[0025] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] The utility model provides a single material PE film splitting bag device, which can split the connected film material into multiple independent bag bodies. Figure 1 as well as Figure 2 As shown, the device for dividing a single-material PE film into bags comprises a conveying unit 10, a clamping unit 20 and a dividing unit 30, wherein:

[0027] The single-material PE film is wound on a reel before being conveyed. The single-material PE film is a film material with closed sides and openings at the top and bottom. One end of the single-material PE film is placed on the conveying unit 10. Under the action of the conveying unit 10, the single-material PE film is continuously conveyed along the first direction D1 to the clamping unit 20. In the embodiment provided in the present application, the first direction D1 is the direction of gravity, the clamping unit 20 and the splitting unit 30 are arranged below the conveying unit 10, and the conveying unit 10 continuously conveys the single-material PE film downward.

[0028] The clamping unit 20 includes a first driving member 21 and a clamping member 22. When one end of the single-material PE film enters the clamping unit 20, the first driving member 21 drives the clamping member 22 to move along the second direction D2, the second direction D2 being the horizontal direction, and the clamping member 22 approaches the single-material PE film along the horizontal direction until the single-material PE film is clamped and fixed, and then the opening at the end of the single-material PE film is sealed by the heat-sealing member 23 on the clamping member 22. The heat-sealing member 23 can adopt a structure or component used for bag sealing in the prior art, which will not be described in detail here.

[0029] After the end of the single-material PE film is sealed, the splitting unit 30 cuts the single-material PE film from the sealed portion, and the cut portion forms an independent bag body. In the embodiment provided by the present application, the splitting unit 30 includes a second driving member 31 and a splitting member 32, and the splitting member 32 is located below the heat-sealing member 23 in the direction of gravity. When the clamping unit 20 approaches the single-material PE film, the splitting unit 30 also approaches the single-material PE film. When the clamping unit 20 clamps the single-material PE film, there is a certain distance between the splitting unit 30 and the single-material PE film. After the single-material PE film is sealed, the second driving member 31 drives the splitting member 32 to further approach the single-material PE film, and cuts the single-material PE film below the sealed portion of the single-material PE film.

[0030] In a feasible implementation mode, referring to Figure 3 As shown, the clamping member 22 includes a clamping block 221 and a fixed block 222. The fixed block 222 is arranged below the conveying unit 10. During the downward conveying of the single-material PE film, the single-material PE film is located between the fixed block 222 and the clamping block 221. The first driving member 21 drives the clamping block 221 to approach or move away from the fixed block 222 to clamp or release the single-material PE film. Since the single-material PE film has a certain width, in order to adapt to the width of the single-material PE film, the clamping block 221 and the fixed block 222 also have a certain width, and are greater than the width of the single-material PE film, thereby ensuring that the opening at the end of the single-material PE film can be completely closed.

[0031] Preferably, the first driving member 21 is a first cylinder, and the end of the piston rod of the first cylinder is connected to the clamping block 221. When clamping the single-material PE film, the first cylinder is started, and the piston rod of the first cylinder extends forward to push the clamping block 221 close to the fixed block 222 until the clamping block 221 and the fixed block 222 clamp the single-material PE film therebetween, thereby achieving the clamping of the single-material PE film. After an independent bag body is formed, the piston rod of the first cylinder retracts, driving the clamping block 221 away from the fixed block 222, thereby enabling the conveying unit 10 to continue to convey the single-material PE film downward, so as to achieve continuous segmentation of the single-material PE film into bags.

[0032] In order to ensure the stability of the movement of the clamping block 221, a guide unit 40 is provided to provide support for the movement of the clamping block 221. Figure 4 as well as Figure 5As shown, the guide unit 40 includes two guide rods 41 and two guide cylinders 42. The two guide cylinders 42 and the two guide rods 41 are respectively fixed to the two ends of the clamping block 221 along the width direction of the clamping block 221. When the first driving member 21 drives the clamping block 221 to move, the two guide cylinders 42 move along the corresponding guide rods 41, so that the clamping block 221 can always move along the second direction D2 to ensure that the sealing angle of the single-material PE film is consistent each time. Since the splitting unit 30 is connected to the clamping unit 20, the splitting unit 30 can also always keep moving along the second direction D2 during the movement of the clamping block 221, so that the angle of each cutting is consistent, thereby ensuring the quality of the independent bag body.

[0033] In a feasible implementation mode, referring to Figures 3 to 5 As shown, the second driving member 31 is a second cylinder, which is fixed on the clamping block 221, and the dividing member 32 is fixed on the piston rod end of the second cylinder. When the clamping block 221 moves, the second cylinder and the dividing member 32 are synchronously close to the single-material PE film along with the clamping block 221. After the clamping unit 20 completes the sealing of the single-material PE film, the second cylinder is started, and the piston rod of the second cylinder extends forward, pushing the dividing member 32 closer to the single-material PE film until the single-material PE film clamped by the clamping member 22 is cut at the lower end of the seal. After the cutting is completed, the piston rod of the second cylinder retracts, driving the dividing member 32 away from the single-material PE film. In order to ensure the smooth movement of the dividing member 32 and the effect of cutting the single-material PE film, two second cylinders are provided, and the piston rod ends of the two second cylinders are respectively connected to the opposite ends of the dividing member 32.

[0034] Reference Figure 5 As shown, the dividing piece 32 is a cutter, which is arranged on the clamping block 221 along the third direction D3, and the length of the cutter is adapted to the width of the single-material PE film to ensure that the cutter can cut the single-material PE film along the width direction of the single-material PE film. In other embodiments, the dividing piece 32 can adopt other structures or components that can cut the single-material PE film, which is not limited here.

[0035] Based on the above embodiments, the working process of the single-material PE film splitting into bags device of the present application is as follows:

[0036] The single-material PE film wound on the roll is transported to the clamping unit 20 under the action of the conveying unit 10. When the single-material PE film reaches between the clamping block 221 and the fixed block 222 and is transported a certain distance (the length of the independent bag body), the conveying unit 10 stops conveying the single-material PE film, and the first cylinder is started to push the clamping block 221 close to the fixed block 222 until it contacts the fixed block 222, and the single-material PE film is fixed between the clamping block 221 and the fixed block 222. The heat-sealing member 23 on the clamping block 221 seals the clamped portion of the single-material PE film. The single-material PE film is heated in position to seal the single-material PE film, and then the second cylinder is started to push the dividing piece 32 close to the single-material PE film to cut off the portion of the single-material PE film below the seal, and the cut portion forms an independent bag body. After the cutting is completed, the first cylinder and the second cylinder respectively drive the clamping block 221 and the dividing piece 32 away from the single-material PE film, and the conveying unit 10 continues to transport the single-material PE film downward, stops again after transporting a certain distance, and repeats the aforementioned clamping and cutting steps, thereby realizing the process of continuously sealing and dividing the single-material PE film into bags.

[0037] The above describes in detail the structure, features and effects of the utility model based on the embodiments shown in the drawings. The above is only a preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation shown in the drawings. Any changes made in accordance with the concept of the utility model, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and the drawings, should be within the protection scope of the utility model.
