Description
Technical Field
[0001] The utility model relates to the field of grinding devices for waterproof coiled materials, in particular to a grinding device for removing a non-bearing layer of a waterproof coiled material. Background Art
[0002] The grinding device for removing the non-bearing layer of waterproof membrane is a special equipment that uses the grinding principle to mechanically remove the non-bearing layer on the surface of waterproof membrane. The device can quickly and efficiently remove the non-bearing layer on the surface of waterproof membrane, making the surface of the membrane more flat and smooth.
[0003] However, traditional grinding devices mostly rely on manual operation, and the grinding efficiency is low. In order to improve efficiency, some production plants or laboratories have introduced simple grinding equipment, but these devices are unable to cope with waterproof membranes of different thicknesses and specifications and lack sufficient adaptability. In addition, traditional grinding devices often generate a large amount of dust and impurities during the grinding process. These dusts not only pollute the surface of the membrane, but may also pose a serious threat to the working environment and the health of the operators. After the grinding is completed, the testers need to cut the waterproof membrane to obtain samples of specifications that meet the test requirements. Traditional cutting devices often use simple mechanical cutting methods, which are difficult to adapt to membranes of different sizes and specifications, reducing the work efficiency of the experimenters.

[0029] The cutting assembly 6 includes a pair of telescopic cylinders 61 symmetrically arranged at the bottom of the mounting frame 3. The telescopic cylinders 61 are used to adjust the height and position of the cutting assembly 6 to adapt to coils of different sizes.

In the processing process after grinding is completed, the waterproof coiled material needs to be packaged in barrels. Therefore, when cutting the waterproof coiled material, the sharpness and wear resistance of the circular cutter 610 ensure that it can cut the coiled material efficiently without causing excessive damage to the coiled material.
[0031] When in use, the staff must first check whether all parts of the grinding device are in good working condition. After the inspection, the staff can connect the grinding device to the power supply to power on the entire equipment. The staff will start the telescopic rod extension of telescopic cylinder 1 41 and telescopic cylinder 2 61 in turn to make the grinding assembly 4 and cutting assembly 6 descend to the preset height according to the waterproof membrane to be ground.
[0032] The staff can start the conveyor belt 1 to smoothly convey the waterproof coiled material to the grinding assembly 4. When the waterproof coiled material arrives at the grinding assembly 4, the motor 1 43 is started to drive the pulley 1 44 to rotate. The pulley 1 44 drives the pulley 2 47 to rotate through the transmission belt 1 48, thereby realizing the rotation of the grinding roller 1 46. At the same time, the pulley 3 49 at one end of the grinding roller 1 46 drives the pulley 4 412 to rotate through the transmission belt 2 413, thereby realizing the rotation of the grinding roller 2 411. The abrasive layers on the surfaces of the two grinding rollers work together to remove the surface of the coiled material. Non-bearing layer, during the grinding process, the cylindrical brush 53 rotates through the rotating shaft 1 52, so that the dust and impurities generated during the grinding process are separated from the surface of the waterproof membrane. The softness and wear resistance of the cylindrical brush 53 ensure that it can efficiently remove dust without causing damage to the surface of the membrane. At the same time, start the motor 2 58, drive the fan 510 to rotate, generate airflow to blow the dust away from the surface of the membrane, and fall into the waste collection box 2 below. The dust cover 511 on the side of the fan 510 mounting shell 57 can protect the fan 510 from dust erosion.
[0033] During the processing after grinding, the waterproof membrane usually needs to be cut into samples that meet the test requirements. Therefore, the waterproof membrane needs to be cut. The staff can start the motor 3 65 to drive the screw 63 to rotate. The thread on the outside of the screw 63 is connected to the drive block 66. The drive block 66 moves along the screw 63, thereby driving the circular cutter 610 to move. The sharpness and wear resistance of the circular cutter 610 ensure that it can cut the membrane efficiently.
