[0027] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0028] The utility model provides a trimming device for waterproof coiled material, comprising:

[0029] The cutter mechanism comprises a rotating shaft and a cutter disc, wherein the cutter discs are respectively arranged at both ends of the rotating shaft, and a plurality of cutters are arranged along the radial direction on the outer circumference of the cutter disc, and the cutters are detachably connected to the cutter disc;

[0030] The knife-changing mechanism is arranged on a side of the knife-cutting mechanism away from the waterproof coiled material, and the knife-changing mechanism comprises a rotatable crawler, on which a plurality of first clamps are arranged, and the first clamps are detachably connected to the knife-cutting mechanism;

[0031] The knife sharpening mechanism is arranged on a side of the knife changing mechanism away from the knife cutting mechanism. The knife sharpening mechanism includes a lifting grinding wheel. When the knife cutting is moved to the bottom of the knife sharpening mechanism by the crawler belt, the grinding wheel grinds the knife cutting.

[0032] The control unit is connected with the knife cutting mechanism, the knife changing mechanism and the knife sharpening mechanism.

[0033] Specifically, the edge trimming device includes a cutting mechanism, a cutting mechanism and a sharpening mechanism. When the cutting mechanism cuts the edge of the waterproof coil abnormally, the control unit starts the cutting mechanism to remove the cutting knife from the cutting mechanism, and rotates the crawler to install the polished cutting knife on the first fixture on the cutting mechanism, so that the cutting mechanism can cut the coil and improve the cutting quality to ensure that the coil is cut neatly; then, the crawler continues to rotate to transfer the cutting knife removed from the cutting mechanism to the bottom of the sharpening mechanism, and the side surface of the cutting knife is polished by the up and down movement of the grinding wheel, so that the polished cutting knife remains on the crawler, and when the cutting knife of the cutting mechanism needs to be polished again, the polished cutting knife is replaced on the knife disc again.

[0034] Optionally, the distance between the knife discs is the same as the cutting width of the waterproof membrane.

[0035] Specifically, the knife discs are arranged at both ends of the rotating shaft, and the knife discs are rotated together with the rotating shaft. During the rotation process, the knife discs carry multiple cutters to cut the edges of the waterproof membrane. After the side surfaces of the cutters contact the waterproof membrane, the waterproof membrane can meet the cutting size requirements.

[0036] Optionally, the cutting knives are evenly arranged on the outer circumference of the cutting disc, and the cutting knives are made of stainless steel.

[0037] Specifically, the cutters can be evenly arranged on the periphery of the cutter disc, so that there is room for the cutter changing mechanism to take out and install the cutter, and when the cutter disc drives the cutter to rotate, the cutter can contact each position of the waterproof membrane to the same degree, thereby ensuring the quality of the cutting edge of the waterproof membrane.

[0038] In one embodiment, five cutting knives are arranged on the knife disc, and the interval between adjacent cutting knives is 72 degrees. The cutting knives are made of stainless steel with a hardness between 55-58HRC. In this way, the cutting knives with high hardness can be easily sharpened under the drive of the knife disc.

[0039] Optionally, the rotating shaft is connected to a variable frequency motor.

[0040] Specifically, the variable frequency motor can drive the rotating shaft to rotate at different speeds. When the cutting surface of the cutter is not sharp enough, the output power of the variable frequency motor is increased to ensure the cutting efficiency and edge cutting quality of the waterproof membrane.

[0041] Optionally, the cutter disc is connected to the cutter via a second clamp, and the second clamp is connected to the air compressor via an air pipe, and the air pipe is arranged inside the cutter disc.

[0042] Specifically, a certain number of second clamps are provided on the cutter disc, and the second clamps realize the adsorption of the cutter through the operation of the air compressor. When the second clamp needs to clamp the cutter, the air compressor generates compressed air, which can fix one end of the cutter; when the second clamp needs to replace the cutter, it does not need to clamp the cutter, so the first clamp on the crawler can clamp the other end of the cutter and take the cutter away for grinding through the sharpening mechanism. The air of the air compressor is transported to the second clamp through the air pipe, and the air pipe is inserted into the cutter disc, which can ensure the stability of the air pipe connection.

[0043] Optionally, the first clamp is a pneumatic clamp, and the cutting knife and the surface of the track are perpendicular to each other.

[0044] Optionally, the crawler track is a steel crawler track.

[0045] Specifically, the track fixes the cutter on the track through the first clamp. When the first clamp contacts the cutter to be sharpened, the cutter and the track remain in a vertical state. When the first clamp carries the cutter from the lower side of the track to the upper side of the track, the movement of the grinding wheel is estimated to be parallel to the length direction of the cutter. When the cutter moves to the right below the sharpening mechanism, the track stops rotating. Since the track is a steel track with a certain support strength, the cutter stops completely and then moves up and down on the grinding wheel, so that the side of the cutter can be sharpened. The number of first clamps on the track is greater than the number of second clamps. Cutters are connected to multiple first clamps at intervals. These cutters are reserved for use after being sharpened. When the cutter on the cutter disc needs to be sharpened, the cutter on the cutter disc is first removed by the first clamp without the cutter, and then the track is rotated to send the sharpened cutter to the top of the second clamp, so that the second clamp can suck the cutter.

[0046] Optionally, the knife sharpening mechanism comprises a hydraulic station and a telescopic cylinder, and an output end of the telescopic cylinder is connected to the grinding wheel.

[0047] Optionally, a rotating motor is arranged between the telescopic cylinder and the grinding wheel.

[0048] Specifically, the knife sharpening mechanism includes a telescopic cylinder and a rotary motor. When the cutter to be sharpened moves to the bottom of the knife sharpening mechanism, the outer surface of the grinding wheel forms a tangent positional relationship with the side of the cutter. The rotary motor is started to rotate the grinding wheel, and then the telescopic cylinder drives the rotating grinding wheel to move up and down, so that the grinding wheel can grind the cutter until it reaches a sharp state.

[0049] In one embodiment, the rotating shaft can drive the cutter disc to rotate in both clockwise and counterclockwise directions, and both sides of the cutter can cut the waterproof membrane. When the cutter is worn, the cutter will be replaced by the cutter changing mechanism, and the cutter sharpening mechanism can grind both sides of the cutter through the grinding wheel according to the wear of the cutter.

[0050] Optionally, the rotation speed of the rotating motor is 30-100 rpm / min.
