[0002] The main function of packaging bags is to protect products from being squeezed, impacted, vibrated, and affected by temperature differences during transportation and storage, thereby maintaining the integrity and usability of the products. After the packaging bags are filled, they are sealed by a sealing machine.
[0003] When sealing bags are sealed by sealing machines on the market, the bag opening needs to be inserted into the sealing channel, and the packaging tape needs to pass through the sealing machine along the length of the sealing channel. During this process, the material inside the bag will continuously exert downward pressure on the bag, which can easily cause the bag to be stretched and deformed or even detach from the sealing channel during the sealing process. Utility Model Content
[0004] In view of this, the present invention provides a bag sealing device that can support the packaging bag during the sealing process through a synchronous support component, thereby reducing the possibility of the packaging bag being deformed by pressure or even the sealing machine detaching during the sealing process.

[0027] This utility model discloses a bag sealing device that can support the packaging bag during the sealing process through a synchronous support component, thereby reducing the possibility of the packaging bag being deformed by pressure or even the sealing machine detaching during the sealing process.
[0028] 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.
[0029] This disclosure provides a bag sealing device in exemplary embodiments, such as... Figure 1 As shown, Figure 1 This is a schematic diagram illustrating the structure of a bag sealing device according to an exemplary embodiment; Figure 2 This is illustrated according to an exemplary embodiment. Figure 1 The middle image is an enlarged view of part A, which indicates the position of the beveled surface; Figure 3 This is illustrated according to an exemplary embodiment. Figure 1 The middle view is an enlarged view of part B, which shows the structure of the synchronous support component. Figure 4 This is illustrated according to an exemplary embodiment. Figure 1 The middle section is an enlarged view showing part C of the support structure. The following section combines... Figures 1 to 4 To explain.
[0030] The specific embodiments described below are intended to help those skilled in the art understand this embodiment, but this embodiment is not limited to the specific embodiments described below.
[0031] Reference Figure 1 This disclosure provides an exemplary embodiment of a bag sealing device, the bag sealing device comprising:
[0032] Conveyor belt 1 is used to transfer materials from a first position to a second position;
[0033] Sealing machine 2 is fixed above conveyor belt 1 and located between the first position and the second position. Sealing machine 2 has a sealing channel 11 for the material to be sealed to pass through.
[0034] The synchronous support assembly 3 includes multiple rollers 31 distributed along the length of the conveyor belt 1 and located below the sealing channel 11, a connecting rod 32 rotatably connected to one end of the roller 31, a support rod 33 hinged to the connecting rod 32, and a support rod 34 detachably connected to the support rod 33. The rollers 31 are perpendicular to the transmission direction of the conveyor belt 1. The support rod 34 has multiple mounting positions 35 for fixing the support rod 33. When the support rod 33 is located in different mounting positions 35, the rollers 31 are set at different angles to the conveyor belt 1.
[0035] For example, refer to Figure 1 and Figure 2 The conveyor belt 1 is long and straight, positioned horizontally, with the first and second positions being its two ends. The side of the conveyor belt 1 is enclosed by a solid structure. The sealing machine 2 is fixed to the side of the conveyor belt 1, extending from its side above and towards one side of the conveyor belt 1. A sealing channel 11 is located on one side of the sealing machine 2 above the conveyor belt 1, with its length parallel to the length of the conveyor belt 1. The sealing machine 2 has a protective shell 21 extending from its top towards its side, with its edge extending to the top side of the sealing channel 11. The bottom side of the protective shell 21 has a beveled section 22 extending from the side of the protective shell 21 facing the roller 31 to the top edge of the sealing channel 11, i.e., the beveled section 22 is positioned diagonally downwards from the sealing channel 11. The protective shell 21 can increase the distance between the sealing channel 11 and the user by its own thickness, reducing the possibility of the user's fingers or other tools being inserted into the sealing channel 11. At the same time, the beveled surface 22 can expose the opening of the sealing channel 11 to the user's line of sight, making it easier for the user to understand the sealing process, thus balancing safety and ease of use.
[0036] Reference Figure 3 and Figure 4The support rod 34 is horizontally positioned and perpendicular to the length of the conveyor belt 1. One end of the support rod 34 is fixedly connected to the side wall of the sealing machine 2, and the other end extends above the conveyor belt 1, forming a gap between the support rod 34 and the conveyor belt 1. The connecting rod 32 is hinged to the end of the support rod 34 away from the sealing machine 2 and is inclined relative to the conveyor belt 1. The rotation axis of the connecting rod 32 is parallel to the length of the conveyor belt 1. The bottom end of the connecting rod 32 is hinged to the support rod 34, and the top end of the connecting rod 32 is rotatably connected to the roller body 31. The roller body 31 is coaxially arranged with the connecting rod 32, that is, the roller body 31 is inclined relative to the conveyor belt 1, and the top end of the roller body 31 extends towards the sealing machine 2 to below the sealing channel 11. The support rod 33 is inclined relative to the conveyor belt 1. The top end of the support rod 33 is hinged to the connecting rod 32, and the bottom end of the support rod 33 is inserted into the support rod 34. The rotation axis of the support rod 33 is set along the length of the conveyor belt 1, and the support rod 33 and the connecting rod 32 are set at an angle. The mounting position 35 includes a plurality of positioning holes opened on the support rod 34. The positioning holes are adapted to the support rod 33 and are distributed at intervals along a direction perpendicular to the conveyor belt 1. The opening direction of different positioning holes is different, so that the support rod 33 can be inserted into different positioning holes and the inclination angle of the connecting rod 32 connected to the roller 31 can be changed.
[0037] In this embodiment, each roller 31 corresponds to a connecting rod 32, a support rod 34 and a strut 33. There are multiple rollers 31 and they are distributed along the length of the conveyor belt 1. For example, the rollers 31 are distributed from one end of the sealing channel 11 to the other end of the sealing channel 11.
[0038] The rotatable connection between the connecting rod 32 and the roller 31 can be achieved by providing a spherical or frustum-shaped convex structure at the top of the connecting rod 32, and a groove adapted to the aforementioned convex structure inside the roller 31. The coaxial rotation and axial engagement between the connecting rod 32 and the roller 31 is a conventional arrangement in the prior art, and therefore not elaborated upon in this application. Additionally, in other embodiments, the roller 31 can be directly fitted onto the connecting rod 32 to achieve the same technical solution described in this application and achieve the same technical effect. That is, the axial engagement between the connecting rod 32 and the roller 31 is merely a means to improve stability in industrial production, and is not essential for achieving the technical solution described in this application.
[0039] In this embodiment, the packaging bag is supported by the roller 31. The rotating roller 31 can reduce the friction force on the packaging bag during the conveyor belt 1, so that the packaging bag can be smoothly conveyed with the conveyor belt 1. By installing the support rod 33 at different positions on the bracket 53, the angle of the roller 31 relative to the conveyor belt 1 can be changed, thereby adapting to packaging bags of different sizes or containing different objects.
[0040] In an exemplary embodiment of this disclosure, reference is made to Figure 1 and Figure 3 It also includes a synchronous belt 5 fixed on the side of the conveyor belt 1 facing away from the sealing machine 2. The material conveying surface of the synchronous belt 5 is set facing the sealing machine 2. The synchronous belt 5 and the roller body 31 are distributed at intervals. The material channel 4 is formed by the conveyor belt 1 exposed between the bottom ends of the synchronous belt 5 and the roller body 31.
[0041] For example, refer to Figure 3 and Figure 4 The synchronous belt 5 includes a drive pulley 54 and a driven pulley 51 that rotate synchronously with the conveyor belt 1, a belt 52 facing the sealing machine 2, and a bracket 53 for supporting the drive pulley 54 and the driven pulley 51. The bracket 53 is fixed to the top of the drive pulley 54 and the driven pulley 51. The axes of the drive pulley 54 and the driven pulley 51 are both vertically arranged, and the length direction of the belt 52 is parallel to the length direction of the conveyor belt 1. The bottom ends of the drive pulley 54 and the driven pulley 51 are coaxially fixed with support plates 55 extending outward. The solid part of the support plate 55 extending beyond the bottom edge of the drive pulley 54 (and the driven pulley 51) supports the belt 52, reducing the possibility of the belt 52 moving downward when the drive pulley 54 and the driven pulley 51 are vertically arranged.
[0042] The support bracket 53 is slidably connected to the conveyor belt 1. As previously described, the side of the conveyor belt 1 is a solid, enclosed structure. The support bracket 53 includes a support frame 532 fixed to the side wall of the conveyor belt 1 and a telescopic frame 531 slidably connected to the support frame 532. Taking the support bracket 53 related to the drive wheel 54 as an example: the support frame 532 is a hollow, horizontally placed U-shaped structure. Each support frame 532 corresponds to two telescopic frames 531. The two telescopic frames 531 are respectively inserted into both ends of the support frame 532, and the two telescopic frames 531 are vertically spaced apart. One end of the lower telescopic frame 531 is inserted into the interior of the support frame 532, and the other end is fixed to the side wall of the conveyor belt 1. One end of the higher telescopic frame 531 is inserted into the interior of the support frame 532, and the other end is fixed with a bearing 7, which can be a thrust bearing 7. The bearing 7 is coaxially and fixedly connected to the drive wheel 54. A fixing block 8 for connecting the shaft of the drive wheel 54 is fixed to the end of the aforementioned higher telescopic frame 531. That is, the shaft of the drive wheel 54 passes vertically through the bearing 7 and is fixedly connected to the fixing block 8. Bolts 6 are threaded onto the support frame 532, and two bolts 6 are present on the same support frame 532. The threaded end of the bolt 6 extends into the interior of the support frame 532, and by tightening the bolt 6, the threaded end of the bolt 6 can abut against the telescopic frame 531 inside the support frame 532. The two bolts 6 correspond to the two telescopic frames 531 on the same support frame 532. Similarly, the structure of the bracket 53 related to the driven wheel 51 is also the same, and will not be described further here. By loosening the bolts 6, the support frame 532 can drive the synchronous belt 5 to move relative to the conveyor belt 1, that is, from the third position close to the roller 31 on the side of the conveyor belt 1 to the fourth position away from the roller 31 on the side of the conveyor belt 1, thereby changing the width of the material channel 4.
[0043] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
