Abstract
Description
Technical Field
[0001] This utility model relates to the field of book printing technology, and in particular to an automatic plastic sealing device. Background Technology
[0002] With the rapid development of modern industrial production, the demand for packaging materials in various industries is constantly increasing, and the requirements for packaging efficiency and quality are also rising. Automatic sealing equipment, as a highly efficient and convenient packaging device, can meet the market's demand for high-quality and high-efficiency packaging. Especially in the fields of food, pharmaceuticals, cosmetics, and electronic products, the application of automatic sealing equipment has become an important means of enhancing product competitiveness; therefore, it is necessary to design an automatic sealing device.
[0003] To address this, patent CN221642886U discloses an automatic plastic sealing packaging device, relating to the field of packaging equipment technology. The device features longitudinally arranged columns fixedly connected to both sides of the top surface of the substrate. This solves the problem of low efficiency in existing plastic sealing processes, which rely on hot air blown from an air gun to melt the plastic. However, the lack of an effective rotation adjustment structure during blowing results in low efficiency. By incorporating a movable seat and a motor, the device, after clamping and limiting the workpiece at two clamping plates, simultaneously activates the motor mounted on the outside of the movable seat to drive the rotation of the mounting plate. The clamping plates then rotate the workpiece, achieving automated rotation adjustment. This facilitates subsequent automatic plastic sealing by activating a hot air assembly mounted on the top surface of the cover plate to supply air into the air duct.
[0004] When using the automatic sealing packaging equipment mentioned above, the outer sealing film of the product to be sealed is easily blown out of place by the wind during transportation, resulting in misalignment of the sealing film. Therefore, it is necessary to design an automatic sealing equipment. Utility Model Content
[0005] The purpose of this invention is to provide an automatic plastic sealing device to solve the defect that the outer plastic sealing film of the product to be sealed is easily blown out of place by the wind during transportation, resulting in misalignment of the plastic sealing film, when using existing automatic plastic sealing packaging equipment.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an automatic plastic sealing device, including a conveyor;
[0007] A thermoplastic assembly is provided on one side of the conveyor. The thermoplastic assembly includes a box, an inner cavity, a top groove, and a side groove. The box is located on one side of the conveyor. An inner cavity is opened inside the box. Side grooves are opened inside the boxes on both sides of the inner cavity. A top groove is opened inside the box at the top of the inner cavity.
[0008] The top of the inner cavity is provided with a blowing structure, and the top of the box is fixed with a heating structure;
[0009] The conveyor is equipped with a limit structure on the side away from the box.
[0010] Furthermore, the blowing structure includes a fan box, a drive motor, and a fan body. The fan box is fixed to the top of the housing, the fan body is disposed inside the fan box, and the drive motor is installed at the bottom of the fan box.
[0011] Furthermore, the bottom end of the fan body extends to the outside of the fan housing and is fixedly connected to the output end of the drive motor.
[0012] Furthermore, the heating structure includes a heating seat, a ventilation slot, a heating cavity, a heating wire, and an air duct. The heating seat is located at the top of the inner cavity, and a heating cavity is formed inside the heating seat. A heating wire is arranged inside the heating cavity. Ventilation slots are evenly formed inside the heating seat on both sides of the heating cavity. Air ducts are evenly fixed to the bottom of the heating seat below the ventilation slots.
[0013] Furthermore, the outer wall of the heating seat is fixedly connected to the interior of the housing, and the ventilation slots are evenly distributed inside the heating seat.
[0014] Furthermore, the heating wire has a spiral-shaped cross-section when viewed from above.
[0015] Furthermore, the limiting structure includes a bracket, an electric push rod, a support plate, a roller, and a guide rod. The bracket is evenly arranged on the side of the conveyor away from the box. An electric push rod is fixed to the top of each bracket, and a support plate is fixed to the top of each electric push rod. Rollers are evenly rotatably connected between adjacent support plates, and guide rods are slidably connected to both sides inside the support plate.
[0016] Furthermore, the rollers are evenly spaced on one side of the support plate, and the guide rods are symmetrically distributed on both sides of the support plate.
[0017] The automatic plastic sealing device provided by this utility model has the following advantages:
[0018] By setting a limiting structure, books already covered with plastic wrap are placed at the top of the conveyor. The conveyor will then gradually enter the box. When the books are conveyed to one side of the side trough, the rollers can hold and protect the plastic wrap on the outside of the books. This prevents the plastic wrap from being blown out of place by the air duct and affecting the sealing. The electric push rod can adjust the holding height of the rollers, which can be adjusted according to the thickness of the books, making it more versatile. This device has the functions of holding and protecting, and improves the convenience of using the automatic plastic wrapping equipment.
[0019] By setting up a heating structure and activating the heating wire, the heating wire generates heat. When the fan body rotates and blows air, the air passes through the heating wire and exchanges heat with the hot air around the heating wire. Then the hot air is blown to the bottom of the inner cavity to seal the book. This realizes that the device has the function of hot air sealing and improves the working efficiency of the automatic sealing equipment during use.
[0020] By incorporating a blowing structure and starting the drive motor, the rotation of the drive motor drives the fan body to rotate, which in turn blows air onto the heating structure. The hot air enters the inner cavity and heats and seals the liquid to be sealed, thus enabling the device to have a convenient blowing function and improving the ease of use of the automatic sealing equipment.

The bottom of the fan body 33 extends to the outside of the fan box 31 and is fixedly connected to the output end of the drive motor 32.
[0030] When an external power source is connected, the drive motor 32 is started. The rotation of the drive motor 32 will drive the fan body 33 to rotate. The rotation of the fan body 33 can blow air onto the heating structure 4. After the hot air enters the inner cavity 22, it can heat and seal the water to be sealed.
[0031] Reference Figures 2-5 A heating structure 4 is fixed to the top of the housing 21. The heating structure 4 includes a heating base 41, a ventilation groove 42, a heating cavity 43, a heating wire 44, and an air duct 45.
