[0029] In order to make the purpose, technical scheme and advantages of the embodiments of the present disclosure more clear and clear, the embodiments of the present disclosure are further described in detail below in conjunction with the drawings, and the schematic embodiments and their descriptions of the embodiments of the present disclosure are only used to explain the embodiments of the present disclosure, and not as a limitation on the embodiments of the present disclosure.

[0030] As Figure 1 Indicated, a heat sealing and hot cutting device of the garbage bag of the application includes heat sealing knife 1, hot cutting knife 2, shrinkage guide wheel 3, folding forming plate 4 and conveying track 5.Each component cooperates to ensure that the equipment effectively avoids secondary pollution and improves material utilization rate during the processing process.

[0031] Heat sealing knife 1 is mainly used for applying heat and pressure to specific positions of the garbage bag to complete heat sealing operation, ensuring that the bag opening is tightly fitted and firm.A layer of anti-sticking coating composed of fluoropolymer is sprayed on the front surface of heat sealing knife 1, so that residual materials are not easy to adhere to it.This structure not only reduces cleaning and maintenance cost, but also effectively maintains the cleanliness of the working interface.When actual packaging is carried out, for example, the packaging process of flat bag of PE material, it can ensure that the edge has no excess residue accumulation.

[0032] The hot cutting knife 2 is arranged in the adjacent area with the hot sealing knife 1 mentioned above, and the two are arranged in synchronization to ensure synchronous operation. It completes the cutting process by high-speed rotation or movement of the blade surface to contact the preheated part, so as to accurately cut off the waste part according to the set parameters, which is beneficial to recycling. For small and compact garbage bags made of multi-layer composite environment-friendly materials, synchronous sealing and cutting actions are performed at the same position to ensure size consistency and quality stability, and to simplify the subsequent process flow design.

[0033] The shrinkage guide wheel 3 is located on the transmission line before the hot sealing and cutting assembly. The main body of the component is supported by a metal wheel frame and an elastic roller, and is equipped with a tension adjusting mechanism to realize stable stretching during the feeding process of the untreated product, and to ensure that the product is complete and regular in shape when entering the processing area. In particular, two groups of adjustable spacing baffle type limiting devices are installed at this position to minimize the deviation of the direction angle, and can normally function when facing garbage packaging materials with different thicknesses or wide size changes, such as the application example of the raw material unfolding and straightening of large and medium-sized garbage bags, which proves its effectiveness, feasibility and high reliability.

[0034] The folding forming plate 4 is arranged immediately after the hot sealing and cutting operation, and is used to give necessary guidance and help shaping during the product discharge stage, that is, the single object processed by editing is bent and stacked in order along the set track by relying on the curvature characteristics of its own shape. For some ultra-thin plastic handbags made of materials with easy-to-break films, they need to rely on such molds to standardize folding and prevent wrinkles and deformation damage, so as to ensure the smooth operation of subsequent operations such as stacking, storage and transportation without being affected.

[0035] The conveying track 5 connects all functional components and has obvious bridging and linking effects; on the one hand, it provides a physical bearing surface to meet the smooth flow and transfer requirements of the processed goods along the designated point line, and on the other hand, it has a built-in transmission power conduction system to drive other subordinate accessories to create efficient working conditions. It is worth noting that the shrinkage guide wheel 3 is additionally equipped with an independently working boundary cleaning component to regularly clean the adhered impurities, prevent system failure and blockage, improve the service life, enhance the endurance performance, prolong the overall operation life, and reduce energy consumption and expenses.

[0036] In addition, it is supplemented that the bottom of the conveying channel is paved with a material with electrostatic shielding properties, which effectively blocks the charge induction effect of air dust particles and minimizes the occurrence of unnecessary dirt accumulation problems to the lowest level to ensure environmental friendliness and clean production targets.

[0037] In one embodiment, further as Figure 2As shown, the heat sealing knife 1 of the heat sealing and cutting device for garbage bags of the present application is also equipped with a heating element 6 embedded in the interior of the heat sealing knife 1. The heating element 6 can be temperature-adjusted according to the specific properties of the actual processing material, ensuring that different materials can achieve efficient sealing effect at appropriate temperature. Through this flexible temperature control mechanism, not only the sealing quality of the material is improved, but also the secondary pollution and material waste caused by poor sealing are fundamentally reduced.

[0038] For example, in actual operation, when processing different types and thicknesses of plastic materials, the heating element 6 can be set to different target temperatures by the built-in controller. For relatively thin and tough polyethylene film materials, a lower working temperature can meet the requirements, while for composite materials with larger thickness, the working temperature of the heating element 6 is appropriately increased. In order to ensure accurate temperature control, the heating element 6 is usually located in the key working area of the heat sealing knife 1, closely contacts the heat sealing part and is uniformly distributed, ensuring that heat is uniformly transmitted to the area to be sealed.

[0039] Specifically, the heating element 6 adopts an electric heating form and is installed in the heat sealing knife 1 body by winding or planar embedding. In order to optimize the structural design and ensure good heating effect and durability, the heating element 6 is made of high-performance alloy material and works together with an insulating protective layer. Temperature control sensors are arranged around the heating element 6 to realize real-time temperature monitoring, thereby further improving the stability and response speed of the system. This design not only ensures that the heat sealing knife 1 can reach the required temperature in a short time, but also has excellent heat dissipation performance and stability for long-time work. Thus, the goal of accurately controlling the temperature according to the material properties is fully achieved technically.

[0040] In one embodiment, the heat sealing knife 1 of the heat sealing and cutting device for garbage bags of the present application is further provided with a cooling device 7. The cooling device 7 is installed at the rear of the heat sealing knife 1, close to the heating element 6. Through this installation position, the cooling device 7 can immediately cool the sealing part after the heat sealing operation is completed. This design avoids the problem of re-sticking of the sealing part due to the failure of the temperature to drop rapidly, reduces the waste sticking situation, and ensures that the heat-sealed product has stable structure and quality. Specifically, the cooling device 7 includes but is not limited to a group of heat dissipation fans, cold air ducts or liquid cooling modules, which can effectively absorb and dissipate heat.

[0041] The cooling device 7 is designed to closely cooperate with the heat sealing knife 1, so that the sealing part is quickly cooled without affecting the operation of other components. For example, the cooling device 7 can be composed of a number of small and closely arranged heat dissipation fins, which are directly fixed on the back of the heating element 6. This not only ensures sufficient cooling efficiency, but also facilitates installation and maintenance, without occupying too much space or interfering with the normal heat sealing process.

[0042] The cooling device 7 can be directly connected to the inside of the frame of the heat sealing knife 1 through an embedded installation method. This way not only saves the equipment volume, but also ensures excellent heat exchange effect between the cooling device 7 and the heating element 6. In addition, the working principle of the cooling device 7 can be based on a forced air cooling system, that is, by using a high-efficiency air blower to continuously blow low-temperature air from the outside to the just-heated garbage bag sealing, so that it is quickly solidified and formed; or based on a circulating cold water system, which uses the high specific heat capacity of liquid to absorb heat and lead it out of the device for cooling. By reasonably selecting and integrating the cooling scheme, the efficiency and yield of the entire garbage bag production system can be significantly improved.

[0043] In one embodiment, an important feature of the heat sealing and hot cutting device of the garbage bag of the present application is that the hot cutting knife 2 is connected to the heat sealing knife 1 through an elastic support 8. Specifically, the elastic support 8 suspends the hot cutting knife 2 on the heat sealing knife 1, providing flexible and precise spatial adjustment between the two. Such a design ensures that the relative positions of the two can be maintained stable and aligned under any conditions during heat sealing and cutting operations. Avoiding cutting deviation or insufficient precision caused by equipment aging, external vibration and other unexpected factors, effectively reducing the generation of irregular waste, and optimizing the geometry of the waste to ensure that it is more convenient for subsequent classification and collection in the recycling process.

[0044] In addition, the use of the elastic support 8 can also absorb a certain range of operation deviations and error accumulation, so that the device still maintains good performance even after a long time of operation. The design of the elastic support 8 also improves the overall fault tolerance of the system and enhances the adaptability to complex environmental changes.

[0045] Specifically, the elastic support 8 can be firmly fixed to the frame of the heat sealing knife 1 during installation, while leaving enough expansion space so that the hot cutting knife 2 can move moderately according to actual needs without deviating from the established working path. For example, the elastic support 8 is made of spring or other materials with good elasticity, and the structure is designed to ensure the durability and reliability of these components, ensuring the accuracy and smoothness of long-term use. During the assembly and debugging stage, the most suitable working gap and elastic limit can be determined through test calibration.

[0046] In one embodiment, the front end of the hot cutting knife 2 of the heat sealing and hot cutting device of a garbage bag of the present application is provided with a waste collection groove 9 for collecting waste residues generated during the cutting process. This design not only reduces the pollution caused by waste to the environment, but also makes waste more efficient for centralized treatment, facilitating subsequent recycling or disposal procedures. By introducing this component, the efficiency of the entire system is significantly improved, and unnecessary waste scattering in the working environment is effectively avoided, ensuring the cleanliness and order of the production workshop. In addition, the hot cutting knife 2 is adjacent to the heat sealing knife 1, ensuring that the heat-sealed garbage bag can be immediately and accurately cut, thereby providing the necessary conditions for immediate cleaning of waste. The waste collection groove 9 is closely connected to the hot cutting knife 2, which can maximize the interception of waste without affecting the cutting accuracy.

[0047] For example, the front end of the hot cutting knife 2 is provided with a waste collection groove 9, which can be achieved by mechanical fixation or integrated design. Specifically, the entrance of the waste collection groove 9 is located directly in front of the hot cutting knife 2 and has a width that matches the cutting area, ensuring that all debris, short edges or other small parts generated at the moment of cutting can enter smoothly. The inside of the collection groove 9 has an inclined angle design to guide the waste to fall smoothly into the bottom of the collection device. The collection groove 9 can be fixed to the front end of the hot cutting knife 2 by bolts or buckles, which is easy to disassemble, clean and replace to adapt to different job requirements. At the same time, such a structure also supports the easy and quick emptying of the full waste groove without disassembling other components, maintaining the long-term stable operation of the equipment.

[0048] In one embodiment, continuing to refer to Figure 2 , the shrinkage guide wheel 3 of the heat sealing and hot cutting device of a garbage bag of the present application includes at least one pair of auxiliary tension adjusting wheels 10, which are located on both sides of the shrinkage guide wheel 3 to adjust the tension and flatness of the garbage bag during transportation. By accurately adjusting the relative position and distance of the pair of auxiliary tension adjusting wheels 10, it is ensured that the garbage bag can always maintain appropriate tension during transmission, effectively reducing wrinkles caused by tension fluctuations. This device further improves the effect of subsequent heat sealing and cutting processes, ensuring consistent and attractive heat sealing lines and cleaner cutting edges.

[0049] The structure of the auxiliary tension adjusting wheels 10 allows for fine tuning according to specific needs, such as manual adjustment screws or automatic control systems, which monitor the transmission status of the garbage bag in real time and make corresponding adjustments. These adjusting wheels not only adapt to garbage bags of different thicknesses and material properties, but also optimize tension distribution to improve the consistency and stability of the entire production process.

[0050] For example, in a specific implementation, the pair of auxiliary tension adjustment wheels 10 can be installed on the left and right sides of the shrink guiding wheel 3, and exert moderate pressure on both sides of the garbage bag through spring devices or other forms of elastic mechanisms, to ensure that the garbage bag passes through the heat sealing and cutting station smoothly without deviation or accumulation. This structural optimization not only improves the reliability of the equipment operation, but also greatly reduces the failure rate and maintenance cost. At the same time, the spacing between these tension adjustment wheels can be flexibly set according to the actual processing situation, to ensure that it is suitable for garbage bags of various specifications and sizes.

[0051] In one embodiment, the shrink guiding wheel 3 of the heat sealing and cutting device for garbage bags of the present application is equipped with an additional designed scraper 11 device. This unique design not only can clean the surface of the guiding wheel in real time, ensuring the continuous and efficient operation of the equipment, but also effectively prolongs the service life of the device. In terms of structure, the scraper 11 is tightly installed at the edge of the shrink guiding wheel 3 and is parallel to the rotating axis of the wheel. The scraper 11 is made of flexible material and realizes the contact and cleaning function without affecting the normal rotation of the wheel body. The scraper 11 is stably connected to the peripheral bracket of the shrink guiding wheel 3 through a fixing part, and can be flexibly adjusted in position during the working process to ensure the optimal cleaning effect. This automatic cleaning design avoids the situation that impurities accumulate and affect the production efficiency due to long-term use.

[0052] Specifically, the shrink guiding wheel 3 and its matched scraper 11 adopt a modular assembly method. During assembly, the scraper 11 with specific mounting holes or sliding grooves is first pre-installed near the periphery of the guiding wheel; and then it is fastened to the frame structure by using bolts, clasp springs and other accessories. Since the scraper 11 is at the outer edge and close to the surface of the guiding wheel, the slight centrifugal force generated during the movement of the guiding wheel with the material will cause any residual objects attached to it to be scraped off and fall into the bottom dust collection facility. For example, through such technical means, the surface of the guiding wheel can be kept clean and smooth at all times, whether in high-speed operation or low-speed running state, thereby improving the stability of tension control during the processing process and the consistency and aesthetic degree of the finished product.

[0053] In summary, the cooperation of each component in the above-mentioned device ensures high precision and high efficiency of garbage bag processing, and also enhances the durability and reliability of the overall equipment. It is particularly worth noting that the paired setting of the scraper 11 and the shrink guiding wheel 3 greatly promotes the automation level of the system and reduces the cost caused by downtime maintenance.

[0054] In one embodiment, as shown in Figure 4 , the folding forming plate 4 of the heat sealing and cutting device for garbage bags of the present application is equipped with a guide roller 12 (see Figure 2), located at both ends of the arc. The primary function of these guide rollers 12 is to assist the garbage bag in maintaining a smooth folding process, reducing frictional resistance and material loss. The specific arrangement ensures that the garbage bag is supported by the guide rollers 12 before entering and leaving the plate surface, ensuring a smooth and stable folding process. This structure not only helps to improve the quality of the finished product, but also further optimizes the overall efficiency of the device. In order to ensure that the folding process is wrinkle-free and smooth, the arc design is specially considered to minimize the contact area with the surface of the garbage bag, reducing the risk of material adhesion and damage caused by friction. In addition, this design reduces the amount of surface residue, which is beneficial for material reuse after waste treatment.

[0055] The technical implementation of the guide rollers 12 involves installing one or several pairs of rollers in the form of rolling bearings at both ends of the folding forming plate 4. Specifically, the distance between each pair of guide rollers 12 is carefully adjusted to provide sufficient guidance without causing excessive compression of the garbage bag material. For example, the rollers are made of lightweight alloy materials with good wear resistance and low friction coefficient, and are further lubricated on their surfaces to further reduce friction loss. To ensure stability and durability, the rollers are connected to fixed supports after precision machining, and the supports are firmly attached to the edge positions of the folding forming plate 4. Such configuration not only supports the smooth movement of the garbage bag on the arc surface, but also increases the safety and reliability of the device as a whole.

[0056] In one embodiment, the heat sealing and cutting device for garbage bags of the present application is characterized in that the folding forming plate 4 is provided with an internal blowing pipe 13. The pipe applies a gas flow from the inside to the garbage bag, effectively assisting in unfolding the garbage bag and reducing wrinkles. This design significantly improves packaging quality without affecting the overall layout of the device, ensuring smooth and dimensionally stable finished product surfaces. Specifically, the internal blowing pipe 13 cleverly integrates a gas supply interface and evenly distributed small holes, which, by properly configuring these components, provide a stable air flow to the inside of the garbage bag at the appropriate time point to prevent wrinkles caused by material properties or during transmission.

[0057] The built-in blowing pipe 13 is arranged in close cooperation with the folding forming plate 4, installed in the internal structure thereof, and both are kept relatively stable through fixed connection, ensuring that the gas can be accurately delivered from the specific area of the folding forming plate 4 to the inner cavity of the garbage bag. For example, before the folding forming operation is started, the system will first start the blowing function, guide the gas into the bag body through the preset path in the folding forming plate 4, make it naturally expand and flatten the possible tiny wrinkles, and ensure the smooth progress of the subsequent process. At the same time, in order to realize this function, the coordinated work of the control system is needed, that is, the blowing action needs to be strictly synchronized with the folding action, and the gas flow and duration are adjusted to adapt to the needs of garbage bags of different specifications and material types. In this way, not only the appearance quality of the finished garbage bag is optimized, but also the production efficiency of the entire device is improved.

[0058] In one embodiment, the conveying track 5 of the heat sealing and cutting device of a garbage bag of the present application adopts a modular design 14, and each part is detachable. Such a modular design 14 not only simplifies the assembly and maintenance process, but also enables each component to be conveniently and quickly disassembled and cleaned when necessary. In particular, since there may be a problem of residue accumulation during the manufacturing process of the garbage bag, the modular design 14 can effectively avoid equipment blockage caused by residues, ensure the smooth operation of the production line, and improve work efficiency. In addition, such a modular structure allows the configuration and length of the conveying track 5 to be flexibly adjusted according to production needs, further optimizing the entire process flow. Specifically, the conveying track 5 runs through each component in the connecting device, i.e., the heat sealing knife 1, the heat cutting knife 2, the shrinkage guide wheel 3, and the folding forming plate 4, and carries and guides the garbage bag to pass through each processing position continuously and smoothly. In order to facilitate disassembly and installation, buckles or quick lock screws are usually used to fix the interfaces between the modular components.

[0059] For example, in one embodiment, the conveying track 5 can be constructed by selecting standard module units that are easy to disassemble, and these modules are firmly and tightly combined together through quick connectors. Each module unit can be independently disassembled and replaced, thereby realizing convenient and efficient maintenance and cleaning operations, and ensuring that the normal production process is not affected. At the same time, in order to prevent the occurrence of secondary pollution problems, the modular design 14 also includes the application of smooth materials on the contact surface and the setting of anti-static materials at the bottom. In this way, while meeting the cleaning needs, the mutual influence between the environment and the production materials can also be reduced.

[0060] In one embodiment, referring to Figure 3The conveying track 5 of the heat sealing and cutting device for garbage bags of the present application is provided with a set of automatic induction dust removal system 15, which can automatically clean the track surface after each transmission to prevent secondary pollution. The dust removal system is located on one side of the conveying track 5 and closely cooperates with it to ensure that it does not affect normal transmission during operation. The structure of the automatic induction dust removal system 15 includes a group of sensors and actuators, which can accurately sense the state of the track surface and start cleaning operation when needed.

[0061] Specifically, the automatic induction dust removal system 15 monitors the surface of the conveying track 5 in real time through sensors. These sensors may include photoelectric or pressure sensing technology to detect the presence of foreign matter. Once the risk of contamination is determined, the execution part of the dust removal system will quickly start to remove surface debris using air jet or other physical methods. In addition, the dust removal system also integrates an intelligent control module that can cooperate with the control system of the entire device to ensure the safety and efficient operation of the equipment.

[0062] For example, the cleaning strength can be adjusted by installing adjustable angle blow nozzles or brushes to ensure that the contaminants can be effectively removed without damaging the track surface. By reasonably arranging the positions of the components and optimizing the connection method, the system not only ensures good cleaning effect, but also improves the overall work efficiency.

[0063] In one embodiment, the conveying track 5 of the heat sealing and cutting device for garbage bags of the present application is provided with an anti-static mat 16 at the bottom, which has good elasticity and anti-static performance. This design effectively reduces dust adsorption and maintains the cleanliness of the production environment. The anti-static mat 16 is installed at the bottom of the conveying track 5, which provides an additional static electricity dissipation path without affecting the conveying efficiency, preventing the potential impact of static electricity accumulation on equipment and products.

[0064] Specifically, the anti-static mat 16 is made of high-elasticity material, which ensures that it can closely fit the curved and flat areas at the bottom of the conveying track 5. In order to ensure excellent anti-static performance, conductive carbon black filled or ionic conductive polymer is selected as the material, which can quickly release the generated static electricity to the ground. The anti-static mat 16 is connected to the conveying track 5 by adhesion, embedding or magnetic attraction, and according to the specific installation environment, the appropriate fixing method can be selected to ensure that the anti-static mat 16 will not fall off or displace due to mechanical vibration or temperature change.

[0065] In practical applications, the anti-static mat 16 is not limited to the installation position at the bottom of the conveying track 5, but can also be applied to the surface of the conveying chain, the guide wheel or other components that need to have anti-static function. For example, when using an anti-static brush to clean the dust attached to the garbage bag during the manufacturing process, it can be connected to the conveying track 5 through a matching grounding circuit to form a complete anti-static system, thereby better playing the overall protection role. In addition, the application of the mat also covers various working conditions, and can maintain long-term stable performance in dry, humid and dusty complex environments.

[0066] In actual operation, when the device is in use, the garbage bag is first introduced into the shrink guide wheel 3, where it is controlled by tension and accurately positioned, and is assisted to unfold to ensure that it remains flat and wrinkle-free during transmission. Subsequently, the garbage bag enters the position of the heat sealing knife 1, where the heat sealing knife 1 applies heat and pressure to complete the sealing, and the anti-sticking coating at the front end prevents residual material from sticking, reducing secondary pollution and improving material utilization. Next, the garbage bag reaches the hot cutting knife 2, where it is precisely cut off to ensure that the waste is neat for subsequent recycling. Then, with the help of the folding forming plate 4, the garbage bag that has been sealed and cut is quickly folded and formed, and its unique arc design reduces the contact area, reduces friction and reduces surface residual material, which is beneficial to material recycling. Throughout the process, the conveying track 5 connects each component throughout, carries and guides the garbage bag to pass through each station smoothly, ensuring smooth flow. At the same time, the automatic cleaning frame structure on the shrink guide wheel 3 continuously cleans the attached material to prevent blockage, enhancing the durability and cleanliness of the equipment. The anti-static material at the bottom of the conveying track 5 can effectively prevent secondary pollution caused by dust adsorption.
