Description

Technical Field

[0001] This utility model relates to the field of packaging bag technology, specifically to a bag making machine unwinding mechanism. Background Technology

[0002] With the development of packaging technology, the variety of packaging products is constantly increasing, including some bag types with overlapping structure designs. To manufacture such overlapping bags, two feeding racks on the bag making machine are required. However, the number of feeding racks on existing bag making machines is fixed, which limits the number of overlapping bags that can be manufactured, thus affecting the production progress of the entire production line and increasing production costs. In view of this, a bag making machine unwinding mechanism is proposed. Utility Model Content

[0003] In view of the problems existing in the prior art, the purpose of this utility model is to provide a bag making machine unwinding mechanism that can realize the manufacturing of overlapping bags without the need for additional unwinding racks, thus saving costs.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a bag making machine unwinding mechanism, placed on a plane, includes an unwinding roll, a guiding mechanism, and an overlapping mechanism. A guide roller is arranged on the plane between the guiding mechanism and the overlapping mechanism. A cutting mechanism is arranged on the guiding mechanism. A roll of material is wound on the unwinding roll. The roll of material is unwound through the guiding mechanism, the guide roller, and the overlapping mechanism. The overlapping mechanism includes a stand and a controller. An output port is arranged on the stand. A correction roller is arranged on the side of the stand away from the guide roller. An electric push rod is connected to the end of the correction roller. The electric push rod is connected to the stand. The end of the correction roller near the electric push rod is higher than the end of the correction roller away from the electric push rod.

[0005] In some embodiments, the cutting mechanism includes two mounting brackets, both of which are connected to the guide mechanism. A mounting rod is provided between the two mounting brackets, and a knob is fixedly connected to each end of the mounting rod. An arc-shaped groove is provided on each of the two mounting brackets, and an insert rod is fixedly connected to each of the two knobs. The two insert rods are respectively connected to one of the arc-shaped grooves. A connecting frame is provided in the middle of the mounting rod, and a cutter is mounted on the connecting frame.

[0006] In some embodiments, a groove is provided at each end of the straightening roller, and the upright and the electric push rod are both connected to the straightening roller through the groove.

[0007] In some embodiments, an auxiliary component is provided on the side of the upright frame near the guide roller. The auxiliary component includes two mounting blocks, each of which is provided with a connecting rod, and an auxiliary roller is connected between the two connecting rods.

[0008] In summary, this utility model has the following beneficial effects:

[0009] This invention features an overlapping mechanism that uses a correction roller to overlap two rolls of material, thus enabling the manufacture of overlapping bags without the need for additional feeding racks. This effectively saves costs and improves production efficiency. Furthermore, the cutting mechanism allows the rolls to be cut as needed, enabling the entire large roll to be cut into two parts without the need for separate feeding racks, which is very convenient.

[0018] 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.

[0019] See Figure 1-7 A bag making machine unwinding mechanism is placed on a plane 7, including an unwinding roll 1, a guiding mechanism 2, and an overlapping mechanism 4. A guide roller 5 is arranged on the plane 7 between the guiding mechanism 2 and the overlapping mechanism 4. A cutting mechanism 3 is arranged on the guiding mechanism 2. A roll of material 6 is wound on the unwinding roll 1. The roll of material 6 is unwound through the guiding mechanism 2, the guide roller 5, and the overlapping mechanism 4. The overlapping mechanism 4 includes a stand 41 and a controller 43. An output port 42 is arranged on the stand 41. A correction roller 45 is arranged on the side of the stand 41 away from the guide roller 5. An electric push rod 44 is connected to the end of the correction roller 45. The electric push rod 44 is connected to the stand 41. The end of the correction roller 45 near the electric push rod 44 is higher than the end of the correction roller 45 away from the electric push rod 44. In use, the operator unwinds the roll 6 on the unwind roll 1 via the guide mechanism 2, guide roller 5, and the correction roller 45 of the overlapping mechanism 4. The roll 6 can be paper or film, but is not limited to these. During the unwinding process, when the roll 6 is a single large sheet, it is cut into two identical parts from the middle by the cutting mechanism 3 when it passes through the cutting mechanism 3. After the two cut parts of the roll 6 pass through the overlapping mechanism 4, the operator controls the electric push rod 44 via the controller 43 to move one end of the correction roller 45 upward. The entire device can be controlled by an existing intelligent program and operated using the controller 43. This causes the part of the two cut parts of the roll 6 closest to the electric push rod 44 to be lifted by the correction roller 45, so that the lifted part of the roll 6 overlaps with the other part during the unwinding process, as shown in the attached figure. Figure 6 As shown, the overlap range can be controlled by the height of the correction roller 45. When the roll 6 is initially divided into two parts, the operator controls the cutting mechanism 3 to stop cutting the roll 6 and the overlap can be achieved directly through the correction roller 45 of the overlap mechanism 4.

[0020] In some embodiments, the cutting mechanism 3 includes two mounting brackets 31, both of which are connected to the guide mechanism 2. A mounting rod 32 is provided between the two mounting brackets 31. A knob 33 is fixedly connected to each end of the mounting rod 32. An arc-shaped groove 311 is provided on each of the two mounting brackets 31, and an insertion hole is provided inside the arc-shaped groove 311. An insertion rod 331 is fixedly connected to each of the two knobs 33. The two insertion rods 331 are respectively connected to an arc-shaped groove 311. A connecting frame 34 is provided in the middle of the mounting rod 32, and a cutter 35 is mounted on the connecting frame 34. When the coil 6 is initially divided into two parts, the operator rotates the knob 33, which drives the mounting rod 32 to rotate, causing the mounting rod 32 to move the cutter 35 away from the coil 6. At the same time, the knob 33 moves the insertion rod 331 within the arc groove 311. After the knob 33 moves the mounting rod 32 and the cutter 35 away from the coil 6, the operator inserts the insertion rod 331 into the insertion hole for fixation, ensuring that the cutter 35 is away from the coil 6. If the coil 6 is a single large sheet, the knob 33 is then controlled to reset the insertion rod 331, and then the insertion rod 311 is inserted into the insertion hole for fixation. The operation is simple and convenient. The insertion rod 331 consists of a horizontal plate and a sliding rod, which can slide on the horizontal plate.

[0021] In some embodiments, a groove 451 is provided at each end of the straightening roller 45, and the upright frame 41 and the electric push rod 44 are both connected to the straightening roller 45 through the groove 451. When the operator controls the electric push rod 44 to move one end of the straightening roller 45, the electric push rod 44 will move on the groove 451. The groove 451 provides space for the straightening roller 45 to move, thereby ensuring that the movement of the straightening roller 45 is not restricted.

[0022] In some embodiments, an auxiliary component 46 is provided on the side of the upright 41 near the guide roller 5. The auxiliary component 46 includes two mounting blocks 461, each of which is provided with a connecting rod 462. An auxiliary roller 463 is connected between the two connecting rods 462. When the operator needs to fine-tune the overlap of the two rolls 6, the two mounting blocks 461 can be controlled to move up and down, as shown in the attached figure. Figure 5 As shown, both mounting blocks 461 are connected to the upright frame 41 via straight rods. By adjusting the mounting blocks 461 to move on the straight rods, the auxiliary roller 463 can be tilted, thereby fine-tuning the overlap of the coil 6. The principle of the auxiliary roller 463 is similar to that of the correction roller 45, and will not be elaborated further here.

[0023] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
