Description

Technical Field

[0001] This invention relates to the field of plastic film processing and leveling technology, specifically to a plastic film processing and leveling machine and leveling process that can replace the paint layer on a floor. Background Technology

[0002] Plastic film is a thin film made of polyvinyl chloride, polyethylene, and other resins. It can be used for packaging and as a protective coating for other structures. When using plastic film as a flooring film instead of floor paint, multiple plastic films need to be pressed together to form a composite plastic film with anti-slip, waterproof, and deformation-resistant functions. During the processing of the plastic composite film, a plastic film laminating and gluing device is needed to apply adhesive to the films to be laminated. Existing plastic film laminating and gluing devices guide and transport the plastic film using a guide module. During transport, a coating roller picks up adhesive from the adhesive tank and applies it to the plastic film. However, during the gluing process, due to the moisture and stickiness of the adhesive, the plastic film may wrinkle after gluing due to its increased weight, and the wrinkles may even stick together, potentially affecting subsequent gluing and the overall gluing effect. Chinese patent number CN109968789B discloses "A composite device for matte PE film and milky white PE film". In this patent, the composite device for matte PE film and milky white PE film has an appropriate amount of glue between the two film layers during the composite process. At the same time, the film is stably stretched during the composite process. Therefore, the composite film after molding has a stable connection and a smooth product surface, and its stability is relatively high.

[0003] Existing plastic film processing and leveling machines and processes that replace floor paint layers have structural design flaws. Due to the presence of moisture and stickiness in the adhesive, the plastic film wrinkles after being glued because of its increased weight. Furthermore, air bubbles are easily trapped between the plastic films during pressing, causing unevenness in the plastic floor film. Summary of the Invention

[0004] This invention provides a plastic film processing and leveling machine and leveling process to replace the paint layer on the floor, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a plastic film processing and leveling machine to replace the paint layer on a floor, comprising a support frame, a housing fixedly connected to the top of the support frame, a support plate fixedly connected to the surface of the housing, a plastic film roller rotatably connected to the upper position of the support plate, a film roller rotatably connected to the top of the housing, and a take-up roller rotatably connected to the bottom of the housing; further comprising:

[0006] A blocking component is fixedly installed on the upper part of the inner side of the housing. An atomizing component is fixedly connected to the inner side of the blocking component. A side shell is fixedly connected to the surface of the blocking component. A contact component is fixedly connected to the surface of the side shell. An electric wire is fixedly connected to the surface of the contact component. A cylinder is fixedly connected to the bottom of the blocking component. A support cover is fixedly connected to the surface of the cylinder. A lead screw slide is fixedly connected to the surface of the support cover. A pressure roller is rotatably connected to the output end of the lead screw slide.

[0007] A sliding rod, with both ends fixedly installed on the inner side of the housing, has a sliding assembly slidably connected to its surface, and a heating assembly fixedly connected to its surface. There are two heating assemblies. The sliding assembly is used to drive the two heating assemblies closer to each other to press the plastic film together. The heating assembly is used to heat and bond the plastic film and adhesive film after pressing.

[0008] Preferably, the surface of the adhesive film roller is wound with a hot melt adhesive film, and there are two plastic film rollers, which are symmetrically distributed on both sides of the barrier component with the hot melt adhesive film as the center. The hot melt adhesive film is unwound downwards, and the plastic films arranged opposite each other are symmetrically distributed with the hot melt adhesive film as the center. The side shells protect the plastic films, and the pressure rollers arranged opposite each other are brought closer together under the drive of the screw slide. The pressure rollers apply pressure to the plastic film and the hot melt adhesive film to press them together.

[0009] Preferably, there are two pressure rollers, and the two pressure rollers are symmetrically distributed around the hot melt adhesive film. The pressure rollers are used for pressing the plastic film and the adhesive film. The output end of the lead screw slide is rotatably connected to the end face of the pressure roller.

[0010] Preferably, the barrier component includes a housing, the surface of which is fixedly mounted on the upper part of the inner side of the housing, an opening is provided at the bottom of the housing, a bending plate is fixedly connected to the inner side of the housing, and a water guide pipe is fixedly connected to the housing near the bending plate.

[0011] Preferably, the atomizing component includes an extension rod, one end of which is fixedly installed on the inner side of the housing, and the other end of which is fixedly connected to a water storage tank. An atomizing nozzle is fixedly connected to the surface of the water storage tank. Hot melt adhesive film is easy to adhere to the surface of other components, while the surface of plastic film is prone to static electricity, which can cause wrinkles and unevenness between plastic films during pressing. In this device, the hot melt adhesive film is conveyed vertically downwards, and the hot melt adhesive film is not easily bent under the action of gravity. At the same time, the atomizing nozzle atomizes the water inside the water storage tank and sprays it onto the surface of the hot melt adhesive film. The water forms a lubricating layer on the surface of the hot melt adhesive film, making it less likely for the hot melt adhesive film to adhere to the surface of other components.

[0012] Preferably, the contact assembly includes a connecting plate, the surface of which is fixedly mounted on the side of the side shell surface, and a conductive shell is fixedly connected to the side of the connecting plate away from the side shell.

[0013] Preferably, the contact assembly further includes a bearing, which is fixedly mounted on the inner side of the conductive housing. A contact shaft is fixedly connected to the inner side of the bearing, and the surface of the contact shaft is in close contact with the surface of the plastic film.

[0014] Preferably, a suction pipe is fixedly connected to the bottom of the inner side of the housing, a motor is fixedly connected to the surface of the suction pipe, a threaded rod is fixedly connected to the output end of the motor, the surface of the threaded rod is connected to the inner side of the displacement assembly through threads, a slide rod is fixedly connected to the inner side of the housing, an anti-deviation roller is fixedly connected to the lower position of the surface of the suction pipe, the hot melt adhesive film moves vertically downward, the atomizing assembly sprays atomized water evenly onto the surface of the hot melt adhesive film, and under the drive of the pressure roller, the plastic film and the hot melt adhesive film are pressed together, the hot melt adhesive film and the plastic film are cold-pressed together at the position of the pressure roller, and under the drive of the take-up roller, the pressed plastic film and the hot melt adhesive film move to the position between the heating assembly, and the take-up roller stops rotating.

[0015] Preferably, the displacement assembly includes a displacement plate, the inner side of the displacement plate is slidably connected to the surface of the slide rod, an arc-shaped cylinder is fixedly connected to the surface of the displacement plate, an arc-shaped plunger rod is slidably connected to the inner side of the arc-shaped cylinder, and a liquid passage pipe is fixedly connected to the surface of the arc-shaped cylinder.

[0016] Preferably, the heating assembly includes a heating shell, the inner side of which is fixedly mounted on the end face of the arc-shaped plunger rod. The heating shell has a cavity inside. A motor drives the threaded rod to rotate, and two opposing plates slide closer to each other on the surface of the slide rod. The heating shell surface is preferentially pressed together near the center of the plastic film. A control valve delivers heating oil to the interior of the heating shell, causing the heating shells to press against each other. A liquid pipe delivers hydraulic pressure to the interior of the arc-shaped cylinder, which pushes the arc-shaped plunger rod to rotate. The rotation axis of the arc-shaped plunger rod is collinear with the axis of the arc-shaped cylinder, thereby causing the pressed heating shells to separate and rotate.

[0017] Preferably, the heating assembly further includes a control valve, the surface of which is fixedly mounted on the surface of the heating shell. There are two heating shells, and a spring is fixedly connected between the two heating shells. An arc-shaped plate is fixedly connected to the surface of the heating shell. The atomizing nozzle atomizes the liquid inside the water tank and sprays it evenly onto the surface of the hot melt adhesive film, so that both sides of the hot melt adhesive film have a water layer. The constriction of the shell makes it easy for the dispersed water particles to be captured and condensed into water droplets. The bending plate intercepts the condensed water droplets, and the water guide pipe promptly discharges the condensed water, thereby avoiding the problem of the condensed liquid seeping in after the plastic film and the hot melt adhesive film are bonded, causing the composite film to cool down rapidly and become uneven. A water film is formed between the plastic film and the hot melt adhesive film. The water film makes it difficult for gas to remain between the plastic films. The heating shells are close to each other and squeeze the middle of the plastic film.

[0018] A leveling process for a plastic film processing leveling machine that replaces the paint layer on a floor includes the following steps:

[0019] Step 1: Conveying and guiding. The hot melt adhesive film is conveyed vertically downwards. The hot melt adhesive film is not easily bent under the action of gravity. The surfaces of the two plastic film rollers are both wound with plastic film, and the surfaces of the adhesive film rollers are wound with hot melt adhesive film. The hot melt adhesive film is unwound downwards. The plastic films set opposite each other are symmetrically distributed with the hot melt adhesive film as the center. The side shells protect the plastic film. The winding rollers wind up the tightly pressed plastic film.

[0020] Step 2: Water spraying for lubrication. The atomizing nozzle atomizes the liquid inside the water tank and sprays it evenly onto the surface of the hot melt adhesive film, so that there is a water layer on both sides of the hot melt adhesive film. The constriction of the shell makes it easy for the dispersed water particles to be captured and condensed into water droplets. The bending plate intercepts the condensed water droplets that flow down, and the water guide pipe promptly discharges the condensed water to prevent the condensed liquid from seeping in after the plastic film and the hot melt adhesive film are bonded, which would cause the composite film to cool down rapidly and become uneven.

[0021] Step 3: Opposite pressing. The hot melt adhesive film moves vertically downward. The atomizing component sprays atomized water evenly onto the surface of the hot melt adhesive film. Driven by the pressure roller, the plastic film and the hot melt adhesive film are pressed together. The hot melt adhesive film and the plastic film are cold-pressed together at the position of the pressure roller. Driven by the winding roller, the pressed plastic film and the hot melt adhesive film move to the position between the heating components.

[0022] Step 4: Adhesive winding. The rotation axis of the arc-shaped plunger rod is collinear with the axis of the arc-shaped cylinder, causing the heated shell to rotate separately. The surface of the heated shell is provided with an arc surface, which is in close contact with the surface of the plastic film. This pushes the plastic film and the hot melt adhesive film from the center outward, making the plastic film and the hot melt adhesive film tightly pressed together. Under the heating action of the heating oil, the hot melt adhesive film melts and adheres tightly to the surface of the plastic film. The winding roller winds up the tightly pressed plastic film.

[0023] This invention provides a plastic film processing and leveling machine and a leveling process to replace the paint layer on floors. It has the following beneficial effects:

[0024] 1. The plastic film processing and leveling machine and process that replaces the floor paint layer involves guiding the pressed plastic film and hot melt adhesive film to a position between two opposing components. The two heating components are driven by the opposing components to press the plastic film tightly against the plastic film. The plastic film and hot melt adhesive film are squeezed close together, and under the heating action of the heating components, the hot melt adhesive film melts and tightly glues the two plastic films together. The winding roller winds up the tightly glued plastic film, which solves the problem of plastic film wrinkling due to the increased weight of the plastic film after gluing because the glue has a certain amount of moisture and stickiness.

[0025] 2. This plastic film processing and leveling machine and process replaces the floor paint layer. The extension rod supports and limits the water storage tank, and the side shell protects the movement of the plastic film. Under the guidance of the pressure roller, the plastic film is bonded to the hot melt adhesive film. The surface of the contact shaft is tightly pressed against the surface of the plastic film. The inner surfaces of the contact shaft and the conductive shell are made of metal conductive material. The contact shaft guides the static electricity generated on the surface of the plastic film due to friction to the inner surface of the conductive shell. Then, the wire guides the charge to the ground, thereby avoiding the adhesion of impurities to the surface of the plastic film due to static electricity, making the plastic film and adhesive film more flat when pressed together.

[0026] 3. This plastic film processing and leveling machine and process, which replaces the floor paint layer, uses a plastic composite film to replace the floor paint layer, thus eliminating the need for a moisture-proof paint layer on the floor. The motor drives the threaded rod to rotate, and the threaded rod uses the lifting characteristics of the thread to cause the opposing components to move relative to each other. The heating components move closer to each other under the action of the opposing components. The middle position of the heating components first squeezes the plastic film, and then the side positions of the heating components gradually squeeze the plastic film under the action of the opposing components. This squeezes out the lubricating water and a small number of air bubbles between the plastic film and the hot melt adhesive film, effectively preventing air bubbles from causing wrinkles in the plastic film. This solves the problem of uneven plastic flooring caused by air bubbles easily getting trapped when the plastic films are pressed together.

[0027] 4. The plastic film processing and leveling machine and process that replaces the floor paint layer features a curved surface on the heating shell. This curved surface is in close contact with the surface of the plastic film, pushing the plastic film and hot melt adhesive film from the center outwards. This results in a tight bond between the plastic film and the hot melt adhesive film. Under the heating action of the heating oil, the hot melt adhesive film melts and bonds tightly to the surface of the plastic film. The hot melt adhesive film replaces the application of glue. Driven by the curved plunger rod, the curved surface of the heating shell squeezes the plastic film from the center outwards, thereby squeezing out the liquid and gas between the plastic films, resulting in a smoother composite plastic film.

[0028] 5. The plastic film processing and leveling machine and process that replaces the floor paint layer, driven by the arc-shaped plunger rod, melts the hot melt adhesive film while the water between the plastic film and the hot melt adhesive film forms a water film, which lubricates the position between the hot melt adhesive film and the plastic film, thereby effectively preventing gas from being trapped between the films. The lubricating water vaporizes when heated. After the bonding is completed, the surface of the arc plate is in close contact with the surface of the suction pipe. The suction pipe discharges the vaporized water vapor, thereby avoiding excess moisture from interfering with the bonding of the plastic film and the hot melt adhesive film.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] First embodiment: as follows Figures 2-4 , Figure 7 As shown, the present invention provides a technical solution: a plastic film processing and leveling machine and leveling process to replace the paint layer of the floor, including a support frame 1, a housing 2 fixedly connected to the top of the support frame 1, and a support plate 3 fixedly connected to the surface of the housing 2; it also includes a plastic film roller 4, an adhesive film roller 5 and a winding roller 6;

[0041] Plastic film processing and leveling machines that replace floor paint layers also include:

[0042] The blocking component 7 is fixedly installed on the upper part of the inner side of the housing 2. The atomizing component 9 is fixedly connected to the inner side of the blocking component 7. The side shell 10 is fixedly connected to the surface of the blocking component 7. The contact component 11 is fixedly connected to the surface of the side shell 10. The wire 12 is fixedly connected to the surface of the contact component 11. The bottom of the blocking component 7 is fixedly connected to the cylinder 13. The surface of the cylinder 13 is fixedly connected to the support cover 14. The surface of the support cover 14 is fixedly connected to the lead screw slide 15. The output end of the lead screw slide 15 is rotatably connected to the pressure roller 16.

[0043] A plastic film roller 4 is rotatably connected to the upper part of the surface of the support plate 3, a glue film roller 5 is rotatably connected to the top of the machine housing 2, and a take-up roller 6 is rotatably connected to the bottom of the machine housing 2.

[0044] The slide rod 19 has two ends fixedly installed on the inner side of the housing 2. The surface of the slide rod 19 is slidably connected to the displacement assembly 20. The surface of the displacement assembly 20 is fixedly connected to the heating assembly 21. There are two heating assemblies 21. The displacement assembly 20 is used to drive the two heating assemblies 21 to move closer to each other to press the plastic film. The heating assembly 21 is used to heat and bond the plastic film and the adhesive film after pressing.

[0045] There are two pressure rollers 16, and the two pressure rollers 16 are symmetrically distributed around the hot melt adhesive film. The pressure rollers 16 are used for pressing plastic film and adhesive film. The output end of the screw slide table 15 is rotatably connected to the end face of the pressure rollers 16.

[0046] In use, there are two plastic film rollers 4, both of which are wound with plastic film. The surface of the adhesive film roller 5 is wound with hot melt adhesive film. The hot melt adhesive film is unwound downwards. The plastic films are symmetrically distributed with the hot melt adhesive film as the center. The side shell 10 protects the plastic film. The opposing pressure rollers 16 are driven by the screw slide 15 to approach each other. The pressure rollers 16 apply pressure to the plastic film and the hot melt adhesive film to press them together. The pressed plastic film and the hot melt adhesive film are guided to the position between the two opposing components 20. The two heating components 21 are driven by the opposing components 20 to press the plastic film tightly. The plastic film and the hot melt adhesive film are squeezed close together. Under the heating action of the heating components 21, the hot melt adhesive film melts and presses the two plastic films tightly together. The take-up roller 6 takes up the tightly pressed plastic film. This solves the problem that the plastic film wrinkles after being glued due to the increased weight of the plastic film because of the moisture and stickiness of the glue.

[0047] Second embodiment: as follows Figures 3-6 As shown, the barrier component 7 includes a housing 71, the surface of which is fixedly mounted on the upper part of the inner side of the housing 2. The bottom of the housing 71 has an opening. A bending plate 72 is fixedly connected to the inner side of the housing 71. A water guide pipe 73 is fixedly connected to the housing 71 near the bending plate 72. The atomizing component 9 includes an extension rod 91, one end of which is fixedly mounted on the inner side of the housing 71. The other end of which is fixedly connected to a water tank 92. An atomizing nozzle 93 is fixedly connected to the surface of the water tank 92. The contact component 11 includes a connecting plate 111, the surface of which is fixedly mounted on the side of the side shell 10. A conductive shell 112 is fixedly connected to the side of the connecting plate 111 away from the side shell 10. The contact component 11 also includes a bearing 113, which is fixedly mounted on the inner side of the conductive shell 112. A contact shaft 114 is fixedly connected to the inner side of the bearing 113. The surface of the contact shaft 114 is in close contact with the surface of the plastic film.

[0048] During use, hot melt adhesive film easily adheres to the surface of other components, while the surface of plastic film is prone to static electricity, which can cause wrinkles and unevenness between plastic films during pressing. In this device, the hot melt adhesive film is conveyed vertically downwards, and it is not easy to bend under the action of gravity. At the same time, the atomizing nozzle 93 atomizes the water inside the water tank 92 and sprays it onto the surface of the hot melt adhesive film. The water forms a lubricating layer on the surface of the hot melt adhesive film, making it difficult for the hot melt adhesive film to adhere to the surface of other components. The extension rod 91 supports and limits the water tank 92, and the side shell 10 protects the movement of the plastic film. The plastic film is combined with the hot melt adhesive film under the guidance of the pressure roller 16. The surface of the contact shaft 114 is in close contact with the surface of the plastic film. The inner surfaces of the contact shaft 114 and the conductive shell 112 are made of metal conductive material. The contact shaft 114 guides the static electricity generated by friction on the surface of the plastic film to the inner surface of the conductive shell 112. Then the wire 12 guides the charge to the ground, thereby preventing impurities from adhering to the surface of the plastic film due to static electricity, making the plastic film and adhesive film more flat when pressed together.

[0049] Third embodiment: as follows Figure 7 As shown, the shifting assembly 20 is positioned below the pressure roller 16. A heating assembly 21 is fixedly connected to the surface of the shifting assembly 20. There are two heating assemblies 21. The shifting assembly 20 is used to drive the two heating assemblies 21 to move closer to each other to press the plastic film. The heating assemblies 21 are used to heat and bond the plastic film and adhesive film after pressing. A suction pipe 8 is fixedly connected to the bottom of the inner side of the machine housing 2. A motor 18 is fixedly connected to the surface of the suction pipe 8. A threaded rod is fixedly connected to the output end of the motor 18. The surface of the threaded rod is connected to the inner side of the shifting assembly 20 through threads. A slide rod 19 is fixedly connected to the inner side of the machine housing 2. An anti-deviation roller 17 is fixedly connected to the lower position of the surface of the suction pipe 8.

[0050] In use, a plastic composite film replaces the floor paint layer, eliminating the need for a moisture-proof paint layer on the floor. The hot melt adhesive film moves vertically downwards, and the atomizing component 9 evenly sprays atomized water onto the surface of the hot melt adhesive film. Driven by the pressure roller 16, the plastic film and the hot melt adhesive film are pressed together. The hot melt adhesive film and the plastic film are cold-pressed together at the position of the pressure roller 16. Driven by the winding roller 6, the pressed plastic film and the hot melt adhesive film move to the position between the heating components 21. The winding roller 6 stops rotating, and the motor 18 drives the threaded rod to rotate. The threaded rod causes the opposing components 20 to move relative to each other through the threaded lifting characteristics. The heating components 21 move closer to each other under the action of the opposing components 20. The middle position of the heating components 21 squeezes the plastic film first, and then the side position of the heating components 21 gradually squeezes the plastic film under the action of the opposing components 20. This squeezes out the lubricating water and a small number of air bubbles between the plastic film and the hot melt adhesive film, effectively preventing air bubbles from causing wrinkles in the plastic film and solving the problem of uneven plastic flooring caused by air bubbles easily getting trapped when pressing the plastic films together.

[0051] Fourth embodiment: as Figures 7-9 As shown, the displacement assembly 20 includes a displacement plate 201, the inner side of which is slidably connected to the surface of the slide rod 19. An arc-shaped cylinder 202 is fixedly connected to the surface of the displacement plate 201. An arc-shaped plunger rod 204 is slidably connected to the inner side of the arc-shaped cylinder 202. A liquid passage pipe 203 is fixedly connected to the surface of the arc-shaped cylinder 202. The heating assembly 21 includes a heating shell 211, the inner side of which is fixedly installed at the end face of the arc-shaped plunger rod 204. A cavity is provided inside the heating shell 211. The heating assembly 21 also includes a control valve 212, the surface of which is fixedly installed on the surface of the heating shell 211. There are two heating shells 211, and a spring 213 is fixedly connected between the two heating shells 211. An arc-shaped plate 214 is fixedly connected to the surface of the heating shell 211.

[0052] In operation, motor 18 drives the threaded rod to rotate, and two opposing plates 201 slide closer to each other on the surface of slide rod 19. The heating shell 211 is preferentially pressed together near the center of the plastic film. Control valve 212 delivers heating oil to the interior of heating shell 211, causing the heating shells 211 to press against each other. Liquid pipe 203 delivers hydraulic pressure to the interior of arc cylinder 202, which pushes arc plunger rod 204 to rotate. The rotation axis of arc plunger rod 204 is collinear with the axis of arc cylinder 202, thereby causing the pressed heating shells 211 to separate and rotate. The heating shell 211 has an arc surface that is in close contact with the surface of the plastic film. This pushes the plastic film and the hot melt adhesive film from the center outward, making them tightly bonded. Under the heating action of the heating oil, the hot melt adhesive film melts and bonds tightly to the surface of the plastic film. The hot melt adhesive film replaces the application of glue. Driven by the arc-shaped plunger rod 204, the arc surface of the heating shell 211 squeezes the plastic film from the center outward, thereby squeezing out the liquid and gas between the plastic films, making the composite plastic film form more flat.

[0053] Fifth embodiment: as follows Figure 5 , Figure 9As shown, the surface of the housing 71 is fixedly installed on the upper position of the inner side of the housing 2. The bottom of the housing 71 is provided with an opening. The inner side of the housing 71 is fixedly connected with a bending plate 72. The housing 71 is fixedly connected with a water guide pipe 73 near the bending plate 72. The atomizing assembly 9 includes an extension rod 91. One end of the extension rod 91 is fixedly installed on the inner side of the housing 71. The other end of the extension rod 91 is fixedly connected to a water tank 92. The surface of the water tank 92 is fixedly connected with an atomizing nozzle 93. The inner side of the heating shell 211 is fixedly installed on the end face of the arc-shaped plunger rod 204. The heating shell 211 has a cavity inside. The heating assembly 21 also includes a control valve 212. The surface of the control valve 212 is fixedly installed on the surface of the heating shell 211. There are two heating shells 211. A spring 213 is fixedly connected between the two heating shells 211. An arc-shaped plate 214 is fixedly connected to the surface of the heating shell 211.

[0054] During use, the atomizing nozzle 93 atomizes the liquid inside the water tank 92 and sprays it evenly onto the surface of the hot melt adhesive film, ensuring a water layer on both sides of the film. The constriction of the shell 71 allows dispersed water particles to be easily captured and condensed into water droplets. The bending plate 72 intercepts the condensed water droplets, and the water guide pipe 73 promptly drains the condensed water, thus preventing the problem of condensed liquid seeping into the composite film after the plastic film and hot melt adhesive film are bonded, causing rapid cooling and unevenness. A water film forms between the plastic film and the hot melt adhesive film, preventing gas from easily accumulating in the plastic film. The heating shells 211 are positioned close to each other at the center of the plastic film being extruded. Under the action of the arc-shaped plunger rod 204, the hot melt adhesive film is melted, and water forms between the plastic film and the hot melt adhesive film, which lubricates the position between the hot melt adhesive film and the plastic film, thereby effectively preventing gas from accumulating between the films. The lubricating water vaporizes when heated. After the bonding is completed, the surface of the arc-shaped plate 214 is in close contact with the surface of the suction pipe 8, and the suction pipe 8 discharges the vaporized water vapor, thereby avoiding excess moisture from interfering with the bonding of the plastic film and the hot melt adhesive film.

[0055] Sixth embodiment: as follows Figures 1-9 As shown, a leveling process for a plastic film processing leveling machine that replaces the paint layer on a floor includes the following steps:

[0056] Step 1: Conveying and guiding. The hot melt adhesive film is conveyed vertically downwards. The hot melt adhesive film is not easily bent under the action of gravity. The surfaces of the two plastic film rollers 4 are both wound with plastic film, and the surface of the adhesive film roller 5 is wound with hot melt adhesive film. The hot melt adhesive film is unwound downwards. The plastic films set opposite each other are symmetrically distributed with the hot melt adhesive film as the center. The side shell 10 protects the plastic film. The winding roller 6 winds up the tightly pressed plastic film.

[0057] Step 2: Water spraying for lubrication. The atomizing nozzle 93 atomizes the liquid inside the water tank 92 and sprays it evenly onto the surface of the hot melt adhesive film, so that there is a water layer on both sides of the hot melt adhesive film. The constriction of the shell 71 makes it easy for the dispersed water particles to be captured and condensed into water droplets. The bending plate 72 intercepts the condensed water droplets and the water guide pipe 73 promptly discharges the condensed water to prevent the condensed liquid from seeping in after the plastic film and the hot melt adhesive film are bonded, causing the composite film to cool down rapidly and become uneven.

[0058] Step 3: Opposite pressing. The hot melt adhesive film moves vertically downward. The atomizing component 9 sprays atomized water evenly onto the surface of the hot melt adhesive film. Driven by the pressure roller 16, the plastic film and the hot melt adhesive film are pressed together. The hot melt adhesive film and the plastic film are cold pressed together at the position of the pressure roller 16. Driven by the winding roller 6, the pressed plastic film and the hot melt adhesive film move to the position between the heating components 21.

[0059] Step 4: Adhesive winding. The rotation axis of the arc-shaped plunger rod 204 is collinear with the axis of the arc-shaped cylinder 202, thereby causing the pressed heating shell 211 to separate and rotate. The surface of the heating shell 211 is provided with an arc surface, which is in close contact with the surface of the plastic film, thereby pushing the plastic film and the hot melt adhesive film from the center to the outside, so that the plastic film and the hot melt adhesive film are tightly pressed together. Under the heating action of the heating oil, the hot melt adhesive film melts and is tightly bonded to the surface of the plastic film. The winding roller 6 winds up the tightly pressed plastic film.

[0060] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, the phrase "comprising an element defined as..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

The leveling process of a plastic film processing leveling machine that replaces the paint layer on a floor, as described in claim 7, is characterized in that: Includes the following steps: Step 1: Conveying and guiding. The hot melt adhesive film is conveyed vertically downward. The hot melt adhesive film is not easily bent under the action of gravity. The surfaces of the two plastic film rollers (4) are both wrapped with plastic film, and the surface of the adhesive film roller (5) is wrapped with hot melt adhesive film. The hot melt adhesive film is unwound downward. The plastic films set opposite each other are symmetrically distributed with the hot melt adhesive film as the center. The side shell (10) protects the plastic film. The winding roller (6) winds up the tightly pressed plastic film. Step 2: Water spraying lubrication. The atomizing nozzle (93) atomizes the liquid inside the water tank (92) and sprays it evenly onto the surface of the hot melt adhesive film, so that there is a water layer on both sides of the hot melt adhesive film. The constriction of the shell (71) makes it easy for the dispersed water particles to be captured by the shell (71) and condensed into water droplets. The bending plate (72) intercepts the condensed water droplets flowing down, and the water guide pipe (73) promptly discharges the condensed water to prevent the condensed liquid from seeping in after the plastic film and the hot melt adhesive film are bonded, causing the composite film to cool down rapidly and become uneven. Step 3: Opposite pressing. The hot melt adhesive film moves vertically downward. The atomizing component (9) sprays atomized water evenly onto the surface of the hot melt adhesive film. Driven by the pressure roller (16), the plastic film and the hot melt adhesive film are pressed together. The hot melt adhesive film and the plastic film are cold pressed together at the position of the pressure roller (16). Driven by the winding roller (6), the pressed plastic film and the hot melt adhesive film move to the position between the heating component (21). Step 4: Adhesive winding. The rotation axis of the arc-shaped plunger rod (204) is collinear with the axis of the arc-shaped cylinder (202), thereby causing the pressed heating shell (211) to separate and rotate. The surface of the heating shell (211) is provided with an arc surface, which is in close contact with the surface of the plastic film, thereby pushing the plastic film and the hot melt adhesive film from the center to the outside, so that the plastic film and the hot melt adhesive film are tightly bonded. Under the heating action of the heating oil, the hot melt adhesive film melts and is tightly bonded to the surface of the plastic film. The winding roller (6) winds up the tightly bonded plastic film.
