achieves fully unmanned operation from workpiece loading, positioning, hot pressing and shaping, waste separation to finished product stacking and output, significantly improving production efficiency and greatly reducing labor costs and operational safety risks. The hot press 300 meets industrial safety standards. In particular, the hot press 300 adopts an adjustable lifting mechanism 320 driven by a motor, sprocket and chain 326, which can conveniently and accurately adjust the mold closing height, enhancing the adaptability of the equipment to different molds. The lifting drive group 350 based on the bias wheel 352 and the swing arm 353, together with the spring buffer mechanism 342 of the lower mold, makes the hot pressing process run smoothly and has a good buffering effect, effectively reducing equipment impact and noise, extending the service life of the mold and equipment, and ensuring the stability and consistency of product molding quality.

[0031] According to some embodiments of this utility model, a humidification device 140 is provided on the feeding conveying platform 110. The humidification device 140 contains several humidification pipes, and several nozzles 141 are installed on the humidification pipes. By integrating the humidification device 140 during the feeding stage, the surface of the paper-plastic workpiece can be uniformly and appropriately moisturized before hot pressing. This effectively avoids problems such as cracking, deformation, or poor surface finish during hot pressing due to excessive dryness of the workpiece, ensuring the molding quality and consistency of the final product.

[0032] According to some embodiments of this utility model, a stacking detection device for detecting the stacking height of finished products is provided on the platform 720 of the finished product unloading table 700. By monitoring the stacking height of the finished products in real time through the stacking detection device, subsequent actions (such as a cylinder pushing a moving plate 730) can be automatically triggered when a preset height is reached, realizing fully automatic connection between stacking and transfer processes without manual intervention or monitoring, further improving the automation level of the production line. This device can accurately determine the stacking completion status, avoiding wasted cycle time due to waiting for manual confirmation or inaccurate timer estimation, ensuring continuous, stable, and efficient operation of the production line. Precise height detection effectively prevents finished products from tipping over, being squeezed and deformed, or causing overload damage to the unloading table and pushing mechanism due to excessive stacking, providing safety protection and ensuring the reliability of equipment operation. The signals provided by the stacking detection device (such as a photoelectric sensor or limit switch) can be connected to the production line's central control system, facilitating production counting, data recording, and process monitoring, providing a foundation for intelligent production management.

[0033] According to some embodiments of this utility model, a cylinder pushing mechanism 740 for driving the movement of the moving plate 730 is installed at the bottom of the finished product unloading rack 710. Using a cylinder as the driving source has the advantages of simple structure, large output force, and rapid and reliable action, ensuring sufficient power to smoothly and reliably push stacked finished product groups of a certain weight into the finished product conveyor line 600, avoiding jamming or pushing failure due to insufficient pushing force. The movement of the cylinder is controlled by a solenoid valve, which can be easily connected to the electrical control system, with rapid response and simple control logic. This allows it to efficiently receive signals from sensors such as stack detection devices, realizing automated sequence control of "pushing when full is detected," seamlessly integrating into the entire automated production line process. The linear motion characteristics of the cylinder, combined with the moving plate 730, provide a smooth linear thrust, allowing the finished product stack to be moved horizontally onto the conveyor line. This smooth pushing method effectively reduces the risk of finished product stack collapse or product damage during transfer, ensuring finished product quality. Installing the cylinder pushing mechanism 740 at the bottom of the unloading rack is a reasonable layout, does not occupy extra space, and makes the equipment structure compact. Meanwhile, pneumatic components are highly standardized, easy to maintain and replace, reducing the maintenance costs of the equipment in the later stages.

[0034] According to some embodiments of this utility model, the bottoms of the feeding conveyor platform 110, the waste conveyor rack 410, the finished product conveyor rack 610, and the finished product unloading rack 710 are all equipped with rollers. The rollers allow for easy movement of each functional unit in the production line (such as the feeding conveyor platform 110, the waste conveyor rack 410, the finished product conveyor rack 610, and the finished product unloading rack 710). Users can quickly and flexibly adjust the layout or spacing of the entire production line according to the actual space in the workshop and the needs of optimizing the production process, avoiding the limitations and inconveniences of traditional fixed installation. During initial equipment installation or subsequent maintenance and repair, operators can easily move individual units out of their workstations, providing ample space for operation and maintenance, significantly reducing installation difficulty and maintenance intensity. Simultaneously, the easily movable equipment facilitates thorough cleaning of the bottom and surrounding areas of the production line. This design provides convenience for future production line expansion or process changes. If new functional modules need to be added or the process flow adjusted, existing units can be easily rearranged, giving the production line good scalability and enabling it to quickly adapt to changes in production capacity or product iteration needs.

[0035] The embodiments described above with reference to the accompanying drawings have been described in detail. However, the embodiments are not limited to those described above. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the invention.
