A telescopic spring is arranged between the block and the chute, the

A first connecting rod is installed on the slider, and a second connecting rod is installed on the upper end of the pressing bracket under the sliding groove. The first connecting rod and the slider are rotationally connected with the slider, and the second connecting rod is connected to The press-coated bracket is connected by a bearing rotation and utilizes the elasticity of a telescopic spring, so that it is suitable for different sizes.

10. Preferably, the pressing assembly includes a first pressing roller and a second pressing roller, a second pressing roller is arranged below the first pressing roller, and the first pressing roller is connected to the first pressing roller. The connecting rod is fixedly connected, the second pressing roller is fixedly connected to the second connecting rod, and the surface of the waterproof coiled material is pressed and covered by the pressing component to maintain the flatness.

11. Preferably, there are two discharging brackets located on the front and rear sides of the cutting table, the inner sides of the two discharging brackets are rotatably connected with a first rotating rod through a bearing, and the inner side of the discharging bracket is located at the first rotating rod. A second rotating rod is rotatably connected under a rotating rod through a bearing, and the surfaces of the first rotating rod and the second rotating rod are fixedly connected with a feeding roller, and the feeding roller is symmetrically arranged with respect to the horizontal center line of the waterproof membrane body There are two, using the rotation of the feed roller to adjust the cutting length of the waterproof membrane, which is convenient for controlling the cutting size.

12. Preferably, two transmission boxes are symmetrically arranged on the front and rear sides of the cutting table, a driving gear is installed inside the transmission box, and a driven gear is installed inside the transmission box on the side of the driving gear. , The driving gear is in meshing connection with the driven gear, a rotating handle is installed on the upper end of the transmission box, one end of the rotating handle passes through the transmission box and is fixedly connected to the driving gear, and the two driving gears are respectively connected to the first rotation The front and rear ends of the rod are fixedly connected, and the two driven gears are respectively fixedly connected to the front and rear ends of the second rotating rod. By rotating the handle, the gears are driven to rotate, and the synchronous rotation of the two feeding rollers is realized, thereby driving the waterproofing The coil moves.

13. Preferably, the cutting assembly includes a base, a cutting slot, a limit bracket, and a limit roller. The upper end of the base is provided with a cutting slot, and the side of the base is fixedly connected to the limit bracket, and the limit bracket The inner side of the bearing is rotatably connected with the limit rollers, the limit brackets are symmetrically arranged with two groups about the vertical center line of the base, and the limit brackets of each group are located on the front and rear sides of the base. Two rollers are symmetrically arranged with respect to the vertical center line of the base. The limit roller is adapted to the body of the waterproof membrane. The cutting groove and the cutting tool are adapted to each other. The limit roller is used to keep the waterproof membrane during cutting. The flatness of the waterproof membrane will not be excessively deformed by force.

14. Preferably, there are two symmetrically arranged electric telescopic rods, the fixed ends of the two electric telescopic rods are fixedly connected with the protective cover, and the telescopic ends of the two electric telescopic rods are fixedly connected with the cutting tool, using electric The telescopic rod pushes the cutting tool to cut, the operation is convenient and simple, and the safety is high.

15. Compared with the prior art, this utility model provides a cutting device for hand-cutting waterproof coiled material, which has the following beneficial effects:

16.1 The cutting device for the waterproof coiled material of the anti-cutting hand uses a fixed bracket to fix the waterproof coiled material, so as to cooperate with the feeding roller to discharge the material, pull the coiled material out of the appropriate length size, and use the electric telescopic rod to push the cutting The cutting tool moves to realize automatic operation. During the cutting process, personnel do not need to manually fix and cut, which improves the safety and cutting efficiency of the cutting device.

17.2 The cutting device for the cut-proof waterproof membrane uses a pressing roller to squeeze the surface of the waterproof membrane to make it smooth, and the limit roller limits the waterproof membrane, so that the waterproof membrane remains during cutting. Good flatness, and the waterproof membrane will not deviate, ensuring the accuracy of cutting.
