AI Technical Summary
Existing bag-making machines often cause packaging bags to scatter after production, requiring manual sorting by workers, which reduces efficiency. Furthermore, due to their low rigidity and thinness, the bags tend to bend at the head and stagnate at the tail, making them difficult to align and stack.
Design a material collection mechanism that uses airflow to lift the head of the packaging bag. Through the coordinated control of the first and second air outlet plates, ensure that the packaging bag smoothly enters the dropping frame and is stacked in alignment within the dropping frame, reducing manual handling time.
It enables automatic alignment and stacking of packaging bags, improving production efficiency and smoothness, reducing manual handling time, and avoiding folding and jamming problems caused by low rigidity of packaging bags.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of bag making machine technology, and in particular to a material collection mechanism applied to a bag making machine. Background Technology
[0002] According to the authorized patent CN223085572U, "A bag making machine with a material collection mechanism" (hereinafter referred to as "the prior art"), a bag making machine is a type of plastic packaging machinery used to make plastic woven bags. The bag making machine is usually composed of a cutting device, a feeding device, a heat sealing device, an edge rolling device, a folding device, and a bag forming device.
[0003] After the current bag-making machine finishes producing the packaging bags, the bags fall from one side of the machine. Workers often place a table at the discharge port of the bag-making machine to collect the produced packaging bags. However, the large number of packaging bags that are produced fall onto the table and are scattered randomly on the surface. As a result, when workers pick up the packaging bags for subsequent processing, they still need to manually sort them, which increases the workload of the workers and reduces the efficiency of the work.
[0004] In summary, existing bag-making machines lack a system for collecting the produced packaging bags, which causes them to easily fall off and scatter.
[0005] While the comparative document suggests that by collecting the produced packaging bags at the feeding port, the bags can be automatically aligned and sorted after the batch is produced, making them easier for workers to handle, the actual production process still has the following shortcomings. For example, due to the low rigidity and thinness of the packaging bags, when the bags are output from the bag-making machine, the head bends and droops into the collection area first, while the tail is still on the conveying path due to the lag in the conveying process. This results in the tail not falling flat with the head, causing folding, stacking, and misalignment of the packaging bags.
[0006] Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content
[0007] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the aforementioned problems.
[0008] To achieve the above objectives, this utility model provides the following technical solution: a material collection mechanism for a bag making machine, including a material dropping frame with an upper opening, and a receiving plate provided on one side of the upper end of the material dropping frame, the receiving plate being used to connect with the discharge end of the bag making machine.
[0009] The upper edge of the material drop frame near the receiving plate has a slot, and a first air outlet plate is provided in the slot. The first air outlet plate has a cavity structure inside. Multiple first air outlets are provided on the side of the first air outlet plate facing the inside of the material drop frame. The first air outlets are connected to the cavity structure. Multiple first air pipe interfaces are provided on the side of the first air outlet plate away from the material drop frame.
[0010] As a further embodiment of this utility model: both sides of the upper end of the material discharge frame are provided with a second air outlet plate with an internal cavity structure, the lower end of the second air outlet plate is provided with a plurality of second air outlets, and the upper end of the second air outlet plate is provided with a plurality of second air pipe interfaces.
[0011] As a further embodiment of this utility model: the lower end of the second air outlet plate is surrounded by an flared frame along its edge.
[0012] As a further embodiment of this utility model: multiple ventilation openings are provided on the inner wall of the material dropping frame on the side symmetrical to the first air outlet plate.
[0013] As a further embodiment of this utility model: material picking slots are provided on both sides of the material dropping frame, and the two material picking slots are symmetrical and staggered from the slot opening and the ventilation opening.
[0014] As a further embodiment of this utility model, limit plates are provided on both sides of the receiving plate.
[0015] As a further embodiment of this utility model: the second air outlet plate is connected to two fixing plates on both sides, and the fixing plates are connected to the outer wall of the material dropping frame.
[0016] As a further embodiment of this utility model: a support frame is connected to the lower end of the material dropping frame.
[0017] Compared with the prior art, the beneficial effects of this technical solution are as follows: When the head of the packaging bag falls from the receiving plate into the dropping frame, the multiple first air outlets of the first air outlet plate blow air evenly into the dropping frame. Since the first air outlet plate is located at the top, the airflow is concentrated at the top of the dropping frame, and the airflow blows the head of the packaging bag to lift the head of the packaging bag. Then the rear end of the packaging bag continues to be conveyed into the dropping frame until the packaging bag is completely conveyed into the dropping frame. Then the first air outlet plate stops conveying airflow, and the packaging bag loses the support of the airflow below and begins to fall to the bottom of the dropping frame 1. This can improve the situation where the packaging bag cannot be aligned and stacked or folded during the process of entering the dropping frame from the bag making machine due to its own rigidity and light weight. It reduces the time for manual sorting and improves production efficiency and production smoothness.
[0018] The airflow blowing from the first air outlet into the material drop frame not only has a lifting effect, but also guides the head of the packaging bag to the other side of the material drop frame due to the direction of the airflow, so as to further prevent the tail of the packaging bag from getting stuck outside the material drop frame due to the head bending.

Detailed Implementation
[0027] 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.
[0028] Please see Figure 1-4A material collection mechanism for a bag making machine includes a material dropping frame 1 with an upper opening, and a receiving plate 2 is provided on one side of the upper end of the material dropping frame 1. The receiving plate 2 is used to connect with the discharge end of the bag making machine.
[0029] A slot 11 is provided on the upper edge of the material drop frame 1 near the receiving plate 2. A first air outlet plate 3 is provided in the slot 11. The first air outlet plate 3 has a cavity structure inside. Multiple first air outlets 31 are provided on the side of the first air outlet plate 3 facing the inside of the material drop frame 1. The first air outlets 31 are connected to the cavity structure. Multiple first air pipe interfaces 32 are provided on the side of the first air outlet plate 3 away from the material drop frame 1. The first air pipe interfaces 32 are connected to the air source pipe.
[0030] Specifically, in this technical solution, the dropping frame 1 provides space for the packaging bag, while the receiving plate 2 connects to the discharge end of the bag-making machine, providing a transitional receiving structure for the packaging bag's transport from the bag-making machine to the dropping frame, ensuring the smoothness and continuity of the packaging bag's transport path. When the head of the packaging bag falls from the receiving plate 2 into the dropping frame 1, an air source (such as an air pump) delivers gas into the first air outlet plate 3 through the first air pipe interface 32. The gas is then evenly blown into the dropping frame 1 through multiple first air outlets 31. Because the first air outlet plate 3 is positioned high, the airflow is concentrated. At the top of the drop box 1, the airflow blows the head of the packaging bag to lift the head of the packaging bag. Then the rear end of the packaging bag is continuously conveyed into the drop box 1 until the packaging bag is completely conveyed into the drop box 1. Then the first air outlet plate 3 stops conveying airflow. The packaging bag loses the support of the airflow below and begins to fall to the bottom of the drop box 1. This can improve the situation where the packaging bag cannot be aligned and stacked or folded during the process of entering the drop box 1 from the bag making machine due to its own rigidity and light weight. It reduces the time for manual sorting and improves production efficiency and production smoothness.
[0031] The airflow blown from the first air outlet 31 into the material drop frame 1 not only has a lifting effect, but also guides the head of the packaging bag to the other side of the material drop frame 1 due to the direction of the airflow, so as to further avoid the situation where the tail of the packaging bag gets stuck outside the material drop frame 1 due to the head bending.
[0032] Based on the above embodiments, it is further proposed that multiple ventilation openings 12 are provided on the side of the inner wall of the material dropping frame 1 that is symmetrical to the first air outlet plate 3.
[0033] Specifically, the opening of the vent 12 allows the airflow blown out from the first air outlet 3 to be discharged outwards, instead of flowing back after contacting the inner wall of the material drop frame 1, thus avoiding airflow disturbance that could cause instability in the overall posture of the packaging bag.
[0034] Based on the above embodiments, it is further proposed that the upper two sides of the material discharge frame 1 are provided with a second air outlet plate 4 with an internal cavity structure, the lower end of the second air outlet plate 4 is provided with a plurality of second air outlets 41, and the upper end of the second air outlet plate 4 is provided with a plurality of second air pipe interfaces 42, which are connected to the air source pipe.
[0035] Specifically, after the packaging bag is completely inside the drop box 1, the first air outlet plate 3 stops blowing airflow onto the packaging bag. At this time, the air source (such as an air pump) delivers gas into the second air outlet plate 4 through the second air pipe interface 42, and then blows airflow downward through the second air outlet 41, which acts on the packaging bag inside the drop box 1, so that the packaging bag can fall to the bottom of the drop box 1 at a faster speed, so as to avoid the previous packaging bag from being folded at the edge by the airflow blown by the first air outlet plate 3 before it has fallen to the bottom when the next packaging bag arrives.
[0036] Preferably, in this embodiment, the coordinated movement of the first air outlet plate and the second air outlet plate (i.e., when the first air outlet plate blows out airflow and when the second air outlet plate blows out airflow) is achieved by an industrial controller. This control method is a mature existing technology in the field of automation, and will not be elaborated on here.
[0037] Based on the above embodiments, it is further proposed that the lower end of the second air outlet plate 4 is surrounded by a flared frame 43. The flared frame 43 allows the airflow blown from the second air outlet plate 4 to cover a wider range, so that more areas of the packaging bag are pushed by the airflow and the force is even.
[0038] Based on the above embodiments, it is further proposed that the material feeding frame 1 has material picking slots 13 on both sides, the two material picking slots 13 are symmetrical and staggered from the slot opening 11 and the ventilation opening 12.
[0039] Specifically, when a certain number of packaging bags are collected inside the drop box 1, various honors can lift the stacked packaging bags from the bottom through the material picking slot 13 opened in the drop box 1 process, and take them out from inside the drop box 1.
[0040] Based on the above embodiments, it is further proposed that limit plates 21 are provided on both sides of the receiving plate 2 to limit the left and right deviation of the packaging bag, ensuring that it is centered when it is conveyed to the dropping frame 1, and avoiding the head and tail from being misaligned and folded due to deviation when blown by the airflow.
[0041] Based on the above embodiments, it is further proposed that the second air outlet plate 4 is connected to the two sides of the fixing plate 5, and the fixing plate 5 is connected to the outer wall of the material drop frame 1, so as to fix the second air outlet plate 4 above the material drop frame 1.
[0042] Based on the above embodiments, it is further proposed that the lower end of the material drop frame 1 is connected to a support frame 6 to match the height of the material discharge end of the bag making machine.
[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
