[0002] The description in this section provides only background information related to the disclosure of this utility model and does not constitute prior art.

[0003] Ordinary packaging bags have only one packaging space to hold the material. They can only be filled with a single material during packaging. If different materials need to be mixed at the same time, at least two separate packaging bags are required, and two packaging bags need to be opened at the same time and squeezed together for use.

[0004] There is a concept for a spacer bag with multiple compartments, which can accommodate various materials through an inner film between the outer packaging, thus improving the functionality and practicality of the original packaging bag. However, there is currently no efficient equipment to produce such a spacer bag, or a modification of existing production lines for ordinary packaging bags. Its structure is complex, difficult to maintain, and costly, resulting in poor practicality.

[0005] Currently, there is no packaging bag production equipment that can solve the above problems. Utility Model Content

[0016] Furthermore, the number of inner layers is one, such that the spacer bag forms two compartments on both sides of the inner layers, and the filling mechanism includes two filling tubes, the positions of which correspond one-to-one with the positions of the two compartments.

[0017] Furthermore, the number of inner membranes is at least two, and the number of third feeding devices corresponds one-to-one with the number of inner membranes, with each third feeding device corresponding to one inner membrane.

[0032] See Figure 1 and Figure 4 This embodiment provides a packaging bag production apparatus for producing spacer bags. The spacer bag includes a first outer film 100, a second outer film 200, and an inner film 300 between the first outer film 100 and the second outer film 200. The spacer bag includes multiple compartments separated by the inner film. The packaging bag production apparatus includes:

[0033] The first feeding device 11 is used to convey the first outer film 100 downstream;

[0034] The second feeding device 12 is used to convey the second outer film 200 downstream;

[0035] The third feeding device 2 is used to convey the inner layer film 300 downstream and to position at least a portion of the inner layer film 300 between the first outer layer film 100 and the second outer layer film 200.

[0036] The heat sealing mechanism 3 is located downstream of the first feeding device 11, the second feeding device 12, and the third feeding device 2. The heat sealing mechanism 3 is used to heat seal the corresponding positions of the first outer film 100, the inner film 300, and the second outer film 200.

[0037] The first cutting mechanism 5 is located downstream of the heat sealing mechanism 3 and is used to cut the heat-sealed spacer packaging bag.

[0038] The filling mechanism 4 is located upstream of the heat sealing mechanism 3. The filling mechanism 4 includes multiple filling pipes 41, and the multiple filling pipes 41 correspond one-to-one with the positions of multiple compartments.

[0039] With the above structure, in use, the operator first needs to install the first outer film 100 and the second outer film 200 of sufficient length at the corresponding positions of the first feeding device 11 and the second feeding device 12. Then, the operator installs the inner film 300, which matches the length of the first outer film 100 and the second outer film 200, at the corresponding position of the third feeding device 2. The first outer film 100, the second outer film 200 and the inner film 300 are then stretched and threaded through to the downstream end of the heat sealing mechanism 3, the filling mechanism 4 and the first cutting mechanism 5 arranged in sequence. The filling mechanism 4 prepares a sufficient volume of material for filling into the spacer bag. Then, the packaging bag production device of this embodiment is started. After startup, when the first outer film 100, the second outer film 200, and the inner film 300 reach the position of the heat-sealing mechanism 3, the heat-sealing mechanism 3 simultaneously compresses and heats the first outer film 100 and the second outer film 200 in two directions perpendicular to them, so that the first outer film 100, the second outer film 200, and the inner film 300 are heat-sealed to form a sealing line; then, the filling mechanism 4 starts to operate, and multiple filling pipes 41 simultaneously fill the corresponding compartments. When the filling is completed and the compartments are full of material, the filling mechanism 4 stops operating; then, the first outer film 100, the second outer film 200, and the inner film 300 continue to move downstream, when When the sealing line reaches the position of the first cutting mechanism 5, the first cutting mechanism 5 cuts the sealing line on one side downstream of the sealing line, or the sealing line itself. Immediately afterwards, the heat-sealing mechanism 3 performs a second heat seal on the first outer film 100, the second outer film 200, and the inner film 300 on the upstream side of the filled material, forming a second sealing line. At this point, the material in the compartment is completely sealed. Then, the first outer film 100, the second outer film 200, and the inner film 300 continue to be passed downstream until the second sealing line reaches the position of the first cutting mechanism 5. The first cutting mechanism 5 then cuts the second sealing line on one side downstream of the second sealing line, or the second sealing line itself. At this point, a complete spacer bag falls out, and the finished spacer bag is complete. It is worth noting that if the first cutting mechanism 5 cuts the sealing line on one side downstream of the sealing line, an additional sealing line needs to be heat-sealed before the cutting position. The cutting position is between the two sealing lines. This avoids directly cutting the sealing line, making the cutting process easier.

[0040] In the above process, the first feeding device 11, the second feeding device 12, and the third feeding device 2 operate in coordination, while the downstream heat sealing mechanism 3, the filling mechanism 4, and the first cutting mechanism 5 work together to process the first outer film 100, the second outer film 200, and the inner film 300 simultaneously. This allows the packaging bag production device of this embodiment to process spaced packaging bags with multiple compartments, based on the existing packaging bags that can only process single-filler packaging bags. Moreover, the structure is simple and can even be modified based on the existing first feeding device 11 and second feeding device 12 to achieve a lower manufacturing cost.

[0041] Furthermore, in this embodiment, the first feeding device 11, the second feeding device 12, and the third feeding device 2 are configured as roller-shaped structures with width dimensions matching the first outer film 100, the second outer film 200, and the inner film 300. They can spin in a specified direction and speed under external electric drive, and convey the first outer film 100, the second outer film 200, and the inner film 300 downstream. At the same time, the first feeding device 11, the second feeding device 12, and the third feeding device 2 are connected to an external control mechanism, and their spinning can be started and stopped as needed. This allows some areas of the first outer film 100, the second outer film 200, and the inner film 300 to pause briefly when being heat-sealed by the heat-sealing mechanism 3, when being filled by the filling mechanism 4, and when being cut by the first cutting mechanism 5. This results in better heat sealing, neater cutting, and more stable and accurate filling. Specifically, the inner sides of the first outer membrane 100 and the second outer membrane 200 are made of hot-melt material facing each other, while the inner membrane 300 between the first outer membrane 100 and the second outer membrane 200 is made of hot-melt material on both sides, so that a corresponding sealed space can be formed after heating by the heat sealing mechanism 3.

[0042] Furthermore, if Figure 1 As shown, it also includes guide wheels 6, with multiple guide wheels 6 attached to and supported on at least one side of the first outer film 100, the second outer film 200, or the inner film 300. In this embodiment, at least two guide wheels 6 are included downstream of the third feeding device 2 to stretch and fold the inner film 300 by the multiple guide wheels 6, and to store a certain amount of the inner film 300 pulled out. Stretching the inner film 300 helps maintain appropriate tension, ensuring that the inner film 300 remains flat throughout the processing, without wrinkles or loosening, thereby improving the quality of the finished product. It also eliminates stress and deformation of the inner film 300 and improves heat-sealing performance.

[0043] Of course, the intervention of multiple guide wheels 6 during the operation of the first outer membrane 100 and the second outer membrane 200 can still achieve the above-mentioned effects of maintaining flatness and eliminating stress. For the sake of simplifying the illustration, these effects are not shown in the figure.

[0044] Furthermore, there is only one inner film 300, so that the spacer bag forms two compartments on both sides of the inner film 300. The filling mechanism includes two filling tubes 41, and the positions of the two filling tubes 41 correspond one-to-one with the two compartments. For general market demand, a spacer bag with two compartments already meets most functional requirements. Moreover, if there are multiple layers of inner film 300, the flow line of the third feeding device 2 will be more complex, and the cost will increase dramatically, which is not worthwhile. Therefore, in this embodiment, according to actual market needs, a single inner film 300 is set to match two compartments. Therefore, the filling mechanism 4 has two filling tubes 41 corresponding to the two compartments, realizing efficient filling and assembly line operation speed.

[0045] Of course, in another embodiment, the number of inner layer films 300 is at least two, and the number of third feeding devices 2 corresponds one-to-one with the number of inner layer films 300, with each third feeding device 2 corresponding to one inner layer film 300. In this embodiment, to meet personalized market demands, such as producing a four-compartment spacer bag product, three inner layer films 300 and three third feeding devices 2 matching the three inner layer films 300 are required. The three third feeding devices 2 are alternately arranged, and when the three inner layer films 300 move to the filling mechanism 4, the four filling pipes 41 of the filling mechanism 4 correspond to the four compartments and fill synchronously. The starting point of the above embodiment is the same as that of the previous embodiment, which is the superposition of third feeding devices 2 according to actual needs, not shown in the figure.

[0046] Furthermore, if Figure 1 As shown, the first feeding device 11 is used to roll up the first outer film 100, and the second feeding device 12 is used to roll up the second outer film 200. With this structure, the first outer film 100 and the second outer film 200, which serve as the main body of the spacer packaging bag, are transported and installed separately on two rollers. The two rollers can be adjusted independently, providing greater space for maintenance and adjustment during operation. Specifically, in this embodiment, the first feeding device 11 and the second feeding device 12 are respectively located on opposite sides of the inner film, so that after the first outer film 100, the second outer film 200, and the inner film 300 are jointly conveyed to the designated position, the first outer film 100 and the second outer film 200 are precisely positioned on opposite sides of the front side of the inner film 300, allowing for direct and rapid heat sealing and filling operations.

[0047] In another embodiment, such as Figure 2As shown, it also includes a base film 400 and a fourth feeding device 13. The fourth feeding device 13 is used to convey the base film 400 downstream. The base film 400 is composed of a first outer film 100 and a second outer film 200. Downstream of the fourth feeding device 13, there is a second cutting mechanism 7. The second cutting mechanism 7 is used to cut the base film 400 from the fourth feeding device 13 into first outer films 100 and second outer films 200 of equal size. With the above structure, the first outer film 100 and the second outer film 200, which are the main body of the spacer packaging bag, are separated from the same roll of base film 400 and then transported and installed separately. The cost is controllable, and the dimensions of the first outer film 100 and the second outer film 200 are necessarily coordinated and equal.

[0048] Furthermore, if Figure 3 As shown, in this embodiment, the third feeding device 2 and the guide wheel 6 are supported by two mirror-mounted frames 9 as a skeleton. The third feeding device 2 and the guide wheel 6 are fixed between the two frames 9. At the same time, the two frames 9 are fixed on a base 8 with a large support surface. Through the support structure of the base 8 and the frame 9 in this embodiment, the third feeding device 2 and the guide wheel 6 can be quickly and effectively connected with various types of external first feeding devices 11 and second feeding devices 12 to achieve customized assembly.
