Description

Technical Field

[0001] This invention relates to the field of packaging film production equipment technology, and more specifically, to a high-efficiency and energy-saving packaging film production equipment. Background Technology

[0002] In the packaging film manufacturing industry, ensuring the quality of packaging films as well as the efficiency and stability of the production process is of paramount importance. Among these factors, effective control of tension during the production of packaging films is one of the key factors in guaranteeing product quality.

[0003] Most existing packaging film production equipment uses pressure sensors to address the stress balance problem between films. While this method can achieve stress balance to some extent, it has many drawbacks.

[0004] Pressure sensor-based control methods require numerous electronic control devices to work together. When adjusting stress balance among multiple shafts, each shaft needs to be equipped with a corresponding sensor and control element, making the entire system structure extremely complex.

[0005] The complex structure leads to a significant increase in costs. The large number of electronic control devices not only increases the procurement cost of the equipment, but also results in high maintenance costs during subsequent use. In addition, due to the large number of electronic control devices, the probability of failure also increases accordingly. Once a component malfunctions, the time and manpower costs required for troubleshooting and repair are not negligible. This affects production efficiency to some extent and increases the company's operating costs.

[0006] Existing pressure sensor-based stress balance control methods for packaging films are difficult to meet the demands of modern packaging film manufacturing for high-efficiency, energy-saving, and low-cost production due to their complex structure and high cost. Therefore, there is an urgent need to develop a new type of high-efficiency and energy-saving packaging film production equipment to simplify the structure, reduce costs, achieve more stable and reliable stress balance control, and improve the production quality and efficiency of packaging films. Summary of the Invention

[0007] The purpose of this invention is to provide a highly efficient and energy-saving packaging film production equipment to solve the problems mentioned in the background art.

[0008] A high-efficiency and energy-saving packaging film production equipment includes a support frame, two pairs of connecting seats are fixedly installed on the lower middle part of the support frame, a protective side plate is fixedly installed on one side of the support frame, a device body is fixedly installed on the other side of the support frame, and a detection device is provided at the upper end of the support frame. The support frame has three support shafts in the middle, and voltage regulator boxes are fixedly installed on both sides of the support frame. The support frame is fixedly installed with a stabilizing component corresponding to the support shaft on the side of the voltage regulator box. A limit frame is slidably provided in the middle of the stabilizing component. A locking component is fixedly installed on the side of the limit frame. A positioning rod is fixedly installed at the lower end of the locking component. The pressure stabilizing box is fixedly installed with a connecting air rod at the corresponding position of the positioning rod. The lower end of the positioning rod is inserted into the interior of the connecting air rod. A small pressure stabilizing pump is fixedly installed at the bottom of the inner cavity of the protective side plate. An electrically controlled pressure relief valve is fixedly installed on the side of the pressure stabilizing box.

[0009] Furthermore, a main control board is fixedly installed on the upper front side of the main body of the device, and a detection platform is fixedly installed on the upper middle part of the protective side plate.

[0010] By adopting the above technical solution, the packaging film can be moved from the top of the inspection table, making it convenient for visual inspection components to inspect the entire packaging film and detect defects in the packaging film.

[0011] Furthermore, a take-up shaft is rotatably mounted in the middle of the connecting seat, and a servo motor is fixedly installed on the side of the take-up shaft inside the main body of the device, with the drive end of the servo motor fixedly connected to the take-up shaft.

[0012] By adopting the above technical solution, the corresponding winding shaft can be driven to rotate by a servo motor, which facilitates the conveying and winding of the packaging film and makes subsequent processing easier.

[0013] Furthermore, the detection device includes a pair of guide rods fixedly installed on the upper end of the support frame, a sliding member slidably disposed in the middle of the guide rods, a drive motor fixedly installed at the upper end of the sliding member, and a vision detection component fixedly installed at the lower end of the sliding member.

[0014] By adopting the above technical solution, the drive motor can drive the control slider to move horizontally within the range of the guide rod, and the vision inspection component can move horizontally, thereby enabling overall inspection of the packaging film on the lower side to reduce the defect rate.

[0015] Furthermore, the side wall of the support frame is provided with a sliding groove corresponding to the limiting frame.

[0016] By adopting the above technical solution, the sliding groove opened on the side wall of the support frame can facilitate the movement of the support shaft, so as to balance the tension exerted by the support shaft on the packaging film.

[0017] Furthermore, a fixing collar is provided on the outer side of the middle part of the positioning rod, and a connecting rod is fixedly installed on the side of the fixing collar. One end of the fixing collar is fixedly connected to the fixing collar, and the other end is fixedly connected to the inner wall of the device body.

[0018] By adopting the above technical solution, the positioning rod can slide in the middle of the fixed collar, and the fixed collar can ensure the stability of the positioning rod's sliding.

[0019] Furthermore, a support mesh plate is fixedly installed in the middle of the connecting air rod, and a limit spring is fixedly installed at one end of the support mesh plate near the positioning rod.

[0020] By adopting the above technical solution, in the pressurized state, the lower end of the positioning rod does not contact the limiting spring. Only when the internal pressure of the pressure stabilizing chamber is abnormal, the positioning rod is pushed by the gravity of the support shaft, and the limiting spring can provide a certain support for the positioning rod.

[0021] Furthermore, a connecting valve is fixedly installed on the lower middle part of the voltage regulator box. One end of the connecting valve is fixedly connected to the output end of the small voltage regulator pump. A voltage regulator chamber is opened in the middle of the inner cavity of the voltage regulator box. A pressure relief groove is opened on the side of the voltage regulator box located on the connecting valve. The voltage regulator chamber and the pressure relief groove are spatially connected. The pressure relief groove is connected to the electrically controlled pressure relief valve.

[0022] By adopting the above technical solution, the small pressure stabilizing pump can pressurize the inside of the pressure stabilizing chamber through the connecting valve. At this time, the internal pressure will push the positioning rod outward, thereby providing a certain support force to the support shaft. When the pressure inside the pressure stabilizing chamber increases, the excessive pressure will pass through the pressure relief groove and be released from the position of the electrically controlled pressure relief valve, thereby achieving dynamic stability of the three support shafts.

[0023] Compared with the prior art, the advantages of this invention are: In this invention, by setting up a structure with a pressure stabilizing box and a stabilizing component, if there is winding stress or excessive stretching inside the packaging film during the production transmission process, the linkage floating structure of the three limiting frames can dynamically adjust the extension and contraction, thereby keeping the transmission of the packaging film stable, achieving more stable and reliable stress balance control, and improving the production quality and efficiency of the packaging film.

The lower end of the positioning rod 15 is inserted into the interior of the connecting air rod 20. A small pressure stabilizing pump 18 is fixedly installed at the bottom of the inner cavity of the protective side plate 2. An electrically controlled pressure relief valve 16 is fixedly installed on the side of the pressure stabilizing box 17. The main control board 6 is fixedly installed on the upper front side of the main body 5, and the inspection table 11 is fixedly installed on the upper middle part of the protective side plate 2. The packaging film 3 can be moved from the upper side of the inspection table 11 to facilitate the visual inspection component 9 to inspect the entire packaging film 3 in order to detect defects in the packaging film 3. A take-up shaft 1 is rotatably mounted in the middle of the connecting seat 4. A servo motor 101 is fixedly installed on the side of the take-up shaft 1 inside the main body 5 of the device. The drive end of the servo motor 101 is fixedly connected to the take-up shaft 1. The servo motor 101 can drive the corresponding take-up shaft 1 to rotate, so that the packaging film 3 can be easily conveyed and wound up, which is convenient for subsequent processing. The inspection device includes a pair of guide rods 8 fixedly installed on the upper end of the support frame 12. A sliding member 801 is slidably arranged in the middle of the guide rods 8. A drive motor 10 is fixedly installed on the upper end of the sliding member 801, and a vision inspection member 9 is fixedly installed on the lower end of the sliding member 801. The drive motor 10 can drive and control the sliding member 801 to move horizontally within the range of the guide rods 8. The vision inspection member 9 can move horizontally, thereby enabling overall inspection of the packaging film 3 on the lower side to reduce the defect rate. The side wall of the support frame 12 is provided with a sliding groove 1201 corresponding to the limiting frame 14. The sliding groove 1201 provided on the side wall of the support frame 12 can facilitate the movement of the support shaft 7 to balance the tension applied by the support shaft 7 to the packaging film 3. A fixing collar 21 is provided on the outer side of the middle part of the positioning rod 15. A connecting rod 22 is fixedly installed on the side of the fixing collar 21. One end of the fixing collar 21 is fixedly connected to the fixing collar 21, and the other end is fixedly connected to the inner wall of the device body 5. The positioning rod 15 can slide in the middle of the fixing collar 21, and the fixing collar 21 can ensure the stability of the sliding of the positioning rod 15. A support mesh plate 24 is fixedly installed in the middle of the connecting air rod 20. A limit spring 23 is fixedly installed at one end of the support mesh plate 24 near the positioning rod 15. In the pressurized state, the lower end of the positioning rod 15 does not contact the limit spring 23. Only when the internal pressure of the pressure stabilizing chamber 27 is abnormal, the positioning rod 15 is pushed by the gravity of the support shaft 7. The limit spring 23 can provide a certain support for the positioning rod 15. A connecting valve 25 is fixedly installed on the lower middle part of the pressure stabilizing box 17. One end of the connecting valve 25 is fixedly connected to the output end of the small pressure stabilizing pump 18.

The pressure stabilizing chamber 27 and the pressure relief groove 26 are spatially connected. The pressure relief groove 26 is connected to the electrically controlled pressure relief valve 16. The small pressure stabilizing pump 18 can pressurize the inside of the pressure stabilizing chamber 27 through the connecting valve 25. At this time, the internal pressure will push the positioning rod 15 outward, thereby providing a certain support force for the support shaft 7. When the pressure inside the pressure stabilizing chamber 27 increases, the excessive pressure will pass through the pressure relief groove 26 and be released from the position of the electrically controlled pressure relief valve 16, thereby achieving dynamic stability of the three support shafts 7.

[0030] Working principle of the invention: A servo motor 101 is fixedly installed inside the main body 5 on the side of the winding shaft 1 in the middle of the connecting seat 4. The driving end of the servo motor 101 is connected to the winding shaft 1. The servo motor 101 drives the winding shaft 1 to rotate, providing power for the conveying and winding of the packaging film 3, which facilitates subsequent processing. The inspection device includes a pair of guide rods 8 fixed to the upper end of the support frame 12. A sliding member 801 in the middle of the guide rods 8 can move horizontally within its range. A drive motor 10 is installed at the upper end of the sliding member 801, and a vision inspection member 9 is installed at the lower end. The drive motor 10 controls the movement of the sliding member 801, thereby driving the vision inspection member 9 to move horizontally. The packaging film 3 moves above the inspection platform 11 in the middle of the upper side of the protective side plate 2. During the movement, the vision inspection member 9 performs an overall inspection of the packaging film 3 below to detect defects on the packaging film 3 and reduce the defect rate. The main control board 6 at the upper front of the main body 5 may be used to control the inspection device and other components, and to process the inspection data fed back by the vision inspection member 9. A small pressure-stabilizing pump 18 at the bottom of the inner cavity of the protective side plate 2 pressurizes the pressure-stabilizing chamber 27 in the middle of the inner cavity of the pressure-stabilizing box 17 through a connecting valve 25. Stabilizing components 13 are provided on both sides of the pressure-stabilizing box 17 corresponding to the support shafts 7. A limiting frame 14 is slidably installed in the middle of the stabilizing component 13. The limiting frame 14 is connected to the positioning rod 15 through a snap-fit ​​component 19. The lower end of the positioning rod 15 is inserted into the connecting air rod 20 on the pressure-stabilizing box 17. When the pressure-stabilizing chamber 27 is pressurized, the internal pressure pushes the positioning rod 15 outward, thereby providing support for the support shafts 7. The three positioning rods 15 share one pressure-stabilizing chamber 27. When the pressure-stabilizing chamber 27 is constant, the support shafts 7 on its three sides are in a dynamic equilibrium state. The outer packaging film 3 is provided with stable support. The thrust of the support shaft 7 is in balance with the stress when the packaging film 3 is pulled. At this time, the packaging film 3 is stretched normally. In the normal state, the limiting frame 14 is in the middle position of the stabilizer 13. When the packaging film 3 is rolled up to be laid out, the packaging film 3 is not rolled up tightly. When the packaging film 3 is suddenly laid out, the pressure on the support shaft 7 from the packaging film 3 decreases. At this time, the pressure inside the pressure stabilizing chamber 27 supports the positioning rod 15 more than the pressure of the limiting frame 14. At this time, the three limiting frames 14 will move outward dynamically to support and push the packaging film 3, so that the packaging film 3 becomes a stable laid-out state without wrinkles. When the winding shaft 1, which drives the transmission, operates at a differential speed, it pulls on both ends of the packaging film 3, causing the packaging film 3 to deform beyond acceptable limits. At this time, the support shaft 7 experiences increased pressure from the packaging film 3, and the three limit frames 14 squeeze towards the inside of the pressure stabilizing chamber 27, increasing the pressure inside the originally stable pressure stabilizing chamber 27. The excess pressure is discharged from the position of the electrically controlled pressure relief valve 16. At this time, the supporting force of the support shaft 7 decreases, forming a buffer. The main control board 6 receives an abnormal signal and can reduce the pressure of the small pressure stabilizing pump 18, thereby preventing the packaging film 3 from being pulled and deformed and damaged. This provides operators with some adjustment space, reduces the scrap rate, and further ensures the stability of the system.
