[0001] The utility model relates to the technical field of sealing machines, in particular to a wide-edge plastic bag sealing machine which is easy to adjust. Background Art

[0002] Plastic bags are a common daily necessity used to hold other items. They can be found in supermarkets, traditional markets, department stores, warehouses, garbage dumps, etc. Plastic bags are made of thin and flammable plastic film. They are widely used because of their low cost, extremely light weight, large capacity, and easy storage.

[0003] The prior art patent (patent number: 201920670414.3, patent name: a plastic bag sealing machine that is easy to adjust) is provided with a primary thermal wire, a pressure plate and a secondary thermal wire. The primary thermal wire and the secondary thermal wire are brought into contact through the pressure plate, so that the opening of the plastic bag begins to melt and adhere when heated, thereby achieving the sealing of the plastic bag.

[0004] The defects existing in the above patent are as follows: the above device makes two thermal wires contact through a pressure plate to seal the plastic bag, but when the plastic bag is melted and sealed, the staff is required to press the pressure plate all the time to prevent the pressure plate from moving up under the action of the spring, but when a large number of plastic bags are sealed, the staff is required to press the pressure plate continuously, which will cause muscle fatigue in the arms of the staff and make the staff feel tired. At the same time, when the plastic bag is melted, a part of it will adhere to the surface of the thermal wire. After multiple sealing of the plastic bag, more and more solution will be used to adhere to the surface of the thermal wire, which will reduce the effect of sealing the plastic bag.

[0031] A further advantage of adopting the above method is that when the above device is used to seal a large number of plastic bags, the staff does not need to continuously press the rotating pressure plate 2, thereby avoiding muscle fatigue in the staff's arms and further avoiding fatigue for the staff.

[0032] Embodiment 2 proposed based on Embodiment 1:

[0033] Reference Figure 4-7 A wide-edge plastic bag sealing machine that is easy to adjust includes a slide groove at one end of an operating table 1, a round tube is slidably connected in the slide groove, a connecting tube 202 is fixedly connected to one end of a rotating pressure plate 2, a connecting rod 4 is rotatably connected between the connecting tube 202 and the round tube, a moving tube 5 is slidably connected in the slide groove, and a connecting clamp 501 is connected between the moving tube 5 and the round tube.

[0034] Furthermore, an L-shaped movable plate 6 is fixedly connected to the surface of the movable tube 5, and a cleaning plate 601 which is fitted with the placement table 11 is fixedly connected to the bottom end of the L-shaped movable plate 6, and a scraping groove which is fitted with the heating rod 12 and the arc-shaped placement frame 1201 is provided at one end of the cleaning plate 601 (the cleaning plate 601 and the scraping groove can clean the solution on the surface of the heating rod 12), and a guide plate 602 is fixedly connected to one end of the cleaning plate 601 on both sides of the scraping groove (the guide plate 602 allows the cleaning plate 601 to keep the solution in the middle position when cleaning the heating rod 12), and a receiving groove for accommodating the L-shaped movable plate 6 is provided at the bottom end of the rotating pressing plate 2.

[0035] It should be noted that: one end of the operating table 1 is fixedly connected to a fixed plate 7, a telescopic tube 8 is arranged above the fixed plate 7, one end of the operating table 1 is fixedly connected to a plug tube rotatably connected to the telescopic tube 8, the top of the telescopic tube 8 is fixedly connected to a connecting plate 9, a spring 801 is connected between the fixed plate 7 and the connecting plate 9, the top of the connecting plate 9 is fixedly connected to a connecting piece 901, and one end of the rotating pressure plate 2 is fixedly connected to an L-shaped rotating plate 201 rotatably connected to the connecting piece 901.

[0036] It is worth noting that: a mounting groove is provided at one end of the operating table 1 , a collecting box 3 is installed in the mounting groove (the collecting box 3 collects the solution scraped off the surface of the heating rod 12 ), and a handle 301 is fixedly connected to one end of the collecting box 3 .

[0037] A further benefit of adopting the above method is that the above device cleans the solution adhering to the surface of the heating rod 12 when the plastic bag is melted, thereby avoiding the solution adhering to the heating rod 12 and thus avoiding affecting the sealing effect of the plastic bag.

[0038] The utility model is used as follows: when it is necessary to seal the plastic bag, the staff starts the heating rod 12 through the switch to preheat the heating rod 12, and then the staff first rotates the rotating pressing plate 2 to make the rotating pressing plate 2 move down a distance, and drives the L-shaped moving plate 6 and the cleaning plate 601 to move to the other side of the heating rod 12 through the connecting rod 4, and then the staff places the plastic bag on the placing table 11, and places the position of the plastic bag that needs to be sealed on the heating rod 12, and then the staff continues to rotate the rotating pressing plate 2 to make the rotating pressing plate 2 rotate to contact with the placing table 11, press the plastic bag, so that the position of the plastic bag that needs to be sealed is melted by the heating rod 12, and then seals it;

[0039] When the rotating pressure plate 2 rotates to contact the placement table 11, the L-shaped clamping plate 203 will drive the triangular block 204 to push the triangular clamping block 1002 and the rotating block 1001 to rotate. When the triangular block 204 is separated from the triangular clamping block 1002, the coil spring 1003 will drive the rotating block 1001 and the triangular clamping block 1002 to reset, and block and limit the triangular block 204 through the triangular clamping block 1002, thereby preventing the spring 801 from driving the rotating pressure plate 2 to rotate. When the above-mentioned device is used to seal a large number of plastic bags, there is no need for the staff to continuously press the rotating pressure plate 2, thereby avoiding muscle fatigue in the arms of the staff, and thus avoiding a feeling of fatigue for the staff.

[0040] When the plastic bag is sealed, the staff rotates the rotating block 1001 (while the staff rotates the rotating block 1001, the staff holds the plastic bag, and when the rotating pressing plate 2 rotates, the staff takes out the plastic bag), so that the spring 801 drives the rotating pressing plate 2 to rotate. When the rotating pressing plate 2 rotates, it drives the connecting rod 4 to move. The movement of the connecting rod 4 drives the moving tube 5 and the L-shaped moving plate 6 to move, thereby driving the cleaning plate 601 and the guide plate 602 to move, and the solution remaining on the heating rod 12 is scraped off and scraped into the collecting box 3. The above-mentioned device cleans the solution that adheres to the surface of the heating rod 12 when the plastic bag is melted, thereby avoiding the solution from adhering to the heating rod 12, thereby avoiding affecting the sealing effect of the plastic bag.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
