Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane technology, and in particular to a self-adhesive waterproof membrane. Background Technology

[0002] Self-adhesive waterproof membrane is a type of waterproof material made from self-adhesive rubber asphalt formulated with synthetic rubber such as SBS, tackifiers, and high-quality road petroleum asphalt as the base material, tough high-density polyethylene film or aluminum foil as the upper surface material, and peelable silicone-coated release film or silicone-coated release paper as the lower surface anti-sticking release material. It is a new type of waterproof material with great development prospects. It has the characteristics of low-temperature flexibility, self-healing and good adhesion performance. It can be constructed at room temperature, has a fast construction speed, and meets environmental protection requirements.

[0003] When installing waterproof membrane, workers need to hold the membrane and roll it out and apply it at the same time. Sometimes, after the workers finish applying the membrane, there is still some membrane left, so it needs to be cut. However, the existing waterproof membrane is relatively thick, and workers cannot guarantee the accuracy of the cut. This often results in uneven cut edges, which affects the aesthetics of the construction.

[0004] Therefore, we propose a self-adhesive waterproof membrane to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A self-adhesive waterproof membrane includes a membrane shell and a waterproof membrane disposed inside the membrane shell. The membrane shell has rotating openings on both sides, and the same shaft is rotatably installed in both rotating openings. The waterproof membrane is sleeved on the shaft, and the waterproof membrane includes a self-adhesive layer. A fixing shaft is fixedly installed on one side of the membrane shell, and a cutting mechanism is provided on the fixing shaft.

[0007] Specifically, a rotating gear is rotatably mounted on the inner side of the roll shell, and four grooves are provided on one side of the rotating gear. Four protrusions are provided on the outer side of the shaft, and the four protrusions are respectively adapted to the corresponding grooves.

[0008] Specifically, a linkage gear and a driven gear are rotatably installed on the inner side of the roll shell. The two sides of the linkage gear mesh with the driven gear and the rotating gear, respectively. A take-up roller is fixedly installed on one side of the driven gear, which can drive the take-up roller to rotate.

[0009] Specifically, a stop bar and a scraper are fixedly installed on the inner side of the roll shell.

[0010] Specifically, the cutting mechanism includes a turntable, a handle, and a cutting assembly. The turntable is rotatably mounted on the fixed shaft. Two rotating holes are opened on one side of the turntable. A handle is fixedly installed on one side of the turntable. A cutting opening is opened on one side of the roll shell. Guide openings are opened on both the upper and lower sides of the roll shell. Both guide openings are connected to the same cutting opening. A cutting assembly is provided inside the cutting opening.

[0011] Specifically, the cutting assembly includes two blade holders and two linkage columns. Blade holders are slidably installed on the inner side of the two guide ports, and linkage columns are fixedly installed on one side of each blade holder. The two linkage columns are slidably installed in corresponding rotating holes, and the corresponding blade holders can be moved by the two linkage columns.

[0012] Specifically, the waterproof membrane also includes a top isolation layer, a bottom isolation layer, a reinforcing layer, and a waterproof layer. The top and bottom sides of the self-adhesive layer are respectively provided with a reinforcing layer and a bottom isolation layer. The top of the reinforcing layer is provided with a waterproof layer, and the top of the waterproof layer is provided with a top isolation layer, which facilitates the prevention of debris from contaminating the waterproof membrane.

[0013] Specifically, one end of the bottom isolation layer is wound around the take-up roller, which facilitates the peeling of the bottom isolation layer by the take-up roller.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the cutting mechanism can cut the waterproof membrane, and the simultaneous cutting by the upper and lower blades can effectively ensure the neatness and aesthetics of the cut edges.

Rotating openings are provided on both sides of the membrane shell 1, and the same shaft 2 is rotatably installed in both rotating openings. The waterproof membrane is sleeved on the shaft 2. The waterproof membrane includes a self-adhesive layer 17. A fixing shaft 9 is fixedly installed on one side of the membrane shell 1, and a cutting mechanism is provided on the fixing shaft 9.

[0023] In this embodiment, a rotating gear 3 is rotatably installed on the inner side of the roll shell 1. Four grooves are provided on one side of the rotating gear 3, and four protrusions are provided on the outer side of the shaft 2. The four protrusions are respectively adapted to the corresponding grooves.

[0024] In this embodiment, a linkage gear 4 and a driven gear 5 are rotatably installed on the inner side of the roll shell 1. The two sides of the linkage gear 4 are respectively meshed with the driven gear 5 and the rotating gear 3. A take-up roller 6 is fixedly installed on one side of the driven gear 5, which can drive the take-up roller 6 to rotate.

[0025] In this embodiment, a stop bar 7 and a scraper 8 are fixedly installed on the inner side of the roll shell 1.

[0026] In this embodiment, the cutting mechanism includes a turntable 10, a handle 12, and a cutting assembly. The turntable 10 is rotatably mounted on the fixed shaft 9. Two rotating holes 11 are opened on one side of the turntable 10. The handle 12 is fixedly installed on one side of the turntable 10. A cutting opening is opened on one side of the roll shell 1. Guide openings are opened on both the upper and lower sides of the roll shell 1. Both guide openings are connected to the same cutting opening. A cutting assembly is provided inside the cutting opening.

[0027] In this embodiment, the cutting assembly includes two blade holders 14 and two linkage columns 13. Blade holders 14 are slidably installed on the inner side of the two guide ports, and linkage columns 13 are fixedly installed on one side of each of the two blade holders 14. The two linkage columns 13 are slidably installed in the corresponding rotation holes 11, and the corresponding blade holders can be moved by the two linkage columns 13.

[0028] In this embodiment, the waterproof membrane also includes a top isolation layer 15, a bottom isolation layer 16, a reinforcing layer 18, and a waterproof layer 19. The upper and lower sides of the self-adhesive layer 17 are respectively provided with a reinforcing layer 18 and a bottom isolation layer 16. The top of the reinforcing layer 18 is provided with a waterproof layer 19, and the top of the waterproof layer 19 is provided with a top isolation layer 15, which facilitates the prevention of debris from contaminating the waterproof membrane.

[0029] In this embodiment, one end of the bottom isolation layer 16 is wound around the take-up roller 6, so that the bottom isolation layer 16 can be peeled off by the take-up roller 6.

[0030] Working principle: In use, the worker passes one end of the waterproof membrane through the slit on one side of the membrane shell 1, and simultaneously peels off the bottom release layer 16 of the waterproof membrane that has passed through the slit. Then, one end of the bottom release layer 16 is wrapped around the scraper 8 and the stop bar 7 and then onto the take-up roller 6. The worker then places the waterproof membrane with the bottom release layer 16 removed into contact with the base surface. At this point, the self-adhesive layer 17 adheres to the base surface. The worker moves the membrane shell 1, causing the shaft 2 to rotate and unwind the waterproof membrane. Simultaneously, the rotation of the shaft 2 drives the rotating gear 3 to rotate, which in turn drives the linkage gear 4 to rotate. The linkage gear 4 then drives the driven gear 5. The rotation of the roller 6 causes the bottom isolation layer 16 to be wound up. After unwinding, the operator turns the handle 12, which in turn causes the turntable 10 to rotate, which in turn causes the two rotating holes 11 to rotate. The rotation of the two rotating holes 11 causes the corresponding linkage column 13 to move around the fixed axis 9 as the center. However, the other end of each linkage column 13 is fixedly equipped with a blade holder 14. Both blade holders 14 are slidably installed in the corresponding guide openings. Therefore, the two blade holders 14 can only move up and down. When the two blade holders 14 move closer to each other and move to the designated position, the blades at the bottom of the two blade holders 14 contact the waterproof membrane and cut it.

[0031] The technological advancements of this invention compared to existing technologies are: it can cut waterproof membranes, and by cutting simultaneously with the upper and lower blades, it can effectively ensure the neatness and aesthetics of the cut edges. Furthermore, the set winding mechanism can wind up the bottom isolation layer 16 of the waterproof membrane, greatly improving the practicality of the equipment.
