Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, and in particular to a rust-proof film bag sealing machine. Background Technology

[0002] Sealing machines are widely used equipment in the packaging industry, playing a crucial role, especially in sealing packaging containers such as plastic film bags. By heat-pressing or sealing the bag opening, the airtightness of the product inside the packaging can be ensured, preventing contamination or leakage. Among the many sealing machines, heat sealing is a common and efficient method. Its core component is usually an electric heating strip, which melts the bag opening at high temperature and presses it together. The performance and condition of the heating strip directly determine the sealing quality and production efficiency.

[0003] During continuous production, the heating strip needs to be maintained at a high temperature for extended periods. This presents two problems: First, the molten plastic film easily leaves residue on the heating strip surface, which, if not cleaned promptly, will affect the aesthetics and sealing strength of the subsequent sealing. Second, during work breaks or after completion, the high-temperature heating strip cools down slowly, not only prolonging equipment downtime but also posing a safety hazard of burns to operators. Furthermore, as a component operating under high temperature and physical pressure for extended periods, the heating strip is inherently a consumable part, requiring regular inspection and replacement. However, in some existing sealing machine structures, the installation and wiring of the heating strip are often complex, requiring significant downtime for disassembly and replacement, and potentially necessitating professional operation. This directly leads to increased equipment maintenance costs and reduced production efficiency.

[0004] In summary, existing sealing machines generally suffer from inconvenient and inefficient in-use management (cleaning and cooling) and lifecycle management (maintenance and replacement) of core heating components, which together restrict the overall working efficiency, reliability and ease of use of the equipment.

[0005] Therefore, this utility model proposes a rust-proof film bag sealing machine to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of inconvenient cleaning and cooling of heating components and complex maintenance and replacement structure of existing rust-proof film bag sealing machines, this utility model aims to provide a rust-proof film bag sealing machine with an improved structure that can effectively solve the above problems.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: This utility model provides a rust-proof film bag sealing machine, including a desktop, the surface of which has an installation groove and a groove parallel to the installation groove; a detachable component is installed on the desktop, and a cleaning and cooling component is slidably disposed on the desktop.

[0008] The detachable component includes a heating strip installed in the mounting groove, with ear plates fixedly connected to both ends of the heating strip; a screw hole is provided on the desktop corresponding to the position of the ear plate; the detachable component also includes a screw rod, which detachably passes through the ear plate and is threadedly connected to the screw hole, thereby fixing the heating strip to the desktop.

[0009] The cleaning and cooling assembly includes an L-shaped bracket, with a T-shaped block fixedly connected to the bottom of the L-shaped bracket. The T-shaped block slides within the groove, allowing the entire cleaning and cooling assembly to move along the path of the groove. A nozzle and a handle are also fixedly connected to the L-shaped bracket, with the nozzle facing the heating strip for air blowing cleaning and cooling.

[0010] Preferably, for ease of manual operation, a knob is fixedly connected to one end of the screw. To achieve reliable clamping and fixing, a pressure ring is also fixedly connected to the shank of the screw. When the screw is tightened, the pressure ring abuts against the upper surface of the ear plate when the screw is tightened with the screw hole.

[0011] Preferably, in order to safely and conveniently disconnect the power supply when disassembling the heating strip, the heating strip is electrically connected through a pluggable first connecting wire and a second connecting wire.

This layout is ergonomic and makes it convenient for users to hold the handle and perform push and pull operations.

[0013] Preferably, in order to control the sealing process, the rust-proof film bag sealing machine further includes a machine body and an adjuster. The machine body is mounted on the tabletop, the adjuster is disposed on the machine body, and the adjuster is electrically connected to the heating strip for setting heating parameters.

[0014] Preferably, in order to achieve the pressing and sealing of the film bag, the rust-proof film bag sealing machine further includes a lifting arm and a pressure plate. One end of the lifting arm is rotatably connected to the table, and the pressure plate is fixedly connected to the lower surface of the lifting arm and located above the heating strip to form a pressing structure that cooperates with the heating strip.

[0015] Preferably, to form a complete machine frame and provide operational input, the rust-proof film bag sealing machine also includes support legs and a pedal. The support legs are fixedly connected to both sides of the tabletop, providing stable support for the equipment.

[0023] Please refer to Figures 1 to 5 This utility model provides a rust-proof film bag sealing machine, which aims to solve the problems of inconvenient cleaning and cooling of heating components and complex maintenance and replacement structure in the prior art.

[0024] like Figures 1 to 5 As shown, the rust-proof film bag sealing machine includes a tabletop 1, support legs 2 fixedly connected to both sides of the tabletop 1, and a body 3 mounted on the tabletop 1; the surface of the tabletop 1 has an installation groove 908 and a recess 1005 parallel to the installation groove 908; an adjuster 4 is provided on the body 3; the rust-proof film bag sealing machine also includes a detachable component 9 and a cleaning and cooling component 10 mounted on the tabletop 1; the detachable component 9 includes a heating strip 901 installed in the installation groove 908, and ear plates 902 are fixedly connected to both ends of the heating strip 901; the tabletop 1 A screw hole 909 is provided at the position corresponding to the ear plate 902; the detachable component 9 also includes a screw 903, which detachably passes through the ear plate 902 and is threadedly connected to the screw hole 909; the cleaning and cooling component 10 includes an L-shaped bracket 1001, a T-shaped block 1002 is fixedly connected to the bottom of the L-shaped bracket 1001, the T-shaped block 1002 is slidably fitted in the groove 1005, and a nozzle 1003 and a handle 1004 are fixedly connected to the L-shaped bracket 1001, with the nozzle 1003 facing the heating strip 901; specifically, refer to Figures 2 to 4A knob 904 is fixedly connected to one end of the screw 903, and a pressure ring 905 is fixedly connected to the shaft of the screw 903. When the knob 904 is tightened, the pressure ring 905 abuts against the upper surface of the ear plate 902 while the screw 903 is tightened into the screw hole 909, thereby reliably fixing the heating strip 901. The heating strip 901 is electrically connected via a pluggable and detachable first connecting wire 906 and a second connecting wire 907. The regulator 4 is electrically connected to the heating strip 901 to control its heating parameters. Specifically, refer to... Figure 5 The nozzle 1003 is fixedly connected to the top of the L-shaped bracket 1001, and the handle 1004 is fixedly connected to one side of the L-shaped bracket 1001. The user can hold the handle 1004 to drive the entire cleaning and cooling assembly 10 to slide left and right along the path of the groove 1005.

[0025] To achieve edge sealing and pressing of the rust-proof film bag, the rust-proof film bag sealing machine also includes a pressing mechanism consisting of a boom 5, a pressure plate 8, a connecting column 6, and a pedal 7. The pressing mechanism forms a specific structural fit and connection relationship with the table 1 and the legs 2 fixedly connected to both sides of the table 1.

[0026] Please refer to the following carefully. Figure 1 The structure of this pressing mechanism will be described in detail below: One end of the boom 5 is rotatably connected to the tabletop 1, while the pressure plate 8 is fixedly connected to the lower surface of the boom 5 and located above the heating strip 901. The pedal 7 is rotatably connected between the two support legs 2. One end of the connecting column 6 is rotatably connected to the pedal 7, and the other end of the connecting column 6 is rotatably connected to the boom 5. This structure forms a lever transmission system. When the pedal 7 is pressed down, the pedal 7 drives the connecting column 6 to pull downward, thereby driving the boom 5 to rotate downward around its rotation point, causing the pressure plate 8 to press down and cooperate with the heating strip 901 installed on the tabletop 1 to clamp the anti-rust film bag located between the two. In the non-working state, the connecting column 6 supports the boom 5 to prevent it from falling on its own.

[0027] Based on the above embodiments, the present invention may further include the following preferred technical solutions: In a preferred embodiment, to facilitate the quick fixing and disassembly of the heating strip 901, a knob 904 is fixedly connected to one end of the screw 903 for manual tightening or loosening; a pressure ring 905 is fixedly connected to the rod of the screw 903. When the knob 904 is tightened, the pressure ring 905 abuts against the upper surface of the ear plate 902, thereby achieving reliable clamping and fixing; to achieve safe power disconnection during replacement, the power supply connection of the heating strip 901 is achieved through a pluggable and detachable first connecting wire 906 and second connecting wire 907.

[0028] As another preferred embodiment, in order to achieve ergonomic operation and precise cleaning and cooling of the heating strip 901, the nozzle 1003 in the cleaning and cooling assembly 10 is fixedly connected to the top of the L-shaped bracket 1001, and the handle 1004 is fixedly connected to one side of the L-shaped bracket 1001.

[0029] In another preferred embodiment, in order to achieve parameterized control of the sealing process, the machine body 3 is mounted on the desktop 1, the regulator 4 is set on the machine body 3, and the regulator 4 is electrically connected to the heating strip 901.

[0030] In another preferred embodiment, to form a complete pressing transmission mechanism, one end of the boom 5 is rotatably connected to the tabletop 1, the pressure plate 8 is fixedly connected to the lower surface of the boom 5 and located above the heating strip 901; the support legs 2 are fixedly connected to both sides of the tabletop 1, and the pedal 7 is rotatably connected between the support legs 2; the two ends of the connecting column 6 are rotatably connected to the pedal 7 and the boom 5 respectively, so as to transmit the stepping force.

[0031] Working principle: When performing edge sealing, first place the anti-rust film bag on the heating strip 901. After setting the parameters through the adjuster 4 on the machine body 3, the operator steps on the pedal 7. The pedal 7 pulls the boom 5 down through the connecting column 6, causing the boom 5 to rotate downward around its rotation connection point with the table 1. The pressure plate 8 fixed below the boom 5 presses down accordingly and cooperates with the heating strip 901 to clamp the anti-rust film bag, completing the heating edge sealing work.

[0032] After the edge sealing work is completed, cleaning and cooling operations are carried out. The external air source is connected to the nozzle 1003 of the cleaning and cooling assembly 10. The operator holds the handle 1004 and pushes the L-shaped bracket 1001. Since the T-shaped block 1002 at the bottom of the L-shaped bracket 1001 slides and fits in the groove 1005 of the tabletop 1, the entire cleaning and cooling assembly 10 can move back and forth smoothly along the length of the heating strip 901. During this process, the airflow sprayed from the nozzle 1003 blows away any impurities or residues that may adhere to the surface of the heating strip 901 and cools it down quickly at the same time.

[0033] When the heating strip 901 needs to be replaced or repaired, the operator first loosens the knobs 904 at both ends of the heating strip 901, so that the screw 903 is removed from the screw hole 909, thereby causing the pressure ring 905 fixed on the screw 903 to no longer press against the ear plate 902; then, the first connecting wire 906 and the second connecting wire 907 are disconnected to cut off the power; finally, the entire heating strip 901 can be slid out of the mounting slot 908 on the desktop 1 to complete the disassembly; through the synergistic effect of the detachable component 9 and the cleaning and cooling component 10, this utility model solves the problems of inconvenient cleaning and cooling of heating components and complex repair and replacement structures in the prior art.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
