Description

Technical Field

[0001] This application relates to the field of paper cup processing equipment technology, specifically a paper cup machine with fault prediction function and its usage method. Background Technology

[0002] This paper cup machine uses food-grade coated paper as raw material and integrates automatic paper feeding, die-cutting, cup body winding, heat sealing, cup bottom bonding, edge curling, and finished product output. It employs a PLC programmable controller and multi-axis servo motors for coordinated control, along with a photoelectric sensor and temperature control closed-loop system, to achieve continuous automated paper cup production. The machine mainly consists of a frame, a paper feeding and die-cutting mechanism, a cup body forming device, a double-rotor cup bottom sealing mechanism, a cup rim curling mechanism, and a detection and output system. It can complete the entire process from sheet material to finished paper cup in one go. The workflow includes unwinding and die-cutting of raw paper, cup body winding and heat sealing, cup bottom bonding and sealing, cup rim curling and shaping, and finally, detection, sorting, and output. It features high forming accuracy, fast production speed, reliable bonding and sealing, high automation, and stable operation, effectively improving production efficiency and reducing scrap rates. It is suitable for the large-scale manufacturing of various disposable paper cups.

[0003] Regarding the aforementioned technologies, most existing paper cup machines employ a reactive maintenance model during production, meaning repairs are only carried out after equipment malfunctions and shutdowns. This lack of proactive fault prediction capabilities easily leads to production interruptions and impacts production schedules. Furthermore, some paper cup machines with monitoring functions suffer from several defects in the installation structure of their monitoring sensors: First, sensor installation is cumbersome, requiring tools to tighten bolts individually, resulting in low installation efficiency. Over time, the bolts tend to loosen, causing sensor misalignment and distorted monitoring data. Second, the fixed sensor positions and angles cannot be adjusted according to different production needs and paper cup sizes, leading to blind spots in monitoring. This prevents comprehensive coverage of key nodes in the production process, hinders accurate detection of abnormal states, and ultimately, impairs accurate fault prediction. Third, adjusting the monitoring position requires disassembling and reinstalling the sensors, a cumbersome process that impacts production efficiency, reduces the timeliness and accuracy of fault prediction, and increases the risk of missed detections, leading to higher scrap rates and even equipment shutdowns, further disrupting production continuity.

[0019] To better understand the above technical solution, the following will refer to the appendix to the instruction manual. Figure 1-13 The specific implementation methods are described in detail for the above technical solutions.

[0020] refer to Figure 1 and Figure 3This application discloses a paper cup machine with fault prediction function, including a frame 1, a storage rack 2, a cup body forming section 3, a cup bottom forming section 4, a transmission section 5, and a dynamic monitoring mechanism 6. The frame 1 is the main supporting structure of the entire equipment, used to support various functional components. The storage rack 2 is located at one end of the frame 1 and is used to store coated paper sheets to be processed, providing raw materials for production. The cup body forming section 3 is located at the upper end of the frame 1 and is used to wind and heat-seal the paper sheets to form the cup body. The cup bottom forming section 4 is located on one side of the cup body forming section 3 and is used to process the cup bottom of the paper cup, bond the cup bottom to the cup body, and simultaneously complete the edge forming of the cup rim. The transmission section 5 is located inside the frame 1 and is used to provide power transmission to various functional components, driving the components to operate collaboratively and achieve continuous automated production. The dynamic monitoring mechanism 6 is located at the upper end of the frame 1 and near the storage rack 2, used to monitor the raw paper sheets and equipment operating status in real time during production, collect relevant data, and achieve early fault prediction.

[0021] Before paper cup production, the dynamic monitoring mechanism 6 must be installed on the frame 1, and corresponding sensors are simultaneously equipped on the transmission unit 5 to monitor the paper cup machine's operating status in real time. Pre-processed coated paper sheets are placed in the storage rack 2 and then conveyed to the paper cup forming unit via the transmission unit 5. The dynamic monitoring mechanism 6 monitors the output posture of the paper sheets in real time, promptly identifies abnormal states, and issues warnings through other devices connected to the processor, facilitating operator handling of abnormal paper sheets. Normal paper sheets are processed into cylindrical cup bodies by the cup body forming unit 3, and then the cup bottom is installed by the cup bottom forming unit 4, thus completing the paper cup processing. Sensors in the transmission unit 5 monitor gear rotation and belt condition, proactively assessing the gear and belt status to prevent gear jamming, belt fatigue breakage, or loosening.

[0022] refer to Figures 3 to 10 The dynamic monitoring mechanism 6 includes a dustproof top cover 61, a fixed base 62, a fixing clamp 63, a mounting arm 64, a fastening assembly 65, a housing 66, an angle adjustment assembly 67, a height adjustment assembly 68, and a sensor body 7. The dustproof top cover 61 is fixedly installed on the upper end of the frame 1 to protect the monitoring components below, preventing dust and paper scraps from entering the components during production and affecting their normal operation. The fixed base 62 is fixedly installed on the lower end of the dustproof top cover 61 to support the fixing clamp 63. The fixing clamp 63 is fixedly installed on one side of the fixed base 62, and is supported by… Figure 3 , Figure 8It can be seen that the two ends of the fixing base 62 and the fixing clamp 63 are fixedly connected. The fixing clamp 63 is a horizontal beam structure on one side of the fixing base 62. The fixing base 62 and the fixing clamp 63 are actually an integrated component. A fixing slot 631 is provided on the inner side of the fixing clamp 63. The fixing slot 631 is used to insert the mounting arm 64. Multiple mounting arms 64 are evenly distributed along the length of the fixing clamp 63. Each mounting arm 64 can be installed independently, which facilitates the addition or removal of the sensor body 7 according to monitoring needs. One end of the mounting arm 64 is provided with a fixing insert 641. The fixing insert 641 is used to insert into the fixing slot 631. Figure 4 , Figure 8 As can be seen, the fixing plate 641 is inserted into the fixing slot 631 through the side opening of the fixing slot 631, thereby achieving the initial positioning of the mounting arm 64. The fastening component 65 is disposed between the fixing plate 641 and the fixing base 62, and is used to fix the fixing plate 641 inserted into the fixing slot 631, thereby completing the fixed installation of the mounting arm 64. The housing 66 is sleeved on the outside of the mounting arm 64, and is used to install the sensor body 7, and also to accommodate the adjustment component. The sensor body 7 is disposed at the lower end of the housing 66, and is used to collect monitoring data, including paper shape data, equipment vibration data, etc., to provide data support for fault prediction.

[0023] The fastening assembly 65 includes a fastening bolt 651, a fastening cover plate 652, a first protrusion 653, a lever 654, a first rotating rod 655, and a second protrusion 656. The fastening bolt 651 is threadedly connected to the fixing insert plate 641. Figure 5 It can be seen that the lower end of the fastening bolt 651 is inserted into the mounting hole on the fixing plate 641 to provide the power for tightening. The fastening cover plate 652 is fitted over the outside of the fastening bolt 651 and is used to press the first protrusion 653 when the fastening bolt 651 is tightened. The first protrusion 653 is embedded inside the fixing plate 641 and located inside the fastening cover plate 652. When the fastening bolt 651 is tightened, the fastening cover plate 652 presses the first protrusion 653, causing it to move inward into the fixing plate 641. A lever 654 is located at the lower end of the first protrusion 653, and one end of the lever 654 is rotatably connected to the first protrusion 653. Figure 9 It can be seen that the second protrusion 656 is located on the upper end face of the fixed insert plate 641 and near the mounting arm 64, and is combined with Figure 9 , Figure 5As can be seen, the second protrusion 656 is located below the fixed clamping plate 63. The other end of the lever 654 is rotatably connected to the second protrusion 656. The first rotating rod 655 is positioned between the first protrusion 653 and the second protrusion 656, and is rotatably connected to the lever 654, serving as the fulcrum of the lever 654. The first rotating rod 655 is inserted into a mounting hole on the surface of the lever 654, and the distance between the first rotating rod 655 and the first protrusion 653 is greater than the distance between the first rotating rod 655 and the second protrusion 656. This arrangement makes the lever 654 a force-saving lever. When the first protrusion 653 is subjected to a small compressive force, it can drive the second protrusion 656 to generate a large clamping force, ensuring the firmness of the fixation. At the same time, the mass of the first protrusion 653 is less than the mass of the second protrusion 656, ensuring the balance of the lever 654 and preventing loosening.

[0024] When installing the mounting arm 64, first insert the fixing plate 641 into the fixing slot 631 inside the fixing clamp 63. Then, place the fastening cover plate 652 on the fixing plate 641 and insert the fastening bolt 651 into the threaded hole on the fastening cover plate 652. Adjust the mounting arm 64 to the installation position according to the preset point, and then tighten the fastening bolt 651. When the fastening bolt 651 is tightened, the fastening cover plate 652 presses against the first protrusion 653. The first protrusion 653 drives one end of the lever 654 to move inward. The lever 654 rotates around the first rotating rod 655 as the fulcrum, driving the second protrusion 656 at the other end to move upward. The upper end of the second protrusion 656 passes through the fixing plate 641 and finally abuts against the outer wall of the fixing clamp 63. The fastening force achieves a firm fixation between the fixing plate 641 and the fixing clamp 63, completing the installation of the mounting arm 64. No additional alignment is required, installation is convenient and secure, preventing loosening after long-term use.

[0025] refer to Figures 10 to 12An angle adjustment component 67 is located inside the housing 66 and near the sensor body 7, used to adjust the orientation of the sensor body 7 and adjust the monitoring angle. The angle adjustment component 67 includes a connecting rod 674, a second gear 673, a first gear 672, a turntable 671, a limiting roller 675, and a reset spring 676. The connecting rod 674 is fixedly installed on the upper end of the sensor body 7, and its upper end passes through the housing 66, extending into the interior of the housing 66, to drive the sensor body 7 to rotate. The second gear 673 is fixedly installed on the upper end of the connecting rod 674 and rotates coaxially with it. The first gear 672 meshes with the outside of the second gear 673; when the first gear 672 rotates, it drives the second gear 673 to rotate, thereby driving the connecting rod 674 and the sensor body 7 to rotate. The turntable 671 is located on the upper end of the first gear 672 and is coaxial with the first gear 672. A through groove is provided on the outer side wall of the box 66 near the turntable 671. Some of the teeth of the turntable 671 are located outside the box 66. The operator can directly turn the turntable 671 from outside the box 66 to drive the first gear 672 to rotate.

[0026] The radius of the first gear 672 is smaller than that of the second gear 673. The gear set formed by the second gear 673 and the first gear 672 is a reduction gear set. This arrangement results in the second gear 673 rotating more slowly when the operator turns the dial 671, allowing for higher adjustment precision and accurate adjustment of the orientation of the sensor body 7, avoiding over-adjustment. Simultaneously, a limiting roller 675 is provided on the outer side of the first gear 672. The limiting roller 675 engages between two adjacent teeth of the first gear 672 to limit its rotation, preventing it from rotating on its own and ensuring the adjusted angle remains stable. The reset spring 676 is located inside the housing 66 and near the limiting roller 675. It has an arc-shaped structure, and both ends of the reset spring 676 are slidably connected to the inner sidewall of the housing 66. The limiting roller 675 is rotatably mounted on the protrusion in the middle of the reset spring 676. The reset spring 676 can provide elastic clamping force to the limiting roller 675, ensuring that the limiting roller 675 can always be engaged between the teeth of the first gear 672. At the same time, when the operator moves the turntable 671, the limiting roller 675 can compress the reset spring 676 under the pressure of the teeth, realizing the rotation of the turntable 671. After the adjustment is completed, the reset spring 676 pushes the limiting roller 675 to re-engage between the teeth, completing the limiting.

[0027] refer to Figure 10 and Figure 13The height adjustment component 68 is located inside the housing 66 and near the partition 661. The partition 661 is fixed inside the housing 66 and separates the angle adjustment component 67 and the height adjustment component 68 to prevent interference between the two components. The height adjustment component 68 is used to adjust the height of the housing 66 on the mounting arm 64, thereby adjusting the height of the sensor body 7 and adjusting the monitoring height position. The height adjustment component 68 includes a knob 681, a second rotating rod 682, a third gear 683, a fourth gear 684, a third rotating rod 685, a fifth gear 686, and a gear plate 642. The knob 681 is inserted into the outside of the housing 66, allowing the operator to rotate it from the outside. The second rotating rod 682 is located at one end of the knob 681 and is coaxial with the knob 681. Rotating the knob 681 will drive the second rotating rod 682 to rotate. The third gear 683 is sleeved on the second rotating rod 682 and rotates coaxially with it. The fourth gear 684 is meshed with the outer side of the third gear 683. When the third gear 683 rotates, it drives the fourth gear 684 to rotate. The third rotating rod 685 is inserted into the inner side of the fourth gear 684 and is coaxial with the fourth gear 684, used to support the fourth gear 684. The fifth gear 686 is meshed with the outer side of the fourth gear 684. When the fourth gear 684 rotates, it drives the fifth gear 686 to rotate. The toothed plate 642 is set on the outer wall of the mounting arm 64. The fifth gear 686 is meshed with the toothed plate 642. When the fifth gear 686 rotates, it rolls along the toothed plate 642, thereby driving the housing 66 to rise and fall along the mounting arm 64, realizing the adjustment of the height of the sensor body 7.

[0028] The radius of the third gear 683 is smaller than the radius of the fourth gear 684, and the radius of the fourth gear 684 is smaller than the radius of the fifth gear 686. The gear set composed of the third gear 683, the fourth gear 684, and the fifth gear 686 is a reduction gear set. This setting makes the lifting speed of the box 66 slower and the adjustment precision higher when the operator turns the knob 681. It can accurately adjust the height of the sensor body 7 and ensure that the sensor body 7 can be aligned with the monitoring area.

[0029] A method for using a paper cup machine with fault prediction function includes the following steps: S1. Slide the housing 66 on the sensor body 7 onto the mounting arm 64, insert the fixing plate 641 into the fixing slot 631, place the fastening cover plate 652 and tighten the fastening bolt 651, and by squeezing the first protrusion 653, use the lever to lift the second protrusion 656 to abut against the fixing clamp 63, thus completing the fixing of the mounting arm 64. S2. Move the turntable 671 on the outside of the box 66 to adjust the orientation of the sensor body 7 through the transmission of the first gear 672 and the second gear 673, so that the probe is aligned with the preset monitoring area; S3. Rotate knob 681, which drives third gear 683 through second lever 682, and then drives box 66 to rise and fall along toothed plate 642 through engagement of fourth gear 684 and fifth gear 686, adjusting the height of sensor body 7 to align with the monitoring area; S4. During the process of introducing paper sheets into the cup body forming part 3 from the storage rack 2, the sensor body 7 monitors the shape in real time. When there is an abnormality, it is recorded and uploaded to the processor, and the connected equipment prompts the operator to remove the abnormal paper sheets. S5. The processor analyzes the real-time data collected by the sensor body 7, combines the preset fault threshold with historical operating data, predicts the possible fault types and times of the equipment, and sends early warning information to the operators in advance so that timely inspection and maintenance can be carried out.

[0030] The working principle of this application embodiment is as follows: When installing the sensor body 7, firstly, the housing 66 is fitted onto the mounting arm 64. Then, the fixing plate 641 at one end of the mounting arm 64 is inserted into the fixing slot 631 on the fixing clamp 63 to complete the initial positioning. Subsequently, the fastening cover 652 is fitted onto the fastening bolt 651, and the fastening bolt 651 is tightened. During the tightening process, the fastening cover 652 will press against the first protrusion 653, causing the first protrusion 653 to move inward into the fixing plate 641, which in turn causes one end of the lever 654 to move inward. The lever 654 rotates around the first rotating rod 655 as a fulcrum, causing the second protrusion 656 at the other end to move upward. The upper end of the second protrusion 656 abuts against the outer wall of the fixing clamp 63, and the mounting arm 64 is firmly fixed through the tightening force, thus completing the installation of the sensor body 7.

[0031] After installation, adjust the position of the sensor body 7 according to production needs: Move the turntable 671 on the outside of the housing 66. The turntable 671 drives the first gear 672 to rotate, which in turn drives the second gear 673 to rotate, thereby rotating the connecting rod 674 and the sensor body 7. Adjust the orientation of the sensor body 7 so that its probe is aligned with the area to be monitored. During adjustment, the limit roller 675, under the action of the reset spring 676, remains engaged between the teeth of the first gear 672, ensuring the stability of the adjusted angle. Then rotate the knob 681. The knob 681 drives the second rotating rod 682 and the third gear 683 to rotate, which in turn drives the fourth gear 684 to rotate, which in turn drives the fifth gear 686 to rotate. The fifth gear 686 rolls along the toothed plate 642 on the mounting arm 64, causing the housing 66 to rise and fall along the mounting arm 64, adjusting the height of the sensor body 7 so that it is aligned with the monitoring area, thus completing the adjustment of the monitoring position.

[0032] During production, paper sheets on the storage rack 2 are fed into the cup forming section 3. The sensor body 7 monitors the shape of the paper sheets and the operating status of the equipment in real time, collects relevant data, and uploads the data to the processor. The processor analyzes the collected real-time data, combines it with preset fault thresholds and historical operating data to determine if there are any abnormal conditions. When abnormalities such as wrinkles or misalignment are detected in the paper sheets, the processor will promptly alert the operator to remove the abnormal paper sheets and avoid generating waste. At the same time, the processor will predict the types and timing of possible equipment failures based on data trends and send early warning information to the operator in advance so that the operator can carry out timely inspection and maintenance, avoid equipment failure and downtime, and ensure the continuity of production.

[0033] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this application. The scope of this application is defined by the appended claims and their equivalents.
