Description

Technical Field

[0001] The utility model relates to the technical field of sealing plates of packaging machines, in particular to an adjustable movable sealing plate for packaging machines. Background Art

[0002] Packaging bags refer to bags used to package various supplies, making it convenient to transport and store goods during the production and circulation process. They are widely used in daily life and industrial production. After the packaging bags are packaged, the sealing plate of the packaging machine needs to be used to heat-seal the bag opening.

[0003] When heat-sealing existing packaging bags, the bag opening needs to be manually placed between two heat-sealing plates, and then the heat-sealing plates heat-seal the bag opening. If the bag opening is not manually tightened during this process, the bag opening is prone to wrinkles when the heat-sealing plates clamp and heat-seal the bag opening, resulting in incomplete heat sealing and the presence of gaps. If the bag opening is tightened manually, it is easy to cause burns if the operation is not standardized. Utility Model Content

[0004] (1) Purpose of the utility model

[0005] In view of this, the purpose of the present invention is to propose an adjustable movable sealing plate for a packaging machine. The technical problem to be solved is that when the heat sealing plate heat seals the bag opening, if the bag opening is not manually tightened, the bag opening is prone to wrinkles when the heat sealing plate clamps and heat seals the bag opening, resulting in incomplete heat sealing and the presence of gaps. If the bag opening is tightened manually, burns may be easily caused if the operation is not standardized.

[0024] Specifically, the heat sealing mechanism includes two movable plates 12 arranged in the U-shaped frame 4, and a heat sealing plate 13 is installed on the side where the two movable plates 12 are close to each other, and a hydraulic cylinder 2 14 is installed on the two side plates of the U-shaped frame 4, and the extended end of the hydraulic cylinder 2 14 is fixed to the corresponding movable plate 12, and two guide rods 15 are fixed on the side where the two movable plates 12 are away from each other, and the guide rods 15 pass through the U-shaped frame 4 and are slidably connected to the U-shaped frame 4.

[0025] When the bag opening of the packaging bag needs to be heat-sealed, the hydraulic cylinder 1 5 is first extended to drive the U-shaped frame 4 to move downward. When the bag opening of the packaging bag is located in the U-shaped frame 4, the hydraulic cylinder 2 14 is extended to drive the movable plate 12 and the heat-sealing plate 13 to move closer to each other, so that the two heat-sealing plates 13 heat-seal the bag opening of the packaging bag.

[0026] It should be noted that the hydraulic cylinder 1 5, the hydraulic cylinder 2 14 and the heat sealing plate 13 are all conventional equipment purchased on the market and well known to those skilled in the art. The models can be selected or customized according to actual needs. In this patent, we only use them and do not improve their structure and function. For those skilled in the art, their setting method, installation method and electrical connection method only need to be debugged and operated according to the requirements of their instruction manual, and will not be described in detail here. In addition, the hydraulic cylinder 1 5, the hydraulic cylinder 2 14 and the heat sealing plate 13 are all provided with corresponding control switches. The installation position of the control switch is selected according to actual use requirements to facilitate the operator to operate and control.

[0027] In addition, the movable sleeve 6 is internally threadedly connected to a screw rod 11 , and one end of the screw rod 11 extending into the movable sleeve 6 is rotatably connected to a resisting plate 10 , which can be tightly pressed against the bracket 2 .

[0029] When the packaging bag is full of items and the bag opening of the packaging bag needs to be heat-sealed, the concave plate 19 is first moved close to the rectangular frame 16. When the concave plate 19 moves, the rotating rod 23 is driven to rotate. When the rotating rod 23 rotates, the splint 9 is driven to move, so that the two splints 9 move away from each other. At this time, when the two splints 9 move away from each other, the spring 18 is compressed. When the distance between the concave plate 19 and the cylinder 21 is greater than the length of the positioning rod 20, the positioning rod 20 is rotated to rotate it to face the cylinder 21, and then the concave plate 19 is supported, but no force is applied to the concave plate 19 in the direction of the rectangular frame 16. At this time, the positioning rod 2 is pressed against the cylinder 21 under the rebound force of the spring 18. 0 is embedded in the cylinder 21, that is, the concave plate 19 is fixed, so that the two clamping plates 9 are fixed. At this time, there is a large gap between the two clamping plates 9. Then, after the packaging bag is placed on the bottom plate 1, the bag opening of the packaging bag is placed between the two clamping plates 9. Then, the positioning rod 20 is moved out of the cylinder 21. At this time, the two clamping plates 9 are driven close to each other under the rebound force of the spring 18, so that the clamping plates 9 clamp the bag opening of the packaging bag, thereby facilitating heat sealing of the packaging bag. During heat sealing, there is no need to manually tighten the bag opening, which will not cause burns. Moreover, the bag opening is tightened and then clamped, so that no wrinkles or gaps will appear after heat sealing.
