Description

Technical Field

[0001] This invention relates to the field of waterproof material processing technology, specifically a waterproof roll film application device. Background Technology

[0002] Waterproof membrane is a flexible building material that can be rolled up and used in building walls, roofs, tunnels, highways, landfills, etc., to resist external rainwater and groundwater seepage. It has waterproof performance and durability and is used to protect building structures or underground structures from water penetration and damage. Its materials are mainly flexible polymer modified bitumen, polyethylene, polypropylene, etc. Among them, self-adhesive polymer modified bitumen polyester-based waterproof membrane is widely used in waterproofing projects. The waterproof membrane application device is a machine used to attach an anti-stick film to the surface of the waterproof membrane. When the film needs to be applied, the anti-stick film needs to be removed from the roll or reel and conveyed to the surface of the object to be applied through a conveying system.

[0003] In the production of self-adhesive polymer-modified bitumen polyester waterproof membrane, an anti-adhesive film needs to be applied to the adhesive surface to prevent damage during the rolling process. During the application of the anti-adhesive film to the waterproof membrane, auxiliary devices such as rollers or spraying devices are needed to ensure uniform application of the anti-adhesive film. Once the anti-adhesive film reaches the surface of the object, it is adhered or pressed to ensure good contact and adhesion.

[0004] However, in actual processing, it is difficult to achieve completely accurate positioning of the rollers. Inaccurate roller positioning makes it difficult to control the positioning accuracy of the anti-adhesive film during the lamination process, resulting in the anti-adhesive film and the waterproof membrane not being on the same straight line. The misalignment of the anti-adhesive film and the waterproof membrane leads to a decrease in the overlap rate between them, resulting in material waste and insufficient processing accuracy.

[0005] To address this, existing technologies offer several solutions. These include adding a limiting device during the application of the waterproof membrane to ensure that the membrane and the roller are on the same axis. However, these solutions fail to resolve the roller eccentricity problem caused by inaccurate roller positioning.

[0006] In view of this, in order to overcome the above-mentioned technical problems, the present invention designs a waterproof roll film application device, which solves the above-mentioned technical problems. Summary of the Invention

[0007] The present invention provides a waterproof membrane laminating device that, by adaptively adjusting the positions of the waterproof membrane and the anti-adhesive membrane, drives the pressure roller to move and center, thus solving the problem of low overlap between the anti-adhesive membrane and the waterproof membrane during the lamination process of self-adhesive polymer modified bitumen polyester waterproof membrane.

[0008] The technical solution of this invention is as follows: a waterproof membrane applicator includes a positioning component, a leveling mechanism, a pressure roller, and air guide needles. The positioning component is equipped with a leveling mechanism for adjusting the distance between the positioning component and the material. The leveling mechanism drives the positioning component to move through its own motion control motor, thereby preventing the normal distance between the positioning component and the waterproof membrane from being too far, which would cause inaccurate initial positioning of the waterproof membrane. The function of the positioning component is to adjust the applicator speed according to the movement of the leveling mechanism. The positioning component and the leveling mechanism move synchronously, so that when the leveling mechanism needs to stop leveling the anti-adhesive membrane, the positioning component does not move and ensures that the anti-adhesive membrane and the waterproof membrane are on the same axis. A pressure roller is installed on the side of the positioning component away from the leveling mechanism, and the support point of the pressure roller... On a frame, to enable the pressure roller to adapt to waterproof membranes of different sizes and specifications, the connection between the pressure roller and the frame is a detachable fixed connection. The pressure roller adjusts its position with the movement of the positioning component, thereby preventing the pressure roller's own installation tolerance from being too large, which would lead to inaccurate positioning of the waterproof membrane. At the same time, it prevents the pressure roller from being subjected to radial force in the eccentric direction during the extension of the anti-adhesive membrane, which would cause instability in the connection between the pressure roller and the frame. An air guide needle is installed on one side of the leveling mechanism, and a vertical rod is set on the side of the air guide needle near the leveling mechanism. The vertical rod changes the position of the air guide needle relative to the material through the movement of the leveling mechanism, thereby realizing the reciprocating movement of the air guide needle with the leveling mechanism. The function of the air guide needle is to remove air bubbles with the leveling mechanism, thereby improving the overlap rate between the anti-adhesive membrane and the waterproof membrane.

[0009] Preferably, the positioning assembly includes a crossbar, a rocker arm, a lever, a gear and rack mechanism, a push plate, a clamping block, a shaft cylinder, and a protective rod. The crossbar is hinged to two rocker arms, with their rotation centers located at points a and b respectively, thus enabling power transmission between the rocker arms. A lever is hinged to the end of each rocker arm away from the crossbar. A leveling mechanism is installed on the crossbar, allowing the crossbar and leveling mechanism to move synchronously. The crossbar adjusts the film application rate through the movement of the leveling mechanism, ensuring that the positioning assembly stops moving after the leveling mechanism detects defects such as bubbles, preventing damage to the anti-adhesive film from wrinkles. A gear and rack mechanism is slidably connected to the crossbar via a groove. The rocker arm on one side of the rack pushes the rack, causing the gear to rotate around its own axis. The rotation of the gear along its own axis is converted into rotation around a line parallel to the gear's radial direction by a bevel gear set. The rack drives the rocker arm on the other side to move, thus... The lever swings, and a push plate is fixedly connected to the end of the lever away from the swing arm. The push plate positions the pressure roller by pushing the gear and rack mechanism. The rotation of the gear is converted into the axial rotation of the pressure roller through the bevel gear set, thereby enabling the pressure roller to move when the waterproof membrane deviates, thus achieving the positioning of the pressure roller. A clamping block for preventing material deviation is fixedly connected to the side of the push plate away from the pressure roller. The pressure roller is fixedly connected to a shaft cylinder, and a protective rod is slidably connected to the shaft cylinder through a slide groove. The end of the protective rod away from the shaft cylinder is hinged to the shaft of the bevel gear set, thereby enabling the gear and rack mechanism to control the extension of the protective rod under the drive of the push plate. The protective rod centers the pressure roller through the movement of the gear and rack mechanism, thereby automatically positioning the pressure roller when the connection between the pressure roller and the frame fails and the waterproof membrane deviates. The clamping block is equipped with a control element, which controls the electric push rod fixed on the cross rod to return the waterproof membrane to the correct position.

[0010] When applying a waterproof membrane, first lay the membrane flat on both sides of the crossbar, with the crossbar 1-2mm away from the normal direction of the membrane. When the waterproof membrane and the anti-adhesive membrane are not aligned, the push plate drives the lever to swing, which in turn drives the swing arm to swing. This, in turn, through the sliding of the gear and rack mechanism on the crossbar, drives the push plate on the other side of the crossbar to move. The push plate drives the clamping block to move the waterproof membrane until the membrane and the anti-adhesive membrane are on the same axis. Due to the movement of the rack, the gear meshing with the rack rotates synchronously, which in turn drives the shaft cylinder to rotate through the bevel gear set. The rotation of the shaft cylinder drives the protective rod to rotate, thus centering the membrane roller. The movement of the crossbar drives the leveling mechanism to move, achieving synchronous movement between the crossbar and the leveling mechanism.

[0011] Preferably, the end of the air guide needle near the leveling mechanism is rectangular, thereby improving the smoothness of the air guide needle insertion between the anti-adhesive membrane and the waterproof membrane. The shape of the axial section of the air guide needle is conical, thereby increasing the flow rate of gas in the air bubble between the waterproof membrane and the anti-adhesive membrane. The function of the air guide needle is to change the flow rate of gas in the air guide needle with the movement of the leveling mechanism, thereby accelerating the leveling speed of the air bubble.

[0012] Preferably, a centering groove is provided on the inner wall of the pressure roller, and a limiting piece is provided in the centering groove to prevent the pressure roller from deviating. The function of the limiting piece is to control the distance between itself and the guard rod as the leveling mechanism moves, thereby improving the stability of the centering effect of the guard rod on the pressure roller. The limiting piece is welded to the inner wall of the centering groove. When the guard rod and the centering groove are engaged, it prevents the rotation of the guard rod itself from causing the guard rod to separate from the centering groove, thereby realizing the stable control of the position of the pressure roller by the guard rod.

[0013] Preferably, the leveling mechanism includes a horizontal support rod, a sliding strip, an electric component, a rotating disk, a pusher plate, a positioning shaft, a spiral groove, and a leveling plate. A crossbar is fixedly connected to the horizontal support rod, and the crossbar and horizontal support rod move synchronously, thereby adjusting the film application rate of the pressure roller. This prevents the pressure roller from continuing to apply film while the air guide needle is moving, which could lead to wrinkles or folds in the anti-adhesive film. A limit rod is fixedly connected to the horizontal support rod near the crossbar. The limit rod is interference-fitted with the shaft cylinder, thereby positioning the pressure roller and ensuring a consistent distance between the pressure roller and the waterproof membrane, improving the film application effect. A sliding strip is slidably connected to the horizontal support rod via a groove. The function of the sliding strip is to control the distance between the crossbar and the material via the horizontal support rod. A limit block is provided at the connection between the sliding bar and the horizontal support rod to prevent the sliding bar from detaching from the horizontal support rod during sliding. A spherical block is hinged to the lower end of the sliding bar. The spherical block pushes the gas into the air guide needle by squeezing the air bubble, thereby changing the gas flow rate in the air guide needle and improving the working effect of the air guide needle. At the same time, the rolling phase has a more accurate effect in determining the position of the air bubble than the cylindrical rod. An electric component is installed within the stroke of the sliding bar. This electric component is an electric push rod. The sliding bar controls the start or stop of the electric component by changing its position relative to the material, thereby realizing the movement of the electric component when the sliding bar moves. The electric component is fixedly connected to a rotating disk. The electric component is triggered by the sliding bar to push the rotating disk to move.

[0014] A suction pipe is fixedly connected to the end of the rotating disk near the air guide pipe, and a guide needle is fixedly connected to the end of the suction pipe away from the shaft. The suction pipe absorbs gas from the guide needle through the rotation of the shaft. The suction pipe is a flexible tube with holes. When the suction pipe rotates with the rotating disk, the rotating disk squeezes the suction pipe, and the gas in the suction pipe is discharged through the holes, thereby improving the air-removing effect of the guide needle. Push plates are arranged circumferentially on the rotating disk. The function of the push plates is to control the synchronous movement of the guide needle and the rotating disk. The rotation of the push plates pushes the vertical rod to move, thereby causing the guide needle to change its distance relative to the material, thus realizing the reciprocating movement of the guide needle. The rotating disk is slidably connected to a positioning shaft via a sliding groove. The positioning shaft has a spiral groove that fits the rotating disk with a clearance, thereby changing the stroke range of the air guide needle. This allows the rotating disk to rotate simultaneously with the movement of the electric component. A flat plate is fixedly connected to the horizontal support rod, and a scraper is fixedly connected to the bottom of the flat plate. The scraper squeezes the gas at the air guide tube opening, thereby preventing the gas in the air guide tube from flowing back and achieving unidirectional flow of gas within the bubble. The scraper then compresses the bubble, further achieving unidirectional flow of gas within the bubble and preventing the gas from flowing back after extraction, which would cause the bubble to remain and thus prevent damage to the anti-adhesion membrane.

[0015] When waterproof membrane needs to be applied, the horizontal support rod moves with the cross rod, and the sliding rod moves in the axial position of the waterproof membrane. When there are air bubbles between the waterproof membrane and the anti-adhesive film, the sliding strip is lifted, which in turn controls the electric component to move and push the rotating disk to move. The spiral groove on the positioning shaft is fitted with the rotating disk with a clearance, so the rotating disk moves while rotating with the positioning shaft, which in turn drives the air extraction pipe to rotate. During the rotation of the air extraction pipe, the air extraction pipe is gradually squeezed and the gas inside the pipe is discharged. When the air guide needle moves away from the waterproof membrane, the flat plate moves with the cross rod, and the scraper set on the lower surface of the flat plate moves to level it.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. A waterproof membrane laminating device of the present invention, which adapts to the positions of the waterproof membrane and the anti-adhesive film, thereby driving the pressure roller to move and center, and then utilizes the synchronous movement of the positioning component and the leveling mechanism to improve the installation accuracy of the pressure roller, thereby achieving the effect of improving the overlap rate between the anti-adhesive film and the waterproof membrane during the waterproof membrane laminating process.

[0018] 2. A waterproof membrane applicator of the present invention utilizes the principle that the fluid flow rate is constant and the flow velocity is inversely proportional to the cross-sectional area. By cooperating with the air guide needle and the leveling mechanism, the gas in the air guide needle is allowed to flow in one direction, thereby achieving unidirectional flow of gas in the air bubbles between the waterproof membrane and the anti-adhesive membrane, thus improving the overlap rate between the anti-adhesive membrane and the waterproof membrane.

[0019] 3. A waterproof membrane applicator of the present invention automatically detects air bubbles between the waterproof membrane and the anti-adhesive membrane, and then uses the alternating movement of the air guide needle and the leveling mechanism to squeeze and seal the air bubbles between the waterproof membrane and the anti-adhesive membrane, preventing gas backflow and causing gas to re-enter between the waterproof membrane and the anti-adhesive membrane.

[0031] The present application will now be described more fully with reference to the accompanying drawings of illustrative embodiments. However, the present application may be implemented in various forms and should not be construed as limited to the embodiments given herein. The above-described embodiments are intended to make the disclosure herein comprehensive and to more fully convey the scope of protection of the present application to those skilled in the art. In this specification, terms such as "comprising" and "including" indicate that the technical solution of the present application does not exclude the presence of other units and steps not directly or explicitly stated, in addition to those units and steps directly and explicitly stated in the specification and claims.

[0032] like Figure 1-9As shown, a waterproof membrane applicator includes a positioning component 1 equipped with a leveling mechanism 2 for adjusting the distance between the positioning component 1 and the material. The leveling mechanism 2 uses its own motion control motor to drive the positioning component 1, thereby preventing the normal distance between the positioning component 1 and the waterproof membrane from becoming too far, which would cause inaccurate initial positioning of the waterproof membrane. The function of the positioning component 1 is to adjust the applicator speed according to the movement of the leveling mechanism 2. The positioning component 1 and the leveling mechanism 2 move synchronously. When the leveling mechanism 2 needs to stop leveling the anti-adhesive membrane, the positioning component 1 does not move, ensuring that the anti-adhesive membrane and the waterproof membrane are on the same axis. A pressure roller 3 is installed on the side of the positioning component 1 away from the leveling mechanism 2. The support point of the pressure roller 3 is on a frame. To enable the pressure roller 3 to adapt to different... The waterproof membrane of various sizes is connected to the frame by a detachable fixed connection of the pressing roller 3. The pressing roller 3 adjusts its position with the movement of the positioning component 1, thereby preventing the pressing roller 3 from being too large in its installation tolerance, which would lead to inaccurate positioning of the waterproof membrane. At the same time, it prevents the pressing roller 3 from being subjected to radial force in the eccentric direction during the extension of the anti-adhesive membrane, which would cause the connection between the pressing roller 3 and the frame to be unstable. An air guide needle 4 is installed on one side of the leveling mechanism 2. A vertical rod 41 is set on the side of the air guide needle 4 near the leveling mechanism 2. The vertical rod 41 changes the position of the air guide needle 4 relative to the material through the movement of the leveling mechanism 2, thereby realizing the reciprocating movement of the air guide needle 4 with the leveling mechanism 2. The function of the air guide needle 4 is to remove air bubbles with the leveling mechanism 2, thereby improving the overlap rate between the anti-adhesive membrane and the waterproof membrane.

[0033] When waterproof membrane needs to be applied, the motor drives the conveyor belt to move, which in turn drives the leveling mechanism 2 to move. The leveling mechanism 2 drives the positioning component 1 to move, completing the application process. During this process, the membrane on the pressure roller 3 rotates. The gravity on the pressure roller 3 changes continuously, causing the axial position of the pressure roller 3 to change continuously. When an air bubble is encountered, the leveling mechanism 2 drives the air guide needle 4 to move, thereby releasing the gas inside the air bubble. Then the leveling mechanism continues to move, completing the application process.

[0034] While existing technologies also include devices in the waterproof membrane application process that use limiting mechanisms to ensure the waterproof membrane and rollers are on the same axis, they fail to solve the problem of roller eccentricity caused by inaccurate roller installation.

[0035] like Figure 1-5As shown, the cross rod 11 is hinged to two rocker arms 12, with the rotation centers of the two rocker arms 12 located at points a and b respectively, thus realizing the mutual transmission of power between the rocker arms 12. A lever 13 is hinged to the end of the rocker arm 12 away from the cross rod 11. A leveling mechanism 2 is installed on the cross rod 11, thus the cross rod 11 and the leveling mechanism 2 move synchronously. The cross rod 11 adjusts the film application rate through the movement of the leveling mechanism 2, thus ensuring that the positioning component 1 no longer moves after the leveling mechanism 2 stops detecting defects such as bubbles, preventing damage to the anti-adhesive film from wrinkles. A gear and rack mechanism 14 is slidably connected to the cross rod 11 through a groove, so that the rocker arm 12 on one side of the rack can push the rack to make the gear rotate around its own axis. Axial rotation is converted into rotation about a line parallel to the radial direction of the gears through a bevel gear set. The rack drives the rocker arm 12 on the other side to move, which in turn drives the lever 13 to swing. A push plate 15 is welded to the end of the lever 13 away from the rocker arm 12. The push plate 15 positions the pressure roller 3 by pushing the gear and rack mechanism 14. The rotation of the gear is converted into axial rotation of the pressure roller 3 through the bevel gear set, thereby enabling the pressure roller 3 to move when the waterproof membrane deviates, thus achieving the positioning of the pressure roller 3. A clamping block 16 for preventing material deviation is welded to the side of the push plate 15 away from the pressure roller 3. The waterproof membrane is placed in the clamping block 16. The clamping block 16 restricts the movement of the waterproof membrane by limiting the axial degree of freedom of the waterproof membrane towards the clamping block 16.

[0036] The pressure roller 3 is keyed to a shaft cylinder 17, and a slider 171 is slidably connected inside the shaft cylinder 17. A protective rod 18 is slidably connected to the shaft cylinder 17 via a groove. The function of the slider 171 is to correct the position of the pressure roller 3 as the protective rod 18 rotates, thereby correcting any skewing of the pressure roller 3 caused by gravity changes during use due to the anti-adhesive film. The slider 171 is rotatably connected to the shaft cylinder 17 via a connecting rod. Therefore, when the shaft cylinder 17 rotates, the slider 171 moves axially along the shaft cylinder 17. At this time, the protective rod 18 rotates with the shaft cylinder 17, thus pushing the slider 171 to move. The movement of the slider 171 is driven by the connecting rod. The shaft cylinder 17 rotates in the opposite direction, and the rotation of the shaft cylinder 17 realizes the correction of the pressure roller 3. The end of the protective rod 18 away from the shaft cylinder 17 is hinged to the shaft of the bevel gear set, so that the gear rack mechanism 14, driven by the push plate 15, controls the extension of the protective rod 18. The protective rod 18 centers the pressure roller 3 through the movement of the gear rack mechanism 14, so that the pressure roller 3 is automatically positioned when the connection between the pressure roller 3 and the frame fails and the waterproof membrane shifts. The clamping block 16 is equipped with a control element 19, which is a distance sensor. The control element 19 controls the electric push rod fixed on the cross rod 11 to return the waterproof membrane to the correct position.

[0037] When waterproof membrane needs to be applied, the waterproof membrane is first laid flat on both sides of the cross rod 11. The cross rod 11 is driven by the hydraulic rod to move in the axial direction of the waterproof membrane. The normal distance between the cross rod 11 and the waterproof membrane is 1-2mm. When the axial positions of the waterproof membrane and the anti-adhesive membrane are not consistent, the push plate 15 drives the lever 13 to swing, the lever 13 drives the swing rod 12 to swing, and then the sliding of the gear rack mechanism 14 on the cross rod 11 drives the push plate 15 on the other side of the cross rod 11 to move. At this time, the control element is triggered. The control element starts the electric push rod to push the push plate 15 to drive the clamping block 16 to move the waterproof membrane until the waterproof membrane and the anti-adhesive membrane are on the same axis. Since the rack slides on the cross rod, the gear meshing with the rack rotates synchronously, and then drives the shaft cylinder 17 to rotate through the bevel gear set. The rotation of the shaft cylinder 17 drives the protective rod 18 to rotate, thereby realizing the centering of the pressing roller 3. The movement of the cross rod 11 drives the leveling mechanism 2 to move, realizing the synchronous movement of the cross rod 11 and the leveling mechanism 2.

[0038] like Figure 1-7 As shown, the end of the air guide needle 4 near the leveling mechanism 2 is rectangular, which improves the smoothness of the insertion of the air guide needle 4 between the anti-adhesion membrane and the waterproof membrane. The axial section of the air guide needle 4 is conical. The function of the air guide needle 4 is to change the gas flow rate inside the air guide needle 4 with the movement of the rotating disk 24. Since the total amount of gas in the air bubble between the waterproof membrane and the anti-adhesion membrane is constant, and the diameter of the air guide needle 4 changes from large to small, it can be deduced from Bernoulli's principle that the gas flow rate is faster near the air bubble. This shape increases the gas flow rate in the air bubble between the waterproof membrane and the anti-adhesion membrane, thereby accelerating the process. The function of the air guide needle 4 is to change the axial force of the air guide needle 4 on the material as the rotating disk 24 rotates, thereby preventing the rotating disk 24 from detaching from the vertical rod 41. The diameter of the air guide needle 4 changes from small to large so that when the air guide needle 4 is inserted between the waterproof membrane and the anti-sticking membrane as the rotating disk 24 rotates, the axial force is prevented from being too large. If the axial force is too large when the air guide needle 4 contacts the waterproof membrane, it will cause damage to the waterproof membrane and the anti-sticking membrane, and excessive friction will occur between the vertical rod 41 and the push plate 242, resulting in failure of the fit between the vertical rod 41 and the push plate 242.

[0039] like Figure 1-7 As shown, a centering groove 31 is provided on the inner wall of the pressure roller 3. A limiting piece 311 is provided in the centering groove 31 to prevent the pressure roller 3 from deviating. The function of the limiting piece 311 is to control the distance from itself to the protective rod 18 as the leveling mechanism 2 moves, thereby improving the stability of the centering effect of the protective rod 18 on the pressure roller 3. The limiting piece 311 is welded to the inner wall of the centering groove 31. When the protective rod 18 is engaged with the centering groove 31, it prevents the rotation of the protective rod 18 from causing the protective rod 18 to separate from the centering groove 31, thereby realizing the stable control of the position of the pressure roller 3 by the protective rod 18.

[0040] like Figure 1-9As shown, the leveling mechanism 2 includes a horizontal support rod 21, a sliding bar 22, an electric component 23, a rotating disk 24, a pusher 242, a positioning shaft 26, a spiral groove 241, and a leveling plate 27. The horizontal support rod 21 is keyed to the cross rod 11. The cross rod 11 moves synchronously with the horizontal support rod 21, thereby adjusting the film application rate of the pressure roller 3. This prevents the pressure roller 3 from continuing to apply film when the air guide needle 4 moves, which would cause wrinkles or folds in the anti-adhesive film. A limit rod 243 is welded to the side of the horizontal support rod 21 near the cross rod 11. The side of the limit rod 243 near the pressure roller 3 is arc-shaped. The limiting rod 243 positions the pressure roller 3, thereby ensuring that the distance between the pressure roller 3 and the waterproof membrane remains consistent, improving the film application effect. A sliding strip 22 is slidably connected to the horizontal support rod 21 via a groove. The function of the sliding strip 22 is to control the distance between the cross rod 11 and the material via the horizontal support rod 21. The sliding strip 22 controls the hydraulic rod connected to the cross rod 11 via a sensor, thereby controlling the movement of the cross rod 11. A limiting block 222 is provided at the connection between the sliding strip 22 and the horizontal support rod 21 to prevent the sliding strip 22 from moving at the horizontal support rod 21. During the sliding process, the sliding bar detaches from the horizontal support rod 21. A spherical block 221 is hinged to the lower end of the sliding bar 22. The spherical block 221 pushes the gas into the air guide needle 4 by squeezing the air bubble, thereby changing the gas flow rate inside the air guide needle 4 and improving the working effect of the air guide needle 4. At the same time, the rolling phase has a more accurate effect in determining the position of the air bubble than the cylindrical rod. The sliding bar 22 is made of lightweight honeycomb plastic. If the material density is too high, the air bubble will not be able to cause the sliding bar 22 to deflect. An electric component 23 is installed within the stroke of the sliding bar 22. This electric component 23 is an electric... The push rod and sliding bar 22 control the electric component 23 to start or stop by changing their position relative to the material, thereby realizing the movement of the electric component 23 when the sliding bar 22 moves. The moving distance of the electric push rod 23 changes according to the position of the sliding bar 22. When the sliding bar is closer to the air guide needle 4, the electric component 23 moves a shorter distance, thereby controlling the air guide needle 4 to move to a reasonable position. The electric component 23 is fixedly connected to the rotating disk 24, and the electric component 23 is triggered by the sliding bar 22 to push the rotating disk 24 to move.

[0041] A suction tube 25 is keyed to one end of the rotating disk 24 near the air guide tube, and the other end of the suction tube 25 is keyed to the air guide needle 4. The suction tube 25 changes its shape by rotating the rotating disk 24, thereby absorbing the gas in the air guide needle 4. The suction tube 25 is a flexible tube with holes. When the suction tube 25 rotates with the rotating disk 24, it wraps around the rotating disk 24, and the rotating disk 24 squeezes the suction tube 25. The gas in the suction tube 25 is discharged through the holes, thereby improving the air guide needle 4's effect on removing air bubbles. A push plate 242 is arranged circumferentially on the rotating disk 24. The function of the push plate 242 is to control the synchronization between the air guide needle 4 and the rotating disk 24. The length of the push plate 242 is consistent with the distance between two adjacent vertical rods 41. Therefore, when the push plate 242 rotates with the rotating disk 24, it directly drives the vertical rods 41 to move, which in turn drives the air guide needle 4 to move. The rotation of the push plate 242 pushes the vertical rods 41 to move, which in turn drives the air guide needle 4 to change its distance relative to the material. When the rotating disk 24 reverses, the push plate 242 reverses with the air guide needle 4, which in turn drives the vertical rods 41 to reverse, realizing the reciprocating motion of the air guide needle 4. The rotating disk 24 is slidably connected to a positioning shaft 26 via a groove. The positioning shaft 26 is keyed to a horizontal support rod. A spiral groove 241 is provided on the positioning shaft 26. The spiral groove 241 is used for... The rotating disk 24 is controlled by the spiral groove 241, which, through threaded transmission, converts the movement of the rotating disk 24 with the electric component 23 into rotation. When the pitch of the spiral groove 241 is equal to the stroke of the electric component 23, the rotating disk 24 rotates one revolution. Therefore, the spiral groove 241 controls the rotation angle of the rotating disk 24, thus ensuring that when the electric component 23 moves, the rotating disk 24 rotates at a fixed angle, and the rotation angle is linearly positively correlated with the moving distance of the electric component 23. The spiral groove 241 and the rotating disk 24 are in clearance fit, thereby changing the stroke range of the air guide needle 4, and thus enabling the rotating disk 24 to move with the electric component 23 simultaneously. Rotating, a flat plate 27 is welded to the horizontal support rod 21. A scraper 271 is welded to the bottom of the flat plate 27. The scraper 271 squeezes the gas at the opening of the gas guide tube, thereby preventing the gas in the gas guide tube from flowing back. When the gas remaining in the gas guide needle 4 flows back to the bubble through the gas guide needle 4, the scraper 271 presses the bubble tightly, thereby realizing the unidirectional flow of gas in the bubble, preventing the gas from flowing back after being extracted, which would cause the bubble to remain and thus prevent the anti-adhesion membrane from being damaged. The spacing of the scraper 271 is equal to the spacing of the vertical rod 41, thereby realizing that the scraper 271 flattens the gas in the bubble as the gas guide needle 4 moves, further preventing the gas in the gas guide needle 4 from flowing back.

[0042] When the waterproof membrane needs to be applied, the horizontal support rod 21 moves with the cross rod 11, and the sliding rod moves in the axial position of the waterproof membrane. When there are air bubbles between the waterproof membrane and the anti-adhesive film, the sliding strip 22 is lifted, which in turn controls the electric component 23 to move and push the rotating disk 24 to move. The spiral groove 241 on the positioning shaft 26 is fitted with the rotating disk 24 with clearance, so the rotating disk 24 moves while rotating with the positioning shaft 26, which in turn drives the air extraction pipe 25 to rotate. During the rotation of the air extraction pipe 25, the air extraction pipe 25 is gradually squeezed and the gas inside the pipe is discharged. When the air guide needle 4 moves away from the waterproof membrane, the flat plate 27 moves with the cross rod 11, and the scraper 271 on the lower surface of the flat plate 27 moves to level it.
