[0004] In the above technical scheme, by setting a sliding component and a limit component and utilizing the functions of the sliding component and the limit component, the device provided by the utility model can effectively clamp packaging bags of different sizes. When sealing, the lower heating plate is mainly pressed downward by the upper heating plate to complete the sealing of the packaging bag between the upper heating plate and the lower heating plate. Therefore, the packaging bag needs to be placed horizontally. However, after the packaging bag is filled with plastic masterbatch, the plastic masterbatch in the packaging bag may easily leak out of the packaging bag when the packaging bag is placed horizontally, thereby affecting the sealing of the packaging bag.

[0018] like Figures 1 to 3 As shown, the utility model discloses a sealing device for improving the suture quality of a powder bag suture line, comprising a base 1, a conveying mechanism for conveying powder bags is arranged on the base 1, sealing pressing plates 2 are arranged above the base 1 and on both sides of the powder bag conveying path, a sealing area is formed between adjacent sealing pressing plates 2, the sealing area and the conveying path of the powder bag are on the same horizontal line, adjacent sealing pressing plates 2 move towards each other to complete the sealing of the powder bag, smoothing mechanisms are arranged on both sides of the sealing area, the smoothing mechanisms are used to smooth the sealing part of the powder bag, when the powder bag needs to be sealed, the powder bag can be placed vertically on the conveying mechanism, so as to prevent the plastic masterbatch in the powder bag from sliding toward the sealing part, thereby ensuring the formation quality of the powder bag suture line, and further ensuring the sealing quality of the powder bag, and through the smoothing mechanism, the sealing part of the powder bag can be smoothed before the powder bag enters the sealing pressing plate 2, so as to reduce wrinkles at the sealing part, thereby further ensuring the sealing quality of the powder bag.

[0019] In this embodiment, the sealing pressure plates 2 on both sides move toward each other to complete the sealing of the powder bag. The specific structure is that an extension plate 3 extending upward is provided on the base 1, and a connecting bin 4 is fixed on the inner side of the extension plate 3. A mounting cavity is provided in the connecting bin 4, and a slidable first connecting rod 5 and a second connecting rod 6 are provided in the mounting cavity. The first connecting rod 5 and the second connecting rod 6 extend to the outside of the mounting cavity as the proximal end and the distal end respectively. Therefore, after the sealing pressure plates 2 are fixed at the proximal end and the distal end respectively, a sealing area can be formed between the adjacent sealing pressure plates 2. A first connecting plate 7 and a second connecting plate 8 are provided in the mounting cavity. One end of the first connecting plate 7 is fixedly sleeved on the first connecting rod 5, and the other end is for the second connecting rod 6 to pass through. One end of the second connecting plate 8 is fixedly sleeved on the second connecting rod 6, and the other end is for the first connecting rod 5 to pass through. A transmission seat 9 is rotatably connected, and the first connecting plate 7 and the second connecting plate 8 are rotatably connected to the transmission seat 9 through a connecting rod 200 respectively. A cylinder 10 is provided at the bottom of the connecting bin 4, and the output end of the cylinder 10 extends into the mounting cavity and is rotatably connected to the transmission seat 9. Therefore, after the output end of the control cylinder 10 is extended and retracted, the transmission seat 9 can be driven to rotate. After the transmission seat 9 rotates, it can pull the first connecting rod 5 and the second connecting rod 6 to move toward or away from each other through the first connecting plate 7 and the second connecting plate 8 respectively, thereby driving the sealing pressure plates 2 on both sides to move toward each other to complete the sealing of the powder bag, wherein the sealing pressure plate 2 performs hot-melt sealing on the sealing portion of the powder bag by electric heating, which is a conventional technical means in the field of packaging bag sealing, so its principle and specific structure are not repeated here.

[0020] In this embodiment, the conveying mechanism is specifically a linear motor 11, and a downwardly recessed placement groove 111 is provided on the mover seat of the linear motor 11. The placement groove 111 is used to place the powder bag. The powder bag can be positioned by the set placement groove 111 to prevent the powder bag from falling from the mover seat when the linear motor 11 is conveying the powder bag.

[0021] In this embodiment, the extension plate 3 is arranged on both sides of the conveying mechanism, and the extension plates 3 are provided with extension parts 31 extending outward horizontally on both sides, so that the sealing part of the powder bag can be flattened when the package is sent to the sealing area during the reciprocating process of the linear motor 11, thereby improving the sealing efficiency of multiple powder bags;

[0022] The specific structure of the smoothing mechanism includes a support seat 121, which is fixed to the extension portion 31. A mounting groove 121a is provided in the support seat 121, and a slidable sliding rod 122 is provided in the mounting groove 121a. A spring 123 is provided between the connecting rod and the mounting groove 121a. One end of the spring 123 is fixed to the connecting rod, and the other end is fixed to the bottom of the mounting groove 121a. The connecting rod is located on a side away from the spring 123 and is rotatably connected to an extrusion wheel 124. By arranging the extension portions 31 on both sides of the extension plate 3, after the linear motor 11 passes the powder bag through the extrusion wheel 124, the thickness of the powder bag itself can squeeze the extrusion wheel 124 toward the mounting groove 121a, so that the spring 123 is compressed, and the reaction force generated by the compression of the spring 123 can act on the extrusion wheel 124, so that the extrusion wheels 124 on both sides can squeeze the passing powder bag, thereby completing the smoothing of the sealing portion of the powder bag, avoiding wrinkles at the sealing portion of the powder bag affecting the sealing of the bag by the sealing pressure plate 2.

[0023] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
