Technical Field
[0001] This utility model relates to the field of waterproof membrane technology, specifically to a self-adhesive waterproof membrane laying machine. Background Technology
[0002] Self-adhesive waterproof membrane is a high-quality building waterproof material with self-adhesive properties. It is the best waterproof, moisture-proof and sealing material for subways, tunnels and sites where open flames are prohibited. It is also suitable for waterproofing and corrosion protection of pipes. Therefore, its application range is very wide. During the installation of waterproof membrane, a laying machine is required for assistance.
[0003] The existing laying machine fixes the roll of self-adhesive waterproof membrane to a mobile frame, places one side of the self-adhesive waterproof membrane on the ground, and then lays the self-adhesive waterproof membrane by moving the laying machine. However, after the laying is completed, the membrane needs to be re-compacted, which consumes a lot of time for the operators.
[0004] The aforementioned paving machine has difficulty compacting the laid roll material, requiring operators to re-compact it after installation, thus reducing the effectiveness of the device. Utility Model Content

[0007] The connecting plate is installed on the side of the movable frame. A fixing plate is installed on the inner side of the connecting plate. A sensor is installed inside the connecting plate. A controller is installed on the upper surface of the movable frame. The output end of the sensor is electrically connected to the input end of the controller. A push rod motor is installed on the side of the fixing plate away from the movable frame. The output end of the push rod motor passes through the connecting plate. The output end of the controller is electrically connected to the input end of the push rod motor. The movable column is slidably connected inside the connecting plate. The output end of the push rod motor is installed on the side of the movable column. The transmission rod is rotatably connected inside the movable column. A transmission gear is sleeved on the top end of the transmission rod. A rack is installed on the upper surface of the fixing plate. The transmission gear meshes with the rack. The connecting disc is installed at the bottom end of the transmission rod. A fixing frame is installed on the outer surface of the connecting disc. An auxiliary roller is rotatably connected inside the fixing frame.
[0008] In a preferred embodiment of the self-adhesive waterproof membrane laying machine of this utility model, in order to facilitate the disassembly and assembly of the auxiliary plate, an installation plate is slidably connected inside the movable frame, and a connecting block is slidably connected inside the installation plate.
[0009] In a preferred embodiment of the self-adhesive waterproof membrane laying machine of this utility model, in order to prevent the contact roller from being pushed upward by the membrane, an auxiliary plate is installed on the inner side of the connecting block, and a buffer spring is installed inside the auxiliary plate.
[0010] In a preferred embodiment of the self-adhesive waterproof membrane laying machine of this utility model, in order to control the movement height of the membrane, a movable frame is installed at the bottom end of the buffer spring, and the movable frame is slidably connected to the inside of the auxiliary plate.
[0011] As a preferred embodiment of the self-adhesive waterproof membrane laying machine of this utility model, in order to facilitate the replacement of the membrane, a contact roller is rotatably connected inside the movable frame, a connecting rod is inserted inside the auxiliary plate, and an auxiliary disc is installed on the outer surface of the connecting rod.

[0013] The working principle and beneficial effects of this utility model are as follows:
[0014] In this invention, the transmission gear rotates along the rack, causing the transmission rod to drive the connecting disc to rotate. The auxiliary roller then lays the pre-laid roll material. Compared to existing technologies where operators need to re-compact the material after laying, this device can compact the roll material during the laying process, reducing the number of steps required for operators to lay the roll material.
[0015] In this invention, the movable frame is held in place by a buffer spring, causing the contact roller to press the roll material downwards. Compared with the direct laying of roll material in the prior art, this device can compact the roll material during the laying process, reducing the number of times operators need to re-compact the roll material after laying it, and improving the effectiveness of the device.
