Description

Technical Field

[0001] This utility model relates to the field of plastic sealing electrical technology, specifically a heating device for a plastic sealing machine. Background Technology

[0002] A laminating machine is a device used to laminate paintings, charts, documents, cards, photos, etc. After purchasing one, a household can laminate items themselves. Currently, some laminating machines on the market use heating wires or heating tubes as a heat source, supplemented by an aluminum component as a whole. The heat source conducts heat to the aluminum component, which then conducts heat to the molding component, melting the molding film. Finally, the rear roller presses it together. Other products heat the rollers, which then melt and press the molding film together. Still others use a hot air heating system.

[0003] A hot air laminating machine, as disclosed in announcement number CN221476147U, includes a housing and an infeed roller assembly and an outlet roller assembly installed within the housing. The infeed roller assembly and the outlet roller assembly form a laminating path. The machine also includes an air outlet duct transversely positioned along the laminating path. An axially oriented air outlet is provided on the side wall of the air outlet duct, facing the laminating film passing through the laminating path. A heating element is installed inside the air outlet duct to heat the air within it. The machine also includes a fan connected to the air outlet duct, which pumps air into the duct, enabling more efficient and rapid heating. However, existing models have the following drawbacks in use:

[0004] (1) Existing laminating machines do not have a contact structure, which makes them unsuitable for plastic seals of different sizes and thicknesses, greatly reducing the applicability of laminating machines and easily causing the products inside the plastic seals to deform due to excessive compression during the conveying process.

[0005] (2) The air inlet of the existing laminating machine is not equipped with a filter screen, which causes impurities or small solid particles sucked in by the fan during operation to damage the fan impeller and reduce the service life of the heating device in the laminating machine.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0030] Example 1:

[0031] like Figures 1 to 6 As shown, this embodiment proposes a heating device for a laminating machine, including a laminating machine housing 1, abutment structures 5, and an air supply housing 6. Support plates 2 are fixedly connected to both sides of the interior of the laminating machine housing 1. Each of the two support plates 2 has three equidistant through-cavities 3. The front and rear sides of the six through-cavities 3 are respectively provided with sliding grooves 4. A roller feed group 15 is provided at the front of the opposite side of the two support plates 2, and a roller discharge group 16 is provided at the rear of the opposite side of the two support plates 2. An air outlet pipe 17 is provided on the opposite side of the roller discharge group 16 and the roller feed group 15. A heating mesh 20 is provided inside the air outlet pipe 17. There are six sets of abutment structures 5, each set located inside one of the through-cavities 3. The air supply housing 6 is located between one of the support plates 2 and the laminating machine housing 1, and a fan 7 is provided on one side of the interior of the air supply housing 6. On the other side, there is an inner cavity 8, inside which is a removable filter screen 10. Between each pair of opposing abutment structures 5, there is an inlet roller group 15, an outlet pipe 17, and an outlet roller group 16. The inlet roller group 15 includes a conveying roller, a rotating shaft, and an electric motor. The rotating shaft passes through the inside of the conveying roller. One end of the rotating shaft is connected to a movable seat 503 in one of the abutment structures 5 by a bearing. The other end passes through the movable seat 503 of the other opposing abutment structure 5 and is fixedly connected to an electric motor. A fixing plate is fixedly connected to the bottom of the electric motor. The movable seat 503 is fixedly connected to the side of the fixing plate near the rotating shaft. The structure of the outlet roller group 16 is exactly the same as that of the inlet roller group 15. The top of the laminating machine housing 1 is equipped with a control panel. The electric motor is electrically connected to the control panel, and the fan 7 is electrically connected to the control panel.

[0032] Example 2:

[0033] The following describes the scheme in Embodiment 1 in more detail with reference to the specific working method. Each set of abutment structure 5 includes a damping rod 501 and a movable seat 503. One end of the damping rod 501 is fixedly connected to the inner wall of the cavity 3, and the other end is fixedly connected to the movable seat 503. The front and rear sides of the movable seat 503 are fixedly connected to sliders 504. The outer wall of the damping rod 501 is sleeved with a spring 502. The two sliders 504 are respectively adapted to and connected to the slide groove 4.

[0034] The device is equipped with six sets of abutment structures 5. Between each pair of abutment structures 5, there are respectively an inlet roller group 15, an outlet pipe 17, and an outlet roller group 16. The moving seat 503 is pushed by the cooperation of the damping rod 501 and the spring 502 to move under the guidance of the slide groove 4. This makes the inlet roller group 15, the outlet pipe 17, and the outlet roller group 16 more suitable for plastic seals of different sizes and thicknesses. It avoids excessive compression of the product inside the plastic seal during the conveying process, which would cause product deformation. This greatly increases the applicability of this utility model.

[0035] Example 3:

[0036] The following describes the solution in Embodiment 2 in detail with reference to the specific working method: Fixed shafts 19 are respectively installed on both sides of the interior of the air outlet pipe 17. One end of each fixed shaft 19 is fixedly connected to the movable seat 503, and the other end is fixedly connected to the heating grid 20 through the air outlet pipe 17. The outer wall of the air outlet pipe 17 is provided with several equidistant air outlet holes 18. The heating grid 20 is cylindrical in shape and hollow inside. The air outlet pipe 17 is connected to the fixed shaft 19 by bearings. The heating grid 20 is electrically connected to the control panel. The air outlet pipe 17 is made of heat-insulating pipe.

[0037] The plastic sealant is heated by the fan 7, heating grid 20 and air outlet 17. It is initially pressed by the air outlet 17 and then further pressed by the conveying roller in the roller group 16. The plastic sealant film is melted and pressed, and then directly abutted against the top of the plastic sealant by the air outlet 17 for heating. This ensures uniform heating and increases heat transfer efficiency, thereby improving the sealing efficiency.

[0038] Example 4:

[0039] The following describes the solution in Embodiment 3 in more detail with reference to the specific working method: The inner cavity 8 is provided with two sliding grooves 9 on both sides. The front and rear sides of the filter screen 10 are fixedly connected with two sliders 11. The top of the filter screen 10 is fixedly connected with a handle 12. The two sliders 11 are respectively adapted to the sliding grooves 9. The air supply housing 6 is provided with an air supply pipe 21 on the side near the support plate 2. One end of the air supply pipe 21 is inserted into the air supply housing 6, and the other end passes through the movable seat 503 and the fixed shaft 19 in sequence and extends into the interior of the heating net 20.

[0040] A removable filter screen 10 is installed at the air inlet of the fan 7. The filter screen 10 can filter impurities or small solid particles sucked in by the fan 7 during operation, thereby increasing the service life of the fan 7. The filter screen 10 can be removed for cleaning by lifting the handle 12 upward through the cooperation of the slide groove 2 9 and the slider 2 11. The structure is simple, the operation is convenient, and the filtration efficiency is increased, thereby improving the heating efficiency.
