Description

Technical Field

[0001] This invention relates to the field of equipment for producing waterproof membranes, and in particular to a waterproof membrane packaging machine. Background Technology

[0002] Waterproof membrane is a commonly used type of membrane in existing technologies, including extrusion molding and compression molding. After production, it often needs to be packaged with packaging film before leaving the factory. Existing packaging usually uses automatic packaging machines, which can automatically complete the film-coating and packaging work.

[0003] Specifically, the roll material is rolled up and placed in the laminating position, then the packaging film is cut, and finally heat-shrink wrapping is performed. This packaging method is simple and efficient. However, existing laminating and packaging machines usually have a problem: they use a hot melt blade to cut the packaging film, so the cut area is prone to curling up after cutting. This can lead to uneven packaging during subsequent heat shrinking, affecting the quality of the packaging. To solve this problem, the existing structure needs to be improved.

[0004] In addition, in the existing technology, when the roll material is heat-shrinked and laminated, it is rotated by a rotating roller in order to ensure even heating. This rotation process can easily cause wrinkles in the packaging film during the heat-shrinking process. Moreover, since the roll material is supported by the rotating roller, the contact surface is large, and the area where wrinkles occur is also large. Summary of the Invention

[0005] The purpose of this invention is to provide a waterproof roll packaging machine that solves the problem that existing packaging films are prone to wrinkling during heat shrinking due to rolling and large support area.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A device includes a frame with a film-coating position; a packaging film conveying mechanism disposed on the frame for conveying packaging film to the inlet side of the film-coating position; a feeding mechanism disposed on the frame for conveying waterproof membrane to the film-coating position; a hot-melt cutting mechanism, lifted and positioned on the frame, located between the packaging film conveying mechanism and the film-coating position; a heat-shrink chamber disposed on the frame, located on the outlet side of the film-coating position; four heat-shrink support rollers disposed in the heat-shrink chamber for supporting the waterproof membrane being coated; two sets of lifting mechanisms disposed above and below the heat-shrink support rollers, respectively, moving closer to or away from the heat-shrink support rollers after lifting; upper and lower surface heat-shrink assemblies disposed at the output end of the lifting mechanisms; and a rapid cooling mechanism further disposed in the heat-shrink chamber.

[0007] A ball-bearing support structure is adopted, which minimizes the support area and avoids hindering heat shrinking. Then, through the upper and lower surface heat shrinking components, the material on the heat shrinking support ball can be evenly heat-shrinked, resulting in a heat-shrink packaged material. During the heat shrinking process, the material wrapped in the packaging film is not rolled, so the packaging film is less likely to wrinkle during heat shrinking. After packaging, it fits the material surface better, making it easier to move the material. At the same time, the packaging film is less likely to be damaged due to wrinkles. After heat shrinking, the material surface is quickly cooled, which effectively prevents the entire area or part of the film from continuously shrinking due to continuous heating. Continuous shrinking from all sides can compress the material inside the film, which can easily affect the material inside the film. Continuous shrinking in part of the film can cause wrinkles on the surface of the film. The heat shrinking support ball is connected to the frame at the bottom of the heat shrinking chamber through a support connecting frame.

[0008] As described above, the heat shrink chamber is located on the frame and is a chamber with an open bottom. When the heat shrink components on the upper and lower surfaces move upward, they can be lifted to the plane where the bottom of the heat shrink chamber is located, close to the material on the heat shrink support ball.

[0009] As a further technical solution, the heat shrink chamber is also provided with two end heating plates, which are respectively raised and lowered on both sides of the heat shrink chamber. The end heating plates have a bowl-shaped structure. The upper and lower surface heat shrink components are arc-shaped heating plates, which are set at the output end of the lifting mechanism.

[0010] The end heating plate heats the end, and the upper and lower surface heat shrinking components heat the upper and lower parts. This heating ensures uniform heat shrinking and the speed can be easily controlled by adjusting the temperature.

[0011] As a further technical solution, the lifting mechanism includes a linear drive component disposed at the top and bottom of the heat shrink chamber. The output end of the linear drive component located at the top of the heat shrink chamber passes through the top of the heat shrink chamber and connects to the upper and lower surface heat shrink assembly above the heat shrink support ball. The output end of the linear drive component located at the bottom of the heat shrink chamber connects upward to the upper and lower surface heat shrink assembly below the heat shrink support ball. A guide rail is disposed on the side wall of the heat shrink chamber. The two ends of the upper and lower surface heat shrink assembly are provided with grooves adapted to the guide rail.

[0012] As a further technical solution, the feeding mechanism includes an active roller, which is rotatably mounted on the frame; and a push plate, which is oscillatingly mounted on the frame. After the push plate oscillates, it moves closer to or further away from the film-coating position. A material width capture and detection camera is provided above the feeding mechanism.

[0013] The diameter of the material can be captured and detected during feeding. Since the diameter of each roll of material will have a certain error, only after the diameter of the material is accurately measured can the appropriate length of film be cut.

[0014] As a further technical solution, the packaging film conveying mechanism includes an upper film feeding roller, which is disposed on the frame and located above the film covering position; a lower film feeding roller, which is disposed on the frame and located below the film covering position; and two sets of clamping rollers, which are respectively located next to the upper film feeding roller and the lower film feeding roller.

[0015] As a further technical solution, the hot melt cutting mechanism includes an upper cutter, which is lifted and lowered on the frame via an upper fixed seat, and the upper fixed seat is horizontally slidably connected to the frame; and a cutter seat, which is disposed on the frame. After the upper cutter is lifted and lowered, it approaches or moves away from the cutter seat, and the hot cutting surface of the cutter seat is flush with the upper surface of the coating position.

[0016] The upper and lower cutter positions can be adjusted to work in conjunction with the material width capture and detection camera to accurately determine the film length, which also ensures that the film can be tightly adhered to the material surface after heat shrinking.

[0017] As a further technical solution, the upper cutter is connected to the upper fixed seat through an elastic element; a punch is connected to the upper fixed seat, and the upper cutter has a sliding hole, the punch is slidably disposed in the sliding hole, the cutter seat has a punching opening, and the punch is pressed into the punching opening after it descends.

[0018] As a further technical solution, one end of the film-coating position is hinged to the frame, and the other end is raised and lowered on the frame, with the raised and lowered end away from the hot melt cutting mechanism.

[0019] As a further technical solution, the rapid cooling mechanism includes cooling air outlets evenly distributed in the heat shrink chamber, one end of the heat shrink support ball is provided with a pusher plate, the pusher plate is connected to the pusher cylinder, the other end of the heat shrink support ball is the discharge end, the discharge end is provided with a discharge port, the discharge port is blocked by a flexible heat insulation curtain, and the discharge end is provided with a weighing mechanism.

[0020] Cooling the material before pushing it out reduces the likelihood of wrinkles on the coating surface and allows for weighing after discharge.

[0021] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: 1. A ball-bearing support structure is adopted, which minimizes the support area and avoids hindering heat shrinking. Then, through the upper and lower surface heat shrinking components, the material on the heat shrinking support ball can be evenly heat-shrinked, resulting in a heat-shrink packaged material. During the heat shrinking process, the material wrapped in the packaging film is not rolled, so the packaging film is less likely to wrinkle during heat shrinking. After packaging, it fits the material surface better, making it easier to move the material. At the same time, the packaging film is less likely to be damaged due to wrinkles. After heat shrinking, the material surface is quickly cooled, which effectively prevents the entire area or part of the film from continuously shrinking due to continuous heating. Continuous shrinking from all sides can compress the material inside the film, which can easily affect the material inside the film. Continuous shrinking in part of the film can cause wrinkles on the surface of the film.

[0022] 2. A heat-shrink chamber is installed on the frame to facilitate the heat shrinking of the outer packaging bag of the waterproof membrane. This allows the packaging film to wrap the waterproof membrane. The rolled waterproof membrane is conveyed by the feeding unit to one side of the packaging film at the inlet of the packaging station. The feeding mechanism then continues to move, driving the rolled waterproof membrane to contact and press against the packaging bag, causing the packaging film to wrap around the surface of the waterproof membrane, forming a "U" shape. Then, the heat-cutting mechanism presses and heat-melts the packaging film, resulting in a cylindrical structure wrapped around the waterproof membrane, with its two sides... Both ends extend beyond the two ends of the waterproof membrane. The remaining packaging film is heat-cut and glued together to form a complete packaging film, facilitating the next wrapping. The wrapped waterproof membrane is then transported into the heat-shrink chamber and falls onto the heat-shrink support rollers. The lifting mechanism then moves the upper and lower surface heat-shrink components up and down, bringing them close to the waterproof membrane with the packaging film on the heat-shrink support rollers. This causes the outer packaging film of the waterproof membrane to shrink evenly due to heat, resulting in a complete and smooth outer packaging film, thus completing the packaging of the waterproof membrane.

[0023] 3. The diameter of the material can be captured and detected during feeding. Since the diameter of each roll of material will have a certain error, only after the diameter of the material is accurately measured can the appropriate length of film be cut.

[0024] 4. The upper and lower cutter positions can be adjusted to work in conjunction with the material width capture and detection camera to accurately determine the wrapping length, which also ensures that the wrapping can be tightly adhered to the material surface after heat shrinking.

Specific Implementation Example 1: like Figures 1 to 7 As shown, this embodiment proposes a waterproof roll packaging machine, including a frame 10 with a film-covering position 11; a packaging film conveying mechanism 20, disposed on the frame 10, for conveying packaging film to the feeding end side of the film-covering position 11; a feeding mechanism 30, disposed on the frame 10, for conveying waterproof roll material to the film-covering position 11; a hot-melt cutting mechanism 40, flexibly disposed on the frame 10, the hot-melt cutting mechanism 40 being located between the packaging film conveying mechanism 20 and the film-covering position 11; and a heat-shrinking chamber 50, disposed on the frame 10. On the frame 10, located on one side of the discharge end of the film-coating position 11; heat-shrinkable support balls 51 are disposed in the heat-shrinkable chamber 50, and there are four heat-shrinkable support balls 51 for supporting the waterproof membrane being coated; there are two sets of lifting mechanisms 52, which are respectively disposed above and below the heat-shrinkable support balls 51, and the lifting mechanisms 52 move closer to or away from the heat-shrinkable support balls 51 after lifting; upper and lower surface heat-shrinkable components 53 are disposed at the output end of the lifting mechanisms 52; a rapid cooling mechanism is also provided in the heat-shrinkable chamber 50.

[0040] In this embodiment, to solve the problem of the packaging bag sticking to the waterproof membrane, a heat shrink chamber 50 is provided on the frame 10 to facilitate the heat shrinking of the packaging bag on the outside of the waterproof membrane, so that the packaging bag film wraps the waterproof membrane. The rolled waterproof membrane is conveyed by the feeding mechanism 30 to one side of the packaging bag film at the feeding end of the laminating position 11. Then, the feeding mechanism 30 continues to move, driving the rolled waterproof membrane to move. The waterproof membrane contacts and presses the packaging bag, so that the packaging bag film wraps around the surface of the waterproof membrane, forming a "U" shape. Then, the hot melt cutting mechanism 40 is activated to press and hot melt the packaging bag film, so that the cut part is a cylindrical structure wrapped on the waterproof membrane, with both ends extending beyond the waterproof membrane. At both ends, the remaining packaging film is heat-cut and glued together to form a complete packaging film, which is convenient for the next wrapping. The wrapped waterproof membrane is transported into the heat shrink chamber 50 and falls on the heat shrink support ball 51. Then, the lifting mechanism 52 drives the upper and lower surface heat shrink components 53 to move up and down, so that the upper and lower surface heat shrink components 53 approach the waterproof membrane with packaging film on the heat shrink support ball 51, so that the packaging film on the outside of the waterproof membrane is evenly heated and shrinks, making the packaging film on the outside of the waterproof membrane complete and smooth, thus completing the packaging of the waterproof membrane. After the packaging is completed, the material is rapidly cooled by the rapid cooling mechanism, and then the packaged material is pushed out by the pushing mechanism. The system employs a ball-bearing support structure, minimizing the support area and reducing obstruction to heat shrinking. The upper and lower surface heat shrinking components evenly heat the material on the support balls, ensuring uniform heating and resulting in properly packaged material. Since the packaging film is not rolled during the heat shrinking process, it is less prone to wrinkles, adheres better to the material surface after packaging, and is easier to move. The film is also less likely to break due to wrinkles. Rapid cooling after heat shrinking effectively prevents continuous shrinkage of the film, whether in all areas or only partially. Continuous shrinkage from all sides can compress the material inside the film, potentially affecting its performance, while continuous shrinkage in certain areas can cause wrinkles on the film surface.

[0041] like Figures 1-2As shown, the heat shrink chamber 50 is also provided with two end heating plates 531. The two end heating plates 531 are respectively raised and lowered on both sides of the heat shrink chamber 50. The end heating plates 531 have a bowl-shaped structure. The upper and lower surface heat shrink components 53 are arc-shaped heating plates and are located at the output end of the lifting mechanism 52. In this embodiment, to prevent the ends of the waterproof membrane from sticking to the packaging bag, an end heating plate 531 is provided. Both the end heating plate 531 and the upper and lower surface heat shrinking components 53 are provided with hot air holes. A fan is installed on the inner wall (top and side walls) of the heat shrinking chamber 50. The fan blows airflow onto the end heating plate 531 and the upper and lower surface heat shrinking components 53, heating the airflow into hot air, which is then blown onto the waterproof membrane with the packaging bag film. This causes the packaging bag film to shrink onto the outside of the waterproof membrane. The upper and lower surface heat shrinking components 53 include two sets, ensuring uniform shrinkage of the packaging bag film on the outside of the waterproof membrane. The bowl-shaped end heating plates 531 at both ends are also adapted to the shape of the ends of the waterproof membrane, causing the packaging bag film at both ends to shrink to the same shape as the waterproof membrane, thus preventing the packaging bag film from sticking to the waterproof membrane. The heat shrinking support ball is connected to the frame at the bottom of the heat shrinking chamber via a support connecting frame.

[0042] like Figures 1-2 As shown, the lifting mechanism 52 includes a linear drive 521 disposed at the top and bottom of the heat shrink chamber 50. The output end of the linear drive 521 located at the top of the heat shrink chamber 50 passes through the top of the heat shrink chamber 50 and connects to the upper and lower surface heat shrink assembly 53 above the heat shrink support ball 51. The output end of the linear drive 521 located at the bottom of the heat shrink chamber 50 connects upward to the upper and lower surface heat shrink assembly 53 below the heat shrink support ball 51. A guide rail 522 is disposed on the side wall of the heat shrink chamber 50. The two ends of the upper and lower surface heat shrink assembly 53 are provided with grooves adapted to the guide rail 522.

[0043] In this embodiment, in order to ensure that the distance between the upper and lower surface heat shrinkable components 53 and the waterproof membrane and packaging film is appropriate, a linear drive 521 is provided on the outer wall of the top of the heat shrink chamber 50. Its output end extends into the heat shrink chamber 50 and is connected to the upper and lower surface heat shrinkable components 53. The linear drive 521 extends and drives the upper and lower surface heat shrinkable components 53 to move up and down and approach the waterproof membrane. The sliding groove of the upper and lower surface heat shrinkable components 53 is always on the guide rail 522, which ensures that the movement direction of the upper and lower surface heat shrinkable components 53 is accurate and will not deviate.

[0044] like Figures 1-2 As shown, the feeding mechanism 30 includes an active roller 31, which is rotatably mounted on the frame 10; and a push plate 32, which is oscillatingly mounted on the frame 10. After the push plate 32 oscillates, it moves closer to or further away from the film-coating position 11. A material width capture and detection camera 6 is provided above the feeding mechanism 30.

[0045] In this embodiment, in order to ensure the continuous conveying of the waterproof membrane, the feeding mechanism 30 includes an active roller 31 rotatably mounted on the frame 10. The active roller 31 rotates, driving the rolled waterproof membrane to move towards the laminating position 11. When the waterproof membrane contacts the packaging bag film at the feeding end of the laminating position 11, the push plate 32 swings to press the waterproof membrane against the packaging bag film and push it towards the laminating position 11, which facilitates subsequent hot cutting to cut the packaging bag film.

[0046] like Figures 1-2 As shown, the packaging film conveying mechanism 20 includes an upper film feeding roller 21, which is disposed on the frame 10 and located above the film covering position 11; a lower film feeding roller 22, which is disposed on the frame 10 and located below the film covering position 11; and two sets of clamping rollers 23, which are respectively located next to the upper film feeding roller 21 and the lower film feeding roller 22.

[0047] In this embodiment, rolls of packaging film are respectively fitted on the upper film feeding roller 21 and the lower film feeding roller 22. The ends of the two rolls of packaging film are glued together to form a whole roll. When the waterproof membrane is pushed by the push plate 32, the waterproof membrane presses the packaging film together and moves to the film covering position 11. The packaging film is pulled and smoothed along the clamping roller 23 to ensure the tension of the packaging film. This makes the packaging film wrapped on the waterproof membrane fit properly, avoids the packaging film from being too loose, reduces the length of packaging film used for each roll of waterproof membrane, and saves resources.

[0048] like Figures 1-2 As shown, the hot melt cutting mechanism 40 includes an upper cutter 41, which is raised and lowered on the frame 10 via an upper fixed seat 43; the upper fixed seat 43 is horizontally slidably connected to the frame 10; and a cutter seat 42, which is disposed on the frame 10. After the upper cutter 41 is raised and lowered, it approaches or moves away from the cutter seat 42. The hot-cutting surface of the cutter seat 42 is flush with the upper surface of the film-covering position 11. In this embodiment, in order to cut the portion of the packaging bag film wrapped on the waterproof membrane while keeping the remaining portion bonded as a whole, an upper cutter 41 is provided on the raised and lowered upper fixed seat 43. When the push plate 32 pushes the waterproof membrane onto the film-covering position 11, the upper fixed seat 43 descends, causing the upper cutter 41 to press against the cutter seat 42. The two work together to hot-cut and separate the packaging bag film.

[0049] like Figures 1-2 As shown, the upper cutter 41 is connected to the upper fixed seat 43 via an elastic element 44; the upper fixed seat 43 is connected to a punch 45, and the upper cutter 41 has a sliding hole 411. The punch 45 is slidably disposed in the sliding hole 411. The cutter seat 42 has a punching opening 421. After the punch 45 descends, it is pressed into the punching opening 421.

[0050] In this embodiment, in order to neatly separate the packaging film, an elastic element 44 is provided between the upper fixing seat 43 and the upper cutter 41. The elastic element 44 is a spring. When the upper fixing seat 43 moves down, the upper cutter 41 first contacts the cutter seat 42 and heat-melts the packaging film. The upper fixing seat 43 continues to press down, so that the upper fixing seat 43 presses the elastic element 44, and the punch 45 moves down and extends out of the lower surface of the upper cutter 41 and presses into the punch cut 421, completing the cutting of the heat-melt bonded part, so that the packaging film is separated.

[0051] like Figures 1-2 As shown, one end of the film-covering position 11 is hinged to the frame 10, and the other end is raised and lowered on the frame 10, with the raised end away from the hot-melt cutting mechanism 40. In this embodiment, in order to move the waterproof roll material containing the packaging bag film onto the heat-shrink support ball 51, the film-covering position 11 is hinged. During film wrapping, the output end of the film-covering position 11 is higher to prevent the waterproof roll material from pulling the packaging bag film, while the pushing plate 32 prevents it from falling back. After the hot-cutting blade completes the separation, the output end of the film-covering position 11 is lowered until the waterproof roll material with the packaging bag film slides down onto the heat-shrink support ball 51 due to its own weight, completing the subsequent heat-shrink packaging.

[0052] like Figures 1-2 As shown, the rapid cooling mechanism includes cooling air outlets 7 evenly distributed in the heat shrink chamber 50, a pusher plate 8 at one end of the heat shrink support ball 51, the pusher plate 8 being connected to the pusher cylinder 9, the other end of the heat shrink support ball 51 being the discharge end, the discharge end being provided with a discharge port 501, a flexible heat insulation curtain being provided at the discharge port 501, and a weighing mechanism 12 being provided at the discharge end.

[0053] After heat shrinking is completed, the end heating plate is lowered by the lifting cylinder to expose the discharge port. Then, the rapid cooling mechanism is turned on, and cold air is blown out from the cooling air outlet at the front of the heat shrink chamber. This can quickly reduce the temperature inside the heat shrink chamber. After cooling, the pushing cylinder is activated. Under the action of the pushing cylinder, the pushing plate moves towards the middle of the heat shrink chamber and pushes the processed material out of the discharge port, so that it falls onto the weighing mechanism outside the heat shrink chamber.

[0054] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
