Description

Technical Field

[0001] The invention relates to the technical field of packaging equipment, and in particular to packaging equipment for producing rock wool composite panels. Background Art

[0002] Rock wool composite board is a common building insulation material, which is mainly made of rock fiber after high-temperature melting. This material has good thermal insulation and sound insulation properties and is often used for insulation and sound insulation treatment of walls, roofs, floors and other parts of buildings. If the rock wool integrated board is exposed to a humid environment, the rock wool material inside it will absorb a lot of moisture, resulting in a decrease in thermal insulation performance, and may cause problems such as mold and corrosion, or to prevent physical damage during transportation, storage and installation, so it is necessary to package and coat both sides of the rock wool integrated board to isolate moisture from entering and prevent physical damage.

[0003] When the existing rock wool composite board is packaged, the initial plastic film coil has a large radius and a large moment of inertia. As the coil is gradually consumed, the radius continues to decrease and the linear speed becomes smaller. The packaging device usually operates at a relatively constant film coating and packaging speed. As the radius of the plastic film coil decreases, the actual linear speed of the film will gradually be lower than the set film coating speed. Due to the existence of this speed difference, the plastic film will be subjected to an additional tension during the forward conveyance. When this tension exceeds the limit that the plastic film itself can withstand, it will cause the plastic film to be unevenly stretched in the length direction, forming some gaps between the plastic film and the rock wool composite board, which will be filled with air to form bubbles during the packaging process, thereby affecting the overall packaging effect and appearance of the rock wool board. Summary of the invention

[0004] The object of the present invention is to provide a packaging device for producing rock wool composite panels to solve the problems raised in the above-mentioned background technology.

The vacuuming component can reduce incomplete adhesion or bubbling during coating, thereby improving the uniformity and quality of coating.

[0017] A second conveyor belt is arranged at one end of the workbench away from the placing frame, and the cutting knife is located between the first conveyor belt and the second conveyor belt.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The scraping component of the present invention can timely and effectively scrape off bubbles, making the packaging coating smoother.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figure 1-Figure 9The packaging equipment for producing rock wool composite panels shown in the figure comprises a workbench 1, a placing rack 2 is provided on one side of the workbench 1, a first conveyor belt 3 is provided at the bottom of the placing rack 2, and a scraping assembly is installed on one side of the first conveyor belt 3;

[0035] The scraping assembly is arranged at one end of the workbench 1 away from the placement rack 2, and the scraping assembly includes a driving component, an amplifying component and a scraping component. The driving component includes a driving rod 23. A placement box 22 is provided at one end of the workbench 1, and one end of the driving rod 23 extends through and extends to the interior of the placement box 22 and is slidably connected. The driving rod 23 is located at one end of the placement box 22 and is fixedly connected with a first trapezoidal block 24. A sliding groove is provided inside the placement box 22, and a second trapezoidal block 25 is slidably connected inside the sliding groove. The first trapezoidal block 24 is located on one side of the second trapezoidal block 25, and one end of the second trapezoidal block 25 is fixedly connected with a spring 27. A damper 26 is provided inside the spring 27, and the damper 26 is used to control the rebound speed of the spring 27.

[0036] By setting the scraping component, bubbles can be scraped off timely and effectively, and the packaging coating can be made smoother. Specifically, when the radius of the plastic film coil decreases during the packaging coating process, the actual linear speed of the film will gradually be lower than the set coating speed, and bubbles will appear on the packaging surface of the rock wool board. At this time, the scraper 15 will squeeze out the bubbles on the upper and lower sides of the rock wool board and press the plastic packaging film onto the rock wool board, thereby improving the appearance quality and packaging effect of the product.

[0037] like Figure 5-Figure 9 As shown, the enlargement component includes a first connecting rod 28, a limiting groove is provided at one end of the placement box 22, the second trapezoidal block 25 is rotatably connected to the first connecting rod 28, the first connecting rod 28 is slidably connected to the limiting groove, a fixing rod 29 is provided on the top of the workbench 1, one end of the fixing rod 29 is connected to a rotating rod 30 through a rotating shaft, the rotating shaft is located at the upper end of the rotating rod 30, the top of the rotating rod 30 is rotatably connected to the first connecting rod 28, the scraping assembly includes a second connecting rod 31 and a third connecting rod 32, the second connecting rod 31 and the third connecting rod 32 are respectively located on both sides of the rotating rod 30, and are rotatably connected to the rotating rod 30, two tracks 33 are provided at both ends of the workbench 1, a slide plate 34 is slidably connected to the interior of each track 33, a scraper 15 is provided on the inner side of each two slide plates 34, the second connecting rod 31 and the third connecting rod 32 are respectively rotatably connected to two of the slide plates 34, and a heat shrink plate 19 is provided on the opposite side of the two scrapers 15.

[0038] When the cutting blade 9 moves downward, the cylinder 13 drives the L-shaped plate 18 to move downward. At this time, the L-shaped plate 18 drives the driving rod 23 to move downward. The driving rod 23 moves downward and drives the first trapezoidal block 24 to move downward. When the first trapezoidal block 24 moves downward, it drives the second trapezoidal block 25 to move rightward inside the chute (according to Figure 6), when the second trapezoidal block 25 moves, it pushes the first connecting rod 28 to move forward inside the limiting groove, thereby driving the rotating rod 30 to rotate. Since the axis of the rotating rod 30 is located at the upper half of the rotating rod 30, the driving force of the cutting knife 9 is transmitted to the first connecting rod 28 to push the rotating rod 30 to move a smaller stroke, and the bottom of the rotating rod 30 will move a larger stroke, and then the bottom of the rotating rod 30 will push the slide 34 at the bottom of the second connecting rod 31 and the third connecting rod 32 to move a larger distance in the track 33. When the slide 34 moves, it drives the scraper 15 to move to remove the bubbles on the upper and lower sides of the rock wool board after the coating is completed, and the heat shrink plate 19 on the top of the scraper 15 transfers heat to the plastic film packaging of the rock wool board after the bubbles are scraped off, so that it shrinks to make up for the gaps left by the bubbles, thereby further improving the fit between the plastic packaging film and the rock wool board.

[0039] When the cutting blade 9 moves upward, the first trapezoidal block 24 moves upward, and the second trapezoidal block 25 is driven by the spring 27 to move to the left (according to Figure 6 ), the damper 26 slows down the rebound speed of the spring 27 by increasing the resistance, so as to achieve the effect that the second trapezoidal block 25 moves left and right at the same speed. When the second trapezoidal block 25 moves to the left, the scraper 15 will move in the opposite direction, so the up and down movement of the cutting knife 9 will drive the scraper 15 to move back and forth to remove the bubbles.

[0040] like Figure 1-Figure 3 As shown, a coating roller 7 is provided at one end of the first conveyor belt 3, a coiling roller 6 is provided at one side of the coating roller 7, a fixed plate 20 is provided at one end of the coiling roller 6, a cylinder 13 is provided at one end of the fixed plate 20, an L-shaped plate 18 is fixedly connected to the output end of the cylinder 13, a cutting knife 9 is provided at one end of the L-shaped plate 18, a driving rod 23 is fixedly connected to the L-shaped plate 18, a bottom plate 21 is provided on the side of the fixed plate 20 away from the cylinder 13, the bottom plate 21 is located directly below the heat shrink plate 19, and a dust collection assembly is provided above the placement rack 2.

[0041] The coating roller 7 is used to package and coat the upper and lower sides of the rock wool board, and the cutting knife 9 is used to cut the continuous film on one side of the coated rock wool board so as to carry out the next coating.

[0042] like Figure 3-Figure 4As shown, the dust collection component includes a motor 4, the output end of the motor 4 is connected to a reciprocating screw 5 through two bevel gears, two plates are provided on the top of the placement frame 2, the two ends of the reciprocating screw 5 are respectively rotatably connected to the two plates, the outer wall of the reciprocating screw 5 is threadedly connected to a slider 8, both ends of the slider 8 are fixedly connected to a limit block 12, the top of the placement frame 2 is fixedly connected to two slide rails 11, the two limit blocks 12 are respectively slidably connected to the corresponding slide rails 11, the dust collection component also includes a dust collector 10, the dust collector 10 is located at the bottom of the slider 8, the bottom of the dust collector 10 is connected to a connecting plate 16, and the four ends of the connecting plate 16 are connected to suction ports 17.

[0043] When the rock wool board is coated and packaged, the rock wool board is manually placed under the vacuum cleaner 10, and one side of the rock wool board is vacuumed first. After vacuuming one side, the rock wool board is placed on the first conveyor belt 3, and the rock wool board on the other side is vacuumed through the suction port 17. After vacuuming, the rock wool board is transported by the first conveyor belt 3 to one end of the coating roller 7 for coating and packaging, which can reduce incomplete adhesion or bubbling during coating, thereby improving the uniformity and quality of the coating.

[0044] After packaging is completed, it is sent to the side of the cutting knife 9, and the cutting knife 9 is driven by the cylinder 13 to cut the continuous film on one side of the rock wool board so as to carry out the next film coating;

[0045] The motor 4 and the reciprocating screw 5 can drive the vacuum cleaner 10 to move so as to adapt to longer rock wool boards. When the rock wool board is too long, the motor 4 can drive the reciprocating screw 5 to rotate, thereby driving the suction port 17 at the bottom of the vacuum cleaner 10 to move, so that the suction port 17 can completely cover and process the surface of the rock wool board, more effectively remove dust, debris or other pollutants on the surface of the longer rock wool board, and improve applicability.

[0046] like Figure 1-Figure 3 As shown, a second conveyor belt 14 is provided at one end of the workbench 1 away from the placement rack 2 , and the cutting knife 9 is located between the first conveyor belt 3 and the second conveyor belt 14 .

[0047] Working principle: During packaging, the rock wool board is manually placed under the vacuum cleaner 10, and one side of the rock wool board is vacuumed first. After vacuuming one side, the rock wool board is placed on the first conveyor belt 3, and the rock wool board on the other side is vacuumed through the suction port 17. After vacuuming, it is transported to one end of the coating roller 7 by the first conveyor belt 3 for coating packaging. After packaging, it is sent to one side of the cutting knife 9, and the cutting knife 9 is driven downward by the cylinder 13 to cut the continuous film on one side of the rock wool board. When the cutting knife 9 moves downward, the cylinder 13 will drive the L-shaped plate 18 to descend. At this time, the L-shaped plate 18 drives the driving rod 23 to move downward, and the driving rod 23 moves downward to drive the first trapezoidal block 24 to move downward. When the first trapezoidal block 24 moves downward, it drives the second trapezoidal block 25 to move to the right inside the chute (according to Figure 6 When the second trapezoidal block 25 moves, it pushes the first connecting rod 28 to move forward inside the limiting groove, thereby driving the rotating rod 30 to rotate. Since the axis of the rotating rod 30 is located at the upper half of the rotating rod 30, the driving force of the cutting knife 9 is transmitted to the first connecting rod 28 to push the rotating rod 30 to move a smaller stroke, and then the bottom of the rotating rod 30 will push the slide plate 34 at the bottom of the second connecting rod 31 and the third connecting rod 32 to move a larger distance in the track 33. When the slide plate 34 moves, it drives the scraper 15 to move, and removes the bubbles on the upper and lower sides of the rock wool board after the coating is completed. The heat shrink plate 19 on the top of the scraper 15 transfers heat to the plastic film packaging of the rock wool board after the bubbles are scraped off, so that it shrinks to make up for the gap left by the bubbles, thereby further improving the fit between the plastic packaging film and the rock wool board. When the cutting knife 9 moves up, the first trapezoidal block 24 moves up. At this time, the second trapezoidal block 25 is driven by the spring 27 to move to the left (according to Figure 6 ), the damper 26 slows down the rebound speed of the spring 27 by increasing the resistance, so as to achieve the effect that the second trapezoidal block 25 moves left and right at the same speed. When the second trapezoidal block 25 moves to the left, the scraper 15 will move in the opposite direction, so the up and down movement of the cutting knife 9 will drive the scraper 15 to move back and forth. After the scraper 15 removes the bubbles, the rock wool board is transported to the second conveyor belt 14 for subsequent boxing and other operations.
