Technical Field
[0001] This utility model relates to the field of pearl cotton bag production technology, specifically a pearl cotton bag folding and sealing device. Background Technology
[0002] Pearl cotton bags, also known as EPE bags, are full names for EPE pearl cotton laminated bags. Plain pearl cotton material is easy to break. Adding a layer of PE film can increase tensile strength and tear resistance, and better protect the product. Due to its good cushioning, heat insulation and waterproof characteristics, it is widely used in the packaging of many fields such as electronics, electrical appliances, handicrafts, food, and fruit. However, after the pearl cotton is cut, it is cut again to form small bag pieces. After folding, the two sides of the bag are heat-sealed.
[0003] However, the existing folding and sealing structure of pearl cotton bags still has some problems in use:
[0004] First, when the existing equipment seals the edges of pearl cotton bags, the position of the heat sealing knife is generally fixed. The fixed position of the heat sealing knife cannot be adapted to the heat sealing of pearl cotton bags of different specifications, so it is impossible to accurately heat seal the pearl cotton bags according to the actual situation.
[0005] Secondly, the current method of folding pearl cotton is generally done manually. This manual folding method is inefficient, and the pearl cotton may shift during the folding process, resulting in inaccurate size and uneven edges of the folded pearl cotton bag. Utility Model Content

[0008] Preferably, the folding mechanism includes symmetrically distributed positioning frames, which are symmetrically fixedly installed on the upper surface of the workbench. A DC motor is fixedly installed on one side of one of the positioning frames. The output end of the DC motor passes through the positioning frame and is fixedly connected to a central shaft. The end of the central shaft facing away from the output end of the DC motor is damped and rotatably connected to the inner cavity of the other positioning frame. A connecting seat is fixedly sleeved parallel to the outer surface of the central shaft. A first guide plate is fixedly connected to one side of the connecting seat. A second guide plate that works in conjunction with the first guide plate is fixedly installed on the upper surface of the workbench.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0010] 1. This application uses an adjustable sealing mechanism to allow for flexible adjustment of the heat sealing knife position on the pearl cotton bag to be sealed according to actual needs, so as to accurately heat seal the pearl cotton bag and improve the heat sealing effect of the device.

[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] Example: Figure 1-4 As shown, this utility model provides a folding and sealing device for pearl cotton bags, including a workbench 1. The upper surface of the workbench 1 is provided with a folding mechanism 3, which facilitates the quick and efficient folding of pearl cotton. A rectangular groove 4 is provided on one side of the workbench 1, and a sealing mechanism 2 is provided inside the rectangular groove 4, which can seal the pearl cotton bag at a specific position to ensure the accuracy of the sealing position.
[0020] The edge-sealing mechanism 2 includes a servo motor 23, which is fixedly installed on one side of the workbench 1. A first support 24 for use with the servo motor 23 is fixedly installed on one side of the workbench 1. The servo motor 23 is fixedly installed on the upper surface of the first support 24, which provides a stable installation position for the servo motor 23. The output end of the servo motor 23 passes through the workbench 1 and is fixedly connected to a screw 27. When the servo motor 23 rotates, it can drive the screw 27 to rotate. The end of the screw 27 facing away from the output end of the servo motor 23 is rotatably connected to the rectangular groove 4 to ensure the smoothness of the screw 27's rotation. A slider 25 is threaded on the outer surface of the screw 27. When the screw 27 rotates, the slider 25 can move along the axial direction of the screw 27. The slider 25 is slidably connected to the rectangular groove 4, which restricts the direction of movement of the slider 25, allowing it to move only along the axial direction of the screw 27.
[0021] A support frame 26 is fixedly connected to one side of the slider 25, facilitating the movement of the slider 25 to move the support frame 26 and adjust the position of the heat sealing knife body 22 to adapt to the sealing requirements of different sizes of pearl cotton bags. A cylinder 28 is fixedly connected to the upper surface of the support frame 26. The output end of the cylinder 28 passes through the support frame 26 and is fixedly connected to the knife holder 21. The extension and retraction of the cylinder 28 can control the raising and lowering of the knife holder 21. The cross-sectional shape of the knife holder 21 is inverted U-shaped. The inverted U-shaped design of the knife holder 21 allows for better installation and fixation. The heat-sealing knife body 22 is slidably connected to one side of the knife holder 21 and one side of the support frame 26, ensuring the stability of the knife holder 21 during the lifting process. The heat-sealing knife body 22 is fixedly installed inside the knife holder 21. Specifically, the heat-sealing knife body 22 is a JC-RF series heat-sealing knife produced by Wenzhou Jincheng Machinery Co., Ltd. The heat-sealing knife body 22 contains a heating element, which facilitates the movement of the knife holder 21 to move the heat-sealing knife body 22 to fit tightly against the pearl cotton bag, so as to perform a heat-sealing operation on the pearl cotton bag and achieve the sealing of the pearl cotton bag.
[0022] The folding mechanism 3 includes symmetrically distributed positioning frames 32, which are symmetrically fixedly installed on the upper surface of the workbench 1. A DC motor 35 is fixedly installed on one side of one of the positioning frames 32, and a second support 36 for use with the DC motor 35 is fixedly installed on one side of the other positioning frame 32. The DC motor 35 is fixedly installed on the upper surface of the second support 36, which provides a stable mounting position for the DC motor 35. The output end of the DC motor 35 passes through its positioning frame 32 and is fixedly connected to a central shaft 34. When the DC motor 35 rotates, it can drive the central shaft 34 to rotate. The end of the central shaft 34 facing away from the output end of the DC motor 35 is damped and rotatably connected to the inner cavity of the other positioning frame 32, ensuring the stability of the rotation of the central shaft 34. This makes the folding mechanism 3 more stable during operation and improves the accuracy of folding pearl cotton.
[0023] A connecting seat 38 is fixedly sleeved parallel to the outer surface of the central shaft 34. The connecting seat 38 can rotate with the rotation of the central shaft 34. A first guide plate 31 is fixedly connected to one side of the connecting seat 38, facilitating the rotation of the connecting seat 38 and the first guide plate 31. A second guide plate 33 is fixedly installed on the upper surface of the workbench 1 to cooperate with the first guide plate 31. The second guide plate 33 and the first guide plate 31 work together to guide and fold the pearl cotton. All guide plates 33 are vacuum adsorption plates. The first guide plate 31 and the second guide plate 33 are specifically YM-3000 vacuum adsorption platforms manufactured by Yinmei Precision Industry. They can adsorb pearl cotton through vacuum, keeping it stable during folding and preventing the pearl cotton from shifting its position. This effectively improves the accuracy of the size of the folded pearl cotton bag and the neatness of its edges. The upper surface of the second guide plate 33 is provided with a slot 37 that is used in conjunction with the connecting seat 38. The design of the slot 37 prevents the second guide plate 33 from affecting the rotation of the connecting seat 38.
[0024] Working principle: At this time, the folding mechanism 3 and the sealing mechanism 2 are in the initial standby state. First, the pearl cotton is placed at a suitable position on the upper surface of the first guide plate 31 and the second guide plate 33 in the folding mechanism 3. The pearl cotton is stably adsorbed on the first guide plate 31 and the second guide plate 33 by vacuum adsorption.
[0025] Then, the DC motor 35 is started. The output end of the DC motor 35 drives the central shaft 34 to rotate. The connecting seat 38 rotates together with the central shaft 34. The first guide plate 31 connected to one side of the connecting seat 38 rotates around the central shaft 34. During the rotation of the first guide plate 31, the connecting seat 38 moves along the slot 37 opened on the upper surface of the second guide plate 33, so that the pearl cotton is accurately folded under the action of the two guide plates, effectively replacing manual folding and ensuring that the folded pearl cotton bag is accurate in size and neat in edge.
[0026] According to the specifications of the pearl cotton bag to be sealed, the servo motor 23 in the sealing mechanism 2 is started. The output end of the servo motor 23 drives the screw 27 to rotate. The rotation of the screw 27 drives the slider 25 to slide in the rectangular groove 4. The support frame 26 will move with the slider 25, thereby driving the cylinder 28, the knife holder 21 and the heat sealing knife body 22 installed on the support frame 26 to move to the appropriate position to meet the sealing requirements of pearl cotton bags of different specifications.
[0027] When the heat sealing knife body 22 moves to a suitable position under the folded pearl cotton bag, the cylinder 28 is activated. The output end of the cylinder 28 pushes the knife holder 21 down, so that the heat sealing knife body 22 heat seals the edge of the pearl cotton bag, completing the edge sealing operation.
[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
