Description

Technical Field

[0001] This utility model relates to the technical field of waterproof membrane laying equipment, specifically a device for laying roof waterproof membrane. Background Technology

[0002] Waterproof membrane laying equipment is an important tool for improving the efficiency and quality of waterproofing projects. Its main function is to lay waterproof membranes on building surfaces or other base surfaces that require waterproofing treatment, thereby improving the waterproofing performance of the building's roof.

[0003] For example, the utility model patent disclosed in publication number CN216516549U discloses a roof waterproof membrane laying device. To solve the problem of wrinkles and hollows caused by small stones entering the waterproof membrane and roof laying surface, the following technology is adopted: one end of the connecting pipe is provided with a first I-beam, and the first I-beam is wrapped with a first adhesive paper. The other end of the connecting pipe is provided with a second I-beam. The first I-beam and the first adhesive paper are rotated by a stepper motor. The first I-beam and the first adhesive paper clean the small stones on the pre-laid roof surface. The beneficial effect is that the stepper motor drives the connecting rod and bearing to rotate, and the I-beam and the connecting pipe rotate in a fan shape. Since the first adhesive paper is wrapped inside the first I-beam, the first adhesive paper adheres to the small stones on the roof surface during contact with the roof surface. The larger stones are carried out of the pre-laid roof surface of the waterproof membrane by the fan-shaped rotation of the I-beam, which pre-cleans the area before vacuuming and improves the cleaning efficiency.

[0004] Although the above-mentioned laying device can perform the laying operation on the roof, its efficiency in changing the roll material is insufficient, and the material load of the above-mentioned equipment is also insufficient, which reduces the efficiency of roof laying. Therefore, there is an urgent need for a roof waterproof roll laying device to solve the above-mentioned problems. Utility Model Content

[0011] Preferably, the side of the connecting roller does not contact the support bracket to prevent the subsequent unwinding of the waterproof membrane from being restricted.

[0012] Preferably, the limiting turntable engages with the grooved wheel through the limiting groove, and the limiting turntable can lock the grooved wheel through the limiting groove, which can effectively improve the stability of the subsequent unwinding roller unwinding the waterproof membrane.

[0013] Preferably, the diameter of the connecting lever is equal to the width of the fixed slide groove, and the connecting lever drives the grooved wheel to rotate through the fixed slide groove. The servo motor drives the limit turntable and the connecting lever to rotate one revolution, which can drive the grooved wheel to rotate 90 degrees through the connecting lever, which facilitates the subsequent cyclic feeding of the four sets of unwinding rollers, improves the feeding efficiency and the durability of the equipment.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model sets up four sets of unwinding rollers. When the waterproof membrane on one set of unwinding rollers inside the connecting roller is unwound, the servo motor can drive the groove wheel and the connecting roller to rotate 90 degrees through the limiting turntable and the limiting groove and the sliding of the connecting lever and the fixed slide groove. This facilitates the stable and continuous feeding of the next set of membrane, effectively improving the continuity and efficiency of subsequent waterproof membrane laying.

[0024] Transmission device 3 is fixedly installed on the side of the limiting plate 4, directly opposite the material guiding device 2.

[0025] The material guiding device 2 includes a connecting roller 21, four sets of unwinding rollers 22 are detachably snapped onto the inner end face of the connecting roller 21 at equal intervals, and a grooved wheel 23 is fixedly installed at the center of the side end face of the connecting roller 21. Four sets of fixed sliding grooves 24 are equidistantly opened on the inner end face of the grooved wheel 23, and a limiting groove 25 is opened between two adjacent sets of fixed sliding grooves 24.

[0026] The transmission device 3 includes a motor holder 32, a servo motor 31 for transmission is provided on the upper end surface of the motor holder 32, and a limit turntable 33 is fixedly provided at the output end of the servo motor 31. A connecting lever 34 is provided in the middle of the inner end surface of the limit turntable 33.

[0027] The side of the connecting roller 21 does not contact the support bracket 5 to prevent the subsequent unwinding of the waterproof membrane from being restricted.

[0028] The limiting turntable 33 rotates and engages with the grooved wheel 23 through the limiting turntable 25. The limiting turntable 33 can lock the grooved wheel 23 through the limiting turntable 25, which can effectively improve the stability of the subsequent unwinding roller 22 unwinding the waterproof membrane.

[0029] The diameter of the connecting lever 34 is equal to the width of the fixed slide 24, and the connecting lever 34 drives the grooved wheel 23 to rotate 90 degrees through the fixed slide 24.

[0030] Working principle: When laying waterproof membrane on the roof of a building, the user can position the equipment on the roof structure and guide the required membrane to be laid onto the building using the material guide device 2. Then, it is pulled by an external traction device. At this time, the support bracket 5 is moved on the top of the building under the drive of the traction device. Simultaneously, the material guide device 2 can gradually guide the waterproof membrane out. When the waterproof membrane wound by a set of material guide devices 2 is unwound, the operator can start the servo motor 31. The servo motor 31 can drive the limit turntable 33 and the connecting lever 34 to rotate one revolution. During the rotation, the limit turntable 33 can limit the limit groove 25. When the limit turntable 33 disengages from the limit groove 25, the connecting lever 34 can move the limit turntable 33 to rotate 90 degrees through the fixed slide groove 24, thereby enabling the connecting roller 21 to drive a new set of unwinding rollers 22 to rotate to the unwinding position. Then, the limit turntable 33 can lock the grooved wheel 23 again through the limit groove 25, which is convenient for subsequent feeding.
