Description

Technical Field

[0001] This utility model relates to the field of heat sealing machine technology, and more specifically, to an energy-saving and efficient plastic film heat sealing machine. Background Technology

[0002] Heat sealing machines are used for sealing the surfaces of soft leather and plastics, as well as for sealing plastic packaging. The sealing of plastic films by heat sealing machines requires a certain temperature. Overheating or underheating, or insufficient time, will cause the plastic film to deform. Generally, if the plastic film is not separated in time after heat sealing, the heat sealing time will be too long, resulting in wrinkles in the plastic film and quality problems.

[0003] To address the aforementioned issues, patent document publication number CN212949255U discloses a plastic film heat sealing machine, comprising an operating table, a pressing unit, and a rebound unit. The operating table has a side plate on one side, with second bolts at both ends. These second bolts pass through through holes at both ends of the side plate and are threadedly connected to the top of the operating table. A fixing plate is located on the top of the side plate, with first bolts at both ends of one side of the fixing plate. These first bolts pass through through holes on one side of the fixing plate and are threadedly connected to the side plate. A rectangular groove is formed on the top of the operating table, and a heating wire is located at the bottom inner side of the rectangular groove. The rectangular groove is fixedly connected to the heating wire.

[0004] The above-mentioned device is easy to operate, has a good heat-sealing effect, and is convenient for replacing the heat-sealed residue. However, during use, because the fixed platform is located at both ends of the operating table and is fixed, although it is convenient to replace the rollers, it can only fix plastic films of a fixed width. Since different types of plastic films have different widths, it has a great limitation. Furthermore, since the rollers are located at both ends of the operating table, as the plastic film is unwound from the rear end, it is easy for the plastic film to come into contact with the edges and corners of the operating table, thereby causing wear on the plastic film and affecting its quality. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, the present invention provides an energy-saving and efficient plastic film heat sealing machine. This addresses the limitations of existing machines where the fixed platform is located at both ends of the operating table and is fixed in place. While this facilitates roller replacement, it only allows for fixing plastic films of a fixed width. Since different types of plastic films have different widths, this limitation is significant. Furthermore, with the rollers located at both ends of the operating table, the plastic film easily comes into contact with the edges and corners of the operating table after unwinding, causing wear and affecting the quality of the plastic film.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an energy-saving and efficient plastic film heat sealing machine, including a workbench, with fixed devices movably installed at both ends inside the workbench, a support component fixedly installed on the top of the fixed device, a heat sealing machine body fixedly installed on the top of the workbench, and a buffer device fixedly installed at one end of the top of the workbench.

[0007] The workbench includes an operating table, the inside of which is provided with a sliding groove, one end of the top of which is provided with a moving groove, and the side of which is provided with a rotating hole.

[0008] The fixing device includes a counter-rotating screw, which is rotatably installed inside a rotating hole. A rotating wheel is fixedly installed on the side of the counter-rotating screw. Moving plates are threadedly installed on the outer surfaces of both ends of the counter-rotating screw. The moving plates are slidably installed inside a sliding groove. Limiting plates are fixedly installed on both ends of the moving plates. A rotating handle is rotatably installed on the side of one end of the moving plate. An unwinding roller shaft is embedded inside the limiting plate.

[0009] The support assembly includes a support block, which is fixedly installed at one end of the top of the movable plate and slidably installed inside the movable groove. A limit block is fixedly installed at the upper end of the side of the support block, and a support shaft is fixedly installed on the side of the limit block. A support roller is movably sleeved on the outer surface of the support shaft.

[0010] The buffer device includes a support frame, which is fixedly installed at one end of the top of the operating table. A lifting groove is provided on the side of the support frame. Limiting rods are movably sleeved at both ends inside the support frame. A connecting frame is fixedly installed at the bottom of the limiting rods. A pressing spring is movably sleeved on the outer surface of the limiting rods. A pressing roller is rotatably installed at the bottom of the connecting frame. A positioning block is fixedly installed on the side of the connecting frame. The positioning block is slidably installed inside the lifting groove. The pressing spring is movably installed between the support frame and the connecting frame.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] In the above scheme, the rotation of the opposite screw causes the moving plate to move in opposite directions or in the same direction inside the sliding groove, thereby driving the limiting plate to move. This facilitates the installation of the unwinding roller shaft and can adapt to unwinding roller shafts of different lengths, thus adapting to plastic films of different widths. This makes the device more flexible, less limited, and improves its applicability.

[0013] The plastic film is pressed by the pressure spring to unfold it. After being wound up in the existing way, during the heat sealing process, the pressure roller assists in unfolding the plastic film while the support roller assists in moving the plastic film to cushion it. At the same time, the support roller supports the plastic film to prevent it from contacting the edges of the worktable and causing wear, thereby improving the heat sealing quality and overall quality of the plastic film.

[0020] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0021] As attached Figure 1 To be continued Figure 5 The present invention provides an energy-saving and efficient plastic film heat sealing machine, including a workbench 1, with fixing devices 2 movably installed at both ends inside the workbench 1, a support component 3 fixedly installed on the top of the fixing device 2, a heat sealing machine body 4 fixedly installed on the top of the workbench 1, and a buffer device 5 fixedly installed at one end of the top of the workbench 1.

[0022] The workbench 1 includes an operating table 11, with a sliding groove 12 inside the operating table 11, a moving groove 13 at one end of the top of the operating table 11, and a rotating hole 14 on the side of the operating table 11.

[0023] The fixing device 2 includes a counter-rotating screw 21, which is rotatably installed inside the rotating hole 14. A rotating wheel 22 is fixedly installed on the side of the counter-rotating screw 21. Moving plates 23 are threadedly installed on the outer surfaces of both ends of the counter-rotating screw 21. The moving plates 23 are slidably installed inside the sliding groove 12. Limiting plates 24 are fixedly installed on both ends of the moving plates 23. A rotating handle 26 is rotatably installed on the side of one end of the moving plates 23. An unwinding roller shaft 25 is embedded inside the limiting plate 24. The limiting plate 24 is set so that the inside of the limiting plate 24 has a hole corresponding to the unwinding roller shaft 25. By rotating the counter-rotating screw 21, the limiting plate 24 moves in opposite directions, directly placing the unwinding roller shaft 25 in the hole inside the limiting plate 24, thereby facilitating the installation of the unwinding roller shaft 25.

[0024] The support component 3 includes a support block 31, which is fixedly installed at one end of the top of the movable plate 23. The support block 31 is slidably installed inside the movable groove 13. A limit block 32 is fixedly installed on the upper side of the support block 31. A support shaft 33 is fixedly installed on the side of the limit block 32. A support roller 34 is movably sleeved on the outer surface of the support shaft 33.

[0025] The buffer device 5 includes a support frame 51, which is fixedly installed at one end of the top of the operating table 11. A lifting groove 52 is provided on the side of the support frame 51. Limiting rods 53 are movably sleeved at both ends inside the support frame 51. A connecting frame 55 is fixedly installed at the bottom of the limiting rods 53. A pressing spring 54 is movably sleeved on the outer surface of the limiting rods 53. A pressing roller shaft 56 is rotatably installed at the bottom of the connecting frame 55. A positioning block 57 is fixedly installed on the side of the connecting frame 55. The positioning block 57 is slidably installed inside the lifting groove 52. The pressing spring 54 is movably installed between the support frame 51 and the connecting frame 55. The lifting groove 52 is set to limit the positioning block 57, preventing the pressing roller shaft 56 from shifting under force, making the pressing more stable. At the same time, through the action of the pressing spring 54, the plastic film is buffered during the heat sealing process, avoiding the plastic film being too loose during heat sealing, resulting in more pores in the heat-sealed area, which affects the heat sealing effect, or the plastic film being pulled too tight, which makes the plastic film easy to break during the heat sealing process.

[0026] The working process of this utility model is as follows:

[0027] During use, rotating the rotating wheel 22 causes the anti-rotating screw 21 to rotate. The rotation of the anti-rotating screw 21 causes the moving plate 23 to move in opposite directions or in the opposite direction inside the sliding groove 12, thereby driving the limiting plate 24 to move. This facilitates the installation of the unwinding roller shaft 25 and can accommodate unwinding roller shafts 25 of different lengths.

[0028] In use, the plastic film is on the unwinding roller 25, passes over the top of the support roller 34 and the bottom of the pressing roller 56, and then wound onto the take-up roller. The pressing spring 54 presses the plastic film to unfold it. After being wound up in the conventional manner, the heat sealing machine 4 is started and lowered to heat seal the plastic film. During the heat sealing process, the pressing roller 56 assists in unfolding the plastic film, while the support roller 34 assists in moving the plastic film and cushions it. At the same time, the support roller 34 supports the plastic film.
