Abstract
Description
Technical Field
[0001] The embodiments of this utility model relate to the field of glass wool production technology, specifically to a dustproof bag pressing machine for glass wool production. Background Technology
[0002] Glass wool is widely used in many fields such as construction and industrial insulation as a high-quality insulation, heat insulation, and sound absorption material. To ensure that the quality of glass wool products is not affected during production, storage, and transportation, proper packaging is an indispensable and crucial step in the production process.
[0003] In the packaging process of glass wool products, to prevent dust and other impurities from contaminating the glass wool, a dustproof film is usually applied to both the top and bottom surfaces of the product. The width of the dustproof film is greater than the width of the glass wool, allowing the protruding parts to be pre-applied with adhesive. The two layers of dustproof film are then bonded together using the adhesive edges, forming a complete dust bag covering the glass wool. This type of dust bag effectively blocks dust during the storage and transportation of the glass wool, protecting its cleanliness and maintaining its optimal performance.
[0004] However, in actual production, it was found that after the upper and lower dustproof films are bonded together to form a dustproof bag, air tends to accumulate in the gaps between the glass wool and the dustproof bag. This accumulated air can prevent the dustproof bag from tightly adhering to the glass wool, affecting the degree to which the dustproof bag adequately covers the glass wool.
[0005] Therefore, how to effectively solve the problem of air accumulation between the side of glass wool and the dust bag, and improve the degree of coverage of glass wool by the dust bag, has become a key technical problem that urgently needs to be solved in the glass wool production and packaging process. This is of great significance for improving the quality of glass wool products, reducing production costs, and enhancing market competitiveness. Utility Model Content
[0006] To overcome the above-mentioned defects, embodiments of this utility model provide a dustproof bag pressing machine for glass wool production, which solves the technical problem in the related art that air easily accumulates in the gap between the side of the glass wool and the dustproof bag.
[0007] According to one aspect, at least one embodiment of the present invention provides a dustproof bag pressing machine for glass wool production, including a frame, a conveyor belt, a support frame and an arc-shaped pressing plate. The conveyor belt is disposed on the frame and is used to convey glass wool with a dustproof film covering its surface. The width of the dustproof film is greater than the width of the glass wool so that the side of the dustproof film can protrude from the side of the glass wool. The support frame includes vertical rods, horizontal rods, and longitudinal rods. The vertical rods are mounted on the frame, the horizontal rods are mounted on the vertical rods, and the longitudinal rods are mounted on the horizontal rods. The arc-shaped pressure plate is located at the end of the longitudinal rod and is positioned above the side of the glass wool to flatten the portion of the dustproof membrane protruding from the side of the glass wool. The horizontal bar can slide up and down along the vertical bar to adjust the height of the arc-shaped pressure plate, and the vertical bar can slide laterally along the horizontal bar to adjust the lateral position of the arc-shaped pressure plate.
[0008] For example, in at least one embodiment of the present invention, a dustproof bag pressing machine for glass wool production further includes: It also includes a locking block, which has two mounting holes perpendicular to each other in the axial direction. The crossbar and the vertical bar are respectively installed in the two mounting holes one by one, and both the crossbar and the vertical bar can slide in the corresponding mounting holes.
[0009] For example, in at least one embodiment of the present invention, a dustproof bag pressing machine for glass wool production further includes: A support roller is rotatably mounted on the frame, and a pressure roller is rotatably mounted above the support roller. Glass wool is passed between the support roller and the pressure roller. The pressure roller is used to flatten the dustproof film on the top surface of the glass wool, and the support roller is used to flatten the dustproof film on the bottom surface of the glass wool.
[0010] For example, in at least one embodiment of the present invention, a dustproof bag pressing machine for glass wool production further includes: A lifting frame is vertically slidably mounted on the frame, and the pressure roller is rotatably mounted on the lifting frame. A linear drive component is provided between the lifting frame and the frame.
[0011] For example, in at least one embodiment of the present invention, a dustproof bag pressing machine for glass wool production further includes: The frame is equipped with a suspension above the conveyor belt. A support shaft is provided at the bottom of the suspension, and two swing arms are hinged to the support shaft. Each swing arm is equipped with an air knife, which is used to blow away the dustproof film on the surface of the glass wool.
[0012] For example, in at least one embodiment of the present invention, a dustproof bag pressing machine for glass wool production further includes: Each of the two swing arms is rotatably equipped with a rotating block, and a bidirectional screw is connected between the two rotating blocks. The two ends of the bidirectional screw are threadedly connected to the two rotating blocks respectively.
[0013] For example, in at least one embodiment of the present invention, a dustproof bag pressing machine for glass wool production further includes: Both of the swing arms are rotatably equipped with mounting frames, and each mounting frame is rotatably equipped with a support roller, which is used to abut against the surface of the glass wool and roll along the surface of the glass wool.
[0014] For example, in at least one embodiment of the present invention, a dustproof bag pressing machine for glass wool production further includes: A telescopic rod is connected between the two mounting brackets, and the telescopic rod is arranged perpendicular to the conveying direction.
[0015] The beneficial effects of the embodiments of this utility model are as follows: In this invention, when the glass wool covered with a dustproof film is conveyed by a conveyor belt to the area under the arc-shaped pressure plate, the arc-shaped pressure plate applies pressure to the part of the dustproof film protruding from the side of the glass wool. The air between the dustproof film and the side of the glass wool is squeezed and thus discharged, allowing the dust bag to fit tightly against the glass wool and improving the degree of coverage of the glass wool by the dust bag.
[0016] The curved design of the pressure plate serves as a guide. During glass wool conveying, the sides of the glass wool pass along the curvature of the pressure plate without obstruction, ensuring smooth conveying. The height of the curved pressure plate can be adjusted by adjusting the height of the crossbar on the vertical bar, maintaining a suitable distance from the surface of the glass wool to effectively flatten the dustproof film. The lateral position of the vertical bar on the horizontal bar can be adjusted to ensure the curved pressure plate is accurately positioned above the sides of the glass wool, adapting to glass wool products of different widths.

[0026] like Figures 1-6 The diagram illustrates a dustproof bag pressing machine for producing glass wool, according to one embodiment of the present invention. The machine includes a frame 1, a conveyor belt 2, a support frame 3, and an arc-shaped pressure plate 4. The frame 1 is the basic supporting structure of the entire pressing machine. The conveyor belt 2 is mounted on the frame 1 and is responsible for conveying glass wool with a dustproof film covering its surface. The width of the dustproof film is greater than the width of the glass wool, allowing the sides of the dustproof film to protrude beyond the sides of the glass wool. In the support frame 3, vertical rods 5 are mounted on the frame 1, perpendicular to the ground; horizontal rods 6 are mounted horizontally on the vertical rods 5; and longitudinal rods 7 are mounted on the horizontal rods 6. The arc-shaped pressure plate 4 is mounted at the end of the longitudinal rods 7, located above the sides of the glass wool. The arc-shaped pressure plate 4 can flatten the portion of the dustproof film protruding from the sides of the glass wool, thereby expelling internal air.
[0027] Working principle: When the glass wool covered with a dustproof film is conveyed by the conveyor belt 2 to the area under the arc-shaped pressure plate 4, the arc-shaped pressure plate 4 applies pressure to the part of the dustproof film that protrudes from the side of the glass wool. The air between the dustproof film and the side of the glass wool is squeezed and thus discharged, so that the dustproof bag can fit tightly against the glass wool, improving the degree of coverage of the glass wool by the dustproof bag.
[0028] The arc-shaped design of the curved pressure plate 4 serves as a guide. During the glass wool conveying process, the side of the glass wool passes along the arc of the curved pressure plate 4 without obstruction, ensuring smooth conveying of the glass wool. The height of the curved pressure plate 4 can be adjusted by adjusting the height of the crossbar 6 on the vertical bar 5, so that it can maintain a suitable distance from the surface of the glass wool, thereby effectively flattening the dustproof film; the lateral position of the vertical bar 7 on the crossbar 6 can be adjusted so that the curved pressure plate 4 can be accurately positioned above the side of the glass wool, achieving adaptation to glass wool products of different widths.
[0029] In some examples, such as Figure 3 , 4 As shown, the locking block 8 has two vertical mounting holes 9, and the crossbar 6 and the longitudinal bar 7 are respectively installed in the two mounting holes 9.
[0030] Working principle: The locking block 8 ensures the connection between the horizontal bar 6 and the vertical bar 7. Since the horizontal bar 6 and the vertical bar 7 can slide within their corresponding mounting holes 9, the operator can adjust the relative positions of the horizontal bar 6 and the vertical bar 7 according to actual needs, thereby adjusting the position of the arc-shaped pressure plate 4. When the arc-shaped pressure plate 4 is not in use, the operator can take advantage of the rotatable characteristic of the vertical bar 7 within the mounting hole 9 to manually rotate the vertical bar 7, causing the connected arc-shaped pressure plate 4 to rotate, thereby lifting the arc-shaped pressure plate 4, facilitating the organization and maintenance of the equipment when it is not in operation.
[0031] In some examples, such as Figure 1 As shown, a support roller 10 is rotatably mounted on the frame 1. The length of the support roller 10 is greater than the width of the glass wool to ensure full support of the bottom surface of the glass wool. The support roller 10 supports the bottom surface of the glass wool and flattens the dustproof film, preventing wrinkles or bulges in the bottom dustproof film. A pressure roller 11 is rotatably mounted above the support roller 10, forming a channel for the glass wool to pass through. The function of the pressure roller 11 is to flatten the dustproof film on the top surface of the glass wool, making it tightly adhere to the glass wool. A lifting frame 12 is vertically slidable on the frame 1. The pressure roller 11 is rotatably mounted on the lifting frame 12. When the lifting frame 12 moves up and down, the pressure roller 11 rises and falls accordingly, thereby adjusting the gap between the pressure roller 11 and the support roller 10. A linear drive component is provided between the lifting frame 12 and the frame 1. The linear drive component can be an electric push rod, a hydraulic cylinder, or a pneumatic cylinder, etc.
[0032] Working principle: When the glass wool passes between the support roller 10 and the pressure roller 11, the pressure roller 11 and the support roller 10 work together to flatten the dustproof film on the upper and lower surfaces of the glass wool simultaneously. The dustproof film adheres tightly to the upper and lower surfaces of the glass wool, squeezing out any air that may be present, making the dustproof film more evenly cover the glass wool, effectively improving the covering quality of the dust bag. When processing glass wool of different thicknesses, the linear drive component drives the lifting frame 12 to rise or fall according to the thickness of the glass wool. The lifting frame 12 drives the pressure roller 11 to move synchronously, thereby adjusting the gap between the pressure roller 11 and the support roller 10 to adapt to glass wool products of different thicknesses.
[0033] In some examples, such as Figure 1 , 2 As shown in Figures 5 and 6, a suspension 13 is installed on the frame 1, located above the conveyor belt 2, providing a mounting base for components such as the support shaft 14, swing arms 15, and air knives 16. The support shaft 14 is located at the bottom of the suspension 13, and the ends of both swing arms 15 are hinged to the support shaft 14, allowing the swing arms 15 to oscillate around the support shaft 14. Each of the two swing arms 15 is equipped with an air knife 16, which is installed along the length of the swing arm 15, with its air outlet facing the dustproof film on the surface of the glass wool. The air knife 16 connects to an external air source to blow air out evenly and at high speed; the air outlet of the air knife 16 is elongated and slender.
[0034] Each of the two swing arms 15 is rotatably equipped with a rotating block 17, and a bidirectional screw 18 connects the two rotating blocks 17. The two ends of the bidirectional screw 18 are threadedly connected to the two rotating blocks 17 respectively. The threads at the two ends of the bidirectional screw 18 turn in opposite directions. When the bidirectional screw 18 rotates, the two rotating blocks 17 connected to it can move synchronously towards or away from each other, thereby causing the two swing arms 15 to swing towards or away from each other. A locking bolt can be threaded onto the suspension 13. The locking bolt tightens the swing arms 15, preventing them from swinging on their own under normal conditions. When the angle of the swing arms 15 needs to be adjusted, the locking bolt can be loosened.
[0035] Working principle: When the glass wool moves on the conveyor belt 2, the high-speed airflow blown by the air knife 16 acts on the dustproof film on the surface of the glass wool, helping to eliminate any wrinkles in the dustproof film and preventing air accumulation, thereby further improving the adhesion between the dustproof film and the surface of the glass wool. When it is necessary to adjust the blowing angle of the air knife 16, the operator rotates the bidirectional screw 18, causing the two rotating blocks 17 to move synchronously towards or away from each other. The rotating blocks 17 drive the swing arm 15 to swing around the support shaft 14, thereby changing the blowing angle of the air knife 16.
[0036] In some examples, such as Figure 5 , 6 As shown, mounting brackets 19 are rotatably mounted on both swing arms 15, and the mounting brackets 19 are used to mount support rollers 20. The support rollers 20 are rotatably mounted on the mounting brackets 19. During the glass wool conveying process, the support rollers 20 abut against the surface of the glass wool and roll along its surface as the glass wool moves, thus supporting the swing arms 15.
[0037] A telescopic rod 21 connects the two mounting brackets 19 on the two swing arms 15. The telescopic rod 21 is set perpendicular to the conveying direction of the glass wool. When the swing arms 15 swing due to the rotation of the bidirectional screw 18, the distance between the two mounting brackets 19 changes. Since the telescopic rod 21 is perpendicular to the conveying direction and its two ends are hinged to the mounting brackets 19, it can extend or shorten accordingly according to the swing amplitude of the swing arms 15, ensuring that the axis of the support roller 20 is always perpendicular to the conveying direction after the swing arms 15 swing. This allows the support roller 20 to continuously roll normally along the surface of the glass wool, stably providing support for the swing arms 15.
[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
