Description

Technical Field

[0002] In building waterproofing construction, waterproof membranes are widely used in roofing and other waterproofing applications due to their excellent waterproofing performance and ease of installation. Currently, the laying and cutting of waterproof membranes mainly rely on manual operation: workers typically use hand rollers to press the membrane firmly onto the roof surface, and after laying the membrane in one area, they must manually cut it with scissors, utility knives, or other hand tools before moving on to the next area. However, this existing manual method of laying, pressing, and cutting waterproof membranes is inefficient, increases labor intensity, and makes it difficult to ensure the flatness of the membrane and the neatness of the cut edges.

[0003] Therefore, we propose a cutting device for waterproof membrane construction to solve the above problems. Utility Model Content

[0023] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0024] See Figures 1-5This application provides a cutting device for waterproof membrane construction, including a laying frame 1 and a laying mechanism 10 and a cutting mechanism 12 mounted on the laying frame 1. A rectangular clearance hole 2 is provided at the top of the laying frame 1. A vertical plate 3 is fixedly installed on the rear side of the top of the laying frame 1. A rotating shaft 4 is rotatably mounted on the front side of the vertical plate 3, and waterproof membrane 5 is wound on the rotating shaft 4. A motor 6 is fixedly installed on the rear side of the vertical plate 3, and the output shaft end of the motor 6 is fixedly connected to the rear end of the rotating shaft 4. Four support legs 7 are fixedly installed at the bottom of the laying frame 1, symmetrically distributed in pairs. The bottom ends of the four support legs 7... All are equipped with casters 8, and the two rear support legs 7 are fixedly mounted on the same T-shaped crossbeam 9. The laying mechanism 10 is located at the bottom of the T-shaped crossbeam 9. The laying mechanism 10 is used to lay the waterproof membrane 5 on the roof. The laying mechanism 10 includes a second hydraulic cylinder 101, a horizontal plate 102, a U-shaped left-sloping mounting bracket 103, a first pressure roller 104, a U-shaped vertical mounting bracket 105, a second pressure roller 106, a U-shaped right-sloping mounting bracket 107, and a third pressure roller 108. The second hydraulic cylinder 101 is fixedly installed at the bottom of the T-shaped crossbeam 9, and the horizontal plate 102 is fixedly installed on the hydraulic cylinder. At the output shaft end of the second 101, the U-shaped left-sloping mounting bracket 103, the U-shaped vertical mounting bracket 105, and the U-shaped right-sloping mounting bracket 107 are all fixedly installed at the bottom of the horizontal plate 102 and distributed sequentially from left to right. The first pressure roller 104 is rotatably installed at the bottom of the U-shaped left-sloping mounting bracket 103, the second pressure roller 106 is rotatably installed at the bottom of the U-shaped vertical mounting bracket 105, and the third pressure roller 108 is rotatably installed at the bottom of the U-shaped right-sloping mounting bracket 107. The rotating shaft 4 is driven to rotate by the first motor 6, which can realize the automatic unwinding of the waterproof membrane 5. This works in conjunction with the first pressure roller 104 in the laying mechanism 10. The synergistic effect of pressure roller 2 106 and pressure roller 3 108 enables the waterproof membrane 5 to be laid quickly and smoothly on the roof, effectively reducing the tediousness of manual laying of the waterproof membrane 5 and significantly improving construction efficiency. It should be noted that the left-slanted pressure roller 1 104 can pre-press and level the waterproof membrane 5, the vertically set pressure roller 2 106 can further compact the waterproof membrane 5, and the right-slanted pressure roller 3 108 can further eliminate the wrinkles of the waterproof membrane 5 during the process of compacting the waterproof membrane 5 again, thereby ensuring the flatness of the waterproof membrane 5.

[0025] In this embodiment, the bottom edges of pressure roller 104, pressure roller 206, and pressure roller 308 are flush, and the outer surfaces of pressure roller 104, pressure roller 206, and pressure roller 308 are all smooth. This ensures that pressure roller 104, pressure roller 206, and pressure roller 308 can smoothly apply downward pressure to the waterproof membrane 5 laid on the roof, ensuring that the waterproof membrane 5 fits the roof surface better and enhancing the laying quality.

[0026] In this embodiment, an inclined support frame 11 is fixedly installed on the bottom left side of the laying frame 1. A cutting mechanism 12 is located at the bottom of the support frame 11. The cutting mechanism 12 is used to cut the waterproof membrane 5. The cutting mechanism 12 includes an L-shaped plate 121, a hydraulic cylinder 122, a mounting beam 123, a rectangular slide 126, an electric heating plate 127, and a cutter 128. The L-shaped plate 121 is fixedly installed at the bottom of the support frame 11, the hydraulic cylinder 122 is fixedly installed on the inner wall of one side of the L-shaped plate 121, and the mounting beam 123 is fixedly installed on the inner wall of the L-shaped plate 121. A rectangular slide groove 124 is provided on the right side of the mounting beam 123, which is installed at the output shaft end of the hydraulic cylinder 122. A rectangular slide block 126 is slidably installed in the rectangular slide groove 124, with the right side of the rectangular slide block 126 extending outside the rectangular slide groove 124. An electric heating plate 127 is fixedly installed on the right side of the rectangular slide block 126, and a cutter 128 is detachably installed and fixed on the right side of the electric heating plate 127. The cutting mechanism 12 also includes a lead screw 125 and a motor 129. The lead screw 125 is rotatably installed in the rectangular slide groove 124. The seat 126 is threaded onto the lead screw 125. The second motor 129 is fixedly mounted on the front outer wall of the mounting beam 123. The output shaft end of the second motor 129 is fixedly connected to the front end of the lead screw 125. The first hydraulic cylinder 122 is used to adjust the horizontal position of the cutter 128. By using the second motor 129 to drive the lead screw 125 to rotate, the rectangular slide 126 can be controlled to slide linearly within the rectangular slide groove 124, thereby realizing the horizontal movement of the electric heating plate 127 and the cutter 128. The cutter 128 can be used to cut the waterproof membrane. 5. Automatic cutting can effectively replace the existing manual cutting method using cutting tools, reducing the labor intensity of workers. The heat generated by the electric heating plate 127 can be transferred to the cutter 128, making the cutting of waterproof membrane more stable and smooth, and ensuring that the cut is neat. It should be noted that the motor 129 is a reversible motor. The heating temperature of the electric heating plate 127 is selected according to the material of the waterproof membrane 5, ensuring that the heating temperature of the cutter 128 reaches the melting point of the waterproof membrane 5.

[0027] In this embodiment, a horizontal guide plate 1210 located above the hydraulic cylinder 122 is fixedly installed on the inner wall of one side of the L-shaped plate 121. The mounting beam 123 is slidably sleeved on the horizontal guide plate 1210. The design of the horizontal guide plate 1210 can not only increase the stability of the position of the mounting beam 123, but also guide the movement direction of the mounting beam 123, ensuring that the mounting beam 123 can move smoothly in a horizontal straight line.

[0028] In this embodiment, the cutter 128 is flush with the horizontal axis of the pressure roller 104, which ensures a smooth and effective cutting process for the waterproof membrane 5.

[0029] In this embodiment, a fixed baffle 13 is fixedly sleeved on the rotating shaft 4, and the rear side of the waterproof membrane 5 abuts against the fixed baffle 13. A movable baffle 14 is movably sleeved on the rotating shaft 4, and the front side of the waterproof membrane 5 abuts against the movable baffle 14. An external thread is provided on the circumferential side of the front end of the rotating shaft 4, and a locking nut 15 is threaded onto the front end of the rotating shaft 4 through the external thread. The locking nut 15 abuts against the front side wall of the movable baffle 14. Through the coordinated action of the fixed baffle 13, the movable baffle 14, and the locking nut 15, it is convenient to install and remove the waterproof membrane 5.

[0030] In this embodiment, a handrail 16 is fixedly installed on the right side of the laying frame 1, and a power supply box 17 is fixedly installed on the top of the laying frame 1. A battery pack 18 is fixedly installed inside the power supply box 17. A controller is fixedly installed on the outer wall of the power supply box 17. The controller is equipped with multiple switches and buttons. Motor 6, Motor 129, Hydraulic cylinder 122, Hydraulic cylinder 101, Electric heating plate 127, controller and battery pack 18 are electrically connected. The multiple switches and buttons are used to control the power supply and operation of motor 6, motor 129, hydraulic cylinder 122, hydraulic cylinder 101 and electric heating plate 127 respectively. The wiring connection method and control method are mature technologies in this field and have been fully disclosed. Therefore, they will not be described in detail here.

[0031] With the above structure, when using the waterproof membrane cutting device provided in this application, the device is pushed to the roof construction site as a whole, the commercially purchased roll of waterproof membrane 5 is mounted on the rotating shaft 4 and abuts against the fixed baffle 13, the movable baffle 14 is mounted on the rotating shaft 4 and abuts against the waterproof membrane 5, and the locking nut 15 is tightened on the front end of the rotating shaft 4 and abuts against the movable baffle 14, thus completing the rapid installation and fixing of the waterproof membrane 5.

[0032] After the waterproof membrane 5 is installed and secured, control motor 6 to run. Motor 6 drives the rotating shaft 4 and the waterproof membrane 5 to rotate synchronously, gradually releasing the waterproof membrane 5. The worker pulls one end of the waterproof membrane 5 to fit against the roof surface, and then controls hydraulic cylinder 101 to extend, causing pressure rollers 104, 106, and 108 to descend vertically until pressure roller 104 applies force to press down on the waterproof membrane 5, stopping hydraulic cylinder 101. Then, the worker pushes the entire device forward slowly and evenly (during this forward movement, another worker needs to hold a flame). The spray gun heats the lower surface of the waterproof membrane 5, which is common knowledge in the field and will not be described in detail here. As the waterproof membrane 5 is continuously released, the pressure roller 104 will initially press the waterproof membrane 5 tightly against the roof surface, the pressure roller 2 106 will press the waterproof membrane 5 tightly against the roof surface a second time, and the pressure roller 3 108 will press the waterproof membrane 5 tightly against the roof surface a third time. Through the three pressing and bonding of the waterproof membrane 5, it can be ensured that the waterproof membrane 5 fits the roof surface better, ensuring that the waterproof membrane 5 is laid flat and enhancing the laying quality.

[0033] After the waterproof membrane is laid in this area, stop motor 6 and turn on electric heating plate 127 to generate heat to heat cutter 128. Then, control hydraulic cylinder 122 to extend until cutter 128 moves linearly, piercing waterproof membrane 5 and contacting the surface of pressure roller 104. Next, control motor 129 to rotate forward or reverse. The output shaft of motor 129 drives screw 125 to rotate, causing rectangular slide 126 to drive electric heating plate 127 and cutter 128 to move linearly horizontally, thereby utilizing... The heated cutter 128 can automatically cut the waterproof membrane 5, effectively replacing the existing manual cutting method using cutting tools, reducing the labor intensity of workers and improving work efficiency. After the waterproof membrane 5 is cut, the motor 129 and the electric heating plate 127 are stopped, and the hydraulic cylinder 122 is controlled to retract and reset, so that the cutter 128 returns to its original position away from the pressure roller 104. Following the above operation steps, the next area can continue to be laid and automatically cut the waterproof membrane 5.
