Description

Technical Field

[0001] This utility model relates to the technical field of edge sealing devices, specifically an environmentally friendly and energy-saving bag sealing device. Background Technology

[0002] In the bag-making process of the packaging industry, edge sealing is a core process that determines the bag's sealing performance, strength, and product quality. Currently, the mainstream bag-sealing devices on the market are mainly divided into three categories: heat-fusion type, ultrasonic type, and needle-sewing type. Among them, the heat-fusion type accounts for over 60% of applications in low- to mid-range bag-making production lines due to its simple structure and wide range of applicable materials (such as polyethylene, polypropylene, and other plastic films and composite films). However, existing heat-fusion sealing devices have the following prominent problems in actual use: The edge banding quality is unstable and prone to deviations and damage. Existing equipment lacks effective guiding and holding mechanisms when conveying materials to be sealed. The material is prone to displacement due to fluctuations in conveying speed and uneven tension, resulting in skewed sealing positions. In addition, the contact between the sealing plate and the material is mostly a rigid collision without a buffer structure. For thin or easily stretchable film materials, this can easily cause excessive local stress and breakage; while for thicker materials, insufficient pressure may lead to weak fusion and cracking of the sealing edge. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are: the design of this environmentally friendly and energy-saving bag sealing device is reasonable; This device concentrates heat energy on the edge-sealing area by setting an independent heating chamber within the heating element under the edge sealing, and embedding the heating wire inside. This reduces heat loss to the external environment, improving energy utilization by more than 35% compared to traditional integral heating blocks, significantly reducing energy consumption. Simultaneously, the precise matching design between the heating wire and the material avoids localized overheating and carbonization, reducing odor and VOC emissions, meeting environmental protection production requirements. Furthermore, the edge-sealing structure of the heating chamber reduces contamination of the heating element by external dust and impurities, extending its service life. The edge-sealing components on both sides of the upper edge-sealing plate achieve flexible contact during edge sealing through the cooperation of buffer bodies and buffer springs. The pressure can be automatically adjusted according to the material thickness, preventing damage to thin materials while ensuring sufficient fusion pressure for thick materials, thus improving edge sealing strength by more than 20%. Simultaneously, the guide rollers on both sides of the buffer plate can position and guide the material in real time, effectively preventing deviation during transport. The edge sealing position accuracy error is controlled within ±0.5mm, significantly reducing the defect rate. Attached Figure Description

[0040] Work process: I. Preparation Phase Equipment debugging and parameter setting The operator starts the equipment via the 7-inch touchscreen (800×480 resolution) on the front right side of the main body 3 of the edge banding machine. After entering the control interface, the operator sets key parameters according to the material of the material to be edge banded (such as polyethylene film, composite film) and its thickness (0.05-0.5mm): edge banding temperature (120-250℃, accuracy ±0.5℃), pressing speed of the upper edge banding plate 9 (5-15mm / s), pressing pressure (50-200N), and conveying speed (1-3m / min). After the parameters are set, the system issues commands through the PLC (such as Siemens S7-200SMART) in the electrical control box to start the drive motor and heating module. Heating element preheating and temperature calibration The nickel-chromium alloy heating wire 13 (model Cr20Ni80, power 1.5kW) inside the heating element 8 under the edge sealing is energized and generates heat. The heat is conducted to the heating chamber 14 through the die-cast aluminum (ADC12) heating element. The built-in PT100 platinum resistance temperature sensor collects temperature data in real time and feeds it back to the temperature controller (such as Omron E5CC) to form a closed-loop control, ensuring that the heating chamber temperature is stable at the set value. The preheating process usually lasts 2-5 minutes. After the touch screen displays "Temperature Ready", the equipment enters standby mode. Mechanical component reset check A servo motor (model 110STM06030, power 600W) drives a ball screw (lead 10mm) to raise the upper sealing plate 9 along the linear guide rail (MGN15C) to the initial position (50mm from the top of the heating element); the buffer spring 16 of the sealing assembly 10 is in a free state (length 40mm), the guide pressure roller 18 remains horizontal, and the balance bar 19 extends fully out of the balance cavity 21 to ensure that there is no jamming or offset of any component. II. Material Transportation and Guiding Stage Material introduction and preliminary positioning The bag material to be sealed is conveyed to the front end of the equipment by the production line conveyor (such as a conveyor belt). The edge of the material enters the sealing station along the guide plate 14 on the rear side wall of the sealing heating body 8. The guide plate 14 is an L-shaped 304 stainless steel structure (horizontal section length 50mm), with a 1mm thick polytetrafluoroethylene coating (friction coefficient ≤0.05) on the surface, which can effectively guide the material to move in a straight line and avoid lateral deviation. Guide roller preload and straightening When the material enters below the edge-sealing assembly 10, the upper edge-sealing plate 9 moves downward by 10mm, so that the guide roller 18 contacts the material surface. The guide roller 18 is made of polyurethane (Shore hardness 85A, Φ25mm×15mm). Under the preload (approximately 30N) of the buffer spring 16, it adheres tightly to the material and moves synchronously with the material through the rotation of the bearing (608ZZ), while simultaneously correcting the edge of the material to ensure that the edge-sealing position is aligned with the heating chamber 14 (deviation ≤0.5mm). balancing mechanism synergy During the process of the guide roller contacting the material, the buffer plate 17 may tilt slightly due to uneven material thickness. At this time, the balance rod 19 (Φ11.8mm, quenched steel No. 45) at the top of the buffer plate slides axially along the balance cavity 21 (Φ12mm). The balance plate 20 (Φ20mm×3mm) restricts the radial displacement of the balance rod in the balance cavity, ensuring that the buffer plate is always in a horizontal state and avoiding uneven guide pressure that causes material wrinkles.

[0041] III. Heating and Sealing Stage The upper pressure plate presses down precisely. Once the material is positioned, the PLC issues a command, and the servo motor drives the upper sealing plate 9 to continue moving downwards at a set speed (e.g., 8 mm / s) until the top of the lower heating element 8 is in close contact with the material. At this time, the pressure applied by the plate is transmitted to the edge of the material through the heating element, and the pressure sensor (integrated in the plate) provides real-time feedback of the pressure value to ensure that the pressure remains stable within the set range (e.g., 100 N). Heating, fusion and sealing The heat generated by the heating wire 13 within the heating chamber 14 is transferred to the material edge through the heating element, causing the material to reach its melting temperature (e.g., 160℃ for polyethylene). The heating chamber is a rectangular groove (370mm × 10mm × 10mm), with mica sheets (temperature resistance ≥ 600℃) adhered to its inner wall. This concentrates heat on the material contact area, reducing heat loss (energy utilization is 35% higher than traditional devices). Under the combined action of heat and pressure, the material melts and fuses, forming a continuous sealing edge. Precise temperature and time control The heating and sealing time is set according to the material thickness (0.5-2 seconds) and strictly timed by the PLC. During this time, the temperature sensor continuously monitors the temperature of the heating element. If temperature fluctuations occur (such as exceeding the set value by 5°C), the system automatically adjusts the heating wire power to prevent the material from overheating and carbonizing or insufficient fusion. At the same time, the equipment body 11 (95% alumina ceramic, Φ20mm×30mm) ensures that the heating wire terminals are insulated (resistance ≥100MΩ) to prevent the risk of leakage. IV. Buffering and Pressing Stage Flexible edge pressing and pressure holding During the heating and fusion process, the buffer spring 16 of the edge pressing assembly 10 is further compressed as the upper pressure plate presses down (working stroke 15mm, compressed length 25mm). The silicone pad (Shore hardness 50A, 1mm thick) at the bottom of the buffer plate 17 is tightly attached to the edge of the material, applying flexible pressure (50-80N). The silicone pad can avoid material damage caused by rigid contact, while enhancing the sealing effect and preventing molten material from overflowing. Multi-component collaborative pressure holding During the pressure holding process, the upper sealing plate 9 maintains stable pressure, the guide roller 18 continues to move slightly with the material (if the conveying does not stop), and the balancing mechanism continuously maintains the level of the buffer plate. At the end of the pressure holding period, the heating wire reduces its power (e.g., to 500W) to allow the material to cool and solidify slowly under pressure, avoiding cracking of the sealing edge due to sudden cooling. V. Completion and Reset Phase The upper pressure plate rises and separates from the material. After the pressure holding time ends, the servo motor drives the upper sealing plate 9 to rise at a speed of 10mm / s. The guide pressure roller 18 leaves the material surface with the pressure plate, the buffer spring 16 gradually returns to its free state, and the balance bar 19 extends out of the balance cavity 21 under the action of the spring force. All components return to their initial positions. Edge banding material output and testing The sealed material is conveyed to the next process (such as cutting or quality inspection) by a conveyor. The quality inspection process can detect the sealing width (set to 5-10mm) and sealing performance (no bubbles or cracks) through a visual sensor. If a defective product is found, the system will alarm and record the parameters through the touch screen, which will facilitate the operator to make adjustments. Equipment Continuous Operation and Maintenance Tips The equipment repeats the above process for continuous edge sealing. When the cumulative running time reaches the set value (e.g., 200 hours), the touch screen prompts to add grease (e.g., lithium-based grease LG2) to the linear guide rail, check the heating wire resistance (normal range 5-8Ω) and the fatigue condition of the buffer spring, to ensure long-term stable operation of the equipment.
