Description

Technical Field

[0001] This utility model relates to the field of edge sealing machine technology, specifically an edge sealing machine for processing plastic bags. Background Technology

[0002] An edge banding machine is a woodworking device specifically designed for edge treatment of wooden products such as furniture and cabinets. Its main function is to firmly adhere preheated edge banding tape to the cut edges of boards to prevent the edges from swelling and cracking due to moisture. It also enhances the appearance, prevents scratches, and increases durability. Edge banding machines are relatively simple to operate and highly efficient, and are widely used in furniture manufacturing, decoration, and other industries. They are an indispensable tool in modern woodworking production.

[0003] A sealing machine for plastic bags is a specialized piece of equipment used for heat-sealing the edges of plastic films. It is a key piece of equipment in the production of various plastic bags (such as food bags, shopping bags, garbage bags, etc.). During operation, the machine applies heat and pressure to the edges of the plastic film through heated sealing molds or rollers, causing the film to melt and firmly adhere together to form a sealed edge. This type of sealing machine is typically highly efficient and automated, ensuring a smooth, firm, and airtight seal. It can also adjust the temperature, pressure, and speed according to the thickness and material of the plastic film, making it an indispensable part of the plastic flexible packaging production line.

[0004] However, existing sealing machines for plastic bag processing, especially those with traditional fixed connections, make it difficult to accurately set and reproduce the required sealing width. Furthermore, the adjusted spacing between the hot rollers can change slightly during operation or when subjected to vibration, resulting in inconsistent sealing widths and affecting product quality. Additionally, uneven force distribution can easily cause bags to shift, jam, or even break. Moreover, the adjustment process is unstable, making it difficult to achieve the desired sealing effect. To address these issues, a new sealing machine for plastic bag processing is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a sealing machine for processing plastic bags, which solves the problems in the prior art of not being able to accurately and stably adjust the spacing of the hot rolling rollers and not being able to ensure the stability of the adjustment and transportation processes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sealing machine for processing plastic bags, comprising a processing platform, a bearing frame fixedly connected to the top center of the processing platform, fixed plates fixedly connected to both ends of the top of the bearing frame, a drive roller rotatably connected through one side of the fixed plates, a worm gear fixedly connected to one end of the drive roller, a transmission rod rotatably connected through one side of the fixed plate, a worm fixedly connected to one end of the transmission rod and meshing with the worm gear, a rocker arm slidably connected through the other end of the transmission rod, uniformly distributed sliders slidably connected through the top of the bearing frame, connecting blocks fixedly connected to the top of each slider, sliding rods slidably connected through one end of each connecting block and slidably connected to the fixed plates, rotating rods rotatably connected through the bearing frames, a first gear fixedly connected to one end of each rotating rod, a transmission assembly provided at the bottom of the sliders, and a disassembly assembly provided on one side of the top of the processing platform.

The limit rod is slidably connected to the fixed rod, and a bearing roller is provided between the fixed blocks.

[0013] By adopting the above technical solution, the installed support rod can support and fix the required first spring, thereby driving the limiting rod to slide within the support rod, thus fixing and limiting the fixed block.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0033] Reference Figure 1 and Figure 2 This utility model discloses a sealing machine for plastic bag processing, including a processing platform 1. The processing platform 1 can support the required equipment. A support frame 2 is fixedly connected to the top center of the processing platform 1. The support frame 2 can support and fix the required components and structures. A servo motor at one end drives a first gear 15, which in turn drives a second gear 16, causing a rotating rod 14 to rotate on the support frame 2. Fixed plates 3 are fixedly connected to both ends of the top of the support frame 2. The fixed plates 3 can support and fix the required components and structures. A rocker arm 8 is slidably connected to the other end of a transmission rod 6, allowing the transmission rod 6 to rotate on the fixed plate 3. Hot rollers 17 are slidably connected to both ends of the outer ring of the rotating rod 14, and the hot rollers 17 are in contact with a connecting rod 12. The hot rollers 17 can seal the required raw materials. The disassembly component includes a support plate 19, which is fixedly connected to one side of the processing platform 1 and slidably connected to a slide plate 13. The support plate 19 can support the required components and structures, and the support plate 19 has a feed port to transport the raw materials. The support rollers 25 are arranged between the fixed blocks 20. The support rollers 25 can carry the required raw materials. A connecting frame 26 is fixedly connected to the top side of the processing platform 1. The connecting frame 26 can support the required components and structures. A push rod motor 30 is fixedly connected to the top of the connecting frame 26. The push rod motor 30 can move the cutter 31 closer to or further away from the raw materials. The output end of the push rod motor 30 passes through the connecting frame 26 and is equipped with the cutter 31. The cutter 31 can cut the required raw materials. A hot pressing assembly 32 is arranged on the middle side of the top of the processing platform 1. The hot pressing assembly 32, including the fixed frame, supports another servo motor, which drives the transmission roller to transport the raw materials. At the same time, there are evenly distributed transport blocks on the transmission roller, and a hot pressing plate is also arranged on the transmission roller, so that the bottom edge of the raw materials sealed on both sides can be sealed, thereby producing the required plastic bags.

[0034] Reference Figure 2 and Figure 4 A drive roller 4 is rotatably connected through one side of the fixed plates 3. A worm gear 5 is fixedly connected to one end of the drive roller 4. A transmission rod 6 is rotatably connected through one side of the fixed plates 3. A worm 7 is fixedly connected to one end of the transmission rod 6, and the worm 7 meshes with the worm gear 5. A uniformly distributed slider 9 is slidably connected through the top of the bearing frame 2. A connecting block 10 is fixedly connected to the top of each slider 9. A uniformly distributed slide rod 11 is slidably connected to one end of each connecting block 10, and the slide rod 11 is slidably connected to the fixed plate 3. By rotating the transmission rod 6, the worm gear 5 is driven by the worm 7 to rotate on the fixed plate 3, thereby causing the drive roller 4 to drive the connecting block 10 to slide on the bearing frame 2, and thus the connecting block 10 to drive the slider 9 to slide on the bearing frame 2. This allows for precise and progressive adjustment of the spacing of the hot rolling rolls 17. A uniformly distributed rotating rod 14 is rotatably connected through the bearing frames 2. A first gear 15 is fixedly connected to one end of the top rotating rod 14. A transmission assembly is provided at the bottom of the slider 9. The processing platform 1 has a disassembly assembly on one side of its top. The transmission assembly includes a connecting rod 12, which is fixedly connected to the bottom ends of the slider 9. A transport roller 18 is slidably connected through the middle of the outer ring of the top hot roller 17 and contacts the connecting rod 12. Slide plates 13 are provided at both ends of the hot rollers 17. A second gear 16 is fixedly connected to one end of the bottom rotating rod 14 and meshes with the first gear 15. The sliding of the slider 9 drives the top hot roller 17 to slide. Then, driven by the slide plates 13, the bottom hot roller 17 slides synchronously. Then, through the transmission between the first gear 15 and the second gear 16, the rotating rod 14 drives the hot roller 17 to rotate. Then, another transport roller 18 provided on the bottom rotating rod 14 ensures stable transport of the raw materials, thereby providing a smoother and more uniform conveying force, reducing the shaking and wrinkling of the plastic bag raw materials during the transport process, and creating better conditions for subsequent precise sealing.

[0035] Reference Figure 2 and Figure 3A fixed block 20 is slidably connected to both ends of one side of the support plate 19. A fixed rod 21 is slidably connected to one end of each fixed block 20, and the fixed rod 21 is slidably connected to the support plate 19. A support rod 22 is slidably connected to one end of each fixed rod 21. A first spring 23 is evenly distributed inside the support rod 22. A limit rod 24 is fixedly connected to one end of each first spring 23, and the limit rod 24 is slidably connected to the support rod 22. The limit rod 24 is slidably connected to the fixed rod 21. By allowing the limit rod 24 to slide into the support rod 22, the first spring 23 is compressed, causing the support rod 22 to slide out of the fixed rod 21, thus allowing the fixed rod 22 to slide out of the support plate 19. Rod 21 slides out of the support plate 19 and the fixing block 20, thereby allowing the fixing block 20 to slide out of the support plate 19, which reduces the complex steps in the disassembly and installation process and lowers the difficulty of operation. Both ends of the connecting frame 26 are connected to the support rod 27 through and fixedly. The bottom of the outer ring of the support rod 27 is fitted with a second spring 28. The middle of the outer ring of the support rod 27 is connected to the pressure block 29 through and slidably. The pressure block 29 is slidably connected to the connecting frame 26 and contacts the cutter 31. Through the squeezing of the cutter 31, the pressure block 29 slides on the connecting frame 26 and the support rod 27, thereby squeezing the second spring 28, which helps the cutter 31 to cut into and cut the material more smoothly.

[0036] Working principle: The fixed block 20 slides into the bearing plate 19, then the fixed rod 21 slides into the bearing plate 19 and passes through the fixed block 20. Next, the limiting rod 24 slides into the support rod 22, thus compressing the first spring 23, causing the support rod 22 to slide into the fixed rod 21. Then, due to the rebound of the first spring 23, the limiting rod 24 slides out of the support rod 22 and into the fixed rod 21, thus fixing and limiting the required fixed block 20. Then, the rotation of the transmission rod 6 causes the worm gear 7 to rotate on the fixed plate 3. Then, through the meshing connection between the worm gear 7 and the worm wheel 5, the worm wheel 5 drives the drive roller 4 to rotate between the fixed plates 3. Then, through the first groove on the drive roller 4 and the first cylinder on the connecting block 10, the connecting block 10 is driven to slide on the sliding rod 11, thus causing the connecting block 10 to drive the slider 9 to slide on the bearing frame 2. Finally, through the connecting rod 12... The second cylinder on the top drives the top hot rolling roller 17 and the transport roller 18 to slide on the top rotating rod 14. Then, through the second groove at one end of the hot rolling roller 17 and the third cylinder at one end of the slide plate 13, the slide plate 13 drives the bottom hot rolling roller 17 to slide on the bottom rotating rod 14. Then, through the first gear 15 driven by the servo motor, and through the meshing connection between the first gear 15 and the second gear 16, the top and bottom rotating rods 14 rotate. Then, through the third groove on the rotating rod 14 and the limiting block on the hot rolling roller 17, the rotating rod 14 drives the hot rolling roller 17 to rotate. Then, through the contact and compression of the pressure block 29 by the cutter 31, the pressure block 29 slides on the connecting frame 26, and then slides on the bearing rod 27, thereby compressing the second spring 28. Then, through the rebound of the second spring 28, the pressure block 29 provides a certain buffer for the cutter 31.
