[0004] Based on the findings in the prior art, most of the existing waterproof roll cutting equipment has a simple structure and cannot stably limit the waterproof roll during the cutting process, which causes the waterproof roll to easily shift and skew during cutting, thereby affecting the cutting accuracy. The practicality is not high, and the cutting tools are generally installed by bolts, which is not convenient for regular maintenance and replacement after the cutting tools become blunt, and is inconvenient to use. Therefore, the utility model proposes a waterproof roll cutting equipment to solve the problems existing in the prior art. Utility Model Content

The mounting seat 5 and the cutting tool 6 are clamped and positioned by an elastic positioning mechanism, so that the cutting tool 6 can be conveniently disassembled and assembled at the bottom of the mounting seat 5. Spring ejectors 7 are provided on both sides of the mounting seat 5 and are symmetrically distributed front to back. The top of the spring ejector 7 is fixed to the bottom end of the lifting plate 4 by bolts. The bottom end of the spring ejector 7 is fixed with a coil pressing plate 8 for pressing the waterproof membrane by bolts. The bottom end of the coil pressing plate 8 is fixed with a rubber anti-slip block 9 which plays an anti-slip role. The lifting plate 4 is driven by the hydraulic cylinder 3 to drive the cutting tool 6 at its bottom to descend and cut the waterproof membrane. At the same time, under the extrusion force of the spring ejector 7, the waterproof membrane is pressed and fixed to a certain extent by the coil pressing plate 8 and the rubber anti-slip block 9, so that the waterproof membrane is stably limited during the cutting process.

[0023] The outer walls of the front and rear sides of the lifting plate 4 are welded and fixed with limit slides 10 that are symmetrically distributed on the left and right. The inner walls of the front and rear sides of the support cover 2 are symmetrically provided with limit slide grooves 11. The limit slide grooves 11 are adapted to the limit slides 10. The limit slides 10 are slidably arranged in the limit slide grooves 11 to play a limiting role, making the lifting plate 4 more stable during the lifting process.

[0024] The bottom end of the mounting base 5 is provided with an engaging groove adapted to the cutting tool 6 so that the upper part of the cutting tool 6 can be engaged and inserted into the interior of the mounting base 5. The elastic positioning mechanism includes a square frame 13 and a positioning pin 14, wherein the square frame 13 is provided with two groups and is fixed to the outer walls of the front and rear sides of the mounting base 5 by screws. The positioning pin 14 is provided with two groups and slides through the frame 13 respectively. The upper part of the outer walls of the front and rear sides of the cutting tool 6 is provided with a positioning hole 15 and the positioning hole 15 is adapted to the positioning pin 14. The opposite end of the two groups of positioning pins 14 slides through the interior of the mounting base 5 and extends to the positioning hole 15, the cutting tool 6 is positioned and fixed by inserting the positioning pin 14 into the positioning hole 15, and the positioning pin 14 is located on the outside of the square frame 13 and is welded and fixed with a pull ring, which is convenient for the user to pull the positioning pin 14, and the positioning pin 14 is located on one side of the square frame 13 and is fixedly sleeved with a baffle 16, and a linear spring is fixed between the baffle 16 and the inner wall of the square frame 13 away from the mounting seat 5, and the linear spring is slidably sleeved on the positioning pin 14, and the linear spring is used to provide an elastic ejection force for the baffle 16, so that the positioning pin 14 is automatically pushed into the positioning hole 15, which is convenient and easy.

[0025] The spring ejector 7 includes a sleeve 701 symmetrically fixed to the bottom end of the lifting plate 4 by bolts and a telescopic rod 702 symmetrically fixed to the top of the coil pressing plate 8 by bolts. The top of the telescopic rod 702 is slidably arranged inside the sleeve 701. A limiting spring 703 is fixed between the top of the telescopic rod 702 and the top of the sleeve 701. The limiting spring 703 provides a downward elastic ejection force for the telescopic rod 702, thereby driving the telescopic rod 702 and the coil pressing plate 8 to descend and press the waterproof coil.

[0026] A cutting groove 17 adapted to the cutting tool 6 is provided at the top of the cutting table 1, and a through groove 18 is provided on both the left and right sides of the top of the cutting table 1. Rotating rods 19 equidistantly distributed laterally are rotatably connected in the through groove 18 through bearings to provide rolling support for the waterproof membrane, making it easy to push. Concave limiting plates 20 symmetrically distributed on the front and rear sides of the through groove 18 are fixed to the top of the cutting table 1 by bolts. Through holes 21 equidistantly distributed laterally are provided on the side walls of the concave limiting plates 20. Rollers 22 are rotatably connected in the through holes 21 through bearings to limit the front and rear sides of the waterproof membrane through the concave limiting plates 20 to prevent it from shifting during movement.

[0027] When the waterproofing roll material needs to be cut, the waterproofing roll material to be cut is first placed on the left side of the top of the cutting table 1 and is between the front and rear two sets of concave limit plates 20. Then, the waterproofing roll material is pushed from left to right until the cutting position moves to under the cutting tool 6 inside the support cover 2. At this time, the hydraulic cylinder 3 is started to drive the lifting plate 4 to descend. During the descending process of the lifting plate 4, the cutting tool 6 is driven to descend and cut the waterproofing roll material. After cutting, the waterproofing roll material is continued to be pushed until the cutting process of the entire waterproofing roll material is completed. Before each cutting process, since the roll material pressing plate 8 is located under the cutting tool 6, the roll material pressing plate 8 and the rubber anti-sliding block 9 will contact the waterproofing roll material before the cutting tool 6, and press and fix the waterproofing roll material under the extrusion of the spring ejector 7 (while pressing, due to the retractability of the spring ejector 7, it will not affect the descent of the cutting tool 6), so that the waterproofing roll material remains stable during the cutting process;

[0028] When the cutting tool 6 needs to be replaced after a long period of cutting processing, the elastic positioning mechanism is used to release the fixed connection between the cutting tool 6 and the mounting seat 5, and then the cutting tool 6 is directly taken out from the fitting groove at the bottom end of the mounting seat 5 to complete the disassembly, and then the new cutting tool 6 is fitted and installed to the bottom end of the mounting seat 5, and the elastic positioning mechanism is used to fit the cutting tool 6 and the mounting seat 5 to achieve convenient installation of the cutting tool 6.
