[0002] In automated filling technology, after filling high-viscosity materials (such as asphalt) into packaging bags, the bag opening needs to be sealed to prevent leakage. This filling method involves the following steps: First, the material is filled into the packaging bag; once a certain weight or capacity is reached, filling is stopped; then, the bag opening is sealed using heat or glue; finally, the filled and sealed bag is cut from the entire long packaging bag. This method has the following disadvantages: 1. The need to stop filling during sealing significantly reduces packaging efficiency; 2. Heat sealing consumes a large amount of energy, while using glue requires applying it to the bag opening first, greatly increasing material input and processing time. Summary of the Invention

[0008] Furthermore, the specific content of step S1 is as follows: the packaging bag is placed on the feeding port of the canning device, and after a certain amount is filled, the opening of the packaging bag is sealed by the sealing device.

[0009] As a preferred embodiment, the sealing device is equipped with a cooling device for cooling the seal of the packaging bag.

[0010] Furthermore, in step S2, when cutting the seal, the seal is cut into upper and lower parts. The lower part is the upper seal of the next packaging bag, and the upper part is the lower seal of the previous packaging bag.

[0011] As a preferred embodiment, step S3 specifically involves placing the cooling pool below the packaging bag.

[0012] Furthermore, the packaging bag is a long packaging bag used to package multiple packaging bags.

[0015] As a preferred embodiment, the cooling device is located on the sealing device. When the sealing device presses the packaging bag to seal, the cooling device cools the material inside the seal, causing the material to adhere to the packaging bag seal and thus achieve encapsulation.

[0016] As a preferred embodiment, the cooling device is a cooling pool, in which the packaging bag falls and cools the material inside the seal.

[0017] As a preferred embodiment, the sealing device includes a frame, a pressing block mounted on the frame for pressing the opening of the packaging bag, and a driving device for driving the pressing block to move.

[0018] As a preferred embodiment, the cutting device includes a cutter that cuts the seal of the packaging bag by driving the movement of the cutter.

[0019] As a preferred embodiment, the cutter is connected to the power output end of the drive device, and the drive device drives the pressure block and the cutter to move; after the drive device drives the pressure block to seal the packaging bag, the drive device drives the cutter to cut the seal.

[0020] As a preferred embodiment, the packaging bag is a fusible packaging bag, which is melted into the material when the material is heated and melted.

[0021] A packaging structure for a fusible bag for viscous materials, characterized in that it includes: Packaging bags are used for packaging materials; The mother packaging bag is placed over the outer packaging bag; The outer packaging is placed over the mother packaging bag and is used to package both the mother packaging bag and the outer packaging bag.

[0022] The packaging bag contains materials, and the packaging bag is sealed together by the material pressure; the mother packaging bag is placed outside the packaging bag to isolate the packaging bag and the outer packaging body, forming a mother-daughter bag packaging structure.

[0023] As a preferred embodiment, the mother packaging bag contains at least two packaging bags.

[0024] As a preferred embodiment, the mother packaging bag contains a packaging bag inside the outer packaging bag.

[0027] As a preferred embodiment, the mother packaging bag has an open end structure with the opening facing upwards; inside the outer packaging, the opening is either closed or open.

[0028] As a preferred embodiment, the outer packaging is in the shape of a box or a barrel.

[0029] The present invention has the following beneficial effects: 1. This utility model continuously feeds material into the packaging bag during the filling process. During filling, the material flows in a waterfall-like stream towards the bottom of the bag. Once the set value is reached, the corresponding position of the packaging bag is sealed. At this point, the seal contains material, which, due to its high viscosity, acts as an adhesive to the seal. Simultaneously, the material flows into the previous packaging bag, achieving the function and purpose of simultaneously sealing the next bag and filling the previous one, greatly improving production efficiency. Furthermore, the sealing of the packaging bag does not require heat sealing, saving energy consumption; it also eliminates the need for additional glue, reducing the glue application process and saving glue usage, thus improving work efficiency and reducing production costs.

[0030] 2. In the process of sealing, this utility model uses a cooling device to cool the seal, which can quickly cool the material trapped inside the seal, allowing the material to better adhere to the seal of the packaging bag and improve the stability of the adhesion.

[0031] 3. This utility model achieves a sealing process where, after the sealing process begins, the upper seal of the next packaging bag is already sealed, while the lower seal of the previous packaging bag is also sealed simultaneously. This means that two packaging bags can be sealed in a single operation. The ingenious structure divides the sealing area into upper and lower parts, allowing for simultaneous sealing of both the lower and upper packaging bags, simplifying the sealing process and significantly improving sealing efficiency.

[0032] 4. This utility model uses a mother packaging bag placed outside the outer packaging bag, i.e., the mother packaging bag is positioned between the outer packaging bag and the outer packaging body, thus isolating the two. When material leaks from the sealed packaging bag, the leaked material adheres directly to the mother packaging bag and not to the outer packaging body. When the material needs to be heated for use, simply lift the mother packaging bag and throw it onto the melting furnace for heating; the outer packaging body will not be adhered to by the leaked material. Therefore, the outer packaging body can be treated as general waste without special treatment, improving ease of use. Because both the packaging bag and the mother packaging bag are fusible, they are melted into the material during heating and melting. Therefore, the mother packaging bag with leaked material is melted into the material, eliminating the need for special treatment. The entire packaging structure greatly improves the convenience of packaging and use and does not pollute the environment. Attached Figure Description

[0040] 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. Example

[0041] Reference Figures 1 to 4 This embodiment relates to a method for sealing fusible bags of high-viscosity filling materials, including the following steps: S1. Fill the material into the packaging bag 1. After filling to the set value, seal the packaging bag 1 with a pressure seal. S2. Cut the seal 11 of the packaging bag 1 to make the canned and sealed packaging bag 1 fall off.

[0042] During the sealing process in step S1, materials are continuously filled into the packaging bag 1. At the same time, the materials flowing through the seal 11 of the packaging bag 1 are pressed against the seal 11 of the packaging bag 1, causing the materials to adhere to the seal 11.

[0043] The packaging bag 1 in this method is a long packaging bag that can be used to package multiple packaging bags 1. During the filling process, material is continuously poured into the packaging bag 1; during the filling process, the material forms a waterfall flow that continuously flows to the bottom of the packaging bag 1; when the set value is reached, the corresponding position of the packaging bag 1 is pressed and sealed. At this time, the seal 11 at that position contains material, and due to the high viscosity of the material, it can act as an adhesive for the seal 11. At the same time, the material continuously flows into the previous packaging bag 1, realizing the function and purpose of sealing the next packaging bag 1 and filling the previous packaging bag 1 simultaneously, which greatly improves the production efficiency. In addition, the sealing 11 of the packaging bag 1 does not require heat-pressing, saving energy consumption; of course, it also does not require the use of glue for bonding, reducing the glue application process and saving glue usage, which improves work efficiency and saves production costs.

[0044] In step S1, during the sealing process, cold pressing is applied to the seal 11 of the packaging bag 1, allowing the material at the seal 11 to cool and achieve cooling adhesion. When the material temperature is too high, the material has strong fluidity but poor adhesion, resulting in low adhesion effect and stability. As the temperature decreases, the adhesion gradually increases and stabilizes. During the sealing process of the seal 11, cooling the seal 11 quickly lowers the temperature of the material trapped within it, allowing the material to better adhere to the seal 11 of the packaging bag 1 and improving adhesion stability.

[0045] Specifically, in step S1, before filling, the packaging bag 1 is first placed onto the feeding port of the filling device 2. After filling to the set value, the sealing device 3 seals the opening 11 of the packaging bag 1. During the filling process, the filling device 2 does not need to stop working, but is in a state of continuous material output until the packaging bag 1 is used up. It can be seen that when the sealing device 3 is working, the filling device 2 is also working at the same time, that is, the filling and sealing processes can be carried out simultaneously, which greatly improves the efficiency of the work.

[0046] The sealing device 3 is equipped with a cooling device 4 for cooling the seal 11 of the packaging bag 1. The cooling device 4 is installed on the sealing device 3. When the sealing device 3 seals the seal 11, the cooling device 4 simultaneously cools the material sandwiched inside the seal 11 of the packaging bag 1, so that the material can more quickly and better adhere to the seal 11 and improve the stability of the adhesion.

[0047] In step S2, when cutting the seal 11, it is divided into upper and lower parts. The lower part is the upper seal 11 of the next packaging bag 1, and the upper part is the lower seal 11 of the previous packaging bag 1. After the seal 11 is pressed, the upper seal 11 of the next packaging bag 1 is sealed, and the lower seal 11 of the previous packaging bag 1 is also sealed. This means that the sealing process can be completed in one step. This structure cleverly divides the seal 11 into upper and lower parts, thereby achieving simultaneous sealing of the lower and upper packaging bags 1, simplifying the sealing process and greatly improving the efficiency of sealing.

[0048] The material has a high viscosity. For example, asphalt. Alternatively, the material can be a paste or semi-solid material that has high fluidity and viscoelasticity at room temperature, such as pressure-sensitive adhesive (pesticide adhesive) used for pest control.

[0049] This embodiment also provides an apparatus for sealing a fusible bag for viscous materials, including a filling device 2 for filling the packaging bag 1 with materials, a sealing device 3 for pressing the seal 11 of the packaging bag 1, a cutting device 5 for cutting the seal 11 of the filled and sealed packaging bag 1, and a cooling device 4 for cooling the seal 11 of the packaging bag 1; the seal 11 contains materials, and under the pressure of the sealing device 3, the materials adhere to the seal 11, that is, the materials adhere and seal the seal 11 through the sealing device 3.

[0050] During the filling process, the filling device 2 continuously feeds material into the packaging bag 1. The material forms a waterfall flow that continuously flows towards the bottom of the packaging bag 1. After a certain amount is filled, the structure uses a sealing device 3 to seal the corresponding position on the packaging bag 1, thus cutting off the waterfall flow at that position, forming an upper packaging bag 1 and a lower packaging bag 1. At this time, the lower packaging bag 1 is sealed 11, while the upper packaging bag 1 is continuously filled with material, greatly improving production efficiency. The sealing device 3 clamps the material at the sealing position 11, causing the material to adhere to the sealing position 11, thereby achieving the function and purpose of sealing 11. Therefore, the sealing position 11 of the packaging bag 1 does not require heat-pressing, saving energy consumption; similarly, it does not require additional glue, reducing the glue application process and saving glue usage, thus improving work efficiency and saving production costs.

[0051] The cooling device 4 is mounted on the sealing device 3. While the sealing device 3 is pressing the seal 11 of the packaging bag 1, the cooling device 4 cools the material inside the seal 11, causing the material to adhere to the seal 11 of the packaging bag 1, thus achieving sealing. During the sealing process, the cooling device 4 simultaneously cools the seal 11 through the sealing device 3, allowing for simultaneous sealing and cooling. This enables faster cooling of the material trapped inside the seal 11, allowing the material to better adhere to the seal 11 of the packaging bag 1 and improving the stability of the adhesion.

[0052] The sealing device 3 includes a frame 31, a pressing block 32 mounted on the frame 31 for pressing the seal 11 of the packaging bag 1, and a drive device 33 for driving the pressing block 32. A cooling device 4 cools the seal 11 of the packaging bag 1 via the pressing block 32. The cooling device 4 keeps the pressing block 32 at a low temperature; while pressing the seal 11 of the packaging bag 1, the pressing block 32 both seals and cools the material trapped within the seal 11.

[0053] The cutting device 5 includes a cutter 51, which cuts the seal 11 of the packaging bag 1 by driving its movement. When cutting the seal 11, the cutter 51 divides it into upper and lower parts. The lower part becomes the upper seal 11 of the next packaging bag 1, and the upper part becomes the lower seal 11 of the previous packaging bag 1. This structure cleverly divides the seal 11 into upper and lower parts, thereby enabling simultaneous sealing of both the lower and upper packaging bags 1, simplifying the sealing process and greatly improving the efficiency of the sealing process.

[0054] The cutter 51 is connected to the power output of the drive unit 33, which drives the pressure block and the cutter 51 to move. After the drive unit 33 drives the pressure block to seal the opening 11 of the packaging bag 1, the drive unit 33 drives the cutter 51 to cut the opening 11. This structure uses one drive unit 33 to simultaneously drive the pressure block to seal the opening 11 of the packaging bag 1 and drive the cutter 51 to cut the sealed opening 11 of the packaging bag 1. This reduces the number of motors used, saves on hardware costs, and reduces energy consumption. Figure 3 As shown, the driving device 33 includes a motor 331 and a transmission mechanism 332. The motor 331 drives the pressing block 32 and the cutter 51 to work simultaneously through the transmission mechanism 332, so that the two can work together. That is, when the motor 331 drives the transmission mechanism 332 to move, the pressing block 32 seals the seal 11 of the packaging bag 1, and then the cutter 51 moves to the seal 11 position to cut the seal 11.

[0055] The packaging bag 1 is a fusible packaging bag 1, which is melted into the material when it is heated and melted. The material of the packaging bag 1 in this structure is prior art, as can be found in the utility model patent with patent number "202010497914.9" entitled "A modified film for hot melt adhesive packaging and its preparation method". When the material is heated to the required temperature, the packaging bag 1 is melted into the material, eliminating the need to cut the packaging bag 1 to pour out the material, or to scoop the packaging bag 1 out of the material after it has melted, greatly facilitating the use of the packaging bag 1. Furthermore, since the packaging bag 1 is directly melted into the material, there is no need for chemical packaging treatment of the used packaging bag 1, reducing environmental pollution.

[0056] This embodiment also provides a packaging structure for a fusible bag for viscous materials, such as... Figure 1 , Figure 4 and Figure 5 As shown, the packaging includes a packaging bag 1 (sub-bag) for packaging materials, a mother packaging bag 112 fitted over the packaging bag 1, and an outer packaging body 113 fitted over the mother packaging bag 112. The outer packaging body 113 is used to package the mother packaging bag 112 and the packaging bag 1. The packaging bag 1 contains materials, and the seal 11 of the packaging bag 1 is sealed together by the material. The mother packaging bag 112 is fitted over the packaging bag 1 to isolate the packaging bag 1 and the outer packaging body 113, forming a mother-and-child bag packaging structure. The outer packaging body 113 is generally made of cardboard, but other materials are also suitable. The material is asphalt, or it can be a paste or semi-solid material with high fluidity and high viscoelasticity at room temperature.

[0057] The seal 11 in this structure utilizes the high viscosity of the material for sealing. If the outer packaging 113 is used to directly package the bag 1, during transportation, high temperatures will increase the fluidity and decrease the viscosity of the material at the seal 11, causing the material inside the bag 1 to leak from the seal 11 and adhere directly to the outer packaging 113. Since the material (e.g., asphalt) is a chemical, the outer packaging 113 with the adhered material requires special treatment and cannot be treated as general waste, leading to increased waste disposal costs and environmental pollution. This structure uses a mother packaging bag 112 placed outside the bag 1, i.e., the mother packaging bag 112 is positioned between the bag 1 and the outer packaging 113, thus isolating the bag 1 and the outer packaging 113. When material leaks from the seal 11 of the bag 1, the leaked material adheres directly to the mother packaging bag 112 and not to the outer packaging 113. When the material needs to be heated for use, simply lift the mother packaging bag 112 and throw it onto the melting furnace for heating. The outer packaging body 113 will not be adhered to by the leaked material. Therefore, the outer packaging body 113 can be treated as general waste without special treatment, improving ease of use. Because the packaging bag 1 and the mother packaging bag 112 are fusible packaging bags, when the material is heated and melted, the packaging bag 1 and the mother packaging bag 112 are melted into the material. Therefore, the mother packaging bag 112 with leaked material is melted into the material, and no special treatment is required for the mother packaging bag 112. The entire packaging structure greatly improves the convenience of packaging and use, and will not cause environmental pollution.

[0058] The mother packaging bag 112 contains at least two packaging bags 1. To improve the utilization rate of the mother packaging bag 112, at least two packaging bags 1 are contained in one mother packaging bag 112. Alternatively, a packaging structure can be adopted in which one packaging bag 1 is contained in one mother packaging bag 112. After the packaging bag 1 is placed inside the mother packaging bag 112, the mother packaging bag 112 is then placed inside the outer packaging body 113. When a packaging structure in which one packaging bag 1 is contained in one mother packaging bag 112 is adopted, the outer packaging body 113 contains at least two mother packaging bags 112 with packaging bags 1. In this case, multiple mother packaging bags 112 are contained in one outer packaging body 113.

[0059] The mother packaging bag 112 has an opening 114 at one end, with the opening 114 facing upwards; inside the outer packaging body 113, the opening 114 is either closed or open. Because the material has high viscosity, its flowability is poor; material leaking from the packaging bag 1 will adhere directly to the mother packaging bag 112 and will not flow from the opening 114 of the mother packaging bag 112 to the outer packaging body 113. Therefore, there is no need to seal or tie the opening 114 of the mother packaging bag 112, improving packaging efficiency. Of course, the opening 114 of the mother packaging bag 112 can also be tied with a rope or simply folded inside the outer packaging body 113.

[0060] The outer packaging 113 is in the shape of a box or a barrel; of course, other irregular shapes are also suitable for this invention. The outer packaging 113 can be made of cardboard boxes, plastic barrels, or iron barrels, etc. Example

[0061] This embodiment is an improvement on the cooling method and structure based on embodiment 1. In this embodiment, during the sealing process of the seal 11, the seal 11 is not cooled at the same time. Instead, step S3 is adopted to transport the fallen packaging bag 1 to the cooling pool, and the material at the seal 11 is cooled by the coolant in the cooling pool to achieve cooling and bonding.

[0062] After the seal 11 is cut, the packaged bag 1 containing the material and sealed with the seal 11 falls into the cooling pool. The cooling pool cools the material trapped inside the seal 11 to increase the viscosity of the material, thereby allowing the material to better adhere to the seal 11 of the packaged bag 1. The coolant in the cooling pool is circulating water, which can better improve the cooling effect on the seal 11 of the packaged bag 1.

[0063] The cooling device 4 is a cooling pool. The packaging bag 1 falls into the cooling pool, thereby cooling the material inside the seal 11. The cooling pool is located below the packaging bag 1. The cooling pool can be located directly below the packaging bag 1, allowing the packaging bag 1 to fall directly into the cooling pool for cooling, or the packaging bag 1 can first fall onto a conveyor belt, then be transported by the conveyor belt to the top of the cooling pool, and then fall into the cooling pool for cooling.

[0064] The above-disclosed embodiment is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
