Description

Technical Field

[0001] This utility model relates to the field of plastic film processing technology, specifically to a plastic film re-venting heat sealing device. Background Technology

[0002] In the field of plastic film processing, heat sealing technology is a crucial step, directly impacting the performance and quality of plastic film products. However, current plastic film heat sealing equipment faces a series of technical challenges. Traditional heat sealing devices often lack effective support structures due to inadequate structural design. For example, the equipment is susceptible to external vibrations during operation and lacks sufficient vibration resistance. This vibration significantly reduces the precision of the heat sealing operation, thus affecting the quality of the plastic film heat sealing. Furthermore, the lack of a perfect balancing and limiting mechanism during film heat sealing often leads to positional shifts when the film is pressed for heat sealing. This not only results in inaccurate heat sealing position but may also cause incomplete heat sealing. Problems such as over-sealing can seriously affect product quality. Furthermore, traditional heat-sealing devices often fail to effectively secure the film during the heat-sealing process. The film is prone to slipping during pressing, making precise control of the heat-sealing position difficult. Moreover, residual air between the films remains a persistent issue; traditional equipment cannot effectively remove this air, leading to defects such as bubbles or incomplete seals after heat sealing, resulting in decreased heat-sealing quality. In addition, traditional heat-sealing devices lack flexible parameter adjustment functions for plastic films of different materials, thicknesses, and types. Operators cannot easily adjust heat-sealing parameters when faced with diverse film processing needs, and can only rely on trial and error based on experience. This significantly impacts heat-sealing efficiency and quality stability.

[0003] Chinese Patent Publication No. CN207670794U discloses a heat-sealing device for plastic film re-venting, including an operating table. Columns are symmetrically arranged at one end of the top of the operating table. A heating plate is fixedly installed on one side of the top of the operating table, with a pad fitted onto the heating plate. A stop block is installed on the other side of the top of the operating table. The operating table is connected to the stop block via a sliding groove. A horizontal plate is fixedly installed at the top of the columns. A second hydraulic cylinder is installed at one end of the horizontal plate, directly above the heating plate. An upper pressure plate is installed at the bottom of the second hydraulic cylinder. A slider is installed at the other end of the horizontal plate. The horizontal plate is slidably connected to the slider via a first sliding groove. A first clamping screw penetrating the first sliding groove is installed at the top of the slider. A second hydraulic cylinder is fixedly installed at the bottom of the slider, with a venting plate at the bottom of the second hydraulic cylinder. This invention offers high heat-sealing efficiency and good results, avoids damage to the packaging bag, ensures the sealing of the packaging bag, has a simple overall structure, low cost, strong practicality, and is easy to promote.

[0004] However, this utility model has the following problems in actual use:

[0005] When the device is in use, it is prone to shaking due to external vibration or its own structural instability, which leads to a decrease in heat sealing accuracy and affects the heat sealing quality of plastic film. It lacks effective limiting and balancing measures, and the plastic film often experiences positional deviation. At the same time, the device may also tilt due to an unstable center of gravity, further compromising the stability and accuracy of the heat sealing operation. Utility Model Content

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0027] Please see Figures 1 to 4This utility model provides a plastic film re-venting heat sealing device, which is applied to the processing of plastic films. In this embodiment, the structure of the plastic film re-venting heat sealing device is improved to give it the advantages of safety and stability. Example 1:

[0028] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a plastic film re-exhaust heat sealing device, including a main body 1, a support plate 2 at the bottom of the main body 1, a control plate 3 fixedly installed on one side of the main body 1, a heat sealing knife 8 snapped into the inside of the main body 1, a power cord 9 snapped into the other side of the main body 1, a positioning plate 10 fixedly installed on the top of the support plate 2, the top of the positioning plate 10 being threadedly connected to the bottom of the main body 1, an adjusting ring 11 snapped into the outer wall of the control plate 3, and an indicator light 12 snapped into the outer wall of the control plate 3. Therefore, power is provided to the heat sealing knife 8 through the power cord 9. This connection method ensures a stable energy supply for the heat sealing knife 8 during heat sealing operations. A stable power supply is crucial for the normal operation of the heat sealing knife 8, enabling it to efficiently and stably heat seal the plastic film. This improves the overall efficiency and quality of the heat sealing device. The positioning plate 10 ensures the secure installation of the main body 1 on the support plate 2. During device operation, regardless of external vibration or interference, the design of the adjusting ring 11 allows operators to easily adjust the parameters of the heat sealing device. Since different types and thicknesses of plastic films have different requirements for heat sealing parameters, operators can precisely change the parameters by rotating the adjusting ring 11 to meet the heat sealing needs. At the same time, the indicator light 12 can clearly show the operator the working status of the device, including the power connection status and whether the device is operating normally. Operators can understand the device status in a timely manner according to the indication of the indicator light 12, thereby more effectively controlling the heat sealing process and improving heat sealing efficiency and quality. Example 2:

[0029] Please see Figures 1 to 3 To facilitate manual adjustment and ensure greater convenience during heat sealing, a device adapter block 4, a pressing plate 5, and a support plate 6 are provided.

[0030] The top of the main body 1 is threadedly connected to an adapter block 4. A pressing plate 5 is snapped into the inside of the adapter block 4. A support plate 6 is provided on the top of the pressing plate 5. A support rod 13 is threadedly connected to the inside of the adapter block 4. Limiting rings 14 are snapped into both sides of the support rod 13. The inside of the pressing plate 5 is threadedly connected to the outer wall of the support rod 13. Rubber plates 15 are snapped into both sides of the pressing plate 5. A soft rubber sheet 16 is snapped into the top of the support plate 6. A threaded rod 17 is welded to the bottom of the support plate 6. The bottom of the threaded rod 17 is threadedly connected to the top of the pressing plate 5. Therefore, by pressing the plate 5... The vertical position can be flexibly adjusted by the support rod 13. The presence of the limiting ring 14 ensures the stability of the support rod 13 during use, thereby ensuring the accuracy and stability of the position of the pressing plate 5. This provides a strong guarantee for the subsequent accurate pressing and heat sealing operation of the plastic film. During the heat sealing operation, the rubber plate 15 facilitates manual support and ensures that the hand can find the point of force application. When the operator manually adjusts the support plate 6, the pressing plate 5 will move in tandem, which increases the friction between the soft rubber sheet 16 and the hand. Example 3:

[0031] Please see Figure 4 In order to ensure that the plastic films can be smoothly connected and to prevent positional deviation, a balance plate 7 is installed.

[0032] A balance plate 7 is inserted into the outer wall of the main body 1. A fixing plate 18 is welded to the bottom of the balance plate 7. A bolt 19 is threadedly connected to one side of the fixing plate 18. The bolt 19 passes through the inside of the fixing plate 18 and is threadedly connected to the outer wall of the main body 1. Therefore, the fixing plate 18 and the bolt 19 are designed to facilitate the inward pushing of the plastic film and ensure the stable installation of the balance plate 7 on the main body 1. When the plastic film is pressed and heat-sealed, the balance plate 7 plays an important balancing role. It can balance the weight distribution of the device and effectively avoid tilting due to the instability of the device's center of gravity.

[0033] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0034] In this invention, the working steps of the device are as follows:

[0035] First, place the plastic film re-venting heat sealing device in a suitable working position, ensuring that the support plate 2 is placed stably. The support plate 2 is connected to the bottom of the main body 1 by the positioning plate 10 on its top, providing stable support for the entire device. Check the status of the indicator light 12 on the control board 3 to confirm that the device power supply is normal. Observe the indicator light 12 to determine whether the device is in a working state. According to the type and thickness of the plastic film to be heat sealed, rotate the adjusting ring 11 that is snapped on the outer wall of the control board 3 to adjust the parameters of the heat sealing device to meet the film heat sealing requirements. Place the plastic film in the heat sealing area, above the heat sealing knife 8 that is snapped inside the main body 1. When the heat sealing operation is started, the pressing plate 5 is pressed down with the cooperation of the adapter block 4, the support rod 13 and the limiting ring 14.
