Description

Technical Field

[0001] This invention relates to the field of architectural membrane material preparation, and more specifically to a method for preparing architectural membrane materials. Background Technology

[0002] Composite geomembrane is a type of building membrane material. It is a waterproof material made by combining geotextile and geomembrane. It is mainly used for seepage prevention. Composite geomembrane is divided into one geotextile and one geomembrane and two geotextiles and one geomembrane, which can meet the needs of civil engineering projects such as water conservancy, municipal engineering, construction, transportation, subway, and tunnel.

[0003] In existing geomembrane systems, the membrane material is wound around the outside of the winding roller and placed on the surface of two rotating rollers for winding. The membrane material removed from the pressing roller is directly wound up. The tension of the membrane material during winding is insufficient, which can easily lead to loosening of the membrane material during winding. After winding, the membrane material needs to be lifted out from between the two rollers manually or by moving a lifting device, and then packaged. The operation is relatively cumbersome and it is not convenient to automatically remove the wound membrane material or automatically package the membrane material during unloading. Summary of the Invention

[0004] To overcome the aforementioned technical problems, the present invention aims to provide a method for preparing architectural membrane materials. This method involves passing a cooled geomembrane under two tension rollers and over a top rod. The top rod pushes the geomembrane upwards and bends it, adjusting the tension before winding. This tension is achieved by tightening the geomembrane before winding, thus regulating its tension during winding to prevent insufficient tension from causing looseness during winding and improving the neatness of the winding. After the support rollers move a certain distance, the geomembrane is cut, and the support rollers continue to move. The second sliding sleeve moves the geomembrane along the feeding guide rail, allowing the geomembrane to be automatically fed. This replaces manual labor or a moving hoist in lifting the membrane material from between the rotating roller and the support roller after winding, simplifying the feeding process and facilitating the automatic removal of the wound membrane material. One end of the packaging film is clamped between the pressure rod and the clamping plate and fixed by the second bolt. When the geomembrane moves to the packaging film, the packaging film wraps around it. Then, the second electric push rod extends, pushing the hot knife downward to heat seal the packaging film and package the geomembrane. This facilitates automatic packaging of the membrane material during feeding.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A method for preparing architectural membrane materials includes processing steps of material preparation, composite preparation, and molding, as follows:

[0007] (1) Material preparation: Prepare two raw materials: high-density polyethylene film and non-woven fabric. Conduct quality inspection on the two raw materials. After they pass the inspection, proceed to the next step of the preparation process.

[0008] (2) Composite preparation: High-density polyethylene film and non-woven fabric are treated by coating and hot-melt technology respectively.

[0012] Furthermore, the T-shaped bracket has a slider slidably connected inside, a top rod is rotatably connected between the two sliders, and a screw is screwed onto the upper end of the T-shaped bracket, the screw passing through the T-shaped bracket and rotatably connected to the slider.

[0013] Furthermore, the upper surface of the first slide rail is provided with a through groove, and fixed sleeves are symmetrically fixedly installed on the upper surface of the first slide rail. A lead screw is rotatably connected inside the two fixed sleeves. A motor is fixedly installed on the upper surface of the first slide rail. The output end of the motor is fixedly connected to the lead screw. A threaded sleeve is screwed onto the outside of the lead screw. The threaded sleeve passes through the through groove and is fixedly connected to the first slide sleeve.

[0014] Furthermore, the following features are provided: symmetrically fixedly mounted on both sides of the main body of the winding device are fixed frames, and a No. 2 lead screw is rotatably connected inside the fixed frame; a No. 2 motor is fixedly mounted on both sides of the main body of the winding device; the output end of the No. 2 motor is fixedly connected to one end of the No. 2 lead screw; a mounting frame is screwed onto the outside of the No. 2 lead screw; a tensioning wheel is symmetrically rotatably connected inside the mounting frame; and a No. 5 motor is fixedly mounted on one side of the main body of the winding device, and the output end of the No. 5 motor is fixedly connected to a pulley.

[0015] Furthermore, a bolt is movably embedded in the outer surface of the connecting sleeve. The bolt passes through two adjacent connecting rods and the connecting sleeve and is screwed into the connecting rod. A clamping rod is movably connected between the two symmetrical connecting sleeves.

[0016] Furthermore, a connecting cover is movably sleeved at one end of the feeding guide rail, and a first electric push rod is fixedly installed on one side surface of the feeding guide rail. A third motor is fixedly installed at one end of the first electric push rod via a bracket, and a connecting block is fixedly installed at the output end of the third motor. The connecting block is movably engaged with the second sliding sleeve.

[0017] Furthermore, a spring is fixedly installed on one end surface of the second slide rail, and one end of the spring is fixedly connected to the support frame. A fourth motor is fixedly installed on one side surface of the support frame through a bracket, and the output end of the fourth motor is fixedly connected to the adjacent hollow rotating rod.

[0018] Furthermore, clamping plates are fixedly installed on the lower surfaces of the two feeding guide rails, and pressure rods are movably provided on one side of the clamping plates. No. 2 bolts are movably embedded at both ends of one side surface of the pressure rods. The No. 2 bolts pass through the pressure rods and clamping plates, and are screwed into the clamping plates.

[0019] The beneficial effects of this invention are:

[0020] 1. By passing the cooled geomembrane under the two tension rollers and over the top rod, turning the screw drives the slider upward, causing the top rod to push the geomembrane upward and bend it, thus adjusting the tension of the geomembrane before winding. This tightens the geomembrane before winding, adjusting its tension during winding to prevent insufficient tension from causing the membrane to sag during winding and improving the neatness of the membrane winding.

[0021] 2. Turn on motor number one, causing the threaded sleeve to move the support roller along slide rail number one. Adjust the position of the support roller according to the different diameters of the geomembrane after winding, and keep the winding point on the geomembrane in the same position to maintain the tension of the geomembrane during winding. Extend electric push rod number one, so that the connecting block is inserted into one end of slide sleeve number two. Turn on motor number three, driving slide sleeve number two to rotate, providing power for the initial winding of geomembrane. When the geomembrane is wound to fit against the surface of the rotating roller and the support roller, control motor number three to move out, and turn on motor number five to make the rotating roller and the support roller rotate synchronously, rotating and winding the geomembrane between them.

[0022] 3. After the support roller moves a certain distance, the geomembrane is cut. The support roller continues to move, causing the No. 2 sliding sleeve to move the geomembrane along the feeding guide rail, so that the geomembrane is automatically fed. This replaces manual labor or moving the lifting device to lift the film material out from between the rotating roller and the support roller after winding, simplifying the feeding process and facilitating the automatic removal of the wound film material. The No. 4 motor runs, driving the hollow rotating rod to rotate and unfold and move the packaging film downward. One end of the packaging film is clamped between the pressure rod and the clamping plate and fixed by the No. 2 bolt. When the geomembrane moves to the packaging film, the packaging film wraps around it. Then the No. 2 electric push rod extends and pushes the hot knife downward to heat seal the packaging film and package the geomembrane, thus facilitating the automatic packaging of the film material during feeding.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figure 1-9 As shown, a method for preparing architectural membrane materials includes processing steps of material preparation, composite preparation, and molding. The specific steps are as follows:

[0036] (1) Material preparation: Prepare two raw materials: high-density polyethylene film and non-woven fabric. Conduct quality inspection on the two raw materials. After they pass the inspection, proceed to the next step of the preparation process.

[0037] (2) Composite preparation: High-density polyethylene film and non-woven fabric are treated by coating and hot-melt technology respectively. Coating is to uniformly coat the surface of high-density polyethylene film with an adhesive to increase the adhesion to non-woven fabric. Hot-melt is to heat and melt the two materials at high temperature to make them tightly bonded together.

[0038] (3) Processing and shaping: The composite material is fed into the preparation device and processed into a composite geomembrane or sheet through extrusion, stretching and cooling. Then it is rolled into a roll by a winding device.

[0039] In step (3), after the geomembrane cools down, the geomembrane is tensioned using a tensioning assembly, and then automatically unloaded and packaged after being rolled up.

[0040] Specifically, the preparation device includes a winding device body 1. T-shaped brackets 101 are symmetrically fixedly mounted on the upper end of the winding device body 1. Tension rollers 102 are symmetrically rotatably connected between the two T-shaped brackets 101. A first slide rail 2 is symmetrically fixedly mounted on the upper end of the winding device body 1. A first sliding sleeve 201 is rotatably connected inside the first slide rail 2. A support roller 202 is rotatably connected between the two first sliding sleeves 201. A rotating roller 207 is rotatably connected inside the winding device body 1. Pulleys 3 are fixedly mounted on the surfaces of both ends of the support roller 202 and the rotating roller 207. A belt 301 is movably sleeved on the outer side of the two pulleys 3 located at the same end. The main body 1 has a feeding guide rail 4 fixedly installed on both sides of the interior surface. The feeding guide rail 4 is rotatably connected to a second sliding sleeve 401. The second sliding sleeve 401 is fixedly installed with a sliding rod 402. The sliding rod 402 is symmetrically slidably connected to a connecting rod 403 on the outside. The connecting rod 403 is slidably connected to a connecting sleeve 404 on the outside. The feeding guide rail 4 has a second sliding rail 5 fixedly installed on the outer surface. The second sliding rail 5 is slidably connected to a support frame 501. The support frame 501 is rotatably connected to a hollow rotating rod 503. The feeding guide rail 4 has a second electric push rod 505 fixedly installed on one side surface. The two second electric push rods 505 are fixedly installed with a hot knife 506.

[0041] In this embodiment, a slider 103 is slidably connected inside the T-shaped bracket 101, and a top rod 104 is rotatably connected between the two sliders 103. A screw 105 is screwed onto the upper end of the T-shaped bracket 101. The screw 105 passes through the T-shaped bracket 101 and is rotatably connected to the sliders 103. The composite geomembrane is passed under the two tension rollers 102 and over the top rod 104. Tightening the screw 105 moves the sliders 103 upward, causing the top rod 104 to push the geomembrane upward and bend it, adjusting the tension of the geomembrane before winding. Before winding, the geomembrane is stretched and its tension is adjusted to prevent insufficient tension from causing the membrane to sag during winding, thus improving the neatness of the membrane winding. A through groove is provided on the upper surface of slide rail 2. Fixing sleeves 203 are symmetrically fixedly installed on the upper surface of slide rail 2. A lead screw 204 is rotatably connected inside the two fixing sleeves 203. A motor 205 is fixedly installed on the upper surface of slide rail 2. The output end of the motor 205 is fixedly connected to the lead screw 204. A threaded sleeve 206 is screwed onto the outside of the lead screw 204. The threaded sleeve 206 is fixedly connected to the first sliding sleeve 201 through the through groove. The first motor 205 operates, driving the first lead screw 204 to rotate, causing the threaded sleeve 206 to drive the support roller 202 to move along the first slide rail 2. This allows the support roller 202 to adjust its position according to the different diameters of the geomembrane after winding, keeping the winding point above the geomembrane in a uniform position and maintaining the tension of the geomembrane during winding. Fixed frames 304 are symmetrically fixedly installed on both sides of the main body 1 of the winding device. The second lead screw 305 is rotatably connected inside the fixed frame 304. 1. A second motor 306 is fixedly installed on both sides of the surface. The output end of the second motor 306 is fixedly connected to one end of the second lead screw 305. A mounting bracket 302 is screwed to the outside of the second lead screw 305. A tension wheel 303 is symmetrically rotated inside the mounting bracket 302. When the second motor 306 runs, it drives the second lead screw 305 to rotate and adjust the height of the mounting bracket 302. When the belt 301 changes angle with the movement of the pulley 3, the tension wheel 303 always abuts against the belt 301 to maintain the tension of the belt 301 and facilitate transmission.

[0042] Specifically, a No. 5 motor is fixedly installed on one side of the main body 1 of the winding device. The output end of the No. 5 motor is fixedly connected to a pulley 3. When the No. 5 motor operates, the rotating roller 207 and the support roller 202 rotate synchronously through the transmission of the belt 3 and the pulley 301, thereby rotating and winding the geomembrane between them. A No. 1 bolt 406 is movably embedded in the outer surface of the connecting sleeve 404. The No. 1 bolt 406 passes through two adjacent connecting rods 403 and the connecting sleeve 404, and is screwed into the connecting rods 403. A clamping rod 405 is movably connected between the two symmetrical connecting sleeves 404, clamping one end of the geomembrane between the two clamping rods 405. Tightening the No. 1 bolt 406 causes the two connecting sleeves 404 to move the clamping rods 405 towards each other. One end of the geomembrane is fixed; a connecting cover 407 is movably sleeved on one end of the feeding guide rail 4, and a first electric push rod 408 is fixedly installed on one side surface of the feeding guide rail 4. A third motor 409 is fixedly installed on one end of the first electric push rod 408 through a bracket. A connecting block is fixedly installed on the output end of the third motor 409. The connecting block is movably engaged with the second sliding sleeve 401. When the first electric push rod 408 extends, the connecting block is inserted into one end of the second sliding sleeve 401. The third motor 409 runs, driving the second sliding sleeve 401 to rotate, providing power for the initial winding of the geomembrane. When the geomembrane is wound up to be able to adhere to the surfaces of the rotating roller 207 and the support roller 202, the third motor 409 is controlled to move out, so that the rotating roller 207 and the support roller 202 drive the geomembrane to wind up.

[0043] In this embodiment, a spring 502 is fixedly installed on one end surface of the second slide rail 5. One end of the spring 502 is fixedly connected to the support frame 501. A fourth motor 504 is fixedly installed on one side surface of the support frame 501 via a bracket. The output end of the fourth motor 504 is fixedly connected to the adjacent hollow rotating rod 503. When the packaging film winding roller is inserted between the two hollow rotating rods 503, the fourth motor 504 operates, driving the hollow rotating rods 503 to rotate and unfold and move the packaging film downward. A clamping plate 507 is fixedly installed on the lower surface of the two feeding guide rails 4. A pressure rod 508 is movably provided on one side of the clamping plate 507. A second bolt 509 is movably embedded at both ends of one side surface of the pressure rod 508. The second bolt 509 passes through the pressure rod 508 and the clamping plate 507, and the second bolt 509 is screwed into the clamping plate 507. One end of the packaging film is clamped between the pressure rod 508 and the clamping plate 507, and is moved by the second bolt 509. When the geomembrane is moved to the packaging film, the packaging film wraps around it. Then, the second electric push rod 505 extends, pushing the hot knife 506 downward to heat-seal the packaging film and package the geomembrane. This facilitates automatic packaging of the film material during unloading. The upper surface of the main body 1 of the winding device is symmetrically fixed with a third electric push rod 6. One end of each third electric push rod 6 is rotatably connected to a limit rod 601, which controls the extension of the third electric push rod 6 so that the limit rod 601 always presses against the geomembrane to prevent it from falling. After the support roller 202 moves a certain distance, the geomembrane is cut. The support roller 202 continues to move, causing the second sliding sleeve 401 to drive the geomembrane along the unloading guide rail 4, so that the geomembrane is automatically unloaded. This replaces manual labor or moving the lifting device to lift the film material out from between the rotating roller 207 and the support roller 202 after winding, simplifying the unloading process and facilitating the automatic removal of the wound film material.

[0044] Working principle: In use, the cooled geomembrane is passed under the two tension rollers 102 and over the top rod 104. Tightening the screw 105 moves the slider 103 upward, causing the top rod 104 to push the geomembrane upward and bend it, adjusting the tension of the geomembrane before winding. This tensioning of the geomembrane before winding prevents insufficient tension from causing it to sag during winding, improving the neatness of the winding. One end of the geomembrane is clamped between the two clamping rods 405. Tightening the first bolt 406 causes the two connecting sleeves 404 to move the clamping rods 405 towards each other, fixing one end of the geomembrane. The first motor 20... 5. The operation drives the first lead screw 204 to rotate, causing the threaded sleeve 206 to move the support roller 202 along the first slide rail 2. This allows the support roller 202 to adjust its position according to the different diameters of the geomembrane after winding, ensuring that the winding point above the geomembrane is in the same position, maintaining the tension of the geomembrane during winding. The second motor 306 operates, driving the second lead screw 305 to rotate, adjusting the height of the mounting frame 302. As the belt 301 changes angle with the movement of the pulley 3, the tensioning wheel 303 always abuts against the belt 301, maintaining the tension of the belt 301 for easy transmission. The first electric push rod 408 extends, allowing the connecting block to be inserted into one end of the second slide sleeve 401. Motor 409 operates, driving the second sliding sleeve 401 to rotate, providing power for the initial winding of the geomembrane. When the geomembrane is wound up to fit against the surfaces of the rotating roller 207 and the support roller 202, motor 409 is moved out, and motor 5 operates. Through the transmission of belt 3 and pulley 301, the rotating roller 207 and the support roller 202 rotate synchronously, rotating and winding the geomembrane between them. The third electric push rod 6 is extended, ensuring that the limit rod 601 always abuts against the geomembrane to prevent it from falling. After the support roller 202 moves a certain distance, the geomembrane is cut. The support roller 202 continues to move, causing the second sliding sleeve 401 to drive the geomembrane along the feeding guide rail. 4. The movement allows for automatic feeding of the geomembrane, and after winding, it replaces manual labor or a moving hoist to lift the membrane material from between the rotating roller 207 and the support roller 202, simplifying the feeding process and facilitating the automatic removal of the wound membrane material. The fourth motor 504 operates, driving the hollow rotating rod 503 to rotate, unfolding and moving the packaging film downwards. One end of the packaging film is clamped between the pressure rod 508 and the clamping plate 507, and fixed by the second bolt 509. When the geomembrane moves to the packaging film, the packaging film wraps around it. Then, the second electric push rod 505 extends, pushing the hot knife 506 downwards to heat-seal the packaging film, thus packaging the geomembrane and facilitating automatic packaging of the membrane material during feeding.
