[0002] Waterproof membranes are oil- and water-resistant roofing membranes. They are thin and do not alter the optical properties of anti-reflective film. They can be used for waterproofing building roofs. A cutting mechanism is used to cut the membrane during construction. Existing cutting mechanisms for waterproof membrane construction require disassembly of the entire shaft to load the membrane roll. After fitting the shaft and membrane roll, reassembly is required, which is time-consuming and labor-intensive, impacting actual efficiency. Therefore, a new waterproof membrane cutting mechanism is needed to address these technical drawbacks and improve performance. Utility Model Content

[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0005] The utility model is a cutting mechanism for a waterproof membrane, comprising:

[0006] The material loading structure includes a sliding frame, the sliding frames are symmetrically arranged in a group, and a sliding block is slidably provided in the upper end of the sliding frame, and a limiting column is fixed in the middle of both sides of the sliding block and extends out of the corresponding through-holes opened in the middle of both sides of the sliding frame. One end and the other end of the front of the sliding frame are respectively penetrated by an electric push rod 1 and an electric push rod 2, and the output end of the electric push rod penetrates the limiting column and extends to the innermost end of the inner wall of the through-hole, and a support plate is fixed to the upper end of the sliding block;

[0007] The cutting structure includes a cutting block, and the cutting block is arranged above the inner side of the support plate.

[0008] Furthermore, the material placement structure also includes a shaft rod, which symmetrically passes through the central position of the upper end of the support plate, and the inner end of the shaft rod is sleeved with a sleeve column, which extends to the middle of the waterproof membrane roll.

[0009] Furthermore, the cutting structure also includes a connecting column, one end of which is symmetrically fixed to one side of the upper end of the support plate, and the other end of the connecting column is fixed with a connecting block, the lower end of the connecting block is fixed with a guide frame, and a guide block slides in the middle of the guide frame.

[0010] Furthermore, an adjusting column is provided through the thread in the middle of the guide block, and the lower end of the adjusting column is sleeved with the upper end of the cutting block.

[0011] Furthermore, it also includes a support structure, which includes a support seat, the end of the upper end of the support seat is threadedly connected to the bottom end of a group of sliding frames, and support plates are fixed to the lower parts of the front and rear ends of the support seat, and the support plates are flush with the support seat.

[0025] See also Figure 1-4 As shown, the utility model is a cutting mechanism for a waterproof membrane, comprising:

[0026] The material loading structure includes a sliding frame 21. The sliding frames 21 are symmetrically arranged in a group, and a sliding block 22 is slidingly provided in the upper end of the sliding frame 21. A limiting column 23 is fixed in the middle of both sides of the sliding block 22 and extends out of the corresponding through-holes in the middle of both sides of the sliding frame 21. An electric push rod 1 24 and an electric push rod 25 are respectively passed through one end and the other end of the front of the sliding frame 21, and the output end of the electric push rod passes through the limiting column 23 and extends to the innermost end of the inner wall of the through-hole. A support plate 26 is fixed to the upper end of the sliding block 22;

[0027] The sliding frame 21 supports the sliding block 22. The sliding of the sliding block 22 can facilitate the adjustment of the spacing of the shaft 27 to meet the needs of replacing the waterproof membrane roll. The resistance between the output ends of the electric push rod 1 24 and the electric push rod 25 and the limit column 23 can be used to structurally position the support plate 26 after sliding left and right.

[0028] The material placement structure also includes a shaft 27, which symmetrically passes through the center of the upper end of the support plate 26, and the inner end of the shaft 27 is sleeved with a sleeve 28, which extends to the middle of the waterproof membrane roll;

[0029] The shaft 27 is supported by the sleeve 28 and extends into the waterproof membrane roll by means of the sleeve 28, thereby meeting the requirements for positioning and rotating the waterproof membrane roll.

[0030] The cutting structure includes a cutting block 36, which is arranged above the inner side of the support plate 26;

[0031] The cutting block 36 is subjected to force to cut the waterproof membrane.

[0032] The cutting structure also includes a connecting column 31, one end of which is symmetrically fixed to one side of the upper end of the support plate 26, and the other end of the connecting column 31 is fixed to a connecting block 32, the lower end of the connecting block 32 is fixed to a guide frame 33, and a guide block 34 slides in the middle of the guide frame 33;

[0033] The connecting column 31 fixes the connecting block 32, and the connecting block 32 is used to fix the guide frame 33 structure. The sliding of the guide block 34 in the guide frame 33 can meet the needs of the cutting block 36 to cut the waterproof membrane at multiple positions.

[0034] An adjusting post 35 is threaded through the middle of the guide block 34, and the lower end of the adjusting post 35 is sleeved with the upper end of the cutting block 36;

[0035] The adjusting column 35 connected by thread fixes the cutting block 36, and the height of the cutting block 36 can be adjusted by the extension and contraction of the thread to meet the cutting requirements.

[0036] The support structure includes a support base 11, the upper end of the support base 11 is threadedly connected to the bottom end of a group of sliding frames 21, and support plates 12 are fixed to the lower parts of the front and rear ends of the support base 11, and the support plates 12 are flush with the support base 11;

[0037] The support base 11 cooperates with the support plate 12 to ensure the stability of the mechanism through contact with the ground under gravity and friction damping.

[0038] Working principle: When the waterproof membrane roll is used for loading, the controlled electric push rod 25 retracts the output end and contacts the resistance force of the limit column 23. At this time, an outward force can be applied to the support plate 26, and the sliding block 22 slides in the sliding frame 21 to disengage a set of shafts 27. Then, the waterproof membrane roll to be loaded is placed in the spacing between the shafts 27, and then a reverse force is applied to the support plate 26, so that the sleeves 28 are respectively sleeved and extended to the middle part of the waterproof membrane roll, and then the controlled electric push rod 25 is used to apply a resistance force to the limit column 23 to ensure the stability of the structure. Finally, force is applied to the guide block 34, relying on the back and forth linear motion in the guide frame 33 to act on the waterproof membrane through the cutting block 36 to complete the cutting.

[0039] This solution can complete the convenient and quick replacement of the waterproof membrane roll, saving time and effort, and helping to improve work efficiency.

[0040] See also Figure 1-4 As shown, this embodiment is based on the above embodiment and further includes an auxiliary cutting structure, which includes a hole block 41. A locking block 45 is fixed to the inner side of the rear end of the hole block 41, and the locking block 45 passes through a locking bolt passing through the middle, and the thread is inside one end above the outer side of the support plate 26. A torsion spring 42 passes through the front end of the hole block 41, and an adjustment plate 43 is fixed to the inner side of the torsion spring 42. A positioning slot frame 44 is fixed in the middle of one end of the adjustment plate 43.

[0041] The locking block 45 cooperates with the locking bolt to fix the hole block 41, that is, to fix the entire auxiliary cutting structure. The torsion spring 42 fixes the adjustment plate 43 and relies on its own elastic force to meet the adaptive angle adjustment of the positioning slot frame 44, thereby avoiding damage caused by hard contact between the cutting block 36 and the inner wall of the positioning slot frame 44. The positioning slot frame 44 can bear the waterproof membrane to be cut, which can reduce the cutting position deviation.

[0042] Working principle: When cutting the waterproof membrane using the cutting block 36, the position of the waterproof membrane to be cut is aligned with the upper end of the positioning groove frame 44. When a rotational force is applied to the adjusting column 35, the cutting block 36 moves downward and contacts the position of the waterproof membrane to be cut under the rotation of the thread.

[0043] This solution can reduce the deviation of the cutting position of the waterproof membrane, facilitate use and meet the needs.
